[0035] Referring to FIGS. 1 to 4 , a filter assembly 100 provided in one embodiment of the present application includes a mounting bracket 10, a filter, and a drive assembly 30. The mounting bracket 10 is mounted on the air purifier 200, and the filter is detachably mounted on the mounting bracket 10. The drive assembly 30 is connected to the mounting bracket 10 in a transmission manner, and is configured to be able to drive the mounting bracket 10 to be pushed out of the air purifier 200 and / or to drive the mounting bracket 10 to be pushed into the air purifier 200.

[0036] It can be understood that the mounting bracket 10 can be movably assembled in the air purifier 200. Specifically, the mounting bracket 10 can be driven to be pushed inward into the air purifier 200, and can also be driven by the driving component 30 to be pushed out of the air purifier 200. When the mounting bracket 10 is in the air purifier 200, the filter screen on it is also in the air purifier 200 and can perform filtering work. When the mounting bracket 10 is outside the air purifier 200, the filter screen on it can be replaced by disassembly and assembly. Among them, most of the mounting bracket 10 is outside the shell 201 of the air purifier 200, which can be considered to be outside the air purifier 200.

[0037] The filter assembly 100 may further include an assembly frame 50 , which is installed or formed in the air purifier 200 . The mounting bracket 10 may be movably mounted on the assembly frame 50 and move along the assembly frame 50 to be pushed into or out of the air purifier 200 .

[0038] The filter can be, but is not limited to, a high-efficiency filter. The mounting bracket 10 can be arranged horizontally. The filter can be installed by directly placing it on the mounting bracket 10. The filter is naturally supported by the mounting bracket 10 under the action of gravity. When the filter needs to be replaced, it is only necessary to remove the original filter and place a new filter when the mounting bracket 10 is pushed out of the air purifier 200. In some other embodiments, the filter can also be detachably mounted on the mounting bracket 10 by means of snap connection, bonding, screw connection, etc.

[0039] The driving assembly 30 is used to drive the mounting bracket 10, and specifically can drive the mounting bracket 10 to be pushed out of the air purifier 200, or can drive the mounting bracket 10 to be received in the air purifier 200. In some other embodiments, the mounting bracket 10 can also be manually driven and received in the air purifier 200.

[0040] The filter assembly 100 is detachably mounted on the mounting bracket 10, and the mounting bracket 10 can be pushed out and in from the air purifier 200 under the drive of the driving assembly 30. In this way, when the filter needs to be replaced, the user only needs to push the mounting bracket 10 through the driving assembly 30 to remove the original filter and replace it with a new one, which is simpler and more convenient to operate, and helps to improve user experience and user satisfaction.

[0041] In some embodiments, the filter assembly 100 further includes an indicator, which can emit an indication signal.

[0042] The indication signal can be a signal such as sound, text, image, color, etc. that can be perceived and distinguished by the user. Specifically, the indicator can be configured to generate at least two different indication signals to represent different states of the filter. In addition, in some other embodiments, the indication signal can also be transmitted to a terminal device such as a mobile phone to be notified by the user.

[0043] Specifically, the indicator is configured to send out an indication signal for notifying the filter to be replaced when the cumulative working time of the filter reaches a set time. The indicator may be an indicator light, and may emit green light when the cumulative working time of the filter does not reach the set time, and may emit yellow light and flash when the cumulative working time of the filter reaches the set time. The set time may be the service life of the filter.

[0044] In this way, the user can know whether the filter needs to be replaced through the indicator. After the filter reaches the end of its service life, the user can receive an indication signal and replace the filter in time.

[0045] In some embodiments, the drive assembly 30 includes a motor 31, which is configured to be able to rotate forward and reverse, and drives the mounting bracket 10 to be pushed out of the air purifier 200 when rotating forward, and drives the mounting bracket 10 to be pushed into the air purifier 200 when reversing.

[0046] The motor 31 may be, but is not limited to, a stepping motor, and its forward rotation and reverse rotation are two opposite rotation directions, and accordingly generate a driving force to drive the mounting bracket 10 to be pushed outward and inward.

[0047] In this way, the motor 31 can automatically push the mounting bracket 10 in and out, meeting the needs of users, so that the mounting bracket 10 can be moved in and out without manual operation.

[0048] In some embodiments, the filter assembly 100 further includes an operating member, which is communicatively connected with the drive assembly 30 and is used to control the start and stop of the drive assembly 30 .

[0049] The operating member and the driving assembly 30 may be connected by a limited communication connection or a wireless communication connection. The user interacts with the filter assembly 100 through the operating member. After receiving the user's operation, the operating member generates a network change signal, thereby controlling the driving assembly 30 to perform the operation. Specifically, the network change signal is used to control the operation of the motor 31. The motor 31 rotates forward or reverse after receiving the network change success signal. The operating member can be configured to respond by double-clicking and generate a network change signal.

[0050] The operating element may be a touch screen, and an operable virtual button may be formed in the touch screen, and the operating element may be integrated with the indicator on the same display panel, and the indicator light may be integrated on the operating button. In some other embodiments, the operating element may also be a physical button, etc., which is not specifically limited here.

[0051] In this way, the user can control the driving assembly 30 to work by operating the operating member, thereby controlling the pushing in and pushing out of the mounting bracket 10 .

[0052] Please refer to Figures 5 to 8 together. In some embodiments, the driving assembly 30 further includes a roller 33, and the motor 31 is connected to the roller 33. The roller 33 contacts the mounting bracket 10 and is configured to push the mounting bracket 10 by rolling.

[0053] The roller 33 contacts the surface of the mounting bracket 10 and can roll under the drive of the motor 31 to push the mounting bracket 10 through friction.

[0054] In this way, the driving assembly 30 drives the mounting bracket 10 through the roller 33. The assembly relationship between the two is simple, and driving can be achieved by contact without forming a stable connection.

[0055] Furthermore, the mounting bracket 10 includes a frame body 11 and an anti-slip strip 13 , wherein the anti-slip strip 13 is disposed on the frame body 11 ; the roller 33 contacts the anti-slip strip 13 and rolls along the anti-slip strip 13 .

[0056] The anti-slip strip 13 may be, but is not limited to, an EVA (Ethylene-Vinyl Acetate Copolymer) cotton strip with adhesive backing and is bonded to the frame 11 .

[0057] The anti-slip strip 13 can enhance the friction between the roller 33 and the mounting bracket 10, reduce the probability of the roller 33 slipping on the surface of the mounting bracket 10, and enhance the driving reliability.

[0058] In some embodiments, the axial direction of the output shaft 311 of the motor 31 is arranged along a first direction (the X direction as shown in FIG. 5 ), and the driving assembly 30 further includes at least two driven gear shafts 35, and the axial directions of all the driven gear shafts 35 are arranged along a second direction (the Y direction as shown in FIG. 5 ) intersecting the first direction, and are transmission-connected to the output shaft 311. The rollers 33 are arranged on the driven gear shafts 35, and at least part of the driven gear shafts 35 are provided with at least two rollers 33 spaced apart in the second direction.

[0059] The first direction may be perpendicular to the second direction, all driven gear shafts 35 are parallel and spaced apart from each other, and the rollers 33 on all driven gear shafts 35 can provide support to the mounting bracket 10 at different positions while generating drive, which helps ensure stable assembly and driving of the mounting bracket 10.

[0060] Furthermore, the output shaft 311 of the motor 31 is provided with at least two bevel driving gears 3111 spaced apart in the first direction, the driven gear shaft 35 is provided with a bevel driven gear 351 , and the bevel driven gear 351 of each driven gear shaft 35 is meshed with one bevel driving gear 3111 .

[0061] The bevel driving gear 3111 on the output shaft 311 of the motor 31 is arranged in a one-to-one correspondence with the driven gear shaft 35 and the bevel driven gear 351 thereon. By means of the meshing of the bevel driving gear 3111 and the bevel driven gear 351, the motor 31 can simultaneously drive multiple driven gear shafts 35 to rotate, thereby smoothly driving the mounting bracket 10.

[0062] The above-mentioned filter assembly 100, according to the working condition of the whole machine, automatically identifies and prompts to replace the filter when the high-efficiency filter reaches its service life. At this time, the operation button on the display panel indicates a yellow light alarm, prompting that the filter needs to be replaced in time. The user can double-click the operation button to confirm the replacement, and the operation part transmits the instruction to the stepper motor. The drive shaft of the motor 31 rotates forward, the conical driving gear 3111 rotates clockwise, and the conical driven gear 351 meshing therewith starts to rotate synchronously, thereby driving the roller 33 to act on the mounting bracket 10. The rollers 33 are distributed laterally on the driven gear shaft 35. The filter assembly 100 includes a driven gear shaft 35, and each group of driven gear shafts 35 has two rollers 33 symmetrically distributed on the left and right. The contact between the mounting bracket 10 and the roller 33 is pasted with an EVA cotton strip with a backing adhesive to increase the rolling friction. The mounting bracket 10 is pushed outward under the drive of the roller 33. Take out the original filter and place a new filter. At this time, double-click the operation button again. After the motor 31 receives the screen changing success signal, the conical driving gear 3111 rotates counterclockwise, and the conical driven gear 351 meshing therewith starts to rotate synchronously, thereby driving the roller 33 to act on the mounting bracket 10, so that it is pushed inward under the friction force of the roller 33, and the screen changing is completed. At this time, the indicator light of the operation button shows green.

[0063] In this way, the filter assembly 100 is easy to change. First, the whole machine can identify the usage time of the filter, alarm in time and prompt to change the filter, realizing intelligence; secondly, when replacing the filter, the filter assembly is automatically pushed out and pushed in through the touch screen operation to realize automation.

[0064] The present application also provides an air purifier 200, comprising the above-mentioned filter assembly 100.

[0065] Furthermore, the air purifier 200 includes a shell 201, which is configured with an installation port, and the installation bracket 10 is pushed into and pushed out of the shell 201 from the installation port; the installation bracket 10 includes a cover 15, and the cover 15 is configured to block the installation port when the installation bracket 10 is received in the shell 201.

[0066] In this way, when the mounting bracket 10 is received in the air purifier 200, the cover 15 can just block the mounting opening to prevent air leakage.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
