Problems solved by technology

Existing air pumps generally use AC series-excited motors to produce electric charging-suction dual-purpose air pumps and electric air pumps, etc., because the power supply control circuit design of the current AC series-excited motors is not optimized enough, and the required operating voltage is relatively large, so the operating temperature rises , large current, high power, large motor sparks, a great potential safety hazard; and loud, harsh noise

Embodiment

[0065] Embodiment: a built-in electric air pump capable of inflating and exhausting, such as Figure 1 to Figure 4 As shown, it includes a connection seat 1 for assembly on an inflatable product, a housing 2 built into the inflatable product, a pump body 3 provided on the housing, and a drive assembly 4 installed on the connection seat. The seat has a first air port 11, and the pump body has an air inlet and an air outlet 312;

[0066] The housing 2 has a second air port 21, and the opening and closing of the second air port 21 can be realized by driving the drive assembly 4 to move the pump body 3 up and down;

[0067] When inflating, drive the drive assembly 4 to drive the pump body 3 to move downwards and form a seal between the outside of the pump body and the casing. Under the action of the pump body, the outside air passes through the first air port 11, the pump body The inner chamber, the air inlet, the air outlet 312 and the second air port enter the inflatable produc...

Abstract

The invention discloses a built-in electric air pump capable of being used for air inflation and exhausting. The built-in electric air pump capable of being used for air inflation and exhausting comprises a connecting seat, a shell, a pump body and a driving assembly. The connecting seat is provided with a first air opening, and the shell is provided with a second air opening. The driving assemblyis driven to drive the pump body to move up and down, and the second air opening can be opened and closed. The pump body comprises a shell body, an impeller structure and a motor, the shell body is provided with an air inlet and an air outlet, and a circuit board of the motor is provided with a power source control circuit, an AC-DC conversion circuit, a DC-DC conversion circuit , a rectificationfiltering output circuit, a voltage feedback circuit, a peak suppression circuit and a voltage output interface. According to the built-in electric air pump, by improving an exhaust structure, the impeller structure and the power source control circuit, convenient conversion of the air inflation state and the air exchange state of the built-in air pump is achieved, the air drawing and exhaustingefficiency of the air pump is improved, and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of air pumps, in particular to a built-in air pump for inflatable products. Background technique [0002] The air pump is a key component of various inflatable products (such as air mattresses, inflatable trampoline, inflatable sofas and large inflatable toys). It is installed on the inner side of the soft bladder of the inflatable products. Perform operations such as rapid inflation, pressure maintenance and rapid deflation to realize the functions of inflatable products that are inflated and unfolded for normal use, and deflated to reduce the volume of the space for storage. [0003] At present, the structures of the air pumps for inflatable products seen on the market mainly include a casing and a motor, an impeller, a solenoid valve, a sliding seat, and an air valve arranged in the casing. And, an air hole and an air groove are respectively arranged on the side surface and the bottom surface of the casi...
