An air-conditioning garment includes a garment main part that is worn on the upper body of a wearer, and two fans that are attached to a lower part of a back part of a garment main part, and configured to feed outside air into the inside of the garment main part. Each of the two fans includes a fan main body and a case that houses the fan main body and includes two air outlets. The two air outlets are formed so that their blowing directions are restricted to being upward or obliquely upward. The two air outlets are formed in such a manner that their blowing directions have an upwardly-opened V-shape.

A portable temperature regulation device includes a wearing body and first and second main bodies rotatably connected to the wearing body. The first and second main bodies each include a first housing in which a first receiving chamber is formed to receive a first fan therein. The first main body further includes a first air passage in communication with the first receiving chamber, a first air outlet communicating the first air passage and outside, an air inlet in communication with the first receiving chamber. The first and second main bodies are rotatably connected to the wearing body by a rotation structure. When it needs to fold for storage, the first and second main bodies can be rotated to a folded state, so as to reduce the size of the portable temperature regulation device for easy storage by a user.

A body cooling unit which comprises a fan assembly and a pipe assembly detachably connected to each other. The fan assembly comprises a fan driven by a motor, the motor is powered by a battery. The fan, motor and battery are placed in a housing. The housing comprises inlet and outlet ports. The pipe assembly comprises at least one pipe connected to the outer port of the housing. At least one pipe comprises a plurality of openings for transferring the air to user's body.

A personal ventilation device and method include a first duct segment and a second duct segment both held by a support structure that is configured to be mounted on a wearer of the personal ventilation device. The personal ventilation device also includes a first nozzle mounted to the first duct segment and a second nozzle mounted to the second duct segment. The first and second nozzles are configured to be disposed proximate to opposite sides of a face of the wearer and the first nozzle directs airflow from the first duct segment across the face of the wearer to form a control volume for a breathing space of the wearer.

A tabletop laminar flow HEPA filtered air curtain, for use as a bio-safety separation barrier for the personal protection of individuals from a respired aerosol, is provided. The air curtain has a rectangular cabinet. The cabinet is partitioned into a fan housing, in fluid communication, with a HEPA filter box. The fan housing has an air intake. A fan assembly is mounted in the fan housing. The fan assembly has a ducted housing, in fluid communication with the ambient air intake, and a blower. A horizontal HEPA filter is mounted in the filter box so that a blower discharge passes through the HEPA filter, and upwardly and uniformly through an elongated laminar flow nozzle in a top wall of the filter box.

The P.A.C.K is designed to provide the individual with continuous refreshing air during extreme weather. The P.A.C.K mounts a fan pointed upward towards the users' body. The innovative aspect of the P.A.C.K is that it is a “hands free” portable device that allows the user to be active all the while with both hands available for work unlike the existing devices that requires the use of one hand limiting the activity of the user. This is achieved by attaching the unit to the users' pant belt. The P.A.C.K has an element guard that channels the air towards the body.

The present disclosure discloses a ventilation management system for outdoor products, a sleeping bag, and a chair. The ventilation management system for outdoor products comprises a ventilation chamber, a temperature adjustment device, and a mobile power supply. The ventilation chamber is flexible and integrally arranged on the outdoor products, and a side of the ventilation chamber configured to face a human body comprises a plurality of air outlets. The temperature adjustment device comprises a fan and a control module, and the temperature adjustment device is electrically connected to the mobile power supply. The temperature adjustment device is configured to supply cool or warm air to the ventilation chamber, and the cool or warm air is configured to be blown onto the human body via the plurality of air outlets after entering the ventilation chamber. Each of the sleeping bag and the chair comprises the ventilation management system.

A solar fan device a fan member, a motor member, a solar panel member and an alternate power source member. The fan member having an enclosure formed by an attachment of a front cover member and a rear cover member with one or more removable fasteners securing the closure of the enclosure. The enclosure including a plurality of interchangeable fan blades which are arranged around a spindle member positioned in the enclosure. The spindle member is attached to a motor member which causes the plurality of blades to rotate when the motor member turns on. The motor member actuates the rotation motion of the plurality of interchangeable fan blades. The solar panel member powers the motor member. The alternate power source member provides power to the motor member when the solar panel member is not providing power to the motor member.

A flow through photochemistry apparatus and methods of use are disclosed in the present application. One or more reactant materials are passed through a reaction chamber and are exposed to electromagnetic radiation. The reaction chamber has reflective walls arranged to reflect electromagnetic radiation across the volume of the chamber a plurality of times, thereby increasing the probability of the electromagnetic radiation interacting with the reactive materials. The reaction chamber may be used for sterilization and photochemistry applications.

An air cleaner may include a case having a discharge port formed at an upper side and vertically open; a blower fan disposed inside of the case, and blowing air inside the case toward the discharge port; a discharge body disposed on an upper side of the case in which the discharge port is formed, and having a discharge passage that guides the air, blown by the blower fan, toward the discharge port; a discharge guider rotatably disposed on an upper side of the discharge body, and having a plurality of grills bent so as to guide air, flowing upward through the discharge passage, in a radially outward direction; and a motor that rotates the discharge guider disposed on the discharge body.
