Embodiment

Consult shown in Fig. 2,3,5, be a preferred embodiment of the present utility model.A kind of air pump comprises pump case 3, power plant, two groups of transmission devices that are connected with power plant and two diaphragms 6 that are connected with two groups of transmission devices respectively.

Described pump case 3 fixedly is made of from top to bottom successively top cover 31, first valve seat 32, main body 33, second valve seat 34 and base 35; Be respectively equipped with suction port 36 and air outlet 37 on top cover 31 and the base 35; Be respectively equipped with suction valve 38 and gas outlet valve 39 on first valve seat 32 and second valve seat 34, breather cheek valve 38 connects suction port 36, and unidirectional gas outlet valve 39 connects air outlet 37, Sealing can be set to increase its tightness (not shown) between one-way valve and the valve seat.

Adopt motor 4 as power plant in the present embodiment, motor 4 is arranged at main body 33 outsides, cooperates transmission device that the circular movement of motor output shaft 41 is converted into straight reciprocating motion.In addition, also can adopt magnetic coil to produce alternating magnetic field, drive the rocking arm that is provided with permanent magnet and do straight reciprocating motion (this kind driving mode is a known technology, repeats no more in the literary composition).

Described transmission device is arranged in the main body 33, comprise an eccentric wheel 51, with eccentric wheel 51 close-fitting bearings 52 and be drive wheel 53 cylindraceous; Eccentric wheel 51 is arranged on the output shaft 41 of motor 4; Bearing 52 is positioned at drive wheel 53 inboards.Utilize eccentric wheel 51 that the circular movement of motor output shaft 41 is converted into straight reciprocating motion.

6 one of two diaphragms are located between first valve seat 32 and the main body 33, and another is located between second valve seat 34 and the main body 33.Referring to Fig. 4, shown in Figure 6, described diaphragm 6 is made by rubber material, be similar bowl-type, curved surface place is thinner around it, the midplane place is thicker, and plane place respectively covers the reinforced layer 61 that one deck hard material (as tinsels such as iron, copper, or plastic sheet) is made up and down, to increase its structural strength, prolong the working life of diaphragm.Compare with the uniform bowl-type diaphragm of existing thickness, the curved surface place in produce deformation and can avoid curved surface place and reinforced layer 61 frictions on every side as far as possible, prolongs the working life of diaphragm than small profits around the diaphragm 6 that the utility model provides.Diaphragm 6 centers are provided with the through hole 62 that is pivoted for screw, are pivoted by screw and are fixed on the drive wheel 53.Diaphragm 6 edges turn up, and are fixed on the main body 33, surround an air cavity 7 that seals with valve seat.

Like this, motor 4 output shafts 41 drive two eccentric wheels 51, drive two groups of transmission devices simultaneously, drive two diaphragms 6 respectively and do straight reciprocating motion, worked simultaneously in two groups of suction ports 36 and air outlet 37, the user can carry out many group inflations, the operation of bleeding simultaneously by selecting distinct interface.

As shown in Figure 7, top cover 31, first valve seat 32 are hubbed on the main body 33 by screw, and its one is rotated with respect to main body 33, adjust suction port 36 and air outlet 37 and screw are locked to the required direction again and got final product.Same, but the base 35 and second valve seat 34 also one rotate with respect to main body 33, make suction port 36 and air outlet 37 towards different direction, to adapt to different application needs, use convenient flexible.

Except that the embodiment who is provided with two groups of transmission devices, two diaphragms 6 and two groups of suction ports 36 and air outlet 37 of the above, the utility model more can make full use of the space of the kinetic energy and the pump housing of power plant, many group transmission devices are set in pump main body 33, the circular movement of motor 4 output shafts 41 is converted into straight reciprocating motion on the different direction, drive the size that a plurality of diaphragms 6 change each air cavity 7 respectively, thereby worked simultaneously in many group suction ports 36 and air outlet 37.

In addition, the utility model is except that can adopting diaphragm 6, also can adopt the diaphragm of other form, diaphragm 1 as shown in fig. 1, the convex configuration of its upper end is beneficial to the air in the air cavity 7 is drained, thereby when bleeding, can reach bigger degree of vacuum, and diaphragm of the present utility model 6 has bigger gettering quantity, therefore can adopt different diaphragms according to different user demands.
