Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a deodorization device. Background Technology

[0002] With the rapid development of high-speed rail, passengers' demands for travel comfort are constantly increasing, and the problem of toilet odor has become one of the key factors affecting the quality of high-speed rail service. Due to their relatively small space, high frequency of use, and limited ventilation, train toilets are prone to accumulating foul-smelling gases such as ammonia, hydrogen sulfide, and volatile organic compounds, seriously affecting passengers' travel experience.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art: Most existing solutions use negative pressure suction systems and forced ventilation through roof fans, but these only expel the odor rather than remove it. During peak hours, the odor may seep back into the car, resulting in poor deodorization.

[0004] Therefore, there is an urgent need for a deodorization device with a compact structure that can adapt to small installation spaces while removing malodorous gases. Utility Model Content

[0005] In view of this, the present invention provides a deodorizing device that can remove malodorous gases and improve the deodorizing effect.

[0006] This application provides a deodorization device, including a housing and a fan, a deodorization component, and a control component located within the housing. The housing is provided with an air inlet and an air outlet. The fan drives external gas to enter the housing through the air inlet and flow towards the air outlet. The deodorization component is located between the fan and the air outlet and is located on the side of the fan facing the air outlet direction. The control component is electrically connected to the fan and the deodorization component, and is located on the side of the fan and / or the deodorization component perpendicular to the air outlet direction. The deodorization component includes a plasma tube and a catalytic filter arranged along the air outlet direction, with the catalytic filter located between the plasma tube and the exhaust port.

[0007] Compared with the prior art, the deodorization device provided by this utility model has at least the following beneficial effects: The deodorization device provided by this utility model has a fan and deodorization components arranged along the air outlet direction, while the control component is located on the side perpendicular to the air outlet direction, where the fan and / or the deodorization component are arranged in different directions. This arrangement of the fan, deodorization component, and control component inside the housing makes full use of the internal space, resulting in a more compact internal structure and a smaller overall size, making it suitable for installations with limited space. The deodorization component includes a plasma tube and a catalytic filter. The plasma tube reacts chemically with the passing gas, destroying the molecular structure of the odor and thus removing it. The catalytic filter decomposes the secondary products generated during the odor removal process by the plasma tube, converting them into harmless small molecules, effectively ensuring the cleanliness and safety of the exhaust air. This prevents air pollution from the exhaust vent, resulting in a deodorization device that balances compact structure with effective odor removal, thus improving the deodorization effect.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0011] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0012] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0013] Please see Figures 1 to 5 This utility model provides a deodorizing device 100, which can be used in rail transit vehicles, such as the toilets of high-speed trains, to remove odors and improve the passenger experience. The deodorizing device 100 includes a housing 10, a fan 12, a deodorizing component 14, and a control component 16. The fan 12, the deodorizing component 14, and the control component 16 are installed inside the housing 10. The housing 10 has an air inlet 18 and an exhaust outlet 20. The fan 12 drives external gas to enter the housing 10 through the air inlet 18 and flow towards the exhaust outlet 20. The deodorizing component 14 is located between the fan 12 and the exhaust outlet 20, so that the airflow passes through the deodorizing component 14 as it flows from the fan 12 to the exhaust outlet 20. The deodorizing component 14 removes odor molecules from the airflow. The control component 16 is electrically connected to the fan 12 and the deodorizing component 14 to control their operation.

[0014] The fan 12 has an air inlet 22 and an air outlet 24 that are interconnected. The air inlet 22 is connected to the air intake hole 18 on the housing 10, and the air outlet 24 is connected to the exhaust hole 20 on the housing 10. The fan 12 drives the airflow to pass sequentially through the air intake hole 18, the air inlet 22, the air outlet 24, and the exhaust hole 20. The direction of airflow when it is blown out of the air outlet 24 of the fan 12 is the air outlet direction of the fan 12. In this embodiment, the air outlet 24 of the fan 12 faces the exhaust hole 20, and the air outlet direction is the direction from the air outlet 24 to the exhaust hole 20.

[0015] The deodorizing component 14 is located on the side of the fan 12 facing the air outlet direction X, meaning the fan 12 and the deodorizing component 14 are arranged along the air outlet direction X. The control component 16 is located on the side of the fan 12 and / or the deodorizing component 14 perpendicular to the air outlet direction X. The fan 12, the deodorizing component 14, and the control component 16 are arranged in different directions within the housing 10, which makes full use of the internal space of the housing 10, making the internal structure of the housing 10 more compact. This helps to reduce the overall volume of the deodorizing device 100, allowing it to be used in scenarios with relatively limited installation space, such as high-speed rail restrooms.

[0016] In one alternative example, the housing 10 is rectangular, the air outlet direction X is the length direction of the rectangle, and the direction perpendicular to the air outlet direction X is the width direction of the rectangle.

[0017] The deodorization component 14 includes a plasma tube 26 and a catalytic filter 28 arranged along the air outlet direction X. The catalytic filter 28 is located between the plasma tube 26 and the exhaust port 20. That is, the plasma tube 26 is closer to the fan 12 than the catalytic filter 28, and the catalytic filter 28 is closer to the exhaust port 20 than the plasma tube 26. As the airflow flows from the fan 12 to the exhaust port 20, the airflow first passes through the plasma tube 26, then through the catalytic filter 28, and finally exits from the exhaust port 20. When the plasma tube 26 is working, it can generate ozone and free radicals. When the airflow passes through the plasma tube 26, the ozone and free radicals can chemically react with odor molecules (such as hydrogen sulfide, ammonia, and volatile organic compounds) in the airflow, oxidizing and decomposing the odor molecules and converting them into harmless small molecules such as carbon dioxide and water. This decomposes and removes odor molecules. At the same time, the plasma tube 26 can also inactivate microorganisms in the airflow, achieving a sterilization and disinfection effect. After being deodorized by the plasma tube 26, the airflow passes through the catalytic filter 28. The catalytic filter 28 catalytically decomposes residual ozone and nitrogen oxides in the airflow, removing these secondary products before the airflow is discharged from the exhaust port 20. This effectively ensures the cleanliness and safety of the discharged air, thus preventing environmental pollution. The deodorization device 100 enhances the compactness of the internal structure of the housing 10 by arranging the fan 12, deodorization component 14, and control component 16 in different directions, reducing the overall size of the product. Simultaneously, by placing the plasma tube 26 and catalytic filter 28 between the fan 12 and the exhaust port 20, odor molecules and secondary products in the airflow are decomposed and removed. This combination of compact structure and high-efficiency deodorization improves the deodorization effect.

[0018] In one embodiment, the deodorization assembly 14 further includes a mounting bracket 30 installed inside the housing 10. The mounting bracket 30 is located between the fan 12 and the exhaust port 20 and is fixed relative to the housing 10. The plasma tube 26 and the catalytic filter 28 are detachably installed to the mounting bracket 30. By providing the mounting bracket 30 for the installation of the plasma tube 26 and the catalytic filter 28, during the assembly process, the plasma tube 26 and the catalytic filter 28 can be installed on the mounting bracket 30 first, and then the mounting bracket 30 can be installed inside the housing 10. This avoids interference from other components inside the housing 10 during the installation of the plasma tube 26 and the catalytic filter 28, reducing assembly difficulty. Moreover, both the plasma tube 26 and the catalytic filter 28 can be removed from the mounting bracket 30, facilitating the later maintenance of the deodorization assembly 14.

[0019] The specific method by which the plasma tube 26 and the catalytic filter 28 are detachably connected to the mounting bracket 30 is not limited. For example, the detachable effect can be achieved by magnetic attraction, or by sliding or snap-fitting.

[0020] Optionally, the mounting bracket 30 is provided with a first mounting groove 32 and a second mounting groove 34, which are arranged at intervals along the air outlet direction X, and the first mounting groove 32 is closer to the fan 12 than the second mounting groove 34. The plasma tube 26 is slidably mounted to the first mounting groove 32 to detachably mount the plasma tube 26 on the mounting bracket 30, and the catalytic filter 28 is slidably mounted to the second mounting groove 34 to detachably mount the catalytic filter 28 on the mounting bracket 30. Plasma tube 26 is installed on mounting bracket 30 by sliding it into the first mounting slot 32, and removed from mounting bracket 30 by sliding it out of the first mounting slot 32. Similarly, catalytic filter 28 is installed on mounting bracket 30 by sliding it into the second mounting slot 34, and removed from mounting bracket 30 by sliding it out of the second mounting slot 34. Plasma tube 26 and catalytic filter 28 are installed in a modular manner on mounting bracket 30, and installation and removal are achieved by sliding. The installation and removal operation is simple, which facilitates the later maintenance of deodorization component 14, reduces the safety hazards caused by human error during maintenance, and balances convenient maintenance with operational safety. Furthermore, when the plasma tube 26 and the catalytic filter 28 are located in the first mounting groove 32 and the second mounting groove 34, the first mounting groove 32 and the second mounting groove 34 can play a certain limiting effect on the plasma tube 26 and the catalytic filter 28, so as to enhance the stability of the plasma tube 26 and the catalytic filter 28 on the mounting frame 30.

[0021] The mounting bracket 30 includes two spaced-apart opposing sides 36 extending along the air outlet direction X. The two sides 36 are arranged perpendicular to the air outlet direction X, and the plasma tube 26 and the catalytic filter 28 are located between the two sides 36. Each side 36 is provided with a first mounting groove 32 and a second mounting groove 34, and the first mounting groove 32 and the second mounting groove 34 are located on opposite sides of the two sides 36. The two first mounting grooves 32 are directly opposite each other, and the two ends of the plasma tube 26 are respectively located in the two first mounting grooves 32. The two second mounting grooves 34 are directly opposite each other, and the two ends of the catalytic filter 28 are respectively located in the two second mounting grooves 34. The two side portions 36 can limit the ends of the plasma tube 26 and the catalytic filter 28, further enhancing the stability of the plasma tube 26 and the catalytic filter 28 on the mounting bracket 30. Moreover, when the airflow flows between the two side portions 36, the two side portions 36 can prevent the airflow from diffusing to both sides. The mounting bracket 30 forms a fixed air supply channel between the two side portions 36, reducing airflow leakage and improving the air supply efficiency of the fan 12, thereby improving the deodorization efficiency of the deodorization device 100.

[0022] In an alternative example, a concave-convex structure is formed on the side 36, with the concave portion forming a corresponding mounting groove and the convex portion used to separate adjacent mounting grooves, thereby separating the plasma tube 26 and the catalytic filter 28 installed in the mounting groove.

[0023] Understandably, the side portion 36 can be a split structure, that is, it is assembled from multiple independent parts to form the first mounting groove 32 and the second mounting groove 34. Alternatively, the side portion 36 can also be a one-piece structure, and the first mounting groove 32 and the second mounting groove 34 can be formed by stamping or other means.

[0024] The mounting bracket 30 also includes a connecting portion 38 connecting the two side portions 36, making the mounting bracket 30 U-shaped. The connecting portion 38 is located at the end of the side portion 36 near the fan 12 and has a clearance hole (not shown) communicating with the air outlet 24, so that the airflow discharged from the air outlet 24 of the fan 12 can flow into the space between the two side portions 36 through the clearance hole. The end of the side portion 36 away from the connecting portion 38 forms an opening 40, which faces the exhaust port 20, preventing the mounting bracket 30 from affecting the airflow towards the exhaust port 20. The connecting portion 38 can fix the two spaced side portions 36 together, so that the two side portions 36 remain relatively fixed during the assembly of the deodorizing component 14, effectively ensuring that the first mounting groove 32 and the second mounting groove 34 on the two side portions 36 are aligned, so that the plasma tube 26 and the catalytic filter 28 can be installed onto the mounting bracket 30.

[0025] In an alternative example, the fan 12 is a centrifugal fan, which helps to reduce the overall volume of the fan 12 and the space it occupies inside the housing 10 while maintaining the same air volume. The air inlet and outlet directions of the centrifugal fan are perpendicular to each other. The air inlet 18 and the exhaust 20 are respectively located on adjacent sides of the housing 10. The fan 12 includes a volute and fan blades located inside the volute. One end of the volute with the air outlet 24 is fitted with the connecting part 38, so that the airflow flows into the air delivery channel between the two sides 36 through the clearance hole as much as possible, thereby improving the air delivery efficiency.

[0026] In one embodiment, the deodorization assembly 14 further includes an outlet filter 42 detachably mounted on the mounting bracket 30. The outlet filter 42 is located between the air outlet 24 of the fan 12 and the plasma tube 26. When the airflow flows from the air outlet 24 of the fan 12 to the plasma tube 26, it first passes through the outlet filter 42. The outlet filter 42 can filter the passing air, removing dust, particulate matter, and other impurities from the airflow, preventing impurities in the airflow from affecting the plasma tube 26. After a period of use, the outlet filter 42 can be removed from the mounting bracket 30, and the impurities on the outlet filter 42 can be cleaned, effectively ensuring that the outlet filter 42 has a good filtration effect. For example, the outlet filter 42 can be a medium-efficiency filter.

[0027] The mounting bracket 30 is provided with a filter mounting slot 44. The filter mounting slot 44, the first mounting slot 32, and the second mounting slot 34 are arranged sequentially along the air outlet direction X. The air outlet filter 42 can be slidably installed into the filter mounting slot 44, thereby arranging the air outlet filter 42, the plasma tube 26, and the catalytic filter 28 sequentially on the mounting bracket 30 along the air outlet direction X. The air outlet filter 42 can be inserted into or removed from the filter mounting slot 44 by sliding, thus realizing the installation and removal of the air outlet filter 42. The installation and removal operation is simple, and the maintenance of the edge air outlet filter 42 is easy.

[0028] Optionally, the mounting bracket 30 has filter mounting grooves 44 on both sides 36, and the two filter mounting grooves 44 are arranged opposite each other. The two ends of the air outlet filter 42 are located in the two filter mounting grooves 44 respectively, so as to enhance the stability of the air outlet filter 42 on the mounting bracket 30.

[0029] In one embodiment, the housing 10 includes a housing body 46 and a cover plate 48 covering one side of the housing body 46. The fan 12, deodorization component 14, and control component 16 are all disposed within the housing body 46. The cover plate 48 can be removed from the housing body 46, or the cover plate 48 can rotate relative to the housing body 46 to expose the fan 12, deodorization component 14, and control component 16 inside the housing body 46 for installation and maintenance. An air inlet 18 is provided on the cover plate 48, and an exhaust outlet 20 is provided on the side of the housing body 46 adjacent to the cover plate 48.

[0030] Optionally, one end of the cover plate 48 is rotatably connected to the housing body 46 via a hinge 50, and the other end is engaged with the housing body 46 via a latch 52. The latch 52 has a locked state and an unlocked state. In the locked state, the cover plate 48 and the housing body 46 remain relatively fixed, and the cover plate 48 covers the fan 12, the deodorizing component 14, and the control component 16. In the unlocked state, the cover plate 48 can rotate relative to the housing body 46 around the hinge 50 to expose the fan 12, the deodorizing component 14, and the control component 16. When maintenance is required on the fan 12, the deodorizing component 14, or the control component 16, the cover plate 48 can be opened simply by switching the latch 52 to the unlocked state, without having to remove the entire cover plate 48 from the housing body 46, making maintenance more convenient.

[0031] A filter mounting slot 44 has a filter mounting opening 54 on the side facing the cover plate 48. The outlet filter 42 can be slidably inserted into or removed from the filter mounting slot 44 through the filter mounting opening 54 to complete the installation and removal of the outlet filter 42. A first mounting slot 32 has a first mounting opening 56 on the side facing the cover plate 48. The plasma tube 26 can be slidably inserted into or removed from the first mounting slot 32 to complete the installation and removal of the plasma tube 26. A second mounting slot 34 has a second mounting opening 58 on the side facing the cover plate 48. The catalytic filter 28 can be slidably inserted into or removed from the second mounting slot 34 through the second mounting opening 58 to complete the installation and removal of the catalytic filter 28. Since the filter installation port 54, the first installation port 56 and the second installation port 58 all face the cover plate 48, after opening the cover plate 48 to expose the deodorization assembly 14, the exhaust filter 42, the plasma tube 26 and the catalytic filter 28 can be pulled out directly without having to remove the entire deodorization assembly 14 from the housing 10, making the maintenance of the exhaust filter 42, the plasma tube 26 and the catalytic filter 28 more convenient.

[0032] In one embodiment, an air inlet filter 60 is provided between the air inlet 18 of the housing 10 and the air inlet 22 of the fan 12. As outside air flows into the fan 12 through the air inlet 18, it first passes through the air inlet filter 60. After being filtered by the air inlet filter 60, dust, particulate matter, and other impurities are removed before flowing into the fan 12. After being blown out from the air outlet 24 of the fan 12, it passes through the air outlet filter 42 for further filtration, preventing impurities in the outside air from affecting the plasma tube 26 and the catalytic filter 28. For example, the air inlet filter 60 can be a pre-filter.

[0033] A sealing element 62, such as a sealing ring or sealing cotton, is provided between the air inlet filter 60 and the housing 10. The sealing element 62 surrounds the outer periphery of the air inlet hole 18 to prevent outside air from entering the housing 10 through the air inlet hole 18 and then leaking out from the gap between the air inlet filter 60 and the housing 10, so that the airflow flows to the air inlet filter 60 as much as possible to improve the overall air supply efficiency.

[0034] Optionally, the air inlet filter 60 is installed inside the cover plate 48, and the seal 62 is located between the air inlet filter 60 and the cover plate 48. In an optional example, the seal 62 is a high-density sealing cotton with an opening formed on it, which surrounds the outer periphery of the air inlet 18.

[0035] In one embodiment, the control component 16 includes an electrical control box 64 and a power supply 66 electrically connected to the electrical control box 64. The electrical control box 64 is electrically connected to the fan 12 and the plasma tube 26 to control the operation of the fan 12 and the plasma tube 26, while the power supply 66 provides electrical energy to the fan 12 and the plasma tube 26. The electrical control box 64 and the power supply 66 are arranged along the air outlet direction X, with the electrical control box 64 located on the side of the fan 12 perpendicular to the air outlet direction X, and the power supply 66 located on the side of the deodorization component 14 perpendicular to the air outlet direction X. The entire control component 16 is located on the side of the fan 12 and the deodorization component 14 perpendicular to the air outlet direction X, and the electrical control box 64 and the power supply 66 of the control component 16 are arranged along the air outlet direction X, making full use of the space inside the housing 10 to make the unevenness inside the housing 10 more compact, thereby reducing the overall size of the product. Optionally, both the electrical control box 64 and the power supply 66 are installed inside the housing 10 by screws.

[0036] The housing 10 has a through-hole 68, through which an external input cable can extend into the housing 10 to connect with the internal electrical components. Inside the housing 10 is a terminal block 70. Both the terminal block 70 and the through-hole 68 are located on the side of the fan 12 furthest from the deodorizing component 14. The terminal block 70 is located between the through-hole 68 and the electrical control box 64. After the input cable passes through the through-hole 68, it connects electrically to the terminal block 70. The electrical control box 64 is also electrically connected to the terminal block 70, thus enabling the electrical connection between the electrical control box 64 and external components. Optionally, to reduce safety hazards, a flame-retardant sleeve can be fitted over the input cable to prevent damage to the internal electrical components of the deodorizing device 100 in case of short circuits, leakage, or other faults.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
