Description

Technical Field

[0001] The present invention relates to the technical field of air purification, in particular to a ventilator for purifying air and a purification method thereof. Background Art

[0002] Ventilators usually discharge the polluted air in the room to the outside directly or after purification, and then replenish fresh air to keep the indoor air environment in line with hygiene standards. The purpose is to ensure the removal of indoor pollutants, ensure the thermal comfort of indoor occupants, and meet the needs of indoor occupants for fresh air.

[0003] When existing devices ventilate indoor air, the air inlet of the fan is usually placed indoors, while the air outlet is placed outdoors. Due to the humid indoor environment, a dehumidifier is usually added to the air inlet of the fan (the dehumidifier is filled with activated carbon to adsorb water molecules in the air) to purify (dry) the air after passing through the dehumidifier to improve the comfort of the indoor environment. However, when the air contacts the dehumidifier, it will carry a lot of dust, causing the dust to block the gaps between the activated carbons, affecting the ventilation effect. Although the dehumidifier composed of activated carbon can be cleaned from time to time, the existing cleaning methods, whether it is an external cleaning structure or manual cleaning, increase the complexity of the structure and have the following defects: At present, it is not convenient to directly clean the dust out of the ventilator, which causes the dust to float in the ventilator again, causing secondary blockage of the activated carbon. In addition, when cleaning, the fan blades of the ventilator need to stop rotating before cleaning, which affects the normal operation of the ventilator and is not conducive to indoor ventilation. In view of this, we propose a ventilator for purifying air and a purification method thereof. Summary of the invention

[0020] The following will be combined with the accompanying drawings in 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.

[0021] Building ventilation refers to the direct or purified discharge of polluted indoor air to the outside of a building, and the addition of fresh air to keep the indoor air environment in compliance with hygiene standards. Its purpose is to ensure the removal of indoor pollutants, ensure the thermal comfort of indoor occupants, and meet the needs of indoor occupants for fresh air. Figure 1-8 As shown, one of the purposes of the present invention is to provide a ventilator for purifying air, comprising a guide shell 15 and a ventilation fan 14, wherein the guide shell 15 is provided with an adjustment structure 2 for adjusting different air inlet heights of the ventilation fan 14, and the guide shell 15 is provided with a purification structure 3 for adsorbing dust and moisture in the air on one side thereof close to the ventilation fan 14; The regulating structure 2 stands opposite to the ventilation fan 14. When the ventilation fan 14 is started, the wind force sucked in passes through the regulating structure 2. When the front regulating structure 2 is used, the tilt range of the regulating structure 2 changes from a horizontal state to a tilted state, so that the regulating structure 2 changes in the direction of approaching or moving away from the ventilation fan 14, changes the speed at which the ventilation fan 14 sucks air, and makes the purification structure 3 and the ventilation fan 14 close to each other; When the ventilation fan 14 rotates, the regulating structure 2 is tilted, and the purification structure 3 cleans the adsorbed moisture and dust by adjusting the tilting amplitude of the regulating structure 2.

[0022] The present invention takes into account that when the existing device ventilates the indoor air, the air inlet end of the fan is usually placed indoors, and the air outlet end is placed outdoors. However, when the fan is used indoors, due to excessive moisture, the air entering the air inlet end of the fan should be dehumidified in time to avoid the moisture in the air being blown into the air at the air outlet end, causing pollution to the environment. The present invention cooperates with the spring 31 and the swing blade 27 and other structures. The spring 31 is arranged on the side of the ventilation fan 14 close to the swing blade 27. When the ventilation fan 14 draws air, the air is dehumidified through the dehumidification hole opened by the spring 31, and the air without impurities is discharged through the air outlet of the guide shell 15. When the ventilation fan 14 rotates, the worker adjusts the rotating sleeve 21 at the same time, so that the gap formed between the plurality of swing blades 27 changes. The ventilation fan 14 is arranged on the side away from the fixed column 24. When the ventilation fan 14 draws air, the air is drawn into the guide shell 15 through the gap between the plurality of fixed columns 24. The speed of the ventilation fan 14 drawing air can be changed by adjusting the swing blade 27. In the above embodiments, the following specific structures need to be disclosed in detail: In order to absorb and discharge air, a rotating shaft 13 is fixedly connected at the center of the ventilation fan 14, and the rotating shaft 13 is rotatably connected to the guide shell 15. The rotating shaft 13 is fixedly connected to the end away from the ventilation fan 14 with a pulley 12, and the outside of the pulley 12 is connected to the output shaft end of the motor 11 through a belt drive. A mounting block 1 is provided at the bottom of the motor 11, and the mounting block 1 is detachably connected to the guide shell 15; The ventilation fan 14 is located inside the guide housing 15; A plurality of fixing holes are provided on the side of the guide shell 15 away from the ventilation fan 14; The blades of the ventilation fan 14 are arranged at a twisted angle away from the center of the rotating shaft 13; The air inlet end of the guide shell 15 is opened at an end away from the rotating shaft 13 , and the air outlet end of the guide shell 15 is located above and away from the mounting block 1 .

[0023] When the device is in operation, the ventilation fan 14 draws air through the air inlet end of the guide shell 15. Due to the negative pressure generated by the rotation of the ventilation fan 14, the air is sucked into the guide shell 15. After the air is accelerated by the ventilation fan 14, the pressure is reduced and the kinetic energy is increased, and the air is discharged from the air outlet end of the guide shell 15.

[0024] In order to adjust the air suction speed, the adjustment structure 2 includes a rotating sleeve 21 rotatably connected to the guide shell 15, and a fixed block 22 is fixedly connected to the outer wall of the rotating sleeve 21. A pin is fitted inside the fixed block 22, and the pin is fitted with several groups of fixing holes on the side of the guide shell 15 away from the ventilation fan 14.

[0025] refer to Figure 1Before starting the motor 11, the worker pulls out the pin connected to the fixing block 22, and then pushes the fixing block 22 clockwise or counterclockwise. When the fixing block 22 drives the rotating sleeve 21 to rotate until it is in contact with the fixing hole opened on the surface of the guide shell 15, the pin is then fitted with the fixing hole opened through the fixing block 22 and the surface of the guide shell 15.

[0026] The inner wall of the rotating sleeve 21 is rotatably connected to a fixed sleeve 23, and the fixed sleeve 23 is fixedly connected to the guide shell 15 on the side close to the ventilation fan 14. The inner wall of the rotating sleeve 21 is fixedly connected to a plurality of fixed columns 24, and the plurality of fixed columns 24 are evenly distributed along the center of the rotating sleeve 21. A plurality of connecting blocks 25 are arranged between the rotating sleeve 21 and the fixed sleeve 23, and a rectangular groove is opened on the side of the plurality of connecting blocks 25 away from the rotating sleeve 21, and the fixed columns 24 are respectively connected to the rectangular grooves opened in the connecting blocks 25 in a fitting manner, and a rotating column 26 is fixedly connected to the upper inner part of the plurality of connecting blocks 25 away from the fixed columns 24, and a magnetic column 2601 is magnetically connected to one end of the plurality of rotating columns 26 away from the rotating sleeve 21, and the rotating column 26 and the magnetic column 2601 are respectively slidably connected to the outer side wall and the inner side wall of the fixed sleeve 23, and an elastic column 2602 is fixedly connected to the outer side wall of the magnetic column 2601, and a swinging blade 27 is fixedly connected to the end of the elastic column 2602 away from the rotating column 26, and a fixed disk 28 is slidably connected to the end of the magnetic column 2601 away from the swinging blade 27.

[0027] The elastic column 2602 is made of elastic material. Under the action of the elastic column 2602, a gap is generated between the magnetic column 2601 and the swing blade 27. The end of the elastic column 2602 away from the rotating column 26 is fixedly connected to the fixed disk 28. The fixed disk 28 is fixedly connected with a fixed column inside. The end of the fixed column away from the fixed disk 28 is rotatably connected to the ventilation fan 14.

[0028] refer to Figure 5 and Figure 6 As shown, when the rotating sleeve 21 rotates clockwise or counterclockwise, it drives the fixed column 24 to rotate a certain angle. When the fixed column 24 rotates, it squeezes the inner wall of the rectangular groove and drives the connecting block 25 to swing around the rotating column 26 at the same angle as the rotating sleeve 21. Because the connecting block 25 is fixedly connected to the rotating column 26, the connecting block 25 drives the rotating column 26 to rotate when it swings. The rotating column 26 rotates and drives the magnetic column 2601 magnetically connected to it to rotate. When the magnetic column 2601 rotates, it drives the swinging blade 27 to swing clockwise or counterclockwise through the elastic column 2602. Specifically, refer to Figure 1As shown, when the swing blade 27 swings clockwise or counterclockwise, the swing blade 27 will swing from left to right or from right to left around the magnetic column 2601 in sequence. At this time, the wind force generated by the ventilation fan 14 after starting will absorb the dust and moisture on the surface of the swing blade 27 close to the ventilation fan 14 through the wind force, so as to prevent the swing blade 27 from being stuck to the dust and moisture in the air on the side away from the ventilation fan 14. In summary, by the workers rotating the rotating sleeve 21 at different angles, the plurality of swing blades 27 will swing to an angle of relative rotation with the rotating sleeve 21 through the cooperation between the above-mentioned parts. At this time, the gaps formed between the plurality of swing blades 27 will change, and the workers can adjust the swing blades 27 to change the speed of air suction when the ventilation fan 14 rotates.

[0029] In order to dehumidify the air sucked by the ventilation fan 14, the purification structure 3 includes a spring 31 fixedly connected to the side of the swing blade 27 close to the ventilation fan 14, and a dehumidification sheet 32 ​​is fixedly connected to the side of the spring 31 away from the swing blade 27, and the dehumidification sheet 32 ​​is slidably connected to the guide shell 15; The dehumidifying sheet 32 ​​is connected to the fixed column inside the fixed plate 28 by sliding connection; The dehumidifying sheet 32 ​​is located between the swing blades 27 and the ventilation fan 14 .

[0030] Activated carbon is arranged inside the dehumidification sheet 32 ​​, and dehumidification holes are opened on the surface of the dehumidification sheet 32 ​​, and the cross section of the dehumidification hole close to the swing blade 27 is larger than the cross section close to the ventilation fan 14 .

[0031] refer to Figure 6 After the ventilation fan 14 is started, the outside air is discharged into the environment through the air outlet end through the air inlet end of the guide shell 15. At this time, the swing blade 27 swings around the magnetic column 2601. When the dust and moisture on the surface of the magnetic column 2601 are adsorbed by the wind force generated by the ventilation fan 14, because the dehumidification sheet 32 ​​is between the ventilation fan 14 and the swing blade 27, the dust and moisture in the air will be dehumidified by the dehumidification hole on the side of the spring 31 close to the swing blade 27 through the dehumidification sheet 32, so as to prevent dust and moisture from floating inside the guide shell 15 and causing dust and moisture in the air discharged from the air outlet of the guide shell 15. At the same time, the moisture in the environment is dehumidified by the activated carbon arranged inside the dehumidification sheet 32; refer to Figure 6 , Figure 7 and Figure 8By opening the dehumidification hole, the larger cross section is close to the side of the swing blade 27, providing a smooth transition for the air to enter the guide shell 15, reducing the turbulence of the air flow and the generation of vortex, allowing the air to enter the dehumidification hole more smoothly, and improving the working efficiency of the ventilation fan 14. The larger cross section also reduces the speed of the air entering the dehumidification hole, preventing the dust in the air and the moisture in the environment from directly passing through the dehumidification sheet 32 ​​due to high-speed movement. In addition, because the activated carbon has an adsorption function, when the ventilation fan 14 absorbs wind, the activated carbon adsorbs the moisture, preventing the moisture from entering the ventilation fan 14. At the same time, the air flow rate gradually decreases and the pressure gradually increases in the process from the large cross section to the small cross section. The increase in pressure helps to generate stronger wind force at the air outlet end of the guide shell 15, thereby improving the ventilation effect.

[0032] In order to collect the dust accumulated on the surface of the dehumidification sheet 32, the outer ring surface of the rotating sleeve 21 close to the mounting block 1 is fixedly connected with a collecting box 2101, and the collecting box 2101 is rotatably connected to the guide shell 15. The side of the collecting box 2101 away from the guide shell 15 is an inclined surface, and the side of the collecting box 2101 away from the guide shell 15 is provided with a discharge groove, and the side of the guide shell 15 away from the ventilation fan 14 is provided with a discharge groove at the same height as the discharge groove; The collecting box 2101 is located at the bottom of the dehumidification sheet 32, and the collecting box 2101 and the dehumidification sheet 32 ​​are rotatably connected.

[0033] refer to Figure 7 and Figure 8 When the ventilation fan 14 absorbs the wind force from the external environment, due to the setting of the dehumidification hole and the change of air flow, according to the Bernoulli principle, the flow velocity at the dehumidification hole increases, resulting in an increase in the force near the dehumidification hole. At this time, the pressure on the side of the dehumidification hole away from the ventilation fan 14 will be relatively reduced relative to the pressure on the side close to the swing blade 27, thereby generating a pressure difference. At this time, the swing blade 27 will squeeze the elastic column 2602 with the pressure difference and swing to the side close to the ventilation fan 14; As the ventilation fan 14 continues to absorb air from the external environment, the dehumidification holes dehumidify the dust in the air on the surface of the dehumidification holes on the side of the dehumidification sheet 32 ​​away from the ventilation fan 14. The ventilation fan 14 runs for a long time, and the dust accumulated on the surface of the dehumidification holes gradually increases, resulting in a decrease in the amount of air passing through the dehumidification holes, so that the wind force generated by the ventilation fan 14 is reduced; At this time, since the elastic column 2602 is made of elastic material, when the wind force decreases, that is, the air flow weakens, the elastic column 2602 will use its elastic characteristics to elastically drive the swing blade 27 to swing around the magnetic column 2601 to the side away from the ventilation fan 14.

[0034] In order to clean the interior of the collection box 2101 and the dust, two springs 31 are symmetrically arranged along the center line of the swing blade 27. The side of the dehumidification sheet 32 ​​close to the collection box 2101 is rotatably connected to a connecting plate 33 through a connecting shaft, and the side of the connecting plate 33 away from the dehumidification sheet 32 ​​is fixedly connected to a movable plate 34, and the movable plate 34 is inside the collection box 2101.

[0035] In summary, when the swing blade 27 moves toward the side close to the ventilation fan 14, since the two springs 31 are fixedly connected to both sides of the center line of the swing blade 27, the dehumidification sheet 32 ​​close to the connecting block 25 will be squeezed toward the side close to the ventilation fan 14 by the swing blade 27, and the dehumidification sheet 32 ​​away from the connecting block 25 will be stretched toward the side close to the ventilation fan 14 by the swing blade 27; When the swing blade 27 swings toward the side close to the ventilation fan 14, it will squeeze the spring 31, and the spring 31 will squeeze the dehumidification sheet 32 ​​at this time, so that the dehumidification sheet 32 ​​slides inside the guide shell 15 toward the side close to the ventilation fan 14. When the dehumidification sheet 32 ​​slides, it drives the movable plate 34 to slide inside the collection box 2101 toward the side close to the ventilation fan 14 through the connecting plate 33. When the connecting plate 33 slides toward the side close to the ventilation fan 14, the connecting plate 33 will swing in the direction away from the collection box 2101 along the shape of the inside of the collection box 2101. After the movement is completed, the connecting plate 33 will be in an inclined shape; refer to Figure 7 When too much dust accumulates on the surface of the dehumidification hole and the activated carbon disposed inside the dehumidification sheet 32 ​​absorbs too much moisture, the magnetic column 2601 releases the elastic swing blade 27 to swing away from the ventilation fan 14. At this time, the squeezed spring 31 and the stretched spring 31 will release the relative force, driving the dehumidification sheet 32 ​​to slide away from the ventilation fan 14. refer to Figure 8 When the dehumidification sheet 32 ​​slides, the dust accumulated on the surface of the dehumidification hole and the excessive moisture adsorbed by the activated carbon arranged inside the dehumidification sheet 32 ​​will fall into the inside of the rotating sleeve 21 along with the movement of the dehumidification sheet 32, and then the movable plate 34 is driven to slide toward the side away from the collection box 2101 through the connecting plate 33. When the connecting plate 33 slides, the dust collected inside the collection box 2101 is discharged from the inside of the guide shell 15 through the impurity discharge groove opened on the side of the collection box 2101 away from the guide shell 15 and the impurity discharge groove opened on the side of the guide shell 15 away from the ventilation fan 14. refer to Figure 8 When the movable plate 34 cleans the sticky dust at the bottom of the collection box 2101, because the movable plate 34 is set on the side of the connecting plate 33 away from the ventilation fan 14, the movable plate 34 will be limited by the side of the connecting plate 33 close to the ventilation fan 14 when cleaning the sticky dust, so that the movable plate 34 will not swing toward the side close to the ventilation fan 14. At the same time, through the elasticity of the spring 31, the sticky dust at the bottom of the collection box 2101 is cleaned.

[0036] One of the purposes of the present invention is to provide a purification method for a ventilator for purifying air, comprising the following steps: Step 1: Adjustment of air suction speed: When the air quality is good, workers adjust the adjustment structure 2 to change the tilt angle of the swing blade 27; Step 2: Air purification: Start the ventilation fan 14 to absorb and discharge the dehumidified air through the air inlet and outlet of the guide shell 15; Step 3: Air dehumidification: When the ventilation fan 14 rotates, the air is dehumidified through the dehumidification sheet 32; Step 4: Dust collection: When too much dust accumulates on the surface of the dehumidification sheet 32 ​​and the activated carbon disposed inside the dehumidification sheet 32 ​​absorbs too much moisture, the dehumidification sheet 32 ​​is driven to move by the characteristics of the elastic column 2602 and the spring 31; Step 5: Dust cleaning: The connecting plate 33 and the movable plate 34 clean the dust in the collection box 2101 out of the guide shell 15.
