Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to a desktop plasma sterilization atomizer. Background Technology

[0002] Among existing patents, Chinese patent application number 202022704846.7 discloses a multi-stage energy-concentrating ring ultrasonic atomizing appliance, including a water tank. Inside the water tank are installed ultrasonic atomizing plates capable of generating high-frequency resonance, energy-concentrating rings for amplifying the high-frequency resonance, and a fan for blowing out water mist. It also includes a detachable mist outlet cover assembly mounted on the water tank. The energy-concentrating rings are installed inside an energy-concentrating ring conduit, and there are several energy-concentrating rings, with at least one energy-concentrating ring's central axis coinciding with the central axis of the energy-concentrating ring conduit. This patent only serves the function of atomization and humidification.

[0003] Furthermore, the applicant filed a Chinese patent application on March 11, 2024, with application number 202420471926.8, disclosing a sterilizing humidifier, which includes a water tank, an atomizing box, an atomizing component, a control component, and an ultraviolet sterilization component. The atomizing box is installed on top of the water tank and has a sealed cavity and an atomizing cavity inside. The sealed cavity is located below the atomizing cavity and is connected to the atomizing cavity through several through holes. The top of the atomizing box has a mist outlet that communicates with the atomizing cavity. The control component is located inside the sealed cavity. The atomizing component includes several vibrating plates, which are located at each through hole and seal the through holes. Each vibrating plate is electrically connected to the control component. The ultraviolet sterilization component is located inside the atomizing cavity. The atomizing box also has a water suction pipe, both ends of which are connected to the inner cavity of the water tank and the atomizing cavity, with one end higher than the bottom wall of the atomizing cavity. The water tank has a water pump connected to the water suction pipe. While the patent document achieves atomized humidification and sterilization, the distance the mist travels is short, the coverage area is small, and the sterilization effect is unsatisfactory. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a desktop plasma sterilization atomizer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A desktop plasma sterilization atomizer includes a controller, a housing, a cover, a spray cap, a mist guide tube, an atomizing device, a fan, a plasma generator, an air guide tube, and a converging mist hood. The fan and atomizing device are electrically connected to the controller. The cover is installed at the top port of the housing, with a through hole in the center. The spray cap is installed at the through hole. The bottom wall of the housing's inner cavity has a partition plate and an air inlet. The partition plate divides the inner cavity of the housing into a blowing chamber and an atomizing chamber. The blowing chamber communicates with the air inlet. The fan is installed on the bottom wall of the housing and located within the blowing chamber, with its air inlet communicating with the air inlet. The converging mist hood includes an air guide channel, a converging chamber communicating with the air guide channel, and a surrounding mist hood. The outer periphery is provided with a diffusion cone orifice and a mist outlet is opened on the side wall of the converging cavity. The converging cavity arches upward into the diffusion cone orifice. The diffusion cone orifice is set directly opposite the spray cap. The diffusion cone orifice is connected to the converging cavity through the mist outlet. The bottom end of the air guide pipe is connected to the air outlet of the fan. The top end of the air guide pipe is connected to one end of the air guide channel. The other end of the air guide channel is connected to the converging cavity. The mist guide pipe is installed on the inner wall of the housing. The top end of the mist guide pipe is connected to the converging cavity. The atomizing device is installed at the bottom end of the mist guide pipe. The atomizing device is located in the atomizing cavity. The atomizing cavity is used to store hypochlorous acid disinfectant. The atomizing device is used to atomize the hypochlorous acid disinfectant in the atomizing cavity. The plasma generator is installed at the air inlet.

[0007] Furthermore, a rotating ring is provided at the through hole, and the spray cover is rotatably connected to the rotating ring, with a spray hole opened on the spray cover.

[0008] Furthermore, the desktop plasma sterilization atomizer also includes a temperature and humidity detector embedded in the outer wall of the housing. The temperature and humidity detector is electrically connected to the controller and is used to detect the temperature and humidity of the environment.

[0009] Furthermore, a control panel is installed on the outer wall of the housing, and the control panel is electrically connected to the controller.

[0010] Furthermore, the plasma generator is mounted on the air inlet via an insulating component.

[0011] Furthermore, a filter screen is detachably installed on the bottom surface of the housing, and the filter screen covers the air inlet end of the air inlet hole.

[0012] Furthermore, a high liquid level sensor and a low liquid level sensor are installed inside the housing. Both the high liquid level sensor and the low liquid level sensor are located inside the atomization chamber. The high liquid level sensor is used to detect the highest liquid level in the atomization chamber, and the low liquid level sensor is used to detect the lowest liquid level in the atomization chamber.

[0013] Furthermore, a drain hole is provided on the bottom surface of the housing, which is connected to the atomization chamber, and a sealing plug is detachably connected to the drain hole.

[0014] Furthermore, the bottom surface of the casing is equipped with multiple support feet.

[0015] The beneficial effects of this invention are as follows: In practical applications, hypochlorous acid disinfectant is loaded into the atomizing chamber, and the atomizing device atomizes the hypochlorous acid disinfectant in the atomizing chamber to form hypochlorous acid mist. The hypochlorous acid mist enters the converging chamber along the mist guide tube. At the same time, the plasma generator and the fan are started. The plasma generator produces plasma, and the fan blows the gas in the environment along with the plasma into the air guide tube to form a plasma airflow. The plasma airflow enters the converging chamber and merges with the hypochlorous acid mist. The plasma airflow blows the hypochlorous acid mist outward. Under the action of the airflow, the plasma and hypochlorous acid mist enter the diffusion cone orifice and are sprayed out from the spray cap, which increases the distance that the hypochlorous acid mist and plasma are blown out and the coverage area is wide. The hypochlorous acid mist acts as a transport carrier for the plasma, prolonging the activity time of the plasma. In this process, the hypochlorous acid mist is used to deodorize and sterilize the environment and maintain the humidity of the air. The strong oxidizing properties of the plasma are used to decompose pollutants in the air (such as VOCs, bacteria, etc.). The fan also serves to dissipate heat from the plasma generator. Additionally, excess hypochlorous acid mist forms hypochlorous acid droplets on the outer wall of the collecting chamber and then flows back to the atomizing chamber through the mist guide pipe. This invention, through the coordinated operation of the fan, plasma generator, and atomizing device, forms a plasma-hypochlorous acid atomized airflow, effectively extending the blowing distance of the plasma and hypochlorous acid mist and the activity time of the plasma. This results in excellent deodorization and sterilization effects, a wide coverage area, and expands the scope of environmental air purification, making it widely applicable.

[0021] 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.

[0022] like Figures 1 to 3 As shown, this utility model provides a desktop plasma sterilization atomizer, which includes a controller 1, a housing 2, a cover 3, a spray cover 4, a mist guide tube 5, an atomizing device 6, a fan 7, a plasma generator 8, an air guide tube 9, and a converging mist hood 10. The fan 7 and the atomizing device 6 are both electrically connected to the controller 1. The cover 3 is installed at the top port of the housing 2, and a through hole 11 is opened in the middle of the cover 3. The spray cover 4 is installed at the through hole 11. The inner cavity bottom wall of housing 2 is provided with a partition plate 12 and an air inlet 13. The partition plate 12 divides the inner cavity of housing 2 into a blowing chamber 14 and an atomizing chamber 15. The blowing chamber 14 is connected to the air inlet 13. The fan 7 is installed on the bottom wall of housing 2 and located in the blowing chamber 14. The air inlet of the fan 7 is connected to the air inlet 13. The converging mist hood 10 is provided with an air guide channel 16, a converging chamber 17 connected to the air guide channel 16, and a surrounding periphery of the converging chamber 17. The diffuser cone 18 and the mist outlet 19 are located on the side wall of the converging cavity 17. The converging cavity 17 arches upward into the diffuser cone 18. The diffuser cone 18 is positioned opposite the spray cap 4. The diffuser cone 18 is connected to the converging cavity 17 via the mist outlet 19. The bottom end of the air duct 9 is connected to the air outlet of the fan 7. The top end of the air duct 9 is connected to one end of the air duct channel 16. The other end of the air duct channel 16 is connected to the converging cavity 17. The mist guide tube 5 is installed on the inner wall of the housing 2. The top end of the mist guide tube 5 is connected to the converging cavity 17. The atomizing device 6 is installed at the bottom end of the mist guide tube 5. The atomizing device 6 is located in the atomizing cavity 15. The atomizing cavity 15 is used to store hypochlorous acid disinfectant. The atomizing device 6 is used to atomize the hypochlorous acid disinfectant in the atomizing cavity 15. The plasma generator 8 is installed at the air inlet 13. Specifically, the atomizing device 6 adopts the existing atomizing mechanism, which will not be described in detail here.

[0023] In practical applications, hypochlorous acid disinfectant is loaded into the atomizing chamber 15. The atomizing device 6 atomizes the hypochlorous acid disinfectant in the atomizing chamber 15 to form hypochlorous acid mist. The hypochlorous acid mist enters the converging chamber 17 along the mist guide tube 5. At the same time, the plasma generator 8 and the fan 7 are started. The plasma generator 8 generates plasma, and the fan 7 blows the gas in the environment along with the plasma into the air guide tube 9 to form a plasma airflow. The plasma airflow enters the converging chamber 17 and merges with the hypochlorous acid mist, thus forming a plasma flow. The airflow blows hypochlorous acid mist outwards. Under the influence of the airflow, both plasma and hypochlorous acid mist enter the diffusion cone orifice 18 and are ejected from the spray cap 4. This increases the distance the hypochlorous acid mist and plasma travel, resulting in a wider coverage area. The hypochlorous acid mist acts as a transport carrier for the plasma, extending its activity time. During this process, the hypochlorous acid mist deodorizes and sterilizes the environment and maintains air humidity, while the strong oxidizing properties of the plasma decompose airborne pollutants (such as VOCs and bacteria). The fan 7 also serves to dissipate heat from the plasma generator 8. Furthermore, excess hypochlorous acid mist forms hypochlorous acid droplets on the outer wall of the collecting chamber 17 and then flows back to the atomizing chamber 15 through the mist guide pipe 5. This invention utilizes the coordinated operation of a fan 7, a plasma generator 8, and an atomizing device 6 to form 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 good and long-lasting deodorization and sterilization effects, a wide coverage area, and an expanded range of applications for purifying ambient air.

[0024] In this embodiment, a rotating ring 20 is provided at the through hole 11, and the spray cover 4 is rotatably connected to the rotating ring 20. The spray cover 4 has a spray hole 21. In practical applications, the plasma hypochlorous acid atomized gas flow is sprayed out through the spray hole 21; in addition, by driving the spray cover 4 to rotate relative to the rotating ring 20, the angle and orientation of the spray cover 4 can be changed, so that the plasma hypochlorous acid atomized gas flow can be sprayed to the designated area, further improving the deodorizing and sterilizing effect.

[0025] In this embodiment, the desktop plasma sterilization atomizer also includes a temperature and humidity detector 22 embedded in the outer wall of the housing 2. The temperature and humidity detector 22 is electrically connected to the controller 1 and is used to detect the temperature and humidity of the environment. In practical applications, the temperature and humidity detector 22 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 22 sends a signal to the controller 1, causing the controller 1 to control the atomizing device 6 to stop atomizing or adjust the atomizing device 6 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 7 continuously blows plasma into the environment to continue the sterilization and deodorization effect.

[0026] In this embodiment, a control panel 23 is installed on the outer wall of the housing 2, and the control panel 23 is electrically connected to the controller 1. The control panel 23 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.

[0027] In this embodiment, the plasma generator 8 is mounted on the air inlet 13 via an insulating component 24. The insulating component 24 is locked to the air inlet of the housing 2 or the fan 7 by bolts. This structural design facilitates the assembly and disassembly of the plasma generator 8 and also serves as insulation.

[0028] In this embodiment, a filter screen 25 is detachably installed on the bottom surface of the housing 2, and the filter screen 25 covers the air inlet end of the air inlet hole 13. The filter screen 25 can filter the air entering the fan 7 to prevent impurities and other foreign objects from entering the fan 7 and causing damage to the fan 7.

[0029] Specifically, cotton pads are installed at filter 25 to absorb perfume, and the fragrance is sent out by fan 7, achieving the effect of odor fumes.

[0030] In this embodiment, a high-level sensor and a low-level sensor are installed inside the housing 2. Both sensors are located within the atomizing chamber 15. The high-level sensor detects the highest liquid level in the atomizing chamber 15, and the low-level sensor detects the lowest liquid level. In practical applications, when adding hypochlorous acid disinfectant to the atomizing chamber 15, if the high-level sensor detects that the chamber is full, it sends a signal to the controller 1, causing the control panel 23 to display that the liquid level is within the acceptable range and sound an alarm to remind the operator to stop adding the disinfectant. Conversely, if the low-level sensor does not detect any disinfectant, it indicates that the chamber is low. The low-level sensor sends a signal to the controller 1, causing the control panel 23 to display that the liquid level is insufficient. At this point, atomization stops to prevent overheating and damage to the atomizing device 6, and an alarm sounds to remind the operator to add more disinfectant.

[0031] In this embodiment, a drain hole 26 is provided on the bottom surface of the housing 2. The drain hole 26 is connected to the atomizing chamber 15, and a sealing plug is detachably connected to the drain hole 26. When it is necessary to replace or clean the atomizing chamber 15, the sealing plug is opened, and the residual hypochlorous acid disinfectant is poured out through the drain hole 26. Then, clean water is introduced into the atomizing chamber 15 to clean it. The cleaned water is discharged through the drain hole 26.

[0032] In this embodiment, the bottom surface of the housing 2 is provided with multiple support feet 27. The multiple support feet 27 support the housing 2, so that there is a ventilation space between the bottom surface of the housing 2 and the supporting surface (such as a tabletop), which is conducive to air entering the fan 7 from the air inlet 13.

[0033] 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.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] 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.
