[0055] Please refer to FIG. 2 、 FIG. 4 and FIG. 5 In an embodiment of the present application, the humidifying module 30 comprises a water tank 31, an atomizing assembly and an electric control assembly. The water tank 31 is used to be detachably installed in the air duct 15 of the air treatment device 100, and has an inbuilt state used in the air duct 15 and an external state used outside the air duct 15.

[0056] In the embodiment, the water tank 31 of the humidifying module 30 is used to be detachably mounted in the air duct 15 of the air treatment device 100, specifically, when the humidifying module 30 is assembled into the air duct 15 of the air treatment device 100 for use, the water tank 31 is in an internal state, and when the humidifying module 30 is placed outside the air duct 15 of the air treatment device 100 for independent use, the water tank 31 is in an external state. The water tank 31 is used to store humidifying solution, wherein the humidifying solution can be clean tap water or disinfectant, and generally water is usually used for humidification. The shape of the water tank 31 can be set according to actual needs, for example, it can be designed as a ring, a circle, a square, etc., as long as the water tank 31 does not completely block the flow path of the air flow after being assembled into the air duct 15 of the air treatment device 100. The atomizing assembly and the electric control assembly are both arranged in the water tank 31, the electric control assembly is used to control the working state of the atomizing assembly, and the atomizing assembly is used to atomize and disperse the solution in the water tank 31 into small droplets and then spray them out, realizing the atomizing and humidifying function.

[0057] The technical scheme of the present application can make the humidifying module 30 realize internal and external use by detachably mounting the water tank 31 of the humidifying module 30 in the air duct 15 of the air treatment device 100 and arranging the atomizing assembly and the electric control assembly on the water tank 31. Specifically, when the water tank 31 is in the internal state of being placed in the air duct 15 for use, the electric control assembly controls the atomizing assembly to atomize and spray the solution in the water tank 31 towards the air duct 15, and with the flow of the air flow in the air duct 15, the atomized solution can be blown out through the air outlet 14 of the air duct 15, so that the humidifying function of the air treatment device 100 can be realized; and the air duct system (for example, the fan assembly 20 in the air duct 15) of the air treatment device 100 can accelerate the diffusion and flow of the atomized liquid, so that the humidifying module 30 can be used cooperatively with the air treatment device 100 to achieve the optimal humidifying effect. When the water tank 31 is in the external state of being placed outside the air duct 15 for use, the electric control assembly controls the atomizing assembly to atomize and spray the solution in the water tank 31 towards the external environment, at this time the humidifying module 30 can be used as an independent humidifier, and the humidifying module 30 can be freely taken to any room for use, and its use position is not limited, so that the maximum effect can be achieved. The novel humidifying module 30 can be used cooperatively with the air treatment device 100 to achieve the optimal humidifying effect, and can also be freely taken to any room for independent use, so as to meet different use requirements of users.

[0058] Please refer to FIG. 4 and FIG. 5In one of the embodiments, the atomization assembly includes an internal atomization head 32 and an external atomization head 33, the internal atomization head 32 is used to atomize and spray the solution in the water tank 31 towards the air duct 15, the external atomization head 33 is used to atomize and spray the solution in the water tank 31 towards the external environment, and the electronic control assembly is used to control one of the internal atomization head 32 and the external atomization head 33 to be in the power-on state and the other to be in the power-off state.

[0059] Specifically, in the present embodiment, the internal atomization head 32 and the external atomization head 33 can be respectively installed at different positions of the water tank 31, wherein the internal atomization head 32 and the external atomization head 33 can adopt ultrasonic atomization heads, which can achieve better atomization effect. Alternatively, the internal atomization head 32 and the external atomization head 33 can adopt micro-porous ultrasonic atomization heads which do not need to be soaked in water. Specifically, the internal atomization head 32 and the external atomization head 33 can include an atomization sheet arranged on the water tank 31 and a water-absorbing cotton connected with the atomization sheet, the water-absorbing cotton absorbs the solution in the water tank 31 and continuously delivers the solution to the atomization sheet through capillary effect, and the atomization sheet can disperse the solution into tiny droplets when working in power-on state, thereby realizing the atomization and humidification function. The internal atomization head 32 and the external atomization head 33 are electrically connected with the electronic control assembly, and the electronic control assembly is used to control one of the internal atomization head 32 and the external atomization head 33 to be in the power-on state and the other to be in the power-off state; for example, in the internal state, the electronic control assembly controls the internal atomization head 32 to work in power-on state and the external atomization head 33 to work in power-off state; the solution in the water tank 31 is atomized and sprayed into the air duct 15 by the internal atomization head 32, and flows with the airflow in the air duct 15, which can drive the atomized solution to be blown out through the air outlet 14 of the air duct 15, thereby realizing the cooperative humidification function of the humidification module 30 and the air handling device 100. In the external state, the electronic control assembly controls the external atomization head 33 to work in power-on state and the internal atomization head 32 to work in power-off state, and the solution in the water tank 31 is atomized and sprayed towards the external environment by the external atomization head 33, thereby realizing the independent humidification function of the humidification module 30. The number of the internal atomization head 32 and the external atomization head 33 can be set according to actual needs, which can be one, two or more. By setting multiple internal atomization heads 32 and multiple external atomization heads 33, the humidification amount and efficiency can be improved. The installation position and direction of the internal atomization head 32 and the external atomization head 33 are flexible, which can be suitable for different application scenarios and realize rapid and efficient humidification.

[0060] In order to enable the humidification module 30 to be better used with the air duct 15 system of the air handling device 100, in one of the embodiments, as shown in FIG. 5As shown, the water tank 31 has oppositely and spacedly arranged inner ring wall 311 and outer ring wall 312, and side ring wall 314 connected between the inner ring wall 311 and the outer ring wall 312, the inner ring wall 311, the outer ring wall 312 and the side ring wall 314 enclose a water storage cavity, the inner ring wall 311 away from the outer ring wall 312 side enclose a wind passage 313 communicated with the air duct 15, the built-in atomizing head 32 is arranged on the inner ring wall 311, and the external atomizing head 33 is arranged on the outer ring wall 312 and / or the side ring wall 314.

[0061] Specifically, the water tank 31 is arranged in a ring shape, as shown in FIG. 4 and FIG. 5 As shown, in this embodiment, the water tank 31 is generally in the shape of a "back" structure, the inner ring of the water tank 31 forms the inner ring wall 311, the outer ring of the water tank 31 forms the outer ring wall 312, and the left and right sides of the water tank 31 form the side ring wall 314 respectively, and the inner ring wall 311, the outer ring wall 312 and the two side ring walls 314 together enclose a liquid storage cavity, and the inner ring wall 311 itself encloses a left-right through wind passage 313. The built-in atomizing head 32 is arranged on the inner ring wall 311 and used for atomizing and spraying the solution in the water storage cavity towards the wind passage 313, and the external atomizing head 33 is arranged on the outer ring wall 312 and / or the side ring wall 314 and used for atomizing and spraying the solution in the water storage cavity towards the external environment.

[0062] When the water tank 31 is in the built-in state placed in the air duct 15, the air duct 15 is in communication with the air passage 313, the fan assembly 20 of the air treatment device 100 is opposite to the air passage 313, and the built-in atomizing head 32 sprays the solution in the storage cavity towards the air passage 313, which can be rapidly diffused with the airflow in the air duct 15 under the action of the fan assembly 20, thereby realizing the optimal humidification effect. By arranging the water tank 31 in a ring shape, forming the air passage 313 penetrating through the two ends in the middle of the water tank 31, and arranging the built-in atomizing head 32 on the inner ring wall 311 of the water tank 31, the atomized solution sprayed by the built-in atomizing head 32 can be concentrated in the air passage 313 in the built-in state, and then rapidly diffused with the airflow under the action of the fan assembly 20, and forming the air passage 313 on the water tank 31 can minimize the blocking area of the water tank 31 to the air duct 15, so that the airflow in the air duct 15 can flow smoothly through the air passage 313, thereby not affecting other functions of the air treatment device 100. In addition, the water tank 31 is arranged in a ring shape, which can maximize the volume of the water tank 31 while minimizing the blocking to the air duct 15, so as to ensure that the storage cavity has sufficient capacity, thereby prolonging the use time of the humidification module 30 and reducing the frequency of water replenishment. In this way, the humidification module 30 and the air treatment device 100 are used in multiple ways, which can realize the optimal humidification effect. In addition, the external atomizing head 33 is arranged on the outer ring wall 312 and / or the side ring wall 314 of the water tank 31, and in the external state, the external atomizing head 33 is powered on. Since the outer side of the outer ring wall 312 and the side ring wall 314 is not blocked by other structures, the external atomizing head 33 can directly spray the solution in the storage cavity to the external environment, thereby ensuring the humidification effect. In addition, in the external state, the built-in atomizing head 32 is in a power-off state, which can avoid the accumulation of atomized liquid when the built-in atomizing head 32 is working.

[0063] For the convenience of description, the water tank 31 in the built-in state as shown in FIG. 4 is taken as a reference when the up-down direction is described below, that is, the bottom of the water tank 31 is downward in the built-in state, and the top of the water tank 31 is upward in the built-in state. In one embodiment, the external atomizing head 33 is located at the bottom of the water tank 31 in the built-in state, and the water tank 31 in the external state is inverted relative to the water tank 31 in the built-in state in the direction of gravity. Specifically, as shown in FIG. 4 , the external atomizing head 33 is located at the bottom of the water tank 31 in the built-in state; when the humidification module 30 needs to be used independently in the external state, the water tank 31 is taken out of the air duct 15 and inverted by 180°, so that the water tank 31 is switched from the built-in state to the external state as shown in FIG. 5As shown in the external state, the external atomization head 33 is located at the top of the water tank 31 to facilitate humidification to the external environment through the external atomization head 33.

[0064] In order to be able to more accurately control the working state of the built-in atomization head 32 and the external atomization head 33, please combine FIG. 6 to FIG. 13 In some embodiments, the electric control assembly includes a state detection unit 34 for detecting whether the water tank 31 is in a built-in state or an external state, and a control circuit 35 for controlling the on-off state of the built-in atomization head 32 and the external atomization head 33 according to the signal fed back by the state detection unit 34. Specifically, when the state detection unit 34 detects that the water tank 31 is in the built-in state, it feeds back a first signal to the control circuit 35, and the control circuit 35 controls the built-in atomization head 32 to be powered on according to the first signal fed back by the state detection unit 34. The external atomization head 33 is in a power-off state. When the state detection unit 34 detects that the water tank 31 is in the external state (i.e. the water tank 31 is flipped relative to the built-in state), it feeds back a second signal to the control circuit 35, and the control circuit 35 controls the external atomization head 33 to be powered on according to the second signal fed back by the state detection unit 34. The built-in atomization head 32 is in a power-off state. Wherein, the state detection unit 34 can realize mechanical contact type state detection of the humidification module 30 through pure mechanical structure; or the state detection unit 34 can also realize inductive state detection of the humidification module through the cooperation of the sensor 348 and the inductor 349, so as to judge whether the water tank 31 is in the built-in state or the external state.

[0065] As FIG. 6 to FIG. 10 shown, in some embodiments, the state detection unit 34 includes a bracket 341, a first conductive member 342, a second conductive member 343, and a movable conductive member 344. The first conductive member 342 and the second conductive member 343 are arranged on both sides of the bracket 341 along the direction of gravity. The movable conductive member 344 is movably arranged between the first conductive member 342 and the second conductive member 343. When the water tank 31 is flipped between the built-in state and the external state, the movable conductive member 344 can move to contact one of the first conductive member 342 and the second conductive member 343.

[0066] In the embodiment, the state detecting unit 34 can be fixed on the water tank 31 by the bracket 341, the first and second conductive pieces 342 and 343 can be conductive pieces arranged on opposite sides of the bracket 341 along the gravity direction, and the movable conductive piece 344 can be a metal weight movable along the gravity direction. When the water tank 31 is flipped between the built-in state and the external state, the movable conductive piece 344 can be moved to contact one of the first and second conductive pieces 342 and 343, so that the state of the water tank 31 can be detected, and then the control circuit 35 can control the on-off state of the built-in and external atomizing heads 32 and 33 according to the state of the water tank 31. For example, when the water tank 31 is in the built-in state, the movable conductive piece 344 contacts the first conductive piece 342, and when the water tank 31 is flipped from the built-in state to the external state, the movable conductive piece 344 contacts the second conductive piece 343, indicating that the water tank 31 has been switched to the external state.

[0067] Further, the control circuit 35 has a power input end, the movable conductive piece 344 is electrically connected to a first pole of the power input end, the built-in atomizing head 32 is connected between the first conductive piece 342 and a second pole of the power input end, and the external atomizing head 33 is connected between the second conductive piece 343 and the second pole of the power input end.

[0068] Specifically, the control circuit 35 has a power input end, which can be used for external power supply to energize the control circuit 35. The power input end has a first pole and a second pole, when the first pole is positive, the second pole is negative, and when the first pole is negative, the second pole is positive. For example, in the embodiment, the first pole is positive and the second pole is negative, as shown in FIG. 4, the movable conductive piece 344 is connected to the positive pole of the power input end, the built-in atomizing head 32 is connected between the first conductive piece 342 and the negative pole of the power input end through a first line, and the external atomizing head 33 is connected between the second conductive piece 343 and the negative pole of the power input end through a second line. Of course, in other embodiments, the first pole can be negative and the second pole can be positive. FIG. 10

[0069] ​When the humidifying module 30 is used in cooperation with the air treatment device 100, the water tank 31 is in the built-in state, the first conductive part 342 is located below the second conductive part 343, and the movable conductive part 344 moves to contact the first conductive part 342 under the action of gravity; at this time, the first pole (for example, the positive pole) of the power input end, the movable conductive part 344, the first conductive part 342, the built-in atomizing head 32, and the second pole (for example, the negative pole) of the power input end form a closed loop, so that the built-in atomizing head 32 is in an energized working state, and since the second conductive part 343 is disconnected from the movable conductive part 344, the external atomizing head 33 is in a de-energized state. When the humidifying module 30 is used independently, the water tank 31 is taken out of the air duct 15 of the air treatment device 100 and then is turned over and inverted by 180°, so that the water tank 31 is switched from the built-in state to the external state, the second conductive part 343 is located below the first conductive part 342, and the movable conductive part 344 moves to contact the second conductive part 343 under the action of gravity; at this time, the first pole (for example, the positive pole) of the power input end, the movable conductive part 344, the second conductive part 343, the external atomizing head 33, and the second pole (for example, the negative pole) of the power input end form a closed loop, so that the external atomizing head 33 is in an energized working state, and since the first conductive part 342 is disconnected from the movable conductive part 344, the built-in atomizing head 32 is in a de-energized state. In this way, the humidifying module 30 can realize mechanical contact type state detection and further realize switching of the energized and de-energized states of the built-in atomizing head 32 and the external atomizing head 33 through a simple mechanical structure.

[0070] Please combine FIG. 4 and FIG. 6 In one of the embodiments, the water tank 31 includes a water tank body 31a and a water tank panel 31b arranged on one side of the water tank body 31a, and a mounting cavity for mounting the state detection unit 34 is formed between the water tank body 31a and the water tank panel 31b. A liquid storage cavity is formed in the water tank body 31a, and the mounting cavity and the liquid storage cavity are independent of each other, so that water and electricity can be separated, thereby ensuring the safety of the humidifying module 30. The state detection unit 34 can be fixed in the mounting cavity by a support 341, wherein the support 341 can include a first fixed plate and a second fixed plate arranged in a spaced manner in the up-down direction, a first bending plate bent outward from a side of the first fixed plate close to the second fixed plate, a second bending plate bent outward from a side of the second fixed plate close to the first fixed plate, and a vertical connecting plate connected between the first bending plate and the second bending plate.

[0071] Specifically, the first fixed plate and the second fixed plate of the bracket 341 can be connected and fixed with the water tank body 31a by means of fasteners, adhesion or snap connection, etc. The vertical connecting plate and the water tank body 31a form a recess for accommodating the movable electrically-conductive member 344. The first electrically-conductive member 342 is fixed to the first fixed plate, the second electrically-conductive member 343 is fixed to the second fixed plate, the first bent plate is provided with a first opening for the first electrically-conductive member 342 to extend into the recess, and the second bent plate is provided with a second opening for the second electrically-conductive member 343 to extend into the recess. When the water tank 31 is in the built-in state, the first bent plate is located below the second bent plate, the movable electrically-conductive member 344 abuts against the first bent plate, and the movable electrically-conductive member 344 is limited by the first bent plate. At the same time, the movable electrically-conductive member 344 can form stable electrical contact with the first electrically-conductive member 342 extending into the recess from the first opening, so as to enable the built-in atomizing head 32 to work under power. When the water tank 31 is flipped and inverted to the external state, the second bent plate is located below the first bent plate, the movable electrically-conductive member 344 abuts against the second bent plate, and the movable electrically-conductive member 344 is limited by the second bent plate. At the same time, the movable electrically-conductive member 344 can form stable electrical contact with the second electrically-conductive member 343 extending into the recess from the second opening, so as to enable the external atomizing head 33 to work under power.

[0072] In the above embodiments, there are various ways to enable the movable electrically-conductive member 344 to freely move along the direction of gravity while ensuring that the movable electrically-conductive member 344 forms stable electrical connection with the first pole of the power input end. For example, FIG. 6 and FIG. 7 In one of the embodiments, the movable electrically-conductive member 344 is electrically connected with the first pole of the power input end through a soft wire 345. When the water tank 31 is flipped and switched between the built-in state and the external state, the soft wire 345 can swing together with the movable electrically-conductive member 344 and will not hinder the free movement of the movable electrically-conductive member 344.

[0073] For example, FIG. 8 and FIG. 9As shown, in another embodiment, the bracket 341 is fixed with a conductive pressure piece 346, and the movable conductive piece 344 is arranged between the bracket 341 and the conductive pressure piece 346. When the water tank 31 is flipped between the built-in state and the external state, the movable conductive piece 344 can move along the conductive pressure piece 346 and keep contact with the conductive pressure piece 346, and the movable conductive piece 344 is electrically connected with the first pole of the power input end via the conductive pressure piece 346. In this embodiment, the conductive pressure piece 346 is electrically connected with the first pole of the power input end, and when the water tank 31 is flipped between the built-in state and the external state, the movable conductive piece 344 can rub and keep contact with the conductive pressure piece 346, so as to ensure that the movable conductive piece 344 can always be electrically connected with the first pole of the power input end. In order to ensure that the movable conductive piece 344 and the conductive pressure piece 346 are in good contact, the conductive pressure piece 346 can be an elastic pressure piece, and the conductive pressure piece 346 is pressed on the surface of the movable conductive piece 344 through elastic action, so as to ensure that the movable conductive piece 344 and the conductive pressure piece 346 keep close contact.

[0074] In the above embodiments, the state detection unit 34 is used to realize mechanical contact type state detection of the humidifying module 30 through a pure mechanical structure. Of course, in other embodiments, the state detection unit 34 can also be used to realize inductive type state detection of the humidifying module 30 through cooperation of the sensor 348 and the inductive piece 349. For example, as shown in FIG. 6, the state detection unit 34 includes a bracket 347, a sensor 348 and an inductive piece 349. The sensor 348 is fixed to one side of the bracket 347 along the direction of gravity, and the inductive piece 349 is movably arranged on the bracket 347. When the water tank 31 is flipped between the built-in state and the external state, the inductive piece 349 can move to be staggered with or aligned with the sensor 348. FIG. 11 to FIG. 13

[0075] ​In the embodiment, the state detecting unit 34 is fixed on the water tank 31 by the fixing frame 347, and the sensor 348 is fixed on the fixing frame 347 at the side along the gravity direction, for example, the sensor 348 is fixed on the lower side of the fixing frame 347 with the water tank 31 in the built-in state as the reference. When the water tank 31 is flipped between the built-in state and the external state, the inductor 349 can be switched between the misaligned state and the aligned state with the sensor 348, and then the sensor 348 can send two different signals to the control board 36. The sensor 348 includes but is not limited to the magnetic induction sensor, the photoelectric sensor, etc. For example, in the embodiment, the sensor 348 is the magnetic induction sensor, and the inductor 349 is the magnetic member (for example, the magnet). When the magnetic member is aligned or misaligned with the magnetic induction sensor 348, the magnetic field can be changed, so that the magnetic induction sensor 348 sends two different signals. The magnetic induction sensor 348 includes but is not limited to the Hall sensor, the reed magnetic induction sensor, etc.

[0076] Further, the control circuit 35 has a power input end, the control board 36 is connected in series between the first pole and the second pole of the power input end, the sensor 348 is electrically connected with the control board 36, the built-in atomizing head 32 is connected between the control board 36 and the second pole of the power input end, and the external atomizing head 33 is connected between the control board 36 and the second pole of the power input end. The control board 36 is used for controlling the on-off state of the built-in atomizing head 32 and the external atomizing head 33 according to the signal fed back by the sensor 348.

[0077] Specifically, the control circuit 35 has a power input end, which can be used for external power supply to make the control circuit 35 powered on. The power input end has a first pole and a second pole. When the first pole is the positive pole, the second pole is the negative pole. When the first pole is the negative pole, the second pole is the positive pole. For example, in the embodiment, the first pole is the positive pole, and the second pole is the negative pole. The built-in atomizing head 32 is connected in series between the control board 36 and the negative pole of the power input end through the first line, and the external atomizing head 33 is connected in series between the control board 36 and the negative pole of the power input end through the second line. Of course, in other embodiments, the first pole can be the negative pole, and the second pole can be the positive pole.

[0078] Please refer to FIG. 13When the humidifying module 30 is used in cooperation with the air treatment device 100, the water tank 31 is in the built-in state, the inductive piece 349 moves to one side of the mounting frame 347 under the action of gravity, at this time the inductive piece 349 is aligned with (or offset from) the sensor 348, the sensor 348 sends a first signal to the control board 36, the control board 36 controls the first pole (for example, the positive pole) of the power input end, the built-in atomizing head 32 and the second pole (for example, the negative pole) of the power input end to be connected to form a closed loop, so that the built-in atomizing head 32 is in the energized working state, at the same time the control board 36 controls the external atomizing head 33 to be in the power-off state. When the humidifying module 30 is used independently, the water tank 31 is taken out from the air duct 15 of the air treatment device 100 and then is turned over and inverted by 180°, so that the water tank 31 is switched from the built-in state to the external state, the inductive piece 349 moves to the other side of the mounting frame 347 under the action of gravity, at this time the inductive piece 349 is offset from (or aligned with) the sensor 348, the sensor 348 sends a second signal to the control board 36, the control board 36 controls the first pole (for example, the positive pole) of the power input end, the external atomizing head 33 and the second pole (for example, the negative pole) of the power input end to be connected to form a closed loop, so that the external atomizing head 33 is in the energized working state, at the same time the control board 36 controls the built-in atomizing head 32 to be in the power-off state. Compared with the mechanical contact type state detection mode, the inductive type state detection of the present embodiment does not have the phenomenon of poor contact, and the detection is more reliable.

[0079] Please refer to FIG. 14 The detection operation principle schematic diagram of the humidifying module 30 of one of the embodiments is shown in FIG. 6. When the humidifying module 30 starts to be used, the state detection unit 34 judges whether the sensor 348 is aligned with the inductive piece 349, if the two are aligned, the built-in atomizing head 32 is controlled to be operated by the control board 36. When the state detection unit 34 judges that the sensor 348 is not aligned with the inductive piece 349, that is, the two are offset from each other, the external atomizing head 33 is controlled to be operated by the control board 36.

[0080] As FIG. 12As shown, in one embodiment, the mounting frame 347 can include a vertical plate, and a first horizontal plate and a second horizontal plate arranged on the upper and lower sides of the vertical plate, respectively. The first horizontal plate, the second horizontal plate and the vertical plate enclose a sliding groove for accommodating the inductor 349. The sensor 348 is fixed to the side of the vertical plate away from the sliding groove, and the sensor 348 is arranged on the side of the vertical plate along the direction of gravity. When the water tank 31 is in the built-in state, the first horizontal plate is located below the second horizontal plate, and the inductor 349 moves along the sliding groove under the action of gravity to abut against the first horizontal plate. At this time, the inductor 349 is aligned with the sensor 348, the sensor 348 sends a first signal to the control board 36, and the control board 36 controls the built-in atomizing head 32 to work under power supply according to the first signal fed back by the sensor 348. When the water tank 31 is turned upside down to become an external state, the second horizontal plate is located below the first horizontal plate, and the inductor 349 moves along the sliding groove under the action of gravity to abut against the second horizontal plate. At this time, the inductor 349 is misaligned with the sensor 348, the sensor 348 sends a second signal to the control board 36, and the control board 36 controls the external atomizing head 33 to work under power supply according to the second signal fed back by the sensor 348.

[0081] In order to make the humidifying module 30 more convenient to switch between the built-in state and the external state, as shown in FIG. 3 and FIG. 4 As shown, on the basis of the above embodiment, the control circuit 35 has two power input ends, the water tank 31 is provided with an electrical connection piece 37 and an adapter interface 38, the electrical connection piece 37 serves as one of the power input ends, and the adapter interface 38 serves as the other power input end. In the built-in state, the electrical connection piece 37 is used to be electrically connected with the power supply piece 40 of the air treatment device 100 to supply power to the control circuit 35. In the external state, the adapter interface 38 is used to be electrically connected with a power adapter to supply power to the control circuit 35.

[0082] Specifically, when the humidifying module 30 is used in cooperation with the air treatment device 100, the water tank 31 is in the built-in state, at this time, the power contact 37 on the water tank 31 is in contact with the power supply 40 of the air treatment device 100, and the control circuit 35 can be powered through the power supply 40, and the built-in atomizing head 32 is powered on. Among them, the power contact 37 and the power supply 40 can adopt elastic sheet contact power supply or contact contact power supply, and the main body 200 of the air treatment device 100 can supply power to the humidifying module 30, and the power supply voltage is safe low voltage. In order to ensure good contact between the power contact 37 and the power supply 40, the power contact 37 and the power supply 40 can be powered by elastic sheet contact. For example, the power contact 37 can include a first pole contact sheet 371 and a second pole contact sheet 372, and the power supply 40 can include a first pole power supply sheet and a second pole power supply sheet. In the built-in state, the first pole contact sheet 371 of the power contact 37 is in contact with and conducts the first pole power supply sheet of the power supply 40, and the second pole contact sheet 372 of the power contact 37 is in contact with and conducts the second pole power supply sheet of the power supply 40. When the humidifying module 30 is used independently, the water tank 31 is in the external state, and only needs to insert the power adapter of the external power supply into the adapter interface 38 on the water tank 31, so as to power the control circuit 35, and the external atomizing head 33 is powered on. In this way, the humidifying module 30 can be powered on in combination with the air treatment device 100 in the combined state, and can also be powered on by the power adapter in the independent use state, greatly improving the use convenience of the humidifying module 30.

[0083] In order to ensure that the humidifying module 30 can only work with the external atomizing head 33 in the external state, and can only work with the built-in atomizing head 32 in the built-in state, please refer to FIG. 15 and FIG. 16 On the basis of the above embodiment, the power contact 37 includes a first pole contact sheet 371 and a second pole contact sheet 372, the first pole contact sheet 371 is electrically connected to the first pole of the adapter interface 38, the second pole contact sheet 372 is electrically connected to the built-in atomizing head 32, and the second pole of the adapter interface 38 is electrically connected to the external atomizing head 33. Specifically, when the humidifying module 30 is used in cooperation with the air treatment device 100, the water tank 31 is in the built-in state, and the first pole contact sheet 371 and the second pole contact sheet 372 of the power contact 37 are respectively electrically connected to the first pole and the second pole of the power supply 40 of the air treatment device 100, at this time, the built-in atomizing head 32 is in the powered-on working state, and the external atomizing head 33 is in the power-off state; When the humidifying module 30 is used independently, the power adapter needs to be inserted into the adapter interface 38, and the water tank 31 is turned over and inverted so that the external atomizing head 33 is at the top of the water tank 31, and the external atomizing head 33 is powered on. The external atomizing head 33 can be powered on, and the external atomizing head 33 can be forced to work without shielding, preventing water from accumulating on the desktop or the ground.

[0084] For example, as shown in FIG. 6 and FIG. 15 one of the embodiments, the state detection unit 34 includes a bracket 341, a first conductive piece 342, a second conductive piece 343 and a movable conductive piece 344, the first conductive piece 342 and the second conductive piece 343 are arranged on both sides of the bracket 341 along the direction of gravity, and the movable conductive piece 344 is movably arranged between the first conductive piece 342 and the second conductive piece 343; the water tank 31 is provided with an electrical connection piece 37 and an adapter interface 38, the electrical connection piece 37 serves as one of the power input terminals of the control circuit 35, and the adapter interface 38 serves as another power input terminal of the control circuit 35; the first pole of the electrical connection piece 37 and the first pole of the adapter interface 38 are electrically connected with the movable conductive piece 344, the first conductive piece 342 and the built-in atomizing head 32 are electrically connected with the second pole of the electrical connection piece 37, and the second conductive piece 343 and the external atomizing head 33 are electrically connected with the second pole of the adapter interface 38. When the humidifying module 30 is used in cooperation with the air treatment device 100, the water tank 31 is in the built-in state, the electrical connection piece 37 is in contact with and conducts the power supply piece 40 of the air treatment device 100, at the same time, the first conductive piece 342 is in contact with and conducts the movable conductive piece 344, so that the built-in atomizing head 32 is powered on and works. When the humidifying module 30 is used independently, the water tank 31 needs to be taken out from the air duct 15 and turned upside down, so that the second conductive piece 343 is in contact with and conducts the movable conductive piece 344, at the same time, the power adapter needs to be connected with the adapter interface 38, so that the external atomizing head 33 is powered on and works; if only the adapter interface 38 is connected with the power adapter after the water tank 31 is taken out, because the water tank 31 is not turned upside down, the second conductive piece 343 is not in contact with the movable conductive piece 344, at this time, the external atomizing head 33 will not be powered on and work, so that the external forced turning function of the humidifying module 30 can be realized.

[0085] For example, as shown in FIG. 11 and FIG. 16As shown, in another embodiment, the state detection unit 34 comprises a mounting frame 347, a sensor 348 fixed to one side of the mounting frame 347 along the direction of gravity, and a sensing piece 349 movably arranged on the mounting frame 347; the water tank 31 is provided with an electrical connection piece 37 and an adapter interface 38, the electrical connection piece 37 serving as one power input terminal of the control circuit 35, and the adapter interface 38 serving as another power input terminal of the control circuit 35; the first pole of the electrical connection piece 37 and the first pole of the adapter interface 38 are electrically connected with the control board 36, the built-in atomizing head 32 is connected between the control board 36 and the second pole of the electrical connection piece 37, and the external atomizing head 33 is connected between the control board 36 and the second pole of the adapter interface 38. When the humidifying module 30 is used in cooperation with the air treatment device 100, the water tank 31 is in the built-in state, the electrical connection piece 37 is in contact with the power supply piece 40 of the air treatment device 100 and is conductive, and the sensing piece 349 is aligned with the sensor 348, the sensor 348 sends a first signal to the control board 36, the control board 36 controls the first pole of the electrical connection piece 37, the built-in atomizing head 32 and the second pole of the electrical connection piece 37 to be connected to form a closed loop, so as to make the built-in atomizing head 32 work under power. When the humidifying module 30 is used independently, the water tank 31 needs to be taken out of the air duct 15 and turned upside down so that the sensing piece 349 is misaligned with the sensor 348, and at the same time, the power adapter needs to be connected with the adapter interface 38, the sensor 348 sends a second signal to the control board 36, so that the control board 36 controls the first pole of the adapter interface 38, the external atomizing head 33 and the second pole of the adapter interface 38 to be connected to form a closed loop, so as to make the external atomizing head 33 work under power; if only the adapter interface 38 is connected with the power adapter after the water tank 31 is taken out, since the water tank 31 is not turned upside down, the control board 36 will not send a corresponding signal, and at this time the external atomizing head 33 will not work under power, so as to realize the external forced turning function of the humidifying module 30.

[0086] Please refer to FIG. 17 , which is a schematic diagram of the principle of the external forced turning operation of the humidifying module 30 of an embodiment. When the humidifying module 30 starts to be used, the state detection unit 34 judges whether the sensor 348 and the sensing piece 349 are aligned, if they are aligned, the second pole (for example, the negative pole) of the electrical connection piece 37 is connected to the built-in atomizing head 32 through the control board 36, and then it is judged whether the electrical connection piece 37 is in contact with the power supply piece to be powered on, if the electrical connection piece 37 is powered on, the built-in atomizing head 32 is operated. When the state detection unit 34 judges that the sensor 348 and the sensing piece 349 are not aligned, that is, they are misaligned with each other, the second pole (for example, the negative pole) of the adapter interface 38 is connected to the external atomizing head 33 through the control board 36, and then it is judged whether the adapter interface 38 is connected with the power adapter to be powered on, if the adapter interface 38 is powered on, the external atomizing head 33 is operated.

[0087] Please refer to FIG. 1 and FIG. 2 The present application also provides an air treatment device 100, which comprises a housing 10, a fan assembly 20 and a humidifying module 30. The housing 10 has an air inlet, an air outlet 14, and an air duct 15 which communicates the air inlet with the air outlet 14; the fan assembly 20 is arranged in the air duct 15; and the humidifying module 30 is detachably mounted in the air duct 15. The specific structure of the humidifying module 30 is referred to the above embodiments. Since the air treatment device 100 of the present application adopts all the technical solutions of the above embodiments, it has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0088] It should be noted that the air treatment device 100 can be a product itself, such as an air conditioner, an air purifier or an air sterilizer, or the air treatment device 100 can be applied to the above products as a component part of the products. For example, in the present embodiment, the air treatment device 100 can be applied to an air conditioner. In the air treatment device 100, the housing 10 has the air duct 15 formed therein, the housing 10 has the air inlet and the air outlet 14 which communicate with the air duct 15, and the fan assembly 20 is arranged in the air duct 15 and is used to guide the airflow from the air inlet to the air outlet 14 through the air duct 15. The fan assembly 20 can include, but is not limited to, a centrifugal fan, a cross-flow fan or an axial flow fan.

[0089] The air treatment device 100 of the present application comprises the humidifying module 30 which is detachably arranged in the air duct 15. When the humidifying module 30 is assembled in the air duct 15 for use, the humidifying module 30 sprays the humidifying solution towards the air duct 15, and the airflow in the air duct 15 can carry the atomized solution to the air outlet 14 of the air duct 15, so as to realize the humidifying function of the air treatment device 100. In addition, the air duct system of the air treatment device 100 can accelerate the diffusion and flow of the atomized solution, so as to realize the cooperative use of the humidifying module 30 and the air treatment device 100, and achieve the optimal humidifying effect. When the humidifying module 30 is used independently outside the air duct 15, the humidifying module 30 can spray the humidifying solution towards the external environment, and at this time the humidifying module 30 can be used as an independent humidifier.
