Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dust bag vacuum cleaners, specifically a novel flow-guiding and anti-clogging filter dust bag mechanism. Background Technology
[0002] Bag vacuum cleaners are widely used in household cleaning both domestically and internationally due to their ease of operation, high dust bag removal efficiency, convenient replacement, low cost, and portability. Their working principle involves the continuous replenishment of air from the front suction section of the fan, creating a momentary vacuum inside the vacuum cleaner. This vacuum, combined with the external atmospheric pressure, draws air into the dust bag, where dust and other debris are trapped. The air, purified by the filter, is then discharged from the rear of the machine. The battery pack provides power to the motor; nowadays, for easier charging, most models feature removable battery packs, and the connection methods between these removable battery packs and the main body vary.
[0003] In existing technologies, most methods for improving the dust removal efficiency of bagged vacuum cleaners are not good, and the dust bags are not easy to replace, while the operating cost is high. Therefore, we propose a new type of flow-guiding and anti-clogging filter dust removal dust bag mechanism. Utility Model Content
[0004] The purpose of this invention is to provide a novel flow-guiding and anti-clogging filter dust bag mechanism to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A novel flow-guiding and anti-clogging filter dust bag mechanism includes a body, a front cover inside the body, a dust bag holder at the left end of the front cover, a dust bag inside the front cover on the dust bag holder, a front head at the left end of the dust bag holder, a check valve on the dust bag holder, an air intake grille on the right side inside the body, and a brushless motor on the right side of the air intake grille inside the body.
[0007] As a further embodiment of this utility model: the air intake grille is evenly provided with a number of protruding mechanisms and side air intakes.
[0008] As a further improvement of this utility model, the front cover of the machine body is also evenly provided with a number of air guide holes.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. The machine features a front cover with numerous air vents, an air intake grille with air inlets on both the side and front, and a check valve. During operation, simply turning on the power button starts the machine; the check valve opens, and the dust bag begins collecting dust and debris. Turning off the machine closes the check valve. After the machine starts, the dust bag fills the inside of the front cover and the front of the air intake grille during dust and debris collection. The protruding structures of the air vents on the front cover and the air intake grille, along with the side air inlets, ensure that the dust bag does not clog the front cover or air intake grille during dust and debris collection, preventing malfunctions such as motor blockage. This increases the efficiency and frequency of dust and debris collection, extending the machine's lifespan.
[0011] 2. It also makes it easier for users to replace the dust bag, improving the efficiency of the device and reducing its operating costs. Attached Figure Description

[0015] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.
[0016] Example
[0017] Please see Figures 1-2In this embodiment of the utility model, a novel flow-guiding and anti-clogging filter dust bag mechanism includes a body 6, a front cover 5 inside the body 6, a dust bag holder 3 at the left end of the front cover 5, a dust bag 4 inside the front cover 5 on the dust bag holder 3, and a front head 1 at the left end of the dust bag holder 3. When the device is in actual use, the internal mechanism of the body 6 generates suction, which allows dust and other particles to enter the dust bag 4 through the front head 1, thereby achieving the filtration of dust. At the same time, the dust bag 4 can be easily replaced by disassembling the dust bag holder 3, thus ensuring the efficiency of the device.
[0018] The dust bag holder 3 is also equipped with a check valve 2. Under the action of the check valve 2, the dust that enters the dust bag 4 cannot flow back, thereby ensuring the efficiency of the device to a certain extent.
[0019] An air intake grille 7 is also provided on the right side inside the body 6. The air intake grille 7 is evenly provided with several protruding mechanisms 701 and side air inlets 702. The front cover 5 of the body is also evenly provided with several air guide holes 501. When the machine is started, during the garbage and dust collection process, the dust bag 4 fills the inside of the front cover 5 of the body and the front of the air intake grille 7. The air guide holes 501 on the front cover 5 of the body and the protruding mechanisms 701 and side air inlets 702 of the air intake grille 7 can ensure smooth and unobstructed airflow during garbage and dust collection, ensuring that the dust bag 4 will not block the air inlet, thereby avoiding malfunctions such as motor blockage. When the dust bag 4 accidentally blocks the air intake grille 7, the air intake channel formed by the space between the front cover 5 of the body and the body 6 and the side air inlets 702 of the air intake grille 7 can also ensure the normal use of the dust bag 4, ensuring the high efficiency and frequency of use of the dust bag in collecting garbage and dust, and enhancing the service life of the machine.
[0020] Inside the body 6, a brushless motor 8 is also installed on the right side of the air intake grille 7. Under the action of the brushless motor 8, the device is provided with good power support during operation. At the same time, the brushless motor 8 has a series of excellent characteristics such as small size, light weight, low loss, low heat generation, high efficiency, good speed regulation performance, low noise, stable operation, high reliability, long life and energy saving, which to a certain extent ensures the efficiency of the device.
[0021] In actual use, the machine is started by pressing the power switch. Check valve 2 opens, and debris and dust enter the dust bag 4 from the front of the machine head 1 along the air intake direction. The dust bag 4 begins collecting dust and various debris along the air intake direction. When the machine is turned off, check valve 2 closes. During the debris and dust collection process after the machine starts, the dust bag 4 fills the inside of the front cover 5 and the front of the air intake grille 7. The numerous air guide holes 501 on the front cover 5 and the protruding mechanism 701 of the air intake grille 7, along with the side air intake 702, ensure smooth and unobstructed airflow during debris and dust collection, preventing the dust bag 4 from clogging the air intake and thus avoiding malfunctions such as motor blockage. Even if the dust bag 4 accidentally clogs the air intake grille 7, the space between the front cover 5 and the machine body 6, and the air intake channel formed by the side air intake 702 of the air intake grille 7, ensure the normal operation of the dust bag 4.
[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
