Description

Technical Field

[0001] This utility model belongs to the field of car washing, and in particular relates to a portable handheld washing device. Background Technology

[0002] Currently, most car wash equipment, including portable models, requires electricity and uses a water pump to supply the washing water. This is not only costly in terms of electricity and pumps, but also limited by power supply conditions, and requires dragging a long water hose, making car washing inconvenient. Therefore, there is a need for a safe and convenient car wash tool that requires no electricity or water hoses. Utility Model Content

[0003] To change the current technological status quo, this utility model designs a novel car washing tool: a water-dispensing duster. It employs the duster cleaning method, modifying the structure of a conventional duster to achieve vehicle washing without electricity, by generating its own water and eliminating the need for a water hose. Furthermore, to meet the specific needs of car washing, it is equipped with a gentle, paint-friendly function. It is quick, convenient, and unrestricted by environmental conditions. It provides a cheap and portable car washing tool for self-service car washing.

[0004] A water-dispensing duster is included in all implementations, comprising a duster and a bucket assembly.

[0005] The duster assembly consists of a hollow handle that connects the duster head assembly to the water tank. The hollow handle is open at both ends. The plastic sleeve inside the duster head assembly fits onto the lower part of the hollow handle and is limited by upper and lower retaining rings that are embedded in the hollow handle. It can also rotate around the hollow handle.

[0006] The duster head assembly includes: a plastic sleeve, a sponge sleeve, duster bristles, and a water inlet. The hollow duster handle includes: a water outlet and a brake sleeve that fits over the hollow duster handle. The brake sleeve can slide axially on the hollow duster handle and its length is shorter than the distance from the duster head assembly to the water tank. Near the duster head assembly, it has the same outer diameter as the rotatable part of the duster head assembly. The water tank includes: a water tank lid, a water inlet, an air inlet, a press-type rebound device seat fixed to the water tank lid, a press-type rebound device fixed to the press-type rebound device seat, a press-type rebound device telescopic rod, and a mushroom-shaped plastic suction cup fixed to the press-type rebound device telescopic rod. When the press-type rebound device telescopic rod moves up and down, the mushroom-shaped plastic suction cup will block the water inlet on the water tank lid.

[0007] The water tank assembly consists of three tanks with a diameter and depth greater than the duster assembly and the water storage tank. It includes a detergent tank, a handle, a rinsing tank, a clean water tank, and a connecting block.

[0008] The cleaning tub component includes a cleaning brush, a dehydration ring, and a drain hole. The inner diameters of the cleaning brush and the dehydration ring are smaller than the outer diameter of the duster assembly, with an interference fit.

[0009] The duster bristles in the duster head assembly are made of chenille material.

[0010] This utility model provides a water-dispensing duster that requires no power source, has a simple structure, saves water and time, is portable, does not damage car paint, is lightweight, and its use is not limited by the environment. The addition of car wash wax during washing leaves the car shiny and spotless after washing. It is especially beneficial for vehicles that are frequently soiled with dust.

[0015] A water-dispensing duster features a hollow handle with open ends. One end connects to the duster head, and the other to a water reservoir. The duster head performs the washing function, using it to spray water onto the vehicle and clean its surface. The water reservoir supplies water by drawing water from the tank and raising it, allowing the water to flow through the hollow handle to the duster head. The vehicle is then cleaned by tumbling the water-filled duster head. The design also includes a cleaning brush for removing dirt and sand from the duster head; moving the brush up and down removes the dirt and sand, keeping the duster bristles clean.

[0016] The washing process requires the coordinated operation of several components. For ease of explanation, based on the car washing operation, it can be divided into a water supply system, a washing system, a cleaning and dusting system, and a watermark removal system.

[0017] The following description, in conjunction with the accompanying drawings, outlines the required components and coordination for each system.

[0018] Figure 1 This is a front view of the device of this utility model: it consists of two parts: a duster and a water bucket assembly. The upper part is the duster, which is the main handheld cleaning component. The lower part is the water bucket assembly (washing liquid bucket 12, cleaning bucket 15, and clean water bucket 24), where the washing liquid bucket 12 contains washing liquid, and the cleaning bucket 15 and clean water bucket 24 contain clean water. The cleaning bucket 15 contains components for cleaning the duster bristles 8: a cleaning brush 14 and a dehydration ring 23.

[0019] Water supply system: Refer to Figure 1 Components and Assembly: The duster consists of a hollow handle 5 connecting the duster head assembly 7 and the water storage tank 4. The hollow handle 5 is open at both ends. Water Collection Process: The water storage tank 4, located at the tail end of the hollow handle 5, is inserted into the lower half of the water tank to collect water. Inverting or raising the water storage tank 4 allows water to flow through the hollow handle 5 to the duster head assembly 7, which can then be used to dust the vehicle with water for car washing. Inserting the water storage tank 4 into the detergent tank 12 provides detergent for cleaning, while inserting it into the clean water tank 24 provides clean water for rinsing.

[0020] When drawing water, after the water storage tank 4 is full, the water inlet 16 is sealed. Raise the end of the water storage tank 4, support it with your right hand, and press the air inlet 19 with your thumb. Adjusting the air inlet 19 controls the water output of the duster assembly 7. The air inlet 19 is a small hole in the wall of the water storage tank 4 that allows air to enter, facilitating the flow of liquid to the duster assembly 7.

[0021] The water inlet of the water storage tank 4 is achieved as follows: The water tank lid 17 of the water storage tank 4 has a water inlet hole 16. A press-type rebound device seat 3 is fixed to the water tank lid 17, and a press-type rebound device 18 is fixed to the press-type rebound device seat 3. A mushroom-shaped plastic suction cup 1 is fixed to the press-type rebound device telescopic rod 2 of the press-type rebound device 18. The press-type rebound device telescopic rod 2 has two states: retracted and extended. When the water storage tank 4 is inserted into the water tank assembly, pressing the water storage tank 4 with a duster changes the state of the press-type rebound device. The linked mushroom-shaped plastic suction cup 1, because its diameter is larger than the outer diameter of the water inlet hole assembly, can open and close the water inlet hole 16 of the water tank lid 17, thereby realizing the water intake and storage functions of the water storage tank 4. (See attached diagram.) Figure 1 and Figure 3 A top view of the water storage tank to understand the interrelationship of the mushroom-shaped plastic suction cup 1, the push-to-rebound telescopic rod 2, and the push-to-rebound base components.

[0022] Washing system: Includes all components and functions of the water supply system, using car wash liquid or clean water flowing to the duster assembly 7 to dust the car surface to clean stains.

[0023] To ensure gentle cleaning of car surfaces without damaging the paint, the duster assembly 7 is not securely fixed to the hollow duster handle 5, allowing it to rotate. This allows for operation similar to a roller brush, reducing friction between the duster assembly 7 and the car surface. In the design, the plastic sleeve 9 of the inner core of the duster assembly 7 is fitted onto the hollow duster handle 5, limited by upper and lower retaining rings 20 and 22 embedded in the handle. The plastic sleeve 9 rotates around the handle 5, achieving two effects: firstly, a gentler dusting motion; and secondly, it utilizes a roller brush-like effect. This means that the duster assembly 7, carrying water, gently splashes onto the car surface, evenly and softly soaking and gently peeling away dirt and sand with excellent results. (Reference) Figure 1 and Figure 2 . Figure 2 The upper part is a top view of the duster assembly 7. The lower part is a front view and a partial cross-sectional view of the duster assembly 7. The sponge sleeve 10, duster bristles 8, water holes 21, etc. in the duster assembly 7 are all designed for water flow and gentle contact with the washing surface.

[0024] At the top of the duster head, the hollow duster handle 5 is not flush with the duster head assembly 7, and the sponge sleeve 10 extends out. In this way, the sponge sleeve 10 and the outer duster bristles 8 at the top make contact with the vehicle body more soft and flexible, which is conducive to the duster's cleaning deformation and cleaning of narrow parts of the vehicle.

[0025] Among them, the duster bristles 8 are made of chenille material. This material is soft, with long and tufted bristles, and does not easily trap dirt and sand. The stains adhering to it are completely removed by the cleaning brush 14 in the cleaning tub 15, with excellent results.

[0026] Cleaning duster system: See reference Figure 1 and Figure 4 . Figure 4 This is a top view of the washing tub 15. To remove stains from the car surface gently without damaging the paint, the duster assembly 7 must be kept clean during the washing process, and the dirt and sand adhering to the duster bristles must be removed periodically. This functional component includes the washing tub 15, the washing brush 14, and the dehydration ring 23, which work together to complete the task. The inner diameters of the washing brush 14 and the dehydration ring 23 are both smaller than the outer diameter of the duster assembly 7, and they are interference-fitted with the outer diameter of the duster assembly 7. When the duster assembly 7 is inserted into the washing tub 15 and moved up and down, the washing brush 14 brushes the duster assembly 7, removing stains from the duster bristles 8. When the duster assembly 7 is pulled out, it passes through the dehydration ring 23 to squeeze out the water from the duster assembly 7, thus drying it and preparing it for subsequent operations. Because the depth of the bucket is greater than the length of the duster assembly 7, it does not touch the bottom of the bucket during the cleaning process. The dirt and grime washed off will settle at the bottom of the cleaning bucket 15 between cleaning sessions, and the duster will not be contaminated during subsequent cleanings.

[0027] Watermark removal system: Refer to Figure 1 During the cleaning process, any remaining water on the vehicle surface needs to be removed promptly to ensure that the stains can be completely removed from the surface. This function is accomplished by sliding the brake sleeve 6. Sliding the brake sleeve 6 stops the rotation of the duster assembly 7, making the rotating duster assembly 7 and the hollow duster handle 5 a single unit. The duster bristles 8 are replaced with a brush tool to sweep the vehicle surface and remove water stains. Specifically, a brake sleeve 6 is installed outside the hollow duster handle 5. It can slide axially on the hollow duster handle 5, and its length is shorter than the distance between the duster assembly 7 and the water tank 4. Near the end of the duster assembly 7, the outer diameter of the brake sleeve 6 is the same as the outer diameter of the rotatable part of the duster assembly 7. When it is necessary to remove water stains from the vehicle surface, the brake sleeve 6 is pushed towards the duster assembly 7 and pressed to fix it. The brake sleeve 6 contacts the duster assembly 7 and generates friction, preventing the duster assembly 7 from rotating. The duster bristles 8 can then be used to sweep away the water stains from the vehicle surface.

[0028] The above description is merely an embodiment of this utility model and should not be construed as limiting the scope of this utility model. Equivalent changes made to the scope of this utility model's claims shall still fall within the protection scope of this utility model.

[0029] Based on the above embodiments, the operation of this utility model is as follows: The washing process is completed in two steps: cleaning and rinsing. Cleaning: This refers to first removing dust and mud from the car body using the washing liquid in the washing liquid bucket 12. Rinsing: This refers to rinsing off any remaining washing liquid from the car body using the clean water in the clean water bucket 24. For vehicles without severe mud or sand contamination, this tool completes the car wash process quickly and uses very little water, approximately 12 liters is sufficient. It is especially suitable for people who like cleanliness. Steps:

[0030] 1. Fill the detergent container 12, washing container 15, and clean water container 24 with clean water. Add a small capful of car wash wax to the detergent container 12 and stir to prepare the detergent solution. Car wash wax has the functions of dissolving stains, reducing friction during car washing, and increasing the shine of the car paint.

[0031] 2. Insert the duster water tank 4 into the detergent tank 12, press the duster to open the water inlet 16 of the mushroom-shaped plastic suction cup 1 on the water tank 4, allowing the detergent to flow in from the water inlet 16 of the water tank 4. Once the tank is full, press the duster again to close the mushroom-shaped plastic suction cup 1 on the water tank 4, and the water filling is complete.

[0032] 3. Pull out the duster, lift the water tank 4 with your right hand, press the air inlet 19 with your thumb, hold the duster handle with your left hand, invert the duster or raise the water tank 4, and the water will flow through the hollow duster handle 5 to the duster head assembly 7. Use the duster head assembly 7 to dust the vehicle with water to perform cleaning operations. Adjust the air intake gap of the air inlet 19 with your thumb to control the water output of the duster head assembly 7 as needed.

[0033] 4. When washing the vehicle with water, ensure that the brake sleeve 6 is positioned close to the water tank 4 so that the duster assembly 7 is rotatable. Begin washing from the top of the vehicle and gradually move downwards. During washing, the duster assembly 7 can be used for both forward and reverse brushing. When dusting areas where dirt has already been cleaned and water accumulates, you can push the brake sleeve 6 with your left hand towards the duster assembly 7 to stop it from rotating. The duster assembly 7 will then act as a brush to sweep away the water from the vehicle surface. During washing, depending on the cleanliness of the duster assembly 7, it can be inserted into the washing tub 15 and moved up and down to clean the dirt from the duster assembly 7 with clean water.

[0034] 5: Generally, the water storage tank 4 takes in the washing liquid 3 times, and the cleaning process is completed. When the washing liquid in the washing liquid tank 12 is used up, the duster assembly 7 is inserted into the cleaning tank 15 for deep cleaning of stains, and the cleaning process ends.

[0035] 6: Proceed to the cleaning stage. During the cleaning stage, the water storage tank 4 draws clean water from the clean water tank 24. For specific procedures, refer to steps 2, 3, and 4. It is not necessary to insert the duster assembly 7 into the cleaning tank 15. Clean the duster assembly 7 until the water in the clean water tank 24 is used up.

[0036] 7: For vehicle rearview mirrors, front grille, and narrow areas, use the soft part at the front of the duster assembly 7 to clean and wash them.

[0037] 8: Finally, insert the duster assembly 7 into the cleaning bucket 15 and wash the wheel hub with liquid containing detergent.

[0038] 9. Wipe the vehicle dry with a dry towel.
