Description

Technical Field

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

[0002] Air outlet devices need to meet the airflow requirements at different heights in various usage scenarios, such as on the ground or on a table. Therefore, the height or rotation angle of the air outlet device needs to be adjusted to meet different airflow heights and directions.

[0003] After the air outlet device is adjusted from a previous height to a new height, it needs to be locked to ensure that the air outlet device can be stably locked at the new height and blow air smoothly. However, the current locking mechanism of the air outlet device has two problems. First, if the air outlet device is to be locked stably, the locking structure is complex, the operation is complicated, and the user experience is poor. Second, if the goal is to make the locking of the air outlet device more convenient, the air outlet device is prone to falling due to its own weight or external forces, resulting in low locking reliability. Summary of the Invention

[0004] Therefore, it is necessary to provide an air outlet device and fan that are easy to operate and have high locking reliability.

[0005] In a first aspect, this application provides an air outlet device, comprising:

[0006] A chassis assembly, on which a first mating part is provided;

[0007] The head assembly, on which a second mating part is provided; and

[0008] An adjustment component is movably connected between the chassis component and the head assembly to adjust the distance between them in a preset direction;

[0009] The adjusting component is provided with a first limiting part and a second limiting part connected to the second cooperating part, and in the preset direction, the adjusting component has a first position and a second position;

[0010] When the adjustment component is in the first position, the first limiting part is connected to the first mating part, and the second limiting part is relatively stationary with respect to the second mating part; when the adjustment component is in the second position, the first limiting part is separated from the first mating part, and the second mating part can drive the first limiting part to move, so that the adjustment component is locked in the second position.

[0011] In some embodiments, the adjustment component includes a rotating shaft, and a first limiting portion extends axially along the rotating shaft and protrudes from the rotating shaft; the first mating portion is configured as a groove formed on the chassis component, and the rotating shaft and the first limiting portion are movable within the groove in the preset direction.

[0012] In some embodiments, when the adjusting component is in the first position, the first limiting portion is located within the slide groove and limits its position circumferentially along the rotating shaft;

[0013] When the adjustment component is in the second position, the first limiting part separates from the slide groove and can abut against the chassis component in the preset direction.

[0014] In some embodiments, the slide includes a first slot that mates with the rotating shaft and a second slot that mates with the first limiting portion. The inner contour of the first slot matches the projected contour of the rotating shaft in a plane perpendicular to its own axis, so that the rotating shaft can be inserted into the first slot.

[0015] And / or, the inner contour of the second slot matches the projected contour of the first limiting part in a plane perpendicular to the axis of rotation, so that the first limiting part can be inserted into the second slot.

[0016] In some embodiments, when the adjusting component is in the second position, the second mating part can move along the first direction to drive the rotating shaft to rotate circumferentially;

[0017] Wherein, the first direction is different from the circumferential direction of the rotating shaft.

[0018] In some embodiments, the second limiting portion is configured as a first gear sleeved on the rotating shaft along the axial direction of the rotating shaft, and the second engaging portion is configured as a second gear meshing with the first gear, wherein the axial direction of the second gear intersects with the axial direction of the first gear.

[0019] In some embodiments, the adjustment assembly includes a first cover, the rotating shaft is fixedly connected to the first cover and located within the first cover, and the first cover is movably disposed on the chassis assembly along the axial direction of the rotating shaft.

[0020] In some embodiments, the chassis assembly includes a base and a second cover, the second cover being fixed to the base, and the first mating part being disposed on the second cover;

[0021] The first cover is movably disposed on the second cover along the axial direction of the rotating shaft.

[0022] In some embodiments, the head assembly includes a protective cover and a fan blade, the fan blade being rotatably disposed within the protective cover, and the second mating part being disposed on the protective cover.

[0023] In some embodiments, the head assembly further includes a drive member connected to the fan blades, the drive member being used to drive the fan blades to rotate.

[0024] Secondly, this application provides a fan, including the air outlet device described above.

[0025] The aforementioned air outlet device and fan can adjust the distance between the head assembly and the chassis assembly through the adjustment component, thereby adjusting the air outlet height of the air outlet device. After the height adjustment is completed, the adjustment component is in the second position. At this time, the first limiting part is driven to move by the second mating part set on the head assembly, locking the adjustment component in the second position. That is, after the height of the head assembly is adjusted, the adjustment component can be locked by moving the head assembly, which is convenient for operation. Attached Figure Description

[0045] Air outlet devices often need to meet the airflow requirements at different heights in different usage scenarios, such as on the ground or on a table. Therefore, the air outlet device needs to be adjustable between different heights and able to stably lock at each height to achieve stable airflow at various levels.

[0046] Currently, there are two main locking methods used when adjusting the height of air outlet devices. First, a spring-loaded ball-operated mechanism is used. This method is simple and easy to operate, but the spring-loaded ball-operated mechanism cannot prevent the air outlet from falling due to external forces. Furthermore, with prolonged use, the spring-loaded ball-operated mechanism is prone to wear and failure, resulting in low locking reliability. Second, a manual latch is used. While this method has higher reliability, its structure and operation are very complex, leading to a poor user experience.

[0047] Based on the above considerations, the applicant, after in-depth research, has provided an air outlet device that can lock at a specific height by controlling the head assembly. The device has a simple structure and is easy to operate, effectively improving the user experience.

[0048] See Figure 1 and Figure 2 One embodiment of this application provides an air outlet device 100, including a chassis assembly 10, a head assembly 20, and an adjustment assembly 30. The chassis assembly 10 is provided with a first mating part 11, and the head assembly 20 is provided with a second mating part 21. The adjustment assembly 30 is movably connected between the chassis assembly 10 and the head assembly 20 to adjust the distance between them along a preset direction a. The adjustment assembly 30 is provided with a first limiting part 31 and a second limiting part 32 connected to the second mating part 21, and has a first position and a second position in the preset direction a.

[0049] When the adjusting component 30 is in the first position, the first limiting part 31 is connected to the first mating part 11, and the second limiting part 32 is stationary relative to the second mating part 21. When the adjusting component 30 is in the second position, the first limiting part 31 is separated from the first mating part 11, and the second mating part 21 can drive the first limiting part 31 to move, so that the adjusting component 30 is locked in the second position.

[0050] It should be noted that the chassis assembly 10 refers to the base of the air outlet device 100, which provides the mounting and support foundation for structures such as the head assembly 20 and the adjustment assembly 30. The head assembly 20 is the actual air-blowing structure of the air outlet device 100. Therefore, adjusting the distance between the head assembly 20 and the chassis assembly 10 along the preset direction a by adjusting the adjustment assembly 30 is equivalent to adjusting the air-blowing height of the air outlet device 100. Specifically, the greater the distance between the head assembly 20 and the chassis assembly 10, the higher the air-blowing height of the air outlet device 100; conversely, the smaller the distance between the head assembly 20 and the chassis assembly 10, the lower the air-blowing height of the air outlet device 100.

[0051] The adjustment component 30 engages with the first mating part 11 on the chassis component 10 via the first limiting part 31, thereby connecting the adjustment component 30 and the chassis component 10. The adjustment component 30 engages with the second mating part 21 on the head assembly 20 via the second limiting part 32, thereby connecting the adjustment component 30 and the head assembly 20.

[0052] When adjusting the distance between the chassis assembly 10 and the head assembly 20, the adjusting component 30 moves along a preset direction a, and has a first position and a second position during the movement. Therefore, the distance between the head assembly 20 and the chassis assembly 10 when the adjusting component 30 is in the first position is different from the distance when the adjusting component 30 is in the second position. That is, the process of the adjusting component 30 switching between the first and second positions is actually a process of adjusting the distance between the head assembly 20 and the chassis assembly 10, which is also a process of adjusting the blowing height of the air outlet device 100.

[0053] Specifically, when the adjustment component 30 is in the first position, the adjustment component 30 moves along the preset direction a through the cooperation between the first limiting part 31 and the first mating part 11. At this time, the second limiting part 32 on the adjustment component 30 and the second mating part 21 on the head assembly 20 are relatively stationary, ensuring that the adjustment component 30 moves smoothly in the preset direction a.

[0054] When the adjusting component 30 moves from the first position to the second position, the first limiting part 31 and the first mating part 11 separate, thereby allowing the second mating part 21 to drive the first limiting part 31 to move. During the movement of the first limiting part 31 driven by the second mating part 21, the head assembly 20 is actually driving the adjusting component 30 to move. This allows the head assembly 20 to be controlled to lock the adjusting component 30 in the second position, effectively locking the head assembly 20 at the height of the adjusting component 30 in the second position.

[0055] It should be noted that the first position is not limited to a fixed position, but may include multiple sub-positions arranged along a preset direction a. When the adjusting component 30 is in any of the sub-positions of the first position, the first limiting part 31 is connected to the first mating part 11, and the second limiting part 32 and the second mating part 21 are in a relatively stationary state.

[0056] The process of adjusting component 30 moving between multiple sub-positions in the first position is also the process of adjusting the distance between head assembly 20 and chassis assembly 10. When adjusting component 30 moves from a certain sub-position to the second position, the first limiting part 31 separates from the first mating part 11. At this time, the first limiting part 31 can be driven to move by the second mating part 21 on the head assembly 20, thereby driving the adjusting component 30 to move synchronously, so as to lock the adjusting component 30 in the second position.

[0057] With the above structure, after the distance between the head assembly 20 and the chassis assembly 10 is adjusted, the head assembly 20 can be locked at the height of the adjusting assembly 30 in the second position by controlling the head assembly 20, thereby conveniently and quickly adjusting the height of the air outlet device 100. The operation is simple.

[0058] Please refer to the following: Figure 1 and Figure 3 In some embodiments, the adjustment component 30 includes a rotating shaft 33, and a first limiting portion 31 extends axially along the rotating shaft 33 and protrudes from the rotating shaft 33. The first mating portion 11 is configured as a groove formed on the chassis component 10, and the rotating shaft 33 and the first limiting portion 31 are movable in the groove along a preset direction a.

[0059] It should be noted that the slide groove extends along a preset direction a, thereby allowing the rotating shaft 33 and the first limiting part 31 to move within the slide groove along the preset direction a.

[0060] Furthermore, the axial direction of the rotating shaft 33 is parallel to the preset direction a. Therefore, the rotating shaft 33 can extend and retract within the slide groove along the axial direction to adjust the distance between the head assembly 20 and the chassis assembly 10.

[0061] When the rotating shaft 33 moves in the groove, the first limiting part 31 can limit the rotating shaft 33 along the circumference of the rotating shaft 33, preventing the rotating shaft 33 from rotating in the circumference, so that the movement of the rotating shaft 33 along the preset direction a is more stable.

[0062] Please refer to Figure 4 and Figure 5 In some embodiments, when the adjusting component 30 is in the first position, the first limiting part 31 is located in the slide groove and limits it circumferentially along the rotating shaft 33. When the adjusting component 30 is in the second position, the first limiting part 31 is separated from the slide groove and can abut against the chassis component 10 in a preset direction a.

[0063] Specifically, the length of the first limiting part 31 in the axial direction of the rotating shaft 33 is less than the length of the rotating shaft 33. When the adjusting component 30 is in the first position, both the rotating shaft 33 and the first limiting part 31 are located in the slide groove, and the rotating shaft 33 and the first limiting part 31 can move axially within the slide groove. In addition, the first limiting part 31 can limit the rotating shaft 33 along the axial direction, preventing the rotating shaft 33 from rotating circumferentially within the slide groove, thereby ensuring that the rotating shaft 33 moves stably in the preset direction a within the slide groove.

[0064] When the adjusting component 30 is in the second position, the rotating shaft 33 is still located inside the slide groove, while the first limiting part 31 is separated from the slide groove and located outside the slide groove. At this time, the rotating shaft 33 can rotate circumferentially. After the rotating shaft 33 rotates a certain angle, under the gravity of the adjusting component 30 and the head assembly 20 connected to it, the first limiting part 31 can press downward against the chassis assembly 10, thereby locking the adjusting component 30 in the second position.

[0065] It should be noted that the first limiting part 31 can be configured as a continuous structure extending along the axial direction of the rotating shaft 33, and since the length of the first limiting part 31 along the axial direction of the rotating shaft 33 is less than the length of the rotating shaft 33, when the first limiting part 31 is located in the slide groove, the adjusting component 30 is located in the first position, and is limited by the first limiting part 31 along the circumferential direction of the rotating shaft 33. As the rotating shaft 33 moves in the slide groove along the preset direction a, when the first limiting part 31 moves to the outside of the slide groove, the adjusting component 30 moves from the first position to the second position. At this time, the first limiting part 31 releases its limitation on the rotating shaft 33 along its circumferential direction. When the rotating shaft 33 rotates a certain angle in the circumferential direction, the first limiting part 31 and the slide groove are misaligned. At this time, the first limiting part 31 can abut against the chassis component along the preset direction a, thereby locking the adjusting component 30 in the second position.

[0066] In addition, the first limiting part 31 may also be configured with multiple sub-limiting parts at intervals along the axial direction of the rotating shaft 33. Each sub-limiting part corresponds to a sub-position in the first position of the adjusting component 30, and the interval between each two adjacent sub-limiting parts corresponds to one of the second positions of the adjusting component 30.

[0067] Therefore, the adjustment component 30 in the above structure includes multiple second positions, which can lock the adjustment component 30 at multiple different heights, thereby achieving locking of the air outlet device 100 at different heights.

[0068] Please refer to Figure 6 In some embodiments, the slide includes a first slot 111 that mates with the rotating shaft 33 and a second slot 112 that mates with the first limiting part 31. The inner contour of the first slot 111 matches the projected contour of the rotating shaft 33 in a plane perpendicular to its own axis, so that the rotating shaft 33 can be inserted into the first slot 111. And / or the inner contour of the second slot 112 matches the projected contour of the first limiting part 31 in a plane perpendicular to the axis of the rotating shaft 33, so that the first limiting part 31 can be inserted into the second slot 112.

[0069] Please refer to Figure 7 and Figure 8 Specifically, the first slot 111 and the second slot 112 are interconnected, corresponding to the rotating shaft 33 and the first limiting part 31, respectively. When the adjusting component 30 is in the first position, the rotating shaft 33 is located in the first slot 111, and at the same time, the first limiting part 31 is located in the second slot 112. Thus, the first limiting part 31 can prevent the rotating shaft 33 from rotating circumferentially within the first slot 111.

[0070] Please refer to Figure 9 and Figure 10When the adjusting component 30 moves from the first position to the second position, the rotating shaft 33 remains within the first slot 111, while the first limiting part 31 separates from the second slot 112. At this time, the rotating shaft 33 can rotate circumferentially within the first slot 111.

[0071] Setting the inner contour of the first slot 111 to match the cross-sectional contour of the rotating shaft 33 makes the setting of the rotating shaft 33 in the first slot 111 more stable, avoids the rotating shaft 33 from shifting in the first slot 111, and thus makes the rotating shaft 33 move more stably in the preset direction a in the first slot 111.

[0072] By setting the inner contour of the second slot 112 to match the cross-sectional contour of the first limiting part 31, the first limiting part 31 can be better accommodated within the second slot 112. Furthermore, when the first limiting part 31 separates from the second slot 112, simply adjusting the rotating shaft 33 by a small angle in the circumferential direction will cause the first limiting part 31 and the second slot 112 to be offset from each other along the axial direction of the rotating shaft 33, so that the first limiting part 31 abuts against the chassis assembly in a preset direction a, thereby locking the adjusting component 30 in the second position.

[0073] Please refer to it again. Figure 1 and Figure 2 In some embodiments, when the adjusting component 30 is in the second position, the second mating part 21 can move along a first direction (not shown in the figure) to drive the rotating shaft 33 to rotate circumferentially. The first direction is different from the circumferential direction of the rotating shaft 33.

[0074] When the adjusting component 30 is in the second position, the first limiting part 31 and the second slot 112 are separated. At this time, by controlling the second mating part 21 to move in the first direction, the rotating shaft 33 is driven to rotate circumferentially, so that the first limiting part 31 and the second slot 112 are offset from each other in the axial direction of the rotating shaft 33. As a result, the first limiting part 31 can abut against the chassis component in the preset direction a, thereby locking the adjusting component 30 in the second position, thus completing the adjustment and fixing of the distance between the head assembly 20 and the chassis assembly 10.

[0075] In some embodiments, the second limiting part 32 is configured as a first gear sleeved on the rotating shaft 33 along the axial direction of the rotating shaft 33, and the second engaging part 21 is configured as a second gear meshing with the first gear, wherein the axial direction of the second gear intersects with the axial direction of the first gear.

[0076] Specifically, the first direction is the circumferential direction of the second gear, and the movement of the second mating part 21 along the first direction is equivalent to the rotation of the second gear along the circumferential direction.

[0077] Furthermore, the first gear and the second gear mesh with each other, and the axis of the second gear is perpendicular to the axis of the first gear. The second gear is fixed to the head assembly 20, allowing the second gear to rotate circumferentially by adjusting the pitch angle of the head assembly 20. Furthermore, the second gear drives the first gear to rotate circumferentially, and the first gear drives the rotating shaft 33 to rotate synchronously. This causes the first limiting part 31 to be offset from the second slot 112 axially on the rotating shaft 33, allowing the first limiting part 31 to press downwards against the chassis assembly 10 under its own weight, thus locking the head assembly 20.

[0078] With the above structure, when the adjustment component 30 moves from the first position to the second position, the head assembly 20 can be locked at the height of the adjustment component 30 in the second position simply by adjusting the pitch angle of the head assembly 20. The operation is simple, the structure is simple, and the locking reliability is high.

[0079] Please refer to the following: Figure 1 , Figure 11 and Figure 12 In some embodiments, the adjustment component 30 includes a first cover 34, a rotating shaft 33 is fixedly connected to the first cover 34 and located inside the first cover 34, and the first cover 34 is movably disposed on the chassis component 10 along the axial direction of the rotating shaft 33.

[0080] The first cover 34 can move synchronously with the rotating shaft 33 along the axial direction of the rotating shaft 33, and house the rotating shaft 33 within the first cover 34. This provides a certain degree of protection for the rotating shaft 33 and also makes the overall structure of the air outlet device 100 more aesthetically pleasing.

[0081] In some embodiments, the chassis assembly 10 includes a base 12 and a second cover 13, the second cover 13 being fixed to the base 12, and a first mating part 11 being disposed on the second cover 13. The first cover 34 is movably disposed on the second cover 13 along the axial direction of the pivot 33.

[0082] Specifically, the second cover 13 is fixed on the base 12, and a slide groove is opened on the top of the second cover 13, so that the rotating shaft 33 can be inserted into the slide groove from top to bottom and move back and forth in the slide groove to adjust the height of the head assembly 20.

[0083] Furthermore, the first cover 34 is slidably fitted onto the second cover 13, that is, the first cover 34 is slidably connected to the second cover 13 along the axial direction of the rotating shaft 33. Specifically, the first cover 34 and the second cover 13 can be slidably connected by a sliding groove and a slider, or other structures can be used to achieve the slidable connection, which will not be elaborated here.

[0084] When the rotating shaft 33 reciprocates within the groove, the first cover 34 can follow the rotating shaft 33 and move relative to the second cover 13 in a preset direction a.

[0085] In some embodiments, the head assembly 20 includes a protective cover 22 and a fan blade 23, the fan blade 23 being rotatably disposed within the protective cover 22, and a second mating part 21 being disposed on the protective cover 22.

[0086] Specifically, the fan blade 23 generates airflow by rotating, thereby realizing the blowing function of the air outlet device 100. The second gear is fixed to the protective cover 22. When the pitch angle of the protective cover 22 is adjusted, the fan blade 23 inside the protective cover 22 will move synchronously with the protective cover 22. At the same time, the protective cover 22 drives the second gear fixed thereon to rotate, thereby driving the first gear meshing with it to rotate, which in turn drives the rotating shaft 33 to rotate, so as to lock the protective cover 22 and the fan blade 23.

[0087] Understandably, the second gear can be fixed to the protective cover 22 by the engagement of a screw and a screw post. Before the second gear is fixed to the protective cover 22, it is inserted into the first cover 34 to facilitate smooth engagement between the second gear and the first gear. Then, the second gear is fixed to the protective cover 22, so that the first cover 34 is sandwiched between the second gear and the protective cover 22.

[0088] In some embodiments, the head assembly 20 further includes a drive member (not shown) that is driven to drive the fan blade 23 to rotate.

[0089] The drive component can drive the fan blade 23 to rotate inside the protective cover 22, thereby realizing the blowing function of the air outlet device 100. Specifically, the drive component can be a motor or other drive structure, which will not be described in detail here.

[0090] Based on the same concept as the air outlet device 100 described above, this application also provides a fan, including the air outlet device 100 as described above.

[0091] When this application is used, the base 12 is placed on the ground or table, and the protective cover 22 is lifted upward. The rotating shaft 33 moves upward in the slide groove. At this time, since the first limiting part 31 is located in the second groove 112, the rotating shaft 33 cannot rotate and can only move upward.

[0092] When the protective cover 22 moves upward to the target height, the first limiting part 31 moves to the outside of the second slot 112, at which point the rotating shaft 33 can rotate. Adjusting the pitch angle of the protective cover 22 causes the second gear on the protective cover 22 to rotate, thereby driving the first gear meshing with it to rotate. The first gear drives the rotating shaft 33 to rotate, causing the first limiting part 31 to be misaligned with the second slot 112 in the axial direction of the rotating shaft 33. Thus, the first limiting part 31 can press against the second cover 13 under its own weight, locking the protective cover 22 at the target height.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
