Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle ventilation valves, and in particular to a ventilation valve and a vehicle having the same. Background Art

[0002] In the prior art, the air pressure in the sealed cavity on a vehicle often changes with changes in various factors such as temperature. Therefore, a breathable valve is often provided on the shell of the sealed cavity on the vehicle to ensure the pressure balance between the sealed cavity and the outside world to ensure the safe driving of the vehicle.

[0003] During the use of a vehicle, there will be a large amount of water vapor in the air, and the vehicle itself may also wade through water. In order to prevent water from entering the sealed cavity through the breathable valve and causing damage to various structures in the sealed cavity, a polymer waterproof and breathable membrane is often set on the breathable valve to block the water.

[0004] However, there is often lubricating oil in the sealed cavity, and the polymer waterproof breathable membrane on the existing breathable valve has an adsorption effect on oil molecules. When the gas in the sealed cavity is discharged through the breathable valve, the gas will carry lubricating oil molecules, and the lubricating molecules will be adsorbed by the polymer waterproof breathable membrane. In addition, during the driving process of the vehicle, there is also a situation where some lubricating oil in the sealed cavity is splashed onto the polymer waterproof breathable membrane and adsorbed by it. Over time, the air permeability of the polymer waterproof breathable membrane will decrease or even become blocked. Utility Model Content

[0005] The embodiments of the present disclosure provide a vent valve and a vehicle having the same, which can solve the above-mentioned technical problems existing in the related art. The technical solution is as follows:

[0006] In a first aspect, a breathable valve is provided, comprising a valve body and a waterproof breathable membrane;

[0007] The valve body includes a shell and an intercepting structure. The shell is open at both ends and has a gas passage inside. The intercepting structure is located in the gas passage. The intercepting structure includes a connecting block, a first intercepting block, and a second intercepting block. The first intercepting block and the second intercepting block are both connected to the connecting block and to the inner wall of the shell. The projections of the first intercepting block and the second intercepting block on a plane perpendicular to the extension direction of the gas passage do not overlap or have a gap. There is a gap between the first intercepting block and the second intercepting block in the extension direction of the gas passage to form a connecting seam.

[0008] The waterproof and breathable membrane covers the opening at one end of the shell.

[0009] In a possible implementation manner, projections of the first intercepting block and the second intercepting block on a plane perpendicular to the extension direction of the gas channel are symmetrical to each other.

[0010] In a possible implementation manner, the first intercepting block is not perpendicular to the extending direction of the gas channel, and the second intercepting block is perpendicular to the extending direction of the gas channel.

[0011] In a possible implementation manner, the second intercepting block is not perpendicular to the extension direction of the gas channel, and the first intercepting block is perpendicular to the extension direction of the gas channel.

[0012] In a possible embodiment, the distance from each position on the surface of the first interception block away from the waterproof breathable membrane to the waterproof breathable membrane is negatively correlated with the distance from each position on the surface of the first interception block away from the waterproof breathable membrane to the second interception block, and the distance from each position on the surface of the second interception block away from the waterproof breathable membrane to the waterproof breathable membrane is negatively correlated with the distance from each position on the surface of the second interception block away from the waterproof breathable membrane to the first interception block.

[0013] In a possible implementation, the shell and the intercepting structure are integrally formed.

[0014] In a possible embodiment, the breathable valve further includes a filtering structure, which is located in the gas channel, between the intercepting structure and the waterproof breathable membrane, spaced apart from the waterproof breathable membrane, and connected to the inner wall of the housing.

[0015] In a possible embodiment, the outer shell has a first shell segment and a second shell segment connected to each other, the outer edge of the first shell segment has a connecting portion for connecting to a cavity to be ventilated, and the intercepting structure is located in the first shell segment.

[0016] In one possible embodiment, the outer shell includes a second shell segment and a third shell segment connected to each other, the third shell segment is used to be connected to the waterproof breathable membrane, and the breathable valve also includes an end cover, which is used to be connected to the third shell segment. When the end cover is connected to the third shell segment, a flow channel is formed between the end cover and the third shell segment to connect the gas channel with the outside world.

[0017] In one possible embodiment, the inner wall of the end cover has a plurality of bosses, which are used to abut against the end of the third shell segment. The plurality of bosses are spaced apart from each other to form a plurality of first notches. The third shell segment has a plurality of second notches, which are used to communicate with the plurality of first notches in a one-to-one correspondence to form a plurality of the flow channels.

[0018] In a possible implementation, the third shell segment has a positioning protrusion, and the inner wall of the end cover has a positioning groove, and the positioning groove is used to cooperate with the positioning protrusion in a limiting manner.

[0019] In a second aspect, a vehicle is provided, comprising the ventilation valve according to any one of the first aspects.

[0020] The beneficial effects of the technical solution provided by the present disclosure include at least:

[0021] When the vent valve is connected to the cavity to be ventilated, the first and second intercepting blocks can block the oil in the cavity, thereby preventing the oil from splashing onto the waterproof breathable membrane. Furthermore, during the process of pressure balancing between the cavity and the outside world, the gas flowing out of the cavity will carry the oil with it, and the two will form a gas-liquid mixture. When the gas-liquid mixture passes through the first and second intercepting blocks, due to the relatively small inertia of the gas and the relatively large inertia of the oil, the gas portion of the gas-liquid mixture will bypass the first and second intercepting blocks and flow out of the connecting seam to the outside world, while the liquid portion will collide with the first and second intercepting blocks and gradually accumulate on the first and second intercepting blocks, eventually falling back into the cavity to be ventilated, thereby preventing the oil in the gas-liquid mixture from reaching the location of the waterproof breathable membrane. As a result, the vent valve can effectively prevent the oil in the cavity to be ventilated from contacting and being adsorbed by the waterproof breathable membrane, thereby alleviating the problem of reduced air permeability of the waterproof breathable membrane and increasing the service life of the waterproof breathable membrane.

[0035] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] The embodiment of the present disclosure provides a breathable valve, such as Figure 1 、 Figure 2 and Figure 3 As shown, the breathable valve includes a valve body 1 and a waterproof breathable membrane 2. The valve body 1 includes an outer shell 11 and an interception structure 12. The outer shell 11 is open at both ends and has a gas channel inside. The interception structure 12 is located in the gas channel. The interception structure 12 has a connecting block 121, a first interception block 122, and a second interception block 123. The first interception block 122 and the second interception block 123 are both connected to the connecting block 121 and to the inner wall of the outer shell 11. The projections of the first interception block 122 and the second interception block 123 on a plane perpendicular to the extension direction of the gas channel do not overlap or have a gap, and there is a gap in the extension direction of the gas channel to form a connecting seam. The waterproof breathable membrane 2 covers the opening at one end of the outer shell 11.

[0038] When the breathable valve provided in the embodiment of the present disclosure is connected to the cavity to be ventilated, the first interception block 122 and the second interception block 123 can block the oil in the cavity, thereby preventing the oil in the cavity from splashing onto the waterproof breathable membrane 2.

[0039] Moreover, in the process of pressure balance between the cavity and the outside world, the gas flowing out of the cavity will carry oil and form a gas-liquid mixture. When the gas-liquid mixture passes through the first interception block 122 and the second interception block 123, due to the relatively small inertia of the gas and the relatively large inertia of the oil, the gas part of the gas-liquid mixture will bypass the first interception block 122 and the second interception block 123 and flow to the outside world from the connecting seam, while the liquid part will collide with the first interception block 122 and the second interception block 123 and gradually accumulate on the first interception block 122 and the second interception block 123, and finally fall back into the cavity to be ventilated, thereby preventing the oil in the gas-liquid mixture from reaching the position where the waterproof breathable membrane 2 is located.

[0040] Therefore, the breathable valve effectively alleviates the situation where the oil in the cavity to be ventilated contacts and is adsorbed by the waterproof breathable membrane 2, thereby alleviating the problem of reduced air permeability of the waterproof breathable membrane 2 and increasing the service life of the waterproof breathable membrane 2.

[0041] Among them, "the first interception block 122 and the second interception block 123 are both connected to the inner wall of the outer shell 11", "the projections of the first interception block 122 and the second interception block 123 on the plane perpendicular to the extension direction of the gas channel do not overlap and there is no gap", which means that after the projections of the first interception block 122 and the second interception block 123 on the plane perpendicular to the extension direction of the gas channel are combined, they coincide with the projection of the part of the interception structure 12 in the gas channel on the plane perpendicular to the extension direction of the gas channel.

[0042] Optionally, the waterproof breathable membrane 2 may be an ePTFE (expanded Polytetrafluoroethylene) membrane.

[0043] In one implementation of the embodiment of the present disclosure, Figure 2 As shown, the projections of the first intercepting block 122 and the second intercepting block 123 on a plane perpendicular to the extension direction of the gas channel are symmetrical to each other.

[0044] In this way, it can be ensured that the first interception block 122 and the second interception block 123 have a suitable contact area with the gas-liquid mixture, avoiding the situation where one of the first interception block 122 and the second interception block 123 has a smaller contact area with the gas-liquid mixture, thereby ensuring the separation effect of the first interception block 122 and the second interception block 123 on gas and oil.

[0045] Optionally, the gas channel can be cylindrical, and the first intercepting block 122 and the second intercepting block 123 can be two symmetrical semicircular bodies, and after the projections of the two semicircular bodies on the plane perpendicular to the extension direction of the gas channel are spliced ​​together, they overlap with the projection of the gas channel on the plane perpendicular to the extension direction of the gas channel.

[0046] Optionally, the connecting block 121 may be a small cylinder for connecting two intercepting blocks.

[0047] In one implementation of the embodiment of the present disclosure, the first intercepting block 122 is not perpendicular to the extension direction of the gas channel, and the second intercepting block 123 is perpendicular to the extension direction of the gas channel.

[0048] In this way, the contact area between the first interception block 122 and the gas-liquid mixture can be increased, thereby improving the separation effect of the first interception block 122 on gas and oil; and, part of the first interception block 122 will be tilted close to one side inside the cavity, thereby being able to guide the oil accumulated on the first interception block 122 so that it can quickly fall back into the cavity.

[0049] In one implementation of the embodiment of the present disclosure, the second intercepting block 123 is not perpendicular to the extension direction of the gas channel, and the first intercepting block 122 is perpendicular to the extension direction of the gas channel.

[0050] In this way, the contact area between the second interception block 123 and the gas-liquid mixture can be increased, thereby improving the separation effect of the second interception block 123 on gas and oil; and, part of the second interception block 123 will be tilted close to one side inside the cavity, thereby being able to guide the oil accumulated on the second interception block 123 so that it can quickly fall back into the cavity.

[0051] In one implementation of the embodiment of the present disclosure, the distance from each position on the surface of the first interception block 122 away from the waterproof breathable membrane 2 to the waterproof breathable membrane 2 is negatively correlated with the distance from each position on the surface of the first interception block 122 away from the waterproof breathable membrane 2 to the second interception block 123, and the distance from each position on the surface of the second interception block 123 away from the waterproof breathable membrane 2 to the waterproof breathable membrane 2 is negatively correlated with the distance from each position on the surface of the second interception block 123 away from the waterproof breathable membrane 2 to the first interception block 122.

[0052] Optionally, when the first intercepting block 122 is tilted, the angle between the first intercepting block 122 and the extension direction of the gas channel is 80°-85°.

[0053] Optionally, when the second intercepting block 123 is tilted, the angle between the second intercepting block 123 and the extension direction of the gas channel is 80°-85°.

[0054] In one implementation of the embodiment of the present disclosure, the housing 11 and the intercepting structure 12 are integrally formed.

[0055] In this way, the structural strength of the interception structure 12 can be improved, and the interception structure 12 can be prevented from loosening during use. In addition, the production process of the breathable valve can be simplified, and the production efficiency of the breathable valve can be greatly improved.

[0056] In one embodiment, the breathable valve is injection molded.

[0057] In the breathable valve provided by the embodiment of the present disclosure, the projections of the first intercepting block 122 and the second intercepting block 123 on a plane perpendicular to the extension direction of the gas channel do not overlap, which can ensure that the injection molding process can be carried out and demolding can be achieved more conveniently.

[0058] In one implementation of the embodiment of the present disclosure, Figure 1 、 Figure 4 and Figure 5 As shown, the breathable valve further includes a filter structure 3 , which is located in the gas channel and between the interception structure 12 and the waterproof breathable membrane 2 , and is spaced apart from the waterproof breathable membrane 2 and connected to the inner wall of the housing 11 .

[0059] in, Figure 5 yes Figure 4 Cross-sectional view of the vent valve on plane AA.

[0060] With the breathable valve provided in the embodiment of the present disclosure, the oil in the cavity to be ventilated is intercepted by the interception structure 12 after being splashed or entering the breathable valve with the gas. At this time, most of the oil will fall back into the cavity under the action of the interception structure 12, while some of the oil that escapes the interception of the interception structure 12 may continue to move upward under the action of inertia or pressure. By setting up the filtering structure 3, this part of the oil can be filtered to prevent it from being adsorbed by the waterproof breathable membrane 2, thereby further preventing the oil from contacting the waterproof breathable membrane 2, thereby improving the service life of the waterproof breathable membrane 2.

[0061] Optionally, the filter structure 3 may be a non-woven fabric.

[0062] Optionally, the filter structure 3 is interference-connected to the inner wall of the housing 11 .

[0063] In one implementation of the embodiment of the present disclosure, Figure 1 As shown, the outer shell 11 has a first shell segment 111 and a second shell segment 112 connected to each other. The outer edge of the first shell segment 111 has a connecting portion 1111 for connecting to a cavity to be ventilated. The intercepting structure 12 is located in the first shell segment 111.

[0064] Optionally, the connection portion 1111 may be an external thread.

[0065] Optionally, the breathable valve further includes a sealing ring 5, which is located on the side of the connecting portion 1111 to seal the connecting position between the connecting portion 1111 and the cavity to be sealed.

[0066] In one embodiment, if Figure 1 As shown, the first shell section 111 also has a gripping portion 1112, which is spaced apart from the connecting portion 1111, and the interface thereof is polygonal, so that the worker's hand or installation tool can easily grip the vent valve to connect it to the cavity to be ventilated.

[0067] In one implementation of the embodiment of the present disclosure, Figure 1 As shown, the outer shell 11 includes a second shell segment 112 and a third shell segment 113 connected to each other. The third shell segment 113 is used to be connected to the waterproof breathable membrane 2. The breathable valve also includes an end cover 4, which is used to be connected to the third shell segment 113. When the end cover 4 is connected to the third shell segment 113, a flow channel is formed between the end cover 4 and the third shell segment 113 to connect the gas channel with the outside world.

[0068] In this way, the waterproof breathable membrane 2 can be protected by the end cap 4 to prevent the waterproof breathable membrane 2 from being damaged due to environmental factors, thereby extending the service life of the waterproof breathable membrane 2.

[0069] Optionally, the second shell segment 112 is arranged to protrude from the first shell segment 111 .

[0070] In one implementation of the embodiment of the present disclosure, Figure 1 As shown, the inner wall of the end cover 4 has a plurality of bosses 41, which are used to abut against the end of the third shell segment 113. The plurality of bosses 41 are spaced apart from each other to form a plurality of first notches 42. The third shell segment 113 has a plurality of second notches 1131, which are used to communicate with the plurality of first notches 42 in a one-to-one correspondence to form a plurality of flow channels.

[0071] In this way, when the end cap 4 is installed, the boss 41 contacts the end cap 4 to limit the installation position of the end cap 4, so as to ensure that a gap is formed between the end of the end cap 4 and the waterproof breathable membrane 2, thereby ensuring the flow efficiency of gas.

[0072] In addition, in the related art, the breathable valve is used in water, and water will flow between the end cap and the waterproof breathable membrane. If the flow channel at the end cap of the breathable valve is inclined upward, water will accumulate between the end cap and the waterproof breathable membrane, and the accumulated water cannot be discharged in time, thereby seriously reducing the ventilation effect of the breathable valve.

[0073] The vent valve provided in this embodiment, by providing multiple flow channels, can ensure that accumulated water in the vent valve can be promptly drained during use in water, thereby ensuring the venting effect of the vent valve. Furthermore, during normal use of the vent valve, the multiple flow channels can increase the flow rate of gas, thereby also improving the venting effect of the vent valve.

[0074] In one embodiment, four flow channels are formed between the end cover 4 and the third shell segment 113 , and the four flow channels are evenly distributed along the edge of the third shell segment 113 .

[0075] In one implementation of the embodiment of the present disclosure, Figure 1 As shown, the third shell segment 113 has a positioning protrusion 1132 , and the inner wall of the end cover 4 has a positioning groove, which is used to limit and cooperate with the positioning protrusion 1132 .

[0076] Thus, when the end cap 4 is snapped onto the second shell segment 112, the positioning protrusion 1132 and the positioning groove cooperate with each other, thereby preventing the end cap 4 from falling off. Furthermore, when connecting the end cap 4 to the second shell segment 112, the positioning protrusion 1132 and the positioning groove are melted by heating the end cap 4 on one side of the positioning groove. After the heating is stopped, the melted portion cools, thereby completing the connection between the end cap 4 and the second shell segment 112. Thus, the cooperation between the positioning protrusion 1132 and the positioning groove can greatly improve the convenience of connecting the end cap 4 to the valve body 1.

[0077] An embodiment of the present disclosure further provides a vehicle, which includes the above-mentioned ventilation valve.
