Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust outlet technology, and more specifically to a remote-controlled multi-blade smoke exhaust outlet. Background Technology

[0002] Smoke vents are openings located on the exterior walls or roofs of buildings, either automatically or manually, to expel smoke and heat generated during a fire. There are two main types of smoke vents: panel smoke vents and multi-leaf smoke vents. Depending on whether they have an electric actuator, multi-leaf smoke vents can be further divided into those with and without remote control devices. Current remote control technology often uses a remote control module linked to a corresponding electric actuator.

[0003] While existing remote-controlled multi-leaf exhaust vents can remotely control the opening or closing of individual leaves for smoke exhaust, liquid oil accumulates inside after prolonged use. Traditional remote-controlled multi-leaf exhaust vents require periodic cleaning, which necessitates disassembly to check for liquid oil, resulting in mediocre performance. To further improve the overall performance of exhaust vents, the inventors proposed this solution. Utility Model Content

[0004] The purpose of this utility model is to provide a remote-controlled multi-blade smoke exhaust outlet in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A remote-controlled multi-blade smoke exhaust outlet includes a housing, a multi-blade assembly, an external filter, an internal filter, a fan assembly, and a bottom groove. The external filter is nested on the right side of the housing, and the internal filter is installed parallel to the inner side of the external filter. The fan assembly includes fan blades, a motor, and a mounting bracket. The mounting bracket is locked inside the housing and has the internal filter mounted on it. The motor is locked to the mounting bracket, and its output end is connected to the fan blades. The fan blades are located between the internal and external filters. Several flow ports are provided at the bottom of the housing, and the bottom groove is installed below the flow ports.

[0007] The fan blades are fan-shaped for ventilation, meaning that when the fan blades are driven to rotate, the fan draws outside air into the interior. The external filter is directly installed on the right side of the casing. It is the first filtration structure in the multi-blade exhaust port structure for treating flue gas from the external environment. Together with the internal filter, it forms a dual filtration structure.

[0008] A preferred technical solution: The multi-leaf assembly includes a telescopic rod, a linkage rod, a sliding groove, a spring, a connecting rod, and a single leaf. The single leaf is hinged to the outer shell. The telescopic rod is connected to the side end of the linkage rod through a connecting plate. The linkage rod slides up and down along the sliding groove, and a spring is installed in the sliding groove. The linkage rod is hinged to the connecting rod, and the connecting rod is hinged to the single leaf.

[0009] The telescopic rod controls the displacement of the linkage rod, causing the linkage rod to hinge to the connecting rod, which in turn hinges to individual leaflets. Each leaflet, with its hinge point to the outer shell as its rotation point, rotates at a certain angle to open or close multiple leaflets simultaneously. A sliding groove surrounds the outer end of the linkage rod, improving the accuracy of its vertical movement. The spring within the sliding groove enhances the automatic reset effect of the linkage rod, reducing the load on the telescopic rod. Two sliding grooves are provided; whether or not springs are included within the grooves is flexibly determined based on usage requirements.

[0010] A preferred technical solution: A wind guide plate is provided at the side end of the telescopic rod.

[0011] A preferred technical solution: The mounting bracket has several through openings.

[0012] A preferred technical solution: A transparent panel is provided at the end of the bottom groove facing the multi-leaf component.

[0013] A preferred technical solution: Two flow ports are provided, one located between the fan assembly and the external filter plate, and the other located between the fan assembly and the multi-blade assembly.

[0014] A preferred technical solution: the connecting rod and the sliding groove are staggered.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model features a remote-controlled multi-blade exhaust vent with a bottom groove at the bottom of the outer casing and a transparent panel at the outer end of the groove. Liquid oil stains from different locations can flow directly into the bottom groove for collection through the flow port. Compared to accumulation on the inner bottom surface of the outer casing, bottom groove collection effectively increases the collection volume. The bottom groove can be pulled out for direct cleaning, reducing cleaning difficulty and improving cleaning efficiency. This utility model uses a combination of built-in and external filters to ensure filtration effectiveness. The overall combination of the remote-controlled multi-blade exhaust vent and its comprehensive application results in good performance. Attached Figure Description
