Description

Dust-gas separating device and garbage can

Technical Field

The utility model belongs to the garbage bin field specifically is a dirt gas separator and is equipped with dirt gas separator's garbage bin.

Background

The existing garbage bin or dust collector with dust collection function usually adopts filter structures such as a filter screen and the like, or adopts a cyclone separation device to realize dust-air separation.

Cyclonic separating apparatus has the disadvantage of being bulky and therefore is relatively common in vacuum cleaners and is difficult to use in a trash can.

In the technical scheme of adopting simple filter screen, there is the not enough of very easy adhesion and accumulation dust on the filter screen. In addition, during maintenance operations such as replacement of garbage bags, dust on the filter screen is easily desorbed and is easily diffused to the environment, and at the moment, the dust is easily inhaled by a user, so that the sanitation problem is caused.

SUMMERY OF THE UTILITY MODEL

On the one hand, in order to overcome the easy outdiffusion's of adnexed dust on the current filter screen defect, the utility model provides a dirt gas-separating device, including upside open-ended lower cover for seal the open-ended upper cover of lower cover, filtering component and flange, wherein:

the side wall of the lower cover is provided with an air suction port and a dust outlet;

the lower cover is provided with a dust-air interface for introducing dust air/garbage and is communicated with the dust outlet through a dust channel;

the lower cover is provided with an exhaust interface, the filter assembly is arranged in an inner space between the upper cover and the lower cover and covers the air suction port, and the exhaust interface is communicated with the air suction port through the inner space;

the air suction port is formed by one or more through holes, the blocking edge is blocked outside all the through holes forming the air suction port, and a gap which is opened downwards is arranged between the blocking edge and the air suction port. The dust and dirt on the outside flows first to the gap, and then the air can pass through the filter assembly inside the suction opening, while the dust and dirt are blocked on the outside and settle by gravity.

Although the dust cannot be prevented from being attached to and accumulated at the air suction port, the retaining edge can also play a role in shielding the accumulated dust, and the thrown-in garbage can be prevented from being rubbed with the air suction port, so that the dust at the air suction port is prevented from being lifted, and the dust is more attractive compared with the exposed air suction port. Further, even if the dust is desorbed from the suction port in the case where the rib is impacted, it is apparent that the desorbed dust can be prevented from being diffused into the environment because the gap between the rib and the suction port is opened downward.

The gap between the flange and the air suction port has a certain filtering function, and can prevent larger garbage from moving to the air suction port to cause the blockage or partial blockage of the air suction port. Smaller waste is allowed to pass through the gap to the suction opening.

Detailed Description

The invention is further described with reference to the following figures and specific embodiments.

Referring to fig. 1, the dust-gas separating apparatus of the present embodiment includes a body. The body is mainly composed of an upper cover 10 and a lower cover 20 which are covered together, and is of a detachable structure. In some embodiments, the body may also be provided as a unitary structure.

The middle part of the lower cover 20 is an open space 30 which is open at the upper and lower parts. The lower cover 20 has an air suction port 21 formed on an inner periphery thereof and communicating with the open space 30.

As shown in fig. 2, an exhaust port 22 is further disposed on the lower cover 20, and the exhaust port 22 is communicated to the air inlet 21 through an inner space 31 between the upper cover 10 and the lower cover 20. The inner space 31 is also provided with a filter assembly 40 inside the suction port 21. The filter assembly 40 blocks the air inlet 21 and forms an air-permeable structure to allow air to pass through, thereby preventing dust and dirt from entering the inner space 31.

The exhaust interface 22 is used for communicating with a fan (not shown in the figure), and under the suction action of the fan, an air flow which is exhausted from the exhaust interface 22 into the fan after passing through the air suction port 21 and the internal space 31 from the open space 30 is formed. In the process of forming the aforementioned gas flow: a part of the dust and garbage entering the open space 30 is settled by gravity, and a part of the dust with small particle size (smaller mass) flows to the air suction port 21 and is blocked outside the filtering component 40 at the air suction port 21 to complete the dust-air separation.

Preferably, the filter assembly 40 is filter cotton.

The inner edge of the upper cover 10 is also provided with a flange 11 extending downward at least to the lower edge of the air inlet 21 on the lower cover. It will be readily appreciated that there is a suitable clearance between the rib 11 and the air inlet 21 to prevent the rib 11 from blocking the air inlet 21. The size of the gap between the two is not particularly limited and may be selected as desired.

On the other hand, the rib 11 is blocked outside the air inlet 21, which is more beautiful. On the other hand, the ribs 11 also modify the open space 30 and the airflow field in the vicinity of the open space 30 to promote dust-gas separation and gravity settling of the larger mass of waste as compared to a fully open, non-occluded configuration.

Referring to fig. 3, the suction port 21 is provided on the inner wall of the dust-air separating apparatus without being blocked. The various circles in the figure represent dust and air, and arrows a represent air flow.

Referring to fig. 4, the lower portion of the rib 11 is substantially level in height with the lower portion of the air inlet 21, as compared with the structure shown in fig. 3. The various circles in the figure represent dust and air, and arrows B represent air flow. The rib 11 significantly alters the airflow path as shown by comparison of figures 3 and 4. Under the condition that the retaining edge 11 is arranged, the dust and gas entering the open space 30 firstly form downward diving airflow, and in the process, downward momentum of the garbage with larger mass is increased, so that the garbage is promoted to settle; subsequently, the remaining dust air mainly carrying the smaller-mass dust flows toward the air inlet 21 and starts to rise near the air inlet 21 to enter the gap between the air inlet 21 and the rib 11, at which time the dust and other dust are caught and the air enters the inner space 31.

As shown in fig. 5, the lower portion of the rib 11 may also extend downward such that the lower side edge thereof is located below the suction port 21 in height. Preferably, the lower portion of the rib 11 is 0.5 to 2cm lower than the lower edge of the air inlet 21 in height.

In addition, the rib 11 changes the airflow path, blocks the air inlet 21, and blocks dust adsorbed at the air inlet 21. Dust is not easily accumulated on the visible portion of the upper cover 10.

When the dust-gas separating device is applied to a garbage can, the middle part of the upper cover 10 is also opened up and down to allow garbage to pass through the middle parts of the upper cover 10 and the lower cover 20 from top to fall into a garbage bag below (the dust-gas separating device is arranged above the garbage bag).

At this time, compare fig. 3, 4 again: if the air inlet 21 is not blocked, it is easy for the thrown-in garbage to be scraped through the air inlet 21, and the dust adsorbed at the air inlet 21 is further raised, and the dust is diffused to the environment. When the rib 11 is provided, the garbage throwing action hardly interacts with the air inlet 21. Even when the garbage is thrown toward the rib 11, the dust separated from the air inlet 21 inside the rib 11 by vibration or impact is not easily diffused to the environment, and the use experience is greatly improved. Thus, the ribs 11 provide advantages in terms of promoting settling, preventing dust from spreading, user experience, and appearance.

The dust and gas can be led from a further gas duct into the open space 30 in the middle of the dust and gas separating device. Alternatively, as shown in fig. 1, a dust-air interface 23 for connecting with a dust-air duct (not shown) may be further provided on the lower cover 20. The inner side of the lower cover 20 is also provided with a dust outlet 24 communicated with the open space 30, and the dust-air interface 23 is connected by a dust channel 25 on the lower cover 20. The dust and air enter the dust channel 25 from the dust and air interface 23, and then enter the open space 30 from the dust outlet 24.

Preferably, the dust channel 25 is integrally formed with the lower cover 20 by, for example, an injection molding process.

In other embodiments, the dust channel 25 and the lower cover 20 may be configured to be removably secured together.

Referring to fig. 6 and 7, as a preferred embodiment, the lower cover 20 is mainly composed of a substantially rectangular bottom plate 201 and two side plates 202 extending upward from the inner and outer edges of the bottom plate 201. A groove structure is formed between the bottom plate 201 of the lower cover 20 and the side plates 202 on both sides, and the inner space 31 is formed after being engaged with the upper cover 10.

In another embodiment, the lower cover 20 is formed by a semi-circular bottom plate and two side plates extending upward from the inner and outer edges of the bottom plate. In another embodiment, the lower cover 20 is composed of a bottom plate in the shape of a "C" and two side plates extending upward from the inner and outer edges of the bottom plate. The appearance structure of the lower cover 20 may be further modified, and further description thereof is omitted.

The upper cap 10 is covered with the lower cap 20 to close the opening of the upper side of the lower cap 20. Wherein, the upper cover 10 contacts with the side plates 202 of the inner and outer sides of the lower cover 20 to achieve a certain degree of air-lock effect. Preferably, the upper cover 10 and the side plate 202 on both sides of the lower cover 20 are sealed in a contact manner. It is easily understood that the present invention is not limited to the extent that the upper cover 10 and the side plates 202 of the two sides of the lower cover 20 must be completely sealed, and the external structure of the upper cover 10 is not limited in particular, and may be designed as required.

The upper cover 10 is mainly composed of a substantially rectangular top plate 101 and two side plates 102 formed by extending upward the inner edge and the outer edge of the top plate 101. In some embodiments, the side plate 102 on the outside of the upper cover 10 is optional and may be omitted.

A side plate 102 inside the upper cover 10 may serve as the rib 11.

When the side plate 102 on the inner side of the upper cover 10 is blocked outside the dust outlet 24 on the lower cover 20, the side plate 102 is adaptively provided with a through hole 103 on the outer side of the dust outlet 24 on the lower cover 20 to communicate the dust outlet 24 with the open space 30 in the middle of the dust-air separating device.

In some embodiments, the rib 11 of the upper cover 10 has a smaller circumferential length, and the through hole 103 can be omitted when the rib is not blocked outside the dust outlet 24.

Preferably, in the present embodiment, the main structures of the upper and

lower covers

10 and 20 are substantially the same to obtain a compact assembly structure. The upper cover 10 is sleeved on the lower cover 20, and the two side plates 102 inside and outside the upper cover 10 are enclosed outside the two side plates 202 of the lower cover 20.

The dust-gas separating device can be arranged in the garbage can. Like a common trash can, the trash can comprises a can body and a can cover. The barrel cover can be formed by a large cover or a large cover and a small cover arranged on the large cover according to requirements. The dust-gas separating device is fixed in the big cover.

When the garbage is thrown into the garbage container, the small cover is opened. And when the garbage bag is replaced and other maintenance operations are carried out, the large cover is opened.

The embodiments of the present invention are only used for illustration, and do not limit the scope of the claims, and other substantially equivalent alternatives that may be conceived by those skilled in the art are within the scope of the present invention.
