[0002] The electric constant temperature incubator is a kind of experimental equipment widely used in the fields of biology, medicine, agriculture, environmental science, etc. It provides a stable culture environment for experimental samples through precise temperature control. In the field of biotechnology, it can be used for the cultivation of microorganisms, the incubation of cells and the conduction of biological reactions. In medical research, it supports stability testing and the preservation of biological products, etc.

[0003] To achieve the above functions, electric constant temperature incubators usually have electric heating elements to provide precise temperature control to create the temperature in the incubator chamber as required. Temperature uniformity is crucial to ensure that all samples in the incubator can grow under the same conditions. In the same incubator chamber, uneven temperature distribution increases the difference in experimental results and affects data accuracy.

[0004] For most electric constant temperature incubators, the heating method is relatively simple, usually using electric heating wires, which are arranged in an equipment compartment on one side of the electric constant temperature incubator. Therefore, the temperature of the part of the culture room close to the electric heating wire is usually higher, and the temperature of the part far from the electric heating wire is lower. Summary of the invention

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses an electric heating constant temperature incubator with uniform temperature. Figure 1 An electric constant temperature incubator with uniform temperature includes a box body 1, a culture chamber 2 is provided inside the box body 1, and a door 13 is provided accordingly. A plurality of heat insulation boards 22 are horizontally arranged inside the box body 1, and the plurality of heat insulation boards 22 divide the culture chamber 2 into a plurality of heat chambers 21, and a culture box 23 is formed in each heat chamber 21. The side walls of the culture chamber 2 and the culture box 23 are made of heat-insulating materials, such as calcium carbonate board, glass fiber, etc. The experimenter opens the door 13 and places a culture dish in each culture box 23.

[0023] Reference Figure 1 A device bin 11 is provided on one side of the box 1, and a heating wire and a blower are fixedly connected in the device bin 11. The device bin 11 is connected to the culture chamber 2. To be precise, the device bin 11 is connected to each heat chamber 21, that is, an air inlet 12 connected to the device bin 11 is provided on a side wall of each heat chamber 21 close to the device bin 11. Thus, the heating wire generates heat to heat the air in the device bin 11, and the blower delivers the hot air in the device bin 11 into each heat chamber 21 from the air inlet 12.

[0024] Reference Figure 1 The bottom side of the incubator 23 is formed on the insulation board 22, a gap is formed between the top side of the incubator 23 and the insulation board 22 above, and a gap is formed between the side of the incubator 23 and the inner wall of the heat chamber 21. However, a channel for hot air to pass through is opened on the side wall on the same side of the insulation board 22 and the incubator 23. The above-mentioned channel and gap together constitute an air intake channel, and the hot air entering from the air inlet 12 flows into the air intake channel.

[0025] Reference Figure 1 , a plurality of distribution pipes 24 are extended from the inner wall of one side of the incubator 23 away from the air inlet 12 toward the inside of the incubator 23, and the plurality of distribution pipes 24 are horizontally arranged and evenly distributed at the four corners of the side of the incubator 23, and the inside of the distribution pipe 24 is hollowed out into a shell shape, and an air inlet 242 connected to the air inlet channel is provided on the side wall of the incubator 23 away from the air inlet 12 corresponding to the distribution pipe 24; a plurality of through holes 241 are provided on one side of the distribution pipe 24, and for the distribution pipe 24 distributed at the top of the incubator 23, the through hole 241 is provided on the bottom side, and for the distribution pipe 24 distributed at the bottom of the incubator 23, the through hole 241 is provided on the top side, and the through holes 241 are evenly spaced along the length direction of the distribution pipe 24; thereby, the hot air flowing into the air inlet channel flows into the incubator 23 through the hot air entering the distribution pipe 24, and the hot air is evenly distributed through the through hole 241.

[0026] Reference Figure 1 , the incubator 23 also needs to be provided with an air outlet 25 for hot air to flow out. The air outlet 25 is provided at the bottom of a side wall of the incubator 23 away from the door 13. The side wall of the incubator 23 corresponding to the air outlet 25 is provided with an air outlet channel 251 connected to the outside. The air outlet channel 251 runs through the internal space of the air inlet channel, so that the hot air discharged from the air outlet 25 is isolated from the internal space of the air inlet channel and smoothly discharged to the outside. It should be noted that in this embodiment, the air outlet channel 251 is set at the edge of one side of the side wall of the incubator 23 close to the air inlet 12, so that the hot air entering the incubator 23 flows from the perforation 241 on the distribution pipe 24 to the side of the incubator 23 close to the air inlet 12, and then discharged from the air outlet 25, thereby improving the heating effect of the heating box.

[0027] Reference Figure 1 , each incubator 23 is provided with an opening on one side close to the door 13, and the edge of the incubator 23 on the side close to the door 13 is flush with the edge of the insulation board 22, so that when the door 13 is closed, the door 13 closes the incubator 23, and closes each heat chamber 21 through the insulation board 22. The part of the door 13 corresponding to each incubator 23 is fixedly connected with a horizontally arranged mesh plate 14, and a vertical side of the door 13 is hinged to a vertical side edge of the box body 1, so that when the door 13 is opened, the mesh plate 14 rotates in the horizontal plane with the door 13 to move out of the incubator 23, and at the same time drives the culture dish placed on the mesh plate 14 to move out of the incubator 23, saving manpower.

[0028] Replay Figure 1 In order to accurately control the temperature, a temperature sensor is provided in each heat chamber 21 to monitor the temperature inside each heat chamber 21; at the same time, a control component is installed on the outer wall of the box shell, and the control component includes a display screen that can display the operating parameters of the electric heating constant temperature incubator 23. The experimenter can enter instructions according to the indications on the display screen to change the current passing through the heating wire and change the temperature in the heat chamber 21.

[0029] In this embodiment, a voice-controlled circuit board is also provided, in which a voice-controlled circuit capable of controlling the current of the heating wire is embedded, and a microphone for collecting sound signals is adaptively provided on the outer wall of the box body 1. The control component includes a speech recognition module, which controls the temperature in the culture chamber 2 by collecting and recognizing sound signals.

[0030] The implementation principle of the electric constant temperature incubator with uniform temperature in the embodiment of the present application is as follows: before the hot air enters the incubator 23, it covers the incubator 23 through the air inlet channel to create a uniform heat environment and avoid uneven heat. After the heat flows into the incubator 23, it is dispersed in the incubator 23 through the perforations 241 to improve the uniformity of the hot air entering. At the same time, the hot air in the air inlet channel forms a thermal isolation layer outside the incubator 23 to reduce the loss of hot air in the incubator 23.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
