Description

Technical Field

[0001] The present invention relates to the technical field of environmentally friendly fans, and in particular to an environmentally friendly fan. Background Art

[0002] The core of environmentally friendly fans is the use of advanced energy-saving drive systems, such as brushless DC motors and intelligent frequency conversion technology, which enable the fan to provide strong wind while significantly reducing energy consumption. In addition, by optimizing the fan blade design and aerodynamic principles, low noise and high air volume are achieved, bringing users a more comfortable experience.

[0003] The Chinese patent application number 201020659612.9 discloses an environmentally friendly electric fan, including an electric fan body, a fan blade and a driving motor are arranged in the body, a dust suction net is arranged at the air inlet or air outlet of the body, and the dust suction net is arranged in a net frame, and the net frame is connected to the body by a card or a slide. In addition, a storage slot is arranged on the bottom plate below the fan blade in the body, and the storage slot is divided into several storage compartments, and the storage slot is arranged on one side of the body in a drawer-type structure. The invention provides the user with a dust removal function by means of the dust suction net, and solves the problem of humid air by using the storage slot to be equipped with scent-absorbing cotton for distributing fragrance and water-absorbing cotton for distributing moisture.

[0004] A Chinese patent with application number 201911292003.6 discloses a cooling and heating fan, comprising: a base; a main shell, mounted on the base, the main shell being provided with a receiving cavity and an exhaust port connecting the receiving cavity with the external environment; a heating component, mounted on the base and accommodated in the receiving cavity; wherein the heating component and the exhaust port can rotate relative to each other around a rotation axis, so that the heating component and the exhaust port are opposite or staggered. The above-mentioned cooling and heating fan does not need to be provided with two exhaust ports, and because the heating component and the exhaust port can rotate relative to each other around the central axis of the base, and the outer side wall of one side of the heating component is tightly fitted to part of the inner side wall of the main shell, the circumferential space of the main shell is fully utilized, making the overall structure of the cooling and heating fan more compact and compressing the overall volume of the cooling and heating fan.

[0005] Similar to the environmentally friendly fan in the above-mentioned prior art, when adjusting the temperature of the scene, since the device is set on the ground and the air outlet and the air inlet are usually set horizontally, when the fan is working, the air flow will only flow in the lower area of ​​the scene, resulting in poor temperature regulation, dehumidification and drying effects of the fan in the scene.

[0006] Furthermore, since the air inlet and outlet of the fan in the prior art are usually connected by a single channel, when the air is dehumidified, dried and purified by the fan, the contact time between the air and the dehumidification, drying and purification components in the fan is too short, resulting in poor dehumidification, drying and air purification effects.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] First embodiment

[0040] When the temperature of the scene needs to be adjusted, since the fan is set on the ground and the air outlet 3 and the air inlet 2 are usually set horizontally, when the fan is working, the air flow will only flow in the lower area of ​​the scene, resulting in poor temperature regulation, dehumidification and drying effects of the fan in the scene. This embodiment is specially invented to solve the above problem.

[0041] Reference Figure 1 - Figure 8 An environmentally friendly fan shown includes a shell 1, and an air inlet 2 and an air outlet 3 are respectively provided on opposite sides of the shell 1, and air guide parts 4 are provided in the air inlet 2 and the air outlet 3. Two groups of air guide parts 4 are distributed up and down in the air inlet 2, and the air guide parts 4 can change the deflection angle by electric control.

[0042] An annular wind shield 11 is fixedly connected to the central area of ​​the inner cavity of the shell 1, and through holes 12 compatible with the air inlet 2 and the air outlet 3 are respectively opened at one end of the wind shield 11 close to the air inlet 2 and the air outlet 3, and baffles 13 are fixedly connected to the two ends of each through hole 12, and the end of the baffle 13 away from the wind shield 11 is fixedly connected to the side wall of the shell 1, and the baffles 13 on both sides of each through hole 12 are distributed in an "eight" shape, and the baffles 13 can gather air when entering the shell 1.

[0043] The two air guides 4 located on one side of the air inlet 2 are connected by a connecting plate 18. The air guide 4 includes an upper base plate 41, which is fixedly connected to the outer shell 1. A connecting rod 42 is provided on both sides of the upper base plate 41 along the length direction. Two sliding rods 44 are symmetrically distributed on both sides of each connecting rod 42. The connecting rod 42 and the sliding rod 44 are connected by multiple hinged rods 43, and each hinged rod 43 is provided with a fan blade 47.

[0044] A lower bottom plate 45 is disposed at one end of the connecting rod 42 away from the upper bottom plate 41 , and an electric mechanism 46 is disposed on the upper bottom plate 41 . The electric mechanism 46 can drive the sliding rod 44 to slide up and down.

[0045] A rotating part 6 is provided in the outer shell 1, and the rotating part 6 includes a wind wheel 61. The wind wheel 61 can drive air to enter the outer shell 1 from the air inlet 2 and be discharged from the air outlet 3. A base 5 is fixedly installed at the bottom of the outer shell 1. The interior of the base 5 is a hollow structure. A partition 8 is fixedly connected at the connection between the inner cavity of the base 5 and the inner cavity of the outer shell 1. A rotating motor 62 is fixedly installed in the inner cavity of the base 5. One end of the output shaft of the rotating motor 62 passes through the partition 8 and is fixedly connected to the wind wheel 61. Bearings 63 are provided at the connection between the top of the wind wheel 61 and the outer shell 1 and at the connection between the output shaft of the rotating motor 62 and the partition 8.

[0046] The wind wheel 61 includes a connecting member 611 , on which a plurality of inclined wind-fling plates 612 are arranged in a ring array. A vent 613 is provided in the middle of each connecting member 611 , and two adjacent connecting members 611 are connected via the plurality of wind-fling plates 612 .

[0047] A plurality of universal wheels 9 are arranged in a circular array around the bottom of the base 5 , each of which is provided with a locking mechanism capable of stopping the universal wheel 9 from rotating. A control panel 10 for controlling the operation of various electrical components is provided on the housing 1 .

[0048] The wind shield 11 and multiple baffles 13 divide the interior of the shell 1 into four independent chambers. The two chambers located on the side of the air outlet 3 are respectively provided with a detection chamber 15 and a dust removal chamber 16. The two chambers located on the side of the air inlet 2 are respectively provided with a purification chamber 17 and a collection chamber 14. When the wind wheel 61 rotates counterclockwise, air enters from the air inlet 2 and passes through the collection chamber 14 and the detection chamber 15 in turn and is discharged from the air outlet 3. The detection chamber 15 and the purification chamber 17 are respectively provided with a detection mechanism and a purification mechanism, and the purification mechanism can dry, dehumidify and purify the air.

[0049] An adjusting portion 7 is provided on both sides of the rotating portion 6 , respectively. The adjusting portion 7 includes a sliding member 71 and a flow guide member 72 .

[0050] When in use, the locking mechanism set on the universal wheel 9 is unlocked by controlling the locking mechanism to push the device as a whole to move. When the device moves to the designated area, for the convenience of explanation, Figure 8 Taking an example for explanation, the control panel 10 controls the rotating motor 62 to drive the wind wheel 61 to rotate counterclockwise, and the rotation of the wind wheel 61 creates wind pressure, thereby generating centrifugal wind force. As the wind wheel 61 rotates, the air on the side of the air inlet 2 is driven to flow into the outer shell 1, and driven by the wind wheel 61, the air is moved from the regulating part 7 on the right side of the wind wheel 61 toward the air outlet 3. In this process, the air entering the outer shell 1 is guided and gathered by the regulating part 7 arranged on the right side of the wind wheel 61, so that the wind force is concentrated and discharged from the air outlet 3. At the same time, the wind force generated by the rotation of the wind wheel 61 is blocked by the regulating part 7 arranged on the left side of the air outlet 3, so as to prevent part of the air from flowing back to the outer shell 1 through the left side of the wind wheel 61, thereby increasing the air output of the device, so that the device can blow out strong wind to promote the circulation of air.

[0051] When it is necessary to further improve the air circulation in the place where the device is located, the upper and lower air guides 4 located on one side of the air inlet 2 are controlled to tilt at different angles. The specific operation is: the electric mechanism 46 is controlled to drive the two sliding rods 44 located on both sides of the connecting rod 42 to slide upward and downward respectively, so that the hinged rod 43 hinged to the connecting rod 42 is tilted, driving the fan blades 47 to rotate, and the air guide 4 located above the air inlet 2 is controlled to tilt upward, and the air guide 4 located below the air inlet 2 is controlled to tilt downward, so that the upper air and the lower air in the scene where the device is located enter the outer casing 1 through the air inlet 2 at the same time and are discharged outward from the air outlet 3, so that the air in the upper, middle and lower parts of the area circulates, further improving the heat dissipation effect of the area.

[0052] Second embodiment

[0053] However, in actual use, since the air inlet 2 and the air outlet 3 of the fan in the prior art are usually connected by a single channel, when the air is dehumidified, dried and purified by the fan, the contact time between the air and the dehumidification, drying and purification components in the fan is too short, resulting in poor dehumidification, drying and air purification effects. Moreover, when the fan is used for a long time and a large amount of dust is absorbed therein, it is difficult to clean the inside of the fan. Therefore, the above-mentioned device is further improved according to the contents described in this embodiment.

[0054] The adjusting part 7 also includes a moving part 73, and one end of the moving part 73 away from the rotating part 6 is slidably connected to the inner wall of the wind shield 11. A sliding groove 74 is provided on the moving part 73, and a sliding part 71 is slidably connected in the sliding groove 74. The end of the sliding part 71 away from the rotating part 6 is fixedly connected to a telescopic part 75, and the end of the telescopic part 75 away from the sliding part 71 is fixedly connected to the sliding groove 74.

[0055] The two ends of each guide member 72 are fixedly connected to a sliding member 71 respectively, and a plurality of ventilation holes 76 are distributed in a linear array on the guide member 72. The guide member 72 can be bent and deformed and has flexibility. The sliding member 71 can drive the guide member 72 to move closer to or away from the rotating part 6 to change the flow rate of the air entering the outer shell 1 and prevent the air from flowing back in the outer shell 1.

[0056] When the device is working properly, refer to Fig. 9 As shown, driven by the wind wheel 61, the gas enters the housing 1 from the air inlet 2. At this time, the telescopic member 75 located on the left side of the wind wheel 61 is controlled to drive the two sliding members 71 to extend synchronously in the direction close to the wind wheel 61, thereby reducing the size of the opening between the wind wheel 61 and the left regulating part 7. Under the action of air pressure, the wind wheel 61 will drive the gas to flow from the right regulating part 7 to the direction of the air outlet 3. Since a plurality of air vents 76 are provided on the guide member 72, part of the gas will pass through the guide member 72 and enter the detection chamber 15. The dryness and humidity of the air and the content of harmful substances in the air are detected by the detection mechanism arranged in the detection chamber 15, while the other part of the gas moves toward the direction of the air outlet 3 through the guide of the guide member 72, so that the device can perform detection at the same time during normal air outlet.

[0057] It should be noted that the side walls of the collecting chamber 14, the detecting chamber 15, the dust removal chamber 16 and the purification chamber 17 are all provided with openings communicating with the chamber surrounded by the adjusting portion 7 and the wind shield 11, and an electric drive mechanism is provided at the connection between the wind shield 11 and the adjusting portion 7, which can control the adjusting portion 7 to slide on the wind shield 11 by electric control. By controlling the adjusting portion 7 to slide on the wind shield 11, the adjusting portion 7 can change the coverage area with different chambers according to different usage requirements.

[0058] Reference Fig.10As shown, when the detection chamber 15 detects that the content of particulate impurities and harmful substances in the air is too high, at this time, the two telescopic members 75 located on the left side of the wind wheel 61 are controlled to drive the two sliding members 71 to move in the same direction but with different strokes, so that the guide member 72 located on the left side of the wind wheel 61 moves in the direction away from the wind wheel 61, and the opening of the left guide member 72 at the air outlet 3 is larger than the opening at the air inlet 2. In this state, since the opening of the left regulating part 7 on the side of the air inlet 2 is smaller, the gas entering the housing 1 from the air inlet 2 still moves toward the direction of the air outlet 3 through the right regulating part 7 under the rotation of the wind wheel 61. As the wind wheel 61 rotates, part of the gas entering the housing 1 is discharged outward through the air outlet 3 when passing through the air outlet 3, and the other part of the gas flows toward the left regulating part 7 through the rotation of the wind wheel 61. At this time, the particulates in the air The particulate impurities will enter the dust removal chamber 16 and the purification chamber 17 through the left guide piece 72, thereby performing a first-order filtration on the impurities in the air and moving toward the right adjustment part 7 as the wind wheel 61 rotates, and performing a second-order filtration on the particulate impurities in the air through the setting of the right guide piece 72, thereby effectively separating the impurities in the particles. In the above process, when the gas moves from the left adjustment part 7 to the right adjustment part 7 through the purification component arranged in the purification chamber 17, harmful impurities in the air are sterilized by ultraviolet irradiation, thereby completing the purification of the air. At the same time, by controlling the two air guide parts 4 to respectively suck the air above and below the area into the device, and cooperating with the air outlet 3 to discharge the air, the gas in the upper, middle and lower parts of the area circulates, and all the air in the area is purified and dust-removed, further improving the purification and dust removal effect of the device.

[0059] It should be noted that the collecting chamber 14 and the detecting chamber 15 are internally connected, and the dust removal chamber 16 and the purification chamber 17 are internally connected, so that the gas can flow in the two chambers. After the guide member 72 is used for a long time, the multiple air vents 76 opened on it will gradually be blocked by dust. In this state, it is difficult for the airflow to pass through the air vents 76. Therefore, the air guiding effect of the guide member 72 on the gas will gradually increase. When it is necessary to clean the particulate impurities in the air, the guide member 72 is driven to move by the sliding member 71. Since the guide member 72 itself has a certain toughness, the dust blocking the air vents 76 will be cleaned when the guide member 72 is bent and deformed, so that the airflow can flow to different chambers through the air vents 76.

[0060] Reference Fig.11As shown, when the detection mechanism in the detection chamber 15 detects that the air is too dry or too wet, the two sliding members 71 on the left are controlled to move synchronously in the direction away from the wind wheel 61 at the same time, so that the two sliding members 71 drive the guide member 72 away from the wind wheel 61. In this state, the opening of the wind wheel 61 and the left regulating portion 7 and the connecting channel will be expanded, and at the same time, the sliding member 71 on the right side of the wind wheel 61 and close to the air outlet 3 is controlled to approach the wind wheel 61, and the sliding member 71 on the right side of the wind wheel 61 and close to the air inlet 2 is controlled to move in the direction away from the wind wheel 61, so that the opening of the guide member 72 on the right side close to the air outlet 3 becomes smaller, and the opening on the side close to the air inlet 2 becomes larger. In this state, the wind wheel 61 rotates to allow the gas to enter the housing 1 and move toward the air outlet 3 through the regulating portion 7 on the right. The opening of the side regulating part 7 close to the air outlet 3 becomes smaller, so the air flow toward the air outlet 3 becomes less. At the same time, because the opening and the connecting channel between the left regulating part 7 and the wind wheel 61 become larger, a large amount of gas will flow toward the left regulating part 7 under the rotation of the wind wheel 61. At this time, the air is dehumidified or humidified by the dehumidification or humidification component arranged in the left purification chamber 17, and the humidified or dehumidified airflow continues to flow from the side of the air inlet 2 to the right regulating part 7 driven by the wind wheel 61. Since the opening of the right regulating part 7 becomes smaller, a large amount of airflow will hover in the area of ​​the left regulating part 7 and the air inlet 2, thereby extending the humidification or dehumidification time of the airflow, effectively solving the problem in the prior art that the contact time between the air and the dehumidification, drying and purification components in the fan is too short, resulting in poor dehumidification, drying and air purification effects.

[0061] Reference Fig.12 As shown, when the detection mechanism in the detection chamber 15 detects that the air volume is less than the preset value, it means that a large amount of dust is adsorbed on the wind wheel 61 at this time, resulting in the poor driving ability of the wind wheel 61 for the airflow. In this state, by controlling the two sliding members 71 located on the right side near the air outlet 3 and the left side near the air inlet 2 to approach the wind wheel 61, and moving the other sliding member 71 away from the wind wheel 61, in this state, when the airflow entering the housing 1 flows toward the air outlet 3 through the right side adjustment portion 7, since the connecting channel of the adjustment portion 7 arranged on the right side of the wind wheel 61 gradually becomes smaller, the wind pressure gradually increases, and part of the airflow moves toward the wind wheel 61 under the action of the wind pressure, and the dust adsorbed on the wind wheel 61 is cleaned. At the same time, when the airflow moves toward the right side adjustment portion 7 through the left side adjustment portion 7, since the connecting channel of the right side adjustment portion 7 gradually becomes smaller, part of the airflow moves toward the wind wheel 61 under the action of the wind pressure, and the dust adsorbed on the wind wheel 61 is cleaned for the second time, thereby realizing the cleaning of the wind wheel 61 without disassembling the machine.
