Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, but it should not be construed that the scope of the above-described subject matter of the present invention is limited to the above-described embodiments.

As shown in fig. 1 to 10, a multifunctional air pump includes a manual inflating assembly and an electric inflating assembly,

a manual inflation assembly comprises a pump body 1 with an opening at the upper part, a middle pipe 3, an upper cover 9, a piston 4 and a handle 2, wherein the lower part of the handle 2 is connected with the upper part of the middle pipe 3, the upper part of the handle 2 is provided with a first air outlet 2-1 communicated with the middle pipe 3, the middle pipe 3 and the first air outlet 2-1 form an air outlet channel 3-1, the upper cover 9 is arranged at the upper part of the pump body 1 and is used for sealing the opening at the upper part of the pump body, the upper cover 9 and the pump body 1 are sealed to form an air chamber, the middle pipe 3 can be arranged on the upper cover 9 in a vertical sliding manner, the upper part of the handle 2 is provided with a pressure monitoring device 6 communicated with the first air outlet 2-1, the lower part of the middle pipe 3 is connected with the piston 4, the piston 4 can be arranged on the pump body 1 in a vertical sliding manner, the piston 4, the upper part of the piston 4 is provided with a first one-way diaphragm 8.

The electric inflation assembly comprises a shell 12 installed at the bottom of the pump body 1, a motor 10, a control panel 15 and a battery 13, the motor 10 and the battery 13 are installed inside the shell 12, the control panel 15 is installed outside the shell 12 and used for controlling the charging of the battery 13 and the opening and closing of the motor 10, the control panel 15 is connected with the pressure monitoring device 6, the lower portion of the motor 10 is provided with a blade 11, the lower portion of the shell 12 is provided with an air inlet cover 14, the upper portion of the shell 12 is provided with an air outlet cover 16, the air outlet cover 16 is provided with a second air outlet 16-1 communicated with a lower air chamber 1-2, the upper portion of the second air outlet 16-1 is provided with a second one-way diaphragm 17, the air inlet cover 14 is provided with a first air inlet. The first unidirectional membrane 8 and the second unidirectional membrane 17 are made of flexible material.

When the manual inflation assembly works, the air pressure of the lower air chamber 1-2 rises, the first one-way diaphragm 8 at the bottom of the piston 4 is lifted, and air flow enters the air outlet channel 3-1 through the one-way diaphragm 8 and is discharged through the air outlet 2-1 of the handle 2. At the moment, the one-way membrane 17 in the air outlet 16-1 of the electric inflation assembly is pressed tightly, and airflow cannot flow out from the end of the electric inflation assembly; when the electric inflating assembly works, air enters from the air inlet 1-3 of the pump body 1 and enters the air chamber through the air inlet 14-1 of the electric pump air inlet cover 14, the air in the air chamber is compressed due to the rotation of the blades 11, the pressure rises, the air flow enters the air outlet 16-1 of the air outlet cover 16 from the air guide hole 12-1 of the shell 12, at the moment, the second one-way diaphragm 17 in the air outlet 16-1 is lifted, and therefore the air flow can enter the air outlet channel 3-1.

The scheme that this use is novel to be provided can carry out the function according to different in service behavior and switch. When the air pressure of the inflatable object is lower, the electric inflating assembly can be applied to inflating. When the pressure monitoring device 6 in the handle 2 monitors that the air pressure reaches a preset pressure value, a signal is fed back to the control board 15 of the electric inflation assembly, and the electric pump is automatically closed.

When the object of aerifing needs the high pressure, can use electronic aeration component earlier to carry out the preinflation to the product, when atmospheric pressure reached preset atmospheric pressure value, electronic aeration component self-closing, manual aeration component of rethread carries out the high pressure to the product and inflates. Compared with a pure manual inflation assembly, the inflation frequency can be greatly reduced, and therefore the labor-saving effect is achieved.

When the air pipe is connected with the air inlet 1-3 of the pump body 1, the air can also be automatically pumped out to the inflatable product, so that the product can be stored to reach the minimum volume.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way, and other variations and modifications are possible without departing from the scope of the invention as set forth in the claims.
