Electrical device for evaporating of active substances, preferably insecticides

Claim 2

An electrical device for evaporating active substances, such as insecticides, contained in carrier tablets, said device comprising: a housing having a drum; a heater received by said housing disposed peripherally of said drum; a protective grating spaced from and covering at least a part of said heater; a drum magazine located on said housing for storing a plurality of the carrier tablets in a storage position located peripherally of said drum, said drum magazine being relatively rotatable with respect to said heater such that a stored carrier tablet can be transported by said relative rotation from the storage position and can be suitably introduced into the space between said heater and said protective grating.

Claim 3

A device according to claim 1, characterized in that said drum magazine is formed as a cage rotatably guided in a ring-shaped interspace of a double-walled housing and is provided with a plurality of pockets for receiving the carrier tablets; and that protective grate is disposed on one wall and the heater is disposed on the other wall of said housing.

Claim 4

A device according to claim 2, characterized in that said cage is provided with break-outs between said pockets which, in such rotary-angular positions of said cage in which a pocket is provided between said heater and protective grating, are in alignment with a pair of breakouts in the housing walls.

Claim 5

A device according to claim 2, characterized in that, in such rotary-angular positions in which a pocket is provided between said heater and said protective grating, said cage and housing walls circumferentially, tightly seal the remaining pockets.

Claim 6

A device according to claim 2, characterized in that said cage is axially extractable from said housing at least to such an extent as to permit introduction of carrier tablets into the pockets.

Claim 7

A device according to claim 5, characterized in that said cage is extractable from housing only in such rotary-angular positions in which none of the pockets is located between said heater and said protective grating.

Claim 8

An electrical device for evaporating active substances, such as insecticides, contained in carrier tablets, said device comprising: a housing provided with a magazine that is a pot-shaped container in which carrier tablets when stored therein in a storage position are flatly in abutment with one another; a heating panel received by said housing; a protective grating spaced from said heating panel such that carrier tablets can be introduced therebetween; a transporting member movably located on said housing and provided with an inner pocket for receiving a carrier tablet, said pocket displaceable between said magazine and said heating panel so as to place permanently a received carrier tablet, through the movement of said transporting member from said storage position into said space between said heating panel and protective grating, in communication with the outer atmosphere via the protective grating; a pot-shaped waste box into which a tablet entrained in said pocket can be deposited, said pocket being further movable from said magazine past said heating panel to said waste box; and spring pressure means for urging carrier tables when stored in said container toward said transporting member.

Claim 9

An electrical device for evaporating active substances, such as insecticides, contained in carrier tablets, said device comprising: a housing provided with a magazine that is a pot-shaped container in which carrier tablets when stored therein in a storage position are flatly in abutment with one another; a heating panel received by said housing; a protective grating spaced from said heating panel such that carrier tablets can be introduced therebetween; a transporting member movably located on said housing and provided with an inner pocket for receiving a carrier tablet, said pocket displaceable between said magazine and said heating panel so as to place permanently a received carrier tablet, through the movement of said transporting member from said storage position into said space between said heating panel and protective grating, in communication with the outer atmosphere via the protective grating; a pot-shaped waste box into which a tablet entrained in said pocket can be deposited, said pocket being further movable from said magazine past said heating panel to said waste box; and spring pressure means for urging carrier tables when stored in said container toward said transporting member.

Claim 10

A device as claimed in claim 7 wherein said tablet is deposited in said waste box by gravity.

Claim 11

A device as claimed in claim 7 wherein said tablet is deposited in said waste box by spring force.

Claim 12

A device as claimed in claim 9 wherein said table is also deposited in said waste box by gravity.

Claim 13

A device as claimed in claim 7, characterized in that said transporting member is a disc rotatably disposed on said housing.

Claim 14

A device as claimed in claim 7 characterized in that said transporting member is a slide displaceably guided for reciprocating motion on said housing.

Claim 15

An electrical device for evaporating active substances, such as insecticides, contained in carrier tablets, said device comprising: a housing provided with a magazine that is a pot-shaped container in which carrier tablets when stored therein in a storage position are flatly in abutment with one another; a heating panel received by said housing; a protective grating spaced from said heating panel such that carrier tablets can be introduced therebetween; a transporting member movably located on said housing and provided with an inner pocket for receiving a carrier tablet, said pocket displaceable between said magazine and said heating panel so as to place permanently a received carrier tablet, through the movement of said pocket into said space between said heating panel and protective grating, in communication with the outer atmosphere via the protective grating; a pot-shaped waste box into which a carrier tablet entrained in said pocket can be deposited, said pocket being movable from said magazine via a switch past said waste box to said heating panel, and upon backward movement, the entrained carrier tablet can be guided into said waste box through said switch; and spring pressure means for urging carrier tablets when stored in said container toward said transporting member.

Claim 16

An electrical device for evaporating active substances, such as insecticides, contained in carrier tablets, said device comprising: a housing provided with a magazine that is a pot-shaped container in which carrier tablets when stored therein in a storage position are flatly in abutment with one another; a heating panel received by said housing; a protective grating spaced from said heating panel such that carrier tablets can be introduced therebetween; a transporting member movably located on said housing and provided with an inner pocket for receiving a carrier tablet, said pocket displaceable between said magazine and said heating panel so as to place permanently a received carrier tablet, through the movement of said pocket into said space between said heating panel and protective grating, in communication with the outer atmosphere via the protective grating; a pot-shaped waste box into which a carrier tablet entrained in said pocket can be deposited, said pocket being movable from said magazine via a switch past said waste box to said heating panel, and upon backward movement, the entrained carrier tablet can be guided into said waste box through said switch; and spring pressure means for urging carrier tablets when stored in said container toward said transporting member.
