Description

A kind of novel pistol pump

[technical field]

The utility model relates to a kind of pistol pump.

[background technology]

Existing pistol pump is used more extensive in daily life, and aspect such as be mainly used in hair washing, take a shower, water flowers is used more convenient, very popular.Yet the sprinkler cap of existing pistol pump and shell are one, like this when sprinkler cap damages, and the sprinkler cap that can not more renew not only, and also whole pistol pump also can not use; In addition, existing pistol pump can only be one type, or is atomizing, or is foam type, uses the comparison dullness, and in order to address the above problem, the inventor designs the utility model.

[utility model content]

The utility model has overcome the deficiency of above-mentioned technology, and a kind of pistol pump that can change sprinkler cap is provided.

For achieving the above object, the utility model has adopted following technical proposal:

A kind of novel pistol pump includes the shell and the setting pump housing in the enclosure, is provided with water intaking valve in the feed pathway of the pump housing; Piston and back-moving spring are housed in the pressure channel of the pump housing, but on shell, are hinged with the spanner that a driven plunger moves forward and backward; Be provided with outlet valve in the liquid outlet channel of the pump housing, in the exit of liquid outlet channel shower nozzle be housed, be provided with a dismountable nozzle cap at the front end of shower nozzle, nozzle cap is provided with fluid hole.

Described outlet valve is shaft-like check valve, is provided with conical valve block around the outlet valve, the taper seat of conical valve block backwards, conflict on the liquid outlet channel inwall of the pump housing in the edge of conical valve block.

Be provided with the flange to convex on nozzle cap, shower nozzle is provided with the cambered outwards convex tendon that cooperates to the flange of convex with nozzle cap.

The sliding seat that is moved forward and backward by the spanner promotion is housed in the pressure channel of the pump housing, and described piston is fixed on the sliding seat rear end.

Compared with prior art, the beneficial effects of the utility model are:

1, because nozzle cap can disassemble, just can realize the effect of spraying or spraying foam by changing nozzle cap like this.2, owing to be provided with conical valve block around the outlet valve, make that like this sealing effectiveness of the pump housing is better.

Fig. 2 is the profile of embodiment 1 of the present utility model;

Fig. 3 is the stereogram of embodiment 2 of the present utility model;

Fig. 4 is the structural representation that is installed on the bottle of the present utility model.

[specific embodiment]

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:

Referring to Fig. 1-4, the utility model is that a kind of novel pistol pump includes the shell 1 and the pump housing 2 that is arranged in the shell 1, is provided with the feed pathway, pressure channel, the liquid outlet channel that communicate in the pump housing 2.Be provided with water intaking valve 3 in the pump housing 2 feed pathway, water intaking valve 3 includes water valve rod into 31 and is arranged on pump pearl 32 on the water valve rod 31 into, is provided with passage in the water inlet valve rod 31, and pump pearl 32 can unidirectionally be sealed passage, and water inlet valve rod 31 lower ends are connected with lock bottle cap 4; Sliding seat 5 is housed in the pressure channel of the pump housing 2, is fixed with piston 6, between the piston 6 and the pump housing 2, be provided with back-moving spring 7, on shell 1, be hinged with one and can drive the spanner 8 that sliding seat 5 moves forward and backward in sliding seat 5 rear ends; Be provided with outlet valve 9 in the liquid outlet channel of the pump housing 2, in the exit of liquid outlet channel shower nozzle 10 be housed, be provided with a dismountable nozzle cap 11 at the front end of shower nozzle 10, nozzle cap 11 is provided with fluid hole.Because nozzle cap 11 can disassemble, just can realize the effect of spraying or spraying foam by changing nozzle cap like this.

Embodiment 1:

Referring to Fig. 1-2, nozzle cap 11 is aerosol lid, has the pistol pump of this lid, and the liquid that comes out will nebulize.

Embodiment 2:

Referring to Fig. 3, nozzle cap 11 is the lid of spray foam type, has the pistol pump of this lid, and the liquid that comes out will become foam-like.

Described outlet valve 9 is shaft-like check valve, is provided with conical valve block 91 around the outlet valve 9, the taper seat of conical valve block 91 backwards, conflict on the liquid outlet channel inwall of the pump housing 2 in the edge of conical valve block 91.Owing to be provided with conical valve block 91 around the outlet valve 9, make that like this sealing effectiveness of the pump housing 2 is better.

In the utility model, adopt the bayonet socket connected mode between nozzle cap 11 and the shower nozzle 10, be provided with the flange 12 to convex on nozzle cap 11, shower nozzle 10 is provided with the cambered outwards convex tendon 13 that cooperates to the flange 12 of convex with nozzle cap 11.Can certainly adopt thread connecting mode or other connected mode.

Operation principle of the present utility model is as follows: the space that forms sealing between water intaking valve, outlet valve, piston and the pump housing, push spanner 8, the volume-diminished of enclosure space is discharged through outlet valve after the gas compression, decontrols spanner 8, effect lower piston 6 returns at back-moving spring 7, the volume of enclosure space increases suddenly, thereby causes parital vacuum, by the effect of external atmosphere pressure the liquid in the bottle is passed through in the water intaking valve suction pump, repeatedly by, put and press spanner 8 several times, enclosure space will be full of liquid.Push spanner 8 once more, because of the Incoercibility of liquid, liquid will be discharged from outside the pump by outlet valve, form vaporific or foam-like.
