Micro-bubble spray head and washing equipment with same

Abstract

The invention relates to a micro-bubble spray head and washing equipment with the same The micro-bubble spray head comprises an integrated spray pipe and a micro-bubble bubbler fixed to the outlet end of the spray pipe; a diameter-reducing conical channel part is arranged in the spray pipe; at least one stage of diameter-reducing conical channel is formed in the diameter-reducing conical channel part in the water flow direction; a spraying hole is formed in the downstream end of the diameter-reducing conical channel part, and the spraying hole is configured to generate negative pressure in the integrated spraying pipe after water flow pressurized through at least one stage of diameter-reducing conical channel is sprayed out of the spraying hole; an air suction port is formed in the integrated spray pipe and is positioned close to the spraying hole, so that air is sucked into the integrated spray pipe through the air suction port by means of negative pressure and is mixed with the water flow to generate bubble water; and the micro-bubble bubbler comprises at least two stages of filter screens which are spaced by a preset distance along the water flow direction so as to change the bubble water into micro-bubble water. Although the micro-bubble spray head is simple in structure, the micro-bubble spray head has excellent micro-bubble generation performance.

Description

technical field [0001] The invention relates to a micro-bubble generating device, in particular to a micro-bubble spray head and washing equipment with the micro-bubble spray head. Background technique [0002] Micro-bubbles generally refer to tiny bubbles with diameters below 50 micrometers (μm) when bubbles occur. Microbubbles can also be called micro- / nano-bubbles, micro-bubbles or nano-bubbles according to their diameter range. Due to their small buoyancy in the liquid, the microbubbles stay in the liquid for a long time. Also, the microbubbles shrink in the liquid until they eventually break up, creating smaller nanobubbles. During this process, the rising speed of the bubbles becomes slower because they become smaller, resulting in high melting efficiency. Microbubbles locally generate high-pressure and high-temperature heat when they are broken, thereby destroying foreign substances such as organic substances floating in the liquid or attached to objects.

Problems solved by technology

[0007] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the technical problems of the existing micro-bubble generator with complex structure and high manufacturing cost, the present invention provides a micro-bubble spray head, which includes an integrated nozzle pipe and The micro-bubble bubbler fixed on the outlet end of the integrated nozzle is provided with a tapered channel part with a smaller diameter in the integrated nozzle, and the tapered channel part with a smaller diameter is arranged along the water flow direction At least one stage of reduced-diameter tapered passage is formed, and a spray hole is formed on the downstream end of the reduced-diameter tapered passage portion, and the nozzle hole is configured to pass through the at least one stage of reduced-diameter tapered passage. After the pressurized water flow is ejected from the nozzle hole, a negative pressure is generated in the integrated nozzle pipe; an air suction port is arranged on the integrated nozzle pipe, and the air suction port is positioned close to the nozzle hole so that the air is sucked into the integrated spray pipe through the suction port by means of the negative pressure and mixed with the water flow to generate bubble water; and the micro-bubble bubbler includes at least Two-stage filter to convert said sparkling water into micro-bubbled water
