Detailed Description

The technical scheme of the utility model is further described below with reference to the specific embodiments:

as shown in fig. 1, the utility model is used as a vacuum self-priming pump, and the main structure of the vacuum self-priming pump comprises a spiral sleeve 1, a soft pump body 2, a silica gel valve plate 3 and a silica gel one-way valve 4. The spiral sleeve 1 comprises a threaded part, a connecting part and a sealing plate, wherein the threaded part is fixedly connected with the connecting part through the sealing plate, a through hole is formed in the sealing plate, and one end of the soft pump body 2 is sleeved and fixed on the outer wall of the connecting part.

As shown in fig. 3, the silica gel valve plate 3 is composed of a rotating shaft, a connecting rod and a blade, a notch is formed in the inner wall of one end, close to the spiral sleeve 1, of the soft pump body 2, the rotating shaft is arranged in the notch, the blade is arranged in the connecting portion, a square hole is formed in the connecting portion, and the blade is fixedly connected with the rotating shaft through the connecting rod penetrating through the square hole.

An opening is formed in one end, far away from the spiral sleeve 1, of the soft pump body 2, a silica gel one-way valve 4 is arranged at the opening in the soft pump body, and a straight-line-shaped notch is formed in the mouth of the silica gel one-way valve 4.

In the vacuum self-priming pump of the utility model, the spiral sleeve 1 is made of PP material, and the soft pump body 2 is made of soft PE material.

When the vacuum self-priming pump is assembled, the silica gel one-way valve 4 is combined with the soft pump body 2, the silica gel valve plate 3 is mounted on the soft pump body 2, and the spiral sleeve 1 is fixedly connected with the pump body 2. When the soft pump body 2 is pressed by hands, after the silicone valve plate 3 receives the pressure brought by the soft pump body 2, the blades are turned upwards to be abutted against the sealing plates, so that the through holes are blocked, liquid backflow is prevented, meanwhile, the linear notch is opened, and liquid in the soft pump body 2 is extruded from the linear notch of the silicone one-way valve 4; when the hand is loosened, the soft pump body 2 is restored, the blades of the silica gel valve plate 3 are turned downwards under the action of gravity, the through holes on the sealing plate are exposed, so that liquid flows into the soft pump body 2 from the spiral sleeve 1 through the through holes, and the linear notch of the silica gel one-way valve 4 is closed; by constantly squeezing the cylindrical portion of the flexible pump body 2, repeated squeezing actions of the liquid can be accomplished.

As shown in fig. 2, the inner ring of the threaded part of the spiral sleeve 1 is provided with threads matched with the product package. The product package can be a packaging bottle or a packaging bag, and the vacuum self-sucking pump is in threaded connection with the product package through a threaded part.

As shown in fig. 3, the middle part of the soft pump body 2 is cylindrical, and the shape of the opening end of the soft pump body 2 is matched with the silica gel one-way valve 4. The cylindrical part of the flexible pump body 2 is used for extruding liquid.

As shown in fig. 5, the silica gel check valve 4 is conical, the mouth of the silica gel check valve 4 is arc-shaped, and one end of the silica gel check valve 4 far away from the mouth is in sealing connection with the inner wall of the soft pump body 2. The conical shape can reduce the mouth area of the silicone check valve 4, and the arc shape of the mouth can eliminate the edge angle of the silicone check valve 4.

When the vacuum self-priming pump needs to discharge liquid in the application process, the opening of the vacuum self-priming pump is downwards arranged so that the liquid flows out, and when the liquid is discharged, the opening can be vertically downwards or obliquely downwards, but the opening cannot be upwards.
