Inflating device with air storage barrel

Abstract

The invention relates to an inflating device with an air storage barrel. The inflating device with the air storage barrel is arranged on a carrier table, and the inflating device and the air storage barrel are in a parallel air supply configuration mode through a control valve; the control valve is coupled to a shaft rod, the shaft rod is externally connected with an force exerting unit and provided with a cam with a first area and a second area, and the control valve is provided with a main hole opposite to the cam, a air valve communicated with the air storage barrel, an air inlet passage for air feeding of the inflating device, and an air outlet passage for supplying air outwards; the main hole is slidingly matched with a slider, the slider elastically abuts against the cam, and a valve is elastically hung on the slider; the force exerting unit can drive the cam to be positioned at a first angle and a second angle, when the cam is at the first angle, the first area drives the slider to a first position to communicate the air inlet passage and the air outlet passage, the valve closes the air valve, and further the inflating device can be in an air outlet passage air supply mode; when the cam is at the second angle, the second area drives the slider to a second position, the slider closes the air outlet passage, the valve opens the air valve, so that the air valve can be communicated with the air inlet passage, and further the inflating device can be in a storage barrel air supply mode.

Description

technical field [0001] The invention provides a technique for integrating an inflating device and an air storage tank, and specifically refers to an inflating device with an air storage tank. Background technique [0002] The prior art is just as shown in the U.S. No. 6,883,565 patent, such as its image 3 As shown, it mainly rotates 360 degrees through the valve body to switch the three operation modes of external air supply from the inflator, external air supply from the air storage tank, or external air supply from the inflator to the air storage tank. These three operating modes exist independently Therefore, in addition to controlling the force and position of the rotating valve body by hand, the user must also visually observe the valve body to reach the desired fixed point position. It can be seen that it can only be completed through hand-eye coordination, and the rank is at least There are three, so the overall operation is very troublesome, and the hand is often in...

[0002] The prior art is just as shown in the U.S. No. 6,883,565 patent, such as its image 3 As shown, it mainly rotates 360 degrees through the valve body to switch the three operation modes of external air supply from the inflator, external air supply from the air storage tank, or external air supply from the inflator to the air storage tank. These three operating modes exist independently Therefore, in addition to controlling the force and position of the rotating valve body by hand, the user must also visually observe the valve body to reach the desired fixed point position. It can be seen that it can only be completed through hand-eye coordination, and the rank is at least There are three, so the overall operation is very troublesome, and the hand is often inaccurate in controlling the rotation position of the valve body, and it is very difficult to control the force. It is necessary to adjust the position repeatedly, wasting a lot of time, especially in an emergency, which is even more annoying. It is really a big failure in the use of the structure, causing users to be unable to switch as they wish. Many related manufacturers have spared no effort in research and development, but so far there is still no better structure to overcome the above-mentioned shortcomings.
