[0018] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0019] See also Figure 1-5The utility model provides an embodiment: a skin roller needle capable of automatically administering medication, comprising a shell 3, a roller needle rack 6 with one end sliding inside the shell 3, and a liquid outlet 11 arranged on the roller needle rack 6; a connecting piece 1 is provided at the bottom of the shell 3, and a sliding piece 8 is provided between the connecting piece 1 and the roller needle rack 6; a protrusion 4 is provided on the sliding piece 8, and a recessed portion 5 is provided on a side of the roller needle rack 6 facing the protrusion 4; the roller needle rack 6 is moved toward the connecting piece 1 to insert the protrusion 4 into the recessed portion 5, so as to squeeze the liquid through the liquid outlet 11 to flow toward the roller needle.

[0020] To sum up, after the bottle of essence or the like is connected to the connecting piece 1, the device is inverted, and the liquid flows to the recessed portion 5 through the sliding piece 8; when the device rolls on the skin, the device can be pressed downward to cause the roller frame 6 to move toward the connecting piece 1, thereby causing the protruding portion 4 to move toward the recessed portion 5 to squeeze the liquid entering the recessed portion 5, and then use external force to cause the liquid to flow outward, so as to overcome the problem that the viscous liquid cannot flow out automatically.

[0021] Furthermore, since the sliding member 8 guides the liquid to flow toward the recessed portion 5 through the liquid inlet hole 10, the liquid can flow directly to the recessed portion 5, thereby reducing the waste of liquid caused by the liquid flowing in all directions and causing a large amount of liquid to remain inside the device. The sliding member 8 is made of rubber material, and a baffle is provided at one end away from the protruding portion 4, so that the baffle covers the hole on the connecting member 1, so as to guide the liquid to flow only along the inside of the sliding member 8 to the recessed portion 5.

[0022] Furthermore, since the outside of the sliding member 8 is also provided with a separating member 7 for causing the protrusion 4 to separate from the recessed portion 5, when the external force disappears, the separating member 7 can cause the protrusion 4 to separate from the recessed portion 5, and at this time, the liquid can be replenished again. When the user presses again, the liquid can flow out again; thereby, the device can repeatedly and continuously replenish the medicine; wherein, the separating member 7 is preferably a spring, and after the separating member 7 is sleeved on the outside of the needle roller frame 6, one end of the separating member 7 abuts against the needle roller frame 6, and the other end abuts against the sliding member 8.

[0023] On the basis of the above scheme, in order to solve the problem in the prior art that the liquid cannot be evenly applied to the skin due to the number of liquid outlet holes, the number of the liquid outlet holes 11 is multiple, and the multiple liquid outlet holes 11 are arranged side by side on the needle roller frame 6; because the liquid outlet holes 11 are arranged horizontally in a row on the needle roller frame 6, the dripping droplets are evenly dripped into the entire area of ​​the roller, so that the essence can be evenly spread on the skin surface and evenly introduced into the skin.

[0024] Furthermore, since a guide portion 12 is provided on the outer wall surface of the needle roller frame 6, and the guide portion 12 is slidably matched with a guide groove 13 provided in the shell 3, the guide portion 12 can be used to slide inside the guide groove 13 to avoid axial rotation of the needle roller frame 6, thereby ensuring that the path of each rolling of the needles on the needle roller frame 6 is effectively controlled and guaranteed, thereby further ensuring that the liquid can be spread on the skin surface and evenly introduced into the skin.

[0025] In addition, after the connecting member 1 is connected to the shell 3, it is connected to the connecting member 1 through the fastener 2 provided on the outside of the shell 3 to fix the connecting member 1 to the bottom of the shell 3, thereby making the connection between the connecting member 1 and the shell 3 stable and reliable. Specifically, the bottom of the shell 3 is inserted into the annular groove provided on the inner wall of the connecting member 1 through the protruding annular boss, and then the fastener 2 is used to thread downward with the connecting member 1 from the outside of the shell 3 or to snap-fit ​​so as to reliably fix the connecting member 1 to the bottom of the shell 3; wherein, the connection method between the connecting member 1 and the shell 3 can also refer to the prior art.

[0026] Furthermore, since a protective cover 9 is provided on the outside of the housing 3 , when the protective cover 9 covers the outside of the needle roller frame 6 , the needle rollers on the needle roller frame 6 can be protected.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
