[0002] Sterilizers include hydrogen peroxide sterilizers, which are highly efficient sterilization equipment. The main principle of the sterilizer is to achieve disinfection by vaporizing hydrogen peroxide. The working principle of the sterilizer is to convert hydrogen peroxide liquid into gas and diffuse it in the air, thereby killing viruses and bacteria in the air. This sterilization method has the characteristics of broad-spectrum antibacterial and high-efficiency sterilization, and can quickly kill a variety of pathogens, including bacteria, viruses and fungi.

[0003] The sterilizer generally includes a walking unit, a hydrogen peroxide storage unit, a hydrogen peroxide vaporization unit, an electrical control unit, a nozzle assembly and a ventilation assembly.

[0055] The setting of the baffle 43 in the flash evaporation shell 401 allows the flash evaporation assembly 44 to be placed in a separate chamber, which can make the vaporization of the hydrogen peroxide liquid more thorough. The vaporized hydrogen peroxide enters the second chamber 42 through the connecting hole on the baffle 43, and then enters the nozzle assembly 2 through the outlet 452 on the wall of the second chamber 42, and then is discharged into the room through the nozzle assembly 2 to start sterilization and disinfection, thereby preventing the hydrogen peroxide solution from immediately entering the nozzle assembly 2 through the outlet 452 on the flash evaporation shell 401 as soon as it contacts the flash evaporation assembly 44, thereby meeting the concentration requirement for hydrogen peroxide sterilization, improving the utilization rate of hydrogen peroxide, reducing the input amount of hydrogen peroxide, and saving costs.

[0056] In the vertical direction, the second chamber 42 is located above the first chamber 41, and the liquid spraying end 502 can pass through the side wall of the second chamber 42 and the baffle 43 in sequence and be placed in the first chamber 41, and the liquid spraying end 502 is arranged opposite to the flash assembly 44, so that the hydrogen peroxide liquid can be sprayed to the flash assembly 44. In order to fully vaporize the hydrogen peroxide, the outlet 452 and the first chamber 41 are staggered in the axial direction of the liquid spraying end 502.

[0057] like Figure 1 and Figure 2 As shown, the sterilizer housing 1 is also provided with ventilation holes and an inspection panel.

In other embodiments, other numbers of ventilation holes may be provided; the inspection panel is provided on the housing 1, which can facilitate the staff to inspect when the sterilizer fails.

[0058] The sterilizer provided in this embodiment also includes a walking unit 10, which includes a walking wheel assembly and an ultrasonic probe 1001. The walking wheel assembly is arranged below the housing 1, and plays a role in supporting the entire instrument and driving the sterilizer to move indoors. In this embodiment, the ultrasonic probe 1001 is arranged on the housing 1, and along the direction in which the sterilizer moves, the ultrasonic probe 1001 is located at the upper and lower parts of the front side of the housing 1, which can realize all-round detection up and down, making the sterilizer move more smoothly.

[0059] Specifically, the housing 1 is provided with a mounting box 103 for mounting an ultrasonic probe 1001 located at the upper part of the housing 1 and a gas detection element 102 for detecting the concentration of hydrogen peroxide in the room. The housing 1 is provided with an electrical control system 11, which controls the movement of the walking unit 10, and detects the size of the room, the wall and the obstacles in front through the upper and lower ultrasonic probes 1001. The walking unit 10 is also provided with a light strip, which is used as a working status prompt of the sterilizer. The light strip displays different colors when the sterilizer is in different working states. The sterilizer can be moved to every corner of the room that needs to be disinfected, so that there is no dead angle in the entire sterilization process, and the sterilization is more thorough and does not require human intervention.

[0060] like Figure 2 , Figure 3 and Figure 4 As shown, a liquid supply unit 3 for providing liquid for vaporization of hydrogen peroxide is provided inside the housing 1 of the sterilizer, and the liquid supply unit 3 includes a nozzle assembly 5, and the liquid supply unit 3 also includes a liquid storage bottle 31 for storing hydrogen peroxide liquid, a liquid supply pump 32 for pumping the hydrogen peroxide liquid to the vaporization unit 4, and an air supply pump 33 that can smoothly drip the liquid into the vaporization unit 4. One end of the liquid supply pump 32 is connected to the liquid storage bottle 31, and the other end of the liquid supply pump 32 is connected to the inlet end 501 of the nozzle assembly 5. One end of the air supply pump 33 is connected to the inlet end 501 of the nozzle assembly 5, and the other end is connected to the external environment. The liquid supply pump 32 transports the hydrogen peroxide in the liquid storage bottle 31 to the liquid spraying end 502 of the nozzle assembly 5, and the air supply pump 33 pumps air into the nozzle assembly 5, so that the hydrogen peroxide liquid can be dispersed and smoothly flow out of the nozzle assembly 5.

[0061] Specifically, a liquid supply hose is provided in the housing 1 , and a hose connector is connected to the liquid supply hose. The liquid supply pump 32 is connected to the liquid storage bottle 31 through the liquid supply hose to pump the hydrogen peroxide liquid in the liquid storage bottle 31 into the nozzle assembly 5 .

[0062] In this embodiment, the liquid supply unit 3 also includes a support seat 37 and a placement box 34 rotatably connected to the support seat 37. The support seat 37 is fixed to the inside of the shell 1 to support and fix the placement box 34. The liquid storage bottle 31 is placed in the placement box 34. The rotation of the placement box 34 can make the liquid storage bottle 31 placed inside the shell 1 or outside the shell 1 to achieve the purpose of replacing the liquid storage bottle 31. A first magnetic component 351 is provided on the outer side of the bottom of the placement box 34, and a second magnetic component 352 is provided on the support seat 37. The second magnetic component 352 can be attracted to the first magnetic component 351, and the first magnetic component 351 and the second magnetic component 352 fix the placement box 34 through magnetic constraints. Specifically, as Figure 5 As shown, the rotating shaft 36 is arranged on the support seat 37, and the placement box 34 is provided with a sleeve that matches the rotating shaft 36. The sleeve is rotatably sleeved on the rotating shaft 36, and the rotation direction of the rotating shaft 36 is arranged in the horizontal direction. The placement box 34 can be rotated to separate the first magnetic member 351 from the second magnetic member 352, so that the placement box 34 can be rotated on the support seat 37 to tilt the liquid storage bottle 31 to the outside of the housing 1, and then replace the liquid storage bottle 31. After the placement box 34 is reset, the liquid storage bottle 31 is placed inside the housing 1, and the first magnetic member 351 and the second magnetic member 352 are attracted.

[0063] Furthermore, in this embodiment, a handle is provided on the placement box 34 for realizing quick replacement of the liquid storage bottle 31, which is convenient for the operator. Specifically, the handle is welded on the placement box 34. When taking out the bottle, the handle is pulled to separate the first magnetic member 351 and the second magnetic member 352. The placement box 34 rotates through the rotating shaft 36, and after the liquid storage bottle 31 is tilted to a certain angle, the liquid storage bottle 31 can be taken out, realizing quick replacement of the liquid storage bottle 31.

[0064] Furthermore, combined with Figure 4 and Figure 5 As shown, in order to intuitively and accurately obtain the remaining amount of liquid in the liquid storage bottle 31, the liquid supply unit 3 also includes a weighing piece 38, which is arranged below the support seat 37 and is used to weigh the remaining amount of hydrogen peroxide in the liquid storage bottle 31. A glass door is provided at a position corresponding to the liquid storage bottle 31 on the housing 1, which can be used to assist in observing the remaining amount of hydrogen peroxide in the liquid storage bottle 31. Specifically, the weighed data can be sent to the remote control end through the electrical control system 11, so that the user can check the remaining amount at any time, so as to achieve the purpose of facilitating the user to replace the liquid storage bottle 31 in time.

[0065] Combination Figure 3As shown, a portion of the exterior of the flash shell 401 of the sterilizer is also wrapped with a heat insulation board 402, which is used to prevent the temperature of the flash shell 401 from losing and scalding the operator. Specifically, the heat insulation board 402 is connected to a movable cover at the top of the flash shell 401, and the movable cover is used to install the fixed nozzle assembly 5. The heat insulation board 402 is provided with an opening at the top of the flash shell 401 for installing the movable cover, and a heat insulation pad is provided at the connection between the heat insulation board 402 and the movable cover to prevent the temperature of the flash shell 401 at the connection position from losing and scalding the operator.

[0066] The setting of the baffle 43 allows the flash assembly 44 to be placed in a separate chamber, so that the hydrogen peroxide can enter the second chamber 42 through the connecting hole on the baffle 43 after being fully vaporized, and then enter the nozzle assembly 2 through the outlet 452 on the wall of the second chamber 42 to be discharged into the external environment, thereby preventing the hydrogen peroxide solution from immediately entering the nozzle assembly 2 through the outlet 452 on the flash shell 401 as soon as it contacts the flash assembly 44, and then being discharged into the external environment. The setting of the baffle 43 optimizes the vaporization structure, makes the vaporization of hydrogen peroxide more thorough, improves the utilization rate of hydrogen peroxide, reduces the input amount of hydrogen peroxide, and saves costs.

[0067] Combination Figure 3 and Figure 6 As shown, the flash assembly 44 is detachably connected to the flash shell 401, and the flash assembly 44 includes an outer cover plate 441, a flash plate 444, a first thermal insulation pad 442 and a second thermal insulation pad 443. The outer cover plate 441 is detachably arranged on the outer side of the shell 1; the first thermal insulation pad 442 is detachably connected to the outer cover plate 441 and is placed between the outer cover plate 441 and the flash shell 401, and is used to prevent the heat of the flash plate 444 as a whole from being transferred to the outer cover plate 441 to scald the operator, and to prevent heat loss. The first thermal insulation pad 442 is provided with a groove, and the groove is used to embed the flash plate 444, so that the connection between the flash plate 444 and the outer cover plate 441 is more stable; the second thermal insulation pad 443 is arranged in the groove, and is used to prevent the heat at the end of the flash plate 444 from being transferred to the outer cover plate 441 to scald the operator, and to cause heat loss.

[0068] One end of the flash evaporation plate 444 is placed in the groove and the end is abutted against the second insulation pad 443, and the other end of the flash evaporation plate 444 is passed through the flash evaporation shell 401 and placed in the first chamber 41. Specifically, a heating device is provided in the flash evaporation plate 444, and after the hydrogen peroxide liquid drips onto the flash evaporation plate 444, the hydrogen peroxide is vaporized by high temperature. The second insulation pad 443 abuts against the side of the flash evaporation plate 444 where the heating device is provided, further preventing the heat of the flash evaporation plate 444 from being transferred to the outside. The flash evaporation assembly 44 is detachably arranged in the flash evaporation shell 401, and the flash evaporation plate 444 with scaling can be easily replaced or cleaned, so that the vaporization effect is maintained in a good state for a long time.

[0069] Specifically, a plurality of interconnected screw holes are respectively provided on the outer cover plate 441 and the first thermal insulation pad 442. The screws are passed through the outer cover plate 441 and the first thermal insulation pad 442 to connect the outer cover plate 441 and the flash evaporation plate 444. Then, the flash evaporation assembly 44 is integrally locked to the side wall of the first chamber 41 of the flash evaporation shell 401 by nuts, so that the outer cover plate 441 and the nuts are exposed to the flash evaporation shell 401. When the flash evaporation plate 444 needs to be replaced and cleaned, the flash evaporation assembly 44 can be disassembled by removing the nuts, which is convenient for replacing and cleaning the flash evaporation plate 444 with scaling. In the present embodiment, two interconnected screw holes are respectively provided on the outer cover plate 441 and the first thermal insulation pad 442. In other embodiments, other numbers of screw holes may also be provided.

[0070] Furthermore, combined with Figure 2 , Figure 3 and Figure 4 As shown, the nozzle assembly 5 is used to connect the liquid supply unit 3 and the vaporization unit 4, so that the hydrogen peroxide liquid drips onto the flash disk 444 in the flash shell 401 to complete the vaporization process. The liquid spraying end 502 of the nozzle assembly 5 penetrates the outer wall of the top of the second chamber 42 and the baffle 43 and is placed in the first chamber 41. The inlet end 501 of the nozzle assembly 5 is provided with a three-way structure for connecting the liquid supply pump 32 and the air supply pump 33 of the liquid supply unit 3. The liquid spraying end 502 of the nozzle assembly 5 is arranged in the first chamber 41 and is arranged opposite to the flash assembly 44, so as to make the hydrogen peroxide liquid drip directly onto the flash disk 444, and enter the second chamber 42 after being fully vaporized, so as to reduce the influence of the fast-flowing air on the hydrogen peroxide liquid at the nozzle outlet 452, and improve the flash evaporation effect.

[0071] Furthermore, if Figure 2 , Figure 7 and Figure 8 As shown, in order to improve the sterilization efficiency and allow the vaporized hydrogen peroxide to be quickly and evenly discharged into the external environment, a ventilation unit 6 is also provided in the housing 1. Specifically, in this embodiment, the ventilation unit 6 adopts a fan. The ventilation hole on the housing 1 facing the front is the air inlet 101 of the entire sterilizer. The air inlet end 601 of the ventilation unit 6 is connected with the air inlet 101 on the housing 1, providing support for the ventilation unit 6 to inhale external air. The air outlet end of the ventilation unit 6 is connected with the second chamber 42 of the flash housing 401 through the inlet 451 of the housing 1. The ventilation unit 6 is used to blow air into the second chamber 42, so that the vaporized hydrogen peroxide in the second chamber 42 can circulate quickly, and then blown out from the outlet 452 of the second chamber 42 into the nozzle assembly 2, and then blown into the room to start the disinfection and sterilization work.

[0072] Specifically, a first air outlet duct 901 and a second air outlet duct 902 are provided between the outlet 452 of the second chamber 42 and the nozzle assembly 2. The first air outlet duct 901 is connected to the outlet 452 of the second chamber 42, and the other end of the second air outlet duct 902 is connected to the nozzle assembly 2. The second air outlet duct 902 is a hose. The first air outlet duct 901 and the nozzle assembly 2 are both made of hard materials. The second air outlet duct 902 is a hose to facilitate the connection between the first air outlet duct 901 and the nozzle assembly 2, so that the vaporized hydrogen peroxide is discharged from the outlet 452 on the second chamber 42 through the first ventilation duct and the second ventilation duct to the nozzle assembly 2, and then blown out to the environment that needs to be disinfected.

[0073] like Figure 8 As shown, after the disinfection process is completed, a decomposition unit 7 needs to be set to decompose the excessively high concentration of hydrogen peroxide in the disinfection environment to reduce the damage of high-concentration hydrogen peroxide to the human body. The decomposition unit 7 is arranged in the housing 1 and is slidably connected to the housing 1. A gas detection component 102 is provided on the outside of the housing 1. The gas detection component 102 is configured to detect the indoor hydrogen peroxide concentration so that the decomposition unit 7 slides in or out between the air inlet 101 and the ventilation unit 6. In this embodiment, a decomposition unit 7 that can be lifted and lowered is provided to reduce the indoor hydrogen peroxide concentration. Specifically, a slide rail is provided on the inner side of the housing 1, and the decomposition unit 7 slides on the slide rail through a pulley, so that the decomposition unit 7 slides more smoothly. The gas detection element 102 is used to detect the concentration of hydrogen peroxide in the disinfection environment, and provide guidance for the decomposition of hydrogen peroxide in the environment after disinfection. When the gas detection element 102 detects that the indoor hydrogen peroxide concentration reaches the preset disinfection concentration, the electrical control system 11 controls the liquid supply unit 3 and the vaporization unit 4 to stop working, and controls the decomposition unit 7 to slide between the air inlet 101 and the ventilation unit 6, and perform the decomposition work. By setting the decomposition unit 7 up and down, the decomposition unit 7 can be placed on the same horizontal line with the air inlet 101 and the ventilation unit 6 when working, thereby improving the decomposition efficiency.

[0074] Furthermore, in order to realize the automation of the lifting and lowering of the decomposition unit 7, an electric drive rod 8 is further provided in the housing 1, one end of the electric drive rod 8 is hinged to the decomposition unit 7, and the other end of the electric drive rod 8 is hinged to the inside of the housing 1, and the electric drive rod 8 is used to drive the decomposition unit 7 to slide. Specifically, in this embodiment, a fixed beam is provided in the housing 1, and the electric drive rod 8 is hinged to the fixed beam. The electric drive rod 8 is retractable, and can be retracted when the decomposition unit 7 rises, and extended when the decomposition unit 7 falls, so as to achieve the purpose of saving space. In other embodiments, the driving member can be a cylinder.

[0075] Specifically, during the sterilization process, the decomposition unit 7 is driven by the electric drive rod 8 to the lowest position. After the sterilization process is completed, the gas detection component 102 detects the concentration of hydrogen peroxide in the room after disinfection. The data detected by the gas detection component 102 is fed back to the remote display through the electrical control system 11 for the convenience of the user to view. At this time, the liquid supply unit 3 stops supplying liquid, and the vaporization unit 4 stops working. The electrical control system 11 controls the drive rod to drive the decomposition unit 7 to rise, flush with the air inlet 101 on the shell 1 and the ventilation unit 6. The air inhaled by the ventilation unit 6 first passes through the decomposition unit 7 to decompose the higher concentration of hydrogen peroxide in the air. The decomposed air is inhaled by the air inlet end 601 of the ventilation unit 6, and the decomposed gas flows through the vaporization unit 4, the first air outlet duct 901 and the second air outlet duct 902, and is finally blown out into the air by the ventilation unit 6 at the nozzle assembly 2 to complete the air circulation. The circulation process can be repeated. During the circulation process, the user can check the concentration of hydrogen peroxide in the room at any time until the indoor concentration is decomposed to be harmless to the human body. The user can start and stop the sterilizer through remote control.

[0076] The sterilizer provided in this embodiment also includes a charging port and a battery unit. The charging port is arranged on the shell 1, and the battery unit is arranged inside the shell 1. This can avoid being bound by a power cord when the sterilizer is used indoors for sterilization, and is convenient to use.

[0077] The working principle of the sterilizer of this embodiment is described below:

[0078] After the sterilizer is started, the electrical control system 11 controls the gas detection element 102 to monitor the concentration of hydrogen peroxide in the environment to be disinfected in real time and transmits the data to the remote end; the electrical control system 11 controls the liquid supply unit 3 to supply liquid, and controls the vaporization unit 4 to start working, and the hydrogen peroxide liquid flows from the liquid supply unit 3 through the nozzle assembly 5 and is sprayed to the vaporization unit 4. At the same time, the electrical control system 11 controls the ventilation unit 6 to start, and the ventilation unit 6 blows the vaporized hydrogen peroxide through the nozzle assembly 2 to the environment to be disinfected. After the gas detection element 102 detects that the concentration of hydrogen peroxide in the environment reaches the disinfection standard, the disinfection is completed, and the electrical control System 11 controls the liquid supply unit 3 and the vaporization unit 4 to stop working; at this time, the electrical control system 11 controls the decomposition unit 7 to start, and the decomposition unit 7 rises to a position aligned with the ventilation unit 6 and the air inlet 101. The ventilation unit 6 inhales the air in the disinfected environment and allows the gas to pass through the decomposition unit 7 to complete the decomposition. The decomposed gas flows through the vaporization unit 4 to reach the nozzle assembly 2, and is blown into the external environment by the ventilation unit 6 to complete a decomposition process. The decomposition process is repeated. When the gas detection component 102 detects that the hydrogen peroxide concentration in the environment reaches the safety standard, the electrical control system 11 controls the sterilizer to stop working. During the entire disinfection and sterilization process, the walking unit 10 is always in working condition to achieve sterilization without dead angles.
