Abstract

PURPOSE:To enable easy changing of an ejection pattern in a dispenser which can eject mist or foam by providing a member for closing the opening end of a specific slit during rotation of a nozzle together with a cap in the bottom of a nozzle base. CONSTITUTION:When a nozzle cap 24 is turned to a foam position, a nozzle groove 28 communicates with a flow passage 30 of a nozzle base and sucks up the liquid in a container 14 as a trigger 12 turns. The liquid is discharged through flow passages 26, 28, 30, a slit 42 and broad passage 40 from an orifice 18 so as to be ejected as foam from a central hole 48 by the air from the air supply line between a nozzle 22 and a cap 24. When the cap 24 and the nozzle 22 are both turned additionally by 90 deg., a groove 39 communicates with a flow passage 30, and the pressurized liquid flows directly into the slit 40 without causing pressure drop and is sprayed from the hole 48 after it is atomized by the orifice 18. When the cap and nozzle are turned additionally by 90 deg., the device comes to off-state.

Description

[Detailed description of the invention] This invention relates to a disk.

Generally, dispensers are configured to dispense a jet of pressurized liquid.

However, dispensers are also known in which a spinner or foam generating means is disposed adjacent to the inside or outside of the orifice of the dispenser to atomize or foam the liquid. In addition to single-function dispensers, two types of multi-function dispensers have been developed that selectively dispense liquid as either a jet, a mist, or a foam.

Type 0 dispensers, which select either jet or mist, generally produce a nozzle by rotating the nozzle. Switching turns. In the case of a type in which either fog or foam is selected, the pattern is generally changed by attaching and detaching the nozzle cap. As described above, in the latter case, since the ξ-turn is changed by attaching and removing the nozzle cap, the 9-turn changeover is troublesome and has the disadvantage that the nozzle cap is easily lost.

Is this issue 191 a fog? The purpose of the present invention is to provide a device that can easily change patterns between 1 and 2 without causing loss of the nozzle cap or the like.

Embodiments of the present invention will be described below with reference to the drawings.

In the embodiment, the dis-sense sensor 10 is formed on trigger tights 0, as shown in the first section to FIG. In other words, by rotating the trigger 12, the piston slides inside the cylinder 7, sucking the powder in the container I4 into the cylinder and pressurizing it. The pressurized liquid is turned into a vortex and directed through the orifice 18 (see FIG. 4). The dispersion server 10 is characterized by its nozzle portion, and the configuration from the container 14 to the spinner 16 is well known (for example, Japanese Utility Model Publication No. 57-31965), so the details will be omitted. Hiko's massager (not limited to trigger tights 0, but also uses from gas)/this aerosol type, sliding) 0. It may also be configured as other types such as the Fushon 2 tongue tights 0 using the button and the Ponno 0 type using the Pon 70 mechanism.

As shown in Figure 4, the nozzle part of the dispenser 10 is connected to a fixed nozzle base 2 (
It is composed of a nozzle 22 and a nostle canop 24, each of which has a high capacity. The nozzle base 20 (is formed into a cylindrical shape with a bottom) and is fixed to the dispenser main body so that the bottom is located at the external force, and the sillage part 21 of the nozzle base is formed into a cylindrical shape with a bottom. The nozzle base 20 has an axial flow passage 26 in which a secondary valve spring 5 is disposed, and one end communicates with the flow passage 26 and the other end is closed. The radial flow path 30 has one end communicating with the flow path 28 and the other end being open. As shown in Figure 5, a pair of #+1 base members 3, leaving gear )0C

(d: As described later, ((Used as a flow path for force 11 pressure dispersion.

- Soil nozzle 22 V'i As shown in FIG. 4, it is formed into a bottomed cylindrical shape having a bottom 33 with an orifice 18 formed therein. An annular protrusion 34 is formed at the outer end of the inner peripheral surface of the nozzle 22, and the protrusion forms a slot 34 on the outer periphery of the nozzle base.
When it is engaged with 6, it becomes impossible to slide, but it rotates 7 times.
It is attached to the nozzle head 20 in the j3 function. Also, at the inner end of the inner peripheral surface of the nozzle 22, as shown in FIG.
A pair of groups 3839 are formed 9Q' apart in the circumferential direction. These groups extend in the axial direction so as to be able to communicate with the flow path 30 of the nozzle base (see Fig. 4).
. In addition, an 11 square meter wide pickpocket connected to the orifice 18, 1.
40 and a pair of narrow slits 42 perpendicular to the slit 14° are formed in the center of the bottom 33 of the nozzle.

Since slits 40 and 42 have the same depth, slit 40.
The horizontal tonneau area is larger than the slit 42.

Here, one open end of the nozzle 4 (r) is located at group 39 on the inner surface of the nozzle at i,o'L. A pair of four blades 43 separated by 90 degrees in the circumferential direction and a pair of other blades 44 arranged in the center between the blades are provided on the outer peripheral surface. Grate +42 is between blades adjacent to JI゛ (forms a supply path for foaming air, blade 44 is a cylindrical nozzle 2)
2 acts as an engagement means to ensure that the nozzle gear rotates integrally with the nozzle gear [024].

As shown in FIGS. 4 and 9, the nozzle gear 24 is formed into a cylindrical shape with a bottom 46 (-1) having a circular cross section and a Yamada end face 5 having a rectangular cross section.
It has a medium hole 48, and a sill 50 concentric with the center hole is formed at the bottom and extends in the axial direction. This cylinder 50
acts as a barrier wall 7 for foaming. However, the barrier wall for foaming is not limited to the shape of the cylinder 50, and may extend from the inner circumferential surface of the nozzle nozzle, and various shapes thereof may be considered. 9) Circumferential force between the outer circumferential surface of /Rin'l''50 and the inner circumferential surface of the nozzle gear, f24.
O0 4 blades 52 of 7 blades are formed, separated from each other, and extend at the end face J of the cylinder 5°, part of the grade. In this way, by extending the blade 52 at the end face 1 of the 7 cylinders at 5 degrees, the cylinder is prevented from forming a tight foil on the front surface of the nozzle, and an air supply path can be secured. Further, an annular projection 54 is integrally formed at the end of the inner peripheral surface of the nozzle gear horn, and when this projection is engaged with the nozzle, the nozzle cap is attached to the nozzle in a non-slidable manner. Furthermore, two sets of engagement claws 56 are formed at the corners of the inner peripheral surface of the nozzle gear horn 0, and these engagement claws are each formed from a pair of engagement pieces 58 that can be engaged with the blade 44 of the nozzle. (See Figure 10). By engaging the blades 44 with the engaging claws 56 in this way, the circular nozzle 22 can rotate integrally with the nozzle gear horn 24.

Disbenser 10JJ having the above configuration is utilized in the following manner. As shown in FIGS. 1 and 2, OFF is applied to the outer peripheral surface of the nozzle cap 24.

When the nozzle cap is rotated, a suitable indication of NO of foam is obtained. For example, if the nozzle cap 24 is rotated so that the bubble image is on the top as shown in FIG. 1, the nozzle 22 will rotate together with the nozzle cap, and as shown in FIGS. As shown in FIG.
will be communicated to. Similar to a general dispenser, regardless of the rotational position of the nozzle cap 24 and nozzle 22, when the trigger 12 is rotated, the liquid in the container 14 is sucked into the cylinder and pressurized to flow through the flow path 26.28. It is then sent to the flow path 30. If the group 38 of nozzles and the channel 3o of the nozzle base are in communication, the pressurized liquid will flow from the group 38 through the slit 42 at the bottom of the nozzle and into the slit 4o, as best seen in FIG. 11A. Since the slit 4° is considerably wider and has a larger cross-sectional area than the slit 42, the pressure of the pressurized liquid decreases. Therefore, the pressurized liquid flowing out from the slot 4θ through the orifice 18 collides with the discharge tongue 1 and the cylinder 5θ acting as a barrier under a wide discharge angle as shown by the two-dot chain line in FIG. . Here, the pressurized liquid also collides with the bottom 46, but mainly collides with the cylinder 50. The pressurized liquid is mixed with air and is dispensed as bubbles from the central hole 48. In Fig. 11A, the nozzle gear 4 and the nozzle 22 are further connected to the nozzle 22 at the time i1. If the group 39 is rotated by 90 degrees in the direction, the group 39 is communicated with the flow path 30 (see Fig. 111'3). Slip)・40
flows directly into the However, through the slit 42,
y) When flowing into 4o, the pressure of the pressurized liquid is 1ii
The pressurized liquid is discharged from the orifice 18 under high pressure without dropping f. Therefore, the pressurized liquid is discharged under a narrow discharge angle as shown by the dashed line in FIG.
The mist is dispensed through the central hole 48 without colliding with the air conditioner 6. When the twisted nozzle gap 24 and nozzle 22 are rotated 90 degrees clockwise and then rotated 900 degrees clockwise, the flow path is 9θ.
Neither groups 38 nor 39 are connected (
1st. ], see Figure C and Figure 11D).

In these conditions, the pressurized liquid sent through the flow path 30'3.
- From then on, the Disconnector 10 is turned off immediately.

Needless to say, the number of slits 40, 40, f2 formed at the bottom of the nozzle, the layers, etc. are determined in relation to the equipment of Groups 3B and 39 JJ1 and above.

For example, as a modification of 40 and 42, the 12th
Figure A and Figure 12B are possible. In FIG. 12A, only one slit 42 is formed, and in FIG. 12B, two slits 42 are formed in parallel. In the modified example of FIG. 12B, the blockage part a)
The slit of tgi is blocked (~, when it is fog, it closes any slit and is rotated to fr'/-jij1'. Also, the group, ? 8, , ? 9 is 900 in the circumferential direction. Formed by separation, the number is 11'1''
