[0001] This application relates to the field of smart home appliance technology, and in particular to a jet device and an air conditioner. Background Technology

[0035] Unless otherwise stated, the term "multiple" means two or more.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0037] Combination Figure 1-6 As shown, in some embodiments, a jet device includes: an annular air passage 100, a rotating part 200, an annular air outlet 300, and a jet port 201. The annular air passage 100 is provided with a guide port 101; the rotating part 200 is annular, and one side of its axial direction is rotatably connected to the side of the annular air passage 100 in the axial direction; the annular air outlet 300 is rotatably connected to the other side of the rotating part 200 in the axial direction, and the annular air outlet 300 is provided with a guide channel 301 offset towards the center; the jet port 201 is disposed on the rotating part 200, and one end is connected to the annular air passage 100, and the other end is connected to the guide channel 301.

[0038] The jet device provided in this embodiment is designed for circular air conditioning outlets using an annular air outlet shroud 300, making it easy to set along the circular air conditioning outlet. The jet port 201 of the jet device is set on the rotating part 200 and connects the annular air passage 100 and the guide channel 301. The position of the jet port 201 can be adjusted by rotating the rotating part 200. Airflow is injected into the guide channel 301 through the jet port 201. Under the guidance of the guide channel 301, the airflow deviates towards the center of the annular air outlet shroud 300, causing the airflow of the air conditioner to shift. The jet outlet position is different when the jet port 201 is rotated to different positions. By changing the jet position, the overall airflow of the air conditioner can be changed, thereby giving the air conditioner a variety of airflow modes to meet people's diverse needs for airflow modes.

[0039] Optionally, the annular airway 100 is connected to the drainage channel 102 via the drainage port 101. In this way, airflow is introduced into the annular airway 100 through the drainage channel 102 and the drainage port 101, thereby improving drainage efficiency.

[0040] Optionally, the drainage channel 102 is connected to the fan 400. In this way, the fan 400 provides the power for drainage, further improving the drainage efficiency.

[0041] Optionally, the fan 400 includes a centrifugal impeller 401, an impeller motor 402, and a drive shaft 403. The centrifugal impeller 401 is disposed inside the housing of the fan 400; the impeller motor 402 is disposed outside the housing of the fan 400 and is connected to the centrifugal impeller 401 via the drive shaft 403, and is configured to drive the centrifugal impeller 401 to rotate. Thus, by driving the centrifugal impeller 401 to rotate via the impeller motor 402, and since the impeller motor 402 is connected to the centrifugal impeller 401 via the drive shaft 403, the centrifugal impeller 401 is separated from the impeller motor 402. Given the axial air intake and radial air exhaust characteristics of the centrifugal impeller 401, air can enter from both ends of the centrifugal impeller 401 in the axial direction, improving the air intake efficiency of the fan 400, thereby further improving the drainage efficiency.

[0042] Optionally, the fan 400 includes an impeller motor 402 and centrifugal impellers 401. The impeller motor 402 has output shafts at both ends in its axial direction; two centrifugal impellers 401 are provided, each connected to the output shaft of the impeller motor 402. Thus, by connecting the two centrifugal impellers 401 to the output shafts at both ends of the impeller motor 402, and using one impeller motor 402 to simultaneously drive the two centrifugal impellers 401 to rotate, the axial air intake and radial air exhaust characteristics of the centrifugal impellers 401, with two air intake ends in their axial direction, improve the air intake efficiency of the fan 400, thereby improving the airflow efficiency.

[0043] Optionally, an air inlet 404 is provided on the fan 400 housing corresponding to the air inlet end of the centrifugal impeller 401 along the axial direction. In this way, the air inlet 404 on the fan 400 housing improves the air intake efficiency and thus improves the diversion efficiency due to the axial air intake characteristic of the centrifugal impeller 401.

[0044] Optionally, the rotating part 200 includes an outer ring part 202, an inner ring part 203, and a radial connecting part 204. The outer ring part 202 and the inner ring part 203 are connected by the radial connecting part 204, and the jet port 201 is disposed through the radial connecting part 204. In this way, an annular space is defined between the outer ring part 202 and the inner ring part 203, and the annular space is blocked radially by the radial connecting part 204. The jet port 201, which passes through the axial direction of the annular space, is provided on the radial connecting part. After the airflow enters the annular space, the dynamic pressure is converted into static pressure, and then it is ejected through the jet port 201, which increases the flow velocity of the airflow ejected from the jet port 201 and improves the jetting effect.

[0045] Optionally, the jet nozzle 201 is arranged in a fan-shaped annular configuration. This fan-shaped annular structure of the jet nozzle 201 ensures that the airflow ejected from the jet nozzle 201 forms a uniform fan-shaped annular pattern, thereby improving the jetting effect.

[0046] Optionally, the width of the jet outlet 201 is the same as the radial width of the radial connecting portion 204. In this way, since the radial connecting portion 204 is generally annular, setting the shape of the jet outlet 201 to a fan-shaped annulus, and arranging the jet outlet 201 along the contour of the radial connecting portion 204, increases the flow area of ​​the jet outlet 201 when its width is the same as the radial width of the radial connecting portion 204. This allows the jet outlet 201 to have sufficient airflow, improving its jetting effect.

[0047] Understandably, the width of the jet orifice 201 refers to the radial distance between the outer and inner arcs of the fan-shaped annular structure.

[0048] Optionally, the jet nozzle 201 has a preset arc, which is greater than or equal to one-sixth of π and less than or equal to one-third of π. This gives the jet nozzle 201 a certain flow area. When the preset arc is less than one-sixth of π, the central angle corresponding to the fan-shaped annular jet nozzle 201 is less than 30°. In this case, the arc length corresponding to the fan-shaped annular jet nozzle 201 is small, the flow area of ​​the jet nozzle 201 is small, and the airflow rate ejected from the jet nozzle 201 is small, reducing the jet efficiency of the jet nozzle 201. When the preset arc is greater than one-third of π, the central angle corresponding to the fan-shaped annular jet nozzle 201 is greater than 60°. The arc is relatively large, the flow area of ​​the jet nozzle 201 is large, and the pressure of the airflow ejected from the jet nozzle 201 is low, which reduces the air delivery distance. Therefore, when the preset arc is greater than or equal to one-sixth of π and less than or equal to one-third of π, the central angle corresponding to the fan-shaped jet nozzle 201 is greater than or equal to 30° and less than or equal to 60°. At this time, the flow area of ​​the fan-shaped jet nozzle 201 is suitable for jetting. While maintaining the jetting efficiency of the jet nozzle 201, the air delivery distance is extended and the jetting effect of the jet nozzle 201 is improved.

[0049] Optionally, the preset radius is one-quarter of a π. In this case, with the preset radius of one-quarter of a π, the central angle corresponding to the annular jet nozzle 201 is 45°. At this time, the flow area of ​​the jet nozzle 201 is moderate, which extends the air delivery distance and improves the jet effect of the jet nozzle 201 while maintaining the jet efficiency of the jet nozzle 201.

[0050] Optionally, the outer ring portion 202 and the inner ring portion 203 have a predetermined distance in their radial direction, and the predetermined distance is greater than or equal to one-sixth of the radius of the inner ring portion 203 and less than or equal to one-quarter of the radius of the inner ring portion 203. Thus, since the width of the jet outlet 201 is the same as the width of the radial connection portion 204, when there is a predetermined distance in their radial direction between the outer ring portion 202 and the inner ring portion 203, the jet outlet 201 has a certain width. When this jet device is installed at the air conditioner outlet, the airflow of the air conditioner outlet flows through the inner ring portion 203, and the flow area of ​​the air conditioner outlet is the flow area of ​​the inner ring portion 203. When the predetermined distance is less than one-sixth of the radius of the inner ring portion, the outer ring portion 202 and the inner ring portion 203 have a predetermined distance in their radial direction. The inner ring 203 has a smaller radial distance, and the width of the radial connection 204 connecting the outer ring 202 and the inner ring 203 is also smaller. This results in a narrower jet port 201 on the radial connection 204, leading to a smaller flow area compared to the inner ring 203. Consequently, the jet efficiency of the jet port 201 is lower, making it difficult to deflect the airflow from the air conditioner outlet. When the preset distance is greater than one-quarter of the inner ring radius, the outer ring 202 and the inner ring 203... The radial distance is relatively large, and the width of the radial connecting portion 204 connecting the outer ring portion 202 and the inner ring portion 203 is also relatively large. This results in a wider jet nozzle 201 on the radial connecting portion 204, and the flow area of ​​the jet nozzle 201 is larger than that of the inner ring portion 203. The airflow pressure from the jet nozzle 201 is lower, and the flow velocity is slower, reducing the air delivery distance and affecting the impact of the jet airflow on the air conditioner's outlet airflow. Therefore, when the preset distance is greater than or equal to one-sixth of the inner ring radius and less than... When the radius of the outer ring 202 is equal to or equal to one-quarter of the inner ring radius, the radial distance between the outer ring 202 and the inner ring 203 is moderate, resulting in a moderate width of the jet port 201 provided on the radial connection 204. The ratio between the flow area of ​​the jet port 201 and the flow area of ​​the inner ring 203 is moderate. At this time, the jet airflow can better drive the airflow of the air conditioner to deflect, thereby changing the overall airflow of the air conditioner and enabling the air conditioner to have a variety of airflow modes to meet people's diverse needs for airflow modes.

[0051] Optionally, the preset distance is one-fifth of the inner ring radius. In this way, when the preset distance is one-fifth of the inner ring radius, the radial distance between the outer ring 202 and the inner ring 203 is moderate, resulting in a moderate width of the jet port 201 provided on the radial connecting part 204. At this time, the ratio between the flow area of ​​the jet port 201 and the flow area of ​​the inner ring 203 is moderate, and the jet airflow can better drive the airflow of the air conditioner to deflect, thereby changing the overall airflow of the air conditioner.

[0052] Optionally, the annular air passage 100 and the rotating part 200 are rotatably connected by an annular groove connection structure. This makes the connection between the rotating part 200 and the annular air passage 100 more stable, and the sealing between the annular air passage 100 and the rotating part 200 after connection is better, which facilitates the rotating part 200 to rotate and jet on the annular air passage 100, thereby improving the jetting effect.

[0053] Optionally, the annular groove connection structure includes an annular raised groove 205 and an annular recessed groove 206. The annular raised groove 205 is confined within the annular recessed groove 206 for rotation. One of the annular raised groove 205 and the annular recessed groove 206 is disposed on the annular air passage 100, and the other is disposed on the rotating part 200. Thus, the rotating part 200 and the annular air passage 100 are rotatably connected by the structure of the annular raised groove 205 and the annular recessed groove 206. The annular raised groove 205 engaging with the annular recessed groove 206 forms a rotatable support structure, thereby rotatably connecting the rotating part 200 and the annular air passage 100. Because the annular raised groove 205 engages with the annular recessed groove 206 after rotational connection, the sealing at the connection between the rotating part 200 and the annular air passage 100 is enhanced, improving the stability of the rotating part 200 during rotation and facilitating the rotating jet of the rotating part 200 on the annular air passage 100, thus improving the jetting effect.

[0054] Optionally, one axial end of the annular air passage 100 is engaged between the outer ring portion 202 and the inner ring portion 203 of the rotating part 200. This engagement of one axial end of the annular air passage 100 between the outer ring portion 202 and the inner ring portion 203 of the rotating part 200, and subsequent connection via an annular thread structure, further enhances the sealing at the connection between the rotating part 200 and the annular air passage 100, improves the stability of the rotating part 200 during rotation, facilitates the rotational jet of the rotating part 200 on the annular air passage 100, and improves the jetting effect.

[0055] Optionally, the annular air passage 100 is connected to the inner ring portion 203, and the annular air passage 100 is connected to the outer ring portion 202, both via annular groove connection structures. This connection between the annular air passage 100 and the inner ring portion 203 via annular groove connection structures makes the connection between the annular air passage 100 and the inner ring portion 203 more stable, further enhancing the sealing at the connection between the rotating portion 200 and the annular air passage 100, improving the stability of the rotating portion 200 during rotation, facilitating the rotating jet of the rotating portion 200 on the annular air passage 100, and improving the jetting effect.

[0056] Optionally, annular ridges 205 are disposed on the outer and inner annular surfaces of the annular air passage 100, and annular grooves 206 are disposed on the inner wall of the outer annular portion 202 and the outer wall of the inner annular portion 203 of the rotating part 200. In this way, the annular ridges 205 disposed on the outer and inner annular surfaces of the annular air passage 100 are engaged with the annular grooves 206 disposed on the inner wall of the outer annular portion 202 and the outer wall of the inner annular portion 203 of the rotating part 200, thereby achieving a rotational connection between the rotating part 200 and the annular air passage 100. This results in better sealing at the connection between the rotating part 200 and the annular air passage 100, and greater stability of the rotating part 200 during rotation. This facilitates the rotating jet of the rotating part 200 on the annular air passage 100, improving the jetting effect.

[0057] Combination Figure 7-9 As shown, in some optional embodiments, the annular air outlet shroud 300 is provided with multiple guide channels 301, and the flow area of ​​the inlet of each guide channel 301 is the same as the flow area of ​​the jet port 201. Thus, when the annular air outlet shroud 300 is installed on the air conditioner outlet, the guide channels 301 guide the airflow ejected from the jet port 201. The airflow ejected from the jet port 201 causes the air conditioner's outlet airflow to deflect. Since the flow area of ​​the guide channel 301 inlet is the same as the flow area of ​​the jet port 201, the airflow ejected from the jet port 201 can smoothly enter the guide channel 301, thereby better driving the overall change of the air conditioner's airflow, and thus enabling the air conditioner to have a variety of airflow modes to meet people's diverse needs for airflow modes.

[0058] Optionally, the inner ring surface 302 of the annular air outlet shroud 300 is provided as an inclined surface or an arc-shaped surface, and its inner ring surface 302 defines a funnel-shaped channel 500. In this way, when the annular air outlet shroud 300 is installed at the air outlet of the air conditioner, the airflow at the air outlet of the air conditioner flows out through the annular air outlet shroud 300, and the airflow from the air conditioner is gathered and guided by the inner ring surface 302 of the annular air outlet shroud 300. The inner ring surface 302 of the annular air outlet shroud 300 can also guide the airflow ejected from the jet nozzle 201, so that the airflow ejected from the jet nozzle 201 causes the airflow from the air conditioner to deflect, thereby improving the overall air outlet effect of the air conditioner.

[0059] Optionally, the funnel-shaped channel 500 includes a wide opening 501 and a narrow opening 502. The annular air outlet shroud 300 corresponding to the wide opening 501 is rotatably connected to the rotating part 200. In this way, the airflow at the air conditioner outlet enters the funnel-shaped channel 500 through the wide opening 501, and flows out through the narrow opening 502 under the gathering and guiding effect of the inner annular surface 302 of the annular air outlet shroud 300, thereby improving the air conditioning's air outlet effect.

[0060] Optionally, multiple airflow guiding channels 301 are all disposed on the inner ring surface 302 of the annular air outlet shroud 300 and are evenly arranged along its inner ring surface 302. In this way, during the process of the rotating part 200 driving the jet outlet 201 to rotate and jet, the airflow ejected from the jet outlet 201 can enter the airflow guiding channel 301 evenly. After being guided by the airflow guiding channel 301, it causes the airflow of the air conditioner to deflect, so that the air conditioner can have a variety of air outlet modes while the air outlet is more evenly distributed.

[0061] Optionally, the guide channel 301 extends from the wide opening 501 of the trumpet-shaped channel 500 to its narrow opening 502. This allows the guide channel 301 to direct the airflow ejected from the jet nozzle 201 from the wide opening 501 to the narrow opening 502 of the trumpet-shaped channel 500, enabling the airflow ejected from the jet nozzle 201 to better deflect the airflow from the air conditioner, thereby better altering the overall airflow pattern and allowing the air conditioner to have various airflow modes.

[0062] Optionally, the shape of the inlet of the guide channel 301 is the same as the shape of the jet outlet 201. This makes the inlet of the guide channel 301 also fan-shaped, ensuring that the flow area of ​​the inlet of the guide channel 301 is the same as the flow area of ​​the jet outlet 201. This allows the airflow ejected from the jet outlet 201 to smoothly enter the guide channel 301, thereby better driving changes in the overall airflow of the air conditioner. This results in the air conditioner having a variety of airflow modes to meet diverse needs.

[0063] Optionally, four airflow channels 301 are provided, and the arc of the fan-shaped annular structure corresponding to the inlet of the airflow channel 301 is one-quarter of a π. In this way, the four airflow channels 301 are evenly arranged on the inner ring surface 302 of the annular air outlet hood 300, and the flow area of ​​the inlet of the airflow channel 301 is moderate, so that the airflow ejected from the jet nozzle 201 can smoothly enter the inlet of the airflow channel 301. When the rotating part 200 rotates to different positions, the jet nozzle 201 connects with different airflow channels 301 to eject airflow. The jet position can be changed according to the user's orientation, thereby changing the overall airflow direction of the air conditioner, so that the air conditioner can have a variety of airflow modes.

[0064] Optionally, four airflow channels 301 are sequentially positioned at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions on the inner annular surface 302 of the annular air outlet shroud 300. Thus, when the jet device is installed at the air conditioner outlet, the rotation of the rotating part 200 can connect the jet outlet 201 with one of the airflow channels 301 at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions, depending on the user's orientation. This causes the airflow from the air conditioner to be deflected towards or away from the user's orientation, improving the user experience.

[0065] Optionally, the flow area of ​​the guide channel 301 gradually decreases from the end connected to the jet port 201 to the other end. This causes the dynamic pressure of the airflow ejected from the jet port 201 to gradually convert into static pressure as it flows through the guide channel 301. The increased dynamic pressure of the airflow exiting the guide channel 301 increases the air delivery distance and improves the airflow velocity, making it easier to deflect the airflow from the air conditioner. This better influences the overall airflow pattern of the air conditioner, allowing it to offer a variety of airflow modes to meet diverse user needs.

[0066] Optionally, the flow area of ​​the guide channel 301 gradually decreases from the wide opening 501 of the trumpet-shaped channel 500 to its narrow opening 502. This gradual decrease in flow area from the wide opening 501 to the narrow opening 502 of the trumpet-shaped channel 500 causes the dynamic pressure of the airflow ejected from the jet nozzle 201 to gradually convert into static pressure as it flows through the guide channel 301. This increases the dynamic pressure of the airflow exiting the guide channel 301, improving the air delivery distance and increasing the airflow velocity. This makes it easier to deflect the airflow from the air conditioner, thus better altering the overall airflow pattern and enabling the air conditioner to offer a variety of airflow modes to meet diverse user needs.

[0067] Combination Figure 10 As shown, in some optional embodiments, the angle at which the guide channel 301 is offset towards the center is greater than or equal to 30 degrees and less than or equal to 60 degrees. Thus, when the angle of offset of the guide channel 301 towards the center is less than 30 degrees, the airflow ejected from the jet nozzle 201 is significantly offset towards the center of the annular air outlet shroud 300 under the guiding effect of the guide channel 301, resulting in a larger angle between the airflow and the airflow exiting the annular air outlet shroud 300. This leads to a larger pressure loss in the airflow when it causes the airflow to deviate. When the angle of offset of the guide channel 301 towards the center is greater than 60 degrees, the airflow ejected from the jet nozzle 201 is slightly offset towards the center of the annular air outlet shroud 300 under the guiding effect of the guide channel 301, resulting in a smaller angle between the airflow and the airflow exiting the annular air outlet shroud 300. The airflow is relatively small and does not easily cause the air conditioner's airflow to deviate, resulting in a poor effect on changing the overall airflow of the air conditioner. Therefore, when the angle of the guide channel 301 deviating towards the center is greater than or equal to 30 degrees and less than or equal to 60 degrees, the airflow ejected from the jet port 201 is appropriately deviated towards the center of the annular air outlet hood 300 under the guiding effect of the guide channel 301. The angle between the airflow and the air conditioner's airflow flowing out of the annular air outlet hood 300 is moderate, making it easy to cause the air conditioner's airflow to deviate. Moreover, the pressure loss of the airflow is small, which can better change the overall airflow of the air conditioner, thereby enabling the air conditioner to have a variety of airflow modes to meet people's diverse needs for airflow modes.

[0068] Optionally, the angle at which the guide channel 301 is offset towards the center is 45 degrees. In this way, the airflow ejected from the jet port 201 is appropriately offset towards the center of the annular air outlet shroud 300 under the guiding effect of the guide channel 301. The angle between the airflow and the airflow from the annular air outlet shroud 300 is moderate, which makes it easy to offset the airflow and minimizes the pressure loss of the airflow. This allows for better changes in the overall airflow of the air conditioner, enabling the air conditioner to have a variety of airflow modes to meet people's diverse needs for airflow modes.

[0069] like Figure 10 As shown, angle a is the angle at which the flow channel 301 is offset towards the center of the circle.

[0070] Understandably, the angle at which the flow channel 301 is offset toward the center is the angle between the air outlet direction of the flow channel 301 and the plane where the narrow nozzle 502 is located.

[0071] Combination Figure 11-12 As shown, in some alternative embodiments, the annular air passage 100 and the inner annular surface 302 of the rotating part 200 together define a cylindrical channel 600. Thus, when the jet device is installed on the air outlet of an air conditioner, the airflow from the air conditioner flows out through the cylindrical channel, then flows into the funnel-shaped channel 500 connected thereto, and flows out through the annular air outlet shroud 300.

[0072] Optionally, the jet device further includes a guide seat 601. The guide seat 601 is disposed on one side of the cylindrical channel 600. In this way, the airflow passing through the air outlet of the air conditioner is guided by the guide seat 601, thereby improving the air outlet effect of the air conditioner.

[0073] Optionally, the air guide seat 601 extends into the cylindrical channel 600, forming a uniform annular airflow channel between itself and the inner annular surface 302 of the annular air passage 100 and the rotating part 200. This allows the airflow from the air conditioner outlet to flow out evenly through the annular airflow channel under the guidance of the air guide seat 601, improving the air conditioning's airflow efficiency.

[0074] Optionally, the air guide seat 601 has a cylindrical structure, with one end protruding from a spherical part 602 based on a circular end face. A portion of the spherical part 602 extends into the flared channel 500 defined by the inner ring surface 302 of the annular air outlet shroud 300. Thus, because a portion of the spherical part 602 extends into the flared channel 500, it can guide the airflow ejected from the jet nozzle 201, further altering the overall airflow pattern of the air conditioner. This allows the air conditioner to have various airflow modes, meeting diverse needs for different airflow patterns.

[0075] Combination Figure 13As shown, in some optional embodiments, the rotating part 200 and the annular air outlet shroud 300 are connected by a protruding connecting structure, which includes an annular groove 700 and an annular protrusion 701. The annular protrusion 701 is confined within the annular groove 700 for rotation; wherein, one of the annular groove 700 and the annular protrusion 701 is disposed on one side of the rotating part 200, and the other is disposed on one side of the annular air outlet shroud 300. In this way, the rotational connection between the rotating part 200 and the annular air outlet shroud 300 is achieved by the annular protrusion 701 engaging with the annular groove 700. Since the annular protrusion 701 engages with the annular groove 700 after rotational connection, the sealing at the connection between the rotating part 200 and the annular air outlet shroud 300 is enhanced, the stability of the rotating part 200 during rotation is improved, and the rotating part 200 can easily rotate and jet on the annular air outlet shroud 300, thereby improving the jetting effect.

[0076] Optionally, an annular groove 700 is provided on the side where the annular air outlet shroud 300 connects to the rotating part 200, and an annular protrusion 701 is provided on the side where the rotating part 200 connects to the annular air outlet shroud 300. In this way, the annular protrusion 701 on one side of the rotating part 200 is inserted into the annular groove 700 on one side of the annular air outlet shroud 300 to achieve a rotational connection between the rotating part 200 and the annular air outlet shroud 300. Because the annular protrusion 701 is inserted into the annular groove 700 after rotational connection, the sealing at the connection between the rotating part 200 and the annular air outlet shroud 300 is enhanced, the stability of the rotating part 200 during rotation is improved, and the rotating part 200 can easily rotate and jet onto the annular air outlet shroud 300, thus improving the jetting effect.

[0077] Optionally, both the outer and inner circumferences of the rotating part 200 are rotatably connected to the annular air outlet shroud 300 via a protruding connecting structure. Thus, since the rotating part 200 has an outer and inner circumference, the provision of two protruding connecting structures to rotatably connect both the outer and inner circumferences of the rotating part 200 to the annular air outlet shroud 300 further enhances the sealing at the connection between the rotating part 200 and the annular air outlet shroud 300, improving the stability of the rotating part 200 during rotation.

[0078] Optionally, the outer ring portion 202 corresponding to the outer circumference of the rotating part 200 and the inner ring portion 203 corresponding to the inner circumference are rotatably connected to the annular air outlet shroud 300 through a protruding connecting structure. Thus, an annular protrusion 701 is provided at both the outer ring portion 202 and the inner ring portion 203 of the rotating part 200, and two annular grooves 700 corresponding to the annular protrusions 701 are provided on one side wall of the annular air outlet shroud 300. The annular protrusions 701 at the outer ring portion 202 and the inner ring portion 203 of the rotating part 200 are respectively engaged into the corresponding annular grooves 700, achieving a rotatable connection between the rotating part 200 and the annular air outlet shroud 300. This further enhances the sealing at the connection between the rotating part 200 and the annular air outlet shroud 300 and improves the stability of the rotating part 200 during rotation.

[0079] Combination Figure 14 As shown, in some optional embodiments, the jet device further includes a driving device. The driving device is connected to the rotating part 200 and configured to drive the rotating part 200 to rotate. Thus, by driving the rotating part 200 to rotate, the rotating part 200 can rotate smoothly, and the jet outlet 201 provided on the rotating part 200 rotates smoothly with the rotating part 200, thereby improving the diversity of air conditioning air output and meeting people's diverse needs for air output modes.

[0080] Optionally, the driving device includes a ring gear 800 and a motor 801. The ring gear 800 is arranged around the rotating part 200; the motor 801 has a gear at its output end, which meshes with the ring gear 800. Thus, the gear at the output end of the motor 801 drives the ring gear 800 to rotate, thereby driving the rotating part 200 to rotate. The meshing of the gear with the ring gear 800 makes the transmission between them more stable. Because the ring gear 800 is arranged around the rotating part 200, the jet outlet 201 on the rotating part 200 rotates smoothly with the rotating part 200, improving the diversity of air conditioning air output and meeting people's diverse needs for air output modes.

[0081] Optionally, multiple motors 801 are provided, and the multiple motors 801 are evenly distributed along the annular gear 800. In this way, the annular gear 800 can be driven simultaneously by multiple motors 801. Since the multiple motors 801 are evenly distributed along the annular gear 800, the annular gear 800 is subjected to uniform force, which further improves the rotational stability of the rotating part 200, enhances the diversity of air conditioning air output, and meets people's diverse needs for air output modes.

[0082] Combination Figure 15-16 As shown, in some embodiments, an air conditioner includes the jetting device of any of the above embodiments.

[0083] Optionally, the air conditioner also includes a housing 900. A circular air outlet 901 is provided on the housing 900, and an annular air outlet shroud 300 is installed inside the circular air outlet 901. In this way, by installing the annular air outlet shroud 300 at the circular air outlet 901 of the air conditioner, the air is discharged through the annular air outlet shroud 300 instead of the circular air outlet 901. The annular air outlet shroud 300 can gather and guide the airflow from the air conditioner, improving the air outlet efficiency.

[0084] Optionally, the housing 900 includes a flow guide bracket. The flow guide 601 is connected to the housing 900 via the flow guide bracket. Thus, when the jet device is installed and used in an air conditioner, the flow guide 601 in the jet device is supported by the flow guide bracket, improving the stability of the flow guide 601.

[0085] Optionally, the housing 900 further includes an air outlet cavity 902. The air outlet cavity 902 is disposed within the housing 900 and communicates with the circular air outlet 901. In this way, the airflow in the air conditioner flows through the air outlet cavity 902 to the circular air outlet 901, and then flows out through the annular air outlet cover 300, thereby improving the air outlet effect of the air conditioner.

[0086] Optionally, the air outlet cavity 902 is connected to the air diversion channel 102. In this way, the air diversion channel 102 can directly divert the air conditioning airflow in the air outlet cavity 902, thereby improving the diversion effect.

[0087] Optionally, a motor mount 903 is provided on the air outlet cavity 902, and the motor 801 is mounted on the motor mount 903. In this way, the motor 801 is mounted on the motor mount 903, and the motor mount 903 supports the motor 801, thereby improving the stability of the motor 801.
