Description

Technical Field

[0001] This application relates to the field of air purifiers for pets, and in particular to an air purifier for pets with increased air intake. Background Technology

[0002] Air purifiers are products that can adsorb, decompose, or transform various air pollutants, effectively improving air cleanliness. They are generally household and commercial air purifiers designed to remove indoor air pollution. Especially for people who keep pets such as cats and dogs, air purifiers need to remove not only air pollutants but also pet odors and pet hair, significantly increasing consumer demand for air purifier functionality.

[0003] Conventional air purifiers have insufficient air intake, making them ineffective at cleaning hair and odors, and therefore need improvement. Utility Model Content

[0004] In order to increase the air intake of an air purifier, this application provides an air purifier for pets with increased air intake.

[0005] This application provides a pet air purifier with increased air intake volume, employing the following technical solution:

[0006] An air purifier for pets with increased air intake includes a purifier body. The purifier body has an upper air inlet, a lower air inlet, and a main air inlet. The main air inlet is located on the front of the purifier body, and an air outlet is located on the back of the purifier body. A rectifier cavity is provided inside the purifier body. An upper airflow channel connected to the upper air inlet and a lower airflow channel connected to the lower air inlet are respectively provided above and below the rectifier cavity. An upper impeller is provided in the upper airflow channel, a lower impeller is provided in the lower airflow channel, and a main impeller is provided in the rectifier cavity. A drive assembly for driving the upper impeller, lower impeller, and main impeller to rotate is provided inside the purifier body.

[0007] By adopting the above technical solution, when the air purifier is working, a negative pressure is formed inside the purifier. Air enters the purifier body through the upper air inlet, lower air inlet, and main air inlet, increasing the air intake volume compared to traditional air purifiers with only one air inlet. The drive assembly drives the upper and lower impellers to rotate counterclockwise, drawing air from the upper and lower air inlets into the upper and lower airflow channels, respectively, and then into the main impeller from above and below. Simultaneously, the drive assembly drives the main impeller to rotate clockwise. The clockwise rotation of the main impeller throws the airflow inside the main impeller into the rectifier cavity and guides the airflow within the rectifier cavity to rotate clockwise, ultimately exiting the purifier body through the air outlet. The arrangement of the upper, lower, and main impellers increases the air intake volume and reduces the impact of turbulence on the air intake volume.

[0008] Optionally, the drive assembly includes two active drive components respectively mounted on the upper impeller and the lower impeller, and an upper drive motor and a lower drive motor are provided in the purifier body. The upper drive motor and the lower drive motor are respectively connected to one active drive component. It also includes two linkage components mounted on the main impeller. The two linkage components are respectively located at both ends in the height direction of the main impeller, and each drive component is connected to one linkage component.

[0009] By adopting the above technical solution, the upper drive motor and the lower drive motor control the rotation of the upper impeller and the lower impeller respectively through an active drive component. The rotation of the upper impeller or the lower impeller alone can drive the main impeller to rotate through the linkage component, thereby realizing the adjustment of the air intake volume to meet the various usage needs of consumers.

[0010] Optionally, the active drive component includes a gear ring, a drive gear, and a driven gear. The gear ring is sleeved on the outer peripheral wall of the upper impeller and is located at the bottom in the height direction of the upper impeller. The top of the upper impeller is rotatably connected to the purifier body via a rotating shaft. Both the drive gear and the driven gear are rotatably connected to the purifier body. The outer peripheral wall of the gear ring is provided with teeth. The drive gear and the driven gear are located on both sides of the gear ring and mesh with the teeth of the gear ring. The drive gear is connected to the motor shaft of the upper drive motor, and the driven gear is connected to the linkage component.

[0011] Optionally, the linkage includes a frame, two opposing planetary gears, two opposing sun gears, an input shaft, and an output shaft. The input shaft is coaxially connected to the driven gear, and the end of the input shaft away from the driven gear is connected to one sun gear. The frame is mounted on the edge of the driven gear. The two planetary gears are rotatably connected to the frame. The output shaft is located below the input shaft, and the end of the output shaft is connected to another sun gear. The two sun gears and the two planetary gears mesh with each other. An output gear is mounted on the end of the output shaft away from the sun gear. A drive ring is mounted on the top of the main impeller, and teeth are provided on the peripheral wall of the drive ring. The output gear meshes with the teeth of the drive ring.

[0012] By adopting the above technical solution, the upper drive motor is started. The motor shaft of the upper drive motor rotates clockwise, driving the drive gear to rotate clockwise. The clockwise rotation of the drive gear drives the upper impeller to rotate counterclockwise, guiding the air entering from the upper air inlet into the upper airflow channel and then into the main impeller from above. The counterclockwise rotation of the upper impeller drives the driven gear to rotate clockwise. The clockwise rotation of the driven gear drives the frame, input shaft, and its sun gear to rotate clockwise. Under the differential speed adjustment of the planetary gears, the other sun gear rotates counterclockwise, and drives the output gear to rotate counterclockwise through the output shaft. The counterclockwise rotation of the output gear drives the drive ring to rotate clockwise, and the drive ring drives the main impeller to rotate clockwise.

[0013] Optionally, the rotational speed of the main wind turbine is greater than that of the upper wind turbine.

[0014] Optionally, the rectifier cavity includes an annular flow channel and a straight flow channel. The length direction of the straight flow channel is tangent to the edge of the annular flow channel. The annular flow channel is eccentrically located on the side away from the straight flow channel. The main impeller is eccentrically located inside the annular flow channel. The upper impeller, lower impeller, and main impeller are coaxially arranged along the height direction of the purifier body.

[0015] By adopting the above technical solution, the clockwise rotation of the main impeller throws the airflow inside the main impeller into the annular flow channel, and guides the airflow in the annular flow channel to rotate clockwise along the annular flow channel. When the clockwise rotating airflow in the annular flow channel passes through the straight flow channel, it enters the straight flow channel and leaves the purifier body through the air outlet. The eccentric setting of the annular flow channel gives the straight flow channel more space, increasing the air intake volume of the straight flow channel.

[0016] Optionally, both the upper and lower airflow channels are funnel-shaped, and the diameters of both the upper and lower airflow channels decrease towards the direction of the rectifying cavity.

[0017] By adopting the above technical solution, the airflow in the upper and lower airflow channels is guided into the rectification cavity.

[0018] Optionally, the main impeller includes an upper blade, a lower blade, an annular baffle, and two rims. The two rims are spaced apart along the height direction. The annular baffle is located in the middle of the circumference of the main impeller. The annular baffle divides the blades into upper blades and lower blades. The upper and lower ends of the upper blades and lower blades are fixedly connected to the annular baffle and the rims, respectively. The upper blades and lower blades extend in a spiral shape and in opposite directions.

[0019] By adopting the above technical solution, the upper blades guide the airflow blown in from the upper impeller to the annular flow channel, and the lower blades guide the airflow blown in from the lower impeller to the rectifier cavity, thereby increasing the air intake volume and improving the air purification efficiency.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When the air purifier is working, a negative pressure is created inside. Air enters the purifier body through the upper air inlet, lower air inlet, and main air inlet, increasing the air intake volume compared to traditional air purifiers with only one air inlet. The drive assembly drives the upper and lower impellers to rotate counterclockwise, drawing air from the upper and lower air inlets into the upper and lower airflow channels, respectively, and then into the main impeller from above and below. Simultaneously, the drive assembly drives the main impeller to rotate clockwise. This clockwise rotation of the main impeller both throws the airflow inside the main impeller into the rectifier cavity and guides the airflow within the rectifier cavity to rotate clockwise, ultimately exiting the purifier body through the air outlet. The arrangement of the upper, lower, and main impellers increases the air intake volume and reduces the impact of turbulence on the air intake volume.

[0022] 2. The upper drive motor and the lower drive motor control the rotation of the upper impeller and the lower impeller respectively through an active drive component. The rotation of the upper impeller or the lower impeller alone can drive the main impeller to rotate through the linkage component, so as to realize the adjustment of the air intake volume to meet the various usage needs of consumers;

[0023] 3. Start the upper drive motor. The motor shaft of the upper drive motor rotates clockwise, driving the drive gear to rotate clockwise. The clockwise rotation of the drive gear drives the upper impeller to rotate counterclockwise, guiding the air entering from the upper air inlet into the upper airflow channel and then into the main impeller from above. The counterclockwise rotation of the upper impeller drives the driven gear to rotate clockwise. The clockwise rotation of the driven gear drives the frame, input shaft, and its sun gear to rotate clockwise. Under the differential speed adjustment of the planetary gears, the other sun gear rotates counterclockwise, and drives the output gear to rotate counterclockwise through the output shaft. The counterclockwise rotation of the output gear drives the drive ring to rotate clockwise, and the drive ring drives the main impeller to rotate clockwise. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses an air purifier for pets with increased air intake volume. (See also...) Figure 1 and Figure 2 A pet air purifier with increased air intake includes a purifier body 1. The purifier body 1 is provided with an upper air inlet 11, a lower air inlet 12 and a main air inlet 13. The main air inlet 13 is located on the front of the purifier body 1, and an air outlet 14 is provided on the back of the purifier body 1.

[0032] Reference Figure 2 and Figure 3The purifier body 1 has a rectifying cavity 2 inside, which includes an annular flow channel 21 and a straight flow channel 22. The length direction of the straight flow channel 22 is tangent to the edge of the annular flow channel 21. The annular flow channel 21 is eccentrically located on the side away from the straight flow channel 22. The straight flow channel 22 is connected to the air outlet 14. Above and below the rectifying cavity 2 are respectively an upper airflow channel 15 connected to the upper air inlet 11 and a lower airflow channel 16 connected to the lower air inlet 12. Both the upper airflow channel 15 and the lower airflow channel 16 are funnel-shaped, and their diameters decrease towards the rectifying cavity 2.

[0033] Reference Figure 3 An upper impeller 3 is installed in the upper airflow channel 15, a lower impeller 4 is installed in the lower airflow channel 16, and a main impeller 5 is installed in the rectifier cavity 2. The main impeller 5 is eccentrically positioned in the annular flow channel 21. The upper impeller 3, lower impeller 4, and main impeller 5 are coaxially arranged along the height direction of the purifier body 1. A drive assembly for driving the rotation of the upper impeller 3, lower impeller 4, and main impeller 5 is installed inside the purifier body 1.

[0034] When the air purifier is working, a negative pressure is created inside. Air enters the purifier body 1 through the upper air inlet 11, lower air inlet 12, and main air inlet 13, increasing the air intake compared to a traditional air purifier with only one air inlet. The drive assembly drives the upper impeller 3 and lower impeller 4 to rotate counterclockwise, drawing the air entering from the upper air inlet 11 and lower air inlet 12 into the upper airflow channel 15 and lower airflow channel 16, respectively, and then into the main impeller 5 from the top and bottom. At the same time, the drive assembly drives the main impeller 5 to rotate clockwise. The clockwise rotation of the main impeller 5 throws the airflow inside the main impeller 5 into the annular flow channel 21, and also guides the airflow in the annular flow channel 21 to rotate clockwise along the annular flow channel 21. When the clockwise rotating airflow in the annular flow channel 21 passes through the straight flow channel 22, it enters the straight flow channel 22 and exits the purifier body 1 through the air outlet 14. The arrangement of the upper impeller 3, lower impeller 4 and main impeller 5 can increase the air intake volume and reduce the impact of turbulence on the air intake volume.

[0035] Reference Figure 3 and Figure 4 The drive assembly includes two active drive components 6 respectively mounted on the upper impeller 3 and the lower impeller 4. The purifier body 1 contains an upper drive motor 8 and a lower drive motor 9, each connected to one active drive component 6. Two linkage components 7 are mounted on the main impeller 5, located at opposite ends of the main impeller 5 in the height direction. Each drive component is connected to one linkage component 7.

[0036] The upper drive motor 8 and the lower drive motor 9 control the rotation of the upper impeller 3 and the lower impeller 4 respectively through an active drive component 6. The rotation of the upper impeller 3 or the lower impeller 4 alone can drive the main impeller 5 to rotate through the linkage component 7, thereby adjusting the air intake volume to meet various user needs.

[0037] Reference Figure 3 and Figure 4 The active drive component 6 includes a gear ring 61, which is sleeved on the outer peripheral wall of the upper impeller 3. The gear ring 61 is located at the bottom of the upper impeller 3 in the height direction, and teeth are provided on the outer peripheral wall of the gear ring 61. The top of the upper impeller 3 is rotatably connected to the purifier body 1 via a rotating shaft. An active gear 62 is rotatably connected to the purifier body 1 via a rotating shaft. The active gear 62 is connected to the motor shaft of the upper drive motor 8, and the active gear 62 meshes with the teeth of the gear ring 61. The motor shaft of the upper drive motor drives the gear ring 61 and the upper impeller 3 to rotate by driving the active gear 62 to rotate. A passive gear 63 is provided on the side of the upper impeller 3 away from the active gear 62. The passive gear 63 is rotatably connected to the purifier body 1 via a rotating shaft, and the passive gear 63 meshes with the teeth of the gear ring 61. The passive gear 63 is connected to the linkage component 7.

[0038] Reference Figure 4 and Figure 5 The linkage 7 includes a frame 71, which is mounted on the edge of the bottom wall of the driven gear 63. Two opposing planetary gears 72 are mounted on two opposite plates of the frame 71, and are rotatably connected to the frame 71 via shafts. Two opposing sun gears 73 are mounted on the two planetary gears 72, and mesh with each other. An input shaft 74 is coaxially connected to the driven gear 63. One end of the input shaft 74, away from the driven gear 63, is connected to one sun gear 73. An output shaft 75 is mounted on the other sun gear 73. An output gear 76 is mounted on the end of the output shaft 75, away from the sun gear 73. A drive ring 51 is mounted on the top of the main impeller 5, and teeth are provided on the peripheral wall of the drive ring 51. The output gear 76 meshes with the teeth of the drive ring 51.

[0039] When the upper drive motor 8 is started, its motor shaft rotates clockwise, driving the drive gear 62 to rotate clockwise. The clockwise rotation of the drive gear 62 drives the upper impeller 3 to rotate counterclockwise, guiding the air entering from the upper air inlet 11 into the upper airflow channel 15 and into the main impeller 5 from above. The counterclockwise rotation of the upper impeller 3 drives the driven gear 63 to rotate clockwise, which in turn drives the frame 71, input shaft 74, and its sun gear 73 to rotate clockwise. Under the differential speed adjustment of the planetary gear 72, the other sun gear 73 rotates counterclockwise, and through the output shaft 75, drives the output gear 76 to rotate counterclockwise. The counterclockwise rotation of the output gear 76 drives the drive ring 51 to rotate clockwise, which in turn drives the main impeller 5 to rotate clockwise.

[0040] In this design, the gear ratio between the drive ring 51 and the output gear 76 is greater than the gear ratio between the gear ring 61 and the drive gear 62. In actual use, the rotational speed of the main impeller 5 is greater than that of the upper impeller 3. The differential speed adjustment function of the planetary gear 72 can eliminate the influence caused by the inconsistent rotational speeds of the main impeller 5, the upper impeller 3, and the lower impeller 4. The operation of the upper drive motor or the lower drive motor alone will not affect the drive structure.

[0041] Reference Figure 3 and Figure 4 The main impeller 5 includes an upper blade 52, a lower blade 53, an annular baffle 54, and two rims 55. The two rims 55 are spaced apart along the height direction, and a drive ring is installed on the outer side of the rims 55. The annular baffle 54 is located in the middle of the circumference of the main impeller 5. The annular baffle 54 divides the blades into upper blades 52 and lower blades 53. The upper and lower ends of the upper blades 52 and lower blades 53 are fixedly connected to the annular baffle 54 and the rims 55, respectively. The upper blades 52 and lower blades 53 extend in a spiral shape and in opposite directions.

[0042] The upper blade 52 guides the airflow blown in from the upper impeller 3 into the annular flow channel 21, and the lower blade 53 guides the airflow blown in from the lower impeller 4 into the annular flow channel 21, thereby increasing the air intake and improving air purification efficiency.

[0043] The implementation principle of a pet air purifier with increased air intake volume according to an embodiment of this application is as follows: When the air purifier is working, a negative pressure is formed inside the air purifier, and air enters the purifier body 1 through the upper air inlet 11, the lower air inlet 12, and the main air inlet 13, increasing the air intake volume compared to a traditional air purifier with only one air inlet. The drive assembly drives the upper impeller 3 and the lower impeller 4 to rotate counterclockwise, drawing the air entering from the upper air inlet 11 and the lower air inlet 12 into the upper airflow channel 15 and the lower airflow channel 16, respectively, and then into the main impeller 5 from the top and bottom. At the same time, the drive assembly drives the main impeller 5 to rotate clockwise. The clockwise rotation of the main impeller 5 throws the airflow inside the main impeller 5 into the annular flow channel 21, and guides the airflow in the annular flow channel 21 to rotate clockwise along the annular flow channel 21. When the clockwise rotating airflow in the annular flow channel 21 passes through the straight flow channel 22, it enters the straight flow channel 22 and leaves the purifier body 1 through the air outlet 14. The arrangement of the upper impeller 3, lower impeller 4 and main impeller 5 can increase the air intake volume and reduce the impact of turbulence on the air intake volume.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
