detailed description

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding technical features.

FIG. 1 is a schematic diagram of an outer surface of an inflator 110 of a vehicle-mounted tire inflating device according to an embodiment of the present invention. A rubber barrel of the vehicle-based tire inflating device (not shown, see the rubber material in FIG. 3). The bucket 230) is adapted to be joined to the outer surface 111. Features of the switch 112 and the display panel 113 on the surface are also shown in FIG. 1. FIG. 2 is a schematic view of a bucket cover 120 of a rubber bucket, which is adapted to be joined to the outside surface in FIG. 1.

For example, the inflator may include, but is not limited to, a motor, a compressor unit, and the like, which may be built into the housing of the inflator. The inflator can be used to inflate a car tire.

The rubber bucket of the vehicle-mounted tire inflating device of this embodiment may have a bucket cover 120 as shown in FIG. 2. The glue outlet 121 on the bucket cover 120 is also shown in FIG. 2.

In this embodiment, the inflator and the rubber bucket may be separated. In the standby state, they can be placed in different storage spaces of the vehicle, which is beneficial to portability on vehicles with different storage capabilities. For example, it can be placed on different doors, or in different positions such as the trunk, and the storage space in the car can be used reasonably. When the tire is in an abnormal state, the two can be assembled together in a detachable manner at any time according to the situation, so that the tire can be properly maintained. This split-type vehicle tire inflation device also avoids the use of three-way valves and other components in the inflator, which is helpful to simplify the structure and reduce manufacturing costs.

A first connection portion 114 on an outer surface of a housing of the inflator is shown in FIG. 1. In an alternative embodiment, different numbers of first connection portions may also be provided on more than one outer surface of the casing, which facilitates the inflator and the rubber barrel to have multiple joint positions and flexible cooperation methods. For example, in different matching modes, an inflator or a rubber bucket can be used as the base of a vehicle-mounted tire inflating device as required, or they can have appropriate relative positions, so that the entire device remains stable and reliable during the inflated tire. Especially when the inflator is designed to be smaller and lighter, you can use a rubber bucket as the base of the inflator, or use the inflator and the rubber bucket to provide support for the assembled vehicle tire repair device. For example, when a vehicle-mounted tire repair inflating device is placed on the ground, both the inflator and the rubber bucket provide a base at the same time, and each part contacts the ground to provide support.
