DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0025] Referring to Figures 1-4 , the embodiment provides an electric massage comb, which comprises: a main body 1, massage comb teeth 2, a control circuit board 3, a vibration module 4 and a tactile force sensing structure 5. The main body 1 comprises a one-piece comb handle 11 and a comb body 12. The tactile force sensing structure 5 comprises: a sensor module plate 51, a force sensor 52, a force conduction plate 53 and a connecting arm 54. The control circuit board 3 is arranged in the comb handle 11, and the vibration module 4, the sensor module plate 51, the force sensor 52, the force conduction plate 53 and the connecting arm 54 are all arranged in the comb body 12. The sensor module plate 51 and the vibration module 4 are electrically connected with the control circuit board 3. The end of the massage comb teeth 2 is connected with the outer surface of the comb body 12. The force conduction plate 53 is located below the massage comb teeth 2. The bottom of the connecting arm 54 is suspended, one end of the connecting arm 54 is connected with the sensor module plate 51, and the other end is connected with the force conduction plate 53. The force sensor 52 is fixed to the connecting arm 54, and the force sensor 52 is connected with the sensor module plate 51.

[0026] In the embodiment, when the user massages the scalp with the electric massage comb, the tactile force received by the massage comb teeth 2 is conducted to the force conduction plate 53 through the comb body 12, then to the connecting arm 54, and then to the force sensor 52 through the connecting arm 54, thereby triggering the micro deformation of the force sensor 52. The force sensor 52 detects the pressing force applied by the user by sensing the deformation of itself, and transmits the detection signal to the sensor module plate 51. The sensor module plate 51 is a PCB plate, which transmits the control signal to the control circuit board 3 after receiving the control signal. The control circuit board 3 controls the vibration module 4 to work by vibration for massage. The greater the pressing force applied by the user, the greater the micro deformation of the force sensor 52, and the different detection signals transmitted, thereby the control circuit board 3 can adjust the vibration frequency of the vibration module 4 according to the pressing force applied by the user, and thereby adjust the massage intensity, that is, the greater the pressing force applied by the user, the more intense the vibration, and the greater the massage intensity, thereby the user can quickly adjust the massage intensity according to his own needs, and the massage intensity can better match the user's needs, which can improve the user's experience. In addition, the bottom of the connecting arm 54 is suspended, which can form a deformation avoidance space below the connecting arm 54, and the connecting arm 54 is more prone to deformation, and accordingly, the force sensor 52 is also more prone to micro deformation, thereby improving the sensitivity of the force sensor 52.

[0027] Further, the main body 1 is a shell composed of an upper shell and a lower shell, and the control circuit board 3, the vibration module 4, and the tactile force sensing structure 5 are arranged between the upper shell and the lower shell.

[0028] Further, the width of the connecting arm 54 is smaller than the width of the sensor module plate 51 and the force conduction plate 53, so that the two sides of the force conduction plate 53 form air slots 55, and the air slots 55 are located between the sensor module plate 51 and the force conduction plate 53, thereby forming a deformation avoidance space, and facilitating the deformation of the connecting arm 54 and the force sensor 52.

[0029] Further, a fixed table 56 is arranged below the sensor module plate 51, and the sensor module plate 51 is installed on the fixed table 56; a cantilever pad 57 is arranged below the force conduction plate 53, the top surface of the fixed table 56 is flush with the top surface of the cantilever pad 57, and one end of the force conduction plate 53 away from the connecting arm 54 is fixed on the cantilever pad 57. The fixed table 56 can make the bottom of the connecting arm 54 suspended, facilitating the deformation of the connecting arm 54, and the cantilever pad 57 can make the force conduction plate 53 maintain a horizontal state, so that the force conduction plate 53 is more stable.

[0030] Further, a pad 6 is arranged between the massage comb teeth 2 and the force conduction plate 53, and the pad 6 is made of silica gel material.

[0031] Specifically, the upper surface of the pad 6 is an arc surface matched with the outer surface of the comb body 12, the lower surface is a plane matched with the conductive plate, and the lower surface of the pad 6 is attached to the upper surface of the force conductive plate 53. In the product, the massage comb teeth 2 will spread to both sides with the arc surface as the center, and the tactile force received by the massage comb teeth 2 will be first conducted to the pad 6 through the upper surface of the comb body 12, and then transmitted to the force conductive plate 53 through the pad 6; the upper surface of the pad 6 is set as an arc surface, which can collect the pressing force conducted by each massage comb tooth 2 in all directions, and uniformly and concentratedly conduct the pressing force to the force conductive plate 53, avoiding the pressing force of the massage comb tooth 2 at the edge from being not sensed, so as to improve the sensitivity of the force sensor 52 triggering.

[0032] Further, the vibration module 4 comprises a vibration motor 41 and a vibration conductive plate 42, the vibration conductive plate 42 is fixed in the comb body 12; the vibration motor 41 is fixed on the vibration conductive plate 42 and is electrically connected with the control circuit board 3; the fixed table 56 and the cantilever pad 57 away from the massage comb tooth 2 are fixed on the vibration conductive plate 42. The fixed table 56 can support and fix the connecting arm 54 and the sensor module plate 51 on the vibration conductive plate 42. When the vibration motor 41 works, it will drive the vibration conductive plate 42 to vibrate, and then drive the whole comb body 12 to vibrate through the vibration conductive plate 42, and massage through the massage comb tooth 2. The rotating speed of the vibration motor 41 is controlled by the control circuit board 3, the greater the rotating speed, the more intense the vibration, and the greater the massage strength.

[0033] Further, the comb handle 11 is also provided with a battery 7, which is electrically connected with the control circuit board 3 and supplies power for the whole electric massage comb.

[0034] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
