[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Example 1:

[0025] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 The hot and cold cycle all-in-one machine includes a box body 1, a partition 101 is fixedly installed in the box body 1, a high temperature experimental chamber 102 is provided above the partition 101 in the box body 1, and a low temperature experimental chamber 103 is provided below the partition 101. The side wall of the box body 1 is provided with a circulating air inlet device 4, and the top is provided with a circulating air outlet device 401. The high temperature experimental chamber 102 and the low temperature experimental chamber 103 are both provided with a temperature sensor 2. The machine also includes: a filter screen 5 provided on the circulating air inlet device 4; a lifting plate 6, which is lifted and connected in the circulating air inlet device 4 and is located in the On one side of the filter 5, a hollow cavity 602 is provided in the lifting plate 6, and an air jet hole 601 connected to the hollow cavity 602 is provided on the lifting plate 6. A booster pump 603, a dust suction pump 702, and a filter box 8 are fixedly installed on the box body 1. The output end of the booster pump 603 is connected to the hollow cavity 602 through an air pipe 604. A plurality of dust hoods 7 are equidistantly arranged on the upper and lower inner walls of the circulating air inlet device 4. The input end of the dust suction pump 702 is connected to the dust hood 7 through a conduit 1 701, and the output end is connected to the filter box 8 through a conduit 2 802.

[0026] The circulating air inlet device 4 is fixedly connected to a cylinder 605 , and the lifting plate 6 is fixedly connected to the output end of the cylinder 605 .

[0027] The filter box 8 includes an activated carbon filter 801 and an exhaust hole provided on the filter box 8 . A plurality of activated carbon filters 801 are provided, and the plurality of activated carbon filters 801 are detachably connected to the filter box 8 .

[0028] When in use, the specific implementation of the hot and cold cycle machine can refer to the utility model patent with application number 202022424146.2. During the test of the hot and cold cycle machine, when it is necessary to clean the dust and particulate matter in the filter holes of the filter 5, the booster pump 603 is first started to absorb external air, and then the gas is delivered to the hollow cavity 602 through the air pipe 604. Finally, the gas delivered into the hollow cavity 602 is sprayed toward the filter 5 through the air jet hole 601, thereby reversely cleaning the filter 5 and blowing out the dust particles in the filter holes of the filter 5;

[0029] When the filter 5 is reversely cleaned, the cylinder 605 is started, and the cylinder 605 drives the lifting plate 6 to move up and down in the circulating air inlet device 4, thereby performing a comprehensive reverse cleaning of the filter 5, so that all the dust particles in the filter holes of the filter 5 are blown out, which not only increases the convenience of cleaning the circulating air inlet device 4, but also increases the convenience of using the hot and cold cycle machine. At the same time, the dust suction pump 702 is started, and the dust suction pump 702 generates negative pressure in the dust hood 7, thereby sucking the dust particles blown out of the filter holes of the filter 5 into the dust hood 7, and then passing through the conduit one by one. 701 and conduit 2 802 transport it into the filter box 8. One-way valves are set on conduit 1 701 and conduit 2 802, so that when the gas passes through the filter box 8, it contacts multiple activated carbon filters 801 in sequence. Because the activated carbon has a developed void structure and abundant microporous tissue inside, these microporous tissues have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas. The purified gas can then be discharged to the outside through the exhaust hole;

[0030] In summary, by sucking the dust particles blown out of the filter holes of the filter 5 into the filter box 8 for filtration, it is prevented that the fine dust particles are scattered around and cause pollution to the environment.

[0031] It should be noted that the air delivery pipe 604 is a stretchable and retractable hose, so the air delivery pipe 604 will not interfere with the up and down movement of the lifting plate 6 in the circulating air inlet device 4;

[0032] During production, in order to prevent the air jet hole 601 from being blocked by dust particles, which would affect the cleaning of dust and particles in the mesh of the filter 5 , a microfiber filter can be provided at the input end of the booster pump 603 .

[0033] Example 2:

[0034] Reference Figure 3 , a hot and cold cycle all-in-one machine is basically the same as Example 1. Furthermore, an upper sealing plate 302 is provided above the partition 101 and a lower sealing plate 301 is provided below the partition 101. The upper sealing plate 302 and the lower sealing plate 301 are fixedly connected by a connecting rod and are used to close the openings provided on the partition 101. A placement groove 303 is provided on the lower sealing plate 301. The connecting rod is slidably connected to the partition 101, and the lower sealing plate 301 is lifted and connected in the low-temperature experimental chamber 103.

[0035] An electric telescopic rod 3 is fixedly installed in the low-temperature experimental chamber 103 , and the lower sealing plate 301 is fixedly connected to the output end of the electric telescopic rod 3 .

[0036] When it is necessary to move the test material placed in the placement groove 303 from the low-temperature experimental chamber 103 to the high-temperature experimental chamber 102, the electric telescopic rod 3 is first started. The electric telescopic rod 3 pushes the lower sealing plate 301 to drive the test material in the placement groove 303 to move upward. At the same time, when the lower sealing plate 301 moves upward, it can drive the upper sealing plate 302 to move upward synchronously, so that it opens the opening on the partition 101. At this time, the placement groove 303 can be moved into the high-temperature experimental chamber 102 through the opening of the partition 101 until the lower sealing plate 301 fits into the partition 101, thereby closing the opening on the partition 101.

[0037] When it is necessary to return to the low-temperature experimental chamber 103, the electric telescopic rod 3 is started again, and the electric telescopic rod 3 drives the lower sealing plate 301 to move downward, so that it opens the opening on the partition 101. At the same time, when the lower sealing plate 301 moves downward, the placement groove 303 and the upper sealing plate 302 move downward synchronously with the lower sealing plate 301. At this time, the placement groove 303 can return to the low-temperature experimental chamber 103 through the opening of the partition 101 until the upper sealing plate 302 fits into the partition 101, thereby closing the opening on the partition 101.

[0038] In summary, when the placement slot 303 is moved into any experimental chamber, the opening on the partition 101 is sealed by the sealing plate, thereby effectively reducing the impact of the temperature between the two experimental chambers. Through the setting of the electric telescopic rod 3, the test material placed in the placement slot 303 can be adjusted according to needs, thereby increasing the convenience of using the hot and cold cycler.

[0039] Example 3:

[0040] Reference Figure 6 , a hot and cold cycle all-in-one machine, which is basically the same as that in Example 1, and furthermore, a plurality of activated carbon filters 801 are inserted into the filter box 8;

[0041] By connecting the activated carbon filter 801 to the filter box 8 in a pluggable and removable manner, the following advantages are achieved:

[0042] Easy installation and removal: When the activated carbon filter 801 needs to be replaced, the old activated carbon filter 801 can be easily pulled out of the filter box 8 and then a new activated carbon filter 801 can be inserted, thereby making maintenance and replacement of the activated carbon filter 801 quick and easy without the need for complicated tools and operations;

[0043] High flexibility: according to different usage requirements, activated carbon filter screens 801 of different specifications, materials or filtering performance can be selected for plugging in, so that the filtering performance of the filter box 8 can be adjusted according to the needs, thereby meeting different work requirements.
