Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a static pressure box type temperature and humidity collection device used indoors. Background Art

[0002] The quality of finished cigarettes is mainly determined by the quality of the raw material tobacco. After selection, the quality of tobacco has a high quality. The key link in maintaining high quality is its storage environment. Due to the particularity of tobacco storage, tobacco storage has become a very important link in the production process of tobacco factories. One of the characteristics of tobacco is that it is easy to absorb a large amount of water in a high temperature environment, and release it when the temperature drops, condensing into water, causing a large number of microorganisms to multiply, causing large-scale burning, discoloration, deterioration, mildew, and insect bites of tobacco, causing serious economic losses. Therefore, in order to ensure the temperature and humidity balance requirements in the factory where tobacco is stored, especially the stability of the temperature and humidity indicators, it is necessary to measure the temperature and humidity of the factory environment in real time. However, since the temperature and humidity sensor is usually placed directly in the factory, the detection head on it is exposed to the outside, so when detecting temperature and humidity, the detection head is easily affected by air flow. For example, when there are people walking near the temperature and humidity sensor, air flow will be generated, which will affect the temperature and humidity sensor and reduce the accuracy of temperature and humidity collection.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 3As shown, the utility model provides a static pressure box type temperature and humidity collection device for indoor use to collect indoor temperature and humidity. In this embodiment, the static pressure box type temperature and humidity collection device includes:

[0029] The box body 1 comprises an air inlet 2 and an air outlet 3, wherein the air inlet 2 is arranged at the bottom of the box body 1, and the air outlet 3 is arranged at the top of the box body 1;

[0030] The baffle plate 4 is arranged inside the box body 1 and located above the air inlet 2, and a ventilation area 41 is formed between the baffle plate 4 and the inner wall of the box body 1 away from the air inlet 2;

[0031] The exhaust mechanism is arranged at the air outlet 3;

[0032] The temperature and humidity sensor 5 is arranged on the top of the box body 1 , and the detection end of the temperature and humidity sensor 5 is located inside the box body 1 .

[0033] By adopting this technical solution, an air inlet 2 is arranged at the bottom of the box body 1, an air outlet 3 is arranged at the top, an exhaust mechanism is arranged at the air outlet 3, and a baffle 4 is arranged above the air inlet 2 and below the air outlet 3, a ventilation area 41 is formed between the baffle 4 and the inner wall of the box body 1. When the exhaust mechanism is in operation, the airflow enters the interior of the box body 1 through the air inlet 2, and a dynamic pressure layer is formed below the baffle 4. After passing through the ventilation area 41, a static pressure layer with stable airflow is formed in the area above the baffle 4, thereby reducing airflow vibration. The detection end of the temperature sensor 5 is arranged in the static pressure layer, thereby reducing the influence of the detection end of the temperature and humidity sensor 5 caused by the circumference of the airflow, thereby improving the accuracy and reliability of indoor temperature and humidity collection.

[0034] Specifically, in this embodiment, the box body 1 is in the shape of a hollow rectangular parallelepiped, the air inlet 2 is rectangular and is arranged on one side of the bottom of the box body 1, and the air outlet 3 is arranged on the top of the box body 1 and is arranged on the same side as the air inlet 2. The baffle 4 is in the shape of a rectangular plate and is fixed inside the box body 1. The baffle 4 is located above the air inlet 2 and below the air outlet 3. A ventilation area 41 is formed between the baffle 4 and an inner side wall of the box body 1 away from the air inlet 2. After the airflow enters the internal area of ​​the box body 1 below the baffle 4 through the air inlet 2, the airflow is blocked by the baffle 4 and needs to pass through the ventilation area 41 to enter the area above the baffle 4 and be discharged from the air outlet 3. As a result, the direction of the airflow is changed, and a static pressure layer with stable airflow is formed above the baffle 4. The baffle 4 can also prevent the airflow from entering the air inlet 2 and being discharged directly from the air outlet 3 to form convection, causing unstable airflow in the box body 1.

[0035] The temperature and humidity sensor 5 is arranged at the top of the box 1 and its detection end is extended into the interior of the box 1, so that the detection end is located in the static pressure layer, thereby reducing the influence of airflow on the detection end of the temperature and humidity sensor 5 and improving the accuracy of indoor temperature and humidity collection. Specifically, a mounting hole 6 is arranged at the top of the box 1 and above the baffle 4 for mounting the temperature and humidity sensor 5.

[0036] It is worth noting that the temperature and humidity sensor 5 used in the present invention can be an integrated sensor, or a temperature sensor and a humidity sensor designed separately, as long as the temperature and humidity of the environment can be collected.

[0037] Furthermore, the area of ​​the ventilation area 41 is smaller than the area of ​​the air inlet 2. With this technical solution, the baffle 4 is arranged above the air inlet 2, and the ventilation area 41 is formed inside the box body 1 through the baffle 4. The area of ​​the ventilation area 41 is smaller than the area of ​​the air inlet 2, which can reduce the flow rate of the airflow passing through the ventilation area 41, and it is easy to form a static pressure layer above the baffle 4.

[0038] Furthermore, the bottom of the box body 1 is arranged to be inclined relative to the top.

[0039] Due to long-term use, a certain amount of condensation may be generated on the inner wall of the box 1, which may affect the accuracy of humidity collection. Therefore, by setting the bottom of the box 1 to be inclined relative to the top, the condensation can be discharged at the air inlet 2, further improving the accuracy and reliability of the measurement.

[0040] Optionally, the inclination angle α of the bottom relative to the top is 6°-10°.

[0041] With this technical solution, if the tilt angle is too large, the volume of the box body 1 will be too large, and if it is too small, the condensed water will not flow easily, which is not conducive to the discharge of the condensed water.

[0042] Furthermore, an air filter layer 8 is included, and the air filter layer 8 is arranged at the air inlet 2.

[0043] By adopting the above technical solution, the air filter layer 8 can filter impurities such as dust and tiny particles carried in the air, and keep the environment inside the box 1 clean.

[0044] Specifically, the air filter layer 8 can be fixed to the air inlet 2 by pulling or pasting. In this embodiment, a card slot is provided at the air inlet 2, and the air filter layer 8 is arranged in the card slot to fix the air filter layer 8 at the air inlet 2, so that the air filter layer 8 can be easily replaced.

[0045] Optionally, the air filter layer 8 is a nonwoven fabric. With this technical solution, the air filter layer 8 will not absorb the condensed water at the bottom of the box body 1 and affect the accuracy of humidity detection.

[0046] Furthermore, the inner walls of the box body 1 are all paved with insulation boards.

[0047] Specifically, the insulation board is laid on the inner wall of the box body 1, and corresponding openings are provided at the positions of the air inlet 2, the air outlet 3 and the mounting hole 6 of the temperature and humidity sensor 5. This technical solution can improve the stability of temperature and humidity detection.

[0048] Optionally, the material of the insulation board is extruded polystyrene foam for thermal insulation. With this technical solution, the extruded polystyrene foam for thermal insulation has the characteristics of extremely low water absorption and low thermal conductivity, which can ensure the stability of the measurement environment in the box 1 and improve the reliability of the measurement.

[0049] Optionally, the air extraction mechanism is an axial flow fan 7. More optionally, the axial flow fan 7 can be an ultra-quiet axial flow fan 7, thereby reducing environmental noise.

[0050] For example, in one embodiment of the present invention, in order to detachably fix the static pressure box-type temperature and humidity collection device to a wall in a room, a hook may be provided on the outer side wall of the box body 1 .

[0051] It is worth noting that in other embodiments of the utility model, other detachable connecting components can also be provided on the outer wall of the box body 1. For example, a female buckle is provided on the outer wall of the box body 1, and a male buckle is provided on the indoor wall. When in use, the female buckle is buckled onto the male buckle, and the static pressure box-type temperature and humidity collection device can also be detachably fixed to the wall. The specific selection can be made according to actual needs.

[0052] The utility model provides a static pressure box type temperature and humidity collection device for indoor use, which is arranged indoors to collect indoor temperature and humidity. An air inlet 2 is arranged at the bottom of the box body 1, an air outlet 3 and a temperature and humidity sensor 5 are arranged at the top, and an exhaust mechanism is arranged at the air outlet 3 for exhaust, wherein the air outlet 3 and the air inlet 2 are located on the same side of the box body 1, and a baffle 4 is arranged inside the box body 1 and between the air outlet 3 and the air inlet 2, and a ventilation area 41 is formed between the baffle 4 and the inner wall away from the box body 1. After the airflow enters from the air inlet 2, it is blocked by the baffle 4, and the path of the airflow is changed. The airflow enters from the ventilation area 41 to the top of the baffle 4, thereby forming a static pressure layer above the baffle 4. In addition, the area of ​​the air inlet 2 is set to be larger than the area of ​​the ventilation area 41, and the airflow of the static pressure layer formed above the baffle 4 is made more stable by reducing the air volume of the airflow. The detection end of the temperature and humidity sensor 5 is arranged in the static pressure layer, so that when the temperature and humidity sensor 5 collects the indoor temperature and humidity, the influence of the airflow on the detection end of the temperature and humidity sensor 5 can be reduced, and the accuracy and reliability of the temperature and humidity sensor 5 are improved. In addition, the bottom of the box 1 is arranged to be inclined relative to the top, which can ensure the air intake while also discharging the condensed water generated in the box 1 to a certain extent, further improving the reliability of temperature and humidity collection.
