[0061] The embodiments of the present application disclose a dust collecting device and a base station.

[0062] Please refer to Figure 1 and Figure 2 An embodiment of a dust collecting device provided in the embodiments of the present application:

[0063] The dust collecting device 200 is connected with the sound attenuation box 100. The sound attenuation box 100 is provided with a sound attenuation cavity 101, and the sound attenuation box 100 is further provided with an air inlet structure 102 and an air outlet structure 103 which are in communication with the sound attenuation cavity 101; the sound attenuation cavity 101 is filled with a porous noise reduction material 4 between the air inlet structure 102 and the air outlet structure 103; the porous noise reduction material 4 has a porous gap for air flow; the air outlet 522 of the fan 5 of the dust collecting device 200 is connected and communicated with the air inlet structure 102.

[0064] From the above technical solution, it can be seen that the air outlet 522 of the fan 5 of the dust collecting device 200 is connected with the sound attenuation box 100 to construct a new type of dust collecting device 200. The sound attenuation box 100 has a sound attenuation cavity 101 filled with a porous noise reduction material 4, the air flow from the air outlet 522 of the fan 5 enters the sound attenuation cavity 101 through the air inlet structure 102, and the air flow entering the sound attenuation cavity 101 is reflected, superimposed and collided when flowing through the porous noise reduction material 4 to reduce noise, and finally completes the exhaust through the air outlet structure 103. By connecting the dust collecting device 200 with a sound attenuation box 100, the air flow from the fan 5 of the dust collecting device 200 is subjected to sound attenuation treatment, thereby solving the problem of large noise caused by direct exhaust of the dust collecting device 200 in the prior art.

[0065] The above is an embodiment of a dust collecting device 200 provided by the embodiments of the present application, and the following is an embodiment two of a dust collecting device 200 provided by the embodiments of the present application, please refer to Figures 1 to 3 .

[0066] Based on the technical solution of the above embodiment one:

[0067] Further, as for the structure of the dust collecting device 200, it can be as Figure 1 and Figure 3As shown, including dust collecting box 6, dust bag 7, recycling channel 8 and fan 5. Among them, the dust bag 7 is installed in the dust collecting box 6, used for storing the garbage collected from the dust box 303, and the specific structure and installation method of the dust bag 7 can refer to the related dust collecting device in the prior art, and will not be described here. The recycling channel 8 is installed on the dust collecting box 6, and one end is connected and communicated with the dust bag 7 through the dust collecting box 6. Specifically, the recycling channel 8 is used to transport the garbage in the dust box 303, one end of which is connected and fixed on the outer side wall of the dust collecting box 6 and connected and communicated with the dust bag 7. In order to improve the sealing and shock resistance of the one end of the recycling channel 8 connected with the dust collecting box 6, a first soft rubber ring 81 can be provided on the one end of the recycling channel 8 to seal with the dust collecting box 6. The other end of the recycling channel 8 is connected and communicated with the dust box 303, and a second soft rubber ring 82 can also be provided on the other end of the recycling channel 8 to avoid vibration and wear when connected with the dust box 303, which has good vibration reduction effect and improves the sealing of the connection. The first soft rubber ring 81 and the second soft rubber ring 82 can be designed according to the end of the recycling channel 8, which is not limited.

[0068] Further, regarding the structure of the dust collecting box 6, it can include a dust collecting box body 61 and a dust collecting upper cover 62. The dust collecting upper cover 62 is detachably installed on the dust collecting box body 61. The cooperation between the dust collecting upper cover 62 and the dust collecting box body 61 can be a flip type cooperation, for example, one end of the dust collecting upper cover 62 is hinged with one side edge of the top of the dust collecting box body 61, and the other end is fixedly connected with the dust collecting box body 61 through a corresponding lock piece. Those skilled in the art can make appropriate changes and designs according to actual needs, which is not limited. At the same time, in order to make the cooperation between the dust collecting upper cover 62 and the dust collecting box body 61 more sealed and ensure the sealing of the dust collecting box 6, a third soft rubber ring 63 can be arranged between the dust collecting upper cover 62 and the dust collecting box body 61 to improve the sealing of the connection between the dust collecting upper cover 62 and the dust collecting box body 61.

[0069] Further, regarding the fan 5, the suction port 521 is connected and communicated with the dust collecting box 6, and the air supply port 522 is connected with the soundproof box 100. The fan 5 is used for suction treatment in the dust collecting box 6, so that the garbage in the dust box 303 can be sucked into the dust bag 7 through the recycling channel 8 and stored, thereby completing the dust collecting work.

[0070] Further, the dust collecting box 6 is installed on the top of the soundproof box 100 in the present application. Meanwhile, the soundproof box 100 is also provided with a mounting cavity which is isolated from the soundproof cavity 101 and is used for mounting the fan 5. By providing a mounting cavity for mounting the fan 5, the external fan 5 can be embedded in the soundproof box 100, so that the overall structure is more compact.

[0071] Further, regarding the structure of the soundproof box 100, as shown, Figure 3 It includes a soundproof box body 1, a soundproof upper cover 2 and a connecting cylinder frame 3.

[0072] The first annular cylinder wall 12 is integrally formed with the soundproof box body 1, and is not limited.

[0073] The soundproof upper cover 2 is detachably covered on the soundproof box body 1. The soundproof upper cover 2 is detachably installed on the soundproof box body 1 by screws or other fasteners, and the specific manner is not limited. The soundproof upper cover 2 is provided with a relief hole which avoids the first annular cylinder wall 12 and has a diameter larger than that of the first annular cylinder wall 12. Furthermore, the soundproof upper cover 2 is provided with a second annular cylinder wall 21 protruding upward at the edge of the relief hole. The second annular cylinder wall 21 and the first annular cylinder wall 12 form a through gap. The second annular cylinder wall 21 is integrally formed with the soundproof upper cover 2, and is not limited.

[0074] In terms of the structure of the connecting cylinder frame 3, it includes a mounting cylinder 31 and a connecting disc 32. The mounting cylinder 31 is movably embedded in the first annular cylinder wall 12, and the inner cavity of the mounting cylinder 31 forms a mounting cavity. By designing a mounting cylinder 31 separately, the fan 5 is installed, which is more convenient for disassembly and maintenance than directly installing the fan 5 inside the first annular cylinder wall 12. The connecting disc 32 is sleeved on the outer side wall of the mounting cylinder 31 at the upper edge, and is sealingly connected with the top of the first annular cylinder wall 12 and the top of the second annular cylinder wall 21, respectively. The inner wall surface of the soundproof box body 1, the outer wall surface of the first annular cylinder wall 12, the inner wall surface of the second annular cylinder wall 21, and the bottom surface of the connecting disc 32 form a soundproof cavity 101. The connecting disc 32 and the annular cylinder wall can be integrally formed, and are not limited.

[0075] In terms of the air inlet structure 102, it can be provided on the connecting disc 32, and the air outlet structure 103 is provided on the outer side wall of the soundproof box body 1. Those skilled in the art can also make appropriate design changes based on this, and are not limited.

[0076] Further, the fan 5 can be a bypass type dry-wet fan 5. The fan 5 includes a fan body 51 and a wind guide head 52. The wind guide head 52 is installed on the top of the fan body 51. The air suction port 521 of the fan 5 is provided on the top of the wind guide head 52. The air supply port 522 of the fan 5 is a plurality of air supply ports and is annularly arranged on the outer peripheral wall of the wind guide head 52. The bypass type dry-wet fan 5 has a compact and small structure, and is convenient to install and maintain. The specific structure of the bypass type dry-wet fan 5 in the embodiment can refer to the existing bypass type dry-wet fan 5, and is not described in detail.

[0077] Furthermore, taking the application of the bypass-type wet and dry dual-purpose fan 5 as an example, in order to better match the application of the fan 5, the bottom of the dust collection box 6 is provided with a connecting port that communicates with the exhaust port 521 of the fan 5, and the top outer edge of the connecting plate 32 is provided with a first mounting flange 323 protruding upward. Correspondingly, the bottom of the dust collection box 6 is provided with a second mounting flange 611 that is distributed around the connecting port and is sealed to the first mounting flange 323. During installation, the air guide head 52 of the fan 5 is positioned between the first mounting flange 323 and the second mounting flange 611 to ensure the communication between the air outlet 522 and the air inlet structure 102. In this way, the airflow drawn from the dust collection box 6 by the fan 5 through the exhaust port 521 is sent through the air outlet 522 into the space between the first mounting flange 323 and the second mounting flange 611, and then enters the silencer chamber 101 through the air inlet structure 102. With this structural design, the airflow from the air outlet 522 of the fan 5 can first pass through the space buffer between the first mounting flange 323 and the second mounting flange 611, and then flow into the silencing cavity 101 through the air inlet structure 102 of the connecting plate 32. The vibration speed of the airflow is slowed down by the space buffer between the first mounting flange 323 and the second mounting flange 611, which also reduces the noise to a certain extent.

[0078] Furthermore, the bottom of the air guide head 52 is sealed to the connecting cylinder frame 3 via the first sealing element 91; the top is sealed to the bottom of the dust collection box 6 via the second sealing element 92, resulting in better sealing between the air guide head 52, the connecting cylinder frame 3, and the dust collection box 6, allowing a sealed ventilation cavity to be formed between the first mounting flange 323 and the second mounting flange 611. Both the first sealing element 91 and the second sealing element 92 can be made of soft rubber material, and their structure can be designed to adapt to the installation needs between the air guide head 52 and the connecting cylinder frame 3 and the dust collection box 6, without limitation. For example, the first sealing element 91, such as... Figure 2 As shown, the first sealing element 91 is clamped and pressed between the air guide head 52 and the connecting cylinder frame 3 during the installation of the fan 5, thus completing the sealing fit. Similarly, the second sealing element 92 can be placed on top of the air guide head 52. When the dust collection box 6 is installed on the silencer box 100, the bottom of the dust collection box 6 and the air guide head 52 clamp and press against the second sealing element 92, thus completing the sealing fit.

[0079] Further, for the installation and fixation of the connecting cylinder frame 3, the outer circumferential surface of the first installation flange 323 is circumferentially distributed with a plurality of downwardly extending first positioning posts 322, the bottom of the outer circumferential surface of the second annular cylinder wall 21 is circumferentially distributed with a plurality of upwardly extending second positioning posts 22 corresponding to the first positioning posts 322 one by one, and the second positioning posts 22 are provided with first positioning holes 221 for the first positioning posts 322 to be movably clamped into. The connection between the connecting cylinder frame 3 and the soundproof upper cover 2 can be achieved by the insertion cooperation between the first positioning posts 322 and the second positioning posts 22. Those skilled in the art can make appropriate transformation and design based on this without limitation.

[0080] For the installation and cooperation of the first installation flange 323 and the second installation flange 611, the outer circumferential surface of the first installation flange 323 is also circumferentially distributed with a plurality of lug portions 324, and each lug portion 324 is provided with a second positioning hole 325 in the vertical direction. Correspondingly, the outer circumferential surface of the second installation flange 611 is circumferentially distributed with a plurality of third positioning posts 612 movably clamped into the second positioning holes 325 one by one.

[0081] Further, the porous noise reduction material 4 is selected from at least one of soundproof cotton and suction cotton. Of course, it can also be other materials without limitation.

[0082] Further, the air inlet structure 102 can include a plurality of air inlets 321 arranged in an array. The air inlets 321 can be specifically filled and arranged in an array on the connecting disc 32 to achieve an air uniformization effect on the incoming air flow, so that the incoming air flow flows evenly through the porous noise reduction material 4, achieving a better soundproofing effect. The air outlet structure 103 can also include a plurality of air outlets 11 arranged in an array, which can be specifically arranged in an array on the two side walls of the dust collection box body 61.

[0083] As Figure 4 And Figure 5As shown, a base station includes a base station body 201 and a dust collecting device 200. Wherein, taking the example of the base station body 201 used in cooperation with a cleaning robot, the base station body 201 is provided with a working bin 207 for the cleaning robot to enter, and the working bin 207 is provided with a cleaning seat 204, and the cleaning seat 204 is provided with a cleaning groove 205 for cleaning the wiping member 34 of the cleaning robot. In order to achieve better cleaning, a scraping brush 206 in contact with the wiping member 34 can be arranged in the cleaning groove 205, which is not limited in particular. In addition to the dust collecting device 200, the base station is also provided with a water injection device 203 for injecting water into the water box of the cleaning robot or the cleaning groove 205, and a sewage recovery device 202 for recovering sewage in the cleaning groove 205. As for the installation of the dust collecting device 200, the water injection device 203 and the sewage recovery device 202, the three devices can be installed on the top of the base station body 201, and the dust collecting device 200 can be arranged between the water injection device 203 and the sewage recovery device 202, which is not limited. The specific structure of the base station body 201, the water injection device 203 and the sewage recovery device 202 is not the focus of the improvement of the present application, and therefore it is not described in detail.

[0084] As for the structure of the cleaning robot matched with the base station, as shown in Figure 6 and Figure 7 , it includes a robot body 300, a driving wheel 301, a universal wheel 302, a dust box 303 and a wiping member 34, which is not described in detail.

[0085] Taking the example of the base station matched with the cleaning robot, the dust collecting work of the base station is as follows:

[0086] When the cleaning robot detects that the dust box 303 is full of dust or completes the cleaning work of a certain area during the cleaning work, it returns to the base station for dust collection. When the cleaning robot completes the docking work with the base station, the recovery channel 8 of the dust collecting device 200 of the base station is connected and conducted with the dust box 303 of the cleaning robot. At this time, the fan 5 of the dust collecting device 200 starts to work, and the garbage in the dust box 303 of the cleaning robot is sucked into the dust bag 7 in the dust collecting box 6 from the recovery channel 8. The garbage is collected by the dust bag 7, and the air flow continues to enter the muffling cavity 101 through the fan 5, and is discharged after being muffled by the porous noise reduction material 4.

[0087] The dust collecting device and the base station provided by the present application are described in detail above. For those skilled in the art, according to the idea of the embodiments of the present application, there will be changes in specific implementation and application range. In view of the above, the content of the present application should not be understood as a limitation.
