Self-propelled cleaning device dust box construction

The present invention relates to a dust box construction, and more particularly to a self-propelled cleaning device dust box construction for self-propelled cleaning devices that operate with autonomous displacement.

Press, the general self-propelled cleaning device, also known as the cleaning robot, is small in size and can automatically walk around to carry out the work of cleaning the floor dust. In order to collect the dust collected by the self-propelled cleaning device, it is usually self-propelled. A dust collecting box is disposed in the body of the cleaning device, and the dust box is generally provided with a chamber, and a dust suction port and a filter member are disposed from the chamber, so that a negative pressure mechanism is disposed outside the filter member. The filter is used to guide the negative pressure to suck dust from the dust suction port, and the dust is left in the chamber between the dust suction port and the filter member. When the dust box chamber is full of dust, a message usually appears, and the user must set the dust. After the dust inside the dust box is removed, put it into the self-propelled cleaning device to continue the cleaning task.

The self-propelled cleaning device of the prior art is often free to collect the dust collecting box due to its freely operable function, and the user often finds it difficult to know immediately; and because of its small size, the dust collecting box is usually also The volume is small and the dust is very fast. However, when the dust chamber is full of dust, the dust will adhere to the surface of the filter at the same time, so that the fine vent hole of the filter is blocked, which seriously affects the vacuum of the negative pressure mechanism. Airflow, on the other hand, in order to solve this problem, the user must simultaneously clean the filter when dusting the dust inside the dust box, causing a lot of trouble! However, even if the filter is cleaned, under repeated use, even if the cleaning is still more serious, the filter must be replaced after a certain period of time, which is an inevitable demand. The surface will cause an increase in the cost of use. On the other hand, the pipeline for purchasing the filter element of the model is limited, and the replacement of the filter member may become a nightmare for the user!

Therefore, the object of the present invention is to provide a self-propelled cleaning device dust box structure which can reduce the clogging of the filter member.

The structure of the dust box of the self-propelled cleaning device according to the present invention comprises: a box body having a receiving space for accommodating dust therein, the accommodating space forming a bottom surface and four sides erected on the side of the bottom surface, The accommodating space is provided with a dust inlet and a vacuum suction port; a cover body is disposed above the accommodating space of the box body; a filter member is disposed at the negative pressure suction port of the accommodating space of the box body, and A first filter material is disposed thereon; a second filter material is a disposable filter material having a venting hole, and the filter material is coated to protect the first filter material from dust contamination.

The self-propelled cleaning device dust collecting box structure of the present invention, the second filter material is covered by the filter element, and is sealed at the vacuum suction port, and is between the dust inlet and the passage of the negative pressure airflow, so the dust inlet is The dust entering the space will be placed in the accommodating space, and will be adsorbed on the side of the second filter material toward the accommodating space. After a certain amount of accumulation, the user can open the cover body without the need for opening the cover portion. The filter element is removed, and the second filter material is taken out together, and the second filter material is discarded. Since the second filter material is a disposable filter material such as toilet paper, the cost is low and easy to obtain; After the second filter material, the filter member can be kept clean because it is covered by the second filter material. Therefore, after the new second filter material is continuously coated, the vacuum suction capability of the negative pressure airflow can be obtained.

The first figure is a perspective view of the novel embodiment.

The second figure is a schematic exploded view of the second filter material of the present invention, which is assembled with the filter body and assembled with the casing.

Please refer to the dust box of the new embodiment as shown in the first and second figures. The housing 1 has a accommodating space 11 for accommodating dust. The accommodating space 11 defines a bottom surface 12 and four side surfaces 13 standing on the periphery of the bottom surface 12. The accommodating space 11 is provided with a dust inlet 14 . And a negative pressure suction port 15 respectively located on two opposite sides; the dust inlet 14 is provided with a thin type of check piece 142 which is sleeved on a pivot pin 141 at both ends, and the negative pressure suction port 15 is externally facing Forming a recessed square groove, forming a wide flange 151 on the inner periphery of the recessed square groove, and providing a rib 152 on the inner side of the accommodating space 11; the negative pressure suction port 15 is concave A cover portion 153 is defined in the upper edge of the square groove; a cover body 2 is disposed above the accommodating space 11 of the casing 1, and the cover body is provided with a handle 21; a filter member 3 is provided. The filter member 3 includes a frame 31 having an outer peripheral edge conforming to the shape of the recessed square groove of the negative pressure suction opening 15 at the negative pressure suction opening 15 of the accommodating space 11 of the casing 1. A plurality of creased first filter members 32 are formed in the frame 31, and a plucking portion 33 is protruded from the frame 31; the outer periphery of the frame 31 is provided with a flexible gasket 3 surrounding the frame 31. 4; a second filter material 4, which is a disposable flaky filter material having a venting opening, such as a toilet paper; the filter element is covered from the accommodating space 11 of the casing 1 toward the accommodating space 11 3, a portion of the second filter medium 4 extends between the periphery of the frame 31 of the filter member 3 and the inner edge of the abutment 151 of the vacuum suction port 15, so that the second filter medium 4 is thereby caulked by the frame 31 of the filter member 3. At the inner edge of the vacuum suction port 15, and by the flexible gasket 34, the sealing seal is pressed against the flange 151 to prevent the first filter material from being contaminated by dust.

In the dust box structure of the self-propelled cleaning device of the present invention, the second filter material 4 is covered by the filter member 3, and is sealed at the vacuum suction port 15 and is interposed between the dust inlet 14 and the negative pressure airflow. Therefore, the dust entering from the dust inlet 14 is placed in the accommodating space 11 and will be adsorbed on the side of the second filter medium 4 toward the accommodating space 11, after a certain cumulative amount, the user can The filter member 3 can be removed from the dial portion 33 without opening the cover body 2, and can be taken out together with the second filter medium 4, The second filter medium 4 is discarded, and the second filter medium 4 is a disposable filter material such as toilet paper, so that the cost is low and easy to obtain. Further, after the second filter material 4 is taken, the filter element 3 is removed by the second filter medium. The 4 covers can still be kept clean, so after the new second filter 4 is applied, the negative pressure airflow can be obtained.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel specification content, All remain within the scope of this new patent.
