The invention relates to the technical field of clothes treatment equipment, and provides a double-phase active substance generating device and clothes treatment equipment. The double-phase active substance generating device comprises a shell, a separator is arranged in the shell, and an inner cavity of the shell is divided into a gas ionization cavity and a liquid ionization cavity by the separator; an electrode structure is arranged in the gas ionization cavity and is used for generating a gas-phase active substance when being electrified; and a piezoelectric material layer is arranged on one side, facing the liquid ionization cavity, of the separator, and is used for being activated to generate voltage to generate a liquid-phase active substance when the electrode structure is electrified. According to the double-phase active substance generating device, the gas-phase active substance and the liquid-phase active substance can be generated at the same time by electrifying the electrode structure, and under the combined action of the gas-phase active substance and the liquid-phase active substance, residual odor on clothes can be removed, bacteria on the clothes can be killed, air in clothes treatment equipment can be cleaned, and peculiar smells in a barrel can be removed.

This invention discloses an indoor air conditioner unit and its control method, as well as an air conditioner. The indoor air conditioner unit includes: a casing, an indoor heat exchanger, a fan, a photoplasma module, a light sensor, a display panel, and a controller. The controller is configured to: in response to a command to activate the air conditioner's sterilization function, acquire the brightness detected by the light sensor; when the brightness is determined to be greater than a preset brightness threshold, control the photoplasma module to execute a first sterilization mode, the first sterilization mode including: controlling the photoplasma module to simultaneously emit positive and negative ions and ultraviolet light, and controlling the fan speed to be adjusted to the maximum speed, and making the execution time of the first sterilization mode reach a first preset time; when the brightness is determined to be less than the preset brightness threshold, control the photoplasma module to execute a second sterilization mode, the second sterilization mode including: controlling the photoplasma module to emit positive and negative ions, and controlling the fan speed to be adjusted to the minimum speed, which can meet the sterilization requirements while avoiding light leakage affecting sleep.

A catheter comprises: a needle (2) that pierces into tissue; and an obturator 3 insertable in an extractable manner relative to the needle, the needle having: a hollow needle body 2a with a sharp distal end portion 2t; and a needle hub 2b supporting a proximal end portion 2e, the interior of the needle body comprising: a single lumen 2p that is continuous from the proximal end portion to the distal end portion; and a closed end portion (2c) that closes the lumen, and that has a circular and continuous contour shape in the shape of an arc.

The application relates to a high-voltage pulse source excited closed package food plasma sterilization device, which comprises a high-voltage pulse source including a multi-stage pulse output circuit for generating bipolar high-voltage pulse output; and a long-gap dielectric barrier discharge electrode device, wherein the bipolar high-voltage pulse is loaded to an upper electrode and a lower electrode to form a long-gap discharge area for placing closed package food. The application combines the multi-stage high-voltage pulse source with the long-gap dielectric barrier discharge structure to form long-gap dielectric barrier discharge in the normal-pressure air environment, the high-voltage pulse electric field can be coupled to the inside of the package bag through the capacitor to ionize and activate the gas in the bag, so that the closed package food can receive low-temperature plasma sterilization treatment without opening the package bag, secondary pollution caused by re-packaging or external contact after sterilization is avoided, and the health safety and preservation effect of the food are improved.
