Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to an energy unit for a cleaning device. Background Art

[0002] Traditional car washes often occupy a space large enough to accommodate at least one vehicle. The washing process involves spraying water and cleaning fluid onto the vehicle body and scrubbing and rinsing it with large mechanical rollers. These systems are bulky, consume a lot of water and electricity, and are noisy. In recent years, with the rise in popularity of floor scrubbers, portable car scrubbers have emerged, evolving from "water-dust circulation" floor scrubbers. These scrubbers use a motor to drive a cleaning cylinder to wipe the vehicle body. The portable scrubbers are also equipped with a water supply system and sink to clean the cylinder, thereby cleaning the vehicle body. Because traditional car washes consume a lot of water and electricity and are noisy, portable car scrubbers are becoming increasingly popular with consumers.

[0003] The handles of some existing portable cleaning devices contain batteries, display panels, control panels, and other components, and can be quickly separated from the main body. However, some existing cleaning device handles are positioned at an angle of nearly 90° to the main body, which often results in a poor grip. In some cleaning device handles, components such as the battery are not tightly connected to the handle housing and other cleaning device components. Furthermore, the electrical connection between the handle and the main body can easily fail when subjected to significant external force.

[0004] The charging heads of some existing portable cleaning devices are installed on the device or handle, and no battery assembly is required to charge the portable cleaning device. When the portable cleaning device is placed in a car for charging, if the charging management unit of the portable cleaning device fails under the scorching sun on a hot summer day, it is easy to cause thermal runaway during the charging process and cause a fire.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0084] The inventors of the present invention have discovered that the handles of existing portable cleaning devices have a poor grip and that when the handles are subjected to a large external impact, electrical connection failure between the handles and the body of the device is likely to occur.

[0085] Based on this, the present invention provides a cleaning device handle and a cleaning device, which are described in detail below through specific embodiments.

[0086] In the first aspect, the present invention provides an energy unit 50, referring to Figures 1 to 9 As shown, the energy unit 50 is snap-fitted to one end of the handle 21A of the cleaning device, and the energy unit includes a shell 501, a docking assembly 50A, a snap-fit assembly 50C, an end assembly 50B, and a power supply assembly 504 sealed in the shell 501 by the docking assembly 50A and the snap-fit assembly 50C. The shell 501 has openings at both ends and can slide axially in the handle 21A, and at least one snap-fit groove 5011 is provided at one end opening; the docking assembly 50A includes a docking end cover 502 and a charging control assembly 506 installed in the docking end cover 502, and a charging hole 5021 is provided on the end surface of the docking end cover 502. The docking end cover 502 is detachably connected to the opening at one end of the shell 501 without the snap-fit groove, and the charging control assembly 506 is provided with a charging interface 506b1 and an output port (not shown in the drawings). The charging hole 5021 on the docking end cover 502 exposes the charging interface 506b1, and the docking end cover 502 is provided with a plurality of through holes (not marked in the drawings) to expose the output port; the power supply assembly is electrically connected to the charging interface 506b1 and the output port; the snap-in assembly 50C is provided with an opening at one end away from the power supply assembly 504, and the other end seals the power supply assembly 504 in the outer shell 501, and the outer edge of the snap-in assembly 50C can be snapped with the handle 21A; a display panel 509 is installed in the end assembly 50B and seals the opening of the snap-in assembly 50C; when the energy unit 50 is snapped with the handle 21A, the output port is electrically connected to the water pump assembly 10 in the cleaning device. After the energy unit 50 is pulled out from one end of the handle 21A, the charging interface 506b1 can be used to charge the power supply assembly 504.

[0087] Specifically, such as Figure 1As shown, the handle 21A is formed by extending from the cleaning device body 20 to the end away from the cleaning roller 30; the handle 21A is cylindrical, hollow inside and open at both ends, the end of the handle 21A pointing to the cleaning roller 30 of the cleaning device is open and faces the water pump assembly 10 of the cleaning device, and the end of the handle 21A away from the water pump assembly 10 can be sleeved on the outer surface of the shell 501 of the energy unit 50 and clamped with the clamping assembly 50C; the energy unit 50 provides power for the cleaning device, and the energy unit 50 includes a shell 501, a detachable connector connected to the shell 501, and a The docking assembly 50A and the clamping assembly 50C are connected, and the end assembly 50B is sealed at the opening of the clamping assembly 50C. The docking assembly 50A and the shell 501 can be inserted into the handle 21A and can slide along its axial direction to achieve abutment with the water pump assembly 10 in the cleaning device; when the energy unit 50 slides to the bottom along the inner wall of the handle 21A in the direction pointing to the cleaning roller 30 in its axial direction, that is, when the docking assembly 50A and the water pump assembly 10 are docked, the clamping assembly 50C can be clamped with the opening of the handle 21A (not marked in the drawing).

[0088] Further, such as Figures 1 to 4 As shown, an O-ring 5015 is provided on the outer surface of the shell 501 of the energy unit 50 near the clamping assembly 50C to ensure that the clamping assembly 50C can be firmly clamped with the handle 21A while also allowing the shell of the energy unit 50 and the inner wall of the handle 21A to be sealed to prevent water from flowing back into the water pump assembly 10 of the cleaning device through the gap between the energy unit 50 and the handle 21A, thereby ensuring a reliable electrical connection between the energy unit 50 and the water pump assembly 10 and avoiding a short circuit.

[0089] The energy unit provided by the present invention can be tightly clamped with the handle of the cleaning device through the clamping assembly, and the energy unit can be pushed into / taken out of the handle conveniently and quickly. The docking assembly in the energy unit electrically connects the power supply assembly and the water pump assembly, thereby achieving a detachable electrical connection between the power supply assembly of the energy unit and the handle of the cleaning device. The power supply assembly is arranged in the housing of the energy unit and the clamping assembly is provided to seal the power supply assembly against the housing of the energy unit, thereby achieving a secure installation of the power supply assembly. Through layer-by-layer assembly, the power supply assembly is tightly connected to other components of the energy unit, and the energy unit is firmly confined in the handle body, thereby ensuring the stability of its electrical connection with the water pump assembly. The handle is extended from the shell of the cleaning device to the end away from the cleaning roller. Therefore, compared with the existing cleaning device handle that is bent nearly 90°, the convenience of holding is improved. Moreover, while ensuring that the cleaning device handle is detachably electrically connected to other components of the cleaning device, since the handle is covered on the outer surface of the shell of the energy unit, the user's hand further tightens the contact between the inner wall of the handle and the shell of the energy unit while holding the handle, increasing the friction between the shell of the energy unit and the inner wall of the handle, making the energy unit less likely to loosen from the handle, and preventing the energy unit from detaching from the cleaning device handle under impact and causing electrical connection failure.

[0090] The energy unit provided by the present invention has a charging port arranged on a docking end cover that is detachably mounted on the energy unit housing. If a user wants to charge the energy unit, he must first separate the energy unit from the handle of the cleaning device, and then charge the power supply component in the energy unit through the charging port. This can avoid the user directly charging the cleaning device in the car and causing a fire due to thermal runaway during the charging process.

[0091] In one or some optional embodiments, the outer surface of the housing 501 is provided with guide grooves running through both ends thereof. Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 14 As shown, the guide groove includes a first guide groove P and a second guide groove Q. The number and layout positions of the first guide groove P and the second guide groove Q are different. The inner wall of the handle 21A is provided with corresponding first guide ribs and second guide ribs (not marked in the drawings).

[0092] Specifically, such as Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 14 As shown, the outer surface of the shell 501 is provided with two first guide grooves P passing through both ends thereof, and the outer surface of the shell 501 is provided with three second guide grooves Q passing through both ends thereof.

[0093] The guide ribs on the inner wall of the handle 21A can cooperate with the guide grooves, and the guide ribs can circumferentially limit the guide grooves, thereby improving the connection stability between the energy unit 50 and the handle 21A. When the energy unit 50 is installed in the handle 21A, after the end of the guide rib mates with the end of the guide groove, the guide rib slides along the guide groove until the engaging portion 503b of the button 503 engages with the inner wall of the handle 21A. Furthermore, the guide grooves can be unevenly distributed circumferentially on the outer wall of the housing 501, so that the guide grooves can be used to identify the installation direction. For example, three guide grooves Q are provided on one side and two guide grooves P are provided on the other side. The installation direction can be determined by the number of guide grooves, thereby ensuring installation efficiency.

[0094] In one or more optional embodiments, as Figure 6 As shown, the housing 501 is provided with a docking assembly fixing hole 5012 at the joint between the housing 501 and the docking assembly 50A, and the docking end cover 502 is provided with a fixing hole 5022 passing through its end face, and the fixing hole 5022 corresponds to the docking assembly fixing hole 5012. By screwing the screw 5023 into the fixing hole 5022 and the docking assembly fixing hole 5012 of the docking end cover 502, the docking connection between the docking end cover 502 and the housing 501 can be achieved, so as to achieve the blocking of the open end of the housing 501 by the docking assembly 50A.

[0095] In one or more optional embodiments, as Figures 6 to 9 、 Figure 14 As shown, the housing 501 and the snap-on assembly 50C are equipped with a snap-on groove 5011, a wire hole 501c, a bracket fixing hole 5013 and a guide rib 5014. The snap-on groove 5011 is used to accommodate the button 503 of the snap-on assembly 50C, the wire hole 501c is used to allow the wiring harness 509a to pass through the housing 501 and be electrically connected to the display panel 509, the bracket fixing hole 5013 is used to fix the bracket 505 of the snap-on assembly 50C to the open end of the housing 501, and the guide rib 5014 is used to guide and position the bracket 505 of the snap-on assembly 50C when it is installed at the open end of the housing 501.

[0096] In one or some optional embodiments, the snap-fit assembly 50C is cylindrical with at least one step difference, the large-diameter outer surface of the snap-fit assembly 50C is flush with the outer surface of the handle 21A, and at least one small-diameter outer surface of the snap-fit assembly 50C is snap-fitted with the inner surface of the handle 21A.

[0097] Specifically, such as Figures 1 to 9 As shown, the clamping assembly 50C is cylindrical with one end being small and the other end being large, and the outer surface of the cylindrical shape is provided with at least one step (not shown in the drawings). Figure 1As shown, the large-diameter outer surface of the clamping assembly 50C (not marked in the drawings) is flush with the outer surface of the handle 21A, and at least one small-diameter outer surface of the clamping assembly 50C (not marked in the drawings) is clamped with the inner surface of the handle 21A. After the cylindrical clamping assembly 50C blocks the opening at one end of the housing 501 of the energy unit, it allows the energy unit to have a completely smooth transition between the outer surfaces of the two after the clamping is completed with the handle. In this way, on the one hand, the integrity of the cleaning device can be reflected, and on the other hand, the user does not need to pay attention to the specific holding position when holding the cleaning device, so that the user can have a good feel when holding the handle and the clamping assembly at the same time. The cylindrical outer surface of the clamping assembly is provided with at least one step difference, which makes it easier for the small-diameter outer surface of the clamping assembly to clamp with the inner surface of the handle. If multiple layers of step difference are provided, the clamping assembly and the handle can be clamped more tightly. In this way, only a small amount of the outer surface of the snap-fit assembly 50C of the energy unit is exposed outside the handle 21A. When the user holds the handle of the cleaning device, most of the grip is still on the outer surface of the handle 21A. Even if a small amount of gripping area falls on the outer surface of the snap-fit assembly 50C, it still does not affect the user's grip on the handle 21A. At the same time, the handle 21A and the housing 501 of the energy unit 50 are slidably engaged with each other under the positive pressure of the user's hand. The relative sliding friction between the two increases, so that when the handle of the cleaning device is subjected to a large external force, the energy unit 50 can still maintain a reliable electrical connection with the water pump assembly 10 in the cleaning device. On the other hand, if Figure 1 As shown, the snap-fit assembly 50C is only exposed on the outer surface of the handle 21A at the very end of the handle 21A, which makes it convenient for the user to directly press the button 503 on the outer surface of the snap-fit assembly 50C to release the snap-fit assembly 50C from the handle 21A, making it convenient for the user to pull out the entire energy unit 50 quickly and easily.

[0098] In one or more optional embodiments, as Figures 3 to 13 As shown, the clamping assembly 50C includes a bracket 505, at least one button 503, and at least one elastic member 510; the bracket includes a T-shaped bracket body 505a, and one end of the bracket body 505a pointing to the docking end cover 502 extends outward to have a positioning wire tube 505c for sealing the housing, as shown in FIG. Figure 3 、 Figure 4As shown, the positioning wire tube 505c extends into the wire hole 1 501c, and a sealing ring (not shown in the drawings) is clamped on the positioning wire tube 505c to achieve a seal between the positioning wire tube 505c and the wire hole 1 501c. The other end of the bracket body 505a extends outward with an opening 505d, and the bracket body 505a extends upward and downward perpendicularly to its axis. A guide column (a first guide column 505b1 and a second guide column 505b2) respectively extends; the button 503 blocks the clamping groove 5011, and the button 5 03 can move linearly along the axis of the guide column to engage / unengage the handle 21A; the elastic member 510 is sandwiched between the bracket body 505a and the button 503 and is located within the guide columns (505b1, 505b2), driving the button 503 to move linearly along the axis of the guide column. The energy unit 50 is also provided with a wiring harness 509a electrically connected to the charging control assembly 506, and the other end of the wiring harness 509a passes through the positioning wire tube 505c to be electrically connected to the display panel 509. The T-shaped bracket body allows the bracket to extend outward from the positioning wire tube with one end pointing toward the docking end cap to seal the power supply assembly within the energy unit housing. At the same time, the bracket can also extend two guide columns outward toward the inner wall of the handle to restrict the button to movement only in the axial direction of the guide columns, so that the clamping assembly can engage / unengage the handle. The through positioning wire tube also facilitates the wire harness to pass through so as to be electrically connected to the display panel.

[0099] Specifically, such as 10 to Figure 13 As shown, the bracket 505 is provided with a display panel fixing hole 5052, a bracket fixing hole 5053, and a guide rib 5054. The display panel fixing hole 5052 is used to fix the display panel 509 to the bracket 505. The bracket 505 is sealed and connected to the housing 501 by screwing screws into the bracket fixing hole 5053 and the bracket mounting hole 5013. The guide rib 5054 is used to guide the bracket 505 to slide accurately into the housing 501. When assembling the clamping assembly 50C, it is necessary to first slide the bracket 505 accurately into the housing 501 through the guide rib 5054 using the bracket fixing guide groove 5014, then screw into the bracket fixing hole 5053 and the bracket mounting hole 5013 to achieve a sealed connection between the bracket 505 and the housing 501, and then fix the display panel 509 to the bracket 505 through the display panel fixing hole 5052.

[0100] Specifically, such as Figure 2 、 Figure 3 、 Figures 5 to 9As shown, a pair of engaging grooves 5011 are oppositely provided on the side walls of the housing 501; the bracket 505 blocks the opening of the housing 501, and the bracket 505 has guide posts (505b1, 505b2) extending radially outward; the elastic member 510 is installed in the guide posts (505b1, 505b2), the button 503 extends into the guide posts (505b1, 505b2) and the engaging grooves 5011 to abut against the elastic member 510, and the button 503 is engaged with the opening of the handle 21A.

[0101] In one or more optional embodiments, as Figure 10 、 Figure 11 As shown, the two side walls (not shown in the drawings) of the bracket body 505a parallel to the axis of the bracket 505 and the axis of the guide columns (505b1, 505b2) are perpendicular to the axis of the bracket and the axis of the guide columns and each has a Z-shaped reinforcing rib (a first reinforcing rib 505a1, a second reinforcing rib 505a2) extending outward. The two reinforcing ribs (505a1, 505a2) are symmetrical around the center of the bracket axis, and the reinforcing ribs include an upper horizontal edge, a vertical edge, and a lower horizontal edge (not shown in the drawings).

[0102] Further, such as Figure 10 、 Figure 11 As shown, each of the reinforcing ribs (505a1, 505a2) is provided with at least one limiting hole (limiting hole 1 505a11, limiting hole 2 505a21, limiting hole 3 505a12, limiting hole 4 505a22) at the upper horizontal edge and the lower horizontal edge, and all the limiting holes are close to the side wall.

[0103] In one or more optional embodiments, as Figure 2 、 Figure 3 As shown, the outer surface of the button 503 is flush with the surface of the step difference. The button 503 includes a button portion 503a and a clamping portion 503b connected as a whole. The outer surface of the button portion 503a is flush with the outer surface of the large diameter of the clamping component 50C, and the outer surface of the clamping portion 503b is flush with the outer surface of the small diameter of the clamping component 50C. The clamping portion 503b is provided with a clamping tooth (not shown in the drawings) protruding outward, which can be clamped in the inner wall groove of the handle 21A (see the drawings). (not marked), the outer surface of the button portion 503a is flush with the outer surface of the handle 21A, and the two form a smoothly transitioned whole. The exposed outer surface of the button portion 503a is provided with anti-slip grooves, which can prevent the cleaning device from slipping and breaking due to the user holding the handle 21A. At the same time, it also helps to remind the user through touch that the button portion 503a is different from other parts of the handle 21A, and prompts the user to press the button 503 to separate the energy unit 50 from the handle 21A.

[0104] In this embodiment, refer to Figures 1 to 9 As shown, the energy unit 50 is engaged with the handle 21A via a button 503. Since the button 503 abuts against the elastic member 510, the engaging portion 503b of the button 503 can abut against the inner wall of the handle 21A under the elastic force of the elastic member 510. Moreover, when the housing 501 is inserted into the handle 21A, the engaging portion 503b engages with the inner wall of the handle 21A, and the button portion 503a is located outside the handle 21A. Pressing the button portion 503a can compress the elastic member 510, facilitating the extraction of the energy unit 50 from the handle 21A. The outer surface of the button portion 503a of the button 503 is flush with the outer surface of the housing 501. When the cleaning device handle is held, the button 503 is not subjected to any force alone and thus cannot be accidentally pressed.

[0105] In one or more optional embodiments, as Figure 13 As shown, at least one guide-limiting tooth 503c extends from the side of the button portion 503a near the bracket 505. This guide-limiting tooth 503c, constrained by the limiting hole, can move only along the axis of the guide post. Furthermore, a limiting hook (not shown) is provided on the guide-limiting tooth to prevent the button 503 from being ejected from the bracket 505 due to the elastic force of the elastic member 510.

[0106] Specifically, such as Figure 13 As shown, the button portion 503a is provided with a first guide limit tooth 503c1 and a second guide limit tooth 503c2 on one side close to the bracket 505. The two guide limit teeth are respectively arranged on both sides of the guide column (505b1, 505b2) and are arranged one in front of the other in the direction of the bracket axis. The two guide limit teeth can slide linearly in the limit hole. Figures 6 to 9 、 Figure 13 As shown, the two buttons 503 are injection molded using the same mold. In other words, the two buttons are identical. Since the Z-shaped reinforcement ribs on the two side walls of the bracket body 505a are arranged completely symmetrically along the axis of the guide column, rotating the same button 180 degrees can continue to press the guide limit teeth into the corresponding limit holes of the opposite guide column. This design of centrally symmetrical Z-shaped reinforcement ribs and buttons can reduce the number and types of molds required to manufacture the clamping assembly 50C, reducing the number of parts required to assemble the clamping assembly 50C.

[0107] In one or more optional embodiments, as Figure 13As shown, a guide post 503d extends from the side of the button portion 503a near the bracket 505. The guide post 503d can slide linearly within the guide posts (505b1, 505b2). This further reduces the pressure on the guide limit teeth 503c to slide linearly within the limit holes, preventing the user from applying uneven force when pressing the button or breaking the guide limit teeth 503c due to excessive force when deviating from the axial direction of the guide posts. This further improves the overall service life of the snap assembly 50C under the user's habit of repeatedly disassembling and assembling the energy unit 50.

[0108] The energy unit provided by the utility model is clamped to one end of the handle of the cleaning device through a clamping assembly. By providing a button on the outer surface of the clamping assembly that can be retracted / ejected in a direction perpendicular to the axis of the energy unit, when the user needs to quickly separate the energy unit from the handle, he only needs to press the button to release the clamping assembly from the handle, thereby quickly pulling out the entire energy unit from one end of the handle.

[0109] In one or more optional embodiments, as Figure 3 、 Figure 4 、 Figures 6 to 9 As shown, the docking end cover 502 of the docking component 50A is detachably connected to the opening at one end of the shell 501 where no snap-in groove is provided. The docking end cover 502 of the docking component 50A is provided with a plurality of through holes (not marked in the drawings). The output port and the charging port of the charging control component 506 can be accessed by external devices through the through holes. The power supply component 504 is electrically connected to the charging control component 506 to realize electrical connection between the output end and the power taking electrode (not marked in the drawings) of the water pump component 10.

[0110] Furthermore, multiple pin-receiving holes (not shown) are provided at the end of the docking end cap 502. Pins (not shown) are located within these holes. These pins can be electrically connected to the positive and negative power supply terminals, as well as the positive and negative 485 communication terminals (not shown). This allows the outlet to at least partially extend beyond the bottom of the pin-receiving holes (not shown) without protruding beyond the end face of the docking end cap 502. This facilitates timely replacement and maintenance of the pins when the electrical connection between the pins and the power supply electrodes of the water pump assembly 10 becomes poor due to erosion or oxidation. When removing the energy unit 50 from the handle 21A of the cleaning device, the user does not need to worry about discharge from the outlet because the multiple pins are located below the end face of the docking end cap 502.

[0111] In one embodiment, referring to Figure 3 、 Figure 4 、 Figures 6 to 9As shown, the charging control component 506 includes a charging control board 506b and an insulating protection board 506a electrically connected to each other. The charging control board 506b is provided with a charging interface 506b1 and an output port. The charging port of the charging control component 506 is the charging interface 506b1 on the charging control board 506b. The insulating protection board 506a is electrically connected to the positive power supply interface and the negative power supply interface of the power supply component 504. The output port includes multiple external interfaces including the positive power supply interface, the negative power supply interface, the 485 communication positive interface, and the 485 communication negative interface (not shown in the figure) provided on the charging control board 506b. Specifically, as Figure 3 、 Figure 4 As shown, the power supply assembly 504 is placed between the bracket 505 and the docking assembly 50A, and abuts against the guide frame 505 and the docking end cover 502 respectively. A plurality of concave pin accommodating holes (not shown in the drawings) are provided at one end of the docking end cover 502 away from the power supply assembly 504, and the pins electrically connected to the power positive, power negative, 485 communication positive, and 485 communication negative on the charging control board 506b are respectively placed in the pin accommodating holes, and the two output poles (not shown in the drawings) of the power supply assembly 504 are electrically connected to the input positive and input negative of the insulating protection board 506a, respectively. The pins electrically connected to the power positive, power negative, 485 communication positive, and 485 communication negative on the charging control board 506b can be electrically connected to the power positive, power negative, 485 communication positive, and 485 communication negative contacts of the water pump assembly 10 (not shown in the drawings), thereby realizing a detachable electrical connection between the energy unit 50 and the cleaning device water pump assembly 10, so that the energy unit 50 can supply power to the water pump assembly 10 and simultaneously send and receive signals of related working status to each other, and can be removed for charging when the power is insufficient. It should be noted that the output ports described in this embodiment include at least a positive power supply and a negative power supply. The present invention does not specifically limit the specific communication method and interface between the charging control board 506b, the insulation protection board 506a, and the display board 509. These interfaces may be based on the I²C bus protocol or the ModBus communication protocol. Therefore, the output ports described in this invention may also include other interfaces known to those skilled in the art that enable communication between multiple control boards, and are not specifically limited here.

[0112] In one or more optional embodiments, as Figures 2 to 9 As shown, the end assembly 50B includes an end cover 508a, a display panel 509, a wear-resistant ring 508b, and a surface patch 508c; the end cover 508a covers the opening of the opening portion 505d; the display panel 509 is installed on the inner side of the end cover 508a, and the working status of the cleaning device can be displayed to the outside through the end cover 508a; the wear-resistant ring 508b is wrapped around the outer edge and end face junction of the end cover 508a; the surface patch 508c is attached to the exposed end face of the cover plate 508a, and can cover the hollow groove 508a1 and the screws for fixing the cover plate 508a.

[0113] In one or more optional embodiments, as Figure 3 、 Figure 4 、 Figures 6 to 9 As shown, a silicone cover 507a is sandwiched between the display panel 509 and the end cover 508a, and a light guide ring 507b is sandwiched between the silicone cover 507a and the end cover 508a. The silicone cover 507a and the light guide ring 507b sequentially guide the light emitted by the lamp beads (not shown in the figure) on the display panel 509 to transmit through the end cover 508a. Specifically, as Figure 8 、 Figure 9 、 Figure 12 As shown, the outer edge of the display panel 509 is provided with multiple lamp beads, which are arranged in a ring. The display panel 509 and the silicone cover 507a are provided with a number of fixing holes (not shown in the figure) corresponding to the display panel fixing holes 5052 on the bracket 505. The display panel fixing holes 5052 can be used to install and fix the display panel 509 and the silicone cover 507a to the open end of the opening portion 505d of the bracket 505. The light guide ring 507b is arranged near the silicone cover 507a and directly opposite the annular lamp bead group. The end cap 508a seals the open end of the opening portion 505d of the bracket 505 and is sandwiched between the end cap 508a and the silicone cover 507a. The light guide ring 507b can guide the light emitted by the annular lamp bead group through the end cap 508a, so that the user can easily identify the current operating status of the cleaning device and the current charging status of the energy unit. Furthermore, the display panel 509 is electrically connected to the charging control component 506, the power supply component 504, and the water pump component 10. When the water pump component 10 is in different working modes, the annular lamp bead group of the display panel 509 can emit lights of different colors, thereby serving as an indication.

[0114] In one or more optional embodiments, as Figure 8 As shown, a docking socket 509b is provided on the side of the display panel 509 facing the bracket 505, and the docking wiring harness 509a is electrically connected to the display panel 509 via the docking socket 509b. The use of the docking socket facilitates the electrical connection between the display panel 509 and other energy units during power consumption, and also facilitates the replacement of a faulty display panel 509 or wiring harness 509a during maintenance.

[0115] In one or more optional embodiments, as Figure 8As shown, a touch switch 509c is provided on the side of the display panel 509 facing away from the bracket 505. By pressing this touch switch 509c, a user can turn the cleaning device on / off, switch the operating mode of the cleaning device, or enable / disable the voice function of the cleaning device. This embodiment does not specifically limit the duration, frequency, or number of consecutive presses of the touch switch 509c that a user can press, and the corresponding specific function of the cleaning device. All improved technical solutions based on the above technical solution that can be implemented by those skilled in the art using only a touch switch are within the scope of protection of this application.

[0116] In one or more optional embodiments, as Figure 9 As shown, the end cap 508a is provided with at least one hollow slot 508a1, and the display panel 509 is provided with a touch switch (not shown in the figure). The touch switch 509c abuts the end cap 508a. Pressing the end cap 508a adjacent to the hollow slot 508a1 presses the touch switch. Pressing the power button can control the operation of the water pump assembly 10 and the cleaning roller 30.

[0117] Further, such as Figure 9 As shown, the end cap 508a is provided with two S-shaped hollow slots 508a1, which are centrally symmetrically arranged. Together, these two centrally symmetrical S-shaped hollow slots 508a1 form a nearly circular button area (not shown) on the end cap 508a, connected only by two narrow edges. The button area directly faces the touch switch and elastically abuts against it. This allows for a wider range of material properties to be selected for the end cap 508a, eliminating the concern that the end cap 508a may be too rigid to activate the touch switch on the display panel 509 through the button area.

[0118] In one or more optional embodiments, as Figure 9 、 Figure 12 、 Figure 13 As shown, the end cover 508a is provided with at least one end cover fixing hole 508a2, which corresponds to the fixing hole of the display panel 509 (not shown in the drawing) and the display panel fixing hole 5052 on the bracket 505. Screws can be screwed into the end cover fixing hole 508a2, the fixing hole of the display panel 509, and the display panel fixing hole 5052 to seal and fix the end cover 508a to the opening 505d of the bracket 505.

[0119] In one or more optional embodiments, the energy unit 50 further includes a cushion (not shown in the drawings) disposed between the bracket 505 and the power supply assembly 504. The cushion can cushion the power supply assembly 504 in the event of an impact to the energy unit 500 or the cleaning device handle as a whole. Furthermore, it helps reduce vibration during operation of the cleaning device, thereby protecting the power supply assembly 504 from loosening or damage, and ensuring that the electrical connection between the power supply assembly 504 and the water pump assembly 10 is not susceptible to failure. The cushion 506 can be made of a material such as sponge, and specific details are described in detail in the prior art and are not limited here.

[0120] Furthermore, the power supply assembly includes a battery pack and a battery pack output terminal. The battery pack and the battery pack output terminal can be specifically described in detail in the prior art and are not limited here.

[0121] In one or more optional embodiments, as Figures 6 to 9 As shown, the docking end cover 502 is also provided with corresponding first guide grooves P and second guide grooves Q at positions corresponding to the outer shell 501, so that when the energy unit 50 is first inserted into the handle 21A with the docking assembly 50A, the first guide grooves P and second guide grooves Q can be used to cooperate with the first guide ribs and second guide ribs on the inner wall of the handle 21A, and then the energy unit 50 is continuously pushed in, and the first guide grooves P and second guide grooves Q of the outer shell 501 continue to cooperate with the first guide ribs and second guide ribs on the inner wall of the handle 21A until the docking of the docking assembly 50A and the water pump assembly 10 is completed, and at the same time, the clamping of the clamping assembly 50C and the handle 21A is completed.

[0122] In the second aspect, based on the same utility model concept, the utility model also provides a cleaning device, referring to Figure 1 As shown, the cleaning device includes a cleaning device body 20 with a handle 21A, a water pump assembly 10 built into the cleaning device body 20, a water tank 40 and a cleaning roller 30 snapped onto the cleaning device body 20, and the energy unit 50 described in the first aspect. The handle 21A is cylindrical and extends from the end of the cleaning device body 20 in a direction away from the cleaning roller 30. The energy unit 50 of the cleaning device handle is electrically connected to the water pump assembly 10. The cleaning device body 20 includes a body bottom shell 21 and a body upper shell 22, which are detachable from each other.

[0123] Compared to existing cleaning devices with handles that bend nearly 90 degrees, the cleaning device provided by the present invention has a longer handle and energy unit, a slimmer power supply assembly, and a tighter connection between the power supply assembly and the housing. This not only improves the grip, but also enhances the stability of the snap-fit connection between the energy unit and the handle. Thus, when a user grips the handle of the cleaning device, they can directly grip the outer surface of the handle. While gripping the handle, the user also facilitates the relative sliding friction between the handle and the housing of the energy unit, which increases under the positive pressure of the user's hand. This allows the energy unit to maintain a reliable electrical connection with the water pump assembly within the cleaning device even when the handle of the cleaning device is subjected to a large external force.

[0124] In one embodiment, referring to Figure 1 As shown, the cleaning device body 20 includes an upper shell 22 and a bottom shell 21 that are detachably connected to each other. A water pump assembly mounting portion (not shown in the figure) is provided between the end of the upper shell 22 near the cleaning device handle 21A and the end of the bottom shell 21 near the cleaning device handle 21A. The water pump assembly 10 is mounted on the water pump assembly mounting portion, and the power connection end of the water pump assembly 10 is electrically connected to the energy unit 50 that is clamped to the cleaning device handle 21A. The docking assembly 50A of the energy unit achieves a stable electrical connection between the water pump assembly 10 and the energy unit 50. The front end of the bottom shell 21 is provided with two clamping walls (not shown in the figure) that clamp the cleaning roller 30. The cleaning roller 30 can rotate stably between the two clamping walls and elastically abut the surface to be cleaned with the portion that exceeds the two clamping walls to continuously clean the surface to be cleaned.

[0125] In one embodiment, referring to Figure 1 As shown, the cleaning device may further include a water tank 40. A water tank mounting portion (not shown) is provided on the side of the upper shell 22 away from the bottom shell 21, and the water tank mounting portion is located axially to the side of the water pump assembly mounting portion. The cleaning roller 30 is provided at the end of the cleaning device body 20 away from the handle 21A. The water tank 40 is mounted on the water tank mounting portion and is respectively connected to the water pump assembly 10 and the cleaning roller 30. Specifically, the water tank 40 may include a clean water tank (not shown in the figure) and a dirty water tank (not shown in the figure). The water pump assembly 10 may include a suction pump (not shown in the figure) and a delivery pump (not shown in the figure). The suction pump is used to draw dirty water from the cleaning roller 30 during the process of scrubbing the surface to be cleaned into the dirty water tank, and the delivery pump is used to deliver clean water in the clean water tank to the cleaning roller 30.

[0126] In one embodiment, referring to Figure 1 As shown, the cleaning device may further include a water tank locking mechanism (not shown in the figure) arranged on the upper shell 22. After the water tank 40 is installed on the water tank mounting portion, the water tank locking mechanism can lock the water tank 40 to the water tank mounting portion to prevent the water tank 40 from loosening or detaching from the upper shell 22 during the cleaning process of the cleaning device.

[0127] The cleaning device provided by the present invention realizes convenient power supply by providing a detachable energy unit 50, and realizes stable installation of the energy unit 50 by providing a shell 501, an elastic member 510 and a button 503, thereby avoiding the occurrence of electrical connection failure; by reasonably installing the water pump assembly 10, the water tank 40 and the cleaning roller 30, while realizing the cleaning function of the cleaning device, the structure of the cleaning device is made compact, thereby improving the convenience and portability of use.

[0128] The present invention provides a cleaning device handle of an embodiment, wherein the housing of the cleaning device extends toward the end to form a handle with an open end and a hollow straight cylindrical shape, and the energy unit and the handle are tightly connected by the use of an elastic member and a button; a power supply assembly is arranged to extend out of the housing of the energy unit and electrically connected to the water pump assembly, thereby realizing a detachable electrical connection between the cleaning device handle and the cleaning device; the power supply assembly is arranged in the housing of the energy unit, and a guide frame is provided to seal the power supply assembly against the housing of the energy unit, thereby realizing a secure installation of the power supply assembly; through layer-by-layer assembly, the power supply assembly is tightly connected to other components of the energy unit, and the energy unit is firmly confined in the handle, thereby ensuring the stability of its electrical connection with the water pump assembly; the handle is extended from the housing of the cleaning device to the end, therefore, compared with the existing cleaning device handle that is bent nearly 90 degrees, the convenience of holding is improved, and while ensuring the detachable electrical connection between the cleaning device handle and other components of the cleaning device, the compactness and stability of the structure are improved, and it can prevent the occurrence of electrical connection failure and the separation of the energy unit built into the cleaning device handle under impact.

[0129] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. The present disclosure is not limited to the precise structure described above and illustrated in the accompanying drawings, and various modifications and variations may be made without departing from its scope. The scope of the present disclosure is limited solely by the appended claims. Thus, to the extent such modifications and variations fall within the scope of the claims and their equivalents, the present disclosure is intended to include such modifications and variations.
