Description

Technical Field

[0001] The present invention belongs to the technical field of filter screen cleaning, and particularly relates to a vacuum cleaner with a filter screen that is convenient for cleaning and dust scraping. Background Art

[0002] A vacuum cleaner is a cleaning appliance that uses an electric motor to drive the blades to rotate at high speed, generating a negative air pressure inside a sealed housing, thereby sucking dust debris into the dust collection device and discharging the filtered air at a very high speed from the blower. Vacuum cleaners are classified by their functions into dry vacuum cleaners and wet-dry vacuum cleaners. Dry vacuum cleaners generally include dust bag type and dust cup type.

[0003] An industrial vacuum cleaner is a cleaning device specifically used in the industrial field. Industrial vacuum cleaners are usually equipped with high-power motors that can generate strong suction. This suction can easily suck up a large amount of heavy pollutants such as dust, debris, and metal particles in various industrial sites. For example, in a machining workshop, an industrial vacuum cleaner can quickly clean up the metal chips and oil stains generated during the cutting process, keeping the workshop environment clean. The dust collection bucket of an industrial vacuum cleaner has a large capacity and can hold a large amount of dust and waste. This reduces the frequency of cleaning the dust collection bucket during the cleaning process and improves work efficiency. For example, in a large warehouse or factory workshop, a large-capacity dust collection bucket can work for a long time without frequent interruption for cleaning, saving time and labor costs.

[0004] Publication No. CN115518468A discloses a filter for a vacuum cleaner with a filter screen that is convenient for cleaning and dust scraping, including: a filter housing and a dust scraper. At least one filter screen is provided on the side wall of the filter housing. The dust scraper includes an annular frame body and a soft rubber ring. The annular frame body is sleeved on the filter housing, and the soft rubber ring is fixedly installed on the lower edge of the annular frame body. The soft rubber ring is in interference fit with the filter screen, and the inner side wall of the soft rubber ring contacts the surface of the filter screen. Compared with the prior art, this invention can effectively remove the hair and fine sticky dust on the filter screen in the filter, with convenient cleaning and high cleaning efficiency.

[0005] During the operation of the vacuum cleaner, the filter screen will intercept impurities such as dust, hair, and debris. If the filter screen is not cleaned for a long time, these impurities will gradually accumulate, clogging the pores of the filter screen and causing the air circulation to be blocked. Cleaning the filter screen can remove these blockages, allowing air to pass through the filter screen smoothly, thereby maintaining the strong suction of the vacuum cleaner. For example, when the filter screen is clogged, the vacuum cleaner may not be able to effectively pick up the dust on the ground. After cleaning, the suction is restored, and it can easily clean various dirt. If the filter screen is not cleaned, the suction of the vacuum cleaner will weaken, and it may be necessary to vacuum back and forth several times to achieve the cleaning effect. Therefore, this device provides a vacuum cleaner with a filter screen that is convenient for cleaning and dust scraping. Summary of the Invention

[0006] An embodiment of the present invention provides a vacuum cleaner with a filter screen that is convenient for cleaning and ash scraping to solve the problems in the prior art.

[0007] The embodiment of the present invention adopts the following technical solutions: It includes a vacuum cleaner, and also includes a cleaning device for scraping and cleaning the surface of the internal filter screen of the vacuum cleaner, a driving device for the cleaning device to run in a circular motion, an adjusting device for adjusting the cleaning intensity of the cleaning device, a flipping device for flipping the cleaning device, and an optimized cleaning device for the flipping device to reciprocally float along a regular route. The vacuum cleaner is placed on a horizontal plane. The driving device is located outside the vacuum cleaner. The adjusting device is arranged on the driving device and is located inside the vacuum cleaner. The cleaning device is arranged on the adjusting device and is located beside the internal filter screen of the vacuum cleaner. The optimized cleaning device is arranged on the inner side wall of the vacuum cleaner.

[0008] Further, the driving device includes a driving motor, a housing, a driving wheel, a driven wheel, and a belt. The driving motor is arranged outside the vacuum cleaner. The housing is arranged outside the vacuum cleaner and the inside of the housing is in communication with the inside of the vacuum cleaner. The driving wheel is rotatably arranged inside the housing. The output end of the driving motor penetrates into the inside of the housing from the outside of the upper end of the housing and is connected to the driving wheel. The driven wheel is rotatably arranged on the inner side wall of the inside of the vacuum cleaner. The driving wheel and the driven wheel are sleeved with a belt.

[0009] Further, the adjusting device includes an adjusting frame, a mini electric cylinder, and an adjusting block. The adjusting frame is arranged on the inner side wall of the driven wheel. The mini electric cylinder is also arranged on the inner side wall of the driven wheel and the output end of the mini electric cylinder passes through the adjusting frame for telescopic sliding fit. The adjusting block is arranged on the output end of the mini electric cylinder.

[0010] Further, the cleaning device includes a telescopic rod, a cleaning rod, and a cleaning brush. The telescopic rod is telescopically arranged. The lower end of the telescopic rod is arranged on the adjusting block. The cleaning rod penetrates through the upper end of the telescopic rod and is rotatably connected. The cleaning brush is arranged at one end of the cleaning rod facing the internal filter screen of the vacuum cleaner.

[0011] Further, the cleaning brush is inclined and the inclination angle is consistent with the inclination angle of the internal filter screen of the vacuum cleaner.

[0012] Further, the cleaning brush is detachably arranged on the cleaning rod.

[0013] Further, the flipping device includes a flipping frame and a micro motor. The flipping frame is arranged at the upper end of the telescopic rod. The micro motor is arranged on the flipping frame and the output end of the micro motor is connected to the cleaning rod.

[0014] Further, the optimized cleaning device includes an auxiliary ring, a connecting rod, and a ball. The auxiliary ring is arranged on the inner side wall of the vacuum cleaner and above the driven wheel. The head end of the connecting rod is connected to the end of the flipping frame, and the ball is arranged at the end of the connecting rod. A plurality of V-shaped grooves are evenly arranged around the auxiliary ring in a circular manner, and the plurality of V-shaped grooves are sequentially connected end to end and communicated. The ball is located in the corresponding V-shaped groove and is slidably matched with the V-shaped groove in a suitable size.

[0015] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0016] First, when there is a lot of dust on the filter net and it needs to be cleaned, or when the vacuum cleaner inhales a large amount of dust during the dust suction operation, the micro motor is started to drive the cleaning rod on the output end of the micro motor to rotate. The rotation of the cleaning rod drives the cleaning brush to rotate and makes the cleaning brush rotate to a horizontal state. At this time, the micro motor stops running. Then, the mini electric cylinder is started to drive the adjusting block on the output end of the mini electric cylinder to move towards the filter net. The movement of the adjusting block towards the filter net drives the cleaning device to move towards the filter net. Finally, the cleaning brush is relatively close to the surface of the filter net. At this time, the mini electric cylinder stops running. Then, the driving motor runs to drive the driving wheel on the output end of the driving motor to rotate. The rotation of the driving wheel drives the driven wheel to rotate on the inner wall of the vacuum cleaner through the sleeving of the belt. The rotation of the driven wheel drives the adjusting device to rotate around the filter net. The rotation of the adjusting device around the filter net will ultimately drive the cleaning device to rotate around the filter net. Since the cleaning brush is close to the surface of the filter net, the dust on the surface of the filter net will be brushed off by the way of circular rotation, and the cleaning brush being close to the surface of the filter net can maximize the brushing force of the cleaning brush. Thus, for the cleaning of a large amount of dust on the filter net or the dust scraping operation when the vacuum cleaner inhales a large amount of dust during the dust suction operation, the cleaning brush brushes off the dust on the surface of the filter net in a circular rotation mode, and the whole process is in a horizontal movement state. On this premise, the ball is located inside the corresponding V-shaped groove. Therefore, during the circular movement state of the cleaning brush, the ball also runs synchronously and is located inside the corresponding V-shaped groove and runs synchronously. Through the fact that several of the said V-shaped grooves are connected in sequence end to end and the ball is located inside the corresponding V-shaped groove and is in sliding fit with the V-shaped groove with a matching size, and the telescopic rod is telescopically arranged, the ball not only makes a circular rotation movement through the connection of the connecting rod, but also makes a corresponding movement according to the internal track of the corresponding V-shaped groove, that is, an up and down reciprocating movement operation. Thus, on the premise of driving the cleaning brush to rotate in a circular motion to brush off the dust on the surface of the filter net, the cleaning brush is also in an up and down reciprocating movement state. Furthermore, the dust and impurities that are difficult to scrape off horizontally on the filter net are scraped off by the cleaning brush almost all-roundly on the surface of the filter net, which plays a role in preventing the filter net from being blocked, affecting the suction effect of the vacuum cleaner and weakening the suction force, and reducing the load of the vacuum cleaner and reducing wear, always keeping the surface of the filter net in a state with less dust, thereby improving the service life and always keeping the suction in a strong state and the suction effect, and also reducing the repeated labor of the vacuum cleaner and reducing the load.

[0017] Second, when there is less dust on the filter net and cleaning is required, or when the vacuum cleaner is not in the suction operation state, the micro motor is started to drive the cleaning rod on the output end of the micro motor to rotate. The rotation of the cleaning rod drives the cleaning brush to rotate, and the cleaning brush rotates to a vertical state. At this time, the micro motor stops running. Then, the mini electric cylinder is started to drive the adjustment block on the output end of the mini electric cylinder to move towards the filter net. The movement of the adjustment block towards the filter net drives the cleaning device to move towards the filter net. Finally, after the cleaning brush is in contact with the surface of the filter net, the mini electric cylinder stops running. At this time, the driving motor runs to drive the cleaning device to move, so that the cleaning brush brushes off the dust on the surface of the filter net in a way of circumferential rotation and up-and-down reciprocating movement, realizing the scraping of the dust on the surface of the filter net. Since there is less dust on the filter net, in order to avoid excessive and large friction between the cleaning brush and the filter net, this method can not only clean the dust on the surface of the filter net, but also reduce the wear between components, thereby improving the service life and suction effect of the vacuum cleaner.

[0018] Third, when dealing with dust and impurities that are difficult to remove on the surface of the filter net, or when the vacuum cleaner inhales plastic hard objects during the suction operation. Since most plastic hard objects will collide with the filter net after being inhaled by the vacuum cleaner, which may cause wear to the filter net, and some small plastic hard objects may get stuck on the filter net after colliding with the filter net. At this time, the device starts the mini electric cylinder to drive the adjustment block on the output end of the mini electric cylinder to move towards the filter net. The movement of the adjustment block towards the filter net drives the cleaning device to move towards the filter net. Finally, after the cleaning brush is in contact with the surface of the filter net, the driving motor runs to drive the cleaning device to move, so that the cleaning brush brushes off the dust on the surface of the filter net in a way of circumferential rotation and up-and-down reciprocating movement. On this premise, the micro motor is started to drive the cleaning rod on the output end of the micro motor to rotate. The rotation of the cleaning rod drives the cleaning brush to rotate. In this way, on the premise that the cleaning brush rotates around the vacuum cleaner and moves up and down reciprocally, it will also perform a self-rotation dust scraping operation, thereby brushing off the dust and impurities that are difficult to remove on the surface of the filter net, and being able to scrape off the plastic hard objects stuck on the filter net. At the same time, through this movement method, it is possible to reduce the probability of collision with the filter net after the vacuum cleaner inhales plastic hard objects, thereby reducing the wear of the filter net.

Detailed description of the specific embodiments

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the specific embodiments and corresponding drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] The following will describe in detail the technical solutions provided by each embodiment of the present invention with reference to the drawings.

[0032] An embodiment of the present invention provides a vacuum cleaner with a filter screen that is convenient for cleaning and dust scraping, including a vacuum cleaner 1, and further including a cleaning device 4 for scraping and cleaning the surface of the internal filter screen 11 of the vacuum cleaner 1, a driving device 2 for the cleaning device 4 to run around, an adjusting device 3 for adjusting the cleaning strength of the cleaning device 4, a flipping device 5 for flipping the cleaning device 4, and an optimized cleaning device 6 for reciprocatingly floating the flipping device 5 along a regular route. The vacuum cleaner 1 is placed on a horizontal plane. The driving device 2 is located outside the vacuum cleaner 1. The adjusting device 3 is arranged on the driving device 2 and is located inside the vacuum cleaner 1. The cleaning device 4 is arranged on the adjusting device 3 and is located beside the internal filter screen 11 of the vacuum cleaner 1. The optimized cleaning device 6 is arranged on the inner side wall of the vacuum cleaner 1;

[0033] This device can perform surface cleaning and dust scraping operations on the internal filter screen 11 of a traditional industrial vacuum cleaner 1. Integrated with the vacuum cleaner 1, it can synchronously perform dust scraping operations on the surface of the filter screen 11 during the vacuuming operation. And through diversified dust scraping operations, it can prevent the filter screen 11 from being blocked, affecting the suction effect of the vacuum cleaner 1 and weakening the suction force, as well as reducing the load of the vacuum cleaner 1 and reducing wear, thereby improving the service life and keeping the suction of the vacuum cleaner 1 always in a strong state and the suction effect.

[0034] This device can scrape the operation through a variety of different methods to adapt to the corresponding scraping method during the vacuuming operation of the vacuum cleaner 1, and optimize the vacuuming effect and cleaning effect.

[0035] This device is used for scraping operations on the filter screen 11 in a high-power vacuum cleaner 1 such as an industrial vacuum cleaner 1. And if other types of vacuum cleaners 1 have the same structural principle as the industrial vacuum cleaner 1, the same method of scraping dust on the filter screen 11 can also be adopted.

[0036] Preferably, the driving device 2 includes a driving motor 21, a housing 22, a driving wheel 23, a driven wheel 24, and a belt 25. The driving motor 21 is arranged outside the vacuum cleaner 1. The housing 22 is arranged outside the vacuum cleaner 1 and the inside of the housing 22 is in communication with the inside of the vacuum cleaner 1. The driving wheel 23 is rotatably arranged inside the housing 22. The output end of the driving motor 21 penetrates into the inside of the housing 22 from the outside of the upper end of the housing 22 and is connected to the driving wheel 23. The driven wheel 24 is rotatably arranged on the inner side wall of the vacuum cleaner 1. The driving wheel 23 and the driven wheel 24 are sleeved with the belt 25. The adjusting device 3 includes an adjusting frame 31, a mini electric cylinder 32, and an adjusting block 33. The adjusting frame 31 is arranged on the inner side wall of the driven wheel 24. The mini electric cylinder 32 is also arranged on the inner side wall of the driven wheel 24 and the output end of the mini electric cylinder 32 passes through the adjusting frame 31 for telescopic sliding fit. The adjusting block 33 is arranged on the output end of the mini electric cylinder 32;

[0037] The telescopic length of the cleaning brush 43 can be adjusted by the adjusting device 3, so as to adjust the contact between the cleaning brush 43 and the surface of the filter net 11, thereby enabling the cleaning brush 43 to achieve different cleaning and scraping effects for different contact states.

[0038] Preferably, the cleaning treatment device 4 includes a telescopic rod 41, a cleaning rod 42 and a cleaning brush 43. The telescopic rod 41 is telescopically arranged. The lower end of the telescopic rod 41 is arranged on the adjusting block 33. The cleaning rod 42 passes through the upper end of the telescopic rod 41 and is rotatably connected. The cleaning brush 43 is arranged at one end of the cleaning rod 42 facing the filter net 11 inside the vacuum cleaner 1. The cleaning brush 43 is inclined, and the inclination angle is consistent with the inclination angle of the filter net 11 inside the vacuum cleaner 1. The cleaning brush 43 is detachably arranged on the cleaning rod 42;

[0039] Since the cleaning brush 43 is detachably arranged, when the device does not need to perform vacuuming operation, the cleaning brush 43 can be removed for cleaning or replacement, which improves the practicability.

[0040] Preferably, the flipping device 5 includes a flipping frame 51 and a micro motor 52. The flipping frame 51 is arranged at the upper end of the telescopic rod 41. The micro motor 52 is arranged on the flipping frame 51, and the output end of the micro motor 52 is connected to the cleaning rod 42;

[0041] The flipping device 5 can drive the cleaning brush 43 to rotate, so as to change the placement state of the cleaning brush 43. The cleaning brush 43 can be in a vertical state, a horizontal state, an inclined state, etc., preferably in a 360-degree state. Moreover, the flipping device 5 can also drive the cleaning brush 43 to continuously rotate itself, thereby enabling the cleaning brush 43 to achieve different cleaning and scraping effects for different placement states.

[0042] Preferably, the optimized cleaning device 6 includes an auxiliary ring 61, a connecting rod 62 and a ball 63. The auxiliary ring 61 is arranged on the inner side wall inside the vacuum cleaner 1 and above the driven wheel 24. The head end of the connecting rod 62 is connected to the end of the flipping frame 51. The ball 63 is arranged at the end of the connecting rod 62. A number of V-shaped grooves 611 are evenly arranged around the auxiliary ring 61, and a number of the V-shaped grooves 611 are connected in sequence end to end. The ball 63 is located in the corresponding V-shaped groove 611 and is slidably matched with the V-shaped groove 611 in a suitable size;

[0043] When a large amount of dust accumulates on the filter net 11 and needs to be cleaned, or when the vacuum cleaner 1 sucks in a large amount of dust during the vacuuming operation, the micro motor 52 is started to drive the cleaning rod 42 on the output end of the micro motor 52 to rotate. The rotation of the cleaning rod 42 drives the cleaning brush 43 to rotate, and the cleaning brush 43 rotates to a horizontal state. At this time, the micro motor 52 stops running. Then, the mini electric cylinder 32 is started to drive the adjusting block 33 on the output end of the mini electric cylinder 32 to move towards the filter net 11. The movement of the adjusting block 33 towards the filter net 11 drives the cleaning device 4 to move towards the filter net 11. Finally, the cleaning brush 43 is closely attached to the surface of the filter net 11. At this time, the mini electric cylinder 32 stops running. Refer to Figure 5 As shown, at this time, the driving motor 21 runs to drive the driving wheel 23 on the output end of the driving motor 21 to rotate. The rotation of the driving wheel 23 drives the driven wheel 24 to rotate on the inner side wall of the vacuum cleaner 1 through the sleeving of the belt 25. The rotation of the driven wheel 24 drives the adjusting device 3 to rotate around the filter net 11, and the rotation of the adjusting device 3 around the filter net 11 will ultimately drive the cleaning device 4 to rotate around the filter net 11. Since the cleaning brush 43 is closely attached to the surface of the filter net 11, the dust on the surface of the filter net 11 will be brushed off in a circular motion, and the cleaning brush 43 being closely attached to the surface of the filter net 11 can maximize the brushing force of the cleaning brush 43. Thus, for the cleaning of a large amount of dust on the filter net 11 or the dust scraping operation when the vacuum cleaner 1 sucks in a large amount of dust during the vacuuming operation, the entire process of the cleaning brush 43 brushing off the dust on the surface of the filter net 11 in a circular motion is in a horizontal movement state. On this premise, the ball 63 is located inside the corresponding V-shaped groove 611. Therefore, during the circular motion state of the cleaning brush 43, the ball 63 also runs synchronously and is located inside the corresponding V-shaped groove 611. And through the fact that several of the V-shaped grooves 611 are connected in sequence end to end and the ball 63 is located inside the corresponding V-shaped groove 611 and is in sliding fit with the V-shaped groove 611 in a matching size, and the telescopic rod 41 is telescopically arranged, the ball 63 not only rotates in a circular motion through the connection of the connecting rod 62, but also makes corresponding movements according to the internal trajectory of the corresponding V-shaped groove 611, that is, up and down reciprocating movements. Thus, on the premise of driving the cleaning brush 43 to rotate in a circular motion to brush off the dust on the surface of the filter net 11, the cleaning brush 43 is also in an up and down reciprocating movement state. Furthermore, the dust and impurities on the filter net 11 that are difficult to scrape off horizontally are scraped off almost all over the surface of the filter net 11 by the cleaning brush 43, which plays a role in preventing the filter net 11 from being blocked, affecting the suction effect of the vacuum cleaner 1 and weakening the suction, as well as reducing the load of the vacuum cleaner 1 and reducing wear, always keeping the surface of the filter net 11 in a state with less dust, thereby improving the service life and always maintaining a strong suction state for the vacuum cleaner 1, and also reducing the repeated labor of the vacuum cleaner 1 and reducing the load.

[0044] When there is less dust on the filter net 11 and cleaning is required, or when the vacuum cleaner 1 is not in the vacuuming operation, the micro motor 52 is started to drive the cleaning rod 42 on the output end of the micro motor 52 to rotate. The rotation of the cleaning rod 42 drives the cleaning brush 43 to rotate, and the cleaning brush 43 rotates to a vertical state. At this time, the micro motor 52 stops running. Then, the mini electric cylinder 32 is started to drive the adjustment block 33 on the output end of the mini electric cylinder 32 to move towards the filter net 11. The movement of the adjustment block 33 towards the filter net 11 drives the cleaning device 4 to move towards the filter net 11. Finally, after the cleaning brush 43 is in contact with the surface of the filter net 11, the mini electric cylinder 32 stops running. Refer to Figure 4 As shown, at this time, the driving motor 21 runs to drive the cleaning device 4 to move, so that the cleaning brush 43 brushes off the dust on the surface of the filter net 11 in a way of circumferential rotation and up-and-down reciprocating movement, realizing the scraping of the dust on the surface of the filter net 11. Since there is less dust on the filter net 11, in order to avoid excessive and large friction between the cleaning brush 43 and the filter net 11, this method can not only clean the dust on the surface of the filter net 11, but also reduce the wear between components, thereby improving the service life and vacuuming effect of the vacuum cleaner 1;

[0045] When there are dust impurities on the surface of the filter net 11 that are difficult to remove, or when the vacuum cleaner 1 inhales plastic hard objects during the vacuuming operation, since most of the plastic hard objects will collide with the filter net 11 after being inhaled by the vacuum cleaner 1, which will cause wear of the filter net 11, and some smaller plastic hard objects may get stuck on the filter net 11 after colliding with the filter net 11. At this time, the device starts the mini electric cylinder 32 to drive the adjustment block 33 on the output end of the mini electric cylinder 32 to move towards the filter net 11. The movement of the adjustment block 33 towards the filter net 11 drives the cleaning device 4 to move towards the filter net 11. Finally, after the cleaning brush 43 is in contact with the surface of the filter net 11, the driving motor 21 runs to drive the cleaning device 4 to move, so that the cleaning brush 43 brushes off the dust on the surface of the filter net 11 in a way of circumferential rotation and up-and-down reciprocating movement. On this premise, the micro motor 52 is started to drive the cleaning rod 42 on the output end of the micro motor 52 to rotate. The rotation of the cleaning rod 42 drives the cleaning brush 43 to rotate. In this way, on the premise that the cleaning brush 43 rotates around the vacuum cleaner 1 and moves up and down reciprocally, it will also perform a self-rotation dust scraping operation, thereby brushing off the dust impurities on the surface of the filter net 11 that are difficult to remove, and being able to scrape off the plastic hard objects stuck on the filter net 11. At the same time, through this movement method, it is possible to block the probability of collision with the filter net 11 after the vacuum cleaner 1 inhales plastic hard objects, thereby reducing the wear of the filter net 11.

[0046] Cleaning the internal filter net 11 of the vacuum cleaner 1 has the following effects:

[0047] I. Influence on the dust suction effect

[0048] Maintain strong suction

[0049] Prevent blockage: During the operation of the vacuum cleaner 1, the filter net 11 will intercept impurities such as dust, hair, and debris. If the filter net 11 is not cleaned for a long time, these impurities will gradually accumulate, block the pores of the filter net 11, and cause the air circulation to be blocked. Cleaning the filter net 11 can remove these blockages, enable the air to pass through the filter net 11 smoothly, and thus maintain the strong suction of the vacuum cleaner 1. For example, when the filter net 11 is blocked, the vacuum cleaner 1 may not be able to effectively suck up the dust on the ground. After cleaning, the suction power is restored, and various dirt can be easily cleaned up.

[0050] Optimize the air flow: A clean filter net 11 can ensure the normal flow of air inside the vacuum cleaner 1. Good air flow can improve the dust suction efficiency, enabling the vacuum cleaner 1 to suck dust and debris into the dust collection bucket more quickly. Cleaning the filter net 11 helps to maintain the air flow balance inside the vacuum cleaner 1 and improve the dust suction effect.

[0051] Improve the cleaning efficiency

[0052] Reduce repetitive labor: If the filter net 11 is not cleaned, the suction power of the vacuum cleaner 1 will weaken, and it may be necessary to suck the dust back and forth several times to achieve the cleaning effect. After cleaning the filter net 11, the working efficiency of the vacuum cleaner 1 is improved, and the cleaning task can be completed in a shorter time, reducing the labor intensity and time cost of the user. For example, when cleaning a large area room, the cleaned vacuum cleaner 1 can complete the cleaning in one go, instead of repeatedly cleaning the same area many times.

[0053] II. Influence on the equipment performance and service life

[0054] Protect the motor

[0055] Reduce the load: A clean filter net 11 can reduce the dust and impurities entering the motor, reducing the working load of the motor. If the filter net 11 is blocked, the motor needs more power to overcome the resistance, which will cause the motor to overheat and shorten the service life of the motor. Cleaning the filter net 11 can protect the motor and extend the service life of the vacuum cleaner 1.

[0056] Reduce wear: After dust and impurities enter the motor, they will cause wear on the internal components of the motor. Cleaning the filter net 11 can prevent these impurities from entering the motor, reduce the wear of the motor, and improve the reliability and stability of the motor.

[0057] Maintain the stable performance of the equipment

[0058] Ensure normal operation: The filter net 11 is an important component of the vacuum cleaner 1, and its cleanliness directly affects the overall performance of the vacuum cleaner 1. If the filter net 11 is not clean, various faults may occur in the vacuum cleaner 1, such as reduced suction, increased noise, abnormal heating, etc. Regularly cleaning the filter net 11 can ensure that the vacuum cleaner 1 always maintains a good performance state and operates stably.

[0059] Extend service life: By cleaning the filter net 11, the damage to other components of the vacuum cleaner 1 can be reduced, and the overall service life of the vacuum cleaner 1 can be extended. This not only saves the cost of replacing equipment but also reduces the generation of electronic waste, which is more environmentally friendly.

[0060] III. Impact on indoor air quality

[0061] Filter air
