Abstract: An air-liquid exchange element and an aerosol cartridge are disclosed. The air-liquid exchange element comprises an air-liquid exchange element capillary pore axially penetrating through the air-liquid exchange element and an air-liquid exchange element body constituting a peripheral wall of the air-liquid exchange element capillary pore, the air-liquid exchange element body is made by bonding fibers. The air-liquid exchange element according to the present invention is small in size and simple in structure, and is very suitable for using in an aerosol cartridge with a small space.

Abstract: A liquid storage element, a wicking element, a cooling element, a condensate absorbing element, and a supporting element using in an aerosol emission device is disclosed. The aforementioned elements have a three-dimensional network structure formed by thermally bonding bicomponent filaments, the bicomponent filaments have a sheath and a core. The aforementioned elements having a three-dimensional network structure formed by thermally bonding the bicomponent filaments according to the present invention can be conveniently assembled in the aerosol emission device.

Abstract: An aerosol cartridge is disclosed. The aerosol cartridge comprises a liquid storage element and an independent breath element that communicates the liquid storage element with atmosphere, the independent breath element includes an independent breath element core and at least one independent breath element through-hole axially penetrating through the independent breath element. The aerosol cartridge according to the present invention can precisely control the negative pressure in the liquid storage element, so that the liquid can be stably conducted from the liquid storage element, thereby stabilizing the atomization and reducing the risk of liquid leakage.

Abstract: An aerosol cartridge with an air-liquid channel is disclosed. The aerosol cartridge includes: a liquid storage element, an atomizer and an air-liquid channel, the liquid storage element and the atomizer are communicated by the air-liquid channel, the air-liquid channel includes at least one fluid channel axially penetrating the air-liquid channel, and the air-liquid channel further includes a fluid core.

Abstract: This invention refers to a folded trampoline which can be installed easily. It is equipped with tubes aimed at supporting bed surface as well as feet outside the bottom of the tubes. There are folding devices between the tubes and the feet, which consist of exterior folding units, interior folding units, handle, plug pin and reset spring. The exterior folding units which are furnished with locating holes, plus the interior folding units, are connected with tubes, and the feet linked with the inner side of the exterior folding units are articulated with the interior folding units and armed with through-holes which plug pin can go through. This invention has several elastic cords corresponding to fixed units. During installation, one end of the elastic cord will be inserted into the fixed unit, and the other end will go through the ring and the tube successively.
