An atomizer having an atomizer head configured to atomize a first fluid. The atomizer includes, in addition, a measurement module including at least one sensor configured to measure the values of at least one parameter of the atomizer, an electronic control module configured to receive the measured values, and a power supply configured to electrically supply the control module with a power supply voltage.

The present disclosure provides an atomization apparatus, which relates to the field of aromatherapy equipment. The atomization apparatus may include a body having an internal cavity, a reservoir chamber disposed in the internal cavity, a spacer disposed above the reservoir chamber, and an oil cup. The spacer and a top wall of the internal cavity may form an atomized gas passage. The atomized gas passage may be communicated with a nozzle of the body. The oil cup may be disposed inside the reservoir chamber and located outside a projection of the spacer onto the reservoir chamber. A bottom of the oil cup may be communicated with the reservoir chamber.

An apparatus for dispensing a frozen confection includes a mixing chamber within which an ice cream and at least one flavored concentrate are mixed. A valve assembly is operable to control a flow of the mixture of ice cream into the mixing chamber. A pump provides said at least one flavored concentrate to the mixing chamber. A dispensing nozzle is arranged in fluid communication with the mixing chamber. The dispensing nozzle has a flow channel through which a mixture of the ice cream and at least one flavored concentrate is dispensed. The flow channel has a first diameter adjacent an inlet end of the dispensing nozzle and a second diameter adjacent an outlet end of the dispensing nozzle. The second diameter is greater than the first diameter.

A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.

A falling-water muffling device for an atomizer. The falling-water muffling device at least includes a falling-water receiving structure, wherein the falling-water receiving structure includes a sidewall and a water mist flow hole surrounded by the sidewall. The internal side of the sidewall forms a receiving surface configured to receive water droplets passing through the water mist flow hole, and a first air inlet is disposed on the sidewall.

An essential oil reflux-type atomizer comprising the following structures: chassis (10), housing (30), atomization chamber (310), gas pump (21), gas tube (22), gas nozzle (23), oil nozzle (24), filter atomization mechanism (40). The filter atomization mechanism (40) is installed in the housing (30) and has a plurality of filter housings (41). A lower end of each of the filter housings (40) has one or more through holes (411). When the gas nozzle (23) ejects an airflow, the airflow draws out the essential oil through the oil nozzle (24) to form a mixed airflow which passes through each of the filter housings (41) successively. Larger essential oil droplets in the airflow are filtered by each of the filter housings (41) to be recycled, while the atomized essential oil gas will pass through the through holes (411) of each of the filter housings to be dispensed. At the same time, the essential oil droplets in the through holes (411) are re-atomized by the airflow to improve the atomization performance. The atomization chamber (310) comprises a guide board guiding the airflow from the gas nozzle (23) upwards towards the filter atomization mechanism (40).

A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas-liquid spout portion, a gas introduction portion, a liquid inlet, a first gas inlet passage, a second gas inlet passage, and a spout. The first gas inlet passage is provided at at least one place of the annular gas introduction portion so as to communicate with the gas flow passage and the gas-liquid mixer, and allows a gas flow flowing through the gas flow passage to enter the gas-liquid mixer. The second gas inlet passage has a gas inlet having a predetermined area ratio, is provided on a downstream side of the first gas inlet passage of the gas introduction portion, and communicates with the gas flow passage and the gas-liquid mixer.

Exemplary air amplifiers described herein can utilize a high-pressure stream of gas to accelerate a low-velocity stream of gas to provide a high-velocity, high-volume stream of gas. This high-velocity, high-volume stream of gas can generate unwanted noise as the high-velocity, high-volume stream of gas propagates through the air amplifier. The exemplary air amplifiers described herein can passively and/or actively suppress, for example, diminish, re-tune, or even completely cancel, the unwanted noise as the high-velocity, high-volume stream of gas propagates through these exemplary air amplifiers. The exemplary air amplifiers described herein can include one or more absorption materials to passively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The exemplary air amplifiers described herein can generate multiple noise suppression waves to actively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The multiple noise suppression waves can destructively combine with the unwanted noise generated by the high-velocity, high-volume stream of gas to suppress the unwanted noise.

A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas introduction portion, a gas-liquid spout portion, a liquid inlet, a gas inlet, a tubular flow passage, a spout, a flow passage having a taper, a straightener, and a projection portion. The liquid inlet allows a liquid flow to enter a gas-liquid mixer which is a space inside the annular gas introduction portion. The gas inlet allows a gas flow to enter the gas-liquid mixer. The straightener has an opening having an uneven shape provided in the flow passage having the taper. The projection portion is provided in the liquid introduction portion, protrudes to the gas-liquid mixer, and forms the straightener and a straightening outlet.
