[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] Figure 1A and Figure 1B It is a three-dimensional diagram of the humidifier involved in the utility model.

[0027] The humidifier 100 is polygonal in shape as a whole, and includes a shell 1, an operating mechanism 2, a control mechanism 5, an atomizing mechanism 6 and a mist delivery and ejection mechanism. The shell 1 stores a liquid that can be atomized (at least one of the first liquid and the second liquid described below). The operating mechanism 2 is at least used to provide an operating interface for the user to operate the humidifier 100. At least a portion of the operating mechanism 2 is exposed to the outside of the shell 1. The control mechanism 5 is arranged in the shell 1 and is used to control the flow of liquid in the humidifier 100 and detect the remaining amount of liquid in the humidifier 100. When When the amount of residual liquid is less than a predetermined value, the control mechanism 5 controls the humidifier 100 to stop working, and the atomizing mechanism 6 is arranged in the shell 1, for atomizing the liquid stored in the humidifier 100; a part of the mist conveying and spraying mechanism is arranged in the shell 1, and the other part protrudes from the shell 1; specifically, the mist conveying and spraying mechanism includes a mist conveying component 4 and a mist spraying component 13 that are interconnected, the mist conveying component 4 is connected to the atomizing mechanism 6, and the mist spraying component 13 is used to convey the atomized mist to the spray outlet and spray it out.

[0028] The specific operation mode of the operating mechanism 2 can be a mechanical knob, button, etc., or a touch screen, or can be operated by the user through other interfaces via wireless communication. At the same time, the operating mechanism 2 displays the current status information of the humidifier 100. The following will be described using the mechanical operation of the operating mechanism 2 as an example. As shown in the figure, the operating mechanism 2 includes a control knob 21 and a power switch 22. The control knob 21 is used to control the atomization speed of the atomization mechanism 6.

[0029] The housing 1 includes an upper cover assembly 1a, a middle housing 1b, and a lower cover assembly 1c, which are connected in sequence. The middle housing 1b is located between the upper cover assembly 1a and the lower cover assembly 1c. Based on the posture of the humidifier 100 during normal use, the side where the operating mechanism 2 is exposed to the housing 1 is defined as the front, and the side opposite thereto is defined as the rear. The gravity direction of the humidifier 100 is downward, and the side opposite thereto is upward. When the user faces backward, the user's left is the left side of the humidifier 100, and the user's right is the right side of the humidifier 100. The front-to-back direction, the up-down direction, and the left-to-right direction intersect, and preferably, the front-to-back direction, the up-down direction, and the left-to-right direction are perpendicular to each other; the upper cover assembly 1a is located above the middle shell 1b, and the lower cover assembly 1c is located below the middle shell 1b. The middle shell 1b is used to store a first liquid that can be atomized. Commonly, the first liquid is water; preferably, the upper cover assembly 1a and the middle shell 1b, as well as the middle shell 1b and the lower cover assembly 1c are combined in a detachable manner, so that the user only needs to take out the middle shell 1b to replenish the first liquid.

[0030] In some embodiments, at least one of the upper cover assembly 1a and the middle shell 1b is made of a transparent material, so that the user can directly observe the internal components of the humidifier from the outside of the humidifier 100. This structure can enhance the user experience. More importantly, when at least the middle shell 1b is made of a transparent material, the user can more intuitively see the amount of the first liquid stored in the middle shell 1b. Thus, even if the humidifier 100 does not alarm, the user can replenish the first liquid in advance according to his or her own needs.

[0031] [Upper cover assembly]

[0032] Figure 2A This is an exploded schematic diagram of the humidifier involved in the present invention after the upper cover assembly and the handle are separated from the middle shell; Figure 2B It is a three-dimensional diagram of a mist aggregation component of a mist spray assembly in a humidifier involved in the present utility model; Figure 2C It is a three-dimensional diagram of the cover body of the upper cover assembly in the humidifier involved in the present invention.

[0033] The humidifier 100 also includes a mist spraying assembly 13 for spraying mist. The upper cover assembly 1a includes a cover body 12 and a frame body 11 that are combined with each other. The frame body 11 is also combined with the middle shell 1b. The combination method of the frame body 11 and the middle shell 1b and the combination method of the frame body 11 and the cover body 12 can be fixed or detachable, and the specific method can be welding, pasting, etc. In the humidifier 100 involved in this embodiment, the frame body 11 is set as a square body; the cover body 12 includes a first main body 120 and a first connecting portion 122 arranged on the first main body 120, and the first connecting portion 122 is used to connect the mist conveying assembly 4 and the mist spraying assembly 13.

[0034] As shown in the figure, the first body 120 has an upper surface 120a facing upward and a lower surface 120b facing downward. At least a portion of the mist spray assembly 13 is located above the upper surface 120a / upper cover assembly 1a. Preferably, the mist spray assembly 13 is arranged in the middle of the humidifier 100 in the left-right direction. More preferably, the mist spray assembly 13 is arranged in the middle of the humidifier 100 in the front-to-back direction. Overall, the projection of the mist spray assembly 13 on the upper cover assembly 1a is located in the middle of the upper cover assembly 1a. This design is not only beautiful but also improves the utilization rate of the mist. Furthermore, the upper surface 120a is configured as a downwardly concave curved surface. In this way, a recessed portion 121 for liquid flow is formed between the upper surface 120a and the mist spray assembly 13. The user can add the first liquid to the humidifier 100 through the recessed portion 121. The recessed portion can also prevent liquid from overflowing.

[0035] The mist ejection assembly 13 includes a mist aggregate 132 and a mist ejection member 131 that are coupled to each other. The mist aggregate 132 is detachably coupled to the first body 120. A mist ejection chamber 134 is also formed in the mist aggregate 132. The mist ejection member 131 is provided with at least one ejection port 133 that communicates with the mist ejection chamber 134. The size of the mist ejection chamber 134 gradually increases in an upward direction. This design helps slow the speed at which mist is ejected from the ejection port 133, preventing the mist from being ejected too far from the user and thus reducing the user experience. The mist aggregate 132 includes a second body 1321 and a first coupling member 1322 disposed on the second body 1321. The first coupling member 1322 is configured to couple with the first connecting portion 122 to allow mist in the mist delivery assembly 4 to enter the mist aggregate 132.

[0036] like Figure 2B As shown, the first coupling member 1322 includes a first protrusion 132a, a second protrusion 132b, a first connecting portion 132d, a first base 132i and a first coupling portion 132g, wherein the first protrusion 132a and the second protrusion 132b are both extended downward from the second main body 1321, and along the radial direction intersecting the up and down directions, the first protrusion 132a and the second protrusion 132b are spaced apart from each other, and a first coupling groove 132c is formed therebetween, the second protrusion 132b is located radially inside the first protrusion 132a, the first connecting portion 132d extends along the radial direction, and one end of the first connecting portion 132d is connected to the second protrusion 132b, and the other end is connected to the first base 132i, and the first coupling portion 132g is configured as an elastic arm extending downward from the first base 132i. For example, the first coupling member 1322 and the first connecting portion 122 can be coupled to each other by providing a protrusion on the elastic arm 132g.

[0037] Furthermore, the first connecting portion 132d is configured to be a plurality of portions arranged at intervals along the circumferential direction of the first coupling member 1322, and a first connecting hole 132h is formed between two adjacent first connecting portions 132d for the mist to pass through; preferably, the first coupling member 1322 also includes at least one guide arm 132f extending downward from the first connecting portion 132d. Similarly, the guide arm 132f is also configured to be elastically deformable to improve the coupling efficiency between the first coupling member 1322 and the first connecting portion 122. Along the circumferential direction of the first coupling member 1322, the elastic arms 132g and the guide arms 132f are arranged at intervals. More preferably, the elastic arms 132g and the guide arms 132f are both configured to be multiple.

[0038] like Figure 2A and Figure 2CAs shown, the first communicating portion 122 includes a first connecting plate 12a, a third protrusion 12b, a fourth protrusion 12c, a second base 12j and a second connecting portion 12i, wherein the first connecting plate 12a is connected to the first main body 120, the third protrusion 12b is formed to protrude upward from the first connecting plate 12a, and the fourth protrusion 12c is formed to protrude upward from the second base 12j. One end of the second connecting portion 12i is connected to the first connecting plate 12a, and the other end is connected to the second base 12j. Along the circumferential direction of the first communicating portion 122, multiple second connecting portions 12i are arranged at intervals, and a third communicating hole 12e is formed between two adjacent second connecting portions 12i. The fourth protrusion 12c penetrates in the up-down direction to form a fourth communicating hole 12f. The first connecting plate 12a is formed with a fifth communicating hole 12d that penetrates in the up-down direction. The fourth communicating hole 12f is used to be combined with the mist polymer 132, and the third communicating hole 12e is used to be opposite to the first communicating hole 132h in the up-down direction.

[0039] In some embodiments, the first base 132i is penetrated in the up-down direction to form a second connecting hole 132j. Along the up-down direction, the fourth connecting hole 12f is used to be opposite to the second connecting hole 132j ​​in the up-down direction. This can increase the flow space of the mist, so that more mist can enter the mist ejection cavity 134 faster, while also reducing the flow speed of the mist.

[0040] In some embodiments, the third connecting hole 12e and the first connecting hole 132h can also be staggered in the up and down directions, and only the fourth connecting hole 12f and the third connecting hole 132j ​​are opposite to each other in the up and down directions. In this way, the path for the mist to be transported upward becomes narrower, and accordingly, the transport speed of the mist can also be reduced.

[0041] When the first coupling member 1322 is coupled to the first communicating portion 122, the third protrusion 12b is used to be inserted into the first coupling groove 132c. At the same time, the elastic arm 132g enters the fourth communicating hole 12f. The first coupling member 1322 is clamped to the first communicating portion 122 through the protrusion provided on the elastic arm 132g. In the coupled state, the mist spraying assembly 13 can rotate freely relative to the shell 1, so that the user can adjust the position of the mist spraying assembly 13 according to needs; along the radial direction of the first communicating portion 122, the third communicating hole 12e is located radially outside the third protrusion 12b. The liquid entering the recessed portion 121 will not enter the third communicating hole 12e and the fourth communicating hole 12f, but will directly enter the following first storage chamber 1b1 from the fifth communicating hole 12d. Therefore, the user does not need to disassemble any components of the humidifier 100 to replenish the first liquid into the first storage chamber 1b1.

[0042] Furthermore, the first connecting portion 122 also includes a fifth protrusion 12h extending downward from the first connecting plate 12a and a sixth protrusion 12g extending downward from the first connecting plate 12a or the first main body 120, and the fifth connecting hole 2d is located between the fifth protrusion 12h and the sixth protrusion 12g; when the sixth protrusion 12g is extended downward from the first connecting plate 12a, the first connecting plate 12a is connected to the first main body 120, and when the sixth protrusion 12g is extended downward from the first main body 120, the first connecting plate 12a can be connected to both the first main body 120 and the sixth protrusion 12g.

[0043] [Handle assembly]

[0044] Figure 2D It is a three-dimensional diagram of the handle in the humidifier involved in the utility model.

[0045] like Figure 2A As shown, the handle assembly 1e includes a handle 1e0 and a fastener 1e4, wherein the handle 1e0 is rotatably arranged in the middle shell 1b, and the fastener 1e4 is used to combine with the handle 1e0 on the outside of the middle shell 1b. On the one hand, the fastener 1e4 can be used to protect the handle 1e0, and on the other hand, the fastener 1e4 also plays the role of decorating the humidifier 100. Therefore, in some embodiments, the fastener 1e4 may not be necessary.

[0046] The handle 1e0 includes a gripping portion 1e1, a third connecting portion 1e2, and a second coupling member 1e3 disposed on the third connecting portion 1e2. The second coupling member 1e3 is configured to be rotatably coupled to the middle housing 1b, and the buckle 1e4 is coupled to the second coupling member 1e3. When the humidifier 100 is in use, the handle 1e0 is rotated into the middle housing 1b. At this time, the gripping portion 1e1 is disposed substantially parallel to the left-right direction. Figure 2D As shown, the second coupling member 1e3 includes a rotating portion 1e31 protruding from the third connecting portion 1e2 and a restricted portion 1e32 arranged on the rotating portion 1e31. At the same time, a restricting portion for combining with the restricted portion 1e32 is provided on the middle shell 1b. By adjusting the structure of the restricting portion and the restricted portion 1e32, the gripping portion 1e3 can be maintained in a predetermined posture in the middle shell 1b; at the same time, the rotating portion 1e31 is also provided with a recessed mounting portion 1e33, and the fastener 1e4 can be inserted into the mounting portion 1e33. Conversely, the mounting portion 1e33 can also be provided to protrude from the rotating portion 1e31, and the fastener 1e4 is correspondingly recessed.

[0047] Furthermore, when the gripping portion 1e1 is parallel to the left-right direction, the gripping portion 1e1 has an upper side surface 1e11 and a lower side surface 1e12 that are opposite to each other in the vertical direction. At least the upper side surface 1e11 is parallel to the left-right direction. Preferably, the lower side surface 1e12 is further configured to be an arc shape with the middle portion in the left-right direction arched upward. More preferably, as shown in FIG. Figure 2D As shown, the gripping portion 1e1 also has an inner side surface 1e14, which faces the direction in which the third connecting portion 1e2 extends from the gripping portion 1e1. An adapting portion 1e13 recessed from the intersection is formed at the intersection of the lower side surface 1e12 and the inner side surface 1e14, making it easy for the user's hand to slide over the adapting portion 1e13 and grasp the gripping portion 1e1.

[0048] In other embodiments, the handle 1e0 may also be arranged outside the shell 1, preferably inside the shell 1.

[0049] The handle 1e0 in the present invention is disposed in the middle housing 1b, which has at least the following beneficial effects:

[0050] 1. There is no need to provide a handle on the outside of the housing 1 of the humidifier 100, which can improve the overall aesthetics of the humidifier 100;

[0051] 2. In the case of item 1, the overall volume of the humidifier 100 can also be reduced;

[0052] 3. When the user needs to add a large amount of the first liquid to the humidifier 100, the user can quickly do so by removing the upper cover assembly 1a and lifting the middle shell 1b by grabbing the handle 1e0.

[0053] [Middle shell]

[0054] Figure 3 This is an exploded schematic diagram of the humidifier involved in the present invention after being cut along the AA direction in FIG. 1 , with the seasoning box separated from the active housing and the control valve cover separated from the middle housing; Figure 4 This is a three-dimensional diagram of the humidifier involved in the present invention after the middle shell and the lower cover assembly are separated.

[0055] The middle shell 1b is formed into a hollow cylindrical shape open upward, including an integrally formed third body 1b10 and a bottom plate 1b2. The third body 1b10 and the bottom plate 1b2 enclose a first storage chamber 1b1 for storing the first liquid. Preferably, the third body 1b10 and the bottom plate 1b2 are formed as one piece, which can effectively prevent the first liquid from leaking from the gap between the third body 1b10 and the bottom plate 1b2 to the circuit board assembly 7 below the bottom plate 1b2. At least a portion of the mist delivery assembly 4 is arranged in the first storage chamber 1b1. Overall, the bottom plate 1b2 can be a regular square, circle, etc., or other irregular shapes.

[0056] like Figure 4 As shown, the middle shell 1b also includes a positioning column 1b3, a first mounting column 1b5 and a second mounting column 1b6 arranged on the base plate 1b2, wherein the first mounting column 1b5 is used to allow the third control component 53 described below to pass through, and the second mounting column 1b6 is used to allow the first control component 51 described below to pass through. Preferably, the positioning column 1b3, the first mounting column 1b5 and the second mounting column 1b6 are all set to be cylindrical, and the three are respectively set close to the corners of the base plate 1b2. In this way, by utilizing the positioning column 1b3, the first mounting column 1b5 and the second mounting column 1b6, the middle shell 1b can be accurately combined with the lower cover assembly 1c. More preferably, the diameter of the positioning column 1b3, the diameter of the first mounting column 1b5 and the diameter of the second mounting column 1b6 are different. This structure can ensure that the installation direction of the middle shell 1b relative to the lower cover assembly 1c will not be wrong, that is, there will be no problem of the middle shell 1b being installed in the front-to-back direction or the left-to-right direction.

[0057] In a deformable manner, the positioning column 1b3, the first mounting column 1b5 and the second mounting column 1b6 can also be set to an arc shape instead of a cylindrical shape as a whole, as long as the shapes of the three are utilized so that the middle shell 1b and the lower cover assembly 1c can be accurately combined and / or the above-mentioned reverse installation situation can be prevented from occurring.

[0058] like Figure 4 As shown, the operating mechanism 2 also includes an atmosphere light 23 arranged in the lower cover assembly 1c, and the bottom plate 1b2 is also provided with a receiving groove 1b7 for accommodating the atmosphere light 23. Preferably, the atmosphere light 23 is turned on or off by the knob 22, and can also be controlled by the knob 21 to change the variable or dim. Furthermore, the humidifier 100 also includes a second liquid release chamber 1b8 and a mixing chamber 1b9 recessed from the bottom plate 1b2 toward the first storage chamber 1b1, and the second liquid release chamber 1b8 and the mixing chamber 1b9 are connected through a sixth connecting hole 1b0.

[0059] [Mist delivery component]

[0060] The mist conveying assembly 4 includes a third base 40, a conveying pipe 41 and a discharge portion 42. The third base 40 is connected to the mixing chamber 1b9. The conveying pipe 41 extends in the up and down directions and is a cone-shaped body that gradually becomes smaller from bottom to top. The discharge portion 42 includes a seventh protrusion 421 and an eighth protrusion 422 connected to the conveying pipe 41. A second coupling groove 425 is formed between the seventh protrusion 421 and the eighth protrusion 422. When the upper cover assembly 1a is installed, the fifth protrusion 12h is combined with the second coupling groove 425. In this way, the mist flowing through the discharge portion 42 will continue to be guided to the upper cover assembly 1a without leakage.

[0061] Furthermore, the discharge portion 42 further includes a fourth connecting portion 424 and a fourth base portion 423 . One end of the fourth connecting portion 424 is connected to the eighth protrusion 422 , and the other end is connected to the fourth base portion 423 . Thus, the structural strength of the discharge portion 42 can be improved.

[0062] Continue as Figure 4 As shown, the mist delivery assembly 4 further includes an intermediate piece 43, the intermediate piece 43 includes a first portion 431 and a second portion 432, the two being connected via a seventh communicating hole 437, wherein the first portion 431 is used to allow the second liquid that has been volatilized or atomized to enter, and the second portion 432 is used to be opposite to the atomizing mechanism 6, so that the first liquid can directly enter the second portion 432 after being atomized. Furthermore, the intermediate piece 43 further includes a partition plate 436 provided in the second portion 432 and at least one communicating hole provided on the partition plate 436, and the third base 40 is opposite to the at least one communicating hole; specifically, as shown in FIG. Figure 4 As shown, the eighth connecting hole 433, the ninth connecting hole 434 and the tenth connecting hole 435 are all arranged on the partition plate 436, the diameter of the ninth connecting hole 434 is the largest, the diameter of the tenth connecting hole 435 is the second largest, and the diameter of the eighth connecting hole 433 is the smallest, and multiple eighth connecting holes 433 are arranged around the ninth connecting hole 434. Along the radial direction of the ninth connecting hole 434, the tenth connecting hole 345 is farther away from the ninth connecting hole 434 than the eighth connecting hole 433. On the one hand, this design can effectively capture the mist, and on the other hand, it makes the mist evenly distributed in the delivery pipe 41.

[0063] [Lower cover assembly]

[0064] Figure 5 This is a schematic exploded view of the lower cover assembly of the humidifier involved in the present invention, after the lower shell and the working shell are separated.

[0065] The lower cover assembly includes a lower shell 1c0 and an action shell 1f that are combined with each other. The action shell 1f is provided with an action space 1f1 that is recessed downward. The lower shell 1c0 is also provided with a accommodating space 1c3 that is recessed downward. The action shell 1f is accommodated by the accommodating space 1c3. The intermediate piece 43 is arranged in the action space 1f. Through the first control assembly 51 described below, the action space 1f1 can be intermittently connected to the first storage chamber 1b1. The first liquid is atomized in the action space 1f1. Therefore, the action space 1f1 can also be called a second storage chamber.

[0066] The lower cover assembly further includes a seasoning box 1d removably coupled to the active housing 1f, a seasoning box accommodating portion 1c1, and a flow guide chamber 1f2 communicating with the seasoning box accommodating portion 1c1. The flow guide chamber 1f2 communicates with the second liquid release chamber 1b8 via a flow guide port 1f3 disposed therein. The seasoning box 1d is used to hold fragrance, which can be a solid or a second liquid different from the first liquid. The seasoning box 1d has an upward-facing opening 1d1 that communicates with the flow guide chamber 1f2. The seasoning box 1d is also exposed through an exposure port 1c6 disposed in the lower housing 1c0.

[0067] The seasoning box accommodating portion 1c1 is provided with a guiding portion 1c2, and correspondingly, the seasoning box 1d is provided with a guided portion. Through the guidance of the guiding portion 1c2 and the guided portion, the seasoning box 1d can be smoothly installed toward the seasoning box accommodating portion 1c1 and smoothly taken out from the seasoning box accommodating portion 1c1.

[0068] Preferably, the lower surface 1c5 of the seasoning box accommodating portion 1c1 is sealed, so that the second liquid leaking from the guide cavity 1f2 will not flow into the circuit board assembly 7 arranged 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 with reference to the accompanying drawings.

[0070] In this embodiment, the control mechanism 5 includes at least a first control component 51, a second control component 52 and a third control component 53. The first control component 51 is used to control the connection and disconnection of the first storage chamber 1b1 and the second storage chamber 1f1. When the first control component 51 is opened, the first storage chamber 1b1 and the second storage chamber 1f1 are connected. When the first control component 51 is closed, the first storage chamber 1b1 and the second storage chamber 1f1 are disconnected. According to the amount of liquid in the second storage chamber 1f1, the second control component 52 is used to control the opening and closing of the first control component 51. According to the amount of liquid in the second storage chamber 1f1, the third control component 53 is used to control whether the humidifier 100 is working.

[0071] Specifically, the first control assembly 51 includes a control valve 511, a valve cover 513 and a third coupling member 512, wherein the control valve 511 allows liquid to flow from the first storage chamber 1b1 to the second storage chamber 1f1, but does not allow liquid to flow from the second storage chamber 1f1 to the first storage chamber 1b1; through the third coupling member 512, commonly, the control valve 511 can be set as a one-way valve, the valve cover 513 is detachably combined with the control valve 511, and the valve cover 513 includes a fourth body 513a, a force receiving portion 513b and a coupled member 513c, wherein the force receiving portion 513b is formed to protrude upward from the fourth body 513a for grasping by a user, and the coupled member 513c is formed to protrude radially outward from the fourth body 513a, and the third coupling member 512 includes a fourth body 513a, a force receiving portion 513b and a coupled member 513c, wherein the force receiving portion 513b is formed to protrude upward from the fourth body 513a for grasping by a user, and the coupled member 513c is formed to protrude radially outward from the fourth body 513a, and the third coupling member 512 includes a fourth body 513a, a force receiving portion 513b and a coupled member 513c, The fifth body 512d, the inlet 512a, the limiting groove 512b and the limiting protrusion 512c, the fifth body 512d is arranged along the circumferential direction of the control valve 511, the inlet 512a, the limiting groove 512b and the limiting protrusion 512c are all arranged on the fifth body 512d. When the valve cover 513 is installed, the coupled part 513c is aligned with the inlet 512a, and then the valve cover 513 is rotated according to the position of the limiting groove 512b so that the coupled part 513c enters the limiting groove 512b to realize the combination of the valve cover 513 and the third coupling part 512. In this way, the coupled part 513c is limited by the limiting protrusion 512c in the up and down directions. When the valve cover 513 is rotated in the opposite direction, the valve cover 513 is disengaged from the third coupling part 512.

[0072] Preferably, the valve cover 513 further comprises an abutting protrusion 513d provided on the coupled member 513c, and the valve cover 513 and the control valve 511 can be more closely abutted by the abutting protrusion 513d and the limiting protrusion 512c; more preferably, the surface 513e on which the abutting protrusion 513d is provided is provided as an inclined plane, and the inclined direction of the surface 513e is such that, along the coupling direction between the valve cover 513 and the third coupling member 512, the distance between the surface 513e and a certain fixed point in the force receiving portion 513b in the vertical direction gradually becomes smaller, thereby enabling the valve cover 513 to be more smoothly coupled to the third coupling member 512; Figure 3 As shown, when the abutting protrusion 513d is arranged at a non-end 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 scoop that can rotate around a predetermined axis. The scoop 52 is configured as a lever. One end of the scoop 52 is made of a material with a density lower than that of the first liquid and is called a floating part. The other end is used to act on the control valve 511 and is called an action part. When the amount of liquid in the second storage chamber 1b1 is large, the scoop 52 / floating part floats up and the action part moves 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 action part gradually approaches the control valve 511. When the liquid in the second storage chamber 1f1 drops below the first threshold, the action part opens the control valve 511, and the first liquid in the first storage chamber 1b1 is replenished into the second storage chamber 1f1. As the amount of liquid in the second storage chamber 1f1 increases, the scoop 52 gradually floats again, and the action part moves away from the control valve 511 again. The control valve 511 closes again, and the first liquid in the first storage chamber 1b1 stops being replenished into the second storage chamber 1f1.

[0074] It can be seen that the scoop 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 scoop 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 component 7 to control whether the humidifier 100 is working. When the amount of liquid in the second storage chamber 1f1 decreases to below the second threshold value, the third control component 53 interacts with the circuit board component 7 to stop the humidifier 100 and issue an alarm, for example, by issuing a sound signal through a buzzer set in the humidifier 100, or issuing a light signal through a flashing indicator light or a light indicator light going out set in the humidifier 100; specifically, Figure 4 and Figure 5 As shown, a magnetic part 531 is provided in the third control component 53, and correspondingly, an electromagnetic relay 54 is provided in the circuit board component 7. When the amount of liquid in the second storage chamber 1f1 is 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 toward 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 component 7 can also be that the circuit board component 7 controls whether the humidifier 100 is working by detecting / sensing the gravity of the third control component 53. It should be understood that the third control component 53 should not be limited to being set as the above-mentioned electromagnetic part 531 or using its gravity detection, and other methods that can move as the amount of liquid in the second storage chamber 1f1 changes can also be adopted, as long as the liquid amount can be detected and the operation of the humidifier 100 can be controlled through the circuit component 7.

[0076] Conversely, when the amount of liquid in the second storage chamber 1f1 gradually increases, the third control component 53 moves away from the circuit board component 7 again. At this time, the circuit board component 7 controls the humidifier 100 to continue working again. In an optional manner, when the humidifier 100 is working, the indicator light is always on, or flashes at the same frequency.

[0077] It can be seen that the third control component 53 can also be regarded as a liquid quantity detection component. Preferably, the active shell 1f also includes a detection channel 1f5 arranged on the lower side plate 1f4, and the third control component 53 is arranged in the detection channel 1f5, which can improve the detection accuracy of the third control component 53; more preferably, the detection channel 1f5 is recessed downward from the upward surface of the lower side plate 1f4, and the detection channel 1f5 is also connected to the atomization mechanism 6, so as to ensure that the liquid in the second storage chamber 1f1 can enter the atomization device 6 through the detection channel 1f5, so as to further improve the detection accuracy of the third control component 53.

[0078] The humidifier 100 in this embodiment is configured such that, in the vertical direction, the electromagnetic relay 54 and the magnetic member 531 are only electrically connected to each other when the magnetic member 531 is within a predetermined height range. 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, if the user has finished adding the first liquid to the humidifier 100 but has not yet closed 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 usage requirements. It is expected to be used, but there is also a 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 part 531, so that the height of the magnetic part 531 drops to within the predetermined height range, and the circuit board assembly 7 is connected, can the humidifier 100 start working; as the humidifier 100 is used, the first liquid gradually decreases, and the floating height of the magnetic part 531 gradually decreases. When the floating height of the magnetic part 531 is lower than the predetermined height range, the humidifier 100 will stop working, thereby preventing damage to the humidifier 100.

[0079] Specifically, in addition to interacting with the electromagnetic relay 54, the electromagnetic component 531 can also cooperate with the reed switch or the 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 component 531, thereby limiting the floating height of the magnetic component 531, so that the magnetic component 531 returns to the predetermined height range, so that the magnetic component 531 and the electromagnetic relay 54 can better contact and cooperate to conduct the circuit; it can be seen that setting the magnetic component 531 within the predetermined height range to work is not only beneficial to protecting the humidifier 100, but also beneficial to improving the user experience and safety of use. Furthermore, the second control member 52 extends generally in the front-to-back direction, and in the left-to-right direction, the second control member 52 and the third control assembly 53 are respectively located on both sides of the second storage chamber 1f1, and at least a portion of the atomization device 6 is located in the middle of the second storage chamber 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 portion of the atomization device 6. Such an arrangement is conducive 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 guide chamber 1f2 / seasoning box 1d are connected at the projection point of the lower side plate 1f4 to form a triangle, and at least a portion of the atomization device 6 is located within the area covered by the triangle. This design makes the spatial layout within the second storage chamber 1f1 more reasonable, is more conducive to the flow of liquid in the second storage chamber 1f1, and prevents excessive residual liquid in the second storage chamber 1f1.

[0080] like Figure 4 As shown, the working 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 conveying and spraying mechanism including the mist conveying assembly 4 and the mist spraying assembly 13 is arranged above the lower side plate 1f4, that is, the mist 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 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 described below are separated by the side plate of the seasoning box, which can also prevent liquid from leaking to the circuit board.

[0081] like Figure 5 As shown, the humidifier 100 also includes a fan 1d2 arranged between the active shell 1f and the lower shell 1c0. The fan 1d2 is used to accelerate the volatilization speed of the second liquid in the seasoning box 1d. Generally, the second liquid is aromatherapy. Through the fan 1d2, the first liquid can be atomized and fully mixed with the second liquid to further enhance the user experience.

[0082] Preferably, the humidifier 100 also includes at least one anti-slip pad 1g arranged under the lower shell 1c0. Optionally, the anti-slip pad 1g can be arranged in the middle of the downward-facing surface of the lower shell 1c0, or at the corner of the downward-facing surface of the lower shell 1c0; more preferably, four anti-slip pads 1g are provided, and the four anti-slip pads 1g are respectively arranged at the four corners of the downward-facing surface of the lower shell 1c0.
