Description

Technical Field

[0001] This application relates to the field of jet air supply technology, and in particular to a jet air outlet device. Background Technology

[0002] As people's living standards improve, air conditioners are widely used in people's daily lives, and there are also diverse demands for the air supply of air conditioners. When using air conditioners to cool or heat the room, users tend to prefer air conditioners that can supply air to the room evenly and comfortably.

[0003] Some related technologies involve setting up an air outlet channel with an air outlet end and a guide end on the air conditioner. During the air outlet process, a negative pressure is generated inside the air outlet channel, thereby introducing indoor air at the guide end and mixing it with the hot and cold air blown out from the air outlet end. A guide structure is set up in the air outlet channel to make the air outlet more uniform and comfortable, so as to meet the user's air supply needs of the air conditioner. However, the negative pressure generated in the air outlet channel in the related technologies is relatively small, the guide effect is poor, and the uniformity of air outlet is poor, and the air supply distance is short.

[0004] Therefore, how to improve the uniformity of airflow and the air delivery distance, and improve the diversion effect, has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a jet air outlet device to improve the uniformity of the airflow and the air delivery distance, enhance the diversion effect, and thus improve the comfort of the air delivery.

[0007] In some embodiments, the jet air outlet device includes an air outlet duct and a guide vane. The inner wall of the air outlet duct defines an airflow channel, and one end of the air outlet duct is an air outlet, and the other end is a flow inlet. A first air inlet and a second air inlet are provided on the inner wall of the air outlet duct. The second air inlet is located in front of the first air inlet along the airflow channel. A rotatable guide member is provided in the airflow channel at the position corresponding to the first air inlet and the second air inlet. The guide member is annular, and the outer annular surface of the guide member and the inner wall of the air outlet duct define a jet outlet facing the air outlet. The guide vane is disposed on the outer annular surface of the guide member and extends from one end to the other along the axial direction of the guide member. The guide vane is a spiral structure with an offset angle relative to the axial direction of the guide member.

[0008] The jet exhaust device provided in this embodiment can achieve the following technical effects:

[0009] The heat exchange airflow enters the airflow channel through the first and second air inlets located on the inner wall of the air outlet. The incoming airflow is deflected by the guide vanes and the spiral structure on the outer ring of the guide vanes, causing the guide vanes to rotate within the airflow channel. This forms a spiral airflow that blows from the jet outlet to the outlet, improving the uniformity of the airflow. Furthermore, since the second air inlet is located in front of the first air inlet, the airflow from the first air inlet, after being guided, can push the airflow from the second air inlet, increasing the pressure of the outlet airflow and increasing the delivery distance. Moreover, the spiral jet outlet can create a strong negative pressure area within the airflow channel, allowing the indoor airflow near the inlet to enter the airflow channel more efficiently under the action of negative pressure, mix with the heat exchange airflow, and be blown out, improving the inlet effect. In addition, the airflow blown out from the jet outlet defined by the annular guide vanes and the inner wall of the airflow channel can surround the airflow introduced by the inlet, enhancing the mixing effect of the indoor airflow and the heat exchange airflow, further improving the comfort of the airflow.

[0035] Combination Figure 1-5As shown, in some embodiments, a jet air outlet device includes: an air outlet duct 100 and a guide vane 201. The inner wall of the air outlet duct 100 defines an airflow channel 110. One end of the air outlet duct 100 is an air outlet 101, and the other end is a flow inlet 102. The inner wall of the air outlet duct 100 is provided with a first air inlet 111 and a second air inlet 112. The second air inlet 112 is located in front of the first air inlet 111 along the airflow direction of the airflow channel 110. Rotatable guide members 200 are provided in the airflow channel 110 at positions corresponding to the first air inlet 111 and the second air inlet 112. The guide members 200 are annular, and the outer annular surface of the guide members 200 and the inner wall of the air outlet duct 100 define a jet outlet 202 facing the air outlet 101. The guide vane 201 is disposed on the outer annular surface of the guide member 200 and extends from one end of the guide member 200 along the axial direction to the other end. The guide vane 201 is a spiral structure with an offset angle relative to the axial direction of the guide member 200.

[0036] Using the jet air outlet device provided in this embodiment, the heat exchange airflow enters the airflow channel 110 through the first air inlet 111 and the second air inlet 112 disposed on the inner side wall of the air outlet duct 100. The incoming airflow is deflected under the guidance of the guide member 200 and the guide vane 201 with a spiral structure located on the outer ring surface of the guide member 200, causing the guide member 200 to rotate within the airflow channel 110. This forms a spiral airflow that blows from the jet outlet 202 towards the air outlet 101, improving the uniformity of the airflow. Furthermore, since the second air inlet 112 is located in front of the first air inlet 111, the incoming airflow from the first air inlet 111 is guided to... The spiral jet exhaust creates a pushing effect on the incoming airflow at the second air inlet 112, increasing the pressure of the outgoing airflow and improving the air delivery distance. Furthermore, the spiral jet exhaust can create a strong negative pressure area within the airflow channel 110, allowing the indoor airflow near the inlet 102 to enter the airflow channel 110 more efficiently under the action of negative pressure, mix with the heat exchange airflow, and be blown out, thus improving the airflow extraction effect. Moreover, the airflow blown out by the annular guide 200 and the jet outlet 202 defined by the inner sidewall of the airflow channel 110 can surround the airflow introduced by the inlet 102, enhancing the mixing effect of the indoor airflow and the heat exchange airflow, and further improving the comfort of the exhaust airflow.

[0037] Optionally, the flow surface of the airflow channel 110 is circular, and the first air inlet 111 and the second air inlet 112, which are located on the inner wall of the air outlet duct 100, are both annular. In this way, the airflow channel 110 is a cylindrical flow channel as a whole, and the airflow can flow smoothly within the airflow channel 110. The annular first air inlet 111 and the second air inlet 112, located on the inner wall of the airflow channel 110, can blow annular incoming airflow into the airflow channel 110. Since the guide members 200 located at the first air inlet 111 and the second air inlet 112 are both annular, the airflow blown in by the first air inlet 111 and the second air inlet 112 can be blown more evenly on the outer annular surface of the guide member 200. After being guided by the guide member 200, a more uniform airflow can be formed. Moreover, the annular incoming airflow can better act on the guide member 200 to make it rotate, forming a more uniform spiral airflow.

[0038] Optionally, the guide member 200 is a trumpet-shaped structure with its outer surface curved towards its central axis. The outer ring surface of the guide member 200 is the outer surface of the trumpet-shaped structure, and the inner ring surface is the inner surface of the trumpet-shaped structure. In this way, the outer surface of the trumpet-shaped guide member 200 and the inner wall of the airflow channel 110 define an annular jet port 202. The heat exchange airflow blown onto the outer ring surface of the guide member 200 through the first air inlet 111 and the second air inlet 112 can be better guided by the guide member 200. The guided airflow can be blown out more evenly through the annular jet port 202, improving the comfort of air supply.

[0039] Understandably, guide members 200 are provided at the corresponding positions of the first air inlet 111 and the second air inlet 112 in the airflow channel 110. The outer ring surface of the guide member 200 at the first air inlet 111 and the inner wall of the airflow channel 110 at the first air inlet 111 define an outlet 202. The outer ring surface of the guide member 200 at the second air inlet 112 and the inner wall of the airflow channel 110 at the second air inlet 112 also define an outlet 202. That is, there is an outlet 202 at both the first air inlet 111 and the second air inlet 112.

[0040] Optionally, the central axis of the guide member 200 coincides with the central axis of the airflow channel 110. Thus, since the flow surface of the airflow channel 110 is circular, the airflow channel 110 is a circular airflow channel 110. The central axis of the guide member 200 coincides with the central axis of the airflow channel 110, making the guide member 200 and the airflow channel 110 concentric. This results in the jet port 202, defined by the guide member 200 and the inner wall of the airflow channel 110, having a uniform annular shape. This allows the airflow flowing into the airflow channel 110 from the first air inlet 111 and the second air inlet 112 to be guided more evenly by the guide member 200, and the guided heat exchange airflow to be ejected more evenly through the jet port 202.

[0041] Optionally, the guide member 200 includes a wide opening 203 and a narrow opening 204, with the narrow opening 204 of the guide member 200 facing the air outlet 101 of the airflow channel 110 along its axial direction. In this way, since the guide member 200 is a trumpet-shaped structure with its outer surface bent towards its central axis, facing its narrow opening 204 towards the air outlet 101 of the airflow channel 110 allows the airflow guided by the guide member 200 to be blown out along the jet opening 202 more effectively.

[0042] Optionally, the guide vane 201 is located on the outer ring surface of the trumpet-shaped guide member 200, and extends along the edge of its wide opening 203 to the edge of its narrow opening 204. In this way, the heat exchange airflow blowing on the outer ring surface of the guide member 200 can be better guided and deflected by the guide vane 201, and at the same time, the deflection pressure can be applied to the guide vane 201, causing the guide member 200 to rotate, better forming a spiral airflow, improving the uniformity of the airflow, and the spiral airflow can form a strong negative pressure area behind it, which can better introduce indoor air through the inlet 102 to mix with the heat exchange airflow, improving the comfort of the airflow.

[0043] Optionally, along the direction from the wide opening 203 to the narrow opening 204 of the guide vane 200, the height of the guide vane 201 gradually increases first and then gradually decreases. This makes the guide vane 201 narrower at both ends and wider in the middle at the edges of the wide opening 203 and narrow opening 204, so that the heat exchange airflow blowing onto the outer annular surface of the guide vane 200 through the air inlet can be diverted at its narrower ends when it encounters the obstruction of the guide vane 201, reducing airflow pressure loss.

[0044] Understandably, the height of the guide vane 201 refers to the height by which the guide vane 201 protrudes outward along the outer ring surface of the guide member 200.

[0045] Optionally, the axial offset angle of the guide vane 201 relative to the guide member 200 means that the line connecting the end of the guide vane 201 located at the wide opening 203 and the end located at the narrow opening 204 in the top view has an offset angle with the axis of the guide member 200. In this way, since the airflow blowing onto the guide member 200 through the first air inlet 111 and the second air inlet 112 is blown in radially along the guide member 200, the line connecting the end of the guide vane 201 at the wide opening 203 and the end at the narrow opening 204 has an offset angle with the axis of the guide member 200. The airflow direction can be changed by the guide vane 201, so that the airflow is deflected and blown out from the jet port 202, thereby forming a spiral airflow, improving the uniformity of airflow and the air delivery distance. Moreover, the spiral airflow can form a strong negative pressure area behind it, which can better introduce indoor air and mix it with the heat exchange airflow through the inlet 102, improving the comfort of the airflow.

[0046] like Figure 4 As shown, angle a is the offset angle.

[0047] Optionally, multiple guide vanes 201 are provided and evenly distributed on the outer ring surface of the guide member 200. Since the guide member 200 is annular, the heat exchange airflow blown into the airflow channel 110 can be evenly blown onto the outer ring surface of the guide member 200. The outer ring surface of the guide member 200 is the air-receiving surface; therefore, providing multiple evenly distributed guide vanes 201 on the outer ring surface of the guide member 200 can more evenly guide the heat exchange airflow, causing it to deflect. Furthermore, since the guide vanes 201 are subjected to pressure from the heat exchange airflow when guiding it, driving the guide member 200 to rotate, providing multiple evenly distributed guide vanes 201 ensures even force distribution and more stable rotation of the guide member 200, thereby better forming a spiral airflow and improving the uniformity of the airflow. Moreover, the spiral airflow can create a strong negative pressure area behind it, better introducing indoor air through the inlet 102 to mix with the heat exchange airflow, improving the comfort of the airflow.

[0048] Optionally, multiple guide elements 200 are provided in the airflow channel 110 at positions corresponding to the first air inlet 111 and the second air inlet 112, and the centers of the multiple guide elements 200 are all on the same axis, evenly arranged in the airflow channel 110 along the axial direction of the air outlet duct 100, defining an annular flow channel 205 between adjacent guide elements 200. In this way, by providing multiple guide elements 200 evenly arranged in the airflow channel 110 along the axial direction of the air outlet duct 100 at both the first air inlet 111 and the second air inlet 112, the heat exchange airflow entering the airflow channel 110 through the first air inlet 111 and the second air inlet 112 can be better guided and blown out. The guidance by multiple guide elements 200 can form a stronger spiral airflow, further improving the air delivery distance and airflow uniformity. Furthermore, because the guide element 200 at the front of the adjacent guide elements 200... The inner annular surface at the large opening 203 will have a certain guiding effect on the airflow of the rear guide 200, causing the airflow blown out through the annular flow channel 205 to have an axial offset, so that the airflow blown out through the annular flow channel 205 can be blown more concentratedly towards the air outlet 101 of the airflow channel 110, forming a stronger spiral airflow, further increasing the air delivery distance, and forming a stronger negative pressure area behind the airflow channel 110, which can better introduce indoor air and heat exchange airflow through the inlet 102 for mixing, thereby improving the comfort of the airflow.

[0049] Optionally, an annular flow channel 205 is defined between adjacent guide members 200, between the edge of the narrow opening 204 of the rear guide member 200 and the inner annular surface of the wide opening 203 of the front guide member 200. In this way, when the airflow is guided by multiple guide members 200, the airflow blown out through the annular flow channel 205 can be guided by the inner annular surface corresponding to the wide opening 203 of the front guide member 200, causing the airflow blown out through the annular flow channel 205 to be deflected axially upwards towards the guide member 200, thereby making the airflow more concentrated and blown towards the air outlet 101 of the airflow channel 110, converging into a stronger spiral airflow and further increasing the air delivery distance.

[0050] Understandably, multiple guide elements 200 are provided at both the first air inlet 111 and the second air inlet 112. The annular flow channel 205 refers to the flow channel defined between adjacent guide elements 200 among the multiple guide elements 200 provided at the first air inlet 111, and the flow channel defined between adjacent guide elements 200 among the multiple guide elements 200 provided at the second air inlet 112.

[0051] Optionally, the guide vanes 201 on the outer ring surface of adjacent guide elements 200 are on the same spiral trajectory. In this way, when the air is guided by multiple evenly arranged guide elements 200, the spiral airflow blown out after being guided by each guide element 200 can be better converged, avoiding mutual interference between the airflow blown out after being guided by different guide elements 200, reducing the pressure loss of the outlet airflow, so that the airflow blown out through the annular flow channel 205 can be blown more concentratedly towards the air outlet 101 of the airflow channel 110, forming a stronger spiral outlet airflow, further increasing the air delivery distance, forming a stronger negative pressure area behind the airflow channel 110, and better introducing indoor air and heat exchange airflow through the inlet 102 for mixing, improving the comfort of the outlet airflow.

[0052] Optionally, the guide vanes 201 on the outer ring surface of the multiple guide elements 200 corresponding to the first air inlet 111 and the guide vanes 201 on the outer ring surface of the multiple guide elements 200 corresponding to the second air inlet 112 are all on the same spiral trajectory. In this way, the airflow guided by the guide element 200 at the first air inlet 111 can better converge with the airflow guided by the guide element 200 at the second air inlet 112, avoiding mutual interference between the airflow at the first air inlet 111 and the airflow at the second air inlet 112. This allows the airflow at the first air inlet 111 to better push the airflow at the second air inlet 112, increasing the pressure of the airflow in the airflow channel 110, further increasing the air delivery distance, and forming a stronger negative pressure area behind the airflow channel 110. This allows for better mixing of indoor air and heat exchange airflow through the inlet 102, improving the comfort of the airflow.

[0053] Understandably, a spiral trajectory refers to the helix of a spiral object.

[0054] Optionally, the multiple guide elements 200 provided at the first air inlet 111 and the second air inlet 112 are all connected by a spiral connecting frame 206. In this way, the spiral connecting frame 206 connects the multiple guide elements 200 at the first air inlet 111 and the second air inlet 112 into a whole, allowing the multiple guide elements 200 to rotate synchronously under the action of the incoming airflow. The spiral connecting frame 206 also guides the incoming airflow and reduces interference with the spiral airflow, allowing the incoming airflow to be better guided by the guide elements 200 to form a spiral airflow, resulting in a more uniform spiral airflow and further improving air delivery comfort.

[0055] Optionally, the spiral trajectory of the spiral connector 206 is the same as the spiral trajectory of the guide vane 201 on the outer ring surface of the adjacent guide member 200. This further enhances the guiding effect of the spiral connector 206 and better reduces the interference of the spiral connector 206 on the spiral airflow, allowing the inlet airflow to be better guided by the guide member 200 to form a spiral outlet airflow.

[0056] Optionally, multiple spiral connecting brackets 206 are provided, and the multiple spiral connecting brackets 206 are evenly distributed along the outer periphery of the guide member 200. In this way, a more stable connection can be made between the multiple annular guide members 200, and a better guiding effect can be achieved for the air intake.

[0057] Combination Figure 6-8 As shown, in some optional embodiments, the jet air outlet device further includes: a first air inlet channel 300 and a second air inlet channel 400. One end of the first air inlet channel 300 is sleeved on the outer wall of the air outlet 100 corresponding to the first air inlet 111 and communicates with the first air inlet 111; one end of the second air inlet channel 400 is sleeved on the outer wall of the air outlet 100 corresponding to the second air inlet 112 and communicates with the second air inlet 112. In this way, heat exchange airflow is delivered to the first air inlet 111 through the first air inlet channel 300 and to the second air inlet 112 through the second air inlet channel 400. Moreover, the first air inlet channel 300 and the second air inlet channel 400 are respectively fitted on the outside of the airflow channel 110, thereby better forming annular air intake at the first air inlet 111 and the second air inlet 112, improving the uniformity of air intake at the first air inlet 111 and the second air inlet 112. The more uniform air intake airflow can form a more uniform air outlet under the guidance of the guide member 200. The airflow blown into the ground through the annular first air inlet 111 can better act on the airflow blown into the second air inlet 112, increasing the pressure in the airflow channel 110 and increasing the air delivery distance.

[0058] Optionally, both the first air inlet channel 300 and the second air inlet channel 400 are arranged perpendicular to the axial direction of the airflow channel 110. Since both the first air inlet 111 and the second air inlet 112 are annular and the airflow direction is radial along the airflow channel 110, arranging the first air inlet channel 300 and the second air inlet channel 400 perpendicular to the axial direction of the airflow channel 110 allows the incoming airflow within the first air inlet channel 300 and the second air inlet channel 400 to enter the first air inlet 111 and the second air inlet 112 more smoothly, reducing the pressure loss of the incoming airflow and increasing the air delivery distance.

[0059] Optionally, the first air inlet channel 300 includes a first direct current section 310 and a first return current section 320. The first direct current section 310 is disposed on one side of the air outlet duct 100 and partially communicates with the first air inlet 111; the first return current section 320 communicates with the first direct current section 310 and is disposed on the other side of the air outlet duct 100, communicating with the remaining portion of the first air inlet 111. In this way, the incoming airflow flows towards the first air inlet 111 through the first direct current section 310. Upon reaching the first air inlet 111, part of the incoming airflow can directly enter the first air inlet 111, while the remainder flows into the first return current section 320. Then, under the guidance of the first return current section 320, the flow direction changes and flows into the first air inlet 111, enabling the annular first air inlet 111 to receive air evenly. Moreover, the guidance of the first return current section 320 reduces the pressure loss of the incoming airflow at the first air inlet 111, improving the air intake effect of the first air inlet 111 and thus improving the air outlet effect.

[0060] Optionally, the first direct current section 310 is located on one side of a vertical line passing through the center of the first air inlet 111, and the first return flow section 320 is located on the other side of the vertical line passing through the center of the first air inlet 111. The first direct current section 310 and the first return flow section 320 together define the first air inlet 111 on the outer wall of the airflow channel 110. In this way, the first return flow section 320 and the first direct current section 310 are better connected, and the airflow flowing in the first direct current section 310 can smoothly enter the first return flow section 320, and then enter the first air inlet 111 under the guidance of the first return flow section 320, thereby reducing the loss of airflow pressure.

[0061] Optionally, the first return flow section 320 is a semi-annular flow channel 205 surrounding the air outlet duct 100. This allows for better guidance of the incoming airflow, enabling the airflow flowing into the first return flow section 320 from the first direct flow section 310 to enter the first air inlet 111 more effectively under the guidance of the annular inner wall of the first return flow section 320, thereby reducing the pressure loss of the incoming airflow.

[0062] Optionally, the diameter of the outer annular surface of the first return flow section 320 is the same as the height of the first direct flow section 310. This allows the intake airflow flowing in the first direct flow section 310 to flow smoothly into the first return flow section 320, reducing the pressure loss of the intake airflow.

[0063] Optionally, the second air inlet channel 400 includes a second direct current section 410 and a second return current section 420. The second direct current section 410 is disposed on one side of the airflow channel 110 and partially communicates with the second air inlet 112; the second return current section 420 flows through the second direct current section 410 and is disposed on the other side of the airflow channel 110, communicating with the remaining portion of the second air inlet 112. In this way, the incoming airflow flows towards the second air inlet 112 through the second direct current section 410. At the position of reaching the second air inlet 112, part of the incoming airflow can directly enter the second air inlet 112, while the rest flows into the second return current section 420. Then, under the guidance of the second return current section 420, the flow direction changes and flows into the second air inlet 112, so that the annular second air inlet 112 can receive air evenly. Moreover, the guidance of the second return current section 420 reduces the pressure loss of the incoming airflow at the second air inlet 112, improving the air intake effect of the second air inlet 112 and thus improving the air outlet effect.

[0064] Optionally, the second direct current section 410 is located on one side of a vertical line passing through the center of the second air inlet 112, and the second return flow section 420 is located on the other side of a vertical line passing through the center of the second air inlet 112. The second direct current section 410 and the second return flow section 420 together define the second air inlet 112 on the outer wall of the airflow channel 110. This allows for better communication between the second return flow section 420 and the second direct current section 410, enabling the airflow flowing in the second direct current section 410 to smoothly enter the second return flow section 420, and then, guided by the second return flow section 420, enter the second air inlet 112, reducing the loss of airflow pressure.

[0065] Optionally, the second return flow section 420 is also a semi-annular flow channel 205 surrounding the airflow channel 110. This allows for better guidance of the incoming airflow, enabling the airflow flowing into the second return flow section 420 through the second direct flow section 410 to enter the second air inlet 112 more effectively under the guidance of the annular inner wall of the second return flow section 420, thereby reducing the pressure loss of the incoming airflow.

[0066] Optionally, the diameter of the outer annular surface of the second return section 420 is the same as the height of the second direct flow section 410. This allows the intake airflow flowing in the second direct flow section 410 to flow smoothly into the second return section 420, reducing the pressure loss of the intake airflow.

[0067] Understandably, the height of the first DC section 310 refers to the distance between the lower end face and the upper end face of the first DC section 310 in the vertical direction; the height of the second DC section 410 refers to the distance between the lower end face and the upper end face of the second DC section 410 in the vertical direction.

[0068] Optionally, along the horizontal direction, the first direct current section 310 of the first air inlet channel 300 is located on one side of the airflow channel 110, and the second direct current section 410 of the second air inlet channel 400 is located on the other side of the airflow channel 110. This facilitates the arrangement of the first air inlet channel 300 and the second air inlet channel 400, and makes reasonable use of space.

[0069] Combination Figure 9-12 As shown, in some optional embodiments, the jet exhaust device further includes an annular mounting groove and a support mechanism. The annular mounting groove is disposed through the outer wall of the exhaust duct 100 and is located between the first air inlet 111 and the second air inlet 112. The support mechanism passes through the annular mounting groove and is connected to the guide members 200 at the first air inlet 111 and the second air inlet 112. Thus, with the annular mounting groove through the outer wall of the exhaust duct 100, and the support mechanism passing through the annular mounting groove to connect with the guide members 200 at the first air inlet 111 and the second air inlet 112, the connection position of the support mechanism is located in the middle of the first air inlet 111 and the second air inlet 112, thereby providing more stable support for the guide members 200 at the first air inlet 111 and the second air inlet 112, and improving the stability of the guide members 200 when rotating.

[0070] Optionally, the support mechanism includes an annular bushing 500 and an annular support bracket 600. The annular bushing 500 is fixedly installed in the annular mounting groove; the annular support bracket 600 is rotatably disposed within the annular bushing 500, and its inner annular surface passes through the annular bushing 500 and connects to the guide member 200 disposed at the first air inlet 111 and the second air inlet 112. In this way, a fixed annular bushing 500 is set in the annular mounting groove, and an annular support shaft 600 is rotatably set in the annular bushing 500. The inner annular surface of the annular support shaft 600 passes through the annular bushing 500 and connects to the guide members 200 at the first air inlet 111 and the second air inlet 112. When the guide members 200 at the first air inlet 111 and the second air inlet 112 rotate under the action of the incoming airflow, the annular support shaft 600 can support the guide members 200 and rotate relative to the annular bushing 500. Since the inner annular surface of the annular support shaft 600 is connected to the guide members 200, it forms a stable support for the guide members 200. When the guide members 200 are driven to rotate by the incoming airflow, the force on the guide members 200 is more uniform, and they can be driven more stably by the incoming airflow, thereby better forming a spiral airflow and improving the stability of the airflow.

[0071] Optionally, the inner ring surface of the annular support shaft bracket 600 is connected to the guide members 200 at the first air inlet 111 and the second air inlet 112 via a spiral connecting frame 206. Thus, since the guide members 200 at the first air inlet 111 and the second air inlet 112 are connected by the spiral connecting frame 206, connecting the inner ring surface of the annular support shaft bracket 600 to the spiral connecting frame 206 provides better support for the guide members 200 at the first air inlet 111 and the second air inlet 112.

[0072] Optionally, the inner ring surface of the annular support shaft 600 is connected to the middle position of multiple spiral connecting frames 206 along the axial direction of the air outlet 100. This improves the support stability of the guide members 200 at the first air inlet 111 and the second air inlet 112, making the force on the guide members 200 at the first air inlet 111 and the second air inlet 112 more balanced.

[0073] Optionally, the annular bushing 500 is a hollow annular structure with annular openings on both its inner and outer annular surfaces. An annular support shaft bracket 600 passes through the annular bushing 500, with its inner annular surface passing through the opening on the inner annular surface of the annular bushing 500 and connecting to the spiral connecting frame 206. The outer annular surface of the annular support shaft bracket 600 extends beyond the opening on the outer annular surface of the annular bushing 500. This allows the annular support shaft bracket 600 to rotate more stably within the annular bushing 500 and enhances its support stability for the guide member 200. Furthermore, the extension of the outer annular surface of the annular support shaft bracket 600 from the opening on the outer annular surface of the annular bushing 500 facilitates driving the annular support shaft bracket 600.

[0074] Optionally, a braking assembly 510 is provided on the side wall corresponding to the outer ring surface of the annular bushing 500. In this way, the braking assembly 510 can brake the rotating annular support shaft 600, reduce the rotational speed of the annular support shaft 600, and thus reduce the rotational speed of the guide member 200.

[0075] Optionally, the braking assembly 510 includes a clamping frame 511 and a brake friction pad 512. The clamping frame 511 has a first arm and a second arm. The first arm is located on one side wall corresponding to the outer ring surface of the annular bushing 500, and the second arm is located on the other side wall corresponding to the outer ring surface of the annular bushing 500. The first arm and the second arm are connected by a screw 513, which can adjust the distance between the first arm and the second arm. Two brake friction pads 512 are provided, one of which is located on the first arm and the other is located on the second arm. In this way, by setting clamping frames 511 on the two axially upward side walls of the annular bushing 500, and using the rotation of the screw 513 to adjust the distance between the first arm and the second arm, the clamping degree of the clamping frames 511 can be adjusted. When it is necessary to brake the annular support shaft frame 600, the rotation of the screw 513 shortens the distance between the first arm and the second arm of the clamping frame 511, so that the brake friction plates 512 set on the first arm and the second arm come into contact with the two axially upward side walls of the annular support shaft frame 600 and rub against each other, thereby reducing the rotational speed of the annular support shaft frame 600. Moreover, by applying friction braking to both sides of the annular support shaft frame 600, the braking friction force on the annular support shaft frame 600 is more balanced, and the braking of the annular support shaft frame 600 is more stable.

[0076] Optionally, the braking assembly 510 further includes a brake motor 514. The brake motor 514 is disposed on the outer wall of the air outlet duct 100, and the output end of the brake motor 514 is connected to the screw 513, which can drive the screw 513 to rotate. In this way, by rotating the motor, the screw 513 can be driven to rotate, thereby adjusting the tightness of the clamping frame 511 in the braking assembly 510, and better braking and decelerating the annular support shaft frame 600.

[0077] Optionally, the annular support shaft bracket 600 is provided with rolling balls 610 on both sides along its axial direction, and the annular bushing 500 is provided with annular rolling grooves 520 on both inner walls along its axial direction corresponding to the positions of the rolling balls 610. The rolling balls 610 are confined to roll within the annular rolling grooves 520. In this way, by utilizing the rolling balls 610 on both sides of the annular support shaft bracket 600 along its axial direction to roll within the annular rolling grooves 520 on both inner walls of the annular bushing 500 along its axial direction, the friction between the annular support shaft bracket 600 and the annular bushing 500 is further reduced, the efficiency of mechanical power transmission is improved, and the guide member 200 can be driven by the intake airflow more efficiently, reducing the pressure loss of the intake airflow, better forming a spiral exhaust airflow, and improving the uniformity of the exhaust airflow and the delivery distance.

[0078] Optionally, the annular support shaft bracket 600 has ball grooves on both sides along its axial direction, and the rolling balls 610 are rotatably disposed in the ball grooves. In this way, the rolling balls 610 are not easy to fall out during rotation, further improving the stability of the annular support shaft bracket 600 when rotating relative to the annular bushing 500, and thus improving the stability of the guide member 200 when rotating.

[0079] Optionally, the annular support shaft bracket 600 has multiple rolling balls 610 on both sides along its axial direction, and the multiple rolling balls 610 on one side of the annular support shaft bracket 600 are evenly arranged in a ring corresponding to the annular rolling groove 520. In this way, by providing multiple rolling balls 610 evenly distributed in a ring on both sides of the annular support shaft bracket 600, the stability of the annular support shaft bracket 600 can be further improved, allowing the annular support shaft bracket 600 to rotate better.

[0080] Optionally, the jet air outlet structure further includes a drive device 700. The drive device 700 is disposed on the outer wall of the air outlet duct 100, and its output end is meshed with the outer ring surface of the annular support shaft 600. In this way, the drive device 700 can actively drive the annular support shaft 600 to rotate, thereby actively driving the guide member 200 to rotate. The rotation speed of the guide member 200 can be adjusted by adjusting the rotation speed of the output end of the drive device 700, so that the guide member 200 can not only be driven by the incoming airflow, but also be actively driven to rotate by the drive device 700 when the incoming airflow pressure is low, so as to better guide the incoming airflow to form a spiral air outlet, reduce the dependence on the incoming airflow, and when the incoming airflow is low, the rotating guide member 200 can also form a negative pressure at the first air inlet 111 and the second air inlet 112, actively drawing the airflow in the first air inlet channel 300 and the second air inlet channel 400 to form a spiral air outlet, thus meeting the user's personalized needs.

[0081] Optionally, the drive device 700 is a drive motor, which is fixedly mounted on the outer wall of the air outlet duct 100 via a motor mount, and its output end meshes with the outer ring surface of the annular support shaft 600. In this way, the drive motor can effectively drive the annular support shaft 600 to rotate, thereby driving the guide component 200 to rotate, and the drive method using a drive motor is relatively low in cost.

[0082] Combination Figure 13-15 As shown, in some optional embodiments, the jet air outlet device further includes a housing 800. The housing 800 has a front panel 810 and a rear panel 820. The air outlet duct 100, the first air inlet channel 300, and the second air inlet channel 400 are all disposed within the housing 800, with the air outlet 100 penetrating through the housing 800. The air outlet 101 is located on the front panel 810, and the air inlet 102 is located on the rear panel 820. In this way, the airflow from the first air inlet channel 300 and the second air inlet channel 400 is guided by the guide member 200 to form a spiral airflow. This airflow is then blown out through the air outlet 101 located on the front panel 810, creating a strong negative pressure area within the airflow channel 110. This allows the indoor airflow near the air inlet 102 to enter the airflow channel 110 more efficiently under the action of negative pressure, mix with the heat exchange airflow, and then be blown out, thus improving the airflow effect.

[0083] Optionally, the housing 800 also includes a first heat exchange chamber 830 and a second heat exchange chamber 840. The first heat exchange chamber 830 is connected to the air inlet end of the first air inlet channel 300, and the second heat exchange chamber 840 is connected to the air inlet end of the second air inlet channel 400. Both the first heat exchange chamber 830 and the second heat exchange chamber 840 are equipped with heat exchangers and fans. In this way, indoor air can flow into the first heat exchange chamber 830 and the second heat exchange chamber 840 for heat exchange. The heat-exchanged airflow flows into the airflow channel 110 through the first air inlet channel 300 and the second air inlet channel 400, and forms a spiral airflow under the action of the guide member 200, thereby improving the uniformity and comfort of the airflow.

[0084] Optionally, the outer wall of the casing 800 is provided with a first return air inlet 850 and a second return air inlet 860. The first return air inlet 850 communicates with the first heat exchange chamber 830, and the second return air inlet 860 communicates with the second heat exchange chamber 840. In this way, indoor air enters the first heat exchange chamber 830 and the second heat exchange chamber 840 through the first return air inlet 850 and the second return air inlet 860 respectively, exchanges heat with the heat exchanger, and is then blown into the airflow channel 110. Under the action of the guide member 200, a spiral airflow is formed, which improves the uniformity and comfort of the airflow.

[0085] Understandably, this jet air outlet device could be an air conditioner.
