Description

Technical Field

[0001] This utility model relates to beauty massage equipment, and in particular to a self-locking beauty handle with easily replaceable rollers. Background Technology

[0002] Existing beauty handpiece devices mostly adopt a fixed roller design, and their buckle structure is usually a closed circular buckle, which is rigidly connected to the roller through a fixed shaft. For example, in the "Roller Massager with Heating Function" disclosed in Chinese Utility Model Patent CN220833576U, the rollers can only be removed by forcibly prying open the roller brackets on both sides of the handle. During operation, the roller brackets are prone to deformation or breakage, affecting the service life.

[0003] In addition, the existing roller microneedle main structure is usually made of metal with densely arranged microneedles on the surface, such as Chinese utility model patent CN221513272U. These microneedles are fixed on the roller, and after long-term use, bacteria can easily grow due to incomplete cleaning or insufficient disinfection, which poses a risk of infection. The inability to replace them quickly also means that users need to frequently purchase the entire device, which is costly.

[0004] In addition, existing beauty handpieces have not been ergonomically optimized, making them neither comfortable nor flexible for users; their functions are limited and cannot meet the needs of multiple scenarios such as cold compresses, hot compresses, and massages.

[0005] Therefore, there is an urgent need for a beauty handpiece device that is simple in structure, easy to operate, supports quick replacement of rollers and microneedles, and has multiple functions, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The singular forms "a," "the," and "the" as used in the embodiments of this utility model are also intended to include the plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that although the terms first, second, third, etc., may be used to describe the acquisition modules in the embodiments of this utility model, these acquisition modules should not be limited to these terms. These terms are only used to distinguish the acquisition modules from each other.

[0044] Depending on the context, the word "if" as used here can be interpreted as "when," "when," "in response to determination," or "in response to detection." Similarly, depending on the context, the phrase "if determination" or "if detection (of the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when detection (of the stated condition or event)," or "in response to detection (of the stated condition or event)."

[0045] It should be noted that the directional terms such as "upper," "lower," "left," and "right" used in the description of the embodiments of this utility model are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. In addition, in the context, it should also be understood that when it is mentioned that an element is formed "upper" or "lower" of another element, it can not only be formed directly "upper" or "lower" of the other element, but also indirectly "upper" or "lower" of the other element through an intermediate element.

[0046] See Figure 1 One embodiment of this application discloses a self-locking beauty handle with easily replaceable rollers, including: a detachable roller assembly 101 and a handle 102, which can be configured as an integral structure, but are preferably configured as detachable and assembleable separate structures.

[0047] See Figure 2-3The roller assembly 101 has protruding retaining pins 103 at both ends along its central axis, which are typically cylindrical. Preferably, the middle section of the roller assembly 101 is cylindrical, while the left and right sections are conical with gradually decreasing diameters. The length of the middle section is greater than that of the left and right sections to ensure sufficient massage area. This configuration of the roller assembly 101 allows for convenient adjustment of the massage area in the middle section while maintaining a fixed length.

[0048] See Figure 2-3 The handle 102 includes a U-shaped mounting portion 1021 and a grip portion 1022. The U-shaped mounting portion 1021 has slots 104 at opposite ends that are adapted to the retaining shaft 103. Preferably, the slot 104 is a hollow cylindrical structure with a notch, the size of which matches the size of the retaining shaft 103, for example, the notch is slightly smaller than the retaining shaft 103, forming an interference fit. This allows the retaining shaft 103 to pass through the notch into the slot 104 under external force and form a rotatable connection with the slot 104. More preferably, the orientation of the notch in the slot 104 forms an angle of 30°-40° with the plane of the U-shaped mounting portion 1021. This embodiment uses an angle of approximately 37°, which ensures that the retaining shaft 103 is not easily dislodged from the slot 104 during massage. It should be noted that the "orientation of the notch" in this embodiment refers to the direction indicated by the midline of the notch angle.

[0049] See Figure 4 The beauty handle product also includes a receiving device 105 for the roller assembly 101, which has a groove adapted to the shape of the roller assembly 101. The size of the receiving device 105 allows the handle 102 to be inserted into the groove within a horizontal angle range of 30°-150°, thereby achieving interlocking assembly with the roller assembly 101 without removing the roller assembly 101.

[0050] See Figure 5 This embodiment features an ergonomic design for the beauty handle, with the plane of the U-shaped mounting portion 1021 and the axis of the grip portion 1022 forming an angle of 90°-180°. More preferably, the plane of the U-shaped mounting portion 1021 and the axis of the grip portion 1022 form an angle of 110°-160°, and a curved transition portion is provided between the U-shaped mounting portion 1021 and the grip portion 1022. On one hand, the aforementioned angle better conforms to the grip curve of the human hand, making the user comfortable to operate, reducing fatigue during prolonged use, and enhancing operational flexibility; on the other hand, the notch angle of the slot 104, the specific angle between the U-shaped mounting portion and the grip portion, and the shape of the receiving device, among other factors, work together to ensure that the handle can be inserted into the groove within a horizontal angle range of 30°-150° to achieve interlocking assembly with the roller assembly, facilitating the installation of the roller assembly and the handle.

[0051] Optionally, the handle 102 can be feather-shaped, spindle-shaped, or cylindrical, providing a comfortable grip. The handle 102 can be made of plastic, metal, ceramic, glass, wood, etc. Furthermore, the plastic materials include, but are not limited to: polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyethylene terephthalate, polycarbonate, polyamide, polyoxymethylene, polytetrafluoroethylene, acrylonitrile-butadiene-styrene copolymer, polyphenylene sulfide, polyetheretherketone, polymethyl methacrylate, etc. The metal materials include, but are not limited to: tool steel, stainless steel, aluminum alloy, copper alloy, titanium alloy, zinc alloy, etc. The ceramic materials include, but are not limited to: alumina, silicon carbide, silicate ceramics, silicon nitride, etc. The glass materials include, but are not limited to: borosilicate glass, tempered glass, etc.

[0052] Optionally, the roller assembly 101 may be made of materials including but not limited to: aluminum, copper, stainless steel, aluminum nitride, carbon fiber composite material, metal matrix composite material, polyamide, polyetheretherketone, graphite, Bian stone, and a combination of surface-coated silicone to meet different functional requirements.

[0053] Furthermore, to avoid bacterial growth caused by microneedles being fixed to the roller assembly 101 and the cost of frequent replacement of the entire device, this embodiment provides an adhesive area on the surface of the roller assembly 101 for quick attachment of disposable microneedle patches, thereby preventing cross-infection. Optionally, the disposable microneedle patches can also be replaced using magnetic or snap-fit ​​methods.

[0054] Furthermore, in order to meet the multi-functional and multi-scenario needs of the beauty handpiece, such as cold compress, hot compress, and massage, this embodiment provides a raised structure for massage on the surface of the roller assembly 101, and provides heating and cooling elements inside the roller assembly 101. When the roller assembly 101 rolls on the skin, the user can selectively achieve hot or cold compress effects through the switch button, and adjust the temperature of the heating and cooling elements through the control button to adapt to different hot or cold compress needs. The operation is simple and convenient.
