Description

TECHNICAL FIELD

[0001] The utility model relates to a ventilation and air conditioning system field, specifically is a kind of air outlet ventilation indicating device. BACKGROUND

[0002] Fresh air system is the key component in indoor ventilation and air conditioning system, and the fresh air system is usually composed of fresh air machine and air outlet, wherein the fresh air machine is responsible for sucking air from outdoor, and after filtering, purification, heating or cooling treatment, the fresh air is sent into indoor;The air outlet is the terminal component for distributing fresh air to indoor space, and as the "display window" of system operation, the normality of air outlet directly affects the flow and quality of indoor air.

[0003] The existing fresh air system is relatively traditional and simple in air outlet operation state indication. Usually, people cannot easily judge whether fresh air blows into the air outlet through the appearance or state of the air outlet itself. Therefore, some users or installers will tie a red ribbon at the air outlet to judge the ventilation state of the air outlet by observing whether the ribbon is fluttering.

[0004] However, the above-mentioned method has obvious defects:

[0005] 1) Aesthetics is affected: a ribbon is directly hung or tied on the air outlet, which does not meet the aesthetic requirements of modern indoor decoration and is not professional enough.

[0006] 2) Installation and maintenance are inconvenient: additional secondary processing (tying ribbon) is needed after the product is shipped, which increases the installation steps and time.

[0007] 3) It is difficult to accurately judge the laminar flow state: when the air flow velocity of the air outlet is stable and forms laminar flow, the ribbon may be in a nearly static state, making it difficult for the observer to judge the air outlet state. At this time, even if there is fresh air flowing out slowly and stably, the ribbon cannot effectively flutter, causing false appearance. INVENTION CONTENTS

[0008] The utility model aims at solving the problems in the prior art, and provides an air outlet ventilation indicating device, which realizes visual indication of air outlet state by wind power generation.

[0009] To achieve the above-mentioned purpose, the following technical solutions are used:

[0010] An air outlet ventilation indicating device, comprising LED lamp arranged on the air outlet body and wind power generation assembly arranged in the air outlet body, wherein the wind power generation assembly supplies power to the LED lamp.

[0012] Preferably, the wind power generation assembly comprises a generator and a fan blade installed on a rotating shaft of the generator.

[0013] Preferably, the front end of the air outlet body is provided with an end cover with a plurality of air holes, the generator is installed at the middle of the inner side of the end cover, and the fan blade is located on the side of the generator away from the end cover.

[0014] Preferably, the generator and the LED lamp are electrically connected through wires.

[0015] Preferably, the generator is a micro generator.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] 1. The utility model integrates a set of wind power generation assembly and LED lamp on the air outlet, directly converts the strength of the air outlet state into the change of the brightness of the LED, can realize the indication of the working state of the LED light source driven by the wind power, and can realize the visual indication of the air outlet state without damaging the original equipment structure and the aesthetic degree.

[0019] 3. The utility model can directly and visually indicate the air outlet state, provides the real-time and intuitive air outlet state indication for the user through the brightness change of the LED lamp. When the air outlet amount increases, the brightness of the LED increases, when the air outlet amount decreases, the brightness of the LED decreases, and the LED is extinguished when there is no wind. Compared with the traditional method of observing the floating degree by binding a ribbon, the visual signal is more beautiful and clear, and the observation error is reduced.

[0021] 5. The sensitivity and the reliability of the utility model are high, when the air outlet approaches the laminar flow state, the traditional ribbon indication method fails due to the unobvious floating. The utility model can still effectively indicate the air outlet state by using the weak change of the brightness of the LED, enhances the recognizability under the condition of low air quantity or stable airflow, and thus improves the sensitivity and the reliability of the indication.

[0022] 6, The utility model discloses a ventilation indication utilizes the surplus energy of air outlet and has the characteristic of " zero additional consumption " of energy. The function of air outlet state indication is realized without introducing external power, which is beneficial to energy saving and environmental protection and embodies the innovation of product in the green design thought.
