Description

Technical Field

[0001] This invention relates to the field of disinfection technology, specifically to a long-lasting disinfection device for logistics vehicles. Background Technology

[0002] With the increasing prevalence of online shopping, goods are often shipped via express delivery boxes. However, these boxes can easily harbor viruses, which can spread through human contact. To control this spread, disinfection spraying is necessary on delivery vehicles. As technology advances, long-lasting disinfectants are now available on the market, requiring disinfection equipment for application. In practice, different concentrations of disinfectant are often used depending on the environment. However, most existing disinfection equipment only has spraying capabilities and lacks mixing functions. This necessitates carrying large quantities of different concentrations of disinfectant, which is time-consuming, labor-intensive, and requires manual mixing by staff on-site. However, this often results in concentrations that are too low or too high, making the equipment impractical. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a long-lasting disinfection device that solves the problem that most traditional disinfection devices only have a spraying function and lack a mixing function. When disinfecting in different environments, staff need to manually mix the disinfectant on-site, which easily leads to the disinfectant concentration being too low or too high, resulting in poor practicality. This device can automatically mix the disinfectant based on the amount of water added, saving time and effort, reducing labor intensity, and effectively reducing the occurrence of disinfectant concentrations that are too low or too high due to manual mixing. It can also be used in multiple locations, making it widely applicable.

[0004] This invention is achieved using the following technical solution:

[0005] A long-lasting disinfection device includes a base, on which a high-concentration storage tank, a mixing tank, and an atomizing nozzle are fixed. A proportioning cylinder is mounted on the top of the mixing tank. An inlet pipe connects the proportioning cylinder and the high-concentration storage tank. An outlet pipe is installed at the bottom of the proportioning cylinder and at the top of the mixing tank. One-way valves are fixed on both the inlet and outlet pipes. A matching proportioning piston is slidably mounted inside the proportioning cylinder. An extension rod is mounted on the top of the proportioning piston, with its tip extending outside the proportioning cylinder and connected to a connecting crossbar. A control screw is rotatably mounted on the top of the mixing tank. A control screw is threaded onto the end of the mixing chamber. The top of the control screw is mounted on the bottom of the connecting crossbar. A servo motor is mounted on the top of the mixing chamber via an L-shaped mounting plate. A vertical screw is mounted on the output end of the servo motor. The bottom end of the vertical screw extends into the mixing chamber. A vertical moving block is threaded onto the vertical screw. A liquid depth detector is mounted on the side of the vertical moving block. A limiting guide unit is mounted on the liquid depth detector. An adapter transmission mechanism for driving the control screw to rotate simultaneously is mounted on the vertical screw. A uniform spraying mechanism for making the atomizing nozzle swing back and forth during movement is mounted on the device base.

[0006] With the above structure, when the servo motor is started, the vertical screw and vertical moving block drive the liquid depth detector to move up and down, detecting the amount of water in the mixing tank. At the same time, the rotation of the vertical screw also drives the proportioning piston to slide up and down in the proportioning cylinder through the adapter transmission mechanism, control screw, control cylinder, connecting crossbar and extension moving rod. At this time, with the cooperation of the inlet pipe, outlet pipe and one-way valve, the appropriate amount of high-concentration disinfectant in the high-concentration storage tank can be drawn into the mixing tank, thus realizing the purpose of automatic proportioning according to the amount of water added. It saves time and effort, reduces labor intensity, and can effectively reduce the situation of disinfectant concentration being too low or too high due to manual proportioning. It has good practicality.

[0007] Preferably, the adaptive transmission mechanism includes a transmission worm gear sleeved on a vertical screw, a mounting bearing mounted on the top of the mixing box via a straight rod, a hollow sleeve sleeved inside the mounting bearing, a transmission worm wheel meshing with the transmission worm gear sleeved on the hollow sleeve, a telescopic indicator rod slidably mounted inside the hollow sleeve, a driving wheel mounted at the end of the telescopic indicator rod, a driven wheel sleeved on the control screw, the bottom of the outer circle of the driving wheel fitting against the top of the driven wheel, and an adjustment component mounted on the telescopic indicator rod.

[0008] Preferably, the adjustment assembly includes an adjustment screw rotatably mounted on the inner wall of the hollow sleeve, a telescopic rod threaded onto the adjustment screw, one end of the adjustment screw extending outside the hollow sleeve and fitted with a hexagonal connecting rod, an anti-disengagement block fitted at the end of the hexagonal connecting rod, an adjustment knob slidably fitted onto the hexagonal connecting rod, and an anti-rotation unit fitted onto the adjustment knob.

[0009] By adjusting the component settings, when the adjustment knob is turned, the active rotating wheel will move left and right through the hexagonal connecting rod, adjusting screw and telescopic rod, changing the transmission ratio between it and the driven rotating wheel, thus realizing the purpose of automatically mixing disinfectant solutions of different concentrations and improving the applicability of the device.

[0010] Preferably, the anti-rotation unit includes multiple fixing rods evenly installed on the side of the adjustment knob, multiple fixing holes evenly opened at the end of the hollow sleeve, the ends of the fixing rods extending into the fixing holes, and an elastic reset element installed on the adjustment knob.

[0011] Preferably, the elastic reset element includes a reset spring sleeved on the hexagonal connecting rod, with both ends of the reset spring respectively abutting the anti-disengagement block and the side of the adjustment knob.

[0012] Preferably, the limiting guide unit includes a limiting guide rod installed on the inner wall of the bottom of the mixing tank, a limiting slider slidably sleeved on the limiting guide rod, and the limiting slider is installed on the side of the liquid depth detector.

[0013] Preferably, the uniform spraying mechanism includes a connecting rod rotatably mounted on the top of the device base, a rectangular support rod mounted on the top of the connecting rod, a movable moving rod slidably sleeved on the rectangular support rod, an atomizing nozzle mounted on the top of the movable moving rod, four fixed protrusions evenly mounted on the bottom of the device base, each of the four fixed protrusions having a rotating hole on its side, a traveling shaft rotatably mounted in every two corresponding rotating holes, and locking traveling wheels mounted at both ends of the two traveling shafts, one of the traveling shafts being connected to a swing assembly for driving the connecting rod to reciprocate, and a fastening unit mounted on the movable moving rod.

[0014] With the uniform spraying mechanism in place, when the device is moved, the locking wheels and the rotating shaft will rotate, which in turn will drive the connecting rod to rotate back and forth through the swing assembly. This allows the atomizing nozzle to swing back and forth while moving, resulting in a better spraying effect.

[0015] Preferably, the fastening unit includes a fastening bolt disposed on the movable moving rod, the movable moving rod having a fastening screw hole on its side, the fastening bolt being threaded into the fastening screw hole, and one end of the fastening bolt being in contact with the side of the rectangular support rod.

[0016] Preferably, the swing assembly includes a reciprocating swing arm sleeved and mounted on a connecting rotating rod. The top of the device base has a mounting hole, and a drive shaft is rotatably mounted in the mounting hole. A drive disc is mounted on the top of the drive shaft, and an eccentric rotating column is eccentrically mounted on the top of the drive disc. A strip groove is provided on the top of the reciprocating swing arm, and the eccentric rotating column is adapted to slide in the strip groove. The drive shaft is connected to the travel shaft through a gear transmission unit.

[0017] Preferably, the gear transmission unit includes a first bevel gear sleeved on the travel shaft, and a second bevel gear meshing with the first bevel gear is installed at the bottom end of the drive shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention has a reasonable structure. When disinfection is required on a logistics vehicle, the device can be placed on the vehicle and then pushed back and forth to disinfect it. After disinfection, the locking wheels can be locked. Simultaneously, before disinfection, the servo motor can be activated, which will drive the liquid depth detector up and down via the vertical screw and vertical moving block to detect the amount of water added. At the same time, the rotation of the vertical screw will also drive the control screw to rotate simultaneously via the transmission worm, transmission worm wheel, hollow sleeve, telescopic marker, driving wheel, and driven wheel. This allows the control screw to rotate via the control cylinder and connecting... The connecting rod and extension rod drive the proportioning piston to slide up and down inside the proportioning cylinder. With the cooperation of the inlet pipe, outlet pipe and one-way valve, an appropriate amount of high-concentration disinfectant solution in the high-concentration storage tank can be drawn into the mixing tank. This achieves the purpose of automatic proportioning according to the amount of water added, saving time and effort, reducing labor intensity, and effectively reducing the occurrence of disinfectant concentrations that are too low or too high due to manual proportioning. It can also be used in many places, such as shopping malls and supermarkets. When using it, you only need to push the device to carry out disinfection, making it widely applicable.

[0020] 2. In this invention, when the adjustment knob is pulled and rotated, the telescopic indicator rod will move left and right through the hexagonal connecting rod and the adjusting screw. The movement of the telescopic indicator rod will drive the active rotating wheel to move, thereby changing the transmission ratio between the active rotating wheel and the driven rotating wheel. This will cause the movement distance of the proportioning piston to change when the liquid depth detector moves the same distance, thus achieving the purpose of automatically proportioning disinfectant solutions of different concentrations and improving the applicability of the device.

[0021] 3. In this invention, when the adjustment knob is released, the spring force of the return spring will squeeze and push the adjustment knob to automatically reset, thereby allowing the fixing rod to automatically insert into the fixing hole, fixing the adjustment knob and keeping it in a fixed state. This effectively reduces the situation where the proportion of the device changes due to the rotation of the adjustment knob, resulting in good stability during use.

[0022] 4. In this invention, when the pushing device moves, the locking walking wheel and the walking shaft will rotate. The rotation of the walking shaft will drive the eccentric rotating column to rotate circumferentially through the first bevel gear, the second bevel gear, the driving shaft and the driving disc. The eccentric rotating column will drive the connecting rotating rod to rotate back and forth through the reciprocating swing rod. In turn, the atomizing nozzle will swing back and forth through the rectangular support rod and the movable moving rod, thereby achieving the purpose of making the atomizing nozzle swing back and forth while moving, resulting in a better spraying effect.

[0023] 5. In this invention, by setting up a rectangular support rod, a movable moving rod, and a fastening bolt, the movable moving rod will be fixed or loosened when the fastening bolt is rotated. Then, the height of the atomizing nozzle can be adjusted by sliding the movable moving rod up and down, thereby achieving the purpose of adjusting the spraying height of the device, which has a wide range of applications.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In the description of this invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements present. Conversely, when an element is referred to as being "directly" connected to another element, there are no intermediate elements.

[0036] Please see Figures 1-8This is a preferred embodiment of the long-lasting disinfection device of the present invention, used to disinfect logistics vehicles to achieve the purpose of long-lasting disinfection. Specifically, the long-lasting disinfection device includes a base 1, on which a high-concentration storage tank 2, a mixing tank 3, and an atomizing nozzle 4 are fixed. The atomizing nozzle 4 is connected to the mixing tank 3 via a pump. A proportioning cylinder 5 is installed on the top of the mixing tank 3. The proportioning cylinder 5 and the high-concentration storage tank 2 are connected by an inlet pipe. An outlet pipe is installed on the bottom of the proportioning cylinder 5 and the top of the mixing tank 3. It should be noted that the high-concentration storage tank 2, the inlet pipe, the proportioning cylinder 5, the outlet pipe, and the mixing tank 3 are sequentially connected. A one-way valve is fixed on both the inlet pipe and the outlet pipe. A matching proportioning piston 6 is slidably installed inside the proportioning cylinder 5. An extension rod 7 is installed on the top of the proportioning piston 6. The top of the extension rod 7 extends outside the proportioning cylinder 5 and is connected to a connecting crossbar 10. A control screw 8 is rotatably installed on the top of the mixing tank 3. The control screw 8 can be connected to the mixing tank 3 via a bearing. The top of the mixing tank 3 is rotatably connected; the top of the control screw 8 is threaded with a control screw cylinder 9, the top of the control screw cylinder 9 is installed on the bottom of the connecting crossbar 10, the top of the mixing tank 3 is mounted with a servo motor 11 via an L-shaped mounting plate, the output end of the servo motor 11 is mounted with a vertical screw 12, the bottom end of the vertical screw 12 extends into the mixing tank 3, a vertical moving block 13 is threaded on the vertical screw 12, a liquid depth detector 14 is mounted on the side of the vertical moving block 13, the liquid depth detector 14 is located inside the mixing tank 3, and during detection, it moves from bottom to top for detection; a limiting guide unit is mounted on the liquid depth detector 14, an adapter transmission mechanism for driving the control screw 8 to rotate simultaneously is mounted on the vertical screw 12, and a uniform spraying mechanism for making the atomizing nozzle 4 swing back and forth during movement is mounted on the device base 1.

[0037] With the above structure, when the servo motor 11 is started, it drives the vertical screw 12 to rotate, which in turn drives the liquid depth detector 14 to move up and down through the vertical moving block 13, thus detecting the amount of water put into the mixing tank 3. At the same time, the rotation of the vertical screw 12 also drives the control screw 8 to rotate through the adapter transmission mechanism. The rotation of the control screw 8 drives the proportioning piston 6 to slide up and down in the proportioning cylinder 5 through the control cylinder 9, the connecting crossbar 10 and the extension moving rod 7. At this time, with the cooperation of the inlet pipe, the outlet pipe and the one-way valve, the high-concentration disinfectant in the high-concentration storage tank 2 can be drawn into the mixing tank 3, thus realizing the purpose of automatic proportioning according to the amount of water put in. It saves time and effort, reduces labor intensity, and can effectively reduce the situation of the disinfectant concentration being too low or too high due to manual proportioning. It has good practicality and can be used in many places, such as shopping malls and supermarkets. When using it, you only need to push the device to carry out disinfection, and its application range is wide.

[0038] like Figure 3As shown, in a preferred embodiment of this invention, the adaptive transmission mechanism includes a transmission worm gear 15 sleeved on a vertical screw 12. A mounting bearing 16 is mounted on the top of the mixing box 3 via a straight rod. A hollow sleeve 17 is sleeved inside the mounting bearing 16. A transmission worm wheel 21, meshing with the transmission worm gear 15, is sleeved on the hollow sleeve 17. A telescopic marker 18 is slidably mounted inside the hollow sleeve 17. It should be noted that the telescopic marker 18 can only slide left and right within the hollow sleeve 17 and will not rotate. A driving wheel 19 is mounted at the end of the telescopic marker 18. A driven wheel 20 is sleeved on the control screw 8. The bottom of the outer circle of the driving wheel 19 is in contact with the top of the driven wheel 20. It should be noted that both the driving wheel 19 and the driven wheel 20 are friction wheels. When the driving wheel 19 rotates, it will drive the driven wheel 20 to rotate as well. An adjustment component is mounted on the telescopic marker 18. The advantage of this setup is that when the vertical screw 12 rotates, it will drive the transmission worm gear 15 to rotate. The rotation of the transmission worm gear 15 will drive the hollow sleeve 17 to rotate through the transmission worm wheel 21. The rotation of the hollow sleeve 17 will drive the driving wheel 19 to rotate through the telescopic marker 18. The rotation of the driving wheel 19 will drive the driven wheel 20 to rotate, thus achieving the purpose of driving the control screw 8 to rotate simultaneously.

[0039] For example Figure 5 As shown, in this embodiment, the adjustment assembly includes an adjusting screw 22 rotatably mounted on the inner wall of the hollow sleeve 17. The adjusting screw 22 can only rotate and will not move. A telescopic rod 18 is threaded onto the adjusting screw 22. One end of the adjusting screw 22 extends outside the hollow sleeve 17 and is fitted with a hexagonal connecting rod 23. An anti-detachment block 24 is installed at the end of the hexagonal connecting rod 23. An adjusting knob 25 is slidably fitted onto the hexagonal connecting rod 23. It should be noted that the adjusting knob 25 can only slide left and right on the hexagonal connecting rod 23, and when the adjusting knob 25 rotates, it will drive the hexagonal connecting rod 23 to rotate together. An anti-rotation unit is installed on the adjusting knob 25. The advantage of this setup is that when the adjustment knob 25 is turned, the telescopic pointer 18 will move left and right through the hexagonal connecting rod 23 and the adjusting screw 22. The movement of the telescopic pointer 18 will drive the active rotating wheel 19 to move, which will change the transmission ratio between the active rotating wheel 19 and the driven rotating wheel 20. This will cause the moving distance of the proportioning piston 6 to change when the liquid depth detector 14 moves the same distance, thereby achieving the purpose of automatic proportioning of disinfectant solutions of different concentrations and improving the applicability of the device.

[0040] For example Figure 6As shown, in this embodiment, the anti-rotation unit includes multiple fixing rods 26 evenly installed on the side of the adjustment knob 25. Multiple fixing holes 27 are evenly provided at the end of the hollow sleeve 17. The ends of the fixing rods 26 extend into the fixing holes 27. An elastic reset element is installed on the adjustment knob 25. The advantage of this design is that when the adjustment knob 25 is moved, the positional relationship between the fixing rods 26 and the fixing holes 27 changes, thereby fixing or loosening the adjustment knob 25. This effectively reduces the possibility of changes in the device's proportions due to the adjustment knob 25 rotating, resulting in good stability during use.

[0041] For example Figure 6 As shown, in this embodiment, the elastic reset element includes a reset spring 28 sleeved on the hexagonal connecting rod 23. The two ends of the reset spring 28 are respectively attached to the anti-detachment block 24 and the side of the adjusting knob 25. It should be noted that the reset spring 28 is in a compressed state. The advantage of this design is that when the adjusting knob 25 is released, the elastic force of the reset spring 28 will compress and push the adjusting knob 25 to automatically reset, thereby allowing the fixing rod 26 to automatically insert into the fixing hole 27, fixing the adjusting knob 25 and maintaining it in a stable and reliable fixed state.

[0042] For example Figure 4 As shown, in a preferred embodiment of this invention, the limiting guide unit includes a limiting guide rod 29 installed on the inner wall of the bottom of the mixing tank 3. The limiting guide rod 29 and the vertical screw 12 are aligned in the same length direction. A limiting slider 30 is slidably sleeved on the limiting guide rod 29, and the limiting slider 30 is installed on the side of the liquid depth detector 14. The advantage of this arrangement is that the liquid depth detector 14 can only move vertically up and down, and will not rotate with the vertical screw 12, thus achieving a limiting guide function.

[0043] For example Figure 7 and Figure 8As shown, in a preferred embodiment of this invention, the uniform spraying mechanism includes a connecting rod 34 rotatably mounted on the top of the device base 1. The connecting rod 34 can be rotatably connected via bearings. A rectangular support rod 35 is mounted on the top of the connecting rod 34, and a movable moving rod 36 is slidably sleeved on the rectangular support rod 35. It should be noted that the movable moving rod 36 can only slide up and down. The atomizing nozzle 4 is mounted on the top of the movable moving rod 36. Four fixed protrusions 31 are evenly mounted on the bottom of the device base 1. Rotation holes are opened on the sides of the four fixed protrusions 31. A traveling shaft 32 is rotatably mounted in every two corresponding rotation holes. Locking traveling wheels 33 are mounted on both ends of the two traveling shafts 32. A swing assembly for driving the connecting rod 34 to reciprocate is connected to one of the traveling shafts 32. A fastening unit is mounted on the movable moving rod 36. The advantage of this design is that when the pushing device moves, the locking travel wheel 33 and the travel shaft 32 will rotate. The rotation of the travel shaft 32 will drive the connecting rod 34 to rotate back and forth through the swing assembly. In turn, the atomizing nozzle 4 can be driven to swing back and forth through the rectangular support rod 35 and the movable moving rod 36, thereby achieving the purpose of allowing the atomizing nozzle 4 to swing back and forth while moving, resulting in a better spraying effect.

[0044] For example Figure 7 As shown, in this embodiment, the fastening unit includes a fastening bolt 43 disposed on the movable moving rod 36. A fastening screw hole is provided on the side of the movable moving rod 36, and the fastening bolt 43 is threaded into the fastening screw hole. One end of the fastening bolt 43 is in contact with the side of the rectangular support rod 35. The advantage of this arrangement is that when the fastening bolt 43 is rotated, it moves under the action of the fastening screw hole, thereby fixing or loosening the movable moving rod 36, thus achieving the purpose of adjusting the height of the atomizing nozzle 4, and has a wide range of applications.

[0045] For example Figure 8 As shown, in this embodiment, the swing assembly includes a reciprocating swing rod 40 sleeved and mounted on the connecting rotating rod 34. The top of the device base 1 has a mounting hole, within which a drive shaft 37 is rotatably mounted. The drive shaft 37 can only rotate and will not move. A drive disc 38 is mounted on the top of the drive shaft 37, and an eccentric rotating column 39 is eccentrically mounted on the top of the drive disc 38. A strip-shaped groove is provided on the top of the reciprocating swing rod 40, and the eccentric rotating column 39 is slidably mounted within the strip-shaped groove. The drive shaft 37 is connected to the traveling shaft 32 via a gear transmission unit. The advantage of this configuration is that when the drive shaft 37 rotates, it drives the eccentric rotating column 39 to rotate circumferentially via the drive disc 38. The eccentric rotating column 39's circumferential rotation causes the reciprocating swing rod 40 to swing back and forth around the connecting rotating rod 34, thus achieving the purpose of driving the connecting rotating rod 34 to rotate back and forth.

[0046] For example Figure 8 As shown, in this embodiment, the gear transmission unit includes a first bevel gear 41 sleeved and mounted on the travel shaft 32, and a second bevel gear 42 meshing with the first bevel gear 41 is mounted on the bottom end of the drive shaft 37. The advantage of this arrangement is that when the travel shaft 32 rotates, it will drive the first bevel gear 41 to rotate, which in turn will drive the second bevel gear 42 and the drive shaft 37 to rotate synchronously, thus achieving the purpose of transmission.

[0047] Working principle of this invention:

[0048] When disinfection is required on a logistics vehicle, the device can be placed on the vehicle and pushed back and forth to disinfect it. After disinfection, the locking wheels 33 can be locked. Before disinfection, an appropriate amount of water can be added to the mixing tank 3. The servo motor 11 is then started. The servo motor 11 drives the vertical screw 12 to rotate. Under the action of the limiting guide rod 29 and the limiting slider 30, the rotation of the vertical screw 12 drives the liquid depth detector 14 to move upwards via the vertical moving block 13. Simultaneously, the rotation of the vertical screw 12 also drives the hollow sleeve 17 to rotate via the transmission worm gear 15 and the transmission worm wheel 21. The rotation of the hollow sleeve 17 drives the active rotating wheel 19 to rotate via the telescopic marker 18. The active rotating wheel 19 drives the driven rotating wheel 20 to rotate, which in turn drives the control screw 8 to rotate simultaneously. The rotation of the control screw 8 drives the control screw cylinder 9, the connecting crossbar 10, and... The extension rod 7 drives the proportioning piston 6 to slide downwards inside the proportioning cylinder 5. With the cooperation of the inlet pipe, outlet pipe, and one-way valve, the high-concentration disinfectant in the proportioning cylinder 5 can be put into the mixing tank 3. When the liquid depth detector 14 moves upwards until it is just separated from the water surface, the servo motor 11 is started in reverse. At this time, the liquid depth detector 14 will move downwards, and the proportioning piston 6 will move upwards, which can draw the high-concentration disinfectant in the high-concentration storage tank 2 into the proportioning cylinder 5, so that the proportioning can be continued next time. This achieves the purpose of automatic proportioning according to the amount of water added, saving time and effort, reducing labor intensity, and effectively reducing the situation of the disinfectant concentration being too low or too high due to manual proportioning. It is practical and can be used in many places, such as shopping malls and supermarkets. When using it, you only need to push the device to carry out disinfection. It has a wide range of applications.

[0049] When the adjustment knob 25 is pulled, the fixed insertion rod 26 will move out of the fixed insertion hole 27 and be released. At this time, the adjustment knob 25 can be rotated. The rotation of the adjustment knob 25 will drive the telescopic indicator 18 to move left and right through the hexagonal connecting rod 23 and the adjustment screw 22. The movement of the telescopic indicator 18 will drive the active rotating wheel 19 to move, which will change the transmission ratio between the active rotating wheel 19 and the driven rotating wheel 20. This will change the movement distance of the proportioning piston 6 when the liquid depth detector 14 moves the same distance, thereby realizing the purpose of automatic proportioning of disinfectant solutions of different concentrations and improving the applicability of the device.

[0050] After adjustment, release the adjustment knob 25. Under the elastic force of the return spring 28, the adjustment knob 25 will be squeezed and pushed to automatically reset, thereby allowing the fixing rod 26 to automatically insert into the fixing hole 27, fixing the adjustment knob 25 and keeping it in a fixed state. This effectively reduces the situation where the ratio of the device changes due to the rotation of the adjustment knob 25, resulting in good stability during use.

[0051] When the pushing device moves, the locked traveling wheel 33 and the traveling shaft 32 will rotate. The rotation of the traveling shaft 32 will drive the drive shaft 37 to rotate synchronously through the first bevel gear 41 and the second bevel gear 42. The rotation of the drive shaft 37 will drive the eccentric rotating column 39 to rotate circumferentially through the drive disc 38. The eccentric rotating column 39 will drive the connecting rotating rod 34 to rotate back and forth through the reciprocating swing rod 40. In turn, the atomizing nozzle 4 will swing back and forth through the rectangular support rod 35 and the movable moving rod 36, thereby achieving the purpose of making the atomizing nozzle 4 swing back and forth while moving, resulting in a better spraying effect.
