Built-in gas storage pump

This creation is related to the pump, and more specifically to a built-in gas storage pump.

According to the prevailing trend of riding bicycles, the related components of bicycles have also developed rapidly. Therefore, there is a bicycle tire with or without inner tube type. This type of tubeless bicycle tire can effectively reduce rolling resistance and has more The convenience of installation has gradually become a favorite of users.
However, such a tubeless bicycle tire needs to be injected with a high pressure to inflate the gas when inflating. Therefore, in the past, the user was only able to inflate with a pneumatic pump. However, at present, the industry has developed a gas storage type air pump, which mainly adds a gas storage cylinder to the original air pump to allow the gas to be pre-stored in the gas cylinder to reach a high pressure storage state. It is released at high pressure and can inflate bicycle tires without tubeless.
However, such an inflator that adds an air reservoir externally not only increases the volume, but also causes inconvenience in carrying and storing, and the overall aesthetics is greatly reduced.

In view of this, in order to improve the prior art, the conventional inflating gas cylinder has an increase in the overall volume, resulting in inconvenience of carrying and storage, and poor aesthetics; thus, the creation provides a built-in gas storage. The pump includes: a base having an accommodating area and an inner cylinder fixing hole; and an inner cylinder being a hollow cylinder, wherein the bottom end of the inner cylinder is fixed to the inner cylinder of the pedestal The outer cylinder is a hollow cylinder, the bottom end of the outer cylinder is slidably connected to the inner cylinder, the top end of the outer cylinder is closed, and the outer cylinder can be subjected to an external force to perform an axis with respect to the inner cylinder. Reciprocatingly sliding; a non-return device is coupled to the inner cylinder such that gas can only enter the inner cylinder from the outer cylinder unidirectionally; a gas guiding seat having a gas guiding body and a choke valve, the main system of the air guide seat is connected to the accommodating area of the pedestal, and has a air flow channel and a damper chamber, and the air flow channel is connected with the inner tube, and the gas dam chamber is Connected to the air guiding channel, the choke valve is disposed in the choke chamber and can be subjected to an external force Switching between an open position and a closed position; a gas transmission joint is connected to the gas guide seat, and communicates with the gas barrier chamber to connect the gas output; a switching member is pivotally connected to The pedestal is coupled with the choke valve, and the switching member can be switched between an air supply position and a gas storage position by an external force; when the switching member is located at the gas storage position, the linkage is interlocked The choke valve is switched to the closed position to close the choke chamber, and the gas in the inner cylinder cannot be transported to the gas transmission joint. When the switching member is in the gas transmission position, the choke valve is interlocked Up to the open position, the choke chamber is opened, and the gas in the inner cylinder can be transported to the gas transmission joint via the air guiding duct and the choke chamber; thereby achieving aesthetics, reducing volume and facilitating carrying And the effect of storage.

The inside of the inner cylinder 20 is stored. Since the gas barrier valve 62 is in a closed state at this time, the gas in the inner cylinder 20 cannot be output to the gas transmission joint 80, and can be input into the air pressure chamber chamber 16 via the air flow passage 613. The pressure value of the gas is displayed by the air pressure gauge 90 for the user to know the pressure of the gas stored in the inner cylinder 20.
Then, when the object of the outside world is to be inflated by the present creation, the user switches the switching member 70 from the gas storage position to the gas delivery position (as shown in FIG. 5), and the gas barrier is interlocked by the switching member 70. The valve 62 is switched from the closed position to the open position, so that the gas transmission joint 80 and the air flow passage 613 are in an open state at this time, so that the gas stored in the inner cylinder 20 can pass through the air guide passage 613. The gas barrier chamber 614 enters the gas pipe 81 of the gas transmission joint 80, and is output from the gas nozzle joint 82 to the outside articles to achieve the effect of inflation.
Therefore, the creation can not only store gas in the inner cylinder in advance, but also the design of the gas storage does not need to add an external air reservoir, but can reduce the overall volume, so as to facilitate carrying and storage, and can enhance the overall aesthetic effect. .
