Description
Technical Field
[0001] This invention relates to the field of cleaning appliance technology, and in particular to a method for stopping and pausing cleaning equipment, a cleaning component, and the cleaning equipment itself. Background Technology
[0002] With the continuous development of smart technology, various types of smart home appliances are emerging, providing people with a more convenient, efficient, and comfortable living experience. Among them, the emergence of intelligent cleaning equipment such as intelligent robots has solved tedious cleaning tasks for people, while also improving productivity and work efficiency.
[0003] As a core component of cleaning equipment, the side-sweeping unit is typically installed on the edge of the bottom surface of the equipment to clean often-overlooked areas such as corners and walls, ensuring thorough cleaning. However, the stopping position of existing side-sweeping units is highly random. When the cleaning equipment returns to the base station, the stopping position of the side brushes is unpredictable and can not be controlled. This can lead to the side-sweeping unit coming into contact with structural ribs of the base station, causing the brush bristles to deform under pressure, or being accidentally damaged by the hair-cutting structures on the base station, resulting in damage to the side-sweeping unit.
[0004] In view of this, it is indeed necessary to provide a method for stopping and pausing cleaning equipment, a cleaning component, and a cleaning equipment to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a method for stopping a cleaning device at a preset stop position.
[0006] To achieve the above objectives, the present invention provides a method for side-sweeping and stopping a cleaning device. The cleaning device is equipped with a side-sweeping assembly, which includes a side brush, a trigger, and a detection device. The side brush includes N bristles, where N ≥ 1. The method for side-sweeping and stopping includes the following steps:
[0007] Obtain the preset stop position of the side brush;
[0008] The positional relationship between the bristles, the trigger, and the detection device is determined based on the preset stop position, so that the initial position of the bristles is at the preset stop position;
[0009] When the preset stopping condition is reached, the detection device detects the trigger to trigger a stop signal. The stop signal is used to stop the brush bristles from rotating at a specified stop position, wherein the specified stop position is related to the preset stop position.
[0010] As a further improvement of the present invention, the specified stop position is a preset stop position, or the specified stop position is a rotation of M 360° / N based on the preset stop position, where M is a positive integer.
[0011] As a further improvement of the present invention, one of the brush bristles is defined as the initial brush bristle. The step of determining the positional relationship between the brush bristles, the trigger, and the detection device based on the preset stop position, such that the initial position of the brush bristle is at the preset stop position, includes:
[0012] Determine the size of a first angle between the detection device and the trigger, and adjust the size of a second angle between the trigger and the initial bristles according to the size of the first angle, so that the initial position of the bristles is at the preset stop position, or...
[0013] The size of the second angle between the trigger and the initial bristles is determined, and the size of the first angle between the detection device and the trigger is adjusted according to the size of the second angle, so that the initial position of the bristles is at the preset stop position.
[0014] As a further improvement of the present invention, when the detection device detects that the triggering element triggers a stop signal, the side brush immediately stops rotating. At this time, the third angle between the detection device and the initial brush bristles is equal to the second angle.
[0015] As a further improvement of the present invention, when the detection device detects that the trigger element triggers a stop signal, the side brush rotates M fourth angles and then stops, where M is a positive integer and the fourth angle is 360° / N. When 1≤M<N, the third angle between the detection device and the initial brush bristles is equal to the sum of the second angle and M fourth angles; when M is equal to N or a multiple of N, the third angle between the detection device and the initial brush bristles is equal to the second angle; when M>N and M is not a multiple of N, the third angle between the detection device and the initial brush bristles is equal to the sum of the difference between M and N multiplied by the fourth angle and the second angle.
[0016] As a further improvement of the present invention, the method of triggering a stop signal by detecting the trigger element through the detection device when a preset stop condition is met includes:
[0017] The trigger is monitored in real time by the detection device. When a preset stop condition is met, a stop signal is sent through the detection device, or...
[0018] When the preset stop condition is met, the detection device starts to detect the trigger and triggers a stop signal.
[0019] As a further improvement of the present invention, the side-sweeping assembly includes a side-sweeping motor, and the method further includes:
[0020] The system receives a stop signal from the detection device and controls the side sweeper motor to stop rotating based on the stop signal.
[0021] The detection device sends a stop signal to the side sweeper motor to stop the side sweeper motor from rotating.
[0022] As a further improvement of the present invention, when the preset stop position changes, the initial stop position of the side brush is adjusted based on the changed preset stop position, wherein the method for adjusting the stop position of the side brush includes:
[0023] Adjust the size of the first angle between the trigger and the detection device, or,
[0024] Adjust the size of the second angle between the trigger and the initial bristles.
[0025] Another object of the present invention is to provide a side-scanning component that applies the above-described side-scanning stop method.
[0026] To achieve the above objectives, the present invention provides a side-sweeping assembly that applies the side-sweeping stop-and-go method of the above-described cleaning equipment, the side-sweeping assembly comprising:
[0027] A side brush consists of N bristles, where N ≥ 1. One of the bristles is defined as the initial bristle.
[0028] The trigger rotates synchronously with the side brush and has a preset second angle with the initial bristles.
[0029] A detection device is disposed on the movement path of the trigger and configured to detect the trigger and send a stop signal to stop the brush bristles from rotating at a predetermined position.
[0030] Another object of the present invention is to provide a cleaning device having the above-described side-sweeping assembly.
[0031] To achieve the above objectives, the present invention provides a cleaning device including the aforementioned side-sweeping assembly.
[0032] The beneficial effects of this invention are as follows: Compared with the prior art, the side-sweeping stop method of this invention determines the positional relationship between the brush bristles, the trigger, and the detection device by setting a preset stop position, so that the initial position of the brush bristles is at the preset stop position. When the preset stop condition is reached, the detection device detects the trigger to trigger a stop signal, thereby controlling the brush bristles to stop rotating at the specified stop position. The specified stop position is related to the preset stop position, so that the side brush on the side-sweeping assembly can stop rotating at the specified stop position according to the preset stop position, thereby effectively controlling the stop position of the side brush and avoiding the brush bristles from being deformed by pressure or damaged by the hair-cutting assembly.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0041] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0042] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0043] Please see Figure 1 and combined Figures 2 to 7 The image shows a preferred embodiment of the cleaning device's side-sweeping and stop method according to the present invention. This side-sweeping and stop method is applied to a cleaning device (not shown). The cleaning device is not limited to a specific type of device and can be a sweeping robot, a sweeping and mopping robot, a vacuum cleaner, or a floor scrubber, etc.
[0044] The cleaning equipment is equipped with a side sweeping component 100, which can control the stopping position of the side sweeping component 100 as needed, so that the side sweeping component 100 stops at the specified stopping position, avoiding the bristles 13 being squeezed or accidentally injured by the hair cutting component.
[0045] The cleaning equipment includes a machine body (not shown), a walking component (not shown) located below the machine body, a central sweeping component (not shown), and a side sweeping component 100.
[0046] The machine body includes a control unit (not shown) for controlling the movement and operation of the cleaning equipment. A walking assembly propels the cleaning equipment across the ground. Preferably, casters are also provided at the bottom of the machine body. A central sweeping assembly is located in the central area of the bottom of the machine body; optionally, the central sweeping assembly can be a roller brush structure.
[0047] The side sweeping component 100 is located at the bottom edge of the machine body and is connected to the control unit via a signal. The control unit can control the side sweeping component 100 to rotate along the rotating shaft 4. The rotating shaft 4 can be basically perpendicular to the ground, or the rotating shaft 4 can be at a certain angle relative to the ground, so as to better sweep debris and other materials to the roller brush area.
[0048] The side-sweeping assembly 100 includes a side brush 1, a trigger 2, a detection device 3, and a side-sweeping motor 6. The side-sweeping motor 6 drives the side brush 1 and the trigger 2 to rotate synchronously. The detection device 3 is configured to detect the trigger 2 and trigger a stop signal to stop the initial brush bristles 13 from rotating at a predetermined stop position.
[0049] Specifically, the side brush 1 is set on the rotating shaft 4 and includes N bristles 13, where N≥1, and one of the bristles 13 is defined as the initial bristle 13.
[0050] The trigger 2 rotates synchronously with the side brush 1. The trigger 2 has an extension axis L perpendicular to the rotation axis 4. The initial bristles 13 have a second angle with the extension axis L.
[0051] The detection device 3 is disposed on the movement path of the trigger 2 and has a first angle with the extension axis L. The detection device 3 is configured to detect the trigger 2 and send a stop signal to stop the initial bristles 13 from rotating at a predetermined stop position, wherein the predetermined stop position is related to the preset stop position.
[0052] The side-sweep and stop method includes the following steps:
[0053] S1: The control unit obtains the preset stop position of the side brush 1;
[0054] S2: The control unit determines the positional relationship between the initial brush bristles 13, the trigger 2, and the detection device 3 based on the preset stop position, so that the initial position of the side sweeping assembly 100 is at the preset stop position;
[0055] S3: When the preset stop condition is reached, the control unit detects the trigger 2 through the detection device 3 to trigger a stop signal and controls the brush bristles 13 to stop rotating at a specified stop position, wherein the specified stop position is related to the preset stop position.
[0056] This invention determines the positional relationship between the brush bristles 13, the trigger 2, and the detection device 3 based on the preset stop position by a control unit. This ensures that the initial position of the brush bristles 13 is at the preset stop position. When the preset stop condition is met, the detection device 3 detects the trigger 2 and triggers a stop signal, controlling the brush bristles 13 to stop rotating at a specified stop position. The specified stop position is related to the preset stop position, thereby effectively controlling the stop position of the side brush 1 through the control unit and preventing the brush bristles 13 from being deformed by pressure or damaged by the hair-cutting component.
[0057] Furthermore, the specified stop position is a preset stop position, or it can be a position formed by rotating M 360° / N positions beyond the preset stop position, where M is a positive integer. In other words, the specified stop position can be the same as or different from the preset stop position. For example, when the bristles 13 are irregularly arranged on the side brush 1, the control unit can control the bristles 13 to stop at the preset stop position using the aforementioned side-sweeping stop method. In this case, the specified stop position is the same as the preset stop position. When the bristles 13 are regularly arranged on the side brush 1, the control unit can control the bristles 13 to stop at the specified stop position using the aforementioned side-sweeping stop method. In this case, the specified stop position can be the same as or different from the preset stop position; for example, it can be a position formed by rotating M 360° / N positions beyond the preset stop position. This configuration provides multiple stop positions for the bristles 13.
[0058] Further, defining one of the bristles 13 as the initial bristle 13, the step S2, in which the control unit determines the positional relationship between the bristle 13, the trigger 2, and the detection device 3 based on a preset stop position, such that the initial position of the bristle 13 is at the preset stop position, includes:
[0059] The size of the first angle between the detection device 3 and the trigger 2 is determined, and the size of the second angle between the trigger 2 and the initial bristles 13 is adjusted according to the size of the first angle, so that the initial position of the bristles 13 is at the preset stop position, or...
[0060] The size of the second angle between the trigger 2 and the initial bristles 13 is determined, and the size of the first angle between the detection device 3 and the trigger 2 is adjusted according to the size of the second angle, so that the initial position of the bristles 13 is at the preset stop position.
[0061] In some embodiments, the size of the first angle between the detection device 3 and the trigger 2 is fixed. For example, when the detection device 3 is in a preset stop position, the first angle between the trigger 2 and the detection device 3 is set to 0°, and the second angle between the trigger 2 and the initial bristles 13 is adjusted. By adjusting the size of the second angle, the initial position of the bristles 13 is made to be in the preset stop position.
[0062] In some embodiments, the size of the second angle between the trigger 2 and the initial bristles 13 is determined. Moreover, at this time, the initial position of the side brush 1 cannot be set to the preset stop position by the second angle alone. In order to set the initial position of the side brush 1 to the preset stop position, it is necessary to adjust the installation position of the detection device 3 so that there is a first angle between the detection device 3 and the trigger 2, so that the initial position of the side brush 1 is set to the preset stop position by the sum of the first angle and the second angle.
[0063] In some embodiments, the side-sweeping stop method further includes: the control unit controlling the trigger 2 to rotate synchronously with the side brush 1. This configuration ensures that the second angle between the trigger 2 and the initial brush bristles 13 remains constant, thereby facilitating the determination of the angle between the trigger 2 and the detection device 3, and thus facilitating the installation of the detection device 3 in a suitable position.
[0064] In some embodiments, when the control unit detects the trigger 2 through the detection device 3 to trigger a stop signal, that is, the control unit sends a stop signal to the side sweeping motor 6 of the side sweeping assembly 100. Upon receiving the stop signal, the side sweeping motor 6 stops rotating, thereby controlling the side brush 1 to immediately stop rotating. At this time, the third angle between the detection device 3 and the initial brush bristles 13 is equal to the second angle. That is, the first angle between the detection device 3 and the trigger 2 is 0, meaning the extension axis L of the detection device 3 and the trigger 2 coincides. The third angle between the detection device 3 and the initial brush bristles 13 is equal to the second angle between the trigger 2 and the initial brush bristles 13. Furthermore, the predetermined stop position is a preset stop position. Of course, in other embodiments, the detection device 3 may also send a stop signal to the side sweeping motor 6 of the side sweeping assembly 100; this invention does not limit this.
[0065] In some embodiments, the control unit detects the trigger 2 through the detection device 3. The detection device 3 sends a detection signal to the control unit, which then sends a stop signal to the side sweeping motor 6. Upon receiving the stop signal, the side sweeping motor 6 does not immediately stop the side brush 1 from rotating, but continues to rotate for M fourth angles before stopping, where M is a positive integer and the fourth angle is 360° / N. In this case, the third angle between the detection device 3 and the initial brush bristles 13 is related to the value of M. Of course, in other embodiments, the detection device 3 may directly send a stop signal to the side sweeping motor 6 of the side sweeping assembly 100 after detecting the trigger 2, without transmitting it through the control unit. This invention does not limit this.
[0066] When 1 ≤ M < N, the third angle between the detection device 3 and the initial bristles 13 is equal to the sum of the second angle and M fourth angles. In this case, the specified stopping position is based on a preset stopping position and then rotated M times 360° / N, where M is a positive integer.
[0067] When M equals N or is a multiple of N, the third angle between the detection device 3 and the initial bristles 13 is equal to the second angle. At this time, the specified stop position is the preset stop position.
[0068] When M > N and M is not a multiple of N, the third angle between the detection device 3 and the initial bristles 13 is equal to the sum of the difference between M and N multiplied by the fourth angle and the second angle, i.e., the third angle = (MN) * the fourth angle + the second angle. In this case, the specified stopping position is defined as rotating M times 360° / N from the preset stopping position, where M is a positive integer.
[0069] In some embodiments, the detection device 3 is disposed on the movement path of the trigger 2. The trigger 2 contacts the detection device 3 each time it rotates. The control unit controls the detection device 3 to detect the trigger 2 in real time. When a preset stop condition is reached, the detection device 3 triggers a stop signal. That is, although the detection device 3 detects the trigger 2 in real time, it only triggers a stop signal when the preset stop condition is reached. If the preset stop condition is not reached, the detection device does not trigger a stop signal to avoid generating false trigger signals, which would cause the side brush 1 of the side sweeping assembly 100 to stop once in each rotation cycle, affecting the cleaning effect of the cleaning equipment.
[0070] In some embodiments, the detection device 3 is positioned on the movement path of the trigger 2. The trigger 2 contacts the detection device 3 each time it rotates. Only when a preset stop condition is met does the control unit control the detection device 3 to begin detecting the trigger 2 and trigger a stop signal. That is, if the preset stop condition is not met, the detection device 3 does not detect the trigger 2 or send a stop signal to avoid accidental triggering, which would cause the side brush 1 of the side-sweeping assembly 100 to stop once in each rotation cycle, affecting the cleaning effect of the cleaning equipment. Simultaneously, this also reduces the power consumption of the detection device 3.
[0071] It should be noted that the preset stop condition can be set as needed. For example, to prevent the hair-cutting component on the base station from accidentally damaging the bristles 13 or to prevent the structural ribs of the base station from squeezing the bristles 13, the preset stop condition can be that the cleaning equipment is properly parked in its parking position on the base station. Other preset stop conditions can also be set to stop the side-sweeping component 100 from working, and the present invention does not limit this.
[0072] In some embodiments, the cleaning device includes a control unit, and the side-sweeping assembly 100 includes a side-sweeping motor 6. The control unit is signal-connected to both the detection device 3 and the side-sweeping motor 6. The detection device 3 sends a stop signal to the control unit, and the control unit controls the side-sweeping motor 6 to stop rotating. That is, the stop signal from the detection device 3 is sent to the control unit, which then controls the side-sweeping motor 6 to stop rotating, thereby stopping the side brush 1 at a predetermined stop position. By controlling the operation of the side-sweeping motor 6, the control unit can uniformly allocate whether the side-sweeping motor 6 needs to be stopped, thus preventing the detection device 3 from sending false trigger signals.
[0073] In some embodiments, the side-sweeping assembly 100 includes a side-sweeping motor 6, and the detection device 3 is signal-connected to the side-sweeping motor 6. The detection device 3 sends a stop signal to the side-sweeping motor 6 to stop its rotation. That is, the stop signal from the detection device 3 is sent directly to the side-sweeping motor 6, and the detection device 3 controls the side-sweeping motor 6 to stop rotating, thereby reducing the power consumption of the control unit in the cleaning equipment.
[0074] When the preset stop position changes, the size of the second angle between the trigger 2 and the initial bristles 13 is adjusted so that the initial stop position of the side brush 1 is the preset stop position; or, the size of the first angle between the trigger 2 and the detection device 3 is adjusted so that the initial stop position of the side brush 1 is the preset stop position. Since the preset stop position is related to the positional relationship between the trigger 2, the initial bristles 13, and the detection device 3, by setting the positional relationship (i.e., the angular relationship) between the three, the initial stop position of the side brush 1 can be made to be the preset stop position.
[0075] To clearly illustrate this side-sweeping stopping method, the following example uses a side brush 1 with three bristles 13 and an angle of 120° between adjacent bristles 13. However, those skilled in the art will know that the side brush 1 of the side-sweeping assembly 100 is not limited to three bristles 13, nor is the angle between adjacent bristles 13 limited to 120°.
[0076] In this embodiment, the side brush 1 has a preset stop position. The first angle between the detection device 3 and the trigger 2 is set to 0°, and the second angle between the trigger 2 and the initial bristles 13 is set to 60°. At this point, the initial position of the three bristles 13 is the preset stop position. At this position, none of the three bristles 13 will be accidentally damaged by the hair-cutting component or come into contact with the structural ribs on the base station, thus preventing the side brush 1 from being deformed by pressure. Then, the side sweeping motor 6 operates, driving the trigger 2 and the side brush 1 to rotate synchronously via the rotating shaft 4. In this embodiment, the preset stop condition is that the cleaning equipment is properly parked in the parking position of the base station. When this preset stop condition is met, the control unit controls the detection device 3 to start detecting the trigger 2 and sends a stop signal to the control unit. The control unit controls the side sweeping motor 6 to stop rotating immediately. At this time, the extension axis L of the detection device 3 and the trigger 2 coincides. At this time, the third angle between the detection device 3 and the initial bristles 13 is equal to the second angle between the trigger 2 and the initial bristles 13. And at this time, the specified stop position is the preset stop position.
[0077] In another embodiment, when the preset stop condition is met, the control unit controls the detection device 3 to start detecting the trigger 2 and sends a stop signal to the control unit. The control unit controls the side sweeping motor 6 to stop rotating. After receiving the stop signal, the side sweeping motor 6 of the side sweeping assembly 100 does not control the side brush 1 to stop rotating immediately, but continues to rotate for M fourth angles before stopping. M is a positive integer, and the fourth angle is 360° / N. At this time, the third angle between the detection device 3 and the initial brush bristles 13 is related to the size of M.
[0078] When 1 ≤ M < N, for example, when N is 3 and M equals 2, the third angle between the detection device 3 and the initial brush bristles 13 is equal to the sum of the second angle and two fourth angles. At this time, the specified stop position is two 120° rotations based on the preset stop position. Since the initial brush bristles 13 are located at the preset stop position (to avoid accidental damage from the cutting component or contact with the structural ribs on the base station, which would cause the side brush 1 to be deformed by pressure), after the initial brush bristles 13 continue to rotate 240 degrees, the three brush bristles 13 are still in a state of avoiding accidental damage from the cutting component or contact with the structural ribs on the base station, which would cause the side brush 1 to be deformed by pressure.
[0079] Similarly, when M equals N or a multiple of N, for example, when M = N = 3, the specified stopping position is three 120° rotations from the preset stopping position, i.e., returning to the preset stopping position. At this time, the third angle between the detection device 3 and the initial bristles 13 is equal to the second angle.
[0080] When M > N and M is not a multiple of N, for example, when M = 5, the third angle between the detection device 3 and the initial brush bristles 13 is equal to the sum of 2 multiplied by the fourth angle and the second angle, that is, the third angle = (5-3) * the fourth angle + the second angle. At this time, the specified stopping position is to rotate 5 times 120° based on the preset stopping position, that is, the side brush 1 rotates 1 revolution and then rotates 2 times 120°. At this time, since the initial brush bristles 13 are located at the preset stopping position (so as to avoid being accidentally damaged by the cutting component or contacted by the structural ribs on the base station, thereby causing the side brush 1 to be deformed by pressure), when the initial brush bristles 13 continue to rotate 240 degrees, the three brush bristles 13 are still in a state of avoiding being accidentally damaged by the cutting component or contacted by the structural ribs on the base station, thereby causing the side brush 1 to be deformed by pressure.
[0081] In other embodiments, the N bristles 13 of the side brush 1 may also be non-uniformly arranged. For example, the side brush 1 may include two bristles 13, with angles of 80° and 280° between them, and either bristle 13 is defined as the initial bristle 13. It should be noted that the side brush 1 may also include three or more bristles 13, which may be non-uniformly arranged.
[0082] In this embodiment, when the preset stop condition is met, the control unit detects the trigger 2 via the detection device 3 and triggers a stop signal. Upon receiving the stop signal, the side-sweeping motor 6 of the side-sweeping assembly 100 controls the side brush 1 to immediately stop rotating. At this time, the detection device 3 coincides with the extension axis L of the trigger 2. At this time, the third angle between the detection device 3 and the initial bristles 13 is equal to the second angle between the trigger 2 and the initial bristles 13. Furthermore, at this time, the predetermined stop position is the preset stop position.
[0083] In other words, when the N bristles 13 of the side brush 1 are not uniformly arranged, when the preset stopping condition is reached, the control unit detects the trigger 2 through the detection device 3 and triggers a stop signal. After receiving the stop signal, the side brush motor 6 of the side brush assembly 100 needs to control the side brush 1 to stop rotating immediately. That is, the specified stopping position of the bristles 13 is the preset stopping position. Only in this way can it be ensured that each time the side brush 1 stops, the bristles 13 are in a state that avoids being accidentally damaged by the cutting component or contacted by the structural ribs on the base station, thus preventing the side brush 1 from being deformed by pressure.
[0084] It should be noted that in other embodiments, the control unit can control the detection device 3 to detect the trigger 2 in real time, and the detection device 3 will send a stop signal only when a preset stop condition is met. Alternatively, the detection device 3 can directly send a stop signal to the side sweeper motor 6, thereby controlling the side sweeper motor 6 to stop rotating. This invention does not limit this approach.
[0085] Please see Figures 2 to 7 and combined Figure 1 As shown, the present invention further provides a side-sweeping assembly 100, which applies the above-described side-sweeping stop method to control the stopping position of the bristles 13 of the side brush 1.
[0086] The side-sweeping assembly 100 includes a side brush 1, a trigger 2, a detection device 3, and a side-sweeping motor 6. The side-sweeping motor 6 drives the side brush 1 and the trigger 2 to rotate synchronously. The detection device 3 is configured to detect the trigger 2 and send a stop signal, causing the initial brush bristles 13 to stop rotating at a predetermined stop position.
[0087] Specifically, the side brush 1 is set on the rotating shaft 4 and includes N bristles 13, where N≥1, and one of the bristles 13 is defined as the initial bristle 13;
[0088] The trigger 2 rotates synchronously with the side brush 1. The trigger 2 has an extension axis L perpendicular to the rotation axis 4. The initial bristles 13 have a second angle with the extension axis L.
[0089] The detection device 3 is disposed on the movement path of the trigger 2 and has a first angle with the extension axis L. The detection device 3 is configured to detect the trigger 2 and thereby trigger a stop signal to stop the initial bristles 13 from rotating at a predetermined stop position, wherein the predetermined stop position is related to the preset stop position.
[0090] Furthermore, the specified stop position is a preset stop position, or the specified stop position is a rotation of M 360° / N based on the preset stop position, where M is a positive integer. That is, the specified stop position does not have to coincide with the preset stop position, as long as the brush bristles 13 are just in a state that avoids being accidentally damaged by the cutting component or contacted by the structural ribs on the base station, thereby preventing the side brush 1 from being deformed by pressure.
[0091] Furthermore, the sum of the first angle and the second angle is greater than 0° and less than 360° / N. For example, let's take a side brush 1 having 3 bristles 13 and an angle of 120° between adjacent bristles 13 as an example. However, those skilled in the art will know that the side brush 1 of the side brush assembly 100 is not limited to 3 bristles 13, and the angle between adjacent bristles 13 is not limited to 120°.
[0092] In this embodiment, the control unit obtains the preset stop position of the side brush 1, and sets the first angle between the detection device 3 and the trigger 2 to 0°, and the second angle between the trigger 2 and the initial bristles 13 to 60°. At this time, the initial position of the three bristles 13 is the preset stop position. At this position, none of the three bristles 13 will be accidentally damaged by the hair-cutting component, or come into contact with the structural ribs on the base station, thereby causing the side brush 1 to be deformed by pressure.
[0093] In some embodiments, the rotating shaft 4 is fixedly connected to the trigger 2. (See also...) Figures 2 to 7 As shown, in this embodiment, the side-sweeping assembly 100 includes a side brush 1, a trigger 2, a detection device 3, and a side-sweeping motor 6. The side-sweeping motor 6 drives the side brush 1 and the trigger 2 to rotate synchronously. The detection device 3 is configured to detect the trigger 2 and send a stop signal, causing the initial brush bristles 13 to stop rotating at a predetermined stop position.
[0094] The side brush 1 and the trigger 2 are respectively disposed on both sides of the rotating shaft 4. The side brush 1 includes a mounting base 11 and three side brush supports 12 disposed on the mounting base 11. Each side brush support 12 has a bristle 13 on the side away from the mounting base 11, that is, the mounting base 11 has three bristles 13, and the angle between adjacent bristles 13 is 120°. The bristle 13 with the smallest angle to the trigger 2 and closest to the detection device 3 is defined as the initial bristle 13.
[0095] The mounting base 11 has a mounting groove 111 on its inner side, and the rotating shaft 4 is fixed in the mounting groove 111. The rotating shaft 4 has a first positioning part 41 on the side near the side brush 1, and the side brush bracket 12 of the side brush 1 has a second positioning part 121 corresponding to the position of the first positioning part 41. The rotating shaft 4 and the side brush 1 are positioned and connected by the first positioning part 41 and the second positioning part 121. In this embodiment, the first positioning part 41 is a limiting groove 211 provided on the rotating shaft 4, and the second positioning part 121 is a limiting protrusion provided on the side brush 1. The limiting protrusion is engaged in the limiting groove 211 so that the rotating shaft 4 drives the side brush bracket 12 to rotate, thereby driving the bristles 13 to rotate.
[0096] The trigger 2 is located on the side of the rotating shaft 4 away from the bristles 13, and is driven by the rotating shaft 4 to rotate synchronously with the side brush 1. The trigger 2 is in the shape of a thin sheet, including a mounting part 21 and an extension part 22 extending from the mounting part 21 away from the mounting part 21. The extension part 22 has an extension axis L perpendicular to the rotating shaft 4. The extension part 22 contacts the detection device 3, thereby enabling the detection device 3 to detect the trigger 2.
[0097] The rotating shaft 4 has a limiting platform 42 on the side near the trigger 2. The trigger 2 has a limiting groove 211 corresponding to the limiting platform 42. That is, the limiting groove 211 is set on the mounting part 21, and the rotating shaft 4 and the trigger 2 are fixedly engaged by the limiting platform 42 and the limiting groove 211. That is, when the trigger 2 is installed on the rotating shaft 4, the second angle between the trigger 2 and the initial bristles 13 is fixed.
[0098] A limiting member 7 is also provided above the trigger member 2 to limit and fix the trigger member 2 in the vertical direction. In other embodiments, the trigger member 2 can also be fixed to the rotating shaft 4 by means of snap rings, screws, glue, etc.
[0099] Furthermore, a transmission gear 43 is provided on the rotating shaft 4. The transmission gear 43 is located between the side brush 1 and the trigger 2 and is connected to the motor of the side brush 1. The side brush 1 motor drives the rotating shaft 4 to rotate circumferentially.
[0100] Furthermore, the side-sweeping assembly 100 also includes a side-sweeping dental chamber 5, through which the rotating shaft 4 passes, and the trigger 2 is located inside the side-sweeping dental chamber 5. A detection device 3 is provided on the inner wall of the side-sweeping dental chamber 5, on the movement path of the trigger 2 and at a first angle with the extension axis L. The detection device 3 is configured to detect the trigger 2 and send a stop signal to stop the initial brush bristles 13 from rotating at a predetermined stop position, wherein the predetermined stop position is related to the preset stop position.
[0101] In this embodiment, the detection device 3 is a sensor, including two detection arms 31 arranged vertically, with a clearance portion 32 between the two detection arms 31, allowing the extension portion 22 of the trigger member 2 to pass through the detection device 3. When the extension portion 22 of the trigger member 2 is located in the clearance portion 32, the extension portion 22 blocks the signal transmission of the two detection arms 31, thereby enabling the detection device 3 to identify the trigger member 2. In other embodiments, the detection device 3 may also be a mechanical microswitch, or a photoelectric sensor, button, limit switch, etc. The present invention does not limit this.
[0102] In the above embodiment, the rotating shaft 4 and the trigger 2 are fixedly engaged by the limiting platform 42 and the limiting groove 211. At this time, when the trigger 2 is installed on the rotating shaft 4, the second angle between the trigger 2 and the initial bristles 13 is fixed.
[0103] If the initial position of the side brush 1 cannot be set to the preset stop position using only the second angle, the installation position of the detection device 3 needs to be adjusted to create a first angle between the detection device 3 and the trigger 2. The sum of the first and second angles will then ensure that the initial position of the side brush 1 is the preset stop position. Alternatively, another trigger 2 can be installed on the rotating shaft 4, such that the second angle between the trigger 2 and the initial bristles 13 precisely sets the initial position of the bristles 13 of the side brush 1 to the preset stop position.
[0104] When other situations arise, such as when the side-sweeping component 100 is moved to another cleaning device, or when the base station housing the side-sweeping component 100 changes, the preset stop position of the side-sweeping component 100 can be adjusted according to actual needs. When the preset stop position changes, the control unit can adjust the size of the first angle between the trigger 2 and the detection device 3 based on the changed stop position, or it can adjust the size of the second angle between the trigger 2 and the initial brush bristles 13 based on the changed stop position. Specifically, the size of the second angle between the trigger 2 and the initial brush bristles 13 can be adjusted by replacing the trigger 2, so that the initial stop position of the side brush 1 is the preset stop position; that is, the size of the second angle is adjusted by using a trigger 2 with a different angle from the initial brush bristles 13. Alternatively, there is a rotatable connection between the trigger 2 and the initial brush bristles 13 and the rotating shaft 4; by adjusting the installation position of the trigger 2 or the initial brush bristles 13, the size of the second angle between the trigger 2 and the initial brush bristles 13 can be adjusted. Alternatively, by adjusting the installation position of the detection device 3, the size of the first angle between the trigger 2 and the detection device 3 can be changed, thereby making the initial stop position of the side brush 1 the preset stop position.
[0105] In other embodiments, the rotating shaft 4 is circumferentially connected to the trigger 2. By allowing the trigger 2 to rotate circumferentially relative to the rotating shaft 4, the size of the second angle between the trigger 2 and the initial bristles 13 can be changed, thereby enabling one trigger 2 to adapt to multiple preset stop positions, or enabling the side-sweeping assembly 100 to adapt to different cleaning devices.
[0106] In one embodiment, a first gear (not shown) is provided on the side of the rotating shaft 4 near the trigger 2, and a second gear (not shown) is provided on the trigger 2 corresponding to the position of the first gear. The first gear and the second gear are meshed together, and the meshing force between the first gear and the second gear is greater than the centrifugal force of the rotating shaft 4. When an external force greater than the meshing force is applied to the trigger 2, the trigger 2 can rotate circumferentially relative to the rotating shaft 4 to change the size of the second angle between the trigger 2 and the initial bristles 13.
[0107] The rotating shaft 4 has a first engaging portion (not shown) on the side near the trigger 2. The trigger 2 has a second engaging portion (not shown) corresponding to the first engaging portion. One of the first engaging portion and the second engaging portion has a protrusion (not shown) evenly distributed circumferentially, and the other has a groove (not shown) corresponding to the protrusion. The first engaging portion and the second engaging portion are engaged by the protrusion and the groove. The engagement force between the protrusion and the groove is greater than the centrifugal force of the rotating shaft 4. When an external force greater than the engagement force is applied to the trigger 2, the trigger 2 can rotate circumferentially relative to the rotating shaft 4 to change the size of the second angle between the trigger 2 and the initial bristles 13.
[0108] In summary, the side brush stop method of the present invention adjusts the positional relationship between the brush bristles 13, the trigger 2, and the detection device 3 so that the initial position of the brush bristles 13 is at the preset stop position. When the preset stop condition is met, the detection device 3 detects the trigger 2 and sends a stop signal to control the brush bristles 13 to stop rotating at the specified stop position. The specified stop position is related to the preset stop position, thereby effectively controlling the stop position of the side brush 1 and preventing the brush bristles 13 from being deformed by pressure or damaged by the hair-cutting component.
[0109] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
