Description

Technical Field

[0001] The invention relates to the technical field of air filtration, and in particular to a self-cleaning and humidity-controlling air duct filtering device and a use method thereof. Background Art

[0002] Traditional air filtration devices usually have filter cotton inside the equipment. When the outside air passes through the filter cotton, the impurities, particles or harmful gases in it will be absorbed or blocked by the filter cotton, thereby achieving the air purification effect. The filtered air will then be discharged from the equipment for people to breathe or use.

[0003] However, the filter cotton will gradually accumulate dust and impurities during use. If it is not replaced for a long time, the filtering effect will be greatly reduced. This will not only affect the air purification quality, but also pose a potential threat to the health of users.

[0004] Therefore, users need to check and replace the filter cotton regularly, which increases the complexity of use and maintenance; on the other hand, if the filter cotton is not replaced in time, the air circulation in the equipment may be blocked, resulting in a decrease in air quality, which in turn affects the user experience. Summary of the invention

[0005] In view of the above-mentioned defects, the present invention proposes a self-cleaning and humidity-controlling air duct filter device and a method of using the same, in which the spray component and the winding component cooperate with each other to rotate the filter cotton in time, which not only avoids the long-term use of the same filter cotton, but also ensures that the filter cotton in the ventilation cavity remains moist at all times. The moist filter cotton can form a thin water film, which can absorb and retain more impurities in the air, thereby significantly improving the filtration efficiency and making the filtration effect more outstanding. Impurities on the filter cotton can also be cleaned to obtain clean and moist filter cotton, which solves the problem that traditional filtering devices require users to manually replace and clean the filter cotton.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A self-cleaning and humidity-controlling air duct filter device comprises a housing and filter cotton, wherein the housing is provided with a left partition plate and a right partition plate from left to right, and the left partition plate and the right partition plate divide the housing into a left bin, a ventilation cavity and a right bin from left to right;

[0008] The shell is provided with an air outlet at the front side of the ventilation cavity, and the shell is provided with an air inlet at the rear side of the ventilation cavity, the air inlet, the ventilation cavity and the air outlet are connected to each other, the air outlet is connected to the output end of the air supply power structure, and the air outlet is connected to the input end of the air outlet power structure;

[0009] The left bin and the right bin are both provided with a winding assembly and a spray assembly. The left end of the filter cotton is wound around the movable end of the winding assembly of the left bin, and the right end of the filter cotton passes through the left partition plate and the right partition plate in sequence, and is wound around the movable end of the winding assembly of the right bin. The two winding assemblies cooperate with each other to pull the filter cotton back and forth, and the spray assembly is used to spray the filter cotton located on the same side.

[0010] The winding assembly comprises a winding roller, a winding worm wheel, a winding worm and a driving member, wherein the winding roller is vertically rotatably mounted on the housing, the winding worm wheel is provided on the top fixed sleeve of the winding roller, the driving member is installed on the top wall of the housing, the driving end of the driving member is fixedly connected to the winding worm, and the winding worm wheel and the winding worm are meshed with each other;

[0011] The end of the filter cotton is wound around the winding roller.

[0012] The spray assembly comprises a water inlet pipe and a water distributor, the output end of the water inlet pipe is connected to the water distributor, and the spraying direction of the water distributor is horizontally toward the filter cotton.

[0013] The shell is provided with drainage slopes on the bottom walls of the left bin and the right bin, and the lowest point of the drainage slopes is flush with the input end of the first drainage pipe;

[0014] The shell is provided with a water collecting tray on the bottom wall of the ventilation cavity, and the bottom of the water collecting tray is connected to the second drain pipe.

[0015] A water supply regulating valve is provided at the input end of the water inlet pipe, and the water supply regulating valve is used to regulate the water flow in the water inlet pipe.

[0016] The shell is provided with grilles at the air inlet and the air outlet.

[0017] The left partition plate, the right partition plate and the shell are all provided with a heat-insulating layer.

[0018] It also includes a humidity sensor, an encoder and an automatic control system, wherein the humidity sensor is electrically connected to the automatic control system and is used to detect the current air humidity of the housing; the encoder is electrically connected to the automatic control system and is used to identify the number of turns of the current winding roller;

[0019] The water replenishment regulating valve is electrically connected to the automatic control system.

[0020] A method for using a self-cleaning and humidity-controlling air duct filter device comprises the following steps:

[0021] S1. The water supply regulating valves of the left and right bins are opened at the same time at the initial opening value, and water flows from the outlets of the water inlet pipes of the left and right bins to spray onto the filter cotton;

[0022] S2. The driving parts of the left and right bins are started at the same time, and the winding rollers of the left and right bins rotate in the same direction, and the wet filter cotton moves in a preset direction to completely cover the ventilation cavity;

[0024] S4. After the water supply regulating valve reaches the opening limit value for a period of time, the PID control algorithm is used to calculate and adjust the current speed of the driving parts of the left and right bins;

[0025] S5. When the encoder of one bin recognizes that the number of rotations of the current winding roller is at a certain set value, the driving parts and winding rollers of the left and right bins rotate in opposite directions, and the wet filter cotton moves in opposite directions, and the above steps S3-S4 are repeated.

[0026] The technical solution of the present invention may include the following beneficial effects:

[0027] 1. The spray assembly and the winding assembly cooperate with each other to rotate the filter cotton in time, which not only avoids the long-term use of the same filter cotton, but also ensures that the filter cotton in the ventilation cavity remains moist at all times. The moist filter cotton can form a thin layer of water film, which can absorb and retain more impurities in the air, thereby significantly improving the filtration efficiency and making the filtration effect more outstanding. It solves the problem that traditional filtration devices require users to manually replace filter cotton.

[0028] 2. The water inlet pipe is connected to the external water supply device. The water flows from the water inlet pipe to the water distributor. Then the water distributor disperses the water into small impact water streams and sprays them horizontally on the filter cotton to ensure that the water can be evenly distributed on the surface of the filter cotton, which can not only avoid the situation where the filter cotton is partially too wet or too dry.

[0029] 3. The spray components of the left and right compartments are started at the same time. One of the spray components can moisten the filter cotton to keep it moist, and the other spray component can wash away dust and other debris on the filter cotton. It not only has the effect of humidification, but also has the function of self-cleaning.

[0030] 4. This solution is also equipped with a humidity sensor and an automatic control system. The humidity sensor can accurately detect the current air humidity inside the shell. Through continuous monitoring, it can provide real-time feedback on the humidity changes in the environment, providing an accurate data basis for subsequent humidity adjustments. When the humidity sensor detects that the air humidity exceeds the predetermined range, it can immediately send a signal to the automatic control system to serve as a timely warning. This enables the system to respond quickly and adjust the opening of the water supply regulating valve to prevent the humidity from further deviating from the ideal range, thereby achieving real-time adjustment of the air humidity and achieving the effect of humidity control.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "splicing" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Combine the following Figures 1 to 3 , describing a self-cleaning and humidity-controlling air duct filtering device and a method of using the same according to an embodiment of the present invention.

[0041] A self-cleaning and humidity-controlling air duct filter device comprises a housing 1 and filter cotton 2, wherein the housing 1 is provided with a left partition plate 11 and a right partition plate 12 from left to right, and the left partition plate 11 and the right partition plate 12 divide the housing 1 from left to right into a left bin 13, a ventilation cavity 14 and a right bin 15;

[0042] The shell 1 is provided with an air outlet at the front side of the ventilation cavity 14, and the shell 1 is provided with an air inlet at the rear side of the ventilation cavity 14, the air inlet, the ventilation cavity 14 and the air outlet are connected to each other, the air outlet is connected to the output end of the air supply power structure, and the air outlet is connected to the input end of the air outlet power structure;

[0043] The left bin 13 and the right bin 15 are both provided with a winding assembly 3 and a spray assembly 4. The left end of the filter cotton 2 is wound around the movable end of the winding assembly 3 of the left bin 13. The right end of the filter cotton 2 passes through the left partition plate 11 and the right partition plate 12 in sequence and is wound around the movable end of the winding assembly 3 of the right bin 15. The two winding assemblies 3 cooperate with each other to pull the filter cotton 2 back and forth. The spray assembly 4 is used to spray the filter cotton 2 located on the same side.

[0044] The operation process is as follows: start the spray assembly 4 in the left bin 13, and ensure that the spray assembly 4 sprays water on the filter cotton 2 in the left bin 13, so that the filter cotton 2 is fully absorbed by water. Synchronously start the winding assemblies 3 at both ends, and the winding assemblies 3 work together to make the filter cotton 2 in the left bin 13 move from left to right, and then wind around the winding assembly 3 in the right bin 15. Since the spray assembly 4 sprays the filter cotton 2 all the time, the wet filter cotton 2 moves into the ventilation cavity 14. Continue to start the winding assemblies 3 at both ends, so that the wet filter cotton 2 passes through the right partition plate 12, and ensure that the filter cotton 2 in the ventilation cavity 14 is wet.

[0045] When the wet filter cotton 2 passes through the right partition plate 12 and is located in the right bin 15 , the spray assembly 4 of the right bin 15 sprays water with impact force onto the filter cotton 2 to wash away dust and other debris on the filter cotton 2 , thereby cleaning the filter cotton 2 .

[0046] When most of the filter cotton 2 is located in the right bin 15 , the winding components 3 at both ends are started to rotate in the opposite direction. At this time, the filter cotton 2 located in the right bin 15 moves from right to left and is then wound around the winding component 3 located in the left bin 13 .

[0047] Then the air supply power structure delivers the outside air to the air inlet, and the outside air passes through the air inlet, the filter cotton 2 and the air outlet in sequence, and is discharged to the outside from the air outlet power structure. It is worth noting that both the air supply power structure and the air outlet power structure are air pumps, which provide a stable and reliable power source for the flow of air, avoiding the situation where the filtering effect is reduced due to insufficient power of the outside air.

[0048] The left partition plate 11 and the right partition plate 12 are both provided with vertical through holes for the filter cotton 2 to pass through, so as to ensure that the filter cotton can pass through the ventilation cavity 12 to filter the air.

[0049] The device can effectively filter out dust, particulate matter and other impurities in the air and improve the air quality by setting the filter cotton 2 in the left compartment 13 and the right compartment 15. At the same time, the addition of the spray component 4 allows the filter cotton 2 to be humidified during the filtering process, thereby releasing more fresh and moist air, which is particularly suitable for use in a dry environment, helping to improve indoor humidity and enhance living comfort.

[0050] The spray assembly 4 and the winding assembly 3 cooperate with each other to rotate the filter cotton 2 in time, which not only avoids the long-term use of the same filter cotton 2, but also ensures that the filter cotton 2 located in the ventilation cavity 14 is always kept moist. The moist filter cotton 2 can form a thin layer of water film, which can absorb and retain more impurities in the air, thereby significantly improving the filtration efficiency and making the filtration effect more outstanding. In addition, the moist filter cotton 2 can also have a humidification effect. When dry air passes through the moist filter cotton 2, the moisture in the filter cotton 2 will gradually be released into the air, thereby increasing the humidity of the air, providing people with a more comfortable living environment, and solving the problem that the traditional filtering device requires the user to manually replace the filter cotton 2.

[0051] The winding assembly 3 includes a winding roller 31, a winding worm wheel 32, a winding worm 33 and a driving member 34. The winding roller 31 is vertically rotatably mounted on the housing 1. The winding worm wheel 32 is fixedly sleeved on the top of the winding roller 31. The driving member 34 is installed on the top wall of the housing 1. The driving end of the driving member 34 is fixedly connected to the winding worm 33. The winding worm wheel 32 and the winding worm 33 are meshed with each other.

[0052] The end of the filter cotton 2 is wound around the winding roller 31 .

[0053] It is worth noting that the driving member 34 is preferably a motor. The driving member 34 drives the winding worm 33 to rotate, and since the winding worm wheel 32 and the winding worm 33 are meshed with each other, the winding worm wheel 32 drives the winding roller 31 to rotate accurately. The winding roller 31 is precisely controlled by controlling the rotation speed and rotation frequency of the driving member 34, thereby ensuring effective cleaning and uniform use of the filter cotton 2.

[0054] In order to better protect the winding assembly 3 from the influence of water flow, two horizontal partition plates are arranged on the inner side of the housing 1, one of which is horizontally connected to the inner wall of the housing 1 and the left partition plate 11, and the other is horizontally connected to the housing 1 and the right partition plate 12. The winding worm wheel 32, the winding worm 33 and the driving member 34 are all located above the partition plate, and the end of the winding roller 31 and the filter cotton 2 are located below the partition plate.

[0055] The spray assembly 4 includes a water inlet pipe 41 and a water distributor 42 . The output end of the water inlet pipe 41 is connected to the water distributor 42 . The spraying direction of the water distributor 42 is horizontally toward the filter cotton 2 .

[0056] Among them, the water inlet pipe 41 is connected with the external water supply device, and the water flows from the water inlet pipe 41 to the water distributor 42, and then the water distributor 42 disperses the water into fine water flows with impact force, and sprays it horizontally on the filter cotton 2, ensuring that the water can be evenly distributed on the surface of the filter cotton 2, which can not only avoid the situation where the filter cotton 2 is partially over-wet or over-dry, but also can wash away dust and other debris on the filter cotton 2, thereby improving the humidification and filtering effects.

[0057] The water sprayed on the filter cotton 2 helps to absorb and fix impurities such as dust and particulate matter in the air, thereby enhancing the filtering effect of the filter cotton 2 and further improving the overall air purification capability.

[0058] The water distributor 42 sprays outward, which can not only moisten the filter cotton 2 and effectively reduce the dryness of the air in the device and the room, thereby reducing the generation of static electricity, but also wash away dust and other debris on the filter cotton 2, thereby playing the role of automatically cleaning the filter cotton 2.

[0059] The housing 1 is provided with drainage slopes 51 on the bottom walls of the left bin 13 and the right bin 15, and the lowest point of the drainage slopes 51 is flush with the input end of the first drainage pipe 52;

[0060] The housing 1 is provided with a water collecting tray 53 on the bottom wall of the ventilation cavity 14 , and the bottom of the water collecting tray 53 is connected to the second drain pipe 54 .

[0061] The drainage slope 51 and the first drainage pipe 52 respectively arranged at the bottom of the left bin 13 and the right bin 15 can ensure that the excess water generated during the spray humidification process or the water dripping from the filter cotton 2 can quickly flow to the lowest point along the drainage slope 51. Since the lowest point of the drainage slope 51 is flush with the input end of the drainage pipe, it is ensured that the water can smoothly flow into the first drainage pipe 52 without leakage or overflow. Therefore, the accumulated water on the drainage slope 51 can be smoothly discharged to the outside of the device through the first drainage pipe 52, effectively avoiding the accumulation of water inside the left bin 13 and the right bin 15, and reducing the problem of bacterial growth and corrosion caused by accumulated water.

[0062] The water collecting pan 53 disposed on the bottom wall of the ventilation chamber 14 can not only collect the water dripping from the filter cotton 2, but also collect the dust particles adhering to the water, because the wet filter cotton 2 has a good filtering effect. Moreover, the water collecting pan 53 is connected to the second drain pipe 54, so the water collecting pan 53 can discharge the sewage containing dust in time to prevent the dust from re-entering the air, thereby further improving the cleanliness of the air.

[0063] A water supply regulating valve 43 is provided at the input end of the water inlet pipe 41 , and the water supply regulating valve 43 is used to regulate the water flow in the water inlet pipe.

[0064] The water replenishment regulating valve 43 can accurately control the water flow entering the water distributor 42, thereby adjusting the wetting state of the filter cotton 2, avoiding unnecessary energy consumption caused by excessive wetting of the filter cotton 2, and thus saving water resources and energy.

[0065] The housing 1 is provided with grilles at the air inlet and the air outlet.

[0066] The grille at the air inlet can perform preliminary filtering on the air entering the device, intercepting some larger particles and impurities. When the air passes through the moist filter cotton 2, the filter load of the filter cotton 2 will be relatively reduced, and the filtration efficiency will be correspondingly improved. The grille can effectively prevent insects or other foreign objects from entering the device, thereby protecting key components such as the filter cotton 2 from damage, extending the service life of the device of this solution, and reducing failures and maintenance costs caused by the entry of foreign objects.

[0067] The left partition plate 11, the right partition plate 12 and the shell 1 are all provided with a heat-insulating layer.

[0068] The setting of the heat preservation layer effectively enhances the heat preservation performance of the device. In a cold environment, the heat preservation layer can reduce the loss of heat and keep the temperature inside the filter device stable.

[0069] In cold seasons, the insulation layer can reduce heat loss, and the spray assembly 4 that sprays warm water outward can maintain a suitable working temperature of the filter cotton 2 to prevent water from freezing on the filter cotton 2, causing the filter cotton 2 to be unable to filter the air.

[0070] It also includes a humidity sensor, an encoder and an automatic control system, wherein the humidity sensor is electrically connected to the automatic control system and is used to detect the current air humidity of the housing 1; the encoder is electrically connected to the automatic control system and is used to identify the number of turns of the current winding roller 31;

[0071] The water replenishment regulating valve 43 is electrically connected to the automatic control system.

[0072] The humidity sensor can accurately detect the current air humidity inside the housing 1. Through continuous monitoring, it can provide real-time feedback on the humidity changes in the environment, providing an accurate data basis for subsequent humidity adjustments. When the humidity sensor detects that the air humidity exceeds a predetermined range, it can immediately send a signal to the automatic control system to serve as a timely warning. This enables the system to respond quickly and adjust the opening of the water supply regulating valve 43 to prevent the humidity from further deviating from the ideal range, thereby achieving real-time adjustment of the air humidity and achieving the effect of humidity control.

[0073] A method for using a self-cleaning and humidity-controlling air duct filter device comprises the following steps:

[0074] S1, the water supply regulating valves 43 of the left and right bins 15 are opened at the same time at the initial opening value, and water flows from the outlets of the water inlet pipes 41 of the left and right bins 15 to spray onto the filter cotton 2;

[0075] S2, the driving members 34 of the left and right bins 15 are started simultaneously, the winding rollers 31 of the left and right bins 15 rotate in the same direction, and the wetted filter cotton 2 moves in a preset direction so as to completely cover the ventilation cavity 14;

[0076] S3, according to the actual value of the current air humidity detected by the humidity sensor, the PID control algorithm is used to calculate and adjust the current opening value of the water supply regulating valve 43 of the left and right compartments 15;

[0077] S4, after a period of time when the water supply regulating valve 43 reaches the opening limit value, the PID control algorithm is used to calculate and adjust the current rotation speed of the driving member 34 of the left and right bins 15;

[0078] S5. When the encoder of one bin recognizes that the number of rotations of the current winding roller 31 is at a certain set value, the driving members 34 and the winding roller 31 of the left and right bins 15 rotate in opposite directions, and the wet filter cotton 2 moves in opposite directions, and the above steps S3-S4 are repeated.

[0079] According to the current measured value of air humidity detected by the humidity sensor, the automatic control system adjusts the opening value of the water supply regulating valve 43 and the rotation speed of the driving member 34, thereby realizing accurate control of the air humidity in the air duct. This is of great significance for some places that are sensitive to humidity, such as museums, libraries, archives, etc. Appropriate air humidity can protect precious cultural relics, books, archives, etc. from damage by moisture or dryness, and extend their preservation life.

[0080] The entire air filter device realizes intelligent control, and can automatically clean the filter cotton 2 and control the air humidity without manual intervention. This greatly reduces the workload and difficulty of manual operation and improves management efficiency. For example, in some large ventilation systems, traditional maintenance methods may require a lot of manpower and time to replace the filter cotton 2 and adjust the humidity. However, this self-cleaning and humidity-controlling air duct filter device can monitor and adjust in real time through an automated control system to ensure that the ventilation system is always in the best condition, saving labor costs and management costs.

[0081] At the same time, intelligent control methods can also improve the reliability and stability of the system and reduce the risks caused by human operational errors.

[0082] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
