Abstract
The invention discloses a low-noise self air intake air compressor core. The core comprises a cylinder barrel, a piston, a power transmission component and a cover body, wherein the power transmission component drives the piston to freely slide in the cylinder barrel; the piston adopts a self air intake type, so as to ensure that gas enters the cylinder barrel from the rear part of the cylinder barrel; the cover body and the cylinder barrel are fixedly connected with each other and then form a containing cavity; the piston and the power transmission component are installed in the containing cavity; a plurality of air inlets are formed in the cover body; a drainage channel extends from the edge of the air inlet to the interior of the cover body; the drainage channel is soft and is made of elastic material. Firstly, the drainage channel arranged at the edge of the air inlet avoids noise produced by airflow vibration caused by the friction between air and the edge of the air inlet when air enters cover body from the air inlet, and secondly, the drainage channel extending to the interior of the cover body for certain distance directly guides air into the deep interior of the cover body, and avoids the effect of noise amplification of the cover body which serves as a resonator, so that the noise of an air compressor is greatly reduced.

Also occur in that and air inlet is not provided with cylinder barrel, but using the air compressor machine from the air inlet of cylinder barrel rear portion, it adopts special work
Plug and cylinder barrel cooperation, gap between piston and cylinder barrel for the gas enters inside cylinder barrel, and then piston is again in external force
The lower gas compressing in cylinder barrel of effect, makes gas enter object to be inflatable body via gas outlet.This kind of employing is from cylinder barrel rear portion
Due to there is gap between piston and cylinder barrel, air is also easily carried dust when entering air compressor machine from gap to the air compressor machine of air inlet
Enter in cylinder barrel with impurity.And noise is larger when working.
Content of the invention
The application overcomes shortcoming of the prior art, there is provided from air admission type air compressor core, it has a kind of low noise
There is dust-proof, noise less, structure is simple, sturdy and durable, long service life feature.
In order to solve above-mentioned technical problem, the application is achieved through the following technical solutions:
A kind of low noise from air admission type air compressor core, including cylinder barrel, piston, power transmission assembly and cover body, described power transmission
In described cylinder barrel slidably, described piston is from air admission type piston to piston described in Component driver, so that gas is by cylinder
The rear portion of cylinder enters in described cylinder barrel, and described cover body is affixed with described cylinder barrel and forms accommodating cavity, described piston, power transmission
Assembly is installed on described accommodating cavity, and described cover body opens up some air inlets, from the edge of described air inlet to cover body inside
It is extended with drainage channel, described drainage channel is the drainage channel being made up of soft and resilient material.
Described drainage channel is the flexible rubber hose being inserted in described air inlet.
Described flexible rubber hose one end envelopes the edge of described air inlet, described flexible rubber hose extend to the inside of cover body one section away from
From the other end of described flexible rubber hose is located inside described cover body.
One end that described flexible rubber hose envelopes described air inlet bore edges is provided with flange, and described flange limits described flexible rubber hose
Position.
Described air inlet is circular hole, and described flexible rubber hose is cylindrical flexible rubber hose.
Described cover body is provided with the fixed seat for supporting described power transmission assembly.
Described cover body is provided with some die cavities.
Compared with prior art, the beneficial effect of the application is:
A kind of low noise described herein from air admission type air compressor core, in order to avoid dust and impurity enter cylinder barrel
Interior bring harm to air compressor machine, simultaneously from reducing the consideration such as noise, cover body, cover body cover are often set outside cartridge assemblies
Live cartridge assemblies, including the part such as rear portion of power transmission assembly, piston and cylinder barrel.It is accomplished by opening up on cover body after so designing
Air inlet, in order to air compressor air intake, the cover body generation friction yet with gas during air inlet and air inlet edge makes air-flow produce
Raw vibrations, can produce very big noise, therefore extend internally from the edge of air inlet and have by the soft and resilient material system of tool
The drainage channel becoming.First, after the edge setting drainage channel of air inlet, it is to avoid air air when air inlet enters cover body
The noise that the air-flow vibrations being produced with the friction of air inlet edge are formed, secondly, the drain extending a distance into the inside of cover body is led to
Road, air is directly introduced deep in cover body, it is to avoid cover body amplifies the effect of noise as resonance chamber, therefore greatly reduces
The noise of air compressor machine, and its structure is relatively simple, easily safeguards, as long as periodic replacement flexible rubber hose, and is hardly damaged, makes
Use life-span length.

Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the application is illustrated it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the application, be not used to limit the application.
As shown in Fig. 2 a kind of low noise of the application is from air admission type air compressor core, including cylinder barrel 1, piston 2, power transmission
Assembly 3 and cover body 4.Power transmission assembly 3 drive piston 2 in cylinder barrel 1 slidably.Piston 2 is (certainly to enter from air admission type piston 2
The China that gas formula piston 2 can be cn203453007u from Authorization Notice No. apply for a patent disclosed in piston) so that gas
Enter in cylinder barrel 1 by the rear portion of cylinder barrel 1, cover body 4 is affixed with cylinder barrel 1 and forms accommodating cavity 5, piston 2, power transmission assembly
3 are installed on accommodating cavity 5.Cover body 4 not only can play the effect of protection core component but also can prevent dust and other impurities from entering vapour
In cylinder barrel.Some air inlets 6 are opened up on cover body 4, air inlet 6 is inwardly inserted with flexible rubber hose 7, flexible rubber hose 7 one end envelopes air inlet
Hole 6 edge, flexible rubber hose 7 extends a distance into the inside of cover body 4, and the other end of flexible rubber hose 7 is located inside cover body 4.Flexible rubber hose 7
