[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The present invention provides an air outlet device, which includes: a main body including a first housing and a second housing that are buckled together; the first housing is provided with a first limiting groove, and the second housing is provided with a second limiting groove at a position corresponding to the first limiting groove; a turntable disposed in the installation space formed by surrounding the first housing and the second housing; a first end portion of the turntable is embedded in the first limiting groove, and a second end portion of the turntable corresponding to the first side is embedded in the second limiting groove, and the first limiting groove and the second limiting groove clamp the turntable.

[0025] With such a setting, the turntable and the first housing and the second housing can be fixed without screws. The turntable can be directly limited by the mutual cooperation of the limiting groove and the structure of the turntable itself, so that the first housing and the second housing clamp the turntable through the first limiting groove and the second limiting groove, thereby avoiding shaking between the turntable and the first housing and the second housing, solving the problem of generating noise during rotation, and improving the user experience. In addition, the working hours of screwing are saved, the efficiency is improved, and the production cost of using screws is reduced. Moreover, when the user assembles by himself, the number of parts is reduced, which is also convenient for the user to assemble by himself.

[0026] 2. The present invention provides an embodiment in which a first convex edge and a second convex edge are provided and their lengths are different. With such a setting, the structure of the turntable can be simplified, and it is not necessary for the entire edge of the turntable to be embedded in the limiting groove. At the same time, the length setting of the limiting groove can be reduced, which is beneficial to reducing the use of production materials. Since the lengths of the first convex edge and the second convex edge are different, it can play a certain anti-misassembly role.

[0027] 3. The present invention provides an embodiment in which the edge is installed in clearance fit with the limiting groove. With such a setting, the stability between the turntable and the limiting groove can be enhanced, ensuring that the first limiting groove and the second limiting groove can clamp the turntable, thereby avoiding shaking between the turntable and the first housing and the second housing, solving the problem of generating noise during rotation, and improving the user experience.

[0028] 4. The present invention provides a number of positioning holes on the turntable, and a first support pillar is provided on the first housing and / or the second housing. With such a setting, through the cooperation between the positioning holes and the first support pillar, the fixing relationship between the turntable and the first housing and the second housing is strengthened, thereby further enhancing the stability between the turntable and the limiting groove.

[0029] 5. By providing an annular frustum on the base and a circular hole adapted to embed the annular frustum in the present invention, the power cord of the air outlet device can pass through the center of the base, and then the power cord can be smoothly led out by utilizing the structure of the base. Such an intermediate wire-passing structure can solve the problem of the power cord being pulled due to the stretching during the rotation process, and the problem of the power cord being worn due to friction with the turntable on the base.

[0030] 6. By providing an arc-shaped hole on the base and a second support pillar on the turntable in the present invention, the movement range of the turntable is restricted, so that the turntable can reciprocally rotate within a certain range, preventing the turntable from making an endless circular motion when the air outlet device malfunctions during rotation.

[0031] 7. By providing a slider or a fixing piece on the second support pillar in the present invention, the turntable and the base can be integrated, preventing the two from separating when the air outlet device is working. Moreover, the slider or the fixing piece can ensure that while the turntable and the base are integrated, they can also ensure stable movement between the turntable and the base, reducing the friction force between the two.

[0032] 8. By circumferentially providing a first groove on the edge of the annular boss and providing a buffer member inside the first groove in the present invention, it can be ensured that when the turntable rotates relative to the base, the noise generated by the vibration between the two can be reduced, thereby being able to maintain low-noise movement and improving the user experience.

[0064] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0065] Among the household appliances such as air conditioners, electric heaters, air cooler fans, and electric fans sold on the market currently, some drive the main body of the household appliance to rotate through a crank connecting rod mechanism, thereby achieving the purpose of air sweeping. The crank connecting rod mechanism is generally connected to a turntable in the base of the household appliance, and the turntable is fixed together with the main body of the household appliance. Therefore, when air sweeping, the first housing 1 and the second housing 2 of the main body rotate simultaneously with the turntable. During use, there will be situations such as shaking and unstable installation between the turntable 3 and the first housing 1 and the second housing 2, and thus noise will be generated during rotation, affecting the user experience. An air outlet device provided in an embodiment of the present invention is used to overcome the problem that the existing turntable 3 is not fastened to the first housing 1 and the second housing 2, is prone to shaking, and noise will be generated during rotation.

[0066] As Figures 1 to 20 shown, an embodiment of the present invention provides an air outlet device, which includes: a main body 5 and a turntable 3. The main body 5 includes a first housing 1 and a second housing 2 that are fastened together. The first housing 1 is provided with a first limiting groove 12, and the second housing 2 is provided with a second limiting groove 21. The position where the second limiting groove 21 is provided is a position corresponding to the first limiting groove 12. A connecting structure is provided on the first housing 1 and the second housing 2, and the first housing 1 and the second housing 2 are connected into one body through the connecting structure. The connecting structure can be a screw post provided on the first housing 1 and the second housing 2. For example, the first housing 1 is provided with a first screw post, and the second housing 2 is provided with a second screw post. After the first housing 1 and the second housing 2 align the screw posts, screws can be driven in for connection. The turntable 3 is arranged in the installation space formed by enclosing the first housing 1 and the second housing 2. The first end of the turntable 3 is embedded in the first limiting groove 12, and the second end of the turntable 3 is embedded in the second limiting groove 21.

[0067] Of course, the first housing 1 and the second housing 2 can also be fastened by connection methods such as snap-fitting, which are not limited in this embodiment. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0068] When installing the turntable 3, the first housing 1, and the second housing 2, first insert the first end of the turntable 3 into the first limiting groove 12, and then insert the second end into the second limiting groove 21. At the same time, align and insert the first screw post and the second screw post of the first housing 1 and the second housing 2. After the first housing 1 and the second housing 2 are fixed by screws, the turntable 3 is also fixed in the first housing 1 and the second housing 2. The first limiting groove 12 and the second limiting groove 21 can completely clamp the turntable 3 to prevent the turntable 3 from shaking with the first housing 1 and the second housing 2.

[0069] With such a setting, the turntable 3 can be fixed to the first housing 1 and the second housing 2 without using screws. It can be directly limited by the mutual cooperation between the limiting grooves and the self-structure of the turntable 3, so that the first housing 1 and the second housing 2 clamp the turntable 3 through the first limiting groove 12 and the second limiting groove 21, thus avoiding shaking between the turntable 3 and the first housing 1 and the second housing 2, solving the problem of generating noise during rotation, and improving the user experience. Moreover, the working hours of screwing are saved, the efficiency is improved, and the production cost of using screws is reduced. In addition, when the user assembles by himself, the number of parts is reduced, which also facilitates the user's self-assembly.

[0070] The first end and the second end can be set at opposite positions of the turntable 3. Those skilled in the art can also adjust the positions of the first end and the second end according to the actual situation. The first end and the first limiting groove 12 are installed with a clearance fit, and the second end and the second limiting groove 21 are installed with a clearance fit. With such a setting, the stability between the turntable 3 and the limiting grooves can be strengthened, ensuring that the first limiting groove 12 and the second limiting groove 21 can clamp the turntable 3, thus avoiding shaking between the turntable 3 and the first housing 1 and the second housing 2, solving the problem of generating noise during rotation, and improving the user experience.

[0071] As Figure 2 and Figure 13 shown, the maximum value of the length of the overall size of the turntable 3 is L1, the maximum value of the width is L2, the distance between the two screw posts of the first housing 1 and the second housing 2 is L3, and the distance between the positions where the turntable 3 is buckled with the first housing 1 and the second housing 2 is L4. Since L3 > L1, there will be no interference between the length direction of the turntable 3 structure and the screw posts. In the width direction, since L2 > L4, the distance in the width direction of the turntable 3 can place itself into the installation space, and the turntable 3 can be fixed after the first housing 1 and the second housing 2 are assembled.

[0072] As Figure 4 and Figure 13 shown, the length of the first convex edge 33 is A1, the length of the second convex edge 34 is A2, and the thickness is the same as the thickness h of the entire turntable 3. The inner length of the limiting groove of the first housing 1 is A3 and the height is H. Since H > h and A3 > A1, the first convex edge 33 can be placed into the limiting groove of the first housing 1 and can drive the first housing 1 to rotate when rotating.

[0073] As Figure 7 and Figure 13As shown, and because the inner length of the limiting groove of the second housing 2 is A4 and the height is also H, where H > h and A4 > A2, the second convex edge 34 can be placed into the limiting groove of the second housing 2 and can drive the second housing 2 to rotate when rotating. When the first housing 1 and the second housing 2 are fitted together, the first housing 1, the second housing 2, and the turntable 3 can rotate as a whole along with the turntable 3 to achieve the purpose of shaking the head.

[0074] In this embodiment, as Figure 3 , Figure 6 and Figure 12 shown, a part of the first end of the turntable 3 extends outward to form a first convex edge 33, and the first convex edge 33 is embedded in the first limiting groove 12. A part of the second end of the turntable 3 extends outward to form a second convex edge 34, and the second convex edge 34 is embedded in the second limiting groove 21. The length of the first convex edge 33 is greater than or less than the length of the second convex edge 34. To ensure the stability of the turntable 3 during operation, the first convex edge 33 can be arranged at the middle part of the first end, and the second convex edge 34 can be arranged at the middle part of the second convex edge 34.

[0075] Of course, to ensure the stability between the turntable 3 and the first limiting groove 12 and the second limiting groove 21, a rough structure that is not smooth can be provided at the contact parts of the first convex edge 33 and the second convex edge 34 with the limiting grooves, or a rubber part or other structures that increase friction can be provided.

[0076] With such an arrangement, the structure of the turntable 3 can be simplified, and it is not necessary for the entire edge of the turntable 3 to be embedded in the limiting groove. At the same time, the setting of the length of the limiting groove can be reduced, which is beneficial to reducing the use of production materials. Since the lengths of the first convex edge 33 and the second convex edge 34 are different, it can play a certain anti-misoperation role.

[0077] As another implementation manner, the first convex edge 33 and the second convex edge 34 can be arranged at other positions of the turntable 3, or the lengths of the first convex edge 33 and the second convex edge 34 can be set to be the same. This embodiment does not limit this, and those skilled in the art can change this according to the actual situation as long as the same technical effects can be achieved.

[0078] As a deformed implementation manner, as Figures 21 to 24 shown, the turntable 3 is further provided with a plurality of convex structures 37, and the first housing 1 and the second housing 2 are provided with receiving grooves suitable for the convex structures 37 to be embedded. And the convex structures 37 and the receiving grooves are in interference fit.

[0079] On this basis, as an optional implementation, a convex structure 37 can also be provided only below the first convex edge 33 of the turntable 3. Or only provided below the second convex edge 34. This implementation is only for illustration and does not limit the installation position of the convex structure 37. Those skilled in the art can change the installation position according to the actual situation as long as the same technical effect can be achieved.

[0080] In order to save production materials, the center of the convex structure 37 can also be made hollow, leaving only the surrounding support plates.

[0081] By providing the convex structure 37, the stability between the turntable 3 and the first housing 1 and the second housing 2 can be further enhanced, thereby preventing the turntable 3 from shaking between the first housing 1 and the second housing 2, solving the problem of noise generated during rotation, and improving the user experience.

[0082] As Figure 12 shown, the first housing 1 and the second housing 2 are provided with a number of first support columns 11, the turntable 3 is provided with a positioning plate 32 extending upward, and the positioning plate 32 is provided with a number of positioning holes 321 adapted for the first support columns 11 to be inserted. In this embodiment, the turntable 3 is only provided with one positioning plate 32, and the first housing 1 is only provided with the first support columns 11 that cooperate with the positioning plate 32. In this implementation, the positioning plate 32 formed with the positioning holes 321 can be an annular buckle.

[0083] As Figure 15 shown, the minimum length of the positioning hole 321 is B1, the height is B2, the diameter of the first support column 11 on the first housing 1 is B3, and the height of the center of the first support column 11 from the surface of the chassis is B4. Since B1 > B3 and B2 > B4 + B3 / 2, the first support column 11 can be inserted into the positioning hole 321 to limit the first one.

[0084] With this setting, through the cooperation between the positioning holes 321 of the positioning plate 32 and the first support columns 11, the fixing relationship between the turntable 3 and the first housing 1 and the second housing 2 is strengthened, thereby further enhancing the stability between the turntable 3 and the limiting groove.

[0085] Of course, in order to further strengthen the fixing relationship between the turntable 3 and the first housing 1 and the second housing 2, multiple positioning plates 32 can also be provided on the turntable 3, and the first housing 1 and the second housing 2 are provided with the first support columns 11 that cooperate with the positioning plates 32. This embodiment only gives examples of the number of the positioning plates 32 and the first support columns 11 and does not limit them. Those skilled in the art can change according to the actual situation.

[0086] Moreover, the positioning plate 32 can also be replaced with other structures for fixing the turntable 3 to the first housing 1 and the second housing 2, such as a snap structure.

[0087] As Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 14 shown, the air outlet device further includes a base 4, a turntable 3 is arranged on the base 4, the base 4 is provided with an annular frustum 42, and the turntable 3 is provided with a circular hole 35 adapted to embed the annular frustum 42. The outer diameter of the annular frustum 42 is smaller than the inner diameter of the circular hole 35. A wire clip 44 is further arranged at the bottom of the base 4, and the wire clip 44 is used to fix the conductor on the base 4. With such a setting, the power cord of the air outlet device can be fixed on the wire clip 44, then pass through the annular frustum 42 at the center of the base 4, and then smoothly lead out by using the structure of the base 4. The power cord passes through the middle and is fixed via the wire clip 44, so it will not contact the inner wall of the annular frustum 42, and thus there will be no problem of wire abrasion.

[0088] In this way, the middle annular frustum 42 and the wire clip 44 can solve the problem of pulling on the power cord caused by the expansion and contraction of the power cord during the rotation process, as well as the problem of wire abrasion caused by the friction of the power cord following the turntable 3 on the base 4.

[0089] As Figure 9 , Figure 10 and Figure 11 shown, arc-shaped holes 41 extending a preset length are arranged on both sides of the annular frustum 42, and a second support column extending into the arc-shaped holes 41 and adapted to extend into the arc-shaped holes 41 is arranged at the bottom of the turntable 3. With such a setting, the movement range of the turntable 3 can be restricted, so that the turntable 3 can reciprocally rotate within a certain range, preventing it from making an endless circular motion when the rotation of the air outlet device fails.

[0090] Of course, the extension length of the arc-shaped holes 41 is related to the rotation angle of the air outlet device, and those skilled in the art can adjust the length of the arc-shaped holes 41 according to the actual situation of the air outlet device. The length of the arc-shaped holes 41 is not limited in this embodiment.

[0091] As Figure 11 and Figure 14 shown, a fixing piece 31 is arranged at one end of the second support column extending into the arc-shaped hole 41. The surface of the fixing piece 31 has a smooth structure, or a lubricating oil is applied between the end face of the fixing piece 31 close to the second support column and the base 4. The fixing piece 31 and the second support column are connected by screws or a snap structure.

[0092] As another preferred embodiment, a slider is provided at one end of the second pillar extending into the arc-shaped hole 41, and the slider and the second pillar are connected by the structure of a screw hole and a screw. The second pillar is provided with a screw hole, and a screw is provided on the end face of the slider close to the second pillar. The base 4 is provided with a chute suitable for the slider to slide, and the chute is arranged along the radial direction of the base 4 at at least one side position of the arc-shaped hole 41.

[0093] With such a setting, the turntable 3 and the base 4 can be integrated to prevent the two from separating during the operation of the air outlet device. Moreover, the slider or the fixing piece 31 can ensure that while the turntable 3 and the base 4 are integrated, the turntable 3 and the base 4 can still move stably, reducing the friction between the two.

[0094] As Figure 9 and Figure 10 , a circular boss 43 is circumferentially arranged on the edge of the base 4, the circular boss 43 is suitable for supporting the rotation of the turntable 3, and a first groove 431 is circumferentially arranged on the edge of the circular boss 43, and a buffer member is arranged inside the first groove 431. The buffer member can be a silica gel member or a rubber member, or other components that play a role in buffering and vibration reduction.

[0095] With such a setting, it can be ensured that when the turntable 3 rotates relative to the base 4, the noise generated by the vibration between the two can be reduced, so as to maintain low-noise movement and improve the user experience.

[0096] As Figure 21 shown, fixing pieces 38 are arranged on both sides of the turntable 3, and a second groove 381 suitable for the first screw post or the second screw post to be embedded is arranged on the fixing piece 38. A screw hole suitable for a screw to pass through is opened in the second groove 381. When installing the turntable 3, the first housing 1 and the second housing 2, the screw sequentially passes through the first screw post, the screw hole of the fixing piece 38 and the second screw post, thereby fixing the first housing 1, the second housing 2 and the turntable 3 together.

[0097] In this way, the stability between the turntable 3 and the first housing 1 and the second housing 2 is further enhanced, thereby avoiding shaking between the turntable 3 and the first housing 1 and the second housing 2, solving the problem of generating noise during the rotation process, and improving the user experience.

[0098] Of course, this embodiment is only an example. The fixing piece 38 can also be set to other quantities, and those skilled in the art can change the quantity of the fixing piece 38 according to the actual situation as long as the same technical effect can be achieved.

[0099] A bottom plate is further arranged at the bottom of the base 4 for closing the bottom of the base 4.

[0100] In this embodiment, a motor 6 is provided on one side of the turntable 3 at the circular hole 35, and the turntable 3 is provided with a rotating hole 36 suitable for the driving shaft of the motor 6 to extend out.
