Description

M331980 VIII. New description: [New technical field] This creation involves the technical field of the device, especially the water inlet and outlet structure of the filter cartridge which is easy to assemble and has good leakage prevention effect. , 衣衣 [Previous technical standard] Taiwan Patent No. M281697 shows a structure of a conventional filter cartridge inlet and outlet. When the pipe joint screw is disposed in the inlet and outlet holes, only one of the front end of the ring is urged to the cone in the inlet and outlet holes to achieve the purpose of stopping leakage. However, the 〇-shaped ring is susceptible to wear of the threads in the inlet and outlet holes when the pipe joint is screwed, so that the leakage prevention effect is not good, and the 〇-type ring system is in contact with water for a long time. Its aging condition is exacerbated, and its service life is shortened. Taiwan Patent Publication Nos. M265106, 428492, 428491, and 268559 show another conventional filter cartridge inlet and outlet structure. The pipe joint is mainly a sin that is protruded from the side of the shackle or an additional fixing member that slaps it on the filter room. The distal pipe joint only has two 〇-shaped rings for preventing water leakage. However, since both of the 〇-shaped rings are pressed against the holes J of the inlet and outlet holes, the effect of stopping the leakage is poor. Moreover, the latch or the fixing member has only the effect of positioning, and the tube joint can only be fixed at a predetermined position, so that the official joint cannot produce a pressing effect on the inlet and outlet holes. Therefore, it is easy to cause water leakage due to manufacturing tolerances or errors in installation. 5 M331980 [New content] The main purpose of this creation is to provide a structure that is easy to assemble and that stops the water in and out of the filter cartridge. Its structure consists of a filter cartridge and two pipe joints. The filter cartridge has a water inlet hole and a water outlet hole. The inlet and outlet holes are penetrated into the interior of the filter cartridge, and each has a larger inner diameter engagement section at the open end. The engaging section has a first tapered surface, two second tapered surfaces and a threaded portion. The first tapered surface is located at an opening end edge of the inlet and outlet holes. The second tapered surface is located at an end away from the opening of the inlet and outlet holes: the threaded portion is located between the first tapered surface and the second tapered surface. The two pipe joints are incorporated into the pure section of the inlet, & water hole. Each of the pipe joints includes a threaded section, a projection, a first 0-ring and a ^2 ring. The shank can be screwed to the threaded portion of the engaging section. The end of the threaded section has a chamfer, and there is a groove near the chamfer. The projection is located at the other end of the threaded section and has an external control = greater than the threaded section. The first 〇-type ring system is sleeved on the thread segment and is near the projection. The second 〇-shaped ring system is embedded in the groove.

Thus, when the thread segment is screwed into the threaded portion of the (four) engaging section, the ΐ-two is pressed by the projection to urge the first-cone surface, and the one of the persons presses the second tapered surface. By means of the threaded thread, the assembly of the pipe joint can be made simpler and more convenient, and U is forced, μ improves the manufacturing or assembly error caused by :::, the first 0-ring is forced to the first - The tapered surface and the second!% tightening the second tapered surface are further provided by a tightly deformed connection: a better leak-stopping effect. In particular, it is the 4th gossip. The Haidi-0 type ring is forced to the 6th M331980. The tapered surface does not come into contact with the water in the pipeline, so it is more achievable and the service life is increased. [Embodiment] The first and second diagrams of the brothers show that the water inlet and outlet structure of the filter cartridge of the present invention includes - filter "1" and two tube joints 2. The filter cartridge i includes a cylinder 10, a cartridge body and a filter element 12. The cover body u is attached to the cylinder body 10 and has a water inlet hole 3 and a water outlet hole 14. The two pipe joints 2 are respectively coupled to the water inlet hole 13 and the water outlet hole. The second figure shows that the water inlet hole 13 and the water outlet hole 14 of the cover body U are connected to the inside of the cylinder body 10, and each has a larger inner diameter engagement section 15 at the open end. The filter element 12 is disposed in the cylindrical body 1 , and the water that has entered through the water inlet hole 13 is filtered by the filter element 12 and then discharged through the water outlet hole 14 . The two pipe joints 2 are respectively coupled to the water inlet hole 13 and the joint portion 15 of the water outlet hole 14. In the present embodiment, the joint portion 15 of the water inlet hole 13 and the water outlet hole on both sides of the cover body n is the same as the joint structure of the two pipe joints 2, and the lower portion is the joint portion 15 and the pipe of the water inlet hole 13 The fourth structure of the joint structure of the joint 2 shows the joint structure of the joint portion 15 of the water inlet hole 13 and the pipe joint 2, wherein the joint portion 15 has a first tapered surface 15〇 and a second tapered surface. 151 and threaded portion 152. The first tapered surface 151 is located at the open end edge of the water inlet hole 3. The second tapered surface 151 is located at one end of the opening away from the water inlet hole 13 7 M331980. The threaded portion 152 is located between the first tapered surface 15〇 and the second tapered surface 151.

The pipe joint 2 includes a threaded section 20, a projection 21, a first 0-ring 22 and a second 〇-shaped ring 23. The threaded portion 20 is screwed into the threaded portion 152 of the engaging portion 15 and has a chamfer 24 at one end of the threaded portion 20, and has a groove 25° near the chamfer 24 The outlet portion 21 is located at the other end of the threaded section 20, and has an outer diameter greater than the threaded section 2〇 and is polygonal (as shown in the first figure). The first 0-ring 22 is sleeved on the threaded section 2A and adjacent to the projection 21. The second 〇-shaped ring 23 is embedded in the groove 25. It can be seen in the fourth and fifth figures that when the threaded section 20 of the pipe joint 2 is screwed into the threaded portion of the engaging section, the first 〇-shaped ring 22 is pressed by the protruding portion 21 The first tapered surface 15 is pressed, and the second 0-ring 2 3 is pressed against the second tapered surface 151. In the present embodiment, the pipe joint 2 has a connecting portion 26 with respect to the side of the threaded portion 2, and the connecting portion 26 has an external thread for the socket to be screwed to connect the material. The Wei junction 26 is perpendicular to the screw & segment 20 and may also be perpendicular to the thread segment 2〇. ^ The outer tubular joint 2 may not be provided with the connecting portion 26, but an inner and: a sleeve of the piece is embedded in the hole of the pipe joint 2 to utilize the pipe wall of the blade #二一管件, that is, the pipe fitting The connection is fixed to the (four) joint 2; the creation of the joint can be made simple and convenient by the cooperation of the threaded portion 152 of the joint portion 15 of the threaded section 2 of the joint 2. U is more effective and tighter. 8 M331980 Improves the impact of manufacturing or assembly errors. In addition, 'the first 〇-shaped ring 22 is pressed against the first-cone surface} 5 〇, and when the second 〇-shaped ring 23 is pressed against the second tapered surface 150, the first 〇垔裒 22 and the first 〇 type The ring 23 can be made to have a large contact area by the deformation at the time of pressing, thereby providing a better leak-stopping effect. In particular, the first 〇-shaped ring 22 is pressed against the first tapered surface 15

= contact with the water of the pipe towel's, so it can reduce the aging situation and increase the life of the use. It is enough to teach that you can get the information from the above examples and understand that the creation is indeed industrially useful. The same technology, so this creation is novel. ^No technology similar to this creation. So this creation meets the new patent requirements, Mai Yi.
