[0013] Preferably, the cup cover is connected to the cup body via threads.

[0014] In the outdoor filter water cup provided by the present invention, during use, each sub-filter layer in the filter rod can respectively have the functions of filtering solid residues or microorganisms, sterilizing, ultraviolet disinfection, etc. The user uses the valve-type suction nozzle to pass the liquid in the cup through each sub-filter layer in turn along the water flow path to reach the top, which plays the role of rapid filtering, sterilization and disinfection. At the same time, each sub-filter layer of the filter rod can be freely combined and spliced ​​to adapt to water sources in different environments and achieve the best filtering and purification effect.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] In one embodiment, if Figures 1 to 4As shown, there is provided an outdoor filtered water cup, comprising a cup body 1, a cup cover 2 and a filter rod 3; wherein the cup cover is connected to the cup body by a thread; a valve-type suction nozzle 4 is arranged at the upper end of the cup cover, and a filter rod is movably connected to the lower end of the cup cover; the filter rod is cylindrical as a whole, and is spliced ​​by multiple sub-filter layers 31, the outer wall of each sub-filter layer is closed, and a filter net or filter material is arranged inside each sub-filter layer, and a water flow path is provided between each sub-filter layer, and the water flow path is communicated with the valve-type suction nozzle.

[0023] Preferably, the filter rod includes six sub-filter layers from bottom to top, namely, a stainless steel filter 32, a ceramic filter 33, a first compressed activated carbon rod 34, a nano-ultrafiltration membrane 35, a second compressed activated carbon rod 36, and an ultraviolet sterilization part 37. Among them, the stainless steel filter and the ceramic filter can filter most of the solid residues in the liquid; the compressed activated carbon rod can deeply absorb the substances harmful to the human body such as discoloration, odor, residual chlorine, halogenated hydrocarbons and organic matter in the water, effectively improving the taste of the water; the nano-ultrafiltration membrane can filter microorganisms, such as bacteria, fungi, etc.; the ultraviolet sterilization part is used for sterilization and disinfection.

[0024] It is understandable that, since the sub-filtering layers can be freely combined and spliced, the arrangement order of the sub-filtering layers can also be freely adjusted according to the needs of actual applications. At the same time, the length of the filter rod is equivalent to the height of the cup body, which facilitates the liquid to flow upward from the bottom layer of the cup body and pass through more filter layers.

[0025] Specifically, each sub-filtering layer is connected by a quick release buckle 5, but not limited thereto. A waterproof silicone ring 6 is also provided between each sub-filtering layer to enhance airtightness and prevent the liquid to be purified from flowing out of the water flow path during the rising process.

[0026] Furthermore, the valve type suction nozzle is fixed to the upper end of the cup cover through a rotating shaft; the upper end of the cup cover is also provided with a groove 21 for accommodating the valve type suction nozzle; when the valve type suction nozzle is lying in the groove, the upper end of the water flow path is closed; when the valve type suction nozzle is standing up, the upper end of the water flow path is opened.

[0027] Furthermore, a handle 22 is provided on the cup cover to facilitate carrying the cup.

[0028] Furthermore, a straw 38 extends from the top of the filter stick. When the filter stick is placed in the cup body, the straw is connected to the mouthpiece, which is convenient for the user to suck water; or the filter stick can be used directly, and the user can drink water directly at the water's edge through the straw.

[0029] Furthermore, the filter material includes but is not limited to compressed activated carbon, nano ultrafiltration membrane, bioactive ceramics, silver ion antibacterial materials, etc.

[0030] The above is an explanation of the outdoor filter water cup of the present invention to help understand the present invention; however, the implementation mode of the present invention is not limited to the above-mentioned embodiments, and any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
