Detailed Implementation
[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.
[0024] Please see Figure 1-5This utility model provides an abdominal massager, including a housing 1, with belts 10 that can be connected to each other fixedly installed at both ends of the housing 1;
[0025] It also includes a drive device 2, which includes a motor 20 fixedly installed in the housing 1 and a screw 21 installed at one end of the motor 20;
[0026] The massage device 3 includes a drive shaft 30 rotatably disposed in the housing 1, an eccentric device 31 disposed at the end of the drive shaft 30, a massage head 32 fixedly disposed at one end of the eccentric device 31, a first helical gear 33 sleeved on the drive shaft 30, and a gear set 34 connecting the first helical gear 33 and the screw 21.
[0027] In the above structure, the motor drives the screw to rotate, the gear set transmits power to the drive shaft, the rotation of the drive shaft drives the eccentric device to rotate, thereby moving the massage head. By using the drive shaft, helical gear and gear set as an integrated structure, the transmission structure is simpler and occupies less space, while the transmission effect is better.
[0028] Specifically, bearings 300 are sleeved at both ends of the drive shaft 30. Using bearings can reduce friction and wear of the drive shaft during rotation, thereby extending the service life of the drive shaft. At the same time, the reduction of the coefficient of friction helps to reduce energy loss and improve mechanical efficiency.
[0029] Specifically, the massage head 32 is provided with multiple protrusions 320 at intervals. The protrusions on the massage head can form a clear point of force, thereby providing a more precise stimulation effect on the acupoints of the human body.
[0030] Specifically, the gear set 34 includes a first rotating shaft 340 rotatably disposed inside the housing 1, a first gear 341 and a second gear 342 fixedly disposed on the first rotating shaft 340, a second rotating shaft sleeve 343 sleeved on the transmission shaft 30, a second rotating shaft 344 rotatably disposed on the second rotating shaft sleeve 343, and a second helical gear 345 and a third gear 346 fixedly disposed on the second rotating shaft 344. The first gear 341 meshes with the screw 21, the second gear 342 meshes with the third gear 346, and the second helical gear 345... When the motor drives the screw to rotate, the first gear meshing with the screw rotates synchronously with the first gear meshing with the screw. The first gear drives the first rotating shaft to rotate synchronously. The second gear fixed on the first rotating shaft rotates and drives the third gear meshing with the second gear to rotate. The third gear is fixed on the second rotating shaft and rotates synchronously with the second rotating shaft. The rotation of the second rotating shaft drives the second helical gear fixed on it to rotate. The second helical gear drives the first helical gear meshing with it to rotate. The first helical gear drives the transmission shaft to rotate synchronously. The use of gear meshing transmission can withstand a large load, and at the same time, the structure is compact and occupies little space.
[0031] Specifically, the housing 1 is equipped with a mugwort heating module, which heats the mugwort so that its active ingredients can better penetrate the skin and act on the human body.
[0032] Specifically, the eccentric device 31 includes a fixing part 310 sleeved on the transmission shaft 30, an eccentric body 311 disposed on the fixing part, and limiting parts 312 protruding on both sides of the eccentric body 311. The massage head 32 is sleeved on the eccentric body 311. The inclined surface of the eccentric body 311 forms an angle α with the transmission shaft 30. The angle α is 105°±10°. When the eccentric body is driven to rotate by the transmission shaft, it generates a certain amplitude of reciprocating motion, which causes the massage head sleeved on it to generate high-frequency vibration. When the massage head acts on human muscles and acupoints, this vibration can effectively relieve muscle fatigue and promote blood circulation.
[0033] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
