The push-type injection valve currently used in aerosol cans on the market is a non-dosing valve. When the injection valve is in a pre-pressured state, the contents of the aerosol can are always sprayed. It is traditionally used for manual dispensing of such aerosol cans. The device cannot achieve a quantitative distribution function and can only control the amount of content sprayed by pressing the injection valve for a long time, resulting in a large amount of waste of the contents of the aerosol can. Although there are some distribution devices on the market that can achieve quantitative distribution, their structures are complex. It cannot be used with existing push-type injection valves with variable amounts, and the injection volume cannot be adjusted.

The elastic injection valve has a pressing end; the pressing assembly includes a pressing wheel that can be resettled and reciprocated by an elastic member. The pressure block installed on the casing is connected to a one-way transmission structure between the pressing wheel and the pressure block. The reciprocating sliding of the pressure block includes mutually opposite pressing movements and reset movements. The one-way transmission structure is used for When the pressing block is in the pressing movement, it drives the pressing wheel to rotate in one direction, and when it is in the reset movement, the pressing wheel is stopped. A plurality of pressing parts are arranged at annular intervals around the outer periphery of the pressing wheel, and the plurality of pressing parts are arranged as Press the pressing end sequentially to cause the elastic injection valve to eject.

The beneficial effects of the present invention are: when in use, the elastic injection valve is installed on the mouth of the aerosol can. When it is necessary to spray the cleaning materials of the aerosol can quantitatively and distributedly, the pressing block is pressed. When the pressing block is pressed from the free state, During the movement, the one-way transmission structure drives the pressing wheel to rotate in one direction. The rotating pressing wheel sequentially contacts and presses the pressing end of the elastic injection valve through multiple pressing parts on the outer periphery. In this process, the elastic injection valve realizes One or more injection opening actions are to achieve quantitative distribution. When the pressing block is pressed, it will perform a reset movement back under the action of the reset elastic force of the elastic member. During this process, the pressing wheel is in a stopped state. At this time, the pressing end does not perform a pressing operation, and the elastic injection valve does not perform an injection action. That is to say, during each working cycle of the reciprocating sliding of the pressure block, the elastic injection valve can achieve one-time quantitative distribution, avoiding continuous pressing, continuous injection, and reducing Reduce the waste of cleaning materials and increase user experience.

The pressing wheel is installed on the driven shaft through a one-way bearing. When the driven shaft rotates in one direction The one-way bearing can be used to drive the pressing wheel to rotate in one direction. When the driven shaft rotates in the other direction, the pressing wheel stops under the friction of the pressing end. That is to say, the driven wheel rotates relative to the pressing wheel at this time without affecting the pressing force. The reset movement of the block causes the pressing block to reciprocate for one cycle. The pressing wheel can only be driven to rotate during the pressing movement in the front section. When people operate, they have a higher degree of control over the pressing movement of the pressing block, which is equivalent to a After pressing the pressing block, quantitative distribution can be achieved, which is not related to the pressing time. Even if the pressing block is kept pressed, the elastic injection valve will not open the injection.

The pressing part in this solution adopts an arc-shaped convex structure, and the pressing part conflicts with the pressing end through an arc-shaped contact surface. This ensures that the pressing part can push the pressing end when rotating, so that the pressing end can smoothly jump to the next The pressing part is convenient for operation and avoids jamming.

This solution also sets up a spray volume adjustment structure to adjust the spray volume. The specific method is to adjust the reciprocating sliding stroke of the pressing block, because the reciprocating sliding stroke of the pressing block is related to the rotation angle of the pressing wheel. When a large spraying volume is required, When a small injection volume is required, the reciprocating sliding stroke of the pressing block is lengthened, and when a small injection volume is required, the reciprocating sliding stroke of the pressing block is shortened.
