M244961

[Technical field of new type] In particular, it refers to the application of filtering water. This creation is about a lock structure, the lock and structure of the heart. [Prior art] Please refer to the first figure. The filter element for filtering impurities in water generally includes a body 12 and an upper cover 14. Inside the body 12, a filter material (not shown) 'can be accommodated with threads 1 on its surface. The upper cover 4 is provided with a water inlet hole 16 and a water outlet hole 18, and a thread 19 is formed on the inner surface of one end. When the upper cover 14 is locked to the thread at one end of the body 10 with the ridge pattern 19, both the water inlet hole 16 and the water outlet hole 18 can communicate with the interior of the body 2 so that 4 water can pass through. The water inlet 16 enters, passes through the filter material in the body 12, and flows out from the water outlet 18. The combination of the plurality of filter cores 10 is connected to the water inlet hole 16 of the other filter core 10 through the water outlet hole 18 of one core. After such a combination, water can effectively remove impurities in the water after passing through each filter element 10. However, after a period of use, the filter material inside the filter core 10 will gradually lose its effect, so the filter material must be replaced. However, regardless of whether the filter material in the main body 2 is replaceable or the body and the body must be released and locked on the main body 12 is discarded. However, the filter core 10 will be filled with water when it is used, so the meshing of the filter core lines 10 and 13 is more urgent, and it is very inconvenient and laborious to cooperate with the tool 'to do this. 1 2s is an integral type of disposable type, which must be covered by 14 to replace or rearen the filter material. 'The body 12 and the upper cover 14 have a pressure difference between the inside and outside, causing the screw user to use greater force Separated from the body 12 by 14 and is being manipulated

In addition, the upper cover described in the above technology 4 and the main body 12 are direct

M244961 V. Creation instructions (2) The lock structure is prone to cause stress problems at the lock position, so there will be additional reinforcement structures at the lock position, which will cause inconvenience in manufacturing. [Creation content] In view of the shortcomings of the filter core disclosed in the prior art that is laborious and inconvenient to disassemble, this creation is to provide a labor-saving and easy-to-operate filter lock structure to overcome the inconvenience caused by the prior technology. According to the above-mentioned purpose and effect, a flange is formed at one end of the body, a thread is made on an outer surface of the upper cover, and an outer lock type lock ring is arranged. In this way, the upper cover and the main body are grouped together, and the lock ring and the upper cover are screwed together, and the lock ring and the flange shape 4 of the main body are tightly combined, so that the upper cover, the The body and the lock ring are combined together, and the thread engagement between the lock ring and the upper cover is not affected by the pressure difference between the inside and outside of the body, so the lock ring can be released in a labor-saving and convenient operation to facilitate Replace the filter material inside the body, or discard the body. The following is a detailed description based on the purpose, effect, and structural configuration disclosed in this creation. [Explanation of the embodiment] Please refer to the second figure, which discloses a main body 20, an upper cover 30, and a lock ring 40. Wherein: One end of the body 20 is provided with a ring-shaped flange 22, and an inner tube 24 is housed inside the body 20, and the inside of the inner pipe 24 can be used for containing filter material, such as cotton core or active dish. material. In addition, an end group of the inner tube 24 is provided with a cap 26 and a stop ring 28.

Page 6 M244961 V. Creation instructions (3) The upper cover 30 has a water inlet hole 32 and a water outlet hole 34, and one end surface of the upper cover 30 is provided with threads 36. The locking ring 40 is a hollow ring body. The inner wall surface is provided with a thread 42, and the periphery of the opening at one end forms a stopper 44. Please refer to the ends not shown in Figures 3 and 4, and the upper cover 30 presses the water stop washer 28. The locking ring 40 is sleeved on the periphery of the main body 20, and the outer diameter of the end of the upper cover 30 with the thread 36 is larger than the outer diameter of the main body 20. Therefore, the thread 42 formed on the inner wall surface of the locking ring 40 may Engages with the thread 36 of the upper cover 30. The ^ portion of the lock ring 40 is in contact with the flange 22 of the main body 20. As the lock ring 40 is locked between the upper ring 30 and the upper ring 30, the stopper 44 of the lock ring 40 will more tightly abut against the flange 22, so that the upper cover 30 and the main body 20 are more closely sealed. . The water inlet hole 32 and the water outlet hole 34 provided in the upper cover 30 communicate with the interior of the body 20. Λ = is the component composition of one embodiment of this creation, and ==. 2 After entering through the water inlet, it flows into the body and passes through i: It flows out from the water outlet 34. The plural numbers of hearts are grouped with each other ° = to form two filtering systems to improve the filtering effect. As shown in the fourth picture of Ming Zai Mai, the lock ring 40 and the upper Yun 30 f 42; 36 mingling household's weight to stay on the upper cover 3. Internal water; force ;: 间: between…, does not cause the thread%, 22, so 4 = r0 is to push the flange of the body 20 and the body 2 with the supporting portion 44.内 Π ;: 2 ° axial detachment of the body. In other words, the pressure does not affect the pressure, and the difference acts on the movement of the body 20 in the radial direction of the body 20 along the axial direction of the body 20. because

Page 7 M244961 V. Creation Instructions (4) From the above description, the user can unscrew the lock ring 40 under a relatively small force operation, and the lock ring 40 can be easily moved in the axial direction of the body 20 Mobile, so this creation has the effect of labor saving and easy operation. Please refer to the fifth figure, which shows a combination of a disposable body 21 and the upper ring 30 and the lock ring 40. The main body 21 is integrated with the filter material and is provided with a flange 22 on the outer surface. The structure of the upper cover 30 and the lock ring 40 is the same as that of the previous embodiment and will not be described repeatedly. In use, the lock ring 40 is sleeved on the periphery of the main body 21, and the lock ring 40 is engaged with the thread 36 of the upper cover 30 by a thread 42, and the lock ring 40 resists the protrusion of the main body 21 with a stop 44.缘 22。 Edge 22. (2) The lock ring 40 is tightly locked with the upper cover 30, and the stopper 44 and the flange 22 also form a tight abutment state ', so that the upper cover 30 and the main body 21 are brought into close contact. ^ Because the pressure difference between the inside and outside of the filter does not cause excessive tight engagement between the lock ring 40 and the upper chin 30, and the lock ring 40 does not form an excessively tight state corresponding to the body 21, the user can In the case of labor saving and simple operation without using tools, the locking ring 40 is released to facilitate separation of the upper cover 30 and the main body 21. Furthermore, since the upper cover 30 and the main body 20 are combined by abutting, and cooperated with the locking connection of the lock ring, the present invention provides an external lock-type structure. This structure can eliminate the upper cover 30 and the main body. For the stress problem between 20, relative _ not only need to provide a reinforcing structure at the joint position, so the effect of simple manufacturing can be achieved. = The above is the preferred embodiment and design drawings of this creation, but the user, target example, and §50 drawings are only examples, and are not intended to limit this M244961.
