[0028] An acne cleaning device for dermatology, as Figures 1-5As shown in the figure, it includes a housing 1 and an ointment application frame 2. The housing 1 is the assembly carrier of this cleaning device. The housing 1 is a square housing that is open top and bottom. At the bottom opening of the housing 1, an ointment application frame 2 is fixedly installed. The ointment application frame 2 is provided with micro through grooves and has uneven textures on its surface. The ointment application frame 2 is used to apply evenly on the skin the ointment for treating acne. It also includes: a fixing plate 3, fixedly installed on the inner wall of the housing 1; a sliding frame 4, installed on the bottom surface of the fixing plate 3 through a damper 41; an operation plate 5, a guiding groove 51 is opened on the front surface of the housing 1, and the operation plate 5 is slidably installed in the guiding groove 51 of the housing 1. The operation plate 5 is connected to the sliding frame 4; mounting plates 6, there are two of them and they are symmetrically fixedly connected to both sides of the bottom of the sliding frame 4. Between the two mounting plates 6, there is a cleaning component 7 for cleaning acne. The cleaning component 7 includes a cleaning roller 71, a guiding cylinder 72, an air-filled bag 73, a mounting block 74, a thorn needle 75 and a needle driving member. The cleaning roller 71 is rotatably installed between the two mounting plates 6. The cleaning roller 71 is a hollow roller made of medical nitrile rubber. Inside the cleaning roller 71, a guiding cylinder 72 is fixedly installed. In the chamber of the cleaning roller 71 where the guiding cylinder 72 is located, an air-filled bag 73 is fixedly installed. A plurality of groups of mounting blocks 74 are circumferentially and spacedly fixed on the outer surface of the air-filled bag 73. A plurality of thorn needles 75 are spacedly fixedly installed on each mounting block 74. The thorn needles 75 are densely distributed on the corresponding mounting blocks 74. The needle bodies of the thorn needles 75 slidably penetrate through the guiding cylinder 72. The cleaning roller 71 is densely provided with needle holes corresponding to the thorn needles 75. The needle tips of the thorn needles 75 are located in the barrel needle holes of the cleaning roller 71. Inside the housing 1, there is a needle driving member for driving the thorn needles 75 to perform telescopic movement on the cleaning roller 71. When the cleaning roller 71 rolls over the acne skin, the needle driving member is used to drive the needle tips of the multiple groups of thorn needles 75 inside the cleaning roller 71 to slightly extend out, and as the cleaning roller 71 rolls, it synchronously pierces the acne on the skin. In cooperation with the ointment application frame 2, the bactericidal and anti-inflammatory ointment is timely applied to the wound of the acne, preventing infection after acne cleaning and treating the inflammation, and improving the efficiency and effect of acne cleaning.

[0029] As Figures 3-5As shown, the needle driving member includes a drum airbag 8, a mounting seat 81, and an air delivery pipe 82. The mounting seat 81 is fixedly provided on the inner wall of the housing 1 on the side away from the operation board 5. The drum airbag 8 is assembled on the mounting seat 81. The drum airbag 8 is communicated to both sides of the inflation airbag 73 through the air delivery pipes 82 on both sides. A pressing plate 42 is fixedly installed on the upper part of the sliding frame 4. The pressing plate 42 is located directly above the drum airbag 8. After cleaning the skin of the acne, the user holds the housing 1 and presses the medicine application frame 2 tightly against the skin of the acne, and moves the device on the skin of the acne. While the medicine application frame 2 passes through the acne position on the skin, by pushing the operation board 5 towards the skin, the operation board 5 drives the mounting plate 6 and the cleaning roller 71 to move towards the skin after overcoming the resistance of the damper 41 until the cleaning roller 71 fits on the skin. When the sliding frame 4 moves down to the maximum stroke, the pressing plate 42 will press on the drum airbag 8, causing the drum airbag 8 to fill the inflation airbag 73 with gas through the air delivery pipe 82, causing the inflation airbag 73 to expand and drive the acupuncture needle 75 to expand outwards through the mounting block 74, so that the needle tip of the acupuncture needle 75 extends from the surface of the cleaning roller 71, so as to perform the operation of puncturing and cleaning the acne on the skin.

[0030] As Figure 2 , Figure 6 and Figure 7 shown, a medicine storage box 9 is fixedly assembled on the inner wall of the top of the housing 1. The medicine storage box 9 is used to store medicines such as anti-inflammatory ointments used for acne cleaning. The four corners of the bottom of the medicine storage box 9 are communicated to the medicine application frame 2 at the bottom of the housing 1 through medicine delivery pipes 91. An inflation member 10 is provided at the position of the housing 1 where the medicine storage box 9 is located. The inflation member 10 is used to inflate the medicine storage box 9 and automatically press the ointment into the medicine application frame 2 through air pressure, thus saving the operation of manually applying medicine on the medicine application frame 2.

[0031] As Figure 1 , Figure 6 and Figure 7 shown, the inflation member 10 includes a piston block 101, a sliding block 102, a first spring 103, and a one-way valve 104. The piston block 101 is slidably installed on the inner wall of the top opening of the housing 1 through the sliding blocks 102 on both sides. A first spring 103 is provided between the sliding block 102 and the housing 1. The top of the medicine storage box 9 is open. The piston block 101 and the medicine storage box 9 are in sealed and sliding fit. A one-way valve 104 is assembled on the piston block 101. The one-way valve 104 conducts the medicine storage box 9 unidirectionally for the piston block 101. By pressing the piston block 101 against the elastic force of the first spring 103, the piston block 101 will move towards the medicine storage box 9 under the guidance of the sliding block 102 and compress the air pressure in the box. Since the air pressure inside the medicine storage box 9 cannot be discharged outward through the one-way valve 104, as the air pressure in the medicine storage box 9 increases, under the action of the air pressure, the ointment inside the medicine storage box 9 can flow through the medicine delivery pipe 91 and then flow into the medicine application frame 2, facilitating the subsequent medicine application operation.

[0032] Before using this acne cleaning device, the user needs to first add a certain amount of bactericidal and anti-inflammatory ointment into the medicine storage box 9. When cleaning and treating acne, press the piston block 101 on the top of the housing 1 with hand. The piston block 101 moves downward under the guidance of the sliding block 102, overcoming the elastic force of the first spring 103, compressing the air inside the medicine storage box 9. Since a one-way valve 104 is provided at the opening at the top of the medicine storage box 9, the one-way valve 104 only allows air to flow into the medicine storage box 9 and cannot be discharged. After the air pressure inside the medicine storage box 9 increases, the ointment uniformly flows into the micro-channels of the medicine application frame 2 under the drive of the air pressure and adheres to the concave-convex textures on its surface. After releasing the piston block 101, the piston block 101 rebounds and resets under the action of the first spring 103, and the air is replenished into the medicine storage box 9 through the one-way valve 104. Subsequently, the user holds the housing 1 with one hand, fits the bottom surface of the medicine application frame 2 to the acne skin area and smoothly moves it along the skin surface. The concave-convex texture design of the medicine application frame 2 can promote the uniform diffusion of the ointment through physical friction. At the same time, the micro-channels ensure that the ointment continuously oozes out and forms a thin layer covering the skin surface. When the device moves to the acne bump area, the user needs to apply a little pressure and push the operation board 5 towards the skin direction with the thumb. The operation board 5 slides along the housing 1 in the guiding groove 51 and drives the sliding frame 4 to move against the resistance of the damper 41, so that the mounting plate 6 and the cleaning roller 71 fixedly connected to the bottom of the sliding frame 4 can smoothly move towards the skin until the cleaning roller 71 fits onto the skin. When the sliding frame 4 moves down to the maximum stroke, the pressing plate 42 on the sliding frame 4 just tightly presses the surface of the air bag 8. After the air bag 8 is squeezed by the pressing plate 42, the gas inside the air bag 8 is injected into the inflatable bag 73 inside the cleaning roller 71 at high speed through the two side air pipes 82. After the inflatable bag 73 is inflated, it pushes the circumferentially distributed mounting blocks 74 to expand outwards. Multiple needles 75 on the mounting blocks 74 accurately extend outwards along the needle holes under the limitation of the guiding cylinder 72. At this time, during the rolling process of the cleaning roller 71 when the user pushes the device, the needle tips of the needles 75 slightly pierce into the epidermis of the acne pustule, destroying the pustule structure through mechanical puncture, releasing the internal pus, and at the same time avoiding excessive penetration and damage to the deep tissues. While puncturing the acne, the moving medicine application frame 2 has synchronously covered the pre-applied ointment to the wound. The antibacterial components in the ointment directly act on the exposed wound surface, realizing a synchronous closed-loop operation of debridement and treatment, and greatly reducing the infection risk.

[0033] As Figure 6 and Figure 8As shown, a scraping block 11 is slidably installed at the bottom of the sliding frame 4 through a guide rod 12. The bottom surface of the scraping block 11 is an arc surface adapted to clean the surface of the cleaning roller 71. A second spring 13 is provided between the sliding frame 4 and the guide rod 12. The scraping block 11 is closely attached to the surface of the cleaning roller 71 under the elastic force of the second spring 13. When the cleaning roller 71 rotates in the housing 1 to clean acne, a mixed waste liquid of part of the ointment and acne pus will adhere to the surface of the cleaning roller 71. When the mixed waste liquid on the surface of the cleaning roller 71 passes through the scraping block 11, it will be scraped out by the scraping block 11 and is convenient for subsequent cleaning and collection.

[0034] As Figure 8 shown, an installation groove is provided on the side surface of the housing 1 facing away from the operation panel 5. A waste liquid box 14 is slidably assembled in the installation groove of the housing 1. A liquid suction pipe 15 is fixedly installed on the side surface of the waste liquid box 14 close to the cleaning roller 71 through a support plate 151. A liquid suction port is provided on one side wall of the liquid suction pipe 15. The liquid suction port of the liquid suction pipe 15 faces and is close to the joint of the cleaning roller 71 and the scraping block 11. A liquid extraction pump 16 is installed at the inner bottom of the waste liquid box 14. The inlet of the liquid extraction pump 16 is communicated with the liquid suction pipe 15 through a connecting pipe 17. By the operation of the liquid extraction pump 16 in the waste liquid box 14, a negative pressure is formed in the liquid suction pipe 15 through the connecting pipe 17 by the liquid extraction pump 16, so that the liquid suction pipe 15 can suck the waste liquid scraped out by the scraping block 11 through the liquid suction port, and the sucked waste liquid will be transported to the waste liquid box 14 for centralized collection and subsequent treatment.

[0035] As Figure 8 shown, a convex rod 141 is fixedly provided on the outer box body of the waste liquid box 14. Two buckle plates 18 are symmetrically hinged up and down at the installation groove of the housing 1 where the waste liquid box 14 is assembled. A clamping groove adapted to the convex rod 141 is provided on the buckle plate 18. When the waste liquid box 14 is assembled onto the housing 1, by rotating the buckle plate 18, the clamping groove on the buckle plate 18 can be buckled onto the corresponding convex rod 141 of the waste liquid box 14, so that the waste liquid box 14 can be conveniently disassembled and assembled on the housing 1.

[0036] As Figure 5 and Figure 9As shown, it also includes an extrusion block 19. An extrusion block 19 is fixedly installed in each needle hole of the cleaning drum 71. The extrusion block 19 is made of elastic material. The interior of the extrusion block 19 is a conical through hole adapted to the needle head of the thorn needle 75. The needle head of the thorn needle 75 penetrates into the extrusion block 19. The extrusion block 19 fits tightly on the needle head of the thorn needle 75. When the thorn needle 75 pierces to the outside of the cleaning drum 71, the extrusion block 19 will elastically stretch open. When the thorn needle 75 retracts into the cleaning drum 71, the extrusion block 19 will press the acne waste liquid remaining at the needle head of the thorn needle 75 outward, so that the acne waste liquid at the needle head of the thorn needle 75 after the thorn needle 75 is retracted is blocked by the extrusion block 19 at the needle hole on the surface of the cleaning drum 71, so as to prevent the acne waste liquid from polluting the inside of the cleaning drum 71 and facilitate the subsequent cleaning of the waste liquid on the surface of the cleaning drum 71.

[0037] After completing the acne puncture operation, the user resets and pushes back the operating panel 5, and the operating panel 5 drives the sliding frame 4 and the cleaning roller 71 to move up and out of contact with the skin, and the pressure plate 42 of the sliding frame 4 separates from the air bag 8. At this time, the air bag 8 rebounds to its original state due to the pressure release, and the gas in the air bag 73 flows back into the air bag 8 through the air pipe 82. The air bag 73 contracts and drives the mounting block 74 and the puncture needle 75 to retract as a whole into the cleaning roller 71. During the retraction process of the puncture needle 75, the extrusion block 19 made of elastic material in the needle hole of the cleaning roller 71 generates a radial extrusion force on the needle head of the puncture needle 75 due to its conical through-hole structure, so that the pus residue attached to the surface of the needle head is scraped and peeled off, and the waste liquid is blocked in the needle hole on the surface of the roller The edge of the cleaning roller 71 is rotated. At the same time, the continuous pressure of the spring 13 ensures that the scraping block 11 always fits the curved surface of the roller. The pus and ointment mixture attached to the surface of the rolling cleaning roller 71 is tightly scraped off by the adapting arc surface of the scraping block 11, and then the liquid suction pump 16 is activated. When the liquid suction pump 16 is working, a negative pressure is formed at the narrow and long liquid suction port on the side of the suction tube 15, and the waste liquid scraped by the scraping block 11 is efficiently sucked into the waste liquid box 14 for temporary storage. When the waste liquid box 14 needs to be cleaned, the user can manually pull the snap plates 18 on both sides of the shell 1 to release the locking of the card slot on the snap plate 18 on the protruding rod 141 of the waste liquid box 14, and then slide the waste liquid box 14 out along the mounting groove for disinfection or replacement.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
