Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a ventilated wet and dry meter that can automatically replenish water. Background Technology

[0002] As a core instrument in meteorological observation, environmental monitoring, and laboratory humidity measurement, the ventilated hygrometer works by detecting humidity through a wet-bulb and dry-bulb thermometer inside the ventilated structure. The cotton cloth covering the surface of the wet-bulb thermometer needs to be continuously immersed in water. The relative humidity of the environment is calculated by utilizing the temperature difference caused by the heat absorbed by the evaporation of water and combining it with the dry-bulb temperature. Therefore, ensuring the continuous moisture of the wet-bulb cotton cloth is a key prerequisite for the stable and accurate operation of the ventilated hygrometer.

[0003] Existing ventilated wet and dry bulb thermometers are typically equipped with a water storage device (such as a water tank or trough) to work with the thermometer. However, due to limitations in the overall size of the instrument and the need for water pollution control, the volume of these storage devices is generally small, resulting in limited water storage capacity. In actual use, as the moisture on the wet bulb surface continues to evaporate, the water in the storage device is rapidly consumed. When the water is depleted, it needs to be manually replenished in a timely manner; otherwise, the instrument will malfunction. However, the water consumption rate varies significantly under different environmental conditions (such as differences in temperature, wind speed, and humidity). Operators need to check the water level and replenish the water periodically, which not only increases daily maintenance costs and labor intensity but also may interfere with the airflow environment around the ventilation structure, thereby affecting the measurement accuracy of the wet and dry bulb thermometer. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the purpose of this utility model is to provide a ventilated wet and dry meter that can automatically replenish water.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 3 As shown, according to one embodiment of the present invention, a ventilated wet / dry meter with automatic water replenishment includes a fixed base 1, a ventilated structure 2 and an automatic water replenishment device 3 installed on the fixed base 1. The automatic water replenishment device 3 includes a water storage bottle 31 installed on the fixed base 1 and a water tank 32 connected to the ventilated structure 2. The water storage bottle 31 is connected to the water tank 32 through a water inlet pipe 33 and a water seal pipe 34. The portion of the water seal pipe 34 located in the water tank 32 has a slanted cut 35 for switching the water storage bottle 31 to be sealed or ventilated, thereby realizing the water level control of the water tank 32.

[0019] In this embodiment, an automatic water level control mechanism with a purely mechanical structure is constructed through the innovative design of the oblique cut 35 of the water seal pipe 34. When the water level in the water tank 32 is lower than the set value, the oblique cut 35 is exposed to allow air to pass through the water storage bottle 31, and the water flows into the water tank 32 automatically under the action of air pressure difference. When the water level reaches the set height, the oblique cut 35 is submerged by water to form a seal, and the water storage bottle 31 stops replenishing water. The water level can be kept accurate and constant without the need for electric drive, which effectively solves the core pain points of traditional wet and dry meters that require frequent manual water replenishment and water level fluctuations that affect measurement accuracy. It ensures the continuous humid state of the wet bulb thermometer and provides a foundation for long-term continuous and stable measurement.

[0020] In the above embodiment, preferably, a water pipe switch 36 is provided on the water inlet pipe 33 and the water seal pipe 34 respectively, and the water pipe switch 36 is connected in series on the pipe section near the water storage bottle 31.

[0021] In this embodiment, the water pipe switch 36 enables independent control of the water supply path. When the equipment is being transported, maintained, or when water supply is not required, the switch can be turned off to cut off the water flow, preventing water leakage or accidental outflow from the water storage bottle 31. At the same time, it can quickly cut off the water supply when replacing the water storage bottle 31 or cleaning the water tank 32, improving operational safety and convenience, and further optimizing the user experience and maintenance efficiency of the equipment.

[0022] In any of the above embodiments, preferably, the water storage bottle 31 includes a bottle body 311 and a bottle cap 312 mounted on the bottle body 311, the bottle body 311 is hinged to the fixed base 1, and the bottle cap 312 is threadedly connected to the bottle body 311.

[0023] In this embodiment, the hinged design of the bottle body 311 and the fixed base 1 allows the water storage bottle 31 to be flipped around the hinge point. When adding water, there is no need to disassemble the overall structure; simply flipping the bottle body 311 is sufficient for convenient water replenishment. The threaded connection between the bottle cap 312 and the bottle body 311 ensures the sealing performance of the water storage bottle 31, preventing leakage during transportation or flipping. At the same time, the threaded connection structure is stable and facilitates the disassembly and assembly of the bottle cap 312 for cleaning the inside of the bottle body 311, thus balancing ease of operation and sealing reliability.

[0024] In the above embodiments, preferably, the bottle body 311 is a transparent bottle body 311 or the bottom of the bottle body 311 is a transparent bottle bottom 38, for direct observation of the water level inside the bottle.

[0025] In this embodiment, the design of the transparent bottle body 311 or the transparent bottle bottom 38 allows the operator to directly observe the remaining water level inside the water storage bottle 31 without disassembling it. This enables the operator to promptly detect and replenish the water when it is insufficient, avoiding measurement interruptions due to water shortage. It also reduces the operational hassle of frequently disassembling and assembling the water storage bottle 31, improving the convenience of equipment use and the continuity of measurement.

[0026] In any of the above embodiments, preferably, the automatic water replenishment device 3 further includes a water tank cover 37, which is fixed to the water tank 32 by screws to prevent the water in the water tank 32 from evaporating and being contaminated by dust in the air.

[0027] In this embodiment, the water tank cover 37 can effectively reduce the ineffective evaporation of water in the water tank 32, extend the water replenishment interval, and reduce the water replenishment frequency. On the other hand, it can prevent dust and impurities in the air from entering the water tank 32, avoid water pollution and blockage of the water seal pipe 34 and the water inlet pipe 33, and prevent the gauze of the wet bulb thermometer from being contaminated, thus ensuring the cleanliness and measurement accuracy of the measuring element and extending the maintenance cycle and service life of the equipment.

[0028] In any of the above embodiments, preferably, the fixing base 1 includes a U-shaped base 11 and a fixing cover 12 fixed on the U-shaped base 11, the ventilation structure 2 is installed on the U-shaped base 11, a U-shaped bracket 13 is formed on the fixing cover 12, and the water storage bottle 31 is hinged to the U-shaped bracket 13.

[0029] In this embodiment, the U-shaped base 11 provides a stable installation foundation for the ventilation structure 2. It has high structural strength and good support stability, which can effectively fix the ventilation structure 2 and reduce vibration interference during the measurement process. The U-shaped bracket 13 integrally formed on the fixed cover 12 provides a precise hinge installation position for the water storage bottle 31, ensuring that the water storage bottle 31 can be flipped smoothly. At the same time, the symmetry of the U-shaped structure makes the water storage bottle 31 bear force evenly, improving the stability and assembly accuracy of the overall structure, and making the equipment layout more reasonable and compact.

[0030] In any of the above embodiments, preferably, the ventilation structure 2 includes a housing 21, a wet and dry bulb thermometer 22 installed in the housing 21, and a fan 23 connected to the housing 21. The housing 21 is provided with an air inlet 24 and an air outlet 25. The air outlet 25 is connected to the fan 23, and the wet and dry bulb thermometer 22 is installed at the air inlet 24.

[0031] In this embodiment, the fan 23 creates negative pressure through the air outlet 25, causing external air to flow in at a uniform speed from the air inlet 24 and directly contact the temperature sensing element of the wet and dry bulb thermometer 22. This ensures stable airflow and full contact with the temperature sensing element, reducing the impact of environmental airflow turbulence on the measurement results. The installation design at the air inlet 24 enables the temperature sensing element to respond quickly to changes in environmental temperature and humidity, improving the measurement response speed. At the same time, the housing 21 protects the thermometer and airflow channel, preventing external debris and radiation interference, further ensuring the accuracy of the measurement data.

[0032] In any of the above embodiments, preferably, it further includes a tripod support frame 4 and a tripod fixing frame 5, with a fixing block 6 provided on each leg of the tripod support frame 4, and each fixing block 6 being connected to the tripod fixing frame 5 by a pin to enhance the support stability of the tripod support frame 4.

[0033] In this embodiment, the tripod support frame 4 and the tripod fixing frame 5 are connected by fixing blocks 6 and pins to form a stable triangular support structure. The pin connection ensures the connection strength of each component of the support, effectively distributes the weight of the equipment, and improves the overall wind resistance and terrain adaptability. Even on uneven ground or in environments with slight vibrations, the equipment can be placed stably, avoiding measurement errors caused by equipment shaking. This broadens the applicable scenarios of the equipment, enabling it to meet the usage needs of various complex environments such as meteorological observation and field scientific research.

[0034] The ventilated hygrometer with automatic water replenishment provided by this utility model combines mechanical automatic water level control with stable airflow temperature and humidity measurement in a synergistic design. The specific working principle is as follows: I. Core Working Mechanism of Automatic Water Replenishment The water storage bottle 31 is connected to the water tank 32 through a dual passage of inlet pipe 33 and water seal pipe 34. Its core control relies on the oblique cut 35 structure at the end of the water seal pipe 34: In the initial state, the water level in the water tank 32 is at the set height, the oblique cut 35 is completely submerged by water, and a sealed space is formed inside the water storage bottle 31. The air pressure is balanced with the outside, and the water cannot flow out due to the air pressure. When the water in the water tank 32 decreases due to absorption by the wet-bulb thermometer gauze and natural evaporation, and the water level drops below the oblique cut 35, the oblique cut 35 is exposed to the air, the water storage bottle 31 is ventilated with the outside, the internal air pressure decreases, and the water in the water storage bottle 31 automatically flows into the water tank 32 through the inlet pipe 33 under the action of atmospheric pressure. Until the water level rises back to the set height, the oblique cut 35 is submerged by water again, the water storage bottle 31 returns to the sealed state, and the water replenishment process automatically stops. Through this cycle, the water level in tank 32 is always maintained at the optimal wet height required for the wet-bulb thermometer gauze, achieving continuous water replenishment without manual intervention.

[0035] II. Working Mechanism of Temperature and Humidity Measurement In the ventilation structure 2, after the fan 23 starts, it creates negative pressure through the air outlet 25, driving external air to flow in at a constant speed from the air inlet 24 of the housing 21. The airflow directly passes through the temperature sensing element of the wet and dry bulb thermometer 22 installed at the air inlet 24. The gauze of the wet bulb thermometer is always in contact with the water in the water tank 32 (it is kept moist due to the automatic water replenishment mechanism). When the airflow passes through, the water on the surface of the wet bulb evaporates and absorbs heat, causing the wet bulb temperature to be lower than the dry bulb temperature, and a temperature difference is formed between the two. Based on the temperature and humidity conversion principle, combined with the stable airflow provided by the fan 23 to avoid environmental radiation and turbulence interference, the relative humidity of the environment can be accurately calculated by the difference between the dry bulb temperature and the wet bulb temperature.

[0036] III. Collaborative Working Logic of Auxiliary Structures The water pipe switch 36 can manually control the opening and closing of the water inlet pipe 33 and the water seal pipe 34. The switch can be closed during transportation or maintenance to prevent water leakage from the water storage bottle 31. It can be opened to restore automatic control when water is replenished. The cover of the water tank 32 reduces the ineffective evaporation of water in the water tank 32, while preventing dust from contaminating the water quality and ensuring the cleanliness of the gauze and the water replenishment cycle. The transparent design of the water storage bottle 31 makes it easy to observe the water volume in real time. The hinged installation allows it to be flipped for water replenishment, and the threaded cap 312 ensures a leak-proof seal. The tripod support frame 4 is connected to the tripod fixing frame 5 through the fixing block 6 and the pin to form a stable support structure, which prevents the equipment from shaking and affecting the stability of the airflow, thereby ensuring the measurement accuracy.

[0037] IV. Overall Collaborative Logic The automatic water replenishment mechanism provides continuous and stable humid conditions for the wet-bulb thermometer, solving the problem of measurement interruption or decreased accuracy caused by water shortage in traditional equipment; the stable airflow driven by fan 23 eliminates the interference of ambient airflow fluctuations on the temperature sensing element, making the dry and wet-bulb temperature difference more accurate; each auxiliary structure realizes protection, convenient operation and stable support around the core function, ultimately achieving the core goal of continuous and accurate measurement for a long time without frequent manual intervention.
