[0029] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] It should also be noted that when an element is referred to as being “fixed on” or “disposed on” another element, the element may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0032] See also Figures 1 to 7 An embodiment of the present invention provides an odor removal device 10 for removing odors from the air. The odor refers to an unpleasant smell that causes discomfort to people, such as a foul smell or a musty smell. This application uses the odor as an example to illustrate that the odor removal device 10 can remove odors from the air, thereby achieving the effect of purifying the air.

[0033] Deodorizing device 10 includes a housing 12, a fan 14, and a deodorizing element 16 located within housing 12. Housing 12 is provided with an air inlet 18 and an air outlet 20 that communicate with each other. Fan 14 is mounted within housing 12, and deodorizing element 16 is located within an airflow channel 22 connecting air inlet 18 and air outlet 20. When fan 14 is in operation, it draws ambient air, i.e., air from the environment outside of deodorizing device 10, through air inlet 18 into airflow channel 22. As air moves along airflow channel 22 toward air outlet 20, it passes through deodorizing element 16, removing odors from the air. The deodorized air is then discharged into the outside environment through air outlet 20, thereby purifying the air. Specifically, fan 14 is mounted within housing 12 and located within airflow channel 22. As air flows through airflow channel 22, it passes through fan 14.

[0034] The specific method by which the deodorizing element 16 removes odors is not limited. For example, it may be performed by ultraviolet disinfection or plasma technology. In the present application, the deodorizing element 16 is a plasma generator that ionizes the air to generate a large number of positive and negative ions. The ionization releases a large amount of energy, which eliminates pollutants in the air, such as bacteria, thereby eliminating odors and improving air quality.

[0035] The specific type of fan 14 is not limited, and it can be an axial flow fan or a centrifugal fan. In this embodiment, the fan 14 is a centrifugal fan, and its air inlet direction and air outlet direction are perpendicular to each other. Compared with the axial flow fan, the centrifugal fan has a larger air volume and wind speed to improve the efficiency of air purification.

[0036] The air flow channel 22 can be located inside the shell 12 or inside the fan 14. In this embodiment, the air flow channel 22 is located inside the fan 14, and the deodorizing element 16 is located inside the air flow channel 22, that is, the deodorizing element 16 is located inside the fan 14, which makes full use of the internal space of the fan 14 and helps to improve the compactness of the overall structure.

[0037] In this embodiment, the housing 12 is substantially square, and the air inlet 18 and the air outlet 20 are respectively disposed on opposite sides of the housing 12 .

[0038] The fan 14 includes a volute 24 and a rotor 26 located within the volute 24. The interior of the volute 24 forms an airflow passage 22. The rotor 26 rotates within the airflow passage 22. The deodorizing element 16 is located within the volute 24 and spaced apart from the rotor 26. Rotation of the rotor 26 drives air through the airflow passage 22 within the volute 24, thereby passing through the deodorizing element 16. Mounting the deodorizing element 16 within the volute 24 provides a certain degree of protection for the deodorizing element 16.

[0039] Specifically, the fan 14 further includes a driving member 28 such as a motor. The driving member 28 is fixedly installed inside the housing 12 and connected to the wind wheel 26 to drive the wind wheel 26 to rotate relative to the housing 12, thereby driving air flow.

[0040] Deodorizing element 16 is located between the airflow outlet of impeller 26 and air outlet 20. The side of impeller 26 near air inlet 18 is the airflow inlet, and the side near air outlet 20 is the airflow outlet. After entering airflow channel 22 through air inlet 18, outside air first passes through impeller 26 and then through deodorizing element 16. Because deodorizing element 16 may generate ozone during the deodorizing process, and ozone is highly oxidizing, positioning deodorizing element 16 near the airflow outlet of impeller 26 prevents ozone generated during the deodorizing process from contacting and corroding impeller 26.

[0041] A power supply 30 is further provided inside the housing 12 . The power supply 30 is located outside the volute 24 and is electrically connected to the deodorizing element 16 , thereby providing electrical energy for the deodorizing element 16 to operate.

[0042] One side of the volute 24 is open, and the side of the volute 24 closest to the opening is sealed against the inner surface of the housing 12. The airflow passage 22 is located between the volute 24 and the inner surface of the housing 12. By forming an opening on one side of the volute 24 and covering the opening with the housing 12, the inner surface of the housing 12 serves as a barrier for one side of the airflow passage 22. This helps reduce the overall volume of the volute 24, thereby reducing the space required for its installation. Furthermore, the sealed fit between the volute 24 and the housing 12 prevents air from escaping the gap between the volute 24 and the housing 12 when flowing in the airflow passage 22, allowing more air to pass through the deodorizing element 16.

[0043] The specific manner in which the volute 24 and the shell 12 are sealed is not limited. For example, a glue layer may be provided between the volute 24 and the shell 12 so that the volute 24 and the shell 12 are glued and fixed, for example, the glue layer forms a sealing effect. Alternatively, a sealing ring may be provided between the volute 24 and the shell 12 so as to form a sealing effect using the sealing ring.

[0044] The housing 12 includes a main body 32 and a side panel 34 mounted on one side of the main body 32. The main body 32 and the side panel 34 enclose a storage space within which the fan 14 is located. The volute 24 is fixedly connected to the side panel 34 to form a seal. The housing 12 is configured as two parts: the main body 32 and the side panel 34. During assembly, the main body 32 and the side panel 34 can be separated first. After the fan 14 is mounted on the side panel 34, the main body 32 can then be placed on the side panel 34 to cover the fan 14, thereby reducing assembly difficulty.

[0045] The connection method between the shell body 32 and the side panels 34 is not limited, and can be connected by connecting members or snap connections. In this embodiment, the inner side of the side panels 34 is provided with a plurality of mounting posts, and connecting members such as screws are installed on the mounting posts and connected to the shell body 32, thereby fixing the shell body 32 and the side panels 34 together.

[0046] In one embodiment, the volute 24 includes a housing 36 and a flow guide 38, which are interconnected. The housing 36 is disposed outside the impeller 26 and communicates with the air inlet 18. The flow guide 38 extends from the outside of the housing 36 toward the air outlet 20 and communicates with the air outlet 20. The deodorizing element 16 is located within the flow guide 38. When the impeller 26 is in operation, external air first enters the housing 36 through the air inlet 18, flows through the impeller 26, and then enters the flow guide 38. The flow guide 38 serves to guide the air toward the air outlet 20. During the flow, the air passes through the deodorizing element 16, where it is deodorized before being discharged from the air outlet 20.

[0047] Specifically, an inlet is provided on the side of the cover body 36 close to the air inlet 18, and an outlet is provided on the side of the guide portion 38 close to the air outlet 20. One end of the air flow channel 22 is connected to the air inlet 18 through the inlet, and the other end is connected to the air outlet 20 through the outlet.

[0048] The specific connection method between the cover body 36 and the guide portion 38 is not limited and can be integrally formed or separately connected. In this embodiment, the cover body 36 and the guide portion 38 are integrally formed to eliminate the assembly process between the two, ensure the connection strength, and also form a better sealing effect.

[0049] In this embodiment, the outline shape of the cover body 36 is basically circular, and the outline shape of the guide part 38 is basically square. The connection between the cover body 36 and the guide part 38 can form a relatively large installation space, and the power supply 30 is installed in the installation space to improve the compactness of the overall structure.

[0050] In one embodiment, a dust filter assembly 40 is provided at the air inlet 18. When the outside air enters the air flow channel 22 through the air inlet 18 under the action of the fan 14, the outside air will first pass through the dust filter assembly 40. The dust filter assembly 40 can filter out dust in the air and prevent dust from entering the air flow channel 22 with the air. It can effectively prevent the deodorization device 10 from accumulating dust inside the shell 12 after running for a long time, causing the internal components such as the fan 14 and the deodorization component 16 to become dirty. At the same time, it can also prevent dust from affecting the operation and service life of the fan 14 and the deodorization component 16, thereby improving the dustproof performance of the deodorization device 10.

[0051] It can be understood that a dust filter assembly 40 is provided at the air inlet 18, which may mean that the dust filter assembly 40 is located inside the air inlet 18, or it may mean that the dust filter assembly 40 is located on the inside or outside of the air inlet 18, as long as it can cover the air inlet 18 and allow the outside air to pass through the dust filter assembly 40 before entering the air flow channel 22.

[0052] The dust filter assembly 40 is detachably connected to the shell 12, so that the dust filter assembly 40 can be removed from the shell 12 for cleaning or replacement after being used for a period of time, to prevent dust from accumulating on the dust filter assembly 40 and affecting the air intake or dust prevention effect.

[0053] There is no limitation on the specific method of detachable connection between the dust filter assembly 40 and the shell 12, such as a snap connection or a magnetic connection. The snap connection and the magnetic connection form a detachable connection effect. Compared with the connection method using a connector, the dust filter assembly 40 is simple to install on the shell 12 or remove from the shell 12, which facilitates the disassembly and assembly of the dust filter assembly 40.

[0054] In this embodiment, the dust filter assembly 40 is connected to the shell 12 by snapping. A buckle body is provided on the dust filter assembly 40, and a buckle hole is correspondingly provided on the shell 12. The buckle body is buckled into the buckle hole to install the dust filter assembly 40 to the shell 12. After the buckle body is withdrawn from the buckle hole, the dust filter assembly 40 can be removed from the shell 12.

[0055] In other embodiments, buckle holes may be provided on the dust filter assembly 40 and buckle bodies may be provided on the housing 12 to achieve a snap-fit effect.

[0056] It can be understood that in order to facilitate the installation of the dust filter assembly 40, a positioning structure can be set between the dust filter assembly 40 and the shell 12. For example, a positioning column is set on one of them and a corresponding positioning hole is set on the other. The cooperation between the positioning column and the positioning hole can form a positioning effect during the installation process of the dust filter assembly 40, thereby assisting the installation of the dust filter assembly 40.

[0057] In this embodiment, an operating portion 42 is provided on the outside of the dust filter assembly 40. The operating portion 42 protrudes from the outer surface of the dust filter assembly 40. During the installation and disassembly of the dust filter assembly 40, the operating portion 42 can be grasped by hand to facilitate the installation and disassembly of the dust filter assembly 40.

[0058] It is understandable that the operating portion 42 can be a bump protruding from the surface of the dust filter assembly 40, or a handle fixedly installed on the outside of the dust filter assembly 40.

[0059] In other embodiments, the operating portion 42 is recessed in the outer surface of the dust filter assembly 40 to form a hand-holding position, so that the fingers can be inserted into the operating portion 42 and hooked on the operating portion 42, which can also facilitate the installation and disassembly of the dust filter assembly 40.

[0060] Preferably, two operating portions 42 are provided on the outer surface of the dust filter assembly 40 , and the two operating portions 42 are spaced apart from each other so as to be operated by both hands.

[0061] The dust filter assembly 40 includes a plurality of dust filters 44 arranged along the direction of the air inlet 18, that is, the direction in which the air enters the air flow channel 22 through the air inlet 18. When the outside air enters the air flow channel 22, it will pass through the plurality of dust filters 44 in sequence. Each dust filter 44 can form a filtering effect on the passing air, thereby forming a multi-stage filtering effect on the passing air, enhancing the filtering effect of the dust filter assembly 40, making it more difficult for dust in the outside air to enter the interior of the shell 12, and enhancing the dustproof performance of the deodorization device 10.

[0062] The specific number of dust filters 44 is not limited, and can be two, three, or more than three. Furthermore, the filtering capacity of each dust filter 44 can be the same or different. For example, the filtering capacity of multiple dust filters 44 gradually increases as air passes through the air inlet 18. In this embodiment, there are two dust filters 44, each comprising a primary filter and a secondary filter. The secondary filter is located inside the primary filter and has a greater filtering capacity than the primary filter. Before entering the airflow channel 22, the outside air is first initially filtered by the primary filter to remove larger dust particles, and then is secondary filtered by the secondary filter to further remove smaller dust particles.

[0063] The dust filter assembly 40 also includes an air inlet grille 46 connected to the housing 12. The air inlet grille 46 is provided with a plurality of grille holes for air to enter. The air inlet grille 46 is detachably connected to the housing 12. The dust filter 44 is located inside the air inlet grille 46 to protect the dust filter 44. After the air inlet grille 46 is removed from the housing 12, the dust filter 44 can be removed for cleaning or replacement.

[0064] In this embodiment, the air inlet grille 46 is snap-fitted or magnetically connected to the housing 12 to form a detachable connection with the housing 12. The operating portion 42 of the dust filter assembly 40 is located on the outside of the air inlet grille 46 to facilitate installation and removal of the air inlet grille 46. The primary filter is fixed to the inside of the air inlet grille 46, and the secondary filter is located inside the air inlet grille 46 and spaced apart from the air inlet grille 46. When installing the dust filter assembly 40 to the housing 12, the primary filter can be first fixed to the inside of the air inlet grille 46, then the secondary filter can be installed at the air inlet 18 of the housing 12, and then the air inlet grille 46 can be installed to the housing 12. When removing the dust filter assembly 40 from the housing 12, the air inlet grille 46 can be first removed from the housing 12, and then the secondary filter can be removed from the housing 12. The secondary filter can be cleaned or replaced as needed. After cleaning, the air inlet grille 46 and the primary filter can be used again.

[0065] In one embodiment, an ozone removal filter assembly 48 is provided at the air outlet 20. The deodorizing element 16 may generate ozone in the process of removing odors from the air. Direct discharge of ozone into the external environment may cause discomfort to people. By providing the ozone removal filter assembly 48 at the air outlet 20, the deodorized air first passes through the ozone removal filter assembly 48 to filter out the ozone in the air, and then is discharged from the air outlet 20, thereby avoiding the problem of ozone causing discomfort to people.

[0066] In this embodiment, the deodorizing element 16 is a plasma generator. During operation, the plasma generator decomposes oxygen in the air into oxygen atoms. The oxygen atoms generate ozone through chemical reactions. The ozone follows the air and moves toward the air outlet 20 driven by the fan 14. When passing through the air outlet 20, the air will pass through the ozone removal filter assembly 48. The ozone removal filter assembly 48 can decompose ozone into oxygen, thereby preventing the ozone generated by the plasma generator from being discharged into the external environment.

[0067] It can be understood that the ozone removal filter assembly 48 is provided at the air outlet 20, which may mean that the ozone removal filter assembly 48 is located inside the air outlet 20, or it may mean that the ozone removal filter assembly 48 is located on the inside or outside of the air outlet 20, as long as the air outlet 20 can be covered, so that the air passing through the deodorizing element 16 passes through the ozone removal filter assembly 48 before being discharged from the air outlet 20.

[0068] The deozonation filter assembly 48 is detachably connected to the shell 12, so that the deozonation filter assembly 48 can be removed from the shell 12 for cleaning or replacement after being used for a period of time, thereby avoiding the problem that the deozonation effect of the deozonation filter assembly 48 deteriorates after being used for a period of time, and ensuring the deozonation effect of the deodorization device 10.

[0069] The specific method of detachable connection between the ozone removal filter assembly 48 and the shell 12 is not limited, such as a snap connection or a magnetic connection. The snap connection and magnetic connection methods make it easy to install the ozone removal filter assembly 48 on the shell 12 or remove it from the shell 12, and facilitate the disassembly and assembly of the ozone removal filter assembly 48.

[0070] In this embodiment, the deozonation filter assembly 48 is connected to the shell 12 by a snap connection. The deozonation filter assembly 48 is provided with a buckle body, and the shell 12 is correspondingly provided with a buckle hole. The deozonation filter assembly 48 can form a snap connection effect through the cooperation of the buckle body and the buckle hole.

[0071] In other embodiments, buckle holes may be provided on the deozonation filter assembly 48 and buckle bodies may be correspondingly provided on the housing 12 , which can also form a snap-fit connection between the deozonation filter assembly 48 and the housing 12 .

[0072] It can be understood that in order to facilitate the installation of the ozone removal filter assembly 48, a positioning structure can be set between the ozone removal filter assembly 48 and the shell 12. For example, a positioning column is set on one of them and a corresponding positioning hole is set on the other. The cooperation between the positioning column and the positioning hole can form a positioning effect during the installation process of the ozone removal filter assembly 48, thereby assisting the installation of the ozone removal filter assembly 48.

[0073] In this embodiment, an operating portion 42 is provided on the outside of the ozone removal filter assembly 48. The operating portion 42 protrudes from the outer surface of the ozone removal filter assembly 48. During the installation and disassembly of the ozone removal filter assembly 48, the operating portion 42 can be grasped by hand to facilitate the installation and disassembly of the ozone removal filter assembly 48.

[0074] It is understandable that the operating portion 42 may be a bump protruding from the surface of the deozonizing filter assembly 48 , or a handle fixedly mounted on the outside of the deozonizing filter assembly 48 .

[0075] In other embodiments, the operating portion 42 is recessed in the outer surface of the ozone removal filter assembly 48 to form a gripping position so that a finger can be inserted into the operating portion 42 and hooked on the operating portion 42, which also facilitates the installation and removal of the ozone removal filter assembly 48.

[0076] Preferably, two operating portions 42 are provided on the outer surface of the ozone removal filter assembly 48 , and the two operating portions 42 are spaced apart from each other so as to facilitate operation with both hands.

[0077] The structure of the operating portion 42 on the outside of the deozonizing filter assembly 48 and the operating portion 42 on the outside of the dustproof filter assembly 40 may be the same or different.

[0078] The ozone filter assembly 48 includes an air outlet grille 50 and an ozone filter 52. The air outlet grille 50 is detachably connected to the housing 12 and has multiple grille holes for air discharge. The ozone filter 52 is located inside the air outlet grille 50 to protect the ozone filter 52. After the air outlet grille 50 is removed from the housing 12, the ozone filter 52 can be removed for cleaning or replacement.

[0079] In this embodiment, the air outlet grille 50 is snap-connected or magnetically connected to the shell 12 to form a detachable connection with the shell 12. The operating part 42 on the ozone removal filter assembly 48 is arranged on the outside of the air outlet grille 50 to facilitate the installation and disassembly of the air outlet grille 50.

[0080] It can be understood that the deozonation filter 52 can be fixed on the inner side of the air outlet grille 50, or it can be installed inside the shell 12 or the fan 14. In this embodiment, the deozonation filter 52 is located in the guide portion 38 of the volute 24 and is arranged at one end of the guide portion 38 close to the air outlet 20. The deodorizing element 16 is arranged close to the deozonation filter 52 so as to decompose the ozone generated by the deodorizing element 16 into oxygen in a timely manner.

[0081] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
