[0049] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0050] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or alternative features having similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features. Throughout the specification, the same reference numerals indicate the same elements.

[0051] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0052] At present, when the timed cooking of the integrated stove ends, the solenoid valve is usually used to automatically disconnect the gas pipe to turn off the fire, and then the knob is manually reset to close the mechanical valve; however, users often forget to reset the knob after timing. At this time, the mechanical valve is in an open state. If a child presses the knob down directly, the solenoid valve will connect the gas pipe while the knob is pressed, that is, there is no need to rotate the knob at the same time to start re-igniting. The function of the child lock cannot be guaranteed while achieving timed cooking, which is prone to safety problems and leads to low safety.

[0053] To this end, this embodiment proposes a valve body structure, a stove including the valve body structure, and an integrated stove including the stove; Figure 1 and Figure 2As shown, the integrated stove also includes a stove body 30, and the stove also includes a stove body 31; wherein a panel is installed on the stove body 30, the valve stem 21 in the valve body structure is inserted into the knob hole on the panel, and the knob 22 with interference fit on the end of the valve stem 21 can drive the valve stem 21 to rotate in the knob hole, so that the valve stem 21 controls the fire power of the stove body 31 by screwing the knob 22; the stove body 31 is installed on the panel, and an air pipe 32 is connected between the stove body 31 and the valve stem 21. wherein, multiple knob holes can be set on the panel to install multiple valve stems 21, and the number of knob holes and valve bodies is not limited here.

[0054] Furthermore, if Figure 1 and Figure 2 As shown, an air outlet is provided on the valve body structure, and the end of the air pipe 32 that is not connected to the stove main body 31 is connected to the air outlet. Turning the knob 22 can drive the valve stem 21 to rotate, so that the size of the air outlet can be adjusted by rotating the valve stem 21, thereby controlling the air flow in the air pipe 32 and realizing the control of the fire power of the stove main body 31; and a solenoid valve for opening and closing the air pipe 32 is provided on the air pipe 32.

[0055] It is worth noting that adjusting the fire power of the stove body 31 by turning the knob 22 is a common adjustment method in existing integrated stoves, and the solenoid valve and the gas pipe 32 are common structures in existing integrated stoves, which will not be described in detail here.

[0056] Specifically, Figure 2 and Figure 3 As shown, the valve body structure includes a drive assembly 10 and a valve body assembly 20 that are connected to each other. The drive assembly 10 is located below the panel, and the drive assembly 10 includes a first transmission member; the valve body assembly 20 includes a second transmission member, the above-mentioned valve stem 21 and the above-mentioned knob 22, the second transmission member is arranged on the valve stem 21, when the knob 22 is pressed downward and rotated, the second transmission member is meshed and connected with the first transmission member, so that the second transmission member can drive the first transmission member to rotate forward, so that the fire power of the stove main body 31 can be controlled by the rotation of the valve stem 21; at the end of timed cooking, the first transmission member can drive the second transmission member to rotate in the opposite direction until it is separated from the first transmission member, so that the valve stem 21 and the knob 22 are automatically reset.

[0057] Compared with the prior art, the valve body structure in this embodiment adds a drive assembly 10 used in conjunction with the valve body assembly 20; when manually turning the knob 22 to control the firepower, first press the knob 22 and rotate it. Since the second transmission member in the valve body assembly 20 is meshed and connected with the first transmission member in the drive assembly 10 at this time, the second transmission member can drive the first transmission member to rotate forward, and the drive assembly 10 will not interfere with the rotation of the knob 22 and the second transmission member, thereby ensuring normal firepower control of the knob 22; when the timed cooking is finished, the fire is automatically turned off by the solenoid valve in the valve body assembly 20, and the first transmission member starts to rotate in the opposite direction. Since the first transmission member and the second transmission member are still in meshing state at this time, , so the first transmission member can drive the second transmission member to rotate in the opposite direction until the second transmission member disengages from the first transmission member, that is, at this time the first transmission member and the second transmission member are disengaged, and the knob 22 is reset; the engagement or disengagement between the first transmission member and the second transmission member is used to realize the automatic resetting of the valve stem 21 and the knob 22, and there is no need to manually reset the knob 22 after the timing ends to close the valve body; because the solenoid valve and the valve stem 21 in the valve body structure are both in a closed state at this time, double-layer safety protection of the solenoid valve and the valve stem 21 is realized, so the child needs to press down the knob 22 and manually turn the knob 22 at the same time to start restarting, so that the entire valve body structure has the function of a child lock, is not prone to safety problems, and ensures high safety.

[0058] In this embodiment, Figure 2 and Figure 3 As shown, the first transmission member is the first gear 11, and the second transmission member is the second gear 23, so that the firepower adjustment and the automatic reset of the valve stem 21 can be achieved through the meshing connection or disengagement between the first gear 11 and the second gear 23. In other embodiments, one of the first transmission member and the second transmission member can be a rack, and the other can be a gear, so that the firepower adjustment and the automatic reset of the valve stem 21 can be achieved through the meshing connection or disengagement between the rack and the gear, which is not specifically limited here.

[0059] When the knob 22 is turned to adjust the fire power, the second gear 23 is required to drive the first gear 11 to rotate forward during the rotation process, that is, the first gear 11 will provide a resistance torque for the rotation of the second gear 23. Therefore, in this embodiment, the pitch circle diameter of the first gear 11 is larger than the pitch circle diameter of the second gear 23, so that the reduction ratio of the second gear 23 to the first gear 11 is smaller, thereby ensuring that the rotation resistance hindering the second gear 23 and the valve body during the forward rotation process is not too large, thereby ensuring a good user experience.

[0060] Furthermore, if Figures 2 to 4As shown, the driving assembly 10 further includes a mounting bracket 12 and a driving member 13; wherein the fixed end of the driving member 13 is mounted on the mounting bracket 12, the first gear 11 is sleeved on the output shaft 131 of the driving member 13, and the driving member 13 is used to drive the first gear 11 to rotate, so that the first gear 11 drives the second gear 23 to rotate in the opposite direction. Specifically, the driving member 13 can be a DC driving motor, a stepping driving motor or an AC driving motor.

[0061] Specifically, when the knob 22 is turned to adjust the fire power, the knob 22 drives the valve stem 21 to rotate, so that the valve stem 21 drives the second gear 23 to rotate, and at the same time the second gear 23 drives the first gear 11 to rotate. At this time, the driving member 13 is idling; when the timed cooking is finished, the driving member 13 is operated, and the output shaft 131 of the driving member 13 drives the first gear 11 to rotate in the opposite direction, so that the first gear 11 drives the second gear 23 to rotate, thereby driving the valve stem 21 and the knob 22 to rotate in the opposite direction until they are reset.

[0062] It is worth noting that the forward rotation and the reverse rotation in this embodiment are two opposite directions, and the forward rotation refers to the rotation direction of the first gear 11 and the rotation direction of the second gear 23 when the knob 22 is turned, and the reverse rotation refers to the rotation direction of the first gear 11 and the rotation direction of the second gear 23 after the timed cooking is completed and the driving member 13 is working. For example, when the forward rotation is counterclockwise, the reverse rotation is clockwise; when the forward rotation is clockwise, the reverse rotation is counterclockwise.

[0063] Specifically, if Figures 2 to 4 As shown, the part of the output shaft 131 passing through the mounting bracket 12 is respectively provided with a first limiting step 1311 and a clamping piece 14, and the first gear 11 is abutted and limited between the first limiting step 1311 and the clamping piece 14, so that the first gear 11 can be axially limited on the output shaft 131; at the same time, the center hole of the first gear 11 is a rectangular hole 111, and the output shaft 131 is a rectangular shaft. By inserting the rectangular shaft into the rectangular hole 111, the first gear 11 can be circumferentially limited on the output shaft 131, so as to ensure that the first gear 11 and the output shaft 131 rotate synchronously.

[0064] Specifically, Figures 2 to 4 As shown, a first mounting groove 1312 is further provided on the portion of the output shaft 131 passing through the mounting bracket 12, and the clamping member 14 is installed in the first mounting groove 1312; a first mounting hole 132 is provided on the driving member 13, and a second mounting hole 121 is provided on the mounting bracket 12, and a first fastener is connected to the first mounting hole 132 and the second mounting hole 121 to mount the driving member 13 on the mounting bracket 12. In this embodiment, the clamping member 14 is specifically a retaining spring, and the first fastener is a bolt.

[0065] Furthermore, if Figure 3 , Figures 5 to 9 As shown, the valve body assembly 20 further includes a limiting shaft 24 and an end cover 26; wherein the limiting shaft 24 is vertically arranged on the valve stem 21; the mounting bracket 12 in the drive assembly 10 is connected to the end cover 26, and a communicating limiting groove 262 and a second limiting step 263 are provided on the end cover 26, and one end of the valve stem 21 penetrates into the end cover 26; when the knob 22 is reset, the limiting shaft 24 is limited in the limiting groove 262, and the first gear 11 is disengaged from the second gear 23. At this time, the second gear 23 is higher than the first gear 11, as shown in FIG. Figure 6 and Figure 8 When the knob 22 is pressed and rotated, the second gear 23 moves downward to mesh with the first gear 11, and the limiting shaft 24 is driven by the valve stem 21 to disengage the limiting groove 262 and abut against the second limiting step 263, as shown Figure 7 and Fig. 9 As shown; due to the abutment of the second limiting step 263 on the limiting shaft 24, the limiting shaft 24 and the valve stem 21 can be prevented from moving upward, thereby ensuring that the first gear 11 and the second gear 23 are always in a meshing connection state.

[0066] Specifically, if Figures 2 to 5 As shown, the mounting bracket 12 is further provided with a third mounting hole 122 and an arcuate surface 123, and the end cover 26 is provided with a fourth mounting hole 265 and a circular boss 261. When the mounting bracket 12 is mounted on the end cover 26, the arcuate surface 123 is abutted against the circular boss 261, and the second fastener is connected to the third mounting hole 122 and the fourth mounting hole 265, so that the mounting bracket 12 can be mounted on the end cover 26. The valve stem 21 can pass through the circular boss 261, and the second fastener is a bolt.

[0067] Specifically, Figure 6 and Figure 7 As shown, a third limiting step 264 is also provided on the end cover 26, and the third limiting step 264 and the second limiting step 263 are arranged in a circle. The interval between the second limiting step 263 and the third limiting step 264 forms the above-mentioned limiting groove 262, and the bottom end surface of the third limiting step 264 is lower than the bottom end surface of the second limiting step 263; due to the resistance effect of the third limiting step 264 on the limiting shaft 24, it is ensured that the limiting shaft 24 can only rotate along the bottom end surface of the second limiting step 263.

[0068] Furthermore, if Figure 5As shown, a fourth limiting step 212 and a limiting member 25 are respectively provided on the portion of the valve stem 21 extending out of the end cover 26, and the second gear 23 is abutted and limited between the fourth limiting step 212 and the limiting member 25, so that the second gear 23 can be axially limited on the valve stem 21; at the same time, the center hole of the second gear 23 is a special-shaped hole 231, and the valve stem 21 is a special-shaped shaft. By inserting the special-shaped shaft into the special-shaped hole 231, the second gear 23 can be circumferentially limited on the valve stem 21, so as to ensure that the second gear 23 and the valve stem 21 rotate synchronously.

[0069] Specifically, if Figure 5 As shown, a second installation groove 211 is further provided on the portion of the valve stem 21 extending out of the end cover 26, and the limiting member 25 is installed in the second installation groove 211. In this embodiment, the limiting member 25 can be specifically a retaining spring.

[0070] Furthermore, if Figure 5 As shown, the valve body assembly 20 further includes a micro switch 29, which is disposed on the end cover 26 and located on one side of the circular boss 261. The micro switch 29 can provide a reset signal for the knob 22; when the first gear 11 drives the second gear 23 to rotate in the opposite direction to disengage from the first gear 11, the micro switch 29 can provide a reset signal to stop the driving member 13 from working. The micro switch 29 in this embodiment can adopt a common structure in the prior art.

[0071] Specifically, Figure 2 , Figure 6 and Figure 7 As shown, the valve body assembly 20 also includes a valve body 27 and an elastic member 28; wherein, the end cover 26 is provided on the open end of the valve body 27, the above-mentioned air outlet is provided on the valve body 27, and the above-mentioned solenoid valve is provided in the valve body 27; one end of the elastic member 28 is located in the valve body 27, and the other end of the elastic member 28 is connected to the valve stem 21, when the knob 22 is pressed downward, the valve stem 21 compresses the elastic member 28, so that the limiting shaft 24 can be elastically pressed to the bottom end surface of the second limiting step 263; when the first gear 11 drives the second gear 23 to rotate in the reverse direction, the limiting shaft 24 is moved to the position close to the limiting groove 262, and when the reverse rotation is continued, the limiting shaft 24 can automatically enter the limiting groove 262 under the elastic force of the elastic member 28, so that the limiting shaft 24 can be limited in the limiting groove 262. The elastic member 28 in this embodiment can be specifically a compression spring.

[0072] It is worth mentioning that the valve body structure can also include a sensor, and the sensor can be used to detect the temperature of the fire at the stove body 31 to control the rotation angle of the knob 22, thereby realizing intelligent functions such as reducing the fire when the pot is away, reducing the fire when the oil temperature is too high, or turning off the fire; this intelligent function can be realized by using the sensor and controller in the prior art, and the specific control process will not be described in detail here.

[0073] The specific working process of the valve body structure in this embodiment is as follows: Fig.10 As shown:

[0074] First, the initial position of the limiting shaft 24 is that the elastic member 28 is elastically abutted against the limiting groove 262. At this time, the valve stem 21 and the knob 22 are in a self-locking state. Figure 6 and Figure 8 As shown; when the valve stem 21 is pressed and rotated, the valve stem 21 and the limiting shaft 24 move downward, so that the limiting shaft 24 is disengaged from the limiting groove 262, and the valve stem 21 and the limiting shaft 24 continue to move downward for a certain distance until the limiting shaft 24 completely disengages from the limiting groove 262 and abuts against the bottom end surface of the second limiting step 263. At this time, the first gear 11 is meshed with the second gear 23, and the valve stem 21 does not move upward, as shown in FIG. Figure 7 and Fig. 9 As shown, during the rotation of the knob 22, the driving member 13 also rotates idly.

[0075] Then, when the timed cooking is finished, the solenoid valve in the valve body 27 first disconnects the air pipe 32 to extinguish the fire; then the driving member 13 is operated again. At this time, the first gear 11 and the second gear 23 are still in a meshing state, so that the driving member 13 drives the first gear 11, so that the first gear 11 drives the second gear 23 to rotate in the opposite direction. When the second gear 23 drives the limiting shaft 24 on the valve stem 21 to rotate to the limiting groove 262, it continues to rotate, so that the limiting shaft 24 can automatically abut against the limiting groove 262 under the elastic action of the elastic member 28. At this time, since the limiting shaft 24 moves upward from the second limiting step 263 to the limiting groove 262, the valve stem 21 and the knob 22 move upward to reset, and at this time the second gear 23 moves upward to disengage from the first gear 11, so that the first gear 11 and the second gear 23 are no longer meshed and connected. Figure 6 and Figure 8 As shown, the valve stem 21 and the knob 22 are automatically reset.

[0076] The valve body structure in this embodiment is provided with a first gear 11 and a second gear 23 which cooperate with each other, and the driving member 13 can drive the first gear 11 to rotate in the opposite direction. When the valve body structure is in a working state, the first gear 11 and the second gear 23 are in a meshing transmission state. When the valve stem 21 and the knob 22 in the valve body structure are reset, the first gear 11 and the second gear 23 are disengaged from the transmission, and the self-locking function of the valve body structure after automatic resetting is retained, so that the child lock function can be ensured while achieving timed cooking, so that the entire valve body structure and the integrated stove are safe to use, thereby improving user satisfaction and the quality, safety and reliability coefficient of the integrated stove.
