Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1, an embodiment of the present invention provides an air outlet device, which includes a fixing base 10, an air outlet assembly 20 and a buffer portion. The air outlet assembly 20 has an air outlet, the air outlet assembly 20 is movably disposed on the fixing base 10, and the air outlet assembly 20 has an open position for opening the air outlet and a closed position for closing the air outlet relative to the fixing base 10. The air outlet is used for air outlet, and when the air outlet is needed, the air outlet assembly 20 can be moved to the open position to enable air outlet, and when the air outlet is not needed, the air outlet assembly 20 is moved to the closed position to prevent dust from entering. The buffer part can be arranged on the fixing seat 10, can also be arranged on the air outlet assembly 20, and can also be simultaneously arranged on the fixing seat 10 and the air outlet assembly 20. When the air outlet assembly 20 is at the closed position, the buffer portion can prevent the air outlet assembly 20 from directly contacting the fixing base 10.

In the technical solution of this embodiment, by arranging the buffer portion between the fixing seat 10 and the air outlet assembly 20, in the closing process of the air outlet assembly 20, the air outlet assembly 20 contacts with the buffer portion and cannot directly contact with the fixing seat 10, so as to avoid damage caused by collision between the two components. Therefore, through the technical scheme of the embodiment, the problem that an air outlet device in the prior art is easy to damage can be solved. Moreover, by avoiding the collision between the fixing base 10 and the air outlet assembly 20, the noise of the air outlet assembly 20 in the closing process is reduced. Through the technical scheme, the service life of the air outlet device is prolonged, and the comfort of a user using the air outlet device is improved.

The buffer part may be plate-shaped, strip-shaped or block-shaped. The buffer portion may be provided as an elastic material to play a role in gradually decreasing the moving speed of the air outlet assembly 20 when the air outlet assembly 20 descends, so that the buffer effect may be improved. Specifically, in the present embodiment, the buffer portion includes the elastic pad 30. As shown in fig. 2 and 3, the elastic pad 30 includes a fixing section 31 and a buffer section 32. The fixing section 31 is used for fixing the elastic pad 30 on the fixing base 10 or the air outlet assembly 20. The buffer section 32 is connected with the fixed section 31, and when the air outlet assembly 20 is at the closed position, the buffer section 32 is located between the air outlet assembly 20 and the fixed seat 10. The buffer portion may be connected to the fixing seat 10 or the fixing position of the air outlet assembly 20 by providing the fixing section 31. In the installation position of the elastic pad 30, the height of the upper part of the buffer section 32 is higher than that of the fixing seat 10, so that the buffer section 32 can be clamped between the air outlet assembly 20 and the fixing seat 10 when the air outlet assembly 20 descends, and the buffer section 32 and the fixing seat are prevented from being in direct contact. By arranging the buffer section 32 between the air outlet assembly 20 and the fixing seat 10, the effect of preventing the air outlet assembly 20 from contacting with the fixing seat 10 can be achieved, and the descending speed of the air outlet assembly 20 can be gradually slowed down.

The elastic pad 30 may be made of rubber, plastic, foam, or the like. In the present embodiment, the elastic pad 30 is provided as a rubber material. This can improve the cushioning effect of the elastic pad 30 and reduce the manufacturing cost of the elastic pad 30. Also, the elastic pad 30 may be made of a transparent or light-colored material, so that the elastic pad 30 can be more matched to surrounding components in terms of appearance. When the air outlet assembly 20 reaches the closing position, the elastic deformation of the elastic pad 30 is set within a reasonable range, so that the effects of buffering and damping can be achieved in the closing process, and the air outlet assembly 20 is prevented from being damaged due to overlarge elastic force. The elastic deformation amount may be set in the range of 0.2mm to 0.8mm, for example, the elastic deformation amount may be set to 0.5mm.

As shown in fig. 4, the fixing base 10 is provided with a connection hole 11, and the fixing section 31 of the elastic pad 30 includes a connection section 311 and a clamping section 312. The first end of the connection section 311 is connected to the buffer section 32, the second end of the connection section 311 is connected to the first end of the clamping section 312, and the cross-sectional area of the first end of the clamping section 312 is larger than the cross-sectional area of the second end of the connection section 311. The connecting section 311 is inserted into the connecting hole 11, and the clamping section 312 is clamped with the connecting hole 11 in a matching manner. Since the elastic pad 30 is made of an elastic material, the clamping section 312 can be inserted through the connection hole 11 by elastic deformation. When the elastic pad 30 is installed, the connection is completed by passing the clamping section 312 through the connection hole 11 and then passing the connection section 311 into the connection hole 11. Thus, after the connection section 311 is inserted into the connection hole 11, the axial displacement of the connection section 311 can be limited by the engagement of the clamping section 312 and the connection hole 11, so that the connection reliability is ensured, and the separation of the elastic pad 30 from the fixing base 10 is prevented. Moreover, the arrangement can facilitate the assembly of the elastic pad 30 and the fixing base 10. Further, the cross-sectional area of the buffer section 32 is larger than the cross-sectional area of the first end of the connecting section 311. In this way, the axial displacement of the connection section 311 can be restricted, thereby further improving the reliability of the connection of the elastic pad 30 with the fixing base 10.

Specifically, the diameter of the second end of the snap section 312 becomes progressively larger in a direction toward the first end of the snap section 312. When the clamping section 312 passes through the connecting hole 11, the small-diameter part firstly penetrates into the connecting hole 11, and then the part with gradually enlarged diameter gradually enters into the connecting hole 11, so that the clamping section 312 can conveniently pass through the connecting hole 11, and the convenience in assembling the elastic pad 30 and the fixing seat 10 is further improved. Also, the diameter of the end face of the second end may be set smaller than the diameter of the connection hole 11, so that the catching section 312 can more conveniently pass through the connection hole 11.

Moreover, a sinking platform 12 is disposed on a side of the fixing base 10 close to the clamping section 312, and a first end of the clamping section 312 is located in the sinking platform 12. The first end of the clamping section 312 is arranged in the sinking platform 12, so that interference between the clamping section 312 and other parts of the fixing base 10 can be avoided, and radial displacement of the clamping section 312 can be limited by the sinking platform 12, so that the connection strength of the elastic pad 30 can be improved.

In the present embodiment, the buffer section 32 has a groove 321 at a side near the connection section 311. By arranging the groove 321 on one side of the buffer section 32 close to the connecting section 311, the elastic deformation of the buffer section 32 can be improved, so that the air outlet assembly 20 can be better buffered and damped. And the side of the buffer section 32 near the air outlet assembly 20 can be arranged in an arch shape, so that the contact area of the air outlet assembly 20 and the buffer section 32 is gradually changed from small to large in the process of contacting the two, and the buffer and shock absorption effects are further improved.

Specifically, in the present embodiment, the groove 321 is an annular groove, and the annular groove is disposed along the periphery of the connection section 311. Providing the groove 321 as an annular groove may improve the structural strength of the elastic pad 30. Further, the elastic pad 30 may have the grooves 321 for buffering and damping at any angle in the circumferential direction, so that it may be used without being limited to a specific angle when the elastic pad 30 is mounted. The elastic pad 30 may be provided as a revolution body, which facilitates both the manufacture of the elastic pad 30 and the installation and use of the elastic pad 30.

In order to further enhance the convenience of installing the elastic pad 30, a hollow structure 313 is provided at an end of the fixing section 31 remote from the buffer section 32. By providing the hollow structure 313, the fixed section 31 can be made more easily elastically deformed in the diameter direction. Thus, when the fixing section 31 is inserted into the connection hole 11, the fixing section 31 is more easily contracted in the diameter direction, thereby facilitating insertion of the fixing section 31 into the connection hole 11. Also, the outer diameter of the connection section 311 may be set to be larger than the inner diameter of the connection hole 11, i.e., the connection section 311 and the connection hole 11 employ an interference fit. In this way, the connecting section 311 can maintain a certain tension after penetrating into the connecting hole 11, so that the connection between the elastic pad 30 and the fixing base 10 is more firm. The interference of the connection section 311 with the connection hole 11 may be set according to the size and material. The interference may be set in the range of 0.1mm to 0.5mm, for example, the interference may be set to 0.3mm.

As shown in fig. 5, the buffer portion includes a plurality of elastic pads 30, and the plurality of elastic pads 30 are symmetrically disposed about a center line of the air outlet device. By providing a plurality of elastic pads 30, the cushioning and shock absorbing effects on the air outlet assembly 20 can be improved. Moreover, the plurality of elastic pads 30 are symmetrically arranged with the center line of the air outlet device, and after the air outlet assembly 20 moves to the closed position, a uniform gap is formed between the air outlet assembly 20 and the fixing seat 10, so that the attractiveness of the air outlet device is improved.

As shown in fig. 5 and 6, the fixing base 10 has an annular structure, and the top of the fixing base 10 is an inclined plane, and the top of the fixing base 10 has a lowest point and a highest point which are oppositely arranged. The air outlet assembly 20 is provided with an inclined plane which is matched with the inclined plane at the top of the fixed seat 10. The buffer part further comprises a protrusion 40, the protrusion 40 is located at the highest point of the top of the fixing base 10, and the elastic pad 30 is located at one side of the top of the fixing base 10 away from the highest point. By setting the top of the fixing seat 10 to be an inclined plane, the aesthetic degree of the air outlet device can be improved. The bump 40 is disposed at the highest point of the top of the fixing base 10, and can be contacted with the bump 40 during the descending process of the air outlet assembly 20, so as to prevent the air outlet assembly 20 from contacting with the fixing base 10, and thus, damage caused by collision between the two components can be avoided. The protrusion 40 located at the upper position of the fixing base 10 and the elastic pad 30 located at the lower position of the fixing base 10 cooperate to play a role in buffering and damping at different positions of the annular fixing base 10, thereby better protecting the air outlet device. In order to ensure the use effect of the buffer part and reduce the manufacturing cost of the device, two elastic pads 30 and a protrusion 40 can be arranged, the highest points of the three are positioned on the same plane, and the plane is matched with the top inclined plane of the fixing seat 10 and the inclined plane of the air outlet assembly 20.

Wherein the protrusions 40 may be separately processed and then mounted to the fixing base 10, and the protrusions 40 may be provided as an integral structure with the fixing base 10. Of course, the elastic pad 30 may be used instead of the protrusion 40 at the highest point of the top of the fixing base 10. In the present embodiment, the boss 40 is integrally formed with the fixing base 10, which facilitates the manufacture of the boss 40 and enables the size of the boss 40 to be reduced. The protrusions 40 may be provided on the fixing base 10 in a compact position, where the connection holes 11 are not properly provided or where the elastic pad 30 is not properly installed, to provide buffering and shock absorption effects.

Specifically, the fixing base 10 includes a support plate 13 and a decorative plate 14, and the decorative plate 14 is located inside the support plate 13. The air-out assembly 20 includes a decorative strip 21 and a lifting mechanism 22, the decorative strip 21 is disposed at the top end of the lifting mechanism 22, and a buffer portion is disposed between the decorative strip 14 and the decorative strip 21. The fixing base 10 is provided with the supporting plate 13 and the decorative plate 14, so that the structural strength of the device can be improved through the supporting plate 13, and the aesthetic degree of the device can be improved through the decorative plate 14. The air outlet assembly 20 is provided with the decorative strip 21 and the lifting mechanism 22, the opening or closing of the air outlet can be realized through the lifting and descending of the lifting mechanism 22, and the aesthetic degree of the device is improved through the decorative strip 21. Further, the cooperation of the decorative panel 14 and the decorative strip 21 can limit the lowering of the lifting mechanism 22. The decorative strip 21 and the decorative plate 14 are respectively provided with curved surfaces which are mutually matched, so that after the air outlet assembly 20 moves to the closed position, a small and uniform gap can be formed between the decorative strip 21 and the decorative plate 14, thereby improving the attractiveness of the air outlet device and preventing dust from entering. The buffer portion is provided between the decorative plate 14 and the decorative strip 21, and can prevent the decorative plate and the decorative strip from collision, thereby preventing damage, paint removal, noise and other problems caused by collision. The decorative panel 14 and the decorative strip 21 may be provided as plated pieces to further enhance the aesthetic appearance of the air outlet device.

Further, a buffer structure is provided between the support plate 13 and the decorative plate 14. During the descent of the air outlet assembly 20, the pressure applied to the decorative strip 14 by the decorative strip 21 can be transmitted to the support plate 13, i.e. the decorative strip 14 can press against the support plate 13, which can easily cause wear of the decorative strip 14 and the support plate 13 and can generate noise. By providing the buffer structure between the support plate 13 and the decorative plate 14, the decorative plate 14 and the support plate 13 can be prevented from being directly contacted or from being contacted with each other to play a role in buffering and damping, thereby reducing abrasion and noise. Therefore, the service life of the air outlet device and the comfort of a user using the air outlet device can be further improved by the arrangement. The buffer structure can be made of rubber or sponge and other materials, so that the use effect can be guaranteed, and the cost of the device can be reduced. Also, a buffering structure may be annularly provided between the support plate 13 and the decorative plate 14 to improve buffering and shock absorbing effects.

Another embodiment of the present invention provides an air conditioner, which has an air outlet device, wherein the air outlet device is the air outlet device provided in the foregoing embodiment. In the air conditioner, a buffer part is arranged between a fixing seat 10 of an air outlet device and an air outlet assembly 20. In this way, in the closing process of the air outlet assembly 20, the air outlet assembly 20 is in contact with the buffer part and cannot be in direct contact with the fixing seat 10, so that damage caused by collision of the air outlet assembly 20 and the buffer part can be avoided, and noise in the closing process of the air outlet assembly 20 can be reduced. Therefore, through the technical scheme of the embodiment, the service life of the air conditioner is prolonged, and the comfort of a user in using the air conditioner is improved.
