Description

Technical Field

[0001] This utility model belongs to the field of car wash machine technology, and in particular relates to a self-use car wash machine. Background Technology

[0002] After vehicles have been used, they inevitably get covered in dust or mud from heavy rain, requiring a trip to a professional car wash for a full cleaning. While going to a car wash is a highly effective way to clean a car, it requires car owners to bear the time and commuting costs of traveling to and from the car wash, as well as the high consumption of water and electricity and service fees, resulting in a significant increase in the cost of cleaning private cars.

[0003] Chinese patent application No. 201320717047.0 discloses a portable energy-saving car wash machine, including a foldable water tank, a working area, and a spray area arranged sequentially from top to bottom; the working area includes a power supply compartment and a supply compartment arranged sequentially; the power supply compartment is equipped with a power cord storage turntable, a power transformer, and a remote receiving device; a power cord is wound in the power cord storage turntable; the supply compartment is equipped with a high-pressure water pump, which is connected to the power cord, and a first water pipe is connected to the high-pressure water pump; the spray area includes a first storage compartment and a water pipe storage compartment arranged sequentially; the first storage compartment is equipped with a nozzle with a brush; the water pipe storage compartment is equipped with a water pipe storage turntable, and a second water pipe is wound around the water pipe storage turntable, which is connected to the nozzle.

[0004] In the above technical solution, the power cord and water pipe are stored by separate storage turntables. However, in this solution, when the car owner uses the car wash machine, the limited water capacity of the water tank means that the owner needs to frequently refill the water tank when washing the entire car. The power cord and water pipe, which are externally mounted, create resistance to the movement of the car wash machine when it moves with the machine, hindering its movement. There is also a safety hazard as the power cord and water pipe may become entangled with the wheels of the car wash machine when bending. Therefore, the owner needs to store the power cord and water pipe when using the car wash machine, but manually winding and retrieving the power cord and water pipe is time-consuming and inconvenient, failing to demonstrate the portability of the car wash machine. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a self-use car wash machine is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A self-use car wash machine includes a body and a gun body used in conjunction with the body. The body has a water tank for storing car wash water and a pump body connected to the water tank. The water outlet end of the pump body is connected to a water outlet connector. The body has a water outlet for the water outlet connector to communicate with the outside. The gun body is detachably connected to the body through a connecting pipe. A clamping and fixing component is provided in the body near the water outlet connector. When the connecting pipe passes through the water outlet and is inserted into the water outlet connector, the connection section formed between the connecting pipe and the water outlet connector is constrained by the force of the clamping and fixing component.

[0008] When the car wash machine needs to be moved, simply unlock the clamping and fixing components and remove the connecting pipe. The clamping and fixing components further ensure the sealing of the connection between the connecting pipe and the water outlet. Compared to the method of moving the car wash machine along with the power cord and water pipe, this method avoids tangling with the wheels and dragging resistance during movement, ensuring the portability and safety of the car wash machine.

[0009] The water outlet and water connector can be located on the lower side of the machine body or on the upper side of the machine body.

[0010] The lower side of the machine can be equipped with wheels to improve the mobility of the car wash machine, or a handle can be installed to allow the car wash machine to be moved by hand.

[0011] Preferably, the water outlet connector includes a large-diameter section located on the outside corresponding to the water outlet and a small-diameter section connecting the expansion section and the pump body, and the clamping point of the clamping and fixing assembly is located at the connection between the large-diameter section and the small-diameter section.

[0012] By setting large-diameter and small-diameter sections, the water outlet connector forms a stepped variable diameter structure, and the force point of the clamping and fixing component is precisely locked at the connection between the large-diameter and small-diameter sections. This causes a slight radial deformation at the step transition point due to the pressure of the clamping and fixing component, which strengthens the connection between the connecting pipe and the water outlet connector, isolates leakage paths, and ensures the sealing of the water outlet connector.

[0013] Preferably, a reduced diameter section is connected between the large diameter section and the small diameter section. The reduced diameter section has a groove in the radial direction that is tangent to the outer circular surface of the reduced diameter section. The clamping and fixing component can slide along the groove. When the clamping and fixing component slides to the first position, it can clamp the reduced diameter section. When the clamping and fixing component slides to the second position, it can release the reduced diameter section.

[0014] The stepped diameter-changing structure is formed by the large-diameter section, the reduced-diameter section and the small-diameter section arranged sequentially from the outside to the inside. The groove forms a guide rail structure for the slide rod, which guides the slide rod. The unlocking action integrates displacement guidance and human tactile positioning. Compared with traditional threaded screwing or buckle disassembly, it can avoid the use of tools and simplify the disassembly action, thereby realizing quick disassembly and assembly between the connecting pipe and the water outlet connector, and ensuring the convenience of disassembly between the connecting pipe and the water outlet connector.

[0015] The length of the groove can be perpendicular to the axis of the water outlet connector, or it can be set at an angle of less than 90 degrees to the axis of the water outlet connector.

[0016] Preferably, the clamping and fixing assembly includes a sliding rod that slides within the reduced diameter section and an abutting block for abutting the sliding rod. The connection of the connecting pipe is provided with an outwardly flared stop, which is used in conjunction with the sliding rod. When the sliding rod slides to the first position, the tail of the sliding rod pre-abuts the abutting block. When the sliding rod slides to the second position, the tail of the sliding rod is opened by the abutting block.

[0017] The intelligent switching of the clamping state is achieved through the dynamic cooperation between the slide rod and the abutment block. When the slide rod slides to the second position, the tail of the slide rod is guided to expand radially by the force of the abutment block, triggering the mechanical over-critical point release, so that the connecting pipe and the water outlet joint are instantly disengaged, realizing the pressure adaptive locking when the slide rod is in the first position, and the displacement drive self-decoupling during the process of the slide rod sliding to the second position.

[0018] Preferably, the reduced diameter section is provided with two sets of grooves symmetrically in the radial direction, and each set of grooves is provided with a sliding rod that can slide relative to each other.

[0019] By setting grooves on both sides to form a track guide system, the two slide rods are forced to maintain absolute synchronization during the sliding process. Compared with the oblique jamming that is easily caused by the traditional single-point sliding method, the clamping state switching process is smooth and without any jerking.

[0020] Preferably, the abutment block has an inclined surface facing the sliding direction of one of the slide rods, the inclined surface forming a triangular prism structure, and the cross-sectional shape of the abutment block is a right triangle.

[0021] The inclined sliding rod guides the radial expansion of the connecting pipe, enabling quick assembly and disassembly between the connecting pipe and the water outlet. After the sliding rod deforms, it can slide to the first position autonomously using its own deformation force, without the need for other reset components. This reduces the space occupied by the clamping and fixing components and improves space utilization.

[0022] Preferably, the abutment block has an inclined surface that is directly opposite to the sliding direction of the slide rod. The inclined surface corresponds one-to-one with the slide rod. The inclined surface makes the abutment block form a triangular prism structure, and the cross-sectional shape of the abutment block is an isosceles triangle.

[0023] By using two sets of symmetrically arranged grooves and sliding rods, the sliding rods can apply symmetrical forces to the reduced diameter section, preventing the water outlet connector from bending at the reduced diameter section due to the asymmetrical forces on both sides of the reduced diameter section.

[0024] Preferably, the abutment block has a reinforcing rib at at least one end along the axial direction of the water outlet connector, thereby ensuring the structural strength of the abutment block itself and preventing deformation of the abutment block.

[0025] Preferably, the reduced diameter section has a radial opening, which allows the slide rod to fit more tightly against the connecting pipe, ensuring the auxiliary fixing effect and sealing effect of the slide rod.

[0026] Preferably, the head of the slide bar is also connected to a push block, and the machine body is provided with a slide rail for the push block to protrude and for limiting the sliding direction of the push block.

[0027] The external linkage mechanism is achieved by setting the push block and the slide rail, so that the push block, as the initial end of the force transmission of the slide rod, is embedded in the slide rail of the machine body, and the internal sliding trajectory is visualized as a linear guide. The wall of the slide rail limits the push block to avoid off-center loading and jamming, and the quick disassembly and assembly logic of the connecting pipe conforms to the operator's normal operating habits.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] The stepped diameter-changing structure formed by the large-diameter section, narrow-diameter section, and small-diameter section on the water outlet connector works in conjunction with the clamping and fixing force-applying components composed of double-sided sliding rods to construct a quick-assembly and disassembly structure that ensures the connection strength and sealing of the connecting pipe through secondary axial fixation. The groove on the narrow-diameter section provides bidirectional precise guidance for the sliding rod. When the user pushes the push block, the sliding rod is forced to move along a preset path and expand or contract under the forced guidance of the groove and the abutment block. The connection pipe can be disassembled and assembled by the operator pushing the slider with a single finger, which improves the convenience of operation and ensures the portability and safety of the car wash machine.

Detailed Implementation

[0039] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] like Figure 1 As shown in the figure, this embodiment discloses a self-use car wash machine, including a body 1 and a gun body (not shown) used in conjunction with the body 1. The body 1 is provided with a base 10, a water tank 11 and an upper cover 12 that is snapped onto the water tank 11 from bottom to top. The water tank 11 is a foldable water tank that can be folded along the height direction. The upper cover 12 is hinged with a cover plate 13 that can be flipped outward. The upper cover 12 is hinged with a handle 14. When the user lifts the handle 14, the entire body 1 can be lifted. The base 10 is provided with wheels 15 on the lower side. The wheels 15 are located at the lower edge of the base 10. The number of wheels 15 is not limited here. When the user needs to move the body 1, he can move the entire car wash machine by holding the handle 14 and dragging the body 1.

[0042] The base 10 is equipped with a pump body 17, which extends upward to a water pump connector 19 for connecting to a folding water tank. The water outlet end of the pump body 17 is connected to a water outlet connector 18. The body 1 is equipped with a water outlet 16 for the water outlet connector 18 to connect to the outside. The gun body is connected to the water outlet connector 18 through a connecting pipe 2. The base 10 is equipped with a clamping and fixing component 21 near the water outlet connector 18. When the connecting pipe 2 passes through the water outlet 16 and is inserted into the water outlet connector 18, the connection section formed between the connecting pipe 2 and the water outlet connector 18 is constrained by the force of the clamping and fixing component 21.

[0043] The connection method between the connecting pipe 2 and the outlet connector 18 is the same as any existing pipe-to-pipe connection technology. The two can be connected by threads or by snap-fit, and there is no limitation here.

[0044] The water outlet connector 18 includes a large-diameter section 181, a reduced-diameter section 182, and a small-diameter section 183 arranged sequentially from the outside to the inside along the axial direction. The clamping point of the clamping and fixing component 21 corresponds to the position of the reduced-diameter section 182. The reduced-diameter section 182 has two sets of grooves 1821 symmetrically arranged in the radial direction, which are tangent to the outer circular surface of the reduced-diameter section 182. The bottom of the groove 1821 has a radial opening 1822. The clamping and fixing component 21 can slide along the groove 1821. The opening of the groove 1821 is located near the small-diameter section 183, and the bottom of the groove 1821 is located near the large-diameter section 181, so that the cross-sectional shape of the groove 1821 is an inclined U-shape. The wall of the groove 1821 is used to limit the clamping and fixing component 21 from the side.

[0045] The radial sides of the small diameter section 183 are provided with flat parts 1831 corresponding to the grooves 1821, and the flat parts 1831 facilitate the application of force to the water outlet connector 18.

[0046] The clamping and fixing assembly 21 includes two sets of sliding rods 22 located within the reduced diameter section 182 and abutting blocks 23 for abutting against the sliding rods 22. The connection of the connecting pipe 2 is provided with an outwardly flared baffle 20. Each set of grooves 1821 is provided with a sliding rod 22 that can slide relative to each other. The sliding rod 22 is inserted through the baffle 20 on the outside of the water outlet connector 18 and is used in conjunction with the sliding rod 22.

[0047] Both sets of slide bars 22 include a clamping part 221 extending into the groove 1821 and an abutting part 222 perpendicular to the clamping part 221. The clamping parts 221 on both sides gradually shorten the distance from the position away from the water outlet 18 to the position closer to the water outlet 18, thus forming a chopstick-like structure, which reduces the irreversible deformation of the slide bar 22 after repeated use and extends the service life of the slide bar 22.

[0048] The abutment block 23 has an inclined surface facing the sliding direction of the slide rod 22. The inclined surface makes the abutment block 23 form a triangular prism structure. The cross-sectional shape of the abutment block 23 is an isosceles triangle. The apex of the abutment block 23 is connected to the water outlet connector 18. The two base corners of the abutment block 23 are located away from the water outlet connector 18 and are symmetrical about the axis of the water outlet connector 18. The abutment parts 222 on both sides correspond one-to-one with the inclined surfaces on both sides of the abutment block 23.

[0049] The abutment block 23 is provided with a reinforcing rib 24 at least one end along the axial direction of the water outlet connector 18, thereby preventing the abutment block 23 from deforming.

[0050] When the slide rod 22 slides to the first position, the abutment part 222 at the tail position of the slide rod 22 pre-abuts with the inclined surface of the abutment block 23. At this time, the clamping part 221 of the slide rod 22 is located in the reduced diameter section 182 and limits the stop part 20 of the connecting pipe 2 axially and radially through the radial opening 1822 to ensure the connection strength and connection sealing of the connecting pipe 2. When the slide rod 22 slides to the second position, the abutment part 222 at the tail position of the slide rod 22 is opened by the inclined surface of the abutment block 23, thereby expanding the clamping parts 221 on both sides. At this time, the connecting pipe 2 loses the constraint of the slide rod 22.

[0051] The head of the slide bar 22 is also connected to a push block 25. The surface of the push block 25 can be set with anti-slip texture or letter protrusions to facilitate user operation, which is not limited here. The body 1 is provided with a slide rail 26 for the push block 25 to protrude and for limiting the sliding direction of the push block 25.

[0052] In the initial state, the push block 25 is located in the slide 26 away from the outlet 16, the slide rod 22 is located away from the reduced diameter section 182, and the abutment part 222 is located near the abutment block 23, i.e., the first position; when the connecting pipe 2 is unlocked, the push block 25 is located in the slide 26 near the outlet 16, the slide rod 22 is located near the reduced diameter section 182, and the abutment part 222 is located away from the abutment block 23, i.e., the second position. When the push block 25 drives the slide rod 22 to slide from the first position to the second position, the abutment part 222 slides along the inclined surface and is opened by the inclined surface.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that both sets of slide rods 22 include a clamping part 221 extending into the groove 1821 and an abutting part 222 perpendicular to the clamping part 221. The rear end of the abutting part 222 is provided with an anti-detachment part 223 parallel to the clamping part 221. The clamping part 221, the abutting part 222 and the anti-detachment part 223 form a stepped extension structure. The anti-detachment part 223 extends to the back of the abutting block 23. When the connecting pipe 2 is subjected to water pressure, the slide rod 22 prevents the clamping part 221 from bending and deforming through the force between the anti-detachment part 223 and the abutting block 23, thereby further ensuring the connection strength and connection sealing of the connecting pipe 2.
