[0020] This embodiment provides a truck windshield washer, including a belt conveyor 1, a washing section, a drying section, and a controller.

[0021] Two belt conveyors 1 are arranged in parallel, passing through the cleaning chamber 2 and the drying chamber 3, and moving in the same direction at the same speed. Belt conveyors 1 are used to transport the truck's windshield 100 to the cleaning chamber 2 and the drying chamber 3. They use a flexible belt and are made entirely of 304 stainless steel, including the bearings. If stainless steel cannot be used for the parts, other materials that prevent water softening and rusting, such as rubber or nylon, are used. A sensor is installed at the inlet of belt conveyor 1 to detect the entry of the truck's windshield 100. The controller controls the operating time of the water pump based on the sensor's detection data.

[0022] The cleaning section includes a cleaning chamber 2, a water tank, spray components, a water pump, and water pipes; the drying section includes a drying chamber 3, an air knife assembly, a blower 19, and air ducts; the cleaning chamber 2 is located in front of the drying chamber 3; the water tank is located outside the cleaning chamber 2; multiple sets of spray components are installed inside the cleaning chamber 2 and arranged along the belt conveyor 1; each set of spray components includes an upper spray pipe and a lower spray pipe, the upper spray pipe is located above the belt conveyor 1, and the lower spray pipe is located below the belt conveyor 1, and spray holes are provided on both the upper and lower spray pipes; the inlet of the water pump is connected to the water tank, the outlet is connected to the water pipe, and the water pipe is connected to the upper and lower spray pipes; multiple sets of air knife assemblies are installed inside the drying chamber 3 and arranged along the belt conveyor 1; each set of air knife assemblies includes an upper air knife and a lower air knife, the upper air knife is located above the belt conveyor 1, and the lower air knife is located below the belt conveyor 1; the blower 19 is connected to the air knife assembly through air ducts. The washing section and the subsequent drying section are designed with a waterproof connection to isolate water mist.

[0023] The truck windshield 100 is placed at the inlet of the belt conveyor 1 and sequentially sent into the cleaning chamber 2 and the drying chamber 3. The spray assembly sprays and cleans the truck windshield 100, and then the air knife assembly dries the truck windshield 100. Finally, it is transported to the outlet of the belt conveyor 1, thus completing the cleaning of the truck windshield 100.

[0024] The cleaning section also includes a collection hopper; the collection hopper is installed in the cleaning chamber 2, with the upper water inlet located between the lower spray pipe and the water tank, and the lower water outlet connected to the water tank; the cross-section of the collection hopper gradually decreases from top to bottom.

[0025] Water sprayed from the sprinkler pipes and water dripping from the surface of the truck's windshield 100 can be collected in a collection hopper and flow into a water tank for reuse.

[0026] The multiple spray assembly is divided into a high-pressure spray assembly and an atmospheric pressure spray assembly 4; the high-pressure spray assembly is located in front of the atmospheric pressure spray assembly 4; the water tank is a high-pressure water tank; the water pump includes a high-pressure water pump and an atmospheric pressure water pump; the water pipe includes a high-pressure water pipe and an atmospheric pressure water pipe; the high-pressure water tank is connected to the inlet of the high-pressure water pump, the outlet of the high-pressure water pump is connected to the high-pressure water pipe, and the high-pressure water pipe is connected to the upper spray pipe and the lower spray pipe in the high-pressure spray assembly; the inlet of the atmospheric pressure water pump is connected to a pure water source, the outlet of the atmospheric pressure water pump is connected to the atmospheric pressure water pipe, and the atmospheric pressure water pipe is connected to the upper spray pipe and the lower spray pipe in the atmospheric pressure spray assembly 4.

[0027] The high-pressure spray system delivers powerfully impacted water jets that effectively remove stubborn dirt, grease, and other residues from the surface of the truck's windshield. After cleaning with high-pressure water, some small residues or water stains may remain on the glass surface. Rinsing again with normal-pressure water will thoroughly remove these residues and reduce water stain adhesion, ensuring a clean and smooth glass surface.

[0028] The high-pressure spray assembly is divided into high-pressure spray assembly I5 and high-pressure spray assembly II6, with high-pressure spray assembly I5 located in front of high-pressure spray assembly II6; the high-pressure water tank is divided into high-pressure water tank I7 and high-pressure water tank II8, with the water level in high-pressure water tank I7 being lower than that in high-pressure water tank II8, and high-pressure water tank I7 and high-pressure water tank II8 being connected by water supply pipe I, with water supply valve I installed on water supply pipe I; high-pressure water tank II8 is connected to the pure water source through water supply pipe II, with water supply valve II installed on water supply pipe II; the high-pressure water pump is divided into high-pressure water pump I9 and high-pressure water pump II10; the high-pressure water pipe is divided into high-pressure water pipe I11 and high-pressure water pipe II12; the collection hopper is divided into collection hopper I13 and collection hopper II14, with collection hopper I13 corresponding to high-pressure spray assembly I5, and collection hopper II14 corresponding to high-pressure spray assembly II6 and atmospheric pressure spray assembly 4.

[0029] The first high-pressure water rinse performs a preliminary wash, followed by a second high-pressure water rinse. This more effectively removes stubborn dirt, grease, and other deposits from the surface of the truck's windshield 100. The first high-pressure water flows into high-pressure water tank I7, while the second high-pressure water and normal-pressure water flow into high-pressure water tank II8. This separate collection process gradually increases the purity of the water in high-pressure water tank I7, high-pressure water tank II8, and the pure water source, ensuring a progressively improving cleaning effect from each stage of the three-stage cleaning process. The water level in high-pressure water tank I7 is lower than that in high-pressure water tank II8, allowing for a stepped overflow.

[0030] In this embodiment, two sets of high-pressure spray assembly I5, three sets of high-pressure spray assembly II6, and one set of atmospheric pressure spray assembly 4 are provided. The spray pipes are designed according to the shape of the truck's windshield 100 to ensure thorough rinsing. Water is only supplied when the truck's windshield 100 reaches between the upper and lower spray pipes.

[0031] The high-pressure water tank is made of 304 stainless steel and contains three independent float switches. Float switch I detects the low water level and provides start-up data for the water pump protection; float switch II detects the medium water level and provides start-up data for the water supply valve to open; float switch III detects the high water level and provides start-up data for the water supply valve to close. A conductivity meter is installed in high-pressure water tank II to detect the conductivity value of the water and provide start-up data for the opening and closing of water supply valve II.

[0032] Both the float switch and the conductivity meter are connected to the controller. The controller controls the water pump to stop working and issues a corresponding low water level alarm, as well as the opening and closing of the water supply valve, based on the corresponding detection data.

[0033] A filter is installed between the high-pressure water tank and the inlet of the high-pressure water pump. An automatic pressure relief valve is installed at the outlet of the filter. When the pumping stops, the automatic pressure relief valve opens automatically to prevent the windshield 100 of the truck from breaking due to continuous impact.

[0034] Cleaning chamber 2 is constructed entirely of 304 stainless steel to better control the cleaning water and prevent splashing. A water-resistant curtain is installed at the inlet of cleaning chamber 2 to prevent water splashing, and an exhaust fan 15 is installed above the inlet to connect cleaning chamber 2 to the outside and expel hot and humid air. Observation windows are installed on both sides of cleaning chamber 2, and lighting is installed inside for easy observation of the glass cleaning process and maintenance.

[0035] The air knife assembly consists of one air knife assembly I 16 and multiple air knife assemblies II 17. Air knife assembly I 16 is located at the inlet of drying chamber 3, with the upper and lower air knives vertically arranged to minimize water entry into the drying section. Air knife assembly II 17 is located behind air knife assembly I 16, with the upper and lower air knives of each air knife assembly II 17 angled in opposite directions (e.g., ...). Figure 1 The upper and middle air knives face the outlet of drying chamber 3, and the lower air knife faces the inlet of drying chamber 3. Each air knife can be manually adjusted independently to ensure that the glass is thoroughly dried.

[0036] An exhaust fan 15 is installed above the inlet of drying chamber 3, connecting it to the outside environment to expel the hot and humid air brought in by the cleaning section. Observation windows are installed on both sides of drying chamber 3, and lighting is installed inside to facilitate monitoring the drying process of the glass. Drying chamber 3 is equipped with sound insulation material to effectively prevent noise.

[0037] Fan 19 is installed inside fan housing 18, which is mounted above drying chamber 3, saving space. Fan housing 18 is equipped with sound insulation material to effectively reduce noise. Ladders and platforms are installed on the sides of drying chamber 3 for easy access and maintenance. Fan housing 18 is divided into a pressure equalization chamber, a fan chamber, and an air temperature adjustment device. Fan housing 18 is equipped with a differential pressure switch to detect whether the air filtration system is blocked. When the pressure difference between the inside and outside of fan housing 18 reaches a certain level, an alarm will sound to remind the user to replace or clean the air filtration system.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
