[0024] The following describes in detail, with reference to the accompanying drawings, the vehicle glass cleaning device 10 and the vehicle according to an embodiment of the present invention.

[0025] Reference Figures 1-6 As shown, the vehicle window cleaning device 10 includes: a window frame 1 and a piping system 2. The window frame 1 has a frame flow channel 121 and a first spray hole 111. The first spray hole 111 is connected to the frame flow channel 121 and faces the door glass 201 adjacent to the window frame 1. The piping system 2 includes a main pipeline 21, an air supply device 22 and a liquid supply device 23. The air supply device 22 and the liquid supply device 23 are selectively connected to the frame flow channel 121 through the main pipeline 21. The main pipeline 21 is equipped with a heater 211 and a check valve 212. The check valve 212 is used to allow unidirectional flow from the main pipeline 21 to the frame flow channel 121.

[0026] Specifically, the vehicle glass cleaning device 10 can be used in a vehicle. The window frame 1 can be installed in the vehicle door 20. The window frame 1 can support and fix the vehicle door glass 201. The window frame 1 has a frame flow channel 121 and a first spray hole 111. The first spray hole 111 is connected to the frame flow channel 121 and is arranged facing the door glass 201. The pipeline system 2 can be used to provide liquid, gas or other fluids to the frame flow channel 121 so that the fluid can flow through the frame flow channel 121 to the first spray hole 111, and then be sprayed onto the door glass 201 through the first spray hole 111 to achieve the cleaning function of the door glass 201, so that the driver and passengers can clearly see the road conditions outside the vehicle and the exterior rearview mirror 202 through the door glass 201.

[0027] The pipeline system 2 includes a main pipeline 21, an air supply device 22, and a liquid supply device 23. The air supply device 22 and the liquid supply device 23 are selectively connected to the frame flow channel 121 through the main pipeline 21 to achieve selective air and liquid spraying on the door glass 201, ensuring the cleanliness of the door glass 201 and preventing the door glass 201 from obstructing the view.

[0028] The main pipeline 21 is equipped with a heater 211, which can be used to heat the fluid flowing through the main pipeline 21 to increase the fluid temperature, thereby enabling the heating function of the door glass 201. This can be used for defogging, defrosting, and preventing icing of the door glass 201. In addition, the heater 211 can also be used to heat the main pipeline 21 to remove residual moisture inside the main pipeline 21, reducing the risk of corrosion and scale buildup.

[0029] The main pipeline 21 is equipped with a check valve 212, which is used to ensure one-way flow from the main pipeline 21 to the frame flow channel 121. In other words, the check valve 212 is a one-way valve. The fluid supplied by the air supply device 22 and the liquid supply device 23 can flow through the check valve 212 of the main pipeline 21 to the frame flow channel 121 and the first nozzle 111. Dust, rainwater and other objects outside the vehicle cannot pass through the check valve 212 on the main pipeline 21 after entering the first nozzle 111 and the frame flow channel 121. This prevents dust, rainwater and other substances from entering the air supply device 22 and the liquid supply device 23, and avoids damage or contamination to the air supply device 22 and the liquid supply device 23.

[0030] When the air supply device 22 is connected to the frame flow channel 121 via the main pipe 21, the air supply device 22 provides pressurized gas, such as compressed air, to the frame flow channel 121 through the main pipe 21. This gas then passes through the frame flow channel 121 and is sprayed onto the door glass 201 through the first nozzle 111. This air jet cleans the door glass 201, quickly removing rainwater, droplets, and dust. In rainy weather, this prevents rainwater from adhering to the surface of the door glass 201, ensuring its transparency and improving vehicle safety. Furthermore, when fogging or frost occurs on the door glass 201, the heater 211 can be activated to heat the gas, increasing its temperature. The heated gas, when sprayed onto the door glass 201, provides rapid defogging and defrosting.

[0031] When the liquid supply device 23 is connected to the frame flow channel 121 via the main pipe 21, the liquid supply device 23 provides a pressurized liquid, such as pure water or glass cleaning fluid, to the frame flow channel 121 through the main pipe 21. This allows the liquid to pass through the frame flow channel 121 and be sprayed onto the door glass 201 through the first nozzle 111, thus rinsing the door glass 201 and removing dirt. Additionally, when the outside temperature is below freezing, the heater 211 can be activated to raise the temperature of the liquid. The heated liquid is less likely to freeze after being sprayed onto the door glass 201, reducing the risk of icing.

[0032] It should be noted that after each spraying of liquid onto the door glass 201, the car glass cleaning device 10 can spray air again to clean the main pipeline 21 and remove any residual moisture inside the main pipeline 21. The air spray can also remove residual droplets on the door glass 201 caused by the liquid spraying, preventing the door glass 201 from obstructing the view. At the same time, the heater 211 can also be turned on during or after the air spraying to further remove any residual moisture inside the main pipeline 21, reducing the risk of corrosion and scale buildup in the main pipeline 21.

[0033] Understandably, the space inside the window frame 1 is limited, the main pipeline 21 is located outside the window frame 1, and the heater 211 is located on the main pipeline 21 to facilitate the arrangement and maintenance of the heater 211. In addition, a larger volume and power heater 211 can be used to improve heating efficiency. At the same time, the heater 211 can be used to heat the main pipeline 21 as well as the liquids and gases flowing through the main pipeline 21, so as to realize the reuse of the heating function of the heater 211, and has functions such as defogging, defrosting, preventing icing, and reducing corrosion of the main pipeline 21.

[0034] According to the embodiment of the present invention, the vehicle glass cleaning device 10 has an air supply device 22 and a liquid supply device 23 that are selectively connected to the frame flow channel 121 through the main pipeline 21. The fluid can flow through the frame flow channel 121 to the first spray hole 111, and then be sprayed onto the door glass 201 through the first spray hole 111 to achieve the cleaning function of the door glass 201 and avoid the door glass 201 from obstructing the view. The main pipeline 21 is equipped with a heater 211 to achieve functions such as defogging, defrosting, preventing icing, and reducing corrosion of the main pipeline 21. This helps to improve the functionality, reliability and service life of the vehicle glass cleaning device 10 and enhance the product competitiveness.

[0035] In some embodiments of this utility model, reference is made to Figures 1-5 As shown, window frame 1 is a door triangular window frame that is at least partially located on the front side of door glass 201.

[0036] Specifically, the triangular window frame of the car door is at least partially installed on the front side of the door glass 201. When the first nozzle 111 sprays fluid onto the door glass 201, the fluid moves backward. The direction of fluid movement is the same as the direction of airflow relative to the vehicle when it is moving, thereby reducing the resistance of the fluid spraying onto the door glass 201 and improving the cleaning effect.

[0037] In some other embodiments of this utility model (not shown in the figure), the window frame 1 may also be a door window frame that supports the door glass 201 around the entire outer side of the door glass 201.

[0038] In some embodiments of this utility model, reference is made to Figure 3 and Figure 5As shown, there are multiple first nozzles 111, and the multiple first nozzles 111 are arranged at intervals along the height direction of the window frame 1.

[0039] Specifically, the number of first spray holes 111 can be two, three, five, etc. Multiple first spray holes 111 can be arranged at intervals along the height direction of the window frame 1, that is, the height of each first spray hole 111 is different, so that each first spray hole 111 can face different areas of the door glass 201. Multiple first spray holes 111 can spray liquid or air onto different areas of the door glass 201, which can achieve cleaning of multiple positions of the door glass 201, thereby improving the cleaning effect of the door glass 201.

[0040] In some embodiments of this utility model, the aperture D1 of the first spray hole 111 satisfies the relationship: 0.5mm≤D1≤1.2mm.

[0041] Specifically, when D1 < 0.5 mm, the orifice diameter D1 of the first nozzle 111 is relatively small, resulting in higher processing precision and cost for the first nozzle 111. Furthermore, the resistance to liquid flow through the first nozzle 111 is greater, and the first nozzle 111 is also more prone to clogging by impurities. When D1 > 1.2 mm, the orifice diameter D1 of the first nozzle 111 is relatively large, leading to a decrease in the pressure and flow rate of gas and liquid as they pass through the first nozzle 111, thus weakening the cleaning effect of the fluid on the door glass 201.

[0042] In the above embodiment, the aperture D1 of the first nozzle 111 satisfies the relationship: 0.5mm≤D1≤1.2mm. D1 can be 0.5mm, 0.7mm, 0.9mm, or 1.2mm, etc., so that the aperture D1 of the first nozzle 111 is moderate. The first nozzle 111 has a microporous structure and can accommodate the needs of air jet and liquid jet, achieving a better cleaning effect on the car door glass 201. At the same time, the first nozzle 111 is relatively easy to process and is not easily blocked by impurities.

[0043] In some embodiments of this utility model (not shown in the figures), the window frame 1 also has at least one second spray hole, which is connected to the frame flow channel 121 and faces the exterior rearview mirror 202 adjacent to the window frame 1.

[0044] Specifically, the second nozzle and the first nozzle 111 can spray gas and liquid into the frame channel 121 together. The first nozzle 111 is used to clean the door glass 201 adjacent to the window frame 1, and the second nozzle is used to clean the mirror glass of the exterior rearview mirror 202 adjacent to the window frame 1, so as to realize the functionality of the vehicle glass cleaning device 10.

[0045] It is understandable that the environment and temperature of the door glass 201 and the exterior rearview mirror 202 adjacent to the window frame 1 are basically the same. Therefore, the fluid sprayed outward through the first nozzle 111 and the second nozzle can respectively clean the door glass 201 and the exterior rearview mirror 202, defogging, defrosting, and preventing icing.

[0046] For example, when the air supply device 22 is connected to the frame flow channel 121 via the main pipe 21, the air supply device 22 provides pressurized gas to the frame flow channel 121 via the main pipe 21. This allows the gas to pass through the frame flow channel 121 and be sprayed from the first nozzle 111 onto the door glass 201 and from the second nozzle onto the exterior rearview mirror 202. This airflow effectively blows away rainwater, droplets, and dust from the door glass 201 and the exterior rearview mirror 202. Furthermore, when fogging or frost forms on the door glass 201 and the exterior rearview mirror 202, the heater 211 can be activated to heat the gas, thereby increasing its temperature. The heated gas, when sprayed onto the door glass 201 and the exterior rearview mirror 202, can quickly defog and defrost.

[0047] When the liquid supply device 23 is connected to the frame flow channel 121 via the main pipe 21, the liquid supply device 23 provides pressurized liquid to the frame flow channel 121 through the main pipe 21. This allows the liquid to pass through the frame flow channel 121 and be sprayed from the first nozzle 111 onto the door glass 201 and from the second nozzle onto the exterior rearview mirror 202, thus rinsing the door glass 201 and exterior rearview mirror 202 and removing dirt. Additionally, when the outside temperature is below freezing, the heater 211 can be activated to heat the liquid, thereby raising its temperature. The heated liquid is less likely to freeze after being sprayed onto the door glass 201 and exterior rearview mirror 202, reducing the risk of icing.

[0048] In some embodiments of this utility model, the aperture D2 of the second spray hole satisfies the relationship: 0.5mm≤D2≤1.2mm. D2 can be 0.5mm, 0.7mm, 0.9mm, or 1.2mm, etc., so that the aperture D2 of the second spray hole is moderate. The second spray hole has a microporous structure and can accommodate the needs of air jet and liquid spray, achieving a better cleaning effect for the exterior rearview mirror 202. At the same time, the second spray hole is relatively easy to process and is not easily blocked by impurities.

[0049] In some embodiments of this invention, at least a portion of the piping system 2 is installed inside the door 20.

[0050] In some embodiments, the piping system 2 can be installed entirely inside the door 20 to reduce the maximum distance between the piping system 2 and the upper window frame 1 of the door 20, reduce the length of the main piping 21, and reduce the space occupied and layout cost of the vehicle glass cleaning device 10.

[0051] In other embodiments, reference is made to Figure 1 and Figure 2 As shown, the piping system 2 can also be partially installed inside the door 20 and partially installed in the front engine compartment of the vehicle. For example, the air supply device 22 and the liquid supply device 23 in the piping system 2 can be installed in the front engine compartment, and the main pipeline 21 can pass through the line interface 203 of the door 20. One end of the main pipeline 21 can be connected to the air supply device 22 and the liquid supply device 23, and the other end of the main pipeline 21 can be connected to the frame flow channel 121. It is more convenient to install the air supply device 22 and the liquid supply device 23 in the front engine compartment, so as to reduce the difficulty of arranging the air supply device 22 and the liquid supply device 23.

[0052] In some embodiments of this utility model, reference is made to Figure 2 As shown, the check valve 212 is located at one end of the main pipeline 21 near the flow channel 121 of the frame.

[0053] Specifically, the check valve 212 is located at one end of the main pipeline 21 near the frame flow channel 121, so that the check valve 212 is close to the window frame 1, preventing dust, rainwater and other substances from entering the main pipeline 21, avoiding blockage of the main pipeline 21 and the generation of scale, thereby improving the reliability and service life of the vehicle glass cleaning device 10.

[0054] In some embodiments of this utility model, reference is made to Figures 3-5 As shown, the window frame 1 includes a frame body 11 and an insert tube 12. The frame body 11 has a first spray hole 111. The insert tube 12 is connected to the frame body 11 as a whole and forms a frame flow channel 121. A part of the insert tube 12 extends out of the frame body 11 and communicates with the main pipeline 21. The other part of the insert tube 12 is embedded in the frame body 11 and communicates with the first spray hole 111.

[0055] Specifically, the frame body 11 can be an injection molded part, and the material of the frame body 11 can be PC-ABS (engineering plastic alloy), which has excellent heat and weather resistance, dimensional stability and impact resistance, as well as excellent processing fluidity, so as to facilitate the injection molding of the frame body 11. In addition, PC-ABS can also pass the corrosion resistance test of glass cleaning fluid to ensure the service life of the frame body 11.

[0056] The frame body 11 has a first nozzle 111. The first nozzle 111 structure can be formed by in-mold injection molding process during the injection molding of the frame body 11, or the first nozzle 111 can be processed by laser drilling or mechanical drilling after the frame body 11 is injection molded.

[0057] The insert 12 can be a metal tube or a nylon tube. The insert 12 can be integrated into the frame body 11 through in-mold injection molding. That is, the insert 12 can be pre-placed in the injection mold of the frame body 11, and then the mold is closed. Molten PC-ABS is injected into the injection mold, so that the frame body 11 and the insert 12 are combined into a whole part inside the mold, thereby reducing the complexity of the injection mold.

[0058] A frame flow channel 121 is formed inside the embedded tube 12. The inner diameter of the embedded tube 12 can be greater than or equal to 2 mm so that liquid and gas can pass smoothly through the frame flow channel 121. A part of the embedded tube 12 extends out of the frame body 11 and is connected to the main pipeline 21. The connection between the part of the embedded tube 12 extending out of the frame body 11 and the main pipeline 21 is convenient and easy to inspect and maintain. The other part of the embedded tube 12 is embedded in the frame body 11 and is connected to the first nozzle 111. The part of the embedded tube 12 embedded in the frame body 11 is integrally connected to the frame body 11 and can be provided with a pipe hole corresponding to the first nozzle 111. The fluid in the frame flow channel 121 of the embedded tube 12 can flow into its corresponding first nozzle 111 through the pipe hole.

[0059] In the above embodiment, the embedded tube 12 is connected to the frame body 11 as a whole to form a frame flow channel 121. A part of the embedded tube 12 extends out of the frame body 11 and communicates with the main pipeline 21. The other part of the embedded tube 12 is embedded in the frame body 11 and communicates with the first spray hole 111. The setting of the embedded tube 12 can reduce the manufacturing difficulty and cost of the window frame 1.

[0060] In some other embodiments of this utility model (not shown in the figure), the window frame 1 is an injection molded integral part. By designing its injection mold, it can form a frame flow channel 121 and a first spray hole 111 after injection molding. The frame flow channel 121 can be a cavity structure. The main pipeline 21 is inserted through the window frame 1 and communicates with the frame flow channel 121. The injection molded integral window frame 1 has high manufacturing efficiency and is suitable for mass production.

[0061] In some other embodiments of this utility model (not shown in the figure), the window frame 1 includes: a frame body 11 and a connecting pipe. The frame body 11 has a first spray hole 111. The connecting pipe has a frame flow channel 121. At least a portion of the connecting pipe is installed inside the frame body 11. The connecting pipe connects the first spray hole 111 and the main pipeline 21. The connecting pipe is installed on the frame body 11 by assembly, which allows for greater flexibility in design changes.

[0062] In some embodiments of this utility model, reference is made to Figure 2 and Figure 6 As shown, the pipeline system 2 also includes a three-way valve 24, which has an air supply valve port, a liquid supply valve port and a main valve port. The air supply device 22 is connected to the air supply valve port, the liquid supply device 23 is connected to the liquid supply valve port, and the main pipeline 21 is connected to the main valve port.

[0063] Specifically, when the three-way valve 24 connects the air supply valve port to the main valve port and disconnects the liquid supply valve from the main valve port, the compressed gas generated by the air supply device 22 can sequentially pass through the air supply valve port, the main valve port, the main pipeline 21, and the frame flow channel 121, and then be sprayed onto the door glass 201 through the first nozzle 111 to blow away rainwater, droplets, and dust from the door glass 201. Additionally, when fogging or frost occurs on the door glass 201, the heater 211 can be activated to heat the gas, thereby increasing its temperature. The heated gas, when sprayed onto the door glass 201, can quickly defog and defrost.

[0064] When the three-way valve 24 disconnects the air supply valve port from the main valve port and connects the liquid supply valve port to the main valve port, the liquid supplied by the liquid supply device 23 can sequentially pass through the liquid supply valve port, the main valve port, the main pipeline 21, and the frame flow channel 121, and then be sprayed onto the door glass 201 through the first spray hole 111 to rinse the door glass 201 and remove dirt from it. In addition, when the outside temperature is below the freezing point, the heater 211 can be turned on to heat the liquid, thereby raising the temperature of the liquid. The heated liquid is less likely to freeze after being sprayed onto the door glass 201, thus reducing the risk of the door glass 201 freezing.

[0065] The three-way valve 24 can realize the function of gas-liquid separation, so that liquid spraying and air spraying are not carried out at the same time. In addition, the opening and closing logic of the three-way valve 24 is that liquid spraying is not required after air spraying, and air spraying is required after liquid spraying, in order to remove the liquid remaining in the main pipeline 21 and the frame flow channel 121 after liquid spraying, and avoid corrosion of the main pipeline 21 and the frame flow channel 121.

[0066] In the above embodiments, the three-way valve 24 can be a solenoid valve. The three-way valve 24 can control whether the gas supply valve port and the liquid supply valve port are connected to the main valve port, so as to achieve selective connection between the gas supply device 22, the liquid supply device 23 and the main pipeline 21, thereby achieving selective connection between the gas supply device 22, the liquid supply device 23 and the frame flow channel 121.

[0067] In some embodiments of this utility model, reference is made to Figure 2 and Figure 6 As shown, the gas supply device 22 includes a gas supply pipeline 221 and a gas pump 222, with the gas pump 222 connected to the gas supply valve port through the gas supply pipeline 221.

[0068] Specifically, the air pump 222 can be used to draw in and compress air to increase the jet pressure of the first nozzle 111. The air supply line 221 can introduce compressed air into the air supply valve port so that the air pump 222 and the three-way valve 24 can be arranged separately in different positions. Optionally, the air pump 222 can be set up independently. The air pump 222 can also utilize the vehicle's original structure, such as the air pump of the vehicle's air suspension system or the air pump of the air conditioning system, to reduce the cost of the vehicle.

[0069] In the above embodiment, the air pump 222 is connected to the air supply valve port through the air supply pipeline 221. The air pump 222 and the three-way valve 24 can be flexibly arranged according to the space inside the vehicle to facilitate the assembly and maintenance of the vehicle glass cleaning device 10.

[0070] In some other embodiments of this utility model (not shown in the figures), the air supply device 22 includes: an air duct, the air outlet of which is connected to the air supply valve port, and the air inlet of which is located in the front engine compartment and faces the air intake grille. When the vehicle moves forward, the air duct can guide the airflow entering from the air intake grille to the air supply valve port. When the air supply valve port is open, it can spray air onto the door glass 201, and the air supply device 22 consumes no additional energy. Optionally, the air inlet of the air duct can be located on the side of the vehicle's radiator away from the air inlet. The airflow is heated after exchanging heat with the radiator through the air intake grille, and then enters the air inlet of the air duct, which helps to increase the intake temperature of the air duct and reduce the energy consumption of the heater 211 when defogging and defrosting by jet spraying.

[0071] In some embodiments of this utility model, reference is made to Figure 2 and Figure 6 As shown, the liquid supply device 23 includes: a liquid supply pipeline 231, a liquid pump 232 and a liquid storage tank 233. The liquid inlet of the liquid pump 232 is connected to the liquid storage tank 233, and the liquid outlet of the liquid pump 232 is connected to the liquid supply valve through the liquid supply pipeline 231.

[0072] Specifically, the reservoir 233 can be used to store liquid, and the inlet of the pump 232 can draw the liquid stored in the reservoir 233. Then, the outlet of the pump 232 pumps the liquid to the supply valve through the supply line 231. The pump 232 can be installed on the reservoir 233. The supply line 231 connects the pump 232 and the supply valve, so that the pump 232 and the three-way valve 24 can be arranged separately in different positions of the vehicle. Optionally, the reservoir 233 and the pump 232 can be set up separately. The reservoir 233 and the pump 232 can also utilize the vehicle's original structure. For example, the reservoir 233 is a reservoir 233 for storing windshield washer fluid. The pump 232 is also used to provide power for spraying windshield washer fluid onto the windshield of the vehicle to reduce the cost of the vehicle.

[0073] In the above embodiment, the liquid pump 232 is connected to the liquid supply valve port through the liquid supply pipeline 231. The liquid pump 232 and the three-way valve 24 can be flexibly arranged according to the space inside the vehicle to facilitate the assembly and maintenance of the vehicle glass cleaning device 10.

[0074] In some embodiments of this invention, the heater 211 is covered by the outside of the main pipeline 21.

[0075] Specifically, the heater 211 can be an electric heating strip. The heater 211 is wrapped around the outside of the main pipeline 21 so that the heater 211 can be connected to electricity. The heater 211 does not come into direct contact with liquids, gases or other fluids in the main pipeline 21 to avoid corrosion of the heater 211, thereby helping to extend the service life of the heater 211.

[0076] In addition, the heater 211 covering the outside of the main pipe 21 can heat the main pipe 21 evenly, and then heat the fluid inside the main pipe 21, avoiding uneven heating of the main pipe 21, preventing local residual moisture inside the main pipe 21, and reducing the risk of corrosion and internal icing of the main pipe 21.

[0077] In some other embodiments of the present invention, the heater 211 includes a heating element and an electrical connection element. The heating element is disposed in the main pipeline 21, and the electrical connection element is electrically connected to the heating element outside the main pipeline 21. The electrical connection element can supply power to the heating element, and the heating element can directly heat the fluid inside the main pipeline 21 to improve the heating efficiency of the heater 211 and reduce the energy consumption of the heater 211.

[0078] In some embodiments of this utility model, the main pipeline 21 can be a nylon tube with an inner diameter of 4mm to 8mm, so that liquids and gases can pass smoothly through the main pipeline 21.

[0079] In some embodiments of this utility model, there are two window frames 1, which are respectively located on the left and right doors 20 of the vehicle, and the main pipeline 21 is connected to the frame flow channel 121 of each window frame 1.

[0080] Specifically, in the vehicle glass cleaning device 10, a pipeline system 2 and two window frames 1 can be installed. The two window frames 1 are respectively installed on the left and right doors 20 of the vehicle. The main pipeline 21 can be a Y-shaped pipe. One end of the main pipeline 21 can be selectively connected to the air supply device 22 and the liquid supply device 23 through a three-way valve 24. The other two ends of the main pipeline 21 are respectively connected to the frame flow channels 121 of the two window frames 1.

[0081] In the above embodiment, the two window frames 1 can share the same piping system 2 to reduce the weight and cost of the vehicle glass cleaning device 10.

[0082] In some embodiments of this utility model, reference is made to Figure 2As shown, the vehicle glass cleaning device 10 also includes a controller 3, which is communicatively connected to the three-way valve 24, the air supply device 22, the liquid supply device 23, and the heater 211. Users can send control commands to the controller 3 through the vehicle's central control screen, voice, instrument panel buttons, etc. The controller 3 can control the three-way valve 24, the air supply device 22, the liquid supply device 23, and the heater 211 to complete cleaning, defogging, defrosting and other functions according to the control commands.

[0083] In addition, the controller 3 can also communicate with the vehicle's rain sensor, outside temperature sensor, and vision sensor. The controller 3 can obtain information such as whether it is raining outside the vehicle and the amount of rain based on the rain sensor, whether the outside temperature of the vehicle is below freezing based on the outside temperature sensor, and whether the door glass 201 is dirty, fogged, or frosted based on the vision sensor. Based on the above information, the controller 3 can control the three-way valve 24, air supply device 22, liquid supply device 23, and heater 211 to automatically perform air jet cleaning in rainy weather, automatically perform air jet and liquid cleaning when the door glass 201 is dirty, and automatically perform defogging and defrosting when the door glass 201 is fogged or frosted, thereby improving the intelligence of the vehicle glass cleaning device 10.

[0084] According to the vehicle glass cleaning device 10 of this utility model embodiment, the first spray hole 111 is integrated into the window frame 1. The first spray hole 111 and the window frame 1 are an integral structure, and the first spray hole 111 does not protrude from the window frame 1, which can avoid the first spray hole 111 from obstructing the door glass 201, and has better aesthetics and practicality. At the same time, the first spray hole 111 will not bring additional wind resistance, so as to ensure the aerodynamics of the vehicle.

[0085] When the door glass 201 is dirty, the car glass cleaning device 10 can spray liquid onto the door glass 201 for cleaning, and then spray room temperature gas to remove dust, dirt, and water stains from the door glass 201. The main pipeline 21 is designed with a heating function; after cleaning, the main pipeline 21 can be heated to remove water stains inside. In rainy weather, the car glass cleaning device 10 can spray room temperature gas to prevent rainwater from covering the door glass 201 and affecting the driver's visibility, improving safety and reducing energy consumption. When defrosting is required, heated gas can be sprayed to achieve defogging and defrosting functions in cold weather, offering the advantages of being fast, efficient, safe, and thorough.

[0086] The piping system 2 can be arranged outside the window frame 1 without occupying the internal space of the window frame 1, so as to avoid increasing the size of the window frame 1 and restricting its shape. It has the advantages of strong practicality, safety, low cost and easy maintenance.

[0087] It should be noted that the number and position of the first nozzle 111 can be adjusted according to user needs. The first nozzle 111 can be a circular hole or other polygonal holes, etc. The embedded pipe 12, main pipeline 21, liquid supply pipeline 231, and air supply pipeline 221 can be set to the corresponding lengths as needed. The three-way valve 24 only needs to achieve the diversion effect and can use valve bodies of various shapes such as Y-type and T-type. Its size can also be selected according to the interior space layout. The liquid pump 232 and air pump 222 can be selected according to the pressure requirements at the end of the first nozzle 111. The window frame 1 can be a plastic injection molded part, or a cast aluminum part formed by the aluminum casting process, or other material parts. In addition, each door 20 of the vehicle can be equipped with a window frame 1 with a frame flow channel 121 and the first nozzle 111.

[0088] A vehicle according to another embodiment of the present invention includes the vehicle glass cleaning device 10 of the above embodiment.

[0089] According to the vehicle of the present invention, the air supply device 22 and the liquid supply device 23 of the vehicle glass cleaning device 10 are selectively connected to the frame flow channel 121 through the main pipeline 21. The fluid can flow through the frame flow channel 121 to the first spray hole 111, and then be sprayed onto the door glass 201 through the first spray hole 111 to achieve the cleaning function of the door glass 201 and avoid the door glass 201 from obstructing the view. The main pipeline 21 is equipped with a heater 211 to achieve functions such as defogging, defrosting, preventing icing, and reducing corrosion of the main pipeline 21, thereby improving the functionality, reliability and service life of the vehicle and enhancing the product competitiveness of the vehicle.
