Description

Technical Field

[0001] The utility model relates to the technical field of mechanical power ventilation, and particularly relates to a vertical air valve for prolonging the water penetration time. Background Art

[0002] In motor vehicles, such as cars, SUVs and other automobiles or new energy vehicles, when closing the door, air will be compressed inside the vehicle, forming high pressure, which will not only make the people sitting in the car uncomfortable, but sometimes also compress automotive equipment, such as glass, etc. Therefore, a ventilation device is provided on components such as the car door or the vehicle frame of the automobile to ventilate when closing the door to balance the air pressure inside and outside the vehicle. In addition, the ventilation device is also used to exhaust the waste gas inside the motor vehicle. Therefore, a basic requirement for the ventilation device is that the air flow can only flow out of the vehicle through the ventilation device, and cannot flow into the vehicle from outside the vehicle.

[0003] For example, a double-layer ventilation device with a filtering function disclosed in the Chinese utility model CN202223602972.7 authorized by the applicant includes a housing, a ventilation structure, and a filtering device. The housing includes a first housing and a second housing. A water accumulation tank and a water guide tank are further arranged on the second housing. The valve plate structure includes a first valve plate and a second valve plate. The second valve plate covers the first valve plate. The filtering device includes a fixed pressing plate and a filter net. By arranging the filter net, it can effectively prevent dust, mosquitoes, etc. from entering the vehicle through the ventilation opening. And by arranging the valve plate structure, that is, making use of the sound insulation ability of non-woven fabric, and at the same time having the sealing property and elastic contraction function of silica gel, so as to ensure that the ventilation opening can isolate noise to the greatest extent while maintaining the function of one-way ventilation. Finally, by arranging the water accumulation tank and the water guide tank, it can effectively collect and guide the water vapor generated on both sides inside and outside the installation opening, preventing water flow from entering the vehicle.

[0004] Although by arranging a double-layer valve plate, it can play a role in reducing the flapping sound generated when the valve plate falls to a certain extent and achieve a noise reduction effect, but using a covering type valve plate will cause the valve plate to float under the action of buoyancy when the vehicle wades through water or the vehicle body gets water, and it cannot completely cover the ventilation opening, thus forming a gap, and further causing water to enter the vehicle interior. Summary of the Utility Model

[0005] In view of this, the utility model provides a vertical air valve for prolonging the water penetration time to solve the above technical problems.

[0006] A vertical air valve for extending the water penetration time, which comprises an installation housing, a plurality of valve plates arranged on the installation housing, and a sound insulation cover arranged on the installation housing. The housing comprises an installation opening, a plurality of ventilation openings arranged on the installation opening, a plurality of frames forming the ventilation openings, and a plurality of valve plate fixing members arranged on the frames. A receiving groove is arranged on the frame. The receiving groove is a sunken groove located on the contact surface between the frame and the valve plate, and the groove body size is larger than the size of the valve plate. One side of the receiving groove communicates with the ventilation opening, and the other side forms a blocking step. The thickness of the blocking step is greater than the thickness of the valve plate. The sound insulation cover is a cover body arranged on one side of the installation housing and is fixed by buckles or fasteners.

[0007] Further, the housing is injection molded from hard plastic, and a sub-frame and a sealing frame are further arranged on the housing.

[0008] Further, the frame is integrally formed with the equipment main body.

[0009] Further, when the valve plate falls into the receiving groove, the blocking step contacts the edge of the valve plate.

[0010] Further, the valve plate is made of silica gel material.

[0011] Further, the sound insulation cover is located on the side close to the floor after installation.

[0012] Further, a sealing strip is further arranged between the sound insulation cover and the installation housing.

[0013] Further, the vertical air valve for extending the water penetration time further comprises a water accumulation tank.

[0014] Further, the water accumulation tank is arranged on the same side of the installation housing as the sound insulation cover, and when the installation housing is installed on a vehicle, the water accumulation tank is located below the sound insulation cover.

[0015] Compared with the prior art, the vertical air valve for extending the water penetration time provided by the utility model makes the valve plate fall into the receiving groove when closed and is protected by the blocking step by arranging the receiving groove on the frame. When the vehicle wades through water, the water flow is prevented from directly impacting the valve plate, so that the valve plate floats up, and the water flow enters the vehicle through the gap via the ventilation opening. Through the blocking effect of the blocking step, the water penetration time is extended, and a reaction time is reserved for the reaction system inside the vehicle to react to the wading situation.

[0031] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0032] As Figures 1 to 15 shown, it is a schematic structural view of a vertical air valve for extending the water permeation time provided by the present invention. The vertical air valve for extending the water permeation time includes an installation housing 10, a plurality of valve plates 20 provided on the installation housing 10, and a sound insulation cover 30 provided on the installation housing 10. It can be conceived that the vertical air valve for extending the water permeation time further includes some other functional modules such as installation structures, sealing structures, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein one by one.

[0033] The housing 10 is made of hard plastic by injection molding and includes an installation port 11, a plurality of ventilation ports 12 provided on the installation port 11, a plurality of frames 13 forming the ventilation ports 12, and a plurality of valve plate fixing members 14 provided on the frames 13.

[0034] A secondary frame for installation and a sealing frame for ensuring installation tightness are also provided on the housing 10. The installation port 11, ventilation ports 12 and valve plate fixing members 14 have all been mentioned in the utility models already applied for by the applicant, such as an air circulation device applicable to an automobile with a publication number of CN202223377885.6, so they will not be elaborated herein one by one.

[0035] The housing 13 is integrally formed with the device main body to form the ventilation opening 12. A receiving groove 131 is provided on the housing 13. The receiving groove 131 is a sunken groove located on the contact surface between the housing 13 and the valve plate 20, and the groove size is larger than the size of the valve plate, so that when the valve plate 20 covers the housing 13, it falls into the receiving groove 131. One side of the receiving groove 131 communicates with the ventilation opening 12, and the other side forms a blocking step 132. The thickness of the blocking step 132 is greater than the thickness of the valve plate 20, and when the valve plate 20 falls into the receiving groove 131, it contacts the edge of the valve plate 20, so that when the ventilation opening 12 is closed, the valve plate 20 is located in the receiving groove 131. When the vehicle wades through water, the water entering the air valve will not immediately impact on the valve plate 20, but will first be blocked by the blocking step 132 to prevent the water flow from immediately entering the vehicle through the ventilation opening 12, so as to reserve time for the reaction system built in the vehicle to react to the wading situation.

[0036] The valve plate 20 is made of a flexible material such as silica gel and covers each ventilation opening 12. By opening an opening that matches the cross-sectional size of the valve plate fixing member 14, the valve plate 20 is sleeved on the valve plate fixing member 14 so that it can flip at the ventilation opening 12 and cannot be detached, so that when there is an air flow, the valve plate 20 is driven to flip up, and when there is no air flow, the valve plate 20 covers the ventilation opening 12 under the action of gravity, thereby realizing the one-way passage of the air flow.

[0037] The sound insulation cover 30 is a cover body provided on one side of the installation housing 10 and is fixed by means of buckles or fasteners, etc. to block the air flow and prevent noise generated by the high-speed passing of the air flow. The sound insulation cover 30 is provided at a partial position of the installation housing 10. Specifically, it is located on the side close to the floor after installation, so that while the sound insulation cover 30 blocks the high-speed air flow from directly passing through the ventilation opening 12, it does not prevent air circulation. Similarly, the position and shape of the sound insulation cover 30 can be designed according to the actual installation requirements of the installation housing 10. A sealing strip can also be provided between the sound insulation cover 30 and the installation housing 10 to ensure the sealing performance of the sound insulation cover.

[0038] Such as Figure 4 、 Figure 11 、 Figure 13As shown, the vertical air valve for extending the water penetration time further includes a water sump 40. The water sump 40 is arranged on the same side of the installation housing 10 as the sound insulation cover 30. When the installation housing 10 is installed on a vehicle, the water sump 40 is located below the sound insulation cover 30 to collect the water droplets generated by the collision of cold air and hot air when there is a temperature difference between the inside and outside of the vehicle. At the same time, when it is raining or the vehicle is being washed, the water sump can also collect the water vapor that enters the vehicle from the ventilation device due to the negative pressure inside the vehicle compartment. Of course, it can be imagined that the water stored in the water sump can be drained out of the vehicle body by a diversion structure, so as to avoid water falling into the vehicle compartment.

[0039] Compared with the prior art, the vertical air valve for extending the water penetration time provided by the present utility model has a receiving groove 131 provided in the frame body 13, so that the valve plate 20 will fall into the receiving groove 131 when it is closed and is protected by the blocking step 132. When the vehicle wades through water, the valve plate 20 is prevented from being directly impacted by the water flow, so that the valve plate 20 floats up and the water flow enters the vehicle through the gap via the ventilation opening 12. Through the blocking effect of the blocking step 131, the water penetration time is extended, leaving a reaction time for the reaction system built into the vehicle to respond to the wading situation.

[0040] The above is only a preferred embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. Any modification, equivalent replacement or improvement within the spirit of the present utility model is covered by the scope of the claims of the present utility model.
