Abstract

The utility model relates to a household constant temperature incubator, which is applicable to hatching various bird eggs, in particular applicable to hatching the eggs of rare birds, the number of which is relatively small. The utility model is characterized in that a case (4) is drawer-type structured, the bottom of the drawer (6) is a coarse iron sand net, an electric heat wire (8) is arranged under the net, a hot-water-bag warming space for temporary blackout is arranged on the undermost layer of the case (4), a monitoring mercury thermometer (1), an incandescent lamp (2) and an openable venthole (3) are arranged on the top of the case (4), a temperature sensor W is arranged in the case (4) and near the monitoring mercury thermometer (1). The utility model has simple structure, low cost, convenient usage, safety and reliability, even temperature, less energy consumption, overheat protection, and alarm and heat insulation circuits.

Description

Family expenses constant temperature incubator

Affiliated technical field

The utility model is applicable to the hatching of family to each stud bird ovum, especially is applicable to the hatching of the rare bird class ovum of negligible amounts.

Background technology

The volume of the incubator in the existing market is big, and the cost height is not suitable for promoting the use of to rural households, so that the peasant hatches the fowl ovum voluntarily, touches with hand on the hot warmer end of a kang, and temperature is not easy to grasp like this, and incubation rate is low, and take manually.Especially the hatching for the rare bird ovum may cause greater loss.

Summary of the invention

Big in order to solve existing incubator volume, the cost height is unsuitable for to problems such as family promote the use of, and the utility model provides a kind of family expenses constant temperature incubator, and this incubator is cheap, and easy to use the hatching for farmers' family opened up a path.

The technical scheme that its technical problem that solves the utility model adopts is: the incubator box body structure adopts drawer type, uses the crude iron gauze at the bottom of the drawer, and dress heating wire off the net, casing orlop leave temporary interruption with the hot-water bottle space of heating; But a ventilation hole that monitors with mercurial thermometer, an incandescent lamp and a folding is arranged at incubator box top, and temperature sensor W places in the incubator box near monitoring with near the mercurial thermometer; Said temperature control sensor W is that moulding above the thermo-responsive silk of refrigerator thermometer bored a hole on the shell, so that it is more responsive to temperature, bores two apertures of opening at a distance of certain distance on refrigerator thermometer plastic housing edge, so that use during design temperature; On the refrigerator thermometer plastic housing, install two contacts additional, use the contact with thermosensitive wire pointer formation constant temperature and overtemperature protection.

The beneficial effects of the utility model are: it has simple in structure, and is cheap, easy to use, safe and reliable, and the temperature field is even, and temperature range is little, the outstanding advantage of the little grade of energy consumption, and be provided with overtemperature protection and warning and thermal circuit.

In Fig. 1, Fig. 2,1 mercurial thermometer, 2 incandescent lamps, 3 ventilation holes, 4 casings, 5,6 drawers, 7 handles, 8 heating wire, 9 drawer sides, 10 cushion blocks, 11 break contacts, 12 thermosensitive wires, 13 thermometer housings, 14 design temperature holes, 15 closing contacts.

Embodiment

Incubator box casing 4 structures adopt drawer type, 6 ends of drawer crude iron gauze, dress heating wire 8 off the net, casing 4 orlops to leave to deal with temporary interruption with the hot-water bottle space of heating.But Φ 20 ventilation holes 3 of a folding are established on incubator box top, so that supply the usefulness of ovum breathing in the hatching process.Temperature sensor W places in the incubator box near monitoring with near the mercurial thermometer 1, adopt refrigerator thermometer to be temperature control sensor W, on the plastic housing above temperature control sensor W thermosensitive wire 12 pointers, bore the hole of a Φ 10, make it more responsive to temperature, on the plastic housing edge, bore two apertures 14 at a distance of the Φ 3 of 1.5cm, so that use during design temperature, on plastic housing, install two contacts 11,15 additional, use the contact with thermosensitive wire 12 pointers formation constant temperature and overtemperature protection; In circuit, temperature controller contact P1 is connected with contact 11, and temperature controller contact P2 is connected with contact 15, and thermosensitive wire 12 pointers connect DC voltage.

Its operation principle is: after power switch K connects, exchange 6V voltage through rectifying tube Z ₁-Z ₄Be rectified into DC voltage, through contactor J ₁Magnetizing coil add to triode θ colelctor electrode, simultaneously by temperature controller contact P1 and resistance R ₁Trigger triode Q saturation conduction makes relay J ₁Adhesive, contact JK-1 connects.Alternating current 220V voltage is through JK ₁And normally-closed contact JK-2 is added to heating wire R ₄, incubator box is heated up, behind the arrival preset temperature, the P1 automatic disconnection of temperature controller contact, relay J ₁Outage, JK-1 disconnects, and stops to heat.At this moment contact JK-1 gets back to the insulation position, slowly heats by thermal circuit.Adjust R ₅, can adjust heat insulation effect.

If short trouble appears in circuit, burner on light is that green luminotron will not work.

If short trouble appears in circuit, temperature controller contact P2 will connect, and make relay J ₂Work, normally-closed contact JK-2 disconnects, and makes R ₄Outage.And crossing thermal light is that red luminotron ignites, and does the indication of reporting to the police.

The utility model adopts safe voltage, thermal circuit is arranged, overheat protective function is arranged.Because it is reasonable in design that component is selected, the possibility that breaks down drops to minimum.

Claims

1. family expenses constant temperature incubator, comprise door (5), handle (7), drawer side (9), cushion block (10), temperature sensor W housing (13), design temperature hole (14) is formed, it is characterized in that: casing (4) structure adopts drawer type, drawer (6) end is with the husky net of crude iron, and dress heating wire off the net (8), casing (4) orlop leave temporary interruption with the hot-water bottle space of heating, casing (4) top has one to monitor with mercurial thermometer (1), an incandescent lamp (2) but and the ventilation hole of a folding (3), temperature sensor W places in the casing (4) near monitoring with near the mercurial thermometer (1).
