Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and more specifically, to a water tank and humidifier with an easy-to-disassemble float. Background Technology

[0002] The water tank is the water storage component of a humidifier. It usually contains a float, which controls the opening and closing of the valve by rising and falling with the water level, thereby achieving automatic water replenishment or shut-off.

[0003] Currently, most humidifier floats are installed inside the water tank via float levers. Specifically, the bottom of the water tank has limiting holes, and both ends of the float lever are inserted into the corresponding limiting holes, and are fixed in place by an interference fit. This fixing method has the following main drawbacks:

[0004] Because the water tank stores water for extended periods, the float needs to be removed and cleaned periodically after prolonged use. However, during disassembly, users need to apply considerable force to pull the float lever out of the limiting hole, making cleaning inconvenient. Furthermore, repeated disassembly and reassembly can easily damage the structure of the float lever or the limiting hole in the base, causing the two to loosen and affecting the float's water level control function.

[0005] Therefore, how to conveniently and non-destructively install and remove the float lever from the bottom of the water tank is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a water tank that facilitates the disassembly and assembly of the float. The water tank is provided with a second support at the bottom that can move relative to the first support, which realizes the convenient and non-destructive disassembly and assembly of the float lever, thereby improving the service life and reliability of the humidifier water tank, while also facilitating the cleaning and maintenance of the water tank.

[0007] Another objective of this invention is to provide a humidifier that includes a water tank with a float that is easy to assemble and disassemble.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A water tank with an easy-to-install float, comprising:

[0010] The float lever has a first protrusion and a second protrusion on the same axis;

[0011] The water tank body has a first support and a second support spaced apart at its bottom. The second support is movable relative to the first support between a locked position and a disassembled position. The first support has a first limiting hole that rotatably engages with the first protrusion. The second support has a second limiting hole that rotatably engages with the second protrusion.

[0012] When the second support is in the locked position, the first protrusion is accommodated in the first limiting hole, the second protrusion is accommodated in the second limiting hole, and the float lever is rotatably clamped between the first support and the second support.

[0013] When the second support moves to the disassembly / assembly position, the center distance between the first limiting hole and the second limiting hole is greater than the center distance between the first protrusion and the second protrusion.

[0014] Preferably, the bottom of the water tank body is provided with a boss, and the boss is located on the first side of the second support away from the first support;

[0015] The water tank also includes an elastic element connected between the boss and the first side of the second support. When the second support is in the locked position, the elastic element is in a natural or pre-compressed state. When the second support moves to the disassembly position, the elastic element is in a compressed state.

[0016] Preferably, the first side of the second support and / or the boss is provided with a limiting protrusion, which radially abuts against the end of the elastic member to achieve radial limiting.

[0017] Preferably, the bottom of the water tank body is provided with a boss, and the boss is located on the first side of the second support away from the first support;

[0018] The boss is provided with a guide portion, the length direction of which is parallel to the axial direction of the second protrusion and the second limiting hole. The first side of the second support is provided with a guide portion, which is slidably engaged with the guide portion.

[0019] Preferably, the guide portion includes a first plate and is disposed on the side of the boss facing the second support, and the guide portion includes a second plate, which is slidably abutted against the end face of the first plate away from the boss.

[0020] Preferably, a base plate is provided between the second support and the bottom of the water tank body, and a third limiting hole is provided on the base plate. The length direction of the third limiting hole is parallel to the axial direction of the second protrusion and the second limiting hole. A limiting member is provided at the bottom end of the second support, and the limiting member is slidably disposed in the third limiting hole.

[0021] Preferably, the end of the limiting member opposite to the second support extends beyond the third limiting hole and is provided with a radially protruding anti-detachment part, the size of which is larger than the width of the third limiting hole.

[0022] Preferably, when the limiting member slides to abut against the first end of the third limiting hole along its length, the second support is in the locked position; when the limiting member slides to abut against the second end of the third limiting hole along its length, the second support is in the disassembly / assembly position.

[0023] Preferably, a movable space is left between the first side of the second support away from the first support and the side wall adjacent to the water tank body, for the second support to move.

[0024] Preferably, the first support is movable relative to the second support between a locking position and a disassembly position, and the first support and the second support move in opposite directions.

[0025] A humidifier comprising a water tank with a removable float as described in any of the preceding claims.

[0026] Preferably, the water tank is detachably disposed inside the main unit, and the water container is detachably disposed on the main unit and connected to the water tank for supplying water to the water tank.

[0027] This utility model provides a water tank that facilitates the assembly and disassembly of floats. It transforms the traditional interference fit insertion and removal of the float lever into a simple displacement operation. Specifically, during disassembly, simply move the second support to the disassembly / removal position. At this point, the center distance between the first and second limiting holes is greater than the center distance between the first and second protrusions, causing the second protrusion to disengage from the second limiting hole and providing space for the first protrusion to be removed from the first limiting hole. This releases the clamping limit on the float lever, allowing the operator to easily remove it. During assembly, first insert the first protrusion on the float lever into the first limiting hole of the first support, then move the second support to the locking position, allowing the two protrusions to be accommodated in the two limiting holes respectively, thus achieving rotatable clamping of the float lever.

[0028] As can be seen from the above description, this application has the following beneficial effects:

[0029] 1. No tools or force are required for disassembly and assembly. The float lever can be disassembled and assembled simply by moving the second support to the disassembly and assembly position, removing or installing the float lever, and resetting the second support to the locking position. This disassembly and assembly method is simple and convenient, allowing the float to be removed from the inside of the water tank. There are no dead corners inside the water tank, making it convenient for operators to clean and maintain the water tank.

[0030] 2. The movement of the second support between the locking and disassembly positions replaces the traditional interference fit insertion. During disassembly, the second support moves away to release the constraint on the float lever; during installation, the second support resets to lock the float lever. Furthermore, the protrusion of the float lever and the limiting hole maintain a clearance fit rotational relationship, avoiding problems such as scratches, wear, deformation, or damage to the limiting hole caused by forced disassembly, thus achieving non-destructive disassembly and assembly of the float lever.

[0031] 3. Due to the non-destructive assembly and disassembly of the float lever, the float lever can always be firmly clamped by the first and second supports in the locked position to provide a reliable rotation fulcrum, ensuring that the float can rotate flexibly with the rise and fall of the water level, thereby improving the service life and reliability of the humidifier's water tank.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The core of this utility model is to provide a water tank that facilitates the disassembly and assembly of the float. The water tank has a second support at the bottom that can move relative to the first support, which realizes the convenient and non-destructive disassembly and assembly of the float lever, thereby improving the service life and reliability of the humidifier water tank, while also facilitating the cleaning and maintenance of the water tank.

[0041] Another core aspect of this invention is to provide a humidifier that includes a water tank with a float that is easy to assemble and disassemble.

[0042] Please refer to Figure 1 and Figure 2 This application provides a water tank with a float 1 that is easy to assemble and disassemble, including a float lever 11 and a water tank body 2.

[0043] The float lever 11 has a first protrusion 111 and a second protrusion 112 that are coaxial.

[0044] The bottom of the water tank body 2 is provided with a first support 21 and a second support 22 at intervals. The second support 22 is movable relative to the first support 21 between a locked position and a disassembled position. The first support 21 is provided with a first limiting hole 211 that rotatably engages with the first protrusion 111, and the second support 22 is provided with a second limiting hole 221 that rotatably engages with the second protrusion 112.

[0045] like Figure 2 As shown, when the second support 22 is in the locked position, the first protrusion 111 is accommodated in the first limiting hole 211, the second protrusion 112 is accommodated in the second limiting hole 221, and the float lever 11 is rotatably clamped between the first support 21 and the second support 22.

[0046] When the second support 22 moves to the disassembly position, the center distance between the first limiting hole 211 and the second limiting hole 221 is greater than the center distance between the first protrusion 111 and the second protrusion 112.

[0047] It should be added that float 1 is composed of float body 12 and float lever 11. Float lever 11 is typically rotatably mounted on the water tank body 2 to provide a fulcrum for the float body 12, allowing the float body 12 to float as the water level in the water tank body 2 rises and falls. Therefore, achieving convenient and non-destructive assembly and disassembly of float lever 11 also achieves convenient and non-destructive assembly and disassembly of the entire float 1.

[0048] In this embodiment, the end of the float lever 11 away from the float body 12 is provided with a protrusion 113. The protrusion 113 contacts or moves away from the water valve in the water tank. The position of the float lever 11 between the protrusion 113 and the float body 12 (as a rotation fulcrum) is provided with a coaxial first protrusion 111 and a second protrusion 112. The bottom of the water tank body 2 is provided with a first support 21 and a second support 22 at intervals. The first support 21 is provided with a first limiting hole 211, and the second support 22 is provided with a second limiting hole 221. The second support 22 can move relative to the first support 21 between a locked position and a disassembled position.

[0049] When the second support 22 is in the locked position, the first protrusion 111 and the second protrusion 112 are respectively housed in the first limiting hole 211 and the second limiting hole 221 to form a rotating pair. At the same time, the first support 21 and the second support 22 clamp the float lever 11 from both sides, constraining the five degrees of freedom of the float lever 11, while retaining the rotational degree of freedom about the axis of the first / second protrusion 112. This ensures that the float lever 11 provides a stable and reliable rotational fulcrum for the float body 12, and guarantees that the float 1 can float with the rise and fall of the water level. Additionally, the protrusion 113 and the float body 12 swing in opposite directions around the rotational fulcrum. As the water level drops, the protrusion 113 rises and contacts the water valve in the water tank, opening a channel to replenish the water tank. Conversely, as the water level rises, the channel in the water tank gradually closes, stopping the replenishment of water to the water tank.

[0050] When the second support 22 moves to the disassembly position, the center distance between the first limiting hole 211 and the second limiting hole 221 is greater than the center distance between the first protrusion 111 and the second protrusion 112. The second protrusion 112 can easily disengage from the second limiting hole 221 and provide space for the first protrusion 111 to be removed from the first limiting hole 211. This releases the clamping limit on the float lever 11, and the operator can easily remove the float lever 11.

[0051] Therefore, the water tank provided in this embodiment, which facilitates the disassembly and assembly of the float 1, has the following effects:

[0052] First, the float lever 11 can be disassembled and assembled simply by moving the second support 22 to the disassembly position, removing or installing the float lever 11, and resetting the second support 22 to the locking position. The disassembly and assembly operations are simple and convenient, which makes it easier for operators to clean and maintain the water tank.

[0053] Secondly, the protrusion of the float lever 11 and the limiting hole are in a clearance fit rotational relationship. After the second support 22 moves to the disassembly position, the clamping limit on the float lever 11 is released. The operator can easily remove the float lever 11 without overcoming the interference constraint, avoiding problems such as scratches, wear, deformation or damage to the limiting hole caused by forced disassembly and assembly, and realizing non-destructive disassembly and assembly of the float lever 11.

[0054] Third, due to the non-destructive disassembly and assembly of the float lever 11, the float lever 11 can always be firmly clamped by the first support 21 and the second support 22 in the locked position, so as to provide a reliable rotation fulcrum and ensure that the float 1 can rotate flexibly with the rise and fall of the water level, thereby improving the service life and reliability of the humidifier water tank.

[0055] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The bottom of the water tank body 2 is provided with a boss 23, which is located on the first side of the second support 22 away from the first support 21. The water tank also includes an elastic member 24, which is connected between the boss 23 and the first side of the second support 22. When the second support 22 is in the locked position, the elastic member 24 is in the natural state or pre-compressed state. When the second support 22 is moved to the disassembly position, the elastic member 24 is in the compressed state.

[0056] In this embodiment, a boss 23 is provided at the bottom of the water tank body 2. The boss 23 is located on the first side of the second support 22 away from the first support 21 and is a certain distance away from it. The two ends of the elastic member 24 are respectively connected between the boss 23 and the first side of the second support 22.

[0057] It should be added that the elastic element 24 being in its natural state refers to its original shape when it is not subjected to external force. The spring being in a pre-compressed state means that the elastic element 24 is already in a semi-compressed deformation state before installation, that is, it has generated pre-tension force when not loaded, and will exert a clamping force on the component after installation. The spring being in a compressed state means that the elastic element 24 is shortened and deformed under the action of external force, storing deformation energy.

[0058] When the second support 22 is in the locked position, the elastic element 24 is in either its natural or pre-compressed state. If the elastic element 24 is in the pre-compressed state, the second support 22 will be subjected to a clamping force when locked, which can eliminate the assembly gap between the second support 22 and the first support 21 of the float lever 11, thereby ensuring that the float lever 11 is firmly clamped and preventing the float lever 11 from shaking or making abnormal noise. If the elastic element 24 is in its natural state, it is suitable for situations where the assembly gap between the second support 22 and the first support 21 of the float lever 11 is extremely small or negligible. In this case, the second support 22 will not be subjected to a clamping force when locked, and the operator does not need to overcome the pre-tightening force to push the second support 22, making it easy to operate. Of course, the state of the elastic element 24 when the second support 22 is in the locked position can be adaptively selected according to specific processing requirements.

[0059] When the second support 22 is in the disassembly / assembly position, the elastic element 24 is in a compressed state, thus storing elastic potential energy. Therefore, when installing the float lever 11, the operator pushes the second support 22 away from the first support 21 (i.e., towards the disassembly / assembly position), compressing the elastic element 24 and storing its elastic potential energy. The float lever 11 is then inserted, specifically, the first protrusion 111 of the float lever 11 is placed into the first limiting hole 211 of the first support 21, and the second protrusion 112 of the float lever 11 is aligned with the second limiting hole 221 of the second support 22. When the operator releases the second support 22, the second support 22 automatically resets to the locking position using the elastic potential energy stored in the elastic element 24, thereby locking the float lever 11.

[0060] Therefore, the elastic element 24 added in this embodiment realizes the automatic reset of the second support 22, improving the convenience of operation.

[0061] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 and Figure 3 On the first side of the second support 22 away from the first support 21 (that is, the side facing the boss 23), and / or the boss 23 is provided with a limiting protrusion 222. The limiting protrusion 222 radially abuts against the end of the elastic member 24. That is, the radial inner wall of the limiting protrusion 222 contacts the radial outer wall of the end of the elastic member 24, thereby achieving radial limiting of the elastic member 24.

[0062] Thus, when the second support 22 moves to the disassembly position, the elastic element 24 restricts the movement of the end of the elastic element 24 in the radial plane, so that the elastic element 24 can only be compressed or extended along its axial direction, avoiding the elastic force direction of the elastic element 24 from deviating from the axis, so as to ensure that the second support 22 can be accurately reset to the locking position.

[0063] The limiting protrusion 222 is preferably a block structure that is approximately semi-circular. This mechanism has a semi-circular concave inner wall, which can better wrap around the end of the elastic member 24, restrict the radial movement of the elastic member 24, and prevent the elastic member 24 from falling off.

[0064] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The axial direction of the elastic element 24 is parallel to the axial direction of the rotational engagement between the second protrusion 112 and the second limiting hole 221.

[0065] The axial direction of the rotational engagement between the second protrusion 112 and the second limiting hole 221 is the moving direction of the second support 22. In this embodiment, the axial direction of the elastic element 24 is set parallel to the moving direction of the second support 22, and the direction of the elastic force of the elastic element 24 (i.e., the direction in which the elastic element 24 returns to its original shape) is consistent with the moving direction of the second support 22. On the one hand, the elastic force can be effectively transmitted to the second support 22 to efficiently drive the second support 22 to reset; on the other hand, the force on the second support 22 is balanced during movement, avoiding wobbling caused by the force direction deviating from the axis.

[0066] In one specific embodiment, the elastic element 24 is a compression spring. One end of the compression spring is fixed to the first side of the second support 22 and radially abuts against the limiting protrusion 222 thereon. The other end of the compression spring is fixed to the side of the boss 23 facing the first side of the second support 22.

[0067] Compression springs are mainly used to withstand axial pressure. They store deformation energy by generating compression deformation under axial force. By selecting a compression spring as the elastic element 24, the direction of the elastic force it generates under axial pressure is consistent with the direction of the reset movement of the second support 22. This allows for more effective transmission to the second support 22, resulting in less deformation energy loss and effectively ensuring the efficient reset of the second support 22.

[0068] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The boss 23 is provided with a guide part 231. The length direction of the guide part 231 is parallel to the axial direction of the second protrusion 112 and the second limiting hole 221. The first side of the second support 22 is provided with a guide part 223 that slides with the guide part 231.

[0069] It should be noted that the axial direction of the rotational engagement between the second protrusion 112 and the second limiting hole 221 is not only the direction of movement of the second support 22, but also the axial direction of both the second protrusion 112 and the second limiting hole 221. Furthermore, the first protrusion 111 and the second protrusion 112 of the float lever 11 are coaxial, and the first protrusion 111 is rotatably engaged with the first limiting hole 211 of the first support 21, and the second protrusion 112 is rotatably engaged with the second limiting hole 221 of the second support 22. It is therefore easy to conclude that the first limiting hole 211 and the second limiting hole 221 are also coaxial.

[0070] When the operator pushes the second support 22, the guide part 223 moves along the length direction of the guide part 231. Since the length direction of the guide part 231 is parallel to the axial direction of the second limiting hole 221, it can accurately guide the second limiting hole 221 of the second support 22 to align with the first limiting hole 211 of the first support 21. In this way, no matter where the second support 22 moves, the second limiting hole 221 of the second support 22 and the first limiting hole 211 on the first support 21 are always coaxial. When the second support 22 returns to the locked position, the two limiting holes can automatically align, ensuring that the two coaxial protrusions of the float lever 11 can be placed in the corresponding limiting holes, avoiding difficulties in installing the float lever 11 or wear due to misalignment of the two limiting holes.

[0071] It should also be noted that the guide part 223 and the guide part 231 slide together, which determines that the second support 22 moves only in the axial direction parallel to the rotational engagement between the second protrusion 112 and the second limiting hole 221. In other words, it determines that the second support 22 moves only in the axial direction parallel to the elastic member 24, which effectively avoids the bending deformation or wear of the elastic member 24 caused by the offset of the second support 22, and can play a role in protecting the elastic member 24.

[0072] In one specific embodiment, the guide portion 231 includes a first flat plate and is disposed on the side of the boss 23 facing the second support 22. The guide portion 223 includes a second flat plate, which slidably abuts against the end face of the first flat plate away from the boss 23. This structural arrangement of the guide portion 231 and the guide portion 223 has the advantages of simple structure, eliminating the need for complex guide grooves and reducing manufacturing costs. Furthermore, the second flat plate on the second support 22 slides closely against the first flat plate on the boss 23, resulting in a large contact area and providing stable support for the second support 22, thereby ensuring the smooth and stable movement of the second support 22.

[0073] Furthermore, a space is provided between the first plate and the bottom of the water tank body 2, and the elastic element 24 is located in the space. Moreover, the first plate is located above the elastic element 24, and a distance is left between the two to avoid interference between the first plate and the elastic element 24 when the second support 22 moves.

[0074] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 A base plate 25 is provided between the second support 22 and the bottom of the water tank body 2. A third limiting hole 251 is provided on the base plate 25. The length direction of the third limiting hole 251 is parallel to the axial direction of the second protrusion 112 and the second limiting hole 221. A limiting member is provided at the bottom end of the second support 22. The limiting member is slidably provided in the third limiting hole 251.

[0075] In this embodiment, a base plate 25 is provided between the second support 22 and the bottom of the water tank body 2. The base plate 25 has a third limiting hole 251. The third limiting hole 251 is an elongated hole, and its length direction is parallel to the axial direction of the rotational engagement between the second protrusion 112 and the second limiting hole 221 (that is, the moving direction of the second support 22).

[0076] The bottom end of the second support 22 is provided with a limiting member. The limiting member is located in the third limiting hole 251 and is clearance-fitted with it, so that the limiting member can slide in the length direction within the third limiting hole 251, but the limiting member cannot move in the depth direction perpendicular to the third limiting hole 251 (that is, the thickness direction of the base plate 25) to prevent the limiting member from sliding out of the third limiting hole 251.

[0077] When the operator pushes the second support 22, the limiting member slides within the third limiting hole 251. The third limiting hole 251 can guide and constrain the limiting member. Since the length direction of the third limiting hole 251 is parallel to the moving direction of the second support 22, it can accurately guide the second support 22 to move smoothly along the predetermined trajectory, avoiding deviation during the movement of the second support 22, thereby improving the stability and accuracy of the movement of the second support 22.

[0078] Furthermore, the length of the third limiting hole 251 is fixed. When the limiting member slides to abut against the first end of the third limiting hole 251 along its length, the second support 22 is in the locked position; when the limiting member slides to abut against the second end of the third limiting hole 251 along its length, the second support 22 is in the disassembly / removal position. Thus, by using both ends of the third limiting hole 251 to define the locking and disassembly / removal positions, the phenomenon of the float lever 11 being unable to be installed or removed due to the second support 22 not moving into position or moving excessively is avoided, ensuring precise switching of the second support 22 between the locking and disassembly / removal positions. On the other hand, there is no need to introduce other limiting structures (such as limiting blocks). The third limiting hole 251 and the limiting member guide the movement direction of the second support 22 while also limiting its travel distance, resulting in a simple structure and reduced manufacturing costs.

[0079] Based on the above embodiments, as a further preferred embodiment, the end of the limiting member facing away from the second support 22 extends beyond the third limiting hole 251 and is provided with a radially protruding anti-detachment part, the size of which is larger than the width of the third limiting hole 251. Thus, when the second support 22 is subjected to an upward pulling force, the anti-detachment part contacts the lower surface of the base plate 25, preventing the limiting member from disengaging from the third limiting hole 251. This ensures that the second support 22 and the base plate 25 are always connected through the slidingly fitted limiting member and limiting hole, thereby effectively improving the stability and accuracy of the movement of the second support 22.

[0080] In one specific embodiment, the limiting component is a screw, and the anti-loosening part is a nut. The screw can be installed in the mounting hole 224 at the bottom end of the second support 22 (e.g., Figure 3 As shown, the head of the screw passes through the third limiting hole 251 and extends out of the third limiting hole 251. The nut is located on the head of the screw and makes gap contact with the lower end face of the base plate 25, allowing the nut to move along the length direction of the third limiting hole 251 with the limiting member. This avoids the nut from contacting the base plate 25 too tightly and thus hindering the movement of the limiting member. At the same time, it can also vertically limit the limiting member and prevent the limiting member from detaching from the third limiting hole 251.

[0081] Based on the above embodiments, as a further preferred embodiment, a certain distance is maintained between the first side of the second support 22 away from the first support 21 and the side wall adjacent to the water tank body 2 to form a moving space. This moving space ensures that the second support 22 can move back and forth between the locked position and the disassembled position without obstruction.

[0082] Based on the above embodiments, as a further preferred embodiment, the first support 21 is movable relative to the second support 22 between another locking position and a disassembly position, and the moving directions of the first support 21 and the second support 22 are opposite.

[0083] It should be noted that the movement of the first support 21 can be achieved by a mechanism similar to that of the second support 22, for example, a sliding fit guide and guide part, elastic element and limiting element can be set separately for it.

[0084] Thus, the first support 21 and the second support 22 can move independently on their respective moving paths. The moving principle of the second support 22 is the same. When the first support 21 is in its corresponding locking position, the float lever 11 is clamped and locked by the first support 21 and the second support 22. When the first support 21 moves away from the second support 22 to its corresponding disassembly position, the center distance between the first limiting hole 211 and the second limiting hole 221 is greater than the center distance between the first protrusion 111 and the second protrusion 112, so as to release the clamping limit on the float lever 11 and facilitate the removal of the float lever 11.

[0085] Compared to moving the second support 22 alone to disassemble or assemble the float lever 11, moving the first support 21 and the second support 22 simultaneously can quickly increase or restore the center distance between the two limiting holes, thus making it easier to disassemble or assemble the float lever 11.

[0086] This utility model also provides a humidifier, including a water tank with a float 1 that is easy to assemble and disassemble as disclosed in the above embodiments.

[0087] Furthermore, the humidifier also includes a main unit and a water tank. The water tank is detachably located inside the main unit, and the water tank is detachably located on the main unit and connected to the water tank for supplying water to the water tank.

[0088] In this embodiment, the water tank can be used as an independent module, detachably installed inside the main unit for connection to the atomizer within the main unit. The water tank, used for water storage, is detachably mounted on the main unit, with its bottom outlet connecting to the water tank's inlet, thus supplying water from the tank to the water tank. During humidification operation, the water tank supplies water to the water tank, the float structure within the water tank controls the water level, and the atomizer draws water from the water tank for atomization. When the humidifier requires maintenance and cleaning, the entire water tank does not need to be removed; the water tank can be removed separately for cleaning. Then, the second support within the water tank can be moved, allowing for easy and non-destructive removal of the float structure. This facilitates thorough cleaning and maintenance of the water tank, improving the convenience of humidifier maintenance.

[0089] The structure of the water tank and other parts of the humidifier is not the focus of this application for improvement; please refer to existing technologies, and it will not be elaborated upon here.
