Description

Technical Field

[0001] This utility model relates to the technical field of environmental variable measurement devices, and in particular to a wireless temperature and humidity information acquisition instrument that is resistant to water vapor erosion. Background Technology

[0002] A wireless temperature and humidity data acquisition device is a device that collects and records temperature and humidity data wirelessly. It can collect and record temperature and humidity data within a monitored area and transmit it wirelessly to a data processing terminal. This assists management in statistically analyzing and controlling the temperature and humidity environmental indices of the area, and it can be widely used in various industries such as planting, animal husbandry, and transportation. Because wireless temperature and humidity data acquisition devices operate in temperature and humidity environments, they contain numerous electronic components such as a CPU, large-scale integrated circuits, FLASH storage, intelligent signal conditioning, a SmartBus bus, and a high-resolution graphic LCD display. Therefore, preventing moisture from corroding the internal casing is particularly important. Some wireless temperature and humidity data acquisition devices on the market apply sealant to the seams of their casings to address the moisture problem. However, in actual use, it has been found that while sealant can improve the initial moisture resistance, it significantly hinders later disassembly and maintenance. Each repair requires reapplying sealant, increasing the difficulty and cost of equipment maintenance and reducing its reusability. Utility Model Content

[0025] A waterproof temperature and humidity sensor was also designed, including the aforementioned waterproof temperature and humidity sensor housing.

[0026] The above embodiments illustrate three examples of implementing the aforementioned technical solutions. The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of this application. The appearance of this phrase in various locations within the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0027] Embodiment 1 discloses a waterproof temperature and humidity acquisition instrument housing, including a housing body 1. The housing body 1 has a component compartment 11 inside, which is used to fix components such as a CPU, large-scale integrated circuits, FLASH storage, signal intelligent conditioning, and SmartBus bus. The side of the housing body 1 has a connector hole 12 for exposing a connector for electrical signal connection to external units. The housing body 1 includes a front shell 13 and a rear shell 14, which can be injection molded in one piece.

It is made of rubber, silicone, or silicone rubber. The outer side of the integrated sealing ring 2 is integrally provided with a rubber gasket 21 for use with the blind hole 132 of the assembly thread, and an integrally provided rubber cap 22 for use with the connector hole 12. The rubber cap 22 is designed to conform to the shape of the connector hole 12. When the connector hole 12 is not in use, the rubber cap 22 is used to block the connector hole 12 to prevent moisture from entering from the connector hole 12. The rear shell 14 is provided with a sealing boss for use with the sealing groove 131, and an assembly through hole post 141 for use with the blind hole 132 of the assembly thread.

In this embodiment, the cover 3 is provided with a through hole, and the rear shell 14 is provided with a threaded hole. After the cover 3 covers the battery compartment 142, the cover 3 and the threaded hole are fastened by fastening screws and the sealing gasket to achieve the airtight effect of the battery compartment.

[0032] like Figures 1 to 5 As shown, Embodiment 3 discloses a waterproof temperature and humidity acquisition device housing. The difference between this embodiment and Embodiment 2 is that the battery compartment 142 has a hinge slot 144 on its outer side, as shown.
