Referring to FIGS. 1 to 3, the present application provides an adjustment assembly, which includes a display screen, a display circuit board 223, a fixed connection board 224, an encoder 232, a knob assembly, a first flexible flat cable and a second flexible flat cable. The encoder 232 includes a fixed seat 2321 and a rotation sleeve 2322 sleeved on the fixed seat 2321. The knob assembly is formed with an installation cavity inside, and the display screen, the fixed connection board 224 and the encoder 232 are arranged in the installation cavity. The fixed seat 2321 is connected to the housing 10, the fixed connection board 224 is connected to a side of the fixed seat 2321 away from the housing 10, the display screen is connected to a side of the fixed connection board 224 away from the housing 10, and the display circuit board 223 is connected to a side of the display screen facing the fixed connection board 224. The fixed connection board 224 is provided with a cable threading hole 2241.

One end of the second flexible flat cable is electrically connected to the fixed seat 2321, and the other end of the second flexible flat cable is threaded through the cable threading hole 2241 to be electrically connected to the main circuit board.

The adjustment assembly in the technical solution of the present application includes the display screen, the display circuit board 223, the fixed connection board 224, the encoder 232, the knob assembly, the first flexible flat cable and the second flexible flat cable. The encoder 232 includes the fixed seat 2321 and the rotation sleeve 2322 sleeved on the fixed seat 2321. The knob assembly is formed with the installation cavity inside, and the display screen, the fixed connection board 224 and the encoder 232 are arranged in the installation cavity. In this way, the display screen is allowed to be integrated into the knob assembly inside the knob assembly, thereby reducing the space occupied by the display screen. Furthermore, the fixed seat 2321 is connected to the housing 10, the fixed connection board 224 is connected to a side of the fixed seat 2321 away from the housing 10, the display screen is connected to a side of the fixed connection board 224 away from the housing 10, and the display circuit board 223 is connected to a side of the display screen facing the fixed connection board 224. The fixed connection board 224 is provided with the cable threading hole 2241. One end of the first flexible flat cable is electrically connected to the display circuit board 223, and the other end of the first flexible flat cable is threaded through the cable threading hole 2241 to be electrically connected to the main circuit board. One end of the second flexible flat cable is electrically connected to the fixed seat 2321, and the other end of the second flexible flat cable is threaded through the cable threading hole 2241 to be electrically connected to the main circuit board. By providing the cable threading hole 2241 on the fixed connection board 224, the fixed seat 2321 and the display circuit board 223 are thus allowed to be electrically connected to the main circuit board directly via the first flexible flat cable and the second flexible flat cable, respectively, thereby reducing the possibility of the electrical connection between the display circuit board 223 and the fixed seat 2321 and the main circuit board becoming loose resulting from the adjustment assembly being knocked, and prolonging the service life of the adjustment assembly.

Specifically, the adjustment assembly can be used for adjusting the air output size, the air output humidity, the brightness of the display screen, the opening size of the aromatherapy box at the air outlet, and other air output parameters of the adjustment assembly.

Referring to FIG. 6, in an embodiment, the diameter of the cable threading hole 2241 ranges from 15 mm to 25 mm. In this way, not only the first flexible flat cable and the second flexible flat cable are allowed to have a certain movement space, but also the shaking amplitude of the first flexible flat cable and the second flexible flat cable is reduced, thereby reducing the possibility of the electrical connection between the display circuit board 223 and the fixed seat 2321 and the main circuit board becoming loose, and prolonging the service life of the adjustment assembly.

Referring to FIGS. 2, 3 and 7, in an embodiment, the knob assembly includes a knob ring 231, the knob ring 231 is formed with the installation cavity. The knob ring 231 is sleeved on a periphery surface of the display screen and drivingly connected to the rotation sleeve 2322. When the user rotates the knob ring 231 to drive the rotation sleeve 2322 to rotate, the fixed seat 2321 of the encoder 232 obtains the rotation information of the rotation sleeve 2322, the rotation information is then transmitted to the main circuit board, and triggering corresponding functions.

Referring to FIGS. 2, 3, 5 and 8, in an embodiment, the knob assembly further includes a transmission member 233, the transmission member 233 is provided on the rotation sleeve 2322, the knob ring 231 is provided on the transmission member 233, the knob ring 231 is drivingly connected to the rotation sleeve 2322 via the transmission member 233, and the transmission member 233 and the knob ring 231 enclose to form the installation cavity. By using the transmission member 233 to realize the drive connection between the knob ring 231 and the rotation sleeve 2322, the transmission path is increased. Additionally, since the user will often touch the knob ring 231, and the knob ring 231 protrudes from the surface of the housing 10, the knob is thus easily damaged. Therefore, by providing the knob ring 231 and the transmission member 233 separately, it is thus beneficial to replace the knob, which reduces the daily use and maintenance cost.

In an embodiment, one of the transmission member 233 and the rotation sleeve 2322 is provided with a first clamping catch 2335, and the other is provided with a first clamping groove 2324. The transmission member 233 is connected to the rotation sleeve 2322 via the first clamping catch 2335 and the first clamping groove 2324. After the first clamping catch 2335 on the transmission member 233 and the first clamping groove 2324 on the rotation sleeve 2422 are aligned, inserting the transmission member 233 to the rotation sleeve 2322 upwards along the axis of the knob ring 231 until the first clamping catch 2335 is abutted against the groove wall of the first clamping groove 2324. In this way, the transmission member 233 is restricted in the circumferential direction, and is only restricted in one direction in the axial direction, which is beneficial for the installation and removal of the transmission member 233 and the rotation sleeve 2322. The clamping restriction method of the first clamping catch 2335 and the first clamping groove 2324 is stable and reliable, the connection is convenient and the cost is low.

In an embodiment, one of the knob ring 231 and the transmission member 233 is provided with a first restriction protrusion 2334, and the other is provided with a first restriction groove 2311. The knob ring 231 is restricted to the transmission member by the cooperation of the first restriction protrusion 2334 and the first restriction groove 2311. The first restriction protrusion 2334 and the first restriction groove are extended radially, and this allows that when rotating the knob ring 231, the transmission member 233 can be driven to rotate by the cooperation of the first restriction protrusion 2334 and the first restriction groove 2311, which increases the synchronicity between the knob ring 231 and the transmission member 233, reduces the possibility of slippage between the knob ring 231 and the transmission member 233, improves the stability between the knob ring 231 and the transmission member 233, and improves the control accuracy of the knob ring 231.

In an embodiment, the periphery surface of the knob ring 231 is provided with a plurality of anti-slip protrusions at intervals, which facilitates the user to rotate the knob ring 231, improving the friction of the periphery surface of the knob ring 231, and improving the user's experience.

In an embodiment, the adjustment assembly further includes a connection support 21, the fixed seat 2321 is fixed to the housing 10 via the connection support 21. One of the connection support 21 and the fixed seat 2321 is provided with a second restriction protrusion 211, and the other is provided with a second restriction groove 2323. The connection support 21 is restricted and installed to the fixed seat 2321 by the cooperation of the second restriction protrusion 211 and the second restriction groove 2323. There can be multiple second restriction protrusions 211 and second restriction grooves 2323 arranged with intervals, one second restriction protrusion 211 corresponds to one second restriction groove 2323, and the length and width of multiple second restriction protrusions 211 may differs from each other. In this way, the connection support 21 is thus restricted to the fixed seat 2321 via the second restriction protrusions 211 and the second restriction grooves 2323, and the connection support 21 is allowed to be inserted into the fixed seat 2321 only along the axial direction of the knob ring 231. The structures of the second restriction protrusion 211 and the second restriction groove 2323 are simple, the installation is convenient, and the connection strength is high.

Referring to FIGS. 3 and 5, in an embodiment, the transmission member 233 includes a first sleeve 2331, a second sleeve 2333 and a ring-shaped connection board 2332. One end of the ring-shaped connection board 2332 is connected to the first sleeve 2331, and the other end is connected to the second sleeve 2333. The first sleeve 2331 is connected to the knob ring 231, and the second sleeve 2333 is connected to the rotation sleeve 2322. The ring-shaped connection board 2332 and the fixed connection board 224 are spaced apart, and the diameter of the ring-shaped connection board 2332 is configured to gradually increase along the direction from the second sleeve 2333 to the first sleeve 2331. It can be understood that since the adjustment assembly protrudes from the surface of the housing 10, the adjustment assembly is easily knocked by other objects. In this condition, the first sleeve 2331 and the ring-shaped connection board 2332 can also play a restriction role for the fixed connection board 224, avoiding the adjustment assembly from being greatly offset when being knocked, thereby prolonging the service life of the adjustment assembly.

In an embodiment, the distance between the ring-shaped connection board 2332 and the fixed connection board 224 is defined as s, and 0<s≤2 mm. When s is 0, then when the knob ring 231 drives the transmission member 233 to rotate, a friction will occur between the transmission member 233 and the fixed connection board 224, thereby generating noise and also increasing the force of the user to rotate the knob ring 231, which reduces the user's experience. When s is greater than 2 mm, the distance between the ring-shaped connection board 2332 and the fixed connection board 224 is relatively large, and the ring-shaped connection board 2332 cannot play a support role on the fixed connection board 224, thereby reducing the reliability of the adjustment assembly.

In an embodiment, the fixed connection board 224 is provided with soldering holes 2242. One side of the fixed seat 2321 facing the fixed connection board 224 is provided with a soldering board, and the soldering board is soldered to the soldering hole 2242. The soldering board and the soldering hole 2242 can play a certain restriction role, but also, the connection strength between the fixed connection board 224 and the fixed seat 2321 is further improved by soldering the soldering board to the soldering hole 2242. Meanwhile, the soldering process is mature, and connection strength is high, thereby reducing the manufacturing cost and improving the connection strength between the fixed connection board 224 and the fixed seat 2321.

Referring to FIGS. 2 and 4, in an embodiment, one side of the display screen facing the fixed connection board 224 is provided with restriction columns 2211, and the periphery surface of the display circuit 223 is provided with restriction holes 2231. The restriction columns 2211 is restricted in the restriction holes 2231, and the display circuit board 223 is adhered to the display screen. The display circuit board 223 is adhered to one side of the display screen facing the fixed connection board 224. The stability of the display circuit board 223 is further increased by the cooperation of the restriction columns 2211 and restriction holes 2231, and the possibility of the display circuit 223 becoming loose is reduced, thereby improving the stability of the adjustment assembly.

In an embodiment, the fixed connection board 224 is provided with installation holes 2243, the restriction columns 2211 are each provided with a threaded hole inside. One installation hole 2243 corresponds to one threaded hole. The display screen is fastened to the fixed connection board 224 via the threaded holes, the installation holes 2243 and screws. The method of using screws to fasten is stable and reliable, and the connection strength is high; the installation is convenient, and the cost is low.

In an embodiment, the adjustment assembly further includes springs 234, the display screen includes a display screen body 221 and a touch display panel 222 provided on the display screen body. The touch display panel 222 has a press zone and a display zone on it. The display screen body 221 is provided with spring trough holes 2212, the spring trough holes 2212 are configured to correspond to the press zone. The springs 234 are arranged in the spring through holes 2212, one end of the spring is electrically connected to the touch display panel 222, and the other end of the spring is electrically connected to the display circuit 223. The springs 234 play a conductive role for the electrical connection between the touch display panel 222 and the display circuit 223, and the electrical connection between touch display panel 222 and the display circuit 223 is thus a flexible connection, thereby increasing the stability of the electrical connection between the touch display panel 222 and the display circuit 223 and prolonging the service life of the adjustment assembly.

The above-mentioned are only some preferred embodiments of the present application, and are not intended to limit the scope of the present application.
