Description

Technical Field

[0001] This utility model relates to the field of air purification equipment, and in particular to a purification structure and its vehicle-mounted lighting fixture. Background Technology

[0002] An air purifier is an electrical device used to improve indoor air quality by removing pollutants from the air through technologies such as filtration, adsorption, or decomposition. Vehicle lighting is an important component of a vehicle's lighting system, providing passengers with localized enhanced illumination for easier reading.

[0003] With the rapid development of rail transit, the air quality and lighting environment inside train carriages, as densely populated enclosed spaces, are receiving increasing attention. Air purifiers installed on the ceiling are less efficient and cannot directly purify the air around seated passengers. Therefore, to enhance the functionality of air purifiers, current products incorporate reading lights for independent use by passengers during train operation. This increases the frequency of use of the purification structure and its onboard lighting, necessitating frequent disassembly and filter replacement.

[0004] However, considering that a purification structure and its vehicle lighting are generally stable and fixed, the process of replacing the filter element is relatively complicated, which makes the cleaning process more troublesome. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a purification structure that is easy to disassemble for filter replacement, thereby reducing the difficulty of cleaning.

[0006] The second objective of this invention is to provide vehicle lighting fixtures that do not require frequent cleaning.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A purification structure, characterized in that it comprises: a mounting base, a purification body, and a fan component;

[0009] The mounting base is connected to a magnet, which is used to attract the train's housing; the mounting base is connected to a support rod, which extends along the axial direction of the mounting base.

[0010] The purification body is provided with a gas inlet, a purification chamber and a gas outlet connected in sequence. The purification body also has an installation port that communicates with the purification chamber. The purification chamber contains a filter element, which is detachably installed in the purification chamber. The mounting base is detachably installed in the installation port and the support rod abuts against the filter element to prevent the filter element from falling out of the installation port.

[0011] The fan component is installed inside the purification chamber.

[0012] Furthermore, the purification body is provided with a limiting part, which is located inside the purification chamber, and the limiting part and the support rod together clamp the filter element.

[0013] Furthermore, the filter element and the fan component are arranged sequentially at intervals along the airflow direction.

[0014] Furthermore, the purification body includes a first branch body and a second branch body, the first branch body and the second branch body are detachably connected; the fan component is disposed in the first branch body, and the filter element is disposed in the second branch body.

[0015] Furthermore, the first branch body and the second branch body are threadedly connected.

[0016] Furthermore, the mounting base is threadedly connected to the second branch body.

[0017] Furthermore, the gas inlets are provided in multiple locations, and the multiple gas inlets are distributed circumferentially around the purification body.

[0018] A vehicle-mounted lighting fixture, characterized in that it includes a lighting fixture and a purification structure; the lighting fixture has a switch; the lighting fixture is installed on the purification body, and the gas outlet faces the lighting fixture.

[0019] Furthermore, the lamp extends circumferentially around the purification body, and multiple gas outlets are provided, which are distributed at intervals around the purification body and surrounded by the lamp.

[0020] Furthermore, the lamp is detachably connected to the purification body.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. Based on the fact that the mounting base is connected to a magnet, which is used to attract the train's shell, the purification structure can be fixed by the attraction between the magnet and the train shell. This allows the device to be quickly fixed and removed without the use of tools, improving installation efficiency and applicability, and making it easy to remove for cleaning.

[0023] 2. The purification unit is equipped with a gas inlet, a purification chamber, and a gas outlet connected in sequence. The purification chamber contains a filter element, and the fan component is installed inside the purification chamber. Therefore, when the fan component is working, it can attract unpurified air to enter through the gas inlet, be filtered and purified through the filter element, and finally be discharged from the gas outlet, thus achieving the effect of air purification.

[0024] 3. Based on the fact that the filter element is detachably installed in the purification chamber, the mounting base is detachably connected to the train shell, the mounting base is detachably installed at the mounting port, and the support rod extends along the axial direction of the mounting base and abuts against the filter element, the filter element can be quickly disassembled and replaced, which also facilitates the maintenance of other internal components; at the same time, it ensures that the filter element can remain firmly in place during frequent vehicle operation, avoiding accidental dislodgement due to vibration or airflow impact.

[0025] 4. Since the lamp is installed on the purification body and the gas outlet faces the lamp, the purified air can be blown directly onto the lamp through the gas outlet, effectively removing the dust attached to the lamp surface and carrying away the heat generated when the lamp is working.

[0030] 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.

[0031] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] See Figures 1-3 A preferred embodiment of the present invention provides a purification structure comprising: a mounting base 1, a purification body 3, and a fan component 6; the mounting base 1 is connected to a magnet 11, which is used to attract the shell of a train; the mounting base 1 is connected to a support rod 2, which extends axially along the mounting base 1; the purification body 3 is provided with a gas inlet 31, a purification chamber 32, and a gas outlet 33 connected in sequence, and the purification body 3 also has an installation port 4 communicating with the purification chamber 32; the purification chamber 32 contains a filter element 5, which is detachably installed in the purification chamber 32; the mounting base 1 is detachably installed in the installation port 4, and the support rod 2 abuts against the filter element 5 to prevent the filter element 5 from falling out of the installation port 4; the fan component 6 is installed in the purification chamber 32.

[0034] During operation, the fan component 6 rotates, generating negative pressure to draw unpurified external air into the purification chamber 32 through multiple gas inlets 31. The air then passes through the filter element 5 within the purification chamber 32 for purification, removing particulate matter, dust, and harmful gases. The thoroughly purified air is then discharged in an orderly manner through the gas outlet 33, achieving continuous purification of the ambient air.

[0035] Since the mounting base 1 is connected to a magnet 11, which is used to attract the train's shell, the purification structure can be fixed by the attraction between the magnet 11 and the train shell. This allows the device to be quickly fixed and removed without tools, improving installation efficiency and applicability. The purification body 3 is provided with a gas inlet 31, a purification chamber 32, and a gas outlet 33 connected in sequence. The purification chamber 32 contains a filter element 5, and a fan component 6 is installed inside the purification chamber 32. Therefore, when the fan component 6 is working, it can attract unpurified air to enter through the gas inlet 31, be filtered and purified by the filter element 5, and finally be discharged from the gas outlet 33, achieving the effect of air purification. Since the filter element 5 is detachably installed inside the purification chamber 32, the mounting base 1 is detachably connected to the train shell, and the mounting base 3 is detachably installed at the mounting port 4, and the support rod 2 extends along the axial direction of the mounting base 1 and abuts against the filter element 5, the filter element 5 can be quickly disassembled and replaced, which also facilitates the maintenance of other internal components. At the same time, it ensures that the filter element 5 remains firmly in place during frequent vehicle operation, preventing accidental detachment due to vibration or airflow impact. Since the lamp 8 is installed on the purification body 3, and the gas outlet 33 faces the lamp 8, the purified air can be directly blown onto the lamp 8 through the gas outlet 33, effectively removing dust adhering to the surface of the lamp 8 and carrying away the heat generated by the lamp 8 during operation.

[0036] Preferably, in this embodiment, the purification body 3 is provided with a limiting part 7, which is disposed within the purification chamber 32. The limiting part 7 and the support rod 2 together clamp the filter element 5. The correct installation of the filter element 5 in the purification structure is crucial for the purification effect. If the filter element 5 shifts or becomes loose, some unpurified air may bypass the filter element 5, thereby reducing the overall purification efficiency and even causing internal contamination of the purification chamber 32. Long-term vibration may also cause wear on the filter element 5, affecting its service life. By setting the limiting part 7 and the support rod 2 in synergy, the filter element 5 can be effectively prevented from shifting or falling off due to vibration during vehicle operation, ensuring that the filter element 5 is always in the correct working position, thereby improving the stability and reliability of the purification structure, extending the service life of the filter element 5, and ensuring the continuity of the air purification effect.

[0037] Preferably, in this embodiment, the filter element 5 and the fan component 6 are arranged sequentially and at intervals along the airflow direction. By placing the filter element 5 upstream of the fan component 6, the fan component 6 draws in air that has undergone preliminary filtration, reducing wear of the fan blades by dust particles and extending the lifespan of the fan component 6; it also helps improve air purification efficiency and avoids the direct discharge of unfiltered air, which would affect air quality. The spacing between the filter element 5 and the fan component 6 is also designed to help form a more stable and uniform airflow path, avoiding purification blind spots caused by excessively strong or weak local airflow.

[0038] Preferably, in this embodiment, the purification body 3 includes a first branch body 34 and a second branch body 35, which are detachably connected. The fan component 6 is located in the first branch body 34, and the filter element 5 is located in the second branch body 35. When the filter element 5 reaches the end of its service life, only the second branch body 35 needs to be removed for filter element 5 replacement, without affecting the fan component 6 in the first branch body 34. If the fan component 6 malfunctions or needs upgrading, the first branch body 34 can also be disassembled separately for repair or replacement without discarding the entire device. This design not only improves the maintainability and expandability of the equipment but also significantly reduces usage and maintenance costs, enhancing the product's applicability in various application scenarios. By setting the fan component 6 and the filter element 5 in two independent branch bodies, the functions of the power system and the purification system are separated, making the overall structure clearer and more reasonable, and facilitating flexible adjustment of the selection of the fan component 6 and the filter element 5.

[0039] Preferably, in this embodiment, the first branch body 34 and the second branch body 35 are threaded together. Threaded connection is a common detachable connection design, technologically mature and widely used, providing a stable and reliable connection. This connection method is not only easy to operate but also has good sealing performance, preventing air leakage between the two branches and ensuring that unpurified air must pass through the filter element 5 before being delivered by the fan component 6, thus improving purification efficiency. Furthermore, threaded connection also has strong vibration resistance, reducing loosening problems caused by vibration, lowering the risk of wear between components, and helping to extend the overall service life of the equipment, making it suitable for environments with frequent vibrations, such as trains.

[0040] Preferably, in this embodiment, the mounting base 1 is threadedly connected to the second branch body 35. Thus, rotating the mounting base 1 drives the support column to compress the filter element 5, thereby sealing the mounting port 4. Simultaneously, during the rotational advancement process, the mounting base 1 effectively seals the mounting port 4 of the purification chamber 32, preventing unfiltered air from leaking from the mounting port 4. This structural design not only facilitates the rapid installation and removal of the filter element 5 but also enhances sealing and connection reliability, further improving the overall stability of the purification structure.

[0041] Preferably, in this embodiment, multiple gas inlets 31 are provided, and the multiple gas inlets 31 are distributed circumferentially around the purification body 3. Providing multiple gas inlets 31 on the outer periphery of the purification body 3, instead of a single air inlet, allows air to enter the purification chamber 32 from multiple directions, significantly increasing the air intake area, reducing local wind resistance, and improving air intake efficiency. These gas inlets 31 are equally spaced along the circumference of the purification body 3, ensuring a more uniform airflow in space, effectively dispersing airflow pressure, and making the equipment operate more quietly and smoothly.

[0042] The present invention also provides a vehicle-mounted lighting fixture, including a lamp 8 and the aforementioned purification structure; the lamp 8 is mounted on the purification body 3, the lamp 8 has a switch 81, and the gas outlet 33 faces the lamp 8. Purified air, driven by a fan component 6, is blown towards the lamp 8 through the gas outlet 33. This serves two purposes: firstly, it removes the heat generated by the lamp 8 during operation, thus aiding in heat dissipation; secondly, it removes dust adhering to the surface of the lamp 8, delaying its aging and improving lighting performance.

[0043] Preferably, in this embodiment, the lamp 8 extends circumferentially around the purification body 3, and multiple gas outlets 33 are provided, which are distributed at intervals around the purification body 3 and surrounded by the lamp 8. This arrangement allows purified air to be blown towards the lamp 8 from multiple directions, reducing dead corners and achieving better cleaning results without the need for frequent manual cleaning. The more uniform airflow distribution also helps to balance the temperature gradient of different parts of the lamp 8, preventing light source aging or material deformation due to localized overheating, thereby further extending the lifespan of the lamp 8 and improving lighting stability.

[0044] Preferably, in this embodiment, the lamp 8 is detachably connected to the purification body 3. This design allows users to remove the lamp 8 individually for cleaning, replacement, or repair as needed without affecting the normal operation of the purification structure. For example, when the lamp 8 is heavily dusty or the light source is damaged, it can be easily removed, replaced, or cleaned, and then reinstalled to restore normal use. This design greatly improves the maintainability and flexibility of the equipment, reduces subsequent maintenance costs, and also facilitates the replacement of different models of lamps 8 to meet diverse lighting needs.
