The utility model has the advantages that:

the utility model provides a purifier of filter core easy dismouting, include the filter core and be used for installing the installing support of filter core, be equipped with snap ring subassembly and knob subassembly on the installing support, the knob subassembly rotates to be connected on the installing support, the knob subassembly has locking position and unblock position, the knob subassembly is when locking the position, the snap ring subassembly is held tightly the filter core and is fixed on the installing support with the filter core, the knob subassembly is when unblock position, the knob subassembly promotes snap ring subassembly and opens to throw off from the installing support for the filter core, the knob subassembly is through rotatory in order to switch between unblock position and locking position. The technical scheme has the following technical effects:

the utility model discloses a set up the knob subassembly that snap ring subassembly and control ring subassembly that are used for holding the filter core tightly and open or tighten up on the installing support, make the user when the installation filter core, only need vertically place the filter core on the installing support, and rotate the knob to the locking position, snap ring subassembly can hold the filter core tightly in order to fix the filter core on the installing support, accomplish the installation of filter core, when the user need dismantle the filter core, only need rotate the knob subassembly to the unblock position, the knob subassembly promotes snap ring subassembly and throw off with the filter core, then take off the filter core from the installing support can, whole renew cartridge's process, the user only needs to draw and place the filter core and rotate the knob subassembly, need not with the help of the instrument, and is more laborsaving in convenient operation, improve user's use experience.

In above-mentioned purifier of filter core easy dismouting, snap ring subassembly includes two semi-rings, and two semi-rings butt joints are in order to be used for holding tightly the filter core. During the installation, the user only needs stretch into the bottom of filter core in the hollow region that two semi-rings enclose, and two semi-rings carry out spacing on the horizontal direction to the filter core when carrying out axial spacing to the filter core through holding tightly in the both sides of filter core to fix filter core locking on installing support, simple structure and locking are effectual.

The semi-rings include installation end and spacing end, and the installation end of two semi-rings rotates to be connected on the installing support, and knob subassembly is located between the spacing end of two semi-rings to be used for promoting spacing end and be close to or keep away from the filter core. Through locating the knob subassembly between two spacing ends for the less knob subassembly of volume can realize tightening up or opening of two semi-rings simultaneously through rotating, reduces the occupation space of knob subassembly, reduces the volume of purifier promptly.

The knob assembly comprises a rotating shaft and pushing bulges, the rotating shaft penetrates through the mounting support, the pushing bulges are arranged on two sides of the rotating shaft, the knob assembly is rotated to an unlocking position from the locking position, the pushing bulges are rotated together along with the rotating shaft, and therefore the limiting ends are pushed away from two sides of the rotating shaft. When the knob assembly is in a locking position, the limiting ends of the two half rings are close to the knob assembly to tightly hold the filter element, the distance between the two limiting ends is the shortest, and each limiting end is simultaneously abutted against the rotating shaft and the two pushing bulges; when the knob assembly rotates from the locking position to the unlocking position, the two pushing protrusions rotate along with the rotating shaft to respectively push the limiting ends of the two half rings towards two sides, so that the two limiting ends move towards the direction away from the rotating shaft, and when the knob assembly is located at the unlocking position, the two half rings are separated from the filter core to separate the filter core from the mounting support. Through set up the promotion arch in the pivot for promote the arch and can open two semi-rings or avoid two semi-rings inwards tightening up when rotating along with the pivot, realize snap ring assembly's locking or throw off, simple structure, simple to operate while simple to operate.

The limiting end is provided with an inward sunken guide curved surface, and the pushing bulge pushes the semi-ring through the guide curved surface. When knob subassembly was in locking position, the laminating of direction curved surface was on the lateral wall of pivot to make the spacing end of two semi-rings be close to as far as in order to hold the filter core tightly, when knob subassembly rotated to the unblock position by locking position, promote protruding sliding along the direction curved surface, in order to promote the semi-ring through the direction curved surface and keep away from the pivot, the direction curved surface plays the guide effect to promoting the arch, so that the user is more smooth and easy when rotating knob subassembly, and the operation is more laborsaving, improves user's operation experience.

The mounting bracket is provided with a through hole for penetrating through the rotating shaft, the two ends of the rotating shaft are respectively provided with a buckle and a knob, and the buckle and the knob are respectively abutted against the mounting bracket at the two ends of the through hole to limit the rotating shaft. Through carrying out spacing in the vertical direction to the countershaft, guarantee that knob subassembly stable installation is on the collar to drive the snap ring subassembly and open or tighten up, guarantee that knob subassembly's lower part is in the below of bottom plate all the time for the user to operate when being convenient for install and dismantle, guarantee the stability of knob subassembly work.

Still be equipped with the elasticity piece that resets on the installing support, the elasticity piece that resets offsets with the semi-ring and embraces the filter core in order to promote the semi-ring tightly, and the elasticity piece that resets is used for promoting the semi-ring automatically and embraces the filter core tightly for user's operation is convenient laborsaving more, guarantees the effect of clasping of snap ring subassembly to the filter core tightly, prevents that snap ring subassembly and semi-ring from freely breaking away from.

Be equipped with the holding tank towards the installing support on the semi-ring, be equipped with the limit baffle who stretches into in the holding tank on the installing support, elasticity resets the spring in the piece for locating the holding tank, and the both ends of spring offset with the inner wall and the limit baffle of holding tank respectively. When the knob subassembly promoted the semi-ring and open, the inner wall and the limit baffle coextrusion spring of holding tank, when the knob no longer promoted the semi-ring, the inner wall of holding tank received the promotion of spring and drove the automatic filter core of hugging closely of semi-ring, and two elasticity reset respectively hide in two semi-rings, when more pleasing to the eye for every semi-ring receives the promotion of single elasticity reset respectively, and the atress is bigger, and it is better to hug closely the effect.

Two semi-rings are connected on the installing support through installation hub rotation, and elasticity piece that resets establishes for the cover at installation epaxial torsional spring, and the both ends of torsional spring offset with two semi-rings respectively, and the torsional spring promotes two semi-rings simultaneously under the spring action to make the spacing end of two semi-rings draw close, realize two semi-rings to hugging closely of filter core, simple structure easily installs.
