The present disclosure belongs to the field of cleaning tools, and more particularly relates to a mop bucket for washing and spinning-drying mops.
The patent document numbered CN116669611A discloses a bucket assembly. The bucket assembly includes an inner bucket assembly and an outer bucket assembly. The inner bucket assembly includes a rinse barrel, a first reservoir, a fluid connection between the rinse barrel and the first reservoir, and at least one closure element disposed at the fluid connection and movable between an open position and a closed position. The inner bucket may include a filling hole and a plug. When the at least one closure element is in the open position, the first reservoir optionally seals in other positions.
The main feature of the solution is that the first reservoir is arranged to store clean water, and the closure element is opened before each cleaning of the mop so that the first reservoir injects a certain amount of clean water into the rinse barrel. In this way, the mop can be cleaned with clean water every time when it is needed to clean the mop, which is more conducive to cleaning the mop cleaner than the case where the same bucket of water is repeatedly used for cleaning the mop.
However, this solution still has the following disadvantages: firstly, the closure element is arranged on the first reservoir and needs to be opened before cleaning the mop each time; after the rinse barrel is filled with water, the closure element needs to be closed, that is, the user needs to bend or squat down to operate the closure element twice, which is not convenient for use. Secondly, when the mop is used to clean different positions, since there are usually differences in dirt levels at different positions, the dryness and wetness of the mop after mopping vary, and the amount of water injected into the rinse barrel each time is basically the same, which is not conducive to flexibly adjusting the amount of water required for cleaning the mop according to the dirt level and dryness and wetness of the mop.
The technical problem to be solved by the present disclosure is as follows: in view of the shortcomings existing in the prior art, a mop bucket with clean and dirty water separation is provided, with which a mop can be cleaned with clean water every time when using the mop. It is convenient to fill water into the tub, users don't have to bend over, and the amount of water filled can be controlled by users according to needs.
In order to achieve the purpose of the present disclosure, the following technical solution is adopted: a mop bucket with clean and dirty water separation comprising a mop and a mop bucket for cleaning the mop;
As a preferred embodiment: a bottom of a side wall of the tub is provided with a drainage pipe extending towards the partition, and an outer wall of the tub is provided with a mounting bracket, and a valve plate is rotatably connected to the mounting bracket; a plug capable of closing an outer end of the drainage pipe is arranged on the valve plate, and a valve plate spring is connected between the valve plate and the mounting bracket to keep the plug and the outer end of the drainage pipe in a closed state;
Compared with the prior art, the beneficial effects of the disclosure are as follows: since a reciprocating pump driven by a tub is arranged in the clean water area, when cleaning the mop, the reciprocating pump can be driven to operate and fill water into the tub by pressing down the mop. At this moment, the mop acts as a control lever of the reciprocating pump, so that there is no need to bend or squat during the process of filling water into the tub.
More importantly, after the mop is cleaned every time, dirty water with solid dirt may remain at the bottom of the tub. However, since the tub is located within the clean water area and can move up and down, it becomes a problem to discharge the dirty water in the tub into the dirty water area.
To this end, the present disclosure specifically designs a valve assembly to solve the above problems. Specifically, a diversion trench driven by a lever is arranged so that the dirty water flowing out of the drainage pipe can be discharged into the dirty water area on the other side of the partition through the diversion trench, and when no external force acts on the diversion trench, it is completely within the range of the clean water area and will not affect the up-and-down movement of the tub. In addition, since the pushing part on the diversion trench contacts with the valve plate and then pushes the valve plate to open only when the water outlet end of the diversion trench moves beyond the partition, it is difficult for the dirty water from the tub to flow into the clean water area. That is, the valve assembly can realize the movement of the diversion trench and the opening of the valve plate in turn by pulling the lever, so as to guide the dirty water in the tub into the dirty water area, so that no dirty water will be left in the tub when the mop is cleaned next time.

Referring to
A tub 3 capable of moving up and down is arranged above the clean water area in the outer bucket, a reciprocating pump 6 capable of pumping water from the clean water area to the tub is further arranged in the clean water area, the tub is connected with the reciprocating pump, and the tub can move downward under push of a mop 9 and drive the reciprocating pump to operate; a bottom of the tub is provided with a valve assembly capable of discharging water in the tub to the dirty water area, and the valve assembly has a movable water outlet end 310; when the valve assembly is in a closed state, the water outlet end is away from the partition; only when the tub is located at an upper limit position and the water outlet end moves above the dirty water area, the valve assembly switches from the closed state to an open state; and a spin-drying basket 4 for drying a mop is rotatably arranged above the dirty water area in the outer bucket.
In the above solution, when the mop is cleaned, the reciprocating pump can be driven to operate by pressing down the mop so as to fill water into the tub. At this moment, the mop acts as a control lever of the reciprocating pump, so that there is no need to bend or squat during the process of filling water into the tub.
In addition, the amount of water filled into the tub can be flexibly adjusted by controlling the number of times the reciprocating pump is pressed and the pressing amplitude. When a mop is slightly dirty, less water can be used to wash the mop so as to achieve the purpose of saving clean water; when the mop is seriously dirty, more water need to be used to wash the mop so as to achieve the purpose of thorough cleaning of the mop.
A cover body 2 is detachably connected to an upper end of the outer bucket, a washing port 2a is provided on the cover body at a position corresponding to the tub, and a spin-drying port 2b is provided at a position corresponding to the spin-drying basket. A dirty water baffle 25 is provided at a position between the spin-drying basket and the partition at a lower end of the cover body to prevent dirty water thrown out by the spin-drying basket from splashing into the clean water area. A guide wall 23 which is in sliding connection with the tub is arranged at a lower end of the cover body located at a periphery of the washing port, and a limiting part 231 which prevents the tub from separating from the guide wall is arranged at a lower portion of the guide wall. As shown in
A part of the cover body that is located within the clean water area is provided with a water filling port 21; an indicator 24 for indicating whether the clean water area is filled with water is connected in a sliding manner along a vertical direction in the part of the cover body that is located within the clean water area; a float 7 is arranged in the clean water area; when a water level in the clean water area reaches a set height, the float drives the indicator to move upward by buoyancy.
The reciprocating pump 6 is a piston pump, and the piston pump is fixedly installed in the clean water area and located below the tub; Referring to
The diameter of the piston body is about 100 mm, and the effective height of the piston barrel is 40-70 mm. Therefore, each time when the piston rack is pressed to a limit position, the piston pump can roughly pump 300-550 ml of clean water into the tub, that is, only 1-3 times of pressing the piston pump are required for each cleaning of the mop. As shown in
As shown in
an upper end of the water inlet baffle is provided with a water inlet valve plate 64, and the water inlet valve plate and the water inlet constitute a water inlet check valve that conducts unidirectionally from bottom to top; the water inlet valve plate is clamped between the upper end of the water inlet baffle and the return spring; a water outlet is arranged in the water outlet pipe joint, and a valve ball 68 is installed at an upper end of the water outlet in the water outlet pipe joint; the water outlet and the valve ball form a water outlet check valve that conducts unidirectionally from bottom to top; a limiting part 690 for limiting the moving range of the valve ball is arranged at an inner lower part of the water outlet pipe.
When clean water is injected into the clean water area, the water pressure will force the water inlet valve plate to open, namely, the water inlet check valve will be connected, and the air at the bottom of the piston barrel will be discharged through the water outlet check valve, the water outlet pipe and the water outlet joint in turn. If the piston body and the piston barrel are not perfectly sealed, clean water will completely fill the inside of the barrel underneath the piston body. If the piston body and the piston barrel are perfectly sealed, clean water can only enter at a point where the bottom of the piston barrel is approximately level with an inner top of the water outlet casing.
When the piston rack is pressed downwards, the water inlet check valve remains closed, and clean water in the pump cavity forces the water outlet check valve to be conducted. Clean water passes through the water outlet pipe and the water outlet joint in turn and is injected into the tub. After the external force pressing the piston rack is removed, the piston rack together with the piston body moves upwards under the action of a return spring. In this process, the water outlet check valve remains closed, the water inlet check valve opens, and the water in the clean water area flows into the pump cavity.
An outer wall of an upper part of the housing is provided with more than 2 connecting outer bulges 615 at equal angles, and an inner wall of the limiting sleeve is provided with L-shaped grooves 671 relatively fixedly connected to each connecting outer bulge; an inner top of the limiting sleeve is provided with a plurality of elastic pressing parts 672 at equal angles, and the elastic pressing parts are pressed against the upper end of the piston barrel. In actual production, the piston barrel is generally cut from extrusion-molded long plastic pipes. In order to reduce the requirements for its length accuracy, an elastic tight part is set so that the length of the piston barrel is within a certain error range, and the limiting sleeve can fix the piston barrel in the housing. As shown in
As shown in
The upper end of the water inlet baffle is provided with a positioning post 616, and the water inlet valve plate and the return spring are sleeved on the positioning post; a lower end of the piston rack is provided with a spring cavity for accommodating an upper part of the return spring. That is, when the piston rack moves downward to a limit position, an upper part of the positioning post is inserted into the spring cavity. That is, the positioning post and the spring cavity are not only used to locate the return spring, but also will not affect the movable distance of the piston body.
Specifically, referring to
A diversion trench 31 for guiding water flowing out from the drainage pipe to the dirty water area is slidably installed on the mounting bracket or the drainage pipe, and an end of the diversion trench near the partition is the water outlet end 310. Alever 32 is further movably installed on the mounting bracket, and a lower end of the lever is in transmission connection with the diversion trench, so that the water outlet end of the diversion trench can move from above the clean water area to above the dirty water area; a diversion trench return spring 35 is installed between the mounting bracket and the lever or the diversion trench, so that the water outlet end of the diversion trench can return from above the dirty water area to above the clean water area. A drainage gap 111 is arranged on the partition at a position corresponding to the water outlet end, and the water outlet end of the diversion trench extends above the dirty water area through the drainage gap.
The diversion trench is provided with a pushing part capable of driving the valve plate to rotate, so that the plug and the outer end of the drainage pipe are switched from a closed state to an open state; only when the diversion trench moves under drive of the lever until the water outlet end exceeds the partition, the pushing part 312 contacts with the valve plate and pushes the valve plate to rotate; and the valve assembly is composed of the mounting bracket, the valve plate, the diversion trench and the lever.
The cover body is provided with a lever through hole 22 at the position corresponding to the lever for the upper end of the lever to pass out from bottom to top, that is, when the tub is in an initial position, the upper part of the lever is located above the cover body.
Further, in the above solution, a diversion trench 31 driven by a lever 32 is arranged so that the dirty water flowing out of the drainage pipe can be discharged into the dirty water area 1b on the other side of the partition through the diversion trench, and when no external force acts on the diversion trench, it is completely within the range of the clean water area 1a and will not affect the up-and-down movement of the tub. In addition, since the pushing part on the diversion trench contacts with the valve plate and then pushes the valve plate to open only when the water outlet end of the diversion trench moves beyond the partition, it is difficult for the dirty water from the tub to flow into the clean water area. That is, the valve assembly can realize the movement of the diversion trench and the opening of the valve plate in turn by pulling the lever, so as to guide the dirty water in the tub into the dirty water area, so that no dirty water will be left in the tub when the mop is cleaned next time.
For the valve assembly, more specifically, as shown in
The outer wall of the tub 3 is provided with a valve slot 304 for fixing the mounting bracket 36, the inner bottom of the tub is a confluence slope 302, and the drainage pipe is located at the lowest point of the confluence slope so that the dirty water in the tub can be completely discharged through the drainage pipe. A supporting bulge 303 extending upward is arranged at a middle position of the inner bottom of the tub.
The mop 9 comprises a mop head with a wiping cloth head and a mop rod connected to an upper end of the mop head;
A pedal driving mechanism 5 for driving the spin-drying basket to rotate is arranged below the spin-drying basket outside the outer bucket. As shown in
When in use, water is injected into the clean water area 1a of the outer bucket 1 through a water filling port until an upward movement of the indicator is seen, which indicates that the water level in the clean water area reaches a set value and the water filling is completed.
Then put the mop head of the mop into the tub, press down the mop rod to drive the tub together with the piston rack and piston body to move downwards. Press down the mop rod 1-3 times according to the dryness and dirt degree of the mop head, so that the piston pump can inject an appropriate amount of clean water for cleaning the mop into the tub. After cleaning the mop head, move the mop head to the spin-drying basket for spin-drying.
If dirty water remains in the tub, it is only necessary to move the lever 32 to drive the diversion trench to move to the water outlet end 310 above the dirty water area and open the valve plate 33 so that the dirty water remaining in the tub can be discharged into the dirty water area. If there is no residual dirty water in the tub, or the user thinks that the residual dirty water is very little and has no significant effect on re-cleaning the mop head, it may not be necessary to operate the lever.
