Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe connector technology, and in particular to a double-diameter flat-mouth exhaust pipe connector. Background Technology

[0002] The exhaust duct connector connects to the portable air conditioner via the exhaust duct, which can be placed in a vehicle or indoors. However, existing exhaust duct connectors are only compatible with a single pipe diameter and cannot accommodate the two common exhaust duct sizes of 130mm and 150mm, thus preventing flexible selection of internal or external connection methods based on the installation environment. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the existing exhaust pipe connectors in the background technology are only compatible with a single pipe diameter and cannot be compatible with the two common exhaust pipe specifications of 130mm and 150mm on the market. As a result, they cannot flexibly choose the internal or external connection method according to the installation environment. Therefore, a dual-diameter flat-mouth exhaust pipe connector is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a double-diameter flat-mouth exhaust pipe connector, comprising a connector, a first exhaust pipe, and a second exhaust pipe, wherein one end of the connector is a flat interface, the outer surface of the interface is provided with an outer spiral pattern, and the inner surface of the interface is provided with an inner spiral groove.

[0005] As a further embodiment of this utility model, the diameter of the first exhaust pipe is 130mm and the diameter of the second exhaust pipe is 150mm.

[0006] As a further embodiment of this utility model, the flat opening of the interface has a width of 26cm and a height of 2.5cm.

[0007] As a further embodiment of this utility model, the interface is provided with a 15° inclined guide plate inside, and the number of the guide plates is 3, which are evenly distributed along the circumference of the inner wall of the interface.

[0008] As a further embodiment of this utility model, the thread spacing between the outer spiral groove and the inner spiral groove is 2mm and the thread depth is 1.5mm.

[0009] As a further improvement of this utility model, an annular sealing ring is provided at the connection between the No. 1 exhaust pipe and the No. 2 exhaust pipe and the interface.

[0010] The beneficial effects of the double-diameter flat-mouth exhaust pipe connector proposed in this utility model are as follows:

[0011] 1. With its dual design of external and internal spiral patterns, it can flexibly adapt to the two mainstream exhaust pipe specifications of 130mm and 150mm on the market, without the need for additional adapters, reducing the user's purchase and replacement costs.

[0012] 2. The flat interface, combined with the glass pressing and fixing method of the car frame / door frame, requires no drilling or auxiliary tools and is suitable for quick installation in multiple scenarios such as car interiors and indoor spaces.

[0013] 3. The design of the annular sealing ring effectively reduces air leakage and noise problems, improving user comfort.

[0014] 4. The 15° design of the deflector reduces wind resistance, minimizes turbulence, and significantly improves exhaust efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] A dual-diameter flat-mouth exhaust duct connector includes a connector 1, a primary exhaust duct 5, and a secondary exhaust duct 6. One end of the connector 1 is a flat interface 2. The outer surface of the interface 2 is provided with external spiral threads 3, and the inner surface of the connector 2 is provided with an internal spiral groove 4. The connector 1 is made of flame-retardant ABS plastic. The diameter of the primary exhaust duct 5 is 130mm, and the diameter of the secondary exhaust duct 6 is 150mm. One end of the primary exhaust duct 5 is inserted into the outside of the interface 2. Then, the thread on the outer surface of the primary exhaust duct 5 engages with the internal spiral threads 4 inside the interface 2, and the connection is achieved by rotation. Figure 2 As shown, or take out the No. 2 exhaust pipe 6 with a diameter of 150mm, insert one end of it into the outside of the interface 2, and mate it with the external spiral thread 3 on the outside of the interface 2. The connection is achieved by rotating it. Figure 3 As shown, it is compatible with two common exhaust pipe sizes on the market: 130mm and 150mm.

[0022] Furthermore, the flat opening of the interface 2 has a width of 26cm and a height of 2.5cm. The interior of the interface 2 is provided with a 15° inclined guide plate. There are 3 guide plates, which are evenly distributed along the inner wall of the interface 2 to divert gas and reduce turbulence. The golden ratio design of the flat opening size of 26cm in width and 2.5cm in height ensures exhaust efficiency while reducing wind resistance, thus ensuring sealing and preventing installation damage.

[0023] Next, the thread pitch between the outer spiral groove 3 and the inner spiral groove 4 is 2mm and the thread depth is 1.5mm. Furthermore, annular sealing rings are provided at the connections between the first exhaust pipe 5 and the second exhaust pipe 6 and the interface 2; the sealing rings are made of silicone.

[0024] Working principle: Insert one end of exhaust pipe 5 into the outside of interface 2. Then, the thread on the outer surface of exhaust pipe 5 engages with the internal thread 4 inside interface 2, and the connection is achieved by rotation. Figure 2 As shown, or take out the No. 2 exhaust pipe 6 with a diameter of 150mm, insert one end of it into the outside of the interface 2, and mate it with the external spiral thread 3 on the outside of the interface 2. The connection is achieved by rotating it. Figure 3 As shown, it is compatible with two common exhaust pipe specifications, 130mm and 150mm. The other end of exhaust pipe 5 or exhaust pipe 6 is connected to the portable air conditioner. When the portable air conditioner is in the car, the flat connector 2 is placed on the top of the car frame and then the glass is raised to fix the connector 2. If it is placed indoors, the connector 2 is placed on the door frame and then the glass is pushed to fix it.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
