The inclination angle of the upper wall 14 of the head body 1 for forming the bubble generation space 13 is not limited, and for example, in one embodiment of the bubble jet head, the inclination angle of the upper wall 14 of the head body 1 for forming the bubble generation space 13 is in the range of 0 to 70, preferably 10 to 45.

Preferably, the upper wall 14 of the head main body 1 for forming the bubble generation space 13 has a groove structure, so that not only the entire area of the upper wall 14 can be effectively increased, but also the upper wall 14 can crush bubbles in a gas-liquid mixture in a manner of cutting bubbles after the liquid entering the bubble generation space 13 from the second channel 12 of the head main body 1 can impact the gas-liquid mixture entering the bubble generation space 13 from the first channel 11 to the upper wall 14, thereby facilitating the formation of micro-bubbles.

Preferably, the gas-liquid mixing device 2 is fixedly installed to the head main body 1 so that the gas-liquid mixture discharged from the mixing outlet 201 of the gas-liquid mixing device 2 can directly enter the bubble generation space 13 through the first passage 11 of the head main body 1, and alternatively, the mixing outlet 201 of the gas-liquid mixing device 2 may be communicated with the first passage 11 of the head main body 1 through a connection pipe (e.g., a hose).

Further, the gas-liquid mixing device 2 has a liquid inlet 202, at least one gas inlet 203 and a mixing cavity 204, the mixing outlet 201 and the liquid inlet 202 are respectively communicated with the mixing cavity 204 at two opposite ends of the mixing cavity 204, the gas inlet 203 is communicated with the mixing cavity 204 at the side of the mixing cavity 204, and the diameter of the mixing cavity 204 is larger than that of the liquid inlet 202. When the liquid flows through the mixing chamber 204 from the liquid inlet 202 of the gas-liquid mixing device 2 at a certain speed, a negative pressure environment can be formed in the mixing chamber 204, so that the external gas can automatically enter the mixing chamber 204 from the gas inlet 203 to be mixed with the liquid flowing through the mixing chamber 204 in the mixing chamber 204 based on the principle of atmospheric pressure, thereby forming a gas-liquid mixture and being discharged through the mixing outlet 201.

In other words, in the present invention, the diameter of the mixing cavity 204 of the gas-liquid mixing device 2 is larger than the diameter of the liquid inlet 202, so that a negative pressure environment can be formed in the mixing cavity 204 when the liquid flows through the mixing cavity 204 from the liquid inlet 202 at a certain speed, and thus the external gas can automatically enter the mixing cavity 204 under the passive (e.g. not required to be pumped) condition, thereby being beneficial to reducing the manufacturing cost and the using cost of the bubble spraying head.

Preferably, the inner wall of the inner channel section 212 of the inlet channel 21 is an inclined inner wall to facilitate the flow of liquid from the outer channel section 211 to the inner channel section 212 and through the inlet 202 into the mixing chamber 204.

The first pump device 3 is used for pumping the liquid from the liquid inlet 202 of the gas-liquid mixing device 2 into the mixing chamber 204 to allow the liquid to flow through the mixing chamber 204, because the diameter of the liquid inlet 202 is smaller than the diameter of the channel outer section 211 of the liquid inlet channel 21, so that when the liquid flows from the channel outer section 211 of the liquid inlet channel 21 to the channel inner section 212 and enters the mixing chamber 204 through the liquid inlet 202, the flow rate of the liquid can be increased to facilitate the formation of a negative pressure environment in the mixing chamber 204, and external gas can automatically enter the mixing chamber 204 from the gas inlet 203 to be mixed with the liquid flowing through the mixing chamber 204 in the mixing chamber 204 based on the principle of atmospheric pressure, so as to form a gas-liquid mixture and be discharged through the mixing outlet 201, and then the gas-liquid mixture enters the bubble generation space 13 from the first channel 11 of the nozzle body 1. Meanwhile, the second pump device 4 is used for pumping the liquid from the second passage 12 of the head main body 1 into the bubble generation space 13 of the head main body 1, and the liquid entering the bubble generation space 13 from the second passage 12 of the head main body 1 can impact the gas-liquid mixture entering the bubble generation space 13 from the first passage 11 to the upper wall 14 so that bubbles in the gas-liquid mixture are crushed to form micro-bubbles.
