[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0042] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] Embodiment 1:

[0044] like Figures 1 to 7 As shown, a manual adjustment device for a blade-hidden air outlet of the present invention comprises: a shell 1, which is provided with an air outlet channel 10; an upper hidden blade 20 and a lower hidden blade 21, which are movably arranged on the upper and lower sides of the shell 1 respectively; a horizontal blade 3 and a track connecting rod 4, wherein the horizontal blade 3 is rotatably installed in the air outlet channel 10 of the shell 1, and is used to adjust the main air outlet direction of the air outlet channel 10; the middle position of the track connecting rod 4 is movably connected to the horizontal blade 3, and the upper and lower ends of the track connecting rod 4 are movably connected to the upper hidden blade 20 and the lower hidden blade 21 respectively; when the horizontal blade 3 rotates to the upper limit position relative to the shell 1, the track connecting rod 4 can drive the lower hidden blade 21 to swing into the air outlet channel 10, and the upper hidden blade 20 remains stationary and close to the top wall of the air outlet channel 10; when the horizontal blade 3 rotates to the lower limit position relative to the shell 1, the track connecting rod 4 can drive the upper hidden blade 20 to swing into the air outlet channel 10, and the lower hidden blade 21 remains stationary and close to the bottom wall of the air outlet channel 10.

[0045] Specifically, Figure 1 to Figure 2 As shown, without any adjustment, the upper hidden blade 20 and the lower hidden blade 21 are respectively attached to the top wall and the bottom wall of the air outlet channel 10, and the air passes through the air outlet channel 10 directly along the Figure 2 The air is blown out in the direction shown to achieve the normal ventilation function. Figure 2When the user needs to adjust the wind direction to blow air upward, the horizontal blade 3 can be rotated to the lower limit position through manual operation. When the horizontal blade 3 rotates, the movable connection point between the horizontal blade 3 and the middle position of the track link 4 moves accordingly. Since the upper and lower ends of the track link 4 are respectively movably connected to the upper hidden blade 20 and the lower hidden blade 21, when the horizontal blade 3 is rotated, the lower hidden blade 21 is moved upward. Figure 2 Status turns to Figure 4 During the state, the upper end of the track link 4 will drive the upper hidden blade 20 to swing into the air outlet channel 10, while the lower hidden blade 21 remains stationary and close to the bottom wall of the air outlet channel 10, which will not affect the airflow direction, so that the air can be blown out along the inclined upward cavity formed by the horizontal blade 3 and the upper hidden blade 20, achieving a precise blowing effect; similarly, when the user rotates the horizontal blade 3 to Figure 5 During the process of the state shown, the lower end of the track link 4 drives the lower hidden blade 21 to swing into the air outlet channel 10, and the upper hidden blade 20 remains stationary and close to the top wall of the air outlet channel 10 during this process, without interfering with the airflow, so as to realize the function of blowing air downward at the air outlet. It can be seen that the air outlet structure can adjust the air outlet direction according to actual needs through the coordinated work of the horizontal blade 3 and the upper / lower hidden blades 21, whether it is blowing upward or downward, and can achieve more accurate wind direction control with the auxiliary blowing of the upper / lower hidden blades 21, and can also be in the normal main blowing state of the horizontal blade 3 (such as Figure 2 The upper / lower hidden blades 21 are in the state shown in the figure, so that the upper / lower hidden blades 21 are fitted to the inner wall of the shell 1, reducing the occupation of the internal space, effectively ensuring the overall aesthetics, and also satisfying the blowing effect and comfort brought by the user when blowing.

[0046] The track link 4 includes a connecting portion 40 and a first connecting rod 41 and a second connecting rod 42 symmetrically distributed on both sides thereof. A mounting hole 400 is formed on the connecting portion 40, and an extension column 30 is formed on the horizontal blade 3. The mounting hole 400 is movably connected to the extension column 30; the upper hidden blade 20 is movably connected to the first connecting rod 41, and the lower hidden blade 21 is movably connected to the second connecting rod 42.

[0047] like Figures 1 to 3 As shown, the track link 4 in the first embodiment is composed of a connecting portion 40, a first link 41 and a second link 42, and is designed in a W shape as a whole, wherein the extension column 30 is inserted into the mounting hole 400, so that the horizontal blade 3 can always rotate around the extension column 30 when rotating relative to the housing 1, which provides a guarantee for the smoothness and stability of the wind guide adjustment. Since the first link 41 and the second link 42 of the track link 4 are symmetrically distributed on both sides of the connecting portion 40, when the connecting portion 40 moves downward with the rotation of the horizontal blade 3, the first link 41 ( Figure 4 The second connecting rod 42 and the lower hidden blade 21 generate relative movement, so that the lower hidden blade 21 continues to be close to the bottom wall of the air outlet channel 10; similarly, when the connecting portion 40 moves upward with the rotation of the horizontal blade 3, the second connecting rod 42 is driven to move upward, and finally the required downward blowing function is completed after the lower hidden blade 21 swings toward the inside of the air outlet channel 10. The two situations are exactly the opposite. The independent action of the connecting rod on each side is utilized to ensure that the hidden blade on the other side can stably remain in place while adjusting the airflow action, thereby changing the direction and distribution of the airflow, and achieving the blowing effect achieved by using multiple horizontal blades 3 in the prior art, providing users with a more comfortable environmental experience.

[0048] One end of the upper hidden blade 20 and the lower hidden blade 21 are both provided with a connecting shaft 220, and the other end are both provided with a snap-fit ​​block 221. The connecting shaft 220 is movably connected in the shell 1, and the first connecting rod 41 and the second connecting rod 42 are both provided with an arc-shaped slide groove 430, and the snap-fit ​​block 221 is movably snap-fitted in the arc-shaped slide groove 430.

[0049] Preferably, if Figures 1 to 3 As shown, the track link 4 in the first embodiment adopts a unilateral structural design in the air outlet channel 10 to save the space layout of the entire housing 1. It is worth noting that the connecting shaft 220 in the first embodiment also adopts a symmetrical design along the length direction on the upper / lower hidden blades 21, and the engaging block 221 only needs to correspond to the position where the track link 4 is to be installed. Figure 3 As shown, when the above-mentioned horizontal blade 3 rotates around its axis (the axis is the extension column 30), the upper / lower hidden blade 21 can be driven to swing around its respective rotation center (the rotation center is the axis line of the connecting shaft 220) into the air outlet channel 10 through the first connecting rod 41 or the second connecting rod 42. It can be seen that the connecting shaft 220 provides a stable rotation center, and the cooperation between the locking block 221 and the arc-shaped slide groove 430 ensures the precise control and smooth switching of the upper / lower hidden blade 21 between different positions. This structure not only simplifies the assembly process, but also optimizes the direction and distribution of the airflow, improves the ventilation efficiency, effectively avoids direct blowing to a specific area, and provides a more comfortable environmental experience.

[0050] Further preferably, continue to refer to Figure 3 In the first embodiment, a soft rubber sleeve 221a is connected to the engaging block 221. During the movement of the first connecting rod 41 / the second connecting rod 42, on the one hand, the arc-shaped slide groove 430 is used to allow the engaging block 221 to slide freely inside it, thereby ensuring that the blade can move smoothly from one position to another; on the other hand, the soft rubber sleeve 221a and the arc-shaped slide groove 430 (which are arranged in a stepped shape as a whole, refer to Figure 3 ) The smooth contact of the inner wall can reduce the possibility of direct contact between mechanical parts, and can also effectively avoid the collision between the track link 4 and the upper / lower hidden blade 21 when the horizontal blade 3 fluctuates up and down, thereby extending the service life and ensuring the working environment of the air outlet structure during operation.

[0051] The first connecting rod 41 and the second connecting rod 42 are both formed with a clearance groove 431, and the upper and lower sides of the shell 1 are both formed with an avoidance groove 11. The clearance groove 431 can provide a rotation space for the upper / lower hidden blades 21; the first connecting rod 41 and the second connecting rod 42 can movably penetrate the avoidance groove 11.

[0052] More preferably, if Figures 3 to 5 As shown, since the movement of the first connecting rod 41 and the second connecting rod 42 is achieved by driving the connecting portion 40 by the rotation of the horizontal blade 3, the design of the recess 431 provides additional rotation space for the upper / lower hidden blade 21, which greatly guarantees the operating range and flexibility, and ensures that the upper / lower hidden blade 21 can cooperate with the horizontal blade 3 within the required range to assist in blowing, thereby making the blowing direction more accurate and stable (see Figure 4 and Figure 5 Blowing posture), effectively preventing the upper / lower hidden blades 21 from failing to achieve the desired blowing effect due to position interference with the auxiliary connecting rod, thereby ensuring the comfort of the user's blowing experience.

[0053] A rotating shaft 31 and a track block 32 are respectively disposed on both sides of the horizontal blade 3 . A connecting hole 12 and an arc track groove 13 are opened on the shell 1 . The rotating shaft 31 is rotatably disposed in the connecting hole 12 , and the track block 32 is movably engaged with the arc track groove 13 .

[0054] like Figure 3As shown, the rotating shaft 31 in the first embodiment is distributed on both sides of the horizontal blade 3 as the rotation center. Since the track link 4 in the first embodiment is only provided at one place to save space, a track block 32 is also provided on the side of the horizontal blade 3 away from the track link 4. When the user manually rotates the horizontal blade 3, the rotating shaft 31 rotates in the connecting hole 12, driving the horizontal blade 3 to swing along the set direction. At the same time, the track block 32 slides along the arc track groove 13, which not only limits the range of motion of the horizontal blade 3, but also provides a precise guiding effect. As the angle of the horizontal blade 3 changes, the track link 4 (the first link 41 and the second link 42) also stops or swings accordingly, thereby driving the movement of the upper / lower hidden blade 21. It can be seen that under the complementary cooperation of the rotating shaft 31 and the arc track groove 13, unnecessary shaking or deviation is reduced, and the overall stability of the structure is improved. At the same time, it also effectively avoids direct friction between the horizontal blade 3 and other components during the rotation process, reduces the risk of wear, and prolongs the service life.

[0055] Embodiment 2:

[0056] The present scheme also includes an adjusting member 5 which is movably arranged and runs through the width direction of the horizontal blade 3, and an adjusting plate 50 which is located outside the horizontal blade 3 is movably connected to the adjusting member 5. A plurality of air guide blades 14 which are located in the air outlet channel 10 are movably arranged in the shell 1, and the adjusting plate 50 is movably connected to the air guide blade 14 in the middle position; when the adjusting member 5 moves along the length direction of the horizontal blade 3, the adjusting plate 50 can drive the plurality of air guide blades 14 to swing synchronously in the air outlet channel 10; when the adjusting member 5 drives the horizontal blade 3 to rotate, the adjusting plate 50 rotates relative to the horizontal blade 3 without driving the plurality of air guide blades 14 to move.

[0057] like Figures 4 to 7 As shown, the second embodiment is improved on the basis of the first embodiment. It is worth noting that the adjusting member 5 is integrally movably arranged in the horizontal blade 3, and the end away from the adjusting plate 50 extends out of the housing 1, so that the user can adjust the air outlet direction of the horizontal blade 3, which provides convenience. When the adjusting member 5 drives the horizontal blade 3 to rotate around the axis of the rotating shaft 31, there is no relative movement between the adjusting member 5 and the horizontal blade 3; Figure 6 During the movement of the horizontal blade 3 in the longitudinal direction, the adjusting member 5 can drive the adjusting plate 50 movably connected thereto to move, thereby driving the plurality of air guide blades 14 to swing left and right in the air outlet channel 10 to adjust the air outlet to the left and right. It should be noted that the plurality of air guide blades 14 in the second embodiment are assembled by a connecting plate 141 and two upper and lower fixing plates 140, wherein, as shown in FIG. Figure 6As shown, the upper and lower fixing plates 140 are used to limit the installation position of a plurality of air guide blades 14 in the shell 1. The fixing plates 140 can be connected to the shell 1 by screws, etc., and the connecting plate 141 is movably hinged to each air guide blade 14 to ensure that the plurality of air guide blades 14 can swing synchronously under the drive of the adjustment plate 50, thereby achieving overall adjustment of the airflow direction.

[0058] The adjusting member 5 also includes: a driving plate 51, a guide cavity 33 is opened in the middle position of the horizontal blade 3 along its length direction, the driving plate 51 is movably arranged in the guide cavity 33 and abuts against the horizontal blade 3; a connecting seat 52, one end of the adjusting plate 50 is movably connected to the connecting seat 52, and the other end is formed with a U-shaped groove 500 movably inserted in the wind guide blade 14, locking grooves 520 are symmetrically opened in the connecting seat 52, and a snap block 510 is formed at the end of the driving plate 51, and the snap block 510 is movably snapped into the locking groove 520.

[0059] Further, if Figure 6 and Figure 7 As shown, a part of the driving plate 51 in the second embodiment moves in the guide cavity 33, and the other part extends out of the horizontal blade 3. In this way, when the user applies a rotational force to the driving plate 51, the force can be directly transmitted to the horizontal blade 3, and finally the horizontal blade 3 changes the main blowing direction. Since the U-shaped groove 500 on the adjustment plate 50 is movably inserted into the connecting column 142 (such as Figure 7 As shown), the hinge between the connecting seat 52 and the adjusting plate 50 does not affect the angle of the air guide blade 14 during the swinging of the horizontal blade 3; on the contrary, during the movement of the driving plate 51 in the guide cavity 33 along the length direction of the horizontal blade 3, the adjusting plate 50 can be driven to swing synchronously through the connecting seat 52. At this time, the cooperation between the U-shaped groove 500 and the connecting column 142 can be used to drive several air guide blades 14 to swing synchronously, thereby achieving the adjustment of the air outlet angle of the air guide blade 14, and the swinging of the horizontal blade 3 in the air outlet channel 10, plus the auxiliary blowing effect of the upper / lower hidden blades 21, greatly improves the comfort of the user's blowing experience. Preferably, this embodiment can also be provided with a damper (not shown in the figure) in the driving plate 51 to control its left and right sliding operation force.

[0060] More preferably, if Figure 6 to Figure 7As shown, the buckle block 510 and the locking groove 520 in the second embodiment of the present invention are movably connected to each other, which enables quick installation and removal between the two, provides convenience for subsequent maintenance and replacement, and also extends the service life of the air outlet structure. In addition, the connecting seat 52 in the second embodiment of the present invention also has a part of its structure movably connected to the guide cavity 33, and utilizes the limiting effect of the guide cavity 33 to ensure the smoothness and accuracy of the reciprocating movement of the adjustment plate 50 driven by the connecting seat 52. In addition, the second embodiment of the present invention is also provided with an anti-slip block 501 (such as Figure 7 As shown), the anti-detachment block 501 can effectively prevent the adjustment plate 50 from detaching from the connecting column 142, thereby ensuring the smoothness and stability of the two during relative activities and ensuring that the various components can work together smoothly and accurately.

[0061] The horizontal blade 3 is provided with a raised block 34 located at the opening periphery of the guide cavity 33 , and the end of the driving plate 51 away from the buckle block 510 is formed with a handle portion 511 , and a guide groove 511 a is formed in the handle portion 511 , and the guide groove 511 a is movably engaged with the raised block 34 .

[0062] More preferably, if Figure 7 As shown, the handle portion 511 is completely located on the outside of the horizontal blade 3, which is beneficial to increase the overall width of the horizontal blade 3, so that the user can indirectly adjust the inclination angle of the horizontal blade 3. In the process of adjusting the air guide blade 14 to guide the air left and right, the stability between the drive plate 51 and the horizontal blade 3 is enhanced through the close cooperation of the protrusion block 34 and the guide groove 511a, so that the two can work together smoothly and accurately, reducing the looseness or misalignment problems between components, thereby ensuring the precise movement of the drive plate 51 in the length direction of the horizontal blade 3, avoiding unnecessary deviation or shaking, and improving the operating accuracy of the air outlet structure.
