Description

A kind of inflator

Technical field

The utility model relates to a kind of inflator, and is especially relevant with the inflator structure of convenient adjusting aeration quantity size.

Background technique

Gas-filled pump is pumping machine, inflating pump, inflator again, is the inflatable tool that applies to air bed, rubber boat, ball, automobile, motorcycle, bicycle etc.It is that running by motor comes work.The working principle of gas-filled pump: motor running, when bleeding, the valve of connecting vessels is washed open by the air pressure of atmosphere, and gas enters inflator, and when inflating in tire, valve is closed by the air pressure in the inflator again, gas has just entered in the tire.Gas-filled pump has been to use atmospheric principle to inflate.

In the prior art, the aeration quantity size of gas-filled pump is to control by the working efficiency of circuit board change motor, and control operation trouble, controlled quentity controlled variable are difficult to hold.In view of this, the inventor researches and develops, improves existing air pump structure, and this case produces thus.

The model utility content

The purpose of this utility model is to provide a kind of inflator, with the convenient control aeration quantity size of regulating.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of inflator is made up of gas-filled pump and modulating valve, and one fen flow tube is installed on the steam outlet pipe of gas-filled pump, divides the modulating valve of regulating control shunt volume size is housed on the flow tube.

Described modulating valve is made up of main body and spool; Main body has suction tude, gas outlet, spool base, and suction tude and spool base are coaxial, gas outlet and spool base vertical connection; Spool is assembled in the spool base by screw-thread fit, aligns as the adjustable side with suction tude in the inner end of spool, and it is outer as the operating end that the outer end of spool is exposed at main body; Be provided with seal ring between spool and the spool base.

The inner end of described spool forms the conical section that can insert suction tude.

After adopting such scheme, the utility model compared with prior art:

Because on the steam outlet pipe of gas-filled pump, increased the branch flow tube that modulating valve is housed, utilize this modulating valve can regulate the shunt volume size, thereby directly, control the aeration quantity size easily, and regulating voltage changes the working efficiency of motor unlike prior art, change the aeration quantity size indirectly, so the utility model control operation is easy, controlled quentity controlled variable is held easily.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment

As shown in Figure 1 to Figure 3, be preferred embodiment of the present utility model.

A kind of inflator is made up of gas-filled pump 10 and modulating valve 20, and one fen flow tube 40 is installed on the steam outlet pipe 30 of gas-filled pump 10, divide on the flow tube 40 modulating valve 20 is housed, this modulating valve 20 is used for regulating control shunt volume size, thereby the throughput of control steam outlet pipe 30 is promptly controlled the aeration quantity size.Air devider 50 also has been installed on the tracheae shown in the figure 30, has been used to control exhaust outlet 51 air-out or exhaust outlet 52 air-out down, this air devider 50 is a prior art, does not do at this and gives unnecessary details.

Modulating valve 20 structures with above-mentioned functions have a variety of, and so embodiment's modulating valve 20 is made up of main body 1 and spool 2.Main body 1 has suction tude 11, gas outlet 12, spool base 13, and suction tude 11 and spool base 13 are coaxial, gas outlet 12 and spool base 13 vertical connections, and the suction tude 11 and the gas outlet 12 of modulating valve 20 are connected on the steam outlet pipe of gas-filled pump 10.Spool 2 is assembled in the spool base 13 by screw-thread fit, align as the adjustable side with suction tude 11 in the inner end of spool 2, this embodiment further forms the conical section that can insert suction tude 11 in the inner end of spool 2, and it is outer as the operating end that the outer end of spool 2 is exposed at main body 1.Be provided with seal ring 3 between spool 2 and the spool base 13.During adjusting, screw spool 2, make the inner end of spool 2 more stretch into suction tude 11 or by withdrawing from the suction tude 11, change the ventilation cross-sectional sizes of suction tude 11, thereby change gas outlet 12 air leakage amounts, control steam outlet pipe 30 aeration quantitys, control operation is easy, and controlled quentity controlled variable is held easily.

The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
