[0002] Some air outlet devices, such as air conditioners, fans, and bathroom heaters, have air outlet components that can rotate or swing in the air outlet of the shell, thereby increasing the diffusion range of the air flow, improving the air supply efficiency, and greatly improving the user experience.

[0003] In the related art, the tuyere assembly of the above-mentioned air outlet device usually has a rotating shaft, and the shell is provided with a mounting shaft near the air outlet, and the rotation of the tuyere assembly relative to the shell is achieved through the clearance between the rotating shaft and the mounting shaft. However, in order to ensure the smooth assembly of the rotating shaft and the mounting shaft, and to reduce the friction between the tuyere assembly and the shell when the tuyere assembly rotates, there is usually a certain gap between the tuyere assembly and the shell, which makes it easy for the tuyere assembly to shake axially during rotation, and may even deform axially and fall out of the mounting shaft.

DETAILED DESCRIPTION

[0084] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0085] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0086] The embodiment of the present application provides an air outlet device, which can be, for example, an air conditioner, a fan, a bathroom heater, etc. Figure 1 As shown, the air outlet device includes a panel 100, an air outlet assembly 200 and a fixing assembly 300; an air outlet 110 is provided on the panel 100; the air outlet assembly 200 is exposed from the air outlet 110; and the fixing assembly 300 is used to rotatably mount the air outlet assembly 200 on the panel 100.

[0087] Generally speaking, the housing of the air outlet device includes a panel 100 and a chassis 500. Figure 1 As shown, one side of the chassis 500 is open, and has a accommodating cavity inside, for accommodating multiple functional components of the air outlet device; the panel 100 is covered on the open side of the chassis 500, and an air outlet 110 is provided on the panel 100, and the air outlet 110 is connected to the accommodating cavity to allow the airflow generated inside the chassis 500 to be blown out therefrom.

[0088] The vent assembly 200 is located near the vent 110 of the air outlet device and is related to the air supply performance of the air outlet device, and the air supply performance may be, for example, air supply volume, air supply direction, air supply angle, etc. In one example, the vent assembly 200 may include an air guide installed in the vent 110 of the air outlet device, and the air guide is connected to the panel 100 based on the fixing assembly 300 provided in the embodiment of the present application, and can rotate relative to the panel 100. In another example, the vent assembly 200 may also include a mounting bracket, which is directly or indirectly connected to the housing of the air outlet device, wherein a portion of the air guide is located on the inner side of the mounting bracket, and the fixing assembly 300 provided in the embodiment of the present application is connected to the mounting bracket and can rotate relative to the mounting bracket; the mounting bracket is connected to the panel based on the fixing assembly 300 provided in the embodiment of the present application, and can rotate relative to the panel.

[0089] The air outlet device provided in the embodiment of the present application utilizes a fixing assembly 300 to rotatably mount the air outlet assembly 200 on the panel, and exposes the air outlet assembly 200 from the air outlet 110 of the panel. Compared with the arrangement method of mounting the air outlet assembly 200 on the chassis in the related art, the air outlet device provided in the embodiment of the present application reduces the occupation of the installation position and layout space in the chassis, can avoid affecting the air outlet volume and air intake volume of the air outlet device, and is conducive to realizing the rotation and sweeping of the air outlet assembly 200, ensuring a sufficiently large air supply range. Moreover, since the air outlet 110 is also arranged on the panel, the coaxiality and assembly convenience of the air outlet assembly 200 and the air outlet 110 are also improved, and the assembly error between the air outlet assembly 200 and the air outlet 110 is reduced.

[0090] In the related art, when the tuyere assembly 200 of some air outlet devices is installed in the housing, the tuyere assembly 200 is usually rotated relative to the housing by the clearance between the rotating shaft and the mounting axis. However, in order to ensure the smooth assembly of the rotating shaft and the mounting axis, and to reduce the friction between the tuyere assembly 200 and the housing when the tuyere assembly 200 rotates, there is usually a certain clearance between the tuyere assembly 200 and the housing, which makes it easy for the tuyere assembly 200 to shake axially during the rotation process, and may even deform axially and fall out of the mounting axis.

[0091] In some embodiments of the present application, Figure 2 As shown, the fixing assembly 300 includes an axle seat 1, a rotating shaft 2 and an anti-slipping member 3. The axle seat 1 and the rotating shaft 2 are connected to one and the other of the panel and the tuyere assembly 200, respectively. The axle seat 1 has an axial hole 11. The rotating shaft 2 is passed through the axial hole 11 and can rotate in the axial hole 11. The anti-slipping member 3 is connected to the rotating shaft 2 to prevent the rotating shaft 2 from axially slipping out of the axial hole 11. Therefore, in the embodiment of the present application, since the anti-slipping member 3 is provided on the rotating shaft 2, it is possible to prevent the rotating shaft 2 from slipping out of the axial hole 11 during the rotation of the tuyere assembly 200.

[0092] Alternatively, if Figure 3 As shown, the rotating shaft member 2 has a fixed end 24 and a free end 25 relative to each other, the fixed end 24 is connected to the panel or the air outlet assembly 200, and the free end 25 passes through the shaft hole 11; the anti-slip member 3 is located on the side of the shaft hole 11 away from the fixed end 24 of the rotating shaft member 2, and is detachably connected to the free end 25 of the rotating shaft member 2, wherein the orthographic projection of the anti-slip member 3 on the set plane has a portion located outside the orthographic projection of the shaft hole 11 on the set plane, and the set plane is perpendicular to the axis of the shaft hole 11.

[0093] Therefore, the anti-slip component 3 is located on the side of the shaft hole 11 which is axially away from the fixed end 24, and along the axial direction of the shaft hole 11, the projection of the anti-slip component 3 has a portion located outside the shaft hole 11, that is, the anti-slip component 3 cannot pass through the shaft hole 11 in the axial direction, so when the rotating shaft component 2 shakes axially or deforms axially in the shaft hole 11, the anti-slip component 3 will prevent the rotating shaft component 2 from falling out of the shaft hole 11, thereby significantly reducing or even eliminating the risk of the air outlet assembly 200 coming off the shaft when rotating.

[0094] In some embodiments of the present application, Figure 4 As shown, the anti-slip member 3 includes a first limiting portion 31 and a connecting portion 32, wherein the orthographic projection of the first limiting portion 31 on the set plane exceeds the boundary of the orthographic projection of the shaft hole 11 on the set plane; the connecting portion 32 is connected to the first limiting portion 31, and a first thread is arranged on the connecting portion 32; the free end 25 of the rotating shaft member 2 is provided with a second thread, and the second thread is opposite to and matches the first thread. Therefore, the anti-slip member 3 prevents the rotating shaft member 2 from slipping out of the shaft hole 11 through the first limiting portion 31, and realizes a detachable threaded connection with the rotating shaft member 2 through the connecting portion 32.

[0095] In a specific example, see Figure 4 A screw hole 251 is provided on the end face of the free end 25 of the rotating shaft 2, and the second thread is provided on the inner wall of the screw hole 251, that is, the rotating shaft 2 has an internal thread. The connecting portion 32 has a screw rod 321, and the first thread is provided on the outer wall of the screw rod 321, that is, the connecting portion 32 has an external thread. The first limiting portion 31 is a washer 311, and the washer 311 is sleeved on the screw rod 321. The screw rod 321 of the connecting portion 32 is screwed into the screw hole 251 of the rotating shaft 2, and the first limiting portion 31 is clamped between the connecting portion 32 and the rotating shaft. Optionally, the connecting portion 32 is a screw, and the washer 311 is clamped between the head of the screw and the shaft seat 1.

[0096] See also Figure 5In some embodiments, the shaft seat member 1 includes a shaft support 12 and a shaft seat cover body 13; the bottom of the shaft support 12 is connected to the panel 100, and a first mounting groove 121 is provided on the top of the shaft support 12; the shaft seat cover body 13 is detachably connected to the shaft support 12, and a second mounting groove 131 is provided on the shaft seat cover body 13, and the second mounting groove 131 cooperates with the first mounting groove 121 to form the shaft hole 11.

[0097] In this embodiment, the shaft seat component 1 is designed as a detachable structure, including a shaft support 12 and a shaft seat cover body 13; the shaft hole 11 is formed by a first mounting groove 121 formed on the shaft support 12 and a second mounting groove 131 formed on the shaft seat cover body 13, so when assembling the rotating shaft component 2 and the shaft seat component 1, the shaft seat cover body 13 can be removed first, and then the shaft body 21 can be inserted from the open side of the first mounting groove 121, and the positions of the first limiting portion 31 and the second limiting portion 22 can be adjusted so that they are respectively located on both sides of the shaft support 12; then the shaft seat cover body 13 is covered and connected to the shaft support 12 to lock the shaft body 21 in the shaft hole 11, thereby improving the convenience of assembly.

[0098] In some embodiments, Figure 6 As shown, the shaft support 12 includes a bottom plate 122, a first vertical plate 123 and a second vertical plate 124. The bottom plate 122 is connected to the mounting member 400. The first vertical plate 123 and the second vertical plate 124 are vertically arranged on the bottom plate 122 and are spaced apart along the axial direction of the shaft hole 11. The first vertical plate 123 is closer to the air outlet assembly 200 than the second vertical plate 124. A first sub-groove 1211 is provided on the side of the first vertical plate 123 away from the bottom plate 122, and a second sub-groove 1212 is provided on the side of the second vertical plate 124 away from the bottom plate 122. The first sub-groove 1211 and the second sub-groove 1212 constitute the first mounting groove 121.

[0099] By arranging the first vertical plate 123 and the second vertical plate 124 at intervals, and forming two shaft grooves, the first sub-groove 1211 and the second sub-groove 1212, respectively on the two vertical plates, the axial assembly of the rotating shaft 2 is reinforced. Specifically, since the first vertical plate 123 and the second vertical plate 124 are arranged at intervals and shaft grooves are respectively formed thereon, when the rotating shaft 2 located in the first installation groove 121 moves axially or deforms axially, the first vertical plate 123 and the second vertical plate 124 share the axial force of the rotating shaft 2, thereby improving the structural strength and anti-deformation ability of the shaft support 12.

[0100] In some embodiments of the present application, a reinforcing plate may be further provided between the first vertical plate 123 and the second vertical plate 124. The reinforcing plate is vertically connected to the first vertical plate 123 and the second vertical plate 124, so that it can support the first vertical plate 123 and the second vertical plate 124 in the axial direction of the shaft hole 11, thereby further enhancing the structural strength and anti-deformation ability of the shaft support 12.

[0101] Alternatively, if Figure 7 As shown, the thickness of the first vertical plate 123 is greater than the thickness of the second vertical plate 124 .

[0102] In some embodiments of the present application, see Figure 8 The shaft seat cover 13 includes a cover plate 132, a third vertical plate 133 and a fourth vertical plate 134. The third vertical plate 133 and the fourth vertical plate 134 are vertically arranged on the cover plate 132 and are spaced apart along the axial direction of the shaft hole 11. The third vertical plate 133 is closer to the air outlet assembly 200 than the fourth vertical plate 134. A third sub-groove 1311 is arranged on a side of the third vertical plate 133 away from the cover plate 132, and a fourth sub-groove 1312 is arranged on a side of the fourth vertical plate 134 away from the shaft hole 11. The third sub-groove 1311 and the fourth sub-groove 1312 constitute a second mounting groove 131.

[0103] By setting the third vertical plate 133 and the fourth vertical plate 134 at intervals, and forming the third sub-groove 1311 and the fourth sub-groove 1312 on the two vertical plates respectively, the axial assembly of the rotating shaft 2 is reinforced. Specifically, since the third vertical plate 133 and the fourth vertical plate 134 are set at intervals and have sub-grooves formed thereon respectively, when the rotating shaft 2 located in the third mounting groove moves axially or deforms axially, the third vertical plate 133 and the fourth vertical plate 134 share the axial force of the rotating shaft 2, thereby improving the structural strength and anti-deformation ability of the shaft seat cover 13, so that the shaft seat 1 formed by connecting the shaft seat cover 13 and the above-mentioned shaft support 12 has good structural strength and structural rigidity, is not easy to deform, and thus reduces the risk of the rotating shaft 2 coming out of the shaft hole 11.

[0104] In some embodiments of the present application, Figure 7 As shown, in the opening direction of the first mounting groove 121, the third vertical plate 133 and the first vertical plate 123 are opposite, and the third vertical plate 133 and the first vertical plate 123 are in contact or have a gap; the height of the fourth vertical plate 134 is greater than the height of the third vertical plate 133, and the side of the fourth vertical plate 134 away from the cover plate 132 is located between the first vertical plate 123 and the second vertical plate 124.

[0105] Based on this embodiment, the first vertical plate 123 (the third vertical plate 133), the fourth vertical plate 134 and the second vertical plate 124 are arranged in sequence in the axial direction of the shaft body 21, and the shaft body 21 is limited multiple times. On the one hand, it can prevent the shaft body 21 from radially escaping from the first mounting groove 121. On the other hand, it can also effectively prevent the shaft body 21 from axial deformation, further reducing the risk of de-axising when the air outlet assembly 200 rotates.

[0106] Alternatively, if Figure 7 As shown, the thickness of the fourth vertical plate 134 is greater than the thickness of the third vertical plate 133 .

[0107] In the embodiment of the present application, the shaft support 12 and the shaft seat cover 13 are detachably connected, and the detachable connection method can be, for example, connected by bolts or screws, or can be a snap-on connection.

[0108] In some embodiments, Figure 6 As shown, the shaft support 12 also includes a fixing portion 125, which is arranged on the bottom plate 122 and is located on the side of the second vertical plate 124 away from the first vertical plate 123. The fixing portion 125 is connected to or in contact with the plate surface of the second vertical plate 124, and the end of the fixing portion 125 away from the bottom plate 122 has a first mounting hole 1251; the cover plate 132 is provided with a second mounting hole 1321, and the second mounting hole 1321 is connected to the first mounting hole 1251; the shaft seat member 1 also includes a fastener 14, which is passed through the first mounting hole 1251 and the second mounting hole 1321 to connect the shaft support 12 and the shaft seat cover body 13.

[0109] Optionally, the fixing portion 125 can be a screw fixing seat, and the first mounting hole 1251 can be a screw mounting hole; the second mounting hole 1321 arranged on the cover plate 132 is a through hole, which can be, for example, a stepped hole, and the hole section with a larger aperture in the stepped hole is farther away from the second mounting hole 1321 than the hole section with a smaller aperture; the fastener 14 can be, for example, a screw, which passes through the stepped hole and is screwed into the screw mounting hole, wherein the head of the screw is located in the hole section with a larger aperture in the stepped hole.

[0110] In some embodiments of the present application, Figures 9 to 11 As shown, the rotating shaft 2 includes a shaft body 21 and a second limiting portion 22, and the shaft body 21 is located in the shaft hole 11; the second limiting portion 22 is located between the shaft seat 1 and the panel 100, or between the shaft seat 1 and the air outlet assembly 200, and the second limiting portion 22 circumferentially surrounds at least a portion of the shaft body 21; the orthographic projection of the second limiting portion 22 on the setting plane has a portion located outside the orthographic projection of the shaft hole 11 on the setting plane, and the setting plane is perpendicular to the axis of the shaft hole 11.

[0111] Therefore, in the fixing assembly 300 provided in the embodiment of the present application, the second limiting portion 22 and the first limiting portion 31 are respectively located on opposite sides of the axial hole 11 in the axial direction, and along the axial direction of the axial hole 11, the projection of the second limiting portion 22 and the projection of the first limiting portion 31 both have a portion located outside the axial hole 11, that is, neither the second limiting portion 22 nor the first limiting portion 31 fixed on the shaft body 21 can pass through the axial hole 11 in the axial direction, so that when the shaft body 21 shakes axially or deforms axially in the axial hole 11, the second limiting portion 22 will prevent the shaft body 21 from escaping from the outer side of the axial hole 11 (that is, the side away from the outer wall of the air outlet assembly 200), and the first limiting portion 31 will prevent the shaft body 21 from escaping from the inner side of the axial hole 11 (that is, the side facing the outer wall of the air outlet assembly 200), thereby significantly reducing or even eliminating the risk of the shaft coming off when the air outlet assembly 200 rotates.

[0112] The structure of the rotating shaft 2 provided in the embodiment of the present application can be selected or designed according to actual needs. For example, in some embodiments of the present application, Fig.12 As shown, the shaft body 21 is connected to the outer wall of the tuyere assembly 200, the second limit portion 22 is connected to the outer wall of the tuyere assembly 200, and in the axial direction of the shaft body 21, the length of the second limit portion 22 is less than the length of the shaft body 21. Alternatively, the shaft body 21 is connected to the panel 100, the second limit portion 22 is connected to the panel 100, and in the axial direction of the shaft body 21, the length of the second limit portion 22 is less than the length of the shaft body 21.

[0113] Optionally, the second limiting portion 22 may be connected to or in contact with the shaft body 21 , or a gap may exist between the second limiting portion 22 and the shaft body 21 .

[0114] In other embodiments of the present application, the shaft body 21 is connected to the outer wall of the tuyere assembly 200, the second stopper 22 is connected to the outer peripheral wall of the shaft body 21, and is spaced from the outer wall of the tuyere assembly 200, and the length of the second stopper 22 in the axial direction of the shaft body 21 is less than the length of the shaft body 21. Alternatively, the shaft body 21 is connected to the panel 100, the second stopper 22 is connected to the panel 100, and is spaced from the outer wall of the tuyere assembly 200, and the length of the second stopper 22 in the axial direction of the shaft body 21 is less than the length of the shaft body 21.

[0115] In other embodiments of the present application, the second limiting portion 22 is connected to the outer wall of the tuyere assembly 200, and the shaft 21 is connected to an end of the second limiting portion 22 away from the tuyere assembly 200. Alternatively, the second limiting portion 22 is connected to the panel 100, and the shaft 21 is connected to an end of the second limiting portion 22 away from the panel 100.

[0116] The embodiment of the present application does not impose any restriction on the connection relationship between the shaft body 21 and the second limiting portion 22, as long as it is ensured that when the shaft body 21 is located in the shaft hole 11, the second limiting portion 22 is located outside the shaft hole 11 and can be offset against the area on the shaft seat member 1 located at the edge of the shaft hole 11 to play a limiting role.

[0117] In some embodiments of the present application, Fig.14 and Fig.15 As shown, the rotating shaft 2 further includes at least two spherical crowns 221, which are arranged on the surface of the second limiting portion 22 facing the shaft seat 1, and the orthographic projection of the spherical crown 221 on the set plane is adjacent to or spaced from the orthographic projection of the shaft hole 11 on the set plane. Therefore, when the tuyere assembly 200 rotates and causes the rotating shaft 2 to shake or deform in the axial direction, the top of the spherical crown 221 can abut against the shaft seat 1, thereby preventing the shaft 21 from falling out of the shaft hole 11.

[0118] Fig.14 and Fig.15 Two possible positional relationships between the orthographic projection of the spherical cap 221 and the orthographic projection of the axial hole 11 on the set plane are shown. Fig.14 and Fig.15 In FIG. 1 , the outer edge of the orthographic projection of the axial hole 11 on the set plane is shown by a dotted line. Fig.14 As shown, on the set plane, there is a gap between the orthographic projection of the spherical cap 221 and the orthographic projection of the axial hole 11; Fig.15 As shown, on the set plane, the orthographic projection of the spherical cap 221 and the orthographic projection of the axial hole 11 are adjacent.

[0119] Since the surface of the spherical crown 221 facing the shaft seat member 1 is spherical, during the rotation of the tuyere assembly 200, the contact between the spherical crown 221 and the shaft seat member 1 is point contact, so the friction force generated is small, and the impact on the rotation of the tuyere assembly 200 is also relatively small, which is conducive to achieving precise control of the rotation of the tuyere assembly 200.

[0120] In some embodiments of the present application, Figures 12 to 15 As shown, the rotating shaft member 2 further includes at least two convex ribs 23, which are connected to the outer peripheral wall of the shaft body 21 and protrude in the radial direction of the shaft body 21. The at least two convex ribs 23 are spaced apart in the circumferential direction of the shaft body 21, and the second limiting portion 22 is located on the side of the convex rib 23 away from the shaft body 21. Exemplarily, when the number of the convex ribs 23 is two, the two convex ribs 23 are connected to opposite sides of the shaft body 21; when the number of the convex ribs 23 is more than two, the plurality of convex ribs 23 are equally spaced apart in the circumferential direction of the shaft body 21.

[0121] like Fig.14 and Fig.15As shown, when the shaft member 2 is matched with the shaft hole 11, at least two convex ribs 23 are also located in the shaft hole 11, and at least one of the at least two convex ribs 23 is in contact with the hole wall of the shaft hole 11. Compared with the solution in which the shaft body 21 is in direct contact with the inner wall of the shaft hole 11, in this solution, the top of the convex rib 23 is in contact with the inner wall of the shaft hole 11, so the contact area is reduced, and the friction force suffered by the shaft member 2 when rotating in the shaft hole 11 is further reduced.

[0122] In some embodiments of the present application, Fig. 20 As shown, the first end 231 of the convex rib 23 is connected to the outer wall of the tuyere assembly 200, and the second end 232 of the convex rib 23 extends along the axial direction of the shaft body 21 to the edge of the shaft body 21 away from the tuyere assembly 200, and the first end 231 and the second end 232 are opposite ends. Among them, the end surface of the second end 232 of the convex rib 23 is a slope 233, and the inclination direction of the slope 233 is that the farther away from the outer peripheral wall of the shaft hole 11, the closer to the outer wall of the tuyere assembly 200. In this way, the slope 233 can play a guiding role, making it easier for the shaft body 21 and the convex rib 23 to be inserted into the corresponding shaft hole 11.

[0123] In some embodiments of the present application, Figure 16 to Figure 17 As shown, the panel 100 includes a stacked face cover 120 and a mounting frame 130, the face cover 120 is provided with an air outlet 110, the mounting frame 130 is connected to the inner surface of the face cover 120, and the mounting frame 130 has a first opening 1301; the air outlet assembly 200 and the fixing assembly 300 are both located on the inner side of the first opening 1301, and the fixing assembly 300 is connected to the inner surface of the face cover 120.

[0124] In some embodiments of the present application, Figure 16 to Figure 17 As shown, an air intake gap 140 is formed between the inner surface of the cover 120 and the mounting frame 130; a second opening 1302 is formed on the mounting frame 130, and the second opening 1302 is used to allow the air flowing in from the air intake gap 140 to flow to the wind wheel of the air outlet device; the first opening 1301 and the second opening 1302 are spaced apart, and the first opening 1301 is not connected to the air intake gap 140.

[0125] In some embodiments of the present application, Fig.17 As shown, a first enclosure portion 1201 is provided on the inner surface of the face cover 120 around the air outlet 110, and a second enclosure portion 1303 is provided on the mounting frame 130 around the first opening 1301, and the first enclosure portion 1201 matches the second enclosure portion 1303, thereby forming an annular closed space between the first opening 1301, the first enclosure portion 1201, the second enclosure portion 1303 and the air outlet 110, and the annular space is isolated from the air intake gap 140.
