Abstract
The utility model relates to a low voltage constant temperature electric heater, comprising an outer housing and an electric heating elements assembly arranged in the outer housing, wherein, the electric heating elements assembly comprising an insulating box, and the inner of the box is provided with electric heating elements, and electrodes arranged on the electric heating elements. The electric heating elements are positive temperature coefficient thermistors (PTC) whose resistances are 10-100 ohm at ordinary temperature and working voltages are 6-36 volts. The utility model uses both alternating-current and direct-current, and the working power supply can be an accumulator, a battery and the power source of the power supply system of cars and ships, and the utility model is in particular suitable for the army doing field operation, scientific research workers and staff.
Description
The utility model belongs to the low pressure constant temperature electric heater.
Existing various electric heater, (electric heating dish, mosquito repellant, hand warmer etc.), its operating voltage is 220 volts, must could work by mains supply, therefore, can not use because of no electric network source the personnel of outlying mountain area, the water surface and field work.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of low pressure constant temperature electric heater of AC/DC is provided, with the people that the satisfy no electric network source place demand to household electrical appliance.
The low pressure constant temperature electric heater of realizing the utility model purpose is made of the heating assembly of installing in shell and the shell, the heating assembly comprises the electrothermal device of installing in the insulation booth, box and is arranged on pair of electrodes on the electrothermal device, electrothermal device is the normal temperature resistance at 10～100 ohm semistor (PTC), and its operating voltage is 6～36 volts.
The utility model is because the normal temperature resistance of electrothermal device is little, and operating voltage is low, so battery, storage battery and car, ship electric power system power supply all can make its power supply, and the army, the scientific research personnel that are specially adapted to field work use.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of structure chart of the low pressure constant temperature electric heater that proposes according to the utility model.
Fig. 2 is the circuit diagram of Fig. 1.
Embodiment:
Low pressure constant temperature electric heater in the present embodiment is used for mosquito repellent, its structure as shown in Figure 1 and Figure 2, the heating assembly of installing in the shell (6) comprises insulation booth (2), electrothermal device (1), electrode (3) and heating board (5), insulation booth is made up of box body and lid (4), the box body ceramic making, lid is made of mica sheet; Electrothermal device (1) is that the normal temperature resistance exists: 10～100 ohm, operating voltage are positioned at insulation booth (2) at 6～36 volts semistor (PTC); Electrode (3) is made with copper or stainless sheet steel, for a pair of, is separately positioned on the upper and lower of electrothermal device (1), and is connected with lead (7); Heating board (5) connects firmly with lid (4), insulation booth (2), is used to place the mosquito repellent tablet.
Structure of the present utility model is not limited to the foregoing description, and its protection domain is determined by claims.
The utility model can be widely used in the various household electrical appliance that need to keep constant temperature, and when designed enclosures, selecting for use according to the purposes of heater of its structure and material decided.
