[0013] 1. The present invention first installs a bearing seat at the position where the spring is installed at the bottom of the inner cavity component, which assists in achieving the supporting effect of the bearing seat on the spring, and the driving component slides in the inner cavity component. The one-way ball of the inner cavity component and the one-way plate of the driving component together form a two-way one-way conduction structure to realize the use of the pump body device. The top external pipe of the driving component is directly connected to the external component. The outer end of the external pipe is vertically slidably installed with a lifting component. The outer end of the lifting component is screwed with a control sleeve, so that the control sleeve can be rotated to realize the descent control of the lifting component. The descending lifting component can push the driving component downward, so that the sliding space of the driving component in the inner cavity component is reduced, and the control component is rotated to control the amount of emulsion extracted by the driving component sliding in the inner cavity component. The control component has the function of controlling the adjustment float while fixing the device as a whole.

[0014] Second, the present invention directly sets a circular array of control surfaces on the exposed portion of the upper end of the control component, so that after the control component is rotated, the outer end of the control outer block can better correspond to the control surface, so that after the control outer block is in contact with the control surface, better control of the rotation and floating can be achieved, thereby helping to control the overall discharge of emulsion by the control surface control device.

[0015] 3. A bearing seat is installed at the bottom of the inner cavity of the present invention near the one-way ball. The bearing seat is set to an annular structure, so that the bearing seat can better bear the spring. Usually, the spring is mostly made of metal, so that the bearing seat can bear the spring while avoiding the spring from causing damage to the bottom of the inner wall of the inner cavity. The bearing seat also prevents the one-way ball from getting stuck, allowing the one-way ball to have a better floating effect.

[0016] 4. Two sets of one-way plates are installed at the bottom of the inner slider of the present invention, which allows the emulsion to be poured in better through the one-way plates. The guide outer grooves provided on the outer wall of the inner slider correspond to the inner wall of the inner cavity, so that the inner slider can slide axially in the inner cavity, and at the same time, the inner slider is fixed circumferentially. The vertical external tube provided at the top of the inner slider is convenient for external connection components, and at the same time, the lifting component can be installed on the outer wall of the external tube. The outer groove of the external tube allows the installation of the lifting component to only have axial sliding, forming circumferential positioning, so that the lifting component of the control component can stably squeeze the driving component downward after it descends, thereby realizing the control of the entire device in extracting the emulsion.

[0017] 5. The control sleeve at the outer end of the lifting assembly of the present invention is configured to be screwed and installed, so that after rotating the control sleeve, the lifting assembly is driven downward by the spiral wall, thereby achieving the downward squeezing of the driving assembly by the lifting assembly, thereby achieving the control of the extraction amount of the driving assembly. The shape at the outer terrace is convenient for the snap-on installation of the control outer block, allowing the control outer block to conveniently control the control assembly.

[0018] 6. An auxiliary component is rotatably installed at the end position of the outlet of the external component of the present invention, wherein the exposed ring is connected to the spiral sheet, and the spiral sheet has a spiral structure, so that the emulsion can be stably discharged from the spiral sheet position. After some emulsions are exposed to the air for a long time, the emulsion will be dehydrated and air-dried. Therefore, the spiral sheet is installed at the outlet position of the external component to reduce the contact of the emulsion remaining at the auxiliary component position with the external air, thereby avoiding the problem of the emulsion drying out.
