Description

Technical Field

[0001] This utility model relates to the field of minoxidil applicator technology, and in particular to a minoxidil liniment applicator with scalp massage function. Background Technology

[0002] Minoxidil topical solution, a commonly used clinical treatment for hair loss, needs to be applied directly to the affected scalp using an applicator to ensure its efficacy. Most commercially available minoxidil topical applicators consist of a reservoir, a dispensing tube, and an applicator head. Their core function is the quantitative delivery and initial application of the medication, relying on the applicator head to evenly distribute the medication onto the scalp surface during use.

[0003] In practical applications, the absorption of minoxidil is closely related to the depth of its penetration into the scalp. Clinically, it is recommended to massage the scalp after application to promote absorption. Existing applicators only perform the application and lack massage functionality, requiring users to massage with their fingers after application. This method has significant drawbacks: firstly, finger massage requires separate time, and the massage intensity and frequency are difficult to maintain consistently, especially for users with large areas of hair loss or those performing the procedure themselves, making it extremely inconvenient; secondly, bacteria, oil, and external contaminants easily adhere to the surface of the fingers, potentially contaminating incompletely absorbed medication during massage, leading to drug deterioration and ineffectiveness, and may also cause scalp follicle infections, affecting treatment efficacy and scalp health. Furthermore, some users have excessively long nails or uneven nail edges, which can easily scratch the scalp during massage, further increasing the risks. Utility Model Content

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please see Figure 1-4 This utility model provides a minoxidil liniment applicator with scalp massage function, comprising: a housing 1, a first support plate 2, a second support plate 3, a massage mechanism 4, and a drive mechanism. The housing 1 is the core load-bearing component of the entire applicator, providing stable installation support for all internal structures. An end cap 11 is threadedly connected to the upper end of the housing 1, achieving a sealed protection for the reservoir 12, preventing the medication from evaporating, contaminating, or leaking when not in use. The threaded connection also facilitates user disassembly to add medication to the reservoir 12. The reservoir 12, located inside the housing 1, is the storage space for the minoxidil liniment, continuously providing a source of medication during application. Its volume design is adapted to the regular medication cycle, reducing the inconvenience of frequent refills. The first support plate 2 and the second support plate 3 are both fixedly installed inside the housing 1, with the second support plate 3 located below the first support plate 2. The first support plate 2 primarily supports the motor 5, providing stable support for power output. The second support plate 3 serves as the mounting base for the massage mechanism 4. By fixing components such as the rotating shaft 41 and the bracket 46, it ensures the structural stability and precise movement of the massage mechanism 4 during operation. The massage mechanism 4 has a drive guide part located on the lower side wall of the second support plate 3 and a massage part located at the bottom of the housing 1. It is the core component for realizing the scalp massage function. It drives the massage head 45 to move through mechanical transmission, massaging the scalp while applying medicine, thus solving the defect of traditional applicators that require additional massage.

[0031] To further explain, an annular silicone sealing ring is provided on the inner side of the end cap 11. When the end cap 11 is tightened, the sealing ring fits tightly against the upper end face of the housing 1, thereby achieving sealing protection of the liquid storage chamber 12.

[0032] To further explain, a rechargeable lithium battery (not shown in the figure) is housed within the side wall of housing 1, and a Micro-USB charging port (not shown in the figure) and a power switch (not shown in the figure) are located on the outer surface of housing 1. The lithium battery powers motor 5. The Micro-USB charging port charges the lithium battery. The power switch controls the start and stop of motor 5. This is mature existing technology, and the specific circuitry and structure will not be elaborated upon here.

[0033] To further explain, the drive guide of the massage mechanism 4 includes four rotating shafts 41 ringed around the second support plate 3, a drive seat 42 fixed at the lower end of the rotating shafts 41, four supports 46 ringed around the lower side wall of the second support plate 3, a first turntable 47 rotating on the inner walls of both sides of the support 46, two L-shaped connecting rods 48 fixed on the first turntable 47, a follower plate 49 fixed at the other end of the L-shaped connecting rods 48, and a connecting rod 410 rotatably connected to the follower plate 49. The rotating shafts 41 serve as the power transmission medium, with the upper end connected to the driven gear 411 and the lower end driving the drive seat 42 to rotate, converting gear transmission into rotational motion of the drive component. The inclined structure of the drive seat 42 provides the motion trajectory for the drive rod 43 of the massage part, which is the "key to power conversion" of the massage action. The bracket 46, the first turntable 47, the L-shaped connecting rod 48, the follower plate 49, and the connecting rod 410 form a "guided linkage structure". The bracket 46 fixes the rotation axis of the first turntable 47. The L-shaped connecting rod 48 converts the rotation of the first turntable 47 into the translation of the follower plate 49. The follower plate 49 then limits the movement direction of the drive rod 43 through the connecting rod 410, ensuring that the drive rod 43 only moves along the "reciprocating trajectory close to the scalp" to avoid deviation that could cause the massage head 45 to scratch the scalp or cause uneven massage.

[0034] Further explanation: The massage unit of the massage mechanism 4 includes a drive rod 43 rotatably mounted on the inclined surface of the drive seat 42, a base 44 extending from the housing 1 and fixed thereon, and several massage heads 45 mounted on the base 44. The other end of the connecting rod 410 is fixedly connected to the drive rod 43. The massage unit converts the power of the drive guide into a massage action that directly acts on the scalp, while ensuring the safety and comfort of the massage. The drive rod 43 is a "power transmission bridge." One end is attached to the inclined surface of the drive seat 42 and is pushed by the inclined surface to perform a reciprocating motion as the drive seat 42 rotates. The other end is connected to the base 44, transmitting the reciprocating motion to the massage heads 45. The base 44 provides a mounting carrier for the massage heads 45, ensuring that multiple massage heads 45 move synchronously. The massage heads 45 directly contact the scalp, achieving a massage effect through reciprocating pressure. Combined with the "fingerless" design, it fundamentally avoids contamination of the medication or scalp by bacteria from the fingers.

[0035] To further explain, the massage head 45 is made of medical-grade silicone, which has good elasticity and biocompatibility, can avoid scalp allergies, and is resistant to chemical corrosion.

[0036] To further explain, the drive mechanism includes a motor 5 mounted at the center of the upper side wall of the first support plate 2, a drive gear 51 whose output shaft passes through and is fixed to the first support plate 2, and a driven gear 411 fixed to the upper end of the rotating shaft 41 and meshing with the drive gear 51. The motor 5 is the power source for the entire massage mechanism 4; its output shaft rotation generates power, providing continuous driving force for the massage motion. The motor 5 is a miniature DC motor. Through the meshing transmission of the drive gear 51 and the driven gear 411, the power of the motor 5 is evenly transmitted to the four rotating shafts 41, achieving synchronous movement of the four massage units and ensuring consistency in massage intensity and frequency.

[0037] To further explain, the dispensing tube 13 is connected to the lower outer wall of the reservoir 12, serving as a drug delivery channel to guide the minoxidil lotion in the reservoir 12 to the scalp surface. The application roller 14 is located at the lower end of the dispensing tube 13 and uses a rolling contact method. On the one hand, it can control the flow rate of the drug, avoiding excessive waste or uneven application. On the other hand, the rolling action achieves initial application of the drug, and compared to a rigid application head, it can reduce friction damage to the scalp.

[0038] To further explain, the massage head 45 is conical with a rounded bottom. The conical structure facilitates movement among the scalp and hair, ensuring full contact with the scalp. The rounded surface design avoids scratches to the scalp from sharp edges, while increasing the massage contact area, improving massage comfort and effectiveness, and further ensuring medication safety.

[0039] To further explain, the outer surface of the housing 1 is provided with scale lines for indicating the dosage of minoxidil liniment in the reservoir 12.

[0040] To further explain, the shell 1 is made of transparent plastic, and with the scale lines on the outer surface, the remaining dose of minoxidil lotion in the reservoir 12 can be clearly displayed, making it convenient for users to replenish the medication in a timely manner and avoid affecting the treatment effect due to insufficient dosage.

[0041] To further explain, a rubber sleeve 6 is provided between the bottom wall of the housing 1 and the base 44. The rubber sleeve 6 is made of elastic silicone material and fits tightly against the bottom wall of the housing 1 and the base 44. On the one hand, it prevents external dust, moisture or pollutants from entering the interior through the gap between the housing 1 and the base 44. On the other hand, it can prevent hair from getting tangled.

[0042] It should be noted that this utility model is a minoxidil liniment applicator with a scalp massage function. In use, the user first unscrews the end cap 11 at the upper end of the housing 1 and adds minoxidil liniment to the reservoir 12 inside the housing 1. During the application process, the dosage can be observed through the scale lines on the outer surface of the housing 1 to avoid over-application. After application, the end cap 11 is threaded back onto the housing 1 to ensure the reservoir 12 is sealed. In use, the motor 5 on the first support plate 2 is started. The output shaft of the motor 5 drives the fixedly connected drive gear 51 to rotate. Since the drive gear 51 meshes with the driven gears 411 at the upper ends of the four rotating shafts 41, the rotational power of the drive gear 51 is transmitted to the four rotating shafts 41 through gear transmission, causing the rotating shafts 41 to rotate synchronously. The rotation of the rotating shafts 41 drives the drive seat 42 fixed at the lower end to rotate synchronously, and the inclined surface of the drive seat 42 drives the drive rod 43 to reciprocate axially. During this process, the first turntable 47, L-shaped connecting rod 48, follower plate 49, and connecting rod 410 within the support 46 on the lower side wall of the second support plate 3 form a guiding structure, restricting the movement trajectory of the drive rod 43 and ensuring its stable reciprocating motion. The end of the drive rod 43 away from the drive seat 42 drives the base 44 and several massage heads 45 on the base 44 to reciprocate synchronously. The conical bottom arc surface of the massage head 45 contacts the scalp, achieving scalp massage through reciprocating motion. While the massage head 45 massages the scalp, the user places the lower end of the housing 1 close to the scalp, and the minoxidil lotion in the reservoir 12 flows under gravity through multiple outlet tubes 13 to the application roller 14 at the lower end of the outlet tube 13. When the user pushes the applicator to move on the affected area of ​​the scalp, the application roller 14 rolls, evenly distributing the medication on the scalp surface, achieving simultaneous application and massage. After medication is applied, the motor 5 is turned off, and the massage mechanism 4 stops moving. Users can clean the exterior of the housing 1, especially the base 44, massage head 45 and application roller 14, to avoid drug residue contamination, and then store the applicator in a dry and clean place for later use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
