Description

Technical Field

[0001] The utility model relates to the field of stoves, in particular to a stove cock valve and a stove. Background Art

[0002] Most of the existing stove cock valves are operated by pressing down to unlock the child lock and then rotating to adjust the firepower. The solenoid valve and the cock seal are opened through the valve stem. If the downward stroke is not enough, the solenoid valve is not pressed and attracted, which will cause the solenoid valve to close after the user releases his hand, resulting in flameout. However, the entire movement stroke of "pressing down the valve stem-driving the valve needle-driving the fork-pushing the solenoid valve" is very long, with a large tolerance size and several springs. In order to save effort, it is usually achieved by setting the lever arm of the fork. After saving effort, the downward stroke is longer, and if the stroke is too long, it is easier to loosen the hand and flame out. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects in the prior art that the structure movement of the stove cock valve is too long and the flame is easily extinguished by hand, and to provide a stove cock valve and a stove.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A gas cock valve, comprising:

[0006] The valve body comprises a first valve cavity, a second valve cavity and a gas passage, wherein the first valve cavity and the second valve cavity are arranged at intervals in the horizontal direction; the upper end port of the first valve cavity is the air outlet of the first valve cavity, the lower end port of the second valve cavity is the air inlet of the second valve cavity, the air outlet of the first valve cavity is connected with the air inlet of the second valve cavity through the gas passage, the air inlet of the first valve cavity is connected with the gas pipeline, and the air outlet of the second valve cavity is connected with the fire cover of the stove;

[0007] A solenoid valve assembly, comprising a first valve stem and a first valve core, wherein the first valve core is disposed in the first valve cavity, the first valve stem extends in a vertical direction, the lower end of the first valve stem is connected to the first valve core, the upper end of the first valve stem passes through the valve body and can extend above the cooker panel, the first valve stem can drive the first valve core to move between a first position and a second position relative to the valve body in a vertical direction; when the first valve core is located in the first position, an air outlet of the first valve cavity is closed; when the first valve core is located in the second position, an air outlet of the first valve cavity is opened;

[0008] The plug valve assembly includes a second valve stem and a second valve core, wherein the second valve core is arranged in the second valve cavity, the lower end of the second valve stem is connected to the second valve core, the upper end of the first valve stem passes through the valve body and can extend above the stove panel, and the second valve stem can drive the second valve core to rotate around its own axis to adjust the opening of the air outlet of the second valve cavity.

[0009] In this solution, the first valve cavity is connected to the gas pipeline, and the solenoid valve assembly is used to control whether the gas in the gas pipeline can enter the gas cock. The second valve cavity is connected to the fire cover, and the cock valve assembly is used to control the gas flux from the second valve cavity to the fire cover to adjust the size of the flame. In this solution, the solenoid valve assembly and the cock valve assembly are independently arranged, and no transmission member is arranged between the solenoid valve assembly and the cock valve assembly. The user can directly control the first valve stem and the second valve stem independently to control the opening of the first valve cavity and adjust the opening of the air outlet of the second valve cavity respectively. The first valve core directly bears the force applied by the user on the first valve stem, and the stroke of force transmission is shortened. The user can also press the first valve stem to the bottom by applying a smaller force to ensure that the air outlet of the first valve cavity remains in a normally open state, which is convenient for the circulation of gas and prevents the flame from being extinguished by loose hands. In addition, the actions of pressing down and rotating are respectively realized by different valve stems, which makes the operation easier, and the first valve stem is easier to press to the bottom to prevent the flame from being extinguished by loose hands.

[0010] Preferably, the solenoid valve assembly also includes a retaining member, which is disposed below the first valve core and fixed to the valve body, wherein the retaining member is at least partially located in the first valve cavity, and the retaining member can be attracted to the first valve core to keep the first valve core in the second position.

[0011] In this solution, the retainer is used to ensure that the gas outlet of the first valve cavity remains in a normally open state, which facilitates the flow of gas and prevents the flame from being extinguished by loose hands. The suction method is simple to operate, has low difficulty in alignment, and is easy to operate.

[0012] Preferably, the solenoid valve assembly further comprises a thermocouple, the thermocouple comprising a fixed portion, a movable portion and a reset portion, the movable portion being movably connected to an upper end of the fixed portion through the reset portion, the lower end of the fixed portion being fixedly connected to the valve body, and the first valve stem being connected to an end of the movable portion away from the fixed portion in a vertical direction;

[0013] The fixed part forms the retaining member, and the movable part forms the first valve core; when the sensing temperature of the thermocouple is greater than or equal to a preset temperature, the fixed part and the movable part are attracted; when the sensing temperature of the thermocouple is lower than the preset temperature, the fixed part and the movable part are not attracted.

[0014] In this solution, when the stove is working, the temperature rises. According to the characteristics of the thermocouple, after the user presses the first valve stem, the first valve core can be adsorbed on the retaining member to maintain the air outlet of the first valve cavity normally open. After the stove finishes working, the temperature drops, the retaining member no longer adsorbs the first valve core, and the first valve core is reset to the first position under the action of the reset part to close the air outlet of the first valve cavity. The thermocouple structure can adapt to a high temperature environment and is suitable for stoves.

[0015] Preferably, the thermocouple is arranged at the lower end of the first valve cavity and is partially located outside the first valve cavity, the thermocouple is closed and connected to the lower end port of the first valve cavity, and the air inlet of the first valve cavity is arranged on the peripheral side wall of the first valve cavity.

[0016] Preferably, the retaining member is a magnet, and the first valve core is made of metal.

[0017] In this solution, the first valve core is attracted to the retaining member by magnetic attraction, which has a simple structure and is easy to operate. The user can pull the first valve stem upward to reset the first valve core, which has higher reliability.

[0018] Preferably, the solenoid valve assembly further comprises a sealing member, the sealing member is arranged in the first valve cavity and located above the first valve core, the sealing member is sleeved on the first valve stem, and the sealing member can move along the vertical direction following the first valve stem;

[0019] When the first valve core is located at the first position, the sealing member blocks the air outlet of the first valve cavity.

[0020] In this solution, the seal is used to prevent gas leakage and improve safety.

[0021] Preferably, the solenoid valve assembly further comprises a stopper, the stopper being fixed to the upper end surface of the retaining member; the stopper has a concave cavity with an opening facing downward, the upper end surface of the stopper has a through hole penetrating in a vertical direction, the first valve stem passes through the through hole and extends into the concave cavity, and the first valve core is arranged in the concave cavity;

[0022] When the first valve core is in the first position, the upper end surface of the first valve core abuts against the upper wall surface of the concave cavity.

[0023] In this solution, the limiter can limit the excessive upward movement of the first valve core when the user pulls up the first valve stem, so as to prevent the sealing member, the first valve core and other structures from being pulled out of the first valve cavity, thereby ensuring reliability of use.

[0024] Preferably, the solenoid valve assembly also includes a first reset member, which is sleeved on the first valve stem, and the two ends of the first reset member in the vertical direction are respectively abutted against the sealing member and the limit member, and the first reset member is used to apply a force to the sealing member in a direction away from the limit member.

[0025] In this solution, the first resetting member indirectly achieves the resetting of the first valve core by applying a force to the sealing member, thereby preventing the user from failing to pull up the first valve core and causing the air outlet of the first valve cavity to not be completely closed.

[0026] Preferably, the solenoid valve assembly further comprises a pressing portion, wherein the pressing portion is fixed to an upper end surface of the first valve stem, and a diameter of the pressing portion is greater than a diameter of the first valve stem.

[0029] In this solution, the user can directly manipulate the first valve stem and the second valve stem independently to control the opening of the first valve cavity and adjust the opening of the air outlet of the second valve cavity respectively. The first valve core directly bears the force applied by the user to the first valve stem, and the force transmission stroke is shortened. The user can press the first valve stem to the bottom with a smaller force to ensure that the air outlet of the first valve cavity remains in a normally open state, which facilitates the circulation of gas and prevents the flame from being extinguished by loose hands. In addition, the actions of pressing down and rotating are respectively realized by different valve stems, which makes the operation easier and the first valve stem is easier to press to the bottom to prevent the flame from being extinguished by loose hands.

The user can directly operate the first valve stem and the second valve stem independently to control the opening of the first valve cavity and adjust the opening of the air outlet of the second valve cavity respectively. The first valve core directly bears the force applied by the user on the first valve stem, and the stroke of force transmission is shortened. The user can press the first valve stem to the bottom with a smaller force to ensure that the air outlet of the first valve cavity remains in a normally open state, which is convenient for the circulation of gas and prevents the flame from being extinguished by loose hands.

[0071] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0072] Example 1

[0073] like Figure 1 As shown, this embodiment discloses a stove, including a stove panel 11, a fire cover (not shown in the figure) and a gas cock 12, the fire cover is connected to the gas outlet of the gas cock 12, and the gas cock 12 is used to provide gas to the fire cover. The fire cover is installed above the stove panel 11 and is used to generate flames. The gas cock 12 is used to control the gas entering the stove, and can adjust the gas flux according to the needs of the user to adjust the size of the flame at the fire cover. Among them, the method of connecting the gas cock 12 and the fire cover belongs to the prior art and is not described here.

[0074] like Figure 2-Figure 5 As shown, the gas cock valve 12 includes a valve body 2 , a solenoid valve assembly 3 and a cock valve assembly 4 .

[0075] like Figure 3 , Figure 5 and Figure 6 As shown, the valve body 2 has a first valve cavity 21, a second valve cavity 22 and a gas passage 23. The first valve cavity 21 and the second valve cavity 22 are arranged horizontally at intervals. Specifically, the first valve cavity 21 and the second valve cavity 22 in this embodiment are substantially at the same height position of the valve body 2.

[0076] like Figure 5 and Figure 6 As shown, the first valve cavity 21 extends in the vertical direction, the upper end port of the first valve cavity 21 is the air outlet 211 of the first valve cavity, and the air inlet 212 of the first valve cavity is arranged on the peripheral side wall of the first valve cavity 21. The second valve cavity 22 extends in the vertical direction, the lower end port of the second valve cavity 22 is the air inlet 221 of the second valve cavity, and the air outlet 222 of the second valve cavity is arranged on the peripheral side wall of the second valve cavity 22. The air inlet 212 of the first valve cavity is connected to the gas pipeline (not shown in the figure), the air outlet 211 of the first valve cavity is connected to the air inlet 221 of the second valve cavity through the gas channel 23, and the air outlet 222 of the second valve cavity is connected to the fire cover of the stove.

[0077] like Figure 4 As shown by the arrows in the figure, the gas in the gas pipeline enters the interior of the first valve cavity 21 through the air inlet 212 of the first valve cavity, flows into the gas channel 23 through the air outlet 211 of the first valve cavity, and then flows into the interior of the second valve cavity 22 from the air inlet 221 of the second valve cavity through the gas channel 23, and finally flows to the fire cover from the air outlet 222 of the second valve cavity.

[0078] Among them, Figure 4 As shown, the gas channel 23 includes a first air inlet section 231 and a second air inlet section 232. The first air inlet section 231 extends in a horizontal direction, and the second air inlet section 232 extends in a vertical direction. One end of the first air inlet section 231 is connected to the air outlet 211 of the first valve cavity, and the other end of the first air inlet section 231 is connected to the upper end of the second air inlet section 232. The lower end of the second air inlet section 232 is connected to the air inlet 221 of the second valve cavity.

[0079] like Figure 3 and Figure 7 As shown, the solenoid valve assembly 3 includes a first valve stem 31 , a first valve core 32 , a retaining member 33 and a first restoring member 34 .

[0080] like Figure 3As shown, the first valve core 32 is disposed in the first valve cavity 21, the first valve stem 31 extends in the vertical direction, the lower end of the first valve stem 31 is connected to the first valve core 32, and the upper end of the first valve stem 31 passes through the valve body 2 and extends above the cooker panel 11. The first valve stem 31 can move in the vertical direction relative to the valve body 2, and because the first valve stem 31 is fixedly connected to the first valve core 32, the first valve stem 31 can drive the first valve core 32 to move between the first position and the second position in the vertical direction relative to the valve body 2.

[0081] When the first valve core 32 is located at the first position, the gas outlet 211 of the first valve cavity is closed, and the gas in the first valve cavity 21 cannot flow to the second valve cavity 22. When the first valve core 32 is located at the second position, the gas outlet 211 of the first valve cavity is opened, and the gas in the first valve cavity 21 can flow to the second valve cavity 22.

[0082] like Figure 3 As shown, the retainer 33 is disposed below the first valve core 32 and fixed on the valve body 2, and the retainer 33 is at least partially located in the first valve cavity 21. When the first valve core 32 moves to the second position, the retainer 33 can be attracted to the first valve core 32 to keep the first valve core 32 in the second position, so that the gas outlet 211 of the first valve cavity is maintained in a normally open state, which facilitates the flow of gas and prevents the flame from being extinguished by loose hands. The attraction method is simple to operate, has low difficulty in alignment, and is easy to operate.

[0083] like Figure 3 and Figure 7 As shown, the first reset member 34 is disposed between the first valve core 32 and the retaining member 33, and the two ends of the first reset member 34 in the vertical direction are respectively in contact with the lower end surface of the first valve core 32 and the upper end surface of the retaining member 33. The first reset member 34 is used to apply a force to the first valve core 32 in the vertical direction toward the air outlet 211 of the first valve cavity, so as to help the first valve core 32 to reset from the second position to the first position, and can keep the first valve core 32 in the first position, so as to keep the air outlet 211 of the first valve cavity normally closed, thereby improving the safety of the cooker.

[0084] The first restoring member 34 in this embodiment is a coil spring. In other alternative implementations, the first restoring member 34 may also be other restoring structures that can achieve the above functions.

[0085] like Figure 3 As shown, the plug valve assembly 4 includes a second valve stem 41, a second valve core 42 and a second reset member 43. The second valve core 42 is disposed in the second valve cavity 22, and the lower end of the second valve stem 41 is connected to the second valve core 42. The second valve stem 41 can drive the second valve core 42 to rotate around its own axis to adjust the opening of the gas outlet 222 of the second valve cavity, control the gas flux from the second valve cavity 22 to the fire cover, and adjust the size of the flame.

[0086] Specifically, the second valve core 42 is provided with a plurality of flow holes 421 of different sizes, and the plurality of flow holes 421 of different sizes are arranged at intervals along the circumference of the second valve core 42. The user can rotate the second valve stem 41 to drive the second valve core 42 to rotate, so as to adjust the flow holes 421 aligned with the gas outlet 222 of the second valve cavity, thereby adjusting the gas flux. The second reset member 43 is connected to the second valve cavity 22, and is used to control the second valve cavity 22 to rotate along its own axis to reset.

[0087] Among them, the specific structure of the plug valve assembly 4 belongs to the existing technology and will not be described here.

[0088] In this embodiment, the solenoid valve assembly 3 and the plug valve assembly 4 are independently arranged, and no transmission member is arranged between the solenoid valve assembly 3 and the plug valve assembly 4. Since the first valve stem 31 and the second valve stem 41 both extend to the top of the stove panel 11, the user can directly operate the first valve stem 31 and the second valve stem 41 independently to control the opening of the first valve cavity 21 and adjust the opening of the gas outlet 222 of the second valve cavity. The first valve core 32 directly bears the force applied by the user on the first valve stem 31, and the stroke of force transmission is shortened. The user can also press the first valve stem 31 to the bottom by applying a smaller force to ensure that the gas outlet 211 of the first valve cavity maintains a normally open state, facilitate the circulation of gas, and prevent the hand from loosening and extinguishing the flame. In addition, the actions of pressing down and rotating are respectively realized by different valve stems, which makes the operation easier, and the first valve stem 31 is easier to press to the bottom to prevent the hand from loosening and extinguishing the flame.

[0089] Specifically, Figure 3 and Figure 7 As shown, the solenoid valve assembly 3 also includes a thermocouple, which has a fixed portion 51, a movable portion 52 and a reset portion 53. The fixed portion 51 forms a retaining member 33, the movable portion 52 forms a first valve core 32, and the reset portion 53 forms a first reset member 34. Specifically, the lower end of the first valve cavity 21 is open, the fixed portion 51 is arranged at the lower end of the first valve cavity 21 and is partially located outside the first valve cavity 21, the lower end of the fixed portion 51 is fixedly connected to the valve body 2 and the connection with the lower end port of the first valve cavity 21 is closed to prevent gas leakage. The lower end of the reset portion 53 is connected to the upper end of the fixed portion 51, the movable portion 52 is connected to the upper end of the reset portion 53 and is movably connected to the upper end of the fixed portion 51 through the reset portion 53, and the first valve stem 31 is connected to one end of the movable portion 52 away from the fixed portion 51 in the vertical direction.

[0090] When the sensed temperature of the thermocouple is greater than or equal to the preset temperature, the fixed portion 51 and the movable portion 52 are attracted, the first valve core 32 moves from the first position to the second position, and the air outlet 211 of the first valve cavity is opened. When the sensed temperature of the thermocouple is less than the preset temperature, the fixed portion 51 is not attracted to the movable portion 52, the first valve core 32 remains in the first position, and the air outlet 211 of the first valve cavity is closed.

[0091] When the stove is working, the temperature rises. According to the characteristics of the thermocouple, after the user presses the first valve stem 31, the first valve core 32 can be adsorbed on the retaining member 33 to keep the air outlet 211 of the first valve cavity normally open. After the stove finishes working, the temperature drops, the retaining member 33 no longer adsorbs the first valve core 32, and the first valve core 32 is reset to the first position under the action of the reset part 53 to close the air outlet 211 of the first valve cavity. The thermocouple structure can adapt to the environment with higher temperature and is suitable for stoves.

[0092] The working principle of thermocouple belongs to the prior art and will not be described in detail here.

[0093] Furthermore, if Figure 3 As shown, the solenoid valve assembly 3 further includes a pressing portion 6, which is fixed to the upper end of the first valve stem 31, and the diameter of the pressing portion 6 is greater than the diameter of the first valve stem 31. The pressing portion 6 increases the user's operating area and improves the user's operating experience.

[0094] The pressing portion 6 and the first valve stem 31 in this embodiment are separately processed and then assembled. In other alternative implementations, the pressing portion 6 and the first valve stem 31 may also be integrally formed.

[0095] Example 2

[0096] The structures of the stove and the gas cock 12 in this embodiment are basically the same as those in Embodiment 1, except that:

[0097] like Figure 8 and Fig. 9 As shown, the solenoid valve assembly 3 includes a first valve stem 31 , a first valve core 32 , a retaining member 33 , a sealing member 35 , a limiting member 36 and a first restoring member 34 .

[0098] like Figure 8 As shown, the retaining member 33 in this embodiment is a magnet, and the material of the first valve core 32 is a metal material. The first valve core 32 is attracted to the retaining member 33 by magnetic attraction, which has a simple structure and is easy to operate. The user can pull the first valve stem 31 upward to reset the first valve core 32, which has higher reliability.

[0099] like Figure 8 As shown, the seal 35 is disposed in the first valve cavity 21 and above the first valve core 32. The seal 35 is sleeved on the first valve stem 31, and the seal 35 can move along the vertical direction with the first valve stem 31. When the first valve core 32 is located at the first position, the seal 35 blocks the gas outlet 211 of the first valve cavity to close the gas outlet 211 of the first valve cavity. The seal 35 is used to prevent gas leakage and improve safety.

[0100] like Figure 8As shown, the stopper 36 is fixed on the upper end surface of the retaining member 33, and the stopper 36 has a concave cavity 362 with an opening facing downward, and the upper end surface of the stopper 36 has a through hole 361 penetrating in the vertical direction, and the first valve stem 31 extends into the concave cavity 362 through the through hole 361, and the first valve core 32 is arranged in the concave cavity 362. When the first valve core 32 is in the first position, the upper end surface of the first valve core 32 abuts against the upper wall surface of the concave cavity 362. The stopper 36 can limit the excessive upward movement of the first valve core 32 when the user pulls up the first valve stem 31, so as to prevent the sealing member 35, the first valve core 32 and other structures from being pulled out of the first valve cavity 21, thereby ensuring the reliability of use.

[0101] like Figure 8 As shown, the first reset member 34 is sleeved on the first valve stem 31, and the two ends of the first reset member 34 in the vertical direction are respectively in contact with the sealing member 35 and the limiting member 36, and the first reset member 34 is used to apply a force to the sealing member 35 in a direction away from the limiting member 36. The first reset member 34 indirectly achieves the reset of the first valve core 32 by applying a force to the sealing member 35, preventing the user from pulling up the valve incompletely, causing the air outlet 211 of the first valve cavity to be not completely closed.

[0102] The first restoring member 34 in this embodiment is a coil spring. In other alternative implementations, the first restoring member 34 may also be other restoring structures that can achieve the above functions.

[0103] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the normal use of the device or component, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0104] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
