The domestic cavitation cleaner is simple in structure, safein use, convenient and reliable in operation. The invention aims to provide the domestic cavitation cleaner which can be operated in the room and can perform cavitation cleaning on any corner of the high-altitude outdoor glass surface, and reach the high-efficient cleaning effect; meanwhile, the domestic cavitation cleaner has water saving effect and solves the problem that the personal safety hidden trouble is existed during the traditional manual wiping for a part of body is placed out of high-altitude room.

The invention discloses a strong-shear annular jet cavitation generator, which comprises a high-pressure water supply pipe, a rectifier pipe, a tubular constriction section, a back pressure chamber and an outlet pipe, wherein the tubular constriction section can be further divided into an annular nozzle and a cavitation nozzle. room in two parts. The working fluid enters the rectifier pipe through the high-pressure water supply pipe, and then flows through the annular nozzle. After the pressure energy is converted into kinetic energy, it is ejected at a high speed at the outlet of the annular nozzle and injected into the cavitation chamber. Due to the diffusion of the jet and the hindrance of the back pressure chamber, The backflow of the working fluid occurs, and the backflow meets the high-speed jet in the cavitation chamber to generate a strong shearing effect, which induces severe cavitation. Then the cavitation flow flows through the cavitation chamber and the outlet pipe, the flow velocity decreases, the pressure increases, and the cavitation bubbles collapse under the action of higher pressure, resulting in local high temperature and high pressure, and the formation of shock waves and micro jets. The invention can realize strong shearing action, so that the cavitation intensity is higher and the cavitation effect is better. The invention has no moving parts, simple structure, easy processing and can be used on a large scale.

The invention discloses a cavitation generator with a special-shaped flow channel, which comprises an outer pipe, an inner pipe and a connecting block, the space between the outer pipe and the inner pipe is an annular flow passage, and the center of the inner pipe is a central flow passage; The outer tube and the inner tube form a whole double flow channel through a connecting block, and the whole double flow channel is printed by 3D printing technology; the central flow channel is composed of an inlet section, a tapering section, a holding section and a diverging section Composition, the cross-section of the central channel is an irregular polygon; the annular channel is a stepped channel along the axial direction and consists of two stages of deceleration chambers. The special-shaped flow channel adopted in the present invention can greatly enhance the turbulent flow intensity in the tapered section and the tapered section through exploration. In the tapered section, the fluid will squeeze from the dovetail-shaped part of the flow channel to the square part. Diffuse from the square part of the flow channel to the dovetail part, forming strong turbulence and eddies. The cavitation intensity is significantly enhanced, the required water supply pressure is significantly reduced, and it is more efficient and energy-saving.

The invention relates to an ultrasonic cavitation device, which comprises: a vibration body and a reflector, wherein a radiation surface is arranged at one end of the vibration body, and a liquid thin layer is formed between the radiation surface and the reflection body; the vibration body generates ultrasonic waves and enters through the radiation surface into the liquid thin layer, and form a sound field in the liquid thin layer; the reflector reflects the ultrasonic radiation radiated by the radiation surface, and the sound field in the liquid thin layer is strengthened through multiple reflections and superpositions of the reflector and the radiation surface ultrasonic waves, thereby A large cavitation cloud is formed that spreads laterally along a thin layer of liquid. In the ultrasonic cavitation device provided by the present invention, a reflective surface is arranged on the side of the transducer radiation surface, so that under a small input power, the sound field in the liquid thin layer is strengthened to form a large-area laterally spread cavitation cloud.
