Description

Technical Field

[0001] This application relates to the field of humidifiers, and more particularly to a humidifier fan. Background Technology

[0002] Humidifiers and fans are popular because they replenish air humidity while providing ventilation and cooling.

[0003] However, in existing humidifier fans, the mist sprayed from the nozzle is easily drawn back by the airflow generated during fan operation, forming water mist that accumulates on the fan blades. This water mist accumulation not only makes the fan blade surface damp and can cause cleaning problems over time, but more importantly, it directly interferes with the normal spray diffusion path and range of the nozzle, preventing the mist, which should be evenly distributed in the air, from effectively spreading. Ultimately, this significantly reduces the humidification effect of the humidifier fan, making it difficult to fully realize the device's functional value and negatively impacting the user experience.

[0004] The above issues need to be addressed. Utility Model Content

[0005] The purpose of this application is to provide a portable fan to solve the problem in the prior art where the mist sprayed from the nozzle of a humidifier fan is easily drawn back by the airflow generated during the operation of the fan, thus forming water mist and accumulating on the fan blades.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] In a first aspect, this application provides a humidifier fan, comprising:

[0008] Fan base;

[0009] The housing is rotatably connected to the fan base via a drive assembly;

[0010] The fan body is mounted on the machine body;

[0011] A humidification component is installed inside the machine body, and the humidification component includes a water tank, a humidification chamber, and a mist outlet.

[0012] The mist nozzle is located at the outermost edge of the fan body, and its outlet faces the airflow direction of the fan body.

[0013] Furthermore, along the air outlet direction, the vertical distance between the outermost edge of the fan body in the air outlet direction and the highest point of the mist outlet is not less than 25mm.

[0014] Furthermore, the extended axis of the mist outlet has an angle with the rotating axis of the fan body.

[0015] Furthermore, the bottom of the water tank is provided with a water outlet and a water tank cover for sealing the water outlet;

[0016] The humidification tank is located below the water tank and has an upward-protruding top column inside;

[0017] When the water tank is installed inside the machine body, the top column opens the water tank cover to allow the water in the water tank to flow into the humidification tank.

[0018] Furthermore, the humidification tank is provided with a mist outlet channel and a vibrating mist outlet plate. The inlet of the mist outlet channel is located inside the humidification tank, and the vibrating mist outlet plate is provided at the inlet. The outlet of the mist outlet channel constitutes the mist outlet nozzle.

[0019] Furthermore, a water detection component is provided at the bottom of the humidification tank, and the water detection component is electrically connected to the electronic control board located in the body.

[0020] Furthermore, the humidification component also includes a fan;

[0021] The fan is positioned perpendicular to the vibration direction of the vibrating mist-emitting fins.

[0022] Furthermore, the drive assembly includes a motor and a first gear that is drively connected to the output shaft of the motor;

[0023] The fan base is provided with a second gear, and the first gear meshes with the second gear. The first gear rotates planetarily around the second gear under the drive of the motor.

[0024] Furthermore, the side of the casing facing the fan body has a mounting groove, and the fan body has a mounting base, which is fastened to the mounting groove.

[0025] The technical solutions provided in this application have the following advantages compared with the prior art:

[0026] This application provides a portable fan that primarily addresses the problem in existing humidifier fans where the mist sprayed from the nozzle is easily drawn back into the fan, causing water mist to accumulate on the fan blades and thus affecting the spraying effect. Specifically, by setting the outlet direction of the mist nozzle to align with the airflow direction of the fan body and positioning it in front of the fan body's airflow path, a spatial layout is created where the mist outlet direction and airflow direction are coordinated. Structurally, this avoids direct contact between the mist and the fan's suction area. When the fan body operates and generates airflow, the mist sprayed from the nozzle is carried forward by the airflow, reducing the chance of the mist contacting the fan's suction area and effectively preventing the mist from being drawn back into the fan blades. This technical solution effectively solves the problem of mist being drawn back into the fan and accumulating on the fan blades, ensuring that the mist can diffuse smoothly and effectively into the air, thus improving the humidification effect and performance of the humidifier fan.

Detailed Implementation

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In order to solve the problem in existing humidifier fans where the mist sprayed from the nozzle is easily drawn back by the airflow generated by the fan during operation, thus forming water mist and accumulating on the fan blades, affecting the user experience.

[0042] This application provides a humidifier fan, such as Figure 1 and Figure 2 As shown, it includes: a fan base 1; a body 2, which is rotatably connected to the fan base 1 via a drive assembly 5; and a fan body 3, which is mounted on the body 2.

[0043] Specifically, the side of the body 2 facing the fan body 3 has a mounting groove 21, and the fan body 3 has a mounting base, which is fastened to the mounting groove 21.

[0044] During installation, align the mounting base of the fan body 3 with the mounting slot 21 of the casing 2 and apply pressure to secure them together. To disassemble, apply force in the opposite direction to separate the mounting base from the mounting slot 21, thus removing the fan body 3 from the casing 2. This design simplifies the installation and disassembly process of the fan body 3 and casing 2, making it convenient for users to clean, maintain, or replace the fan body 3, thereby solving the problem of inconvenient installation and disassembly of the fan body 3 and casing 2.

[0045] Furthermore, when the fan body 2 can rotate relative to the fan base 1 under the action of the drive component 5, the fan body 3 also rotates synchronously with the fan body 2 relative to the fan base 1, so as to solve the problem in the prior art that the fan body 3 rotates with a higher center of gravity than the fan body 2, which easily causes swaying.

[0046] like Figure 3As shown, the drive assembly 5 includes a motor 51 and a first gear 52 that is driven by the output shaft of the motor 51; a second gear 11 is provided on the fan base 1, and the first gear 52 is meshed with the second gear 11. Under the drive of the motor 51, the first gear 52 rotates around the second gear 11 in a planetary manner. Since the first gear 52 and the motor 51 are located on the side of the body 2, while the second gear 11 is located on the side of the fan base 1, when the motor 51 is powered on and outputs power, it drives the first gear 52 to rotate around the second gear 11 in a planetary manner, thereby realizing the flexible rotation of the body 2 relative to the fan base 1, and thus achieving the purpose of automatically rotating and expanding the air supply area.

[0047] Furthermore, because the output shaft of motor 51 rotates at a relatively high speed, the first gear 52 connected to the output shaft also rotates at a relatively high speed. Therefore, setting the number of teeth of the second gear 11 to be greater than the number of teeth of the first gear 52 can increase the output torque of the output shaft, thereby reducing the speed of the output shaft. This allows the body 2 and the fan base 1 to rotate at a suitable low speed, avoiding the shaking and noise caused by high-speed rotation.

[0048] like Figure 4 As shown, a humidification component 4 is also provided inside the body 2. The humidification component 4 includes a water tank 41, a humidification trough 42 and a mist outlet 43. The mist outlet 43 is located at the outermost edge D of the fan body 3, and its outlet 442 faces the air outlet direction of the fan body 3.

[0049] When the fan body 3 operates and generates an airflow, the mist sprayed from the mist nozzle 43 is carried forward and diffused by the airflow. It should be understood that when the fan is blowing air, the airflow at its outermost edge D is relatively weak. By positioning the outlet 442 of the mist nozzle at the outermost edge D of the fan body 3, the mist is carried forward by the main airflow before reaching the fan edge, reducing the possibility of it being sucked back by the reverse airflow at the edge. In this way, the airflow from the fan pushes the mist along the direction of airflow, preventing the mist from being sucked back onto the fan blades, ensuring that the mist can effectively diffuse into the air, and improving the humidification effect of the humidifier fan.

[0050] Furthermore, along the direction of airflow, such as Figure 1 As shown, the vertical distance between the outermost edge D of the fan body 3 in its airflow direction and the highest point H of the mist nozzle 43 is not less than 25mm. At this distance, the backflow generated by the fan is significantly weakened before reaching the mist nozzle 43, and cannot form an effective reverse suction force on the mist sprayed from the mist nozzle 43, so that the mist can spread smoothly forward under the drive of the airflow, and the spraying effect can be maintained stably.

[0051] Furthermore, such as Figure 1As shown, the extended axis F1 of the mist nozzle 43 has an angle α with the rotating axis F of the fan body.

[0052] It should be understood that this design can expand the coverage area of ​​the spray. The extension line F1 of the center of the mist nozzle 43 is set at an angle α with the rotation axis F of the fan body 3, which changes the initial spray direction of the mist. Preferably, the angle α is between 30° and 80°. When the fan is working, the mist droplets with lateral initial velocity are carried by the high-speed airflow, and their final trajectory is the vector combination of their own initial velocity and the airflow velocity, causing the mist droplets to diffuse to the side and forward.

[0053] In some embodiments, the highest point H of the outlet 442 of the mist nozzle 43 is located below the rotating shaft F of the fan body 3. This design utilizes the physical property of the mist rising naturally after it is ejected, so that its rising path intersects with the airflow of the fan in the area in front of the fan, thereby ensuring that the mist can be fully captured by the airflow and blown far away, avoiding accumulation or settling near the fan body 3.

[0054] Furthermore, such as Figure 5 and Figure 6 As shown, to solve the problem of easy water leakage at the joint between the water tank 41 and the humidification tank 42, the bottom of the water tank 41 is provided with a water outlet 411 and a water tank cover 412 for sealing the water outlet 411; the humidification tank 42 is located below the water tank 41, and has an upwardly protruding top column 421 inside; when the water tank 41 is installed in the body 2, the top column 421 pushes open the water tank 41 cover to allow the water in the water tank 41 to flow into the humidification tank 42.

[0055] In detail, the water tank 41 has a water outlet 411 and a water tank cover 412 at the bottom to close the water outlet 411. The humidification tank 42 is located below the water tank 41 and has an upwardly protruding top column 421 inside, forming a compatible water supply structure. When the water tank 41 is installed inside the body 2, the top column 421 will exert an upward pushing force on the water tank cover 412, opening the water tank cover 412 and allowing the water in the water tank 41 to flow into the humidification tank 42 under the action of gravity. When the water tank 41 is removed, the water tank cover 412 automatically closes the water outlet 411 under its own weight or elastic force to prevent water leakage. This achieves automatic and controllable water supply from the water tank 41 to the humidification tank 42, which is convenient to operate and effectively reduces the occurrence of water leakage, improving the convenience and reliability of the equipment.

[0056] Furthermore, the humidification tank 42 is equipped with a mist outlet channel 44 and a vibrating mist outlet plate 45. The inlet 441 of the mist outlet channel 44 is located inside the humidification tank 42, and the vibrating mist outlet plate 45 is located at the inlet 441. The outlet 442 of the mist outlet channel 44 forms the mist outlet nozzle 43. This design, with the inlet 441 of the mist outlet channel 44 located inside the humidification tank 42 and the outlet 442 forming the mist outlet nozzle 43, provides a dedicated mist outlet channel 44 for mist extraction. This avoids the situation where the mist, due to its light physical characteristics, would not be able to reach the outlet 442 in an orderly manner without the outlet channel 44. When the vibrating mist outlet plate 45 is energized, it vibrates to atomize the water and produce mist. The mist, under its own diffusion and possible airflow, enters the mist outlet channel 44 from the inlet 441 and is then sprayed out to the outside through the outlet 442 of the mist outlet nozzle 43. This design allows the mist generated in the humidification tank 42 to be extracted efficiently and orderly, forming a stable and continuous spray.

[0057] When the water level in the humidification tank 42 is low, the vibrating mist output plate 45 continues to operate to prevent the vibrating mist output plate 45 from burning out. A water detection component 46 is also provided at the bottom of the humidification tank 42. The water detection component 46 is electrically connected to the electronic control board located in the body 2. The electronic control board is electrically connected to the vibrating mist output plate 45.

[0058] It should be understood that the water detection component 46 at the bottom of the humidification tank 42 is electrically connected to the electronic control board and the vibrating mist output plate 45 in the main body 2, forming a water volume detection and control circuit system. The water detection component 46 detects the water volume in the humidification tank 42 in real time. When insufficient water is detected, a signal is transmitted to the electronic control board. Upon receiving the signal, the electronic control board controls the vibrating mist output plate 45 to stop working, preventing it from operating in a waterless state. This design effectively protects the vibrating mist output plate 45, extends its service life, avoids the safety hazards that may be caused by dry burning, and improves the safety and reliability of the equipment.

[0059] Furthermore, in order to ensure that the mist generated by the vibrating plate can flow more effectively along the mist outlet channel 44 to the outlet 442, the humidification assembly 4 also includes a fan 47; the fan 47 is positioned perpendicular to the vibration direction of the vibrating mist outlet plate 45.

[0060] In other words, the fan 47 is located on one side of the vibrating plate. When the fan 47 is working, the airflow generated can create a lateral thrust on the fog generated by the vibrating plate, causing the fog to enter the fog outlet channel 44 faster and more concentrated, and then be sprayed out from the outlet 442 of the spray nozzle, which effectively improves the diffusion speed and discharge efficiency of the fog.
