[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Please refer to Figures 1 to 4 As shown in the embodiment of this utility model, a deodorizing device is provided, including a mounting housing 1, a purification module 2, and a cover plate 3. The mounting housing 1 is used to install at the ventilation opening of a refrigerator. The mounting housing 1 has a ventilation channel 11 for air to pass through. The purification module 2 is disposed in the ventilation channel 11 and is used to purify the air when the air passes through the ventilation channel 11. The cover plate 3 is covered on the opening of the ventilation channel 11 facing the inside of the refrigerator. The cover plate 3 has a ventilation structure 31 for air to pass through. The cover plate 3 is detachably connected to the mounting housing 1.

[0034] Specifically, the mounting housing 1 refers to a shell-shaped component with a certain internal space, and for ease of installation, the mounting housing 1 can be cylindrical. The ventilation channel 11 refers to a channel structure of a certain length, with openings at both ends. The purification module 2 refers to a component or assembly capable of purifying the air, which can be achieved through filtration, adsorption, UV sterilization, or photocatalytic catalysis. Air purification and odor removal are achieved as air flows through the purification module 2. The cover plate 3 refers to a plate-shaped component with a certain area, and can be detached and connected to the mounting housing 1 via snap-fit, sleeve, or threaded connection. The ventilation structure 31 refers to a structure that allows gas to pass through; the ventilation structure 31 can be a mesh structure, in which case the cover plate 3 can be a filter screen. The ventilation structure 31 can also consist of multiple ventilation holes evenly distributed on the cover plate 3.

[0035] The deodorizing device provided in this embodiment of the invention has a purification module 2 installed in the ventilation channel 11 on the mounting housing 1. A cover plate 3 is detachably installed at the opening of the ventilation channel 11 facing the inside of the refrigerator, and the cover plate 3 also has a ventilation structure 31. In use, the mounting housing 1 can be installed at the refrigerator's ventilation opening. When the refrigerator's internal air circulation occurs, air passes through the ventilation channel 11. As the air passes through the purification module 2, it is purified, removing odor molecules and bacteria from the air vents. Compared with existing deodorizing devices, by removing the cover plate 3 and placing it over the opening of the ventilation channel 11, the cover plate 3 can be removed from the mounting housing 1 when the purification module 2 needs to be replaced after prolonged use. The purification module 2 can then be removed from the mounting housing 1, and the cover plate 3 can be reinstalled at the opening of the ventilation channel 11 when a new purification module 2 is replaced. This makes replacing the purification module 2 more convenient and ensures that the deodorizing device's adsorption effect remains optimal for a long time.

[0036] In an optional embodiment, please refer to Figure 2The cover plate 3 can be a filter screen, and the ventilation structure 31 on the cover plate 3 is the filter screen. In this embodiment, by setting the cover plate 3 as a filter screen, it can not only affect the air entering the ventilation channel 11, but also filter the air entering the ventilation channel 11, so as to prevent dust or other impurities from entering the ventilation channel 11.

[0037] In one embodiment, see Figure 1 and Figure 2 A connecting structure 4 is provided between the purification module 2 and the cover plate 3, allowing the purification module 2 to be detachably connected to the cover plate 3 via the connecting structure 4. Specifically, the connecting structure 4 refers to a component or part that can connect two objects. The connecting structure 4 can be a snap-fit ​​structure, a plug-in structure, or a fastener connection structure to achieve a detachable connection between the two components. In this embodiment, by providing the connecting structure 4 between the purification module 2 and the cover plate 3, the purification module 2 is connected to the cover plate 3 via the connecting structure 4, and the cover plate 3 fixes the position of the purification module 2, making the installation of the purification module 2 safer and more stable. Furthermore, the purification module 2 can be pulled out of the ventilation channel 11 while the cover plate 3 is being removed from the mounting housing 1, making the disassembly of the purification module 2 more convenient.

[0038] Furthermore, when installing the purification module 2, the purification module 2 can first be connected to the cover plate 3 through the connecting structure 4, and then the cover plate 3 can be connected to the mounting housing 1. At the same time, the purification module 2 can be inserted into the ventilation channel 11, and the installation is completed after the cover plate 3 is connected to the mounting housing 1, making the installation of the purification module 2 more convenient.

[0039] In one embodiment, see Figure 2 and Figure 3The connecting structure 4 includes a limiting blocking part 41 and a snap-fit ​​rotating piece 42. The limiting blocking part 41 is disposed on the side of the cover plate 3, and the limiting blocking part 41 and the side of the cover plate 3 are spaced apart from each other. The snap-fit ​​rotating piece 42 is disposed on the outside of the purification module 2 and is used to snap into the gap between the limiting blocking part 41 and the cover plate 3. Specifically, the limiting blocking part 41 refers to a component with a certain height. The limiting blocking part 41 can be strip-shaped or plate-shaped, etc., and the limiting blocking part 41 can be integrally formed with the cover plate 3. The snap-fit ​​rotating piece 42 refers to a plate-shaped structure with a certain area. The snap-fit ​​rotating piece 42 can be integrally formed with the outer wall of the purification module 2. In this embodiment, by providing a limiting blocking part 41 on the cover plate 3 and spaced apart from the side of the cover plate 3, a limiting slot is formed between the limiting blocking part 41 and the cover plate 3. At the same time, the purification module 2 is also provided with a snap-fit ​​rotating piece 42. When the purification module 2 and the cover plate 3 need to be connected to each other, the snap-fit ​​rotating piece 42 can be snapped into the gap between the limiting blocking part 41 and the cover plate 3, that is, snapped into the limiting slot between the limiting blocking part 41 and the cover plate 3, making the connection between the purification module 2 and the cover plate 3 more convenient and the connection more secure.

[0040] In an optional embodiment, please refer to Figure 3 The purification module 2 can be cylindrical in shape, and the locking tabs 42 can be spaced apart around the axis of the purification module 2. Simultaneously, the limiting and blocking part 41 can be set along a ring-shaped contour on the cover plate 3, and the limiting and blocking part 41 also has a clearance opening 43. When the purification module 2 and the cover plate 3 need to be connected, the purification module 2 can be moved closer to the cover plate 3, allowing the locking tabs 42 to pass through the clearance opening 43 and enter the position contacting the cover plate 3. Then, by rotating the purification module 2, the locking tabs 42 rotate together with the purification module 2 to the gap between the limiting and blocking part 41 and the cover plate 3, thereby achieving mutual locking between the locking tabs 42 and the limiting and blocking part 41. When the purification module 2 and the cover plate 3 need to be separated, the purification module 2 and the locking tabs 42 can be rotated in the opposite direction, causing the locking tabs 42 to rotate to the clearance opening 43. Then, the purification module 2 can be moved away from the cover plate 3 to achieve disassembly, making the disassembly and installation of the purification module 2 and the cover plate 3 more convenient.

[0041] In one embodiment, see Figure 1 and Figure 2The cover plate 3 and the mounting housing 1 are connected by an installation structure 5, through which the cover plate 3 is detachably connected to the mounting housing 1. Specifically, the installation structure 5 refers to a structure or component that allows for the detachable connection of two objects. The installation structure 5 can achieve the detachable connection of the two objects through methods such as plugging, snapping, or threading. For example, an elastic buckle can be provided on the mounting housing 1, and an installation groove can be provided on the cover plate 3. The detachable connection between the cover plate 3 and the mounting housing 1 is achieved through the snapping engagement of the elastic buckle. In this embodiment, the installation structure 5 between the cover plate 3 and the mounting housing 1 makes the detachable connection between the cover plate 3 and the mounting housing 1 more convenient.

[0042] In one embodiment, see Figure 2 The mounting structure 5 includes a connecting cylinder 51, which is disposed on the side of the cover plate 3 facing the mounting housing 1. The connecting cylinder 51 is used to fit over the outside of the mounting housing 1, and its inner wall is threadedly connected to the outer wall of the mounting housing 1. Specifically, the connecting cylinder 51 refers to a cylindrical structure with a certain length. One end of the connecting cylinder 51 is connected to the side of the cover plate 3, and the other end of the connecting cylinder 51 extends away from the cover plate 3. The connecting cylinder 51 can be integrally formed with the cover plate 3, for example, by injection molding. The connecting cylinder 51 can also be a separate component, connected to the cover plate 3 by means of bonding, welding, or fasteners. In this embodiment, by providing the connecting cylinder 51 on the side of the cover plate 3 facing the mounting housing 1, when the cover plate 3 needs to be connected to the mounting housing 1, the connecting cylinder 51 can be fitted over the outside of the mounting housing 1, and the connecting cylinder 51 can be fixed to the mounting housing 1 by threading its inner wall to the outer wall of the mounting housing 1. By incorporating a connecting cylinder 51 and fitting it onto the outside of the mounting housing 1, the contact area between the cover plate 3 and the mounting housing 1 is increased. Simultaneously, the inner wall of the connecting cylinder 51 is threaded to the outer wall of the mounting housing 1, allowing for connection or disassembly simply by rotating the cover plate 3 relative to the mounting housing 1, thus making the installation and disassembly of the mounting housing 1 and the cover plate 3 more convenient.

[0043] In one embodiment, see Figure 1 and Figure 2A baffle plate 6 is also provided on the side of the cover plate 3 facing away from the mounting housing 1, and the baffle plate 6 is spaced apart from the cover plate 3. Specifically, the baffle plate 6 refers to a plate-like structure with a certain area, and the shape of the baffle plate 6 can be adapted to the shape of the cover plate 3. In this embodiment, by providing the baffle plate 6 at intervals on the side of the cover plate 3 facing away from the mounting housing 1, a gap is formed between the baffle plate 6 and the cover plate 3 to allow airflow to pass through, which slows down the speed of the airflow entering the ventilation channel 11, and at the same time prolongs the airflow path, increasing the interaction time between the air and the purification module 2. This provides conditions for the purification module 2 to fully filter foreign objects or odors in the airflow, thereby improving the purification effect of the deodorization device.

[0044] In an optional embodiment, please refer to Figure 2 Multiple insertion cylinders 8 are provided on the side of the cover plate 3, and multiple insertion posts 7 are provided on the side of the barrier baffle 6. The positions of the insertion posts 7 match the positions of the insertion cylinders 8. Specifically, the insertion cylinder 8 refers to a cylindrical structure with a certain height, one end of which is connected to the cover plate 3, and the other end has an opening. The insertion post 7 refers to a columnar component with a certain length, and the size of the insertion post 7 is adapted to the internal size of the insertion cylinder 8. In this embodiment, when the barrier baffle 6 is connected to the cover plate 3, the insertion posts 7 can be inserted into the insertion cylinders 8 to connect the cover plate 3 and the barrier baffle 6. At the same time, the support of the insertion posts 7 can also make the cover plate 3 and the barrier baffle 6 spaced apart, making the installation of both more convenient.

[0045] In one embodiment, see Figure 2 The purification module 2 includes a deodorizing housing 21, an adsorption component 22, and a discharge component 23. The deodorizing housing 21 has a receiving space, an installation port 211, and a base plate 212 opposite to the installation port 211. The adsorption component 22 is located in the receiving space. At least a portion of the discharge component 23 is located between the adsorption component 22 and the base plate 212. At least another portion of the discharge component 23 extends from the installation port 211 to the outside of the deodorizing housing 21.

[0046] Specifically, the deodorizing housing 21 refers to a shell-like structure with a certain amount of accommodating space, and its shape is generally cylindrical. The mounting port 211 refers to an opening structure with a certain area, which may be located at the end of the deodorizing housing 21 when it is cylindrical. The base plate 212 refers to a side wall opposite to the mounting port 211, and it may be located at the other end of the deodorizing housing 21. The base plate 212 may be integrally formed with the deodorizing housing 21, and may have ventilation holes. Alternatively, the base plate 212 may be a separate component; for example, it may be a filter plate, attached to the end opening of the deodorizing housing 21 by snap-fit, fastener connection, or insertion.

[0047] The adsorption component 22 refers to a part composed of adsorption material. The shape of the adsorption component 22 is adapted to the internal shape of the deodorizing shell 21. For example, when the deodorizing shell 21 is columnar, the adsorption component 22 can also be columnar, or it can be a columnar structure composed of multiple plates of the same shape stacked together. The materials constituting the adsorption component 22 can be activated carbon, molecular sieves, or silica gel, etc. The discharge component 23 refers to a part with a certain volume. The discharge component 23 can be plate-shaped or ring-shaped, etc., and the main body shape of the discharge component 23 can be adapted to the internal shape of the deodorizing shell 21.

[0048] In this embodiment, the adsorption component 22 is installed inside the deodorizing housing 21 through an opening structure, forming an integral modular structure with the deodorizing housing 21, which facilitates the installation and production of the adsorption component 22. The deodorizing housing 21 can also be connected to the cover plate 3, with the cover plate 3 blocking and covering the installation opening 211 of the deodorizing housing 21, ensuring the stability of the adsorption component 22 after installation. Simultaneously, a discharge component 23 is also provided inside the deodorizing housing 21. At least a portion of the discharge component 23 is located between the adsorption component 22 and the bottom plate 212, and at least another portion of the discharge component 23 extends from the installation opening 211 to the outside of the deodorizing housing 21. When replacing the adsorption component 22, the cover plate 3 can first be removed from the deodorizing housing 21, for example, by rotating the cover plate 3 to separate it from the deodorizing housing 21. Then, by pulling the part of the discharge component 23 that extends out of the deodorizing housing 21, the discharge component 23 is moved outward as a whole. The adsorption component 22 is pushed out of the deodorizing housing 21 through the part of the discharge component 23 located between the adsorption component 22 and the bottom plate 212. After installing the new adsorption component 22 into the deodorizing housing 21, the cover plate 3 can be reinstalled at the installation port 211, making the replacement of the adsorption component 22 more convenient and quick.

[0049] In one embodiment, see Figure 4The discharge assembly 23 includes a discharge ring 231 and a pull handle 232. The discharge ring 231 is located between the adsorption assembly 22 and the base plate 212. One end of the pull handle 232 is connected to the discharge ring 231, and the other end extends to the outside of the deodorizing housing 21 through the mounting port 211. Specifically, the discharge ring 231 refers to a ring-shaped component of a certain size, and the size and shape of the discharge ring 231 are adapted to the size and shape of the adsorption assembly 22. The pull handle 232 refers to a component of a certain length, and the pull handle 232 can be a component with a certain degree of flexibility. In this embodiment, the discharge assembly 23 is divided into two parts: a discharge ring 231 and a pull handle 232. The discharge ring 231 is positioned between the adsorption assembly 22 and the base plate 212. One end of the pull handle 232 is connected to the discharge ring 231, and the other end extends out of the deodorizing housing 21 through the mounting port 211. Pulling the handle 232 drives the discharge ring 231 to push the adsorption assembly 22 out of the deodorizing housing 21. This allows the adsorption assembly 22 to be pushed without obstructing the airflow within the deodorizing housing 21.

[0050] In one embodiment, see Figure 4 The adsorption component 22 includes activated carbon plates 221 and elastic elements 222. Multiple activated carbon plates 221 and multiple elastic elements 222 are arranged alternately along the depth direction of the deodorizing housing 21. Specifically, the activated carbon plate 221 refers to a plate-like structure made of activated carbon, and its shape generally matches the internal shape of the deodorizing housing 21. The elastic element 222 refers to a component with a certain elasticity, such as a spring or a rubber sheet with holes. In this embodiment, by arranging multiple activated carbon plates 221 sequentially along the depth direction of the deodorizing housing 21, the interaction time between air and the activated carbon plates 221 can be increased while ensuring smooth airflow, thereby improving the adsorption effect of the adsorption component 22. Meanwhile, elastic elements 222 are provided between two adjacent activated carbon plates 221, which can buffer and position the activated carbon plates 221, preventing the activated carbon plates 221 from shaking due to pressure difference when the refrigerator door is opened and closed, making the installation of the activated carbon plates 221 more stable and improving the safety of the adsorption component 22.

[0051] In an optional embodiment, please refer to Figure 4The elastic element 222 includes a helical spring sheet. Specifically, a helical spring sheet is a mechanical element that achieves elastic deformation through a helical structure, and can be made of metal sheet or composite material. In this embodiment, the elastic element 222 adopts a helical spring sheet, which not only buffers and positions the activated carbon plate 221, but also reduces the space occupied by the elastic element 222. This makes the overall structure of the adsorption assembly 22 more compact, and also reduces the overall production cost of the adsorption assembly 22.

[0052] Secondly, this utility model also provides a refrigerator 200, please refer to [link / reference needed]. Figure 5 The deodorizing device 100 includes any of the above-mentioned features. The mounting housing 1 can be installed at the air inlet or air outlet of the circulating air duct in the refrigerator 200, depending on the actual situation. One end of the ventilation channel 11 on the mounting housing 1 is located inside the refrigerator 200 in the space used for storing food, and the cover 3 is detachably installed at this end. It is understood that the beneficial effects of the second aspect described above can be found in the relevant description in the first aspect above, and will not be repeated here.

[0053] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way.
