[0002] With the widespread application of fresh air systems in both civil and industrial sectors, the connection structure between the fresh air unit's air inlet and the ductwork directly affects installation efficiency and system sealing. Currently, fresh air unit air inlets commonly use a connection method involving a mounting plate and a mounting sleeve, secured circumferentially with multiple screws to fix the ductwork. Specifically, during installation, the mounting sleeve must be inserted into the pre-drilled holes in the mounting plate, and the operator must manually press the mounting sleeve to maintain its relative position with the mounting plate, while simultaneously tightening each screw to complete the fixation. This method has significant drawbacks: firstly, continuous external force must be applied during installation to prevent the mounting sleeve from shifting, which is particularly difficult and poses safety hazards, especially when working alone or at heights; secondly, manually pressing the mounting sleeve and tightening the screws is cumbersome, time-consuming, and labor-intensive, resulting in low installation efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The following is combined with Figures 1 to 8 This invention describes a fresh air outlet structure component and a fresh air unit provided in an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0033] An embodiment of the first aspect of this utility model provides a fresh air outlet structure component, such as... Figures 1 to 8 As shown, it includes: a mounting plate 100, which is connected to an indoor air vent, and a pre-positioning groove 200 is provided on the mounting plate 100; a mounting cylinder 300, on which a pre-positioning block 400 is provided, the pre-positioning block 400 is adapted to the pre-positioning groove 200, and the pre-positioning block 400 can be rotatably inserted into the pre-positioning groove 200; and a connector 500, which connects the mounting plate 100 and the mounting cylinder 300.

[0034] The fresh air outlet structure assembly provided by this utility model includes a mounting plate 100, a mounting cylinder 300, and a connector 500. The mounting plate 100 is connected to an indoor air vent, and a pre-positioning groove 200 is provided on the mounting plate 100. A pre-positioning block 400 is provided on the mounting cylinder 300, and the pre-positioning block 400 is adapted to the pre-positioning groove 200 and can be rotatably inserted into the pre-positioning groove 200. The connector 500 connects the mounting plate 100 and the mounting cylinder 300.

[0035] During use, align the mounting cylinder 300 with the corresponding installation position on the mounting plate 100, rotate the mounting cylinder 300, causing it to rotate and limit the positioning block 400 into the positioning groove 200. Then, release the mounting cylinder 300 and connect the connector 500 between the mounting cylinder 300 and the mounting plate 100. With this structure, workers can first pre-position the mounting cylinder 300 and the mounting plate 100 using the positioning block 400 and the positioning groove 200, then release the mounting cylinder 300 and install the connector 500. This eliminates the need for manual pressure on the mounting cylinder 300, reducing operational difficulty and eliminating safety hazards associated with working at heights; it also saves time and effort during installation, improving efficiency.

[0036] In one embodiment of the present invention, the mounting plate 100 includes: a plate body; a mounting hole, the mounting hole being disposed on the plate body and adapted to the mounting cylinder 300, and a pre-positioning groove 200 being disposed on the back edge of the mounting hole.

[0037] Furthermore, in one embodiment of the present invention, the prepositioning block 400 is disposed at the inner end edge of the mounting cylinder 300, the mounting cylinder 300 is connected to the mounting hole and the prepositioning block 400 is able to pass through the mounting hole and be rotated and limited into the prepositioning groove 200.

[0038] For example, an L-shaped structure is provided on the back edge of the mounting hole on the plate, forming a pre-positioning groove 200 between the L-shaped structure and the back of the plate. The pre-positioning groove 200 is adapted to the pre-positioning block 400. Figure 3 and Figure 4 As shown, during installation, the mounting cylinder 300 is aligned with the mounting hole, allowing the pre-positioning block 400 on the mounting cylinder 300 to extend beyond the mounting hole into the back side of the plate. Rotating the mounting cylinder 300 rotates the pre-positioning block 400 into the pre-positioning groove 200. This completes the pre-positioning operation between the mounting cylinder 300 and the mounting plate 100. Subsequently, the mounting cylinder 300 is released, and the connector 500 can be installed independently.

[0039] In one embodiment of the present invention, a plurality of prepositioning grooves 200 are arranged at intervals along the circumferential direction of the mounting hole; a plurality of prepositioning blocks 400 are correspondingly arranged on the inner end edge of the mounting cylinder 300.

[0040] Furthermore, in one embodiment of this utility model, there are multiple connectors 500, and the connectors 500 and the prepositioning grooves 200 are arranged alternately.

[0041] For example, such as Figures 1 to 4As shown, in this embodiment, four pre-positioning slots 200 are evenly distributed along the circumferential direction of the mounting hole. Correspondingly, four pre-positioning blocks 400 are evenly distributed at the inner edge of the mounting cylinder 300. A connector 500 is provided between each pair of adjacent pre-positioning slots 200 and pre-positioning blocks 400. During installation, rotating the mounting cylinder 300 can drive the four pre-positioning blocks 400 to rotate and be positioned within their respective pre-positioning slots 200. After pre-positioning is completed, the connector 500 is then installed. This structural arrangement improves the tightness of the connection between the mounting plate 100 and the mounting cylinder 300.

[0042] In one embodiment of the present invention, the prepositioning groove 200 is a wedge-shaped groove; the prepositioning block 400 is a wedge-shaped block adapted to the wedge-shaped groove.

[0043] For example, such as Figure 7 and Figure 8 As shown, the pre-positioning groove 200 is a wedge-shaped groove, and the pre-positioning block 400 is a wedge-shaped block, which are compatible with each other. Thus, the outer end of the wedge-shaped positioning groove can press against the root of the wedge-shaped positioning block, thereby improving the connection and sealing between the mounting plate 100 and the mounting cylinder 300.

[0044] In one embodiment of the present invention, the fresh air outlet structure component further includes: an air duct 600, which is inserted and connected to the inner side of the mounting cylinder 300.

[0045] In one embodiment of this utility model, the duct 600 is a corrugated pipe; the fresh air outlet structure component further includes a buckle 700, which is disposed on the side wall of the mounting cylinder 300 and can be fixedly snapped onto the outside of the corrugated pipe.

[0046] For example, such as Figure 5 As shown, two clips 700 are symmetrically arranged on the side wall of the mounting cylinder 300. When the duct 600 is inserted into the inside of the mounting cylinder 300, the duct 600 can fit against the inner side wall of the mounting cylinder 300, and the clips 700 can be locked in a certain corrugated section on the outer side of the corrugated pipe.

[0047] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the fresh air outlet structure component also includes: a limiting ring rib 800, which is disposed on the inner side wall of the mounting cylinder 300 and is fitted to the inner end face of the air duct 600.

[0048] Compared with the existing structure in which the duct 600 is sleeved on the outside of the mounting cylinder 300, this fresh air outlet structure assembly inserts the duct 600 into the inside of the mounting cylinder 300, and sets a limiting ring rib 800 inside the mounting cylinder 300, so that after the duct 600 is installed in place, the limiting ring rib 800 can completely fit with the inner end face of the duct 600, which can greatly improve the connection and sealing between the duct 600 and the mounting cylinder 300.

[0049] A second aspect of this utility model provides a fresh air ventilator, including the fresh air indoor duct structure described above.

[0050] Furthermore, the fresh air ventilator provided by this utility model, since it includes the fresh air outlet structure component as described above, also possesses the advantages described above.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
