Fig. 5 is a partially enlarged schematic view of a cross section in the width direction in a plan view of a mask of an air exchange device according to an embodiment of the present invention. In the embodiment of the present invention, since the face mask 120 is a plate-shaped structure, it can have a design of length, width, and height (i.e. plate thickness), wherein the length direction is the opposite direction of the front wall 403 and the rear wall 404 of the ventilation opening (the direction of the air inlet 501 close to the air outlet 502 or the opposite direction); the width direction and the length direction are perpendicular to the same plane, and are opposite to the vent left wall 401 and the vent right wall 402; the height direction is the direction of the plate thickness and is perpendicular to the plane of the length direction and the width direction.

The air guide part 122 is disposed at the vent 121, and has a plurality of plate-shaped structures with a substantially rectangular shape, the air guide part 122 extends from one end 701 of the air guide part of the vent 121 to the other end 702 of the air guide part, and the plurality of plate-shaped structures are arranged at intervals to form a gap through which air passes, so as to guide the air.

The air guide portion one end 701 is an end of the air guide portion 122 located in the width direction, that is, an end close to the vent left wall 401. The other end 702 of the air guide portion is opposite to the one end 701 of the air guide portion, i.e., is close to the vent right wall 402.

The outlet air guide part 602 is disposed at the outlet 502, and guides the air inside the enclosure 110 to the outside of the enclosure 110.

The following description refers to fig. 6 to 7. Fig. 6 is a partially enlarged schematic view of a cross section in a longitudinal direction in another plan view of the mask of the ventilation apparatus according to the embodiment of the present invention. Fig. 7 is a partially enlarged schematic view of the structure of the cross section in the longitudinal direction in another perspective view of the mask of the ventilation device according to the embodiment of the present invention.

The dust collecting plate 603 is inclined with respect to the plane of the air vent 121, and is a plate-like member extending in the longitudinal direction of the air guide portion 122.

As shown in fig. 8, the rib 605 is a plate-like member connecting the adjacent dust collecting plates 603, intersects the dust collecting plates 603, and has both ends connected to the vent wall 202. The end of the rib 605 on the side of the reverse casing 110 is positioned on the casing 110 side with respect to the end of the dust collecting plate 603 on the side of the reverse casing 110. The end portion of the rib 605 on the side opposite to the casing 110 means an end portion of the rib 605 on the side away from the casing 110 in the mounted state, i.e., a rib lower end portion 801, with the rib 605 as a boundary; the end of the dust plate 603 on the side of the reverse housing 110 is defined by the dust plate 603, and in the attached state, the end of the dust plate 603 on the side away from the housing 110, that is, the lower end 802 of the dust plate. In other words, in the attached state, the lower end 801 of the rib (the end of the rib 605 on the side away from the casing 110) is closer to the casing 110 than the lower end 802 of the dust board (the end of the dust board 603 on the side away from the casing 110).

The reinforcing ribs 605 include an air inlet reinforcing rib 410 disposed at the air inlet 501, and an air outlet reinforcing rib (not shown) disposed at the air outlet 502. The upstream end of the intake stiffener 410 is located further downstream than the upstream end of the intake dust panel 310. The downstream end of the air outlet reinforcing rib is located on the upstream side than the downstream end of the air outlet dust laying plate 320.

When the ventilator 100 is in the mounted state, the cover 120 covers the opening 111 of the casing 110, and covers the ventilation unit 130 and the air treatment unit 140 provided inside the casing 110. A circulation air duct is formed in the ventilation device 100, and the circulation air duct is used for blowing air out of the basket body 110 again after the air passes through an air inlet 501 on the face guard 120, the filter part 142 of the air processing unit 130, the snail shell air inlet 301, the fan blades 132, the snail shell air outlet 302, the heating part 141 of the air processing unit 140 and the air outlet 502 on the face guard 120 in sequence; the ventilation device 100 further includes a ventilation air duct for blowing the air out of the housing 110 again after passing through the air inlet 501 of the mask 120, the filter portion 142 of the air handling unit 140, the snail shell air inlet 301, the fan blades 132, the snail shell air outlet 302, and the ventilation air outlet 114 of the housing 110 in this order.

The following describes an embodiment of the ventilation apparatus disclosed in the present invention.

When the ventilator 100 is in the installed state, the air outside the housing 110 is sucked into the housing 110 through the air inlet 501 of the mask 120 by the suction of the fan 132, filtered into clean air by the filter unit 142 of the air treatment unit 140, and then enters the snail shell 131 through the snail shell air inlet 301. When the air-path switching plate connects the snail shell outlet 302 with the outlet 502 of the face mask 120, the air blown out from the snail shell outlet 302 is heated by the heater 141 under the guidance of the air-path switching plate, and then is blown out of the housing 110 through the outlet 502 of the face mask 120, thereby providing warm and clean air.

When the air duct switch board connects the snail shell outlet 302 with the ventilation outlet on the basket 110, the air blown out from the snail shell outlet 302 is guided by the air duct switch board and blown out of the basket 110 through the ventilation outlet 114 on the basket 110.

The following description will take the air inlet guide portion 601 as an example.

Since the air inlet 501 is provided with the air inlet guiding portion 601, air will impact on the air inlet guiding portion 601 when being sucked by the fan blades 132 and blown to the air inlet guiding portion 601. At this time, a part of dust and the like contained in the air adheres to the surface of the air inlet guide portion 601. In order to prevent dust accumulation and reduce the air inlet area of the air inlet 501 to affect the air inlet volume, a user needs to wipe the surface of the air inlet guiding portion 601 with a cleaning tool such as a rag to remove dust attached to the air inlet guiding portion 601.

When a user wipes the cleaning cloth from one end of the air inlet guiding portion 601 to the other end thereof, dust may be attached to the cleaning cloth by friction and move to the other end of the air inlet guiding portion 601. Because a certain distance is formed between at least one end of the air inlet air guiding portion 601 and the vent wall 202, when dust moves to the end of the air inlet air guiding portion 601 along with wiping of a user, the dust is pushed out of the air inlet air guiding portion 601, and falls down from a gap formed between the air inlet air guiding portion 601 and the vent wall 202 or is attached to a cleaning cloth under the action of gravity. Therefore, the air inlet air guiding part 601 is convenient to clean.

Meanwhile, when the ventilator 100 is operated, the air is sucked by the fan blades 132 and passes through the gaps between the plurality of plate-shaped air guiding portions, and dust in the air may be attached to the side surfaces of the air guiding portions 122. When dust adheres to the side surface of the air guide portion 122, since the gap is small, the user must use a slim tool for cleaning, and thus, cleaning of the air guide portion 122 is inconvenient.

Therefore, in the present invention, the air inlet air guiding portion 601 includes the air inlet dust-collecting plate 310, and the air inlet dust-collecting plate 310 is inclined to the plane where the ventilation opening 121 is located, and the air inlet dust-collecting plate 310 has the windward side 210 facing the upstream side.

When the air is guided by the air inlet dust-collecting plate 310 and impacts the air inlet air-guiding portion 601, the area of the air contacting the air inlet air-guiding portion 601 increases, and when the air impacts the air inlet dust-collecting plate 310, more air impacts the windward surface 210 of the air inlet dust-collecting plate 310.

Meanwhile, the air inlet dust collecting plate 310 is arranged obliquely, so that the air speed of the air entering the air inlet 501 is increased. At this time, the air will impinge on the windward side 210 of the intake dust panel 310 at a higher velocity. Dust contained in the air will be firmly attached to the windward side 210 with the impact and will not easily pass through the vent 121 with the air. Thus, more dust will adhere to and accumulate on the windward side 210 of the intake dust collecting plate 310, thereby inhibiting dust from adhering to the leeward side 220 of the intake dust collecting plate 310.

Since the windward surface 210 of the air inlet dust-collecting plate 310 is inclined toward the outer side of the casing 110 in the mounted state, that is, inclined downward, when the air inlet air guiding portion 601 is cleaned by a user, the windward surface 201 of the air inlet dust-collecting plate 310 can be conveniently wiped, and the air guiding portion 122 can be more conveniently cleaned.

In addition, since the dust-proof plate 604 extends from the upstream end of the air inlet dust-collecting plate 310 and parallel to the plane of the air vent 121, the included angle α formed between the dust-proof plate 604 and the air inlet dust-collecting plate 310 is greater than 90 degrees. It can be ensured that the windward surface 210 of the inlet dust panel 310 faces downward, i.e. the upstream side of the inlet 501, and the dust-proof plate 604 does not block the windward surface 210 of the inlet dust panel 310. When the air hits the air guiding portion 122, the air can have more contact area with the air inlet dust-collecting plate 310 and the dust-proof plate 604. Accordingly, a part of the dust contained in the air adheres to the dust-proof plate 604, and thus the dust is prevented from entering the enclosure 110, and the contamination of other components in the enclosure 110 is suppressed. Meanwhile, a larger part of the dust contained in the air will be attached to the windward side 210 of the air inlet dust collecting plate 310, so that the cleaning is more convenient.

Since the dust collecting plate 603 is a plate-like member arranged at intervals on the air guide portion 122, when an air flow having a high wind speed impinges on the dust collecting plate 603, the dust collecting plate 603 may be deformed toward the downstream side of the air flow. Therefore, the air guide part 122 is provided with a rib 605 for connecting the adjacent dust collecting plates 603. Since the reinforcing rib 605 intersects with the dust board 603 and connects the adjacent dust boards 603, the force of the air striking the dust board 603 can be dispersed, thereby suppressing the deformation of the dust board 603.

Further, when the user wipes the dust board 603 from one end to the other end of the windward side 210, the dust may be accumulated at a position where the rib 605 abuts the windward side 210 of the dust board 603 due to interference of the portion where the rib 605 protrudes from the windward side 210 of the dust board 603. Therefore, the end of the rib 605 on the side of the counter casing 110 is provided closer to the casing 110 than the end of the dust collecting plate 603 on the side of the counter casing 110, and the height of the rib 605 protruding beyond the windward surface 210 of the dust collecting plate 603 is reduced. Therefore, when a user wipes the dust collecting plate 603 from one end to the other end of the windward side 210, interference with the portion of the rib 605 protruding from the windward side 210 of the dust collecting plate 603 is reduced, accumulation of dust at the joint of the rib 605 and the windward side 210 of the dust collecting plate 603 is suppressed, and cleaning of the air guide portion 122 is facilitated.

The above embodiment is described with reference to the air inlet guiding portion 601, and similarly, the air outlet guiding portion 602 also has the same effect of being convenient for cleaning.

Unlike the present embodiment, in other embodiments, the ventilation device 100 may not include the air processing unit 140, or the air processing unit 140 may be a component for performing other processing on the air, such as a humidification unit or a dehumidification unit. Alternatively, the ventilation device 100 may not include the air path switching plate. Furthermore, the ventilation device may have only one air outlet 502.

Therefore, the utility model provides a breather convenient to it is clean.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
