Air-inflated water spray mop bucket

Abstract

This invention discloses an air-injection and water-spraying mop bucket, relating to the field of mop buckets. This mop bucket features independent clean water and wastewater chambers. Clean water is stored in the clean water chamber, while wastewater from mop washing remains in the wastewater chamber, preventing mixing and effectively avoiding contamination of the clean water by the wastewater, thus improving water resource utilization. Furthermore, this mop bucket uses a first air pump to drive the water spraying device. Since it eliminates the need for electrical components and batteries, it effectively avoids damage to electrical components from water, extending the device's lifespan and reducing operating costs.

Description

Technical Field

[0001] This invention relates to the field of mop buckets, and in particular to a mop bucket that sprays water for cleaning. Background Technology

[0002] Existing spray mop buckets add a spray device to the traditional mop bucket to assist in cleaning the mop. They generally use electrical components to control the spray device, automatically spraying water during cleaning. Compared to traditional mop buckets, spray mops offer a more convenient, faster, and more effective way to clean the mop. However, existing spray mop buckets still have the following drawbacks:

[0003] 1) Electrical components are easily damaged by water, resulting in a short lifespan for the spray mop;

[0004] 2) Batteries are generally used as the power source, but battery wear is significant and the cost of use is high;

[0005] 3) Clean water and sewage are mixed together, resulting in low water resource utilization;

[0006] Therefore, improving the water-spraying mop bucket, which has a long service life, low operating cost, and high water resource utilization rate, has become an urgent problem to be solved. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The purpose of this invention is to provide a mop bucket with a long service life, low operating cost, and high water resource utilization rate for air-spraying and water-cleaning.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-9As shown, the mop bucket for air-spraying and water-cleaning provided in this embodiment includes: a bucket body, which has an independent clean water chamber 4 and a receiving chamber inside, and a bucket opening at the top; a bucket lid 1, which is used to seal the bucket opening and is detachably connected to the top of the bucket body, and has an opening 9 that matches the shape of the mop 58 so that the mop 58 can be inserted into the receiving chamber; a limiting component, which is disposed in the receiving chamber, including a first connecting frame 6 and a plurality of locking tongues 7 arranged along the length direction of the first connecting frame 6, one end of each locking tongue 7 is connected to the first connecting frame 6 through a first elastic member 8, and the other end is disposed below the opening 9 so that the bottom end of the mop 58 abuts against the locking tongue 7 after passing through the opening 9. The first elastic member is specifically a spring. A limiting plate 10 is disposed in the receiving chamber along the height direction of the receiving chamber, and a plurality of limiting grooves 11 are arranged side by side on the limiting plate 10. The grooves 11 extend from the top of the limiting plate 10 along the height direction of the limiting plate 10 to the bottom of the limiting plate 10, and the limiting grooves 11 correspond one-to-one with the locking tongues 7. One locking tongue 7 is slidably set in one limiting groove 11. The function of the limiting groove 11 is to limit the locking tongue 7 to slide only along the height direction of the receiving cavity. The limiting groove 11 ensures the stability of the locking tongue 7 as it moves up and down with the mop 58. The first air pump 12 is set in the receiving cavity, and its first air pump rod 13 is fixedly connected to the first connecting frame 6. The water spraying device for spraying water onto the mop 58 is set in the receiving cavity. The water storage tank 14 is set in the receiving cavity. The clean water chamber 4 is connected to the water storage tank 14 to supply water to the water storage tank 14. The first air outlet of the first air pump 12 is connected to the water storage tank 14 to inflate the water storage tank 14. The water storage tank 14 is connected to the water spraying device to supply water to the water spraying device. The first air pump 12 of this air-inflating and water-spraying mop bucket inflates air into the water storage tank 14, driving the spraying device to spray water. Compared with electrically driven spraying devices, this air-inflating and water-spraying mop bucket does not require electrical components, effectively avoiding damage to these components from water. It also has a longer lifespan and lower operating costs because it does not require batteries. Furthermore, the wastewater generated from washing the mop 58 is retained in the receiving cavity, while clean water is stored in the clean water cavity 4. The clean water cavity 4 and the receiving cavity are independent of each other, effectively preventing wastewater from contaminating all the clean water, thus greatly improving water resource utilization.

[0037] In actual use, initially, the mop 58 is inserted upright into the container cavity from the opening 9. Then, the mop 58 is moved down until the bottom of the mop 58 abuts against the top of the locking tongue 7. The air pump starts and begins to pump air as the mop 58 is pressed down. The mop 58 continues to be pressed down until the inclined surface of the locking tongue 7 touches the bottom surface of the limiting groove 11. The locking tongue 7 compresses the spring and retracts backward along the inclined surface. The locking tongue 7 disengages from the limiting groove 11. The first air pump rod 13 of the first air pump 12 returns to its original position due to the rebound of the internal spring, completing one cycle of air pumping. The locking tongue 7 resets synchronously with the first air pump rod 13. The mop 58 continues to be pressed down until it is completely contained in the container cavity and then pulled back, completing the entire operation cycle. The second and third cycles of operation continue. After the first air pump 12 fills the water tank 14 with sufficient air pressure, the water spraying device starts to spray water. The mop 58 is continuously pulled out, and the water spraying device continuously sprays water to clean the mop 58. It should be noted that initially, the first air pump rod 13 of the first air pump 12 is connected to the first connecting frame 6. The weight of the first connecting frame 6 is supported on the first air pump rod 13, which in turn is supported on the internal spring of the first air pump 12. After the mop 58 applies pressure to the locking tongue 7, the pressure on the locking tongue 7 is transmitted to the first air pump rod 13 through the first connecting frame 6, and finally applied to the internal spring of the first air pump 12, causing the internal spring of the first air pump 12 to compress. The first air pump rod 13 moves down, and the first air pump 12 begins to pump air. The structure of the first air pump 12 is prior art and will not be described in detail here.

[0038] In this embodiment, for ease of cleaning the tub, such as Figure 1 As shown, the bucket body includes an upper bucket 2 and a lower bucket 3 that are stacked vertically and detachably connected. The upper bucket 2 has an opening at its top. A first partition 15 is provided inside the upper bucket 2, dividing the interior of the upper bucket 2 into an independent clean water chamber 4 and a first cavity 5. A second cavity 16 is provided inside the lower bucket 3 corresponding to the position of the first cavity 5. The first cavity 5 and the second cavity 16 are connected to form a receiving cavity. The limiting component and the water spraying device are both located in the first cavity 5, and the water storage tank 14 is located in the second cavity 16. Specifically, the bottom end of the limiting plate 10 is flush with the bottom end of the first cavity 5, and the top end is flush with the initial height of the locking tongue 7.

[0039] In this embodiment, in order to improve the sliding stability of the first connecting frame 6, the mop bucket for air-spraying and cleaning also includes a guide post 17, which is disposed in the first cavity 5 along the height direction of the first cavity 5. The first connecting frame 6 is perpendicular to the guide post 17 and is slidably connected to the guide post 17.

[0040] In this embodiment, as Figure 3As shown, the mop bucket for air-spraying and water-cleaning also includes a functional separation device, which includes a first button 18, a self-locking latch switch 19, a second connecting bracket 20, a first valve 21 for releasing air, and a second valve 22 for inlet water. The first button 18 is located on the bucket lid 1 and is fixedly connected to the top of the guide post 17. The self-locking latch switch 19 is located at the bottom of the first cavity 5 and is fixedly connected to the bottom of the first cavity 5. The bottom of the guide post 17 is provided with a fastening part 23 that matches the self-locking latch switch 19. The second connecting bracket 20 is located at the lower end of the guide post 17. The first air outlet of the first air pump 12 is connected to the second air outlet of the first air pump 12. A first switching valve 21 is connected, and the clear water chamber 4 is connected to the water storage tank 14 through a second switching valve 22. One end of the second connecting bracket 20 is fixedly connected to the first valve core 27 of the first switching valve 21, and the other end is fixedly connected to the second valve core 38 of the second switching valve 22. In the first state, pressing the first button 18 causes the guide post 17 to move down to the latching part 23 and latch into the self-locking door latch switch 19, opening the first switching valve 21 and closing the second switching valve 22. In the second state, pressing the first button 18 again causes the latching part 23 to separate from the self-locking door latch switch 19, the guide post 17 to move up and reset, closing the first switching valve 21 and opening the second switching valve 22. It should be noted that the self-locking door latch switch 19 and its matching latching part 23 are existing technologies, and their specific structures will not be described in detail. For example, the DL-9 model self-locking door latch switch 19 of the Heying brand can be used.

[0041] like Figures 4-6As shown, the first switching valve 21 includes a first valve body 24, a second elastic element 25, a first sealing ring 26, and a first valve core 27. The second elastic element 25 is specifically a spring. The first valve body 24 has a first through hole 28, a second through hole, and a third through hole 30 that are coaxial and connected in sequence. The diameter of the second through hole is smaller than the diameter of the first through hole 28, and the diameter of the third through hole 30 is larger than the diameter of the first valve core 27. The end of the first valve core 27 away from the second connecting bracket 20 passes through the first through hole 28, the second through hole, and the third through hole 30 in sequence. A first annular flange 31 is provided on the first valve core 27. A second elastic element 25 is sleeved on the first valve core 27. The first annular flange 31 and the second elastic element 25 are both disposed in the first through hole 28. One end of the second elastic element 25 abuts against the first annular flange 31 and the other end abuts against one end of the second through hole. A first sealing ring 26 is sleeved on the first valve core 27. The first sealing ring 26 is disposed in the third through hole 30, and the outer diameter of the first sealing ring 26 is larger than the diameter of the third through hole 30. The third through hole 30 is connected to the first air outlet of the first air pump 12. In the initial stage of actual use, the upper end face of the first sealing ring 26 abuts against the end of the third through hole 30 away from the second through hole. The first sealing ring 26 seals the gap between the third through hole 30 and the first valve core 27, and the first switch valve 21 is in the closed state. When the first valve core 27 moves down with the guide post 17, the second elastic element 25 is compressed, the first sealing ring 26 moves down with the first valve core 27, the gap between the third through hole 30 and the first valve core 27 is opened, and the first switch valve 21 is in the open state.

[0042] like Figure 4 , Figure 5 as well as Figure 7As shown, the second switching valve 22 includes a second valve body 32, a valve seat 33, a cross support column 34, a spherical support block 35, a second sealing ring 36, a third elastic element 37, and a second valve core 38. The third elastic element 37 is specifically a spring. The second valve body 32 has a fourth through hole 39 inside, and the valve seat 33 has a fifth through hole inside. The fourth through hole 39 and the fifth through hole are connected. The cross support column 34 is disposed in the fifth through hole, and the axis of the cross support column 34 coincides with the axis of the fifth through hole. The cross support column 34 is fixedly connected to the side wall of the fifth through hole. Specifically, the cross support column 34 includes a central column and four side plates. The four side plates are evenly arranged along the circumference of the central column, and each side plate is arranged along the height direction of the central column. Water flow is formed between any adjacent side plates. The flow channel and spherical support block 35 are fixed to the top of cross support column 34. A second flange 40 and a third flange 41 are respectively provided on the outer wall and bottom end of the second valve core 38. A second sealing ring 36 is slidably fitted onto the second valve core 38 and is positioned between the second flange 40 and the third flange 41. The outer diameter of the second sealing ring 36 is the same as the diameter of the fourth through hole 39. A groove is formed by the recess at the bottom end of the second valve core 38. One end of the third elastic member 37 abuts against the bottom end of the groove, and the other end abuts against the spherical support block 35. Multiple first notches 42 are provided circumferentially on the second flange 40, and multiple second notches 43 communicating with the interior of the groove are provided circumferentially on the side wall of the groove. The first notches 42 and second notches 43 correspond one-to-one. Specifically, in this embodiment, the second notches 43 extend upwards along the bottom end of the groove. In actual use, initially, the lower end face of the second sealing ring 36 abuts against the upper end face of the third flange 41. The water flows along the gap between the second valve core 38 and the fourth through hole 39 and the first notch 42 to the second notch 43, and enters the groove through the second notch 43. Finally, it falls from the groove to the fifth through hole and flows into the water storage tank 14 through the flow channel between the side plates of the cross support column 34. The guide column 17 moves down, and the second valve core 38 moves down synchronously. The third elastic element 37 is compressed under the action of the bottom surface of the groove and the spherical support block 35. At the same time, the second sealing ring 36 moves up relative to the second valve core 38 under the action of the friction force of the side wall of the fourth through hole 39 until it abuts against the lower end face of the second flange 40. At this time, the second sealing ring 36 seals the gap between the second valve core 38 and the side wall of the fourth through hole 39, and the second sealing ring 36 is located above the second notch 43. The water flow cannot reach the second notch 43, and the second switch valve 22 is closed.

[0043] It should be noted that the first switching valve 21 and the second switching valve 22 are not limited to the above structure. Two switching valves with valve cores moving down synchronously but with opposite switching states can be selected.

[0044] Existing mop buckets (58) generally include a scraper for drying the mop cloth. The mop bucket provided in this embodiment, which uses air and water for cleaning, also includes a scraper. The scraper's position is simply such that it can dry the mop cloth as the mop (58) is pulled out. The purpose of the functional separation device in the air and water cleaning mop bucket provided in this embodiment is to control the separate operation of cleaning and drying. In actual use, pressing the first button 18 simultaneously closes the first switch valve 21 and opens the second switch valve 22 via the guide post 17. This allows the air pumped in by the first air pump 12 to be discharged through the first switch valve 21, stopping the water spraying device and achieving the function of drying the mop cloth in one step.

[0045] In this embodiment, in order to keep the second cavity 16 dry and facilitate the discharge of wastewater, such as Figure 8 As shown, the mop bucket for air-spraying and water-cleaning also includes a second air pump 44, a first reducer 45, a first spherical plug 46, a second reducer 47, and a second spherical plug 48. A second partition is provided inside the lower bucket 3, dividing the interior of the lower bucket 3 into an independent wastewater chamber 29 and a second cavity 16. A wastewater outlet 59 connected to the wastewater chamber 29 is provided on the lower bucket 3. One end of the first connecting bracket 6 is fixedly connected to the first air pump rod 13 of the first air pump 12, and the other end is fixedly connected to the second air pump rod 49 of the second air pump 44. The first reducer 45 includes... The second reducer 47 includes a first thin tube and a first thick tube that are coaxial and interconnected. The first thick tube is connected to the second air outlet of the second air pump 44. A first spherical plug 46 is disposed inside the first thick tube, and the diameter of the first spherical plug 46 is larger than the diameter of the first thin tube and smaller than the diameter of the first thick tube. The second reducer 47 includes a second thin tube and a second thick tube that are coaxial and interconnected. The second thin tube is connected to the first thick tube. A second spherical plug 48 is disposed inside the second thick tube, and the diameter of the second spherical plug 48 is larger than the diameter of the second thin tube and smaller than the diameter of the first thick tube. The second thick tube is connected to the sewage chamber 29.

[0046] In practical use, the second air pump 44 inflates, pushing the first spherical plug 46 towards the first thin tube until it blocks the end of the first thin tube near the first thick tube. Simultaneously, the air pushes the second spherical plug 48 away from the second thin tube, connecting the second thin tube to the second thick tube. When the second air pump 44 inhales, the first spherical plug 46 moves away from the first thin tube, connecting the first thin tube to the first thick tube, while the second spherical plug 48 moves towards the second thin tube until it blocks the end of the second thin tube near the second thick tube. Throughout the entire process, when the second air pump 44 inhales, the first reducing pipe 45 connects, and the second reducing pipe 47 disconnects, allowing water to flow into the first reducing pipe 45. When the second air pump 44 inflates, the first reducing pipe 45 disconnects, and the second reducing pipe 47 connects, allowing water to flow into the second reducing pipe 47 and then into the sewage chamber 29. As the second air pump 44 operates, the wastewater in the second cavity 16 is continuously drawn into the wastewater chamber 29, keeping the second cavity 16 dry at all times. In existing mop spray washing devices, because the washing chamber cannot be kept consistently dry, the mop cloth becomes damp near the bottom of the washing chamber after several operations during the drying process.

[0047] In this embodiment, to facilitate the disassembly and assembly of the upper bucket 2 and the lower bucket 3, as follows: Figure 1 As shown, the mop bucket for air-spraying and water cleaning includes two spring-loaded structures symmetrically arranged on both sides of the bottom end of the upper bucket 2. Each spring-loaded structure includes a second button 50, a first mounting bracket 51, and a fourth elastic element 52. The first mounting bracket 51 is connected to the bottom end of the upper bucket 2, and the second button 50 is connected to the first mounting bracket 51 via the fourth elastic element 52. Two first slots are symmetrically arranged on both sides of the top end of the lower bucket 3, and one second button 50 is installed in one of the first slots. The fourth elastic element 52 is specifically a spring. In actual use, pressing the second button 50 causes the fourth elastic element 52 to retract, separating the second button 50 from the first slot, thereby separating the upper bucket 2 and the lower bucket 3.

[0048] In this embodiment, as Figure 8As shown, the mop bucket for air-spraying and water cleaning includes a second mounting bracket 53, a third button 54, two fourth buttons 55, two fifth buttons 56, and multiple fifth elastic elements 57. A support frame is fixedly connected to the bucket lid 1 below it. The two fourth buttons 55 and two fifth buttons 56 are symmetrically arranged on opposite sides of the support frame, and each fourth button 55 is fixedly connected to the support frame. The third button 54 is located between the two fifth buttons 56, and both the third button 54 and the two fifth buttons 56 are fixedly connected to the second mounting bracket 53. The second mounting bracket 53 is connected to the support frame via multiple fifth elastic elements 57. The side wall of the upper bucket 2 has corresponding second, third, and fourth slots that match the third button 54, fourth button 55, and fifth button 56, respectively. The fifth elastic elements 57 are specifically springs. In actual use, when the bucket lid 1 needs to be removed, pressing the third button 54 disengages it from the second slot, simultaneously causing the two fifth buttons 56 to disengage from their respective fourth slots, thus separating the bucket lid 1 from the upper bucket 2. With this design, the lid 1 is very easy to install and remove.

[0049] In this embodiment, the water spraying device includes a water spraying plate, and a plurality of water spraying holes 60 are provided along the length of the water spraying plate. The water spraying plate is provided with a water spraying channel that supplies water to each water spraying hole 60. The water spraying channel is connected to the water storage tank 14. In this embodiment, the water spraying plate is specifically located on the lower side of the opening 9, and the water spraying holes 60 are arranged opposite to the mop cloth.

[0050] Finally, it should be noted that the mop bucket provided in this embodiment for air-spraying and water-cleaning is for flat mops.
