Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of cleaning equipment, and particularly relates to a dust cup dust compression mechanism, a control method thereof and a computer readable medium. BACKGROUND

[0002] A dust collector is a common cleaning equipment. During use, the dust collector sucks garbage into a dust cup, and performs primary separation through a metal screen in the dust cup, and stores the garbage in the dust cup. However, during long-time use or large-capacity garbage cleaning, a large amount of hair and dust will accumulate in the dust cup. After the dust cup of the existing dust collector is full, the garbage can only be emptied, which causes the user to need to empty the garbage frequently, resulting in poor user experience.

[0003] The information disclosed in this BACKGROUND section is only for the purpose of increasing the understanding of the background of the present disclosure and should not be regarded as an acknowledgment or any form of suggestion that it forms prior art of this disclosure. SUMMARY

[0004] The present disclosure aims to provide a control method of a dust cup dust compression mechanism, which can compress garbage in the dust cup, increase the garbage capacity of the dust cup, reduce the garbage emptying frequency, and improve user experience.

[0005] To achieve the above-mentioned purpose, a control method of a dust cup dust compression mechanism is provided in an embodiment of the present disclosure. The dust compression mechanism comprises a driving motor and a dust compression assembly in the dust cup. The control method comprises the following steps: the driving motor drives the dust compression assembly to perform a dust compression action in the dust cup, and detects the current value I1 of the driving motor in real time; when the current value I1 reaches the locked-rotor current value I2 of the driving motor, the current of the driving motor is increased until the current value I1 after the increase reaches a preset current value I3, wherein the preset current value I3 is greater than the locked-rotor current value I2; and the driving motor controls the dust compression assembly to stop the dust compression action.

[0006] An embodiment of the present disclosure further provides a dust cup dust compression mechanism, which is suitable for the above-mentioned control method. The dust compression mechanism comprises a dust compression assembly, a driving assembly, a control module and a detection unit. The dust compression assembly is installed in the dust cup. The driving assembly comprises a driving motor and a transmission structure. The transmission structure is drivingly connected between the driving motor and the dust compression assembly. The driving motor can drive the driving motor to move in the dust cup through the transmission structure to compress garbage in the dust cup. The control module is in communication connection with the driving motor to control the start and stop of the driving motor. The detection unit is in communication connection with the driving motor and the control module to detect the current value of the driving motor.

[0007] A specific embodiment of this disclosure also provides a computer-readable medium carrying computer-executable instructions, which, when executed by a processor, are used to implement the control logic of the control method for the dust cup ash-pressing mechanism described above.

[0008] Compared to existing technologies, the dust cup control method of this disclosure uses a dust-pressing mechanism to compress the dust within the dust cup by controlling the mechanism to perform a pressing action. This reduces voids, holes, or gaps between the dust particles, creating new space within the dust cup to accommodate more dust. This allows the vacuum cleaner to continue operating without the user needing to empty the dust cup, extending its continuous working time and improving the user experience. Furthermore, under the condition of a fixed drive motor, this control method can compress the dust more tightly, further increasing the dust cup's capacity. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0018] The dust cup mechanism of a conventional vacuum cleaner typically includes a dust cup and a filter (such as a metal filter) installed inside the dust cup. After debris enters the dust cup with the airflow, it is trapped inside by the filter, while the filtered airflow passes through the filter and flows to the vacuum cleaner's motor mechanism. The motor mechanism may include a drive motor and blades connected to the motor's rotating output. The drive motor drives the blades to rotate, generating negative pressure. This negative pressure forces the airflow and debris through the dust cup mechanism to the motor mechanism.

[0019] Since vacuum cleaners typically pick up mainly hair, dust, food scraps, and other debris, most of this debris is haphazardly placed in the dust cup. Especially when there's a lot of hair in the dust cup, it creates numerous cavities and / or holes within the dust. These cavities and / or holes only hold a small amount of debris, consisting mostly of air. This means that even a small amount of debris can quickly fill the dust cup (primarily the dust collection chamber) and clog or cover the filter surface. Although the dust cup may seem full, its actual capacity is limited, requiring frequent emptying, severely impacting the user experience.

[0020] The dust cup control method disclosed herein compresses the dust inside the dust cup by controlling the dust-pressing mechanism to perform a pressing action. This reduces the voids, holes, or gaps between the dust particles, creating new space inside the dust cup to accommodate more dust. This allows the user to continue using the vacuum cleaner without emptying the dust cup, extending the vacuum cleaner's continuous working time and improving the user experience.

[0021] like Figure 1 As shown, a control method for a dust cup ash-pressing mechanism according to an embodiment of this disclosure is provided. The ash-pressing mechanism includes a drive motor connected to it and an ash-pressing component located inside the dust cup. The control method includes the following steps:

[0022] S100: The drive motor drives the ash-pressing assembly to perform ash-pressing action in the dust cup, and the current value I1 of the drive motor is detected in real time.

[0023] S200. When the current value I1 reaches the stall current value I2 of the drive motor, the current of the drive motor is increased until the increased current value I1 reaches the preset current value I3, wherein the preset current value I3 is greater than the stall current value I2.

[0024] S300, drive motor controls the ash pressing component to stop the ash pressing action.

[0025] The core concept of the control method disclosed herein is to determine whether the ash-pressing mechanism has finished its ash-pressing action by detecting the current value of the drive motor. The stall current value I2 of the drive motor represents the current value corresponding to the drive motor when it is stalled, that is, the maximum current consumed when the motor cannot rotate or cannot work normally. When the current value I1 of the drive motor reaches the stall current value I2, it indicates that the drive motor is stalled, and the torque of the drive motor at this time is the stall torque. In order to make the space occupied by the compressed garbage in the dust cup smaller, that is, to make the garbage more compacted, in step S200, when the current value I1 reaches the stall current value I2 of the drive motor, the current of the drive motor is increased by utilizing the principle that the torque of the motor is proportional to the current, so that the torque of the drive motor continues to increase from the stall torque, thereby giving the ash-pressing component a greater thrust than when the drive motor is stalled, compressing the garbage in the dust cup more compactly, thereby further increasing the garbage capacity in the dust cup, extending the continuous working time of the vacuum cleaner, and reducing the number of times the garbage in the dust cup needs to be emptied.

[0026] Each step of the control method disclosed herein will be described in detail below.

[0027] Step S100: The drive motor drives the ash pressing component to perform ash pressing action in the dust cup, and the current value I1 of the drive motor is detected in real time.

[0028] The vacuum cleaner may also include a control module connected to the drive motor, which controls the start and stop of the drive motor, thereby achieving automated control of the entire dust-pressing process.

[0029] The ash-pressing component can be located inside the dust cup and can move within the dust cup under the drive of the drive motor, thereby compressing the waste inside the dust cup. The ash-pressing component and the drive motor can be connected through a transmission structure. When the ash-pressing component moves linearly along the axial direction of the dust cup, the transmission structure mainly converts the force of the drive motor's rotation into the force that drives the ash-pressing component to move linearly along the axial direction of the dust cup.

[0030] The dust collection component can have an initial position within the dust cup. Figure 2 The position of the medium-pressure ash component 13 is the initial position) and the position of maximum displacement ( Figure 3The position of the ash-pressing component 13 is the maximum displacement position. The ash-pressing action can be considered as the process of the drive motor driving the ash-pressing component to move from the initial position to the maximum displacement position within the dust cup; or, the process of the drive motor driving the ash-pressing component to move from any position between the initial position and the maximum displacement position within the dust cup to the maximum displacement position. The maximum displacement position can be considered as the final position that the ash-pressing component can move to when there is no waste or only a small amount of waste in the dust cup. The initial position can be considered as the position within the dust cup that is farthest from the maximum displacement position along its direction of movement. That is, when the ash-pressing component performs the ash-pressing action, it does not necessarily start moving from the initial position and terminate at the maximum displacement position. It can start moving from any position between the initial position and the maximum displacement position towards the maximum displacement position. As for when it terminates, it depends on the specific situation.

[0031] In a specific example, the dust cup has a dust collection chamber for holding waste. The dust collection chamber can be formed by the inner wall of the dust cup and a filter (and can also be formed by other mechanisms). The ash-pressing component is located inside the dust collection chamber and can move linearly along the axial direction of the dust collection chamber. When the dust collection chamber is vertically set, the axial direction of the dust collection chamber is vertical. Therefore, the top of the dust collection chamber can be considered as the initial position of the ash-pressing component, and the bottom of the dust collection chamber can be considered as the maximum displacement position of the ash-pressing component. The ash-pressing component moves from top to bottom inside the dust collection chamber, which is the ash-pressing action performed by the ash-pressing component. The ultimate goal is to press the waste in the dust collection chamber to the bottom of the dust collection chamber. When there is a lot of waste in the dust collection chamber, the ash-pressing component performs the ash-pressing action and presses the waste. Due to the large amount of waste, the pressed waste has a certain thickness, making it impossible for the ash-pressing component to reach the maximum displacement position. According to the subsequent steps S200 and S300, the ash-pressing component can complete the ash-pressing action. Therefore, the end of the ash-pressing action is not necessarily determined by the ash-pressing component moving to the maximum displacement position.

[0032] Preferably, before performing the ash-pressing action, the ash-pressing component is preferably in its initial position. The ash-pressing component can roughly divide the dust collection chamber into a first chamber and a second chamber. Along the movement direction of the ash-pressing component, the first chamber is located on the side of the ash-pressing component facing the maximum displacement position, while the second chamber is located on the side of the ash-pressing component facing away from the first chamber. Since the purpose of compressing waste is to compress the waste at the maximum displacement position in the dust collection chamber, that is, the waste in the first chamber can be compressed, the larger the first chamber is, the better, and the smaller the space of the second chamber is, the better.

[0033] When there is little or no garbage in the dust cup, if the ash pressing component performs the ash pressing action, the thickness of the compacted garbage is almost negligible. At this time, the ash pressing component has moved to the maximum displacement position. At this time, it is meaningless to execute the step S200 to increase the current of the drive motor. It will only do useless work.

[0034] The dust cup is equipped with a first sensing unit for detecting whether the ash-pressing component is at its maximum displacement position. The first sensing unit is located adjacent to or at the maximum displacement position of the ash-pressing component. The control method further includes: when the current value I1 reaches the stall current value I2 of the drive motor, and the first sensing unit does not sense the ash-pressing component, increasing the current of the drive motor.

[0035] The first sensing unit can communicate with the control module. Its main function is to detect whether the ash-pressing component is at its maximum displacement position. When the first sensing unit detects the ash-pressing component, it sends a signal to the control module, which then controls the drive motor based on this signal. If the first sensing unit does not detect the ash-pressing component, it indicates that the ash-pressing component has not reached its maximum displacement position. In this case, step S200 can further increase the current to the drive motor, thereby causing the drive motor to further drive the ash-pressing component to compact the waste.

[0036] Furthermore, the control method also includes: when the first sensing unit senses the ash-pressing component, the drive motor controls the ash-pressing component to stop the ash-pressing action. When the ash-pressing component moves to the maximum displacement position, it can no longer move, so the drive motor will stall, that is, the current value I1 reaches the stall current value I2 of the drive motor. The first sensing unit also senses that the ash-pressing component is at the maximum displacement position. In order to avoid subsequent wasted work, the drive unit can control the ash-pressing component to stop the ash-pressing action.

[0037] To facilitate continued vacuuming, when the first sensing unit detects the dust-pressing component, the drive motor controls the dust-pressing component to stop its pressing action and return it to its initial position. After the dust-pressing component returns to its initial position, the volume of the first space in the dust cup that can be compressed by the dust-pressing component is maximized, allowing it to continue to hold as much new debris as possible.

[0038] In this embodiment, the first sensing unit is a limit switch. When the ash-pressing component is at its maximum displacement position, it triggers the limit switch, generating a trigger signal which is then transmitted to the control module. Upon receiving the trigger signal, the control module confirms that the ash-pressing component is at its maximum displacement position. When the ash-pressing component moves away from its maximum displacement position, it stops triggering the limit switch, and the limit switch ceases generating trigger signals. Since the control module no longer receives trigger signals, it confirms that the ash-pressing component is not at its maximum displacement position. The limit switch can be a common push-button switch.

[0039] In other embodiments, the first sensing unit may also be a common sensor such as an infrared sensor, a pressure sensor, or a Hall sensor.

[0040] In one specific embodiment, the dust cup is provided with a second sensing unit for detecting whether the ash pressing component is in the initial position. The second sensing unit is located adjacent to the initial position of the ash pressing component, or the second sensing unit is located at the initial position of the ash pressing component. The control method further includes: when the second sensing unit senses the ash pressing component, the drive motor controls the ash pressing component to stop moving.

[0041] The second sensing unit is connected to the control module. The second sensing unit is mainly used to sense whether the ash pressing component is in the initial position. Its working principle can be referred to the first sensing unit, and will not be repeated here.

[0042] Specifically, the second sensing unit is a limit switch, which is triggered when the ash-pressing assembly is at its maximum displacement position. In this embodiment, the limit switch can be a common push-button switch. In other embodiments, the second sensing unit can also be a common sensor such as an infrared sensor, pressure sensor, or Hall effect sensor.

[0043] In one specific embodiment, the dust-pressing component is connected to the dust-scraping component, and the dust-scraping component abuts against the inner wall of the dust cup and / or the filter screen (also referred to as a filter) inside the dust cup. When the drive motor drives the dust-pressing component to perform the dust-pressing action inside the dust cup, the drive motor simultaneously drives the dust-scraping component to scrape the inner wall of the dust cup and / or the filter screen inside the dust cup. Therefore, in step S100, while the dust-pressing component is performing the dust-pressing process, the dust-scraping component also simultaneously scrapes the inner wall of the dust cup and / or the filter screen inside the dust cup, thus cleaning the inside of the dust cup.

[0044] S200. When the current value I1 reaches the stall current value I2 of the drive motor, the current of the drive motor is increased until the increased current value I1 reaches the preset current value I3, wherein the preset current value I3 is greater than the stall current value I2.

[0045] During the process of the drive motor driving the ash-pressing component to perform the ash-pressing action in the dust cup, the garbage in the dust cup will be gradually compacted, that is, the reaction force on the ash-pressing component will gradually increase. In order to compact the garbage, the control module will gradually increase the current of the drive motor based on the principle that the torque of the motor is proportional to the current, thereby generating a larger torque. This process is generally terminated when the drive motor reaches the stall state, that is, when the current value I1 reaches the stall current value I2 of the drive motor, this can be considered as the process of the garbage being compacted once.

[0046] The applicant discovered that when the drive motor reaches a stall state, the current of the drive motor can be increased for a short period of time, causing the torque of the drive motor to continue to increase from the stall torque. This results in the ash compaction component receiving greater thrust than when the drive motor is stalled, thus compressing the waste in the dust cup more tightly. Therefore, after the current value I1 reaches the stall current value I2 of the drive motor, the applicant increases the current of the drive motor to compact the waste. This process can be considered as a secondary compaction of the waste.

[0047] Furthermore, the applicant discovered that although the current of the drive motor could be further increased, excessively high current values ​​I1 and / or excessively long secondary compaction times could easily damage the drive motor. Therefore, the secondary compaction time—the time between the current value I1 reaching the stall current value I2 of the drive motor and the subsequent current increase until the drive motor controls the ash-pressing component to stop the ash-pressing action—should be controlled within 1 second, especially within 0.5 seconds. The applicant also set a preset current value I3 to prevent excessively high current values ​​I1. The specific value of the preset current value I3 can be determined based on the parameters of the drive motor, but it must be less than or equal to 120% of the stall current value I2. For example, if the stall current value I2 of the drive motor is 10A, then the preset current value I3 can be set to 10.5A, 11A, 11.6A, 12A, etc., with a maximum of 12A.

[0048] In this embodiment, the step of increasing the current of the drive motor includes: increasing the voltage of the drive motor to increase the current of the drive motor. Specifically, the control module may include a PWM module, that is, the voltage of the drive motor is regulated by using a PWM signal.

[0049] Since this disclosure increases the current by increasing the voltage, in actual operation, there may be a situation where the increased current value I1 does not reach the preset current value I3 after increasing the voltage. Therefore, the step of increasing the current of the drive motor in step S200 until the increased current value I1 reaches the preset current value I3 specifically includes:

[0050] Increase the voltage of the drive motor and determine whether the increased current value I1 reaches the preset current value I3;

[0051] If so, then stop increasing the voltage of the drive motor;

[0052] If not, continue to increase the voltage of the drive motor and re-evaluate whether the increased current value I1 reaches the preset current value I3, until the current value I1 reaches the preset current value I3.

[0053] The core idea of ​​the above steps is as follows: Each time, a fixed voltage value U1 is added, and then it is determined whether the increased current value I1 reaches the preset current value I3. If not, a fixed voltage value U1 is added again until the increased current value I1 reaches the preset current value I3, thus proceeding to the next steps. The increased current value I1 reaching the preset current value I3 means that the increased current value I1 is equal to or slightly greater than the preset current value I3.

[0054] In a specific example, the stall current value I2 of the drive motor is 10A, the preset current value I3 is 12A, and the voltage U1 is 10V each time. When the current value I1 reaches the stall current value I2, the control module adds 10V to the drive motor, and the boosted current value I1 is 10.6A. Then, the voltage is increased by 10V until the boosted current value I1 reaches or exceeds 12A.

[0055] S300, drive motor controls the ash pressing component to stop the ash pressing action.

[0056] In step S300, after the drive motor controls the ash-pressing component to stop the ash-pressing action, the drive motor controls the ash-pressing component to move to the initial position. If the ash-pressing action of the drive motor controlling the ash-pressing component is considered to be achieved by the forward rotation of the drive motor, then the movement of the drive motor controlling the ash-pressing component to the initial position is achieved by the reverse rotation of the drive motor.

[0057] Figure 2 This is a detailed logic block diagram of the control method for the dust cup's ash-pressing mechanism in a specific application scenario, where there is no first sensing unit. Figure 2 The logic block diagram shown clearly illustrates the specific control logic of the control method disclosed herein.

[0058] like Figure 3 As shown, in another specific embodiment, the control method for the dust cup ash-pressing mechanism of this disclosure further includes:

[0059] S400. After the drive motor controls the ash pressing component to stop the ash pressing action, perform the ash pressing action again.

[0060] The step of performing the ash-pressing action again includes: driving the motor to reverse for a preset time, and then driving the motor to rotate forward to control the ash-pressing component to perform the ash-pressing action.

[0061] Step S300 can be considered the first ash-pressing action, and step S400 is the second ash-pressing action after step S300. The preset time can be 0.5s, 1s, etc., and can also be adjusted according to actual needs. The reverse rotation of the drive motor is mainly to move the ash-pressing component away from the compacted waste in the dust cup after the first ash-pressing action. Then, the drive motor rotates forward to control the ash-pressing component to perform the ash-pressing action. This process can ensure the degree of compaction of the waste and prevent some waste from being adsorbed onto the ash-pressing component under the action of electrostatic forces after the first ash-pressing action.

[0062] In addition, in the above description, the default forward rotation of the drive motor is to drive the ash pressing component to perform the ash pressing action, that is, the forward rotation of the drive motor can drive the ash pressing component to move to the maximum displacement position.

[0063] like Figure 4 and Figure 5 As shown in a specific embodiment, this disclosure also provides a dust cup pressing mechanism, applicable to the above-described control method. The pressing mechanism 1 includes a pressing component 11, a drive component 12, a control module, and a detection unit. The pressing component 11 is installed inside the dust cup 2. The drive component 12 includes a drive motor 121 and a transmission structure 122. The transmission structure 122 is connected between the drive motor 121 and the pressing component 11. The drive motor 121 can be driven to move inside the dust cup 2 through the transmission structure 122 to compress the waste inside the dust cup 2. The control module is communicatively connected to the drive motor 121 to control the start and stop of the drive motor 121. The detection unit is communicatively connected to the drive motor 121 and the control module to detect the current value of the drive motor 121.

[0064] The dust-pressing assembly 11 is installed inside the dust collection chamber 21 of the dust cup 2. The dust-pressing assembly 11 may include a pressure plate, and the dust-pressing mechanism 1 also includes a dust-scraping assembly 13 installed on the pressure plate. In this embodiment, the dust-scraping assembly 13 includes at least one scraping element, which can abut against the filter 3 (filter screen) and / or the inner wall of the dust cup 2. When the dust-pressing assembly 11 is moving, the scraping element simultaneously scrapes against the filter 3 (filter screen) and / or the inner wall of the dust cup 2. The filter 3 is arranged around the dust cup 2, and the pressure plate can be sleeved around the filter 3.

[0065] The transmission structure 122 can be a lead screw structure, which converts the rotational force output by the drive motor 121 into a force that drives the ash-pressing assembly 11 to move linearly. The lead screw structure can include a threaded seat and a lead screw. The threaded seat can be connected to the ash-pressing assembly 11 through a connecting rod, and the lead screw is connected to the output end of the drive motor 121.

[0066] The control module is a common controller on the market, such as a PLD (Programmable Logic Device), which can be set up independently and communicate with the vacuum cleaner's controller, or it can be part of the vacuum cleaner's controller.

[0067] The detection unit (not shown in the figure) is a conventional circuit module for detecting current, used to detect the circuit of the drive motor 121.
