Abstract
The utility model relates to a safe device for health-care instrument, which is composed of a heating element (2), a timer (3), a shell, etc., wherein, a reducing transformator (1) of a power supply is arranged in the shell, the power supply is connected with the heating element by the reducing transformor (1), and a resettable fuse (4) is connected in series to the heating element. The low-voltage working of the utility model can ensure that users' electric apparatuses are safe. The resettable fuse can also reliably prevent a risk which is caused by overheating. The utility model has the advantages of small size, simple structure and reliable operation.
Description
The utility model relates to a kind of safety device of the instrument that keeps healthy, especially the safety device of family expenses thermotherapy type health care instrument.
Existing health care instrument, especially family expenses thermotherapy type health-care appliance device are widely used, but its voltage is set in line voltage, even timer control is arranged, still have risk of overheating.
The purpose of this utility model is: a kind of thermotherapy type health care instrument, especially family expenses thermotherapy type health care instrument safety device are provided, can reliably prevent danger overheated and that cause than high working voltage.
The purpose of this utility model is achieved in that a kind of safety device of the instrument that keeps healthy, comprise heater element and formations such as timer, shell, it is characterized in that being provided with in the shell power step-down transformer, power supply connects heater element again by a step-down transformer, and the self-healing fuse of connecting on heater element.
Further improvement of the utility model is: described power step-down transformer is the transformer of two groups of above voltage outputs.
Characteristics of the present utility model are: low voltage operating can guarantee user's security appliance, to the danger of human body without any injury, adapts to the lower temperature heating of long period, and the efficacy of a drug of the medicine bag of being more convenient for is overflowed.Self-healing fuse can also reliably prevent the overheated danger that causes.The utility model volume is little, and is simple in structure, reliable operation.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model structural representation
As shown in the figure, the utility model comprises that heater element 2 and timer 3 constitute, connect heater element from the power supply input again by a step-down transformer 1, heater element can be the electrothermal therapy band, the electrothermal therapy band is to add the Chinese medicine cartridge bag, can produce electromagnetism medicine and far complex treatment, be the instrument as articular system diseases such as Taiyi therapeutic equipment treatment cervical vertebra, osteoproliferation, arthritis.When the power of heater element during generally at 15-60w, the power of transformer designs like this.In addition, series connection self-healing fuse 4 for example can adopt commercially available RXE065 type on the heating operation element.Self-healing fuse 4 disconnects when overheated, connects when temperature descends, guarantee can not burnt by high temperature with the person, and be the circuit breaker of a kind of similar PTC (positive temperature coefficient resistor).Power step-down transformer is output as safe voltage, and generally below 36 volts, its output has two to three groups, as 22,27,36 volts, is provided with tap changer 5.6 is relay indicating light.Can conveniently adjust power output like this, add the cooperation of timer, right to use security of users is better.
Claims (2)
1. the safety device of the instrument that keeps healthy, comprise heater element (2) and formations such as timer (3), shell, it is characterized in that being provided with in the shell power step-down transformer (1), power supply connects heater element again by a step-down transformer, and the self-healing fuse (4) of connecting on heater element.
2. by the safety device of the described health care instrument of claim 1, it is characterized in that described power step-down transformer is the transformer (1) of two groups of above voltage outputs.
