Abstract
The device belongs to the water temperature heating device of the fishbowl for the indoor fish culture, in particular to a PTC electro-thermal insulating device for the fishbowl, which is composed of a sealing tube and an inner heating element. The sealing tube adopts a glass tube or a stainless steel tube; the inner heating element adopts the PTC element; the both ends are provided with bakelite plates; the two surfaces are bonded with conducting polar plates which are arranged into the glass tube; the inner part of the glass tube is filled with the quartz sand, and finally, the glass tube is sealed with a rubber plug. The conducting polar plates are welded with power supply lines which are extracted from the middle of the rubber plug, and the power supply lines can be directly connected to the power supply. The PTC electro-thermal insulating device for the fishbowl has the advantages that the PTC element is adopted as a heating body; the naked fire can not be generated, and the PTC electro-thermal insulating device for the fishbowl has better temperature regulating performance, simple structure, low cost, and convenient usage.
Description
The utility model belongs to aquaricullure fish jar water temperature heater.
Present aquaricullure; particularly support tropical fish; require water temperature between 20 ℃～24 ℃, because boreal climate is cold, indoor temperature is low; water temperature is difficult to reach above-mentioned requirements; the method that general feedwater is heated is put into subsidy measures such as water or frequent heat exchange water with a bulb, for above method, and electricity wasting; and can not automatic temperature-control, so survival rate is quite low.
Be the unmanageable problem of water temperature of breeding fish more than solving, it is the fish jar PTC electric warmer that thermal source is made with the PTC element that the purpose of this utility model provides a kind of, the insulation heating element heater is placed in the airtight glass tube, the feedwater of energising back is heated and is remained under the steady temperature, has effectively solved the problem of water temperature automatic constant in the fish jar.
Structural design of the present utility model is achieved in that fish jar PTC electric warmer is made up of sealed tube and heating element heater two parts, the outside is the glass tube (or stainless steel tube) of an end opening, the inside is a heating element heater, its detailed structure is the bakelite plate of putting at PTC element two ends with the wide uniform thickness of PTC element, PTC element and two ends bakelite plate are put in one plane, the two sides connects with sticking with glue in the middle of the conductive plate then, make the PTC element, the conductive plate on bakelite plate and two sides is bonded as one, two conductive plates source of welding current line are respectively drawn, above-mentioned parts are put into glass tube together, quartz sand is filled up in the centre, seal with rubber stopper at last, power line is drawn in the middle of rubber stopper.Need only during use warmer is put into fish jar, the logical power supply of going up gets final product, hold linearity curve according to the resistance-Wen of PTC element and know that when reaching Curie-point temperature, its resistance is undergone mutation, resistivity sharply rises, electric current descends, and has very big positive temperature coefficient, thereby power is descended rapidly, there is a steady temperature scope on the holding element surface, promptly is that the PTC heating has temp autocontrolled function.According to the different requirements of water temperature, can design the element of different curie points.
The advantage of the utility model: the flames of anger of PTC element heating body, element itself has adjustment performance preferably, need not be equipped with temperature regulating device, good insulation preformance, power saving, simple in structure, cost is low, easy to use.
Detailed structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a fish jar PTC electric warmer structure principle chart.Its structure is by known to Fig. 1, and (1) is sealed tube, is made by glass tube or stainless steel tube, and the inside is a heating element heater; (2) be the PTC element, its both sides are bakelite (6), the same with the PTC component size, the two sides is stained with electric conduction electrode-plate (3), makes whole becoming one, and puts into glass tube (1), two are filled up quartz sand (7), termination at its glass tube (1) is sealed by rubber stopper (4), and power line (5) is drawn in blocking, can be directly connected on the mains supply.
Claims (2)
1, a kind of fish jar PTC electric warmer, it is characterized in that forming by sealed tube (1) and inner heating element heater (2), outside sealed tube (1) is the glass tube or the stainless steel tube of an end opening, the inside heating element heater is PTC element (2), the bakelite plate (6) with the wide uniform thickness of PTC element is put at two ends, upper and lower surface is bonding with conductive plate (3), fills up with quartz sand (7) in glass tube (1), uses rubber stopper (4) to seal at last.
2, by the described fish jar PTC electric warmer of claim 1, it is characterized in that on two conductive plates (3), being welded with respectively power line (5), in the middle of rubber stopper (4), draw.
