Technical field

The present invention relates to pump technical field more particularly to extrusion pumps.

Background technique

Operation strategies are very extensive, and are customarily used in the product scopes such as lotion for extrusion pump (extrusion pumps of such as various lotions), In order to which lotion is squeezed out out of extrusion pump.And there are following defects for existing extrusion pump:

1, it after extrusion pump is equipped with lotion and use, is not easy to carry, because being easy squeeze buttons in carrying process makes Liquid sprays.

2, when the lotion in extrusion pump is less, it is easy to cause empty spray (adulterating large quantity of air when spraying), is used It is inconvenient.

3, it is difficult to control the amount for spraying lotion every time.

Summary of the invention

For overcome the deficiencies in the prior art, the purpose of the present invention is to provide extrusion pump, it is not easy to reveal lotion thus It is easy to carry, and empty spray is also not easy when the lotion in extrusion pump is less, and spray the amount of lotion every time convenient for control.

The purpose of the present invention adopts the following technical scheme that realization:

Extrusion pump, including shell, diversion pipe and closeouts；

The shell has inner cavity, and the inner cavity is for accommodating lotion, and the shell offers inlet opening and fluid hole, institute The both ends for stating inlet opening and fluid hole are switched to inner cavity and external environment respectively；One end of the closeouts removably blocks Inlet opening, the other end removably block fluid hole；

The shell is also provided with accommodating chamber, and cage connection has diversion pipe, and one end of the diversion pipe and fluid hole connect It connects, the other end is switched to the inner cavity；The diversion pipe includes savings section, and the savings section is located in accommodating chamber, the savings Duan Caiyong elastic material is made, and the savings section squeezes the lotion saved in section to fluid hole or decompression for compressive deformation And it restores to the original state；At least two normally close valves made of elastic material are equipped in the diversion pipe, the savings section is set to two Between the normally close valve；When the savings section compressive deformation, the normally close valve is by air pressure or hydraulic and open, when the savings Section decompression and when restoring to the original state, the normally close valve restores to the original state and blocks diversion pipe.

Further, one end of the diversion pipe is connect with fluid hole, and the other end penetrates accommodating chamber from inner cavity, then from receiving Chamber is penetrated to inner cavity to connect the inner cavity.

Further, the normally close valve includes two pieces of sealing blocks being symmetrically set, and two pieces of sealing blocks can be mutual It squeezes to block the diversion pipe or be located remotely from each other to open the diversion pipe.

Further, two pieces of sealing blocks are arranged with the axis of the diversion pipe in angle, and the sealing block is certainly The inner wall of the diversion pipe extends to lotion from the direction inclination that inner cavity flows out to fluid hole.

Further, the diversion pipe further includes the first pipeline section and the second pipeline section, the both ends of the savings section respectively with institute The first pipeline section and the connection of the second pipeline section are stated, and first pipeline section is connect with fluid hole, the second pipeline section is switched to inner cavity.

Further, first pipeline section, savings section and the second pipeline section are detachably connected between any two, and first pipe Section and the second pipeline section are all made of elastic material and are made.

Further, the savings section is contacted with the bottom wall of the accommodating chamber of the shell, and by the bottom wall of the accommodating chamber Bearing.

Further, the extrusion pump further includes button, and the button is slidably connected the side wall of the accommodating chamber, and with institute Savings section contact is stated, the button is for squeezing the savings section.

Further, the side wall of the accommodating chamber offers stroke limit slot, and the button is equipped with buckle, and the buckle is slided It is dynamic to connect the stroke limit slot so that the button be moved along the direction close to or far from the savings section, and by described Stroke limit slot is limited.

Further, the cylindrical flat structure of the shell, the diversion pipe are of an L-shaped structure, the diversion pipe First pipeline section, savings section and the second pipeline section composition vertical section and horizontal segment；The fluid hole is set to the top of the shell, described The axis collinear of the axis of vertical section and the fluid hole, the savings section are set to the horizontal segment.

Compared with prior art, the beneficial effects of the present invention are:

1, extrusion pump of the invention squeezes savings section, due to extruding force after filling lotion in savings section each time backward Act directly in lotion, i.e., squeeze and all effectively act on extruding force in lotion each time, and by lotion squeeze out to External environment can prevent empty spray phenomenon, use very convenient.

2, moreover, because the compression degree of savings section is directly controlled by manpower, thus the amount for needing to spray lotion can be by Manpower control.

3 also, inlet opening and fluid hole are blocked respectively by the both ends of closeouts, since inlet opening is seldom opened, thus Closeouts can frenulum on the shell, be not easy to lose, hereby it is ensured that fluid hole can be blocked, so that this extrusion pump is not easy to reveal Lotion and it is easy to carry.
