Description

Technical Field

[0001] This invention relates to the field of meteorological detection equipment technology, and more specifically, to a portable meteorological instrument and its method of use. Background Technology

[0002] Meteorological instruments are core equipment for collecting, recording, and analyzing meteorological parameters such as temperature, humidity, and wind speed. They are widely used in various scenarios, including outdoor exploration, geological exploration, agricultural planting, environmental monitoring, and daily travel. Their detection accuracy and portability directly determine the timeliness and practicality of meteorological data collection. With the increasing demand for outdoor travel and fieldwork, portable meteorological instruments, due to their small size and ease of carrying, are gradually replacing traditional large meteorological equipment and becoming the mainstream choice for outdoor scenarios. They can meet users' needs to obtain surrounding meteorological data anytime, anywhere, and avoid the risks of severe weather. These instruments need to balance comprehensive detection functions, structural stability, and portability and protection. They must be able to accurately collect multi-dimensional meteorological parameters, adapt to complex outdoor environments such as bumps, temperature changes, rain, snow, and dust, and be easy to store and carry without affecting the user's travel or work.

[0003] Current portable weather instruments typically consist of a small housing that can house temperature and humidity sensors and wind speed sensors. The housing has a detection port for the sensors to contact the external environment and collect meteorological parameters. To facilitate portability and save space, these instruments generally use thermal anemometers. The core components of a thermal anemometer are a heating element (usually a metal wire, metal film, or semiconductor) and a temperature sensing element. They measure wind speed by measuring the relationship between the "heat loss rate" and "wind speed." However, when detecting wind speed, because the anemometer's detection probe is located inside the housing, the heat energy located inside the housing is reduced during instrument operation. The wind speed sensor detection probe affects the normal wind speed detection and improves the detection accuracy of the wind speed sensor. However, the above-mentioned method of directly placing the wind speed sensor on the outside of the shell means that when the existing belt-carrying portable weather instrument is not in use, the temperature and humidity sensor and the protruding wind speed sensor detection probe are not only unprotected, but also easily collide with other hard objects during carrying, causing scratches on the probe surface, and even damage to the probe in severe cases. This increases the maintenance cost of the weather instrument and is also likely to affect the detection stability of the weather instrument. In addition, the protruding probe increases the overall size of the weather instrument and reduces the portability of the belt-carrying portable weather instrument.

[0004] In view of this, we propose a retractable and protective weather instrument that can be carried in clothing. Summary of the Invention

[0005] Technical problem to be solved: The purpose of this invention is to provide a portable weather instrument and its method of use, thereby solving the technical problems mentioned in the background art.

[0006] Technical Solution: In a first aspect, the present invention provides a portable weather instrument, including a shell and a button. A circuit board is fixed to the bottom surface inside the shell. A sealing cover is fixed to the top of the shell. A positioning block is fixed to the bottom surface of the sealing cover. A fixing screw is connected through the positioning block and the inside of the shell. A button is connected through the top surface of the sealing cover. A temperature and humidity sensor is provided on the bottom surface of the sealing cover. A second detection hole is opened through the inside of the sealing cover and is located on top of the temperature and humidity sensor. A sealing component is slidably connected to the top surface of the sealing cover. The sealing component is slidably sealed to the top of the second detection hole on the sealing cover. A charging indicator light and a charging communication interface are provided through the side wall of the shell. Multiple first detection holes are opened on the outer wall of the shell. Multiple sets of wind speed detection components are provided inside the shell, corresponding to the first detection holes. The wind speed detection components are used to detect the vector airflow wind speed in the direction of the corresponding first detection hole. A protective sleeve assembly is slidably sleeved on the bottom outer wall of the shell. The protective sleeve assembly is slidably sealed to the outer wall of the first detection hole and the charging communication interface. The sheath assembly includes a sleeve fitted onto the outer wall of the bottom end of the housing. Multiple push blocks are fixed to the inner wall of the sleeve, and the push blocks are slidably connected to the inside of the housing. Multiple fixing plates are fixed to the inner wall of the housing. A first sliding rod is connected to the bottom surface of the fixing plates, and the bottom end of the first sliding rod is connected to the bottom surface inside the housing. The push blocks are slidably fitted onto the outer wall of the first sliding rod. A first spring is fitted onto the outer wall of the first sliding rod, and the first spring is connected between the bottom surface of the fixing plate and the top surface of the push block. A lifting block is fixed to the top surface of the push block. A fixing ring is connected through the interior of the multiple lifting blocks. Multiple inclined top blocks are fitted onto the outer wall of the fixing ring. One side of the inclined top block is fitted against one side of the wind speed detection component. The inclined top block is used to obliquely push the wind speed detection component so that the wind speed detection component passes through and is spaced within the first detection hole, extending outwards from the outside of the housing. A stopper is located at the bottom end of the sealing component and passes through the inside of the housing. The sleeve rises to seal the first detection hole and the outer wall of the charging communication interface, causing the push block to rise and compress the first spring. The stopper moves to stop the push block on the bottom surface.

[0007] Furthermore, the sealing component includes a sealing push plate that slides against the top surface of the sealing cover, and a stop member that is an L-shaped locking bracket. The locking bracket is fixed to the bottom surface of the sealing push plate and slidably connected to the bottom of the sealing cover. The sealing push plate is moved to block the top of the second detection hole, and the locking bracket is pushed and moved by the sealing push plate and stopped at the bottom surface of the push block.

[0008] Furthermore, a baffle is fitted onto the outer wall of the push block, the baffle slides against the inner wall of the outer shell, and the baffle closes the opening inside the outer shell for the push block to slide.

[0009] Furthermore, the bottom surface of the outer shell is provided with through holes, and multiple through holes are provided corresponding to the first detection holes, with a gap provided between the wind speed detection component and the first detection holes; The sleeve slides downwards along the outer wall of the outer shell to form a pressure chamber between the bottom of the outer shell and the inside of the sleeve. The pressure chamber is connected to the inside of the outer shell through a through hole.

[0010] Furthermore, an isolation cover is fixed to the inner wall of the outer shell, the isolation cover is connected through the through hole and the first detection hole, and a wind speed detection component is connected through one side of the isolation cover; The wind speed detection component includes a wind speed sensor that runs through the inside of the isolation cover. One end of the wind speed sensor is fixed with a sloping push plate. A second slide rod runs through the inside of the sloping push plate. One end of the second slide rod is connected to the side wall of the isolation cover. A second spring is sleeved on the outer wall of the second slide rod. One side of the sloping push plate is a sloping push surface, which consists of an upper vertical surface, a sloping surface, and a lower vertical surface. A sloping top block is attached to one side of the sloping push surface of the sloping push plate.

[0011] Furthermore, the isolation cover has a funnel-shaped structure that is narrower at the top and wider at the bottom. An arc-shaped air guide plate is fixed to the inner wall of the isolation cover near the first detection hole. An air outlet channel is provided between the air guide plate and the inner wall of the isolation cover on the other side. An elastic telescopic rod is connected to one side of the wind speed sensor. A wind baffle ring is connected to one end of the elastic telescopic rod. The wind baffle ring is fitted between the inner wall of the isolation cover and the arc-shaped inner wall of the air guide plate. The inner wall of the wind baffle ring is spaced apart from the outer wall of the wind speed sensor. An air guide ring is fixed inside the first detection hole. The side of the air guide ring near the inside of the outer shell has a sloping structure. The side of the wind baffle ring has a sloping structure and is fitted with the sloping structure of the air guide ring. The elastic telescopic rod is retracted into the outer shell and moved horizontally through the wind speed sensor, so that the elastic telescopic rod pulls the wind baffle ring to move horizontally, so that the wind baffle ring and the air guide ring are spaced apart and a backflow groove is formed. The backflow groove is used to guide air into the inside of the wind speed sensor end.

[0012] Furthermore, a waterproof and breathable valve is connected through the inside of the sealing cover, and the bottom end of the waterproof and breathable valve is connected through the bottom end of the outer shell. The bottom end of the waterproof and breathable valve is connected through the air pressure chamber. A sealing ring is fixed on the bottom surface of the outer shell and fits against the inner wall of the sleeve.

[0013] Furthermore, the sheath assembly also includes a sealing ring fixed to the bottom surface inside the sleeve. The sealing ring is disposed at the bottom of multiple through holes and is used to fit and seal the bottom surface of the through holes. A rubber gasket is fixed inside the sealing ring.

[0014] Furthermore, the sheath assembly also includes rubber rings, which are fitted onto the outer wall of the sleeve, and multiple rubber rings are provided.

[0015] Secondly, this invention provides a method for using a portable weather instrument. The method of using the aforementioned portable weather instrument includes the following steps: S1, Push to unlock; The pusher plate on the sealing cover is slid, opening the second detection hole and causing the locking bracket to separate from the pusher block, releasing the stop on the pusher block; the compressed first spring pushes the pusher block to slide down along the first slide rod, the pusher block drives the baffle to slide down along the inner wall of the outer shell and pushes the sleeve to slide down along the outer wall of the outer shell, causing the sealing ring and rubber gasket to separate from the outer shell, the interior of the outer shell is connected to the air pressure chamber through the through hole, the volume of the air pressure chamber increases, creating a negative pressure inside the outer shell, and air enters the outer shell and the air pressure chamber through the waterproof and breathable valve; at the same time, the sleeve opens the first detection hole and the charging communication interface, and external air enters the air pressure chamber through the first detection hole, and can be connected to external charging or communication equipment through the charging communication interface, and the charging status can be observed through the charging indicator light; the inclined pusher block pushes the inclined pusher plate downward to move towards the isolation cover, and the wind speed sensor extends out of the outer shell through the first detection hole; S2, Start detection; Pressing the button activates the circuit board, which is electrically connected to the button, temperature and humidity sensor, wind speed sensor, and charging communication interface. Holding the sleeve, the entire instrument is raised above the head, with fingers resting on the rubber ring around the sleeve to improve stability, prevent slippage, and isolate hand temperature from interference with detection. The temperature and humidity sensor detects external temperature and humidity through the second detection hole, and multiple wind speed sensors detect external wind speed through first detection holes extending in multiple directions. The detection data is stored in the storage element of the circuit board. During detection, if moisture adheres to the inner wall of the first detection hole, pressing the outer shell and sleeve reduces the volume of the air pressure chamber. The sealing ring adheres to the inner wall of the sleeve to keep the air pressure chamber sealed, and the air in the air pressure chamber is ejected through the first detection hole to remove the moisture and ensure detection accuracy. S3, Pressure and Blockade; Pressing the outer shell causes it to retract into the sleeve. The pusher slides upward along the first slide rod and compresses the first spring, reducing the volume of the air pressure chamber. The air inside the chamber is first ejected through the first detection hole to clean it again, and to cool the wind speed sensor and remove any adhering dew. Pressing continues until the sleeve seals the first detection hole and the charging communication interface. The remaining air inside the chamber is discharged through the waterproof vent valve until the sealing ring adheres to the bottom surface of the sealed through hole. The pusher plate is pushed to seal the top surface of the second detection hole, and the locking bracket moves to stop the pusher block on the bottom surface, completing the instrument storage and protection. Collision protection is achieved through the rubber ring around the sleeve, ensuring the safety of the instrument.

[0016] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. By opening multiple first detection holes on the side wall of the outer shell, and correspondingly setting wind speed detection components inside, the sleeve simply slides down the outer wall of the outer shell, and multiple inclined blocks extend multiple sets of wind speed detection components from the first detection holes to realize vector airflow detection, improve the accuracy of wind speed data, and slide the sleeve up to retract the wind speed detection components into the outer shell, and seal the first detection holes and charging communication interface. It has strong protection when carried, effectively avoiding the damage of the detection probes in the wind speed detection components during the carrying of the weather instrument with clothing, ensuring the stability of the weather instrument with clothing, and further facilitating people to carry it when performing weather monitoring tasks outdoors.

[0017] 2. When the sleeve rises, it seals the first detection hole and the charging communication interface. At the same time, the push block compresses the first spring, and the stop of the sealing component moves the bottom surface of the stop push block to achieve linkage locking between the sheath assembly and the sealing component, ensuring the stability of the meteorological instrument in the storage state. When using the meteorological instrument, simply push the sealing component to separate the stop from the push block. The first spring resets and pushes the push block down, causing the sleeve to slide down and open the detection hole and interface. At the same time, the inclined top block descends to push out the wind speed detection component, unlocking the detection state. This improves the convenience of storage and detection switching operations for the belt-carried meteorological instrument.

[0018] 3. By fixing the temperature and humidity sensor to the bottom of the sealing cover and collecting the ambient temperature and humidity through the second detection hole, the sealing component is slidably connected to the top of the sealing cover, which can block the second detection hole and prevent the temperature and humidity sensor from being interfered with or damaged by the external environment when stored. This improves the protection effect of the temperature and humidity sensor of the portable weather instrument when it is being carried.

[0019] 4. Multiple through holes corresponding to the first detection hole are opened on the bottom surface of the outer shell. The gap between the wind speed detection component and the first detection hole is set to ensure smooth airflow and improve detection accuracy. When the sleeve slides down, the bottom end of the outer shell and the inside of the sleeve form an air pressure chamber. The air pressure chamber is connected to the inside of the outer shell through the through holes, providing a structural basis for airflow and self-cleaning. The air pressure chamber structure provides power for cleaning and protecting the wind speed sensor. The structure is simplified and the ease of use is improved.

[0020] 5. An isolation cover is fixed to the inner wall of the outer shell, which is connected between the through hole and the first detection hole. It provides a directional guiding channel for airflow. When the wind speed sensor is stored inside the outer shell, the air pressure chamber contracts and the internal air is discharged through the isolation cover first. The air cleans and protects the side wall of the wind speed sensor, preventing impurities from being introduced into the wind speed sensor after it is stored inside the outer shell and causing contamination to the electronic components installed inside the outer shell. This helps to improve the reliability of the meteorological instrument.

[0021] 6. An isolation cover with a funnel-shaped structure, narrow at the top and wide at the bottom, is used. Inside the isolation cover, air guides and wind deflectors are installed to guide airflow. When the pressure chamber decreases, the air in the pressure chamber gathers between the outer wall of the wind speed sensor and the inner wall of the wind deflector, increasing the wind speed passing through the outer wall of the wind speed sensor. The air is then discharged through the first detection hole, increasing the exhaust wind speed. Thus, when the wind speed sensor is stored, the air discharged from inside the isolation cover can quickly spray off the dew adhering to the surface of the wind speed sensor and spray it out through the first detection hole. This prevents the dew adhering to the side wall surface of the wind speed sensor from being introduced into the housing when it retracts into the housing, which would cause excessive moisture inside the meteorological instrument. This helps to further improve the reliability of the meteorological instrument's operation.

[0022] 7. When the wind speed sensor retracts further into the housing, the wind deflector ring and the air guide ring separate, forming a backflow groove between them. The backflow groove guides air into the wind speed sensor, and the accelerated air rapidly cools the metal wire inside the sensor that measures wind speed. The internal heat is then discharged through the first detection hole. The sleeve then completely seals the first detection hole to prevent the wind speed sensor from retracting further into the housing. When the meteorological instrument is in the retracted and sealed storage state, the overheated metal wire in the wind speed sensor has an excessive impact on the internal temperature of the meteorological instrument, causing the internal temperature of the meteorological instrument to rise rapidly in a short period of time. During subsequent carrying of the meteorological instrument, when it is placed in a pocket or storage bag, the internal heat is even more difficult to dissipate, which may affect the service life of the electronic components installed inside the meteorological instrument due to high temperature, or even cause damage. This ensures the reliable and stable operation of the meteorological instrument.

[0023] 8. The sealing cap is internally connected to a waterproof and breathable valve, and its bottom end is connected to the air pressure chamber to achieve air pressure balance between the inside of the air pressure chamber and the outside. This allows the air inside the air pressure chamber to continue to be discharged after the first detection hole is sealed, ensuring that the sleeve slides smoothly without jamming.

[0024] 9. The sealing ring of the sheath assembly is fixed to the bottom surface inside the sleeve and is set to correspond to the through hole. When stored, it fits snugly against the bottom surface of the closed through hole to prevent moisture and dust from entering. When not in use, the internal components are free from contamination. The sealing ring has a rubber pad fixed inside, which can be used to cushion the bottom surface of the outer shell to prevent the outer shell and the inside of the sleeve from colliding and to ensure the safety of the internal structure.

[0041] Example 1: Refer to Figures 1-12This invention provides a portable weather instrument, including a housing 100 and a button 300. A circuit board 900 is fixed to the bottom surface of the housing 100. A sealing cover 200 is fixedly sealed inside the top of the housing 100. A positioning block 230 is fixed to the bottom surface of the sealing cover 200. A fixing screw 800 is connected through the positioning block 230 to the inside of the housing 100. The button 300 is connected through the top surface of the sealing cover 200. A temperature and humidity sensor 400 is disposed on the bottom surface of the sealing cover 200. A second detection hole 210 is provided through the inside of the sealing cover 200 and is located on top of the temperature and humidity sensor 400. A sealing part is slidably connected to the top surface of the sealing cover 200. Component 220, the sealing component 220 slides on the sealing cover 200 to block the top of the second detection hole 210, the side wall of the outer shell 100 is provided with a charging indicator light 130 and a charging communication interface 140, the outer wall of the outer shell 100 is provided with a plurality of first detection holes 110, the inner wall of the outer shell 100 is provided with a plurality of wind speed detection components 500 corresponding to the first detection holes 110, the wind speed detection components 500 are used to detect the vector airflow wind speed in the direction corresponding to the first detection hole 110, the bottom outer wall of the outer shell 100 is slidably sleeved with a protective sleeve component 600, the protective sleeve component 600 slides on the outer wall of the outer shell 100 to block the first detection hole 110 and the outer wall of the charging communication interface 140; The sheath assembly 600 includes a sleeve 610 fitted onto the outer wall of the bottom end of the outer shell 100. Multiple push blocks 620 are fixed to the inner wall of the sleeve 610 and slidably connected to the interior of the outer shell 100. Multiple fixing plates 150 are fixed to the inner wall of the outer shell 100. A first sliding rod 160 is connected to the bottom surface of the fixing plate 150, and its bottom end is connected to the inner bottom surface of the outer shell 100. The push blocks 620 are slidably fitted onto the outer wall of the first sliding rod 160. A first spring 170 is fitted onto the outer wall of the first sliding rod 160 and is connected between the bottom surface of the fixing plate 150 and the top surface of the push blocks 620. A lifting block 670 is fixed to the top surface of the push blocks 620, and the multiple lifting blocks 670 are internally connected. A fixing ring 690 is connected, and multiple inclined top blocks 680 are sleeved and fixed on the outer wall of the fixing ring 690. One side of the inclined top block 680 is attached to one side of the wind speed detection component 500. The inclined top block 680 is used to push the wind speed detection component 500 at an angle so that the wind speed detection component 500 passes through and is gapped inside the first detection hole 110 and extends out of the outer shell 100. The bottom end of the sealing component 220 is a stop and passes through the inner shell 100. The sleeve 610 rises and blocks the first detection hole 110 and the outer wall of the charging communication interface 140 by rising on the outer wall of the outer shell 100, so that the push block 620 rises and compresses the first spring 170. The stop is stopped on the bottom surface of the push block 620 by translation. By fixing the temperature and humidity sensor 400 to the bottom surface of the sealing cover 200 and collecting ambient temperature and humidity through the second detection hole 210, the sealing component 220 is slidably connected to the top surface of the sealing cover 200, which can block the second detection hole 210, thus preventing the temperature and humidity sensor 400 from being interfered with or damaged by the external environment when stored, and improving the protection effect of the temperature and humidity sensor 400 of the portable weather instrument when it is carried. By opening multiple first detection holes 110 on the side wall of the outer shell 100, and correspondingly setting wind speed detection components 500 inside, the sleeve 610 simply slides down the outer wall of the outer shell 100, and multiple inclined top blocks 680 extend multiple sets of wind speed detection components 500 out of the first detection holes 110 to realize vector airflow detection, improve the accuracy of wind speed data, and slide the sleeve 610 upward to retract the wind speed detection components 500 into the outer shell, and seal the first detection holes 110 and the charging communication interface 140. It has strong protection when carried, effectively avoiding the damage of the detection probe in the wind speed detection component 500 during the carrying of the weather instrument with clothing, ensuring the stability of the weather instrument with clothing, and further facilitating people to carry it when performing weather monitoring tasks outside. When the sleeve 610 rises, it blocks the first detection hole 110 and the charging communication interface 140. At the same time, the push block 620 compresses the first spring 170, and the stop of the locking component 220 moves to stop the bottom surface of the push block 620, realizing the linkage locking between the protective sleeve assembly 600 and the locking component 220, ensuring the stability of the meteorological instrument in the storage state. When using the meteorological instrument, simply push the locking component 220 to separate the stop from the push block 620. The first spring 170 resets and pushes the push block 620 down, causing the sleeve 610 to slide down and open the detection hole and interface. At the same time, the inclined top block 680 descends to push out the wind speed detection component 500, unlocking the detection state, thus improving the convenience of the storage and detection switching operation of the belt-carried meteorological instrument.

[0042] In this embodiment, the sealing component 220 includes a sealing push plate 221 that slides against the top surface of the sealing cover 200, and a stop member that is an L-shaped locking bracket 222. The locking bracket 222 is fixed to the bottom surface of the sealing push plate 221 and slidably connected to the bottom of the sealing cover 200. The sealing push plate 221 is blocked at the top of the second detection hole 210 by translation, and the locking bracket 222 is pushed and translated by the sealing push plate 221 and stopped at the bottom surface of the push block 620. The sealing component 220 integrates a sealing push plate 221 and an L-shaped locking bracket 222. The sealing push plate 221 slides and adheres to the top surface of the sealing cover 200, which can accurately move and block the second detection hole 210, avoiding interference from the external environment to the temperature and humidity sensor 400. The sliding and adhering sealing push plate 221 provides a tight seal, which greatly slows down the aging rate of the temperature and humidity sensor 400 when it is idle, thus extending its service life. The L-shaped locking bracket 222 is fixed to the bottom surface of the sealing push plate 221 and slidably connected to the bottom of the sealing cover 200. It moves synchronously with the sealing push plate 221 and can accurately stop at the bottom surface of the push block 620 to lock the sheath assembly 600.

[0043] In this embodiment, a baffle 630 is sleeved on the outer wall of the push block 620. The baffle 630 slides against the inner wall of the outer shell 100 and closes the opening inside the outer shell 100 for the push block 620 to slide. The outer wall of the push block 620 is fitted with a baffle 630. The baffle 630 slides against the inner wall of the outer shell 100 and seals the sliding opening inside the outer shell 100 to form a sliding seal structure, preventing dust and moisture from entering through the opening. The baffle 630 slides synchronously with the push block 620, providing sliding guidance and limiting for the push block 620, ensuring that the push block 620 rises and falls smoothly along the first slide rod 160, driving the sleeve 610 to move synchronously and smoothly. The sealing and fitting design of the baffle 630 improves the overall protective sealing of the interior of the outer shell 100.

[0044] In this embodiment, the bottom surface of the outer shell 100 is provided with a through hole 190, and multiple through holes 190 are provided corresponding to the first detection hole 110. The gap between the wind speed detection component 500 and the first detection hole 110 is provided. The sleeve 610 slides downward on the outer wall of the outer shell 100 to form a pressure chamber between the bottom end of the outer shell 100 and the inside of the sleeve 610. The pressure chamber is connected to the inside of the outer shell 100 through the through hole 190. Multiple through holes 190 corresponding to the first detection hole 110 are opened on the bottom surface of the outer shell 100. The gap between the wind speed detection component 500 and the first detection hole 110 is set to ensure smooth airflow and improve detection accuracy. When the sleeve 610 slides down, the bottom end of the outer shell 100 and the inside of the sleeve 610 form a pressure chamber. The pressure chamber is connected to the inside of the outer shell 100 through the through holes 190, providing a structural basis for airflow and self-cleaning. The pressure chamber structure provides power for cleaning and protecting the wind speed sensor 510, simplifying the structure and improving ease of use.

[0045] In this embodiment, an isolation cover 180 is fixed to the inner wall of the outer shell 100. The isolation cover 180 is connected through the through hole 190 and the first detection hole 110. A wind speed detection component 500 is connected through one side of the isolation cover 180. The wind speed detection component 500 includes a wind speed sensor 510 that is connected through the interior of the isolation cover 180. One end of the wind speed sensor 510 is fixed with a sloping push plate 520. A second slide rod 530 is provided through the interior of the sloping push plate 520. One end of the second slide rod 530 is connected to the side wall of the isolation cover 180. A second spring 540 is sleeved on the outer wall of the second slide rod 530. One side of the sloping push plate 520 is a sloping push surface, which is composed of an upper vertical surface, a sloping surface and a lower vertical surface. A sloping top block 680 is attached to one side of the sloping push surface of the sloping push plate 520. An isolation cover 180 is fixed to the inner wall of the outer casing 100 and is connected through the through hole 190 and the first detection hole 110. It provides a directional guiding channel for airflow. When the wind speed sensor 510 is housed inside the outer casing 100, the air pressure chamber contracts and discharges the internal air through the isolation cover 180. The air cleans and protects the side wall of the wind speed sensor 510, preventing impurities from being introduced into the wind speed sensor 510 after it is housed inside the outer casing 100, which would then contaminate the electronic components installed inside the outer casing. This helps to improve the reliability of the meteorological instrument.

[0046] In this embodiment, the isolation cover 180 has a funnel-shaped structure that is narrower at the top and wider at the bottom. An arc-shaped air guide plate 181 is fixed to the inner wall of the isolation cover 180 near the first detection hole 110. An air outlet channel is provided between the air guide plate 181 and the inner wall of the isolation cover 180 on the other side. An elastic telescopic rod 511 is connected to one side of the wind speed sensor 510. A wind baffle ring 512 is connected to one end of the elastic telescopic rod 511. The wind baffle ring 512 is fitted between the inner wall of the isolation cover 180 and the arc-shaped inner wall of the air guide plate 181. The inner wall of the wind baffle ring 512 is flush with the inner wall of the wind speed sensor 510. The outer wall gap is set. The first detection hole 110 is fixed with an air guide ring 111. The side of the air guide ring 111 near the inside of the outer shell 100 is a sloping structure. The side of the wind baffle ring is a sloping structure and is fitted with the sloping structure of the air guide ring 111. The elastic telescopic rod 511 is retracted into the inside of the outer shell 100 through the wind speed sensor 510 and moves horizontally, so that the elastic telescopic rod 511 pulls the wind baffle ring 512 to move horizontally, so that the wind baffle ring 512 and the air guide ring 111 are spaced apart and a backflow groove is formed. The backflow groove is used to guide the air into the inside of the end of the wind speed sensor 510. An isolation cover 180 with a funnel-shaped structure that is narrow at the top and wide at the bottom is used. Inside the isolation cover 180, an air guide plate 181 and a wind baffle ring 512 are set to guide airflow. When the air pressure chamber decreases, the air in the air pressure chamber gathers and enters between the outer wall of the wind speed sensor 510 and the inner wall of the wind baffle ring 512, increasing the wind speed of the air passing through the outer wall of the wind speed sensor 510. Then, it is discharged from the first detection hole 110, which increases the air ejection speed. Thus, when the wind speed sensor 510 is stored, the air discharged from inside the isolation cover 180 can quickly spray off the dew adhering to the surface of the wind speed sensor 510 and spray it out through the first detection hole 110. This avoids the dew adhering to the side wall surface of the wind speed sensor 510 being introduced into the housing 100 when the wind speed sensor 510 is retracted into the housing 100, which would cause excessive moisture inside the meteorological instrument. This helps to further improve the reliability of the meteorological instrument. When the wind speed sensor 510 is further retracted into the housing 100, the wind deflector ring 512 and the air guide ring 111 separate and form a backflow groove between them. The backflow groove guides air into the wind speed sensor 510. The accelerated air rapidly cools the metal wire inside the wind speed sensor 510 that measures wind speed, and the internal heat is discharged through the first detection hole 110. Then the sleeve 610 completely seals the first detection hole 110 to prevent the wind speed sensor 510 from retracting into the housing 100. When the meteorological instrument is in the retracted and sealed storage state, the overheated metal wire in the wind speed sensor 510 has an excessive impact on the internal temperature of the meteorological instrument, causing the internal temperature of the meteorological instrument to rise rapidly in a short period of time. During the subsequent carrying of the meteorological instrument, because it is placed in a pocket or storage bag, the internal heat is even more difficult to dissipate, which may affect the service life of the electronic components installed inside the meteorological instrument due to high temperature, or even cause damage. This ensures the reliable and stable operation of the meteorological instrument. Finally, after the wind speed sensor 510 is completely stored, not only does the sleeve 610 seal the first detection hole 110, but the wind deflector ring 512 and the wind guide plate 181 are also sealed inside the isolation cover 180, further improving the airtightness between the sleeve 610 and the bottom surface of the outer shell 100.

[0047] In this embodiment, a waterproof and breathable valve 700 is internally connected to the sealing cover 200. The bottom end of the waterproof and breathable valve 700 is internally connected to the bottom end of the outer shell 100, and the bottom end of the waterproof and breathable valve 700 is internally connected to the air pressure chamber. A sealing ring 120 is fixed to the bottom surface of the outer shell 100 and fits against the inner wall of the sleeve 610. The waterproof and breathable valve 700 is internally connected to the sealing cover 200, and its bottom end is internally connected to the air pressure chamber, realizing the air pressure balance between the inside of the air pressure chamber and the outside. It can continue to discharge the air inside the air pressure chamber after the first detection hole 110 is closed, ensuring that the sleeve 610 slides smoothly without jamming. The waterproof and breathable valve 700 allows air to pass through and prevents moisture from entering, improving the waterproof performance of the equipment. The sealing ring 120 is fixed to the bottom surface of the outer shell 100 and fits against the inner wall of the sleeve 610, ensuring the airtightness of the air pressure chamber and providing a reliable air pressure basis for the self-cleaning function.

[0048] In this embodiment, the sheath assembly 600 further includes a sealing ring 640 fixed to the bottom surface of the inner sleeve 610. The sealing ring 640 is disposed at the bottom of multiple through holes 190 and is used to fit and seal the bottom surface of the through holes 190. A rubber pad 650 is fixed inside the sealing ring 640. The sealing ring 640 of the sheath assembly 600 is fixed to the bottom surface of the inner sleeve 610 and is disposed corresponding to the through holes 190. When stored, it fits and seals the bottom surface of the through holes 190 to prevent moisture and dust from entering. When not in use, the internal components are free from contamination. The rubber pad 650 fixed inside the sealing ring 640 can be used to cushion the bottom surface of the outer shell 100 by fitting the rubber pad 650 against it, preventing the outer shell 100 and the inside of the sleeve 610 from colliding and ensuring the safety of the internal structure.

[0049] In this embodiment, the sheath assembly 600 further includes a rubber ring 660, which is fitted onto the outer wall of the sleeve 610. Multiple rubber rings 660 are provided. Touching the rubber ring with a finger prevents the hand temperature from affecting the sensor inside the housing, thus providing heat insulation and anti-slip properties, ensuring the safety of the handheld meteorological instrument.

[0050] Example 2: This embodiment of the invention provides a method for using a portable weather instrument, applying the portable weather instrument described in Example 1. The method includes the following steps: S1, Push to unlock; The sealing cover 200 is pushed to slide the sealing push plate 221, which opens the second detection hole 210 and causes the locking bracket 222 to separate from the push block 620, releasing the stop on the push block 620; the compressed first spring 170 pushes the push block 620 to slide downward along the first slide rod 160, and the push block 620 causes the baffle 630 to slide down along the inner wall of the outer shell 100 and pushes the sleeve 610 down along the outer wall of the outer shell 100, so that the sealing ring 640 and the rubber gasket 650 are separated from the outer shell 100. The interior of the outer shell 100 is connected to the air pressure chamber through the through hole 190. The volume of the air pressure chamber increases, creating a negative pressure inside the outer shell 100. Air enters the outer shell 100 and the air pressure chamber through the waterproof vent valve 700; at the same time, the sleeve 610 opens the first detection hole 110 and the charging communication interface 140, and the external air Air enters the air pressure chamber through the first detection hole 110. It can be connected to an external charging or communication device through the charging communication interface 140, and the charging status can be observed through the charging indicator light 130. The inclined top block 680 pushes the inclined push plate 520 downward to move towards the isolation cover 180. The wind speed sensor 510 extends out of the outer shell 100 through the first detection hole 110. The exemplary wind speed sensor 510 adopts a high-precision omnidirectional wind speed and temperature sensor of model JT1411, with a wind temperature range of -25-70℃ and a wind speed resolution of 0.01m / s. As the wind speed sensor 510 extends, the elastic telescopic rod 511 pushes the wind baffle ring 512 to fit with the wind guide ring 111. The wind baffle ring 512 opens the channel between the wind guide plate 181 and the inner wall of the isolation cover 180 and compresses the elastic telescopic rod 511. S2, Start detection; Pressing button 300 activates circuit board 900. Circuit board 900 is electrically connected to button 300, temperature and humidity sensor 400, wind speed sensor 510, and charging communication interface 140. Holding sleeve 610, the entire instrument is raised above the head. Fingers are placed against the rubber ring 660 around sleeve 610 to improve hand stability, prevent slippage, and isolate hand temperature from interference with detection. Temperature and humidity sensor 400 detects external temperature and humidity through second detection hole 210. Multiple wind speed sensors 510 detect external wind speed through first detection holes 110 extending in multiple directions. Detection data is stored in storage elements of circuit board 900. During detection, if moisture or impurities adhere to the inner wall of first detection hole 110, pressing the outer shell 100 and sleeve 610 reduces the volume of the air pressure chamber. Sealing ring 120 adheres to the inner wall of sleeve 610 to keep the air pressure chamber sealed. Air in the air pressure chamber is ejected through first detection hole 110 to remove moisture or impurities and ensure detection accuracy. S3, Pressure and Blockade; Pressing the outer shell 100 causes it to retract into the sleeve 610. The pusher 620 slides upward along the first slide bar 160 and compresses the first spring 170, reducing the volume of the air pressure chamber. The air inside the chamber is first ejected through the first detection hole 110 to clean the first detection hole 110 again, and to cool the wind speed sensor 510 and remove any attached dew. Pressing continues until the sleeve 610 seals the first detection hole 110 and the charging communication interface 140. The remaining air inside the chamber is discharged through the waterproof vent valve 700 until the sealing ring 640 fits against the bottom surface of the sealing through hole 190. The pusher plate 221 is pushed to seal the top surface of the second detection hole 210, and the locking bracket 222 moves to stop the pusher 620, completing the instrument storage and protection. Collision protection is achieved through the rubber ring 660 around the sleeve 610, ensuring the safety of the instrument.
