Examples

As shown in fig. 1, a novel new fan, like the prior art, includes a housing 1 and a fan 2, the housing 1 is provided with the fan 2 therein, the fan 2 uses a 2RS-2 type vacuum pump, two ends of the fan 2 are respectively provided with an air inlet pipe 3 and an air outlet pipe 4, the air inlet pipe 3 is detachably connected with a filter element through a first fixture block and a second fixture block. Because the filter core in the new fan needs frequent change, all can wear and tear the spare part of air-supply line department when changing the filter core each time through prior art's structure, though the filter core is changed swiftly, can wear and tear spare part such as air-supply line many times in the change process, cause the damage of current equipment at last, and the filtration of single filter core makes the air that finally gets into through the air-supply line still remain harmful gas, can't obtain high-quality air promptly. So this application is to these problems, has carried out new design to the connected mode of air-supply line 3 department filter core and the structure of filter core for other spare parts to new fan do not cause the damage when the filter core is changed conveniently, and can carry out the efficient and filter.

Specifically, the air inlet pipe 3 is divided into two air sections, one air inlet section 31 penetrating through the shell 1 and communicated with the outside air, the other air delivery section 32 connected with the fan 2, and a filter core pipe 5 is arranged between the air inlet section 31 and the air delivery section 32. The filter element tube 5 comprises an internal filter element 51 and an external tube shell 52, the tube shell 52 is cylindrical with openings at two ends, internal threads are arranged at two ends of the tube shell 52, external threads 33 matched with the internal threads are arranged at two ends of the air inlet section 31, the air delivery section 32 and the tube shell 52, and the tube shell 52 and the two air sections of the air inlet tube 3 can be tightly connected through the matching of the internal threads and the external threads 33. Further, the tail ends of the external threads 33 of the air inlet section 31 and the air delivery section 32 far away from the port of the pipe shell 52 are both provided with annular sealing strips to ensure the airtightness of the whole air inlet pipe 3 after the pipe shell 52 is connected with the two air sections, as shown in fig. 5. The sealing strip is made of rubber.

Furthermore, a plurality of equidistant horizontal arc-shaped notches 6 are formed in the front side wall of the pipe shell 52, and the filter element 51 can be taken out from the side wall of the pipe shell 52 or extend into the pipe shell 52 through the notches 6. And the inside of the rear side wall of the pipe shell 52 without the arc-shaped notch 6 is provided with a plurality of horizontal arc-shaped grooves 7 corresponding to the height of the arc-shaped notch 6, so that the filter element 51 can limit the position of the filter element 51 inside the pipe shell 52 after extending into the inside of the pipe shell 52 through the notch 6, and thus the filter element 51 is prevented from shifting in the using process to influence the normal filtration of the air in the air inlet pipe 3, and the filtration degree of the air is improved, as shown in fig. 2.

Further, a plurality of slot covers 8 corresponding to the slots 6 are provided on the left outer wall of the case 52, as shown in fig. 3 to 4. Specifically, the front and rear ports of the notch 6 are respectively provided with a protruding block 9 to be matched and connected with the slot cover 8, the protruding blocks 9 are provided with a threaded hole A91, the slot cover 8 is in an arc shape matched with the shape of the notch 6, and in order to enable the slot cover 8 to completely cover the notch 6, the height of the slot cover 8 is larger than that of the notch 6. The front end and the rear end of the slot cover 8 are provided with threaded holes B matched with the threaded holes A91 on the protruding block 9, so that the slot cover 8 and the slot 6 are fixed through bolts after the filter element 51 is inserted into the tube shell 52. In order to facilitate the user's insertion and removal of the filter cartridge 51 when replacing the filter cartridge 51 inside the cartridge case 52, the filter cartridge 51 is held in place inside the cartridge case 52 with its edge near the slot 6 being partially outside the slot 6, so that the upper and lower ends of the slot cover 8 are provided with sealing blocks 81, respectively, with a recess formed between the sealing blocks 81, so that after the slot cover 8 is fixed to the slot 6, the sealing blocks 81 are located between the outer wall of the cartridge case 52 and the inner wall of the slot cover 8, and the part of the edge of the filter cartridge 51 protruding out of the slot 6 can be placed between the recesses formed by the upper and lower sealing blocks 81 of the slot cover 8, thus ensuring the tightness of the entire cartridge 5. The seal block 81 is made of rubber.

This application is equipped with a plurality of notches 6 on tube 52, and the user can install a plurality of different filter cores 51 according to specific air condition and different demands, for example, when the air is more moist, the user can install simultaneously and have filter core 51 of filtering harmful gas and can absorb the filter core 51 of steam. In the season of poor air condition, can add a plurality of filter cores 51 that can filter gaseous pollutants to reach the high-efficient filtration to the air, in the season of good air condition, can reduce the setting of filter core 51 in tube shell 52, in order to practice thrift filter core 51's use. And the filter element 51 is very convenient to detach and install, because the shell 52 is fixed with the air inlet pipe 3 through the threaded connection, a user can detach and install the filter element 51 by only extending the filter element 51 into the shell 52 through the notch 6 or taking out the filter element 51 from the notch 6. Specifically, the user removes the slot cover 8 on the outer wall of the cartridge 52 to expose the slot 6 on the cartridge 52, and then removes the filter element 51 from the cartridge 52. After replacing the new filter element 51, the filter element 51 is extended into the shell 52 through the notch 6 again, and after the filter element 51 is placed in the groove 7 of the shell 52 for fixing, the groove cover 8 on the outer wall of the shell 52 is fixed through the bolt again, and then the replacement of the whole filter element 51 can be completed. This application simple structure has very strong practicality, has brought very big facility for daily use new fan's user, satisfies different users' filtration demand in different seasons, has improved the drawback of current new fan, has effectively improved the life of new fan internal part.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
