Description

Technical Field

[0001] This utility model relates to a wood moisture testing device, belonging to the field of wood measurement technology. Background Technology

[0002] Wood moisture testers have a wide range of applications in the measurement field, covering large, medium, and small manufacturing industries. This type of wood moisture tester contacts the object being tested via conductive adhesive tape. However, deformation caused by factors such as molding of the housing, wrinkles in the conductive adhesive tape, installation-related deformation, environmental temperature-induced deformation of the tester, unevenness of the object's surface, bending deformation of the object, and environmental temperature-induced deformation can prevent the wood moisture tester from making a tight fit with the object, resulting in inconsistent measurement data.

[0003] Existing technology, such as the utility model patent with patent number "CN219997088U", discloses a wood moisture meter for wood testing, including a protective shell, the inner cavity of which is fixedly connected to the instrument body. This utility model uses a spring to keep the detection needle within the inner cavity of the protective shell, thus protecting the needle. When needed, the operator overlaps the elastic rubber pad with the surface of the wood to be tested. By moving downwards, the protective shell moves downwards under the action of the guide rod and spring, causing the detection needle to move into the inner cavity of the wood. Simultaneously, the elastic rubber pad and spring prevent the protective shell from bumping against the surface of the wood. After testing, the spring moves the protective shell upwards, returning the detection needle to the inner cavity. A soft brush cleans the outer wall of the needle as it returns to the inner cavity.

[0004] However, the above technical solution requires two probes to contact the test object to complete the moisture test when measuring the moisture content of wood. However, since the probes are fixed, when facing a test object with an uneven or bent surface, it is impossible to make both probes contact the test object at the same time, and test data cannot be obtained.
