Abstract
Description
Technical Field
[0001] This utility model relates to a massage device, and more particularly to an improved structure of an abdominal massager. Background Technology
[0002] In existing massagers of the same type, the power supply inside the massager body is directly connected to the auxiliary massage electronics inside the massage wheel through conductive wires. In order to prevent the conductive wires from getting tangled when the massage wheel rotates, the usual practice is to connect a slip ring in the middle of the conductive wires. However, the existing slip rings are expensive, have a relatively thin wire diameter, are not suitable for transmitting high current, and have a short service life and are easily damaged during installation and use, since the conductive wires will still rotate at a certain angle.
[0003] These massagers are designed to be used with or without oil, and their front covers are currently designed to be open. If essential oil is applied to the cloth cover on the outside of the massage rollers or to the skin being massaged, the essential oil can easily seep into the inside of the massager, resulting in poor waterproofing and insufficient safety.
[0004] Existing massage rollers have a simple structure, with only a few massage heads designed on the roller. The massage effect is poor, and the rollers without cloth covers will cause skin to twitch if massaged without oil. Oil must be applied for massage every time it is used.
[0005] The existing cloth sleeves are prone to falling off when the massage rollers rotate, which can easily tear the skin. They lack protective devices and are not convenient to use. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide an improved structure for an abdominal massager, addressing the shortcomings of existing technologies.
[0007] To achieve the above objectives, the present invention adopts the following measures:

The drive motor is driven and connected to the massage wheel. An auxiliary massage electronic component is mounted on the massage wheel. The auxiliary massage electronic component is electrically connected to the battery and the circuit board through two conductive brushes. A conductive seat is provided in the rear end of the massage wheel. The conductive seat has conductive holes that pass through both sides.

The outer edge of the drive hole has a sealing step surface. A waterproof bearing is provided on the sealing step surface. The waterproof bearing is sleeved on the drive ring. A waterproof water seal ring is provided between the waterproof bearing and the sealing step surface.
[0010] The massage wheel is rotatably mounted with several massage rollers on its outer side, and the axis of the massage rollers is parallel to the surface of the massage wheel.
[0011] The massage roller has a vibration motor inside its roller shaft, and the vibration motor is electrically connected to the conductive brush.
[0012] The massage roller has massage ribs on its outer spiral.
[0013] The auxiliary massage electronic components mentioned above are vibration motors, heating elements, heating lamps, or ultrasonic transmitters;

[0015] A locking spring is provided between the latch and the front cover. The locking spring is sleeved on the guide post at the inner end of the latch. One end of the locking spring presses against the latch, and the other end presses against the front cover.
[0016] The front cover has an L-shaped opening groove on its front side, and the inner side of the fabric sleeve has an insert that mates with the L-shaped opening groove.
[0017] The positive and negative electrical connectors of the vibration motor extend from both ends of the massage roller, and the extended parts are electrically connected to the conductive brush through contact with the spring conductive post.

[0028] An improved structure for an abdominal massager includes a massager body 1. The outer shell of the massager body 1 is composed of a rear cover 101 and a front cover 102 fixed together. A battery, a circuit board, and a drive motor are electrically connected inside the massager body 1. A massage wheel 2 is rotatably mounted on the outer side of the front cover 102. The drive motor is driven and connected to the massage wheel 2. Auxiliary massage electronic components are mounted on the massage wheel 2. These auxiliary massage electronic components are electrically connected to the battery and the circuit board via two conductive brushes 3. The rear end of the massage wheel 2... The device has a conductive base 4 with conductive holes 401 extending through both sides. The conductive brush 3 is slidably disposed in the conductive holes 401. The massager body 1 has a conductive disk 5 that is electrically connected to the battery and the circuit board. After the conductive brush 3 passes through the conductive holes 401, one end slides and presses against the conductive ring 501 of the conductive disk 5, and the other end is provided with a spring 6. One end of the spring 6 presses against the conductive brush 3, and the other end is electrically connected to the contact of the auxiliary circuit board 100 in the massage wheel 2. The auxiliary massage electronic components are electrically connected to the auxiliary circuit board 100.
[0029] like Figure 1 and Figure 2 As shown, the massage roller 2 in this application can be an existing design structure as shown in the figure, or it can be an innovative one. Figure 2 The design structure within.
[0030] like Figure 3 As shown, in this application, the auxiliary massage electronic components within the massage wheel 2 are electrically connected to the battery and circuit board via two conductive brushes 3. Specifically, a conductive disk 5 is installed and fixed inside the massager body 1. Two conductive rings 501 are concentrically arranged on the conductive disk 5, and the two conductive rings 501 are electrically connected to the positive and negative terminals of the power supply (electrically connected to the battery and circuit board, respectively). Under the elastic force of the spring 6, one end of the conductive brush 3 is pressed tightly against the conductive ring 501. When the massage wheel 2 rotates, it drives the conductive brush 3 to rotate along the conductive ring 501. The conductive brush 3 thus conducts electricity to the auxiliary massage electronic components within the massage wheel 2 while the massage wheel 2 rotates. This design eliminates the need for traditional conductive wire connections, avoids tangling, and saves on production costs.
[0031] The massage wheel 2 has an integrally formed drive ring 201 on its rear side for driving its own rotation. The front cover 102 has a drive hole 103 for the drive ring 201 to pass through. After the drive ring 201 passes through the drive hole 103, a drive gear 7 is sleeved and fixed. The drive gear 7 is connected to the drive motor through a transmission gear set. The outer edge of the drive hole 103 has a sealing step surface 104. A waterproof bearing 8 is provided on the sealing step surface 104. The waterproof bearing 8 is sleeved on the drive ring 201. A waterproof water seal ring 9 is provided between the waterproof bearing 8 and the sealing step surface 104.
[0032] like Figure 4 and Figure 5 As shown, the front cover 102 in this application has only one drive hole 103 in the middle, which is the same size as the drive ring 201. This is a departure from the previous open design. A sealing step surface 104 is designed on the edge of the drive hole 103. The addition of a waterproof bearing 8 and a waterproof water seal ring 9 achieves a good sealing effect and effectively prevents water stains or essential oil from entering the machine.
[0033] A plurality of massage rollers 10 are rotatably mounted on the outer side of the massage wheel 2, and the axis of the massage rollers 10 is parallel to the surface of the massage wheel 2.
[0034] like Figure 6 and Figure 7 As shown, the previous massage roller 2 had a simple massage structure, only consisting of some... Figure 1 The massage ribs or massage balls shown in the original diagram have poor massage effect. In this application, by adding massage rollers 10, the axis of the massage rollers 10 is set parallel to the surface of the massage wheel 2, resulting in a better massage effect.
[0035] The massage roller 10 has a vibration motor 11 inside the roller shaft 1001, and the vibration motor 11 is electrically connected to the conductive brush 3.
[0036] The massage roller 10 has massage ribs on its outer spiral to enhance the massage effect.
[0037] The auxiliary massage electronic components include a vibration motor, a heating element, a heating lamp, or an ultrasonic transmitter, or other electronic components. The auxiliary massage electronic components are powered via two conductive brushes 3 with springs 6, which are electrically connected to the battery and circuit board through a conductive disk 5. The vibration motor vibrates, enhancing the massage effect. The heating element provides heat, similar to moxibustion massage; the heating lamp, if decorative, can also provide heat to improve the massage effect; and the ultrasonic transmitter provides ultrasonic massage.
[0038] The outer side of the front cover 102 is detachably rotatably connected to a cloth sleeve 12, and an elastic cloth sleeve for wrapping the massage wheel 2 is fixed inside the cloth sleeve 12. A locking groove 1201 is provided on the lower edge of the cloth sleeve 12, and a locking buckle 1202 is slidably provided inside the front cover 102.
[0039] A locking spring 1203 is provided between the latch 1202 and the front cover 102. The locking spring 1203 is sleeved on the guide post at the inner end of the latch 1202. One end of the locking spring 1203 presses against the latch 1202, and the other end presses against the front cover 102.
[0040] like Figure 8 and Figure 9As shown, this application solution adds a locking groove 1201 and a component locking buckle 1202. After the fabric loop 12 is rotated and fixed on the front cover 102, the locking buckle 1202, under the elastic force of the locking spring 1203, falls into the locking groove 1201, preventing the fabric loop 12 from rotating and falling off. When it is necessary to remove the fabric loop 12, simply overcome the elastic force of the locking spring 1203, push the locking buckle 1202 out of the locking groove 1201, and then rotate the fabric loop 12 in the opposite direction to remove it.
[0041] The front cover 102 has an L-shaped opening groove 109 on its front side, and the inner side of the fabric sleeve 12 has an insert 1204 that mates with the L-shaped opening groove 109. This connection structure is the same as the existing structure design on the fabric sleeve 12.
[0042] The positive and negative electrical connectors 1101 of the vibration motor 11 extend from both ends of the massage roller 10, and the extended parts are electrically connected to the conductive brush 3 through contact with the spring conductive post 1102.
