Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaner trimming devices, specifically a trimming device for vacuum cleaners. Background Technology

[0002] Vacuum cleaners can be used to clean dust and dander from the surfaces of furniture such as sofas and beds. For example, fabric sofas are prone to accumulating dust and human skin flakes, and vacuum cleaners can effectively remove these dirt, extend the life of the sofa, and improve indoor air quality. For furniture such as bookshelves and wardrobes, vacuum cleaners can remove dust from the surface and crevices, preventing dust accumulation from damaging the furniture.

[0003] A hair-cutting device is needed during the use of a vacuum cleaner. Chinese utility model patent CN216754342U discloses a hair-prevention device for a vacuum cleaner floor brush. The device includes a connector embedded in the rear end of the vacuum cleaner floor brush shell, grooves on both sides of the front of the vacuum cleaner floor brush shell with rollers movably connected inside the grooves, and an adsorption groove on the front of the vacuum cleaner floor brush shell with iron plates embedded in the upper and lower front ends of the inner wall of the adsorption groove. With the installation of hooks, when dust and hair are sucked into the adsorption groove during vacuum cleaner operation, the hair is easily hooked by the hooks. The angled hooks do not easily block the adsorbed dust and impurities. When cleaning the hooks is needed, the user can pull a scraper, which moves along the shape of the hooks to separate the hair attached to the outside of the hooks, preventing the hair from being sucked into the vacuum cleaner and tangling on the filter side, while also facilitating hair cleaning.

[0004] This invention makes it less likely for hair to be sucked into the vacuum cleaner and get tangled in the filter. However, it cannot scrape off debris or cut the hair, which means that debris and hair may still remain on the floor brush, requiring manual cleaning by staff, which is quite troublesome. Therefore, a hair-cutting device for vacuum cleaners is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that existing hair-cutting devices cannot scrape away debris and cut hair, resulting in debris and hair remaining on the floor brush, requiring manual cleaning by staff, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hair-cutting device for a vacuum cleaner includes a hair-cutting frame, the inner side of which is provided with a cleaning component for scraping away debris and cutting hair;

[0008] The cleaning assembly includes a motor fixedly connected to the top of the trimming frame, a lead screw fixedly connected to the output shaft of the motor, a lifting plate threaded onto the outer surface of the lead screw, a sleeve fixedly connected to the inner side of the trimming frame, a frame fixedly connected to the bottom of the lifting plate, electric push rods fixedly connected to both sides of the frame, movable blocks fixedly connected to the output shaft of the electric push rods, two limiting rods fixedly connected to the inner side of the frame, a scraping blade fixedly installed at the bottom of the movable block, and an air-blowing limiting assembly provided on the outer side of the trimming frame to prevent debris and hair from flying upwards.

[0009] Furthermore, the air blowing limiting assembly includes blowers fixedly installed on the left and right sides of the cutting frame, air collection boxes fixedly connected to the left and right sides of the bottom of the cutting frame, a delivery pipe fixedly connected to the outside of the blowers, and an air outlet fixedly connected to the outside of the air collection boxes.

[0010] Furthermore, the delivery pipe is connected to the gas collection box, and several nozzles for jetting are fixedly connected to the outer surface of the gas exhaust.

[0011] Furthermore, a dustproof net is provided on the outside of the blower, and the air exhaust is arranged at an angle.

[0016] Compared with the prior art, the present invention provides a hair-cutting device for a vacuum cleaner, which has the following beneficial effects:

[0017] 1. This hair-cutting device for vacuum cleaners, through the inclusion of a cleaning component, automatically scrapes away debris and cuts hair from the outer surface of the floor brush. When cleaning is needed, the motor drives the lead screw to rotate clockwise, which, under the limiting action of the sleeve, causes the lifting plate to move the frame and the integrated scraping blade vertically downwards. This allows the bottom end of the integrated scraping blade, similar to a scraper, to press against the floor brush to scrape away debris from its outer surface. During this process, the electric push rod pushes the integrated scraping blade through the movable block, enabling the blade to move laterally. The sharp edge of the integrated scraping blade then cuts the hair on the outer surface of the floor brush. Finally, the remaining debris and hair on the floor brush are thoroughly cleaned, eliminating the need for manual cleaning by personnel, making it quite convenient.

[0018] 2. The hair-cutting device for vacuum cleaners, by setting an air-blowing limiting component, allows the blower to blow airflow into the air-gathering box. During this process, the delivery pipe can guide the airflow into the exhaust pipe. Finally, through several nozzles on the outer surface of the exhaust pipe, the airflow is blown out in an inclined state, thereby preventing debris from flying upwards and affecting the normal operation of the cleaning components.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 The hair-cutting device for a vacuum cleaner in this embodiment includes a hair-cutting frame 1, and a cleaning component for scraping off debris and cutting hair is provided on the inner side of the hair-cutting frame 1.

[0025] The cleaning assembly includes a motor 2 fixedly connected to the top of the trimming frame 1. The output shaft of the motor 2 is fixedly connected to a lead screw 3. A lifting plate 4 is threadedly connected to the outer surface of the lead screw 3. A sleeve 5 is fixedly connected to the inner side of the trimming frame 1. A frame 6 is fixedly connected to the bottom of the lifting plate 4. Electric push rods 7 are fixedly connected to both sides of the frame 6. A movable block 8 is fixedly connected to the output shaft of the electric push rod 7. Two limit rods 9 are fixedly connected to the inner side of the frame 6. A scraping blade 10 is fixedly installed at the bottom of the movable block 8. An air-blowing limit assembly is provided on the outer side of the trimming frame 1 to prevent debris and hair from flying upwards. When cleaning is required, the motor 2 can drive the lead screw 3 to rotate clockwise. Under the limiting action of the sleeve 5, the lifting plate 4 drives the frame 6 and the scraping blade 10 to move vertically downwards. The scraping blade 10, which is similar to a scraper, then presses its bottom end against the floor brush to scrape away debris from its outer surface.

[0026] During this process, the electric push rod 7 can push the integrated scraping blade 10 through the movable block 8, so that the integrated scraping blade 10 can move laterally, thereby using the sharp edge of the integrated scraping blade 10 to cut the hair on the outer surface of the floor brush, and finally, thoroughly cleaning the debris and hair remaining on the floor brush.

[0027] It should be noted that this application can use a synchronization controller or other synchronization device to ensure that the output shafts of the two electric push rods 7 extend and retract simultaneously, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, so they will not be described in detail in the specific embodiments.

[0028] In this embodiment, the air blowing limiting component includes blowers 11 fixedly installed on the left and right sides of the trimming frame 1. Air collection boxes 12 are fixedly connected to the left and right sides of the bottom of the trimming frame 1. A conveying pipe 13 is fixedly connected to the outside of the blowers 11, and an air outlet 14 is fixedly connected to the outside of the air collection box 12. The conveying pipe 13 is connected to the air collection box 12. Several nozzles for air jetting are fixedly connected to the outer surface of the air outlet 14. The blowers 11 can blow airflow into the interior of the air collection box 12. During this process, the conveying pipe 13 can guide the airflow into the air outlet 14. Finally, through the several nozzles for air jetting on the outer surface of the air outlet 14, an inclined airflow is blown out, thereby preventing debris from flying upwards and affecting the normal operation of the cleaning component.

[0029] It should be noted that the blower 11 is equipped with a dustproof net on its exterior, and the exhaust 14 is set at an angle. The dustproof net of the blower 11 can prevent debris from being sucked into its interior.

[0030] Specifically, the lifting plate 4 is slidably connected to the sleeve 5, and the movable block 8 is slidably connected to the limiting rod 9. The limiting rod 9 and the sleeve 5 can play a role in sliding and limiting, thereby improving stability.

[0031] It should be noted that the output shaft of motor 2 passes through the cutting frame 1 and extends to its inner side, and the output shaft of electric push rod 7 passes through the frame 6 and extends to its inner side.

[0032] Specifically, a connector 15 is fixedly connected to the back of the trimming frame 1. A threaded post 16 is threadedly connected to the top of the connector 15. A knob 17 is fixedly connected to the top of the threaded post 16. A threaded hole matching the threaded post 16 is opened on the top of the connector 15. By setting the connector 15, the threaded post 16 and the knob 17, the trimming device can be fixed to the vacuum cleaner, and the position of the integrated scraping blade 10 is directly above the floor brush. The operator holds the connector 15 against the protruding position of the vacuum cleaner, and then turns the knob 17 clockwise, which will drive the threaded post 16 to rotate clockwise and move vertically downward, thereby threading the threaded post 16 into the threaded hole of the vacuum cleaner for positioning.

[0033] The working principle of the above embodiments is as follows:

[0034] When cleaning is needed, start and control motor 2, which will drive screw 3 to rotate clockwise. Under the limiting action of sleeve 5, lifting plate 4 will drive frame 6 and scraping blade 10 to move vertically downwards. The scraping blade 10, similar to a scraper, will then press its bottom end against the floor brush to scrape away debris from its outer surface. During this process, start electric push rod 7, which will push scraping blade 10 through movable block 8, allowing it to move laterally. The sharp edge of scraping blade 10 will then cut the hair on the outer surface of the floor brush, ultimately cleaning the floor thoroughly. After brushing away any remaining debris and hair, the blower 11 is activated during the cleaning process to blow airflow into the air collection box 12. Meanwhile, the delivery pipe 13 guides the airflow into the air outlet 14. Finally, through several nozzles on the outer surface of the air outlet 14, the airflow is blown out at an angle to prevent debris from flying upwards and affecting the normal operation of the cleaning components. After cleaning is completed, the electric push rod 7 is turned off, and the output shaft of the motor 2 is controlled to rotate counterclockwise. This causes the lifting plate 4 to move the frame 6 and the integrated scraping blade 10 vertically upwards, thereby resetting them.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
