Description

Technical Field

[0001] The present invention relates to the field of cleaning tools, and in particular, to a floor cleaning device. Background Art

[0002] With the continuous development of automated production and productivity, there have been great improvements in household appliances and tools. There are various automated tools and supplies in all fields of people's lives. When supplies or tools have automated components, which can save labor costs and time, it achieves the purpose of fully optimizing people's lives and production.

[0003] Currently, in the use of mops in household cleaning supplies, users usually actively absorb water with the mop and wipe the ground with the water-absorbed mop to achieve the cleaning effect. However, this method is too laborious. Each time, the user needs to take the mop to a place with water to re-absorb water and wet the mop assembly, which is very inconvenient. At the same time, when cleaning the mop, it is often necessary to manually disassemble the mop from the mop housing or rack and clean the disassembled mop. This cannot free the user's hands and cannot achieve the technical effect of quickly and conveniently using the cleaning tool for cleaning.

[0004] In addition, when disassembling and installing the floor cleaning device, it is often manually operated to remove the floor cleaning device from the housing. However, such an operation is too laborious. For the user, it is also necessary to bend down or even squat down to operate, which reduces the user experience.

[0005] In addition, when the existing floor cleaning device is mopping the floor, it often requires the user to actively install or remove the water tank. Otherwise, the stored water in the water tank will excessively wet the mop of the floor cleaning device, resulting in a large amount of water overflowing, polluting the floor, and even damaging the wooden floor.

[0006] In view of the above problems, no effective solution has been proposed yet. Summary of the Invention

[0007] An embodiment of the present invention provides a floor cleaning device to at least solve the technical problem that the water in the water tank of the mop module in the prior art cannot be stopped automatically.

[0008] According to one aspect of an embodiment of the present invention, a floor cleaning device is provided, which includes a water tank assembly. The water tank assembly includes a water tank and a mop at the bottom of the water tank. It further includes: a water volume control assembly, which includes a knob and a water control plate; a water passing assembly, which includes a water tank hole, a water outlet hole, and a water passing channel. The water tank hole is communicated with the inside of the water tank, and the water outlet hole is communicated with the outside for supplying water to the mop. The water passing channel connects the water tank hole and the water outlet hole; an air intake assembly, which includes an air intake hole provided at the bottom of the water tank and an air intake pipeline extending from the air intake hole to the upper part of the water tank.

[0009] Further, the knob is connected to the water control plate through a knob rod, and by rotating the knob, the water volume entering the water control holes of the water control plate from the inside of the water tank through the water tank hole can be controlled.

[0010] Further, the water passing channel is a hollow channel provided at the bottom of the water tank. The water passing channel includes a starting part cooperating with the water control plate, a terminal part corresponding to the water outlet hole, and a curved path located between the starting part and the terminal part.

[0011] Further, when the floor cleaning device is hung, the air intake hole is located between the starting part and the terminal part, and the terminal part is higher than the starting part.

[0012] Further, a water tank bottom cover is arranged between the water tank and the mop. The water passing channel is formed on the surface where the water tank bottom cover and the bottom surface of the water tank are combined, and the water outlet hole is provided on the water tank bottom cover.

[0013] Further, the floor cleaning device further includes a pedal linkage assembly for controlling the locking and unlocking of the floor cleaning device and the cleaning equipment.

[0014] Further, the pedal linkage assembly includes: a pedal assembly and a locking assembly; the pedal assembly includes: a pedal, an inner protrusion of the pedal, a rotating shaft, and a rotating reset mechanism; the locking assembly includes: a locking shaft, a linkage part, a locking part, and a locking shaft reset mechanism; the inner protrusion of the pedal interacts with the linkage part to achieve the locking and unlocking of the floor cleaning device and the cleaning equipment.

[0015] Further, a mop cleaning assembly is further included, which is clamped on the water tank. When the mop needs to be cleaned, it can be disengaged from the clamped state to scrape and wash the mop provided at the bottom of the water tank.

[0016] Further, the mop cleaning assembly includes a handle and a scraping blade. The handle is used to operate the mop cleaning assembly so that the scraping blade can scrape and wash the mop along the entire length direction of the water tank.

[0017] Further, the inner diameter of the intake pipeline is greater than or equal to the diameter of the intake hole, and the end of the intake pipeline is substantially abutted against the top of the inner wall of the water tank.

[0018] Further, the end of the intake pipeline is formed into a serrated shape, and the top of the serrated shape is substantially abutted against the top of the inner wall of the water tank.

[0019] Further, the intake pipeline and the water passing channel are separated by water in the water tank, and the mop absorbs water and expands to block the intake pipeline.

[0020] In the present invention, by means of the key spring, when the flange hole is not communicated with any water tank hole, water will not leak out from the water tank hole, maintaining good sealing. At the same time, the rebounding force generated will provide a feedback force for the operator, enabling the user to feel the tactile change of the rotation gear and bringing better comfort in the rotation operation; through the setting of the knob steel ball, when it moves to the concave part on the side wall of the rotary accommodating groove, the gear of the knob upper cover is automatically locked again, and the water adjustment process is accurate and controllable.

[0021] The mop cleaning assembly is held by hand for cleaning. By reciprocally squeezing the mop body in the water tank assembly, the mop can be fully cleaned. At the same time, the distance between the side surface of the second plate in contact with the lower surface of the water tank mop and the water tank mop can be dynamically adjusted, and the dehydration is sufficient and simple, achieving the technical effect of liberating both hands for cleaning.

[0022] By setting the pedal shaft and the locking shaft, stepping on the pedal of the floor cleaning device with the toes can achieve the fixed connection and release of the floor cleaning device and the connecting rod, solving the technical problem of manual disassembly and installation of the floor cleaning device.

[0023] By setting the air pressure sealing effect between the water tank intake hole and the mop of the floor cleaning device, when the above-mentioned floor cleaning device is placed flat, the water in the water tank body will not overflow and cause pollution; when the floor cleaning device is in a suspended state, since the position of the water tank hole is lower than the positions of the water outlet hole and the intake hole, hanging water stop can be achieved, and the water in the water tank body will not overflow and cause pollution.

The knob rod 23 is outer-circuited with a button spring 27. The button spring 27 can be installed by welding or fitting. The upper and lower ends of the button spring 27 respectively abut against the knob cover 21 and the lower bracket 14 of the water tank.

[0071] After the knob is rotated, under the action of the restoring force of the button spring 27, the upper surface of the annular water control disk at the lower end of the knob rod 23 quickly clings to the lower surface of the bottom shell of the water tank lower shell 12, thereby preventing water from leaking out of the water tank hole 15 when the water control hole 24 is not connected to any water tank hole 15, thereby maintaining a better seal.

[0072] At the same time, when the user implements the embodiment of the present invention, after the knob is pressed down, the knob steel ball 25 will fall out of the recessed portion of the side wall of the rotary accommodating groove, and the knob upper cover 21 will be unlocked. At this time, the knob upper cover 21 can be rotated to the corresponding gear at will, and then the knob is released. The knob upper cover 21 moves upward under the action of the restoring force of the button spring 27, and when it moves to the recessed portion of the side wall of the rotary accommodating groove, the knob steel ball 25 on the side of the knob upper cover 21 abuts against the recessed portion of the side wall of the rotary accommodating groove again under the action of the knob steel ball spring 26, thereby realizing the automatic locking of the knob upper cover 21 gear again, ensuring that the gear returns to the correct position when it is turned.

[0073] In addition, the rebound force generated by the knob after rotation will provide feedback force to the operator, allowing the user to feel the tactile changes in the rotation gear, bringing better comfort in the rotation operation, increasing the user's experience when using the knob to adjust the water volume, and at the same time making the process of adjusting the water volume more precise and controllable.

[0074] It should be noted that the water tank mop 18 is connected to the bottom of the water tank lower shell 12. The water tank mop 18 is used to clean the floor and is the main body that acts when water is released. It can be made of textile fabric and releases water through a control device to soak the mop assembly, thereby achieving the technical purpose of soaking the mop assembly for cleaning at any time.

[0075] Specifically, the upper knob cover 21 is a rotary body. A circular groove is provided below the upper knob cover 21, and the knob screw 22 is rigidly embedded in the circular groove. A knob decorative piece 28 is installed on the upper side of the upper knob cover 21 for indicating gear identification positioning when the user rotates. The above-mentioned knob decorative piece 28 is made of anti-corrosive hard plastic and is rigidly connected to the upper knob cover 21. The upper knob cover 21 is a regular circular device, and a protrusion is provided along the vertical radius at the center of the knob device. The knob decorative piece 28 is arranged on the upper surface of the protrusion. The knob steel balls 25 and the knob steel ball springs 26 are installed on both sides of the upper knob cover 21 by means of abutting and linkage with the upper shell 11 of the water tank.

[0076] Specifically, steel ball holes are symmetrically provided on the side of the upper knob cover 21. The knob steel ball springs 26 and the knob steel balls 25 are installed in the steel ball holes in sequence from the inside to the outside. The knob steel ball springs 26 provide a thrust force towards the outside of the hole for making the knob steel balls 25 abut against the concave part on the side wall of the rotary accommodation groove. The axis of the steel ball hole is perpendicular to the axis of the knob screw 22.

[0077] The knob steel balls 25 are rigid spherical bodies and are in an interference fit state with the concave part on the side wall of the rotary accommodation groove.

[0078] Optionally, a water tank magic tape 17 is installed on the lower side of the water tank bottom cover 13. Among them, the water tank magic tape 17 is connected to the water tank bottom cover 13 by adhesion. The water tank mop 18 is connected to the water tank bottom cover 13 through the water tank magic tape 17. In order to facilitate the user to install the mop device of the mopping module, the water tank magic tape 17 is adhesively bonded to the bottom of the water tank through solid glue, and the mop of the mopping module is pasted or removed through the above-mentioned water tank magic tape 17.

[0079] When the handle 31 is engaged with the outer surface inside the upper shell 11 of the water tank, the plane where the first plate body 33 is located is parallel to the plane where the upper shell 11 of the water tank is located, and the plane where the second plate body 34 is located is parallel to the plane where the upper shell 11 of the water tank is located.

[0080] When the handle 31 slides in contact with the lower surface of the water tank mop 18, the distance between the side surface of the second plate body 34 in contact with the lower surface of the water tank mop 18 and the water tank mop 18 is variable.

[0081] A number of concave and convex stripes are processed on the side surface of the second plate body 34 in contact with the lower surface of the water tank mop 18 for increasing the sliding friction force of the second plate body 34 and improving the effect of mopping and cleaning by scraping the mop.

[0082] The handle 31 can rotate around the sliding feet 35 of the first plate body 33 as the axis. During the rotation operation, the handle 31 disengages from the handle accommodation groove and rotates to the outer surface side of the lower shell 12 of the water tank.

[0083] One end of the sliding foot 35 away from the second plate body 34 is provided with a scraping blade 36. By compressing the scraping blade 36 with the sliding foot 35, the second plate body 34 can be moved towards the water tank mop 18, so that surface contact can be achieved for different types of mops. At the same time, during the dehydration process of the mop, the size of the mop will also shrink. Through the scraping blade 36, the distance between the side surface of the second plate body 34 in contact with the lower surface of the water tank mop 18 and the water tank mop 18 can be dynamically adjusted to achieve repeated dehydration of the mop.

[0084] The sliding foot 35 of the second plate body 34 can slide back and forth along the through direction of the sliding groove 19. To prevent the handle 31 from falling off the water tank body, a stop rubber plug is provided at one end of the sliding groove 19 away from the accommodating groove of the handle 31. The stop rubber plug is in the shape of a cuboid and is fixedly adhered to one side in the sliding groove 19 to prevent the sliding foot 35 of the handle 31 from sliding out of the sliding groove 19.

[0085] The hand - holding groove 32 is provided on one side of the water tank upper shell 11, which is used to make the user grip the mop assembly more firmly. The above - mentioned hand - holding groove 32 can be processed by a downward - concave method or a ring - shaped handle method. The specific processing method is not limited here, that is, it is ensured that the use of the hand - holding groove 32 is to grip more firmly, and it is used to grip the water tank body.

[0086] The hand - holding groove 32 can be a groove - type component made of the same material as the function panel, and is adhesively or snap - connected to the water tank assembly. When the user needs to clean the mop, the user needs to firmly hold the entire floor cleaning device with the hand. At this time, according to the setting of the hand - holding groove 32, the user can hold the groove part with the hand to achieve the technical effect of firmly holding the floor cleaning device.

[0087] Preferably, the hand - holding groove 32 is integrally formed in the middle of the outer surface of the water tank upper shell 11, and the hand - holding groove 32 is an arc - shaped concave part embedded on the function panel on the front of the mop.

[0088] The mop can be an ordinary textile for cleaning the floor, and is fixed in the shell through a fixing device. When the user uses the mop assembly to clean the floor, the mop assembly can clean the dust or garbage on the floor. Among them, the shell can be made of metal or environmentally friendly hard plastic. The above - mentioned mop assembly is fixed in the shell through a fixing device to form an integral mopping device.

[0089] The handle 31 can be a pull - type handle 31 made of environmentally friendly hard plastic. When not in use usually, it is retracted into the water tank assembly. When the user needs to use the handle 31 to clean the mop, the handle 31 needs to be pulled out so that the handle 31 can be operated to achieve the technical effect of cleaning the mop.

[0090] Specifically, in order to clean the mop device of the mopping module through the handle 31, the handle 31 can be designed to be used in a pull-out manner, that is, a pull-out component is arranged on the handle 31 for pulling out the handle 31 from the mop. After the user grabs the handle 31, pulling or pushing forcefully can achieve the operations of pulling out and retracting the handle 31.

[0091] Specifically, after the user pulls and retracts the handle 31 through the embodiment of the present invention, a rotation operation needs to be performed on the handle 31 to make the handle 31 in a working state. The handle 31 cleans the mop in the working state, and the handle 31 is in a state that can be used by the user. In this state, the user only needs to operate the handle 31 according to the following method to achieve the technical purpose of quickly cleaning the mop.

[0092] Specifically, after the user rotates the handle 31, the handle 31 can be slid along the through direction of the chute 19 of the water tank lower shell 12. The user needs to hold the handle of the handle 31 and slide the handle 31 back and forth along the direction of the chute 19, so as to achieve the technical effect of fully cleaning the mop by reciprocally squeezing the mop body in the water tank assembly. Among them, the mop in the mopping module can be made of a textile fabric with a certain toughness.

[0093] Specifically, in order to prevent the user from causing unnecessary over-force damage or sliding out of the chute 19 during the process of sliding the handle 31 along the chute 19, a stop rubber plug is arranged on one side of the chute 19 for soft stopping when the handle 31 is slid to a certain position by the user, so as to inform the user that this position is the limit position and it is not suitable to continue pushing or pulling the handle 31 forcefully.

[0094] During the use of the embodiment of the present invention, one hand takes out the mop cleaning device from the water tank assembly, and the other hand holds the handle groove 32 of the mop cleaning device. The mop is located on the lower side of the water tank lower shell 12. The handle 31 is flipped 180°. The handle 31 moves back and forth along the chute 19 of the water tank assembly. The handle 31 is designed with a scraping blade 36 for keeping surface contact. By compressing the scraping blade 36 through the sliding foot 35, the second plate body 34 can be moved towards the water tank mop 18, so as to dynamically adjust the distance between the side surface of the second plate body 34 in contact with the lower surface of the water tank mop 18 and the water tank mop 18 for different mop types, realizing full dehydration of the mop, thereby achieving the function of cleaning the mop without using both hands.

[0095] In addition, in order to control the handle 31 to move benignly along the track, a stop rubber plug is designed in the chute 19.

[0096] The included angle between the extending direction of the linkage part 44 and the extending direction of the locking part 45 is θ, and 90° ≤ θ < 180°.

[0097] Preferably, the included angle θ between the extending direction of the linkage part 44 and the extending direction of the locking part 45 satisfies 120° < θ < 150°.

[0098] A pedal inner protrusion 46 is integrally extended on the lower surface of the pedal 41. Two limit protrusions are provided on the surface of the linkage part 44 of the locking shaft 43 facing the pedal 41. The pedal inner protrusion 46 cooperates with the two limit protrusions to limit the pressing position and the reset position of the pedal 41.

[0099] A locking protrusion is provided on the surface of the locking part 45 of the locking shaft 43 away from the pedal 41. The connecting rod of the floor cleaning device has a locking groove, and the locking protrusion can be inserted into the locking groove to fix the floor cleaning device to the connecting rod.

[0100] The extending end of the locking part 45 is conical, which is convenient for guiding the locking protrusion of the locking part 45 to be inserted into the locking groove of the connecting rod of the floor cleaning device.

[0101] An upper return spring is sleeved on the hinged part of the rotating shaft 42 and the upper shell 11 of the water tank. The upper return spring provides a restoring force to make the pedal 41 move upward. A lower return spring is sleeved on the hinged part of the locking shaft 43 and the lower shell 12 of the water tank. The lower return spring provides a restoring force to make the linkage part 44 of the locking shaft 43 move upward and the locking part 45 move downward.

[0102] Anti-slip grooves are arranged horizontally on the pedal 41. Specifically, the anti-slip grooves are arranged in an arithmetic progression on the upper surface of the pedal 41.

[0103] Specifically, the pedal 41 of the pedal linkage device according to the embodiment of the present invention is used to provide a foot stepping position for the user. The user can unlock the floor cleaning device by stepping on the pedal 41, which is convenient for the user to remove and install the floor cleaning device. The locking shaft 43 and the rotating shaft 42 can be made of wear-resistant metal materials, and are used to perform displacement processing and locking processing on the pedal 41 when the user uses the pedal 41.

[0104] Depressed positioning grooves are processed on both sides of the rotating shaft 42, and a torsion spring of the rotating shaft 42 is installed on the depressed positioning grooves, which is used for performing a return operation when the rotating shaft 42 rotates.

[0105] Depressed positioning grooves are processed on both sides of the locking shaft 43, and a torsion spring of the locking shaft 43 is installed on the depressed positioning grooves, which is used for performing a return operation when the locking shaft 43 rotates.

[0106] When the user steps on the pedal, the pedal 41 drives the rotating shaft 42 to rotate. Then, in order to return the pedal 41, a torsion spring of the rotating shaft 42 needs to be installed on the rotating shaft 42. Among them, the function of the torsion spring can be to perform automatic return by generating a reverse torque.

[0107] The upper surface of the locking shaft 43 is in contact with the rigid protrusion on the lower surface of the pedal 41 for linkage with the pedal 41. Among them, the protrusion is a triangular protrusion, and its vertex contacts the limit protrusion of the locking shaft 43 as a contact point. The rigid protrusion on the lower surface of the pedal 41 is the inner protrusion 46 of the pedal, which cooperates with the two limit protrusions to limit the pressing position and reset position of the pedal 41.

[0108] In this embodiment, to trigger the unlocking function of the locking shaft 43 while the user presses the pedal 41, a protrusion needs to be provided under the pedal 41. The protrusion is rigidly connected to the pedal 41 itself and is fixed to the floor cleaning device through the housing. The protrusion is in contact with the locking shaft 43. That is, when the protrusion part of the pedal 41 rotates and displaces under the influence of the external force of the pedal 41, it will drive the locking shaft 43 to rotate simultaneously, so as to unlock the floor cleaning device in a timely manner according to the user's pressing.

[0109] Specifically, in order to prevent the user from failing to press the pedal 41 due to too small friction when using the pedal 41, in the embodiment of the present invention, anti-slip grooves are provided on the upper side of the pedal 41, that is, the part where the user presses the pedal 41. The anti-slip grooves can be several, as long as they play an anti-slip role, and the number of anti-slip grooves is not limited here.

[0110] In addition, when the user implements the embodiment of the present invention, the user steps on the pedal 41 of the floor cleaning device with the toes, and the pedal 41 moves downward, driving the locking shaft 43 to rotate counterclockwise. The locking shaft 43 is fixedly connected to the connecting rod of the floor cleaning device by the protrusion of the locking part 45. When the locking shaft 43 rotates counterclockwise, the floor cleaning device is disengaged from the connecting rod. On the contrary, a return torsion spring is assembled on the locking shaft 43 and the rotating shaft 42 to facilitate the reset of the pedal 41 and the locking shaft 43.

[0111] In addition, for the entire floor cleaning device, through the embodiment of the present invention, it can be realized that during the use of the floor cleaning device by the user, the replacement and disassembly of the water tank assembly 1 can be achieved by stepping on the pedal 41, without manual unlocking operation, which increases the convenience and operability of user use.

[0112] The lower extension end face of the intake pipe 51 is provided with an intake hole 52. The intake pipe 51 is in a ring-shaped column shape. One end of the intake pipe 51 extends downward and protrudes from the lower surface of the water tank lower shell 12, and the other end of the intake pipe 51 extends upward and protrudes into the interior of the water tank upper shell 11.

[0113] The water tank upper shell 11 is provided with an upward recess corresponding to the part of the intake pipe 51. The recess is inserted into the upper extension end of the other end of the intake pipe 51 with a clearance fit, and the upper extension end face of the other end of the intake pipe 51 is not in contact with the bottom surface of the recess of the water tank upper shell 11.

[0114] The extended end face at the other end of the air inlet pipe 51 maintains a distance of less than 1 mm from the bottom surface of the recessed part of the upper water tank shell 11.

[0115] The extended end face at the other end of the air inlet pipe 51 maintains a distance of 0.5 mm from the bottom surface of the recessed part of the upper water tank shell 11.

[0116] An opening groove 55 is provided on the extended end face at the other end of the air inlet pipe 51. The depth of the opening groove 55 is less than the depth of the recessed part, which is used to increase the area of air entering the water tank body. At the same time, it prevents impurities in the water in the water tank body from blocking the air inlet pipe 51 or preventing the formation of a water film at the air inlet hole. The opening groove 55 can be arranged in a cross shape or in a symmetrical notch manner, or in a zigzag concave-convex shape, which will not be elaborated here.

[0117] The water passing channel 53 is arranged inside the edge of the lower surface of the lower water tank shell 12. The water passing channel 53 can be offset equidistantly corresponding to the shape of the edge of the lower surface of the lower water tank shell 12 and set as the main path, or further offset equidistantly inward to set multiple main paths, and the multiple main paths are connected by branch paths.

[0118] The water tank bottom cover 13 is provided with at least one through water outlet hole 54. The water passing tank is connected to the water outlet hole 54 through the water passing channel 53. The water passing channel 53 has a horizontal main path and a vertical branch path.

[0119] The water outlet holes 54 are evenly distributed along the horizontal main path of the water passing channel 53. The air inlet holes 52 are evenly distributed corresponding to the other horizontal main path of the water passing channel 53, or the air inlet holes 52 and the water outlet holes 54 are located at the same horizontal position along the horizontal main path of the water passing channel 53.

[0120] The air inlet holes 52 extend non-connectively through the water tank bottom cover 13 and are in contact with the upper surface of the water tank mop 18. The air inlet holes 52 are connected to the air inlet pipe 51.

[0121] The multiple air inlet holes 52 are connected to the air inlet pipe 51 through a triangular cross-section channel, or the multiple air inlet holes 52 are respectively connected to the air inlet pipe 51.

[0122] A water passing tank is formed by a local concave on the lower outer surface of the lower water tank shell 12. The water tank bottom cover 13 is concave corresponding to the position of the water passing tank to form a bottom cover water passing tank, so as to increase the cross-sectional area of the water passing channel 53 and thus improve the drainage capacity.

[0123] A plurality of through water tank holes 15 are provided on the lower surface of the lower water tank shell 12 corresponding to the position of the water volume control component. The water outlet holes 54 can be connected to the water tank holes 15 through the water passing channel 53 to discharge the water in the water tank body to the water tank mop 18.

[0124] The water tank mop 18 is made of an easily absorbent textile. The bottom end of the air inlet hole 52 is closely attached to the absorbent textile of the water tank mop 18. After the absorbent textile absorbs water, it expands and closes the air inlet hole 52.

[0125] Specifically, when the user uses the embodiment of the present invention, the floor cleaning device needs to be placed flat, and it is necessary to ensure that when the floor cleaning device is placed flat, the water in the water tank body will not overflow and cause pollution. A water tank body is provided for storing the cleaning water required for the mop in the floor cleaning device. Then, a water tank air inlet hole 52 is provided to connect the air pressure in the water tank body with the external atmospheric pressure, so that when the internal and external pressures are the same, the water in the water tank body only automatically sinks and wets the mop of the floor cleaning device under the action of gravity. Therefore, when the water tank air inlet hole 52 is blocked by the wet mop, the water tank air inlet hole 52 cannot obtain the external atmospheric pressure, so the water in the water tank will not drop to the mop of the floor cleaning device under the action of gravity, and the space in the water tank body forms a relatively vacuum state.

[0126] Optionally, a circular recess is provided in the upper part of the water tank body, and the circular recess is in clearance fit with the water tank air inlet channel to form an upper communication structure for inputting the air entering through the water tank air inlet hole 52 into the water tank body through the air inlet channel.

[0127] Specifically, the above-mentioned water tank body is used to hold cleaning water, and the water tank air inlet hole 52, as the key mechanism for whether the cleaning water stops sinking to the mop of the floor cleaning device, needs to have an upper communication structure with the water tank air inlet hole 52. The upper communication structure can be a gap not greater than 1 mm, which is integrally recessed and formed by the water tank body to avoid damage to the floor cleaning device when cleaning the floor. The gap between the water tank air inlet hole 52 with the upper communication structure and the water tank body is used to input the air entering through the water tank air inlet hole 52 into the water tank body.

[0128] In order to enable the air inhaled by the air inlet hole 52 to flow to the water tank body through the air passage, a gap 1 mm away from the top wall of the water tank body needs to be provided. This gap is a communication passage for circulating the air between the air passage and the water tank body to make the internal and external air pressures the same.

[0129] Optionally, a rubber sealing ring with the same outer diameter as the water tank air inlet hole 52 is installed at the bottom of the water tank air inlet hole 52 to prevent external air from entering the water tank air inlet hole 52 when closing the air.

[0130] Specifically, in order to make the water tank air inlet hole 52 in a sealed state except for the influence of the mop of the floor cleaning device when entering and exiting air, a rubber sealing ring can be installed at the bottom end of the water tank air inlet hole 52. This rubber sealing ring can be adhesively connected to the bottom end of the water tank air inlet hole 52 to prevent external air from entering the water tank air inlet hole 52 and causing incomplete water stoppage after the airtight effect is generated when the mop in the floor cleaning device is wet.

[0131] Optionally, the water tank air inlet hole 52 is in contact with the mop of the floor cleaning device.

[0132] Specifically, the mop of the floor cleaning device can be made of a water-absorbent fabric. The bottom of the water tank body is adhesively connected to the mop of the floor cleaning device through Velcro. Based on the above connection method, the air inlet of the water tank air inlet hole 52, that is, the bottom end of the water tank air inlet hole 52, forms a tightly fitting relationship with the mop of the floor cleaning device made of the above-mentioned water-absorbent fabric. Then, when the water-absorbent fabric absorbs water and expands, the air inlet of the water tank air inlet hole 52 is closed, achieving the technical effect of stopping water.

[0133] In addition, according to the implementation method of the embodiment of the present invention, when the knob switch of the water volume control module is in the large water or small water gear, and the external floor cleaning device is stationary and flat on the ground, the prerequisite is that the floor cleaning device is stationary and flat. When the user forgets to turn off the knob to stop the water flow, the water outlet hole 54 will continuously discharge water. For the water tank to discharge water, it is necessary for the outside to provide air to ensure that the air pressure in the water tank is the same as the outside air pressure. When the amount of water discharged from the water tank is large enough and wets the mop, the water on the mop will naturally close and seal the air inlet hole 52, so that the water tank cannot obtain the air pressure difference supply, thereby controlling the water tank body to stop discharging water within a certain period of time. Therefore, the function of the external floor cleaning device to stop water when placed flat is realized. In addition, according to the shrinkage and water absorption of the mop, it is ensured that the water volume will not overflow outside the mop during the water discharge of the water tank body, and the ground will not be polluted.

[0134] In addition, when the floor cleaning device is not in use, through the action of horizontal water stop and the air inlet hole, the user can block the water outlet hole 54 when hanging the mop to limit the continuous outflow of water in the water tank.

[0135] Specifically, at least one air inlet hole is convexly provided on the outer surface of the lower part of the water tank lower shell 12. The air inlet hole extends non-communicatively through the water tank bottom cover 13 and is in contact with the upper surface of the water tank mop 18. The air inlet hole is communicated with the air inlet pipeline 51. The air inlet hole and the air inlet pipeline 51 can be connected by a triangular cross-section channel with multiple air inlets or the air inlet holes are respectively communicated with the air inlet pipeline 51, which will not be further elaborated here.

[0136] The air inlet hole 52 is used for the water tank to inhale and close air. Therefore, the air inlet hole 52 controls whether the water in the water tank can reach the mop of the floor cleaning device. Then, the uniformly distributed air inlet holes 52 can accurately obtain the wetness of the mop. That is, only after all the air inlet holes 52 are closed, the outside air will not enter the water tank air inlet hole 52, and then a relatively vacuum environment is formed in the water tank body, so that the water in the water tank will not overflow due to hanging the floor cleaning device.

[0137] In order to make the air inlet holes more accurate in judging the dryness and wetness of the mop in the mopping module, multiple air inlet holes can be provided and evenly distributed at the bottom of the water tank body at the same time. Then, after the bottom of the water tank body adheres to the mop, all the air inlet holes will be in a closed or open state according to the dryness and wetness of the mop. Therefore, only when the mop is completely wetted is it possible to close all the air inlet holes, making the space in the water tank body in a relatively vacuum state and preventing the water in the water tank body from overflowing onto the mop, achieving a better water stop effect.

[0138] A plurality of through water tank holes 15 are provided on the lower surface of the water tank lower shell 12 corresponding to the position of the water volume control component. The water outlet holes 54 are evenly distributed along the horizontal main path of the water passing channel 53, the air inlet holes are evenly distributed along the other horizontal main path of the water passing channel 53, or the air inlet holes and the water outlet holes 54 are located at the same horizontal position along the horizontal main path of the water passing channel 53, and the horizontal positions of the air inlet holes and the water outlet holes 54 are both higher than the horizontal position of the water tank holes 15 of the water tank lower shell 12.

[0139] In addition, during the use of the embodiment of the present invention, when the external ground cleaning device is in a suspended state, no water will flow out from the water outlet holes 54 of the water passing channel 53 regardless of whether the water tank water volume control knob is in the large water or small water gear. The position of the water tank holes 15 is lower than the position of the water outlet holes 54. Due to the action of gravity, water will not flow upward to the water outlet holes 54 during the suspension process. At the same time, due to the action of the wet mop, the air in the water tank body is closed, achieving the effect of water stop.

[0140] In addition, during the process of suspending the ground cleaning device, the water volume of the water tank of the ground cleaning device is controlled through the action of the mop and the air inlet holes 52, so that the user can block the air inlet holes 52 when hanging the mop to limit the continuous outflow of water in the water tank. At the same time, when the mop lacks moisture, the mop is infiltrated by using structures such as the water outlet holes 54, achieving the technical effect of being able to clean the ground at any time.

[0141] Optionally, the water outlet holes 54 are evenly distributed at equal intervals on one side of the ground cleaning device. Among them, each hole position of the water outlet holes 54 is a perfect circle, and the center distance between each adjacent water outlet hole 54 is 1 cm.

[0142] Optionally, the air inlet holes 52 are evenly distributed at equal intervals on the other side of the ground cleaning device. Among them, each hole position of the air inlet holes 52 is a perfect circle, and the center distance between each adjacent water outlet hole 54 is 1 cm.

[0143] Specifically, in order to achieve the purpose of transmitting and closing the air pressure to the water tank body in the embodiments of the present invention, the exhaust pipeline is communicated with the water tank body, and the air inlet hole is located between the mop and the bottom of the water tank body, which is used to directly contact the mop, and inhale or close the air according to the dryness or wetness of the mop. Furthermore, the air passing through the air inlet hole and the air inlet pipeline 51 can also reach the water tank body through the communication passage. When the air inlet hole can inhale air, the air pressure in the water tank body is consistent with the external air pressure. At this time, the moisture in the water tank body can flow into the mop under the action of gravity to moisten the mop. However, when the mop is fully moistened, it will block the air inlet hole, so the air inhalation at the air inlet hole is closed, that is, no external air is inhaled. Then the air in the air duct and the water tank body will be in a relatively vacuum air pressure state, and the moisture in the water tank body will no longer flow out under the influence of gravity, that is, the moisture in the water tank body will be kept in the body according to the air closing situation, achieving the technical effect of water stoppage.

[0144] Through the above steps, the technical effect of automatically stopping water when the flat ground cleaning device is placed on the ground can be achieved. At the same time, when the mop lacks moisture, the mop can be wetted by using structures such as the water outlet hole, achieving the technical effect of being able to clean the ground at any time.

[0145] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0146] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
