Description

Technical Field

[0001] The utility model belongs to the technical field of gas stove accessories, and in particular relates to a synchronous ultra-thin plug valve without a rear cover. Background Art

[0002] Gas stoves are usually controlled by plug valves to open and close. Embedded gas stoves are currently more commonly used. Embedded means that the cabinet countertop is made into a "concave" shape, which can be embedded in the gas stove. The gas stove cabinet and the cabinet countertop are in the same plane. Embedded gas stoves are beautiful, space-saving, and easy to clean, making the kitchen more harmonious and complete, and more convenient for matching with other products. Therefore, they are loved by consumers.

[0003] The solenoid valve currently used requires pressing down the valve stem, which drives the valve needle to push the lever, and the lever pushes open the solenoid valve. The air intake channel is then opened by rotating the valve stem. This results in a large number of mechanical parts required for the entire valve body, and the valve body needs to be provided with a back cover to form a cavity to accommodate the lever, which in turn causes the plug valve to be too thick, making it impossible to produce an ultra-thin household gas stove, reducing the user experience when using it.

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figure 1-7 As shown, the utility model provides a synchronous ultra-thin plug valve without a rear cover, comprising:

[0036] The valve body 100 has a first air inlet passage 110, a second air inlet passage 120, a primary fire outlet passage 130, and a secondary fire outlet passage 140;

[0037] A self-priming solenoid valve 150 is disposed in the valve body 100, and the self-priming solenoid valve 150 is used to open or cut off the communication between the first air intake passage 110 and the second air intake passage 120;

[0038] The valve core 160 is disposed in the valve body 100 , and the communication between the second air inlet passage 120 and the primary and secondary fire outlet passages 130 and 140 is opened or cut off by rotating the valve core 160 .

[0039] It should be noted that the solenoid valve in this embodiment is a self-priming solenoid valve 150, which can open or cut off the connection between the first air intake channel 110 and the second air intake channel 120 by simply turning on or off the power, without requiring additional mechanical components to open the solenoid valve, such as a valve needle or a lever in the prior art, thereby saving materials and reducing costs.

[0040] As such, the valve body 100 does not need to be provided with an additional back cover on its bottom surface to accommodate additional mechanical components, thereby reducing the thickness of the entire plug valve, achieving the purpose of an ultra-thin plug valve, and also reducing the possibility of air leakage.

[0041] This ultra-thin plug valve is suitable for installation in environments with limited space or high requirements for aesthetics, such as the interior of kitchen cabinets. Traditional gas equipment installation often requires holes to be opened in the cabinet to accommodate and connect valves and pipes, but the emergence of this ultra-thin plug valve can achieve the purpose of not opening holes in the cabinet, greatly improving the convenience of installation and the overall aesthetics of the kitchen;

[0042] This design not only reduces the changes to the cabinet structure during the installation process, reducing installation costs and time, but also avoids problems such as cabinet waterproofing and insect-proofing that may be caused by opening holes, which is conducive to maintaining the integrity of the cabinet and extending its service life.

[0043] Preferably, the self-priming solenoid valve 150 is disposed in a solenoid valve channel 151 formed in the valve body 100 , and the first air intake channel 110 is connected to the second air intake channel 120 through the solenoid valve channel 151 .

[0044] Specifically, when the self-priming solenoid valve 150 is not energized, its piston closes the solenoid valve channel air outlet 152, and at this time, the first air intake channel 110 and the second air intake channel 120 are not connected;

[0045] When the self-priming solenoid valve 150 is energized, its piston moves upward and opens the solenoid valve channel air outlet 152 . At this time, the first air inlet channel 110 is connected to the second air inlet channel 120 , and the gas enters the valve body 100 .

[0046] Preferably, the main fire outlet channel 130 and the secondary fire outlet channel 140 are arranged in parallel. As the valve core 160 rotates, the main fire outlet channel 130, the secondary fire outlet channel 140 and the second air intake channel 120 are connected or closed to achieve the purpose of synchronously opening and closing the fire.

[0047] Preferably, a valve core connecting channel 161 is provided on the surface of the valve core 160, and the axis of the valve core 160 is set as a solid so that the valve core connecting channel 161 is set in an arc-shaped structure, thereby meeting the requirements of the main fire outlet channel 130 and the secondary fire outlet channel 140 for simultaneously emitting fire, turning off the fire, and keeping the fire of the stove.

[0048] Specifically, when the valve core 160 is at the 0° position, a sealing angle is formed between the second air inlet channel 120 and the valve core connecting channel 161 and the two are not connected. At this time, the gas cannot enter the main fire outlet channel 130 and the secondary fire outlet channel 140, and the stove is in the off state.

[0049] When the valve core 160 rotates between 0°-90°, the valve body 100 is in the front-end state, the self-priming solenoid valve 150 is opened, and the second air inlet channel 120 is connected with the first air inlet channel 110. At this time, the gas passes through the first air inlet channel 110 and the solenoid valve channel outlet 152 in sequence and enters the second air inlet channel 120.

[0050] When the valve core connecting channel 161 is not connected with the second air intake channel 120, the valve core connecting channel 161 is pre-connected with the main fire channel 130 and the secondary fire channel 140. Thus, once the valve core connecting channel 161 is connected with the second air intake channel 120, the main fire channel 130 and the secondary fire channel 140 can achieve the purpose of synchronous ignition.

[0051] Furthermore, when the valve core 160 rotates after 90°, the valve body 100 is in an open rear state. When the valve core 160 rotates to a preset angle, the valve core connecting channel 161 and the main fire outlet channel 130 are closed. At the same time, the valve core connecting channel 161 and the secondary fire outlet channel 140 remain connected to keep the stove in a fire preservation state.

[0052] Preferably, it also includes a valve cover 170 and a valve stem 180. The valve cover 170 is connected to the valve body 100. The valve stem 180 passes through the valve cover 170 and is connected to the valve core 160. The valve core 160 is driven to rotate by the valve stem 180 to realize the switching control of the air flow channel.

[0053] Among them, a spring cavity is provided at one end of the valve core 160 for connecting with the valve stem 180, and a spring 190 is installed in the spring cavity. The two ends of the spring 190 are respectively in contact with the valve core 160 and the valve stem 180. On the one hand, the spring 190 plays a role in lifting the valve stem 180. After the valve stem 180 is pressed down to open the child lock, the valve stem 180 can be rotated. On the other hand, the spring 190 can also allow the valve core 160 to maintain a conical surface fit and sealing state to prevent air leakage.

[0054] The technical means disclosed in the scheme of the utility model are not limited to the technical means disclosed by the above technical means, but also include technical solutions composed of any combination of the above technical features. The above is a specific implementation method of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.

If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
