Abstract
An atomizer for dispensing a powder or liquid product which is atomized by a stream of compressed air and further has either (1) means to prevent or stop the product from atomizing in response to a positive pressure in the atomizer or (2) a secondary reservoir located between the product reservoir and a product outlet from which the product is atomized, said secondary reservoir is in fluid connection with a second chamber, the second chamber being operable in response to a positive pressure in the atomizer to drive fluid from the secondary reservoir.
Claims17
An atomizer comprising:
- an atomizer jet having a product outlet from which a powdered or liquid product can be atomized;
- means for sourcing compressed air;
- a duct for leading the said sourced compressed air to the atomizer jet;
- a product reservoir;
- means for supplying the product from the reservoir to the product outlet for atomization;
- a first chamber into which atomized product can diffuse;
- and
- means to prevent or stop the product from being atomized, the means to prevent or stop atomization being located between the reservoir and the product outlet and configured to stop the passage of the product to the product outlet in response to a positive pressure in the atomizer.
An atomizer comprising:
- an atomizer jet having a product outlet from which product can be atomized;
- means for sourcing compressed air;
- a duct for leading the said sourced compressed air to the atomizer jet;
- a product reservoir;
- means for supplying the product from the reservoir to the product outlet for atomization;
- a first chamber into which atomized product can diffuse;
- means to prevent or stop the product from being atomized, the means to prevent or stop atomization being located between the reservoir and the product outlet, and including:
- a second chamber having an exit;
- a secondary reservoir through which the product passes before reaching the product outlet and which is in fluid connection with the exit of the second chamber, the second chamber being operable in response to a positive pressure in the atomizer to drive fluid from the secondary reservoir;
- and
- a one-way valve which moves in to an open position when the pressure within the atomizer is positive, and causes the means to prevent or stop atomization to stop the passage of the product to the product outlet.
An atomizer comprising:
- an atomizer jet having a product outlet from which product can be atomized;
- means for sourcing compressed air;
- a duct for leading the said sourced compressed air to the atomizer jet;
- a product reservoir;
- means for supplying the product from the reservoir to the product outlet from atomization;
- a first chamber into which atomized product can diffuse;
- and
- means to prevent or stop the product from being atomized, the means to prevent or stop atomization being located between the reservoir and the product outlet, and including:
- a second chamber having an exit;
- a rigid sidewall separating the first and second chamber;
- a secondary reservoir through which the product passes before reaching the product outlet and which is in fluid connection with the exit of the second chamber, the second chamber being operable in response to a positive pressure in the atomizer to drive fluid from the secondary reservoir, and
- wherein the second chamber includes an opening, and in that the atomizer further comprises a one-way valve which closes the opening in the second chamber;
- and
- wherein the secondary reservoir includes a first entrance leading to the second chamber and a second entrance leading into the secondary reservoir from the reservoir;
- and in that the first entrance is larger than the second entrance.
