DETAILED DESCRIPTION

[0027] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific implementation manners of the utility model, and does not strictly limit the protection scope specifically requested by the utility model.

[0028] As Figures 1-5 shown, a double-layer filter cotton device of a smoke purifier, the inside of a purification box 1 is provided with a purification device, which can purify the smoke filtered through a filter box 2, the bottom of the purification box 1 is provided with an air outlet, which can discharge the purified air, a support block 15 fixedly connected between the filter box 2 and the purification box 1 is used for supporting the stability of the filter box 2, and the gap between the purification box 1 and the filter box 2 can enable the storage box 16 to slide and clean the collected smoke dust.

[0029] Referring to the drawings Figure 3, the smoke enters the inner cavity of the filter box 2 through the air inlet 3, and is sucked into the filter box 2 after the exhaust fan inside the filter box 2 is started. The exhaust fan is located directly above the ventilation pipe at the bottom of the filter box 2 and communicates with the exhaust fan. The exhaust fan sucks the smoke and transports it to the inner cavity of the purification box 1 through the ventilation pipe.

[0030] Referring to the drawings Figure 3 and the drawings Figure 4 The baffle 5 is provided with two, which are fixedly connected with the two ends of the partition plate 4 respectively, and the baffle 5 is located at the edge of the air inlet 3, and the baffle 5 forms a flue, which can guide the smoke to pass through

[0031] Further, the partition plate 4 in the inner cavity of the filter box 2 forms an annular space, and the exhaust fan is located inside the annular space. The annular flue increases the contact area of the exhaust fan and the smoke, significantly improves the suction efficiency of the smoke, and when the exhaust fan rotates, the smoke is sucked into the inner cavity of the filter box 2 and rotates in a vortex along the rotation direction, reducing the possibility of smoke escaping and ensuring that the smoke is fully sucked in.

[0032] According to the above structure, the surface of the filter screen 11 is corrugated and curled, effectively increasing the contact area with the smoke, so that the smoke can be more fully filtered. The two filter screens 11 are arranged between the two baffles 5, and the filter screen 11 located at the front side is placed in an inclined manner. Compared with the upright filter screen 11, the inclined filter screen 11 can form a larger contact area with the smoke, not only significantly improving the filtering effect so that the harmful substances in the smoke are greatly reduced after filtering, but also prolonging the service life, reducing the replacement frequency, and reducing the use cost. While improving the use convenience, it is also more economical and environmentally friendly.

[0033] Further, the filter screen 11 located on the front side and in an inclined manner can efficiently intercept large particles of dust in the smoke. During the interception process, the dust will continue to accumulate, and part of the accumulated dust will naturally fall downward due to gravity, and the remaining dust will gradually accumulate at the wave curling part of the filter screen 11. With the passage of time, if the dust accumulates too much, it will inevitably affect the purification effect of the smoke. When this situation occurs, the user only needs to open the cover 13 at the top of the filter box 2 to expose the dismounting opening 12 to the outside, and then enter the inner cavity of the filter box 2 through the dismounting opening 12 and knock the filter screen 11 gently. Through the vibration generated by the knocking, the dust attached to the surface of the filter screen 11 can be easily removed. These fallen dust will fall into the inner cavity of the storage box 16 through the waste port 17 at the bottom of the filter box 2 to complete the collection. On the one hand, the effective interception of large particles of dust by the inclined filter screen 11 can significantly reduce the burden of the subsequent purification link and improve the overall purification efficiency. On the other hand, the ingenious use of knocking vibration to make the dust fall off and collect is simple and convenient, without the need for a complex dismounting process, greatly reducing the difficulty and cost of maintenance. At the same time, collecting the dust in the inner cavity of the storage box 16 avoids secondary pollution of the dust and ensures the cleanliness of the purification environment, prolonging the service life of the purification equipment.

[0034] Further, the filter screen 11 located on the rear side performs secondary filtration on the smoke preliminarily filtered by the front-side filter screen 11, further removing fine impurities in the smoke. The design of the front-side inclined filter screen 11 increases the distance between the two filter screens 11, so that the coarsely filtered smoke can flow more smoothly through this space under the action of the suction force of the exhaust fan, realizing more efficient secondary purification when passing through the rear-side filter screen 11.

[0035] Referring to the drawings Figure 5 The surface of the baffle 5 is provided with two sliding grooves 6, and the clamping groove 7 is also provided with two, and the two ends of the clamping groove 7 are respectively communicated with the sliding grooves 6 on the surface of the corresponding two baffles 5. The two filter screens 11 respectively slide in the inner cavities of the corresponding sliding grooves 6 and finally slide into the clamping groove 7, which can limit the two filter screens 11.

[0036] Further, the top of the filter screen 11 is provided with a recess, which facilitates the user to hold it. When the filter screen 11 needs to be replaced, the user can easily take it through the recessed part at the top, which can effectively avoid the dust accumulated on the surface of the filter screen 11 from staining the hands during the replacement process, reducing the trouble of the user to clean his hands.

[0037] Referring to the drawings Figure 5The fixed block 8 fixedly connected to the surface of the baffle 5 provides support force for the push plate 10, and the limiting groove 9 enables the push plate 10 to rotate, and when rotating, the dust on the surface of the inclined filter screen 11 can be removed; the air generated when the air exhauster inhales can drive the push plate 10 to rotate, thereby automatically cleaning the filter screen 11 and prolonging the service life of the filter screen 11.

[0038] With reference to the drawings Figure 2 The buckle 14 is only used for clamping and fixing with the surface of the filter box 2, and the specific structure is not limited.

[0039] The working principle of the utility model is as follows: after starting the purification box 1, the exhaust fan in the inner cavity of the filter box 2 enters the smoke into the inner cavity of the filter box 2 through the air inlet 3, passes through the two filter screens 11 in the filter box 2, and the gas filtered through the two filter screens 11 enters the inner cavity of the purification box 1 through the ventilation pipe for the last purification.

[0040] When cleaning, the clamping of the buckle 14 and the surface of the filter box 2 is released, the cover plate 13 is pushed, the filter screen 11 is exposed outside, the filter screen 11 is knocked at this time, the sundries intercepted on the surface of the filter screen 11 placed obliquely can be removed, the falling smoke dust falls into the inside of the storage box 16 through the waste port 17, and the push plate 10 can be rotated at the same time, and the push plate 10 can clean the surface of the filter screen 11.

[0041] When replacing, the clamping of the buckle 14 and the surface of the filter box 2 is released, the cover plate 13 is pushed, the filter screen 11 is exposed outside, then the filter screen 11 is taken out and separated according to the track of the sliding chute 6, the disassembly is completed, then the new filter screen 11 is pressed down according to the track of the corresponding sliding chute 6, so that the bottom of the filter screen 11 slides to the inner cavity of the corresponding clamping groove 7, the installation is completed, then the cover plate 13 is covered and the clamping of the buckle 14 and the filter box 2 is completed, and the replacement is completed.

[0042] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
