Description

Technical Field

[0001] The present application relates to the technical field of knobs, and in particular to a knob, a control element and a toilet. Background Art

[0002] With the rapid development of smart toilets, smart toilets are usually equipped with knobs that can be rotated to different gears to realize the switching or control of some functions in the smart toilet, such as the switching of the seat heating function and the control of the temperature, or the switching of the spray function and the spray intensity, etc. However, the feedback of the gear change when the knob is rotated is not obvious. It is difficult for the user to perceive the rotation stroke when rotating the knob, and thus it is difficult to perceive the gear change. The user needs to observe the mark on the knob to obtain the gear change. Summary of the invention

[0003] Based on this, it is necessary to provide a knob, a control element and a toilet to address the problem that it is difficult for users to perceive the rotation stroke and thus the change of gear position when rotating the knob.

[0009] In the process of rotating the knob, that is, driving the rotating structure to rotate relative to the main body along the circumference of the main body, any magnetic element is opposite to different magnetic parts in turn, and any magnetic part is opposite to different magnetic elements in turn. Since the direction of the magnetic interaction force between any of the magnetic elements and any two adjacent magnetic parts is opposite, or the direction of the magnetic interaction force between any of the magnetic parts and any two adjacent magnetic elements is opposite, the alternating change of the direction of the magnetic interaction force between the magnetic elements and the magnetic parts during rotation will cause the interaction force between the rotating part and the main body to change alternately, thereby producing an obvious alternating change in hand feel. When the arrangement of the magnetic elements and the magnetic parts corresponds to the gear change of the knob, the number of gear changes can be clearly perceived through the number of changes in hand feel during the rotation process, so that the rotation stroke and gear change of the knob can be clearly perceived without observing the displacement of the mark on the knob, which is conducive to precise control of the rotation gear.

The plurality of accommodating grooves are arranged in sequence and spaced apart along the circumference of the main body, and the plurality of magnetic elements are arranged in the accommodating grooves in a one-to-one correspondence.

[0013] In one embodiment, the knob also includes a cover body, which is connected to the main body and arranged around the first circuit board. The cover body includes a main body portion and a connecting portion that are connected to each other. A groove body arranged around the first circuit board is opened on one side of the main body facing the cover body, and the connecting portion is inserted into the groove body.

[0015] In one embodiment, an annular groove opposite to the main body is formed on the inner surface of the rotating structure, the annular groove is located on a side of the limiting portion facing away from the main body, and the magnetic matching member is accommodated in the annular groove;

[0016] And / or, the knob further includes a display screen, which is disposed on the main body and shields the first circuit board, and the display screen is electrically connected to the circuit board.

[0035] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the structure of the control element 10 in some embodiments, Figure 2 for Figure 1 The exploded schematic diagram of the control element 10 is shown, Figure 3Schematic cross-sectional view of the knob 20 in some embodiments. The control element 10 provided in the present application can realize the key sensing function and the rotation sensing function. In some embodiments, the control element 10 includes a knob 20 and a button seat 11. The knob 20 is arranged on the button seat 11 and can reciprocate relative to the button seat 11 in the axial direction. When the user presses the knob 20 to drive the knob 20 to move in a direction close to the button seat 11 relative to the button seat 11, the control element 10 can sense the user's pressing action, thereby realizing the key sensing function. After the key sensing is completed, the user releases the knob 20, and the knob 20 can be reset by moving in a direction away from the button seat 11 relative to the button seat 11 with the help of elastic elements such as springs. In some embodiments, the knob 20 includes a main body 21 and a rotating structure 22, and the rotating structure 22 is arranged around the main body 21 and can rotate relative to the main body 21 in the circumferential direction of the main body 21. When the user rotates the rotating structure 22 to drive the rotating structure 22 to rotate relative to the main body 21, the control element 10 can sense the user's rotation operation, thereby realizing the rotation sensing function.

[0036] The control element 10 provided in the present application can be used for any applicable function such as a toilet that requires the rotation sensing function of the knob 20 and / or the key sensing function of the button to realize the switch, adjustment or switching of the function. For example, when the control element 10 is used for a toilet, the key sensing function of the control element 10 can be used to realize the switch control of any applicable function such as the switch of the flushing function of the toilet, the switch of the spray function, the switch of the seat heating function, the switch of the indicator light or the lighting lamp. The rotation sensing function of the control element 10 can be used to realize the adjustment or switching of any applicable function such as the water type and intensity of the spray function, the temperature of the seat heating function, the switching of multiple intelligent functions. Of course, the application scenario of the control element 10 and the type of corresponding function control are not limited to this. As long as the key sensing function or rotation sensing function of the control element 10 can be used to realize a specific function, it is not limited in the present application.

[0037] Furthermore, combined with Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the knob 20 includes a magnetic matching piece 23 and a plurality of magnetic elements 24. The magnetic matching piece 23 is provided on the rotating structure 22 and is arranged around the main body 21. The magnetic matching piece 23 has a plurality of magnetic parts 231 arranged in sequence in the circumferential direction of the main body 21. The plurality of magnetic elements 24 are provided on the main body 21 and are arranged in sequence in the circumferential direction of the main body 21. When the rotating structure 22 rotates relative to the main body 21 along the circumferential direction of the main body 21, any magnetic element 24 will be opposite to the plurality of magnetic parts 231 in sequence, and any magnetic part 231 will be opposite to the plurality of magnetic elements 24 in sequence. A magnetic interaction force will be generated between the magnetic elements 24 and the magnetic parts 231 that are opposite in the radial direction of the main body 21, such as a magnetic attraction force or a magnetic repulsion force. The magnetic element 24 includes but is not limited to any applicable element capable of generating a magnetic field, such as a magnet or a magnet, and the magnetic part 231 is a part on the magnetic matching piece 23 that can generate a magnetic field.

[0038] In some embodiments, the magnetic interaction force between any magnetic element 24 and any two adjacent magnetic parts 231 is opposite. In other words, during the rotation of the rotating structure 22 relative to the main body 21 along the circumferential direction, when any magnetic element 24 is opposite to different magnetic parts 231 in turn, the magnetic interaction force between the magnetic element 24 and the different magnetic parts 231 in turn switches between magnetic attraction and magnetic repulsion. In other embodiments, the direction of the magnetic interaction force between any magnetic part 231 and any two adjacent magnetic elements 24 is opposite. In other words, during the rotation of the rotating structure 22 relative to the main body 21 along the circumferential direction, when any magnetic part 231 is opposite to different magnetic elements 24 in turn, the magnetic interaction force between the magnetic part 231 and the different magnetic elements 24 in turn switches between magnetic attraction and magnetic repulsion.

[0039] In the process of rotating the knob 20, i.e., driving the rotating structure 22 to rotate relative to the main body 21 along the circumference of the main body 21, any magnetic element 24 is opposite to different magnetic parts 231 in sequence, and any magnetic part 231 is opposite to different magnetic elements 24 in sequence. Since the directions of the magnetic interaction forces between any magnetic element 24 and any two adjacent magnetic parts 231 are opposite, or the directions of the magnetic interaction forces between any magnetic part 231 and any two adjacent magnetic elements 24 are opposite, the directions of the magnetic interaction forces between the magnetic element 24 and the magnetic parts 231 will change alternately during the rotation process, for example, alternating between magnetic attraction and magnetic repulsion, which will cause the interaction force between the rotating part 221 and the main body 21 to change alternately, thereby generating an obvious alternating hand feeling, wherein the number of hand feeling changes corresponds to the number of magnetic parts 231 that the magnetic element 24 passes sequentially, or the number of magnetic elements 24 that the magnetic parts 231 pass sequentially. When the number and arrangement of the magnetic elements 24 and the magnetic parts 231 correspond to the gear changes of the knob 20, the number of gear changes can be clearly perceived by the number of changes in the hand feel during the rotation process, so that the rotation stroke and gear changes of the knob 20 can be clearly perceived without observing the displacement of the mark on the knob 20, which is conducive to precise control of the rotation gear.

[0040] For example, when the circumferential distance between two adjacent magnetic parts 231 corresponds to a gear change, when the rotating structure 22 rotates relative to the main body 21 until the magnetic part 231 is opposite to two different magnetic elements 24 in turn, the feel of the knob 20 changes twice, and the user can clearly feel that the gear has been adjusted by two levels.

[0041] In some embodiments, the magnetic poles of the plurality of magnetic elements 24 in the radially outward direction of the main body 21 are oriented in the same direction, and the magnetic poles of any two adjacent magnetic parts 231 in the radially outward direction of the main body 21 are oriented in opposite directions, so as to achieve the effect that the magnetic interaction forces between any of the magnetic elements 24 and any two adjacent magnetic parts 231 are oriented in opposite directions. For example, the south poles of the plurality of magnetic elements 24 are all oriented toward the outside of the main body 21, that is, toward the rotating structure 22, or the north poles of the plurality of magnetic elements 24 are all oriented toward the outside of the main body 21, while the south poles of any two adjacent magnetic parts 231 are oriented in opposite directions, with the south pole of one magnetic part 231 facing the main body 21 and the south pole of the other magnetic part 231 facing away from the main body 21.

[0042] In other embodiments, the magnetic poles of any two adjacent magnetic elements 24 in the radial outward direction of the main body 21 are oriented in opposite directions, and the magnetic poles of the plurality of magnetic parts 231 in the radial outward direction of the main body 21 are oriented in the same direction, so as to achieve the effect that the magnetic interaction force between any magnetic part 231 and any two adjacent magnetic elements 24 is in opposite directions. For example, the south poles of the plurality of magnetic parts 231 are all oriented toward the main body 21, or are all facing away from the main body 21, while the south poles of any two adjacent magnetic elements 24 are oriented in opposite directions, with the south pole of one magnetic element 24 facing the main body 21 and the south pole of the other magnetic element 24 facing away from the main body 21. The arrangement of the magnetic poles of the magnetic elements 24 is not limited thereto, as long as it can be achieved that during the rotation of the rotating structure 22 relative to the main body 21, the magnetic interaction force between the magnetic elements 24 and the magnetic parts 231 alternates between magnetic attraction and magnetic repulsion.

[0043] In some embodiments, the direction in which the south pole of the magnetic element 24 points to the north pole is parallel to the radial direction of the main body 21, and the direction in which the south pole of the magnetic part 231 points to the north pole is parallel to the radial direction of the main body 21. Therefore, when the magnetic element 24 and the magnetic part 231 are opposite to each other, the magnetic element 24 and the magnetic part 231 can generate a strong magnetic interaction force, effectively improving the change of the interaction force between the rotating structure 22 and the main body 21 during the rotation process, thereby generating a change in the feel that is more easily perceived by the user.

[0044] Please see again Figure 1 , Figure 2 and Figure 3 In some embodiments, the knob 20 further includes a first circuit board 25, a cover 26, and a display screen 27. The first circuit board 25 is disposed on the main body 21. The cover 26 is connected to the main body 21 and is disposed around the first circuit board 25 to provide protection for the first circuit board 25. The display screen 27 includes but is not limited to any applicable display device such as a liquid crystal screen. The display screen 27 is disposed on the cover 26 and shields the first circuit board 25, so as to prevent the first circuit board 25 from being exposed.

[0045] The display screen 27 is provided to display the function or status information corresponding to the rotation, enriching the function and use experience of the control element 10. The first circuit board 25 includes but is not limited to a printed circuit board. The first circuit board 25 can be electrically connected to the display screen 27 to realize the control of the display screen 27. The first circuit board 25 can also be used to realize the rotation sensing function of the knob 20. For example, a Hall sensor can be provided on the first circuit board 25. When the rotating structure 22 rotates relative to the main body 21, the Hall sensor can sequentially sense the magnetic field of different magnetic parts 231, thereby obtaining the position and / or rotation stroke of the rotating structure 22 relative to the main body 21 according to the sensed magnetic field changes, so that the first circuit board 25 can realize the switch or switching of the corresponding function and realize the rotation sensing function. Of course, the display screen 27 can also be omitted, and the cover 26 can cover the first circuit board 25.

[0046] refer to Figure 3 and Figure 4 As shown, in some embodiments, a plurality of accommodating grooves 211 are provided on the side of the main body 21 facing away from the first circuit board 25, that is, the side facing the button seat 11. The plurality of accommodating grooves 211 are sequentially arranged at intervals along the circumference of the main body 21, and the plurality of magnetic elements 24 are arranged one by one in the accommodating grooves 211. By accommodating the magnetic elements 24 on the surface exposed on the side of the main body 21 facing away from the display screen 27, it is convenient to install and maintain the magnetic elements 24, and it is also beneficial to keep the magnetic elements 24 away from the display screen 27 and the first circuit board 25, thereby reducing the influence of the magnetic field of the magnetic elements 24 on components such as the display screen 27 and the first circuit board 25.

[0047] Combination Figure 2 and Figure 3 As shown, in some embodiments, the cover 26 includes a main body 261 and a connecting portion 262 connected to each other, and the connecting portion 262 may be convexly arranged on the side of the main body 261 facing the main body 21, and the main body 261 and the connecting portion 262 may both be roughly annular. A groove 212 arranged around the first circuit board 25 is provided on the side of the main body 21 facing the cover 26, and the connecting portion 262 is inserted into the groove 212. Such a configuration can improve the structural reliability of the knob 20 and improve the sealing performance between the cover 26 and the main body 21. Further, in some embodiments, the knob 20 may also include a sealing ring 28 arranged at the bottom of the groove 212, and the connecting portion 262 presses the sealing ring 28 against the groove 212. The provision of the sealing ring 28 can further improve the sealing performance between the cover 26 and the main body 21, and prevent moisture or dust from entering the space where the first circuit board 25 is located from between the cover 26 and the main body 21, causing damage to the display screen 27 or the first circuit board 25.

[0048] Combination Figure 5 and Figure 6As shown, in some embodiments, the body portion 261 protrudes from the outside of the connecting portion 262 in the radial direction of the main body 21, and the outer peripheral surface of the body portion 261 can be roughly flush with the outer peripheral surface of the main body 21, or protrude from the outer peripheral surface of the main body 21, and the body portion 261 and the main body 21 are arranged at intervals. The rotating structure 22 includes a rotating portion 221 and a limiting portion 222 protruding from the inner side of the connecting portion 262, and the rotating portion 221 is arranged around the body portion 261 and the main body 21, and at least part of the limiting portion 222 is located between the body portion 261 and the main body 21. Therefore, the end surfaces of the body portion 261 and the main body 21 can limit the two opposite sides of the limiting portion 222, so that the rotating structure 22 is not easy to deviate in the axial direction relative to the main body 21, which is conducive to improving the structural reliability of the knob 20, and is also conducive to further improving the sealing performance between the cover 26 and the main body 21.

[0049] In some embodiments, the inner surface of the rotating structure 22 is provided with an annular groove 2211 opposite to the main body 21, and the magnetic matching member 23 is substantially annular and received in the annular groove 2211. The annular groove 2211 is located on the side of the limiting portion 222 facing away from the main body 261, which can reasonably configure the spatial layout of the various components of the knob 20, thereby improving the space utilization and structural reliability.

[0050] Combination Figure 7 As shown, the specific structure and preparation process of the magnetic matching part 23 in the present application are not limited, as long as there are multiple magnetic parts 231 that are arranged at intervals along the circumference of the main body 21 and can generate a magnetic field. For example, the magnetic matching part 23 can be a plastic soft magnet with multiple magnetic poles. The material of the magnetic matching part 23 can be a fusion of magnetic powder and plastic. The multiple magnetic parts 231 are obtained by magnetizing multiple spaced positions of the magnetic matching part 23. Alternatively, the magnetic matching part 23 can also be obtained by arranging magnetic materials at multiple spaced positions on a plastic, rubber or other substrate. The use of a magnetic matching part 23 including rubber or plastic can enable the magnetic matching part 23 to undergo flexible deformation, which is beneficial to the installation of the magnetic matching part 23 on the rotating structure 22. The magnetic matching part 23 can be fixed to the rotating structure 22 by any applicable method such as gluing, snapping, etc.

[0051] Please see again Figure 2 and Figure 4As shown, in some embodiments, the control element 10 may further include a second circuit board (not shown) disposed in the button seat 11, and the knob 20 may include a conductive element 29 electrically connected to the first circuit board 25 and disposed in the main body 21, the conductive element 29 extends into the button seat 11 and is connected to the second circuit board, and the second circuit board can realize the signal transmission of the first circuit board 25 and the key sensing function of the control element 10. For example, the main body 21 may also be provided with a contact structure 214, the contact structure 214 is inserted in the button seat 11, and when the user presses the knob 20, the contact structure 214 can contact the inductive contact on the second circuit board, so that the second circuit board obtains the user's pressing action, thereby realizing the switch or switching of the corresponding function, and realizing the key sensing function.

[0052] The reciprocating motion of the knob 20 relative to the button seat 11 is also not limited. In some embodiments, the main body 21 is provided with an annular mating portion 213, and the button seat 11 is provided with a mating groove 111 on the side facing the knob 20. The mating portion 213 is inserted into the mating groove 111 and can slide in the mating groove 111 to achieve the reciprocating motion of the knob 20 relative to the button seat 11. Of course, the button seat 11 and / or the knob 20 may also be provided with a limiting element to prevent the knob 20 from detaching from the button seat 11, and an elastic element to drive the knob 20 to reset after the user releases the knob 20, etc. The control element 10 may also be provided with other components to achieve more functions. The above components may also be replaced by other components to achieve corresponding functions, which will not be described in detail in this application.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
