Description

Technical Field

[0001] This invention relates to the field of massage technology, specifically to a head massager. Background Technology

[0002] With the fast pace of life and work, people are often prone to excessive brain fatigue and tension due to high-frequency work, leading to poor blood circulation in the brain. At this time, they will use various types of massage devices for auxiliary massage, which can soothe nerves, promote blood circulation, enhance cell metabolism, improve skin elasticity, relieve fatigue, relax the body, and reduce stress. However, most of the head massagers commonly used on the market currently use O-rings for sealing, resulting in an excessive gap between the massage head and the shell. During operation, unstable sealing can easily lead to contamination of the internal components of the massager, thus causing damage to the head massager. Utility Model Content

[0003] This invention addresses the aforementioned problems by proposing a head massager that features a stable seal, preventing contamination of the internal components and increasing the lifespan of the head massager.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, a drive motor, a transmission device, a rocking arm, and a massage device. The drive motor has an output rod, which is rotatably connected to the transmission device. The rocking arm is interference-fitted to the transmission device and drives the massage device to move accordingly. The transmission device includes a first drive group and a second drive group symmetrically arranged on both sides of the drive motor. The first drive group has a first transmission gear and a second transmission gear. The first transmission gear is rotatably connected to the output rod. The second transmission gear is located on one side of the first transmission gear and meshes with it. Symmetrically arranged on both sides of the second transmission gear are first drive gears and second drive gears meshing with it. The massage device includes a waterproof sleeve and an acupoint massage head. The housing has a mounting hole facing the acupoint massage head. The waterproof sleeve passes through the mounting hole and is inserted into the acupoint massage head. The rocking arm passes through the first drive gear and the waterproof sleeve in sequence and is inserted into the acupoint massage head, forming a rotatable connection with it.

[0005] By adopting the above technical solution, when the drive motor is working, it drives the output rod to rotate. The output rod transmits power to the first transmission gear, thereby driving the meshing motion of the second transmission gear and the first drive gear. The rocker arm passes through the first drive gear and the waterproof sleeve and is inserted into the acupoint massage head. This forms a situation where the first drive gear works with the rocker arm to drive the waterproof sleeve and the acupoint massage head to rotate together. Unlike head massagers that use O-rings for sealing, the waterproof sleeve can protect the device and prevent the internal components of the massager from becoming contaminated due to unstable sealing during operation, thus avoiding damage to the head massager.

[0006] The present invention is further configured such that the waterproof sleeve is sequentially provided with an L-shaped step, a first U-shaped sleeve, a second U-shaped sleeve, and a third U-shaped sleeve; the acupoint massage head has an internal mounting groove; the third U-shaped sleeve has its opening facing the mounting through hole and is embedded in the mounting groove; the second U-shaped sleeve has its opening facing the acupoint massage head and one end is connected to the third U-shaped sleeve; the first U-shaped sleeve has its opening facing the housing; the two sides of the first U-shaped sleeve are respectively connected to the second U-shaped sleeve and the L-shaped step; and the L-shaped step is securely mounted on the mounting through hole.

[0007] Through the above technical solution, the waterproof sleeve allows the entire transmission device to operate in a dry environment, providing good protection and isolation. The L-shaped step passes through the mounting hole and is clamped onto the housing, forming a stable connection between the waterproof sleeve and the housing. The first U-shaped sleeve and the second U-shaped sleeve can make way for the acupoint massage head when working together, avoiding structural interference.

[0008] The present invention is further configured such that a T-shaped protective sleeve is clamped inside the third U-shaped sleeve, the T-shaped protective sleeve is interference-fitted onto the rocker arm, and one end is pressed against the third U-shaped sleeve.

[0009] By adopting the above technical solution, the T-shaped protective sleeve can provide flexible contact between the rocker arm and the third U-shaped sleeve, thereby improving the compatibility between the rocker arm and the third U-shaped sleeve.

[0010] The present invention is further configured such that a snap-fit ​​assembly is abutting one side of the L-shaped step, the snap-fit ​​assembly including a snap-fit ​​sleeve and a fixing seat, the snap-fit ​​sleeve having a positioning groove for installing the fixing seat, the fixing seat being inserted into the positioning groove, the fixing seat having a first arc-shaped groove on its inner circumferential surface, the snap-fit ​​sleeve having a second arc-shaped groove communicating with the positioning groove, and a fixing ball being provided on the rocker arm, the outer circumferential surface of the fixing ball abutting against the first arc-shaped groove and the second arc-shaped groove.

[0011] By adopting the above technical solution, the first arc groove and the second arc groove can fit against the outer circumference of the fixed ball, thereby limiting the trajectory of the fixed ball.

[0012] The present invention is further configured such that the snap-fit ​​sleeve is provided with a positioning panel, the positioning panel is provided with a boss protruding on the side near the housing, the outer peripheral surface of the boss extends in a ring array towards the L-shaped step and is provided with a fixed support foot, the housing is provided with a positioning baffle that is locked with the fixed support foot, and the fixed support foot is inserted and fixedly connected to the positioning baffle.

[0013] By adopting the above technical solution, the fixed support feet and the positioning baffle are locked together, which can play a role in supporting and positioning the waterproof rubber sleeve on the shell, thus avoiding the problem of position displacement during operation.

[0014] The present invention is further configured such that a plurality of insertion interfaces are provided on the outer peripheral surface of the fixed base, and a snap-fit ​​part adapted to the insertion interface is provided on the inner peripheral surface of the positioning groove facing the outer peripheral surface of the fixed base, and the snap-fit ​​part is snapped into the insertion interface.

[0015] By adopting the above technical solution, the locking part and the plug interface can be used to lock the fixed seat tightly inside the locking sleeve, thereby achieving the effect of supporting and positioning the rocker arm.

[0016] The present invention is further configured such that an eccentric hole is provided on the first drive gear, and an eccentric shaft is inserted into the fixed ball. The eccentric shaft passes through the eccentric hole and the fixed ball in sequence and is inserted into the T-shaped protective sleeve.

[0017] By adopting the above technical solution, the eccentric shaft can work with the rocker arm to drive the massage head to form a stable axial movement along the working trajectory. Attached Figure Description
