The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 2, that the utility model is related is a kind of air pump A that charges and discharge, and this charges and discharge air pump A and is built in the air bag of inflatable product, and the inflatable product of embodiment described in the figure is air mattress B, its outer controller C that also is provided with, this controller C are provided with inflation button C1 and venting button C2.

As shown in Figure 3, it is first embodiment of the present utility model, and the described air pump A that charges and discharge mainly comprises air pump seat 1, air pump 2, scavenging air valve 3 and electromagnetic valve group 4.Wherein:

Having gas port 111 on the cover 11 of described air pump seat 1 communicates with the external world, the vent 12 that has tool one-way valve 13 on its sidewall communicates with air bag inside, be provided with a dividing plate 14 in this air pump seat 1 air pump seat 1 inside is divided into inner cavity chamber and 15 two chambers of outer chamber, and vent 12 is located in the outer chamber 15.

Described air pump 2 comprises blade 22 and motor 23, it is located in the inner cavity chamber of air pump seat 1, and in inner cavity chamber, be formed with blade cavity 21 and motor cavity 24, have inlet hole 211 and exhaust port 212 on the described dividing plate 14, wherein inlet hole 211 is positioned at motor cavity 24 places, exhaust port 212 then is positioned at blade cavity 21 and at the tangent position of blade 22, the middle axle position between blade cavity 21 and motor cavity 24 has pore 25 in addition.When motor 23 started 22 rotations of drive blade, gas was drawn in the motor cavity 24 by inlet hole 211 under the drive of blade 22, was discharged by exhaust port 212 through pore 25 then again.

Described scavenging air valve 3 is located at the outer chamber 15 of air pump seat 1, and it comprises valve seat 31, spool 32 and Returnning spring 33.These valve seat 31 inner air-

inlet cavity

311 and 312 two chambers of outlet chamber of forming, the inner of this air-inlet cavity 311 communicates with the inlet hole 211 of air pump 2, and suction port 313 and external admission mouth 314 communicate with the outer chamber 15 and the gas port 111 of air pump seat 1 respectively in having on its chamber wall; The inner of described outlet chamber 312 communicates with the exhaust port 212 of air pump 2, and air outlet 315 and outer air outlet 316 communicate with the outer chamber 15 and the gas port 111 of air pump seat 1 respectively in having on its chamber wall.Described spool 32 runs through each gas port 313,314,315,316 of valve seat 31, and it is relative with each gas port respectively to which is provided with three Sealings 321; And these spool 32 1 ends are relative with electromagnetic valve group 4, and it is relative with one-way valve 13 that the other end is provided with push rod 322.Described Returnning spring 33 is located between valve seat 31 and the spool 33.

The utility model is when inflation (shown in Fig. 2,3), push the inflation button C1 on air pump seat or the controller C, starting motor 23 makes it start working, this moment, electromagnetic valve group 4 was failure to actuate, the spool 32 of scavenging air valve 3 away from one-way valve 13, and makes the centre of spool 32 and the Sealing 321 on right side be covered in the outer air outlet 316 of outlet chamber 312 and the interior suction port 313 of air-inlet cavity 311 respectively under the effect of spring 33; At this moment, the gas of the suction military order outside that impeller 22 rotations are produced is arrived the inlet hole 211 of air pump 2 through air-inlet cavity 311 by gas port 111, because this inlet hole 211 is facing to motor cavity 24, the suction of impeller 22 will make air form vortex shape in motor cavity 24 like this, be discharged to the outlet chamber 312 of ventilation seat 3 then through the exhaust port 212 of impeller 22 tangent positions, and enter into the outer chamber 15 of air pump seat 1, pressure in this chamber is strengthened, 13 on one-way valve is opened under the effect of gas pressure, can inflate like this.

When venting (shown in Fig. 2,4), push the venting button C2 on air pump seat or the controller C, starting motor 23 is started working, the spool of electromagnetic valve group 4 moves and the spool 32 of ejection scavenging air valve 3 simultaneously, make the centre of spool 32 and the Sealing 321 in left side be covered in the outer air outlet 314 of air-inlet cavity 311 and the interior suction port 316 of outlet chamber 311 respectively, 322 ejection one-way valves 13 of the push rod on the spool 32 are opened it; At this moment, the suction military order air bag gas inside that impeller 22 rotations are produced is entered the inlet hole 211 of the air-inlet cavity 311 arrival air pumps 2 of valve seat 32 through the outer chamber 15 of air pump seat 1 by vent 12, equally, because described inlet hole 211 is facing to motor cavity 24, the suction of impeller 22 makes air form vortex shape in motor cavity 24, be discharged to the outlet chamber 312 of ventilation seat 3 then through the exhaust port 212 of impeller 22 tangent positions, be discharged to the outside by gas port 111 again, to realize the venting function.

Shown in Fig. 5,6, it is second embodiment of the present utility model for another example, and the described air pump A that charges and discharge comprises air pump seat 1, air pump 2, scavenging air valve 3 and electromagnetic valve group 4 equally.Present embodiment is all identical with above-mentioned first embodiment's most of structure and number in the figure, different is: described blade 22 is oppositely setting with respect to first embodiment, and its pore 25 is not to be arranged between blade cavity 21 and the motor cavity 24, but be arranged at the middle axle position that blade cavity 21 differs from motor cavity 24 1 sides, in addition, leave the gap between the chamber wall of the chamber wall of blade cavity 24 and air pump seat 1.When motor 23 starts 22 rotations of drive blade, gas is drawn in the motor cavity 24 by inlet hole 211 under the drive of blade 22, is passed through by the gap between blade cavity 21 chamber walls and the air pump seat 1 chamber wall again, enter into blade cavity 21 by pore 25 then, discharge by exhaust port 212 more at last.This kind structure, gas will be around whole motor cavities 24, thereby can play better radiating effect to motor.

Shown in Fig. 7,8, it is the 3rd embodiment of the present utility model, present embodiment and above-mentioned two embodiments' difference is: its air pump 2 does not resemble and is cross setting above-mentioned two embodiments, but vertically be provided with, be that the blade 22 of described air pump 2 and the axis of motor 23 are vertically, 24 of blade cavities are cross setting, and make the below of the axis of blade 22 over against inlet hole 211, exhaust port 212 then is positioned at the tangent position of blade 22, at this moment, because air-flow no longer passes through motor cavity 24, so between blade cavity 21 and the motor cavity 24 pore is set no longer also.Other structure of present embodiment is all identical with above-mentioned two embodiments with label, is repeating no more.This embodiment realizes the conversion of inflation and venting equally by the spool 32 of electromagnetic valve group 4 control scavenging air valves 3, therefore can be completely achieved the purpose of automatic electronic, but because this charges and discharge air pump when starting, air-flow is not by motor cavity 24, so its radiating effect is good not as preceding two embodiments.
