Description

A built-in double-airway inflation and extraction device

technical field

The invention relates to the field of air pumps, in particular to a built-in double-airway air charging and pumping device.

Background technique

Inflatable products such as inflatable tents, inflatable kayaks, inflatable cushions, and inflatable water toys are usually inflated with an external or hand-held air pump, and the inflation port of the air pump is aligned with the corresponding air nozzle to inflate. This method is cumbersome to hold and align the air nozzle, and it is not convenient to carry an external air pump.

Due to structural limitations, existing built-in air pumps usually only use a single motor. This type of built-in air pump can only inflate the air cavity but cannot pump air. Some air pumps that can be charged and pumped need to be switched between inflating and pumping The airway, which will lead to poor air leakage and poor airtightness of the airway, and the air extraction efficiency will be relatively low when switching the airway. Vacuum clean. For example, the Chinese utility model patent with the notification number CN210799428U discloses a "built-in electric air pump capable of inflating and exhausting". It has the function of pumping air. When it is exhausted, open the air port of the air pump to discharge part of the air under the inflation pressure, and then the remaining air needs to be exhausted by manually squeezing the air cavity, which is time-consuming, laborious and inefficient.

At present, the inflation method of inflatable products is relatively simple. Usually, the air pump can be used to inflate the air cavity, but it is more difficult to exhaust. The method of opening the air nozzle to deflate the air needs to frequently squeeze the air cavity to discharge the air, which cannot be exhausted and exhausted. Gas efficiency is low. The existing built-in air pump does not have an independent exhaust motor when exhausting. It is exhausted through its own air pressure in the air cavity. When the air pressure in the air cavity is balanced with the external air pressure, it will no longer be automatically exhausted. The remaining large amount of air in the air cavity needs to be manually operated frequently. Squeeze the air chamber to discharge, so the gas in the air chamber cannot be discharged quickly. It will be more difficult to exhaust the air chamber with a large volume of air. Manually squeezing the air chamber takes a long time to exhaust and the exhaust efficiency is low.

technical problem

In order to solve the problems of low air inflation and pumping efficiency and poor air leakage and sealing of the existing built-in air pump.
