Description

Technical Field

[0001] The present application relates to the technical field of car wash machines, and in particular to a small contactless car wash machine. Background Art

[0002] First, when a car washer uses a rotating brush or bristles for cleaning, due to the friction between the bristles and the car body, if the brush quality is poor or the cleaning method is improper, it is easy to cause scratches or scratches on the car paint. Especially when there are large gravel or particles on the surface of the car body, these particles will be hit by the high-speed rotating bristles and leave scratches on the car paint. This not only affects the appearance of the vehicle, but may also cause permanent damage to the car paint.

[0003] Secondly, the sewage generated by existing car washing machines during the car washing process is often not effectively collected and cleaned. When washing a car, a large amount of water and detergent are used, which contain impurities such as dirt and grease on the surface of the car body. If these sewage flows directly out of the workshop, it will not only cause environmental pollution, but may also have a negative impact on the surrounding environment. At the same time, there are certain problems with the cleaning of the floor of the car wash. Since the sewage and impurities generated during the car washing process will be scattered on the ground, long-term accumulation will cause the ground to become slippery and easy to get dirty, which not only increases the difficulty of cleaning, but may also affect the normal operation of the car washing machine.

[0004] In view of the above problems, a small contactless car washing machine is now designed. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The embodiment of the present application provides a small contactless car washing machine, which can solve the problem in the related art that when using a rotating brush or bristles for cleaning, the car paint is easily scratched or scratched, and it is inconvenient to collect and clean the wastewater after cleaning.

[0025] See also Figure 1-Figure 3A small contactless car washing machine comprises: a cleaning workshop 1 and a group of slide rails 2, wherein the cleaning workshop 1 is provided with a cleaning station 3 for parking vehicles, a group of the slide rails 2 are slidably provided with a frame 4 and a swing arm 5 rotatably provided at the bottom of the frame 4, the swing arm 5 is provided with a spray pipe 6, the spray pipe 6 is used for spraying cleaning foam and clean water, the frame 4 is provided with a driving mechanism 7, the driving mechanism 7 is used to drive the frame 4 to move along the length direction of the slide rail 2; a sewage trough 8 is provided inside the cleaning station 3, a plurality of drainage holes 9 connected with the sewage trough 8 are opened on the cleaning station 3, a scraping assembly 10 located above the drainage hole 9 is provided on the cleaning station 3, and the scraping assembly 10 is used to scrape impurities above the cleaning station 3.

[0026] The car washing machine realizes the flexible movement of the spray pipe 6 on the washing station 3 through the design of the slide rail 2 and the frame 4. This design not only ensures all-round coverage during the car washing process, but also greatly improves the washing efficiency.

[0027] Secondly, the sewage trough 8 and the drainage hole 9 arranged inside the cleaning station 3 enable the sewage generated during the car washing process to be smoothly discharged into the sewage trough 8, thereby avoiding the problem of sewage overflow.

[0028] The setting of the scraping component 10 can further scrape off impurities above the cleaning station 3. Foam and dust flow into the sewage tank 8 through the drainage hole 9. Large particles of impurities accumulate at both ends of the cleaning station 3, which facilitates the cleaning work of the staff and ensures the cleanliness of the car washing environment.

[0029] In actual operation, when the vehicle is parked on the cleaning station 3, the driving mechanism 7 starts to work, driving the frame 4 to move along the slide rail 2. At the same time, the spray pipe 6 on the swing arm 5 starts to spray cleaning foam and clean water. These cleaning liquids can effectively remove stains, dust and other impurities on the vehicle body.

[0030] During the cleaning process, the scraping component 10 is used to scrape off impurities and excess water above the cleaning station 3. Excess water, foam and dust flow into the sewage trough 8, and impurities accumulate on both sides of the cleaning station 3. In this way, not only the cleaning effect can be ensured, but also sewage and impurities can be prevented from clogging the drainage hole 9.

[0031] The contactless design avoids scratches and damages that may occur in traditional car washing methods, and provides good protection for the car paint. At the same time, the entire car washing process does not require human intervention, which greatly saves labor costs and improves car washing efficiency.

[0032] In addition, it can effectively collect sewage generated during the car washing process to avoid sewage overflow and environmental pollution, and collect impurities to facilitate cleaning by staff.

[0033] It should be noted that the spray pipe 6 in this embodiment is L-shaped, and a plurality of spray holes are provided on the side of the spray pipe 6 close to the cleaning station 3. One end of the spray pipe 6 is connected to an external liquid supply hose, and the bottom of the swing arm 5 is open to avoid blocking the high-pressure foam or high-pressure clean water sprayed from the spray pipe 6.

[0034] In another embodiment, a plurality of blowers are arranged on the frame 4 in this embodiment, and the air outlet pipes of the blowers face the cleaning station 3 for drying the cleaned vehicle.

[0035] The spray pipe 6 is in an L-shape, which ensures that the spray pipe 6 can cover a wider area during the cleaning process and can effectively avoid cleaning dead corners, ensuring that every part of the vehicle body can be fully cleaned.

[0036] A plurality of spray holes are provided on one side of the spray pipe 6 close to the cleaning station 3. The function of these spray holes is to spray cleaning foam and clean water evenly, ensuring that the cleaning liquid can fully cover and penetrate the surface of the vehicle body, thereby effectively removing stains and impurities.

[0037] One end of the spray pipe 6 is connected to the external liquid supply hose, which enables the car washing machine to continuously and stably obtain cleaning liquid, ensuring the continuity and efficiency of the cleaning process. The external liquid supply hose can be easily connected to the liquid supply system of the car washing machine to realize automatic liquid supply without manual operation, greatly improving the efficiency of car washing.

[0038] In addition, the bottom of the swing arm 5 is designed to be open to avoid blocking the high-pressure foam or high-pressure water sprayed from the spray pipe 6. Under high pressure, the cleaning liquid will be sprayed at a higher speed and with greater impact force. If the bottom of the swing arm 5 is closed, it may hinder the spraying of the cleaning liquid and affect the cleaning effect. The open design ensures that the cleaning liquid can be sprayed smoothly and directly act on the surface of the vehicle body, thereby improving the cleaning efficiency and quality.

[0039] Specifically, the driving mechanism 7 in this embodiment includes a belt 71, two pulleys 72, a synchronous pulley 73 and several driving motors 74, the belt 71 is arranged above the slide rail 2, the two pulleys 72 and the synchronous pulley 73 are rotatably set on the frame 4, the driving motors 74 are arranged on the frame 4 in sequence, and the output shafts of several driving motors 74 are respectively connected to the pulleys 72 and the synchronous pulleys 73, and the driving motors 74 are used to drive the pulleys 72 and the synchronous pulleys 73 to rotate, wherein the synchronous pulley 73 is located at the lower part between the two pulleys 72, and the belt 71 passes through the top of the pulley 72 on one side, the bottom of the synchronous pulley 73 and the top of the pulley 72 on the other side in sequence.

[0040] The driving mechanism 7 is mainly composed of a belt 71, two pulleys 72, a synchronous pulley 73 and a plurality of driving motors 74, which ensure that the frame 4 can move stably and efficiently along the slide rail 2, thereby driving the spray pipe 6 to fully clean the vehicle.

[0041] In actual operation, the belt 71 is arranged above the slide rail 2 to form a continuous transmission path. The two pulleys 72 and the synchronous pulley 73 are installed on the frame 4 and can rotate freely. These wheels are closely matched with the belt 71 and together constitute the core transmission part of the drive mechanism 7. The drive motor 1 74 is arranged on the frame 4 in an orderly manner. Their output shafts are respectively connected to the pulley 72 and the synchronous pulley 73. When the drive motor 1 74 is started, they will drive the pulley 72 and the synchronous pulley 73 to rotate. Since the belt 71 is closely connected to these wheels, the belt 71 will also move accordingly. In this way, the frame 4 is driven by the belt 71 and moves along the slide rail 2.

[0042] It should be noted that by reasonably setting the number and position of the driving motors 74 and optimizing the parameters of the belt 71, the pulley 72 and the synchronous pulley 73, it can be ensured that the driving mechanism 7 has sufficient driving force and stability, thereby meeting various needs of the car washing machine during the cleaning process.

[0043] Preferably, Figure 2 and Figure 3 As shown, in this embodiment, a rotating mechanism 11 is arranged on the frame 4, and the rotating mechanism 11 includes a driving motor 111 and a reducer 112. The driving motor 111 and the reducer 112 are both arranged on the frame 4, and the output shaft of the driving motor 111 is connected to the input shaft of the reducer 112, and the output shaft of the reducer 112 is connected to the swing arm 5.

[0044] A rotating mechanism 11 is specially provided on the frame 4, and this mechanism provides the swing arm 5 with a rotating power, thereby realizing multi-angle and all-round cleaning of the spray pipe 6 during the cleaning process.

[0045] The rotating mechanism 11 is mainly composed of a driving motor 111 and a reducer 112. The driving motor 111 serves as a power source, and its output shaft is connected to the input shaft of the reducer 112. The reducer 112 reduces the output speed of the driving motor 111 and increases the output torque to meet the power and speed requirements for the rotation of the swing arm 5. The output shaft of the reducer 112 is directly connected to the swing arm 5 to ensure the effective transmission of the driving force. When the driving motor 111 is started, the swing arm 5 can rotate smoothly and accurately through the deceleration and torque-increasing effect of the reducer 112.

[0046] Understandable, such as Figure 1As shown, the cleaning station 3 in this embodiment includes two parking platforms, which are arranged opposite to each other on the cleaning workshop 1, and a plurality of drainage holes 9 are distributed in the middle and on both sides of the two parking platforms.

[0047] The two parking platforms of the cleaning station 3 are relatively arranged on the cleaning workshop 1, so that the car washing machine can adapt to vehicles of different sizes and types. Whether it is a small car or a large SUV, it can find a suitable parking position between the two parking platforms, thereby ensuring the smooth progress of the cleaning process.

[0048] The drainage holes 9 are distributed in the middle of the two parking platforms and on both sides thereof. Such a layout enables the sewage and impurities generated during the cleaning process to flow quickly and effectively into the sewage tank 8 through the drainage holes. Whether it is the water flow on the top or the side of the vehicle, it can be quickly drained away to avoid water accumulation or sewage overflow.

[0049] To further explain, Figure 5 As shown, the scraping assembly 10 in this embodiment includes a linear slide rail 101, a transfer rod 102 and three scrapers 103, the linear slide rail 101 is arranged on the top wall inside the sewage trough 8, the three scrapers 103 are slidably arranged above the drainage hole 9 in sequence, the transfer rod 102 is connected to the linear slide rail 101, and the other end of the transfer rod 102 is connected to the corresponding scraper 103, wherein the three scrapers are arranged in the middle and on both sides of the two parking platforms in sequence, the transfer rod 102 is M-shaped, and three sliding holes connected to the sewage trough 8 are opened in sequence on the cleaning workshop 1, and the three ends above the transfer rod 102 extend from the corresponding sliding holes and are connected to the scrapers 103 respectively.

[0050] The scraping assembly 10 is mainly composed of a linear guide rail 101 , a transfer rod 102 and three scrapers 103 , which work together to ensure that the moisture and impurities on the cleaning station 3 can be effectively scraped off.

[0051] The linear slide 101 is arranged on the top wall inside the sewage trough 8, and the three scrapers 103 are slidably arranged above the drainage hole 9 in sequence, so that the scraper 103 can cover a wider area, ensuring the comprehensiveness and efficiency of the wiping effect. The adapter rod 102 is a key component connecting the linear slide 101 and the scraper 103. The adapter rod 102 is connected to the linear slide 101, and the other end is connected to the corresponding scraper 103, so as to form a complete wiping system. The adapter rod 102 is M-shaped. This design enables it to simultaneously connect and control the movement of the three scrapers 103 to ensure their coordination and consistency during the wiping process. In addition, three sliding holes connected to the sewage trough 8 are opened in sequence on the cleaning workshop 1. The three ends above the adapter rod 102 extend through these sliding holes and are connected to the scraper 103, so that the scraper 103 can move more flexibly.

[0052] During the car washing process, the scraping assembly 10 starts to work, and the transfer rod 102 starts to move under the guidance of the linear slide rail 101, driving the three scrapers 103 to slide along the surface of the cleaning workshop 1. The blade part of the scraper 103 fits tightly against the surface of the cleaning workshop 1, and the residual moisture and impurities are scraped off by the scraping action. The scraped moisture, foam and dust then flow into the sewage tank 8 through the drainage hole 9, thereby collecting the sewage. Large particles of impurities remain at both ends of the cleaning station 3, which is convenient for the staff to collect.

[0053] In this embodiment, the sewage tank 8 is connected with a drain pipe 12 and a silt discharge pipe 13 . The drain pipe 12 is used to discharge the sewage on the surface of the sewage tank 8 , and the silt discharge pipe 13 is used to extract impurities from the bottom of the sewage tank 8 .

[0054] The main function of the drain pipe 12 is to discharge the sewage on the surface of the sewage tank 8. During the car washing process, the cleaning liquid and the stains on the surface of the vehicle are washed down to form sewage containing a large amount of impurities. The sewage will first accumulate inside the sewage tank 8. After sedimentation, the sewage on the surface can be quickly and effectively discharged through the setting of the drain pipe 12, avoiding the accumulation and overflow of sewage.

[0055] The function of the silt discharge pipe 13 is to extract impurities at the bottom of the sewage tank 8. During the car washing process, some heavier impurities, such as mud, gravel, etc., will be deposited at the bottom of the sewage tank 8. Through the setting of the silt discharge pipe 13, the impurities at the bottom of the sewage tank 8 can be regularly extracted and cleaned.

[0056] It is understood that the drain pipe 12 includes a pipe body, a connector and a valve. The pipe body is usually made of corrosion-resistant and wear-resistant materials to ensure stability and reliability in long-term use. The connector is used to connect the drain pipe 12 to the sewage tank 8, and is usually connected by flanges, clamps, etc. to ensure the firmness and sealing of the connection. The valve is installed at the outlet of the drain pipe 12 to control the discharge of sewage. Manual valves or automatic valves can be set as needed to flexibly adjust the discharge speed and discharge volume of sewage.

[0057] The silt removal pipe 13 includes a pipe body, a silt extraction pump, connectors and a control system. The pipe body is also made of corrosion-resistant and wear-resistant materials to adapt to the complex environment of bottom impurities. The silt extraction pump is the core component of the silt removal pipe 13, which is responsible for generating sufficient suction to extract impurities at the bottom of the sewage tank 8. The silt extraction pump is usually installed at the end of the pipe body and is tightly connected to the pipe body through connectors. The control system is used to control the working state of the silt extraction pump, and can be set as needed. Timing start, manual start or sensor automatic start and other modes to ensure the timeliness and effectiveness of silt removal work.

[0058] In addition, in order to ensure the normal operation and convenient maintenance of the drainage pipe 12 and the silt discharge pipe 13, an observation port and a cleaning port can also be set on the pipe body. The observation port is used to observe the flow of sewage or impurities in the pipe so as to find problems in time and take measures. The cleaning port is used to regularly clean and maintain the pipe to prevent blockage or damage.

[0059] It should be noted that, in order to treat the discharged sewage, the drainage pipe 12 and the silt discharge pipe 13 in this embodiment are connected to the external sewage circulation system for sewage circulation.

[0060] The system includes pre-treatment module, main treatment module, deep treatment module and recycling module to ensure that sewage and impurities are effectively treated and water resources are recycled.

[0061] Among them, the pretreatment module mainly removes large particles of impurities and suspended solids in sewage through equipment such as grilles and sedimentation tanks, reducing the difficulty of subsequent treatment. At the same time, a reasonable flow regulating device is set to ensure that sewage enters the treatment system at a stable flow rate; the main treatment module can use physical, chemical or biological methods to further remove soluble pollutants in sewage. For example, tiny impurities and harmful substances are removed through equipment such as sand filters and activated carbon filters; hardness ions are removed by methods such as ion exchange resins or lime to prevent equipment scaling; ultraviolet rays, ozone and other technologies are used to kill bacteria, viruses and other microorganisms to ensure water quality safety; the deep treatment module can use more advanced technologies, such as membrane separation technology, advanced oxidation technology, etc., to further purify water quality and make it reach higher reuse standards; the recycling module uses equipment such as circulating pumps to transport the treated water to various equipment that needs water, so as to achieve the recycling of water resources.
