However, this type of energy is extremely dangerous, so we often see disasters such as gas explosions and gas leaks causing fires in the news. In addition to pipeline damage, the most common cause of these disasters is problems at the switch, such as incorrect closure or forgetting to turn off the switch, which causes continuous gas output and leakage, and ultimately leads to the aforementioned disasters, which is very costly.

[0003] Therefore, the current switch manufacturers are committed to the so-called safety switch, but ignore that most problems can be prevented as long as the switch can be turned in the correct direction to close. Therefore, the utility model is committed to launching a newly created valve body structure that can provide clear identification. Utility Model Content

[0061] Please see Figures 1 to 6As shown, the utility model provides a valve body structure with switch identification, which includes: a valve body 10, an assembly groove 101 is formed inwardly on the top end surface of the valve body 10, and a valve control component 20 is provided and a part of it is installed in the assembly groove 101, and the other part of the valve control component 20 is exposed at the notch of the assembly groove 101 and a magnetic attraction part 201 is formed on the top end surface of the valve control component 20. The valve control component 20 controls the conduction and closing of the valve body 10. In addition, the valve body 10 also has a gas inlet part 102, a gas output part 103 and a safety valve part 104. The gas inlet part 102 and the gas output part 103 The valve body 10 is connected to the valve control component 20, and the valve control component 20 controls the conduction between the gas inlet 102 and the gas output 103. The safety valve 104 is used to protect the gas from flowing inside the valve body 10 so that it can be solved immediately. A button 30 is sleeved on the exposed end of the valve control component 20 and controls the conduction and closing of the valve body 10 by the valve control component 20. The button 30 is further provided with a first assembly hole 31 and passes through the top end of the button 30 to the bottom end, and a plurality of finger grooves 32 are concavely arranged around the outer periphery of the button 30. The design of each finger groove 32 is mainly to provide users with comprehensive grip and control.

[0062] A first identification member 50 is movably disposed in the first assembly hole 31. The first identification member 50 includes an identification portion 501 and a column 502. One end of the column 502 is connected to the bottom end of the identification portion 501. The other end of the column 502 forms a magnetic attraction portion 503. There is a magnetic attraction and repulsion between the magnetic attraction portion 503 and the magnetic attraction portion 201. In addition, an elastic member 51 is set on the column 502. One end of the elastic member 51 is elastically against the identification portion 501, and the other end of the elastic member 51 is elastically against a rib 33 protruding in the first assembly hole 31. When the knob 30 rotates and approaches the valve body 10, the magnetic attraction portion 50 of the column 502 is elastically against the identification portion 501. 3 gradually approaches the magnetic attraction portion 201. When the magnetic attraction force is greater than the elastic force of the elastic member 51, the identification portion 501 of the first identification member 50 sinks into the first assembly hole 31 and compresses the elastic member 51 to store force. On the contrary, when the knob 30 rotates and moves away from the valve body 10, the magnetic attraction portion 503 of the column 502 gradually moves away from the magnetic attraction portion 201. When the magnetic attraction force is less than the stored force of the elastic member 51, the elastic member 51 rebounds against the first identification member 50, so that the identification portion 501 is exposed at the opening of the first assembly hole 31. By determining whether the identification portion 501 of the first identification member 50 is exposed at the opening of the first assembly hole 31, the valve body 10 can be quickly identified as being open or closed.

[0063] According to the above description of the utility model, for the user, before turning the button 30, he can visually check whether the current valve body 10 is open or closed, which can avoid unnecessary rotation and protect the service life of the button 30 and the valve control assembly 20. For specific users (people with limited mobility, the elderly) or installation locations with poor visibility, the user can also rotate the button 30 to make the identification portion 501 of the first identification member 50 protrude from the opening of the first assembly hole 31 or sink into the opening of the first assembly hole 31, thereby being able to feel the position of the first identification member 50 by touch, and then determine whether the current operation is open or closed. Through the above description, the user can accurately open and close the valve body 10 to ensure safety and prevent danger, and can also avoid excessive unnecessary rotation of the button 30, thereby maintaining the service life of the various parts of the utility model. In addition, when the knob 30 is fully opened (cannot rotate any further), generally speaking, the user may mistakenly judge it as closed when it cannot be rotated. Therefore, the protruding and sinking states of the first identification member 50 can easily identify the current state without misjudgment.

[0064] In addition to the main technical features described above for the utility model, other technical features and structures of the utility model are further described below. First, please see Figure 1 , Figure 4 As shown, in order to provide the user with a clearer way to judge whether the current valve body 10 is open or closed, the design of the identification portion 501 is very important. Therefore, the identification portion 501 further includes a direction indication area 501A and a text switch indication area 501B. The direction indication area 501A is arc-shaped and forms an arrow end 501C at one end. The text switch indication area 501B is connected to the side of the direction indication area 501A. The end surfaces of the direction indication area 501A and the text switch indication area 501B are both engraved with a text pattern 501D. Each text pattern 501D can be concave or convex so that the user can touch and feel to judge. In addition, the design of the arrow end 501C can provide clearer control instructions to avoid wrong control directions.

[0065] In addition, according to the structural features of the first identification member 50 in the previous paragraph, the first assembly hole 31 on the button 30 must also correspond to the first identification member 50, so the shape of the first assembly hole 31 corresponding to the direction indication area 501A and the text switch indication area 501B is further divided into an arc hole area 34 and a round hole area 35. The arc hole area 34 and the round hole area 35 are interconnected and connected, and two corresponding blocking ribs 36 are convexly provided on the inner wall surface of the connection between the arc hole area 34 and the round hole area 35. Each blocking rib 36 is embedded in the gap formed between the direction indication area 501A and the text switch indication area 501B. The setting of each blocking rib 36 can be coordinated with the shape of the direction indication area 501A and the text switch indication area 501B after connection to move up and down. In addition, it is mainly to prevent foreign matter and dirt from entering the first assembly hole 31 and affecting the action of the identification part 501. Please see Figure 4 shown.

[0066] Continuing with the above description, in order to assist the elastic member 51 in allowing the identification portion 501 of the first identification member 50 to be exposed at the opening of the first assembly hole 31 when the knob 30 is rotated away from the valve body 10, a push portion 37 is further formed in the first assembly hole 31. When the knob 30 is gradually rotated away from the valve body 10, normally the rotation of the knob 30 will drive the magnetic attraction portion 503 of the first identification member 50 to gradually move away from the magnetic attraction portion 201. When the distance reaches a certain distance, the magnetic attraction force will gradually become smaller than the stored force of the elastic member 51, and then the elastic member 51 will push the first identification member 50 upward to make the identification portion 501 exposed at the first assembly hole 31. However, when the elastic force of the elastic member 51 weakens or is lost, the push-stop portion 37 gradually approaches and abuts against the bottom surface of the identification portion 501 of the first identification member 50, and the continuous rotation of the button 30 causes the push-stop portion 37 to push the identification portion 501 (not shown in the figure, the push-stop portion 37 is used only when the elastic member 51 loses its elasticity), and cooperates with the elastic force of the elastic member 51 to push the first identification member 50 to move upward, and the identification portion 501 is partially exposed at the opening of the first assembly hole 31. In this way, the elastic member 51 can be prevented from being able to keep the first identification member 50 in an upward exposed state when the elasticity is reduced. Please refer to Figure 6 shown.

[0067] The arrangement between the knob 30 and the valve control assembly 20 is described below. Figure 2 , 3 、5、 Figure 6As shown, in order to enable the knob 30 to accurately control the valve control assembly 20 to operate and achieve the conduction and blocking of the gas inlet 102 and the gas output 103, the knob 30 is further provided with a mounting hole 38 at the portion where the valve control assembly 20 is sleeved, and a partition rib 381 is convexly provided in the mounting hole 38. The partition rib 381 separates a large diameter section 382 and a small diameter section 383 in the mounting hole 38. The circular diameter of the large diameter section 382 is larger than the circular diameter of the small diameter section 383. In addition, the large diameter section 382 and the small diameter section 383 are The sections 383 are connected to each other. The portion of the valve control component 20 exposed at the notch of the assembly groove 101 is a small-diameter section inserted and assembled in the mounting hole 38. In addition, a screw 40 is provided to pass through the button handle 30 and is locked to the valve control component 20, and the screw 40 is inserted through the large-diameter section 382 and is locked to the valve control component 20 with one end thereof. In addition, a gasket 60 is further sleeved between the screw 40 and the partition rib 381, which is mainly used to separate the direct contact between the screw 40 and the partition rib 381 to avoid damage caused by mutual friction between the two.

[0068] In addition, in order for the magnetic attraction portion 503 of the first identification member 50 and the magnetic attraction portion 201 of the valve control component 20 to be able to perform magnetic actions with each other, the magnetic attraction portion 503 of the first identification member 50 can be a magnet embedded in the column 502 or the column 502 can be made of metal. In addition, the magnetic attraction portion 201 of the valve control component 20 can be formed by a magnet embedded in the valve control component 20 and has magnetism. Therefore, no matter the entire first identification member 50 or only the column 502 is made of metal, or a magnet is embedded in the column 502 and a magnet is embedded in the valve control component 20, as long as the form that can generate magnetic attraction belongs to the scope of protection of the present invention, please see Figure 5 , Figure 6 shown.

[0069] It is worth mentioning that the present invention also has a second embodiment, see Figures 7 to 11As shown, it is different from the first embodiment in that a second assembly hole 39 is further provided on the button handle 30, and the second assembly hole 39 will penetrate from the top end to the bottom end of the button handle 30, and a second identification member 70 is movably installed in the second assembly hole 39, and the second identification member 70 includes a top identification portion 701 and a bottom support portion 702, one end of the bottom support portion 702 is connected to the top identification portion 701, and the other end of the bottom support portion 702 is normally attached to the top end surface of the valve control component 20, and the button handle 30 is rotated close to When the valve body 10 is turned on, the bottom support portion 702 of the second identification member 70 abuts against the valve control component 20 so that the top identification portion 701 gradually protrudes from the opening of the second assembly hole 39. Conversely, when the knob 30 is rotated away from the valve body 10, the top identification portion 701 of the second identification member 70 gradually sinks into the second assembly hole 39. The top identification portion 701 further distinguishes a direction marking area 703 and a switch marking area 704. The switch marking area 704 is connected to one side of the direction marking area 703, and the direction marking area One end of the switch 703 forms an arrow end 705, and the direction indicated by the arrow end 705 is opposite to that of the arrow end 501C. The second assembly hole 39 is further divided into an upper hole area 391 and a lower hole area 392 in cooperation with the direction marking area 703 and the switch marking area 704. The upper hole area 391 and the lower hole area 392 are interconnected. In addition, two corresponding ribs 393 are convexly provided on the inner wall surface at the connection between the upper hole area 391 and the lower hole area 392, and each rib 393 is embedded in the direction marking area 703 and the switch marking area 704. In the gap formed between the switch marking areas 704, a ring rib 394 is convexly provided on the inner wall of the lower hole area 392 of the second assembly hole 39, and a cutting channel 706 is cut at the bottom end of the bottom support portion 702 of the second identification member 70. After the bottom support portion 702 passes through the lower hole area 392, it abuts against the ring rib 394. The position of the bottom support portion 702 with the cutting channel 706 is compressed and deformed by the internal pressure, so that the end of the bottom support portion 702 with the cutting channel 706 passes through the ring rib 394 and then elastically returns to its original position and is confined in the lower hole area 392.

[0070] The second embodiment of the present invention can provide users with more judgment criteria for identification. Even if the elastic member 51 is not elastic and the first identification member 50 cannot be operated, at least the second identification member 70 can be kept in normal operation for identification. Finally, the top end surface of the screw 40 is further recessed to form a control groove 401. The control groove 401 can be a straight, cross or Pozi shape. It is mainly used to provide various hand tools to control the tightness of the screw 40 on the knob 30 and the valve control assembly 20, so that the knob 30 can rotate more smoothly.
