[0002] Currently, parking air conditioners are typically installed on the roof of passenger cars or trucks to regulate the interior environment. In various driving environments, the condenser's air inlet and outlet are located on the outside of the truck. The condenser usually uses air cooling for heat dissipation. Over extended periods, dust and other impurities accumulate in the condenser, clogging it and significantly reducing its ventilation and heat dissipation efficiency, leading to a noticeable increase in the air conditioning unit's power consumption. To ensure proper heat dissipation, the condenser needs frequent cleaning. However, frequent cleaning is labor-intensive, and the roof installation requires climbing to disassemble and clean it, greatly increasing the safety risks involved. Utility Model Content

[0046] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

The singular forms “a,” “said,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0048] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0049] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0050] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0051] like Figure 1As shown, an exemplary embodiment of this utility model provides a condenser dustproof device 200, which is applied to a parking air conditioner 100 in a vehicle. The parking air conditioner 100 can be installed in a vehicle for use by occupants. Vehicles may include, but are not limited to, logistics vehicles, trucks, and RVs.

[0052] The parking air conditioner 100 can be an electrically driven air conditioner installed in the driver's cab of the vehicle. This parking air conditioner 100 does not require engine starting and does not need a separate engine. It can be powered and continuously operated by the vehicle's DC power supply. The air outlet of the parking air conditioner 100 is connected to the vehicle's interior to regulate the temperature inside the vehicle through the cool air generated, thereby improving the driver's driving experience.

[0053] The parking air conditioner 100 may include, but is not limited to, roof-mounted parking air conditioners and built-in parking air conditioners. The parking air conditioner 100 may include a power supply unit and a power generation unit. The power supply unit is used to supply power to the parking air conditioner 100 to ensure its operation. The power supply unit may include a battery, which may include, but is not limited to, lead-acid batteries, lithium batteries, graphene batteries, etc.

[0054] The power generation unit is used to supplement the power supply unit's power. That is, when the power generation unit is operating, the electricity it generates can charge the power supply unit, thereby supplementing its power. The power generation unit may include, but is not limited to, generators, or it may include a solar power generation device, such as photovoltaic solar panels. The generator or solar power generation device is configured to charge the power supply unit.

[0055] The parking air conditioner 100 includes a chassis 110 and a condenser 111, with the condenser 111 mounted on the chassis 110. The chassis 110 can be fixed to the vehicle and provides a stable support structure for the condenser 111, ensuring that the condenser 111 will not shift or shake during operation. Additionally, the chassis 110 can also serve as a stable working platform, facilitating maintenance and repair work by repair personnel.

[0056] In addition, the chassis 110 can also provide a certain degree of protection for the condenser 111 during operation, preventing it from being affected by the external environment, such as preventing some dust, moisture, mud and sand from entering the interior of the condenser 111.

[0057] Meanwhile, the chassis 110 also provides some heat insulation, reducing the impact of external heat on the condenser 111 and ensuring that the condenser 111 operates within a suitable temperature range. On the other hand, the chassis 110 can also provide a stable support structure for other structures or components in the parking air conditioner 100. With the corresponding reasonable structural design on the chassis 110, airflow can be guided evenly across the surface of the condenser 111, improving heat dissipation efficiency.

[0058] like Figures 1 to 3 As shown, the dustproof device 200 includes: a dustproof net 210, a transmission assembly 220, and a dust removal assembly 230.

[0059] Dustproof nets 210 are arranged around the upper and lower sides of the condenser 111, forming a dustproof ring with a receiving space for the condenser 111. This dustproof ring can be used to filter impurities in the air passing through or facing the condenser 111. The dustproof net 210 has a windward side facing the windward side of the condenser 111, a leeward side facing the leeward side of the condenser 111, and dustproof net end faces located at both ends of the condenser 111 and connected to the windward and leeward sides of the dustproof net.

[0060] It should be noted that the dust seal is used to filter impurities in the air passing through the condenser 111. When the condenser 111 is in operation, impurities in the air passing through the condenser 111 will be intercepted by the dust seal.

[0061] The dustproof ring is used to filter impurities in the air facing the condenser 111. When the condenser 111 is not in operation, impurities in the air passing through the condenser 111 will be intercepted by the dustproof ring under the influence of external factors such as wind.

[0062] For example, the dust filter 210 can prevent dust, bacteria, pollen, and other fine particulate matter in the air flowing through the condenser 111 from entering the interior of the condenser 111. This not only avoids dust accumulation and bacterial growth but also reduces the risk of mechanical failure and blockage inside the condenser 111. In addition, the dust filter 210 can reduce the frequency of cleaning and maintenance costs of the condenser 111 and the parking air conditioner 100, thus reducing adverse environmental impacts.

[0063] The dustproof net 210 can be made of high-density mesh fabric or metal wire mesh, so as to improve the service life of the dustproof net 210 while achieving the dustproof function of the condenser 111.

[0064] The transmission assembly 220 can be mounted on the chassis 110 of the parking air conditioner. The transmission assembly 220 can be used to drive the dust cover ring to rotate. The chassis 110 can provide a stable mounting base for the transmission assembly 220. The transmission assembly 220 includes a drive component 224 and a transmission component 223 driven by the drive component. The transmission component 223 supports the dust cover net 210 to form a receiving space while driving the dust cover ring.

[0065] The chassis 110 typically possesses sufficient strength and rigidity to withstand various forces generated by the transmission components 220 during operation, such as torque and vibration.

[0066] The chassis 110 is the basic structural part of the entire parking air conditioner 100. The placement of the transmission assembly 220 on the chassis 110 helps to optimize the overall layout of the parking air conditioner 100. It can make the center of gravity distribution of the various components of the parking air conditioner 100 more reasonable, reducing the equipment shaking or instability that may be caused by the center of gravity shift.

[0067] The rotation of the dustproof ring helps achieve a uniform dustproof effect. If the dustproof ring remains stationary, dust may gradually accumulate in a fixed direction, forming a local dust accumulation area, which may eventually break through the protection of the dustproof ring. However, when the dustproof ring rotates, it can come into contact with the external environment in all directions in turn, evenly dispersing the dust that may enter the condenser 111 on the circumference of the dustproof ring, avoiding excessive accumulation in some areas, thereby improving the overall dustproof capability.

[0068] By rotating the dust seal, the risk of damage to a fixed part due to long-term exposure to dust, wear, and other factors can be reduced. For example, during the operation of condenser 111, if the dust seal is stationary, the rubber or other materials in that part may wear prematurely due to the impact of dust and sand particles blown from a certain direction. Rotation, however, can distribute the wear evenly across the entire dust seal, extending its service life and protecting the precision components inside the equipment from dust corrosion, thus reducing the maintenance and replacement costs of the equipment.

[0069] In some embodiments, the transmission component 220 can control the rotation of the dustproof ring through gear transmission, belt transmission or chain transmission, etc.

[0070] The dust removal component 230 can also be installed on the chassis 110 of the parking air conditioner. The dust removal component 230 is arranged opposite to the dust filter 210. That is, along the rotation direction of the dust filter ring, the dust removal component 230 is installed at both ends of the dust filter ring so as to filter the impurities on the dust filter 210 during the rotation of the dust filter ring driven by the transmission component 220.

[0071] Mounting the dust removal component 230 on the chassis 110 helps optimize the layout of all parts of the parking air conditioner 100. From the perspective of the overall functional flow of the equipment, there is a collaborative working relationship between the various components on the chassis 110. Mounting the dust removal component 230 on the chassis 110 facilitates a reasonable spatial arrangement with other related components, enabling efficient use of space within the parking air conditioner 100. It also facilitates the assembly, maintenance, and repair of the various components of the parking air conditioner 100.

[0072] The dust collection components 230, positioned at both ends of the dustproof ring along its rotation direction, ensure comprehensive removal of collected impurities. As the dustproof ring rotates, dust, debris, and other impurities are collected from all directions. Regardless of where the impurities rotate with the dustproof ring, the dust collection components 230 at both ends ensure timely removal. These components guarantee that impurities are processed at both the beginning and end of the dustproof ring, preventing their accumulation and circulation on the ring.

[0073] This configuration fully utilizes the rotational characteristics of the dustproof ring. The rotation of the dustproof ring gradually transports impurities to both ends, and the dust removal components 230 are located precisely at these critical points, making the impurity removal process more efficient. Compared to installing the dust removal components 230 at only one location, having them at both ends covers more situations. For example, if the dust removal component is only installed at one end, if the dustproof ring, due to some reason (such as wind direction, equipment vibration, etc.), causes more impurities to accumulate at the other end, impurity removal may be delayed. Having components at both ends avoids this situation.

[0074] In this example, the dustproof device 200 can effectively collect impurities in the air passing through the condenser 111, reducing the accumulation of impurities in the condenser 111. At the same time, the transmission component 220 drives the dustproof net 210 to rotate, so that the dust removal component 230 can quickly remove the accumulated impurities, keeping the dustproof net 210 in a clean state, thereby ensuring and improving the ventilation and heat dissipation effect of the condenser 111.

[0075] like Figures 1 to 3 As shown, in some embodiments, the transmission assembly 220 includes a main drive shaft 221, a driven shaft 222, a transmission element 223, and a drive element 224.

[0076] Along the direction of rotation of the dustproof ring, the main drive shaft 221 and the driven drive shaft 222 are respectively inserted into the dustproof ring. This design allows the dustproof ring to rotate in conjunction with the driven drive shaft 222 when the main drive shaft 221 rotates.

[0077] In addition, through the through-hole structural design, the dustproof ring can play a good dustproof role for the main drive shaft 221 and the driven drive shaft 222, ensuring that the main drive shaft 221 and the driven drive shaft 222 work in a relatively clean environment, reducing the potential for failure caused by impurities, and reducing unnecessary vibration and offset, thus ensuring the overall stability of the transmission assembly 220.

[0078] The transmission component 223 is fixedly connected to the annular side of the dustproof ring, and its two ends in opposite directions are respectively connected to the main drive shaft 221 and the driven drive shaft 222, so that the main drive shaft 221 and the driven drive shaft 222 can rotate together. The transmission component 223 can take various forms, such as a belt, chain, or coupling, to effectively transmit the power from the main drive shaft 2231 to the driven drive shaft 222.

[0079] The output end of the drive component 224 is connected to the main drive shaft 221. The drive component 224 can be a motor, generator, or other equipment. As the starting point for the operation of the entire transmission assembly 220, when the drive component 224 drives the main drive shaft 221 to rotate, the rotational motion of the main drive shaft 221 is transmitted to the driven shaft 222 through the transmission component 223, thereby realizing the rotation of the entire dustproof ring. In this way, the rotation of the dustproof ring helps to achieve a uniform dustproof effect, so that it comes into contact with the external environment in all directions in turn, and evenly disperses the dust that may enter the condenser 111 on the circumference of the dustproof ring, avoiding excessive local accumulation, thereby improving the overall dustproof capability.

[0080] like Figures 1 to 3 As shown, in some embodiments, a main drive shaft 221 is provided with a main drive wheel 225, and a driven drive shaft 222 is provided with a driven drive wheel 226.

[0081] The transmission component 223 is sleeved on the main transmission wheel 225 and the driven transmission wheel 226, so as to drive the main transmission shaft 221 and the driven transmission shaft 222 to rotate in coordination through the transmission component 223.

[0082] As the main component for power transmission, the main drive shaft 221 is equipped with a main drive wheel 225, which transforms the rotation of the main drive shaft 221 into a form more suitable for receiving by the transmission component 223. When the main drive shaft 221 rotates, the main drive wheel 225 rotates accordingly. Due to the connection of the transmission component 223, this rotation drives the driven wheel 226 to rotate, thereby causing the driven shaft 222 to rotate. Moreover, the transmission component 223 ensures that the main drive shaft 221 and the driven shaft 222 rotate according to a predetermined transmission ratio, thereby ensuring the stable and efficient operation of the entire transmission assembly 220.

[0083] like Figures 1 to 3 As shown, in some embodiments, the number of transmission components 223 is two.

[0084] In a mechanical transmission system, having two transmission components 223 provides redundancy. If one transmission component 223 fails, such as a broken chain (assuming the transmission component is a chain) or an excessively worn belt (assuming the transmission component is a belt), the other transmission component 223 can still maintain power transmission between the main drive shaft 221 and the driven shaft 222. This redundancy design improves the operational stability of the entire transmission assembly 220 and reduces the risk of the entire transmission assembly 220 stopping due to the failure of a single transmission component 223.

[0085] Furthermore, the two transmission components 223 can better distribute the force during power transmission. When the main drive shaft 221 transmits power to the driven shaft 222, the two transmission components 223 share the torque and tension forces. For example, when transmitting a large torque, the two transmission components 223 can evenly distribute the load, reducing the stress on each transmission component 223 and thus extending the service life of the transmission components 223.

[0086] Along the direction of rotation perpendicular to the dustproof ring, the two transmission components 223 are respectively arranged on the two annular sides of the dustproof ring. This arrangement is rational in terms of space utilization. In this way, the space on both sides of the dustproof ring can be fully utilized, and mutual interference between the transmission components 223 can be avoided.

[0087] From a dustproofing perspective, the arrangement of the two transmission components 223 on both sides of the dustproof ring helps to better protect the main drive shaft 221 and the driven drive shaft 222 inside the dustproof ring. Because the transmission components 223 are located on both sides of the dustproof ring, dust, impurities, etc. generated during transmission are less likely to enter the interior of the dustproof ring.

[0088] For example, when the transmission component 223 vibrates or experiences airflow disturbance during operation, this arrangement can prevent external dust from being drawn into the dustproof ring, thereby ensuring that the dustproof ring can effectively perform its function of blocking dust and protecting the main drive shaft 221 and the driven drive shaft 233 in a relatively clean environment.

[0089] like Figures 1 to 3 As shown, in some embodiments, the transmission element 223 is a transmission belt, and the main transmission wheel 225 and the driven transmission wheel 226 are pulleys.

[0090] When the transmission component 223 is a transmission belt, it can bring the characteristics of flexible connection to the entire transmission assembly 220. Compared with rigid connection transmission methods (such as direct gear meshing), the transmission belt can better adapt to the slight misalignment that may exist between the main drive pulley 225 and the driven drive pulley 226. That is to say, the transmission belt can compensate for this misalignment through its own elastic deformation, and can still effectively transmit power to ensure the coordinated rotation between the main drive shaft 221 and the driven drive shaft 222.

[0091] The transmission belt also functions as a buffer and shock absorber. During power transmission, especially when the output of the drive component 224 experiences impact or vibration, the transmission belt can absorb this energy. For example, when the drive component 224 suddenly starts or stops, the transmission belt can use its elasticity to buffer this sudden change in force, reducing the impact on the main drive pulley 225, the driven pulley 226, the main drive shaft 221, and the driven shaft 222. Based on this, it helps protect all components in the entire transmission assembly 220, extends its service life, and reduces the noise and vibration levels of the transmission assembly 220 during operation.

[0092] The transmission belt is fitted onto the main drive pulley 225 and the driven pulley 226, transmitting power through the friction between them. When the main drive shaft 221 drives the main pulley to rotate, the main pulley, through friction with the transmission belt, causes the transmission belt to begin moving. Since the transmission belt is also fitted onto the driven pulley, it in turn drives the driven pulley to rotate, thereby realizing the rotation of the driven drive shaft 222.

[0093] like Figures 1 to 3 As shown, in some embodiments, the drive component 224 includes a drive motor. A drive motor is a device that converts electrical energy into mechanical energy. It generates rotational torque through the principle of electromagnetic induction, thereby driving the movement of other components.

[0094] The drive motor can be a DC motor, an AC asynchronous motor, a permanent magnet synchronous motor, or a switched reluctance motor, etc. Drive motors offer advantages such as high efficiency, precise control, high reliability, and are energy-saving and environmentally friendly.

[0095] like Figures 1 to 3 As shown, in some embodiments, the dust removal component 230 is disposed opposite to and abuts against at least one end face of the dustproof net 210. That is, the dust removal component 230 can be disposed on one side of the dustproof net 210 to effectively remove impurities filtered on the dustproof net 210. Alternatively, the dust removal component 230 can be disposed on both sides of the dustproof net 210 and perform multiple effective filtrations on the impurities filtered on the dustproof net 210 to improve filtration efficiency and ensure that the dustproof net 210 is kept clean.

[0096] Alternatively, the dust removal assembly 230 may include a first dust removal unit 231 and a second dust removal unit 232.

[0097] Along the rotation direction of the dustproof ring, the first dust removal unit 231 and the second dust removal unit 232 are located on both sides of the dustproof ring and respectively abut against the surface of the dustproof ring. The first dust removal unit 231 is positioned close to the drive member 224. When the dustproof ring rotates, the first dust removal unit 231 and the second dust removal unit 232 are used to remove impurities collected on the dustproof ring.

[0098] The first dust removal unit 231 and the second dust removal unit 232 work together to remove impurities from the dustproof ring. The first dust removal unit 231 can adopt a brush structure to brush away dust and other impurities by contacting the surface of the dustproof ring with the brush. The second dust removal unit 232 can adopt a suction structure to further suck up the remaining microparticles after the brush cleaning, thereby achieving a more thorough cleaning effect.

[0099] Along the rotation direction of the dustproof ring, the first dust removal unit 231 and the second dust removal unit 232 are located on both sides of the dustproof ring and abut against its surface. Therefore, when the dustproof ring rotates, each part of its surface can be cleaned sequentially by the two dust removal units, ensuring the dustproof ring is in a clean environment and achieving a high degree of cleanliness. This sequential cleaning method using two dust removal units effectively removes various impurities collected during operation, ensuring the dustproof ring's dustproof function remains continuously and effectively performed. This protects critical components such as the drive shaft from impurities and maintains the stable operation of the entire transmission assembly 220 and the condenser 111.

[0100] like Figures 1 to 3 As shown, in some embodiments, the end face of the dustproof mesh is an arc-shaped surface. Along the rotation direction of the dustproof ring, the two ends of the dustproof ring are defined as a first arc-shaped surface and a second arc-shaped surface. The two arc-shaped rotating surfaces can evenly distribute the stress of the dustproof ring during rotation, which helps the dustproof ring rotate more smoothly and also ensures the stability of the entire dustproof ring during the cleaning process.

[0101] The first dust removal unit 231 includes a first bracket 23a and a first brush 23b mounted on the first bracket 23a. The first bracket 23a is mounted on the chassis 110 and serves to support and fix the first brush 23b, providing a stable mounting platform for the first brush 23b. The first bracket 23a can be made of metal to ensure that the first dust removal unit 231 will not deform during operation due to its strength and rigidity.

[0102] Specifically, a first arc-shaped mounting position is provided on the first bracket 23a, and a first brush 23b is disposed on the first arc-shaped mounting position so that the first brush 23b abuts against the first arc-shaped surface. This arc-shaped mounting position matches the arc-shaped rotating surface of the dustproof ring, which can ensure that the first brush 23b maintains a good contact state during the rotation of the dustproof ring, thereby effectively brushing away the dust, impurities and other substances adsorbed on the surface of the dustproof ring during the rotation, and playing a good cleaning role.

[0103] The second dust removal unit 232 includes a second bracket 23c and a second brush 23d mounted on the second bracket 23c. The second bracket 23c is mounted on the chassis 110 and serves to support and fix the second brush 23d, providing a stable mounting platform for the second brush 23d. The second bracket 23c can be made of metal to ensure that the second dust removal unit 232 will not deform during operation due to its strength and rigidity.

[0104] Specifically, a second arc-shaped mounting position is provided on the second bracket 23c, and the second brush 23d is positioned on the second arc-shaped mounting position so that the second brush 23d abuts against the second arc-shaped surface. This arc-shaped mounting position matches the arc-shaped rotating surface of the dustproof ring, ensuring that the second brush 23d maintains good contact during the rotation of the dustproof ring, thereby effectively brushing away dust, impurities, etc. adsorbed on the surface of the dustproof ring during rotation, achieving a good cleaning effect.

[0105] In this example, the structure of two brushes and two supports is used so that the first dust removal unit 231 and the second dust removal unit 232 can achieve comprehensive cleaning of both ends of the dustproof ring by contacting the corresponding arc-shaped rotating surface of the dustproof ring with their respective brushes. This ensures the cleanliness of the dustproof ring, better performs its dustproof function, and protects the performance and ventilation performance of the condenser 111.

[0106] like Figure 4 and Figure 5 As shown, an exemplary embodiment of this utility model also provides a parking air conditioner 100, which can be installed in a vehicle for use by the occupants of the vehicle. The vehicle may include, but is not limited to, logistics vehicles, trucks, RVs, etc.

[0107] The parking air conditioner 100 can be an electrically driven air conditioner installed in the driver's cab of the vehicle. This parking air conditioner 100 does not require engine starting and does not need a separate engine. It can be powered and continuously operated by the vehicle's DC power supply. The air outlet of the parking air conditioner 100 is connected to the vehicle's interior to regulate the temperature inside the vehicle through the cool air generated, thereby improving the driver's driving experience.

[0108] The parking air conditioner 100 may include, but is not limited to, roof-mounted parking air conditioners and built-in parking air conditioners. The parking air conditioner 100 may include a power supply unit and a power generation unit. The power supply unit is used to supply power to the parking air conditioner 100 to ensure its operation. The power supply unit may include a battery, which may include, but is not limited to, lead-acid batteries, lithium batteries, graphene batteries, etc.

[0109] The power generation unit is used to supplement the power supply unit's power. That is, when the power generation unit is operating, the electricity it generates can charge the power supply unit, thereby supplementing its power. The power generation unit may include, but is not limited to, generators, or it may include a solar power generation device, such as photovoltaic solar panels. The generator or solar power generation device is configured to charge the power supply unit.

[0110] The parking air conditioner 100 includes a chassis 110, a condenser 111, and a dustproof device 200 in any of the above embodiments.

[0111] In addition, the parking air conditioner 100 also includes other structures, such as the outer cover 112, the external fan 113, the deflector 114, the evaporating foam 115, the internal fan 116, the evaporator 117, the internal unit panel 118, the compressor 119, the electrical box components 120, and other structural components, system connection pipes, and control devices.

[0112] All other structures mentioned above are mounted on the chassis 110. The condenser 111 is fixed to the rear half of the chassis 110. The chassis 110 has three ventilation openings: one for an external fan, one for an internal fan, and one for an internal fan outlet. The indoor unit panel 118 is mounted below the chassis 110. The internal fan 116, evaporator 117, and evaporative foam 115 are mounted above the chassis 110 and the indoor unit panel 118. The indoor unit panel 118, evaporator 117, and evaporative foam 115 form an air circulation channel.

[0113] When the parking air conditioner is working, the airflow enters from the indoor unit panel 118 through the indoor unit panel air inlet, then passes through the air inlet on the chassis 110, flows through the evaporator 117, the air exchanges heat with the evaporator 117, and then the airflow is blown out by the indoor fan 116 through the air outlet grille on the indoor unit panel 118.

[0114] Furthermore, the air inlet of the outdoor fan on the chassis 110 is located below the condenser 111, and a guide shroud 114 is installed above the condenser 111. The guide shroud 114 has a hole, and the outdoor fan 113 is installed in the hole on the guide shroud 114. The outer cover 112 has a corresponding air outlet at the air outlet of the outdoor fan 113. The air inlet of the outdoor fan on the chassis 110, the condenser 111, the guide shroud 114, and the air outlet of the outer cover 112 form an air circulation channel.

[0115] When the parking air conditioner is working, the outside air flows sequentially through the air inlet of the external fan on the chassis 110, the condenser 111, the deflector 114, the external fan 113, and the air outlet on the outer cover 112 before being discharged to the outside. When the airflow passes through the condenser 111, the dust filter 210 under the condenser 111 filters the air passing through it, causing dust to accumulate in the dust filter 210. Then, the drive motor drives the dust filter 210 to rotate, causing it to be cleaned in real time by the first brush 23b and the second brush 23d. The dust generated falls into the chassis 110.

[0116] When the parking air conditioner 100 is not working, outside dust will fall onto the condenser 111 through the air outlet on the outer cover 112, the outside fan 113, and the deflector 114. At this time, the dust will accumulate in the dust filter 210 above the condenser 111.

[0117] When the parking air conditioner 100 restarts, the drive motor starts, and the dust filter 210 rotates synchronously. Under the sweeping action of the first brush 23b and the second brush 23d, the dust accumulated above the dust filter 210 falls onto the chassis 110. In this way, dust entering the parking air conditioner 100 from both the external fan inlet and the external hood outlet of the chassis 110 is intercepted and filtered by the dust filter 2101 surrounding the condenser 111, effectively preventing dust accumulation in the condenser 111 and ensuring its heat dissipation. Simultaneously, driven by the drive motor, the dust filter 210 remains clean, ensuring its ventilation effect. Two brushes are placed on the front and rear sides of the dustproof net 210 in the direction of rotation to prevent dust from falling back into the dustproof net 210. Dust that falls into the chassis 110 will be flushed out through the drain hole (not shown in the figure) to the outside of the parking air conditioner 100 by condensation or rainwater.

[0118] Based on this, in this example, the dustproof device 200 can effectively prevent dust from entering the condenser 111 and can also automatically clean the dustproof net 210.

[0119] An exemplary embodiment of the present invention also provides a vehicle that includes the parking air conditioner 100 described above.

[0120] In this example, the dustproof device 200 can effectively collect impurities in the air passing through the condenser 111, reducing the accumulation of impurities in the condenser 111. At the same time, the transmission component 220 drives the dustproof net 210 to rotate, so that the dust removal component 230 can quickly remove the accumulated impurities, keeping the dustproof net 210 in a clean state, thereby ensuring and improving the ventilation and heat dissipation effect of the condenser 111.
