Description

Technical Field

[0001] This utility model relates to the field of automatic water tank cleaning devices, specifically to a button and an automatic water tank cleaning device. Background Technology

[0002] In swimming pool environments, cleaning robots frequently come into contact with water, making the waterproof performance of their buttons particularly important. Insufficient waterproofing can allow moisture to seep into the buttons, causing short circuits or damage. Traditional mechanical button designs in automatic pool cleaning devices, due to the high requirements for waterproofing, typically require the use of soft materials at the button locations to accommodate changes in button position through deformation. However, after prolonged immersion in pool water, soft materials are prone to yellowing and becoming sticky, affecting the button's tactile feel and lifespan. Furthermore, the pressure applied to the buttons is limited by the material properties, making the selection of suitable soft materials challenging. Users may find the buttons too soft or too hard, impacting operational comfort. Utility Model Content

[0003] This application addresses the shortcomings of the prior art by providing a button for an automatic water tank cleaning device. The button comprises a button body, an elastic reset member, and a sensing component. When the button body is subjected to an external force, it moves along a first direction to deform the elastic reset member. When the external force is removed, the elastic reset member drives the button body to move along a second direction, the first direction being opposite to the second direction. The sensing component is correspondingly disposed to the button body so that it can generate a corresponding signal in response to changes in the position of the button body.

[0004] Furthermore, the button also includes a cover structure disposed in the automatic cleaning device of the pool, the cover structure forming a mounting hole, and the button body being slidably mounted in the mounting hole.

[0005] Furthermore, an anti-clogging water flow channel is formed between the button body and the inner wall of the mounting hole.

[0006] Furthermore, the mounting hole includes a first hole segment and a second hole segment, the diameter of the second hole segment being larger than the diameter of the first hole segment, and the anti-clogging water flow channel including the inner wall of the first hole segment, the inner wall of the second hole segment, and the gap between them and the button body; or, the inner wall of the mounting hole forms a groove extending along the first direction, and the anti-clogging water flow channel includes the gap between the inner wall of the groove and the button body.

[0007] Furthermore, when the mounting hole includes a first hole segment and a second hole segment, the diameter of the second hole segment gradually increases along the first direction; and / or when the mounting hole includes a first hole segment and a second hole segment, a first chamfer is provided at the connection between the first hole segment and the second hole segment, the button body protrudes to form a boss that is accommodated in the first hole segment, a second chamfer is provided at the connection between the boss and the button body, and the first chamfer and the second chamfer are spaced apart.

[0008] Furthermore, the button body and / or the cover plate structure further include a limiting part, which limits the movement range of the button body when the button body moves toward the first direction or the second direction; and / or the button body and / or the cover plate structure are further provided with a guide part, which guides the button body to move in the first direction or the second direction.

[0009] Furthermore, the button body is also provided with a sensing element, which is correspondingly arranged with the sensing component so that the sensing component can generate a corresponding signal in response to the position change of the sensing element.

[0010] Furthermore, the sensing element includes a magnet or an iron product.

[0011] Furthermore, the outer contour region of the object to be sensed projected in the first direction at least partially overlaps with the contour region of the sensing component; or the outer contour of the object to be sensed projected in the first direction does not intersect with the contour of the sensing component.

[0012] Furthermore, the sensing component includes at least one of the following elements: a reed switch, a Hall sensor, a magnetoresistive sensor, a magnetometer, and a proximity sensor.

[0013] Another aspect of this application provides an automatic water tank cleaning device, which includes the buttons described in any of the preceding applications.

[0014] Furthermore, the automatic water tank cleaning device includes a sealed chamber, and the sensing component is located inside the sealed chamber.

[0015] The embodiments described in this application have the following beneficial effects:

[0016] In this invention, when the button body is subjected to an external force, it moves along a first direction to deform the elastic reset member. When the external force is removed, the elastic reset member drives the button body to move along a second direction, the first direction being opposite to the second direction. The sensing component is correspondingly arranged with the button body so that the sensing component can generate a corresponding signal in response to the position change of the button body. It eliminates the need for soft materials to match the position change of the button, and the button is simpler to manufacture and assemble, with better reliability and stability, thus improving the user experience.

Detailed Implementation

[0023] The embodiments of this disclosure will now be described with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the protection scope of this application. In the following description, unless otherwise specified, a robot will be used as an example of the automatic pool cleaning device, and a swimming pool will be used as an example of a pool or pool-shaped structure. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0024] First, refer to Figure 1 and Figure 2 The button 100 provided in this application is described by way of example. The button 100 is used in an automatic water tank cleaning device. The button 100 includes: a button body 110, an elastic reset member 120, and a sensing component 130. When the button body 110 is subjected to an external force, it moves along a first direction to deform the elastic reset member 120. When the external force is removed, the elastic reset member 120 drives the button body 110 to move along a second direction, the first direction being opposite to the second direction. The sensing component 130 is correspondingly disposed with the button body 110 so that the sensing component 130 can generate a corresponding signal in response to a change in the position of the button body 110.

[0025] For example, such as Figure 1 As shown, the button body 110 can be the part that is directly contacted and pressed by a user's finger or external force. For example, the button body 110 can be a cap-shaped, rod-shaped, or sheet-shaped structure made of materials such as plastic, metal, or silicone. The button body 110 can receive external force applied by the user (e.g., pressing), and the button body 110 can move in a first direction or in a second direction under the action of force. For example, under the action of external force, the button body 110 can move in the first direction (e.g., pressing). Figure 1 (in the downward direction); when the external force is removed, the button body 110 moves along the second direction under the action of the elastic reset member 120 (e.g., in the downward direction); Figure 1 (The upward direction in the middle).

[0026] The elastic reset element 120 can, for example, provide elasticity to the button body 110 so that when the external force in the first direction is removed, it drives the button body 110 to move in the second direction. The elastic reset element 120 is, for example, located below or to one side of the button body 110. When the button is pressed, the elastic reset element 120 is compressed; when the button is released, the elastic reset element 120 rebounds. The type of elastic reset element 120 can be a compression spring, a sheet spring, etc. The elastic reset element 120 is, for example, made of a metal (such as spring steel) or an elastic material (such as rubber, silicone, etc.).

[0027] In some embodiments, the first direction and the second direction may refer to the direction of movement toward the sensing component and the direction of movement away from the sensing component, respectively, or to the direction of movement of the button body 110 when it is subjected to an external force and when the external force is removed. These two directions are usually opposite. For example, when the button body 110 is subjected to an external force, the button body 110 moves along the first direction. Specifically, when the button body 110 is pressed by the user, it moves along the first direction, compresses the elastic reset member 120, and triggers the sensing component 130. For example, when the user presses the button, the button body 110 moves downward and moves closer to the sensing component 130; this downward movement closer to the sensing component 130 is the first direction. As another example, when the external force is removed, the elastic reset member 120 releases elastic potential energy, driving the button body 110 to move along the second direction. Specifically, after the external force is removed, the elastic reset member 120 enables the button body 110 to move upward away from the sensing component 130 and return to its initial position; this upward movement away from the sensing component 130 is the second direction.

[0028] In some embodiments, the principle by which the sensing component 130 emits an electrical signal may include the button body 110 moving and making direct or indirect physical contact with the sensing component. The sensing component senses the signal of physical contact and then emits a corresponding signal. In this case, the sensing component may include a waterproof micro switch or an underwater contact sensor. In other embodiments, the principle by which the sensing component emits an electrical signal may also include the button body 110 moving and not making physical contact with the sensing component 130. In this case, the sensing component may be configured, for example, include a camera. By detecting whether the button body is within the field of view, the sensing component can emit an electrical signal in response to the change in the position of the button body when there is no physical contact. Alternatively, the sensing component may include a through-beam photoelectric sensor. This through-beam sensor generally includes a transmitter and a receiver. The transmitter is usually an infrared light-emitting diode (LED) or a laser diode, which continuously emits a beam of light of a fixed wavelength (such as infrared light or red light). The receiver is composed of a photosensitive element (such as a photodiode or phototransistor), which receives the light signal from the transmitter in real time and converts it into an electrical signal. The transmitter and receiver need to be aligned and installed to form a straight optical path. When the light path is unobstructed: the light from the transmitting end reaches the receiving end directly, and the receiving end outputs a stable high-level signal (or a specific electrical signal); when an object (such as the button body) obstructs the light path, the object enters the light path, blocking the light beam, the light intensity at the receiving end weakens, and it outputs a low-level signal or triggers a signal change, thereby detecting the presence of the object. In this way, the sensing component can also generate an electrical signal in response to a change in the position of the button body when there is no physical contact. The sensing component 130 can be composed of metal, plastic, and electronic components. The sensing component 130 generates a corresponding signal in response to a change in the position of the button body 110 and sends this signal to the controller. The controller can then control the robot based on the electrical signal, such as activating or switching the robot's cleaning function, or powering the robot on / off.

[0029] The sensing component 130 is correspondingly positioned to the button body 110, meaning that the position and movement of the sensing component 130 correspond to the position and movement of the button body 110, ensuring accurate detection of positional changes in the button body 110 and generating corresponding signals. The sensing component 130 can be mounted below the button body 110 using a fixing device. For example, as... Figure 2 As shown, the sensing component 130 is installed directly below the button body 110. The sensing component 130 can also be installed diagonally below the button body 110, as long as the technical principle of this application can be achieved.

[0030] The sensing component 130 can detect position changes of the button body 110, that is, it can detect position changes of the button body 110 during the pressing and resetting process of the button 100. When the button body 110 moves along a first direction, the sensing component 130 detects this change and generates a corresponding signal; when the button body 110 moves along a second direction, the sensing component 130 detects this change and generates a corresponding signal. The sensing component 130 converts the detected position change into an electrical signal and sends the electrical signal to the controller. The position change of the button body 110 can also be regarded as a triggering action of the sensing component 130, thereby triggering the sensing component 130 to generate a corresponding signal. These signals can be used to trigger the cleaning function of the automatic pool cleaning device or for other control functions. The button of this application no longer needs to use soft materials to match the position change of the button, and the production and assembly are simpler, with better reliability and stability, thus improving the user experience.

[0031] According to the button 100 provided in this application, the button also includes a cover structure 140 disposed in the automatic cleaning device of the pool, the cover structure 140 forming a mounting hole 142, and the button body 110 being slidably mounted in the mounting hole 142.

[0032] In some embodiments, the cover structure 140 is mounted on the automatic pool cleaning device. For example, the cover structure 140 is connected to the automatic pool cleaning device; specifically, the cover structure 140 can be detachably connected to the housing of the automatic pool cleaning device. Alternatively, the cover structure can be integrally formed with the housing of the automatic pool cleaning device. The cover structure 140 can be formed in a predetermined shape to limit, protect, or cover the button body 110. Specifically, the cover structure 140 can be used to mount components of the button 100 (such as the button body 110, the resilient reset member 120, the sensing component 130, etc.). The cover structure 140 can be made of, for example, plastic or metal, and has a certain strength.

[0033] The shape and size of the mounting hole 142 match the button body 110, ensuring that the button body 110 can be smoothly installed and accommodated in the mounting hole 142. The mounting hole 142 can guide the button body 110 to move in a predetermined direction (e.g., along...). Figure 1 (Up and down direction) to ensure the accuracy of button 100 operation. Specifically, the inner wall of the mounting hole 142 may be provided with a guide groove, which allows the button body 110 to move in a predetermined direction. The inner wall of the mounting hole 142 and the button body 110 may also be slidably engaged to ensure smooth movement of the button 100. This application does not restrict the movement of the button body 110 within the mounting hole 142, as long as the movement of the button body 110 can be achieved.

[0034] In some embodiments, an anti-clogging water flow channel 141 is formed between the button body 110 and the inner wall of the mounting hole 142.

[0035] like Figure 1 and Figure 4 As shown, the anti-clogging water flow channel 141 can refer to a channel formed between the button body 110 and the inner wall of the mounting hole 142. One side of the anti-clogging water flow channel 141 can be the inner wall of the mounting hole 142, and the other side of the anti-clogging water flow channel 141 can be the button body 110. Figure 4 As shown in the figure, the dotted line indicates the direction of the anti-clogging water flow channel 141. As shown by the dotted line, the anti-clogging water flow channel 141 extends inward from the upper end of the button body 110 into the button 100, and extends out of the button 100 from the lower end of the button body 110.

[0036] It should be noted that, Figure 4 The lower end of the dotted line is blocked by the limiting part 113, but this does not mean that the water flow, sand or other particles are also blocked by the limiting part. The water flow, sand or other particles can flow out of the button 100 along the anti-blockage water flow channel 141, bypassing the position blocked by the limiting part 113.

[0037] It should also be noted that the anti-clogging water flow channel 141 can be widely present between the inner wall of the button body 110 and the mounting hole 142. Figure 3 The lower end of the anti-clogging water flow channel 141 is shown, which can be located between the button body 110 and the inner wall of the mounting hole 142. (See diagram below.) Figure 3 As shown, a guide groove is formed on the inner wall of the mounting hole 142, and a protrusion facing the guide groove is formed on the outer wall of the button body 110. A portion of the anti-clogging water flow channel 141 may also be located between the guide groove and the protrusion.

[0038] Specifically, sand or other particles can flow in from the upper end of the anti-clogging water flow channel 141 and flow out from the lower end of the anti-clogging water flow channel 141. During the periods when the button body 110 is not pressed or in use, the anti-clogging water flow channel 141 prevents sand or other foreign objects from getting stuck in the button body 110 and prevents sand or other particles from remaining in the button 100, while allowing water flow (whether generated by the automatic pool cleaning device or water from the external environment) to pass through. This reduces the impact of water flow and sand on the operation of the button 100, ensuring the reliability and stability of the button 100 during long-term use.

[0039] According to the button 100 provided in this application, the mounting hole 142 includes a first hole segment 1421 and a second hole segment 1422, the diameter of the second hole segment 1422 is larger than the diameter of the first hole segment 1421, and the anti-clogging water flow channel 141 includes the inner wall of the first hole segment 1421, the inner wall of the second hole segment 1422 and the gap between them and the button body 110; or, the inner wall of the mounting hole 142 forms a groove extending along the first direction, and the anti-clogging water flow channel 141 includes the gap between the inner wall of the groove and the button body 110.

[0040] like Figure 1 As shown, the first hole segment 1421 can be the upper part or inlet portion of the mounting hole 142, and the inner wall of the first hole segment 1421 is cylindrical or nearly cylindrical. For example, the first hole segment 1421 corresponds to the initial position of the button body 110. Specifically, the first hole segment 1421 corresponds to the initial mounting position of the button body 110 and can guide the button body 110 to move along a first direction. The diameter of the first hole segment 1421 is small; for example, the diameter of the first hole segment 1421 matches or is slightly smaller than the diameter of the button body 110. This ensures that the button body 110 can be accommodated in the mounting hole 142, and also leaves a certain gap between the button body 110 and the mounting hole 142 to form an anti-clogging water flow channel 141.

[0041] The second hole segment 1422 can be the lower or bottom portion of the mounting hole 142. The diameter of the second hole segment 1422 can be larger than the diameter of the first hole segment 1421; for example, the area of ​​the second hole segment 1422 is larger than the area of ​​the first hole segment 1421, to accommodate the movement of the button body 110. The diameter of the second hole segment 1422 can, for example, gradually increase along the first direction, so that the cross-section of the second hole segment 1422 forms a trapezoidal or inclined structure. The second hole segment 1422 corresponds to the position of the button body 110 after being subjected to external force, and the second hole segment 1422 can have a certain length along the first direction of the button body 110, so that during the movement of the button 100 along the first direction under the action of external force, the second hole segment 1422 provides sufficient space for the button body 110. Furthermore, the larger diameter of the second hole segment 1422 can increase the volume of water flowing through the anti-clogging water flow channel 141 at the second hole segment 1422, thereby reducing the effect of clogging.

[0042] like Figure 1 and Figure 3As shown, the anti-clogging water flow channel 141 includes the gap between the inner wall of the first hole section 1421 and the button body 110, and the gap between the inner wall of the second hole section 1422 and the button body 110. Specifically, a certain gap is maintained between the inner walls of the first hole section 1421 and the second hole section 1422 and the button body 110 to form a water flow channel; water and sand or other particles can flow through this gap, reducing the impact of water and sand or other particles on the operation of the button 100.

[0043] In another example, the inner wall of the mounting hole 142 forms a groove extending in a first direction, and the anti-clogging water flow channel 141 includes a gap between the inner wall of the groove and the button body 110. Specifically, for example, there is a groove extending in the first direction on the inner wall of the mounting hole 142, the button body 110 moves within the groove, and a certain gap is maintained between the inner wall of the groove and the button body 110 to form a water flow channel; water and sand or other particles can flow through this gap, reducing the impact of water and sand or other particles on button operation.

[0044] According to the button 100 provided in this application, when the mounting hole 142 includes a first hole segment 1421 and a second hole segment 1422, the diameter of the second hole segment 1422 gradually increases along the first direction; and / or when the mounting hole 142 includes a first hole segment 1421 and a second hole segment 1422, a first chamfer is provided at the connection between the first hole segment 1421 and the second hole segment 1422, and the button body 110 protrudes to form a boss 111 that is accommodated in the first hole segment 1421, and a second chamfer is provided at the connection between the boss 111 and the button body 110, with the first chamfer and the second chamfer spaced apart.

[0045] like Figure 1 As shown, the boss 111 can be part of the button body 110. The boss 111 can be disposed on the upper part or top of the button body 110 for cooperating with the first hole segment 1421. The shape of the boss 111 matches the first hole segment 1421, for example, the shape of the boss 111 is cylindrical or similar to a cylinder. The boss 111 can be used to receive external forces. The boss 111 cooperates with the first hole segment 1421, and there is a certain gap between the boss 111 and the inner wall of the first hole segment 1421 to form the upper end of the anti-clogging water flow channel 141.

[0046] For example, such as Figure 1As shown, in the cross-section of button 100, the first chamfer is a bevel, located at the connection between the first hole segment 1421 and the second hole segment 1422. This bevel forms a first predetermined angle with the first direction described above. For example, in the cross-section of button 100, the first chamfer can be a rounded corner (the connection between the first hole segment 1421 and the second hole segment 1422 is provided with a rounded corner, which protrudes towards the button body 110). The first chamfer can guide the button body 110 to smoothly enter the mounting hole 142, reducing the jamming phenomenon during the movement of the button body 110, and can also play a certain limiting role, that is, limiting the degree of movement of the button body 110 along the second direction described above.

[0047] For example, such as Figure 1 As shown, in the cross-section of button 100, the second chamfer is a bevel and is provided at the connection between the boss 111 and the button body 110. The bevel forms a second predetermined angle with the first direction mentioned above. The second predetermined angle may be the same as or different from the first predetermined angle. For example, in the cross-section of button 100, the second chamfer may be a rounded corner, which is recessed into the interior of button body 110.

[0048] The purpose of providing the first and second chamfers is twofold: firstly, to help form an anti-clogging water flow channel 141 between the mounting hole 142 and the button body 110; and secondly, to provide smooth transition surfaces for both the mounting hole 142 and the button body 110, allowing the mounting hole 142 to limit the movement of the button body 110 and preventing or reducing friction between the button body 110 and the inner wall of the mounting hole 142 during movement. The size and position of the first and second chamfers can be selected within a reasonable range, and this application does not impose specific limitations on them, as long as the above-mentioned technical principles are achieved.

[0049] According to the button 100 provided in this application, the button body 110 and / or the cover structure 140 further include a limiting part, which limits the movement range of the button body 110 when the button body 110 moves toward the first direction or the second direction; and / or the button body 110 and / or the cover structure 140 are further provided with a guide part, which guides the button body 110 to move in the first direction or the second direction.

[0050] The limiting part may be located on the button body 110 and / or on the cover structure 140. The limiting part is a mechanical structure, for example, made of metal or high-strength plastic, with sufficient strength and wear resistance. The limiting part is used to limit the range of movement of the button body 110, preventing the button body 110 from exceeding the predetermined range of movement during operation.

[0051] like Figure 3 and Figure 4 As shown, when the button body 110 moves along the first direction (press direction) or the second direction (reset direction), the limiting part 113 can limit the movement range of the button body 110. The limiting part 113 may include, for example, a limiting part latch or a limiting block. The limiting part 113 may be provided on the side or bottom of the button body 110. When the limiting latch performs the limiting function, the limiting latch can be engaged at the opening of the mounting hole 142; or the limiting block can block the displacement of the button body 110.

[0052] It is understandable that, such as Figure 3 and Figure 4 As shown, the limiting part 143 can be provided, for example, on the inner wall of the mounting hole 142. The limiting part 143 corresponds to the movement path of the button body 110, and the limiting part 143 cooperates with the side or bottom of the button body 110. When the button body 110 moves, the limiting part 143 contacts the button body 110, limiting the movement range of the button body 110. The limiting part 143 can prevent the button body 110 from being excessively deformed or damaged when subjected to external force.

[0053] like Figure 3 and Figure 4 As shown, the limiting part may include a limiting buckle and a limiting block. The limiting buckle may be provided on the side or bottom of the button body 110, and the limiting block may be provided on the inner wall of the mounting hole 142. The limiting buckle and the limiting block work together to limit the movement range of the button body 110 (for example, limit the movement range of the button body 110 along the first and second directions mentioned above), ensuring smooth operation of the button body 110, thereby preventing the button body 110 from moving excessively when subjected to external force, and avoiding damage or malfunction of the button body 110 due to excessive movement.

[0054] It should be noted that the exemplary description of the types and installation positions of the limiting parts above is not an exhaustive list. The types and installation positions of the limiting parts protected by this application are not limited to those listed above. Those skilled in the art can adjust the limiting parts according to the actual situation, as long as the technical principles of this application can be realized.

[0055] According to the button 100 provided in this application, the button body 110 is further provided with a sensor 112 to be sensed. The sensor 112 to be sensed is correspondingly arranged with the sensing component 130 so that the sensing component 130 can generate a corresponding signal in response to the position change of the sensor 112 to be sensed.

[0056] The sensing element 112 can be a specific component on the button body 110. The sensing element 112 cooperates with the sensing component 130, enabling the sensing component 130 to detect changes in the position of the button body 110. The sensing element 112 can be, for example, a physical structure or component. For instance, in the aforementioned embodiment using a camera as the sensing component, the sensing component can be a reflective element; in the aforementioned embodiment using a through-beam photoelectric sensor as the sensing component, the sensing component can be a light-absorbing element. Changes in the position of the sensing element 112 can be detected by the sensing component 130, which can convert these changes into electrical signals.

[0057] According to the button 100 provided in this application, the sensing element 112 includes a magnet or an iron product.

[0058] Magnets possess a magnetic field, which can be detected by the sensing component 130. When the button body 110 moves, the change in the magnet's position causes a change in the magnetic field around the magnet, which is then detected by the sensing component 130. The magnet can be a small permanent magnet, and its shape can be circular, square, or other shapes suitable for mounting on the button body 110. Iron objects are magnetized in a magnetic field, thereby changing the distribution of the magnetic field. In this embodiment, the sensing component 130 has the function of detecting changes in the magnetic field, specifically including a magnetic induction sensor. When the button is pressed, the sensing element 112 approaches the sensing component 130, and the change in the magnetic field around the sensing component 130 is detected, thus generating an electrical signal.

[0059] The sensing element 112 can have various shapes. The specific shape is not specifically limited in this application, as long as it can adapt to the type and detection of the sensing component 130.

[0060] According to the button 100 provided in this application, the sensing component 130 includes at least one of the following elements: a reed switch, a Hall sensor, a magnetoresistive sensor, a magnetometer, and a proximity sensor.

[0061] The sensing component 130 of the button may include various types of sensors, which are used to detect changes in the position of the button body 110 and generate corresponding signals.

[0062] For example, a reed switch is a magnetically sensitive switch consisting of two or more reeds sealed in a glass tube. When an external magnetic field approaches, the reeds are magnetized and attracted, thus conducting the circuit. The reeds inside the reed switch attract under the influence of an external magnetic field, forming a conductive path. For example, when a magnet on the button body 110 approaches the reed switch, the reed switch conducts, generating an electrical signal. Reed switches are very sensitive to changes in magnetic fields. When not conducting, a reed switch consumes almost no electrical energy. Reed switches can detect the pressed and reset states of a button.

[0063] A Hall sensor is a sensor based on the Hall effect. It detects changes in a magnetic field and converts these changes into an electrical signal. By detecting changes in the magnetic field, a Hall sensor generates a voltage signal proportional to the magnetic field strength. Hall sensors can detect even weak changes in magnetic fields.

[0064] A magnetoresistive sensor is a sensor based on the magnetoresistive effect, capable of detecting changes in magnetic fields and converting these changes into changes in resistance. When a magnetic field acts on a magnetoresistive material, the material's resistance changes. The magnetoresistive sensor generates an electrical signal proportional to the magnetic field strength by detecting this change in resistance. Magnetoresistive sensors can detect weak changes in magnetic fields and can also be used to detect changes in the position of a button.

[0065] A magnetometer is a sensor used to measure the strength and direction of a magnetic field. By detecting the strength and direction of the magnetic field, a magnetometer generates a corresponding electrical signal. It outputs the strength of three components of the magnetic field (X, Y, and Z axes), which can be used to determine the direction and strength of the magnetic field. Magnetometers can accurately measure the strength and direction of magnetic fields and can also be used to detect changes in the position of a button.

[0066] A proximity sensor is a sensor that detects the approach or departure of an object. It emits and receives electromagnetic waves to detect the object's proximity or departure. When an object approaches the sensor, the sensor detects the change in electromagnetic waves and generates an electrical signal. Proximity sensors are used to detect changes in the position of a button.

[0067] Specifically, magnets or ferrous objects are typically mounted on the side or bottom of the button body 110 to ensure effective interaction with the sensing component 130 during button pressing and reset. The magnets or ferrous objects can be mounted on the button body 110 by adhesive bonding, embedding, or mechanical fixing. When a user presses the button body 110, it moves along a first direction, and the sensing element 112 also moves. The sensing component 130 detects the position change of the sensing element 112, generates an electrical signal, and sends it to the controller. After the user removes the external force, the elastic reset element 120 releases its elastic potential energy, the button body 110 moves along a second direction, and returns to its initial position. The sensing component 130 detects the position change of the sensing element 112, generates an electrical signal, and sends it to the controller.

[0068] According to the button 100 provided in this application, the outer contour area of ​​the sensor 112 projected in the first direction at least partially overlaps with the contour area of ​​the sensing component 130; or the outer contour of the sensor 112 projected in the first direction does not intersect with the contour of the sensing component 130.

[0069] like Figure 1As shown, the sensing component 130 is disposed below the button body 110. The outer contour area projected by the sensing element 112 in the first direction at least partially overlaps with the contour area of ​​the sensing component 130. During button pressing, the sensing element 112 enters the detection range of the sensing component 130. The sensing component 130 can detect the position change of the sensing element 112 and generate a corresponding signal. Specifically, when the button is pressed, the sensing element 112 enters the detection range of the sensing component 130, and the sensing component 130 detects the change in magnetic field or physical contact, generating an electrical signal.

[0070] like Figure 2 As shown, the sensing component 130 is disposed on the side of the button body 110. The outer contour of the sensor 112 projected in the first direction does not intersect with the contour of the sensing component 130, which can reduce the length of the button body 110 extending in the first direction and reduce the volume occupied by the button body 110 in the first direction.

[0071] This application also provides an automatic pool cleaning device, which includes the button 100 described in any of the above applications.

[0072] According to the automatic water tank cleaning device provided in this application, the automatic water tank cleaning device includes a sealed chamber 200, and the sensing component 130 is located inside the sealed chamber 200.

[0073] like Figure 1 As shown, the sealed chamber 200 is an enclosed space in the automatic pool cleaning device used to house and protect the sensing component 130. The sealed chamber 200 ensures that the sensing component 130 can function properly in the underwater environment while preventing moisture and dirt from entering.

[0074] The sealed chamber 200 is made of, for example, a waterproof and corrosion-resistant material, such as plastic or composite material. The shape of the sealed chamber 200 is, for example, cuboid or cylindrical. The material and sealing properties of the sealed chamber 200 prevent dirt and particulate matter from entering, reducing wear and tear and the risk of malfunction of the sensing component 130. The sensing component 130 within the sealed chamber 200 remains clean and stable, improving the accuracy and reliability of the sensing component 130 in detecting positional changes of the sensing element 112, and ensuring the normal operation of the automatic water tank cleaning device. It is understood that when the sensing component 130 uses optical principles to detect the button body, a portion of the chamber wall of the sealed chamber 200 can be made translucent to facilitate the operation of the sensing component 130.
