Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature and humidity weighing systems, in particular to a constant temperature and humidity weighing system with a built-in balance. Background Art

[0002] The constant temperature and humidity weighing system is a device that performs high-precision weighing under specific temperature and humidity conditions. It is a system that balances and weighs samples by placing a high-precision electronic balance in a high-precision constant temperature and humidity chamber. The system controls the temperature and humidity in the chamber to ensure the stability of environmental factors during the weighing process, thereby improving the accuracy and reliability of the weighing.

[0003] As disclosed in the Chinese patent: An automatic constant temperature and humidity weighing system for a high-temperature ashing device, application number: CN202320136882.9, comprising a high-temperature ashing box body, a constant temperature and humidity air conditioner inner body and an electronic balance body, the front of the high-temperature ashing box body is open, the constant temperature and humidity air conditioner inner body is located at the inner top of the high-temperature ashing box body, and the electronic balance body is located at the inner bottom of the high-temperature ashing box body. The beneficial effect is that the utility model can detachably fix the electronic balance body and the constant temperature and humidity air conditioner inner body to the high-temperature ashing box body by means of vertical sliding fit between the matching seat and the matching groove and horizontal sliding fit between the limit rod and the limit hole. The installation and fixing method of the electronic balance body and the constant temperature and humidity air conditioner inner body inside the high-temperature ashing box body is simple and easy to operate, which facilitates the rapid installation and layout of the electronic balance body and the constant temperature and humidity air conditioner inner body in the high-temperature ashing box body.

[0004] However, in the above technical solution, the constant temperature and humidity weighing system is a device for high-precision weighing. When weighing, the temperature and humidity need to be controlled through the blowing cycle of the constant temperature and humidity air conditioner. Although the blowing of the constant temperature and humidity air conditioner is small, it will inevitably affect the materials and reduce the accuracy of the weighing results. At the same time, the staff needs to place and take the materials back and forth when weighing. In this process, static electricity will inevitably be generated inside the constant temperature and humidity weighing system and on the materials. These electrostatic charges may affect the weighing accuracy of the electronic balance. Moreover, in a constant temperature and humidity experimental environment, static electricity may cause air ionization or generate electrostatic sparks, which may cause changes in local temperature and humidity, thereby interfering with the experimental results and reducing the accuracy of the weighing results. Utility Model Content

[0005] The main object of the present utility model is to provide a constant temperature and humidity weighing system with an in-built balance, which can effectively solve the problem that in the background art, the constant temperature and humidity weighing system is a device for high-precision weighing. When weighing, the temperature and humidity need to be controlled through the blowing cycle of the constant temperature and humidity air conditioner. Although the blowing of the constant temperature and humidity air conditioner is tiny, it will inevitably affect the material, reducing the accuracy of the weighing result. At the same time, when the staff is weighing, they need to place and pick up the material back and forth. During this process, static electricity will inevitably be generated inside the constant temperature and humidity weighing system and on the material. These static charges may affect the weighing accuracy of the electronic balance. Moreover, in the constant temperature and humidity experimental environment, static electricity may cause air ionization or static sparks, which may cause local temperature and humidity changes, thus interfering with the experimental results and reducing the accuracy of the weighing result.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

An electronic balance and a buckling groove are provided on the sliding plate. A plurality of ion blowers are provided on one side of the top surface of the constant temperature and humidity tank. A first rotating shutter is rotatably provided on one side of the constant temperature and humidity tank. An observation window is provided on the first rotating shutter, and a rubber glove operation opening is provided on the observation window.

[0008] Preferably, the first sliding groove is located inside one side below the constant temperature and humidity tank.

[0009] Preferably, the electronic balance includes a balance main body, and a weighing placement plate is provided on the balance main body.

[0010] Preferably, a protective frame is fixedly provided on one side of the balance main body close to the weighing placement plate, and a second rotating shutter is rotatably provided on one side of the protective frame.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] (1) When the utility model is in use, first start the thermostatic and humidistatic air conditioner, control the temperature and humidity inside the thermostatic and humidistatic tank through the thermostatic and humidistatic air conditioner, then use the baffle to shield the upper part of the weighing placement tray, then put the material into the thermostatic and humidistatic tank 2, and close the first rotating shutter. Then start the ion blower to eliminate the static electricity on the weighing placement tray and the balance body. At the same time, pick up the material through the rubber glove operation port and turn the material over repeatedly to eliminate the static electricity on the material by the ion blower. After the static electricity elimination is completed, use the push-pull plate to return the baffle to its original position, then place the material on the weighing placement tray, and then close the second rotating shutter to seal the protective frame to prevent the material from being affected by the blowing of the thermostatic and humidistatic air conditioner during weighing, resulting in inaccurate weighing results. It can effectively prevent the influence of static electricity and the blowing of the thermostatic and humidistatic air conditioner on the weighing result and improve the accuracy of the weighing result.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown Figures 1 to 3 in the figure, a constant temperature and humidity weighing system with a built-in balance includes a base 1. A constant temperature and humidity tank 2 and a constant temperature and humidity air conditioner 3 are arranged on the base 1. A first chute 4 is arranged in the constant temperature and humidity tank 2. A sliding plate 5 is slidably arranged in the first chute 4. An electronic balance 6 and a buckling groove 7 are arranged on the sliding plate 5. A plurality of ion blowers 8 are arranged on one side of the top surface of the constant temperature and humidity tank 2. A first rotating shutter 9 is rotatably arranged on one side of the constant temperature and humidity tank 2. An observation window 10 is arranged on the first rotating shutter 9. A rubber glove operation port 11 is arranged on the observation window 10.

[0024] As shown Figure 4 in another embodiment of the present utility model, the electronic balance 6 includes a balance main body 601, and a weighing placement tray 602 is arranged on the balance main body 601;

[0025] A protective frame 603 is fixedly arranged on one side of the balance main body 601 close to the weighing placement tray 602. A second rotating shutter 604 is rotatably arranged on one side of the protective frame 603;

[0026] A second chute 605 is arranged on one side above the protective frame 603. A baffle 606 is slidably arranged in the second chute 605. A push-pull plate 607 is arranged on the baffle 606;

[0027] When it is necessary to eliminate the static electricity on the balance main body 601 and the weighing placement tray 602 through the ion blower 8, first, the baffle 606 is moved to one side along the track of the second chute 605 through the push-pull plate 607. At this time, the baffle 606 will no longer shield the upper part of the weighing placement tray 602. Then, the static electricity on the weighing placement tray 602 and the part of the balance main body 601 close to the weighing placement tray 602 can be eliminated through the ion blower 8. When the static electricity elimination at the weighing placement tray 602 is completed, the baffle 606 is returned to its original position through the push-pull plate 607. At this time, the baffle 606 will shield the upper part of the weighing placement tray 602. Subsequently, the ion blower 8 can eliminate the static electricity at other places of the balance main body 601 temporarily shielded by the baffle 606. When weighing is required, the material is placed on the weighing placement tray 602, and then the second rotating shutter 604 is closed to seal the protective frame 603, preventing the material from being affected by the blowing of the constant temperature and humidity air conditioner 3 during the weighing process, resulting in inaccurate weighing results.

[0028] The working principle of the constant temperature and humidity weighing system with a built-in balance:

[0029] In use, first start the constant temperature and humidity air conditioner 3, control the temperature and humidity inside the constant temperature and humidity tank 2 through the constant temperature and humidity air conditioner 3, then move the baffle 606 along the track of the second chute 605 to one side by the push-pull plate 607, so that the baffle 606 no longer shields above the weighing placement plate 602. Subsequently, place the material into the constant temperature and humidity tank 2, and close the first rotating shutter 9. Then start the ion blower 8 to eliminate the static electricity on the weighing placement plate 602 and the balance body 601 through the ion blower 8. At the same time, pick up the material through the rubber glove operation port 11 and turn the material over repeatedly, and the ion blower 8 also eliminates the static electricity on the material. After the static electricity elimination is completed, make the baffle 606 return to its original position through the push-pull plate 607. Then place the material on the weighing placement plate 602, and then close the second rotating shutter 604 to enclose the protective frame 603, preventing the material from being affected by the blowing of the constant temperature and humidity air conditioner 3 during weighing, resulting in inaccurate weighing results. It can effectively prevent the influence of static electricity and the blowing of the constant temperature and humidity air conditioner 3 on the weighing result and improve the accuracy of the weighing result.

For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
