Abstract

A controllable door handle sanitizer includes a base and an outer housing coupled to the base and movable between an open and a closed position. The sanitizer also includes a holder that receives and holds a container that stores a germicide and includes a first valve member. The holder is coupled to the base such that when the outer housing is opened, the container can be inserted and removed. The holder includes a biasing mechanism for applying a biasing force against the container to maintain the container in a fully loaded position. The sanitizer also includes an electronic valve module that includes a housing that is coupled to the base by engaging locating and support members integrally formed as part of the base. The module is positioned relative to the holder such that in the fully loaded position, the first valve member is actuated and opened, whereby discharge of the germicide is determined by an operating state of a second valve member of the electronic valve module.

Claims

1. A controllable door handle sanitizer comprising:

a base and an outer housing coupled to the base and movable between an open and a closed position;

a holder that receives and holds a container that stores a germicide and includes a first valve member, the holder being coupled to the base such that when the outer housing is opened, the container can be inserted and removed; and

an electronic valve module that includes a housing that is coupled to the base by engaging locating and support members integrally formed as part of the base, the module being positioned relative to the holder such that when the container is in a fully loaded position with respect to the holder, the first valve member is actuated and opened, whereby discharge of the germicide from the sanitizer is determined by an operating state of a second valve member of the electronic valve module that is located downstream of the first valve member.

2. The controllable sanitizer of claim 1, wherein the holder comprises:

an inner sleeve member that receives a bottom of the container and includes an opening at a partially open bottom thereof to allow the first valve member to pass therethrough, the inner sleeve member having at least one locking tab, wherein the inserted container is securely held within the inner sleeve member; and

an outer sleeve member that receives the inner sleeve member into an interior thereof and includes an opening at a partially open bottom thereof to allow the first valve member to pass therethrough, the outer sleeve member having a complementary locking mechanism that selectively engages the locking tab resulting in the inner sleeve member being securely yet releasably engaged to the outer sleeve member and the first valve member extends below the outer sleeve member.

3. The controllable sanitizer of claim 2, wherein the inner sleeve member and outer sleeve member each comprises a hollow body and the locking mechanism comprises a locking rail that includes teeth that mate with the locking tab to interlockingly engage the inner sleeve member with the outer sleeve member.

4. The controllable sanitizer of claim 3, wherein the locking tab acts as a pawl and the outer sleeve member includes a receiving notch for initially receiving the locking tab before the locking tab interlockingly mates with the teeth by rotation of the inner sleeve member relative to the outer sleeve member, the receiving notch being disposed adjacent the locking rail.

5. The controllable sanitizer of claim 1, further including a controller that is operatively connected to a power source and to the electronic valve module for controlling the operation thereof, the controller having a housing that is coupled to the base and has an interior space that receives both the electronic valve module and at least the first valve member of the cartridge, wherein in the fully loaded position when the first valve member is permanently actuated, the first valve member is disposed within an inlet of the electronic control module.

6. The controllable sanitizer of claim 5, wherein the electronic valve module includes a flow director that has a hollow interior that receives the electronic valve module and includes an outlet that extends below the controller and is axially aligned with a bottom opening formed in the outer housing to permit the germicide to be discharged from the sanitizer in a generally downward direction toward the door handle.

7. The controllable sanitizer of claim 5, wherein the controller includes a printed circuit board and a sensing mechanism for sensing whether an object is in close proximity to an outlet through which the germicide is discharged, the sensing mechanism being in communication with the controller such that if the object is detected, the electronic valve module is prevented from operating.

8. The controllable sanitizer of claim 7, wherein the sensing mechanism includes a pair of sensors that are disposed at an angle relative to a vertical axis of the sanitizer, the sensors being located at or proximate a bottom of the outer housing such that a range of vision of the sensor extends downwardly from the sanitizer.

9. The controllable sanitizer of claim 7, wherein at least one sensor is disposed at a 45 degree angle relative to the vertical axis.

10. The controllable sanitizer of claim 1, wherein the second valve member comprises a solenoid valve that is located between an inlet of the electronic valve module that receives the first valve member and the germicide discharged therethrough and an outlet that is in communication with an outlet of the sanitizer through which the germicide is discharged.

11. A controllable door handle sanitizer comprising:

a base and an outer housing coupled to the base and movable between an open and a closed position;

a holder that receives and holds a container that stores a germicide, the container having a first valve member, the holder being coupled to the base such that when the outer housing is opened, the container can be inserted and removed;

an electronic valve module that includes a housing that is coupled to the base, the module being positioned relative to the holder such that when the container is in a fully loaded position with respect to the holder and the holder is disposed in a loaded position within the base, the first valve member is placed in fluid communication with the electronic valve module;

an inner sleeve member that receives a bottom of the container such that the container is securely held within the inner sleeve member and includes an opening at a partially open bottom thereof to allow the first valve member to pass therethrough;

an outer sleeve member that receives the inner sleeve member into an interior thereof and includes an opening at a partially open bottom thereof to allow the first valve member to pass therethrough, the outer sleeve member having a locking mechanism that selectively engages a portion of the inner sleeve member to provide a releasable engagement between the inner and outer sleeve members, thereby allowing removal of the cartridge from the housing, the outer sleeve member being coupled to the housing with the partially open bottom of the outer sleeve member being disposed proximate to electronic valve module; and

a controller including a power source for controlling operation of the sanitizer, the electronic valve module being operatively coupled to the controller such that the controller selectively signals the second valve member to open and close depending upon on user inputted operating selections that control when the germicide is discharged.

12. A controllable door handle sanitizer comprising:

a base and an outer housing coupled to the base and movable between an open and a closed position;

a holder that receives and holds a container that stores a germicide and includes a first valve member, the holder being coupled to the base such that when the outer housing is opened, the container can be inserted and removed;

an electronic valve module that includes a housing that is coupled to the base, the module being positioned relative to the holder such that when the container is in a fully loaded position with respect to the holder and the holder is disposed in a loaded position within the base, the first valve member is actuated and opened, whereby discharge of the germicide from the sanitizer is determined by an operating state of a second valve member of the electronic valve module that is located downstream of the first valve member and in fluid communication thereof; and

a controller including a power source for controlling operation of the sanitizer, the electronic valve module being operatively coupled to the controller such that the controller selectively signals the second valve member to open and close depending upon on user inputted operating selections that control when the germicide is discharged.
