Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning machines, in particular to an inclined placement structure of a battery compartment of a lithium battery cleaning machine. Background Art

[0002] A high-pressure cleaning machine is a machine that uses a power device to make a high-pressure plunger pump generate high-pressure water to wash the surface of an object. It can peel off and wash away dirt to achieve the purpose of cleaning the surface of the object. Currently, the lithium battery cleaning machines in the industry basically adopt the method of setting a battery pack in the cleaning machine, and the battery pack supplies power to the power device.

[0003] Currently, the Chinese Patent Network discloses a high-pressure cleaning machine [Authorization Publication Number: CN217616337U], which includes a housing and a motor arranged in the housing, and a pump driven by the motor. The housing includes a water tank, a battery compartment located below the water tank, and an outer cover for closing the battery compartment. The water tank is located above the battery compartment. The battery compartment includes an opening, and the outer cover opens or closes the opening. The outer cover is hinged to the battery compartment in a form that can be turned over. Sealing strips are distributed around the opening, and water leakage holes are arranged on the inner wall of the battery compartment.

[0004] The above high-pressure washer has the following defects: 1. The battery compartment is set at the lower part of the high-pressure washer housing. When the battery in the battery compartment needs to be taken out or replaced, after the high-pressure washer is turned off and placed normally, the user needs to squat down to open the battery compartment and then pull out the battery pack in the battery compartment horizontally. A relatively large force is required during the process of pulling out the battery pack, making it extremely inconvenient to take out the battery, which does not conform to ergonomics; 2. When the battery compartment is set horizontally, the battery is also pushed in horizontally when being installed, and the machine is prone to tipping backward under the action of the horizontal torque; 3. When the battery compartment is set vertically, the battery needs to be taken out by completely opening the compartment cover, and the whole battery moves vertically upward until it completely detaches from the compartment body before it can be taken out, and there should be no obstacles on the upper part of the machine; 4. There is a clamping component in the battery compartment to limit the movement of the battery pack. During the process of moving the high-pressure washer, the user needs to press down the pull rod of the high-pressure washer to make the bottom end of the high-pressure washer tilt upward, thereby pushing the high-pressure washer to move. At this time, the battery pack is in an inclined state, and the end of the battery pack facing the outer cover is tilted upward. After the high-pressure washer moves to the position, the high-pressure washer needs to be restored to the normal placement state, and the high-pressure washer swings at a certain angle so that the support rod contacts the ground. At this time, the battery pack returns from the inclined state to the horizontal state. Due to the effect of inertia, the battery pack has a tendency to move horizontally and toward the outer cover direction. Since the battery pack is relatively heavy, the clamping component in the battery compartment is subjected to a relatively large inertial impact force, resulting in the clamping component being prone to damage or breakage; In addition, two sets of wheels are installed at the bottom of some high-pressure washers. When the high-pressure washer is placed vertically, the high-pressure washer can be directly pushed to move without changing the placement state of the high-pressure washer. When the high-pressure washer suddenly stops from the moving state, due to the effect of inertia, the battery pack has a tendency to move horizontally and toward the outer cover direction. Since the battery pack is relatively heavy, the clamping component in the battery compartment is subjected to a relatively large inertial impact force, resulting in the clamping component being prone to damage or breakage. Utility Model Content

[0005] The purpose of the present utility model is to propose an inclined placement structure for the battery compartment of a lithium-ion washer in view of the above problems existing in the prior art. The technical problem to be solved by the present utility model is: how to solve the problems of inconvenient taking and placing of the battery pack and easy damage of the clamping component in the battery compartment.

[0006] The purpose of the present utility model can be achieved by the following technical solutions:

[0007] A battery compartment tilted structure for a lithium battery cleaning machine comprises an outer shell, a battery compartment and a motor pump, wherein the open end of the battery compartment has a compartment opening, and is characterized in that the battery compartment is arranged in the upper part of the outer shell, and the motor pump is arranged in the lower part of the outer shell, and the outer shell comprises a front shell and a rear shell fixedly connected, and the battery compartment is arranged between the front shell and the rear shell, and the battery compartment is tilted and has an angle range of 30° to 60° with the horizontal plane, and the open end of the battery compartment is fixedly connected to the front shell, and the open end of the battery compartment is tilted upward, a battery entrance is provided at the position of the upper part of the front shell corresponding to the compartment opening, and a support portion is provided on the inner wall of the rear shell, and the bottom end of the battery compartment abuts against the support portion.

[0008] First, the structure sets the battery compartment in the upper part of the outer shell, and then sets the battery compartment at an angle, with the opening of the battery compartment facing upward, and the battery entrance is connected to the opening. When the battery pack in the battery compartment needs to be taken out, the user extracts the battery pack in the battery compartment along the inclined direction of the battery compartment. Since the battery pack is set in the upper part of the outer shell, the user does not need to squat or bend down in the process of taking out the battery pack, and after the battery pack is set at an angle, the operation of taking out the battery pack is ergonomic, making the removal of the battery pack more labor-saving and easy.

[0009] The tilted setting can avoid the problem of overturning the machine when inserting the battery pack, and it is not easy to be restricted by whether there are obstacles on the machine when removing the battery pack. Furthermore, the existing battery compartment is provided with a battery pack clamping assembly for limiting the battery pack. The clamping assembly limits the battery pack from escaping from the battery compartment in an oblique upward direction. When the high-pressure cleaning machine needs to be tilted up at the bottom and then the high-pressure cleaning machine is pushed to move, no matter how large the tilting angle of the high-pressure cleaning machine is, the battery pack at this time basically remains in an oblique upward setting, that is, the battery entrance and the compartment opening are arranged obliquely upward. When the high-pressure cleaning machine is moved into place, the high-pressure cleaning machine swings a certain angle to restore to a vertical position. In this process, the battery pack is always arranged obliquely upward. Under the action of inertia, the battery pack has a tendency to detach from the battery compartment. At this time, due to the oblique upward setting of the battery pack, the battery pack's own gravity can greatly offset this inertia, thereby significantly reducing the impact on the battery pack clamping assembly, making the battery pack clamping assembly not easy to be damaged. Some high-pressure cleaners can be pushed and moved directly in the horizontal direction. In the normal placement state, the battery pack of this structure is tilted upward. In the process of pushing the high-pressure cleaner in the horizontal direction, the state of the battery pack remains unchanged. When the high-pressure cleaner stops moving suddenly, the battery pack has a tendency to move in the horizontal direction under the action of inertia, which significantly reduces the impact on the battery pack clamping assembly, making the battery pack clamping assembly less likely to be damaged or broken. Therefore, no matter what kind of pushing method the high-pressure cleaner adopts, the impact force of the battery pack on the battery pack clamping assembly is significantly reduced.

[0010] In addition, the front housing, the rear housing, and the battery compartment of this structure are three independent components. The front housing, the rear housing, and the battery compartment are all injection-molded. During assembly, first, the open end of the battery compartment is fixedly connected to the front housing. At this time, the whole battery compartment is in a suspended state. Since the battery pack is heavy, the battery compartment is prone to deformation. The part where the open end of the battery compartment is connected to the front housing bears a large tensile force, and the open end of the battery compartment and the corresponding part of the front housing are also prone to deformation or breakage. This structure is provided with a support portion on the rear housing. After the front housing and the rear housing are snapped and fixedly connected, the support portion on the rear housing abuts against the bottom end of the battery compartment, forming a support for the bottom end of the battery compartment, so that part of the pressure is transferred to the rear housing, ensuring that the battery compartment is not easily deformed, and the part where the open end is connected to the front housing will not be deformed either, ensuring the stability of the installation of the battery compartment.

[0011] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, the open end of the battery compartment has an installation frame, the installation frame has an installation groove, and the inner wall of the upper part of the front housing has a convex platform protruding backward. The convex platform is embedded in the installation groove. Through the setting of this structure, after the installation frame is provided at the open end, the structure in which the convex platform is embedded with the installation frame improves the connection strength between the open end and the front housing, ensuring good connection stability between the open end of the battery compartment and the front housing.

[0012] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, the installation frame is in a triangular structure. The installation frame includes an upper frame portion located above the battery compartment. The upper frame portion has a first positioning portion protruding backward. The first positioning portion has a connection hole, and an installation hole one communicating with the connection hole is opened at the outer end of the first positioning portion. The inner wall of the front housing has a positioning post extending into the connection hole. The positioning post has a first threaded hole. This inclined placement structure of the battery compartment also includes a first locking screw. The first locking screw passes through the installation hole one and the connection hole and is threadedly connected to the first threaded hole. After the installation frame is set to be triangular in this structure, on the one hand, the structural strength of the installation frame is increased, thereby improving the connection strength between the installation frame and the front housing. On the other hand, the connection area between the installation frame and the battery compartment is increased within a limited space, so that after the battery pack is installed in the battery compartment, the connection part between the installation frame and the battery compartment is not easily broken; the structure in which the positioning post is inserted into the connection hole realizes pre-positioning before the installation frame is connected to the front housing, facilitating the assembly of the first locking screw, and the first locking screw is arranged horizontally to ensure that it is not easily loosened.

[0013] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, the mounting frame includes a lower frame portion located below the battery compartment. The lower frame portion has a second positioning portion protruding backward. A second threaded hole is provided in the second positioning portion. A second mounting hole coaxial with the second threaded hole is provided on the side wall of the front housing. This inclined placement structure of the battery compartment further includes a second locking screw. The second locking screw passes through the second mounting hole and is threadedly connected to the second threaded hole. Since the battery compartment is inclined, the length of the battery compartment is relatively long and partially blocks the second positioning portion. And the second positioning portion protrudes backward, that is, the second locking screw is installed horizontally, making it very difficult to assemble the second locking screw from back to front. Therefore, the second locking screw of this structure is installed from front to back, that is, the second locking screw first passes through the second mounting hole from one side of the front housing and then is threadedly connected to the second threaded hole, improving the convenience of assembling the second locking screw. And the horizontal setting of the second locking screw ensures that it is not easily loosened.

[0014] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, a triangular groove is formed between the lower frame portion and the lower side wall of the battery compartment. A first reinforcing plate connecting the lower frame portion and the battery compartment is provided in the triangular groove. When a battery pack is installed in the battery compartment, the battery compartment bears the gravity of the battery pack. At this time, the connection parts between the upper frame portion and the battery compartment and between the lower frame portion and the battery compartment are prone to deformation or fracture. The setting of the first reinforcing plate plays a supporting role for the battery compartment, preventing the suspended part of the battery compartment from deforming, and thus reducing the pressure borne between the connection parts between the upper frame portion and the battery compartment and between the lower frame portion and the battery compartment, reducing the risk of deformation or fracture.

[0015] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, a second reinforcing plate is provided between the upper frame portion and the battery compartment. The setting of the second reinforcing plate improves the structural strength between the connection parts of the upper frame portion and the battery compartment, making this part not easily deformed or fractured.

[0016] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, the upper frame portion has a third positioning post protruding along the inclined direction of the battery compartment. A third threaded hole is provided in the third positioning post. The lithium battery cleaning machine further includes a control board bracket. The control board bracket has a connecting portion. A third mounting hole is provided on the connecting portion and is arranged and penetrates along the inclined direction of the battery compartment. This inclined placement structure of the battery compartment further includes a third locking screw. The third locking screw passes through the third mounting hole and is threadedly connected to the third threaded hole. Components such as a control circuit board, a radiator, and a cooling fan need to be installed on the control board bracket. The third positioning post has a certain length. The third positioning post, the third mounting hole, and the third locking screw in this structure are all arranged along the inclined direction of the battery compartment, reducing the space occupied by the third positioning post, the connecting portion, and the third locking screw in the front-back direction, leaving sufficient space for the installation of components such as the control board bracket, the control circuit board, the radiator, and the cooling fan.

[0017] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, the bottom of the battery compartment has several support columns, there are several support parts, the support parts correspond to the support columns one by one, the support parts have pits, the support columns are embedded in the corresponding pits, and the end of the support column abuts against the bottom surface of the pit. This structure enables the rear housing to form sufficient support for the bottom of the battery compartment, reduces the risk of deformation of the battery compartment, and improves the stability of the installation of the battery compartment in the outer housing.

[0018] In the above-mentioned inclined placement structure of the battery compartment of a lithium battery cleaning machine, the support column has a mounting hole four, and an elastic ejecting component capable of ejecting the battery pack outward is arranged in the mounting hole four. Generally, an elastic ejecting component is installed in the battery compartment of an existing high-pressure cleaning machine, and the elastic ejecting component is installed in the support column. Therefore, the support column is used both for the installation of the elastic ejecting component and for forming an abutting connection with the support part of the rear housing, so that the battery compartment does not need to be provided with an additional support column structure, reducing the structural complexity of the battery compartment and facilitating processing and manufacturing.

[0019] Compared with the prior art, the inclined placement structure of the battery compartment of the lithium battery cleaning machine of the present invention has the following advantages: the battery pack of this structure is arranged at the upper position of the outer housing and is inclined. During the process of taking out the battery pack, the user does not need to squat down or bend over. After the battery pack is inclined, the operation of extracting the battery pack conforms to ergonomics, making the extraction of the battery pack more labor-saving and easy; the installation structure of the battery compartment of this structure ensures that the battery compartment is not easily deformed, and the part where the open end is connected to the front housing will not be deformed either, ensuring the stability of the installation of the battery compartment; the setting method of this structure significantly reduces the impact on the battery pack clamping component during the process of moving the high-pressure cleaning machine, making the battery pack clamping component not easily damaged or broken.

Detailed implementation manners

[0033] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0034] As Figures 1 to 5As shown, the battery compartment of the lithium battery cleaning machine has an inclined structure, including an outer shell 1, a battery compartment 2 and a motor pump 13. The open end 2a of the battery compartment 2 has a compartment opening 3. The battery compartment 2 is arranged in the upper part of the outer shell 1, and the motor pump 13 is arranged in the lower part of the outer shell 1. The outer shell 1 includes a front shell 4 and a rear shell 5 fixedly connected. The battery compartment 2 is arranged between the front shell 4 and the rear shell 5. The battery compartment 2 is inclined and the angle range with the horizontal plane is 30° to 60°. The open end 2a of the battery compartment 2 is fixedly connected to the front shell 4. In this embodiment, the open end 2a of the battery compartment 2 has a mounting frame 20, and the mounting frame 20 has a mounting groove 21. The inner wall of the upper part of the front shell 4 has a boss 43 protruding backwards, and the boss 43 is embedded in the mounting groove 21. The opening end 2a of the battery compartment 2 is arranged obliquely upward, a battery inlet 40 is provided at the upper portion of the front housing 4 at a position corresponding to the compartment opening 3, a support portion 50 is provided on the inner wall of the rear housing 5, and the bottom end 2b of the battery compartment 2 abuts against the support portion 50. A battery pack clamping assembly 11 is provided in the battery compartment 2, and when the battery pack 12 is installed in the battery compartment 2, the battery pack clamping assembly 11 is clamped with the battery pack 12 to restrict the battery pack 12 from moving toward the compartment opening 3 of the battery compartment 2. First, the structure sets the battery compartment 2 at the upper position inside the outer shell 1, and then sets the battery compartment 2 at an angle, with the hatch 3 of the battery compartment 2 facing upward at an angle, and the battery entrance 40 is connected to the hatch 3. When the battery pack 12 in the battery compartment 2 needs to be taken out, the user extracts the battery pack 12 in the battery compartment 2 along the tilted direction of the battery compartment. In the process of taking out the battery pack 12, the user does not need to squat or bend down, and after the battery pack 12 is set at an angle, the operation of extracting the battery pack 12 is ergonomic, making the removal of the battery pack 12 more labor-saving and easy. In addition, the tilted setting can avoid the problem of overturning the machine when inserting the battery pack, and it is not easy to be restricted by whether there are obstacles on the machine when taking out the battery pack.

[0035] When the bottom of the high-pressure cleaning machine needs to be lifted up before the high-pressure cleaning machine can be moved, for example, in the reference document cited in the background technology, when the high-pressure cleaning machine is moved, the pull rod needs to be pressed down so that the bottom of the high-pressure cleaning machine is lifted up before it can be moved, that is, the moving state of the high-pressure cleaning machine is as follows Figure 3 As shown, no matter how large the tilting angle of the high-pressure cleaner is, the battery pack 12 at this time basically remains tilted upward, that is, the battery inlet 40 and the compartment opening 3 are tilted upward. When the high-pressure cleaner is moved into place, the high-pressure cleaner swings a certain angle to restore to a vertical position. During this process, the battery pack 12 is also always tilted upward. Under the action of inertia, the battery pack 12 has a tendency to detach from the battery compartment. At this time, since the battery pack 12 is tilted upward, its own gravity can greatly offset this inertia, thereby significantly reducing the impact on the battery pack snap-in assembly 11, making the battery pack snap-in assembly 11 not easily damaged.

[0036] Some high-pressure cleaners can be directly pushed horizontally. In the normal placement state, for example, the high-pressure cleaner in this embodiment, that is, the moving state of the high-pressure cleaner is as follows Figure 2 As shown, two sets of wheels are provided at the bottom end of this high-pressure cleaner, which can be directly pushed horizontally. Of course, for the convenience of applying force, the high-pressure cleaner can also be pushed after pressing down the handle of the high-pressure cleaner to make the bottom end tilt up. The battery pack 12 of this structure is arranged obliquely upward. During the process of pushing the high-pressure cleaner horizontally, the state of the battery pack 12 remains unchanged. When the movement of the high-pressure cleaner suddenly stops, under the action of inertia, the battery pack 12 has a tendency to move horizontally, thereby significantly reducing the impact on the battery pack clamping assembly 11, making the battery pack clamping assembly 11 not easily damaged or broken. Therefore, no matter which pushing method is adopted for the high-pressure cleaner, the impact force of the battery pack 12 on the battery pack clamping assembly 11 is significantly reduced.

[0037] In addition, during assembly, the open end of the battery compartment 2 is first fixedly connected to the front housing 4. At this time, the whole battery compartment 2 is in a suspended state, and the battery pack 12 is relatively heavy, making the battery compartment 2 prone to deformation. The part where the open end 2a of the battery compartment 12 is connected to the front housing 4 bears a large tensile force, and the open end 2a of the battery compartment 12 and the corresponding part of the front housing 12 are also prone to deformation or the risk of fracture. This structure adopts a support portion 50 provided on the rear housing 5. After the front housing 4 and the rear housing 5 are buckled, the front housing 4 and the rear housing 5 are fixedly connected by fasteners. The support portion 50 on the rear housing 5 abuts against the bottom end 2b of the battery compartment 2 to form a support for the bottom end 2b of the battery compartment 2, so that part of the pressure is transferred to the rear housing 5, ensuring that the battery compartment 2 is not easily deformed, and the part where the open end 2a is connected to the front housing 4 will not be deformed, ensuring the stability of the installation of the battery compartment 2.

[0038] The front housing 4, the rear housing 5 and the battery compartment 2 of this structure are three independent components. The front housing 4, the rear housing 5 and the battery compartment 2 are all injection molded, which reduces the manufacturing difficulty of the components and is convenient for processing and manufacturing.

[0039] Such as Figure 2 、 Figure 6 and Figure 7As shown in the figure, the mounting frame 20 is triangular in structure. The mounting frame 20 includes an upper frame portion 200 located above the battery compartment 2. A second reinforcing plate 208 is provided between the upper frame portion 200 and the battery compartment 2. The upper frame portion 200 has a first positioning portion 201 that protrudes along the inclined direction of the battery compartment 2. The first positioning portion 201 has a connection hole 202. An installation hole 203 communicating with the connection hole 202 is provided at the outer end of the first positioning portion 201. A positioning post 41 extending into the connection hole 202 is provided on the inner wall of the front housing 4. A first threaded hole 44 is provided in the positioning post 41. The battery compartment inclined placement structure further includes a first locking screw 14. The locking screw 5 passes through the installation hole 203 and the connection hole 202 and is threadedly connected to the first threaded hole 44. In this embodiment, the first locking screw 14 is horizontally arranged. After the mounting frame 20 is arranged in a triangular shape, on the one hand, the structural strength of the mounting frame 20 is increased, thereby improving the connection strength between the mounting frame 20 and the front housing 4. On the other hand, the connection area between the mounting frame 20 and the battery compartment 2 is increased within a limited space, so that after the battery pack 12 is installed in the battery compartment 2, the connection part between the mounting frame 20 and the battery compartment 2 is not prone to breakage; the structure of inserting the positioning post 41 into the connection hole 202 realizes the pre-positioning before the connection between the mounting frame 20 and the front housing 4, facilitating the assembly of the first locking screw 14. The horizontal arrangement of the first locking screw 14 ensures that it is not prone to loosening.

[0040] As Figure 2 , Figure 8 and Figure 9 shown in the figure, the mounting frame 20 includes a lower frame portion 204 located below the battery compartment 2. The lower frame portion 204 has a second positioning portion 205 that protrudes backward. A second threaded hole 206 is provided in the second positioning portion 205. An installation hole 42 coaxially arranged with the second threaded hole 206 is provided on the side wall of the front housing 4. The battery compartment inclined placement structure further includes a second locking screw 6. The second locking screw 6 passes through the installation hole 42 and is threadedly connected to the second threaded hole 206. In this embodiment, the second locking screw 6 is horizontally arranged. Since the battery compartment 2 is inclined, the length of the battery compartment 2 is relatively long and partially blocks the second positioning portion 205. And the second positioning portion 205 protrudes backward, making it very difficult to assemble the second locking screw 6 from back to front. Therefore, the second locking screw 6 of this structure is installed from front to back, that is, the second locking screw 6 first passes through the installation hole 42 from one side of the front housing 4 and then is threadedly connected to the second threaded hole 206, improving the convenience of assembling the second locking screw 6. The horizontal arrangement of the second locking screw 6 ensures that it is not prone to loosening.

[0041] During the assembly of the battery compartment, first, the battery compartment and the front housing are pre-positioned by inserting the positioning posts 41 into the connection holes 202. Then, the first locking screws 14 are screwed into the respective holes from the direction of the battery compartment. Due to the position obstruction and interference of the battery compartment, the second locking screws 6 are screwed into the lower frame part 204 from the side of the front housing. Since the upper frame part 204 has been installed and fixed, it is ensured that the second threaded holes on the lower frame part are coaxially arranged with the second installation holes on the front housing, and only the second locking screws 6 need to be tightened.

[0042] As Figure 2 and Figure 9 shown, a triangular groove 7 is formed between the lower frame part 204 and the lower side wall of the battery compartment 2. A first reinforcing plate 207 connecting the lower frame part 204 and the battery compartment 2 is provided in the triangular groove 7. When a battery pack 12 is installed in the battery compartment 2, the battery compartment 2 bears the gravity of the battery pack 12. At this time, the connection parts between the upper frame part 200 and the battery compartment 2 and between the lower frame part 204 and the battery compartment 2 are prone to deformation or fracture. The setting of the first reinforcing plate 207 plays a supporting role for the battery compartment 2, avoiding deformation of the suspended part of the battery compartment 2, thereby reducing the pressure on the connection parts between the upper frame part 200 and the battery compartment 2 and between the lower frame part 204 and the battery compartment 2, and reducing the risk of deformation or fracture. In addition, due to the setting of the first reinforcing plate 207, the space of the triangular groove 7 is further filled, making it more difficult to install the second locking screws 6 from the side of the battery compartment 2. In this structure, the second locking screws 6 are screwed into from the side of the front housing 4, which is convenient for the installation of the second locking screws 6.

[0043] As Figure 6 , Figure 7 and Figure 12 shown, the upper frame part 200 has a third positioning post 209 protruding along the inclined direction of the battery compartment 2. A third threaded hole 210 is provided in the third positioning post 209. The lithium battery cleaning machine further includes a control board bracket 8. The control board bracket 8 has a connecting part 80. An installation hole 81 is provided on the connecting part 80 and is arranged along the inclined direction of the battery compartment 2 and penetrates through. This inclined structure of the battery compartment further includes a third locking screw 9. The third locking screw 9 passes through the installation hole 81 and is threadedly connected to the third threaded hole 210. Components such as a control circuit board, a radiator, and a cooling fan need to be installed on the control board bracket 8. The third positioning post 209 has a certain length. The third positioning post 209, the installation hole 81, and the third locking screw 9 in this structure are all arranged along the inclined direction of the battery compartment 2, reducing the space occupied by the third positioning post 81, the connecting part 80, and the third locking screw 9 in the front-rear direction, leaving sufficient space for the installation of components such as the control board bracket 8, the control circuit board, the radiator, and the cooling fan. In addition, forming the installation position of the control board bracket 8 on the battery compartment 2 is convenient for processing and manufacturing.

[0044] As Figure 2 , Figure 10 andFigure 11 As shown, the bottom of the battery compartment 2 has a plurality of support columns 211, and there are a plurality of support parts 50. The support parts 50 correspond to the support columns 211 one by one. The support parts 50 have pits 51, and the support columns 211 are embedded in the corresponding pits 51. The end of the support column 211 abuts against the bottom surface of the pit 51. In this embodiment, the battery compartment 2 has two compartments, and each compartment has two support columns 211 on its outer bottom surface. Therefore, the support parts 50 are arranged in four, and the four support parts 50 support and position the four support columns 211. The rear housing 5 forms sufficient support for the bottom of the battery compartment 2, reducing the risk of deformation of the battery compartment 2 and improving the stability of the installation of the battery compartment 2 in the outer housing 1.

[0045] As Figure 2 shown, the support column 211 has a mounting hole four 212, and an elastic ejection assembly 10 capable of ejecting the battery pack outward is arranged in the mounting hole four 212. Generally, an elastic ejection assembly 10 is installed in the battery compartment of an existing high-pressure cleaner. The elastic ejection assembly 10 is installed in the support column 211. Therefore, the support column 211 is used both for the installation of the elastic ejection assembly 10 and for forming an abutting connection with the support part 50 of the rear housing 5, so that the battery compartment 2 does not need to be provided with an additional support column structure, reducing the structural complexity of the battery compartment 2 and facilitating processing and manufacturing.
