[0002] Sterilizers and deodorizers are widely used in refrigerators, cars, kitchens, bathrooms, and hospitals, primarily for air purification and sterilization in relatively confined spaces. Existing deodorizers are typically manually activated or controlled from a distance using a remote control, and cannot be operated remotely, which is inconvenient. Furthermore, most existing deodorizers sterilize and remove odors by generating ozone and releasing it into the air with a fan. However, in confined spaces, ozone at certain concentrations can be harmful to human health. Temporary entry into such an environment requires turning off the deodorizer and waiting for the ozone to decompose and reduce to a safe concentration before entering. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 and Figure 2As shown, an embodiment of the present invention provides a safe and efficient sterilization and deodorization system, including a deodorizer 1, a cloud platform 2, and a mobile terminal 3. The deodorizer 1 includes a barrel 10, with an air outlet 101 provided at the top of the barrel 10, a fan 102 installed at the air outlet 101, an air inlet 103 circumferentially formed at the bottom of the barrel 10, and an air intake grille 104 provided at the air inlet 103. A first detection sensor 108, a sterilization unit 105, and a microcontroller 106 are provided within the barrel 10, and an odor sensor 107 is installed outside the barrel 10. The first detection sensor 108 is used to monitor the concentration of active radicals within the barrel 10, and the odor sensor 107 is used to monitor the concentration of TVOC and formaldehyde in the environment. When the TVOC and formaldehyde concentrations reach preset values, the microcontroller 106 can automatically activate the sterilization unit 105 to start operation. The sterilization unit 105 is used to generate active radicals. Among them, fan 102, first detection sensor 108, sterilization unit 105, and odor sensor 107 are all electrically connected to microcontroller 106. Microcontroller 106 and mobile terminal 3 are both connected to cloud platform 2 via wireless modules. In this embodiment, cloud platform 2 is the Alibaba Cloud platform, and the wireless module of deodorizer 1 is an Internet of Things wireless module. Specifically, during use, the concentration data monitored by odor sensor 107 and the power data of active radicals generated by sterilization unit 105 are uploaded to the Alibaba Cloud platform via the Internet of Things wireless module. Users can view them online on mobile terminal 3. At the same time, mobile terminal 3 can also be used to remotely control deodorizer 1 and adjust the concentration of active radicals.

[0022] In this embodiment, a buffer chamber 109 is provided at the bottom of the cylinder 10; when the concentration of active groups monitored by the first detection sensor 108 is less than the equilibrium threshold, the microcontroller 106 controls the fan 102 to be turned off, and the generated active groups sink and gather in the buffer chamber 109; when the concentration of active groups monitored by the first detection sensor 108 is greater than the equilibrium threshold, the microcontroller 106 controls the fan 102 to start and blow out the gathered active groups. According to this arrangement, intermittent discharge of active groups can be achieved, so that the concentration of active groups in the environment will not remain too high. During the process of gathering active groups, the active groups in the environment gradually degrade. When the concentration of active groups is reduced to a safe concentration, the user can enter and exit safely. Therefore, this technology can provide the environment with an intermittent safe concentration of active groups, thereby facilitating temporary entry and exit of users.

[0023] Based on the above embodiment, an indicator light 1010 and a second detection sensor 1018 are also installed on the outside of the cylinder 10, and the indicator light 1010 and the second detection sensor 1018 are electrically connected to the microcontroller 106; when the concentration of the active group monitored by the second detection sensor 1018 is greater than the safety concentration threshold, the microcontroller 106 controls the indicator light 1010 to turn on and remind the user, thereby facilitating the user to identify the safe concentration of the active group.

[0024] Furthermore, the sterilization unit 105 uses a VUV ultraviolet lamp.

[0025] Specifically, the upper portion of the inner wall of the cylinder 10 is connected to a first base plate 1012 via a bracket 1011. An air passage is formed between the cylinder 10 and the first base plate 1012. The fan 102 is mounted on the upper surface of the first base plate 1012, and the VUV ultraviolet lamp is mounted on the lower surface of the first base plate 1012. An annular partition 1013 is provided on the inner wall of the cylinder 10 at the upper edge of the air inlet 103. The partition 1013 divides the inner cavity of the cylinder 10 into a sterilization chamber 1016 and a purification chamber 1017. The sterilization chamber 1016 and the purification chamber 1017 are arranged in an upper and lower direction. The first detection sensor 108 and the VUV ultraviolet lamp are disposed in the sterilization chamber 1016. A purification filter cartridge (not shown in the figure) is installed in the purification chamber 1017, and the purification filter cartridge is disposed on the air intake grille 104. The bottom surface of the partition 1013 is connected to a first positioning plate 1014 for fitting onto the top of the purification filter cartridge. The bottom of the cylinder 10 is detachably connected to a base 11. The upper edge of the base 11 is connected to a second annular bottom plate 110. The top surface of the second bottom plate 110 is connected to a second positioning plate 111 for fitting onto the bottom of the purification filter cartridge. It should be noted that the partition 1013 and the second bottom plate 110 can respectively block the upper and lower end faces of the purification filter cartridge, so that when the ambient air enters the cylinder 10, it is first filtered and purified by the purification filter cartridge, and then illuminated by a VUV ultraviolet lamp to generate active groups, thereby utilizing the active groups to decompose TVOC and formaldehyde. The base 11 and the cylinder 10 can be installed and connected by a threaded connection, and after removing the base 11, it is convenient to replace the purification filter cartridge.

[0026] Based on the above embodiment, a vertically distributed and cylindrical baffle 1015 is connected to the bottom surface of the partition 1013 and is located within the first positioning plate 1014. An air inlet channel is formed between the baffle 1015 and the inner wall of the purification filter cartridge, and between the baffle 1015 and the second bottom plate 110. The inner cavity of the baffle 1015 and the inner cavity of the base 11 together form a buffer cavity 109. When the purification filter cartridge uses activated carbon for deodorization, adsorption and filtration, since the activated carbon can decompose the active groups, the two cannot be in direct contact, otherwise it will affect the aggregation of the active groups generated in the cartridge body 10. The provision of the baffle 1015 can separate the generated active groups from the purification filter cartridge, thereby improving the stability and timeliness of the active groups when they are aggregated and stored.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
