1. Field of Invention
The present invention relates to a dustproof and waterproof performance detection device, and more particularly a detection device capable of observing a detection process of an object with naked eyes.
2. Related Art
Electronic products, such as personal digital assistants, GPS navigators, cell phones, and outdoor antennae will be operated at a harsh environment or an unstable outdoor environment. In these environments, dust and water always damage the electronic devices. Accordingly, the electronic devices must have good dustproof and waterproof effects, such that dust and water will not invade into the electronic devices to damage the electronic parts when being used in these environments.
Therefore, in product design, it is important to ensure the safety of the parts. However, for machine design or quality management staff, it definitely costs a lot of time and energy to thoroughly validate the safety of each part, while safety specifications are effective tools for measuring the safety of parts. For example, international designations (IEC specifications) established by International Electrotechnical Commission and European Norm specifications (EN specifications) established by European Committee for Standardization (CEN) and European Committee for Electrotechnical Standardization (CENELEC) set forth an IP grade system, which classifies products according to dustproof and waterproof performance of protection constitutions of the machines. The IP grade is composed of two numbers indicating properties, and the larger the number is, the higher the protection grade is. The first number refers to a protection grade of preventing from be contacted and invaded by human body or solid foreign matter, and is indicated by 0 to 6. The second number refers to a waterproof grade, and is indicated by 0 to 8. Taking IP67 as an example, 6 refers to a complete dustproof constitution, and the corresponding test condition must have no dust invading, and 7 refers to being capable of applied under water conditionally, and the corresponding test condition is being immersed under water at a depth of 1 meter for 30 minutes, and the product should not malfunction.
Generally speaking, when manufactures send the products to validaters, the validaters will perform the dustproof and waterproof performance detection according to the IEC specifications and EN specifications. However, the manufactures merely know whether the product pass through the detection, without further knowing the conditions during the detection or in the detection state of the failed products. More specifically, for example, the condition of waterproof test of IP67 is to immerse under water at a depth of 1 meter for 30 minutes. The product may fail the test at a depth of less than 1 meter under water or at a time for less than 30 minutes, but the manufacturers cannot obtain the conditions of detection failure of the product. Therefore, the manufacturers cannot further improve the product according to the information, and cannot pass through the validation to obtain corresponding safety signs indicating qualification.
As manufacturers cannot obtain the conditions of detection failure of the product in the prior art, they cannot make further development and improvements according to the information. In view of this, the present invention provides a dustproof and waterproof performance detection device, in which the detection process of an object can be observed by naked eyes, so as to obtain the conditions of the detection failure of the product
The dustproof and waterproof performance detection device of the present invention is used to detect dustproof and waterproof performance of an object. The detection device includes a box, a carrier, and a gauge. The box has at least one side being observable by naked eyes and carries a solution. The carrier is movably disposed in the box and carries the object to move gradually in a depth direction of the box to a detection position according to detection requirements. The gauge extends along the depth direction of the box and has a plurality of scales distributed at equal intervals.
According to the dustproof and waterproof performance detection device of the present invention, the box is made of a transparent material, such as tempered glass, such that the tester can observe whether there are bubbles generated by the object with naked eyes during the detection, so as to analyze or adjust the detection state. Furthermore, the gauge of the present invention has scales for defining the water depth, such that the tester can use the carrier to carry the object and gradually move to the detection position in the depth direction of the box, and compare with the scales of the gauge. When the object is invaded by the solution at the detection position, the tester can record the position and obtain the conditions of detection failure of the product, so as to make further developments and improvements on the product according to the information. Therefore, compared with the convention technology that merely capable of indirectly obtaining the detection results, the present invention makes the tester to control the whole detection process and obtain more direct and detailed detection information according to detection requirements.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus are not limitative of the present invention, and wherein:
In order to make the object, structure, features, and functions of the present invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.
The dustproof and waterproof performance detection device of the present invention is used to detect dustproof and waterproof performance of an object. The object includes, but not limited to, an electronic product, such as an outdoor antenna, a personal digital assistant, a GPS navigator and a cell phone. Moreover, the technology of the present invention is also applicable for products satisfying the dustproof and waterproof performance grade IP67. In embodiments of the present invention, an outdoor antenna is used as application embodiment.
Referring to
The carrier 330 is movably disposed in the box 320. The carrier 330 includes a movable rod 331 and two fixed rods 332. The two fixed rods 332 is disposed at one end of the movable rod 331 in a radial direction of the movable rod 331, and the two fixed rods 332 are crossed with each other. The movable rod 331 penetrates the through hole of the support block 323, extends into the accommodating chamber 321 of the box 320, and moves in a depth direction of the box 320. The two fixed rods 332 are used to dispose an outdoor antenna 500. As the outdoor antenna 500 is required to be detected under water at a depth of 1 meter, the overall length of the carrier 330 must be greater than 1 meter for performing the detection.
The gauge 340 is disposed on the box 320, which can be realized by being adhered on the box 320 or directly built in the box 320, and is located on the side of the accommodating chamber 321 that is observable by naked eyes. Furthermore, the gauge 340 extends in the depth direction of the box 320, with a length greater than or equal to 1 meter, and has a plurality of scales 341 distributed at equal intervals. Herein, the unit of the interval of the gauge 340 is in centimeter, and the interval between the scales 341 is, for example, but not limited to, 10 centimeters, thereby forming eleven markers of 0 to 100.
Please refer to
If the outdoor antenna 500 can still bear the water pressure, the tester can move the movable rod 331 continuously, and compare with the scales 341 of the gauge 340, such that the outdoor antenna 500 reaches the detection position of 100 centimeters deep. At this time, the water pressure is 0.1 kg/cm2. The tester begins to time for 30 minutes, if the outdoor antenna 500 can be immersed under water at a depth of 100 centimeters for 30 minutes, the initial detection process is completed.
