Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with a humidification function. Background Technology

[0002] In modern life, fans are a common household appliance. Driven by an electric motor, they rotate blades to accelerate air circulation, bringing coolness to people in hot weather. Widely used in homes, offices, commercial spaces, and other settings, they are important devices for cooling off and improving air circulation in summer. However, the function of fans is relatively limited. Their cooling effect mainly relies on airflow to accelerate the evaporation of sweat from the body. In hot and dry environments, relying solely on fans is insufficient to effectively alleviate the heat and provide a comfortable experience.

[0003] At the same time, humidifiers, another common household appliance, can increase indoor air humidity and effectively improve problems such as dry skin and respiratory discomfort caused by dry air. Especially in dry seasons or regions, and when indoor air humidity decreases due to the use of air conditioners, heaters, and other equipment, humidifiers play a vital role in creating a healthy and comfortable indoor environment.

[0004] Given the respective functional characteristics of fans and humidifiers, and in order to meet people's higher pursuit of a comfortable environment, this utility model provides a fan with a humidification function. This fan aims to disperse the water mist generated by the humidifier into the air through the fan's airflow, achieving simultaneous operation of blowing and humidification functions. The humid air blown out by the fan can not only alleviate the discomfort caused by the dry environment, but also increase the cooling sensation of the fan's airflow, thereby providing users with a cool and humid user experience in hot and dry environments, and improving human comfort.

[0008] Preferably, the humidification assembly further includes: a water tank, a water inlet pipe, a DC fan, and an atomizer. The water tank is divided into a water storage chamber and an atomizer chamber by a partition.

Detailed Implementation

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] This utility model discloses a fan with a humidification function, such as Figures 1-8 As shown, the fan with humidification function in this embodiment includes: a housing 100, a blower assembly 200 and a humidification assembly 300 disposed inside the housing 100, and a first air outlet 100a and at least one air inlet 100b provided on the housing 100 at a position corresponding to the surface of the blower assembly 200. In this embodiment, the first air outlet 100a is located on the front side of the fan with humidification function, and the humidification assembly 300 includes a steam outlet 340 for transmitting water mist to the air outlet. In this embodiment, the air outlet of the steam outlet 340 is located above the first air outlet 100a. In use, first, add an appropriate amount of water to the water tank 310 of the humidification component 300; then, simultaneously turn on the blower component 200 and the humidification component 300. The impeller 210 of the blower component 200 rotates and continuously outputs airflow from the first air outlet 100a. The atomizer of the humidification component 300 continuously generates water mist. The water mist is transmitted to the first air outlet 100a through the steam outlet 340, and then mixes with the airflow generated by the blower component 200 to form an airflow with water mist, which not only increases the humidity of the air, but also enhances the cooling sensation of the airflow.

[0027] This utility model provides a fan with a humidification function. Its working principle is that the blower assembly 200 draws in air from the air inlet and blows it out from the first air outlet 100a to form an airflow. At the same time, the water mist generated by the humidification assembly 200 is transmitted through the steam outlet 340 to the first air outlet 100a and mixes with the airflow. Finally, the airflow carrying water mist is discharged, realizing the synergistic effect of blowing and humidifying. Compared with traditional fans, it can replenish air humidity while accelerating air circulation and cooling, avoiding skin and respiratory discomfort caused by dry environment. It can also save placement space, make moisture diffusion more even, improve the overall air comfort, and has both convenience and practicality.

[0028] In one embodiment, such as Figure 1 , Figure 2As shown, the outer casing 100 includes a front casing 110, a rear casing 120, a base 130, and a top cover 140. The front casing 110 and the rear casing 120 are connected to each other by snap-fit ​​and to the base 130 by bolts. The top cover 140 is bolted to the top of the front casing 110 and the rear casing 120, and the top cover 140 has a water inlet 140a. The outer casing 100 can be disassembled into four parts, each of which can be prefabricated and reassembled individually, making it suitable for mass production. This not only reduces the difficulty of product assembly but also allows for targeted adjustments when a specific part of the outer casing 100 needs to be changed, improving production flexibility, significantly reducing production costs, and increasing the product update rate. Simultaneously, the bolted connection makes the outer casing 100 easy to disassemble and maintain internal components, and the water inlet 140a on the top cover 140 makes adding water more convenient, enhances the overall structural stability, and facilitates future functional expansion.

[0029] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 As shown, the blower assembly 200 includes: an impeller 210, a left air duct 220 and a right air duct 230 respectively disposed on both sides of the impeller 210 and connected to the impeller 210. The left air duct 220 and the right air duct 230 form a second air outlet 200a on the front side of the impeller 210 and are connected to the first air outlet 100a. The second air outlet 200a is provided with an air outlet screen 240. The left air duct 220 and the right air duct 230 are respectively disposed on both sides of the impeller 210, so that air enters the interior of the impeller 210 through two independent channels and finally converges on the front side of the impeller 210. The left air duct 220 and the right air duct 230 form the second air outlet 200a here. The second air outlet 200a is connected to the first air outlet 100a of the outer casing 100, forming an airflow path of "dual air duct air intake → impeller → convergence to the second air outlet → introduction into the first air outlet". The dual-duct design (left and right ducts) guides the impeller 210 intake more efficiently, reducing turbulence and losses during airflow transmission and concentrating the airflow. The converging airflow from both ducts exits through the second outlet 200a, resulting in a more uniform airflow distribution and preventing localized issues of excessively strong or weak airflow. When the uniform airflow enters the first outlet 100a from the second outlet 200a, it mixes more thoroughly with the water mist transmitted from the humidification component 300 to the first outlet 100a via the steam outlet 340. This ensures a more even distribution of water mist within the airflow, preventing localized high (leading to water droplets on the airflow) or low (poor humidification) concentrations and improving humidification uniformity. The air outlet 200a is equipped with an air outlet mesh 240 that can effectively prevent fingers, hair or other foreign objects from entering the air duct and coming into contact with the high-speed rotating impeller 210, reducing safety hazards. At the same time, the air outlet mesh 240 can also re-sort the airflow, making the blown air softer and improving user comfort.

[0030] In one embodiment, such as Figure 2 , Figure 5 , Figure 6 As shown, the humidification assembly 300 also includes: a water tank 310, a water inlet pipe 320, a DC fan 330, and an atomizer. The water tank 310 is provided with a partition 311 that divides the water tank 310 into a water storage chamber 310a and an atomizer chamber 310b that are connected to each other. One end of the water inlet pipe 320 is connected to the water inlet 140a and the other end is connected to the water storage chamber 310a. The steam outlet 340 is connected to the atomizer chamber. The atomizer is located in the atomizer chamber 310b. The DC fan 330 is connected to the atomizer chamber 310b through a pipe. The DC fan 330 is used to deliver gas to the atomizer chamber 310b to increase the internal pressure of the atomizer. The water tank 310 is divided into a water storage chamber 310a and an atomizer chamber 310b by a partition 311. The water storage chamber 310a is used for storing a large amount of stable water, while the atomizer chamber 310b serves as the core area for the atomization reaction. The amount of water entering the atomizer chamber 310b remains constant each time. The two chambers are independent yet interconnected, ensuring that the water storage chamber 310a can continuously supply water to the atomizer chamber 310b, while preventing backflow of water mist during atomization from affecting the cleanliness of the stored water. A DC fan 330 connected to the atomizer chamber 310b is installed on the water tank 310. Gas is delivered into the atomizer chamber 310b through a pipe, which replenishes and increases the air pressure inside the atomizer chamber 310b. This pressure allows the water mist generated by the atomizer to be delivered more efficiently through the steam outlet 340 to the first air outlet 100a, enhancing the mixing effect of water mist and airflow. Water inlet pipe 320 is directly connected to water inlet 140a on top cover and water storage chamber 310a, forming an independent water replenishment channel. This allows water to be directly replenished to water storage chamber 310a without disassembling any parts, and the water replenishment process does not interfere with the normal operation of atomizer chamber 310b.

[0031] In one embodiment, such as Figure 1 , Figure 2 As shown, the area near the water inlet 140a of the top cover 140 is recessed downwards to form a funnel-shaped water inlet 140a. In this embodiment, the funnel-shaped water inlet 140a uses the inclined inner wall of the funnel to guide the water flow, so that the injected water naturally converges to the water inlet 140a under the action of gravity, reducing the possibility of water overflow. On the one hand, the funnel structure can provide clear positioning guidance for water filling operation, and users can easily add water without precisely aligning the water inlet 140a, improving the convenience of operation; on the other hand, the recessed design can prevent the water flow from spreading to the surroundings, avoiding water from spilling on the surface of the top cover 140 when adding water, reducing the trouble of moisture on the outer shell or cleaning by the user, and at the same time, it can also allow the water flow to enter the water tank 310 more concentratedly through the water filling pipe 320, improving the water filling efficiency.

[0032] In one embodiment, such as Figure 1 , Figure 2As shown, a baffle 141 is provided on the water inlet 140a, and a support foot protrudes from the lower surface of the baffle 141. The support foot is fixedly connected to the surface of the water inlet 140a. In this embodiment, there are four support feet. In other embodiments, the number of support feet can be one, two, three, or set according to actual conditions. By covering the water inlet 140a with the baffle 141, the physical barrier effect of the baffle 141 prevents external dust, hair, and other foreign objects from falling directly into the water inlet 140a, avoiding impurities from entering the water storage chamber 310a and contaminating the water or clogging the water inlet pipe 320. The baffle 141 is fixed to the surface of the water inlet 140a by the support foot on its lower surface, so that a certain gap is formed between the baffle 141 and the water inlet 140a (the height of the support foot determines the size of the gap). This ensures the stable installation of the baffle 141 without affecting the flow of water into the water inlet 140a through the gap during water injection.

[0033] In one embodiment, such as Figure 1 , Figure 2 As shown, the front casing 110 includes: a front wall panel 111, two side wall panels 112 disposed opposite each other on both sides of the front wall panel 111, a first air outlet 100a disposed on the front wall panel 111, and a plurality of air inlets 100b evenly spaced on the side wall panels 112, forming an array of air inlets 110b. The array of air inlets 100b on the two side wall panels 112 utilizes the openness of the side wall panels 112 to reduce spatial obstruction during air intake. The distributed design increases the total air intake area, while the evenly distributed structure allows airflow to smoothly enter the left air duct 220 and right air duct 230 from multiple directions, avoiding localized air intake congestion. In the array design, the size of a single air inlet 110 can be appropriately reduced (while maintaining the total area). Combined with the evenly spaced layout, this reduces the risk of fingers or large foreign objects entering the casing 100 through the air inlets and contacting the impeller 210, improving safety during use.

[0034] In one embodiment, such as Figure 1 , Figure 2 , Figure 7 As shown, an air outlet grille 150 is provided at the first air outlet 100a, and the air outlet grille 150 includes several rotatable vanes 151. The rotatable vanes 151 can guide the airflow blown from the first air outlet 100a by changing their own rotation angle. When the vanes 151 rotate in the same direction, the airflow direction can be concentrated and changed; when the vanes 151 rotate at different angles, the airflow range can be diffused or focused. In addition, the overall structure of the air outlet grille 150 can prevent foreign objects (such as fingers, small objects, etc.) from entering the interior of the air outlet 100a, avoiding contact with internal components such as the blower assembly 200, and also reducing the direct entry of dust and other impurities into the air duct.

[0035] In one embodiment, such as Figure 7As shown, several oscillating blades 151 are connected by connecting rods 152, which simultaneously control the oscillation direction of the oscillating blades 151. The connecting rods 152 are fixedly connected to each oscillating blade 151. When the connecting rods 152 are displaced by an external force (manual pushing or motor driving), they cause all connected oscillating blades 151 to rotate simultaneously around their own rotation axis, achieving consistent adjustment of the oscillation direction of the oscillating blades 151. The rigid connection of the connecting rods 152 ensures that all oscillating blades 151 always maintain the same angle, avoiding airflow disturbance caused by loosening or misalignment of a single oscillating blade 151, and allowing the blown airflow to be precisely focused on the target area.

[0036] In one embodiment, such as Figure 8 As shown, a load-bearing plate 400 is provided horizontally inside the outer casing 100. The load-bearing plate 400 is fixedly connected to the side wall panels 112. The load-bearing plate 400 is used to place the blower assembly 200 or the humidifier assembly 300. Both the blower assembly 200 and the humidifier assembly 300 have a certain weight. If they are placed directly on top of each other, it may cause excessive local stress, which may lead to deformation of the blower assembly 200 or the humidifier assembly 300 over time (depending on which assembly is on the bottom). By fixing the load-bearing plate 400 to the side wall panels 112, the weight is distributed to the side wall panels 112, improving the durability of the blower assembly 200 or the humidifier assembly 300. In particular, the blower assembly 200 will vibrate during operation. If the blower assembly 200 is placed directly on the humidifier assembly 300, it will accelerate the deformation rate of the humidifier assembly 300. Using the load-bearing plate 400 can effectively avoid this situation.

[0037] The aforementioned fan with humidification function utilizes a blower assembly and a humidification assembly within its casing. The blower assembly draws in air from the air inlet and blows it out from the first air outlet to form an airflow. Simultaneously, the water mist generated by the humidification assembly is transported through the steam outlet to the first air outlet and mixes with the airflow before being discharged. This achieves a synergistic effect of blowing air and humidifying. Compared to traditional fans, it can enhance the cooling sensation, accelerate air circulation and cooling, while replenishing air humidity, avoiding skin and respiratory discomfort caused by dry environments. It also saves placement space, allows for more even moisture diffusion, and improves overall air comfort, combining convenience and practicality.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
