Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a composite physical sterilization filter element and a water purifier. Background Art

[0002] The pre-treatment filter element at the front end of the large-flow reverse osmosis water purifier is relatively small in size. Due to the large water flow rate during operation, there will be residual chlorine in the water. Without adding a post-carbon filter element, the water will have an odor. The odor of the pure water end can be solved by adding a post-carbon filter element. However, after using the post-carbon filter element (due to the honeycomb structure of the carbon) for a period of time, bacteria will continue to breed in the carbon honeycomb, resulting in excessive bacteria at the water end.

[0003] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0004] The technical problem to be solved by the present invention is that, in view of the above-mentioned defects of the prior art, a composite physical sterilization filter element is provided, which not only solves the problem of odor in the outlet water but also solves the problem of excessive bacteria in the post-carbon filter.

[0005] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0006] A composite physical sterilization filter element comprises a shell, wherein two ends of the shell are respectively provided with a water inlet and a water outlet;

[0007] A pickled carbon rod and an external pressure ultrafiltration membrane are respectively arranged in the shell, the pickled carbon rod is arranged at the water inlet end, and the external pressure ultrafiltration membrane is arranged at the water outlet end;

[0008] The water inlet end of the pickled carbon rod is provided with a water inlet end cap, the water outlet end of the external pressure ultrafiltration membrane is provided with a first water stop end cap, a second water stop end cap is provided between the pickled carbon rod and the external pressure ultrafiltration membrane, and a water inlet space is formed between the water inlet end cap and the shell;

[0009] The first water-stop end cover and the second water-stop end cover are both provided with O-rings.

[0010] Preferably, a plurality of exhaust filaments are provided in the external pressure ultrafiltration membrane.

[0011] Preferably, the exhaust wire is arranged in a U shape.

[0012] Preferably, a guide groove is provided on the outlet side of the external pressure ultrafiltration membrane.

[0013] Preferably, two O-rings are provided on each of the first water-stopping end cover and the second water-stopping end cover.

[0014] The present application also provides a water purifier, which includes the composite physical sterilization filter element described above.

[0015] Compared with the existing technology, the composite physical sterilization filter provided by the utility model has the following beneficial effects:

[0016] The water passes through the water inlet shell and is introduced into the gap between the pickled carbon rod and the shell through the first water-stop end cap. The lower end of the pickled carbon rod is provided with a second water-stop end. The water will only penetrate through the outside of the pickled carbon rod to the inside of the pickled carbon rod for filtration. The water filtered by the pickled carbon rod flows into the external pressure ultrafiltration membrane to be filtered again, thereby achieving the effect of physical sterilization. The filtered water is pure water itself without impurities. The external pressure ultrafiltration membrane only filters the carbon rod for bacteria exceeding the standard under long-term use, so the service life will be very long, which solves the problem of bacteria exceeding the standard in the post-carbon filter element and extends the service life of the post-filter element.

The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application.

[0023] Water enters the shell 10 through the water inlet 101, and is introduced into the gap between the pickled carbon rod 02 and the shell 10 through the first water stop end 07 cover. The lower end of the pickled carbon rod 02 is provided with a second water stop end cover 03. The water will only penetrate through the outside of the pickled carbon rod 02 to the inside of the pickled carbon rod 02 for filtration. The water filtered by the pickled carbon rod 02 flows into the external pressure ultrafiltration membrane 05 to be filtered again, thereby achieving the effect of physical sterilization. The filtered water is pure water itself without impurities. The external pressure ultrafiltration membrane 05 only filters the bacteria that exceed the standard in the pickled carbon rod 02 after long-term use, so the service life will be very long, which solves the problem of bacteria exceeding the standard in the post-carbon filter element and extends the service life of the post-filter element.

[0026] During specific implementation, a guide groove 09 is provided on the outlet side of the external pressure ultrafiltration membrane 05 .

[0027] An exhaust wire 06 is provided inside the external pressure ultrafiltration membrane 05, and the compressed air in the water body can be discharged through the exhaust wire 06 (to prevent the water from entering the ultrafiltration membrane after being pumped to generate compressed air, thereby generating a large number of bubbles). A first water-stop end cap 07 and an O-ring 04 are provided at the bottom of the external pressure ultrafiltration membrane 05. The water body can only penetrate from the outside of the external pressure ultrafiltration membrane 05 to the inside for filtration. A guide groove 09 is provided at the water outlet end of the external pressure ultrafiltration membrane 05. The water body is filtered by the external pressure ultrafiltration membrane 05, and the water body flows into the guide groove 09, and flows out through the water outlet 102 after being guided by the guide groove 09.

[0028] In a specific implementation, two O-rings 04 are provided on each of the first water-stopping end cover 07 and the second water-stopping end cover 03 .
