[0025] As Figure 2 With Figure 3As shown, the inner side wall of the pressing pipe 5 is fixedly connected with a fixed ring 11, and the fixed ring 11 is arranged in correspondence with the size of the pressing pipe 5; the bottom of the fixed ring 11 is fixedly connected with a second reset spring 12, and the second reset spring 12 is arranged in correspondence with the size of the second glass bead 15; in work, the second reset spring 12 can limit the position of the second glass bead 15 by itself, and when the second glass bead 15 needs to be reset after each pressing of the nozzle 6 ends, the second reset spring 12 fixedly connected at the bottom of the fixed ring 11 can help the second glass bead 15 reset by the elastic force of itself; this step helps the second glass bead 15 reset by arranging the fixed ring 11 and the second reset spring 12, which is beneficial to speed up the reset process of the second glass bead 15, shorten the circulation time of the emulsion, thereby relieving the situation that the emulsion is still sprayed after the pressing ends, improving the emulsion output precision of the emulsion pump, and reducing waste.

[0026] As shown in Figure 3 , the bottom of the first reset spring 10 is fixedly connected with a limiting push block 14, and the limiting push block 14 is arranged in correspondence with the size of the liquid suction pipe 2; the surface of the limiting push block 14 is provided with a plurality of liquid leakage grooves arranged in a circular array; in work, when the first glass bead 13 needs to be reset, the limiting push block 14 fixedly connected at the bottom of the first reset spring 10 and arranged in correspondence with the size of the liquid suction pipe 2 can guide the first glass bead 13 to reset by itself, and in the process of the user pressing the nozzle 6, the emulsion can pass through the plurality of liquid leakage grooves provided on the surface of the limiting push block 14; this step arranges the limiting push block 14 and provides the liquid leakage grooves on the surface of the limiting push block 14 to guide the first glass bead 13, which is beneficial to solve the problem of the first glass bead 13 not resetting in time without affecting the emulsion outflow rate, so that the movement of the first glass bead 13 is more rapid, thereby improving the emulsion output precision of the emulsion pump.

[0027] As shown in Figure 2 and Figure 3 , the inner side wall of the sealing pipe 1 is fixedly connected with a limiting block 8, and the limiting block 8 is arranged in correspondence with the size of the movable pipe 7; in work, when the movable pipe 7 slides inside the sealing pipe 1, the limiting block 8 fixedly connected to the inner side wall of the sealing pipe 1 will be in contact and friction with the side wall of the movable pipe 7, and through the contact, the limiting block 8 can limit the movement posture of the movable pipe 7; this step limits the movement posture of the movable pipe 7 by fixedly connecting the limiting block 8 to the inner side wall of the sealing pipe 1, which is beneficial to avoid the deviation of the movable pipe 7 in the movement process, thereby improving the stability and durability of the emulsion pump, and prolonging the service life.

[0028] As shown in Figure 2 and Figure 3As shown, the side wall of the movable tube 7 is fixed with a stop bump 16, and a plurality of stop bumps 16 are arranged in a circumferential array; the top of the limiting block 8 is provided with a limiting groove, and the size of the limiting groove corresponds to the size of the stop bump 16; during work, when the movable tube 7 is moved to the preset limit position under the action of the user pressing force, the plurality of stop bumps 16 fixed on the side wall of the movable tube 7 will enter the limiting groove on the top of the limiting block 8, and contact and extrude the limiting groove, so that the movable tube 7 is forced to stop moving, wherein the limiting block 8 can also block the emulsion from entering the gap between the sealing tube 1 and the movable tube 7; this step limits the movement range of the movable tube 7 by setting the stop bump 16, avoids that the first glass bead 13 bears too much pressure, and thus protects the structure of the liquid suction tube 2, which is beneficial to avoid the damage of the liquid suction tube 2, improves the stability and durability of the emulsion pump, and is beneficial to prolong the service life of the emulsion pump.

[0029] As shown in Figure 3 , the inside of the nozzle 6 is provided with an emulsion outlet hole, and the emulsion outlet hole is arranged in an arc shape; during work, since the size of the emulsion outlet hole arranged in the inside of the nozzle 6 is smaller than the size of the through hole of the pressing tube 5, the emulsion will suffer greater pressure drop in the nozzle 6 during the emulsion outlet process, and since the emulsion outlet hole is arranged in an arc shape, the emulsion retained at the end of the emulsion outlet hole will slowly overflow under the action of gravity without being retained in the inside of the nozzle 6; this step avoids the emulsion from being retained in the inside of the nozzle 6 by arranging the emulsion outlet hole of the nozzle 6 in an arc shape, thereby avoiding the emulsion from being blocked after solidification, and improving the applicability and durability of the emulsion pump.

[0030] As shown in Figures 1 to 3 , the pressing tube 5 and the movable tube 7 are made of stainless steel; during work, the pressing tube 5 and the movable tube 7 made of stainless steel can take advantage of their own rust resistance and high strength, maintain the connection stability of the locking clamping teeth 17 and the locking clamping groove 18 for a long time, and thus maintain the anti-disassembly ability of the emulsion pump for a long time; this step improves the structural strength of the emulsion pump by using stainless steel for the pressing tube 5 and the movable tube 7, and thus maintains the function stability of the emulsion pump, which is beneficial to prolong the service life.
