All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The dust filtering bin and the dust collector of the present utility model will be described with reference to fig. 1 to 4.

As shown in fig. 1 to 4, an embodiment of the present utility model provides a dust filtering bin, which includes a cover 110, a dust bin body 210, a hepa cover 220, and an air deflector 240. Wherein, the cover 110 is provided with a first air inlet 111; the dust bin body 210 is detachably connected with the cover body 110, the dust bin body 210 is provided with a second air inlet 211, and the second air inlet 211 is in fluid communication with the first air inlet 111; the air deflector 240 is connected to the hepa cover 220, the position of the start end of the air deflector 240 corresponds to the second air inlet 211, and the air deflector 240 extends spirally toward the direction approaching the cover 110.

According to the dust filtering bin provided by the embodiment of the utility model, the air deflector 240 is arranged, the position of the initial end of the air deflector 240 corresponds to the second air inlet 211, and the air deflector 240 spirally extends towards the direction close to the cover body 110, so that when wind flows from the second air inlet 211 into the dust bin, the wind can spirally rise under the guidance of the air deflector 240, and centrifugal force is generated during the rising, so that dust rotates to the upper part along the inner wall of the dust bin body 210, and the blockage caused by accumulation of sundries at a sea Pa is avoided. Meanwhile, negative pressure can be formed inside the HEPA cage 220, so that suction force is increased, and better cleaning effect is obtained.

Specifically, the cover 110 is located at the top of the dust filtering bin, and is used to cooperate with the dust bin body 210 to form a dust collecting space. The cover 110 is provided with a first air inlet 111, and the direction from the cover 110 to the dust bin body 210 is suitable for the air flow entering through the first air inlet 111, and meanwhile, outside dust and sundries are carried in together, so that the aim of smoothly sucking dust is achieved, and a good cleaning effect is achieved.

The dust bin body 210 is detachably connected with the cover 110, and when the dust bin body 210 is matched with the cover 110, the inside of the dust bin body 210 can be used for dust collection. The dust bin body 210 is provided with a second air inlet 211, and the second air inlet 211 is in fluid communication with the first air inlet 111. Through the arrangement, the wind flow carrying sundries and dust can enter from the first air inlet 111 and pass through the second air inlet 211 to finally enter the dust bin body 210, so that the dust collection function is realized.

Further, the center line of the first air inlet 111 and the center line of the second air inlet 211 are disposed at an angle and are different-plane straight lines.

The center line of the first air inlet 111 and the center line of the second air inlet 211 are disposed at an angle, that is, the air inlet directions of the first air inlet 111 and the second air inlet 211 are different. Specifically, in the present embodiment, the first air inlet 111 vertically introduces the air flow along the direction from the cover 110 to the dust bin body 210; the second air inlet 211 continuously introduces the air flow into the dust bin body 210 along the direction perpendicular to the axis of the dust bin body 210, in other words, when the external sundries and dust enter from the first air inlet 111, the external sundries and dust enter into the dust bin body 210 again through the direction change of the second air inlet 211. By this arrangement, foreign matters and dust outside are prevented from being directly blown to the HEPA cover 220, and accumulation of the foreign matters and dust at the position of the HEPA cover 220 is prevented. Of course, in other embodiments, the air guiding directions of the first air inlet 111 and the second air inlet 211 may be set in other manners to achieve the above purpose.

The center line of the first air inlet 111 and the center line of the second air inlet 211 are different-plane straight lines, that is, the center lines of the first air inlet 111 and the second air inlet 211 are not in the same plane. The wind flow entering from the first air inlet 111 is at least partially deflected along the circumference of the dust bin body 210 while passing through the second air inlet 211. In this embodiment, when the front of the observer faces the connection between the cover 110 and the dust bin body 210 and the first air inlet 111 is disposed at the position closest to the connection, it can be observed that the second air inlet 211 is disposed at the right lower portion of the dust bin body 210, and the area of the second air inlet is approximately half of the area of the first air inlet 111. By such arrangement, the air flow entering from the first air inlet 111 can have a rightward rotation trend when passing through the second air inlet 211, so that the smooth air guiding of the subsequent air guiding plate 240 is facilitated.

In this embodiment, the cover 110 is hinged to the dust bin body 210, and the cover 110 and the dust bin body 210 are connected by a clamping structure 310.

As shown in fig. 1, the cover 110 is hinged to the dust bin body 210. Meanwhile, a clamping structure 310 is disposed between the cover 110 and the dust bin body 210, and the clamping structure 310 is used for sealing and connecting the cover 110 and the dust bin body 210 when the cover 110 is matched with the dust bin body 210. The fastening structure 310 may be a buckle, or may be another element capable of realizing fastening, so long as the cover 110 and the dust bin body 210 can be connected in a sealing manner, which is not limited in this embodiment. Preferably, the clamping structure 310 is disposed opposite to the hinge position of the cover 110 and the dust bin body 210, so as to perform a better sealing connection function.

Further, a spring may be further provided between the clamping structure 310 and the cover 110 or between the clamping structure 310 and the dust bin body 210. By such arrangement, when the locking structure 310 is pressed down, the internal spring is compressed and contracted, so that the locking structure 310 is lifted up at a side far away from the spring, and the locking between the cover 110 and the dust bin body 210 can be conveniently released. Therefore, when a user needs to clean the dust collected in the dust bin body 210, the user can open the cover by pressing the clamping structure 310 to pour the dust, so that the use convenience is greatly improved.

The wind deflector 240 is connected to the hepa cover 220 and functions to guide the direction of the wind flow. In this embodiment, the hepa cover 220 is integrally formed with the air deflector 240. By the arrangement, structural parts can be reduced, production steps are simplified, cost saving is achieved, and large-scale industrial production is facilitated.

The position of the start end of the air deflector 240 corresponds to the second air inlet 211, and the air deflector 240 extends spirally toward the direction approaching the cover 110.

After the air flow enters the dust bin body 210 from the second air inlet 211, the air flow needs to be spirally lifted under the guidance of the air deflector 240, and therefore, the initial end position of the air deflector 240 is set to correspond to the second air inlet 211. The wind deflector 240 is spirally extended toward a direction close to the cover body 110, so that wind flows upward to be rotated and simultaneously generate centrifugal force, so that dust is rotated to the upper side along the inner wall of the dust bin body 210, thereby avoiding blockage caused by accumulation of sundries at the sea kerchief. Meanwhile, negative pressure can be formed inside the HEPA cage 220, so that suction force is increased, and better cleaning effect is obtained.

Specifically, along the edge of the second air inlet 211, the start end of the air deflector 240 is formed at one side of the second air inlet 211 near the first air inlet 111. In other words, when the air flow enters the dust bin body 210 from the second air inlet 211, the air flow is located below the air deflector 240, and then spirally rises along the inner wall of the dust bin body 210 against the bottom surface of the air deflector 240. Therefore, smooth ventilation of wind can be realized, and the dust filtering bin can better absorb dust. Preferably, an air deflector 240 may be disposed along the edge of the second air inlet 211 at the left side of the second air inlet 211 to prevent the air from rotating in the opposite direction.

According to an embodiment of the present utility model, the dust filtering bin further includes a filter plate 320, where the filter plate 320 is disposed between the first air inlet 111 and the second air inlet 211.

As shown in fig. 2, a filter plate 320 is disposed between the first air inlet 111 and the second air inlet 211 to primarily filter the impurities of large particles, and prevent blocking of the air guide path, particularly, the second air inlet 211. In this embodiment, the filter plate 320 is disposed between the cover 110 and the dust bin body 210, so that the filter plate 320 can be fixed by matching the cover 110 with the dust bin body 210.

According to the dust filtering bin provided by the embodiment of the utility model, the HEPA cover 220 is provided with a filtering opening.

The hepatica 220 is fixed to the bottom of the dust bin body 210 for covering the hepatica. The HEPA cover 220 is provided with a filtering opening, so that impurities with larger particles can be primarily separated, and blockage at the HEPA can be prevented. Meanwhile, the negative pressure inside the HEPA cage 220 can generate suction force to enhance cleaning effect.

Specifically, the filtering ports may be arranged in two ways:

mode one: the filtering mouth is formed as a first through hole 221 opened on a sidewall of the hepa cover 220.

As shown in fig. 4, the filtering openings are formed as a plurality of first through holes 221 opened on the sidewall of the hepa cover 220, and distributed in multiple layers along the circumference of the hepa cover 220. This arrangement can make the contact area of the wind flow and the first through hole 221 larger and the contact position more uniform, thereby achieving the effect of more sufficient filtration.

Mode two: the filtering opening is formed as a notch formed on the side wall of the hepa cover 220, a filter screen is arranged on the hepa cover 220 at a position corresponding to the notch, and a second through hole is formed on the filter screen.

The filter openings are formed as large cuts that open into the sidewall of the hepa housing 220. In this embodiment, the incision is formed on the side of the hepa cover 220 facing away from the air deflector 240, so as to avoid affecting the air guiding effect of the air deflector 240. The filter screen is arranged at the position corresponding to the notch, the second through holes are formed in the filter screen, and the second through holes are uniformly distributed on the filter screen, so that dust can be filtered more comprehensively and efficiently, and the cleaning times of the HEPA are effectively reduced. The filter screen can be made of steel mesh, and of course, other materials can be selected on the premise of not affecting the filtering effect, and the embodiment is not limited to the above.

Preferably, the aperture of the second through hole is set smaller than that of the first through hole 221, so that dust and foreign matters can be filtered more finely, so that dust particles directly contacting the sea paper are further reduced, thereby reducing the cleaning times of the sea paper and prolonging the service life of the sea paper.

The embodiment of the utility model also provides a dust collector which comprises the dust filtering bin.

According to the dust collector provided by the embodiment of the utility model, the air deflector 240 is arranged, the position of the initial end of the air deflector 240 corresponds to the second air inlet 211, and the air deflector 240 spirally extends towards the direction close to the cover body 110, so that when wind flows from the second air inlet 211 into the dust bin, the wind can spirally rise under the guidance of the air deflector 240, and centrifugal force is generated during the rising, so that dust rotates to the upper part along the inner wall of the dust bin body 210, and the blockage caused by accumulation of sundries at a sea Pa is avoided. Meanwhile, negative pressure can be formed inside the HEPA cage 220, so that suction force is increased, and better cleaning effect is obtained.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
