Description

Technical Field

[0001] The utility model relates to the technical field of intelligent purification and cleaning, in particular to a fresh air fan with a self-cleaning air purification and dust collection device. Background Art

[0002] Fresh indoor air requires a certain amount of fresh air, so the quality of the fresh air entering the room is crucial. Processing this fresh air requires powerful air purification equipment. On the one hand, fresh air from outside is sterilized, disinfected, and filtered before being introduced indoors, ensuring fresh, clean air at all times. On the other hand, contaminated air is expelled outdoors.

[0003] Currently, air purification methods include filtration and electrostatic adsorption. Electrostatic adsorption air purification and dust collection devices utilize the principle of corona discharge to impart a positive charge to airborne particles. The collector electrode of the dust collection component is negatively charged. When positively charged particles approach the collector electrode, they are attracted to it, thereby collecting dust and reducing particulate matter in the air. However, when the dust collection reaches saturation, purification efficiency decreases, and it can also pose safety risks such as bridging, sparks, and electrical leakage.

[0004] The common dust removal method for electrostatic dust collectors is manual disassembly, cleaning, and drying before reinstallation. For electrostatic dust collectors installed within air handling units, disassembly is labor-intensive and cleaning and drying takes a long time, especially when installed on a suspended ceiling. Furthermore, electrostatic adsorption air purification and dust collection devices require extremely high voltages, and if the dust collection components are not fully dried, electrical failures can easily occur. Therefore, the development of a new air blower with a self-cleaning air purification and dust collection device is particularly important and has promising market application prospects.

[0023] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts shall fall within the scope of protection of the present invention.

[0024] Please refer to Figure 1The utility model provides a fresh air blower with a self-cleaning air purification and dust collection device, comprising an air inlet 200, a self-cleaning air purification and dust collection device 100, a dust suction and discharge component 500, a blower 600, an air outlet 300, a control and power supply device 400, and a control panel of a control quality monitoring module (not shown in the figure). The self-cleaning air purification and dust collection device 100 is connected to the dust suction and discharge component 500, and the self-cleaning air purification and dust collection device 100 is integrated with the air inlet 200, the blower 600, and the air outlet 300. The blower 600 is connected to the air outlet 300. The control and power supply device 400 controls the self-cleaning air purification and dust collection device 100, the dust suction and discharge component 500, and the blower 600 respectively. The control panel of the control quality monitoring module is equipped with a PM2.5 sensor, a CO2 sensor, and a temperature and humidity sensor. The control panel containing the control quality monitoring module can be placed externally on a desktop or embedded in a wall, and the present invention does not impose any restrictions on this.

[0025] Please refer to Figure 2 The self-cleaning air purification and dust collection device 100 includes a purification unit, a cleaning component, and a driving unit. The purification unit has a frame 10, which is a rectangular structure with an accommodating cavity formed inside; an ionization zone 12 and a dust collection zone 11 are provided in the accommodating cavity. The ionization zone 12 is composed of a ground electrode and a high-voltage ionization network. Specifically, in an embodiment of the present utility model, the high-voltage ionization network is a positive electrode made of a plurality of metal ribbons arranged in parallel at equal distances in the same plane, and each of the metal ribbons is placed between adjacent ground electrodes, and the metal ribbons are tungsten ribbons and / or molybdenum ribbons.

[0026] The dust collection area 11 includes an electrode plate with alternating positive and negative voltages as a dust collecting plate. Air is ionized in the ionization area 12, imparting positive / negative charges to airborne particles. The dust collecting plate carries a negative / positive charge, adsorbing the positive / negatively charged particles onto the dust collecting electrode. The dust collecting plate includes at least two thin plate-shaped collection assemblies, two or more of which are arranged side by side. Of course, the ionization area 12 and the dust collection area 11 may also be of other forms, and this is not a limitation of the present invention.

[0027] Please refer to Figure 2 and Figure 3The drive unit 13 includes a motor 131, a drive shaft 134, a conveyor belt 132, and two positioners 133. The motor 131 controls the drive shaft 134, which is connected to the conveyor belt 132. The two positioners 133 are located at the left and right ends of the conveyor belt 132. The dust collection area is provided with a cleaning assembly 14, which is connected to the conveyor belt 132 via a connector 15. The drive shaft 134 can drive the cleaning assembly 14 to reciprocate within the dust collection area 11 to clean the particulate matter collected and adsorbed in the dust collection area 11.

[0028] Preferably, the positioner 133 is electrically connected to the motor 131, and the positioner 133 is used to sense the position of the connector 15. The motor 131 adjusts the rotation direction of the drive shaft 134 according to the signal of the positioner 133. The positioner 133 is located on the surface of the motor 131 near the two ends of the conveyor belt 132. Specifically, the positioner 133 can be an infrared sensor or other types of sensors, and the present invention does not impose any restrictions on this. The connector 15 moves along the conveyor belt 132. When the connector 15 approaches the first positioner 1331, when the first positioner 1331 senses that the distance is less than a first threshold, the motor 131 switches the rotation direction according to the signal, causing the drive shaft 134 to reverse. Then, the cleaning component 14 will move toward the side away from the first positioner 1331 under the drive of the drive shaft 133, the conveyor belt 132 and the connector 15. When the connecting member 15 moves away from the first locator 1331 and approaches the second locator 1332, and the second locator 1332 senses that the distance between the connecting member 15 and the second locator 1332 is less than a second threshold, the motor 131 switches its rotation direction again according to the signal, causing the drive shaft 133 to reverse again. Then, the cleaning assembly 14, driven by the drive shaft 133, the conveyor belt 132, and the connecting member 15, moves toward the side closer to the first locator 1331. This reciprocating process allows the cleaning assembly 14 to automatically switch its movement direction and reciprocate to repeatedly clean the dust collection area 11.

[0029] In the embodiment of the present invention, the cleaning component 14 is a brush or scraper, preferably a brush or scraper that is wear-resistant, corrosion-resistant, high-temperature-resistant, and deformation-resistant. The cleaning component 14 is made of a highly insulating material to prevent electrical conductivity. The surface of the cleaning component 14 is dust-repellent and easily washable.

[0030] Taking the brush head as the cleaning component 14 as an example, the bristles of the brush head are located between two adjacent electrode sheets and fit tightly against the side walls of the electrode sheets. The driving unit 13 can drive the cleaning component 14 to reciprocate along the AA' direction in the dust collection area 11, thereby driving the brush to clean the particulate matter on the collection component. Specifically, the cleaning component 14 can be sleeved on the connecting member 15, and the cleaning component 14 is provided with an external thread structure, and the connecting member 15 is provided with an internal thread structure. The internal and external thread structures cooperate with each other, and the connecting member 15 is connected to the conveyor belt 132. The motor 131 drives the drive shaft 134 to rotate forward or reverse, so that the feed shaft drives the cleaning bracket to reciprocate along the axial direction of the feed shaft.

[0031] A detachable support baffle 17 is provided at the disassembly port of the frame 10, and the support baffle 17 is used to fix the ionization zone 12 and the dust collection zone 11. When the support baffle 17 is removed, the cleaning assembly 14 can be removed from the dust collection zone 11 through the disassembly port and moved out of the frame 10 to facilitate cleaning of the cleaning assembly 14; the cleaning assembly 14 after cleaning can be installed into the frame 10 through the disassembly port and connected to the connector 15. Specifically, the support baffle 17 is connected to the ends of the ionization zone 12 and the dust collection zone 11 by fastening bolts. The support baffle 17 can be removed by removing the fastening bolts, and the cleaning assembly 14 can be taken out. The operation is simple, convenient, safe and reliable.

[0032] The control and power supply device 400 mainly includes a high-voltage power supply control device of the purification unit, a circuit control device of the driving unit of the cleaning unit, a self-cleaning dust collection driving module, and a blower power supply control module.

[0033] The high-voltage power supply control device of the purification unit adopts MCU micro-control, which is achieved by adjusting the PWM pulse width according to the preset target, driving the excitation oscillation circuit, high-voltage transformer, voltage doubler rectifier circuit and different negative output terminals.

[0034] The circuit control device of the driving unit of the cleaning unit is mainly composed of a motor driving circuit, which is completed by a full-bridge SMOS brushed motor driver chip, and the forward and reverse rotation of the motor is realized through the front-end logic level.

[0035] The self-cleaning dust suction drive module is realized by controlling the PWM pulse width to control the motor speed and fan suction.

[0036] The fan power supply control module is responsible for controlling the power supply, start and stop, and wind speed of the fan.

[0037] The fresh air blower with self-cleaning air purification and dust collection device further comprises a dust discharge port, which is arranged corresponding to the dust suction and discharge component 500 and is connected to the dust suction and discharge component 500. Figure 4 The dust collection and discharge assembly 500 includes an exhaust device and a polluted air outlet. The polluted air outlet is connected to the dust outlet, and the exhaust device is disposed between the frame and the polluted air outlet. When the cleaning assembly 14 moves to the end, forming a small rectangular enclosed dust collection channel with the frame 10, the dust collection and discharge assembly 500 is activated, and the exhaust device is used to discharge dust in the dust collection channel through the dust outlet to the outside or a suitable discharge location.

[0038] Preferably, the dust suction and discharge assembly 500 is disposed at the bottom of the self-cleaning air purification dust collection device 100, outside the frame 10, and exhausts the dust swept by the cleaning assembly 14 through the exhaust device. Preferably, a dust discharge hole is provided at the connection between the frame 10 and the exhaust device to facilitate the dust suction and discharge assembly 500 to suck out the dust in the self-cleaning air purification dust collection device 100.

[0039] In combination with the above content, the working process of the fresh air fan with a self-cleaning air purification and dust collection device of the present invention is described in detail below.

[0040] A fresh air blower with a self-cleaning air purification and dust collection device. When the fresh air blower has been running for a period of time and the amount of dust collected on the dust collecting area 11 of the dust collection device reaches a certain level, the automatic cleaning program runs, the drive unit 13 starts, and the air blower 600 is stopped synchronously. The rotation of the motor 131 drives the drive shaft 134 to rotate. The drive shaft 134 is connected to the cleaning component 14 through the connector 15, so that the cleaning component 14 can reciprocate along the AA' direction; during the reciprocating movement of the cleaning component 14, the brush head (the cleaning component 14) is in close contact with the surface of the dust collecting plate in the dust collecting area 11 and rubs against each other, so that the particles adsorbed on the surface of the dust collecting plate can be effectively removed. After repeated cleaning, residual particles will adhere to the brush head, resulting in a deterioration in the cleaning effect. At this time, the support baffle 17 can be removed to remove the brush for easy cleaning. After cleaning and drying, the brush can be installed back into the frame 10 through the disassembly and assembly port, and the support baffle 17 is reset at the same time.

[0041] A new air blower with a self-cleaning air purification and dust collection device, the dust suction and discharge component 500 is composed of a DC brushless fan, a motor and a shell, and is connected to the dust discharge port. When the cleaning component 14 moves to the end and forms a smaller rectangular closed dust collection channel with the frame 10, the dust is discharged outdoors or to a suitable place for discharge under the drive of the dust suction and discharge component 500.

[0042] A control method for a fresh air blower with a self-cleaning air purification and dust collection device includes on-site control and remote control. The control and power supply device 400 includes the MCU controller, the high-voltage power supply control device of the purification unit, the circuit control device of the drive unit of the cleaning unit, the self-cleaning dust collection drive module, and the blower power supply control module. The MCU controller can start the self-cleaning device according to the set cleaning cycle; it can also receive data collected by the PM2.5 sensor, CO2 sensor, and temperature and humidity sensor built into the control panel, process the data in the MCU controller, compare and analyze the data with the set environmental level parameters, and send control instructions from the MCU controller, and make early warning prompt signals and corresponding adjustment processing instructions. The adjustment processing includes high-voltage power supply control of the purification unit, circuit control of the drive unit of the cleaning unit, self-cleaning dust collection drive control, start and stop of the blower 600, and start and stop of the clean air purification and dust collection device 100. Its operation modes are divided into the following two types:

[0043] Mode 1: Fresh air fan air supply mode

[0044] The air blower 600 is turned on, and the purification unit of the self-cleaning air purification dust collecting device 100 is operating normally. The cleaning components and driving unit of the self-cleaning air purification dust collecting device 100 are in a stopped state, and the dust suction and discharge component 500 is also in a closed state, so that the fresh air blower is in a normal air supply state in the purification mode.
