Optionally, the grid structure is a mesh-like structure or an elongated hole-like structure. In the particular embodiment shown in fig. 3, the grating structure is formed of a plurality of arcuate elongated hole-like structures to form an elliptical grating structure.

The inlet of the blower 20 in the present invention is directed towards the air intake structure 13. In this way, it is ensured that air outside the housing 10 is sucked into the housing 10 through the air intake structure 13 by the fan 20 and blown out through the air outlet.

Alternatively, the fan 20 is a centrifugal fan or a cross-flow fan. When the blower 20 is a cross flow blower, the housing 10 needs to be further elongated to reserve a sufficient installation space for the cross flow blower.

In the embodiment shown in fig. 1-8, the air intake structure 13 is located in the rear half of the housing 10 directly opposite the inlet end of the blower 20.

The housing 10 in the present invention is an egg-shaped structure or a spherical structure. Preferably an egg-shaped structure. The egg-shaped structure of the housing 10 has the characteristic of attractive appearance.

In order to ensure that the air supply device can be reliably placed, the air supply device further comprises a base, and the housing 10 is arranged on the base. By providing the base, the housing 10 can be fixed to ensure reliable air supply of the air supply device.

Thus, the first air outlet 11 has high-speed air flow and supplies air forward. The second air outlet 12 is staggered with the first air outlet 11 and has different air outlet directions so as to enlarge the air supply range. The user can control the use state of the air outlet according to the indoor environment and the requirements.

Example 1

In this embodiment, the first air outlet 11 and the second air outlet 12 are both annular air outlets. In this way, the second air outlet 12 can also blow out high-speed air flow, which is beneficial to improving the air supply efficiency.

As shown in fig. 1 to 7, the air supply device further includes a protection cover 80, the protection cover 80 is disposed in the second air outlet 12, and an annular air outlet is formed between an outer edge of the protection cover 80 and a periphery of the second air outlet 12. By providing the protection cover 80, the second air outlet 12 can be formed in a ring shape. In this way, the air flow velocity there is increased.

As shown in fig. 1 to 7, the second air outlet 12 is disposed forward.

Specifically, the second air outlet 12 is near the front end of the casing 10 with respect to the rear end of the casing 10. In this way, the air blowing device can intensively blow forward through the first air outlet 11, and can blow forward obliquely through the second air outlet 12. In general, when many people are present, both the first air outlet 11 and the second air outlet 12 may be opened. And when the person is reduced, the first air outlet 11 or the second air outlet 12 may be selectively closed.

As shown in fig. 1 to 7, the second air outlets 12 are plural, and the plural second air outlets 12 are disposed at intervals around the circumference of the casing 10. Therefore, the air supply device can not only concentrate air outlet forward in the middle part, but also circumferentially disperse the air outlet, so that the air outlet radiation range is wider, and the reliability of air supply is improved.

In the embodiment shown in fig. 1 to 7, the air supply device further includes an inner casing 40 and a guide sleeve 30, where the guide sleeve 30 and the inner casing 40 are both disposed in the outer casing 10, at least a portion of the inner casing 40 is located in the guide sleeve 30, a first end of the guide sleeve 30 is connected to an outer ring edge of the first air outlet 11, and an annular air outlet is formed between the guide sleeve 30 and an outer surface of the inner casing 40. The inner casing 40 and the guide sleeve 30 are mainly used for forming an annular air outlet so as to ensure the concentration and high fluidity of the air outlet in the middle part.

As shown in fig. 1 to 7, the inner case 40 has an opening structure toward the front end of the outer case 10, and the outer case 10 has a relief port 14 communicating with the opening structure. It should be noted that the opening structure at the inner casing 40 does not exhaust air, mainly for increasing the aesthetic property of the air supply device. By providing the relief opening 14 in the outer shell 10, the cavity of the inner shell 40 can be exposed. Of course, the escape opening 14 may not be provided, and thus, even if the inner case 40 has an opening structure, the inner case is shielded by the outer case 10, but this does not affect the performance of the air supply.

In the embodiment shown in fig. 6 and 7, the air outlet adjusting mechanism 70 includes a spacer for adjusting the on-off state of the first air outlet 11 and the second air outlet 12, the spacer is disposed in the housing 10, the radial cross section of the spacer can be adjusted, and when the first end of the spacer is aligned with the second end of the guide sleeve 30, the spacer and the guide sleeve 30 cut off the communication state of the first air outlet 11 and the second air outlet 12; when the first end of the spacer is staggered from the second end of the guide sleeve 30 and forms the air passing gap 71, the air blown out from the air outlet of the fan 20 partially passes through the air passing gap 71 and then flows out from the second air outlet 12. In this embodiment, the air outlet adjusting mechanism 70 is not provided at the first air outlet 11, and thus the first air outlet 11 is always opened and the air outlet can be always maintained. The second air outlet 12 can not output air, and needs to be determined according to the matching condition of the spacer bush and the guide sleeve 30.

Specifically, the spacer is an elastic structure or an accordion-like structure having folds. The spacer can increase the area of the radial cross section due to elastic deformation. Or by the deployment of pleats, the radial cross-sectional area of the overall tubular structure is increased.

In order to improve the reliability of the air outlet and plan the air flow path, the air supply device further comprises an annular partition plate 90, the inner ring side of the annular partition plate 90 is connected with the outer surface of the fan 20, the outer ring side of the annular partition plate 90 is connected with the inner wall of the outer shell 10, the annular partition plate 90 divides the inner cavity of the outer shell 10 into an air inlet cavity 15 and an air outlet cavity 16, the air inlet cavity 15 and the air outlet cavity 16 are communicated only through the fan 20, the spacer bush, the guide sleeve 30 and the inner shell 40 are located in the air outlet cavity 16, and the second end of the spacer bush is in contact with the annular partition plate 90. In this way, the incoming air of the air inlet structure 13 can only enter the air outlet cavity 16 through the fan 20, so that air turbulence in the shell 10 is avoided, the air supply noise is effectively reduced, and the air supply reliability of the air supply device is improved.

In order to better understand the solution, the working principle of the air supply device in the present invention will be described in the following.

The air flow entering the air supply device from the air inlet structure 13 is divided into a first air path (see fig. 6) and a second air path (see fig. 7).

The first air flow path turns from the axial direction to the radial direction along the fan 20, and then flows out from the first air outlet 11 along the spacer.

The first half airflow path of the second air path is consistent with the first air path, flows to the second air outlet 12 along the gap between the spacer bush and the guide sleeve 30 at the rear section, and flows out through the second air outlet 12.

When the gap between the spacer and the guide sleeve 30 disappears due to the action of the spacer, the second air passage is cut off, and only the first air passage is operated, so that the air flows out from the first air outlet 11.

In this embodiment, the number of the second air outlets 12 is 6, but not limited to this number, and may be fewer or more, and the second air outlets 12 are inclined at a certain angle, so that the air flow can flow out obliquely and forward.

Example two

The difference from the first embodiment is that the second air outlet is not an annular air outlet, but a common circular air outlet. Thus, the first air outlet can generate high-speed air flow, and the air speed of the second air outlet is smaller than that of the first air outlet.

Example III

The first difference from the first embodiment is that the first air outlet and the second air outlet are both provided with the air outlet adjusting mechanism, so that the user can selectively close the first air outlet or the second air outlet to meet the air outlet requirements of different users. In order to improve wind pressure and increase wind outlet speed, the first air outlet is closed while the second air outlet is opened, so that air flow only flows along the second air path and is blown out from the second air outlet.

Example IV

The difference from the first embodiment is that the specific structure of the air outlet adjusting mechanism is different from the first embodiment.

Specifically, the air outlet adjusting mechanism comprises a movable stop plate, and the stop plate shields or avoids the air outlet. Thus, sufficient installation space needs to be reserved in the housing to ensure that the stopper plate can move freely.

Example five

Specifically, the air-out adjustment mechanism includes shutter type grille, and shutter type grille sets up in air outlet department, and when the blade of shutter type grille was opened, the air outlet was opened, and when shutter type grille was closed, the air outlet was closed. Therefore, the shutter type grille is correspondingly arranged at the first air outlet and/or the second air outlet, so that the opening and closing states of the first air outlet and/or the second air outlet can be controlled.

Example six

The difference from the first embodiment is that the specific structure of the air outlet adjusting mechanism 70 is different from that of the first embodiment.

As shown in fig. 8, the air outlet adjusting mechanism 70 includes a movable stopper cylinder, which blocks the annular air outlet when the stopper cylinder is inserted into the annular air outlet, and opens the annular air outlet when the stopper cylinder is removed. The stop cylinder is matched with the annular air outlet to control the opening and closing states of the annular air outlet, so that the air supply range and the air supply quantity of the air supply device are controlled.

In the present invention, the air outlet includes several second air outlets 12 arranged around the front half in addition to the first air outlet 11 directly in front of the front half of the air supplying device. The second air outlet 12 may be manually controlled to be closed or opened, when there are more people, the second air outlet 12 is opened, and the first air outlet 11 is controlled by the shutter type grille, so as to increase the air supply range, and the first air outlet 11 is closed to avoid insufficient wind pressure and too low air outlet velocity.
