Problems solved by technology
[0003] The purpose of the present invention is to provide an emulsion pump capable of sucking back the emulsion, which can effectively solve the problem that after the traditional emulsion is pumped out, the pump head retains the emulsion, which causes the emulsion to be easily polluted or touched by the outside world, and even drips easily when it is still. Falling, causing waste or getting wet and dirty bearing surface, polluting the environment and other issues

Embodiment Construction
[0026] A lotion pump capable of reabsorbing lotion according to the present invention is described in conjunction with the accompanying drawings.
[0027] Such as Figures 1 to 3 As shown, the lotion pump includes a pump head 1, a body 2 and a suction pipe 3 connected to each other. The body 1 is provided with an output tube 4, a piston 5 and an elastic limit mechanism 6. One end of the output tube 4 is connected to the pump head. 1, the other end is socketed with the piston 5, and moves up and down in the body 2 under the action of the elastic limit mechanism 6; the piston 5 is provided with a collar 51 that is socketed with the mouth of the output pipe 4; The output pipe 4 orifice is a convex pipe 41, and the diameter of the convex pipe 41 is less than the output pipe 4, so that the suction chamber 7 is formed between the outer edge of the convex pipe 4 and the inner wall of the collar 51; Or close the pipe valve 8 of the nozzle; when the output pipe 4 is pressed down by th...

The invention discloses a lotion pump capable of back-absorbing lotion, which comprises a pump head, a body and a suction pipe connected to each other. The body is provided with an output pipe, a piston and an elastic limiting mechanism. One end of the output pipe is connected to the pump head, and the other end is connected to the piston. Socketed, and under the action of the elastic limit mechanism, it moves up and down in the body; the piston is provided with a collar that is socketed with the nozzle of the output tube; the nozzle of the output tube is a convex tube, and the diameter of the convex tube is smaller than that of the output tube. A suction cavity is formed between the outer edge of the convex tube and the inner wall of the collar; it also includes a tube valve that cooperates with the piston to open or close the nozzle; when the output tube is pressed down by the pump head, the piston is pushed down to let the tube The valve opens the mouth of the outlet pipe; when the outlet pipe rises, the pipe valve closes the mouth of the outlet pipe and drives the piston back up to open the back-suction chamber to accommodate the back-suction emulsion. The emulsion pump of the present invention allows the emulsion remaining in the pump head to be sucked back and stored in the suction chamber, which solves the problem of waste or pollution caused by the residual emulsion in the pump head after the traditional emulsion is pumped out.
Description
technical field [0001] The invention relates to a lotion pump, in particular to a lotion pump capable of reabsorbing lotion. Background technique [0002] After the traditional lotion is pumped out, the pump head retains the lotion, and the lotion is easily polluted or touched by the outside world, and even drips easily when it is still, causing waste or getting wet and soiling the bearing surface. If the lotion pump is filled with oil and other For liquids, its defects are more obvious, so there are new problems for the improvement of lotion pumps. Contents of the invention [0003] The purpose of the present invention is to provide an emulsion pump capable of sucking back the emulsion, which can effectively solve the problem that after the traditional emulsion is pumped out, the pump head retains the emulsion, which causes the emulsion to be easily polluted or touched by the outside world, and even drips easily when it is still. Falling, causing waste or getting wet and...
