Description
BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a temperature monitoring device, and more particularly to a temperature monitoring device for a shower system including an improved and simplified structure or configuration for monitoring and displaying the water temperature of two or more showering facilities.

2. Description of the Prior Art

Various kinds of typical shower systems or apparatuses have been developed and provided for showering purposes, and various kinds of typical temperature monitoring devices have been developed and attached to the typical shower systems or apparatuses and provided for monitoring and displaying the water temperature flowing out of the typical shower systems or apparatuses and for allowing the user to shower with the appropriate water temperature, and for preventing the user from being hurt by the over-heated water and the like.

For example, U.S. Pat. No. 4,030,360 to Fortune, U.S. Pat. No. 4,161,881 to Raz, U.S. Pat. No. 4,281,543 to Raz, U.S. Pat. No. 4,509,550 to Monk, U.S. Pat. No. 4,743,120 to Bowen, U.S. Pat. No. 5,172,860 to Yuch, U.S. Pat. No. 7,124,452 to Banza, U.S. Pat. No. 7,174,579 to Banza, and U.S. Pat. No. 7,252,431 to Caramanna disclose several of the typical temperature monitoring devices attached to various kinds of typical shower systems or apparatuses for monitoring and displaying the water temperature flowing out of the typical shower systems or apparatuses, and normally comprise a temperature sensor or detector attached to the shower head or nozzle of the shower systems or apparatuses for sensing or detecting the water temperature flowing out of the shower head or nozzle.

However, the typical temperature monitoring devices may only be provided and attached to the shower head or nozzle, but may not be provided and attached to the other showering facilities; i.e., the typical temperature monitoring devices may not be used for monitoring and displaying the water temperature flowing out of two different showering facilities, such as the shower head and the spraying nozzle.

For example, U.S. Pat. No. 5,749,552 to Fan, U.S. Pat. No. 7,043,776 to Wu, and U.S. Pat.
