DETAILED DESCRIPTION

[0024] In order to make the utility model's purpose, technical scheme and advantage more clearly, below will combine the utility model specific embodiment and corresponding drawing to the utility model technical scheme clear, complete description. Obviously, the described embodiment is only the utility model a part embodiment, is not all embodiment. Based on the embodiment in the utility model, all other embodiments that the person of ordinary skill in the art obtains without making creative labor are within the scope of the utility model protection.

[0025] The following will be described in detail in conjunction with the drawings the technical scheme provided by each embodiment of the utility model.

[0026] The utility model embodiment provides a kind of aerosol spray head of easy locking, including tank body 1, the top of tank body 1 is provided with connecting pipeline 2, the top of connecting pipeline 2 is fixedly installed with press spray head 3, the top of press spray head 3 is fixedly installed with limit seat 4;

[0027] The top of tank body 1 is fixedly installed with bearing 5, the inner side of bearing 5 is fixedly installed with rotating shaft 6, the top of rotating shaft 6 is fixedly installed with limit block 7;

[0028] The top of limit block 7 is fixedly installed with handle 8, the inner side of limit seat 4 is provided with limit slot 9, and the top of limit seat 4 is provided with through slot 10.

[0029] Further, limit seat 4 is made of high-strength plastic or metal material, has good structural strength, can withstand the pressure generated during the pressing process of press spray head 3;Limit slot 9 is provided above limit seat, and the depth and width of limit slot 9 are accurately designed according to the size of limit block 4, to ensure that the limit block can be closely fitted in limit slot 9.

[0030] In the further preferred embodiment of the utility model, the inner side of tank body 1 is fixedly installed with seal cup 11, the upper side of seal cup 11 is provided with outer sealing washer 12, and the inner side of seal cup 11 is fixedly installed with valve body 13.

[0031] Further, in the design of the easy-to-lock aerosol spray head, the valve stem 17 plays a key role and is closely related to the spray head and the entire valve system. The main function of the valve stem 17 is to act as a transmission component for the press action of the spray head and the opening and closing of the valve. When the user presses the spray head 3, the valve stem 17 transmits the pressure to the valve structure, prompting the valve to open, so that the aerosol can be sprayed out through the spray channel under the action of the pressure in the tank. At the same time, the valve stem 17 helps to maintain the closed state of the valve when the valve is closed, preventing the aerosol from leaking.

[0032] The sealing cup 11 plays a key sealing role in the spray valve. When the spray head 3 is in an unused state, the sealing cup 11 closely fits on a specific part of the valve body 13, effectively preventing the aerosol from leaking from the valve, ensuring the sealing of the product during storage and transportation, preventing accidental spraying of the aerosol, and avoiding product waste and potential harm to the surrounding environment and users.

[0033] The outer sealing gasket 12 is installed at the connection between the spray head 3 and the aerosol tank body 1, acting as a strong "barrier". It fills the small gaps that may exist at the connection through its good elasticity and sealing performance, further enhancing the sealing of the connection between the spray head 3 and the tank body 1, ensuring that the aerosol does not escape from the connection, improving the safety performance of the product, and preventing foreign matter from entering the tank body 1, affecting the quality of the aerosol.

[0034] The valve body 13 is the core structure of the spray valve, which builds the channel framework for the flow of the aerosol. When the spray head 3 is working, the valve body 13 precisely controls the flow path of the aerosol, ensuring that the aerosol can smoothly spray out from the tank body 1 through the spray channel according to the design requirements. The rationality of its structural design directly affects the stability and uniformity of the spray, playing a decisive role in achieving good spray effect.

[0035] In further preferred embodiments of the present application, the valve body 13 is provided with a pressure relief hole 14 at the top, and the inner side of the valve body 13 is provided with a valve stem 17, and the outer side of the valve stem 17 is fixedly installed with a plurality of ribs 15, and the inner side of the valve body 13 is provided with a spring 16.

[0036] Further, the pressure relief hole 14 plays an important role in ensuring safety in the spray valve. During the spraying of the aerosol, the pressure in the tank will change, and the pressure relief hole 14 can timely adjust the pressure in the tank to prevent dangerous high pressure. When the pressure in the tank exceeds the safety threshold, part of the gas can be discharged through the pressure relief hole 14 to maintain the balance of the pressure in the tank, ensuring that the spray head 3 works within a safe pressure range, avoiding the influence of abnormal pressure on the spray effect or causing damage to the product.

[0037] The convex rib 15 is arranged on the surface of the valve body 13 or other related components, and is mainly used for enhancing the structural strength. It is like the "reinforcing steel bar" in the building, and can effectively improve the carrying capacity of the component, so that the component is not easy to be deformed or damaged when bearing the pressure generated by the pressing of the spray head 3 and the impact force when the aerosol is sprayed, thereby guaranteeing the long-term stable operation of the powder spraying valve and prolonging the service life of the spray head 3.

[0038] The spring 16 plays a role of resetting and adjusting pressure in the powder spraying valve. When the pressing spray head 3 is pressed, the spring 16 is compressed to store elastic potential energy. When the user releases the pressing spray head 3, the spring 16 releases the elastic potential energy to push the pressing spray head 3 to reset, close the valve and prevent the aerosol from continuing to spray. Meanwhile, the elastic force of the spring 16 can also adjust the pressure of the aerosol to a certain extent, so that the spraying process is more stable and uniform, and the user experience is improved.

[0039] In the further preferred embodiment of the utility model, the shape of the limiting groove 9 is circular, and the thickness of the limiting groove 9 is the same as the thickness of the limiting block 7.

[0040] Further, a rotatable rotating shaft 6 is installed above the aerosol tank body, the rotating shaft 6 is connected with the tank body 1 through a bearing 5, so that the rotating shaft 6 can rotate flexibly; the top of the rotating shaft 6 is fixed with a limiting block 7, the limiting block 7 is made of hard plastic or metal, and the shape of the limiting block 7 is matched with the limiting groove 9 and the through groove 10; when the limiting block 7 is rotated to be attached to the limiting groove 9, the pressing spray head 3 is locked and cannot be pressed down, so that the locking function of the pressing spray head 3 is realized; the surface of the limiting block 7 can be provided with anti-skid lines, so that the user can rotate the shaft body and operate the limiting block.

[0041] In the further preferred embodiment of the utility model, the shape of the through groove 10 is the same as the shape of the limiting block 7, and the outer side of the limiting block 7 is provided with an anti-skid rubber pad.

[0042] Further, the limiting seat 4 is further provided with a through groove 10 with the same size as the limiting block 7, when the limiting block 7 is rotated to the inner side of the through groove 10, the limiting block 7 can slide out from the inner side of the through groove 10, so that the staff can extrude the pressing spray head 3, and ensure that the pressing spray head 3 is in the closed state when not in use, and further improve the sealing performance of the spray head; at the same time, when the pressing spray head 3 needs to be used, the limiting block 7 only needs to be rotated to the position of the through groove 10, and the pressing spray head 3 can be normally operated, which is simple and convenient to operate.

[0043] In the further preferred embodiment of the utility model, the outer side of the limiting seat 4 is provided with a holding groove.

[0044] Further, the holding is convenient for the staff to hold the limiting seat 4, so as to facilitate the pressing control of the pressing spray head 3.
