Refer to
A ladder-shaped valve spool 41 is arranged at a lateral part of the down-pressure valve 4, and a liner 32 of the press head which may be clamped into the ladder-shaped valve spool 41 is arranged in the rotary press head 3.
Further, a shoulder sleeve 5 with scale lines is arranged on an outer part of the massage head 2, and inner convex ribs 51 corresponding to the scale lines are arranged in the shoulder sleeve 5.
Further, an indicator strip 21 is arranged on the outer part of the massage head 2, and outer convex ribs 23 are arranged below the indicator strip 21.
According to the technical solution, the massage head 2 is provided with the scale lines having an indication function, and the indicator strip 21 indicates different scale lines. This is convenient for users to adjust and use. In addition, the outer convex ribs 23 on the outer part of the massage head 2 are matched with the inner convex ribs 51 corresponding to squirting scales in the shoulder sleeve, and there is obvious hand feeling and a sound prompt at each scale, so that a user may conveniently grasp a quantity of liquid output.
Further, a first connection buckle 22 is arranged in the massage head 2, a first connection groove 31 is arranged an outer part of the rotary press head 3, and the first connection buckle 22 is clamped with the first connection groove 31.
According to the technical solution, due to a connection structure of the massage head 2 and the rotary press head 3, when the press head 3 is rotated, the press head may be synchronously rotated with the massage head 2. Therefore, the rotary press head 3 may be rotated by rotating the massage head 2.
Further, a plurality of groups of ladder-shaped structures are arranged on the ladder-shaped valve spool 41.
Further, a limiting strip 42 is arranged on outside a bottom of the down-pressure valve 4, and a vertically-arranged limiting groove 61 is arranged in the connection sleeve 6.
According to the technical solution, when the rotary press head 3 is rotated, the liner 32 of the press head moves on the ladder-shaped valve spool 41. Because limiting groove 61 limits a movement direction of the limiting strip 42, the down-pressure valve 4 may not be rotated with the rotary press head 3, and may only be pressed down. Due to the ladder-shaped structure of the ladder-shaped valve spool 41, rotation amplitudes of the rotary press head 3 are different, and down-pressing heights of the down-pressure valve 4 are also different. This may control different down-pressing heights by controlling a height of each step of the ladder-stepped structure, to squeeze out doses of cosmetics or skin care products. In addition, a plurality of liquid output indicators may be provided by setting different groups of steps. Therefore, in actual use, the ladder-shaped valve spool 41 may be specially designed according to use requirements.
Further, there are two groups of pump bodies 9, the two groups of pump bodies 9 are respectively installed on an upper side and a lower side of the down-pressure valve 4, and a liquid storage chamber is arranged a top opening of the down-pressure valve 4.
According to the technical solution, the rotary press head 3 may be rotated, by rotating the massage head 2 clockwise, following the rotation of the massage head 2, therefore the liner 32 of the press head moves on the ladder-shaped structure of the ladder-shaped valve spool 41. The down-pressure valve 4 moves downward to drive the lower pump bodies 9 to move downward, so as to open pistons in pump cores. In this case, liquid enters the liquid storage chamber at the top of the down-pressure valve 4 via a center hole of the valve from a valve needle hole. When the down-pressure valve 4 moves downward, pistons in the upper pump bodies 9 do not move, space of the liquid storage chamber at the top of the down-pressure valve 4 is enlarged, and a specific quantity of liquid is stored in the liquid storage chamber. In this case, the massage head 2 is rotated counterclockwise to “0”, the liner 32 of the press head moves down along the ladder-shaped structure of the ladder-shaped valve spool 41, and the down-pressure valve 4 rises to close the pistons in the pump cores of the lower pump bodies 9 to close. As the down-pressure valve 4 rises, the space of the liquid storage chamber at the top is compressed, and liquid is pumped out from a hole at the tops of the pistons of the upper pump bodies 9, to squeeze out the specific quantity of liquid.
Further, a top end of the connection tube 8 is connected with the massage head 2 in an interference fitting and sealing manner, and a bottom end of the connection tube 8 is connected with the down-pressure valve 4 in the interference fitting and sealing manner.
Further, a valve plate 7 is arranged in an inner hole of the massage head 2, a flexible plate is arranged on the valve plate 7, and an upper cover 1 is arranged above the massage head 2.
According to the technical solution, a buckling position of the valve plate 7 is matched with an inner hole at the top of the massage head 2, and an liquid outlet may be sealed after assembly. When liquid is squeezed out, the flexible plate at the top of the valve plate 7 is punched out, and liquid is squeezed out from the periphery of the valve plate 7.
Further, the bottom of the massage head 2 abuts against the connection sleeve 6.
According to the technical solution, the massage head 2 may only be rotated but may not be pressed down under limitation of the connection sleeve 6.
Operating principles are: The rotary press head 3 may be rotated, by rotating the massage head 2 clockwise, following the rotation of the massage head 2, therefore the liner 32 of the press head moves on the ladder-shaped structure of the ladder-shaped valve spool 41. The down-pressure valve 4 moves downward to drive the lower pump bodies 9 to move downward, so as to open pistons in pump cores. In this case, liquid enters the liquid storage chamber at the top of the down-pressure valve 4 via a center hole of the valve from a valve needle hole. When the down-pressure valve 4 moves downward, pistons in the upper pump bodies 9 do not move, space of the liquid storage chamber at the top of the down-pressure valve 4 is enlarged, and a specific quantity of liquid is stored in the liquid storage chamber. In this case, the massage head 2 is rotated counterclockwise to “0”, the liner 32 of the press head moves down along the ladder-shaped structure of the ladder-shaped valve spool 41, and the down-pressure valve 4 rises to close the pistons in the pump cores of the lower pump bodies 9 to close. As the down-pressure valve 4 rises, the space of the liquid storage chamber at the top is compressed, and liquid is pumped out from a hole at the tops of the pistons of the upper pump bodies 9, to squeeze out the specific quantity of liquid.
Finally, it should be noted that the foregoing embodiments are merely intended for describing the technical solutions of the present invention, instead of limiting the present invention.
