Abstract

The present invention provides a nozzle for forming microbubbles for domestic use to allow water flowing in from a faucet to pass through an accepting space of a housing having a spiral bubble cutting member, wherein bubbles included in the water run into the strings of first and second elements making up the bubble cutting member to be successively divided into micrometers of microbubbles to be discharged.

Description

TECHNICAL FIELD [0001] The present invention relates to a nozzle for generating micro bubbles,

The present invention relates to a home micro-bubble generating nozzle, and more particularly, to a home micro-bubble generating nozzle capable of being installed simply on a faucet, and also capable of passing water introduced from a faucet into a housing space provided with a spiral bubble- Wherein the bubbles collide with the strings of the first and second elements constituting the bubble-cutting member, and the bubbles are subdivided in the order of μm to be discharged.

Conventional micro-bubble generating devices include a method using an impact type or a swirl type nozzle, a method using a micro-pore filter, and the like.

The impact-type nozzle-type micro-bubble generating device simply causes the gas-liquid mixture to collide with the impact plate, and breaks the gaseous gas particles by this action to refine. However, the impact type nozzle system requires a high pressure of 5 to 20 bar, has a large flow loss, requires a large number of nozzles and a bulky mixing tank, and thus has a disadvantage that the structure and equipment of the apparatus are complicated.

Like the impact type nozzle system, the swirl type nozzle type micro bubble generator requires a high pressure and requires a bulky mixing tank because it can not generate minute bubbles in a single nozzle.

Therefore, the impact type nozzle system and the swirl type nozzle type micro bubble generator are complicated in structure and equipment, and thus it is difficult to apply to the general household faucet.

In addition, the conventional micro-bubble generating apparatus of the micro-pore filter method has a disadvantage that the problem of filter clogging occurs and maintenance is troublesome and the efficiency of bubble generation of the apparatus is lowered when the use time is accumulated.

The housing has a lengthwise accommodation space opened front and rear so that water is passed at a certain pressure. In the present embodiment, the housing is divided into first and second bodies (30, 20) . The first and second bodies 30 and 20 may be made of stainless steel, which is preferably excellent in corrosion resistance. Hereinafter, the housing will be described together with the state where the first and second bodies 30 and 20 are engaged.

Referring to FIG. 3, the first body 30 of the housing includes a first support body 33 having a first hollow portion 34 in the front-rear direction; A body coupling portion 31 having a second hollow portion 31a communicating with the first hollow portion 34 and protruding toward the rear of the first support body 33 and having a thread on the outer peripheral surface; And a third hollow portion 32b communicating with the first hollow portion 34 and adapted to be inserted and inserted into the faucet and protruding forward from the first support body 33. The inner peripheral surface of the third hollow portion 32b, A faucet connection part 32 formed with a water supply port 32a; . In addition, the inner diameter of the third hollow portion 32b is preferably formed so as to substantially correspond to the diameter of the domestic faucet used in the present embodiment.

In addition, a watertight packing (not shown) may be further interposed between the third hollow portion 32b and the faucet inserted therein in order to further secure the watertightness.

According to this structure, when the faucet is connected to the third hollow portion 32b and then water is kneaded, the water is introduced into the accommodating space of the housing through the first to third hollow portions 34, 31a and 32b of the first body 30 23).

Referring to FIG. 4, the second body 20 includes a second support body 21 having a receiving space 23 therein; And a hose coupling portion 22 having a fourth hollow portion 22a communicating with the accommodation space 23 and serving as a water discharge portion protruding rearward from the second support body 21. [ At this time, the hose coupling part 22 may be formed with threads such that a coupling member 13 such as a coupling nut provided at one end of the hose 12 is fitted and screwed to the outer peripheral surface. The coupling member 13 may be provided with a watertight packing therein.

According to this structure, the water introduced into the accommodation space 23 is supplied to the hose 12 through the hose engaging part 22 after generating fine bubbles through the bubble cutting member 40 installed in the accommodation space 23, And is discharged through the shower head 11.

In addition, the front side end of the second support body 21 may be formed with a thread 24 on the inner circumferential surface thereof so as to be screwed with the thread of the body coupling portion 31 of the first body 30.

Referring to Figs. 5 and 6, the bubble cutting member 40 is inserted into the receiving space 23 of the housing thus constructed, and has a spiral structure along the longitudinal direction.

Further, the bubble cutting member 40 physically divides the bubbles contained in the water into fine bubbles when the water introduced from the faucet passes through the housing space 23 of the housing.

The bubble cutting member 40 includes a plurality of first and second elements 43 and 45). In this embodiment, since the housing space 23 of the housing is formed in a cylindrical shape, the first and second elements 43 and 45 are formed in semicircular shapes so as to maximize the contact area with the incoming water, It is preferable to form a circle corresponding to the space 23.

The first element 43 is spaced apart along the longitudinal direction of the accommodation space 23 with a predetermined gap 46 therebetween. The second element 45 is spaced apart with a predetermined gap 43 along the longitudinal direction of the accommodation space 23 and connects the two first elements 43 arranged in the forward and backward directions obliquely. Reference numerals 41 and 42 denote connection portions connecting the end portions of the first and second elements 43 and 45 spaced apart from each other in the longitudinal direction.

According to the above-described coupling structure, the bubble cutting member 40 can be formed so that the first and second elements 43 and 45 are alternately connected along the longitudinal direction of the receiving space 23 and spirally formed along the longitudinal direction as a whole. At this time, the bubble cutting member 40 may be formed in a zigzag shape by joining the opposite ends of each second element 45 to the corresponding ends of the two first elements 43 arranged diagonally on the front and rear sides, respectively.

In this embodiment, the structure in which the first and second elements 43 and 45 are connected alternately one by one, that is, the structure in which the second element 45 connects the two front and rear first elements 43 . However, the present invention is not limited thereto. The present invention can be applied to a structure in which at least three first elements, which are arranged at predetermined intervals, As shown in FIG.

The bubble cutting member 40 may adjust the average size of the minute bubbles generated by adjusting the number of the first and second elements 43 and 45 and the distance between the first and second elements 43 and 45 have.

The bubble cutting member 40 having such a structure is configured such that the remaining portion of the bubble cutting member 40 except for the portions connected to each other in the strings of the first or second element 43 or 45 is in contact with water passing through the housing space 43 of the housing The bubbles contained in the water are divided into fragments by splitting the bubbles into fine bubbles.

That is, the water introduced from the faucet swirls spirally along the longitudinal direction of the bubble cutting member 40 in the housing space 43 of the housing, and flows backward, so that the first and second elements 43 and 45 The large bubbles contained in the water are continuously divided into small bubbles and become small bubbles having a particle diameter in the order of micrometers.

At this time, if the total number of the first and second elements 43 and 45 of the bubble cutting member 40 is n, the number of times that one large bubble is divided is 2 ⁿ . For example, if the first and second elements 43 and 45 are constituted by a total of 10, then the number of bubbles to be separated becomes 2 ¹⁰ = 1,024. As a result, the number of minute bubbles increases as the size of the bubbles becomes exponentially smaller according to the number of times that one large bubble passes through the first and second elements 43 and 45 of the bubble cutting member 40.

Also, in this embodiment, the front and rear inner surfaces of the accommodation space 23 to which the first and second bodies 30 and 20 are coupled may be a flat surface. The bubble cutting member 40 may be formed such that the first or second element 43a or 45a located at both ends in the longitudinal direction is flush with the front and rear inner surfaces of the receiving space 23.

If the first or second element 43a or 45a located at both ends in the longitudinal direction is formed to be inclined with respect to the front and rear inner surfaces of the accommodation space 23, the front and rear ends of the bubble cutting member 40, The bubble cutting member 40 may be shaken at the time of inflow of water, so that the stability may be deteriorated and noise may be generated. The first or second element 43a or 45a located at both ends in the longitudinal direction of the bubble cutting member 40 is bent by the water pressure of the inflow water so that the accommodation space 23 is blocked or the bubble cutting member 40 It is possible to cause a problem that the function is not performed.

In this embodiment, the first or second elements 43a and 45a located at both ends in the longitudinal direction are formed to be flat in correspondence with the front and rear inner surfaces of the accommodation space 23, thereby solving the above problem.

In addition, the o-ring 50 may be inserted into the receiving space 23 of the second body 20 before the bubble cutting member 40 is inserted. The O-ring 50 basically improves the watertightness and can reduce the error between the entire length of the bubble cutting member 40 and the internal length of the accommodation space 43. That is, the O-ring 50 minimizes the movement or wobble of the bubble cutting member 40 in the receiving space 43 even if the water pressure is reduced by making the bubble cutting member 45 completely close to the receiving space 43, Can be prevented. At this time, the O-ring may be further disposed on the second hollow portion 31a of the body coupling portion 31 of the first body 30, if necessary.

In addition, a packing 35 may be provided on the outer circumferential surface of the body coupling portion 31 to secure water tightness when the body coupling portion 31 is engaged with the second body 20. The first body 30 is inserted into the receiving space 23 of the first body 20 after the bubble cutting member 40 is inserted and the front end of the bubble cutting member 40 is slightly protruded. The watertightness is ensured by the packing 35, the water pressure in the accommodation space is stably maintained, and the effect of preventing the bubble cutting member 40 from shaking can also be improved.

The household micro-bubble generating nozzle of the present embodiment having the above-described structure is small in size and simple in installation, so that it can be easily applied to domestic faucets. In addition, it includes a spiral bubble cutting member 40 made up of a plurality of elements 43, 45, and the strings of the respective elements 43, 45 are physically cut into bubbles of water introduced from the faucet, , And the bubble generation efficiency is excellent.

Micro-bubbles can generate energy and free radicals from the internal pressure of the bubbles through the self-pressurizing effect, thereby sterilizing various microorganisms such as Escherichia coli or pathogenic bacteria such as food poisoning bacteria, As the specific surface area increases, the electrification effect is increased and the organic matter can be adsorbed electrostatically. The bubble cutting member 40 may be made of, for example, a brass material whose main material is copper. In this case, copper ions (Cu ²⁺ ) are generated by ionization in the water, and thereby sterilizing pathogenic microorganisms Can be further improved.

The domestic micro-bubble generating nozzle of the present embodiment thus configured can be applied to bathroom faucets, faucets in wash basins, faucets in sinks, and the like.
