[0016] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1-4As shown, the double-nozzle aerosol valve described in this embodiment includes a housing 1, a pressing piece 2 fixed at one end to the housing 1, and a feed pipe 3 fixed to the pressing piece 2. The feed pipe 3 is vertically arranged, and a coaxial flow channel therein is connected to the downward pressure discharge nozzle of the aerosol can. When the pressing piece 2 is pressed, the aerosol can discharge is sprayed into the coaxial flow channel of the feed pipe 3. The feed pipe 3 is connected to an upper discharge pipe 4 and a lower discharge pipe 5. The upper discharge pipe 4 and the lower discharge pipe 5 are both horizontally arranged. A switching device is also provided on the feed pipe 3 between the upper discharge pipe 4 and the lower discharge pipe 5.

[0019] The switching device includes an adjusting plate 6 that is slidably inserted on the feed pipe 3, and a sealing gasket 7 is provided between the feed pipe 3 and the adjusting plate 6. The sealing gasket 7 is preferably made of rubber. One end of the adjusting plate 7 extends to the outside of the feed pipe 3 and a pull ring 8 is fixed to this end. A vertical flow channel 9 and an L-shaped flow channel 10 are provided on the part of the adjusting plate 6 located in the feed pipe 3. An annular flow channel 11 is provided in the lower discharge pipe 5. The annular flow channel 11 is connected to a connecting flow channel 12 and a plurality of inclined holes 13 connected to the lower discharge pipe 5. The inclined holes 13 are facing the outlet direction of the lower discharge pipe 5 and the plurality of inclined holes 13 are evenly distributed circumferentially along the cross-section of the lower discharge pipe 5. The L-shaped flow channel 10 can connect the feed pipe 3 and the connecting flow channel 12.

[0020] In order to facilitate the positioning of the adjustment piece 6 and the user's situational awareness, a card bead 14 is provided on the adjustment piece 6, and a first card slot 15 and a second card slot 16 that cooperate with the card bead 14 are provided in the feed pipe 3. When the card bead 14 is inserted into the first card slot 15, the vertical flow channel 9 is connected with the feed pipe 3. When the card bead 14 is inserted into the second card slot 16, the L-shaped flow channel 10 is connected with the feed pipe 3. In order to facilitate the card bead 14 to enter and exit the various card slots and avoid excessive resistance, a floating piece 17 is provided on the adjustment piece 6, and the card bead 14 is fixed on the floating piece 17. This can facilitate the up and down movement of the card bead 14. The floating piece 17 can be obtained by opening a horizontal slit at the tail end of the adjustment piece 6.

[0021] A feed pipe baffle 18 is provided on the housing 1 and is located obliquely above the feed pipe 3 to prevent the feed pipe 3 from swinging upward too much and thereby causing the feed pipe 3 to separate from the downward pressure discharge nozzle of the aerosol can.

[0022] The working principle of this embodiment is as follows: when the adjusting piece 6 is inserted, the pressing piece 2 is pressed down, and the material enters the feed pipe 3 and can then be supplied to the upper discharge pipe 4 and the lower discharge pipe 5 at the same time, realizing double-nozzle injection with a wide coverage; the adjusting piece 6 is pulled out to connect the L-shaped flow channel 10 with the feed pipe 3. At this time, the vertical flow channel 9 is misaligned with the feed pipe 3. When the lower pressing piece 2 is pressed down, the upper discharge pipe 3 no longer has material supply, and the material enters each inclined hole 13 through the L-shaped flow channel 10, the connecting flow channel 12 and the annular flow channel 11 and is sprayed toward the outlet of the lower discharge pipe 5, realizing pressurization and acceleration of the material in the lower discharge pipe 5, which can make the injection distance farther; compared with the prior art, this embodiment can easily switch between double-nozzle injection and single-nozzle pressurized injection to meet the diverse usage needs of users, and this embodiment is easy to adjust, has a simple and reliable structure, a long service life, and is very practical.

[0023] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
