[0031] Reference below Figure 1-Figure 2 The ventilation, air supply and purification unit according to the embodiment of the utility model is described.

[0032] like Figure 1-Figure 2 As shown, the ventilation and air supply purification unit includes a unit housing 100, a diamond-shaped filter assembly 200, an air supply mechanism 110 and an exhaust mechanism 120. Specifically, an air supply chamber 101 and an exhaust chamber 102 are provided in the unit housing 100, and the ends of the air supply chamber 101 and the exhaust chamber 102 meet in the middle of the unit housing 100. The internal space of the unit housing 100 is used as a cavity, and the air supply chamber 101 and the exhaust chamber 102 are connected to each other, simplifying the internal space structure of the air supply unit.

[0033] The diamond filter assembly 200 is arranged at the intersection of the air supply chamber 101 and the exhaust chamber 102, and is used to separate the air supply chamber 101 and the exhaust chamber 102. When the diamond filter assembly 200 is not installed in the unit housing 100, the air supply chamber 101 and the exhaust chamber 102 seem to be connected. When the diamond filter assembly 200 is inserted into the unit housing 100 and installed in place, the air supply chamber 101 and the exhaust chamber 102 are separated from each other. The air supply mechanism 110 is arranged at the end of the air supply chamber 101, that is, at the air outlet of the air supply chamber 101, and the exhaust mechanism 120 is arranged at the end of the exhaust chamber 102, that is, at the air outlet of the exhaust chamber 102.

[0034] Among them, the diamond filter assembly 200 includes four groups of one-way filter nets, the filtering directions of the two one-way filter nets arranged opposite to each other are the same, and the filtering directions of the two adjacent one-way filter nets are opposite. The diamond filter assembly 200 divides the two chambers into four chambers, the two chambers of the air supply chamber 101 are connected through the one-way filter nets arranged opposite to each other, and the two chambers of the exhaust chamber 102 are connected through the one-way filter nets arranged opposite to each other. All air flows must pass through the diamond filter assembly 200, so that the dust in the unit housing 100 is concentrated in the diamond filter assembly 200, which is convenient for the staff to clean the filter net inside the unit housing 100. The staff only needs to extract the diamond filter assembly 200 to be able to extract all the filter nets in the unit housing 100 at one time.

[0035] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the diamond filter assembly 200 is detachably connected to the unit housing 100 and extends from the side wall of the unit housing 100 into the unit housing 100. Specifically, the diamond filter assembly 200 is inserted into the unit housing 100 from the side wall of the unit housing 100. A maintenance cover can be provided at the position of the side wall of the unit housing 100 corresponding to the diamond filter assembly 200, and the staff can remove the diamond filter assembly 200 after opening the maintenance cover. The maintenance cover is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0036] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the one-way filter includes an air supply filter 210 and an exhaust filter 220. The one-way filter connected to the air supply chamber 101 is the air supply filter 210, and the one-way filter connected to the exhaust chamber 102 is the exhaust filter 220. Specifically, the air supply filter 210 and the exhaust filter 220 have the same structure, but are installed in different directions. The filtering direction of the air supply filter 210 is set toward the side of the air supply mechanism 110, and the filtering direction of the exhaust filter 220 is set toward the side of the exhaust mechanism 120, so that the air flow in the two chambers forms a one-way flow. And all the air passing through the diamond filter assembly 200 can be filtered and purified. After the air at the air inlet of the exhaust chamber 102 enters the one-way filter, it can also enter the air supply chamber 101 from the air supply filter 210 of the air supply chamber 101, which helps to increase the air supply flow of the air supply chamber 101.

[0037] In some embodiments of the present invention, the diamond filter assembly 200 includes a filter frame (not shown in the drawings), which is used to install a one-way filter. Specifically, four sets of one-way filters are installed on the filter frame, and then the filter frame is inserted into the unit housing 100.

[0038] In some embodiments of the present invention, a flow sensor (not shown in the drawings) is provided inside the diamond filter assembly 200, and the flow sensor is used to monitor the use status of the diamond filter assembly 200. Specifically, when the flow sensor inside the diamond filter assembly 200 detects that the flow rate is lower than a specified threshold, a feedback signal is fed back, and at this time, too much dust is accumulated in the one-way filter screen of the diamond filter assembly 200, and the staff needs to disassemble and inspect it for maintenance.

[0039] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a heat exchanger 130 is provided in the air supply chamber 101, and the heat exchanger 130 is used to adjust the air supply temperature of the air supply chamber 101. Specifically, the structure of the heat exchanger 130 is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment.

[0040] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air supply mechanism 110 and the air exhaust mechanism 120 adopt a turbofan structure. Specifically, the turbofan structure can form a high-speed airflow in the corresponding chamber and increase the air delivery flow rate.

[0041] In some embodiments of the present invention, the air outlet of the air supply mechanism 110 is connected to the air supply duct, and the air inlet of the exhaust chamber 102 is connected to the exhaust duct. The air outlet of the air supply mechanism 110 extends to the inside of each space through the air supply duct, and the air inlet of the exhaust chamber 102 extends to each space through the exhaust duct. Each space is connected to the air supply mechanism 110 and the exhaust mechanism 120 to achieve ventilation and purification in the space.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air supply mechanism 110 and the exhaust mechanism 120 are arranged on the same side of the unit housing 100. Specifically, when the air supply mechanism 110 and the exhaust mechanism 120 need to be repaired and maintained, the staff disassembles the side wall of the unit housing 100, and can repair and maintain the air supply mechanism 110, the exhaust mechanism 120 and the diamond filter assembly 200 at the same time, which is convenient for the staff to maintain.

[0043] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
