[0004] The transmission assembly needs to be provided with a rack on the mop, and a gear set with multiple gears is provided in the gear cover plate. Not only is there a large number of parts, but also the matching requirements between the parts are high, which makes the assembly very easy to be damaged. Utility Model Content

[0005] In view of the shortcomings of the transmission components in the existing water supply mechanism, such as large number of parts, high matching requirements and easy damage, the first object of the utility model is to provide a water supply component with reduced number of parts and lower matching requirements.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A water supply assembly includes a transmission assembly and a water outlet assembly. The transmission assembly includes a rotatable friction wheel and a connecting rod. One end of the connecting rod is eccentrically connected to the friction wheel and the other end of the connecting rod is hinged to the water outlet assembly. When the friction wheel rotates, the water outlet assembly is driven to discharge water through the connecting rod.

[0008] By adopting the above scheme, the rotation of the friction wheel directly drives the connecting rod to move eccentrically around the friction wheel, and the movement of the connecting rod directly realizes the water discharge of the water outlet assembly. Compared with the prior art, the connection method of the connecting rod and the water outlet assembly is consistent, and only one friction wheel is required to drive the connecting rod to move, omitting the gear set structure. While simplifying the structure, it also significantly reduces the requirements for fitting accuracy, thereby reducing the probability of damage to each part due to the destruction of fitting accuracy.

[0009] Preferably, the water outlet assembly includes a base with a water inlet, and a piston cylinder and a water outlet cylinder located on the base and connected to each other through the base. A piston rod is sealed and moved inside the piston cylinder, and the upper end of the piston rod is hingedly engaged with a connecting rod. The water inlet is provided with a first one-way valve that conducts one-way flow from the outside to the inside of the base, and a second one-way valve that conducts one-way flow from the base to the water outlet cylinder is provided between the water outlet cylinder and the base.

[0010] By adopting the above scheme, the movement of the connecting rod drives the piston rod to move back and forth in the piston cylinder. When the piston rod rises, the external water enters the rodless cavity of the base and the piston cylinder; when the piston rod descends, the piston rod squeezes the water in the piston cylinder and the base and squeezes the water out of the water outlet cylinder.

[0011] Preferably, the friction wheel is rotatably arranged on the outer wall of the water outlet cylinder and / or on the mounting component for mounting the water supply assembly.

[0012] Preferably, the outer ring wall of the friction wheel is evenly distributed with friction teeth for increasing friction force.

[0013] With the above solution, the friction teeth increase the friction between the friction wheel and the flat mop, and as the flat mop moves, it is easier to drive the friction wheel to rotate.

[0014] Preferably, the connecting rod is rotatably arranged on the friction wheel through a quick-mount structure, and the quick-mount structure includes an eccentric shaft eccentrically protruding on one side of the friction wheel, a limit block protruding on the side of the eccentric shaft away from the friction wheel, and a deformation groove recessed in the center of the limit block, and a center hole for introducing the friction wheel and an introduction inclined surface for allowing the friction wheel to enter the eccentric shaft are symmetrically arranged on both sides of the deformation groove on the limit block.

[0015] By adopting the above scheme, when the friction wheel is squeezed into the inclined surface, the limit block moves inward along the deformation groove to allow the friction wheel to pass through the limit block and slide onto the eccentric shaft. After the limit block is reset, the limit friction wheel is disengaged from the eccentric shaft, and finally the eccentric wheel is installed on the eccentric shaft.

[0016] The second purpose of the utility model is to provide a mop bucket, comprising an outer bucket, an inner bucket and a bucket cover, the outer bucket is divided into a clean water area and a dirty water area, the inner bucket is detachably arranged in the dirty water area, the inner bucket comprises a cleaning area and a wiping area which are interconnected, the clean water area is provided with the water supply assembly, a cleaning port and a wiping port are provided on the bucket cover, when a flat mop matched with the mop bucket enters the cleaning area from the cleaning port, friction force is driven to rotate, and the water supply assembly supplies water to the cleaning area.

[0017] By adopting the above scheme, the water supply component is installed in the mop bucket for cleaning and dirt separation. After the flat mop is inserted into the cleaning port, the reciprocating up and down movement can drive the friction wheel to switch between forward and reverse rotation, thereby driving the water supply component to pump out the water in the clean water bucket and supply it to the flat mop, thereby achieving cleaning of the flat mop.

[0018] Preferably, the barrel cover is provided with a water uniforming assembly that uniformly guides the water provided by the water supply assembly into the cleaning area, and the water uniforming assembly includes a water uniforming groove recessed on the barrel cover and connected to the cleaning port on one side, a water baffle plate clamped at the upper end of the water uniforming groove for blocking water splashing, and a water uniforming member that uniformly sprays the water sprayed by the water outlet assembly into the water uniforming groove.

[0019] By adopting the above scheme, the water distribution component can disperse the water sprayed from the water outlet tube into the water distribution groove and evenly supply it to the flat mop, so that the sprayed water can fully cover the wiped object of the flat mop.

[0020] Preferably, the water uniforming member includes a water outlet groove opened on the side wall of the water uniforming groove, which is connected to the cleaning area and extends to both sides of the cleaning area, a diverter strip protruding from the bottom of the water uniforming groove and parallel to the water outlet groove, and a water guide strip protruding at intervals on one side of the diverter strip close to the water outlet groove, and a water guide channel is formed between the water guide strips.

[0021] By adopting the above scheme, the water in the water outlet tube enters the water uniforming groove and is blocked by the intercepting strip. When the accumulated water level is higher than the intercepting strip, the water exceeding the water level can enter each water guide channel at the same time and flow out of the water outlet groove evenly.

[0022] Preferably, the barrel cover is provided with an indicator component that shows whether the water outlet assembly is discharging water. The indicator component is an indicator impeller. A mounting tube is protruding from the bottom of the water uniforming groove. A water outlet hole connected to the water outlet assembly is provided at the bottom of the mounting tube. The indicator impeller rotates horizontally in the mounting tube, and the water baffle is made of a transparent material.

[0023] By adopting the above scheme, the user can identify the water supply component and the water level status in the clean water area by observing the status of the indicating impeller. When the indicating impeller rotates, it means that the water outlet tube is in normal condition and the water level in the clean water area is reliable; when the indicating impeller stops rotating, it means that the water level in the clean water area is too low or the water supply component fails, and the user needs to check.

[0024] Preferably, the inner barrel is provided with a sewage discharge structure to prevent a large amount of sewage from accumulating in the inner barrel. The sewage discharge structure includes a sewage guide ring groove which is circumferentially recessed at the upper end of the inner barrel. Cleaning components and wiping components are respectively provided on both sides of the sewage guide ring groove corresponding to the cleaning area and the wiping area. A sewage guide port is provided on the sewage guide ring groove to guide all the sewage into the sewage area.

[0025] By adopting the above scheme, the sewage guide ring groove can simultaneously accumulate most of the sewage produced by cleaning and most of the water scraped off by scraping. After these sewage are gathered, they are guided into the sewage bucket from the sewage guide port.

[0026] Preferably, the sewage guide port is located at a low position of the sewage guide ring groove, and the sewage guide ring groove has a slope for guiding sewage to a low position.

[0027] By adopting the above solution, the sewage outlet is located at a low position to ensure that the sewage in the sewage guide ring groove is completely discharged.

[0028] Preferably, a structure for preventing accidental touch of the flat mop from touching the bottom sewage is provided in the inner barrel, and the structure for preventing accidental touch includes a dirt holding groove which is recessed in the middle of the bottom end of the inner barrel.

[0029] By adopting the above scheme, the dirt tank can accumulate a small amount of sewage generated by cleaning and scraping. The maximum descending stroke of the flat mop is located at the upper end of the dirt tank and will not touch the sewage, ensuring that the flat mop will not accidentally touch the sewage during cleaning and scraping.

[0030] Preferably, a main sewage outlet is provided on the outer barrel, a secondary sewage outlet pipe is convexly provided on the inner barrel and is connected to the sewage tank and extends to the main sewage outlet, and a sewage outlet cover is provided on the outer barrel and is threadedly sealed with both the main sewage outlet and the secondary sewage outlet pipe.

[0031] By adopting the above scheme, only one sewage cover is needed to close or open the main sewage outlet and the secondary sewage pipe at the same time, which facilitates sewage discharge and prevents sewage in the sewage area from entering the sewage tank.

[0032] The utility model has significant technical effects due to the adoption of the above technical scheme: a new water supply component is designed and applied in a mop bucket, and after the flat mop is inserted into the cleaning port of the mop bucket, the vertical reciprocating motion of the flat mop can drive the friction wheel to switch between positive and negative reciprocating rotations, and the rotation of the friction wheel drives the connecting rod to switch between positive and negative eccentric movements around the friction wheel, thereby realizing the cyclic reciprocating telescopic motion of the piston rod and realizing the continuous water discharge from the water outlet cylinder. In the water outlet component, the switching of the connecting rod to drive the positive and negative reciprocating motion can be realized by only one friction wheel, omitting the existing gear set structure, significantly reducing the requirements for fitting accuracy, and not prone to damage caused by the destruction of the fitting accuracy of each part.
