INTEGRATED CHEMICAL SENSOR FOR DETECTING ODOROUS MATTERS
First Claim
1. A cartridge-like chemical sensor, comprising:
- a housing that includes a base, a cover fixed to the base, an input opening, an output hole, and a channel for a gas to be analyzed, the channel extending between the input opening and the output hole;
a circuit board extending interiorly of the housing;
a integrated device fixed to the board and including a sensitive region open toward the channel and being of a material configured to bind with target chemicals in the gas to be analyzed; and
a driving motor for advancing the gas to be analyzed, the driving motor being housed in the housing.

Abstract
A cartridge-like chemical sensor is formed by a housing having a base and a cover fixed to the base and provided with an input opening, an output hole and a channel for a gas to be analyzed. The channel extends in the cover between the input opening and the output hole and faces a printed circuit board carrying an integrated circuit having a sensitive region open toward the channel and of a material capable to bind with target chemicals in the gas to be analyzed. A fan is arranged in the housing, downstream of the integrated device, for sucking the gas after being analyzed, and is part of a thermal control system for the integrated circuit.

15. A chemical sensor, comprising:
-
a housing that includes an input opening, an output hole, and a channel for a gas to be analyzed, the channel extending between the input opening and the output hole, the channel having a test portion laterally defined on opposite lateral sides by internal protruding structures extending interiorly from an inner surface of the housing that defines a first one of upper and lower sides of the channel; a circuit board positioned interiorly of the housing and in contact with the protruding structures, the circuit board having a surface defining a second one of the upper and lower sides of the test portion of the channel; a integrated device fixed to the board and including a sensitive region open in the test portion of the channel and of a material configured to bind with target chemicals in the gas to be analyzed; and a driving motor for advancing the gas to be analyzed, the driving motor being housed in the housing and positioned between the integrated device and the output opening. - View Dependent Claims (16, 17, 18, 19, 20)
