In addition, all connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality Situation is applied, by adding or reducing connection auxiliary, Lai Zucheng more preferably connection structure.Each technology in the utility model is special Sign, can be with combination of interactions under the premise of not conflicting conflict.

If a kind of microbubble of Fig. 1, Fig. 4 obtains device, including the first noumenon 1, inlet channel 2, water outlet is arranged in the first noumenon 1 Road, the swirl chamber 3 that inlet channel 2 is connected to water outlet, the air intake duct 11 for being connected to swirl chamber 3, water outlet, which is provided with, generates micro- gas The structure of bubble.Center line is respectively 3 axis of 2 axis of inlet channel and swirl chamber in Fig. 1.

Air intake duct 11 can connect compressor and air pump etc., in turn, air is pressed into swirl chamber 3 using external impetus.When So, the negative pressure that air intake duct 11 also can use water flowing generation is drawn air into.

For swirl chamber 3, the first noumenon 1 is provided with the first side wall 3b for being used to form swirl chamber 3 and the first bottom wall 3a, the The inlet opening 12a of one side wall 3b setting connection swirl chamber 3, the direction of inlet opening 12a deviates the center of swirl chamber 3, so that water Vortex flow is generated after flowing through inlet opening 12a.

Inlet channel 2 is generally arranged on the first bottom wall 3a, and air intake duct 11 includes along the first of the setting of 3 axis direction of swirl chamber The second air flue that air flue, edge are arranged perpendicular to 3 axis direction of swirl chamber, the first air flue are connected to the second air flue, and the first air flue connects The logical external world, the second air flue are connected to swirl chamber 3, facilitate manufacture, moreover, not influencing microbubble obtains installing and using for device.

For the first noumenon 1, the first noumenon 1 can be equipped with or integrally formed manufacture in one end close to inlet channel 2 There is connector, allows microbubble to obtain device and be fixed on tap.

Certainly, the first noumenon 1 also may be mounted in water pipe, and the first noumenon 1 and water pipe are sealed by sealing ring, so that water Inlet channel 2 is flowed into, is then flowed out via swirl chamber 3 and water outlet.At this time, inlet channel 2 can be water pipe close to the first noumenon 1 water way portion can be omitted inlet channel 2 on the first noumenon 1.

Conventional, the axis of swirl chamber 3 is overlapped with the axis of inlet channel 2, subsequent abbreviation be positive the swirl chamber 3 set or The turbulent structure just set, this results in microbubble to obtain the narrow cyclic annular water inlet 12 that device is provided with, hinders the flowing of water, Lead to inspiratory dyspnea, and the diameter that the size for increasing cyclic annular water inlet 12 also makes microbubble obtain device increases, it is difficult to it is applicable in In conventional water pipe specification.

Certainly, the discussion of the beneficial effect and disadvantage here in relation to the turbulent structure just set and biased, has no effect on and just sets Or biasing turbulent structure and after progressive perforation formula dispersion and fining structure hereafter combination, that is to say, that just setting or biasing Turbulent structure is can to combine to form microbubble acquisition device with progressive perforation formula dispersion and fining structure hereafter.

To solve the problems, such as brought by the swirl chamber 3 just set, as shown in Figure 1 and Figure 2, can make the axis of swirl chamber 3 with The axis bias of inlet channel 2 is arranged, and swirl chamber 3 is provided with the water inlet 12 of connection inlet channel 2, and water inlet 12 is set to inlet channel 2 axis are backwards to 3 axis side of swirl chamber, that is, using offset scroll structure.

The microbubble of the present embodiment obtains device by the way that the axis of swirl chamber 3 and the axis bias of inlet channel 2 is arranged, and makes Water inlet 12 is set to 2 axis of inlet channel backwards to 3 axis side of swirl chamber, so that the water inlet 12 of connection swirl chamber 3 is by narrow Ring-type become crescent shape or column, so that water flow be avoided to pass through from narrow gap, thus the radial ruler of water flow can be increased It is very little, resistance to water-flow is reduced, water flow is facilitated to flow into swirl chamber 3, this diameter for allowing for microbubble acquisition device does not increase, even It can reduce, therefore, microbubble obtains device and can minimize, and is easily connected on water pipe or is arranged inside water pipe, has There is good versatility.

For good beneficial effect caused by further instruction the present embodiment, detailed discussion is now carried out.

The pipeline mainstream caliber of household water mainly has two kinds of models of outer diameter 28mm and outer diameter 22mm at present, with outer diameter 28mm Pipeline for, if bubble generator to be made into it is built-in if, its outer diameter is just required no more than 24.5mm.This is to say, water inlet 12 can only be arranged in a width no more than 2.5mm annular region in, this allow for into The area at the mouth of a river 12 is smaller, alternatively, the outer profile length of water inlet 12 increases compared with the water inlet 12 of conventional circular hole, Water flow is flowed and generates obstruction, therefore, causes back pressure to increase severely and influences the inspiratory effects of vortex, or even also will cause pipeline stream Amount declines to a great extent.

Thus, existing 3 structure of positively fixed type swirl chamber is difficult built-in within the pipeline of 28mm caliber.

Sharp contrast is generated with existing design, the utility model is using the swirl chamber 3 biased.Since swirl chamber 3 is inclined It sets, axis and 2 axis bias of inlet channel one distance, this distance of swirl chamber 3 allow water inlet 12 that can be arranged in one In the region of crescent shape, the semidiameter of 3mm to 4mm is obtained, water inlet 12 can be from narrow strip to ellipse or round It is close, the outer profile length of water inlet 12 is reduced, facilitates water flow by water inlet 12, without increasing the outer of the first noumenon 1 Diameter, in other words, the swirl chamber 3 of biasing can make the volume of microbubble acquisition device and occupied space become smaller, and be convenient for It is built in household water pipe.

As shown in figure 3, as Fig. 1 microbubble obtain device alternative solution, can make swirl chamber 3 several, intake The quantity of the quantity and swirl chamber 3 of mouth 12 is correspondingly arranged.That is, by the way that large eddy chamber 3 is altered to multiple small swirl chambers 3, into And the water inlet 12 of multiple circular holes is formed, it can vary in the narrow situation of water inlet 12.

The further expansion of device is obtained as microbubble, the first noumenon 1 is provided with the line part 14 that lid closes swirl chamber 3, The apopore 13 for being connected to swirl chamber 3 with water outlet is arranged in line part 14, and the cross-sectional area of apopore 13 is reduced along water (flow) direction, Allow to air and water is sufficiently mixed generation bubble.In addition, the cross-section variation of apopore 13 can also produce water flow Raw acceleration, compression bubble and promotion bubble breaking.

For simplify manufacture, can make the outer profile of line part 14 matched with water outlet be arranged namely line part 14 be independent Manufacture, do not increase the manufacture difficulty of vortex cavity.

It is of course also possible to keep line part 14 and the first side wall 3b integrally manufactured, but manufactures and need to improve, the first bottom Wall 3a and the first side wall 3b need separately manufacturing.

Smoothly to make water generate vortex flow, the direction of inlet opening 12a can be made along the tangentially-arranged of swirl chamber 3.

To avoid the aperture of inlet opening 12a limited and then water flow being caused to reduce, the quantity of inlet opening 12a can be made There are two, namely it is provided with pair inlet opening 12b, so that the gross area of inlet opening 12a does not reduce or increases.
