Abstract

This utility model relates to a atomizing pump which the structure is simple and can be used upside down, including the head, screw tooth, main body, principal post, sub-post, suction tube, upper non-return valve and lower non-return valve; one auxiliary body is also included, the lower end of this auxiliary body is connected with the suction tube, the auxiliary body is provided with conical surface which is matched with glass ball; the valve cover is fixed at the position above conical surface in the auxiliary body, the upper part of this valve cover is provided with the upside down conical surface which is matched with lower glass ball; the lower part of main body sleeves the upper part of valve cover and the outer post surface of upper part of valve cover is provided with axial groove; the upper part of auxiliary body sleeves the main body and gap is provided between them, so that the inner cavity of main body can be connected with bottle body through the axial groove on the valve cover and gap between main body and auxiliary body.

Description

Atomizing pump

Technical field

The utility model relates to a kind of atomizing pump.

Background technology

The atomizing pump that uses in the beauty treatment chemical products such as existing hair jelly comprises head, thread, body, principal post, subpost, suction pipe and last check valve, following check valve, wherein principal post and subpost and body match and become plunger-type structure, last check valve and following check valve are separately positioned on the body top and bottom, when pushing head repeatedly, principal post and subpost are done upper and lower moving and by suction pipe liquid in the bottle are sucked body with respect to body with head, the ejection of the spray orifice on head then; The suction pipe of this atomizing pump is plugged in the body lower end, at the bottom of its suction pipe suction inlet stretches into bottle, is inverted in case its shortcoming is a bottle, then can not normally use.

Summary of the invention

The purpose of this utility model is the problem that can not be inverted use that exists in the existing atomizing pump in order to solve, and provide a kind of simple in structure, can be inverted the atomizing pump of use.

Technical scheme:

The purpose of this utility model is achieved in that a kind of atomizing pump, comprise head, thread, body, principal post, subpost, suction pipe and last check valve, following check valve, it is characterized in that also comprising an accessory body, this accessory body lower end and described suction pipe join, be provided with the conical surface that matches with following bead in the accessory body, the position that is positioned in described accessory body above the conical surface is fixed with valve pocket, this valve pocket top is provided with the inverted conical surface that matches with described bead down, described body lower end is entangled cover top, the Yan and is provided with axial groove on the outer cylinder surface on valve pocket top, described accessory body top be enclosed within described external and leave the gap between the two, chamber body can be communicated with bottle with gap between the accessory body by the axial groove on the described valve pocket and body.When forward uses, because the gap between axial groove on the valve pocket and accessory body and the body is less, ejection again after atomizing pump can suck liquid in the bottle by suction pipe, and in case be inverted, following bead is positioned at the inversion conical surface of valve pocket, can prevent that the air in the bottle from entering body when chamber body produces negative pressure, and body can only suck by the liquid of the axial groove outside the gap between body and the accessory body, the valve pocket with bottle mouth position, ejection has again realized being inverted the function of using.

Beneficial effect:

Owing to adopted technical scheme described in the utility model,, enlarged the function of use of atomizing pump even the bottle inversion of having installed behind this atomizing pump also can be used.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the internal structure schematic diagram of an embodiment of atomizing pump described in the utility model.

Fig. 2 be among Fig. 1 along A---the profile of A line.

Fig. 3 be among Fig. 1 body and valve pocket along B---the profile of B line.

Among the figure 1, head, 2, principal post, 21, conical head, 3, thread, 4, subpost, 5, body, 7, valve pocket, 8, bead down, 9, suction pipe, 601, the conical surface, 701, the conical surface, 6, accessory body, 52, spring, 51, piston, 41, go up bead, 401, side opening, 201, mesopore, 101, spray orifice, 50, axial ribs, 500, the gap, 70, axial groove.

The specific embodiment:

See Fig. 1, described atomizing pump, comprise head 1, thread 3, body 5, principal post 2, subpost 4, suction pipe 9 and the following check valve that constitutes by the conical surface in the accessory body 6 601 and following bead 8, the last check valve that constitutes by piston 51 upper ends and last bead 41, accessory body 6 lower ends and suction pipe 9 join, the position that is positioned in accessory body 6 above the conical surface 601 is fixed with valve pocket 7, valve pocket 7 tops are provided with the inverted conical surface 701 that matches with following bead 8, body 5 lower ends are entangled valve pocket 7 tops and are provided with axial groove 70 (see figure 3)s on the outer cylinder surface on valve pocket 7 tops, accessory body 6 tops are enclosed within outside the body 5, make between body 5 inwalls and accessory body 6 inwalls and leave gap 700 (see figure 2)s being provided with six axial ribs 50 on the inwall of body 5.

Be inverted when using, following bead 8 is positioned at the inversion conical surface 701 of Yan cover, after depressing head 1 and unclamping then, body 5 inner chambers can prevent when producing negative pressure that the air in the bottle from entering body through suction pipe 9, and body can only be by the gap 500 (Fig. 2) between body 5 and the accessory body 6, axial groove 70 (Fig. 3) outside the valve pocket sucks the liquid of bottle mouth position in the body, when depressing head once more, following bead 8 withstands the conical surface 601, under the interior pressure effect of body, intrinsic liquid backs down the side opening 401 of bead 41 on subpost 4 and enters inner chamber place, body 5 top, simultaneously subpost 4 overcomes the power of spring 52 and conical head 21 is separated with mesopore 201 on the principal post 2, through spray orifice 101 ejections, realized being inverted the function of using again.

Claims

1, a kind of atomizing pump, comprise head, thread, body, principal post, subpost, suction pipe and last check valve, following check valve, it is characterized in that also comprising an accessory body, this accessory body lower end and described suction pipe join, be provided with the conical surface that matches with following bead in the accessory body, the position that is positioned in described accessory body above the conical surface is fixed with valve pocket, this valve pocket top is provided with the inverted conical surface that matches with described bead down, described body lower end is entangled valve pocket top and is provided with axial groove on the outer cylinder surface on valve pocket top, described accessory body top be enclosed within described external and leave the gap between the two, chamber body can be communicated with bottle with gap between the accessory body by the axial groove on the described valve pocket and body.
