Description

Technical Field

[0001] This utility model relates to the field of cleaning robots, specifically to a cleaning component and robot. Background Technology

[0002] Currently, due to limitations in the sealed structure of water jet spray discs, it is impossible to directly obtain the rotational speed of the internal spray bar, lacking an effective measurement method. When the spray bar becomes stuck, the water jet cannot form a sweeping trajectory on the work surface, but instead continuously impacts a fixed area, which may damage the work surface over time. If the spray bar rotational speed is too low, the cleaning coverage will decrease, reducing work efficiency; while if the speed is too high, the water jet impact force will be insufficient, resulting in poor cleaning effect and difficulty in effectively removing paint and rust.

[0004] Furthermore, the water jet has a first flow channel and a second flow channel; The first flow channel and the second flow channel are spaced apart within the water jet along a first direction, and the water outlets are spaced apart on the surface of the water jet, with the water outlets communicating with the first flow channel and the second flow channel.

[0005] Furthermore, the water jet also includes: a water inlet pipe; The water inlet pipe is fixedly connected to the water jet, and the water inlet pipe is provided with a water inlet channel, which is connected to the first channel and the second channel.

[0006] Furthermore, it also includes: a recycling port; The recovery port is located on the cleaning tray, and the recovery port is connected to a recovery pipe. The recovery pipe is connected to a negative pressure pump, which is used to generate negative pressure in the cleaning tray to recover the water flow.

[0007] Furthermore, it also includes: magnetic components; The magnetic component is disposed at one end or both ends of the water jet, and the magnetic component is used to cooperate with the detection component.

[0008] Furthermore, the detection element is an optical detection element or an eddy current detection element.

The rotational torque generated during the spraying process drives the water jet to rotate. The larger the water flow, the faster the rotation, resulting in a better cleaning effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0019] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Please see Figure 1 A cleaning assembly 100 includes: a cleaning disc 10, a water jet 20, and a detection element 30; The water jet 20 is rotatably disposed within the cleaning disc 10, and the water jet 20 is provided with multiple water outlets 23; the cleaning disc 10 is fixedly provided with at least one detection element 30, which is used to detect the rotational speed of the water jet 20.

[0021] The cleaning assembly includes a cleaning disc 10, which is a ring-shaped metal disc with a water jet 20 installed inside. The water jet 20 has fluid channels and water outlets on its surface. The water jet 20 is rotatably mounted on the cleaning disc 10. When high-pressure water enters the water jet 20, it is sprayed out through multiple outlets 23 distributed on its surface, forming a highly concentrated water jet. These high-speed water jets have a strong impact force, which can effectively remove rust, paint, and dirt from the working surface. The rotational torque generated by these water jets during the spraying process drives the water jet 20 to rotate. The larger the water jet, the faster it rotates, resulting in a better cleaning effect. Therefore, a detection element 30 is set on the cleaning disc 10 to detect the rotational speed of the water jet 20. The rotational speed obtained by the detection element 30 is used to judge the current cleaning effect of the surface, thereby improving the controllability and intelligence of the operation process, timely detecting spray bar jamming or abnormal rotational speed, and avoiding damage to the working surface.

[0022] In some implementations, the cleaning assembly also includes a control system that can adjust drive parameters or issue an alarm in a timely manner when the rotational speed is detected to be lower than a set threshold, so as to ensure that the cleaning operation is always kept in the best working condition.

[0023] Please see Figure 2 In some embodiments, the water jet 20 has a first flow channel 21 and a second flow channel 22; The first flow channel 21 and the second flow channel 22 are spaced apart within the water jet 20 along a first direction, and the water outlet 23 is spaced apart on the surface of the water jet 20, and the water outlet 23 communicates with the first flow channel 21 and the second flow channel 22.

[0024] Understandably, the water jet 20 has a first flow channel 21 and a second flow channel 22 inside. The first flow channel 21 and the second flow channel 22 are spaced apart inside the water jet 20 along a first direction, that is, the first flow channel 21 and the second flow channel 22 are arranged parallel inside the water jet 20. At least two sets of water outlets 23 are also spaced apart on the surface of the water jet 20. Both sets of water outlets 23 are spaced apart along the first direction. One set is connected to the first flow channel 21, and the other set is connected to the second flow channel 22. The first flow channel 21 and the second flow channel 22 are used to supply water to the water outlets 23. In this way, water can be supplied to the two sets of water outlets 23 through the first flow channel 21 and the second flow channel 22 respectively. When the water jet 20 rotates, the sets of water outlets 23 of the first flow channel 21 and the second flow channel 22 alternately contact the working surface, forming a dynamically superimposed cleaning trajectory to reduce cleaning blind spots.

[0025] Please see Figure 2 In some embodiments, the water jet 20 further includes: a water inlet pipe 40; The water inlet pipe 40 is fixedly connected to the water jet 20, and the water inlet pipe 40 is provided with a water inlet channel, which is connected to the first channel 21 and the second channel 22.

[0026] Understandably, the water inlet pipe 40 is fixedly connected to the water jet 20, and the water inlet pipe 40 is provided with a water inlet channel. The water inlet channel is a channel structure set inside the water inlet pipe 40, which can be realized by opening a through hole inside the pipe body, for introducing external water source into the water jet 20. The water flows through the water inlet channel and simultaneously enters the first channel 21 and the second channel 22, and then forms multiple jets through the water outlet 23, forming a cleaning area in the cleaning plate 10 to achieve cleaning.

[0027] Please see Figure 3 In some implementations, it also includes: a recycling port 50; The recovery port 50 is provided on the cleaning tray 10. The recovery port 50 is connected to a recovery pipe, and the recovery pipe is connected to a negative pressure pump. The negative pressure pump is used to generate negative pressure in the cleaning tray 10 to recover the water flow.

[0028] Understandably, a recycling port 50 is also provided on the cleaning tray 10. The recycling port 50 is connected to a recycling pipe, which is connected to a negative pressure pump. When the cleaning tray 10 comes into contact with the wall or surface, it can create a relatively sealed space inside the cleaning tray 10. When the negative pressure pump is working, negative pressure can be generated inside the cleaning tray 10, so the water can be recycled through the recycling pipe. After the water is filtered, it can be reused, which can reduce water waste and reduce the impact on the surrounding environment during the cleaning process, thereby improving the user experience.

[0029] In some embodiments, it also includes: a braking element; The braking component is located on the side of the cleaning disc 10 away from the water jet 20, and the braking component is connected to the water inlet pipe 40. The braking component is used to brake the water jet 20.

[0030] Understandably, the brake is located on the side of the cleaning disc 10 away from the water jet 20, and the brake is connected to the water inlet pipe 40. The rotational torque generated by the water flow during the spraying process drives the water jet 20 to rotate. In order to adjust or enable the water jet 20 to stop quickly, a brake is installed on the water inlet pipe 40. The rotation of the water inlet pipe 40 can be adjusted by the brake, thereby limiting the rotation of the water jet 20. In this way, the rotation speed of the water jet 20 can be adjusted, so that the water jet 20 can stop rotating quickly after cleaning is completed.

[0031] In some embodiments, it also includes: a magnetic element; The magnetic component is disposed at one end or both ends of the water jet 20, and the magnetic component is used to cooperate with the detection component 30.

[0032] Understandably, this also includes: magnetic components, which are fixedly installed at one end of the water jet 20 or at both ends of the water jet 20. The magnetic components are elements that can generate a magnetic field. Specifically, permanent magnets can be used to generate identifiable signals by cooperating with the magnetic field of the detection element 30.

[0033] Specifically, the detection element 30 can be set as a Hall sensor. When the water jet 20 rotates, the magnetic component periodically passes through the detection element 30. The detection element 30 generates a pulse signal by sensing the periodic change in the magnetic field strength. The pulse frequency is proportional to the rotation speed of the water jet 20, thereby realizing non-contact detection of the rotation speed. When the detection element 30 detects an abnormal rotation speed, such as jamming causing a sudden drop in rotation speed or drive overload causing rotation speed fluctuations, the cleaning component can be stopped, thereby avoiding the problem of reduced cleaning effect or damage to the working surface caused by uncontrolled rotation speed.

[0034] In some embodiments, the detection element 30 is an optical detection element 30 or an eddy current detection element 30.

[0035] Understandably, the optical detection element 30 refers to a device that uses optical principles to detect the motion of an object. Specifically, it can be implemented using a photoelectric encoder or a laser reflection sensor. It converts changes in the light signal reflected or blocked by the magnetic element into rotation speed information. In particular, when the magnetic element rotates with the water jet 20, the optical detection element 30 emits a light beam and receives the light pulse signal formed by the reflection or blocking of the magnetic element, and determines the rotation speed based on the pulse frequency. The eddy current detection element 30 generates a high-frequency electromagnetic field through a coil. When the detection element 30 approaches the sensor, eddy currents are induced on its surface. These eddy currents, in turn, affect the electromagnetic field of the sensor, causing a change in the voltage or frequency signal output by the sensor. The rotational speed can be calculated by counting the number of signal cycles per unit time.

[0036] Please see Figure 4 The present invention also provides a robot 200, including: a body 210, and the cleaning component 100; The cleaning component is fixedly connected to the body 210, and the body 210 is used to drive the cleaning component to move.

[0037] Understandably, the main body 210 refers to the main structure of the robot 200. The cleaning component 100 is fixedly mounted on the main body 210. The robot 200 can drive the cleaning component 100 to move, thereby achieving the purpose of cleaning the wall. During the movement of the robot 200, the water jet 20 rotates and sprays water within the cleaning disc 10. The rotation speed of the water jet 20 is detected by the detection element 30. When an abnormal rotation speed of the water jet 20 is detected, the main body 210 can immediately stop moving to prevent the high-pressure water jet from continuously impacting the fixed position. When the rotation speed returns to normal, the main body 210 automatically resumes movement, ensuring a balance between cleaning efficiency and cleaning effect.

[0038] Please see Figure 5 In some embodiments, the body 210 includes: Frame size 220; A drive mechanism 230 is provided on both sides of the frame 220. The drive mechanism 230 is movable on the frame 220 and is used to drive the frame 220 to move. The adaptive adjustment component 240 includes: a support 241 and a moving mechanism 242. The support 241 is movably connected to the frame 220, and the moving mechanism 242 is connected to the support 241. The support 241 is rotatable so that the moving mechanism 242 contacts the plane.

[0039] Understandably, the robot 200 includes a frame 220, with drive mechanisms 230 on both sides of the frame 220. The drive mechanisms 230 can drive the frame 220 to move. When the robot 200 climbs a curved surface, the drive mechanisms 230 on both sides of the frame 220 can move within a certain range, allowing the drive mechanisms 230 to have a larger contact area with the curved surface (e.g., a column), thereby improving the stability of the robot 200. An adaptive adjustment component 240 is also provided at the front of the frame 220. The adaptive adjustment component 240 includes a support 241 and a moving mechanism 242. The support 241 is connected to the frame 220 and is movably connected to the moving mechanism 242. When the moving mechanism 242 is on a curved surface, the support 241 can adjust the contact between the moving mechanism 242 and the curved surface to increase the contact area between the moving mechanism 242 and the curved surface, avoiding the loss of driving force due to partial disengagement, thereby improving the climbing effect of the robot 200.

[0040] Please see Figure 6 In some embodiments, the drive mechanism 230 includes: a connecting frame 231, a first drive wheel 232, and a second drive wheel 233; The connecting frame 231 is rotatably connected to the frame 220. The first drive wheel 232 and the second drive wheel 233 are spaced apart on the connecting frame 231. The first drive wheel 232 and the second drive wheel 233 are used to drive the robot 200 to move.

[0041] Understandably, a first drive wheel 232 and a second drive wheel 233 are respectively provided on both sides of the connection. The connecting frame 231 can be equipped with a power unit connected to the first drive wheel 232 and the second drive wheel 233, thus driving the frame 220 to move. The connecting piece is rotatably connected to the frame 220. When the robot 200 comes into contact with an inclined or uneven wall surface, the connecting frame 231 can deflect around the axis of the frame 220 at a certain angle. At this time, the first drive wheel 232 and the second drive wheel 233 continuously output power under the drive of independent motors. Since the dual drive wheels are arranged alternately on the connecting frame 231, when the connecting frame 231 deflects, the overall contact angle of the drive wheel assembly changes accordingly, ensuring that at least one drive wheel always maintains effective contact with the wall surface. This achieves the purpose of improving the stability of the robot 200.

[0042] Please see Figure 7 In some embodiments, the moving mechanism 242 includes: a first moving wheel 243 and a second moving wheel 244; The first movable wheel 243 and the second movable wheel 244 are spaced apart on the bracket 241, and the first movable wheel 243 and the second movable wheel 244 can rotate around the bracket 241.

[0043] Understandably, the first moving wheel 243 and the second moving wheel 244 are used to contact the wall surface and increase the friction between the robot 200 and the wall surface. To improve the friction of the first moving wheel 243 and the second moving wheel 244, textures can be provided on their surfaces. The first moving wheel 243 and the second moving wheel 244 are spaced apart on the support 241, and the first moving wheel 243 and the second moving wheel 244 can rotate on the support 241, thus enabling the first moving wheel 243 and the second moving wheel 244 to adjust their direction. Specifically, when the robot 200 moves to a curved or inclined surface, the support 241 rotates so that the first moving wheel 243 and the second moving wheel 244 are in contact with the contact surface. Because the two moving wheels are spaced apart, when encountering a raised or recessed area, one wheel can be raised or lowered while the other wheel remains in contact, thereby preventing the entire robot from detaching from the surface. This enhances the stability and obstacle-crossing ability of the robot 200 when moving on complex surfaces.
