DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0021] like Figures 1 to 6 As shown in the figure, a heating device for an infant incubator comprises a base 1, an electric control box 2 is installed inside the bottom end of the base 1, a culture bin card slot 3 for connecting the culture bin is opened on the surface of the base 1, an air inlet channel 4 is installed on the upper part and left and right sides of the base 1, and an air outlet channel 5 is installed on the lower part and front and back sides of the base 1. The air inlet channel 4 and the air outlet channel 5 inside the base 1 are connected through a connecting hole, and a heating air supply frame 7 is installed inside the connecting hole, thereby allowing the airflow to flow along the direction of the air inlet channel 4, the connecting hole and the air outlet channel 5, and be heated after passing through the heating air supply frame 7. A filtering structure 6 is installed inside the air inlet channel 4, thereby preventing external debris from entering the position of the heating air supply frame 7, and a temperature control structure 8 is installed inside the air outlet channel 5, thereby effectively preventing the high-temperature airflow from flowing out from the position of the air outlet channel 5.

[0022] The filtering structure 6 includes a filter screen 10. An installation groove 9 for installing the filter screen 10 is opened at a position inside the base 1 corresponding to the air inlet channel 4. The internal thread of the installation groove 9 is connected with a sealing top tightening cap 11 for tightening the filter screen 10. Therefore, when the user needs to replace the filter screen 10, the filter screen 10 can be taken out by removing the sealing top tightening cap 11, which is very convenient for replacement operation.

[0023] The heating and air supply frame 7 includes a fan 15. A through hole 12 is opened at the bottom end of the base 1 at the position corresponding to the connecting hole. The internal thread of the through hole 12 is connected to a sealing plate 13. A support plate 14 is installed on the surface of the sealing plate 13. The top end of the support plate 14 is arranged inside the connecting hole and supports the bottom end of the fan 15. Insulating pillars 16 are distributed on the top side of the fan 15. The top end of the insulating pillars 16 is installed with an electric heating pipe 17, so that the fan 15 can provide the power required for the airflow to flow, and the electric heating pipe 17 can heat the airflow passing through.

[0024] The temperature control structure 8 includes a partition 18, which is distributed inside the air outlet channel 5, and the partition 18 guides the airflow inside the air outlet channel 5 into an S-shaped flow. A temperature sensor 19 is installed inside the air outlet channel 5 on one side of the connecting hole corresponding to the partition 18, and a temperature sensor 2 20 is installed inside the air outlet channel 5 on the other side of the partition 18. Support plugs 22 are installed at the bottom ends of the temperature sensor 19 and the temperature sensor 2 20, and a mounting hole 21 is opened inside the base 1 corresponding to the support plug 22, thereby enabling the temperature of the airflow flowing through to be measured by the temperature sensor 19 and the temperature sensor 2 20, thereby facilitating the user to measure the temperature of the airflow discharged from the air outlet channel 5.

[0025] A cooling channel 23 is provided on the side of the connection hole between the fan 15 and the electric heating tube 17, an air inlet 24 is provided at the bottom of the air outlet channel 5 between the temperature sensor 19 and the partition 18, the cooling channel 23 and the air inlet 24 are connected through a slide groove 26, a sealing plate 27 is slidably installed inside the slide groove 26, a fixing plate 29 is installed at the position of the slide groove 26 on the side of the base 1, and the fixing plate 29 is connected to the sealing plate 27 through an electric push rod 28. When the temperature measured by the temperature sensor 19 is higher than the set temperature, the electric push rod 28 is shortened through the electric control box, thereby causing the sealing plate 27 to move backward, so that the cooling channel 23, the slide groove 26 and the air inlet 24 are connected. At this time, the fan 15 and the air guide plate 25, the unheated airflow enters the position between the temperature sensor 19 and the partition 18 along the cooling channel 23, the slide groove 26 and the air inlet 24, thereby mixing the low-temperature airflow with the high-temperature airflow, thereby cooling the high-temperature airflow, and then detecting and measuring it through the temperature sensor 20. When the temperature is still too high, the electric control box 2 stops the heating operation of the electric heating tube 17. When the airflow temperature measured by the temperature sensor 19 again is within the set temperature range, the electric control box 2 works to reset the electric push rod 28, thereby isolating the cooling channel 23 and the air inlet 24 through the sealing plate 27, thereby preventing the unheated airflow from entering the interior of the air outlet channel 5.

[0026] An air guide plate 25 is installed inside the connection hole at a position above the cooling channel 23 , so that when the air flow inside the air outlet channel 5 is cooled, the unheated air flow between the electric heating tube 17 and the fan 15 enters the cooling channel 23 .

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
