When the bristles 1231 are in the first state, the bristles 1231 penetrate through the through holes and then at least partially extend to the outside of the bottom cover assembly 124; when the bristles 1231 are in the second state, the bristles 1231 are retracted relative to the bottom cap assembly 124 and are received in the space defined by the bottom cap assembly 124 and the base 121. The bristles are broadly defined, and may be in the form of fluffy bristles, or may be in the form of short, thin, and flexible strips of rubber.

The hole wall of the air inlet 125 extends towards the base shell 121 to form a first annular rib 1252, the first annular rib 1252 sequentially penetrates through the bristle assembly 123 and the bearing plate 122 from bottom to top, and the bristle assembly 123 and the bearing plate 122 are respectively provided with an insertion opening for the first annular rib 1252 to penetrate through. The connecting member 1242 includes a second annular stud 1253 clamped with the first annular stud 1252, and extension arms are integrally formed on two sides of the second annular stud 1253, wherein the first annular stud 1252 and the second annular stud 1253 are part of the second air suction channel, and the bottom end of the second elastic member 1243 abuts against the bearing plate 122, and the top end abuts against the extension arms. Under the condition of no external force, the second elastic member 1243 can make the bottom cover 1241 abut against the bottom opening of the base shell 121, and at this time, at least a portion of the bristles 1231 is exposed to the outside of the brush head 120.

Referring to fig. 7, the adjusting assembly 130 includes a rotating member 131 pivotally connected to the handle 110 and abutting against the triggering member 112, an adjusting member 132 movably disposed in the first air suction channel 111 and the second air suction channel, and a first elastic member 133 disposed in the brush head 120 and acting on the adjusting member 132 to enable the adjusting member 132 to abut against the rotating member 131 without an external force, so that the adjusting member 132 and the rotating member 131 are reset. The adjusting member 132 is formed with a connection passage 1321 for communicating the first suction passage 111 and the second suction passage, and the flow section of the connection passage 1321 is smaller than the suction opening 125. Thus, when the adjusting member 132 moves to the air suction opening 125, the caliber of the air suction opening 125 can be reduced, thereby increasing the negative pressure at the air suction opening 125. When the trigger 112 is in the first operating position, the upper portion of the connecting passage 1321 is located in the first suction passage 111 and the lower portion of the connecting passage 1321 is located in the second suction passage. When the trigger 112 is in the second operating position, the adjustment member 132 is generally positioned within the second suction channel. In the present application, the first suction passage 111, the second suction passage, and the connection passage 1321 collectively constitute the above-described air flow passage.

In order to ensure the stability and reliability of the resetting operation of the adjusting member 132, the supporting plate 122 is provided with a second guiding column 1221 for guiding the movement of the first elastic member 133, and the first elastic member 133 is sleeved on the second guiding column 1221. Referring to fig. 8, the adjusting member 132 includes a sleeve portion formed with the connecting passage 1321 and an abutting portion 1323 fixed on the top of the sleeve portion and abutting against the rotating member 131. A boss 1324 is formed at the joint of the sleeve portion and the abutting portion 1323, the boss 1324 is distributed perpendicular to the axial extending direction of the connecting passage 1321, and a guide hole 1325 for the second guide column 1221 to penetrate is formed in the boss 1324.

In order to allow the adjuster 132 to move the bottom cover assembly 124 downward together during downward movement. The adjusting member 132 further has a locking portion 1322 formed thereon, wherein the locking portion 1322 is configured to be capable of abutting against the bottom cover assembly 124 and moving the bottom cover assembly 124 together during the movement of the adjusting member 132 toward the air suction opening 125. Specifically, the locking portion 1322 is a locking block fixed on the bottom end surface of the boss 1324 and extending toward the bottom cover assembly 124, and in the process that the adjusting element 132 moves toward the air suction opening 125, the locking portion 1322 will abut against the second annular rib 1253 of the connecting element 1242, so as to drive the bottom cover assembly 124 to move downward together.

In the present application, in order to reduce the amount of hair entanglement on the adjustment assembly 130, the catching portion 1322, the rotating member 131, and the first elastic member 133 are located outside the air flow channel. The adjuster 132 is partially located inside the airflow passage and partially located outside the airflow passage, specifically, the sleeve portion of the adjuster 132 is located inside the airflow passage, and the abutting portion 1323 extends to the outside of the airflow passage to abut against the rotator 131.

In order to reduce the wind resistance of the air flow entering the air suction opening 125, a first wind guiding surface 1251 is formed at the air suction opening 125 for guiding the wind. The first air guiding surface 1251 is in a bell mouth shape with a large lower end and a small upper end, and when the trigger 112 moves from the first working position to the second working position, the air inlet of the connecting channel 1321 near the air suction opening 125 moves to the first air guiding surface 1251. In order to further improve the air guiding effect, a second air guiding surface 1326 is further formed at the air inlet of the connecting channel 1321, and the second air guiding surface 1326 is also in a bell mouth shape with a large lower end and a small upper end.
