Of course, the limiting structure 232 is preferably configured as the bar-shaped body 2321 and the limiting block 2322.
It should be noted that, in practical applications, a person skilled in the art may configure the bar-shaped body 2321 as an elastic rod, or may configure the bar-shaped body 2321 as an elastic plate, or may configure the bar-shaped body 2321 as an elastic sheet, and the like, and such adjustment and change of the specific structural form of the bar-shaped body 2321 do not depart from the principle and scope of the present invention, and are all included in the protection scope of the present invention.

Preferably, as shown in fig. 2 to 5, the limiting block 2322 is provided with an inclined surface 2324, so that the limiting block 2322 can smoothly enter the opening 21 when the blocking member is installed.
Through the arrangement, when the plugging member is installed, when the limiting block 2322 contacts the opening 21, the opening 21 of the filter bottle 2 acts on the inclined surface 2324 on the limiting block 2322, and the limiting block 2322 drives the bar-shaped body 2321 to deform, so that the limiting block 2322 smoothly enters the filter bottle 2 from the opening 21, and the plugging member is convenient to install.
Preferably, as shown in fig. 2 to 5, the limiting block 2322 is configured as a triangular wedge, the inclined side of the triangular wedge forms the inclined surface 2324, and one of the right-angled sides of the triangular wedge forms the abutting plane 2323.
Through the arrangement, when the plugging member is installed, when the inclined surface 2324 of the limiting block 2322 is placed at the opening 21 of the filter bottle 2, the opening 21 of the filter bottle 2 acts on the inclined surface 2324, and the inclined surface 2324 drives the strip-shaped body 2321 to elastically deform, so that the limiting block 2322 smoothly enters the filter bottle 2 from the opening 21; when the filter bottle 2 is taken out of the water channel plate 1, the plug 231 of the blocking member blocks the opening 21, and the abutting plane 2323 on the limit block 2322 abuts against the inner side of the opening 21 of the filter bottle 2 (as shown in fig. 3), so that the blocking member is prevented from being removed from the opening 21.
It should be noted that, in practical applications, the limiting block 2322 is not limited to be configured as the triangular wedge, for example, the limiting block 2322 may be configured as a right-angled trapezoidal wedge, a sloping side of the right-angled trapezoid forms the inclined surface 2324, a bottom side of the right-angled trapezoidal wedge forms the abutting surface 2323, and so on, and such adjustment and change of the specific shape of the limiting block 2322 are not departing from the principle and scope of the present invention, and are all included in the protection scope of the present invention.
It should also be noted that, in practical applications, a person skilled in the art may set the number of the limiting structures 232 to two, or may set the number of the limiting structures 232 to multiple, etc., and such adjustment and change to the specific set number of the limiting structures 232 without departing from the principle and scope of the present invention should be included in the protection scope of the present invention.
Preferably, as shown in fig. 2 to 5, the number of the stopper structures 232 is set to two.
It should be noted that, in practical applications, a person skilled in the art may arrange the limiting structures 232 to be distributed along the circumferential direction of the plug 231, or may arrange the limiting structures 232 on two sides of the plug 231, respectively, and so on, and such adjustment and change of the specific arrangement position of the limiting structures 232 without departing from the principle and scope of the present invention should be included in the protection scope of the present invention.
Preferably, as shown in fig. 2 to 5, the two limiting structures 232 are disposed oppositely along the plug 231.
Through the arrangement, when the filter bottle 2 is pulled out of the water channel plate 1 and the plug 231 plugs the opening 21, the two limit structures 232 can respectively abut against two ends of the opening 21 (as shown in fig. 4), so that the two sides of the plug 231 are stressed uniformly, and the plug 231 is prevented from being inclined due to uneven stress, and the plugging effect is prevented from being influenced.
The process of mounting and dismounting the filter device of the present invention will be described in detail with reference to fig. 1, 2, 3 and 4.
As shown in fig. 1 and 2, when the plugging member needs to be installed in the filter bottle 2, the inclined surface 2324 of the limit block 2322 abuts against the opening 21 of the filter bottle 2, the plug 231 is pressed towards the direction of the filter bottle 2, the opening 21 of the filter bottle 2 acts on the inclined surface 2324 to deform the strip-shaped body 2321, and the two limit blocks 2322 move towards the direction of approaching each other until the plugging member moves into the filter bottle 2, and the inner side of the plugging member contacts the spring 25, so that the plugging member is installed in the filter bottle 2.
When the water purifier is normally used, the opening 21 of the filter bottle 2 is aligned with the water inlet component 11 on the water path board 1, the water inlet component 11 is inserted into the filter bottle 2, the water inlet component 11 can introduce water of the faucet into the filter bottle 2, the water entering the filter bottle 2 is filtered by the filter element 22 in the filter bottle 2 and finally discharged from a water outlet (not shown in the figure), and when the water inlet component 11 is inserted into the filter bottle 2, the blocking component is pushed to overcome the elastic force of the spring 25 and move towards the direction of the fixed column 24, so that the plug 231 of the blocking component is separated from the opening 21, and the water purifier is normally used.
Illustratively, as shown in fig. 4, in the case of water and electricity cut-off, when the filter device needs to be taken out, the filter bottle 2 gradually leaves the water passage plate 1, the water inlet member 11 gradually moves out of the filter bottle 2, and the blocking member moves toward the opening 21 under the restoring force of the spring 25 and causes the plug 231 of the blocking member to block the opening 21, so as to prevent the filter bottle 2 from leaking water and improve the user experience.
For example, as shown in fig. 3, in the case of passing water and supplying electricity, when the filtering apparatus needs to be taken out, the filter bottle 2 gradually separates from the water passage plate 1, the water inlet member 11 gradually moves out of the filter bottle 2, the blocking member moves towards the opening 21 under the restoring force of the spring 25 and causes the plug 231 of the blocking member to block the opening 21, meanwhile, because the pressure inside the filter bottle 2 is higher, when the blocking member moves towards the opening 21, the blocking member continues to move towards the direction away from the fixing post 24 under the pressure inside the filter bottle 2, and when the limit block 2322 of the blocking member contacts the inner wall of the filter bottle 2, the abutting plane 2323 on the limit member abuts against the inner wall of the filter bottle 2, thereby preventing the blocking member from falling out of the opening 21 of the filter bottle 2 and avoiding water leakage from the filter bottle 2.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
