As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0030] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] See also Figures 1 to 4 As shown, the utility model discloses a universal adjustable spray can, comprising a can body 1, a nozzle body 2 and an aerosol valve 3, wherein the aerosol valve 3 is arranged in the can body 1, and the nozzle body 2 is connected to the aerosol valve 3. When the nozzle body 2 is pressed downward, the aerosol enters the nozzle body 2 from the aerosol valve 3 to achieve spraying. A guide tube 21 is provided in the nozzle body 2, and a guide channel 211 is provided in the guide tube 21, and the guide channel 211 is connected to the aerosol valve 3; an ejection channel 22 is provided on the nozzle body 2, and the ejection channel 22 is connected to the guide channel 211; and further comprising an adapter device 4 and a nozzle 5, wherein the adapter device 4 is connected to the nozzle body 2, and the nozzle 5 is connected to the adapter device 4;

[0032] The adapter 4 includes a connecting head 41, a universal ball 42 and a locking mechanism 43. The connecting head 41 is connected to the nozzle body 2. A spherical cavity 411 is provided at the end of the connecting head 41 away from the nozzle body 2. The universal ball 42 is rotatably connected in the spherical cavity 411. A connecting pipe 421 is provided at the end of the universal ball 42 away from the nozzle body 2. The nozzle 5 is sleeved on the outer wall of the connecting pipe 421. The locking mechanism 43 is passed through the connecting head 41 and abuts against the outer wall of the universal ball 42 to lock the rotation angle of the universal ball 42.

[0033] Specifically, the design of the adapter 4 allows the universal ball 42 to rotate and connect within the spherical cavity 411, achieving universal adjustment of the nozzle 5. This meets consumers' needs for all-round spraying in complex environments and effectively solves the problem of traditional nozzles having unsatisfactory spraying effects in narrow spaces, corners, or on workpieces with unusual shapes. The provision of a locking mechanism 43 locks the rotation angle of the universal ball 42, ensuring the stable direction of the nozzle 5 during the spraying process and improving the accuracy and stability of the spraying. It can be understood that the universal ball 42 seamlessly fits into the spherical cavity 411, thereby preventing leakage of aerosol when entering the universal ball 42 from the connector 41.

[0034] Furthermore, a limiting column 4111 is provided on the inner wall of the spherical cavity 411, and the outer wall of the universal ball 42 is fitted to the outer wall of the limiting column 4111, and a limiting groove 4112 is formed at the connection between the limiting column 4111 and the spherical cavity 411; a limiting block 422 is provided on the outer wall of the universal ball 42, and the shape of the limiting block 422 matches the shape of the limiting groove 4112.

[0035] Specifically, a limiting post 4111 is provided inside the spherical cavity 411, and the outer wall of the universal ball 42 is tightly fitted to the outer wall of the limiting post 4111. This design enables the limiting post 4111 to effectively guide the rotation direction of the universal ball 42, ensuring the stability and accuracy of its rotation. At the same time, the limiting groove 4112 formed at the connection between the limiting post 4111 and the spherical cavity 411, and the limiting block 422 of a shape matching that provided on the outer wall of the universal ball 42, together constitute a precise limiting mechanism, which limits the rotation range of the universal ball 42 in the spherical cavity 411 and prevents the universal ball 42 from excessively rotating, thereby ensuring that the nozzle 5 is adjusted within a certain angle range. The aerosol can smoothly pass through the nozzle body 2 and the connector 41 and enter the universal ball 42, thereby improving the safety and stability of the spray can.

[0036] In one embodiment, the outer wall of the limit block 422 is fitted to the inner wall of the spherical cavity 411, and a lubricating coating is provided between the outer wall of the limit block 422 and the inner wall of the spherical cavity 411. Specifically, the outer wall of the limit block 422 is tightly fitted to the inner wall of the spherical cavity 411. This fitting design can further enhance the stability of the limit block 422 within the spherical cavity 411, making it more stable during rotation. At the same time, the tight fit between the outer wall of the limit block 422 and the inner wall of the spherical cavity 411 ensures the sealing of the adapter 4, effectively preventing the leakage of the aerosol during transmission. A lubricating coating is provided between the outer wall of the limit block 422 and the inner wall of the spherical cavity 411, effectively reducing the friction between the limit block 422 and the inner wall of the spherical cavity 411, making the rotation of the universal ball 42 smoother, reducing the resistance during rotation, and improving the flexibility of operation. It is understood that in this embodiment, the lubricating coating is a polytetrafluoroethylene coating.

[0037] In one embodiment, the locking mechanism 43 includes a locking bolt that sequentially passes through the connector 41 and the limiting post 4111 and abuts against the outer wall of the universal ball 42 to lock the rotational direction of the universal ball 42. Specifically, the locking bolt sequentially passes through the connector 41 and the limiting post 4111 and tightly abuts against the outer wall of the universal ball 42. When tightened, the locking bolt exerts sufficient pressure on the universal ball 42 to increase the friction between it and the spherical cavity 411, thereby effectively locking the rotational direction of the universal ball 42 and securing it in the desired position.

[0038] In one embodiment, the connector 41 is provided with a first flow channel 412 and a second flow channel 413. The flow channel 211, the ejection channel 22, the first flow channel 412, the second flow channel 413, and the spherical cavity 411 are sequentially connected. Specifically, after the aerosol enters the flow channel 211 from the aerosol valve 3, it flows sequentially through the ejection channel 22, the first flow channel 412, the second flow channel 413, and finally enters the spherical cavity 411. This ensures that the aerosol can flow smoothly within the nozzle body 2 and the adapter 4, reducing airflow resistance and ensuring smooth spraying.

[0039] In one embodiment, a third flow channel 423 is provided in the universal ball 42, one end of the third flow channel 423 is connected to the second flow channel 413, and the other end is connected to the connecting pipe 421. Specifically, the aerosol flows smoothly from the second flow channel 413 into the third flow channel 423, and then enters the nozzle 5 through the connecting pipe 421, and finally achieves spraying. The nozzle body 2, the adapter 4 and the nozzle 5 cooperate with each other to form a complete aerosol flow path, ensuring the overall coordination and stability of the spray can. It can be understood that while the universal ball 42 can achieve flexible rotation, it does not affect the normal flow guidance of the aerosol, so that the nozzle 5 can still maintain a good spray effect during the process of adjusting the direction.

[0040] In one embodiment, the inner diameters of the flow channel 211, the ejection channel 22, the first flow channel 412, and the second flow channel 413 decrease in sequence. Specifically, this decreasing inner diameter design allows the aerosol to gradually increase its airflow velocity as it flows through these channels, helping to increase the spray velocity and distance, enabling the spray to more effectively cover the target area. Furthermore, the decreasing inner diameter helps maintain the stability of the aerosol during flow, reducing airflow fluctuations and blockages, thereby improving the stability and reliability of the entire spray system.

[0041] In one embodiment, the inner diameter of the connecting tube 421 is smaller than the inner diameter of the second flow channel 413. Specifically, the reduction in inner diameter increases the flow rate of the aerosol when it enters the connecting tube 421. The faster flow rate can enhance the spraying ability of the spray, allowing the aerosol to spread further, thereby expanding the coverage of the spray. It is understood that in other embodiments, the inner diameter ratio of the connecting tube 421 and the second flow channel 413 can be reasonably adjusted to better control the flow rate and pressure of the aerosol, thereby achieving precise adjustment of the spray effect to meet the needs of different application scenarios.

[0042] In one embodiment, the spray head body 2 is provided with a mounting slot 23, the inner wall of which is provided with a connecting slot 231. The outer wall of the connector 41 is provided with a connecting buckle 414, which engages with the connecting buckle 414 to securely connect the connector 41 within the mounting slot 23. Specifically, the snap-fit ​​connection between the connecting buckle 414 and the connecting slot 231 provides a secure connection, preventing the connector 41 from loosening or falling off the spray head body 2. This ensures the structural stability of the spray can and creates a good seal between the connector 41 and the spray head body 2, preventing aerosol leakage and ensuring the normal use of the spray can. Furthermore, the snap-fit ​​connection makes installation and removal of the connector 41 simple and quick, facilitating user maintenance and component replacement.

[0043] In one embodiment, the nozzle 5 is straight or angled. Specifically, the straight nozzle 5 is in the shape of a straight line, and its spray direction extends in a straight line, which is suitable for scenes that require direct and long-distance spraying. The angled nozzle 5 has a certain bending angle, and the direction and angle of the bending can be adjusted according to actual needs, so that it can better adapt to complex spraying environments, such as narrow spaces, corners or workpieces of special shapes, etc., to meet the diverse needs of users in different scenarios and increase the scope of application of the spray can. It is understandable that in this embodiment, a straight nozzle 5 or an angled nozzle 5 is preferably selected. In actual applications, the user can select the appropriate type of nozzle 5 according to the specific spraying task, thereby improving the spraying efficiency and reducing the spraying time and material waste.

[0044] In one embodiment, a liquid guide hole 212 is provided on the wall of the guide tube 21, which passes through the guide tube 21. The liquid guide hole 212 is higher than the top of the aerosol valve 3. When the nozzle body 2 is pressed downward, the liquid guide hole 212 enters the aerosol valve 3, and the aerosol passes through the liquid guide hole 212 and enters the guide channel 211 from the aerosol valve 3. Specifically, a liquid inlet pipe 6 is also provided in the tank body 1. One end of the liquid inlet pipe 6 is connected to the interior of the tank body 1, and the other end is connected to the aerosol valve 3. When the user presses the nozzle body 2 downward, the guide tube 21 will move downward accordingly, allowing the liquid guide hole 212 to enter the aerosol valve 3. At this time, the aerosol first enters the aerosol valve 3 from the tank body 1 through the liquid inlet pipe 6 and is converted into an aerosol form. Then, it enters the guide channel 211 from the aerosol valve 3 through the liquid guide hole 212, thereby ensuring the normal operation of the spray can.
