Description

Technical Field

[0001] This utility model relates to the field of intelligent self-service car wash technology, and more specifically, to an improved Internet-connected intelligent self-service car wash dust collection system. Background Technology

[0002] Self-service car wash machines are convenient and intelligent car washes where car owners wash their own vehicles. Self-service high-pressure car wash machines are a new type of car wash that uses coins or cards and manual labor to complete the wash. Domestic manufacturers are constantly innovating in terms of functionality, launching self-service high-pressure car wash machines with multiple functions such as water cleaning, foam application, waxing, vacuuming, and ozone disinfection.

[0003] Existing car wash vacuum systems often collect large amounts of debris and water when cleaning vehicles, causing sludge to form on the vacuum cleaner filter and blockages in the pipes due to the large debris. This leads to reduced vacuuming efficiency and an increased risk of equipment damage. Utility Model Content

[0004] To achieve the above objectives, in order to overcome the above deficiencies, one embodiment of the present invention provides an improved Internet-connected intelligent self-service car wash vacuuming system. This system aims to add a sorting and draining bucket to the external vacuuming pipe without altering the structure of the car wash's built-in vacuum cleaner. This sorting and draining bucket can be used in conjunction with the car wash's built-in vacuum cleaner to effectively separate and collect large particles of debris and moisture, thereby improving vacuuming efficiency and protecting the vacuuming equipment.

[0005] This utility model provides an improved Internet-connected intelligent self-service car wash vacuuming system, including a built-in vacuum cleaner for the car wash machine, and a self-service car wash machine sorting and draining box located outside the car wash machine and connected to the built-in vacuum cleaner.

[0006] The top of the external sorting and draining box is fixedly provided with a first connection port for connecting to the outlet pipe of the built-in vacuum cleaner of the car wash machine. The first side wall of the box is fixedly provided with a second connection port for connecting to the external vacuum pipe. The top of the inner cavity of the draining box is provided with a perforated plate that slopes downward. One end of the perforated plate is fixed to the top of the box, and the other end extends downward to the second side wall of the box, forming an inclined surface opposite to the second connection port. The first connection port opens above the triangular prism space formed by the perforated plate, the top wall of the box, and the second side wall. The front door of the external sorting and draining box is made of transparent material.

[0007] The external sorting and draining bin is equipped with at least one trash can with a transparent front wall inside, which is used to receive and store trash that falls off the perforated plate.

[0008] Furthermore, the transparent front door is connected to the housing via at least one locking mechanism.

[0009] Furthermore, the transparent front door, drain outlet, first connection port, and second connection port of the housing are all equipped with sealing devices to seal the housing during the vacuuming operation.

[0010] Furthermore, the perforated plate has evenly distributed holes, and one edge of each hole extends outward and downward to form an eave-shaped hole with an eave design.

[0011] Furthermore, the lower edge of the lower edge of the lower edge-shaped hole curls upward to form a rolled edge.

[0012] Furthermore, the surface of the perforated plate is provided with a hydrophobic coating.

[0013] Furthermore, a flow channel is provided on the second side wall of the box, which is adjacent to the lower end of the perforated plate and is used to guide the moisture on the perforated plate to the bottom of the box.

[0014] Furthermore, a boss is fixedly provided at the bottom of the inner cavity of the external sorting and draining box, and the trash can is movably placed on the boss. The bottom of the trash can is provided with a concave structure, and the concave structure is interference-fitted with the boss.

[0015] Furthermore, the concave structure has a spherical crown structure protruding into the inner cavity of the trash can at its center.

[0016] Furthermore, the concave structure edge forms a groove with the trash can wall, and a drainage hole is provided at the bottom of the groove to allow water to flow out from the bottom of the trash can, reducing the risk of decomposition of the trash inside the trash can.

[0017] The beneficial effects of this utility model are:

[0018] 1. Without changing the structure of the built-in vacuum cleaner of the car wash machine, this utility model adds a sorting drain bucket to the external vacuum pipe. The sorting drain bucket can be used in conjunction with the built-in vacuum cleaner of the car wash machine to effectively separate and collect large particles of garbage and water, improve vacuuming efficiency and protect the equipment.

[0019] 2. The container of this utility model is equipped with a transparent front door and the trash can has a transparent front wall, so that the staff can directly observe the garbage accumulation in the container without opening the door, thereby improving the maintenance efficiency of the staff.

[0020] 3. The top of the housing of this utility model is inclined downward with a perforated plate. The inclined surface of the perforated plate is opposite to the second connecting port, and the first connecting port opens above the triangular prism space formed by the inclined surface and the second side wall of the housing. This allows external dust- and moisture-laden airflow to pass through the perforated plate, where garbage and moisture are intercepted outside the perforated plate, while air containing small particles and dust enters the first connecting port through the perforations and then enters the outlet of the built-in vacuum cleaner of the car wash machine. This design significantly improves the sorting efficiency of garbage, moisture, and dust, thereby enhancing the overall suction performance and filtration effect of the vacuum cleaner housing.

[0029] As a specific example, an improved Internet-connected smart self-service car wash vacuum system includes a built-in vacuum cleaner installed inside the car wash machine, and an external sorting and draining tank 10 installed outside the car wash machine and connected to the built-in vacuum cleaner.

[0030] The built-in vacuum cleaner in car wash machines is a common and existing device, which is well known to those skilled in the art and will not be described in detail here.

[0031] 10 external sorting and draining boxes, as attached Figure 1-3 The diagram shows an external waste sorting and draining bin for use with a car wash machine's built-in vacuum cleaner. It includes a bin body with a transparent front door 11 for easy observation of the waste accumulation inside, allowing managers to visually inspect the bin without opening the door, thus improving inspection efficiency. The transparent front door 11 is connected to the bin body via at least one locking mechanism 12, which securely locks the front door 11 in a closed position, ensuring a tight seal. A first connection port 13 is fixed to the top of the bin body for connecting to the outlet pipe of the car wash machine's built-in vacuum cleaner. A second connection port 15 is fixed to the first side wall 14 of the bin body for connecting to the external suction pipe of the suction module. The external suction pipe connects to a suction nozzle, facilitating the suction system to remove dust and waste. Additionally, a drain outlet 16 is located at the bottom of the bin body, equipped with an electrically controlled sealed drain valve for draining water from the bin.

[0032] The transparent front door 11 of the enclosure, the first connection port 13, and the second connection port 15 are all equipped with sealing devices to ensure complete sealing of the enclosure during vacuuming operations and guarantee vacuuming efficiency. Furthermore, the diameter of the vacuum pipe connected to the second connection port 15 is increased to be larger than the existing vacuum pipe connected to the first connection port 13, which leads to the built-in vacuum cleaner of the car wash machine, to fully accommodate large debris. A filter screen with an area larger than the drain outlet 16 is covered above the drain outlet to filter out fine debris in the water. This filter screen is removable for easy cleaning by management personnel; it can be removed completely for thorough cleaning and convenient subsequent use. A wastewater pipe is connected to the drain outlet 16 to guide wastewater into the sewer system.

[0033] A perforated plate 17 is fixedly installed at the top of the container, tilting downwards. One end of the perforated plate 17 is fixedly connected to the top of the container, and the other end extends downwards to the second side wall 18 of the container, forming an inclined surface at a certain angle. The first connection port 13 at the top of the container is located above the "triangular prism" shaped space formed by this inclined surface, the top wall, and the second side wall 18. The perforated plate 17 has evenly distributed holes to allow airflow while intercepting large pieces of waste and moisture.

[0034] Furthermore, the holes can be elongated holes with an underglaze design. The length of the elongated holes is slightly less than the lateral width of the perforated plate 17. Guide channels are provided on the edges of the perforated plate 17 on both sides of the elongated holes to facilitate the rapid downward flow of water to the side wall of the box, reducing the chance of it being carried away by the airflow and sucked into the built-in vacuum cleaner.

[0035] The elongated perforation with a lower eave design is characterized by its extended edge, which extends outward and downward to form an eave similar to a rainproof awning. The function of this lower eave-shaped perforation is that when dust- and moisture-laden airflow passes through the perforated plate 17, debris and moisture are intercepted outside the perforation wall, while air containing small particles and dust enters the first connection port 13 through the opening below the perforation wall and then into the built-in vacuum cleaner of the car wash machine. This design improves the efficiency of debris and dust sorting and enhances the overall suction performance and filtration effect of the external sorting and draining box 10. Furthermore, the length of the lower eave can be 0.5 to 1 times the diameter of the perforation. This length, combined with the overall length of the elongated perforation, effectively guides particles to drip along the edge of the perforation without excessively increasing airflow resistance.

[0036] Furthermore, the perforated plate 17's perforated design includes a small rolled edge, which curls upwards along the outer edge of the perforation. This rolled edge increases the mechanical strength of the perforation edge, preventing damage during waste interception. Additionally, the rolled edge helps guide moisture along the perforation edge to the flow channels on the side wall of the bin, effectively separating moisture from dust and waste, reducing waste moisture and water accumulation within the bin, improving waste dryness and ease of subsequent processing. Furthermore, the perforated plate 17 has a hydrophobic coating that provides excellent hydrophobic properties, preventing water passing through it from remaining on the surface and instead causing it to drip quickly or be guided to the flow channels. This hydrophobic coating significantly reduces corrosion and contamination of the perforated plate 17, extending its service life. Simultaneously, the hydrophobic coating also reduces the adhesion of dust particles to the surface of the perforated plate 17, further improving the cleaning efficiency and filtration effect of the external sorting drain bin 10.

[0037] Furthermore, at least one flow channel is provided on the side wall of the container, which is adjacent to the lower end of the perforated plate 17, for guiding water on the perforated plate 17 to the bottom of the drain box. At one end of the rectangular perforated plate 17 near the door edge, a pre-defined notch is provided (the edge of the notch has a smooth transition curve). This notch is designed to provide a safe space, allowing personnel to avoid collisions with the edge of the perforated plate 17 when performing cleaning or maintenance tasks, such as retrieving the trash can 19 located below the perforated plate 17, thereby reducing the risk of injury. This notch design considers both the suspended layout of the perforated plate 17 and the personal safety of operators, achieving an organic combination of practicality and safety.

[0038] Inside the container, a trash can 19 is provided. This trash can 19 has at least one transparent front, allowing for easy observation of the trash accumulation inside, in conjunction with the transparent front door of the external sorting and draining bin 10. The trash can 19 receives and stores large pieces of trash that bounce off the perforated plate 17. A protrusion is provided at the bottom of the container's inner cavity, and the trash can 19 is movably placed on this protrusion. During cleaning, the trash can 19 can be removed from the container to empty the trash inside. The bottom of the trash can has a concave structure, which is interference-fitted with the protrusion. In the design of the concave structure of the trash can and the protrusion at the bottom of the draining bin, the interference fit, through slight dimensional differences, ensures the trash can is placed stably and is not easily tipped over. This design utilizes the tight connection characteristics of the interference fit to improve the stability of the trash can. Furthermore, the concave edge of the trash can 19 forms a groove with the trash can wall, and a drain hole is provided at the bottom of the groove. A spherical crown structure protruding into the inner cavity of the trash can is also provided at the center of the concave structure, which makes it easier for water to flow out from the inside of the trash can 19, thereby reducing the soaking time of large trash inside the trash can 19 and effectively reducing the risk of decomposition of large trash. The height of the protrusion is sufficient to allow water to flow out through the drain hole and be smoothly guided to the drain outlet 16 at the bottom of the container. A gap is left between the side wall of the trash can 19 and the side wall of the container to allow the water guided by the flow channel to flow directly to the bottom of the container.

[0039] The vacuum module works as follows:

[0040] Startup Phase: When the user activates the vacuuming function, the control motherboard receives the start command, the car wash machine activates the vacuuming module, and the normally open electrically controlled sealed drain valve is energized and closed. The car wash machine's built-in vacuum cleaner begins to work, sequentially passing through the first connection port 13 on the top of the external sorting and draining tank, the perforated plate 17, and the second connection port 15 on the side wall of the tank, generating negative pressure. This pressure is then drawn into the dusty airflow from the vehicle through the suction nozzle connected to the external vacuuming pipe of the vacuuming module.

[0041] Filtration and sorting stage: Dust-laden airflow passes through the holes on the perforated plate 17. Large waste is intercepted on the perforated plate 17 due to its size. A small amount of small particles and dust continue to move forward with the airflow, while moisture is guided to the guide channel on the side wall of the box due to gravity and the rolled edge design on the perforated plate 17.

[0042] Collection and drainage stage: Large pieces of trash bounce off the perforated plate 17 and fall into the trash can 19 located on the protrusion at the bottom of the container. Moisture is guided to the bottom of the container through the drainage channel.

[0043] Drainage and Recovery Phase: After vacuuming, the control board activates the electrically controlled sealed drain valve at the bottom of the bin according to the end command. The normally open electrically controlled sealed drain valve opens when power is off, allowing water accumulated at the bottom of the bin to drain through drain port 16, thereby emptying the bin of excess water and preventing large garbage items in the trash can 19 from soaking for extended periods. Prolonged soaking of garbage cans can lead to several adverse consequences, including the following:

[0044] Environmental pollution: Soaked garbage releases harmful substances such as heavy metals and organic pollutants, which can seep into groundwater or flow into rivers and lakes, damaging aquatic ecosystems; harmful components may seep into the soil, altering soil structure, reducing soil fertility, and affecting plant growth.

[0045] Odor problem: Garbage soaked for a long time will ferment and produce a foul odor, affecting the quality of life of surrounding residents and potentially causing public health problems. Garbage soaked for a long time will become softer and heavier, making garbage collection, transportation and disposal more difficult.

[0046] Safety hazards: Prolonged soaking of garbage may produce flammable gases, such as methane, posing a risk of explosion and fire.

[0047] Therefore, avoiding prolonged soaking of large trash cans 19 helps reduce negative impacts on the environment and public health. After drainage is complete, the drain outlet remains open, and the container can be connected to the outside through the second connection port 15 on the side wall of the container and the external vacuum pipe when not vacuuming, which helps moisture inside the container to continue to dissipate.

[0048] Shutdown and Standby Phase: The control motherboard shuts down the built-in vacuum cleaner, and the vacuum module enters standby mode, waiting for the next usage command.

[0049] Through the above-described process, this invention achieves the filtration of dust-laden airflow, the classified collection of large waste, and the effective removal of moisture, while ensuring the reusability of the equipment and environmental hygiene. Simultaneously, it effectively improves the existing problems of clogged, difficult-to-clean, and difficult-to-monitor vacuum cleaners in car wash machines, reducing the frequency of waste cleaning and operational difficulty, and significantly reducing the damage and repair frequency of the more expensive built-in vacuum cleaners in car wash machines.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
