Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to a humidifier with high humidification efficiency and easy to use. Background Technology

[0002] Humidifiers, as household appliances that improve ambient humidity, are widely used in dry seasons or air-conditioned rooms. A typical humidifier usually consists of an upper casing housing a fan and control circuitry, and a water tank for storing water and housing the filter. For safe use, humidifiers generally include a water shortage detection device; one common design integrates a float-type water shortage detection module at the center of the filter assembly.

[0003] However, this existing design has many drawbacks: First, the detection module located in the center of the filter element occupies valuable ventilation cross-section, increasing airflow resistance and resulting in insufficient air intake, making it difficult to improve humidification efficiency; second, due to manufacturing limitations, the floats vary in weight and buoyancy between individuals, leading to inconsistent residual water levels in the water tank when a water shortage alarm is triggered, affecting product reliability and user experience; third, the filter element needs to be cleaned regularly, but most products are inconvenient to disassemble, affecting maintainability; in addition, the fan assembly is usually fixed with screws, making it difficult to guarantee assembly accuracy and dynamic balance, which can easily lead to excessive operating noise; finally, damp filter elements and water tanks are prone to bacterial growth, potentially causing secondary pollution.

[0004] Therefore, there is an urgent need in this field for a new type of humidifier that can fundamentally solve the above problems from a structural perspective, and achieve a comprehensive performance improvement in terms of high efficiency, low noise, high reliability, easy maintenance, and greater hygiene.

Its core objective is to solve the problems of high wind resistance and low efficiency caused by the unreasonable layout of the water shortage detection module through structural innovation, while simultaneously improving detection accuracy, reducing operating noise, facilitating user maintenance, and enhancing product hygiene.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a humidifier with high humidification efficiency and ease of use, comprising:

[0008] The upper housing assembly includes the upper housing, the fan assembly, and the water shortage detection assembly;

[0009] The water tank assembly includes a water tank, a filter element assembly disposed within the water tank, and a water shortage detection module independently disposed on one side of the water tank;

[0010] The fan assembly is installed inside the upper housing using a screwless fixing method;

[0011] The lower end of the motor bracket of the fan assembly is provided with an air inlet, which fits with the air outlet of the filter element assembly to form an air inlet channel. The upper edge of the motor bracket cooperates with the air guide edge inside the upper shell to form an air outlet channel.

[0012] The water shortage detection module works in conjunction with the water shortage detection component of the upper shell assembly to detect the water level in the water tank.

[0013] As a preferred technical solution of this utility model, the water shortage detection module includes a bracket and two stainless steel shafts. The stainless steel shafts are fixed by the bracket, with one end extending into the water in the water tank and the other end connected to the elastic probe of the water shortage detection component to form a signal detection loop.

[0014] As a preferred embodiment of the present invention, the filter element assembly includes a filter element rotating cover, a filter element, and a filter element support. The filter element rotating cover is detachably connected to the filter element support via a snap-fit ​​structure.

[0015] As a preferred embodiment of this utility model, the snap-fit ​​structure includes a female snap-fit ​​on the filter element rotating cover and a male snap-fit ​​on the filter element support, thereby achieving detachable fixing of the filter element through rotational engagement.

[0016] As a preferred technical solution of this utility model, the fan assembly further includes a motor, a motor shaft and a fan blade, wherein the fan blade and the motor shaft are integrally formed by in-mold injection molding, and the motor shaft is connected to the motor drive.

[0017] The fan assembly also includes a copper sleeve, a rubber elastic ring, and a snap ring positioning plate;

[0018] The motor and the copper sleeve are fixed to the middle positioning column of the motor bracket by positioning and riveting with a jig;

[0019] The motor shaft passes through a rubber elastic ring, a copper sleeve, and another rubber elastic ring in sequence, and the positioning groove at the end of the motor shaft is clamped and fixed by a snap ring positioning piece.

[0020] As a preferred embodiment of this utility model, it further includes a UV disinfection module, which is disposed in the middle of the motor bracket of the fan assembly and faces the filter element assembly; the UV disinfection module includes a UV lamp plate, a quartz glass lens, and a silicone sealing ring, the quartz glass lens is sealed by the silicone sealing ring and fixed to the motor bracket by screws.

[0022] This utility model has the following beneficial effects:

[0023] Significantly improved humidification efficiency: By moving the water shortage detection module from the center of the filter to the side of the water tank, the core ventilation area of ​​the filter assembly is completely freed up, effectively reducing air resistance. Combined with an optimized short-path direct ventilation duct design, airflow loss inside the unit is greatly reduced, thus achieving a dual improvement in humidification efficiency and airflow volume.

[0024] Accurate and reliable water shortage detection: The conductive detection scheme, which uses a fixed stainless steel shaft and a flexible probe, replaces the traditional floating mechanical structure, completely eliminating detection errors caused by the weight deviation of parts. This ensures a high degree of consistency in water level for each water shortage alarm and improves product reliability.

[0025] Smooth operation and lower noise: The fan components are made of in-mold injection molding to ensure initial dynamic balance, and combined with the screwless assembly process of fixture positioning and riveting and snap ring fixing, the concentricity and stability of the fan operation are ensured, reducing the operating noise caused by vibration from the source.

[0026] User-friendly and worry-free maintenance: The filter element assembly adopts a screw-on detachable structure, allowing users to easily disassemble and clean the filter element without tools, greatly improving the product's ease of use and maintenance convenience, and helping to extend the filter element's service life.

[0027] Strong hygiene and health protection: By adding a UV disinfection module facing the filter and water tank, and by treating the water tank material with antibacterial agents, bacteria can be effectively killed and inhibited, ensuring that the output water vapor is clean and hygienic, and protecting the health of users.

Detailed Implementation

[0042] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0044] Please see Figures 1 to 3 The humidifier provided by this utility model has high humidification efficiency and is easy to use. It is composed of two main parts: the upper shell assembly 10 and the water tank assembly 11.

[0045] Regarding the upper housing assembly 10: The upper housing assembly 10 includes an upper housing 101, a fan assembly 103, a water shortage detection assembly 104, and a guide ring 106. The upper housing 101 has an air outlet mesh at its top and a specific air guide edge 1011 formed inside. The fan assembly 103 is installed inside the upper housing 101 using a screwless fixing method detailed below. The water shortage detection assembly 104 is fixed to one side of the motor bracket 1031 of the fan assembly 103, and has two elastically retractable probes 1041 mounted on it. The guide ring 106 is fixed inside the upper housing 101, and its edge is designed with a guide slope and groove positioning features 1061.

[0046] Regarding the water tank assembly 11: The water tank assembly 11 includes a water tank 111, a filter element assembly 112, and a water shortage detection module 113. A transparent water level gauge 114 is provided on the side of the water tank 111 for easy observation of the water level. The filter element assembly 112 is housed in the central cavity of the water tank 111. The water shortage detection module 113 is independently and fixedly installed on one side of the water tank 111 via a bracket, completely spatially separated from the filter element assembly 112.

[0047] Regarding the implementation method of the water shortage detection function:

[0048] Combination Figure 4 and Figure 5The water shortage detection module 113 consists of a bracket 1131 and two parallel and equal-length stainless steel shafts 1132. The stainless steel shafts 1132 are inserted into the positioning holes on the upper part of the bracket 1131 until they are abutted by the internal limiting structure, thus being firmly fixed. When the upper shell assembly 10 is assembled with the water tank assembly 11, the inclined surface and groove feature 1061 of the guide ring 106 guide the water tank assembly 11 into accurate position. At this time, the two elastic probes 1041 on the water shortage detection assembly 104 extend downwards under the action of spring force and form stable electrical contact with the top ends of the two stainless steel shafts 1132 of the water shortage detection module 113, thereby forming a complete electrical signal detection circuit.

[0049] The detection logic is as follows: When the water level in the tank exceeds the bottom of the stainless steel shaft 1132, the water acts as a conductive medium, creating electrical continuity between the two stainless steel shafts. This closes the detection circuit, and the control system determines that the water level is normal. When the water level drops below the bottom of the stainless steel shaft 1132, the conductive path is cut off, the detection circuit is broken, and the control system immediately triggers a water shortage alarm signal. Because the position of the stainless steel shaft 1132 is absolutely fixed, the water level height that triggers the alarm remains constant each time, ensuring the consistency and accuracy of the detection.

[0050] Regarding the implementation method of detachable filter cartridge assembly:

[0051] See Figure 10 The filter element assembly 112 consists of a filter element rotating cover 1121, a filter element 1122, and a filter element support 1123. The filter element 1122 can be inserted along the guide structure on the filter element support 1123. A rotating female buckle 1124 is provided on the inner wall of the filter element rotating cover 1121, while a rotating male buckle 1125 is provided on the corresponding position on the outer side of the filter element support 1123. The user can reliably press and fix the filter element 1122 by rotating the filter element rotating cover 1121 to engage the rotating female buckle 1124 and the rotating male buckle 1125. Reverse rotation easily opens the cover, allowing the filter element 1122 to be removed for cleaning or replacement. This ingenious buckle design enables quick assembly and disassembly without tools.

[0052] Implementation methods for screwless fixing of fan components and optimization of air ducts:

[0053] See Figure 6 , Figure 7 and Figure 8 The screwless fixing method of the fan assembly 103 is the key to achieving low-noise operation.

[0054] First, the fan blade 1032 and the motor shaft 1034 are manufactured as a whole by in-mold injection molding, which fundamentally ensures the extremely high coaxiality of the fan blade and the motor shaft, laying the foundation for good dynamic balance. A magnetic ring 1039 is fixed inside the fan blade 1032 by a fixture and positioning riveting.

[0055] Secondly, the motor 1037 and the copper sleeve 1038 are positioned using a special fixture and fixed to the positioning column in the center of the motor bracket 1031 using a riveting process.

[0056] Then, the motor shaft 1034 passes through a rubber elastic ring 1036, a copper sleeve 1038, and another rubber elastic ring 1036 in sequence.

[0057] Finally, a retaining ring locating piece 1035 is used to clamp and fix the motor shaft 1034 in the locating slot at the end, completing the entire assembly. During this process, the rubber elastic ring 1036 effectively absorbs axial clearance, restricts the vertical movement of the fan blade 1032 during operation, and further stabilizes the operating state.

[0058] This complete screwless fixing solution not only improves assembly efficiency and consistency, but more importantly, it ensures the smooth and quiet operation of the fan at high speed through precise positioning and elastic buffering.

[0059] Regarding air duct optimization: Please refer to the following: Figure 2 The lower end of the motor bracket 1031 has an air inlet, which is closely fitted with the air outlet at the upper end of the filter element assembly 112 (i.e., the central opening of the filter element rotating cover 1121), forming an extremely short and direct air intake channel. After the humidified air flows out through the filter element, it is drawn in by the fan almost without obstruction. Then, driven by the fan blades 1032, the air is concentrated and discharged from the annular air outlet channel formed between the upper edge of the motor bracket 1031 and the air guide edge 1011 inside the upper shell 101. This "straight in and straight out" airflow layout minimizes airflow resistance and path loss, and is one of the core structural innovations for improving humidification efficiency.

[0060] Regarding the implementation method of the UV disinfection module:

[0061] See Figure 7 and Figure 9To further ensure hygiene, a UV disinfection module 107 is integrated in the middle of the motor bracket 1031 of the fan assembly 103. The assembly sequence is as follows: first, the UV lamp plate 1071 is initially fixed to the motor bracket 1031 with screws 1072; then, the silicone sealing ring 1073 and the quartz glass lens 1074 are placed sequentially into the dedicated slot of the UV bracket 1075; finally, the UV bracket 1075 is firmly secured to the motor bracket 1031 with screws 1072. The short-wave ultraviolet rays emitted by the UV lamps can penetrate the highly transparent quartz glass lens 1074 and vertically irradiate the surface of the filter assembly 112 below and the water in the water tank 111, effectively killing bacteria and viruses. The silicone sealing ring 1073 plays a crucial sealing role, preventing internal moisture from rising and corroding the UV lamp plate 1071, ensuring its long-term stable operation.

[0062] Implementation methods for the guide and positioning structure:

[0063] See again Figure 2 and Figure 3 The upper shell assembly 10 is assembled with the water tank assembly 11 via its internal guide ring 106. The unique guide slope on the guide ring 106 ensures a high initial docking tolerance and smooth guidance; while the groove positioning feature 1061 provides precise positioning and locking when it engages with the corresponding protrusion on the water tank assembly 11. This design ensures that the upper shell assembly 10 and the water tank assembly 11 are quickly and accurately assembled each time, especially guaranteeing that the probes of the water shortage detection module 113 and the water shortage detection component 104 can be precisely aligned and reliably contacted, preventing detection function failure due to misalignment, and improving user experience and product quality.
