Problems solved by technology
[0003] The above-mentioned traditional air pump uses the hand wheel on the shell to switch the valve plate in and out of the air hole, which has the following disadvantages: (1) The structure is complex: there are many parts of the transmission mechanism matching the hand wheel and it takes up a lot of space, and the production and assembly are complicated
(2) The sealing effect is not good: the handwheel and the internal inflation and deflation space are prone to air leakage due to the repeated rotation and unscrewing of the handwheel

Embodiment Construction
[0069] Please refer to Figure 1 to Figure 15 As shown, it shows the specific structure of the preferred embodiment of the present invention. The air pump is used to inflate / deflate products such as air mattresses, inflatable jump beds, inflatable sofas, and inflatable toys. The air pump includes a housing 10, a blower device 20 installed in the housing 10, a flow direction switching device 30, a pressing button device 40 installed on the top panel of the housing 10, and a storage line for accommodating the power cord of the air pump. device 70.
[0070] Among them, such as Figure 1-3 As shown, the housing 10 is composed of an upper housing 101, a middle housing 102 and a lower housing 103, and the upper, middle and lower housings 101, 102, 103 are detachably connected. The top of the housing 10 is a horizontal panel, on the top panel, a first air charging port 11 and a first air discharge port 12 are provided, and a direction switching device 30 is arranged in the housing ...

The invention discloses a push-button type air pump, which comprises a casing, a blower device and a push-button device. The top panel of the casing is provided with a first inflation port and a first discharge port. The push-button device includes an openable or The depressing inflation button that closes the first inflation port, the depressing deflation button that can open or close the first deflation port, and the lower part of the shell is provided with a second inflation port and a second deflation port, the second inflation port and the second There is a direction switching device between the deflation ports to separate the inflation air channel and the deflation channel; when the inflation button is pressed, the inflation air channel is opened and the blowing device is activated; when the deflation button is pressed, the flow direction switching device is activated Close the inflation air duct and open the deflation channel; by pressing the inflation button and the deflation button to control the inflation and deflation, the complex structure of the traditional rotary control is simplified, and the overall volume of the product is reduced. Simple and easy to operate.
