Apparatuses described herein relate to coniditioning an edge of a substrate using a water jet. In one embodiment, an apparatus includes a nozzle connected on a receiving end with a connecting tube to receive a water jet that is a stream of water accelerated at a high velocity to generate a high pressure for cutting a substrate, where the water jet exits through the nozzle. The appartus further includes a deflector coupled to the nozzle, where the deflector splits the water jet into a cutting stream of water for cutting the substrate and an angled stream of water for conditioning an edge of the substrate.

A dose collection container comprising first and second opposing walls, the first wall comprising an aperture sized to receive a nozzle of a nasal spray, and the second wall comprising at least two diverging impact surfaces which, on actuation of a nasal spray into the dose collection container, deflect the spray along an internal surface. Also included are methods and apparatus for using the described dose collection container.

An irrigation spraying device includes: a tee joint, a ground picket, a spraying head and two quick connectors. The spraying head is disposed at a top portion of the tee joint; the two quick connectors are disposed on two sides of the tee joint respectively; and a top portion of the ground picket is provided with an engaging portion, which includes two clips matched with two ends of the tee joint respectively. The device can achieve spray irrigation through hanging, can adapt to various irrigation scenes, improves its adaptability, and is simple in structure, convenient to operate, and suitable for popularization and application. A setting of the clips enables a rotation of the tee joint to realize angle adjustment of the spraying head, thereby adjusting the angle of the spraying head during ground irrigation, further improving the adaptability of the device to meet needs of various irrigation scenes.

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 fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and a cylindrical outer wall. A circular deflector is mounted to the body, and includes a planar disk having a mounting hole in a center of the planar disk to receive the cylindrical outer wall of the junction, and a plurality of slots on a periphery of the circular planar disk. The plurality of slots includes four radial first slots, four radial second slots, eight radial third slots, and eight fourth slots. The nozzle has a K-factor of at least 28 gpm/(psi).sup.1/2.

Inhalation actuator (6), having a receptacle (5) for receiving a discharge pipe (4) of an inhalant reservoir (1), an inhalant nozzle (9) for spraying inhalant from at least one nozzle outlet opening, an inhalant delivery system (8) for delivering inhalant from the discharge pipe to the inhalant nozzle, a baffle element (10) onto which inhalant can be sprayed in a straight line from the nozzle outlet opening, an aerosol chamber (12) with an internal volume to which inhalant sprayed from the inhalant nozzle can be delivered, wherein the aerosol chamber has an aerosol outlet (11), which has a local narrowing, for dispensing aerosol from the aerosol chamber, and an air delivery system (13) separate from the inhalant nozzle and from the aerosol outlet. Inhalation device having the inhalant reservoir with a pressurized container (2), and having the inhalation actuator, wherein the inhalation actuator does not need to have the local narrowing. Insert (21) for inserting into the mouthpiece (18) of an inhalation actuator, the insert having: centring means for centring the insert in the mouthpiece, a wall (25) which is arranged transversely with respect to the insertion direction and which is arranged upstream of the centring means in the insertion direction, an inhalant inlet opening (24) provided in the wall, a baffle element, which is arranged upstream of the inhalant inlet opening counter to the insertion direction, a surface which is arranged transversely with respect to the insertion direction, next to the baffle element, and though which aerosol can flow freely in the insertion direction, an air inlet (13) arranged upstream of the free-flow surface in the insertion direction, and an aerosol outlet which is arranged upstream of the free-flow surface counter to the insertion direction.

An atomizer for applying a coating includes a nozzle plate, an actuator, and an acoustic focusing device. The nozzle plate defines at least one aperture. The actuator is configured to oscillate to form pressure waves within a fluid to eject the fluid from the nozzle plate. The acoustic focusing device focuses the pressure waves toward the apertures.

A smoke generator for anti-burglar purposes comprising canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further comprises a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape.
