Description

Technical Field

[0001] The present invention relates to the technical field of press pump heads, and in particular to a vacuum elastic press pump head. Background Art

[0002] Traditional pumps used in liquid or fluid daily chemicals, healthcare medicines, and cosmetics generally utilize the tension and rebound force of metal springs to achieve a pressing stroke, while also utilizing the spherical characteristics of glass beads, whose main component is silicon dioxide, to create a two-way valve.

[0003] In traditional pump bodies, other accessories except metal springs and glass beads are generally recyclable plastic parts. However, due to the presence of metal springs and glass beads, the entire pump body needs to be dismantled before recycling to remove the metal springs and glass beads. This will result in high recycling costs and waste of recyclable plastic parts, which is not environmentally friendly. In addition, dismantling the pump body requires a lot of manpower and material resources, resulting in a waste of resources. Summary of the Invention

DETAILED DESCRIPTION

[0024] See Figures 1-6 As shown, the technical solution adopted in this specific embodiment is: it includes a pump column 1, a main body 2, a buckle cover 4, an upper directional valve 7, a lower directional valve 8, a first sealing piston ring 9, and a second sealing piston ring 10. The upper directional valve 7 is installed below the inner cavity of the pump column 1, the pump column 1 is arranged in the inner cavity of the main body 2, the pump column 1 passes through its buckle cover 4, and the upper part of the main body 2 is snap-connected with the buckle cover 4, the upper part of the outer wall of the pump column 1 is sealed with the buckle cover 4 through the first sealing piston ring 9, the lower part of the outer wall of the pump column 1 is sealed with the main body 2 through the second sealing piston ring 10, and the lower directional valve 8 is installed below the inner cavity of the main body 2.

[0025] More specifically, a space is defined between the upper portion of the pump column 1, the upper portion of the inner cavity of the main body 2, and the lower portion of the buckle cover 4, and is sealed by a first sealing piston ring 9 and a second sealing piston ring 10, thereby forming a vacuum chamber A. The vacuum chamber A can maintain the original state of the pump column 1 and the main body 2 under atmospheric pressure.

[0026] More specifically, a pump volume chamber B is provided between the lower portion of the pump column 1 and the lower portion of the inner cavity of the main body 2. The pump volume chamber B is used for storing liquid.

[0027] More specifically, a push head 3 is provided on the top of the pump column 1. When the user needs to use the pump head, he only needs to press the push head 3, and the pump column 1 is pressed by the push head 3, wherein the liquid will also be discharged from the push head 3, which is convenient for the user to use.

[0028] More specifically, a locking cap 5 is provided at the outer end of the main body 2, and a gasket 6 is provided inside the locking cap 5. The locking cap 5 enables the device to be mounted on the bottle body, and the device is screwed onto the bottle body using the locking cap 5, while the gasket 6 added to the locking cap 5 prevents the liquid in the bottle from leaking.

[0029] More specifically, a straw 11 is installed below the main body 2. The liquid in the bottle is sucked through the straw 11, thereby extending the suction length of the main body 2.

[0030] More specifically, the inner cavity of the pump column 1 is provided with a pump column inner suction pipe 12. The pump column inner suction pipe 12 is used to guide the liquid in the pump column 1 to prevent the liquid from leaking sideways and to form a certain isolation from the outside air.

[0031] To be more specific, the pump column 1 is provided with a pump column connecting air channel 1-1 for facilitating the circulation of external gas and a piston ring groove 1-2 for installing the first sealing piston ring 9 and the second sealing piston ring 10. The bottom of the inner cavity of the pump column 1 is provided with a valve mounting hole 1-3 for installing the directional valve 7.

[0032] More specifically, a main body airway 2 - 1 for gas circulation and a valve placement groove 2 - 2 for placing the lower directional valve 8 are provided on the side of the main body 2 .

[0033] To be more specific, the upper directional valve 7 and the lower directional valve 8 are both butterfly-shaped plastic directional valves.

[0034] The working principle of the present invention is as follows: by utilizing the first sealing piston ring 9 and the second sealing piston ring 10, a closed vacuum chamber A is formed between the buckle cover 4, the main body 2 and the pump column 1. When the button 3 is pressed, the pump column 1 is pushed downward, thereby expanding the space of the vacuum chamber A, causing the pressure in the vacuum chamber A to drop sharply, and forming a certain pressure difference between the inside and outside of the vacuum chamber A. When the user releases the button 3, the vacuum chamber A will return to its original state under the pressure of the atmosphere, and then utilize the vacuum chamber A to make the pressing pump head have reciprocating ability. When the pump column 1 is pressed downward, the liquid in the pump volume chamber B will push the upper directional valve 7 upward, and will also squeeze the lower directional valve 8 downward, causing the side of the directional valve 8 to deform and seal the valve placement groove. 2-2, thereby effectively preventing the liquid in the pump volume chamber B from flowing back into the bottle body. At this time, the liquid will flow to the pressing head 3 through the suction pipe 12 in the pump column and be discharged from the pressing head 3. When the pump column 1 is under the retraction force of the vacuum chamber A, the sealing edge on the side of the upper directional valve 7 will deform and seal the valve mounting hole 1-3, so that the external gas will not enter the pump volume chamber B from the valve mounting hole 1-3, and the lower directional valve 8 will open, so that the liquid in the bottle body will be sucked into the pump volume chamber B through the suction pipe 11, which is convenient for the user to press and use next time. Among them, during the pressing operation, the gas in the pump column 1 and the main body 2 will be discharged and sucked in through the pump column connecting airway 1-1 and the main body airway 2-1, so that the internal air pressure is balanced with the external air pressure.

[0035] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
