One end of the connecting rod is connected to the outer wall of the disinfectant container, and the other end of the connecting rod is connected to the outer wall of the handle.

[0013] Preferably, a long rod is provided inside the rotating port, a valve handle is installed at the top of the outer wall of the long rod, and positioning blocks are provided on both sides of the bottom of the outer wall of the valve handle. By rotating the valve handle, the positioning blocks switch between the first placement groove and the second placement groove. A sealing ring is installed at the bottom of the outer wall of the long rod, and a cylindrical valve is provided at the bottom of the outer wall of the sealing ring. The outer side of the cylindrical valve fits into the inner wall of the circular opening at the bottom of the drainage base.

[0014] Preferably, one end of the water inlet pipe is connected to the water inlet, and the other end of the water inlet pipe is connected to the water pump. The water pump is located at the top of the outer wall of the housing.

[0015] Preferably, the method of use includes the following steps:

[0016] S1. When the disinfectant in the disinfectant tank is used up, the user first lifts the valve handle and removes the positioning block at the bottom of the valve handle from the second placement slot. After rotating, it is inserted into the first placement slot. At this time, the long rod drives the sealing ring and the cylindrical valve to move down. The sealing ring and the cylindrical valve seal the circular opening of the drain base to prevent residual disinfectant from leaking.

[0017] S2. The user rotates the rotating ring counterclockwise. After the triangular block is squeezed, it retracts backward through the telescopic inner rod. The block moves backward to compress the spring. The block gradually moves out of the connecting groove of the outer ring and the slot of the support rod. Then, the user grips the handle to lift the disinfectant canister from the sweeper.

[0018] Preferably, the method of use further includes the following steps:

[0019] S3. Place the disinfectant can filled with disinfectant directly above the outer ring, align the four support rods at the bottom of the can with the connecting holes of the outer ring and slowly insert them until the bottom of the support rods touches the bottom and the bottom of the disinfectant can is in contact with the rubber ring in the second annular groove. Then rotate the rotating ring clockwise. When the user hears a click, stop rotating. At this time, the spring returns to its original position and pushes the locking block through the connecting groove and into the locking slot, fixing the support rod in the connecting hole and completing the installation of the disinfectant can.

[0020] S4. Finally, lift the valve handle and rotate it 90 degrees to insert the positioning block into the second placement slot. The long rod drives the sealing ring and the cylindrical valve to move upward, opening the circular opening. The disinfectant flows into the inner ring and enters the inlet pipe through the inlet. Start the water pump to pump the disinfectant into the first outlet pipe and the second outlet pipe. Then, through the internal pipes of the first and second fixing rods, the disinfectant is delivered to the first spray head and the second spray head. Finally, the disinfectant is sprayed out at high speed from the guide holes of the first spray head and the second spray head, colliding with the air to form a mist. This, combined with the movement of the sweeper, achieves spray disinfection.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention, by installing a rotating ring, a locking block, a spring, a telescopic outer rod, and a telescopic inner rod, enables quick disassembly and installation between the disinfectant tank and the sweeper. By rotating the rotating ring, the locking block extends and retracts under the cooperation of the spring, the telescopic outer rod, and the telescopic inner rod, allowing the locking block to quickly disengage from or engage with the slot, thus quickly completing the disassembly and assembly of the disinfectant tank. This simplifies the disinfectant tank replacement process, reduces the difficulty of operation for users, and significantly shortens the time cost of disinfectant replenishment. It solves the problem that the disassembly and assembly of the disinfectant tank in existing sweepers relies on tools and involves cumbersome steps, resulting in low efficiency in disinfectant replenishment.

[0023] 2. This invention achieves precise positioning and stable fixation of the disinfectant tank during installation by installing a support rod, connecting hole, locking block, and locking groove. The support rod and connecting hole are fitted together to achieve initial positioning of the tank, and the locking groove and locking block further fix the disinfectant tank on the sweeper. The dual cooperation ensures that the tank is installed accurately and firmly, and guarantees that the disinfectant tank will not sway left and right or shift up and down during the operation of the sweeper. This maintains the stability of disinfectant delivery and avoids the impact of tank shaking on the spray disinfection effect. It solves the problems of easy misalignment during installation and easy loosening and shifting during operation of disinfectant tanks in the prior art, which leads to uneven disinfection or equipment failure.

[0024] 3. This invention achieves a seal between the disinfectant tank and the sweeper by installing an outer ring, an inner ring, a second annular groove, and a rubber ring. By embedding the rubber ring in the second annular groove, the rubber ring expands upon contact with water and tightly fills the connection gap, blocking the disinfectant leakage channel. This effectively prevents disinfectant from leaking from the connection point during storage and transportation, reducing disinfectant waste and preventing leaked disinfectant from contaminating the sweeper's body parts, thus extending the equipment's service life. It also solves the problems of inflexible valve opening and closing and poor sealing after closing of existing disinfectant tanks, which lead to residual disinfectant leakage during disassembly and assembly.

[0025] 4. This invention, by installing a valve handle, a first placement slot, a second placement slot, a sealing ring, and a cylindrical valve, achieves precise on / off control and sealing of the disinfectant tank outlet. By rotating the valve handle to switch the position of the positioning block in different placement slots, the cylindrical valve is driven to open and close. Combined with the sealing ring, a tight seal is achieved when the outlet is closed, making valve operation more convenient. Furthermore, when closed, it completely blocks the flow of disinfectant, preventing leakage of residual disinfectant during disassembly and assembly. Simultaneously, it provides a sealed environment for replenishing disinfectant in the tank, solving the problems of inflexible valve operation and inadequate sealing after closure in existing disinfectant tanks, which leads to leakage of residual disinfectant during disassembly and assembly.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Please see Figure 1 , Figure 2 , Figure 5 and Figure 10An embodiment of the present invention provides a sweeper with a spray disinfection function. A drainage base 29 is provided at the bottom of the outer wall of the disinfectant tank 30. A circular opening is provided at the bottom of the outer wall of the drainage base 29. The side of the outer wall of the drainage base 29 is fitted into the side of the inner wall of the inner ring 14. A rotating port 41 is provided at the top of the outer wall of the disinfectant tank 30. A first placement groove 34 and two rectangular blocks 35 are provided on both sides of the rotating port 41. The two first placement grooves 34 are symmetrically distributed on the upper and lower sides of the rotating port 41. The two rectangular blocks 35 are symmetrically distributed on the left and right sides of the rotating port 41. A second placement groove 42 is provided at the top of the outer wall of the rectangular blocks 35. Two connecting rods 31 are provided on the side of the outer wall of the disinfectant tank 30. One end of the connecting rod 31 is connected to the side of the outer wall of the disinfectant tank 30, and the other end of the connecting rod 31 is connected to the side of the outer wall of the handle 32.

[0041] Furthermore, when the user discovers that the disinfectant in the disinfectant canister 30 has run out, they first lift and rotate the valve handle 36 to lift and rotate the positioning block 37 from the second placement slot 42 on the rectangular block 35 to the first placement slot 34. Then, they press the two positioning blocks 37 at the bottom of the outer wall of the valve handle 36 into the first placement slots 34 on the upper and lower sides of the rotating port 41. At this time, the long rod 38 moves downward relative to its position before rotation. The downward movement of the long rod 38 causes the sealing ring 39 to move downward. The sealing ring 39 moves downward at the position directly above the circular opening until it completely fills the circular opening, preventing the residual disinfectant from flowing out during the lifting process. It also provides a sealing base for subsequent disinfection. At this time, the outer wall of the cylindrical valve 40 and the inner wall of the circular opening are in contact with each other.

[0042] Please see Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 An embodiment of the present invention provides a sweeper with a spray disinfection function. The sweeper has a first annular groove 2 at the top of its outer wall of a frustum 1. The inner wall of the first annular groove 2 and the outer wall of an annular block 3 are interlocked. The annular block 3 is located at the bottom of the outer wall of a rotating ring 4. Four grooves 5 are provided on the side of the inner wall of the rotating ring 4. A telescopic outer rod 7 is provided at the bottom of the inner wall of each groove 5. The other end of the telescopic outer rod 7 is nested and connected to a telescopic inner rod 43. The other end of the telescopic inner rod 43 is connected to the inner wall of a telescopic groove 9. At the bottom, the telescopic groove 9 is set at the bottom of the outer wall of the card block 6, the telescopic outer rod 7 is set with a spring 8, the top of the outer wall of the truncated cone 1 is set with an outer ring 10, the outer wall of the outer ring 10 is set with four connecting grooves 11 on the side, the inner wall of the connecting grooves 11 is smooth and spreads outward in an arc shape, the four connecting grooves 11 are evenly distributed on the side of the outer wall of the outer ring 10, and the four connecting holes 12 set at the top of the outer wall of the outer ring 10 are evenly distributed at the top of the outer wall of the outer ring 10, the connecting holes 12 pass through the top of the outer wall of the outer ring 10, and the connecting holes 12 are connected to the connecting grooves 11;

[0043] Furthermore, after the user closes the opening at the bottom of the disinfectant canister 30, the user rotates the rotating ring 4 counterclockwise. At this time, the four locking blocks 6 on the inner wall of the rotating ring 4 and the connecting groove 11 engage with each other. The part of the locking block 6 passing through the connecting groove 11 enters the locking groove 28. When the rotating ring 4 rotates, the locking block 6 has a triangular structure with smooth edges. By rotating counterclockwise, the locking block 6 transmits the pressing force of the edge and the connecting groove 11 to the telescopic inner rod 43. The telescopic inner rod 43 converts the edge pressing force transmitted by the locking block 6 into an axial telescopic force. At this time, the telescopic inner rod 43 extends and retracts backward. The extended and retracted part of the telescopic inner rod 43 enters the interior of the telescopic outer rod 7. The telescopic inner rod 43 extends and retracts backward, driving the locking blocks 6. Moving backward, the locking block 6 moves backward, causing the spring 8 in the telescopic groove 9 to compress towards the groove 5. The inner diameter of the telescopic groove 9 is 20mm larger than the outer diameter of the telescopic outer rod 7, and the inner diameter of the telescopic groove 9 is 10mm larger than the outer diameter of the spring 8. The user continues to rotate the rotating ring 4, and the telescopic inner rod 43 moves backward, causing the telescopic outer rod 7 to enter the telescopic groove 9. At this time, the locking block 6 rotates away from the locking groove 28 and the connecting groove 11. The top of the outer wall of the locking block 6 contacts the side of the outer wall of the outer ring 10, making a rustling sound. At this time, the user stops rotating the rotating ring 4, and the outer wall of the outer ring 10 contacts the locking block 6. The spring 8 transmits the pressure of the compressed spring 8 to the outer wall of the outer ring 10 through the locking block 6.

[0044] At this point, all four locking blocks 6 on the inner wall of the rotating ring 4 are disengaged from the locking slot 28 and the connecting slot 11. The user grips the handle 32 and lifts the disinfectant canister 30. The four support rods 27 of the disinfectant canister 30 move upward along the connecting hole 12 in the outer ring 10 until the support rods 27 are completely disengaged from the connecting hole 12. Then the user opens the canister lid 33 and puts the disinfectant into the disinfectant canister 30 for filling.

[0045] Please see Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 An embodiment of the present invention provides a sweeper with a spray disinfection function. The top of the outer wall of the truncated cone 1 is provided with an inner ring 14. A second annular groove 13 is formed between the inner wall of the outer ring 10 and the outer wall of the inner ring 14. A rubber ring 26 is provided in the second annular groove 13. A water inlet 15 is provided on the side of the inner wall of the inner ring 14. The water inlet 15 is connected to a water inlet pipe 16. The truncated cone 1 is provided at the top of the outer wall of the outer shell 24. Four wheels 25 are provided at the bottom of the outer wall of the outer shell 24. Two connecting rods 31 are provided on the side of the outer wall of the disinfectant tank 30. One end of the connecting rod 31 is connected to the side of the outer wall of the disinfectant tank 30, and the other end of the connecting rod 31 is connected to the side of the outer wall of the handle 32.

[0046] Furthermore, after the disinfectant is filled, the user places the disinfectant canister 30 directly above the outer ring 10 using the handle 32. Then, the user aligns the four support rods 27 at the bottom of the outer wall of the disinfectant canister 30 with the four connecting holes 12 at the top of the outer wall of the outer ring 10, and slowly inserts the support rods 27 into the connecting holes 12 until the bottom of the outer wall of the support rods 27 contacts the bottom of the inner wall of the connecting hole 12. At this point, the disinfectant canister 30, through the interlocking action of the support rods 27 and the connecting holes 12, prevents itself from swaying left and right, ensuring the disinfectant canister 30 remains stable during the operation of the sweeper. The stability of the disinfectant tank 30 is ensured by contact between the bottom of the outer wall and the rubber ring 26. The rubber ring 26 expands when it comes into contact with water. The rubber ring 26 is made of natural rubber as the basic material and contains hydrophilic polymer expansion components, namely polyacrylamide and sodium carboxymethyl cellulose. The hydrophilic polymer material will swell when it comes into contact with water. The molecular chains combine with water molecules through hydrogen bonds, absorb water and stretch, causing the rubber ring 26 to expand in volume. At the same time, the elastic skeleton of the rubber substrate will limit excessive expansion, ensuring that the expansion tightly fills the joint gap and achieves a seal and water stop.

[0047] At this point, the slot 28 on the outer side of the support rod 27 aligns with the connecting slot 11 in the outer ring 10. Then, the user releases the handle 32 and rotates the rotating ring 4 clockwise. The rotation of the rotating ring 4 causes the telescopic outer rod 7 in the groove 5 to rotate. The telescopic outer rod 7 causes the telescopic inner rod 43 to rotate. The telescopic inner rod 43 causes the locking block 6 to rotate. When the locking block 6 rotates to the connecting slot 11 on the outer side of the outer ring 10, the elastic force of the spring 8 on the locking block 6 is no longer blocked by the outer side of the outer ring 10. The locking block 6 is popped forward and inserted into the locking slot 28. At the same time, the locking block 6 moves forward, causing the telescopic inner rod 43 to extend from the inside of the telescopic outer rod 7. The locking block 6 makes a clicking sound when it contacts the locking slot 28. After hearing the clicking sound, the user stops rotating the rotating ring 4. The locking block 6 enters the locking slot 28 through the connecting slot 11. At this time, the locking block 6 fixes the support rod 27 in the connecting hole 12, so that the disinfectant tank 30 will not shake up and down during the operation of the sweeper, thus ensuring the stability of the spray disinfection.

[0048] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 9An embodiment of the present invention provides a sweeper with a spray disinfection function. The bottom of the outer wall of the disinfectant tank 30 is provided with a drainage base 29. The bottom of the outer wall of the drainage base 29 is provided with a circular opening. The side of the outer wall of the drainage base 29 is fitted with the side of the inner wall of the inner ring 14. The top of the outer wall of the disinfectant tank 30 is provided with a rotating port 41. Two first placement slots 34 and two rectangular blocks 35 are provided on both sides of the rotating port 41. The two first placement slots 34 are symmetrically distributed on both sides of the rotating port 41. The two rectangular blocks 35 are symmetrically distributed on both sides of the rotating port 41. The top of the outer wall of the rectangular block 35 is provided with a second placement slot 42.

[0049] Furthermore, after the disinfectant tank 30 is fixed, the outer side of the drain base 29 and the inner side of the inner ring 14 are in contact with each other, and the bottom of the outer wall of the drain base 29 is 50mm away from the bottom of the inner wall of the inner ring 14, so that the disinfectant can be discharged from the disinfectant tank 30. Then the user lifts the valve handle 36 and rotates the valve handle 36 90 degrees, so that the positioning block 37 placed in the first placement slot 34 is rotated to the top of the second placement slot 42. Then the two positioning blocks 37 at the bottom of the valve handle 36 are pressed into the second placement slot 42.

[0050] At the same time, when the valve handle 36 is lifted, the long rod 38 is also lifted. The long rod 38 moves upward, causing the sealing ring 39 and the cylindrical valve 40 to move upward, thereby opening the circular opening in the drain base 29 and releasing the disinfectant from the disinfectant tank 30. The disinfectant flows into the annular cavity of the inner ring 14. The inner wall of the inner ring 14 is provided with an inlet 15, and the disinfectant flows from the annular cavity of the inner ring 14 into the inlet 15.

[0051] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a sweeper with a spray disinfection function. One end of the water inlet pipe 16 is connected to the water inlet 15, and the other end of the water inlet pipe 16 is connected to the water pump 17. The water pump 17 is located at the top of the outer wall of the outer shell 24. The two sides of the outer wall of the water pump 17 are connected to the first water outlet pipe 18 and the second water outlet pipe 19. The other end of the first water outlet pipe 18 is connected to the first fixed rod 20. The first water outlet pipe 18 passes through the interior of the first fixed rod 20 and is connected to the first spray head 21 on the side of the outer wall of the first fixed rod 20. The other end of the second water outlet pipe 19 is connected to the second fixed rod 22. The second water outlet pipe 19 passes through the interior space of the second fixed rod 22 and is connected to the second spray head 23 on the side of the outer wall of the second fixed rod 22.

[0052] Furthermore, after opening the valve, the user starts the sweeper and water pump 17. The sweeper moves and sweeps via wheels 25, while the water pump 17 starts. Disinfectant enters the inlet pipe 16 from the inlet 15. Under the action of the water pump 17, the disinfectant in the inlet pipe 16 is drawn in by negative pressure and then pumped into the first outlet pipe 18 and the second outlet pipe 19. The first outlet pipe 18 is connected to the first spray head 21 through the inside of the first fixing rod 20, and the second outlet pipe 19 is connected to the second spray head 23 through the inside of the second fixing rod 22. The outer wall surface of the first and second spray heads 23 is provided with tiny guide holes. The high pressure of the water pump 17 pumps the disinfectant from the first outlet pipe 18 and the second outlet pipe 19 into the guide holes of the first spray head 21 and the second spray head 23. The disinfectant is compressed and accelerated in the guide holes to form a high-speed jet. After the high-speed jet is sprayed out from the first spray head 21, it will violently collide with the surrounding still air. The air generates reverse resistance to the high-speed disinfectant. At the same time, turbulence occurs inside the disinfectant due to the speed difference. Under the combined action of the two forces, the disinfectant is torn into a large number of tiny droplets, which eventually form a mist.

[0053] Working principle: When the disinfectant in the disinfectant tank 30 is exhausted, first lift the valve handle 36 and take out the positioning block 37 at the bottom of the valve handle 36 from the second placement groove 42. After rotating, it will be inserted into the first placement groove 34. At this time, the long rod 38 will drive the sealing ring 39 and the cylindrical valve 40 to move down. The sealing ring 39 and the cylindrical valve 40 will prevent residual disinfectant from leaking through the circular opening of the sealing drain base 29. Then, the user will rotate the rotating ring 4 counterclockwise. The triangular locking block 6 will be squeezed and retracted backward. The backward-moving locking block 6 will compress the spring 8. At this time, the locking block 6 will gradually move out of the connecting groove 11 of the outer ring 10 and the locking groove 28 of the support rod 27. Then, hold the handle 32 to lift the disinfectant tank 30 from the sweeper.

[0054] After filling the disinfectant canister 30 with disinfectant, place the disinfectant canister 30 directly above the outer ring 10, align the four support rods 27 at the bottom of the canister with the connecting holes 12 of the outer ring 10 and slowly insert them until the bottom of the support rods 27 touches the bottom and the bottom of the disinfectant canister 30 is in contact with the rubber ring 26 in the second annular groove 13. Then rotate the rotating ring 4 clockwise. When the user hears a click, stop rotating. At this time, the spring 8 returns to its original position and pushes the locking block 6 through the connecting groove 11 and into the locking groove 28, fixing the support rods 27 in the connecting hole 12, thus completing the installation of the disinfectant canister 30.

[0055] Finally, lift the valve handle 36 and rotate it 90 degrees to insert the positioning block 37 into the second placement slot 42. The long rod 38 drives the sealing ring 39 and the cylindrical valve 40 to move upward, opening the circular opening. The disinfectant flows into the inner ring 14 and enters the inlet pipe 16 through the inlet 15. After the water pump 17 is started, the disinfectant is sucked in by negative pressure and pumped into the first outlet pipe 18 and the second outlet pipe 19 by the water pump 17. Then, through the internal pipes of the first fixed rod 20 and the second fixed rod 22, the disinfectant is delivered to the first spray head 21 and the second spray head 23. Finally, it is sprayed out at high speed from the guide holes of the first spray head 21 and the second spray head 23, colliding with the air to form a mist. The spray disinfection is achieved in conjunction with the movement of the sweeper.
