Description

One-piece air outlet device with single check valve applied to smoking machine

technical field

The utility model relates to an auxiliary device for a smoke machine, in particular to a single check valve conjoined air outlet device applied to a smoke machine.

Background technique

Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the healthy and energy-saving range hood stove in the kitchen. It can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. The range hood is mainly composed of an organic shell, an air duct, a fan, a check valve, an oil collection and discharge device, a lighting device, a power switch and a power cord. The existing check valve air outlet device has high cost and complicated installation, so it is necessary to design a single check valve conjoined air outlet device applied to the hood.

Contents of the invention

Aiming at the deficiencies in the prior art, a single-check-valve conjoined air outlet device applied to a hood is provided.

The utility model is realized through the following scheme: a single-check valve conjoined air outlet device applied to a smoke machine, the device includes an air outlet body with a hollow cavity structure, and a semicircle is arranged on the upper part of the air outlet body. A shaped air outlet and a semicircular panel, the air outlet and the panel form a circle, a check valve is correspondingly provided on the air outlet, and air inlets are symmetrically arranged on both sides of the lower part of the air outlet ;

The air outlet body includes an integrally formed first connecting unit and an integrally formed second connecting unit, and the first connecting unit and the second connecting unit are connected by connecting bolts.

An air inlet grill is arranged on the air inlet.

The check valve has a semicircular structure, and the check valve matches the air outlet.

The beneficial effects of the utility model are:

The utility model is a one-piece air outlet device with a single check valve applied to a smoke machine. On the premise of not changing the performance of the air outlet device, the traditional double check valve is changed into a single check valve, and the area of the air outlet is reduced. to a semicircle, reducing material costs. The air outlet body includes an integrally formed first conjoined unit and an integrally formed second conjoined unit, which are connected by bolts, which simplifies the installation procedure and improves efficiency.

In the figure: 1 is the connecting bolt, 2 is the first connecting unit, 3 is the second connecting unit, 4 is the air outlet, 5 is the air outlet, 6 is the check valve, 7 is the air inlet, 8 is the air inlet grille, 9 is a panel.

Detailed ways

The preferred embodiment of the utility model is further described below in conjunction with the accompanying drawings. A single-check valve conjoined air outlet device applied to a smoke machine, the device includes an air outlet body 4 with a hollow cavity structure, and the air outlet body The upper part of 4 is provided with a semicircular air outlet 5 and a semicircular panel 9, the air outlet 5 and the panel 9 form a circle, and a check valve 6 is correspondingly provided on the air outlet 5. Both sides of the lower part of the air outlet body 4 are symmetrically provided with air inlets 7 .

The air outlet body 4 includes an integrally formed first connecting unit 2 and an integrally formed second connecting unit 3, the first connecting unit 2 and the second connecting unit 3 are connected by connecting bolts 1 to form a hollow cavity The air outlet body 4 of body structure. An air inlet grill 8 is provided on the air inlet 7, and impurities are removed through the air inlet grill to prevent subsequent steps from being affected. The check valve 6 has a semicircular structure, and the check valve 6 is matched with the air outlet 5, and when the check valve is closed, it is completely matched with the air outlet. The specific principles and technical features of the implementation of the check valve 6 are known technologies, and will not be repeated here.

In actual use, the air outlet is connected to the external corrugated smoke pipe. When the machine is turned on, the fan starts, and the oil fume or air volume enters the air from the air inlet side, and the check valve opens. When it is closed, the check valve automatically closes due to gravity. . The utility model is a one-piece air outlet device with a single check valve applied to a smoke machine. On the premise of not changing the performance of the air outlet device, the traditional double check valve is changed into a single check valve, and the area of the air outlet is reduced. to a semicircle, reducing material costs. The air outlet body includes an integrally formed first conjoined unit and an integrally formed second conjoined unit, which are connected by bolts, which simplifies the installation procedure and improves efficiency.

Although the technical solutions of the present utility model have been elaborated and enumerated in detail, it should be understood that for those skilled in the art, it is necessary for those skilled in the art to make modifications to the above-mentioned embodiments or adopt equivalent alternatives. It is obvious that these modifications or improvements made on the basis of not departing from the spirit of the utility model all belong to the protection scope of the utility model.
