Abstract
The utility model discloses a vacuum pump, which comprises a shielding cover, a bottle body, a bottom cover, a piston body, a press cap with a nozzle, a base ring and a plastic pump, wherein the base ring is fixed on the bottle body, the piston body is installed in the bottle body, the bottom cover is fixed at the bottom of the bottle body, and the press cap with the nozzle is connected with the plastic pump and telescopically installed in the base ring. The vacuum pump is characterized in that a spring is arranged between the bottom end of the press cap with the nozzle and the base ring. The top surface of the press cap with the nozzle is provided with an inclined finger pressing curved surface. The vacuum pump enables pressing components to return quickly, is particularly suitable for liquid with large viscosity, and has the advantages of being low in cost and simple in structure.
Description
Technical field
The utility model relates to the vacuum pump technology field, is a kind of vacuum pump that is used for frost or emulsion specifically.
Background technology
In cosmetics or slim product field; usually can use vacuum pump; as shampoo; slimming creams etc. have the liquid of certain denseness; as the Chinese patent patent No. is 200720115229.5 1 kinds of emulsion vacuum pumps; this vacuum pump structure is simple and practical; parts are few and with low cost; easy to use; but this pump is used for shampoo; when slimming creams etc. have the liquid of certain denseness; the big liquid of viscosity particularly; the pressure cap of band nozzle is difficult to fast quick-recovery; want smoothly; fast quick-recovery; certainly will to increase the elastic restoring force of plastic cement pump, promptly must improve plastic cement pump performance and material requirements, be equivalent to increase indirectly manufacturing cost like this.
Summary of the invention
The purpose of this utility model provides a kind of pressing component and resets fast, be specially adapted to the big liquid of viscosity, and cost is low, vacuum pump simple in structure.
A kind of vacuum pump, the pressure cap, seat ring, the plastic cement pump that comprise cover cap, bottle, bottom, piston body, band nozzle, seat ring is fixed on the bottle, piston body is installed in the bottle, bottom is fixed on the bottom of bottle, the pressure cap of band nozzle is connected with the plastic cement pump and telescopic being installed in the seat ring, it is characterized in that: be provided with spring between the bottom of the pressure cap of described band nozzle and the seat ring.
The end face of the pressure cap of described band nozzle is provided with bevelled finger presses curved surface.
Described finger presses curved surface is provided with anti-skidding salient point.
The utlity model has following advantage:
The utility model is owing to be provided with spring between the bottom of pressure cap of band nozzle and seat ring, pressure cap when the band nozzle, seat ring, when the liquid cavity that the plastic cement pump constitutes is full of the sticking liquid of the big liquid of viscosity or other, finger presses down after pressure cap ejection liquid unclamps finger again, under the effect of the elastic force of spring, pushing away with the pressure cap of nozzle up, return to the state that is not pressed down very soon, if there is not spring, under the effect of the big liquid of viscosity or other sticking liquid, when the recovery elasticity of plastic cement pump can not overcome this resistance, the pressure cap of band nozzle can't restore or fast release, directly have influence on the operation that presses down for the second time and make liquid be difficult to pump, serious might normal operation, and the utility model does not need from improving the reseting performance of plastic cement pump, just can address the above problem is the quick reset issues of pressing component, does not promptly need to improve plastic cement pump performance and material requirements, is equivalent to reduce indirectly manufacturing cost like this.
Because the end face of the pressure cap of band nozzle is provided with bevelled finger presses curved surface, can do pressure cap higher like this, make pressure cap stroke increase up and down, help the increasing of the liquid cavity in the vacuum pump, once Pen Chu amount of liquid is big, if do not take this structure, when then increasing pressure cap, promptly stroke increases about the pressure cap, certainly will influence the comfort level of people's use, because people's finger length is different, and pressure cap has increased, and the people that short hand refers to reaches or will seek the handshake part again, uses very trouble, so can not satisfy the use of different people, and structure of the present utility model has solved this problem.
Description of drawings
Fig. 1 is the utility model vacuum pump block diagram;
Fig. 2 is the utility model vacuum pump structure scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model vacuum pump seat is further specified.
Among Fig. 1-2, the utility model vacuum pump, the pressure cap 1, seat ring 3, the plastic cement pump 2 that comprise cover cap 6, bottle 4, bottom 8, piston body 5, band nozzle, seat ring 3 is fixed on the bottle 4, piston body 5 is installed in the bottle 4, bottom 8 is fixed on the bottom of bottle 4, and the pressure cap 1 of band nozzle is connected with plastic cement pump 2 and telescopic being installed in the seat ring 3, is provided with spring 9 between the bottom of the pressure cap 1 of being with nozzle and seat ring 3.The end face of the pressure cap 1 of band nozzle is provided with bevelled finger presses curved surface 11, and finger presses curved surface 11 is provided with anti-skidding salient point 12.Wherein the local structure between the pressure cap 1 of bottle 4, bottom 8, piston body 5, band nozzle, seat ring 3, plastic cement pump 2 each parts constitute pump suction structure, and the pump-absorb action of finishing vacuum pump belongs to prior art, and plastic cement pump 2 also can be the suction pump of other type.Inventive point of the present utility model is exactly the fast speed purpose that resets that solves the pressure cap 1 of band nozzle.
The utility model principle of work is as follows: when using vacuum pump, as long as with hand pressure cap 1, make pressure cap 1 overcome the elastic force of spring 9 and plastic cement pump 2, move downward, the liquid cavity 7 between pressure cap 1 and the plastic cement pump 2 is diminished, the pressure of liquid cavity 7 just increases, simultaneously, plastic cement pump 2 is subjected to downward pressure, and the distortion of certain elastic deformation and corresponding construction takes place, and makes liquid ejection in the liquid cavity 7 and the nozzle ejection by pressure cap l; When openhanded opening, pressure cap 1 resets under the resilient force of spring 9 and plastic cement pump 2, upward movement makes the liquid cavity 7 between pressure cap 1 and the plastic cement pump 2 increase the pressure decay in the liquid cavity 7, corresponding structure changes, liquid supplementary sum in the bottle 4 is drawn in the top liquid cavity 7, for ejection is once got ready, like this, circulation just makes vacuum pump constantly spray liquid successively.
