It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a festival volume emulsion pump, as shown in fig. 1-5, including pump head 100, adjusting collar 200, water conservancy diversion push rod 300, lid 400, pump package spare 500. One end of the guide push rod 300 is connected to the pump head 100, and the other end is connected to the pump assembly 500 in the cover 400, so that pressing the pump head 100 can drive the pump assembly 500 to eject the emulsion (not shown) in the bottle (not shown) through the guide push rod 300 and the pump head 100. Pump assembly 500 includes pump chamber 510, reinforcing vanes 520, fluid inlet tube 530, and fluid inlet 540, fluid inlet 540 being positioned below the level of the emulsion in the bottle, fluid inlet tube 530 directing the emulsion through fluid inlet 540 into pump chamber 510, reinforcing vanes 520 preventing fluid pressure from deforming pump assembly 500 and affecting the ejection of the emulsion. The cover 400 includes a locking cover 410 and a bottle cap 420, wherein the bottle cap 420 fixes the whole of the quantitative emulsion pump and the bottle body through the screw connection and other modes, and realizes the sealing of the bottle body, thereby preventing the emulsion in the bottle body from flowing out after the bottle body turns over. The adjustment sleeve 200 may be connected to the pump head 100, such that the adjustment sleeve 200 is disposed between the pump head 100 and the cover 400, or may be disposed between the pump head 100 and the cover 400 via other auxiliary devices. The distance between the adjusting sleeve 200 and the pump head 100 can be continuously adjusted by moving the adjusting sleeve 200, the adjusting sleeve 200 can be moved in a thread, buckle or the like, and the distance can be kept fixed through structures such as a thread self-lock, a clamping bolt or a clamping groove, a movable pin and the like. The pump head 100 can drive the pump assembly 500 to eject the emulsion in the bottle through the liquid outlet 130, the pump head 100 discharges the air in the pump chamber 510 by lowering the height of the guide push rod 300 and working through a piston (not shown in the figure) and a valve (not shown in the figure) in the pump chamber 510, the guide push rod 300 and the piston rise back in height under the action of a spring (not shown in the figure) to form negative pressure to suck the emulsion in the bottle into the pump chamber 510, and after the pump head 100 is continuously pressed, the emulsion passes through the guide push rod 300 and the pump head 100 to be ejected out of the liquid outlet 130. The pressing stroke of the pump head 100, i.e., the height at which the pump head can be lowered by pressure, is positively correlated with the discharge amount per one stroke of the lotion pump. The maximum pressing stroke of the pump head 100 is the maximum height at which the pump head 100 can be lowered once after being pressed, i.e., the maximum height variation of the pump head 100 under one pressing action, and the size of the pressing stroke of the pump head 100 determines the amount of the emulsion ejected once from the bottle. When the distance between the adjusting sleeve 200 and the pump head 100 is reduced or increased, the maximum pressing stroke of the pump head 100 can be correspondingly increased or reduced, the maximum liquid spraying amount of the saving lotion pump is increased or reduced, and the saving lotion pump is in an adjusting state. As shown in fig. 1, the third drawing of fig. 3, the second drawing of fig. 4, and the second drawing of fig. 5, the amount-saving lotion pump is in an adjustment state, the stroke of the pump head 100 is the distance between the lower end of the adjustment sleeve 200 and the front of the cover 400, when the pump head 100 is pressed, the adjustment sleeve 200 will synchronously move downwards due to the relatively fixed distance between the adjustment sleeve 200 and the pump head until the adjustment sleeve is blocked by the cover 400 to stop moving downwards, so as to achieve the spraying of the lotion in the bottle. When the adjusting sleeve 200 moves upwards, the distance between the adjusting sleeve 200 and the pump head 100 is shortened, the pressing stroke of the pump head 100 is increased, and the maximum liquid spraying amount of the energy-saving emulsion pump is also increased; on the contrary, when the adjusting sleeve 200 moves downwards, the distance between the adjusting sleeve 200 and the pump head 100 increases, the stroke of the pump head 100 decreases, and the maximum liquid spraying amount of the saving lotion pump also decreases accordingly.
