Description

Technical Field

[0001] This application relates to the field of massage device technology, and in particular to an improved lightweight massage device. Background Technology

[0002] In recent years, with the increasing demand for health management among consumers, massage devices have gradually become a hot product in the market. Currently, most massage devices on the market use a motor-driven transmission mechanism, transmitting power to the massage head through rigid connecting parts (such as connecting rods and swing arms) to achieve massage actions such as kneading and pounding. However, existing technologies generally use a solid, one-piece structure design for the connecting parts. While this ensures mechanical strength, it results in a relatively large overall weight. This design flaw causes two problems: firstly, the excessive weight of the connecting parts increases the motor load, leading to a significant increase in motor power consumption and severely limiting the product's battery life; secondly, the weight of the entire device is concentrated in the transmission components, which can easily cause user fatigue with prolonged use, affecting the user experience.

[0003] Some manufacturers have attempted to reduce weight by using lightweight alloy materials or reducing the size of connectors, but such solutions have obvious limitations: lightweight alloys are expensive, which is not conducive to the commercialization of products; while reducing the size of connectors will reduce structural strength, which can easily lead to a decrease in the stability of the transmission system, and even cause the amplitude of the massage head to decrease, affecting the massage effect.

[0004] Therefore, there is an urgent need for an innovative design scheme that can achieve lightweight structure and reduce motor energy consumption while ensuring the mechanical performance and transmission efficiency of the connectors, so as to break through the current technical bottleneck of massager products. Utility Model Content

[0005] This application provides an improved lightweight massager to at least solve the technical problems of large weight and short battery life of massagers in the related art.

[0006] To achieve the above objectives, this application provides an improved lightweight massager, including a main unit and a movable massage head mounted on the main unit. The main unit is equipped with a drive motor and a transmission mechanism, and the transmission mechanism is connected to the drive motor. The massage head is connected to the transmission mechanism via a connector. The drive motor drives the massage head to reciprocate relative to the main unit via the transmission mechanism. The connector has a weight-reducing groove formed on it to reduce its weight.

[0007] In some embodiments, the connector includes a connecting portion connected to the transmission mechanism and a connecting rod extending from the connecting portion, the end of the connecting rod having a connecting end that engages with the massage head.

[0008] In some embodiments, the weight-reducing groove is formed non-through on the connecting rod and extends from the connecting portion to the connecting end.

[0009] In some embodiments, the weight-reducing grooves are symmetrically arranged on both sides of the connecting rod.

[0010] In some embodiments, the connector extends at least two connecting rods from the connecting portion.

[0011] In some embodiments, the connecting rods extend circumferentially from the connecting portion and are equidistantly distributed along the circumferential direction of the connecting portion.

[0012] In some embodiments, one end of the connecting rod near the connecting portion has an arc-shaped structure that bends toward the connecting portion, while the other end extends away from the host.

[0013] In some embodiments, the number of connecting rods is set to an even number, and two opposite connecting rods form an arc-shaped or U-shaped structure.

[0014] In some embodiments, the connecting rod is connected to the middle section of the connecting portion in the circumferential direction or to the end section away from the host, and the connecting portion has a buffer end formed at the end closer to the host.

[0015] In some embodiments, the weight-reducing grooves are located on both sides of the connecting rod in the non-bending direction.

[0016] Based on the above, the beneficial effects of the technical solution in this application are:

[0017] 1. By opening weight-reducing grooves on both sides of the connecting rod of the connector, the weight of the connector can be reduced by about 30% without changing the original strength of the connector, thereby effectively increasing the battery life of the massager;

[0018] 2. The arched or U-shaped structure of the connecting rod, in conjunction with the buffer end on the connecting part, can effectively prevent the connecting rod from colliding with the main unit during reciprocating motion, thereby reducing equipment noise. Attached Figure Description

[0029] This application provides an improved lightweight massager, including a main unit and a movable massage head mounted on the main unit. The main unit is equipped with a drive motor and a transmission mechanism. The transmission mechanism is connected to the drive motor. The massage head is connected to the transmission mechanism through a connector. The drive motor drives the massage head to reciprocate relative to the main unit through the transmission mechanism. The connector has a weight-reducing groove to reduce the weight of the connector.

[0030] Implementation, for example Figures 1-5 As shown, an improved lightweight massager includes a main unit 1 and a movable massage head 2 mounted on the main unit 1. The main unit 1 is equipped with a drive motor and a transmission mechanism, which are connected to the drive motor. The massage head 2 is connected to the transmission mechanism via a connector 3. The drive motor drives the massage head 2 to reciprocate relative to the main unit 1 through the transmission mechanism.

[0031] Specifically, the transmission mechanism includes transmission gears, transmission rods, eccentric wheels, and other structures that work together to achieve the effect of reciprocating motion of the massage head 2 relative to the main unit 1 under the drive of the drive motor. This transmission mechanism can be implemented using existing technology and is not the subject of this application; therefore, it is not shown in the accompanying drawings.

[0032] Furthermore, the connector 3 includes a connecting portion 3.1 connected to the transmission mechanism and a connecting rod 3.2 extending circumferentially from the connecting portion 3.1, with a connecting end 3.3 formed at the end of the connecting rod 3.2 that mates with the massage head 2.

[0033] Furthermore, at least two connecting rods 3.2 extend from the connecting portion 3.1 and are equidistantly distributed along the circumference of the connecting portion 3.1. One end of the connecting rod 3.2 near the connecting portion 3.1 has an arc-shaped structure that bends toward the connecting portion 3.1, and the other end extends away from the main unit 1 and connects to the massage head 2.

[0034] Specifically, the number of connecting rods 3.2 is set to an even number, and two opposite connecting rods 3.2 form an arc-shaped or U-shaped structure to ensure the overall structural strength of the connector 3. In this embodiment, the number of connecting rods 3.2 is set to two.

[0035] Furthermore, a weight-reducing groove 3.4 is formed on the connecting rod 3.2 to reduce the weight of the connector 3. The weight-reducing groove 3.4 extends from the connecting part 3.1 to the connecting end 3.3. In order to ensure the structural strength of the connector 3, the weight-reducing groove 3.4 is formed on the connecting rod 3.2 in a non-through manner.

[0036] Specifically, to ensure the structural strength of connector 3, weight-reducing grooves 3.4 are provided on the non-bending direction of connecting rod 3.2. To further reduce the weight of connector 3, weight-reducing grooves 3.4 are symmetrically provided on both sides of the non-bending direction of connecting rod 3.2.

[0037] Furthermore, a silicone ring 4 is installed at the connection between the connector 3 and the main unit 1 to reduce the collision between the connector 3 and the main unit 1 when the massage head 2 is reciprocating, thereby reducing noise.

[0038] Furthermore, the connecting rod 3.2 is connected to the middle section of the connecting part 3.1 in the circumferential direction or the end section away from the host 1. The connecting part 3.1 has a buffer end 3.5 at the end near the host 1. The buffer end 3.5 can provide buffer space for the connecting rod 3.2 when the connecting part 3 is close to the host 1, so as to prevent the connecting rod 3.2 extending from the connecting part 3.1 in the circumferential direction from directly colliding with the host 1.

[0039] Furthermore, the massage head 2 is made of lightweight materials such as silicone or sponge, further reducing the overall weight of the massager.

[0040] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
