Description

Technical Field

[0001] This application relates to the field of humidifier technology, and more particularly to a humidifier with purification function. Background Technology

[0002] Currently, most humidifiers with purification functions adopt a structure of fixed humidifying cotton and independent water pumps. This solution not only leads to frequent malfunctions due to the risk of water pump blockage, but also significantly increases the overall height of the unit and reduces the space required for air ducts due to the stacked layout of the purification and humidification modules. In order to achieve dual functions, traditional equipment generally sacrifices humidification efficiency—the fixed humidifying cotton only absorbs water to the surface, and the utilization rate of the core area is less than 30%, while the water pump spraying structure further limits the increase in humidification capacity due to uneven water flow distribution. Utility Model Content

[0003] This application provides a humidifier with purification function to solve the technical problem of sacrificing humidification efficiency in order to achieve both purification and humidification functions in the prior art.

[0004] This application provides a humidifier with purification function, including:

[0005] A housing, wherein an air inlet and an air outlet are provided on the housing;

[0006] The purification unit is disposed inside the housing and located inside the air inlet;

[0007] The blower is housed inside the casing and located at the air outlet;

[0008] A humidification unit is disposed inside the housing and located between the purification unit and the blower.

[0009] A drive mechanism is used to drive the humidification unit to rotate;

[0010] A water tank is located below the humidification unit, with the lower end of the humidification unit immersed in the water tank;

[0011] A water supply tank is located on one side of the housing, and the water supply tank is connected to the water tank via a connecting pipe.

[0012] Furthermore, the housing is provided with a central base, which separates the blower from the humidification unit. A ventilation mesh is provided on the central base, which is connected to the air inlet channel of the blower. The drive mechanism is installed on the central base.

[0013] Furthermore, the humidification unit includes humidifying cotton and a gear mounting base. The humidifying cotton is mounted on the gear mounting base. A rotating shaft is provided on the central base. The center of the humidification unit is connected to the rotating shaft. The driving mechanism includes a driving component and a gear component. The gear component meshes with the gear mounting base. The driving component drives the gear component to rotate the gear mounting base.

[0014] Furthermore, the gear mounting base is provided with several fasteners, which fix the humidifying cotton to the gear mounting base. The humidifying cotton has a honeycomb-shaped circular structure.

[0015] Furthermore, the blower includes an impeller, a volute, and a drive motor. The volute is mounted on the central base, the impeller and the drive motor are located inside the volute, the impeller is mounted on the output shaft of the drive motor, and the air inlet and outlet of the blower are respectively connected to the air inlet and the air outlet to form an air duct.

[0016] Furthermore, the drive unit and the drive motor are both connected via a controller, and the drive unit and the drive motor start synchronously.

[0017] Furthermore, the purification unit is a HEPA filter, which is arranged in a grid pattern.

[0018] Furthermore, the front end of the air inlet is also provided with a front shell, which is spaced apart from the air inlet so that the front of the purification unit stops air intake and air intakes from the gaps on the left and right sides.

[0019] Furthermore, a water level sensor is installed in the water tank. When the water level sensor detects that the water level in the water tank is lower than that of the humidification unit, the controller shuts down the drive unit and the drive motor and issues an alarm.

[0020] Furthermore, the water tank is detachably installed at the bottom of the central base.

[0021] The technical solution provided in this application has the following advantages compared with the prior art:

[0022] The rotary humidification unit and water tank immersion structure of this application directly avoid the traditional risk of clogging by eliminating the water pump spraying mechanism. At the same time, the rotational motion causes the humidifying cotton to be periodically submerged and lifted, significantly increasing the water contact area and improving evaporation efficiency. The layout of the purification unit with the front-mounted blower and rear-mounted fan forces the airflow to purify the dry air before penetrating the moisturizing cotton, preventing the filter from becoming damp and failing. The negative pressure suction of the blower further accelerates the diffusion of water molecules. The two work together to achieve enhanced purification efficiency, doubled humidification capacity, and a leap in system reliability within a compact space. Attached Figure Description

[0033] 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.

[0034] 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.

[0035] For ease of description, spatial relative terms may be used in the 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 device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, 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 device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0036] To address the technical problem of sacrificing humidification efficiency in existing technologies that attempt to combine purification and humidification functions, this application provides a humidifier with integrated purification capabilities. Its rotating humidification unit and water tank immersion structure directly avoid the traditional risk of clogging by eliminating the water pump spraying mechanism. Simultaneously, the rotational motion periodically submerges and lifts the humidifying cotton, significantly increasing the water contact area and improving evaporation efficiency. The front-mounted, rear-mounted airflow arrangement forces airflow to purify dry air before penetrating and wetting the humidifying cotton, preventing the filter from becoming damp and malfunctioning. The negative pressure suction of the airflow further accelerates water molecule diffusion. These two elements work synergistically to simultaneously achieve enhanced purification efficiency, doubled humidification capacity, and a significant leap in system reliability within a compact space.

[0037] Please see Figures 1 to 5 This application provides a humidifier with purification function, comprising: a housing 1, with an air inlet 11 and an air outlet 12 on the housing 1; a purification unit 2, disposed inside the housing 1 and located inside the air inlet 11; a blower 4, disposed inside the housing 1 and located at the air outlet 12; a humidification unit 3, disposed inside the housing 1 and located between the purification unit 2 and the blower 4; a drive mechanism 5 for driving the humidification unit 3 to rotate; a water tank 6, disposed below the humidification unit 3, with the lower end of the humidification unit 3 immersed in the water tank 6; and a water supply tank 7, disposed on one side of the housing 1, and connected to the water tank 6 via a connecting pipe 71.

[0038] Specifically, external air is introduced through the air inlet 11 of the housing 1. The airflow first intercepts particulate pollutants through the purification unit 2 adjacent to the air inlet 11. The purified air continues to flow to the humidification unit 3, at which point the drive mechanism 5 drives the humidification unit 3 to rotate continuously, with its lower end immersed in the water stored in the water tank 6. The rotational motion ensures that the humidifying material is evenly saturated with water. The blower 4, located at the air outlet 12, generates negative pressure, guiding the airflow through the moistened humidification unit 3 and carrying water molecules. Finally, the humidified air is discharged from the air outlet 12. The water supply tank 7 automatically replenishes the consumed water to the water tank 6 through the connecting pipe 71, maintaining a stable water level. The pre-positioning of the purification unit 2 completely avoids water vapor erosion of the filter material, ensuring long-term purification efficiency. At the same time, the rotating humidification unit 3 achieves self-saturation of the humidifying material through periodic immersion-lifting motion, eliminating the risk of clogging caused by traditional water pump spraying.

[0039] like Figure 3-5 As shown, the housing 1 has a central base 13, which separates the blower 4 from the humidification unit 3. A ventilation mesh 131 is provided on the central base 13, which is connected to the air inlet channel of the blower 4. The drive mechanism 5 is installed on the central base 13.

[0040] Specifically, the central base 13 serves as a rigid support frame fixed within the housing 1, completely isolating the blower module 4 from the humidification unit 3 module in space. A ventilation mesh 131, formed on the surface of the central base 13, extends through its body and precisely aligns with the air inlet surface of the blower 4, creating a continuous and unobstructed airflow channel. The drive mechanism 5 is directly and fixedly mounted on the base surface of the central base 13 away from the blower 4, with the central base 13 physically isolating the drive mechanism 5 from the water mist generated by the rotation of the humidification unit 3. The physical separation provided by the central base 13 prevents the diffusion of moisture from the humidification unit 3 to the blower 4 area, completely eliminating the risk of short circuits due to moisture in the motor; it also isolates the dynamic balance of the impeller 42 of the blower 4 from the rotational vibration of the humidification unit 3.

[0041] like Figure 2 and Figure 4As shown, the humidifying unit 3 includes a humidifying cotton 31 and a gear mounting base 32. The humidifying cotton 31 is mounted on the gear mounting base 32. A rotating shaft 132 is provided on the central base 13. The center of the humidifying unit 3 is connected to the rotating shaft 132. The driving mechanism 5 includes a driving component 51 and a gear component 52. The gear component 52 meshes with the gear mounting base 32. The driving component 51 drives the gear component 52 to rotate the gear mounting base 32.

[0042] Specifically, the gear mounting base 32 serves as the rotating carrier of the humidification unit 3, and its outer edge is provided with an annular toothed structure. The humidifying cotton 31 is fixed inside the gear mounting base 32 by snap-fit ​​or adhesive, forming an integrated rotating body. The rotating shaft 132 on the middle base 13 vertically passes through the central hole of the gear mounting base 32, forming a coaxial rotating pair. The output end of the drive component 51 (such as a stepper motor) is connected to the gear component 52. The gear component 52 precisely meshes with the annular toothed structure of the gear mounting base 32. When the drive component 51 is running, it transmits torque to the gear mounting base 32 through the gear component 52, driving the humidifying cotton 31 to rotate uniformly around the axis of the rotating shaft 132. By replacing the traditional belt / coupling structure with this gear meshing transmission, the problem of rotational lag of the humidifying cotton 31 caused by slippage can be eliminated, ensuring that the humidifying cotton 31 is in uniform contact with the airflow throughout its entire area.

[0043] It is understood that the driving component 51 in this embodiment is a motor. In other embodiments, it can also be a magnetic levitation drive rotor, a pneumatic turbine, or other structures. The specific configuration can be made according to the actual situation and is not limited here.

[0044] like Figure 4 As shown, the gear mounting base 32 is provided with several fasteners 321, which fix the humidifying cotton 31 to the gear mounting base 32. The humidifying cotton 31 has a honeycomb-shaped circular structure.

[0045] Specifically, the gear mounting base 32 has multiple fasteners 321 on its surface. The fasteners 321 are snap-fit ​​or threaded locking structures, which clamp and fix the honeycomb-shaped circular humidifying cotton 31 to the surface of the gear mounting base 32 by insertion or tightening. The honeycomb-shaped circular outline of the humidifying cotton 31 perfectly matches the shape of the gear mounting base 32, and its outer edge is evenly pressed and fixed by the fasteners 321, so that the humidifying cotton 31 always remains synchronized with the mounting base without displacement during rotation.

[0046] like Figure 1-2 As shown, the blower 4 includes an impeller 42, a volute 41, and a drive motor 43. The volute 41 is mounted on the central base 13. The impeller 42 and the drive motor 43 are located inside the volute 41. The impeller 42 is mounted on the output shaft 132 of the drive motor 43. The air inlet and air outlet of the blower 4 are connected to the air inlet 11 and the air outlet 12, respectively, to form an air duct 44.

[0047] Specifically, the volute 41 is fixedly installed on the surface of the central base 13 as a ventilation cavity; the drive motor 43 is integrally built into the center of the volute 41; the impeller 42 is directly mounted on the output shaft 132 of the drive motor 43 and rotates coaxially with the shaft 132; the air inlet port of the volute 41 is precisely aligned with the ventilation mesh 131 of the central base 13 to form the air inlet end, and the air outlet port of the volute 41 is connected to the air outlet 12 of the housing 1 to form the air outlet end, together forming a complete air duct 44. The volute 41 constrains the centrifugal airflow generated by the rotation of the impeller 42 into a spiral acceleration air duct 44, which can significantly improve the air pressure and flow velocity, and realize strong wind delivery in a small volume.

[0048] In some embodiments, the drive unit 51 and the drive motor 43 are both connected via a controller, and the drive unit 51 and the drive motor 43 start synchronously.

[0049] Specifically, the controller connects the drive unit 51 and the drive motor 43 via wires. When the user triggers the device start command, the controller synchronously sends an energizing signal to both the drive unit 51 and the drive motor 43, activating the humidification unit 3's rotation and the airflow generation of the blower 4 simultaneously. If either component fails to start, the controller interrupts the operation of the other component. In this way, the humidification response delay of the humidifier approaches zero, achieving a transient efficiency of "humid air output upon startup."

[0050] like Figure 1-2 As shown, purification unit 2 is a HEPA filter, which is arranged in a grid pattern.

[0051] Specifically, the HEPA filter consists of multiple layers of folded filter media, with the crests and troughs of the folds supported and fixed by cross-shaped rigid grid strips. The grid strips are bonded to the edges of the filter media to form an integral frame, dividing the filter surface into a uniform rectangular or diamond grid array.

[0052] like Figure 1-2 As shown, the front end of the air inlet 11 is also provided with a front shell 8, which is spaced apart from the air inlet 11 so that the front of the purification unit 2 stops the air intake and the air intake comes in from the gaps on the left and right sides.

[0053] Specifically, the front shell 8 is installed perpendicular to the outer edge of the air inlet 11 of the shell 1, and the distance between the two forms a through-type lateral air duct 44. The front shell 8 completely blocks the front airflow area of ​​the purification unit 2 (HEPA filter), while equal-width gaps are reserved between the left and right sides of the front shell 8 and the frame of the air inlet 11 of the shell 1. The forced airflow is turned 90° and then horizontally drawn in through the gaps on both sides, directly impacting the left and right wing filter surfaces of the purification unit 2. The front shell 8 physically isolates external foreign objects from directly hitting the front of the purification unit 2, which can prevent structural damage to the filter material caused by particulate matter impact and extend the filter life. The horizontal airflow on both sides simultaneously penetrates the left and right wing areas of the purification unit 2, which greatly improves the utilization rate compared to the traditional single-sided filter element, and at the same time doubles the dust holding capacity.

[0054] In some embodiments, a water level sensor is provided in the water tank 6. When the water level sensor detects that the water level in the water tank 6 is lower than that in the humidification unit 3, the controller shuts down the drive unit 51 and the drive motor 43 and issues an alarm.

[0055] Specifically, the water level sensor is vertically installed on the side wall of the water tank 6, with its detection surface level with the bottom of the humidification unit 3 at the water immersion position. When the water level is lower than the detection surface, the sensor sends an electrical signal to the controller. The controller immediately cuts off the power supply circuit between the drive component 51 and the drive motor 43, and simultaneously triggers the audible and visual alarm to issue a warning signal. By strongly coupling the real-time water level monitoring with the drive system, the risk of mechanical burnout caused by the humidification unit 3 running dry can be eliminated, achieving zero idling damage.

[0056] like Figure 2-5 As shown, the water tank 6 is detachably installed at the bottom of the central base 13.

[0057] Specifically, the bottom of the water tank 6 is equipped with a sliding rail or snap-fit ​​structure that matches the pre-set guide groove or snap-fit ​​position on the bottom of the central base 13; installation is completed by horizontal pushing or vertical pressing, and the locking mechanism is tightened to secure it; during disassembly, the locking mechanism is released, and the water tank 6 can be separated by pulling it out along the sliding rail or lifting the snap-fit. The independent disassembly of the water tank 6 allows for thorough cleaning without dead angles, completely eliminating the dead angles of scale buildup in traditional one-piece structures and preventing sources of bacterial growth.
