mop bucket

Abstract

This invention discloses a mop bucket, which includes a mop bucket body with an opening on its upper surface for the mop to extend vertically into the body when folded. The mop bucket also includes a water pump, a water delivery channel, a water storage chamber, and a pressure accumulator. The water pump pressurizes water via a foot pedal. The water delivery channel connects the water pump and the water storage chamber, respectively, and delivers the pressurized water to the water storage chamber, from which it is ejected from a nozzle on the side wall of the chamber. The pressure accumulator is located at the water delivery channel and includes a housing, a first elastic element, and a first piston. The elastic coefficient of the first elastic element is set such that when the water pump pressurizes and delivers water, the first piston moves away from its initial position under the pressure of the water, causing deformation of the first elastic element. When the water pump stops pressurizing, the first elastic element releases pressure, causing the first piston to gradually return to its initial position. This mop bucket improves the cleaning effect of the mop.

Description

Technical Field

[0001] This invention relates to the field of cleaning tools, and more specifically to a mop bucket. Background Technology

[0002] Most mop buckets on the market only have the function of holding water. You fill the mop bucket with an appropriate amount of water, put the mop in the bucket, and clean the mop by shaking or soaking it. However, this method is not very effective at cleaning the mop. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing mop buckets in terms of poor cleaning effect on mops, and to provide a mop bucket.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A mop bucket includes a mop bucket body with an opening on the upper surface of the mop bucket body for a mop to be inserted vertically into the mop bucket body in a folded state.

[0006] The mop bucket also includes:

[0007] A water pump that pressurizes water by foot pedal operation;

[0008] A water storage chamber is located inside the mop bucket. The cross-sectional area of ​​the water storage chamber is larger than that of the water delivery channel. A water outlet is provided on the side wall of the water storage chamber, and the water outlet is located below the opening.

[0009] A water conveying channel, the two ends of which are respectively connected to the water pump and the water storage chamber, the water conveying channel being used to deliver the water pressurized by the water pump to the water storage chamber and spray it out from the water outlet;

[0010] A pressure accumulator includes a housing, a first elastic element, and a first piston. The first piston and the first elastic element are disposed within the housing. A first end of the housing is connected to a water pump via a water delivery channel.

[0011] The second end of the shell is connected to the water storage chamber through the water supply channel;

[0012] The elastic coefficient of the first elastic element is set as follows: when the water pump pressurizes and delivers water, the first piston moves away from its initial position under the pressure of the water and causes displacement, which deforms the first elastic element. When the water pump stops pressurizing, the first elastic element drives the first piston to move, releases the pressure, and causes the first piston to gradually return to its initial position.

[0013] In this technical solution, a water pump is installed inside the mop bucket. The water pump can pressurize and send clean water into the mop bucket body. When the mop is inserted into the mop bucket body, the clean water flows through the water outlet onto the surface of the mop to be cleaned, thereby achieving the purpose of continuously cleaning the mop with flowing clean water and improving the cleaning effect of the mop.

[0014] Meanwhile, since the pressure storage device is connected to the water supply channel, the water pressure in the water supply channel is relatively high when the water pump is working. Under the pressure of the water, the first piston leaves its initial position and is displaced, causing the first elastic element to deform. The first piston is squeezed outward, and the first elastic element stores pressure, increasing the space in the housing that can hold water and increasing the amount of water stored in the housing. When the water pump stops working, the water pressure in the water supply channel and the housing decreases, and the first elastic element rebounds inward to release the pressure. The first elastic element drives the first piston to move towards its initial position and gradually return to its initial position. The space in the housing that can hold water decreases, and the pressure in the housing increases. The water in the water storage chamber continues to spray outward from the water outlet, so that the water in the water storage chamber can still be sprayed out through the water outlet when the water pump stops working. This prolongs the spraying time of the water outlet and increases the spray volume of the water outlet, allowing the mop to be rinsed with more water for a longer time, further improving the cleaning effect of the mop.

[0015] Preferably, the water nozzle is positioned at a height within the mop bucket body such that when the mop is fully inserted into the mop bucket body, the water sprayed from the water nozzle can reach the upper end of the cleaning surface of the mop.

[0016] In this technical solution, by setting the height of the water nozzle to allow water to spray onto the upper part of the mop's cleaning surface, the water on the mop flows downwards from the upper part, thereby making the mop's cleaning surface more thoroughly cleaned.

[0017] Preferably, the mop bucket body includes a bucket body and a bucket lid, the bucket body and the bucket lid are detachably connected, the opening is formed on the bucket lid, the lower surface of the bucket lid has a protrusion facing the bucket body, the bucket body has a first groove corresponding to the protrusion, and the protrusion can be inserted into the first groove.

[0018] In this technical solution, the mop bucket body is made detachable with a detachable body and lid, making it more convenient to use. At the same time, the detachable connection between the bucket body and lid is achieved by using a boss and a first groove, resulting in a simple and reliable structure.

[0019] Preferably, the water pump includes a pump body, a second piston, a foot pedal, and a second elastic element. The foot pedal's fulcrum is located on the outside of the mop bucket body, and the pump body is located inside the mop bucket body. The pump body has a chamber inside, and the second piston and the second elastic element are located in the chamber. The foot pedal is connected to the second piston, and along the extension and retraction direction of the second elastic element, both ends of the second elastic element abut against the upper wall of the chamber and the second piston, respectively.

[0020] The second piston has a connecting portion, which is connected to the foot pedal. The connecting portion has a hollow structure.

[0021] In this technical solution, when using the mop bucket, the foot pedal is pressed down on the outside of the fulcrum. The outside of the foot pedal moves downward under force, while the inside moves upward, driving the second piston to pump water in. Releasing the foot pedal causes the second piston to drive the inside of the foot pedal downward under the action of the elastic element, while the outside of the foot pedal moves upward, pressurizing the pumped water and delivering it to the water delivery channel. Finally, the water is sprayed out from the nozzle to clean the mop. Furthermore, by incorporating a hollow structure at the connection point, the weight of the connection is reduced, making it easier to press the foot pedal.

[0022] Preferably, the outer wall of the mop bucket body is recessed inward to form a receiving cavity, the water pump is disposed below the receiving cavity, the water delivery channel is partially disposed in the receiving cavity, and the outer wall of the mop bucket body located above the water pump has a through hole for the water delivery channel to connect to the water pump.

[0023] By recessing the outer wall of the mop bucket inward to form a receiving cavity, and placing the water delivery channel in the receiving cavity, damage to the water delivery channel can be effectively prevented. At the same time, by providing a through hole on the outer wall of the mop bucket body located above the water pump, the water delivery channel can be connected to the water pump through the through hole.

[0024] Preferably, the lower part of the opening has a lower eave extending vertically downward from the edge of the opening, and the lower eave is provided with a horizontally protruding rib, and there are at least two of the ribs on the lower eave.

[0025] In this technical solution, by setting the lower hanging edge and the protruding rib, it can be ensured that the mop is vertical and not crooked when it is inserted into the mop bucket body from the opening.

[0026] Preferably, the water pump further includes a foot pedal support frame, which includes a base plate and two side plates. Each of the two side plates has a mounting hole. Connecting posts are provided on both sides of the foot pedal at positions corresponding to the two mounting holes. The connecting posts are inserted into the corresponding mounting holes. The foot pedal support frame is separate from the mop bucket body.

[0027] The side wall of the mop bucket body has a clearance hole for the foot pedal to extend into the mop bucket body and connect with the connecting part. In the vertical direction, the size of the clearance hole is larger than the thickness of the foot pedal, and there is a gap between the inner wall of the clearance hole and the foot pedal. In the horizontal direction, the size of the clearance hole is smaller than the size of the foot pedal support frame.

[0028] In this technical solution, a foot pedal is installed on the outside of the mop bucket body, allowing users to easily pump water into the mop bucket body by foot. A gap is provided between the foot pedal and the clearance hole, making the foot pedal move more smoothly when stepped on. Furthermore, the foot pedal support frame is made larger than the clearance hole, facilitating the connection between the foot pedal support frame and the mop bucket body.

[0029] Preferably, there are multiple water outlets, and the multiple water outlets are evenly distributed along the width direction of the opening.

[0030] In this technical solution, by setting multiple water nozzles distributed along the width direction of the mop's cleaning surface on the side wall of the water storage chamber, the coverage area of ​​the water nozzles on the mop's cleaning surface can be increased, so that all parts of the mop's cleaning surface can be effectively cleaned.

[0031] Preferably, the water outlet extends in a horizontal direction.

[0032] By extending the water nozzle horizontally, the water sprays out horizontally and flows downwards, resulting in better cleaning of the mop.

[0033] Preferably, the mop bucket also includes a scraper, the scraper being positioned such that when the mop is inserted into the interior of the mop bucket body, the scraper is in contact with the surface of the mop to be cleaned.

[0034] In this technical solution, by setting a scraper that fits against the surface of the mop to be cleaned, the user can squeeze out the water from the mop and scrape off the dirt when pulling the mop out of the mop bucket.

[0035] Preferably, the scraper is positioned above the water outlet nozzle.

[0036] In this technical solution, by placing the scraper above the water nozzle, it is ensured that the surface of the mop to be cleaned can be squeezed dry after being wetted by water.

[0037] Preferably, the housing also has a tapering section, the cross-sectional area of ​​which gradually decreases along the direction of water flow, and the tapering section is close to the first end of the housing and located upstream of the first piston.

[0038] By setting a tapered section upstream of the first piston inside the housing, the pressure of the tapered section is increased, thereby increasing the water pressure on the first piston and making the pressure storage effect of the pressure storage device better.

[0039] Preferably, the bottom wall of the housing also has a second groove, and the bottom wall of the housing protrudes outward to form the second groove.

[0040] Preferably, the side of the opening away from the water nozzle has an arcuate portion, the shape of which matches the shape of the mop handle.

[0041] In this technical solution, by setting an arc-shaped part that matches the shape of the mop on the side of the opening away from the water nozzle, the opening can guide the user to insert the mop into the mop bucket in the correct direction.

[0042] Preferably, the mop bucket also includes a water inlet, which connects the water pump to an external pipeline, and a filter is provided at the water inlet.

[0043] In this technical solution, the cleanliness of the water delivered to the mop bucket is improved by installing filter cotton at the water inlet.

[0044] Preferably, a one-way valve is provided in the water conveying channel, the one-way valve is located near the outlet of the water pump, and the one-way valve limits the flow direction of water in the water conveying channel to flow from the outlet of the water pump to the water storage chamber.

[0045] In this technical solution, a one-way valve is installed in the water delivery channel to prevent water in the water delivery channel and the water storage chamber from flowing back towards the inlet.

[0046] Preferably, the cross-sectional area of ​​the inlet channel is larger than the cross-sectional area of ​​the outlet channel.

[0047] In this technical solution, by setting the cross-sectional area of ​​the water inlet channel to be larger than that of the water outlet channel, the water pressure when the water is sprayed out at the water outlet can be increased, thereby improving the cleaning effect on the mop.

[0048] Preferably, the ratio of the cross-sectional area of ​​the outlet channel to the cross-sectional area of ​​the inlet channel is defined as a, where 1 / 6 ≤ a ≤ 5 / 6.

[0049] The positive and progressive effects of this invention are as follows: by installing a water pump inside the mop bucket, the water pump can pressurize and send clean water into the mop bucket body. When the mop is inserted into the mop bucket body, the clean water flows through the water outlet onto the surface of the mop to be cleaned, achieving the purpose of continuously cleaning the mop with flowing clean water, thus improving the cleaning effect of the mop. At the same time, since the pressure storage device is connected to the water storage chamber through the water supply channel, the pressure storage device allows the water outlet to continue spraying water even after the foot pedal is stopped, further improving the cleaning effect of the mop.

[0097] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0098] like Figures 1-9 As shown, this embodiment provides a mop bucket, which includes a mop bucket body 1. An opening 8 is provided on the upper surface of the mop bucket body 1, allowing the mop to be inserted vertically into the mop bucket body 1 in a folded state. The mop bucket also includes a water pump 2, a water delivery channel 3, a water storage chamber 4, and a pressure accumulator 5. The water pump 2 pressurizes water via a foot pedal 23. The two ends of the water delivery channel 3 are connected to the water pump 2 and the water storage chamber 4, respectively. The water delivery channel 3 delivers the pressurized water from the water pump 2 to the water storage chamber 4 and ejects it from the water outlet 41. The water storage chamber 4 is located inside the mop bucket body 1, and the cross-sectional area of ​​the water storage chamber 4 is larger than that of the water delivery channel 3. A water outlet 41 is provided on the side wall of the water storage chamber, located below the opening 8. The pressure accumulator 5 includes a housing 51, a first elastic element 52, and a second elastic element 53. A piston 53 and a first elastic element 52 are disposed within a housing 51. The first end of the housing 51 is connected to a water pump 2 via a water supply channel 3, and the second end of the housing 51 is connected to a water storage chamber 4 via the same water supply channel 3. The elastic coefficient of the first elastic element 52 is set such that when the water pump 2 pressurizes and delivers water, the first piston 53 moves away from its initial position under the pressure of the water, causing the first elastic element 52 to deform. When the water pump stops pressurizing, the first elastic element 52 drives the first piston 53 to displace, releasing the pressure and causing the first piston 53 to gradually return to its initial position. By installing a water pump 2 inside the mop bucket, the water pump 2 can pressurize and deliver clean water into the mop bucket body 1. When the mop is inserted into the mop bucket body 1, clean water is sprayed out through the water outlet 41 onto the surface of the mop to be cleaned, achieving the purpose of continuously cleaning the mop with flowing clean water and improving the cleaning effect of the mop.

[0099] Meanwhile, since both ends of the housing 51 of the accumulator 5 are connected to the water delivery channel 3, that is, the accumulator 5 divides the water delivery channel 3 into a part directly connected to the water pump 2 and a part directly connected to the water storage chamber 4, the water in the water delivery channel 3 will flow through the housing 51 of the accumulator 5. When the water pump 2 is in working condition, the water pressure in the water delivery channel 3 is relatively high, and the water pressure in the housing 51 is also relatively high. Under the action of water pressure, the first piston 53 leaves its initial position and is displaced, causing the first elastic element 52 to deform. Specifically, the first piston 53 is squeezed outward, the first elastic element 52 deforms and stores pressure, the space in the housing 51 that can hold water increases, and the water volume in the water supply channel 3 in the housing 51 increases. When the water pump 2 stops working, the water pressure in the water supply channel 3 and the housing 51 decreases, the first elastic element 52 rebounds inward to release the pressure, the elastic element drives the piston to move towards the initial position and gradually reset back to the initial position, the space in the housing 51 that can hold water decreases, the pressure in the housing 51 increases, and the water in the water storage chamber 4 that is connected to the housing 51 through the water supply channel 3 continues to be sprayed outward from the water outlet 41. Thus, when the water pump 2 stops working, the water in the water supply channel 3 can still be sprayed out through the water outlet 41, prolonging the spraying time of the water outlet 41 and increasing the spray volume of the water outlet 41, so that the mop can be rinsed with more water for a longer time, further improving the cleaning effect of the mop.

[0100] In this embodiment, as Figure 8 As shown, the opening has a lower hanging edge 81 extending vertically downwards from its edge. The lower hanging edge 81 has horizontally protruding ribs 82, with at least two ribs 82 on each edge. Specifically, in this embodiment, the lower hanging edge 81 is located below the wider side edges of the opening 8, and each lower hanging edge 81 has at least two ribs 82. By providing the lower hanging edge 81 and the ribs 82, it can be ensured that the mop is vertical and not tilted when inserted into the mop bucket body from the opening 8.

[0101] In this embodiment, except for the water outlet 41 and the location where the water storage chamber 4 connects with the water delivery channel 3, the water storage chamber 4 has good water tightness to maintain water pressure. That is to say, after the water from the water delivery channel 3 flows into the water storage chamber 4, it can only be sprayed out through the water outlet 41.

[0102] In this embodiment, as Figures 4-9As shown, the housing 51 of the pressure accumulator 5 has a connecting channel 54. Water flowing through the pressure accumulator 5 actually flows through the connecting channel 54 inside the housing; that is, the connecting channel 54 is the space inside the housing used to contain water. Water flows from the first end of the housing 51 through the connecting channel 54 to the second end of the housing 51. When the first piston 53 is in the initial position, the connecting channel 54 is closed; one end of the first elastic member 52 abuts against the first piston 53, and the other end abuts against the inner wall of the housing 51. When the first piston 53 leaves the initial position, the connecting channel 54 is opened, and water flows through the connecting channel 54. When the foot pedal 23 is stepped on to pressurize the water pump 2, the water pressure in the water delivery channel 3 increases, and the water pressure in the connecting channel 54 also increases. The first piston 53 is subjected to upward pressure and moves upward. The first elastic element 52 is compressed. At this time, the space inside the housing 51 for accommodating water increases. Since the water pump 2 continuously pumps water into the water delivery channel 3, the water is finally sprayed out from the water outlet 41, realizing the function of washing the mop with running water.

[0103] Due to the function of the pressure accumulator 5, after the foot pedal 23 is stopped, the water pump 2 stops pressurizing the water. The first elastic element 52 of the pressure accumulator 5 rebounds downward to release the pressure, and the first piston 53 also moves downward to gradually return to its initial position. The volume of the space inside the housing 51 used to hold water, i.e., the connecting channel 54, decreases, and the water pressure in the connecting channel 54 and the water delivery channel 3 increases, allowing the remaining water in the water storage chamber 4 to continue to spray out from the water outlet 41. The pressure accumulator 5 extends the spraying time of the water outlet 41 within the same foot pedal 23 time, improving the cleaning efficiency of the mop.

[0104] In this embodiment, the pressure storage device 5 is positioned above the water conveying channel 3, which facilitates its installation and maintenance. Of course, in other embodiments, the first elastic element 52 and the first piston 53 can also be positioned in other locations, as long as the first piston 53 of the pressure storage device 5 can move to change the size of the water-containing space in the water conveying channel 3 when the water pressure changes.

[0105] In this embodiment, as Figures 6-7 As shown, the connecting channel 54 inside the housing 51 also includes a tapering section 541. The cross-sectional area of ​​the tapering section 541 gradually decreases along the direction of water flow. The tapering section 541 is located close to the first end of the housing 51 and upstream of the first piston 53. By providing the tapering section 541 near the upstream of the pressure accumulator 5, the pressure at the pressure accumulator 5 is increased, thereby increasing the water pressure on the first piston 53 and improving the pressure accumulator effect of the pressure accumulator 5.

[0106] Specifically, in this embodiment, the end of the tapered portion 541 with a relatively larger channel cross-sectional area is close to the first end of the housing, while the end of the tapered portion 541 with a relatively smaller channel cross-sectional area extends to an upstream position below the first piston 53. Simultaneously, a second groove 56 is also provided on the bottom wall of the housing 51; specifically, the bottom wall of the housing 51 protrudes downwards to form the second groove 56.

[0107] Furthermore, such as Figure 4 and Figure 5 As shown, a limiting part 55 is provided inside the housing 51 to restrict the degree of freedom of movement of the first piston 53. Specifically, by providing the limiting part 55 on the inner circumference of the housing 51, the inner diameter of the upper half of the housing 51 is set to be equal to the outer diameter of the first piston 53, and the outer diameter of the lower half of the housing 51 is set to be smaller than the outer diameter of the first piston 53. This results in a limiting part 55 being formed on the inner circumference of the boundary between the lower and upper halves of the housing 51, allowing the first piston 53 to move only in the lower half of the housing 51, thus preventing the first piston 53 from moving excessively downward.

[0108] In this embodiment, the water nozzle 41 is positioned at a height within the mop bucket body 1 such that when the mop is fully inserted into the mop bucket body 1, the water sprayed from the water nozzle 41 can reach the upper end of the mop's cleaning surface. By setting the height of the water nozzle 41 so that water can reach the upper end of the mop's cleaning surface, the water on the mop flows downwards from the top, thereby making the mop's cleaning surface more thoroughly cleaned.

[0109] In this embodiment, as Figure 4 and Figure 8 As shown, the cross-sectional area of ​​the water storage chamber 4 is larger than that of the water conveyance channel 3. The water outlet 41 is located on the side wall of the water storage chamber 4, which has a larger cross-sectional area, allowing the water outlet 41 to cover a wider area. Specifically... Figure 4 As shown, the water supply channel 3 is a circular water pipe, and the water storage chamber 4 is a cuboid cavity. Multiple water nozzles 41 are located on the side wall of the water storage chamber 4, and these multiple nozzles 41 are simultaneously connected to the water storage chamber 4. The multiple water nozzles 41 are evenly distributed along the width direction of the opening 8. By providing multiple water nozzles 41 distributed along the width direction of the surface to be cleaned on the side wall of the water storage chamber 4, the coverage area of ​​the water nozzles 41 on the surface to be cleaned on the mop can be increased, ensuring that all parts of the mop's surface to be cleaned are effectively cleaned.

[0110] Specifically in this embodiment, such as Figure 4As shown, multiple water nozzles are distributed along the width of the surface of the mop to be cleaned and are set at the same height. The water nozzles 41 extend horizontally. By extending the water nozzles 41 horizontally, the water is sprayed horizontally from the water nozzles 41 and flows downward, resulting in a better cleaning effect on the mop.

[0111] Of course, in other embodiments, the water outlet 41 may also extend upward or downward at an angle along the water flow direction, and there may be only one water outlet or multiple water outlets 41 arranged in multiple rows along the height direction. In more embodiments, the water delivery channel 3 may also be a pipe of other shapes or an integrally formed channel inside the mop bucket, which will not be elaborated here.

[0112] In this embodiment, as Figure 4 As shown, the water pump 2 is located at the bottom of the mop bucket. The water pump 2 pumps water upward to the pressure storage device 5 through the water supply channel 3. The water is sprayed out from the water outlet 41, which is at the same height as the pressure storage device 5, thereby cleaning the mop.

[0113] Specifically in this embodiment, such as Figures 1-2 As shown, the water pump 2 is entirely located at the bottom of the mop bucket body. The water pump includes a foot pedal 23, which is located on the lower outer side of the mop bucket body 1 and protrudes outward from the mop bucket body 1 by a certain distance. The foot pedal 23 achieves the function of pressurizing and pumping water by lever. The fulcrum of the foot pedal 23 is located on the side close to the water pump 2, thereby saving the user effort when using the foot pedal 23. By setting the foot pedal 23 on the lower outer side of the mop bucket body 1, it is convenient for the user to use the foot pedal 23 to deliver water into the mop bucket body 1.

[0114] Of course, in other embodiments, the foot pedal 23 can also be positioned anywhere on the outside of the mop bucket, as long as it is convenient for the user to step on it.

[0115] Specifically in this embodiment, such as Figure 4 and Figure 6As shown, the water pump 2 includes a pump body 21, a second piston 22, a foot pedal 23, and a second elastic member 24. The fulcrum of the foot pedal 23 is located on the outside of the mop bucket body. The pump body 21, the second piston 22, and the second elastic member 24 are all located inside the mop bucket body. The pump body 21 has a chamber inside. The second piston 22 and the second elastic member 24 are located in the chamber. The foot pedal 23 is connected to the second piston 22. Along the extension and retraction direction of the second elastic member 24, the two ends of the second elastic member 24 abut against the upper wall of the chamber and the second piston 22, respectively. When using the mop bucket, step on the foot pedal 23 downwards on the outside of the fulcrum. The outside of the foot pedal 23 moves downwards under the force, while the inside moves upwards, driving the second piston 22 to move and pump water in. The second elastic element 24 is compressed. When the foot pedal 23 is released, the second piston moves downwards under the action of the second elastic element 24, driving the inside of the foot pedal downwards. At the same time, the outside of the foot pedal 23 moves upwards, pressurizing the pumped water and delivering it to the water delivery channel 3. Finally, the water is sprayed out from the water outlet 41 to clean the mop.

[0116] Among them, such as Figure 2 and Figure 8 As shown, the foot pedal 23 is fixed by a foot pedal support frame 25 located on the outside of the mop bucket body. Specifically, the foot pedal support frame 25 includes a base plate 251 and two side plates 252. The two side plates 252 protrude upward relative to the base plate 251, and each side plate 252 has a mounting hole. The foot pedal 23 has two connecting posts 232 corresponding to the two mounting holes. The two connecting posts 232 are inserted into the mounting holes to install the foot pedal 23. The location of the connecting posts 232 of the foot pedal 23 is the fulcrum of the foot pedal 23. In this embodiment, the foot pedal support frame 25 and the mop bucket body are separate and connected by a connector. The base plate 251 of the foot pedal support frame 25 is flush with the bottom of the mop bucket body.

[0117] Of course, in other embodiments, the foot support frame can also be integrally formed with the mop bucket body, which will not be elaborated here.

[0118] Furthermore, in this embodiment, as Figures 1-3 As shown, the mop bucket body also has a clearance hole 103 for the foot pedal to extend into the interior of the mop bucket body. In the vertical direction, that is, the height direction of the clearance hole 103, the size of the clearance hole is larger than the thickness of the foot pedal, so that there is a gap between the foot pedal and the inner wall of the clearance hole 103. In the horizontal direction, that is, the width direction of the clearance hole 103, the size of the foot pedal support frame 25 is larger than the size of the clearance hole 103. By setting a gap between the foot pedal and the clearance hole 103, the foot pedal moves more smoothly when stepped on. By setting the size of the foot pedal support frame 25 to be larger than the size of the clearance hole 103, it is easier to connect the foot pedal support frame 25 to the mop bucket body.

[0119] Meanwhile, in this embodiment, such as Figure 2 As shown, the outer wall of the mop bucket body is recessed inward to form a receiving cavity 101. The water pump 2 is located below the receiving cavity 101, and the water delivery channel 3 is partially disposed within the receiving cavity 101. A through hole 102 is formed on the outer wall of the mop bucket body above the water pump 2 to allow the water delivery channel 3 to connect to the water pump 2. By recessing the outer wall of the mop bucket inward to form the receiving cavity 101 and placing the water delivery channel 3 within the receiving cavity 101, damage to the water delivery channel 3 can be effectively prevented. Furthermore, by providing the through hole 102 on the outer wall of the mop bucket body above the water pump 2, the water delivery channel 3 can be connected to the water pump through the through hole 102.

[0120] In this embodiment, as Figure 3 As shown, the end of the water pump 2 furthest from the water delivery channel 3 has an inlet 260, which connects the water pump 2 to the external pipeline. A filter cotton 7 is installed at the inlet 260. By installing the filter cotton 7 at the inlet 260, the cleanliness of the water delivered to the mop bucket is improved. At the same time, the filter cotton 7 filters impurities in the water from the external pipeline, preventing impurities from entering the water pump 2 and the water delivery channel 3, which could damage the water pump 2 or clog the water delivery channel 3.

[0121] Among them, such as Figure 3 As shown, an inlet 260 is formed at the end of the inlet pipe, and an outlet is formed at the end of the outlet pipe. The size of the inlet 260 is larger than the diameter of the inlet pipe. Specifically, the inlet pipe includes a horizontally arranged lead pipe 261 and a delivery pipe 262, allowing water to first enter the lead pipe 261 horizontally and then flow vertically through the delivery pipe 262 into the water pump. The lead pipe 261 and the delivery pipe 262 are connected with rounded corners; that is, the connection between the lead pipe 261 and the delivery pipe 262 has a rounded buffer angle. This rounded corner connection reduces water resistance at the pipe connection, allowing water to be transported upwards more effectively. Furthermore, by setting the size of the inlet 260 to be larger than the diameter of the inlet pipe, the water pump 2 can also pump water in more efficiently.

[0122] Furthermore, in this embodiment, the inlet pipe and outlet pipe 27 of the water pump are arranged radially on two relatively far sides of the water pump. Specifically, in this embodiment, as shown... Figure 6 As shown, the inlet pipe is located on the left side of the water pump, and the outlet pipe 27 is located on the right side of the water pump. Furthermore, the water inlet 260 of the water pump is lower than the outlet, meaning that the water inlet pipe of the water pump is lower than the outlet pipe 27.

[0123] In this embodiment, the mop bucket also includes a scraper 9, which is positioned such that when the mop is inserted into the body 1 of the mop bucket, the scraper is in contact with the surface of the mop to be cleaned. By setting the scraper 9 so that it is in contact with the surface of the mop to be cleaned, the user can squeeze out the water from the mop and scrape off the dirt when pulling the mop out of the mop bucket, without having to squeeze the mop dry by hand.

[0124] Specifically, the squeezing blade is positioned above the water nozzle 41. By positioning the squeezing blade above the water nozzle 41, it ensures that the surface of the mop to be cleaned is completely wrung dry after being wetted.

[0125] In this embodiment, as Figure 1 , Figure 4 and Figure 9 As shown, the opening 8 on the upper surface of the mop bucket has an arc-shaped portion on the side away from the water nozzle 41. The shape of the arc-shaped portion matches the shape of the mop handle 10. Of course, the side of the opening 8 near the water nozzle 41 matches the shape of the mop body. By providing an arc-shaped portion on the side of the opening 8 away from the water nozzle 41 that matches the shape of the mop, the opening 8 can guide the user to insert the mop into the mop bucket in the correct direction. When the user inserts the mop into the mop bucket in the correct direction, the surface of the mop body to be cleaned is close to and opposite the water nozzle 41 of the mop bucket, so that the water sprayed from the water nozzle 41 can better clean the mop.

[0126] Meanwhile, in this embodiment, such as Figure 4 As shown, the mop bucket body includes a bucket body and a bucket lid, which are detachably connected. An opening 8 for the mop to extend into the mop bucket body is formed on the upper surface of the bucket lid. The lower surface of the bucket lid has a protrusion 11 facing the bucket body, and the bucket body has a first groove 12 corresponding to the protrusion 11, in which the protrusion 11 can be inserted. By making the mop bucket body and lid detachable, it is more convenient to use. At the same time, the detachable connection between the bucket body and the bucket lid is achieved by the engagement of the protrusion 11 and the first groove 12, resulting in a simple and reliable structure.

[0127] In this embodiment, as Figure 6 As shown, a one-way valve 31 is installed in the water conveying channel. The one-way valve 31 is located near the outlet of the water pump. The one-way valve 31 limits the flow direction of water in the water conveying channel to flow from the outlet of the water pump to the storage chamber. By installing the one-way valve 31 in the water conveying channel, backflow of water in the water conveying channel and the storage chamber towards the inlet 260 is prevented.

[0128] In this embodiment, the cross-sectional area of ​​the inlet 260 is larger than the cross-sectional area of ​​the outlet nozzle. The cross-sectional area of ​​the outlet nozzle referred to in this embodiment is the total cross-sectional area of ​​all outlet nozzles; that is, when there are two or more outlet nozzles, the cross-sectional area refers to the sum of the cross-sectional areas of all outlet nozzles. By setting the cross-sectional area of ​​the inlet 260 to be larger than that of the outlet nozzle, the water pressure when water is sprayed out at the outlet nozzle can be increased, thus improving the cleaning effect on the mop.

[0129] Specifically, in this embodiment, the ratio of the cross-sectional area of ​​the water outlet to the cross-sectional area of ​​the water inlet 260 is defined as a, where a = 1 / 2.

[0130] Of course, in other embodiments, the ratio of the cross-sectional area of ​​the water outlet to the cross-sectional area of ​​the water inlet 260 can also be adjusted according to the actual situation. The value of a is in the range of 1 / 6≤a≤5 / 6. Within this range, the mop bucket has a better cleaning effect on the mop.

[0131] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
