Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, and in particular to a self-cleaning method and an air conditioner. Background Technology
[0002] With the rapid development of the logistics industry, drivers often live in their vehicles to save on transportation costs. To meet drivers' strong demands for a comfortable in-vehicle environment, parking air conditioners are usually installed on the roof, in the cab, or in the middle of the cargo compartment to adjust the interior environment. Therefore, the cooling effect and energy efficiency of parking air conditioners are particularly important.
[0003] The applicant has discovered that the prior art has at least the following technical problems:
[0004] Trucks that typically use parking air conditioners operate in complex and varied environments, especially in harsh dusty environments such as sandstorm areas and coal mining areas in Northwest China. In such scenarios, dust particles in the air can be drawn into the air conditioner, causing the copper pipes of the indoor and outdoor units to crack and the heat exchanger fins to accumulate dust, thus affecting the cooling or heating performance. Summary of the Invention
[0005] The purpose of this invention is to provide a self-cleaning method, device, storage medium, electronic device, and air conditioner to solve the technical problem of poor cooling or heating effect of air conditioners in harsh environments in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] In a first aspect, the present invention provides a self-cleaning method for self-cleaning a parking air conditioner, the method comprising:
[0008] Preset baseline dust concentration threshold E0;
[0009] Obtain environmental dust concentration parameters;
[0010] The acquired environmental dust concentration parameters are compared with the preset baseline dust concentration threshold E0, and subsequent processing steps are performed based on the comparison results.
[0011] The self-cleaning method provided by this invention can control the air conditioner in real time according to environmental conditions, thereby improving the cooling or heating effect of the air conditioner in harsh environments.
[0012] Furthermore, the acquisition of environmental dust concentration parameters includes:
[0013] The environmental dust concentration was extracted several times according to a set time interval t.
[0014] The environmental dust concentration parameters are obtained by averaging the several environmental dust concentration measurements.
[0015] To avoid misjudgments and ensure accurate air conditioning notifications based on environmental parameters, the environmental dust concentration parameters obtained in this invention are not instantaneous parameters, but average values over a period of time. By acquiring environmental dust concentrations multiple times over a period of time and then averaging them, precise control of the air conditioning can be achieved.
[0016] Furthermore, based on the comparison results, the subsequent processing steps include:
[0017] When the ambient dust concentration parameter is less than or equal to the baseline dust concentration threshold E0, the air conditioner is controlled to operate normally.
[0018] When the baseline dust concentration threshold E0 is less than the ambient dust concentration parameter and less than 3.5 times the baseline dust concentration threshold E0, the air conditioner will start its self-cleaning mode.
[0019] When the ambient dust concentration parameter is ≥ 3.5 times the baseline dust concentration threshold E0, the air conditioner is turned off and dust prevention measures are initiated.
[0020] By judging the average environmental dust concentration over a period of time and comparing it with a preset threshold, when the threshold is exceeded, it indicates that the environment has deteriorated and air conditioning needs to be controlled. In order to avoid over-control and over-self-cleaning, which would lead to excessive energy consumption, different processing steps need to be executed according to the severity of the environmental degradation. This not only improves the intelligent control of air conditioning, but also achieves the goal of energy saving and consumption reduction.
[0021] Furthermore, the control of the air conditioner to activate the self-cleaning mode includes:
[0022] When the baseline dust concentration threshold E0 < the ambient dust concentration parameter ≤ 1.5 times the baseline dust concentration threshold E0, the air conditioner is controlled to start the first self-cleaning mode.
[0023] When 1.5 times the baseline dust concentration threshold E0 is less than the ambient dust concentration parameter and 2.5 times the baseline dust concentration threshold E0, the air conditioner is controlled to start the second self-cleaning mode.
[0024] When the ambient dust concentration parameter is less than 3.5 times the baseline dust concentration threshold E0, the air conditioner is controlled to start the third self-cleaning mode.
[0025] By dividing harsh environmental conditions into three ranges, when the actual environmental dust concentration parameter falls into a certain range, the air conditioner will perform self-cleaning according to the self-cleaning mode corresponding to that range.
[0026] Furthermore, the control of the air conditioner to activate the first self-cleaning mode includes:
[0027] The dustproof screen rotating disc rotates 90 degrees at a rotation speed V1, rotating the air inlet dustproof screen from the air inlet to the heating module. The heating module is controlled to heat and dry the air inlet dustproof screen at a heating power H1.
[0028] After the heat treatment is completed, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V1, rotating the air inlet dustproof screen to the dust collection module. The dust collection module is controlled at a dust collection intensity of X1 to remove the heated and dried dust located on the air inlet dustproof screen.
[0029] After vacuuming is complete, the dust filter rotating disc rotates 90 degrees at a rotation speed of V1, rotating the air inlet dust filter to the scraping module. The scraping module is controlled at a scraping speed of G1 to physically remove the dirt that has not been removed from the air inlet dust filter.
[0030] After scraping is complete, the dustproof screen rotating disc rotates 90 degrees at a rotation speed V1, rotating the dustproof screen at the air inlet to the air inlet position.
[0031] Furthermore, the control of the air conditioner to activate the second self-cleaning mode includes:
[0032] The dustproof screen rotating disc rotates 90 degrees at a rotation speed of V2, rotating the air inlet dustproof screen from the air inlet to the heating module. The heating module is controlled to heat and dry the air inlet dustproof screen at a heating power of H2.
[0033] After the heat treatment is completed, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V2, rotating the air inlet dustproof screen to the dust collection module. The dust collection module is controlled at a dust collection intensity of X2 to remove the heated and dried dust located on the air inlet dustproof screen.
[0034] After vacuuming is complete, the dust filter rotating disc rotates 90 degrees at a rotation speed of V2, rotating the air inlet dust filter to the scraping module. The scraping module is controlled at a scraping speed of G2 to physically remove the dirt that has not been removed from the air inlet dust filter.
[0035] After scraping is complete, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V2, rotating the dustproof screen at the air inlet to the air inlet position.
[0036] Furthermore, the control of the air conditioner to activate the third self-cleaning mode includes:
[0037] The dustproof screen rotating disc rotates 90 degrees at a rotation speed of V3, rotating the air inlet dustproof screen from the air inlet to the heating module. The heating module is controlled to heat and dry the air inlet dustproof screen at a heating power of H3.
[0038] After the heat treatment is completed, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V3, rotating the air inlet dustproof screen to the dust collection module. The dust collection module is controlled at a dust collection intensity of X3 to remove the heated and dried dust located on the air inlet dustproof screen.
[0039] After vacuuming is complete, the dust filter rotating disc rotates 90 degrees at a rotation speed of V3, rotating the air inlet dust filter to the scraping module. The scraping module is controlled at a scraping speed of G3 to physically remove the dirt that has not been removed from the air inlet dust filter.
[0040] After scraping is complete, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V3, rotating the dustproof screen at the air inlet to the air inlet position.
[0041] Furthermore, before controlling the air conditioner to operate normally, the following steps are also included:
[0042] Get the time since the last cleaning of the air conditioner;
[0043] When the interval time is greater than the set period N, the air conditioner is controlled to start the first self-cleaning mode;
[0044] When the time interval obtained is less than or equal to the set period N, the air conditioner is controlled to operate normally.
[0045] Furthermore, in the three self-cleaning modes, the heating power is H1 < H2 < H3, the suction strength is X1 < X2 < X3, the rotation speed is G1 < G2 < G3, and the rotation speed is V3 < V2 < V1.
[0046] In the three self-cleaning modes, as the dust concentration increases, the heating power of the corresponding heating module H1 < H2 < H3. The higher the heating power, the better the heating effect on the dust filter and the faster the heating speed, especially for dust and particulate matter with increased humidity, as humidity is a significant factor affecting the viscosity of dust and the surface of the dust filter. As the dust concentration increases, the suction intensity of the corresponding suction module X1 < X2 < X3. The higher the suction intensity, the better the dust removal effect on the dust filter, and its working principle is similar to that of a vacuum cleaner. As the dust concentration increases, the rotation speed of the corresponding physical scraping module G1 < G2 < G3. The faster the rotation speed, the better the dust removal effect on the dust filter. As the dust concentration increases, the rotation speed of the dust filter rotating disc module V3 < V2 < V1. The slower the rotation speed, the longer the dust filter stays on each module, resulting in a better dust removal effect.
[0047] Furthermore, the dustproof treatment includes: rotating the dustproof housing to cover the dustproof mesh at the air inlet, preventing airborne dust from entering the air conditioner and the driver's cab.
[0048] In a second aspect, the present invention provides an air conditioner for performing the method; the air conditioner includes:
[0049] The air intake dustproof component is installed at the air intake to prevent dust from entering the air conditioner during operation.
[0050] A self-cleaning system is installed at the location of the air intake dustproof component, which is used to automatically clean the air intake dustproof component when environmental parameters exceed the standard.
[0051] An environmental monitoring module is connected to the self-cleaning system to provide environmental dust concentration parameters to the self-cleaning system.
[0052] Furthermore, the air intake dustproof component includes:
[0053] The dustproof base has a grooved structure.
[0054] An air inlet is located inside the dustproof base to allow airflow.
[0055] The dustproof mesh module is rotatably installed inside the dustproof base, ensuring that it always covers the top of the air inlet during rotation.
[0056] The dustproof housing is a cover-shaped structure, which is rotatably installed inside the dustproof base and located on top of the dustproof mesh module. The dustproof housing has through holes that are compatible with the specifications of the air inlet.
[0057] Furthermore, the dustproof net module includes:
[0058] The dust filter rotating disc has a cross-shaped structure, and its center is rotated and mounted on the air conditioner body via a drive component;
[0059] There are four dustproof nets at the air inlet, which are respectively arranged at the four free ends of the dustproof net rotating disk.
[0060] Furthermore, the self-cleaning system is arranged at the bottom of the dustproof net module and is located within the rotation coverage area of the dustproof net module, enabling it to automatically clean the dustproof net module when it rotates to the position of the self-cleaning system.
[0061] Furthermore, the self-cleaning system includes a heating module, a dust extraction module, and a scraping module arranged in a semi-circle next to the air inlet.
[0062] Furthermore, the air conditioner mentioned is a parking air conditioner.
[0063] Furthermore, the heating module includes a resistance wire.
[0064] Furthermore, the vacuuming module includes a high-powered suction motor.
[0065] Furthermore, the scraping module includes a flexible silicone plate or a brush.
[0066] The parking air conditioner provided by this invention monitors the concentration of particulate matter in the external environment in real time by setting an environmental monitoring module. Based on different dust and particulate matter concentrations, it determines whether to activate the self-cleaning mode. By setting a self-cleaning system, it can determine the environment in which the parking air conditioner is located and select the corresponding autonomous cleaning mode according to different environments. By setting heating, dust suction, and scraping modules, different cleaning processes can be achieved. Different autonomous cleaning modes have different heating rates, dust suction intensity, and physical scraping speeds, achieving more precise cleaning. Attached Figure Description

[0072] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0073] like Figure 1 As shown, this invention provides a self-cleaning method for self-cleaning a parking air conditioner, the method comprising:
[0074] S1, Preset baseline dust concentration threshold E0;
[0075] S2. Obtain environmental dust concentration parameters through the environmental monitoring module; In this embodiment, the parking air conditioner needs to be equipped with an environmental monitoring module, which can measure the dust concentration in the air to cope with harsh operating environments, such as mines, deserts, and Gobi areas.
[0076] It should be noted here that obtaining environmental dust concentration parameters includes:
[0077] The environmental dust concentration was extracted several times according to a set time interval t.
[0078] The environmental dust concentration parameters are obtained by averaging the several environmental dust concentration measurements.
[0079] To avoid misjudgments and ensure accurate air conditioning notifications based on environmental parameters, the environmental dust concentration parameters obtained in this invention are not instantaneous parameters, but average values over a period of time. By acquiring environmental dust concentrations multiple times over a period of time and then averaging them, precise control of the air conditioning can be achieved.
[0080] Furthermore, the time interval t can be five minutes or other time intervals, without specific limitations. The number of environmental parameters obtained can be four or other times, without limitations.
[0081] The following explanation uses a five-minute time interval and four repetitions as an example:
[0082] In this embodiment, the environmental data acquired by the environmental monitoring module is not instantaneous data, but rather the average value is obtained by averaging four data points within twenty minutes after extracting test data every five minutes, thereby obtaining the environmental dust concentration parameter.
[0083] S3. Compare the acquired environmental dust concentration parameters with the preset baseline dust concentration threshold E0. Based on the comparison results, execute subsequent processing steps. In other words, the parking air conditioner will activate different air conditioning operation modes according to the different dust concentrations in the air.
[0084] The self-cleaning method provided by this invention can control the air conditioner in real time according to environmental conditions, thereby improving the cooling or heating effect of the air conditioner in harsh environments.
[0085] Furthermore, based on the comparison results, subsequent processing steps are performed, including:
[0086] S31. When the ambient dust concentration parameter is ≤ the baseline dust concentration threshold E0, the air conditioner is controlled to operate normally. Specifically, this means that the dust concentration in the air is relatively low and the outside air quality is good. At this time, the parking air conditioner is turned on normally and there is no need to turn on the self-cleaning mode.
[0087] To ensure timely cleaning and optimal operation of the air conditioner, after the above judgments are completed and it is determined that the cleaning mode does not need to be activated, it is also necessary to determine the interval since the last cleaning to further determine whether the self-cleaning mode needs to be activated. Specifically, before controlling the air conditioner to operate normally, the following steps are also included:
[0088] Get the time since the last cleaning of the air conditioner;
[0089] When the interval time is greater than the set period N, the air conditioner is controlled to start the first self-cleaning mode; this indicates that the air conditioner has been running for a long time or has been idle for a period of time, and the first self-cleaning mode needs to be activated for cleaning.
[0090] When the time interval is less than or equal to the set period N, the air conditioner will operate normally without needing to activate the self-cleaning mode.
[0091] S32. When the reference dust concentration threshold E0 is less than the ambient dust concentration parameter and less than 3.5 times the reference dust concentration threshold E0, the air conditioner is controlled to start the self-cleaning mode. This indicates that the dust concentration in the air is relatively high and the outside air quality is poor. However, the parking air conditioner can be turned on normally at this time, and the self-cleaning mode needs to be turned on.
[0092] Furthermore, controlling the air conditioner to activate its self-cleaning mode includes:
[0093] When the baseline dust concentration threshold E0 < the ambient dust concentration parameter ≤ 1.5 times the baseline dust concentration threshold E0, the air conditioner is controlled to start the first self-cleaning mode.
[0094] Furthermore, controlling the air conditioner to activate the first self-cleaning mode includes:
[0095] The dustproof screen rotating disc rotates 90 degrees at a rotation speed V1, rotating the air inlet dustproof screen from the air inlet to the heating module. The heating module is controlled to heat and dry the air inlet dustproof screen at a heating power H1.
[0096] After the heat treatment is completed, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V1, rotating the air inlet dustproof screen to the dust collection module. The dust collection module is controlled at a dust collection intensity of X1 to remove the heated and dried dust on the air inlet dustproof screen into the storage box.
[0097] After vacuuming is complete, the dust filter rotating disc rotates 90 degrees at a rotation speed of V1, rotating the air inlet dust filter to the scraping module. The scraping module is controlled to use a flexible brush to physically remove stubborn dirt that has not been removed from the air inlet dust filter at a scraping speed of G1.
[0098] After scraping is complete, the dustproof screen rotating disc rotates 90 degrees at a rotation speed V1, rotating the dustproof screen at the air inlet to the air inlet position.
[0099] When 1.5 times the baseline dust concentration threshold E0 is less than the ambient dust concentration parameter and 2.5 times the baseline dust concentration threshold E0, the air conditioner is controlled to start the second self-cleaning mode.
[0100] Furthermore, control the air conditioner to activate the second self-cleaning mode, including:
[0101] The dustproof screen rotating disc rotates 90 degrees at a rotation speed of V2, rotating the air inlet dustproof screen from the air inlet to the heating module. The heating module is controlled to heat and dry the air inlet dustproof screen at a heating power of H2.
[0102] After the heat treatment is completed, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V2, rotating the air inlet dustproof screen to the dust collection module. The dust collection module is controlled at a dust collection intensity of X2 to remove the heated and dried dust on the air inlet dustproof screen into the storage box.
[0103] After vacuuming is complete, the dust filter rotating disc rotates 90 degrees at a rotation speed of V2, rotating the air inlet dust filter to the scraping module. The scraping module is controlled to use a flexible brush to physically remove stubborn dirt that has not been removed from the air inlet dust filter at a scraping speed of G2.
[0104] After scraping is complete, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V2, rotating the dustproof screen at the air inlet to the air inlet position.
[0105] When the ambient dust concentration parameter is less than 3.5 times the baseline dust concentration threshold E0, the air conditioner is controlled to start the third self-cleaning mode.
[0106] Furthermore, control the air conditioner to activate the third self-cleaning mode, including:
[0107] The dustproof screen rotating disc rotates 90 degrees at a rotation speed of V3, rotating the air inlet dustproof screen from the air inlet to the heating module. The heating module is controlled to heat and dry the air inlet dustproof screen at a heating power of H3.
[0108] After the heat treatment is completed, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V3, rotating the air inlet dustproof screen to the dust collection module. The dust collection module is controlled at a dust collection intensity of X3 to remove the heated and dried dust on the air inlet dustproof screen into the storage box.
[0109] After vacuuming is complete, the dust filter rotating disc rotates 90 degrees at a rotation speed of V3, rotating the air inlet dust filter to the scraping module. The scraping module is controlled to use a flexible brush at a scraping speed of G3 to physically remove stubborn dirt that has not been removed from the air inlet dust filter.
[0110] After scraping is complete, the dustproof screen rotating disc rotates 90 degrees at a rotation speed of V3, rotating the dustproof screen at the air inlet to the air inlet position.
[0111] By dividing harsh environmental conditions into three ranges, when the actual environmental dust concentration parameter falls into a certain range, the air conditioner will perform self-cleaning according to the self-cleaning mode corresponding to that range.
[0112] In this invention, the air inlet dustproof net needs to enter four positions: the air inlet position, the heating module position, the dust suction module position, and the scraping module position. Therefore, in this invention, there are four air inlet dustproof nets, which are arranged at 90-degree intervals. During the operation of the dustproof net rotating disk, there is an air inlet dustproof net at each position, so as to ensure that when the first air inlet dustproof net is being cleaned, there is always an air inlet dustproof net above the air inlet.
[0113] Furthermore, in the three self-cleaning modes, the heating power is H1 < H2 < H3, the suction strength is X1 < X2 < X3, the rotation speed is G1 < G2 < G3, and the rotation speed is V3 < V2 < V1.
[0114] In the three self-cleaning modes, as the dust concentration increases, the heating power of the corresponding heating module H1 < H2 < H3. The higher the heating power, the better the heating effect on the dust filter and the faster the heating speed, especially for dust and particulate matter with increased humidity, as humidity is a significant factor affecting the viscosity of dust and the surface of the dust filter. As the dust concentration increases, the suction intensity of the corresponding suction module X1 < X2 < X3. The higher the suction intensity, the better the dust removal effect on the dust filter, and its working principle is similar to that of a vacuum cleaner. As the dust concentration increases, the rotation speed of the corresponding physical scraping module G1 < G2 < G3. The faster the rotation speed, the better the dust removal effect on the dust filter. As the dust concentration increases, the rotation speed of the dust filter rotating disc module V3 < V2 < V1. The slower the rotation speed, the longer the dust filter stays on each module, resulting in a better dust removal effect.
[0115] S33. When the ambient dust concentration parameter is ≥ 3.5 times the baseline dust concentration threshold E0, the air conditioner is turned off and dust prevention is activated. This indicates that the dust concentration in the air is very high and the outside air quality is very poor. At this time, the parking air conditioner is turned off, and the dustproof shell of the air conditioner rotates at a certain angle to cover the dustproof net of the air inlet, preventing air dust from entering the air conditioner and the driver's cab.
[0116] This invention determines the average environmental dust concentration over a period of time and compares it with a preset threshold. When the threshold is exceeded, it indicates that the environment has deteriorated and air conditioning needs to be controlled. To avoid over-control and excessive self-cleaning, which would lead to excessive energy consumption, different processing steps are executed according to the severity of the environmental degradation. This not only improves the intelligent control of air conditioning but also achieves the goal of energy saving and consumption reduction.
[0117] Furthermore, dust prevention measures are initiated, including rotating the dustproof housing to cover the dust filter at the air inlet, preventing airborne dust from entering the air conditioning system and the driver's cab.
[0118] like Figure 2 and Figure 3 As shown, the present invention provides an air conditioner for performing the above-described self-cleaning method; this air conditioner is a parking air conditioner, comprising:
[0119] The air intake dustproof component is installed at the air intake 1 to prevent dust from entering the air during air conditioner operation;
[0120] The self-cleaning system is installed at the air intake dustproof component and is used to automatically clean the air intake dustproof component when environmental parameters exceed the standard.
[0121] An environmental monitoring module connects to the self-cleaning system to provide environmental dust concentration parameters to the system.
[0122] The parking air conditioner provided by this invention monitors the concentration of particulate matter in the external environment in real time by setting an environmental monitoring module. Based on different dust and particulate matter concentrations, it determines whether to activate the self-cleaning mode. By setting a self-cleaning system, it can determine the environment in which the parking air conditioner is located and select the corresponding autonomous cleaning mode according to different environments. By setting heating, dust suction, and scraping modules, different cleaning processes can be achieved. Different autonomous cleaning modes have different heating rates, dust suction intensity, and physical scraping speeds, achieving more precise cleaning.
[0123] Furthermore, such as Figure 3 As shown, the air intake dustproof assembly includes:
[0124] Dustproof base 2 has a circular groove structure;
[0125] Air inlet 1 is a circular hole located inside the dustproof base 2, used for airflow; specifically, as... Figure 2 and Figure 3 As shown, the circular space of the base 2 can be divided into four areas by a 90-degree dividing line, namely the first area, the second area, the third area and the fourth area. The air inlet 1 is located in the first area of the base 2.
[0126] The dustproof mesh module is rotatably installed inside the dustproof base 2, and can always cover the top of the air inlet 1 during rotation. With this structure, the dustproof mesh module that is initially located at the air inlet 1 will still be in the air inlet 1 for dust prevention when it rotates to the self-cleaning system position when cleaning is required.
[0127] The dustproof housing 3 is a cover-shaped structure, rotatably mounted inside the dustproof base 2, and located on top of the dustproof mesh module. The dustproof housing 3 has through holes that match the specifications of the air inlet 1. During normal air conditioner use, the dustproof housing 3 covers the top of the dustproof mesh module. Since the dustproof housing 3 has only one through hole and the rest is a closed structure, the through hole on the dustproof housing 3 is aligned with the air inlet 1 to ensure airflow. At this time, the self-cleaning system located in other areas of the dustproof housing 3, being isolated from the external environment, can prevent or reduce dust from entering the self-cleaning system. When the environment deteriorates too much and the air conditioner needs to be shut down, the dustproof housing 3 is rotated so that its through hole is misaligned with the air inlet 1.
[0128] Furthermore, the dustproof mesh module includes:
[0129] The dust filter rotating disk 4 has a cross-shaped structure, and its center is rotated on the air conditioner body 100 through a drive component. Specifically, the drive component can be a servo motor, or other existing drive components, as long as they can drive the dust filter rotating disk 4 to rotate.
[0130] The air inlet dustproof net 5 is circular, and there are four of them, which are respectively arranged at the four free ends of the dustproof net rotating disk 4.
[0131] Furthermore, the self-cleaning system is located at the bottom of the dustproof net module and within the rotation coverage area of the dustproof net module, enabling it to automatically clean the dustproof net module when it rotates to the position of the self-cleaning system. In this embodiment, as... Figure 3 As shown, the self-cleaning system includes a heating module 6, a dust extraction module 7, and a scraping module 8 arranged in a semi-circle next to the air inlet 1.
[0132] The heating module includes a resistance wire or other heating element for heating the dust filter 5 at the air inlet, which rotates above it, and the heating power H is adjustable. The suction module 6 includes a high-powered suction motor or other element capable of providing suction force, and the suction intensity X is adjustable. The scraping module 7 is a physical scraping module, including a flexible silicone plate or brush, and the scraping speed G is adjustable. The driving component can be a servo motor or other components that can drive the rotation of parts, and its rotation speed V is adjustable.
[0133] In this embodiment, the dustproof mesh rotating disk 4 can rotate relative to the dustproof base 2 through the driving component, thereby enabling different air inlet dustproof meshes 5 to face the air inlet 1 or the self-cleaning system.
[0134] Of course, the dustproof mesh module may not need to use such a method. Figure 2 and Figure 3 Alternatively, a circular dustproof mesh rotating disk 4 can be used. A cross-shaped frame is set inside the inner ring of the circular dustproof mesh rotating disk 4 so that the dustproof mesh rotating disk 4 can be rotatably fixed in the dustproof base 2. An air inlet dustproof mesh 5 is set around the entire circle between the inner and outer rings of the circular ring. This ensures that the air inlet 1 is always covered by the air inlet dustproof mesh 5. However, this structure will result in a large amount of air inlet dustproof mesh 5 used, which will increase the cost.
[0135] In this embodiment, the dustproof housing 3 can rotate relative to the dustproof mesh rotating disk 4 and the dustproof base 2. The drive component for rotation and the drive component for controlling the rotation of the dustproof mesh rotating disk 4 are two independent components. For ease of installation, a motor can be installed on the upper edge of the dustproof base 2, with a gear on the motor output shaft, and a gear on the side of the dustproof housing 3. When the gears mesh, the motor can drive the dustproof housing 3 to rotate.
[0136] To prevent dust from entering the self-cleaning system during use, a dustproof component, such as a brush or soft rubber, should be installed between the self-cleaning system and the dustproof rotating disc 4, but no specific limitations are specified here.
