Electric cleaning brush and control method thereof

Abstract

The invention relates to an electric cleaning brush and a control method thereof. The electric cleaning brush comprises a machine shell, a pressure sensing piece and a motor. The machine shell comprises a handle part, and the pressure sensing piece is arranged on the handle part and used for detecting a pressure value. The motor is arranged in the machine shell, electrically connected with the pressure induction piece and configured to be capable of adjusting the rotating speed of the motor based on the pressure value. According to the electric cleaning brush, the pressure value capable of representing the force of a user holding the handle part is detected, and the rotating speed of the motor is adjusted according to the pressure value. In this way, the electric cleaning brush can adjust the rotating speed of the motor in a self-adaptive mode according to the force of a user holding the handle. In other words, when the user needs to change the cleaning strength according to factors such as different use scenes or cleaning conditions, the user does not need to stop cleaning and operate related keys, the rotating speed of the motor can be adjusted only by changing the holding force, and the cleaning device is very convenient and does not affect the continuity of the cleaning process.

Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to an electric cleaning brush and a control method thereof. Background Art

[0002] To improve cleaning effectiveness and reduce user workload, electric cleaning brushes are becoming increasingly popular. They are suitable for cleaning surfaces such as kitchenware, tableware, baseboards, glass, household surfaces, and kitchen stoves. Some electric cleaning brushes feature multiple speed settings to meet different cleaning needs and varying levels of dirt.

[0003] However, in the related art, the gear switching of the electric cleaning brush is achieved through a special gear button. When the user uses the electric cleaning brush for cleaning, he or she also needs to operate the special button to switch the gear, which is not convenient. Summary of the Invention

[0004] Based on this, it is necessary to provide an electric cleaning brush and a control method thereof that can more conveniently achieve the change of motor speed in order to address the above-mentioned problems.

[0005] An electric cleaning brush comprising:

[0006] a housing, including a handle portion;

[0007] A pressure sensor, provided on the handle portion, for detecting a pressure value; and

[0008] The motor is disposed in the housing and electrically connected to the pressure sensing element, and is configured to be able to adjust its own rotation speed based on the pressure value.

[0009] The electric cleaning brush detects a pressure value that indicates the strength of the user's grip on the handle and adjusts the motor speed based on this pressure value. In this way, the electric cleaning brush can adaptively adjust the motor speed based on the strength of the user's grip on the handle. In other words, when the user needs to change the cleaning intensity based on different usage scenarios or cleaning conditions, there is no need to stop cleaning and press the relevant buttons. Instead, the user can adjust the motor speed by simply changing the grip strength, which is very convenient and does not affect the continuity of the cleaning process.

[0010] In one embodiment, the pressure sensing element is arranged along the circumference of the handle portion in the longitudinal direction.

[0011] In this way, when the user grips the handle portion circumferentially, pressure is applied to the pressure sensing element in the circumferential direction, thereby detecting the pressure value more fully and evenly, thereby improving the accuracy of the detection result.

[0012] In one embodiment, the pressure sensing element is a pressure sensing ring, and surrounds the entire circumference of the handle in the longitudinal direction.

[0013] This allows the pressure sensor to cover the entire circumference of the handle. Regardless of the angle at which the user grips the handle, the pressure generated by the grip can be detected by the pressure sensor, more accurately measuring the overall pressure distribution when the user is gripping. Furthermore, the pressure ring design better adapts to the contours of the palm, improving grip comfort and ultimately enhancing the user experience.

[0014] In one embodiment, the pressure sensing element is embedded in the handle portion, and at least a portion of its surface is exposed to the outer surface of the handle portion; the surface of the pressure sensing element has a protrusion, and the protrusion is protruded relative to the outer surface of the handle portion.

[0015] In this way, the pressure sensing part is stably installed on the handle part by being embedded, and it has a protrusion protruding from the outer surface of the handle part. The protrusion can better contact the handle part held by the user to transmit and sense the pressure applied by the user, which helps to improve the accuracy of the detection results.

[0016] In one embodiment, the pressure sensing element includes at least one of a piezoelectric sensor, a capacitive sensor, and a piezoresistive sensor.

[0017] In this way, the pressure sensing element can accurately detect the pressure value with the help of the sensor it contains. In addition, the combined use of multiple sensors can also improve the accuracy of the detection results and reduce the influence of a single external interference factor.

[0018] In one embodiment, the electric cleaning brush further includes a control component, which is electrically connected to the pressure sensing component and the motor and is configured to control the rotation speed of the motor based on the pressure value detected by the pressure sensing component.

[0019] In this way, the data measured by the pressure sensing element can be processed by the control element, and the control element can generate a control signal and control the speed of the motor accordingly, making the control process more accurate and automated.

[0020] In one embodiment, the electric cleaning brush further includes at least two brush heads of different specifications, and all of the brush heads are selectively connected to the motor in a detachable transmission manner.

[0021] This allows users to install the appropriate brush head based on different usage scenarios and levels of dirt, helping to expand the applicability of the electric cleaning brush. The electric cleaning brush matches the speed gear to each scenario, brush head, and dirt level, ultimately determining the gripping force for each situation, ensuring adaptive scheduling of the motor and brush head speeds.

[0022] A control method for an electric cleaning brush, wherein the electric cleaning brush is the electric cleaning brush described above, the control method comprising:

[0023] Obtaining a pressure value detected by the pressure sensing element;

[0024] The speed of the motor is controlled based on the pressure value.

[0025] The control method for the electric cleaning brush described above obtains a pressure value that represents the strength with which the user grips the handle and adjusts the motor speed based on this pressure value. In this way, the electric cleaning brush can adaptively adjust the motor speed based on the strength with which the user grips the handle. In other words, when the user needs to change the cleaning intensity based on different usage scenarios or cleaning situations, they do not need to stop cleaning and press the relevant buttons; instead, they can simply adjust the motor speed by changing the grip strength, which is very convenient and does not affect the continuity of the cleaning process.

[0026] In one embodiment, the step of controlling the speed of the motor based on the pressure value includes:

[0027] identifying a preset pressure range to which the pressure value belongs;

[0028] Controlling the motor to switch to a speed gear that matches the preset pressure range;

[0029] There are at least two preset pressure ranges, and different preset pressure ranges match different speed gears.

[0030] In this way, when the pressure value generated by the user gripping the handle is within a preset range, the motor can operate at the same speed gear, which helps to improve the stability of the motor operation and thus improve the stability of the cleaning process.

[0031] In one embodiment, all the preset pressure ranges do not overlap with each other, and the speed of the motor at the speed gear matching the preset pressure range is positively correlated with the minimum value of the preset pressure range.

[0032] This way, when facing more stubborn stains or other targets that require more aggressive cleaning, the user can tighten their grip to drive the motor to a higher speed gear for improved cleaning results. This method aligns with the actual cleaning habits of most users: when faced with a deeper clean, users will naturally increase the force on the cleaning tool and hold it more tightly, thereby judging the difficulty of cleaning.

[0033] In one embodiment, the preset pressure range includes a first preset pressure range, a second preset pressure range, and a third preset pressure range, the first preset pressure range is [1N-5N], the second preset pressure range is (5N-10N], and the third preset pressure range is (10N-XN); wherein X>10.

[0034] Thus, when the user holds the handle lightly, the motor can operate at a low speed gear. When the user holds the handle moderately, the motor can operate at a medium speed gear. When the user holds the handle firmly, the motor can operate at a high speed gear. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the character " / " in this article generally indicates that there is an "or" relationship between the associated objects before and after it. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, four, five, etc., unless otherwise clearly and specifically defined.

[0049] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0050] See also Figure 1 and Figure 2 An electric cleaning brush 100 provided in one embodiment of the present application includes a housing 10, a pressure sensor 20, and a motor 30. The housing 10 includes a handle 11, and the pressure sensor 20 is disposed on the handle 11 and is used to detect pressure. The motor 30 is disposed within the housing 10 and electrically connected to the pressure sensor 20. The motor 30 is configured to adjust its rotational speed based on the pressure.

[0051] To function properly, the electric cleaning brush 100 includes conventional components, such as a brush head 40. The brush head 40 is in transmission connection with the motor 30, enabling it to perform cleaning actions, such as rotation and reciprocating motion, driven by the motor 30. Details are omitted here. In one embodiment, the electric cleaning brush 100 is used for household cleaning. In other embodiments, the electric cleaning brush 100 can also be used for cleaning teeth, etc., without further limitation.

[0052] As can be understood, the handle 11 of the housing 10 is intended for the user to grip when using the electric cleaning brush 100. The pressure value detected by the pressure sensor 20 represents the pressure exerted on the handle 11. This pressure is the pressure exerted on the handle 11 by the user gripping the electric cleaning brush 100. In other words, the pressure value detected by the pressure sensor 20 represents the strength with which the user grips the handle 11.

[0053] The motor 30 can be electrically connected to the pressure sensing element 20 directly or indirectly. The motor's speed is adjusted based on the pressure value, and this speed can refer to the speed of the motor when it is idling. The speed of the motor 30 can be adjusted by adjusting its operating voltage and / or operating current.

[0054] The electric cleaning brush 100 detects a pressure value that indicates the strength with which the user grips the handle 11 and adjusts the speed of the motor 30 accordingly. In this way, the electric cleaning brush 100 can adaptively adjust the speed of the motor 30 based on the strength of the user's grip on the handle. In other words, when the user needs to change the cleaning intensity based on different usage scenarios or cleaning situations, they do not need to stop cleaning and press the relevant buttons; instead, they can simply adjust the grip strength to adjust the speed of the motor 30. This is very convenient and does not affect the continuity of the cleaning process.

[0055] Furthermore, the motor 30 has at least two speed gears, each corresponding to a different speed. Each speed gear matches a preset pressure range. When the pressure value detected by the pressure sensor 20 falls within a preset pressure range, the motor 30 switches to the speed gear that matches the preset pressure range. The larger the minimum value of the preset pressure range, the higher the speed corresponding to the matching speed gear. Alternatively, the speed of the motor 30 is positively correlated with the pressure value detected by the pressure sensor 20.

[0056] In this way, when the user is faced with more stubborn stains or other targets that require more powerful cleaning, they can drive the motor 30 to run at a higher speed by gripping it tightly to improve the cleaning effect. This method is consistent with the actual cleaning habits of most users. That is, when faced with a deeper cleaning, the user will naturally increase the force applied to the cleaning tool and hold the cleaning tool more tightly, thereby judging the difficulty of cleaning.

[0057] In some embodiments, the pressure sensing element 20 is disposed along the circumference of the handle portion 11 in the longitudinal direction.

[0058] It is understandable that the coverage area of ​​the pressure sensing element 20 can be adjusted according to the size and shape of the handle portion 11, as long as it can ensure that the user can apply pressure to the pressure sensing element 20 over a large range and evenly during the gripping process.

[0059] In this way, when the user grips the handle portion 11 circumferentially, pressure is applied to the pressure sensing element 20 in the circumferential direction, thereby detecting the pressure value more fully and evenly, thereby improving the accuracy of the detection result.

[0060] Furthermore, the pressure sensing element 20 is a pressure sensing ring, and surrounds the entire circumference of the handle portion 11 in the longitudinal direction.

[0061] It is understandable that the number of the pressure sensing rings can be 1, 2 or more. When the number of the pressure sensing rings is not less than 2, the pressure sensing rings are arranged at intervals along the longitudinal direction of the handle portion 11.

[0062] In this way, the pressure sensing element 20 can cover the entire circumference of the handle portion 11. Regardless of the angle at which the user grips the handle portion 11, the pressure generated by the grip can be detected by the pressure sensing element 20, and the overall pressure distribution of the user's grip can be more accurately detected. In addition, the design of the pressure sensing ring can better adapt to the contours of the palm, improving grip comfort and thus enhancing the user experience.

[0063] In some other embodiments, the pressure sensing element 20 may further include a plurality of independent pressure sensing points provided on the surface of the handle portion 11, and detect pressure by collecting pressure through all the pressure sensing points, etc., which is not specifically limited here.

[0064] In some embodiments, the pressure sensing element 20 is embedded in the handle 11, and at least a portion of its surface is exposed to the outer surface of the handle 11. The pressure sensing element 20 has a protrusion (not shown) on its surface, which protrudes relative to the outer surface of the handle 11.

[0065] Understandably, the projection can be a circle, an ellipse, a hemispherical, a cone or an irregular shape or other shapes that are suitable for ergonomics, as long as the curve that can better fit the palm of the hand is obtained. In addition, each projection can be designed into different shapes.

[0066] In this way, the pressure sensing part 20 is stably installed on the handle part 11 by being embedded, and it has a protrusion protruding from the outer surface of the handle part 11. The protrusion can better contact with the user holding the handle part 11 to transmit and sense the pressure applied by the user, which helps to improve the accuracy of the detection results.

[0067] In some other embodiments, the pressure sensing element 20 may also be disposed in the handle portion 11 to sense the pressure value transmitted through the handle portion 11 .

[0068] In some embodiments, the pressure sensing element 20 includes at least one of a piezoelectric sensor, a capacitive sensor, and a piezoresistive sensor.

[0069] Piezoelectric sensors measure pressure changes through the piezoelectric effect of materials and offer fast response times. Capacitive sensors detect pressure changes by changing capacitance, offering high sensitivity and resolution. Piezoresistive sensors measure pressure through changes in resistance, offering excellent stability and adaptability to a wide range of environmental conditions.

[0070] In this way, the pressure sensing element 20 can accurately detect the pressure value with the help of the sensor it contains. In addition, the combined use of multiple sensors can also improve the accuracy of the detection results and reduce the influence of a single external interference factor.

[0071] In some other embodiments, the pressure sensing element 20 may also include a strain sensor, an optical fiber / photoelectric pressure sensor, etc., which are not specifically limited here.

[0072] In some embodiments, the electric cleaning brush 100 includes at least two brush heads 40 of different specifications, and all of the brush heads 40 are selectively connected to the motor 30 in a detachable transmission manner.

[0073] It is understandable that different specifications of brush heads 40 may refer to different sizes, shapes, materials, etc. This solution is mainly used in electric cleaning brushes 100 products, especially in products with replaceable cleaning brush heads. First, it is required that more than two brush heads 40 can be replaced.

[0074] In this way, users can install the corresponding brush head 40 according to different usage scenarios and different levels of dirt, which helps to expand the applicability of the electric cleaning brush 100. According to different scenarios, different brush heads 40 and different levels of dirt, the electric cleaning brush 100 matches the speed gear, ultimately determining the grip force in each case, ensuring adaptive scheduling of the speed of the motor 30 and brush head 40.

[0075] In some other embodiments, the brush head 40 of the electric cleaning brush 100 may also be non-detachable and fixedly connected to the motor 30, which is not specifically limited here.

[0076] In some embodiments, the electric cleaning brush 100 further includes a control component 50 , which is electrically connected to the pressure sensing component 20 and the motor 30 and is configured to control the rotation speed of the motor 30 based on the pressure value detected by the pressure sensing component 20 .

[0077] The control component 50 may be, but is not limited to, a control mainboard, which can receive and process data measured by the pressure sensing component 20 and generate a control signal for controlling the working gear of the motor 30 based on the processing result.

[0078] In this way, the data measured by the pressure sensing element 20 can be processed by the control element 50, and the control element 50 generates a control signal and controls the speed of the motor 30 accordingly, making the control process more accurate and automated.

[0079] In other embodiments, the pressure sensing element 20 can also directly output an electrical signal to control the operation of the motor 30. For example, the pressure sensing element 20 is connected in series between the motor 30 and the battery 70 or an external power supply as a pressure-sensing resistor, thereby directly affecting the speed of the motor 30 through its pressure changes.

[0080] Please also refer to Figure 3 In some embodiments, the electric cleaning brush 100 further includes a switch button 60 , which is disposed on the housing 10 and at least partially exposed on the surface of the housing 10 , for controlling the start and stop of the motor 30 .

[0081] In some embodiments, the electric cleaning brush 100 further includes a battery 70 . The battery 70 is disposed in the housing 10 and is electrically connected to the pressure sensing element 20 and / or the control element 50 .

[0082] It is understood that the battery 70 is used to power the electric cleaning brush 100. Specifically, the voltage or current output by the battery 70 can be adjusted by the pressure sensor 20 or the control unit 50 based on the pressure value, and then output to the motor 30, so that the motor 30 operates at the corresponding speed gear.

[0083] Specifically, the housing 10 further includes a main body 13 connected to the handle 11 , the motor 30 is disposed in the main body 13 , the battery 70 and the control component 50 are disposed in the handle 11 , and the switch button 60 is disposed on the handle 11 .

[0084] Please also refer to Figure 4 Specifically, the housing 10 has a charging port 111. The type of charging port 111 can be, but is not limited to, a USB-A, Micro USB, USB-A, Lightning, AC / DC port, or magnetic port. The charging port 111 can be located at the end of the handle 11 away from the main body 13. The housing 10 also includes a charging cover 15 that is removably mounted on the end of the handle 11. Alternatively, the electric cleaning brush 100 can further include a charging coil located within the housing 10 to enable wireless charging of the battery 70.

[0085] In some other embodiments, the electric cleaning brush 100 may not have a built-in battery 70, but may be powered externally; or, the electric cleaning brush 100 may include a battery 70 and a power cord for external power supply, which is not specifically limited here.

[0086] In some embodiments, the electric cleaning brush 100 further includes an indicator light 80 , which is electrically connected to the control component 50 and is used to indicate at least one of the start and stop of the motor 30 , the speed of the motor 30 , and the speed gear of the motor 30 .

[0087] In this way, the user can know the working status of the motor 30 according to the indicator light 80.

[0088] Please also refer to Figure 5 The present application also provides a control method for an electric cleaning brush, wherein the electric cleaning brush is the electric cleaning brush described above, and the control method includes:

[0089] S100: Obtain the pressure value detected by the pressure sensing element.

[0090] The pressure value detected by the pressure sensor is the pressure on the handle. When using an electric cleaning brush, this pressure is the pressure exerted on the handle by the user when gripping the handle. In other words, the pressure value detected by the pressure sensor can represent the strength with which the user grips the handle.

[0091] S300 : Control the rotation speed of the motor based on the pressure value.

[0092] The speed of the motor is adjusted based on the pressure value, and the speed may refer to the speed of the motor when it is idling. The speed of the motor may be adjusted by adjusting its operating voltage and / or operating current.

[0093] The control method for the electric cleaning brush described above obtains a pressure value that represents the strength with which the user grips the handle and adjusts the motor speed based on this pressure value. In this way, the electric cleaning brush can adaptively adjust the motor speed based on the strength with which the user grips the handle. In other words, when the user needs to change the cleaning intensity based on different usage scenarios or cleaning situations, they do not need to stop cleaning and press the relevant buttons; instead, they can simply adjust the motor speed by changing the grip strength, which is very convenient and does not affect the continuity of the cleaning process.

[0094] Please also refer to Figure 6 In some embodiments, the step of controlling the speed of the motor based on the pressure value, i.e., step S300, includes:

[0095] S310: Identify the preset pressure range to which the pressure value belongs.

[0096] S330: Control the motor to switch to a speed gear that matches the preset pressure range.

[0097] There are at least two preset pressure ranges, and different preset pressure ranges match different speed gears. It is understandable that the speed of the motor is different at different speed gears.

[0098] Specifically, the acquired pressure value is matched with each preset pressure range, and the preset pressure range to which the pressure value belongs is determined to be the current range; and the motor is controlled to switch to a speed gear that matches the current range.

[0099] In this way, when the pressure value generated by the user gripping the handle is within a preset range, the motor can operate at the same speed gear, which helps to improve the stability of the motor operation and thus improve the stability of the cleaning process.

[0100] In some embodiments, all preset pressure ranges do not overlap with each other, and the speed of the motor at a speed gear matching the preset pressure range is positively correlated with the minimum value of the preset pressure range.

[0101] In other words, the larger the minimum value of the preset pressure range is, the higher the speed corresponding to the matching speed gear is.

[0102] This way, when facing more stubborn stains or other targets that require more aggressive cleaning, the user can tighten their grip to drive the motor to a higher speed gear for improved cleaning results. This method aligns with the actual cleaning habits of most users: when faced with a deeper clean, users will naturally increase the force on the cleaning tool and hold it more tightly, thereby judging the difficulty of cleaning.

[0103] Furthermore, the preset pressure range includes a first preset pressure range, a second preset pressure range, and a third preset pressure range, the first preset pressure range is [1N-5N], the second preset pressure range is (5N-10N], and the third preset pressure range is (10N-XN); wherein X>10.

[0104] The speed gear that matches the first preset pressure range is the first speed gear, the speed gear that matches the second preset pressure range is the second speed gear, and the speed gear that matches the third preset pressure range is the third speed gear. The speed of the motor corresponding to the first speed gear is a, the speed of the motor corresponding to the second speed gear is b, and the speed of the motor corresponding to the third speed gear is c, then a<b<c. ​​Among them, the first speed gear can be called a low speed gear, the second speed gear can be called a medium speed gear, and the third speed gear can be called a high speed gear.

[0105] Thus, when the user holds the handle lightly, the motor can operate at a low speed gear. When the user holds the handle moderately, the motor can operate at a medium speed gear. When the user holds the handle firmly, the motor can operate at a high speed gear.

[0106] In different scenarios, brush heads and dirt conditions, generally speaking, the more difficult the surface is to clean, the tighter the user can grip the handle, and the correspondingly higher the speed of the motor and brush head, thereby ensuring the cleaning effect.

[0107] In order to facilitate understanding of the control method of the electric cleaning brush of the present application, a specific application example is provided below for illustration. In the specific application example, the control method of the electric cleaning brush of the present application includes the following steps:

[0108] 1. According to different user scenarios, users can select the matching brush head from the accessories for installation;

[0109] 2. Press the switch button to start the electric cleaning brush;

[0110] 3. Entering the operation stage: the battery provides power to the control unit, the indicator light lights up, the circuit is connected, the motor starts to rotate, driving the brush head to rotate and start cleaning; preferably, the cleaning speed of the motor is ≥200±30r / min;

[0111] 4. Entering the adjustment stage: During actual cleaning, due to the different levels of dirtiness, the pressure sensor detects the user's grip on the handle during the cleaning process and assesses the difficulty of the user's cleaning based on the strength. The pressure value is fed back to the control panel to automatically adjust the motor speed. Preferably, the motor has three speed switching gears: (1) First speed gear: pressure value is between 1N and 5N; (2) Second speed gear: pressure value is between 5N and 10N; (3) Third speed gear: pressure value is greater than 10N.

[0112] 5. Keep cleaning;
