DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The energy-saving IVC host for automatically adjusting operating parameters in this embodiment includes an IVC host body 1. A self-adjusting mechanism 2 for adjusting the operating state is provided on the right side of the IVC host body 1. An experimental box 3 is connected to the right side of the self-adjusting mechanism 2. A temperature regulating mechanism 4 for adjusting the temperature is provided on the right side of the experimental box 3. The electrical components appearing in the text are all electrically connected to the main controller and the power supply.

The industrial power interface is connected to power on the device, and the PLC system controls the entire device to operate as expected.

[0024] See also Figure 2-3 In order to automatically adjust the pressure and humidity in the experimental box 3, the self-adjusting mechanism 2 in this embodiment includes a first three-way pipe 207 and a second three-way pipe 211 connected to the right side of the IVC main body 1, the upper end and the lower end of the first three-way pipe 207 are connected to the air inlet pipe 204, and the air inlet pipe 204 is connected to the left side of the experimental box 3, and the outer sides of the two air inlet pipes 204 are fixed with a first solenoid valve 208, the upper end and the lower end of the second three-way pipe 211 are connected to the air outlet pipe 210, and the air outlet pipe 210 is connected to the left side of the experimental box 3, and the outer sides of the two air outlet pipes 210 are fixed with a second solenoid valve 209, and the interior of the experimental box 3 is fixed with a partition 206, and the interior of the experimental box 3 A first pressure sensor 201 and a second pressure sensor 203 are fixed to the left wall of the cavity, a first humidity sensor 202 is fixed to the top wall of the inner cavity of the partition 206, and a second humidity sensor 205 is fixed to the top wall of the inner cavity of the experimental box 3. When the pressure sensor and the humidity sensor detect that the pressure or humidity in the detection area does not reach the set data, the number of air intakes and exhausts of the experimental box 3 at the same time is adjusted by adjusting the number of intervals between the two closings of the corresponding first solenoid valve 208 and the second solenoid valve 209, thereby causing changes in the pressure and humidity in the experimental box 3, and then adjusting the temperature and humidity in the experimental box 3 to within the set numerical range.

[0025] In this embodiment, the second pressure sensor 203 and the first pressure sensor 201 are symmetrical to each other up and down with the central axis of the partition 206 as the symmetry line. A sealing gasket is fixed to the front of the partition 206. The left side of the experimental box 3 is provided with air inlet holes for connecting two air inlet pipes 204 respectively. The first humidity sensor 202 and the second humidity sensor 205 are both located close to the air inlet holes, so that they can obtain the humidity in the air as quickly as possible and make adjustments. The two air inlet holes are respectively located on the upper and lower sides of the partition 206. The left side of the experimental box 3 is provided with air outlet holes for connecting two air outlet pipes 210 respectively, and the two air outlet holes are respectively located on the upper and lower sides of the partition 206.

[0026] It should be noted that the self-adjusting mechanism 2 detects the pressure and humidity in the experimental box 3 in real time through the pressure sensor and the humidity sensor, so as to ensure that real-time adjustment can be performed when changes in the external environment affect the internal environment of the experimental box 3.

[0027] See also Figure 4 In order to automatically adjust the temperature in the experimental box 3, the temperature control mechanism 4 in this embodiment includes two temperature control boxes 403 fixed on the right side of the experimental box 3, and dustproof nets 406 are fixed on the right sides of the two temperature control boxes 403. The top wall and the bottom wall of the inner cavity of the temperature control box 403 are fixed with connecting blocks 404, and a fan 405 is fixed between the opposite sides of two adjacent connecting blocks 404. The top wall and the bottom wall of the inner cavity of the temperature control box 403 are fixed with heating boxes 401, and the left and right side walls of the inner cavity of the heating box 401 are fixed with no less than two heating tubes 402. The heating tubes 402 are arranged in the temperature control box 403 to avoid the heating tubes 402 directly roasting the animals and causing the animals to die when an error occurs in the system. The top wall of the inner cavity of the experimental box 3 and the upper surface of the dustproof net 406 are fixed with temperature sensors 407.

[0028] In this embodiment, a temperature regulating hole for connecting to the temperature regulating box 403 is opened on the right side of the experimental box 3. The temperature regulating box 403 is in the shape of a rectangular block which is hollow inside and missing on both sides. The heating box 401 is in the shape of a rectangular block which is hollow inside and missing on one side close to the fan 405. There are no less than two heating tubes 402 evenly distributed on the left and right side walls of the inner cavity of the heating box 401. The control method of this application is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. This application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0029] It should be noted that the temperature control mechanism 4 lowers the temperature in the experimental box 3 through the cooperation of the fan 405, and at the same time cooperates with the heating tube 402 to increase the temperature in the experimental box 3, and through the cooperation of the temperature sensor 407, it determines whether to increase or decrease the temperature of the experimental box 3 or not adjust it.

[0030] The working principle of the above embodiment is:

[0031] (1) After the IVC host body 1 is started, fresh air is transported to the inside of the experimental box 3 and dirty air is extracted through the first three-way pipe 207 and the second three-way pipe 211. At the same time, the data is adjusted on the IVC host body 1 and the required pressure and humidity of the experimental environment are set. During the experiment, when the first pressure sensor 201 and the first humidity sensor 202 detect that the pressure or humidity in the detection area drops below the set data, the first solenoid valve 208 on the lower side shortens the interval between its two closings, thereby increasing the number of air intakes, causing the pressure to rise while the humidity rises. When the pressure and humidity reach the appropriate set values, the closing interval of the second solenoid valve 209 on the lower side is changed to be consistent with that of the first solenoid valve 208 on the lower side, so that the experimental environment is maintained at the set pressure and humidity. When the first pressure sensor 201 and the first humidity sensor 202 detect that the pressure or humidity in the detection area rises above the set data, the second solenoid valve 209 on the lower side shortens the interval between its two closings, thereby increasing the number of air intakes, causing the pressure to drop and the humidity to drop. When the pressure and humidity reach the appropriate set values, the closing interval of the first solenoid valve 208 on the lower side is changed to be consistent with that of the second solenoid valve 209 on the lower side, so that the experimental environment is maintained at the set pressure and humidity. The second pressure sensor 203 and the second humidity sensor 205 detect the same data and perform similar operations. The self-adjusting mechanism 2 detects the pressure and humidity in the experimental box 3 in real time through the pressure sensor and the humidity sensor, thereby ensuring that real-time adjustments can be made when changes in the external environment affect the internal environment of the experimental box 3.

[0032] (2) When the upper temperature sensor 407 detects that the temperature is lower than the set value, the heating tube 402 in the upper temperature control box 403 is started, and the fan 405 is started. The fan 405 drives the outside air to pass through the dustproof net 406 and enter the interior of the upper temperature control box 403, and then is heated by the heating tube 402. The heated air then enters the experimental box 3 to increase the temperature inside it until the temperature inside the experimental box 3 rises to the set value. When the temperature is higher than the set value, only the fan 405 is started to reduce the temperature. The temperature control mechanism 4 reduces the temperature inside the experimental box 3 through the cooperation of the fan 405, and at the same time cooperates with the upper heating tube 402 so that it can also increase the temperature inside the experimental box 3, and through the cooperation of the temperature sensor 407, it is determined whether to increase or decrease the temperature of the experimental box 3 or not adjust it.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
