Detailed implementation mode

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer and more distinct, the present utility model will be further described in detail below in conjunction with the specific implementation modes and with reference to the attached drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0028] Detailed implementation mode one: As shown in Figure 1-7 A medicament smearing device includes: a machine base 1. A receiving cylinder 101 is provided inside the machine base 1. The receiving cylinder 101 is filled with medicament. A volume chamber 102 communicated with the receiving cylinder 101 is provided below the machine base 1. A roller 2 is provided inside the volume chamber 102. The initial position of the roller 2 is in contact with and closes the outlet of the volume chamber 102, and it can be displaced inwards by a certain distance when it is in contact with the skin and receives pressure. A gap outlet for the medicament to pass through is formed between the outer circle of the roller 2 and the inner wall of the volume chamber 102. During the rotation of the roller 2, the medicament is taken out of the inside of the volume chamber 102 to achieve the smearing operation; a housing 3, one end of the housing 3 is connected to the upper part of the machine base 1, and a pressure component 4 for pushing the medicament is provided inside. By applying a pushing pressure to the medicament in the receiving cylinder 101 through the pressure component 4, the medicament in the volume chamber 102 can be kept sufficient.

[0029] In a preferred embodiment, as shown in Figure 2 and Figure 4 Two installation grooves are provided on both sides of the volume chamber 102. The shape of the installation groove is a keyway shape. The end of the roller 2 is inserted into the installation groove to form a rotational connection and can slide along the installation groove. By installing a spring piece 201 in the installation groove, the spring piece 201 is in contact with the end of the roller 2. Under the action of the elastic force, the roller 2 is in close contact with the outlet of the volume chamber 102, and when it receives pressure, the roller 2 moves upwards against the elastic force of the spring piece 201 to achieve displacement and opening, and during the subsequent rolling process of the roller 2, the medicament smearing operation is completed.

[0030] In a preferred embodiment, as shown in Figure 2 , Figure 3 and Figure 5As shown in the figure, the pressure assembly 4 includes a threaded rod 5 and a mounting bracket 6; one end of the threaded rod 5 is connected to the upper rotating shaft of the sleeve 3 and is also connected to the driving motor at the upper end of the sleeve 3. A threaded hole is provided at the center above the mounting bracket 6, and the threaded hole is threadedly connected to the threaded rod 5. At the same time, two guide rods 601 that are symmetrically welded above the mounting bracket 6 and are slidably connected to the inner wall of the sleeve 3 are provided. The cross-section of the guide rod 601 is rectangular, and a pressure plate 602 is installed below the mounting bracket 6. The driving motor drives the threaded rod 5 to rotate, driving the mounting bracket 6 to displace along the axis of the threaded rod 5, so as to realize the pushing of the ointment inside the receiving cylinder 101 by the pressure plate 602; among them, the guide rod 601 plays a role of guiding and positioning, preventing the mounting bracket 6 from rotating circumferentially along with the threaded rod 5. At the same time, by arranging them in pairs, the stability during displacement can be improved.

[0031] In a preferred embodiment, in combination with Figure 7 As shown in the figure, vertically arranged slideways 301 are symmetrically provided on the inner wall of the sleeve 3, and the slideways 301 are in contact with the ends of the guide rods 601 to achieve sliding connection.

[0032] In a preferred embodiment, in combination with Figure 5 As shown in the figure, in order to facilitate the automatic flow of the ointment and automatically maintain the supply to a certain extent, two positioning columns 603 that penetrate the mounting bracket 6 are symmetrically provided on the pressure plate 602. A sliding connection is formed between the positioning columns 603 and the mounting bracket 6, and the springs 604 sleeved on the positioning columns 603 play a supporting role. During the displacement of the mounting bracket 6, the pressure plate 602 contacts the ointment, and as it continues to displace downward, overcoming the elastic force of the spring 604, a certain pre-pressure can be given to the ointment in the receiving cylinder 101. Thus, after the ointment in the volume cavity 102 decreases, automatic supply can be realized without frequently starting the driving motor to apply pressure.

[0033] In a preferred embodiment, in combination with Figure 3 and Figure 5 As shown in the figure, a cylindrical protrusion 605 is provided on the lower surface of the pressure plate 602, and the diameter of the cylindrical protrusion 605 is equal to the communication channel between the volume cavity 102 and the receiving cylinder 101, which can reduce the residue of the internal ointment.

[0034] In a preferred embodiment, in combination with Figure 3 、 Figure 5 and Figure 6As shown, a positioning block 606 is provided on the upper surface of the pressure plate 602. The positioning block 606 can be a polygonal structure such as a hexagon or a rectangle. A clamping groove 501 adapted to the positioning block 606 is provided at the lower end of the threaded rod 5. The top end of the slideway 301 is provided with an annular channel 302 on the inner wall of the housing 3 to provide a rotating space for the guide rod 601. Through the above structural design, the threaded rod 5 can be driven to rotate by the driving motor to drive the mixing member 607. Specifically, when the threaded rod 5 rotates in the reverse direction, the upper part of the mounting frame 6 is displaced to the topmost position and disengages from the threaded rod 5. Then, the positioning block 606 on the pressure plate 602 is pushed into the clamping groove 501, and axial positioning is achieved by the frictional force generated by the contact between the two. At this time, the guide rod 601 is exactly in the annular channel 302. Subsequently, the driving motor can drive the mixing member 607 to mix various ointments, effectively improving the overall usage scenario.

[0035] Preferred embodiments are combined with Figure 6 As shown, there is a circular sleeve above the mixing member 607. The circular sleeve is inserted into the cylindrical protrusion 605 to achieve installation positioning. In order to improve the connection stability between the two, a rubber layer can be added to the circular sleeve to increase the frictional force generated by the contact between the two. The cylindrical protrusion 605 is sleeved with the mixing member 607. There are two mixing rods below the mixing member 607, and the central distances of the two mixing rods from the center of the mixing member 607 are different, forming different mixing surfaces to improve the mixing effect. Specific embodiment two

[0037] For ease of installation operation, combined with Figure 2 As shown, the housing 3 and the machine base 1 are fixedly connected by insertion, and in order to prevent detachment, two connecting screws passing through the walls of both can be added to achieve axial fixation.

[0038] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
