Description

Technical Field

[0001] This invention belongs to the field of cleaning technology, specifically relating to a locking device, a base station, and cleaning equipment. Background Technology

[0002] Cleaning equipment, such as floor scrubbers, is increasingly being used for household floor cleaning due to its advantages, including ease of use and effective cleaning. Floor scrubbers are typically equipped with a base station. After completing a cleaning task, the scrubbing head is placed on the base station for further cleaning and / or charging.

[0003] Once connected to a base station, the floor scrubber can collect wastewater and solid waste from the scrubber and discharge it to the base station, reducing maintenance work for users. However, if the floor scrubber is removed by external force during the waste collection process, the discharge operation may be interrupted, causing waste to leak from the corresponding discharge ports on both the scrubber and the base station. To prevent this leakage, a mechanical locking system is typically used to secure the floor scrubber and base station together after connection.

[0004] In existing technologies, mechanical locking is achieved by using a drive motor to move the locking element. This locking element can be a conventional structure such as a hook. However, if an unexpected power outage occurs while the floor scrubber and base station are still connected after completing their cleaning operation, and the user needs to separate them, the locking element will remain locked, preventing separation, because the drive motor cannot operate.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is how to separate the cleaning equipment and the base station in the event of an unexpected power outage when the cleaning equipment and the base station are still connected after the sewage discharge operation is completed, so as not to affect the use of the cleaning equipment.

[0023] Optionally, in the above-described locking device, the first target device has a track that slides with the sliding block, and the track is distributed along the installation direction of the first target device and the second target device.

[0024] Optionally, in the above-described locking device, the locking part has a first guide surface, which is adapted to guide the installation direction of the first target device and the second target device;

[0025] In the installation direction of the first target device and the second target device, the first guide surface is arranged from top to bottom in the direction of the first magnetic adsorption component.

[0026] Optionally, in the above-described locking device, the locking part further has a second guide surface, which is disposed opposite to the first guide surface;

The magnetic adsorption mechanism includes a first magnetic adsorption element electrically connected to the first target device, and a second magnetic adsorption element connected to the locking mechanism and adsorbing with the first magnetic adsorption element. The locking mechanism is installed on the first target device and at least partially protrudes from the first target device, so that when the second target device is installed with the first target device, the at least part of the locking mechanism protruding from the first target device can connect the first target device and the second target device. When the first magnetic adsorption element is powered on, it adsorbs with the second magnetic adsorption element to lock the device. The mechanism locks the first and second target devices, preventing the second target device from separating from the first target device under external force. This ensures the normal operation of the first and second target devices during sewage discharge, preventing the possibility of sewage leakage. When the first magnetic adsorption component is not powered on, it can separate from the second magnetic adsorption component to release the locking mechanism, allowing the first and second target devices to separate under external force. This ensures that the first and second target devices can still separate in the event of an unexpected power outage, without affecting their use and improving efficiency. Attached Figure Description

Detailed Implementation

[0054] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0055] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0056] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0057] Example 1

[0058] After completing its work, the cleaning equipment is placed on the base station for cleaning or charging, with cleaning and charging occurring simultaneously. Charging involves the base station charging the cleaning equipment's battery pack; the cleaning process includes self-cleaning and general cleaning.

[0059] The self-cleaning function of the cleaning equipment is as follows: the cleaning component of the cleaning device rotates and delivers cleaning fluid to the cleaning component to rinse the surface dirt of the cleaning component, thereby achieving the cleaning effect.

[0060] The cleaning process for the cleaning equipment involves storing dirt in its own wastewater tank during operation. When the cleaning equipment is installed on a base station, the wastewater tank can be connected to the base station to discharge the dirt into the base station's recycling bin, thus cleaning the equipment.

[0061] In the prior art, when the cleaning equipment is performing a sewage discharge operation, if it encounters an external force (such as a force applied by a person, or the cleaning equipment tipping over due to an unstable connection between the cleaning equipment and the base station), the cleaning equipment will separate from the base station, exposing the sewage discharge port of the cleaning equipment and the connection port 2 of the base station. Dirt will flow out from the sewage discharge port and the connection port 2 to the outside of the cleaning equipment and the base station, thereby causing dirt leakage.

[0062] Please see Figure 1 , Figure 2 and Figure 3 To prevent the aforementioned phenomenon, this embodiment provides a locking device 4, suitable for installation on a first target device 10, which is adapted to be connected to a second target device 20. When the first target device 10 and the second target device 20 are connected, the locking device 4 locks the first target device 10 and the second target device 20 together to prevent them from detaching. In this embodiment, the first target device 10 is the aforementioned base station, and the second target device 20 is the aforementioned cleaning device. The cleaning device can be a vacuum cleaner or a floor scrubber, etc. This embodiment does not specifically limit the type of cleaning device; it depends on the actual situation. When the first target device 10 and the second target device 20 are connected, the drain port of the cleaning device and the connection port 2 of the base station are connected.

[0063] Please refer to the specific details. Figures 3 to 6 Specifically, the locking device 4 includes a locking mechanism 41 and a magnetic adsorption mechanism 42. The locking mechanism 41 is adapted to be installed on the first target device 10 and is movable relative to the first target device 10. The magnetic adsorption mechanism 42 includes a first magnetic adsorption member 421 installed on and electrically connected to the first target device 10, and a second magnetic adsorption member 422 connected to the locking mechanism 41. The first magnetic adsorption member 421 and the second magnetic adsorption member 422 cooperate to lock or release the locking mechanism 41.

[0064] In some embodiments, the first target device 10 is also provided with a locking structure, which includes a drive motor and a hook connected to the drive motor. The drive motor drives the hook to move so that the hook locks or releases the first target device and the second target device. However, since the drive motor requires power, if an unexpected power outage occurs after the first target device 10 and the second target device 20 are connected and the corresponding operation is completed, the drive motor will be unable to operate, and the first target device 10 and the second target device 20 cannot be separated under the locking action of the hook, thereby affecting the use of the second target device 20 and the first target device 10.

[0065] To prevent the first target device 10 and the second target device 20 from being unable to separate during an unexpected power outage, thus affecting their use, in this embodiment, the first magnetic adsorption member 421 is an electromagnet, and the second magnetic adsorption member 422 is a magnetic metal. When the electromagnet is energized, it generates magnetism and can then attract the magnetic metal to lock the locking mechanism 41. At this time, the first target device 10 and the second target device 20 are locked under the action of the locking mechanism 41. When there is an unexpected power outage, the electromagnet is not energized and therefore does not have magnetism, so it cannot attract the magnetic metal. At this time, the locking mechanism 41 is not constrained by the magnetic force and is released. At this time, the first target device 10 and the second target device 20 are not affected by the locking mechanism 41, and the first target device 10 and / or the second target device 20 can move under the action of external force, thereby separating the first target device 10 and the second target device 20.

[0066] The magnetic metals mentioned above can be iron, cobalt, nickel, etc., and are not specifically limited here, depending on the actual situation.

[0067] At least a portion of the locking mechanism 41 protrudes from the first target device 10 so that when the second target device 20 is installed and connected to the first target device 10, at least a portion of the locking mechanism 41 can lock the first target device 10 and the second target device 20.

[0068] As can be seen from the foregoing, the first magnetic adsorption member 421 can be adsorbed with the second magnetic adsorption member 422 when energized, and can be separated from the second magnetic adsorption member 422 when not energized, so that the magnetic adsorption mechanism 42 has a locked state and an unlocked state.

[0069] Specifically, when the first target device 10 and the second target device 20 are installed and connected, the first magnetic adsorption component 421 is not powered on, so the first magnetic adsorption component 421 and the second magnetic adsorption component 422 are not adsorbed. The locking mechanism 41 protrudes from the first target device 10 and at least part of it moves under the squeezing action of the second target device 20, so as to drive the entire locking mechanism 41 and the second magnetic adsorption component 422 to move away from the first magnetic adsorption component 421, and the magnetic adsorption mechanism 42 is in the unlocked state. When the first target device 10 and the second target device 20 are installed in place, the force applied to the locking mechanism 41 disappears, the locking mechanism 41 resets to lock the first target device 10 and the second target device 20, the first target device 10 controls the first magnetic adsorption component 421 to be powered on, so that the first magnetic adsorption component 421 and the second magnetic adsorption component 422 are adsorbed and engaged, and the magnetic adsorption mechanism 42 is in the locked state.

[0070] The locking mechanism 41 includes a locking member and an elastic member 43 connecting the locking member and the first target device 10. The locking member is movable relative to the first target device 10, and the elastic member 43 is adapted to apply a force to the locking member so that at least a portion of the locking member protrudes from the first target device 10. This allows at least a portion of the locking member to connect the first target device 10 and the second target device 20 under the action of the elastic member 43 after the first target device 10 and the second target device 20 are installed and connected. In this embodiment, the elastic member 43 is a spring, which can be a compression spring, tension spring, etc., as long as it can deform under external force and return to its original shape when the external force is removed. This application does not specifically limit the type of elastic member 43; it depends on the actual situation.

[0071] In this embodiment, the first target device 10 is provided with a first slot 31, which is provided for at least part of the locking member to protrude from the first target device 10.

[0072] Accordingly, as described above, when the first target device 10 and the second target device 20 are installed and connected, at least some of the locking members can connect the first target device 10 and the second target device 20 under the action of the elastic member 43. Therefore, the second target device 20 is provided with a second slot corresponding to the first slot 31. When the first target device 10 and the second target device 20 are connected, the positions of the first slot 31 and the second slot are corresponding, and the first slot 31 and the second slot are connected, thereby allowing at least some of the locking members to pass through the first slot 31 and the second slot in sequence, thereby connecting the first target device 10 and the second target device 20.

[0073] The locking member has a locking portion 412, at least a portion of which protrudes from the first target device 10. In this embodiment, the locking portion 412 is located at the end of the locking member. When the locking member moves relative to the first target device 10, the locking portion 412 protrudes from the first target device 10 or moves into the first target device 10 as the locking member moves. The locking portion 412 is a protrusion extending outward from the end of the locking member. That is, in this embodiment, the locking portion 412 and the locking member are integrally formed to simplify the manufacturing process. In other embodiments, the locking portion 412 and the locking member can also be separately disposed and fixedly connected by means of bonding, welding, fastener connection, etc. No specific limitation is made here; it depends on the actual situation.

[0074] When the first target device 10 and the second target device 20 are connected, since at least a portion of the locking part 412 protrudes from the first slot 31 of the first target device 10, the locking member, under the squeezing action of the second target device 20, drives at least a portion of the locking part to move, causing the locking member to move toward the first target device 10. At this time, the elastic member 43 is squeezed and stores energy. After the first target device 10 and the second target device 20 are installed in place, the squeezing force applied to at least a portion of the locking part is removed, and the energy-stored elastic member 43 drives the locking member to reset as a whole, and then drives at least a portion of the locking member to move to the first slot 31 of the first target device 10, and protrudes from the first slot 31 to extend into the second slot, thereby connecting the first target device 10 and the second target device 20.

[0075] In one embodiment, the locking member is rotatably connected to the first target device 10 via a rotating shaft 44, allowing it to rotate relative to the first target device 10 and along the mounting directions of the first target device 10 and the second target device 20. In this embodiment, the mounting directions of the first target device 10 and the second target device 20 are parallel to the height direction of the first target device 10. The purpose of rotatably connecting the locking member to the first target device 10 via the rotating shaft 44 is that the locking member occupies a small volume within the first target device 10, and the first target device 10 and the second target device 20 can be locked by a small range of rotation of the locking member, thereby making the overall structure of the first target device 10 more compact.

[0076] Specifically, the locking component further includes a locking body 411, a connecting rod 413 rotatably connected at one end to the locking body 411, and a sliding block rotatably connected to the other end of the connecting rod 413. A locking part 412 is connected to the end of the locking body 411. The sliding direction of the sliding block is parallel to the installation direction of the first target device 10 and the second target device 20. A rotating shaft 44 is connected to the locking body 411. In this embodiment, the sliding block includes a main body and a connecting part connected to the main body, and the other end of the connecting rod 413 is rotatably connected to the connecting part.

[0077] In this embodiment, the second magnetic adsorption element 422 is disposed on the sliding block, and the elastic element 43 connects the sliding block and the first target device 10. In this embodiment, one end of the elastic element 43 is connected to the first target device 10, and the other end of the elastic element 43 is connected to the connecting part of the sliding block.

[0078] When the first target device 10 and the second target device 20 are installed, the second target device 20 squeezes at least part of the locking part 412 that protrudes from the first slot 31 of the first target device 10, so that the locking part 412 rotates away from the first slot 31, thereby driving the locking body 411 to rotate away from the first slot 31 as a whole, and driving the connecting rod 413 to rotate in the opposite direction to the installation direction, so that the sliding block moves in the opposite direction to the installation direction. While squeezing the elastic member 43 to store energy, the second magnetic adsorption member 422 and the second magnetic adsorption member 422 are separated.

[0079] After the first target device 10 and the second target device 20 are installed in place, the squeezing force applied by the second target device 20 to the locking part 412 that protrudes at least partially from the first slot 31 of the first target device 10 disappears, the external force received by the corresponding elastic member 43 disappears, and the elastic force returns to its original state, so that the sliding block drives the second magnetic adsorption member 422 to move toward the first magnetic adsorption member 421. The connecting rod 413 rotates under the movement of the sliding block, and then drives the locking body 411 to rotate toward the direction close to the first slot 31, until at least part of the locking part 412 protrudes from the first slot 31 to reset, so that at least part of the locking part 412 extends into the second slot, and then the first target device 10 and the second target device 20 are connected.

[0080] The locking part has a first guide surface 4121, which is adapted to guide the installation direction of the first target device 10 and the second target device 20. In this embodiment, the first guide surface 4121 is formed on the upper surface of the locking part, and in the installation direction of the first target device 10 and the second target device 20, the first guide surface 4121 is arranged from top to bottom toward the first magnetic adsorption member 421. By providing the first guide surface 4121, the first target device 10 and the second target device 20 can apply a pressing force to the locking part along the first guide surface 4121 during installation, thereby driving the locking part to rotate away from the first slot 31.

[0081] Similarly, to facilitate the disassembly of the first target device 10 and the second target device 20, the locking part also has a second guide surface 4122. The second guide surface 4122 is disposed opposite to the first guide surface 4121, and the setting direction of the second guide surface 4122 is opposite to that of the first guide surface 4121. "Relatively disposed" means that the second guide surface 4122 is formed on the lower surface of the locking part, and the upper and lower surfaces are disposed on the upper and lower sides of the locking part in the mounting direction of the first target device 10 and the second target device 20. By providing the second guide surface 4122, when the first target device 10 and the second target device 20 are disassembled, the second target device 20 can apply a pressing force to the locking part along the second guide surface 4122, thereby driving the locking part to rotate away from the first slot 31.

[0082] Meanwhile, the first target device 10 has a track that slides with the sliding block, and the track is distributed along the installation direction of the first target device 10 and the second target device 20 to make the sliding block slide stably.

[0083] In the above embodiment, the rotating shaft 44 is positioned near the middle of the locking body 411, one end of the connecting rod 413 is connected to the other end of the locking body 411, the first magnetic adsorption member 421 is positioned below the second magnetic adsorption member 422, and at this time, the elastic member 43 is positioned above the connecting rod 413.

[0084] Of course, in other embodiments, the rotating shaft 44 may also be located at the other end of the locking body 411, and one end of the connecting rod 413 may be connected to the middle position of the locking member. In this case, the first magnetic adsorption member 421 is located above the second magnetic adsorption member 422, and the elastic member 43 is located above the connecting rod 413.

[0085] In this embodiment, when the first target device 10 and the second target device 20 are installed, the second target device 20 squeezes at least partially the locking part 412 that protrudes from the first slot 31 of the first target device 10, so that the locking part 412 rotates in a direction away from the first slot 31, thereby driving the locking body 411 to rotate in a direction away from the first slot 31, and driving the connecting rod 413 to rotate in the same direction as the installation direction, so that the sliding block moves in the same direction as the installation direction. While squeezing the elastic member 43 to store energy, the second magnetic adsorption member 422 and the second magnetic adsorption member 422 are separated.

[0086] After the first target device 10 and the second target device 20 are installed in place, the squeezing force applied by the second target device 20 to the locking part 412 that protrudes at least partially from the first slot 31 of the first target device 10 disappears, the external force received by the corresponding elastic element 43 disappears, and the elastic force returns to its original state, so that the sliding block drives the second magnetic adsorption element 422 to move toward the first magnetic adsorption element 421. The connecting rod 413 rotates under the movement of the sliding block, and then drives the locking body 411 to rotate toward the direction close to the first slot 31, until at least part of the locking part 412 protrudes from the first slot 31 to reset, so that at least part of the locking part 412 extends into the second slot, and then the first target device 10 and the second target device 20 are installed and connected.

[0087] In another embodiment, the locking member is movable relative to the first target device 10, and the direction of movement of the locking member is perpendicular to the mounting direction of the first target device 10 and the second target device 20. That is, in this embodiment, the direction of movement of the locking member is horizontal. The elastic member 43 is connected to the locking member and the first target device 10 along the direction of movement, and the second magnetic adsorption member 422 is connected to the locking member.

[0088] When the first target device 10 and the second target device 20 are installed, at least part of the locking member protruding from the first target device 10 is squeezed by the second target device 20, causing the locking member to move away from the first slot 31. While squeezing the elastic member 43, the first magnetic adsorption member 421 and the second magnetic adsorption member 422 are separated.

[0089] When the first target device 10 and the second target device 20 are installed in place, the squeezing force applied to the locking member that protrudes at least partially from the first target device 10 disappears, and the elastic member 43 returns to its original state to drive the locking member to move toward the first slot 31 until at least part of the locking member protrudes from the first slot 31 again. At this time, the first magnetic adsorption member 421 and the second magnetic adsorption member 422 are connected.

[0090] Furthermore, in order to enable the locking member to move better, a slider 414 is provided on one of the locking members and the first target device 10, and a slide rail that slides and engages with the slider 414 is provided on the other of the locking members and the first target device 10.

[0091] In summary: This application incorporates a locking mechanism and a magnetic adsorption mechanism. The magnetic adsorption mechanism includes a first magnetic adsorption element electrically connected to the first target device and a second magnetic adsorption element connected to the locking mechanism and adsorbing with the first magnetic adsorption element. The locking mechanism is installed on the first target device and at least partially protrudes from it, so that after the second target device is installed on the first target device, the portion of the locking mechanism protruding from the first target device can connect the first and second target devices. When the first magnetic adsorption element is powered on, it engages with the second magnetic adsorption element to lock the locking mechanism, thereby enabling... The locking mechanism locks the first target device and the second target device. At this time, the second target device cannot be separated from the first target device under external force, thereby ensuring that the sewage discharge operation of the first and second target devices can be carried out normally and avoiding the possibility of dirt leakage. When the first magnetic adsorption component is not powered on, it can be separated from the second magnetic adsorption component to release the locking mechanism, thereby allowing the first and second target devices to be separated under external force. This ensures that the first and second target devices can still be separated in the event of an accidental power failure, without affecting the use of the first and / or second target devices, thus improving efficiency.

[0092] Example 2

[0093] Please see Figures 2 to 6 This embodiment provides a base station, including a base station body 1 and a locking device 4 disposed within the base station body 1. The locking device 4 protrudes at least partially from the base station body 1 and is adapted to lock the cleaning equipment to the base station body 1 when the cleaning equipment is installed. The locking device 4 is the same as the locking device 4 in Embodiment 1 described above. Accordingly, the base station body 1 serves as the first target device 10, and the cleaning equipment serves as the second target device 20.

[0094] To facilitate the installation of the base station body 1 and the cleaning equipment, the base station body 1 has a first mounting part 3, and the cleaning equipment has a second mounting part. The first mounting part 3 and the second mounting part are installed and cooperate with each other. Specifically, the first mounting part 3 is located on both sides of the connection port 2 of the base station body 1, and the second mounting part is located on both sides of the drain port of the cleaning equipment. After the cleaning equipment and the base station body 1 are installed and connected, the drain port and the connection port 2 are connected.

[0095] Furthermore, the first mounting part 3 is provided with a first slot 31, and the second mounting part is provided with a second slot. When the first mounting part 3 and the second mounting part are installed, the first slot 31 and the second slot correspond to each other. When the cleaning equipment is installed on the base station body 1, at least part of the locking device 4 passes through the first slot 31 and the second slot to lock the cleaning equipment and the base station body 1.

[0096] In this embodiment, one of the first mounting part 3 and the second mounting part is a plug-in post, and the other of the first mounting part 3 and the second mounting part is a plug-in groove that engages with the plug-in post.

[0097] Furthermore, a detection element is provided on the base station body 1, which is suitable for detecting the installation status of the cleaning equipment and the base station body 1; the first magnetic adsorption element 421 of the locking device 4 is energized to adsorb with the second magnetic adsorption element 422 of the locking device 4, or de-energized to detach from the second magnetic adsorption element 422, based on the detection result of the detection element.

[0098] In this embodiment, a detection element, which can be a pressure sensor, is provided on the base station body 1. When the pressure sensor is subjected to pressure applied by the cleaning equipment, it sends a signal to a controller located in the base station body 1. The controller receives the signal sent by the pressure sensor to control the first magnetic adsorption element 421 to be energized, thereby causing the first magnetic adsorption element 421 and the second magnetic adsorption element 422 to attract each other.

[0099] The detection element can also be a microswitch, which is electrically connected to the controller. When the cleaning equipment is installed on the base station body 1, the microswitch is triggered to send a signal to the controller. The controller controls the first magnetic adsorption element 421 to be energized, which in turn causes the first magnetic adsorption element 421 and the second magnetic adsorption element 422 to attract each other.
