Problems solved by technology

The vacuum tire does not have a closed body. At the beginning of the air supply, it is necessary to quickly supply air to form an air seal between the tire and the wheel hub. However, due to the limited air pressure of the existing pump, it is difficult to release a large amount of air in a short period of time. , so it is extremely difficult to replenish air to vacuum tires, which is also one of the difficulties in the large-scale promotion of vacuum tires

Embodiment 1

[0042] Embodiment one, such as Figure 1 to Figure 7 as shown,

[0043] A pump with a self-pressurizing structure, including a base 1, an air outlet pipe 2 is connected to the base 1, an inner pipe 3 is connected to the base 1, and a piston check valve assembly 31 is arranged on the upper end of the inner pipe 3, An outer tube 4 is arranged outside the inner tube 3 , the upper end of the outer tube 4 is connected with a handle 41 , the lower end of the outer tube 4 is provided with an outer tube sliding sleeve 42 between the outer tube 4 and the inner tube 3 , and the base 1 is provided with a The horizontal air passage 1a connected with the outlet pipe 2 and the vertical hole 1b connected with the inner pipe 3, an adjustment mechanism is arranged between the horizontal air passage 1a and the vertical hole 1b, and the adjustment mechanism can close the horizontal air passage 1a or the vertical hole 1b. Hole 1b;

[0044] When inflating and high-pressure air outlet, the adjust...

Embodiment 2

[0058] Embodiment two, such as Figure 8 to Figure 10 as shown,

[0059] The pump in this embodiment is similar in structure to the pump in Embodiment 1, the difference is that in this embodiment, the adjustment mechanism is a rotary valve core 6 that rotates with the base 1, and the inner end surface of the rotary valve core 6 A central hole 6a is opened in the axial direction, and the central hole 6a communicates with the transverse air passage 1a, and the rotary valve core 6 is also provided with a radial hole 6b, and the radial hole 6b is opened to the central hole 6a;

[0060] When the rotary spool 6 is opened, the radial hole 6b is connected to the vertical hole 1b, and the vertical hole 1b is connected to the horizontal air passage 1a; when the rotary spool 6 is closed, the vertical hole 1b and the horizontal air passage 1a are staggered, and the vertical hole 1b is closed by the rotary spool 6 .

[0061] working principle:

[0062] When the rotary spool 6 is rotated...

Embodiment 3

[0063] Embodiment three, as Figure 11 to Figure 13 as shown,

[0064] The pump in this embodiment is similar in structure to the pump in Embodiment 1, the difference is that in this embodiment, the adjustment mechanism is a screw valve core 7 screwed to the base 1, and the screw valve core 7 The inner side of the inner side is provided with a reduced diameter section 71, and the outer side of the screw valve core 7 is fixed with a rotary handle 73 by a latch 72;

[0065] When the screw spool 7 was opened, the inner end surface of the screw spool 7 left the inlet of the horizontal air passage 1a, and the vertical hole 1b was connected to the horizontal air passage 1a; when the screw spool 7 was closed, the The inner end surface forms a seal with the inlet of the transverse air passage 1a, and the transverse air passage 1a is closed by the screw valve core 7.

[0066] Setting the rotary handle 73 facilitates the rotation of the screw valve core 7 .

Abstract

The invention discloses an inflator with a self-supercharging structure. The inflator comprises a base; the base is connected with an exhaust pipe; the base is connected with an inner pipe; a piston check valve module is arranged at the upper end of the inner pipe; an outer pipe is arranged out of the inner pipe; the upper end of the outer pipe is connected with a holding handle; an outer pipe slide sleeve is arranged at the lower end of the outer pipe between the outer pipe and the inner pipe; the base is provided with a transverse air way communicating with the exhaust pipe and a vertical hole communicating with the inner pipe; an adjusting mechanism is arranged between the transverse air way and the vertical hole, and can close the transverse air way or the vertical hole; in inflation or high-pressure exhausting, the adjusting mechanism is started to conduct the vertical hole with the transverse air way; and in air storage, the adjusting mechanism is stopped to cut off communicationbetween the vertical hole and the transverse air way. The inflator has the advantages of reasonable and compact structure and convenience to use; through control by the adjusting mechanism, self supercharging of gas in the inner pipe can be realized; and the inflator can meet inflation demands of general tires and vacuum tires.

Description

technical field [0001] The invention relates to the technical field of pump manufacturing, in particular to a pump with a self-pressurizing structure. Background technique [0002] Bicycle tires can be divided into hollow tires and solid tires. Although solid tires are easy to maintain (no need to replenish air), the riding experience is far inferior to hollow tires; hollow tires can be divided into ordinary tires with inner tubes and vacuum tires without inner tubes. Tires are more economical, so they are the most commonly used, but ordinary tires are heavy and troublesome to repair, while vacuum tires have the advantages of good wear resistance, puncture resistance, light weight, and convenient maintenance, and are more and more popular among consumers. favorite. [0003] Ordinary tires, the inner tube of which is a closed body, are relatively easy to inflate through the air nozzle (return valve), whether through an air pump or an ordinary household pump. The vacuum tire...
