Technical Field
[0001] This utility model relates to the field of mechanical technology, specifically to a water pumping mechanism for a clear water tank and its mop bucket. Background Technology
[0002] A mop bucket is a container specifically designed to clean and dry mops. It is usually equipped with a wringer, which makes it easier for users to wash and dry mops, thereby improving cleaning efficiency.
[0003] In existing mop buckets, the cleaning part is usually integrated into the bucket body. This structure makes the cleaning part impossible to remove, which makes mop bucket maintenance very inconvenient.
[0004] Chinese patent publication number CN221997776U discloses a rotary adjustable flat mop bucket for washing and dehydrating, comprising a bucket body, a squeezer, a transmission mechanism, and a water supply mechanism. The bucket body is provided with a washing and dehydrating section with a chamber and a clean water chamber. A bucket lid is fixed on the bucket body, and the bucket lid has an opening. The water supply mechanism includes a water pump set in the clean water chamber. The water pump is driven by the transmission mechanism. The bucket lid has a water inlet, and a water supply pipe is fixedly connected to the water pump. The water supply pipe is opposite to the water inlet. When the flat mop moves up and down, the water pump delivers clean water from the clean water chamber to the water inlet through the water supply pipe for washing the flat mop. The washing and dehydrating section can rotate relative to the bucket lid. The transmission mechanism and the water pump are fixedly connected to the washing and dehydrating section as a whole and can rotate together with the washing and dehydrating section.
[0005] When the washing and dehydration section rotates relative to the lid under force, the water supply pipe and the water inlet are misaligned, causing the water supply pipe to close or forming a backflow area between the water supply pipe and the lid.
[0006] However, in the aforementioned patent, the water supply mechanism is directly connected to the bucket, using the water in the bucket to clean the mop. This causes the water in the bucket to quickly turn into wastewater, which is not conducive to its long-term cleaning use. Utility Model Content
[0007] The first objective of this invention is to address the aforementioned problems in the existing technology by providing a compact and easy-to-use water pumping mechanism for a clear water tank.
[0008] The second objective of this invention is to provide a mop bucket employing the aforementioned water tank pumping mechanism.
[0009] To achieve the above objectives, the first objective of this utility model can be achieved through the following technical solution:
[0010] A water tank pumping mechanism includes a water tank with an internal cavity and an open top. It is characterized by further including an end cap, a pump assembly, and a drive assembly. The end cap is fastened to the water tank port. The side of the water tank is a contact portion for contacting a mop. The pump assembly is connected inside the water tank. The drive assembly is located on the side of the water tank, with one side extending out of the contact portion. The other side of the drive assembly is connected to the pump assembly. The inlet end of the pump assembly is located at the bottom of the water tank, and the outlet end of the pump assembly is located at the contact portion.
[0011] In the above-mentioned water tank pumping mechanism, the end cap includes a connecting part one and a connecting part two. The connecting part one is fastened to the upper port of the water tank, and the connecting part two is attached to the side of the water tank. The driving component is located at the connecting part two.
[0012] In the above-mentioned water tank pumping mechanism, one of the connecting parts has a through water injection hole and a cover that can be opened and closed at the water injection hole.
[0013] In the aforementioned water pumping mechanism for the clear water tank, the pump assembly includes a pump body, a piston, a water pipe, a water inlet, and a one-way structure. The pump body is U-shaped and has a cavity inside. The water inlet is located at the bottom of the U-shape of the pump body. The piston is located inside one end of the U-shape of the pump body. The lower end of the water pipe is connected to the other end of the U-shape of the pump body. The one-way structure is located at the connection between the water pipe and the pump body, and under the action of the one-way structure, water can only flow in the direction from the pump body to the water pipe.
[0014] In the above-mentioned clear water tank pumping mechanism, the unidirectional structure includes an annular protruding flange at the other end of the pump body's U-shape and a spherical sealing ball. In the initial state, the sealing ball abuts against the flange and keeps the other end of the pump body's U-shape sealed.
[0015] In the above-mentioned water pumping mechanism for the clear water tank, the pump body has a protruding water inlet section at the U-shaped bottom, the water inlet is located at the bottom of the water inlet section, the inside of the water inlet section is a cavity and the water inlet section communicates with the internal cavity of the pump body.
[0016] The aforementioned water pumping mechanism for the clear water tank also includes a spherical sealing ball 2, which tends to abut against the water inlet.
[0017] In the above-mentioned water tank pumping mechanism, the inner side of the water inlet section has an annular protruding baffle two, and the annular baffle two forms the above-mentioned water inlet at the lower end of the water inlet section. The inner side of the water inlet section has several vertically protruding guide ribs along its circumference, and the several guide ribs abut against the two sides of the sealing ball.
[0018] In the above-mentioned water pumping mechanism for the clear water tank, the pump body also has a limiting post. The limiting post is located directly above the water inlet. After the sealing ball 2 moves up and abuts against the limiting post, the sealing ball 2 is still within the water inlet section.
[0019] In the above-mentioned clear water tank pumping mechanism, the driving components include a driving wheel, a driven wheel, and a connecting rod. The driving wheel is axially fixed to the second connecting part and can rotate relative to the second connecting part. The driven wheel is axially fixed to the first connecting part and can rotate relative to the first connecting part. The upper end of the connecting rod is hinged to the edge of the driven wheel, and the lower end of the connecting rod is hinged to the piston. The driving wheel is connected to the driven wheel.
[0020] In the above-mentioned water pumping mechanism for the clear water tank, both the driving wheel and the driven wheel are gears, and the driving wheel meshes with the driven wheel.
[0021] In the above-mentioned water pumping mechanism for the clear water tank, the connecting part has a guide cavity with an internal cavity, and the contact part has several through water outlet holes. The upper end of the water pipe and the water outlet holes are connected to the guide cavity.
[0022] In the above-mentioned clear water tank pumping mechanism, a transparent cover plate is connected to one of the connecting parts, and the above-mentioned guide cavity is formed between the cover plate and the connecting part.
[0023] In the aforementioned water tank pumping mechanism, a lifting ring is hinged at one of the connecting parts.
[0024] In the above-mentioned water tank pumping mechanism, the lifting ring is U-shaped and the U-shaped port of the lifting ring is hinged to the outside of the connecting part.
[0025] The second objective of this utility model can be achieved through the following technical solution:
[0026] A mop bucket includes a water tank pumping mechanism, wherein the water tank pumping mechanism and the mop bucket are two independent parts and the water tank pumping mechanism can be drawn out from the mop bucket to replenish water separately.
[0027] In the aforementioned mop bucket, the mop bucket includes a bucket body with an internal cavity and an open top. A top plate is connected to the end of the bucket body, and the top plate has a through connecting hole. The connecting hole matches the water tank, which is connected through the connecting hole. The inner wall of the connecting hole has a recessed limiting notch, and the lifting ring abuts against the limiting notch.
[0028] Compared to existing technologies, this water tank pumping mechanism features an independent water tank that stores clean water. During use, the clean water flows steadily from the tank through a pump assembly to the contact area. Since the mop is in contact with the contact area during cleaning, the clean water effectively washes the mop. Because the water tank is an independent cavity, it ensures that only clean water is used throughout the cleaning process, resulting in excellent cleaning performance.
[0029] Meanwhile, the up-and-down movement of the mop causes the drive component to move accordingly, which in turn drives the water pump component, resulting in stable water output and further improving its stability. It can be seen that no additional operation is required during the mop washing process other than pulling the mop up and down within the bucket, making it easy to use.
[0030] In addition, in the initial state, the sealing ball 2 rests against the bottom of the water tank, ensuring a stable water intake for the pump. During maintenance, the clear water tank pumping mechanism can be disassembled independently, and after disassembly, the sealing ball 2 tends to seal the water inlet, preventing water leakage during maintenance and further improving its stability and applicability.

[0040] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 As shown, the water tank pumping mechanism includes a water tank 1 with an internal cavity and an open top, as well as an end cap 2, a pump assembly, and a drive assembly. The end cap 2 is fastened to the port of the water tank 1. The side of the water tank 1 is a contact part 1a for contacting a mop. The pump assembly is connected inside the water tank 1. The drive assembly is located on the side of the water tank 1, with one side of the drive assembly extending out of the contact part 1a. The other side of the drive assembly is connected to the pump assembly. The water inlet of the pump assembly is located at the bottom of the water tank 1, and the water outlet of the pump assembly is located at the contact part 1a.
[0042] The drive component is located at the contact portion of the water tank 1, so the drive component is passively activated when the mop passes through the contact portion 1a.
[0043] Since the drive assembly is connected to the pump assembly, the pump assembly moves along with the drive assembly during its operation. During operation, the pump assembly transports water from the bottom of the water tank 1 to the contact portion 1a.
[0044] In other words, the mop is subjected to a continuous flow of water as it passes through the contact part 1a, ensuring that the mop is cleaned stably.
[0045] After the end cap 2 is opened, water can be easily poured into the water tank 1. During normal use, the end cap 2 closes the upper part of the water tank 1.
[0046] The end cap 2 includes a first connecting part 2a and a second connecting part 2b. The first connecting part 2a is fastened to the upper port of the water tank 1, and the second connecting part 2b is attached to the side of the water tank 1. The drive component is located at the second connecting part 2b.
[0047] The connecting part 2a is used to fasten and seal the upper end of the water tank 1.
[0048] Connector 2b has two functions:
[0049] Firstly, sufficient space is provided for the contact part 1a, that is, the contact part 1a is located on the side of the connecting part 2b;
[0050] Secondly, it provides sufficient space for the drive component to be set up, and the drive component is also located at the contact part 1a, ensuring that the drive component can move stably as the mop passes through the contact part 1a.
[0051] The connecting part 2a has a through water injection hole 2a1 and a cover 3 that can be opened and closed at the water injection hole 2a1.
[0052] Open cover 3 when filling with water. Cover 3 is closed during normal operation.
[0053] The water pump assembly includes a pump body 4, a piston 5, a water pipe 6, a water inlet 7, and a one-way structure. The pump body 4 is U-shaped and has a cavity inside. The water inlet 7 is located at the bottom of the U-shape of the pump body 4. The piston 5 is located inside one end of the U-shape of the pump body 4. The lower end of the water pipe 6 is connected to the other end of the U-shape of the pump body 4. The one-way structure is located at the connection between the water pipe 6 and the pump body 4, and under the action of the one-way structure, water can only flow in the direction from the pump body 4 to the water pipe 6.
[0054] The drive assembly is connected to the piston 5. During the operation of the drive assembly, the piston 5 will move up and down inside the pump body 4.
[0055] During its movement, piston 5 ensures a continuous flow of water from inlet 7 into water pipe 6. The unidirectional structure also prevents backflow of water from within water pipe 6.
[0056] The unidirectional structure includes an annular protruding flange 4a at the other end of the U-shape of the pump body 4 and a spherical sealing ball 8. In the initial state, the sealing ball 8 abuts against the flange 4a and keeps the other end of the U-shape of the pump body 4 sealed.
[0057] When water flows from pump body 4 to water pipe 6, the sealing ball 8 stably disengages from the baffle 4a under the action of water flow, allowing water to flow continuously in that direction.
[0058] Conversely, when water flows from pump body 4 to water pipe 6, the sealing ball 8 abuts against the retaining edge 4a under the action of water flow and forms a seal to prevent water from flowing back.
[0059] The pump body 4 has a protruding water inlet section 4c at the U-shaped bottom. The water inlet 7 is located at the bottom of the water inlet section 4c. The water inlet section 4c is a cavity and communicates with the inner cavity of the pump body 4.
[0060] It also includes a spherical sealing ball 2 9, which tends to abut against the inlet 7.
[0061] The inner side of the water inlet section 4c has an annular protruding retaining edge 4b, and the annular retaining edge 4b forms the aforementioned water inlet 7 at the lower end of the water inlet section 4c. The inner side of the water inlet section 4c has several vertically protruding guide ribs 10 along its circumference, and the several guide ribs 10 all abut against the side of the sealing ball 9.
[0062] Because the pump body 4 is U-shaped and has a hollow interior, the internal space at the bottom of the pump body 4 is limited. The arrangement of the inlet section 4c provides sufficient space for the installation of the sealing ball 9 and the baffle 4b.
[0063] When the entire mechanism is installed inside the mop bucket, the sealing ball 29 rests against the bottom of the water tank 1 and is squeezed by the bottom of the water tank 1. The sealing ball 29 moves upward. At this time, there is a sufficient gap between the sealing ball 29 and the baffle 2 4b, and the water in the water tank 1 can stably enter the pump body 4 through the inlet 7.
[0064] The pump body 4 also has a limiting post 11, which is located directly above the water inlet 7. After the sealing ball 2 9 moves up and abuts against the limiting post 11, the sealing ball 2 9 is still in the water inlet section 4c.
[0065] The limiting post 11 is used to contact the upward-moving sealing ball 9 to prevent the sealing ball 9 from moving excessively upward under the action of water flow, and to ensure that the sealing ball 9 is always located within the water inlet section 4c.
[0066] The drive assembly consists of a drive wheel 12, a driven wheel 13, and a connecting rod 14. The drive wheel 12 is axially fixed to the connecting part 2b and can rotate relative to the connecting part 2b. The driven wheel 13 is axially fixed to the connecting part 2a and can rotate relative to the connecting part 2a. The upper end of the connecting rod 14 is hinged to the edge of the driven wheel 13, and the lower end of the connecting rod 14 is hinged to the piston 5. The drive wheel 12 is connected to the driven wheel 13.
[0067] As the mop moves up and down through the contact part 1a, the drive wheel 12 rotates, and the driven wheel 13 rotates with the drive wheel 12. Since the two ends of the connecting rod 14 are respectively hinged to the edge of the driven wheel 13 and the piston 5, the piston 5 can eventually move up and down reciprocally within the pump body 4, thereby achieving stable water output from the pump assembly.
[0068] Both the driving wheel 12 and the driven wheel 13 are gears, and the driving wheel 12 meshes with the driven wheel 13.
[0069] Gear transmission enables the connecting rod to move stably up and down.
[0070] The connecting part 2a has a guide cavity 2a2 with an internal cavity, and the contact part 1a has a plurality of through water outlet holes 19. The upper end of the water pipe 6 and the water outlet holes 19 are connected to the guide cavity 2a2.
[0071] Under the action of the guide cavity 2a2, the water in the water pipe 6 can be stably sprayed out from several water outlet holes 19 of the contact part 1a, thereby stably cleaning the mop passing through the contact part 1a.
[0072] A transparent cover plate 15 is connected to the connecting part 2a, and the aforementioned flow guide cavity 2a2 is formed between the cover plate 15 and the connecting part 2a.
[0073] Because the cover plate 15 is a transparent plastic plate, operators can directly observe the water flow.
[0074] A lifting ring 16 is hinged at the connecting part 2a.
[0075] The lifting ring 16 is U-shaped and the U-shaped port of the lifting ring 16 is hinged to the outside of the connecting part 2a.
[0076] The mechanism can be easily and independently retrieved using the lifting ring 16. Furthermore, the lifting ring 16 does not take up any space when swung to one side.
[0077] like Figure 7 As shown, this mop bucket includes the aforementioned water tank pumping mechanism. The water tank pumping mechanism and the mop bucket are two independent parts, and the water tank pumping mechanism can be drawn out from the mop bucket to replenish water separately.
[0078] The mop bucket includes a bucket body 17 with an internal cavity and an open top. A top plate 18 is connected to the end of the bucket body 17. The top plate 18 has a through connection hole 18a, which matches the water tank 1. The water tank 1 is connected through the connection hole 18a. The inner wall of the connection hole 18a has a recessed limiting notch 18a1, and the lifting ring 16 abuts against the limiting notch 18a1.
[0079] This water tank pumping mechanism has an independent water tank that stores clean water. During use, the clean water is steadily pumped from the tank to the contact point. Since the mop is in contact with the contact point during cleaning, the clean water effectively washes the mop. Because the water tank is an independent chamber, it ensures that only clean water is used throughout the cleaning process, resulting in excellent cleaning performance.
[0080] Meanwhile, the up-and-down movement of the mop causes the drive component to move accordingly, which in turn drives the water pump component, resulting in stable water output and further improving its stability. It can be seen that no additional operation is required during the mop washing process other than pulling the mop up and down within the bucket, making it easy to use.
[0081] In addition, in the initial state, the sealing ball 2 rests against the bottom of the water tank, ensuring a stable water intake for the pump. During maintenance, the clear water tank pumping mechanism can be disassembled independently, and after disassembly, the sealing ball 2 tends to seal the water inlet, preventing water leakage during maintenance and further improving its stability and applicability.
[0082] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
[0083] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
