Technical field

The present invention relates to air pump technical field, in particular to a kind of built-in air pump for aerated product.

Background technique

Air pump is the pass of various aerated products (such as airbed, inflation trampoline, inflated sofa and large-scale inflatable toys) Key member is installed in the inner side edge of the soft utricule of aerated product, can quickly be filled to aerated product using the air pump The operation such as gas, pressure maintaining and quick air releasing normal use and loses heart to realize aerated product inflating expanded and reduces spatial volume And it is conducive to the functions such as collection.

Currently, the structure of seen aerated product air pump mainly includes shell and the horse that is set in shell on the market It reaches, impeller, solenoid valve, slide, air valve.And in being respectively arranged with stomata and air drain, aforementioned air valve on shell side and bottom surface It is encapsulated on the stomata, aforementioned slide is right against the air drain.Air valve therein is connected to one end of the actuating strut of solenoid valve, and slide connects It is connected to the other end of the actuating strut of solenoid valve.Air-flow is generated by motor impeller high speed rotation, by solenoid valve control air valve pair Stomata it is on and off, solenoid valve drives slide to slide simultaneously to switch the flow direction of air-flow, and is respectively formed aerated flow and lets out Air-flow, using its aerated flow outside air to be filled in aerated product, using its discouraged stream by the air in aerated product Extraction, to realize the inflation and discouraged function of aerated product.

Although aforementioned known air pump structure is able to achieve the inflation and discouraged function of aerated product, but it is many there are still having Place to be improved is especially in the presence of structured unreasonable place.Specifically, the exhaust structure of sold air pump is multiple in the market It is miscellaneous, and bleeding trouble, exhaust is slower, influences working efficiency.

In addition, the core of air pump is exactly to pump main body, motor, shell and impeller are generally comprised, but existing impeller is using half Open type, this structure makes the space between impeller and pump case larger, after gas is come in, is easy to spin, and load is also big, influences to fill Gas or exhaust efficiency；Alternatively, to reaching same inflation or exhaust efficiency, it is necessary to more powerful motor, but this If sample, first is that power of motor is big, energy consumption increases cost；Second is that noise is big, user's use is influenced.

Therefore, existing air pump structure should be improved.

Summary of the invention

The invention mainly solves the technical problem of providing a kind of built-in electric air pumps, are changed by the structure to air pump Into, the convenient conversion of realization built-in electric air pump inflation and ventilatory state, and the pumping of air pump, exhaust efficiency are improved, it reduces Noise.

In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of built-in electric air pump is provided, Including for being connected to aerated product attachment base, be built in the aerated product shell, set on the pump main body of the shell With the driving assembly for being installed on the attachment base, the attachment base has the first port, and the pump main body has air inlet and goes out Air port；

The shell has the second port, can be realized by driving pump main body described in the driving component band to move up and down The folding of second port；

When inflation, by drive the driving component drive it is described pump main body move down and make pump main body outside with Sealing is formed between shell, under the action of pumping main body, ambient atmos pass sequentially through the first port, the inner cavity for pumping main body, air inlet Mouth and air outlet enter in aerated product；

When exhaust, by drive the driving component drive it is described pump main body move up and make pump main body outside with It is detached between shell, the gas in aerated product passes sequentially through the second port, the shell cavity that is formed and the between pump main body The discharge of one port；

The pump main body further includes shell and blade wheel structure and motor set on the inside of the shell, the air inlet The shell is set to air outlet；

The blade wheel structure includes wind-collecting cover, bottom plate and several blades, and the wind-collecting cover is located at the top of the bottom plate, institute Blade is stated between the wind-collecting cover and the bottom plate, the wind-collecting cover has air-inlet cavity, forms wind-guiding between adjacent blades Slot, gas enter the air-inlet cavity and wind guide tank by the air inlet, flow through the inside of the shell later, and through air outlet Outflow；

Definition air inlet side is top, and the motor is located at the lower section of the blade wheel structure, and the motor Motor shaft passes through the blade wheel structure and the blade wheel structure is driven to rotate.

In order to solve the above technical problems, the further technical solution that the present invention uses is: the air outlet is equipped with unidirectionally Valve, the check valve open-close type are plugged in the air outlet.

Further say there is rotary structure before the driving component and the pump main body, turn driving assembly simultaneously leads to It crosses the rotary structure and realizes moving up and down for the pump main body.

It further says, the rotary structure includes set on the pillar of the driving component and set on the upper of the pump main body The helicla flute at end, the pillar match with the helicla flute, and turn driving assembly drives the pillar and the helicla flute phase The pump main body, which moves up and down, to be realized to movement.

It further says, locking assembly is equipped at the driving component, attachment base is pushed against by the locking assembly and is realized It is relatively fixed between the driving component and the pump main body.

It further says, the locking assembly includes elastic component and pushes against part, and one end of the elastic component resists the drive It moves component and the other end resists the abutting part, while the abutting part resists the attachment base, to realize the driving group Part and it is described pump main body it is relatively fixed.

It further says, the driving component is an exposed manually operable knob, and the knob includes inner button And outer knob, the outer knob and the inner button are fixed, and the outer turn-knob is installed on the mounting base, the locking assembly Between the inner button and the outer knob.

It further says, the pump main body further includes the Ventilated seat set on the inside of shell, and the Ventilated seat is installed on institute It states between blade wheel structure and the motor；
