Referring to FIGS. 1 and 2, a portable purified water bottle having filtering and sterilizing functions according to the present invention will be described.

The portable purified water bottle having filtration and sterilization functions according to the present invention largely includes a body 100, a lower cap 200, a sterilization filter unit 300, an upper cap 400, and a filtration filter unit 500. .

First, the body 100 has a cylindrical shape with a hollow inside, and openings 110a and 110b are formed at upper and lower portions. The body 100 may mean a general portable water bottle shape.

A thread is formed on the outer circumferential surface 130 of the upper portion of the body 100 to be screwed into the inner circumferential surface of the upper cap 400 to be described later. The thread may mean a female thread or a male thread.

In addition, a male screw thread for screwing with the inner circumferential surface 210 of the lower cap 400 to be described later is formed on the lower outer circumferential surface 120 of the body 100.

The body 100 may be made of a metal material such as aluminum or stainless steel, or a synthetic resin material including polyethylene, polypropylene, ethylene vinyl acetate, polyethylene terephthalate, polycarbonate, etc., but is not limited thereto. All materials used for water bottles, baby bottles, and drinking water containers can be used.

In addition, the body 100 may have a part of the cylindrical circumferential wall formed in a groove shape so that it can be easily gripped with one hand. This may mean a shape such as a Coke bottle.

3 is a perspective view showing another embodiment of a body constituting a portable purified water bottle having filtering and sterilizing functions according to the present invention.

Meanwhile, as an additional embodiment, referring to FIG. 3 , the body 100 may include an outer body 101 and an inner body 102 in a double cylindrical structure.

The inner body 102 is formed with a diameter smaller than that of the outer body 101, and a body space 103 is formed between the inner body 102 and the outer body 101. The body space 103 is a space provided for design, and can be used in various ways such as inserting liquid or objects, paper, and fabric for design.

Next, the lower cap 200 is coupled to the lower portion of the body 100 to close the opening 110b formed in the lower portion of the body 100 . That is, when water is injected into the opening 110a formed in the upper part of the body 100, the water is prevented from being discharged into the opening 110b formed in the lower part of the body 100.

4 is a perspective view showing a lower cap and a sterilization filter part constituting a portable purified water bottle having filtration and sterilization functions according to the present invention.

Referring further to FIG. 4 , the lower cap 200 has a cylindrical shape and may mean a general lid shape.

The lower cap 200 has a female screw thread for coupling with the male screw thread of the lower part of the body 100 on the inner circumferential surface 210.

Next, the sterilization filter unit 300 includes a sterilization filter housing 310 and a plurality of ceramic balls 320.

The sterilization filter housing 310 is coupled to the inner lower portion of the lower cap, and a plurality of filtering through holes 311 are formed in the main wall in a cylindrical shape.

Referring to FIG. 4 , the sterilizing filter housing 310 has a cylindrical shape with an upper end closed and an open lower end.

At the bottom of the sterilization filter housing 310, a locking jaw 312 is formed that protrudes outward along the outer circumference. The locking jaw 312 is rotationally coupled to a female thread formed on the inner circumferential surface 210 of the lower cap. Through this coupling structure, it is possible to easily replace the ceramic ball 320 inside the sterilization filter housing 310.

The filtering through hole 311 is formed with a smaller diameter than that of the ceramic ball 320 to be described later. Therefore, the filtering hole 311 allows the water stored in the water bottle to flow into and out of the sterilizing filter housing 310 through the filtering hole 311, and the ceramic ball 320 is the sterilizing filter housing 310. ) will not be able to escape to the outside.

In addition, the filtering through hole 311 may be formed in a polygonal shape including a circular shape or a triangular or quadrangular shape, but is not limited thereto. That is, it is preferable that the size and shape of the sterilization filter housing 310 and the shape of the plurality of filtering holes 311 are formed in a structure for maximum contact between the contaminated water in the water bottle and the ceramic balls 320 to be described later.

The ceramic ball 320 has a non-toxic alumina ceramic spherical shape, and is coated with silver iodide (AgI), which has low solubility in water and excellent antibacterial performance, on the surface.

Silver iodide has the property of killing microorganisms by changing the protein structure in microorganisms. Silver iodide directly contacts water to produce a primary antibacterial effect, and silver ions dissolved in water and iodine ions indirectly contact each other to produce a secondary antibacterial effect. bring That is, the ceramic ball 320 has an effect of sterilizing pathogenic bacteria and viruses included in water (raw water).

Therefore, the portable purified water bottle having filtering and sterilizing functions can have a sterilizing effect with a simple structure in which the water bottle is sterilized by simply shaking the water bottle due to the ceramic ball (AgI antibacterial ball) built into the sterilizing filter housing 310 in the water bottle.

On the other hand, a water treatment device for sterilization using a chlorine method, ultraviolet rays, or ozone requires a complicated method such as electrolysis and requires a lot of cost such as installation of electrical equipment. However, since the silver iodide method can be sterilized (antibacterial) with a small ball with a diameter of about 5 to 10 mm, there is an advantage in that it does not require the installation of such electrical equipment.

The ceramic ball 320 coated with silver iodide (AgI) according to the present invention may preferably have a diameter of 3 to 5 mm.

This is because, when they have the same weight (amount), a ceramic ball with a diameter of 3 to 5 mm has an increased surface area compared to a ceramic ball with a diameter of 10 mm, and the contact area (surface area) with water (contaminated water) in the water bottle is increased. Since the diameter is larger than that of a ceramic ball having a diameter of 10 mm, the sterilization effect can be increased.

More specifically, ceramic balls with a diameter of 3 to 5 mm are provided in a larger number than ceramic balls with a diameter of 10 mm in the same sterilization filter housing 310. When the total surface area of each 10 mm ceramic ball is calculated, a ceramic ball with a diameter of 5 mm is more than twice as large as a ceramic ball with a diameter of 5 mm. This means that when using a ceramic ball of the same weight, if a ceramic ball with a diameter of 5 mm is used than a ceramic ball with a diameter of 10 mm, the silver iodide surface area in contact with the same water (contaminated water) in the water bottle is more than twice larger, reaching a certain level of sterilization. This means that the required time is shortened or higher sterilization efficiency can be displayed at the same time. Therefore, when using the same weight, using a small diameter rather than a large diameter can increase the sterilization effect.

On the other hand, when the diameter of the ceramic ball 320 is less than 3 mm, it is difficult to coat the surface of the ceramic ball with silver iodide. Therefore, it is preferable that the diameter of the ceramic ball 320 is 3 to 5 mm.

On the other hand, the body 100 may be formed such that the diameter of the body 100 becomes larger than the diameter of the upper part toward the lower side, or the diameter of the lower part may be larger than the diameter of the upper part so that a large amount of water is located close to the ceramic ball 320. there is.

Preferably, the filtering through hole 511 is formed over the entire area of the filter housing 510 . This can solve the problem of deterioration in inhalability when a filter is provided in a conventional purified water bottle, but the filter through hole 511 is not sufficiently formed.

The filter housing 510 may be formed such that upper and lower portions are fitted, but is not limited thereto.

An upper portion of the filter housing 510 is formed with a coupling portion 512 inserted into and coupled to the lower portion of the suction portion 420 .

At least one O-ring groove may be formed on an outer circumferential surface of the coupling part 512, and an O-ring 513 may be coupled to the O-ring groove.

The coupling part 512 serves to connect the filter housing 510 and the suction part 420 so as to be in communication with each other, and the contaminated water passes through the filter part 500 to pass purified water into the suction part 420. ) to be provided.
