Description
Technical Field
[0001] The utility model relates to the technical field of passenger car drainage, in particular to a passenger car luggage compartment drainage valve. Background Art
[0002] The luggage compartment drain valve for passenger cars currently on the market uses the most common cylindrical single-port drain valve, which only includes one vertical channel and is equipped with a sealing plug. When draining, the sealing plug is opened to drain the water. Since the space in the luggage compartment is relatively closed, the air pressure inside and outside the single-channel drain valve is not easy to balance. The air pressure difference between the inside and outside will affect the drainage efficiency, causing the drainage to become slower, and the debris in the luggage compartment will flow into the pipe, causing blockage over time, making it difficult to unclog the valve body.
[0003] In addition, current drain valves are usually purchased from the market, and the materials of drain valves are mostly a combination of plastic and metal materials. Metal materials are prone to corrosion over time and have poor durability, while plastic materials are not easy to stably connect to the vehicle body.
[0004] Based on the above reasons, it is necessary to design a new drain valve that has higher drainage efficiency than the traditional drain valve, is not easily disturbed by the air pressure difference, has a longer service life, and can filter out impurities from the passenger car luggage compartment drain valve. Utility Model Content
[0005] The utility model aims to address the deficiencies of the prior art and thus provide a passenger car luggage compartment drain valve with higher drainage efficiency, longer service life and filtering effect.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a passenger car luggage compartment drain valve, including an integrally formed valve body, the material of the valve body is rubber, and the valve body includes an assembly part, a connecting part and a main body;
[0007] The assembly portion is provided with an annularly distributed convex edge and a clamping groove arranged immediately below the convex edge, and the enclosed center of the convex edge forms a water inlet;
[0008] The connecting portion is used to connect the assembly portion and the main body, and a cavity communicating with the water inlet is formed in the assembly portion, the connecting portion and the main body;
[0009] The main body comprises a tapered head with a gradually narrowed end and a plurality of ribs formed outside the tapered head, wherein the ribs extend along the length direction of the valve body and converge at the end of the main body;
[0010] At least one water outlet is arranged in each of the ribs, the inner end of the water outlet penetrates the cone head and communicates with the cavity, and the outer end of the water outlet forms a long hole on the end surface of the rib.
[0011] Based on the above, the length of the water outlet gradually increases from the inner end opening to the outer end opening.
[0012] Based on the above, each of the ribs is provided with two water outlets, the inner end opening of the first water outlet is provided at the vertical section of the cone head, and the outer end opening extends from the vertical section of the rib to the middle of the inclined section; the inner end opening of the second water outlet is provided at the cone angle section of the cone head, and the outer end opening is provided at the end of the inclined section of the rib near the end where it gathers.
[0013] Based on the above, the water outlet direction of each of the first water outlets is generally in an umbrella-shaped direction extending from the center to the surrounding areas obliquely downward.
[0014] Based on the above, the water outlet direction of each of the second water outlets is parallel to the axial direction of the drain valve.
[0015] Based on the above, the end gathering areas of each of the ribs are connected as one.
[0016] Based on the above, the convex edge includes an annular body, and a plurality of notches are formed on the annular body at equal intervals.
[0017] Based on the above, the number of the ribs is four, and the four ribs are arranged at equal angles on the outer side of the cone head.
[0018] Based on the above, the valve body is a one-piece rubber structure formed by vulcanization.
[0019] Based on the above, a sealing gasket ring is arranged in the slot.
[0020] Compared with the prior art, the utility model has substantial characteristics and progress. Specifically, the utility model changes the traditional straight-through valve body and changes it to a cone head shape, and arranges a plurality of ribs at the outer end of the cone head. The water outlet is opened based on the ribs, and the inner end of the water outlet is connected with the drain valve cavity, and the outer end serves as the outlet end. Due to the expansion of the size of the ribs, the outlet end formed at the outer end of the water outlet can be designed as a long hole, and the inner end size of the water outlet is smaller than the outer end size. When draining water, the water flow is dispersed when entering the drain outlet, and it is not easy to close the drain outlet, and it is not easy to cause the formation of internal and external pressure difference. Moreover, the increase in the number of water outlets and the diverse design of the orientation also improve the drainage efficiency, and work together to solve the interference problem caused by the pressure difference.
[0021] Since the overall material of the drain valve is made of one-piece rubber material, which is consistent with the main material composition of the luggage compartment, it only needs to be clamped during assembly. With the help of the flexibility of rubber, good installation stability and sealing can be achieved, thereby extending the life and service life of the drain valve itself.
[0022] Since the water outlets are dispersed, forming numerous narrow and long hole-shaped water outlets, a funnel with filtering performance is naturally formed in the main body, isolating the impurities in the luggage compartment inside the main body. The staff only needs to clean the main body regularly, and there is no need to worry about blockage inside the water outlet, and the difficulty of unblocking is relatively low.

[0029] The technical solution of the utility model is further described in detail below through specific implementation methods.
[0030] like Figure 1-Figure 5 As shown, a luggage compartment drain valve for a passenger car includes an integrally formed valve body. The valve body is made of rubber and is integrally formed by NR vulcanization. The valve body includes an assembly portion 1, a connecting portion 2 and a main body 3.
[0031] The assembly portion 1 is provided with an annularly distributed convex edge 11 and a clamping groove 12 arranged immediately below the convex edge 11 , and the enclosed center of the convex edge 11 forms a water inlet 13 .
[0032] In this embodiment, the flange 11 includes an annular body, on which a plurality of slots are evenly spaced to form a flange 11 with a multi-petal structure. The purpose of such design is to improve the adaptability of the flange area during assembly. The slot design allows each petal of the multi-petal structure to be flexibly adjusted, thereby avoiding interference caused in certain directional spaces during assembly.
[0033] The card slot 12 is usually used to lock with the card slot set in the water outlet area of the luggage compartment. In some cases where higher sealing requirements are required, a sealing gasket 14 can also be added to the card slot 12. After adjusting the size of the assembly port, a fully sealed connection with the luggage compartment can be achieved.
[0034] The connecting portion 2 is used to connect the assembly portion 1 and the main body 3. The assembly portion 1, the connecting portion 2 and the main body 3 form a cavity 4 connected to the water inlet 13. The cavity 4 is cylindrical as a whole and is adapted to the main body to form a cone at the bottom.
[0035] The main body 3 includes a cone head 31 with a gradually narrowed end and a plurality of ribs 32 formed outside the cone head 31. The ribs 32 extend along the length direction of the valve body and gather at the end of the main body 3. In this embodiment, the end gathering areas of each rib are connected as a whole. The integrated ribs 32 can also enhance the structural strength of the drain valve to a certain extent.
[0036] At least one water outlet 33 is disposed in each of the ribs 32 . The inner end of the water outlet 33 penetrates the cone head 31 and communicates with the cavity 4 . The outer end of the water outlet 33 forms a long hole on the end surface of the rib 32 .
[0037] Specifically, in this embodiment, the number of the ribs 32 is four, and the four ribs 32 are arranged at equal angles on the outside of the cone head 31. The length of the water outlet 33 gradually increases from the inner end opening to the outer end opening, that is, a narrow slit channel that is narrow inside and wide outside is formed.
[0038] In this embodiment, two water outlets are provided in each of the ribs 32, the inner end opening of the first water outlet 331 is provided in the vertical section of the cone head, and the outer end opening extends from the vertical section of the rib to the middle of the inclined section; the water outlet direction of each of the first water outlets 331 is generally in an umbrella-shaped direction extending from the center to the surrounding oblique downward direction, and the water will also be discharged outward along the umbrella-shaped direction. Since the size of the outlet end is enlarged, the air is not easily blocked, and the outside air can always break through the water outlet and enter the interior. The gas pressure inside and outside can be continuously balanced with the drainage, thereby ensuring the drainage efficiency.
[0039] The inner opening of the second water outlet 332 is arranged at the cone angle section of the cone head 31, and the outer opening is arranged at the end of the inclined section of the rib near the end where it gathers. The water outlet direction of each of the second water outlets 332 is parallel to the axial direction of the drain valve, and is vertical drainage in the assembled state, which is different from the drainage direction of the first water outlet 331, and complements interference.
[0040] Working principle description:
[0041] When the inner sealing plug or channel plug of the drain valve is opened, the fluid enters the cavity 4 through the water inlet 13, and then is discharged outward along the eight water outlets 33 distributed around the cavity 4. Since the inner end size of each water outlet is smaller than the outer end size, a narrow slit channel with a narrow inside and a wide outside is formed, and the water flow discharged outward cannot fill the channel of the water outlet. The air can always enter the cavity 4 through the water outlet, and then further enter the luggage compartment, ensuring the balance of internal and external pressures, so that the drainage efficiency is not easily affected by the air pressure difference.
[0042] It should be noted that this technology may fail when the water volume is too large, but it has good effects under normal working conditions.
[0043] Furthermore, since the water outlet is in the shape of a narrow slit, the valve naturally forms a filtering structure, and impurities are isolated in the cavity 4 when flowing through the water outlet. It only needs to clean the cavity 4 regularly, and the labor intensity is greatly reduced compared to disassembling and cleaning the drain valve.
[0044] Since rubber is used as the material, which is the same as the material of most of the vehicle's lining structures, no metal connectors are required during assembly to achieve a relatively closed sealing effect and ensure service life.
[0045] Finally, it should be noted that: The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
