A smoke and dust treatment apparatus for welding, said apparatus comprising a polishing and dust extraction module and a smoke and dust purification module. The polishing and dust extraction module comprises a double-layer dust extraction cover (3), a protective cover (2), an industrial brush (4), a first air guide portion, a second air guide portion (24) and a drive motor (22), the drive motor (22) driving the industrial brush (4) to rotate at high speed to perform polishing. During welding and polishing, a mechanical arm (6) drives the double-layer dust extraction cover (3), and a suction hole (20) of the double-layer dust extraction cover (3) and a suction guide hole (19) on the industrial brush (4) simultaneously take in toxic gas and debris such as iron filings.

A substrate processing device includes: a chamber; a substrate processing mechanism that has a holding member, and discharges a processing fluid onto a substrate held by the holding member; a joint pipe that has a lower opening provided below the holding member, and an upper opening provided above the holding member, and is disposed such that at least part of the joint pipe from the lower opening to the upper opening passes through the outside of the chamber; and an air flow generator that is provided in the joint pipe. The air flow generator circulates an atmosphere in the chamber by discharging the atmosphere in the chamber from the lower opening to the joint pipe to allow the atmosphere to pass through the joint pipe, thereby introducing the atmosphere again into the chamber via the upper opening so that a downflow of the atmosphere occurs in the chamber.

A blow-by gas filtration assembly fluidically connects to a vehicle engine system to receive blow-by gases and filter the suspended particles. A filtration assembly main body includes a filtration chamber and an outlet mouth. A filter group is radially crossable by blow-by gases from outside to inside, including a central cavity. A command group partially houses and supports on the main body operatively connected to the filter group to command the filter group in rotation. A support group supporting the filter group includes a bearing element with an outer fifth wheel sealingly engaging an outlet edge, an inner fifth wheel defining an outlet passage for filtered blow-by gases, and a hollow tubular member defining an outlet duct, including a bearing end operatively connected to the inner fifth wheel and a support portion extending from the bearing end, in the central cavity, mounting the filter group on the support portion.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

An improved isolation ward structure includes a top portion further comprising a space, a fresh-air pipe, a communication pipe and a an exhaust-connected pipe wherein the space is furnished with an air filtration unit (FFU); an end of the communication pipe is communicated with the fresh-air pipe while its other end is communicated with the air filtration unit (FFU), an end of the exhaust-connected pipe is communicated with the fresh-air pipe; a bedroom being positioned under the air filtration unit (FFU) will let the air which is filtered through the air filtration unit (FFU) enter the bedroom; a bottom portion being positioned under the bedroom has a semi-hermetic space formed by the plurality of elevated honeycomb floors; the air within the bedroom will enter the semi-hermetic space which will let the pathogenic air within the bedroom (10) flow therein via the plurality of honeycomb floors (22) and re-circulate through the air filtration unit (FFU) to be filtered; and a backflow circulation portion being positioned above the semi-hermetic space and below the space with its upper end communicates with the other end of the exhaust-connected pipe; the backflow circulation portion is adjacent to the bedroom for re-circulating the air waited to be filtered within the semi-hermetic space to the fresh-air pipe therein.

An electronic cigarette particularly adaptable to vaporize liquid material also having exhale filter function is disclosed herein. The exhale function is useful to prevent second hand smoke in an enclosed environment, for example. An innovative diverter valve assembly comprises a unique duckbill valve configuration diverting air through a cooker chamber and into a mouthpiece in an inhale function and diverting exhaled air around the cooker chamber in the exhale function and through a filter assembly. A preferred embodiment further introduces a unique shape to the smoking instrument being elliptical in the cross-section and tapering to proximal and distal ends.

A gel-sealed air supply box comprising an air inlet and a box body, wherein the box body is internally provided with a filter. A plurality of filter profiles that are sequentially connected are arranged on inner side surfaces of the box body, and a corner dust generating pipe is arranged between two filter profiles of the plurality of filter profiles. A dust distributing pipe is arranged at a top end of the plurality of filter profiles, and the dust distributing pipe is communicated with the corner dust generating pipe. A plurality of dust holes are formed in a top end of the dust distributing pipe. According to the disclosure, dust can be uniformly generated and a more precise detection result can be achieved.

An intelligent robot includes at least one accessory to measure activity and state in proximity to the robot; an air filtration module housed in a casing made of a UV blocking material; and a control center to analyze output of the at least one accessory, to recognize a known target user according to the analysis and to control functionality of said robot and the air filtration module for said known target user according to saved preferences for said known target user.

Disclosed are a modularized dust collector system and a control method thereof. In the system, an air inlet and guide device is in communication with a filter device, and comprises a dust inlet channel, a dust guide plate and an airflow uniform-distribution plate; the filter device comprises a dust collector dust-air box and a dust-removing filter bag, and the filter device is of an integrated drawer-type push-pull structure as a whole; an air outlet device is in communication with the filter device, and the air outlet device comprises a dust collector purified air box and an air outlet channel; an ash-removing device is arranged inside the dust collector purified air box; and an ash collecting device is in communication with the filter device, and the ash collecting device has an upper region being provided with an ash hopper, and a lower region therein being provided with an ash conveying mechanism.
