Description

Air pumping device with gas storage bucket

The invention provides a technology for integrating a gas pumping device and a gas storage tank. More specifically, it can be conveniently supplied to the gas pumping device externally, the air supply tank externally supplying air, and the air pumping device only by pressing or pulling up. The three operation modes of the air supply of the gas storage bucket are switched, wherein the air supply device or the external gas supply system of the gas storage bucket belongs to the same parallel section, so that the user can perform the desired operation.

According to the prior art, as shown in the third patent of the U.S. Patent No. 6,883,565, as shown in the third figure, it is mainly rotated 360 degrees through the valve body to switch the external air supply of the air pump, the air supply to the air tank, or The air pumping device supplies three operating modes to the gas storage tank. The three operating modes exist separately, so the user must visually control the rotating valve body force and position by hand, and visually observe the valve body to reach the desired fixed position. It can be known that it must be coordinated through hand-eye coordination, and there are at least three segments, so the overall operation is troublesome, and the hand is often inaccurate in controlling the rotational position of the valve body. It is difficult to control the force and must be repeatedly repeated. Adjusting the position, wasting a lot of time, especially in an emergency, it is even more annoying. It is a big failure in the use of the structure, which makes the user unable to switch with ease. After many related manufacturers spare no effort to carry out research and development, but still There is no better structure to overcome the aforementioned shortcomings.

In view of this, and invented by the multi-party test design, the present inventors have succeeded in developing a more progressive invention to completely solve the problems of the conventional structure.

The present invention provides a gas pumping device having a gas storage tank, comprising: a loading platform provided with an approach channel, and a one-way valve is installed at one end of the approach channel; and an air pumping device having a cylinder fixed to the carrier The cylinder is slidably equipped with a piston, which can be acted upon by the linkage rod to ignite the gas, forcing the gas to pressurize and enter the approach channel through the one-way valve; a gas storage barrel fixed to the stage; The control valve of the gas barrel is provided with a pivot hole, a main hole intersecting the pivot hole, a valve connecting the main hole and the gas storage barrel, an inlet port connecting the main hole and the other end of the approach channel, and a communication The main hole can be externally supplied with air; the pivot hole is coupled with a shaft, the shaft is externally provided with a force applying portion, and a cam is provided at the main hole position, the cam has first and second regions; the main hole is slid The slider has an intermediate hole, the slider is driven by the first spring to abut one end of the cam, and the other end of the slider is elastically suspended with a shutter; the force applying portion can drive the cam at the first and second angles Positioning, at the first angle, the first zone acts on the slider to the first position, at which time the intermediate hole is connected to the intake air The air outlet is closed, and the valve is closed to the air supply mode of the air outlet according to the air pumping device. However, when the air pressure of the air tank is sufficient to push the valve to open the valve, the air tank can supply air to the air outlet; When the cam is positioned at the second angle, the second zone acts on the slider to the second position, at which time the slider closes the air passage, and the shutter opens the valve and connects the intermediate hole and the intake port to respond to the air. The device supplies air to the gas storage tank.

By summarizing the above description, it is known that the present invention can be switched between the three modes of operation of the external air supply of the air pump, the external air supply of the air tank, and the air supply of the air pump to the air tank by only pressing or pulling up the force applying portion. In particular, the air pumping device and the gas storage tank are in parallel air supply configuration. Therefore, when the air supply barrel is insufficiently supplied with the gas to be inflated (for example, the tire), the present invention does not need to perform any switching, and the air pumping device is directly operated. Connect Continuing to supply the gas to be inflated to the target pressure value, it is known that the overall operation of the present invention is quite clear and simple, and it is indeed possible to complete the action of supplying gas to the inflated body at the fastest time, and is a significant effect. Increase the height of creation.
