[0004] The above solution has a technical problem. For example, it only treats the air with a filter and a UV lamp. Although the UV lamp can kill some microorganisms and reduce the generation of odors, it has a limited effect on removing odors in the air (such as smoke and other odors), and it is difficult to achieve the ideal purification effect on the air.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] In order to solve the technical problem that existing technologies cannot achieve ideal air purification effects, this utility model provides a sterilization and deodorization device.

[0032] The following describes in detail the specific structure of a sterilization and deodorization device provided by an embodiment of this utility model, according to the appendix. Figure 1-9 As shown, the specific structure of the sterilization and deodorization device includes a shell 1, a blowing assembly 2, a sterilization assembly 3, and a purification assembly 4.

[0033] according to Figure 3 and Figure 4 As shown, a purification chamber 11 is provided inside the outer casing 1, and the purification chamber 11 has multiple air inlets 12 and multiple air outlets 13.

[0034] Specifically, the outer casing 1 is the main structure of the entire sterilization and deodorization equipment. It encapsulates internal components such as the blower assembly 2, purification module 41, electrostatic module 42, sterilization assembly 3, and activated carbon module 43, preventing damage to these modules from the external environment and ensuring the safety of the sterilization and deodorization equipment during use. Furthermore, the purification chamber 11 inside the outer casing 1 forms a relatively sealed space, allowing air to enter only through the air inlet 12. After passing through each module and component along a predetermined path, air is finally discharged from the air outlet 13. This sealing ensures the efficiency and continuity of the air handling process. The purification chamber 11 provides installation positions for the blower assembly 2, purification module 41, electrostatic module 42, sterilization assembly 3, and activated carbon module 43, allowing these modules and components to be arranged orderly within the purification chamber 11, forming a complete air handling system. The air inlet 12 is the channel for external air to enter the purification chamber 11. The amount of air entering can be increased by having multiple air inlets 12 through the outer shell 1. The air outlet 13 is the channel for exhausting the purified, sterilized and deodorized air out of the purification chamber 11.

[0035] It should be noted that the diameter of the air inlet 12 and the air outlet 13 can be designed according to actual needs. For example, the diameter of each air inlet 12 and air outlet 13 is <8mm. This diameter can prevent most people's fingers from being directly inserted into the purification chamber 11, thus preventing users' fingers from accidentally sticking in and avoiding electric shock, ultraviolet burns or mechanical injuries. It can also prevent foreign objects such as paper scraps, coins, and small toys from falling into the purification chamber 11 to protect the internal structure.

[0036] according to Figure 3 As shown, the blower assembly 2 is built into the purification chamber 11.

[0037] Specifically, the blower assembly 2 generates airflow to circulate air within the purification chamber 11. After entering the purification chamber 11 through the air inlet 12, the air first undergoes preliminary filtration through the purification module 41, then passes through the electrostatic module 42 which uses static electricity to adsorb and remove dust. Subsequently, it is drawn into the blower assembly 2 and guided to the sterilization assembly 3 for sterilization. Finally, it passes through the activated carbon module 43 to remove odors and is discharged from the air outlet 13. Therefore, the airflow generated by the blower assembly 2 in this embodiment directly affects the airflow speed within the purification chamber 11 and improves purification efficiency.

[0038] In addition, the blower assembly 2 can ensure that the air has sufficient residence time by controlling the appropriate wind speed, so that each module can fully process the air.

[0039] according to Figure 3 and Figure 4 As shown, the purification component 4 includes a purification module 41, an electrostatic module 42, and an activated carbon module 43; wherein, the purification module 41 is built into the purification chamber 11 and is arranged opposite to each air inlet 12.

[0040] Specifically, after air enters the purification chamber 11 through the air inlet 12 on the outer casing 1, it will first come into contact with the purification module 41. Multiple air inlets 12 guide the air to be evenly distributed on the surface of the purification module 41, ensuring that the air can fully contact the filter screen of the purification module 41. After the air enters the purification chamber 11, it will be guided by the airflow generated by the blower assembly 2 and flow to the purification module 41. Because the purification module 41 is positioned opposite the air inlet 12, air can directly enter the filter. When the air passes through the filter, larger particles (such as dust, hair, pollen, etc.) are intercepted by the filter of the purification module 41. These particles cannot pass through the pores of the filter of the purification module 41 and are thus trapped on the surface of the filter. For some larger particles, when the airflow speed is high, the particles will deviate from the airflow direction due to inertia, collide with the filter of the purification module 41, and be intercepted. For some smaller particles, due to their diffusion effect in the air, they will randomly come into contact with the filter of the purification module 41 and be intercepted. After being processed by the purification module 41, the large dust particles and impurities in the air are intercepted, making the air cleaner. The purified air will continue to flow to the electrostatic module 42.

[0041] It should be noted that the purification module 41 of this utility model embodiment effectively intercepts large dust particles and impurities in the air through its multi-layer filter structure, utilizing principles such as physical interception, inertial collision, and diffusion interception.

[0042] It is understood that the purification module 41 in this embodiment of the present invention is a pre-filter, a medium-efficiency filter, or an activated carbon fiber layer. For example, a pre-filter is used to intercept larger particles of dust and impurities, such as hair, dust, and pollen. Specifically, the pre-filter is made of coarse fiber material and has a larger pore size, which can effectively intercept larger particles of pollutants. Alternatively, a medium-efficiency filter is used to further intercept smaller particles of dust and impurities. The medium-efficiency filter is made of fine fiber material and has a smaller pore size, which can intercept even finer particles. Or, an activated carbon fiber layer is used, incorporating an activated carbon fiber layer into the filter of the purification module 41, to adsorb odors and harmful gases in the air, such as formaldehyde and benzene.

[0043] The electrostatic module 42 is built into the purification chamber 11 and is located between the air intake end of the blower assembly 2 and the purification module 41.

[0044] Specifically, the electrostatic module 42 includes an ionization zone, a dust collection zone, and a high-voltage power supply. The ionization zone generates a high-voltage electric field to charge airborne particles, while the dust collection zone adsorbs the charged particles. The high-voltage power supply provides high voltage to both the ionization and dust collection zones. After initial filtration by the purification module 41, air enters the ionization zone of the electrostatic module 42. The ionization zone is located between the air intake of the blower assembly 2 and the purification module 41, ensuring that most large particulate impurities are removed before the air enters the electrostatic module 42. When the high-voltage power supply is energized, a high-voltage electric field is generated within the ionization zone. When airborne particles pass through the ionization zone, they are ionized by the electric field generated by the ionization wire, acquiring positive or negative charges. The high-voltage electric field in the ionization zone ionizes gas molecules in the air, generating a large number of ions and free electrons. These ions and free electrons collide with airborne particles, charging them. The charged particles are then pushed towards the dust collection zone by the electric field force.

[0045] Therefore, it can be seen that the electrostatic module 42, through the synergistic effect of the ionization zone and the dust collection zone, utilizes the principle of electrostatic field to ionize and adsorb fine particulate matter in the air onto the dust collection plate, thereby achieving efficient air purification.

[0046] The sterilization component 3 is built into the purification chamber 11 and is positioned opposite to the air blowing end of the blower component 2.

[0047] Specifically, the air after electrostatic dust removal is directed by the airflow of the blower assembly 2 to the sterilization assembly 3. The sterilization assembly 3 and the blower assembly 2 are positioned opposite each other to ensure that the air can directly enter the sterilization assembly 3 after passing through the blower assembly 2. This arrangement can maximize the use of airflow energy and improve sterilization efficiency. Moreover, with the synergistic effect of the sterilization assembly 3 and the blower assembly 2, not only can the sterilization efficiency be improved, but the operating efficiency of the equipment can also be ensured. Finally, the airflow generated by the blower assembly 2 can blow the sterilized air to the activated carbon module 43.

[0048] The activated carbon module 43 is built into the purification chamber 11 and is located between the sterilization component 3 and each air outlet 13.

[0049] Specifically, activated carbon module 43 is an activated carbon filter, which can be understood as being made of granular activated carbon or activated carbon fibers. Because the surface area of ​​the activated carbon filter is relatively large, for example, between 500-3000 square meters per gram, the surface of the activated carbon has a large number of micropores and fine pores, capable of adsorbing a large number of gas molecules. The microporous structure of the activated carbon filter enables it to adsorb small molecule gases in the air, thus effectively adsorbing harmful gases such as formaldehyde, benzene, and ammonia. The surface of activated carbon contains a large number of functional groups (such as hydroxyl, carboxyl, and carbonyl groups), which can chemically react with harmful gases in the air, further improving the adsorption effect.

[0050] After being treated by the sterilization component 3, the air enters the activated carbon module 43. At this point, bacteria and viruses in the air have been killed, but odors and harmful gases may still be present. Therefore, when the air passes through the activated carbon filter, odor molecules and harmful gases (such as formaldehyde, benzene, ammonia, TVOC, etc.) are adsorbed by the microporous structure of the activated carbon. After being treated by the activated carbon module 43, the odors and harmful gases in the air are removed, making the air fresher. The purified air continues to flow to the air outlet 13 and is eventually discharged outside the purification chamber 11. The activated carbon module 43, with its large surface area and porous structure, effectively removes odors and harmful gases from the air using the principles of physical and chemical adsorption. The activated carbon module 43 is located between the sterilization component 3 and the air outlet 13, ensuring that the air treated by sterilization can be further deodorized and free of harmful substances before being discharged from the equipment.

[0051] according to Figure 5 and Figure 6 As shown, in some specific embodiments, the sterilization component 3 includes a mounting frame 31, two sterilization nets 33, and multiple ultraviolet lamps 34; the mounting frame 31 is built into the purification chamber 11, and the mounting frame 31 has an airflow port 32 through it; the two sterilization nets 33 are respectively disposed at both ends of the airflow port 32, one of which is disposed opposite to the blowing end of the blowing component 2, and the other is disposed opposite to the activated carbon module 43; each ultraviolet lamp 34 is disposed in the purification chamber 11 and located between the two sterilization nets 33.

[0052] Specifically, the mounting bracket 31 is used to fix the sterilization net 33 and the ultraviolet lamp tube 34. The mounting bracket 31 is built into the purification chamber 11 to ensure the stability and safety of the entire sterilization component 3. Two sterilization nets 33 are respectively set at both ends of the airflow chamber opening 32. One is set opposite to the air blowing end of the blowing component 2, and the other is set opposite to the activated carbon module 43. The function of the sterilization net 33 is to enhance the penetration effect of ultraviolet light and prevent airborne particles from directly contacting the ultraviolet lamp tube 34, protecting the ultraviolet lamp tube 34 from contamination. Multiple ultraviolet lamp tubes 34 are set between the two sterilization nets 33 to emit ultraviolet light to sterilize microorganisms in the air.

[0053] The sterilization component 3 works in synergy with the blowing component 2. For example, the blowing component 2 provides power to pass air through the sterilization component 3, ensuring that the air has sufficient residence time under ultraviolet irradiation, thereby achieving a highly efficient sterilization effect. In synergy with the activated carbon module 43, the microorganisms in the air treated by the sterilization component 3 are killed, but odors and harmful gases may still remain. The activated carbon module 43 can further remove these odors and harmful gases, ensuring that the air achieves optimal purification before being discharged from the purification chamber 11.

[0054] For example, in the operation of the sterilization component 3, the air, after being treated by the electrostatic module 42 and the purification module 41, enters the airflow chamber 32 of the sterilization component 3. At this time, large dust particles and fine particulate matter in the air have been removed, but bacteria and viruses may still exist. When the air passes through the airflow chamber 32, it passes through the area between the two sterilization nets 33. At this time, the air is exposed to the ultraviolet light emitted by the ultraviolet lamp 34. The high-energy photons emitted by the ultraviolet lamp 34 can penetrate the microorganisms in the air and destroy their DNA or RNA structure, thereby achieving a sterilization effect. After the air is treated by ultraviolet sterilization, the bacteria and viruses in the air are inactivated, and the air becomes safer and more hygienic. The purified air continues to flow to the activated carbon module 43 to further remove odors and harmful gases, and finally is discharged from the air outlet 13.

[0055] It should be noted that the ultraviolet lamp 34 in this embodiment of the invention utilizes high-energy photons of ultraviolet light to destroy the DNA or RNA structure of microorganisms, rendering them unable to reproduce and infect. For example, the wavelength range of ultraviolet light is between 100-400 nanometers, with 254-nanometer ultraviolet light possessing the strongest bactericidal ability. The ultraviolet lamp 34 uses a low-pressure mercury lamp or an ultraviolet LED lamp. Each ultraviolet LED lamp emits ultraviolet light, for example, at 254 nanometers, after being powered on. The ultraviolet photons emitted by the ultraviolet lamp 34 have high energy and can penetrate the cell wall and cell membrane of microorganisms, acting on their DNA or RNA. Therefore, after ultraviolet irradiation, bacteria, viruses, and other microorganisms in the air are inactivated, losing their ability to reproduce and infect, thereby achieving air sterilization and disinfection.

[0056] Therefore, it can be seen that the sterilization effect is enhanced by the combined action of the ultraviolet rays emitted by the sterilization nets 33 and the ultraviolet lamps 34 in this embodiment of the present invention.

[0057] according to Figure 7 and Figure 8 As shown, in a further embodiment, a first positioning plate 35 and a second positioning plate 36 are provided in the airflow cavity 32. Both the first positioning plate 35 and the second positioning plate 36 are provided with a plurality of spaced positioning holes 37. One end of each ultraviolet lamp tube 34 passes through the positioning hole 37 of the first positioning plate 35, and the other end of each ultraviolet lamp tube 34 passes through the positioning hole 37 of the second positioning plate 36.

[0058] Specifically, both the first positioning plate 35 and the second positioning plate 36 are built into the airflow cavity 32 to fix the position of the ultraviolet lamp tubes and ensure that each ultraviolet lamp tube is stably installed within the airflow cavity 32. Both the first positioning plate 35 and the second positioning plate 36 are provided with multiple spaced positioning holes 37, which are used to pass through both ends of the ultraviolet lamp tubes and fix them at designated positions within the airflow cavity 32.

[0059] For example, one end of the ultraviolet lamp is inserted into the positioning hole 37 of the first positioning plate 35, and the other end is inserted into the positioning hole 37 of the second positioning plate 36, so that the ultraviolet lamp is fixed in the airflow cavity 32, ensuring that the ultraviolet lamps will not shift due to the impact of airflow or the vibration of the equipment. The positioning holes 37 allow the ultraviolet lamps to be evenly distributed in the airflow cavity 32, ensuring that the ultraviolet light can be evenly irradiated into the air passing through the airflow cavity 32. This even distribution helps to improve the sterilization efficiency and ensures that the microorganisms in the air can be fully exposed to ultraviolet light. The air treated by the electrostatic module 42 enters the airflow cavity 32 through the blowing end of the blower assembly 2. At this time, the air has been initially purified, removing most of the particulate matter. When the air passes through the airflow cavity 32, it will be irradiated by the ultraviolet light emitted by the ultraviolet lamp. The ultraviolet light can penetrate the microbial cells in the air, destroy their DNA or RNA structure, and make the microorganisms lose their activity, thereby achieving the purpose of sterilization and disinfection. The air after ultraviolet irradiation continues to flow through the airflow cavity 32 to the activated carbon module 43 for further purification treatment.

[0060] It should be noted that the positioning holes 37 are spaced apart to ensure that the ultraviolet lamps are evenly distributed within the airflow cavity 32. This even distribution helps to improve the coverage of ultraviolet light, ensuring that airborne microorganisms are fully exposed to ultraviolet irradiation. Furthermore, the layout of the ultraviolet lamps can be optimized by rationally designing the spacing and number of the positioning holes 37, thereby improving the overall efficiency of the sterilization component 3. For example, increasing the number and distribution density of ultraviolet lamps can further improve the sterilization effect.

[0061] according to Figure 8 As shown, in a further embodiment, the second positioning plate 36 is located below the first positioning plate 35, and the second positioning plate 36 is provided with a plurality of support portions 38 for supporting each ultraviolet lamp tube 34.

[0062] Specifically, the support portion 38 on the second positioning plate 36 provides a stable support point for the ultraviolet lamp tube 34. For example, each support portion 38 is a bracket that can firmly fix each ultraviolet lamp tube 34 and prevent it from shifting or shaking due to vibration or airflow impact during operation. That is, by using the support portion 38, the ultraviolet lamp tube 34 can be accurately installed in a predetermined position. By inserting one end of each ultraviolet lamp tube 34 into the positioning hole 37 of the corresponding first positioning plate 35 and the other end of each ultraviolet lamp tube 34 into the support portion 38 of the corresponding second positioning plate 36, the ultraviolet lamp tube 34 can be accurately fixed in the airflow cavity 32.

[0063] In another embodiment, both the first positioning plate 35 and the second positioning plate 36 are vertically arranged, and correspondingly, each ultraviolet lamp tube 34 is horizontally arranged, with both ends of each ultraviolet lamp tube 34 inserted into the positioning holes 37 of the first positioning plate 35 and the second positioning plate 36, respectively. The orientation of the first positioning plate 35 and the second positioning plate 36 can be set according to actual needs and is not specifically limited here.

[0064] according to Figure 5 and Figure 6 As shown, in a further embodiment, the sterilization component 3 also includes two fixing frames 39, each fixing frame 39 being detachably disposed around each sterilization net 33 to fix each sterilization net 33.

[0065] Specifically, each fixing frame 39 includes a frame body, a locking element, and a sealing strip. A sterilization mesh 33 is used to intercept airborne particles and prevent them from adhering to the surface of the ultraviolet lamp tube 34. The fixing frame 39 is connected to the sterilization mesh 33 via the locking element, firmly fixing the sterilization mesh 33 to the mounting bracket 31. The fixing frame 39 ensures that the sterilization mesh 33 will not shift or deform during airflow, ensuring the stability of each sterilization mesh 33. A sealing strip is provided between the fixing frame 39 and the sterilization mesh 33, ensuring that air can only pass through the filter layer of the sterilization mesh 33 and will not bypass it from the side. This sealing design improves the sterilization efficiency of the sterilization component 3.

[0066] It is understood that the mounting bracket 31 of this utility model embodiment has a threaded hole, the sterilization mesh 33 has a through alignment hole, and the locking member is a bolt. The bolt is inserted into both the alignment hole and the threaded hole, and the bolt engages with the threaded hole so that the sterilization mesh 33 is fixedly attached to the mounting bracket 31.

[0067] according to Figure 9 As shown, in some specific embodiments, the blower assembly 2 includes a support plate 21 and at least one fan 22. The support plate 21 is built into the purification chamber 11 and has a ventilation hole 23. The fan 22 is disposed on the support plate 21, and the air intake end or air blowing end of the fan 22 faces the ventilation hole 23.

[0068] Specifically, the support plate 21 is used to fix the fan 22 and is installed inside the purification chamber 11. The support plate 21 has ventilation holes 23 to ensure smooth airflow. At least one fan 22 is mounted on the support plate 21, with its intake or exhaust end facing the ventilation hole 23. The fan 22 is the power source for airflow, i.e., it generates airflow. The fan 22 consists of a motor and blades. When the fan blades rotate, a negative pressure is generated at its intake end, drawing in air; at its exhaust end, air is blown out. When the intake end of the fan 22 faces the ventilation hole 23, air enters the support plate 21 through the ventilation hole 23 and is drawn into the fan 22. At this time, air flows from the air intake area of ​​the purification chamber 11 to the fan 22. When the exhaust end of the fan 22 faces the ventilation hole 23, air is blown through the fan 22 towards the ventilation hole 23 and enters the next module of the purification chamber 11.

[0069] Understandably, multiple fans 22 can be set according to actual needs. Multiple fans 22 can work simultaneously, significantly increasing the air handling capacity of the sterilization and deodorization equipment. This allows more air to be processed in a shorter time, thereby improving the overall purification efficiency. Moreover, multiple fans 22 can optimize airflow distribution, making the air flow more evenly in the purification chamber 11. This helps ensure that the air can fully contact each module in the purification component 4, improving the purification, sterilization, and deodorization effects.

[0070] according to Figure 1 and Figure 2 As shown, in some specific embodiments, the sterilization and deodorization device also includes a control component 5, which is disposed on the outside of the housing 1 and is connected to the blower component 2, the sterilization component 3 and the electrostatic module 42; the control component 5 is provided with a power supply interface 51.

[0071] Specifically, the power supply interface 51 is a standard power socket for connecting to an external power source (such as 220V AC). Once the power is connected, the control component 5 distributes electrical energy to various components requiring power, such as the motor, UV lamps, and electrostatic module 42, through its internal circuitry. The control component 5 includes a knob and a switch. The knob adjusts the airflow of the fan 22 from minimum to maximum, while the switch controls the device's on / off state. When the knob is at its minimum position, the motor stops, keeping the entire sterilization and deodorization device stationary. Conversely, when the knob is at its maximum position, the motor runs at its highest speed, and the fan 22 provides maximum airflow. This mode is suitable for highly polluted environments to improve the purification efficiency of the sterilization and deodorization device. The rotation of the knob is converted into a motor speed signal by the control circuit. The control circuit uses PWM (Pulse Width Modulation) technology, which precisely controls the motor speed by changing the pulse width of the motor's supply voltage or current.

[0072] Therefore, control component 5 provides power to the sterilization and deodorization equipment through power interface 51, and controls the blower component 2, sterilization component 3, and electrostatic module 42 through knobs and switches. The knobs adjust the airflow of fan 22, continuously adjusting it from off or minimum airflow to maximum airflow; the switches control the on / off operation of the sterilization and deodorization equipment. The control circuit is the core of control component 5, implementing logic control of the sterilization and deodorization equipment through a built-in microcontroller or integrated circuit, including airflow adjustment, sterilization, and electrostatic dust removal control.

[0073] according to Figure 1 and Figure 4 As shown, in some specific embodiments, the outer casing 1 includes a box body 14 and a box cover 15, the purification chamber 11 is located inside the box body 14, and the box cover 15 is detachably disposed on the top of the box body 14.

[0074] Specifically, the housing 14 is the main part of the outer shell 1, used to house the various components inside the sterilization and deodorization equipment, such as the blowing assembly 2, purification module 41, electrostatic module 42, sterilization assembly 3, and activated carbon module 43. The housing 14 is made of a robust material, such as metal or high-strength plastic, to ensure the stability and durability of the sterilization and deodorization equipment. The cover 15 is installed on top of the housing 14 to seal the housing 14. Since the cover 15 has a removable design, it is convenient for users or maintenance personnel to open the housing 14 for maintenance or component replacement. Specifically, the outer shell 1 provides physical protection for the internal components of the equipment, preventing damage to the components from the external environment (such as dust, moisture, mechanical impact, etc.). Moreover, the design of the housing 14 and the cover 15 forms a relatively sealed space, ensuring that air can only enter the purification chamber 11 through the air inlet 12, pass through the various modules according to a predetermined path, and finally be discharged from the air outlet 13. This airtightness helps to improve the operating effect of the sterilization and deodorization equipment.

[0075] according to Figure 4 As shown, in a further embodiment, the sterilization and deodorization device also includes a sealing cover 16, which is disposed at the top opening of the purification chamber 11 and is located below the cover 15.

[0076] Specifically, the sealing cover 16 is used to ensure the airtightness of the purification chamber 11 and prevent air from leaking out from the top opening. For example, by placing the sealing cover 16 at the top opening of the purification chamber 11 and positioning it below the cover 15, the sealing cover 16 can tightly fit the top opening of the chamber 14, improving the airtightness of the purification chamber 11. This ensures that air can only enter and exit the purification chamber 11 through the air inlet 12 and the air outlet 13, preventing leakage of air that has not been completely purified and disinfected.

[0077] according to Figure 1 and Figure 2As shown, in some specific embodiments, the bottom of the housing 1 is provided with a plurality of casters 17.

[0078] Specifically, the use of casters 17 allows the sterilization and deodorization equipment to move freely in multiple directions. This allows users to easily move the equipment to the desired location without the need for multiple people to carry it. This flexibility is particularly suitable for situations requiring frequent movement of the equipment, such as hospitals, schools, and offices. The casters 17 use rolling friction instead of sliding friction, further reducing the force required to move the entire sterilization and deodorization equipment. Therefore, users can easily push the equipment, even if it is heavy. Furthermore, the multiple casters 17 evenly distribute the weight of the equipment, reducing concentrated pressure on the ground and improving the stability of the equipment during operation.

[0079] It should be noted that each of the casters 17 is a foot-operated brake caster 17. By operating the foot pedal, the user can easily press down or release the brake with their foot, thus fixing the entire sterilization and deodorization equipment in its current position.

[0080] according to Figure 1 As shown, in some specific embodiments, a handle 18 is also provided on the outer side of the outer casing 1 (specifically, the side of the housing 14 where the air inlet 12 is located). The handle 18 provides a convenient gripping position for the user, allowing the user to easily move the entire device. For example, the user only needs to hold the handle 18 to push the entire sterilization and deodorization device forward or backward.

[0081] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
