Detailed Description
Referring to fig. 1 to 11, the utility model discloses a succinct formula micro-compression air pump, including the pump body 1, with the check valve (not show in the picture) of pump body 1 connection, set up the elasticity piece that resets (not show in the picture) in the pump body 1 and set up pump valve groove 2 on the pump body 1, the check valve is for purchasing concrete structure not detailed outward, and the tank bottom of this pump valve groove 2 is equipped with valve slot hole 3, and pump valve groove 2 passes through valve slot hole 3 and pump body 1 intercommunication, be equipped with valve block 4 that can seal valve slot hole 3 in the pump valve groove 2, and valve block 4 is connected with the tank bottom of pump valve groove 2 through the slip restriction structure. The pump body 1 is made of soft rubber and is internally provided with an elastic reset piece, the elastic reset piece is a compression spring, the pump body 1 is formed by two half shells and is welded into a whole through hot melting, when the pump body 1 is pressed by hands, the valve plate 4 is attached to the valve groove hole 3 to be sealed, and meanwhile, the gas in the pump body 1 is extruded out through the one-way valve; after the hand is loosened, the compression spring resets to support the pump body 1, the inside of the pump body is negative pressure, so that the external air squeezing valve piece 4 enters the pump body 1 from the valve groove hole 3, the external air cannot reversely enter the pump body 1 from the one-way valve, the backflow of the air which is pumped out can be avoided, and then the process is repeated, so that the air can be continuously pumped into an object which needs to be inflated. As a further design, the pump body 1 is provided with a pump plug 5 for plugging the pump valve groove 2, and when not in use, the pump plug 5 can plug the pump valve groove 2 to prevent dust or impurities from entering the pump body 1.
As shown in the figure, the slip limit structure is including setting up in the slide opening 6 of the tank bottom of pump valve groove 2 and setting up the traveller 7 on valve block 4, traveller 7 and slide opening 6 sliding fit, just be equipped with spacing cap 8 on the traveller 7 and prevent that traveller 7 from deviating from slide opening 6, valve block 4 can move along slide opening 6 to realize the function of closing valve slotted hole 3 or opening valve slotted hole 3.
As shown in the figures, the pump body 1 of the present application has two structures, one of which is as follows: the top end of the pump body 1 is recessed inwards to form a pump valve groove 2, the groove wall of the pump valve groove 2 forms a positioning column, one end of a compression spring is sleeved on the positioning column, the structure enables the pump body 1 to be small in structure and small in occupied space, and the groove wall of the pump valve groove 2 forms one end of the positioning column which can be used for positioning the compression spring, the compression spring can adopt a spring with a smaller diameter, the compression spring cannot be inclined at the pump body 1 due to limitation of the positioning column when pumping air, certainly, the pump valve groove 2 is arranged at the top end of the pump body 1, so that a notch of the pump valve groove 2 can be sealed when being pressed by hand, external air cannot enter the pump body 1, and therefore the top end of the pump body 1 is provided with a plurality of air passages 9 communicated with the pump valve groove 2, and the external air can enter the pump body 1 after entering the pump valve groove 2 through the air passages 9.
The structure of its two of the pump body 1 of this application lies in: the pump body 1 is provided with an extension part 10, the pump valve groove 2 is arranged on the extension part, and the pump valve groove 2 is communicated with the pump body 1 through a cavity inside the extension part. The principle of the structure is the same as that of the first embodiment, but the position of the pump valve spool 2 is set differently, and thus, the detailed description is omitted.
