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.

[0025] 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.

[0026] See also Figures 1 to 2 As shown, the utility model discloses a quick-spray nozzle for spraying aerosol, comprising a nozzle body 1 and an aerosol valve 2, wherein the nozzle body 1 is connected to the aerosol valve 2. When the nozzle body 1 is pressed downward, the aerosol enters the nozzle body 1 from the aerosol valve 2 to achieve spraying; the nozzle body 1 comprises a pressing cover 11 and a guide tube 12, wherein a guide channel 121 is provided in the guide tube 12, and the guide channel 121 is connected to the aerosol valve 2; the pressing cover 11 is provided with at least two ejection channels 111, and the ejection channels 111 are connected to the guide channels 121.

[0027] Specifically, in the present embodiment, a quick-spray nozzle, the pressing cover 11 is the main structure of the nozzle body 1 and is the part directly operated by the user. At least two ejection channels 111 are designed thereon, and these ejection channels 111 are connected to the guide channel 121. When the user presses the pressing cover 11 downward, the aerosol is guided from the aerosol valve 2 to the ejection channel 111 on the pressing cover 11 through the guide channel 121 in the guide tube 12, thereby realizing the ejection of the aerosol. Compared with the traditional single nozzle 13 design, the provision of multiple ejection channels 111 can eject aerosol with a larger amount and a wider range of mist through multiple nozzle 13 mist points in the same time, thereby significantly improving the spraying efficiency. At the same time, the design of multiple ejection channels 111 helps to achieve a more uniform spraying effect, reducing the uneven spraying phenomenon caused by the need for a single nozzle 13 to move continuously when spraying over a large area.

[0028] In one embodiment, three ejection channels 111 are provided on the pressing cover 11 . The three ejection channels 111 are vertically arranged at equal intervals in the pressing cover 11 . The three ejection channels 111 are all connected to the guide channel 121 .

[0029] Specifically, by synchronizing the three equally spaced vertically spaced ejection channels 111 within the push-on cap 11, vertical coverage is significantly increased, significantly improving spray efficiency compared to a single nozzle 13 design. Furthermore, the equally spaced arrangement of the three ejection channels 111 creates a more uniform and dense aerosol distribution during spraying, reducing the likelihood of overspray or missed spray, and improving spray quality.

[0030] In one embodiment, a rounded corner is provided at the connection between the ejection channel 111 and the guide channel 121 .

[0031] Specifically, at the connection between the ejection channel 111 and the guide channel 121, that is, the corner where the aerosol enters the ejection channel 111 from the guide channel 121, a rounded transition is adopted instead of a right-angle transition, so that the aerosol can flow more smoothly and quickly when passing through the connection and entering the ejection channel 111, reducing flow resistance.

[0032] In one embodiment, the three ejection channels 111 have the same aperture.

[0033] Specifically, the apertures of the plurality of spray channels 111 are equal, so that the flow rate and speed of the aerosol are approximately the same when spraying, thereby ensuring that the aerosol forms a more uniform and consistent mist distribution when spraying, thereby improving the overall spraying quality.

[0034] In one embodiment, the aperture of the ejection channel 111 is smaller than the aperture of the guide channel 121 .

[0035] Specifically, the aperture of the ejection channel 111 is smaller than the aperture of the guide channel 121. This design increases the flow velocity of the aerosol when the aerosol flows through the guide channel 121 and enters the ejection channel 111 due to the sudden decrease in the cross-section of the ejection channel 111, thereby improving the spraying capacity of the nozzle and allowing the aerosol to reach the spraying surface farther and faster.

[0036] In one embodiment, the central axis of the ejection channel 111 is perpendicular to the central axis of the guide channel 121 .

[0037] Specifically, the central axes of the ejection channel 111 and the guide channel 121 are perpendicular to each other, ensuring that the aerosol can directly and efficiently enter the ejection channel 111 after flowing through the guide channel 121 and be ejected in a vertical direction. It is understood that in actual production, the inclination angle and spacing of the ejection channel 111 can be adjusted according to different user needs to achieve spraying operations in different directions such as horizontal, vertical, or tilted, thereby adapting to different operating scenarios.

[0038] In one embodiment, a nozzle 13 is provided in one end of the ejection channel 111 close to the outer wall of the push cover 11. The nozzle 13 has an opening 131, which is connected to the ejection channel 111. The aperture of the opening 131 is smaller than the aperture of the ejection channel 111 to eject the aerosol entering the ejection channel 111.

[0039] Specifically, the aperture of opening 131 is smaller than that of ejection channel 111, allowing the aerosol to form finer, more uniform droplets during ejection, thereby improving the fineness and uniformity of the spray. Simultaneously, the sudden decrease in the cross-section of opening 131 increases the flow velocity of the aerosol, thereby enhancing the spraying capability of the nozzle and allowing the aerosol to reach the spraying surface farther and faster.

[0040] In one embodiment, the aerosol valve 2 includes a sealing cover 21, a valve chamber 22 and a liquid guide tube. The top of the sealing cover 21 is provided with a groove 211 that is larger than the size of the pressing cover 11. The sealing cover 21 is arranged on the top of the valve chamber 22 for sealing the valve chamber 22; a pressure plate 221 and a compression spring 222 are provided in the valve chamber 22. One end of the guide tube 12 is provided in the pressing cover 11, and the other end passes through the sealing cover 21 and is connected to the pressure plate 221. The compression spring 222 is provided below the pressure plate 221.

[0041] Specifically, the pressing cover 11 is arranged in the groove 211 so that the pressing cover 11 can move in the vertical direction in the groove 211. When the user presses the pressing cover 11, the pressing cover 11 transmits the pressure to the pressure plate 221 through the guide tube 12. After being subjected to pressure, the pressure plate 221 moves downward and compresses the compression spring 222. The aerosol enters the valve chamber 22 through the liquid inlet channel 231 in the liquid inlet pipe 23, and enters the guide channel 121 and the ejection channel 111 under the action of pressure and is ejected. After the pressing cover 11 is released, the compression spring 222 restores the elastic force, pushing the pressure plate 221 back to the closed state to prevent the aerosol from continuing to leak. It can be understood that one end of the liquid inlet pipe 23 is connected to the valve chamber 22, and the other end is connected to the tank body 3 that stores the aerosol, thereby ensuring that the aerosol enters the valve chamber 22 from the tank body 3.

[0042] In one embodiment, a liquid guide hole 122 is provided on the wall of the guide tube 12 and passes through the guide tube 12. The liquid guide hole 122 is higher than the top of the valve chamber 22. When the pressing cover 11 is pressed downward, the liquid guide hole 122 enters the valve chamber 22, and the aerosol enters the guide channel 121 from the valve chamber 22 through the liquid guide hole 122.

[0043] Specifically, when the push cover 11 is not pressed, the liquid guide hole 122 is located inside the sealing cover 21 and is not directly connected to the inside of the valve chamber 22. At this time, the aerosol is stored in the tank body 3 and cannot enter the diversion channel 121 through the liquid guide hole 122. When the user presses the push cover 11 downward, the diversion tube 12 moves downward, and the liquid guide hole 122 enters the valve chamber 22, so that the orifice is connected to the inside of the valve chamber 22, and the aerosol stored in the tank body 3 can enter the valve chamber 22 through the liquid inlet pipe 23, and further flow into the diversion channel 121 through the liquid guide hole 122, and finally be sprayed out through the ejection channel 111 and the nozzle 13. When the user releases the push cover 11, the compression spring 222 restores its elastic force and pushes the pressure plate 221 back to its original position. At this time, the liquid guide hole 122 is again located in the sealing cover 21, closing the channel connected to the inside of the valve chamber 22 to prevent the aerosol from continuing to flow out.

[0044] The present invention further provides an aerosol can, comprising the above-mentioned quick-spray nozzle, and also comprising a can body 3 , the aerosol valve 2 being arranged in the can body 3 , and the nozzle body 1 being connected to the aerosol valve 2 .

[0045] Specifically, the tank body 3 is used to store aerosol, and the aerosol enters the nozzle body 1 through the aerosol valve 2 and is then sprayed out. Furthermore, when the user uses the aerosol can, he presses the pressing cover 11 downward, and the pressing cover 11 transmits the pressure to the pressure plate 221 in the aerosol valve 2 through the guide tube 12, compressing the compression spring 222 and opening the liquid inlet channel 231. At the same time, the aerosol in the tank body 3 enters the valve chamber 22 through the liquid inlet pipe 23 under the action of pressure, and flows into the guide channel 121 through the liquid guide hole 122. The aerosol continues to flow in the guide channel 121, and is sprayed out after being further refined by the ejection channel 111 and the nozzle 13. When the user releases the pressing cover 11, the compression spring 222 restores the elastic force to push the pressure plate 221 back to the closed state, the liquid inlet channel 231 is closed, and the aerosol is prevented from continuing to leak.

[0046] In summary, the quick-spray nozzle and aerosol can of this embodiment, through the simultaneous operation of multiple nozzles 13 on the nozzle body 1, achieves an exponential increase in the spraying area, effectively shortening the application period, and is more suitable for large-area spraying operations. Furthermore, the multiple nozzles 13 design makes spraying more uniform, reduces overspraying or missed spraying, and improves spraying quality.
