Description

Technical Field

[0001] This utility model belongs to the field of air duct technology, specifically an exhaust device and a vehicle. Background Technology

[0002] In enclosed or semi-enclosed spaces such as rail vehicles and passenger cars, air supply systems are typically installed to ensure indoor air quality and passenger comfort. These systems continuously deliver fresh air into the room, causing the indoor air pressure to be slightly higher than the outdoor ambient pressure (i.e., creating positive pressure). To maintain pressure balance and expel stale air and excess gas from the room to the outside, a dedicated exhaust system (also called a waste exhaust system) is required.

[0003] Among related technologies, some use natural ventilation devices for passive exhaust; however, in rainy, snowy, or dusty weather, foreign objects such as rain, snow, and dust can easily backflow, affecting the indoor environment and leading to a poor experience. Others use powered ventilation devices (such as exhaust fans), which need to take into account functions such as protection against rain, snow, and dust, making their structure relatively complex, costly, and causing energy consumption and noise problems.

The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Firstly, please refer to Figures 1-3 As shown, this utility model embodiment provides an exhaust device, including: The ventilation component 100 has a ventilation channel 101 connecting the upper end and the lower end.

[0026] A housing assembly 200 covers the vent 100 and encloses at least a portion of the periphery of the vent 100. The periphery of the housing assembly 200 has at least one vent portion 201 communicating with the vent 101, the vent portion 201 being lower than the upper edge of the vent 100.

[0027] The lower end of at least one of the venting component 100 and the housing assembly 200 is used to connect with the component to be installed and to connect the venting duct 101 with the interior of the component to be installed so that the air inside the interior can be exhausted to the outside.

[0028] In this embodiment, the ventilation component 100 can be a square, round, or irregularly shaped pipe, and can be assembled or integrally formed. It is vertically arranged and has a ventilation channel 101 inside. Both the upper and lower ends of the ventilation component 100 are open. The ventilation component 100 can be connected to the top of the component to be installed (such as a locomotive, automobile, etc.). The lower opening can communicate with the interior of the component to be installed, such as with the driver's cab or various passenger compartments, so as to exhaust stale air.

[0029] In this embodiment, the housing assembly 200 is used to prevent foreign objects from the outside from flowing back into the room. It covers the vent 100 and encloses at least part of the periphery of the vent 100, meaning that the housing assembly 200 must at least cover the upper half of the vent 100. The housing assembly 200 can be connected to the top of the component to be installed or to the outer wall of the vent 100. One or more ventilation sections 201 (such as ventilation holes, ventilation slots, etc.) can be formed on the periphery of the housing assembly 200, and the ventilation sections 201 communicate with the ventilation channel 101.

[0030] The vent 201 is positioned below the upper edge of the vent 100. In particular, the distance between the vent 201 and the upper edge of the vent 100 is preferably greater than or equal to 10 cm, thereby effectively preventing the backflow of foreign objects from the outside.

[0031] In this way, the air in the chamber where the component is to be installed moves along the positive pressure. Figure 2 The air is discharged to the outside through the ventilation duct 101 and the ventilation section 201 in the direction indicated by the hollow arrow. When the installed part is moved, the headwind causes foreign objects from the outside to enter through the ventilation section 201. Since the upper edge of the ventilation part 100 is higher than the ventilation section 201, it can block most of the foreign objects from entering the room through the ventilation duct 101, thereby ensuring the indoor air quality and improving the experience.

[0032] In some embodiments, the vent 100 includes a first straight cylindrical section 110 and a first variable-diameter cylindrical section 120, the lower end of at least one of the first straight cylindrical section 110 and the housing assembly 200 being used to connect to the component to be installed.

[0033] The lower end of the first variable diameter cylindrical section 120 is connected to the upper end of the first straight cylindrical section 110 to form an internal ventilation channel 101. The outer diameter of the first variable diameter cylindrical section 120 increases from bottom to top.

[0034] Specifically, such as Figure 2 , Figure 3As shown, the first straight cylindrical section 110 can be a cylinder or a square tube, etc., and its outer perimeter remains unchanged from bottom to top. The lower end of the first straight cylindrical section 110 can be connected and fixed to the part to be installed. The lower end of the first variable diameter cylindrical section 120 can be connected to the upper end of the first straight cylindrical section 110 by welding or integral molding, and the outer diameter of the first variable diameter cylindrical section 120 increases from bottom to top.

[0035] In this way, when the foreign object moves from bottom to top, under the action of the outer wall of the first variable diameter cylinder section 120, at least part of the foreign object changes its upward direction to facilitate falling, and at the same time increases the resistance to the upward movement of the foreign object, thereby ensuring the lifting and blocking effect.

[0036] Furthermore, in this embodiment, the venting component 100 also includes a second variable diameter cylindrical section 130, the upper end of which is connected to the upper end of the first variable diameter cylindrical section 120, and the outer diameter of the second variable diameter cylindrical section 130 is arranged to increase from top to bottom.

[0037] That is, such as Figure 2 , Figure 3 As shown, the second variable-diameter cylindrical section 130 is connected to the first variable-diameter cylindrical section 120 to form an outward-flared flange structure. In this way, on the one hand, the upward direction of the foreign object can be further changed, and on the other hand, the blocking effect on the upward movement of the foreign object can be further improved.

[0038] Furthermore, in this embodiment, the lower edge of the second variable-diameter cylindrical section 130 projects onto the ventilation section 201 in the horizontal plane. In this way, if a foreign object moves upward in a straight line, most of the foreign object will be blocked by the flange structure formed by the second variable-diameter cylindrical section 130 and the first variable-diameter cylindrical section 120 and returned.

[0039] And / or, the outer wall of the first variable diameter section 120 and the outer wall of the second variable diameter section 130 are connected by an arc. In this way, when the foreign object moves upward along the outer walls of the first variable diameter section 120 and the second variable diameter section 130, the arc transition smoothly changes the direction of movement from upward to downward and returns.

[0040] In some embodiments, the housing assembly 200 includes a lower housing 210 and an upper housing 220, the lower housing 210 being sleeved on at least a portion of the outer side of the first cylindrical section 110, and the lower end of at least one of the lower housing 210 and the first cylindrical section 110 being used for connection with the component to be installed.

[0041] The upper housing 220 is mounted on the first variable diameter cylindrical section 120, and the lower side of the upper housing 220 is detachably connected to the upper side of the lower housing 210.

[0042] This design divides the housing assembly 200 into two parts: a lower housing 210 and an upper housing 220. This facilitates the processing of individual parts and subsequent installation, resulting in a more rational assembly and disassembly structure. The lower housing 210 and the upper housing 220 can be connected by screws, snap-fits, or plug-ins to meet the requirements for detachability.

[0043] Furthermore, in this embodiment, the lower housing 210 includes a second straight cylindrical section 211, an annular section 212, and a third straight cylindrical section 213. The lower end of at least one of the second straight cylindrical section 211 and the first variable diameter cylindrical section 120 is used to connect with the component to be installed.

[0044] The upper end of the second straight section 211 is connected to the inner ring surface of the annular section 212, the outer ring surface of the annular section 212 is connected to the lower end of the third straight section 213, the vent 201 is located on the annular section 212, and the upper side of the third straight section 213 is connected to the lower side of the upper shell 220.

[0045] Specifically, such as Figure 2 As shown, both the second straight section 211 and the third straight section 213 can be cylindrical or square, etc., with their outer dimensions remaining unchanged from bottom to top, but the outer dimension of the third straight section 213 is larger than that of the second straight section 211. Furthermore, the upper end of the second straight section 211 and the lower end of the third straight section 213 are connected by an annular section 212. Ventilation sections 201 are located on the annular section 212 and are evenly distributed and spaced apart along the axis of the annular section 212.

[0046] In addition, the second straight section 211 can be connected and fixed to the part to be installed, and the upper end of the third straight section 213 can be connected to the lower end of the upper housing 220 by means of screwing, snap-fitting, plugging, etc.

[0047] In some embodiments, the housing assembly 200 further includes a seal 230, with the upper side of the third straight section 213 inserted into the lower side of the upper housing 220, and the seal 230 filling the gap between the outer wall of the third straight section 213 and the inner wall of the upper housing 220.

[0048] Specifically, such as Figure 2 As shown, the seal 230 can be an EPDM rubber sealing ring or a sealing strip, which fills the gap between the outer wall of the third straight section 213 and the inner wall of the upper housing 220.

[0049] Furthermore, in this embodiment, the housing assembly 200 also includes at least one connector 240, which is connected to the third straight section 213 through at least the upper housing 220 and the seal 230.

[0050] Specifically, such as Figure 2As shown, the connector 240 can be a bolt, screw, etc. Through holes can be opened at corresponding positions on the upper housing 220 and the seal 230. Threaded holes or rivet nuts can be opened on the outer wall of the third straight section 213. After the bolt or screw passes through the through hole, it can be threadedly connected to the threaded hole or rivet nut for easy disassembly and assembly. In addition, multiple connectors 240 can be evenly distributed and spaced apart along the periphery of the third straight section 213 to ensure the stability of the connection.

[0051] Furthermore, in this embodiment, the exhaust device provided by this utility model further includes: The lower end of at least one of flange 300, vent 100 and housing assembly 200 is connected to flange 300, which is used to connect to the part to be installed.

[0052] For example, such as Figure 2 As shown, the housing assembly 200 is sleeved on the outside of the vent 100. The lower ends of the vent 100 and the housing assembly 200 are flush and can be connected to the upper end face of the flange 300 by welding, screwing, snapping, bonding, etc. Then the lower end face of the flange 300 can abut against the top surface of the part to be installed and be connected and fixed by welding, screwing, snapping, bonding, etc.

[0053] This facilitates installation and connection, while also ensuring installation stability. The specific dimensions and installation location of the flange 300 can be determined according to actual needs; this embodiment does not impose excessive restrictions.

[0054] Secondly, this utility model embodiment also provides a vehicle, including a vehicle body and an exhaust device provided in any of the above embodiments, wherein the lower end of at least one of the ventilation component 100 and the housing assembly 200 is connected to the top of the vehicle body, and the ventilation duct 101 communicates with the interior of the vehicle body.

[0055] The vehicle can be a locomotive, automobile, special vehicle, etc. The lower end of at least one of the ventilation component 100 and the housing assembly 200 can be installed on the top of the vehicle body by means of screwing, snapping, welding, etc., and the ventilation duct 101 is connected to the interior of the vehicle body, thereby enabling the natural exhaust of stale air from the interior.

[0056] Therefore, the vehicle provided in this embodiment of the present invention, by configuring an exhaust device, can prevent most of the foreign objects from entering the room through the ventilation duct 101 when they enter from the ventilation section 201, since the upper edge of the ventilation member 100 is higher than the ventilation section 201, thereby ensuring the indoor air quality and improving the experience.

[0057] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
