Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is used as a place for pet animals (e.g. dogs, cats, etc.) kept at home, especially indoors, to urinate (pet toilet place). ``Regarding improvement of double-structured toilet box 1''.

The pet litter box of the present invention is suitable as a litter box for pet animals kept indoors because it can prevent urine odor from occurring and the used deodorizer can be easily disposed of. It can be used for.

[Description of prior art]

In general, when pet animals are kept indoors, there are various problems regarding the treatment of excrement and urine produced by the pet animals, and various methods for dealing with these problems have been studied and proposed.

For example, litter boxes for pet animals such as dogs and cats may have pebbles or river sand placed inside them as litter, or paper-processed materials made from waste paper, pulp, etc. formed into granules may be used as litter. There are products on the market that have the pebbles, river sand, etc. placed inside the toilet box as litter, but with those, the litter needs to be replaced frequently, and the used litter must be thrown away. There are also problems such as difficulty in finding a place to use the litter, and the paper-processed materials used as litter placed inside the litter box are lighter than the litter made of pebbles or river sand, and can easily fall apart. The problem is that the pet animal's body and limbs can stain the room, making it difficult to handle.

On the other hand, a pet litter box has been proposed in which the litter box is covered with a lid, a ventilation hole is provided in the lid, and an activated carbon filter is placed in the hole, but the urine odor generated is not completely eliminated. The above-mentioned problems also occur when replacing the litter placed inside the toilet box.

By the way, as a litter box for pet animals that improves these drawbacks, an inner box that forms a defecation chamber, the upper part of which is filled with a water-absorbing material with numerous voids such as litter or zeolite, and this inner box are fitted. It consists of an outer box that is deeper than the inner box so that a storage chamber can be formed below the inner box. A drainage port large enough to prevent the member from falling is opened, and the upper surface of the bottom of the defecation chamber is sloped downward toward the drain port. The toilet box is double-layered, with a deodorizer filled in a rope bag built into the reservoir, and a defecation port closed with a valve that can be opened and closed. , was proposed in Japanese Utility Model Application Publication No. 61-100975.

However, in the above-mentioned known double-structured toilet box, a small amount of pet animal urine is impregnated or attached to the water absorbing member, and a large amount of urine that is not impregnated or attached passes through the water absorbing member, flows down, and accumulates. However, these urine components tend to decompose and ferment in a short period of time, producing an extremely unpleasant odor (odor), and the deodorizer in the storage chamber at the bottom of the container must be replaced quite frequently. When replacing it, first open the defecation port valve and drain the accumulated urine, then sprinkle water on the water absorption member to clean it, and thoroughly clean the storage chamber to reduce the bad odor inside the storage chamber. There was a problem in that it was not easy to remove the inner box from the outer box and take out the deodorant.

[Problem to be solved]

As mentioned above, known double-walled toilet boxes generate unpleasant odors due to the decomposition and fermentation of urine when used for a short period of time, and the deodorizing agent filled inside the toilet box needs to be replaced frequently. However, there has been a need for a litter box for pet animals that solves this problem.

An object of the present invention is to provide a toilet box that can prevent the generation of unpleasant odors due to decomposition and fermentation of urine, and also allows easy replacement of used deodorant.

[Means for solving problems]

This invention includes a transparent material layer that is open at the top and filled with a transparent material to allow the undiluted solution released by a pet animal to pass through and flow down; The receiving cavity is separated by a partition member, and the partition member is provided with numerous openings that are sized to prevent the transparent material from falling, and the upper transparent material is passed through the openings. A double-structured toilet box for pet animals to urinate, comprising a container in which a layer and a lower urine receiving cavity are connected to each other,
A toilet box for pets, characterized in that a drawable bottom-shaped container, which is open at the top corresponding to the partition member and filled with a deodorizer, is installed in the urine receiving cavity. Regarding.

[Detailed explanation of each requirement of the present invention]

Hereinafter, the 17 boxes of pet toys of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is an overall partially cutaway perspective view showing an example of the toilet box of the present invention, and FIG. 2 is a sectional view taken along the line AA in FIG. 1.

In the toilet box of the present invention, for example, as shown in FIGS. 1 and 2, the upper part of a partition member 5 provided with numerous openings 51 is filled with a permeable material 4 that allows various undiluted solutions to pass therethrough. It has a permeable material layer 31 on the upper part, and the lower part of the permeable material layer 3 contains urine that has passed through the permeable material layer 3 and drained through the opening 51 of the partition member 5. A toilet box 1 having a double structure having a "urine receiving cavity 6" for receiving urine can be mentioned.

That is, in the toilet box l of the present invention, the partition member 5 is provided on the entire horizontal surface along the bottom surface 22 of the box-shaped container 2 in the middle of the side wall 21 of the box-shaped container 2 which is open at the top. The formed upper space with an open top is used as a transparent material layer 3, and the space between the partition member 5 and the bottom surface 22 of the box-shaped container 2 is used as a urine receiving cavity 6. It is.

The above-mentioned transparent material layer 3 is for pet animals to urinate directly on the transparent material layer, and the inside of the upper space of the box-shaped container 2 which is open at the top is filled with the transparent material 4. However, the permeable material 4 may be made of any material as long as it allows the undiluted solution released from the pet animal to permeate and quickly flow downward, for example, Examples include paper sand, filters made of woven or non-woven fabrics made of long and short fibers, or toilet litter such as river sand, gravel or pebbles with an average particle size of about 0.5 to 10flII11, especially about 1 to 8 rm. . Therefore, as the above-mentioned transparent material layer 3, one having a structure in which these transparent materials are filled inside the open upper space of the box-shaped container 2 can be preferably mentioned, and particularly, , the structure filled with the above-mentioned litter is most preferable.

Furthermore, in the present invention, the permeable material 4 is substantially insoluble in water and has water repellency when attached to the entire surface of the litter, and is suitable for pet animals. It is also possible to use litter that has been treated with a "repellent agent" that is substantially non-toxic.

The thickness of the transparent material layer 3 is about 10 to 60 mm,
In particular, it is preferably about 25 to 40 mm.

Next, the r partition member 5j that partitions the permeable material layer 3 and the urine receiving cavity 6 in the box-shaped container 2 will be explained.

As mentioned above, the partition member 5 is connected to the side wall 2 of the box-shaped container 2.
1, it is attached to the entire surface of the box-shaped container 2 in the horizontal direction along the bottom surface 22, but its attachment position depends on the size of the box-shaped container 2 and the urine receiving cavity 6, as will be described later. The height should be changed as appropriate depending on the amount of stock solution stored in the container, but it is desirable that the height from the bottom surface 22 of the box-shaped container 2 be at least several tens of meters or more.

In the above mounting position, the support frame 52 horizontally protruding from the side wall 21 toward the inside of the box-shaped container 2 extends over the entire circumference of the side wall 21, or
The support frame 52 is provided in one pair of directions, vertically and horizontally, and furthermore, the thickness of the partition member 5,
Alternatively, when the partition member 5 is placed on a reinforcing support frame 55 (described later), the side wall is placed at a distance slightly larger than the total thickness of the partition member 5 and the reinforcing support frame 55 in the same manner as the support frame 52. A fixed frame 53 protruding horizontally from 21 toward the inside of the box-shaped container 2 is attached to the side wall 21 .
The partition member 5 is placed and fixed between the support frame 52 and the fixed frame 53, and is provided around the entire circumference of the support frame 52 or in either the vertical or horizontal directions corresponding to the support frame 52. It is.

As described above, the partition member 5 has numerous openings 51 large enough to prevent the above-mentioned transparent material 4 filled in the upper part from falling, and to prevent the partition member 5 from loosening due to the weight of the transparent material 4, etc. It may be of any structure as long as it has a structure such as a perforated plate, a net, etc., but in this invention, the net 5
The use of 4° is preferred. In addition, when using the net body 54, both ends of the net body 54 are placed on the support frame 52, and the net body 54 is placed on the support frame 52 so that the rope body 54 does not loosen due to the weight of the transparent material 4 etc. filled in the upper part of the net body 54. , it may be placed on reinforcing support frames 55 provided at appropriate intervals in either the vertical or horizontal directions.

The mesh size of the net 54 is not particularly limited as long as it is large enough to prevent the transparent material 4 from falling, and can be changed as appropriate depending on the type of transparent material 4 used. When the above-mentioned toilet litter is used as the permeable material 4, the mesh size is preferably about 7 to 14 meshes.

In the toilet box of the present invention, as described above, the partition member 5 forming the bottom surface of the transparent material layer 3 is connected to the bottom surface of the toilet box 1.
For example, in a preferred embodiment of the present invention, a net 54 is provided horizontally along the bottom surface 22 of the toilet box 1 as the partition member 5. By providing it horizontally, the raw solution that has passed through the permeable material layer 3 and flowed down can be quickly drained into the lower urine receiving cavity 6 through the opening 51, but the effect is In order to further increase the water efficiency, the partition member 5 is not provided with countless openings, but has a drainage port opened only in the center thereof, and the partition member 5 is inclined in a funnel shape toward the drainage port. In addition, in the middle of the inclined part, along the bottom surface 22 of the toilet box 1, the entire surface in the horizontal direction,
It is also possible to use a net with the specifications shown above (not shown in the drawing). In this case, the inclination angle of the partition 5 is determined by the depth of the peripheral edge of the transparent material layer 3, the type and amount of the transparent material 4 to be filled, and the upper space of the box-shaped container 2 forming the transparent material N3. Considering the size of the liquid, the flow rate of the stock solution, etc., the
It is desirable to set the angle to 45 degrees, preferably about 4 to 30 degrees.

On the other hand, as described above, the urine receiving cavity 6 of the toilet box l has an opening at the top corresponding to the partition member 5, and communicates with the transparent material layer 3 through the opening 51 of the partition member 5. , for storing the undiluted solution flowing down from the transparent material layer 3, and a deodorant 71, which will be described later, is provided in the space between the partition member 5 and the bottom surface 22 of the box-shaped container 2.
It is formed by inserting a drawable bottom-shaped container (hereinafter abbreviated as "bottom-shaped container") 7 filled with R.

In order to prevent the odor from the undiluted solution accumulated in the bottom-shaped container 7 from escaping outside the toilet box 1,
The side wall 21 of the box-shaped container 2 has a cross-sectional outer shape of the bottom-shaped container 7, which is formed by a plane perpendicular to the direction in which the bottom-shaped container 7 is inserted and taken out. is opened in a shape substantially equal to that of the container, and when the bottom-shaped container 7 is inserted, the side wall 21 and the side wall 72 on the loading/unloading side of the bottom-shaped container 7 are flush with each other, and further, The opening of the insertion part of the bottom-shaped container 7 provided in the side wall 21 and the bottom-shaped container 7
It is desirable that a sill portion 23 be provided in the gap formed between the two.

The structure of the seal part 23 is not particularly limited, but for example, a sealing material such as a gasket is attached to the periphery of the opening of the side wall 21, and the bottom-shaped container 7 is inserted into the opening. For example, the gap between the container 7 and the bottom-shaped container 7 can be sealed.

Further, it is preferable that a handle 73 is provided on the side wall 72 on the loading/unloading side of the bottom-shaped container 7 in order to facilitate loading/unloading.

Note that the reason why the bottom-shaped container 7 is shaped like a boat-bottom is as follows.
This is to ensure that the undiluted solution comes into sufficient contact with the deodorant 71 and to allow the deodorant 71 to be easily replaced by the method described below.

By the way, in the toilet box 1 of the present invention, the box-shaped container 2, the support frame 52, the fixed frame 53, the partition member 5 such as a perforated plate or a mesh body 54, the reinforcing support frame 55,
The bottom-shaped container 7 and the like need only be made of a material that is not easily corroded by urine components. For example, the box-shaped container 2, the support frame 52, the fixed frame 53, and the bottom-shaped container 7 etc. are preferably made of steel plates such as stainless steel, or resins such as vinyl chloride, polyethylene, polypropylene, etc., but the above-mentioned materials are easy to manufacture and inexpensive. Particularly preferred is one made of resin, and the partition member 5, reinforcing support frame 55, etc. are preferably made of stainless steel.

Furthermore, in this invention, in order to confirm the amount of stock solution accumulated in the bottom-type container 7,
Although it is preferable that a viewing window 74 is provided in the side wall 72 on the loading/unloading side, the means for checking is not particularly limited to this. It may also be made of transparent resin such as resin.

A deodorizer 71 filled in the bottom-shaped container 7
The replacement is performed when it is confirmed by the above-mentioned means that the bottom-shaped container 7 is almost full of stock solution, or when the upper part of the box-shaped container 2 forming the transparent material layer 3 is opened. Transparent material 4 filled inside the upper space
It is recommended that you do this when the urine odor emanating from the urine gets worse.

Note that in order to replace the deodorizer 71, the bottom-shaped container 7 is removed from the box-shaped container 2, and the used deodorizer is removed from polyethylene, polypropylene, etc. together with the undiluted solution accumulated in the bottom-shaped container 7. Either pour it into a commercially available container made of resin such as and cap it, or pour it into a garbage bag made of polyethylene or polypropylene and tie the opening.
It is designed to be easily disposed of and incinerated together with household waste (garbage, etc.), while the empty boat-bottom type container 7 is cleaned after thoroughly cleaning the inside as necessary. All you have to do is fill the required amount of new deodorant and then insert it into the box-shaped container 2.

In this invention, the undiluted urine of the pet animal may adhere to the permeable material 4 filled in the open upper space of the box-shaped container 2 and emit an odor. If a small amount of the undiluted solution adheres to the permeable material 4, sprinkle a small amount of water over the permeable material 4 with the ship bottom type container 7 inserted, and remove the stock solution from the ship bottom type container 7.
The deodorizing effect of the toilet box 1 of the present invention can be extended by washing it inside. Furthermore, when replacing the deodorant 71, after removing the bottom-shaped container 7 from the box-shaped container 2, the inside of the upper space of the box-shaped container 2, which is open at the top, is filled. Transparent material 4
By pouring water over the permeable material 4, washing the permeable material 4 with water, drying it, and reusing it, the life of the permeable material 4 until replacement can be extended. Note that this method can be suitably used when toilet litter as described above is used as the permeable material 4.

By the way, the above-mentioned deodorant 7 used in this invention
1, rice husks are heated under an inert gas atmosphere to about 200 to 7
A smoked carbonized product of rice husk produced by heating the rice husk to a high temperature of 00° C. to smoke and carbonize the rice husk is preferable in terms of its deodorizing effect.

The smoked carbonized rice husks contain carbon in a proportion of 55 to 75% by weight and ash in a proportion of 5 to 20% by weight, and have a specific surface area of 4 to 10 rrr/g. , the pH value of the cleaning solution when cleaning with neutral water is 6.0.
The optimum value is about 8.5.

The smoked carbonized product of the rice husks is obtained by heating the rice husks at high temperatures to carbonize the rice husks as described above, then immersing the smoked carbonized products in an alkaline aqueous solution, and then washing thoroughly with neutral washing water. can be manufactured.

In this invention, the amount of the deodorant used is preferably 0.05 to 1 part by weight, preferably 0.1 to 0.5 part by weight, per 1 part by weight of the pet animal stock solution. The amount of the permeable material 4 to be used is approximately 5 to 50 parts by weight per 1 part by weight of the deodorant.
It is desirable to change it appropriately depending on the type.

Further, in the present invention, the deodorant 71 and the transparent material 4 contain a disinfectant or preservative, such as p-nonylphenol or benzalkonium chloride, which is substantially harmless to pet animals. (The amount of these disinfectants or preservatives added or attached can be changed as appropriate depending on the amount of urine urinated by the pet animal, but for example, it is preferably about 0.1 to 10 g per 1 kg of deodorant or permeable material.) , ) may be added or attached.
