Description

Technical Field

[0001] This disclosure relates to the field of cleaning technology, and in particular to a cleaning system; this disclosure also relates to a charging component for use with electrical equipment, a cleaning device, and a tray. Background Technology

[0002] Currently, most household floor cleaners and other cleaning equipment use a charging tray. To charge, simply place the cleaning device on the tray; there's no need to plug or unplug the adapter, simplifying the charging process for users. The cleaner typically consists of a main body and a floor brush for cleaning the floor. The main body can rotate relative to the brush for easy operation.

[0003] When the cleaning machine is placed on the charging tray, the machine body may wobble to some extent relative to the floor brush, which may cause poor contact between the cleaning machine and the charging tray. In addition, after the cleaning machine has been used for a period of time, the body will wear down, and when placed on the charging tray, the body will tilt, resulting in poor contact between the body and the charging part of the tray, causing poor charging or failure to charge, which greatly reduces the user experience.

[0045] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0046] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0050] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0051] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0052] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0053] This disclosure provides a cleaning system including a cleaning device and a tray. The cleaning device can be a handheld cleaning device well-known to those skilled in the art, such as a washer or vacuum cleaner. The cleaning device may include a body and a floor brush assembly for cleaning work surfaces. The floor brush assembly is equipped with rollers, which are configured to rotate about an X-axis during operation. The cleaning device has a predetermined forward direction, and the X-axis is perpendicular to the forward direction of the cleaning device. The floor brush assembly is pivotally connected to the body and is configured to rotate relative to the body about the X-axis. During use, the floor brush assembly is in contact with the ground, and the user can rotate the body about the X-axis relative to the floor brush assembly to adjust the angle of the body relative to the floor brush assembly. After adjusting the body to a comfortable angle, cleaning can begin. For clarity and conciseness, the X-axis of the cleaning device is considered the left-right direction, and the body rotates about the X-axis in the up-down, forward-backward directions when cleaning the floor.

[0054] The tray is designed to hold cleaning equipment, which is charged and self-cleaned via the tray. The cleaning system also includes a charging assembly comprising a male charging connector and a female charging connector that mates with it. One of the male and female connectors is located on the machine body, and the other is located on the tray. First electrodes are positioned on opposite sides of the male charging connector along the X-axis; second electrodes are positioned on the female charging connector at corresponding positions. When the cleaning equipment is placed on the tray and the male and female charging connectors are engaged, the first and second electrodes contact and become conductive, allowing the tray to charge the cleaning equipment.

[0055] Because the brush assembly is supported on the tray, and the body assembly extends upwards at a predetermined angle relative to the brush assembly, when the body rotates relative to the brush assembly, its charging male and female connectors also tilt or wobble in that direction. Positioning the first and second electrodes on opposite sides along the X-axis ensures that the first and second electrodes remain in contact even when the body wobbles relative to the brush assembly, preventing poor contact that could affect charging.

[0056] In some embodiments of this disclosure, such as Figures 1 to 3 As shown, the cleaning system includes a cleaning device 1 and a tray 2. The cleaning device 1 includes a body 11 and a floor brush assembly 12. The floor brush assembly 12 is equipped with rollers 120, which are configured to rotate around an X-axis. The floor brush assembly 12 moves on the ground via the rollers 120. Two rollers 120 are provided, distributed along the X-axis, and the axis of rotation of the rollers 120 is denoted as the axis of the X-axis. When a user holds the cleaning device 1 to clean a work surface, the rollers 120 can rotate on the ground along the X-axis, thereby assisting the floor brush assembly 12 in reciprocating movement. The body 11 and the floor brush assembly 12 are movably connected, allowing the body 11 to rotate relative to the floor brush assembly 12 at least along the X-axis. In addition to rotating along the X-axis, the body 11 can also move in other directions relative to the floor brush assembly 12, such as rotating around the Y-axis perpendicular to the X-axis, or the body 11 and the floor brush assembly 12 can be universally connected, so that the body 11 can rotate relative to the floor brush assembly 12 in any direction.

[0057] The cleaning device 1 can be placed on the tray 2 for charging. The cleaning system also includes a charging assembly, which includes a male charging connector 3 and a female charging connector 4 that can be mated together. The male charging connector 3 is located on the tray 2, and the female charging connector 4 is located on the body 11; or the male charging connector 3 is located on the body 11, and the female charging connector 4 is located on the tray 2. When the cleaning device 1 is placed on the tray 2, the male charging connector 3 can mate with the female charging connector 4, thereby charging the body 11 through the tray 2.

[0058] The male charging connector 3 is provided with a first electrode 31, and at least two first electrode 31s may be provided, at least one of which is a positive electrode and at least one of which is a negative electrode. The at least two first electrode 31s are arranged in the X-axis direction and are located on opposite sides of the male charging connector 3. The female charging connector 4 is structured to match the male charging connector 3, i.e., the female charging connector 4 has an inner cavity, in which at least one second electrode 41 as a positive electrode and at least one second electrode 41 as a negative electrode are provided. The at least two second electrode 41s are distributed in the X-axis direction and are located on opposite sides of the inner cavity of the female charging connector 4, so that the positions of the two second electrode 41s correspond to the positions of the two first electrode 31s respectively. When the male charging connector 3 and the female charging connector 4 are engaged, i.e., when the male charging connector 3 is inserted into the inner cavity of the female charging connector 4, the first electrode 31 on the outside of the male charging connector 3 contacts and conducts electricity with the corresponding second electrode 41 in the inner cavity of the female charging connector 4, thereby charging the cleaning device 1 through the tray 2. Both the first electrode 31 and the second electrode 41 are made of conductive materials, which is common knowledge to those skilled in the art and will not be described in detail here.

[0059] When the cleaning device 1 tilts or shakes on the tray 2, because the direction of the shaking of the body 11 is perpendicular to the arrangement direction of the electrode plates, the first and second electrode plates remain in contact during the shaking, preventing them from separating and ensuring the charging effect. In a specific embodiment of this disclosure, for example, if the X-axis direction is left-right, since the body 11 and the floor brush assembly 12 can rotate relative to each other around the X-axis, the body 11 will shake back and forth relative to the floor brush assembly 12. When the floor brush assembly 12 is supported on the tray 2, the first electrode plates 31 and second electrode plates 41 on the left and right sides of the body 11 will remain in contact during the back-and-forth shaking relative to the floor brush assembly 12, thus ensuring the charging effect.

[0060] In another embodiment of this disclosure, the rest is the same as the above embodiment, except that at least two first electrode plates 31 are arranged in a direction perpendicular to the X-axis and are located on the front and rear sides of the charging male connector 3, respectively; one first electrode plate 31 faces the forward direction of the cleaning device, and the other first electrode plate 31 faces the backward direction of the cleaning device. Correspondingly, the charging female connector 4 is provided with two second electrode plates 41 in a direction perpendicular to the X-axis and is located on the front and rear sides of the charging female connector 4 slot, respectively; one second electrode plate 41 faces the forward direction of the cleaning device, and the other second electrode plate 41 faces the backward direction of the cleaning device. When the charging male connector 3 and the charging female connector 4 are connected, the first electrode plate 31 and the second electrode plate 41 are paired and electrically connected. In this embodiment, because the charging male connector 3 or the charging female connector 4 is provided with an elastic device, even if the cleaning device shakes in the forward or backward direction, a good electrical connection can be ensured between the charging male connector 3 and the charging female connector 4.

[0061] In another embodiment of this disclosure, the rest is the same as the above embodiment, except that at least two first electrode plates 31 are arranged in the X-axis direction and are respectively located on the front side of the charging male connector 3; that is, at least two first electrode plates 31 are arranged at intervals on the front side of the charging male connector 3. Correspondingly, at least two second electrode plates 41 are arranged in the X-axis direction and are respectively located on the front side of the charging female connector 4 slot; that is, at least two second electrode plates 41 are arranged at intervals on the front side of the charging female connector 4. When the charging male connector 3 and the charging female connector 4 are connected, at least two first electrode plates 31 and at least two second electrode plates 41 are paired and electrically connected. The first electrode plates 31 and the second electrode plates 41 are arranged on the same side, which solves the problem of poor electrical connection caused by the shaking of the cleaning equipment on the tray, and also solves the problem of poor electrical connection caused by rust and impurities between multiple electrode plates.

[0062] In another embodiment of this disclosure, the rest is the same as the above embodiment, except that at least two first electrode plates 31 are arranged in the X-axis direction and are respectively located on the rear side of the charging male connector 3; that is, at least two first electrode plates 31 are arranged at intervals on the rear side of the charging male connector 3. Correspondingly, at least two second electrode plates 41 are arranged in the X-axis direction and are respectively located on the rear side of the charging female connector 4 slot; that is, at least two second electrode plates 41 are arranged at intervals on the rear side of the charging female connector 4. When the charging male connector 3 and the charging female connector 4 are connected, at least two first electrode plates 31 and at least two second electrode plates 41 are paired and electrically connected. The first electrode plates 31 and the second electrode plates 41 are arranged on the same side and are respectively located on the rear side of the charging male connector 3 and the charging female connector 4, ensuring the stability of the electrical connection between the electrode plates. When the cleaning device is placed on the tray, the cleaning device is tilted at a predetermined angle towards the forward direction, for example, 5 to 20 degrees, to make the cleaning device stand stably on the tray. Therefore, both the first electrode 31 and the second electrode 41 are located on the rear side, while the cleaning device stands tilted forward on the tray, ensuring a stable electrical connection between the electrodes. In one embodiment of this disclosure, the charging female connector 4 has a slot, and the charging male connector 3 can be inserted into the charging female connector 4. The second electrode 41 is disposed in the slot of the charging female connector 4. After the charging male connector 3 is inserted into the slot, the first electrode 31 and the second electrode 41 located on the same side engage together.

[0063] In some embodiments of this disclosure, such as Figure 4 , Figure 5 As shown, the male charging connector 3 is equipped with an elastic device 32. The elastic device 32 is configured to drive the first electrode 31 to pre-press onto the corresponding second electrode 41, ensuring that the male charging connector 3 and the female charging connector 4 remain in contact after mating, thus avoiding poor contact. The elastic device 32 can be configured to act on both first electrodes 31 simultaneously, or different elastic devices 32 can be used to act on the two first electrodes 31 respectively. The elastic device 32 includes, but is not limited to, springs, sheet springs, elastic blocks, etc.

[0064] In some embodiments of this disclosure, such as Figure 5 As shown, the charging male connector 3 includes a housing 33, which has a receiving cavity 330 inside. Openings 331 communicating with the receiving cavity 330 are respectively provided on opposite sides of the housing 33. The first electrode 31 is configured to at least partially extend out of the opening 331 of the receiving cavity 330 under the elastic force of the elastic device 32, and to at least partially retract into the receiving cavity 330 when squeezed by the second electrode 41, overcoming the elastic force of the elastic device 32.

[0065] The housing 33 of the male charging connector 3 and the slot of the female charging connector 4 can be configured to be in clearance fit. After the housing 33 extends into the slot, it has a certain amount of room to move. The elastic device 32 drives the first electrode 31 to pre-press on the second electrode 41 in the slot, which enables the male charging connector 3 and the female charging connector 4 to fit tightly.

[0066] In one embodiment of this disclosure, such as Figure 5 As shown, the elastic device 32 is disposed in the receiving cavity 330. The opposite ends of the elastic device 32 respectively cooperate with the two first pole pieces 31, thereby allowing the elastic device 32 to push the two first pole pieces 31 to move in opposite directions, so that the two first pole pieces 31 at least partially extend out of their corresponding openings 331. The elastic device 32 can be located between the two first pole pieces 31, providing elastic forces in opposite directions to the two first pole pieces 31. For example, the elastic device 32 can be a compression spring, with its two ends connected to the two first pole pieces 31 respectively, so that the force of the elastic device 32 can act on both first pole pieces 31 simultaneously.

[0067] In another embodiment of this disclosure, two elastic devices 32 may be provided, and both are provided in the receiving cavity 330 of the housing 33. The two elastic devices 32 respectively cooperate with the two first pole pieces 31 and push the two first pole pieces 31 to move in opposite directions.

[0068] In one embodiment of this disclosure, such as Figure 4 , Figure 5 As shown, the housing 33's receiving cavity 330 also includes a movable block 34 movably connected to it. The first electrode 31 is fixed to the movable block 34 and located on the end face of the movable block 34 extending out of the opening 331. The two movable blocks 34 can be configured to guide and engage with the receiving cavity 330, enabling them to move in opposite directions along the receiving cavity 330. The first electrode 31 moves with the movable block 34 in the direction of extending out or retracting from the opening 331. The elastic device 32 in the receiving cavity 330 can engage with the movable block 34. Specifically, the movable block 34 is made of insulating material, and the first electrode 31 can be connected to the movable block 34 by bonding, snap-fitting, screw connection, or other methods well known to those skilled in the art. The elastic device 32 is disposed between the two movable blocks 34, with its opposite ends engaging with the two movable blocks 34 respectively, driving the two movable blocks 34 to move in opposite directions so that the two first electrodes 31 at least partially extend out of the opening 331 of the receiving cavity 330.

[0069] In one specific embodiment, the elastic device 32 is a compression spring connected between two movable blocks 34. Each movable block 34 has a spring seat 35 on the side closest to the elastic device 32, and the two ends of the compression spring abut against the spring seats 35 of the two movable blocks 34 respectively.

[0070] In one embodiment of this disclosure, such as Figure 5 As shown, a limiting structure can be provided on the movable block 34. This limiting structure cooperates with the housing 33 to prevent the movable block 34 from detaching from the receiving cavity 330 of the housing 33. In one specific embodiment, stepped grooves 341 can be provided on the side of each of the two movable blocks 34 closest to the opening of the receiving cavity. The stepped grooves 341 can engage with the inner edge of the opening 331 of the receiving cavity 330. The elastic device 32 can pre-press the stepped grooves 341 of the two movable blocks 34 onto the corresponding edges of the receiving cavity openings. When the two movable blocks 34 engage with the edges of the openings 331 of the receiving cavity 330, both first pole pieces 31 extend at least partially beyond the openings 331 of the receiving cavity 330. When the first pole pieces 31 move into the receiving cavity 330 under the action of the second pole piece 41, overcoming the action of the elastic device 32, the stepped grooves 341 of the movable blocks 34 move along the receiving cavity, leaving the edge of the opening 331. In other specific embodiments, the limiting structure can be a flange, a protrusion, or other structure that can cooperate with the inner or outer edge of the cavity opening, or other conventional limiting structures, as long as they can prevent the movable block 34 from disengaging from the cavity 330.

[0071] In one embodiment of this disclosure, such as Figure 5 As shown, a partition 3301 is provided inside the receiving cavity 330. The partition 3301 extends inward from the inner wall of the receiving cavity to between the two movable blocks 34, and avoids the elastic device 32. When the two movable blocks 34 are squeezed and move into the receiving cavity 330 by overcoming the force of the elastic device 32, the partition 3301 can interfere with the movable blocks 34 and restrict the movement position of the movable blocks 34.

[0072] In one embodiment of this disclosure, such as Figure 5 As shown, the end face of the movable block 34 extending from the opening 331 is constructed as an inclined guide surface, and the first pole piece 31 is disposed on the guide surface. Specifically, refer to... Figure 5 From a certain perspective, the guide surfaces of the two movable blocks 34 gradually approach each other from the end near the tray 2 to the end away from the tray 2. The first electrode 31 is also set to be inclined along the corresponding guide surface, which is conducive to the first electrode 31 smoothly entering the slot of the charging female head 4 and cooperating with the second electrode 41.

[0073] To facilitate the connection and mating of the male charging connector 3 and the female charging connector 4, in some embodiments of this disclosure, such as... Figure 6As shown, the male charging connector 3 is constructed with a wedge-shaped structure, meaning that the size of the free end of the male charging connector 3 is smaller than the size of the end connecting the male charging connector 3 to the tray 2. The female charging connector 4 is constructed with a shape adapted to the male charging connector 3, meaning that the size of the slot of the female charging connector 4 gradually decreases from the opening to the bottom of the slot, and the end size of the housing 33 of the male charging connector 3 is smaller, which facilitates smooth insertion into the slot with a larger opening, and also facilitates the smooth entry of the first electrode 31 protruding from the opening 331 into the slot.

[0074] In one embodiment of this disclosure, the tilt angle of the guide surface of the movable block 34 can be consistent with the tilt angle of the side wall of the charging male connector 3, which is not only aesthetically pleasing, but also facilitates the mating of the charging male connector 3 and the charging female connector 4.

[0075] In some other embodiments of this disclosure, the male charging connector 3 may be configured as a conical structure, an arc structure, etc., which can facilitate the insertion and mating of the male charging connector 3 and the female charging connector 4. These will not be described in detail here.

[0076] In some embodiments of this disclosure, such as Figure 4 As shown, two second electrode plates 41 are disposed in the slot of the female charging connector 4 and are located on the inner walls of opposite sides of the slot. The slot structure is configured to fit the wedge-shaped male charging connector 3. Both the two first electrode plates 31 and the two second electrode plates 41 are inclined, and the first electrode plates 31 and the second electrode plates 41 located on the same side are inclined in the same direction, so they can cooperate with each other.

[0077] In some embodiments of this disclosure, such as Figure 4 As shown, the casing 11 includes a housing 110, which forms a slot for the charging female connector 4. The charging female connector 4 also includes a fixing bracket for fixing the second electrode 41. A decorative cover 111 is also provided on the outer side of the housing 110. The decorative cover 111 can press the fixing bracket against the edge of the slot, and the fixing bracket is confined between the housing 110 and the decorative cover 111. The fixing bracket is made of insulating material, and the second electrode 41 can be connected to the fixing bracket by means of bonding, snap-fit, screw connection, etc. The decorative cover 111 can be fixed to the housing 110 by means of screw connection, snap-fit ​​connection, plug-in connection, etc.

[0078] In some embodiments of this disclosure, such as Figure 7As shown, a protruding structure 311 is provided on the end face of the first electrode 31 that mates with the second electrode 41. The protruding structure 311 is configured to mate with the second electrode 41. The protruding structure 311 can be a hemispherical structure or a rib structure. The number of protruding structures 311 is at least one. In one specific embodiment, three protruding structures 311 are provided and distributed in a triangular structure. The three protruding structures 311 can contact the second electrode 41, ensuring the stability of the connection and preventing the first electrode 31 and the second electrode 41 from being unable to contact each other and causing the charging circuit to be broken if foreign objects enter between them.

[0079] In some embodiments of this disclosure, such as Figure 1 , Figure 2 As shown, the tray 2 includes a base 21 for cooperating with the floor brush assembly 12, and a positioning seat 22 disposed on the base 21. A female charging connector 4 is disposed on the positioning seat 22 and configured to mate with a male charging connector 3 on the body 11; alternatively, a male charging connector 3 is disposed on the positioning seat 22 and configured to mate with a female charging connector 4 on the body 11. Specifically, the base 21 may have grooves and / or protrusions that mate with the floor brush assembly 12 to ensure the stability of the mating between the base 21 and the floor brush assembly 12. The positioning seat 22 is higher than the base 21 and extends upward from the position where it connects to the base 21, thereby providing a certain degree of support for the body 11.

[0080] In some embodiments of this disclosure, such as Figure 6 , Figure 7 As shown, the positioning base 22 is also provided with a limiting part 221, which is configured to prevent the fuselage 11 from rotating in the X-axis direction. The limiting part 221 can be configured to block the front and / or rear sides of the fuselage 11, and the fuselage 11 can lean against the limiting part 221 to prevent it from tilting back and forth in the X-axis direction.

[0081] In one embodiment of this disclosure, such as Figure 7 As shown, the charging female connector 4 or charging male connector 3 on the positioning base 22 is configured to extend vertically upwards or inclined upwards. The cleaning device 1 is placed on the tray 2 from top to bottom, and the charging male connector 3 and charging female connector 4 can be connected together in an up-and-down manner for charging. Only when the main body 11 is lifted upwards can the charging male connector 3 and charging female connector 4 be separated from each other, ending the charging process.

[0082] In one embodiment of this disclosure, such as Figure 6 , Figure 7As shown, the limiting portion 221 of the positioning seat 22 forms a semi-open groove, the wall of which is constructed as an inclined surface 2210. At least a portion of the body 11 is confined within the gap between the inclined surface 2210 and the charging male connector 3 or charging female connector 4 on the positioning seat 22. The semi-open groove provides a larger support surface for the body 11, enabling more stable support. Specifically, the inner side of the groove is constructed as an inclined surface 2210, which gradually slopes outward from the bottom end near the positioning seat 22 to the top end away from the positioning seat 22, making it easier for the body 11 to fit into the groove from top to bottom.

[0083] Reference Figure 3 , Figure 7 In the embodiment shown, the inclined surface 2210 can be configured to fit the shape of the fuselage 11. A mating part 112 corresponding to the position of the inclined surface 2210 can be provided on the fuselage 11, and the mating part 112 is configured to fit the inclined surface 2210.

[0084] In one specific embodiment of this disclosure, reference is made to Figure 6 , Figure 7 As shown, the charging male connector 3 is mounted on the positioning seat 22. The limiting part 221 extends on both sides of the tray in the X-axis direction (towards the charging male connector 3) to form a C-shaped semi-open groove with the opening facing its front side. This groove can support the rear and left and right sides of the body 11 and prevent the body 11 from tilting to the left or right or rear relative to the floor brush assembly 12.

[0085] In one specific embodiment of this disclosure, such as Figure 6 , Figure 7 As shown, the male charging connector 3 extends vertically upwards or tilted upwards, and the body 11 can fit on the positioning seat 22 from top to bottom. The female charging connector 4 of the body 11 is inserted into the male charging connector 3 extending approximately vertically below. In addition, the outer wall of the corresponding position of the body 11 can abut against the wall surface of the limiting part 221, thereby providing a certain degree of support for the body 11.

[0086] This disclosure also discloses a charging assembly that can be applied to cleaning equipment or other electrical devices requiring charging. The charging assembly includes a male charging connector and a female charging connector, which can cooperate with each other for charging. At least two first electrodes are respectively disposed on opposite sides of the male charging connector along the X-axis; at least two second electrodes are respectively disposed on the female charging connector at corresponding positions. When the male charging connector rotates relative to the female charging connector around the X-axis, the corresponding first and second electrodes remain in contact, without affecting charging. The specific structure and principle of this charging assembly can be found in the aforementioned cleaning system, and will not be described in detail here.

[0087] This disclosure also provides a cleaning device, which can be a handheld cleaning device well known to those skilled in the art, such as a washer or vacuum cleaner. The cleaning device is configured to be placed on a tray. The cleaning device includes a body and a floor brush assembly with wheels configured to rotate about an X-axis.

[0096] The technical solution adopted by this invention will be described below in conjunction with specific application scenarios to aid understanding. In the application scenarios below, a floor scrubber is used as an example of the cleaning equipment.

[0097] Application Scenario 1

[0098] In the cleaning system, the male charging connector 3 is mounted on the positioning seat 22 of the tray 2, and the female charging connector 4 is mounted on the machine body 11. The floor scrubber is placed on the tray 2 from top to bottom. The floor brush assembly 12 is fitted onto the base 21 of the tray 2, and the machine body 11 is fitted onto the positioning seat 22. The limiting part 221 supports the rear side of the machine body 11. After the machine body 11 is fitted with the positioning seat 22, its female charging connector 4 can be inserted and engaged with the male charging connector 3 on the positioning seat 22. The direction of the male charging connector 3 is consistent with the direction in which the machine body 11 is supported by the limiting part 221. Two first electrodes 31 on the male charging connector 3 are located on the left and right sides and extend out of the opening 331 of the receiving cavity 330 under the action of the elastic device 32. After the male charging connector 3 is inserted into the slot of the female charging connector 4, it is squeezed by the second electrode 41, thereby causing the first electrode 31 to retract at least partially into the receiving cavity 330. Thus, under the action of the elastic device 32, the first electrode 31 is pre-pressed onto the corresponding second electrode 41, so that the two are connected and conducting. When the body 11 shakes back and forth, the first electrode 31 and the second electrode 41 located on the left and right sides will also move relative to each other, but it can be ensured that the first electrode 31 and the second electrode 41 can always be in contact without affecting charging.

[0099] Application Scenario 2

[0100] In the cleaning system, the female charging connector 4 is mounted on the positioning seat 22 of the tray 2, and the male charging connector 3 is mounted on the body 11. The floor scrubber is placed on the tray 2 from top to bottom. The floor brush assembly 12 is fitted onto the base 21 of the tray 2, and the body 11 is fitted onto the positioning seat 22. The limiting part 221 supports the rear side of the body 11. After the body 11 is fitted with the positioning seat 22, its male charging connector 3 can be inserted into the female charging connector 4 on the positioning seat 22. The direction of the female charging connector 4 slot is consistent with the direction in which the body 11 is supported by the limiting part 221. Two first electrode plates 31 on the male charging connector 3 are located on the left and right sides, and extend out of the opening of the receiving cavity 330 under the action of the elastic device 32. After the male charging connector 3 is inserted into the slot of the female charging connector 4, it is pressed by the second electrode plate 41, causing the first electrode plate 31 to at least partially retract into the receiving cavity 330. Under the force of the elastic device 32, the first electrode plate 31 is pre-pressed onto the corresponding second electrode plate 41, ensuring the charging effect.
