[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] As Figure 1 - Figure 3 shown, an anti-evaporation device 1 for cement mortar testing provided in this application includes:

[0029] A machine body 10, in which a test tank 11 is formed;

[0030] A humidity control module 30, which includes a temperature and humidity sensor 31, a humidifier 33 and an electric control device 35. The temperature and humidity sensor 31 is installed on the inner wall of the test tank 11, the humidifier 33 is connected to the inner wall of the test tank 11, and the electric control device 35 is electrically connected to the temperature and humidity sensor 31 and the humidifier 33.

[0031] In this system, a dedicated test tank is designed and constructed within the body 10. This test tank 11 not only has the basic function of accommodation but also can provide a stable and controllable test environment for various test materials.

[0032] To ensure that the temperature and humidity of the test environment reach the optimal state, a dedicated humidity control module 30 is also equipped in the system. This module consists of multiple key components, including a temperature and humidity sensor 31, a humidifier 33, and an electric control device 35. The temperature and humidity sensor 31 is precisely installed on the inner wall of the test tank 11 and can monitor and feedback the current temperature and humidity data inside the tank in real time. The humidifier 33 is connected to the inner wall of the test tank 11 through a pipeline and is responsible for injecting an appropriate amount of water vapor into the tank according to the need to adjust and maintain the required humidity level. The electric control device 35, as the core of the entire humidity control module 30, closely connects the temperature and humidity sensor 31 and the humidifier 33 through electrical connections to achieve intelligent control of the entire system.

[0033] In addition, this system also has a highly intelligent adjustment function. It can automatically adjust the temperature and humidity inside the test tank 11 according to the real-time state of the test materials at different stages and the changes in the external environment. This automatic adjustment mechanism ensures that the test materials are always in the optimal test environment, thereby improving the accuracy and reliability of the test. Through this intelligent temperature and humidity control, the system can provide a stable and controllable test environment for various sensitive materials, ensuring the scientific nature and effectiveness of the test results.

[0034] Furthermore, the number of the temperature and humidity sensors 31 is multiple, and the multiple temperature and humidity sensors 31 are connected to the inner wall of the test tank 11 at intervals along the horizontal direction.

[0035] To more precisely monitor and control the environmental conditions inside the test tank 11, the number of the temperature and humidity sensors 31 is set to be multiple. These temperature and humidity sensors 31 are evenly spaced and connected to the inner wall of the test tank 11 along the horizontal direction to ensure that the temperature and humidity conditions in all areas inside the test tank 11 can be comprehensively covered and monitored. In this way, the temperature and humidity data at different positions can be obtained in real time, providing more accurate and reliable environmental parameters for the experiment.

[0036] Inside the constant temperature and humidity chamber, multiple temperature and humidity sensors 31 are also installed. These sensors are carefully arranged at different positions in the chamber to ensure that the temperature and humidity changes in every corner of the chamber can be monitored in real time. Through this meticulous layout, it can be ensured that the environmental conditions inside the constant temperature and humidity chamber always remain within the set range, thus providing a stable and controllable test environment for various sensitive devices or materials. This real-time monitoring mechanism not only improves the accuracy of experimental data but also provides researchers with a more flexible and efficient means of controlling experimental conditions.

[0037] Furthermore, the number of humidifiers 33 is multiple, and multiple humidifiers 33 are connected to the inner wall of the test tank 11 at intervals in the horizontal or vertical direction.

[0038] Inside the test tank 11, multiple humidifiers 33 are distributed. The number of these humidifiers 33 is not one but multiple. They are orderly connected to the inner wall of the test tank 11 at intervals in the horizontal or vertical direction. This layout enables the humidifiers 33 to evenly cover the entire internal space of the test tank 11, thus ensuring a uniform humidity distribution in the test tank 11 and meeting the test requirements.

[0039] Furthermore, the humidifier 33 includes a water tank 311, an ultrasonic generator, an atomizing sheet, and a fan. The ultrasonic generator and the atomizing sheet are both arranged inside the water tank 311, and the fan is arranged at the water outlet of the water tank 311 and connected to the atomizing sheet.

[0040] The integrated ultrasonic humidifier 33 generates fine water mist particles through high-frequency vibration, which are evenly distributed throughout the chamber to quickly increase the humidity. The water tank 311 is used to store the water to be atomized. Usually, there is a water injection port and a water level indicator. At the water inlet, a filter is provided to filter impurities in the water to ensure clean water quality. The ultrasonic generator includes an oscillator, an oscillation circuit, and a control circuit. The oscillator converts electrical energy into mechanical energy to generate high-frequency vibration. The oscillation circuit provides a high-frequency electrical signal to drive the oscillator to work. The control circuit is responsible for controlling the working state of the oscillation circuit, including frequency adjustment, power adjustment, etc. The atomizing sheet is located at the bottom of the water tank 311 and is connected to the ultrasonic generator. It breaks up water molecules into fine water droplets through high-frequency vibration. The fan is used to blow out the atomized water mist to enhance the humidifying effect. The ultrasonic humidifier 33 has the characteristics of low noise, high energy efficiency, simple maintenance, and high safety. It can quickly atomize a large number of water molecules, with high humidifying efficiency and low energy consumption.

[0041] Furthermore, the humidifier 33 also includes a water temperature sensor, which is arranged inside the water tank 311 and is electrically connected to the electronic control device 35.

[0042] The water temperature sensor can monitor the water level in the water tank 311. When the water level is lower than the set value, it automatically stops working to prevent dry burning.

[0043] Furthermore, the body 10 is further provided with a film covering assembly 13. The film covering assembly 13 includes a film 131, a winding and unwinding roller 133 and a movable roller 135. On both opposite side walls of the body 10 where the opening of the test tank 11 is located, movable grooves 15 are formed. The movable grooves 15 extend in the horizontal direction. The winding and unwinding roller 133 is rotatably connected to one end of the movable groove 15. The film 131 is wound around the winding and unwinding roller 133. Both ends of the movable roller 135 are movably inserted into the movable groove 15. One end of the film 131 is connected to the movable roller 135. The movable roller 135 moves along the movable groove 15 to drive the film 131 to unwind or wind around the winding and unwinding roller 133. The film 131 is unwound to cover the opening of the test tank 11.

[0044] To ensure the accuracy and reliability during the test process, the body 10 is also specially designed with a film covering assembly 13. This assembly mainly includes three key parts: a film 131, a winding and unwinding roller 133 and a movable roller 135. Specifically, on both side walls of the opening of the test tank 11 of the body 10, movable grooves 15 are formed. These movable grooves 15 extend and are arranged in the horizontal direction for subsequent operations. The winding and unwinding roller 133 is rotatably connected to one end of the movable groove 15 so that the film 131 can be wound thereon. Both ends of the movable roller 135 are flexibly inserted into the movable groove 15 to ensure its free movement. One end of the film 131 is connected to the movable roller 135. By the movement of the movable roller 135 along the movable groove 15, the film 131 can be driven to unwind or wind around the winding and unwinding roller 133. In this way, the film 131 can be smoothly covered on the opening of the test tank 11 to ensure the environmental stability during the test process. The covering function of the plastic film 131 effectively reduces the water evaporation, especially in the initial stage of the test, to ensure that the initial state of the specimen is not affected. There is a film 131 tensioning mechanism to ensure that the film 131 is flat and adheres to the surface of the specimen, effectively reducing the water evaporation. After the test is over, the film 131 is automatically recovered for the next test.

[0045] Furthermore, the winding and unwinding roller 133 includes a core shaft and a spring sleeve. One end of the film 131 is connected to the core shaft. The spring sleeve is sleeved on the outer surface of the core shaft.

[0046] The core shaft is used to support and fix the material roll. It is usually made of metal material and has sufficient strength and rigidity. The spring sleeve is sleeved outside the core shaft and is internally provided with a spring or other elastic elements to provide a restoring force. The spring sleeve usually consists of two parts. One is a fixed sleeve fixed on the core shaft, and the other is a movable sleeve that can rotate relative to the fixed sleeve. The spring is installed between the fixed sleeve and the movable sleeve. When the material is unwound, the spring is stretched or compressed to store energy; when the material is rewound, the spring returns to its original state to provide a rewinding force. The restoring force of the spring or other elastic elements is used to realize the automatic rewinding of the material.

[0047] Furthermore, a plurality of pulleys 16 are connected to the bottom of the body 10 at intervals.

[0048] At the bottom of the mechanical device, a plurality of pulleys 16 are connected in an interval manner. These pulleys 16 are evenly distributed under the device, making the entire mechanical structure more stable and flexible. Each pulley 16 is carefully designed to ensure smooth rotation during use, thereby improving the operating efficiency of the entire machine. Through this interval connection method, the pulleys 16 do not interfere with each other, ensuring that each pulley 16 can independently perform its function and further enhancing the overall performance of the machine.

[0049] Furthermore, feet 17 are connected to the bottom of the body 10.

[0050] At the bottom of the mechanical device, several sturdy feet 17 are installed. These feet 17 not only support the entire mechanical structure but also ensure the stability of the equipment during operation, preventing displacement due to vibration or external impact. Each foot 17 is carefully designed to adapt to different ground conditions, ensuring that the mechanical device can operate normally in various environments. In addition, the material selection of the feet 17 also takes into account durability and corrosion resistance to extend the overall service life of the equipment.

[0051] Furthermore, an observation window 18 is provided on the side of the body 10.

[0052] On the side part of the mechanical device, an observation window 18 is specially designed and provided. This observation window 18 enables users to directly observe the internal operation conditions, providing an intuitive visual experience. Through this observation window 18, people can clearly observe how the various components inside the machine cooperate, thereby better understanding and monitoring the operating state of the device. This design not only increases the transparency of the mechanical device but also improves the operation convenience and safety of users.

However, it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present utility model.
