Pump capable of pumping tubeless tire

Abstract

The invention provides a pump capable of pumping a tubeless tire. The pump comprises a pumping set, an airflow channel, an inflating set and a switching device, wherein the pumping set comprises an outer cylinder body, an air storage cylinder, a piston and a one-way valve, the piston is slidably arranged in the outer cylinder body, the one-way valve is arranged in the outer cylinder body, an air chamber is formed among the outer cylinder body, the piston and the one-way valve, the airflow channel comprises an air storage section and an inflating section, the air storage section is arranged inthe air storage cylinder, the inflating section can communicate with the air storage section, the air chamber communicates with the airflow channel in a one-way mode through the one-way valve, the inflating set is connected with the pumping set and comprises an inflating nozzle, the inflating nozzle can be connected with a to-be-inflated object, the switching device comprises an airflow valve setand a switch piece, the inflating section is arranged between the inflating nozzle and the switching device, the airflow valve set is contained in the airflow channel and comprises a jacking core, theswitch piece comprises an abutting and jacking part, and the abutting and jacking part selectively abuts and jacks the jacking core so that the air storage section can communicate with the inflatingsection and communicate with the to-be-inflated object through the inflating nozzle.

Description

technical field [0001] The invention relates to an air pump, in particular to an air pump capable of inflating a tubeless tire. Background technique [0002] With reference to the air pump for bicycles in Chinese Patent No. 100357593C, the air storage bottle is composed of a tank portion capable of storing compressed air and a connection port. Opens when attached to toggle, closes when air storage bottle is removed. The manual pump injects compressed air into the air storage bottle and consists of a cylinder, a piston inserted into the cylinder, a piston rod connected to the upper surface of the piston, and a grip part connected to the other end of the piston rod. The piston rod is inserted into and passed through the back of the cylinder. end ring plug. In addition, an air supply port for discharging air from the cylinder is formed at the front end of the cylinder. The switching valve consists of a first air port connected to the connection port of the air storage bottle...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the compressed air contained in the air storage bottle of the existing air pump cannot inflate the tubeless tire to the tire pressure required by the user, so it is necessary to turn the switching valve again to inflate the second air The port is connected to the air outlet, and the manual pump is inflated into the tubeless tire, so that when the user uses the air pump to inflate the tubeless tire, it is necessary to frequently operate the switching valve between the first air port, the second air port and the air outlet It is not convenient to change, the volume of the air storage bottle is larger than the maximum volume of one round trip of the manual pump, so that the user needs to spend a lot of time reciprocating the manual pump to bring the gas in the air storage bottle to the required pressure
