[0030] Referring to Figures 1-8 , the present utility model discloses a filtering device, which includes a base 1, a filtering mechanism, a noise reduction assembly and a fan 10 installed on the top of the base 1. The noise reduction assembly is used to reduce the noise of the fan 10. The fan 10 is installed in the noise reduction assembly, and a base air outlet 11 is provided at the bottom of the base 1.

[0031] The noise reduction assembly includes a first noise reduction member 4 and a second noise reduction member 5. The fan 10 is respectively installed in the first noise reduction member 4 and the second noise reduction member 5. The first noise reduction member 4 is provided with an air inlet groove 41, and the second noise reduction member 5 is provided with an air guide port 51. The filtering mechanism, the air inlet groove 41, the fan 10, the air guide port 51 and the base air outlet 11 are connected in sequence.

[0032] In this utility model filtering device, the fan is installed inside the first noise reduction component and the second noise reduction component, which can not only reduce the noise generated during the operation of the fan, but also play a role in fixing the fan. At the same time, the setting of the two noise reduction components facilitates the installation of the fan. The air outlet of the base is located at the bottom of the base, which can discharge the filtered gas to the bottom of the filtering device or even the equipment, reducing problems such as large occupied space caused by setting the air outlet on the side, and is beneficial for storage and transportation.

[0033] Among them, the fan 10 can adopt the existing technical structure, and its specific structure will not be introduced in detail. Specifically, the fan can adopt a brushless vacuum cleaner fan produced by Nidec Corporation, with the model of 11F220Q220.

[0034] Specifically, both the first noise reduction component 4 and the second noise reduction component 5 are made of foam. The foam can reduce the noise generated by the vibration of the fan, play a certain sound insulation role, and also reduce the components used to install the fan.

[0035] Preferably, as Figures 1-4 shown, the noise reduction assembly further includes a mounting seat 6, and both the first noise reduction component 4 and the second noise reduction component 5 are installed inside the mounting seat 6. The setting of the mounting seat plays a role in protecting the first noise reduction component and the second noise reduction component.

[0036] Preferably, as Figures 1-4 shown, the filtering mechanism includes a filter seat 3. The filter seat is provided with a filter consumable bin 32 for accommodating the filter consumables 2. The filter seat 3 is connected to the first noise reduction component 4, and the filter consumable bin 2 is communicated with the air inlet groove 41. The filter seat is provided with an air inlet and an air outlet respectively communicated with the filter consumable bin. The smoke generated during the operation enters the filter consumable bin through the air inlet under the action of the fan, and then flows out from the air outlet after passing through the filter consumables in the filter consumable bin. The filter consumable bin is communicated with the air inlet groove through the air outlet. Among them, the filter consumables can adopt existing materials, such as activated carbon, non-woven fabric, and filter cotton, etc. In order to prevent air leakage between the filter seat and the filter consumables, a sealing ring (not shown in the figure) for sealing is provided inside the filter consumable bin 2.

[0037] More preferably, as Figure 5 shown, the first noise reduction component 4 is provided with a connecting groove 42 and a fixing groove 43. The connecting groove 42 is communicated with the air inlet groove 41; the filter seat 3 is provided with a plug-in part 31, and the filter seat 3 is embedded in the connecting groove 42, and the plug-in part 31 is inserted into the fixing groove 43. The connecting groove penetrates the end face of the first noise reduction component and the air inlet groove, that is, the air inlet groove is located at the bottom of the connecting groove. Specifically, the filter seat 3 and the connecting groove 42 are in interference fit, so that a sealing effect is achieved between the filter seat and the first noise reduction component, and the filter seat and the first noise reduction component are fixedly connected by inserting the plug-in part into the fixing groove of the first noise reduction component, thereby ensuring the fixed connection between the filter consumable bin and the first noise reduction component.

[0038] Preferably, as Figures 5-6 shown, the first noise reduction member 4 is provided with a first mounting hole 45 communicating with the air inlet groove 41, the second noise reduction member 5 is provided with a second mounting hole 52 communicating with the air guiding port 51 and a limiting member 53 arranged corresponding to the second mounting hole 52, the fan 10 is respectively installed in the first mounting hole 45 and the second mounting hole 52, and the fan 10 abuts against the limiting member 53. The front half of the fan is placed in the first mounting hole, and the air inlet of the fan is communicated with the air inlet groove; the rear half of the fan is placed in the second mounting hole, and the air outlet of the fan is communicated with the air guiding port. At the same time, in order to fix the fan in the first mounting hole and the second mounting hole, the second noise reduction member is further provided with a limiting member to prevent the fan from detaching from the first noise reduction member and the second noise reduction member.

[0039] Preferably, as Figure 2 、 5 shown, the first noise reduction member 4 is provided with an air inlet channel 44 communicating with the air inlet groove 41; the base 1 is provided with an air outlet channel 12 and a supplementary air channel 13, the air guiding port 51 is communicated with the base air outlet 11 through the air outlet channel 12, and the supplementary air channel 13 is communicated with the air inlet channel 44; as Figures 2-4 shown, the base 1 is provided with a one-way valve 9, and the supplementary air channel 13 is communicated with the outside through the one-way valve 9. Under the action of the fan, the gas after passing through the filter consumable bin flows out from the guiding port of the second noise reduction member and is guided to the base air outlet through the air outlet channel, that is, discharged from the bottom of the filtering device.

[0040] In order to prevent the filter consumable bin from being blocked due to too much filter material, so that the air inlet of the fan cannot intake air, thereby damaging the fan, the present utility model further provides a one-way valve. When the pressure in the air inlet groove is too low, the one-way valve will automatically open, so that the outside air sequentially flows through the supplementary air channel and the air inlet channel and enters the air inlet groove, thereby protecting the fan. Among them, the one-way valve can adopt the existing technical structure and will not be introduced in detail here.

[0041] Further, as Figures 7-8 shown, the present utility model further includes an exhaust duct 7 and an air outlet seat 8, the base 1, the exhaust duct 7 and the air outlet seat 8 are connected in sequence; the exhaust duct 7 is provided with an exhaust channel (not shown in the figure), the air outlet seat 8 is provided with an exhaust port 88, and the base air outlet 11 is communicated with the exhaust port 88 through the exhaust channel. In order to install the filtering device on the frame of the waste collection equipment and make the discharged gas discharged from the bottom of the frame without affecting the normal operation of the equipment and occupying too much space, the present utility model further includes an exhaust duct and an air outlet seat, the base, the exhaust duct and the air outlet seat are connected in sequence, the base air outlet, the exhaust channel and the exhaust port are communicated in sequence, and the air outlet seat is arranged at the bottom of the frame, thereby discharging the gas from the bottom of the frame.

[0042] Preferably, as Figure 8 shown, the air outlet base 8 is provided with a third noise reduction member 81. An air inlet cavity 82, a first air passage 84, a second air passage 86 and a third air passage 87 are arranged in the third noise reduction member 81. The exhaust air passage, the air inlet cavity 82, the first air passage 84, the second air passage 86, the third air passage 87 and the air outlet 88 are communicated in sequence. Specifically, the air outlet base 8 includes a housing and a third noise reduction member 81 arranged in the housing. The third noise reduction member 81 is made of foam. The gas discharged from the exhaust air passage first enters the air inlet cavity, and then flows through the first air passage, the second air passage and the third air passage in sequence, and finally is discharged from the air outlet. The arrangement of these air passages increases the travel of the gas flow, can reduce the wind speed, and thus plays a role in noise reduction.

[0043] More preferably, the air inlet cavity 82 is communicated with the first air passage 84 through a first bend 83, and the first air passage 84 is communicated with the second air passage 86 through a second bend 85; the side walls of the first bend 83, the second bend 85 and the third air passage 87 are wavy side walls. The setting of the bends can reduce the wind speed. The setting of the wavy side walls can reduce the impact force of the two collisions, thereby reducing the noise generated thereby.

[0044] Correspondingly, as Figure 7 shown, the present invention also discloses a waste collection device, which includes a frame 100 and the above-mentioned filtering device, and the base 1 is fixedly installed on the frame 100. The specific structure of the filtering device is as described above and will not be repeated here. Among them, as Figure 7 shown, the exhaust duct 7 is arranged on the frame 100 and extends to the top and bottom of the frame 100 respectively; the base 1 is arranged on the top of the frame 100, and the air outlet base 8 is arranged on the bottom of the frame 100. The exhaust duct 7 is respectively connected to the base 1 and the air outlet base 8, so as to discharge the discharged gas from the bottom of the frame, which not only makes the noise reduction effect of the device good, but also makes the occupied space of the device small.

[0045] In summary, the present invention provides a filtering device and a waste collection device, which have good noise reduction effect and small occupied space.

[0046] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
