The flavor cartridge 1d is used to accommodate an aroma, which can be a solid or a second liquid different from the first liquid, and has an upwardly facing opening 1d1 in communication with the flow guide cavity 1f2, while the flavor cartridge 1d is also exposed from an exposure opening 1c6 provided in the lower housing 1c0.

[0067] The flavor cartridge accommodating portion 1c1 is provided with a guide portion 1c2, and correspondingly, the flavor cartridge 1d is provided with a guided portion, through the guidance of the guide portion 1c2 and the guided portion, the flavor cartridge 1d can be smoothly installed towards the flavor cartridge accommodating portion 1c1 and smoothly taken out from the flavor cartridge accommodating portion 1c1.

[0068] Preferably, the lower surface 1c5 of the flavor cartridge accommodating portion 1c1 is closed, so that the second liquid leaked from the flow guide cavity 1f2 will not flow into the circuit board assembly 7 provided in the accommodating space 1c3, thereby reducing the risk of short circuit of the circuit board assembly 7.

[0069] The structure of the control mechanism 5 will be described below in conjunction with the accompanying drawings.

[0070] In the present embodiment, the control mechanism 5 at least comprises a first control assembly 51, a second control assembly 52 and a third control assembly 53, the first control assembly 51 is used to control the communication and disconnection of the first storage cavity 1b1 and the second storage cavity 1f1, when the first control assembly 51 is opened, the first storage cavity 1b1 and the second storage cavity 1f1 are in communication, when the first control assembly 51 is closed, the first storage cavity 1b1 and the second storage cavity 1f1 are disconnected; the second control assembly 52 is used to control the opening and closing of the first control assembly 51 according to the amount of liquid in the second storage cavity 1f1; the third control assembly 53 is used to control whether the humidifier 100 works according to the amount of liquid in the second storage cavity 1f1.

[0071] Specifically, the first control assembly 51 comprises a control valve 511, a valve cover 513 and a third coupling member 512, the control valve 511 allows liquid to flow from the first storage cavity 1b1 to the second storage cavity 1f1, but does not allow liquid to flow from the second storage cavity 1f1 to the first storage cavity 1b1; the control valve 511 can be provided as a one-way valve through the third coupling member 512, the valve cover 513 is detachably coupled with the control valve 511, the valve cover 513 comprises a fourth main body 513a, a force receiving part 513b and a coupled part 513c, wherein the force receiving part 513b is formed upwardly protruding from the fourth main body 513a for a user to hold, and the coupled part 513c is formed radially outwardly protruding from the fourth main body 513a, the third coupling member 512 comprises a fifth main body 512d, an entering port 512a, a limiting groove 512b and a limiting protrusion 512c, the fifth main body 512d is arranged along the circumferential direction of the control valve 511, the entering port 512a, the limiting groove 512b and the limiting protrusion 512c are all arranged on the fifth main body 512d, when the valve cover 513 is installed, the coupled part 513c is aligned with the entering port 512a, then according to the position of the limiting groove 512b, the valve cover 513 is rotated so that the coupled part 513c enters the limiting groove 512b to realize the coupling of the valve cover 513 and the third coupling member 512, in this way, the coupled part 513c is limited by the limiting protrusion 512c in the up-down direction, when the valve cover 513 is rotated in the opposite direction, the valve cover 513 is decoupled from the third coupling member 512.

[0072] Preferably, the valve cover 513 further comprises an abutting protrusion 513d arranged on the coupled part 513c, through the abutting of the abutting protrusion 513d and the limiting protrusion 512c, the valve cover 513 can be more closely abutted with the control valve 511; more preferably, the surface 513e where the abutting protrusion 513d is arranged is arranged as an inclined surface, the inclined direction of the surface 513e is along the coupling direction of the valve cover 513 and the third coupling member 512, and the distance between the surface 513e and a fixed point in the force receiving part 513b in the up-down direction gradually decreases, so that the valve cover 513 can be more smoothly coupled with the third coupling member 512; as shown in Figure 3 When the abutting protrusion 513d is arranged at a non-terminal position of the surface 513e, the surfaces on both sides of the abutting protrusion also have the above-mentioned inclined direction.

[0073] The second control component 52 is preferably a water ladle rotatable around a predetermined axis, and the water ladle 52 is integrally arranged in a lever shape, one end of which is made of a material with a density less than that of the first liquid and is called a floating part, and the other end is used to act on the control valve 511 and is called an acting part. When the amount of liquid in the second storage chamber 1f1 is relatively large, the water ladle 52 / the floating part floats, and the acting part is away from the control valve 511. At this time, the control valve 511 is closed. As the liquid in the second storage chamber 1f1 is consumed, the floating part gradually descends, and the acting part gradually approaches the control valve 511. When the liquid in the second storage chamber 1f1 falls below the first threshold value, the acting part opens the control valve 511, and the first liquid in the first storage chamber 1b1 is replenished to the second storage chamber 1f1. As the amount of liquid in the second storage chamber 1f1 increases, the water ladle 52 gradually floats again, and the acting part is away from the control valve 511 again, and the control valve 511 is closed again, and the replenishment of the first liquid in the first storage chamber 1b1 to the second storage chamber 1f1 stops.

[0074] It can be seen that the water ladle 52 can be summarized as having a first position and a second position. In the first position, the control valve 511 is in a closed state, and the first liquid in the first storage chamber 1b1 cannot flow to the second storage chamber 1f1. In the second position, the control valve 511 is opened by the water ladle 52, and the first liquid in the first storage chamber 1b1 can flow to the second storage chamber 1f1.

[0075] The third control component 53 is used to interact with the circuit board assembly 7 to control whether the humidifier 100 works. When the amount of liquid in the second storage chamber 1f1 decreases below the second threshold value, the third control component 53 interacts with the circuit board assembly 7 to make the humidifier 100 stop working and issue an alarm, for example, issuing an audible signal through a buzzer arranged in the humidifier 100, or issuing a light signal through a flashing or extinguished indicator light arranged in the humidifier 100, etc. Specifically, as shown in Figure 4 and Figure 5 The third control component 53 is provided with a magnetic part 531, and correspondingly, the circuit board assembly 7 is provided with an electromagnetic relay 54. When the amount of liquid in the second storage chamber 1f1 is relatively large, the magnetic part 531 floats. As the amount of liquid in the second storage chamber 1f1 gradually decreases, the magnetic part 531 gradually moves towards the lower side plate 1f4 until the magnetic part 531 can interact with the electromagnetic relay 54. In other embodiments, the interaction between the third control component 53 and the circuit board assembly 7 can also be that the circuit board assembly 7 controls whether the humidifier 100 works by detecting / inducing the gravity of the third control component 53. It should be understood that the third control component 53 should not be limited to being arranged as the above-mentioned electromagnetic part 531 or using its gravity detection, but can also use other ways that can move with the change of the amount of liquid in the second storage chamber 1f1, as long as the amount of liquid can be detected and the working of the humidifier 100 can be controlled by the circuit assembly 7.

[0076] Conversely, when the liquid amount in the second storage cavity 1f1 gradually increases, the third control assembly 53 again moves away from the circuit board assembly 7, at this time, the circuit board assembly 7 again controls the humidifier 100 to continue to work, in an optional mode, when the humidifier 100 works, the indicator light is always on, or flashes at the same frequency.

[0077] It can be seen that the third control assembly 53 can also be regarded as a liquid amount detection member, preferably, the acting shell 1f further comprises a detection channel 1f5 arranged on the lower side plate 1f4, and the third control assembly 53 is arranged in the detection channel 1f5, so that the detection accuracy of the third control assembly 53 can be improved; more preferably, the detection channel 1f5 is recessed downward from the surface of the lower side plate 1f4 facing upward, and the detection channel 1f5 further communicates with the atomization mechanism 6, so that the liquid in the second storage cavity 1f1 can all enter the atomization device 6 through the detection channel 1f5, so as to further improve the detection accuracy of the third control assembly 53.

[0078] The humidifier 100 in the embodiment is arranged to be along the up-down direction, only when the magnetic member 531 is within a predetermined height range, the electromagnetic relay 54 and the magnetic member 531 are mutually conductive, when the first liquid is sufficient, the height of the magnetic member 531 floating will exceed the predetermined height, at this time, the circuit board assembly 7 is disconnected, and the humidifier 100 does not work, for example, the user has just replenished the first liquid into the humidifier 100, but has not yet covered the middle shell 1b to the lower cover assembly 1c, if the humidifier 100 starts to work at this time, it will not meet the user's use expectation, and there is also the risk of electric shock, only when the middle shell 1b is covered to the lower cover assembly 1c, the first mounting column 1b5 presses the magnetic member 531, so that the height of the magnetic member 531 decreases to within the predetermined height range, the circuit board assembly 7 is connected, and the humidifier 100 can start to work; with the use of the humidifier 100, the first liquid gradually decreases, the height of the magnetic member 531 floating gradually decreases, when the height of the magnetic member 531 floating is lower than the predetermined height range, the humidifier 100 will stop working, so as to prevent the humidifier 100 from being damaged.

[0079] Specifically, the electromagnetic member 531 can interact with the electromagnetic relay 54, and can also be matched with a dry Reed or Hall sensor to conduct the circuit; the first mounting column 1b5 passes through the electromagnetic relay 54, and when the first liquid is sufficient, the first mounting column 1b5 abuts against the magnetic member 531, thereby limiting the floating height of the magnetic member 531, so that the magnetic member 531 returns to the predetermined height range, thereby making the magnetic member 531 better contact the electromagnetic relay 54 to conduct the circuit. It can be seen that the magnetic member 531 is arranged in the predetermined height range to work, which not only helps to protect the humidifier 100, but also helps to improve the user's use experience and use safety.

[0080] Further, the second control member 52 extends in the front-rear direction, and in the left-right direction, the second control member 52 and the third control assembly 53 are respectively located on both sides of the second storage cavity 1f1, and at least a part of the atomization device 6 is located in the middle of the second storage cavity 1f1, that is, the second control member 52 and the third control assembly 53 are respectively located on the left and right sides of at least a part of the atomization device 6, which is beneficial to the user to quickly clean the atomization device 6; further, the center of the first control member 51, the center of the third control assembly 53, and the center of the flow guide cavity 1f2 / seasoning box 1d form a triangle at the projection point of the lower side plate 1f4, and at least a part of the atomization device 6 is located in the area covered by the triangle. This design makes the space layout in the second storage cavity 1f1 more reasonable, and is more conducive to the flow of liquid in the second storage cavity 1f1, preventing the amount of residual liquid in the second storage cavity 1f1 from being too large.

[0081] As shown in Figure 4 , the action shell 1f has a lower side plate 1f4 located below, the circuit board assembly 7 is arranged between the lower side plate 1f4 and the lower shell 1c0, and the mist body conveying and spraying mechanism including the mist body conveying assembly 4 and the mist body spraying assembly 13 is arranged above the lower side plate 1f4, that is, the mist body conveying and spraying mechanism and the circuit board assembly 7 are separated by the lower side plate 1f4, so that even if liquid leaks from the mist body conveying and spraying mechanism to the lower side plate 1f4, the circuit board assembly 7 will not be affected. At the same time, the fan 1d2 and the circuit board assembly 7 are separated by the side plate of the seasoning box, which can also prevent liquid from leaking to the circuit board.

[0082] As shown in Figure 5 , the humidifier 100 further comprises a fan 1d2 arranged between the action shell 1f and the lower shell 1c0, and the fan 1d2 is used to accelerate the evaporation speed of the second liquid in the seasoning box 1d. Generally, the second liquid is aromatherapy, and through the fan 1d2, the first liquid can be fully mixed with the second liquid after being atomized, so as to further improve the user's use experience.

[0083] Preferably, the humidifier 100 further comprises at least one anti-skid pad 1g arranged below the lower shell 1c0, and optionally, the anti-skid pad 1g can be arranged in the middle of the surface of the lower shell 1c0 facing downward, or arranged at the corner of the surface of the lower shell 1c0 facing downward; more preferably, the anti-skid pad 1g is arranged as four, and the four anti-skid pads 1g are arranged at the four corners of the surface of the lower shell 1c0 facing downward, respectively.
