Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to an independent water tank for a mop bucket and a mop bucket. Background Technology

[0002] Most flat mop buckets on the market operate without separating clean and dirty parts. They use a clean water zone to soak and clean the flat mop, and a squeegee zone is set on one side of the clean water zone. A squeegee is set on the top of the squeegee zone to wring out water. While wringing out water, the dirt on the mop head is removed, and the dirty water flows back to the clean water zone with the squeegee. This type of mop has a simple structure and is economical and practical.

[0003] Currently, many mop buckets now feature separate cleaning and wastewater separation, abandoning soaking for a new method of cleaning. Instead, they use a pump-driven spray system to clean the cleaning pad of the flat mop. Utility model patent CN217610946U discloses a mop cleaning device with wastewater drainage. This patent's solution uses a water supply mechanism to pump clean water from a storage chamber to spray and clean the mop. This ensures that the cleaning pad of the flat mop is cleaned with clean water, while wastewater flows into a wastewater chamber. A similar utility model patent is CN217987499U.

[0004] However, regardless of whether it's a non-dirty / clean separation mop bucket or a clean / dirty separation mop bucket that uses spray cleaning, the water tank is directly integrated into the mop bucket. While this structure is compact and less prone to leaks, it causes inconvenience for cleaning staff. When water needs to be filled, the entire mop bucket must be placed under the faucet, which is bulky and heavy, increasing the workload. Moreover, many households don't have a dedicated sink for rinsing mops, meaning the height from the faucet to the sink is less than the height of the mop bucket. In this case, filling the mop bucket requires tilting it to lower the height, resulting in incomplete filling. Holding the bucket with both hands to maintain its tilted position makes filling difficult.

[0005] To overcome the above problems, a mop bucket with an independent water tank and mop bucket is needed. Utility Model Content

[0006] The purpose of this utility model is to provide an independent water tank for a mop bucket and a mop bucket. The use of a detachable independent water tank for filling the bucket greatly reduces the difficulty of the filling operation and makes it more convenient for operators.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses an independent water tank for a mop bucket, which is used on a flat mop bucket and can be detachably installed on the mop bucket, comprising:

[0009] The main body of the water tank is used to hold clean water for cleaning the flat mop. It can be embedded into the installation interface of the mop bucket. It has a water inlet at the top and a water outlet at the bottom.

[0010] A water-locking component is provided on the water outlet structure and can close the water outlet structure when the water tank body is separated, and can connect the water outlet structure when the water tank body and the mop bucket are combined.

[0011] The independent water tank can be detachably connected to the flat mop bucket, greatly facilitating cleaning staff. This is the first time the applicant has proposed, researched, designed, and prototyped this feature in the industry. It has promising market prospects and is bound to generate new consumer interest.

[0012] Furthermore, the water tank body is in the shape of a long strip box, and the upper part of the water tank body is set as an upper platform with an increased cross-section. A front guide ridge and a rear guide ridge are vertically arranged on the front and rear outer sides of the water tank body, respectively. The upper platform vertically limits the water tank body on the mounting interface of the mop bucket body, and the front guide ridge and the rear guide ridge vertically guide the water tank body inserted into the mounting interface of the mop bucket body.

[0013] Furthermore, a handle hole is provided on the upper box platform that runs through the left and right sides.

[0014] Furthermore, it also includes a plug, wherein the water inlet is opened on the top plate of the upper tank platform, and the plug is installed on the water inlet.

[0015] The main body of the water tank is shaped like a long, narrow box, which makes it easy to lift with one hand and also serves as a partition to divide the cavity.

[0016] Furthermore, the water outlet structure is specifically a bottom connector pipe, which is connected to the bottom plate of the water tank body; the water-locking component is detachably and sealingly installed at the bottom end of the bottom connector pipe.

[0017] Furthermore, the water-locking assembly includes an outlet sleeve, a main sealing gasket, a core slide rod, and a compression spring. The top of the outlet sleeve is externally threaded and sealed in the threaded hole at the bottom of the bottom connector pipe. A partition is horizontally arranged in the middle hole of the outlet sleeve, and multiple water-permeable holes are evenly distributed around the circumference of the partition. The core slide rod is coaxially slidably connected in the guide hole in the middle of the partition. The main sealing gasket is installed at the top of the core slide rod and can block the water-permeable holes above it. The compression spring is sleeved on the bottom of the core slide rod, and the two ends of the compression spring abut against the bottom surface of the partition and the bottom platform of the core slide rod, respectively.

[0018] Furthermore, the main sealing gasket is a perforated cylindrical sealing gasket, and an annular groove is provided at the top of the core slide rod, with the central hole of the main sealing gasket engaging within the annular groove.

[0019] The water-locking component uses a unique compression spring to drive the main sealing gasket to close the water-permeable hole, which is beneficial for switching between the blocking and driving opening states.

[0020] This utility model also discloses a mop bucket, which is a mop bucket for use with a flat mop, and has an installation interface on the top for use with any of the above-mentioned independent water tanks.

[0021] Furthermore, the device includes a mop bucket body and a water pump assembly. The installation interface is centrally located at the top of the mop bucket body. The water tank body divides the inner cavity of the mop bucket body into a washing chamber and a drying chamber. The water storage chamber of the water pump assembly can be connected to the inner cavity of the water tank body through the water-locking assembly.

[0022] Furthermore, the water storage chamber of the pump assembly is located below the main body of the water tank, and a countersunk sleeve is provided on the housing of the water storage chamber, with a protrusion inside the countersunk sleeve that triggers the water-locking assembly.

[0023] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0024] This utility model relates to an independent water tank for mop buckets. By featuring a detachable water tank body that is separate from the mop bucket itself, filling the bucket is as simple as removing the tank body and placing it under the faucet. This avoids the need to transport the bulky, tall, and heavy entire mop bucket, reducing the intensity of mopping and facilitating smooth filling. The addition of a water-locking component to the water outlet structure controls the stored water, preventing spillage during transport and ensuring smooth water output during use, making it safer and more convenient. This utility model's independent water tank for mop buckets, with its detachable design, significantly reduces the difficulty of filling and makes it easier for workers.

[0025] Furthermore, the limiting mechanism of the upper platform allows for better vertical positioning of the water tank body. The guidance and limiting functions of the front and rear guide ribs facilitate the insertion of the water tank body into the mounting interface of the main tank, preventing lateral misalignment during use. The addition of a handle hole allows for one-handed gripping, facilitating easy removal and insertion of the water tank body. The addition of a plug enables the sealing and opening of the water inlet. The return force of the compression spring pushes the top core slide rod downwards, causing the bottom surface of the main sealing gasket to press firmly against the top surface of the partition, sealing all water permeable holes and effectively sealing the bottom opening of the water tank body's inner cavity. The addition of an O-ring to seal the top threaded connection gap of the outlet sleeve and the fit gap between the bottom end of the outlet sleeve and the mounting interface reduces water leakage. The main sealing gasket is easily disassembled and replaced by using the annular groove; by setting multiple layers of the annular steel plates inside the main sealing gasket, the rigidity of the main sealing gasket can be increased, and the secure clamping with the annular groove can be increased, reducing the risk of detachment.

[0026] This utility model relates to a mop bucket where the water tank body is inserted into a flat mop bucket with separate clean and dirty parts. The water tank body supplies water to the water storage chamber of the pump assembly, which then pumps clean water to spray onto the flat mop inserted into the cleaning chamber for cleaning. The water tank body is inserted from the top into the centrally located mounting interface, serving to separate the cleaning and drying chambers. By adding through holes, a front guide groove, and a rear guide groove, the water tank body can be limited in the left-right, front-back, and height directions, ensuring stable installation within the mounting interface and preventing detachment during use. Through a well-designed pump assembly shell shape, it limits the side walls of the water tank body while also receiving water on one side of the bottom, facilitating the transfer of clean water from the water tank body to the water storage chamber, thereby achieving pumped spray cleaning. By adding a countersunk sleeve, the outlet sleeve can be accommodated, positioned, and connected. By connecting the protruding post to the bottom hole of the countersunk sleeve via the crossbeam, the trigger core slide rod can be activated without obstructing the flow of clean water.

[0043] Example 1

[0044] like Figures 1-4 As shown, this utility model relates to an independent water tank for a mop bucket, used on a flat mop bucket, and can be detachably installed on the mop bucket, comprising:

[0045] The water tank body 1 is used to hold clean water for cleaning the flat mop. It can be embedded into the mounting interface of the mop bucket. The volume and height of the water tank body 1 are significantly smaller than those of the mop bucket. The water tank body 1 has a water inlet at the top and a water outlet at the bottom. The water tank body 1 is a one-piece injection-molded plastic tank. Water is filled through the water inlet and drained through the water outlet.

[0046] A water-locking component is installed on the water outlet structure and can seal the water outlet structure when the water tank body 1 is separated, preventing water leakage during filling and handling. The water-locking component can connect the water outlet structure when the water tank body 1 is connected to the mop bucket, thereby allowing water from the water tank body 1 to be output to the mop bucket.

[0047] By designing a detachable water tank body 1 that is independent of the mop bucket, water can be added simply by removing the water tank body 1 and placing it under the faucet. This avoids the need to transport the bulky, tall, and heavy entire mop bucket, reducing the intensity of mopping and facilitating smooth water filling. The addition of a water-locking component to the water outlet structure controls the stored water, preventing spillage during transport and ensuring smooth output during use, making it safer and more convenient. This utility model utilizes a detachable, independent water tank for the mop bucket, significantly reducing the difficulty of filling and simplifying the process for operators.

[0048] In one specific implementation of this embodiment, such as Figures 1-4 As shown, the water tank body 1 is a long, narrow box shape, facilitating insertion and assembly. The upper part of the water tank body 1 is configured as an upper platform 101 with an enlarged cross-section. Front guide ribs 103 and rear guide ribs 104 are vertically arranged on the front and rear outer sides of the water tank body 1, respectively. The upper platform 101 vertically limits the water tank body 1 to the mounting interface of the mop bucket body 6, while the front guide ribs 103 and rear guide ribs 104 vertically guide the water tank body 1 into the mounting interface of the mop bucket body 6.

[0049] The upper platform 101 provides better vertical positioning of the water tank body 1; the front guide 103 and rear guide 104 provide guidance and limitation, making it easy to insert the water tank body 1 into the installation interface of the tank body 6, and preventing the water tank body 1 from shifting left or right during use.

[0050] Specifically, such as Figure 1 and Figure 2 As shown, a handle hole 105 is provided on the upper platform 101, extending from left to right. The main body 1 of the water tank is a horizontally arranged elongated hole.

[0051] Specifically, such as Figure 1 and Figure 2 As shown, the independent water tank for the mop bucket of this utility model also includes a plug 10, and the water inlet is opened on the top plate of the upper tank platform 101, and the plug 10 is installed on the water inlet.

[0052] Specifically, such as Figure 1 and Figure 2 As shown, the plug 10 is a rubber plug, and the plug 10 is opened and closed by inserting and removing the rubber plug body.

[0053] By adding a handle hole 105, it is possible to grip with one hand, which makes it easier to take out and insert the water tank body 1; by adding a plug 10, the water inlet can be blocked and opened.

[0054] In one specific implementation of this embodiment, such as Figures 1-3As shown, the water outlet structure is specifically a bottom connector pipe 102, the root of which is integrally connected to the bottom plate of the water tank body 1. The water-locking component is detachably and sealingly installed at the bottom end of the bottom connector pipe 102.

[0055] Obviously, the water outlet structure can also be a water outlet hole, and the water-locking component can be detachably and sealingly installed on the water outlet hole. Similar simple replacement methods all fall within the protection scope of this utility model.

[0056] Specifically, such as Figures 1-4 As shown, the water-locking assembly includes an outlet sleeve 2, a main sealing gasket 3, a core sliding rod 4, and a compression spring 5. The top of the outlet sleeve 2 is externally threaded and sealed in the threaded hole at the bottom of the bottom connector pipe 102. A partition is horizontally arranged in the middle hole of the outlet sleeve 2, and multiple water-permeable holes 201 are evenly distributed around the circumference of the partition. The core sliding rod 4 is coaxially slidably connected in the guide hole in the middle of the partition. The main sealing gasket 3 is installed at the top of the core sliding rod 4 and can seal all the water-permeable holes 201 from above. The compression spring 5 is coaxially sleeved at the bottom of the core sliding rod 4, with its two ends abutting against the bottom surface of the partition and the base of the core sliding rod 4, respectively.

[0057] The top core slide rod 4 is pushed downward by the restoring force of the compression spring 5, which in turn causes the bottom surface of the main sealing gasket 3 to press against the top surface of the partition plate, thereby sealing all the water permeable holes 201 and effectively sealing the bottom opening of the inner cavity of the water tank body 1.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, an O-ring is provided at the root of the external thread at the top of the outlet sleeve 2, and an O-ring is also installed in the sealing groove at the bottom of the outlet sleeve 2.

[0059] By adding an O-ring to seal the top threaded connection gap of the outlet sleeve 2 and the fitting gap between the bottom end of the outlet sleeve 2 and the installation interface, the leakage of clean water can be reduced.

[0060] Specifically, such as Figure 3 and Figure 4 As shown, the main sealing gasket 3 is a perforated cylindrical sealing gasket, and the top end of the core slide rod 4 has an annular groove, into which the central hole of the main sealing gasket 3 is engaged. The top end of the core slide rod 4 is set as a pointed tip.

[0061] Specifically, the main sealing gasket 3 is a composite gasket of rubber and circular steel plate, wherein multiple layers of the circular steel plate are vulcanized in the rubber material.

[0062] By using the annular groove to mount the main sealing gasket 3, it is easy to disassemble and replace; by setting multiple layers of the annular steel plates inside the main sealing gasket 3, the rigidity of the main sealing gasket 3 can be increased, and the secure mounting with the annular groove can be increased, reducing the risk of falling off.

[0063] In summary, this utility model of an independent water tank for a mop bucket, by setting a detachable water tank body 1 that is independent of the mop bucket, allows for easy filling by simply removing the water tank body 1 and placing it under the faucet. This avoids the need to transport the entire large, tall, and heavy mop bucket, reducing the intensity of mopping work and facilitating smooth filling. The addition of the water-locking component to the water outlet structure controls the stored water, preventing leakage during transport and ensuring smooth output during use, making it safer and more convenient. This utility model's independent water tank for a mop bucket, using a detachable independent water tank for filling, greatly reduces the difficulty of filling operations and facilitates workers. Furthermore, the upper platform 101 provides better vertical positioning of the water tank body 1; the front guide 103 and rear guide 104 facilitate the insertion of the water tank body 1 into the mounting interface of the bucket body 6, and prevent lateral misalignment of the water tank body 1 during use. By adding a handle hole 105, it is possible to grip with one hand, thus facilitating the removal and insertion of the water tank body 1; by adding a plug 10, the water inlet can be sealed and opened. The restoring force of the compression spring 5 pushes the top core slide rod 4 downwards, thereby causing the bottom surface of the main sealing gasket 3 to press firmly against the top surface of the partition, thus sealing all the water permeable holes 201 and effectively sealing the bottom opening of the inner cavity of the water tank body 1. By adding an O-ring to seal the top threaded connection gap of the outlet sleeve 2 and the mating gap between the bottom end of the outlet sleeve 2 and the installation interface, water leakage can be reduced. The use of the annular groove to mount the main sealing gasket 3 facilitates disassembly and replacement; by setting multiple layers of the annular steel plates inside the main sealing gasket 3, the rigidity of the main sealing gasket 3 can be increased, as well as the secure mounting with the annular groove, reducing the risk of detachment.

[0064] Example 2

[0065] like Figures 5-10 As shown, this utility model also discloses a mop bucket, which is a mop bucket for use with a flat mop, and has an installation interface on the top that cooperates with the independent water tank described in any of the above embodiments.

[0066] In one specific embodiment of this utility model, such as Figures 5-10 As shown, the mop bucket of this utility model includes a mop bucket body 6 and a water pump assembly 9. The installation interface is centrally located at the top of the mop bucket body 6. The water tank body 1 divides the inner cavity of the mop bucket body 6 into a washing cavity 7 and a drying cavity 8. The water storage cavity of the water pump assembly 9 can be connected to the inner cavity of the water tank body 1 through the water locking assembly.

[0067] The water tank body 1 is first inserted into the flat mop bucket with clean and dirty parts separated. The water tank body 1 supplies water to the water storage chamber of the water pump assembly 9, which then pumps clean water to spray onto the flat mop inserted into the cleaning chamber 7 for cleaning. Moreover, the water tank body 1 is inserted from the top into the centrally located installation interface, and the water tank body 1 serves to separate the cleaning chamber 7 and the drying chamber 8.

[0068] Specifically, such as Figures 5-10 As shown, the installation interface includes a through-hole 601, a front guide groove 602, and a rear guide groove 901. The through-hole 601 is centrally located on the top plate of the tank body 6, with its outline conforming to the outer contours of the middle and bottom of the tank body 1. The bottom surface of the upper platform 101 presses against the through-hole 601. The front guide groove 602 is located on the top of the front side wall of the tank body 6, and the front guide protrusion 103 slides within it. The rear guide groove 901 is located on the outer wall of the pump assembly 9 housing, and the rear guide protrusion 104 slides within it.

[0069] By adding a through hole 601, a front guide groove 602, and a rear guide groove 901, the water tank body 1 can be limited in the left, right, front, back, and height directions, ensuring that the water tank body 1 is stably installed in the installation interface and will not fall off during use.

[0070] Specifically, such as Figures 8-10 As shown, the housing of the water pump assembly 9 is an inverted L-shape and is vertically installed in the middle of the rear side wall of the tank body 6. The water storage chamber of the water pump assembly 9 is located at the bottom and is supported below the water tank body 1. A countersunk sleeve 902 is provided on the top plate of the housing of the water storage chamber, and a protrusion 903 for triggering the water-locking assembly is provided inside the countersunk sleeve 902.

[0071] By reasonably setting the shell shape of the water pump assembly 9, it can limit the side wall of the water tank body 1 while also receiving water on one side of the bottom surface of the water tank body 1, so that clean water can be transferred from the water tank body 1 to the water storage chamber, thereby realizing pumping and spraying cleaning.

[0072] Specifically, such as Figure 10 As shown, the outlet sleeve 2 of the water-locking assembly can be coaxially inserted into the countersunk sleeve 902. The protruding post 903 can push the core slide rod 4 upward. The core slide rod 4 overcomes the restoring force of the compression spring 5 and slides upward along the guide hole of the partition. As a result, the main sealing gasket 3 disengages from the top surface of the partition, and the water permeable hole 201 opens. Clean water flows from the inner cavity of the water tank body 1 into the water storage cavity of the pump assembly 9.

[0073] Specifically, such as Figure 10As shown, the bottom of the protruding post 903 is connected to the edge of the bottom hole of the countersunk sleeve 902 via a crossbeam. The protruding post 903, the crossbeam and the countersunk sleeve 902 are integrally injection molded on the housing of the pump assembly 9.

[0074] By adding a countersunk sleeve 902, the outlet sleeve 2 can be accommodated, positioned, and connected. By connecting the protruding post 903 to the bottom hole of the countersunk sleeve 902 by the crossbeam, the trigger core slide rod 4 can be triggered without obstructing the flow of clean water.

[0075] The working principle of this mop bucket is as follows: When water needs to be filled, grasp the handle hole 105 with one hand and then take out the water tank body 1 through the through hole 601. Open the plug 10, align the water inlet with the faucet to start filling with water, and after filling with water, reseal the plug 10. During water filling and hand movement, the restoring force of the compression spring 5 pushes the top core slide rod 4 downward, thereby causing the bottom surface of the main sealing gasket 3 to press firmly against the top surface of the partition, thus sealing all the water holes 201 and sealing the bottom opening of the inner cavity of the water tank body 1, thereby reducing the leakage of clean water. Reinstall the water tank body 1, with the bottom end of the water tank body 1 passing through the through hole 601, the front guide protrusion 103 inserted into the front guide groove 602, and the rear guide protrusion 104 inserted into the rear guide groove 901. Press down on the water tank body 1 until the bottom surface of the upper tank platform 101 presses against the through hole 601. During this process, the protruding post 903 pushes the core slide rod 4 upward, and the core slide rod 4 overcomes the restoring force of the compression spring 5 and slides upward along the guide hole of the partition. This causes the main sealing gasket 3 to detach from the top surface of the partition, and the water permeable hole 201 opens. The plug 10 is opened to prevent negative pressure from forming inside the water tank body 1. Clean water flows from inside the water tank body 1 into the water storage chamber of the pump assembly 9, providing clean water for spraying and cleaning the flat mop.

[0076] In summary, this utility model relates to a mop bucket where the water tank body 1 is inserted into a flat mop bucket with separate clean and dirty parts. The water tank body 1 supplies water to the water storage chamber of the pump assembly 9, which then pumps clean water to spray onto the flat mop inserted into the cleaning chamber 7 for cleaning. Furthermore, the water tank body 1 is inserted from the top into the centrally located installation interface, serving to separate the cleaning chamber 7 from the drying chamber 8. By adding a through hole 601, a front guide groove 602, and a rear guide groove 901, the water tank body 1 can be limited in the left-right, front-back, and height directions, ensuring stable installation within the installation interface and preventing it from falling off during use. By rationally designing the shell shape of the pump assembly 9, it not only limits the sidewalls of the water tank body 1 but also receives water on one side of the bottom surface of the water tank body 1, facilitating the transfer of clean water from the water tank body 1 to the water storage chamber, thereby achieving pumped spray cleaning. By adding a countersunk sleeve 902, the outlet sleeve 2 can be accommodated, positioned, and connected. By connecting the protruding post 903 to the bottom hole of the countersunk sleeve 902 by the crossbeam, the trigger core slide rod 4 can be triggered without obstructing the flow of clean water.
