Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6 show an embodiment of the micro air pump with single knob and double air chambers of the present invention. The air pump comprises a shell 1 and an air pump panel 2 covering the shell 1, wherein a space formed by the shell 1 and the panel 2 is divided into a first chamber 10 and a second chamber 20. The first chamber 10 and the second chamber 20 are separated by a partition plate 3, and the partition plate 3 between the first chamber 10 and the second chamber 20 is provided with air vents 31. A movable shutter 6 is provided in the first chamber 10, the movable shutter 6 cooperating with the main gear 51. The baffle 6 is fixed with a clamping column 61, and the main gear shifting fork 511 can shift the clamping column 61 to drive the baffle 6 to shift. A fan switch 7 is fixed behind the baffle 6, and the baffle 6 is shifted to trigger the fan switch 7 to start. The second chamber 20 has a first air chamber 201, a first piston 2011 and a first piston rod 2012 disposed in the first air chamber 201, a second air chamber 202, and a second piston 2021 and a second piston rod 2022 disposed in the second air chamber 202. The single-knob double-air-chamber micro air pump also comprises a switch mechanism, and the switch mechanism comprises a knob 4 and a transmission mechanism 5 which is matched and connected with the knob; the knob 4 is positioned on the air pump panel 2; the transmission mechanism 5 comprises a main gear 51 fixedly connected with the knob 4, a first slave gear 52 matched with the first piston rod 2012, and a second slave gear 53 matched with the second piston rod 2022; a shifting fork 511 is fixed on the main gear 51, a first curved wheel 521 is fixed on the first slave gear 52, and a second curved wheel 531 is fixed on the second slave gear 53; the main gear 51 is engaged with the first slave gear 42 and drives the first curved wheel 521 to rotate so as to drive the first piston rod 2012 to move up and down, and the main gear 51 is engaged with the second slave gear 53 and drives the second curved wheel 531 to rotate so as to drive the second piston rod 2022 to move up and down. In this embodiment, the main gear 51 is composed of a main upper wheel 512 and a main lower wheel 513 arranged in an up-down manner, the first slave gear 52 is engaged with the main upper wheel 512, and the second slave gear 53 is engaged with the main lower wheel 513. Thus, when the knob 4 is at the 0 degree state, the air vent 31 is blocked by the baffle 6, the first piston 2011 and the second piston 2021 close the first air chamber 201 and the second air chamber 202, and the blower is also at the pause state at the moment. When the knob 4 is rotated to an inflation gear, the knob 4 and the main gear 51 rotate to drive the first slave gear 52 and the second slave gear 53 which are matched with the main gear to rotate; the first cambered wheels 521 and the second cambered wheels 531 rotate, and the first piston rod 2012 and the second piston rod 2022 are pressed downwards to enable the first piston 2011 and the second piston 2021 to move downwards to open the inflation channel; simultaneously, the knob 4 is rotated to an inflation gear, at the moment, the knob 4 and the main gear 51 rotate, the main gear shifting fork 511 drives the baffle 6 to shift, the air holes 31 on the partition plate 3 are opened, meanwhile, the baffle 6 shifts to trigger the fan switch 7 to start, and at the moment, the wind generated by the fan enters the second cavity through the air holes and inflates through the first air chamber and the second air chamber. When the knob 4 is turned to the deflation position, the first piston 2011 passes through the elbow inflation tube and descends to the lowest position, and the inflation chamber becomes an deflation channel to perform deflation.

Most preferably, the main gear 51 is a half gear, and the shift fork 511 and the gear teeth of the main gear 51 are located on opposite sides of the main gear 51. As shown in fig. 6.
