Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.

Referring to the drawings of the specification 1-3, a liquid feeding pump comprises at least one sealing cavity, a stroke cam and a motor module; the sealing cavity is internally provided with two one-way pieces and a piston, the one-way pieces are distributed in the same direction, one of the one-way pieces is connected with the liquid inlet cavity, the other one-way piece is connected with the liquid outlet cavity, the motor module is connected with the stroke cam, the motor module drives the stroke cam to rotate and then drives the piston to reciprocate, and liquid in the liquid inlet cavity is pumped out through the sealing cavity of the drawing and compressing pump and is fed through the liquid outlet cavity.

Referring to the description of the drawings, fig. 4-5, a first embodiment of the present invention, in which the capsule is a single capsule structure, is shown. Referring to the attached figure 4 of the specification, when the stroke cam rotates to the lower limit position, the piston cavity moves upwards next, liquid pumping is started due to negative pressure of the stroke of the closed cavity, at the moment, the first one-way part is closed, and the second one-way part is opened, so that liquid pumping is realized. Referring to the attached figure 5 of the specification, when the stroke cam rotates to the upper limit position, the piston cavity moves downwards, liquid begins to be discharged due to negative pressure of the stroke of the sealed cavity, at the moment, the first one-way piece is opened, the second one-way piece is closed, and liquid discharging is achieved.

Referring to the description of the drawings, fig. 6-8, a second embodiment of the present invention, the capsule in this embodiment is a dual capsule configuration. The pump comprises a pump body and stroke cams, wherein the number of the pump body corresponds to that of the sealing cavities, and linkage parts are arranged between the stroke cams. Referring to the attached figure 6 of the specification, when the stroke cam of the right sealing cavity is at the lower limit position, the cam moves upwards in the limit process, the piston of the right pump body is driven by the cam to move upwards, and the liquid pumping process is started due to the negative pressure of the stroke of the sealing cavity; at the moment, the stroke cam corresponding to the left sealing cavity is at the lower limit position, then the cam moves upwards in the limit process, the piston of the left pump body starts to move downwards under the driving of the linkage piece, and the liquid discharge state is started due to the negative pressure of the stroke of the sealed cavity. Referring to the attached figure 7 of the specification, when the stroke cam of the right sealing cavity is at the upper limit position, and then the cam moves downwards in the limit process, the piston of the right pump body is driven by the cam to move downwards, and the liquid outlet process is started due to the negative pressure of the stroke of the sealing cavity; at the moment, the stroke cam corresponding to the left sealing cavity is at the upper limit position, then the cam moves downwards to the lower limit process, the piston of the left pump body is driven by the linkage piece to move downwards to start to move upwards, and the liquid pumping state is started due to the negative pressure of the stroke of the sealing cavity. Therefore, for the liquid feeding device with the double-sealed cavity structure, when one sealed cavity is in a liquid pumping state, the other sealed cavity is in a liquid discharging state. Therefore, the liquid can be continuously discharged from the liquid feeding device. For the liquid feeding device with a multi-sealing cavity structure, the linkage part is arranged between the stroke cams, so that when one sealing cavity is in a liquid pumping state, other sealing cavities are in a liquid discharging state or a liquid pumping state, and continuous liquid discharging of the liquid feeding device is guaranteed.

The stroke cam can adjust the stroke of the piston by adjusting the size so as to control the liquid outlet amount of the liquid outlet cavity during single stroke of the piston. The one-way component is duckbilled silica gel, and the piston is sealed in a lip hard sealing mode.
