Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to an energy unit and a cleaning device equipped with the energy unit. Background Art

[0002] Traditional car washing devices often occupy a space that can accommodate at least one whole car. The car washing process involves spraying clean water and cleaning liquid on the body and scrubbing and rinsing the body with a large mechanical roller. The entire car washing device is large in size, consumes water and electricity, and has a loud operating noise. In recent years, with the popularization of floor scrubbers, portable car scrubbing tools have evolved from the "water-dust circulation" floor scrubbers. The motor of the portable car scrubbing tool drives the cleaning cylinder to wipe the body. The portable cleaning device is also equipped with a water supply system and a sink to clean the cleaning cylinder, thereby cleaning the body. Because traditional car washing devices consume water and electricity and have a loud operating noise, portable car scrubbing tools are becoming more and more popular among consumers.

[0003] The handles of some existing portable cleaning devices have batteries, display panels, control panels, etc., and can be quickly separated from the body. However, some existing cleaning device handles are set at an angle of nearly 90° to the body, which often makes the grip feel poor in actual use; the battery and other components of some cleaning device handles are not tightly connected to the handle housing and other parts of the cleaning device; and the electrical connection between the handle and the body is prone to failure when the handle is subjected to a large external force impact.

[0004] The charging heads of some existing portable cleaning devices are set on the device or on the handle. 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 exposure to sunlight on a hot summer day, it is easy to cause thermal runaway of the charging process and cause a fire. Summary of the invention

[0079] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0080] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "far", "near", "front", "back" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0081] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0082] The inventors have found that the handles of existing portable cleaning devices have a poor grip feel, and when the handles are subjected to a large external impact, electrical connection failure between the handles and the body is likely to occur.

[0083] Based on this, the present invention provides a cleaning device handle and a cleaning device, which are described in detail below through specific embodiments.

[0084] In a 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 with 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 of the 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, and the docking end cover 502 is detachably connected to the opening of the 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; an opening is provided at one end of the snap-in assembly 50C away from the power supply assembly 504, and the other end seals the power supply assembly 504 in the housing 501, and the outer edge of the snap-in assembly 50C can be snap-fitted 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 snap-fitted with the handle 21A, the output port is electrically connected to the water pump assembly 10 in the cleaning device, and 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.

[0085] Specifically, 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 connection with the shell 501 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 housing 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 shown in the drawing).

[0086] 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 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 to avoid a short circuit.

[0087] 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 power supply assembly of the energy unit is electrically connected to the water pump assembly through the docking assembly in the energy unit, so as to realize the 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 arranged to seal the power supply assembly in the housing of the energy unit, so as to realize the firm 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, so as to ensure 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 bent nearly 90 degrees, the convenience of holding is improved. Moreover, while ensuring that the cleaning device handle is detachably electrically connected to other parts of the cleaning device, because 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 it more difficult for the energy unit to loosen from the handle, and preventing the energy unit from detaching from the cleaning device handle under the action of impact and causing electrical connection failure.

[0088] The energy unit provided by the present invention has a charging port arranged on a docking end cover which 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.

[0089] 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 , Fig. 9 , Fig.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).

[0090] Specifically, Figure 2 , Figure 5 , Figure 8 , Fig. 9 , Fig.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.

[0091] The guide ribs on the inner wall of the handle 21A can cooperate with the guide grooves, and the guide ribs can limit the guide grooves in the circumferential direction, 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 is butted against the end of the guide groove, the guide rib slides along the guide groove until the clamping portion 503b of the button 503 is clamped 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 have the function of identifying the installation direction. For example, three guide grooves Q are set on one side and two guide grooves P are set on the other side. The installation direction can be determined by the number of guide grooves, thereby ensuring installation efficiency.

[0092] In one or some alternative embodiments, 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 that passes 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 of the docking end cover 502 and the docking assembly fixing hole 5012, the docking connection between the docking end cover 502 and the housing 501 can be achieved, so as to achieve the blocking of the opening end of the housing 501 by the docking assembly 50A.

[0093] In one or some alternative embodiments, Figures 6 to 9 , Fig.14 As shown, the housing 501 and the snap-on assembly 50C are provided with a snap-on groove 5011, a wire hole 501c, a bracket fixing hole 5013 and a guide rib 5014 at the joint position. 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 to 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 for guiding and positioning when the bracket 505 of the snap-on assembly 50C is installed at the open end of the housing 501.

[0094] 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.

[0095] Specifically, Figures 1 to 9 As shown, the clamping assembly 50C is cylindrical with one end smaller than the other, and the outer surface of the cylindrical shape is provided with at least one step (not shown in the figure). Figure 1As shown, the large diameter outer surface of the clamping assembly 50C (not marked in the figure) 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 figure) 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, the outer surfaces of the energy unit and the handle are completely smooth after the energy unit is clamped 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 hand 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 step, so that the small diameter outer surface of the clamping assembly is easier to clamp with the inner surface of the handle. If multiple layers of step difference steps 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 the 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 while also making the handle 21A and the housing 501 of the energy unit 50 slide and engage with each other under the positive pressure of the user's hand, thereby increasing the relative sliding friction between the two, so that when the handle of the cleaning device is subjected to a large external force impact, 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-on assembly 50C is only exposed on the outer surface of the handle 21A at the very end of the handle 21A, which makes it easy for the user to directly press the button 503 on the outer surface of the snap-on assembly 50C to release the snap-on assembly 50C from the handle 21A, allowing the user to pull out the entire energy unit 50 quickly and conveniently.

[0096] In one or some alternative embodiments, 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 outwardly to have a positioning wire tube 505c for blocking the housing, as shown in FIG. Figure 3 , Figure 4As shown, the positioning wire tube 505c extends into the wire hole 501c, and a sealing ring (not shown in the figure) is clamped on the positioning wire tube 505c to achieve sealing between the positioning wire tube 505c and the wire hole 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, respectively, with a guide column (a first guide column 505b1, a second guide column 505b2); the button 503 blocks the clamping groove 5011, and the button The key 503 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 key 503 and is disposed in the guide columns (505b1, 505b2) to drive the key 503 to move linearly along the axis of the guide column; a wire harness 509a is also provided in the energy unit 50 to electrically connect the charging control component 506, and the other end of the wire 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 the positioning wire tube outwardly with one end pointing to the docking end cover to seal the power supply component in the housing of the energy unit, and at the same time, the bracket can extend two guide columns outwardly pointing to the inner wall of the handle to limit the key to move only in the axial direction of the guide column, so that the clamping component 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.

[0097] Specifically, 10 to Fig.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 on 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 accurately slide into the housing 501. When assembling the clamping assembly 50C, the bracket 505 needs to be accurately slid into the housing 501 through the guide rib 5054 by using the bracket fixing guide groove 5014, and then 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, and then the display panel 509 is fixed to the bracket 505 through the display panel fixing hole 5052.

[0098] Specifically, Figure 2 , Figure 3 , Figures 5 to 9As shown, a pair of snap-in grooves 5011 are arranged on the side walls of the housing 501; the bracket 505 blocks the opening of the housing 501, and the bracket 505 has guide columns (505b1, 505b2) extending radially outward; the elastic member 510 is installed in the guide columns (505b1, 505b2), the button 503 extends into the guide columns (505b1, 505b2) and the snap-in grooves 5011 to abut against the elastic member 510, and the button 503 is snap-fitted to the opening of the handle 21A.

[0099] In one or some alternative embodiments, Fig.10 , Fig.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 column (505b1, 505b2) are perpendicular to the axis of the bracket and the axis of the guide column, and each has a Z-shaped reinforcing rib (a first reinforcing rib 505a1, a second reinforcing rib 505a2) extending outward, and the two reinforcing ribs (505a1, 505a2) are symmetrical around the center of the axis of the bracket, and the reinforcing ribs include an upper horizontal edge, a vertical edge, and a lower horizontal edge (not shown in the drawings).

[0100] Further, such as Fig.10 , Fig.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.

[0101] In one or some alternative embodiments, Figure 2 , Figure 3 As shown, the outer surface of the button 503 is flush with the surface of the step difference, and 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 assembly 50C, and the outer surface of the clamping portion 503b is flush with the outer surface of the small diameter of the clamping assembly 50C, and the clamping portion 503b is provided with a clamping tooth protruding outward (not marked in the drawings), 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 remind the user that the energy unit 50 can be separated from the handle 21A by pressing the button 503.

[0102] In this embodiment, refer to Figures 1 to 9 As shown, the energy unit 50 is clamped with the handle 21A through the button 503. Since the button 503 abuts against the elastic member 510, the clamping 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, and when the housing 501 is inserted into the handle 21A, the clamping portion 503b is clamped 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, making it easier to extract 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 handle of the cleaning device is held, the button 503 will not be subjected to force alone, and thus will not be pressed by mistake.

[0103] In one or some alternative embodiments, Fig.13 As shown, at least one guide limit tooth 503c extends from one side of the button portion 503a close to the bracket 505, and the guide limit tooth 503c can only move along the axial direction of the guide column under the restriction of the limit hole. Further, a limit hook (not shown in the figure) is also provided on the guide limit tooth to prevent the button 503 from being bounced off the bracket 505 under the elastic force of the elastic member 510.

[0104] Specifically, Fig.13 As shown, the first guide limit tooth 503c1 and the second guide limit tooth 503c2 extend from one side of the button portion 503a close to the bracket 505, and the two guide limit teeth are respectively arranged on both sides of the guide through column (505b1, 505b2) and are arranged one in front of the other in the axial direction of the bracket, and the two guide limit teeth can slide linearly in the limit hole. Figures 6 to 9 , Fig.13 As shown, the two buttons 503 are injection molded by sharing the same mold. In other words, the two buttons are exactly the same. Since the Z-shaped reinforcing ribs on the two side walls of the bracket body 505a are completely symmetrically arranged along the axis of the guide column, the same button can be rotated 180 degrees to continue to press the guide limit teeth into the corresponding limit holes of the opposite guide column. Such a design of the centrally symmetrical Z-shaped reinforcing ribs and buttons can reduce the types and number of molds required for processing the clamping assembly 50C, and reduce the types of parts required for assembling the clamping assembly 50C.

[0105] In one or some alternative embodiments, Fig.13As shown, a guide column 503d is further extended from the side of the button portion 503a close to the bracket 505, and the guide column 503d can slide linearly in the guide through columns (505b1, 505b2). In this way, the pressure of the guide limit tooth 503c sliding linearly in the limit hole can be further reduced to prevent the user from pressing the button with uneven force or breaking the guide limit tooth 503c with excessive force when deviating from the axial direction of the guide through column, and further improve the overall service life of the clamping assembly 50C under the user's habit of repeatedly disassembling and assembling the energy unit 50.

[0106] The energy unit provided by the present invention is clamped with one end of the handle of the cleaning device through a clamping assembly. By arranging 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, the user 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.

[0107] In one or some alternative embodiments, 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, and the docking end cover 502 of the docking component 50A is provided with a plurality of through holes (not shown in the drawings), through which the output port and the charging port of the charging control component 506 can be accessed by external devices, and 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 shown in the drawings) of the water pump component 10.

[0108] Furthermore, a plurality of pin receiving holes (not shown in the drawings) are provided at the end of the docking end cover 502, and pins (not shown in the drawings) are provided in the pin receiving holes. The plurality of pins can be electrically connected to the positive power supply, negative power supply, 485 communication positive, and 485 communication negative (not shown in the drawings) of the output port, respectively, so that the output port at least partially extends out of the bottom hole (not shown in the drawings) of the pin receiving hole but does not protrude from the end face of the docking end cover 502. When the electrical connection between the pin and the power-taking electrode of the water pump assembly 10 is poor due to ablation or oxidation between the two, it is convenient for the user to replace and maintain the pins electrically connected to the output port in a timely manner. When the energy unit 50 is removed from the handle 21A of the cleaning device, since the plurality of pins electrically connected to the output port are all lower than the end face of the docking end cover 502, the user does not have to worry about the problem of the output port discharging to the outside.

[0109] In a specific 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 which are 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.

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 positive power supply, negative power supply, 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 positive input and negative input of the insulating protection board 506a, respectively, and the pins electrically connected to the positive power supply, negative power supply, 485 communication positive, and 485 communication negative on the charging control board 506b can be electrically connected to the positive power supply, negative power supply, 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 states to each other, and can be removed for charging when the power is insufficient. It should be noted that the output port described in this embodiment includes 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, and can be based on the I²C bus protocol and the ModBus communication protocol bus protocol. Therefore, the output port described in the present invention can also have other interfaces known to those skilled in the art that can achieve communication and interaction between multiple control boards, which are not specifically limited here.

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 out of the end cover 508a. Specifically, as Figure 8 , Fig. 9 , Fig.12 As shown, the outer edge of the display panel 509 is provided with a plurality of lamp beads, and the plurality of lamp beads are arranged in a ring shape. The display panel 509 and the silicone cover 507a are provided with a number of fixing through holes (not shown in the drawings) 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 on the opening end of the opening portion 505d of the bracket 505. The light guide ring 507b is arranged close to the silicone cover 507a and directly facing the annular lamp bead group. The end cover 508a seals the opening end of the opening portion 505d of the bracket 505 and sandwiches the light guide ring 507b between the end cover 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 cover 508a so that the user can easily identify the current working state of the cleaning device and the charging state of the current 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.

[0112] In one or some alternative embodiments, Figure 8 As shown, a docking seat 509b is provided on one side of the display panel 509 facing the bracket 505, and the docking harness 509a is electrically connected to the display panel 509 through the docking seat 509b.

[0113] In one or some alternative embodiments, Figure 8As shown, a touch switch 509c is provided on one side of the display panel 509 away from the bracket 505. The user can turn on / off the cleaning device, switch the working mode of the cleaning device, and turn on / off the voice function of the cleaning device by pressing the touch switch 509c. This embodiment does not specifically limit the duration, pressing frequency, number of consecutive pressings, and corresponding specific functions of the cleaning device when the user presses the touch switch 509c. All improved technical solutions that can be realized based on the above technical solutions by those skilled in the art using only one touch switch belong to the protection scope of this application.

[0115] Further, such as Fig. 9 As shown, the end cap 508a is provided with two hollow grooves 508a1, which are S-shaped, and the two S-shaped hollow grooves 508a1 are centrally symmetrically arranged. The two centrally symmetrical S-shaped hollow grooves 508a1 combine to form a nearly circular button area (not shown in the figure) with only two narrow edges attached on the end cap 508a, and the button area faces the touch switch and elastically abuts against it. In this way, the end cap 508a can have a wider range of material properties to choose from, without worrying that the end cap 508a is too hard to press the touch switch on the display panel 509 through the button area.

[0116] In one or some alternative embodiments, Fig. 9 , Fig.12 , Fig.13 As shown, the end cover 508a is provided with at least one end cover fixing hole 508a2, and the end cover fixing hole 508a2 corresponds to the fixing hole of the display panel 509 (not marked in the drawings) 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.

[0117] In one or some optional embodiments, the energy unit 50 further includes a buffer pad (not shown in the drawings) disposed between the bracket 505 and the power supply assembly 504. The buffer pad can buffer the power supply assembly 504 when the energy unit 50 or the cleaning device handle as a whole is impacted, and can help reduce vibration when the cleaning device is working, thereby protecting the power supply assembly 504, preventing the power supply assembly 504 from loosening or being damaged, and ensuring that the electrical connection between the power supply assembly 504 and the water pump assembly 10 is not prone to failure.

The handle 21A is cylindrical, and the handle 21A of the cleaning device handle is formed by extending from the end of the cleaning device body 20 of the cleaning device in a direction away from the cleaning roller 30, and 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 that can be detached from each other.

[0121] Compared with the existing cleaning devices with handles bent nearly 90 degrees, the cleaning device provided by the present invention has a longer handle and an energy unit, a slimmer power supply assembly, and a tighter connection between the power supply assembly and the housing, which not only improves the grip, but also improves the stability of the snap-fitting of the energy unit and the handle. In this way, when the user holds the handle of the cleaning device, he can directly hold the outer surface of the handle. While holding the handle tightly, the user also makes the relative sliding friction between the handle and the housing of the energy unit increase under the positive pressure of the user's hand, so that when the handle of the cleaning device is subjected to a large external force impact, the energy unit can still maintain a reliable electrical connection with the water pump assembly in the cleaning device.

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 installed on the water tank mounting portion and is connected to the water pump assembly 10 and the cleaning roller 30 respectively. 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), and 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 suck the dirty water in the process of the cleaning roller 30 scrubbing the surface to be cleaned into the dirty water tank, and the delivery pump is used to deliver the clean water in the clean water tank to the cleaning roller 30.

[0124] In a specific 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 on 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.
