[0048] ​In order to make the purposes, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present disclosure.

[0049] The terms used in the embodiments of the present disclosure are only for the purpose of describing particular embodiments and are not intended to limit the present disclosure. The singular forms "a", "an" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "Plural" generally includes at least two, and other quantifiers are similar.

[0050] It should be understood that although the terms first, second, third, etc. can be used in the embodiments of the present disclosure to describe, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, without departing from the scope of the embodiments of the present disclosure, the first can also be referred to as the second, and similarly, the second can also be referred to as the first. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0051] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship. The singular forms "a", "said" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0052] In the description of the present disclosure, it should be explained that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0053] It is also important to note that the terms "comprises" and / or "comprising," or other variations such as "includes," "including" or "contains," "containing," etc., shall not be construed as the use of an exclusive or exhaustive listing of the components described. That is, the use of these terms to describe the composition of a product or process does not require that the product or process include only the components of the list, but rather, the listed components must be included in the product or process, and other components can also be included in the product or process.

[0054] Currently, cleaning devices such as vacuum cleaners, mite removers, etc. in the market have handles that are not foldable and are located at the back, which causes the center of gravity of the device to be unstable or the user to hold the device with great effort. Specifically, in the related art, the battery, fan, main control board, etc. of the vacuum cleaner, mite remover, etc. are arranged below the handle. Since the front end of the device also has a dust cup, filter screen module, dust collecting head, or brush head, etc., the center of gravity and the action position of the handle are not on the same vertical line, and the center of gravity is in front of or behind the handle. According to the principle of a lever, the user holds the product with great force, and in addition to bearing the weight of the product, the user also needs to bear a bending torque, which results in a poor experience and the arm is tired after a long time of operation. In addition, the surface of the cleaning device needs to be separately provided with a containing space to open the button, which increases the utilization rate of the surface of the main body of the cleaning device and is not conducive to the aesthetic design. During use, the user needs to press the opening button separately to separate the dust collecting head from the main body of the cleaning device.

[0055] Therefore, the cleaning device provided by the embodiments of the present disclosure includes a cleaning device main body provided with a containing space, a dust collecting assembly rotationally connected with the cleaning device main body and having a closed position and an open position, the dust collecting assembly being configured to close the containing space and suck dirt on an operation surface into the containing space, and a handle assembly including a guide rail arranged on the cleaning device main body and a connecting sliding block slidingly arranged on the guide rail and having a locking state and an unlocking state. When the connecting sliding block is in the unlocking state, the connecting sliding block has a working position and a dumping position, and in response to the handle assembly being switched from the working position to the dumping position, the dust collecting assembly is switched from the closed position to the open position.

[0056] The cleaning device provided by the present disclosure has a movable handle assembly, and through the switching of the connecting sliding block between the working position and the dumping position, the containing space can be opened by the handle assembly to realize the dumping of dirt. The cleaning device provided by the present disclosure not only makes the dumping of dirt convenient, but also saves the independent arrangement of the containing space opening button, which is convenient for the user to use and is conducive to saving the design space on the main body of the cleaning device.

[0057] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0058] The cleaning device 4000 is provided in the embodiments of the present disclosure. In order to more clearly describe the behavior of the cleaning device 4000, the following direction definitions are made with the working direction of the cleaning device 4000 as the reference: a front-rear axis X, a lateral axis Y, and a central vertical axis Z. The direction opposite to the arrow direction along the front-rear axis X is the forward movement direction of the cleaning device 4000 in normal working, which is marked as "forward", and the arrow direction along the front-rear axis X is the backward movement direction of the cleaning device 4000 in normal working, which is marked as "backward", wherein the direction of the front-rear axis X is the first direction. The lateral axis Y is substantially along the direction of the width of the cleaning device 4000, the arrow direction along the lateral axis Y is marked as "rightward", and the arrow direction opposite to the lateral axis Y is marked as "leftward", wherein the direction of the lateral axis Y is the second direction. The vertical axis Z is along the vertical direction of the self-moving device, the arrow direction along the vertical axis Z is marked as "upward", and the arrow direction opposite to the vertical axis Z is marked as "downward", wherein the direction of the vertical axis Z is the third direction.

[0059] In some embodiments, the cleaning device 4000 includes the cleaning device body 2000, a dust collection assembly, and a handle assembly 1000. The cleaning device body 2000 is provided with a receiving space 2001 for accommodating dust sucked by the dust collection assembly, and the handle assembly 1000 is arranged on the cleaning device body 2000, and at least part of the handle assembly 1000 can move relative to the cleaning device body 2000. As shown in Figure 1 Figure 2 The dust collection assembly 3000 is rotatably connected to the cleaning device body and has a closed position and an open position. The dust collection assembly 3000 is configured to close the receiving space 2001 and suck dust on the operation surface into the receiving space 2001. When at least part of the handle assembly 1000 is switched from the working position to the dumping position, the dust collection assembly 3000 is switched from the closed position to the open position, so that the dust in the receiving space 2001 can be dumped through the handle assembly.

[0060] In some embodiments, the dust collection assembly 3000 includes an end cover 3100 and a dust collection head 3200. The end cover 3100 is movably arranged on the cleaning device body and is configured to close the receiving space 2001. The dust collection head 3200 is arranged on the end cover 3100 and is configured to suck dust on the operation surface into the receiving space 2001. Figure 2 Figure 3 ​​As shown, the end cover 3100 is provided with a connecting portion 3110 and a clamping portion 3120 at two ends in the radial direction, respectively, the connecting portion 3110 is configured to be rotatably connected with the cleaning device body 2000, and the clamping portion 3120 is configured to be clamped with the cleaning device body 2000. An installation hole 3130 is provided in the middle of the end cover 3100, and the dust collecting head 3200 is connected with the end cover 3100 through the installation hole 3130 and is configured to suck the dust on the operation surface into the containing space 2001.

[0061] In some embodiments, a clamping piece 2100 is provided between the cleaning device body 2000 and the handle assembly and is configured to be clamped with the clamping portion 3120 to close the containing space 2001, as shown in Figure 4 As shown, the clamping piece 2100 includes a clamping hook portion 2110, a pushing portion 2120, and an installation column 2130. The clamping hook portion 2110 is provided at the end of the clamping piece 2100 and is configured to be clamped with the clamping portion 3120 of the end cover 3100 to close the containing space 2001, and the pushing portion 2120 is provided on the upper surface of the clamping piece 2100 and at least partially penetrates the guide rail 1120 and is configured to move the entire clamping piece 2100 downward under the action of an external force. The installation column 2130 is provided on the bottom surface of the clamping piece 2100 and is configured to install a first reset piece 2140, and the installation column 2130 can be provided with two or more. The installation column 2130 can be a “cross column”, or any other structure that can install the first reset piece 2140, and the present disclosure does not limit this.

[0062] In some embodiments, the clamping piece 2100 has a clamping position and a release position and is configured to clamp or release the dust collecting assembly 3000 and the containing space 2001. In response to the clamping piece 2100 being in the clamping position, the clamping hook portion 2110 is clamped with the clamping portion 3120 of the end cover 3100, at which time the dust collecting assembly 3000 closes the containing space 2001, the dust collecting assembly 3000 is in the closed position, and the cleaning device can clean the operation surface; in response to the clamping piece 2100 being in the release position, the clamping hook portion 2110 is disengaged from the clamping portion 3120 of the end cover 3100, at which time the dust collecting assembly 3000 is disengaged from the cleaning device body under the action of gravity, the dust collecting assembly 3000 is in the open position, and the dumping of the dust in the containing space 2001 can be achieved.

[0063] In some embodiments, as shown in Figure 5As shown, the handle assembly 1000 comprises a guide rail 1120, a moving slider 1110 and a hand-held part 1200. The guide rail 1120 extends along the first direction and is connected to the cleaning device main body 2000. The hand-held part 1200 is movably connected to the moving slider 1110, specifically, the hand-held part 1200 is detachably connected to the moving slider 1110, and the hand-held part 1200 can be assembled with or separated from the moving slider 1110 as needed. The moving slider 1110 has a size matching that of the guide rail 1120, so that the moving slider 1110 can slide along the guide rail 1120.

[0064] In some embodiments, the moving slider 1110 and the guide rail 1120 have a locked state and an unlocked state. When the moving slider 1110 and the guide rail 1120 are in the unlocked state, the moving slider 1110 can drive the hand-held part 1200 to move freely along the guide rail 1120 as a whole. When the moving slider 1110 and the guide rail 1120 are in the locked state, the position of the moving slider 1110 is limited relative to the guide rail 1120, so that the moving slider 1110 cannot drive the hand-held part 1200 to move freely along the guide rail 1120 as a whole. At this time, the user can hold the hand-held part 1200 to clean the operation surface with the cleaning device 4000.

[0065] In some embodiments, the moving slider 1110 comprises a pressure-stopping part 1111 arranged at one end of the moving slider 1110 adjacent to the locking piece 2100. The pressure-stopping part 1111 has a similar structure to the pushing part 2120 and is configured to switch the locking piece 2100 from the locking position to the releasing position.

[0066] In some embodiments, as shown, Figure 6 As shown, the guide rail 1120 further comprises a first limiting hole 1101 arranged along the first direction on the guide rail 1120. There are at least two first limiting holes 1101 arranged on the guide rail 1120, and the moving slider 1110 can drive the hand-held part 1200 to switch between the at least two first limiting holes 1101 to change the connection position of the hand-held part 1200 relative to the guide rail 1120, i.e., the at least two first limiting holes 1101 are configured to change the relative position between the hand-held part 1200 and the guide rail 1120.

[0067] In some embodiments, as shown, Figure 6As shown, the guide rail 1120 can be provided with a second limiting hole adjacent to one end of the dust collecting assembly 3000, and the pushing part 2120 of the locking piece 2100 can be exposed from the second limiting hole. When the connecting slider 1110 is in the unlocked state, the connecting slider 1110 has a working position and a dumping position. Specifically, in response to the connecting slider 1110 being in the working position, the connecting slider 1110 is slidingly arranged between at least two first limiting holes; in response to the connecting slider 1110 being in the dumping position, the pressure stopping part 1111 covers the second limiting hole, so that the locking piece 2100 is switched from the locking position to the releasing position.

[0068] When the handle assembly is switched from the working position to the dumping position, the dust collecting assembly 3000 can be switched from the closed position to the open position, so that the dirt dumping of the cleaning device is realized through the handle assembly, the dirt dumping process is more convenient, and the independent setting of the opening button of the accommodation space 2001 is saved, which is convenient for users to use and more conducive to saving the design space on the main body of the cleaning equipment.

[0069] In some embodiments, the first limiting hole 1101 can be provided in plurality, and the plurality of first limiting holes 1101 are equidistantly arranged along the first direction on the guide rail 1120. The distance between adjacent two first limiting holes 1101 can be 5-20 mm. Figure 5 As shown, the distance between the first limiting holes 1101 is about 6 mm. Since the distance between the first limiting holes 1101 is small, more first limiting holes 1101 can be arranged on the limited length of the guide rail 1120. When the contact angle of the cleaning device 4000 with the operating surface is different, the position of the center of gravity of the cleaning device 4000 will also change. At this time, the position relationship between the handheld part 1200 and the center of gravity can be adjusted by adjusting the position of the handheld part 1200 on the guide rail 1120, so that the user holds the cleaning device 4000 more labor-saving.

[0070] In some embodiments, the first limiting holes 1101 can be concentrated on a part of the guide rail 1120. Specifically, the first 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 part of the moving area on the guide rail 1120, in order to save the opening time and improve the processing efficiency of the production link, the rear half of the guide rail 1120 is a non-hole area, and the length of the non-hole area is about the length of the handheld part 1200 in the first direction.

[0071] In some embodiments, as shown in Figure 7As shown, the hand-held part 1200 further comprises a limit switch 1130 movably arranged on the connecting slider 1110, having a locked state and an unlocked state, and the limit switch 1130 is configured to be movably connected with the first limit hole 1101. Specifically, when the limit switch 1130 is in the locked state, at least part of the limit switch 1130 is located in the first limit hole 1101, so that the hand-held part 1200 is locked with the guide rail 1120. When the limit switch 1130 is in the unlocked state, the limit switch 1130 is separated from the first limit hole 1101, and the hand-held part 1200 can move freely relative to the guide rail 1120. Wherein, when the limit switch 1130 is in the locked state, the user can hold the hand-held part 1200 to clean the operation surface by using the cleaning device 4000.

[0072] In some embodiments, as Figure 7 As shown, the limit switch 1130 comprises a locking component 1131 and an unlocking component 1132. The locking component 1131 is arranged inside the connecting slider 1110, one end of the locking component 1131 has a matching shape structure with the first limit hole 1101, and is configured to be inserted into the first limit hole 1101 to lock the connecting slider 1110 with the guide rail 1120. The unlocking component 1132 is arranged outside the connecting slider 1110, and is configured to unlock the locking component 1131 from the first limit hole 1101. Wherein, the connecting slider 1110 is provided with a moving space of the unlocking component 1132 on the cleaning device body, and the locking relationship between the locking component 1131 and the first limit hole 1101 can be changed by moving the unlocking component 1132.

[0073] Specifically, when the limit switch 1130 is in the locked state, at least part of the locking component 1131 penetrates through the first limit hole 1101 to achieve locking, thereby preventing the connecting slider 1110 from moving on the guide rail 1120. When the limit switch 1130 is in the unlocked state, the unlocking component 1132 drives the locking component 1131 to move away from the guide rail 1120, so that the locking component 1131 is separated from the first limit hole 1101, and at this time, the connecting slider 1110 can move freely relative to the guide rail 1120.

[0074] In some embodiments, the limit switch 1130 further comprises a second reset member 1140, which can be connected with the lock catch assembly 1131 and configured to make the lock catch assembly 1131 catch with the first limit hole 1101. Wherein the lock catch assembly 1131 has a first end and a second end, the first end is configured to be pluggably connected with the first limit hole 1101 to limit the connecting slider 1110, and the second end is configured to be connected with the second reset member 1140 to make the lock catch assembly 1131 have a tendency to move from the unlocked state to the locked state.

[0075] In some embodiments, the unlocking assembly 1132 and the lock catch assembly 1131 form an integral structure. The integral structure has better mechanical strength, smooth and flat surface, and has the advantages of simple operation, high production efficiency and the like in the processing process. It can make the limit switch 1130 keep more stable synchronization when switching between the locked state and the unlocked state, and improve the adjustment efficiency of locking or locking.

[0076] In some embodiments, the unlocking assembly 1132 can unlock the lock catch assembly 1131 from the first limit hole 1101 through up and down movement. The unlocking assembly 1132 moves in the second direction, and the lock catch assembly 1131 moves in the second direction. The first end of the lock catch assembly 1131 has a size matched with the first limit hole 1101, and is pluggably connected with the first limit hole 1101 to limit the connecting slider 1110 through switching between the locked state and the unlocked state. The second end is configured to be connected with the second reset member 1140 to make the lock catch assembly 1131 have a tendency to move from the unlocked state to the locked state.

[0077] In response to the downward movement of the unlocking assembly 1132, the lock catch assembly 1131 moves downward under the driving of the unlocking assembly 1132 to make the first end of the unlocking assembly 1132 inserted into the first limit hole 1101, and realize the limiting of the connecting slider 1110 and the guide rail 1120. At the same time, the lock catch assembly 1131 enhances the pressure in the direction of the first limit hole 1101 under the elastic force of the second reset member 1140, to avoid the lock catch assembly 1131 from being pulled out of the first limit hole 1101. In response to the upward movement of the unlocking assembly 1132, the lock catch assembly 1131 moves upward under the driving of the unlocking assembly 1132 to make the first end of the lock catch assembly 1131 disengaged from the first limit hole 1101, and release the movement limitation of the connecting slider 1110 by the limit switch 1130.

[0078] In some embodiments, the handheld part 1200 and the connecting slider 1110 are detachable and foldable.
