Abstract
The utility model discloses a low-noise air pump. An air-splitting device is mounted on an air outlet pipe of the air pump; two outlets of the air-splitting device are connected with two air outlets of the air pump; and an air collecting trough is additionally arranged between each outlet of the air-splitting device and the corresponding air outlet of the air pump. Compared with the prior art, according to the low-noise air pump, the low-noise air pump utilizes the buffer effect of the air collecting trough, greatly decreases the speed of the air current, and further reduces the noise generated by flowing of high-pressure gas, and improves the work environment.
Description
Technical field
The utility model relates to a kind of inflator, and is especially relevant with a kind of structure of low noise air pump.
Background technique
Air pump, promptly 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 through motor comes work.The working principle of air pump is: motor running, and when bleeding, the valve of connecting vessels is washed open by the air pressure of atmosphere, and gas gets into inflator, and when in tire, inflating, valve is closed by the air pressure in the inflator again, gas has just got in the tire.Air pump has been to use atmospheric principle to inflate.
In the existing technology, the structure of air pump can be as shown in Figure 1, on the steam outlet pipe 30 of air pump 10, air devider 50 has been installed, and is used to control perhaps exhaust outlet 52 air-out down of exhaust outlet 51 air-out, and this air devider 50 is an existing technology, does not do at this and gives unnecessary details.One fen flow tube 40 also is installed on the steam outlet pipe 30, is divided on the flow tube 40 modulating valve 20 is housed, this modulating valve 20 is to be used for regulating control shunt volume size, thereby the throughput of control steam outlet pipe 30 is promptly controlled the aeration quantity size.But, this air pump in use, noise is very big, seriously causes working environment.
In view of this, the inventor improves existing air pump structure, and this case produces thus.
The model utility content
The purpose of the utility model is to provide a kind of low noise air pump, to reduce noise, improves working environment.
To achieve these goals, the technological scheme of the utility model is following:
A kind of low noise air pump has been installed air devider on the steam outlet pipe of air pump, two outlets of air devider are connected with two exhaust outlets of air pump, pneumatic trough of increase between each outlet of air devider and the exhaust outlet of corresponding air pump.
One fen flow tube also is installed on the said steam outlet pipe, is divided on the flow tube modulating valve is housed.
Said pneumatic trough is square or round, has a collection chamber and a suction port, an air outlet.
After adopting such scheme; The utility model is compared with prior art: because each outlet of air devider all pass through the exhaust outlet connection of a pneumatic trough and corresponding air pump; Utilize the buffer function of pneumatic trough; Can reduce the speed of air-flow greatly, thereby reduce the noise that high pressure draught when motion produces, improve working environment.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the overall structure schematic representation of existing technology;
Fig. 2 is the overall structure schematic representation of the utility model;
Fig. 3 is the pneumatic trough structural representation of the utility model;
Fig. 4 is the whole plan view of the utility model.
Label declaration
30 fens flow tubes 40 of steam outlet pipe
Following exhaust outlet 52 pneumatic troughs 60.
Embodiment
To shown in Figure 4, is the preferred embodiment of the utility model like Fig. 2.A kind of low noise air pump; On the steam outlet pipe 30 of air pump 10, air devider 50 has been installed; Two outlets of air devider 50 are connected with following exhaust outlet 52 with last exhaust outlet 51, the improvement of the utility model be each outlet of air devider 50 with corresponding on exhaust outlet 51 or following pneumatic trough 60 of increase between the exhaust outlet 50.Pneumatic trough 60 specifically can be round or square, has a collection chamber and a suction port, an air outlet.
Like this, utilize the buffer function of 60 pairs of high pressure draughts of pneumatic trough, can reduce the speed of air-flow greatly, thereby reduce the noise that high pressure draught when motion produces, improve working environment.
For the ease of regulating the aeration quantity size, the utility model can be installed one fen flow tube 40 again on steam outlet pipe 30, divide on the flow tube 40 modulating valve 20 is housed.Like this, change air leakage amount through modulating valve 20, control steam outlet pipe 30 tolerance, control operation is easy, and controlled quentity controlled variable is held easily.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
Claims (3)
1. low noise air pump, it is characterized in that: on the steam outlet pipe of air pump, air devider has been installed, two outlets of air devider are connected with two exhaust outlets of air pump, pneumatic trough of increase between the exhaust outlet of each outlet of air devider and corresponding air pump.
2. a kind of low noise air pump as claimed in claim 1 is characterized in that: one fen flow tube also is installed on the said steam outlet pipe, is divided on the flow tube modulating valve is housed.
