Description

Technical Field

[0001] The present application relates to the field of cleaning, and in particular to a cleaning device. Background Art

[0002] With the improvement of living standards, people pay more and more attention to environmental hygiene, and cleaning equipment has become an important tool for people to ensure environmental hygiene. Among them, a roller brush is usually used in the cleaning equipment to clean the dirty surface.

[0003] In existing cleaning equipment, the roller brush assembly used for cleaning is generally detachably mounted on the floor brush base. Specifically, the roller brush is mainly detachably connected to the floor brush base by means of magnetism or snap-on. However, the roller brush with a magnetic structure is relatively expensive and easily loses its adsorption state when subjected to a large impact force. The roller brush with a snap-on connection will be tightly locked on the floor brush base, which increases the difficulty of disassembly. It is time-consuming and laborious for the user to disassemble, which greatly affects the user experience. Therefore, how to ensure that the roller brush is firmly installed while improving the convenience of disassembly has become a technical problem that urgently needs to be solved.

[0020] Optionally, the top contact portion is provided with a top contact surface in contact with the clamping plate;

[0021] When the top contact portion pushes into the inner space of the card plate and completely pushes the abutment portion out of the inner space of the card plate, the gap between the top contact surface of the top contact portion and the card plate is insufficient for the abutment portion to push in.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0046] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] The present application provides a cleaning device, and the structure and working principle of the cleaning device of the present application are described below using specific embodiments. It should be noted that the embodiments described below are only embodiments of a part of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. The cleaning device involved in the present application is described in detail below.

[0048] The first embodiment of the present application provides a cleaning device, and the cleaning device in the present application can be a handheld cleaning device, a fully automatic cleaning device such as an automatic floor scrubber, or other cleaning devices equipped with a floor brush assembly. In a specific working scenario, the floor brush assembly installed on the cleaning device is mainly used to clean pollutants attached to a dirty surface, and the roller brush in the floor brush assembly is used to directly contact the dirty surface for cleaning.

[0049] Existing cleaning equipment mainly includes a floor brush base and a roller brush assembly. The roller brush assembly is installed on the floor brush base, and under the action of the floor brush base, the roller brush in the roller brush assembly contacts the dirty surface, thereby achieving cleaning. In order to facilitate the replacement of the roller brush, the roller brush assembly is generally detachably installed on the floor brush base.

[0050] Specifically, the roller brush assembly is detachably connected to the floor brush base mainly by means of magnetic or snap connection. Specifically, the magnetic connection method is to set a magnet on the floor brush base or the roller brush assembly so that the roller brush assembly is fixed on the floor brush base under the action of magnetic force. The snap connection method is to set a snap structure and a clamping structure that cooperate with each other on the floor brush base and the roller brush assembly so that the roller brush assembly is tightly clamped on the floor brush base.

[0051] However, in the magnetic connection method, the magnet is expensive, and the magnetic structure is easy to lose the adsorption state when subjected to a large impact force, resulting in an unstable connection between the roller brush assembly and the floor brush base. In the buckle connection method, the buckle will lock the roller brush assembly tightly on the floor brush base. When the user disassembles it, he needs to specifically unlock the lock state at each buckle position, and then hold the entire roller brush assembly to separate it from the floor brush base, which is time-consuming and labor-intensive, affecting the user experience.

[0052] In order to solve the problem that the above-mentioned existing cleaning equipment cannot simultaneously ensure the stability of the roller brush installation and the convenience of disassembly, the present application provides a corresponding cleaning equipment.

[0053] In this embodiment, the cleaning device includes a floor brush base and a roller brush assembly. A protruding handle is provided at the first axial end of the roller brush body of the roller brush assembly and in a direction perpendicular to the axial direction of the roller brush body. A mutually fitting structure, as well as a mutually cooperating locking buckle and a clamping structure are provided on the first side of the protruding portion of the handle and the side surface of the floor brush base, and the locking buckle and the clamping structure are respectively located on the first side of the protruding portion of the handle and the side surface of the floor brush base.

[0054] When the roller brush assembly is installed in the floor brush base, and the locking buckle is located on the disassembly path of the snap-fit ​​structure, or the snap-fit ​​structure is located on the disassembly path of the locking buckle, the first side surface of the extension of the handle and the side surface of the floor brush base fit each other, and the locking buckle and the snap-fit ​​structure are close to each other and snap-fit ​​as the roller brush assembly is installed. In addition, a rotating part is also provided on the extension of the handle. When the rotating part rotates in a direction away from the side surface, the locking buckle and the snap-fit ​​structure are separated from each other, and the locking buckle withdraws from the disassembly path of the snap-fit ​​structure, or the snap-fit ​​structure withdraws from the disassembly path of the locking buckle. In this type of cleaning device, the mutual engagement of the locking buckle and the snap-fit ​​structure enables the roller brush assembly to be reliably installed on the floor brush base without falling off. When disassembling, the user only needs to pull out the roller brush assembly after rotating the rotating part, without consuming a lot of time and effort, thereby improving the user experience.

[0055] In order to understand the structure of the above cleaning equipment, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 A first structural schematic diagram of a cleaning device provided in the first embodiment, Figure 2 A second structural schematic diagram of the cleaning device provided in the first embodiment, Figure 3 The third structural schematic diagram of the cleaning device provided in the first embodiment. The cleaning device of this embodiment comprises: a floor brush base 10 and a roller brush assembly 20.

[0056] Specifically, the roller brush assembly 20 includes a roller brush body 21, a handle 22 and a rotating member 23. Specifically, a protruding handle 22 is provided at the first axial end portion 211 of the roller brush body 21 of the roller brush assembly 20 and in a direction perpendicular to the axial direction of the roller brush body 21; the handle 22 includes a shaft support portion 221 and a protruding portion 222; the shaft support portion 221 is a portion combined with the first end portion 211 of the roller brush body 21, and is provided with a structure for providing rotation support for the roller brush body 21; the protruding portion 222 of the handle 22 faces the first side surface 2220 of the floor brush base 10, and is provided with a structure capable of being mutually fitted with the side surface 100 of the floor brush base 10 opposite thereto.

[0057] In this embodiment, in response to different cleaning methods and requirements, the roller brush body 21 can be set to different shapes, such as a cylindrical barrel as a whole, a cylindrical shape with two ends converged, or an elliptical structure. In addition, the outer side of the roller brush body is the side that directly contacts the dirty surface, and different materials suitable for dirty cleaning can be used, which is not limited here.

[0058] In this embodiment, the roller brush body 21 is rotatably mounted on the floor brush base 10. Specifically, the first axial end 211 of the roller brush body 21 is provided with an extended handle 22, and the handle 22 is used to install the roller brush body on the floor brush base. The two ends of the handle 22 are respectively a shaft support portion 221 and an extended portion 222. The portion of the shaft support portion 221 that is combined with the first end 211 of the roller brush body 21 can be provided with a bearing for support, and a bearing shell, a sleeve and other structures can be further added to the bearing structure, or a bearing can be directly sleeved without a bearing, which is not limited here.

[0059] The other end corresponding to the first end 211 of the roller brush body 21 in the axial direction, that is, the second end 212, can be directly rotatably connected to the floor brush base 10, that is, a structure supporting the second end 212 of the roller brush body 21 is provided on the floor brush base. When the first end 211 of the roller brush body 21 is installed on the floor brush base 10 through the handle 22, the first end 211 and the second end 212 of the roller brush body 21 are supported on the handle 22 and the floor brush base 10 respectively, and the roller brush body is equivalent to being rotatably clamped between the floor brush base 10 and the handle 22. This structural form makes the installation direction of the roller brush assembly consistent with the axial direction of the roller brush, which is convenient for installation and disassembly.

[0060] In addition, another handle may be provided at the second end portion 212 of the roller brush body 21 , similar to the handle 22 , to support the second end portion 212 of the roller brush body 21 . The specific structure thereof is similar to the handle 22 , and will not be described in detail herein.

[0061] In this embodiment, the extension portion 222 of the handle 22 is used to be fixedly connected to the floor brush base 10. Specifically, the first side surface 2220 of the extension portion 222 of the handle corresponds to the side surface 100 of the floor brush base 10, that is, when installed, the first side surface 2220 of the extension portion 222 is directed toward the side surface 100 of the floor brush base 10, and the first side surface 2220 of the extension portion 222 and the side surface 100 of the floor brush base 10 can be respectively provided with mutually fitting structures, so that the first side surface 2220 and the side surface 100 are closely fitted.

[0062] In a feasible implementation, the mutually fitting structure can be specifically that a groove is provided on the side surface 100 of the floor brush base 10, and a boss corresponding to the groove is provided on the first side 2220 of the extension 222 of the handle 22; when the roller brush assembly 20 is installed in the floor brush base 10, the boss of the first side 2220 is received in the groove of the side surface 100. Alternatively, a boss is provided on the side surface 100 of the floor brush base 10, and a groove corresponding to the boss is provided on the first side 2220 of the extension 222 of the handle 22; when the roller brush assembly 20 is installed in the floor brush base 10, the groove of the first side 2220 wraps the boss of the floor brush base 10.

[0063] In the cleaning device of this embodiment, the locking of the handle 22 and the floor brush base 10 is achieved by a locking buckle and a locking structure. Specifically, a locking buckle 40 or a locking structure 41 is provided at a preset position of the first side 2220 of the extension 222 of the handle 22; accordingly, a locking structure 41 corresponding to the locking buckle 40 or a locking buckle 40 corresponding to the locking structure 41 is provided on the side surface 100 of the floor brush base 10; when the roller brush assembly 20 is installed in the floor brush base 10, the locking buckle 40 is located on the disassembly path of the locking structure 41, or the locking structure 41 is located on the disassembly path of the locking buckle 40.

[0064] In other words, the locking buckle and the snap-fit ​​structure are mutually matched structures and can be located on the handle 22 and the floor brush base 10, respectively. Figure 2 and Figure 3 As shown, the locking buckle 40 can be arranged on the side surface 100 of the floor brush base 10, and can be arranged on Figure 2 and Figure 3 Correspondingly, at the position shown, a snap-fit ​​structure 41 corresponding to the locking buckle 40 is provided on the first side surface 2220 of the extending portion 222 of the handle 22 , and the locking buckle 40 is located on the disassembly and assembly path of the snap-fit ​​structure 41 .

[0065] Alternatively, you can Figure 2The positions of the locking buckle 40 and the snap-on structure 41 shown in the figure are interchanged, that is, the snap-on structure 41 is arranged on the side surface 100 of the floor brush base 10, and the locking buckle 40 is arranged on the first side surface 2220 of the protruding portion 222 of the handle 22, and the snap-on structure 41 is located on the disassembly and assembly path of the locking buckle 40.

[0066] It should be clear that the positions of the locking buckle 40 and the clamping structure 41 correspond to each other. When the locking buckle 40 is located on the disassembly path of the clamping structure 41, the locking buckle 40 is a component that actively moves relative to the clamping structure 41. At this time, the locking buckle 40 can approach the clamping structure 41 along the disassembly path and be clamped with the clamping structure 41. It is also possible that after the two are released from clamping, the locking buckle 40 moves away from the clamping structure 41 along the disassembly path. Similarly, when the clamping structure 41 is located on the disassembly path of the locking buckle 40, the clamping structure 41 is a component that actively moves relative to the locking buckle 40. At this time, the clamping structure 41 can approach the locking buckle 40 along the disassembly path and be clamped with the locking buckle 40. It is also possible that after the two are released from clamping, the clamping structure 41 moves away from the locking buckle 40 along the disassembly path.

[0067] Furthermore, a rotating member 23 is also provided on the extending portion 222 of the handle 22. When the rotating member 23 rotates in a direction away from the side surface 100, the locking buckle 40 is released from the locking structure 41, so that the locking buckle 40 withdraws from the disassembly path of the locking structure 41, or the locking structure 41 withdraws from the disassembly path of the locking buckle 40.

[0068] In this embodiment, a rotating member 23 for disassembling the roller brush assembly 20 is provided on the extension portion 222 of the handle 22, and the rotating member 23 can exert a disassembly force on the locking buckle 40 or the clamping structure 41 when rotating in a direction away from the side surface 100, thereby releasing the mutual clamping between the locking buckle 40 and the clamping structure 41. The rotating member 23 can be set as a rotatable pull ring, pull rod, etc., which is not limited here.

[0069] When the roller brush assembly 20 is installed in the floor brush base 10, the locking buckle 40 is located on the disassembly path of the clamping structure 41, and the locking buckle 40 can automatically engage with the clamping structure 41, and the rotating member 23 is in contact with the side surface 100. When the rotating member 23 rotates in a direction away from the side surface 100, the rotating member 23 applies a force to the locking buckle 40 or the clamping structure 41 during the rotation process, thereby releasing the mutual engagement between the locking buckle 40 and the clamping structure 41, so that the locking buckle 40 withdraws from the disassembly path of the clamping structure 41, and the roller brush assembly 20 can be withdrawn from the floor brush base 10.

[0070] There are many specific structures of the rotating member 23. For example, the rotating member 23 can be configured to contact the locking buckle 40 or the clamping structure 41 during the rotation process, so as to release the mutual clamping of the locking buckle 40 and the clamping structure 41 through the contacting action. The rotating member 23 can also be configured to release the mutual clamping of the locking buckle 40 and the clamping structure 41 through a pulling action, or to release the mutual clamping of the locking buckle 40 and the clamping structure 41 through other actions, which is not specifically limited here.

[0071] A rotating member 23 that releases the mutual engagement of the locking buckle 40 and the engaging structure 41 by a top-touching action can be as follows: Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the structure when the locking buckle and the snap-fit ​​structure provided in the first embodiment are locked with each other. Figure 5 This is a schematic structural diagram of the first embodiment when the rotating member is pulled up and the mutual locking between the locking buckle and the snap-fit ​​structure is released.

[0072] Among them, the rotating member 23 has a handle 231 and a top contact portion 233 configured to move with the handle 23; the handle 231 can be pulled to rotate in a direction away from the side surface 100, and drive the top contact portion 233 to touch the locking buckle 40, thereby releasing the mutual engagement between the locking buckle 40 and the clamping structure 41, so that the locking buckle 40 can be withdrawn from the disassembly path of the clamping structure 41, or the clamping structure 41 can be withdrawn from the disassembly path of the locking buckle 40.

[0073] In this embodiment, the rotating member 23 is disposed on the handle extension 222 and is used to disassemble the roller brush assembly 20. When the roller brush assembly 20 needs to be disassembled, the handle 231 is directly pulled, and the handle 231 rotates in a direction away from the side surface 100 of the floor brush base 10. During the rotation of the handle 231, the top contact portion 233 is driven to contact the locking buckle 40, and a force is applied to the locking buckle 40 until the locking buckle 40 and the clamping structure 41 are released from the mutual clamping.

[0074] The process of removing the roller brush assembly 20 from the floor brush base 10 is shown in Figure 6 and Figure 7 ,in, Figure 6 A schematic diagram of the overall structure of the cleaning device provided by the first embodiment when the rotating member is pulled up during the process of removing the roller brush assembly from the floor brush base; Figure 7 A schematic diagram of the structure of the roller brush assembly provided in the first embodiment after being separated from the floor brush base.

[0075] Specifically, when disassembling the roller brush assembly, first follow the steps below: Figure 6As shown, pull up the rotating member until the locking buckle 40 and the locking structure 41 are released from each other (i.e., the locking is released). At this time, although the roller brush assembly 20 is still in contact with the floor brush base 10, the two can be separated. Figure 6 As shown, the roller brush assembly 20 is pulled out, so that the roller brush assembly 20 and the floor brush base 10 are completely separated, thereby completing the disassembly of the roller brush assembly 20.

[0076] Furthermore, the rotating member 23 can also be configured as follows: when the rotating member 23 rotates in a direction away from the side surface 100, after the locking buckle 40 and the snap-fit ​​structure 41 are released from the snap-fitting connection, the locking buckle 40 or the snap-fitting structure 41 moves along the extension direction of the handle 22, so that the locking buckle 40 withdraws from the disassembly path of the snap-fitting structure 41, or the snap-fitting structure 41 withdraws from the disassembly path of the locking buckle 40.

[0077] Taking the withdrawal of the locking buckle 40 from the disassembly path of the clamping structure 41 as an example, the disassembly path of the clamping structure 41 is consistent with the extension direction of the handle 22. The force exerted by the rotating member 23 on the locking buckle 40 during the rotation process causes the locking buckle 40 to move along the extension direction of the handle 22. In this embodiment, the relative positions of the locking buckle 40 and the clamping structure 41 are also arranged relatively along the extension direction of the handle 22, which can make the position layout of the locking buckle 40 and the clamping structure 41 more reasonable, which is conducive to utilizing the length space of the side of the roller brush and avoiding occupying the width space of the base of the floor brush.

[0078] The above is the cleaning device provided by this embodiment. The cleaning device realizes the stable installation of the roller brush assembly on the floor brush base through the mutual cooperation of the locking buckle and the clamping structure, and a corresponding rotating part is provided at the same time. When the user pulls the rotating part, the locking buckle withdraws from the disassembly and assembly path of the clamping structure, or the clamping structure withdraws from the disassembly and assembly path of the locking buckle. In short, when the user pulls the rotating part, the locking state of the locking buckle and the clamping structure is automatically unlocked. After unlocking, the user can directly pull the rotating part to pull out the roller brush assembly, thereby simplifying the disassembly steps of the cleaning assembly, thereby achieving the effect of saving time and effort, and improving the user's experience.

[0079] It should be noted that the structure of the above-mentioned cleaning device is only the basic structure of this embodiment. In the specific implementation process, more specific components can be set on the basis of the cleaning device introduced above, or other feasible structures can be added to obtain more functions or performances to meet the needs of different application scenarios. The following is a further detailed introduction to the specific details based on the structure of the above-mentioned cleaning device to fully understand the above-mentioned cleaning device.

[0080] In this embodiment, in the above-mentioned cleaning device, the locking buckle 40 can be located on the floor brush base 10, and correspondingly, the snap-fit ​​structure 41 is located on the first side 2220 of the extension 222 of the handle 22. The following feasible implementations are all supplementary explanations based on this structure. When the locking buckle 40 is located on the first side 2220 of the extension 222 of the handle 22, and the snap-fit ​​structure 41 is located on the floor brush base 10, the same concept of the following specific structure can also be used for corresponding settings, and no unnecessary details are given here.

[0081] In this embodiment, the locking buckle 40 and the clamping structure 41 corresponding to the locking buckle 40 can be configured as a variety of different specific structures. Correspondingly, the specific structure of the rotating member 23 will also be adaptively changed in accordance with the different specific structures.

[0082] Specifically, the specific structure in which the locking buckle 40 and the snap-fit ​​structure 41 cooperate with each other can press the roller brush assembly 20 against the floor brush base 10 in the form of an abutting card plate, thereby achieving the mutual snap connection between the locking buckle 40 and the snap-fit ​​structure 41.

[0083] Furthermore, if Figure 4 and Figure 5 As shown, the locking buckle 40 includes a contact portion 401; the clamping structure 41 includes a clamping plate 411; when the roller brush assembly 20 is installed into the floor brush base 10, when the protruding portion 222 of the handle 22 is in contact with the side surface 100 of the floor brush base 10, the contact portion 401 and the clamping plate 411 contact each other during the bonding process and finally intertwine with each other, and the contact portion 401 is located on the disassembly and assembly path of the clamping plate 411, so that the clamping structure 41 and the locking buckle 40 are clamped with each other; when unlocking is required, the top contact portion 233 contacts the locking buckle 40, specifically, the top contact portion 233 is configured to be able to move with the rotation of the handle 231 when the handle 231 rotates, and move to support the abutment portion 401, thereby pushing the abutment portion 401 until the mutual clamping of the clamping structure 41 and the locking buckle 40 is released, so that the locking buckle 40 is withdrawn from the disassembly and assembly path of the clamping structure 41.

[0084] In another embodiment, the specific structure of the locking buckle 40 and the clamping structure 41 cooperating with each other can also limit the clamping structure through a claw to achieve the mutual clamping of the locking buckle and the clamping structure. A feasible embodiment can be: when the handle rotates, the top contact part can move to the top contact claw with the rotation of the handle until the claw releases the clamping structure. In addition, the locking buckle 40 and the clamping structure 41 can be set to other feasible specific structures for mutual clamping, which are not specifically limited here.

[0085] In addition, when the locking buckle 40 and the clamping structure 41 are mutually clamped, the force to maintain the mutual clamping can be provided by elastic members or interference fit, etc., and no specific limitation is made here. If the method of providing the force to maintain the mutual clamping is different, the specific structure of the locking buckle 40 can also be implemented in different ways.

[0086] Taking the elastic member providing the mutual locking force as an example, a feasible specific structure of the locking buckle 40 can be as follows: Figure 4 and Figure 5 As shown, specifically: the locking buckle 40 also includes an elastic member 402, and the elastic force of the elastic member 402 acts on the abutment portion 401; in the process of the protruding portion 222 of the handle 22 being fitted with the side surface 100, the abutment portion 401 is pushed by the clamping plate 411 and retracts to overcome the elastic force of the elastic member 402; when the protruding portion 222 of the handle 22 is fitted with the side surface 100, the roller brush assembly 20 is installed into the floor brush base 10, and the abutment portion 401 is staggered with the clamping plate 411; the abutment portion 401 is clamped with the clamping plate 411 under the elastic force of the elastic member 402, so that the clamping structure 41 and the locking buckle 40 are clamped with each other.

[0087] In this structure, the elastic member 402 always provides elastic force for the abutting portion 401. When the roller brush assembly 20 is not installed in the floor brush base 10, the abutting portion 401 is always in the first position only under the elastic force of the elastic member 402. When the roller brush assembly 20 is installed, the first side surface 2220 of the extension portion 222 continuously approaches the side surface 100 of the floor brush base 10. During this process, the clamping plate 411 will abut against the abutting portion 401, so that the abutting portion 401 overcomes the elastic force of the elastic member 402 and moves until the roller brush assembly 20 is installed in the floor brush base 10.

[0088] When the roller brush assembly 20 is installed into the floor brush base 10, the abutment portion 401 is offset from the clamping plate 411, and the abutment portion 401 returns to the first position under the elastic restoring force of the elastic member 402, and engages with the clamping plate 411, thereby realizing the mutual clamping of the clamping structure 41 and the locking buckle 40.

[0089] When taking out the roller brush assembly 20, the user rotates the rotating member 23 in the direction away from the side surface 100, and the top contact portion 233 on the rotating member 23 will push the abutting portion 401 away from the first position, so that the engagement between the abutting portion 401 and the clamping plate 411 is released, and the clamping plate 411 is not blocked by the abutting portion 401, thereby releasing the mutual engagement between the locking buckle 40 and the clamping structure 41, and the locking buckle 40 withdraws from the disassembly and assembly path of the clamping structure 41.

[0090] Furthermore, the locking buckle 40 may further include a receiving cavity 403 ; the elastic member and the abutting portion 401 are received in the receiving cavity 403 , and the elastic member abuts the abutting portion 401 against the first end of the receiving cavity 403 .

[0091] In this embodiment, the elastic member 402 and the abutment portion 401 are accommodated in the accommodating cavity 403, so that the movable space of the abutment portion 401 is limited, which is convenient for regulating the specific position of the first position of the abutment portion 401 under the elastic force of the elastic member 402, so as to ensure that the abutment portion 401 can be snapped into place with the locking buckle 40 during the installation process of the roller brush assembly 20, thereby ensuring the snap-fit ​​effect.

[0092] More specifically, if Figure 4 As shown, the contact surfaces of the clamping plate 411 and the abutting portion 401 are also provided with an inclined surface 4011. In the process of the extension portion 222 of the handle 22 being fitted with the side surface 100 of the floor brush base 10, the clamping plate 411 on the clamping structure body 412 first abuts against the abutting portion 401, and under the action of the inclined surface 4011, the abutting portion 401 is pushed away during the fitting process, so that the abutting portion 401 overcomes the elastic force of the elastic member and retracts; when the extension portion 222 of the handle 22 is fitted with the side surface 100 of the floor brush base, the roller brush assembly 20 is installed into the floor brush base 10, the abutting portion 401 is staggered with the clamping plate 411, and under the action of the elastic restoring force of the elastic member, returns to the first end of the accommodating cavity 403 to enter the inner space of the clamping plate 411, so that the clamping structure 41 and the locking buckle 40 are mutually clamped.

[0093] In this specific clamping structure, the elastic member 402 always provides elastic force for the abutting portion 401, so that the abutting portion 401 is always in the first position when no external force is applied, that is, located at the first end of the accommodating cavity 403. When the roller brush assembly 20 is installed, in the process of the first side surface 2220 of the protruding portion 222 constantly approaching the side surface 100 of the floor brush base 10, the clamping plate 411 first abuts against the inclined surface 4011 of the abutting portion 401, and continuously presses the inclined surface 4011, so that the abutting portion 401 is pushed back into the accommodating cavity 403 under the action of the inclined surface 4011. When the first side surface 2220 of the extension portion 222 of the handle 22 fits into place with the side surface 100 of the floor brush base 10, the roller brush assembly 20 is installed into the floor brush base 10, the abutment portion 401 is offset from the clamping plate 411, and under the action of the tension of the elastic member 402, it returns to the first end of the accommodating cavity 403 and enters the inner space of the clamping plate 411, thereby realizing the mutual clamping of the clamping structure 41 and the locking buckle 40.

[0094] Corresponding to the structure in which the locking buckle 40 and the clamping structure 41 are clamped to each other by the abutting clamping plate 411, the top contact portion 233 can be set to a structure that has a matching relationship with the clamping plate 411, so that the top contact portion 233 directly acts on the abutting portion 401, pushing the abutting portion 401 back into the accommodating cavity 403 to release the clamping.

[0095] Specifically, the top contact portion 233 is configured as follows: the top contact portion 233 can be pushed into the inner space of the card plate 411 as the handle 231 rotates, abutting against the abutting portion 401, and overcoming the elastic force of the elastic member 402 to support the abutting portion 401; after the handle 231 rotates into place, the elastic member 402 completely pushes the abutting portion 401 out of the inner space of the card plate 411, so that the abutting portion 401 reaches the first position.

[0096] Furthermore, after the top contact portion 233 pushes the abutting portion 401 out of the inner space, in order to ensure that the abutting portion 401 will return to the inner space again during the disassembly process of the roller brush assembly with the first side surface 2220 away from the side surface 100 of the floor brush base 10, the top contact portion 233 is provided with a top supporting surface in contact with the clamping plate 411; when the top contact portion 233 is pushed into the inner space of the clamping plate 411 and the abutting portion 401 is completely pushed out of the inner space of the clamping plate 411, the gap between the top supporting surface of the top contact portion 233 and the clamping plate 411 is not enough to allow the abutting portion 401 to be pressed in.

[0097] The above describes in detail the locking buckle and the clamping method of the clamping structure. In the cleaning device provided in this embodiment, the rotating member 23 has a variety of different specific structures corresponding to different requirements, which are described in detail below.

[0098] In this embodiment, the rotating member 23 can be rotatably fixed on the extension portion 222 of the handle 22, and the top contact portion 233 is used to contact the locking buckle 40 to realize the release of the clamping connection. The top contact portion 233 can be set as a structure directly affected by the handle 231, such as the top contact portion 233 and the handle 231 can be set as one body, so that the top contact portion 233 rotates with the rotation of the handle 231; or the top contact portion 233 can also be set as a structure indirectly affected by the handle 231, such as the top contact portion 233 and the handle 231 are indirectly connected by wire, spring, etc., so that the top contact portion 233 transmits tension through the wire, spring, etc. under the rotation of the handle 231 to achieve movement in different directions.

[0099] In addition, the rotating member 23 may also be Figure 2 As shown, the specific configuration is as follows: the rotating member 23 includes a rotating shaft 232; the rotating member is rotatably mounted on the protruding portion 222 of the handle 22 via the rotating shaft 232, and the handle 231 is arranged in a position that can rotate outward; when the handle 231 is pulled to rotate outward around the rotating shaft 232, the top contact portion 233 rotates toward the side surface 100 accordingly.

[0100] In this embodiment, it is also possible to Figure 2As shown, a torsion spring 234 is provided between the handle 231 and the extension 222 of the handle 22; when no external force is applied, the force of the torsion spring 234 causes the handle 231 to fit with the extension 222 of the handle 22. Thus, when the roller brush assembly 20 is installed in the floor brush base 10, the handle 231 can always fit with the extension 222 of the handle 22, thereby preventing the position of the handle 231 from changing under the action of external force, causing the contact portion 233 to contact the locking buckle 40 and causing the locking buckle to be mislocked.

[0101] In addition, the handle 231 may also be provided with a structure that facilitates the operator to pull the handle 231 in accordance with the operation mode of the operator. Figure 5 As shown, a force boss 235 is provided at the end of the handle 231 away from the top contact portion 233, and a force space for the operator's operating part to enter is reserved between the force boss 235 and the side surface 100 of the floor brush base 10; the operator can apply a pulling force to the handle 231 through the force boss 235 to rotate it in the direction away from the side surface 100 of the floor brush base 10.

[0102] In addition, the handle 231 can also be set to different shapes, such as a U-shaped structure suitable for hand holding, or a circular ring suitable for passing through fingers for pulling, but no specific limitations are given here.

[0103] The cleaning device provided by the present application is introduced in detail above. In this cleaning device, the roller brush assembly is installed on the floor brush base through the locking buckle and the clamping structure, and a corresponding rotating member is provided for releasing the clamping state between the locking buckle and the clamping structure. When the user pulls the rotating member, the locking buckle and the clamping structure are automatically unlocked, and the locking buckle is withdrawn from the disassembly path of the clamping structure, or the clamping structure is withdrawn from the disassembly path of the locking buckle; in short, the user can directly pull the rotating member to pull out the roller brush assembly, thereby simplifying the disassembly steps of the cleaning assembly, thereby achieving the effect of saving time and effort, and improving the user experience.

[0104] The technical solution provided in the embodiment of the present application is described below in conjunction with specific application scenarios.

[0105] Application Scenario 1

[0106] When the user uses the cleaning device to clean the floor, when the roller brush assembly needs to be disassembled, the user rotates the rotating member in a direction away from the side surface of the floor brush base, so that the mutual engagement between the locking buckle and the clamping structure is released, and the locking buckle is withdrawn from the disassembly path of the clamping structure. After that, the roller brush assembly can be directly pulled out along the axial direction of the roller brush body to complete the disassembly process of the roller brush assembly.

[0107] Application Scenario 2

[0108] When the roller brush assembly needs to be reinstalled on the floor brush base, the roller brush assembly is installed on the floor brush base along the axial direction of the roller brush body. When the roller brush assembly is installed into the floor brush base, the locking buckle is located on the disassembly and assembly path of the clamping structure, and the locking buckle and the clamping structure are clamped with each other, thereby completing the installation process of the roller brush assembly and continuing the cleaning work.

[0109] Although the present application is disclosed as above in the form of a preferred embodiment, it is not intended to limit the present application.
