Description

Technical Field

[0001] This invention relates to a disinfection device, specifically a hand disinfection device and its disinfection method, belonging to the field of sanitary equipment technology. Background Technology

[0002] With increased awareness of safety and hygiene, disinfecting hands and other body parts is extremely common in daily production and life. Furthermore, various disinfection devices have been developed to facilitate disinfection and ensure public health.

[0003] Hand sanitizers are common disinfection devices that use physical or chemical disinfecting elements to act on toxic substances to achieve disinfection. They are widely used in medical and daily life applications and are commonly found in large public places such as squares, schools, factories, subway stations, shopping malls, stadiums, and concert venues.

[0004] During the use of hand sanitizers, the machine typically sprays a stream of water mixed with disinfectant onto the user's hands. This method cannot completely rinse the user's hands, leaving some disinfectant residue on their hands, requiring the user to wash their hands elsewhere. Furthermore, it can only clean and disinfect the hands, but cannot dry them. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hand disinfection device, comprising a housing, a handwashing chamber on the front side of the housing, an atomizing nozzle and a gas nozzle respectively disposed on the top two sides of the handwashing chamber, a sensor and an auxiliary sensor respectively disposed on the front side of the atomizing nozzle and the gas nozzle, a water pump disposed on one side of the top of the atomizing nozzle, a heating bend fixedly connected to one end of the water pump, a liquid three-way valve fixedly connected to the bottom of the heating bend, a heating wire and a gas guide box sleeved on the outside of the heating bend, a spiral blade fixedly connected inside the gas guide box, the gas entering the gas guide box is guided by the spiral blade, causing the gas to move along a spiral downward path, increasing the time for heat exchange between the gas and the liquid inside the sealed space, the gas guide box... A vertical air duct is provided on one side, and a three-way gas valve is fixedly connected to the top of the vertical air duct. An air pump is installed between the top of the three-way gas valve and the gas nozzle. A one-way valve is fixedly connected to one side of the vertical air duct, and a storage tank is installed on one side of the three-way gas valve. An installation bend is installed between the storage tank and both the three-way gas valve and the one-way valve. The gas inside the vertical air duct passes through the one-way valve, the storage tank, and the installation bend before entering the three-way gas valve, causing the odorous gas to dry the user's hands. The user's hands are then contaminated with the odor. A waste liquid tank is installed at the bottom of the handwashing chamber. The waste liquid tank is equipped with a partition plate and a plastic mesh plate. The disinfectant water is filtered by the plastic mesh plate installed at the top of the waste liquid tank. Two electromagnets are installed between the plastic mesh plate and the partition plate.

[0006] Preferably, the normally open end of the liquid three-way valve is fixedly connected to an inlet pipe, and the normally closed end of the liquid three-way valve is fixedly connected to a water inlet pipe. A water guide bend is fixedly connected between the water pump and the atomizing nozzle. Water is pumped into the atomizing nozzle through the water guide bend, and the disinfectant is finally atomized by the atomizing nozzle and sprayed onto the user's hand. The atomizing nozzle and the top of the sensor are both installed inside the housing. The water pump and the air pump are both fixedly connected inside the housing. A first button and a second button are fixedly connected inside the housing. After pressing the first button, which is electrically connected to the heating wire, the heating wire is in a ready-to-work state.

[0007] Preferably, two sealing rings are fixedly sleeved on the outside of the heating bend, and the heating bend, the two sealing rings, and the air guide box form a sealed space. The heating wire works inside the sealed space to heat the liquid inside the sealed space. The two sealing rings are fixedly connected to the bottom and top of the inner cavity of the air guide box, respectively. The air guide box is sleeved on the outside of the heating wire. After being heated, the liquid exchanges heat with the water and disinfectant flowing inside the heating bend to achieve the effect of heating the water and disinfectant. A bottom pipe is fixedly connected between the bottom of the air guide box and the air guide vertical pipe.

[0008] Preferably, an air inlet pipe is fixedly connected to the top of the air guide box, and a filter box is fixedly connected to one end of the air inlet pipe. One end of the filter box penetrates through the outer shell and is fixedly connected to the outer shell. A filter screen is fixedly connected inside the filter box. After the gas is filtered by the filter screen, it enters the interior of the air guide box through the air inlet pipe.

[0009] Preferably, a gas guide bend is fixedly connected between the gas three-way valve and the air pump. The gas is ultimately drawn by the air pump through the gas three-way valve and the gas guide bend. A gas guide pipe is fixedly connected between the air pump and the gas nozzle. Threaded pipes are fixedly connected to one end of the gas three-way valve and one end of the check valve. After the gas inside the gas guide vertical pipe enters the storage tank through the check valve and the mounting bend, it enters the gas three-way valve through the mounting bend at the top of the storage tank. Nuts are provided between the two mounting bends and the two threaded pipes respectively. Rotating the nuts away from the outside of the threaded pipes removes the fixing between the mounting bends and the threaded pipes.

[0010] Preferably, a T-shaped plate is fixedly connected to the top of the inner cavity of the outer shell. The T-shaped plate supports the bottom of the top cover to prevent the top of the top cover from deforming and denting under stress. A top cover is provided on the top of the outer shell. Insert plates are fixedly connected to both sides of the bottom of the top cover. Threaded grooves are provided on both the insert plates and the outer shell. The mounting bolts leave from the threaded grooves on the insert plates and the outer shell, so that the fixing between the insert plates and the outer shell is removed. Mounting bolts are provided between the insert plates and the outer shell. Storage tubes are fixedly connected to both sides of the outer shell.

[0011] Preferably, a mounting bracket is fixedly connected to one side of the housing, and two hooks are sleeved on the outside of the mounting bracket. Pulling the hooks can move the hooks outside the mounting bracket and adjust the distance between the two hooks.

[0012] Preferably, the partition plate is fixedly connected to the bottom of the waste liquid tank cavity, and a waste discharge pipe is fixedly connected between the partition plate and the outer shell. The disinfectant water is filtered by the plastic mesh plate set at the top of the waste liquid tank cavity and falls into the partition plate. Under the guidance of the waste discharge pipe, the used water and disinfectant are discharged. The plastic mesh plate is set at the top of the waste liquid tank cavity, and multiple sponge blocks are fixedly connected to the top of the plastic mesh plate. The multiple sponge blocks absorb the sprayed water and disinfectant, reducing the possibility of water and disinfectant splashing out of the handwashing cavity.

[0013] Preferably, limiting vertical plates are fixedly connected to both sides of the bottom of the plastic mesh plate. The limiting vertical plates are in contact with the waste liquid tank to limit the movement of the plastic mesh plate. Pushing springs are fixedly connected to both sides of the top of the partition plate. The rebounding pushing springs push the plastic mesh plate upward inside the waste liquid tank, causing the sponge block to move out of the waste liquid tank. The electromagnet is fixedly connected to the top of the partition plate. An iron plate is fixedly connected to the bottom of the plastic mesh plate. The iron plate is set on top of the electromagnet to remove the plastic mesh plate from the inside of the waste liquid tank, which facilitates thorough cleaning of the plastic mesh plate, sponge block and partition plate.

[0014] A hand disinfection method includes the following steps: Step 1: The user faces the handwashing chamber on the outer shell. After inserting both hands into the right side of the handwashing chamber, the water pump starts to draw up disinfectant and pour it into the atomizing nozzle. The disinfectant is then atomized by the atomizing nozzle and sprayed onto the user's hands. Subsequently, the water pump and liquid three-way valve work simultaneously to draw up water and deliver it to the atomizing nozzle. The water is atomized by the atomizing nozzle and sprayed onto the user's hands to rinse them. Step 2: The user moves their hand to the bottom of the auxiliary sensor. The air pump draws in gas and discharges it through the gas nozzle. The gas is sprayed onto the user's hand to dry it. Step 3: After pressing the first button, the heating wire is in the ready-to-work state. Once the sensor or auxiliary sensor detects the user's hand at the bottom, the heating wire will start working. When the heating wire is working, it heats the water and disinfectant inside the heating bend, as well as the gas flowing inside the air guide box. The water and disinfectant sprayed from the atomizing nozzle and the gas sprayed from the gas nozzle are all heated to ensure the user's comfort when using the hand disinfection device in low-temperature winter environments. Step 4: Press the second button. The gas three-way valve and one-way valve will work. The gas inside the storage tank will be delivered by the air pump to the gas nozzle and sprayed onto the user's hands. The gas with scent will dry the user's hands and improve the user experience.

[0015] This invention provides a hand disinfection device and a disinfection method thereof, which have the following beneficial effects: 1. This hand disinfection device and its disinfection method complete hand disinfection, rinsing and drying inside the handwashing chamber set in the outer shell. The hand disinfection device, composed of components such as the outer shell, sensor, atomizing nozzle, water pump, heating bend, liquid three-way valve, gas nozzle, auxiliary sensor, air pump, and air guide vertical pipe, integrates disinfection, rinsing and drying functions, reducing the need for post-disinfection processing and ensuring the convenience of using the hand disinfection device.

[0016] 2. This hand sanitizing device and its disinfection method involve a water pump drawing disinfectant through a heated bend, a liquid three-way valve, and an inlet pipe. The disinfectant is then supplied to the atomizing nozzle via a water guide bend. The disinfectant is atomized by the atomizing nozzle and sprayed onto the user's hands. When the water pump finishes its operation, the water pump and the liquid three-way valve, electrically connected to a sensor, operate synchronously. The normally closed end of the liquid three-way valve opens, and the inlet pipe, fixed to the normally closed end of the liquid three-way valve, connects to the water supply system. At this time, the water pump draws water through the heated bend, the liquid three-way valve, and the inlet pipe, and then supplies it to the atomizing nozzle via the water guide bend. The water is atomized by the atomizing nozzle and sprayed onto the user's hands for rinsing. This integrated design of hand disinfection and rinsing prevents disinfectant residue from sticking to the user's hands, thus avoiding the need for subsequent handwashing.

[0017] 3. The hand disinfection device and its disinfection method: After the user's hands are rinsed with water, the user moves the hands to the left side of the handwashing chamber. The auxiliary sensor detects the user's hands at the bottom. The air pump electrically connected to the auxiliary sensor works to draw gas through the air guide bend, gas three-way valve, air guide vertical pipe, bottom pipe and air guide box, and then discharges the gas through the gas nozzle. The gas is sprayed onto the user's hands by the gas nozzle to dry the user's hands.

[0018] 4. This hand sanitizing device and its method involve pressing the first button electrically connected to the heating wire. After the sensor or auxiliary sensor detects the user's hand at the bottom, the heating wire activates, heating the liquid filling the space between the air guide box and the heating bend. The water and disinfectant inside the heating bend, as well as the gas in the air guide box whose flow is restricted by the spiral blades, are all heated by the liquid heated by the heating wire. This ensures that the water and disinfectant sprayed from the atomizing nozzle and the gas sprayed from the gas nozzle are heated, guaranteeing user comfort when using the hand sanitizing device in low-temperature winter environments.

[0019] 5. This hand sanitizing device and its sanitizing method: After pressing the second button, the gas three-way valve and one-way valve are activated. At this time, the normally closed end of the gas three-way valve opens and connects to the storage tank through the installed elbow. Finally, the gas inside the storage tank is delivered by the air pump to the gas nozzle and sprayed onto the user's hands, which dries the user's hands with odor-containing gas, and the user's hands are imbued with the odor, increasing the user's experience.

[0020] 6. This hand disinfection equipment and its disinfection method allow the fixing between the installed bend and the threaded pipe to be removed by rotating the nut away from the outside of the threaded pipe. This allows the storage box to be disassembled, ensuring convenient and quick replacement of the storage box, and allowing the gas sprayed from the gas nozzle to have different odors.

[0021] 7. Multiple sponge blocks are fixedly connected to the top of the plastic mesh panel. These sponge blocks absorb the sprayed water and disinfectant, reducing the possibility of splashing water and disinfectant into the handwashing chamber. After the hand sanitizing device is powered off, the rebounding spring pushes the plastic mesh panel upwards inside the waste liquid tank, causing the sponge blocks to move out of the waste liquid tank. At this point, staff can easily remove the plastic mesh panel from the waste liquid tank, facilitating thorough cleaning of the plastic mesh panel, sponge blocks, and divider.

[0024] This invention provides a hand disinfection device and a disinfection method thereof.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14The device includes an outer casing 1. A handwashing chamber 47 is located on the front side of the outer casing 1. Atomizing nozzles 9 and gas nozzles 24 are respectively located on the top two sides of the handwashing chamber 47. Sensors 8 and auxiliary sensors 25 are respectively located on the front sides of the atomizing nozzles 9 and 24. A water pump 10 is located on one side of the top of the atomizing nozzles 9. A water guide bend 11 is fixedly connected between the water pump 10 and the atomizing nozzles 9. The tops of the atomizing nozzles 9 and the sensors 8 are both located inside the outer casing 1. A heating bend 12 is fixedly connected to one end of the water pump 10. A liquid three-way valve 17 is fixedly connected to the bottom of the heating bend 12. An inlet pipe 18 is fixedly connected to the normally open end of the liquid three-way valve 17, and a water inlet pipe 19 is fixedly connected to the normally closed end of the liquid three-way valve 17. A heating wire 13 and a gas guide box 15 are sleeved on the outside of the heating bend 12. A spiral blade 16 is fixedly connected inside the gas guide box 15. A vertical air duct 21 is provided on one side of the air duct box 15. A three-way gas valve 22 is fixedly connected to the top of the vertical air duct 21. An air pump 23 is provided between the top of the three-way gas valve 22 and the gas nozzle 24. The water pump 10 and the air pump 23 are both fixedly connected inside the outer casing 1. A first button 48 and a second button 49 are fixedly connected inside the outer casing 1. A one-way valve 33 is fixedly connected to one side of the vertical air duct 21. A storage tank 35 is provided on one side of the three-way gas valve 22. An installation bend 36 is provided between the storage tank 35 and the three-way gas valve 22 and the one-way valve 33. A waste liquid tank 38 is provided at the bottom of the inner cavity of the handwashing chamber 47. A partition plate 39 and a plastic mesh plate 43 are provided inside the waste liquid tank 38. Two electromagnets 41 are provided between the plastic mesh plate 43 and the partition plate 39. A bottom pipe 20 is fixedly connected between the bottom of the air duct box 15 and the vertical air duct 21.

[0026] Specifically, when the user faces the handwashing chamber 47 located on the outer casing 1 and inserts both hands into the right side of the handwashing chamber 47, the sensor 8 detects the user's hands at the bottom. The water pump 10, electrically connected to the sensor 8, operates for a period of time and then stops. This is because the water pump 10 is fixedly connected to the liquid three-way valve 17 via a heating bend 12, and the liquid three-way valve 17 is connected to the disinfectant storage location via an inlet pipe 18. Therefore, the operating water pump 10 draws the disinfectant through the heating bend 12, the liquid three-way valve 17, and the inlet pipe 18, and then pumps it to the atomizing nozzle 9 through the water guide bend 11. The disinfectant is ultimately atomized by the atomizing nozzle 9 and sprayed onto the user's hands. When the water pump 10 stops operating, the water pump 10 and the liquid three-way valve 17, electrically connected to the sensor 8, operate synchronously. The normally closed end of the operating liquid three-way valve 17 opens, and the inlet pipe 19, fixed to the normally closed end of the liquid three-way valve 17, connects to the water supply system. The water pump 10, which is currently in operation, draws water through the heating bend 12, the liquid three-way valve 17, and the water inlet pipe 19, and then delivers it to the atomizing nozzle 9 through the water guide bend 11. The water is atomized by the atomizing nozzle 9 and sprayed onto the user's hands to rinse them. The structure for disinfecting and rinsing the user's hands is integrated into one unit, avoiding the sticking of disinfectant to the user's hands and eliminating the need for the user to wash their hands again later.

[0027] An auxiliary sensor 25 is installed on the top left side of the handwashing chamber 47. After the user's hands are rinsed with water, they move their hands to the left side inside the handwashing chamber 47. The auxiliary sensor 25 detects the user's hands at the bottom, and the air pump 23, which is electrically connected to the auxiliary sensor 25, works to draw gas through the air guide bend 26, gas three-way valve 22, air guide riser 21, bottom pipe 20, and air guide box 15. The gas is then discharged through the gas nozzle 24 and sprayed onto the user's hands to dry them. Hand disinfection, rinsing, and drying are completed inside the handwashing chamber 47 in the outer shell 1. The hand disinfection device, composed of the outer shell 1, sensor 8, atomizing nozzle 9, water pump 10, heating bend 12, liquid three-way valve 17, gas nozzle 24, auxiliary sensor 25, air pump 23, and air guide riser 21, integrates disinfection, rinsing, and drying functions, reducing the need for post-disinfection processing and ensuring the ease of use of the hand disinfection device.

[0028] A heating wire 13 is fixedly connected to the outside of the heating bend 12. Therefore, after pressing the first button 48 electrically connected to the heating wire 13, the heating wire 13 is in a ready-to-work state. After the sensor 8 or auxiliary sensor 25 detects the user's hand at the bottom, the heating wire 13 electrically connected to the sensor 8 and auxiliary sensor 25 will start working. The air guide box 15 is sleeved on the outside of the heating wire 13, so the liquid filled between the air guide box 15 and the heating bend 12 is heated when the heating wire 13 is working. The water and disinfectant inside the heating bend 12, as well as the gas in the air guide box 15 that is restricted to spiral flow by the spiral blade 16, can all be heated by the liquid heated by the heating wire 13. This ensures that the water and disinfectant sprayed from the atomizing nozzle 9 and the gas sprayed from the gas nozzle 24 are heated, guaranteeing the user's comfort when using the hand disinfection device in low-temperature winter environments.

[0029] Furthermore, both the three-way gas valve 22 and the one-way valve 33 are electrically connected to the second button 49. Pressing the second button 49 activates the three-way gas valve 22 and the one-way valve 33. At this time, the normally closed end of the three-way gas valve 22 opens and connects to the storage tank 35 through the mounting bend 36. Therefore, the gas inside the air guide pipe 21 enters the three-way gas valve 22 after passing through the one-way valve 33, the storage tank 35, and the mounting bend 36. Finally, the gas inside the storage tank 35 is delivered by the air pump 23 to the gas nozzle 24 and sprayed onto the user's hands. The storage tank 35 contains a stimulating substance such as mint to give the gas an odor, allowing the scented gas to dry the user's hands and enhance the user experience.

[0030] Please refer to it again. Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 Two sealing rings 14 are fixedly sleeved on the outside of the heating bend 12. The two sealing rings 14 are fixedly connected to the bottom and top of the inner cavity of the air guide box 15, respectively. An air inlet pipe 30 is fixedly connected to the top of the air guide box 15. A filter box 31 is fixedly connected to one end of the air inlet pipe 30. One end of the filter box 31 passes through the outer shell 1 and is fixedly connected to the outer shell 1. A filter screen 32 is fixedly connected inside the filter box 31. The air guide box 15 is sleeved on the outside of the heating wire 13. An air guide bend 26 is fixedly connected between the gas three-way valve 22 and the air pump 23. An air guide pipe 27 is fixedly connected between the air pump 23 and the gas nozzle 24. A threaded pipe 34 is fixedly connected to one end of the gas three-way valve 22 and one end of the one-way valve 33. Nuts 37 are provided between the two mounting bends 36 and the two threaded pipes 34, respectively.

[0031] Specifically, a sealed space is formed by the heating bend 12, two sealing rings 14, and the air guide box 15. The heating wire 13 operates inside this sealed space to heat the liquid inside. After being heated, the liquid exchanges heat with the water and disinfectant flowing inside the heating bend 12, achieving the effect of heating the water and disinfectant. Furthermore, a spiral blade 16 is fixedly connected inside the air guide box 15. Therefore, after the gas enters the air guide box 15, it is guided by the spiral blade 16, causing the gas to move along a spiral downward path, increasing the time for heat exchange between the gas and the liquid inside the sealed space, and ensuring that the gas is heated.

[0032] A filter box 31 is fixedly connected to the top of the air guide box 15 via an air inlet pipe 30, and a filter screen 32 is fixedly connected inside the filter box 31. Therefore, after the gas is filtered by the filter screen 32, it enters the air guide box 15 through the air inlet pipe 30. The gas is then guided into the air guide vertical pipe 21 through the bottom pipe 20 fixedly connected to the bottom of the air guide box 15. A gas guide bend 26 is fixedly connected between the gas three-way valve 22 fixed to the air guide vertical pipe 21 and the air pump 23. Finally, the gas is drawn by the air pump 23 through the gas three-way valve 22 and the gas guide bend 26.

[0033] When the one-way valve 33 and the three-way gas valve 22 are working, because the storage tank 35 is connected to both the three-way gas valve 22 and the one-way valve 33 by mounting bends 36, and the two mounting bends 36 are respectively aligned with the threaded pipes 34 that fix the three-way gas valve 22 and the one-way valve 33, the gas inside the air guide pipe 21 enters the storage tank 35 through the one-way valve 33 and the mounting bends 36, and then enters the three-way gas valve 22 through the mounting bends 36 at the top of the storage tank 35, so that it can be drawn by the air pump 23. Furthermore, a nut 37 is threadedly connected between the threaded pipe 34 and the mounting bend 36. By rotating the nut 37 away from the outside of the threaded pipe 34, the fixing between the mounting bend 36 and the threaded pipe 34 can be removed, allowing the storage tank 35 to be disassembled, ensuring convenient and quick replacement of the storage tank 35, and allowing the gas sprayed from the gas nozzle 24 to have different odors.

[0034] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A T-shaped plate is fixedly connected to the top of the inner cavity of the outer shell 1. A mounting bracket 6 is fixedly connected to one side of the outer shell 1. Two hooks 7 are sleeved on the outside of the mounting bracket 6. A top cover 2 is provided on the top of the outer shell 1. Insert plates 3 are fixedly connected to both sides of the bottom of the top cover 2. Threaded grooves are provided on both the insert plates 3 and the outer shell 1. Mounting bolts 5 are provided between the insert plates 3 and the outer shell 1. Storage tubes 4 are fixedly connected to both sides of the outer shell 1.

[0035] Specifically, a hook 7 is fitted onto the outside of the mounting bracket 6 installed on the outer shell 1. The rubber hook 7 is elastically deformable and has a large frictional force with the mounting bracket 6. Therefore, when the worker pulls the hook 7, the hook 7 can move outside the mounting bracket 6, adjusting the distance between the two hooks 7 so that the hook 7 can adapt to the hanging of different items.

[0036] Rotate the mounting bolt 5 away from the inside of the receiving tube 4. The mounting bolt 5 also leaves the threaded grooves in the insert plate 3 and the outer shell 1, thus removing the fixing between the insert plate 3 and the outer shell 1. The top cover 2 can then be removed from the top of the outer shell 1, allowing workers to perform maintenance on the inside of the outer shell 1. The T-shaped plate fixed inside the outer shell 1 supports the bottom of the top cover 2, preventing the top of the top cover 2 from deforming or denting under stress.

[0037] Please refer to it again. Figure 1 , Figure 5 and Figure 14The partition plate 39 is fixedly connected to the bottom of the inner cavity of the waste liquid tank 38. A waste discharge pipe 40 is fixedly connected between the partition plate 39 and the outer shell 1. The plastic mesh plate 43 is set at the top of the inner cavity of the waste liquid tank 38. Multiple sponge blocks 44 are fixedly connected to the top of the plastic mesh plate 43. Limiting vertical plates 45 are fixedly connected to both sides of the bottom of the plastic mesh plate 43. Push-out springs 46 are fixedly connected to both sides of the top of the partition plate 39. The electromagnet 41 is fixedly connected to the top of the partition plate 39. An iron plate 42 is fixedly connected to the bottom of the plastic mesh plate 43. The iron plate 42 is set at the top of the electromagnet 41.

[0038] Specifically, the water and disinfectant sprayed from the atomizing nozzle 9 falls into the waste liquid tank 38. The disinfectant water is filtered by the plastic mesh plate 43 set at the top of the inner cavity of the waste liquid tank 38 and then falls into the partition plate 39. Under the guidance of the waste discharge pipe 40, the used water and disinfectant are discharged. Multiple sponge blocks 44 are fixedly connected to the top of the plastic mesh plate 43. The sponge blocks 44 absorb the sprayed water and disinfectant, reducing the possibility of water and disinfectant splashing out of the handwashing cavity 47. When the hand sanitizing device is powered off, the electromagnet 41 stops working. The deactivated electromagnet 41 no longer attracts the fixed iron plate 42, and the rebounding spring 46 pushes the plastic mesh plate 43 upward inside the waste liquid tank 38, causing the sponge blocks 44 to move out of the waste liquid tank 38. At this time, the staff can easily remove the plastic mesh plate 43 from the waste liquid tank 38, facilitating thorough cleaning of the plastic mesh plate 43, sponge blocks 44, and partition plate 39.

[0039] Furthermore, the limiting vertical plate 45, which is fixedly connected to the plastic mesh plate 43, is attached to the waste liquid tank 38 to limit the movement of the plastic mesh plate 43 and ensure that the plastic mesh plate 43 moves horizontally inside the waste liquid tank 38.

[0040] The gas nozzle 24 can be controlled to work for a long time during a certain period of time. The gas blown out by the gas nozzle 24 dries the waste liquid tank 38, plastic mesh plate 43 and sponge block 44, reducing the frequency of cleaning the waste liquid tank 38, plastic mesh plate 43 and sponge block 44.

[0041] A hand disinfection method includes the following steps: Step 1: After the user inserts both hands into the right side of the handwashing chamber 47, the sensor 8 that detects the hands controls the electrically connected water pump 10 to operate, drawing up disinfectant and pouring it into the atomizing nozzle 9. The disinfectant is then atomized by the atomizing nozzle 9 and sprayed onto the user's hands, thus disinfecting the user's hands.

[0042] After a period of time, the water pump 10 and the liquid three-way valve 17 work synchronously again, drawing water and delivering it to the atomizing nozzle 9. The water is atomized by the atomizing nozzle 9 and sprayed onto the user's hands to rinse the user's hands and wash away the disinfectant. This integrated disinfection and cleaning system reduces equipment costs and avoids wasting time that users would otherwise have to wash off the disinfectant from their hands.

[0043] Step 2: After the user moves their hand to the bottom of the auxiliary sensor 25, the air pump 23 electrically connected to the auxiliary sensor 25 starts to draw gas and discharge it through the gas nozzle 24. The gas is sprayed onto the user's hand by the gas nozzle 24 to dry the user's hand. The housing 1 is equipped with disinfection, cleaning and drying functions to ensure the user's comfort. Step 3: In cold weather, after pressing the first button 48 in advance, the heating wire 13 is in a ready-to-work state. Once the sensor 8 or auxiliary sensor 25 detects the user's hand at the bottom, the heating wire 13 will activate. The activated heating wire 13 heats the water and disinfectant inside the heating bend 12, and simultaneously heats the gas flowing inside the air guide box 15. The water and disinfectant sprayed from the atomizing nozzle 9, and the gas sprayed from the gas nozzle 24, are all heated to meet the needs of winter use. This ensures user comfort when using the hand sanitizing device in low-temperature winter environments, improves the adaptability of the hand sanitizing device, and enhances its practicality. Step 4: Press the second button 49. The gas three-way valve 22 and one-way valve 33 will activate, and the gas inside the storage tank 35 will be pumped by the air pump 23 to the gas nozzle 24 and sprayed onto the user's hands. The scented gas will dry the user's hands, improving the user experience. Step 4 serves as an auxiliary option to Step 2 and can be used in any situation according to the user's needs, meeting the needs of places such as office buildings and hospitals where it is necessary to mask hand odors and ensuring a positive user experience for the hand disinfection equipment.
