[0008] Furthermore, the pressure sensor is locked to the fixed base shell by multiple second screws, and the pressure sensing top shell is provided with multiple notches to avoid the second screws.

[0009] Furthermore, the pressure sensor is flat and has a large U-shaped groove and a small U-shaped groove. The small U-shaped groove is located inside the large U-shaped groove and the open end of the small U-shaped groove faces the closed end of the large U-shaped groove. The two strain gauges of the pressure sensor are respectively located between the two sides of the large U-shaped groove and the two sides of the small U-shaped groove.

[0010] Furthermore, a locking block is fixedly provided on the inner top surface of the pressure sensing top shell. The locking block is locked and fixed in the small U-shaped groove of the pressure sensor by a third screw, so that a gap is formed between the pressure sensing top shell and the pressure sensor.

Detailed Implementation

[0022] The present invention will be further described below through specific embodiments.

[0023] like Figures 1 to 6 As shown, the pressure-sensitive massage vibrator of this utility model includes a pressure-sensitive top shell 1, a pressure sensor 2, a motor cover 3, a vibration motor 4, an eccentric block 5, and a fixed bottom shell 6. The fixed bottom shell 6 has an upwardly open cavity 61. The motor cover 3 is fixedly installed in the cavity 61 of the fixed bottom shell 6. The motor cover 3 and the fixed bottom shell 6 form a motor cavity 71 in the middle and a shaft hole 72 is formed on one side between them. The vibration motor 4 is located in the motor cavity 71, and the motor shaft of the vibration motor 4 passes through the shaft hole 72 and is fixedly installed with the eccentric block 5 located in the cavity 61. The pressure sensor 2 is fixedly installed at the upper opening of the fixed bottom shell 6. The pressure-sensitive top shell 1 is fixedly installed on the upper end of the pressure sensor 2 and covers the pressure sensor 2.

[0024] Preferably, the pressure sensor 2 is a dual half-bridge miniature weighing sensor.

[0025] The vibration motor 4 drives the eccentric block 5 to rotate, thereby causing the pressure-sensitive massage vibrator to vibrate accordingly, achieving a massage function and providing a certain relaxation effect. The motor cover 3 and the fixed bottom shell 6 facilitate the stable installation of the vibration motor 4 and ensure that the eccentric block 5 is surrounded within the cavity 61, guaranteeing smooth rotation of the eccentric block 5. The pressure-sensitive top shell 1 provides protection for the pressure sensor 2 and effectively transmits the load pressure it receives to the pressure sensor 2. With the pressure sensor 2, when the pressure-sensitive massage vibrator is installed in an area with load pressure, it can detect the pressure on the corresponding part of the human body in real time and feed the pressure signal back to the external massage control system. Under the control of the massage control system, the massage control system can adjust the rotation speed and rotation time of the vibration motor 4 in real time according to the received pressure signal, thereby automatically adjusting the massage intensity of the pressure-sensitive massage vibrator according to the magnitude of the load pressure, so that the pressure-sensitive massage vibrator has a pressure-sensitive massage function and can provide personalized service to users.

[0026] The cavity 61 also extends through one end of the fixed base shell 6, and a wiring hole 73 is formed on the other side between the motor cover 3 and the fixed base shell 6, so that the cable of the vibration motor 4 can pass through the wiring hole 73 and be connected to the power supply to complete the power supply operation.

[0027] Correspondingly, the motor cover 3 is provided with an upper motor groove 31 that opens downwards, and the bottom of the cavity 61 of the fixed base shell 6 is provided with a lower motor groove 62. The upper motor groove 31 and the lower motor groove 62 together form the motor cavity 71, which is adapted to the vibration motor 4, thereby facilitating the installation of the vibration motor 4 and effectively ensuring the stability during installation.

[0028] The motor cover 3 is locked and fixed to the fixed base shell 6 by a plurality of first screws, preferably four first screws.

[0029] The pressure sensor 2 is locked and fixed to the fixed base shell 6 by a plurality of second screws. Preferably, there are four second screws. The pressure sensing top shell 1 is provided with a plurality of notches 11 to avoid the second screws. In this way, after the pressure sensing top shell 1 is fixedly connected to the pressure sensor 2, the second screws can easily pass through the notches 11 on the pressure sensing top shell 1 to lock and fix the pressure sensor 2 to the fixed base shell 6.

[0030] Preferably, the pressure sensor 2 is flat and has a large U-shaped groove 21 and a small U-shaped groove 22. The small U-shaped groove 22 is located inside the large U-shaped groove 21, with its open end facing the closed end of the large U-shaped groove 21. Two strain gauges 23 of the pressure sensor 2 are respectively located between the two sides of the large U-shaped groove 21 and the two sides of the small U-shaped groove 22. Preferably, the strain gauges 23 are resistance strain gauges. In addition, a lock is fixedly provided on the inner top surface of the pressure sensing top shell 1. The locking block 12 is locked and fixed to the small U-shaped slot 22 of the pressure sensor 2 by the third screw, and a gap 8 is formed between the pressure sensing top shell 1 and the pressure sensor 2. In this way, when any position on the upper surface of the pressure sensing top shell 1 is subjected to pressure, the pressure can be effectively transmitted to the area in the small U-shaped slot 22 of the pressure sensor 2 and subjected to force. As a result, the pressure sensor 2 will send a resistance change at the area of ​​the two strain gauges 23 to realize the real-time detection of pressure.

[0031] In addition, both sides of the locking block 12 are fixed with downwardly extending locking blocks 13. The two locking blocks 13 are arranged in parallel and are both locked in the small U-shaped slot 22. In this way, the stability of the connection between the pressure sensing top shell 1 and the pressure sensor 2 can be further improved.

[0032] In addition, the outer surfaces of the fixed bottom shell 6 and the pressure-sensing top shell 1 are provided with noise reduction layers. Correspondingly, the noise reduction layers can be formed by covering with foam material to reduce massage noise.

[0033] Preferably, the length of the fixed bottom shell 6 and the pressure-sensing top shell 1 is no greater than 45mm, and the width of the fixed bottom shell 6 and the pressure-sensing top shell 1 is no greater than 35mm. That is, the length of the massage vibrator is no greater than 45mm and the width is no greater than 35mm, so that the size of the massage vibrator is appropriate for easy installation and use on the massage backpack.

[0034] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
