Embodiment Construction

[0021] According to attached figure 1 It can be seen that the present invention specifically relates to a portable air pump, which includes a gas tube 3 connected at both ends, one end of the gas tube 3 is connected with an air clip 4, and the other end is connected with an inflator, and the inflator includes a shell and an air tube located in the shell. The eccentric wheel 2-8, the eccentric wheel 2-8 is sleeved with a drawer that slides with it, and the drawer divides the inside of the shell into two independent cavities, which are respectively an air intake cavity and an exhaust cavity. The air intake chamber and the exhaust chamber respectively have passages communicating with the outside world, and a rotating rod 1 for driving the eccentric shaft 2-8 to rotate is arranged outside the housing.

[0022] According to attached figure 2 And attached image 3 As shown, the drawer is a double-layer annular structure with a horizontal bar on the outside, the inner layer is the...

Abstract

The invention discloses a portable inflator, belonging to the field of daily necessities. The portable inflator comprises an inflating pipe two ends of which are communicated, wherein one end of the inflating pipe is connected with a gas clamp and the other end of the inflating pipe is connected with an inflating device. The inflating device comprises a housing and an eccentric sheave located inside the housing, wherein the eccentric sheave is sleeved with a pumping member which is in sliding fit with the eccentric sheave, the pumping member divides the inside of the housing into two separate cavities: an air inlet cavity and an air discharging cavity both of which have channels communicated with the outside, and the outside of the housing is provided with a rotary rod driving the eccentric shaft to rotate. The portable inflator changes working principles of traditional inflators, and employs an eccentric sheave structure to compress the gas inside the housing so that the gas in the inner cavity can flow in and flow out at the same time. The rotary movement can effectively utilize space so that the inflator is enabled to have a compact form and volume of the inflator is reduced. Moreover, inflation can be completed only by a hand operation way, thereby saving time and effort.

Description

technical field [0001] The invention relates to an inflator, which belongs to the field of daily necessities, in particular to a portable inflator. Background technique [0002] As we all know, bicycles are the most convenient means of transportation for human beings. They can reduce the labor intensity of people. At the same time, they are also the best tool for the majority of bicycle enthusiasts to exercise. However, bicycles sometimes bring inconvenience to people. In the process of driving, the tire suddenly becomes flat or you forget to add air to the tire when you go out. This happens all the time, especially when you're traveling. In order to solve the above problems, you need a small and easy-to-carry inflator. At present, all the inflators on the market for refilling bicycles are cylindrical inflators. For those relatively large pumps, it is more convenient to refill, but it is not very convenient to carry, and for those relatively small mini pumps, although it i...
