Description

Technical Field

[0001] This utility model belongs to the field of cleaning machine technology, and in particular to a rear-mounted external reel structure for a cleaning machine. Background Technology

[0002] High-pressure washers generate high-pressure water jets to rinse the surface of objects, washing away dirt and grime. For example, a high-pressure car wash uses a pump to pressurize water, which is then sprayed from a nozzle onto the car's surface to remove oil, dust, and stains. A typical high-pressure washer usually consists of a body, a booster pump, a hose reel, water hoses, and a spray nozzle. The water hose is wound around the reel, with one end connected to the booster pump and the other end connected to the spray nozzle. The booster pump's inlet is connected to an external water hose. The high-pressure hose can be extended as needed. After use, the hose reel needs to be manually wound back up.

[0003] Currently, a high-pressure cleaner structure has been disclosed on the China Patent Network [Authorization Announcement No.: CN112477819B]. It includes a frame, a connecting plate on the left side of the frame, and a hose reel on the left side of the connecting plate. A water pipe is wound on the hose reel, forming an isolation cavity between the connecting plate and the frame. A rotating shaft is located at the center of the hose reel, with a water inlet channel inside. A water pipe connector, which is sleeved on the outside of the rotating shaft and communicates with the water inlet channel, is fixed at the center of the hose reel. One end of the water pipe is connected to the water pipe connector. A rotary joint is located at the inner end of the rotating shaft. A booster pump is located on the right side of the frame, with a water inlet connector at its inlet end. The outlet end of the booster pump is connected to the rotary joint via a connecting pipe. The external water pipe is connected to the water inlet connector on the booster pump, the water pipe on the hose reel is connected to the water pipe connector, and the rotary joint is connected to the booster pump via a connecting pipe. The booster pump pressurizes the water, which is then sprayed out from the water pipe, thus achieving high-pressure cleaning.

[0004] The aforementioned high-pressure washer structure has the following drawbacks: High-pressure washers with hose reels are generally large and heavy, resulting in poor ease of use. Furthermore, some customers have limited usage scenarios after purchasing the high-pressure washer and do not need such a long high-pressure hose, feeling it unnecessary to install a hose reel. To improve ease of use, they may want to remove the hose reel from the washer. However, the hose reel is mounted on a rotating shaft, and its installation is very cumbersome, usually done in the factory using specialized tools. Therefore, removing the hose reel from the shaft is also very difficult, requiring specialized tools. Another situation is that some customers initially purchased a high-pressure washer without a hose reel, but then need it for their specific needs. For these customers, purchasing and installing the hose reel themselves is extremely difficult, and some washers simply cannot accommodate a hose reel. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a rear-mounted external hose reel structure for a cleaning machine. The technical problem to be solved by this utility model is: how to solve the problem of inconvenient installation and disassembly of the hose reel on a high-pressure cleaner.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A rear-mounted external hose reel structure for a cleaning machine includes a housing with a high-pressure water outlet connector on one side. The structure further includes a base assembly and a hose reel. The base assembly is located on the back of the housing and is fixed to it by several screws. The base assembly includes a high-pressure adapter pipe, one end of which is connected to the high-pressure water outlet connector. The hose reel is mounted on the base assembly and includes a first wheel body and a second wheel body. Both wheel bodies have through holes, and the through holes on wheel body one and wheel body two are coaxially aligned. When the hose reel rotates circumferentially, the through holes can rotate so that each screw is sequentially located within the axial projection of the through hole.

[0008] This structure is shipped with the hose reel assembled onto the base assembly. The hose reel is very difficult to assemble and disassemble on the base assembly. That is, the hose reel and the base assembly are a single component when shipped. Since the base assembly, hose reel, and high-pressure adapter are all external, customers can choose to purchase a high-pressure cleaner with or without a hose reel.

[0009] After purchasing a high-pressure washer equipped with a hose reel, if the hose reel is not needed in the customer's application scenario, the customer can disassemble the hose reel themselves to improve ease of use. Specifically, rotate the through hole to align with one of the screws, then insert a screwdriver into the through hole so that the tip of the screwdriver is aligned with the screw, and then unscrew the screw. Then rotate the hose reel to align the through hole with the next screw, and so on, unscrewing all the screws one by one. Next, unscrew one end of the high-pressure adapter pipe from the high-pressure water outlet connector, and finally remove the base assembly from the housing. Since the hose reel and the base assembly are a single unit, the hose reel can also be removed.

[0010] After purchasing a high-pressure washer without a base assembly and hose reel, customers can order a hose reel kit when they need it during use. The manufacturer will then ship the base assembly, hose reel, and high-pressure adapter pipe directly to the customer. The base assembly, hose reel, and high-pressure adapter pipe are a single, assembled component. After receiving the components, the customer places the base assembly against the back of the machine housing and secures it to the housing with screws. The screw installation process is the reverse of the screw removal process. Finally, one end of the high-pressure adapter pipe is connected to the high-pressure water outlet connector to assemble the hose reel on the high-pressure washer.

[0011] This structure adopts an external structure for both the base assembly and the hose reel. Users can easily install and remove the hose reel from the housing using common tools, solving the pain point of the hose reel being difficult to remove on existing high-pressure washers. Users can choose whether to equip the high-pressure washer with a hose reel according to their actual usage. The ease of installation and removal of the hose reel makes the configuration selection of the high-pressure washer more convenient and flexible for users.

[0012] In the aforementioned rear-mounted external reel structure of a cleaning machine, the base assembly includes a rectangular base with mounting holes at each of its four corners. Each mounting hole contains a screw, and each screw is threaded into the machine housing. This structure ensures a secure and stable installation of the base on the machine housing.

[0013] In the aforementioned rear-mounted external hose reel structure of a cleaning machine, the middle of the outer wall of the base has a cylindrical mounting portion. The hose reel is fitted onto the mounting portion and can rotate circumferentially relative to the mounting portion. In this structure, the mounting portion supports the rotation of the hose reel, making the hose reel relatively stable during rotation and facilitating the assembly of the hose reel with the base assembly.

[0014] In the aforementioned rear-mounted external hose reel structure of a cleaning machine, the mounting part has an internal cavity and a closed outer end. A rotating hose is fixed at the middle of the outer end, with one end extending into the cavity and the other end extending out of the mounting part. A rotary joint is fitted onto the rotating hose outside the mounting part, and the rotary joint is snapped onto the hose reel. One end of the high-pressure adapter extends into the cavity and connects to one end of the rotating hose. In this structure, the rotation of the hose reel drives the rotary joint to rotate, and the rotary joint rotates relative to the rotating hose. A high-pressure water pipe is wound around the hose reel, and the rotary joint is connected to one end of the high-pressure water pipe on the hose reel. The high-pressure water from the high-pressure water outlet of the high-pressure cleaner first enters the high-pressure adapter, and then flows sequentially through the rotating hose, the rotary joint, and the high-pressure water pipe.

[0015] In the aforementioned rear-mounted external reel structure of a cleaning machine, a positioning groove is provided on the back of the housing, and the base is embedded in the positioning groove. The positioning groove pre-positions the base, facilitating subsequent fixing of the base to the housing with screws.

[0016] In the aforementioned rear-mounted external hose reel structure of a cleaning machine, the lower end of the base has a water pipe outlet. This outlet has an arc-shaped cross-section groove that communicates with a cavity. The high-pressure adapter pipe passes through this groove. This structure guides the high-pressure adapter pipe, allowing it to pass through the lower end of the base before connecting to the high-pressure water outlet connector.

[0017] Compared with the prior art, the rear-mounted external hose reel structure of the cleaning machine of this utility model has the following advantages: This structure adopts an external structure for both the base assembly and the hose reel, allowing users to easily install and remove the hose reel from the machine housing using common tools. This solves the problem of the hose reel being difficult to remove in existing high-pressure cleaners. Users can choose whether to equip the high-pressure cleaner with a hose reel based on actual usage. The ease of installation and removal of the hose reel makes the configuration selection of the high-pressure cleaner more convenient and flexible for users. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1 to 8 As shown, the rear-mounted external hose reel structure of this cleaning machine includes a housing 1. A high-pressure water outlet connector 2 is provided on one side of the housing 1. The rear-mounted external hose reel structure also includes a base assembly 3 and a hose reel 4. The base assembly 3 is located on the back of the housing 1 and is fixed to the housing 1 by a number of screws 5. The base assembly 3 includes a high-pressure adapter pipe 6. One end of the high-pressure adapter pipe 6 is connected to the high-pressure water outlet connector 2. The hose reel 4 is assembled on the base assembly 3. The hose reel 4 includes a first wheel body 40 and a second wheel body 41. Both the first wheel body 40 and the second wheel body 41 are provided with through holes 7. The through holes 7 on the first wheel body 40 and the second wheel body 41 are coaxially arranged. When the hose reel 4 rotates circumferentially, the through holes 7 can rotate so that each screw 5 is sequentially located within the axial projection of the through hole 7.

[0029] like Figure 7 As shown, the hose reel 4 is assembled onto the base assembly 3 at the factory. The hose reel 4 is very difficult to assemble and disassemble on the base assembly 3. That is, the hose reel 4 and the base assembly 3 are a single component at the factory. Since the base assembly 3, hose reel 4 and high-pressure adapter 6 are all external components of this structure, customers can choose to purchase a high-pressure cleaner with hose reel 4 or a high-pressure cleaner without hose reel 4.

[0030] like Figure 2 and Figure 3 As shown, after purchasing a high-pressure washer equipped with a hose reel 4, when the hose reel is not needed in the customer's application scenario, the customer can disassemble the hose reel themselves to improve ease of use. Specifically, rotate the through hole 7 to align with one of the screws 5, then insert a screwdriver into the through hole 7 so that the end of the screwdriver is aligned with the screw 5, then unscrew the screw 5, and then rotate the hose reel 4 to align the through hole 7 with the next screw 5, and so on, unscrewing all the screws 5 one by one. Then unscrew one end of the high-pressure adapter 6 from the high-pressure water outlet connector 2, and finally remove the base assembly 3 from the housing 1. Since the hose reel 4 and the base assembly 3 are a single component, the hose reel 4 can also be removed.

[0031] After a customer purchases a high-pressure washer without the base assembly 3 and hose reel 4, when the customer needs the hose reel 4 during use, the customer can order a hose reel kit. The manufacturer will directly ship the base assembly 3, hose reel 4, and high-pressure adapter pipe 6 to the customer. The base assembly 3, hose reel 4, and high-pressure adapter pipe 6 are a complete assembled component. After receiving the component, the customer places the base assembly 3 against the back of the housing 1 and then fixes the base assembly 3 to the housing 1 with screws 5. The installation process of screws 5 is exactly the reverse of the removal process of screws 5. Finally, connect one end of the high-pressure adapter pipe 6 to the high-pressure water outlet connector 2 to complete the assembly of the hose reel 4 on the high-pressure washer.

[0032] This structure adopts an external structure for both the base assembly 3 and the hose reel 4. Users can easily install and remove the hose reel 4 from the housing 1 using common tools, which solves the problem of the hose reel 4 being difficult to remove in existing high-pressure cleaners. Users can choose whether to equip the high-pressure cleaner with the hose reel 4 according to their actual usage. The ease of installation and removal of the hose reel 4 makes the configuration selection of the high-pressure cleaner more convenient and flexible for users.

[0033] like Figure 2 and Figure 7 As shown, in this embodiment, the base assembly 3 includes a rectangular base 30. A positioning groove 10 is provided on the back of the housing 1, and the base 30 is embedded in the positioning groove 10 to achieve pre-positioning of the base 30 before fixing with screws 5. Mounting holes 31 are provided at the four corners of the base 30, and each mounting hole 31 is provided with a screw 5, which is threaded to the housing 1. The lower end of the base 30 has a water pipe outlet 34, which has an arc-shaped through groove 340. The through groove 340 communicates with the cavity 33, and the high-pressure adapter pipe 6 is disposed through the through groove 340.

[0034] like Figure 4 and Figure 6As shown, the middle of the outer wall of the base 30 has a cylindrical mounting part 32. The hose reel 4 is sleeved on the mounting part 32 and can rotate circumferentially relative to the mounting part 32. The interior of the mounting part 32 has a cavity 33. The mounting part 32 has a closed outer end 320. A rotating pipe 8 is fixed at the middle position of the outer end 320. One end of the rotating pipe 8 extends into the cavity 33 and the other end extends out of the mounting part 32. A rotary joint 9 is sleeved on the rotating pipe 8 located outside the mounting part 32. The rotary joint 9 is snapped onto the hose reel 4. One end of the high-pressure adapter 6 extends into the cavity 33 and connects to one end of the rotating pipe 8. After the hose reel 4 rotates, it drives the rotary joint 9 to rotate. The rotary joint 9 rotates relative to the swivel tube 8. A high-pressure water pipe is wound on the hose reel 4. The rotary joint 9 is connected to one end of the high-pressure water pipe on the hose reel 4. The high-pressure water from the high-pressure water outlet 2 of the high-pressure cleaner first enters the high-pressure swivel tube 6, and then flows through the swivel tube 8, the rotary joint 9 and the high-pressure water pipe in sequence.
