[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 7As shown, a convenient door-to-door car wash device includes a cleaning unit 1 for cleaning cars and a two-wheeled electric vehicle 2 (including a front end, a front seat, and a rear seat) for mounting the cleaning unit 1. The cleaning unit 1 is fixedly connected and installed on the rear seat of the electric vehicle 2. Since the two-wheeled electric vehicle 2 is a commonly used existing technology, this structural part will not be described in detail below.

[0024] This car wash equipment allows staff to provide door-to-door service via two-wheeled electric vehicles (2), eliminating the need for users to drive to the washing location, thus saving users both time and money and improving their experience. The equipment is also equipped with a cleaning device (1) to provide the necessary tools for the staff. The entire system is fully functional and provides high-quality service to users.

[0025] like Figures 1 to 6 As shown, the cleaning device 1 adopts an integrated structure stacked vertically, consisting of a first toolbox 12 and a second toolbox 11. The first toolbox 12 serves as the load-bearing and power core, while the second toolbox 11 is a top-covered storage and protection unit. Specifically, both are rotationally molded structures made of LLDPE or other plastic materials, which reduces the overall weight of the device and makes its production and use more convenient.

[0026] The first toolbox 11 includes at least two sets of water tank components 121 with internal water storage compartments 123 and connecting seats 122 for connecting the two sets of water tank components 121. In this embodiment, the connecting seat 122 is composed of a base plate 1221 and a surrounding plate 1222. The base plate 1221 is arranged horizontally, and its surface is provided with vertically penetrating mounting holes. The base plate 1221 is fixedly connected to the top surface of the rear seat bearing surface of the electric vehicle 2 through the mounting holes and bolts. The middle portion of one side of each of the two sets of water tank components 121 is respectively installed on the left and right sides of the base plate 1221. Figure 1 The two water tank components 121 are suspended on both sides of the load-bearing surface of the rear seat of the electric vehicle 2. When the two water tank components 121 are filled with water, they can maintain the balance of the electric vehicle 2 well.

[0027] At least two sets of enclosure panels 1222 are provided, which are respectively vertically arranged at the front and rear ends of the top surface of the bottom plate 1221, and the ends of the two sets of enclosure panels 1222 extend to the corresponding side walls of the two water tank components 121. The bottom plate 1221, the two enclosure panels 1222 and the two water tank components 121 together enclose and form a storage space 1223 that can accommodate the control element of the cleaning device 1.

[0028] In this embodiment Figure 5In the middle of the enclosure panel 1222, a through groove is provided, and a mounting plate (iron plate, much thinner than the enclosure panel 1222) is fixedly installed at this position. A power switch, operated by the operator and connected to the control element of the cleaning device 1, can be installed on the mounting plate. This arrangement makes it easier for the operator to operate and control the device.

[0029] In this embodiment, the second toolbox 11 is mounted on top of the first toolbox 11 and hinged to its top, allowing the second toolbox 11 to be flipped towards the front of the vehicle. This arrangement facilitates the addition / maintenance of the control elements of the cleaning assembly 13 within the storage space 1223. Simultaneously, to ensure the overall stability of the cleaning device 1, latches are provided on both sides of the first toolbox 11, and these latches are used to lock / unlock the second toolbox 11 and the first toolbox 11.

[0030] In order to better protect the control components, the top height of the enclosure 1222 is at the same level as the top height of the water tank 121, so as to ensure that the storage space 1223 is sealed when the second toolbox 11 is closed on the first toolbox 11.

[0031] like Figures 1 to 4 As shown, the second toolbox 11 includes a box body 121 and a box cover 112 hinged to the top of the box body 121. The box body 121 and the box cover 112 are connected and fixed by a snap fastener. The inside can hold cleaning mops, cleaning solutions, sponges and other cleaning tools.

[0032] like Figures 5 to 6 As shown, the first toolbox 11 water tank component 121 is a cuboid, and its front bottom extends towards the front side of the device to form a front extension 1121. The top height of the front extension 1121 is not higher than the top surface height of the water tank component 121, and its top length (20cm-25cm) is greater than its bottom length (15cm-20cm).

[0033] The top of the rear end of the water tank component 12 extends toward the rear side of the device to form a rear extension 1122. The bottom of the rear extension 1122 is recessed upward to form a recessed space, thereby constituting a hidden handle 1123. The hidden handle 1123 enhances the point of leverage when the equipment is stopped, making it easier to stop.

[0034] In this embodiment, extending the water tank component 121 of the first toolbox 11 forward and backward increases the water storage space of the water storage tank 123, making it easier to install more cleaning water. The front end structure of the water tank component 121 allows workers to get in and out of the vehicle more easily (reflected in the inclined design of the front end of the front extension 1121), and also provides better comfort (the comfort is reflected in the fact that the top height of the front extension 1121 is lower than the seat height).

[0035] like Figures 5 to 7 As shown, a water inlet 1124 is also provided on the outer wall of the rear extension 1122. The top of the water inlet 1124 slopes downward and backward toward the water tank 121, and its bottom slopes upward and backward toward the first toolbox 11, with the bottom slope angle greater than the top slope angle. A water inlet 1125 is provided at the top of the water inlet 1124, and a filter element 1126 for filtering impurities is provided inside the water inlet 1125. The water inlet 1124 designed as shown allows for more convenient and easier filling with water.

[0036] The bottom of the water tank 121 is provided with a downward protruding water outlet 1127. The water outlets 1127 of the two first toolboxes 11 can be connected by two branches of a three-way pipe. The main branch of the three-way pipe passes through the through groove and the mounting plate and is connected to the water inlet of the water pump 131. Its water outlet 1127 is connected to the water drum 132 (the structure and location of the water drum 132 will be described later).

[0037] The two first toolboxes 11 and water tank components 121 are quite heavy when filled with water, and the water in the tanks sways from side to side during the ride, which can affect the stability of the electric vehicle 2 and make it difficult for the operator to control the vehicle. The two first toolboxes 11 and water tank components 121 have the same structure and a symmetrical mounting structure that outputs water simultaneously through a three-way pipe, which can ensure the stability of the two-wheeled vehicle and prevent safety hazards caused by uneven weight distribution during the ride.

[0038] like Figure 3 and Figure 6As shown, the cleaning assembly includes a control element installed in the storage space 1223 and an operating element installed outside the first toolbox 11. The control element includes a controller 134 and a pressure reducer 135 installed in the storage space 1223; the operating element includes a water pump 131, a water drum 132, and a water gun 133 installed on the first toolbox 11 and connected in sequence. The controller 134 is electrically connected to the pressure reducer 135, the water pump 131, and the power switch. The inlet of the water pump 131 is connected to the main line of the three-way pipe, and its outlet 1127 is connected to the water drum 132. The base plate 1221 has a cable channel 1224 installed in the storage space, and the wiring of the controller 134 is electrically connected to the power supply of the electric vehicle 2 through the cable channel 1224.

[0039] In this embodiment, the water drum 132 can automatically retract into the water drum 132 after the pipeline is pulled out, and a limiter for stopping the retraction is provided on the pipeline; the water gun 133 adopts an adjustable spray mode water gun 133, which can perform multi-level adjustable cleaning.

[0040] like Figures 2 to 6 As shown, a tool mounting position 1225 is provided between the rear end of the base plate 1221 and the corresponding enclosure plate 1222. The water drum 132 is horizontally mounted on the tool mounting position 1225. This setting can avoid obscuring the license plate information of the electric vehicle 2 and can better identify the vehicle.

[0041] To allow staff to ride more comfortably, a tool mounting position 1225 is also provided between the front end of the base plate 1221 and the corresponding side panel 1222. This design provides staff with more seating space and improves riding comfort.

[0042] like Figure 1 , Figure 4 and Figure 5 As shown, a water level observation end 124 is provided on the outer wall of the water tank 121. By setting the water level observation end 124, the water level can be displayed intuitively through liquid level communication, so that the staff can directly and clearly observe the water level in the current water storage tank 123. This allows for car washing planning before or during car washing, avoiding situations where the washing task cannot be completed due to insufficient water.

[0043] The water level observation end 124 includes a vertically arranged installation groove 125 and an observation pipe 126 located in the installation groove 125. The top and bottom of the installation groove 125 are provided with connecting holes 127 that connect to the top and bottom of the inner water storage tank 123. The two ends of the observation pipe 126 are connected to the inner water storage tank 123 through the two connecting holes 127.

[0044] like Figures 1 to 5As shown, the second toolbox 11 has inwardly recessed or outwardly protruding reinforcing ribs 113 on at least four of its outer side walls. These reinforcing ribs 113 enhance the overall structure of the second toolbox 11, preventing deformation after repeated use. The reinforcing ribs 113 can be provided on both the top and bottom surfaces of the lid 112, as specifically... Figure 6 .

[0045] The water tank 121 has an outwardly protruding locking member 114 on its top surface, and a reinforcing rib 113 on the bottom of the tank 121 extends along the front and back of the equipment and is recessed inward. The reinforcing rib 113 is engaged with the locking member 114. This design can better ensure the stability when the second toolbox 11 is connected to the first toolbox 11.

[0046] like Figures 1 to 3 As shown, the second toolbox 11 has temporary storage sections 115 on both outer side walls, which can hold water guns 133 or other cleaning tools when cleaning the car. The second toolbox 11 has a recessed handle 116 on the rear side for opening the accommodating cavity, which makes it easier to open the lid 112.
