A barbecue exhaust pipe anti-drip oil fitting

Abstract

This utility model relates to an anti-dripping oil fitting for barbecue exhaust ducts, specifically disclosing an anti-backflow oil fitting for barbecue exhaust ducts. It includes an exhaust pipe hood, an oil-blocking plate bracket inside the hood, an oil-blocking enclosure fixed to the top of the bracket, a central vent at the top of the enclosure, and an upper oil-blocking plate on the central vent. This anti-backflow oil fitting effectively prevents oil droplets from flowing back. By covering the central vent with the upper oil-blocking plate, it directly intercepts oil droplets condensing and dripping from above the duct. It guides the oil droplets to orderly collection; the upper oil-blocking plate guides the intercepted droplets to the enclosure, and then through the enclosure to the settling trough. It ensures smooth exhaust; the gap between the flared oil-blocking enclosure and the exhaust pipe hood, combined with the design of the central vent, achieves anti-dripping functionality. Installation is convenient and stable; with the help of the settling trough and the oil-blocking plate bracket, the fitting can be quickly installed and fixed.

Description

Technical Field

[0001] This utility model relates to the field of anti-dripping pipe fittings technology, specifically a large file concurrent upload system and method based on dynamic fragmentation strategy and resource optimization. Background Technology

[0002] Smoke extraction systems are crucial for ensuring a safe indoor environment for cooking and other activities. Whether in a home or a business, a smoke-free environment is essential. For example, the fumes produced when grilling meat in a barbecue restaurant contain a large amount of grease. As this grease flows through the exhaust duct, it gradually condenses into oil droplets due to the decreasing temperature. In commercial exhaust systems, retractable exhaust pipes are the most widely used. Traditional exhaust pipes, lacking a dedicated anti-dripping structure, allow condensed oil droplets to flow back along the inner wall of the pipe, dripping from the exhaust outlet onto the grilled food or countertops. This not only affects the hygiene and taste of the food but can also contaminate tables and floors, increasing cleaning burdens. Furthermore, long-term accumulation of dripping oil droplets at the bottom of the pipe poses a hygiene hazard and reduces the operating efficiency of the exhaust system, requiring frequent cleaning and maintenance, thus increasing the operating costs of the barbecue restaurant. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-drip oil fitting for barbecue exhaust pipes, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a barbecue exhaust pipe anti-drip oil accessory, including an exhaust pipe cover, an oil shield bracket provided on the inner side of the exhaust pipe cover, an oil shield enclosure fixed to the top of the oil shield bracket, a central air vent opened on the top of the oil shield enclosure, and an upper oil shield on the central air vent.

[0005] Preferably, the inner side of the exhaust pipe hood is provided with a recess for placing the oil shield bracket.

[0006] Preferably, the oil-shielding panel is trumpet-shaped.

[0007] Preferably, the upper oil shield is butterfly-shaped and covers the entire central air vent.

[0008] Preferably, the outer wall of the oil-shielding panel is uniformly fixed with protrusions.

[0009] Compared with the prior art, the beneficial effect of this utility model is that the anti-drip oil fitting for barbecue exhaust pipes is:

[0010] Effectively prevents oil droplets from flowing back: By covering the central air vent with the upper oil shield, oil droplets that condense and drip from above the pipe can be directly intercepted, preventing oil droplets from falling directly onto food or the countertop and ensuring hygiene and safety during the grilling process.

[0011] Guided oil droplet collection: The upper oil shield guides the intercepted oil droplets to the oil shielding plate, and then flows through the oil shielding plate to the settling tank, so that the oil droplets are collected in a concentrated manner, reducing the pollution of the inner wall of the pipeline and reducing the frequency and difficulty of pipeline cleaning.

[0012] Ensuring smooth smoke exhaust: The gap between the trumpet-shaped oil shield and the smoke exhaust pipe hood, combined with the design of the central air vent, achieves the function of preventing oil dripping while not significantly obstructing the flow of smoke, ensuring the normal operation and efficiency of the smoke exhaust system.

[0013] Easy and stable installation: With the cooperation of the settling tank and the oil shield bracket, the accessories can be quickly installed and fixed. The boss design can avoid the blockage problem caused by the oil shield coming into close contact with the inner wall of the pipe, thus improving the stability of use. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution:

[0023] A barbecue exhaust duct anti-drip oil fitting includes an exhaust pipe cover 1 installed at the air inlet of the exhaust pipe, and an oil shield bracket 2 for supporting an oil shield 3 is provided on the inner side of the exhaust pipe cover 1. The oil shield 3 is welded to the top of the outer wall of the oil shield bracket 2.

[0024] The top of the oil shielding plate 3 is provided with a central air vent 4. A certain gap is provided between the oil shielding plate 3 and the exhaust pipe hood 1. The flue gas enters the exhaust pipe hood 1 from the air inlet, and then passes through the gap between the oil shielding plate 3 and the exhaust pipe hood 1 and the central air vent 4 into the exhaust pipe.

[0025] An upper oil shield 5 is provided on the central air vent 4. The upper oil shield 5 is used to prevent oil droplets from dripping through the central air vent 4. After the oil droplets fall onto the upper oil shield 5, they are guided by the upper oil shield 5 to flow onto the oil shielding plate 3, and finally guided into the settling tank 7 through the oil shielding plate 3.

[0026] The inner side of the exhaust pipe hood 1 is provided with a recess 7 for placing the oil shield bracket 2. The recess 7 is designed to be circular, following the shape of the exhaust pipe hood 1.

[0027] The bottom of the oil shield bracket 2 is an annular steel ring, with centripetally inclined support rods evenly distributed on the outer circumference of the steel ring. The oil shield 3 is then welded to the support rods. To ensure normal flue gas passage, a central vent 4 is opened at the top of the oil shield 3, making the oil shield 3 flared. Installation only requires placing the annular steel ring into the settling trough 7 and then connecting the exhaust pipe hood 1 to the exhaust pipe.

[0028] The upper oil shield 5 is made of a circular steel plate, with both sides of the plate symmetrically bent upwards along a central diameter to form a butterfly shape, covering the entire central air vent 4. This ensures that the flue gas flowing through the central air vent 4 is not obstructed by the oil shield 5.

[0029] The outer wall of the oil-shielding panel 3 is uniformly fixed with protrusions 6 that are higher than the surface of the outer wall of the oil-shielding panel 3. When the smoke is heavy, the air velocity inside the exhaust duct will often increase, which may suck up the accessories and block the duct over a large area. In order to ensure the ventilation effect, the protrusions 6 that are higher than the surface of the outer wall of the oil-shielding panel 3 can prevent the oil-shielding panel 3 from coming into close contact with the inner wall of the exhaust duct plug.
