Referring to fig. 1 to 5, a centrifugally drainable mop assembly includes: a water storage tank 1; the water outlet plate 2 is communicated with the water storage tank 1, and a centrifugal water outlet structure 5 is arranged on the water outlet plate 2; the mop plate 3 is connected with the water outlet plate 2; and a pressurizing device 4 for pressurizing the water in the water storage tank 1, wherein when the water flows through the centrifugal water outlet structure under the pressurizing action of the pressurizing device 4, the flow speed of the water flow in the circumferential direction is increased under the centrifugal action of the centrifugal water outlet structure 5. The principle of the scheme is as follows: under the condition that the centrifugal water outlet structure 5 is filled with liquid, the centrifugal water outlet structure 5 rotates to generate centrifugal force, and the liquid is thrown to the periphery under the action of the centrifugal force. Because the range that the water can spray is correlated with the initial velocity when the water flows out, the liquid obtains great speed when being thrown to the periphery under the effect of centrifugal force, therefore can make the mop wet on a large scale. In addition, the centrifugal water outlet structure 5 forms a vacuum at the center thereof, and water flows into the centrifugal water outlet structure 5 from the water storage tank 1 under the action of the pressurizing device 4. Thus, water is continuously sucked and pumped out, and the humidifying effect on the mop is accelerated. In one possible embodiment, the centrifugal water outlet structure is a driving device 51 and a cylinder connected to the output of the driving device 51. The interior of the cylinder is hollow, the interior of the cylinder is communicated with the water storage tank 1, a plurality of holes are formed in the peripheral side wall of the cylinder, the rotation of the cylinder is driven by the driving device 51, and the principle of the cylinder is approximately similar to that of a dewatering cylinder of a washing machine. The water in the water storage tank 1 enters the cylinder, the water in the cylinder is thrown to the periphery from the center of the cylinder under the action of high-speed centrifugation, and when the water reaches the holes in the peripheral side wall of the cylinder, the flow rate of the water is increased and is thrown out of the cylinder, so that the range of water spraying the mop plate 3 is enlarged. And because the holes on the peripheral side wall of the cylinder are uniformly distributed from top to bottom, under the condition of obtaining the same initial speed, the water flowing out from the holes with higher height falls on the mop cloth at a distance far away from the water supply, and the water flowing out from the holes with lower height falls on the mop cloth at a distance near from the water supply, so the embodiment can realize the effect that the water is uniformly sprayed on the mop cloth. The present embodiment only lists some possible situations of the centrifugal water outlet structure 5, and other ways to achieve the same centrifugal function are also included in the scope covered by the claims of the present invention.

Specifically, the aqua storage tank 1 in this embodiment is arranged on one side of the interior of the mop component, the aqua storage tank 1 is provided with a water adding hole for adding water into the aqua storage tank 1, a sealing plate is arranged on the water adding position cover, and the sealing plate and the sealing ring are matched to improve the sealing performance in the aqua storage tank 1. The other side in the mop component is provided with a pressurizing device 4. The apopore that communicates with extending structure is seted up to the bottom of aqua storage tank 1, and pressure device 4 pressurizes the water in the aqua storage tank 1, makes water flow to 5 departments of centrifugal play water structure from the apopore, is carried out the humidification to the mopping board by centrifugal play water structure 5. Go out and be formed with the recess on the water board 2, be formed with the flange with recess looks adaptation on the mop board 3, the flange joint is in the recess, makes to form the water route that can supply rivers to pass through between water board 2 and the mounting panel 31, and centrifugation goes out water structure and water route intercommunication. The way in which the water path is formed between the outlet plate 2 and the mounting plate 31 may take many forms. For example, the mop assembly is provided with a bottom plate at the bottom, and the bottom plate and the water outlet plate 2 are integrally formed. A gap is reserved between the bottom plate and the mop plate 3, a surrounding plate is arranged between the gaps, and a waterway for communicating the water storage tank 1 with the mop plate 3 is formed among the bottom plate, the mop plate and the surrounding plate. This mode production degree of difficulty is higher, is unfavorable for the assembly. In a preferred embodiment, the mop plate 3 is provided with a flange, the bottom plate is provided with a groove matched with the flange, and the flange is clamped in the groove, so that a waterway is formed between the mounting plate 31 and the bottom plate. So set up, reduced the production bottom plate and the mounting panel 31 production degree of difficulty, the assembly of being convenient for, moreover through flange joint in the recess, also formed the water route when realizing bottom plate and mounting panel 31 fixed connection.

Specifically, the centrifugal water outlet structure 5 comprises a driving device 51 and a rotating part arranged at the output end of the driving device 51, when the driving device 51 is started, the rotating part is driven by the driving device 51 to rotate, work is applied to water flowing through the rotating part, the water is thrown to the periphery from the center of the rotating part under the centrifugal action, and when the water reaches the periphery of the rotating part, the flow rate of the water is increased, so that the range of spraying the mop plate 3 with the water is enlarged. Specifically, in the absence of the surge tank 57, although the centrifugal outflow structure 5 can achieve the effect of enlarging the spraying range by increasing the flow rate of water, since the flow rate of water is constant, the range in which the mop can be reached is also constant, which may result in a situation where the surroundings near the centrifugal outflow structure 5 are not sprayed. The water enters the water homogenizing cylinder 57 after being accelerated by the centrifugal water outlet structure 5, the water in the water homogenizing cylinder 57 is subjected to higher pressure, and when the water reaches the holes on the peripheral side wall of the cylinder, the flow rate of the water is increased and is extruded out of the water homogenizing cylinder 57, so that the aim of expanding the range of spraying the water on the mop plate 3 is achieved. And because the holes on the peripheral side wall of the water homogenizing cylinder 57 are uniformly distributed from top to bottom, under the condition of obtaining the same initial speed, the water flowing out from the holes with higher height falls on a point far away from the water feeding distance of the mop, and the water flowing out from the holes with lower height falls on a point near the water feeding distance of the mop, therefore, the effect of uniformly spraying the water on the mop can be realized.

In another possible embodiment, the rotating member comprises a hub 52 provided at the output end of the driving device 51, and blades 53 circumferentially distributed around the hub 52. In the present embodiment, the connection manner of the blades 53 and the hub 52 has various forms. In one way, the blades 53 can be directly connected to the hub 52, and the hub 52 can rotate the blades 53. The blades 53 generate dynamic loads when rotating, and both centrifugal force and drag force are transmitted to the hub 52 through the root of the blades 53, thereby damaging the structure of the hub 52. Conventionally, the strength of the hub 52 is improved to some extent by adding ribs inside the hub 52 to increase the strength of the hub 52, but there is still a case where the internal stress cannot be released. In addition, in the related art, the strength of the hub 52 is improved by thickening the reinforcing ribs, so that the risk of shrinkage and deformation of the product is increased, other performance indexes of the product are further influenced, and factors such as poor stability, harsh production process conditions and the like are generated. Furthermore, when it is desired to increase the speed of the water, two ways are possible. Firstly, the power of the driving device 51 is increased to increase the rotating speed, so that the water obtains higher speed; secondly, the distance between the outermost edge of the blade 53 and the hub 52 is increased to obtain higher speed of water, but the distance between the outermost edge of the blade 53 and the hub 52 is increased to increase the area of the blade 53, so that the contact area between the blade 53 and the water is increased, the resistance is increased, and higher requirements are provided for the hub strength of the hub 52. In a preferred form, therefore, the rotating member further includes a bottom wall 54 connected to the outer peripheral surface of the hub 52, the vanes 53 are circumferentially distributed on the bottom wall 54, the upper surface of the bottom wall 54 is connected to the bottoms of the vanes 53, and a gap is reserved between the vanes 53 and the hub 52. In this embodiment, the blades 53 are not directly connected to the hub 52, so that it is not necessary to add a reinforcing rib inside the hub 52 to enhance the strength of the hub 52. In addition, since the vane 53 is directly connected to the bottom wall 54, the size of the vane 53 can be selected more, and the distance between the outermost edge of the vane 53 and the hub 52 can be increased while the area of the vane 53 can be reduced appropriately to reduce the resistance. In addition, since a gap is left between the blade 53 and the hub 52, water can be more easily sucked into the rotating member and thrown to the outside by the blade 53. Therefore, the blades 53 are circumferentially distributed on the bottom wall 54, which reduces the strength requirement of the hub 52 and makes the water flow more smooth.

Further, the rotating member further includes a fixing ring 55 coaxial with the hub 52, and a lower surface of the fixing ring 55 is connected to the tops of the plurality of blades 53. Under the resistance of water, the resistance of the blade 53 is concentrated on the joint of the bottom of the blade 53 and the bottom wall 54, and the resistance of the top of the blade 53 is the largest, and the influence on the joint is the largest. Therefore, the junction of the bottom of the vane 53 and the bottom wall 54 is most easily damaged. The provision of the fixing ring 55 allows the bottom and top of the blade 53 to be balanced in terms of force, while providing the blade 53 with greater stability during rotation.

In a feasible embodiment, the water outlet plate 2 is provided with a flow guide channel 56 for communicating the water storage tank 1 with the centrifugal water outlet structure 5, the flow guide channel 56 comprises a water inlet 561 and a water outlet 562, the water inlet 561 is funnel-shaped, and an opening at an upper end of the water inlet 561 is larger than an opening at a lower end of the water inlet. Since the water in the centrifugal outlet structure 5 is accelerated by the centrifugal action of the blades 53, a funnel-shaped water inlet 561 is needed to increase the flow of water into the rotating member.

In a preferred embodiment, referring to fig. 4, a baffle 563 is formed at the bottom of the water outlet plate 2 corresponding to the position of the water outlet 562, and the lower end of the baffle 563 is lower than the upper surface of the fixing ring 55. Because the fixed ring 55 and the bottom of the water outlet plate 2 have a gap, the rotating part is prevented from being abutted against the bottom of the water outlet plate 2 when the driving device 51 drives the rotating part to rotate, and the rotating part is prevented from being blocked. For the above reasons, when water flows through the centrifugal water discharge mechanism, the water flows out from the gap between the upper surface of the fixing ring 55 and the bottom of the water discharge plate 2. The water flowing out of the gap between the upper surface of the fixed ring 55 and the bottom of the water outlet plate 2 overflows to the outer peripheral side of the blades 53 in the same direction as the axial direction of the hub 52. At the same time, the water accelerated by the blades 53 is thrown in the radial direction of the hub 52. Two rivers that the direction is different collide each other, and the water of radial direction slows down at the water of axial direction's blocking, and the speed of water has reduced the scope that sprays the mop like this, greatly reduced humidification efficiency. Therefore, when the outlet 562 extends downward to form a baffle 563, the lower end of the baffle 563 is lower than the upper surface of the fixing ring 55. Water can flow only into the center of the rotary member by the guide plate 563 without overflowing to the outer peripheral side of the vane 53. It is also ensured that the water from the guide passage 56 is accelerated by the rotary member, and the efficiency of converting the power of the driving means 51 into the flow rate of the water is improved.

In one possible embodiment, the water homogenizing cylinder 57 is arranged on the lower surface of the water outlet plate, and the driving device 51 is arranged on the bottom surface of the water homogenizing cylinder 57. In the present embodiment, the driving device 51 may be provided on the outer bottom surface of the water uniforming cylinder 57 or on the inner bottom surface of the water uniforming cylinder 57.

Further, the water homogenizing channel 571 is arranged in an inclined manner, and the height of one end of the water homogenizing channel located on the inner side wall of the water homogenizing cylinder 57 is higher than that of the other end of the water homogenizing channel located on the outer side wall of the water homogenizing cylinder 57. Since the mop plate is disposed below the centrifugal water outlet structure 5, if the water homogenizing channel 571 is opened obliquely upward, the water has a high initial speed, but a part of kinetic energy is consumed under the influence of gravity, and the speed is slowed down, resulting in a decrease in spraying efficiency. Therefore, the inclined downward arrangement enables the water to have the acceleration effect of the initial speed and the gravity, the spraying range is wider, and meanwhile, the water can smoothly flow to the mop cloth conveniently.

Further, the vane 53 has an arc structure, and the arc structure is recessed in a direction opposite to a direction in which the vane 53 rotates. The arc structure makes blade 53 and the one side that the water collided each other for streamlined and smooth and regular surface, does not have big fluctuation and sharp-pointed edges and corners, makes the resistance that blade 53 received at rotatory in-process less for water can flow out along the tangential direction of arc structure, obtains higher water velocity, also improves the life of blade through the resistance that reduces blade 53 and receive simultaneously.

Furthermore, the mop plate 3 includes a mounting plate 31 and a mop 32 connected to the mounting plate 31, a guide wall 311 is formed on the mounting plate 31 at a position corresponding to the centrifugal water outlet structure, and an inner side of the guide wall 311 is an inclined surface inclined downward from the center to the periphery. The inclined surface of the guide wall 311 can smoothly guide the sprayed water to fall on the mop. The mop cloth 32 is connected to the mounting plate 32 by a hook and loop fastener. The connection mode is simple, low in price and very practical.

Further, the centrifugal water outlet structure 5 is provided with a plurality of centrifugal water outlet structures, and the centrifugal water outlet structures are uniformly arranged along the flowing direction of water. Specifically, in this embodiment, centrifugation play water structure 5 has three, further adds water to the mop on a large scale, improves the humidification effect greatly, improves mop work efficiency.

In the present embodiment, since the driving device 51 is in contact with water for a long time, it is preferable that the driving device 51 is a waterproof motor, and a motor lead is connected to the bottom of the waterproof motor. This embodiment is only for the possible case of the driving device 51, and other ways to achieve the same driving function are also included in the scope of the claims of the present invention

In this embodiment, the pressurizing device 4 is an air pump or a water pump. The present invention is only illustrative of some possible cases of the pressurizing means 4, and other ways of achieving the same pressurizing function are also included in the scope of the present invention.
