DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides a fresh air exchange device that can introduce outdoor air after temperature change and purification to improve the indoor air quality, and includes a fresh air mechanism 100.

[0034] Specifically, the fresh air mechanism 100 includes a casing 101 for placing various components, a cover 102 is detachably installed on the top of the casing 101, and an air inlet duct 103 and an air outlet duct 108 are respectively provided on both sides of the outside of the casing 101, and a fan 104, a transition sleeve 105 located at one end of the fan 104, a dust removal module 106 located outside the transition sleeve 105, and a heat exchange module 107 located outside the dust removal module 106 are sequentially installed between the air inlet duct 103 and the air outlet duct 108.

[0035] Furthermore, the air inlet duct 103, the fan 104, the transition sleeve 105, the dust removal module 106, the heat exchange module 107 and the air outlet duct 108 are connected in sequence, so that the outside air, under the action of the negative pressure generated by the fan 104, first enters the transition sleeve 105 through the air inlet duct 103 and the fan 104, and then enters the dust removal module 106 for dust filtration, and finally passes through the constant temperature treatment of the heat exchange module 107, and the temperature is adjusted according to the season to reduce indoor heat loss, and finally enters the room through the air outlet duct 108.

[0036] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a primary filtering mechanism 200 of the fresh air exchange device, which solves the problem that the dust removal module 106 in the fresh air exchange device has a heavy workload under large air volume conditions and the dust removal effect is easily affected.

[0037] Specifically, the primary filter mechanism 200 includes a wind sensing member 201 coaxially and rotatably installed inside the transition sleeve 105 , a power member 202 is arranged on the inner side of the wind sensing member 201 , an adjusting member 203 is connected to the outer side of the power member 202 , and a primary filter member 204 is arranged on the adjusting member 203 .

[0038] Furthermore, the wind sensing part 201 includes a wind ring 201a movably arranged inside the connecting end of the transition sleeve 105 and the dust removal module 106, and blades 201b are arranged on the inner wall of the wind ring 201a. The outer side of the air duct is also fixedly connected with an outer ring 201c, and the outer ring 201c is located inside the connecting end of the transition sleeve 105 and the fan 104. At the same time, a return spring 201d is arranged on the outside of the outer ring 201c, and the return spring 201d is located between the outer side of the outer ring 201c and the inner wall of the transition sleeve 105. The return spring 201d can be compressed by the outer ring 201c during rotation, and the outer ring 201c can be quickly reset by the elastic force of the return spring 201d when the force stops being applied to the outer ring 201c.

[0039] The power part 202 includes a traction seat 202a fixedly arranged on the inner wall of the outer ring 201c, a traction groove is reserved on the surface of the traction seat 202a opposite to the axis of the transition sleeve 105, and an insert head 202c is movably embedded inside the traction groove, one end of the insert head 202c is fixedly connected to a pull rod 202d, and a push column 202e is integrally arranged on the outer wall of the pull rod 202d.

[0040] The adjusting member 203 includes a base plate 203a fixed to the inner wall of the transition sleeve 105, a rotatable drum 203b is installed on the surface of the base plate 203a, and the pull rod 202d and the push column 202e are located inside the drum 203b, a rotating groove is left on the inner wall of the drum 203b, and a center groove 203d is set in the middle section of the outer wall of the drum 203b, and an offset groove 203e is also left on the outer wall that rotates away from the center groove 203d.

[0041] The primary filter element 204 includes a baffle 204a, a moving head 204b is fixedly disposed on one end of the baffle 204a, and a guide rail 204c is disposed on the other end of the baffle 204a.

[0042] Preferably, the blades 201b are tiltedly arranged in a circular array on the inner wall of the inner ring, so that when the airflow sucked in by the fan 104 passes through the blades 201b, the blades 201b can be pushed to cause the outer ring 201c and the inner ring to rotate. At the same time, under the elastic force limitation of the return spring 201d, the thrust difference generated by the airflow with different intake volumes can realize the graded deflection of the outer ring 201c.

[0043] The traction seat 202a is arranged in a slope, and the traction groove is opened with equal depth along the slope of the surface of the traction seat 202a. Therefore, when the traction seat 202a rotates with the outer ring 201c, under the relative rotation of the traction seat 202a and the insert head 202c, the distance between the two can change when each point on the traction seat 202a is in the same straight line with the rotating drum 203b, so that when the traction seat 202a deflects, the pull rod 202d can move along its axial direction inside the rotating drum 203b.

[0044] The rotating groove is spirally arranged along the inside of the rotating drum 203b, and the rotating groove and the push column 202e are slidingly matched. Therefore, when the pull rod 202d moves along its axial direction inside the rotating drum 203b, it can act on the rotating groove in the displacement direction of the push column 202e, pushing the rotating groove to offset, so as to meet the smooth movement of the push column 202e inside the rotating groove, thereby achieving the purpose of rotating the rotating drum 203b.

[0045] The baffles 204a are arranged in a horizontal array on the drum 203b, and the moving heads 204b can cooperate with the central groove 203d or the offset groove 203e respectively. The baffles 204a that are not arranged in a linear array can form a grille. When the airflow passes through, the dust and impurities in the airflow are initially blocked and filtered by the grille to reduce the purification burden of the dust removal component. At the same time, the other end of the baffle 204a is located inside the guide rail 204c fixed on the inner wall of the transition sleeve 105, so that the guide rail 204c guides and limits the displacement of the baffle 204a to ensure the smooth movement of the baffle 204a.

[0046] Furthermore, a plurality of offset grooves 203e are provided on the rotating drum 203b along its axial direction, and the projected lengths of the plurality of offset grooves 203e on the axial direction of the rotating drum 203b increase proportionally. At the same time, two groups of the plurality of offset grooves 203e are symmetrically provided on the rotating drum 203b about the central groove 203d, that is, the central groove 203d is provided in the middle section of the outer wall of the rotating drum 203b, and a plurality of offset grooves 203e with gradually changing inclination angles are symmetrically provided on both sides thereof. When the moving head 204b cooperates with the central groove 203d, since the central groove 203d is provided horizontally, during the rotation of the rotating drum 203b, the moving head 204b is aligned with the central groove 203d. The baffle 204a corresponding to 03d is always in the middle position and will not move. At the same time, the moving head 204b matched with the offset grooves 203e on both sides realizes synchronous displacement with the rotation of the rotating drum 203b under the push of multiple inclined grooves with inclined settings and increasing projection lengths in geometric proportion. The position distance of each moving head 204b also increases exponentially. Therefore, when the rotating drum 203b rotates, it can drive multiple baffles 204a to translate synchronously along the guide rail 204c, thereby realizing the adjustment of the spacing between the baffles 204a and ensuring that the distance between each baffle 204a always remains consistent.

[0047] When in use, the fan 104 is turned on, and the air intake of the fan 104 can be adjusted in multiple stages according to the actual needs of the user. Therefore, under different air volumes and wind forces, the elastic force of the return spring 201d can be counteracted, and the inner ring and the outer ring 201c can be driven to deflect at different angles by the action on the blade 201b. Subsequently, the pull rod 202d can be moved along its axial direction inside the rotating drum 203b under the relative sliding between the traction seat 202a and the embedded head 202c. At this time, the rotating drum 203b can be rotated accordingly through the cooperation between the push column 202e and the rotating groove. Finally, the central groove 203d and the offset groove 203e correspondingly opened on the surface of the rotating drum 203b act on each moving head 204b, and the corresponding baffle 204a on the offset groove 203e moves synchronously on the guide rail 204c, so that the distance between the baffles 204a can be adaptively adjusted according to the air intake volume.

[0048] In summary, through the setting of the wind sensing member 201, the amount of air entering the device is sensed, thereby driving the traction seat 202a to deflect at a corresponding angle, and then the distance between the baffles 204a is adjusted through the cooperation between the pull rod 202d and the rotating drum 203b. When the air intake is small, the dust removal load of the dust removal module 106 is small. At this time, the distance between the baffles 204a can be in a larger state to ensure the smooth flow of airflow. When the air intake is large, the dust removal load of the dust removal module 106 is large. At this time, the distance between the baffles 204a can be adjusted accordingly to make the distance smaller, so that the dust in the airflow can be initially filtered and the airflow velocity can be reduced to reduce the load of the dust removal module 106 and ensure the dust removal module 106 The purification effect of the airflow.

[0049] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, provides an air conditioner, including embodiment 1 and embodiment 2, and:

[0050] Two groups of power parts 202, adjusting parts 203 and primary filter parts 204 are arranged inside the transition sleeve 105, and the angle between the two groups of power parts 202, adjusting parts 203 and primary filter parts 204 is 90°, and the two groups of power parts 202, adjusting parts 203 and primary filter parts 204 are stacked. By stacking the two groups of primary filter parts 204 and vertically arranging them, a plurality of square through holes can be formed between the two groups of baffles 204a, thereby further realizing the primary filtration of the airflow, improving the primary filtration effect of the primary filter part 204 on the airflow, and ensuring that the purpose of reducing the load on the dust removal module 106 is successfully achieved.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
