Description

A rhythmic vibrator with a larger amplitude Technical Field

[0001] This utility model relates to a vibrator, specifically a rhythmic vibrator with a larger amplitude. Background Technology

[0002] Currently, vibrators used for vibration massage include a miniature DC vibration motor and an eccentric block connected to the output shaft of the miniature DC vibration motor. However, existing vibrators generally have the problem that the eccentric block is too light. There is also a medium, such as a leather layer or a cloth layer, between the vibrator and the human body to cover the vibrator. Because the existing eccentric block is light, the amplitude it produces is small. For a relatively thin medium layer, the amplitude produced by the vibrator can still be transmitted to the human body. However, for a thicker medium layer, such as a sponge medium layer, or when the vibrator is far away from the human body, the small amplitude produced by the existing vibrator is not enough to be transmitted to the human body. Summary of the Invention

[0003] This utility model provides a rhythmic vibrator with a larger amplitude, the main purpose of which is to overcome the problem of the small amplitude of existing vibrators.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A rhythmic vibrator with a larger amplitude includes a housing, a dual-output-shaft vibration motor, and two eccentric blocks. The dual-output-shaft vibration motor and the two eccentric blocks are all located inside the housing. The two eccentric blocks are respectively connected to the dual output shafts of the dual-output-shaft vibration motor. The two eccentric blocks are of similar size, and the sum of the weights of the two eccentric blocks is at least more than half the weight of the dual-output-shaft vibration motor, and at most 2-3 times the weight of the dual-output-shaft vibration motor.

[0006] Furthermore, the combined weight of the two eccentric blocks is 70-90% of the weight of the dual-output-shaft vibration motor.

[0007] Furthermore, the housing includes an upper housing and a lower housing connected to each other. The upper housing has an upper receiving cavity, and the lower housing has a lower receiving cavity. After the upper housing and the lower housing are connected, the upper receiving cavity and the lower receiving cavity form a space for placing a dual-output shaft vibration motor and two eccentric blocks.

[0008] Furthermore, the upper receiving cavity includes an upper receiving cavity for the motor, an upper receiving cavity for the left eccentric block, and an upper receiving cavity for the right eccentric block. A left upper partition is provided between the upper receiving cavity for the motor and the upper receiving cavity for the left eccentric block, with a left upper groove at the bottom of the left upper partition. A right upper partition is provided between the upper receiving cavity for the motor and the upper receiving cavity for the right eccentric block, with a right upper groove at the bottom of the right upper partition. The lower receiving cavity includes a lower receiving cavity for the motor, a lower receiving cavity for the left eccentric block, and a lower receiving cavity for the right eccentric block. A left lower partition is provided between the lower receiving cavity for the motor and the lower receiving cavity for the left eccentric block, with a left lower groove at the top of the left lower partition. A right lower partition is provided between the lower receiving cavity for the motor and the lower receiving cavity for the right eccentric block, with a right lower groove at the top of the right lower partition.

[0009] Furthermore, the upper and lower housings are connected by multiple screws or by ultrasonic welding.

[0010] Furthermore, the bottom surface of the upper housing is provided with a first positioning strip, and the top surface of the lower housing is provided with a first positioning groove. The first positioning strip is located in the first positioning groove. The bottom surface of the upper housing is provided with an upper arc hole, and the top surface of the lower housing is provided with a lower arc hole. After the upper housing and the lower housing are connected, the upper arc hole and the lower arc hole form a first wire hole.

[0011] Furthermore, the bottom surface of the upper housing is provided with a second positioning groove, the top surface of the lower housing is provided with a second positioning strip, the second positioning strip is located in the second positioning groove, and the upper housing is provided with a second wire hole.

[0012] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages: The present invention redefines the weight ratio of the two eccentric blocks to the weight of the dual-output shaft vibration motor. Compared with the existing vibrators, the two eccentric blocks of the present invention are heavier, and the dual-output shaft vibration motor can generate a larger amplitude when driving the two eccentric blocks to vibrate. Especially when the vibrator is used in a thicker medium layer or when the vibrator is far away from the human body, the larger amplitude can still allow people to feel the regular vibration effect.

The upper housing 4 has an upper receiving cavity, and the lower housing 5 has a lower receiving cavity. After the upper housing 4 and the lower housing 5 are connected, the upper receiving cavity and the lower receiving cavity form a space for placing the dual-output shaft vibration motor 2 and two eccentric blocks 3. In this embodiment, the upper housing 4 and the lower housing 5 are connected by multiple screws or by ultrasonic welding.

[0024] Referring to Figures 1 to 3, the upper receiving cavity includes a motor upper receiving cavity 61, a left eccentric block upper receiving cavity 62, and a right eccentric block upper receiving cavity 63. A left upper partition 64 is provided between the motor upper receiving cavity 61 and the left eccentric block upper receiving cavity 62, and a left upper groove 65 is provided at the bottom of the left upper partition 64.

[0027] Referring to Figures 1 to 3, the design principle of this utility model is as follows: This utility model redefines the weight ratio of the two eccentric blocks 3 to the weight of the dual-output shaft vibration motor 2. Compared with existing vibrators, the two eccentric blocks 3 of this utility model are heavier. When the dual-output shaft vibration motor 2 drives the two eccentric blocks 3 to vibrate, it can produce a larger amplitude. Especially when the vibrator is used in a thicker medium layer or when the vibrator is far from the human body, the larger amplitude still allows people to feel a regular vibration effect. Example 2
