Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted air purification equipment, and in particular to a photocatalyst vehicle-mounted lamp for rail transit. Background Art

[0002] With the rapid development of domestic high-speed railways and subways, people are paying more and more attention to the air quality in the car. In order to provide a safe and comfortable riding environment, they usually choose to use car air purification products to purify the air in the car.

[0003] At present, subways and high-speed railways mainly use air-conditioning systems to achieve air circulation. The filters of air-conditioning systems and fresh air systems can only absorb some particles and dust, and cannot further purify harmful substances and pollutants in the air. Therefore, the air purification effect needs to be further improved. Utility Model Content

[0004] In order to enhance the air purification effect, the present application provides a photocatalyst vehicle-mounted lamp for rail transit.

[0005] The photocatalyst vehicle-mounted lamp for rail transit provided in this application adopts the following technical solution:

[0006] A photocatalyst vehicle-mounted lamp for rail transit, comprising a lampshade, a light-emitting component and an exhaust component, wherein the light-emitting component is arranged in the lampshade, the inner wall of the lampshade is arranged in a wavy shape, and a first photocatalyst coating is arranged on the inner wall of the lampshade, the exhaust component is arranged at one end of the lampshade, an air inlet or an air outlet of the exhaust component is located on the inner side of the lampshade, and a vent is opened on the end of the lampshade away from the exhaust component.

[0007] By adopting the above technical scheme, the air in the car is sucked into the lampshade after the exhaust part is started. Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, producing free hydroxyl radicals and active oxygen with extremely strong oxidizing ability. It has a strong photooxidation-reduction function, and catalytically reduces harmful positions such as benzene and formaldehyde in the air into hydroxyl free radicals. The bacteria and viruses in the air will be inactivated by the hydroxyl free radicals that destroy the nucleic acid and finally reduced to water. The purified air is then discharged, thereby playing a role in sterilization and removing harmful gases. Therefore, it can enhance the air purification effect while also having a lighting effect.

[0008] Optionally, the lampshade is in the shape of an elongated strip, and a plurality of the light-emitting members are provided, and the light-emitting members are arranged at intervals along the length direction of the lampshade.

[0009] By adopting the above technical solution, the long strip lamp body structure is more suitable for use in subways and high-speed railways, which helps to enhance the lighting effect. It can also prolong the residence time of air in the lampshade, thereby prolonging the air purification time, which helps to enhance the purification effect.

[0010] Optionally, a filter layer is provided on the lampshade.

[0011] By adopting the above technical solution, the filter layer can filter out impurities such as dust in the air, which helps to enhance the air purification effect.

[0012] Optionally, the filter layer is located on the air inlet side of the lampshade.

[0013] By adopting the above technical solution, the filter layer can block impurities such as dust in the air, reduce the dust entering the lampshade, thereby reducing the dust accumulated on the surface of the light-emitting component, which helps to ensure the lighting effect of the light-emitting component.

[0014] Optionally, a hanging rope is provided on the lampshade.

[0015] By adopting the above technical solution, the lampshade can be quickly installed at a desired position.

[0016] Optionally, a baffle is provided on the inner wall of the lampshade, and a plurality of the baffles are provided, and the plurality of the baffles are arranged in a staggered manner.

[0017] By adopting the above technical solution, the staggered baffles can block the air flowing into the lampshade, so that the air can flow along the gaps between the baffles, thereby extending the air flow path, helping to extend the air purification time, and thus enhancing the purification effect.

[0018] Optionally, the blocking piece is transparent.

[0019] By adopting the above technical solution, the influence of the setting of the baffle on the illumination can be reduced, which helps to ensure the reaction effect of the photocatalyst.

[0020] Optionally, a second photocatalyst coating is provided on the baffle.

[0021] By adopting the above technical solution, the second photocatalyst coating will also react after being exposed to light, thereby releasing free hydroxyl groups and active oxygen to purify the air.

[0022] Optionally, a bracket is detachably connected inside the lampshade, and the blocking piece is fixedly connected to the bracket.

[0023] By adopting the above technical solution, the baffle can be detachably arranged, so after the baffle has been working for a long time, the baffle can be taken out and then re-coated with the photocatalyst coating, which helps to ensure the air purification effect.

[0024] Optionally, the bracket is slidably disposed on the lampshade, a first magnetic component is disposed on the lampshade, and a second magnetic component for attracting the first magnetic component is disposed on the bracket.

[0025] By adopting the above technical solution, after the bracket is installed in the lampshade, the first magnetic member and the second magnetic member are attracted to each other, thereby fixing the bracket. Therefore, the fixing process is simple and helps to improve the stability of the baffle during operation.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The exhaust part draws the air in the car into the lampshade, and then the light emitted by the light-emitting part in the lampshade shines on the first photocatalyst coating. The photocatalyst reacts and releases free hydroxyl radicals and active oxygen with strong redox ability, thereby purifying harmful substances in the air, thus helping to improve the air purification effect.

[0028] 2. The lamp body structure is arranged in a long strip shape, and there are multiple light-emitting parts arranged at intervals, so it is more suitable for use in high-speed rail and subway carriages, which helps to enhance the lighting and air purification effects.

[0029] 3. The setting of the baffle can block the air, thereby preventing the air from flowing in a straight line, helping to extend the air flow path, thereby extending the air purification treatment time, and helping to enhance the air purification effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Example 1

[0038] The present application embodiment discloses a photocatalyst vehicle-mounted lamp for rail transit. Figure 1 and Figure 2 The photocatalyst vehicle-mounted lamp for rail transit includes a lampshade 1, a light-emitting member 2 and an exhaust member. The lampshade 1 is arranged in a long strip shape, and a cavity is arranged inside the lampshade 1. The light-emitting member 2 is fixedly installed in the cover body, and a plurality of light-emitting members 2 are arranged, and are arranged at intervals along the length direction of the lampshade 1; the light-emitting member 2 includes a mounting plate 21 and an LED light strip 22. The mounting plate 21 is fixedly connected to the inner wall at the top of the lampshade 1, and the mounting plate 21 is arranged horizontally; the LED light strip 22 is fixedly connected to the side of the mounting plate 21 close to the inside of the lampshade 1, so that the light emitted by the LED light strip 22 can illuminate the inner wall of the lampshade 1. A power supply 11 is fixedly connected to the outer wall at the top of the lampshade 1, and the power supply 11 is electrically connected to the LED light strip 22 through a wire, so as to supply power to the LED light strip 22.

[0039] Reference Figure 3 The inner wall at the bottom of the lampshade 1 is arranged to be wavy, and the wavy wall surface is coated with a first photocatalyst coating 4. After the photocatalyst is sprayed, a layer of transparent nano titanium dioxide film will be formed after natural drying. The titanium dioxide nanoparticles in the film produce hydroxyl radicals under the irradiation of light. Such free radicals can non-selectively degrade pollutants in the air, kill bacteria and mold, and release negative oxygen ions, thereby purifying the air.

[0040] Reference Figure 1 and Figure 2 , one end of the lampshade 1 is closed, and the other end of the lampshade 1 is provided with a vent 12; the air extraction member includes a fan 3, which is fixedly connected to the closed end of the lampshade 1, the air inlet of the fan 3 is located inside the lampshade 1, and the air outlet of the fan 3 is located outside the lampshade 1. Therefore, after the fan 3 is started, the air in the compartment can be drawn into the lampshade 1 from the vent 12, and then the air flows along the length direction of the lampshade 1, and is discharged to the outside of the lampshade 1 after being purified, thereby purifying the air in the compartment.

[0041] Furthermore, a filter layer 5 is installed on the wall of the lampshade 1 at the vent 12, and the filter layer 5 is a washed cotton filter plate; therefore, the air entering the lampshade 1 needs to first flow through the filter layer 5, and the filter layer 5 filters out impurities such as dust in the air. The filtered air then enters the lampshade 1 for purification, thereby reducing the dust accumulated on the surface of the light-emitting component 2.

[0042] The lampshade 1 is also provided with a hanging rope 6, and two hanging ropes 6 are provided and are respectively located at the two ends of the lampshade 1. One end of the hanging rope 6 is fixedly connected to the inner wall at the top of the lampshade 1, and the other end of the hanging rope 6 is fixedly connected to a lobster buckle. An escape hole 13 is provided on the top wall of the lampshade 1 for the hanging rope 6 and the lobster buckle to pass through. When installing the lamp, the end of the hanging rope 6 provided with the lobster buckle is passed through the escape hole 13, and the lobster buckle is hung at the desired position to complete the installation of the lamp, and the installation process is simple.

[0043] Further, in the initial state, the lobster clasp is bonded to the inner wall of the top of the lampshade 1, thereby preventing the lobster clasp and the LED light strip 22 from colliding during transportation. When installation is required, the lobster clasp is removed and then hung.

[0044] The implementation principle of Example 1 is as follows: the light emitted by the light-emitting element 2 is irradiated on the first photocatalyst coating 4, the photocatalyst reacts and releases free radicals; then the fan 3 is started, and the fan 3 draws air into the car compartment; the air first flows through the filter layer 5, and the filter layer 5 filters out dust and other impurities in the air, and then the filtered air flows into the lampshade 1; then the air flows from the end where the vent 12 is located to the end close to the fan 3, and during the air flow, the air combines with the free radicals released by the photocatalyst, and the free radicals degrade the pollutants in the air and kill bacteria and mold, thereby purifying the air; then the purified air is discharged into the car compartment.

[0045] Example 2

[0046] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that a baffle 7 is provided on the inner wall of the bottom of the lampshade 1 in this embodiment; the baffle 7 is made of a transparent plastic material, and the surface of the baffle 7 is perpendicular to the length direction of the lampshade 1; a plurality of baffles 7 are provided, and are arranged at intervals along the length direction of the lampshade 1; the plurality of baffles 7 are arranged in a staggered manner, so that the baffles 7 can block the air flowing into the lampshade 1, thereby changing the flow path of the air, prolonging the time of air purification treatment, and helping to enhance the purification effect.

[0047] Furthermore, both sides of the baffle 7 are coated with a second photocatalyst coating 71, so that the amount of photocatalyst can be increased, thereby enhancing the air purification effect.

[0048] In order to facilitate regular maintenance of the baffle 7, the baffle 7 and the lampshade 1 are detachably connected. A guide rod 14 is vertically fixedly connected to the inner wall of the lampshade 1 near the fan 3. Two guide rods 14 are provided and are arranged in parallel at intervals. A bracket 8 is slidably provided on the guide rod 14 along its length direction. The bracket 8 is provided with a guide hole 81 adapted to the guide rod 14. The baffle 7 is fixedly connected to the bracket 8. The inner wall of the lampshade 1 near the fan 3 is fixedly connected to the inner wall of the lampshade 1 near the fan 3.

[0049] The first magnetic member 9 is connected, and the end of the bracket 8 is fixedly connected with the second magnetic member 10; the second magnetic member 10 and the first magnetic member 9 are both magnets, and the magnetic poles of the second magnetic member 10 and the first magnetic member 9 on the side close to each other are in opposite directions. Therefore, after the bracket 8 is installed, the second magnetic member 10 can be attracted to the first magnetic member 9, thereby fixing the bracket 8 and improving the stability of the baffle 7 during operation. In order to facilitate the installation of the bracket 8 and the baffle 7 into the lampshade 1, the filter layer 5 and the wall surface at the end of the lampshade 1 are detachably connected by bolts.

[0050] The implementation principle of Example 2 is as follows: the bracket 8 is installed in the lampshade 1, and the first magnetic member 9 and the second magnetic member 10 are attracted to each other, so as to fix the bracket 8 and the baffle 7 on the bracket 8 in the lampshade 1. Then, the fan 3 is started, and the fan 3 draws air into the lampshade 1. When the air encounters the baffle 7 during the flow, the baffle 7 will block the air and change the flow path of the air, thereby prolonging the residence time of the air in the lampshade 1 and enhancing the air purification effect.

[0051] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
