Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to the attached

drawings

1 and 2 of the specification, a filter element replacing device comprises an outer filter bottle 1 and an inner filter bottle 2, wherein the inner filter bottle 2 is installed in the outer filter bottle 1, the outer filter bottle 1 is provided with a water inlet 11 and a purified water outlet 12, and preferably, the water inlet and the purified water outlet are both positioned on the same side of the outer filter bottle; the inner filter flask 2 is internally provided with a filter element which is used for filtering water flow entering the inner filter flask so as to generate purified water, and the structure of the filter element is easily known in the prior art and is not repeated; this interior filter flask 2 has inhalant canal 21 and exhalant canal 22, and this inhalant canal 21 is located the bottom setting of this interior filter flask 2, and this exhalant canal 22 then communicates with this water purification delivery port 12, and produced water purification process this exhalant canal 22 after rivers get into the filter core of this interior filter flask and filter to finally flow out in this water purification delivery port 12, and is preferred, and this inhalant canal 21 and exhalant canal 22 opposite direction set up, and this inhalant canal 21 is located the bottom of interior filter flask promptly, and exhalant canal 22 is located the top of this interior filter flask.

Specifically, the water inlet 11 of the outer filter flask 1 and the water inlet channel 21 of the inner filter flask are communicated with each other through the water channel 3, the water channel 3 is located between the outer filter flask 1 and the inner filter flask 2, the water inlet channel 21 at the bottom of the inner filter flask and the water channel 3 are communicated with each other in a sealing mode through the water channel lower joint 4, preferably, the water channel lower joint 4 is provided with a communication port a, an opening of the communication port a is opened upwards, the water channel 3 extends into the communication port a to be communicated with the water channel lower joint 4 in a sealing mode, and the other end of the water channel lower joint 4 is communicated with the water inlet channel 21 in a sealing mode through the sealing ring. The bottom of the outer filter flask 1 is also detachably connected with a bottom cover 13, the bottom cover 13 is in threaded connection with the outer filter flask 1, and the device is connected through the inner filter flask and the outer filter flask, so that the bottom cover is in threaded connection with the outer filter flask without sealing, and the problem of difficulty in dismounting of the filter flask in the prior art due to the fact that the filter flask is in threaded connection and sealing at the same time can be solved; the middle of the bottom cover 13 is further provided with a bump b, preferably, when the bottom cover 13 is screwed into the bottom of the outer filter flask 1, the water channel lower joint 4 is just located at the bump b and contacts with the water channel lower joint, so that the bump just serves as a supporting surface of the water channel lower joint, and the working reliability of the device is further ensured.
