Embodiment 1

[0025] Such as figure 1 , 2 As shown, the present invention discloses a dual-purpose inflatable gun, including a gun body 900, a trigger 200 as an airway switch, and a movable valve device 300; The gun handle at the end; the main air passage 400 is arranged inside the gun body; it is characterized in that: the dual-purpose inflatable gun also includes a vacuum device 600 and a switch device 700 of the vacuum device, and the vacuum device The device 600 is located in the main airway 400; the vacuum pumping device 600 includes a main airflow inlet 602, a secondary airflow inlet 603, and an airflow outlet 605; the main airflow inlet 602 and the secondary airflow inlet 603 communicate with the main airway 400, and the airflow The outlet 605 is connected to or isolated from the external atmosphere through the switch device 700 of the vacuum pumping device.

[0026] The main air passage 400 includes an air intake passage 401 located in the gun handle, a switch air passage 402 for ...

Embodiment 2

[0039] Such as Figure 5 , 6 As shown, the difference between the dual-purpose air gun disclosed in this embodiment and the first embodiment is that the dual-purpose air gun is also provided with a silencer 702, and the silencer 702 is located at one end of the sliding cavity 607, and It is airtightly connected with the sliding chamber 607.

[0040] Due to the use of the muffler 702, it is possible to avoid sharp air flow sounds when the gas flows into the outside air.

Embodiment 3

[0042] Such as Figure 7 , 8 As shown, the difference between the dual-purpose air gun disclosed in this embodiment and the first embodiment is that the dual-purpose air gun also includes an instrument air passage 901; The main airway is connected, and the connecting airway 403 and the instrument airway 901 are not the same forming hole; the bottom end of the air outlet part 604 of the vacuum device 600 is located in the connecting airway 403, and its main body passes through the connecting airway 403 and extend out of the gun body 900, the instrument 800 is airtightly installed on the top of the instrument air passage 901; the top of the vacuum device 600 is provided with a switch cap 710, and the air outlet 605 of the vacuum device 600 passes through the switch cap The cap 710 is open or isolated from the outside atmosphere.

Abstract

The invention provides a dual-purpose charge gun which has simple and compact structure, can be used as a charge device of an automobile tire, and can be used as a vacuumizing device of the automobile tire. The dual-purpose charge gun comprises a gun body, a trigger as an air flue switch and a moving valve device; the gun body comprises a gun tube as a charge tube and a gun handle as an air inflow tip; the inner part of the gun body is provided with a principal air flue; the principal air flue comprises an air inflow flue positioned in the gun handle, a switch air flue used for installing the moving valve device, a charge flue positioned in the gun tube and a connected air flue communicating the switch air flue and the charge flue. The dual-purpose charge gun also comprises a vacuumizing device and a switch device of the vacuumizing device, and the vacuumizing device is positioned in the connected air flue; the vacuumizing device comprises a principal airflow inlet, a secondary airflow inlet and an airflow outlet; and the principal airflow inlet is communicated with the switch air flue, the subordinate airflow inlet is communicated with the charge flue, and the airflow outlet is communicated with or isolated with the outer atmosphere through the switch device of the vacuumizing device.

Description

Technical field [0001] The invention belongs to a tire inflation and vacuum pumping device, in particular to an improved dual-purpose inflation gun. Background technique [0002] The automobile tire inflation gun of prior art one, as the announcement number is: the Chinese patent of CN2885668, comprises gun body, as the trigger of airway switch and the gun barrel as gas-filling pipe and the inflation nozzle of gas-filling pipe end, inside the gun body There is a main airway, and there is a side bronchus in the front part of the main airway, and a set of air pressure value sensing and display device is connected to the side bronchus; there is a side bronchus in the middle of the main airway. A deflation valve is installed on the side of the airway; the inflation switch device is arranged at the rear section of the main airway. Since the car tire inflation gun has a set of air pressure value sensing display device and a deflation valve on the airway, when the car tire is infl...
