[0044] In this embodiment, the power supply assembly 40 includes a battery and a battery box. In other embodiments, the power supply assembly 40 can also be a power adapter. Or, the power supply assembly 40 includes a battery and also includes a power supply cavity cover (not shown). The power supply cavity cover is hermetically covered in the power supply cavity 33, and the battery is directly arranged in the power supply cavity 33.

[0045] In this embodiment, the induction module 50 can be one of a capacitance sensor, a microwave sensor, an ultrasonic sensor, and an infrared sensor.

[0046] In an example, such as Figure 5 and Figure 6As shown, a linear first guiding groove 34 and a vertically retractable first elastic buckle 35 are formed on the inner wall of the power supply cavity 33, and a linear guiding rib 41 and a protruding first fixing buckle 42 are arranged on the outer wall of the power supply assembly 40. During the process of inserting the power supply assembly 40 into the power supply cavity 33 from the front end of the rear shell 30, the guiding rib 41 can cooperate with the first guiding groove 34 to guide the power supply assembly 40 into the power supply cavity 33. When the power supply assembly 40 is inserted in place, the first elastic buckle 35 is snapped with the first fixing buckle 42. In other examples, a linear first guiding groove and a vertically retractable first elastic buckle can be formed on the outer wall of the power supply assembly 40, and a linear guiding rib and a protruding first fixing buckle are arranged on the inner wall of the power supply cavity 33.

[0047] In one example, referring to Figure 5 and Figure 7 , a linear second guiding groove 37 is formed on the inner wall of the induction module cavity 36, and a guiding block 51 is arranged on the outer wall of the induction module 50. The guiding block 51 can be a linear rib. During the process of inserting the induction module 50 into the induction module cavity 36 from the front end of the rear shell 30, the guiding block 51 can cooperate with the second guiding groove 37 to guide the induction module 50 into the induction module cavity 36.

[0048] In another example, a linear second guiding groove 37 is formed on the outer wall of the induction module 50, and a linear guiding block 51 is arranged on the inner wall of the induction module cavity 36.

[0049] In another example, the power supply assembly 40 can also be magnetically connected in the power supply cavity 33.

[0050] Referring to Figures 1 to 10 , in addition to the fixing bracket 20 and the rear shell 30, the nozzle assembly further includes a face cover 70 covering the opening of the accommodating cavity. A nozzle opening 73 corresponding to the position of the nozzle 32 is formed on the face cover 70. The nozzle opening 73 faces downward, and the water sprayed from the nozzle opening 73 can wash the face 12 clean.

[0051] In one example, the face cover 70 can be detachably connected to the rear shell 30 by snap connection. As Figure 4 shown, a second elastic buckle 71 is arranged on the inner peripheral edge of the face cover 70, and a second fixing buckle 38 is arranged on the front peripheral edge of the rear shell 30. When the face cover 70 is pressed against the rear shell 30 in place, the second elastic buckle 71 can be snapped with the second fixing buckle 38. For another example, a second elastic buckle 71 is arranged on the front peripheral edge of the rear shell 30, and a second fixing buckle 38 is arranged on the inner peripheral edge of the face cover 70.

The end of the elastic member 63 is connected to the end of the sensing module cavity 36, and the front end of the elastic member 63 is connected to the top block 62. The sensing module 50 is arranged between the top block 62 and the surface cover 70. Such a structure enables the elastic member 63 to provide a forward force for the top block 62, so that the top block 62 has a tendency to move forward, and then the top block 62 has a force to push the sensing module 50 forward, so that the sensing module 50 abuts against the surface cover 70.

[0056] refer to Figure 9 and Figure 10 A third elastic buckle 39 is provided on the inner wall of the rear shell 30, and a limiting groove 61 is provided on the outer peripheral wall of the top block 62.
