Specifically, in the present embodiment, the right end faces of the clamp 21, the filter net 20, and the two side plates 13 are coplanar. During assembly, one end of the fastening member 132 is inserted into the first avoiding groove to prevent the fastening member 132 from propping against the front plate 12, so that gaps are generated between the front plate 12 and the filter screen 20, the clamping member 21 and the two side plates 13, and the filtering effect is reduced.

In another embodiment of the present invention, the fastener 132 includes a head and a shank; the head is fixedly arranged on the end surface of the rod body, and the diameter of the head is larger than that of the rod body; the rod body is provided with a first external thread, and the first external thread is in adaptive connection with the second threaded hole; the head is used to press against the clamp 21. Specifically, the head and the shaft are cylindrical. During the assembly, rotate the head to make it rotatory, thereby it is rotatory to drive the pole body and first external screw thread on it, and then make first external screw thread and second screw hole be connected, finally, the head supports the right-hand member face of pressing holder 21, thereby realizes restriction and fixed to holder 21.

Furthermore, a groove is formed in the end face, far away from the rod body, of the head, so that an assembler can rotate the head conveniently. This recess can be "one" style of calligraphy recess, can be "ten" style of calligraphy recess, also can be hexagon socket head cap groove, so, the assembler just can rotate this head through the instrument, when convenient the equipment, has improved assembly and dismantlement efficiency greatly.

In another embodiment of the present invention, the surfaces of the two sets of clamping pieces 21 close to the filter screen 20 are both provided with first mounting grooves; the top surfaces of the two clamping pieces 21 are respectively provided with at least one mounting through hole, and the mounting through holes are communicated with the first mounting grooves; the bottom surfaces of the two clamping pieces 21 are respectively provided with at least one mounting threaded hole; the mounting threaded hole is coaxially arranged with the mounting through hole and communicated with the first mounting groove; the front end and the rear end of the filter screen 20 are both provided with at least one filter through hole; wherein, use the second bolt to wear to establish in proper order the installation through-hole with filter the through-hole, and with the installation screw hole is connected, thereby realizes filter screen 20 and two sets of the dismantlement of holder 21 is connected.

Specifically, the first mounting groove penetrates through the left end face and the right end face of the clamping piece 21, so that the right end face of the filter screen 20 is coplanar with the right end face of the clamping piece 21, a gap between the filter screen 20 and the front plate 12 is eliminated, and the filtering effect is improved. In this embodiment, all seted up two installation through-holes and two installation screw holes on each holder 21, two installation through-holes and two installation screw holes respectively one-to-one, and equally divide and do not lie in both ends about holder 21. Two filter through holes have all been seted up at filter screen 20's front and back both ends, and are located this filter screen 20's left and right sides both ends respectively, so, are favorable to improving the steadiness of assembly back filter screen 20. During the assembly, insert two holders 21's first mounting groove respectively with filter screen 20 front and back both ends in, use the second bolt to pass mounting hole and filtration through-hole in proper order from the top after that to be connected with the installation screw hole, thereby realize filter screen 20 and two sets of holders 21 can dismantle and be connected.

In another embodiment of the present invention, as shown in fig. 3, the present invention further comprises two sets of fixing members 30 and two sets of first sliding rails 40; the two groups of first sliding rails 40 are respectively and fixedly arranged on the surfaces of the two groups of side plates 13 far away from the filter screen 20; the two groups of fixing pieces 30 are respectively provided with a first sliding groove 31, and the two first sliding rails 40 correspond to the two first sliding grooves 31 one by one and are in sliding fit with each other; two sets of the fixing members 30 are detachably connected to the front and rear ends of the blower unit, respectively.

Specifically, when the air blower is used, the casing 10 and the filter screen 20 are assembled together, the two sets of fixing pieces 30 are installed at the front end and the rear end of the bottom of the air blower unit respectively, then the first slide rails 40 on the two sets of side plates 13 are inserted into the first slide grooves 31 of the two sets of fixing pieces 30 respectively, the casing 10 is pushed, so that the two first slide rails 40 on the casing 10 slide in the two first slide grooves 31 respectively until the casing 10 surrounds the air outlet end of the air blower unit, and finally the casing 10 is fixed on the two sets of fixing pieces 30. The first sliding groove 31 and the first sliding rail 40 are provided to enable an assembling person to move the housing 10 more easily, and the first sliding groove 31 plays a role in supporting, the assembling person can achieve the purpose of moving the housing 10 only by using a pushing force in the horizontal direction, and in addition, a positioning function is also achieved, and the installation accuracy of the housing 10 is improved. So, made things convenient for this whole abluent air cleaner's of exempting from to tear open equipment greatly, and still reduced labour's consumption.

In another embodiment of the present invention, as shown in fig. 2, the top surfaces of the two sets of fixing members 30 are both fixedly provided with mounting blocks 32; the two groups of mounting blocks 32 are positioned on the outer side of the air supply unit; at least two first through holes are formed in the two groups of mounting blocks 32; wherein, use first bolt to wear to establish first through-hole to with blower unit threaded connection, thereby realize the installation piece 32 and the mounting 30 is connected with dismantling of blower unit.

Further, the surface of the mounting block 32 facing away from the filter body is coplanar with the surface of the fixing member 30 facing away from the filter body; the length of the mounting block 32 in the front-rear direction is smaller than the length of the fixing member 30 in the front-rear direction.

Specifically, in the present embodiment, the mounting block 32 is integrally formed with the fixing member 30 by cutting, and the surface of the mounting block 32 facing away from the filter body is coplanar with the surface of the fixing member 30 facing away from the filter body, so as to reduce the processing difficulty and time. The thickness of the mounting block 32 is smaller than that of the fixing member 30 to form a space avoiding position so as to avoid the air outlet end of the blower unit. So design to make the air-out end of air supply unit support and press on mounting 30's top surface, then this moment, mounting 30's top surface then plays the positioning action, that is to say, this moment, connecting thread hole on first through-hole and the air supply unit is coaxial, the suggestion assembly personnel use first bolt to wear to establish first through-hole, and be connected with the connecting thread hole on the air supply unit, improved packaging efficiency and installation accuracy greatly, avoid this whole abluent air cleaner slope of exempting from to tear open to install on the air supply unit.

In another embodiment of the present invention, a first insertion hole is formed in any one set of the fixing member 30, and the first insertion hole penetrates through the front and rear end surfaces of the fixing member 30 and is communicated with the first sliding groove 31 of the fixing member 30; a second jack is arranged on the first slide rail 40 which is closest to the fixing piece 30 provided with the first jack; the second jack is arranged on the surface of the first slide rail 40 far away from the filter screen 20; the first jack and the second jack are sequentially penetrated from the outside by using a plug-in 33, and the plug-in 33 is inserted and matched with the first jack and the second jack so as to fix the shell 10.
