As shown in fig. 1 and 6, the skirting line mechanism 15 of the present invention has a length of 1 meter along the basement, which facilitates the installation of the skirting line mechanism 15 at the basement of the wall surface at uniform intervals.

The skirting line A1 and the skirting line B16 are made of PVC materials, so that the weight of the skirting line A1 and the weight of the skirting line B16 are effectively reduced, and the skirting line A1 or the skirting line B16 can be stably installed on the fixing piece mechanism 3 for a long time without falling off; in addition, in the installation process, the two clamping plates 2 on the skirting line a1 or the skirting line B16 made of PVC material can be deformed properly to clamp the fixing member, so that the skirting line a1 or the skirting line B16 installed on the fixing member mechanism 3 is not easy to fall off.

The working process of the invention is as follows: in an initial state, the lower section part of the swinging plate 7 in the fixing mechanism 3 is parallel to and closely attached to the lower section part of the P-type support 4, the sliding block 9 in the fixing mechanism 3 has a certain stroke, the nut part of the inner hexagon bolt 11 is positioned in the counter bore 5, and the positioning ring is closely attached to the inner wall of the P-type support 4; the four support springs 42 actually support the two pressure plates 45, and the two pressure plates 45 are spaced apart from the piezoelectric sensors 41 on the same side.

The mounting and fixing process of the fixing part mechanism 3 is as follows: as shown in fig. 2, when the floor tiles 14 are laid on the indoor floor, gaps with a certain distance are reserved between the floor tiles 14 and the wall surface for installing the fixing device 3, and the width of the gap between the floor tile 14 and the wall surface is slightly larger than the overlapping thickness of the lower ends of the P-type supports 4 and the lower ends of the swing plates 7 in the fixing device 3; the lower end of the P-shaped support 4 and the lower end of the swinging plate 7 in the fixing part mechanism 3 are simultaneously inserted into a gap between the wall surface and the floor tile 14, and the inner hexagon bolt 11 on the fixing part mechanism 3 is rotated by a matched tool, so that the inner hexagon bolt 11 drives the sliding block 9 to move along the direction vertical to the wall surface; the slide block 9 drives the swing plate 7 to swing around the swing pin 8, and the bent part at the upper end of the swing plate 7 is stretched and deformed; the lower end of the swinging plate 7 is separated from the lower end of the P-shaped support 4 and moves towards the side surface of the floor tile 14 and reaches the side surface of the floor tile 14; the lower end of the swinging plate 7 and the lower end of the P-shaped support 4 are respectively outwards supported towards two sides under the swinging of the lower end of the swinging plate 7, so that the fixing frame mechanism is tightly attached to the wall surface and is fixed at the position of a wall foot; the hexagon socket head cap screw 11 continues to be rotated, the lower end of the swinging plate 7 continues to swing and deforms to a certain degree, the acting force of the lower end of the swinging plate 7 and the lower end of the P-type support 4 outwards supporting towards two sides is increased, so that the fixing part mechanism 3 is more stably fixed at the position of the basement of the wall in a clamping mode in the ground gap, and the installation of the fixing part mechanism 3 to the basement of the wall is finished.

The procedure for installing the skirting line A1 and the skirting line mechanism 15 on the fixing member mechanism 3 is as follows: as shown in fig. 1 and 2, two ends of a skirting line a1 or a skirting line B16 are respectively buckled on two spaced fixing mechanisms 3, and two clamping plates 2 vertically distributed on the back of the skirting line a1 clamp the upper end portions of P-type supports 4 in the fixing mechanisms 3, or two clamping plates 2 vertically distributed at two ends of the back of the skirting line B16 clamp the upper end portions of the P-type supports 4 in the fixing mechanisms 3 on the same side; pressing the skirting line A1 or the skirting line mechanism 15 against the wall surface to make the back of the skirting line A1 or the skirting line B16 of the skirting line mechanism 15 tightly contact with the wall surface of the wall, and the lower end surface of the skirting line A1 or the skirting line B16 of the skirting line mechanism 15 tightly contact with the surface of the floor tile 14.

The air purification process of the skirting line mechanism 15 is as follows:

if the skirting line mechanism 15 is provided with the fan module A23, the control system controls the electric drive module A35 to operate, and the output shaft of the electric drive module A35 drives the rotating shaft 33 to rotate through the coupler 34; the rotating shaft 33 drives the cylinder A31 to rotate, and the cylinder A31 drives the blades 32 arranged on the cylinder A31 to rotate; the blades 32 positioned in the range of the cambered surface B27 are in a stretched state and rotate along with the cylinder A31 around the rotating shaft 33 from bottom to top, and the blades 32 in the stretched state effectively convey air entering the rotating groove A25 from the air inlet groove A28 to the air outlet groove A29 from bottom to top; the blades 32 in the range of the cambered surface A26 rotate from top to bottom along the cylinder A31 around the rotating shaft 33 and interact with the cambered surface A26, the blades 32 interacting with the cambered surface A26 are bent and deformed in the opposite direction, and the air quantity taken away from the air outlet groove A29 is reduced, so that the fan module A23 can effectively convey the air entering from the air inlet 20 to the air outlet groove A29 from bottom to top and reach the dust collection cotton 44 through the upper air outlet 18.

If a fan module B46 is installed in the skirting mechanism 15, the control system will control the operation of the electric drive module B66, and the output shaft of the electric drive module B66 will drive the cylinder B54 to rotate about the axis A57 and the axis B58 through the gear A65, the gear B64 and the shaft sleeve 56; the cylinder B54 drives the two circular rings 60 to rotate relative to the eccentric ring 59 through a plurality of angle plates 62 hinged with the inner wall of the cylinder B and a plurality of connecting rods 61 hinged with the bent parts of the angle plates 62; since the circle center of the circular ring 60 deviates and returns periodically and with a fixed amplitude relative to the circle center of the cylinder in the rotating process, so that the periodic separation and return can occur between one point on the inner wall of the cylinder B54 and the opposite point on the corresponding circular ring 60, the single angle plate 62 can swing around the corresponding shaft C63 along with the rotation of the cylinder B54 under the driving of the corresponding connecting rod 61 hinged with the single angle plate 62, and the swinging end of the angle plate 62 can periodically enter and exit the corresponding swinging groove 55 on the cylindrical surface of the cylinder B54. When one end of the angle plate 62 swings out of the swing groove 55 on the cylinder B54 from inside to outside around the shaft C63, a substantial fan blade 32 is formed on the outer cylindrical surface of the cylinder B54, one end of the angle plate 62 swinging out of the swing groove 55 is just positioned in the range of the arc surface B27 of the rotating groove B48, the angle plate 62 swinging out of the swing groove 55 at one end rotates in the range of the arc surface B27 from bottom to top along the central axis of the shaft A57 or the shaft B58 of the cylinder B54, and air entering the rotating groove B48 from the air inlet groove B52 is conveyed to the air outlet groove C51. When one end of the angle plate 62 swings back into the swing groove 55 on the cylinder B54 from outside to inside around the shaft C63 and continues to enter the cylinder B54, the fan blades 32 formed previously on the outer cylindrical surface of the cylinder B54 disappear, at this time, the angle plate 62 swinging into the swing groove 55 or the cylinder B54 is positioned in the range of the arc surface A26 on the rotating groove B48 at the outer cylindrical surface of the cylinder B54, and the angle plate 62 swinging into the swing groove 55 or the cylinder B54 rotates along with the cylinder B54 from top to bottom around the central axis of the shaft A57 or the shaft B58 in the range of the arc surface A26, so that the reverse conveying of the air positioned at the air outlet groove B37 to the air inlet groove B52 is minimized, and the efficiency of the fan module B46 for conveying the air to the dust collection cotton 44 structure is improved.

When the air is conveyed upwards from bottom to top by the fan module A23 or the fan module B46, the air flows and gathers upwards by the dust absorption cotton 44 arranged at the air outlet groove B37 on the guide plate A36 under the guide of the guide plate A36, and the air is filtered by the dust absorption cotton 44 and then is guided by the two guide plates B38 to quickly reach the indoor through the grating grooves 22 on the top cover 21, so that the circulation and reciprocation purification of the indoor air is realized.

When the dust adsorbed on the dust absorption cotton 44 reaches a certain amount, the sum of the weights of the pressure plate 45, the frame B43 and the dust absorption cotton 44 presses the four supporting springs 42 to deform, the pressure plate 45, the frame B43 and the dust absorption cotton 44 integrally move downwards for a certain distance and generate pressure on the two piezoelectric sensors 41 arranged at the upper end of the frame A39, and the piezoelectric sensors 41 generate electric signals and trigger an alarm circuit consisting of a triode, a buzzer and a light-emitting diode, so that the buzzer sends out alarm sound to prompt the timely replacement of the dust absorption cotton 44. When the dust absorption cotton 44 is replaced, the part of the top cover 21, which is positioned at the finger groove 19, is acted upwards by a finger, so that the top cover 21 swings around a fixed shaft and is opened; taking out the dust absorption cotton 44 structure and slightly putting the new dust absorption cotton 44 structure into the frame A39, so that the four supporting springs 42 form actual support for the dust absorption cotton 44 structure, and the two pressing plates 45 are respectively away from the piezoelectric sensor 41 on the same side by a certain gap; and then the top cover 21 is covered.

If the skirting line A1 or the skirting line mechanism 15 is damaged, the skirting line A1 or the skirting line mechanism 15 can be detached and replaced independently.

In conclusion, the beneficial effects of the invention are as follows: the fixing part mechanism 3 is fixed in a reserved gap between the floor tile 14 and a basement in a mode that the inner hexagon bolt 11 is in threaded fit with the sliding block 9 to drive the swinging plate 7 to swing, and the fixing part fixed in the ground gap is not easy to loosen due to the self-locking property of the threaded fit of the sliding block 9 and the inner hexagon bolt 11; the skirting line A1 and the skirting line mechanism 15 can be installed by buckling the fixing piece; compared with the traditional skirting line installation mode, the skirting line installation mode cannot damage the wall surface, and the skirting line is not easy to fall off; when the skirting line A1 or the skirting line mechanism 15 is damaged after long-time use, the damaged skirting line can be replaced without damaging the wall surface and the skirting line, and the maintenance cost and the maintenance efficiency are low.

The skirting line mechanism 15 has the function of purifying indoor air, so that the skirting line mechanism 15 which plays the function of an air purifier does not occupy any indoor space while meeting the requirement of indoor decoration and beauty; compared with the traditional air purifier, the air purifier has smaller volume, does not influence the activity space of people, realizes the air purification function and simultaneously increases the indoor aesthetic property.
