[0031] Please see Figures 1 to 4 This utility model provides an exemplary capsule filter, comprising:

[0032] The filter element cylinder 1 has a first end and a second end;

[0033] The first end cap 2 is set at the first end of the filter element cylinder 1, and the first end cap 2 has a sample inlet pipe 4 on the side away from the filter element cylinder 1.

[0034] The second end cap 3 is set at the second end of the filter element cylinder 1. The second end cap 3 has a sample outlet pipe 5 on the side away from the filter element cylinder 1.

[0035] Both the sample inlet pipe 4 and the sample outlet pipe 5 include a vertical section 11 and an anti-detachment section 12 connected to each other. The diameter of the anti-detachment section 12 gradually decreases in the direction away from the filter element cylinder 1 and forms a frustum structure.

[0036] Specifically, the anti-detachment section 12 is connected to the vertical section 11 to form an inverted cone-shaped frustum structure. The hose is sleeved on the anti-detachment section 12. The large diameter part of the frustum structure can expand the hose. The hose has elastic deformation capability, which allows the sample inlet connector 4 and the sample outlet connector 5 to be better connected to the hose.

[0037] In the capsule filter provided by this utility model, an anti-detachment section 12 is provided on the sample inlet pipe 4 and the sample outlet pipe 5. The anti-detachment section 12 forms a frustum structure. When the sample inlet pipe 4 and the sample outlet pipe 5 are connected to the hose, the hose is sleeved on the anti-detachment section 12. The frustum structure forms a certain taper, which increases the contact area between the pipe and the hose, making the connection between the hose and the pipe more effective and forming a better sealing effect.

[0038] In this embodiment, a filter element is provided inside the filter element cylinder 1, and an installation ring 13 is provided on the second end cap 3 for fixing to the filter element. The fixing method between the filter element and the installation ring 13 includes fusion welding and welding. Specifically, the installation ring 13 is located in the middle of the second end cap 3, and the filter element is located in the middle of the filter element cylinder 1. The filter element is installed on the installation ring 13 by fusion welding or welding, thereby achieving the fixing of the filter element.

[0039] It should be noted that both the first end cap 2 and the second end cap 3 are designed as pagoda structures. Existing technology cannot be directly applied to guide design and production or serve as a design reference for the design scheme of the pagoda-shaped quick connection device for the capsule filter. There are no restrictions on the various dimensions of the pagoda, but the dimensions of the pagoda will affect the connection strength between the interface and the hose. Therefore, it is necessary to design reference the dimensions of the pagoda structure.

[0040] In one embodiment, the pagoda structure is a single-layer pagoda with a diameter of 24.3-26.4 mm.

[0041] In one embodiment, the pagoda structure is a 1 / 2 single-layer pagoda with a diameter of 12.2-15.2 mm.

[0042] In one embodiment, the pagoda structure is a 3 / 8 single-layer pagoda with a diameter of 8.8-11.2 mm.

[0043] In one embodiment, the pagoda structure is a 9 / 16 single-layer pagoda with a diameter of 14-16.3 mm.

[0044] In one embodiment, the pagoda structure is a 3 / 4 single-layer pagoda with a diameter of 19-22 mm.

[0045] Understandably, the pagoda structure includes single-layer, 1 / 2 single-layer, 3 / 8 single-layer, 9 / 16 single-layer, and 3 / 4 single-layer configurations. The diameter range of each pagoda structure is designed so that when the diameter of the pagoda structure is within the above range, the deformation of the hose is within 15%, achieving a good sealing effect and solving the connection strength problem between the pagoda and the hose.

[0046] In this embodiment, the first end cap 2 is also provided with an exhaust pipe 6 for venting. The exhaust pipe 6 is connected to the interior of the first end cap 2. The exhaust pipe 6 is also provided with a first valve plug 8 for controlling opening and closing. The gas in the capsule filter can be discharged through the exhaust pipe 6 to achieve a better sample filtration effect.

[0047] Furthermore, the second end cap 3 is also provided with a drain pipe 7 for discharging waste liquid. The drain pipe 7 is connected to the interior of the second end cap 3. The drain pipe 7 is also provided with a second valve plug 9 for controlling opening and closing. The waste liquid generated by filtration can be discharged through the drain pipe 7 to achieve a better sample filtration effect.

[0048] In detail, both the first valve plug 8 and the second valve plug 9 have a sleeve portion 14 and a blocking portion 15. The blocking portion 15 extends into the exhaust pipe 6 and the sewage pipe 7 and seals them. The exhaust pipe 6 and the sewage pipe 7 have openings 10 inside the second end cap 3. The head of the blocking portion 15 matches the opening 10. The sleeve portion 14 is sleeved on the exhaust pipe 6 and the sewage pipe 7. The end of the sleeve portion 14 extends in a direction away from the exhaust pipe 6 and the sewage pipe 7 and has a plug-in portion 17. By holding the plug-in portion 17, the first valve plug 8 and the second valve plug 9 can be pulled out from the exhaust pipe 6 and the sewage pipe 7 or inserted into them, respectively.

[0049] In some embodiments, a fastener 16 is also provided at the connection between the vertical section 11 and the anti-detachment section 12. When the hose is sleeved on the anti-detachment section 12, the fastener 16 is installed at the connection to clamp the hose at the connection, thereby further improving the hose's anti-detachment effect and sealing effect. Specifically, the fastener 16 can be a cable tie, a plastic hose clamp, a metal hose clamp, etc., and is not limited to this. Preferably, the metal hose clamp has the best connection strength. The hose is clamped at the connection between the vertical section 11 and the anti-detachment section 12 by installing the metal hose clamp.

[0050] It is worth noting that the length of the vertical section 11 is set to 18.08-18.16mm. This design allows the fastener 16 to have enough space to clamp the hose, solving the problem of insufficient fastening and locking limits.

[0051] In summary, in the capsule filter provided by this utility model, by setting anti-detachment sections 12 on the sample inlet connector 4 and the sample outlet connector 5, the anti-detachment sections 12 form a frustum structure. When the sample inlet connector 4 and the sample outlet connector 5 are connected to the hose, the hose is sleeved on the anti-detachment section 12. The frustum structure forms a certain taper, which increases the contact area between the connector and the hose, making the connection between the hose and the connector more effective and forming a better sealing effect.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
