Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to a gas valve suitable for ultra-thin stoves. Background Technology

[0002] Cooktops on the market are generally either built-in or countertop. Built-in cooktops require a suitable opening to be made in the cooktop before installation. While built-in cooktops save space, they also present a series of issues such as safety, cleaning, replacement, and how they match the cabinetry. Countertop cooktops, on the other hand, can be placed flat on the countertop, with the cooktop body flush against the surface, making them aesthetically pleasing, easy to move and clean.

[0003] For example, patent CN209484665U discloses a household gas ultra-thin stove, which includes an ultra-thin panel. An ultra-thin switch valve assembly is provided at the bottom of the ultra-thin panel. The ultra-thin switch valve assembly includes a valve body. The height of the valve body is similar to the height of the ultra-thin panel. A rotating shaft is connected to the valve body. A knob switch is provided at one end of the rotating shaft that passes through the ultra-thin panel. An ultra-thin burner assembly is also provided on the ultra-thin panel. The ultra-thin burner assembly includes a base. The height of the base is similar to the height of the ultra-thin panel. A gas distribution plate is provided on the base. An outer ring cover and an inner ring cover are provided on the gas distribution plate.

[0004] As can be seen from the above-mentioned prior art, the height of the valve body will affect the height of the panel. In order to minimize the thickness of the panel and make the stove very thin, occupy little space, have a low center of gravity, and be suitable for use on the stovetop in various households without the need for drilling holes, this application is dedicated to developing a valve body that can be used on ultra-thin stoves. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a gas valve suitable for ultra-thin stoves, which can reduce the thickness of the gas valve, thereby reducing the thickness of the ultra-thin stove.

[0006] The technical solution adopted by this utility model to solve the problem is: a gas valve suitable for ultra-thin stoves, including a valve body, a first gas outlet pipe provided at the front end of the valve body, a gas inlet pipe provided at the rear end of the valve body, a valve core cavity and a gas inlet groove provided around the valve core cavity provided in the valve body, the gas inlet groove connecting the gas inlet pipe and the valve core cavity, the valve core cavity connecting the first gas outlet pipe, and a valve core assembly provided in the valve core cavity.

[0007] As a further improvement to the above technical solution, the valve body also includes a first air inlet channel connecting the first air outlet pipe and the valve core cavity, wherein the axis of the first air inlet channel is perpendicular to the axis of the first air outlet pipe.

[0008] As a further improvement to the above technical solution, the valve body also includes a secondary air intake channel connecting the first air intake channel and the valve core cavity, and a threaded cavity perpendicular to and connected to the secondary air intake channel. An adjusting screw is dynamically sealed in the threaded cavity, and the adjusting screw is used to adjust the air intake volume entering the first air intake channel through the secondary air intake channel.

[0009] As a further improvement to the above technical solution, a second air outlet pipe is also included, which is arranged in the same direction as the first air outlet pipe. The valve core cavity includes an upper-opening receiving cavity and an installation cavity arranged in the same direction as the first air outlet pipe. The valve core cavity also includes an air outlet channel communicating with the receiving cavity and the installation cavity. The air inlet groove is connected to the installation cavity. A second air inlet channel is connected between the second air outlet pipe and the receiving cavity. The receiving cavity is connected to the first air inlet channel, the second air inlet channel, and the auxiliary air inlet channel. The valve core assembly is disposed in the receiving cavity, and a solenoid valve assembly is disposed in the installation cavity. The solenoid valve assembly is used to block the air outlet channel.

[0010] As a further improvement to the above technical solution, the valve core assembly includes a valve stem and a valve core. The valve core is disposed within a receiving cavity and has through holes communicating with a first air intake channel, a second air intake channel, and a secondary air intake channel, respectively.

A transmission assembly is disposed below the valve core and is drively connected to the solenoid valve assembly.

[0011] As a further improvement to the above technical solution, the transmission assembly includes a mounting base and a lever. The mounting base is fixedly disposed at the bottom of the receiving cavity, and the lever is rotatably connected to the mounting base. When the first push rod moves downward, the first push rod will push the lever downward, causing the lever to rotate relative to the mounting base and thus abut against the solenoid valve assembly.

[0012] As a further improvement to the above technical solution, the output end of the solenoid valve assembly is connected to a second push rod, and a piston is sleeved on the second push rod. The piston blocks the air outlet channel, and the end of the second push rod extends into the receiving cavity. A second spring is sleeved on the second push rod, and the second spring is located between the solenoid valve assembly and the piston. When the first push rod moves downward, the first push rod will push the lever downward, causing the lever to rotate relative to the mounting base and thus abut against the second push rod.

[0013] As a further improvement to the above technical solution, a micro switch is provided on the outer wall of the valve body, and a drive plate is sleeved on the valve stem. The drive plate includes an outwardly extending drive part, which is located on top of the micro switch.

[0014] As a further improvement to the above technical solution, the axes of the first air outlet pipe, the second air outlet pipe, the air inlet pipe, and the air inlet slot are all located at the same height.

[0015] The beneficial effects of this utility model are: the gas valve has an air inlet groove surrounding the valve core cavity, and the first gas outlet pipe and the gas inlet pipe are arranged opposite each other. The overall structure of the gas valve is compact, which can reduce the overall height of the valve body, thereby reducing the overall height of the gas stove, and is suitable for ultra-thin stoves.

[0033] Reference Figures 1 to 11A gas valve suitable for ultra-thin stoves includes a valve body 1, a first gas outlet pipe 11 provided at the front end of the valve body 1, a gas inlet pipe 12 provided at the rear end of the valve body 1, a valve core cavity 2 and a gas inlet groove 13 provided around the valve core cavity 2 inside the valve body 1, the gas inlet groove 13 connecting the gas inlet pipe 12 and the valve core cavity 2, the valve core cavity 2 connecting the first gas outlet pipe 11, and a valve core assembly 3 provided inside the valve core cavity 2.

[0034] The gas valve has an air inlet groove 13 surrounding the valve core cavity 2, and the first gas outlet pipe 11 and the air inlet pipe 12 are arranged opposite to each other. The gas valve has a compact overall structure, which can reduce the overall height of the valve body 1, thereby reducing the overall height of the gas stove, and is suitable for ultra-thin stoves.

[0035] In a preferred embodiment, the valve body 1 further includes a first air inlet channel 14 that connects the first air outlet pipe 11 and the valve core cavity 2, and the axis of the first air inlet channel 14 is perpendicular to the axis of the first air outlet pipe 11.

[0036] In a preferred embodiment, the valve body 1 further includes a secondary air intake channel 15 that connects the first air intake channel 14 and the valve core 32 cavity 2, and a threaded cavity 16 that is perpendicular to and connected to the secondary air intake channel 15. An adjusting screw 4 is dynamically sealed in the threaded cavity 16. The amount of air entering the first air intake channel 14 through the secondary air intake channel 15 can be adjusted by rotating the adjusting screw 4.

[0037] In a preferred embodiment, the system further includes a second air outlet pipe 17 arranged in the same direction as the first air outlet pipe 11. The valve core cavity 2 includes a receiving cavity 21 with an upper opening and an installation cavity 22 arranged in the same direction as the first air outlet pipe 11. The valve core cavity 2 also includes an air outlet channel 23 connecting the receiving cavity 21 and the installation cavity 22. An air inlet groove 13 is connected to the installation cavity 22. A second air inlet channel 18 is connected between the second air outlet pipe 17 and the receiving cavity 21. The receiving cavity 21 is connected to the first air inlet channel 14, the second air inlet channel 18, and the auxiliary air inlet channel 15, respectively. The valve core assembly 3 is disposed in the receiving cavity 21, and a solenoid valve assembly 5 is disposed in the installation cavity 22. The solenoid valve assembly 5 is used to block the air outlet channel 23.

[0038] In a preferred embodiment, the valve core assembly 3 includes a valve stem 31 and a valve core 32. The valve core 32 is disposed in the receiving cavity 21. The valve core 32 is provided with through holes 321 that communicate with the first air intake channel 14, the second air intake channel 18 and the auxiliary air intake channel 15 respectively. The valve stem 31 is movably disposed on the top of the valve core 32. The bottom of the valve stem 31 is connected to a first push rod 33. The lower part of the first push rod 33 passes through the valve core 32 and is dynamically sealed to the valve core 32. The upper part of the first push rod 33 is sleeved with a first spring 34, which is located between the valve stem 31 and the valve core 32.

[0039] A transmission assembly 6 is provided below the valve core 32, and the transmission assembly 6 is connected to the solenoid valve assembly 5.

[0040] In use, the valve stem 31 is pressed down, which causes the first push rod 33 to abut against the transmission assembly 6, so that the transmission assembly 6 drives the solenoid valve assembly 5 to open the air outlet channel 23, thereby connecting the receiving cavity 21 and the mounting cavity 22.

[0041] In a preferred embodiment, the transmission assembly 6 includes a mounting base 61 and a lever 62. The mounting base 61 is fixedly disposed at the bottom of the receiving cavity 21, and the lever 62 is rotatably connected to the mounting base 61.

[0042] When the first push rod 33 moves downward, it pushes the lever 62 downward, causing the lever 62 to rotate relative to the mounting base 61 and come into contact with the solenoid valve assembly 5, thereby opening the air outlet passage 23 of the solenoid valve assembly 5.

[0043] In a preferred embodiment, the output end of the solenoid valve assembly 5 is connected to a second push rod 51, a piston 52 is sleeved on the second push rod 51, the piston 52 blocks the air outlet passage 23, the end of the second push rod 51 extends into the receiving cavity 21, and a second spring 53 is sleeved on the second push rod 51, the second spring 53 is located between the solenoid valve assembly 5 and the piston 52.

[0044] When the first push rod 33 moves downward, it pushes the lever 62 downward, causing the lever 62 to rotate relative to the mounting base 61 and come into contact with the second push rod 51. This causes the lever 62 to rotate and come into contact with the second push rod 51, and the second push rod 51 to move, causing the piston 52 to disengage from the gas outlet passage 23. At this time, the first spring 34 will reset the first push rod 33, and the solenoid valve assembly 5 will open, preventing the second push rod 51 from resetting. Rotating the valve rod 31 can drive the valve core 32 to rotate, thereby regulating the amount of gas passing through the through hole 321.

[0045] When the valve stem 31 is rotated and the air outlet is closed, the solenoid valve assembly 5 will close. Under the influence of the second spring 53, the second push rod 51 will reset, thereby causing the piston 52 to block the air outlet passage 23.

[0046] In a preferred embodiment, a micro switch 7 is provided on the outer wall of the valve body 1, and a drive plate 35 is sleeved on the valve stem 31. The drive plate 35 includes an outwardly extending drive part 351, which is located on top of the micro switch 7.

[0047] By pressing down the valve stem 31, the drive plate 35 can be moved downward, causing the drive unit 351 to press down the micro switch 11, thereby turning on the micro switch 11.

[0048] In a preferred embodiment, the axes of the first air outlet pipe 11, the second air outlet pipe 17, the air inlet pipe 12, and the air inlet slot 13 are all located at the same height.

[0049] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
