Description

Technical Field

[0001] This invention relates to the field of car wash machine technology, and in particular to a fully automatic water-saving car wash machine. Background Technology

[0002] Traditional car wash machines clean vehicles entirely with a brush, which inevitably causes some damage to the vehicle. Furthermore, this method of cleaning the entire vehicle with a brush consumes a large amount of water, resulting in significant water waste. Currently, some cities have implemented policies to regulate water consumption and wastewater treatment in the car wash industry, aiming to conserve water resources and reduce wastewater discharge. Therefore, improving water usage and wastewater recycling in car wash machines is a key focus for the improvement of traditional car wash machines.

[0003] A Chinese invention patent, authorized by announcement number CN103264682B, discloses a base, two guide rails, two support columns, a top beam, a top brush bracket, a lifting motor, a top brush, a top brush motor, a side brush, and a side brush motor. The top and side brushes of this intelligent car wash machine can move in multiple directions to wash various parts of the vehicle. However, this car wash machine indiscriminately cleans both the relatively clean upper part and the relatively dirty lower part of the vehicle with the wash brush. While it can clean the vehicle surface, it causes significant damage to the vehicle's surface coating. Furthermore, it does not consider the issue of water waste during vehicle washing, indicating that this solution needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to address some shortcomings of existing technologies. This invention discloses a fully automatic water-saving car wash machine that uses a spray assembly to spray steam to wash the upper part of the vehicle, and uses a spray assembly to spray water from the falling water to clean the dirtier lower part of the vehicle. This solves the problems of existing car wash machines using a lot of water and causing significant damage to the vehicle during cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic water-saving car wash machine, comprising: a frame; a moving component, wherein the moving component is mounted on the frame;

[0006] A spray assembly for spraying steam at an angle to wash the upper surface of a vehicle is disposed on the movable assembly;

[0007] The washing assembly, which uses a spray assembly to spray water to wash the lower surface of the vehicle, is located below the spray assembly.

[0008] As an improvement, the moving component includes a longitudinal drive rod arranged along the Y-axis, a first slider, a transverse drive rod arranged along the X-axis, and a second slider; the longitudinal drive rod is connected to the frame; the first slider is slidably disposed on the longitudinal drive rod, and the transverse drive rod is rotatably disposed on the first slider; the second slider is slidably disposed on the transverse drive rod; the transverse drive rod is driven to rotate by a first motor, and the longitudinal drive rod is driven to rotate by a second motor.

[0010] As an improvement, the spray assembly includes an inverted L-shaped contour tube with multiple obliquely arranged oblique holes and nozzles arranged on the oblique holes. By cleaning the vehicle surface at an angle, the dirt on the vehicle surface is cleaned to one side, thus avoiding contamination of the cleaned area. The oblique cleaning improves the impact effect on the dirt on the vehicle surface.

[0011] As an improvement, the spraying assembly is connected to the first lifting component via a connecting pipe. An air slip ring is provided on the connecting pipe, and the air slip ring is rotatably connected to the connecting pipe.

[0016] A first elastic element is disposed at one end of the recycling tray and moves closer to the vehicle along with the recycling tray, abutting against the vehicle surface.

[0017] An elastic waterproof cloth is laid on a recycling tray, with one end of the elastic waterproof cloth connected to the end of a first elastic member and moving with the first elastic member and approaching the vehicle surface.

[0018] As an improvement, the recovery tray is connected to the lower end of the contour tube; the spray assembly moves and drives the recovery tray to move, the recovery tray located on one side of the spray assembly is longer than the other side of the spray assembly, and a second recovery tube is provided on the recovery tray; bristles are provided on the side of the recovery tray near the first elastic element; the elastic waterproof cloth is made of rubber or other non-metallic elastic materials.

[0019] As an improvement, a drying assembly for drying the washed vehicle surface is provided on one side of the spraying assembly; the drying assembly includes: an extraction pipe; and a spraying pipe;

[0020] Multiple absorbent strips are mounted on a movable assembly via extraction tubes and spray tubes. The extraction tubes, used to extract moisture from the inside of the absorbent strips, extend into the inside of the absorbent strips. The spray tubes, used to blow air onto the vehicle from the end of the absorbent strips for drying, extend into the absorbent strips and reach the end of the absorbent strips.

[0021] As an improvement, the extraction tube, spray tube, and water absorption strip are all made of soft materials that are easy to adhere to the vehicle surface. The water absorption strip is made of cotton or water-absorbing sponge. The surface of the section of the extraction tube that extends into the water absorption strip is evenly distributed with multiple holes to extract water from the water absorption strip and keep the water absorption strip absorbent for a long time.

[0022] As an improvement, the angle between the absorbent strip located on the edge side and the absorbent strip located in the middle is between ° and °.

[0023] As an improvement, the drying assembly further includes a width adjustment assembly for adjusting the total width of all absorbent strips; the width adjustment assembly includes:

[0024] A bidirectional drive rod with a forward spiral groove at one end and a reverse spiral groove at the other end;

[0025] Multiple sliding members are spaced apart on the bidirectional drive rod, and the sliding members at both ends are configured to cooperate with the spiral grooves on the bidirectional drive rod, and one side of the sliding member is configured to slide against the moving component.

[0026] A second elastic element is provided between adjacent sliding elements;

[0027] The extraction pipe and spray pipe on the same suction strip are connected to the corresponding sliding component.

[0028] As an improvement, a winding assembly is also provided on the side of the drying assembly; the winding assembly includes a winding roller and a pull rope; one end of the pull rope is connected to the end of the absorbent strip, and the other end is slidably disposed along the axial direction of the winding roller; the winding roller winding realizes the winding of the absorbent strip or the adjustment of the spray angle of the spray pipe at the end of the absorbent strip.

[0029] As an improvement, the lower surfaces of the upper moving component and the width adjusting component are provided with water-absorbing elements, and the water-absorbing elements are provided with water-drawing pipes, which are connected to the extraction pipes.

[0030] As an improvement, the washing assembly includes:

[0031] A scrubbing drive unit is arranged below the recycling assembly;

[0032] Mounting housing; the mounting housing is fitted over the wash drive component;

[0033] Car wash brushes, wherein the car wash brushes are evenly distributed on the mounting housing;

[0034] As an improvement, the mounting housing is equipped with a recessed groove. The washing drive component is a fifth motor, and the car wash brush is a foam brush. The foam brush does not absorb water or attract pebbles, providing good protection for the vehicle surface when cleaning. The foam brush is folded in the middle and inserted into the groove, with a protrusion inserted into the foam brush within the groove to secure it to the mounting housing, thus facilitating the installation, removal, and replacement of the car wash brush. The mounting housing covers the outer surface of the washing drive component, providing a certain degree of waterproof protection. Furthermore, the vibration of the washing component during washing drives the spray component to vibrate and spray, promoting the effective cleaning of dirt by the spray component.

[0035] As an improvement, a housing is provided outside the rack and covers the rack, and the housing is provided with a plurality of first recycling pipes.

[0036] As an improvement, the outer shell is equipped with a sensor door that automatically opens when a person or vehicle enters or exits; a drainage ditch is provided below the outer shell, which is buried underground to discharge and treat wastewater, reducing the impact of wastewater on the external environment of the car wash.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. This invention uses a spray assembly to spray steam to wash the upper part of a vehicle, and in conjunction with the spray assembly to spray water to clean the dirtier lower part of the vehicle, it achieves targeted overall cleaning of the vehicle, sterilization of the vehicle surface, and reduces damage to the upper surface of the vehicle during washing, thereby extending the service life of the vehicle surface coating and saving water.

[0039] 2. In this invention, the steam ejected by the spraying component falls to the recovery component, which recovers the wastewater that contains little or no engine oil. This wastewater can be pre-cleaned on some vehicles with a lot of surface dirt after simple sedimentation and filtration treatment, without the need to remove oil from the wastewater that contains little or no engine oil. This achieves water resource reuse and saves water, while reducing the cost of cleaning the recovered water.

[0040] 3. This invention utilizes the combined operation of an extraction pipe, a spray pipe, and a water-absorbing strip. The extraction pipe and spray pipe penetrate deep into the water-absorbing strip, allowing the strip to remain in a water-absorbing state for an extended period, enabling continuous wiping of multiple vehicles. After the water-absorbing strip absorbs most of the water stains on the vehicle surface, the spray pipe sprays dry air to dry the vehicle surface, achieving rapid one-time drying of the vehicle surface. This improves drying efficiency and effect while saving energy consumed by the spray pipe in spraying dry air.

[0041] 4. This invention adjusts the overall width of the absorbent strip using a width adjustment component, and adjusts the height of the absorbent strip or the angle of the spray nozzle by using a winding component. This allows the drying component to adapt to vehicles of different widths and heights, thus improving the application range of the car wash machine and the drying effect on the cleaned vehicle surface.

[0042] 5. This invention arranges water-absorbing components and water-drawing pipes on the lower surfaces of the moving components and width-adjusting components on the vehicle roof. This allows the water-absorbing components to absorb and remove the water that has accumulated locally on the moving components and width-adjusting components on the vehicle roof. This reduces or minimizes the problem of water droplets condensing on the moving components and width-adjusting components falling onto the already dried vehicle roof and causing secondary dampness or contamination, thereby further improving the vehicle washing and drying effect.

[0043] In summary, this invention has the advantages of simple structure, easy implementation, small equipment footprint, energy saving and environmental protection, clean car washing and minimal damage to vehicles. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] Example 1

[0056] like Figure 1-2 As shown, the present invention provides a fully automatic water-saving car wash machine, including a frame 1;

[0057] Mobile component 2, which is mounted on frame 1;

[0058] The spray assembly 3, which is used to spray steam at an angle to wash the upper surface of the vehicle, is disposed on the movable assembly 2;

[0059] The washing assembly 4 is located below the spray assembly 3, which uses the spray assembly 3 to spray water to wash the lower surface of the vehicle.

[0060] Furthermore, the moving component 2 includes a longitudinal drive rod 21 arranged along the Y-axis, a first slider 22, a transverse drive rod 23 arranged along the X-axis, and a second slider 24; the longitudinal drive rod 21 is connected to the frame 1; the first slider 22 is slidably disposed on the longitudinal drive rod 21, and the transverse drive rod 23 is rotatably disposed on the first slider 22; the second slider 24 is slidably disposed on the transverse drive rod 23; the transverse drive rod 23 is driven to rotate by a first motor 231, and the longitudinal drive rod 21 is driven to rotate by a second motor 211.

[0061] Furthermore, a first lifting member 25 is provided below the second slider 24. The first lifting member 25 is a cylinder, a hydraulic cylinder, or an electric telescopic rod; the spraying assembly 3 is disposed on the first lifting member 25.

[0062] Furthermore, such as Figure 2-3As shown, the spray assembly 3 includes an inverted L-shaped contour tube 31, on which a plurality of obliquely arranged oblique holes 311 are provided, and nozzles are arranged on the oblique holes 311. By cleaning the vehicle surface at an angle, the dirt on the vehicle surface is cleaned to one side to avoid contaminating the cleaned area. The oblique cleaning improves the impact effect on the dirt on the vehicle surface.

[0063] Furthermore, the spray assembly 3 is connected to the first lifting component 25 via a connecting pipe 32. An air slip ring 33 is provided on the connecting pipe 32. The air slip ring 33 is rotatably connected to the connecting pipe 32, and water or steam is introduced into the contour tube 31 through the air slip ring 33 and the connecting pipe 32.

[0064] It should be noted that, as Figure 1-2 As shown in Figure 7, the vehicle position and the position and working status of the spray assembly 3 and the washing assembly 4 relative to the vehicle are detected by sensors installed on the frame 1, and the computer 11 provides fully automatic intelligent control, causing the moving assembly 2 to drive the spray assembly 3 to move along the contour of the vehicle. The first lifting component 25 adjusts the height of the spray assembly 3. The washing assembly 4 moves synchronously with the spray assembly 3. Generally, the dirt on the upper part of the vehicle is less than that on the lower part and is easier to clean. Therefore, the upper part of the vehicle is washed by spraying steam or a mixture of steam and water through the spray assembly 3 to reduce water consumption, while simultaneously sterilizing and disinfecting the vehicle surface, reducing the spread of harmful bacteria, and reducing damage to the upper surface of the vehicle, thus extending the service life of the vehicle surface coating. The washing assembly 4, located below the spray assembly 3, uses the water flow sprayed by the spray assembly 3 to clean the dirtier lower part of the vehicle, which can further reduce the water consumption for vehicle cleaning.

[0065] like Figure 3-4 As shown, it also includes a recovery component 5 for recovering the water flow generated by the spraying component 3 that is free of oil or contains a small amount of oil, the recovery component 5 being disposed between the spraying component 3 and the scrubbing component 4.

[0066] It should be noted that when the steam or steam-water mixture ejected by the spray component 3 falls, it flows to the recovery component 5, which partially recovers and reuses the water. The upper part of the recovery component 5 is positioned above the bottom of the door of a conventional vehicle. Since the upper surface of the vehicle's outer shell 12 is not covered with engine oil or has only a small amount of oil, the water can be recovered and, after simple sedimentation and filtration, can be used for the first pre-washing of vehicles with a lot of surface dirt without the need to remove the oil from the collected water, which contains little or no engine oil. By classifying and collecting the car wash water, water resources can be reused and water can be saved. Furthermore, due to the strict control of sewage discharge and treatment in various regions, the cost of cleaning and treating the recovered water can be reduced by setting up the recovery component 5.

[0067] Furthermore, such as Figure 3-4 As shown, the recycling component 5 includes:

[0068] A recycling tray 51 is disposed between the spray assembly 3 and the scrubbing assembly 4;

[0069] The first elastic element 52 is disposed on one end of the recycling tray 51 and follows the recycling tray 51 to approach the vehicle and abuts against the vehicle surface.

[0070] An elastic waterproof cloth 53 is laid on a recycling tray 51, and one end of the elastic waterproof cloth 53 is connected to the end of the first elastic member 52 and moves with the first elastic member 52 and approaches the vehicle surface.

[0071] Furthermore, the recovery disc 51 is connected to the lower end of the contour tube 31; the spray assembly 3 moves and drives the recovery disc 51 to move, the recovery disc 51 located on one side of the spray assembly 3 is longer than the other side of the spray assembly 3, and a second recovery tube 54 is provided on the recovery disc 51; bristles 55 are provided on the side of the recovery disc 51 near the first elastic member 52; the elastic waterproof cloth 53 is made of rubber or other non-metallic elastic materials.

[0072] It is necessary to note that, since the spray assembly 3 sprays water at an angle onto the vehicle surface, the longer recovery disc 51 is located on the side of the spray assembly 3 to achieve better water recovery from the spray. When the spray assembly 3 is close to the vehicle but maintains a certain distance from it, the first elastic element 52 abuts against the vehicle surface, and the first elastic element 52 can automatically extend and retract at the end of the recovery disc 51 to adapt to the vehicle surface. The first elastic element 52 is made of a non-metallic soft material; furthermore, the first elastic element 52 is made of rubber. Rubber material can reduce or avoid scratches on the vehicle surface. Also, being located near the vehicle wheels, the softer first elastic element 52 is easier to disengage if it gets stuck on the vehicle surface during movement. The side wall of the recovery disc 51 is designed with... A hole is provided for installing the first elastic element 52, and a spring is installed in the hole. The elastic waterproof cloth 53 is close to the vehicle surface. When the first elastic element 52 abuts against the vehicle surface, there is a gap between the elastic waterproof cloth 53 and the vehicle surface. The gap is between 2 mm and 2 cm. Furthermore, the gap is 2 mm, 5 mm, 8 mm, 1 cm, or 2 cm. This is to prevent the elastic waterproof cloth 53 from sticking to the vehicle surface. On the one hand, it reduces the friction between the elastic waterproof cloth 53 and the vehicle surface, thereby reducing the wear of the elastic waterproof cloth 53 and the vehicle surface. On the other hand, it allows a small amount of water to flow directly down the vehicle surface to rinse the vehicle surface and remove some dirt. It also makes it easier for the washing assembly 4 to use the flowing water to clean the lower part of the vehicle without having to supply water to the washing assembly 4.

[0073] Furthermore, such as Figure 2 , 5As shown, a drying assembly 6 for drying the washed vehicle surface is provided on one side of the spraying assembly 3; the drying assembly 6 includes:

[0074] Extraction pipe 61; Injection pipe 62;

[0075] Multiple absorbent strips 63 are mounted on the movable assembly 2 via extraction pipes 61 and spray pipes 62. The extraction pipes 61, used to extract moisture from the inside of the absorbent strips 63, extend into the inside of the absorbent strips 63. The spray pipes 62, used to blow air onto the vehicle from the end of the absorbent strips 63 for drying, extend into the absorbent strips 63 and reach the end of the absorbent strips 63.

[0076] Furthermore, the extraction tube 61, the spray tube 62, and the water-absorbing strip 63 are all made of soft materials that are easy to adhere to the vehicle surface. The water-absorbing strip 63 is made of cotton or absorbent sponge. The surface of the section of the extraction tube 61 that extends into the water-absorbing strip 63 has multiple holes evenly distributed to extract water from the water-absorbing strip 63 and keep it absorbent for a long time. The diameter of the extraction tube 61 is less than or equal to one centimeter so that it can smoothly extract water from the water-absorbing strip 63. The spray tube 62 has multiple holes near the end of the water-absorbing strip 63, and these holes extend out of the water-absorbing strip 63 to allow the spray tube 62 to blow air and dry the vehicle surface.

[0077] In addition, by controlling the speed and volume of the jet spray from the spray pipe 62, the end of the water-absorbing strip 63 can be raised without contacting the vehicle surface. This achieves continuous drying of water stains on the vehicle surface after wiping, and the end of the water-absorbing strip 63 has a certain guiding effect on the airflow sprayed from the spray pipe 62, so that more airflow is blown onto the vehicle surface. At the same time, the cooperation between the spray pipe 62 and the water-absorbing strip 63 allows the water-absorbing strip 63 to move or shake when it comes into contact with the vehicle surface, enabling the water-absorbing strip 63 to wipe the vehicle surface better.

[0078] Furthermore, the angle between the absorbent strip 63 located on the edge side and the absorbent strip 63 located in the middle is between 70° and 120°.

[0079] Furthermore, since water stains on the sides of the vehicle need to be wiped off, the water-absorbing strips 63, which are set obliquely or vertically on the edges, increase the contact area between the water-absorbing strips 63 and the sides of the vehicle, thereby improving the wiping effect.

[0080] Furthermore, such as Figure 2 , 5 As shown, the drying assembly 6 further includes a width adjustment assembly 64 for adjusting the total width of all absorbent strips 63; the width adjustment assembly 64 includes:

[0081] A bidirectional drive rod 641 with a forward spiral groove at one end and a reverse spiral groove at the other end;

[0082] Multiple sliding members 642 are spaced apart on the bidirectional drive rod 641, and the sliding members 642 at both ends are engaged with the spiral grooves on the bidirectional drive rod 641, and one side of the sliding member 642 is in sliding contact with the moving component 2.

[0083] A second elastic element 643 is provided between adjacent sliding elements 642;

[0084] The extraction pipe 61 and the spray pipe 62 on the same water absorption strip 63 are connected to the corresponding sliding member 642.

[0085] Furthermore, the bidirectional drive rod 641 is driven to rotate by the third motor 6411; the rotating bidirectional drive rod 641 drives the two sliding parts 642 at both ends to slide closer or further away, thereby adjusting the width of the row of absorbent strips 63, so that the absorbent strips 63 on both sides are close together and piled up on the side of the vehicle to better dry the water stains on the side of the vehicle, and can also adapt to the wiping of vehicles of different widths.

[0086] Example 2

[0087] like Figure 1-7 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Figure 2 , 5 As shown, a winding assembly 65 is also provided on the side of the drying assembly 6;

[0088] The take-up assembly 65 includes a take-up roller 651 and a pull rope 652; the other end of the pull rope 652, which is connected to the end of the absorbent strip 63, is slidably disposed along the axial direction of the take-up roller 651; the take-up roller 651 takes up the absorbent strip 63 to achieve the take-up of the absorbent strip 63 or to adjust the spray angle of the spray pipe 62 at the end of the absorbent strip 63.

[0089] Furthermore, the take-up roller 651 is driven to rotate by the fourth motor 653; a groove is provided on the lower side of the take-up roller 651, and the pull rope 652 is slidably arranged in the groove through the second slider 654; along the length of the spray pipe 62 and away from the end of the absorbent strip 63, and near the hole provided on the spray pipe 62, a weight 631 is provided on the surface of the absorbent strip 63. The weight 631 is made of non-metallic material, and the weight 631 is provided to make the absorbent strip 63 on the vehicle surface adhere more closely to the vehicle surface and absorb water stains on the vehicle surface; firstly, the take-up assembly 65 pulls the pull rope 652 by rotating the take-up roller 651, which can adjust The height of the absorbent strip 63 from the ground is as follows: First, the absorbent strip 63, the extraction pipe 61, and the spray pipe 62 are wound up by the winding assembly 65 to avoid affecting the operation of the spray assembly 3 and the washing assembly 4. Second, the winding assembly 65 can adjust the distance between the end of the absorbent strip 63 and the vehicle surface, as well as the spray angle, so that the spray pipe 62 can blow air to dry the vehicle surface at a better spray angle. Third, the winding assembly 65 can wring the absorbent strip 63 to a certain extent. When the absorbent strip 63 is in a loose state after winding, it can be dried by the spray pipe 62.

[0090] Furthermore, such as Figure 6 As shown, the lower surfaces of the moving component 2 and the width adjusting component 64 located above are both provided with water-absorbing components 66, and a water-drawing pipe 67 is provided inside the water-absorbing component 66. The water-drawing pipe 67 is connected to the extraction pipe 61.

[0091] Furthermore, the water-absorbing component 66 is a water-absorbing sponge. By arranging the water-absorbing component 66 and the water-drawing pipe 67 that extracts water from the water-absorbing component 66 on the lower surface of the moving component 2 and the width adjustment component 64 on the vehicle top, the water-absorbing component 66 can continuously absorb and remove the water locally accumulated on the moving component 2 and the width adjustment component 64 on the vehicle top. This reduces or minimizes the problem of water droplets condensed on the moving component 2 and the width adjustment component 64 falling onto the already dried vehicle top and causing secondary dampness or pollution, thereby further improving the vehicle washing and drying effect.

[0092] Furthermore, such as Figure 4 As shown, the washing assembly 4 includes:

[0093] A washing drive unit 41 is arranged below the recycling assembly 5;

[0094] Mounting housing 42; the mounting housing 42 is sleeved on the outside of the washing drive component 41;

[0095] Car wash brush 43, the car wash brush 43 being evenly distributed on the mounting housing 42;

[0096] Furthermore, the mounting housing 42 is provided with a recessed groove. The washing drive component 41 is a fifth motor, and the car wash brush 43 is a foam brush. The foam brush does not absorb water or stick to stones, and can provide good protection for the vehicle surface when cleaning. The foam brush is folded in the middle and inserted into the groove, and a protrusion 44 is inserted into the foam brush in the groove to fix the foam brush on the mounting housing 42, thereby facilitating the installation, removal and replacement of the car wash brush 43. The mounting housing 42 is fitted over the outer surface of the washing drive component 41, which can provide a certain degree of waterproof protection for the washing drive component 41. Furthermore, the vibration of the washing component 4 during washing drives the spray component 3 to vibrate and spray, promoting the cleaning effect of the spray component 3.

[0097] Furthermore, such as Figure 7 As shown, a fully automatic water-saving car wash machine also includes a housing 12 disposed outside the frame 1 and covering the frame 1, and the housing 12 is provided with a plurality of first recycling pipes 13.

[0098] Furthermore, the outer shell 12 is provided with a sensor door 15, which automatically opens when a person or vehicle enters or exits; a drainage ditch 14 is provided below the outer shell 12, which is buried underground to achieve sewage discharge and treatment, reducing the impact of sewage on the external environment of the car wash.

[0099] It should be further explained that by setting an outer shell 12 and a first recycling pipe 13 outside the frame 1, on the one hand, the outer shell 12 can prevent the vehicle from being directly exposed to sunlight during washing. Water droplets on the vehicle surface will form a convex lens, causing local sunlight to concentrate and shine on the vehicle surface. Therefore, the use of the outer shell 12 extends the service life of the vehicle surface coating. On the other hand, the vehicle surface is cleaned in the form of steam during car washing. A large amount of steam is covered by the outer shell 12 to prevent steam from overflowing and affecting other vehicles and staff in the car wash. At the same time, a large amount of steam is retained and extracted and recycled through the first recycling pipe 13, which can realize the direct recycling of water resources. This reduces or avoids the trouble of filtering and removing impurities from the water resources during recycling, and lowers the cost of water resource recycling.

[0100] Work steps:

[0101] Step 1: The vehicle drives into the outer shell 12 and stops;

[0102] Step 2: The moving component 2 drives the spraying component 3 and the washing component 4 close to the vehicle surface and moves along the contours of the vehicle to clean the vehicle's sides, top, and bottom.

[0103] Step 3: While Step 2 is being performed, a portion of the water sprayed by the spray assembly 3 falls into the recovery assembly 5 and is recovered. This portion of water contains little or no engine oil, so it can be used to clean the bottom of the vehicle without removing oil during the cleaning process. The recovery assembly 5 adheres to the surface of the vehicle and moves with the spray assembly 3.

[0104] Step four: After the vehicle is washed, the moving component 2 moves the drying component 6 and the winding component 65 to one end of the vehicle. The winding component 65 lowers the absorbent strip 63, and the width adjustment component 64 adjusts the overall width of the absorbent strip 63 so that the absorbent strips 63 on both sides are attached to the sides of the vehicle. The moving component 2 moves the winding component 65 and the drying component 6 along the length of the vehicle, causing the absorbent strip 63 to drag on the surface of the vehicle. The first end of the absorbent strip 63 wipes the water stains on the surface of the vehicle, and the spray pipe 62 at the end of the absorbent strip 63 blows air to dry the surface of the vehicle, achieving the goal of drying the water stains on the surface of the vehicle in one go. The extraction pipe 61 extracts the water stains in the absorbent strip 63 for recycling.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
