Abstract
Description
Technical Field
[0001] The present application relates to the field of air pumps, and in particular to an electric air pump for both charging and discharging air. Background Art
[0002] An air pump is an inflating and suction device used for indoor storage bags, outdoor inflatable mattresses, and various inflatable products. To inflate inflatable products, a manual air pump is generally used, or an electric air pump is used for inflation. The inflation process is generally operated by connecting the air pump to the air nozzle of the inflatable product. To deflate inflatable products, the air nozzle of the inflatable product is generally opened to allow the inflatable product to deflate naturally. Existing electric air pumps often have low air flow and insufficient air pressure when inflating inflatable products, which affects the efficiency of the air pump. Utility Model Content
[0003] In order to improve the problem of small air flow and insufficient air pressure when the air pump is inflated, the present application provides an electric air pump for both charging and deflation.
[0004] The present application provides a dual-purpose electric air pump for charging and discharging air, which adopts the following technical solution:
[0005] An electric air pump for both charging and discharging air comprises a shell, a movement is arranged in the shell, two movement air intake ports are arranged on the movement longitudinally opposite to each other, an electric pump air intake port is arranged on the top of the shell, and air flows into the movement air intake port from the electric pump air intake port; a movement inflation port is arranged on the side wall of the movement, and an electric pump inflation port is arranged on the side wall of the shell, the movement inflation port is aligned with the electric pump inflation port, and the side wall of the movement inflation port is pressed against the side wall of the shell; a fan blade is arranged in the movement, and a motor for driving the fan blade to rotate is arranged in the shell.
[0006] In one embodiment, the fan blades include a partition and a plurality of fan blades, wherein the partition divides the fan blades longitudinally into two fan blade groups, and the two fan blade groups correspond one by one to two air intake ports of the movement respectively.
[0007] In one embodiment, a battery for supplying power to the motor is disposed in the housing.
[0008] The embodiment of the present disclosure provides an electric air pump for both charging and discharging, which can achieve the following technical effects:
[0009] When the air pump is working, the motor drives the fan blades to rotate, and the airflow enters the housing through the electric pump air intake port. At this time, part of the airflow enters the movement from the movement air intake port at the top of the movement, and part of the airflow enters the movement from the movement air intake port at the bottom of the movement. The two parts pass through the movement inflation port and are discharged from the electric pump inflation port, thereby doubling the airflow and air pressure of the air intake and inflation, and improving the use efficiency.

DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0017] The following is combined with Figure 1-3 This application is described in further detail.
[0018] An electric air pump for both charging and discharging air comprises a shell 1, a movement is arranged in the shell 1, two movement air intake ports 2 are arranged in the longitudinal direction of the movement opposite to each other, an electric pump air intake port 3 is arranged on the top of the shell 1, and air flows into the movement air intake port 2 from the electric pump air intake port 3; a movement inflation port 4 is arranged on the side wall of the movement, and an electric pump inflation port 5 is arranged on the side wall of the shell 1, the movement inflation port 4 is aligned with the electric pump inflation port 5, and the side wall of the movement inflation port 4 is pressed against the side wall of the shell 1, which helps to prevent air leakage; a fan blade 6 is arranged in the movement, and a motor 7 for driving the fan blade 6 to rotate is arranged in the shell 1.
[0019] When the air pump is working, the motor 7 drives the fan blade 6 to rotate, and the airflow enters the housing 1 through the electric pump air inlet 3. At this time, part of the airflow enters the movement from the movement air inlet 2 at the top of the movement, and part of the airflow enters the movement from the movement air inlet 2 at the bottom of the movement. The two parts pass through the movement inflation port 4 and are discharged from the electric pump inflation port 5, thereby doubling the airflow flow of air intake and inflation and doubling the air pressure by improving the movement structure, thereby improving the use efficiency.
[0020] In one embodiment, the fan blade 6 includes a partition 9 and a plurality of fan blades 8, and the partition 9 longitudinally divides the fan blade 8 into two fan blade 6 groups, and the two fan blade 6 groups correspond to the two core air inlets 2. Using the partition 9 to divide the fan blade 8 into two fan blade 6 groups helps to avoid mutual interference between the airflows entering the two core air inlets 2.
[0021] In one embodiment, a battery 10 for supplying power to the motor 7 is disposed in the housing. The air pump can be used at any time and can be taken outside by using the battery 10 for power supply.
