Description

Technical Field

[0001] The invention relates to the field of gas stoves, in particular to an electric valve body and a gas stove. Background Art

[0002] With the advancement of technology, the emergence of electronically controlled stoves has brought great convenience to people's cooking. People only need to press buttons to control the stove switch and the size of the fire. However, the core valve body of the existing electronically controlled stove uses multiple proportional valves to achieve the size of the fire, which is expensive, complex to control, and has a high failure rate. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide an electric valve body and a gas stove, aiming to provide a valve body suitable for an electronically controlled stove.

[0004] In order to achieve the above object, the present invention adopts the following scheme:

[0005] An electric valve body comprises a valve seat, a valve core, a driving motor and a solenoid valve, wherein the valve seat is provided with a valve core cavity, a solenoid valve cavity, an air inlet and at least one air outlet, the air inlet and the air outlet are connected via an air passage, the solenoid valve is arranged in the solenoid valve cavity, the valve core is arranged on the valve core cavity, the valve core cavity is connected to the air outlet, the driving motor drives the valve core to rotate, the driving motor directly or indirectly drives the solenoid valve to close, and the traditional solenoid valve and valve core structure are used, which can effectively ensure the air tightness and the safety of the product, and the driving motor drives the valve core to rotate while directly or indirectly The solenoid valve is driven to close, which changes the traditional starting method of the plug valve, which requires pressing and then turning the valve stem. In the present technical solution, the solenoid valve can be closed by simply turning the motor, and the airway in the valve body is opened. At the same time, the valve core is rotated to adjust the firepower, which provides a basis for electrically controlling the gas stove to start and stop and adjust the firepower. At the same time, the use of the traditional valve core structure is safe and reliable, and is not prone to air leakage. The original vertical setting structure of the valve core is changed on the valve seat, and the valve core is set horizontally, which changes the original vertical setting structure of the valve core, greatly reduces the height of the valve body, and forms an ultra-thin valve body.

[0006] In one or more embodiments, the drive motor drives the valve core to rotate via a gear, a pulley or a gear screw, and the rotating shaft of the drive motor and the valve core move at a set rotation ratio to control the rotation of the valve core through the drive motor, thereby enabling the user to start the stove with one click by controlling the speed of the drive motor and the rotation angle of the motor shaft.

[0007] In one or more embodiments, the valve core cavity is formed into a cone to match the valve core, and the large end of the valve core cavity is provided with an air inlet end, which is connected to the air channel.

[0008] In one or more embodiments, the valve core forms a conical valve core and cooperates with the valve core cavity. The valve core is provided with an air inlet hole that cooperates with the air inlet end. An air hole connected to the air outlet is provided on the conical surface of the valve core. The airway connects the large end of the valve core cavity and enters from the air inlet hole of the valve core. The valve core is pressed toward the small end of the valve core by the air pressure, so that the gap between the valve core and the valve core cavity becomes smaller, the sealing area is increased, the air tightness is improved, and the leakage caused by leakage in the center of the gas valve core is avoided.

[0009] In one or more embodiments, the valve core is horizontally arranged in the valve seat or tilted in the valve seat, and the valve core is changed from a traditional vertical setting to a horizontal setting or a tilted setting of the present technical solution, thereby reducing the height of the valve body and changing the setting of the airway. Since the ejector pin of the traditional valve body is arranged in the middle of the valve core, the airway of the valve body can only be connected to the lower end of the valve body. This causes the gas to lift the ejector rod when the valve body is on fire, and the gas leaks from the gap between the ejector rod and the valve core, resulting in fire leakage. The ejector pin structure is cancelled in the present technical solution, and the gas will not leak from the center of the valve core. At the same time, by setting the air outlet position of the airway, the gas presses the valve core toward the small end of the valve core, so that the valve core is tightly attached to the valve core cavity, increasing the sealing area and thus improving the air tightness, avoiding air leakage, and eliminating the problem of air leakage from the center of the valve core, solving a major problem of air leakage and fire leakage of the valve body.

[0010] In one or more embodiments, the drive motor is installed inside or outside the valve seat, the drive motor indirectly drives the valve core to rotate, or the valve core is connected to the motor shaft of the drive motor, and the valve core rotates with the motor shaft.

[0011] In one or more embodiments, a push rod and a shift rod are further provided, and a first shift block and a second shift block are provided at different angles of the shift rod. The second shift block drives the push rod to move in the direction of the solenoid valve so as to close the solenoid valve. The drive motor directly or indirectly drives the first shift block to move around the axis of the shift rod and thereby drives the second shift block to move.

[0012] In one or more embodiments, when the driving motor directly drives the first shift block to move, at least one first driving block is provided at the end of the motor shaft of the driving motor, and the first driving block rotates with the motor shaft of the driving motor to drive the first shift block to move; when the driving motor indirectly drives the first shift block to move, at least one second driving block is provided on the valve core, and the second driving block rotates with the valve core, and the second driving block drives the first shift block to move.

[0013] In one or more embodiments, a component for converting angular displacement or linear displacement into an electrical signal is disposed on the motor shaft or the valve core of the drive motor to record and send the angular displacement signal or linear displacement signal of the motor shaft or the valve core.

[0014] A gas stove comprises the electric valve body mentioned above.

[0015] Beneficial effects: The present invention provides an electric valve body and a gas stove, which follow the traditional solenoid valve and valve core structure, can effectively ensure the air tightness and product safety, and the driving motor drives the valve core to rotate while directly or indirectly driving the solenoid valve to close, which changes the traditional starting method of the plug valve that requires pressing and then rotating the valve stem. In the present technical solution, it is only necessary to rotate the motor to close the solenoid valve, open the airway in the valve body, and rotate the valve core to adjust the firepower, which provides a basis for electrically controlling the gas stove to start and stop and adjust the firepower. At the same time, the use of the traditional valve core structure is safe and reliable, and is not prone to air leakage. The original vertical setting structure of the valve core is changed on the valve seat, and the valve core is set horizontally, which changes the original vertical setting structure of the valve core, greatly reduces the height of the valve body to form an ultra-thin valve body.

[0023] The present application scheme is further described as follows in conjunction with the accompanying drawings:

[0024] Example:

[0025] See attached Figure 1-5, an electric valve body, comprising a valve seat 1, a valve core 2, a driving motor 3 and a solenoid valve 4, wherein the valve seat 1 is provided with a valve core cavity 15, a solenoid valve cavity 14, an air inlet 11 and at least one air outlet 12, wherein the air inlet 11 and the air outlet 12 are connected via an air passage 13, the solenoid valve 4 is arranged in the solenoid valve cavity 14, the valve core 2 is arranged on the valve core cavity 15, the valve core cavity 15 is connected to the air outlet 12 and the air passage 13, the driving motor 3 drives the valve core 2 to rotate, the driving motor 3 directly or indirectly drives the solenoid valve 4 to close, and the conventional solenoid valve 4 and valve core 2 structure are used, which can effectively ensure the air tightness and the safety of the product, and the driving motor 3 drives the valve core 2 to rotate while directly or indirectly The solenoid valve 4 is driven to attract, which changes the traditional starting method of the plug valve, which requires first pressing and then turning the valve stem. In the present technical solution, the solenoid valve can be closed by rotating the motor, and the airway in the valve body is opened. At the same time, the valve core is rotated to adjust the firepower, which provides a basis for electrically controlling the gas stove to start and stop and adjust the firepower. It also changes the traditional method of electronically controlling the gas stove to start and stop and adjust the firepower by controlling the proportional valve. At the same time, the use of the traditional valve core structure is safe and reliable, and is not prone to air leakage. The original vertical setting structure of the valve core is changed on the valve seat 1, and the valve core 2 is set horizontally or tilted, which changes the original vertical setting structure of the valve core, greatly reduces the height of the valve body to form an ultra-thin valve body.

[0026] Preferably, the valve seat 1 is also provided with a valve seat cover.

[0027] Furthermore, the drive motor 3 drives the valve core 2 to rotate via a gear 5, a pulley or a gear screw. The rotating shaft of the drive motor 3 and the valve core 2 move at a set rotation ratio to control the rotation of the valve core 2 through the drive motor 3. The transmission ratio is achieved through the gear size or the reduction gear set. The transmission ratio is set according to actual production needs. The user can start the stove with one click by controlling the speed of the drive motor 3 and the rotation angle of the motor shaft. The gear 5 is a straight tooth, a helical tooth or a conical tooth.

[0028] Furthermore, the valve core cavity 15 is formed into a cone to match the valve core 2 , and the large end of the valve core cavity 15 is provided with an air inlet end 151 , which is connected to the air passage 13 .

[0029] Furthermore, the valve core 2 forms a conical valve core 2 and cooperates with the valve core cavity 15. The valve core 2 is provided with an air inlet hole 21 that cooperates with the air inlet end 151. The conical surface of the valve core 2 is provided with an air hole 22 connected to the air outlet 12. The air channel 13 is connected to the large end of the valve core cavity 15 and enters from the air inlet hole 21 of the valve core 2. The valve core 2 is pressed toward the small end of the valve core 2 by the air pressure, so that the gap between the valve core 2 and the valve core cavity 15 becomes smaller, the sealing area is increased, the air tightness is improved, and the leakage caused by the center leakage of the gas valve core is avoided.

[0030] Furthermore, the valve core 2 is horizontally arranged in the valve seat 1 or tilted in the valve seat 1, and the valve core 2 is changed from the traditional vertical arrangement to the horizontal arrangement or tilted arrangement of the present technical solution, thereby reducing the height of the valve body 1 and changing the arrangement of the airway 13 to be diversified. Since the ejector pin of the traditional valve body is arranged in the middle of the valve core, the airway of the valve body can only be connected to the lower end of the valve body, which results in the valve body being pushed up by the gas when a fire breaks out, and the gas leaks from the gap between the ejector pin and the valve core, causing fire leakage. The ejector pin structure is cancelled in the present technical solution, and the gas will not leak from the center of the valve core. At the same time, by setting the air outlet position of the airway 13, the gas presses the valve core 2 toward the small end of the valve core 2, so that the valve core 2 is tightly attached to the valve core cavity 15, increasing the sealing area and thus improving the air tightness, avoiding air leakage, and eliminating the problem of air leakage from the center of the valve core, thus solving a major problem of air leakage and fire leakage of the valve body.

[0031] Furthermore, the driving motor 3 is installed in the valve seat 1 .

[0032] Furthermore, it is also provided with a push rod 8 and a shift rod 7, and a first shift block 71 and a second shift block 72 are provided at different angles of the shift rod 7. The second shift block 72 drives the push rod 8 to move toward the direction of the solenoid valve 4 so that the solenoid valve 4 is attracted. The driving motor 3 directly or indirectly drives the first shift block 71 to move around the axis of the shift rod 7 and then drives the second shift block 72 to move.

[0033] Further, when the drive motor 3 directly drives the first shift block 71 to move, at least one first drive block 31 is provided at the end of the motor shaft of the drive motor 3, and the first drive block 31 drives the first shift block 71 to move as the motor shaft of the drive motor 3 rotates. When the drive motor 3 indirectly drives the first shift block 71 to move, at least one second drive block is provided on the valve core 2, and the second drive block rotates as the valve core 2 rotates. The second drive block drives the first shift block 71 to move. The structure of the second drive block is consistent with that of the first drive block 31, and the second drive block is provided on the valve core 2.

[0034] Furthermore, a component 6 for converting angular displacement or linear displacement into an electrical signal is provided on the motor shaft of the driving motor 3 or the valve core 2 to record and send the angular displacement signal or linear displacement signal of the motor shaft or the valve core.

[0035] Preferably, the component 6 is a potentiometer, an adjustable resistor or an encoder.

[0036] A gas stove comprises the electric valve body mentioned above.

In the present technical solution, the solenoid valve can be closed by rotating the motor, and the airway in the valve body is opened. At the same time, the valve core is rotated to adjust the firepower, which provides a basis for electrically controlling the gas stove to start and stop and adjust the firepower. It also changes the traditional method of electronically controlling the gas stove to start and stop and adjust the firepower by controlling the proportional valve. At the same time, the use of the traditional valve core structure is safe and reliable, and is not prone to air leakage. The original vertical setting structure of the valve core is changed on the valve seat 1, and the valve core 2 is set horizontally or tilted, which changes the original vertical setting structure of the valve core, greatly reduces the height of the valve body to form an ultra-thin valve body.
