[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 4 As shown, an embodiment of the present invention provides a dust removal and deodorization device, which includes an air intake mechanism 10, a dust removal mechanism 20, a deodorization mechanism 30, a circulation detection mechanism 40 and a processing mechanism 50 which are arranged in sequence. The dust removal mechanism 20 includes a dust removal box 21 having an upper vacant area and a lower dust removal area, wherein the dust removal area has a dust removal medium, and the top of the dust removal box 21 away from the air intake mechanism 10 has a first transfer tube 61 which is connected to the inlet of the deodorization mechanism 30; the air intake mechanism 10 includes a first electronic nose sensor 11, a first pipeline 12 and a first switching member 13, and the first electronic nose sensor 11 is provided The circulation detection mechanism 40 comprises a second electronic nose sensor 41, a second pipeline 42 and a second switching member 43. The inlet of the second pipeline 42 is connected to the outlet of the deodorization mechanism 30. The second electronic nose sensor 41 is arranged on the inlet side of the second pipeline 42. The second switching member 43 switches the outlet of the second pipeline 42 to be connected to one of the processing mechanism 50 and the first pipeline 12 according to the detection situation of the second electronic nose sensor 41.

[0032] In this embodiment, the first electronic nose sensor 11 detects the air in the environment where the dust removal and deodorization device is located. When the first electronic nose sensor 11 detects that the air needs to be dusted and deodorized, the dust removal and deodorization device works and sucks air from the inlet side of the first pipe 12, and the first switching component 13 connects the outlet of the first pipe 12 to the dust removal area. The air is first dusted by the dust removal medium in the dust removal area and then discharged from the first transfer pipe to the deodorization mechanism 30 for deodorization; when the first electronic nose sensor 11 detects that the air only needs to be deodorized, the dust removal and deodorization device works and sucks air from the inlet side of the first pipe 12, and the first switching component 13 connects the outlet of the first pipe 12 to the vacant area. The air directly passes through the vacant area and is discharged from the first transfer pipe to the deodorization mechanism 30 for deodorization. When the air discharged after deodorization passes through the circulation detection mechanism, the second electronic nose sensor 41 will detect it again. When the second electronic nose sensor 41 detects that the air quality is still not up to standard, the second switching element 43 connects the outlet of the second pipeline 42 to the first intake pipe to remove dust and deodorize the air again; when the second electronic nose sensor 41 detects that the air quality is up to standard, the second switching element 43 connects the outlet of the second pipeline 42 to the processing mechanism 50, and the qualified air is discharged from the dust removal and deodorization device after being processed by the processing mechanism 50. In this way, through the cooperation of the first electronic nose sensor 11 and the first switching element 13, the dust removal and deodorization device is switched between the deodorization mode and the deodorization + dust removal mode, so that the dust removal and deodorization device can choose whether to perform dust removal according to the pollution degree of the intake air, avoiding the dust removal and deodorization in the prior art. After the dust removal and deodorization device is turned on, the dust removal and deodorization are always carried out simultaneously, which is easy to cause waste of resources, which is conducive to saving resources on the basis of ensuring the cleaning effect of the air. On the other hand, through the cooperation of the second electronic nose sensor 41 and the second switching element 43, the air that has completed dust removal and deodorization can be switched between circulation and discharge, so that the air in the dust removal and deodorization device is not discharged until the treatment meets the standards. This is beneficial to ensure the reliability of air treatment and avoid direct discharge if the treatment does not meet the standards.

[0033] It can be understood that the number of the first electronic nose sensors 11 can be adjusted according to actual conditions, such as in the present embodiment, there is one first electronic nose sensor 11; similarly, the number of the second electronic nose sensors 41 can be adjusted according to actual conditions, such as in the present embodiment, there are multiple second electronic nose sensors 41, namely, a second electronic nose sensor group.

[0034] like Figure 1As shown, the first switching member 13 is a first three-way valve, and the first pipeline 12 includes a first air inlet pipe 121, a first air outlet pipe 122 and a second air outlet pipe 123 respectively connected to the first three-way valve, and the end of the first air inlet pipe 121 away from the first three-way valve is the inlet side of the first pipeline 12 having a placement area, and the first electronic nose sensor 11 is arranged in the placement area, and the ends of the first air outlet pipe 122 and the second air outlet pipe 123 away from the first three-way valve are connected to the dust removal area and the vacant area respectively, and the air intake mechanism 10 also includes a first fan 14 arranged on the first air inlet pipe 121, and the first fan 14 is used to form a wind flow from the first air inlet pipe 121 to the first air outlet pipe 122 and the second air outlet pipe 123.

[0035] In this embodiment, the first pipeline 12 is a three-way pipeline and the two outlets are always connected to the vacant area and the dust removal area, which is conducive to ensuring the reliability of gas flow to the vacant area and the dust removal area. The first three-way valve controls the first air inlet pipe 121 to be connected to one of the first air outlet pipe 122 and the second air outlet pipe 123, which is convenient to adjust and reliable to switch. On the other hand, in this embodiment, the first fan 14 forms a suction airflow in the first pipeline 12 to achieve the suction of air in the environment and improve the air purification efficiency. Combined with the automatic guidance of the first three-way valve to the intake, manual intervention is further reduced, and the fluctuation of air quality caused by manual operation errors is reduced or avoided, ensuring the continuity and reliability of air treatment while ensuring the air treatment effect and efficiency.

[0036] Preferably, the first fan 14 can adjust the air volume according to actual needs, further optimizing energy use, and is suitable for scenarios where the purification capacity needs to be adjusted at different time periods or different work intensities.

[0037] like Figure 1 As shown, the second switching member 43 is a second three-way valve, the second pipeline 42 includes a second air inlet pipe 421, a third air outlet pipe 422 and a fourth air outlet pipe 423 respectively connected to the second three-way valve, and the first air inlet pipe 121. The circulation detection mechanism 40 also includes a detection box 45 and a second fan 44 arranged on the second air inlet pipe 421. The second fan 44 is used to form an air flow from the second air inlet pipe 421 to the third air outlet pipe 422 and the fourth air outlet pipe 423. The detection box 45 is arranged between the outlet of the deodorization mechanism 30 and the inlet of the second air inlet pipe 421. The second electronic nose sensor 41 is arranged in the detection box 45. The ends of the third air outlet pipe 422 and the fourth air outlet pipe 423 away from the second three-way valve are connected to the processing mechanism 50 and the first air inlet pipe 121 respectively.

[0038] In this embodiment, the second pipeline 42 is a three-way pipeline and the two outlets are always connected to the processing mechanism 50 and the first air inlet pipe 121, which is conducive to ensuring the reliability of the gas flow to the processing mechanism 50 and the first air inlet pipe 121. The second three-way valve controls the second air inlet pipe 421 to be connected to one of the third air outlet pipe 422 and the fourth air outlet pipe 423, which is convenient for adjustment and reliable switching. The inlet of the detection box 45 is connected to the outlet of the deodorizing tank 31 through the third transfer tube 63. The air discharged from the deodorizing tank 31 enters the detection box 45 and is detected by the second electronic nose sensor 41 to see if it meets the standard. The inlet of the first air inlet pipe 121 is connected to the outlet of the detection box 45. The area in the detection box 45 can be understood as the inlet side of the first air inlet pipe 121. On the other hand, in this embodiment, a suction airflow is formed in the second pipeline 42 by the second fan 44, so as to absorb the air exhausted from the detection box 45 and the deodorization mechanism 30, thereby improving the air circulation and circulation speed. Combined with the automatic guidance of the intake air by the second three-way valve, manual intervention is further reduced, and air quality fluctuations caused by manual operating errors are reduced or avoided, thereby ensuring the continuity and reliability of air treatment while ensuring the air treatment effect and efficiency.

[0039] like Figure 1 As shown, the end of the first air inlet pipe 121 away from the first three-way valve has a trumpet expansion section 1211, and the area surrounded by the trumpet expansion section 1211 forms a placement area. This arrangement is conducive to increasing the suction area and suction effect of the gas.

[0040] like Figure 1 As shown, the top of the dust removal box 21 has a cleaning opening 211, and the dust removal mechanism 20 also includes a sealing cover plate 22 detachably arranged at the cleaning opening 211, a frame frame 23 vertically arranged in the dust removal box 21, a partitioning mesh plate 24 embedded in the frame frame 23, and a filter frame 25 arranged on the side of the partitioning mesh plate 24 close to the air intake mechanism 10, the filter frame 25 is embedded with a filter, the frame frame 23 is fixedly arranged below the sealing cover plate 22 and the plane of the frame frame 23 is perpendicular to the horizontal direction of the air intake mechanism 10 toward the dust removal mechanism 20, and the filter frame 25 is located at the bottom area of ​​the dust removal box 21.

[0041] In this embodiment, the frame 23 and the embedded partition mesh plate 24 divide the cavity of the dust removal box 21 into two parts, one part is the air inlet side, and the other part is the air outlet side. The first air outlet pipe 122 and the second air outlet pipe 123 are both connected to the air inlet side, and the first transfer pipe 61 is connected to the top of the air outlet side. The partition mesh plate 24 can be used to block dust particles entering with the air on the air inlet side to prevent them from continuing to flow into subsequent mechanisms such as the deodorization mechanism 30. Furthermore, the shape of the filter frame 25 is adapted to the inner wall of the cavity on the air inlet side, and the filter frame 25 arranged below the partition mesh plate 24 can be used to receive dust particles blocked inside the air inlet side. Furthermore, when cleaning the inside of the dust box 21, the operator can remove the sealing cover 22 and clean the inside of the dust box 21 from the cleaning opening 211, and the frame frame 23 will remove the partition mesh plate 24 and the filter frame 25 together with the sealing cover plate 22, thereby realizing the centralized discharge of dust particles carried on the filter frame 25 and the partition mesh plate 24, facilitating the cleaning and replacement of the dust box 21 and the dust removal medium, and extending the overall service life of the dust removal mechanism 20.

[0042] In this embodiment, the dust removal medium is water. As a dust removal medium, water can not only effectively remove particulate matter in the air, but also increase air humidity, and is suitable for air purification in dry environments. The dust removal mechanism 20 also includes at least two water level sensors 26. The second air outlet 123 and the dust removal box 21 are connected to form a second air outlet, and the first air outlet 122 and the dust removal box 21 are connected to form a first air outlet. The first three-way valve and the first air outlet are located at the same height; in the height direction of the dust removal box 21, the area between the first air outlet and the second air outlet forms a safe water level area, and the water level in the dust removal box 21 is maintained in the safe water level area. In this way, the water level is ensured to be within a safe range through the design of the water level sensor, avoiding equipment failure caused by too high a water level, or problems of too low a water level affecting the purification effect, thereby improving the safety and reliability of the device. It can be understood that the water in the dust removal box 21 can be partially filled into the first air outlet pipe 122. By limiting the water level, the height of the water filled into the first air outlet pipe 122 is located below the first three-way valve, thereby avoiding the situation where water is filled into the first air inlet pipe 121 and the second air outlet pipe 123. Preferably, when the first air inlet pipe 121 is connected to the first air outlet pipe 122 and air is taken in, the water in the first air outlet pipe 122 can be pressed back into the dust removal box 21.

[0043] like Figure 2As shown, the deodorizing mechanism 30 includes a deodorizing tank 31, a first sealed drawer box 32, a first mesh plate 33, a titanium dioxide layer 34 and a coconut shell activated carbon layer 35. The side wall of the deodorizing tank 31 has a first drawer opening. The first sealed drawer box 32 is drawable in the deodorizing tank 31 from the first drawer opening. The outer peripheral shape of the portion of the first sealed drawer box 32 extending into the cavity of the deodorizing tank 31 is adapted to the shape of the inner wall of the cavity of the deodorizing tank 31. The first sealed drawer box 32 does not extend into the cavity of the deodorizing tank 31. The shape of part of the body is adapted to and blocks the first draw-out opening, and a first mesh plate 33 is provided on the upper and lower sides of the part of the first sealed draw-out box 32 extending into the cavity of the deodorizing tank 31. The titanium dioxide layer 34 and the coconut shell activated carbon layer 35 are stacked up and down in the area surrounded by the two first mesh plates 33 and the first sealed draw-out box 32. The gas inlet and gas outlet of the deodorizing tank 31 are located on the side of the titanium dioxide layer 34 and the coconut shell activated carbon layer 35 that are away from each other.

[0044] In this embodiment, the combined adsorption of the titanium dioxide layer 34 and the coconut shell activated carbon layer 35 can not only effectively remove various harmful gases and odors in the air, but also further decompose harmful substances under light conditions to achieve a deep purification effect. The first sealed pull-out box 32, the first mesh plate 33, the titanium dioxide layer 34 and the coconut shell activated carbon layer 35 in this embodiment are integrally arranged and can be pulled out and installed in the deodorizing tank 31, which is convenient for operators to perform overall maintenance, replacement and other operations, and improves the convenience of maintenance. It can be understood that the deodorizing material layer is not limited to the titanium dioxide layer 34 and the coconut shell activated carbon layer 35 provided in this embodiment, and can be adaptively replaced according to actual conditions. Combined with the pull-out replacement of the titanium dioxide layer 34 and the coconut shell activated carbon layer 35, it is beneficial to improve the applicability of the deodorizing mechanism 30.

[0045] like Figure 3As shown, the processing mechanism 50 includes a negative ionization mechanism 51 and an atomizing air outlet mechanism 52 which are interconnected. The outlet of the second pipeline 42 is connected to the negative ionization mechanism 51 in an on-off manner.

[0051] In summary, the present invention provides a dust removal and deodorization device, which detects air quality by means of a first electronic nose sensor 11 disposed in a trumpet expansion section 1211 of a first air inlet pipe 121. When the air needs to be dusted or deodorized, the first fan 14 starts and draws air inward. When the first electronic nose sensor 11 and the air inlet detection submodule 711 determine that the air needs to be dusted and deodorized, the switching control submodule 721 controls the first switching element 13 (first switching valve) so that the first air inlet pipe 121 is connected to the first air outlet pipe 122. The air is filled into the water in the dust removal box 21 and the dust is removed. The gas after dust removal passes through the partition mesh plate 24 and enters the deodorizing tank 31 from the first transfer pipe 61 on the top of the dust removal box 21. When the air intake detection submodule 711 determines that only the air needs to be deodorized, the switching control submodule 721 controls the first switching element 13 (first switching valve) to connect the first air inlet pipe 121 with the second air outlet pipe 123, and the air enters the vacant area of ​​the deodorizing tank 31 and directly enters the deodorizing tank 31 from the first transfer pipe 61 on the top of the dust removal box 21. The air passing through the dust removal mechanism 20 enters from the top of the deodorizing tank 31 through the third transfer tube 63 and passes downward through the titanium dioxide layer 34 and the coconut shell activated carbon layer 35 in sequence for deodorization. The deodorized air is discharged from the top of the deodorizing tank 31 into the detection box 45, and the air quality is detected again by the second electronic nose sensor 41 arranged in the detection box 45. When the second electronic nose sensor 41 and the processing detection submodule 712 determine that the air needs to be processed again (not up to standard), the switching control submodule 721 controls the second switching member 43 (second switching valve) to connect the second air inlet pipe 421 with the fourth air outlet pipe 423, and the fourth air outlet pipe 423 is connected to the first air inlet pipe 121, so that the air passes through the deodorizing tank again. The dust mechanism 20 and the deodorization mechanism 30, when the second electronic nose sensor 41 and the processing detection submodule 712 determine that the air does not need to be processed again (up to standard), the switching control submodule 721 controls the second switching member 43 (second switching valve) so that the second air inlet pipe 421 is connected to the third air outlet pipe 422 and the air is discharged into the negative ion tank 511 of the processing mechanism 50, and the air moves from bottom to top and passes through the PP resin melt spinning layer 514 and the tourmaline particle layer 515 in sequence to achieve negative ionization, and the negative ionized air is discharged from the top of the negative ion tank 511 and enters the atomization tank 521 through the second transfer pipe 62, and is quickly atomized and discharged under the action of the atomization sheet 522 and the fan 523. In this process, when the water inlet submodule 722 and the water level sensor 26 detect that the water level in the dust removal box 21 is not up to standard, the operator replenishes water into the dust removal box 21 through the external pipeline.
