Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The emulsion pump beneficial to environmental protection of the utility model, as shown in figure 1, including the pump assembly 100, the pump assembly 100 has hard liquid suction pipe 6 used for inserting into bottle 99, the working principle of the pump assembly 100 belongs to the prior art, the emulsion pump of the utility model also includes soft liquid suction pipe 7 and standing suction head 8, the upper end of soft liquid suction pipe 7 is connected with lower end of hard liquid suction pipe 6; as shown in fig. 6, the vertical suction head 8 comprises a housing 81 and a balancing weight 82, the balancing weight 82 is arranged in the bottom of the housing 81, the housing 81 is formed with a spherical outer bottom 8101, that is, the outer wall of the bottom of the housing 81 is spherical, the lower end of the spherical outer bottom 8101 is provided with a suction head liquid outlet 802, the upper end of the housing 81 is provided with a suction head liquid outlet 802, and the lower end of the soft suction pipe 7 is connected with the suction head liquid outlet 802, in other words, the suction head liquid outlet 801 is connected with the hard suction pipe 6. As shown in fig. 7, the vertical suction head 8 is sunk on the bottle bottom 991 by gravity, so that when the pump assembly 100 is operated, negative pressure is generated at the liquid suction port 801, thereby sucking emulsion in the bottle body 99; because the balancing weight 82 is arranged in the bottom of the shell 81 and the outer wall of the bottom of the shell 81 is spherical, the standing suction head 8 forms a tumbler structure, so that the standing suction head 8 can be kept in a standing state, and the liquid suction port 801 can be kept to suck emulsion at the bottle bottom 991. When the emulsion in the bottle body 99 is nearly sucked up, and residual emulsion is left at the corner concave position of the bottle bottom 991, a user can incline the bottle body 99, the vertical suction head 8 slides down to the corner concave position of the bottle bottom 991 under the action of gravity, then the user vertically places the bottle body 99 again, and the spherical outer bottom 8101 slides relative to the bottle bottom 991 under the action of gravity of the balancing weight 82 due to the spherical outer wall of the bottom of the shell 81, so that the vertical suction head 8 is restored to the vertical state, and then the liquid suction port 801 can fully suck up the emulsion left in the corner concave position of the bottle bottom 991 as shown in fig. 7; or the user can maintain the bottle 99 in an inclined state for one to two minutes so that the residual emulsion is concentrated on one side, and since the standing suction head 8 is of a tumbler type structure, the pump assembly 100 can be operated to suck the residual emulsion intensively at the liquid suction port 801 while maintaining the inclination of the bottle 99. From the above, by arranging the emulsion pump of the present utility model, the waste caused by the large residual amount of emulsion is avoided, the bottle 99 and the emulsion pump are convenient to recycle, and the residual emulsion is prevented from being poured by personnel in a recycling station to pollute the environment, so the emulsion pump of the present utility model is favorable for saving and protecting the environment, and the emulsion pump of the present utility model also avoids the need of a user to invert the bottle 99 for a long time to pour the residual emulsion at the bottle bottom 991.

The flexible suction pipe 7 has flexibility, so the vertical suction head 8 can move flexibly; similar to the prior art, the hard liquid suction pipe 6 is arranged vertically, but because the soft liquid suction pipe 7 is arranged in the utility model, the lower end of the hard liquid suction pipe 6 does not need to be arranged against the bottle bottom 991, and by arranging the hard liquid suction pipe 6, the soft liquid suction pipe 7 is prevented from being knotted in the bottle body 99 in the transportation process due to the overlarge length of the soft liquid suction pipe 7. In order to avoid the edge of the liquid suction port 801 from forming a seal with the inner wall of the bottle bottom 991, as shown in fig. 6, for example, tooth grooves 8011 may be formed circumferentially at the edge of the liquid suction port 801 so that the emulsion can enter the liquid suction port 801 through the tooth grooves 8011. For example, in order to provide the hard pipette 6 with a certain hardness, the hard pipette 6 may be made of polypropylene, and in order to provide the soft pipette 7 with a good softness, the soft pipette 7 may be made of silicone rubber.

Further, as shown in fig. 6, the vertical suction head 8 includes an inner tube 83, a liquid through hole 8201 is formed in the counterweight 82, the lower portion of the inner tube 83 is disposed in the housing 81, the lower end of the inner tube 83 is connected to the upper end of the liquid through hole 8201, for example, a convex tube portion may be formed on the upper portion of the counterweight 82, the lower end of the inner tube 83 is tightly sleeved outside the convex tube portion, the lower end of the liquid through hole 8201 is connected to the liquid suction port 801 in an abutting connection manner, and the liquid suction head liquid outlet 802 is formed on the upper end of the inner tube 83.

Further, as shown in fig. 6, the casing 81 includes an upper casing 811 and a lower casing 812, the spherical outer bottom 8101 is formed on the lower casing 812, the upper end of the inner tube 83 protrudes from the top of the upper casing 811, the lower end of the flexible pipette 7 can be tightly sleeved outside the upper end of the inner tube 83, the lower end of the upper casing 811 is adapted to be connected outside the upper end of the lower casing 812, in order to make the casing 81 have a better fall-preventing performance, the casing 81 is configured to have an egg-shaped outer shape structure with a small upper part and a large lower part, and the weight 82 is conveniently placed into the casing 81 by adopting the casing 81 as a combined structure of the upper casing 811 and the lower casing 812. The upper shell 811 and the lower shell 812 may be bonded.

Further, the counterweight 82 is made of stainless steel, the counterweight 82 is adhered to the inner wall of the lower shell 812, rust of the counterweight 82 is avoided, and the fall-preventing effect of the vertical suction head 8 is improved.

Further, as shown in fig. 1 and 5, the emulsion pump of the present utility model further comprises a connection cover 9, wherein the upper part of the connection cover 9 is adhered to the lower end of the hard liquid suction pipe 6, specifically, the upper part of the connection cover 9 is sleeved outside the lower end of the hard liquid suction pipe 6, the lower part of the connection cover 9 is formed with a lower convex pipe joint 91, and the upper end of the soft liquid suction pipe 7 is sleeved outside the lower convex pipe joint 91, so that the hard liquid suction pipe 6 and the soft liquid suction pipe 7 are conveniently connected, and the parts of the pump assembly 100 can be manufactured by adopting the original mold, only the length of the hard liquid suction pipe 6 and the lower end structure of the hard liquid suction pipe 6 are changed, which is beneficial for emulsion pump manufacturers to improve the emulsion pump products at low cost and rapidly.
