[0002] A humidifier is a household appliance that can increase indoor humidity. As people's requirements for living standards have become higher and higher in recent years, the demand for humidifiers has also been increasing year by year.

[0003] To monitor the water level in a humidifier, a water level alarm is typically installed. Current water level alarms often utilize a float and switch. The float rises and falls with the water level, while the switch opens and closes in response to the float's movement, thus providing an alarm. However, in existing technologies, the process of shifting the switch components driven by the float can cause misalignment, increasing the overall humidifier failure rate and causing inconvenience for users.

[0058] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0059] like Figure 1As shown, the liquid level monitoring assembly of the embodiment of the present invention includes a fixed assembly 10 and a floating assembly 20. The floating assembly 20 is placed on the liquid and floats as the liquid level changes. The floating assembly 20 and the fixed assembly 10 are arranged relative to each other in the floating direction of the floating assembly 20.

[0060] For example, Figure 1 As shown, the structure enclosed by the upper dashed box can be considered as the fixed assembly 10, and the structure enclosed by the lower dashed box can be considered as the floating assembly 20. The fixed assembly 10 can be fixedly installed in a corresponding position and remain in place during use. The floating assembly 20 can be placed in a liquid such as water and directly below the fixed assembly 10. The floating assembly 20 has a certain buoyancy. During use, the floating assembly 20 can float up and down due to the buoyancy as the liquid level changes.

[0061] The fixed assembly 10 and the floating assembly 20 are configured to generate an induction signal to monitor the liquid level. For example, a magnetic induction element and a magnet can be disposed within the fixed assembly 10 and the floating assembly 20, respectively. When the position of the floating assembly 20 relative to the fixed assembly 10 changes, the magnetic field sensed by the magnetic induction element changes. This change generates a magnetic induction signal, thereby satisfying the need for monitoring the liquid level.

[0062] The floating assembly 20 and the fixed assembly 10 are plugged together to prevent misalignment when the floating assembly 20 and the fixed assembly 10 move toward each other. For example, the floating assembly 20 may be provided with a slot 27, and the fixed assembly 10 may be provided with a plug-in portion. As the floating assembly 20 floats up and down relative to the fixed assembly 10, the plug-in portion can be plugged into the slot 27, thereby calibrating the alignment accuracy of the floating assembly 20 and the fixed assembly 10, thereby preventing misalignment that may increase the overall failure rate.

[0063] It should be noted that the liquid level monitoring component of the embodiment of the present invention can be applied to household appliances such as humidifiers, sweeping robots, and atomizers, and of course can also be applied to other equipment that requires liquid level monitoring.

[0064] The liquid level monitoring component of the embodiment of the present invention avoids the situation where the floating component 20 is skewed or offset during movement by designing the floating component 20 and the fixed component 10 to be plug-in compatible, thereby ensuring the alignment precision and accuracy of the floating component 20 and the fixed component 10 in the process of generating the sensing signal, thereby avoiding the high failure rate in the monitoring process caused by alignment offset, and improving the user experience.

[0065] In some embodiments, as Figure 1As shown, the fixed component 10 includes a mounting member 2 and a first sensing member 3, and the floating component 20 includes a float 1 and a second sensing member 4. At least one of the mounting member 2 and the first sensing member 3 is plugged into and matched with at least the other of the float 1 and the second sensing member 4.

[0066] For example, one of the mounting member 2 and the floating body 1 may be provided with a slot 27, and the other may be provided with a plug-in portion, and the plug-in cooperation between the mounting member 2 and the floating body 1 can realize the precise alignment of the floating assembly 20 during the up and down floating process.

[0067] In other embodiments, one of the first sensing member 3 and the second sensing member 4 may be provided with a slot 27, and the other may be provided with a plug-in portion, and alignment during relative movement can be achieved through the plug-in cooperation of the first sensing member 3 and the second sensing member 4.

[0068] In some other embodiments, one of the mounting member 2 and the second sensing member 4 may be provided with a slot 27, and the other may be provided with a plug-in portion, and alignment during relative movement can be achieved through the plug-in cooperation between the mounting member 2 and the second sensing member 4.

[0069] In some other embodiments, one of the float 1 and the first sensing member 3 may be provided with a slot 27, and the other may be provided with a plug-in portion, and alignment during relative movement can be achieved through the plug-in cooperation between the float 1 and the first sensing member 3.

[0070] In this way, the plug-in matching forms of the fixed component 10 and the floating component 20 can be enriched, that is, the plug-in matching forms of the fixed component 10 and the floating component 20 can be selectively designed according to actual needs to meet the usage needs of different product types.

[0071] In some embodiments, as Figure 1 As shown, the float 1 is placed in the liquid and floats up and down as the liquid level changes, and the mounting member 2 is provided above the float 1. Figure 1 As shown, the float 1 as a whole can be a structure with a larger bottom and a smaller top. The float 1 can be formed by processing a material with a lower density such as plastic. When in use, the float 1 can be placed directly in a liquid such as water. Since the buoyancy of the float 1 is greater than the gravity, the float 1 can float up and down with the up and down changes of the liquid.

[0072] like Figure 1 As shown, the mounting member 2 can be disc-shaped as a whole, and the mounting member 2 can be fixed at the corresponding position of the equipment, such as Figure 2 As shown, the mounting member 2 can be located substantially above the floating body 1, and the mounting member 2 can be arranged substantially coaxially with the floating body 1. The arrangement of the mounting member 2 can provide an installation position for the installation of the first mounting member 2.

[0073] The first sensing element 3 is provided on the mounting element 2 , and the second sensing element 4 is provided on the floating body 1 . The first sensing element 3 and the second sensing element 4 are used to generate sensing signals to realize height monitoring of the liquid level.

[0074] For example, Figure 1 and Figure 2 As shown, the first sensing member 3 can be fixed to the mounting member 2 by means of snap connection, fastening, bonding, etc., and the second sensing member 4 can be fixed to the top of the floating body 1 by means of snap connection, fastening, bonding, etc. It should be noted that magnetic induction, photoelectric induction, etc. can be generated between the first sensing member 3 and the second sensing member 4, and such induction can change with the relative displacement of the first sensing member 3 and the second sensing member 4.

[0075] During use, since the position of the mounting member 2 remains unchanged, the first sensing member 3 remains stationary. Since the float 1 rises and falls with the liquid level, the second sensing member 4 also moves up and down synchronously, thereby enabling the distance between the first sensing member 3 and the second sensing member 4 to be adjusted. This adjustment allows the aforementioned sensing to be varied and different signals to be output. The different output signals can then be used to monitor the liquid level, thereby meeting the need for an alarm when the liquid level is low.

[0076] One of the mounting member 2 and the second sensing member 4 is provided with a recess 26 , and the other is provided with a protrusion 41 . The protrusion 41 is used to be plugged into the recess 26 to prevent the first sensing member 3 and the second sensing member 4 from deviating when they move toward each other.

[0077] For example, Figure 2 As shown, the recess 26 can be provided on the bottom side of the mounting member 2. The recess 26 can be a groove. The first sensing member 3 can be provided directly above the recess 26. A portion of the second sensing member 4 can constitute a protrusion 41. When the float 1 and the second sensing member 4 move upward under the action of the liquid, the protrusion 41 can be inserted into the recess 26. The limiting effect of the protrusion 41 and the recess 26 can prevent the second sensing member 4 from being easily skewed and deviated when approaching the first sensing member 3, thereby ensuring the stability of the alignment of the first sensing member 3 and the second sensing member 4 when the liquid level is high.

[0078] The liquid level monitoring component of the embodiment of the present invention provides a recess 26 and a protrusion 41 on the mounting member 2 and the second sensing member 4. The plug-in cooperation of the recess 26 and the protrusion 41 can play a guiding and limiting role, thereby avoiding the second sensing member 4 from tilting or deviating during movement, ensuring the alignment precision and accuracy of the first sensing member 3 and the second sensing member 4, and thus avoiding a high failure rate during the monitoring process, thereby improving the user experience.

[0079] Secondly, compared with the existing technology that uses mechanical mechanisms to transmit signals, the non-contact sensing cooperation of the first sensing element 3 and the second sensing element 4 facilitates the realization of isolation protection, thereby avoiding situations where water vapor and the like can easily cause rust, damage, etc., which is conducive to simplifying the structure and also ensures stability in long-term use.

[0080] In some embodiments, as Figure 1 As shown, the fixing assembly includes a cover 5, which is arranged on the mounting member 2, and the first sensing member 3 is arranged between the cover 5 and the mounting member 2. For example, the cover 5 can be disc-shaped, and the cover 5 can be fixed to the mounting member 2 by means of snap connection, fastening with fasteners, threaded assembly, etc. After installation, an independent chamber can be enclosed between the cover 5 and the mounting member 2, and the independent chamber can be a sealed chamber. The first sensing member 3 can be located in the sealed chamber. The additional cover 5 can achieve a shielding and protective effect on the first sensing member 3, further prevent the first sensing member 3 from entering with water vapor, and improve the waterproof sealing performance.

[0081] In some embodiments, a limiting groove 21 is provided on the top side of the mounting member 2, and at least a portion of the first sensing member 3 is embedded in the limiting groove 21. Figure 1 As shown, the limiting groove 21 can be a circular groove and can be located at the center of the mounting member 2, with the notch of the limiting groove 21 facing upward. During assembly, a portion of the first sensing member 3 can be directly inserted into the limiting groove 21, thereby enhancing the limiting effect on the first sensing member 3 and the stability of the structure, and preventing the first sensing member 3 from easily shifting when the mounting member 2 is subjected to floating impact from the second sensing member 4.

[0082] In some embodiments, the mounting member 2 is provided with an assembly groove 22 , the limiting groove 21 is located in the assembly groove 22 , the first sensing member 3 is assembled in the assembly groove 22 , and at least a portion of the cover 5 is embedded in the assembly groove 22 .

[0083] For example, Figure 1 As shown, the assembly groove 22 can be a circular groove, the radial dimension of the assembly groove 22 is larger than the radial dimension of the above-mentioned limiting groove 21, the assembly groove 22 is also located on the top side of the mounting member 2, and the notch of the assembly groove 22 is also arranged upward. The limiting groove 21 can be provided on the bottom wall of the assembly groove 22.

[0084] After the first sensing member 3 is embedded and assembled in the above-mentioned limiting groove 21, the cover body 5 can be installed on the mounting member 2. During assembly, the cover body 5 as a whole can be embedded in the above-mentioned assembly groove 22, thereby improving the limiting constraint effect between the cover body 5 and the mounting member 2 on the one hand, and avoiding the situation where the cover body 5 protrudes from the upper side of the mounting member 2 on the other hand, ensuring the flatness above the mounting member 2, and thus facilitating the installation arrangement of other structures such as fan blades 62.

[0085] In some embodiments, the cover 5 is provided with a first snap portion 51 , and the inner groove wall of the assembly groove 22 is provided with a second snap portion 24 . The first snap portion 51 and the second snap portion 24 are snap-fitted and assembled to connect the cover 5 and the mounting member 2 .

[0086] For example, Figure 1 As shown, the first snap-fit ​​portion 51 can be integrally formed on the outer circumference of the cover 5 by injection molding. A plurality of first snap-fit ​​portions 51 can be provided, and the plurality of first snap-fit ​​portions 51 can be arranged at intervals along the circumference of the cover 5. A plurality of second snap-fit ​​portions 24 can be provided on the inner circumferential wall of the assembly groove 22, and the plurality of second snap-fit ​​portions 24 can be arranged at intervals along the circumference of the assembly groove 22.

[0087] During assembly, multiple first snap-fit ​​portions 51 can be respectively engaged with multiple second snap-fit ​​portions 24, thereby realizing the detachable assembly of the cover body 5 and the mounting member 2, improving the convenience of installation and disassembly, and providing convenience for subsequent inspection and maintenance.

[0088] In some embodiments, the mounting member 2 is provided with a wire groove 25 for passing wires. The wire groove 25 extends radially along the mounting member 2 and communicates with the assembly groove 22 . The cover body 5 is provided with an extension portion 52 , which is embedded in the wire groove 25 .

[0089] For example, Figure 1 As shown, the wire groove 25 can be a rectangular long groove, which can be provided on the top side of the mounting member 2 by injection molding. The wire groove 25 extends radially along the mounting member 2. The inner end of the wire groove 25 can be connected to the above-mentioned assembly groove 22, and the outer end of the wire groove 25 can pass through the outside of the mounting member 2. The extension portion 52 can be integrally formed on the outer circumference of the cover body 5, and the extension portion 52 can be long and extend radially along the cover body 5.

[0090] During assembly, the wires of the first sensing element 3 can be laid in the wire groove 25, and the extension part 52 can block the slot of the wire groove 25, thereby facilitating the laying of the wires of the first sensing element 3, and the extension part 52 can also provide shielding and protection for the wires.

[0091] In some embodiments, the mounting member 2 is provided with a columnar portion 23 , and the first sensing member 3 is provided with an ear portion 31 . The first sensing member 3 is mounted on the mounting member 2 via a fastener, and the fastener passes through the ear portion 31 and is connected to the columnar portion 23 .

[0092] For example, Figure 1 As shown, only one cylindrical portion 23 may be provided, and the cylindrical portion 23 may be a threaded column. The cylindrical portion 23 may be located adjacent to the aforementioned retaining groove 21. The first sensing element 3 may be integrally formed with an ear portion 31, which may be provided with a through hole. During assembly, a fastener such as a screw may be passed through the through hole of the ear portion 31 and threadedly assembled with the cylindrical portion 23.

[0093] This facilitates the installation and fixation of the first sensing member 3 and the mounting member 2 , ensures the stability of the fixed structure, and prevents the mounting member 2 from becoming loose and displaced when subjected to floating impact from the second sensing member 4 .

[0094] In some embodiments, a slot 27 is provided on the bottom side of the mounting member 2 for inserting the float 1, the recess 26 is provided at the bottom of the slot 27, the second sensing member 4 is provided at the top of the float 1, and at least part of the second sensing member 4 protrudes from the surface of the float 1 and forms a convex portion 41.

[0095] For example, Figure 2 As shown, a portion of the bottom of the mounting member 2 may protrude downward to form a protrusion, and a slot 27 may be disposed within the protrusion. Slot 27 is vertically aligned with the first sensing member 3. The slot opening of slot 27 may be arranged facing in the same direction, and the recess 26 may be disposed on the bottom wall of slot 27. The second sensing member 4 may be overmolded onto the top of the floating body 1, with a portion of the second sensing member 4 located outside the floating body 1 and forming the protrusion 41.

[0096] During use, the top portion of the float 1 can always be inserted and fitted into the slot 27 , thereby ensuring the guidance of the float 1 in floating up and down, and further preventing the second sensing element 4 from being skewed or deviated when approaching the first sensing element 3 .

[0097] In some embodiments, the recess 26 is a spherical cap groove, and the protrusion 41 is spherical cap-shaped. This allows the radial dimension of the recess 26 to gradually decrease from bottom to top, thereby enhancing the guidance and alignment accuracy of the contact between the protrusion 41 and the recess 26. Furthermore, the protrusion 41 and the recess 26 can be in curved contact, achieving a stop effect in both the vertical and horizontal directions, further enhancing the positioning and restraining effect.

[0098] In some embodiments, the first sensing element 3 is a Hall effect sensor, and the second sensing element 4 is a magnet. The magnet can be spherical and embedded in the top of the float 1. Because magnets can exert their own magnetic field, placing the second sensing element 4 on the float 1 eliminates the effects of moisture and other factors on the first sensing element 3, further ensuring waterproofness and operational stability.

[0099] The humidifier according to the embodiment of the present invention is described below.

[0100] The humidifier in the embodiment of the present invention includes a liquid level monitoring component, which may be the liquid level monitoring component described in any of the above embodiments.

[0101] In some embodiments, as Figure 3As shown, the humidifier includes a main body assembly 6 and a water tank assembly 7.

[0102] like Figure 4 As shown, the main assembly 6 includes a main housing 61 and an air inlet mesh. The air inlet mesh is disposed within the main housing 61 and forms the mounting member 2. Specifically, the air inlet mesh can be generally disc-shaped and can be fixed to the middle of the main housing 61. The main assembly 6 can also include blades 62, etc. The blades 62 can be mounted on the top side of the air inlet mesh and can be coaxially arranged with the air inlet mesh.

[0103] like Figure 5 and Figure 6 As shown, the water tank assembly 7 includes a water tank 71 and a bracket 72. The water tank 71 can be a box-shaped structure. The water tank 71 is connected to the bottom of the main shell 61 and is used to store liquid. The main shell 61 and the water tank 71 can be assembled into a humidifier shell.

[0104] Bracket 72 is fixed within water tank 71, and float 1 passes through bracket 72 and can float up and down relative to bracket 72. For example, bracket 72 can have a frustum structure, with a hollow interior. Bracket 72 can be mounted to the bottom wall of water tank 71 by means of snap-fitting, fasteners, etc. The top of bracket 72 can have a concave portion, allowing float 1 to flexibly fit within bracket 72, with a portion of float 1 extending from the concave portion of the top of bracket 72. The second sensing element 4 is disposed on the portion of float 1 extending from bracket 72.

[0105] During use, the float 1 will float up and down with the change of the liquid level, thereby adjusting the distance between the second sensing element 4 and the first sensing element 3. Due to the limiting effect of the bracket 72, the float 1 can be prevented from falling out of the bracket 72, ensuring the structural stability of the assembly of the float 1 and the bracket 72.

[0106] In some embodiments, the water tank assembly 7 further includes a filter element 73, which is disposed in the water tank 71 and can be sleeved on the outer peripheral side of the bracket 72.
