[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] In the description of the present application, it should be understood that the terms "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] like Figure 1-Figure 4 As shown, this embodiment provides a stove valve, including a valve body 1, a valve cover 2, a valve core 3 and a valve stem 4. The valve core 3 is installed in the valve body 1, and the valve stem 4 is connected to the valve core 3 to drive the valve core 3 to rotate, thereby adjusting the opening of the valve core 3 to achieve the adjustment of the firepower.

[0048] Specifically, a positioning plate 11 is provided between the upper end of the valve body 1 and the valve cover 2, and the fastening screws are sequentially passed through the connection holes on the valve cover 2 and the positioning plate 11 to be screwed and fixed to the valve body 1, and the inner cavity of the valve cover 2 is formed between the positioning plate 11 and the inner wall of the valve cover 2, and a micro switch 25 is also installed on the valve cover 2, and a conical head 251 is installed on the contact of the micro switch 25, and a groove 44 is provided on the outer peripheral wall of the valve stem 4. In the initial state, the contact of the micro switch 25 naturally extends, and the conical head 251 is stuck in the groove 44 of the valve stem 4. When the user presses down the valve stem 4, the position of the groove 44 moves down, and the conical head 251 leaves the groove 44 and presses on the outer peripheral wall of the valve stem 4, squeezing the contact, so that the micro switch 25 is actuated, and then the circuit is connected to start ignition. A valve core needle 31 is provided in the valve core 3, and a lifting spring 32 and a lifting plate 33 are sleeved on the valve core needle 31. One end of the valve core needle 31 is pushed into the positioning groove 45 at the bottom of the valve stem 4. After the user releases the valve stem 4, the valve stem 4 is lifted up by the lifting spring 32 and resets to the initial state. The lower end of the valve body 1 is connected to the bottom cover 14 by a fastening screw, and a sealing ring 13 is also provided between the valve body 1 and the bottom cover 14 to ensure sealing.

[0049] The stove valve also includes components such as an air regulating plate 8, a nozzle 9, a solenoid valve 10 and a lever 12. The air regulating plate 8, the nozzle 9 and the solenoid valve 10 are arranged on one side of the valve body 1. The lever 12 is arranged in the valve body 1 and connected to the valve core 3. The valve core 3 rotates to adjust the air outlet area of ​​the air regulating plate 8 through the lever 12, thereby adjusting the firepower. The specific structure of the connection between the valve body 1 and the valve core 3, and the specific structure of the connection between the valve core 3 and the air regulating plate 8, the nozzle 9, the solenoid valve 10 and the lever 12 are not the improvement points of the utility model, and will not be repeated here.

[0050] In order to achieve precise adjustment of the gear position of the stove valve, the stove valve provided in this embodiment also includes a gear plate 5 and a gear adjustment member 7. The gear plate 5 is rotatably arranged in the inner cavity of the valve cover 2. A through hole 55 is arranged on the gear plate 5. A limiting groove 54 is arranged on the inner wall of the through hole 55. A limiting pin 6 is arranged on the outer side of the valve stem 4. The valve stem 4 extends out of the valve cover 2 after passing through the through hole 55. The limiting pin 6 is plugged into the limiting groove 54, so that when the valve stem 4 is rotated, the gear plate 5 can be driven to rotate through the limiting pin 6. A plurality of gear grooves 511 are arranged on the top of the gear plate 5 along the circumferential direction. The opening sizes of the valve core 3 corresponding to different gear grooves 511 are different, thereby corresponding to multiple gears, which is convenient for adjusting different gears and meets the precise adjustment of different flame sizes.

[0051] The top of the valve cover 2 is provided with a mounting hole 24, and the gear adjustment member 7 is telescopically arranged in the mounting hole 24, and is used to be engaged with the gear slot 511, and when the gear plate 5 rotates with the valve stem 4, the gear adjustment member 7 can switch between different gear slots 511. The gear adjustment member 7 is telescopically arranged in the mounting hole 24 at the top of the valve cover 2, and when the gear plate 5 rotates with the valve stem 4, the gear adjustment member 7 can cooperate with different gear slots 511 around the gear plate 5, and when the valve stem 4 rotates to a suitable angle and stops rotating, the gear adjustment member 7 slides into the gear slot 511 aligned with it and engages with the gear slot 511, so as to adjust the appropriate gear. The stove valve has multiple gears, and the user can adjust different gears by rotating the valve stem 4, which meets the demand for precise fire control.

[0052] In addition, a plurality of gear slots 511 are arranged in the circumferential direction of the top of the gear plate 5 , so that a greater number of gear slots 511 can be arranged without increasing the volume of the valve cover 2 , thereby making the gear adjustment more precise.

[0053] Specifically, Figure 5 As shown, the plurality of gear slots 511 are evenly distributed or partially evenly distributed along the circumference of the gear plate 5 , and the positions of the corresponding gear slots 511 can be precisely set according to the actual firepower required.

[0054] In this embodiment, there are eleven gear slots 511, the first two gear slots 511 are high fire gear and low fire gear respectively, and the firepower corresponding to the other nine gear slots 511 behind the low fire gear decreases in sequence. The spacing between the first two gear slots 511 is greater than the spacing between the other nine gear slots 511 behind, and the spacing between the gear slot 511 corresponding to the low fire gear and the other nine gear slots 511 is greater than the spacing between the first two gear slots 511. With this arrangement, the user can make more precise firepower adjustments for the low fire when using it, meeting the user's usage needs.

[0055] The gear adjustment member 7 is arranged in the mounting hole 24 at the top of the valve cover 2. When the gear plate 5 rotates with the valve stem 4, the gear adjustment member 7 reciprocates up and down in the mounting hole 24. During the rotation of the gear plate 5, the gear adjustment member 7 gradually moves upward in the gear slot 511, slides to the plane between adjacent gear slots 511, and then slides from the plane between adjacent gear slots 511 to the next gear slot 511. The gear adjustment member 7 is also affected by its own gravity. The gear adjustment member 7 enters the gear slot 511 under the action of its own gravity. When the user operates, on the one hand, a good gear shifting feel is formed, and on the other hand, the smoothness of the rotation of the valve stem 4 is increased.

[0056] Furthermore, the shift groove 511 is configured as an arc-shaped groove. The groove surface of the arc-shaped groove is an arc surface, which makes it easier for the shift adjusting member 7 to slide in and out during the rotation of the shift plate 5, further improving the smoothness of the rotation of the valve stem 4.

[0057] Furthermore, one end of the arc groove passes through the outer peripheral surface of the shift plate 5. Such a configuration makes it easier to process the arc groove, reduces the processing difficulty, and improves production efficiency.

[0058] Specifically, Figure 5 and Figure 6 As shown, the shift plate 5 includes a plate body 51 and a first sleeve 52, a shift groove 511 is provided at the top of the plate body 51, the first sleeve 52 is provided protruding from the top of the plate body 51, and the inner hole of the first sleeve 52 forms a through hole 55. By providing the first sleeve 52, the matching area between the shift plate 5 and the valve stem 4 is increased, when the valve stem 4 rotates, the swing of the valve stem 4 relative to the shift plate 5 is small, and the shift adjusting member 7 is not easy to slide out due to the swing of the valve stem 4 after entering the shift groove 511, thereby preventing the valve stem 4 from being disengaged due to accidental rotation, thereby ensuring the reliability of the shift adjustment of the stove valve.

[0059] Furthermore, the shift plate 5 further comprises a first protrusion 53, which is arranged outside the first sleeve 52 and extends toward the edge of the plate body 51, and the limiting groove 54 extends from the bottom of the plate body 51 toward the inside of the first protrusion 53. Such a configuration increases the depth of the limiting groove 54, ensures the stability of the matching between the limiting groove 54 and the limiting pin 6, and further ensures that the shift plate 5 always rotates with the rotation of the valve stem 4, avoiding the problem that the shift plate 5 cannot rotate with the valve stem 4 due to the mismatch between the limiting pin 6 and the limiting groove 54, resulting in the inability to adjust the gear position; and without increasing the thickness of the plate body 51, the first protrusion 53 can also separate the maximum gear and the minimum gear of the gear groove 511 on the plate body 51, avoiding the gear adjustment member 7 from sliding directly from the gear groove 511 of the maximum firepower to the gear groove 511 of the minimum firepower during rotation.

[0060] Specifically, Figure 4 , Figure 7-Figure 9 As shown, the valve cover 2 includes a cover body 21, a second sleeve 22 and a second protrusion 23. The second sleeve 22 and the second protrusion 23 are both arranged at the top of the cover body 21. The valve stem 4 extends out of the valve cover 2 through the inner hole of the second sleeve 22. The second protrusion 23 is arranged on the outside of the second sleeve 22 and extends to the edge of the cover body 21. The mounting hole 24 extends from the bottom of the cover body 21 to the inside of the second protrusion 23. The arrangement of the second sleeve 22 increases the matching area of ​​the valve stem 4 and the valve cover 2, further reduces the swing amplitude of the valve stem 4 when rotating, and avoids the gear adjustment member 7 from being disengaged due to the valve stem 4 rotating due to accidental contact. The arrangement of the second protrusion 23 increases the design depth of the mounting hole 24, so that the gear adjustment member 7 can be aligned with the gear groove 511 of the gear plate 5 in the circumferential direction.

[0061] The structure of the gear adjustment member 7 can be set in various forms, such as Figure 4 and Figure 7As shown, in one embodiment, the gear adjustment member 7 includes an elastic member 71 and a bead 72. The mounting hole 24 is communicated with the inner cavity of the valve cover 2. The elastic member 71 and the bead 72 are both arranged in the mounting hole 24. The bead 72 is used to be engaged with the gear slot 511. The elastic member 71 is connected to the bead 72 to provide the bead 72 with an elastic force in the direction of the gear plate 5. Under the elastic force of the elastic member 71, the bead 72 is extended and retracted in the mounting hole 24, so that the bead 72 slides into or out of the gear slot 511 when the gear plate 5 rotates.

[0062] The mounting hole 24 can be configured to only penetrate the inner cavity of the valve cover 2 . When the mounting hole 24 only penetrates the inner cavity of the valve cover 2 , the bottom of the mounting hole 24 is closed, and the end of the elastic member 71 away from the bead 72 can directly abut against the bottom of the mounting hole 24 .

[0063] In one embodiment, the mounting hole 24 can also be set to be connected not only to the inner cavity of the valve cover 2, but also to the end of the second protrusion 23 away from the cover body 21. The gear adjustment member 7 also includes a stop screw 73. The mounting hole 24 is set to pass through the top of the valve cover 2. The stop screw 73 extends from the outer side of the top of the valve cover 2 into the mounting hole 24 and is screwed to the mounting hole 24. The elastic member 71 is arranged between the stop screw 73 and the bead 72. The matching depth of the elastic member 71 and the bead 72 with the mounting hole 24 is adjusted by the stop screw 73, so that the bead 72 and the gear groove 511 cannot be effectively matched due to the depth error of the mounting hole 24, thereby reducing the processing difficulty of the mounting hole 24.

[0064] The elastic member 71 is a spring, and the bead 72 can be a steel ball or a bead made of other materials.

[0065] In one embodiment, if Figure 8 and Fig. 9 As shown, the gear adjustment member 7 is a positioning bead, the mounting hole 24 is connected to the inner cavity of the valve cover 2, the positioning bead is arranged in the mounting hole 24, and the movable end of the positioning bead is arranged toward the inner cavity of the valve cover 2. The positioning bead is also called a ball plunger or a spring plunger, which is an integrated structure composed of a shell, a spring, a ball or a column. The movable end of the positioning bead is the plunger end. The positioning bead is a finished product that can be purchased from outside, and the positioning bead can be directly installed in the mounting hole 24 that only penetrates the inner cavity of the valve cover 2.

[0066] In order to ensure the safety of the stove valve, the stove valve is generally required to have a self-locking structure, that is, when the user does not press the valve stem 4 to ignite, the valve stem 4 cannot drive the gear plate 5 and the valve core 3 to rotate.

[0067] like Figure 10-Figure 14As shown, a limit rod is provided on the outer peripheral wall of one end of the valve stem 4 connected to the valve core 3, and a self-locking boss 111 is provided on the lower surface of the positioning plate 11, and the self-locking boss 111 extends along the circumferential direction of the positioning plate 11. When the valve stem 4 is not pressed down, the limit rod abuts against one end of the self-locking boss 111, so that the valve stem 4 cannot rotate, forming a self-locking protection. When the user uses it, the valve stem 4 can be rotated to adjust the gear position only after the valve stem 4 is pressed down to ignite.

[0068] The limiting rod can be provided as an integral structure with the valve stem 4, or can be provided as a separate structure with the valve stem 4. The provision of an integral structure can reduce the assembly steps, and the provision of a separate structure facilitates the installation of the valve stem 4.

[0069] In one embodiment, if Fig.10 and Fig.11 As shown, the limit rod is configured as a square lever 41 which is an integral structure with the valve stem 4. During assembly, the upper end of the valve stem 4 passes through the positioning pressure plate 11, the shift plate 5 and the valve cover 2 in sequence. The square lever 41 remains below the positioning pressure plate 11 and can directly cooperate with the self-locking boss 111 on the positioning pressure plate 11 to achieve self-locking protection.

[0070] In one embodiment, if Figure 12-14 As shown, a latch hole 42 is provided on the outer peripheral wall of one end of the valve stem 4 connected to the valve core 3, and the limiting rod is a latch 43. After the valve stem 4, the positioning pressure plate 11, the shift plate 5 and the valve cover 2 are installed, the latch 43 is inserted into the latch hole 42, so that the latch 43 can cooperate with the self-locking boss 111 to realize self-locking protection.

[0071] This embodiment also provides a stove, including a panel, a fire adjustment knob and a stove valve as described above, wherein the fire adjustment knob is arranged at the end of the valve stem 4 away from the valve core 3, and a gear mark is arranged on the fire adjustment knob corresponding to the gear slot 511. The stove valve is installed below the panel, and the fire adjustment knob is arranged above the panel. The end of the valve stem 4 away from the valve core 3 extends out of the panel and is connected to the fire adjustment knob. There are multiple gear marks corresponding to the multiple gear slots 511, each representing a different firepower. When the user uses it, the valve stem 4 is rotated according to the gear mark on the fire adjustment knob. When the valve stem 4 is rotated to the corresponding gear mark, the firepower is adjusted to the corresponding size. The user can adjust the firepower size intuitively and accurately according to the multiple gear marks, thereby improving the user experience.

[0072] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
