[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] The following descriptions of the various embodiments are made with reference to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented. Directional terms mentioned in the present invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," and "side," are merely references to the directions in the accompanying drawings. Therefore, the directional terms used are intended to illustrate and understand the present application, rather than to limit the present application. In addition, in the specification, unless expressly described to the contrary, the word "include" or "comprising" should be understood to mean including the element, but not excluding any other elements.

[0030] like Figure 1 The ozone water mixing device shown mainly includes a static mixer 1, a pure water input component 2, an ozone input component 3, an ozone water output exhaust component 4 and a foaming head 5.

[0031] The static mixer 1 can be a conventional one, such as the Frison ozone water static mixer or the one disclosed in Chinese invention patent application number 202111302080.2. A pure water input assembly 2 is connected to the static mixer 1 and is used to deliver pure water (ensuring that the pure water pressure within the static mixer 1 is ≤4.0 bar). An ozone input assembly 3 is also connected to the static mixer 1 (typically in parallel with the pure water input assembly 2) and is used to deliver ozone (ensuring that the ozone pressure within the static mixer 1 is ≥2.5 bar, but the pure water pressure is lower than the ozone pressure). This allows the ozone and pure water to be thoroughly mixed within the static mixer 1, producing pure water containing a high concentration of ozone. The ozone water output and exhaust assembly 4 includes at least a reservoir 40 connected to the static mixer 1 for storing the pure water containing a high concentration of ozone. The foaming head 5 is connected to the liquid reservoir 40, and is used to receive the aforementioned pure water containing high concentration of ozone and generate bubbles therein to form bubble water containing ozone (i.e., output bubble water containing ozone); an infusion pump 50 is preferably installed between the foaming head 5 and the liquid reservoir 40 to ensure the pressure of the delivery of the ozone-containing pure water.

[0032] In this embodiment, the pure water input assembly 2 includes a water pipe 21 connected to the static mixer 1, a first water pump 22 mounted on the water pipe 21, and a first control valve 23 mounted on the water pipe 21 and located between the static mixer 1 and the first water pump 22. The ozone input assembly 3 includes an ozone generating unit 33, an ozone delivery pipe 31 connecting the ozone generating unit 33 and the static mixer 1, and a one-way valve 32 mounted on the ozone delivery pipe 31. The ozone generating unit 33 can be a commercially available one (such as the one disclosed in Chinese Utility Model Application No. 2020232443451 or FQ-301 AC220V). The ozone water output exhaust assembly 40 also includes an external discharge pipe 41 connected to the liquid reservoir 40 and an exhaust valve 42 mounted on the external discharge pipe 41. This allows for the timely discharge of ozone released from the pure water to prevent excessive pressure in the liquid reservoir 40.

[0033] In this embodiment, the bubble water output by the foaming head 5 is preferably micro-nano bubble water containing ozone. Specifically, the foaming head 5 includes a liquid inlet module 51, a liquid outlet module 52 and a foaming module 53 that cooperate with each other.

[0034] The liquid inlet module 51 includes a first liquid inlet column 511 and a second liquid inlet column 512 integrally formed on the end surface of the first liquid inlet column 511. The first liquid inlet column 511 is provided with a first channel 5111, the second liquid inlet column 512 is provided with a second channel 5122 and a buffer channel 5120 connected to the second channel 5122 and located between the second channel 5122 and the first channel 5111. The first liquid inlet column 511 is also provided with a channel connecting the first channel 5111 and the buffer channel 5120. The third channel 5113 of the punching channel 5120 gradually decreases in diameter and increases in diameter from the first liquid inlet column 511 to the second liquid inlet column 512 (i.e., in the direction from the first liquid inlet column 511 to the second liquid inlet column 512 on the axis of the foaming head 5). Thus, the center of the liquid inlet module 51 has a structure similar to a Venturi tube, thereby exerting a Venturi effect, thereby increasing the flow rate of the ozone-containing pure water flowing therethrough. The liquid outlet module 52 includes a liquid outlet column 521 sleeved on the second liquid inlet column 512, a receiving chamber 522 disposed within the liquid outlet column 521 and cooperating with the second liquid inlet column 512, and a central microchannel 525 disposed within the liquid outlet column 521 and connected to the receiving chamber 522, which can increase the outlet pressure of the water and prevent the micro-nano bubbles therein from bursting. The bubble module 52 includes a base ring body 531 installed at the end of the second liquid inlet column 512 and accommodated in the accommodating cavity 522, a bubble cone 532 formed on the end surface of the base ring body 531 and inserted into the second liquid inlet column 512 (a flow channel is formed between the bubble cone 532 and the second channel 5122), and at least one through hole 535 opened on the base ring body 531 and surrounding the bubble cone 532 (in this embodiment, the through holes 535 are three axially symmetrical), so that the ozone-containing pure water with increased flow rate can impact the bubble cone 532 and generate micro-nano bubbles in the water.

[0035] Specifically, the liquid inlet module 51 also includes a first annular groove 5112 defined within the first liquid inlet column 511 and located between the first channel 5111 and the third channel 5113. A second annular groove 5121 is defined on the end surface of the second liquid inlet column 512, and a third annular groove 524 corresponding to the second annular groove 5121 is defined within the liquid outlet column 521. A first protruding ring 533 and a second protruding ring 534 are formed on both end surfaces of the base ring body 531, respectively, to cooperate with the second annular groove 5121 and the third annular groove 524. Sealing rings may also be provided in each of the aforementioned grooves as needed to prevent leakage from the entire foaming head 5. As needed, a fourth annular groove 513 may be defined on the outer surface between the first liquid inlet column 511 and the second liquid inlet column 512, and a fifth annular groove 523 may be defined at the bottom of the accommodating cavity 522.

[0036] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
