Description

Technical Field

[0001] This utility model relates to the field of vehicle maintenance technology, and more specifically, to a mobile car wash machine with a car washing function. Background Technology

[0002] With the continuous growth of car ownership, the demand for vehicle cleaning is becoming increasingly diversified. Mobile car wash machines, due to their advantages of flexibility and convenient operation, are gradually becoming important equipment in the field of car cleaning. Among the core working components of mobile car wash machines, water pipes, as the key carrier for delivering cleaning solutions, need to be adapted to different cleaning scenarios and are usually set to a relatively long size to ensure the operating range.

[0003] However, existing mobile car wash machines have significant shortcomings in hose storage: most existing equipment lacks a dedicated hose storage mechanism, requiring operators to manually wind the hoses onto the hooks or storage racks on the machine after use. This process is time-consuming and labor-intensive, significantly increasing the operator's workload and reducing overall washing efficiency. Furthermore, manually winding the hoses makes it difficult to ensure they remain evenly and taut, leading to overlapping and twisting, causing knots that require extra time to untangle and further extending preparation time. Additionally, while some machines have simple hooks, the hoses are only temporarily secured. During mobile washing, the hoses are prone to detaching due to vibration and bumps, causing friction and damage to the ground. Loose hoses can also hinder machine movement and affect usability. Therefore, improvements are needed. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 7 As shown, this utility model provides a mobile car wash machine with a car washing function, comprising:

[0031] Fixed block 1, a rotating disk 2 is movably sleeved inside the fixed block 1, a liquid inlet chamber 33 is opened inside the rotating disk 2, a water pipe 3 is fixedly sleeved inside the rotating disk 2, the water pipe 3 is spirally wound on the rotating disk 2, the inside of the water pipe 3 is connected to the inside of the liquid inlet chamber 33, a spray gun 4 is fixedly sleeved at one end of the water pipe 3 located outside the fixed block 1, and the spray gun 4 abuts against the outer surface of the fixed block 1.

[0032] The storage mechanism is located inside the fixed block 1;

[0033] The storage mechanism includes a motor 5, the top of which is fixedly connected to the inside of a fixed block 1. A rotating shaft 6 is fixedly sleeved at the output end of the motor 5. A circular plate 7 is fixedly installed at the top of the rotating shaft 6. A square block 8 is fixedly installed on the outer surface of the circular plate 7. A first spring 9 is fixedly installed on the outer surface of the square block 8. A pawl 10 is fixedly installed at the end of the first spring 9 away from the square block 8. A fixed shaft 11 is movably sleeved inside the pawl 10. The bottom end of the fixed shaft 11 is fixedly connected to the outer surface of the circular plate 7. A ratchet 12 abuts against the outer surface of the pawl 10. The ratchet 12 is fixedly connected to the bottom end of the rotating disk 2.

[0034] Fixed block 1 provides movable fitting space for rotating disk 2. The liquid inlet chamber 33 inside rotating disk 2 is used to receive cleaning water and connect to water pipe 3 to ensure that the water flow can be stably delivered to water pipe 3. Spray gun 4 is fixed to the end of water pipe 3 that extends out of fixed block 1, serving as the spray outlet of cleaning water, making it convenient for operators to aim at the vehicle for cleaning. The motor 5 in the storage mechanism provides power for water pipe storage, and its output end drives the circular plate 7 to rotate through the rotating shaft 6. The square block 8 fixed on the circular plate 7 provides the mounting base for the first spring 9. The first spring 9 is connected to the square block 8. The block 8 and the pawl 10 provide a reset spring force for the pawl 10. The fixed shaft 11 movably connects the pawl 10 to the circular plate 7, ensuring that the pawl 10 can rotate around the fixed shaft 11. The pawl 10 cooperates with the ratchet 12 fixed at the bottom of the rotating disk 2. When the rotating disk 2 rotates forward, the ratchet 12 pushes the pawl 10 to rotate and compresses the first spring 9, without hindering the rotation of the rotating disk 2. When the motor 5 drives the circular plate 7 to rotate in reverse, the first spring 9 pushes the pawl 10 to abut against the ratchet 12, thereby driving the ratchet 12 and the rotating disk 2 to rotate in reverse, realizing the automatic winding of the water pipe 3.

[0035] Among them, a roller 15 is movably sleeved on the rotating disk 2, and the outer surface of the roller 15 is in contact with the outer surface of the water pipe 3.

[0036] Roller 15 is movably sleeved on rotating disk 2, and its outer surface is in contact with the outer surface of water pipe 3. When water pipe 3 is pulled out or retracted, the movement of water pipe 3 will drive roller 15 to rotate synchronously. Roller 15 can effectively reduce the friction force on water pipe 3, avoid wear on the outer surface of water pipe 3 due to excessive friction, and thus extend the service life of water pipe 3.

[0037] Among them, a water tank 16 is fixedly sleeved on the top of the fixed block 1, and a vent hole 17 is opened on the top of the water tank 16. A connecting pipe 18 is fixedly sleeved inside the bottom of the water tank 16. The outer surface of the connecting pipe 18 is movably sleeved with the inner surface of the top of the rotating disk 2. A liquid pump 19 is provided at the top of the connecting pipe 18.

[0038] The water tank 16 is fixedly sleeved on the top of the fixed block 1 and is used to store the cleaning water required for car washing. The vent 17 opened at the top of the water tank 16 can balance the air pressure inside the water tank 16 and prevent water flow from being affected by water pressure changes. The connecting pipe 18 is fixedly sleeved inside the bottom of the water tank 16 and is movably sleeved inside the top of the rotating disk 2, which can transport the water in the water tank 16 to the liquid inlet chamber 33 of the rotating disk 2. The liquid pump 19 is set at the top of the connecting pipe 18 to provide power for the water flow. It can pressurize the cleaning water in the water tank 16 and transport it to the connecting pipe 18, ensuring that the water flow can smoothly enter the liquid inlet chamber 33 and be sprayed out from the spray gun 4 through the water pipe 3.

[0039] The water tank 16 has an inlet 20 fixedly sleeved inside the top, and a threaded sleeve 21 is threadedly sleeved on the outer surface of the inlet 20. A hose 22 is fixedly sleeved inside the top of the threaded sleeve 21, and a connector 23 is fixedly sleeved at the end of the hose 22 away from the threaded sleeve 21.

[0040] The inlet 20 is fixedly sleeved inside the top of the water tank 16, serving as a channel for replenishing cleaning water into the water tank 16. The threaded sleeve 21 is threaded onto the outer surface of the inlet 20, used to connect the inlet 20 to the hose 22. One end of the hose 22 is fixedly sleeved onto the top of the threaded sleeve 21, and the other end can be connected to an external water source through the connector 23, making it convenient for operators to add water to the water tank 16. At the same time, the threaded connection design of the threaded sleeve 21 makes it easy for operators to unscrew the threaded sleeve 21 to remove the hose 22 from the inlet 20, thus enabling the replacement of the hose 22.

[0041] The water tank 16 has a locking block 25 fixedly installed on its outer surface, and the hose 22 is snapped into the inside of the locking block 25.

[0042] The locking block 25 is fixedly installed on the outer surface of the water tank 16. When the hose 22 does not need to be connected to an external water source, the hose 22 can be locked inside the locking block 25 to store the hose 22 and prevent the hose 22 from being placed randomly, which may cause tangling, wear or obstruction of equipment movement.

[0043] Among them, the outer surface of the threaded sleeve 21 is provided with an anti-slip block 24, which is made of rubber.

[0044] The anti-slip block 24 is set on the outer surface of the threaded sleeve 21 and is made of rubber. The rubber material has good anti-slip performance, which can increase the friction between the operator's hand and the outer surface of the threaded sleeve 21, making it easier for the operator to turn the threaded sleeve 21, and thus more convenient to install or remove the hose 22.

[0045] Among them, a base plate 13 is fixedly installed at the bottom end of the fixing block 1, and a caster wheel 14 is fixedly installed at the bottom end of the base plate 13.

[0046] The base plate 13 is fixedly installed at the bottom of the fixed block 1, providing stable support for the fixed block 1 and serving as the mounting base for the casters 14. The casters 14 are fixed at the bottom of the base plate 13, giving the car wash machine the ability to move flexibly, making it convenient for operators to push the car wash machine to different car wash locations and improving the ease of use of the equipment.

[0047] The top of the base plate 13 is fixedly installed with a telescopic sleeve 26, and a telescopic handle 27 is movably connected inside the telescopic sleeve 26. A round hole 28 is opened on the telescopic handle 27.

[0048] The telescopic sleeve 26 is fixedly installed on the top of the base plate 13. Its interior provides a movable fitting space for the telescopic handle 27. The telescopic handle 27 can move up and down along the interior of the telescopic sleeve 26, making it convenient for operators of different heights to hold and push the equipment. Multiple round holes 28 are opened on the telescopic handle 27 for cooperation with subsequent components to fix the telescopic handle 27 at different height positions, meeting the different needs of operators for handle height.

[0049] Among them, an arc-shaped block 29 is fixedly installed on the outer surface of the telescopic sleeve 26, and a paddle 30 is slidably connected inside the arc-shaped block 29. A plug rod 31 is fixedly installed on one side of the paddle 30, and the end of the plug rod 31 away from the paddle 30 is inserted into the inside of the round hole 28.

[0050] The arc-shaped block 29 is fixedly installed on the outer surface of the telescopic sleeve 26, providing sliding space for the lever 30. The lever 30 can slide along the inside of the arc-shaped block 29, and the insertion rod 31 fixed on one side of the lever 30 can move synchronously with the lever 30. When it is necessary to adjust the height of the telescopic handle 27, the lever 30 can be moved to drive the insertion rod 31 to disengage from the round hole 28 on the telescopic handle 27, thereby releasing the fixation of the telescopic handle 27 and facilitating height adjustment. After the adjustment is completed, the insertion rod 31 can be re-inserted into the corresponding round hole 28 to fix the telescopic handle 27.

[0051] A second spring 32 is fixedly installed on the other side of the paddle 30, and the end of the second spring 32 away from the paddle 30 is fixedly connected to the inside of the arc-shaped block 29.

[0052] One end of the second spring 32 is fixed to the side of the lever 30 away from the insertion rod 31, and the other end is fixed inside the arc-shaped block 29. When the lever 30 is moved to adjust the height of the telescopic handle 27, the lever 30 will compress the second spring 32. After the lever 30 is released, the second spring 32 will release its elasticity to push the lever 30 back to its original position, thereby driving the insertion rod 31 to be stably inserted into the round hole 28 of the telescopic handle 27, ensuring the stability of the telescopic handle 27 after it is fixed, and preventing the telescopic handle 27 from accidentally sliding during use.

[0053] Working principle and usage process of this utility model:

[0054] First, when the operator needs to use the mobile car wash machine, they can move the entire device by holding the telescopic handle 27. Since the bottom of the base plate 13 is equipped with casters 14, the device can be flexibly turned and moved. If the operator feels that the height of the telescopic handle 27 is not suitable for their operating habits, they can move the paddle 30 inside the arc-shaped block 29. The paddle 30 will slide along the arc-shaped block 29 and compress the second spring 32. At the same time, the insert 31 on one side of the paddle 30 will disengage from the round hole 28 on the telescopic handle 27 as the paddle moves. The operator can then pull the telescopic handle 27 up and down along the telescopic sleeve 26 until it is adjusted to a suitable height. When the lever 30 is released, the second spring 32 will push the lever 30 to reset, and the insert 31 will also be re-inserted into the corresponding round hole 28, thereby fixing the telescopic handle 27 at that height. If the water level in the water tank 16 before washing is insufficient, an external water source can be connected through the connector 23. The water source will flow into the water tank 16 through the hose 22 and the inlet 20. Since the outer surface of the threaded sleeve 21 is provided with a rubber anti-slip block 24, it can increase the friction between the hand and the threaded sleeve 21, making it convenient for the operator to unscrew the threaded sleeve 21 to disassemble the hose 22 for replacement. When the hose 22 is not in use, it can be stored in the clip 25 on the outer surface of the water tank 16.

[0055] After the equipment is moved to the target car wash location, the operator can hold the spray gun 4 placed on the outer surface of the fixed block 1 and pull it outward. At this time, the spray gun 4 will drive the water pipe 3 to be pulled out from inside the fixed block 1. Since the water pipe 3 is spirally wound inside the rotating disk 2, pulling the water pipe 3 will drive the rotating disk 2 to rotate clockwise inside the fixed block 1. At the same time, the rotating disk 2 will drive the ratchet 12 at its bottom to rotate clockwise synchronously. Due to the design of the tooth surface angle inside the ratchet 12, when the ratchet 12 rotates clockwise, it will generate a squeezing and pushing force on the pawl 10 abutting its surface, making... The pawl 10 rotates around the fixed shaft 11. During this process, the pawl 10 compresses the first spring 9 connected to the square block 8. At this time, the pawl 10 deviates from its original engagement position due to rotation and cannot block the forward rotation of the ratchet 12. Meanwhile, since the outer surface of the roller 15 movably sleeved on the rotating disk 2 is in contact with the outer surface of the water pipe 3, the water pipe 3 will drive the roller 15 to rotate when it moves. The roller 15 can effectively reduce the friction when the water pipe 3 is pulled out, avoid excessive wear on the outer surface of the water pipe 3 and extend its service life. After the water pipe 3 is extended to the length required for the car wash operation, the operator starts the liquid pump 19 at the top of the connecting pipe 18. The cleaning water in the water tank 16 will flow into the connecting pipe 18 under the action of the liquid pump 19. Since the connecting pipe 18 is movably connected to the inside of the top of the rotating disk 2, the water will enter the liquid inlet chamber 33 inside the rotating disk 2 through the connecting pipe 18. Since the inside of the water pipe 3 is connected to the inside of the liquid inlet chamber 33, the water in the liquid inlet chamber 33 will further flow into the water pipe 3 and finally spray out from the nozzle of the spray gun 4. The vent hole 17 at the top of the water tank 16 can balance the air pressure inside the water tank 16 to ensure stable water delivery. After the vehicle is washed, the operator needs to retract the water hose 3. At this time, the motor 5 inside the fixed block 1 is started. The output end of the motor 5 will drive the rotating shaft 6 to rotate in the opposite direction. The circular plate 7 fixed at the top of the rotating shaft 6 will rotate in the same direction. When the circular plate 7 rotates in the opposite direction, it will drive the pawl 10 to make a reverse circular motion through the square block 8 and the fixed shaft 11. At this time, the compressed first spring 9 will release its elasticity, pushing the outer surface of the pawl 10 to always keep in contact with the ratchet 12. The pawl 10 and the tooth surface of the ratchet 12 form an effective engagement. Therefore, when the pawl 10 rotates in the opposite direction, it will drive the ratchet 12 to rotate in the same direction. The ratchet 12 will then drive the rotating disk 2 to rotate in the opposite direction inside the fixed block 1. During the rotation of the rotating disk 2, the water hose 3 will be spirally wound around it again, realizing the automatic retraction of the water hose 3. After the water hose 3 is completely retracted, the motor 5 is turned off, and the spray gun 4 is placed back against the outer surface of the fixed block 1, completing the entire car washing and retraction process.
