Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of cookers, in particular to a gas stove. BACKGROUND

[0002] A gas stove is a device used for cooking, which produces a flame by burning a combustible gas (such as natural gas, liquefied petroleum gas or artificial gas) to heat a pot and food. Among them, the gas stove with the function of explosive frying is more and more popular with users. By starting the explosive frying function, the heat load is instantaneously increased, and the firepower is immediately increased to meet the user's firepower cooking needs.

[0003] In related technologies, the gas stove includes a gas stove body and a plug valve arranged on the gas stove body. The plug valve includes a valve body, a valve rod, a first limiting structure, a second limiting structure, a first switch, a second switch, etc. Among them, the valve rod cooperates with the first switch to control ignition or start explosive frying, and the valve rod cooperates with the second switch to identify whether the fire is on.

[0004] However, when the valve rod is rotated from the first limiting structure to the second limiting structure, the valve rod is limited by the second limiting structure, and the valve rod cannot be pressed down, resulting in that the explosive frying function cannot be realized, which affects the user's explosive frying experience. Utility model content

[0005] Embodiments of the present application provide a plug valve, which has a larger range of opening explosive frying function and better user experience.

[0006] In a first aspect, embodiments of the present application provide a gas stove, comprising:

[0007] a gas stove body;

[0008] a plug valve connected with the gas stove body, the plug valve comprising:

[0009] a valve rod structure;

[0010] a resilient member connected with the valve rod structure;

[0011] a first switch configured to start the explosive frying mode of the gas stove when the valve rod structure moves downward to trigger the first switch while the gas stove is in the ignition state;

[0012] a valve body provided with a first accommodating cavity, the valve rod structure being inserted in the first accommodating cavity, and the valve rod structure being movably connected with the valve body;

[0013] a first limiting structure located in the first accommodating cavity;

[0014] a second limiting structure located in the first accommodating cavity, the second limiting structure and the first limiting structure being arranged at intervals along the circumference of the first accommodating cavity, and the top of the second limiting structure being provided with a relief portion for avoiding the valve rod structure;

[0015] When the gas stove is in an unignited state, the valve rod structure is close to the first limiting structure; under the action of the first external force, the valve rod structure moves downward to compress the elastic member and rotates toward the second limiting structure, so that the gas stove is in an ignited state; after the first external force is cancelled, the valve rod structure moves upward under the action of the elastic member; when the valve rod structure is located between the end of the first limiting structure facing the avoiding portion and the end of the avoiding portion away from the first limiting structure, under the action of the second external force, the valve rod structure moves downward to trigger the first switch.

[0016] The gas stove provided by the application comprises a gas stove body and a plug valve, wherein the plug valve comprises a valve rod structure, an elastic member, a first switch, a valve body, a first limiting structure and a second limiting structure. The valve body is provided with a first accommodating cavity, the valve rod structure is inserted in the first accommodating cavity, and the valve rod structure is movably connected with the valve body. The second limiting structure and the first limiting structure are arranged at intervals along the circumference of the first accommodating cavity, and the top of the second limiting structure is provided with an avoiding portion for avoiding the valve rod structure. The first switch is configured such that when the gas stove is in an ignited state and the valve rod structure moves downward to trigger the first switch, the gas stove starts the explosive frying mode. When the gas stove is in an unignited state, the valve rod structure is close to the first limiting structure. Under the action of the first external force, the valve rod structure moves downward to compress the elastic member and rotates toward the second limiting structure, so that the gas stove is in an ignited state; after the first external force is cancelled, the valve rod structure moves upward under the action of the elastic member. When the valve rod structure is located between the end of the first limiting structure facing the avoiding portion and the end of the avoiding portion away from the first limiting structure, under the action of the second external force, the valve rod structure moves downward to trigger the first switch, thereby starting the explosive frying mode. In this way, the valve rod structure moves downward through the avoiding portion to trigger the first switch, which increases the opening angle range of the explosive frying mode and improves the user experience.

[0017] In some embodiments, the end of the avoiding portion facing the first limiting structure is flush with the end of the second limiting structure facing the first limiting structure.

[0018] In this way, the opening angle of the explosive frying mode is continuous, and the valve rod structure can start the explosive frying mode when it is located between the end of the first limiting structure facing the avoiding portion and the end of the avoiding portion away from the first limiting structure, which is beneficial to improve the user experience.

[0019] In some embodiments, the central angle corresponding to the region between the end of the second limiting structure facing the first limiting structure and the end of the first limiting structure facing the avoiding portion is 90°.

[0020] In this way, the plug valve corresponds to the ignition operation of the conventional gas stove, which is convenient for user operation.

[0021] In some embodiments, the central angle corresponding to the avoiding portion is greater than 20° and less than 40°.

[0022] When the central angle corresponding to the avoiding part is less than 20°, it is not easy to meet the needs of users, and the user experience is poor. When the central angle corresponding to the avoiding part is greater than 40°, the valve rod structure is rotated to a small fire state, and the valve rod structure is pressed to start the stir-frying mode. At this time, the burner needs a large heat load, and the stir-frying effect is poor.

[0023] In some embodiments, the plug valve further comprises a third limiting structure, the third limiting structure is connected to the side of the second limiting structure away from the avoiding part;

[0024] In the height direction, the height of the top of the third limiting structure is higher than the height of the top of the second limiting structure, and the height of the top of the first limiting structure is higher than the height of the top of the second limiting structure.

[0025] In this way, after the valve rod structure is reset under the elastic force of the elastic member, the third limiting structure and the second limiting structure can still effectively limit the valve rod structure.

[0026] In some embodiments, the valve rod structure comprises:

[0027] The valve rod, the lower part of the valve rod is provided with a contact part, and when the gas stove is in an unignited state, the contact part abuts against the first limiting structure;

[0028] The pressing piece is located above the first switch, and the pressing piece is rotationally connected with the valve rod. The valve rod drives the pressing piece to move in the height direction, so that the pressing piece triggers or does not trigger the first switch.

[0029] In this way, the angle of the pressing piece relative to the first switch remains unchanged. By pressing, the valve rod drives the pressing piece to move downward to trigger the stir-frying mode. The movement of the pressing piece is single, which is conducive to improving the reliability of the pressing piece triggering the first switch.

[0030] In some embodiments, the valve rod structure further comprises a push piece, the push piece is connected with the valve rod, the valve rod drives the push piece to rotate, and the valve rod drives the push piece to move;

[0031] The plug valve further comprises a second switch, and when the gas stove is in an unignited state, the push piece triggers the second switch.

[0032] In this way, through the cooperation of the push piece and the second switch, the ignition condition can be fed back in time.

[0033] In some embodiments, the valve rod structure further comprises a limiting piece, the limiting piece is connected with the valve rod, the valve rod drives the limiting piece to rotate, and the valve rod drives the limiting piece to move, and the limiting piece is provided with a first limiting part;

[0034] The plug valve further comprises a valve cover arranged above the valve body, the valve cover is provided with a second accommodating cavity in communication with the first accommodating cavity, the valve rod structure is inserted into the second accommodating cavity, and an inner wall of the second accommodating cavity is provided with a second limiting portion matched with the first limiting portion, and the first limiting portion is connected with the second limiting portion to limit rotation of the valve rod.

[0035] In this way, the valve rod structure can rotate only in the depressed state through cooperation of the first limiting portion and the second limiting portion.

[0036] In some embodiments, the first distance is between the pressing piece and the first switch when the gas stove is in an unignited state.

[0037] The size of the avoiding portion in the height direction is greater than the first distance.

[0038] In this way, it is beneficial to ensure that the valve rod structure can trigger the first switch.

[0039] In a second aspect, the embodiments of the present application provide a gas stove, comprising:

[0040] A gas stove body;

[0041] A plug valve connected with the gas stove body, the plug valve comprising:

[0042] A valve rod structure;

[0043] An elastic member connected with the valve rod structure;

[0044] A first switch configured to open a blow-frying mode of the gas stove when the gas stove is in an ignited state and the valve rod structure moves downward to trigger the first switch;

[0045] A valve body provided with a first accommodating cavity, the valve rod structure being inserted into the first accommodating cavity, and the valve rod structure being movably connected with the valve body;

[0046] A first limiting structure located in the first accommodating cavity;

[0048] In this way, the valve rod structure moves downward through the avoiding portion to trigger the first switch, increases an opening angle range of the blow-frying mode, and improves user experience. BRIEF DESCRIPTION OF DRAWINGS

[0075] As described in the background, when the plug valve is rotated from 0 degree to 90 degrees, the valve rod cannot continue to rotate due to the second limiting structure, so that the plug valve is in the maximum firepower position. However, because the pressable range required by the stir-frying function is 60-120 degrees, the second limiting structure causes the valve rod to be unable to be pressed in the range of 90-120 degrees, which leads to the failure of the stir-frying function and affects the user's stir-frying experience.

[0076] In order to solve the above technical problems, the gas stove provided by the present application comprises a gas stove body and a plug valve, wherein the plug valve comprises a valve rod structure, an elastic member, a first switch, a valve body, a first limiting structure and a second limiting structure. The valve body is provided with a first accommodating cavity, the valve rod structure is inserted in the first accommodating cavity, and the valve rod structure is movably connected with the valve body. The second limiting structure and the first limiting structure are arranged in a circumferential direction of the first accommodating cavity, and the top of the second limiting structure is provided with a avoiding portion for avoiding the valve rod structure. When the gas stove is in an ignition state, the valve rod structure is moved downward to trigger the first switch, and the gas stove is opened in a flash frying mode. When the gas stove is in an unignition state, the valve rod structure is close to the first limiting structure. Under the action of a first external force, the valve rod structure is moved downward to compress the elastic member and is rotated towards the second limiting structure, so that the gas stove is in the ignition state. After the first external force is cancelled, the valve rod structure is moved upward under the action of the elastic member. When the valve rod structure is located between one end of the first limiting structure facing the avoiding portion and one end of the avoiding portion away from the first limiting structure, under the action of a second external force, the valve rod structure is moved downward to trigger the first switch, thereby opening the flash frying mode. In this way, the valve rod structure is moved downward through the avoiding portion to trigger the first switch, the opening angle range of the flash frying mode is increased, and the user experience is improved.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0084] The embodiments of the present application provide a gas stove, wherein the gas stove comprises a gas stove body.

[0085] In some embodiments, the gas stove body comprises a shell, which can play a role in containing and protecting other devices.

[0086] In some embodiments, the shell comprises a bottom shell. The bottom shell encloses an installation cavity with an opening. The installation cavity can be used to contain components such as burners.

[0087] Specifically, in some embodiments, the bottom shell can include a side plate and a bottom plate. The side plate is located on one side of the bottom plate and is arranged around the periphery of the bottom plate. The bottom plate and the side plate enclose the installation cavity.

[0088] For example, the bottom plate and the side plate can enclose a cuboid-shaped installation cavity. It can be understood that the shape of the installation cavity can be designed according to actual conditions, which is not limited further here.

[0089] In some embodiments, the shell comprises a panel. The panel can be used to carry and support objects.

[0090] The panel is arranged on the top of the bottom shell, and the panel is used to cover part of the opening of the installation cavity.

[0091] In some embodiments, the gas stove body includes a burner. The burner can be used to generate flame and heat to heat cookware.

[0092] It should be noted that the number of burners is at least one. The burner provided in this embodiment can be a flat-plate burner or a dry-burning-proof burner; therefore, there is no specific limitation on the type of burner.

[0093] In some embodiments, the number of burners is at least two, and the at least two burners are spaced apart.

[0094] For example, the number of burners can be one, two, three, or four, etc.

[0095] The burner is embedded in the top of the housing. Specifically, the panel has a clearance opening to allow space for the burner. This clearance opening allows the burner to be placed so that it can heat the cookware.

[0096] In some embodiments, the panel has a touch area. The touch area can be used to control the gas stove body, adjust the flame, and select functions. The touch area of ​​the panel enables users to conveniently operate the gas stove body, realizing intelligent operation of the gas stove.

[0097] In some embodiments, the gas stove body includes a pot-and-cook support. The pot-and-cook support serves to concentrate energy and support the cookware.

[0098] The energy-concentrating pan support is fitted around the outside of the burner and is located on top of the casing. The bottom of the energy-concentrating pan support abuts against the top of the casing.

[0099] In some embodiments, the gas stove includes a stopcock valve. The stopcock valve is operated by the user to turn the gas stove on and off and to control the flame intensity, etc.

[0100] The stopcock valve is connected to the gas stove body. Specifically, the stopcock valve is embedded in the top of the housing, with part of the stopcock valve located on the outside of the housing and part of the stopcock valve located inside the housing.

[0101] Figure 1 This is a schematic diagram of the structure of the plug valve provided in an embodiment of this application. Figure 2 for Figure 1 A structural diagram from another angle. Figure 3 for Figure 1 Exploded view.

[0102] See Figures 1 to 3 As shown, the plug valve includes a valve stem structure 100. A user can press the valve stem structure 100, thereby allowing the valve stem structure 100 to move downwards and to rotate.

[0103] In some embodiments, the plug valve comprises an elastic member (not shown in the figure). The elastic member is used to provide elastic restoring force, so as to move the valve rod structure 100 upward along the height direction to reset.

[0104] The elastic member is connected with the valve rod structure 100.

[0105] In some embodiments, the plug valve comprises a first switch 200. The first switch 200 is configured to be triggered when the valve rod structure 100 moves downward to the first switch 200 when the gas stove is in the ignition state, and the gas stove is turned on to the stir-frying mode.

[0106] Figure 4 A structure diagram of the valve body and the valve rod in the plug valve provided by the embodiments of the present application, Figure 5 A structure diagram of the valve body in the plug valve provided by the embodiments of the present application, Figure 4 A partial enlarged view of position A in FIG. 4, Figure 6 A structure diagram of the valve body in the plug valve provided by the embodiments of the present application, Figure 7 A structure diagram of the valve body in the plug valve provided by the embodiments of the present application, Figure 6 A partial enlarged view of position B in FIG. 5.

[0107] Referring to FIG. 6, Figures 4 to 7 In some embodiments, the plug valve comprises a valve body 300.

[0108] The valve body 300 is provided with a first accommodating cavity 310, the valve rod structure 100 is inserted into the first accommodating cavity 310, and the valve rod structure 100 is movably connected with the valve body 300.

[0109] In some embodiments, the plug valve comprises a first limiting structure 400. The first limiting structure 400 is used to limit the rotation direction of the valve rod structure 100, so that when the user ignites, the valve rod structure 100 rotates towards the direction of the second limiting structure 500.

[0110] The first limiting structure 400 is located in the first accommodating cavity 310. The first limiting structure 400 can be located at the 0° position of the valve rod structure 100.

[0111] In some embodiments, the first limiting structure 400 is integrally arranged with the valve body 300.

[0112] In some embodiments, the plug valve comprises a second limiting structure 500. The second limiting structure 500 is used to limit the position of the maximum fire, so that when the user ignites, the valve rod structure 100 can be rotated to the position of the maximum fire. It should be noted that when igniting, the user presses the valve rod structure 100 and rotates the valve rod structure 100 until the valve rod structure 100 abuts against the second limiting structure 500, at which time the position of the maximum fire is reached.

[0113] The second limiting structure 500 is located in the first accommodating cavity 310, and the second limiting structure 500 and the first limiting structure 400 are arranged at intervals along the circumference of the first accommodating cavity 310. The second limiting structure 500 can be located at a 90° position of the valve rod structure 100.

[0114] In some embodiments, the second limiting structure 500 is integrally arranged with the valve body 300.

[0115] In some embodiments, the top of the second limiting structure 500 is provided with a relief portion 510 for avoiding the valve rod structure 100. The valve rod structure 100 moves downward through the relief portion 510, which can trigger the first switch 200.

[0116] When the gas stove is in an unignited state, the valve rod structure 100 is close to the first limiting structure 400.

[0117] Specifically, the valve rod structure 100 can abut against the side of the first limiting structure 400 facing the second limiting structure 500. Alternatively, the valve rod structure 100 can have a small spacing with the side of the first limiting structure 400 facing the second limiting structure 500. The present embodiment does not make specific limitations here.

[0118] When the user ignites, the user applies a first external force to the plug valve. Under the action of the first external force, the valve rod structure 100 moves downward to compress the elastic member and rotates toward the second limiting structure 500, so that the gas stove is in an ignited state. After the first external force is cancelled, the valve rod structure 100 moves upward under the action of the elastic member.

[0119] When the gas stove is in an ignited state, the valve rod structure 100 is located between the end of the first limiting structure 400 facing the relief portion 510 and the end of the relief portion 510 away from the first limiting structure 400. The user can start the explosive frying mode, and the user applies a second external force to the plug valve. Under the action of the second external force, the valve rod structure 100 moves downward to trigger the first switch 200.

[0120] It can be understood that the gas stove provided by the application comprises a gas stove body and a plug valve, wherein the plug valve comprises a valve rod structure 100, an elastic member, a first switch 200 and a valve body 300, a first limiting structure 400 and a second limiting structure 500. The valve body 300 is provided with a first accommodating cavity 310, the valve rod structure 100 is inserted into the first accommodating cavity 310, and the valve rod structure 100 is movably connected with the valve body 300. The second limiting structure 500 and the first limiting structure 400 are arranged along the circumference of the first accommodating cavity 310, and the top of the second limiting structure 500 is provided with a avoiding portion 510 avoiding the valve rod structure 100. The first switch 200 is configured to be in an ignition state of the gas stove, and when the valve rod structure 100 moves downward to trigger the first switch 200, the gas stove is opened in a splattering mode. When the gas stove is in an unignition state, the valve rod structure 100 is close to the first limiting structure 400. Under the action of a first external force, the valve rod structure 100 moves downward to compress the elastic member and rotates towards the second limiting structure 500, so that the gas stove is in the ignition state, and after the first external force is cancelled, the valve rod structure 100 moves upward under the action of the elastic member. When the valve rod structure 100 is located between one end of the first limiting structure 400 facing the avoiding portion 510 and one end of the avoiding portion 510 away from the first limiting structure 400, under the action of a second external force, the valve rod structure 100 moves downward to trigger the first switch 200, thereby opening the splattering mode. In this way, the valve rod structure 100 moves downward through the avoiding portion 510 and can trigger the first switch 200, thereby increasing the opening angle range of the splattering mode and improving the user experience.

[0121] Figure 8 A top view of the valve body in the plug valve provided by the embodiments of the application, Figure 9 For Figure 8 A local enlarged view at C in FIG. 5.

[0122] In some embodiments, one end of the avoiding portion 510 facing the first limiting structure 400 is flush with one end of the second limiting structure 500 facing the first limiting structure 400. In this way, the opening angle of the splattering mode is continuous, and the valve rod structure 100 can open the splattering mode when located between one end of the first limiting structure 400 facing the avoiding portion 510 and one end of the avoiding portion 510 away from the first limiting structure 400, which is conducive to improving the user experience.

[0123] In some embodiments, the central angle corresponding to the region between one end of the second limiting structure 500 facing the first limiting structure 400 and one end of the first limiting structure 400 facing the avoiding portion 510 is 90°.

[0124] In this way, the plug valve corresponds to the ignition operation of the conventional gas stove, and is convenient for user operation.

[0125] In some embodiments, the central angle corresponding to the avoidance portion 510 is greater than 20° and less than 40°.

[0126] It should be noted that statistics show users typically activate the stir-fry mode within the 60-120 degree range. Therefore, when the central angle corresponding to the avoidance part 510 is less than 20°, it is difficult to meet user needs, resulting in a poor user experience.

[0127] When the central angle corresponding to the avoidance part 510 is greater than 40°, the valve stem structure 100 rotates to the small flame state. Pressing the valve stem structure 100 starts the stir-fry mode. At this time, the instantaneous increase in heat load required by the burner is large, and the stir-fry effect is poor.

[0128] In some embodiments, the central angle corresponding to the avoidance portion 510 is 25°, 30° or 35°.

[0129] See Figure 7 and Figure 9 As shown, in some embodiments, the plug valve further includes a third limiting structure 600. The third limiting structure 600 can be used to limit the minimum firing position of the valve stem structure 100.

[0130] The third limiting structure 600 is connected to the side of the second limiting structure 500 away from the avoidance part 510.

[0131] Along the height direction, the top of the third limiting structure 600 is higher than the top of the second limiting structure 500, and the top of the first limiting structure 400 is higher than the top of the second limiting structure 500. Thus, after the valve stem structure 100 is reset under the elastic force of the elastic element, the third limiting structure 600 and the second limiting structure 500 can still effectively limit the valve stem structure 100.

[0132] It should be noted that the height direction is the axial direction of the valve stem structure 100. That is to say, the height direction is the axial direction of the valve stem 110.

[0133] In some embodiments, the third limiting structure 600 may be located at a 230° position on the valve stem structure 100.

[0134] In some embodiments, the third limiting structure 600 is integrally disposed with the valve body 300.

[0135] In some embodiments, the bottom of the first limiting structure 400 is flush with the bottom of the second limiting structure 500, and the bottom of the first limiting structure 400 is flush with the bottom of the third limiting structure 600.

[0136] Figure 10 This is a schematic diagram of the valve stem structure in the plug valve provided in the embodiments of this application. Figure 11 for Figure 10an exploded view, Figure 12 A structure diagram of a valve rod in a plug valve is provided for an embodiment of the present application.

[0137] Referring to Figures 10 to 13 As shown in the drawings, in some embodiments, the valve rod structure 100 includes a valve rod 110.

[0138] The lower part of the valve rod 110 is provided with a contact part 111. The contact part 111 is used to cooperate with the first limiting structure 400, the second limiting structure 500 and the third limiting structure 600 for limiting.

[0139] In some embodiments, the contact part 111 is integrally arranged with the valve rod 110.

[0140] When the gas stove is in an unignited state, the contact part 111 abuts against the first limiting structure 400. When the user ignites, the valve rod structure 100 is pressed and rotated. When the contact part 111 abuts against the second limiting structure 500, it indicates that the gas stove is in a maximum fire state.

[0141] Specifically, the contact part 111 can be a protrusion. During work, the side wall of the protrusion can abut against the side wall of the first limiting structure 400 facing the second limiting structure 500. The side wall of the protrusion can abut against the side wall of the second limiting structure 500 facing the first limiting structure 400. The bottom of the protrusion can abut against the bottom of the avoiding part 510.

[0142] Figure 13 A structure diagram of a valve rod structure, a first switch and a second switch in a plug valve is provided for an embodiment of the present application, Figure 14 for Figure 13 Another structure diagram.

[0143] Referring to Figure 13 and Figure 14 As shown in the drawings, in some embodiments, the valve rod structure 100 includes a pressing piece 120. The pressing piece 120 is used to trigger the first switch 200.

[0144] The pressing piece 120 is located above the first switch 200.

[0145] The pressing piece 120 is rotationally connected with the valve rod 110. The valve rod 110 drives the pressing piece 120 to move in the height direction, so that the pressing piece 120 triggers or does not trigger the first switch 200. It should be noted that the pressing piece 120 does not rotate when the valve rod 110 rotates.

[0146] Specifically, the pressing piece 120 is provided with a mounting hole, and the outer wall of the valve rod 110 is provided with a groove. The groove of the valve rod 110 is correspondingly mounted with the mounting hole of the pressing piece 120, and the pressing piece 120 can be clamped in the groove of the valve rod 110 through a fixing piece. For example, a torsion spring is used for limiting. Moreover, the outer wall of the valve rod 110 is in clearance fit with the mounting hole of the pressing piece 120, so that the valve rod 110 can rotate relative to the pressing piece 120.

[0147] In some embodiments, the first switch 200 is a micro switch. Alternatively, the first switch 200 can be a proximity switch.

[0148] It can be understood that the angle of the pressing piece 120 relative to the first switch 200 remains unchanged, and the pressing piece 120 is moved downward by the valve rod 110 to trigger the stir-frying mode in a pressing manner. The movement of the pressing piece 120 is single, which is beneficial to improve the reliability of the pressing piece 120 triggering the first switch 200.

[0149] In some embodiments, when the gas stove is in an unignited state, the pressing piece 120 has a first spacing with the first switch 200. The size of the avoiding part 510 along the height direction is greater than the first spacing. In this way, it is beneficial to ensure that the valve rod structure 100 can trigger the first switch 200.

[0150] It should be noted that the first spacing is the minimum distance required for the pressing piece 120 to move downward to trigger the first switch 200. The size of the avoiding part 510 along the height direction is the distance from the bottom to the top of the avoiding part 510. The top of the avoiding part 510 is flush with the second limiting structure 500.

[0151] For example, the pressing piece 120 is placed 2mm above the first switch 200, and the first switch 200 will be triggered when the pressing piece 120 is pressed downward along the axis by more than 2mm with the valve rod 110. The size of the avoiding part 510 along the height direction is greater than 2mm.

[0152] In some embodiments, the valve rod structure 100 further comprises a valve core 150, and the valve core 150 is provided with a cut groove, and the contact part 111 is inserted in the cut groove, and the valve rod 110 drives the valve core 150 to rotate.

[0153] In some embodiments, an elastic member is arranged in the valve core, and the elastic member is connected with the valve rod 110 and the valve core 150.

[0154] Referring to Figure 13 and Figure 14 It is shown that, in some embodiments, the valve rod structure 100 further comprises a pressing piece 130.

[0155] Among them, the pressing piece 130 is connected with the valve rod 110, the valve rod 110 drives the pressing piece 130 to rotate, and the valve rod 110 drives the pressing piece 130 to move.

[0156] In some embodiments, the plug valve further comprises a second switch 700.

[0157] When the gas stove is in an unignited state, the dial 130 triggers the second switch 700. When the user ignites, the valve stem structure 100 is pressed and rotated, so that the valve stem structure 100 stops triggering the second switch 700. In this way, through the cooperation of the dial 130 and the second switch 700, the ignition situation can be fed back in time.

[0158] In some embodiments, the second switch 700 is a micro switch. Alternatively, the second switch 700 can be a proximity switch.

[0159] In some embodiments, the dial 130 is provided with a first connecting hole, which is a non-circular hole. For example, the first connecting hole can be a rectangular hole or a special-shaped hole, etc. The valve stem 110 is inserted in the first connecting hole, and the outer wall of the valve stem 110 can be in interference fit with the first connecting hole, so that the valve stem 110 can drive the dial 130 to rotate and can drive the dial 130 to move.

[0160] Figure 15 The structure diagram of the limiting piece in the plug valve provided by the embodiments of the present application is shown in Figure 16 The structure diagram of the valve cover in the plug valve provided by the embodiments of the present application is shown in

[0161] Referring to Figure 15 and Figure 16 In some embodiments, the valve stem structure 100 further comprises a limiting piece 140. The limiting piece 140 is used to limit the valve stem structure 100 to rotate only in the depressed state.

[0162] The limiting piece 140 is connected with the valve stem 110, the valve stem 110 drives the limiting piece 140 to rotate, the valve stem 110 drives the limiting piece 140 to move, and the limiting piece 140 is provided with a first limiting part 141.

[0163] In some embodiments, the limiting piece 140 is provided with a second connecting hole, which is a non-circular hole. For example, the second connecting hole can be a rectangular hole or a special-shaped hole, etc. The valve stem 110 is inserted in the second connecting hole, and the outer wall of the valve stem 110 can be in interference fit with the second connecting hole, so that the valve stem 110 can drive the dial 130 to rotate and can drive the dial 130 to move.

[0164] In some embodiments, the plug valve further comprises a valve cover 800.

[0165] The valve cover 800 is arranged above the valve body 300. The valve cover 800 is provided with a second accommodating cavity 810 in communication with the first accommodating cavity 310, the valve rod structure 100 is inserted into the second accommodating cavity 810, and the inner wall of the second accommodating cavity 810 is provided with a second limiting portion 820 matched with the first limiting portion 141. The first limiting portion 141 is connected with the second limiting portion 820 to limit the rotation of the valve rod 110.

[0166] The first limiting portion 141 can be a limiting groove, and the second limiting portion 820 can be a limiting protrusion. The limiting groove and the limiting protrusion match each other, so that the valve rod 110 cannot be directly rotated at 0 degrees. The valve rod 110 needs to be pressed by more than a certain stroke, so that the limiting groove is separated from the limiting protrusion, and the valve rod 110 can be rotated.

[0167] Exemplarily, the height of the first limiting portion 141 and the second limiting portion 820 is 2 mm.

[0168] Specifically, the second limiting portion 820 is arranged at the 0-degree position,

[0169] In some embodiments, the elastic member can be a spring or an elastic rubber member.

[0170] In some embodiments, one end of the elastic member in the elastic force direction is connected with the pressing piece 130, and the other end is connected with the limiting piece 140.

[0171] The working process of the gas stove will be described below:

[0172] When the user ignites, the valve rod 110 needs to be pressed to the bottom to open the electromagnetic valve in the gas stove body. The downstroke is about 3-3.5 mm. When the valve rod 110 is rotated to 90 degrees, the contact portion 111 stops rotating after touching the second limiting structure 500, and the valve rod 110 cannot continue to rotate. The valve rod 110 rebounds to the top under the action of the elastic member.

[0173] By arranging the avoiding portion 510, if the user places the cock valve in the range of 90-120 degrees at this time, the valve rod 110 can still be pressed downward by 2 mm and drive the pressing piece 120 to trigger the first switch 200, thereby starting the stir-frying mode.

[0174] Therefore, when the user normally uses the stove, from ignition to rotating the cock valve to the maximum fire 90-degree position, the normal operation is ensured, and when the cock valve is rotated to 90-120 degrees, pressing the cock valve can also trigger the stir-frying mode, thereby ensuring the pressing stir-frying experience of the user.
