Description

Technical Field

[0001] This utility model relates to the field of ventilation fan technology, specifically to a building energy-saving ventilation device. Background Technology

[0002] In modern built environments, indoor air quality has a crucial impact on the health and comfort of residents. Traditional ventilation systems primarily function to exchange indoor and outdoor air, improving air circulation, reducing indoor carbon dioxide concentration, and removing odors and harmful gases. However, these traditional ventilation systems are relatively limited in function, only capable of performing basic air exchange tasks.

[0003] In practical use, people not only require fresh indoor air but also a pleasant scent. For example, in residences, hotels, shopping malls, and other places, people expect to smell a subtle fragrance upon entering, creating a comfortable and pleasant atmosphere. However, existing ventilation systems cannot meet this need. To achieve air fragrance, separate fragrance devices are usually required, which not only increases the purchase cost and space required but also presents challenges in coordinating the operation of different devices. For instance, inconsistent operating times may lead to a mismatch between air freshness and fragrance effects. Therefore, developing an energy-saving ventilation fan device that integrates ventilation and fragrance functions is of significant practical importance. Utility Model Content

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This building energy-saving ventilation system integrates a fragrance diffuser into the ventilation fan mechanism, achieving functional fusion and innovation. During ventilation, the drive motor rotates the fan blades, and outdoor air enters the room after being filtered through a honeycomb mesh panel. The honeycomb mesh effectively blocks debris, ensuring air cleanliness and normal equipment operation. The fragrance diffuser adds scent to the air during ventilation. A miniature air pump uses air pressure to deliver perfume from a perfume bottle to the supply pipe, and then sprays it out through atomizing nozzles to mix with the air, improving indoor air quality and user experience. When fragrance is no longer needed, simply turning off the miniature air pump restores the air to an odorless state, making operation flexible and convenient. It achieves efficient ventilation while meeting users' personalized needs for air odor. Attached Figure Description

[0018] Example 3: A building energy-saving ventilation device, comprising a ventilation fan mechanism 1 and a fragrance mechanism 2, wherein the fragrance mechanism 2 is fixed to the bottom side wall of the inner cavity of the ventilation fan mechanism 1. In the ventilation fan mechanism 1, the front and rear ports of the square frame 1-1 correspond to the outdoor and indoor areas respectively. A honeycomb mesh plate 1-2 with honeycomb mesh holes is fixed to the rear port, and a fixing plate 1-6 is fixed to the front port. A drive motor 1-3 is fixed to the rear side of the fixing plate 1-6 by four brackets 1-4. The output shaft of the drive motor 1-3 is connected to the fan blade 1-5. An air flow opening is provided in the center of the fixing plate 1-6, and an air supply grille 1-7 is fixed to the front side by hand-tightening screws. Regarding the fragrance mechanism 2, the perfume bottle 2-4 is fixed to the bottom of the inner cavity of the square frame 1-1 via the base frame 2-1. A micro air pump 2-2 is fixed on the left side, and its air supply end enters the perfume bottle 2-4 through a metal tube. There is a component 2-3 for adding perfume on the left end face. A crossbeam 2-5 is fixed to the top via a metal frame, and an infusion tube 2-6 is fixed on the crossbeam 2-5. Five atomizing nozzles 2-7 are fixed at equal intervals on the top of the infusion tube 2-6. The right side is connected to the perfume bottle 2-4 via the infusion tube 2-8. During use, the drive motor 1-3 is turned on, and the fan blades 1-5 rotate to ventilate. When fragrance is needed, the micro air pump 2-2 is turned on, and the perfume is sprayed out through the atomizing nozzles 2-7 and mixed with the air. When not needed, the micro air pump 2-2 is turned off, and the air circulates without odor.

[0019] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: First, the drive motor 1-3 in the ventilation fan mechanism 1 is started. The output shaft of the drive motor 1-3 begins to rotate, driving multiple fan blades 1-5 to rotate. Since the rear port of the square frame 1-1 faces outdoors and the front port faces indoors, the rotation of the fan blades 1-5 will create airflow within the square frame 1-1, drawing in fresh outdoor air through the honeycomb mesh plate 1-2 fixed at the rear port. The multiple honeycomb mesh holes inside the honeycomb mesh plate 1-2 can block debris from entering, preventing debris from damaging internal parts or affecting air quality. After entering the square frame 1-1, the air continues to flow forward, passing through the central area of ​​the fixed plate 1-6 for air circulation. The air is introduced into the room through the opening and then through the air supply grille 1-7 fixed to the front surface of the fixed plate 1-6, realizing the exchange of indoor and outdoor air. During this process, the four supports 1-4 fixed in a ring array on the rear side wall of the fixed plate 1-6 play a role in stabilizing and supporting the drive motor 1-3. When it is necessary to add fragrance to the flowing air, the micro air pump 2-2 in the fragrance mechanism 2 is turned on. The air supply end of the micro air pump 2-2 passes through a metal tube into the inner cavity of the perfume bottle 2-4. The air pressure is used to squeeze the perfume inside the perfume bottle 2-4 into the liquid supply tube 2-8 fixedly connected on the right. The perfume in the liquid supply tube 2-8 then flows into the infusion tube 2-6 fixedly connected at the top, and finally flows out from the 3 fixed at equal distances at the top of the infusion tube 2-6. Five atomizing nozzles 2-7 spray fragrance into the air, mixing it with the air flowing through the room. A perfume addition component 2-3 fixed to the left end face of the perfume bottle 2-4 allows for adding perfume when needed. A base frame 2-1 fixed to the bottom surface of the perfume bottle 2-4 stably secures the perfume bottle 2-4 to the bottom surface of the inner cavity of the square frame 1-1. A metal frame fixed to the top surface of the perfume bottle 2-4 is used to fix the crossbeam 2-5, ensuring the stability of the crossbeam 2-5 and the infusion tube 2-6 and other components fixed on it. When it is not necessary to add fragrance to the air, the micro air pump 2-2 is turned off, the perfume in the perfume bottle 2-4 is no longer squeezed out, the atomizing nozzles 2-7 stop spraying perfume, and the air flowing through the device returns to an odorless state.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
