Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cleaning device, specifically provides a dust collector and cleaning device. BACKGROUND

[0002] As a common cleaning tool, the dust collector is widely used in the cleaning work of family, commercial place and other environment. The existing dust collector usually comprises a main body, a dust suction fan and a filter and other components. Among them, the main body is defined with a dust suction channel, a dust gas separation chamber and an exhaust port which are communicated in sequence, and a dust collection chamber which is communicated with the dust gas separation chamber. When the dust suction fan rotates, the dust-containing airflow enters the dust gas separation chamber through the dust suction channel, the airflow is filtered by the filter and then discharged through the exhaust port, and the separated dust and other foreign matters fall into the dust collection chamber.

[0003] Among them, the filter generally has a tubular filter screen located in the dust gas separation chamber, and the end of the filter screen close to the dust collection chamber is provided with a stop ring. The stop ring is located on the outer side of the radial direction of the filter screen, and there is an annular channel between the outer side of the radial direction of the stop ring and the dust gas separation chamber, so as to ensure that the foreign matters in the dust gas separation chamber can fall into the dust collection chamber through the annular channel, and at the same time, the foreign matters in the dust collection chamber can be prevented from entering the dust gas separation chamber.

[0004] However, due to the existence of the stop ring, some foreign matters (such as hair wound on the filter) in the dust gas separation chamber are not easy to enter the dust collection chamber. When the user cleans the foreign matters in the dust collector, the user needs to manually clean the dust gas separation chamber, and even needs to disassemble the filter, which not only easily dirties the user's hands, but also is extremely inconvenient to operate, and the user's use experience is poor.

[0043] As Figure 1 And Figure 2 Indicated, in some embodiments of the utility model, dust collector 100 includes main body 110, dust suction fan 120, filter 130 and partition 141.

[0044] Wherein, main body 110 is defined with dust suction passage 111, dust-gas separation chamber 112 and exhaust port 113 communicated in sequence, main body 110 is also defined with dust collection chamber 114 communicated with dust-gas separation chamber 112 and located at the bottom side of dust-gas separation chamber 112.

[0045] Wherein, dust suction fan 120 is installed in main body 110 and is used to drive airflow to flow through dust suction passage 111, dust-gas separation chamber 112 and exhaust port 113 (as Figure 2 Indicated by the dotted line with arrow in the middle) in sequence.

[0046] Wherein, filter 130 is installed in main body 110 and is used to filter the airflow from dust-gas separation chamber 112 to exhaust port 113.

[0047] Wherein, partition 141 is arranged between dust-gas separation chamber 112 and dust collection chamber 114, and is movably connected with main body 110, so that partition 141 can be moved to the position of half-shielding dust-gas separation chamber 112 to block the foreign matter 300 (such as dust, paper scraps, fruit shells, food residues and other garbage) in dust collection chamber 114 from entering dust-gas separation chamber 112, and partition 141 can be moved to the position of opening dust-gas separation chamber 112 to prevent partition 141 from hindering foreign matter 300 in dust-gas separation chamber 112 from entering dust collection chamber 114.

[0048] The dust separating cavity 112 is connected with the dust collecting cavity 114, and the dust separating cavity 112 is connected with the dust collecting cavity 114 through the dust separating cavity 112 and the dust collecting cavity 114.

[0049] As shown in Figure 2 In some embodiments of the utility model, the main body 110 can further be defined with an exhaust cavity 115, which is arranged between the exhaust port 113 and the dust separating cavity 112. In other words, the exhaust cavity 115 is in communication with the dust separating cavity 112, and the exhaust port 113 is arranged on the peripheral wall of the exhaust cavity 115.

[0050] Continuing to refer to Figure 2 In some embodiments of the utility model, the dust collecting fan 120 is installed into the exhaust cavity 115. Moreover, the dust collecting fan 120 can be a centrifugal fan, an axial fan or an inclined flow fan.

[0051] As shown in Figure 2 In some embodiments of the utility model, the peripheral wall of the dust separating cavity 112 extends to the dust collecting cavity 114 along the direction close to the dust collecting cavity 114, so that the foreign matter 300 in the dust collecting cavity 114 can enter the dust collecting cavity 114 along the peripheral wall of the dust separating cavity 112.

[0052] Further, although not shown in the drawings, in some embodiments of the utility model, the dust separating cavity 112 can be configured as a cyclone separating cavity.

[0053] Exemplarily, the central extension line of the dust suction passage 111, which is in communication with the air outlet of the dust separating cavity 112, does not intersect with the central axis of the dust separating cavity 112, and is arranged at intervals.

[0054] As shown in Figure 2 In some embodiments of the utility model, the filter 130 comprises a conical filter screen 131 located in the dust separating cavity 112, and the small end of the conical filter screen 131 is located on the side close to the dust collecting cavity 114 of the large end section.

[0055] As can be understood by those skilled in the art, the conical filter screen 131 can better cooperate with the cyclone separation chamber, so as to avoid the heavy foreign matter 300 from climbing upward along the peripheral wall of the conical filter screen 131. In other words, the conical filter screen 131 is more conducive to making the heavy foreign matter 300 fall into the dust collecting chamber 114.

[0056] In addition, in other embodiments of the present application, the conical filter screen 131 can be set to other any feasible forms according to the needs of those skilled in the art, such as a circular tube-shaped filter screen, a sheet-shaped filter screen, etc.

[0057] As shown in Figure 2 In some embodiments of the present application, when the partition plate 141 is in the position of half-shielding the dust-gas separation chamber 112, a communication passage 101 is formed between the dust-gas separation chamber 112 and the dust collecting chamber 114, so as to make the foreign matter 300 in the dust-gas separation chamber 112 enter the dust collecting chamber 114 through the communication passage 101. The communication passage 101 can be in the shape of a crescent, a C or a ring.

[0058] Further, although not shown in the drawings, in some embodiments of the present application, a stop structure is arranged in the main body 110. When the partition plate 141 is in the position of half-shielding the dust-gas separation chamber 112, the stop structure abuts against the partition plate 141, so as to ensure that the communication passage 101 is formed between the dust-gas separation chamber 112 and the dust collecting chamber 114, and prevent the partition plate 141 from shaking.

[0059] The stop structure can be a convex rib protruding inward from the peripheral wall of the dust collecting chamber 114, or a convex rib or columnar structure protruding from the bottom surface of the peripheral wall of the dust-gas separation chamber 112 to the dust collecting chamber 114. Of course, the stop structure can be set to other any feasible structure according to the needs of those skilled in the art.

[0060] Further, in some embodiments of the present application, the partition plate 141 can be arranged to move to the position of half-shielding the dust-gas separation chamber 112 or opening the dust-gas separation chamber 112 in a flipped manner.

[0061] As shown in Figure 2 In some embodiments of the present application, the dust collector 100 can further include a flexible member 142 connecting the partition plate 141 and the main body 110 together, so as to make the partition plate 141 swing up and down through the flexible member 142.

[0062] The flexible member 142 can be any feasible member, such as a flexible plate, a flexible cloth, a hinge, etc.

[0063] In addition, in other embodiments of the present application, the skilled in the art can replace the flexible member 142 with any other feasible member or structure according to the need, for example, replace the flexible member 142 with a connecting rod or a hinge.

[0064] As shown in the drawings, Figure 2 In some embodiments of the present application, the bottom surface of the peripheral wall of the dust-gas separation chamber 112 is inclined towards the dust collection chamber 114 along the direction close to the flexible member 142, so that the baffle 141 is kept in the position of half-shielding the dust-gas separation chamber 112.

[0065] Of course, in other embodiments of the present application, the skilled in the art can set the bottom surface of the peripheral wall of the dust-gas separation chamber 112 as a plane, or inclined towards the dust collection chamber 114 along the direction away from the flexible member 142 according to the need.

[0066] Further, in some embodiments of the present application, the baffle 141 is configured to move to and keep in the position of half-shielding the dust-gas separation chamber 112 when the air pressure in the dust-gas separation chamber 112 is less than the air pressure in the dust collection chamber 114. The baffle 141 is configured to move to and keep in the position of opening the dust-gas separation chamber 112 when the air pressure in the dust-gas separation chamber 112 is greater than or equal to the air pressure in the dust collection chamber 114.

[0067] In order to achieve the above-mentioned purpose, the baffle 141 can adopt a plate-shaped structure made of light materials such as plastic, carbon fiber, rubber, etc.

[0068] Alternatively, the skilled in the art can set the flexible member 142 as a plastic sheet or a metal sheet with a certain elasticity according to the need, so that the baffle 141 is moved to and kept in the position of half-shielding the dust-gas separation chamber 112 under the action of the elasticity thereof.

[0069] As shown in the drawings, Figure 2 In some embodiments of the present application, the dust collector 100 can further include a dust collection cover 151 and a release button 152. The dust collection cover 151 is rotatably connected with the main body 110 to open and close the dust collection chamber 114. The release button 152 is installed on the main body 110, and is used to lock the dust collection cover 151 to the position of closing the dust collection chamber 114. The release button 152 releases the dust collection cover 151 when pressed, opening the dust collection chamber 114.

[0070] Further, although not shown in the drawings, the dust collector 100 of the present application can further include a suction head in communication with the dust suction channel 111, and can further include a connecting pipe arranged between the suction head and the dust suction channel 111.

[0071] It should be noted that since other components of the dust collector 100 are not directly related to the technical problems and main technical concepts to be solved by the utility model, and are well known to those skilled in the art, the utility model will not be described in detail.

[0072] The working principle of the dust collector 100 of the utility model will be briefly described below. Figure 2

[0073] When the dust collector 100 works, the dust suction fan 120 rotates. Under the action of the dust suction fan 120, a negative pressure is generated in the dust-gas separation chamber 112, so that the air pressure in the dust-gas separation chamber 112 is less than the air pressure in the dust collection chamber 114, so that the partition plate 141 moves to and remains at a position for partially shielding the dust-gas separation chamber 112. And under the action of the negative pressure, the airflow (as shown by the dotted line with an arrow in Figure 2 ) carrying the foreign matter 300 enters the dust-gas separation chamber 112 through the dust suction passage 111, and the airflow is filtered by the filter 130 and then discharged through the air outlet 113, and the separated foreign matter 300 such as dust falls into the dust collection chamber 114 (as shown by the solid line with an arrow in Figure 2 ).

[0074] When the dust collector 100 stops working, the air pressure in the dust-gas separation chamber 112 is equal to the air pressure in the dust collection chamber 114, so that the partition plate 141 can move to and remain at a position for opening the dust-gas separation chamber 112 under the action of its own gravity. At this time, the foreign matter 300 in the dust-gas separation chamber 112 is no longer blocked by the partition plate 141 and falls into the dust collection chamber 114.

[0075] As shown in Figure 3 and Figure 4 , in order to automatically clean the dust in the dust collector 100, the utility model further provides a base station 200, which is adapted to the dust collector 100 and is used for sucking out the foreign matter 300 in the dust collection chamber 114 of the dust collector 100.

[0076] In some embodiments of the utility model, the dust collector 100 and the base station 200 jointly constitute a cleaning device 001, in other words, the cleaning device 001 comprises the dust collector 100 and the base station 200.

[0077] As shown in Figure 4 , in some embodiments of the utility model, the base station 200 comprises a station body 210 and a dust collection fan 220.

[0078] The station body 210 is provided with a dust collection port 211 and a dust collection chamber 212 in communication with the dust collection port 211, and the dust collection port 211 is adapted to the dust collection chamber 114, so that the foreign matter 300 in the dust collection chamber 114 enters the dust collection chamber 212.

[0079] ​The dust collection fan 220 is used to drive air to flow through the dust-gas separation chamber 112, the dust collection chamber 114 and the dust collection chamber 212 in sequence, so as to collect the foreign matter 300 in the dust collection chamber 212. When the dust collection fan 220 rotates, a negative pressure is formed in the dust collection chamber 114, and the air pressure in the dust-gas separation chamber 112 is greater than that in the dust collection chamber 114, so that the partition plate 141 is forced to move to and remain at a position of opening the dust-gas separation chamber 112. It is ensured that the partition plate 141 is opened.

[0080] The cooperation method and working principle of the dust collector 100 and the base station 200 will be described below with reference to the accompanying drawings. Figure 2

[0081] When it is needed to pour out the foreign matter 300 in the dust collection chamber 114, the dust collector 100 is inserted into the dust collection port 211 of the base station 200 to fix the dust collector 100 to the base station 200 and align the dust collection chamber 114 with the dust collection port 211. In this process, the release button 152 is triggered by the base station 200 to release the dust collection cover 151, so that the foreign matter 300 in the dust collection chamber 114 falls into the dust collection chamber 212.

[0082] Then, the dust collection fan 220 is started to drive air to flow along the path shown by the dotted line with arrows, and thus the partition plate 141 is kept at the position of opening the dust-gas separation chamber 112, so that the residual foreign matter 300 in the dust collection chamber 114 and the dust-gas separation chamber 112 is sucked into the dust collection chamber 212. Figure 2

[0083] Based on the foregoing description, it can be understood by those skilled in the art that the dust collector 100 of the present application can clean the foreign matter 300 in the dust-gas separation chamber 112 more thoroughly, reduce manual cleaning operation and improve user experience.

[0084] So far, the technical scheme of the present application has been described in combination with the foregoing embodiments, but those skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments. Without deviating from the technical principles of the present application, those skilled in the art can disassemble and combine the technical schemes in the above-mentioned embodiments, or make equivalent changes or replacements to related technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.

[0085] ​​Finally, it needs to be explained that in the present utility model, the term "communication" means fluid communication to allow fluid (for example, air, liquid) to flow between two things in communication with each other. And the "communication" can be fluid leakage-free flow between two things in communication with each other, or can be fluid leakage flow between two things in communication with each other.
