[0037] See Figures 1 to 7 As shown, this utility model discloses a specific embodiment of an air duct mechanism, including: a housing 110 and a first volute tongue 130. The housing 110 is provided with a first receiving cavity 121, a first air outlet channel 122 and a first air duct 123. The first air outlet channel 122 and the first air duct 123 are both connected to the first receiving cavity 121. The first volute tongue 130 is rotatably disposed in the first receiving cavity 121, and a first air guide cavity 140 is formed between the first volute tongue 130 and the housing 110.

[0038] When the first volute tongue 130 rotates to the first air outlet position, the first air guide cavity 140 is connected to the first air outlet channel 122; when the first volute tongue 130 rotates to the second air outlet position, the first air guide cavity 140 is connected to the first air duct 123.

[0039] Specifically, the housing 110 includes a cover 111 and a back plate 112 connected to the cover 111. The cover 111 and / or the back plate 112 are provided with sidewalls 1111, so that a first receiving cavity 121, a first air outlet channel 122 and a first air duct 123 are formed between the cover 111 and the back plate 112, and a first air guide cavity 140 is formed between the first volute tongue 130 and the cover 111 and the back plate 112. A first fan 150 is also installed in the first receiving cavity 121, and the first volute tongue 130 is located on the outer periphery of the first fan 150. The cover 111 is provided with an air inlet 1112 corresponding to the position of the first fan 150, so that when the first fan 150 rotates, the gas enters the first air guide cavity 140 from the air inlet 1112. When gas is needed to flow out from the first air outlet channel 122, the first volute 130 rotates within the first receiving cavity 121 to the first air outlet position, so that the first air guide cavity 140 is connected to the first air outlet channel 122, while the first air duct 123 is not connected to the first air guide cavity 140 (i.e., the first air duct 123 is in a non-conductive state). When gas is needed to flow out from the first air duct 123, the first volute 130 rotates within the first receiving cavity 121 to the second air outlet position, so that the first air guide cavity 140 is connected to the first air duct 123, while the first air outlet channel 122 is not connected to the first air guide cavity 140 (i.e., the first air outlet channel 122 is in a non-conductive state). This air duct mechanism 100, by designing the rotation of the first volute 130, can flexibly switch the gas outlet channel, thereby changing the air outlet direction of the air duct mechanism 100 to adapt to different usage requirements.

[0040] In one specific embodiment, the first volute tongue 130 includes a volute tongue body 131 and a first air guide plate 132 connected to the volute tongue body 131, and both the volute tongue body 131 and the first air guide plate 132 abut against the inner side of the housing 110, so that a first air guide cavity 140 is formed between the inner side of the first volute tongue 130 and the housing 110.

[0041] Specifically, the volute tongue body 131 is in the shape of an open ring. The first air guide plate 132 is connected to the end of the volute tongue body 131. Both the volute tongue body 131 and the first air guide plate 132 abut against the inner side of the housing 110. When the first air guide cavity 140 is connected to the first air outlet channel 122 or the first air duct 123, the end of the volute tongue body 131 away from the first air guide plate 132 and the end of the first air guide plate 132 away from the volute tongue body 131 are respectively transitionally connected to the side walls 1111 on both sides of the first air outlet channel 122 or the first air duct 123.

[0042] By setting the volute tongue body 131 to an open annular shape and cooperating with the first air guide plate 132, gas can be guided more effectively to flow in the first air guide cavity 140, and the direction of gas flow can be controlled. By adjusting the position and shape of the volute tongue body 131 and the first air guide plate 132, the airflow path can be optimized, eddies and resistance can be reduced, and the gas flow efficiency can be improved. Both the volute tongue body 131 and the first air guide plate 132 abut against the inner side of the housing 110, forming a tight first air guide cavity 140. This design can prevent gas leakage and ensure that gas can flow out accurately through the first air outlet channel 122 or the first air duct 123, improving the sealing and performance of the air duct mechanism 100.

[0043] In one specific embodiment, the first air guide plate 132 is an arc-shaped plate.

[0044] Specifically, the arc-shaped plate design better guides the flow of gas within the first air guide cavity 140. Compared to straight lines or other shapes, the arc-shaped plate provides a smoother transition, reducing eddies and resistance during gas flow, thus ensuring smoother entry of gas into the first air outlet channel 122 or the first air duct 123. Simultaneously, right angles or sharp edges during gas flow can generate turbulence and noise; the arc-shaped plate design reduces these angles, thereby lowering the noise level during gas flow and improving the quietness of the air duct mechanism 100. Furthermore, the contact surface between the arc-shaped plate and the inner side of the housing 110 more easily forms a tight seal, which helps prevent gas leakage. By ensuring the airtightness of the first air guide cavity 140, it is ensured that gas can accurately flow out through the predetermined air outlet channel, thereby improving the performance and efficiency of the air duct mechanism 100.

[0045] In one specific embodiment, the air duct mechanism 100 further includes a second volute tongue 160, and the housing 110 is also provided with a second receiving cavity 124, a second air outlet channel 125 and a second air duct 126. The second air outlet channel 125 and the second air duct 126 are both connected to the second receiving cavity 124. The second volute tongue 160 is rotatably disposed in the second receiving cavity 124, and a second air guide cavity 170 is formed between the second volute tongue 160 and the housing 110.

[0046] Specifically, a second fan 151 is also installed inside the second receiving cavity 124. The structure and working principle of the second fan 151, the second volute 160, the second receiving cavity 124, the second air outlet channel 125, and the second air duct 126 are the same as those of the first fan 150, the first volute 130, the first receiving cavity 121, the first air outlet channel 122, and the first air duct 123. Furthermore, through the above design, the air duct mechanism 100 can simultaneously discharge air in two directions. Combined with the first fan 150 and the second fan 151, the air duct mechanism 100 can achieve both unidirectional and bidirectional air discharge, thereby improving the flexibility and practicality of the air discharge from the air duct mechanism 100.

[0047] It is understood that in other embodiments, the number of fans, volutes, receiving cavities and air outlet channels can be further changed according to actual conditions, so that the air outlet of the air duct mechanism 100 is more flexible.

[0048] In one specific embodiment, the first receiving cavity 121 is a circular cavity.

[0049] Specifically, both the first receiving cavity 121 and the second receiving cavity 124 are circular in shape, with the center of the first receiving cavity 121 concentric with the rotation center of the first volute tongue 130, and the center of the second receiving cavity 124 concentric with the rotation center of the second volute tongue 160. This concentric design ensures that the first volute tongue 130 and the second volute tongue 160 always rotate around a fixed central axis, reducing friction and collision between the first volute tongue 130 and the second volute tongue 160 and the housing 110. This effectively maintains the stability of the first volute tongue 130 and the second volute tongue 160 and avoids offset or tilting. Therefore, this design can extend the service life of the air duct mechanism 100, reduce mechanical wear, and improve the reliability of the air duct mechanism 100.

[0050] In one specific embodiment, the housing 110 is further provided with a third air outlet channel 127 and a fourth air outlet channel 128. The third air outlet channel 127 is connected to the first receiving cavity 121, and the fourth air outlet channel 128 is connected to the second receiving cavity 124.

[0051] Specifically, by increasing the number of air outlet channels, the air outlet of the air duct mechanism 100 can be made more flexible.

[0052] In one specific embodiment, the two ends of the first air duct 123 are respectively connected to the first receiving cavity 121 and the second receiving cavity 124. A first air guide channel 141 is formed between the outer side of the first volute tongue 130 and the housing 110, and a second air guide channel 171 is formed between the outer side of the second volute tongue 160 and the housing 110. The first air guide channel 141 is used to connect the third air outlet channel 127 and the first air duct 123, and the second air guide channel 171 is used to connect the fourth air outlet channel 128 and the first air duct 123.

[0053] Specifically, a gap is provided between the outer side of the volute tongue body 131 and the side wall 1111, so that a first air guide channel 141 is formed between the outer side of the volute tongue body 131, the side of the first air guide plate 132 away from the first air guide cavity 140, and the housing 110. Similarly, a second air guide channel 171 is provided between the outer side of the second volute tongue 160 and the housing 110. The ends of the first air outlet channel 122 and the third air outlet channel 127 away from the first receiving cavity 121 are both connected to the first air outlet (not shown in the figure), and the ends of the second air outlet channel 125 and the fourth air outlet channel 128 away from the second receiving cavity 124 are both connected to the second air outlet (not shown in the figure). Through the above design, the air duct mechanism 100 in this embodiment can form at least three air outlet states when both the first fan 150 and the second fan 151 are working.

[0054] In the first air outlet state: both the first fan 150 and the second fan 151 discharge air through the first air outlet, while the second air outlet is in a non-conductive state. Specifically, the first volute 130 rotates within the first receiving cavity 121 to the first air guide cavity 140, connecting to the first air outlet channel 122, and the two ends of the first air guide channel 141 are respectively connected to the third air outlet channel 127 and the first air duct 123; while the second volute 160 rotates within the second receiving cavity 124 to the second air guide cavity 170, connecting to the first air duct 123, while the second air outlet channel 125 and the fourth air outlet channel 128 are in a non-conductive state. At this time, the airflow blown out by the first fan 150 flows directly from the first air guide cavity 140 to the first air outlet 122 and finally flows out from the first air outlet. Meanwhile, the airflow blown out by the second fan 151 flows from the second air guide cavity 170 through the first air duct 123, the first air guide cavity 141 and the third air outlet 127 in sequence, and finally flows out from the first air outlet. This achieves the goal of both the first fan 150 and the second fan 151 blowing air in the same direction from the first air outlet.

[0055] Second air outlet state: Both the first fan 150 and the second fan 151 outlet air is discharged through the second air outlet, and the first air outlet is in a non-conductive state. Specifically, the second volute 160 rotates within the second receiving cavity 124 to the second air guide cavity 170, connecting to the second air outlet channel 125, and the two ends of the second air guide channel 171 are respectively connected to the fourth air outlet channel 128 and the first air duct 123; while the first volute 130 rotates within the first receiving cavity 121 to the first air guide cavity 140, connecting to the first air duct 123, and the first air outlet channel 122 and the third air outlet channel 127 are in a non-conductive state. At this time, the airflow blown out by the first fan 150 flows from the first air guide cavity 140 through the first air duct 123, the second air guide channel 171 and the fourth air outlet channel 128 in sequence, and finally flows out from the second air outlet. Meanwhile, the airflow blown out by the second fan 151 flows directly from the second air guide cavity 170 to the second air outlet channel 125, and finally flows out from the second air outlet, thus achieving that both the first fan 150 and the second fan 151 blow out air in the same direction from the second air outlet.

[0056] In the third air outlet state: the first fan 150 discharges air through the first air outlet, and the second fan 151 discharges air through the second air outlet. Specifically, the first volute 130 rotates within the first receiving cavity 121 to the first guide cavity 140, connecting to either the first air outlet channel 122 or the third air outlet channel 127; the second volute 160 rotates within the second receiving cavity 124 to the second guide cavity 170, connecting to either the second air outlet channel 125 or the fourth air outlet channel 128. At this time, the airflow from the first fan 150 flows directly from the first guide cavity 140 to the first air outlet channel 122 or the third air outlet channel 127, and finally exits from the first air outlet. Conversely, the airflow from the second fan 151 flows directly from the second guide cavity 170 to the second air outlet channel 125 or the fourth air outlet channel 128, and finally exits from the second air outlet, thus achieving simultaneous air discharge from both the first and second fans on opposite sides of the first and second air outlets, respectively.

[0057] In the first air outlet state, the second air guide cavity 170 is sequentially connected to the first air duct 123, the first air guide channel 141, and the third air outlet channel 127. The first air guide cavity 140 is directly connected to the first air outlet channel 122, so that the first fan 150 and the second fan 151 both discharge air in the same direction at the first air outlet, thereby effectively increasing the air volume of the first air outlet. In the second air outlet state, the first air guide cavity 140 is sequentially connected to the first air duct 123, the second air guide channel 171, and the fourth air outlet channel 128. The second air guide cavity 170 is directly connected to the second air outlet channel 125, so that the first fan 150 and the second fan 151 both discharge air in the same direction at the second air outlet, thereby effectively increasing the air volume of the second air outlet. In the third air outlet state, the first and second air outlets discharge air synchronously in two directions, which can achieve efficient air circulation, improve the overall cooling / heating effect, and avoid excessive energy consumption. Furthermore, by coordinating the switching and adjustment of the first fan 150 and the second fan 151, the airflow of the duct mechanism 100 can be more precisely adjusted, greatly improving the flexibility and practicality of the airflow mechanism. With the first air duct 123 and multiple air outlet channels, and in conjunction with the rotation of the volute tongue, the duct mechanism 100 can flexibly switch between different airflow states as needed, achieving airflow in different directions and quantities. Moreover, although the duct mechanism 100 in this embodiment provides at least three airflow states where both the first fan 150 and the second fan 151 are operating, the entire switching process only requires rotational control via the first volute tongue 130 and the second volute tongue 160 to complete all switching processes. It does not require complex mechanical devices or multiple independent valves, making the duct mechanism 100 more reliable, reducing maintenance costs, decreasing component wear, improving the reliability of the duct mechanism 100, extending its lifespan, and reducing maintenance frequency and costs.

[0058] In one specific embodiment, a second air guide plate 133 is also connected to the outside of the volute tongue body 131, and the second air guide plate 133 abuts against the housing 110, so that a first air guide channel 141 is formed between the first air guide plate 132, the volute tongue body 131 and the second air guide plate 133 and the housing 110.

[0059] Specifically, when the first air duct 123 is connected to the third air outlet duct 127 via the first air guide channel 141, the second air guide plate 133 abuts against the side wall 1111 of the first air duct 123 away from the third air outlet duct 127, and the first air guide plate 132 abuts against the side wall 1111 of the third air outlet duct 127 away from the first air duct 123. This ensures that when the airflow from the second air guide cavity 170 flows out of the first air duct 123, it is directly guided by the second air guide plate 133 into the first air guide channel 141, and finally guided by the first air guide plate 132 into the third air outlet duct 127. The introduction of the second air guide plate 133 allows the first volute tongue 130 to more precisely control the opening of the first air guide channel 141 when rotating, thereby controlling the airflow to a specific duct and preventing airflow leakage in unwanted directions. Simultaneously, it works in conjunction with the first air guide plate 132 to ensure that the airflow can flow along a predetermined path. This helps optimize the airflow path, reduce unnecessary energy loss, and improve the overall efficiency of the air duct mechanism 100. It is understood that the structure of the second volute tongue 160 is the same as that of the first volute tongue 130. Similarly, the connection method between other air ducts and the first air guide channel 141 or the second air guide channel 171 can be understood.

[0060] In one specific embodiment, the volute tongue body 131, the first air guide plate 132, and the second air guide plate 133 are integrally formed structures.

[0061] Specifically, the one-piece molding design eliminates any gaps or interfaces between the parts of the first volute 130 and the second volute 160, significantly enhancing their overall structural strength. This increased strength helps the first volute 130 and the second volute 160 maintain a stable shape and position during rotation, reducing performance degradation caused by deformation or loosening. Simultaneously, since the parts of the first volute 130 and the second volute 160 are integrally molded, there are no leakage issues at their joints. This ensures that airflow does not leak from unnecessary gaps when the first volute 130 and the second volute 160 rotate to different positions, thereby improving the air outlet efficiency of the duct mechanism 100. Furthermore, the one-piece molding design simplifies the manufacturing process of the first volute 130 and the second volute 160. Traditional manufacturing processes may require assembling multiple parts through welding, bolting, or other methods, which not only increases manufacturing costs but may also introduce performance problems at the joints. The one-piece molding avoids these problems, making the manufacturing of the first volute 130 and the second volute 160 simpler and more efficient. Furthermore, the one-piece molding of all parts of the first volute 130 and the second volute 160 allows the first volute 130 to more precisely control the direction and distribution of airflow. This helps optimize the airflow path, reduce eddies and resistance, and improve the airflow efficiency and stability of the duct mechanism 100.

[0062] In one specific embodiment, the two ends of the second air duct 126 are respectively connected to the first receiving cavity 121 and the second receiving cavity 124.

[0063] Specifically, the first air duct 123 is located on the same side as the third air outlet duct 127 and the fourth air outlet duct 128, while the second air duct 126 is located on the other side as the first air outlet duct 122 and the second air outlet duct 125. When the second air duct 126 is in the conductive state, the first air guide cavity 140 is directly connected to the third air outlet duct 127, and the second air guide cavity 170 is sequentially connected to the second air duct 126, the first air guide duct 141, and the first air outlet duct 122, so that both the first air guide cavity 140 and the second air guide cavity 170 are connected to the first air outlet; or, the second air guide cavity 170 is directly connected to the fourth air outlet duct 128, and the first air guide cavity 140 is sequentially connected to the second air duct 126, the second air guide duct 171, and the second air outlet duct 125, so that both the first air guide cavity 140 and the second air guide cavity 170 are connected to the second air outlet; thereby, the first fan 150 and the second fan 151 can achieve airflow in the same direction at the first air outlet or the second air outlet through the second air duct 126. The second air duct 126 and the first air duct 123 serve as backup channels for each other, so that if one air duct fails or becomes blocked, the other air duct can still continue to operate, ensuring a continuous supply of airflow. This design improves the fault tolerance of the air duct mechanism 100 and reduces the risk of the air duct mechanism 100 being paralyzed due to a single point of failure.

[0064] Furthermore, when the first air duct 123 or the second air duct 126 is connected to the first air guide channel 141 or the second air guide channel 171, the second air guide plate 133 is located between the first air duct 123 and the second air duct 126. This allows the second air guide plate 133 and the volute body 131 to close the other air duct when either the first air duct 123 or the second air duct 126 is open, thereby preventing backflow and disordered airflow between the two channels, thus improving airflow efficiency and stability. This design helps reduce energy loss and improves the overall performance of the air duct mechanism 100.

[0065] In one specific embodiment, the air duct mechanism 100 further includes a drive assembly 180, which is drively connected to the volute tongue body 131.

[0066] Specifically, the drive assembly 180 is mounted on the back plate 112, and the drive assembly 180 is used to drive the entire volute tongue to rotate around the rotation center. By setting the drive assembly 180, the rotational accuracy of the volute tongue can be improved, thereby making the adjustment of the volute tongue more precise and convenient, and making the adjustment of the airflow direction more flexible. In this embodiment, there are two sets of drive assemblies 180, and the two sets of drive assemblies 180 have the same transmission method as the first volute tongue 130 and the second volute tongue 160. It is understood that in other embodiments, the number of drive assemblies 180 can be set to different numbers according to different needs.

[0067] In one specific embodiment, the drive assembly 180 includes a drive member 181, a gear 182 and a rack 183. The drive member 181 is mounted on the housing 110, and the drive member 181, the gear 182 and the rack 183 are sequentially connected in a transmission manner. The rack 183 is connected to the volute tongue body 131.

[0068] Specifically, the drive unit 181 is mounted on the back plate 112 and has an output shaft that is driven by the gear 182. The rack 183 is located between the first air guide plate 132 and the second air guide plate 133 and is set along the arc of the volute tongue body 131. When it is necessary to adjust the position of the first volute tongue 130 to change the airflow direction, the drive unit 181 is activated, causing the output shaft of the drive unit 181 to start rotating. The gear 182 also rotates accordingly, and the rack 183 moves along the tooth surface of the gear 182. As the rack 183 moves, the first volute tongue 130 rotates around the rotation center, thereby changing the position of the first air guide cavity 140 to achieve the switching of the airflow direction. Through the transmission mechanism between the gear 182 and the rack 183, the rotation angle and speed of the first volute tongue 130 can be precisely controlled, thereby improving the adjustment accuracy of the airflow direction. The gear 182 and rack 183 provide smooth transmission, reducing vibration and impact on the first volute tongue 130 during rotation and improving the stability of the entire air duct mechanism 100. Simultaneously, the drive assembly 180 is directly mounted on the back plate 112 and directly connected to the volute tongue body 131, simplifying the structure of the air duct mechanism 100 and reducing manufacturing costs. Furthermore, the high transmission efficiency between the gear 182 and rack 183 reduces energy loss, improves the overall working efficiency of the air duct mechanism 100, and the relatively simple structure of the drive assembly 180 facilitates disassembly and maintenance, reducing maintenance costs.

[0069] More specifically, the volute tongue body 131 is equipped with racks 183 on both the side near the back plate 112 and the side near the top plate. The design of the volute tongue body 131 with double-sided racks 183 ensures that the first volute tongue 130 experiences more even force during rotation, reducing deflection or jamming caused by unilateral force. Simultaneously, this design enhances the structural stability of the first volute tongue 130 and extends its service life.

[0070] In one specific embodiment, a sensor is provided inside the air duct mechanism 100, and the sensor is electrically connected to the drive component 181.

[0071] Specifically, two sensors are used: one sensor detects the real-time position of the first volute tongue 130, and the other sensor detects the real-time position of the second volute tongue 160. By using sensors to detect the real-time positions of the first volute tongue 130 and the second volute tongue 160, and in conjunction with the drive unit 181, the positions of the first volute tongue 130 and the second volute tongue 160 can be precisely controlled, thereby allowing for more flexible adjustment of the airflow distribution and direction. It is understood that in other embodiments, limiting structures 190, such as pins or flanges, can be set on the housing 110 at positions corresponding to the start and end points of the rotation of the first volute tongue 130 and the second volute tongue 160. When the first volute tongue 130 or the second volute tongue 160 rotates to its end point, the limiting structure 190 will block its rotation. In conjunction with the drive unit 181, this will cause the first volute tongue 130 or the second volute tongue 160 to stop rotating after reaching its end point, thus achieving accurate volute tongue rotation position.

[0072] See Figure 8 and Figure 9 As shown, this utility model also provides an air conditioner, which includes the air duct mechanism 100 as described above.

[0073] Specifically, the air conditioner also includes an air inlet panel 200 and an air outlet frame mechanism 300. The air inlet panel 200 is provided corresponding to the cover 111, and the air outlet frame mechanism 300 is connected to the housing 110 and communicates with the first air outlet and / or the second air outlet.

[0074] The air conditioner provided in this embodiment allows for flexible adjustment of airflow distribution and direction through the rotation of the volute tongue in the duct mechanism 100. This enables the air conditioner, including the duct mechanism 100, to easily switch the airflow direction according to different usage needs. This design improves the airflow control capability of the air conditioner, making it adaptable to various usage scenarios. The fan in the duct mechanism 100 efficiently draws in air through the air inlet 1112 and sends it into the air guide cavity for further processing and distribution. This layout optimizes the airflow path, reduces airflow loss, and improves the energy efficiency of the air conditioner. The air conditioner includes an air inlet panel 200 and an air outlet frame mechanism 300, which work closely with the duct mechanism 100 to ensure smooth airflow. Furthermore, due to the high flexibility of the duct mechanism 100, the air conditioner including it also has strong adaptability. Whether in a home, office, or other location, this air conditioner can control airflow according to actual needs, providing a comfortable indoor environment. By precisely controlling the direction and distribution of airflow, this air conditioner can provide users with a more personalized user experience. Users can adjust the airflow direction according to their own needs to achieve more precise temperature and humidity control and improve their quality of life.

[0075] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
