[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1-3 The utility model provides a technical solution: a pump head structure of a lotion pump, including a containing body 1, an integration part 2 is provided inside the containing body 1, the top end of the integration part 2 is pulled out and extended to the outside of the containing body 1, and a pressing head 9 is provided, and a discharge port 10 is provided on the surface of the pressing head 9. The pressing head 9 and the discharge port 10 are integrally formed, and the discharge port 10 extends to the outside of the pressing head 9, and can be formed into different shapes and specifications according to production requirements.

[0020] The integration part 2 is composed of a main column position part 14, a piston position 13 and a secondary column position part 15 arranged vertically. The upper part of the inner cavity of the main column position part 14 is provided with an upper sealing position 8, and the upper part of the inner cavity of the main column position part 14 is provided with an upper glass bead 7 adapted to the upper sealing position 8.

[0021] A liquid inlet channel 16 communicating with the inner cavity of the main column position 14 is provided on the surface of the auxiliary column position 15. A boss position 3 is provided at the lower part of the inner cavity of the accommodating body 1. A spring 4 is vertically fixedly connected between the bottom of the piston position 13 and the bottom of the inner wall of the boss position 3.

[0022] Through the integrated part 2 composed of the main column position part 14, the piston position 13 and the auxiliary column position part 15, three accessories with different functions are integrated together through one-time forming technology, which reduces production costs, simplifies the production and assembly processes, and improves production efficiency. At the same time, one-time forming reduces the occupancy of machines and molds, reduces mold costs, and improves production efficiency. The simplification of the assembly process not only reduces assembly time and cost, but also improves the quality of accessories and enhances product stability and reliability.

[0023] When the lotion pump head is in the locked state, the piston portion 13 of the integration part 2 contacts the spring 4 and abuts against the upper portion of the boss portion 3 to form a seal, thereby performing a sealing function.

[0024] When the lotion pump head is pressed up and down, the piston position 13 of the integration part 2 slides and seals with the inner wall of the containing body 1, and the upper sealing position 8 of the integration part 2 cooperates with the upper glass bead 7 to generate suction and seal.

[0025] A connecting cover 6 is fixedly connected to the upper part of the side wall of the accommodating body 1, and an internal thread 12 is provided on the inner wall surface of the connecting cover 6. A lower glass bead 5 is provided at the bottom of the inner cavity of the accommodating body 1, and a lower sealing position 11 adapted to the lower glass bead 5 is provided at the bottom of the inner cavity of the accommodating body 1.

[0026] Tighten the connecting cap 6 onto the mouth of the bottle filled with contents, rotate the push head to open the lotion pump, and press the push head 9 downward. The space inside the container body 1 shrinks from large to small. Since the lower sealing position 11 is now sealed with the lower glass bead 5 of the container body 1, and the seal between the upper glass bead 7 and the upper glass bead 7 of the integration part 2 is opened, the air in the cavity of the container body 1 is forced into the integration part 2 through the channels on both sides of the liquid inlet channel 16 of the integration part 2, and then discharged from the top of the main column part 14 of the integration part 2 through the push head 9 and the inside of the discharge port 10.

[0027] The bottom end of the containing body 1 is connected to a straw. When the pressing head 9 is released, the integrating part 2 is lifted up by the natural rebound action of the spring 4, contacts the inner wall of the containing body 1 and slides upward. At this time, the space inside the containing body 1 changes from small to large, and the piston position 13 of the integrating part 2 is sealed with the inner wall of the containing body 1. The upper glass bead 7 is sealed with the upper sealing position 8 of the integrating part 2, blocking the air inside and outside the containing body 1. A pre-pressure is generated in the containing body 1 to form a vacuum. The vacuum negative pressure opens the sealing point between the lower glass bead 5 and the lower sealing position 11 of the containing body 1, and sucks in the air in the straw and the contents of the bottle.

[0028] By repeating the pressing process, the air in the container body 1 can be completely exhausted, and the contents in the bottle can be stored to fill the quantitative space in the container body 1.

[0029] When the quantitative space in the container body 1 is filled with contents, the pressing head 9 is pressed again. Due to the squeezing, the contents are forced to pass through the liquid inlet channel 16 of the integration part 2, through the interior of the integration part 2 to the top of the main column part 14, and then discharged through the interior of the discharge port 10.

[0030] Furthermore, a sealing ring 17 adapted to the pressing head 9 is fixedly connected to the top end of the surface of the integration member 2 , and the sealing ring 17 improves the sealing between the integration member 2 and the pressing head 9 .

[0031] Furthermore, a protective shell 18 is fixedly connected to the top of the housing body 1, and anti-slip grooves are provided on the top of the pressing head 9.

[0032] The working principle and use process of the present invention: After the present invention is installed, the connecting cover 6 is tightened to the bottle mouth filled with the contents, the pressing head is rotated to open the lotion pump, and the pressing head 9 is pressed downward. The space inside the containing body 1 changes from large to small. Since the lower sealing position 11 is sealed with the lower glass bead 5 of the containing body 1, and the sealing position of the upper glass bead 7 and the upper glass bead 7 of the integration part 2 is opened, the air in the cavity of the containing body 1 is forced to enter the inside of the integration part 2 from the channels on both sides of the liquid inlet channel 16 of the integration part 2, and then discharged from the top of the main column part 14 of the integration part 2 through the pressing head 9 and the inside of the liquid discharge port 10. When the pressing head 9 is released, the integration part 2 is lifted up under the natural rebound action of the spring 4, contacts the inner wall of the containing body 1 and slides upward. At this time, the containing body 1 The inner space is enlarged, the piston position 13 of the integration part 2 is sealed with the inner wall of the containing body 1, and the upper glass bead 7 is sealed with the upper sealing position 8 of the integration part 2, blocking the air inside and outside the containing body 1. A pre-pressure is generated in the containing body 1 to form a vacuum. The vacuum negative pressure opens the sealing point between the lower glass bead 5 and the lower sealing position 11 of the containing body 1, and sucks in the air in the straw and the contents in the bottle. The pressing process is repeated to completely discharge the air in the containing body 1 and store the contents in the bottle to fill the quantitative space in the containing body 1. When the quantitative space in the containing body 1 is filled with the contents, the pressing head 9 is pressed again. Due to the squeezing of the contents, the contents are forced to pass through the liquid inlet channel 16 of the integration part 2, through the interior of the integration part 2 to the top of the main column part 14, and then discharged through the interior of the drain port 10.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
