[0034] Embodiment 1

[0035] The following is a reference to Figures 1 to 7 Describe a floor washer according to an embodiment of the present utility model, including an upper body 1, a water tank 2 and a lower body 3, and the water tank 2 is installed between the upper body 1 and the lower body 3; as Figure 1 shown, there is a floor washer main body between the upper body 1 and the lower body 2, and the water tank 2 is installed between the upper body 1 and the lower body 3, on the side of the floor washer main body. After the water tank is completely installed, the whole floor washer is formed. In this embodiment, taking the clean water tank in the floor washer as an example, an adjustment cover plate 4 is provided on the side wall of the upper body 1, and the adjustment cover plate 4 rotates along the rotation shaft 410. A connecting member 5 is provided between the adjustment cover plate 4 and the upper body 1. The rotation shaft 410 is of an integral or split structure. The connecting member 5 is fixed on a part of the rotation shaft 410. The connecting member 5 is fixed on the rotation shaft 410. One end of the connecting member 5 extends below the rotation shaft 410, and the other end is connected to the upper body 1. When the adjustment cover plate 4 rotates along the rotation shaft, since one end of the connecting member 5 extends below the rotation shaft 410, the rotation of the adjustment cover plate 4 generates a certain pressure on the connecting member 5. The other end of the connecting member 5 is connected to the upper body 1, so a reaction force will be generated on the connecting member 5. And because the connecting member 5 is fixed on the rotation shaft 410, when the adjustment cover plate 4 rotates along the rotation shaft 410, it will drive the rotation shaft 410 to displace. The rotation shaft 410 is away from the axis of the floor washer relative to both ends of the adjustment cover plate 4. The movement direction of the rotation shaft 410 is opposite to the movement direction of both ends of the adjustment cover plate 4. Both ends of the adjustment cover plate 4 are connected to the buckle structure 6. The buckle structure 6 is vertically arranged. A buckle groove 7 is opened at the top of the water tank 2. The position of the buckle groove 7 is matched with the buckle structure 6. Therefore, when the rotation shaft 410 displaces, it will drive the buckle structure 6 to displace.

[0036] It should be noted that in actual application, when installing the water tank, the water tank is directly put in until the buckle groove 7 is matched with the buckle structure 6 to achieve fixation; when disassembling the water tank, by pressing and rotating the adjustment cover plate 4, the adjustment cover plate 4 rotates towards the inside of the floor washer. When the adjustment cover plate 4 rotates inwards, an upward pressure will be generated. Since the connecting member 5 extends below the rotation shaft 410, the upward pressure will be transmitted to one end of the connecting member 5. The other end of the connecting member 5 generates a downward stress relatively. The rotation shaft 410 moves downward. Since the rotation shaft 410 is away from the axis of the floor washer relative to both ends of the adjustment cover plate 4 and the movement direction of the rotation shaft 410 is opposite to the movement direction of both ends of the adjustment cover plate 4, both ends of the adjustment cover plate 4 drive the buckle structure 6 to move upward. After the buckle structure 6 is disengaged from the buckle groove 7 of the water tank 2, the water tank 2 is removed.

[0037] In one embodiment, refer to Figure 1, openings are provided on both sides of the upper body 1. The adjustment cover plate 4 is installed at the opening position and covers the opening. The rotation direction of the adjustment cover plate 4 is the inside-outside direction of the floor washer. Using the adjustment cover plate 4 as the opening cover of the floor washer opening, no additional structure is installed on the surface of the floor washer, which can keep the appearance of the floor washer beautiful. In addition, the opening also provides a rotation space for the adjustment cover plate 4, facilitating people's use.

[0038] In one embodiment, the middle part of the connecting piece 5 is wound around the rotating shaft 410 for connecting and fixing with the adjustment cover plate 4. One end of the connecting piece 5 extending below the rotating shaft 410 is provided with a bend to increase the contact surface between the adjustment cover plate 4 and the connecting piece 5. In practical applications, the connecting piece 5 can be a metal strip.

[0039] In one embodiment, referring to Figure 2 , the adjustment cover plate 4 includes a cover body 420 and a snap connector 430. The cover body 420 and the snap connector 430 intersect at the rotating shaft 410. The setting directions of the cover body 420 and the snap connector 430 are different. The cover body 420 fits the opening of the upper body 1. In this embodiment, the cover body 420 can extend downward, and the snap connector 430 is placed horizontally. And the connection position of the snap connector 430 and the cover body 420 is far from the axis of the floor washer relative to both ends of the snap connector 430. Since the connection position of the snap connector 430 and the cover body 420 is flush with the rotating shaft 410, and the connecting piece 5 is connected to the upper body 1 on the rotating shaft 410, the movement direction of the rotating shaft 410 is opposite to the movement directions of both ends of the snap connector 430. When the rotating shaft 410 moves downward, the snap connector 430 drives the snap structure 6 to move upward.

[0040] In one embodiment, one end of the connecting piece 5 extends to the inside of the cover body 420. Therefore, the user can rotate the cover body 420 by pressing the cover body 420, driving the connecting piece 5 to move upward, and further realizing the upward movement of the snap structure 6 to separate the water tank 2 from the floor washer main body.

[0041] In one embodiment, referring to Figure 3 , one end of the snap structure 6 is provided with a partial opening. One end of the snap connector 430 extends into the opening. The caliber of the opening part is not greater than the maximum diameter of the snap connector 430, facilitating the disassembly and assembly between the snap structure 6 and the snap connector 430, and preventing the snap structure 6 from falling off the rotating shaft 410. Further, the front edge position of the opening of the snap structure 6 extends downward to avoid the opening being too large, and an inwardly extending barb is provided at the front edge position to further prevent the snap structure 6 from falling off.

[0042] It should be noted that referring to Figures 4 to 5, when installing the water tank 2, the buckle structure 6 faces downward, and the lower end of the buckle structure 6 extends into the buckle groove 7 of the water tank 2. The buckle connecting piece 430 is in a horizontal state in the groove of the buckle structure 6. Referring to the figure, when disassembling the water tank 2, the buckle structure 6 faces upward, the lower end of the buckle structure 6 disengages from the buckle groove 7, and the buckle connecting piece 430 is in a lifted state in the groove of the buckle structure 6. Further, in the embodiment, in order to prevent the buckle structure 6 from colliding with the buckle groove 7, the lower end of the buckle structure 6 is provided with a certain arc.

[0043] Further, two water filling holes are provided at the top and side of the water tank 2. The orientations of the two water filling holes are respectively consistent with and perpendicular to the placement direction of the water tank 2. When the water tank 2 is installed on the floor washer, the water filling hole at the top of the water tank 2 is blocked, and the user can add water through the water filling hole located on the side of the water tank 2. When the water tank 2 is disassembled, the user can add water to the water tank 2 from two positions, the top or the side of the water tank 2. The setting of the water filling hole can meet most water filling scenarios, improve the user experience, and by setting the water filling hole on the side of the water tank 2, it is not necessary to remove the water tank 2 from the floor washer when adding water to the water tank 2, saving the water filling steps and also avoiding the problems of difficult handling and installation when the water tank 2 is full of water.

[0044] In one embodiment, referring to Figure 6 and 7 , a convex structure 8 is provided at the bottom of the water tank 2, and a groove 9 matching the convex structure 8 is provided on the lower body 3. During installation, the convex structure 8 can position the installation of the water tank 2, improving the stability of the water tank 2 during use.

[0045] In one embodiment, there are multiple convex structures 8, and a water outlet hole is provided on one of the convex structures 8. On the one hand, it simplifies the structure of the water tank 2. On the other hand, since the water outlet hole is provided on the convex structure 8, if the water outlet hole leaks and the amount of leaked water is small, the leaked water accumulates at the connection between the groove 9 and the convex structure 8, preventing it from spreading.

[0046] In one embodiment, multiple convex structures 8 are arranged in multiple rows, and soft glue is provided on the top of the convex structure 8 close to the middle of the water tank 2. The soft glue and the water outlet hole are located on different convex structures 8. The multiple convex structures 8 enhance the positioning effect to a certain extent. In addition, since the multiple convex structures 8 are arranged in multiple rows, the water tank 2 can be positioned from multiple directions. In the embodiment, the convex structures 8 can be set to 4, and the 4 convex structures 8 are arranged along the edge of the bottom of the water tank 2, with 2 provided on one side of the bottom of the water tank 2 close to the axis of the floor washer and 2 provided on the side away from the axis of the floor washer. The 4 convex structures 8 position the water tank 2 from multiple directions, improving the stability of the water tank 2 during use. Further, soft glue is provided on the top of the convex structure 8 close to the middle of the water tank 2, which can play a certain buffering effect to prevent the convex part from being damaged when the water tank 2 falls.

[0047] In this embodiment, a floor washer is proposed, which has a water tank 2 that is convenient for disassembly and assembly. The specific steps for disassembling and assembling the water tank 2 of the floor washer are as follows: The floor washer has two parts, an upper body 1 and a lower body 3. The adjustment covers 4 on both sides of the upper body 1 are designed as open covers. The size of the open cover is set to be 20 cm in length, 10 cm in width, and 2.2 cm in thickness, and the material is ABS plastic. This design of the open cover can effectively prevent users from being pinched when installing or removing the water tank 2, and at the same time improves the overall appearance integrity of the floor washer; Two buckles are installed at the connection position between the upper body 1 of the floor washer and the water tank 2. The distance between these two buckles is 112 mm, the material is POM, and the shape is long strip. The size of the buckle is: width 6 mm, length 87 mm, and the buckle engagement amount is 4.5 mm. Avoid designing the buckle on the water tank 2, which simplifies the structure of the water tank 2 and reduces the manufacturing cost at the same time; Four protruding structures 8 are provided at the bottom of the water tank 2. The overall height dimension of these four protruding structures 8 is 16.5 mm, and the material is hard plastic. When installing the water tank 2, first insert the four protruding structures 8 at the bottom of the water tank 2 into the corresponding grooves 9 of the lower body 3 in advance, and then directly push the bottom of the water tank 2 inward. When the "click" sound of the buckle is heard, it means the installation is completed; When disassembling the water tank 2, put the back of the hand into the open cover, make the open cover rotate around the rotating shaft 410, and lift the buckle upward during the rotation to unlock the top of the water tank 2. Then, hold the handle of the water tank 2 with the palm and take out the water tank 2 outward and upward, realizing the quick installation and disassembly of the water tank 2. At the same time, it also solves the problem of inconvenient operation of personnel during the water filling process, improving the use efficiency and user experience of the floor washer.
