Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and particularly relates to a fan. Background Art

[0002] Traditional tower fans are popular for their delicate and natural fan effect. However, in actual applications, the quality of the wind they blow is affected by environmental factors, especially in indoor environments with pollutants such as dust and smoke. These pollutants may reduce the purity of the wind output by the tower fan and cause a series of problems.

[0003] On the one hand, when a tower fan is placed in a room containing dust, smoke and other particulate matter, the fan spreads these pollutants by inhaling them. This not only affects the quality of the wind, but also exposes the human body to harmful gases, because the tower fan inhales pollutants and sends air to the outside, accelerating the speed at which the human body inhales these harmful substances.

[0004] On the other hand, because the air may contain particulate matter such as dust, these particulate matter gradually accumulates inside the tower fan over time, forming a stubborn dust accumulation area, causing the wind blown by the tower fan to gradually become "dirty", which further reduces the quality of the blown wind, provides users with a very poor user experience, and has a negative impact on air quality. In addition, because dust accumulates on the tower fan, it will also affect the aesthetics of the tower fan, further reducing the user experience. Utility Model Content

[0034] The utility model provides a fan, which combines a tower fan assembly with an air purifier assembly, purifies the air sucked into the fan through the air purifier assembly, and then sends the purified air to the tower fan assembly, so that the tower fan assembly can output clean wind to the outside, protect human health, and the air purifier assembly can also prevent dust from adhering to the tower fan assembly, improve the sanitation of the tower fan assembly, and enhance the aesthetics. At the same time, due to the effect of the tower fan assembly, the air circulation in the room is greatly improved, and the unfiltered air can be accelerated to flow into the air purifier, thereby greatly improving the efficiency of filtering air.

[0035] In a typical embodiment of the present invention, Figure 1 and Figure 2 The fan 100 includes a shell 200, a tower fan assembly 300, an air cleaner assembly 400 and a control unit. The tower fan assembly 300, the air cleaner assembly 400 and the control unit are arranged in the shell 200. The control unit is electrically connected to the tower fan assembly 300 and the air cleaner assembly 400 respectively, and the control unit controls the tower fan assembly 300 and the air cleaner assembly 400 to work.

[0036] The housing 200 is a hollow columnar structure, and a receiving cavity 210 is provided in the housing 200, and the receiving cavity 210 is arranged along the axis of the axial direction of the housing 200. An air inlet 220 and an air outlet 230 are provided on the housing 200, and the air inlet 220 and the air outlet 230 are arranged up and down along the axis.

[0037] The air purifier assembly 400 and the tower fan assembly 300 are arranged in the accommodating chamber 210. The tower fan assembly 300 and the air purifier assembly 400 are stacked up and down along the axis. The air purifier assembly 400 is arranged to align with the air inlet 220, and the tower fan assembly 300 is arranged to align with the air outlet 230. External air enters the accommodating chamber 210 through the air inlet 220. The air purifier assembly 400 purifies the air entering the accommodating chamber 210, filters harmful substances and dust in the air, and then outputs the purified air to the tower fan assembly 300. The tower fan assembly 300 increases the flow rate of the purified air, and outputs the air to the outside through the air outlet 230, changes the external temperature, and prevents the user from inhaling harmful substances and dust, thereby protecting the health of the body.

[0038] In this embodiment, combined with Figure 3 and Figure 4 The air purification assembly 400 includes a filter assembly 410 , a wind wheel assembly, a collector 420 and a flow guide diffuser 430 .

[0039] The filter assembly 410 includes a filter screen 411, which has a filtering function and can filter harmful substances and dust in the air to make the air clean. The filter screens 411 are surrounded by the filter assembly 410 to form a hollow structure. Since the filter assembly 410 is a hollow structure, a filter channel 412 is provided in the middle of the filter assembly 410. Preferably, activated carbon is provided in the filter screen 411.

[0040] The filter assembly 410 is aligned with the air inlet 220 so that the external air entering the accommodating chamber 210 through the air inlet 220 first contacts the filter assembly 410, thereby filtering harmful substances and dust in the external air to make the air clean. In order to facilitate the distinction between the air filtered by the filter assembly 410 and the external air, the air filtered by the filter assembly 410 is called clean air.

[0041] Because the filter assembly 410 is a hollow structure, the air inlet 220 can be set to a ring structure accordingly, so that the area of ​​the air inlet 220 is expanded and the air intake volume is increased while the total volume remains unchanged, so that the filter assembly 410 can improve the air filtering efficiency per unit time. Moreover, because the filter assembly 410 is a hollow structure, the external air entering the accommodating chamber 210 from the air inlet 220 needs to pass through the filter net 411 of the filter assembly 410 to enter the filter channel 412 of the filter assembly 410, regardless of the flow angle of the air, and flow to the tower fan assembly 300 through the filter channel 412.

[0042] Combination Figure 1 The air inlet 220 is an annular structure, that is, a ring-shaped gap-shaped air inlet 220 is provided on the housing 200. In order to maintain the structural stability of the housing 200, a screen 240 is provided at the air inlet 220. The air inlet 220 is filled with the screen 240, so that the housing 200 maintains structural stability. The screen 240 is provided with a plurality of air inlet holes, so that external air can enter the accommodating chamber 210 through the air inlet holes, and the screen 240 can prevent large objects, such as small stones, from entering the accommodating chamber 210.

[0043] Combination Figure 3 The collector 420 and the filter assembly 410 are stacked up and down along the axis, and combined with Figure 5 The collector 420 is provided with an annular air duct 421, and the annular air duct 421 is arranged inside the collector 420. The annular air duct 421 is connected to the filter channel 412, so that the clean air in the filter channel 412 flows into the annular air duct 421.

[0044] Combination Figure 4 The wind wheel assembly includes a wind wheel 441 and a first motor 442. The first motor 442 is linearly connected to the wind wheel 441 through an output shaft. The control unit controls the first motor 442 to work, so as to drive the wind wheel 441 to rotate, thereby driving the clean air in the annular air guide duct 421 to flow toward the tower fan assembly 300. In this embodiment, the wind wheel assembly is further provided with a mounting structure 443, the mounting structure 443 is fixedly connected to the housing 200, and the first motor 442 is fixedly connected to the mounting structure 443.

[0045] Specifically, combined Figure 7 and Figure 8The wind wheel 441 is disposed in the annular air duct 421 or above the annular air duct 421. In this embodiment, the wind wheel 441 is disposed in the annular air duct 421. The wind wheel 441 rotates to drive the clean air in the annular air duct 421 to flow quickly toward the tower fan assembly 300, and at the same time drives the clean air in the filter channel 412 to flow quickly into the annular air duct 421, so that the external air can also quickly enter the filter channel 412 through the air inlet 220, thereby improving the air intake and filtering efficiency. In this embodiment, the wind wheel 441 is provided with a plurality of blades, and the speed of stirring the air flow is increased by the plurality of blades.

[0046] In one embodiment, in combination Figure 4 and Figure 8 The collector 420 is also provided with a protective net 422 at the bottom of the annular air duct 421 , and the protective net 422 is used to prevent foreign matter from entering the annular air duct 421 , thereby improving the safety of the fan 100 .

[0047] In a typical embodiment of the utility model, the wind wheel 441 is conveniently arranged in the annular air guide duct 421 to increase the flow rate of the clean air. Figure 5 , the annular air guide duct 421 is divided into a first air guide section 4211, a second air guide section 4212 and a third air guide section 4213, and the first air guide section 4211, the second air guide section 4212 and the third air guide section 4213 are sequentially connected from bottom to top along the axis. Among them, the inner diameter of the first air guide section 4211 is smaller than the inner diameter of the third air guide section 4213, and the second air guide section 4212 transitionally connects the first air guide section 4211 and the third air guide section 4213. The first air guide section 4211 is connected to the filter channel 412, so that the clean air in the filter channel 412 can directly flow into the annular air guide duct 421.

[0048] Combination Figure 5 and Figure 8 The wind wheel 441 extends from the third wind guide section 4213 to the first wind guide section 4211 from top to bottom along the axis. A first air inlet gap 423 is formed between the wind wheel 441 and the first wind guide section 4211, a second air inlet gap 424 is formed between the wind wheel 441 and the second wind guide wheel 441, and a third air inlet gap 425 is formed between the wind wheel 441 and the third wind guide section 4213.

[0049] When the wind wheel 441 rotates driven by the first motor 442, the clean air in the filter channel 412 is driven by the wind wheel 441 to flow toward the tower fan assembly 300 along the first air inlet gap 423, the second air inlet gap 424, and the third air inlet gap 425. Moreover, since the first air inlet gap 423, the second air inlet gap 424, and the third air inlet gap 425 are relatively small in volume, the pressure of the clean air entering the air inlet duct will be increased, thereby increasing the flow rate of the clean air, so that the tower fan assembly 300 can quickly deliver air to the outside.

[0050] Combination Figure 5 , the inner side surface of the second air guide section 4212 is an arc surface, so that the first air guide section 4211 and the third air guide section 4213 are connected by an arc surface transition. Because the inner side surface of the second air guide section 4212 is an arc surface, the clean air will be forced to change the flow angle when flowing from the first air guide section 4211 to the third air guide section 4213, so as to further increase the pressure of the clean air, thereby increasing the flow rate of the clean air, so that the clean air can further flow to the tower fan assembly 300 quickly. By setting the annular air guide duct 421, the air near the air inlet 220 can be quickly inhaled, and a certain negative pressure is formed in the annular air guide duct 421, so that the outside air can quickly flow into the filter assembly 410, thereby increasing the intake rate of the outside air.

[0051] Moreover, the clean air flowing out of the second air guiding section 4212 has strong rotational properties, which can increase the speed of the clean air in the second air guiding section 4212 in the rotational flow, so as to reduce the viscosity loss of the airflow to the annular air guiding duct 421, thereby increasing the pressure of the clean air.

[0052] Combination Figure 3 and Figure 6 The flow guide diffuser 430 is disposed on the flow collector 420 along the axis, and the flow guide includes a flow guide 431 and a flow divider 432 .

[0053] Combination Figure 8 A guide channel 440 is formed between the outer side of the guide body 431 and the inner side of the accommodating chamber 210, and the clean air flows out of the third air inlet gap 425 and enters the guide channel 440. In this embodiment, the guide body 431 is a columnar structure, and the outer side of the guide body 431 guides the clean air to flow toward the tower fan assembly 300.

[0054] Combination Figure 6The diverter body 432 includes a diverter ring 4321 and a plurality of diverter sheets 4322. The diverter ring 4321 is sleeved on the bottom of the guide body 431. The diverter sheet 4322 is disposed between the diverter ring 4321 and the guide body 431. The diverter sheet 4322 connects the diverter ring 4321 and the guide body 431. The plurality of diverter sheets 4322 are sequentially disposed along the annular path of the diverter ring 4321. After the clean air flows out of the annular air guide duct 421, it is diverted by the plurality of diverter rings 4321, so that the clean air is divided into a plurality of air streams. The plurality of air streams enter the guide duct 440 respectively, and finally flow to the tower fan assembly 300.

[0055] In a typical embodiment of the present invention, Figures 1 to 3 The tower fan assembly 300 includes a crossflow fan assembly and a wind distribution net 320. The crossflow fan assembly is aligned with the air outlet 230, and the crossflow fan assembly accelerates the clean air output by the air purification assembly 400 to form wind, and outputs the wind to the outside of the fan 100 through the air outlet 230.

[0056] Combination Figure 4 and Figure 8 The cross-flow fan assembly includes a fan body 311 and a second motor 312. The output shaft of the second motor 312 is drivingly connected to the fan body 311. The second motor 312 is controlled by the control unit. The second motor 312 rotates to drive the fan body 311 to rotate. The fan body 311 drives the clean air output by the air purification assembly 400 to accelerate the flow to increase the flow rate and form wind. Then the wind is output to the outside of the fan 100 through the air outlet 230.

[0057] In this embodiment, combined with Figure 6 and Figure 8 A blind hole 4311 is provided in the flow guide 431, and the opening of the blind hole 4311 faces the fan body 311. The second motor 312 is arranged in the blind hole 4311 to facilitate the installation of the second motor 312, saving the installation space of the flow guide 431, so as to facilitate the miniaturization of the fan 100.

[0058] Combination Figure 2 and Figure 3 The wind balancing net 320 is a sheet structure, and a number of meshes are provided on the wind balancing net 320. The wind balancing net 320 is arranged on the outside of the fan body 311, and the wind balancing net 320 is bent around the axis with the axis as the axis to semi-enclose the fan body 311, so that the wind balancing net 320 forms a semi-enclosed structure. The wind balancing net 320 of the semi-enclosed structure forms an opening, and the opening is aligned with the air outlet 230. Preferably, the cross-section of the wind balancing net 320 is an arc-shaped structure.

[0059] An air duct 330 is formed between the air duct net 320 and the inner wall of the housing 200. The clean air flows into the air duct 330 along the guide diffuser 430, and then flows from the air duct 330 to the fan body 311 through the mesh of the air duct net 320. Due to the high-speed rotation of the fan body 311, the clean air in the air duct 330 will flow through the air duct net 320 to form a low-speed airflow; then enter the low-speed airflow and flow into the fan body 311. Under the high-speed rotation of the fan body 311, the low-speed airflow will be accelerated to a high-speed airflow, and then blown out from the air outlet 230.

[0060] Moreover, the high-speed airflow blown out by the fan body 311 will accelerate the flow of the surrounding air, disturb the external air to flow toward the air inlet 220, accelerate the filtering of the external air, filter out harmful substances and dust in the external air, and purify the air.

[0061] In this embodiment, combined with Figure 1 and Figure 2 The air outlet 230 is provided with an air outlet grille 250, and the high-speed airflow blown out through the fan body 311 will be cut by the air outlet grille 250 to form multiple uniform winds to reduce the external temperature. The wind blown out by the fan body 311 does not contain harmful substances and dust, thereby protecting human health.

[0062] In one embodiment, the air cleaner assembly 400 is coaxially disposed with the tower fan assembly 300 .

[0063] To sum up, the fan of the utility model purifies the inhaled air by setting an air purification component, and then outputs the purified air to the tower fan component, so that the tower fan component can output the purified wind to the outside, so as to improve the user's health and enhance the user experience.
