Description

Technical Field

[0001] The present invention relates to the field of floor washing machines, and specifically provides a steering trigger mechanism and a floor washing machine. Background Art

[0002] A floor washing machine is a cleaning machine suitable for cleaning hard floors while sucking up sewage and taking the sewage away from the site. The floor washing machine mainly relies on a rotary brush to clean the particulate matter on the ground and suck the particulate matter dissolved in water into the sewage tank. The greater the friction between the rotary brush and the ground, the better the cleaning effect. Of course, on the basis of pursuing the cleaning effect, there are the following pain points in use: when the user holds the floor washing machine to turn, move forward or backward, there is a sense of strain, and it is more inconvenient to use.

[0003] In order to solve the problem of strenuous use, currently, a forward and backward assistance scheme is adopted in common floor washing machines, but there is still a problem of strenuous effort when the floor washing machine turns.

[0004] Correspondingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems and solve the problem of strenuous effort when the existing floor washing machine turns.

[0006] The present invention provides a steering trigger mechanism, including a support part, a handheld part and a trigger assembly;

[0007] A rotation hole is provided on the support part, one end of the handheld part is rotatably arranged in the rotation hole, a limiting groove is provided on one of the outer side of the handheld part and the inner side of the rotation hole, and a limiting block is provided on the other, and the limiting block is arranged to be able to move between the two side walls of the limiting groove;

[0008] The trigger assembly is connected to one of the limiting block and the limiting groove, and the trigger assembly is arranged to be triggered when the limiting block moves and abuts against one of the side walls of the limiting groove.

[0009] In the case of adopting the above technical solution, relative rotation can occur between the handheld part and the support part, the limiting block moves in the limiting groove as the handheld part rotates, and the trigger assembly will be triggered when the limiting block abuts against the side wall of the limiting groove. The trigger assembly can send out a signal outward to make the floor washing machine turn, solving the problem of strenuous effort when the existing floor washing machine turns.

[0010] In a specific embodiment of the above steering trigger mechanism, the limiting groove is provided on the inner side of the rotation hole, and the limiting block is provided on the outer side of the handheld part.

[0011] In the specific implementation of the above-mentioned steering trigger mechanism, the trigger component is a microswitch or a contact switch, and the microswitch or the contact switch is connected to the side wall of the limit groove; or

[0012] The limit block is a conductive metal block, and the trigger component includes a metal sheet, and the metal sheet is arranged on the side wall of the limit groove.

[0013] In the case of adopting the above technical solution, the microswitch or the contact switch is connected to the side wall of the limit groove. When the limit block abuts against the side wall of the limit groove, the microswitch or the contact switch will be triggered, thereby sending a steering signal. When the limit block is a conductive metal block and the trigger component includes a metal sheet, when the limit block abuts against the side wall of the limit groove, the limit block is conducted with the metal sheet, thereby sending a steering signal.

[0014] In the specific implementation of the above-mentioned steering trigger mechanism, it further includes a return component, and the return component is arranged between the support part and the handheld part. The return component is configured to store potential energy when the limit block moves and abuts against one of the side walls of the limit groove, and this potential energy can drive the handheld part to rotate back.

[0015] In the case of adopting the above technical solution, after the handheld part and the support part rotate relative to each other, the return component can drive the handheld part to rotate back, which is convenient for rotating the handheld part next time.

[0016] In the specific implementation of the above-mentioned steering trigger mechanism, a return hole is arranged at one end of the handheld part located in the rotation hole, and the return component is arranged in the return hole.

[0017] In the specific implementation of the above-mentioned steering trigger mechanism, the return component includes a baffle, an elastic member and a rotating member. The baffle is connected to the return hole, the rotating member is connected to the support part and is rotatably inserted into the return hole, and the elastic member is arranged between the baffle and the rotating member.

[0018] In the case of adopting the above technical solution, when the rotating member rotates, the elastic member stores elastic potential energy, so that the rotating member can return to the position before rotation, thereby enabling the handheld part to return to the correct position.

[0019] In the specific implementation of the above-mentioned steering trigger mechanism, the rotating member is a rotating cylinder, and a notch for the baffle to rotate is formed on the rotating cylinder, and the baffle passes through the notch.

[0020] In the case of adopting the above technical solution, when the handheld part rotates relative to the support part, the notch enables the baffle to have sufficient movement space, avoiding hindering the rotation of the baffle.

[0021] In the specific implementation manner of the above-mentioned steering trigger mechanism, a pressing block is arranged inside the rotating cylinder, the elastic member includes a spring, one end of the spring abuts against the baffle, and the other end of the spring abuts against the pressing block.

[0022] In the case of adopting the above technical solution, when the handheld part rotates relative to the support part, the distance between the pressing block and the baffle changes, so that the elastic potential energy of the spring changes. The elastic potential energy can make the distance between the pressing block and the baffle return to the initial distance, so that the handheld part can return to the upright position.

[0023] In the specific implementation manner of the above-mentioned steering trigger mechanism, an arc-shaped hole is formed in one end of the handheld part, and an insertion rib is arranged on the support part. The insertion rib is inserted into the arc-shaped hole, and the insertion rib can reciprocate in the arc-shaped hole.

[0024] In the case of adopting the above technical solution, the insertion rib can reciprocate in the arc-shaped hole, which is convenient for the relative rotation between the handheld part and the support part.

[0025] The present invention also provides a floor washer, which includes a cleaning base, a steering assembly and the above-mentioned steering trigger mechanism; the lower side of the support part is connected to the steering assembly, the steering assembly is connected to the cleaning base, and the steering assembly is configured to receive the steering signal sent by the trigger assembly and drive the cleaning base to turn.

[0026] In the case of adopting the above technical solution, relative rotation can occur between the handheld part and the support part. The limiting block moves in the limiting groove as the handheld part rotates. When the limiting block abuts against the side wall of the limiting groove, the trigger assembly will be triggered. The trigger assembly can send out signals outward and drive the floor washer to turn through the steering assembly, solving the problem that the existing floor washer is laborious to turn.

Detailed implementation manners

[0039] The following describes the preferred implementation manners of the present application 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 inserted bars in the specification are described in combination with six, obviously, the present application can adopt other numbers of inserted bars, such as one, two, or three, etc.

[0040] It should be noted that in the description of this application, unless otherwise clearly specified and defined, terms such as "set" and "connected" should be understood in a broad sense. For example, "connected" 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", "outer", "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 to the present invention. In addition, "a plurality of" in this application means at least two.

[0041] The preferred embodiments of the present invention will be described below with reference to the drawings, in which: Figure 1 is a schematic diagram of the overall structure of the floor washer; Figure 2 is a schematic diagram of the structure on the lower side of the handheld part in the steering trigger mechanism; Figure 3 is a schematic diagram of the structure on the upper side of the support part in the steering trigger mechanism; Figure 4 is a cross-sectional view of the steering trigger mechanism; Figure 5 is an enlarged cross-sectional view of the connection part between the handheld part and the support part in the steering trigger mechanism; Figure 6 is a cross-sectional view of the support part in the steering trigger mechanism; Figure 7 The structure diagram of the return component in the steering trigger mechanism; Figure 8 is a structure diagram of the cleaning base in the floor washer; Figure 9 is a structure diagram of the steering component in the floor washer; Figure 10 is a cross-sectional view of the support component and related connection structures in the floor washer.

[0042] The steering trigger mechanism of this application will be introduced below in combination with the floor washer. As Figures 1 - 7 shown, to solve the problem that the existing floor washer is laborious to turn, the present invention provides a steering trigger mechanism, which includes a support part 2, a handheld part 1 and a trigger component; a rotation hole 21 is provided on the support part 2, and one end of the handheld part 1 is rotatably arranged in the rotation hole 21. A limiting groove 23 is provided on one of the outer side of the handheld part 1 and the inner side of the rotation hole 21, and a limiting block 11 is provided on the other. The limiting block 11 is arranged to be able to move between the two side walls of the limiting groove 23; the trigger component is connected to one of the limiting block 11 and the limiting groove 23, and the trigger component is arranged to be triggered when the limiting block 11 moves and abuts against one of the side walls of the limiting groove 23.

[0043] In this way, relative rotation can occur between the handheld part 1 and the support part 2. The limit block 11 moves in the limit groove 23 as the handheld part 1 rotates, and the trigger assembly is triggered when the limit block 11 abuts against the side wall of the limit groove 23. The trigger assembly can emit a signal outward to make the floor washer turn, solving the problem that the existing floor washer is laborious to turn.

[0044] See the appendix Figures 1 - 7 , in a preferred embodiment, the steering trigger mechanism includes a support part 2, a handheld part 1, a trigger assembly, and a return-to-center assembly 3. Among them, the trigger assembly is a micro switch, and the return-to-center assembly 3 includes a baffle 31, an elastic member, and a rotating member.

[0045] See the appendix Figure 3 and 5 , a rotating hole 21 is provided on the upper side of the support part 2, and six inserting ribs 22 parallel to the length direction of the rotating hole 21 are provided at the bottom of the rotating hole 21. A limit groove 23 is provided on the inner side wall of the rotating hole 21.

[0046] See the appendix Figure 2 , the handheld part 1 and the support part 2 are concentrically arranged. One end of the handheld part 1 is rotatably arranged in the rotating hole 21. A limit block 11 is provided on the outside of the handheld part 1, and the limit block 11 is arranged to be able to move between the two side walls of the limit groove 23 (that is, the limit block 11 rotates around the axis of the handheld part 1). A return-to-center hole 12 is provided at the central position of one end of the handheld part 1 located in the rotating hole 21. The return-to-center assembly 3 is arranged in the return-to-center hole 12. Six arc-shaped holes 13 are provided outside the return-to-center hole 12. The arc-shaped holes 13 and the inserting ribs 22 are arranged corresponding to each other. The inserting ribs 22 are inserted into the arc-shaped holes 13, and the inserting ribs 22 can reciprocally move around the arc center of the arc-shaped holes 13 in the arc-shaped holes 13. In this way, the inserting ribs 22 can reciprocally move in the arc-shaped holes 13, facilitating the relative rotation between the handheld part 1 and the support part 2.

[0047] It should be noted that the above setting method is not the only one, and those skilled in the art can select specific setting methods according to specific application scenarios. For example, the positions of the limit groove 23 and the limit block 11 can be interchanged, the limit groove 23 is provided on the outside of the handheld part 1, and the limit block 11 is provided on the inner side wall of the rotating hole 21. For another example, the positions of the inserting ribs 22 and the arc-shaped holes 13 are interchanged. For another example, the return-to-center hole 12 is not provided on the handheld part 1, but is provided on the lower side of the rotating hole 21. For another example, the number of the inserting ribs 22 and the arc-shaped holes 13 can be 1, 2, 3, 4, 5 or more. For another example, the number of the inserting ribs 22 and the arc-shaped holes 13 can be different, and the number of the arc-shaped holes 13 can be greater than the number of the inserting ribs 22.

[0048] The triggering component is a microswitch, and the microswitch is connected to the side wall of the limit slot 23. In this way, the microswitch is connected to the side wall of the limit slot 23. When the limit block 11 abuts against the side wall of the limit slot 23, the microswitch will be triggered, thereby sending a steering signal.

[0049] It should be noted that the setting method of the triggering component is not unique, and those skilled in the art can select the specific structure of the triggering component according to the specific application scenario. For example, the triggering component can also be a contact switch, and the triggering principle of the contact switch is the same as that of the microswitch, which will not be elaborated here. Another example is that the triggering component can also be a metal sheet, the limit block 11 is a conductive metal block, the metal sheet is arranged on the side wall of the limit slot 23. When the limit block 11 abuts against the side wall of the limit slot 23, the limit block 11 is conducted with the metal sheet, thereby sending a steering signal.

[0050] See attached Figure 3 and 5 Figure 7, the return component 3 includes a baffle 31, a rotating cylinder 32 and a spring 33. One end of the rotating cylinder 32 ( Figure 7 the end close to the paper surface in the figure) is connected to the bottom surface of the rotating hole 21 ( Figure 3 the surface shown in the figure), and is rotatably inserted into the return hole 12. Two clamping grooves 121 are arranged on the return hole 12, and both ends of the baffle 31 are respectively inserted into the clamping grooves 121. A notch 322 for the baffle 31 to rotate is arranged on the rotating cylinder 32. The baffle 31 passes through the notch 322. Two pressing blocks 321 are arranged in the rotating cylinder 32. The two pressing blocks 321 are arranged oppositely, and the pressing blocks 321 and the notch 322 are arranged at a 90-degree angle. The number of the springs 33 is four. One end of each of the four springs 33 abuts against the baffle 31, and the other end abuts against the pressing block 321. And in the case of no external force participation, the lengths of the four springs 33 are the same, and the baffle 31 is located at the middle position of the notch 322. In this way, when the rotating cylinder 32 rotates, the spring 33 stores elastic potential energy, so that the rotating cylinder 32 can return to the position before rotation, thereby enabling the holding part 1 to return to the correct position.

[0051] Wherein, a plugging groove for connecting the rotating cylinder 32 is arranged on the bottom surface of the rotating hole 21. One end of the rotating cylinder 32 is inserted into the plugging groove and bonded, so as to realize the connection between one end of the rotating cylinder 32 and the bottom surface of the rotating hole 21. Of course, other connection methods can also be selected as long as the fixed connection between the rotating cylinder 32 and the rotating hole 21 can be realized. For example, a connecting ear is arranged on the bottom surface of the rotating hole 21, a connecting hole is arranged on the connecting ear, and a connecting block is arranged on the outer side wall of the rotating cylinder 32, and the connecting block is arranged in the connecting hole.

[0052] It should be noted that the provision of the return assembly 3 is not mandatory, and those skilled in the art can choose whether to provide the return assembly 3 and the specific structure of the return assembly 3 based on the specific application scenario. For example, the return hole 12 may not be provided with the engaging groove 121, and the baffle 31 can be directly fixed to the return hole 12 using glue.

[0053] For another example, instead of the rotating cylinder 32, a rotating frame can be used. The rotating frame includes two pressing blocks 321 connected to the bottom surface of the rotating hole 21. One end of the spring 33 tightens the pressing blocks 321, while the other end tightens one end of the baffle 31. In this way, when the handheld portion 1 rotates relative to the support portion 2, the distance between the pressing blocks 321 and the baffle 31 changes, thereby causing the elastic potential energy of the spring 33 to change. The elastic potential energy can restore the distance between the pressing blocks 321 and the baffle 31 to the initial state, thereby allowing the handheld portion 1 to return to its original position.

[0054] For another example, the return assembly 3 can be a torsion spring, which is mounted on the handle 1, with one end of the torsion spring connected to the handle 1 and the other end of the torsion spring connected to the support 2. When the handle 1 rotates relative to the support 2, the torsion spring stores elastic potential energy, and the stored elastic potential energy can return the handle 1 to its original position. For another example, the return assembly 3 can be omitted. For another example, the number of springs 33 can be one spring 33 of a fixed length, or two or three. For another example, the number of clamping blocks 321 can be one, with only two springs 33 used to press against both sides of the clamping block 321.

[0055] See attached Figure 1 and 8 -10. The present invention also provides a floor scrubber comprising a cleaning base 5, a steering assembly, and the aforementioned steering trigger mechanism. The underside of the support portion 2 is connected to the steering assembly, which is in turn connected to the cleaning base 5. The steering assembly is configured to receive a steering signal from the trigger assembly and drive the cleaning base 5 to steer. This allows relative rotation between the handle 1 and the support portion 2. The limit block 11 moves within the limit slot 23 as the handle 1 rotates. The trigger assembly is triggered when the limit block 11 abuts the sidewall of the limit slot 23. The trigger assembly can send a signal outward, causing the floor scrubber to turn, thus resolving the difficulty experienced by existing floor scrubbers in steering.

[0056] See attached Figures 8 - 10 In a preferred embodiment, the steering assembly includes a connecting portion 4, a driving motor 7, and a gear set. A supporting assembly 6 is provided on the cleaning base 5.

[0057] The supporting assembly 6 includes two semi-circular supporting rings 61. Each supporting ring 61 extends downward to form supporting legs 62. The upper ends of the supporting legs 62 are connected to the supporting rings 61, and the lower ends of the supporting legs 62 are connected to the cleaning base 5. The two supporting rings 61 are butted and enclosed 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 supporting ring 61. The ball bearing 43 enables relative rotation between the connecting portion 4 and the supporting ring 61.

[0058] Of course, the specific structural shape of the supporting assembly 6 is not unique, and those skilled in the art can adjust it based on the specific scenario. For example, a circular supporting ring 61 is adopted. Another example is that the supporting assembly 6 and the cleaning base 5 are integrally formed. Of course, the supporting assembly 6 can also be not provided, and the connecting portion 4 is directly connected to the cleaning upper shell. The setting of the auxiliary rotating member is not necessary, and those skilled in the art can choose whether to set the auxiliary rotating member and the specific structure of the auxiliary rotating member 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 provided.

[0059] 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 gear 72 of the gear set is provided on the driving end of the driving motor 7, and the driving gear 72 meshes with a driven gear ring 8 of the gear set. The driving motor 7 is connected to the cleaning base 5 through a driving connection seat 71. The driven gear ring 8 of the gear set is integrally formed with the connecting portion 4. After the driving motor 7 is started, it drives the driving gear 72 to rotate and drives the connecting portion 4 to rotate, that is, the floor washer can be steered.

[0060] Of course, the specific setting methods of the driving mechanism and the driven mechanism are not fixed. Without departing from the principle of this application, those skilled in the art can adjust them so that this 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 base 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 achieved through the meshing of multiple gears. For another example, a roller is connected to the driving end of the driving motor 7, the driven mechanism is rubber with a large frictional force, the rubber is connected to the connecting portion 4, and the roller is pressed against the rubber to drive the connecting portion 4 to rotate by the driving motor 7. For another example, the driving motor 7 is vertically arranged, 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 portion 4, and the gear and the tooth groove are meshed. For another example, the driving motor 7 is vertically arranged, 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 portion 4, and the two sprockets are connected by a chain drive. For another example, the driving motor 7 is vertically arranged, a pulley is arranged on the driving end of the driving motor 7, and a pulley is also arranged on the outer side of the lower end of the connecting portion 4, and the two pulleys are connected by a belt drive.

[0061] See the appendix Figures 9 - 10 , the connecting portion 4 includes a first sleeve 41 and a second sleeve 42. A driven gear ring 8 is integrally arranged at the lower end of the first sleeve 41, and the first sleeve 41 passes through the circular cavity; the upper end of the second sleeve 42 is connected to the lower side of the support portion 2, a thread is arranged on the inner side of the lower end of the second sleeve 42, and it is threadedly connected to the upper end of the first sleeve 41, and the upper end of the second sleeve 42 is connected to the lower end of the support portion 2.

[0062] Of course, the setting of the connecting portion 4 is not necessary. Those skilled in the art can select the specific structure of the connecting portion 4 based on the specific application scenario. For example, the first sleeve 41 and the driven gear ring 8 are separately arranged and connected by threads; for another example, the second sleeve 42 passes through the circular cavity, a thread is arranged on the outer side of the lower end of the second sleeve 42, and it is threadedly connected to the first sleeve 41, etc.

[0063] The following introduces the possible usage methods in combination with the preferred implementation manners.

[0064] Taking a left turn as an example for illustration, when the floor washer user needs the floor washer to turn left, turn the hand-held part 1 to the left, the left side of the limit block 11 contacts the left inner wall of the limit groove 23, the micro switch located on the left side of the limit groove 23 is triggered, and a signal for controlling the cleaning base 5 to turn left is sent, controlling the driving motor 7 to rotate. The driving motor 7 drives the first sleeve 41 to rotate relative to the cleaning base 5, thereby realizing the turning of the cleaning base 5.

[0065] When the handheld part 1 is rotated leftward, the baffle 31 rotates with the handheld part 1. The side surface of the baffle 31 contacts the side surface of a notch 322, and two springs 33 are compressed and store elastic potential energy. After the rotation of the handheld part 1 stops, the elastic potential energy is released, the baffle 31 returns to the middle position of the notch 322, and the handheld part 1 returns to the upright position.

[0066] Those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that they are within the scope of this application and form different embodiments. For example, in the claims of this application, any one of the claimed embodiments can be used in any combination.

[0067] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the 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.
