Technical Field

[0001] This utility model mainly relates to the field of automotive cleaning tools, specifically a multifunctional car cleaning brush. Background Technology

[0002] Car cleaning tools refer to various tools or equipment specifically designed for cleaning the exterior, interior, and components of a car to maintain a clean appearance, hygienic interior, and good performance. Their core functions include removing stains, dust, oil, and other contaminants, and may also provide auxiliary protection for the paint and interior materials.

[0003] Among the various categories of car cleaning tools, car brushes are an important component of exterior cleaning tools. They are tools that remove dust, dirt, and water stains from the car's exterior through manual or mechanical actuation, using bristles to rub against the car's surface and in conjunction with cleaning fluid or polish. Traditional car brushes are relatively simple in function, and the cleaning brush and waxing sponge usually need to be carried and used separately, which not only increases the complexity of operation but also reduces work efficiency. Although some integrated car brush products are available on the market, they often lack a built-in wax storage unit, requiring users to still carry an additional wax container when waxing. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing car cleaning brushes are too limited in function and that the cleaning brush and waxing sponge need to be carried separately.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A multifunctional car cleaning brush includes an upper frame plate and a lower frame plate. The bottom of the upper frame plate is provided with a lower frame plate that is detachably connected to it. A handle is rotatably connected to one end of the outer wall of the upper frame plate. The handle is provided with a positioning screw at the end adjacent to the upper frame plate. A nozzle is fixedly connected to one end of the bottom of the lower frame plate.

[0007] The lower shelf has an interior compartment for storing latex wax. A flip-top door is rotatably connected to the lower shelf above the compartment. Serrated inserts are movably connected to the lower shelf through slots at both ends of its outer wall. A lever is slidably connected to one side of the lower shelf's outer wall through a groove. A first cover plate is screwed to one end of the lower shelf, and a second cover plate is screwed to one side of the lower shelf, with the second cover plate located below the first cover plate.

[0008] Furthermore, the top and edges of the upper shelf are fixedly connected with brush heads composed of fiber clusters, and the bottom of the lower shelf is glued with a sponge.

[0009] Furthermore, the end of the upper plate adjacent to the handle is a circular connecting component. The circular connecting component is fixedly connected to the inner ring of the bearing at the corresponding position inside the handle via a shaft. The surface of the handle has a through slot for installing and connecting the positioning auger. The inner wall of the slot has an internal thread that is threaded to the positioning auger.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Please refer to the appendix carefully. Figure 1-5 A multi-functional car cleaning brush includes an upper frame plate 1 and a lower frame plate 2. The bottom of the upper frame plate 1 is provided with a lower frame plate 2 that is detachably connected to it. One end of the outer wall of the upper frame plate 1 is rotatably connected to a handle 3. The handle 3 is provided with a positioning spiral 6 at the end adjacent to the upper frame plate 1. One end of the bottom of the lower frame plate 2 is fixedly connected to a nozzle 5.

[0028] The lower shelf 2 has an interior compartment for storing latex wax. A flip-top door 201 is rotatably connected to the lower shelf 2 above the compartment. A serrated insert 202 is movably connected to the lower shelf 2 through slots at both ends of its outer wall. A lever 203 is slidably connected to one side of the outer wall of the lower shelf 2 through a groove. A first cover plate 204 is connected to the top of the lower shelf 2 by screws. A second cover plate 205 is connected to the side of one end of the lower shelf 2 by screws. The second cover plate 205 is located below the first cover plate 204.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the top and edges of the upper frame plate 1 are fixedly connected to brush heads 7 composed of fiber clusters, and the bottom of the lower frame plate 2 is glued to a sponge body 4. The fiber clusters on the surface of the brush head 7 have a top length greater than the edge, and are made of ultra-fine fiber material with extremely fine fiber diameter. At the same time, the fiber surface is treated with a nano-coating. The sponge body 4 has a double-layer composite structure. The lower layer is 5mm thick and is a high-density polyurethane sponge with a pore size of 0.1-0.2mm. The upper layer is 15mm thick and is an open-cell polyester fiber sponge with a pore size of 0.5-0.8mm.

[0030] Through the above structure, the longer top fibers of the brush head 7 can first contact and grab large particles of dirt, such as dust and sand, preventing these particles from sliding and scratching on the car paint surface, while the shorter edge fibers can penetrate deep into the crevices and grooves to clean the fine stains, achieving a comprehensive cleaning from coarse to fine.

[0031] The upper layer of the sponge 4 is responsible for storing and transporting wax liquid. Its large pore size allows it to quickly absorb a large amount of latex wax and continuously and stably replenish the wax liquid to the lower layer of sponge through capillary action. This ensures that the lower layer of sponge always has enough wax liquid available during large-area waxing, avoiding frequent interruptions in wax replenishment.

[0032] In this embodiment, as Figure 2 and Figure 3 As shown, the upper plate 1 is adjacent to the handle 3 at one end, which is a circular connecting component. The circular connecting component is fixedly connected to the inner ring of the bearing at the corresponding position inside the handle 3 through the shaft. The surface of the handle 3 is provided with a through slot for installing and connecting the positioning screw 6. The inner wall of the slot is provided with an internal thread that is threaded to the positioning screw 6. The surface of the circular connecting component is provided with a slot that is threaded to the positioning screw 6 at the corresponding position.

[0033] With the above structure, the circular connecting part of the upper plate 1 is connected to the bearing in the handle 3 through the shaft, so that the upper plate 1 can rotate freely around the shaft and achieve multi-angle adjustment. When cleaning the car, the angle of the brush head 7 or the sponge 4 can be easily adjusted according to the shape and position of different parts of the car body. After the angle is adjusted to the appropriate position, tighten the positioning screw 6, which will press tightly against the circular connecting part. Using the friction and squeezing force of the thread, the upper plate 1 is firmly locked, preventing the angle from shifting due to force or vibration during the car cleaning process.

[0034] In this embodiment, as Figure 3 and Figure 4 As shown, the outer walls of the lower plate 2 are made of transparent acrylic material at the corresponding positions at both ends of the latex wax chamber. The bottom wall of the chamber is inclined, and its lowest point is adjacent to the nozzle 5. A micro peristaltic pump is fixedly connected inside the first cover plate 204. The micro peristaltic pump is connected to the nozzle 5 and the latex wax chamber through pipes. An alkaline battery electrically connected to the micro peristaltic pump is installed inside the second cover plate 205. The nozzle angle is 15°.

[0035] With the above structure, the two ends of the outer wall of the lower rack plate 2 are made of transparent acrylic material, which allows for direct observation of the remaining wax in the latex wax chamber, making it easy to replenish the wax in time. The bottom wall of the chamber is sloping, which allows the latex wax to flow naturally towards the nozzle 5 in the chamber by utilizing the principle of gravity, thereby improving the utilization rate of the wax. The angle of the nozzle 5 allows the sprayed latex wax to fall on the car paint surface at a specific tilt angle, which can better expand the spraying range compared to vertical spraying.

[0036] In this embodiment, as Figure 3 and Figure 4 As shown, the top of the flip door 201 has a finger-loop groove, and one end of the bottom has a circular protrusion. The lower frame plate 2 has a semi-circular latch on the inner wall of the corresponding circular protrusion, and the semi-circular latch is made of highly elastic engineering plastic.

[0037] Through the above structure, the finger-loop groove at the top of the flip door 201 provides the user with a clear point of force application. The circular protrusion at the bottom of the flip door 201 and the semi-circular snap-fit ​​on the inner wall of the lower shelf plate 2 are precisely matched to form a tight fastening structure. After the lower shelf plate 2 and the upper shelf plate 1 are installed, the flip door 201 can be tightly pressed against the bottom wall of the upper shelf plate 1, which can ensure the sealing of the wax compartment while making it easy to open and close.

[0038] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the lower frame plate 2 has a cavity for sliding connection of the serrated insert 202. A spring is provided in the cavity. One end of each serrated insert 202 is fixedly connected to one end of the adjacent spring. The other end of the spring is fixed to the inner wall of the cavity. The extension end of the lever 203 located inside the lower frame plate 2 is fixedly connected to the corresponding serrated insert 202 through an L-shaped rod.

[0039] With the above structure, the user only needs to use the thumb and forefinger to move the lever 203 inward. Through the transmission of the L-shaped rod, the serrated insert 202 can be easily moved inward to retract / expand. At this time, the lower shelf 2 can be quickly disassembled / installed with the upper shelf 1. The whole process does not require the assistance of tools and can be operated with one hand, which greatly shortens the time for changing latex wax and improves the efficiency of use.

[0040] In this embodiment, as Figure 3 and Figure 5 As shown, the serrated insert 202 and the inner wall of the cavity form an elastic reset structure through a spring, and the levers 203 form a relative movement. The bottom of the upper frame plate 1 is provided with a quadrilateral slot for inserting into the top of the lower frame plate 2. The two sides of the quadrilateral slot are provided with strip slots for inserting into the serrated insert 202. The inner walls of the strip slots are all fixedly connected with tooth-shaped structures that mesh with the serrated insert 202.

[0041] Through the above structure, the serrated insert 202 meshes with the toothed structure of the inner wall of the strip groove, forming a gear-like meshing effect, providing strong tensile and torsional resistance. During the car wiping process, whether wiping horizontally or applying force vertically, the upper frame plate 1 and the lower frame plate 2 can be tightly fixed to prevent loosening and separation due to external force, ensuring the overall stability of the car wiping brush structure and improving the reliability of cleaning and waxing operations.

[0042] The specific operating procedure of this utility is as follows: Remove the lower shelf 2 from the upper shelf 1, hold the finger buckle groove at the top of the flip door 201 with your thumb and flip it up, pour enough latex wax into the inner latex wax chamber through the hatch, and after filling, align the round protrusion at the bottom of the flip door 201 with the semi-circular buckle on the inner wall of the lower shelf 2, press and fasten to ensure a seal and prevent leakage.

[0043] Insert the top of the lower frame plate 2 into the quadrilateral slot at the bottom of the upper frame plate 1. At the same time, use your thumb and forefinger to move the levers 203 on both sides inward, so that the serrated insert 202 retracts into the corresponding slot of the lower frame plate 2 and compresses the spring. After the lower frame plate 2 is fully inserted, its bottom will fit tightly against the bottom wall of the upper frame plate 1. Release the levers 203, and the serrated insert 202 will pop out under the action of the spring and engage with the toothed structure in the strip slot of the upper frame plate 1 to fix it, thus completing the assembly of the upper frame plate 1 and the lower frame plate 2.

[0044] If the angle of the brush head 7 needs to be adjusted, rotate the positioning screw 6 on the handle 3 to loosen the thread between it and the circular connecting part of the upper plate 1. Then, rotate the upper plate 1 to a suitable angle, such as horizontal or tilted. After the angle is determined, rotate the positioning screw 6 in the opposite direction to tighten it again and fix the position of the upper plate 1.

[0045] When there are stubborn stains such as dust, mud, bird droppings, tree sap, etc. on the car body surface, or when deep cleaning is required, use brush head 7 for cleaning, such as mud residue on the car body after rain, or insect corpses attached after high-speed driving.

[0046] Adjust the upper plate 1 so that the brush head 7 faces the car body. Utilize the fiber cluster characteristics of the brush head 7 for cleaning. The longer fibers at the bottom first absorb larger particles of dirt such as sand and leaves, while the shorter fibers at the edges penetrate deep into the gaps in the car paint to clean the fine stains. Because the microfiber is treated with a nano-coating, sewage does not easily adhere to it. When cleaning, simply wipe the brush head 7 back and forth on the stain to quickly absorb the dirt. After cleaning, rinse the brush head 7 with clean water to restore its cleanliness.

[0047] After the vehicle is cleaned, the paint needs to be maintained and protected. Use the sponge 4 with latex wax to apply the wax. Press the external power switch on the second cover 205 to turn on the micro peristaltic pump (Kamoer 12v). Under the action of the pump, the latex wax is delivered from the chamber through the pipe to the nozzle 5 tilted at 15°. The nozzle 5 sprays a small amount of latex wax onto the paint surface as a base. The lower layer of high-density sponge of the sponge 4 contacts the paint and initially pushes the sprayed wax away. With the wiping action, the wax stored in the lower layer of sponge continuously penetrates to the upper layer through capillary action, ensuring that the surface of the upper sponge is always supplied with wax, achieving a continuous and uniform waxing effect.

[0048] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
