[0026] Example 1

[0027] The following is combined with Figure 1-5 The utility model is further described as follows:

[0028] The utility model provides a novel constant temperature and humidity device 10, see Figure 1-5The novel constant temperature and humidity device 10 includes a constant temperature and humidity chamber 100, an automatic door 200 and a driving mechanism (not marked in the figure).

[0029] The automatic door 200 is used to open and close the constant temperature and humidity chamber 100. In this embodiment, the drive mechanism includes two sets of symmetrically arranged drive components (not marked in the figure). Specifically, one set of drive components is arranged on the top surface 110 of the constant temperature and humidity device, and the other set of drive components is arranged on the bottom surface 120 of the constant temperature and humidity device.

[0030] The structure of the driving assembly is not specifically limited, and the principle is that the automatic door 200 can be automatically driven to open and close relative to the constant temperature and humidity chamber 100. In this embodiment, specifically, the driving assembly includes a cylinder 311 and two elastic members 312 respectively arranged on both sides of the cylinder 311. The top surface 110 and the bottom surface 120 are both provided with a first receiving groove 130 for placing the cylinder 311, and the end of the telescopic rod of the cylinder 311 can contact the automatic door 200, and the shell of the cylinder 311 is connected to the first receiving groove 130. The top surface 110 and the bottom surface 120 are both provided with two second receiving grooves 140 for placing the elastic member 312, one end of the elastic member 312 is connected to the automatic door 200, and the end of the elastic member 312 away from the automatic door 200 is connected to the second receiving groove 140. When the automatic door 200 is closed in the constant temperature and humidity chamber 100, the elastic member 312 is in a stretched state.

[0031] In this embodiment, the extension and contraction direction of the cylinder 311 is arranged parallel to the extension and contraction direction of the elastic member 312 .

[0032] In the above arrangement, when the automatic door 200 needs to be opened, the cylinder 311 is started, and the telescopic rod of the cylinder 311 is extended to contact the automatic door 200. The automatic door 200 overcomes the pulling force of the elastic member 312 under the pushing action of the telescopic rod and leaves the constant temperature and humidity chamber 100, and the constant temperature and humidity chamber 100 is opened. When the automatic door 200 needs to be closed, the cylinder 311 is started again, and the telescopic rod of the cylinder 311 is retracted. The automatic door 200 approaches the constant temperature and humidity chamber 100 under the pulling force of the elastic member 312, and the constant temperature and humidity chamber 100 is closed. At this time, the pulling force of the elastic member 312 tightly pulls the automatic door 200, so that the automatic door 200 is closely attached to the constant temperature and humidity chamber 100.

[0033] In this embodiment, the door frame of the constant temperature and humidity chamber 100 is provided with a first sealing strip 150, and the surface of the automatic door 200 facing the constant temperature and humidity chamber 100 is provided with a second sealing strip 210, and the first sealing strip 150 is recessed with a limiting groove 151 for clamping the second sealing strip 210. Specifically, the direction perpendicular to the cylinder 311 is set as a preset direction, and the limiting groove 151 is in a "mouth" shape along the cross section parallel to the preset direction. In this embodiment, the telescopic rod of the cylinder 311 can be the first sealing strip 150, the limiting groove 151, and the second sealing strip 210; the end of the elastic member 312 away from the second receiving groove 140 passes through the first sealing strip 150, the limiting groove 151, and the second sealing strip 210 in sequence.

[0034] In this embodiment, when the constant temperature and humidity chamber 100 is closed, the second sealing strip 210 is naturally engaged in the limiting groove 151 of the first sealing strip 150, thereby further sealing the chamber. According to the arrangement of the first sealing strip 150 and the second sealing strip 210, a perfect sealing effect can be achieved, thereby completely isolating the chamber from the outside world.

[0035] To sum up, the new constant temperature and humidity device 10 provided in this embodiment has an ingenious structural design. It can not only realize the automatic opening and closing of the automatic door 200, but also has good sealing when the automatic door 200 is closed in the constant temperature and humidity chamber 100, and can completely isolate the outside world to avoid affecting the temperature and humidity in the chamber.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
