Detailed Description

In order that the above objects, features and advantages of embodiments according to the present application may be more clearly understood, embodiments according to the present application will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that features of embodiments according to the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments according to the present application, however, embodiments according to the present application may be practiced in other ways than those described herein, and therefore the scope of protection afforded by embodiments according to the present application is not limited by the specific embodiments disclosed below.

Some embodiments provided in accordance with the present application are described below with reference to fig. 1-4.

As shown in fig. 1, an embodiment according to a first aspect of the present application provides a pipe cover 10 for an exhaust pipe 200. The tube cover 10 includes a cover body 100 and a cover body 102. The cover body 100 is used for waterproofing. One end of cover 102 is connected to exhaust pipe 200, and the other end of cover 102 is provided with cover 100. An exhaust part 104 is formed on at least a part of the side wall of the cover 102, and an exhaust hole 106 is formed on the exhaust part 104.

In this embodiment, one end of the cover body 102 is connected to the exhaust pipe 200, the other end is provided with the cover body 100, and the side wall is provided with the exhaust hole 106, so that the gas in the exhaust pipe 200 is exhausted from the side of the cover body 102. By adopting the side exhaust mode and providing the cover body 100 at the other end of the cover body 102, although the airflow may impact the cover body 100, the airflow is dispersed through the exhaust holes 106 of the exhaust part 104, so that the airflow velocity can be reduced, the impact of the airflow on the cover body 100 can be reduced, and accordingly, the noise caused by the cover body 100 slapping the cover body 102 can be reduced. Further, the exhaust holes 106 are formed in the side wall of the cover body 102, and after the pipe cover 10 is mounted on the exhaust pipe 200 exhausting air toward the sky, the exhaust holes 106 are oriented in a substantially horizontal direction rather than a vertical direction, thereby reducing the phenomenon that rainwater enters the exhaust pipe 200. The cover body 100 may shield the exhaust pipe 200 from water in the vertical direction.

In the above embodiment, the exhaust portion 104 is located on one side of the cover 102, that is, the exhaust portion 104 is not provided on the entire circumferential direction of the cover 102, but the exhaust portion 104 is provided only on a part of the circumferential side wall. With this structure, the exhaust hole 106 can be directed to one side of the vehicle 30 when the pipe cover 10 is attached, so that the side vehicle 30 can be avoided, and the phenomenon that exhaust gas is blown straight to the side vehicle 30 or a person can be avoided. Of course, the exhaust hole 106 may also face the side vehicle, and particularly, when a plurality of exhaust holes 106 are provided, the air flow may be dispersed and decelerated, so that the influence on the side vehicle may be reduced.

In other embodiments, as shown in FIG. 4, vent 104 is provided in the circumferential direction of cover 102 over less than 180. Specifically, in the cross section of cover 102, a first line 120 is provided between the projection of one end of exhaust unit 104 and the projection of the center line of cover 102, a second line 122 is provided between the projection of the other end of exhaust unit 104 and the projection of the center line of cover 102, and an angle α between first line 120 and second line 122 is smaller than 180 °.

The structure that a first connecting line 120 is formed between the projection of one end of the exhaust part 104 on the cross section of the cover 102 and the projection of the center line of the cover 102 on the cross section of the cover 102, a second connecting line 122 is formed between the projection of the other end of the exhaust part 104 on the cross section of the cover 102 and the projection of the center line of the cover 102 on the cross section of the cover 102, and the included angle alpha between the first connecting line 120 and the second connecting line 122 is smaller than 180 degrees can be simply understood as that the connecting line between the two ends of the exhaust part 104 and the center line of the cover 102 is approximately fan-shaped, and the included angle alpha of the fan shape is smaller than 180 degrees. This structure also allows exhaust unit 104 to be provided only on one side of cover 102, which is advantageous for avoiding side vehicle 30 or a person. Further, the angle α is less than 180 °, preferably less than 160 °, for example 170 °, 160 °, 150 °, 130 °, 120 °, 100 °.

Further preferably, the angle α is 120 ° or more, 150 ° or less, for example, 150 °. The exhaust part 104 is disposed in the circumferential range of 120 ° to 150 ° of the cover 102, which is advantageous not only for avoiding the side vehicle 30 or the person, but also for avoiding the exhaust hole 106 from the front of the vehicle 30, thereby preventing the exhaust effect from being affected by the collision between the exhaust gas and the air in the front when the vehicle 30 travels. In addition, the included angle α is smaller than 180 °, which is beneficial to avoiding some parts of the vehicle 30 and avoiding the harmful effect of the exhaust gas on the parts. In addition, the included angle alpha is set within the range of 120-150 degrees, and more exhaust holes 106 can be arranged, thereby ensuring the exhaust efficiency.

The exhaust portion 104 is provided with a plurality of exhaust holes 106, which is beneficial to diffusing airflow and reducing gas pressure. After the gas pressure is reduced, the influence on the side vehicles and personnel is favorably reduced. In addition, the reduction of the gas pressure is beneficial to reducing the gas flow velocity, weakening the intensity of vibration noise and realizing the purpose of noise reduction.

In any of the above embodiments, the vent hole 106 is provided with a projection in the circumferential direction, and the projection projects outward of the cover 102. Therefore, rainwater flowing along the side wall of the cover body 102 can be prevented from entering the cover body 102 from the exhaust holes 106 by blocking part of rainwater flowing along the side wall through the protrusions, and the waterproof effect of the pipe cover 10 is improved.

It should be noted that the tube cover 10 is mainly used for air exhaust and water proofing, and is not used as a force-bearing structure, so that the thickness is generally thin. The vent hole 106 is mainly produced in a stamped form because of its thin thickness. Thus, a protrusion is naturally left around the vent hole 106 during the process. The remaining protrusions, when assembled, are directed outwardly of the cover 102 and naturally act as a water barrier and waterproof for the vent hole 106.

In any of the above embodiments, the cross-sectional area of the end of cover 102 connected to cover 100 is greater than the cross-sectional area of the end of cover 102 connected to exhaust pipe 200. Specifically, cover 102 has a shape with a large top and a small bottom. Therefore, partial rainwater can be blocked by the side wall of the cover body 102 through the larger top part which is the lower smaller bottom part, and the waterproof effect of the cover body 102 is improved. It is understood that the exhaust portion 104 is provided at a position where the cross-sectional area is small. For example, the housing 102 may be stepped, with the top having a large step and the bottom having a small step, and the exhaust section 104 may be located on the smaller step.

In other embodiments, the same is a roof-sized structure, however, the cross-sectional area of the shroud 102 is gradually changing. Specifically, the cross-sectional area of the housing 102 gradually increases in a direction from the end of the housing 102 connected to the exhaust pipe 200 to the cover 100, that is, the housing 102 has a substantially funnel shape, or a shower shape. This may also improve the waterproofing of enclosure 102. Further, the gradual change structure also makes the side wall of the cover body 102 be an inclined shape, and under the action of gravity, the difficulty that water on the side wall continuously flows along the side wall is increased, so that the water flow on the side wall is reduced, the water quantity flowing into the exhaust hole 106 along the side wall can be correspondingly reduced, and the waterproof performance of the cover body 102 is further improved. It should be noted that under the action of gravity and the blocking action of the top portion above, rainwater is hard to contact the side walls arranged obliquely, and the waterproof performance of the cover 102 is further improved. In addition, the obliquely arranged side wall also facilitates the exhaust direction of at least part of the exhaust holes 106 to be obliquely downward after being mounted on the exhaust pipe 200, thereby further reducing the phenomenon of direct blow to the side vehicle 30 or the person.

In any of the above embodiments, the duct cover 10 further includes a priming cover rim 108. The priming shroud rim 108 is attached to the cover body 100. The priming cover edge 108 extends out of the cover body 102 and extends towards the bottom of the cover body 102.

In this embodiment, by providing the water guiding cover rim 108, and extending the water guiding cover rim 108 out of the cover body 102, the cover body 102 can block rainwater, which has an effect similar to an umbrella, thereby further improving the waterproof performance of the pipe cover 10. Further, the water guiding cover edge 108 extends towards the bottom of the cover body 102, and after the pipe cover 10 is mounted on the exhaust pipe 200, the water guiding cover edge 108 extends downward approximately, so that water flowing down from the cover body 100 is guided to directly drop under the action of gravity, the water is prevented from flowing into the exhaust hole 106 along the side wall of the cover body 102, and the waterproof effect of the pipe cover 10 is further improved.

In some embodiments, the priming shroud rim 108 is integrally formed with the cover body 100. In other embodiments, the priming shroud rim 108 and the cover body 100 are welded together.

In any of the above embodiments, the cross-sectional area of the cover 100 gradually decreases in the bottom-to-top direction. As shown in fig. 1, for example, the cover body 100 has a spherical shape. Or the cover body 100 is in a pyramid shape or an inverted funnel shape.

The spherical cover 100, the pyramidal cover 100, or the inverted funnel cover 100 has a slope. Such a structure facilitates guiding water to flow downward from the top of the cover body 100, which is advantageous to prevent water from accumulating on the cover body 100.

In other embodiments, the cover 100 is plate-shaped, i.e., a flat plate. Flat plate-shaped cover 100 is connected to cover 102 in an inclined manner. After the pipe cover 10 is attached to the exhaust pipe 200, the cover body 100 is inclined with respect to the horizontal plane to guide the flow of water, so that the formation of water accumulation on the cover body 100 can be prevented even if the cover body 100 itself is flat.

In any of the above embodiments, the tube cover 10 further comprises a connection tube 110. The connecting tube 110 is connected to an end of the cover 102 away from the cover 100. The connection pipe 110 is used to connect the housing 102 and the exhaust pipe 200.

In this embodiment, by providing the connection pipe 110, convenience of connection between the poppet cover 10 and the exhaust pipe 200 is facilitated.

In the above embodiment, the end of the connection pipe 110 away from the cover 102 is provided with a fitting groove 112. Specifically, one end of connection pipe 110 for connection with exhaust pipe 200 is provided with fitting groove 112. Due to the arrangement of the assembling groove 112, the end of the connecting pipe 110 with the assembling groove 112 can be properly enlarged, so that the connecting pipe 110 is sleeved on the exhaust pipe 200, and the convenience of assembling and aligning is improved. In addition, the size of connecting pipe 110 can be made very close to that of exhaust pipe 200, so that the gap between connecting pipe 110 and exhaust pipe 200 is reduced, and the stability and reliability of the connection between the two are improved.

Further, the tube housing 10 further includes a connector. A connector is provided on the connection pipe 110, and the connector is used to fix the connection pipe 110 and the exhaust pipe 200.

In this embodiment, an assembling groove 112 is formed at an end of the connecting pipe 110 away from the cover body 102, and the connecting pipe 110 and the exhaust pipe 200 are fixed by a connecting member, so that the connecting pipe 110 is fixed, and the pipe cover 10 is prevented from falling off from the exhaust pipe 200, thereby improving the stability and reliability of the operation of the pipe cover 10.

In some embodiments, the connection is a pipe clamp 114. The exhaust pipe 200 and the connection pipe 110 are fixed by the pipe clamp 114, so that the use is convenient, the structure is simple, and the maintenance is easy. Of course, the connecting member may be a flange, a latch, or the like.

In some embodiments, cover 100 is secured to cover 102. This is advantageous in preventing the cover 100 from slapping the cover 102 when impacted, and accordingly, noise generated when the cover 100 slaps the cover 102 is prevented.
