Detailed Description

The following description of the embodiments of the present utility model will be apparent from, and is intended to provide a thorough description of, the embodiments of the present utility model, and not a complete description of, the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.

Example 1

Referring to fig. 1-7, a novel water mortar comprising:

a launch canister 100; in the actual use process, supporting feet 101 can be arranged on two sides of the transmitting cylinder 100; referring to fig. 1 and 2, two sides of a transmitting cylinder 100 are symmetrically fixed with a hinge post 102, a supporting leg 101 is hinged on the hinge post 102, an outer end of the hinge post 102 is in threaded connection with a fastening cap 103, and when the fastening cap 103 is screwed, an inner end of the fastening cap 103 is abutted against the supporting leg 101;

the base 200 is in threaded connection with the lower end of the launching tube 100, a firing pin 201 which is vertically upwards is fixed on the base 200, and the central axis of the firing pin 201 is coincident with the central axis of the launching tube 100;

a mortar body 300 corresponding to the firing barrel 100, the mortar body 300 being a bottle;

a sealing seat 400 screwed to the opening of the lower end of the mortar body 300, wherein a thin sheet 401 is arranged at the lower end of the sealing seat 400; a check valve 402 is fixed to one side of the sealing seat 400; a horn-shaped limiting cylinder 403 is connected to the center of the lower end of the sealing seat 400; the tab 401 is located at the bottom of the seal holder 400 and seals against the top of the stopper rod 403.

In this embodiment, a fixed cylinder 404 is further disposed in the seal seat 400; the fixed cylinder 404 abuts on the top of the sheet 401; the side wall of the fixed cylinder 404 is provided with a yielding groove 4041 corresponding to the one-way valve 402, and the yielding groove 4041 extends from the bottom of the fixed cylinder 404 to the middle; when the sealing socket 400 is screwed on, the lower port of the mortar body 300 abuts against the top of the fixing cylinder 404 and thereby fixes and seals the sheet 401 on the top of the stopper cylinder 403.

In use, after a certain amount of water is injected into the mortar body 300, the sealing seat 400 is connected, when the sealing seat 400 is screwed, the lower port of the mortar body 300 is abutted against the top of the fixing cylinder 404, and the bottom of the fixing cylinder 404 is abutted against the sheet 401, so that when the sealing seat 400 is screwed, the sheet 401 is fixed and sealed on the top of the limiting cylinder 403. Air is then fed into the mortar body 300 through the non-return valve 402 by means of an external tool, thereby increasing the internal pressure in the mortar body 300, and is stopped when the proper air is injected into the mortar body 300.

The firing barrel 100 is supported on the ground and then the mortar body 300 is put into the firing barrel 100 from the top of the firing barrel 100. The mortar body 300 slides obliquely downward along the firing barrel 100, and when sliding to the bottom, the firing pins on the base 200 pierce the thin sheet 401, and water and air are released from the inside of the mortar body 300 to push the mortar body 300 to be fired.
