Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, and specifically provides a floor scrubber. Background Art

[0002] A floor scrubber is a cleaning machine that is suitable for cleaning hard floors and sucking out wastewater at the same time, and taking the wastewater away from the site. The floor scrubber mainly uses a roller brush to clean the particles on the ground, and then dissolves the particles in water and sucks them into the sewage tank. The greater the friction of the roller brush on the ground, the better the cleaning effect. Of course, on the basis of pursuing the cleaning effect, there are also the following pain points in use: users holding the floor scrubber can easily feel strenuous when turning, moving forward, and moving backward, which is inconvenient to use.

[0003] In order to solve the problem of difficulty in use, the current common floor scrubbers adopt forward, reverse and steering assistance solutions, but the control of the steering angle usually adopts physical blocking. The steering drive cannot be powered off in time after the steering is completed, which can easily cause the steering drive to be overloaded and damaged. Utility Model Content

[0004] The utility model aims to solve the above technical problems and solve the problem that the existing floor scrubber cannot cut off the power of the steering drive in time after the steering is completed, which easily causes the steering drive to be overloaded and damaged.

[0005] The utility model provides a floor scrubber, comprising a cleaning body, a steering mechanism, a position detection mechanism and a handheld part;

[0006] The steering mechanism is connected to the cleaning body, and is configured to drive the cleaning body to turn; a position detection mechanism is provided on one of the steering mechanism and the cleaning body, and a position identification portion is provided on the other, and the position detection mechanism is configured to send a signal to the outside when the cleaning body rotates to the point where the position detection mechanism corresponds to the position identification portion;

[0007] The hand-held part is rotatably connected to the cleaning body.

[0008] In the case of adopting the above technical solution, the steering mechanism can drive the cleaning body to turn, and the position detection mechanism and the position identification part can send out a signal when they correspond, so that the steering mechanism can stop driving or reverse driving after the cleaning body turns to the set position, avoiding the failure to cut off the power of the steering mechanism in time after the turning is completed, causing overload damage to the steering mechanism. For example, when the cleaning body needs to turn, the steering mechanism controls the cleaning body to turn relative to the handheld part, and the position detection mechanism can detect the steering angle of the cleaning body relative to the handheld part. When the preset angle is reached, the steering mechanism can be controlled to close, so that the cleaning body can be at this angle for a long time, avoiding overload damage to the steering mechanism.

[0009] In a specific embodiment of the above-mentioned floor scrubber, the position detection mechanism includes at least one position sensor, and the position sensor is arranged on the cleaning body.

[0010] In a specific embodiment of the above-mentioned floor scrubber, the cleaning body includes a cleaning base and a cleaning upper shell, the cleaning upper shell is connected to the cleaning base, and the position sensor is connected to the cleaning upper shell.

[0011] In a specific embodiment of the above-mentioned floor scrubber, the position sensor is an infrared distance sensor, an optical distance sensor, an ultrasonic distance sensor or a micro switch.

[0012] In a specific embodiment of the above-mentioned floor scrubber, the steering mechanism includes a connecting part, a driving mechanism and a driven mechanism, one end of the connecting part is connected to the hand-held part, and the other end of the connecting part is rotatably connected to the cleaning body, one of the connecting part and the cleaning body is provided with the driving mechanism, and the other is provided with the driven mechanism, and the driving mechanism is cooperatively connected with the driven mechanism.

[0013] When the above technical solution is adopted, the hand-held part and the cleaning body can be connected through the connecting part, and the moving direction of the cleaning body can be controlled through the cooperation between the driving mechanism and the driven mechanism.

[0014] In a specific embodiment of the above-mentioned floor scrubber, the position identification portion is arranged on the connecting portion.

[0015] In a specific embodiment of the above-mentioned floor scrubber, the position identification portion is a raised structure.

[0016] When the above technical solution is adopted, the protruding structure can be easily detected by the position sensor.

[0017] In a specific embodiment of the above-mentioned floor scrubber, the number of the position sensor is one, the number of the protrusion structures is three, and the three protrusion structures are arranged at intervals along the circumferential direction of the connecting portion, wherein the protrusion structure located in the middle is arranged to be opposite to the position sensor when the cleaning body is in the return position, and the protrusion structures located on both sides are arranged to be opposite to the position sensor when the cleaning body is in the forward rotation limit position and the reverse rotation limit position.

[0018] In the case of adopting the above technical solution, three protrusion structures and one position sensor are used, so that the position sensor can send signals when the cleaning body is at the return position, the forward rotation limit position, and the reverse rotation limit position. For example, when the cleaning body is at the forward rotation limit position, the position sensor detects the protrusion structure and sends a signal, so that the steering mechanism stops driving the cleaning body to rotate, avoiding long-term overload and damage to the steering mechanism.

[0020] In the case of adopting the above technical solution, a protruding structure and three position sensors are used, so that the position sensors can send signals when the cleaning body is at the return position, the forward rotation limit position, and the reverse rotation limit position. For example, when the cleaning body is at the forward rotation limit position, the position sensor detects the protruding structure and sends a signal, so that the steering mechanism stops driving the cleaning body to rotate, thereby avoiding long-term overload and causing damage to the steering mechanism.

[0021] In a specific embodiment of the above-mentioned floor scrubber, the position detection mechanism includes at least one position sensor, and the position sensor is arranged on the steering mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not used to limit the scope of protection of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios. For example, although the position sensor in the specification is described in combination with an infrared distance sensor, the present application can obviously use other position sensors, such as optical distance sensors, ultrasonic distance sensors, or micro switches, etc.

[0030] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "set", "connection", etc. 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 the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. It should be understood that the orientation or positional relationship indicated by the terms "rear" and "upper" is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model 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 utility model. In addition, "multiple" in this application means at least two.

[0031] like Figure 1-5 As shown, in order to solve the problem that the steering drive of the existing floor scrubber cannot be powered off in time after the steering is completed, which easily causes the steering drive to be overloaded and damaged, the utility model provides a floor scrubber, including a cleaning body, a steering mechanism, a position detection mechanism and a handheld part. The steering mechanism is connected to the cleaning body, and the steering mechanism is configured to drive the cleaning body to turn; a position detection mechanism is provided on one of the steering mechanism and the cleaning body, and a position identification part is provided on the other, and the position detection mechanism is configured to send a signal outward when the cleaning body rotates to the position detection mechanism corresponding to the position identification part. The handheld part is rotatably connected to the cleaning body.

[0032] In this way, the steering mechanism can drive the cleaning body to turn, and the position detection mechanism and the position identification part can send out a signal when they correspond, so that the steering mechanism can stop driving or reverse driving after the cleaning body turns to the set position, avoiding the failure to cut off the power to the steering mechanism in time after the turning is completed, causing overload damage to the steering mechanism. For example, when the cleaning body needs to turn, the steering mechanism controls the cleaning body to turn relative to the handheld part, and the position detection mechanism can detect the steering angle of the cleaning body relative to the handheld part. When the preset angle is reached, the steering mechanism can be controlled to close, so that the cleaning body can be at this angle for a long time, avoiding overload damage to the steering mechanism.

[0033] In a preferred embodiment, the floor scrubber includes a cleaning body, a cleaning upper shell 3, a support assembly 6, a steering mechanism, a position detection mechanism and a control unit. The cleaning body includes a cleaning base 2 and a cleaning upper shell 3, and the steering mechanism includes a driving mechanism, a driven mechanism and a connecting part 4.

[0034] 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 used for the operator to hold. The steering trigger assembly is arranged near the operator's handheld position, and 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. The steering button 11 is provided with a trigger protrusion, and the contact is connected to the control part. In the initial state, there is a gap between the contact and the trigger protrusion. The two steering buttons 11 correspond to different directions of the washing machine, and it is convenient to control the operation by using the steering button 11. There is a gap between the contact and the trigger protrusion. When the steering button 11 is pressed, the contact and the trigger protrusion will not contact immediately to avoid misoperation. For example, when the left steering button 11 (based on the user's position) is pressed, after the steering button 11 is pressed for a stroke, the trigger protrusion on the left side contacts the corresponding 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.

[0035] 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 specific scenarios. For example, the steering trigger assembly includes a steering slider, a handheld portion 1 is provided with a chute, a steering slider is slidably connected to the chute, and a trigger protrusion is provided on the steering slider. The steering slider can move in the steering chute, and when the steering slider is located at the first end of the chute, the trigger protrusion contacts the corresponding contact, and the control unit receives a signal to control the drive mechanism to rotate, thereby realizing 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 in the middle position of 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 specific scenarios. For example, without using a trigger protrusion, the steering button 11 contacts the contact to realize the control of the reversal. Or a micro switch is used, and the micro switch is connected to the control unit, and when the steering button 11 is pressed, the micro switch at the corresponding position is triggered.

[0036] See attached Figure 2 A placement recess for placing the cleaning component is provided 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 component includes two roller brushes 5 for cleaning the floor, and the roller brushes 5 are placed in the placement recess.

[0037] See attached 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 a position detection mechanism is formed on the cleaning upper shell 3. Of course, the provision of the cleaning upper shell 3 is not necessary, and those skilled in the art can choose whether to provide the cleaning upper shell 3 and the specific structure of the cleaning upper shell 3 based on the specific application scenario, and of course, the cleaning upper shell 3 may not be provided. 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 roller brush 5 are prior art and will not be repeated here.

[0038] See attached Figure 2-3 The support assembly 6 includes two semi-circular support rings 61, each support ring 61 extends a support leg 62 downward, 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 connected to form a circular cavity, and the connecting part 4 passes through the circular cavity. An auxiliary rotating part is arranged between the connecting part 4 and the circular cavity. The auxiliary rotating part is preferably a ball bearing 43. The inner side of the ball bearing 43 is connected to the connecting part 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 part 4 and the support ring 61.

[0039] Of course, the specific structural shape of the support assembly 6 is not unique, and those skilled in the art can adjust it based on specific scenarios. For example, a circular support ring 61 is used. For another example, the support assembly 6 is integrally formed with the cleaning base 2. Of course, the support assembly 6 may not be provided, so that the connecting portion 4 is directly connected to the cleaning upper shell 3. The provision of the auxiliary rotating part is not necessary, and those skilled in the art can choose whether to provide the auxiliary rotating part and the specific structure of the auxiliary rotating part based on the specific application scenario. The auxiliary rotating part can be a shaft sleeve, and of course the auxiliary rotating part may not be provided.

[0040] See attached Figure 3 and 4 The driving mechanism is a driving motor 7, and the driven mechanism is a gear set, which 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 ring gear 8 in the gear set. The driving motor 7 is connected to the cleaning base 2 through a driving connection seat 71, and the driven ring gear 8 in the gear set is integrally formed with the connecting part 4. After the driving motor 7 is started, the driving wheel 72 is driven to rotate and drive the connecting part 4 to rotate, so that the floor scrubber can be turned.

[0041] Of course, the specific setting mode of the driving mechanism and the driven mechanism is not static. Without departing from the principle of the present application, those skilled in the art can adjust it so that the present application is applicable to more specific application scenarios. For example, the positions of the driving motor 7 and the gear set can also be swapped, or adjusted to other positions, such as setting the driving motor 7 on the support assembly 6 through the driving connection seat 71. For another example, the gear set is a spur gear set. For another example, the number of gears in the gear set can be single or multiple, and the transmission is realized by the meshing of multiple gears. For another example, a roller is connected to the driving end of the driving motor 7, and the driven mechanism is a rubber with large friction force. The rubber is connected to the connecting part 4, and the roller is pressed against the rubber to realize that the driving motor 7 drives the connecting part 4 to rotate. For another example, the driving motor 7 is arranged vertically, and a gear is arranged on the driving end of the driving motor 7, and a tooth groove is arranged on the outer side of the lower end of the connecting part 4, and the gear and the tooth groove are meshed. For another example, the driving motor 7 is arranged vertically, and a sprocket is arranged on the driving end of the driving motor 7, and a sprocket is also arranged on the outer side of the lower end of the connecting part 4, and the two sprockets are connected by chain transmission. For another example, the driving motor 7 is vertically arranged, a pulley is arranged on the driving end of the driving motor 7, a pulley is also arranged on the outer side of the lower end of the connecting part 4, and the two pulleys are connected by belt transmission.

[0042] See attached Figure 1-4The 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 hand-held part 1.

[0043] 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.

[0044] See attached Figure 4 and 5 The position detection mechanism includes a position sensor 9 and a protrusion structure 63. The position sensor 9 is installed in the cavity of the cleaning upper shell 3. The position sensor 9 can send a signal to the control unit. Three protrusion structures 63 are arranged on the outside of the second sleeve 42. The three protrusion structures 63 are arranged at intervals along the circumferential direction of the connecting part 4. The protrusion structure 63 located in the middle is arranged to be opposite to the position sensor 9 when the cleaning base 2 is in the return position. The protrusion structures 63 on both sides are arranged at 180 degrees. The protrusion structures 63 on both sides are arranged to be opposite to the position sensor 9 when the cleaning base 2 is in the forward rotation limit position and the reverse rotation limit position.

[0045] In this way, three protrusion structures 63 and one position sensor 9 are used, so that the position sensor 9 can send signals when the cleaning base 2 is at the return position, the forward rotation limit position, and the reverse rotation limit position. For example, when the cleaning base 2 is at the forward rotation limit position, the position sensor 9 detects the protrusion structure 63 and sends a signal, so that the drive motor 7 stops driving the cleaning base 2 to rotate, thereby avoiding long-term overload and causing damage to the drive motor 7.

[0046] Preferably, the position sensor 9 is an infrared distance sensor, and the raised structure 63 is formed by extending the second sleeve 42 outward. When the raised structure 63 is located at the detection end of the infrared distance sensor, the distance detected by the infrared distance sensor becomes shorter, then it is determined that the cleaning base 2 has reached the steering limit position or the return position.

[0047] It should be noted that the setting mode of the position detection mechanism is not fixed, and those skilled in the art can select the specific structure of the position detection mechanism based on the specific application scenario. For example, the position sensor 9 can also be an optical distance sensor, an ultrasonic distance sensor or a micro switch, wherein the principle of the optical distance sensor and the ultrasonic distance sensor is similar to that of the infrared distance sensor, and this application will not repeat them. The micro switch is a switch that uses a very small force. It is a switch in which an external mechanical force acts on the action reed through a transmission element to quickly connect or disconnect the fixed contact and the moving contact at its end. The micro switch can be triggered by using a raised structure 63. For another example, the position sensor 9 and the raised structure 63 can interchange the connection positions. For another example, the raised structures 63 on both sides can be at any angle of 100 degrees, 120 degrees, 160 degrees, 162 degrees, etc.; at the same time, the raised structure 63 in the middle can be opposite to the position sensor 9 when the cleaning base 2 is in a non-returning position. For another example, the number of raised structures 63 can be 1, 2, 3, 4, 5 or 6, etc. For another example, the protruding structure 63 may not be provided, and a recessed structure may be provided on the connecting portion 4. The position sensor 9 is an infrared distance sensor and faces the connecting portion 4. When the infrared distance sensor faces the recessed structure, the distance detected by the infrared distance sensor becomes longer, and it is determined that the cleaning base 2 has reached the turning limit position or the return position.

[0048] It should be further explained that the position detection mechanism may also include three position sensors 9 and a protruding structure 63. The three position sensors 9 are arranged at intervals along the circumferential direction of the connecting portion 4, wherein the position sensor 9 located in the middle is arranged to be opposite to the protruding structure 63 when the cleaning base 2 is in the return position, and the position sensors 9 located on both sides are arranged to be opposite to the protruding structure 63 when the cleaning base 2 is in the forward rotation limit position and the reverse rotation limit position. In this way, different position sensors 9 correspond to different steering positions of the cleaning base 2, so that the steering direction of the cleaning base 2 can be accurately determined by the position sensor 9. Specifically, when the position sensor 9 at the forward rotation limit position is opposite to the protruding structure 63, the position sensor 9 at the corresponding position is triggered, thereby determining that the cleaning base 2 is in the forward rotation limit position.

[0049] The control unit is mounted on the cleaning base 2, and is used to receive signals and control the actions of related components. For example, when the control unit receives a signal from the position sensor 9, the control unit controls the drive motor 7 to stop rotating. The specific selection of the control unit is prior art and will not be repeated here.

[0050] Please refer to the attached Figure 1-5 , a brief introduction is given to the steering process of the floor scrubber of the present application.

[0051] Taking turning left as an example, when the user of the floor scrubber needs the floor scrubber to turn left, he presses the steering button 11 on the left side of the hand-held part 1, and the signal is transmitted to the control part. The control part controls the drive motor 7 to rotate, and the drive motor 7 drives the first sleeve 41 to rotate relative to the cleaning base 2. When the hand-held part 1 does not move, the moving direction of the cleaning base 2 changes, thereby realizing the steering of the cleaning base 2.

[0052] After the cleaning base 2 turns, if the user releases the turn button 11, the drive motor 7 no longer drives the first sleeve 41 to rotate relative to the cleaning base 2. If the user does not release the turn button 11, the convex structure 63 at the left turn limit position is detected by the position sensor 9, and the position sensor 9 sends a signal, which is transmitted to the control unit, and the control unit controls the drive motor 7 to stop rotating. This allows the cleaning base 2 to be at this angle for a long time, avoiding overload and damage to the drive motor 7.

[0053] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0054] 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 easy for those skilled in the art to understand 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.
