[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figure 1-3 As shown, in some embodiments, a jet device includes: an annular airway 100, a rotating part 200, and a drainage channel 300. The rotating part 200 is rotatably connected to the annular airway 100 and includes a jet port 201, which communicates with the annular airway 100; the drainage channel 300 is also communicated with the annular airway 100.

[0039] The jet device provided in this embodiment is designed for a circular air outlet via an annular air duct 100, making it easy to install along the circular air outlet of the air conditioner. The jet port 201 of the jet device is located on the rotating part 200, and the position of the jet port 201 can be adjusted by rotation. The air outlet position of the jet is different when the jet port 201 is rotated to different positions. By changing the jet position, the overall air outlet of the air conditioner can be changed, thereby enabling the air conditioner to have a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0040] Optionally, the inner annular surface 102 of the annular air duct 100 is provided as an inclined surface or an arc-shaped surface, and the inner annular surface 102 defines a funnel-shaped channel 400. In this way, when the annular air duct 100 is installed and used on an air conditioner with an air outlet, when the air outlet airflow passes through the funnel-shaped channel 400, the inner annular surface 102 of the annular air duct 100 can concentrate and guide the flowing airflow, making the air outlet more concentrated and improving the air outlet effect.

[0041] Optionally, the funnel-shaped channel 400 has a wide opening 401 at one end and a narrow opening 402 at the other end. In this way, when the annular air duct 100 is installed and used on an air conditioner, the airflow inside the air conditioner enters the funnel-shaped space defined by the inner annular surface 102 of the annular air duct 100 through the wide opening 401, and flows out from the narrow opening 402 under the converging and guiding effect of the inner annular surface 102, making the airflow more concentrated and improving the airflow effect.

[0042] Optionally, the inner annular surface 102 of the annular air duct 100 is inclined. This causes the inner diameter of the trumpet-shaped channel 400 to gradually decrease from its wide opening 401 to its narrow opening 402. When the annular air duct 100 is installed in an air conditioner, it can more evenly gather and guide the airflow passing through the air conditioner outlet.

[0043] Optionally, the annular air duct 100 has a preset width in its axial direction. This ensures that the inner annular surface 102 of the annular air duct 100 has a certain width in its axial direction. When the annular air duct 100 is installed at the air outlet 801 of an air conditioner, the appropriate width of the inner annular surface 102 of the annular air duct 100 helps to concentrate and guide the airflow passing through the air outlet 801, making the airflow more concentrated and improving the airflow effect.

[0044] Optionally, the preset width is L, and 5cm≤L≤10cm. Thus, when the preset width of the annular air duct 100 is less than 5cm, the inner annular surface 102 of the annular air duct 100 has a smaller width in its axial direction, resulting in poor concentration and guidance effects. When the preset width of the annular air duct 100 is greater than 10cm, it occupies too much installation space. Therefore, when the preset width L of the annular air duct 100 is greater than or equal to 5cm and less than or equal to 10cm, the inner annular surface 102 of the annular air duct 100 can better concentrate and guide airflow in its axial direction, while also being easier to install, thereby improving the concentration and guidance effect of airflow passing through the air conditioning outlet 801.

[0045] Optionally, the preset width L is 8cm. This makes the inner ring surface 102 of the annular air duct 100 have a width of 8cm in its axial direction, so that the inner ring surface 102 of the annular air duct 100 can better gather and guide the airflow in its axial direction, while making it easier to install, thereby improving the effect of gathering and guiding the airflow passing through the air conditioning outlet 801.

[0046] Combination Figure 4-6 As shown, in some optional embodiments, the drainage channel 300 is connected to the fan 500. In this way, the fan 500 provides the drainage power to draw airflow into the drainage channel 300, thereby improving the drainage efficiency.

[0047] Optionally, the fan 500 includes a centrifugal impeller 501, an impeller motor 502, and a drive shaft 503. The centrifugal impeller 501 is disposed inside the housing of the fan 500; the impeller motor 502 is disposed outside the housing of the fan 500 and is connected to the centrifugal impeller 501 via the drive shaft 503, and is configured to drive the centrifugal impeller 501 to rotate. Thus, by driving the centrifugal impeller 501 to rotate via the impeller motor 502, and since the centrifugal impeller 501 is connected to the impeller motor 502 via the drive shaft 503, the centrifugal impeller 501 is separated from the impeller motor 502. Given the axial air intake and radial air exhaust characteristics of the centrifugal impeller 501, air can enter from both ends of the centrifugal impeller 501 in the axial direction, improving the air intake efficiency of the fan 500, thereby further improving the drainage efficiency.

[0048] Optionally, the fan 500 includes an impeller motor 502 and centrifugal impellers 501. The impeller motor 502 has output shafts at both ends in its axial direction; two centrifugal impellers 501 are provided, each connected to one of the output shafts of the impeller motor 502. Thus, by connecting the two centrifugal impellers 501 to the output shafts at both ends of the impeller motor 502, one impeller motor 502 simultaneously drives both centrifugal impellers 501 to rotate. Due to the axial air intake and radial air exhaust characteristics of the centrifugal impellers 501, which have two air intake ends in their axial direction, the air intake efficiency of the fan 500 is improved, thereby increasing the airflow efficiency.

[0049] Optionally, an air inlet 504 is provided on the fan 500 housing corresponding to the air inlet end on the axial direction of the centrifugal impeller 501. In this way, the air inlet 504 on the fan 500 housing improves the air intake efficiency and thus improves the diversion efficiency due to the axial air intake characteristic of the centrifugal impeller 501.

[0050] Combination Figure 7-8As shown, in some optional embodiments, the annular air duct 100 is provided with an annular mounting port 101, and the rotating part 200 is movably installed in the annular mounting port 101. This arrangement of the annular mounting port 101 facilitates the installation of the rotating part 200, allowing it to rotate more effectively within the port. During rotation, the rotating part 200 maintains constant communication between the jet port 201 and the interior of the annular air duct 100. When the annular air duct 100 is installed in an air conditioner, the airflow ejected from the jet port 201 on the rotating part 200 can deflect the airflow exiting the air conditioner's outlet, thereby providing the air conditioner with various airflow modes to meet diverse user needs.

[0051] Optionally, the annular mounting port 101 is disposed on the inner annular surface 102 of the annular air duct 100. In this way, when the annular air duct 100 is installed on an air conditioner, the airflow at the air conditioner outlet flows out through the inner annular surface 102. The rotating part 200 is movably mounted on the inner annular surface 102 of the annular air duct 100. The airflow ejected from the jet port 201 on the rotating part 200 can drive the airflow flowing out of the air conditioner outlet 801 to deflect, thereby enabling the air conditioner to have a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0052] Optionally, the distance between the annular mounting port 101 and the narrow opening 402 of the horn-shaped channel 400 is smaller than the distance between them and the wide opening 401. This allows the rotating part 200 to be mounted closer to the narrow opening 402 of the horn-shaped channel 400. When the annular air duct 100 is used in an air conditioner, the air conditioner's exhaust air is discharged through the narrow opening 402. The airflow ejected from the jet port 201 can deflect the airflow exiting the narrow opening 402, thereby changing the direction of the air conditioner's exhaust airflow. Since the position of the jet port 201 changes with the rotation of the rotating part 200, the direction of the airflow ejected from the jet port 201 also changes accordingly. This allows the air conditioner to have a variety of airflow modes, meeting diverse needs for different airflow patterns.

[0053] Optionally, the rotating part 200 is rotatably mounted in the annular mounting port 101 via a sealed bearing. In this way, since the rotating part 200 is movably mounted in the annular mounting port 101, the airtightness between the rotating part 200 and the annular air passage 100 can be enhanced by mounting the rotating part 200 via a sealed bearing, thereby reducing the loss of air pressure in the annular air passage 100.

[0054] Combination Figure 9-13As shown, in some optional embodiments, the jet device further includes a guide seat 600. The guide seat 600 is disposed on one side of the annular air duct 100. Thus, when the annular air duct 100 is installed and used in an air conditioner, the guide seat 600 disposed on one side of the annular air duct 100 can guide the airflow at the air conditioner outlet, thereby improving the air conditioner's air output effect.

[0055] Optionally, the air guide seat 600 extends into the flared channel 400, forming a uniform annular airflow channel 603 between itself and the inner annular surface 102 of the annular air duct 100. Thus, when the annular air duct 100 is installed in an air conditioner, the airflow inside the air conditioner can flow out through the annular airflow channel 603 formed between the air guide seat 600 and the inner annular surface 102 of the annular air duct 100. The airflow direction is changed by the air guide seat 600, and then it flows out evenly through the annular airflow channel 603, making the airflow from the air conditioner more uniform.

[0056] Optionally, the air guide seat 600 includes a conical portion 601 and an arc-shaped portion 602. The conical portion 601 is disposed on one side of the annular air duct 100; the arc-shaped portion 602 is disposed within the funnel-shaped channel 400 defined by the inner annular surface 102 of the annular air duct 100, and forms a uniform annular airflow channel 603 between the conical portion 601 disposed on one side of the annular air duct 100 and the inner annular surface 102 of the annular air duct 100. In this way, when the annular air duct 100 is installed in an air conditioner, the airflow at the air conditioner outlet is guided by the conical portion 601 disposed on one side of the annular air duct 100, changing its flow direction to concentrate the airflow, and then flowing out from the annular airflow channel 603 formed between the arc-shaped portion 602 and the inner annular surface 102 of the annular air duct 100, thereby making the airflow at the air conditioner outlet 801 more uniform.

[0057] Optionally, the arc-shaped portion 602 is a spherical protrusion structure that protrudes towards the opposite side of the conical portion 601, based on the circular end face of the conical portion 601. In this way, the guide seat 600 is a smooth integral structure composed of the conical portion 601 and the arc-shaped portion 602, which facilitates the flow of air along the surface of the guide seat 600, reduces pressure loss during the flow process, and improves the guiding effect.

[0058] Optionally, a portion of the arc-shaped section 602 extends from the narrow opening 402 of the trumpet-shaped channel 400. Thus, when the airflow at the air conditioner outlet flows evenly through the annular airflow channel 603 formed between the arc-shaped section 602 and the inner annular surface 102 of the annular air passage 100, the portion of the arc-shaped section 602 extending from the narrow opening 402 can guide the airflow flowing out through the annular airflow channel 603, thereby changing the direction of the airflow flowing out of the annular airflow channel 603, diversifying the air conditioner's airflow direction, and meeting people's diverse needs for airflow modes.

[0059] Optionally, the maximum distance between the extended portion of the arc-shaped part 602 and the plane containing the narrow opening 402 is H, where 2cm ≤ H ≤ 5cm. Thus, when H is less than 2cm, the portion of the arc-shaped part 602 extending beyond the plane of the narrow opening 402 is small, resulting in poor airflow guidance within the annular airflow channel 603. When H is greater than 5cm, the portion of the arc-shaped part 602 extending beyond the plane of the narrow opening 402 is large, causing most of the airflow from the annular airflow channel 603 to collide with the arc-shaped surface of the extended portion of the arc-shaped part 602, resulting in a larger overall pressure loss and poorer airflow guidance. Therefore, when H is greater than or equal to 2cm and less than or equal to 5cm, the portion of the arc-shaped part 602 extending beyond the narrow opening 402 can better guide the airflow from the annular airflow channel 603, with less pressure loss, thus diversifying the airflow direction of the air conditioner.

[0060] Optionally, the maximum distance H between the portion of the arc-shaped part 602 extending out of the narrow opening 402 and the plane where the narrow opening 402 is located is 3 cm. In this way, when the maximum distance between the extended portion of the arc-shaped part 602 and the plane where the narrow opening 402 is located is 3 cm, the airflow flowing out of the annular airflow channel 603 can collide with the arc-shaped surface of the plane where the arc-shaped part 602 extends out of the narrow opening 402, changing the flow direction, improving the guiding effect, and reducing the pressure loss of the airflow.

[0061] Optionally, the tangential surface at the intersection of the curved portion 602 and the plane containing the narrow opening 402 has a preset angle with the plane containing the narrow opening 402. In this way, the portion of the curved portion 602 extending beyond the narrow opening 402 can guide the airflow flowing out through the annular airflow channel 603, thereby changing the direction of the airflow flowing out of the annular airflow channel 603 and increasing the air delivery distance.

[0062] Optionally, the preset included angle is α, where 30° ≤ α ≤ 60°. Thus, when the preset included angle is greater than or equal to 30° and less than or equal to 60°, the portion of the arc-shaped part 602 extending from the narrow opening 402 can better guide the airflow exiting through the annular airflow channel 603, and the pressure loss of the airflow is smaller, allowing for more diverse airflow directions from the air conditioner. For example... Figure 13 The included angle α shown is the preset included angle between the tangent at the intersection of the plane where the arc-shaped part 602 and the plane where the narrow opening 402 are located and the plane where the narrow opening 402 is located.

[0063] Optionally, the preset included angle α is 45°. In this way, when the tangent at the intersection of the plane where the arc-shaped part 602 and the plane where the narrow opening 402 are located has an included angle of 45° with the plane where the narrow opening 402 is located, the part of the arc-shaped part 602 extending out of the narrow opening 402 can better guide the airflow flowing out through the annular airflow channel 603, and the pressure loss of the airflow after guidance is small.

[0064] Combination Figure 14-15As shown, in some optional embodiments, the diversion channel 300 is connected to the upper half of the annular air duct 100. Thus, when this jet device is used in an air conditioner, since the airflow within the air conditioner flows from bottom to top, when the annular air duct 100 is installed at the air outlet of the air conditioner, connecting the diversion channel 300 to the upper half of the annular air duct 100 minimizes the mutual turbulence between the diversion channel 300 and the air conditioner's own airflow, facilitating both the air outlet of the air conditioner and the diversion channel 300.

[0065] Optionally, the flow channel 300 is connected to the annular air passage 100 via the diversion chamber 301. In this way, the airflow introduced into the flow channel 300 can be evenly distributed into the annular air passage 100 through the diversion chamber 301, so that the air pressure in the annular air passage 100 tends to be balanced, which facilitates the ejection of a uniformly pressurized airflow at the jet port 201.

[0066] Optionally, the flow divider 301 is provided with a figure-eight shaped guide vane 302. In this way, the figure-eight shaped guide vane 302 guides the airflow in the flow divider 301 to different directions, thereby reducing the pressure loss caused by the collision between the divided airflow and the inner wall of the annular air passage 100, increasing the pressure in the annular air passage 100, and facilitating the airflow to be ejected from the jet port 201.

[0067] Combination Figure 16 As shown, in some optional embodiments, the rotating part 200 has a set tilt angle on one side facing the center of the annular air passage 100. This creates an angle between the direction of the airflow ejected from the jet nozzle 201 on the rotating part 200 and the direction of the air conditioning airflow flowing through the inner annular surface 102 of the annular air passage 100. This causes the airflow ejected from the jet nozzle 201 to deflect the air conditioning airflow flowing through the inner annular surface 102 of the annular air passage 100, thus providing the air conditioner with various air outlet modes to meet diverse needs.

[0068] Optionally, the tilt angle refers to the tilt angle between the side of the rotating part 200 facing the center of the annular air duct 100 and the horizontal direction. This creates an angle between the direction of the airflow ejected from the jet nozzle 201 on the rotating part 200 and the direction of the air conditioning airflow flowing through the inner annular surface 102 of the annular air duct 100. Consequently, the airflow ejected from the jet nozzle 201 causes the air conditioning airflow flowing through the inner annular surface 102 of the annular air duct 100 to deflect, giving the air conditioner a variety of air outlet modes to meet diverse needs.

[0069] like Figure 16 As shown, b is the tilt angle between the side of the rotating part 200 facing the center of the annular airway 100 and the horizontal direction.

[0070] Optionally, the tilt angle is greater than or equal to 10 degrees and less than or equal to 60 degrees. When the tilt angle is less than 10 degrees, the angle between the side of the rotating part 200 facing the center of the annular air passage 100 and the horizontal direction is small. This results in a larger angle between the airflow direction ejected from the jet nozzle 201 on the rotating part 200 and the airflow flowing out from the inner annular surface 102 of the annular air passage 100. The contact of these two airflows causes a significant pressure loss, affecting the intensity of the exhaust air. When the tilt angle is greater than 60 degrees, the angle between the side of the rotating part 200 facing the center of the annular air passage 100 and the horizontal direction is large. This results in a larger angle between the jet nozzle 201 on the rotating part 200 and the horizontal direction. The angle between the airflow direction ejected at nozzle 201 and the airflow flowing out from the inner annular surface 102 of the annular air passage 100 is small. This makes it difficult for the airflow ejected at nozzle 201 to deflect the air conditioning airflow flowing through the inner annular surface 102 of the annular air passage 100. Therefore, when the tilt angle is greater than or equal to 10 degrees and less than or equal to 60 degrees, the airflow ejected at nozzle 201 can better deflect the air conditioning airflow flowing through the inner annular surface 102 of the annular air passage 100, and the airflow pressure loss is small. This allows the air conditioner to have a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0071] Optionally, the tilt angle is 45 degrees. This allows the airflow at the jet nozzle 201 to effectively deflect the air conditioning airflow flowing through the inner annular surface 102 of the annular air passage 100, while minimizing airflow pressure loss. This improves the diversity of airflow output and reduces airflow pressure loss.

[0072] Combination Figure 17 As shown, in some optional embodiments, the jet device further includes a drive device 700. The drive device 700 is connected to the rotating part 200 and is configured to drive the rotating part 200 to rotate. Thus, by driving the rotating part 200 to rotate via the drive device 700, the rotating part 200 can rotate smoothly, and the jet outlet 201 disposed 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.

[0073] Optionally, the drive device 700 includes a ring gear 701 and a motor 702. The ring gear 701 is arranged around the rotating part 200; the motor 702 has a gear at its output end, which meshes with the ring gear 701. In this way, the gear at the output end of the motor 702 drives the ring gear 701 to rotate, thereby driving the rotating part 200 to rotate. Due to the stable transmission between the gear and the ring gear 701, the jet port 201 provided 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.

[0074] Optionally, the motor 702 is fixed by a motor bracket 703, and the motor bracket 703 is connected to the annular air passage 100. In this way, fixing the motor 702 by the motor bracket 703 and connecting the motor 702 to the annular air passage 100 enhances the stability of the motor 702.

[0075] Optionally, the motor 702 has three speed settings: low, medium, and high.
