Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0015] See Figure 1 This application proposes a cleaning device for cleaning dust and mud from vehicles, keeping them clean and tidy. The cleaning device 10 is a handheld structure with a built-in high-pressure water pump and a battery. Physical isolation ensures the normal operation of the high-pressure water pump. It is also equipped with a function selection module to switch between high-pressure and low-pressure operating modes.

[0016] For details, see Figure 2 The cleaning device 10 of this application includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 enclose a space for accommodating a high-pressure water pump 13. In order to ensure the stability of the high-pressure water pump 13, both the first housing 11 and the second housing 12 are constructed with slots and keyways for fixing and securing the high-pressure water pump 13. In some embodiments, the first housing 11 and the second housing 12 are constructed with corresponding fixing structures, including positioning posts and positioning grooves, fixing holes and fixing posts, etc.

[0017] See also Figure 2A third housing 14 is provided above the first housing 11. The third housing 14 has a smooth outer surface and can be snapped onto the first housing 11, making the cleaning device 10 more concise and compact overall. The third housing 14 is physically isolated from the second housing 12 to protect the electrical function module 15. The handheld part 16 is rotatably connected to the bottom of the second housing 12. The handheld part 16 can be rotated and folded for easy gripping and storage.

[0018] Combination Figure 2 and Figure 3 , Figure 3 A cross-sectional schematic diagram of the second housing 12 is shown. The second housing 12 has an integrally formed front end portion 122 and an upper end portion 123 relative to the connection portion 121 of the handle portion 16. The front end portion 122 and the upper end portion 123 together support and fix the high-pressure water pump 13. Corresponding to the water inlet of the high-pressure water pump 13, a through hole I 122a is formed in the front end portion 122 of the second housing 12 for convenient connection of the water inlet pipe connector 131. The water outlet portion of the high-pressure water pump 13 extends from the front end of the front end portion 122 of the second housing 12 and is connected to the water nozzle 132 to spray high-pressure water to clean dust and mud on the vehicle.

[0019] In some embodiments, the water nozzle 132 is mechanically connected to the outlet of the high-pressure water pump 13, including by snap-fit, threaded connection, locking, etc., for easy replacement and cleaning.

[0020] See also Figure 3 The upper part 123 of the second housing 12 is provided with a cavity 123a for accommodating the battery. The cavity 123a is physically isolated from the first housing 11 and the second housing 12 to accommodate the high-pressure water pump 13, so as to prevent water from the high-pressure water pump 13 from entering the cavity. A groove 123b for accommodating the electrical function module 15 (electronic control unit) is formed at the outlet end of the cavity 123a. In order to facilitate the assembly and fixation of the electrical function module 15, a locking protrusion is provided on the inner side of the side wall of the groove 123b to match the electrical function module 15.

[0021] See Figure 4 , Figure 4An exploded view of the electrical function module 15 is shown. The electrical function module 15 includes a PCB board 151, a light-shielding plate 152, a waterproof ring 153, a tail cover 154, a display screen 155, and a silicone plug 156. Electrical components are mounted on the PCB board to control the high-pressure water pump 13. A battery provides operating voltage to the high-pressure water pump 13 and the electrical function module 15. The PCB board 151 is fixed inside the tail cover 154, which has slots for fixing the display screen 155 and the silicone plug 156. The PCB board 151 and the display screen 155 are electrically connected. The system connects to and controls the display screen 155 to show the operating status (high pressure or low pressure) of the high-pressure water pump 13 and the battery charge. The battery can also be charged through a connector on the tail cover 154, and a silicone plug 156 is used to protect the connector. A light shield 152 is installed on the PCB board 151 corresponding to the display screen 155. The side of the tail cover 154 has a groove that matches the inner side protrusion of the groove 123b. To improve waterproofing, a waterproof ring 153 is also provided on the side of the tail cover 154.

[0022] See Figure 5a and Figure 5b , Figure 5a A schematic diagram S1 showing one side of the hand-held connection portion 121 of the second housing 12 is shown; Figure 5b A schematic diagram S2 of the other side of the handgrip connection portion 121 of the second housing 12 is shown. A first groove 121a1 is constructed on the first side S1 of the handgrip connection portion 121. The upper part 121a2 of the first groove is an arc structure, and the two sides of the arc are connected to the first groove 121a1. The diameter of the arc is greater than the width of the first groove 121a1. A second groove 121b1 is constructed on the second side S2 of the handgrip connection portion 121. The lower part 121b2 of the second groove is an arc structure, and the two sides of the arc are connected to the second groove 121b1. The diameter of the arc is greater than the width of the second groove 121b1.

[0023] See Figure 6a and Figure 6b , Figure 6a The inner structure of the first part L1 of the handheld portion is shown. Figure 6b The inner structure of the second part L2 of the handle is shown. The first part L1 and the second part L2 of the handle 16 are respectively assembled and connected to the first side and the second side of the handle connection portion 121 of the second housing 12. Specifically, a stepped hole 161 is formed at one end of the inner side of the first part L1 of the handle 16, see [reference needed]. Figure 7 The stepped hole 161 matches the button 163a at one end of the buckle 163, limiting the button within the stepped hole 161. A rectangular groove 162 is constructed on one end of the inner side of the second part L2 of the handle 16, see [reference needed]. Figure 5bThe rectangular groove 162 is shaped to match the second slide 121b1. For example, the second slide 121b1 restricts the rectangular groove 162 to slide up and down along the second slide 121b1. More specifically, the lower part 121b2 of the second slide restricts the rotational movement of the rectangular groove 162. The above structural relationship ensures that the second part L2 of the handle 16 can rotate in the lower part 121b2 of the second slide to achieve folding and storage. When the second part L2 of the handle 16 rotates to a position parallel to the second slide 121b1, the rectangular groove 162 can move upward along the second slide 121b1 to limit the second part L2 of the handle 16, preventing it from rotating.

[0024] See also Figure 6b The rectangular groove column 162 is provided with a limiting groove for limiting position. Figure 7 Clip 163 in the middle prevents the clip from rotating; see [link / reference]. Figure 7 The latch 163 has a flange corresponding to the limiting groove inside the rectangular slot 162. The top of the latch 163 is connected to the button 163a via a connecting section 163b. An engaging section 163c is provided between the connecting section 163b and the latch 163. An elastic element is provided at the bottom of the latch. With this configuration, when the latch 163 is located in the rectangular slot 162, the phase position of the latch 163 within the rectangular slot 162 can be adjusted by pressing the button 163a. ​​For details, see [link to details]. Figure 5a The connecting section 163b of the buckle 163 matches the first slide groove 121a1, and the engaging section 163c of the buckle 163 matches the upper part 121a2 of the first slide groove. The first part L1 and the second part L2 of the handle 16 are respectively assembled on the first side and the second side of the handle connecting part 121 of the second housing 12. The stepped hole 161 of the first part L1 of the handle 16 limits the button 163a of the buckle 163. At this time, the engaging section 163c of the buckle 163 is located in the upper part 121a2 of the first slide groove and is in a locked state to prevent the handle from sliding or folding during use. By pressing the button 163a, the elastic element on the buckle 163 is compressed. At this time, the connecting section 163b of the buckle 163 enters the upper part 121a2 of the first slide groove. At this time, it can be unlocked by pulling down. When the rectangular groove post 162 moves to the lower part 121b2 of the second slide groove, it can be rotated to achieve folding.

[0025] In some embodiments, a switch is provided on the handheld part 16, which is electrically connected to the PCB board 151. The switch is used to select whether the high-pressure water pump is working or stopping, as well as to switch the working mode (high pressure or low pressure).
