Description of the invention (1) The present invention relates to a non-destructive quality detector for vegetables, fruits and eggs, mainly because the moving parts and the cover inside the empty tube of the towel are provided with magnetic objects of the same polarity when the detection head is struck. When the vegetable and fruit skins and egg shells, the moving parts will be retracted into the hollow tube, and the magnetic material will create a repulsive buffering effect to avoid excessive reaction forces from damaging the vegetable and fruit skins and egg shells. At the same time, a hemisphere is equipped with a microphone It can directly receive the reflected wave generated when the vegetable and fruit skins and egg shells are struck, that is, it will be displayed on the oscilloscope to make a simple and clear judgment _ pulse _, and it will not be affected by resonance noise. ≪ Background of the Invention > According to the above, it was previously approved by the Bureau of Announcement, announcement number: No. 3397976 "detector for egg testing, egg testing device, testing equipment and testing for egg testing The "pattern of eggs" invention patent case is learned based on the summary of the patent: 1. A detector (30) used in an egg testing device, the detector includes a bottom end (32) with a ring magnet (34) for detection Tube (31). A spherical activation member (50) is a ring magnet (34) held magnetically inside the detection tube. The detector ⑽ can be moved axially inside the metal pipe ⑴) and two bobbins (14) are sleeved around the metal pipe ⑴). The detector (30) is held in its rest position by the magnetic attraction between the metal tube (11) and the ring magnet (34). The detection pulse sent to the bobbin 引导 is guided to its operating position. The pulse is generated by a control device (200). The control device considers the diameter of the egg ⑶ to be measured and the diameter of the conveyor (110). This pulse is emitted by a factor of the conveying speed (V). However, the invention patent of the above-mentioned "Lin test egg detector, egg test device body used to test 591223 Λ7 V. Invention description (2) test equipment and method of egg test", in actual operation and application, still at least There are the following problems and shortcomings to be solved: '1. Inside the metal tube (11), the air column (20) above the activation member (50) causes sound vibration, and these sound vibrations will be generated in the air column ( 20) spread upward, and reached the microphone (40) located at the top of the air column (20), because the signal '40' received by the microphone (40) was received indirectly through the vibration of the air column (20) Will be disturbed by external noise, such as: relays, and because the air column (20) will generate resonance noise, the signal pattern emitted by the microphone (40) during the test of a good egg, the signal Pattern discrimination will also be more complicated 'and only one detection point can be tapped at a time. 2. The detector (30) is a current pulse (or voltage pulse) of a first electrode and a second electrode, so that the magnetic field generated by the bobbin (14) is applied to the ring magnet (34)-a repulsive force and attraction The force allows the detector (30) to be moved. Because the bobbin (14) is in the humid climate of Taiwan, it will easily affect the normal operation of the coil and IC board, resulting in the graphic signal reception of the microphone (40). bad. In view of this, the inventor's popularity is the spirit of actively investing in research and development and innovation and improvement, and finally completed the present invention, which is to provide a non-destructive quality detector for fruits and vegetables and eggs. < Specific embodiments > In order to make it easy for those who are familiar with this technology to understand the construction content of the present invention and the functional benefits that can be achieved, a specific embodiment will be listed, and it will be described in detail with the drawings as follows : A non-destructive quality tester for fruits, vegetables and eggs, please refer to the first paper size applicable to China National Standard (CNS) A4 (210 X 297 male: g). ≫ Printed by the Bureau of Consumer Cooperation 37 37 Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 591223 V.
