Detailed Implementation
[0046] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0047] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0048] A first aspect of this application provides an exhaust component mounting structure 1100. Please refer to [link / reference]. Figure 1 and Figure 2 The diagram shows the overall structure and exploded view of the exhaust assembly mounting structure 1100. The exhaust assembly mounting structure 1100 includes an exhaust assembly 200 and a mounting base 1110 for fixing the exhaust assembly 200. The exhaust assembly 200 includes a fan 210 and an air duct 220. When the fan 210 is working, it draws in air from the inlet of the air duct 220 and draws it out, thereby creating a negative pressure inside the chamber connected to the inlet of the air duct 220. The exhaust assembly 200 can be used in the automatic cleaning equipment 1000 as a negative pressure source for the vacuuming device of a sweeping robot, or as a negative pressure source for the dust collection module 2100 of a base station; this application does not impose any limitations.
[0049] The fan 210 is connected to the inner cavity 220a of the duct 220, and can draw air through the duct 220 to create negative pressure. Please refer to... Figure 1 The air duct 220 is connected to and fixedly installed on the mounting base 1110. The fan 210 is mounted on the air duct 220, specifically, at least a portion of the fan 210 is located on and supported by the air duct 220. It can be completely located on the air duct 220 and thus not in contact with the mounting base 1110; or a portion of the fan 210 can be located on the air duct 220, with the remaining portion separated from and not in contact with the mounting base 1110; or a portion of the fan 210 can be located on the air duct 220, with the remaining portion located on the mounting base 1110. The fan 210 is connected to the air duct 220 and / or the mounting base 1110. It can be fixedly connected only to the air duct 220, only to the mounting base 1110, or simultaneously connected to both the air duct 220 and the mounting base 1110.
[0050] To achieve vibration reduction and noise reduction, please refer to [link / reference]. Figure 2At least one of the following locations is provided: the connection point between the fan 210 and the duct 220, and the connection point between the fan 210 and the duct 220 and / or the mounting base 1110. To stably fix the fan 210, the number of connection points of the fan 210 should be at least two. That is, at least one of the connection points between the fan 210 and other components, or at two or more connection points, is provided with a flexible damping element 1120. The connection points between the fan 210 and other components are the main points of vibration transmission. By providing a flexible damping element 1120 at these locations, the flexible damping element 1120 can weaken vibration transmission using its flexible structure, thereby reducing noise.
[0051] Figure 3 A schematic diagram is shown showing a flexible damping element 1120 installed at the connection between the fan 210 and the duct 220 in some embodiments. Please refer to... Figure 3 The flexible damping element 1120 here is a sealing gasket 1121. The sealing gasket 1121 is sandwiched at the connection between the fan 210 and the air duct 220. It not only reduces the transmission of vibration, but also uses its compressible and deformable characteristics to seal the gap between the fan 210 and the air duct 220. The material of the sealing gasket 1121 can be silicone, rubber, etc., and this application does not impose any restrictions.
[0052] Please see Figure 4 In some embodiments, the sealing gasket 1121 has a hollow structure 11211. The cavity formed by the hollow structure 11211 can effectively increase buffering, absorb vibration energy, weaken vibration, and further improve the vibration reduction and noise reduction effect. The hollow structure 11211 can be a plurality of through holes penetrating the sealing gasket 1121 along the thickness direction of the sealing gasket 1121; it can also be a groove with an opening on one side, the opening of which can all face one side of the sealing gasket 1121, or grooves can be arranged on both sides of the sealing gasket 1121. Because the sealing gasket 1121 has a hollow structure 11211, the sealing gasket 1121 of this application uses less material and is lighter for the same size. Using the same amount of material, a thicker sealing gasket 1121 can be obtained. When there is sufficient installation space, the thickness of the sealing gasket 1121 can be increased, further improving the vibration reduction effect.
[0053] Figure 5 This diagram illustrates a structure in some embodiments where a flexible damping element 1120 is provided at the connection between the fan 210 and the duct 220 and / or the mounting base 1110. Please refer to the diagram for further details. Figure 5The fan 210 has three connection points, two of which are used to connect to the air duct 220, and the remaining connection point is used to connect to the mounting base 1110. The flexible shock absorber 1120 at the connection point of the fan 210 is a soft rubber sleeve 1122. The fan 210 is connected to the air duct 220 and the mounting base 1110 by screws 1160, and the soft rubber sleeve 1122 is fitted around the screw 1160.
[0054] For easy connection of the fan 210 to the duct 220 and the mounting base 1110, please refer to [link / reference needed]. Figure 5 In some embodiments, both the air duct 220 and the mounting base 1110 are provided with mounting posts 1130 with threaded holes, and the fan 210 is provided with a connecting part 1140a. The screw 1160 passes through the connecting part 1140a and the soft rubber sleeve 1122, and extends into the threaded hole to be threadedly connected to the mounting post 1130. The soft rubber sleeve 1122 is limited and abuts against the air duct 220 and the mounting base 1110, thereby making the fixing part in flexible contact with the air duct 220, the fixing part in contact with the fixing base 1110, and the fixing part in contact with the screw 1160, which can effectively block the transmission of vibration.
[0055] The connecting part 1140a of the fan 210 can be a mounting lug provided on the volute of the fan 210, or it can be an independently provided part; this application does not impose any restrictions. Please refer to Figure 5 and Figure 6 In some embodiments, the exhaust assembly mounting structure 1100 further includes a pressure cap 1140. The pressure cap 1140 is located on the side of the fan 210 away from the mounting base 1110. The pressure cap 1140 is connected to the mounting base 1110 and / or the air duct 220 to press the fan 210 tightly onto the air duct 220, thereby forming a connection part 1140a of the fan 210. Since the pressure cap 1140 presses the fan 210, when a sealing gasket 1121 is provided between the fan 210 and the air duct 220, the fan 210 presses the sealing gasket 1121 under the pressure of the pressure cap 1140, achieving a sealing effect. By setting the pressure cap 1140 to fix the fan 210, the fan 210 itself does not need to be fixed, and commercially available fans 210 can be used directly, making the fan 210 more versatile.
[0056] The gland 1140 presses against the blower 210, and the gland 1140 and the blower 210 are in rigid contact. Vibrations from the blower 210 are directly transmitted to the gland 1140. Please refer to [link / reference]. Figure 2In some embodiments, a shock-absorbing pad 1150 is provided between the pressure cap 1140 and the fan 210. The material of the shock-absorbing pad 1150 can be silicone, rubber, foam, etc., and this application does not impose any restrictions. By providing a shock-absorbing pad 1150 between the pressure cap 1140 and the fan 210, the pressure cap 1140 and the fan 210 also have flexible contact, reducing the vibration transmitted to the pressure cap 1140. Since the shock-absorbing pad 1150 itself can absorb shock and energy, in this embodiment, the material of the pressure cap 1140 is not required. The material of the pressure cap 1140 can be silicone, latex, rubber (e.g., nitrile rubber), plastic, metal, etc. For embodiments without a shock-absorbing pad 1150, the pressure cap 1140 can be made of a material with a certain degree of elasticity, such as silicone, latex, or rubber (e.g., nitrile rubber), or plastic.
[0057] Since the pressure cap 1140 constitutes the connection part 1140a of the fan 210, the corresponding flexible damping element 1120, which is provided at the connection point of the fan 210, is specifically located at the connection between the pressure cap 1140 and the fixed base 1110 and / or the air duct 220, thereby blocking the vibration transmitted by the pressure cap 1140. The structure of the flexible damping element 1120 located at different connection points can be the same or different, and a suitable soft rubber sleeve 1122 can be selected according to specific usage requirements. Please refer to... Figure 7 and 9 The diagrams show the connection structure of the soft rubber sleeve 1122 and the pressure cap 1140 in different embodiments. In general, the soft rubber sleeve 1122 is a cylindrical sleeve structure with a circumferentially surrounding annular groove 11221 on its outer surface. The pressure cap 1140 has a corresponding limiting ring 1141 that matches the annular groove 11221. The soft rubber sleeve 1122 is positioned relative to the pressure cap 1140 via the annular groove 11221 and the limiting ring 1141. The portion of the soft rubber sleeve 1122 away from the pressure cap 1140 abuts against the air duct 220 and the fixing seat 1110. The following will describe the soft rubber sleeve 1122 with different structures in detail with reference to the accompanying drawings.
[0058] Please combine Figure 7 and Figure 8In some embodiments, the soft rubber sleeve 1122 is a cylindrical sleeve structure. The upper part of the outer surface of the soft rubber sleeve 1122 is provided with an annular groove 11221, and the middle part of the inner wall is provided with a guide boss 11222. The size of the cylinder cavity is reduced at the guide boss 11222 and matches the diameter of the stud 1162 of the screw 1160, so that when the screw 1160 passes through the guide boss 11222, the guide boss 11222 plays a certain guiding role for the screw 1160, and the head 1161 of the screw 1160 is engaged on the stepped surface 11224 formed by the guide boss 11222. In some embodiments, the guide boss 11222 and the annular groove 11221 are offset in the axial direction of the soft rubber sleeve 1122, and the distance between them is greater than the height of the head 1161 of the screw 1160. This allows the head 1161 of the screw 1160 and the annular groove 11221 to also be offset in the axial direction of the soft rubber sleeve 1122. The soft rubber sleeve 1122 can absorb not only axial vibrations but also radial vibrations, further improving the damping effect. In some embodiments, the bottom of the soft rubber sleeve 1122 is provided with an enlarged hole 11223, which is fitted onto the mounting post 1130. The bottom of the enlarged hole 11223 abuts against the top surface of the mounting post 1130, and the edge of the enlarged hole 11223 abuts against the air duct 220 and the fixing seat 1110.
[0059] Please combine Figure 9 and Figure 10 In other embodiments, the soft rubber sleeve 1122 is a cylindrical sleeve structure with a straight circular hole in its cavity. An annular groove 11221 is located in the middle of the soft rubber sleeve 1122. During installation, the soft rubber sleeve 1122 is inserted into the limiting ring 1141, and the limiting ring 1141 is embedded in the annular groove 11221, thereby limiting the distance between the pressure cap 1140 and the soft rubber sleeve 1122, allowing the soft rubber sleeve 1122 to be stably placed on the pressure cap 1140. The head 1161 of the screw 1160 is larger than the cavity size of the soft rubber sleeve 1122, allowing the stud 1162 of the screw 1160 to extend into the cavity of the soft rubber sleeve 1122, but the head 1161 of the screw 1160 is blocked. The head 1161 of the screw 1160 does not contact the gland 1140. The stud 1162 is threadedly engaged with the mounting post 1130 of the fixing seat 1110 and the air duct 220. The bottom end of the soft rubber sleeve 1122 abuts against the air duct 220 and the fixing seat 1110, so that the gland 1140 is in flexible contact with the air duct 220, the fixing seat 1110 and the screw 1160.
[0060] In this application, the fan 210 is mounted on the duct 220, allowing the fan 210 to be supported by the larger wall surface of the duct 220, thus making the structure of the exhaust assembly 200 more compact. To reduce the size of the exhaust assembly 200, the fan 210 should be in contact with the duct 220 without any gap between them. However, once the fan 210 is in contact with the duct 220, vibrations will be directly transmitted to the duct 220. Since the duct 220 has a large internal cavity 220a, it is prone to resonance, amplifying noise. Therefore, please refer to [reference needed]. Figure 11 and Figure 12 The side wall of the air duct 220 near the fan 210 is provided with a support rib 221. The support rib 221 can improve the rigidity of the side wall and effectively suppress vibration and reduce abnormal noise caused by resonance.
[0061] The air duct 220 is equipped with an air inlet 220b and an air outlet 220c, with the air outlet 220c connected to the exhaust port of the fan 210. Please refer to... Figure 11 and Figure 12 In some embodiments, the opening size of the air outlet 220c is smaller than the opening size of the air inlet 220b, and the height of the air outlet 220c is smaller than the height of the air inlet 220b, making the exhaust duct 200a have a larger inlet and smaller outlet shape, thus improving the exhaust effect. The top wall 222 of the duct 220 is inclined and has a large area. The fan 210 is located above the top wall 222, and the large area of the top wall 222 can stably support the fan 210. Correspondingly, the support rib 221 should be connected at least to the top wall 222 of the duct 220. Considering the large height of the air inlet 220b, in some embodiments, the top of the fan 210 or the cover 1140 can be set not higher than the top of the air inlet 220b, such as... Figure 13 As shown, the space occupied by the air duct 220 itself can be used to arrange the fan 210 and the cover 1140.
[0062] Please see Figure 12 and Figure 15 In some embodiments, the air inlet 220b of the air duct 220 is provided with a grille 224. The grille 224 serves two purposes: firstly, it enhances the overall rigidity of the air duct 220; secondly, it supports the filter after it is installed in the cleaning equipment; and thirdly, it prevents larger foreign objects from entering the air duct 220 after the filter is removed. Support ribs 221 connect the top wall 222 and the grille 224, providing support for the relatively large area of the top wall 222 and the grille 224, thus enhancing their rigidity. In some embodiments, the support ribs 221 can be configured as several spaced-apart guide plates that extend along the exhaust direction, serving a guiding function.
[0063] In some embodiments, the air duct 220 may be a separate component, with its inner cavity 220a forming the exhaust channel 200a. In other embodiments, the exhaust channel 200a may also be formed by the air duct 220 and other components. Please refer to the following for details. Figure 12 The side of the air duct 220 near the fixed base 1110 is an open opening 220d. In the embodiment where the air inlet 220b of the air duct 220 is provided with a grille 224, the side of the air duct 220 near the fixed base 1110 is set as an open structure, so that the air duct 220 can be integrally molded by injection molding, which is convenient for demolding.
[0064] Please see Figure 14 The fixed base 1110 has an outwardly protruding part 1111 that matches the shape of the opening 220d. The air duct 220 is fitted onto the outwardly protruding part 1111 through the opening 220d, so that it and the fixed base 1110 together form an exhaust channel 200a. Figure 15 As shown. The inner wall of the opening 220d of the air duct 220 fits against the outer wall of the protrusion 1111, which can also serve as a seal. Therefore, no sealing structure is required between the air duct 220 and the fixed seat 1110.
[0065] In some embodiments, the exhaust assembly 200 is applied to the cleaning device 1000 of the automatic cleaning system 3000 to draw waste into the dust storage chamber 100a of the cleaning device 1000. The waste in the dust storage chamber 100a is automatically collected by the dust collection base station 2000 of the automatic cleaning system 3000. Specifically, the cleaning device 1000 is provided with a dust outlet channel 300 communicating with the dust storage chamber 100a, through which the waste in the dust storage chamber 100a enters the dust collection base station 2000. Please refer to [link to relevant documentation]. Figure 16 In some embodiments, the air duct 220 is provided with a mounting groove 223 with a through opening. The mounting groove 223 is used to install the dust outlet channel 300, which is connected to the mounting groove 223 and communicates with the through opening. By fixing the dust outlet channel 300 through the air duct 220, the air duct 220 and the dust outlet channel 300 can be pre-assembled into a sub-assembly during assembly, and then uniformly installed on the equipment body 100 of the cleaning equipment 1000, facilitating assembly. Furthermore, the dust outlet channel 300, the air duct 220, and the equipment body 100 can be connected using the same fastener, reducing the number of fasteners required.
[0066] In summary, the exhaust assembly installation structure 1100 provided in this application reduces noise by incorporating flexible damping components 1120 at vibration transmission points, thereby reducing vibration transmission through flexibility; it also increases the rigidity of the duct 220 by providing support ribs 221 on the side wall of the duct 220 near the fan 210, effectively suppressing vibration and reducing abnormal noise caused by resonance; and it further reduces vibration by incorporating a damping pad 1150 between the pressure cover 1140 and the fan 210, ensuring flexible contact between them. These structural features result in quieter operation of the fan 210 during startup, improving the user experience.
[0067] By incorporating at least one of the aforementioned flexible damping element 1120, damping pad 1150, and support rib 221, exhaust assembly mounting structures 1100 of different embodiments can be obtained. Comparative tests were conducted between the exhaust assembly mounting structures 1100 of different embodiments of this application and existing technologies. Sample 1 served as a control group, without the flexible damping element 1120, damping pad 1150, and support rib 221; Sample 2 represented one embodiment of this application, incorporating the flexible damping element 1120, damping pad 1150, and support rib 221; Sample 3 represented another embodiment of this application, incorporating only the flexible damping element 1120. All three samples operated at the same power, and the vibration frequency and noise curves are shown below. Figure 17A , Figure 17B and Figure 17C As shown, according to Figure 17A , Figure 17B and Figure 17C It can be seen that, compared with sample one, the first octave amplitude of fan 210 in sample two is reduced by 5.8 dB, and the first octave amplitude of fan 210 in sample three is reduced by 5.1 dB. The audible "humming" noise of samples two and three at the test site is significantly improved. After testing, the exhaust component installation structure 1100 provided in this application has good vibration reduction and noise reduction effect.
[0068] Please see Figure 18 , Figure 19 and Figure 20 According to a second aspect of this application, a cleaning device 1000 is provided, which can be a robotic vacuum cleaner or a floor scrubber.

The suction assembly mounting structure 1100 is mounted on the device body 100. The device body 100 has a dust storage chamber 100a with a suction port 100b. A suction assembly 200 is connected to the dust storage chamber 100a. When a fan 210 is started, it draws air from the dust storage chamber 100a through an air duct 220, so that dust and debris are drawn into the dust storage chamber 100a from the suction port 100b.
[0069] The mounting bracket 1110 of the exhaust assembly mounting structure 1100 is connected to the device body 100, so that the exhaust assembly mounting structure 1100 is entirely mounted on the device body 100. The mounting bracket 1110 can be a component independent of the device body 100, or the device body 100 can be used as the mounting bracket 1110 of the exhaust assembly mounting structure 1100. Please refer to [link / reference]. Figure 19 and Figure 20 In some embodiments, the device body 100 includes a connected base and a top cover 110. The base forms a fixed seat 1110, and the exhaust assembly 200 is mounted on the base and located in the space enclosed by the base and the top cover 110.

The exhaust assembly 200 is installed in the housing of the dust collection base station 2000, meaning that the housing of the dust collection base station 2000 serves as the fixing seat 1110 of the exhaust assembly mounting structure 1100. When the cleaning equipment 1000 enters the dust collection base station 2000 and the dust collection base station 2000 is in dust collection mode, the dust storage chamber 100a of the cleaning equipment 1000 is connected to the dust inlet channel 2120 of the dust collection module 2100. The debris in the dust storage chamber 100a is sucked into the dust bag 2110 under the action of negative pressure. After the debris in the dust storage chamber 100a is emptied, the cleaning equipment 1000 leaves the dust collection base station 2000 and continues to clean the dust and debris in the area.
