[0062] An embodiment of the first aspect of this application provides a handheld cleaning device. Please refer to... Figures 1 to 3 The handheld cleaning device 100 includes a handle 10, a head 20, a body 30, an angle detection device 40, and a controller. The handle 10 is for the user to hold, the head 20 includes a first drive wheel 21 and a second drive wheel 22, and the body 30 connects the handle 10 and the head 20.

[0063] The angle detection device 40 includes a test piece 42 and a detection piece 41. The test piece 42 is mounted on the handle 10, and the detection piece 41 is mounted on the body 30. The handle 10 can rotate relative to the body 30 around the first axis X.

[0064] The controller is electrically connected to the angle detection device 40. The controller is used to obtain the rotation angle of the handle 10 relative to the body 30 based on the movement of the measured part 42 relative to the detection part 41. The controller is also electrically connected to the first drive wheel 21 and the second drive wheel 22 respectively. The controller is used to control the rotation speed of the first drive wheel 21 and the second drive wheel 22 respectively based on the rotation angle.

[0065] The handle 10 is for the user to hold, which can be understood as the user holding the handle 10 to operate the handheld cleaning device 100 to clean the floor. For example, the handle 10 is provided with knobs or buttons for functions such as start / stop, mode selection, and water volume adjustment.

[0066] The machine head 20 includes a first drive wheel 21 and a second drive wheel 22. That is, the machine head 20 moves automatically under the drive of the first drive wheel 21 and the second drive wheel 22 without the need for manual pushing by the user, which saves the user effort and improves the user experience. The machine body 30 is located between the first drive wheel 21 and the second drive wheel 22 in the extension direction of the rotation axis of the drive wheels.

[0067] The body 30 connects the handle 10 and the head 20, that is, the handle 10 is connected to the body 30, and the body 30 is connected to the head 20.

[0068] The test piece 42 is mounted on the handle 10, and the detection piece 41 is mounted on the body 30. The handle 10 can rotate relative to the body 30 around the first axis X. This can be understood as the test piece 42 moving relative to the detection piece 41 when the handle 10 rotates relative to the body 30 around the first axis X, thereby obtaining the rotation angle of the handle 10 relative to the body 30.

[0069] It is understandable that the controller can be located in the handle 10, the body 30, or the head 20.

[0070] The beneficial effects of the handheld cleaning device 100 provided in this application embodiment are as follows: The controller is electrically connected to the angle detection device 40 to obtain the rotation angle of the handle 10 relative to the body 30 based on the movement of the measured component 42 relative to the detection component 41; then, the controller can control the rotation speed of the first drive wheel 21 and the second drive wheel 22 respectively according to the rotation angle of the handle 10 relative to the body 30, so as to achieve steering through the difference in rotation speed of the first drive wheel 21 and the second drive wheel 22, and can control the size of the steering angle. Through the above design, the user can achieve steering of the handheld cleaning device 100 with less force, solving the problem that steering the handheld cleaning device 100 is relatively difficult.

[0071] Moreover, a small wrist rotation is all it takes to achieve a 100-degree turn of the handheld cleaning device, enhancing the user experience.

[0072] Please refer to Figure 3 and Figure 4In some embodiments, the handle 10 includes a handle body 11 and a rotating bracket 12. The rotating bracket 12 is rotatably mounted on the machine body 30 about a first axis X. The rotating bracket 12 is detachably connected to the handle body 11 and can rotate with the handle body 11 about the first axis X. The test piece 42 is disposed on the rotating bracket 12, and the detection piece 41 is disposed on the machine body 30.

[0073] The handle body 11 is connected to the body 30 via a rotating bracket 12. Since the rotating bracket 12 is rotatably mounted on the body 30 around the first axis X, and the rotating bracket 12 is detachably connected to the handle body 11, the handle body 11 can be removed from the body 30 to reduce the size of the handheld cleaning device 100 and facilitate its storage.

[0074] The rotating bracket 12 can rotate around the first axis X with the handle body 11. It can be understood that when the user rotates the handle body 11, the handle body 11 drives the rotating bracket 12 to rotate synchronously, so as to realize that the test piece 42 set on the rotating bracket 12 moves relative to the detection piece 41 set on the machine body 30, thereby obtaining the rotation angle of the handle 10 relative to the machine body 30.

[0075] Please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the rotating bracket 12 has a cylindrical structure, and one end of the handle body 11 is inserted into the rotating bracket 12. The outer wall of the handle body 11 is provided with an anti-rotation recess 111, and the inner wall of the rotating bracket 12 is provided with an anti-rotation protrusion 122 that cooperates with the anti-rotation recess 111.

[0076] For example, the rotating bracket 12 is a cylindrical structure. The first end of the rotating bracket 12 is an open structure for inserting the handle body 11; the second end of the rotating bracket 12 is provided with an electrical interface 126. After the handle body 11 is inserted into place, the end of the handle body 11 is connected to the electrical interface 126 so that the start / stop, mode selection, water volume adjustment and other functions of the handle 10 can be used normally.

[0077] For example, the anti-rotation recess 111 is a strip-shaped recess extending along the axial direction of the rotating bracket 12, and the anti-rotation protrusion 122 is a strip-shaped protrusion extending along the axial direction of the rotating bracket 12. When the handle body 11 is inserted into the rotating bracket 12, the anti-rotation protrusion 122 enters the anti-rotation recess 111, so that the handle body 11 and the rotating bracket 12 cannot rotate relative to each other in the circumferential direction of the rotating bracket 12, that is, the handle body 11 can drive the rotating bracket 12 to rotate together.

[0078] The axial direction of the rotating support 12 is the extension direction of the first axis X.

[0079] It can be understood that there can be one anti-rotation recess 111 and one corresponding anti-rotation protrusion 122; or, there can be multiple anti-rotation recesses 111 and multiple corresponding anti-rotation protrusions 122. When there are multiple anti-rotation recesses 111 and multiple anti-rotation protrusions 122, the multiple anti-rotation recesses 111 are arranged at intervals along the circumference of the handle body 11, and the multiple anti-rotation protrusions 122 are arranged at intervals along the circumference of the rotating bracket 12.

[0080] In other embodiments, the anti-rotation recess 111 can be provided on the inner wall surface of the rotating bracket 12, and the anti-rotation protrusion 122 can be provided on the outer wall surface of the handle body 11.

[0081] Please refer to Figure 4 and Figure 6 In some embodiments, the handle body 11 is provided with a locking tongue 112 and a locking elastic member 113, and the rotating bracket 12 is provided with a locking hole 125. The locking elastic member 113 is used to drive the locking tongue 112 to insert into the locking hole 125 when the locking tongue 112 is aligned with the locking hole 125.

[0082] For example, the locking elastic element 113 is a compression spring.

[0083] The latch 112 has a guide slope. When the handle body 11 is inserted into the rotating bracket 12, the guide slope of the latch 112 abuts against the end of the rotating bracket 12, causing the latch 112 to move inward into the handle body 11 and compress the locking elastic element 113. After the handle body 11 is fully inserted, the latch 112 aligns with the lock hole 125, and under the elastic force of the locking elastic element 113, the latch 112 is inserted into the lock hole 125, so that the handle body 11 and the rotating bracket 12 form a whole. When it is necessary to separate the handle body 11 from the rotating bracket 12, simply press the latch 112 and pull the handle body 11 along its axial direction.

[0084] For example, when the anti-rotation recess 111 is provided on the handle body 11, the locking tongue 112 and the anti-rotation recess 111 are respectively located on opposite sides of the handle body 11 in the radial direction of the handle body 11.

[0085] Based on the above solution, the connection and separation of the handle body 11 and the rotating bracket 12 are relatively simple and convenient.

[0086] Please refer to Figure 9 In some embodiments, the body 30 is provided with an annular groove 31, and the outer wall surface of the rotating bracket 12 is provided with a limiting protrusion 123. The annular groove 31 extends circumferentially along the rotating bracket 12, and the limiting protrusion 123 is located in the annular groove 31 and slides in the annular groove 31.

[0087] It is understandable that the cross-sectional shape of the annular groove 31 can be rectangular, trapezoidal, semi-circular, etc.

[0088] It is understood that the limiting protrusion 123 can be an annular protrusion or a C-shaped protrusion; or, the limiting protrusion 123 can include a plurality of limiting protrusions arranged at intervals along the circumference of the rotating bracket 12.

[0089] It is understood that one annular groove 31 can be provided, and correspondingly, one limiting protrusion 123 can be provided; or, multiple annular grooves 31 can be provided, and correspondingly, multiple limiting protrusions 123 can be provided. When multiple annular grooves 31 and multiple limiting protrusions 123 are provided, the multiple annular grooves 31 are arranged at intervals along the axial direction of the rotating bracket 12, and the multiple limiting protrusions 123 are arranged at intervals along the axial direction of the rotating bracket 12.

[0090] The limiting protrusion 123 is located in the annular groove 31 and slides in the annular groove 31, so that the rotating bracket 12 is rotatably mounted on the machine body 30, and the rotating bracket 12 cannot move relative to the machine body 30 in the axial direction of the rotating bracket 12.

[0091] In other embodiments, the annular groove 31 may be provided on the outer wall surface of the rotating bracket 12, and the limiting protrusion 123 may be provided on the body 30.

[0092] Please refer to Figure 10 and Figure 11 In some embodiments, a reset elastic element 50 is provided between the body 30 and the rotating bracket 12. When the force of the drive handle body 11 disappears, the reset elastic element 50 restores the rotating bracket 12 to its original position.

[0093] For example, the rotating bracket 12 is provided with a first frame 124, and the body 30 is provided with a second frame 32. The first end of the reset elastic member 50 is connected to the first frame 124, and the second end of the reset elastic member 50 is connected to the second frame 32. The first frame 124 and the second frame 32 are both located on the outside of the rotating bracket 12.

[0094] For example, the reset elastic element 50 is a tension spring.

[0095] For example, in its natural state, handle 10 is in the center position.

[0096] Based on the above technical solution, after the handheld cleaning device 100 has finished cleaning the floor, the user releases the handle 10, and the handle 10 automatically returns to its original position under the elastic force of the reset elastic member 50, so that the handheld cleaning device 100 can be used again next time.

[0097] In other embodiments, instead of providing a reset elastic element 50 between the body 30 and the rotating bracket 12, the handle 10 can be manually returned to its original position.

[0098] Please refer to Figure 11 In some embodiments, the reset elastic element 50 includes a first elastic element 51 and a second elastic element 52, which are located on both sides of the rotating bracket 12 in the radial direction.

[0099] For example, both the first elastic element 51 and the second elastic element 52 are tension springs.

[0100] Based on the above technical solution, it can be ensured that the rotating bracket 12 is subjected to uniform force, which is conducive to the rotating bracket 12 returning to its original position.

[0101] Please refer to Figure 3 In some embodiments, the test element 42 is a probe, the detection element 41 is a resistor, the probe contacts the resistor and can slide relative to the resistor; the controller is used to obtain the rotation angle of the handle 10 relative to the body 30 based on the change in the resistance value of the resistor.

[0102] For example, the rotating bracket 12 is provided with a mounting part 121, and the probe is fixed to the mounting part 121 by means of bonding, pressing, interference fit, snap-fit, fastener connection, etc.

[0103] For example, the resistor is fixed to the body 30 by means of bonding, pressing, interference fit, snap-fit, fastener connection, etc.

[0104] The probe is connected to the controller via a first wire, and the resistor is provided with a connecting post 411, which is connected to the controller via a second wire.

[0105] As the rotating bracket 12 rotates relative to the body 30, the probe slides relative to the resistor. By moving the probe closer to or further away from the connecting post 411, the resistance is changed, thereby controlling the direction of rotation via the controller. For example, the resistor has an arc-shaped structure.

[0106] For example, the probe and the connecting post 411 are at a set distance. At this set distance, the resistance of the resistor is constant, and the rotation speed of the second drive wheel 22 is equal to the rotation speed of the first drive wheel 21. When the handle 10 is turned to the left, the probe moves closer to the connecting post 411, making the distance between the probe and the connecting post 411 less than the set distance. The resistance of the resistor decreases, and the controller receives the signal of the decreased resistance and controls the rotation speed of the second drive wheel 22 to be less than the rotation speed of the first drive wheel 21, so that the handheld cleaning device 100 turns to the left. The smaller the resistance of the resistor, the larger the angle of turning to the left. When the handle 10 is turned to the right, the probe moves away from the connecting post 411, making the distance between the probe and the connecting post 411 greater than the set distance. The resistance of the resistor increases, and the controller receives the signal of the increased resistance and controls the rotation speed of the second drive wheel 22 to be greater than the rotation speed of the first drive wheel 21, so that the handheld cleaning device 100 turns to the right. The larger the resistance of the resistor, the larger the angle of turning to the right.

[0107] In some embodiments, the test element 42 is a magnetic element, the detection element 41 is a Hall sensor, and the controller is used to obtain the rotation angle of the handle 10 relative to the body 30 based on the change in the magnetic field sensed by the Hall sensor.

[0108] In some embodiments, the test element 42 is a grating, the detection element 41 is a photodetector, and the controller is used to obtain the rotation angle of the handle 10 relative to the body 30 based on the light passing through the grating detected by the photodetector.

[0109] In other embodiments, the rotation angle of the handle 10 relative to the body 30 can also be obtained by means of an optocoupler (photoelectric encoder), gyroscope, pressure gauge, etc.

[0110] Please refer to Figure 12 The test piece 42 is mounted on the machine body 30, and the detection piece 41 is mounted on the machine head 20. The machine body 30 can rotate relative to the machine head 20 around the second axis Y.

[0111] For example, the test piece 42 is a probe, the detection piece 41 is a resistor, the probe contacts the resistor and can slide relative to the resistor, and the controller is used to obtain the rotation angle of the body 30 relative to the head 20 based on the change in the resistance value of the resistor.

[0112] For example, the test component 42 is a magnetic component, the detection component 41 is a Hall sensor, and the controller is used to obtain the rotation angle of the body 30 relative to the head 20 based on the change in the magnetic field sensed by the Hall sensor.

[0113] For example, in some embodiments, the test element 42 is a grating, the detection element 41 is a photodetector, and the controller is used to obtain the rotation angle of the body 30 relative to the head 20 based on the light passing through the grating detected by the photodetector.

[0114] For example, the rotation angle of the body 30 relative to the head 20 can also be obtained by using an optocoupler (photoelectric encoder), gyroscope, pressure gauge, etc.

[0115] The second aspect of this application provides a cleaning system comprising a charging dock and a handheld cleaning device 100 as described in the first aspect, the charging dock being used to charge the handheld cleaning device 100.

[0116] The cleaning system employs any one or more embodiments of the handheld cleaning device 100 described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.
