The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0035] The present application will be further described in detail below in combination with the drawings.

[0036] Please refer to Figures 1 to 14 The air purification device 100 with adjustable air direction provided by the first embodiment of the present application comprises a mounting seat 10, a filter element 20, an air outlet mechanism 30 and an air supply mechanism 40.

[0037] Please refer to Figures 1 to 5The air purification device 100 comprises a mounting base 10, a filter element 20, an air outlet mechanism 30 and an air supply mechanism 40. The mounting base 10 is provided with a lower air inlet 11. The filter element 20 is arranged in the mounting base 10 and is used to filter the air flow flowing from the lower air inlet 11. The air outlet mechanism 30 is arranged in the mounting base 10 and comprises an upper air outlet structure 31 and an air direction adjusting structure 32. The upper air outlet structure 31 is provided with an upper air outlet 33. The air direction adjusting structure 32 is movably connected to the upper air outlet structure 31 so as to be capable of exposing or shielding the upper air outlet 33. When the upper air outlet 33 is exposed, the air flow can flow out from the upper air outlet 33 in a direction of the upper air outlet 33. When the upper air outlet 33 is shielded, the air flow can flow out from the upper air outlet 33 and then change the flow direction. The air supply mechanism 40 is arranged in the mounting base 10 and is used to deliver the air flow filtered by the filter element 20 to the air outlet mechanism 30 so as to be capable of flowing out through the air outlet mechanism 30.

[0038] The air purification device 100 can adjust the flow direction of the air flow. The mounting base 10 is used to mount the filter element 20, the air outlet mechanism 30 and the air supply mechanism 40. The filter element 20 is used to filter the air flow. The air supply mechanism 40 is used to deliver the air flow. The air flow finally flows through the air outlet mechanism 30 and then flows out through the air outlet mechanism 30. When the air outlet mechanism 30 is used to blow air, the air flow can flow out from the upper air outlet 33 of the upper air outlet structure 31 or can flow out from the upper air outlet 33 and then change the flow direction. Thus, the flow direction of the air flow can be adjusted, for example, the air flow can flow downward or can flow sideward. Therefore, the air direction adjusting structure 32 can be used to adjust the flow direction of the air flow so as to make the air flow have different flow directions and improve the practicability of the air purification device 100.

[0039] The upper air outlet 33 of the air purification device 100 is located below the lower air inlet 11 when the air purification device 100 is in use. The air flow flows into the lower air inlet 11 located below and then flows out from the upper air outlet 33 located above. The upper air outlet 33 can be vertically directed upward, can be directed sideward or can be directed downward. In this embodiment, the upper air outlet 33 is vertically directed upward. The air direction adjusting structure 32 can be rotatably or slidably movably connected to the upper air outlet structure 31 so as to shield or expose the upper air outlet 33.

[0040] When the upper air outlet 33 is shielded or exposed by rotating, the air adjusting structure 32 can be arranged on the top of the upper air outlet structure 31, so as to shield or expose the upper air outlet 33 by the shielding structure when rotating relative to the upper air outlet structure 31, or rotate the air adjusting structure 32 to the side of the mounting base 10 to expose the upper air outlet 33, and rotate the air adjusting structure 32 to the top of the mounting base 10 to shield the upper air outlet 33; by sliding, the upper air outlet 33 can be shielded or exposed by horizontally sliding relative to the mounting base 10, so as to adjust the air flow direction of the upper air outlet 33.

[0041] Specifically, referring to Figure 3 and Figure 5 , the upper air outlet 33 of the embodiment blows air in an upward direction, and the air adjusting structure 32 is arranged on the top of the upper air outlet structure 31, and rotates relative to the upper air outlet structure 31 to adjust the air flow direction of the upper air outlet 33. Specifically, the air flow is adjusted to flow out of the upper air outlet 33 and then flow to the side.

[0042] Referring to Figures 2 to 4 , Figure 6 and Figure 12 and Figure 13 , in an embodiment of the application, the air adjusting structure 32 comprises an air adjusting cover 321, the air adjusting cover 321 is connected to the upper air outlet structure 31 to rotate, and the air adjusting cover 321 is provided with a side air outlet 324. When the air adjusting cover 321 is rotated to shield the upper air outlet 33, the air flow of the upper air outlet 33 flows through the air adjusting cover 321 and then flows out of the side air outlet 324, so that when the air flow direction of the upper air outlet structure 31 is not needed to be adjusted, the position of the air adjusting cover 321 is rotated to expose the upper air outlet 33, so that the air flow can directly flow vertically upward along the upper air outlet 33; when the air flow direction of the upper air outlet structure 31 is needed to be adjusted, the air adjusting cover 321 is rotated to shield the upper air outlet 33, at this time, the air flow of the upper air outlet 33 impacts on the air adjusting cover 321, the air flow direction is reversed, and the air flow flows out of the side air outlet 324 on the air adjusting cover 321.

[0043] Specifically, referring to Figure 12 and Figure 13The air adjusting cover 321 comprises an outer supporting ring 3211, two first side walls 3212 oppositely arranged, a second side wall 3213 and a top wall 3214. The outer supporting ring 3211 has a gap 3215, the second side wall 3213 and the gap 3215 are oppositely arranged, the two first side walls 3212 are arranged on opposite sides of the gap 3215, and the top wall 3214 is connected to the top of the first side wall 3212 and the second side wall 3213. The side air outlet 324 is formed by the first side wall 3212 and the second side wall 3213. The outer supporting ring 3211 is used to rotate relative to the upper air outlet structure 31, so as to adjust the direction of the gap 3215, that is, the direction of the side air outlet 324 can be adjusted.

[0044] Further, since the upper air outlet 33 is upward, the air flow flows upward and hits the top wall 3214. In order to reduce the flow resistance of the air flow, the top wall 3214 of the side air outlet 324 of the embodiment is inclined upward away from the direction of the upper air outlet 33. At this time, the air flow hits the top wall 3214 and changes the flow direction of the air flow. The upward inclination of the top wall 3214 can reduce the resistance of the air flow, so that the air flow can maintain a larger flow rate as much as possible. At the same time, the upward inclination of the top wall 3214 can reduce the noise generated when the air flow hits the top wall 3214.

[0045] Specifically, the inclination angle of the top wall 3214 relative to the plane of the upper air outlet 33 is between 6-10°. In this way, the air flow can finally flow out to the side, and the size of the air flow flowing to the side is not changed too much. The inclination angle of the top wall 3214 relative to the plane of the upper air outlet 33 can be 6°, 7°, 8°, 9° and 10°, and is not limited herein.

[0046] Specifically, the inclination angle of the top wall 3214 relative to the plane of the upper air outlet 33 in the embodiment is 8°. When the air flow flows out from the upper air outlet 33, the effect of reducing the air resistance and the noise can be achieved, and the effect of changing the flow direction of the air flow flowing to the side is not changed too much.

[0047] Further, please refer to Figure 2 and Figure 6 and Figure 14, in order to facilitate the use of the user, the air adjusting structure 32 further comprises a first mounting frame 322 and a first driving motor 323, the first mounting frame 322 is connected to the upper air outlet structure 31 or the mounting seat 10, specifically, it is connected to the upper air outlet structure 31, so that it can rotate under the driving of the upper air outlet structure 31, the first mounting frame 322 is used for installing the first driving motor 323, the first driving motor 323 is used for driving the air adjusting cover 321 to rotate, so as to cover above the upper air outlet 33 or away from the upper air outlet 33, in this way, by setting the first driving motor 323, the flow direction of the air flow can be adjusted in an automatic manner, so as to adjust the upper air outlet and the side air outlet, compared with the manual mode, it is convenient for the user to use.

[0048] Please refer to Figure 2 、 Figure 6 and Figures 9 to 11 , in an embodiment of the present application, the air adjusting structure 32 is used for adjusting the air flow flowing out of the upper air outlet 33 to flow out along the side, the upper air outlet structure 31 comprises an air outlet cover 311, the air outlet cover 311 has the upper air outlet 33, the air outlet cover 311 is rotatably connected relative to the mounting seat 10 and is used for rotating the air adjusting structure 32, so as to drive the air adjusting structure 32 to rotate relative to the mounting seat 10, in this way, by setting the air outlet cover 311, the upper air outlet 33 with the required shape, such as circular, square and the like, can be arranged on the air outlet cover 311 according to the air outlet condition, and by setting the air outlet cover 311, the air adjusting structure 32 can rotate; at the same time, by setting the air outlet cover 311 for the air adjusting structure 32 to rotate, the air adjusting structure 32 can be driven to rotate relative to the mounting seat 10, when the air adjusting structure 32 is shielded at the position of the upper air outlet 33, by driving the rotation of the air adjusting structure 32, since the air adjusting structure 32 adjusts the air flow to flow out along the side at this time, that is, the flow direction of the air flow during the side air outlet is adjusted, that is, the air outlet range of the whole air purifying device 100 is adjusted, the air outlet can be rotated within 360 degrees.

[0049] Specifically, please refer to Figure 9 and Figure 10 , the air outlet cover 311 of the embodiment comprises a base plate 3111 and an air guide cylinder 3112 arranged on the base plate 3111, the air guide cylinder 3112 has the upper air outlet 33, the cross-sectional area of the air guide cylinder 3112 gradually decreases in the direction away from the air supply mechanism 40, in this way, when the air flow is sent from the air supply mechanism 40, the air flow is guided and concentrated by the air guide cylinder 3112, and finally flows out through the upper air outlet 33 after concentration, so that the air flow can have a greater flow rate at the upper air outlet 33 after concentration.

[0050] Among them, the air outlet cover 311 further comprises a support frame 3113, the support frame 3113 is connected to the base plate 3111 and is coaxially arranged with the base plate 3111, and is used for rotating the air adjusting structure 32.

[0051] Further, in order to facilitate the adjustment of the air outlet range when the air purification device 100 is in the side air outlet state, the air outlet cover 311 comprises two air ducts 3112 arranged at an angle of 180°; the air adjusting cover 321 in the air adjusting structure 32 is provided with two side air outlets 324, one of which is used for the air flow flowing out of one air duct 3112. Thus, when the air adjusting cover 321 is shielded above the upper air outlet 33 to perform side air outlet and the range of side air outlet needs to be adjusted, only 180 degrees of the air outlet cover 311 needs to be rotated, and 90 degrees of the air adjusting cover 321 needs to be rotated, so that the two side air outlets 324 can be rotated together by 360 degrees, realizing the adjustment of 360 degrees of side air outlet, thereby facilitating the adjustment of the air outlet direction of the air purification device 100.

[0052] Further, please refer to Figure 2 , Figure 6 and Figure 11 , in order to facilitate the user's adjustment, the upper air outlet structure 31 comprises a second mounting bracket 312 and a second driving motor 313, the second mounting bracket 312 is connected to the mounting seat 10 and is used to install the second driving motor 313, so as to drive the air outlet cover 311 to rotate through the second driving motor 313, that is, when the air outlet coverage range needs to be adjusted in the side air outlet mode, the air outlet cover 311 is driven to rotate through the second driving motor 313, and the air adjusting cover 321 is also driven to rotate, so as to automatically adjust the coverage range when the side air outlet.

[0053] Among them, the first driving motor 323 and the second driving motor 313 of the embodiment are both step motors.

[0054] Please refer to Figures 1 to 5 and 7, the mounting seat 10 comprises a base 12 and a side frame 13, the side frame 13 is provided with a lower air inlet 11, and the lower air inlet 11 is arranged at one end of the side frame 13 close to the base 12, so that the base 12 serves as a support basis, the air inlet is arranged at the side of the side frame 13 and close to the base 12, compared with the way of arranging the air inlet towards the ground on the base 12, when the air is sent through the air sending mechanism 40, the air flow can enter from the side, realizing a larger range of air inlet, which can absorb impurities from a larger ground range, at the same time, it can adapt to the filtration of large-sized impurities, for example, for animal hair impurities, since the animal hair has a large size when it is in a group, the size of the lower air inlet 11 can be set to be larger, so that the hair in a group and with a large size can enter the lower air inlet 11 to be filtered by the filter element 20.

[0055] Among them, please refer to Figure 7 and Figure 8The height H of the lower air inlet 11 is greater than or equal to 6 mm in the axial direction of the side frame 13, and the upper end of the lower air inlet 11 is lower than the bottom of the air blowing mechanism 40. Since the minimum diameter of the hair ball is generally greater than or equal to 6 mm, in order to enable the hair ball to enter from the lower air inlet 11, the height of the lower air inlet 11 is set to be greater than or equal to 6 mm. In addition, in order to ensure that the air flow can be sent out from the upper air outlet 33 after the impurities such as hair are sucked into the air blowing mechanism 40 from the lower air inlet 11, the upper end of the lower air inlet 11 is lower than the bottom of the air blowing mechanism 40.

[0056] Further, in order to ensure the suction force of the air blowing mechanism 40, the height of the lower air inlet 11 in the embodiment ranges from 6 mm to 20 mm. By limiting the height of the lower air inlet 11 within this range, the suction force of the air blowing mechanism 40 at the lower air inlet 11 can be ensured, and the flow rate of the air flow at the lower air inlet 11 can be ensured. For example, the height of the lower air inlet 11 can be 6 mm, 7 mm, 8 mm, 18 mm, 19 mm, 20 mm, or the like according to the power of the air blowing mechanism 40, which is not limited herein.

[0057] Referring to Figure 8 , in order to ensure the suction force of the air blowing mechanism 40, the distance D between the filter element 20 and the side frame 13 is greater than or equal to 6 mm, that is, the diameter of the hair ball is generally 6 mm. By setting the distance between the filter element 20 and the side frame 13 to the minimum value, the hair can be sucked into the filter element 20, and the hair ball can be prevented from being clamped between the side frame 13 and the filter element 20.

[0058] Further, in order to ensure the suction force of the air blowing mechanism 40, the distance D between the filter element 20 and the side frame 13 ranges from 6 mm to 15 mm. Since the space in the shell body of the side frame 13 is an air blowing channel, by setting the distance between the filter element 20 and the side frame 13 within this range, there is a range value between the shell body of the side frame 13 and the filter element 20, and the air blowing channel between the two has a value size, which ensures the suction force of the air blowing mechanism 40 in the air blowing channel. For example, the distance D between the filter element 20 and the side frame 13 can be 6 mm, 7 mm, 8 mm, 10 mm, 12 mm, 15 mm, or the like according to the power of the air blowing mechanism 40, which is not limited herein.

[0059] Further, referring to Figure 2 and Figure 6 , in order to realize the installation of the air blowing mechanism 40, the mounting seat 10 further comprises a connecting seat 14 and an air guide cover 15. The connecting seat 14 is arranged at the top of the filter element 20 and is used to install the air blowing mechanism 40. The air guide cover 15 is arranged around the air blowing mechanism 40 and is connected between the side frame 13 and the connecting seat 14, so as to mount the connecting seat 14 on the side frame 13.

[0060] In addition, in order to protect the air outlet mechanism 30, the air purification device 100 further comprises a protective cover 50, which is arranged above the air outlet mechanism 30, and the protective cover 50 is provided with an air outlet hole 51. By arranging the protective cover 50, the air outlet mechanism 30 and the air supply mechanism 40 can be preliminarily protected, and large-particle impurities are prevented from falling into the air outlet mechanism 30 and the air supply mechanism 40.

[0061] Please refer to Figure 2 and Figure 7 The air supply mechanism 40 of the embodiment comprises a third driving motor 41 and an impeller 42. The third driving motor 41 is mounted on the seat 14 of the side frame 13 and is used to provide driving force for the rotation of the impeller 42. The third driving motor 41 has an output shaft, and the impeller 42 is mounted on the output shaft of the third driving motor 41. Under the driving of the third driving motor 41, the impeller 42 drives the air to rotate, so that the air enters the air purification device 100 through the lower air inlet 11, and the filtered air is discharged through the upper air outlet 33.

[0062] Among them, the third driving motor 41 of the embodiment can be a direct current motor or an alternating current motor, which is not limited here; the impeller 42 can be a mixed flow fan. Since the specific speed of the mixed flow fan is greater than that of the axial flow fan, the mixed flow fan can provide greater air pressure, thereby improving the flow force of the air flow.

[0063] Further, please refer to Figure 13 and Figure 14 Since the rotation angle of the air adjusting cover 321 driven by the first driving motor 323 is 90 degrees, the air adjusting cover 321 is provided with a first limiting column 3216, and the first mounting frame 322 is provided with a first limiting bone 3221. In the control program, the first driving motor 323 is given a signal to stop when it collides with an obstacle. When the first limiting column 3216 of the air adjusting cover 321 rotates in the first mounting frame 322 and collides with the first limiting bone 3221 on the first mounting frame 322, the movement is stopped. In this way, the switching between upward air outlet and side air outlet is realized. When it is necessary to switch the air outlet direction again, the first driving motor 323 is released once again.

[0064] Similarly, please refer to Figure 10 and Figure 11Since the rotation angle of the air outlet shroud 311 driven by the second driving motor 313 is 180 degrees, the air outlet shroud 311 is provided with a second limiting column 3114, and the second mounting frame 312 is provided with a second limiting bone 3121. A signal is given to the second driving motor 313 in the control program to stop when the second limiting column 3114 on the air outlet shroud 311 rotates in the second mounting frame 312 and collides with the second limiting bone 3121 on the second mounting frame 312. When the second limiting column 3114 on the air outlet shroud 311 rotates in the second mounting frame 312 and collides with the second limiting bone 3121 on the second mounting frame 312, the movement in this direction is stopped and the reverse rotation is started. In this way, the reciprocating 180° rotation of the air outlet shroud 311 is realized, and the air outlet shroud 311 and the air regulating shroud 321 move together to realize the reciprocating 180° rotation. When the air regulating shroud 321 is arranged above the air outlet shroud 311, the 360° side air outlet is realized.

[0065] In the air purification device 100 of the embodiment, the air outlet adjusting mode is as follows:

[0066] (1) When the first driving motor 323 and the second driving motor 313 are not working, the default state is the upward air outlet state through the upper air outlet 33 of the air outlet shroud 311.

[0067] (2) When the air outlet direction needs to be adjusted, the second driving motor 313 drives the air regulating shroud 321 to rotate 90 degrees and then stops. At this time, the upward vertical air outlet state is switched to the side air outlet state.

[0068] (3) When the side air outlet state needs to be adjusted to the upward vertical air outlet state, the second driving motor 313 drives the air regulating shroud 321 to rotate back 90 degrees.

[0069] (4) When the air outlet state is the side air outlet state, the second driving motor 313 drives the air outlet shroud 311 to rotate the air regulating shroud 321 by 180 degrees. At this time, the air outlet mode changes to the 360° side air outlet mode. After the air outlet mode is ended, the first driving motor 323 rotates back 90 degrees to restore the upward air outlet state.

[0070] Please refer to Figure 15 The air purification device 100 provided by the second embodiment of the present application is basically the same as the first embodiment. The difference is that:

[0071] The upper air outlet structure 31 comprises an air outlet cover 311 which is rotationally connected relative to the mounting side frame 13, and the air direction adjusting structure 32 comprises an air direction adjusting cover 321 which is rotationally connected relative to the air outlet cover 311. When it is necessary to adjust the air direction or the air outlet range, the air outlet cover 311 and / or the air direction adjusting cover 321 are manually rotated to achieve the air direction adjusting effect. That is, the air purification device 100 with adjustable air direction in the embodiment reduces the first driving motor 323 and the second driving motor 313, reduces the driving source, can have lower production cost, and users can select to purchase the air purification device 100 with driving or without driving according to their own needs.

[0072] The technical means disclosed in the present application scheme is not limited to the technical means disclosed in the above-mentioned embodiments, but also includes the technical scheme composed of any combination of the above technical features. It should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can also be made, which are considered as the protection scope of the present application.
