Description

Technical Field

[0001] The utility model relates to the technical field of incubators, in particular to a ventilation device for an incubator. Background Art

[0002] An incubator is a device for realizing artificial incubation of poultry eggs. According to its structure, it can be divided into a tunnel incubator and a box incubator. The box incubator mainly includes an incubation box and a turning device arranged therein. The main body of the turning device is an egg rack. The existing ventilation devices of incubators usually adopt axial flow fans to realize the internal ventilation of the incubator. However, since the axial flow fans are generally arranged on one side of the incubator and the air blows from one side to the other side, the air cannot evenly blow to each hatching egg, resulting in uneven heating of the hatching eggs. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a ventilation device for an incubator.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A ventilation device for an incubator includes an incubator. An axial flow fan is connected to the upper side of the incubator through a bracket. The air outlet of the axial flow fan is connected to two delivery pipes through a tee pipe. Each delivery pipe is connected to a ventilation pipe. The two ventilation pipes are both arranged in the incubator, and a group of ventilation holes are arranged on each ventilation pipe.

[0006] Preferably, a guide plate is connected in the tee pipe. The guide plate is a V-shaped plate, and its tip faces the axial flow fan.

[0007] Preferably, a spiral plate is connected in each ventilation pipe. The spiral plate forms a spiral cavity in the corresponding ventilation pipe, and the ventilation holes communicate with the spiral cavity.

[0008] The advantages of the utility model are as follows: The ventilation device for an incubator provided by the utility model extracts external air through an axial flow fan, then successively passes through the delivery pipes and the ventilation pipes, and finally is delivered into the incubator. The gas is discharged through the ventilation holes and can be evenly blown to the hatching eggs. The gas drives the hot air to blow to the hatching eggs, enabling the hatching eggs in the incubator to be evenly heated. Brief Description of the Drawings

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0013] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0014] As Figure 1 shown, a ventilation device for an incubator provided by the present invention includes an incubator 1, which is a conventional structure, provided with an exhaust fan and a heating mechanism, and the heating mechanism can heat the inside of the incubator 1.

[0015] An axial flow fan 3 is connected to the upper side of the incubator 1 through a bracket 2, and the air outlet of the axial flow fan 3 is connected to two conveying pipes 5 through a three-way pipe 4. As Figure 3 shown, a flow guide plate 4.1 is connected inside the three-way pipe 4. The flow guide plate 4.1 is a V-shaped plate, and its tip is oriented towards the axial flow fan 3. After the axial flow fan 3 extracts external air into the three-way pipe 4, through the diversion of the flow guide plate 4.1, the air flow is evenly guided into the two conveying pipes 5.

[0016] Each conveying pipe 5 is connected to a ventilation pipe 6, and the two ventilation pipes 6 are both arranged inside the incubator 1, and the two ventilation pipes 6 are respectively located on the front and rear sides inside the incubator 1. As Figure 2 shown, a spiral plate 6.1 is connected inside each ventilation pipe 6. The spiral plate 6.1 forms a spiral cavity 6.2 inside the corresponding ventilation pipe 6. The spiral cavity 6.2 can accelerate the flow of gas. A group of ventilation holes 7 are provided on each ventilation pipe 6. The group of ventilation holes 7 are evenly distributed on the ventilation pipe 6, and the ventilation holes 7 communicate with the spiral cavity 6.2. Through the ventilation holes 7, the gas can be evenly discharged.

[0017] This device extracts the outside air through the axial flow fan 3, then passes through the conveying pipe 5 and the ventilation pipe 6 in sequence, and finally conveys it into the incubator 1. The air is discharged through the ventilation holes 7 and can evenly blow towards the hatching eggs. The gas drives the hot air to blow towards the hatching eggs, enabling the hatching eggs in the incubator 1 to be evenly heated.
