[0060] In some embodiments, an annular sealing groove 42 is further provided on the side wall of the top cover 4 , and a third sealing ring is provided on the annular sealing groove 42 for sealing between the top cover 4 and the second connecting member 3 .

[0061] Specifically, the top cover 4 is cylindrical, and the diameter of the portion of the top cover 4 inserted into the second connecting member 3 is equal to the inner diameter of the second connecting member 3. An annular protrusion is also provided on the top of the top cover 4, and the outer diameter of the annular protrusion is larger than the inner diameter of the second connecting member 3. The top cover 4 is inserted into the second connecting member 3, and the annular protrusion is limited by the top surface of the second connecting member 3, so that the top cover 4 cannot fall down, and then the annular protrusion is fixed by the buckle structure, so that it cannot come out of the second connecting member 3. At least one annular sealing groove 42 is provided on the side wall of the top cover 4, which is used to install a third sealing ring. The third sealing ring can make the top cover 4 and the second connecting member 3 sealed and ensure the sealing of the buckle structure.

[0062] In some embodiments, the buckle structure includes:

[0063] A buckle strip 5, wherein the buckle strip 5 is in an "Ω" shape and is provided with a buckle protrusion 51, and the buckle protrusion 51 cooperates with the buckle through hole 32;

[0064] A tension spring 6, the left and right ends of which are respectively connected to the left and right ends of the buckle strip 5, for fixing the buckle strip 5 on the first buckle groove 31; and

[0065] A pull rope 7 , which is connected to the right end of the tension spring 6 and is used to pull the right end of the tension spring 6 away from the buckle strip 5 .

[0066] In some embodiments, tension spring holes 52 are provided at both ends of the buckle strip 5 .

[0067] In some embodiments, the tension spring 6 comprises:

[0068] A left hook 61, the left hook 61 passes through the tension spring hole 52 at the left end of the buckle strip 5 and cannot be separated from the tension spring hole 52;

[0069] A left tension spring 62, wherein the left tension spring 62 is connected to the left hook 61;

[0070] A right hook 63, the right hook 63 passes through the tension spring hole 52 at the right end of the buckle strip 5, and cannot be separated from the tension spring hole 52 in a vertical state;

[0071] a right tension spring 64, wherein the right tension spring 64 is connected to the right hook 63, and the pull rope 7 is connected to the right tension spring 64; and

[0072] A connecting bar 65 , two ends of which are respectively connected to the left tension spring 62 and the right tension spring 64 .

[0073] Specifically, a tension spring, also called a tension spring, is a helical spring that bears axial tension. Tension springs are generally made of round cross-section materials. When not under load, the coils of a tension spring are generally tight and there is no gap between them. When the two ends of the tension spring are pulled apart, the spring will try to pull them back together.

[0074] The first and second latching grooves 31 are provided with an annular first latching groove 31 on the upper end side wall of the second connecting member 3. At the same time, at least one latching through hole 32 is also provided on the first latching groove 31, that is, on the side wall of the second connecting member 3. The latching through hole 32 is communicated with the first latching groove 31, and the latching through hole 32 is arc-shaped; the latching strip 5 is in an arc shape and has a certain elasticity. The inner diameter of the widest part is equal to the inner diameter of the first latching groove 31. The inner side of the latching strip 5 is provided with a latching convex body 51 corresponding to the latching through hole 32. After the latching strip 5 is inserted into the first latching groove 31, the latching convex body 51 can pass through the latching through hole 32 and be inserted into the second latching groove 41 of the top cover 4, and then the two ends of the tension spring 6 are connected to the two ends of the latching strip 5 to form a closed loop, so that the latching strip 5 cannot come out of the first latching groove 31, and the top cover 4 can no longer be detached from the second connecting member 3. The left hook 61 and the right hook 63 are both U-shaped. The left hook 61 passes through the tension spring hole 52 at the left end of the buckle strip 5 and then is shaped. After being shaped, the left hook 61 can no longer come out of the tension spring hole 52. The right hook 63 is divided into three sections, such as Fig.12 As shown, the S1 segment connected to the right tension spring 64, the S2 segment connected to the S1 segment, and the S3 segment connected to the S2 segment, S1 and S2 are perpendicular to each other, S3 is parallel to S1, and the length of S3 is greater than the diameter of the tension spring hole 52 at the right end of the buckle strip 5, so that after the right hook 63 passes through the tension spring hole 52, it cannot be directly pulled out of the tension spring hole 52 in a vertical state. At this time, even if a lot of force is used, it cannot be pulled out, so that the right hook 63 is prevented from easily coming out of the tension spring hole 52 during action, and the top cover 4 is prevented from being separated from the tank body 1; when the top cover 4 is to be removed, the connecting strip 65 is pressed downward to tilt the right hook 63, that is, S1 and S3 are tilted, and at this time, the pull rope 7 is pulled upward or obliquely upward, and S3 can be tilted and enter the tension spring hole 52 as a whole, as shown in FIG. Fig.16 As shown, the right hook 63 can be easily disengaged from the tension spring hole 52, so that the buckle strip 5 can be removed to separate the top cover 4 from the tank body 1. It should be noted that because the adsorbent tank is portable, its volume is small, so the activity space is also small, and it is not convenient to tilt the right hook 63 directly by hand. Therefore, in this embodiment, a pull rope 7 is provided to pull the right hook 63. After the pull rope 7 passes through the right tension spring 64 from right to left, a knot is tied at the end of the pull rope 7, so that when the pull rope 7 is pulled, the pull rope 7 cannot be detached from the right tension spring 64, and no displacement occurs.

[0075] In summary, the present invention includes a tank body 1, a first metal part 11 is integrally formed on the side wall of the tank body 1, and a second metal part 12 is integrally formed on the top of the tank body 1; a first connecting member 2, the first connecting member 2 is fixedly connected to the first metal part 11; a second connecting member 3, the second connecting member 3 is fixedly connected to the second metal part 12, a first buckle groove 31 is provided on the side wall of the second connecting member 3, and a buckle through hole 32 is provided on the first buckle groove 31; a top cover 4, the top cover 4 is detachably connected to the second connecting member 3, a second buckle groove 41 is provided on the side wall of the top cover 4, and the second buckle groove 41 matches the buckle through hole 32; and a buckle structure, the buckle structure is arranged on the first buckle groove 31 and is snapped into the second buckle groove 41, and is used to make the top cover 4 fixedly connected to the second connecting member 3. The above design makes it easier to connect the tank body with other components, and the sealing performance is also better.

[0076] The above-mentioned embodiments only express one or more implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
