For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] The dust collection bin device in this application is specifically used in a cleaning system. It is mainly used to enhance the suction of the fan in the air ducts before and after the dust collection bin, prevent dust from being completely and fully collected into the dust collection bin due to air leakage or other reasons, and minimize the vibration generated by the fan during operation by improving the layout of each air duct outside the dust collection bin and adding shock-absorbing components.

[0044] See Figures 1-5 The dust collection bin device provided by the present invention includes: a base 1, which serves as the main structure for supporting the body of the dust collection bin 30 and the installation of the fan 50, and realizes the absorption and collection of dust and the transfer of dust into the dust collection bin 30 by setting necessary cavities on the base 1.

[0045] Specifically, the base 1 is provided with a dust collection duct 10, a dust collection bin 30 and a fan 50. In order to make the overall structure more compact, the dust collection bin 30 and the fan 50 are arranged on both sides of the base 1, and the duct that realizes the functions of dust collection, transfer and suction is arranged between the dust collection bin 30 and the fan 50.

[0046] Specifically, the aforementioned functional air ducts include a dust collection duct 10, a transfer duct 20, and a suction duct 40. The dust collection duct 10 is mainly used to draw dust and debris collected by the cleaning system into the dust collection bin 30 using the suction generated by the fan 50. The transfer duct 20 mainly serves a transfer function, absorbing and transferring dust from the dust collection duct 10 to the dust collection bin 30. The suction duct 40, under the suction of the fan 50, provides a certain vacuum suction force to the dust collection bin 30, enabling it to draw dust and debris into the dust collection bin 30.

[0047] The side wall of the dust collection bin 30 is provided with openings that communicate with the transfer air duct 20 and the suction duct 40. A dust filter (not shown in the figure) is provided at the opening that connects to the suction duct 40. The dust filter can intercept dust and garbage in the dust collection bin 30 and prevent the dust and garbage in the dust collection bin 30 from entering the downstream air duct and the fan 50.

[0048] Specifically, the dust collection duct 10 includes a dust collection chamber 12 disposed on the base 1 and a dust collection shell 17 covering the dust collection chamber 12 on the base 1. To enhance sealing and prevent air leakage from the dust collection duct 10 body, and to prevent dust from escaping to the outside of the dust collection duct 10, a dust collection seal 16 is provided between the dust collection shell 17 and the base 1. The base 1 includes a dust collection cover 11 located on its inner wall. The dust collection chamber 12 is mated with the dust collection cover 11 to cover and seal the dust collection chamber 12 on the base 1. The dust collection seal 16 is EVA foam disposed at the mating contour of the dust collection cover 11 and the dust collection chamber 12, which can provide a good sealing effect.

[0049] From the perspective of enhancing the overall structural compactness, the suction duct 40 is installed between the base 1 and the fan 50 and connected to the base 1. The suction duct 40 includes a suction inlet 44 located on its side, which is connected to the side wall of the dust collection bin 30. A fan exhaust port 46 is provided at the top of the suction duct 40 to direct the suction force generated by the fan 50 to the dust collection bin 30 through the suction duct 40. The suction outlet is located at the other end of the suction inlet 44 on the suction duct 40, allowing the airflow to be discharged from the downstream.

[0050] To reduce the vibration generated during the operation of the fan 50, a vibration damping component is installed between the fan 50 and the base 1. This component reduces the impact of the fan 50's vibration on the base 1 and the dust collection bin 30, thereby further reducing the noise generated by the vibration, making the cleaning system cleaner during operation, and improving the user experience.

[0051] In one specific embodiment, the dust collection chamber 12 is the space enclosed by the dust collection hood 11. The dust collection duct 10 includes a dust collection inlet 13 located on the side of the base 1 and disposed on the dust collection hood 11, and a dust collection outlet 14 disposed on the top of the dust collection chamber 12. The dust collection outlet 14 is specifically disposed on the top of the dust collection hood 11. The transfer duct 20 connects the dust collection outlet 14 and the dust collection bin 30. Based on the reliable seal formed by the dust collection seal 16 between the dust collection hood 11 and the dust collection chamber 12, in order to further ensure that dust and other particles escape to the outside before entering the dust collection bin 30, a sealing sleeve 15 is provided at the junction of the dust collection outlet 14 and the transfer duct 20.

[0052] Specifically, the sealing sleeve 15 is an annular clamp with a certain length. The sealing sleeve 15 seals the connection between the dust collection outlet 14 and the transfer duct 20, which can effectively improve the sealing performance of the connection between the dust collection duct 10 and the transfer duct 20. Combined with the dust collection seal set between the dust collection chamber 12 and the dust collection hood 11, it can effectively prevent air leakage and other phenomena, effectively improve the suction power in the dust collection section and the transfer section, and enhance the dust capture ability.

[0053] In this embodiment, the dust collection outlet 14 is a circular hole located on the top of the dust collection hood 11, and the dust collection inlet 13 is a square hole located on the side of the dust collection hood 11. This arrangement expands the dust collection range that the dust collection inlet 13 can capture. Preferably, the ratio between the cross-sectional area of ​​the dust collection outlet 14 and the cross-sectional area of ​​the dust collection inlet 13 is 1:6 to 1:10. In this embodiment, the ratio is specifically 1:8, which can effectively improve the flow state of the dust collection airflow in the dust collection duct 10, reduce the impact of the airflow on the side wall of the duct, and reduce the howling noise generated by the airflow.

[0054] The transfer air duct 20 specifically includes a transfer air inlet 21 and a transfer air outlet 22. The transfer air inlet 21 is connected to the dust collection outlet 14, and the sealing sleeve 15 is clamped at the joint between the two. The transfer air outlet 22 is connected to the side wall of the dust collection bin 30, and the transfer air outlet 22 is directly connected to the internal space of the dust collection bin 30, which allows the transferred dust and debris to be directly collected and collected into the dust collection bin 30.

[0055] In another embodiment, similar to the dust collection channel described above, the suction channel 40 also includes a separately configured suction shell 41 and suction cover plate 42, which together form the suction cavity 43 of the suction channel 40. Specifically, the suction inlet 44 is located on the side of the suction shell 41 and is connected to the side wall of the dust collection bin 30. To enhance the sealing of the connection between the suction channel 40 and the dust collection bin 30, a suction seal 45 is provided between the suction inlet 44 and the dust collection bin 30 to prevent air leakage loss due to poor sealing.

[0056] By cooperating with the suction seal 45 and the dust collection seal, and combined with the sealing sleeve 15 between the dust collection duct 10 and the transfer duct 20, the sealing performance between different ducts and between different ducts and the dust collection bin 30 can be guaranteed, greatly improving the suction power of the overall device, so that dust and garbage can be collected more fully and completely into the dust collection bin 30.

[0057] The suction force of the whole device is transmitted through the fan air inlet 46 set on the top of the suction shell 41. Specifically, the fan air inlet 46 is opposite to the fan 50 and can transmit the suction force generated when the impeller of the fan 50 rotates to the suction channel 40 through the fan air inlet 46, thereby further realizing the air extraction effect.

[0058] From the perspective of reducing the vibration of the overall device, the vibration damping component includes a vibration damping bushing 60 disposed between the fan air inlet 46 and the fan 50. Specifically, the vibration damping bushing 60 is clamped around the fan 50. Preferably, the vibration damping bushing 60 is connected to the base 1, so that the fan 50 and the base 1 can form an integral structure through the vibration damping bushing 60, thereby reducing the resonance generated by the fan 50 during operation and enhancing the vibration damping effect.

[0059] See Figures 6-7 In this embodiment, the fan air inlet 46 is a circular hole located at the top of the suction housing 41, and the suction inlet 44 is a square hole located on the side of the suction housing 41. This increases the suction area of ​​the suction channel 40 on the dust collection bin 30. Simultaneously, the circular fan air inlet 46 aligns the impeller openings on the side of the fan 50 with the impeller openings, allowing the suction force to be more concentrated on the fan air inlet 46, thus improving the suction effect. Preferably, the ratio between the cross-sectional area of ​​the fan air inlet 46 and the cross-sectional area of ​​the suction inlet 44 is 1:20 to 1:30. In this embodiment, the ratio is specifically 1:28. By increasing the area of ​​the suction inlet 44, the impact of the suction airflow on the suction channel 40 can be reduced, thus also reducing whistling noise.

[0060] The shock-absorbing bushing 60 is specifically connected to the base 1. Support blocks 70 for supporting the fan 50 are distributed on the base 1. The distributed support blocks 70 form an open cavity for accommodating the air intake channel 40. The shock-absorbing bushing 60, which is clamped around the fan 50, is connected to the top of the support block 70 and is located above the air intake channel 40. This makes the overall structure more compact and facilitates the connection and installation of the shock-absorbing bushing 60 and the support block 70.

[0061] A connecting post 71 is provided on the top of the support block 70, and a mounting hole 72 with internal threads is provided on the connecting post 71. A connecting hole 61 is provided on the circumferential outer side of the shock-absorbing bushing 60. A shock-absorbing pad 62 is provided between the shock-absorbing bushing 60 and the connecting post 71. The mounting hole 72, the shock-absorbing pad 62 and the connecting post 71 are in a one-to-one correspondence, and the shock-absorbing pad 62 is a flexible hollow column structure.

[0062] During installation, the vibration damping pad 62 is first placed on top of the connecting column 71. Then, screws are passed through the connecting hole 61, the vibration damping pad 62, and the mounting hole 72 in sequence, and the vibration damping bushing 60 is installed on the connecting column 71 by screwing. The vibration damping pad 62, made of flexible materials such as silicone or rubber, can effectively buffer the vibration generated by the fan 50 at the connection point, reduce the lateral vibration of the fan 50, and effectively improve the suction conditions.

[0063] Preferably, in order to prevent vibration between the fan 50 and the shock-absorbing bushing 60, the shock-absorbing bushing 60 in this embodiment is installed on the periphery of the motor in the form of an interference fit, so that the two form an integral structure. Furthermore, by combining the connection between the shock-absorbing bushing 60 and the base 1, the impact of the fan 50 vibration can be reduced to the greatest extent, the noise caused by vibration can be reduced, and the user experience can be improved.

[0064] In addition to EVA foam, the dust suction seal 16 and the air suction seal 45 can also be made of flexible materials such as silicone or rubber, which can also achieve the technical purpose of improving the sealing performance of the overall device.

[0065] The present invention also provides a cleaning system including the above-mentioned dust collection bin device, which can effectively enhance the suction power of the fan, improve the dust collection effect, reduce the noise of use, and significantly improve the user experience.

[0066] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
