[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of those different embodiments or examples, without contradiction.

[0026] Because refrigerators store a variety of foods, and people often neglect hygiene within the storage space, refrigerators are prone to bacterial growth and unpleasant odors. Related technologies typically employ photocatalytic sterilization. However, the photosensitive semiconductor materials used in photocatalytic sterilization have a wide bandwidth and can only absorb ultraviolet light to generate sterilizing and deodorizing substances, failing to absorb longer wavelengths of visible light, thus resulting in poor sterilization effectiveness.

[0027] To address the aforementioned problems, this application provides a sterilization and deodorization device. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 , Figure 1 This is a front view of the sterilization and deodorization device provided in the embodiments of this application. Figure 2 This is a top view of the sterilization and deodorization device provided in the embodiments of this application. The sterilization and deodorization device 100 may include a housing 101, a water reservoir 102, an ultrasonic module 103, and a catalytic module 104.

[0028] The water reservoir 102 can be housed within the housing 101. Specifically, the water reservoir 102 can be detachably and fixedly connected to the housing 101. When the water reservoir 102 is connected to the housing 101, it is located inside the housing 101. Since the water reservoir 102 is used for water storage, when there is no water in the water reservoir 102 or the water level in the water reservoir 102 is below the minimum water level line, the water reservoir 102 can be removed from the housing 101 for refilling. After refilling, it can be reconnected to the housing 101. The connection method between the water reservoir 102 and the housing 101 can be a bayonet or threaded rotation method, etc., and is not specifically limited here. The water reservoir 102 can be a water box, water bucket, etc.

[0029] The ultrasonic module 103 can be installed inside the water reservoir 102. Since the water reservoir 102 contains water, if the ultrasonic module 103 is installed inside the water reservoir 102, it must be waterproof. The ultrasonic module 103 can be used to emit ultrasonic waves, so that the ultrasonic waves act on the water in the water reservoir 102 to produce light of different wavelengths. Specifically, the ultrasonic module 103 may include an ultrasonic transducer, which can convert electrical signals into ultrasonic signals and emit them.

[0030] The catalytic module 104 can be disposed around the periphery of the water reservoir 102. Specifically, if the water reservoir 102 is a cylindrical water reservoir, the catalytic module 104 can be disposed around its circular periphery; if the water reservoir 102 is a cuboid or cube-shaped water reservoir, the catalytic module 104 can be disposed on the four sides of its cross-section. The catalytic module 104 can absorb light of different wavelengths that passes through the water reservoir 102 to generate bactericidal and deodorizing substances. By absorbing light of different wavelengths, the catalytic module 104 can trigger a photocatalytic reaction to generate bactericidal and deodorizing substances, thereby improving the bactericidal and deodorizing effect.

[0031] It should be noted that, since the ultrasonic module 103 is installed inside the water storage tank 102, the ultrasonic waves emitted by the ultrasonic module 103 will act on the water in the water storage tank 102 to cause cavitation effect, that is, the cavities in the water migrate. The movement of the cavities will cause the water to vibrate, thereby generating bubbles. During the continuous vibration process, the bubbles will burst. It is equivalent to the bubbles being formed and bursting continuously. At the moment when the bubbles burst, light will be generated, including light of different wavelengths.

[0032] Light of different wavelengths can include both long-wavelength and short-wavelength light. Long-wavelength light includes visible light, such as red, orange, yellow, blue, cyan, and violet light. The wavelengths of red, orange, yellow, blue, cyan, and violet light decrease sequentially while their frequencies increase sequentially; that is, the wavelength of red light is greater than that of violet light, and the frequency of red light is less than that of violet light. Short-wavelength light includes invisible light, such as ultraviolet A, UVB, and UVC. UVA, UVB, and UVC have different wavelengths. Visible light has a longer wavelength than invisible light, and its frequency is less than that of invisible light.

[0033] In some embodiments, light of different wavelengths may include a first wavelength light and a second wavelength light, with longer wavelength light serving as the first wavelength light and shorter wavelength light serving as the second wavelength light. It should be noted that the catalytic module 104 may include a photosensitive semiconductor material and an upconversion agent. The photosensitive semiconductor material can absorb light and undergo a photocatalytic reaction to generate bactericidal and deodorizing substances. Specifically, the photosensitive semiconductor material, as a photocatalyst, possesses redox capabilities under the action of light absorption, thereby undergoing a photocatalytic reaction to generate free electrons and holes. Holes can react with water vapor in the air to generate hydroxyl radicals, while electrons can react with oxygen in the air to generate superoxide radicals and hydroxyl radicals. Both hydroxyl radicals and superoxide radicals have bactericidal and deodorizing effects; that is, the bactericidal and deodorizing substances generated by the photocatalytic reaction caused by the photosensitive semiconductor material absorbing light may include hydroxyl radicals and superoxide radicals.

[0034] It should also be noted that photosensitive semiconductor materials can only absorb short-wavelength light to undergo photocatalytic reactions, and do not absorb long-wavelength light. Therefore, the catalytic module 104 can also be used to absorb the first wavelength of light through the photosensitive semiconductor material to generate bactericidal and deodorizing substances, but cannot directly absorb the second wavelength of light.

[0035] For the second wavelength light, the wavelength can be converted by an upconversion agent disposed in the catalytic module 104. Specifically, the second wavelength light absorbed by the catalytic module 104 can act on the upconversion agent to undergo an upconversion luminescence reaction, thereby converting the second wavelength light into the first wavelength light. The converted first wavelength light can then be absorbed by a photosensitive semiconductor material to undergo a photocatalytic reaction and generate bactericidal and deodorizing substances. That is, the catalytic module 104 can also be used to convert the second wavelength light into the first wavelength light through the upconversion agent, and to absorb the first wavelength light through a photosensitive semiconductor material to generate bactericidal and deodorizing substances, such as hydroxyl radicals and superoxide radicals.

[0036] Among them, the photosensitive semiconductor material can include a mixture of vanadium bismuth tetroxide and molybdenum oxide. The band gap of vanadium bismuth tetroxide is 2.4 eV. Since the band gap of vanadium bismuth tetroxide is relatively narrow, it is beneficial to absorb more short-wavelength light. Molybdenum oxide or molybdenum-based materials can promote the transfer of holes generated in the photocatalytic reaction of the photosensitive semiconductor material, thereby improving the photocatalytic efficiency and thus improving the sterilization and deodorization effect.

[0037] The top-conversion agent may include a mixture of trivalent erbium ions and yttrium aluminate, and may also include other rare earth materials.

[0038] As can be seen from the above, through the sonoluminescence of the ultrasonic module 103 and the photocatalytic reaction of the catalytic module 104, bactericidal and deodorizing substances can be generated by light of different wavelengths. Compared with the fact that bactericidal and deodorizing substances can only be generated by light of specific wavelengths such as ultraviolet light, the waste of long wavelength light can be avoided and the bactericidal and deodorizing effect can be improved.

[0039] In some embodiments, after the ultrasonic module 103 emits ultrasonic waves and causes a cavitation effect with the water in the water reservoir 102, the cavitation causes the water to vibrate and generate bubbles. These bubbles continuously form and burst, resulting in localized high temperature and high pressure areas. These high temperature and high pressure areas can be called hot spots. These hot spots can undergo pyrolysis with the water in the water reservoir 102, i.e., the water decomposes upon heating, thereby generating hydroxyl radicals. Specifically, the ultrasonic waves emitted by the ultrasonic module 103 act on the water in the water reservoir 102, causing a pyrolysis reaction that generates bactericidal and deodorizing substances, including hydroxyl radicals.

[0040] It should be noted that since the ultrasonic module 103 is located inside the water reservoir 102, the ultrasonic waves generate hot spots through cavitation effects with the water. The pyrolysis of these hot spots with the water occurs within the water reservoir 102. Therefore, the generated bactericidal and deodorizing substances, i.e., hydroxyl radicals, need to be discharged from the water reservoir 102 and out of the bactericidal and deodorizing device 100 to achieve their bactericidal and deodorizing effects. Therefore, multiple openings can be provided on the side wall of the water reservoir 102, allowing the bactericidal and deodorizing substances to be discharged through these openings to the outside of the bactericidal and deodorizing device 100.

[0041] It is understandable that since the ultrasonic waves emitted by the ultrasonic module 103 act on the water in the water tank 102, different wavelengths of light are generated inside the water tank 102. If the different wavelengths of light are to be absorbed by the catalytic module 104, the water tank 102 needs to have light transmission capability, that is, the water tank 102 needs to be a light-transmitting material. The water tank 102 needs to be able to transmit light of different wavelengths, including long wavelengths and short wavelengths. For example, the water tank 102 can be made of transparent glass or other light-transmitting materials. The material of the water tank 102 is not specifically limited here.

[0042] It should be noted that the water storage tank 102, the ultrasonic module 103, and the catalytic module 104 are all located inside the housing 101. In order to allow the generated sterilizing and deodorizing substances to be discharged through the housing 101 to the outside of the sterilizing and deodorizing device 100, multiple through holes can be provided around the periphery of the housing 101. Thus, the sterilizing and deodorizing substances can be discharged from inside the housing 101 to the outside of the housing 101 through the multiple through holes, and sterilization and deodorization are achieved through the sterilizing and deodorizing substances.

[0043] In addition to the functions of photocatalysis by the acoustic luminescence and catalytic reaction of the catalytic module 104, and the generation of bactericidal and deodorizing substances by pyrolysis of the water in the water tank 102 through ultrasonic waves, the ultrasonic waves emitted by the ultrasonic module 103 can also atomize the water in the water tank 102 through high-frequency oscillation. The atomized water can be discharged to the outside of the bactericidal and deodorizing device 100 through the opening provided on the surface of the water tank 102, thereby achieving the function of atomization and humidification.

[0044] Specifically, ultrasound waves can break down the water in the water reservoir 102 into ultra-fine atomized particles through high-frequency oscillation. These ultra-fine atomized particles react with the water to form water mist, which can achieve the function of atomization and humidification. Furthermore, the generated water mist is cold mist, which also has a cooling effect and can improve the body's ability to absorb oxygen and expel carbon dioxide. In other words, the sterilization and deodorization device 100 not only has the function of sterilization and deodorization but also has the function of atomization and humidification.

[0045] It is understandable that since the atomized water is discharged through the opening of the water storage tank 102, and the bactericidal and deodorizing substance generated by the pyrolysis reaction between the ultrasonic waves and the water in the water storage tank 102 is also discharged through the opening of the water storage tank 102, the bactericidal and deodorizing substance and the atomized water can be discharged together from the opening to the bactericidal and deodorizing device, so that the bactericidal and deodorizing device 100 has three functions of bactericidal, deodorizing and humidifying at the same time.

[0046] As can be seen from the above, in this embodiment, the ultrasonic waves emitted by the ultrasonic module 103 act on the water in the water storage tank 102 to generate light of different wavelengths, and the light of different wavelengths can be absorbed by the catalytic module 104 to trigger a photocatalytic reaction to generate bactericidal and deodorizing substances, thereby improving the bactericidal and deodorizing effect.

[0047] Accordingly, this application also provides a sterilization and deodorization device, which may include the sterilization and deodorization device 100 as described in the above embodiment. The sterilization and deodorization device may include a refrigerator, air conditioner, air purifier, fresh air system, vacuum cleaner, dehumidifier, dryer, clothes dryer, or heater. For example, a refrigerator equipped with the sterilization and deodorization device 100 can remove bacteria and odors generated by food inside the refrigerator; an air purifier equipped with the sterilization and deodorization device 100 can remove bacteria and odors from the air.

[0048] The following example uses a refrigerator as an example of a sterilization and deodorization device. Because refrigerators store a variety of foods, people often neglect the hygiene of the food storage space, leading to unpleasant odors due to bacterial growth. This problem can be solved by installing a sterilization and deodorization device 100 inside the refrigerator. Please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. The refrigerator 200 may include a refrigerator body 201 and a sterilization and deodorization device 100.

[0049] The refrigerator body 201 can be the outer shell of the refrigerator 200. The refrigerator body 201 can include at least one compartment, such as a refrigerator compartment and / or a freezer compartment. Users usually store various foods in the refrigerator compartment, which can easily lead to bacterial growth over time. Therefore, the sterilization and deodorization device 100 can be installed inside the refrigerator body 201. Specifically, the sterilization and deodorization device 100 can be installed in the refrigerator compartment. Of course, it can also be installed in the freezer compartment, or separately in the refrigerator compartment and the freezer compartment.

[0050] Please continue reading. Figure 1 and Figure 2 The sterilization and deodorization device 100 may include a housing 101, a water tank 102, an ultrasonic module 103, and a catalytic module 104.

[0051] The water reservoir 102 can be housed within the housing 101. Specifically, the water reservoir 102 can be detachably and fixedly connected to the housing 101. When the water reservoir 102 is connected to the housing 101, it is located inside the housing 101. Since the water reservoir 102 is used for water storage, when there is no water in the water reservoir 102 or the water level in the water reservoir 102 is below the minimum water level line, the water reservoir 102 can be removed from the housing 101 for refilling. After refilling, it can be reconnected to the housing 101. The connection method between the water reservoir 102 and the housing 101 can be a bayonet or threaded rotation method, etc., and is not specifically limited here. The water reservoir 102 can be a water box, water bucket, etc.

[0052] The ultrasonic module 103 can be installed inside the water reservoir 102. Since the water reservoir 102 contains water, if the ultrasonic module 103 is installed inside the water reservoir 102, it must be waterproof. The ultrasonic module 103 can be used to emit ultrasonic waves, so that the ultrasonic waves act on the water in the water reservoir 102 to produce light of different wavelengths. Specifically, the ultrasonic module 103 may include an ultrasonic transducer, which can convert electrical signals into ultrasonic signals and emit them.

[0053] The catalytic module 104 can be disposed around the periphery of the water reservoir 102. Specifically, if the water reservoir 102 is a cylindrical water reservoir, the catalytic module 104 can be disposed around its circular periphery; if the water reservoir 102 is a cuboid or cube-shaped water reservoir, the catalytic module 104 can be disposed on the four sides of its cross-section. The catalytic module 104 can absorb light of different wavelengths that passes through the water reservoir 102 to generate bactericidal and deodorizing substances. By absorbing light of different wavelengths, the catalytic module 104 can trigger a photocatalytic reaction to generate bactericidal and deodorizing substances, thereby improving the bactericidal and deodorizing effect.

[0054] It should be noted that, since the ultrasonic module 103 is installed inside the water storage tank 102, the ultrasonic waves emitted by the ultrasonic module 103 will act on the water in the water storage tank 102 to cause cavitation effect, that is, the cavities in the water migrate. The movement of the cavities will cause the water to vibrate, thereby generating bubbles. During the continuous vibration process, the bubbles will burst. It is equivalent to the bubbles being formed and bursting continuously. At the moment when the bubbles burst, light will be generated, including light of different wavelengths.

[0055] Light of different wavelengths can include both long-wavelength and short-wavelength light. Long-wavelength light includes visible light, such as red, orange, yellow, blue, cyan, and violet light. The wavelengths of red, orange, yellow, blue, cyan, and violet light decrease sequentially while their frequencies increase sequentially; that is, the wavelength of red light is greater than that of violet light, and the frequency of red light is less than that of violet light. Short-wavelength light includes invisible light, such as ultraviolet A, UVB, and UVC. UVA, UVB, and UVC have different wavelengths. Visible light has a longer wavelength than invisible light, and its frequency is less than that of invisible light.

[0056] In some embodiments, light of different wavelengths may include a first wavelength light and a second wavelength light, with longer wavelength light serving as the first wavelength light and shorter wavelength light serving as the second wavelength light. It should be noted that the catalytic module 104 may include a photosensitive semiconductor material and an upconversion agent. The photosensitive semiconductor material can absorb light and undergo a photocatalytic reaction to generate bactericidal and deodorizing substances. Specifically, the photosensitive semiconductor material, as a photocatalyst, possesses redox capabilities under the action of light absorption, thereby undergoing a photocatalytic reaction to generate free electrons and holes. Holes can react with water vapor in the air to generate hydroxyl radicals, while electrons can react with oxygen in the air to generate superoxide radicals and hydroxyl radicals. Both hydroxyl radicals and superoxide radicals have bactericidal and deodorizing effects; that is, the bactericidal and deodorizing substances generated by the photocatalytic reaction caused by the photosensitive semiconductor material absorbing light may include hydroxyl radicals and superoxide radicals.

[0057] It should also be noted that photosensitive semiconductor materials can only absorb short-wavelength light to undergo photocatalytic reactions, and do not absorb long-wavelength light. Therefore, the catalytic module 104 can also be used to absorb the first wavelength of light through the photosensitive semiconductor material to generate bactericidal and deodorizing substances, but cannot directly absorb the second wavelength of light.

[0058] For the second wavelength light, the wavelength can be converted by an upconversion agent disposed in the catalytic module 104. Specifically, the second wavelength light absorbed by the catalytic module 104 can act on the upconversion agent to undergo an upconversion luminescence reaction, thereby converting the second wavelength light into the first wavelength light. The converted first wavelength light can then be absorbed by a photosensitive semiconductor material to undergo a photocatalytic reaction and generate bactericidal and deodorizing substances. That is, the catalytic module 104 can also be used to convert the second wavelength light into the first wavelength light through the upconversion agent, and to absorb the first wavelength light through a photosensitive semiconductor material to generate bactericidal and deodorizing substances, such as hydroxyl radicals and superoxide radicals.

[0059] Among them, the photosensitive semiconductor material can include a mixture of vanadium bismuth tetroxide and molybdenum oxide. The band gap of vanadium bismuth tetroxide is 2.4 eV. Since the band gap of vanadium bismuth tetroxide is relatively narrow, it is beneficial to absorb more short-wavelength light. Molybdenum oxide or molybdenum-based materials can promote the transfer of holes generated in the photocatalytic reaction of the photosensitive semiconductor material, thereby improving the photocatalytic efficiency and thus improving the sterilization and deodorization effect.

[0060] The top-conversion agent may include a mixture of trivalent erbium ions and yttrium aluminate, and may also include other rare earth materials.

[0061] Through the sonoluminescence of the ultrasonic module 103 and the photocatalytic reaction of the catalytic module 104, bactericidal and deodorizing substances can be generated by light of different wavelengths. Compared with light of only specific wavelengths such as ultraviolet light, which can generate bactericidal and deodorizing substances, this avoids the waste of long wavelength light and improves the bactericidal and deodorizing effect.

[0062] In some embodiments, after the ultrasonic module 103 emits ultrasonic waves and causes a cavitation effect with the water in the water reservoir 102, the cavitation causes the water to vibrate and generate bubbles. These bubbles continuously form and burst, resulting in localized high temperature and high pressure areas. These high temperature and high pressure areas can be called hot spots. These hot spots can undergo pyrolysis with the water in the water reservoir 102, i.e., the water decomposes upon heating, thereby generating hydroxyl radicals. Specifically, the ultrasonic waves emitted by the ultrasonic module 103 act on the water in the water reservoir 102, causing a pyrolysis reaction that generates bactericidal and deodorizing substances, including hydroxyl radicals.

[0063] It should be noted that since the ultrasonic module 103 is located inside the water reservoir 102, the ultrasonic waves generate hot spots through cavitation effects with the water. The pyrolysis of these hot spots with the water occurs within the water reservoir 102. Therefore, the generated bactericidal and deodorizing substances, i.e., hydroxyl radicals, need to be discharged from the water reservoir 102 and out of the bactericidal and deodorizing device 100 to achieve their bactericidal and deodorizing effects. Therefore, multiple openings can be provided on the side wall of the water reservoir 102, allowing the bactericidal and deodorizing substances to be discharged through these openings to the outside of the bactericidal and deodorizing device 100.

[0064] It is understandable that since the ultrasonic waves emitted by the ultrasonic module 103 act on the water in the water tank 102, different wavelengths of light are generated inside the water tank 102. If the different wavelengths of light are to be absorbed by the catalytic module 104, the water tank 102 needs to have light transmission capability, that is, the water tank 102 needs to be a light-transmitting material. The water tank 102 needs to be able to transmit light of different wavelengths, including long wavelengths and short wavelengths. For example, the water tank 102 can be made of transparent glass or other light-transmitting materials. The material of the water tank 102 is not specifically limited here.

[0065] It should be noted that the water storage tank 102, the ultrasonic module 103, and the catalytic module 104 are all located inside the housing 101. In order to allow the generated sterilizing and deodorizing substances to be discharged through the housing 101 to the outside of the sterilizing and deodorizing device 100, multiple through holes can be provided around the periphery of the housing 101. Thus, the sterilizing and deodorizing substances can be discharged from inside the housing 101 to the outside of the housing 101 through the multiple through holes, and sterilization and deodorization are achieved through the sterilizing and deodorizing substances.

[0066] In addition to the functions of photocatalysis by the acoustic luminescence and catalytic reaction of the catalytic module 104, and the generation of bactericidal and deodorizing substances by pyrolysis of the water in the water tank 102 through ultrasonic waves, the ultrasonic waves emitted by the ultrasonic module 103 can also atomize the water in the water tank 102 through high-frequency oscillation. The atomized water can be discharged to the outside of the bactericidal and deodorizing device 100 through the opening provided on the surface of the water tank 102, thereby achieving the function of atomization and humidification.

[0067] Specifically, ultrasound waves can break down the water in the water reservoir 102 into ultra-fine atomized particles through high-frequency oscillation. These ultra-fine atomized particles react with the water to form water mist, which can achieve the function of atomization and humidification. Furthermore, the generated water mist is cold mist, which also has a cooling effect and can improve the body's ability to absorb oxygen and expel carbon dioxide. In other words, the sterilization and deodorization device 100 not only has the function of sterilization and deodorization but also has the function of atomization and humidification.

[0068] It is understandable that since the atomized water is discharged through the opening of the water storage tank 102, and the bactericidal and deodorizing substance generated by the pyrolysis reaction between the ultrasonic waves and the water in the water storage tank 102 is also discharged through the opening of the water storage tank 102, the bactericidal and deodorizing substance and the atomized water can be discharged together from the opening to the bactericidal and deodorizing device, so that the bactericidal and deodorizing device 100 has three functions of bactericidal, deodorizing and humidifying at the same time.

[0069] As can be seen from the above, by installing a sterilization and deodorization device 100 inside the refrigerator 200, the problems of bacterial growth and odor inside the refrigerator 200 can be solved, and the food stored inside the refrigerator 200 can be kept moist, thus improving the user experience.
