One resistor voltage divider circuit 24 links to each other with described microcomputer circuit 23, in order to resistance change is converted to a magnitude of voltage;
One temperature perception circuit 25 links to each other with described resistor voltage divider circuit 24, is converted to resistance change in order to water temperature is changed.
Wherein, described temperature perception circuit 25 is placed in the below of described main body 10, with the convenient needs that measure water temperature.
In the metering circuit 20 described in a kind of electronic type measuring water temperature device that the utility model provides a vibration switch 21 is arranged in addition, link to each other with described microcomputer circuit 23, the cycle of rocking in order to foundation main body 10 continues to send signal to microcomputer circuit 23.
Comprise in the microcomputer circuit 23 described in the utility model: described analogy is to digital converting 230, in order to magnitude of voltage is converted to temperature value, described liquid crystal display control circuit 231, in order to show its temperature value, described storer 232 is in order to the letter value of depositing each circuit and measured temperature.
As shown in Figure 3, microcomputer circuit 23 provided by the utility model is the TMP47P420VN integrated circuit (IC) chip.
In the use, main body 10 can be put the what water surface (floating on the surface), and start main body 10 actions.The mode of startup main body 10 starts described in the utility model be have following several:
First kind, when main body 10 transfixions, these microcomputer circuit 23 place's what sleep states (being the OFF state), give microcomputer circuit 23 and can continue to send signal according to the cycle of rocking when vibration switch 21 finds that main body 10 has the situation of rocking, microcomputer circuit 23 then begins to enter duty (ON state) when having received signal; Otherwise, if microcomputer circuit 23 continue for some time (such as 3 minutes) do not receive always by vibration switch 21 during the signal of output, then enter sleep state (being the OFF state).
Second kind, can press any key (setting button 12 or start time control button 13) as temperature, can reach the effect that starts microcomputer circuit 23 equally.Yet, microcomputer circuit 23 is in working order the time, this temperature perception circuit 25 can be converted to the variation of water temperature changes in resistance (water temperature heal high resistance lower), again this changes in resistance is combined with resistor voltage divider circuit 24, to obtain a voltage, by voltage and the salty corresponding relation of temperature variation, the analogy that utilizes microcomputer circuit 23 is converted to temperature value to digital converting 230 with magnitude of voltage, the liquid crystal display control circuits 231 that see through again in the microcomputer circuit 23 are presented at LCD 11 with temperature value, for the user referring to.
What deserves to be mentioned is, the utlity model has the temperature set-up function, it can provide the function of user's set water temperature, set button 12 when pressing temperature, and continue to push a period of time (for example: 5 seconds) Hou, can carry out temperature sets, and temperature value that should setting is recorded in the storer 232, these 23 a period of times of microcomputer circuit can compare with the temperature value in the storer 232 measuring temperature value at present, and comparative result is presented at LCD 11 in the scale mode, if this moment is when finding that water temperature 9 exceeds temperature value in the storer 232, microcomputer circuit 23 can see through drive circuit of loudspeaker 22 and send a kind of caution sound music, and high temperature warning lamp 14 can glimmer too high with warning user temperature, otherwise, if find water temperature low the temperature value in the storer 232 when too many, then microcomputer circuit 23 can see through drive circuit of loudspeaker 22 equally and send another kind of caution sound music, and low temperature warning lamp 15 also can glimmer with the warning user.
In addition, the utility model also has a start time control function, (be with minute be unit), it is to push control 13 a period of times of button (for example: 5 seconds) start time, this microcomputer circuit 23 then enters the setting-up time pattern when receiving signal, and on LCD 11, (for example: 1) show numeral decided at the higher level but not officially announced, at this moment, click start time control button 13 again, this numeral decided at the higher level but not officially announced (for example: 2) can add 1, so repetitiousness is pushed start time control button 13 adjusting numeral decided at the higher level but not officially announced, when this numeral surpasses some numerals (for example: 30), then can be returned to 1; When configuring digital Hou decided at the higher level but not officially announced, microcomputer circuit 30 begins reciprocal, when the numeral inverse is extremely zero, then sees through drive circuit of loudspeaker 22 and sends musical sound, in order to remind bathtime to finish, 10 of this main bodys can enter sleep state (being the OFF state) in an appropriate time Hou (for example 60 seconds).
In sum, the utlity model has following effect: it can avoid user (especially child) not discover the too high or too low scald or uncomfortable that causes of water temperature because of careless mistake by set button 12 by temperature, and start time set button 13 is to like the bad habit of bathing at child, utilization can be set the start time effect of this creation, use and remind the adult, avoid child to waste the water source because of the overlong time of bathing.
