Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a valve body shell of a gas valve. Background Art

[0002] The valve body shell of the existing gas valve for a portable stove includes the valve body shell of the portable stove gas valve, the air inlet and the switch device are arranged on opposite sides of the valve body, and the air inlet and the gas supply tank connection device are arranged on the same axis as the switch, resulting in a relatively large thickness of the entire valve body. For example, the Chinese Utility Model Specification (Authorization Announcement No.: CN201487327U) discloses a portable stove gas valve for a portable stove. Figure 1 As shown, it comprises a valve body 1, the rear end of which has an air inlet 2 connected to a gas supply tank. A decompression chamber 3, communicating with the air inlet 2, is located at the upper end of the valve body 1. A rotary adjustment lever, a combination of a knob and a switch component 65, is located at the front end of the valve body 1. Rotation of the switch component 65 controls the opening and closing of the air outlet 4. Gas supplied from the gas supply tank enters the decompression chamber 3 through the air inlet 2 for decompression. Under the control of the switch component 65 at the front end of the valve body, the decompressed gas is discharged from the decompression chamber 3 and into the air outlet duct, where it is then discharged from the air outlet 4 to supply the combustion mechanism. In this structure, the rotary adjustment lever, a combination of the switch component 65 and the knob, is relatively long. Because the rotary adjustment lever must be located at the front end of the valve body 1 and coaxial with the air inlet 2, i.e., the switch component 65 and the air inlet 2 are coaxial, the front-to-back spans of the valve body 1 are relatively large, resulting in a thicker valve body shell.

[0003] In recent years, with the rise of outdoor sports, portable outdoor equipment has flourished. In order to adapt to the trend and be portable, outdoor portable cassette stoves have gradually become miniaturized. However, due to the thickness of the valve body shell of the cassette stove gas valve, miniaturized cassette stoves will have the following problems: Figure 2 The awkwardness shown is that due to the thickness of the valve body shell of the gas valve of the cassette cooker, the end of the gas supply tank has to be exposed outside the gas tank compartment. This design is really helpless. In the event of an explosion in a cassette cooker with an exposed gas supply tank, the gas supply tank is not restrained and may hit the user, or cause a large-scale gas leak, leading to a more serious accident. The tail of the gas supply tank is exposed, and when the cookware is in use, the heat will radiate to the gas supply tank, causing the gas supply tank to overheat, posing a safety hazard. The exposed gas supply tank is easily touched during use, causing leakage or the gas supply tank to fall off. The exposed gas supply tank is easily blocked by other objects during use, causing the cassette cooker's overpressure safety device to fail and the gas supply tank to be unable to be effectively ejected.

[0004] Therefore, the problem of the exposed setting of the gas supply tank of the small cassette stove needs to be solved urgently. Utility Model Content

[0005] The purpose of this utility model is to provide a valve body shell for a gas valve. The gas valve of this utility model overcomes the defects of the prior art gas valve body being too thick to be adapted to small outdoor stoves, resulting in the gas supply tank being exposed. To achieve the above purpose, the technical solution of this utility model is:

[0006] A valve body shell of a gas valve is provided with an air inlet component mounting port connected to a gas supply tank, an air inlet air duct, a decompression chamber, an air outlet air duct and an air outlet component mounting port for supplying gas to a combustion mechanism;

[0007] The air inlet component installation port is the opening of the air inlet duct, which is connected to the decompression chamber. The air outlet component installation port is the opening of the air outlet duct, which is connected to the decompression chamber.

[0008] A mounting groove for installing a control component, a transmission component and a switch component for adjusting the air output is provided on the side opposite to the air inlet component mounting port, and a switch component mounting portion is provided on one side of the mounting groove, and the switch component mounting portion is provided on the side deviating from the axis of the air inlet component mounting port; the switch component mounting portion is provided on the channel connecting the decompression chamber and the air outlet duct.

[0009] The switch component mounting portion is a groove, the bottom of the groove is provided with a first through hole communicating with the decompression chamber, and the side wall of the groove is provided with a second through hole communicating with the air outlet passage.

[0010] The groove is in a frustum shape, and the upper bottom surface is larger than the lower bottom surface.

[0011] A sealing sleeve adapted to the groove is provided, a fourth through hole is provided at the bottom of the sealing sleeve, a third through hole is provided at the side wall of the sealing sleeve, the fourth through hole is communicated with the first through hole, and the third through hole is communicated with the second through hole.

[0012] The sealing sleeve is in a frustum shape and is matched with the groove.

[0013] A clamping groove is provided on the side wall of the groove, and a clamping strip is provided on the outer wall of the sealing sleeve. The clamping strip of the sealing sleeve is matched with the clamping groove of the groove.

[0014] A cover body is also provided to cover the installation groove.

[0015] A decompression hatch cover is also provided to cover the decompression chamber.

[0016] The decompression chamber is arranged on the same side of the switch component mounting portion.

[0017] The air outlet is arranged on the same side of the switch component installation portion.

[0018] The advantages of the present invention are as follows: 1. The switch component mounting portion is arranged beside the axis of the air inlet component mounting opening, which fully utilizes the space in the middle portion of the valve body, thereby reducing the thickness of the valve body and utilizing the space of the valve body. 2. Because the switch component mounting portion is arranged beside the axis of the air inlet component mounting opening, the gas outlet component mounting opening can also be designed based on the position of the switch component mounting portion. Designing it on one side of the switch component mounting portion shortens the distance between the gas outlet and the combustion device, thereby making the gas outlet response speed of the gas valve faster. 3. The transmission component can be made thinner, and the depth of the mounting groove can be adjusted according to the thickness of the transmission component, effectively reducing the thickness of the front and rear ends of the valve body shell. 4. The decompression chamber is arranged on one side of the switch component mounting portion, thereby reducing the volume of the valve body. 5. The thickness and volume of the valve body shell are reduced. The thickness and volume of the gas valve body of the present invention are thinner and smaller than those of the prior art, thereby miniaturizing the gas valve. The gas supply tank of a small portable stove is no longer exposed, eliminating safety hazards and making the portable stove more portable and safer to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings, which are for illustrative purposes only and are not to be construed as limiting the present invention.

[0028] To more concisely illustrate this embodiment, some components well known to those skilled in the art but not relevant to the main content of this invention may be omitted from the drawings or descriptions. In addition, for ease of description, some components may be omitted, enlarged, or reduced in size in the drawings, but they do not represent the dimensions or entire structure of the actual product.

[0029] The utility model discloses a valve body shell of a gas valve, such as Figure 3-6 As shown, an air inlet component mounting port 21 connected to a gas supply tank, an air inlet duct, a decompression chamber 31, an air outlet duct, and an air outlet component mounting port 41 for supplying air to the combustion mechanism are provided;

[0030] The air inlet component mounting port 21 is the opening of the air inlet duct, which is in communication with the decompression chamber 31. The air outlet component mounting port 41 is the opening of the air outlet duct, which is in communication with the decompression chamber 31.

[0031] like Figure 7 As shown, a mounting groove 5 for mounting the control component 8, the transmission component 9 and the switch component 65 for adjusting the air output is provided on the opposite side of the air intake component mounting port 21, that is, the mounting groove 5 and the air intake component mounting port 21 are distributed at the front and rear ends of the valve body shell.

[0032] A switch component mounting portion 6 is provided in the mounting groove 5 on one side of the axis of the air inlet component mounting port 21. The switch component mounting portion 6 is provided on the passage communicating with the decompression chamber 31 and the air outlet duct. The difference from the prior art is that the switch component mounting portion 6 is provided on the side deviating from the axis of the air inlet component mounting port 21. By applying the valve body shell of the utility model, the span of the front and rear ends of the valve body 1 can be reduced. Compared with the existing gas valve, the thickness of the valve body 1 is thinned. When applied to a small outdoor cassette stove, it can avoid the following problems: Figure 2 Gas supply tank shown exposed.

[0033] like Figure 3-5 As shown, the switch component mounting portion 6 is a groove 61, the bottom of the groove 61 is provided with a first through hole 62 that is connected to the decompression chamber 31, and the side wall of the groove 61 is provided with a second through hole 63 that is connected to the air outlet duct;

[0034] Preferably, the groove 61 is in a frustum shape, with the upper bottom surface being larger than the lower bottom surface.

[0035] Furthermore, if Figure 6As shown, a sealing sleeve 7 is provided to fit within the groove 61. A fourth through hole 72 is provided at the bottom of the sealing sleeve 7, and a third through hole 71 is provided on the sidewall of the sealing sleeve 7. The fourth through hole 72 is communicated with the first through hole 62, and the third through hole 71 is communicated with the second through hole 63. The sealing sleeve 7 can enhance the airtightness between the groove 61 and the switch component 65.

[0036] The sealing sleeve 7 is in a frustum shape and is matched with the groove 61 .

[0037] Furthermore, in order to ensure that the sealing sleeve 7 is installed stably and firmly, a clamping groove 64 is provided on the side wall of the groove 61 , and a clamping strip 73 is provided on the outer wall of the sealing sleeve 7 . The clamping strip 73 of the sealing sleeve 7 is adapted to the clamping groove 64 of the groove 61 .

[0038] Furthermore, a cover 10 is provided to cover the installation slot 5 , so as to cover the transmission component 9 and the switch component 65 in the installation slot 5 .

[0039] The decompression chamber 31 is disposed on the same side as the switch component mounting portion 6, shortening the distance between the bottom of the groove 61 and the decompression chamber 31 and reducing the volume of the valve body shell. The air outlet 4 can also be disposed on the same side as the switch component mounting portion 6. This arrangement shortens the distance between the decompression chamber 31 and the air outlet 4, improving ignition efficiency and speeding up the reaction.

[0040] A decompression chamber cover 11 is also provided to cover the decompression chamber 31 .

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the technical scope of the present invention.
