[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-14 Description of a plug valve 100 according to an embodiment of the present invention.

[0021] Reference Figures 1-8 As shown, the plug valve 100 of the first aspect of this utility model includes: a valve housing 1, a valve shaft 2, a micro switch 32, a trigger 31, and a blocking member 313. An opening 11 is provided on the outer periphery of the valve housing 1, and the valve shaft 2 is movably disposed on the valve housing 1. The micro switch 32 is disposed outside the valve housing 1, and the trigger 31 is disposed inside the valve housing 1, extending out of the valve housing 1 from the opening 11. The trigger 31 moves synchronously with the valve shaft 2 within the range defined by the opening 11, thereby triggering or moving away from the micro switch 32. The blocking member 313 is disposed at the opening 11, and moves synchronously with the valve shaft 2 to open or close the opening 11.

[0022] Specifically, the valve housing 1 mainly consists of a valve body and a valve cover 12, with an opening 11 on its outer periphery. The valve shaft 2 is movably mounted on the valve housing 1, providing both an installation position and movement space for the valve shaft 2. Furthermore, the microswitch 32 is located outside the valve housing 1, preventing it from occupying internal space and interfering with other components. When the microswitch 32 malfunctions, it or the detection circuit can be quickly replaced, eliminating the need to replace the entire plug valve 100 and extending its service life.

[0023] The trigger element 31 is disposed within the valve housing 1, thus protecting it. The trigger element 31 extends out of the valve housing 1 through the opening 11, preventing obstruction from the valve housing 1. Within the area defined by the opening 11, the trigger element 31 moves synchronously with the valve shaft 2. This allows the valve shaft 2 to move the trigger element 31 to trigger or move away from the microswitch 32. When the user briefly presses the rotary valve 100 during ignition, the opening 11 opens. Upon release, the trigger element 31 moves upward and resets synchronously with the valve shaft 2. A blocking element 313 is disposed at the opening 11 and moves synchronously with the valve shaft 2 to open or close the opening 11. When the valve shaft 2 and the trigger element 31 move synchronously, the blocking element 313 moves to the opening 11, closing it and preventing insects from entering, thus improving the sealing performance. Moreover, the trigger element 31 has a simple structure, which reduces costs.

[0024] Therefore, the blocking element 313 in the plug valve 100 blocks the opening 11, which can prevent insects from entering the opening 11, thereby playing a role in preventing insects, improving sealing, and reducing costs.

[0025] According to some embodiments of this utility model, such as Figures 6-12As shown, the plug valve 100 also includes an elastic element 9, which is disposed within the valve housing 1 and is adapted to provide a force away from the micro switch 32 to the trigger 31 and the valve shaft 2.

[0026] The elastic element 9 is disposed inside the valve housing 1, which protects the elastic element 9. The elastic element 9 is adapted to provide a force away from the micro switch 32 to the trigger 31 and the valve shaft 2. Because the elastic element 9 is elastic, it can undergo elastic deformation after being subjected to force. Thus, when the user presses the stopcock valve 100 briefly, the elastic element 9 will compress. After releasing the pressure, the elastic element 9 can provide an upward elastic force to the trigger 31 to restore its elastic deformation, thereby moving the trigger 31 and the valve shaft 2 away from the micro switch 32.

[0027] According to some embodiments of the present invention, the trigger 31 includes a first mounting part 311 and a trigger part 312. The first mounting part 311 is disposed on the valve shaft 2 and moves synchronously with the valve shaft 2. The trigger part 312 is disposed on the first mounting part 311 and extends out of the valve housing 1. The trigger part 312 is disposed opposite to the micro switch 32.

[0028] The first mounting part 311 is disposed on the valve shaft 2, thus providing a mounting position for the trigger part 312, which facilitates the installation of the trigger part 312. Since the first mounting part 311 moves synchronously with the valve shaft 2, it can drive the trigger part 312 to move.

[0029] Furthermore, the trigger part 312 extends out of the valve housing 1, which facilitates the trigger part 312 to touch the micro switch 32. Moreover, the trigger part 312 and the micro switch 32 are arranged opposite each other, which can ensure that the relative position of the trigger part 312 and the micro switch 32 is more accurate, thereby avoiding poor contact between the trigger part 312 and the micro switch 32.

[0030] According to some embodiments of this utility model, such as Figure 2 As shown, the shielding member 313 is constructed in the form of a sheet, thereby blocking the opening 11.

[0031] Among them, the sheet-like or thin plate-like shape of the shielding member 313, the shielding member 313 can be set as a metal shielding member 313, which can not only reduce the weight and achieve lightweight design, but also have a certain rigidity, thereby preventing it from deforming.

[0032] Furthermore, the shield 313 shields the opening 11, which can block it and prevent foreign objects from entering the opening 11, as well as prevent dust and oil from entering from the opening 11. This can prevent dust and oil from accumulating inside the opening 11, thus keeping the inside of the opening 11 clean.

[0033] Furthermore, the shielding member 313 is designed as a sheet, which increases its area and can completely cover the opening 11. It can also prevent gaps from forming between the shielding member 313 and the opening 11, thereby preventing foreign objects from entering.

[0034] According to some embodiments of this utility model, such as Figure 2 As shown, the shielding member 313 is integrally formed on the first mounting part 311. The shielding member 313 is bent relative to the first mounting part 311, and the included angle between the shielding member 313 and the first mounting part 311 is a right angle or an obtuse angle.

[0035] The shielding component 313 is integrally formed into the first mounting portion 311. This not only reduces the number of parts and installation steps, but also increases the strength of the shielding component 313 and the first mounting portion 311, thereby preventing deformation of the shielding component 313 and extending its service life. Furthermore, the integral forming of the shielding component 313 into the first mounting portion 311 has the advantages of being seamless and jointless, resulting in better overall rigidity and the ability to withstand frequent pressing, rotation, or impact loads.

[0036] Furthermore, the shielding member 313 is bent relative to the first mounting portion 311, which reduces the distance between the shielding member 313 and the opening 11 and makes it easier for the shielding member 313 to cover the opening 11. Moreover, the bending of the shielding member 313 relative to the first mounting portion 311 also increases the overall rigidity, thereby improving the ability to resist external impacts and deformation.

[0037] Furthermore, the angle between the blocking member 313 and the first mounting part 311 is a right angle or an obtuse angle. This allows the blocking member 313 to extend laterally without occupying the internal space of the valve body 1. When the angle between the blocking member 313 and the first mounting part 311 is a right angle, by making reasonable use of space, the blocking member 313 can vertically block the opening 11, allowing the blocking member 313 and the opening 11 to fit tightly together. This improves the sealing performance between the blocking member 313 and the opening 11, and the structure is also more stable.

[0038] When the included angle between the shielding member 313 and the first mounting part 311 is an obtuse angle, the space between the shielding member 313 and the first mounting part 311 can be increased, and the shielding member 313 can avoid other components, thereby avoiding interference between the shielding member 313 and other components.

[0039] According to some embodiments of this utility model, such as Figure 2 As shown, the first mounting part 311 includes: an annular part 3111 and a straight plate part 3112. The annular part 3111 has a shaft hole 3113, through which the valve shaft 2 passes. The straight plate part 3112 is connected to the outer periphery of the annular part 3111. The trigger part 312 and the shielding member 313 are both provided on the straight plate part 3112.

[0040] The annular portion 3111 has a shaft hole 3113, which facilitates the insertion of the valve shaft 2 and allows the valve shaft 2 to be connected and fitted with the annular portion 3111. This makes the valve shaft 2 and the annular portion 3111 a whole, and the annular portion 3111 can move synchronously with the valve shaft 2 when it moves.

[0041] Furthermore, the straight plate portion 3112 is connected to the outer periphery of the ring portion 3111. The straight plate portion 3112 extends away from the ring portion 3111, which can play a supporting and force transmission role, thereby facilitating the transmission of force to the trigger portion 312. In this way, the trigger portion 312 can press the micro switch 32 forcefully.

[0042] Furthermore, the straight plate portion 3112 can provide an installation position for the trigger portion 312 and the blocking member 313, and can further reduce the distance between the blocking member 313 and the opening 11, thereby enabling the blocking member 313 to be better adapted to the opening 11.

[0043] According to some embodiments of this utility model, such as Figure 2 As shown, the trigger portion 312 is connected to one end of the straight plate portion 3112 away from the annular portion 3111, and the trigger portion 312 extends in a direction away from the straight plate portion 3112.

[0044] The trigger part 312 is connected to the end of the straight plate part 3112 that is away from the circular part 3111. This allows the trigger part 312 to correspond to the position of the micro switch 32, making it easier for the trigger part 312 and the micro switch 32 to make contact and cooperate.

[0045] Furthermore, the trigger portion 312 extends in a direction away from the straight plate portion 3112, which facilitates the precise alignment of the trigger portion 312 with the micro switch 32 and increases the contact area between the trigger portion 312 and the micro switch 32, thereby avoiding poor contact between the trigger portion 312 and the micro switch 32.

[0046] According to some embodiments of this utility model, such as Figure 2 As shown, the first mounting portion 311 has a first notch 4, which communicates with the shaft hole 3113, and the trigger portion 312 is formed by the portion of the first mounting portion 311 corresponding to the first notch 4.

[0047] The first notch 4 is designed to avoid interference with other components and to facilitate the adjustment of the angle of the trigger part 312 relative to the first notch 4.

[0048] Furthermore, the trigger part 312 is formed from the portion of the first notch 4 corresponding to the first mounting part 311. For example, before the trigger part 312 is bent, it is located at the position of the first notch 4. When the trigger part 312 is installed, it is necessary to bend the trigger part 312 out of the first notch 4 so that the trigger part 312 can easily contact and cooperate with the micro switch 32.

[0049] According to some embodiments of this utility model, such as Figure 2 As shown, the first notch 4 is located in the middle of the width direction of the straight plate portion 3112.

[0050] The first notch 4 is located in the middle of the width of the straight plate 3112. This facilitates manufacturing and also positions the trigger part 312, preventing the trigger part 312 from deforming or becoming misaligned due to force, thereby avoiding poor contact between the trigger part 312 and the micro switch 32.

[0051] According to another embodiment of the present invention, such as Figures 9-13 As shown, the shielding member 313 includes a second mounting part 6 and a shielding part 7. The second mounting part 6 abuts against the trigger member 31, and the shielding part 7 is disposed on the second mounting part 6. The shielding part 7 is bent relative to the second mounting part 6 and is disposed at the opening 11.

[0052] The valve housing 1 provides a mounting position for the second mounting part 6, which abuts against the trigger member 31 and provides support for the trigger member 31, thereby preventing deformation of the trigger member 31. The second mounting part 6 moves synchronously with the valve shaft 2 and abuts against the first mounting part 311, providing support for the first mounting part 311. The blocking part 7 is bent relative to the second mounting part 6, which reduces the distance between the blocking part 7 and the opening 11, thus facilitating the blocking part 7 to block the opening 11.

[0053] According to some embodiments of this utility model, such as Figures 9-13 As shown, a step 10 is formed between the first mounting part 311 and the trigger part 312, the second mounting part 6 is provided with a second notch 61, and a part of the trigger part 312 is provided in the second notch 61.

[0054] A step 10 is formed between the first mounting part 311 and the trigger part 312. In this way, when the trigger part 312 contacts the micro switch 32, the first mounting part 311 can be prevented from contacting the micro switch 32, thereby avoiding poor contact between the trigger part 312 and the micro switch 32.

[0055] Furthermore, a portion of the triggering part 312 is disposed in the second notch 61, so that the second notch 61 can provide a receiving space for a portion of the triggering part 312, thereby preventing the portion of the triggering part 312 from interfering with the second mounting part 6.

[0056] According to some embodiments of this utility model, such as Figure 1 As shown, the plug valve 100 also includes: a fixing frame 5, the fixing frame 5 is installed on the valve body 1, the micro switch 32 is disposed on the fixing frame 5, the fixing frame 5 is provided with a clearance opening 51, and the blocking member 313 is disposed opposite to the clearance opening 51, so that it can be adapted to pass through the clearance opening 51 when moving.

[0057] The mounting bracket 5 is installed on the valve housing 1, providing a mounting position for the bracket 5 and facilitating its installation. The micro switch 32 is also mounted on the bracket 5, providing a mounting position for the micro switch 32 and facilitating its installation. The bracket 5 has a clearance opening 51. When the user briefly presses the stopcock valve 100 during ignition, the blocking member 313 will enter the clearance opening 51 due to the force applied. Because the blocking member 313 is positioned opposite the clearance opening 51, it allows the blocking member 313 to pass through the clearance opening 51 during movement, thus preventing interference between the blocking member 313 and the bracket 5.

[0058] Furthermore, the clearance opening 51 can guide the movement trajectory of the blocking member 313 and limit the lateral (i.e., left and right) offset of the blocking member 313, thereby ensuring that the trigger member 31 is accurately aligned with the micro switch 32, improving the triggering accuracy, and avoiding poor contact.

[0059] According to some embodiments of the present invention, the plug valve 100 further includes: a limiting member 8 and an elastic member 9. The limiting member 8 is disposed on the valve shaft 2 and is in a limiting cooperation with the trigger member 31 on one side of the trigger member 31. The elastic member 9 is disposed inside the valve housing 1 and abuts against the other side of the trigger member 31 or the blocking member 313.

[0060] The limiting element 8 is disposed on the valve shaft 2, which provides an installation position for the limiting element 8, thus facilitating its installation. The limiting element 8 engages with the trigger element 31 on one side, thereby restricting movement on one side of the trigger element 31. Furthermore, the elastic element 9 is disposed on the valve body 1, which provides protection for the elastic element 9.

[0061] Furthermore, the elastic element 9 abuts against the other side of the trigger element 31 or the blocking element 313. The elastic element 9 can limit the other side of the trigger element 31. Alternatively, the elastic element 9 abuts against the blocking element 313. The blocking element 313 can provide support for the elastic element 9, thereby facilitating the elastic deformation of the elastic element 9. The elastic element 9 can be configured as a spring.

[0062] The stove according to the second aspect of the present invention includes: the plug valve 100 of the above embodiment.
