Abstract

The utility model relates to an emulsion pump. In the prior pump, the problem that the environment is polluted and the emulsion is wasted is solved. As soon as the bottle is inversed in the transportation process, the emulsion can be brought out of the bottle when a pressing head is opened. The emulsion in the gap of the body 12 and the main post 3 is brought by the main post 3 from the gap between the main post 3 and the big spiral tooth 4. The emulsion pump comprises a pressing head, a climbing pearl, a main post, a big spiral tooth lock, a spiral tooth, a piston, a subsidiary post, a spring, a main body, a downgrade pearl and a sucker. A subsidiary locked cock is arranged on the upper part in the body. An outer diameter of the subsidiary locked cock is slide and coordinated with the inner diameter of the body. A through hole slide and coordinate with the outer diameter of the main body is arranged at the center of the subsidiary locked cock. The subsidiary locked cock plugs up the air vent on the body before the pressing head and the big spiral tooth lock. After the pressing head and the big spiral tooth lock are separated, the main post jacks upward the subsidiary locked cock and the air vent on the body is opened. Wherein, the resistance force between the subsidiary locked cock and the body is more than the resistance force between the subsidiary locked cock and the main post.

Description

The emulsion pump

Technical field:

The utility model relates to a kind of emulsion pump, particularly a kind of emulsion pump that is used for doing on the lotion pumps such as shower cream or shampoo the extraction emulsion.

Technical background:

The existing emulsion pump configuration that is used for doing on the lotion pumps such as shower cream or shampoo extracting emulsion comprises head 1, goes up bead 2, principal post 3, big thread lock 4, thread 7, piston 9, subpost 10, spring 11, body 12, bead 13 and suction pipe 14 down as shown in Figure 5; Wherein the outside thread of thread and lotion pump bottleneck matches, during use head 1 rotation is made it to separate with big thread lock 4, subpost 10 drives piston 9 upward movement together under the effect of spring 11, produce negative pressure in the cavity in the body 12 between piston 9 and the following bead 13 and bead 13 is upwards opened, last bead 2 is closed the upper shed of principal post 3, and the emulsion in the lotion pump is inhaled into body and produces in the cavity of negative pressure; When piston 9 by after the jack-up fully, as depress head 1 piston 9 moved downward, lower pellet 13 is closed the under shed of body 12, last bead 2 is by the top and opening upwards of the emulsions in the body 12, emulsion sprays from the exit of head 1; When long-term use because of bottle in the minimizing of emulsion, so must have ventilation orifice 8 on body 12 tops bottle internal cavity is communicated with atmosphere by the gap between principal post 3 and the big thread lock 4, otherwise bottle in will produce vacuum and make bottle deforms.

There is following shortcoming in above-mentioned existing emulsion pump, when manufacturer accomplishes fluently after the can emulsion in bottle in this section process of packing when the customer locks the big thread of head rotation disengaging, may be during because of carrying with bottle upsidedown, emulsion is promptly in the space 15 that ventilation orifice 8 flows between body 12 and the principal post 3 in the bottle, rotation head 1 makes it to break away from big thread lock 4 during unlatching, emulsion between body 12 and the principal post 3 in the space will be taken out of outside the bottle by principal post 3 along the gap of 4 on principal post 3 and big thread lock, not only contaminated environment but also wasted emulsion.

Summary of the invention:

Technical matters is if even the purpose of this utility model is to lock 4 gap from principal post 3 and big thread and environment is polluted and wastes the problem of emulsion and provides a kind of and transportation bottle upsidedown can not polluted or waste the emulsion pump of emulsion to environment yet outside being taken out of by principal post 3 bottle in order to solve the emulsion in the space between transportation will cause bottle upsidedown when opening head body 12 and principal post 3 that exists in the existing emulsion pump.

Technical scheme:

The purpose of this utility model is achieved in that a kind of emulsion pump, comprises head, last bead, principal post, big thread lock, thread, piston, subpost, spring, body, following bead and suction pipe; It is characterized in that being provided with on intrinsic top the secondary locked cock of an external diameter and body internal diameter bearing fit, secondary locked cock center has the through hole with principal post external diameter bearing fit; Secondary locked cock is blocked the ventilation orifice on the body before head and big thread lock separate, and head separates afterwards with big thread lock that principal post makes progress jack-up with secondary locked cock and the ventilation orifice on the body is opened; Resistance between wherein secondary locked cock and the body is greater than the resistance between secondary locked cock and the principal post.

Described emulsion pump, it is characterized in that secondary locked cock is provided with a pipe that extends upwardly, head be provided with secondary locked cock on presenting a theatrical performance as the last item on a programme of matching of pipe, presenting a theatrical performance as the last item on a programme just secondary locked cock shifted when head is threaded in the big thread lock when assembling emulsion pump on the head blocked the ventilation orifice on the body.

Beneficial effect, owing to adopted technical scheme described in the utility model, secondary locked cock is blocked the ventilation orifice on the body before head and big thread lock separate, even at this moment with the lotion pump reversing, the interior emulsion of bottle can not flow in the space between principal post and the body yet; Be earlier lotion pump to be placed by correct placement direction when needs use, when separating with big thread lock, head do not have emulsion because of the space between principal post and body, so not having emulsion is taken out of between principal post and big thread lock, and head separates the back principal post and secondary locked cock is made progress jack-up and the ventilation orifice on the body is opened with big thread lock, and emulsion pump at this moment is the same with common emulsion pump.Even therefore the problem of emulsion just can not take place environment is polluted and wastes with bottle upsidedown in emulsion pump described in the utility model in transportation

Description of drawings:

Fig. 1 is the inner structure scheme drawing of emulsion pump described in the utility model.

To be the described emulsion pump of Fig. 1 be locked in the scheme drawing of big thread when locking at head to Fig. 2.
