[0029] As Figure 1 shown, this embodiment discloses a massager, which includes a main body 1, a holding part 2 and a massage head 3. When a user uses the massager, the user can tightly hold the holding part 2 of the massager with the hand and place the massager on the part to be massaged. To ensure that the user can firmly hold the massager and prevent it from falling during vibration massage, a tightening component 7 is installed on the holding part 2. In this embodiment, the tightening component 7 is a ratchet tightener. Pulling rings are arranged on both sides of the holding part 2, and the tightening belt passes through the two pulling rings and is installed on the ratchet tightener. After the user tightly holds the holding part 2 with the palm, the tightening belt is tightened so that the palm firmly holds the massager, and then the ratchet tightener is used to fasten the pull handle to fix the tightening belt, so that the user will not drop the massager due to vibration, rotation and other reasons during use.

[0030] As Figures 2-3 shown, a circuit board 4, a DC motor 5, a driving gear 101 and a rotating rod 6 are installed in the main body 1 of the massager. The circuit board 4 is electrically connected to the DC motor 5. The driving gear 101 is sleeved on the rotating shaft of the DC motor 5. The massage head 3 is installed at the end of the rotating rod 6, and a rotating gear 105 is installed in front of the rotating rod 6. The massager drives the rotating rod 6 to rotate by gear transmission, thereby driving the massage head 3 to operate. In this embodiment, the massager adopts gear reduction transmission. A number of gears are provided in the main body 1 of the massager for reduction transmission, including a first transmission gear 102, a second transmission gear 103 and a third transmission gear 104. The first transmission gear 102, the second transmission gear 103 and the third transmission gear 104 are respectively gear sets composed of a large gear 106 and a small gear 107 rotating along the same axis. The large gear 106 of the first transmission gear 102 meshes with the driving gear 101. The large gear 106 of the second transmission gear 103 meshes with the small gear 107 of the first transmission gear 102. The large gear 106 of the third transmission gear 104 meshes with the small gear 107 of the second transmission gear 103. The rotating gear 105 meshes with the small gear 107 of the third transmission gear 104. This embodiment adopts four-stage gear reduction transmission. Of course, two-stage or three-stage gear reduction transmission can also achieve the same gear transmission effect. Through experimental tests on the influence of gear wear, transmission stability, gear size, etc., four-stage gear reduction transmission is adopted in the embodiment.

[0031] As Figures 4-6As shown in the figure, the massage head 3 includes a fixing sleeve 301, a roller 302 and a colloidal body 304. The fixing sleeve 301 is buckled and fixed to the rotating rod 6. A rib 305 is provided on the inner wall of the fixing sleeve 301, and a circumferential groove 601 is opened at the end of the rotating rod 6. The rib 305 is buckled into the groove 601 for fixation. In this embodiment, the end of the rotating rod 6 is designed as a hexagon for stable fixation. Of course, other geometric shapes can also be used, such as triangles, squares, regular pentagons, etc. The fixing sleeve 301 is provided with fixing shafts 303 radially scattered from the center. The roller 302 is sleeved on the fixing shaft 303 and can rotate around the fixing shaft 303. A colloidal body 304 is sleeved on the roller 302.

The colloidal body 304 can be designed in various styles to massage the body part, such as a cone with a round head. In this embodiment, the fixing sleeve 301 is designed as a hexagon, and theoretically, six fixing shafts 303 can be provided. However, due to the size of the roller 302 in this embodiment, three fixing shafts 303 are provided. But by reducing the size of the roller 302 so that the rollers 302 do not interfere with each other, six fixing shafts 303 can also be provided.

The source of the MOS transistor Q2 is connected to the resistor R10 and then connected to the circuit ground. One end of the resistor R8 is connected to the gate of the MOS transistor Q2 and the other end is connected to the circuit ground. At the same time, a path is led out from the source of the MOS transistor Q2 to the control chip to provide a feedback signal for the control chip. When starting, the control chip sends a high level to the gate of the MOS transistor Q2, the MOS transistor Q2 is turned on, the DC motor 5 is powered on and operates, and at the same time, a feedback signal is sent back from the source of the MOS transistor Q2 to the control chip U2.

[0034] In this embodiment, the USB charging is completed by the charging chip U1. The control chip U2 is signal-connected to the charging chip U1 through the charging circuit 9 to control the charging chip U1 to be powered on and operate. The charging circuit 9 includes an MOS transistor Q1, a triode Q3, and resistors R9 and R12. The drain of the MOS transistor Q1 is connected to the power supply terminal of the USB interface. The source of the MOS transistor Q1 is connected to the power supply pin of the charging chip U1. The gate of the MOS transistor Q1 is connected to the collector of the triode Q3.
