[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the water tank assembly applied to the humidifier during use or operation, other than those depicted in the figure. For example, if the water tank assembly applied to the humidifier in the figure undergoes a positional flip, orientation change, or movement change, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The water tank assembly applied to the humidifier may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0038] To address the technical problem that existing water pump components cannot be disassembled, making it difficult for users to effectively clean or replace them, this application provides a water tank assembly for humidifiers.

[0039] Figures 1 to 7 A water tank assembly for a humidifier provided in this application includes a water tank 1 and a water pump assembly 2 detachably connected to the water tank. The water pump assembly 2 includes a pump body 201 and a bracket 202 for fixing the pump body 201.

[0040] The bracket 202 is provided with a snap-fit ​​opening 2023, and the snap-fit ​​opening 2023 has a first abutting surface 2023a;

[0041] The side wall of the water tank 1 is provided with a locking protrusion 101, and the locking protrusion 101 has a second abutment surface 1011;

[0042] The engaging protrusion 101 can be inserted into the engaging opening 2023 in the first direction, so that the first abutting surface 2023a and the second abutting surface 1011 abut against each other in the second direction.

[0043] The first direction and the second direction are perpendicular to each other.

[0044] In the above technical solution, the water tank assembly provided in this application achieves a detachable connection between the water tank 1 and the water pump assembly 2 through a specific snap-fit ​​structure. Specifically, the side wall of the water tank 1 is provided with a snap-fit ​​protrusion 101, and the bracket 202 is provided with a snap-fit ​​opening 2023. The snap-fit ​​opening 2023 has a first abutment surface 2023a, and the snap-fit ​​protrusion 101 has a second abutment surface 1011. During installation, the user inserts the snap-fit ​​protrusion 101 into the snap-fit ​​opening 2023a on the bracket 202 along a first direction (e.g., the horizontal direction). When the snap-fit ​​protrusion 101 is inserted into the appropriate position, the bracket 202 is moved vertically, so that the first abutment surface 2023a and the second abutment surface 1011 abut against each other in a second direction perpendicular to it (e.g., the vertical direction), thereby firmly fixing the water pump assembly 2 to the water tank 1. During disassembly, only an appropriate reverse force needs to be applied to pull the snap-fit ​​protrusion 101 out of the snap-fit ​​opening 2023 along the first direction.

[0045] This snap-fit ​​structure requires no special tools. Users can easily install and remove the water pump assembly 2 by simply inserting and pulling it out manually, greatly reducing the difficulty of operation. Even ordinary users can easily complete the task.

[0046] Compared to traditional screw fixing methods, this snap-fit ​​structure eliminates the steps of tightening and loosening screws, significantly shortening the time required for installation and disassembly, and improving user efficiency. Its advantages are even more obvious in scenarios where the water tank 1 needs to be cleaned frequently or the water pump assembly 2 needs to be replaced.

[0047] In one possible implementation, a spring piece 2024 is provided near the first abutting surface 2023a of the snap-fit ​​opening 2023, and a positioning protrusion 2024a is provided on the spring piece 2024.

[0048] A notch 1012 is provided on the engagement protrusion 101;

[0049] When the first abutting surface 2023a abuts against the second abutting surface 1011, the positioning protrusion 2024a extends into the notch 1012 to form a positioning fit. A spring piece 2024 is provided near the first abutting surface 2023a at the snap-fit ​​opening 2023. The spring piece 2024 has a positioning protrusion 2024a, and a notch 1012 is provided at a corresponding position on the snap-fit ​​protrusion 101. When the snap-fit ​​protrusion 101 is inserted into the snap-fit ​​opening 2023 in the first direction, and the first abutting surface 2023a and the second abutting surface 1011 abut against each other to complete the initial connection, the spring piece 2024 undergoes elastic deformation due to the compression of the snap-fit ​​protrusion 101. As the engaging protrusion 101 continues to be inserted into place, the positioning protrusion 2024a on the spring piece 2024 will accurately extend into the notch 1012 on the engaging protrusion 101. At this time, the spring piece 2024 recovers some of its elastic deformation, so that the positioning protrusion 2024a and the notch 1012 fit tightly together, thereby forming a positioning fit.

[0050] The engagement of the positioning protrusion 2024a and the notch 1012 further restricts the degree of freedom of movement of the engaging protrusion 101 within the engaging opening 2023, effectively preventing the water pump assembly 2 from loosening or shifting due to vibration, shaking or slight external force during use, ensuring that the connection between the water pump assembly 2 and the water tank 1 remains stable and reliable, and guaranteeing the normal operation of the humidifier.

[0051] In the complex environment in which the humidifier (not shown in the attached figure) operates, such as when subjected to interference factors such as external collisions or vibrations of the equipment itself, this positioning fit can provide additional restraint, reduce the relative movement between connected parts, and reduce the risk of failure due to loose connections.

[0052] Please refer to Figure 1 In one possible implementation, the bottom of the water tank 1 is provided with a groove 102, and one end of the bracket 202 is placed in the groove 102. The groove 102 at the bottom of the water tank 1 allows one end of the bracket 202 to be inserted into the water pump assembly 2 during installation. The shape and size of the groove 102 are adapted to the end of the bracket 202, allowing the bracket 202 to be embedded therein. The sidewalls and bottom of the groove 102 provide support and limit the position of the bracket 202, thereby achieving initial positioning and fixation of the water pump assembly 2 on the water tank 1.

[0053] Understandably, the groove 102 provides clear installation position and direction guidance for the bracket 202, allowing users to quickly and accurately place one end of the bracket 202 into the groove 102, avoiding installation deviations caused by lack of positioning, ensuring that the water pump assembly 2 can be correctly installed on the water tank according to design requirements, and improving the accuracy and consistency of installation.

[0054] Please refer to Figure 2In one possible implementation, the bracket 202 has a mounting groove 2025 at one end near the groove 102, and the pump body 201 is detachably mounted in the mounting groove 2025. The mounting groove 2025 is specifically provided at one end of the bracket 202 near the bottom of the groove 102 of the water tank 1. The shape, size, and structure of the mounting groove 2025 are adapted to the pump body 201. When installing the pump body 201, it is placed into the mounting groove 2025, and the pump body 201 is positioned and supported by the side walls, bottom, and other structures of the mounting groove 2025. Simultaneously, a detachable connection method (such as a snap-fit ​​or bolt connection) is used to fix the pump body 201 in the mounting groove 2025, ensuring the stability of the pump body 201 during normal operation. When it is necessary to disassemble the pump body 201, the corresponding connection structure is released, and the pump body 201 can be removed from the mounting groove 2025.

[0055] The mounting slot 2025 provides a clear installation position for the pump body 201. Users do not need to perform complicated positioning and adjustment operations when installing the pump body 201. They only need to put the pump body 201 into the mounting slot 2025 and fix it, which greatly shortens the installation time and improves the installation efficiency.

[0056] When the pump body 201 malfunctions or requires maintenance, its detachable design allows users to easily remove it from the mounting slot 2025 for repair, replacement, or cleaning. After maintenance, the pump body 201 can be quickly reinstalled back into the mounting slot 2025, reducing maintenance difficulty and cost.

[0057] Please refer to this again. Figure 1 In one possible implementation, at least one limiting protrusion 103 is provided at the bottom of the water tank 1 near the groove 102. The limiting protrusion 103 abuts against the end of the bracket 202 to limit the radial displacement of the bracket 202. When the bracket 202, on which the pump body 201 is mounted, is placed into the groove 102 at the bottom of the water tank 1, the end of the bracket 202 abuts against the limiting protrusion 103. The limiting protrusion 103 acts like a "positioning post," preventing the bracket 202 from moving in the radial direction (i.e., the direction perpendicular to the axial direction of the bracket 202). Even if the water tank 1 is subjected to external impacts or vibrations, or if the water pump assembly 2 generates a certain force during operation, the limiting protrusion 103 will always remain in contact with the end of the bracket 202, preventing the bracket 202 from radially shifting.

[0058] Please refer to this again. Figure 1In one possible implementation, the end of the bracket 202 furthest from the mounting slot 2025 is provided with an electrical connection terminal 2026 for electrical connection with an external power source. When the water tank assembly is installed on the humidifier body (not shown in the drawings), the electrical connection terminal 2026 on the bracket 202 corresponds to the power line or power interface inside the humidifier. Electrical connection with an external power source is achieved by inserting the electrical connection terminal into the power interface, contacting the power contacts, or otherwise using other suitable methods. At this time, electrical energy from the external power source can be transmitted to the pump body 201 through the electrical connection terminal 2026, providing the pump body 201 with the power required for operation.

[0059] Electrical energy is transmitted from an external power source to the pump body 201 via the electrical connection terminal 2026, energizing the motor and other electrical components inside the pump body 201, which then begin to operate. The motor drives the pump body 201 to operate, drawing water from the water tank 1 and delivering it to the atomizing component of the humidifier to achieve the humidification function.

[0060] It should be noted that, in one possible implementation, the pump body 201 is provided with a water supply pipe (not shown in the attached drawings), and the bracket 202 is provided with a water pipe connector 2027. The water supply pipe extends vertically upward and is connected to the water pipe connector 2027. As the core component of the humidifier that realizes the water pumping function, the pump body 201's internal structure can generate suction to draw water from the water tank 1. The water supply pipe is connected to the pump body 201. When the pump body 201 is working, water is drawn from the water tank 1 into the pump body 201 and then enters the water supply pipe.

[0061] The water supply pipe extends vertically upwards from the pump body 201. This vertical upward design helps water flow smoothly under the combined action of gravity and the pressure of the pump body 201, reducing water flow resistance. The water pipe connector 2027 on the support 202 is a structure specifically designed for connecting the water supply pipe, and its interface size and shape match the water supply pipe. The end of the water supply pipe is inserted into or connected to the water pipe connector 2027 to connect the two.

[0062] Once the water supply pipe is connected to the water pipe connector 2027, a complete water channel is formed. The pump body 201 continues to work, transporting the water in the water tank 1 through the water supply pipe to the water pipe connector 2027, and then transporting the water to other components of the humidifier (such as the spray element), providing a water source for the humidifier's humidification function.

[0063] Additionally, a sealing ring (not shown in the attached diagram) is sandwiched between the water pipe connector 2027 and the water supply pipe. The sealing ring is made of a material with good elasticity and sealing performance, such as rubber or silicone. Before connecting the water supply pipe to the water pipe connector 2027, the sealing ring is placed at the connection point between the water pipe connector 2027 and the water supply pipe. The size and shape of the sealing ring are designed according to the interface specifications of the water pipe connector 2027 and the water supply pipe to ensure a tight fit between them.

[0064] When the water pipe is inserted into or connected to the water pipe connector 2027, the water pipe connector 2027 and the water pipe apply pressure to the intermediate sealing ring. Because the sealing ring is elastic, it deforms under pressure, filling the gap between the water pipe connector 2027 and the water pipe, forming a tight sealing barrier.

[0065] During humidifier operation, pump body 201 transports water from water tank 1 through water pipe to water pipe connector 2027, and then to other components of the humidifier. The presence of the sealing ring effectively prevents water from leaking out from the connection between water pipe connector 2027 and water pipe, ensuring the normal operation of the water system.

[0066] In one possible implementation, the bracket 202 includes a first bracket 2021 and a second bracket 2022, which are detachably connected. When the first bracket 2021 and the second bracket 2022 need to be assembled into a complete bracket, the connection points of the two are engaged through specific operation methods (such as thread tightening, snap-fit ​​engagement, bolt fixing, etc.). For example, if a snap-fit ​​connection is used, the snaps on the first bracket 2021 are aligned with the slots on the second bracket 2022, and a certain pressure is applied to make the snaps engage in the slots, thus achieving the connection between the two; if a bolt connection is used, bolts are passed through the corresponding holes on the first bracket 2021 and the second bracket 2022, and the nuts are tightened to complete the connection.

[0067] When it is necessary to disassemble bracket 202, proceed in the reverse order of the connection process. For snap-fit ​​connections, apply appropriate external force to disengage the snaps from the slots; for bolted connections, loosen the nuts and remove the bolts to separate the first bracket 2021 and the second bracket 2022.

[0068] During the use of the humidifier, if a part of the bracket 202 (such as the first bracket 2021 or the second bracket 2022) is damaged or malfunctions, since the first bracket 2021 and the second bracket 2022 are detachably connected, the user can replace only the damaged part without replacing the entire bracket 202, reducing maintenance costs and material waste. At the same time, this design also facilitates the maintenance and inspection of internal parts of the bracket 202 (such as components related to the water pump).
