[0031] Please see Figures 1-4 An embodiment of an aerosol rubber valve provided by this utility model:

[0032] An aerosol rubber valve, comprising:

[0033] The valve body 1 has a mating interface 2 formed at its opening. A sealing cup 3 is sleeved on the outside of the mating interface 2. A valve stem 4 is provided in the inner cavity of the valve body 1. A sealing ring assembly 5 is provided at the joint between the mating interface 2 and the sealing cup 3. A rubber tube assembly 6 is detachably connected to the outside of the valve body 1.

[0034] The sealing ring assembly 5 includes a groove 501, a sealing ring 502, a positioning hole 503, a positioning rod 504, a screw 505, and a screw hole 506;

[0035] A groove 501 is formed on the inner wall of the interface 2, a sealing ring 502 is placed inside the groove 501, a positioning hole 503 is formed inside the groove 501, and a positioning rod 504 is fixedly connected to one side of the sealing cup 3; a screw 505 is set inside the positioning rod 504, and a screw hole 506 is formed inside the positioning hole 503.

[0036] The positioning hole 503 is used for the positioning rod 504 to be inserted into it, and the inner wall of the positioning hole 503 matches the outer wall of the positioning rod 504. The above structural design allows the sealing ring 502 to be placed inside the groove 501, and then the sealing cup 3 drives the positioning rod 504 to be inserted into the positioning hole 503 from top to bottom.

[0037] The positioning hole 503 and positioning rod 504 in the engaged state are used to pre-limit the position of the sealing ring 502. The above structural design allows the sealing cup 3 to drive the positioning rod 504 to be inserted into the positioning hole 503 from top to bottom, so that the positioning hole 503 and positioning rod 504 in the engaged state pre-limit the position of the sealing ring 502.

[0038] The screw hole 506 is used for the screw 505 to make a threaded connection, and the screw 505 in the tightened state is used to lock the position of the sealing ring 502. The above structural design allows the screw 505 to be inserted into the screw hole 506 and rotated so that the screw 505 in the tightened state locks the position of the sealing ring 502. Thus, the sealing ring 502 in the installed state can improve the sealing performance at the joint between the interface 2 and the sealing cup 3.

[0039] The sealing ring 502 in the installed state is used to improve the sealing performance at the interface 2 and the sealing cup 3. The above structural design enables the sealing ring 502 in the installed state to improve the sealing performance at the interface 2 and the sealing cup 3, effectively reducing the possibility of gas leakage in the valve body 1.

[0040] In one preferred embodiment, the rubber tube assembly 6 includes a rubber tube 601, an antistatic layer 602, a corrugated layer 603, a clamp 604, and an elastic cord 605.

[0041] The rubber tube 601 is detachably connected to the valve body 1. An antistatic layer 602 is disposed on the surface of the rubber tube 601, a corrugated layer 603 is formed on the inner side of the rubber tube 601, an elastic rope 605 is disposed on one side of the rubber tube 601, and a clamp 604 is disposed at the end of the elastic rope 605. This structural design allows the clamp 604 to be fitted onto the surface of the interface 2. Since the clamp 604 is elastic, it is mounted on the surface of the interface 2 under the action of elastic potential energy. In the installed state, the clamp 604, through the elastic rope 605, provides a connection between the valve body 1 and the rubber tube 601. When the rubber tube 601 is sleeved on the outside of the valve body 1, the corrugated layer 603 can improve the stability of the rubber tube 601 sleeved on the outside of the valve body 1. Furthermore, by setting an electrostatic conductive layer 602 on the outside of the rubber tube 601, the electrostatic conductive layer 602 can conduct static electricity and improve the lightweight and flexibility of the rubber tube 601. Thus, under vacuum, when the rubber tube 601 is sleeved on the outside of the valve body 1 and the reagent is loaded into the inside of the valve body 1, the valve body 1 containing the reagent will gradually expand. Therefore, by using the rubber tube 601 as a propellant through the above structure, it is more environmentally friendly and safer, and can be carried on all public transportation.

[0042] In one preferred embodiment, the clamp 604 is used to be fitted onto the surface of the interface 2, and the clamp 604 has an elastic structure. The above structural design allows the clamp 604 to be installed on the surface of the interface 2 under the action of elastic potential energy. In the installed state, the clamp 604 connects the valve body 1 and the rubber tube 601 through the elastic rope 605.

[0043] In one preferred embodiment, the corrugated layer 603 is used to improve the stability of the rubber tube 601 sleeved on the outside of the valve body 1. The above structural design makes it possible for the corrugated layer 603 to improve the stability of the rubber tube 601 sleeved on the outside of the valve body 1.

[0044] In one preferred embodiment, the electrostatic conductive layer 602 is used to achieve electrostatic discharge and improve the lightweight and flexibility of the rubber tube 601. The above structural design enables the electrostatic conductive layer 602 to achieve electrostatic discharge and improve the lightweight and flexibility of the rubber tube 601 by providing the electrostatic conductive layer 602 on the outside of the rubber tube 601.

[0045] The working principle of this utility model is as follows: When the sealing cup 3 needs to be installed on the interface 2, the sealing ring 502 is placed inside the groove 501, and then the sealing cup 3 drives the positioning rod 504 to be inserted into the positioning hole 503 from top to bottom, so that the positioning hole 503 and the positioning rod 504 in the engagement state pre-limit the position of the sealing ring 502. Then, the screw 505 is inserted into the screw hole 506 and the screw 505 is rotated, so that the screw 505 in the tightened state locks the position of the sealing ring 502. Thus, the sealing ring 502 in the installed state can improve the sealing performance at the joint between the interface 2 and the sealing cup 3, effectively reducing the possibility of gas leakage in the valve body 1.

[0046] The clamp 604 is fitted onto the surface of the interface 2. Since the clamp 604 has an elastic structure, it is installed on the surface of the interface 2 under the action of elastic potential energy. The clamp 604 in the installed state connects the valve body 1 and the rubber tube 601 through the elastic rope 605. The rubber tube 601 is fitted onto the outside of the valve body 1. The corrugated layer 603 can improve the stability of the rubber tube 601 fitted onto the outside of the valve body 1. Furthermore, by setting the electrostatic conductive layer 602 on the outside of the rubber tube 601, the electrostatic conductive layer 602 can achieve electrostatic discharge and improve the lightweight and flexibility of the rubber tube 601. Thus, under vacuum, the rubber tube 601 is fitted onto the outside of the valve body 1, and then the reagent is filled into the inside of the valve body 1, causing the valve body 1 containing the reagent to gradually expand. The above structure selects the rubber tube 601 as the propellant, which is more environmentally friendly and safer, and can be carried on all public transportation.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
