[0065] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0066] Please refer to Figures 1 to 4. The present application discloses a cleaning machine, including a shell 1, a motor assembly 2, a pump assembly 3, a switch assembly 4 and a pipe fixing device 15, wherein the shell 1 includes a first shell 11 and a second shell 12, the first shell 11 and the second shell 12 are assembled and fixed to each other, and a receiving space 10 is formed between the first shell 11 and the second shell 12, the motor assembly 2, the pump assembly 3, the switch assembly 4 and the pipe fixing device 15 are all accommodated in the receiving space 10, and the motor assembly 2 and the pump assembly 3 are arranged longitudinally.

[0067] The cleaning machine of the present application needs to be connected to a high-pressure pipe joint (not shown). The pump assembly 3 and the high-pressure pipe joint can be used to pump water from an external source into the cleaning machine, and then pumped out through the water outlet pipe of the cleaning machine to perform high-pressure cleaning on the area to be cleaned. Therefore, the stability of the high-pressure pipe joint is particularly important. Therefore, the cleaning machine of the present application is provided with a pipe fixing device 15 to fix the high-pressure pipe joint.

[0068] Referring to Figures 6 to 8 in conjunction with Figure 2 , it should be noted that the pipe securing device 15 can be used to connect and secure most pipes, i.e., it is compatible with most pipe joints and is not limited to high-pressure pipe joints or cleaning machines. For a clearer explanation, the following description will be combined with the cleaning machine of the present application.

[0069] The pipe fixing device 15 includes a pipe interface 151, a control member 152, and a fixing member 153. The pipe interface 151 is adapted to fit a high-pressure pipe joint. The pipe interface 151 is provided with an insertion cavity 1511 extending along the insertion direction of the high-pressure pipe joint, and a positioning cavity 1512 formed on the outer wall of the pipe interface 151. The positioning cavity 1512 is connected to the insertion cavity 1511. In this embodiment, two positioning cavities 1512 are provided, and are arranged in an upper and lower position relative to each other.

[0070] The control member 152 is slidably fixed to the second housing 12 and is disposed on one side of the pipe interface 151. When the pipe joint is placed in the insertion cavity 1511, the pipe joint is gradually released as the control member 152 moves toward the pipe interface 151; and is gradually locked as the control member 152 moves away from the pipe interface 151.

[0071] The fixing member 153 includes a first end 1531 and a second end 1532 disposed opposite each other, and a fixing portion 1533 connecting the first end 1531 and the second end 1532. The first end 1531 is fixedly abutted against the second housing 12, and the second end 1532 passes through the positioning cavity 1512 and abuts against the control member 152. The fixing portion 1533 is received within the positioning cavity 1512 and partially protrudes into the insertion cavity 1511. When the pipe joint is released, the second end 1532 of the fixing member 153 is pushed by an external force, causing the fixing portion 1533 to move away from the positioning cavity 1512. When the pipe joint is locked, the second end 1532 of the fixing member 153 is not affected by external forces, causing the fixing portion 1533 to remain within the positioning cavity 1512.

[0072] Specifically, when the control member 152 is pushed to move toward the side of the pipe interface 151, the second end 1532 of the fixing member 153 is pushed so that the fixing portion 1533 moves toward the outside of the positioning cavity 1512, exposing the entire insertion cavity 1511. At this time, the high-pressure pipe joint can be inserted into the insertion cavity 1511. Then, the control member 152 is released, and the fixing member 153 drives the control member 152 to reset under the action of its own restoring force, so that the fixing portion 1533 is re-accommodated in the positioning cavity 1512 and the high-pressure pipe joint is clamped. At this time, the high-pressure pipe joint is fixed in the insertion cavity 1511. In this way, the high-pressure pipe joint is fixed simultaneously with its insertion, which is not only convenient to use, but also does not require additional parts to ensure the fixation of the high-pressure pipe joint to the pipe interface 151.

[0073] Of course, when it is necessary to pull out the high-pressure pipe joint, the control member 152 is also pushed toward the side of the pipe interface 151, so that the second end 1532 is pushed until the fixing portion 1533 moves toward the outside of the positioning cavity 1512, so that the plug-in cavity 1511 is completely exposed. At this time, the high-pressure pipe joint can be pulled out from the plug-in cavity 1511; then the control member 152 is released, so that the fixing member 153 drives the control member 152 to reset.

[0074] The control member 152 is generally U-shaped, and the contact surface 1521 between the control member 152 and the second end 1532 of the fixing member 153 is an inclined surface, so that the second end 1532 of the fixing member 153 slides along the contact surface 1521. This arrangement makes it very simple and easy for the fixing portion 1533 to move toward the outside of the positioning cavity 1512.

[0075] In this embodiment, two first ends 1531, fixing portions 1533, and second ends 1532 are provided and symmetrically arranged. The two first ends 1531 are connected to each other, so that the fixing member 153 is U-shaped as a whole. The two first ends 1531 are abutted and fixed to the second housing 12. The two fixing portions 1533 are respectively received in corresponding positioning cavities 1512 to jointly clamp the high-pressure pipe connector. The two abutting surfaces 1521 are provided to abut the two second ends 1532. Of course, in other embodiments, the specific shape of the fixing member 153 is not limited, as long as the side facing the control member 152 is open to push the fixing portion 1533 toward the outside of the positioning cavity 1512 to fully expose the insertion cavity 1511.

[0076] The two abutment surfaces 1521 are combined to form a conical surface, so that the second end 1532 of the fixing member 153 slides along the conical surface. Of course, in other embodiments, the abutment surface 1521 can also be an arc. When the plane where the top of the arc is located is higher than the plane where the positioning cavity 1512 is located, the fixing can also be released.

[0077] The control member 152 includes a base 1522 and a pusher 1520 connected to the base 1522. The base 1522 is provided with a pusher block 1524. Two abutment surfaces 1521 are provided on the side of the pusher 1520 facing the second end 1532. When the pusher block 1524 is pushed, the control member 152 as a whole moves toward the pipe interface 151. The two second ends 1532 slide along the corresponding abutment surfaces 1521, increasing the distance between the two second ends 1532. In other words, the two abutment surfaces 1521 expand the opening between the two second ends 1532, releasing the restriction of the fixing member 153 on the insertion cavity 1511.

[0078] The fixing portion 1533 extends along the pushing direction of the control member 152, and the first end 1531 and the second end 1532 both extend along the insertion direction of the high-pressure pipe connector. The first end 1531 and the second end 1532 are both arranged perpendicular to the fixing portion 1533. On the one hand, this saves space inside the second housing 12, and on the other hand, it increases the contact area between the second housing 12 and the control member 152, thereby enhancing the fixing and pushing effects.

[0079] The second housing 12 is provided with a first exposure slot 121 and a second exposure slot 122. The control member 152 is received within the receiving space 10, allowing the push block 1524 to pass through the first exposure slot 121. The pipe interface 151 is received within the receiving space 10 and exposed to the second exposure slot 122. In this embodiment, the pipe fixing device 15 is disposed on the back of the cleaning machine. The sliding distance of the push block 1524 is limited by the first exposure slot 121, thereby achieving the positioning of the control member 152.

[0080] A mounting plate 154 is fixed on the inner wall of the second shell 12, and a gap (not shown) is left between the mounting plate 154 and the second shell 12. The base 1522 is accommodated in the gap. The pushing portion 1520 is located on the outside of the mounting plate 154 and can abut against the side wall of the mounting plate 154 when the control member 152 is reset, thereby limiting the reset stroke of the control member 152.

[0081] Specifically, a hole groove 1541 is provided on the mounting plate 154 , and a corresponding screw hole 123 is provided on the second shell 12 , so that the mounting plate 154 and the second shell 12 can be fixed by passing the screw 124 through the hole groove 1541 and locking with the screw hole 123 .

[0082] Referring to Figures 1 to 7 , both the first and second housings 11 and 12 are provided with an air inlet window 131 and an air outlet window. A partition 14 is provided between the air inlet window 131 and the air outlet window, allowing external air to flow into the receiving space 10 through the air inlet window 131 under the action of the motor assembly 2 and then out through the air outlet window. Because the air inlet windows 131 and air outlet windows on the first and second housings 11 and 12 are substantially positioned correspondingly, the following description will use the air inlet window 131 and air outlet window on the second housing 12 as an example for detailed description.

[0083] The air outlet windows include a first air outlet window 132 and a second air outlet window 133. The first air outlet window 132 is disposed on a side of the second shell 12 opposite to the air inlet window 131, that is, the air inlet window 131 is disposed on one side of the second shell 12, and the first air outlet window 132 is disposed on the other side of the second shell 12. The second air outlet window 133 is disposed at the bottom of the second shell 12, and the isolation portion 14 is disposed between the air inlet window 131 and the second air outlet window 133. In this embodiment, the isolation portion 14 is an isolation rib disposed inside the second shell 12. The isolation rib can ensure that the airflow entering from the air inlet window 131 first enters the receiving space 10 and passes through the motor assembly 2 and the pump assembly 3, and then flows out from the first air outlet window 132 and the second air outlet window 133, thereby avoiding the situation where the airflow enters from the air inlet window 131 and directly flows out from the second air outlet window 133.

[0084] The cleaning machine is further provided with a cover plate 6, which at least partially covers the air inlet window 131 to reduce the entry of moisture in the external airflow through the air inlet window 131, thereby providing a moisture-proof function. Furthermore, the cover plate 6 can also serve as a decorative plate, thereby providing aesthetics while covering the air inlet window 131.

[0085] Referring to Figures 9 to 13, the motor assembly 2 includes a motor body 21, a motor housing 22, a motor fan blade 211, and a shield 23 housed within the housing space 10. The motor housing 22 at least partially houses the motor body 21, that is, the motor body 21 is at least partially placed within the motor housing 22. The motor housing 22 has an opening on at least one side and a housing cavity 220 at one end. The motor fan blade 211 is housed within the housing cavity 220 and is axially connected to the motor body 21. The shield 23 is disposed on the end of the motor housing 22 provided with the housing cavity 220 and is fixedly connected to the motor housing 22. In other words, by providing the shield 23 on the outside of the motor fan blade 211, the noise generated during operation of the motor body 21 can be reduced, effectively achieving a noise reduction effect.

[0086] A first positioning portion 231 is provided on the shield 23, and a second positioning portion 221 is correspondingly provided on the motor housing 22. The shield 23 and the motor housing 22 are fixedly connected by connecting the first positioning portion 231 and the second positioning portion 221. Specifically, the first positioning portion 231 is a positioning groove provided on the shield 23, and the second positioning portion 221 is a screw hole correspondingly provided on the motor housing 22. The first positioning portion 231 and the second positioning portion 221 are connected by a positioning member 25. When the first positioning portion 231 and the second positioning portion 221 are aligned with each other, the external positioning member 25 is used to pass through the first positioning portion 231 and cooperate with the second positioning portion 221 to achieve the fixed connection between the shield 23 and the motor housing 22. Preferably, the positioning member 25 is a screw. Such a fixing method has a simple structure and low cost.

[0087] One of the shield 23 and the motor housing 22 is provided with a slide rail 232, and the other correspondingly has a slide groove 222. The slide rail 232 is received within the slide groove 222, allowing the shield 23 to slide relative to the motor housing 22. When the shield 23 slides a certain distance relative to the motor housing 22, the first positioning portion 231 and the second positioning portion 221 align with each other. The provision of the slide rail 232 and the slide groove 222 can, to a certain extent, provide vertical positioning, facilitating screw installation and fixation.

[0088] A baffle 24 is provided at one end of the motor housing 22 near the receiving cavity 220, and the shield 23 is provided with a first edge 233 extending outward. The lower surface of the first edge 233 is higher than the upper surface of the baffle 24, so that when the shield 23 is assembled and fixed to the motor housing 22, the baffle 24 can be completely accommodated in the shield 23. The provision of the baffle 24 can seal the top of the shield 23 to prevent debris from entering.

[0089] A limiting portion 234 is provided inside the shield 23. When the shield 23 is fixedly connected to the motor housing 22, the limiting portion 234 abuts against the baffle 24. Preferably, the limiting portion 234 is a rib provided inside the shield 23, one end of the rib being fixedly connected to the inner wall of the shield 23 and the other end being suspended in the air. Thus, when the shield 23 slides relative to the motor housing 22, the rib can always maintain abutment against the outer wall of the motor housing 22, allowing the shield 23 to be stably fixed to the outside of the motor housing 22.

[0090] In this embodiment, the shield 23 is roughly square in shape, and the ribs are provided on the four inner walls of the shield 23, and some ribs are fixed on the inner walls of the shield 23 in a cantilevered manner, so that the motor housing 22 can be positioned on all four sides.

[0091] Please continue to refer to Figures 9 to 13. An isolation plate 27 is fixed to the end of the motor housing 22 away from the motor fan blades 211 to cover the end opening of the motor housing 22. A snap-fit ​​portion is provided at the edge of the motor housing 22 and one of the isolation plates 27, and a matching portion is provided at the edge of the motor housing 22 and the other of the isolation plates 27. When the isolation plates 27 are assembled to the motor housing 22 from top to bottom, the matching portion and the snap-fit ​​portion cooperate with each other. Optionally, the lower surface of the isolation plate 27 is flush with the lower surface of the motor housing 22. This arrangement not only makes the overall appearance of the motor assembly 2 beautiful, but also does not leave an assembly joint seam on the motor housing 22, preventing water vapor from entering.

[0092] Specifically, the locking portion is a rib 223 provided on the edge of the motor housing 22, and the rib 223 extends from top to bottom. The mating portion is a groove 271 formed on the edge of the isolation plate 27, and the groove 271 also extends from top to bottom. When the isolation plate 27 is assembled to the motor housing 22 from top to bottom, the rib 223 is received in the groove 271 and can slide along the groove 271. This arrangement achieves rapid assembly of the isolation plate 27 and the motor housing 22, and has a simple structure and low cost.

[0093] The isolation plate 27 has a second edge 273 extending toward the motor housing 22 at its edge. The second edge 273 is L-shaped, forming the groove 271 between the second edge 273 and the isolation plate 27. The groove 271 extends from top to bottom through the second edge 273, allowing the isolation plate 27 to be fixed to the motor housing 22 in a sliding manner.

[0094] As another implementation, a guide rail may be provided on one of the motor housing 22 and the isolation plate 27, and a corresponding track groove may be provided on the other, so that the guide rail can be accommodated in the track groove to enable the isolation plate 27 to slide relative to the motor housing 22. This makes assembly easier.

[0095] At this time, the snap-fit ​​portion is a convex rib 224 arranged on the guide rail, and the matching portion is a limiting groove 272 opened on the inner wall of the track groove. When the isolation plate 27 slides to a certain distance relative to the motor housing 22, the convex rib 224 is clamped in the limiting groove 272 to achieve the fixation of the isolation plate 27 and the motor housing 22.

[0096] Of course, as a preferred embodiment of the present application, the snap-fit ​​portion includes the rib 223 and the rib 224, and the mating portion includes the groove 271 and the limiting groove 272. In this way, the mutual cooperation between the rib 223 and the groove 271, and the mutual cooperation between the rib 224 and the limiting groove 272, can be utilized to achieve the positioning and fixation of the isolation plate 27 and the motor housing 22. Combining the positioning and fixing functions into one saves the use of other components.

[0097] The isolation plate 27 defines a cavity 274 therein, and the motor housing 22 has a corresponding protrusion 225 thereon. When the isolation plate 27 is assembled and secured to the motor housing 22, the protrusion 225 is received within the cavity 274. This increases the contact area between the isolation plate 27 and the motor housing 22 while also ensuring securement of the motor housing 22 to the isolation plate 27.

[0098] The motor body 21 is provided with a stopper 26. When the motor housing 22 slides a certain distance outside the motor body 21, the motor housing 22 abuts against the stopper 26 and is positioned. Preferably, the stopper 26 is a stopper plate provided on the motor body 21, with the upper surface of the stopper plate lower than the lower surface of the protrusion 225. This helps determine the sliding distance of the motor housing 22.

[0099] The stop portion 26 has a stepped structure of at least three layers, wherein the first step 261 is flush with the upper surface of the motor body 21, the second step 262 is higher than the first step 261 and can be accommodated in the motor housing 22, and the upper surface of the third step 263 is lower than the lower surface of the protrusion 225. The three-layer stepped structure ensures that the stop portion 26 and the motor body 21 are fully in contact and fixed.

[0100] Referring to Figures 14 to 17 in conjunction with Figures 4 and 5 , the switch assembly 4 is located between the motor assembly 2 and the pump assembly 3 and is fixedly connected to the pump assembly 3 and the housing 1 , respectively. This arrangement can save space inside the housing 1 as much as possible.

[0101] The switch assembly 4 comprises a housing 41, an operating member 42, and a first switch 43 and a second switch 44 housed within the housing 41.

[0102] When the first operating block 421 abuts against the first end 4311 of the switch part 431, the second end 4312 of the switch part 431 is tilted, the switch part 431 is in the first state, and the first switch member 43 is started; when the operating member 42 is rotated to make the second operating block 422 abut against the second end 4312 of the switch part 431, the first end 4311 of the switch part 431 is tilted, the switch part 431 is in the second state, and the first switch member 43 is closed.

[0103] In the present application, the first operating block 421 and the second operating block 422 extend in two directions perpendicular to each other, and the outer wall surfaces of the first operating block 421 and the second operating block 422 facing the switch portion 431 are both curved surfaces, which not only increases the contact area but also facilitates the operating member 42 to control the opening and closing of the first switch member 43.

[0104] The operating member 42 includes a first portion 423 housed within the housing 41 and a second portion 424 located outside the housing 41. The first operating block 421 and the second operating block 422 are both located on the first portion 423. In other words, the operating member 42, through the second portion 424 exposed outside the housing 41, can control the on / off operation of the first switch 43 while the switch assembly 4 is sealed.

[0105] The box body 41 includes a first box body 411 and a second box body 412. The first box body 411 and the second box body 412 are assembled together to form an installation space 410. The operating member 42 and the first switch member 43 are both installed in the installation space 410. Specifically, the box body 41 is formed by the detachable assembly of the first box body 411 and the second box body 412. At the same time, the first box body 411 and the second box body 412 are each provided with a recessed area for accommodating the first switch member 43 and the operating member 42, and are provided with positioning ribs 413 around the periphery. When the operating member 42 and the first switch member 43 are placed in the box body 41, the positioning ribs 413 in the first box body 411 and the second box body 412 engage with each other, thereby fixing the first switch member 43 and the operating member 42 in the box body 41.

[0106] In order to further save space in the box body 41 , the first switch member 43 is arranged in parallel with the operating member 42 in the installation space 410 .

[0107] The first box body 411 is provided with a slot 4112 for the operating member 42 to pass through. A latch block 4111 is protruding from the outer wall of the first box body 411, and a corresponding snap-fit ​​portion 4121 is provided on the outer wall of the second box body 412. The snap-fit ​​portion 4121 engages with the latch block 4111 to securely assemble the first and second box bodies 411 and 412. While there are various methods for securing the first and second box bodies 411 and 412, in this embodiment, the latch block 4111 and snap-fit ​​portion 4121 are used for securement, which is simple and versatile. Of course, other securing methods may also be used in other embodiments, as long as they can be disassembled when needed.

[0108] As a connection method between the switch assembly 4 and the pump assembly 3, in this embodiment, the second switch member 44 is provided with a cantilevered elastic arm 441.

The pump assembly 3 is provided with a control unit 31, which extends into the prefabricated hole 414 and abuts against the elastic arm 441 to activate or deactivate the second switch member 44.

[0109] Such an arrangement not only allows the start-stop switch of the whole machine and the gun-off stop switch, which are placed separately in the traditional design, to be accommodated in one box body 41 at the same time, but also allows the motor assembly 2 and the pump assembly 3 to be fixedly connected through the box body 41, thereby saving a large amount of space and saving production costs.

[0110] A rotating member 16 is fixed to one end of the operating member 42 located outside the box body 41. The housing 1 is provided with a rotating hole 17 that is compatible with the rotating member 16. A portion of the rotating member 16 passes through the rotating hole 17 and can rotate within the rotating hole 17 to drive the operating member 42. This arrangement allows the operating member 42 to rotate by rotating the rotating member 16 outside the housing 1, thereby activating or deactivating the entire machine start / stop switch, thereby turning the cleaning machine on and off, which is convenient to operate.

[0111] In summary, the cleaning machine of the present application has the following effects:

[0112] 1. By arranging the motor assembly 2 and the pump assembly 3 in a longitudinal arrangement, and fixing the switch assembly 4 between the motor assembly 2 and the pump assembly 3, and fixedly connecting the switch assembly 4 to the pump assembly 3 and the housing 1 respectively, the internal structure of the cleaning machine of the present application is made more compact, which not only increases the utilization rate of the internal space, but also greatly reduces the volume of the cleaning machine, making it more convenient to carry and move.

[0113] 2.

At the same time, a cover plate 6 is installed on the outside of the housing 1 of the cleaning machine to at least partially cover the air inlet window 131. This reduces the noise emitted during the operation of the cleaning machine and reduces the water vapor entering the interior of the cleaning machine through the air inlet window 131, thereby achieving the effect of moisture-proofing and noise reduction.

[0114] 3. By pushing the control member 152 toward the side of the pipe interface 151, the second end 1532 of the fixing member 153 is pushed until the fixing portion 1533 moves toward the outside of the positioning cavity 1512. At this time, the high-pressure pipe joint can be inserted into the plug-in cavity 1511; and when the control member 152 is released, the control member 152 can automatically reset under the action of the restoring force of the fixing member 153, so that the fixing portion 1533 is re-accommodated in the positioning cavity 1512 and the high-pressure pipe joint is clamped, so that the high-pressure pipe joint is fixed in the plug-in cavity 1511, thereby realizing a fixed connection between the pipe interface 151 and the high-pressure pipe joint, and the fixation is more stable.

[0115] 4. By fixing an isolation plate 27 at the end of the motor housing 22 away from the motor blades 211, the end opening of the motor housing 22 is completely covered to prevent moisture from penetrating into the motor housing 22 and causing motor corrosion.

[0116] 5. By rotating the operating member 42 housed inside the box body 41 and connected to the box body 41, the first operating block 421 and the second operating block 422 provided on the operating member 42, which extend in different directions, respectively abut against the two ends of the switch portion 431 also housed inside the box body 41, so that the switch portion 431 can switch between the first state and the second state to activate and deactivate the first switch member 43, which can effectively increase space utilization and reduce production costs.
