Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an oil level display device for a liquid fuel combustion device using a cartridge type fuel tank.

Conventional Technology A conventional example will be explained based on FIG.
A refueling tank receiver 103 having a diameter of 4 is fitted. 10
Reference numeral 5 denotes a fuel tank, and a base 107 equipped with a valve mechanism 106 is attached to the lower part of the tank, and the base 107 has a valve mechanism 106 attached thereto.
3, the valve mechanism 106 is pushed by the valve opening protrusion 104 and opens, so that the oil receiver is supplied with oil into the dish 101.

Reference numeral 108 denotes a sensing spring, which is applied with a biasing force to lift the fuel tank 105 upward when the fuel tank becomes lighter due to a decrease in the amount of oil in the fuel tank 105. 109 is a sensing lever, and support plate 11
1, and one end is supported by a support shaft 110 attached to 1.
09a is inserted under the fuel tank 105 so as to be lifted up, and a display section 112 is formed at the other end 109b. This display section 112 is provided with a display 113 using colors, letters, or the like. Reference numeral 114 denotes an exterior portion, which includes a display window 115 in a portion corresponding to the display portion 112.
is drilled so that when there is sufficient oil in the fuel tank 105, a display indicating this can be seen, and when the oil level decreases, the fuel tank 105 is lifted by the biasing force of the sensing spring 108 to the position shown by the dotted line. According to this movement, the empty capacity display on the display section 112 at the tip of the sensing lever 109 can be seen through the display window 115.

Problems to be Solved by the Invention However, according to the above conventional method, it is difficult to obtain relative positional accuracy between the position of the display window and the display section, so it is necessary to increase the display width of the display section, etc. This increased the space required, making it difficult to install in a narrow space, and the accuracy was not very good.

The present invention is intended to solve the above problems, and aims to reduce the size of the device and improve accuracy.

Means for Solving the Problems In order to achieve the above object, the present invention comprises a sensing lever that is linked to the vertical movement of the refueling tank with a thin spring plate. It has a structure in which guide parts are provided on both sides to prevent it from shifting in the direction.

Effect of the Invention With the above configuration, the present invention can reduce the installation space and improve display accuracy.

EXAMPLE Below, one example of the present invention will be described with reference to the drawings.
In Figures 3 to 3, ``■'' indicates an oil pan, and 2 indicates an oil holder, into which an oil tank holder 3 is inserted, and there is a valve opening projection 4 therein. 5 is a fuel tank, and a valve mechanism 6 is located at the bottom of the tank.
When the oil supply receiver is inserted into the mouth 2 upside down, it is pushed by the valve opening protrusion 4 to open the valve mechanism 6 and supply oil.

8 is a sensing lever, -@8a is inserted into the lower side of the oil tank 5, and the other end is the oil receiver, which is connected to the support shaft 1 of the support plate 9 attached to the pan 1.
It is rotatably supported by 0.

Reference numeral 11 denotes a display lever attached to the sensing lever, and a thin spring plate is used in the vertical direction, and a display section 12 is attached to the tip of the lever.

Reference numeral 14 denotes an exterior part, in which a display window 15 is provided in a part corresponding to the display part 2, and inside thereof a guide part 16 that guides both sides of the display part 12 and a regulation part that regulates the vertical position. 17a and 17b are provided. 18 is a sensing spring;
The foot 18a is inserted through the support shaft 10 and the other foot 18b is mounted on the support plate 9 and the sensing lever 8, respectively.
The biasing force is set in a direction to lift the fuel tank 5 when the amount of remaining oil in the fuel tank 5 becomes low.

In the above configuration, when the oil tank 5 is filled with oil to its full capacity, the cap 7 is closed, and the oil receiver is inserted upside down into the oil tank receiver 3 of the pan 1, the valve opening protrusion 4 pushes the valve mechanism 6 and opens it.
The oil pan is filled with oil in the pan 1.

At this time, the end 8a of the sensing lever 8 is pushed by the fuel tank 5 and lowered to the position shown by the solid line. The sensing lever 8 is a support shaft 10
Since the display lever 11 is pivotally supported by the display lever 11, the display lever 11 rises. At this time, the display section 12 attached to the tip of the sensing lever 8 is guided by the guide section 16 and rises without touching left and right, and hits the upper restriction section 17a and stops at a fixed position, and the display section 13
The display 13a indicating that there is a large amount of residual oil becomes accurately visible from the display window 15. Further, as the oil in the pan 1 is consumed, the oil in the oil pan gradually flows out from the oil tank 5, and its weight becomes lighter. When the set weight is eventually reached, the biasing force of the sensing spring 8 prevails and the fuel tank 5 is lifted up via the sensing lever 8.

At the same time, the display section 12 is guided by the guide section 16 and lowered, and stops in contact with the lower regulating section 17b. At this time, the empty amount display 13b of the display section 12 can be accurately seen through the display window 15, indicating that the amount of remaining oil in the fuel tank 5 is small.

Effects of the Invention As is clear from the description of the embodiments, the present invention has the display section 12.
The guide part 16 and the vertical regulation parts 17a and 17 of the exterior part 14
The movement (range is regulated by b), so the display window 15
The display does not fall off the screen, improving display accuracy, and at the same time, the display unit can be small, saving space. In addition, since the display lever 11 is constructed using a thin plate of spring material vertically, it can easily bend to accommodate slight positional misalignment between the exterior part 14 and the display part 12 in the left-right direction, resulting in less frictional resistance. It slides and can be expected to operate smoothly, and since it is difficult to bend in the direction of rotation, it does not impair display accuracy.

Further, since the display lever 11 is not easily deformed, it is easy to handle, and since the display lever 11 is moved by a vertical plate, the space around the display lever 11 can be greatly saved, and it can be easily combined with other mechanisms.
