Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

A ventilation device for a dryer comprises an air outlet arranged on a dryer body, and further comprises a cylinder I1, an annular fixing part 2 and a cylinder II3 which are sequentially arranged, wherein the cylinder I1 is inserted into the air outlet, the fixing part 2 is sleeved on the tail end of the cylinder I1, one end of the cylinder II3 is tightly attached to the back surface of the fixing part 2, and the inner diameter of the cylinder II3 is larger than that of the cylinder I1.

As shown in fig. 1, when there is hot air in the machine body discharged through the air outlet, the hot air is discharged to the outside of the machine body through the cylinder I1 and the cylinder II3, wherein because the inner diameter of the cylinder II3 is larger than the inner diameter of the cylinder I1, when the hot air may condense into water drops on the inner side wall of the cylinder II3 or the parts in the cylinder II3 and drop on the bottom of the cylinder II3 under the influence of gravity, or slide down to the bottom of the cylinder II3 along the inner arc wall of the cylinder II3, because a large height difference exists between the inner bottom wall of the cylinder II3 and the inner bottom end of the cylinder I1 at this time, the liquid at the bottom of the cylinder II3 does not flow back into the cylinder I1 and flow into the machine body, and affects the parts in the machine body, but flows out from the outlet end on the right side of the cylinder II 3.

As shown in figure 1, a strip-shaped notch 6 is arranged at the bottom of the top end of the outer side of the cylinder II3, a cylinder 7 is further arranged in the opening at the right side of the cylinder II3, wherein the bottom of the cylinder 7 is provided with a fixed block 14 positioned in the gap 6, the inner side wall of the cylinder II3 is also provided with a magnetic connecting layer 8 connected with the outer side wall of the cylinder 7, a clamping groove for accommodating the magnetic connecting layer 8 is arranged on the inner side wall of the cylinder II3, filter screens 9 are obliquely arranged at two ends in the cylinder 7, wherein the inclination directions of the two groups of filter screens 9 are opposite, a fan 10 is also arranged in the cylinder 7 between the two groups of filter screens 9, a handle is arranged on the outer side wall of each filter screen 9, wherein the interval between two sets of filter screens 9 tops is greater than the interval between its bottom, all inclines to be provided with the incision at drum 7 both ends simultaneously, wherein parallel arrangement between incision and the filter screen 9 that corresponds.

When the air purifier is used, the fan 10 works to forcibly discharge hot air in the machine body through the cylinder I1 and the cylinder II3 and forcibly input cold airflow outside the machine body into the machine body, so that the purposes of ventilation and heat dissipation in the machine body are achieved, and in the process, air flowing through the cylinder 7 is filtered through the two groups of filter screens 9, so that impurities are prevented from entering the machine body to influence the normal operation of equipment.

When the device is installed, the cylinder 7 is inserted into the cylinder II3, the fixing block 14 slides into the notch 6 and is abutted against the notch, the cylinder 7 can be prevented from moving leftwards or rotating in the cylinder II3, the displacement amplitude of the cylinder 7 in the cylinder II3 is further limited, the magnetic connecting layer 8 is fixedly adsorbed on the outer side wall of the cylinder 7 at the moment, the cylinder 7 is movably fixed at a designated position in the cylinder II3, the cylinder 7 is prevented from sliding out of the cylinder II3 without human intervention, and when the filter screen 9 or the fan 10 needs to be treated, the cylinder 7 only needs to be moved outwards, so that the cylinder 7 is separated from the magnetic connecting layer 8, and the cylinder 7 is further extracted from the cylinder II 3.

And both ends of the inner top of the cylinder 7 are provided with beating mechanisms 11 which are positioned at the outer sides of the corresponding filter screens 9, wherein the beating mechanisms 11 comprise elastic connecting ropes 111 fixed at the tops of the inner side walls of the cylinder 7, beating balls 112 are arranged at the bottom ends of the connecting ropes 111, and meanwhile, beating seats 113 corresponding to the beating balls 112 are arranged on the outer side walls of the filter screens 9.

So can produce suction or thrust to the ball 112 of knocking of different sides when fan 10 during operation, and then make to strike the swing of ball 112 and rock in order to drive connecting rope 111, and the connecting rope 111 that rocks drives to strike and can hit ball 112 and rock the time can produce the striking with knocking seat 113, can vibrate it when striking impact on seat 113 conducts to filter screen 9 this moment, and the filter screen 9 of vibration can make the adhesion shake in its impurity on its surface and fall in order to prevent that it from blockking up filter screen 9 aperture, make need not the frequent manual clearance of workman to filter screen 9.

Simultaneously, the bottom of the cylinder II3 is buckled with an arc-shaped guide plate 4, the lower half side wall of the cylinder II3 close to the fixing part 2 in the opening of the guide plate 4 is of a net-shaped structure 5, condensed liquid in the cylinder II3 in the inner side of the cylinder 7 converges to the bottom of the cylinder II3 and then flows to the guide plate 4 through holes of the net-shaped structure 5 and is discharged, wherein, when the fan 10 works, the generated suction force can drive a small amount of air in the outer side of the machine body to flow into the guide plate 4, and the air flows into the sleeve II3 from the net-shaped structure 5 and is finally extracted by the suction force generated by the fan 10, and at the moment, the small amount of air can further dry the inner side wall of the cylinder II 3.

As shown in figure 1, a ring 12 which is coaxially arranged with a cylinder I1 and is positioned in a cylinder II3 is arranged at one end of the cylinder I1, the inner diameter of the ring 12 is equal to the inner diameter of the cylinder I1, wherein the section of the ring 12 is in a right triangle shape, a straight line is formed between one right-angle side of the ring 12 and the inner side wall of the cylinder I1, liquid dropping after condensation in the cylinder II is prevented from contacting and flowing into the dryer through the right-side opening of the cylinder I1 in a shielding mode of the ring 12, and meanwhile, the inclined surface of the ring is easy to guide the liquid to flow down and is not easy to generate siltation.

As shown in fig. 1, a ring of protection part 13 is arranged in the opening at the other end of the cylinder I1, wherein the section of the protection part 13 is a right triangle, and a straight line is formed between one of the right sides of the protection part 13 and the corresponding end face of the cylinder I1, so that even if liquid drips into the bottom of the inner side wall of the cylinder I1, the liquid is shielded by the protection part 13 and flows back into the cylinder II3, and does not flow into the dryer.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
