Description

Egg hatching device

The present invention relates to an incubator, and more particularly to an egg incubator that can control internal environmental parameters.

The hatching rate of eggs is greatly affected by the ambient temperature. Therefore, controlling the temperature in the incubator to the optimal incubation conditions is an important task for egg hatching.

Among them, in order to make the temperature in the incubator uniform, TW M370934 (hereinafter referred to as '934 case) discloses an improved structure of the hatching box, which is divided into an hatching area and an electric heating area by a plurality of spacing elements in the hollow body, and The two regions are respectively disposed at the lower two ends of the spacer element, and a lower air guiding homogenizing orifice plate and a lower air guiding homogenizing orifice plate are arranged to equalize the hot air through the hatching area to make the temperature of the hatching area More uniform.

However, in the case where the temperature of the incubator is too high, the '934 case does not provide an active cooling mechanism. The cooling depends mainly on the way the egg farmers manually open the sides of the hatch box and the upper mouth to make the hatchery box The gas exchanges with the outside cold air to reduce the temperature inside the incubator, thereby maintaining the hatching efficiency of the egg. However, this method can not only maintain stable and favorable egg hatching environment conditions, but also has a more effective effect in the summer when the environment is extremely hot. Not at all.

In order to enable the incubator to actively cool down, TW 275943 (hereafter referred to as '943 case) provides an incubator temperature/humidity/recooling controller that detects the inside of the incubator by the temperature/humidity sensing unit. Temperature/humidity to decide whether to turn on the heating/humidifier for heating/humidifying operation; in the cooling part, the '943 case uses the regenerative timer to turn on the cooler after a fixed time interval; thus, it is known that '943 Addition of the case The heat exchanger and the cooler are independently operated, so it is very likely that while the heater is operating, the cooling timer turns on the cooler at a predetermined time to form a heater and a cooler simultaneously, which is invisible. The waste of energy is also unable to achieve the expected heating/cooling effect.

In addition, since the eggs will undergo respiration during the hatching process (especially in the late incubation period), CO ₂ will be produced, and if the concentration of CO _{2 in the} tank is too high, it will easily affect the hatching rate or make the newly hatched Chicken suffocation died, but neither the '934 case nor the '943 case provided a control mechanism for the concentration of CO _{2 in the} incubator. This is another concern that affects the efficiency of hatching of the hatch box.

The main object of the present invention is to provide an egg incubator capable of controlling the CO ₂ concentration in the incubation chamber to an appropriate range.

Thereby, the CO ₂ concentration of the hatchery can be controlled within a predetermined range, and it is possible to avoid affecting the hatching rate or suffocating the newly hatched young chicken.
