Abstract
Description
Technical Field
[0001] This utility model mainly relates to the technical field of temperature and humidity sensors, specifically an indoor temperature and humidity acquisition device. Background Technology
[0002] An indoor temperature and humidity sensor is an instrument used to measure the temperature and humidity of an indoor environment. It can measure the indoor temperature and humidity in real time and accurately, and output the measurement results in the form of digital or analog signals. It is usually equipped with a display screen, which can directly display the current temperature and humidity values, allowing users to intuitively understand the indoor environmental conditions. Some temperature and humidity sensors have data storage functions, which can record temperature and humidity changes over a period of time for subsequent analysis. At the same time, it can also transmit data to other devices, such as computers and mobile phones, via wired or wireless communication to achieve remote monitoring and control.
[0003] After a period of use, dust will accumulate on the probe of a temperature and humidity sensor. This dust forms a heat-insulating layer on the probe surface, hindering heat transfer and preventing the probe from accurately sensing the true temperature of the surrounding environment. Under normal circumstances, the temperature sensor can quickly respond to changes in ambient temperature, but the dust on the probe surface slows down the transfer of heat to the sensitive elements inside the probe. The dust may also attract moisture, corrosive gases, and other substances from the air. Long-term accumulation of these substances on the probe surface may corrode or oxidize the probe material, shortening its lifespan. Currently, there are two main probe designs for indoor temperature and humidity sensors: one with the probe exposed and the other with the probe located inside the sensor housing. For exposed probes, users can manually wipe off the dust. For internal probes, the sensor housing must be removed each time it is wiped, which is inconvenient and presents a technical drawback. Utility Model Content
[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, this utility model provides an indoor temperature and humidity acquisition device to solve the technical problem mentioned in the background that some probes in current indoor temperature and humidity sensors are built into the sensor housing, making it inconvenient for users to wipe them regularly.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] An indoor temperature and humidity acquisition device includes a temperature and humidity acquisition mechanism, which comprises a first outer shell and a second outer shell. The first outer shell contains a detection chamber and a nozzle. The nozzle has a conical structure, and its narrow end communicates with the detection chamber. The second outer shell contains two slots symmetrically distributed, on which a circuit board is attached. A temperature and humidity sensitive element is mounted on the circuit board and located within the detection chamber to detect the external temperature and humidity. A partition is provided on one side of the detection chamber, and a sealing strip is provided at a notch in the partition. The sealing strip presses against the circuit board, separating the detection chamber from the space occupied by the slots.
[0007] Furthermore, a sealing cap is provided on the side of the nozzle facing outwards.
[0008] Furthermore, two folded edges are provided on one side of the detection cavity, and a perforated protective sheet is provided between the two folded edges.
[0009] Furthermore, the circuit board is also equipped with signal processing components, power management components, a battery module, and a microprocessor module.
[0010] Furthermore, a positioning frame is provided on the first housing, and a display is provided inside the positioning frame. The display is electrically connected to the microprocessor module.
[0011] Furthermore, a hanging ring is provided at the upper edge of the outer wall of the first outer shell.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model, through its first outer shell, detection chamber, partition, sealing strip, air outlet, second outer shell, circuit board, temperature and humidity sensitive element, cover, and perforated protective sheet, enables users to maintain indoor temperature and humidity sensors without disassembling the sensor's outer shell. Simply remove the cover, blow air into the air outlet, and the dust on the temperature and humidity sensitive element inside the sensor will be blown out from the perforated protective sheet side, achieving the purpose of cleaning the dust. It is very convenient and quick, effectively solving the shortcomings of current technology. Moreover, the structure is simple, easy to assemble, and low in cost, and has certain practical value.

[0023] Please refer to the appendix carefully. Figure 1-4An indoor temperature and humidity acquisition device includes a temperature and humidity acquisition mechanism 1, which includes a first outer shell 11 and a second outer shell 12. The first outer shell 11 has a detection chamber 111 and a nozzle 114. The nozzle 114 has a conical structure, and its narrow end is connected to the detection chamber 111. The second outer shell 12 has two slots 121, which are symmetrically distributed. A circuit board 13 is snapped onto the two slots 121. A temperature and humidity sensing element 131 is provided on the circuit board 13. The temperature and humidity sensing element 131 is located in the detection chamber 111 and detects the external temperature and humidity. A partition 112 is provided on one side of the detection chamber 111. A sealing strip 113 is provided at the notch on the partition 112.

[0025] The specific operation is as follows: When the user needs to maintain the indoor temperature and humidity sensor, first remove the cover 14, and then blow air into the nozzle 114. Since the nozzle 114 is a conical structure, according to the Venturi effect, it accelerates the gas flow in the detection chamber 111, and carries away the floating dust on the temperature and humidity sensitive element 131 in the detection chamber 111, so that the floating dust is blown out from the round hole on the perforated protective plate 15, thereby achieving the purpose of cleaning the floating dust.
