[0053] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0054] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” generally includes at least two, and other quantifiers are similarly intended.

[0055] It should be understood that although the terms first, second, third, etc., may be used to describe embodiments of this disclosure, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, first may also be referred to as second without departing from the scope of embodiments of this disclosure, and similarly, second may also be referred to as first. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0056] It should be understood that the term "and / or" as used herein is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0057] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0059] Currently, cleaning devices using handle components, such as vacuum cleaners and mite removers, suffer from issues with handles that are positioned too far back and cannot be bent. This leads to instability in the device's center of gravity and makes it difficult for users to hold the device. Specifically, in related technologies, modules such as the battery, fan, and main control board of vacuum cleaners and mite removers are located below the handle. Since the front of the device also contains a dust cup, filter module, dust collection head, or brush head, the center of gravity and the position of the handle are not on the same vertical line. The center of gravity is in front of or behind the handle. From the perspective of leverage principles, this means that users have to exert a lot of force when holding the product. In addition to bearing the weight of the product itself, users also have to endure a bending torsional torque, resulting in a poor user experience. Prolonged operation can cause arm fatigue, and the large size makes it difficult to store.

[0060] Therefore, this disclosure provides a handle assembly and a cleaning device. The handle assembly includes: a guide rail extending along a first direction; a connecting slider slidably disposed on the guide rail; and a handheld portion detachably and / or foldably connected to the connecting slider, wherein the connecting slider and the guide rail have a locked state and an unlocked state.

[0061] The handle assembly and cleaning device disclosed herein are foldable or detachable for storage, occupying minimal space and making them ideal for small spaces in vehicles or homes. Furthermore, the handgrip is mounted on a guide rail, positioned above the product's center of gravity, minimizing or eliminating bending torque on the user and thus reducing the overall handgrip force on the user's arm, making cleaning easier. In addition, the handgrip can rotate relative to the guide rail, allowing the user to adjust it to a more suitable, effortless cleaning angle.

[0062] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0063] This disclosure provides a handle assembly 1000 and a cleaning device 3000. To more clearly describe the behavior of the cleaning device 3000, the following directions are defined based on the working direction of the cleaning device 3000: a front-to-back axis X, a lateral axis Y, and a central vertical axis Z. The direction opposite to the arrow on the front-to-back axis X, i.e., the forward movement direction of the cleaning device 3000 during normal operation, is labeled "forward," and the direction opposite to the arrow on the front-to-back axis X, i.e., the backward movement direction of the cleaning device 3000 during normal operation, is labeled "backward." The direction of the front-to-back axis X is the first direction. The lateral axis Y is essentially along the width of the cleaning device 3000. The direction of the arrow on the lateral axis Y is labeled "rightward," and the direction opposite to the arrow on the lateral axis Y is labeled "leftward." The direction of the left-to-right axis Y is the second direction. The vertical axis Z extends vertically along the self-moving device. The direction of the arrow on the vertical axis Z is labeled "upward," and the direction opposite to the arrow on the vertical axis Z is labeled "downward." The direction of the vertical axis Z is the third direction.

[0064] like Figure 1 As shown, the cleaning device 3000 includes a handle assembly 1000 and a cleaning device body 2000. The handle assembly 1000 is disposed on the cleaning device body 2000, and a portion of the handle assembly 1000 can rotate relative to the cleaning device body 2000. This allows the user to operate the cleaning device 3000 to clean the working surface when it is in operation, and reduces the space occupied by the cleaning device 3000 when it is not in operation, making it easier to store. The handle assembly 1000 is located above the center of gravity of the cleaning device body 2000, reducing the physical effort required by the user during use, decreasing the bending and torsional forces on the user's arm when using the cleaning device 3000, and reducing arm fatigue, thereby improving the user experience.

[0065] In some embodiments, such as Figure 1 , Figure 2 As shown, a first aspect of this disclosure provides a handle assembly 1000, which includes a guide rail 1120, a movable slider 1110, and a handheld portion 1200. The guide rail 1120 extends along a first direction and is configured to connect to a cleaning device body 2000. The handheld portion 1200 is movably connected to the movable slider 1110; specifically, the handheld portion 1200 is detachably connected to the movable slider, and the handheld portion 1200 can be assembled or detached from the movable slider as needed. The connecting slider 1110 is movably disposed on the guide rail 1120, and the connecting slider 1110 has dimensions that match the guide rail 1120, allowing the connecting slider 1110 to slide along the guide rail 1120.

[0066] In some embodiments, the connecting slider 1110 and the guide rail 1120 have locked and unlocked states. When the connecting slider 1110 and the guide rail 1120 are in the unlocked state, the connecting slider 1110 can freely move the entire handheld part 1200 along the guide rail 1120. When the connecting slider 1110 and the guide rail 1120 are in the locked state, the positions of the connecting slider 1110 and the guide rail 1120 are limited, and the connecting slider 1110 cannot freely move the entire handheld part 1200 along the guide rail 1120. In this case, the user can hold the handheld part 1200 to clean the operating surface using the cleaning device 3000.

[0067] In some embodiments, such as Figure 2As shown, the guide rail 1120 also includes a limiting hole 1101, which is disposed on the guide rail 1120 along a first direction. At least two limiting holes 1101 are provided on the guide rail 1120. The connecting slider 1110 can drive the handheld part 1200 to switch between at least two of the limiting holes 1101 to change the connection position between the handheld part 1200 and the guide rail 1120. That is, the at least two limiting holes 1101 are configured to allow the relative position between the handheld part 1200 and the guide rail 1120 to be variable.

[0068] In some embodiments, multiple limiting holes 1101 may be provided, and the multiple limiting holes 1101 are equally spaced along the first direction on the guide rail 1120, with the distance between two adjacent limiting holes 1101 being 5-20mm. Figure 2 As shown, the spacing between the limiting holes 1101 is approximately 6 mm. Because the spacing between the limiting holes 1101 is small, more limiting holes 1101 can be provided along the limited length of the guide rail 1120. When the contact angle between the cleaning device 3000 and the operating surface is different, the center of gravity of the cleaning device 3000 will also change accordingly. At this time, the position of the handle 1200 on the guide rail 1120 can be adjusted to adjust the positional relationship between the handle 1200 and the center of gravity, making it easier for the user to hold the cleaning device 3000.

[0069] In some embodiments, the limiting holes 1101 are concentrated on a portion of the guide rail 1120. Specifically, the limiting holes 1101 are concentrated on the front half of the guide rail 1120. Since the length of the handheld part 1200 needs to occupy a portion of the moving area on the guide rail 1120, this arrangement saves drilling time and improves processing efficiency in the production process. The rear half of the guide rail 1120 is a hole-free area, and the length of the hole-free area is approximately the length of the handheld part 1200 in the first direction.

[0070] In some embodiments, such as Figure 3As shown, the handheld part 1200 also includes a limit switch 1130, which is movably disposed on the connecting slider 1110 and has a locked position and an unlocked position. The limit switch 1130 is configured to be movably connected to the limiting hole 1101. Specifically, when the limit switch 1130 is in the locked position, at least a portion of the limit switch 1130 is located within the limiting hole 1101, thereby locking the handheld part 1200 to the guide rail 1120. When the limit switch 1130 is in the unlocked position, the limit switch 1130 disengages from the limiting hole 1101, and the handheld part 1200 can move freely relative to the guide rail 1120. When the limit switch 1130 is in the locked position, the user can hold the handheld part 1200 to clean the operating surface using the cleaning device 3000.

[0071] In some embodiments, such as Figure 3 As shown, the limit switch 1130 includes a locking assembly 1131 and an unlocking assembly 1132. The locking assembly 1131 is disposed inside the connecting slider 1110, and one end of the locking assembly 1131 has a matching shape and structure with the limiting hole 1101, configured to lock with the limiting hole 1101 to lock the connecting slider 1110 to the guide rail 1120. The unlocking assembly 1132 is disposed outside the connecting slider 1110 and configured to unlock the locking assembly 1131 from the limiting hole 1101. The housing of the connecting slider 1110 has an opening for the unlocking assembly 1132 to move, allowing the locking relationship between the locking assembly 1131 and the limiting hole 1101 to be changed by the movement of the unlocking assembly 1132 itself.

[0072] Specifically, when the limit switch 1130 is in the locked position, at least a portion of the latch assembly 1131 penetrates the limiting hole 1101 to lock, thereby preventing the connecting slider 1110 from moving on the guide rail 1120. When the limit switch 1130 is in the unlocked position, the unlocking assembly 1132 drives the latch assembly 1131 to move away from the guide rail 1120, so that the latch assembly 1131 disengages from the limiting hole 1101. At this time, the connecting slider 1110 can move freely relative to the guide rail 1120.

[0073] In some embodiments, the limit switch 1130 further includes a reset member 1140, which can be connected to the latching assembly 1131 and configured to latch the latching assembly 1131 to the limiting hole 1101. The latching assembly 1131 has a first end and a second end. The first end is configured to be pluggably connected to the limiting hole 1101 to limit the connecting slider 1110. The second end is configured to be connected to the reset member 1140 to give the latching assembly 1131 a tendency to move from an unlocked position to a locked position.

[0074] In some embodiments, the unlocking component 1132 and the latching component 1131 form an integral structure. The integrally molded structure has better mechanical strength, a smooth and flat surface, and advantages such as simple operation and high production efficiency during processing. It can also maintain more stable synchronization when the limit switch 1130 switches between the locked and unlocked positions, improving the adjustment efficiency of locking or stopping.

[0075] In some embodiments, the unlocking component 1132 can unlock the locking component 1131 from the limiting hole 1101 by moving up and down. The unlocking component 1132 moves in a second direction, and the locking component 1131 moves in a second direction. The first end of the locking component 1131 has a size that matches the limiting hole 1101 and is pluggably connected to the limiting hole 1101, limiting the connecting slider 1110 by switching between a locked position and an unlocked position. The second end is configured to connect to the reset member 1140 so that the locking component 1131 tends to move from the unlocked position to the locked position.

[0076] In response to the downward movement of the unlocking component 1132, the locking component 1131 moves downward under the action of the unlocking component 1132, so that the first end of the unlocking component 1132 is inserted into the limiting hole 1101, thereby limiting the connection slider 1110 and the guide rail 1120. At the same time, under the elastic force of the reset member 1140, the locking component 1131 increases the pressure towards the limiting hole 1101, preventing the locking component 1131 from disengaging from the limiting hole 1101. In response to the upward movement of the unlocking component 1132, the locking component 1131 moves upward under the action of the unlocking component 1132, so that the first end of the locking component 1131 disengages from the limiting hole 1101, releasing the movement limit of the connecting slider 1110 by the limit switch 1130.

[0077] In some embodiments, the handle 1200 and the connecting slider 1110 can be detached and folded. After the handle 1200 and the connecting slider 1110 are assembled, the handle 1200 can rotate in the plane containing the third direction to achieve folding with the connecting slider 1110.

[0078] In some embodiments, when the handle portion 1200 and the connecting slider 1110 are foldably connected, the handle assembly 1000 has a stored state and an operating state. For example... Figure 4 As shown, when the handle assembly 1000 is in the retracted state, the handheld part 1200 and the connecting slider 1110 extend in the same direction, and the angle between the handheld part 1200 and the connecting slider 1110 is approximately 0°. At this time, the handle assembly 1000 occupies a small space, making it easy for the user to store.

[0079] When the handheld part 1200 is in the working state, such as Figure 5 , Figure 6 As shown, the angle between the extension directions of the handheld part 1200 and the connecting slider 1110 is greater than 0° and less than 180°. Compared to its folded state, the handle assembly 1000 occupies a larger space when in operation, making it inconvenient for users to store. However, when the cleaning device 3000 is in operation, the user can adjust the angle between the handheld part 1200 and the connecting slider 1110 to change the direction of force on the center of gravity of the cleaning device 3000, so that the center of gravity of the handle assembly 1000 and the cleaning device 3000 are on the same straight line. This reduces the bending and torsional forces on the user's arm when using the cleaning device 3000, reduces arm fatigue, and makes the angle between the handheld part 1200 and the connecting slider 1110 more convenient for cleaning the operating surface, thereby improving the user experience.

[0080] In some embodiments, such as Figure 7 , Figure 8 , Figure 9 As shown, the connecting slider 1110 has a rotating portion 1210, and the handheld portion 1200 also includes the rotating portion 1210. The connecting slider 1110 and the rotating portion 1210 are structurally matched, and the connecting slider 1110 and the rotating portion 1210 can be connected by the clamping assembly 1300. In response to the rotating portion 1210 being connected to the connecting slider 1110, the handheld portion 1200 can rotate relative to the connecting slider 1110 about the clamping assembly 1300 to change the angle between the handheld portion 1200 and the first direction.

[0081] Specifically, such as Figure 8 , Figure 9As shown, a first through hole 1101 is provided through the surface of the connecting slider 1110, and a second through hole 1201 is provided through the surface of the rotating part 1210 of the handheld part 1200. In response to contact between the engaging surfaces of the connecting slider 1110 and the rotating part 1210, the first through hole 1101 and the second through hole 1201 communicate. A limiting groove 1102 is provided on the surface of the connecting slider 1110, configured to accommodate at least a portion of the clamping assembly 1300. In this case, the clamping assembly 1300 can be used to limit the connection between the connecting slider 1110 and the rotating part 1210.

[0082] In some embodiments, such as Figure 10 As shown, the clamping assembly 1300 includes a limiting member 1310, a bolt 1320, and a fastener 1330. The limiting member 1310 matches the shape of the limiting groove 1102 of the connecting slider 1110, and the limiting member 1310 has internal threads, configured to be detachably connected to the end of the bolt 1320. The fastener 1330 is fixedly connected to the bolt 1320. During the assembly of the handle 1200 and the connecting slider 1110, the handle 1200 is first fitted to the surface of the connecting slider 1110, and the limiting member 1310 is installed in the limiting groove 1102. Further, the fastener 1330 threadedly connects the bolt 1320 through the first through hole 1101 and the second through hole 1201 from the left side of the connecting slider 1110 to the limiting member 1310. This ensures that the bolt 1320 remains stable relative to the connecting slider 1110, preventing the handle 1200 from wobbling relative to the connecting slider 1110 in the second direction.

[0083] In other embodiments, the limiting member 1310 matches the shape of the limiting groove 1102 of the connecting slider 1110 and is fixedly disposed at the end of the bolt 1320. The fastener 1330 is detachably connected to the bolt 1320. During the assembly of the handle 1200 and the connecting slider 1110, the bolt 1320 can first be inserted through the first through hole 1101 from the left side of the connecting slider 1110, so that the limiting member 1310 is installed in the limiting groove 1102, and the bolt 1320 remains stable relative to the connecting slider 1110. Then, the rotating part 1210 of the handle 1200 and the connecting slider 1110 are aligned and inserted through the bolt 1320, so that the handle 1200 and the connecting slider 1110 are assembled. Furthermore, the fastener 1330 is rotatably mounted on the bolt 1320, so that the handle 1200 is rotatably connected to the connecting slider 1110, while preventing the handle 1200 from wobbling relative to the connecting slider 1110 in the second direction.

[0084] It should be noted that this disclosure does not specifically limit the shape and structure of the limiting groove 1102 and the limiting member 1310. The limiting groove 1102 and the limiting member 1310 can be a rectangular structure, a polygonal structure, or any other shape and structure that can keep the bolt 1320 in a stable position when the fastener 1330 is installed on the bolt 1320.

[0085] In some embodiments, such as Figure 7 , Figure 9 , Figure 11 As shown, the connecting slider 1110 has a first toothed surface 1111 on the side facing the rotating part 1210, and the rotating part 1210 has a second toothed surface 1211 on the side facing the connecting slider 1110. The first toothed surface 1111 and the second toothed surface 1211 mesh and rotate. The first toothed surface 1111 and the second toothed surface 1211 are each provided with multiple gear teeth. These gear teeth are configured to limit the rotation of the handheld part 1200 relative to the connecting slider 1110 during rotation by meshing the gear teeth at different positions. Different rotational limits change the angle between the handheld part 1200 and the connecting slider 1110, allowing for different handheld positions. This facilitates user adjustment of the handheld angle according to needs, making cleaning the operating surface more effortless.

[0086] In some embodiments, the number of teeth on the first toothed surface 1111 and the second toothed surface 1211 can be 3-10. This allows for limiting the handheld portion 1200 at different angles. Figure 12 As shown, the second toothed surface 1211 can be provided with 8 teeth, and the handheld part 1200 has at least 4 limiting positions relative to the support module in the working state. Figure 5 , Figure 6 As shown, when the handheld part 1200 and the connecting slider 1110 are in the limited position, the teeth of the first toothed surface 1111 engage with the recessed portion of the second toothed surface 1211. At this time, without the action of external force, the positions of the handheld part 1200 and the connecting slider 1110 are fixed. When the handheld part 1200 and the connecting slider 1110 are in the limited position, under the action of external force, the position between the handheld part 1200 and the connecting slider 1110 can be changed, so that there is an included angle α between the handheld part 1200 and the connecting slider 1110, where 0°≤α≤180°, to meet the user's usage needs in different scenarios.

[0087] A second aspect of the present disclosure provides a cleaning device 3000, including a cleaning device body 2000 and a handle assembly 1000 provided in the first aspect of the present disclosure.

[0088] In some embodiments, such as Figure 13 As shown, the cleaning device body 2000 includes a main unit assembly 2200 and a dust collection assembly 2100. The main unit assembly 2200 and the dust collection assembly 2100 are detachably connected to the connecting slider 1110 and configured to provide power for the cleaning operation of the dust collection assembly 2100. The main unit assembly 2200 may include structural components such as a battery module, a fan module, and a main control board, used to provide cleaning power for the dust collection assembly 2100. The dust collection assembly 2100 includes a dust collection container 2120 and a dust collection head 2110, which are detachably connected. The dust collection assembly 2100 and the main unit assembly 2200 can be separated or combined. In response to the assembly of the dust collection assembly 2100 with the main unit assembly 2200, the connecting slider 1110 can be installed on the cleaning device body 2000. After the dust collection component 2100 is separated from the main unit component 2200, the overall maximum size of the product becomes smaller, occupying less space and making it very convenient to store.

[0089] Specifically, after the dust collection component 2100 is assembled with the main unit component 2200, the connecting slider 1110 can be installed on the cleaning device body 2000. At this time, the user can hold the handle component 1000 and make the dust collection head 2110 contact the operating surface. Under the power provided by the main unit component 2200, the dust collection head 2110 sucks the dirt on the operating surface into the dust collection cup, thereby cleaning the operating surface.

[0090] In some embodiments, the handheld portion 1200, when in operation, is located directly above the center of gravity of the cleaning device body 2000. Specifically, as... Figure 14 , Figure 15 As shown, when the operating surface is the ground, the dust collection head 2110 of the dust collection assembly 2100 is configured to suck the dust on the operating surface into the dust collection cup under the power provided by the main unit 2200. At this time, since the user needs to hold the cleaning device 3000, the cleaning device 3000 is tilted relative to the operating surface, and the handle 1200 is located directly above the center of gravity of the cleaning device body 2000. In this situation, the position of the user holding the handle 1200 is at the same torque as the center position of the cleaning device 3000, making it easier for the user to clean the operating surface.

[0091] In some embodiments, the handheld portion 1200, when in operation, is located directly below the center of gravity of the cleaning device body 2000. Specifically, as... Figure 16 As shown, when the operating surface is a ceiling surface, the dust collection head 2110 of the dust collection assembly 2100 is configured to suck the dust on the operating surface into the dust collection cup under the power provided by the main unit 2200. At this time, since the user needs to hold the cleaning device 3000, the cleaning device 3000 is tilted relative to the operating surface, and the handle 1200 is located directly below the center of gravity of the cleaning device body 2000. In this case, the user holds the handle assembly 1000 and the center of gravity of the cleaning device 3000 in a straight line, reducing the bending and torsional forces on the user's arm when using the cleaning device 3000, reducing arm fatigue, and thus improving the user experience.

[0092] In some embodiments, when the handle 1200 is in operation, the center of gravity of the cleaning device body 2000 is located in the extending direction of the handle 1200. Specifically, as Figure 17 As shown, when the operating surface is a wall, the dust collection head 2110 of the dust collection assembly 2100 is configured to suck the dust on the operating surface into the dust collection cup under the power provided by the main unit 2200. At this time, the center of gravity of the handle assembly 1000 and the cleaning device 3000 are on the same straight line when the user holds the device, reducing the bending and torsional forces on the user's arm when using the cleaning device 3000, reducing arm fatigue when using the cleaning device 3000, and thus improving the user experience.

[0093] In some embodiments, the host component 2200 includes a display module 2300 disposed on a sidewall of the host component 2200. For example... Figure 13 As shown, the display module 2300 is placed on the side wall of the main unit, making it convenient for users to observe information such as the status of the main unit. The display module 2300 can be an LED display screen, an LCD display screen, or a flexible screen. It is configured to display information such as the remaining power of the cleaning device 3000 and the remaining capacity of the dust collection container 2120.

[0094] The specific structure, working principle, and beneficial effects of the handle assembly and cleaning device provided in this disclosure can be found in any of the above embodiments of the handle assembly and cleaning device, and will not be repeated here.
