[0005] This invention aims to overcome the shortcomings of existing beauty devices, such as difficult roller replacement, limited performance, low automation, and reduced user experience. It provides a roller beauty device with easily replaceable rollers, enhanced performance, and improved automation, thereby improving the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A roller beauty device, including

[0008] The housing has a magnetic mounting base connected to one side and a transmission mounting base connected to the other side.

[0009] The roller head has a mating seat at one end and a mounting shaft at the other end. Both the mating seat and the magnetic mounting seat are connected to magnetic connectors and are magnetically connected. The mounting shaft is slidably connected to the transmission mounting seat.

[0010] The transmission module has a bracket connected to the inner cavity of the housing. The transmission module is connected to the bracket, and the transmission mounting base is rotatably connected to the housing through the transmission module.

[0011] The control module is detachably connected to the housing and electrically connected to the transmission module.

[0012] The EMS module includes a positive electrode and a negative electrode, both of which are connected to the housing.

[0013] The housing features two pairs of sides, one side of which is equipped with a magnetic mounting base for connecting to the mounting base on the roller head. These bases are connected via compatible magnetic connectors. The other side connects to a transmission mounting base for inserting a mounting shaft, allowing for quick assembly and disassembly of the roller head for easy replacement. This ensures the beauty device is compatible with different types of roller heads. An internal transmission module drives the transmission mounting base to rotate, which in turn rotates the mounting shaft synchronously, ensuring stable rotation of the roller head. A control module switches the transmission module between motorized states, providing energy and control, enabling automatic rotation of the roller head. An EMS module with positive and negative electrodes is mounted on the housing to stimulate the skin, tightening it and reducing swelling, further enhancing the device's functionality when used with the roller head. This design achieves efficient assembly and disassembly of the roller head, improved device performance, stable assembly of components, automated roller head rotation, and a better user experience.

[0014] Preferably, the housing has an installation port 1 that communicates with the inner cavity of the housing. A limit bracket is connected to the inner cavity of the housing. The magnetic mounting seat is embedded with the limit bracket. The magnetic mounting seat has a limit groove 1. The housing is snapped into the limit groove 1 through the installation port 1. A sealing ring is fitted onto the magnetic mounting seat. The mating seat has an installation groove 1. The magnetic mounting seat has an installation groove 2. The cross-sectional shape of the installation groove 1 and the installation groove 2 is circular. The magnetic connector includes a magnetic block 1 and a magnetic block 2. The magnetic block 1 is connected to the installation groove 1, and the magnetic block 2 is connected to the installation groove 2. The housing is positioned by a pair of magnetic mounting seats with mounting openings. The magnetic mounting seat has an inwardly recessed annular groove in the center, giving it an I-shaped cross-section. The rear end of the magnetic mounting seat is embedded in a limiting bracket, and the front end extends out of the mounting opening for connection with the mating seat. A sealing ring is fitted into the limiting groove to enhance the sealing of the mounting opening. A magnetic block is fixed to the mating seat via mounting groove one, and a magnetic block is fixed to the magnetic mounting seat via mounting groove two. When installing the roller head, the mating seat and the magnetic mounting seats face each other, and the magnetic blocks attract and hold each other. This improves the assembly stability and sealing of the components, enhances the connection stability of the magnetic connectors, and ultimately improves the assembly efficiency of the roller head.

[0015] Preferably, the housing has a second mounting opening, and the transmission mounting seat has a second limiting groove. The housing engages with the second limiting groove via the second mounting opening. The transmission mounting seat has a third mounting groove. Both the third mounting groove and the mounting shaft have rectangular cross-sectional shapes, and the mounting shaft is slidably connected to the third mounting groove. The housing has a second mounting opening on the opposite side of the first mounting opening. The second limiting groove is an annular recess on the end surface of the transmission mounting seat, allowing the transmission mounting seat to be inserted into the second mounting opening. The third mounting groove is an opening on the end face of the transmission mounting seat, allowing the mounting shaft to overcome stress and be inserted into the third mounting groove. The rectangular shape of the third mounting groove and the cross-sectional shape of the mounting shaft prevent the roller head from wobbling and allow it to rotate synchronously. The magnetic connector, in a magnetically attracted state on the other side, connects the mounting shaft close to the opening of the third mounting groove. By sliding the mounting shaft out of the third mounting groove, the magnetic attraction between the first and second magnetic blocks can be broken, allowing the roller head to be quickly removed for replacement. This achieves the effects of improving the assembly stability of the mounting shaft, ensuring the mobility of the roller head, and facilitating the efficiency and convenience of assembly and disassembly.

[0016] Preferably, the housing has an end cap connected to a locking block. The housing has a locking groove, and the locking block engages with the locking groove. The end cap has two clearance holes: a first clearance hole and a second clearance hole. The magnetic mounting base is placed in the first clearance hole, and the transmission mounting base is placed in the second clearance hole. The structural shape of the end cap is adapted to the roller head. The surface curve of the end cap is smooth and adapts to the structural shape of the roller head. The housing is formed by the locking of two halves of the housing. The engagement of the end cap with the locking block and the locking groove enhances the tightness of the housing connection. The smooth and complete surface of the end cap covers the recessed area of ​​the housing, ensuring a beautiful and smooth line at the roller head. There is no seam below the roller head. On opposite sides of the end cap, clearance hole one provides space for the magnetic mounting base, and clearance hole two provides space for the transmission mounting base, for later installation of the roller head. This achieves the effects of improving the tightness of the component connection, the smooth curve of the equipment, and enhancing the user experience.

[0017] Preferably, the transmission module includes a conveyor belt, a tension roller, and a support plate. The support plate has several rotating holes, into which several rollers are inserted. The control module includes a rotating mechanism connected to a drive roller. The transmission mounting base, tension roller, and drive roller are respectively inserted into the rollers. Each of the transmission mounting base, tension roller, and drive roller has a limiting groove, and the conveyor belt is fitted into the limiting groove. The tension roller is positioned between the transmission mounting base and the drive roller. The conveyor belt surrounds the limiting groove in the middle of the transmission mounting base, tension roller, and drive roller, limiting the transmission belt. The tension roller tightens the conveyor belt. The rollers, through the support plate, provide a rotation fulcrum for the transmission mounting base, tension roller, and drive roller. The rotating mechanism provides driving force to the drive roller. The friction of the conveyor belt drives the transmission mounting base and tension roller to rotate synchronously, ensuring that the roller heads on the mounting shaft rotate synchronously for automatic rolling massage. This achieves stable installation and fit between components and stable motorized drive.

[0018] Preferably, the support plate has several fixing slots, with the bracket inserting into these slots. The rotating mechanism is connected to a fixed bracket, and the housing has two fixing slots, with the fixed bracket inserting into these slots. The support plate has several fixing slots to match the brackets on the housing, allowing the support plate to be fixedly positioned by inserting into the brackets through the fixing slots, thus securing the transmission module. Meanwhile, the inner wall of the housing has two fixing slots to fix the fixed brackets connected to the rotating mechanism. This improves the stability of component assembly and facilitates disassembly and maintenance.

[0019] Preferably, the control module includes a power button, a PCB board, a switching element, and a battery module. A button bracket is bolted to the inner cavity of the housing. The button bracket has a positioning groove. One end of the power button is engaged with the positioning groove. The housing has a button opening. The other end of the power button is placed at the button opening. The power button is connected to a sealing ring that abuts against the inner wall of the housing. The PCB board is bolted to the housing. The switching element and the battery module are electrically connected to the PCB board. The rotating mechanism is electrically connected to the PCB board. The rotating mechanism, the positive electrode plate, and the negative electrode plate are all electrically connected to the PCB board. The power button is movably connected to the switching element. A charging socket is bolted to the inner cavity of the housing. The mounting bracket is bolted to the inner cavity of the housing to embed the power button via a positioning slot. The outer part of the power button protrudes from the button opening in the housing for easy pressing to control the switch. After the power button is connected, a sealing ring is pressed against the inner wall of the housing, placing the button opening within the diameter of the sealing ring and sealing the housing opening. The PCB board is bolted to the inner cavity of the housing. The switching elements and battery module are electrically connected to the PCB board, allowing the power button to activate the power supply via a tactile switch. The battery module powers the PCB board, enabling the rotating mechanism and EMS module to open or close via signals from the PCB board. The charging dock allows for portable use of the beauty device. This design improves the stability and sealing of the component assembly, ensures stable assembly and operation of electrical components, and facilitates portability.

[0020] Preferably, the roller head has a hollow structure made of a light-transmitting material. An LED is connected inside the roller head cavity. A magnetic block one is connected to a wire one, which is electrically connected to the PCB board. A magnetic block two is connected to a wire two, which is electrically connected to the LED. The roller head is made of a light-transmitting material, and the LED is installed inside. The LED's display light is controlled by the contact points of magnetic blocks one and two via the PCB board and magnetic connectors. This ensures stable contact and illumination, improving the user experience.

[0021] Preferably, the roller head is made of metal. The metal provides a cooling effect, and the mounting base and shaft are installed and replaced on both sides of the roller head to apply a cooling effect to the skin through rolling. This achieves both the flexibility of roller head replacement and the cooling effect of the beauty device.

[0022] Preferably, the roller head has several roller needles attached to its surface. These roller needles are evenly distributed on the surface of the roller head, allowing the roller head mounting base and mounting shaft to be installed and replaced on both sides of the roller head with the roller needles, respectively, so that the skin receives a deep massage through rolling. This achieves flexibility in roller head replacement and provides a deep massage effect for the beauty device.

[0023] The beneficial effects of this utility model are: it enables efficient assembly and disassembly of the beauty device and replacement of the roller head, enhancing device performance; it ensures stable assembly between accessories; the automatic rotation of the roller head improves automation and enhances user experience; it improves the stability and sealing of accessory assembly; it ensures stable assembly and operation of electrical accessories and facilitates portability; it ensures stable contact, conduction, and lighting, enhancing user experience; it enables flexible replacement of the roller head and provides a cooling effect to the beauty device; and it enables deep massage with the beauty device.
