Embodiment Construction

[0029] From figure 1 The blower filter system 2 carried by a person can be seen in the figure. The blower filter system 2 preferably comprises a large number of components. The components are, for example, blower filter device 4 , battery 14 , air filter 16 , carrying system 18 , breathing mask 20 and / or hose 24 . The air volume flow is generated by means of the blower filter device 4 . from the combination figure 2 It can be seen from the overview that the blower filter device 4 has a blower 6 . The blower 6 preferably comprises a motor, a fan wheel 38 driven by the motor and an associated blower housing 40 , in particular a screw housing. The motor of the blower 6 is generally an electric motor. The energy required to generate the air volume flow is provided by the battery 14 . Due to the ultimate storage capacity of electrical energy of the battery 14, the battery 14 can be replaced. For this purpose, the blower filter device 4 has a battery receptacle 8 into wh...

Abstract

A blower filter system (2) has a blower filter device (4) with a housing (56), an air inlet (50), an air outlet (52) and an air duct (54) extending between the air inlet (50) and the air outlet (52) in the housing (56). A blower (6), associated with the air duct (54), delivers air from the air inlet (50) to the air outlet (52). An air filter (16) and a carrying system (18) can be connected to the blower filter device (4). A tube (24) extends from the air outlet (52) to a breathing mask (20). A sound emission unit (64) is associated with the blower filter device (4). A wall section (58) of the air duct (54) is formed by an acoustic membrane (60) for coupling sound into the air duct (54). The sound emission unit (64) is arranged in the housing (56) of the blower filter device (4).

Description

technical field [0001] The invention relates to a blower filter system (Gebläsefltersystem), comprising: a blower filter device with a housing, an air inlet, an air outlet and an air channel extending in the housing between the air inlet and the air outlet; Blower belonging to the air channel for conveying air from the air inlet to the air outlet; air filter; carrying system (Tragesystem), which can be connected to the blower filter device; breathing mask; hose, which extends from the air outlet to the breathing air mask; and the sound unit (Schallausgabeeinheit) attached to the blower filter. Background technique [0002] In principle, blower filter systems are known from the prior art. Blower filtration systems are typically used for light to moderate respiratory protection. It supports the user of the breathing mask, also known as breathing protection mask, by reducing the breathing resistance compared to conventional breathing masks. A breathing mask is understood to ...
