Description

Technical Field

[0001] The invention belongs to the technical field of filter screen cleaning, and in particular relates to a vacuum cleaner with a filter screen that is easy to clean and scrape dust. Background Art A vacuum cleaner is a cleaning appliance that uses a motor to drive the blades to rotate at high speed, creating negative air pressure in a sealed shell, thereby sucking dust into the dust collection device and expelling the filtered air out of the fan at an extremely high speed. Vacuum cleaners are classified according to their functions into dry vacuum cleaners and wet and dry vacuum cleaners. Dry vacuum cleaners generally include dust bag type and dust cup type.

[0002] Industrial vacuum cleaners are cleaning equipment specially used in the industrial field. Industrial vacuum cleaners are usually equipped with high-power motors that can generate strong suction. This suction can easily remove a large amount of dust, debris, metal particles and other heavy pollutants 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 to keep the workshop environment clean. The dust collection bucket of an industrial vacuum cleaner has a large capacity and can accommodate a large amount of dust and waste. This reduces the number of times the dust collection bucket needs to be cleaned frequently 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 interruptions for cleaning, saving time and labor costs.

[0003] Publication No. CN115518468A discloses a vacuum cleaner filter with a filter screen that is easy to clean and scrape dust, comprising: a filter housing and a dust scraper, at least one filter screen is arranged on the side wall of the filter housing, the dust scraper comprises an annular frame and a soft rubber ring, the annular frame is sleeved on the filter housing, the soft rubber ring is fixedly installed on the lower edge of the annular frame, the soft rubber ring is interference fitted 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, the invention effectively removes hair and fine sticky dust on the filter screen in the filter, is easy to clean and has high cleaning efficiency.

[0004] During the operation of the vacuum cleaner, the filter will intercept impurities such as dust, hair, and debris. If the filter is not cleaned for a long time, these impurities will gradually accumulate and block the pores of the filter, resulting in obstruction of air circulation. Cleaning the filter can remove these blockages, allowing air to pass through the filter smoothly, thereby maintaining the strong suction of the vacuum cleaner. For example, when the filter is clogged, the vacuum cleaner may not be able to effectively suck up the dust on the ground. After cleaning, the suction is restored and various dirt can be easily cleaned. If the filter is not clean, the suction of the vacuum cleaner is weakened, and it may take multiple times of vacuuming to achieve the cleaning effect. Therefore, the device provides a vacuum cleaner with a filter that is easy to clean and scrape dust. Summary of the invention

[0009] Furthermore, the cleaning processing 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 an adjusting block, the cleaning rod passes through the upper end of the telescopic rod and is rotatably connected, and the cleaning brush is arranged on one end of the cleaning rod facing the internal filter of the vacuum cleaner.

[0010] Furthermore, the cleaning brush is arranged at an inclination and the inclination angle is consistent with the inclination angle of the filter net inside the vacuum cleaner.

[0011] Furthermore, the cleaning brush is detachably arranged on the cleaning rod.

[0012] Furthermore, the flipping device includes a flipping frame and a micro motor, wherein 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.

[0013] Furthermore, 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 is located above the driven wheel. The head end of the connecting rod is connected to the end of the flip frame. The ball device is at the end of the connecting rod. The auxiliary ring is evenly surrounded by a plurality of V-shaped grooves. The plurality of V-shaped grooves are connected and arranged end to end in sequence. The ball is located in the corresponding V-shaped groove and is slidingly matched with the V-shaped groove in a matching size.

[0014] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects: First, when there is a lot of dust on the filter screen, or when the vacuum cleaner inhales a lot of dust during the vacuuming operation, the micro motor is started to drive the cleaning rod on the output end of the micro motor to rotate, and 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, and then the mini electric cylinder is started to drive the adjusting block on the output end of the mini electric cylinder to move toward the filter screen. The movement of the adjusting block toward the filter screen drives the cleaning device to move toward the filter screen. Finally, the cleaning brush is relatively close to the surface of the filter screen. At this time, the mini electric cylinder stops running. At this time, the cleaning brush is in a state of cleaning. At this time, the driving motor drives the output end of the driving motor to move The driving wheel rotates, and the rotation of the driving wheel drives the driven wheel to rotate on the inner wall of the vacuum cleaner through the sleeve of the belt. The rotation of the driven wheel drives the adjusting device to rotate around the filter, and the rotation of the adjusting device around the filter will eventually drive the cleaning device to rotate around the filter, and the cleaning brush is in close contact with the surface of the filter, so the dust on the surface of the filter will be brushed off by the circular rotation, and the cleaning brush is in close contact with the surface of the filter to maximize the brushing force of the cleaning brush, thereby cleaning the filter with a lot of dust or scraping off the dust when the vacuum cleaner inhales a lot of dust during the vacuuming operation. The cleaning brush is rotated to a horizontal state to maximize the cleaning brush and the filter. The cleaning brush is in a state of contact with the surface area, so that the dust and impurities on the surface of the filter are optimally scraped off by the cleaning brush. The cleaning brush brushes the dust on the surface of the filter in a circular rotation manner, and the whole process is a horizontal motion state. Under this premise, the ball is located inside the corresponding V-shaped groove. Therefore, during the circular state of the cleaning brush, the ball also runs synchronously and is located in the corresponding V-shaped groove and runs synchronously. The V-shaped grooves are connected end to end in sequence, and the ball is located in the corresponding V-shaped groove and is slidably matched with the V-shaped groove in a matching size. The telescopic rod is telescopic, so that the ball not only rotates in a circular motion through the connection of the connecting rod, but also moves according to the corresponding V-shaped groove. The internal trajectory makes corresponding movements, that is, up and down reciprocating motion, thereby achieving the premise that the cleaning brush is driven to rotate in a circle to brush off the dust on the surface of the filter, while the cleaning brush is still in an up and down reciprocating motion operation state, thereby the dust and impurities that are difficult to scrape off the filter are scraped off the filter screen in an almost all-round manner through the cleaning brush, which prevents the filter from being blocked and affects the vacuuming effect. The suction force of the vacuum cleaner is weakened, and the load of the vacuum cleaner is reduced to reduce wear, so that the surface of the filter is always in a dust-free state, thereby increasing the service life and the vacuuming effect. It also reduces the repetitive work of the vacuum cleaner and reduces the load.

[0015] The cleaning brush is then pulled back and the filter is then moved back and forth until the cleaning brush is in a vertical position and the dust on the filter is removed.

[0016] Thirdly, for dust impurities that are difficult to remove on the surface of the filter or when the vacuum cleaner sucks in plastic hard objects during vacuuming, most of the plastic hard objects will collide with the filter after being sucked in, causing wear of the filter. Some smaller plastic hard objects may get stuck on the filter after colliding with the filter. 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 toward the filter. The movement of the adjustment block toward the filter drives the cleaning device to move toward the filter. Finally, after the cleaning brush is in contact with the surface of the filter, the cleaning device is driven to move by the driving motor, so that the cleaning brush is The dust on the surface of the filter is brushed off by means of circular rotation and up and down reciprocating motion. Under this premise, the micro motor is started to drive the cleaning rod on the output end of the micro motor to rotate, and the rotation of the cleaning rod drives the cleaning brush to rotate, thereby achieving a cleaning brush that rotates around the vacuum cleaner and reciprocates up and down, while also performing its own rotating dust scraping operation, thereby brushing off the dust and impurities on the surface of the filter that are difficult to remove, and being able to scrape off hard plastic objects stuck on the filter. At the same time, through this movement mode, the probability of the vacuum cleaner colliding with the filter after sucking in hard plastic objects can be reduced, thereby reducing the wear of the filter.

[0025] Preferably, the cleaning device 4 comprises 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 adjustment 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 on one end of the cleaning rod 42 facing the filter 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 11 inside the vacuum cleaner 1, and the cleaning brush 43 is detachably arranged on the cleaning rod 42; Since the cleaning brush 43 is detachably arranged, the cleaning brush 43 can be removed for cleaning or replaced when the device does not need to perform vacuuming operations, thereby improving practicality.

[0026] Preferably, the flip device 5 includes a flip frame 51 and a micro motor 52, wherein the flip frame 51 is arranged at the upper end of the telescopic rod 41, and the micro motor 52 is arranged on the flip frame 51 and the output end of the micro motor 52 is connected to the cleaning rod 42; The flipping device 5 can drive the cleaning brush 43 to rotate to change the placement state of the cleaning brush 43, so that the cleaning brush 43 can be in a vertical state, a horizontal state, an inclined state, and in short, a 360-degree state is preferred. The flipping device 5 can also drive the cleaning brush 43 to rotate continuously, so that the cleaning brush 43 can achieve different cleaning and scraping effects according to different placement states.

[0027] Preferably, the optimized cleaning device 6 comprises an auxiliary ring 61, a connecting rod 62 and a ball 63, wherein the auxiliary ring 61 is arranged on the inner side wall of the vacuum cleaner 1 and is located above the driven wheel 24, the head end of the connecting rod 62 is connected to the end of the flip frame 51, and the ball 63 is arranged at the end of the connecting rod 62, and a plurality of V-shaped grooves 611 are evenly arranged around the auxiliary ring 61, and the plurality of V-shaped grooves 611 are connected and connected in sequence end to end, and the ball 63 is located in the corresponding V-shaped groove 611 and is slidingly matched with the V-shaped groove 611 in a matching size; When there is a lot of dust on the filter 11 and the vacuum cleaner 1 sucks in a lot 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 makes the cleaning brush 43 rotate to a horizontal 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 toward the filter 11. The movement of the adjustment block 33 toward the filter 11 drives the cleaning device 4 to move toward the filter 11. Finally, the cleaning brush 43 is relatively close to the surface of the filter 11. At this time, the mini electric cylinder 32 stops running. At this time, the state of the cleaning brush 43 is as shown in FIG. Figure 5As shown, at this time, the driving motor 21 is driven to drive the driving wheel 23 on the output end of the driving motor 21 to rotate, and the driving wheel 23 rotates through the sleeve of the belt 25 to drive the driven wheel 24 to rotate on the inner wall of the vacuum cleaner 1, and the driven wheel 24 rotates to drive the adjusting device 3 to rotate around the filter 11, and the adjusting device 3 rotates around the filter 11, which will eventually drive the cleaning device 4 to rotate around the filter 11, and the cleaning brush 43 is in close contact with the surface of the filter 11, so the dust on the surface of the filter 11 will be brushed off by the circumferential rotation, and the cleaning brush 43 is in close contact with the surface of the filter 11 to maximize the cleaning effect. The cleaning brush 43 has a high brushing force, and is used to clean the filter 11 with a lot of dust, or to remove dust when the vacuum cleaner 1 inhales a large amount of dust during the vacuuming operation. The cleaning brush 43 is rotated to a horizontal state to maximize the contact area between the cleaning brush 43 and the filter 11, so as to optimally scrape off the dust and impurities on the surface of the filter 11 through the cleaning brush 43. The cleaning brush 43 brushes off the dust on the surface of the filter 11 in a circular rotation manner, and the whole process is a horizontal motion state. Under this premise, the ball 63 is located inside the corresponding V-shaped groove 611, so During the process of the cleaning brush 43 being in the circling state, the ball 63 also runs synchronously and is located in the corresponding V-groove 611 and runs synchronously. The V-grooves 611 are connected end to end in sequence, and the ball 63 is located in the corresponding V-groove 611 and is slidably matched with the V-groove 611 in a matching size. In addition, the telescopic rod 41 is telescopic, so that the ball 63 not only rotates in a circling motion through the connection of the connecting rod 62, but also makes corresponding movements according to the internal trajectory of the corresponding V-groove 611, that is, reciprocating up and down motion, thereby achieving the effect of driving the cleaning brush 43 to rotate in a circling motion. Under the premise of brushing off the dust on the surface of the filter 11, the cleaning brush 43 is still in an up and down reciprocating operation state, so that the dust and impurities that are difficult to scrape off on the filter 11 are scraped off almost in all directions by the cleaning brush 43, so as to prevent the filter 11 from being blocked, affecting the dust collection effect, weakening the suction force of the vacuum cleaner 1, and reducing the load of the vacuum cleaner 1 to reduce wear, so that the surface of the filter 1 is always in a dust-free state, thereby increasing the service life and the dust collection effect is always in a strong state, and also reducing the repetitive work of the vacuum cleaner 1 and reducing the load.

[0028] When there is less dust on the filter 11 and the vacuum cleaner 1 is not in the vacuuming operation, the cleaning rod 42 on the output end of the micro motor 52 is started to rotate, and the cleaning rod 42 rotates to drive 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, and then the adjustment block 33 on the output end of the mini electric cylinder 32 is started to move toward the filter 11. The movement of the adjustment block 33 toward the filter 11 drives the cleaning device 4 to move toward the filter 11. Finally, after the cleaning brush 43 is in contact with the surface of the filter 11, the mini electric cylinder 32 stops running. At this time, the state of the cleaning brush 43 is as shown in FIG. Figure 4 As shown, at this time, the cleaning device 4 is driven to move by the driving motor 21, so that the cleaning brush 43 is rotated in a circular manner and reciprocated up and down to brush off the dust on the surface of the filter 11, thereby achieving the scraping of dust on the surface of the filter 11. Since there is less dust on the filter 11, in order to avoid excessive and large friction between the cleaning brush 43 and the filter 11, this method can not only clean the dust on the surface of the filter 11, but also reduce the wear between the components, thereby improving the service life and dust collection effect of the vacuum cleaner 1; For dust impurities that are difficult to remove from the surface of the filter 11 or when the vacuum cleaner 1 sucks in plastic hard objects during the vacuuming operation, most of the plastic hard objects will collide with the filter 11 after the vacuum cleaner 1 sucks in the plastic hard objects, thereby causing wear of the filter 11. Some smaller plastic hard objects may get stuck on the filter 11 after colliding with the filter 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 toward the filter 11. The movement of the adjustment block 33 toward the filter 11 drives the cleaning device 4 to move toward the filter 11. Finally, after the cleaning brush 43 is in contact with the surface of the filter 11, the cleaning device 4 is driven to move by the driving motor 21, so that the cleaning The brush 43 brushes off the dust on the surface of the filter 11 in a circular rotation and up and down reciprocating motion. Under this premise, the cleaning rod 42 on the output end of the micromotor 52 is driven to rotate by starting the micromotor 52, and the rotation of the cleaning rod 42 drives the cleaning brush 43 to rotate, thereby achieving a cleaning brush 43 that rotates around the vacuum cleaner 1 and reciprocates up and down, and also performs a rotating dust scraping operation, thereby brushing off the dust and impurities on the surface of the filter 11 that are difficult to remove, and scraping off the hard plastic objects stuck on the filter 11. At the same time, through this movement mode, the probability of the vacuum cleaner 1 colliding with the filter 11 after sucking in hard plastic objects can be blocked, thereby reducing the wear of the filter 11.

[0029] Cleaning the filter 11 inside the vacuum cleaner 1 has the following effects: 1. Impact on vacuuming effect Maintain strong suction Preventing blockage: During the operation of the vacuum cleaner 1, the filter 11 will intercept impurities such as dust, hair, and debris. If the filter 11 is not cleaned for a long time, these impurities will gradually accumulate and block the pores of the filter 11, resulting in obstruction of air circulation. Cleaning the filter 11 can remove these blockages, allowing air to pass through the filter 11 smoothly, thereby maintaining the strong suction of the vacuum cleaner 1. For example, when the filter 11 is blocked, the vacuum cleaner 1 may not be able to effectively suck up dust on the ground. After cleaning, the suction power is restored and various dirt can be easily cleaned.

[0030] Optimize airflow: A clean filter 11 can ensure the normal flow of air inside the vacuum cleaner 1. Good airflow can improve the vacuuming efficiency, allowing the vacuum cleaner 1 to suck dust and debris into the dust collection bucket more quickly. Cleaning the filter 11 helps maintain the balance of airflow inside the vacuum cleaner 1 and improve the vacuuming effect.

[0031] Improve cleaning efficiency Reducing repetitive work: If the filter 11 is not clean, the suction force of the vacuum cleaner 1 is weakened, and it may take several times of vacuuming to achieve the cleaning effect. After cleaning the filter 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 room, the vacuum cleaner 1 can complete the cleaning in one go without having to repeatedly clean the same area.

[0032] 2. Impact on equipment performance and life Protecting the motor Reduce the load: A clean filter 11 can reduce the dust and impurities that enter the motor and reduce the working load of the motor. If the filter 11 is clogged, 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 11 can protect the motor and extend the service life of the vacuum cleaner 1.

[0033] Reduce wear and tear: When dust and impurities enter the motor, they will cause wear and tear on the internal components of the motor. Cleaning the filter 11 can prevent these impurities from entering the motor, reduce the wear and tear of the motor, and improve the reliability and stability of the motor.

[0034] Maintain stable equipment performance Ensure normal operation: The filter 11 is an important part of the vacuum cleaner 1, and its cleanliness directly affects the overall performance of the vacuum cleaner 1. If the filter 11 is not clean, it may cause various malfunctions of the vacuum cleaner 1, such as reduced suction, increased noise, abnormal heating, etc. Regular cleaning of the filter 11 can ensure that the vacuum cleaner 1 always maintains a good performance state and stable operation.

[0035] Prolong service life: By cleaning the filter 11, damage to other parts 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 the equipment, but also reduces the generation of electronic waste, which is more environmentally friendly.

[0036] 3. Impact on Indoor Air Quality Filtered air Removing fine dust and allergens: The filter 11 of the vacuum cleaner 1 can not only intercept large particles of dust and debris, but also filter tiny particles in the air, such as pollen, dust mites, bacteria and other allergens. Cleaning the filter 11 can ensure the filtering effect of the filter 11, reduce the content of these allergens in the indoor air, and improve the indoor air quality, which is particularly important for people with allergies.

[0037] Release clean air: The clean filter 11 can filter the inhaled air before discharging it, releasing relatively clean air. This helps reduce dust and pollutants in the indoor air, making the indoor environment fresher and healthier. For example, when cleaning a closed space such as a bedroom, the cleaned vacuum cleaner 1 can effectively improve the indoor air quality and enhance the living comfort.

For those skilled in the art, the present invention may have various modifications and variations.
