[0024] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may extend based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0025] refer to Figures 1 to 3 The present invention provides a water filter 1, comprising: a first cylinder 10 and a filter unit 20. The top of the first cylinder 10 has a first water inlet (not shown), the side end 10a of the first cylinder 10 has a first recess 11, the first recess 11 is provided with a first water outlet 12, and the first water outlet 12 is connected to the first recess 11. Preferably, the first water inlet and the second water inlet 21 are arranged opposite to each other along the same straight line. The water source to be filtered flows in through the first water inlet of the first cylinder 10, flows out from the first water outlet 12, and flows into the filter unit 20.

[0026] The first concave portion 11 located in the first barrel 10 is the inner surface, and the inner surface of the first concave portion 10 is connected to the first water outlet 12. The inner surface of the first concave portion 11 includes a first portion 11a and a second portion 11b, and the first water outlet 12 is located between the first portion 11a and the second portion 11b. The first portion 11a is connected to the side wall 10b of the first barrel 10, and the first portion 11a extends from the connection with the side wall 10b of the first barrel 10 along the direction from the top end to the bottom end of the first barrel 10 ( Figure 2 The first concave portion 11 is inclined downward to connect with the first water outlet 12, and the second portion 11b is respectively connected with the first water outlet 12 and the bottom wall 10c of the first cylinder 10. This arrangement allows the impurities such as silt in the water source to flow along the inner surface of the first concave portion 11 to the bottom of the first cylinder 10, reducing the amount of impurities such as silt flowing from the first water outlet 12 into the filter unit 20, thereby improving the filtering efficiency.

[0027] Preferably, the first portion 11a extends from the connection with the side wall 10b of the first cylinder 10 along the direction from the top to the bottom of the first cylinder 10 ( Figure 2 The angle of downward tilt (indicated by the direction A in the middle) Figure 2 Preferably, the angle of inclination is 33°.

[0028] In addition, the side end 20a of the filter unit 20 of the present invention has a second water inlet 21, which is connected to the first water outlet 12 to receive the water source in the first cylinder 10. The side end 20a of the filter unit 20 also has a second water outlet 22, and a filter core 25 is provided between the second water inlet 21 and the second water outlet 22. The filter unit 20 is located in the first recess 11 and is detachably connected to the first cylinder 10. The water source flowing into the filter unit 20 through the second water inlet 21 is filtered by the filter core 25 and then flows out from the second water outlet 22 of the filter unit 20. The user can receive the filtered water source at the second water outlet 22 of the water filter 1 for drinking.

[0029] The filter unit 20 of the present invention is detachably connected to the first cylinder 10. On the one hand, after the water filter 1 has been used for a long time, a new filter unit 20 can be replaced. On the other hand, the filter unit 20 with different filtering capabilities can be replaced according to water filtration requirements, which is more convenient to use and improves user experience.

[0030] In addition, the water filter 1 further comprises a cover body 30 , on which a handle 31 is provided. The cover body 30 covers the first water inlet, and the handle 31 facilitates the transportation of the water filter 1 .

[0031] Preferably, reference Figure 2 , the second part 11b of the first concave portion 11 is perpendicular to the bottom wall 10c of the first cylinder 10. This arrangement allows the impurities such as silt in the water source to flow to the bottom of the first cylinder 10 along the first part 11a (inclined surface) of the first concave portion 11, and to flow to the bottom of the first cylinder 10 along the second part 11b, thereby reducing the amount of impurities such as silt flowing into the filter unit 20 from the first water outlet 12 and improving the filtering efficiency.

[0032] Since the first water outlet 12 is located between the first part 11a and the second part 11b, the opening of the first water outlet 12 faces the side wall 10b of the first cylinder 10. Further, the amount of impurities such as silt in the water source flowing into the filter unit 20 from the first water outlet 12 is reduced, further improving the filtering efficiency.

[0033] Specifically, the first water outlet 12 is located in the first cylinder 10 and is convexly disposed on the first concave portion 11. Figure 3, the second water inlet 21 of the filter unit 20 is located outside the filter unit 20 and is protruding from the side end 20a of the filter unit 20. After the filter unit 20 is disposed in the first recess 11 of the first cylinder 10, the second water inlet 21 is inserted into the first water outlet 12, and the two are threadedly connected to achieve a detachable connection between the filter unit 20 and the first cylinder 10. However, the connection method is not limited to this, and it only needs to be able to achieve a detachable connection. Moreover, after the filter unit 20 is disposed in the first recess 11 of the first cylinder 10, the outer surface of the filter unit 20 is fitted with the outer surface of the first recess 11. The second water outlet 22 is located outside the filter unit 20 and is protruding from the side end 20a of the filter unit 20. Combined with Figure 1 As shown, after the filter unit 20 is disposed in the first recess 11 of the first barrel 10 , the second water outlet 22 of the filter unit 20 protrudes out of the first barrel 10 , and the user can receive filtered water at the second water outlet 22 .

[0034] refer to Figure 1 and Figure 3 , the filter unit 20 of the present invention is provided with a plurality of accommodating parts 26, each accommodating part 26 is provided with a filter core 25, and the filter core 25 is detachably connected to the accommodating part 26. That is, the filter unit 20 of the present invention has a plurality of filter cores 25, not only the filter unit 20 is replaceable, but also the filter core 25 in the filter unit 20 is replaceable. In addition, there is no restriction on the selection of the filter core 25, as long as it can achieve filtering; according to different filtering requirements, the selected filter core 25 is also different. The filter core 25 of the present invention includes one or more of the following: filter net, coarse cloth yellow sand, activated carbon, porous ceramics and porous silver ion ceramics, but is not limited thereto.

[0035] refer to Figure 3 In this embodiment, the filter unit 20 has five filter cores 25, which are arranged in sequence from the top to the bottom of the filter unit 20. Among them, the first filter core 25a is a filter mesh, the second filter core 25b is coarse cloth yellow sand, the third filter core 25c is activated carbon, the fourth filter core 25d is a porous ceramic, and the pore size of the fourth filter core 25d is 20 to 10 microns; the fifth filter core 25e is a porous silver ion ceramic. Preferably, the fourth filter core 25d is a 20 to 10 micron porous ceramic, the fifth filter core 25e is a 0.2 to 1 micron porous silver ion ceramic, and the pore size of the fifth filter core 25e is 0.2 to 1 micron.
