Description

Technical Field

[0001] The invention relates to a gas valve and a gas stove comprising the same. Background Art

[0002] The current gas stove controls the fire power of the stove by rotating the knob of the gas valve. Before ignition, the knob must be pressed down a certain distance, and the valve stem connected to the knob moves downward, driving the valve needle connected to the valve stem to move downward and push open the electromagnetic valve of the gas valve, so that the gas from the external gas source is connected to the gas valve.

[0003] When the user presses down and rotates the knob to ignite, the user needs to overcome the elastic force of multiple springs for the valve stem, valve needle and valve rebound of the solenoid valve when pressing the knob. This may cause the user to have difficulty pressing when igniting, causing the hand to slip and fall off the knob, resulting in poor ignition feel, ignition difficulty or ignition failure. This problem of hand loosening and flameout will make the gas stove using this gas valve inconvenient to use and poor user experience. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of poor ignition feel and difficulty in ignition of gas stoves in the prior art, and to provide a gas valve and a gas stove comprising the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A gas valve, comprising a valve body, a valve stem, a stopper and a solenoid valve, wherein the stopper has a first protrusion on a side away from the valve stem, the first protrusion is offset relative to a rotation axis of the stopper, and when the stopper rotates, the first protrusion can abut against or disengage from a valve surface of the solenoid valve;

[0007] When the first protrusion abuts against the valve, the valve is opened relative to the valve body;

[0008] When the first protrusion is separated from the valve, the valve is closed relative to the valve body.

[0009] In the present solution, the first protrusion is offset so that when the valve stem is rotated, the closing member is driven to rotate and the first protrusion can be rotated to the valve surface of the solenoid valve. The offset rotation can realize the smooth opening of the valve of the solenoid valve when igniting, and when the fire is turned off, the offset rotating first protrusion can give up the surface of the valve of the solenoid valve to realize the smooth closing of the solenoid valve, so as to avoid the occurrence of gas leakage caused by long-term pressing without rotating the valve stem when the user opens the valve of the battery valve by pressing the child lock, thereby improving the air tightness of the gas stove and preventing gas from leaking through the solenoid valve when the fire is turned off, thereby improving the safety of use, and reducing the setting of the spring by the first protrusion so that when the user uses it, only a small amount of elastic force needs to be overcome for ignition, without having to overcome multiple elastic forces, so as to improve the user's hand feel when using it, make ignition easier, and improve the success rate of ignition. In addition, the valve of the solenoid valve is opened by rotating the closing member, which is consistent with the way of opening the gas passage by rotating the closing member, so that the valve of the solenoid valve and the gas passage of the closing member are both opened by rotation, and the gas control synchronization is higher.

[0010] Preferably, a second protrusion is provided on a surface of the valve facing the first protrusion, and the first protrusion abuts against or separates from the second protrusion.

[0011] In this solution, the second protrusion is arranged along the axis of the solenoid valve, and the second protrusion corresponds to the first protrusion of the valve rotated to the solenoid valve. By arranging a relatively protruding second protrusion on the valve to contact the closer, the first protrusion of the closer is prevented from accidentally touching other positions of the valve during rotation, thereby causing the solenoid valve to fail to open.

[0012] Preferably, the second protrusion is located at the center of the valve.

[0013] In this solution, the second protrusion is located at the center of the valve, so that when the valve is opened by rotating the closer, the first protrusion and the second protrusion are balanced in force, and further, the first protrusion and the valve are balanced in force, thereby preventing the valve from being subjected to force on one side and concentrated on one side of the valve, causing the solenoid valve to get stuck along the opening direction of the valve.

[0014] Preferably, the peripheral edge of the second protrusion is an inclined surface or an arc-shaped surface.

[0015] In the present embodiment, the edge of the second protrusion is an inclined surface or an arc-shaped surface. The purpose is that when the first protrusion rotates to the second protrusion, the first protrusion first abuts against the edge of the second protrusion, and the passability of the first protrusion is improved by the inclined surface or the arc-shaped surface, that is, the guiding effect, so that the first protrusion can abut against the second protrusion smoothly, thereby improving the ignition success rate of the gas valve.

[0016] Preferably, the first protrusion is arranged on the surface of the closure, and relative to the body of the closure, the first protrusion can move along the direction of the rotation axis;

[0017] The closure further comprises an elastic member, and the elastic member is arranged between the body of the closure and the first protrusion.

[0018] In the present solution, an elastic member is provided so that the first protrusion can reciprocate vertically, so that when the first protrusion is rotated to the valve of the solenoid valve, the elastic member is compressed, and the first protrusion can smoothly push open the valve of the solenoid valve, thereby improving the service life of the solenoid valve and preventing the valve of the solenoid valve from being damaged when the gas valve is used multiple times due to the first protrusion being fixed. At the same time, the compressible first protrusion feels lighter in use than the fixed first protrusion, further improving the user experience.

[0019] Preferably, the elastic coefficient of the elastic member is greater than the elastic coefficient of the return spring of the solenoid valve.

[0020] In the present solution, on the basis of ensuring the user's hand feel, the elastic coefficient of the elastic part is greater than the elastic coefficient of the return spring of the solenoid valve, so as to ensure that the first protrusion can smoothly push open the valve of the solenoid valve, and avoid the situation where the first protrusion retracts relative to the closing part before pushing the valve open, thereby improving the ignition success rate of the gas valve.

[0021] Preferably, the gas valve further comprises a child lock mechanism, and the child lock mechanism is used to limit the rotation of the valve stem;

[0022] After the valve stem moves downward by a first preset distance relative to the child lock mechanism at the initial position, the valve stem can rotate relative to the child lock mechanism.

[0023] In this solution, the child lock mechanism can prevent the solenoid valve from opening due to accidental touching and pressing down on the valve stem. Compared with the structure of the valve that pushes down and opens the solenoid valve, this method retains the downward pressure for a certain distance and cooperates with the offset setting of the first protrusion. The solenoid valve can only be opened by rotating after being pressed down, which further improves the safety of the gas valve and prevents the solenoid valve from leaking gas due to downward pressure.

[0024] Preferably, the position of the first protrusion on the shutter is set such that when the shutter rotates from an initial position to a first preset angle, the first protrusion can abut against the valve;

[0025] The first preset angle has an angle range of 15° to 25°.

[0026] In the present solution, the rotation angle of the first protrusion is set, and its purpose is also to prevent the solenoid valve from leaking gas. When the user accidentally touches and presses down, the first protrusion will not push open the valve of the solenoid valve when the valve stem is slightly rotated. Only when the valve stem is rotated to a preset angle, the first protrusion will push open the valve of the solenoid valve, further improving the safety of the gas valve.

[0027] Preferably, the peripheral edge of the first protrusion is an inclined surface or an arc-shaped surface.

[0028] In this embodiment, the edge of the first protrusion is also set as an inclined surface or an arc surface, so that when the first protrusion is rotated to the valve of the solenoid valve, it can more smoothly abut against the surface of the valve. Its purpose is also to provide guidance and enhance the user's feel.

[0029] Preferably, the opening direction of the valve is the same as the direction of the rotation axis of the closer.

[0030] In this solution, the valve opening direction is made the same as the rotation axis of the closer, which is beneficial for the first protrusion to push the valve open along the valve opening direction through the rotation of the closer, thereby avoiding the valve from getting stuck during the opening process. This is a preferred structural setting of the present application.

[0031] A gas stove adopts any one of the gas valves described above.

[0032] The positive progressive effect of the present invention is that the present invention opens the valve of the solenoid valve through the first protrusion offset on the closure, and the valve stem is rotatably connected to the closure and drives the first protrusion to rotate to the surface of the valve, which not only avoids the occurrence of gas leakage caused by long-term pressing without rotating the valve stem when the user opens the valve by pressing the child lock, but also eliminates the valve needle and the return spring of the valve needle to reduce the user's downward force during ignition, improves the user's feel, and ensures the safety of gas use. The structure is simple and the gas valve has higher air tightness. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0055] The specific structure of the gas valve is as follows Figure 3 As shown, the gas valve includes a valve body 1, a valve stem 2, a closure 3 and a solenoid valve 4. The valve stem 2 is located above the closure 3 and the valve stem 2 is rotatably connected to the closure 3. The closure 3 fits against the inner wall of the valve body 1 to ensure the air tightness of the valve body 1. A gas through hole 301 is provided in the closure 3. When the valve stem 2 drives the closure 3 to rotate and the gas through hole 301 is connected to the gas passage 101 in the valve body 1, the gas can flow from the solenoid valve 4 to the gas passage 101 and be ignited by the burner.

[0056] This embodiment provides a gas valve, such as Figure 1 , Figure 2 and Figure 3As shown, the closure 3 and the electromagnetic valve 4 are arranged vertically, the closure 3 is located above the electromagnetic valve 4, and the side of the closure 3 away from the valve stem 2 has a first protrusion 31, the first protrusion 31 is arranged vertically and is higher than the end surface of the side of the closure 3 away from the valve stem 2, and the first protrusion 31 is offset relative to the rotation axis of the closure 3, that is, the axis of the first protrusion 31 does not coincide with the axis of the closure 3, and the first protrusion 31 is arranged offset from the axis of the closure 3. This design ensures that when the closure 3 rotates with the valve stem 2, the first protrusion 31 will not always be located at the center of the end surface of the closure 3, but when the first protrusion 3 rotates at a certain angle, 1 will rotate to a designated position, which is the upper surface of the valve 41 of the solenoid valve 4. Since the height of the first protrusion 31 is higher than the end surface of the closure 3, when the closure 3 rotates, the first protrusion 31 can rotate and abut against the upper surface of the valve 41, and the valve 41 is pushed open by the first protrusion 31 so that the gas in the solenoid valve 4 can flow into the gas valve through the valve 41 and be used normally by the gas valve. The state in which the first protrusion 31 pushes the solenoid valve 4 open is the ignition state of the gas valve, and the closed state of the solenoid valve 4 is the rotation angle of the closure 3 when the first protrusion 31 is away from the valve 41. When the valve 41 is opened, the first protrusion 31 rotated in an offset manner makes way for the upper surface of the valve 41 of the solenoid valve 4, so that the solenoid valve 4 is smoothly closed. At this time, the gas through hole 301 of the closer 3 has not yet been connected to the gas passage 101 of the valve body 1, that is, the plug seal of the closer 3 relative to the valve body 1 has not yet been opened, so as to avoid the gas leakage caused by long-term pressing and ignition failure when the user opens the valve 41 by pressing the child lock, thereby improving the air tightness and safety of the gas stove. In addition, compared with the gas valve in which the valve stem 2 presses down the valve needle and the valve needle pushes up the solenoid valve 4, the first protrusion 31 has a 31 is directly arranged on the closure 3, and the arrangement of the valve needle and the spring for resetting the valve needle is reduced, so that when the user uses it, it is only necessary to overcome a small amount of elastic force for ignition, without having to overcome multiple elastic forces, thereby reducing the downward force required for the user to ignite and improving the user's hand feel when using it, making ignition easier and improving the ignition success rate. In addition, the valve 41 of the solenoid valve 4 is opened by the rotation of the closure 3, so that the first protrusion 31 opens the solenoid valve 4 in the same way as the closure 3 rotates to open the gas passage 101, so that the valve 41 of the solenoid valve 4 and the gas passage 101 of the closure 3 are both opened by rotation, and the gas control synchronization is higher.

[0057] At the same time, if Figure 3 , Figure 4As shown, the valve 41 is a circular plate, and a second protrusion 42 is provided on the upper surface of the valve 41 vertically upward. The second protrusion 42 is arranged toward the first protrusion 31 on the shutter 3, and the axis of the second protrusion 42 coincides with the axis of the solenoid valve 4. Since the height of the second protrusion 42 is higher than the height of the valve 41, when the first protrusion 31 rotates to the valve 41, the first protrusion 31 abuts against the second protrusion 42 and pushes the valve 41 open along the opening direction of the solenoid valve 4. In the height direction, the upper surface height of the second protrusion 42 is higher than the lower surface height of the first protrusion 31, so as to ensure that the valve 41 is opened. To ensure that the first protrusion 31 and the second protrusion 42 can contact smoothly, similarly, in order to ensure that the first protrusion 31 and the second protrusion 42 can contact smoothly, the lower surface height of the first protrusion 31 is higher than the end surface of the closer 3 close to the solenoid valve 4, that is, the first protrusion 31 is protruded from the closer 3, and a relatively protruding second protrusion 42 is provided on the valve 41 to contact the first protrusion 31, so as to avoid the first protrusion 31 of the closer 3 accidentally touching other positions of the valve 41 during the rotation process, thereby causing the valve 41 of the solenoid valve 4 to fail to open, thereby further improving the ignition success rate of the gas valve.

[0058] It can be understood that the second protrusion 42 in this embodiment is located at the center of the valve 41 .

[0059] Specifically, the second protrusion 42 is a cylindrical part, and the axis of the cylindrical part coincides with the axis of the valve 41. When the valve 41 is opened by the rotation of the closer 3, the first protrusion 31 contacts the second protrusion 42, and the second protrusion 42 is the force center of gravity of the valve 41. The downward pressure applied by the first protrusion 31 is evenly transmitted to the valve 41 through the second protrusion 42, that is, the second protrusion 42 and the valve 41 are balanced in force, thereby avoiding the situation that when the second protrusion 42 is offset on the valve 41, the force applied by the first protrusion 31 is concentrated on one side of the valve 41, while the other side of the valve 41 is inclined and abuts against the inner wall of the solenoid valve 4, making it impossible for the valve 41 to open along the opening direction of the solenoid valve 4, that is, it can avoid the situation that when the force is unbalanced, one side of the valve 41 is subjected to force and concentrated on one side of the valve 41, and the valve 41 is stuck in the opening direction of the solenoid valve 4.

[0060] Furthermore, if Figure 4 , Figure 6 As shown, the peripheral edge of the second protrusion 42 is an inclined surface or an arc surface, such as Figure 5 , Figure 7As shown, the edge of the cylindrical part is chamfered. On the one hand, it will not scratch the operator when installing the second protrusion 42. On the other hand, when the first protrusion 31 rotates to the second protrusion 42, the first protrusion 31 first abuts against the edge of the second protrusion 42, and the passability of the first protrusion 31 is improved by the inclined surface or the arc surface, that is, the guiding effect, which makes it easier for the first protrusion 31 to abut against the upper surface of the second protrusion 42. This not only improves the user's operating feel during use, but also ensures that the second protrusion 42 can still smoothly contact the first protrusion 31 after multiple uses, thereby improving the reuse rate of the gas valve.

[0061] Correspondingly, the peripheral edge of the first protrusion 31 is an inclined surface or an arc surface. The first protrusion 31 is a cylindrical part and the edge of the first protrusion 31 is also set as an inclined surface or an arc surface. Similar to the chamfered edge of the second protrusion 42, the edge of the first protrusion 31 can also improve the user's operating feel during use, and can ensure that the first protrusion 31 can still smoothly contact the second protrusion 42 after multiple uses, thereby improving the service life of the gas valve.

[0062] In this embodiment, if Figure 3 , Figure 7 As shown, the closure 3 further includes an elastic member 32, which is disposed between the body of the closure 3 and the first protrusion 31. A mounting groove is provided on the closure 3 corresponding to the first protrusion 31, and the elastic member 32 is disposed in the mounting groove and one end of the elastic member 32 is connected to the first protrusion 31. The elastic member 32 is a spring. Of course, the elastic member 32 can also use other resilient structures. This is a prior art and will not be described in detail here. By providing the elastic member 32, the first protrusion 31 can reciprocate vertically. When the first protrusion 31 rotates to the valve 41 of the solenoid valve 4, one end of the first protrusion 31 contacts the edge of the second protrusion 42. At this time, the elastic member 32 is compressed, and the other end of the first protrusion 31 extends into the mounting groove, so that the first protrusion 31 can be smoothly rotated to the upper surface of the second protrusion 42. Compared with the fixed first protrusion 31, the first protrusion 31 that can perform reciprocating motion is improved in terms of both the feel of use and the multiple service life of the first protrusion 31.

[0063] Furthermore, a reset spring is provided in the solenoid valve 4 , and the reset spring is used to reset the valve 41 and reseal the solenoid valve 4 when the first protrusion 31 of the valve 41 is away from the second protrusion 42 .

[0064] It is understandable that the elastic coefficient of the elastic member 32 is greater than the elastic coefficient of the return spring of the solenoid valve 4. On the basis of improving the user's hand feeling, the elastic coefficient of the elastic member 32 is greater than the elastic coefficient of the return spring of the solenoid valve 4 to ensure that the first protrusion 31 can smoothly and completely push open the valve 41 of the solenoid valve 4, and avoid the situation where the first protrusion 31 does not push open the valve 41 and retracts along the installation groove. By setting the elastic coefficient and stroke of the elastic member 32, it is ensured that each time the first protrusion 31 rotates past the second protrusion 42, the solenoid valve 4 can be fully opened to prevent the hand from loosening and stalling.

[0065] Preferably, Figure 8 As shown, the lower surface of the first protrusion 31 is higher than the mounting surface 11 in the valve body 1 for mounting the shutter 3, that is, the lower surface of the first protrusion 31 will not contact the mounting surface 11 when the first protrusion 31 rotates, so as to ensure a good hand feel during rotation without excess friction.

[0066] In addition, in the present embodiment, the gas valve further includes a child lock mechanism 5, one end of the child lock mechanism 5 is clamped on the valve stem 2 along the horizontal direction of the valve stem 2, and when the valve stem 2 is pressed down, the child lock mechanism 5 and the valve stem 2 are unlocked, and the child lock mechanism 5 is used to limit the rotation of the valve stem 2. The child lock mechanism 5 can avoid the opening of the solenoid valve 4 caused by accidentally touching and rotating the valve stem 2. After the valve stem 2 moves downward by a first preset distance relative to the child lock mechanism 5 in the initial position, the valve stem 2 can rotate relative to the child lock mechanism 5. This method retains the downward pressure for a certain distance and cooperates with the offset setting of the first protrusion 31. The solenoid valve 4 can be opened only after rotation after being pressed down, which further improves the safety of the gas valve. This is a prior art and will not be elaborated on here.

[0067] In this embodiment, a downward pressure groove is provided on the closure 3, and the downward pressure groove is located at the end portion where the closure 3 is connected to the valve stem 2. The downward pressure groove is used to accommodate the distance that the valve stem 2 moves downward when ignited, that is, when ignited, the valve stem 2 is pressed down to the bottom of the downward pressure groove, and the downward pressure groove is not connected to the solenoid valve 4, that is, the gas through hole 301 of the closure 3 is not connected to the downward pressure groove, and when the closure 3 rotates, the first protrusion 31 rotates to the second protrusion 42 on the valve 41 and opens the solenoid valve 4 to flow out, and the gas flows into the gas of the closure 3. The through hole 301 is connected with the gas passage 101 when the closer 3 rotates, and the gas flows to the gas passage 101 and is used for normal ignition of the gas stove. The valve needle originally inserted in the closer 3 is replaced by the first protrusion 31, so that the structure of the closer 3 itself is closed. The gas flows into the gas through hole 301 and accumulates in the gas through hole 301 without leaking from the valve stem 2, thereby improving the air tightness of the gas valve, and cooperating with the valve 41 of the solenoid valve 4 to seal the solenoid valve 4, thereby realizing double sealing of the gas valve.

[0068] In addition, a notch is provided on the inner wall of one side of the downward pressure groove, and a cross bar is provided in the horizontal direction corresponding to the notch on the valve stem 2, and the cross bar cooperates with the notch in the vertical direction, that is, when the valve stem 2 is pressed down, the cross bar moves downward vertically and slides into the notch, and the valve stem 2 can drive the closing member 3 to rotate accordingly through the cooperation between the cross bar and the notch.

[0069] In this embodiment, the outer peripheral side of the closer 3 is fitted with the inner wall of the valve body 1, the closer 3 rotates in the valve body 1, the axis of the closer 3 does not coincide with the axis of the solenoid valve 4, and the position of the first protrusion 31 on the closer 3 is set to: when the closer 3 rotates from the initial position by a first preset angle, the first protrusion 31 can abut against the valve 41, that is, the first protrusion 31 will not abut against the valve 41 when the closer 3 is slightly rotated, and only when the closer 3 is rotated by 15° to 25°, the first protrusion 31 will abut against the upper surface of the valve 41, and its purpose is also to prevent the solenoid valve 4 from leaking. When the user touches and presses the valve stem 2 by mistake, the slightly rotated valve stem 2 drives the closure 3 to rotate, so as to prevent the first protrusion 31 from pushing open the valve 41 of the solenoid valve 4. Only when the valve stem 2 rotates to a preset angle, the first protrusion 31 will push open the valve 41 of the solenoid valve 4, further improving the safety of the use of the gas valve. Preferably, the first preset angle is 20°. In addition, since the gas through hole 301 and the gas passage 101 in this embodiment are connected by rotation and are closed by the closure 3 cock before connection, in order to improve the safety of the use of the gas valve, a second preset angle is also provided. When the closure 3 rotates to the second preset angle, the closure 3 is opened by rotating the cock seal relative to the valve body 1. Preferably, the second preset angle should be achieved by increasing 25° to 35° on the basis of the first preset angle, that is, only after the closure 3 is rotated to the first preset angle and continues to rotate, the gas through hole 301 can be connected to the gas passage 101 (that is, the stopcock seal of the closure 3 relative to the valve body 1 is opened) by rotating to the second preset angle of 25° to 35°. For example, in this embodiment, when the first preset angle is preferably 20°, when it is rotated to 20°, the closure 3 opens the valve 41 of the solenoid valve 4, and the second preset angle is preferably 50°, after it is rotated to 50°, the gas through hole 301 is connected to the gas passage 101, so as to avoid gas leakage due to the opening of the solenoid valve 4 and the connection of the gas through hole 301 to the gas passage 101 when the valve body 1 is kept at the first preset angle after an accidental flameout.

[0070] The present embodiment also provides a gas stove, which adopts the gas valve as mentioned above, adopts an offset first protrusion 31, and ignites by rotating the first protrusion 31 and pushing open the valve 41 of the solenoid valve 4 to improve the user's feeling of use and ensure the smooth ignition of the gas stove, which not only improves the airtightness of the gas stove, but also makes the gas flow into the gas passage 101 and the opening of the solenoid valve 4 synchronous, thereby improving the synchronization of gas control.
