As shown in fig. 1-8, the present disclosure provides a fresh air module including a housing 1, a filter screen 2, and a fan 3. Wherein the sieve 2 divides the housing 1 into a first chamber 114 and a second chamber 115. The blower 3 is disposed within the second chamber 115. Alternatively, the filter screen 2 may be a high efficiency air filter screen (HEPA filter screen) or other form of filter screen. The housing 1 is provided with an air inlet 1111 communicating with the first chamber 114 and an air outlet 1121 communicating with the second chamber 115. A deflector 1112 is disposed in the first chamber 114, the deflector 1112 being configured to enable at least part of the fresh air entering the housing 1 to flow along the outer circumferential surface of the deflector 1112 in the direction of the screen 2.

Specifically, after the fan 3 is started, negative pressure is generated to enable external fresh air to enter the casing 1, the fresh air enters the first chamber 114 through the air inlet 1111 and moves towards the filter screen 2 along the outer circumferential surface of the guide column 1112 under the guidance of the guide column 1112, and the fresh air enters the second chamber 115 after being filtered by the filter screen 2 and then enters the room through the air outlet 1121 under the action of the fan 3.

Referring to fig. 1 and 4, the flow process of the fresh air guided by the guide column 1112 may be disassembled into two parts, specifically, after the fresh air enters the housing 1, the fresh air flows along the outer circumferential surface of the guide column 1112 under the guidance of the guide column 1112, and then flows along the extending direction of the guide column 1112 (i.e. the direction towards the filter screen 2). It should be understood that this flow of fresh air does not occur sequentially in time, but rather is concurrent, and that disassembly is merely for ease of understanding.

The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects: the new trend module that this disclosure provided makes the new trend can flow along the outer peripheral face of guide post 1112 towards the direction of filter screen 2 under the guide of guide post 1112, namely, through set up guide post 1112 in first cavity 114, guide new trend carries out orderly flow, has reduced the impact that the vortex of new trend formed to casing 1 to more smoothly flow into fan 3 after filter screen filtration 2, realized not reducing the purpose of noise of new trend module when fresh air volume.

For further explanation, referring to fig. 5 and 6, fig. 6 shows a conventional fresh air module without the flow guide pillars 1112, it is possible to clearly observe the air flow lines forming the turbulent eddies, and these air flow lines spiral inside the first chamber 114 to form impacts on the housing 1, which generate noise and reduce fresh air volume due to wind loss. In the fresh air module provided by the present disclosure shown in fig. 5, by providing the flow guide columns 1112, the flow guide columns 1112 form a constraint on the air flow lines, so that at least part of the air flow lines are forced to flow along the outer circumferential surface of the flow guide columns 1112 towards the direction of the filter screen 2, which can be obtained by comparing the distribution and mess degree of the air flow lines in fig. 5 and 6, and by reducing the impact of the fresh air on the casing 1, on one hand, the noise can be reduced, and on the other hand, the air loss can be reduced.

The guide column 1112 may be configured with an axis parallel or coaxial with the rotational axis of the blower 3. In some embodiments, the guide column 1112 may be configured as a cylinder or an elliptical cylinder with an axis parallel or coaxial with the rotational axis oo' of the blower 3, wherein fig. 4 shows the guide column 1112 configured as an elliptical cylinder and fig. 8 shows the guide column 1112 configured as a cylinder. The axis of the flow guiding column 1112 is parallel or coaxial with the rotation axis oo' of the fan 3, which is beneficial to further guiding the flow direction of the fresh air so as to avoid impact on the shell 1. In addition, the cylindrical or elliptic cylindrical flow guide column 1112 has a smooth outer circumferential surface, which is beneficial to guiding the fresh air to flow along the outer circumferential surface of the flow guide column 1112, and avoiding unnecessary noise caused by the impact between the fresh air and the flow guide column 1112. Alternatively, the length range of the guide post 1112 in the extending direction may be set in a range of 10 mm to 50 mm according to actual needs. For elliptic cylinders and the like, the axis is the axis where the geometric center is located. In other embodiments, the axis of the flow guiding column 1112 is parallel or coaxial with the rotation axis of the fan 3, and a gap is formed between the end of the flow guiding column 1112 and the filter screen 2, and the gap is beneficial to collecting fresh air and avoiding interference between the flow guiding column 1112 and the filter screen 2.

As shown in fig. 4, the guide column 1112 includes a first end connected to the housing 1 and a second end extending in the direction of the screen 2, and the radial dimension of the guide column 1112 tapers from the first end to the second end. The guide column 1112 can be integrally formed with the housing 1, for example, by injection molding, which is beneficial to improving the connection strength between the guide column 1112 and the housing 1. The size of the flow guiding column 1112 gradually decreases from the first end to the second end, i.e. gradually narrows from the first end to the second end, so that the direction of the fresh air flowing along the outer circumferential surface of the flow guiding column 1112 to the filter screen 2 is more beneficial.

Further, the outer circumferential surface of the flow guiding column 1112 transitions from the first end to the second end in a straight line or in a curve. For example, fig. 3 shows a configuration in which the first end of the flow post 1112 transitions straight toward the second end. The straight transition configuration facilitates a smoother flow of fresh air into the fan 3, while the curved transition, such as an arcuate transition, facilitates a less aggressive flow of fresh air to the flow post 1112.

Referring to fig. 1, 4, 7 and 8, the housing 1 includes a housing body 11 and an air inlet channel 12, an air inlet 1111 is disposed on the housing body 11, one end of the air inlet channel 12 is communicated with the air inlet 1111, and the other end of the air inlet channel 12 is provided with an interface 121 for connecting with a fresh air pipe, wherein an axis AA 'of the interface 121 is perpendicular to an axis BB' of the air inlet 1111 or is disposed at an angle α. Thus, as shown by the arrow in the drawing, the fresh air needs to pass through the air inlet channel 12 and then enter the shell body 11.

That is, unlike the related art, which makes the fresh air directly enter the case 1, the present disclosure makes the fresh air first enter the air intake channel 12, avoiding the high-speed fresh air from directly impacting the inner wall of the case body 11, thereby reducing the wind loss and being beneficial to improving the fresh air volume, and simultaneously considering that the axis of the interface 121 is perpendicular to the axis of the air intake 1111 or is set at an angle α, the pressure difference of the fresh air is greatly reduced when the fresh air enters the case body 11 after passing through the air intake channel 12, thereby generating little or no acceleration to the fresh air, being beneficial to further avoiding the impact of the fresh air on the inner wall of the case body 11, and further reducing the noise.

For further explanation, continuing to refer to the velocity cloud of fig. 7, where the velocity of the fresh air is observed to be significantly more uniform and lower at the location of the elbow entering the housing body 11 from the air intake channel 12, i.e., the large black area of the elbow in the illustration.

In some embodiments, as shown in fig. 2 and 3, the housing 1 may be configured as a split design, thereby facilitating assembly of the components therein. Specifically, the casing 1 includes a first casing 111, a second casing 112, and a middle frame 113, the first casing 111 and the second casing 112 are detachably fastened to the middle frame 113 from two sides to enclose a first chamber 114 and a second chamber 115, the filter screen 2 is disposed on a side of the middle frame 113 facing the first casing 111, and the fan 3 is disposed on a side of the middle frame 113 facing the second casing 112. For example, the first housing 111 is configured as a box structure, and the second housing 112 is configured as a volute structure for the mating installation fan 3. Optionally, the guide post 1112 is integrally formed with the first housing 111. A clamping structure 13 is provided between the first housing 111 and the middle frame 113 and/or between the second housing 112 and the middle frame 113 so as to be detachably connected.

According to a second aspect of the embodiments of the present disclosure, a fresh air conditioner is provided, including any one of the fresh air modules described above, and has all the beneficial effects thereof, which are not described herein again.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. This disclosure is intended to cover any adaptations, uses, or adaptations of the disclosure following the general principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
