[0023] Please refer to Figure 1 and Figure 2 The present invention provides a fresh air handling unit 10, which may include a fan 11 and an ion generator 12. The fresh air handling unit 10 may form a fresh air duct 13. The fresh air duct 13 may have an air inlet 131 and an air outlet 132. The fan 11 is adapted to generate an airflow within the fresh air duct 13 from the air inlet 131 to the air outlet 132. The ion generator 12 is disposed within the fresh air duct 13 near the air outlet 132. The ion generator 12 is adapted to purify the air located at the air outlet 132.

[0024] The aforementioned fresh air handling unit 10, by placing the ion generator 12 in the fresh air duct 13 near the air outlet 132, allows the newly introduced outdoor air to immediately come into full contact with and mix with ions after passing through the fresh air handling unit 10, so that the ions reach the highest concentration the moment they enter the room, achieving instant purification, and can avoid secondary pollution of the air by pollutants (such as bacterial growth) in the duct.

[0025] Specifically, please combine Figure 1 In some cases, the fresh air handling unit 10 may include a housing 14. The housing 14 can be enclosed to form a fresh air duct 13. An air inlet 131 and an air outlet 132 are formed on the housing 14 and are connected through the fresh air duct 13.

[0026] Additionally, please combine Figure 1 In some cases, the fan 11 can draw in air into the fresh air handling unit 10 and discharge air to the location of the air outlet 132, thereby forming an airflow from the air inlet 131 to the air outlet 132 within the fresh air duct 13. Alternatively, the duct within the fan 11 can constitute part of the fresh air duct 13, and correspondingly, the inner wall of the fan 11 that forms the duct can also serve as the inner wall of the fresh air duct 13. In other cases, the fan 11 can be located outside the casing 14, and positive pressure can be applied at the air inlet 131, or negative pressure can be applied at the air outlet 132, causing an airflow from the air inlet 131 to the air outlet 132 to be formed within the fresh air duct 13.

[0027] Please refer to Figure 2 and Figure 3 In some cases, at least two ion generators 12 may be spaced apart on the inner wall of the fresh air duct 13 around the axial direction of the air outlet 132.

[0028] In this way, ions can be released from multiple positions and angles into the air passing through the air outlet 132, which can uniformly purify the air and thus improve the purification effect.

[0029] Specifically, in Figure 2 and Figure 3 In this diagram, the central axis of the air outlet 132 can be represented as L, and the direction of the central axis L is the axial direction of the air outlet 132. Figure 3 In the middle, four ion generators 12 are arranged at intervals around the central axis L in the fresh air duct 13, and can release ions into the fresh air duct 13.

[0030] Understandable, Figure 3Based on this, different ion generators 12 can release ions at different locations and at different angles, which allows the released ions to be distributed as evenly as possible in the air at the air outlet 132, thereby improving the air purification effect.

[0031] In some cases, the fresh air handling unit 10 may include a mounting bracket (not shown). The mounting bracket may be positioned at the air outlet 132. The ion generator 12 is adapted to be mounted on the mounting bracket at or near the center of the air outlet 132.

[0032] In this way, the ion generator 12 can release ions near the center of the air outlet 132 to purify the air and improve the purification effect.

[0033] Specifically, in such a case, one end of the fixed bracket is fixedly connected to the inner wall of the fresh air duct 13, and the other end extends to the central area of ​​the air outlet 132. The ion generator 12 can be installed on the other end, which allows the ion generator 12 to be located or as close as possible to the center of the air outlet 132.

[0034] It is understandable that the ion generator 12 can release ions in all directions. When the ion generator 12 is located in the center of the air outlet 132, the ions released by the ion generator 12 can come into contact with more air. In this way, the ions can be mixed in the air as evenly as possible, thereby improving the air purification effect.

[0035] Please combine Figure 4 In some cases, the distance between the ion generator 12 and the air outlet 132 along the axial direction of the air outlet 132 is not less than 10 cm.

[0036] This avoids situations where the airflow is too fast and the air is not sufficiently purified.

[0037] Specifically, in Figure 4 In the diagram, the distance between the ion generator 12 and the air outlet 132 can be represented as D.

[0038] When air passes through the air outlet 132, due to the inherent velocity of the air, the greater the velocity, the shorter the time the air spends in the section of the fresh air duct 13 near the air outlet 132; conversely, the lower the velocity, the shorter the time the air remains in the final section of the duct. Since ions need a certain amount of time to combine with air molecules to achieve an effective purification effect, by setting the distance D to no less than 10 centimeters, the air in the fresh air duct 13 can have sufficient time to combine with ions as it flows. In this way, even if the air velocity is relatively fast, a certain purification effect can be guaranteed, thus avoiding insufficient purification.

[0039] in addition, Figure 4 The distance between the ion generator 12 and the air outlet 132 shown is the distance from the part of the ion generator 12 closest to the air outlet 132 to the end face of the air outlet 132. In other cases, it can also be the distance from the corresponding point on the ion generator 12 to the end face of the air outlet 132. This point can be one of the centroid, center, mass center, or geometric center of the ion generator 12.

[0040] In some cases, the air outlet 132 is circular or a regular polygon along the axial direction of the air outlet 132.

[0041] This allows the air to be evenly distributed as it passes through the ion generator 12.

[0042] Specifically, in Figures 1 to 3 In this design, the air outlet 132 is circular along its axial direction, which allows the air to be distributed evenly at the outlet to a certain extent, which is beneficial for the binding of ions and air molecules. In addition, when the shape of the air outlet 132 is a regular polygon, such as a square, a regular pentagon, or a regular hexagon, the air is less likely to form local concentrations when passing through it, thus promoting the even distribution of air.

[0043] In addition, in some cases, the shape of the air outlet 132 can be determined through simulation testing.

[0044] In some cases, the ion generator 12 is detachably mounted on the inner wall of the fresh air duct 13.

[0045] This makes future maintenance and replacement easier.

[0046] Specifically, the fresh air handling unit 10 housing includes a fixing member (not shown). The fixing member movably secures the ion generator 12 within the fresh air duct 13, making the ion generator 12 less susceptible to vibration or displacement due to airflow. In the event of a malfunction of the ion generator 12, the fixing member can be movably detached from the ion generator 12, allowing the ion generator 12 to be removed from the fresh air duct 13 for maintenance and replacement. The fixing member can be a flange or screws.

[0047] Please refer to Figure 4 In some cases, the fresh air handling unit 10 may include a filter 15. The filter 15 may be located within the fresh air duct 13 and away from the air outlet 132.

[0048] In this way, large particles and dust in the air can be removed without causing secondary air pollution.

[0049] Specifically, in Figure 4In this configuration, the filter 15 is positioned on the side of the ion generator 12 furthest from the air outlet 132. When air flows within the fresh air duct 13, the air first passes through the filter 15, allowing the filter 15 to perform preliminary filtration, removing large particles and dust from the air. This prevents the ions released by the ion generator 12 from adsorbing onto the surface of large particles and dust in the air, thus avoiding affecting the air purification effect, and also prevents the air purified by the ion generator 12 from being secondary polluted by these objects.

[0050] Please refer to Figure 4 In some cases, the fresh air handling unit 10 may include a heater. The heater may be located within the fresh air duct 13 and away from the air outlet 132.

[0051] In this way, the temperature of the fresh air can be regulated.

[0052] In some cases, ion generator 12 may include a triplet ion generator.

[0053] This helps improve air purification efficiency.

[0054] Specifically, for the triplet ion generator, on a nanomaterial catalytic substrate, electrons are accelerated through the electron avalanche effect and react with water molecules under electrocatalysis to generate triplet ions composed of negative oxygen ions (O2-), aqueous hydroxyl ions (-OH), and active positive ions (H+). These triplet ions can move with the air and interact with air pollutants (such as allergens, bacteria, viruses, formaldehyde, odors, etc.). Among them, negative oxygen ions and aqueous hydroxyl ions have strong oxidizing properties, effectively killing bacteria and viruses and decomposing harmful gases; while active positive ions help remove dust and particulate matter from the air.

[0055] In addition, since the ion generator 12 is located near the air outlet 132, the killed microorganisms and decomposed VOC (Volatile Organic Compounds) fragments will be directly carried into the room by the airflow and diluted or settled by the environment. They will not accumulate inside the fresh air handling unit 10 and pollute other structures inside the fresh air handling unit 10 (such as filter 15 and fan 11).

[0056] The present invention provides a fan 11 system that may include a fresh air handling unit 10.

[0057] The aforementioned fan 11 system, by placing the ion generator 12 in the fresh air duct 13 near the air outlet 132, allows the newly introduced outdoor air to immediately come into full contact with and mix with ions after passing through the fresh air handling unit 10, so that the ions reach the highest concentration the moment they enter the room, achieving instant purification, and can avoid secondary pollution of the air by pollutants (such as bacterial growth) in the duct.

[0058] Specifically, the fan system 11 can be a fresh air system, an air conditioning system, or a ventilation system. The fan system 11 can include one or more fresh air handling units 10, which can work in conjunction with other fan equipment 11 to regulate the air and ensure the cleanliness of the indoor air.

[0059] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to the embodiments of the present invention without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
