When supplies or tools have automated components and save labor costs and time, the purpose of fully optimizing people's lives and production is achieved.

[0003] At present, when mopping the floor, the existing floor cleaning device often requires the user to actively place or remove the water tank, otherwise the stored water in the water tank will excessively soak the mop of the floor cleaning device, causing a large amount of water to overflow, pollute the floor, and even damage the wooden floor.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0005] The embodiment of the present invention provides a water tank assembly to at least solve the technical problem in the prior art that the water in the water tank of the mop module cannot be automatically stopped.

[0006] According to one aspect of an embodiment of the present invention, a water tank assembly is provided, which includes a water tank, a mop, and a water stopping device, wherein the water tank has a water tank hole, and the water stopping device includes a static water stopping component and / or a hanging water stopping component, the static water stopping component stops the water tank hole of the water tank assembly from discharging water in a static or quasi-static state, and the hanging water stopping component stops the water tank hole of the water tank assembly from discharging water when it is suspended.

[0007] Furthermore, the water tank assembly also includes a water tank bottom cover, and the water tank, the water tank bottom cover, and the mop are connected in sequence from top to bottom, and a water passage is formed between the water tank bottom cover and the water tank.

[0008] Furthermore, the static water-stopping component includes an air inlet pipe and an air inlet hole. The air inlet hole is arranged on the bottom cover of the water tank. The air inlet pipe and the water flow channel separate the water in the water tank. The mop absorbs water and expands to block the air inlet pipe, thereby stopping water from flowing through the water flow channel.

[0009] Furthermore, the air intake pipeline is arranged in the water tank, the air intake pipeline is connected to the air in the water tank, and the water passage is connected to the water in the water tank.

[0010] Furthermore, the air inlet hole is spaced a certain distance from the upper surface of the mop. In the water-stopping state, the mop surface blocks the air inlet hole. One or more radial grooves centered on the air inlet hole are arranged around the air inlet hole on the lower surface of the water tank bottom cover.

[0011] Furthermore, the air intake pipeline is fixedly arranged at the bottom of the water tank, one end of which extends to the inner upper wall of the water tank and is spaced a certain distance from the upper wall, and the other end of which extends into the bottom cover of the water tank and is connected to the air intake hole.

[0012] Furthermore, an upward recessed portion is provided on the inner upper wall of the water tank corresponding to the air intake pipe portion, the recessed portion is inserted and matched with one end of the air intake pipe in a clearance, and the end surface of the matching end of the air intake pipe is non-contacting with the bottom surface of the recessed portion.

[0013] Furthermore, the hanging water-stopping component includes a water outlet hole, the water outlet hole is connected to the water tank hole through the water passage, and the horizontal position at which the water outlet hole is suspended is higher than the horizontal position at which the water tank hole is suspended.

[0014] Furthermore, there is at least one water outlet hole, which is arranged through the bottom cover of the water tank. When the water tank assembly is hung, the highest point of the water passage is higher than each of the one or more water outlet holes.

[0016] In an embodiment of the present invention, an air intake pipe, an air intake hole, a water passage, and a water tank assembly are used, and an air pressure sealing effect is provided between the water tank air intake hole and the mop of the floor cleaning device, so that when the above-mentioned floor cleaning device is placed flat, the water in the water tank body will not overflow and cause pollution.

[0017] When the floor cleaning device is in a suspended state, no matter the water volume control knob is in the high or low water gear, water will not flow out of the water outlet of the water channel. Since the position of the water tank hole is lower than the water outlet and the air inlet, water will not flow up to the water outlet during the hanging process. At the same time, the air in the water tank body is closed due to the action of the wet mop, achieving the effect of hanging water stopping, and the water in the water tank body will not overflow and cause pollution.

[0018] One end of the air intake pipe is in contact with the upper surface of the water tank mop, and the other end of the air intake pipe is not in contact with the upper inner surface of the water tank upper shell.

[0040] The water tank assembly includes an upper water tank shell 11, a lower water tank shell 12, a bottom water tank cover 13, and a water tank mop 18. The upper water tank shell 11 and the lower water tank shell 12 are snap-fitted and sealed to form a hollow water tank body. The bottom water tank cover 13 is detachably mounted on the lower outer surface of the lower water tank shell 12, and the water tank mop 18 is detachably mounted on the lower surface of the bottom water tank cover 13.

[0041] An air intake hole 52 is provided on the lower extended end surface of the air intake pipeline 51 . The air intake pipeline 51 is an annular column. One end of the air intake pipeline 51 extends downward to protrude from the lower surface of the water tank lower shell 12 , and the other end of the air intake pipeline 51 extends upward to protrude into the interior of the water tank upper shell 11 .

[0042] The water tank upper shell 11 is provided with an upward recessed portion corresponding to the air intake pipe 51 , and the recessed portion is inserted and matched with the upper extension end of the other end of the air intake pipe 51 , and the upper extension end surface of the other end of the air intake pipe 51 is non-contacting with the bottom surface of the recessed portion of the water tank upper shell 11 .

[0043] The extended end surface at the other end of the air intake pipe 51 maintains a distance of less than 1 mm from the bottom surface of the recessed portion of the water tank upper shell 11 .

[0044] The extended end surface at the other end of the air intake pipe 51 maintains a distance of 0.5 mm from the bottom surface of the recessed portion of the water tank upper shell 11 .

[0045] An open groove 55 is provided on the extended end surface at the other end of the air intake pipe 51. The depth of the open groove 55 is less than the depth of the recessed portion, which is used to increase the area for air to enter the water tank body, while preventing impurities in the water in the water tank body from blocking the air intake pipe 51 or preventing a water film from forming at the air intake hole. The open groove 55 can be in a cross shape or in the form of symmetrical notches, or can be set in a serrated shape, which will not be described in detail here.

[0046] The water passage 53 is arranged inside the edge of the lower surface of the water tank lower shell 12. The water passage 53 can be set as a main road at an equidistant offset corresponding to the shape of the lower surface edge of the water tank lower shell 12, or multiple main roads can be further set at an equidistant offset inward, and the multiple main roads are connected by branches.

[0047] The water tank bottom cover 13 is provided with at least one water outlet hole 54 which passes through the water tank. The water channel 53 is connected to the water outlet hole 54 through the water channel. The water channel 53 has a horizontal main path and a vertical branch path.

[0048] The water outlet holes 54 are evenly distributed along one or more horizontal main paths of the water passage 53 , and 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 passage 53 .

[0049] The air inlet hole 52 extends through the water tank bottom cover 13 without being connected, and contacts the upper surface of the water tank mop 18 . The air inlet hole 52 is connected to the air inlet pipeline 51 .

[0050] There are multiple air inlet holes 52 , and the multiple air inlet holes 52 are connected to the air inlet pipeline 51 through a triangular cross-section channel, or the air inlet holes are connected to the air inlet pipeline 51 respectively.

[0051] The lower outer surface of the water tank lower shell 12 is partially concave to form a water groove, and the water tank bottom cover 13 is concave corresponding to the position of the water groove to form a bottom cover water groove, so as to increase the cross-sectional area of ​​the water passage 53, thereby increasing the drainage volume.

[0052] A plurality of through water tank holes 15 are arranged on the lower surface of the water tank lower shell 12 corresponding to the position of the water volume control assembly. The water outlet holes 54 can be connected to the water tank holes 15 through the water passage 53 to discharge the water in the water tank body to the water tank mop 18 .

[0053] The water tank mop 18 is made of a water-absorbent textile. The bottom end of the air inlet 52 is tightly fitted with the water-absorbent textile of the water tank mop 18 . The water-absorbent textile expands after absorbing water and closes the air inlet 52 .

[0054] Specifically, when using the embodiment of the present invention, the user needs to lay the floor cleaning device flat, and when the floor cleaning device is laid flat, the water in the water tank body will not overflow and cause pollution. A water tank body is provided to store the cleaning water required for the mop in the floor cleaning device, and then a water tank air inlet 52 is provided to connect the air pressure in the water tank body with the external atmospheric pressure, so that when the internal pressure and the external pressure are the same, the water in the water tank body automatically sinks and wets the mop of the floor cleaning device only under the action of gravity. Therefore, when the water tank air inlet 52 is blocked by the wet mop, the water tank air inlet 52 cannot obtain the external atmospheric pressure, so the water in the water tank will not fall into the mop of the floor cleaning device under the action of gravity, and the space in the water tank body also forms a relatively vacuum state.

[0055] Optionally, a circular recess is provided on the upper portion of the water tank body, and the circular recess cooperates with the clearance of the water tank air inlet channel to form an upper connecting structure for inputting the air entering through the water tank air inlet hole 52 into the water tank body through the air inlet channel.

[0056] Specifically, the water tank body is used to hold cleaning water, and the water tank air inlet 52 is a key mechanism for determining whether the cleaning water stops sinking into the mop of the floor cleaning device. It is necessary to form an upper connecting structure with the water tank air inlet 52. The upper connecting structure can be a gap of no more than 1 mm, which is formed by an integral concave shape through the water tank body to prevent the floor cleaning device from being damaged when cleaning the floor. The gap between the water tank air inlet 52 of the upper connecting structure and the water tank body is used to input the air entering the water tank air inlet 52 into the water tank body.

[0057] In order to allow the air sucked in from the air inlet hole by the air intake pipe 51 to flow to the water tank body through the air duct, it is necessary to set a gap of 1 mm from the top wall of the water tank body. The gap is a connecting passage for circulating the air in the air duct and the water tank body to make the internal and external air pressures the same.

[0058] 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 outside air from entering the water tank air inlet hole 52 when the air is closed.

[0059] 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 the air enters and exits, a rubber sealing ring can be installed at the bottom of the water tank air inlet hole 52. The rubber sealing ring can be adhesively connected to the bottom of the water tank air inlet hole 52, and is used to prevent outside air from entering the water tank air inlet hole 52 after the air-locking effect is produced when the mop is wetted in the floor cleaning device, resulting in incomplete water stopping.

[0060] Optionally, the mop of the floor cleaning device is bonded to the bottom of the water tank body by Velcro, wherein the Velcro is a square sticker of double-sided adhesive material.

[0061] Optionally, the water tank air inlet hole 52 and the mop of the floor cleaning device are in contact with each other.

[0062] Specifically, the mop of the floor cleaning device can be made of a textile that is easy to absorb water, and the bottom of the water tank body is bonded and 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 close fit with the mop of the floor cleaning device made of the above-mentioned water-absorbing textile, and then when the water-absorbing textile expands after absorbing water, it closes the air inlet of the water tank air inlet hole 52, thereby achieving the technical effect of stopping water.

[0063] 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 high water or low water gear, the external floor cleaning device is placed flat on the ground, and the prerequisite is that the floor cleaning device is placed flat on the ground. In the case that the user forgets to turn off the knob to discharge water, the water outlet 54 will continue to discharge water. The water discharge of the water tank requires air from the outside to ensure that the air pressure in the water tank is consistent with the outside air pressure. When the amount of water discharged from the water tank is large enough and wets the mop, the water in the mop will naturally close and seal the air inlet 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, thereby realizing the function of stopping water when the appearance of the floor cleaning device is placed flat. 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 will not cause ground pollution.

[0064] In addition, when the floor cleaning device is not in use, through the effect of the 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.

[0065] Specifically, at least one air inlet hole is protruding from the lower outer surface of the water tank lower shell 12, and the air inlet hole extends non-connectedly through the water tank bottom cover 13 and contacts the upper surface of the water tank mop 18. The air inlet hole is connected to the air inlet pipe 51, which will not be further described here.

[0066] The air inlet holes 52 are used to inhale and close air through the water tank. Therefore, the air inlet holes 52 control whether the water in the water tank can reach the mop of the floor cleaning device. Then, the 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 air inlet holes 52 of the water tank will not enter the outside air, thereby forming a relatively vacuum environment in the water tank body, so that the water in the water tank will not overflow due to the hanging floor cleaning device.

[0067] In order to make the air inlet holes judge the wetness of the mop in the mopping module more accurately, multiple air inlet holes can be set and evenly distributed on the bottom of the water tank body. Then, when the mop is stuck to the bottom of the water tank body, all the air inlet holes will be closed or open according to the wetness of the mop. Therefore, only when the mop is completely wetted can all the air inlet holes be closed, so that the space in the water tank body is in a relative vacuum state, and the water in the water tank body will not overflow onto the mop, thereby achieving a better water-stopping effect.

[0068] A plurality of through water tank holes 15 are arranged 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 road of the water passage 53, the air inlet holes 52 are evenly distributed along another horizontal main road of the water passage 53, or the air inlet holes and the water outlet holes 54 are located at the same horizontal position along the horizontal main road of the water passage 53, and the horizontal positions of the air inlet holes 52 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.

[0069] In addition, during use of the embodiment of the present invention, when the external floor cleaning device is in a suspended state, no matter the water volume control knob of the water tank is in the high water or low water gear, water will not flow out of the water outlet 54 of the water passage 53. As shown in the figure, the position of the water tank hole 15 is lower than the position of the water outlet 54. Due to the effect of gravity, water will not flow up to the water outlet 54 during the hanging process. At the same time, the air in the water tank body is closed due to the action of the wet mop, thereby achieving the effect of water stopping.

[0070] In addition, during the process of hanging the floor cleaning device, the amount of water in the water tank of the floor cleaning device is controlled through the action of the mop and the air inlet 52, so that the user can block the air inlet 52 when hanging the mop to limit the continuous outflow of water in the water tank. At the same time, when the mop lacks water, the water outlet 54 and other structures are used to soak the mop, thereby achieving the technical effect of being able to clean the floor at any time.

[0071] Optionally, the water outlet holes 54 are evenly distributed on one side of the floor cleaning device, wherein each hole of the water outlet holes 54 is a perfect circle, and the center distance between each adjacent water outlet hole 54 is 1 cm.

[0072] Optionally, the air inlet holes 52 are evenly distributed on one side of the floor cleaning device, wherein each hole of the air inlet hole 52 is a perfect circle, and the center distance between each adjacent water outlet hole 54 is 1 cm.

[0073] Specifically, in order to achieve the purpose of transmitting and closing air pressure to the water tank body, the embodiment of the present invention communicates with the water tank body, and the air inlet 52 is located between the mop and the bottom of the water tank body, for directly contacting the mop, and sucking in or closing air according to the dryness or wetness of the mop, and then the air entering the air inlet 51 through the air inlet 52 can also reach the water tank body through the connecting passage. When the air inlet can suck in air, the air pressure in the water tank body is consistent with the outside air pressure. At this time, the moisture in the water tank body can flow into the mop under the action of gravity to wet the mop. However, when the mop is fully wetted, it will block the air inlet, so that the air inlet out of the air inlet is closed, that is, no outside air is sucked in, then the air in the airway and the water tank body will be in a relatively vacuum pressure state, then the moisture in the water tank body will no longer be affected by gravity and flow out, that is, the moisture in the water tank body will be kept in the body according to the air closing condition, thereby achieving the technical effect of water stopping.

[0074] Through the above steps, the technical effect of automatically stopping water when the floor cleaning device is placed flat can be achieved. At the same time, when the mop lacks water, the mop can be soaked by using structures such as water outlets, so as to achieve the technical effect of being able to clean the floor at any time.

[0075] According to another aspect of an embodiment of the present invention, a floor cleaning device is provided, which includes the above-mentioned water-stopping device, and the floor cleaning device also includes a water tank assembly 1, a water volume control knob assembly 2, a mop cleaning assembly 3, and a pedal linkage assembly 4. The mop cleaning assembly 3 is arranged at one end of the upper part of the water tank assembly 1, and the water volume control knob assembly 2 and the pedal linkage assembly 4 are symmetrically arranged on both sides of the other end of the water tank assembly 1. The water-stopping device is arranged in the water tank assembly 1.

[0076] The water tank body is used to store water, so the upper shell and the lower shell of the water tank are rigidly and waterproofly connected, and the joints can be formed by bonding or hot pressing. The specific connection method is not specifically limited here.

[0077] In the water volume control knob assembly 2, an annular columnar water tank lower bracket 14 is integrally provided on the lower inner surface of the water tank lower shell 12, and a plurality of through water tank holes 15 are provided on the bottom shell of the water tank lower shell 12 near the water tank lower bracket 14. The knob rod 23 is rotatably penetrated in the water tank lower shell 12, and the knob rod 23 can be rotated through the knob upper cover 21. An annular water control disk is integrally provided on the outer side surface of the lower end of the knob rod 23, and the annular water control disk is provided with through water control holes 24. The water control holes 24 are used to adjust the water volume by cooperating with the water tank holes 15.

[0078] There are two water tank holes 15, which are distributed along the circumference of the water tank lower bracket 14, respectively corresponding to two different gear position identification positions, and the two water tank holes 15 have different cross-sectional areas. Preferably, the cross-sectional area of ​​the second water tank hole 15 is 2 to 4 times the cross-sectional area of ​​the first water tank hole 15. The side wall recesses of the rotary accommodating tank are symmetrically arranged, respectively arranged at the positions corresponding to each gear position identification, and the cross-sectional area of ​​the water control hole 24 is greater than or equal to the cross-sectional area of ​​the second water tank hole 15.

[0079] The lower outer surface of the water tank lower shell 12 is partially concave to form a water groove, and the water tank bottom cover 13 is detachably installed on the lower outer surface of the water tank lower shell 12, and a water passage is formed between the water tank bottom cover 13 and the water groove. The annular water control disk of the knob rod 23 is located in the water passage, and the annular water control disk can rotate and move up and down in the water passage.

[0080] The knob cover 21 rotates, causing the rigidly fixed knob rod 23 to rotate to rotate the annular water control disk at the lower end of the knob rod 23, thereby causing the water control hole 24 of the annular water control disk to displace circumferentially with the rotational motion. When the knob is located at the zero gear mark, the water control hole 24 is not connected to any water tank hole 15. When the knob is located at the first gear mark, the water control hole 24 is connected to the first water tank hole 15.
