Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a vacuum cleaner filter vibration device. Background Technology

[0002] A vacuum cleaner is a device used to collect dust. As described in publication number CN218960621U, its main principle is to use negative pressure to suck dust into a dust collection bin, thereby achieving the function of collecting dust.

[0003] However, after a vacuum cleaner has been working for a long time, dust will accumulate on the filter, which will reduce the vacuuming effect. Currently, the operator stops vacuuming when he notices that the suction power has decreased, turns on the vacuum cleaner to clean the filter, and then resumes vacuuming.

[0004] Such a shutdown cleaning process affects vacuuming efficiency. Furthermore, when the vacuum cleaner is turned on and the filter is removed for cleaning, the dust on the filter will be dispersed into the air again, thus causing secondary pollution of the surrounding air. Therefore, a device that can automatically clean the filter is needed. Utility Model Content

[0005] After a vacuum cleaner has been working for a while, dust will accumulate in the dust collection bin and adhere to the filter screen. Disassembling and cleaning the filter screen will cause the dust accumulated on the filter screen to be dispersed into the surrounding air again, causing air pollution.

[0006] This invention addresses the shortcomings of existing technologies by providing a vacuum cleaner filter vibration device.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: it includes a mounting base, on which a filter unit and a vibration unit are mounted. When the vibration unit is activated, it acts directly or indirectly on the filter unit to shake off the dust on the filter unit.

[0008] Its beneficial effect is that when dust accumulates on the filter unit, the vibration unit drives the filter unit to vibrate, thereby shaking off the dust on the filter unit and thus playing the role of automatically cleaning the filter unit.

[0009] In the above scheme, preferably, the filter unit includes a filter element and a filter frame. The filter element is assembled on the mounting base through the filter frame to filter the dust sucked in by the negative pressure unit.

[0010] In the above scheme, preferably, a detection unit is also included. The detection unit is installed on the mounting base and is used to identify the dust adhesion status on the filter unit. When the dust adhesion reaches a set amount, the vibration unit is activated.

[0011] In the above scheme, preferably, the detection unit is a vacuum or flow detector, which identifies the dust adhesion status on the filter unit by detecting the vacuum or flow rate flowing through the filter unit.

[0012] Its beneficial effect is that by detecting the wind speed or flow rate, the dust accumulation status on the filter screen can be determined, and when the wind speed or flow rate drops to the set value, the vibration unit is activated to clean the dust on the filter screen unit.

[0013] In the above scheme, preferably, the mounting base has a recessed cavity for mounting the vibration unit, and the vibration unit is a vibration motor or an electromagnetic vibrator.

[0014] In the above scheme, preferably, the outer end face of the bottom of the recessed cavity abuts against the filter unit.

[0015] In the above scheme, preferably, the outer end face of the bottom of the recessed cavity abuts against the mesh surface of the filter element.

[0016] In the above scheme, preferably, the vibration unit is an eccentric wheel motor.

[0017] In the above scheme, preferably, the filter element is provided with an annular clamping member, and the filter frame is provided with an annular positioning groove. The filter element is positioned and assembled in the annular positioning groove of the filter frame by the annular clamping member. When the filter frame is assembled on the mounting base, the annular clamping member on the filter element presses against the bottom surface of the mounting base.

[0018] In the above scheme, preferably, one side of the filter frame is rotatably mounted on the mounting base by a pin, and the other side is locked onto the mounting base by a snap-fit.

[0019] The beneficial effects of this utility model are: This utility model provides a vacuum cleaner filter vibration device, which can drive the filter unit to vibrate together through the vibration of the vibration unit, thereby automatically shaking off the dust accumulated on the filter unit. At the same time, it can also judge the status of the filter unit by the detection unit, and then start the vibration unit to clean the filter unit in a timely manner. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0029] Example 1:

[0030] See Figures 1-8 The vacuum cleaner includes a dust collection bin 4, a mounting base 1, and a negative pressure unit 5. The negative pressure unit 5 is assembled to the upper surface of the mounting base 1 by fasteners. The dust collection bin 4 is used to collect and store the sucked-in dust. The mounting base 1 is assembled on the upper opening of the dust collection bin 4, thereby sealing the upper opening of the dust collection bin 4. The mounting base 1 has an air intake 13. The negative pressure unit 5 can generate negative pressure after being started. The negative pressure unit 5 is a vacuum generator or a suction motor. The negative pressure unit 5 is connected to the air intake 13, thereby generating negative pressure at the air intake 13 when it is started, so that the air in the dust collection bin 4 is sucked into the air intake 13. The dust collection bin 4 is connected to a suction pipe, which collects the dust from the outside into the dust collection bin 4.

[0031] A vacuum cleaner filter vibration device includes a filter unit 2 and a vibration unit 3, both of which are mounted on a mounting base 1. The filter unit 2 includes a filter element 22 and a filter frame 21. One side of the filter frame 21 is rotatably mounted on the bottom surface of the mounting base 1 via a pin, and the other side is equipped with a snap-fit ​​cantilever 212. The snap-fit ​​cantilever 212 is elastically deformable and is equipped with a snap-fit ​​hook 213. The bottom surface of the mounting base 1 has an upwardly concave snap-fit ​​cavity 1. 5. A snap-fit ​​limiting plate 151 is provided on the snap-fit ​​cavity 15, and an annular positioning groove 211 for positioning the filter screen component 22 is also provided on the filter screen frame 21. The filter screen component 22 includes a mesh surface 222 for filtering. An annular pressing member 221 is provided at the upper position of the mesh surface 222 in the circumferential direction. The annular positioning groove 211 on the filter screen frame 21 is adapted to the annular pressing member 221. The filter screen component 22 is positioned and installed on the annular positioning groove 211 of the filter screen frame 21 by the annular pressing member 221.

[0032] After the filter element 22 is installed on the filter frame 21, one end of the filter frame 21 with the snap-fit ​​arm 212 rotates upward. After the snap-fit ​​arm 212 is inserted into the snap-fit ​​cavity 15, the snap-fit ​​hook 213 is snapped onto the snap-fit ​​limiting plate 151. At this time, the annular pressing part 221 of the filter element 22 is pressed and set on the bottom surface of the mounting base 1 under the action of the filter frame 21. The filter element 22 covers the air intake 13, so that the air entering the air intake 13 from the dust collection bin 4 is filtered by the filter element 22, and the dust sucked in by the vacuum cleaner is concentrated in the dust collection bin 4.

[0033] The lower end face of the mounting base 1 is provided with an annular mounting surface 12 that cooperates with the annular pressure member 221. An upper concave cavity 14 is provided in the annular area of ​​the annular mounting surface 12, and an air intake 13 is provided on the upper end face of the upper concave cavity 14. At the same time, a lower concave cavity 11 is also provided in the annular area of ​​the annular mounting surface 12, which is in the opposite direction to the concavity of the upper concave cavity 14. The lower concave cavity 11 is located in the middle of the annular area. When the filter screen 22 is assembled on the mounting base 1, the outer end face of the lower concave cavity 11 abuts against the mesh surface 222 of the filter screen 22.

[0034] The outer end face of the concave cavity 11 abuts against the middle of the mesh surface 222, so that the concave cavity 11 can directly act on the mesh surface 222 when it vibrates, thereby causing the mesh surface 222 to vibrate together.

[0035] The filter frame 21 presses against the lower end face of the annular pressure member 221 of the filter element, so that the upper end face of the annular pressure member 221 presses against the annular mounting surface 12. The filter frame 21 is fixed to the mounting base 1 by fasteners, thereby sealing the connection between the annular pressure member 221 and the annular mounting surface 12. The annular pressure member 221 is made of elastic material. When the annular pressure member 221 is pressed against the annular mounting surface 12, the annular mounting surface 12 will elastically deform, thereby sealing the connection with the annular mounting surface 12.

[0036] In this embodiment, the mounting base 1 is provided with two air intakes 13, and the two air intakes are located on the left and right sides of the lower concave cavity 11 respectively. When the negative pressure unit 5 is activated, the upper concave cavity 14 becomes negative pressure, and air enters the upper concave cavity 14 through the mesh surface 222, while dust is filtered and blocked by the mesh surface 222 and cannot enter the upper concave cavity 14.

[0037] The vibration unit 3 can be an electromagnetic vibrator or a vibration motor. The vibration unit 3 is fixedly configured in the recessed cavity 11 by fasteners. Both can drive the recessed cavity 11 to vibrate. When it is a vibration motor, it is preferred to be a vibration motor with eccentric blocks at both ends of the rotor shaft.

[0038] When the vibration unit 3 is activated, it causes the recessed cavity 11 to vibrate together. Since the recessed cavity 11 is located in the middle of the mounting base 1, the vibration spreads outward when the recessed cavity 11 vibrates, causing the entire mounting base 1 to vibrate together. The vibration amplitude at the recessed cavity 11 is greater than the vibration amplitude at the outer edge of the mounting base 1. In normal use, the outer edge of the mounting base 1 is fixedly mounted on the vacuum cleaner, so the vibration amplitude at the outer edge is weakened or does not vibrate. The vibration amplitude decreases from the recessed cavity 11 outward.

[0039] The outer end face of the recessed cavity 11 abuts against the mesh surface 222 of the filter screen 22. Therefore, when the vibration unit 3 starts to vibrate, the mesh surface 222 vibrates under the drive of the recessed cavity 11, thereby causing the dust on the mesh surface 222 to fall off.

[0040] The filter screen 22 is fixedly installed on the mounting base 1, and the annular mounting surface 12 is in contact with the filter screen 22. The annular mounting surface 12 is located outside the recessed cavity 11 on the mounting base 1, so the vibration amplitude of the recessed cavity 11 is greater than that of the annular mounting surface 12, and the annular pressing member 221 will also vibrate. The vibration amplitude and frequency of the screen 222 are different from those of the annular pressing member 221, so relative vibration will also occur between the two, thereby enhancing the dust collection effect.

[0041] Example 2:

[0042] See Figures 1-8 In this embodiment, the following further improvements are made based on embodiment 1: a detection unit is also included, which may be a vacuum degree and / or flow detector for detecting the vacuum degree and / or flow rate of the fluid. In this embodiment, the detection unit is set on the air intake 13, or it may be set on the main air outlet.

[0043] In the initial state, the vibration unit 3 is in the off state. When the wind speed and / or flow rate of the air intake 13 decreases, it is determined that the filter screen 22 is blocked by dust, which affects the passage of air. At this time, the vibration unit 3 is activated to shake off the dust on the filter screen 22. When the wind speed and / or flow rate of the air intake 13 recovers, the vibration unit 3 is controlled to be turned off.

[0044] It can also start the vibration unit 3 in the initial state and adjust the vibration frequency and / or amplitude in real time according to the wind speed and / or flow rate data of the air intake 13. When the wind speed and / or flow rate decreases, the vibration frequency and / or amplitude is increased, and when the wind speed and / or flow rate recovers, the vibration frequency and / or amplitude is controlled to decrease.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
