An air outlet pipe is provided on the inner wall of the wall-mounted unit housing, and the bottom end of the air outlet pipe is connected to the fan's air outlet. A mist outlet channel housing is installed inside the wall-mounted unit housing. The mist outlet channel housing is provided with an air duct, an atomizing channel, and a blowing channel. The top end of the air outlet pipe is connected to one end of the air duct, and the other end of the air duct is connected to the top end of the atomizing channel. The atomizing channel is located above the atomizing mechanism, and the bottom end of the blowing channel is connected to the top end of the atomizing channel. A spray hole is provided on the top of the front panel of the wall-mounted unit housing, and the top end of the blowing channel is connected to the spray hole.

[0005] Furthermore, the rear panel of the wall-mounted unit casing is provided with wall-mounting slots.

[0006] Furthermore, a filter screen is installed on the bottom wall of the water tank, covering the top of the liquid supply hole.

[0007] Furthermore, the level control valve includes a hinge seat, a plug, a lifting rod, a spring, a lever, and a float. The hinge seat is installed on the inner bottom wall of the atomizing box. The middle part of the lever is hinged to the hinge seat. The lifting rod slides through the liquid supply hole. The plug is installed at the top of the lifting rod and is raised and lowered above the liquid supply hole. The plug is used to open or close the liquid supply hole. The bottom end of the lifting rod is provided with an abutment plate. The spring is sleeved on the outside of the lifting rod. The two ends of the spring elastically abut against the bottom surface of the water tank and the top surface of the abutment plate, respectively. The float is fixedly connected to one end of the lever. The other end of the lever is used to abut against the bottom surface of the abutment plate.

[0008] Furthermore, an abutment block is protruding from the top surface of the end of the lever away from the float, and the top surface of the abutment block is used to abut the bottom surface of the abutment plate.

[0009] Furthermore, a spray hood is installed at the spray hole, and the spray hood is tilted upward with a spray nozzle.

[0010] Furthermore, the front panel of the wall-mounted unit is equipped with a temperature and humidity detector, which is electrically connected to the controller and is used to detect the temperature and humidity of the environment.

[0011] Furthermore, a liquid filling hole is provided in the middle of the top cover, and a flip cover is rotatably connected to the liquid filling hole. The flip cover is used to open or close the liquid filling hole.

[0012] Furthermore, a control panel is embedded in the front panel of the wall-mounted unit casing, and the control panel is electrically connected to the controller.

[0013] This utility model also provides a plasma sterilization and deodorization device, including a hypochlorous acid solution preparation device, one or more water pumps, and multiple wall-mounted plasma sterilization and deodorization devices. The water tank of the wall-mounted plasma sterilization and deodorization device is connected to the outlet of the water pump via an outlet pipe, and the inlet of the water pump is connected to the mixing tank of the hypochlorous acid solution preparation device via an inlet pipe. The hypochlorous acid solution preparation device is used to prepare hypochlorous acid solution and store it in its mixing tank. The water pump is used to supply the hypochlorous acid solution in the mixing tank of the hypochlorous acid solution preparation device to the water tank of the wall-mounted plasma sterilization and deodorization device.

[0014] The beneficial effects of this utility model are as follows: In practical applications, the wall-mounted unit is hung on the wall, and disinfectant solutions such as hypochlorous acid solution are placed in the water tank. The liquid level control valve monitors the liquid level in the atomizing box. When the liquid level in the atomizing box is lower than the target liquid level, the liquid level control valve opens the supply hole, and the hypochlorous acid solution in the water tank flows into the atomizing box through the supply hole. When the liquid level control valve detects that the liquid level in the atomizing box is equal to the target liquid level, the liquid level control valve closes the supply hole. The atomizing mechanism atomizes the hypochlorous acid solution in the atomizing box, and the hypochlorous acid mist flows along the atomizing channel. At the same time, the plasma generator generates plasma, and the fan drives the air in the environment to enter the fan through the air inlet. The fan drives the plasma airflow to flow along the air channel and converges with the hypochlorous acid mist to form a plasma hypochlorous acid atomized airflow, which then flows along the blow-out channel. Finally, the plasma hypochlorous acid atomized airflow is blown out from the spray hole. This invention utilizes the coordinated operation of a fan, a plasma generator, and an atomizing mechanism to create a plasma-hypochlorous acid atomized airflow. This effectively extends the blowing distance of the plasma and hypochlorous acid mist, as well as the activity time of the plasma. The plasma, carried by the hypochlorous acid mist, can be blown to every corner of the space, resulting in excellent deodorization and sterilization effects, a wide coverage area, and expanded range of air purification applications. Furthermore, the liquid level control valve can automatically control the opening or closing of the liquid supply port to automatically control the supply of hypochlorous acid solution from the water tank to the atomizing box, thereby achieving automatic replenishment of the hypochlorous acid solution in the atomizing box.

Detailed Implementation To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figures 1 to 6As shown, this utility model provides a wall-mounted plasma sterilizer and deodorizer, which includes a wall-mounted housing 1, a controller 2, a water tank 3, a top cover 4, an atomizing mechanism 5, a liquid level control valve 6, an atomizing box 7, a fan 8, a plasma generator 9, and a mist outlet housing 10. The atomizing mechanism 5, the fan 8, and the plasma generator 9 are all electrically connected to the controller 2. The controller 2 is installed on the front side plate of the wall-mounted housing 1. The water tank 3 is embedded in the wall-mounted housing 1. The top cover 4 is installed on the top port of the wall-mounted housing 1 and covers the opening of the water tank 3. The atomizing box 7 is installed in the wall-mounted housing 1 and fitted over the water tank 3. The bottom wall of the water tank 3 has a liquid supply hole 11. The liquid level control valve 6 is installed in the atomizing box 7 and is used to open or close the liquid supply hole 11. The atomizing mechanism 5 is installed in the atomizing box 7. The bottom surface of the wall-mounted housing 1... Alternatively, an air inlet 12 may be provided on the rear side. A fan 8 is installed inside the wall-mounted unit housing 1, with the air inlet of the fan 8 corresponding to and communicating with the air inlet 12. A plasma generator 9 is located at the air inlet 12. An air outlet duct 13 is provided on the inner wall of the wall-mounted unit housing 1, with the bottom end of the air outlet duct 13 communicating with the air outlet of the fan 8. A mist outlet channel housing 10 is installed inside the wall-mounted unit housing 1, and the mist outlet channel housing 10 is provided with an air duct 14, an atomizing channel 15, and a blow-out channel 16. The top end of the air outlet duct 13 communicates with one end of the air duct 14, and the other end of the air duct 14 communicates with the top end of the atomizing channel 15. The atomizing channel 15 is located above the atomizing mechanism 5, and the bottom end of the blow-out channel 16 communicates with the top end of the atomizing channel 15. A spray hole 17 is provided on the top of the front side panel of the wall-mounted unit housing 1, and the top end of the blow-out channel 16 communicates with the spray hole 17. Specifically, the atomizing mechanism 5 can use an existing atomizing device, which will not be described in detail here.

[0024] In practical applications, the wall-mounted unit casing 1 is mounted on the wall, and disinfectant solutions such as hypochlorous acid solution are filled into the water tank 3. The liquid level control valve 6 monitors the liquid level in the atomizing box 7. When the liquid level in the atomizing box 7 is lower than the target liquid level, the liquid level control valve 6 opens the supply port 11, allowing the hypochlorous acid solution in the water tank 3 to flow into the atomizing box 7 through the supply port 11. When the liquid level control valve 6 detects that the liquid level in the atomizing box 7 is equal to the target liquid level, the liquid level control valve 6 closes. The liquid supply port 11 is closed; the atomizing mechanism 5 atomizes the hypochlorous acid solution in the atomizing box 7, and the hypochlorous acid mist flows along the atomizing channel 15. At the same time, the plasma generator 9 generates plasma, and the fan 8 drives the ambient air to enter the fan 8 through the air inlet 12. The fan 8 drives the plasma airflow along the air channel 14 and converges with the hypochlorous acid mist to form a plasma hypochlorous acid atomized airflow, which then flows along the outlet channel 16. Finally, the plasma hypochlorous acid atomized airflow is blown out from the spray hole 17. In addition, hypochlorous acid solution can be added to the water tank 3 by opening the top cover 4. This wall-mounted plasma sterilizer and deodorizer is used by hanging it against the wall. Through the coordinated operation of the fan 8, plasma generator 9, and atomizing mechanism 5, a plasma hypochlorous acid atomized airflow is formed, which effectively extends the blowing distance of plasma and hypochlorous acid mist and the activity time of plasma. The plasma can be blown to every corner of the space through hypochlorous acid mist as a carrier, resulting in good deodorization and sterilization effect, wide coverage area, and expanded range of environmental air purification. It has a wide range of applications. In addition, the liquid level control valve 6 can automatically control the opening or closing of the liquid supply hole 11 to realize the automatic control of the supply of hypochlorous acid solution in the water tank 3 to the atomizing box 7, thereby realizing the automatic replenishment of hypochlorous acid solution in the atomizing box 7.

[0025] Furthermore, according to Bernoulli's principle, due to the high velocity and low pressure of the plasma airflow within duct 14, hypochlorous acid mist will be drawn into the plasma airflow to form a plasma hypochlorous acid atomized airflow. The airflow generated by fan 8 also serves to dissipate heat from the plasma generator 9.

[0026] In this embodiment, the rear panel of the wall-mounted unit housing 1 is provided with a wall-mounting slot 18. The housing 1 is mounted on a wall-mounting device by means of the wall-mounting slot 18.

[0027] In this embodiment, a filter screen 19 is installed on the bottom wall of the water tank 3, covering the top of the liquid supply hole 11. The filter screen 19 can filter disinfectant solutions such as hypochlorous acid solution in the water tank 3, preventing foreign objects from clogging the liquid level control valve 6.

[0028] In this embodiment, the liquid level control valve 6 includes a hinge seat 20, a plug 21, a lifting rod 22, a spring 23, a lever 24, and a float 25. The hinge seat 20 is installed on the inner bottom wall of the atomizing box 7. The middle part of the lever 24 is hinged to the hinge seat 20. The lifting rod 22 slides through the liquid supply hole 11. The plug 21 is installed on the top of the lifting rod 22 and is raised and lowered above the liquid supply hole 11. The plug 21 is used to open or close the liquid supply hole 11. The bottom end of the lifting rod 22 is provided with an abutment plate 26. The spring 23 is sleeved on the outside of the lifting rod 22. The two ends of the spring 23 elastically abut against the bottom surface of the water tank 3 and the top surface of the abutment plate 26, respectively. The float 25 is fixedly connected to one end of the lever 24. The other end of the lever 24 is used to abut against the bottom surface of the abutment plate 26. Specifically, the float 25 is a float bottle, and the weight of the float 25 is greater than the elastic force of the spring 23.

[0029] In practical applications, when the hypochlorous acid solution in the atomizing box 7 reaches the target level, the solution will cause the float 25 to rise. The rising float 25 will cause one end of the lever 24 to tilt upwards, while the end of the lever 24 near the contact plate 26 will swing downwards. The spring 23 will extend elastically and contact the contact plate 26, causing the lifting rod 22 and the plug 21 to slide downwards until the plug 21 closes the supply port 11. As the amount of hypochlorous acid solution in the atomizing box 7 gradually decreases, the solution level gradually drops. During this process, the float 25 will descend. Body 25 will cause one end of lever 24 to swing downward, causing the end of lever 24 near the contact plate 26 to tilt upward and touch the contact plate 26. This causes the contact plate 26, along with the lifting rod 22 and the plug 21, to move upward, thereby causing the plug 21 to gradually open the liquid supply hole 11. As the liquid supply hole 11 is opened, the hypochlorous acid solution in the water tank 3 will flow into the atomizing box 7 through the liquid supply hole 11 to achieve automatic replenishment of the hypochlorous acid solution in the atomizing box 7 until the liquid level of the hypochlorous acid solution in the atomizing box 7 reaches the target liquid level. Then, the plug 21 will close the liquid supply hole 11 and stop replenishing the liquid into the atomizing box 7.

[0030] Specifically, a counterweight 36 is rolled inside the float bottle. The counterweight 36 is preferably a counterweight ball. The counterweight ball rolls adaptively according to the tilt direction of the float bottle to ensure the working stability of the liquid level control valve 6.

[0031] In this embodiment, an abutment block 27 protrudes from the top surface of the end of the lever 24 away from the float 25. The top surface of the abutment block 27 is used to abut the bottom surface of the abutment plate 26. By adding the abutment block 27, the float 25 can be lowered by a relatively small amount to drive the lifting rod 22 and the plug 21 to move upward.

[0032] Specifically, the abutment block 27 can be made of an elastic material, such as a rubber block. This structural design avoids hard impact collisions between the abutment block 27 and the abutment plate 26, thus reducing noise.

[0033] In this embodiment, a spray hood 28 is installed at the spray hole 17, and a spray nozzle 29 is inclined upward on the spray hood 28. The spray nozzle 29 sprays the plasma hypochlorous acid atomized gas stream in a directional manner, which is beneficial to spray the plasma hypochlorous acid atomized gas stream to the designated area and improve the deodorization and sterilization effect.

[0034] In this embodiment, a temperature and humidity detector 30 is installed on the front panel of the wall-mounted unit casing 1. The temperature and humidity detector 30 is electrically connected to the controller 2 and is used to detect the temperature and humidity of the environment. Specifically, the temperature and humidity detector 30 can be a temperature and humidity measuring instrument. In practical applications, the temperature and humidity detector 30 detects the temperature and humidity of the environment in real time. When the ambient humidity is greater than the preset humidity value, the temperature and humidity detector 30 sends a signal to the controller 2, causing the controller 2 to control the atomizing mechanism 5 to stop atomizing or adjust the atomizing mechanism 5 to intermittent atomizing to ensure that the humidity in the indoor environment is kept within a constant range, avoiding excessive humidity and ensuring good comfort. During this process, the fan 8 continuously blows plasma into the environment.

[0035] Of course, other disinfectants can also be placed in water tank 3.

[0036] In this embodiment, a liquid filling hole is provided in the middle of the top cover 4, and a flip cover 31 is rotatably connected to the liquid filling hole. The flip cover 31 is used to open or close the liquid filling hole. When it is necessary to add hypochlorous acid solution to the water tank 3, simply lift the flip cover 31 to add hypochlorous acid solution to the water tank 3 through the liquid filling hole, without having to open the entire top cover 4.

[0037] In this embodiment, a control panel 37 is embedded in the front panel of the wall-mounted unit housing 1, and the control panel 37 is electrically connected to the controller 2. The control panel 37 facilitates the regulation of the working status of this utility model, such as adjusting the start-up time and the target humidity range in the room.

[0038] like Figure 7As shown, this utility model also provides a plasma sterilization and deodorization device, including a hypochlorous acid solution preparation device 32, one or more water pumps 33, and multiple wall-mounted plasma sterilization and deodorization devices. The water tank 3 of the wall-mounted plasma sterilization and deodorization device is connected to the outlet of the water pump 33 via a water outlet pipe 34. When there are multiple water pumps 33, each water pump 33 is respectively set to correspond to multiple wall-mounted plasma sterilization and deodorization devices. The water inlet of the water pump 33 is connected to the mixing tank of the hypochlorous acid solution preparation device 32 via a water inlet pipe 35. The hypochlorous acid solution preparation device 32 is used to prepare hypochlorous acid solution and store it in its mixing tank. The water pump 33 is used to supply the hypochlorous acid solution in the mixing tank of the hypochlorous acid solution preparation device 32 to the water tank 3 of the wall-mounted plasma sterilization and deodorization device. In practical applications, the hypochlorous acid solution preparation device 32 automatically prepares a hypochlorous acid solution of appropriate concentration and automatically supplies it to the water tank 3 of the wall-mounted plasma sterilizer and deodorizer via the water pump 33, thereby achieving automated replenishment of the water tank 3. This plasma sterilization and deodorization equipment enables one hypochlorous acid solution preparation device 32 to automatically supply hypochlorous acid solution to multiple wall-mounted plasma sterilizers and deodorizers.

[0039] Specifically, each water tank 3 of the wall-mounted plasma sterilizer and deodorizer is equipped with a low-level sensor and a high-level sensor. The low-level sensor is located at the bottom of the water tank 3, and the high-level sensor is located at the top of the water tank 3. Both the low-level and high-level sensors are electrically connected to their respective water pumps 33. In practical applications, when adding hypochlorous acid solution to the water tank 3, if the high-level sensor is triggered by the hypochlorous acid solution, it indicates that the water tank 3 is full of hypochlorous acid solution. The high-level sensor will then send a feedback message to the corresponding water pump 33, causing the water pump 33 to stop working. If the low-level sensor does not detect hypochlorous acid solution, it indicates that the hypochlorous acid solution in the water tank 3 is insufficient. The low-level sensor will then send a feedback signal to the corresponding water pump 33, causing the water pump 33 to start and pump solution to replenish the hypochlorous acid solution in the water tank 3.

[0040] Of course, a float module can also be used to control the water level in the water tank 3, replenish the liquid at any time to keep the water tank 3 full, and use the pipeline pressure to release the pressure to start the water pump 33, so that the hypochlorous acid solution from the hypochlorous acid solution preparation device 32 is supplied to the water tank 3.

[0041] This plasma sterilization and deodorization equipment possesses all the beneficial effects of a wall-mounted plasma sterilization and deodorization device, which will not be elaborated upon here.

[0042] Specifically, an air filter 38 is detachably installed at the air inlet 12. The air filter 38 filters the air entering the fan 8 to prevent foreign objects from entering the fan 8 through the air and causing the fan 8 to be easily damaged.

[0043] Specifically, the hypochlorous acid solution preparation device 32 is prior art, and can be found in the Chinese patent application document with application number 202321379234.2 filed by the applicant.

[0044] The synergy between hypochlorous acid atomization and plasma achieves more thorough sterilization, longer-lasting deodorization, and a wider range of applicable scenarios, making it especially suitable for environments with extremely high hygiene requirements, such as medical facilities (operating rooms, ICUs) and pet hospitals.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
