Changes or adjustments to their relative relationships should be regarded as the scope of the implementation of the present utility model without substantially changing the technical content.

[0047] Example 1

[0048] like Figure 2 and Figure 3 As shown, this embodiment provides an aerosol can, including a bottle cap 1, a bottle body 2, a valve assembly 3 and a push-type aerosol spray head 4, the valve assembly 3 is sealed and connected to the bottle body 2, the push-type aerosol spray head 4 is sleeved on the valve assembly 3, the bottle cap 1 is covered on the push-type aerosol spray head 4, a nozzle 5 is provided on the push-type aerosol spray head 4, the nozzle 5 has a conduit 6, and an atomizing sheet is also provided at the nozzle 5, and the atomizing sheet is connected to the conduit 6. It should be noted that the push-type aerosol spray head 4 and the bottle body 2 are detachably installed, for example, the push-type aerosol spray head 4 can be installed on the valve assembly 3 by threaded sleeve connection, when the gas and liquid in the bottle body 2 are used up, the bottle body 2 and the push-type aerosol spray head 4 can be disassembled, so as to realize the flexible replacement of the bottle body 2 and extend the service life of the push-type aerosol spray head 4.

[0049] When the push-type aerosol spray head 4 is subjected to downward pressing force, the conduit 6 forms a gas-liquid channel between the valve assembly 3 and the bottle body 2. Since the atmospheric pressure in the bottle body 2 is higher than the atmospheric pressure outside the tank, the gas and liquid in the bottle body 2 are sprayed out from the nozzle 5 along the gas-liquid channel.

[0050] like Figures 4 to 7 As shown, the push-type aerosol spray head 4 includes a spray head body 40 and a shoulder sleeve assembly 41 arranged at the bottom of the spray head body 40 . The nozzle 5 is arranged on the spray head body 40 , and the nozzle 5 is connected to the conduit 6 .

[0051] The top of the nozzle body 40 is provided with a first pressing portion 42, and the side wall of the nozzle body 40 is provided with a first stopper 43, the first stopper 43 protrudes from the side wall of the nozzle body 40, and the first stopper 43 is located below the first pressing portion 42. In some examples, the first stopper 43 can also be provided on the first pressing portion 42. Figure 4 As shown, the middle part of the nozzle body 40 is provided with a first stopper 43 protruding from the nozzle body 40. The nozzle body 40 is a cylindrical structure. The first pressing portion 42 is located on the upper end surface of the cylindrical structure, and the first stopper 43 is located on the side wall of the cylindrical structure. The first pressing portion 42 also has a downwardly inclined extension portion, which protrudes from the side wall of the cylindrical structure and gradually narrows. In order to facilitate the user to press, the extension portion is flat, which is convenient for the user to press with a finger, and there is a pressing mark on the extension portion, which is convenient for the user to observe and touch the pressing mark with his hand before pressing, saving effort and convenient use.

[0052] like Figure 5 As shown, the shoulder sleeve assembly 41 is provided with a first cavity 48 that penetrates therethrough, the nozzle body 40 is arranged above the first cavity 48, the bottom of the nozzle body 40 is partially connected to the shoulder sleeve assembly 41 through a connecting piece 7, and the nozzle body 40 can move relative to the shoulder sleeve assembly 41 with the connecting piece 7 as a fulcrum.

[0053] It can be understood that the bottom end of the spray head body 40 is provided with a shoulder sleeve connecting portion 44 and a shoulder sleeve gap portion 45. The top end of the shoulder sleeve assembly 41 is provided with a spray head connecting portion 46 arranged opposite to the shoulder sleeve connecting portion 44, and a spray head gap portion 47 arranged opposite to the shoulder sleeve gap portion 45, the shoulder sleeve connecting portion 44 is connected to the spray head connecting portion 46, and there is a first gap between the shoulder sleeve gap portion 45 and the spray head gap portion 47 in the first cavity 48. When the user presses the first pressing portion 42, the spray head body is forced to move obliquely downward along the first gap in the first cavity 48 and displace, driving the conduit 6 to open the valve assembly 3 downward, so that the gas-liquid channel between the conduit 6 and the bottle body 2 is opened, and the gas and liquid are sprayed from the nozzle 5 along the conduit 6. In some examples, the spray head body 40 is arranged in the first cavity 48, the shoulder sleeve assembly 41 surrounds and wraps the spray head body 40 from the outside, and a spray hole is left on the front of the shoulder sleeve assembly 41 to facilitate the nozzle to spray outward.

[0054] The shoulder sleeve assembly 41 is provided with a second cavity 52 extending therethrough, a push-release member 49 is provided above the second cavity 52, a second stopper 51 is provided at the top of the push-release member 49, the bottom end of the push-release member 49 is fixed to the shoulder sleeve assembly 41, and the push-release member 49 can move relative to the shoulder sleeve assembly 41. A second pressing portion 50 is also provided at the top of the push-release member 49, and the second pressing portion 50 is arranged at an end away from the second stopper 51. It should be noted that pressing the second pressing portion 50 can make the push-release member 49 move in the second cavity 52 relative to the shoulder sleeve assembly 41, and the movement mode is similar to the movement mode of the nozzle body 40 relative to the shoulder sleeve assembly 41, both of which are partially connected and have a relative movement with a fulcrum.

[0055] Specifically, the second stopper 51 protrudes from the top of the shoulder assembly 41, is located near the bottom of the first stopper 43, and is disposed facing the first stopper 43. Thus, when the first pressing portion 42 is pressed, the first stopper 43 moves downward with the nozzle body 40, and when the first stopper 43 moves downward to the bottom of the second stopper 51, the first pressing portion 42 is released, and the second stopper 51 limits the first stopper 43. That is, Figure 6As shown, when the first pressing portion 42 is pressed to drive the nozzle body 40 to move obliquely downward along the first gap, the first stopper 43 is displaced obliquely downward along with the nozzle body 40. When the first stopper 43 moves below the second stopper 51, the first pressing portion 42 is released, and the second stopper 51 clamps the first stopper 43. The second stopper 51 limits the first stopper 43, so that the gas-liquid channel between the conduit 6 and the bottle body 2 remains opened, and the gas and liquid in the conduit 6 are continuously sprayed out from the nozzle 5.

[0056] When the second stopper 51 is stuck to the first stopper 43, the lower end surface of the second stopper 51 is located above the upper end surface of the first stopper 43, and the lower end surface of the second stopper 51 is in close contact with the upper end surface of the first stopper 43. Figure 6 As shown, the first stopper 43 and the second stopper 51 are engaged with each other. When the second pressing portion 50 is pressed, the pressing release member 49 is displaced obliquely downward in the second cavity 52, and the second stopper 51 is displaced obliquely upward along with the pressing release member 49, so that the first stopper 43 is disengaged from the second stopper 51, and the first stopper 43 is reset, and the gas and liquid in the conduit 6 stop being sprayed out from the nozzle 5.

[0057] It can be understood that the nozzle body 40 is a cylindrical structure, a part of the bottom end of the nozzle body 40 forms a shoulder sleeve connection part 44, and the other part forms a shoulder sleeve gap part 45, and the part where the shoulder sleeve gap part 45 is located is much larger than the part where the shoulder sleeve connection part 44 is located. In addition, at the top of the shoulder sleeve assembly 41, there is a nozzle connection part 46 corresponding to the shoulder sleeve connection part 44 and a nozzle gap part 47 corresponding to the shoulder sleeve gap part 45. An arc-shaped first gap is formed between the shoulder sleeve gap part 45 and the nozzle gap part 47. When the nozzle body 40 moves downward, the arc-shaped first gap provides space for the nozzle body 40 to move downward. According to the same mechanical structure principle, the structure of the bottom of the press release member 49 is the same as the structure of the bottom end of the nozzle body 40, that is, the second gap 52 provides a moving space for the downward movement of the press release member 49. It should be noted that the shapes of the first gap and the second gap are not limited in this embodiment, and only need to meet the requirements that the nozzle body 40 and the press release member 49 can move downward under pressure.

[0058] like Figure 4As shown, the first stopper 43 is a rectangular plate-shaped structure, and the lower end face of the first stopper 43 has a first arc chamfer 430 facing the side end face of the first stopper 43. The second stopper 51 is a rectangular plate-shaped structure, and the upper end face of the second stopper 51 has a second arc chamfer 510 facing the side end face of the second stopper 51. The curvature of the first arc chamfer 430 and the second arc chamfer 510 are similar, so as to reduce the friction force when the first stopper 43 and the second stopper 51 are in contact, so that when the first pressing part 42 is pressed, the first stopper 43 can smoothly slide under the second stopper 51 and be stuck by the second stopper 51. When the second pressing part 50 is pressed, the first stopper 43 can quickly slide out from under the second stopper 51, so that the nozzle body 40 can be quickly reset and stop spraying gas and liquid. In order to facilitate pressing, the second pressing part 50 has an extension portion that is the same as the first pressing part 42, and the extension portion has a pressing mark.

[0059] The nozzle body 40 is a cylindrical structure, the shoulder sleeve assembly 41 is cylindrical, and the inner diameter of the shoulder sleeve assembly 41 is larger than the inner diameter of the nozzle body 40. The center of the shoulder sleeve assembly 41 has a first cavity 48, and the nozzle body 40 can pass through the first cavity 48. The shoulder sleeve connection part 44 is connected to the nozzle connection part 46 by a connector 7, and the connector 7 is a U-shaped structure with a deep groove in the middle. The shoulder sleeve connection part 44 and the connector 7, as well as the connector 7 and the nozzle connection part 46 can be fixedly connected by screws. The connector 7 is provided on the first surface of the nozzle body 40, and the second stopper 51 is provided on the second surface of the nozzle body 40, and the first surface is opposite to the second surface. It should be noted that the first surface is the front surface where the nozzle is located, and the second surface is the back surface opposite to the first surface. The connector 7 can also be provided in other shapes, such as an arch, etc., which is not limited in this embodiment. In some examples, the shoulder sleeve connection part 44, the connection piece 7 and the nozzle connection part 46 are integrally formed, so that the nozzle body 40 and the shoulder sleeve assembly 41 are integrally formed, which is conducive to the mold opening of plastic products and facilitates large-scale production. For actual production needs, the push-type aerosol nozzle 4 can also be integrally formed as a whole, which is not limited in this embodiment.

[0060] When the aerosol can of this embodiment is used, the valve assembly 3 is sealed on the bottle body 2, so that the gas and liquid filled in the bottle body 2 are in a closed high-pressure environment, and then the push-type aerosol spray head 4 is integrally mounted on the valve assembly 3, so that the valve assembly 3 is fixed on the lower side of the shoulder sleeve assembly 41. When it is necessary to spray gas and liquid, the user gently presses the first pressing part 42, the spray head body 40 moves downward, the gas-liquid channel between the valve assembly 3 and the bottle body 2 is opened, and spraying is achieved. At this time, the first stopper 43 is located above the second stopper 51, and the user releases the first pressing part 42, the gas-liquid channel is closed, and spraying stops. When continuous spraying is required, the user needs to increase the force to press the first pressing part 42, so that the nozzle body 40 continues to move downward, and the first block 43 moves downward with the nozzle body 40, so that the first block 43 moves downward to the bottom of the second block 51 and is stuck by the second block 51, so as to achieve continuous spraying. At this time, the user can release the first pressing part 42. Since the second block 51 forms a limit on the first block 43, it blocks the first block 43 from resetting, and the aerosol can will continue to spray gas and liquid. When continuous spraying needs to be stopped, the user presses the second pressing part 50, so that the second pressing part 50 moves downward, and the second block 51 tilts upward slightly, so that the first block 43 slides out from under the second block 51 and resets, and the nozzle body 40 resets upward, and the aerosol can stops spraying gas and liquid. The aerosol can of this embodiment retains the short-time spraying function of the existing aerosol bottle after being lightly pressed, and can effectively and continuously spray, which is easy for users to accept, saves manpower, and greatly improves user experience.

[0061] Example 2

[0062] This embodiment provides an aerosol can. The difference between this embodiment and embodiment 1 is that the push release member 49 of the shoulder assembly 41 of the push-type aerosol spray head 4 is provided with a plurality of second blocks 51 at intervals above and below, and the plurality of second blocks 51 can respectively limit the first block 43 to achieve continuous spraying and different spraying effects. Figure 8 As shown, three second blocks 51 are arranged on the push release member 49, and the three second blocks 51 are arranged vertically up and down. The spacing distances between each second block 51 are the same. In some examples, the spacing distances between each second block 51 can also be set to be different according to actual needs. When the second block 51 located at the top is stuck on the first block 43, the spray of the aerosol can is in the first gear, and the same spray effect as in Example 1 is achieved. When the second block 51 located in the middle is stuck on the first block 43, the spray of the aerosol can is in the second gear, and the spray pressure of the second gear is greater than the spray pressure of the first gear. The spray distance of the aerosol can spray is greater than the spray distance in Example 1. Fig. 9As shown, when the second stopper 51 at the bottom blocks the first stopper 43, the spray of the aerosol can is at the third gear, the spray pressure at the third gear is much greater than the spray pressure at the first gear and the second gear, and the spray distance of the aerosol can spray is much greater than the spray distance in Example 1. This embodiment provides second stops 51 at different positions to achieve spraying at multiple gears, which is conducive to meeting the spraying needs of users with different intensities.

[0063] Example 3

[0064] This embodiment provides an aerosol can, such as Fig.10 As shown, the difference between this embodiment and the first embodiment is that two first blocks 43 are respectively arranged on the side of the nozzle body, and the two first blocks 43 are symmetrically arranged with the nozzle as the center. Two pressing release members 49 are respectively arranged opposite to each first block 43. When it is necessary to stop the continuous spraying, the user can press the second pressing part 50 of one of the pressing release members 49, or press the second pressing parts 50 of the two pressing release members 49 at the same time, so that the spraying can be stopped more conveniently and quickly.

[0065] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work. Therefore, any technical solution that can be obtained by a technician in the technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
