Abstract
The utility model discloses a novel pump comprising a pump body, wherein the pump body is internally provided with a cavity; one end of the pump body is provided with a liquid inlet and the pump body is internally provided with a hollow piston rod with a piston; one end of the piston rod is closed; the rod body at the closed end of the piston rod is provided with an opening communicated with the cavity and the hollow piston rod; the other end of the piston rod is provided with a pressure head; and the lower end of the pump body is provided with a return spring and a one-way valve. The utility model aims at overcoming the defects in the prior art and provides a novel pump which has simple structure and good sealing effect and is convenient to use.
Description
[technical field]
The utility model relates to a kind of new pump.
[background technology]
Existing emulsion form object as shampoo, shower cream etc., generally is encapsulated in the reservoir, takes emulsion for the convenience of the users, and the emulsion pump generally is installed on the reservoir, and the user is by pushing pressure head, and the emulsion in the storage liquid pump will be from the nozzle ejection of pressure head.But many, the complex structure of existing its part of emulsion pump, the big and production cost height of manufacture difficulty; And because existing its sealing of emulsion pump is not so good, thereby cause its fluid effect bad.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art, provides a kind of simple in structure, good sealing effect, new pump easy to use.
The utility model is achieved through the following technical solutions:
A kind of new pump, comprise the pump housing, in the pump housing, be provided with cavity, on the described pump housing one end, be provided with inlet, be provided with the hollow piston rod of a band piston in the described pump housing, described piston rod one end seals, and is provided with the opening of a described cavity of connection and hollow piston rod on the body of rod of described its blind end of piston rod, on the described piston rod other end, be provided with pressure head, be provided with back-moving spring and check valve in described pump housing lower end.
Aforesaid a kind of new pump, it is characterized in that the described pump housing comprises upper pump casing and lower pump body, the diameter of described upper pump casing is bigger than the diameter of lower pump body, be provided with the ring block that can seal described lower pump body on its blind end of described piston rod, described opening is arranged on the bar wall between ring block and the piston.
Aforesaid a kind of new pump is characterized in that described back-moving spring is arranged in the lower pump body, and described back-moving spring one end roof pressure is on the ring block bottom, and back-moving spring other end roof pressure is on the limited step of lower pump body.
Aforesaid a kind of new pump is characterized in that described check valve is a ball, is provided with a step in the lower pump body below described back-moving spring, and described ball is arranged on the step.
Compared with prior art, the utility model has following advantage:
Piston-rod lower end sealing in the utility model, on the body of rod of blind end, be provided with piston rod in the import of channel connection, on the body of rod of blind end, also be provided with the ring block that can seal lower pump body, improved the sealing property of the pump housing, the user is in press head, and only needs are several lightly down, just can the liquid in the bottle be extracted out, fluid is effective, and is easy to use.
[description of drawings]
Fig. 1 is the generalized section of the utility model when closing;
Generalized section when Fig. 2 the utility model is opened.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of new pump shown in Fig. 1 to 2, comprise the pump housing 1, in the pump housing 1, be provided with cavity 9, on the described pump housing 1 one ends, be provided with inlet 8, be provided with the hollow piston rod 3 of a band piston 2 in the described pump housing 1, described piston rod 3 one ends seal, and are provided with the opening 4 of described cavity 9 of a connection and hollow piston rod 3 on the body of rod of described piston rod 3 its blind ends, on described piston rod 3 other ends, be provided with pressure head 7, be provided with back-moving spring 6 and check valve 5 in the described pump housing 1 lower end.
The pump housing 1 described in the utility model comprises upper pump casing 11 and lower pump body 12, the diameter of described upper pump casing 11 is bigger than the diameter of lower pump body 12, be provided with the ring block 31 that can seal described lower pump body 12 on described piston rod 3 its blind ends, described opening 4 is arranged on the bar wall between ring block 31 and the piston 2.Wherein said back-moving spring 6 is arranged in the lower pump body 12, and described back-moving spring 6 one end roof pressures are on ring block 31 bottoms, and back-moving spring 6 other end roof pressures are on the limited step 121 of lower pump body 12.
The utility model product generally is to be used in shampoo, in the reservoirs such as shower cream, the pump housing and bottle seal setting, the user is in flicking pressure head 7, piston rod 3 drives piston 2 and moves down, air in the pump housing 1 is discharged to the external world by the opening 4 that is arranged on the piston rod 3 bottom bodies of rod, when piston rod 3 moves down into maximum position, be arranged on piston rod 3 lower annular pieces 31 and can seal lower pump body 12, make and produce negative pressure in the lower pump body 12, ball in the process of moving on piston rod 3 below the lower pump body 12 can be pushed open by the liquid in the bottle and enter lower pump body 12, along with piston moves on continuing, liquid enters upper pump casing 11, enters passage in the piston rod 3 by opening 4 then, flow out from the nozzle of pressure head 7, adopt piston 2 and ring block 31 dual-seals in the utility model, improved the drawing liquid effect greatly, for the user provides convenience.
