Description

Cleaning equipment Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] Taking floor scrubbers as an example, cleaning equipment involves dragging the brush back and forth using a hand handle. Because the handle is rigidly connected to the machine body, and to facilitate hand operation, the floor scrubber is relatively large. In low-ceilinged environments, users need to bend over or squat, resulting in a poor user experience.

[0003] To facilitate cleaning low-ceilinged spaces, some handles are designed to fold. However, the handle length is limited, requiring users to bend over, making them less suitable for users of different heights.

[0004] Current technology has also produced floor scrubbers that can be folded and extended, but they all use multiple structures to drive them, making operation very cumbersome. Therefore, the improvement effect of existing technologies is not obvious, and the user experience needs further improvement.

[0005] Utility Model Content

[0006] To address at least one of the aforementioned technical problems, this application provides a cleaning device with a bendable and extendable handle, allowing the operator to conveniently clean low spaces without bending over. Furthermore, the bendability and extendability of the handle are locked or unlocked using a single locking mechanism, making operation simple and quick, and improving the user experience.

[0007] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0008] A first aspect of this application provides a cleaning device, the cleaning device comprising: a body, a handle, a floor brush, and a locking mechanism; one end of the body is rotatably connected to the floor brush;

[0009] The handle includes a retractable section, a connecting section, and a gripping part. One end of the connecting section is connected to the other end of the body, and the other end of the connecting section is rotatably connected to the retractable section.

[0010] The locking mechanism has at least a locked position and an unlocked position relative to the handle;

[0011] When the locking mechanism is in the locked position, the locking mechanism locks the connecting section and the retractable section in an upright state, and locks the retractable section in a retracted state;

[0012] When the body is in the target state relative to the floor brush, the locking mechanism can switch to the unlocked position under the action of external force, so that the connecting section and the retractable section can rotate relative to each other, and the grip can extend and retract relative to the connecting section using the retractable section; wherein, the target state includes any one of the following: lying down state, switching from upright state to lying down state, and switching from lying down state to upright state.

[0013] In daily life, when using cleaning equipment, such as floor scrubbers, users often need to squat down and control the handle to clean low spaces. This cleaning method puts a burden on the user's legs, and after cleaning for a long time, the legs are especially prone to numbness, resulting in a poor user experience.

[0014] As a result, some foldable floor scrubbers have appeared on the market. While these scrubbers can indeed save some users from squatting down, they still require users to bend over to operate them. This shifts the burden to the lower back, and for some users with lower back problems, the user experience may not be as good as the old foldable models.

[0015] Based on this, this patent provides a solution that can be both folded and retracted, and it can achieve one-click folding and retraction. It should be understood that many current folding or retracting solutions are controlled by different control devices and cannot achieve integrated one-click control.

[0016] Specifically, when performing routine cleaning work (i.e., cleaning in non-low-ceilinged spaces), the locking mechanism can be locked, preventing relative rotation between the telescopic section and the connecting section, which remain upright. The telescopic section is retracted and cannot extend or retract. In this position, the operator can use the handle to tilt the machine body slightly relative to the ground brush, allowing for easy back-and-forth dragging of the brush behind the machine to clean the surface. After stopping cleaning, such as when changing the water supply, emptying the wastewater tank, or returning the machine to the base station for charging or self-cleaning, the locking mechanism can also be locked, with the machine body approximately perpendicular to the ground brush.

[0017] When cleaning low spaces such as under beds, sofas, and tables, the locking mechanism can be switched to the unlocked position. The retractable and connecting sections can rotate relative to each other, allowing the handle to bend to the desired angle. The retractable section can then extend the handle to the desired length. Finally, the rotating connection between the body and the floor brush allows the machine to lie flat. This eliminates the need to bend or squat, allowing the floor brush to be inserted into low spaces from a comfortable standing position for cleaning. It's understood that, in addition to bending and extending the handle when the machine is lying flat, the handle can also be folded and extended in any position transitioning between upright and lying flat, or vice versa.

[0018] The extendable section allows the handle to be adjusted to different lengths to suit operators of varying heights. The grip is where the operator holds the handle. The grip extends and retracts synchronously with the extendable section. This allows the grip to be raised when the machine body is in a flat position relative to the brush, enabling the operator to clean low spaces while standing.

[0019] Because this application uses the same locking mechanism to lock or unlock the retractability of the telescopic section and the rotatability between the telescopic section and the connecting section (i.e., the bendable function of the handle), when an external force triggers the locking mechanism to unlock, it can unlock both the bendable function and the telescopic function of the handle, thus achieving one-button control of folding and bending. This makes the operation simpler, more convenient, and faster, and improves the user experience.

[0020] Optionally, the retractable segment has at least two locking parts;

[0021] The locking mechanism can move to the locking part at different positions and connect with the locking part at the corresponding position, so that the handle can remain in a telescopic state at different lengths when the cleaning device is in a flat state.

[0022] The locking mechanism allows the handle to be locked at the desired length, preventing unwanted extension or retraction of the extendable section during cleaning. This ensures that the handle length remains in a retractable position that matches the operator's needs during cleaning in low-ceilinged spaces.

[0023] Optionally, the locking mechanism includes:

[0024] The first lock is used to lock or unlock the rotatable connection between the connecting segment and the retractable segment;

[0025] The second lock is used to lock or unlock the retractable state of the retractable segment;

[0026] During the process of switching the locking mechanism from the locked position to the unlocked position, the first lock unlocks before the second lock. After the first lock is unlocked, the connecting section and the retractable section can rotate relative to each other; after the second lock is unlocked, the retractable section can extend and retract.

[0027] After the first lock is unlocked, the second lock can remain unlocked, meaning the operator can choose to bend the handle without extending it. If the operator needs to extend the handle later, the second lock can be unlocked again to allow the handle to extend or retract independently.

[0028] Alternatively, the operator can unlock both the bendable and extendable functions of the handle in one step. In other words, the user can choose to unlock both bending and extension with a single click.

[0029] Therefore, by using the first and second locks, different folding or extension needs of operators can be met, improving the flexibility of using the cleaning equipment.

[0030] Optionally, under the action of an external force, the first lock moves relative to the second lock, so that the first lock switches between at least a triggered position and a non-triggered position relative to the second lock;

[0031] When the first lock is in the non-triggered position, the first lock is in the unlocked state, and the second lock is in the locked state;

[0032] When the first lock is in the triggered position, the first lock is connected to the second lock, and the first lock drives the second lock to switch to the unlocked state, so that the retractable segment can be retracted.

[0033] The first lock unlocking before the second lock can be achieved by the independent movement of the first lock relative to the second lock. For example, if the operator wants the handle to bend but not extend, the first lock can be controlled to move independently relative to the second lock to leave the locked position, that is, the first lock can be controlled to move from the locked state to the non-triggered position, and the first lock unlocks before the second lock. If the operator subsequently needs to extend the handle, the first lock can be controlled to move back to connect with the second lock, using the first lock to drive the second lock to unlock, thus achieving the extension and retraction of the handle independently.

[0034] Understandably, since the second lock is unlocked by the action of the first lock, if the second lock is not driven, the first lock cannot leave the locking part, and thus the second lock cannot unlock before the first lock.

[0035] If the operator wants to unlock the bending and extension functions with one click, they can control the first lock to move in one step to connect with the second lock. The movement of the first lock unlocks both the bending and extension functions of the handle.

[0036] A non-triggered position refers to the position where there is no contact between the first and second locks, or where, although there is contact between the first and second locks, the first lock cannot trigger the second lock to switch to the unlocked state. A non-triggered position can be any position where the first lock leaves the locked state but has not yet reached the triggered position.

[0037] Before the first lock leaves the locked state and reaches the trigger position, the first lock moves independently relative to the second lock. The unlocking process of the first lock is a synchronous movement of both.

[0038] Optionally, under the action of an external force, the movement of the first lock includes: moving, rotating, or a combination of moving and rotating.

[0039] Since the movement of the first lock is divided into two processes—individual movement and synchronous movement of the first and second locks—these two processes can employ the same movement method. For example, the first lock can move upwards in both processes. Alternatively, the first lock can employ different movement methods in the two processes. For instance, the first lock can rotate during its individual movement and move linearly upwards during the synchronous movement of the first and second locks.

[0040] This application does not limit the movement mode of the first lock. The first lock can achieve the purpose of the application by adopting a variety of movement modes, which makes the structure more flexible.

[0041] Optionally, when the retractable section is in the extended state and the cleaning device switches from the lying state to the upright state, the retractable section first rotates relative to the connecting section, and after rotating to the upright state, the gripping part then drives the retractable section to retract relative to the connecting section; or, the gripping part first drives the retractable section to retract relative to the connecting section, and then the retractable section rotates relative to the connecting section to the upright state.

[0042] When switching the cleaning equipment from a lying position (taking the extended section as an example) to an upright position, you can first return the handle to the upright position, and then return it to the retracted position; alternatively, you can first return the handle to the retracted position, and then return it to the upright position. In other words, a bent and extended handle represents one state of the cleaning equipment in its lying position, and returning it to the upright position means the handle is in an upright and retracted position. Furthermore, these two different operating methods can accommodate the different operating habits of different users.

[0043] Optionally, when the cleaning device switches from the upright state to the lying state, the retractable section first rotates to a bent state relative to the connecting section, and then the gripping part drives the retractable section to extend relative to the connecting section; or, the gripping part first drives the retractable section to extend relative to the connecting section, and then the retractable section rotates to a bent state relative to the connecting section.

[0044] When switching the cleaning equipment from an upright position to a lying position, you can first bend the handle and then extend it (if you need to extend the handle length); or you can first extend the handle and then bend it. These two different operating methods can meet the different operating habits of different operators.

[0045] Optionally, the locking mechanism further includes: a first elastic element, one end of which is fixed relative to the retractable section, and the other end of which is connected to the second lock; the first elastic element is used to provide an elastic force to restore the second lock to the locked state.

[0046] Under the elastic force provided by the first elastic element, the second lock can be restored to the locked state without external force. For example, when the second lock moves to a position aligned with a certain locking part, the first elastic element drives the second lock to cooperate with the locking part, and the second lock switches from the unlocked state to the locked state.

[0047] One end of the first elastic element can be fixed to the inner wall of the telescopic section, or to the first lock, or it can be fixed in other ways. The goal is to fix one end of the first elastic element relative to the telescopic section.

[0048] Optionally, the direction of movement of the second lock when switching between the unlocked and locked states is the first direction;

[0049] The direction of movement of the first lock and the direction in which the first lock drives the second lock to move synchronously are both the second direction. The second direction is parallel to the retractable section, and the first direction is perpendicular to the second direction.

[0050] The first lock has a first inclined surface, and the second lock has a second inclined surface. During the movement of the first lock, the first inclined surface can slide relative to the second inclined surface, so that the first lock drives the second lock to switch to the unlocked state.

[0051] The first direction can be horizontal, and the second direction can be vertical. During the upward movement of the first lock relative to the second lock, the first lock first switches from a locked state to an unlocked state. As the first lock continues to move upward, the first inclined plane gradually comes into contact with the second inclined plane. Utilizing the interaction between the first and second inclined planes, the second lock, under the force of the first lock, separates from the locked portion, and the second lock switches to the unlocked state.

[0052] The combination of the first and second inclined planes allows the second lock to switch from the locked state to the unlocked state without changing the original direction of movement of the first lock, ensuring the bendable and extendable functions of the one-button unlocking handle.

[0053] Optionally, the second lock has a first groove with its opening facing downwards, and the first lock has a first protrusion with its protrusion facing upwards. The first inclined surface is one side surface of the first protrusion, and the second inclined surface is part of the inner wall of the first groove; the first protrusion can be inserted into the first groove.

[0054] The first protrusion is inserted into the first groove through the opening at the bottom of the first groove. The multiple inner walls of the first groove can be used to fit against the multiple outer surfaces of the first protrusion, thereby improving the reliability of the connection between the first lock and the second lock, and making the synchronous movement of the first lock driving the second lock more stable and reliable.

[0055] Optionally, the first lock further has a downwardly protruding second protrusion, and the connecting segment has an upwardly opening second groove; when the first lock is in the locked state, the second protrusion is inserted into the second groove.

[0056] The second protrusion enters and exits the second groove through the opening at the top of the second groove. Since the opening of the second groove faces upward and the opening of the first groove faces downward, and the two are roughly aligned, as the second protrusion of the first lock moves upward after leaving the second groove, the first protrusion enters the first groove, resulting in a simple and compact structure.

[0057] Since the locking mechanism is located in the telescopic section and the second groove is located in the connecting section, when the second protrusion is inserted into the second groove, the first lock is in a locked state. By using the multiple inner walls of the second groove to fit against the multiple outer surfaces of the second protrusion, the relative movement between the telescopic section and the connecting section can be prevented, thus ensuring the stability of the upright state.

[0058] Optionally, the handle further includes a pivot, through which the retractable section can rotate relative to the connecting section; when the retractable section and the connecting section are in an upright state, the second lock is located above the first lock, and the pivot is located below the first lock.

[0059] Since the second groove is located on the connecting section and the second protrusion is located on the locking mechanism, neither of them is related to the pivot. Therefore, there is no need to open the second groove in the small space of the pivot. The volume of the second groove and the second protrusion can be larger, and the area of ​​the mating part of the second groove and the second protrusion is larger, which reduces the risk of the handle shifting in the upright state and improves the stability of the handle.

[0060] Optionally, the locking mechanism further includes: a second elastic member, one end of which is fixed relative to the telescopic section, and the other end of which is connected to the first lock; the second elastic member is used to provide an elastic force to restore the first lock to the locked state.

[0061] Under the elastic force provided by the second elastic element, the first lock can be restored to the locked state without external force. Taking a retractable section comprising a relatively retractable inner tube and an outer tube, with the locking part located in a locking groove or locking hole on the outer tube as an example (to be specifically mentioned below): When retracting the folding retractable handle, one can first straighten the handle to restore it to an upright position, then pull up the trigger (a trigger can be used as a form of trigger) and apply downward force to the handle, pressing the inner tube downwards into the bottom of the outer tube, thus locking the folding and retractable functions of the handle using the locking mechanism. Alternatively, a more user-friendly approach can be chosen: first press the inner tube to the bottom of the outer tube. At this point, the second protrusion of the first lock slides into contact with the second groove of the connecting section, and the second lock has already partially engaged in the locking hole or locking groove under the action of the first elastic element, locking the retractable function of the inner tube relative to the outer tube. Then, the operator lifts the handle until it is in a vertical position, and the first lock automatically slides into the second groove under the reset action of the second elastic element, thus locking the folding function.

[0062] One end of the second elastic element can be fixed to the inner wall of the telescopic section, or it can be fixed to another position on the telescopic section. The key is to ensure that one end of the second elastic element is fixed relative to the telescopic section.

[0063] Optionally, the telescopic section includes an inner tube and an outer tube sleeved outside the inner tube, the inner tube being telescopic relative to the outer tube; the outer tube is rotatably connected to the connecting section, the locking mechanism is capable of moving synchronously with the inner tube, the outer tube has at least two locking parts, each locking part including a locking groove or a locking hole, the second lock being at least partially capable of being inserted into the locking groove or locking hole to make the second lock in a locked state; when the first lock is in a locked state, the first lock is synchronously in a locked state.

[0064] If there are at least two locking parts, when the locking mechanism is in the locked position, the first lock is locked to the connecting section, and the second lock is connected to the bottommost locking part. The handle cannot be folded or extended. If only the first lock is unlocked subsequently, but the second lock is not, the handle can be folded but not extended. If both the first and second locks are unlocked, the inner tube can be pulled upwards. During this process, the second lock moves away from the bottommost locking part and towards the upper locking part. When the handle extends to the second-to-last locking part (counting upwards from the lowest point), the second lock can automatically lock with the second-to-last locking part under the elastic action of the first elastic element. If you do not want the second lock to be locked at the second-to-last locking part and want the handle to extend further, you can apply an external force to the trigger when the second lock leaves the bottommost locking part. Using the first lock to move the second lock away from the locking part, you can pull the inner tube upwards and directly lock the second lock at the desired third-to-last locking part (if any). Of course, you can also move the second lock upwards a shorter distance after it is locked with the second-to-last locking part to lock the second lock at the third-to-last locking part.

[0065] Optionally, the outer tube includes: a housing and a bushing, the bushing being fitted inside the housing, the inner tube being fitted inside the bushing, and the locking groove or the locking hole being provided in the bushing.

[0066] By placing the locking groove or the locking hole in the bushing, the retractable function can be locked, and the locking groove or locking hole can be covered by the outer shell, which can improve the simplicity of the handle's outer tube and thus improve the user experience.

[0067] Optionally, the handle further includes a trigger and a traction member; the trigger is located in the grip portion, and the two ends of the traction member are respectively connected to the trigger and the locking mechanism;

[0068] The trigger element drives the locking mechanism to switch between the unlocked position and the trigger position via the traction element.

[0069] The grip is where the operator holds the control handle, and the trigger is the component that receives external force. By placing the trigger on the grip, closer to the hand, it is easier to apply external force to the traction component with one hand while holding the handle, thus enabling one-handed operation to switch the locking mechanism between the unlocked and locked positions.

[0070] A second aspect of this application provides a cleaning device, the cleaning device comprising: a body, a handle, a floor brush, and a locking mechanism; one end of the body is rotatably connected to the floor brush;

[0071] The handle is retractable and rotatably connected to the other end of the body;

[0072] The locking mechanism has at least a locked position and an unlocked position relative to the handle;

[0073] When the locking mechanism is in the locked position, the locking mechanism locks the handle to the body in an upright state and locks the handle in a retracted state;

[0074] When the body is in the target state relative to the floor brush, the locking mechanism can be in the unlocked position, the handle can rotate relative to the body, and the handle can extend and retract; wherein, the target state includes any one of the following: lying down state, switching from upright state to lying down state, and switching from lying down state to upright state.

[0075] The second aspect embodiment differs from the aforementioned first aspect embodiment in that: in the first aspect embodiment, the handle itself is bendable, enabling the cleaning device to be foldable. In the second aspect embodiment, the handle itself is not bendable, but the handle is bendable relative to the body. Therefore, the handle of the second aspect embodiment is equivalent to the telescopic section of the first aspect embodiment, and the body of the second aspect embodiment is equivalent to a combination of the body and connecting section of the first aspect embodiment; the remaining structures are the same as those of the first aspect embodiment. Therefore, the second aspect embodiment has the same technical effects as the first aspect embodiment, and will not be described again here. Attached Figure Description

Detailed Implementation

[0090] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0091] In the description of this application, the terms "length", "height", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this application and do not indicate that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. In other words, they should not be construed as limitations on this application.

[0092] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating the relative importance of the indicated features or the number of indicated technical features. Therefore, a feature defined as "first" or "second" can explicitly include at least one of those features. In the description of this application, "multiple" means at least two, such as two, three, etc.

[0093] The cleaning equipment described in this application includes, but is not limited to, floor scrubbers, electric mops, steam mops, and sweeper-mop combos. For ease of description, a floor scrubber will be used as an example to provide a detailed description of the cleaning equipment below.

[0094] As shown in Figure 1, a floor scrubber generally includes a body 200, a handle 100, and a floor brush 500. During the cleaning process, the operator or user holds the machine on the body 200 and moves the floor brush 500 by swinging the body 200, causing the floor brush 500 to rub against the surface to be cleaned. Surfaces to be cleaned include floors, carpets, walls, tabletops, etc.

[0095] Optionally, the floor scrubber may also include a wastewater tank 300, which is used to collect dirt from the cleaning process, typically a solid-liquid mixture.

[0096] The cleaning equipment may also include a suction device that provides negative pressure, under which dirt on the surface to be cleaned is sucked into the wastewater tank 300.

[0097] Optionally, the floor scrubber may also include a clean water tank 400, which can provide cleaning liquid to the roller brush to wet the roller brush, so that the roller brush can wet the stains on the surface to be cleaned during the cleaning process, reduce the adhesion of the stains, and improve the cleaning effect.

[0098] The body 200 can rotate relative to the brush 500. Furthermore, the body 200 can switch between an upright position as shown in Figure 1, a lying position as shown in Figure 2, and any position in between.

[0099] The concept of this application is to utilize the flat position of the body 200 relative to the brush 500, and to make the handle 100 foldable and retractable to reduce the height of the body 200. The body 200 can at least partially extend into low spaces, so that users can clean low spaces without bending over or squatting, or even in a more comfortable standing posture, thereby improving cleaning efficiency and user experience.

[0100] Furthermore, this application simplifies the operation of the folding and bending functions of the handle 100, enabling both folding and bending functions to be unlocked with a single button, and allowing bending without extension or retraction. The extension and retraction of the handle 100 can also adapt to the height needs of different users, further improving the user experience. The application concept will be described below with reference to specific embodiments.

[0101] Example 1

[0102] Based on the foregoing description and Figures 1 to 9, the cleaning equipment of this embodiment will be described in detail.

[0103] As shown in Figure 1, the cleaning equipment includes: a body 200, a handle 100, a floor brush 500, and a locking mechanism 130 (see Figure 3); one end of the body 200 is rotatably connected to the floor brush 500; the handle 100 includes a telescopic section 110 and a connecting section 120, one end of the connecting section 120 is connected to the other end of the body 200, and the other end of the connecting section 120 is rotatably connected to the telescopic section 110; the locking mechanism 130 has at least a locked position (see Figures 6 and 7) and an unlocked position (see Figure 8) relative to the handle 100. The locked position is used to lock the bendable (also called foldable) function of the handle 100 and the telescopic function of the telescopic section. The unlocked position is used to unlock the bendable function of the handle 100 and the telescopic function of the telescopic section.

[0104] When the locking mechanism 130 is in the locked position, it locks the connecting section 120 and the retractable section 110 in an upright state and locks the retractable section 110 in a retracted state. When the body 200 is in the target state relative to the brush 500, the locking mechanism 130 can switch to the unlocked position under the action of external force, so that the connecting section 120 and the retractable section 110 can rotate relative to each other, and the retractable section 110 can extend and retract. The target state includes any one of the following: lying down, switching from an upright state to a lying down state, and switching from a lying down state to an upright state.

[0105] When the cleaning equipment is performing routine cleaning work (i.e., cleaning work in non-low-ceiling spaces), the locking mechanism 130 can be locked, preventing the telescopic section 110 and connecting section 120 from rotating relative to each other, and keeping them upright. When the telescopic section 110 is retracted and cannot be extended or retracted, the body 200 can be tilted slightly relative to the ground brush 500 using the operating handle 100, allowing the operator to easily drag the ground brush 500 back and forth behind the cleaning equipment to clean the surface. After cleaning is stopped, such as when changing the water in the cleaning equipment, emptying the wastewater tank 300, or returning the cleaning equipment to the base station for charging or self-cleaning, the locking mechanism 130 can also be locked, with the body 200 approximately perpendicular to the ground brush 500.

[0106] When cleaning low spaces such as under beds, sofas, and tables, the locking mechanism 130 can be switched to the unlocked position. The retractable section 110 and connecting section 120 can rotate relative to each other, allowing the handle 100 to be bent to the desired angle. The retractable section 110 can then extend the handle 100 to the desired length. The rotatable connection between the body 200 and the floor brush 500 allows the body 200 to lie flat. This allows the floor brush 500 to be inserted into low spaces without bending or squatting, achieving cleaning in a comfortable standing position. It is understood that, in addition to bending and extending the handle 100 when the body 200 is lying flat, the handle 100 can also be folded and extended in any position transitioning from upright to lying flat, or vice versa.

[0107] By utilizing the telescopic nature of the telescopic section 110, the handle 100 can be adjusted to different lengths to suit operators of different heights. In some alternative embodiments, the handle 100 also includes a grip portion 113 as shown in FIG. 4. The grip portion 113 can extend and retract relative to the connecting section 120 via the telescopic section 110. The grip portion 113 is the part where the operator holds the handle 100. The grip portion 113 can extend and retract synchronously with the telescopic section 110, so that when the machine body 200 is in a flat position relative to the brush, the extension of the telescopic section 110 can raise the height of the grip portion 113, allowing the operator to clean low spaces while standing.

[0108] Because this application uses the same locking mechanism 130 to lock or unlock the retractability of the retractable section 110 and the rotatability (i.e., the bendable function of the handle 100) between the retractable section 110 and the connecting section 120, when an external force triggers the locking mechanism 130 to unlock, it can unlock both the bendable function and the retractable function of the handle 100, thus achieving one-button control of folding and bending. The operation is simpler, more convenient, and faster, improving the user experience.

[0109] The connecting section 120 is detachably connected to the body 200, which allows for the disassembly and assembly of the handle 100, facilitating the transportation or maintenance of the cleaning equipment.

[0110] In some alternative embodiments, the telescopic section 110 has at least two locking parts 1123; the locking mechanism 130 is movable to the locking parts 1123 at different positions and connected to the locking parts 1123 at the corresponding positions so that the handle 100 can remain in a telescopic state at different lengths when the cleaning device is in a flat position.

[0111] The locking part 1123 can lock the handle 100 at the required length, preventing the telescopic section 110 from extending or retracting undesirably during the cleaning process, so that the length of the handle 100 remains in a telescopic state that matches the operator during the cleaning process in low-ceilinged spaces.

[0112] In some optional embodiments, as shown in FIG3, the locking mechanism 130 includes: a first lock 131 and a second lock 132. The first lock 131 is used to lock or unlock the rotatable connection between the connecting segment 120 and the retractable segment 110; the second lock 132 is used to lock or unlock the retractable state of the retractable segment 110. During the process of switching the locking mechanism 130 from the locked position to the unlocked position, the first lock 131 unlocks before the second lock 132. After the first lock 131 is unlocked, the connecting segment 120 and the retractable segment 110 can rotate relative to each other. After the second lock 132 is unlocked, the retractable segment 110 can extend and retract.

[0113] After the first lock 131 is unlocked, the second lock 132 does not need to be unlocked. That is, the first lock 131 and the second lock 132 do not need to be unlocked synchronously. In this case, the locking mechanism 130 is neither in the locked position nor the unlocked position, but in a partially locked state. In other words, the operator can choose to bend the handle 100 without extending it. Furthermore, if the operator needs to extend the handle 100 later, they can unlock the second lock 132 again, allowing the handle 100 to extend independently.

[0114] Alternatively, the operator can unlock both the bendable and extendable functions of the handle 100 in one step. In other words, the user can choose to unlock both bending and extension with a single click.

[0115] Therefore, by utilizing the first lock 131 and the second lock 132, different folding or extension needs of the operator can be met, thereby improving the flexibility of the cleaning equipment.

[0116] In some alternative embodiments, under the action of an external force, the first lock 131 moves relative to the second lock 132, so that the first lock 131 switches between at least a triggered position and a non-triggered position relative to the second lock 132; when the first lock 131 is in the non-triggered position, the first lock 131 is in the unlocked state and the second lock 132 is in the locked state; when the first lock 131 is in the triggered position shown in FIG8, the first lock 131 is connected to the second lock 132, and the first lock 131 drives the second lock 132 to switch to the unlocked state, so that the retractable section 110 can be retracted.

[0117] The first lock 131 can unlock before the second lock 132 by moving the first lock 131 independently relative to the second lock 132. For example, if the operator wants the handle to bend but not extend, the first lock 131 can be moved independently relative to the second lock 132 to leave the locked position, meaning the first lock 131 unlocks before the second lock 132. If the operator subsequently needs to extend the handle 100, the first lock 131 can be moved again to connect with the second lock 132, using the first lock 131 to unlock the second lock 132, thus enabling the handle 100 to extend independently.

[0118] If the operator wants to unlock the bending and extension functions with one click, the first lock 131 can be moved to connect with the second lock 132 in one step. The movement of the first lock 131 unlocks both the bending and extension functions of the handle 100.

[0119] A non-triggered position refers to the position where there is no contact between the first lock 131 and the second lock 132, or, although there is contact between the first lock 131 and the second lock 132, the first lock 131 cannot drive the second lock 132 to the unlocked state. A non-triggered position can be any position where the first lock 131 leaves the locked state but has not yet reached the triggered position.

[0120] For example, the non-triggered position of the first lock 131 can be located between the positions shown in Figures 7 and 8. It can also be as shown in Figure 9.

[0121] Before the first lock 131 leaves the locked state and reaches the trigger position, the movement of the first lock 131 relative to the second lock 132 is independent. The unlocking process of the first lock 131 is a synchronous movement of the two.

[0122] In some alternative embodiments, the movement of the first lock 131 under the action of an external force includes: moving, rotating, or a combination of moving and rotating.

[0123] Since the movement of the first lock 131 is divided into two processes—individual movement and synchronous movement of the first lock 131 and the second lock 132—these two processes can employ the same movement method. For example, the first lock 131 can move upwards in both processes. Alternatively, the first lock 131 can employ different movement methods in the two processes. For instance, the first lock 131 can rotate during its individual movement, while it can move linearly upwards during the synchronous movement of the first lock 131 and the second lock 132.

[0124] In the embodiments illustrated in this application, the movement of the first lock 131 is a vertical linear movement. In other embodiments, the first lock 131 can be rotatably disposed within the telescopic section 110 via a shaft-like structure. Different rotation angles of the first lock 131 can be used to achieve independent movement of the first lock 131 relative to the second lock 132, or the first lock 131 driving the second lock 132 to move synchronously. It is understood that the movement of the first lock 131 from the locked state to the unlocked state can also be designed as rotation, while the synchronous movement of the first lock 131 driving the second lock 132 can be designed as movement.

[0125] This application does not limit the movement mode of the first lock 131. The first lock 131 can adopt a variety of movement modes to achieve the purpose of the application, so the structure is more flexible.

[0126] In some alternative implementations, when the retractable section is in the extended state and the cleaning device switches from a lying state to an upright state, the retractable section first rotates relative to the connecting section, and after rotating to the upright state, the gripping part then drives the retractable section to retract relative to the connecting section; or, the gripping part first drives the retractable section to retract relative to the connecting section, and then the retractable section rotates relative to the connecting section to the upright state.

[0127] When switching the cleaning equipment from a lying position (taking the extended section as an example) to an upright position, you can first return the handle to the upright position, and then return it to the retracted position; alternatively, you can first return the handle to the retracted position, and then return it to the upright position. In other words, a bent and extended handle represents one state of the cleaning equipment in its lying position, and returning it to the upright position means the handle is in an upright and retracted position. Furthermore, these two different operating methods can accommodate the different operating habits of different users.

[0128] In some alternative implementations, when the cleaning device switches from an upright state to a lying state, the retractable section first rotates to a bent state relative to the connecting section, and then the gripping part drives the retractable section to extend relative to the connecting section; or, the gripping part first drives the retractable section to extend relative to the connecting section, and then the retractable section rotates to a bent state relative to the connecting section.

[0129] When switching the cleaning equipment from an upright position to a lying position, you can first bend the handle and then extend it (if you need to extend the handle length); or you can first extend the handle and then bend it. These two different operating methods can meet the different operating habits of different operators.

[0130] In some alternative embodiments, as shown in Figures 3, 7 and 10, the locking mechanism 130 further includes: a first elastic member 133, one end of which is fixedly connected to the telescopic section 110, and the other end of which is connected to the second lock 132; the first elastic member 133 is used to provide an elastic force to restore the second lock 132 to the locked state.

[0131] Under the elastic force provided by the first elastic element 133, the second lock 132 can be restored to the locked state without external force. For example, when the second lock 132 moves to a position aligned with a certain locking part 1123, the first elastic element 133 drives the second lock 132 to cooperate with the locking part 1123, and the second lock 132 switches from the unlocked state to the locked state.

[0132] One end of the first elastic element 133 can be fixed to the inner wall of the telescopic section 110, or to the first lock 131, or it can be fixed in other ways. The goal is to fix one end of the first elastic element 133 relative to the telescopic section 110.

[0133] Figure 3 exemplarily shows that the first elastic element 133 is a compression spring. In other alternative implementations, the first elastic element 133 can also be a tension spring, a torsion spring, or a leaf spring, etc. However, it is not limited to these.

[0134] In some optional embodiments, as shown in FIG8, the direction of movement of the second lock 132 when switching between the unlocked state and the locked state is the first direction; the direction of movement of the first lock 131, and the direction in which the first lock 131 drives the second lock 132 to move synchronously, are both the second direction. The second direction is parallel to the retractable section 110, and the first direction is perpendicular to the second direction.

[0135] As shown in Figures 3, 7 and 8, the first lock 131 has a first inclined surface 1313 and the second lock 132 has a second inclined surface 1323. During the movement of the first lock 131, the first inclined surface 1313 can slide relative to the second inclined surface 1323, so that the first lock 131 drives the second lock 132 to switch to the unlocked state.

[0136] Referring to Figure 8, the first direction can be horizontal, and the second direction can be vertical. Using the force component of the first lock 131 moving upwards, the second lock 132 moves horizontally to the left to the position shown in Figure 8, thus unlocking the second lock 132. It can be understood that if the second lock 132 locks again, it can move horizontally to the right from the position shown in Figure 8.

[0137] As the first lock 131 moves upward relative to the second lock 132, the first lock 131 switches from a locked state to an unlocked state. As the first lock 131 continues to move upward, the cooperation between the first inclined surface 1313 and the second inclined surface 1323 causes the second lock 132 to separate from the locking part 1123 under the force of the first lock 131, and the second lock 132 also switches to the unlocked state.

[0138] The inclined surface combination of the first inclined surface 1313 and the second inclined surface 1323 can drive the second lock 132 from the locked state to the unlocked state without changing the original direction of movement of the first lock 131, thus ensuring the bendable and telescopic functions of the one-button unlocking handle 100.

[0139] In some alternative embodiments, the second lock 132 has a first groove 1322 with the opening facing downward, the first lock 131 has a first protrusion 1311 with the protrusion facing upward, the first inclined surface 1313 is one side surface of the first protrusion 1311, and the second inclined surface 1323 is part of the inner wall of the first groove 1322; the first protrusion 1311 can be inserted into the first groove 1322.

[0140] The first protrusion 1311 is inserted into the first groove 1322 from the bottom outlet of the first groove 1322. The multiple inner walls of the first groove 1322 can be used to fit with the multiple outer surfaces of the first protrusion 1311, thereby improving the reliability of the connection between the first lock 131 and the second lock 132, and making the synchronous movement of the first lock 131 driving the second lock 132 more stable and reliable.

[0141] In some alternative embodiments, the first lock 131 also has a downwardly protruding second protrusion 1312, and the connecting segment 120 has an upwardly opening second groove 121; when the first lock 131 is in the locked state, the second protrusion 1312 is inserted into the second groove 121.

[0142] The second protrusion 1312 enters and exits the second groove 121 through the top opening of the second groove 121. Since the opening of the second groove 121 faces upward and the opening of the first groove 1322 faces downward, and the two are roughly aligned, as the second protrusion 1312 of the first lock 131 moves upward after leaving the second groove 121, the first protrusion 1311 enters the first groove 1322, resulting in a simple and compact structure.

[0143] Since the locking mechanism 130 is located in the telescopic section 110 and the second groove 121 is located in the connecting section 120, when the second protrusion 1312 is inserted into the second groove 121, the first lock 131 is in a locked state. By using the multiple inner walls of the second groove 121 to fit against the multiple outer surfaces of the second protrusion 1312, the relative movement between the telescopic section 110 and the connecting section 120 can be prevented, thus ensuring the stability of the upright state.

[0144] In some alternative embodiments, the handle 100 further includes a pivot 150, through which the telescopic section 110 is rotatable relative to the connecting section 120; when the telescopic section 110 and the connecting section 120 are in an upright state, the second lock 132 is located above the first lock 131, and the pivot 150 is located below the first lock 131.

[0145] Since the second groove 121 is located on the connecting section 120 and the second protrusion 1312 is located on the locking mechanism 130, both of which are independent of the rotating shaft 150, there is no need to open the second groove 121 in the small space of the rotating shaft 150. The volume of the second groove 121 and the second protrusion 1312 can be larger, and thus the area of ​​the mating part of the second groove 121 and the second protrusion 1312 is larger, thereby reducing the risk of the handle 100 shifting in the upright state and improving the stability of the handle 100.

[0146] In some alternative embodiments, the locking mechanism 130 further includes a second elastic member 134, one end of which is fixed to the telescopic section 110, and the other end of which is connected to the first lock 131; the second elastic member 134 is used to provide an elastic force that restores the first lock 131 to the locked state.

[0147] Under the elastic force provided by the second elastic element 134, the first lock 131 can be restored to the locked state without external force.

[0148] Figure 3 exemplarily shows the second elastic element 134 as a compression spring. In other alternative implementations, the second elastic element 134 can also be a tension spring, torsion spring, or sheet spring, etc. However, it is not limited to these.

[0149] The following description, in conjunction with Figures 8 to 11, uses an example where the retractable section 110 includes a retractable inner tube 111 and an outer tube 112, and the locking part 1123 is a locking groove or locking hole provided in the outer tube 112 (to be specifically mentioned below): When retracting the folding retractable handle 100, you can first straighten the handle 100 to restore it to an upright state, then pull up the trigger 114 (the trigger can be one form of the trigger 114) and apply a downward force to the handle 100, pressing the inner tube 111 downward into the bottom of the outer tube 112, and using the locking mechanism 130 to lock the folding and retractable functions of the handle 100. Alternatively, a more user-friendly approach can be chosen: first, press the inner tube 111 to the bottom of the outer tube 112. At this point, the second protrusion 1312 of the first lock 131 slides into contact with the second groove 121 of the connecting section 120, while the second lock 132 is partially engaged in the locking hole or locking groove under the action of the first elastic member 133. The retractable function of the inner tube 111 relative to the outer tube 112 is locked. Then, the operator lifts the handle 100 until it is in a vertical position. The first lock 131 slides into the second groove 121 under the reset action of the second elastic member 134, thus locking the foldable function.

[0150] One end of the second elastic member 134 can be fixed to the inner wall of the telescopic section 110, or it can be fixed to other positions of the telescopic section 110. The goal is to ensure that one end of the second elastic member 134 is fixed to the telescopic section 110.

[0151] In some alternative embodiments, as shown in FIG9, the telescopic section 110 includes an inner tube 111 and an outer tube 112 sleeved outside the inner tube 111. The inner tube 111 is telescopic relative to the outer tube 112. The outer tube 112 is rotatably connected to the connecting section 120. The locking mechanism 130 can move synchronously with the inner tube 111. The outer tube 112 has at least two locking parts 1123. The locking parts 1123 include locking grooves or locking holes. The second lock 132 can be at least partially inserted into the locking grooves or locking holes so that the second lock 132 is in a locked state. When the second lock 132 is in a locked state, the first lock 131 is simultaneously in a locked state.

[0152] As shown in Figure 6, a grip 113 can be provided at the top of the inner tube 111, and the outer tube 112 and the connecting section 120 are rotatably connected via a pivot 150. The operator can pull the inner tube 111 out from inside the outer tube 112 by pulling the grip. At this time, the handle 100 extends, and the telescopic section 110 is in an extended state. When the operator presses the inner tube 111 into the outer tube 112, the handle 100 shortens, and the telescopic section 110 can switch to a retracted state. In this case, the inner tube 111 slides relative to the inner wall of the outer tube 112. This telescopic design is simple in structure and has good reliability.

[0153] It is understandable that the telescopicity of the telescopic section 110 can also be achieved in other ways. For example, the inner tube 111 and the outer tube 112 can be threaded together. Alternatively, the locking mechanism 130 can be installed on the outer tube 112, and the inner tube 111 can be rotatably connected to the connecting section 120 via a pivot 150, allowing the operator to extend or retract the outer tube 112 by pushing or pulling it.

[0154] If the locking part 1123 includes at least two, then when the locking mechanism 130 is in the locked position, the first lock 131 is locked to the connecting section 120, and the second lock 132 is connected to the bottommost locking part 1123, and the handle 100 cannot be folded or extended. If only the first lock 131 is subsequently unlocked, while the second lock 132 remains unlocked, the handle 100 can be folded but not extended; if both the first lock 131 and the second lock 132 are unlocked, the inner tube 111 can be pulled upwards. During this process, the second lock 132 moves away from the bottommost locking part 1123 and towards the upper locking part 1123. When the handle 100 extends to the second-to-last (counting upwards from the lowest point) locking part 1123, under the elastic action of the first elastic member 133, the second lock 132 can automatically... The second lock 132 is locked to the penultimate locking part 1123. If you do not want the second lock 132 to be locked to the penultimate locking part 1123 and want the handle 100 to extend further, you can apply external force to the trigger 114 when the second lock 132 leaves the bottom locking part 1123. At the same time, the first lock 131 pulls the second lock 132 to avoid the locking part 1123 and pulls the inner tube 111 upward, directly locking the second lock 132 to the desired penultimate locking part 1123 (if any). Of course, you can also move the second lock 132 upward a shorter distance after it is locked to the penultimate locking part 1123, so that the second lock 132 is locked to the penultimate locking part 1123.

[0155] In some alternative embodiments, as shown in FIG11, the outer tube 112 includes: a housing 1122 and a bushing 1121, the bushing 1121 being fitted inside the housing 1122, the inner tube 111 being fitted inside the bushing 1121, and a locking groove or locking hole being provided in the bushing 1121.

[0156] By setting the locking slot or locking hole in the bushing 1121, the retractable function can be locked, and the locking slot or locking hole can be covered by the outer shell 1122, which can improve the simplicity of the outer tube 112 of the handle 100 and thus improve the user experience.

[0157] It is understandable that the outer tube 112 may not be divided into the outer shell 1122 and the bushing 1121, but may be formed as a separate tube. In this way, the locking hole or locking groove is provided on the outer tube 112, and the locking hole and the connection between the second lock 132 and the locking hole can be observed from the outside.

[0158] In some alternative embodiments, as shown in FIG12, the handle 100 further includes a trigger 114 and a traction member 140; the trigger 114 is located in the grip portion 113, and the two ends of the traction member 140 are respectively connected to the trigger 114 and the locking mechanism 130; the trigger 114 drives the locking mechanism 130 to switch between the unlock position and the trigger position through the traction member 140.

[0159] As shown in Figure 3, the handle 100 also includes a third elastic element 115. The third elastic element 115 provides elastic force for the trigger element 114 to reset, facilitating the switching of the trigger element 114 between different positions to match the locked and unlocked positions of the locking mechanism 130. When no external force is applied to the trigger element 114, the first lock 131 and the second lock 132 are in a separated state, or the first lock 131 has no driving effect on the second lock 132, and the trigger element 114 cannot drive the first lock 131 to move through the traction element 140. When an external force is applied to the trigger element 114, the trigger element 114 can drive the locking mechanism 130 to switch from the locked position to the unlocked position, or switch to the semi-unlocked state as described above, through the traction element 140. After the external force is removed, the first lock 131 and the second lock 132 return to the separated state, or return to the state where the first lock 131 has no driving effect on the second lock 132.

[0160] The third elastic element 115 can be a compression spring, tension spring, torsion spring, or sheet spring, etc., but is not limited to these.

[0161] The top of the traction member 140 can be connected to a trigger (an optional form of the trigger member 114), and the bottom of the traction member 140 can be connected to the first lock 131.

[0162] The trigger 114 is a component that receives external force. The trigger 114 is located in the grip part 113, closer to the hand, which makes it easier to apply external force to the traction member 140 with one hand while holding the handle 100. This allows the locking mechanism 130 to be switched between the unlocked and locked positions with one hand, making the operation simple, convenient and quick.

[0163] The traction component 140 can be a wire rope or a tie rod, but it is not limited to these.

[0164] Example 2

[0165] A cleaning device includes: a body 200, a handle 100, a floor brush 500, and a locking mechanism 130; one end of the body 200 is rotatably connected to the floor brush 500.

[0166] The handle 100 is retractable and rotatably connected to the other end of the body 200;

[0167] The locking mechanism 130 has at least a locked position and an unlocked position relative to the handle 100;

[0168] When the locking mechanism 130 is in the locked position, the locking mechanism 130 locks the handle 100 and the body 200 in an upright state and locks the handle 100 in a retracted state;

[0169] When the body 200 is in the target state relative to the brush 500, the locking mechanism 130 can be in the unlocked position, the handle 100 can rotate relative to the body 200, and the handle 100 can extend and retract; wherein, the target state includes any one of the following: lying down state, switching from upright state to lying down state, and switching from lying down state to upright state.

[0170] The difference between Embodiment 2 and Embodiment 1 is as follows: In Embodiment 1, the handle 100 itself is bendable, and the folding of the handle 100 enables the cleaning device to be foldable. In Embodiment 2, the handle 100 itself is not bendable, but the handle 100 is bendable relative to the body 200. Therefore, the handle 100 of Embodiment 2 is equivalent to the telescopic section 110 of Embodiment 1, and the body 200 of Embodiment 2 is equivalent to the combination of the body 200 and the connecting section 120 in Embodiment 1. The remaining structures are the same as in Embodiment 1.

[0171] Example 2 has the same technical effects as Example 1, and will not be described again here.

[0172] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0173] In the description of this specification, references to "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
