The working principle of the essential oil pump is as follows:
and (3) liquid outlet:
action a-the squeeze ring 2 is displaced in the direction of the container (lower cap) under the force of a finger and drives the upper valve 6, its end surface contacts the piston 7 after the upper valve 6 is moved about 0.5mm, during which operation the flow hole of the lower valve 8 is separated from the inclined surface of the piston 7 and the essential oil channel is opened.
Action B: the squeezing ring 2 continues to move downwards along with the force of fingers and drives the piston 7 to move downwards until the end face of the lower valve 8 contacts two protrusions in the pump body 9, and essential oil in the pump body 9 is squeezed out of an essential oil outlet along with the channel due to space compression.
Liquid absorption:
action C: after the action B is finished, the fingers are loosened, at the moment, the squeezing ring 2 drives the upper valve 6 and the lower valve 8 to move towards the upper cover 1 under the action of the reset spring 3, and after the stroke is about 0.5mm, the lower valve 8 is in inclined surface contact with the piston 7, so that the essential oil channel is closed. The extrusion ring moves upwards along with the reset spring 3 and drives the piston 7 to move upwards until the end surface of the extrusion ring contacts with the inclined surface of the thread ring 5, and in the process, the valve ball 11 is opened against the pressure of the ball pressure spring 10 due to negative pressure generated in the pump body 9, and the essential oil in the container enters into the pump body 9 along with the pressure.
And (3) air inlet:
during the operation of the above-described action B, the piston 7 moves downward away from the screw ring 5, and at the same time the air intake passage is opened, and due to the negative pressure in the container, the outside air enters the container through the air intake passage due to the pressure to reach the balance of the air pressure in the container with the outside.
During operation C, air also enters the container through the air passage.
And (3) sealing:
in a normal state (without the action of external force), the flow hole on the lower valve 8 is in contact with the inclined surface of the piston 7, and the flow hole is closed. The top end surface of the piston 7 contacts with the inner inclined surface of the thread ring 5, so that the essential oil in the pump body 9 is sealed in the pump body 9.
Various modifications and variations of the present utility model will be apparent to those skilled in the art in light of the foregoing teachings and are intended to be included within the scope of the following claims.
