Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and particularly relates to a transmission mechanism and a cleaning equipment. Background Art

[0002] At present, after the cleaning equipment sucks dust, a large amount of garbage will accumulate in the dust cup of the cleaning equipment. After the garbage in the dust cup is removed, a large amount of dust will adhere to the filter component and / or the dust cup wall. If it is not cleaned in time, the accumulation of dust will affect the filtering performance. Therefore, it is necessary to clean the filter component.

[0003] For example, the Chinese utility model patent with the publication number CN209661520U discloses a dust cup of a vacuum cleaner with a filter element cleaning mechanism, which includes a dust cup and a filter element. The filter element is detachably installed in the dust cup. The filter element is arranged along the axis of the dust cup. A cleaning component is arranged between the inner wall of the dust cup and the outer wall of the filter element. The height direction of the cleaning component is parallel to the axis of the dust cup. The cleaning component extends along the circumferential direction of the dust cup at the same time. The cleaning component is fixedly connected to the inner wall of the dust cup. The cleaning end of the cleaning component extends towards the outer wall of the filter element. The utility model can achieve the purpose of cleaning the dust and garbage on the filter element, and the dust and garbage will not enter the external environment. However, it adopts a manual cleaning method during use, which is inconvenient to use and affects the user experience. Summary of the Utility Model

[0007] An induction element, which is arranged on one side of the transmission component and determines the position of the cleaning component by sensing the position of the transmission component;

[0008] An adsorption component, which is arranged between the transmission component and the cleaning component and is used to connect or disconnect the transmission component and the cleaning component;

[0009] A controller, which is respectively connected to the drive motor, the adsorption assembly and the sensing element to respectively control the opening and closing of the drive motor, the adsorption assembly and the sensing element. The drive mechanism controls the drive motor, the sensing element and the adsorption assembly through the controller, making the connection between the drive assembly and the cleaning assembly flexible, facilitating maintenance and replacement, and being able to provide a stable and controllable driving force to ensure the efficient operation of the cleaning assembly.

[0010] As an optional embodiment, the drive assembly includes:

[0011] A gear, which is arranged on the transmission shaft of the drive motor and can rotate when the drive motor starts;

[0012] A rack, which meshes with the gear and is adsorbed and connected to the cleaning assembly through the adsorption assembly. When the gear rotates and drives the rack to move, the rack drives the cleaning assembly to move along the filter assembly to clean the filter assembly and / or the dust cup. Through the meshing design of the gear and the rack, the linear movement of the cleaning assembly along the filter assembly is realized, improving the cleaning efficiency. And the compact design of the drive assembly reduces the space occupation and is convenient to be integrated into the cleaning device.

[0013] As an optional embodiment, the cleaning assembly includes a rod portion. A through hole is formed on one side of the dust cup away from the filter assembly. One end of the rod portion can move along the through hole and extend out of the dust cup. The adsorption assembly includes:

[0016] As an optional embodiment, the rack includes:

[0017] A vertical section, which has teeth and meshes with the gear;

[0018] A horizontal section, which is connected to the lower end of the vertical section and extends towards the dust cup and is located below the rod portion for installing the second magnet. Through the design of the vertical section and the horizontal section of the rack, the cleaning assembly can move along the vertical section, and the horizontal section provides an installation position for the second magnet, simplifying the structure.

[0019] As an alternative embodiment, an installation groove is formed in the horizontal section, and the second magnet is embedded in the installation groove and fixed in the installation groove by screws. The design of the installation groove provides a stable fixing method for the second magnet, improving the stability and durability of the structure.

The arrangement of the drive motor and the drive assembly optimizes the spatial layout and facilitates maintenance and operation. The arrangement position of the adsorption assembly makes the connection between the cleaning assembly and the rack more direct and stable.

[0021] As an alternative embodiment, the sensing element is arranged outside the dust cup and is arranged corresponding to the position of the upper end of the vertical section for sensing the position of the rack. The external arrangement of the sensing element facilitates monitoring the position of the rack and improves the accuracy of sensing.

[0022] As an alternative embodiment, when the drive assembly is in the first position, it can trigger the sensing element to generate a first sensing signal and send it to the controller. The controller receives the first sensing signal and can control the drive motor to rotate in the first direction and control the first magnet and the second magnet to attract each other, so that the drive assembly and the cleaning assembly are connected;

[0023] When the drive assembly moves from the first position to the second position, it triggers the sensing element to generate a second sensing signal and send it to the controller. When the drive motor rotates in the first direction to a preset angle, the controller controls the drive motor to rotate in the second direction so that the drive assembly moves to the first position;

[0024] When the drive assembly moves from the second position to the first position, it triggers the sensing element to generate the first sensing signal and send it to the controller. The controller receives the first sensing signal and controls the drive motor to turn off and controls the first magnet and the second magnet to disconnect, so that the drive assembly and the cleaning assembly are disconnected;

[0025] Wherein, when the drive assembly is in the first position, the cleaning assembly is located at the upper end of the filter assembly, and when the drive assembly is in the second position, the cleaning assembly is located at the lower end of the filter assembly. The triggering mechanism of the sensing element realizes precise control of the position of the drive assembly and improves the accuracy of the movement of the cleaning assembly.

Therefore, the specific structural and functional details applied herein are not intended to be limiting, but are only used as a basis for the claims and a representative basis for teaching those skilled in the art to use the present application in substantially any suitable detailed structure in a variety of ways.

[0074] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present application.

[0075] An object of an embodiment of the present application is to provide a transmission mechanism, which is applied to a cleaning device, such as Figures 1-4 described, the cleaning device includes a dust cup 1.2.3, a filter assembly 1.2.1 and a cleaning assembly 1.2.2 disposed in the dust cup 1.2.3.

[0076] The transmission mechanism includes a drive motor, a transmission assembly 2.1.2, a sensing element 2.1.9, an adsorption assembly and a controller 2.1.6. The drive motor is used to provide a driving force. By providing a stable and controllable driving force through the drive motor, the efficient operation of the cleaning assembly 1.2.2 is ensured.

[0077] The transmission assembly 2.1.2 is connected to the cleaning assembly 1.2.2 and drives the cleaning assembly 1.2.2 to move along the filter assembly 1.2.1 under the drive of the drive motor to clean the filter assembly 1.2.1 and / or the dust cup 1.2.3.

[0078] The sensing element 2.1.9 is disposed on one side of the transmission assembly 2.1.2 to determine the position of the cleaning assembly 1.2.2 by sensing the position of the transmission assembly 2.1.2. The addition of the sensing element 2.1.9 improves the positioning accuracy of the cleaning assembly 1.2.2 and ensures the efficiency of the cleaning process.

[0079] The adsorption assembly is disposed between the transmission assembly 2.1.2 and the cleaning assembly 1.2.2 and is used to connect or disconnect the transmission assembly 2.1.2 and the cleaning assembly 1.2.2. The connection between the transmission assembly 2.1.2 and the cleaning assembly 1.2.2 is flexible. Quick connection or disconnection is achieved through the adsorption assembly, which is convenient for maintenance and replacement.

[0080] The controller 2.1.6 is respectively connected to the drive motor, the adsorption assembly and the sensing element 2.1.9 to respectively control the opening and closing of the drive motor, the adsorption assembly and the sensing element 2.1.9. The integrated management of the controller 2.1.6 simplifies the operation process and improves the response speed and reliability of the system.

[0081] In this embodiment, the sensing element 2.1.9 monitors the position of the transmission assembly 2.1.2 in real time. When it is necessary to clean the filter assembly 1.2.1 and / or the inner wall of the dust cup 1.2.3, the sensing element 2.1.9 sends a sensing signal to the controller 2.1.6. After receiving the sensing signal, the controller 2.1.6 controls the adsorption assembly to connect the transmission assembly 2.1.2 with the cleaning assembly 1.2.2, and then starts the transmission motor. After the transmission motor starts, its transmission shaft rotates to drive the transmission assembly 2.1.2 to move. When the transmission assembly 2.1.2 moves, it drives the cleaning assembly 1.2.2 to move to clean the filter assembly 1.2.1 and / or the inner wall of the dust cup 1.2.3.

[0082] After the cleaning is completed, the transmission assembly 2.1.2 resets. At this time, the sensing element 2.1.9 sends the sensed sensing signal to the controller 2.1.6. After receiving the sensing signal, the controller 2.1.6 controls the adsorption assembly and the transmission motor to turn off.

[0083] In this application, the transmission assembly 2.1.2 drives the cleaning assembly 1.2.2 to clean the filter assembly 1.2.1 and / or the inner wall of the dust cup 1.2.3, and the sensing element 2.1.9 controls its reset stroke, so as to automatically complete the self-cleaning of its filtration system. It solves the problem that the transmission motor in the transmission mechanism is prone to be interfered by the outside world and cause out-of-step phenomenon when controlling the transmission assembly 2.1.2 (the transmission assembly 2.1.2 cannot reach the specified position according to the set rotation angle), enhances its stability during active cleaning, improves the product experience, and has a broad market prospect in the case of serious homogenization of product appearance and performance.

[0084] As an alternative embodiment, as Figure 1 described, the transmission assembly 2.1.2 includes a gear 2.1.2.1 and a rack 2.1.2.2.

[0085] The gear 2.1.2.1 is arranged on the transmission shaft of the transmission motor and can rotate when the transmission motor starts. The rack 2.1.2.2 meshes with the gear 2.1.2.1 and is adsorbed and connected to the cleaning assembly 1.2.2 through the adsorption assembly. When the gear 2.1.2.1 rotates and drives the rack 2.1.2.2 to move, the rack 2.1.2.2 drives the cleaning assembly 1.2.2 to move along the filter assembly 1.2.1 to clean the filter assembly 1.2.1 and / or the dust cup 1.2.3.

[0086] Through the meshing design of the gear 2.1.2.1 and the rack 2.1.2.2, the linear movement of the cleaning assembly 1.2.2 along the filter assembly 1.2.1 is realized, and the cleaning efficiency is improved. And the compact design of the transmission assembly 2.1.2 reduces the space occupation and is convenient to be integrated into the cleaning equipment.

[0087] As an alternative embodiment, as Figure 1 , Figure 3 and Figure 4 described, the cleaning assembly 1.2.2 includes a rod portion. A through hole is formed on a side of the dust cup 1.2.3 away from the filter assembly 1.2.1. One end of the rod portion can move along the through hole and extend out of the dust cup 1.2.3. The adsorption assembly includes a first magnet 1.2.2.1 and a second magnet 2.1.8.

[0088] The first magnet 1.2.2.1 is disposed on the rod portion of the cleaning assembly 1.2.2. The second magnet 2.1.8 is disposed on the rack 2.1.2.2 and can be adsorbed to the first magnet 1.2.2.1 for connecting the cleaning assembly 1.2.2 and the rack 2.1.2.2.

[0089] Wherein, the first magnet 1.2.2.1 is an iron sheet, and the second magnet 2.1.8 is an electromagnet. The iron sheet is disposed on the cleaning assembly 1.2.2, and the electromagnet is disposed on the rack 2.1.2.2. When the electromagnet is energized, it is adsorbed and connected to the iron sheet by magnetic force to realize the connection between the transmission assembly 2.1.2 and the cleaning assembly 1.2.2.

[0090] Through the adsorption design of the first magnet 1.2.2.1 and the second magnet 2.1.8, the connection method between the transmission assembly 2.1.2 and the cleaning assembly 1.2.2 is simplified, and the connection stability is improved. The use of the adsorption assembly reduces the complexity of mechanical connection and the maintenance difficulty.

[0091] As an alternative embodiment, as Figure 1 described, the rack 2.1.2.2 includes a vertical section and a horizontal section.

[0092] The vertical section has teeth and meshes with the gear 2.1.2.1 to realize the vertical movement of the rack 2.1.2.2. The horizontal section is connected to the lower end of the vertical section and extends towards the dust cup 1.2.3 and is located below the rod portion for installing the second magnet 2.1.8. Through the design of the vertical section and the horizontal section of the rack 2.1.2.2, the cleaning assembly 1.2.2 can move along the vertical section, and the horizontal section provides an installation position for the second magnet 2.1.8, simplifying the structure.

[0093] Wherein, an installation groove is formed on the horizontal section. The second magnet 2.1.8 is embedded in the installation groove and fixed in the installation groove by screws. The design of the installation groove provides a stable fixing method for the second magnet 2.1.8, improving the structural stability and durability.

[0094] As an alternative embodiment, asFigure 3 and Figure 4 As described above, the drive motor and the drive assembly 2.1.2 are both provided outside the dust cup 1.2.3, and the horizontal section of the rack 2.1.2.2 is located below the dust cup 1.2.3; the first magnet 1.2.2.1 of the adsorption assembly is located on the bottom side of the cleaning assembly 1.2.2 and is arranged in an up-and-down correspondence with the second magnet 2.1.8.

[0095] Among them, the drive motor and the drive assembly 2.1.2 are provided outside the dust cup 1.2.3, which is convenient for operation and maintenance. The first magnet 1.2.2.1 of the adsorption assembly is located on the bottom side of the cleaning assembly 1.2.2 and is arranged corresponding to the second magnet 2.1.8, which is convenient for realizing the adsorption connection between the drive assembly 2.1.2 and the cleaning assembly 1.2.2.

[0096] As an optional embodiment, as Figure 3 and Figure 4 described above, the sensing element 2.1.9 is provided outside the dust cup 1.2.3, and the setting position corresponds to the position of the upper end of the vertical section, and is used to sense the position of the rack 2.1.2.2. The outer setting of the sensing element 2.1.9 is convenient for monitoring the position of the rack 2.1.2.2 and improves the accuracy of sensing.

[0097] As an optional embodiment, when the drive assembly 2.1.2 is in the first position, it can trigger the sensing element 2.1.9 to generate a first induction signal and send it to the controller 2.1.6. The controller 2.1.6 receives the first induction signal and can control the drive motor to rotate in the first direction and control the first magnet 1.2.2.1 and the second magnet 2.1.8 to attract each other, so that the drive assembly 2.1.2 and the cleaning assembly 1.2.2 are connected.

[0098] When the drive assembly 2.1.2 moves from the first position to the second position, it triggers the sensing element 2.1.9 to generate a second induction signal and send it to the controller 2.1.6. When the drive motor rotates in the first direction to a preset angle, the controller 2.1.6 controls the drive motor to rotate in the second direction, so that the drive assembly 2.1.2 moves to the first position.

[0099] Among them, the controller receives the second induction signal to determine that the drive motor maintains the working state of rotating in the first direction, and the drive assembly and the cleaning assembly maintain the working state of connection. When the drive assembly moves to the second position, that is, when the drive motor rotates in the first direction to a preset angle, at this time the controller controls the drive motor to rotate in the second direction.

[0100] When the transmission assembly 2.1.2 moves from the second position to the first position, it triggers the sensing element 2.1.9 to generate the first sensing signal and send it to the controller 2.1.6. The controller 2.1.6 receives the first sensing signal and controls the transmission motor to turn off and controls the disconnection of the first magnet 1.2.2.1 and the second magnet 2.1.8, so that the transmission assembly 2.1.2 and the cleaning assembly 1.2.2 are disconnected.

[0101] Wherein, when the transmission assembly 2.1.2 is in the first position, the cleaning assembly 1.2.2 is located at the upper end of the filtering assembly 1.2.1, and when the transmission assembly 2.1.2 is in the second position, the cleaning assembly 1.2.2 is located at the lower end of the filtering assembly 1.2.1.

[0102] In this embodiment, when the transmission assembly 2.1.2 moves to a specific position, it triggers the sensing element 2.1.9 to generate a sensing signal. The controller 2.1.6 receives the sensing signal and controls the rotation direction of the transmission motor and the opening and closing of the adsorption assembly.

[0103] Exemplarily, the transmission assembly 2.1.2 is a rack 2.1.2.2 and a gear 2.1.2.1, the adsorption assembly is an iron sheet and an electromagnet, and the controller 2.1.6 is a PCB circuit board. The working process of the transmission mechanism is as follows:

[0104] After the cleaning device completes the dust suction work and completes the first dust collection of the garbage in the dust cup 1.2.3, when the transmission assembly 2.1.2 is in the initial position (the first position), the sensing element 2.1.9 sends the first sensing signal X to the PCB circuit board. At this time, the PCB circuit board controls the electromagnet to be energized, so that the electromagnet adsorbs to the iron sheet, and further connects the rack 2.1.2.2 and the cleaning assembly 1.2.2 together.

[0105] When the transmission assembly 2.1.2 drives the cleaning assembly 1.2.2 to move along the filtering assembly 1.2.1, the transmission motor rotates counterclockwise (the first direction), so that the gear 2.1.2.1 rotates to drive the rack 2.1.2.2 to move downward. At this time, the sensing element 2.1.9 sends the second sensing signal Y to the PCB circuit board to enable the PCB circuit board to confirm that the transmission mechanism is working properly.

[0106] During the process of cleaning the inner wall of the filter component 1.2.1 and / or the dust cup 1.2.3, the position of the transmission component 2.1.2 is controlled by setting the rotation angle of the drive motor. After the transmission component 2.1.2 drives the cleaning component 1.2.2 to move to the specified position (the second position), the PCB circuit board controls the drive motor to start rotating clockwise (the second direction), so that the gear 2.1.2.1 rotates in the reverse direction to drive the rack 2.1.2.2 to move upward. At this time, the end point of the position (the first position) is controlled by the sensing element 2.1.9.

[0107] When the gear 2.1.2.1 drives the rack 2.1.2.2 to move upward all the way and return to the initial position (the first position), the sensing signal sent by the sensing element 2.1.9 to the PCB board is converted from the second sensing signal Y to the first sensing signal X. At this time, the cleaning component 1.2.2 is reset to the initial state, and a self-cleaning of the filtration system is completed.

[0108] In this application, a sensing element 2.1.9 is added at the initial position of the movement of the transmission component 2.1.2, so that the transmission component 2.1.2 does not need to control the final point of the movement of the transmission component 2.1.2 by the rotation angle set by the drive motor during the reset movement. Instead, when the transmission component 2.1.2 moves to the initial position, the start and stop and rotation of the drive motor are controlled by the signal sensed by the sensing element 2.1.9, reducing the interference suffered by the drive motor in the process of controlling the transmission component 2.1.2, and improving the stability of the transmission movement and the perfection of the function.

[0109] The purpose of the embodiment of this application is to further provide a cleaning device, such as Figures 5-9 described, including a vacuum cleaner component 1, the vacuum cleaner component 1 includes a handle component 1.1, a dust cup component 1.2 and a floor brush component 1.4. The dust cup component 1.2 includes a dust cup 1.2.3, a filter component 1.2.1 provided in the dust cup 1.2.3 and a cleaning component 1.2.2, and also includes the transmission mechanism as described above.

[0110] Specifically, the handle component 1.1 is responsible for supplying power and suction to the vacuum cleaner component 1, and serving as an input to control the start and stop of the vacuum cleaner component 1. The folding tube component 1.3 connects the floor brush component 1.4 and the handle component, providing a recovery channel and a working current transmission path for the vacuum cleaner component 1. The floor brush component 1.4 is responsible for cleaning the floor, and bringing garbage and dirt back into the dust cup component 1.2 through the recovery channel.

[0111] The filtering component 1.2.1 filters out tiny particles and dirt inhaled during the operation of the vacuum cleaner. The cleaning component 1.2.2 is responsible for cleaning the dirt remaining on the inner wall of the filtering component 1.2.1 and / or the dust cup 1.2.3. The dust cup 1.2.3 is responsible for collecting the garbage cleaned during the operation of the vacuum cleaner. A first magnet 1.2.2.1 is provided on the cleaning component 1.2.2 for connecting with the second magnet 2.1.8 so that the transmission mechanism drives the cleaning component 1.2.2 to move.

[0112] The working process of the cleaning device is as follows:

[0113] First, when cleaning, power is supplied to the vacuum cleaner component 1 through the handle component, and at the same time, the suction motor and the roller brush drive motor of the vacuum cleaner are started to operate. The floor brush component 1.4 sweeps the dust and garbage on the ground to the recovery port of the folding tube component 1.3, and the suction motor of the vacuum cleaner transmits the dust and garbage through the recovery channel of the folding tube component 1.3 to the dust cup component 1.2 by suction, after completing the cleaning of the ground.

[0114] As an optional embodiment, as Figures 5-9 described, the cleaning device further includes a dust collection station component 2 for collecting the garbage in the dust cup 1.2.3. The dust collection station component 2 includes a dust collection station head component 2.1. The dust collection station head component 2.1 includes an installation cavity 2.1.1.1 and an installation position 2.1.1.2. The installation cavity 2.1.1.1 is used to accommodate the dust cup 1.2.3, and the installation position 2.1.1.2 is used to install the transmission mechanism. The bottom of the installation position 2.1.1.2 communicates with the installation cavity 2.1.1.1. When the dust cup 1.2.3 is placed in the installation cavity 2.1.1.1, the rod part of the cleaning component 1.2.2 passes through the through-hole of the dust cup 1.2.3 and is connected to the transmission mechanism to drive the cleaning component 1.2.2 to move under the drive of the transmission mechanism.

[0115] In this embodiment, the dust collection station component 2 further includes a ventilation pipe component 2.2, a base station base component 2.4, and a dust collection box component 2.3. The ventilation pipe component 2.2 is responsible for connecting the dust collection station head component 2.1 and the base station base component 2.4 and providing a dust collection channel. The base station base component 2.4 generates suction through a suction motor, and then collects the garbage in its dust cup component 1.2 into the dust collection box component 2.3 together through the ventilation pipe component 2.2. The dust collection box component 2.3 is responsible for collecting the garbage and dirt collected in the dust cup 1.2.3 during automatic dust collection.

[0116] The dust collection station head assembly 2.1 includes a head upper cover 2.1.1, a charging sheet assembly 2.1.3, an air duct interface 2.1.4, a micro switch, and a head main body 2.1.7. The charging sheet assembly 2.1.3 provides a charging function for the vacuum cleaner. The air duct interface 2.1.4 connects the head upper cover 2.1.1 and the ventilation pipe assembly 2.2 to form a dust collection channel. The micro switch is responsible for detecting whether the vacuum cleaner assembly 1 is placed in the dust collection station assembly 2. Both the charging sheet assembly 2.1.3 and the micro switch are connected to the controller 2.1.6.

[0117] Among them, the head main body 2.1.7 is detachably connected to the head upper cover 2.1.1. The center of the upper part of the head upper cover 2.1.1 is open and extends downward to form an installation cavity 2.1.1.1 for placing the dust cup 1.2.3. A partial outer peripheral edge of the upper part of the head upper cover 2.1.1 extends upward to form an installation position 2.1.1.2 for installing the transmission mechanism.

[0118] The working process of the cleaning device is as follows:

[0119] After the vacuum cleaner assembly 1 finishes working and is put back into the dust collection station assembly 2, the dust collection station assembly 2 sucks the garbage in its vacuum cleaner assembly 1 into the dust collection box together for automatic dust collection. During the second dust collection, the cleaning component 1.2.2 in the dust cup 1.2.3 automatically cleans the filter component 1.2.1 and / or the inner wall of the dust cup 1.2.3.

[0120] Specifically, when the dust cup 1.2.3 is placed in the installation cavity, the micro switch is triggered. After the micro switch closes, it outputs a signal to the controller 2.1.6, and the dust collection station assembly 2 performs the first dust collection.

[0121] After the first dust collection is completed, after a few seconds of delay set by the program, it enters the dust collection state again. At this time, the controller 2.1.6 controls the electromagnet and the drive motor to enter the working state according to the induction signal of the induction element 2.1.9 to start self-cleaning.

[0122] Among them, when the vacuum cleaner is placed in the dust collection station and the first dust collection is completed, when entering the dust collection again, the controller 2.1.6 receives the first induction signal X, controls the electromagnet to be energized and attract the iron sheet, so that the transmission component 2.1.2 is connected to the cleaning component 1.2.2.

[0123] The controller 2.1.6 controls the drive motor to start reversing, so as to drive the gear 2.1.2.1 to rotate. The gear 2.1.2.1 meshes with the rack 2.1.2.2, driving the rack 2.1.2.2 to move downward. At the same time, the sensing element 2.1.9 sends a second sensing signal Y (the first sensing signal X is converted into the second sensing signal Y) to enable the controller 2.1.6 to confirm that the transmission mechanism maintains a normal working state. And at this time, the cleaning assembly 1.2.2 also moves downward through the coupling action between the iron sheet and the electromagnet to clean the inner wall of the filter assembly 1.2.1 and / or the dust cup 1.2.3.

[0124] When the drive motor drives the gear 2.1.2.1 to rotate to a set angle, at this time, the cleaning assembly 1.2.2 is at the lower end of the filter assembly 1.2.1. The controller 2.1.6 controls the drive motor to start rotating forward. The gear 2.1.2.1 drives the rack 2.1.2.2 to move upward, and at the same time, the cleaning assembly 1.2.2 moves upward to clean the inner wall of the filter assembly 1.2.1 and / or the dust cup 1.2.3.

[0125] When the rack 2.1.2.2 moves upward and returns to the initial state, the sensing element 2.1.9 sends a first sensing signal X (the second sensing signal Y is converted into the first sensing signal X) to the controller 2.1.6. The controller 2.1.6 controls the drive motor to stop rotating forward, and controls the electromagnet to cut off the power to lose the coupling effect with the iron sheet. The cleaning assembly 1.2.2 returns to the upper end of the filter assembly 1.2.1, and the self-cleaning work is completed once.

Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
