However, due to the defects of product design, the condition in the dust collecting barrel is usually known only after the dust collecting barrel is disassembled, the operation is inconvenient, the user experience is influenced, and the product is easily damaged by frequent disassembling and assembling operations.

Dust collecting device 1 in this embodiment, through set up the observation window 112 that is suitable for observing the inside condition of dust absorption passageway 111 on box 11, the user can observe the state in dust absorption passageway 111 through observation window 112 directly perceivedly, can in time discover blocking phenomenon and jam position to carry out corresponding clearance operation, need not frequently to carry out dismouting operation, convenient to use is favorable to improving user and uses experience.

It should be noted that, one or more observation windows 112 may be provided in the present embodiment, and the observation windows 112 may be respectively disposed at different positions of the dust suction passage 111. In addition, the observation window 112 may include only a window structure, or may include a shielding structure adapted to the window structure, and the shielding structure has a certain light transmittance and is suitable for human eye observation, for example, the shielding structure is made of a transparent material such as glass, plastic, resin, etc.

In the using process, the user can observe the inside of the dust collection channel 111 by observing the bottom case 1131 to know the dust collection state in the dust collection channel 111, and when the dust collection device 1 generates the phenomena of unsmooth dust collection and the like, the user can timely know whether the dust collection channel 111 is blocked through the first observation window 1121, so that the use convenience is greatly improved. In addition, when the user observes the phenomenon of blocking up or dust accumulation in the dust absorption channel 111 through the first observation window 1121, the observation bottom case 1131 can be detached so as to perform corresponding cleaning operation on the dust absorption channel 111, the connection relationship of the observation bottom case 1131 is simpler, the dust collecting device 1 does not need to be detached integrally, and the operation is more convenient.

As shown in Figs. 3 and 4, the dust collecting chamber 12 is positioned in the tub 114 above the base 113, and the suction inlet 1111 of the suction passage 111 is positioned on a side wall of the tub 114 so as to be connected to a matched suction device in use. The top cover 115 is sealingly connected to the side walls of the dust collecting chamber 12, and the top cover 115 forms a top wall of the dust collecting chamber 12 to prevent dust-laden air from leaking outwardly from the edges of the top cover 115.

The dust collecting chamber 12, the barrel 114 and the base 113 can be connected and positioned by a plug-in structure and a snap-in structure.

Further, in some embodiments of the present invention, as shown in fig. 3 to 5, the dust suction passage 111 specifically includes a first passage 1113 and a second passage 1114. The first passageway 1113 is disposed within the base 113 and the second passageway 1114 is disposed within the barrel 114. The outer port of the first passage 1113 forms a dust suction inlet 1111, and the other end of the first passage 1113 away from the dust suction inlet 1111 is connected with the second passage 1114; viewing the bottom shell 1131 forms a bottom wall of the first channel 1113. The second channel 1114 extends along the height direction, a sealing pipeline 1115 is arranged in the second channel 1114, the bottom end of the sealing pipeline 1115 is connected with the first channel 1113 in a sealing way, and the top of the sealing pipeline 1115 is connected with the dust collecting cavity 12. Specifically, as shown in fig. 4, the top of the sealing tube 1115 extends to the side of the dust collecting cavity 12, and the top of the sealing tube 1115 is provided with an elbow joint 1116 extending to the side close to the dust collecting cavity 12, and a section of the elbow joint 1116 close to the dust collecting cavity 12 forms a dust suction outlet 1112; correspondingly, the side wall of the dust collecting cavity 12 is provided with a dust collecting opening 122, and the dust collecting opening 122 is hermetically connected with the dust suction outlet 1112.

It should be noted that, in use, the inlet of the air-permeable dust collecting bag 121 may be provided with a pre-formed sealing structure (e.g. a sealing gasket) and connected to the dust collecting opening 122 of the dust collecting cavity 12 by means of a snap-fit connection, as shown in fig. 3, so as to form a sealing connection with the dust suction outlet 1112 and fix the air-permeable dust collecting bag 121. The air-permeable dust collecting bag 121 may be made of disposable material, such as air-permeable dust-isolating filter cloth, or may be made of recyclable material. The shape of the air-permeable dust collecting bag 121 is adapted to the inner dimension of the dust collecting cavity 12, for example, it is a rectangular parallelepiped structure matched with the dust collecting cavity 12.

Further, in one embodiment, as shown in fig. 4 and 5, a dust suction inlet 1111 is formed on the base 113 at a position near the middle of the front end of the base 113 so as to be connected to the dust collecting device 1. The first passage 1113 extends from the position of the dust suction inlet 1111 to the left or right side of the base 113 as a whole, so that the second passage 1114 is located in the tub 114 as a whole near the left or right side plate, which is advantageous for optimizing the spatial arrangement. The shapes of the first observation window 1121 and the observation bottom case 1131 are also adapted to the overall extending direction of the first channel 1113, that is, one end of the observation bottom case 1131 close to the dust suction inlet 1111 is located at a position close to the middle of the front end of the base 113, and one end of the observation bottom case 1131 close to the second channel 1114 extends to the left end or the right end of the base 113, so as to increase the observation area and enlarge the observation field of view, and the internal condition of the first channel 1113 can be displayed to the greatest extent through the first observation window 1121 and the observation bottom case 1131.

In another specific implementation, as shown in fig. 1, 5 and 6, the height of the end of the bottom case 1131 near the second channel 1114 is observed to be greater than the height of the end of the bottom case 1131 near the dust suction inlet 1111, that is, the height of the end of the bottom case 1131 near the second channel 1114 is observed to be close to the end of the dust suction inlet 1111. After entering the first passage 1113 through the dust suction inlet 1111, the airflow gradually ascends while flowing toward the second passage 1114, so that the airflow can flow more smoothly at the connection between the first passage 1113 and the second passage 1114. It can be understood that, because the second channel 1114 extends along the height direction, the junction of the second channel 1114 and the first channel 1113 forms a turn, if the turning angle is too large, the direction of the airflow passing through the turn is suddenly changed, so that the sidewall of the dust suction channel 111 is easily impacted greatly, the stress on the sidewall of the turn is concentrated, and the sidewall is easily cracked or damaged. Through the above-mentioned improvement to observing drain pan 1131, can reduce the turn angle of the junction of first passageway 1113 and second passageway 1114, make the air current can change the direction comparatively gently and flow into the sealed pipeline 1115 in second passageway 1114, be favorable to improving the atress distribution condition, increase of service life.

As shown in fig. 7 and 8, a plurality of ear structures 1132 may be disposed at a side edge of the bottom case 1131, and the ear structures 1132 have connection holes formed thereon to form a bolt connection with the base 113 through the ear structures 1132, so as to facilitate the disassembling and assembling operation. Of course, it is not limited to the bolt connection between the bottom case 1131 and the base 113, and other connection methods may be adopted, for example, a snap structure is adopted for clamping.

In some embodiments of the present invention, as shown in fig. 1, 3 and 9, the observation window 112 of the dust collecting device 1 further includes a second observation window 1122. A second viewing window 1122 is provided on the sidewall of the canister 114 opposite the sealed conduit 1115. The sealing duct 1115 is transparent, and the second observation window 1122 can expose at least a portion of the sealing duct 1115, so that a user can observe the inside of the sealing duct 1115 through the second observation window 1122 to know whether dust is accumulated or blocked in the sealing duct 1115.

In this embodiment, a first observation window 1121 and a second observation window 1122 are provided, which correspond to the first channel 1113 and the second channel 1114 of the dust suction channel 111, respectively, so that a user can observe the sealed pipes 1115 of the first channel 1113 and the second channel 1114 as required, thereby further expanding the observation range and reducing the observation dead zone.

Further, in some embodiments, as shown in fig. 1, 9 and 10, a viewing frame 1141 is disposed at an edge of the first viewing window 1121, and a viewing port 1143 is disposed on the viewing frame 1141. The viewing frame 1141 is adapted to the sealing tube 1115 at a side facing the sealing tube 1115 (i.e., a side facing the inside of the barrel 114), and an edge of the viewing port 1143 abuts against the sealing tube 1115, so as to reduce a distance between the viewing port 1143 and the sealing tube 1115, which is beneficial to expanding a viewing field of the viewing port 1143. One side of the observation frame 1141 facing away from the sealed pipe 1115 (i.e., the side facing the outside of the barrel 114) is provided with a bevel edge structure 1142, the bevel edge structure 1142 is located between the outer edge of the observation frame 1141 and the observation port 1143, and the bevel edge structure 1142 gradually recesses inwards from the outer edge of the observation frame 1141 to the observation port 1143, so that one side of the observation frame 1141 facing away from the sealed pipe 1115 forms a structure similar to a horn shape, so as to further enlarge the field of view of the observation port 1143, and a user can observe the inside of the sealed pipe 1115 at a position having a certain inclination angle with the observation port 1143.

It can be understood that the observation frame 1141 has a certain thickness, the side wall of the observation frame 1141 can block a part of the observation field of view of the observation port 1143 under normal conditions, especially when the position of the user is at a certain inclination angle with the observation port 1143 (for example, when observing from the oblique upper side or the left and right sides of the first observation window 1121), the field of view is small, the user needs to move the dust collecting barrel to the position where the two eyes are close to the observation port 1143, or bend over and squat to make the two eyes be close to the observation port 1143, so that the user can observe the dust collecting barrel well, and the use is inconvenient. The field of view of viewing aperture 1143 can be further enlarged by setting up the above-mentioned hypotenuse structure 1142, so that convenience of observation operation is further improved, and user experience is improved.

Specifically, as shown in fig. 11, 12 and 13, the edge of the view port 1143 may be configured to have a structure in which the left and right sides thereof are slightly bent toward the inside of the barrel 114 and the upper and lower ends thereof are slightly bent toward the outside of the barrel 114, and the joints are smoothly curved, so as to increase the contact area between the sealed pipe 1115 and the view port 1143, so that the side wall of the sealed pipe 1115 can be stably in low contact with the edge of the view port 1143, and at least a part of the side wall of the sealed pipe 1115 extends outward from the view port 1143. In addition, the beveled edge structure 1142 may cover one circumference of the viewing port 1143 in the circumferential direction, which, as in the example of fig. 1 and 10, may enlarge the field of view of the viewing port 1143 over a range of 360 °; of course, the beveled edge structure 1142 may cover a partial range of the viewing port 1143 in the circumferential direction, and the beveled edge structure 1142 may not be provided for an angular position that is not frequently observed by the user, for example, the beveled edge structure 1142 may cover only the upper side and the left and right sides of the viewing port 1143.

Further, as shown in fig. 9 and 10, the upper end and the lower end of the observation frame 1141 are both circular arc-shaped structures. The arc structure at the upper end of the observation frame 1141 protrudes upward, and the arc structure at the lower end of the observation frame 1141 protrudes downward, so that the observation frame 1141 forms an annular structure similar to an ellipse, and the observation port 1143 is matched with the observation frame 1141 in shape, that is, the observation port 1143 also forms an arc structure with an upward protruding upper end and an arc structure with a downward protruding lower end, so as to increase the size of the observation port 1143 in the height direction, so as to be matched with the sealed pipe 1115 extending in the height direction, and further enlarge the observation field of view in the height direction. In addition, the circular arc structure also enables the edge of the viewing port 1143 to better abut the side wall of the sealing tube 1115.

It should be noted that the arc of the arc-shaped structure may be set according to specific use requirements, and preferably, the arc-shaped structure may be set to be a semicircular structure (for example, the arc-shaped structure located at the upper end of the observation frame 1141 in fig. 10), and of course, the arc-shaped structure may also be a minor arc or a major arc.

In addition, as shown in fig. 11 to 13, a snap structure 151 may be further disposed on the outer side wall of the observation frame 1141 to connect with the barrel 114 through the snap structure 151, and at the same time, to facilitate the disassembling and assembling operation.

In some embodiments of the present invention, as shown in fig. 1 to 4, in the dust collecting apparatus 1, the top cover 115 of the housing 11 is rotatably connected to the tub 114, and the tub 114 and the dust collecting chamber 12 can be opened or closed by the turning operation of the top cover 115 with respect to the tub 114. The top of the sidewall of the dust collecting cavity 12 is provided with a wide edge structure 123, the top of the top cover 115 is correspondingly provided with a sealing gasket 1151, and when the top cover 115 is in a closed state, the sealing gasket 1151 abuts against the wide edge structure 123, so that the space between the top cover 115 and the dust collecting cavity 12 is sealed by utilizing the extrusion between the wide edge structure 123 and the sealing gasket 1151. When the suction fan 13 works, the top cover 115 presses the wide-side structure 123 on the dust-collecting cavity under the action of the external atmospheric pressure to form a vacuum negative pressure in the dust-collecting cavity 12, and then the sealed pipe 1115 and the dust-collecting channel 111 generate a suction force at the dust-collecting inlet 1111, so that particles such as dust in the dust-collecting device abutting against the dust-collecting inlet 1111 are sucked into the air-permeable dust-collecting bag 121 in the dust-collecting cavity 12. Specifically, the wide-side structure 123 may further include a clamping structure capable of being engaged with the top cover 115 to clamp the top cover 115.

In some embodiments of the present invention, as shown in fig. 3 and 4, an air exhaust cavity 14 is disposed below the dust collecting cavity 12 in the barrel body 114, and the air exhaust fan 13 is disposed in the air exhaust cavity 14; the bottom wall of the dust collecting cavity 12 is provided with an air suction opening 124, and the dust collecting cavity 12 is communicated with the air suction cavity 14 through the air suction opening 124; an air outlet 141 is arranged on the side wall of the air draft cavity 14. When the suction fan 13 works, a negative pressure is formed in the dust collecting cavity 12, so that the airflow in the dust collecting cavity 12 is sucked into the air suction cavity 14 through the air suction opening 124 and is discharged outwards through the air outlet 141. Wherein, the suction opening 124 is provided with a filtering structure to filter particles such as dust entrained in the air flow. The air flow enters the air-extracting cavity 14 after being filtered and then is discharged through the air outlet 141, so that the discharge of pollutants can be effectively reduced, and the pollution to the outside air is prevented.
