Description

Technical Field

[0001] This invention relates to the field of vehicle washing technology, specifically to an intelligent liquid-dispensing washing device and washing method. Background Technology

[0002] Currently, car wash systems are key devices for safe driving and exterior maintenance. Their core function is to use sprayed washer fluid in conjunction with windshield wipers to remove dirt and grime from components such as the windshield, ensuring clear visibility for the driver and protecting the vehicle's appearance. The washer fluid reservoir is typically located in the engine compartment, requiring frequent refilling, with the fluid level kept between the minimum and maximum marks each time, making refilling somewhat inconvenient.

[0003] In related technologies, to solve the problem of inconvenient water replenishment, a car wash system has emerged on the market, such as... Figure 1 As shown, the car wash system includes a water storage device a located inside the vehicle cabin and having a water storage chamber. The vehicle cabin is either the front or rear cabin, and the water storage device a is a washing jug. A water replenishment device b is also provided at the upper end of the water storage device a. The water replenishment device b includes a water inlet b1 located on the vehicle body, with one end communicating with the upper surface of the vehicle body. The other end of the water inlet b1 is connected to the water storage chamber of the water storage device a via a pipe b2.

[0004] However, traditional car wash systems use rainwater directly for cleaning, which is not effective enough. The water inlet is located on the car body, and rainwater can easily bring in dust and waste during vehicle use, clogging the water replenishment device b or the water storage device a, increasing maintenance costs.

The controller is connected to the movable plug device, the wipers, and two pumps. The controller is used to mix the detergent in the mixing chamber, to control the movable plug device to open the water inlet to collect rainwater after cleaning the glass and when the wipers are not activated, and to control the output of clean water or detergent water when the wipers are activated.

[0007] In conjunction with the first aspect, in one embodiment, the first water tank is equipped with a first water level detector; a pressure sensor is provided on the back of the movable block device; The controller signal is connected to the first water level detector and the pressure sensor; When the pressure sensor reading is greater than the set pressure threshold for a period of time, the controller detects that the windshield wipers are not activated, and the first water level detector detects that the water level in the first water tank is lower than the first set water level, the controller controls the movable block device to open the water inlet.

The sleeve contains a spring and a locking mechanism. The stopping structure is used to stop the cylindrical tube structure at a position where the axis of the sleeve coincides with the axis of the water inlet. The extension end of the linear control motor is equipped with an inclined pad. When the cylindrical tube structure is stopped in the stopping structure, when the top of the inclined pad is below the sleeve, the inclined pad compresses the spring and holds the locking mechanism to extend along the sleeve, closing the water inlet. When the bottom of the inclined pad is below the sleeve, the inclined pad naturally extends the spring and drives the locking mechanism to retract along the sleeve, opening the water inlet.

[0013] Secondly, embodiments of this application provide a washing method based on the above-described washing device, wherein the washing device further includes a stain camera connected to a controller; the washing method includes the following steps: When the wipers are activated, the controller determines whether there are stains larger than a set area on the outer surface of the glass based on the image sampling results from the stain camera.

[0016] The beneficial effects of the technical solutions provided in this application include at least the following: 1. The washing device and method of this application mainly have three functions: ① when it rains and the wipers are not activated, the movable block device opens the water inlet to collect rainwater; ② the detergent is mixed; ③ when the wipers are activated, clean water and detergent water are output as needed. It can fully recycle rainwater, and the water inlet collects rainwater each time after cleaning the glass, effectively preventing dust and waste from being carried into the first water tank. A detergent box is added to allow for the proportional addition of detergent, improving the washing effect of the device.

[0017] 2. The washing device and washing method of this application can realize intelligent control. When the pressure sensor is greater than the set pressure threshold and continues for a period of time, it indicates that it is raining. When the controller learns that the wiper is not activated, it means that the water inlet can be opened. When the first water level detector learns that the liquid level of the first water tank is lower than the first set liquid level, it means that the water volume is insufficient and water needs to be added. At this time, the controller can automatically control the movable block device to open the water inlet and collect rainwater, which is intelligent and efficient.

[0018] 3. The washing device of this application can realize intelligent independent water replenishment of the clear water chamber and the mixing chamber through the controller, two first electric control valves, the second water level detector and the third water level detector, making full use of rainy weather, improving the intelligent performance of the washing device, and greatly extending the single use time of the washing device (i.e., the time interval between two manual water replenishments is greatly extended).

[0019] 4. In the washing device of this application, when the water level of the third water level detector is lower than the third set liquid level, the first water storage tank replenishes water to the mixing chamber until the water level of the third water level detector reaches the set sufficient water level threshold. The detergent tank pumps a fixed amount of detergent into the mixing chamber through the second pump to form detergent water with basically consistent concentration. The washing device of this application intelligently maintains detergent water with sufficient concentration and sufficient liquid level, resulting in good washing and cleaning effect.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0023] like Figure 2 , Figure 3 and Figure 4 The present application discloses an embodiment of an intelligent liquid-dispensing washing device, which includes a water inlet, a movable block device 1, a first water reservoir 2, a second water reservoir 4, a detergent reservoir 9, and a controller.

[0024] The water intake is located at the bottom of the windshield.

[0025] The movable blocking device 1 is movably installed inside the windshield. The movable blocking device 1 is used to block the water intake in the normal state, and also to open the water intake to collect rainwater when it rains and the wipers are not turned on.

[0026] The first water tank 2 is connected to the open water inlet via a water inlet pipe to collect rainwater.

[0027] The second water reservoir 4 is connected to the first water reservoir 2. When needed, the first water reservoir 2 replenishes the second water reservoir 4. The second water reservoir 4 is divided into a clear water chamber 41 and a mixing chamber 42 by a partition plate. Specifically, the power source for the first water reservoir 2 to replenish the second water reservoir 4 is that the height of the outlet of the first water reservoir 2 is greater than the maximum liquid level of the second water reservoir 4, so water can be replenished naturally without any power.

[0028] The detergent pitcher 9 connects to the mixing chamber 42 and supplies detergent to it. The detergent pitcher 9 is fed into the mixing chamber 42 via the second pump 8. The clean water chamber 41 outputs clean water through the first pump 5 and the outlet pipe 12, while the mixing chamber 42 outputs detergent water through the first pump 5 and the outlet pipe 12.

[0029] The controller signal connects the movable block device 1, the wipers, and two pumps. The controller is used to control the movable block device 1 to open the water inlet to collect rainwater when the wipers are not activated, and also to control the first pump 5 to output clean water and detergent water when the wipers are activated.

[0030] Specifically, before opening the water inlet to collect rainwater by opening the movable block device 1, the wiper is used to clean the area for a certain period of time.

[0031] The washing device of this application has three main functions: ① when it rains and the wipers are not activated, the movable block device 1 opens the water inlet to collect rainwater; ② the detergent is mixed; ③ when the wipers are activated, clean water and detergent water are output as needed. It can fully recycle rainwater, and the water inlet collects rainwater each time after cleaning the glass, effectively preventing dust and waste from being brought into the first water tank 2. A detergent box is added to add detergent in proportion, which improves the washing effect of the washing device. Both clean water and detergent water can be used to clean the wipers. When the wipers are very dirty, detergent water is used, which greatly increases the cleaning ability. The washing device of this application realizes car washing and automation, improves the user experience, makes the product more user-friendly, and increases the convenience of operation.

[0032] Furthermore, in one embodiment, the first water tank 2 is equipped with a first water level detector 7.

[0033] A pressure sensor 105 is installed on the back of the movable block device 1. When the pressure sensor 105 exceeds a set pressure threshold and remains so for a period of time, the controller determines that it is raining. Specifically, rain will impact the movable block device 1, causing a certain pressure to be sensed on the back of the movable block device 1.

[0034] The controller 10 is connected to the first water level detector and the pressure sensor 105.

[0035] When the pressure sensor 105 exceeds the set pressure threshold for a period of time, the controller learns that the wipers are not activated, and the first water level detector 7 learns that the water level in the first water tank 2 is lower than the first set water level, the controller 10 controls the movable block device 1 to open the water inlet to collect rainwater.

[0036] Specifically, before opening the water inlet, use the wipers to clean the glass for a set period of time; there is no need to spray water or detergent.

[0037] The washing device of this application can realize intelligent control. When the pressure sensor 105 is greater than the set pressure threshold and continues for a period of time, it indicates that it is raining. The controller knows that the wiper is not activated, indicating that the water inlet can be opened. When the first water level detector 7 knows that the liquid level of the first water tank 2 is lower than the first set liquid level, it indicates that the water volume is insufficient and water needs to be added. At this time, the controller can automatically control the movable block device 1 to open the water inlet and collect rainwater, which is intelligent and efficient.

[0038] Furthermore, in one embodiment, a main pipe is provided between the first water tank 2 and the second water tank 4, followed by two branch pipes; each branch pipe is equipped with a first electrically controlled valve 3, and the two branch pipes are respectively connected to the clear water chamber 41 and the mixing chamber 42. The clear water chamber 41 is equipped with a second water level detector 13, and the mixing chamber 42 is equipped with a third water level detector 14. The controller 10 is signal-connected to the two first electrically controlled valves 3, the second water level detector 13, and the third water level detector 14.

[0039] When the liquid level of the second water level detector 13 is lower than the second set liquid level, the corresponding first electric control valve 3 is opened, and the first water storage tank 2 replenishes water to the clear water chamber 41.

[0040] When the liquid level of the third water level detector 14 is lower than the third set liquid level, the corresponding first electric control valve 3 is opened, and the first water storage tank 2 replenishes water to the mixing chamber 42.

[0041] Specifically, during the water replenishment process of the clear water chamber 41 and the mixing chamber 42, if the liquid level of the first water reservoir 2 is too low, the controller will issue a prompt and the first water reservoir 2 will be manually replenished.

[0042] The washing device of this application can achieve intelligent independent water replenishment of the clear water chamber 41 and the mixing chamber 42 through the controller 10, two first electric control valves 3, the second water level detector 13 and the third water level detector 14, making full use of rainy weather, improving the intelligent performance of the washing device, and greatly extending the single use time of the washing device (i.e., the time interval between two manual water replenishments is greatly extended).

[0043] Preferably, the clear water chamber 41 and the mixing chamber 42 are each provided with a water outlet, and the two water outlets output water to the outside through two water outlet pipes.

[0044] like Figure 4 Furthermore, in one embodiment, the second water tank 4 has a water outlet at a corresponding position on the partition plate, and an internal movable block 46 is provided inside the water outlet. Specifically, the horizontal plane at the middle of the thickness direction of the partition plate divides the water outlet into two equal halves. The internal movable block 46 is driven by a waterproof linear motor, which is connected to the controller 10. Water flows out of the water outlet through a water outlet pipe 12.

[0045] When the internal movable block 46 blocks only half of the outlet of the clear water chamber 41, cleaning agent water is output; when the internal movable block 46 blocks only half of the outlet of the mixing chamber 42, clear water is output.

[0046] The washing device of this application has a second water tank 4 with two inlets and one outlet. When the internal movable block 46 blocks only half of the outlet of the clean water chamber 41, it outputs cleaning agent water; when the internal movable block 46 blocks only half of the outlet of the mixing chamber 42, it outputs clean water. The internal movable block 46 is cleverly designed.

[0047] Furthermore, in one embodiment, the outlet of the first water reservoir 2 is higher than the highest liquid level of the second water reservoir 4, allowing for natural water replenishment without the need for power.

[0048] The mixing chamber 42 of the second water storage tank 4 is equipped with a stirring device 43.

[0049] When the water level of the third water level detector 14 reaches the set sufficient water level threshold, the detergent jug 9 pumps a measured amount of detergent into the mixing chamber 42 through the second pump 8. At the same time, the controller 10 controls the stirring device 43 to rotate, forming a uniform detergent water.

[0050] Specifically, the third set liquid level is set to a very small value. When the water level of the third water level detector 14 is lower than the third set liquid level, the first water storage tank 2 replenishes water to the mixing chamber 42 until the water level of the third water level detector 14 reaches the set sufficient water level threshold. Then, the cleaning agent tank 9 pumps a fixed amount of cleaning agent into the mixing chamber 42 through the second pump 8 to form cleaning agent water with a basically consistent concentration.

[0051] In the washing device of this application, when the water level of the third water level detector 14 is lower than the third set liquid level, the first water storage tank 2 replenishes water to the mixing chamber 42 until the water level of the third water level detector 14 reaches the set sufficient water level threshold. The detergent tank 9 pumps a fixed amount of detergent into the mixing chamber 42 through the second pump 8 to form detergent water with basically consistent concentration. The washing device of this application intelligently maintains detergent water with sufficient concentration and sufficient liquid level, resulting in good washing and cleaning effect.

[0052] Furthermore, in one embodiment, the second water tank 4 outputs clean water or cleaning agent water through the water outlet pipe 12, which branches and leads to the front windshield and the rear windshield respectively.

[0053] A second electrically controlled valve 6 is installed at the fork of the water outlet pipe 12. The second electrically controlled valve 6 is used to control the flow direction of clean water or cleaning agent water. It can flow to the windshield alone, to the rear windshield alone, or to both the windshield and the rear windshield at the same time.

[0054] The first pump 5 is located between the second electrically controlled valve 6 and the second water reservoir 4, providing power for supplying clean water or detergent water. The second pump 8 is located between the second water reservoir 4 and the detergent reservoir 9.

[0055] Furthermore, in one embodiment, the washing device also includes a stain camera connected to the controller 10. Before the wipers are activated, the controller 10 determines whether there are stains larger than a set area on the outer surface of the glass based on the image sampling results from the stain camera. If no stains are found, the controller 10 outputs clean water from the clean water chamber 41 via the first pump 5; if stains are found, the controller 10 outputs cleaning agent water from the mixing chamber 42 via the first pump 5. The stains include dry stains (such as dried and solidified dust, sand, bird droppings, etc.) and wet stains (sewage and oil stains, etc.).

[0056] like Figure 5 and Figure 6 Furthermore, in one embodiment, the washing device also includes a housing structure and a stopping structure. The movable blocking device 1 includes a linear control motor 101, a circular tube structure, a sleeve 102, a locking mechanism 103, and an inclined pad 104.

[0057] The housing structure is used to seal and cover all structures of the movable block device 1 except for the linear control motor 101. The housing structure is connected to the end of the water inlet pipe. The housing structure and the movable block device 1 work together to ensure both the opening and closing of the water inlet and the guidance of rainwater to the water inlet pipe and into the first water storage tank 2. Specifically, the stop structure is also sealed and covered by the housing structure.

[0058] A sleeve 102 is fixed to the inner wall of the cylindrical tube structure via a rib plate at the axial position. A spring and a locking mechanism 103 are installed inside the sleeve 102. Inside the sleeve 102, one end of the spring is fixed to the top inner wall of the sleeve 102, the locking mechanism 103 passes through the spring, and the other end of the spring is fixed to the bottom end of the locking mechanism 103.

[0059] An inclined pad 104 is provided at the telescopic end of the linear control motor 101. The length of the inclined pad 104 is less than the diameter of the circular tube structure and is basically equal to the radius of the circular tube structure.

[0060] The stopping structure is used to stop the circular tube structure at the position where the axis of the sleeve 102 coincides with the axis of the water inlet. When the circular tube structure enters or exits the stopping structure, the inclined pad 104 is required to support the circular tube structure to move before it can enter or exit the stopping structure. The circular tube structure remains stationary relative to the stopping structure, while the inclined pad 104 moves inside the circular tube structure.

[0061] When the circular tube structure is stopped in the stop position and the top of the inclined pad 104 is below the sleeve 102, the inclined pad 104 compresses the spring and holds the locking mechanism 103 to extend along the sleeve 102, thus closing the water inlet.

[0062] When the circular tube structure is stopped in the stop position and the bottom of the inclined pad 104 is below the sleeve 102, the inclined pad 104 causes the spring to extend naturally and drives the locking mechanism 103 to retract along the sleeve 102, opening the water inlet.

[0063] When the device is stopped, the linear control motor 101 drives the inclined pad 104 to move relative to the circular tube structure inside the circular tube structure; when the device is not stopped, the linear control motor 101 drives the inclined pad 104 and the circular tube structure to move synchronously.

[0064] Specifically, the movable blocking device 1 is inclined and parallel to the inside of the windshield, with the locking structure facing upwards.

[0065] Specifically, such as Figure 7 As shown, the working principle of the movable blocking device 1 is as follows: The inclined pad 104 is controlled to move left and right by a linear control motor 101. When the pressure sensor 105 on the back of the inclined pad 104 senses pressure and the user has not started the windshield wipers, it is assumed that it is raining and water can be drawn in. At this time, the movable block device 1 is located in... Figure 6 In the initial normal state shown (i.e., the locking mechanism 103 closes the water inlet), the spring is in a compressed state, and the circular tube structure is stopped in the stop position.

[0066] The linear control motor 101 controls the lever to move in the opening direction. Figure 6 When the spring moves to the right (towards the opening direction), it extends to its natural state, causing the locking mechanism 103 to move downwards along the sleeve 102, opening the water inlet. During this process, the circular tube structure stops, and the inclined pad 104 moves within the circular tube structure.

[0067] As it continues to move to the right, the right end of the inclined pad 104 resists the circular tube structure, causing the entire circular tube structure to move to the right. The circular tube structure disengages from the stopping structure, completely clearing the water inlet.

[0068] When water collection is complete (the first water level detector 7 of the first water tank 2 detects that the rainwater collection is full, or the rain has stopped), the linear control motor 101 controls the movement in the blocking direction. First, the inclined pad 104 and the circular tube structure move to the left synchronously until the circular tube structure stops at the stop position. The circular tube structure does not move (the locking mechanism 103 is aligned with the water inlet). The inclined pad 104 continues to move to the left, while the circular tube structure does not move. The inclined pad 104 moves to the left relative to the circular tube structure. The inclined pad 104 raises the locking mechanism 103, the spring is compressed, and the locking structure extends to block the water inlet to prevent debris from entering.

[0069] In other embodiments, the movable blocking device 1 may also employ an electrically driven locking mechanism. Similarly, the washing device also includes a housing structure and a stopping structure, and the movable blocking device 1 includes a linear control motor 101 and a circular tube structure. The electrically driven locking mechanism is located at the center of the circular tube structure; when stopped, the controller controls the extension and retraction of the electrically driven locking mechanism via an electrical signal.

[0070] Specifically, Figure 5 The image shows a partially enlarged schematic diagram of the movable blocking device 1 located on the inner side of the lower part of the windshield.

[0071] This application features a cleverly designed movable block device 1 that can only open and close the water inlet without affecting rainwater collection.

[0072] Secondly, this application discloses a washing method based on the above-mentioned washing device, the washing device further comprising a stain camera connected to the controller 10; The washing method includes the following steps: Before the wipers are activated, the controller 10 determines whether there are dry stains larger than a set volume on the outer surface of the glass based on the image sampling results of the stain camera. If there are no stains, the controller 10 outputs clean water from the clean water chamber 41 through the first pump 5; if there are stains, the controller 10 outputs cleaning agent water from the mixing chamber 42 through the first pump 5.

[0073] Specifically, wet stains (such as oil stains) are generally easy to clean and can be washed with water. However, dry stains larger than the set volume are more difficult to clean and require the use of detergent and water.

[0074] The washing method described in this application determines whether to wash with clean water or detergent water based on the image sampling results from the stain camera during actual washing, which, combined with practical considerations, results in strong cleaning ability.

[0075] Regarding the washing method, further, in one embodiment, the mixing chamber 42 is equipped with a third water level detector 14, and the mixing chamber 42 is equipped with a stirring device 43. Both the third water level detector 14 and the stirring device 43 are connected to a controller. The washing method involves adding detergent to the mixing chamber 42, including: When the water level of the third water level detector 14 is lower than the third set liquid level, the first water storage tank 2 replenishes water to the mixing chamber 42 until the water level of the third water level detector 14 reaches the set sufficient water level threshold. The cleaning agent tank 9 pumps a measured amount of cleaning agent into the mixing chamber 42 through the second pump 8. The controller 10 controls the stirring device 43 to rotate, forming a uniform cleaning agent water.

[0076] like Figure 7As shown, regarding the washing method, in one embodiment, the washing device further includes a housing structure and a stopping structure. The movable blocking device 1 includes a linear control motor 101, a circular tube structure, a sleeve 102, a locking mechanism 103, and an inclined pad 104.

[0077] The housing structure is used to seal and cover all structures of the movable block device 1 except for the linear control motor 101. The housing structure is connected to the end of the water inlet pipe. The housing structure and the movable block device 1 work together to ensure both the opening and closing of the water inlet and the guidance of rainwater to the water inlet pipe and into the first water storage tank 2. Specifically, the stop structure is also sealed and covered by the housing structure.

[0078] A sleeve 102 is fixed to the inner wall of the cylindrical tube structure via a rib plate at the axial position. A spring and a locking mechanism 103 are installed inside the sleeve 102. Inside the sleeve 102, one end of the spring is fixed to the top inner wall of the sleeve 102, the locking mechanism 103 passes through the spring, and the other end of the spring is fixed to the bottom end of the locking mechanism 103.

[0079] An inclined pad 104 is provided at the telescopic end of the linear control motor 101. The length of the inclined pad 104 is less than the diameter of the circular tube structure and is basically equal to the radius of the circular tube structure.

[0080] The stopping structure is used to stop the circular tube structure at the position where the axis of the sleeve 102 coincides with the axis of the water inlet. When the circular tube structure enters or exits the stopping structure, the inclined pad 104 is required to support the circular tube structure to move before it can enter or exit the stopping structure. The circular tube structure remains stationary relative to the stopping structure, while the inclined pad 104 moves inside the circular tube structure.

[0081] When the circular tube structure is stopped in the stop position and the top of the inclined pad 104 is below the sleeve 102, the inclined pad 104 compresses the spring and holds the locking mechanism 103 to extend along the sleeve 102, thus closing the water inlet.

[0082] When the circular tube structure is stopped in the stop position and the bottom of the inclined pad 104 is below the sleeve 102, the inclined pad 104 causes the spring to extend naturally and drives the locking mechanism 103 to retract along the sleeve 102, opening the water inlet.

[0083] When the device is stopped, the linear control motor 101 drives the inclined pad 104 to move relative to the circular tube structure inside the circular tube structure; when the device is not stopped, the linear control motor 101 drives the inclined pad 104 and the circular tube structure to move synchronously.

[0084] Specifically, the movable blocking device 1 is inclined and parallel to the inside of the windshield, with the locking structure facing upwards.
