It should be mentioned that the threaded sleeve 3 may be preferably connected to the housing 1 by welding, and the threaded sleeve 3 and the roll shaft 2 are located on the same axis, so that the first sealing portion 4 and the second sealing portion 5 seal between the roll shaft 2 and the threaded sleeve 3, and of course, the adjusting member 6 is screwed with the threaded sleeve 3, so that the adjustment of the adjusting member 6 can be facilitated, and the adjustment of the adjusting member 6 on the threaded sleeve 3 can control the sealing of the second adjusting portion with the roll shaft 2.

In addition, the seal between the first seal portion 4 and the housing 1 can be ensured on the housing 1 where the first seal portion 4 abuts, and the first seal portion 4 and the second seal portion 5 are arranged in the thread bush 3, so that the seal between the first seal portion 4 and the second seal portion 5 can be realized, the tightness between the roll shaft 2 and the housing 1 can be improved, and the phenomena of water leakage and water seepage can be avoided.

Based on the above overall description, in this embodiment, an exemplary structure of a sealing device for a self-cleaning water purifier, as shown in fig. 3, the first sealing part 4 includes a sealing ring 401 abutting against the housing 1, and a supporting ring 402 disposed in the sealing ring 401, the supporting ring 402 being sleeved on the roller shaft 2.

It should be noted that, the two surfaces of the sealing ring 401 are respectively abutted on the inner walls of the shell 1 and the thread bush 3, so that water leakage at the joint of the sealing ring 401 and the shell 1 is avoided, and the second sealing part 5 can be pushed by adjusting the adjusting piece 6 on the thread bush 3, the second sealing part 5 is abutted on the sealing ring 401 and the shell 1, so that the sealing between the sealing ring 401 and the shell 1 is realized, and the effect of the supporting ring 402 can ensure that the sealing ring 401 keeps circular, and the sealing ring 401 and the thread bush 3 are in interference fit, so that deformation of the sealing ring 401 can be avoided by arranging the supporting ring 402 on the inner wall thereof.

Further, as also shown in fig. 3, the seal ring 401 of the present embodiment has a first portion 4011 abutting against the threaded sleeve 3, and a second portion 4012 perpendicular to the first portion 4011 and abutting against the housing 1, the first portion 4011 and the second portion 4012 being provided on the support ring 402 in a conformal manner. Specifically, the first portion 4011 and the second portion 4012 are L-shaped in cross section and fit over the support ring 402, so that the problem of separation of the support ring 402 and the seal ring 401 during installation can be avoided, and of course, the first step is clamped by the side surface of the support ring 402 and the wall of the housing 1, and the second portion 4012 is clamped by the outer ring of the support ring 402 and the inner wall of the threaded sleeve 3, so that the sealing effect is improved.

As a preferred embodiment, as shown in fig. 4 and 5, in the present embodiment, the second seal portion 5 includes a seal 501 provided in a telescopic manner, an outer ring 502 provided on the seal 501, and an inner ring 503 provided inside the outer ring 502 and abutting against the first seal portion 4.

It should be noted that, the outer ring 502 and the inner ring 503 fix one end of the sealing element 501, through the adjustment of the adjusting element 6, the sealing element 501 may be pushed, and the sealing element 501 pushes the inner ring 503 to abut against the supporting ring 402, so as to realize that the sealing ring 401 seals with the housing 1 through the pushing of the supporting ring 402, and certainly, through the adjustment of the adjusting element 6, the expansion and contraction of the sealing element 501 may also be controlled, so as to ensure the sealing element 501 to seal with the roll shaft 2, thereby avoiding the water seepage phenomenon between the sealing element 501 and the roll shaft 2.

As shown in fig. 6 and 7, a stopper 504 for restricting movement of the inner ring 503 is provided on the inner wall of the outer ring 502, and a stopper 505 abutting against the stopper 504 is provided on the outer wall of the inner ring 503. Since the sealing member 501 pushes the inner ring 503 to abut against the supporting ring 402, the stopper 504 of the outer ring 502 abuts against the stopper 505 of the inner ring 503, thereby preventing the outer ring 502 from being separated from the inner ring 503, and preventing the sealing member 501 from being separated.

As shown in fig. 6, the sealing member 501 of the present embodiment preferably has a sealing sleeve 5011 for sealing the roller shaft 2, one end of the sealing sleeve 5011 is covered on the inner ring 503, the other end of the sealing sleeve 5011 is covered with a top ring 5012, and an elastic member 5013 is provided between the top ring 5012 and the inner ring 503. The diameter of the sealing sleeve 5011 gradually increases from one end of the top ring 5012 to one end of the inner ring 503.

Specifically, the sealing sleeve 5011 is in a horn shape, when the top ring 5012 pushes the sealing sleeve 5011 to deform, the sealing sleeve 5011 approaches to the axle center, so that the sealing is realized by abutting against the roll shaft 2, the elastic piece 5013 can adopt a spring, and when the adjusting piece 6 is adjusted to be far away from the shell 1, the elastic force of the spring can push the top ring 5012 to reset, so that the sealing sleeve 5011 deformed to the axle center is ensured to reset.

In order to achieve uniformity of deformation of the seal cartridge 5011, as shown in fig. 7, the top ring 5012 of the present embodiment has a circular ring 5014 which is fitted over the seal cartridge 5011, and a baffle plate 5015 which is provided on the circular ring 5014 and supports the elastic member 5013. A limit ring 5016 is arranged on the seal ring 401 at two sides of the circular ring 5014.

The function of the baffle 5015 is that the supporting elastic member 5013 is used, because the sealing sleeve 5011 is in a horn shape, one end with a large diameter is fixed between the outer ring 502 and the inner ring 503, the end with a small diameter is deformed to the axle center of the end with a large diameter by the forward pushing of the circular ring 5014, and the deformed position is abutted with the roll shaft 2 to form a seal due to the different thickness, so that the sealing sleeve 5011 can adapt to the roll shafts 2 with different diameters, and the sealing effect is ensured.

As shown in fig. 1 and 2, in this embodiment, the adjusting member 6 is provided with a threaded hole 601 to which a screw is connected, and the screw abuts against the threaded sleeve 3.
