Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1-4, the embodiment provides a pre-pressing gun, which includes a gun casing 1, the gun casing 1 is clamped in a housing, the housing includes an upper casing 101 and a lower casing 102 which are clamped with each other, the gun casing 1 includes a liquid outlet pipe 11, one side of the liquid outlet pipe 11 is communicated with a liquid storage tank 12 which extrudes internal liquid under pressure, the side wall of the liquid storage tank 12 is communicated with a pre-pressing groove 13 which is used for increasing the pressure of the liquid storage tank 12, the liquid storage tank 12 and the pre-pressing groove 13 are both communicated with an inner cavity of a connecting ring 14 which extends into a bottle body, and a pre-pressing part 2 which is used for increasing the pressure of the liquid storage tank; when the liquid storage tank works, the liquid in the liquid storage tank 12 is sprayed out through the liquid outlet pipe 11 by increasing the pressure in the liquid storage tank 12 through the matching of the prepressing piece 2 and the prepressing groove 13.

The prepressing piece 2 comprises a prepressing piston 21 which is arranged in the prepressing groove 13 and is attached to the inner wall of the prepressing groove 13, the side wall of the liquid outlet pipe 11 is rotatably connected with a trigger 22 for pushing the prepressing piston 21 to move, the outer end of the prepressing piston 21 is provided with a connecting ball 23 which is matched with a connecting hole of the trigger 22, an elastic component 24 for resetting the trigger 22 is also arranged between the trigger 22 and the connecting ring 14, and the elastic component 24 comprises a spring and a U-shaped elastic sheet; during operation, the trigger 22 is pulled inwards to drive the pre-pressing piston 21 to move inwards, the pre-pressing groove 13 is communicated with the liquid storage groove 12, therefore, the space of the pre-pressing groove 13 is reduced due to the inward movement of the pre-pressing piston 21, the pressure in the liquid storage groove 12 is increased, and the liquid in the liquid storage groove 12 can be discharged from the liquid outlet pipe 11 under the action of large pressure in the liquid storage groove 12.

A control valve core 3 for controlling the liquid outlet or closing of the liquid storage tank 12 is arranged in the liquid storage tank 12, a valve core seat 4 for placing the control valve core 3 is also arranged in the liquid storage tank 12, and an end cover 5 which is matched with the valve core seat 4 to limit and fix the control valve core 3 is also arranged at the upper end of the liquid storage tank 12; during operation, control valve core 3 is used for controlling the play liquid or the feed liquor in reservoir 12, and the cooperation of end cover 5 and valve core case 4 is used for carrying out spacing fixed to control valve core 3, avoids the change of reservoir 12 internal pressure to drive control valve core 3 and removes.

The side wall of the control valve core 3 is provided with two layers of piston rings 31, and the piston rings 31 are obliquely and upwards arranged and are attached to the inner wall of the liquid storage tank 12; during operation, the two-layer piston ring 31 that the slope set up has made things convenient for the assembly of whole pre-compaction rifle, and when the assembly promptly, control valve core 3 assembles into reservoir 12 through the mode that moves from the top down in, and the slope setting of 3 two-layer piston ring 31 of control valve core has made things convenient for control valve core 3 to assemble into reservoir 12 in.

The communication hole between the pre-pressing tank 13 and the liquid storage tank 12 is positioned between the two piston rings 31; when the liquid conveying device works, when the pressing trigger 22 drives the pre-pressing piston 21 to move, the pre-pressing piston 21 pushes liquid in the pre-pressing groove 13 into the liquid storage tank 12, at the moment, the piston ring 31 at the upper end of the control valve core 3 in the liquid storage tank 12 is pressed to shrink upwards to form a conveying channel, so that the liquid in the liquid storage tank 12 enters the liquid outlet pipe 11 through the channel, and the piston ring 31 at the lower end of the control valve core 3 is pressed to enable the liquid to be attached to the inner wall of the liquid storage tank 12 more tightly, so that the liquid in the liquid storage tank 12 can be conveyed into the liquid outlet pipe 11 from the.

Further, after once pressing, the trigger 22 is driven to reset under the action of the elastic part 24, the prepressing piston 21 is driven to move outwards in the resetting process of the trigger 22, negative pressure is formed between the upper piston ring 31 and the lower piston ring 31 of the control valve core 3 at the moment, the piston ring 31 at the upper end is influenced by negative pressure suction force to enable the piston ring to be attached to the liquid storage tank 12 more tightly, the piston ring 31 at the lower end is influenced by negative pressure to be separated from the side wall of the liquid storage tank 12 to form a channel, and liquid at the lower end is sucked into the liquid storage tank 12, so that liquid is supplemented into the liquid storage tank 12 for next pressing to.

Referring to fig. 4, it should be added that, no matter the control valve core 3 with two layers of piston rings 31 guarantees the stability of pressure during liquid discharging or the stability of liquid inlet amount during liquid inlet, it can realize quick conversion according to the prepressing piece 2, and when not in use, the two layers of piston rings 31 also guarantee the stability of liquid storage amount in the liquid storage tank 12, thereby guaranteeing the stability of liquid outlet amount during pressing use.

A liquid outlet valve core 6 for controlling the liquid outlet pipe 11 to be opened or closed is arranged at the liquid outlet end of the liquid outlet pipe 11, the liquid outlet valve core 6 is arranged in the liquid outlet head 7, and the liquid outlet head 7 is arranged at the liquid outlet end of the liquid outlet pipe 11; during operation, drive play liquid case 6 rotation in the liquid head 7 through rotating liquid head 7, can realize opening or closing of liquid pipe 11 play liquid, compare with current liquid pipe 11 of opening for a long time, both ensured clean, have avoided pressure influence to lead to liquid reflux in liquid pipe 11 or the reservoir 12 in the bottle, and then need press many times and just can go out liquid when leading to reuse.

A connecting pipe 8 extending into the bottle bottom is arranged in a communicating groove communicated with the liquid storage tank 12 and the connecting ring 14; when the prepressing piston 21 is driven to reset under the action of the elastic component 24, negative pressure is formed in the liquid storage tank 12 to generate suction force, and the suction force can convey liquid in the bottle into the liquid storage tank 12 through the connecting pipe 8 to supplement the liquid amount in the liquid storage tank 12.

It should be added that, since the elastic member 24, whether it is a spring or a U-shaped elastic sheet, is disposed outside without contacting with the liquid, compared with the conventional pre-pressing gun with an internal spring, the liquid is prevented from reacting with the spring.

The outer side of the connecting ring 14 is provided with a thread seat 9 connected with the bottle body; during operation, the connection of the pre-pressing gun and the bottle body is realized through the threaded seat 9.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
