[0027] Example 1

[0028] Reference Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a quantitative extrusion device for skin medicine, which rotates the control knob 203 to rotate the control screw 301 in the extrusion barrel 100 to drive the displacement member 302 to extrude the preparation, so that the preparation is discharged from the extrusion barrel 100. When the control knob 203 is rotated, the limit member will contact and lock the release component 400 to complete the quantitative discharge of the preparation, improve the extrusion efficiency, and save the preparation.

[0029] Specifically, including:

[0030] An extrusion barrel 100; the interior of the extrusion barrel 100 is hollow;

[0031] The extrusion cover 200 is disposed at one end of the extrusion barrel 100; the extrusion cover 200 is provided with an extrusion port;

[0032] The control assembly 300 includes a control screw 301 disposed in the extrusion barrel 100, a displacement member 302 threadedly matched with the control screw 301 and slidably connected to the extrusion barrel 100, a control knob 303 disposed at an end of the control screw 301 away from the extrusion cover 200, and a stopper 304 disposed on the control knob 302;

[0033] The release assembly 400 is fixedly connected to the extrusion cylinder 100 and is located at an end of the control knob 303 away from the extrusion cover 200 ; the release assembly 400 cooperates with the limiting member 304 .

[0034] It should be noted that the skin medicine or cosmetic is located in the extrusion barrel 100, and the displacement member 302 is moved downward along the extrusion barrel 100 by rotating the screw 301, so that the preparation is extruded from the extrusion port. The end of the extrusion cover 200 is arc-shaped, and the corresponding displacement member 302 is adapted to the shape of the extrusion cover 200, and there is no dead angle.

[0035] Preferably, the extrusion cap 200 can be glued to the extrusion barrel 100 to facilitate the placement of the preparation into the extrusion barrel 100. Of course, the preparation can also be placed into the extrusion barrel 100 through one end of the control knob 303.

[0036] Preferably, the control screw 301 is rotatably connected to the extrusion barrel 100, wherein a slide groove can be provided on the inner wall of the extrusion barrel 100, and a slider adapted to the slide groove is provided on the displacement member 302. The rotation of the screw 301 drives the displacement member 302 to slide in the extrusion barrel 100.

[0037] Furthermore, the sealing cover 500 is detachably connected to the extrusion cover 101 .

[0038] Furthermore, the sealing cap 500 is provided with a sealing column 501 adapted to the extrusion port, which can block the extrusion port to achieve sealing.

[0039] Furthermore, the extrusion cover 101 is threadedly connected to the sealing cover 500 .

[0040] Furthermore, the limiting member 304 includes a mounting groove 304a opened on the end surface of the control knob 302, a limiting ball 304b arranged in the mounting groove 304a, and a spring 304c arranged in the mounting groove 304a and connected to the limiting ball 304b.

[0041] Furthermore, the release assembly 400 includes a support arm 401 connected to the extrusion cylinder 100 , a mounting plate 402 disposed on the support arm 401 , and a limiting hole 403 opened on the mounting plate 402 ; the limiting ball 304 b is adapted to the limiting hole 403 .

[0042] It should be noted that the limit member 304 is located at the edge of the end face of the control knob 302. When the control knob 302 is rotated, the limit ball 304b is driven to move. After rotating one circle, the limit ball 304b is lifted up by the spring 304c and positioned in the limit hole 403, thereby achieving quantitative extrusion of the preparation. At the same time, it can also prevent accidental touch from causing the control knob 302 to rotate and waste the preparation.

[0043] Preferably, a plurality of limiting members 304 can be provided according to actual conditions.

[0044] Preferably, because the release assembly 400 is connected to the extrusion barrel 100 , the release assembly 400 does not interfere with the rotation of the control knob 302 .

[0045] Furthermore, a mounting block 402a is provided on the mounting plate 402, and an extrusion rod 402b is hingedly provided on the mounting block 402a; a torque spring is provided between the extrusion rod 402b and the mounting block 402a; and the free end of the extrusion rod 402b corresponds to the position of the limiting hole 403.

[0046] It should be noted that, when the limiting ball 304b falls into the limiting hole 403, it is only necessary to press the extrusion rod 402b to compress the spring 304c, and the limiting ball 304b will be separated from the limiting hole 403, and at the same time, the control knob 302 is turned to realize the extrusion of the preparation, which is easy to operate.

[0047] Furthermore, the extrusion cylinder 100 is provided with an observation window, which can observe the remaining amount of the preparation in real time.

[0048] In summary, the utility model rotates the control knob 203 to rotate the control screw 301 in the extrusion barrel 100 to drive the displacement member 302 to extrude the preparation, so that the preparation is discharged from the extrusion barrel 100. When the control knob 203 is rotated, the limit member will contact and lock the release component 400 to complete the quantitative discharge of the preparation, improve the extrusion efficiency, and save the preparation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
