the button is positioned above the opening and is connected with the valve core through the valve rod;
and the elastic element acts on the valve core to ensure that the valve core always keeps the trend of moving upwards.
In order to further improve the sealing property in the cavity and ensure that the cream is not polluted, a second one-way valve is further arranged at the liquid inlet and can move up and down relative to the liquid inlet so as to shield or open the liquid inlet, and the second one-way valve only allows substances in the cavity to flow into the channel.
In order to prevent the frost from being contaminated by the elastic member when flowing into the passage, the elastic member is disposed outside the passage, and the elastic member acts on the push button to keep the push button always moving upward.
In order to limit the upward movement stroke of the valve core and prevent the valve core from moving out of the opening under the action of the elastic piece, a flange which can be abutted against the upper end of the valve core is formed on the inner wall of the opening. When the valve core is abutted against the flange, the valve core cannot move upwards continuously.
In order to facilitate the arrangement of the pump seat and the positioning of the pump seat, the bottle body is provided with a step for the pump seat to be placed on, the step is the top wall of the bottle body or is formed on the inner peripheral wall of the bottle body and is arranged close to the top of the bottle body, the top of the bottle body is in threaded connection with a cover body, and the cover body enables the outer peripheral edge of the pump seat to be pressed on the step so as to position the pump seat; the cover body is provided with a liquid outlet hole communicated with the liquid outlet, and the button can be inserted on the cover body in a vertically moving mode.
In order to hide the liquid outlet hole and prevent the liquid outlet hole from being exposed and polluted, the cover is connected with a cover body through a horizontally arranged pivot, and the liquid outlet hole and the button are covered by the cover in a state that the cover is covered on the cover body.
