The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0027] Unless otherwise stated, the term "multiple" means two or more.

[0028] In this embodiment of the disclosure, the character " / " represents the symbol for division in a mathematical formula.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] Combination Figure 1-6As shown, this embodiment of the present disclosure provides a jet device, including: a jet channel 100, a rotating part 200, and a jet port 300. The jet channel 100 is connected to a jet fan 101; the rotating part 200 is rotatably connected to one end of the jet channel 100 and closes that end; the jet port 300 is disposed on the rotating part 200.

[0031] Using the jet device provided in this embodiment, the rotating part 200 blocks one end of the jet channel 100, and the rotating part 200 is provided with a jet port 300. It can rotate with the rotating part 200, so that the airflow in the jet channel 100 flows out through the jet port 300. The direction of the jet changes with the rotation of the rotating part 200, which in turn drives the overall air outlet of the air conditioner to change, so that the air conditioner has a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0032] Optionally, the jet channel 100 includes a cylindrical channel 102 and a conical channel 103. The larger diameter end of the conical channel 103 is connected to the cylindrical channel 102, and the smaller diameter end of the conical channel 103 faces the rotating part 200. In this way, the jet channel 100 is divided into a cylindrical channel 102 and a conical channel 103. The cylindrical channel 102 provides a larger flow area for the airflow, increasing the airflow rate and making the airflow distribution more uniform, thereby ensuring the stability of the airflow. The conical channel 103 is structurally more compatible with the installation structure of the rotating part 200, allowing for a seamless connection between the conical channel 103 and the rotating part 200, preventing airflow loss. Furthermore, as the airflow moves from the cylindrical channel 102 to the conical channel 103, the reduced flow area creates a funnel effect, increasing the airflow velocity and allowing the airflow to quickly reach the rotating part 200, thus increasing the jet speed.

[0033] It is worth noting that the funnel effect refers to the phenomenon that when fluid moves from a section of a pipe with a larger cross-sectional area to a section with a smaller cross-sectional area, the fluid velocity increases, similar to the phenomenon of water flowing through a funnel.

[0034] Optionally, the cylindrical channel 102 and the conical channel 103 are integrally formed. This integrally formed structure is more stable, making it less likely for the cylindrical channel 102 and the conical channel 103 to shift in position, preventing airflow loss during the flow process, and improving the stability of the airflow.

[0035] Optionally, the rotating part 200 has a bowl-shaped structure. In this way, the rotating part 200 is set into a bowl-shaped structure, which can guide the airflow of the air conditioner through the outer side of the bowl-shaped structure. It can cooperate with the air outlet of the air conditioner to make the air outlet of the air conditioner ring-shaped. The jet device can better drive the ring-shaped air outlet to deflect, so that the air conditioner as a whole has a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0036] Alternatively, a bowl-shaped structure refers to a structure that protrudes outward from the middle, narrows towards the center at the mouth and bottom, and has a smaller diameter at the mouth than at the middle. This makes the outer surface of the bowl-shaped structure arc-shaped, which, when applied to an air conditioner, guides the airflow and improves the air conditioner's efficiency.

[0037] Optionally, the opening of the bowl-shaped structure is positioned facing one end of the jet channel 100. In this way, the airflow in the jet channel 100 enters the rotating part 200 through the opening of the bowl-shaped structure, allowing the airflow in the jet channel 100 to enter the rotating part 200 stably, making the airflow smoother and improving the stability of the airflow.

[0038] Optionally, the bottom of the bowl-shaped structure is an arc-shaped surface. In this way, the arc-shaped surface structure can guide the airflow of the air conditioner and cooperate with the air outlet of the air conditioner to make the airflow of the air conditioner ring-shaped. The jet device can better drive the ring-shaped airflow deviation, so that the air conditioner as a whole has a variety of air outlet modes and improves the air outlet effect.

[0039] Optionally, one end of the jet channel 100 is provided with a horn-shaped connecting structure 400, and the diameter of the rim of the horn-shaped connecting structure 400 is the same as the diameter of the rim of the bowl-shaped structure. In this way, the jet channel 100 is connected to the bowl-shaped structure through the horn-shaped connecting structure 400. When installed in an air conditioner, the horn-shaped connecting structure 400 has a circumferential guiding effect on the airflow flowing outside it, so that the airflow forms an annular air outlet area under the guidance of the horn-shaped connecting structure 400, thereby improving the air outlet efficiency of the air conditioner.

[0040] Optionally, the rim of the flared connecting structure 400 and the rim of the bowl-shaped structure are connected by a bearing. This bearing makes the connection between the flared connecting structure 400 and the bowl-shaped structure more flexible, allowing relative rotation between them and improving the stability of the rotating part 200 of the bowl-shaped structure.

[0041] Optionally, the center of the rotating part 200 and the center of the jet channel 100 are on the same axis. This ensures that the airflow in the jet channel 100 can flow smoothly and stably toward the rotating part 200, further improving the airflow efficiency.

[0042] Optionally, one end of the horn-shaped connecting structure 400 is a first circular connecting port 401, and the other end is a second circular connecting port 402. The first circular connecting port 401 is connected to one end of the jet channel 100, and the second circular connecting port 402 is connected to one end of the rotating part 200. In this way, by connecting the first circular connecting port 401 and the second circular connecting port 402 of the horn-shaped connecting structure 400 to the jet channel 100 and the rotating part 200 respectively, the horn-shaped connecting structure 400 can tightly connect the jet channel 100 and the rotating part 200, ensuring that the airflow flows smoothly and stably from the jet channel 100 to the rotating part 200.

[0043] Optionally, the diameter of the first circular connection port 401 is smaller than the diameter of the second circular connection port 402. In this way, the horn-shaped connection structure 400 can more tightly connect the bowl-shaped structure to the jet channel. When installed in an air conditioner, the air outlet passes through the horn-shaped connection structure 400, which guides the airflow passing through it. Combined with the air outlet of the air conditioner, this creates a ring-shaped airflow, thus enabling the air conditioner to have various airflow modes and improving its airflow performance.

[0044] Optionally, the diameter of the first circular connection port 401 is half the diameter of the second circular connection port 402. This allows for stable guidance of the airflow passing through the horn-shaped connection structure 400, and, in conjunction with the air conditioner's outlet, ensures that the air conditioner's airflow is circular, thus enabling the air conditioner to have a variety of airflow modes and further improving its airflow performance.

[0045] Optionally, the smaller-diameter end of the tapered channel 103 is inserted into the flared connecting structure 400 via the first circular connection port 401 and connected to the rotating part 200. In this way, the smaller-diameter end of the tapered channel 103 is structurally more adaptable to the installation structure of the flared connecting structure 400, and can be inserted into the flared connecting structure 400, making installation simpler and easier to operate.

[0046] Optionally, the jet device further includes a drive device 202. The drive device 202 is connected to the rotating part 200 and is configured to drive the rotating part 200 to rotate. In this way, the drive device 202 provides power to the rotating part 200, so that the jet port 300 can rotate with the rotating part 200. As a result, when the airflow in the jet channel 100 is ejected through the jet port 300, the direction of the jet changes with the rotation of the rotating part 200, thereby changing the overall air outlet direction of the air conditioner.

[0047] Optionally, the drive device 202 includes: a ring gear 203, a gear 204, and a drive motor 205. The ring gear 203 is fixedly connected to one side of the rotating part 200, the gear 204 meshes with the ring gear 203, and the output shaft of the drive motor 205 is connected to the gear 204. Thus, the gear 204 rotates under the drive of the drive motor 205. Through the meshing structure between the gear 204 and the ring gear 203, the ring gear 203 rotates, thereby driving the rotating part 200 to rotate. This makes the drive more direct and efficient. Furthermore, under the drive of the drive device 202, the position of the jet outlet 300 on the rotating part 200 changes accordingly, thereby changing the direction of the airflow emitted from the jet outlet 300, allowing the jet outlet 300 to emit air in multiple directions. The ring gear 203 is located on the side of the rotating part 200 connected to the trumpet-shaped connecting structure 400.

[0048] Optionally, the drive motor 205 is fixedly installed inside the horn-shaped connecting structure 400. This not only makes reasonable use of the internal space of the horn-shaped connecting structure 400 and prevents the drive motor 205 from occupying a large installation space of the rotating part 200, but also ensures that the drive motor 205 does not affect the rotation of the rotating part 200, thereby improving the stability of the rotating part 200 during rotation.

[0049] Optionally, the drive motor 205 is fixed to the inner wall of the horn-shaped connecting structure 400 or the conical channel 103 via the motor bracket 206. This makes the drive motor 205 more securely fixed and improves the stability of the rotation of the drive rotating part 200.

[0050] Optionally, the jet nozzle 300 is positioned within a preset distance of the circumference of the bowl-shaped structure. When used in an air conditioner, the airflow from the air conditioner flows through the circumference of the bowl-shaped structure. Therefore, positioning the jet nozzle 300 within this preset distance allows the airflow from the jet nozzle 300 to be closer to the airflow from the air conditioner. This causes the airflow from the air conditioner to deflect with the airflow from the jet nozzle 300, improving the jetting effect and enhancing the overall airflow performance of the air conditioner. Furthermore, positioning the jet nozzle 300 within this preset distance allows the airflow from the jet nozzle 300 to form a certain angle with the airflow from the air conditioner, better driving changes in the overall airflow angle of the air conditioner. This enables the air conditioner to have various airflow modes, further improving the airflow performance.

[0051] Optionally, the jet nozzle 300 protrudes from the bowl-shaped structure and is inclined. This protrusion increases the jet nozzle's range, allowing it to deliver air further. Furthermore, the inclined arrangement of the jet nozzle on the bowl-shaped structure allows the airflow to form an angle with the air conditioner's outlet, better controlling the overall airflow angle and thus enabling the air conditioner to operate in various modes, further improving its performance.

[0052] Optionally, a guide vane 301 is provided on one side of the jet outlet 300. In this way, the guide vane 301 is provided on one side of the jet outlet 300, which has the function of guiding the air outlet of the jet outlet 300, changing the air outlet direction of the jet outlet 300, and increasing the air delivery distance of the jet outlet. In turn, the airflow ejected from the jet outlet 300 drives the overall air outlet angle of the air conditioner to shift, so that the air conditioner can have a variety of air outlet modes.

[0053] Optionally, the guide vane 301 is disposed on the side of the jet outlet 300 away from the center of the rotating part 200, and the guide vane 301 is inclined as a whole towards the center of the rotating part 200. In this way, it has a guiding effect on the air outlet of the jet outlet 300, causing the air outlet direction of the jet outlet 300 to deviate towards the center of the rotating part 200, thereby changing the air outlet direction of the jet outlet 300 and improving the air outlet effect.

[0054] Optionally, the preset distance is less than or equal to one-third of the radius of the bowl-shaped structure. If the preset distance is greater than one-third of the radius of the bowl-shaped structure, the airflow from the jet nozzle 300 will be farther from the air outlet of the air conditioner, thus reducing the impact of the airflow from the jet nozzle 300 on the air outlet. This would prevent the air outlet from shifting with the airflow from the jet nozzle 300, reducing the overall airflow efficiency of the air conditioner. Therefore, setting the preset distance to less than or equal to one-third of the radius of the bowl-shaped structure not only allows the airflow from the jet nozzle 300 to be closer to the air outlet of the air conditioner, and the air outlet will shift with the airflow from the jet nozzle 300, improving the overall airflow efficiency of the air conditioner, but also allows the airflow from the jet nozzle 300 to form a certain angle with the air outlet of the air conditioner, better driving changes in the overall air outlet angle of the air conditioner, thus enabling the air conditioner to have a variety of airflow modes.

[0055] Understandably, the preset distance is the distance between the circumference of the bowl-shaped structure and the jet opening 300.

[0056] Optionally, the rotating part 200 includes an airflow passage 201. The airflow passage 201 is disposed inside the rotating part 200, with one end connected to the jet channel 100 and the other end connected to the jet port 300. In this way, the airflow passage 201 connects the jet channel 100 and the jet port 300, providing a flow path for the airflow between the jet channel 100 and the jet port 300. This facilitates airflow delivery and also allows the airflow in the jet channel 100 to flow quickly to the jet port 300, improving the efficiency of airflow.

[0057] Optionally, the airflow passage 201 and the jet channel 100 are rotatably connected. This rotatable connection makes the connection between the airflow passage 201 and the jet channel 100 more flexible, ensuring that the airflow passage 201 and the jet channel 100 can rotate relative to each other, preventing the jet channel 100 from affecting the rotation of the airflow passage 201, and improving the stability of the rotation of the airflow passage 201.

[0058] Optionally, the airflow passage 201 is offset from the center of the rotating part 200 to the periphery. In this way, the inlet of the airflow passage 201 is located at the center of the rotating part 200, ensuring that the inlet of the airflow passage 201 and the airflow passage 201 remain on the same axis during the rotation of the rotating part 200. This maintains stable communication between the rotating part 200 and the airflow passage 201 during rotation, thereby improving the stability of the airflow. Furthermore, the offset of the airflow passage 201 from the center of the rotating part 200 to the periphery allows the outlet of the airflow passage 201 to face the jet outlet 300, thus stably delivering the airflow within the airflow passage 201 to the jet outlet 300, further improving airflow efficiency and the outlet efficiency of the jet outlet.

[0059] Optionally, the flow area of ​​the airflow passage 201 gradually decreases from the jet channel 100 to the jet outlet 300. In this way, due to the gradual decrease in the airflow flow area, the airflow passing through the airflow passage 201 changes from static pressure to dynamic pressure, increasing the airflow velocity and the outlet velocity of the jet outlet 300, thereby improving the jetting effect. Furthermore, the gradual decrease in flow area creates a funnel effect, increasing the airflow velocity and further enhancing the jetting effect.

[0060] Optionally, the maximum flow area of ​​the airflow passage 201 is greater than or equal to twice its minimum flow area, and less than or equal to four times its minimum flow area. Thus, when the maximum flow area of ​​the airflow passage 201 is less than twice its minimum flow area, the difference between the maximum and minimum flow areas is too small, resulting in a weak funnel effect within the airflow passage 201. This reduces the efficiency of the airflow converting from static pressure to dynamic pressure, leading to a slower increase in airflow velocity and consequently lowering the outlet velocity of the jet nozzle 300, thus reducing the jetting effect. Conversely, when the maximum flow area of ​​the airflow passage 201 is more than four times its minimum flow area, the difference between the maximum and minimum flow areas is too large, causing the airflow to flow too quickly towards the minimum flow area. This results in excessive airflow accumulation and congestion within the airflow passage 201, leading to excessive wind resistance and affecting normal airflow. Therefore, setting the maximum flow area of ​​the airflow passage 201 to between two and four times its minimum flow area allows for a funnel effect during airflow within the passage 201, increasing airflow velocity, while also reducing wind resistance and ensuring more stable airflow.

[0061] Optionally, the maximum flow area of ​​the airflow passage 201 is three times its minimum flow area. This ensures stable airflow within the airflow passage 201 while creating a funnel effect during the flow, increasing the airflow velocity and thus enhancing the jet effect.

[0062] Optionally, the jet nozzle 300 has an arc-shaped structure. This allows the airflow ejected from the jet nozzle 300 to form an arc-shaped surface, increasing the air outlet area of ​​the jet nozzle 300. This enables the air outlet of the jet nozzle 300 to better drive the change of the overall air outlet angle of the air conditioner, causing the air outlet of the air conditioner to deflect, thereby improving the jet effect.

[0063] Optionally, the arc of the jet nozzle 300 is greater than or equal to π / 3 and less than or equal to 2π / 3. When the arc of the jet nozzle 300 is less than π / 3, the nozzle becomes too small, causing airflow to accumulate at the nozzle, resulting in airflow congestion and preventing rapid ejection, thus reducing jet velocity and effect. When the arc of the jet nozzle 300 is greater than 2π / 3, the airflow is too smooth, preventing high-speed ejection, and the airflow from the nozzle 300 fails to affect the overall airflow of the air conditioner, reducing the airflow effect. Setting the arc between π / 3 and 2π / 3 allows the airflow from the jet nozzle 300 to better drive changes in the overall airflow angle of the air conditioner, causing the airflow to shift and thus improving the jet effect.

[0064] Combination Figure 7-8 As shown, this embodiment provides an air conditioner. It includes any of the jetting devices described above.

[0065] The air conditioner provided in this embodiment of the present disclosure has a rotating part 200 that blocks one end of the jet channel 100, and a jet port 300 is provided on the rotating part 200. The rotating part 200 can rotate with the rotating part 200, so that the airflow in the jet channel 100 flows out through the jet port 300. The direction of the jet changes with the rotation of the rotating part 200, which in turn can drive the overall air outlet of the air conditioner to change, so that the air conditioner has a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0066] Optionally, the air conditioner includes a housing 500 and an air outlet 600. The housing 500 internally defines an air outlet cavity 700, and a jetting device is disposed within the air outlet cavity 700. The housing 500 has an air outlet 600, which is centered on the jetting channel 100. Thus, with the jetting device located within the air outlet cavity 700, when the airflow within the air outlet cavity 700 is discharged through the air outlet 600, the air outlet of the air conditioner passes through the jetting device, which guides the airflow passing through it. Combined with the air outlet 600, this creates a ring-shaped airflow pattern, allowing the air conditioner to have various airflow modes and improving its overall airflow performance. Furthermore, the centered alignment of the air outlet 600 and the jetting channel 100 allows the airflow discharged within the jetting channel 100 to be closer to the air outlet of the air conditioner, causing the air outlet to deflect with the airflow ejected from the jetting port 600, further improving the overall airflow performance of the air conditioner.

[0067] Optionally, the air outlet 600 is a circular air outlet. In this way, the circular air outlet is structurally the same as the jet channel 100 and the rotating part 200. While ensuring a large area of ​​air outlet, it allows the airflow in the jet channel 100 to be smoothly directed through the jet port 300 on the rotating part 200 to the circular air outlet and discharged through the circular air outlet, further improving the airflow efficiency and ensuring the stability of the air outlet.
