Background At present, the household or commercial water purifier has the functions of filtering, purifying, removing chlorine, heating and the like, and can effectively remove fine silt, heavy metal, bacteria, residual chlorine and the like in tap water. Hydrogen-rich water, also known as "hydrogen molecular water," which dissolves hydrogen molecules, and drinking hydrogen-rich water can have a positive impact on human health. Under the condition of normal temperature and normal pressure, the mass solubility of hydrogen in water is about 1.6ppm (converted into volume ratio solubility of 1.83%), which belongs to the gas which is indissolvable in water, and the dissolution of hydrogen in water can be ensured by adopting effective means. As disclosed in chinese patent No. CN111792718B, a hydrogen-rich water generator and a method for generating hydrogen based on a sustainable hydrogen production device are disclosed, wherein the hydrogen-rich water generator is a closed container, and is provided with an air inlet pipe, an water inlet pipe and a water outlet, a second opening is arranged at the upper part of one side of the hydrogen-rich water generator, and the second opening is connected with a feeding pipe, and the feeding pipe is used for adding water when the air in the hydrogen-rich water generator is emptied. The side wall of the hydrogen-rich water generator is provided with a third opening, the third opening is communicated with the second opening through a pipeline, the pipeline is provided with a circulating pump, gas is pumped out of the second opening of the hydrogen-rich water generator and enters the pipeline, the gas returns to the hydrogen-rich water generator from the third opening, and the gas is used for disturbing water in the hydrogen-rich water generator in a bubbling mode, so that the concentration of the hydrogen-rich water is increased. In addition, as disclosed in chinese patent No. CN219652781U, a hydrogen-rich water generating apparatus is disclosed, which includes a hydrogen generating assembly for electrolyzing water to prepare hydrogen, one end of the hydrogen generating assembly is connected to a water supplying assembly for supplying water, the other end of the hydrogen generating assembly is connected to the water generating assembly, the water generating assembly includes a hydrogen mixing structure and a hydrogen reflux structure, the hydrogen mixing structure is connected to a hydrogen outlet of the hydrogen generating assembly, the hydrogen reflux structure is installed on the hydrogen mixing structure, and a hydrogen inlet of the hydrogen mixing structure is communicated with the inside of the hydrogen mixing structure through the hydrogen reflux structure. The hydrogen reflux structure can mix hydrogen with water in a circulating and reciprocating way, so that the contact time of the hydrogen and the water is effectively prolonged. The hydrogen-rich water generating device is characterized in that hydrogen is introduced into water in a large bubble mode, the contact area between the hydrogen and the water is limited, and the dissolution rate is low. In order to solve the problem, the prior art adopts a micro-nano bubble generating device to mix gas and water and then input the mixture into a dissolved air tank, so that the gas is dissolved in the water, and then the dissolved gas is released at high speed through a gas releasing device, so as to generate micro-nano bubbles with micro-nano size and nano-size. In the micro-nano bubbles, hydrogen is wrapped by a surface water film, and the dissolution rate can be increased through molecular dissolution of the micro-nano bubble water film and water. However, if hydrogen is introduced into the micro-nano bubble water, the micro-nano bubbles are directly brought into a circulation loop. At the moment, the micro-nano bubbles are still in a bubble form (non-free gas state) of water film wrapping hydrogen, the internal pressure of the micro-nano bubbles is low after once dissolution, the mass transfer driving force is weak, and the micro-nano bubbles are difficult to be further dissolved after being circularly added into water. Therefore, there is a need for a hydrogen-rich water machine that can improve the dissolution efficiency of hydrogen in water while ensuring the dissolution rate. Disclosure of Invention The technical problem to be solved by the invention is that when hydrogen is introduced into micro-nano bubble water, micro-nano bubbles are directly brought into a circulation loop, the micro-nano bubbles have low internal pressure after once dissolution, the mass transfer driving force is weak, the micro-nano bubbles are difficult to be further dissolved after being circularly introduced into the water, and the dissolution rate can not be ensured and the dissolution
