Further, the valve core 2 is in a circular truncated cone shape, the valve core 2 is provided with an inner cavity, the small end of the valve core 2 is an air inlet end 21, and an air outlet 22 is located on the side wall of the valve core 2 and penetrates through the side wall of the valve core 2 to be communicated with the inner cavity of the valve core 2.

In some optional examples, the trigger assembly 4 further comprises a valve rod 43, the valve rod 43 is connected with the valve core 2 in a sliding way, and the first trigger piece 41 is connected with the valve rod 43; when the valve rod 43 moves toward or away from the valve body 2, the first trigger member 41 moves toward or away from the first switch 31.

Wherein, the valve rod 43 is the column setting, and first trigger 41 is connected with valve rod 43, and accessible fixed connection or mode such as detachable connect are connected. In one example, the first trigger 41 is sleeved on the valve rod 43 and a support plate 411 is integrally formed at one end facing the first switch 31, the first switch 31 is located right below the support plate 411, and in order to improve the mounting stability of the first trigger 41 and the valve rod 43 and reduce the probability of the first trigger 41 rotating around the valve rod 43, a snap spring is arranged between the first trigger 41 and the valve rod 43.

The valve rod 43 is connected with the valve core 2 in a sliding mode, and the valve rod 43 can move towards or away from the valve core 2, namely, the valve rod 43 reciprocates up and down, so that the first trigger part 41 is driven to reciprocate up and down. In one example, the valve rod 43 is disposed in a hollow center, and the valve rod 43 is sleeved on the valve core 2, so that the valve rod 43 is slidably connected with the valve core 2. In one example, an inner cavity is opened at one end of the valve core 2 facing the valve rod 43, and the valve rod 43 is positioned in the inner cavity of the valve core 2, so that the valve core 2 is connected with the valve rod 43 in a sliding manner.

In one example, the valve rod 43 is provided with a slider 431 and the cartridge 2 is provided with a slide groove 23 adapted to the slider 431. The sliding block 431 and the valve rod 43 are integrally formed, the sliding block 431 protrudes out of the side wall of the valve rod 43, the sliding groove 23 is located in the inner cavity of the valve core 2, and the sliding block 431 is located in the sliding groove 23, so that the circumferential rotation of the valve rod 43 and the valve core 2 is avoided. Further, two sliders 431 are provided, and the two sliders 431 are oppositely disposed along the center of the valve rod 43, that is, the slide groove 23 is provided in two and symmetrically disposed along the center of the valve body 2.

In one example, the cartridge 2 is provided with a slider and the stem 43 is provided with a slide groove adapted to the slider. The slider and the valve core 2 are integrally formed and located in an inner cavity of the valve core 2, the slider extends along the height direction of the valve core 2, and at the moment, the sliding groove is located on the outer wall of the valve rod 43 and extends along the height direction of the valve rod 43. The slider is located in the slide slot so as to prevent the valve rod 43 from rotating circumferentially with the valve core 2. Two or more sliding blocks and sliding grooves can be arranged.

In one example, the valve cartridge 2 is provided with a slider on the outer periphery of the valve cartridge 2, and the stem 43 is provided with an inner cavity, and the inner cavity of the stem 43 is provided with a slide groove.

In one example, the valve rod 43 is provided with a slider, the slider is provided in an inner cavity of the valve rod 43, and the slide groove is provided on an outer peripheral side of the valve body 2.

During the use, the operator pushes down the valve rod 43, so that the valve rod 43 moves towards the valve core 2, the valve rod 43 moves downwards to drive the first trigger 41 to move towards the first switch 31, and then the first trigger 41 presses the first switch 31, so that the first switch 31 is triggered.

In some optional examples, an elastic member 24 is further disposed in the valve core 2, and one end of the elastic member 24 abuts against the valve core 2 and the other end abuts against the valve stem 43. The elastic member 24 may be a spring or other elastic material, and after the operator operates the valve rod 43 to press down, the elastic member 24 compresses, and after the operator presses down, the elastic member 24 returns to move the valve rod 43 upward, so that the first trigger 41 is separated from the first switch 31, and thus, the operator does not need to operate again.

In some optional examples, a plurality of the air outlet holes 22 are provided, the air outlet holes 22 are arranged along the circumference of the valve core 2, the air outlet hole 22 located in the middle is a first hole, the aperture of the first hole is the largest, and the apertures of the air outlet holes 22 located at two sides of the first hole are gradually reduced along the direction away from the first hole.

When the gas outlet holes 22 are provided in plural, the plural gas outlet holes 22 are arranged around the circumference of the valve element 2, not in the axial direction of the valve element 2, thereby reducing the height of the valve element 2 relative to the axial arrangement along the valve element 2. And a plurality of air outlet holes 22 have different apertures, and an operator can rotate the valve core 2 to select the corresponding air outlet hole 22, so that the air outlet quantity of the air outlet 12 of the shell 1 can be selected.

The air outlet 22 located in the middle is a first hole, the aperture of the first hole is the largest, and the rest of the air outlet 22 gradually decreases in the direction away from the first hole, that is, when the operator faces the first hole to the air outlet 12, the air outlet amount of the air outlet 12 is the largest.

At this time, because the valve rod 43 and the valve core 2 can only slide along the length direction of the valve rod 43 in the radial direction, but can not rotate along the circumferential direction of the valve rod 43; that is, the operator can rotate the valve rod 43 in the circumferential direction to drive the valve core 2 to rotate, so that the valve core 2 rotates in the circumferential direction, and the suitable air outlet hole 22 can be selected to correspond to the air outlet 12 of the housing 1.

In some optional examples, the second trigger 42 is sleeved on the valve rod 43, and a protrusion 421 is provided on the outer circumference of the second trigger 42; when the valve rod 43 rotates axially around itself, the protrusion 421 moves toward or away from the second switch 32 to control the opening and closing of the second switch 32.

The second trigger 42 is sleeved on the valve rod 43, and a clamp spring may be disposed between the second trigger 42 and the valve rod 43 to improve the stability of the installation of the second trigger 42 and the valve rod 43. The second trigger 42 is disposed in a cylinder, and a protrusion 421 is integrally formed on the outer periphery of the second trigger 42. The second switch 32 is disposed on the housing 1, and an activation end of the second switch 32 faces the second activation member 42. Under the condition that the outer annular air passage does not need to be opened, the second trigger piece 42 is not in contact with the second switch 32, and when the outer annular air passage needs to be opened, the second trigger piece 42 rotates, so that the protruding portion 421 rotates towards the second switch 32, the protruding portion 421 contacts the second switch 32, the second switch 32 opens the outer annular air passage, and the outer ring of the gas stove is also on fire.

Since the second trigger member 42 is connected to the stem 43 and the stem 43 is connected to the spool 2, when the operator rotates the stem 43, the spool 2 and the second trigger member 42 are simultaneously rotated. That is, the flow rate of the air outlet 12 of the housing 1 is changed while the outer annular air passage is opened.

In some examples, the protrusion 421 may be in any shape such as a rod, a plate, and the like.

In some optional examples, the outer circumferential surface of the protruding portion 421 is provided with a cambered surface, so that the protruding portion 421 moves gradually towards or away from the second trigger member 42, which is convenient for opening the outer annular air passage, and at the same time, the flow of the air outlet 12 can be adjusted, and meanwhile, the second trigger member 42 is prevented from damaging the second switch 32 due to the arrangement of the protruding portion 421.

In some alternative examples, the end of the boss 421 remote from the valve stem 43 corresponds to the position of the first aperture. That is, when the end of the protruding portion 421 away from the valve rod 43 abuts against the second switch 32, the air outlet 12 of the housing 1 communicates with the first hole, so that the flow rate at the air outlet 12 is maximized, and at this time, there are fires at the outer ring and the center of the gas range, and the fire is maximized.

When the gas stove is used, the valve rod 43 is rotated, so that the second trigger piece 42 and the valve core 2 rotate simultaneously, the aperture of the gas outlet hole 22 corresponding to the gas outlet 12 is gradually increased in the process that the protruding portion 421 moves towards the second switch 32, when the protruding portion 421 is over against the second switch 32, the first hole is communicated with the gas outlet 12, at the moment, fire exists in the center and the outer ring of the gas stove, and the fire power of the gas stove is also maximum. The valve stem 43 can be further rotated so that the protrusion 421 is gradually spaced from the second switch 32, the diameter of the air outlet 22 corresponding to the air outlet 12 is gradually reduced, and when the protrusion 421 is separated from the second switch 32, the gas range has only fire in the center.

In some alternative examples, the plurality of outlet holes 22 are located at least half of the side wall of the spool 2. Thereby improving the adjustment range of the flow at the air outlet 12 and improving the use effect of the gas stove.

Further, the distance between two adjacent air outlet holes 22 is smaller than the caliber of the air outlet 12. When the flow at the gas outlet 12 is adjusted, the condition that the gas outlet 12 is not provided with fuel gas is avoided.

In some alternative examples, the number of the outlet holes 22 is one, the outlet holes 22 extend along the circumferential direction of the valve core 2, the width of the central portion of the outlet hole 22 is the widest, and the width of the outlet hole 22 gradually decreases toward both ends. The operator can adjust the flow rate at the air outlet 12 by rotating the valve core 2, and when the valve core is rotated to the middle of the air outlet hole 22, the flow rate at the air outlet 12 is maximum.

At this time, one end of the protruding portion 421 far away from the valve rod 43 corresponds to the middle of the air outlet 22, when the gas stove is used, the valve rod 43 is rotated, so that the second trigger member 42 and the valve core 2 rotate simultaneously, in the process that the protruding portion 421 moves towards the second switch 32, the width of the air outlet 22 corresponding to the air outlet 12 is gradually increased, when the protruding portion 421 faces the second switch 32, the middle of the air outlet 22 is communicated with the air outlet 12, at this time, fire exists in the center and the outer ring of the gas stove, and the fire of the gas stove is also the largest. The valve stem 43 may be continuously rotated so that the protrusion 421 is gradually spaced apart from the second switch 32, the width of the outlet hole 22 corresponding to the outlet 12 is gradually decreased, and when the protrusion 421 is separated from the second switch 32, the gas range has only a fire in the center.

In one example, the outlet holes 22 may be provided with one. The air outlet 22 can be a circular hole, and when the air outlet 22 is a circular hole, the air outlet 22 faces the air outlet 12, and the flow rate of the fuel gas is maximum.

In some alternative examples, the valve rod 43 is a cylinder, and the valve rod 43 is provided with a limiting plane 432 along the length direction thereof. The valve rod 43 may be a rectangular parallelepiped, and the valve rod 43 may also be a cylinder with an irregular circular cross section. The limiting plane 432 of the valve rod 43 is arranged to avoid the possibility of circumferential movement of the first trigger part 41 and the second trigger part 42 around the valve rod 43, and also to facilitate the installation of the snap spring.

In some optional examples, the plug valve further comprises a solenoid valve 5, a push rod 6 and a pushing member 7, wherein the solenoid valve 5 is arranged in the housing 1 and is communicated with the air inlet 11 of the housing 1; the push rod 6 is arranged in the shell 1, one end of the push rod 6, facing the electromagnetic valve 5, is provided with a push rod 61, and one end of the push rod 6, far away from the electromagnetic valve 5, faces the valve core 2; one end of the pushing piece 7 is connected with the bottom end of the valve rod 43, the other end of the pushing piece 7 is positioned in the inner cavity of the valve core 2, and when the pushing piece 7 moves towards or away from the push rod 6, the ejector rod 61 of the push rod 6 moves towards or away from the electromagnetic valve 5.

The push rod 61 and the push rod 6 can be integrally formed, the pushing part 7 is rod-shaped, and when the elastic part 24 is a spring, the elastic part 24 is sleeved on the pushing part 7, so that the elastic part 24 is prevented from being inclined. The push rod 6 is arranged perpendicular to the pusher 7. During the use, valve rod 43 moves towards case 2, and at this moment, impeller 7 moves towards push rod 6, and impeller 7 contacts push rod 6 and carries out the application of force to push rod 6 to make push rod 6 take place to rotate, make ejector pin 61 move towards solenoid valve 5, thereby make solenoid valve 5 open, so that the gas flows to case 2 from air inlet 11.

The following describes the technical solution provided in this embodiment with reference to a specific application scenario.

Before ignition, the air outlet 12 of the shell 1 is abutted against the side wall of the valve core 2, so that the air outlet 12 is not abutted against the air outlet hole 22. When ignition is needed, an operator presses the valve rod 43, at this time, the first trigger 41 triggers the first switch 31, the first switch 31 drives the pulser to ignite, and meanwhile, the first trigger 41 pushes the pushing part 7 to move towards the push rod 6, so that the ejector rod 61 of the push rod 6 moves towards the electromagnetic valve 5, and the electromagnetic valve 5 is opened, so that gas flows from the gas inlet 11 to the valve core 2. Then the operator rotates the valve rod 43, and the valve rod 43 rotates and drives the valve core 2 and the second trigger piece 42 to rotate simultaneously, so that the air outlet hole 22 is butted with the air outlet 12, and at the moment, the operator can continue to rotate the valve rod 43 to adjust the gas flow of the air outlet 12.
