Description

A kind of safety heat-preserving foot bath
Technical field
The utility model belongs to household apparatus, is related specifically to a kind of insulation foot bath.
Background technology
Traditional foot bath is not with heating and heat preserving function, and lavipeditum a period of time will toward heating water in foot bath, and to keep suitable temperature to steep pin, it is very inconvenient to use.
Summary of the invention
In order to solve described traditional foot bath Problems existing above, the utility model provides a kind of safety heat-preserving foot bath, has effect of insulation, energy-conservation, safety.
The utility model solves the technical scheme that its technical problem adopts:
A kind of safety heat-preserving foot bath, comprises basin body, water level switch, temperature control circuit, heating wire, press button, battery case, USB interface.Described temperature control circuit, comprises temperature sensor; Described basin body, is provided with elastic bottom plate bottom it, and the below of elastic bottom plate is provided with heating wire and press button; Water level switch and temperature sensor is provided with in the side of basin body.Also be provided with battery case and USB interface in the below of elastic bottom plate, described temperature control circuit adopts powered battery or external power supply to be powered by USB interface.
Whether press button recited above, water level switch, temperature sensor jointly participate in controlling heating wire and heat.When have pin stretch into basin body apply pressure to elastic bottom plate and in foot bath, have enough water to make water level switch be in the state of conducting time, power supply is just powered to temperature control circuit, and whether heating wire generates heat, and also depends on the water temperature in foot bath.Therefore, design of the present utility model fully reaches energy-conservation effect, meanwhile, because adopting powered battery or USB interface to power, uses very safe.
The beneficial effects of the utility model are mainly manifested in: have insulation, energy-conservation, safe effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of a kind of embodiment water level switch of the utility model.
Fig. 3 is the circuit diagram of a kind of embodiment of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is further described.
As shown in Figure 1, a kind of safety heat-preserving foot bath, comprises basin body 1, water level switch K1, temperature control circuit, heating wire 2, button switch K 2, battery case 3, USB interface 4.Described temperature control circuit, comprises temperature sensor 5; Described basin body 1, is provided with elastic bottom plate 6 bottom it, the below of elastic bottom plate 6 is provided with heating wire 2 and button switch K 2; Described elastic bottom plate 6 adopts transcalent metal to be material, and described heating wire is attached to the below of elastic bottom plate 6.Water level switch K1 and temperature sensor 5 is provided with in the side of basin body 1.Be provided with dividing plate 7 in the below of elastic bottom plate 6, the below of dividing plate is provided with battery case 3 and USB interface 4, and button switch K 2 is arranged on the top of dividing plate.Described temperature control circuit can adopt 3 joint 1.5V powered battery, or uses the equipment such as charger baby to be powered by USB interface.
Described transversal switch K1, as shown in Figure 2, comprises switch contact, ball float 11; Described switch contact comprises contact 12a and lower contact 12b, and described lower contact 12b has elasticity.When there being enough water in foot bath, water enters from water inlet 13, and ball float 11 floats, and is upwards pushed up by lower contact 12b, and two contacts are communicated with.
Further, described temperature control circuit, also comprises variable resistor R1, for regulating water temperature, namely jointly determines will heat under what kind of water temperature with temperature sensor 5.
Further, in order to ensure the normal work of temperature control circuit, described temperature sensor 5 is positioned at the below of water level switch K1.
Embodiment recited above, its operation principle as shown in Figure 3.When water level in foot bath is enough high, water level switch K1 conducting; When there being pin to step down in foot bath, button switch K 2 conducting.Now, if water temperature is higher, then temperature sensor 5 resistance is lower, NAND gate output low level, transistor T1 not conducting; If water temperature is lower, then temperature sensor 5 resistance is higher, and NAND gate exports high level, and transistor T1 conducting, heating wire 2 generates heat.Regulate variable resistor R1, the threshold value that heating wire 2 heats can be changed.
Above-described is only a kind of embodiment of the present utility model, and to one skilled in the art, under the prerequisite not departing from the utility model principle, some changes made, all should be considered as belonging to protection domain of the present utility model.
