Description

Technical Field

[0001] The present invention relates to the field of floor scrubbers, and in particular provides a floor scrubber control method. Background Art

[0002] A floor scrubber is a cleaning machine designed to clean hard surfaces while simultaneously sucking up wastewater and removing it from the site. A floor scrubber primarily uses a roller brush to remove particles from the floor, dissolving them in water and sucking them into a wastewater tank. The greater the friction of the roller brush on the floor, the better the cleaning effect. While this pursuit of effective cleaning was accompanied by several user pain points, the user felt a sense of strain when holding the scrubber while turning, moving forward, and backward, making it difficult to use.

[0003] In order to solve the problem of difficulty in use, common floor scrubbers currently use forward and reverse power-assisted solutions. However, the floor scrubbers are laborious to turn. At the same time, when users hold the device to control the direction, there is a problem of inflexible left and right steering, and greater force and arm twisting angle are required to turn the cleaning body into place.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems and solve the problem that the existing floor scrubbers are not flexible in turning left and right and need to apply a large force and twist the arm angle to turn the cleaning body into place.

[0006] The present invention provides a control method for a floor scrubber, the floor scrubber comprising a handheld portion, a cleaning base, a steering mechanism, and a control portion; the handheld portion is provided with a steering trigger assembly, the steering mechanism is provided on the cleaning base, and the control portion is connected to both the steering trigger assembly and the steering mechanism. The control method comprises:

[0007] Acquire a first turn signal sent by the turn trigger component;

[0008] Based on the first turning signal, the turning mechanism is controlled to start operating so as to make the cleaning base turn.

[0009] When the above technical solution is adopted, when the cleaning base of the floor scrubber needs to be turned, the steering trigger component on the handheld part is pressed to obtain a first turning signal sent by the steering trigger component. The steering direction of the steering mechanism is controlled according to the first turning signal, so that the cleaning base can adjust its direction of travel under the action of the steering mechanism. This avoids the problem of the floor scrubber's inflexible left and right steering, which requires applying a large force and twisting the arm to turn the cleaning base into the correct direction.

[0010] In the specific implementation of the above floor washing machine control method, the step of "controlling the steering mechanism to start running based on the first steering signal" includes:

[0011] When the rising edge signal of the first steering signal is acquired, control the steering mechanism to start.

[0012] In the specific implementation of the above floor washing machine control method, the floor washing machine further includes a timing module. The step of "when the rising edge signal of the first steering signal is acquired, control the steering mechanism to start" further includes:

[0013] When the rising edge signal of the first steering signal is acquired, accumulate the delay duration. When the delay duration reaches the preset duration, then control the steering mechanism to start.

[0014] In the specific implementation of the above floor washing machine control method, the control method further includes:

[0015] If the delay duration does not reach the preset duration and the falling edge signal of the first steering signal is acquired, then control the steering mechanism not to start.

[0016] In the case of adopting the above technical solution, after delaying the preset duration, then control the steering mechanism to start. At the same time, if the falling edge signal of the first steering signal is acquired within the preset duration, then control the steering mechanism not to start, which can avoid the cleaning base turning due to accidental touch.

[0017] In the specific implementation of the above floor washing machine control method, the control method further includes:

[0018] If the delay duration does not reach the preset duration and the falling edge signal of the first steering signal is acquired, then control the delay duration to be cleared.

[0019] In the case of adopting the above technical solution, control the delay duration to be cleared. When the rising edge signal of the first steering signal is acquired again, start timing anew to ensure that the steering mechanism is started when the falling edge signal of the first steering signal is not received within the preset duration.

[0020] In the specific implementation of the above floor washing machine control method, the preset duration is any value between 0.2 seconds and 1 second.

[0021] In the specific implementation of the above floor washing machine control method, after the step of "controlling the steering mechanism to start running", the control method further includes:

[0022] If the falling edge signal of the first steering signal is acquired, or no signal is received, then control the steering mechanism to stop running or run in the reverse direction so that the cleaning base returns to the upright position.

[0023] In the case of adopting the above technical solution, if the falling edge signal of the first steering signal is obtained after the steering mechanism is started, the steering mechanism is controlled to run in the reverse direction or stop running, so as to realize the automatic alignment of the cleaning base. If no signal is received, it proves that the signal has been interrupted. At this time, the steering mechanism is also controlled to stop running or run in the reverse direction to realize the automatic alignment of the cleaning base.

[0024] In the specific implementation manner of the above floor washer control method, the control method further includes:

[0025] When the rising edge signal of the first steering signal is obtained, the steering mechanism is controlled to run at the first acceleration;

[0026] When the falling edge signal of the first steering signal is obtained, the steering mechanism is controlled to run at the second acceleration;

[0027] Wherein, the first acceleration is greater than the second acceleration.

[0028] In the case of adopting the above technical solution, when controlling the cleaning base to turn, the steering mechanism runs at a faster first acceleration to realize a faster turn of the cleaning base. When controlling the cleaning base to return to the original position, the steering mechanism runs at a slower second acceleration to realize a slow return of the cleaning base to the original position.

[0029] In the specific implementation manner of the above floor washer control method, after the step of "controlling the steering mechanism to start running", the control method further includes:

[0030] If the second steering signal of the steering trigger component is obtained, the steering mechanism is controlled to stop running or run in the reverse direction.

[0031] In the specific implementation manner of the above floor washer control method, the steering trigger component includes two steering buttons, and the two steering buttons are respectively located on both sides of the handheld part; or

[0032] The steering trigger component includes a steering slider, and the handheld part is provided with a chute, and the steering slider is slidably connected to the chute;

[0033] The steering trigger component further includes a contact, the contact is connected to the control part, and a trigger protrusion is arranged on the steering button or the steering slider. In the initial state, there is a gap between the contact and the trigger protrusion. Description of the Drawings

Detailed implementation manners

[0043] The preferred implementation manners of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present application and are not used to limit the protection scope of the present application. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios. For example, although the position sensor in the specification is described in combination with an infrared distance sensor, it is obvious that the present application can adopt other position sensors, such as an optical distance sensor, an ultrasonic distance sensor or a microswitch, etc.

[0044] It should be noted that in the description of this application, unless otherwise clearly specified and limited, terms such as "arrangement" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or other connections; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "inner" etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Additionally, "a plurality of" in this application means at least two.

[0045] As Figures 1-5 shown, to solve the problem that the existing floor washer is not flexible in turning left and right, and a large force and a large arm torsion angle are required to turn the cleaning main body in place, the present invention provides a floor washer, which includes a handheld part 1, a cleaning base 2, a steering mechanism and a control part; a steering trigger assembly is arranged on the handheld part 1, the steering mechanism is arranged on the cleaning base 2, and the control part is connected to both the steering trigger assembly and the steering mechanism.

[0046] In this way, when it is necessary to turn the cleaning base 2 of the floor washer, press the steering trigger assembly on the handheld part 1, the control part obtains the signal sent by the steering trigger assembly, and controls the steering direction of the steering mechanism according to the signal, so that the cleaning base 2 can adjust the traveling direction under the action of the steering mechanism. This avoids the problem that the existing floor washer is not flexible in turning left and right, and a large force and a large arm torsion angle are required to turn the cleaning base 2 in place.

[0047] In a preferred embodiment, the floor washer includes a handheld part 1, a cleaning base 2, a cleaning upper shell 3, a support assembly 6, a steering mechanism, a position sensor 9 and a control part. The steering mechanism further includes a driving mechanism, a driven mechanism and a connecting part 4.

[0048] See attached Figure 1, the lower end of the handheld part 1 is connected to the connecting part 4, and the upper end of the handheld part 1 is for the operator to hold. The steering trigger assembly is arranged near the position where the operator holds. The steering trigger assembly includes two steering buttons 11 and contacts. The two steering buttons 11 are respectively located on both sides of the handheld part 1. Trigger protrusions are arranged on the steering buttons 11. The contacts are connected to the control part. In the initial state, there is a gap between the contacts and the trigger protrusions. The two steering buttons 11 correspond to different steering directions of the floor washer. Using the steering buttons 11 for control operation is convenient. There is a gap between the contacts and the trigger protrusions. When the steering button 11 is pressed, the contacts and the trigger protrusions will not contact immediately, avoiding misoperation. For example, when the left (based on the position of the user) steering button 11 is pressed, after the steering button 11 is pressed for a certain stroke, the left trigger protrusion and the corresponding contact contact, and the control part receives the first steering signal of pressing the left steering button 11, and the control part controls the driving mechanism to rotate, so that the cleaning base 2 turns to the left.

[0049] Of course, the specific structural shape of the steering trigger assembly is not unique, and those skilled in the art can adjust it based on the specific scenario. For example, the steering trigger assembly includes a steering slider. The handheld part 1 is provided with a chute, and the steering slider is slidably connected to the chute. Trigger protrusions are arranged on the steering slider. The steering slider can move in the steering chute. When the steering slider is located at the first end of the chute, the trigger protrusion and the corresponding contact contact, and the control part receives the signal and controls the driving mechanism to rotate to realize the turning of the cleaning base 2. When the steering slider is located at the second end of the chute, the cleaning base 2 turns in the opposite direction. When the steering slider is located at the middle position in the length direction of the chute, the cleaning base 2 does not turn. The setting of the trigger protrusion and the contact is not necessary, and those skilled in the art can adjust it based on the specific scenario. For example, instead of using the trigger protrusion, the steering button 11 contacts the contact to realize the control of the commutation. Or a microswitch is used. The microswitch is connected to the control part. When the steering button 11 is pressed, the corresponding microswitch at the position is triggered.

[0050] See the appendix Figure 2 , placing recesses for placing the cleaning components are arranged on the front and rear sides of the cleaning base 2 (the forward direction is the front side of the cleaning base 2, and the backward direction is the rear side of the cleaning base 2). The cleaning components include two roller brushes 5 for cleaning the ground, and the roller brushes 5 are placed in the placing recesses.

[0051] See the appendix Figure 1 and 5, The cleaning upper shell 3 is buckled on the upper side of the cleaning base 2, and a cavity for installing the position sensor 9 is formed on the cleaning upper shell 3. Of course, the setting of the cleaning upper shell 3 is not necessary. Those skilled in the art can choose whether to set the cleaning upper shell 3 and its specific structure based on the specific application scenario. Of course, the cleaning upper shell 3 can also be not set. Of course, the specific structural shape of the cleaning component is not unique, and those skilled in the art can adjust it based on the specific scenario. For example, the cleaning component can be a disc-shaped cleaning brush. In addition, the specific structure and working principle of the rolling brush 5 are prior art and will not be elaborated here.

[0052] See appendix Figures 2-3 , The support component 6 includes two semi-circular support rings 61. Each support ring 61 extends downward to form support legs 62. The upper end of the support leg 62 is connected to the support ring 61, and the lower end of the support leg 62 is connected to the cleaning base 2. The two support rings 61 are butted and surrounded to form a circular cavity, and the connecting portion 4 passes through the circular cavity. An auxiliary rotating member is provided between the connecting portion 4 and the circular cavity. The auxiliary rotating member is preferably a ball bearing 43. The inner side of the ball bearing 43 is connected to the connecting portion 4, and the outer side of the ball bearing 43 is connected to the support ring 61. The ball bearing 43 enables relative rotation between the connecting portion 4 and the support ring 61.

[0053] Of course, the specific structural shape of the support component 6 is not unique, and those skilled in the art can adjust it based on the specific scenario. For example, a circular support ring 61 is adopted. Another example is that the support component 6 and the cleaning base 2 are integrally formed. Of course, the support component 6 can also be not set, so that the connecting portion 4 is directly connected to the cleaning upper shell 3. The setting of the auxiliary rotating member is not necessary. Those skilled in the art can choose whether to set the auxiliary rotating member and its specific structure based on the specific application scenario. The auxiliary rotating member can be a bushing, and of course, the auxiliary rotating member can also be not set.

[0054] See appendix Figure 3 and 4 , The driving mechanism is a driving motor 7, and the driven mechanism is a gear set. The gear set is preferably a helical gear set. A driving wheel 72 in the gear set is provided on the driving end of the driving motor 7, and the driving wheel 72 meshes with a driven gear ring 8 in the gear set. The driving motor 7 is connected to the cleaning base 2 through a driving connection seat 71. The driven gear ring 8 in the gear set is integrally formed with the connecting portion 4. After the driving motor 7 is started, it drives the driving wheel 72 to rotate and drives the connecting portion 4 to rotate, that is, the floor washer can be steered.

[0055] Of course, the specific configuration of the driving mechanism and the driven mechanism is not fixed. Without departing from the principles of the present application, those skilled in the art may adjust it so that the present application is applicable to more specific application scenarios. For example, the positions of the drive motor 7 and the gear set may be swapped or adjusted to other positions, such as by placing the drive motor 7 on the support assembly 6 via the drive connector 71. For another example, the gear set may be a spur gear set. For another example, the number of gears within the gear set may be single or multiple, and transmission is achieved through the meshing of multiple gears. For another example, a roller may be connected to the driving end of the drive motor 7, and the driven mechanism may be a rubber with high friction. The rubber is connected to the connecting portion 4, and the roller and the rubber are pressed tightly, so that the drive motor 7 drives the connecting portion 4 to rotate. For another example, the drive motor 7 may be arranged vertically, and a gear may be provided on the driving end of the drive motor 7. The lower end of the connecting portion 4 is provided with a tooth groove, and the gear and the tooth groove are meshed. For another example, the drive motor 7 may be arranged vertically, and a sprocket may be provided on the driving end of the drive motor 7. The lower end of the connecting portion 4 is also provided with a sprocket, and the two sprockets are connected by a chain drive. For another example, the driving motor 7 is vertically arranged, a pulley is provided on the driving end of the driving motor 7, and a pulley is also provided on the outer side of the lower end of the connecting part 4, and the two pulleys are connected by belt transmission.

[0056] See attached Figures 1-4 The connecting part 4 includes a first sleeve 41 and a second sleeve 42. The lower end of the first sleeve 41 is integrally provided with a driven gear ring 8. The first sleeve 41 passes through the circular cavity, and a ball bearing 43 is provided between the first sleeve 41 and the support ring 61; the inner side of the lower end of the second sleeve 42 is provided with a thread, and is threadedly connected to the upper end of the first sleeve 41. The upper end of the second sleeve 42 is connected to the lower end of the handheld part 1.

[0057] Of course, the setting of the connecting part 4 is not necessary. Those skilled in the art can select the specific structure of the connecting part 4 based on the specific application scenario. For example, the first sleeve 41 and the driven gear ring 8 are separately set and connected by threads; for another example, the second sleeve 42 passes through the circular cavity, and the outer side of the lower end of the second sleeve 42 is provided with a thread, and is threadedly connected to the first sleeve 41, etc.

[0058] See attached Figure 4 and 5, the position sensor 9 is installed in the cavity of the cleaning upper shell 3. A position identification block 63 is arranged outside the second sleeve 42. The position sensor 9 can detect the position of the position identification block 63, so as to detect whether the cleaning base 2 is aligned. When the cleaning base 2 is aligned, a vibration signal is sent outwards. Preferably, the position sensor 9 is an infrared distance sensor, and the position identification block 63 is a convex structure formed by the outward extension of the second sleeve 42. When the convex structure is located at the detection end of the infrared distance sensor, the detected distance by the infrared distance sensor becomes shorter, then it is determined that the cleaning base 2 has been aligned. Through the position sensor 9, it can be determined whether the cleaning base 2 is aligned, ensuring that the floor washer is in a forward driving state during normal operation.

[0059] It should be noted that the setting of the position sensor 9 is not necessary either. Those skilled in the art can choose whether to set the position sensor 9 and the specific structure of the position sensor 9 based on the specific application scenario. Of course, the position sensor 9 can also be an optical distance sensor, an ultrasonic distance sensor or a micro switch. The principles of the optical distance sensor and the ultrasonic distance sensor are similar to that of the infrared distance sensor, which will not be elaborated in this application. A micro switch is a switch that uses very little force. It is a switch in which an external mechanical force acts on the action reed through a transmission element, causing the fixed contact at its end to quickly connect or disconnect from the moving contact. The position identification block 63 can be used to trigger the micro switch. The specific way to send out the vibration signal can be to set a vibration motor in the handheld part. When the position sensor 9 detects that the cleaning base 2 is aligned, it sends a signal to the control part, and the control part controls the vibration motor to start.

[0060] The control part is installed on the cleaning base 2. The control part is used to receive signals and control the actions of relevant components. For example, when the control part receives the signal of the steering button 11, the control part controls the driving motor 7 to rotate, so that the cleaning base 2 changes direction. The specific selection of the control part is prior art and will not be elaborated here.

[0061] The following combines the attached Figures 6-7 , and introduces the control method of the floor washer of the present application.

[0062] As Figure 6 , corresponding to the above floor washer, the floor washer control method of the present application includes:

[0063] S101, obtain the first steering signal sent by the steering trigger component. For example, when the steering button is pressed, the trigger protrusion contacts the contact, so that the first steering signal can be obtained.

[0064] S103, based on the first steering signal, control the steering mechanism to start running so that the cleaning base turns. For example, analyze the different states of the first steering signal, and according to the different states of the first steering signal, control the driving motor to start, so that the cleaning base turns in different directions.

[0065] In the case of adopting the above technical solution, when it is necessary to turn the cleaning base of the floor washer, press the turning button on the handheld part, and the trigger protrusion contacts the contact point, so that a first turning signal can be obtained. According to the first turning signal, the driving motor is controlled to start, so that the cleaning base turns in different directions, and the cleaning base can adjust its traveling direction under the action of the driving motor. This avoids the problem that the floor washer is not flexible enough to turn left and right, and a large force and a large angle of arm torsion are required to turn the cleaning base in place.

[0066] The preferred embodiments of the present application will be introduced below.

[0067] First of all, it should be noted that the first turning signal is the signal sent during the process of pressing and releasing a turning button. The first turning signal includes a rising edge signal and a falling edge signal. Specifically, when the turning button is pressed and the trigger protrusion contacts the contact point, it is the rising edge signal of the first turning signal; when the pressed turning button is released and the trigger protrusion and the contact point are separated, it is the falling edge signal of the first turning signal. The second turning signal is the signal sent during the process of pressing and releasing another turning button.

[0068] In a preferred embodiment, the step of "controlling the steering mechanism to start and operate based on the first turning signal" includes:

[0069] When the rising edge signal of the first turning signal is obtained, the driving motor is controlled to start. For example, when the turning button is pressed and the trigger protrusion contacts the contact point, the rising edge signal of the first turning signal can be obtained, and then the driving motor is controlled to start to realize the turning of the cleaning base.

[0070] After the driving motor starts, if the falling edge signal of the first turning signal is obtained, the driving motor is controlled to run in reverse to make the cleaning base return to the original position. For example, when the pressed turning button is released and the trigger protrusion and the contact point are separated, the falling edge signal of the first turning signal can be obtained, and then the driving motor is controlled to start and run in reverse to realize the return of the cleaning base to the original position.

[0071] In this way, by one turning button, the control of turning and returning to the original position can be realized, and the operation is more convenient.

[0072] It should be noted that the above control method is not necessary, and those skilled in the art can select a specific control method based on the specific application scenario. For example, after the drive motor starts, if the falling edge signal of the first steering signal is obtained, the drive motor is controlled to stop running. At this time, the cleaning base stops rotating, and the user can manually return it to the original position. Or if there is a physical return structure such as a torsion spring, it can be automatically returned under the action of elastic force. Another example is that after the drive motor starts, if the second steering signal is obtained, the drive motor is controlled to stop running or run in the reverse direction.

[0073] In a preferred embodiment, the floor washer further includes a timing module. After the rising edge signal of the first steering signal is obtained, the timing module starts timing, and the timing duration of the timing module is the delay duration. The step of "controlling the steering mechanism to start when the rising edge signal of the first steering signal is obtained" further includes:

[0074] When the rising edge signal of the first steering signal is obtained, the delay duration is accumulated. When the delay duration reaches the preset duration, the drive motor is then controlled to start. In this way, when the rising edge signal of the first steering signal is obtained, the timing module is controlled to start timing, the delay duration is accumulated, and when the delay duration reaches the preset duration, the steering mechanism is then controlled to start, which can avoid the cleaning base from turning due to accidental touch. [[ID=【7】]] [[ID=【8】]]

[0075] It should be noted that the above control method is only preferred, and those skilled in the art can adjust it. For example, when the rising edge signal of the first steering signal is obtained, the drive motor is directly controlled to start. Correspondingly, the setting of the timing module is not necessary either, and those skilled in the art can choose not to set the timing module based on the specific application scenario.

[0076] Furthermore, if the delay duration has not reached the preset duration and the falling edge signal of the first steering signal is obtained, the drive motor is controlled not to start, and the delay duration is cleared; if the drive motor starts, the delay duration is cleared. When the rising edge signal of the first steering signal is obtained again, timing starts anew, ensuring that within the preset duration, the drive motor starts without receiving the falling edge signal of the first steering signal, thus avoiding turning due to accidental touch.

[0077] It should be noted that the above control method is only preferred, and those skilled in the art can adjust it. For example, if the falling edge signal of the first steering signal is obtained within the preset duration, the drive motor is controlled not to start, and the timing module pauses timing, and the delay duration remains unchanged. The preset duration is preferably 0.5 seconds, and those skilled in the art can adjust the preset duration based on the specific application scenario. For example, the preset duration can be 0.2 seconds, 0.6 seconds, or 1 second.

[0078] A preferred embodiment is that the control method further includes: when the rising edge signal of the first steering signal is obtained, controlling the driving motor to operate at a first acceleration; when the falling edge signal of the first steering signal is obtained, controlling the driving motor to operate at a second acceleration; wherein, the first acceleration is greater than the second acceleration. In this way, when controlling the cleaning base to turn, the driving motor operates at a faster first acceleration to achieve a faster turn of the cleaning base. When controlling the cleaning base to return to the original position, the driving motor operates at a slower second acceleration to achieve a slow return of the cleaning base.

[0079] It should be noted that the above control method is only preferred, and those skilled in the art can adjust it. For example, the first acceleration can be equal to the second acceleration. Another example is that the first acceleration is less than the second acceleration.

[0080] The following combines Figure 7 , and introduces a possible implementation process of the present application.

[0081] As Figure 7 shown, in a possible operation process:

[0082] S201, obtain the rising edge signal of the first steering signal;

[0083] S202, determine whether the delay duration ≥ the preset duration? If so, execute S203; otherwise, execute S204;

[0088] S207, control the steering mechanism to start in the reverse direction;

[0089] S208, obtain the return signal of the cleaning base;

[0090] S209, control the steering mechanism to stop.

[0091] It should be noted that although the detailed steps of the method of the present application are described in detail above, however, without departing from the basic principle of the present application, those skilled in the art can combine, split, and change the order of the above steps. In this way, the modified technical solution does not change the basic concept of the present application, and therefore also falls within the protection scope of the present application.

For example, in the claims of this application, any one of the claimed embodiments can be used in any combination.

[0093] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
