DETAILED DESCRIPTION

[0027] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figures 1 to 5 The switch valve 100 provided by the embodiment of the present utility model includes the switch valve 100, a transparent knob seat 20, a light board 30, a rotating shaft 41 and a lighting micro switch 50.

[0032] Among them, see Figures 1 to 4 The valve body 10 is provided with an air inlet channel 11 and an air outlet channel 12; the transparent knob seat 20 is provided above the valve body 10; the light board 30 is provided between the valve body 10 and the transparent knob seat 20; the rotating shaft 41 is movably arranged relative to the valve body 10, and is passed through the transparent knob seat 20 and the light board 30; the lighting micro switch 50 is installed on the valve body 10 and is electrically connected to the light board 30, and is used to achieve electrical conduction with the light board 30 when the rotating shaft 41 is pressed.

[0033] The above-mentioned switch valve 100 can simultaneously trigger the lighting microswitch 50 when the rotating shaft 41 is pressed or rotated relative to the valve body 10 to open the air inlet channel 11 of the valve body 10, thereby realizing the power-on of the light panel 30. At the same time, since the light panel 30 is arranged between the valve body 10 and the transparent knob seat 20, the light emitted by the light panel 30 can pass through the transparent knob seat 20, making it convenient for users to check the usage status of the gas appliance.

[0034] As will be understood, the valve body 10 is provided with an air inlet channel 11, which is used to communicate with a gas cylinder to input gas into the valve body 10. The valve body 10 is provided with an air outlet channel 12, which is used to output gas to a gas appliance for ignition and heating. The configuration of the air inlet channel 11 and the air outlet channel 12 can be conventionally configured and will not be described in detail here. Furthermore, the valve body 10 can also be provided with a solenoid valve 13 to facilitate closing or opening the channel connecting the air inlet channel 11 and the valve body 10. When opened, this allows for stable gas input into the valve body 10.

[0035] Among them, see Figures 1 to 5 The valve body 10 of this embodiment includes a main body 14 and a cover 15. The main body 14 is provided with an air inlet channel 11, an air outlet channel 12, and a solenoid valve 13. The cover 15 is disposed above the main body 14 and includes a shielding portion 151 and a sleeve portion 152 disposed in the center of the shielding portion 151. The shielding portion 151 covers the main body 14 and the lighting microswitch 50. The sleeve portion 152 sleeves around the rotating shaft 41. The transparent knob seat 20 and the light board 30 sleeve around the sleeve portion 152. Thus, by extending the sleeve portion 152 from the cover 15, the transparent knob seat 20 is sleeved around the sleeve portion 152, thereby achieving installation of the transparent knob seat 20. At the same time, the light board 30 is sandwiched between the shielding portion 151 and the transparent knob seat 20, thereby also achieving installation of the light board 30. The shielding portion 151 forms a receiving space for accommodating a portion of the main body 14.

[0036] It can be understood that the switch valve 100 of this embodiment also includes structures such as a plug 44, a push rod 42 and an elastic member 43. The plug 44, the push rod 42 and the elastic member 43 are all arranged in the valve body 10. The rotating shaft 41 extends into the main body 14 and is clamped on the plug 44, so that the rotation of the rotating shaft 41 can drive the plug 44 to rotate to achieve the adjustment of the gas volume of the air outlet channel 12; at the same time, when the rotating shaft 41 is pressed down, pressure is applied to the push rod 42, and the push rod 42 pushes the solenoid valve 13 open, and at the same time pressure is applied to the elastic member 43 to compress the elastic member 43, and the elastic member 43 drives the rotating shaft 41 to restore its original position.

[0037] The transparent knob seat 20 can be made of transparent plastic or silicone, so that the light emitted by the light board 30 can pass through the transparent knob seat 20 .

[0038] Further, see Figures 1 to 3 The transparent knob seat 20 includes a blocking portion 21 and a supporting portion 22. The blocking portion 21 blocks the light board 30. The supporting portion 22 is provided at the bottom of the blocking portion 21 and abuts against the light board 30. In this way, through the setting of the supporting portion 22, when the rotating shaft 41 is subjected to the pressing force applied by the knob, the pressure is transmitted to the light board 30 through the setting of the supporting portion 22. The light board 30 transmits the pressing force to the cover body 15 of the valve body 10, thereby avoiding the transparent knob seat 20 being pressed toward the valve body 10 and shifting under the pressure of the knob. The supporting portion 22 achieves a limiting effect.

[0039] It should be noted that in order to ensure the installation strength of the entire transparent knob seat 20 on the sleeve portion 152 of the cover body 15, not only the blocking portion 21 is sleeved on the outer wall surface of the sleeve portion 152, but the supporting portion 22 is also sleeved on the outer wall surface of the sleeve portion 152.

[0040] Understandably, please refer to the diagram and Figure 5 Since a knob needs to be installed on the rotating shaft 41 and it is convenient to make the lamp board 30 waterproof and dustproof, the blocking part 21 includes an annular ring 211 and a shielding plate 212. The annular ring 211 and the supporting part 22 are arranged on opposite sides of the shielding plate 212. A receiving groove 213 is formed between the annular ring 211 and the shielding plate 212. The receiving groove 213 is used to receive the knob, that is, a receiving groove 213 is formed on the transparent knob seat 20. The receiving groove 213 can collect dust and moisture to protect the lamp board 30. At the same time, the knob is set in the receiving groove 213. The light emitted by the lamp board 30 located below the transparent knob seat 20 can pass through the transparent knob seat 20 to avoid being blocked by the knob, thereby ensuring the brightness of light seen by the user, so as to quickly judge the usage status of the gas appliance according to the brightness of the light.

[0041] Furthermore, when the sleeve portion 152 of the cover body 15 is set, the sleeve portion 152 protrudes from the baffle 212. Since a knob needs to be installed on the rotating shaft 41, the knob is made of metal and has a certain weight. At the same time, the knob will apply pressing force to the rotating shaft 41. By setting a higher height for the sleeve portion 152, the pressure from the knob can be shared, so as to reduce the pressure applied by the knob to parts such as the rotating shaft 41, the plug 44 and the push rod 42, thereby ensuring the service life of the entire switch valve 100.

[0042] It is understandable that the height of the portion of the sleeve portion 152 protruding from the shielding plate 212 needs to be smaller than the height of the annular ring 211 to ensure that there is sufficient contact area between the knob and the rotating shaft 41 .

[0043] See also Figure 2 When the lamp panel 30 is installed, the shielding portion 151 of the cover body 15 is bolted to the main body 14, and the shielding portion 151 of the lamp panel 30 and the cover body 15 is also bolted. Furthermore, since the transparent knob seat 20 is sleeved outside the sleeve portion 152 of the cover body 15, the lamp panel 30 is clamped between the shielding portion 151 and the transparent knob seat 20, thereby achieving the fixation of the transparent knob seat 20 and the lamp panel 30. The rotating shaft 41 rotates relative to the cover body 15, and the transparent knob seat 20 and the lamp panel 30 are in a fixed state. At the same time, the shielding portion 151 of the cover body 15 and the main body 14, as well as the lamp panel 30 and the shielding portion 151 of the cover body 15 are bolted to facilitate the installation and maintenance after disassembly of the entire valve body 10.

[0044] It should be noted that, since the lamp board 30 needs to emit light, a lamp bead 31 is provided on the lamp board 30; at the same time, the lamp board 30 needs to be electrically connected to the controller of the main unit of the gas appliance, so a connecting plug 32 electrically connected to the controller is provided on the lamp board 30, so that after the connecting plug 32 is plugged into the wiring harness, electrical conduction with the controller is conveniently achieved.

[0045] Furthermore, since the rotating shaft 41 needs to trigger ignition when pressed, the switch valve 100 also includes an ignition micro switch 60, and the valve body 10 also includes a mounting bracket 16 provided between the valve body 10 and the cover body 15. The mounting bracket 16 is used to install the ignition micro switch 60. The ignition micro switch 60 is provided with an ignition spring 61. In this way, when the knob presses the valve body 10, the pressing piece 17 provided in the cover body 15 moves downward, and the pressing piece 17 contacts the ignition spring 61, triggering the ignition micro switch 60. 0, the ignition microswitch 60 and the igniter are electrically connected, thereby realizing the ignition function. Furthermore, the solenoid valve 13 is pushed open by the push rod 42. When the igniter ignites, heat is provided to the thermocouple, and the thermocouple forms an electric potential difference, thereby transmitting an electrical signal to the solenoid valve 13, so that the solenoid valve 13 is in a stable attracted state and continuously opens the communication port between the intake passage 11 and the cock 44. Furthermore, the ignition microswitch 60 is installed by providing a mounting bracket 16 between the cover 15 and the main body 14. It can be understood that the mounting bracket 16 is fixed relative to the valve body 10 to ensure that the ignition microswitch 60 is in a fixed state.

[0046] The above-mentioned switch valve 100 is provided with the cover body 15 including a shielding portion 151 and a sleeve portion 152 provided in the central area of ​​the shielding portion 151, and the transparent knob seat 20 and the light board 30 are sleeved outside the sleeve portion 152 to achieve the installation of the transparent knob seat 20. At the same time, the light board 30 is sandwiched between the shielding portion 151 and the transparent knob seat 20, and the installation of the light board 30 is also achieved. By providing the transparent knob seat 20 with a blocking portion 21 and a supporting portion 22, the supporting portion 22 and the light board 30 are abutted against each other, so as to prevent the transparent knob seat 20 from being pressed toward the valve body 10 when the knob is pressed. By setting a receiving groove 213 in the blocking portion 21, the light emitted by the light board 30 located below the transparent knob seat 20 can pass through the transparent knob seat 20 to avoid being blocked by the knob, thereby ensuring the brightness of the light seen by the user. At the same time, the receiving groove 213 can collect dust and moisture to protect the light board 30; by setting the sleeve portion 152 to protrude from the shielding plate 212, the pressure from the knob can be shared to reduce the pressure applied by the knob to the parts such as the rotating shaft 41, the plug 44 and the push rod 42, thereby ensuring the service life of the entire switch valve 100
