[0079] Example 1, when the comb tooth base adopts massage comb teeth:
[0080] The comb tooth base is a liquid guide comb tooth 5. The liquid guide comb tooth 5 includes a seat body 51 and a hollow second comb tooth 52. The seat body 51 is provided with a liquid inlet. The inner cavity of the seat body 51 is a liquid distribution cavity. The liquid inlet is communicated with the liquid distribution cavity.

[0083] The liquid guiding comb teeth 5 are detachably arranged in the installation cavity, and the push rod 42 extends towards the piston direction.
[0084] When the liquid guiding comb teeth 5 are installed:
[0085] The control circuit board switches to the liquid pushing mode according to the signal (disconnection signal) of the Hall element.
[0086] Start the liquid pushing device (the driving assembly 41 and the push rod 42), and prepare to push the liquid when the distance sensing device 33 detects approaching the scalp.
[0087] The distance sensing device 33 is an infrared sensing device, and the working principle of the infrared sensing device is as follows:
[0088] The infrared sensing device has an infrared emitter built-in, usually an infrared LED diode. When the device works, the infrared LED emits invisible infrared light.
[0089] When the infrared light encounters an obstacle (such as the scalp), it will be reflected. The reflected infrared light will be reflected back to the sensing device.
[0090] The infrared receiver (such as an infrared receiving diode or an infrared phototransistor) built into the infrared sensing device is responsible for receiving the reflected infrared light. The receiver converts the received infrared light signal into an electrical signal.
[0091] The signal processing circuit in the infrared sensing device processes the received electrical signal. By measuring the intensity and time difference of the reflected infrared light, the presence and distance of the obstacle can be calculated.
[0092] According to the processed signal, the infrared sensing device outputs a corresponding electrical signal to the control circuit board or other control circuits. The control circuit board judges whether the comb teeth part 311 is close to the scalp according to this signal, so as to control the start and stop of the driving assembly 41.
[0093] Using the infrared sensing device as the distance sensing device 33, the beneficial effects include:
[0094] The infrared sensing device can accurately detect the distance between the comb teeth part 311 and the scalp, ensuring that the driving assembly 41 starts or stops at the correct time.
[0095] Through the real-time detection of the infrared induction device, the main control board can automatically control the start and stop of the driving component 41, avoiding the errors of manual operation and improving the intelligence and convenience of use.
[0096] The infrared induction device will trigger the activation of the driving component 41 only when it detects that the comb teeth part 311 is close to the scalp, effectively reducing unnecessary energy consumption and prolonging the service life of the battery.
[0097] The infrared induction device ensures that the driving component 41 works only when it is close to the scalp, reducing the operation steps of the user, enhancing the comfort and convenience of use, and enabling the user to focus more on enjoying the process of scalp massage and care.

[0105] When the massage comb tooth 8 is installed:
[0106] The control circuit board switches to the massage mode according to the signal (switch-on signal) of the Hall element.
[0107] Start the vibration motor to provide the user with a vibration massage function.
[0108] In the above-mentioned Embodiment 1 and Embodiment 2, the user can easily switch between the liquid guide comb teeth 5 and the massage comb teeth 8 of the hair growth comb. The intelligent detection of the Hall element and the automatic identification and switching function of the control circuit board make this process simple and fast, and ensure the normal operation of each function mode.
[0109] When installing the liquid guide comb teeth 5, start the liquid pushing device (the driving component 41 and the push rod 42), and prepare to push the liquid when the proximity sensing device 33 detects approaching the scalp.
[0110] When installing the massage comb teeth 8, the vibration motor will keep working, and the infrared sensing device no longer controls its start and stop, so as to provide a continuous massage effect.
