[0013] A second ball, the second ball is opposite to the second contact part and opposite to the second channel, and the valve rod rotates, the second ball triggers the second switch through the second channel under the action of the outer wall of the valve rod;

[0014] The third ball is opposite to the third contact portion and opposite to the third channel. When the valve rod rotates, the third ball moves away from the third switch through the third channel under the action of the third switch to stop triggering the third switch.

[0015] The plug valve comprises a valve rod, a valve cover, a first switch, a second switch, a third switch, a first ball, a second ball and a third ball. The side wall of the valve rod is provided with a first contact portion, a second contact portion and a third contact portion, and the first contact portion, the second contact portion and the third contact portion are arranged at intervals. The first contact portion and the second contact portion are recessed on the outer wall of the valve rod. The valve cover is provided with a receiving cavity, and the valve cover is provided with a first channel, a second channel and a third channel which are in communication with the receiving cavity respectively. The valve rod is inserted into the receiving cavity, and the valve rod is movably connected with the valve cover. In the unignited state, the first ball is opposite to the first contact portion and opposite to the first channel, and the first ball does not trigger the first switch. The second ball is opposite to the second contact portion and opposite to the second channel, and the second ball does not trigger the second switch. The third ball is opposite to the third contact portion and opposite to the third channel, and the third ball triggers the third switch. When igniting, the user presses the valve rod downward, and the valve rod moves downward. The first ball triggers the first switch through the first channel under the action of the outer wall of the valve rod. Then the user rotates the valve rod, and the second ball triggers the second switch through the second channel under the action of the outer wall of the valve rod. After rotating by a certain angle, the third ball moves away from the third switch through the third channel under the action of the third switch, and the third ball stops triggering the third switch.

[0020] In this way, no additional processing is required for the valve rod, reducing the processing difficulty and processing cost.

[0021] In some embodiments, the third contact portion is convex on the outer wall of the valve rod.

[0022] When the valve stem is rotated to misalign the third contact portion and the third ball, the third ball moves away from the third switch through the third channel under the action of the third switch.

[0023] In this way, the detection angle of the third switch can be set.

[0024] In some embodiments, the first contact portion is arranged along a circumference of the valve stem.

[0026] In some embodiments, the first channel, the second channel, and the third channel are arranged at intervals along a circumference of the accommodating cavity.

[0027] In the height direction, the first channel and the second channel are located at different heights, and the first channel and the third channel are located at different heights.

[0028] In this way, through the misaligned arrangement of the first channel, the second channel, and the third channel, the misaligned arrangement of the first switch, the second switch, and the third switch is facilitated, thereby facilitating the saving of space and the reduction of the overall size of the plug valve.

[0029] In some embodiments, the valve stem is provided with a first limiting portion.

[0030] The valve cover 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 the rotation of the valve stem.

[0031] In this way, the first limiting portion and the second limiting portion can limit the rotation of the valve stem, and the valve stem can only be rotated in the depressed state during ignition.

[0032] In some embodiments, the first limiting portion includes a first limiting segment and a second limiting segment, and the first limiting segment and the second limiting segment are located on both sides of the valve stem in the radial direction.

[0033] The second limiting portion includes a third limiting segment and a fourth limiting segment, and the third limiting segment is matched with the first limiting segment, and the fourth limiting segment is matched with the second limiting segment.

[0034] In this way, the limiting effect can be improved.

[0035] In some embodiments, the valve cover is provided with a third limiting portion, and the third limiting portion is located on one side of the second limiting portion.

[0036] The height of the bottom of the third limiting portion is lower than the height of the bottom of the second limiting portion.

[0037] The valve stem moves downward to disengage the first limiting portion from the second limiting portion, and the third limiting portion is configured to limit the rotation direction of the valve stem.

[0038] It can be understood that by setting the third limiting portion, the valve rod can only rotate in one direction after being pressed down during ignition.

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

[0040] A gas stove body;

[0041] The plug valve is connected with the gas stove body.

[0042] In this way, the plug valve is not prone to fatigue damage, and the user's experience of using the gas stove is improved. BRIEF DESCRIPTION OF DRAWINGS

[0134] When the valve stem 100 is rotated to the second contact portion 120 opposite to the third ball 900, the third ball 900 is moved away from the third switch 600 through the third passage 230 under the action of the third switch 600.

[0135] It can be understood that the second contact portion 120 is concave to the outer wall of the valve stem 100, and the third contact portion 130 is not convex to the outer wall of the valve stem 100. When the third contact portion 130 is opposite to the third ball 900, the third contact portion 130 extrudes the third ball 900, so that the third ball 900 is in contact with the third contact portion 130. When the valve stem 100 is rotated to the second contact portion 120 opposite to the third ball 900, the second contact portion 120 provides a containing space, the third ball 900 is moved away from the third switch 600 through the third passage 230 under the action of the third switch 600, and the third ball 900 stops triggering the third switch 600.

[0136] In some embodiments, the third contact portion 130 is flush with the outer wall of the valve stem 100. In this way, no additional processing is required for the valve stem 100, reducing the processing difficulty and processing cost.

[0137] In some embodiments, the third contact portion 130 is concave to the outer wall of the valve stem 100, and the degree of concave is less than that of the second contact portion 120.

[0138] In some embodiments, the second contact portion 120 can be a cut groove.

[0139] In some embodiments, the third contact portion 130 is convex to the outer wall of the valve stem 100.

[0140] In some embodiments, the third contact portion 130 is convex to the outer wall of the valve stem 100.

[0141] For example, the third contact portion 130 corresponds to a central angle of 60°. In the initial state, the edge on one side of the third contact portion 130 is in abutment with the third ball 900, and when the valve stem 100 is rotated to more than 60°, the edge on the other side of the third contact portion 130 is out of abutment with the third ball 900. The third ball 900 stops triggering the third switch 600.

[0142] In some embodiments, the first contact portion 110 is arranged circumferentially around the valve stem 100. In this way, after the valve stem 100 rebounds, the user can rotate the valve stem 100 without triggering the first switch 400.

[0143] Specifically, the central angle corresponding to the first contact portion 110 is 360°. The first contact portion 110 may include a groove.

[0144] See Figures 1 to 3 , Figure 6 As shown, in some embodiments, the first channel 210, the second channel 220 and the third channel 230 are arranged circumferentially around the receiving cavity.

[0145] Along the height direction, the first channel 210 and the second channel 220 are located at different heights, and the first channel 210 and the third channel 230 are located at different heights.

[0146] It is understandable that the staggered arrangement of the first channel 210, the second channel 220 and the third channel 230 is conducive to the staggered arrangement of the first switch 400, the second switch 500 and the third switch 600, thereby saving space and reducing the overall size of the plug valve.

[0147] In some embodiments, the second channel 220 and the third channel 230 may be located at the same height.

[0148] See Figure 4 , Figure 5 , Figure 7 and Figure 15 As shown, in some embodiments, the valve stem 100 is provided with a first limiting portion 140.

[0149] The valve cover 200 is provided with a second limiting part 240 that matches the first limiting part 140. The first limiting part 140 is connected to the second limiting part 240 to limit the rotation of the valve stem 100.

[0150] It is understandable that the first limiting part 140 and the second limiting part 240 cooperate to restrict the rotation of the valve stem 100. During ignition, the valve stem 100 can only rotate in the depressed state.

[0151] Specifically, one of the first limiting part 140 and the second limiting part 240 can be a protrusion, and the other can be a groove that matches the protrusion.

[0152] See Figure 4 , Figure 5 and Figure 15 As shown, in some embodiments, the first limiting portion 140 includes a first limiting segment 141 and a second limiting segment 142, the first limiting segment 141 and the second limiting segment 142 being located on both sides of the valve stem 100 in the radial direction.

[0153] Referring to Figure 7 As shown, the second limiting portion 240 includes a third limiting segment 241 and a fourth limiting segment 242, the third limiting segment 241 matches the first limiting segment 141, and the fourth limiting segment 242 matches the second limiting segment 142.

[0154] In this way, the limiting effect on the valve rod 100 can be improved through the cooperation of the third limiting segment 241 and the first limiting segment 141 and the fourth limiting segment 242 and the second limiting segment 142.

[0155] Referring to Figure 7 As shown, in some embodiments, the valve cover 200 is provided with a third limiting portion 250, which is located on one side of the second limiting portion 240.

[0156] The height of the bottom of the third limiting portion 250 is lower than the height of the bottom of the second limiting portion 240.

[0157] The valve rod 100 moves downward to disengage the first limiting portion 140 from the second limiting portion 240, and the third limiting portion 250 is configured to limit the rotation direction of the valve rod 100.

[0158] It can be understood that by providing the third limiting portion 250, the valve rod 100 can only rotate in one direction after being pressed down when igniting.

[0159] The working process of the plug valve will be described below:

[0160] When the user needs to ignite, he presses the valve rod 100, and when the valve rod 100 is pressed, the first ball 700 is disengaged from the first contact portion 110 and is extruded by the outer diameter of the valve rod 100, thereby pressing the key of the first switch 400 to make it in a closed state, thereby realizing the function of ignition and other functions that need to be activated, and after the valve rod 100 rebounds, the first ball 700 is reset to the first contact portion 110 due to the elastic force of the key of the first switch 400.

[0161] After pressing the valve rod 100, the first limiting portion 140 at the bottom of the valve rod 100 is disengaged from the second limiting portion 240 of the valve cover 200, and the valve rod 100 can rotate, and after the valve rod 100 rotates, the second ball 800 is disengaged from the second contact portion 120 and is extruded by the outer diameter of the valve rod 100, thereby pressing the key of the second switch 500 to make it in a closed state, thereby realizing the function of Bluetooth linkage, timing, and other functions that need to determine that the valve rod 100 is in a working state.

[0162] When the valve stem 100 is rotated to a certain angle, the second contact part 120 arranged on the valve stem 100 is rotated to the position of the third ball 900, the third ball 900 is pushed to the second contact part 120 due to the elastic force of the third switch 600, the third switch 600 is in the open state, thereby realizing the electric control function activated by judging the rotation angle of the faucet valve.

[0163] Therefore, only through the mutual cooperation structure of the valve stem 100, the valve cover 200, the ball and the switch, the control function of the faucet valve can be realized in a simple way, the reliability is strong and the user experience is improved.
