Automatic stop controller and air pump using same

Abstract

The invention discloses an automatic stop controller and an air pump using the automatic stop controller. The air pump comprises a housing, a blower device, a microswitch and an automatic stop controller. The automatic stop controller comprises an outer housing, a moving part, a gear part, a swinging part, a moving ejector rob, a deformable air pressure sensing thin film and a knob, wherein the air pressure sensing thin film deforms to enable the moving ejector rob to move by using the change of the air pressure, the swinging part is enabled to swing due to the movement of the moving ejector rob, the gear part is enabled to rotate due to the swinging of the swinging part, the moving part is enabled to move due to the rotation of the gear part, and the microswitch is triggered due to the movement of the moving part, so that the aim of automatic stop can be realized. The invention further has the inventive step and the use convenience, the product has the characteristics of being intelligent and humanized, and reasonable in structural configuration, the structure of the product can be preferably simplified, each parts in the product is convenient to manufacture and assemble, and the effects of production efficiency improving and production cost reducing can be achieved.

Description

technical field [0001] The invention relates to the technology in the field of air pumps, in particular to an automatic shutdown control device and an air pump using the device. Background technique [0002] The air pump is a key component of various inflatable products (such as inflatable mattresses, inflatable jumping beds, inflatable sofas, inflatable toys, etc.), which are installed on the inner side of the soft capsule of the inflatable products, and the inflatable products can be operated by using the air pump. Quickly inflate, maintain pressure and quickly deflate, etc., to realize the functions of inflatable products, such as inflation and expansion for normal use, and deflation to reduce the space volume and facilitate storage. However, although the air pump products currently on the market have the aforementioned basic functions of inflation, deflation and pressure maintenance, some air pumps also have the function of automatic shutdown. , micro switch, movable ej...

Problems solved by technology

[0003] Although the above-mentioned existing automatic stop control device can realize the effect of automatic stop and bring great convenience to users, it is found that there are still serious deficiencies in its performance during actual use, and the best use effect cannot be achieved. and working efficiency, the main disadvantages are: because the micro switch and the main switch are set separately, when starting the air pump, it is necessary to close the main switch, and also need to slide the movable ejector to reset the induction film and close the micro switch. That is to say, two separate operations are required. If any switch is missing, the air pump will not work. Not only is the operation extremely cumbersome, but some new users who are not skilled in using it will easily forget to turn on the second switch and mistakenly think that the machine is broken. Inconvenience and distress for people to use and operate
