Abstract
The utility model discloses a constant temperature hand-soaking bucket which is suitable for the medical staff to soak and disinfect the hand before operation. The constant temperature hand-soaking bucket is formed by the way that a heater and a temperature sensor are arranged on the bucket. The water temperature detected by the temperature sensor controls the switching or disconnecting of the heater by a temperature control circuit to keep a constant water temperature and make the water temperature always suitable for human body.
Description
This utility model relates to a kind of water temperature can constant bucket.
Existing hand sterilizing barrel is used to the disinfectant of packing into, and the sterilization of bubble hands is used before performing the operation for the medical worker.But when water temperature was low, as the pushing time is soaked in the bucket, user then can not feel well even endure cold.
The purpose of this utility model provides a kind of water temperature can constant hand sterilizing barrel, and it can make water temperature be suitable for human body all the time.
The purpose of this utility model is achieved in that installs a heater in bucket, and temperature sensor is fixed on the staving, and the water temperature signal that temperature sensor records turns on and off by the temperature control circuit control heater, fixes to keep water temperature.
Owing to adopt such scheme, with existing hand sterilizing barrel relatively, only increased by two parts of heater and temperature control, its structure is also fairly simple, uses very conveniently, has reached the purpose that makes water temperature be suitable for human body all the time.
Below in conjunction with drawings and Examples this utility model is elaborated.
Fig. 1 is the profile of a kind of concrete structure of this utility model.
Fig. 2 is the temperature control circuit basic circuit diagram.
In concrete structure shown in Figure 1, staving (1) is made by enamel or rustless steel, and tubular heater (2) is fixed in drum head, carries out the immersion heating at the bucket inner bottom part, utilizes the convection current of water to reach the purpose that whole inner bucket water solution is heated, its thermal efficiency height; Temperature sensor (3) is a kind of NTC type critesistor, and it is fixed in the drum head center position, and its resistance value changes with the inner bucket water temperature, and promptly high value is more little more for temperature, and temperature control circuit board (4) and supply socket (5) are installed on the extension under the drum head.
In electrical schematic diagram shown in Figure 2, temperature sensor (3) and resistance R
1The series connection dividing potential drop also will be divided in-phase input end that piezoelectric signal sends into operational amplifier A and the standard voltage value of inverting input compares, when water temperature is low, the resistance value of temperature sensor (3) is big, branch pressure voltage overgauge magnitude of voltage, operational amplifier A output high level makes the transistor T conducting, the relay J adhesive, its normally open contact JC connects, and makes heater (2) connect heating; When water temperature is elevated to when making branch pressure voltage be slightly less than standard voltage value, operational amplifier A is with output low level, and transistor T turn-offs, and relay contact JC disconnects, and heater (2) stops heating.Regulator potentiometer W is the adjustment criteria magnitude of voltage, and just can regulate needs constant water temperature value.
Claims (3)
1, a kind of hand sterilizing barrel that is made of staving (1), heater (2), temperature sensor (3), it is characterized in that: heater (2) and temperature sensor (3) all are installed on the staving (1).
2, hand sterilizing barrel according to claim 1 is characterized in that heater (2) is connected with the relay contact of temperature control circuit (4).
3, hand sterilizing barrel according to claim 1 is characterized in that temperature sensor (3) links to each other with temperature control circuit (4).
