DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0041] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0042] This embodiment mainly describes the double-layer mop bucket of the flat mop that ensures cleanliness by setting the grooves and discharging water during scraping, as follows:

[0043] Embodiment 1

[0044] like Figure 1-13 As shown, the double-layer mop bucket of the flat mop includes an outer bucket 1, a detachable inner bucket 2 arranged in the outer bucket 1, a positioning plug 4 that simultaneously connects the outer bucket 1 and the inner bucket 2, a cover assembly 001 that is detachably covered on the outer bucket 1, and a water supply assembly 002 that is installed on the cover assembly 001 and inserted into the outer bucket 1. A handle 3 is usually rotatably installed on the outer bucket 1, and the handle 3 facilitates the extraction and transportation of the mop bucket.

[0045] In this embodiment, a partition 1a is provided in the outer barrel 1, and the partition 1a divides the outer barrel 1 into a clean water area 1b and a sewage area 1c. The inner barrel 2 is placed in the sewage area 1c. The positioning plug 4 is inserted into the outer barrel 1 and the inner barrel 2 at the same time to limit the separation of the inner barrel 2 and the outer barrel 1, and the water supply component 002 is inserted into the clean water area 1b. A cleaning port 001a and a wiper port 001b are provided on the cover body component 001. The cleaning port 001a and the wiper port 001b are located above the inner barrel 2. The area in the inner barrel 2 corresponding to the cleaning port 001a is the cleaning area 2a, and the area in the inner barrel 2 corresponding to the wiper port 001b is the wiper area 2b.

[0046] In other embodiments, the outer barrel 1 can also be independently configured into two barrel bodies, one of which is a clean water area 1b, and the other is a sewage area 1c, and one barrel body is provided with a base, and the other barrel body is placed on the base, and the cover assembly 001 is covered on the two barrel bodies.

[0047] The flat mop includes a mop head and a mop rod rotatably mounted on the upper end surface of the mop head (the flat mop is not shown in the drawings of the specification). When the flat mop is cleaned and dehydrated through the mop bucket, the mop head of the flat mop is arranged vertically, that is, the mop rod is basically parallel to the mop rod. The mop head is first inserted into the cleaning area 2a from the cleaning port 001a. During the insertion process, the mop head is supplied with water by acting on the water supply component 002. After cleaning, the mop head is separated from the cleaning area 2a and the cleaning port 001a, and then inserted into the wiping area 2b from the wiping port 001b. The mop head can wipe water, and the sewage scraped off the mop head can flow into the sewage area 1c.

[0048] like Figure 2-5 , Figure 9-11As shown, a recessed groove 2c is provided at the bottom of the inner bucket 2, and the width of the groove 2c is smaller than the width of the mop head, which can effectively limit the mop head from being inserted to the bottom. That is, when the mop head is cleaned by water supply assembly 002, the mop head will drip onto the bottom sewage of the inner bucket 2 due to the downward flow of water during cleaning. The setting of the groove 2c can effectively prevent the mop head from being contaminated again, and when the mop head is scraped and cleaned, it can also effectively prevent the mop head from being contaminated by the sewage in the inner bucket 2, thereby ensuring the cleanliness of the mop head when scraping and cleaning.

[0049] In other embodiments, a plurality of protruding ribs may be provided at the bottom of the inner barrel 2, and the ribs may limit the mop head of the flat mop from being inserted to the bottom.

[0050] A drain port 1d is provided on one side of the sewage area 1c of the outer barrel 1, and a drain port 3 2d is provided on this side of the inner barrel 2. When the inner barrel 2 is placed in the sewage area 1c of the outer barrel 1, the drain port 1d is aligned with the drain port 3 2d, and the positioning plug 4 is inserted into the drain port 1d and the drain port 3 2d in sequence from the outside of the outer barrel 1. To avoid water leakage, a waterproof ring is provided on the positioning plug 4 (the waterproof ring is not shown in the drawings of the specification). The waterproof ring has two layers along the insertion direction of the positioning plug 4, one layer of waterproof ring cooperates with the drain port 1d, and the other layer of waterproof ring cooperates with the drain port 3 2d. The waterproof ring limits water leakage at the drain port 1d and the drain port 3 2d. Preferably, the number of waterproof rings may also be one.

[0051] A drain port 1f is provided on the side wall of the clean water area 1b of the outer barrel 1, and the drain port 1f is convenient for cleaning and replacing the remaining clean water in the clean water area 1b, and a water plug 5 is detachably installed at the drain port 1f, and the water plug 5 can limit water leakage at the drain port 1f.

[0052] In order to ensure that the inner barrel 2 is placed in the sewage area 1c of the outer barrel 1 to achieve a positioning effect, a pipe wall 1e extending into the sewage area 1c is provided at the drain outlet 1d on the outer barrel 1, and a convex wall 2e extending outward is provided at the drain outlet 1d on the inner barrel 2. The convex wall 2e can be framed on the pipe wall 1e. Preferably, the pipe wall 1e can be a pipe body structure, and the convex wall 2e can be an arc structure, that is, a local pipe body structure.

[0053] Due to the setting of the groove 2c in the inner barrel 2 and the thickness of the barrel wall of the inner barrel 2 is usually kept consistent, a pit 2f is formed at the bottom outside the inner barrel 2. In this embodiment, the pit 2f is arranged in the middle position of the inner barrel 2, that is, the pit 2f is located on both sides of the outer wall of the groove 2c, and the bottom of the sewage area 1c of the outer barrel 1 is protruding with a step 1g that can be inserted into the pit 2f. When the inner barrel 2 is placed in the sewage area 1c of the outer barrel 1, the step 1g is inserted into the pit 2f, and the convex wall 2e is framed on the tube wall 1e. The cooperation of the two places makes it possible for the inner barrel 2 placed in the outer barrel 1 to be accurately positioned and stably placed.

[0054] A circle of outer flange 2g is provided at the upper edge of the inner barrel 2, and the outer flange 2g close to the partition 1a can be mounted on the partition 1a.

[0055] like Figure 4-8 , Fig.13 As shown, the cover body assembly 001 includes an upper cover 6, a bottom plate 7, a water retaining cover 8 and a wiper 9. The upper cover 6 and the outer barrel 1 are detachably installed through a snap-fit ​​structure. The bottom plate 7 is fixed under the upper cover 6. The cleaning port 001a and the wiper port 001b are arranged on the upper cover 6 and the bottom plate 7. In this embodiment, the cleaning port 001a and the wiper port 001b are independently arranged, and two avoidance ports 001e are arranged on the cover body assembly 001, one of which is connected to the cleaning port 001a, and the other is connected to the wiper port 001b. The water retaining cover 8 is installed above the upper cover 6 and is located on one side of the cleaning port 001a, and slide grooves 7a are opened on both sides of the bottom plate 7. The wiper 9 is slidably connected to the slide groove 7a, and the wiper 9 partially extends into the wiper port 001b.

[0056] Preferably, a water injection port 6c is provided through the upper cover 6 to facilitate water injection into the clean water area 1b of the outer barrel 1.

[0057] To ensure that the water supply component 002 acts when the mop head is inserted into the cleaning port 001a, the water supply component 002 can use the water in the clean water area 1b to wet the mop head. The cleaning port 001a is located between the wiper port 001b and the clean water area 1b, that is, the cleaning area 2a is located between the wiper area 2b and the clean water area 1b; at the same time, to prevent the water in the cleaning area 2a from splashing into the clean water area 1b, a lower edge 7d extending downward is provided on the inner wall of the cleaning port 001a of the bottom plate 7 near the cleaning area 2a, and the lower end of the lower edge 7d is lower than the partition 1a in the outer barrel 1.

[0058] A connecting pipe 6a connected to the water supply component 002 is provided below the upper cover 6, and the water supply component 002 is supplied with water through the connecting pipe 6a, and a water guide plate 6b located in the cleaning port 001a is provided on the upper cover 6, and a water retaining cover 8 is installed on the water guide plate 6b, and a chamber 001c is formed between the water retaining cover 8 and the water guide plate 6b. The connecting pipe 6a is connected to the chamber 001c, and a tooth plate portion 7b located in the cleaning port 001a is provided on the bottom plate 7. The tooth plate portion 7b can scrape the materials adhered to the mop head, and a plurality of through holes 8a are provided on the water retaining cover 8. The water in the chamber 001c can flow into the cleaning port 001a from the plurality of through holes 8a along the water guide plate 6b.

[0059] A water guide groove 001d is formed between the bottom plate 7 and the upper cover 6. When the mop head is inserted from the wiper port 001b, the mop head presses down on the wiper plate 9, and the bottom plate 7 supports the wiper plate 9, that is, the wiper plate 9 wipes and cleans the mop head. The sewage and stains scraped off the mop head by the wiper plate 9 flow into the water guide groove 001d along the wiper plate 9. A drain port 7c is provided on the bottom plate 7, and the drain port 7c connects the water guide groove 001d with the sewage area 1c.

[0060] When the mop head is lifted up, due to the sliding connection between the wiper plate 9 and the bottom plate 7, the mop head can drive the wiper plate 9 to slide. Preferably, the slide groove 7a is arranged obliquely, and the upper end of the slide groove 7a is farther away from the wiper port 001b than the lower end, so that when the wiper plate 9 slides upward along the slide groove 7a, the wiper plate 9 is away from the wiper port 001b, and the wiping effect of the wiper plate 9 on the mop head is weakened or even eliminated.

[0061] In order to prevent the sewage and stains scraped off by the wiper 9 from flowing into the inner barrel 2, an escape portion 2h is provided on the inner barrel 2, and the escape portion 2h can ensure that the sewage and sewage flowing out from the drain port 7c flow into the sewage area 1c of the outer barrel 1.

[0062] In order to facilitate the flat mop to be directly inserted into the wiper port 001b for wiper cleaning after being taken out from the cleaning port 001a, the avoidance port 001e is arranged on the same side of the cleaning port 001a and the wiper port 001b.

[0063] like Figure 6-8 , Fig.12 As shown, the water supply component 002 includes a double-barreled pipe fitting 10, a one-way valve 11, a one-way valve 12, a piston 13, a pull rod 14 and a gear set 01. The double-barreled pipe fitting 10 is provided with a tube body 10a and a tube body 10b arranged in parallel, and a bottom pipe 10c arranged at the lower ends of the tube body 10a and the tube body 10b. The tube body 10a and the tube body 10b are both connected to the bottom pipe 10c. The double-barreled pipe fitting 10 is inserted into the clean water area 1b of the outer barrel 1. The tube body 10a of the double-barreled pipe fitting 10 is connected to the connecting pipe 6a. The one-way valve 11 is installed at the bottom of the bottom pipe 10c, the one-way valve 12 is installed in the tube body 10a, and the piston 13 is slidably installed in the tube body 10b. One end of the pull rod 14 is rotatably connected to the piston 13, and the other end is rotatably connected to the gear set 01, and the gear set 01 is fixedly installed on the bottom plate 7.

[0064] Preferably, one-way flow occurs from the clean water area 1b to the bottom pipe 10c through a one-way valve 11, and one-way flow occurs from the bottom pipe 10c to the pipe body 10a through a one-way valve 2 12.

[0065] A mounting port 2i is provided on the bottom plate 7, and the mounting port 2i is connected to the cleaning port 001a. To prevent the double-barrel pipe fitting 10 from detaching from the upper cover 6, a fixing portion 10d is provided on the double-barrel pipe fitting 10, and the fixing portion 10d can be fixedly connected to the outer wall of one side wall of the mounting port 2i by screws.

[0066] like Figure 4-7 As shown, the gear set 01 includes a driving tooth 15 installed in the installation port 2i and partially exposed in the cleaning port 001a, a fixed plate 19 fixed on the outer wall of the other side wall of the installation port 2i, a driven tooth 16 rotatably installed between the fixed plate 19 and the bottom plate 7 and can be driven by the driving tooth 15, an intermediate tooth 17 rotatably installed between the fixed plate 19 and the bottom plate 7 and meshing with the driven tooth 16, and an eccentric tooth 18 rotatably installed on the fixed plate 19 and meshing with the intermediate tooth 17. The axial end of the eccentric tooth 18 deviating from its rotation installation axis is provided with an eccentric shaft 18a, and the other end of the pull rod 14 is rotatably connected to the eccentric shaft 18a.

[0067] The driven teeth 16 and the driving teeth 15 can realize rotation transmission through the spline shaft or the non-circular shaft and the hole, and the rotation axes of the driving teeth 15, the driven teeth 16, the intermediate teeth 17 and the eccentric teeth 18 are perpendicular to the opening direction of the cleaning port 001a.

[0068] In this embodiment, by inserting the mop head of the flat mop into the cleaning port 001a, the lower end surface of the mop head can act on the active gear 15 to rotate, and the active gear 15 drives the driven gear 16 to rotate. The driven gear 16, the intermediate gear 17 and the eccentric gear 18 are engaged to realize rotation transmission, and the eccentric shaft 18a on the eccentric gear 18 will drive the piston 13 to move up and down in the tube body 10b of the double-tube pipe fitting 10 through the pull rod 14 during the rotation process.

[0069] When the piston 13 moves upward in the tube body 10b, the one-way valve 11 is turned on, the one-way valve 12 is blocked, and the water in the clean water area 1b enters the bottom pipe 10c; when the piston 13 moves downward in the tube body 10b, the one-way valve 11 is blocked, the one-way valve 12 conducts the water in the bottom pipe 10c along the tube body 10a and the connecting pipe 6a to enter the chamber 001c, and the water in the chamber 001c flows from the plurality of through holes 8a to the water guide plate 6b and flows into the cleaning port 001a to wet the mop head.

[0070] Preferably, the number of the middle teeth 17 is an odd number, so that the downward pressing of the mop head in the cleaning port 001a is synchronized with the downward movement of the piston 13 driven by the pull rod 14, and the upward lifting of the mop head in the cleaning port 001a is synchronized with the upward movement of the piston 13 driven by the pull rod 14.

[0071] In other embodiments, the intermediate teeth 17 may be eliminated so that the eccentric teeth 18 and the driven teeth 16 are directly meshed.
