When the pressure head 72 moves downward, the water filling piston 21 is kept fixed relative to the bottle body 1, and the water filling piston 21 moves upward relative to the pressure head 72 to press the liquid in the pressure head 72 into the water outlet 7a for discharging. When the pressure head 72 is restored upwards under the action of the pressure head spring 4, the water injection piston 21 moves downwards relative to the pressure head 72, and the inner body of the bottle body 1 is pumped into the water injection cavity 7b through the water inlet pipe 2, so that the skin-benefit liquid is smoothly discharged and extracted.

Referring to fig. 1 and 2, the water injection piston 21 includes an inner piston body 202 coaxially disposed and an outer piston sleeve 201 disposed outside the inner piston body 202, the outer piston sleeve 201 is coaxially and rotatably fitted with the inner piston body 202, a through hole 201b communicating with the water inlet pipe 2 is disposed in the center of the outer piston sleeve 201, the inner piston body 202 is provided with an air inlet passage 202a communicating with the air injection chamber 9, an air inlet check valve 202b is disposed in the air inlet passage 202a, the air inlet check valve 202b enables the air inlet passage 202a to be communicated with the water injection cavity 7b in a one-way manner, and the outer piston sleeve 201 is provided with an air inlet 201c corresponding to the air inlet passage 202 a. When the outer piston sleeve 201 rotates to a specific position, the air inlet 201c on the outer piston sleeve 201 is aligned with the air inlet channel 202a of the inner piston body 202, and the air inlet channel 202a is communicated with the air inlet 201 c; when the outer piston sleeve 201 rotates to other positions, the air inlet 201c and the air inlet channel 202a are dislocated, and the two are in a closed state. In order to ensure that the air in the air chamber 9 can be timely filled after the air injection piston 5 compresses and exhausts each time, a one-way valve can be arranged on the side wall of the air injection piston 5 or the air injection chamber 9 to form a one-way air inlet channel 202a, so that the outside air can only enter the air injection chamber 9 in one way.

As shown in fig. 2, 3 and 4, the inner wall of the water injection cavity 7b is provided with a slide groove 73 arranged along the vertical direction, the outer edge of the outer piston sleeve 201 is provided with a protrusion 201a slidably engaged with the slide groove 73, the upper end of the slide groove 73 is inclined to one side to form a chute section 73a, and when the outer piston sleeve 201 is located at the vertical section of the slide groove 73, the air inlet 201c and the air inlet channel 202a are kept in a normally closed state. When the pressure head 72 moves down to the bottom of the stroke, the outer piston sleeve 201 moves upward relative to the water injection cavity 7b, and when the outer piston sleeve 201 moves from the chute 73 to the chute section 73a, the chute section 73a drives the outer piston sleeve 201 to rotate relative to the inner piston body 202, so that the air inlet 201c is communicated with the air inlet channel 202 a.

As shown in fig. 5, the pressing member 3 is disposed at the bottom of the sleeve 71a, the pressing member 3 includes a base 32, the base 32 and the sleeve 71a are fixed, an air chamber 33 is disposed in the base 32, an outer sliding ring 3a and an inner sliding sleeve 5a acting on the air chamber 33 are disposed on the base 32, both the outer sliding ring 3a and the inner sliding sleeve 5a can slide relative to the base 32 along the axial direction of the sleeve 71a, and power is transmitted between the outer sliding ring 3a and the inner sliding sleeve 5a through the air chamber 33. As shown in fig. 6, when the ram 72 moves down to the bottom of the stroke, it contacts the outer sliding ring 3a, and when the outer sliding ring 3a moves down, the air chamber 33 moves the inner sliding sleeve 5a up to eject the gas injection piston 5 upward, so that the gas injection piston 5 injects gas into the water injection chamber 7 b. The outer sliding ring 3a comprises an upper ring 36 and a lower ring 35 which are coaxially arranged in parallel, the upper ring 36 is positioned above the base 32, the lower ring 35 is positioned in the air chamber 33, the upper ring 36 and the lower ring 35 are connected through a plurality of upright posts 31, an outer sliding ring spring 34 which acts on the upward movement of the lower ring 35 is arranged in the air chamber 33, the lower end of the pressure head 72 abuts against the upper ring 36 when the pressure head 72 moves downwards to the bottom, the lower ring 35 is pushed by the upright posts 31 to compress the outer sliding ring spring 34 and the air chamber 33, and when the external force on the pressure head 72 is removed, the outer sliding ring spring 34 rebounds to enable the outer sliding ring 3a to move upwards, so that the pressure head 72 is driven to move upwards. Because the pressure head 72 atress is great usually when the pressure head is pressed to the palm, consequently the pressure head 72 can drive outer slip ring 3a smoothly and compress outer slip ring spring 34, and outer slip ring spring 34 compression process can give the bigger reaction force of pressure head 72 simultaneously, promotes pressure head 72 and stops moving, avoids pressure head 72 excessively to move down and takes place the rigidity and strike direct transmission to the palm, is favorable to improving and uses the travelling comfort.

In actual use, as shown in fig. 1 and 5, the ram spring 4 is in an extended state, and the ram 72 is pushed up to the upper end of the stroke, and the water injection cavity 7b in the ram 72 is filled with liquid. When the pressing head 72 is pressed by the palm to move downwards, as shown in fig. 6, the water injection piston 21 is kept fixed relative to the bottle body 1, and the water injection piston 21 moves upwards relative to the pressing head 72, and since the water inlet pipe 2 is communicated to the water injection cavity 7b in a one-way manner, the liquid in the water injection cavity 7b can only be discharged through the water outlet 7 a. After the pressing head 72 moves down to contact with the upper ring 36 of the outer sliding ring 3a, the outer sliding ring 3a is pushed to further slide downwards, the air chamber 33 is compressed, the pressure in the air chamber 33 is increased, so that the inner sliding sleeve 5a is pushed to move upwards, the inner sliding sleeve 5a further pushes the air injection piston 5, and the air in the air injection chamber 9 is extruded into the water injection cavity 7 b. At this time, as shown in fig. 7, the ram 72 has reached the bottom of the displacement stroke, the ram spring 4 is in a compressed state, the volume of the water injection chamber 7b becomes minimum and close to zero, and air enters the water outlet 7a to discharge the liquid remaining in the water injection chamber 7b and the water outlet 7 a. When the pressure head 72 is released, the pressure head spring 4 pushes the pressure head 72 to return upwards, the pressure head 72 moves upwards to form negative pressure in the water injection cavity 7b, and the liquid in the bottle body 1 is pumped into the water injection cavity 7b through the water inlet pipe 2. At the same time, the outer sliding ring spring 34 pushes the outer sliding ring 3a to move upward, and negative pressure is generated in the air chamber 33, so that the inner sliding sleeve 5a and the gas injection piston 5 move downward, and the gas injection chamber 9 is filled with air. When the pressure head 72 is pressed down each time, a round of liquid discharging and exhausting actions can be performed, so that the skin benefiting liquid is prevented from remaining at the water outlet 7a and falling under the action of gravity. After the pressure head 72 is loosened, the liquid supplementing and air supplementing actions can be performed, and the preparation work is made for liquid discharging and air exhausting when the pressure head 72 is pressed down next time, so that the use convenience is improved.
