An air pipe (74) is disposed to cross the heat exchange duct (62) transversely in the exhaust path (64). Heat exchange is performed between a fluid flowing in the exhaust path (64) and a fluid flowing in the air pipe (74). A socket (76) communicating with the air pipe (74) to detachably mount the flavor generation piece (12) is disposed on the outer side surface of the heat-insulating holder (44).

A linear cutting stapler comprises: an upper jaw and a lower jaw (1) capable of closing or opening relative to each other. A staple cartridge (2) is disposed at a distal end of the lower jaw (1). The lower jaw (1) has a U shape, in which a striker (5) and a pushing rod are slidably disposed. The linear cutting stapler further comprises a safety mechanism. The safety mechanism comprises a safety piece (4), and an opening (52) opened on the striker (5) and for receiving the safety piece. The installation or removal of the staple cartridge (2) may drive the safety piece (4) to move in a direction perpendicular to the axis of the lower jaw (1), so that the safety piece (4) is disengaged from or engaged with the opening (52) of the striker (5). The linear cutting stapler has a simple structure, can be easily fabricated, and is safe and reliable.

A linear surgical stapler includes an upper staple cartridge receiving half-section, a lower staple cartridge receiving half-section and a staple cartridge assembly. The staple cartridge assembly includes a cutting groove in which a reciprocating movement cutter is mounted. The cutter includes a bottom surface and a knife blade located at a far end of the cutter. The staple cartridge assembly includes a restricting member mounted therein and an elastic stopper. The elastic stopper abuts against the restricting member when the staple cartridge assembly is in an initial state. The restricting member breaks away from the staple cartridge assembly when the staple cartridge assembly is in a firing complete state, thereby preventing the cutter from sliding towards the far end of the staple cartridge. As a result, misfiring throughout the whole operation of the linear surgical stapler is prevented.

The invention discloses a linear type suturing and excising device, comprising a body, a staple cartridge rack, a staple anvil, a staple cartridge, a cocking block and a knife pushing rod, wherein the staple cartridge rack, the staple anvil and the staple cartridge are arranged at the far end of the body, the cocking block is used for pushing a staple pushing piece and is arranged in a chute of the staple cartridge, the knife pushing rod pushes the cocking block to move, the staple cartridge rack is provided with a safety block for preventing secondary cocking, the safety block has a linear motion trail, the moving direction of the safety block is vertical to the moving direction of the knife pushing rod, and the safety block is arranged at the far end of the knife pushing rod and the excising knife, and is used for limiting the movement of the knife pushing rod and the excising knife from the near end of the linear suturing and excising device to the far end of the linear suturing and excising device when the linear type suturing and excising device is under the initial state and under the state of cocking completion. The linear type suturing and excising device has the beneficial effects that a doctor is effectively prevented from performing the next operation under the condition of not replacing a cocked staple cartridge, the occurrence of medical negligence is avoided, and the structure is simple and effective.

An atomizing electronic cigarette has an atomizing core component and a liquid storage component, including an electric heater. The electric heater may have a through hole aligned with a channel passing through the liquid storage component. the cigarette can heat and uniformly vaporize liquid from the liquid storage component, with the user inhaling the vaporized liquid. The vapor generated by the atomizing process may be cooled as it flows through the channel.

A work holding mechanism for horizontally holding a flat work is incorporated in work transport equipment. The holding mechanism includes a base member for supporting the work and a plurality of guide members provided at the base member. Each guide member includes a shaft, a contact portion and a limit portion. The shaft is pivotally supported by the base member. The contact portion comes into contact with part of the lower surface of the perimeter of the work and is pushed down, with the shaft as a fulcrum, when the work is placed on the base member. The limit portion is raised, with the shaft as a fulcrum, to face part of the side surface of the perimeter of the work when the contact portion is lowered.

An electrically heated smoking system includes a shell and a replaceable mouthpiece. The shell includes an electric power supply and electric circuitry. The mouthpiece includes a liquid storage portion and a capillary wick having a first end and a second end. The first end of the wick extends into the liquid storage portion for contact with liquid therein. The mouthpiece also includes a heating element for heating the second end of the capillary wick, an air outlet, and an aerosol forming chamber between the second end of the capillary wick and the air outlet. When the shell and mouthpiece are engaged or connected, the heating element is in electrical connection with the power supply via the circuitry, and a flowpath for air is defined from at least one air inlet to the air outlet via the aerosol forming chamber. In use, liquid is transferred from the liquid storage portion towards the heating element by capillary action in the wick. Liquid at the second end of the capillary wick is vaporized by the heating element. The supersaturated vapor created, is mixed and carried in the air flow from the at least one air inlet to the aerosol forming chamber. In the aerosol forming chamber, the vapor condenses to form an aerosol, which is carried towards the air outlet.
