Description

TECHNICAL FIELD

[0001] The application relates to the technical field of acne cleaning, and in particular to an acne cleaning device for dermatology. BACKGROUND

[0002] Acne is a chronic inflammatory skin disease of the pilosebaceous unit, mainly occurring in adolescents, and has a great impact on the psychology and social interaction of adolescents, but can be naturally reduced or cured after puberty. The occurrence of acne is mainly related to excessive sebum secretion, blockage of the pilosebaceous duct, bacterial infection and inflammatory reaction and other factors. Acne not only occurs on the face but also on the back. Acne can affect the appearance of a person, thereby affecting the mood of people, and in severe cases, can leave scars. At present, part of the acne cleaning devices on the market are not easy to operate and control, which can cause secondary damage to the skin.

[0003] Specific analysis is as follows: I. Limitations of traditional treatment methods Significant drug side effects: Traditional oral drugs (such as antibiotics, isotretinoin) can cause skin irritation, erythema, peeling, and even systemic side effects (such as liver function damage). Although topical drugs have lighter side effects, they need to be used for a long time (at least 3 months), and are easy to cause skin barrier damage due to drug residues, increasing the risk of infection.

[0004] Low efficiency of physical treatment: Traditional physical methods such as squeezing and needle cleaning rely on manual operation, and have the problems of incomplete cleaning and easy scarring. For example, manual needle cleaning can cause uneven force, leaving propionibacterium acnes, and causing recurrence.

[0005] II. Growth of market demand Acne has a high incidence and is becoming younger. There are more than 600 million acne patients worldwide, and the incidence of Chinese adolescents reaches 85%. The incidence of adult population is increasing due to stress, diet and other factors. Patients urgently need a fast, safe and painless treatment solution.

[0006] Consumer upgrading drives technological innovation. With the improvement of residents' health awareness, consumers are more willing to pay for efficient and convenient medical and cosmetic products. The market for household acne cleaning devices is growing rapidly, driving the development of technology towards portability and intelligence.

[0007] The patent with the publication number CN 113476084B discloses a cleaning device, in particular relates to a dermatology acne cleaning device. The present application provides a simple operation, convenient to carry and can timely disinfect the skin part pierced by the device. The dermatology acne cleaning device comprises: a shell and a protruding mechanism, the shell is internally provided with the protruding mechanism; a needle, the protruding mechanism is provided with the needle; a medicine applying mechanism, the shell and the needle are provided with the medicine applying mechanism; a closing mechanism, the medicine applying mechanism and the shell are provided with the closing mechanism. The needle is moved to the left by manually pulling the sleeve, so that the first spring is compressed, and the needle is moved to the left to pierce the acne on the skin, realizing the protruding effect; the first piston rod is moved to the left by manually pushing, so that the liquid medicine in the first medicine storage tank can flow into the needle through the hose and be injected onto the acne, realizing the medicine applying effect.

[0008] However, the medicine applying mechanism in the application can only apply medicine after piercing the acne, cannot disinfect the piercing needle at the same time as the piercing needle moves downward, has the risk of cross infection, and cannot squeeze and clean the pierced acne, having the risk of acne residue. SUMMARY

[0009] In view of the above problems, the present application aims to provide a dermatology acne cleaning device, which can disinfect the piercing needle at the same time as the piercing needle moves downward, avoid cross infection, and squeeze and clean the pierced acne, avoiding acne residue, and having good treatment effect.

[0010] To achieve the above purpose, the technical scheme adopted by the present application is as follows: A dermatology acne cleaning device, comprising a shell, characterized in that it further comprises: A slope gradual pressing and piercing structure is arranged in the interior of the shell and is configured to generate a longitudinal thrust by lateral pressing to pierce the acne; A synchronous disinfection structure is arranged in the interior of the shell and is connected with the slope gradual pressing and piercing structure and is configured to move downward synchronously with the lateral pressing to squeeze disinfectant to the position to be disinfected at the bottom of the shell; A rotating squeezing and cleaning structure is arranged at the bottom of the shell and is configured to squeeze and clean the pierced acne by centrifugal force generated by rotation.

[0011] Further, the slope gradual pressing and piercing structure comprises: A gradual slope pressing combination is arranged on the outer surface of the shell and is connected with the interior of the shell and comprises a gradual slope pressing block and a return member connected with the gradual slope pressing block; The press-driven puncture component is located inside the housing and is engaged with the gradient ramp press block. It is configured to move downwards to puncture the acne as the longitudinal force generated by the lateral press of the gradient ramp press block is applied.

[0012] Furthermore, the press-activated puncture component includes: The support frame includes two support platforms, No. 1 and No. 2, which are arranged from top to bottom inside the shell, and the No. 1 support platform is connected to the No. 2 support platform. The socket cavity, located below the No. 2 receiving platform, includes a socket driving cavity and a socket disinfection cavity located below the socket driving cavity. The piercing insert is nested inside the sterilization chamber and includes a piston plate and a piercing needle located below the piston plate. An elastic element is provided between the piston plate and the piercing needle.

[0013] Furthermore, the puncture needle is equipped with a disinfection and drainage device, which includes a drainage groove on the puncture needle and a limiting ring located below the drainage groove.

[0014] Furthermore, the sleeve drive cavity includes a squeezing cavity and a collecting cavity sleeved in the squeezing cavity, and the squeezing cavity and the collecting cavity are connected. The outer diameter of the No. 2 receiving platform matches the inner diameter of the extrusion chamber.

[0015] Furthermore, the simultaneous disinfection structure includes: The disinfectant storage chamber is located below the No. 1 receiving platform, with a nesting reserved area in the middle and multiple openings at the bottom; The assembly of multiple connecting tubes includes multiple connecting tubes, the positions of which correspond to multiple openings and are evenly distributed on the inner wall of the shell. Each connecting tube has one end connected to an opening and the other end connected to a rotary extrusion cleaning structure.

[0016] Furthermore, the rotary extrusion cleaning structure includes: The drive motor is located in the nested reserved area and has an upper output shaft and a lower output shaft. The connecting rod is connected to the lower output shaft at one end and extends to the bottom of the housing at the other end; The driven extrusion assembly, located at the bottom of the housing and connected to the connecting rod, includes an elastic element and a sterile cotton pad located below the elastic element.

[0017] Furthermore, the elastic element includes a plurality of elastic sheets arranged in a radiating pattern from bottom to top, and an extension groove is provided on the elastic sheet corresponding to the connecting tube.

[0018] Furthermore, a dermatological acne treatment device also includes: An adaptive blowing and suction auxiliary structure is located outside the housing and connected to the rotary extrusion cleaning structure. It is configured to generate negative pressure or blowing air simultaneously while the rotary extrusion cleaning structure is rotating to assist in cleaning.

[0019] Furthermore, the adaptive blow-suction assist structure includes: The pressure chamber is located at the upper end of the drive motor, and a fan is installed inside it. The fan is connected to the upper output shaft. The air supply duct is located on the outer wall of the housing, with one end connected to the pressure chamber and the other end facing the bottom of the disinfection cotton pad.

[0020] Compared with the prior art, the beneficial effects of the present invention are: By combining the sloping, gradually pressing puncture structure with the simultaneous disinfection structure, acne puncture and disinfection are completed simultaneously. Specifically, the lateral pressing is transformed into a precise longitudinal puncture motion through the sloping structure. Combined with the disinfection drainage device on the puncture needle, disinfectant can be applied to the needle body through the drainage groove at the moment of puncture. This integrated design effectively solves the problems of bacterial residue and cross-infection caused by the separate puncture and disinfection procedures in traditional operations.

[0021] This cleaning mechanism combines rotary squeezing with adaptive blowing and suction. A drive motor rotates an elastic element, generating centrifugal force that evenly squeezes the sterile cotton pad onto the punctured acne. Simultaneously, a connecting tube continuously delivers disinfectant to the treatment area. A reversible drive motor also powers a fan, creating negative pressure suction or positive airflow within the pressure chamber. This effectively removes lesions from the edges of the sterile cotton pad while preventing secondary contamination. This dynamic cleaning method significantly improves the efficiency of acne removal.

[0043] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] Acne is a chronic inflammatory skin disease of the pilosebaceous unit, mainly affecting adolescents. It has a significant impact on the psychology and social life of teenagers, but it often improves or heals naturally after puberty. The occurrence of acne is closely related to factors such as excessive sebum secretion, blockage of the pilosebaceous duct, bacterial infection, and inflammatory response. Acne can occur not only on the face but also on the back. Acne affects a person's appearance, thereby affecting their mood, and in severe cases, it can leave scars.

[0045] Currently, traditional physical methods such as squeezing and needle extraction rely on manual operation, which can lead to incomplete removal and scarring. For example, manual needle extraction may result in uneven pressure, leaving behind Propionibacterium acnes and causing recurrence. Therefore, please refer to [link to relevant documentation]. Figures 1-14This application discloses a dermatological acne treatment device, including a housing 1. An upper protective shell 2 and a lower protective shell 3 are threadedly connected to both ends of the housing 1. The housing 1, upper protective shell 2, lower protective shell 3, and all internal components without specific description are made of medical-grade plastic. The housing 1 is a smooth, multifaceted shape suitable for handheld use, with a nearly circular cross-section. Figure 1 Taking the acne cleaning device of this application as an example, its height is 115mm and its width (maximum diameter) is 30mm.

[0046] It also includes: a ramp-gradient pressing puncture structure, located inside the housing 1, configured to puncture acne by pushing longitudinally through lateral pressing; the ramp-gradient pressing puncture structure protrudes from the surface of the housing and is covered with a soft rubber shell for easy manual pressing; a synchronous disinfection structure, located inside the housing 1 and connected to the ramp-gradient pressing puncture structure, configured to move downwards simultaneously while being pressed laterally, squeezing the disinfectant to the bottom of the housing 1 to be disinfected; and a rotating squeezing cleaning structure, located at the bottom of the housing 1, configured to squeeze and clean the punctured acne using the centrifugal force generated by rotation.

[0047] The sloping gradient pressing puncture structure includes: a gradient slope pressing assembly, which is located on the outer surface of the housing 1 and communicates with the interior of the housing 1, and includes a gradient slope pressing block 19 and a reset member connected to the gradient slope pressing block 19; the reset member includes a support rod 21 sleeved on the lower end of the gradient slope pressing block 19 and a first spring 20 sleeved on the support rod 21, and the slope of the gradient slope pressing block 19 gradually decreases from top to bottom.

[0048] The press-driven puncture component is located inside the housing 1 and is engaged with the gradient ramp press block. It is configured to move downwards to puncture the acne as the longitudinal force generated by the lateral press of the gradient ramp press block is applied.

[0049] By pressing the gradient ramp pressing block 19 laterally, the gradient ramp decomposes the lateral force into a lateral pushing force and a longitudinal displacement force. As a result, the pressing driven puncture component that is engaged with the gradient ramp pressing block 19 moves downward. During the lateral pressing process, the gradient ramp pressing block 19 compresses the first spring 20 sleeved on the support rod 21, causing the first spring 20 to store force. After the pressing stops, the first spring 20 will drive the gradient ramp pressing block 19 to automatically return to its original position, thereby causing the pressing driven puncture component to quickly reset. This means that the needle can be quickly inserted to puncture the acne during pressing and can be quickly withdrawn after puncturing.

[0050] Specifically, the press-driven puncture assembly includes: a receiving frame, comprising two receiving platforms 26 and 27 arranged from top to bottom inside the housing 1, and the edges of the receiving platform 26 and the receiving platform 27 are fixedly connected by multiple connecting rods 28, so that the receiving platform 26 and the receiving platform 27 can move synchronously. The socket cavity, located below the second receiving platform 27, includes a socket driving cavity and a socket disinfection cavity located below the socket driving cavity; wherein, the socket driving cavity includes a squeezing cavity 13 and a collection cavity 14 sleeved in the squeezing cavity 13, and the squeezing cavity 13 and the collection cavity 14 are connected; the socket disinfection cavity includes a first cavity 17 and a second cavity 31 sleeved in the first cavity 17, and the first cavity 17 and the second cavity 31 are connected.

[0051] The piercing insert is nested inside the collection chamber 14 and includes a piston plate and a piercing needle 15 located below the piston plate. An elastic element is provided between the piston plate and the piercing needle 15. The elastic element is specifically a second spring 16, which can enable the piercing needle 15 to quickly return to its original position after completing the piercing task, so as to facilitate the next piercing.

[0052] It should be noted that one end of the puncture needle 15 is located inside the collection chamber 14, and the other end passes through the second chamber 31, which facilitates the disinfection of the needle body of the puncture needle 15.

[0053] The first receiving platform 26 is located above the second receiving platform 27, which is located above the squeezing chamber 13. The outer diameter of the second receiving platform 27 matches the inner diameter of the squeezing chamber 13, so that when the first receiving platform 26 and the second receiving platform 27 move downward, they can push the air in the squeezing chamber 13 into the collection chamber 14 connected to the squeezing chamber 13. Then, they push the piston plate nested in the collection chamber 14, which in turn drives the piercing needle 15 connected to it to move downward, so that the piercing needle 15 can pierce the acne.

[0054] More specifically, the puncture needle 15 is equipped with a disinfection drainage device, which includes a drainage groove 29 on the puncture needle 15 and a limiting ring 30 located below the drainage groove 29. The limiting ring 30 is fixedly installed at the bottom of the second cavity 31 and sleeved on the puncture needle 15 to prevent the disinfectant from leaking out when not puncturing. The drainage groove 29 is opened on both sides of the puncture needle 15, which can guide the disinfectant in the second cavity 31 to the needle body of the puncture needle 15 through the drainage groove 29 when the puncture needle 15 moves downward, thereby allowing the disinfectant to wet and disinfect the entire puncture needle 15.

[0055] In order to simultaneously disinfect the bottom of the shell 1 when the gradient ramp pressing block 19 is pressed laterally, this application also provides a simultaneous disinfection structure, which specifically includes: a disinfectant storage cavity 12 located below the first receiving platform 26, with a nesting reserved area in the middle and multiple openings at the bottom; multiple connecting pipe assemblies, corresponding to the multiple openings, evenly distributed on the inner wall of the shell 1, wherein one end of each connecting pipe assembly is connected to an opening and the other end is connected to the rotary extrusion cleaning structure.

[0056] Specifically, the connecting pipe assembly includes multiple connecting pipes 18 evenly distributed inside the housing 1, and one end of each connecting pipe 18 is connected to an opening, and the other end is connected to a rotary extrusion cleaning structure.

[0057] The disinfectant inside the disinfectant storage chamber 12 can flow into the connecting pipe 18 through the opening at the bottom under the influence of gravity, and then flow into the rotating squeezing cleaning structure through the connecting pipe 18 to disinfect it.

[0058] It should be noted that an injection hole is provided on the outer wall of the shell 1, which is connected to the disinfectant storage cavity 12, so as to facilitate timely replenishment of disinfectant to the inside of the disinfectant storage cavity 12.

[0059] Specifically, the rotary extrusion cleaning structure includes: a drive motor 9, located in the nested reserved area, with an upper output shaft 10 and a lower output shaft 11; a connecting rod, one end of which is connected to the lower output shaft 11, and the other end extending to the bottom of the housing 1; and a driven extrusion assembly, located at the bottom of the housing 1 and connected to the connecting rod, including an elastic element and a disinfectant cotton pad 8 located below the elastic element. The disinfectant cotton pad 8 is a disposable consumable, which is fixed by a buckle 7 and a fastening groove at the bottom of the housing that matches the buckle 7. After use, the buckle 7 can be removed to release the restriction on the disinfectant cotton pad 8, and then a new disinfectant cotton pad 8 can be placed at the bottom of the housing 1. The buckle 7 can then be fastened to the fastening groove at the bottom of the housing 1 to restrict the new disinfectant cotton pad 8.

[0060] The elastic element includes a plurality of elastic sheets 25 arranged in a radiating pattern from bottom to top. Furthermore, the upper surface of the elastic sheet 25 corresponding to the connecting pipe 18 is provided with an extension groove 33. The extension groove 33 extends directly to the bottom of the elastic sheet 25, so that the disinfectant in the connecting pipe 18 can flow into the bottom of the elastic sheet 25 through the extension groove 33. As the disinfectant flows continuously, it can then soak and disinfect the disinfectant cotton pad 8 located below the elastic element.

[0061] It should be noted that the bottoms of the elastic sheets 25 are gathered together, and a cylindrical extrusion groove 32 with an internal cavity is provided at the bottom of the gathered elastic sheets 25. The outside of the extrusion groove 32 is welded to the bottoms of the multiple elastic sheets 25.

[0062] It should also be noted that during the puncture operation, the tip of the puncture needle 15 will also puncture the sterile cotton pad 8 at the bottom of the shell 1. During the reciprocating puncture of the puncture needle 15, the sterile cotton pad 8 can scrape the residue on the puncture needle 15 onto the outside of the sterile cotton pad 8, preventing the puncture needle 15 from bringing the residue into the shell for the next puncture, thereby preventing cross-infection.

[0063] When the drive motor 9 rotates, it can drive the connecting rod connected to the lower output shaft 11 to rotate, which in turn drives the elastic element to rotate. Since each elastic piece 25 is made of spring steel with a thickness of 0.5mm, when rotating, under the action of centrifugal force, the bottom of the elastic piece 25 will drive the squeezing groove 32 to move downward. During the downward movement, the squeezing groove 32 squeezes the disinfectant cotton pad 8 located below the elastic element. The squeezing groove 32 uses its own shape to squeeze out the lesion material inside the punctured acne through the disinfectant cotton pad 8. At the same time, the disinfectant liquid on the disinfectant cotton pad 8 is evenly applied to the squeezed acne area by rotation, so that the disinfection operation can be completed at the same time as squeezing.

[0064] In order to treat the lesions on the disinfectant cotton pad 8, the dermatological acne cleaning device of this application further includes: an adaptive blowing and suction auxiliary structure, which is located outside the housing 1 and connected to the rotary squeezing cleaning structure. It is configured to generate negative pressure or blowing air simultaneously while the rotary squeezing cleaning structure is rotating to assist in cleaning.

[0065] Specifically, the adaptive blowing and suction auxiliary structure includes: a pressure chamber 23 located at the upper end of the drive motor 9, which is equipped with a fan 22 and connected to the upper output shaft 10; and an air supply pipe 5 located on the outer wall of the housing 1, with one end connected to the pressure chamber 23 and the other end facing the bottom of the disinfection cotton pad 8.

[0066] The drive motor 9 drives the fan 22 to rotate, creating a negative pressure in the pressure chamber 23. This causes the air supply pipe 5, which is connected to the pressure chamber 23, to generate suction, drawing the pathogenic material at the bottom of the disinfectant cotton pad 8 towards its edge. Furthermore, the drive motor 9 can also reverse, causing the air supply pipe 5, connected to the pressure chamber 23, to generate a blowing force, blowing away and removing the pathogenic material adsorbed at the bottom of the disinfectant cotton pad 8, thus reducing the risk of cross-infection. Example

[0067] This dermatological acne treatment device is suitable for clinical acne treatment in medical institutions, and is particularly suitable for treating inflammatory acne lesions on the face, back, and other areas.

[0068] During operation, medical personnel first inject sufficient disinfectant into the disinfectant storage chamber 12 through the injection hole on the side wall of the housing 1, and then place the bottom of the device against the acne area in preparation for the operation. In the initial state, the puncture needle is completely retracted inside the housing 1, the disinfectant cotton pad 8 is in a naturally unfolded state, and the entire device is in a standby safe state.

[0069] The specific operation process is as follows: First, the sloping gradient pressure puncture structure is activated: Medical personnel press the sloping gradient pressure block 19 laterally. The gradually changing slope converts the lateral thrust into longitudinal displacement, causing the first receiving platform 26 and the second receiving platform 27 to move downwards simultaneously. This action compresses the air in the squeezing chamber 13, pushing the piston plate and causing the puncture needle 15 to puncture the acne lesion downwards. At the same time, the drainage groove 29 on the surface of the puncture needle 15 cooperates with the limiting ring 30, allowing the disinfectant in the second chamber 31 to continuously wet the needle body, achieving puncture and simultaneous disinfection. After the puncture is completed, the sloping gradient pressure block 19 is released, and the first spring 20 drives the sloping gradient pressure block 19 to quickly reset, and the puncture needle 15 automatically retracts into the device.

[0070] The subsequent rotary squeezing cleaning phase begins: the drive motor 9 rotates the connecting rod via the lower output shaft 11, causing the elastic sheet 25 to bend downwards under centrifugal force, pushing the disinfectant cotton pad 8 to evenly squeeze the punctured acne. During this process, disinfectant is continuously delivered to the operating area through the connecting pipe 18 and the extension groove 33, achieving simultaneous cleaning and disinfection of lesions. Simultaneously, the adaptive blowing and suction auxiliary structure activates; the fan in the pressure chamber 23 rotates with the upper output shaft 10 to generate negative pressure, which draws the squeezed-out lesions to the edge of the disinfectant cotton pad 8 through the air supply pipe 5. When the drive motor 9 reverses direction, the fan 22 blows the remaining material forward away from the operating area through the air supply pipe 5, completing the final cleaning.

[0071] This device achieves standardized operation through mechanical linkage, and its integrated design effectively avoids the uneven force problem of traditional needle extraction techniques. It is particularly suitable for the adjunctive treatment of nodular acne; when used in conjunction with medication, it can shorten the healing cycle, and the procedure eliminates the need for repeated instrument changes, significantly reducing the risk of cross-infection.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
