Referring to fig. 5 to 7, in an embodiment, the bottom case 310 has a first cavity 311; the middle partition 600 is installed at the opening of the first cavity 311 to form an air outlet cavity 332 in cooperation with the first cavity 311; the sealing structure includes a first sealing rib 620 configured on the periphery of the inner side surface of the middle partition 600, and a first sealing groove 313 (shown in fig. 8) configured on the periphery of the first cavity 311, wherein the first sealing groove 313 is suitable for the first sealing rib 620 to be inserted and matched.
Specifically, the middle partition 600 is installed at an opening of the first cavity 311 to form the outlet chamber 332 in cooperation with the first cavity 311. Wherein, a first sealing groove 313 is formed around the first cavity 311; the middle partition plate 600 is provided with a vent hole 610 at the center thereof, and the first sealing rib 620 is provided on the periphery of the inner side of the middle partition plate 600. when the middle partition plate 600 is mounted at the opening of the first cavity 311, the first sealing rib 620 of the middle partition plate 600 is inserted into and fitted with the first sealing groove 313 of the first cavity 311, so that the assembly position between the inner circumference of the middle partition plate 600 and the first cavity 311 of the bottom case 310 is sealed, and the air outlet cavity 332 is prevented from leaking air from the circumference of the first cavity 311.
Further, the bottom case 310 is further configured with a second cavity 312 which cooperates with the case cover 320 to form an air inlet cavity 331, and a peripheral wall of the second cavity 312 includes an inner annular wall which is common to the first cavity 311 and the remaining outer annular wall; the sealing structure further includes a second sealing rib 321 configured on the housing cover 320, and a second sealing groove 314 configured on the outer annular wall, wherein the second sealing groove 314 is suitable for the second sealing rib 321 to be inserted.
Specifically, the cover 320 is disposed on the bottom case 310, wherein a portion of the cover 320 covers the second cavity 312 of the bottom case 310 and cooperates with the second cavity 312 to form an air inlet cavity 331; another part of the casing cover 320 covers the middle partition 600 and forms an air passing chamber 333 spaced apart from the middle partition 600.

Wherein the first cavity 311 and the second cavity 312 of the bottom case 310 are adjacent; the peripheral wall of the second cavity 312 is formed by connecting and surrounding an inner annular wall and an outer annular wall. Since the inner annular wall of the second cavity 312 is shared with the first cavity 311, that is, the inner annular wall of the second cavity 312 also forms a part of the circumferential wall of the first cavity 311, as mentioned above, the first sealing groove 313 is formed around the first cavity 311, that is, the first sealing groove 313 is formed on the inner annular wall of the second cavity 312, so as to prevent the airflow of the air outlet cavity 332 from flowing back to the air inlet cavity 331, so that only the second sealing groove 314 is formed on the outer annular wall of the second cavity 312, the circumferential edge of the second cavity 312 can be sealed, and further, the air inlet cavity 331 is prevented from leaking air outwards.
Referring to fig. 5, 6 and 8, in an embodiment, since another portion of the housing cover 320 covers the middle partition 600 and is spaced from the middle partition 600 to form the air passing cavity 333, in order to prevent the air passing cavity 333 from leaking outwards, the sealing structure may further include a third sealing groove 630 formed on the outer side periphery of the middle partition 600; the second sealing rib 321 of the housing cover 320 is extended along the circumference of the housing cover 320 such that a portion of the second sealing rib 321 is inserted into the second sealing groove 314 and another portion is inserted into the third sealing groove 630.
Specifically, the third seal groove 630 and the second seal groove 314 are located at positions corresponding to the circumferential edge of the casing cover 320. The second sealing rib 321 of the case cover 320 extends along the circumference of the case cover 320, so that a part of the second sealing rib 321 is inserted into the second sealing groove 314 of the second cavity 312, so as to seal the air inlet cavity 331 formed between the case cover 320 and the first cavity 311; another portion of the second sealing rib 321 is inserted corresponding to the third sealing groove 630 of the middle partition 600 to seal the air passing chamber 333 formed between the case cover 320 and the middle partition 600. Therefore, the fresh air module 200 of the invention seals the matching position between the middle partition plate 600 and the bottom shell 310, the matching position between the middle partition plate 600 and the shell cover 320, and the matching position between the bottom shell 310 and the shell cover 320, thereby greatly improving the sealing effect of the fresh air module 200 and effectively preventing air leakage.
Considering that the air passing cavity 333 is formed between the middle partition 600 and the case cover 320 at an interval, the air passing cavity 333 communicates with the air inlet cavity 331 of the vent hole 610 of the middle partition 600, and the third sealing rib 631 is formed inside the third sealing groove 630, the air flow flowing from the air inlet cavity 331 to the air outlet cavity 332 may be blocked by the third sealing rib 631 and may not enter the air passing cavity 333 easily. To solve the problem, the third sealing rib 631 is provided with an air passing notch 632 at a position where the air passing cavity 333 is butted with the first cavity 311, so that the air flow of the air inlet cavity 331 can enter the air passing cavity 333 from the air passing notch 632, and the third sealing groove 630 is prevented from blocking the air flow.
Referring to fig. 4, 5 and 7, based on any of the above embodiments, the fresh air module 200 further includes a purification assembly 500, and the purification assembly 500 is installed on the middle partition 600 in a drawable manner and covers the air inlet side of the ventilation hole 610. That is, the air purifying assembly 500 is located in the air passing cavity 333, and the air passing cavity 333 has a larger space and a wider cross section than the air inlet cavity 331, so that the air purifying assembly 500 can be designed to be larger, and the air purifying assembly 500 can capture more air pollutants.
Specifically, the housing 300 has a mounting opening disposed on one side of the fresh air outlet 302, and the mounting opening is disposed in a strip shape and extends in the same direction as one side of the fresh air outlet 302. The purification assembly 500 is installed on the middle partition 600 to be drawable from the installation opening. The user can draw the purification assembly 500 out of the mounting port for cleaning or replacement; the cleaning assembly 500 can be pushed into the air inlet side of the air vent 610 of the middle partition 600 from the mounting opening to clean the air flowing from the air inlet chamber 331 to the air outlet chamber 332 through the air vent 610, so as to remove the pollutants in the air.
As to the structure of the purification assembly 500, there may be various designs without limitation. Such as but not limited to: the purification assembly 500 includes a mounting frame 510 and a purification member 520 mounted on the mounting frame 510. The purifying member 520 may be adapted to remove any one or more of dust, fine particles, microorganisms, organic volatile gas (such as formaldehyde, etc.), and other air pollutants from the air. The specific type of the purifying member 520 can be selected according to the function thereof, and the purifying member 520 can be any one or combination of a common filter screen, a HEPA (high efficiency particulate air) screen, a formaldehyde remover and an IFD (internal-flow filtration) filter; and the filter screen can also be any one or combination of a plurality of primary filter screens, intermediate filter screens and high-efficiency filter screens.
In addition, since the air inlet end of the fan assembly 400 corresponds to the air vent 610, it is equivalent that the purification assembly 500 corresponds to the air inlet end of the fan assembly 400. The air flow in the air inlet cavity 331 is firstly purified into relatively clean fresh air by the purification assembly 500, and then the clean fresh air enters the air inlet end of the fan assembly 400 through the air vent 610 and is finally blown out by the fan assembly 400 along the radial direction thereof. Compared with the air inlet cavity 331, the air passing cavity 333 between the middle partition plate 600 and the case cover 320 has a larger space, so that the purifying surface for allowing air of the purifying assembly 500 to pass through for purification can be designed to be larger according to the size of the vent 610, and the efficiency of the purifying assembly 500 for purifying air is improved. Since the purge assembly 500 is designed to be relatively large, the amount of air that can be purged by the purge assembly 500 is increased, and thus the life of the purge assembly 500 can be extended, and the period for replacing the purge assembly 500 can be extended.
Since the mounting opening is close to the fresh air outlet 302, that is, a part of the periphery of the middle partition plate 600 is located between the mounting opening and the fresh air outlet 302, there may be a gap between the middle partition plate 600 and the fresh air outlet 302, which is easy to allow the air flow coming out of the air cavity 332 to leak from the gap without passing through the fresh air outlet 302. To reduce the occurrence of such problems, optionally, a sealing material piece is configured at the periphery of the fresh air outlet 302 to seal the gap around the fresh air outlet 302 and to seal the gap around the fresh air outlet 302. The sealing material may be a rubber or silicone material.
Referring to fig. 4, 5 and 8, it is considered that if a gap is formed between the purifying assembly 500 and the windward side of the middle partition plate 600, part of the airflow in the air inlet chamber 331 may directly enter the vent hole 610 of the middle partition plate 600 through the gap and then enter the air outlet chamber 332 through the vent hole 610 without passing through the purifying assembly 500 for purification. To avoid this, optionally, the sealing structure further includes a fourth sealing rib 640 formed on the air inlet side of the ventilation hole 610, and the fourth sealing rib 640 surrounds the purification assembly 500 and is attached to the outer peripheral wall of the purification assembly 500. The air flow in the air inlet cavity 331 is blocked by the fourth sealing rib 640, cannot pass through the gap between the purification assembly 500 and the middle partition plate 600, and can only wind around the air inlet surface of the purification assembly 500, and then passes through the purification assembly 500 and enters the air vent 610 of the middle partition plate 600, so that the fresh air flow can be sufficiently filtered and purified.
For convenience the purification subassembly 500 can be installed on median septum 600 with the pull, is the setting of half race way shape with fourth sealed muscle 640, the both ends orientation of fourth sealed muscle 640 the installing port extends to the inboard formation at fourth sealed muscle 640 supplies the mounting groove of purification subassembly 500 installation. When the purification component 500 is installed, the purification component 500 is pushed into the installation groove from the installation opening inwards until the annular peripheral wall of the purification component 500 is in fit and close contact with the inner groove wall of the installation groove, and the installation of the purification component 500 is completed; at this time, the purification assembly 500 covers the ventilation hole 610 of the middle partition 600.
Referring to fig. 4 to 6, based on any embodiment, the fresh air module 200 further includes a fan assembly 400, the fan assembly 400 is installed in the first cavity 311 of the bottom case 310, the fan assembly 400 includes a centrifugal wind wheel 410 and a motor 420, one end of the centrifugal wind wheel 410 is connected to the motor 420, and the other end of the centrifugal wind wheel 410 forms an air inlet end and corresponds to the air vent 610 of the middle partition 600. In the working process of the fresh air module 200, the air flow in the air inlet cavity 331 directly enters the centrifugal wind wheel 410 from the air inlet end of the centrifugal wind wheel 410 after passing through the air vent 610 of the middle partition plate 600, and then is thrown out by the centrifugal wind wheel 410 at a high speed, so that the air supply efficiency of the centrifugal wind wheel 410 is enhanced.
In addition, since the motor 420 of the blower fan assembly 400 is mounted at the bottom of the first cavity 311 of the bottom chassis 310 to be away from the ventilation hole 610 of the middle partition 600, wind shielding is avoided. In addition, the motor 420 and the centrifugal wind wheel 410 can be installed in the first cavity 311 from the same side of the bottom shell 310, and if the centrifugal wind wheel and the motor are fixed by screwing on the same side, the assembling direction does not need to be adjusted repeatedly, and the assembling efficiency is improved.
