Description

Technical Field

[0001] The utility model relates to the field of RFID tags, and more specifically, to a liquid-resistant RFID tag. Background Art

[0002] RFID tags are widely used in various fields such as access control, aviation package identification, document tracking management, package tracking and identification, logistics management, product anti-counterfeiting, ticket management, automobile chip anti-theft devices, parking lot management, production automation, and retail management. When the current RFID tags are installed on goods with liquids, the liquid in the bottle will easily affect the conduction of the chip when it flows onto the tag, which makes the tag prone to errors when reading. In addition, the chips in most RFID tags are not easy to recycle, which reduces the applicability of RFID tags.

[0003] Chinese patent application number: CN202222119925.0, provides an RFID tag that is resistant to liquid interference. The solution is provided by setting a protective shell, a first movable plate, a card column, a spring and a card slot. When the operator needs to replace the chip in the tag, he can manually press the first movable plate and the second movable plate to move the first movable plate and the second movable plate inward, and then the card column on the left side of the first movable plate will be separated from the card slot, and then the protective shell and the tag will be separated, and then the chip in the tag will be replaced. When the RFID tag is installed on a product with liquid, the liquid in the bottle will flow to the top of the protective shell, so that the protective shell can prevent the liquid from interfering with the chip conduction, thereby avoiding the phenomenon of errors in reading the tag.

[0004] However, during use, external water vapor and liquid are easily attached to the surface of the tag. In order to ensure the use of the tag, the liquid and water vapor on the tag need to be cleaned in time, which requires manpower and time. Therefore, a liquid-resistant RFID tag is proposed to address the above problem. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a liquid-resistant RFID tag. A water guide groove is opened on the cover of the top cover. The water guide groove cooperates with water absorbent beads so that when external liquid is spilled on the top cover, the liquid can be absorbed and drained, thereby preventing the liquid from adhering to the top cover. There is no need to manually clean the liquid, thereby reducing labor.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A liquid-resistant RFID tag comprises a bottom cover, a top cover is installed at the top of the bottom cover, the top cover has the same structure as the bottom cover, the top cover and the bottom cover are symmetrically distributed, a sealing strip is installed at the bottom end of the top cover and at the top end of the bottom cover, an RFID tag chip is installed at the bottom end of the top cover and at the top end of the bottom cover, the RFID tag chip is located on the inner side of the sealing strip, the RFID tag chip is matched with the sealing strip, and a connecting buckle is fixedly connected to the front end of the bottom cover; the top cover comprises a lid, a water guide groove is opened at the top end of the lid, a plurality of water absorbent beads arranged at equal distances are installed at the top end of the water guide groove and at the top end of the lid, and the water absorbent beads are matched with the water guide groove;

[0008] The top cover and the bottom cover cooperate to wrap the RFID tag chip for protection, prevent external water vapor from adhering to the RFID tag chip, and achieve the purpose of liquid resistance of the RFID tag chip. At the same time, the sealing strip increases the sealing performance when the top cover and the bottom cover are connected, further improving the liquid resistance of the top cover and the bottom cover to the RFID tag chip. In addition, a water guide groove is provided on the cover of the top cover. The water guide groove cooperates with the water absorbent beads so that when external liquid is spilled on the top cover, the liquid can be absorbed and drained, preventing the liquid from adhering to the top cover. There is no need to manually clean the liquid, thus reducing labor.

[0009] Reference Figure 4 As shown, the absorbent bead includes a half bead, and absorbent cotton is installed inside the half bead. The bottom end of the absorbent cotton is fixedly connected with a water guide bar, and the water guide bar passes through the bottom end of the half bead and extends to the inside of the water guide groove.

[0010] The interior of the half bead is a cavity, and the cavity is adapted to the water-absorbing cotton.

[0011] The outer wall of the half bead is provided with a plurality of through holes arranged at equal distances, the through holes are connected with the cavity, and the through holes are in contact with the absorbent cotton;

[0012] The position of the absorbent cotton is limited by the half bead. When external liquid contacts it, the absorbent cotton absorbs the liquid through the through hole and guides the liquid into the water guide groove through the water guide strip. The water guide groove further drains the liquid so that the liquid drips along the water guide groove to prevent liquid adhesion and increase the liquid resistance of the top cover and the bottom cover to the RFID tag chip.

[0013] Reference Figure 2 As shown, a card slot is provided at the top of the bottom cover, the card slot is matched with the sealing strip, and the card slot and the sealing strip are detachably connected.

[0015] In summary, the utility model has the following beneficial effects:

[0016] (1) This solution uses a top cover and a bottom cover to wrap the RFID tag chip for protection, preventing external water vapor from adhering to the RFID tag chip, thereby achieving the purpose of liquid resistance of the RFID tag chip. At the same time, the sealing strip increases the sealing performance when the top cover and the bottom cover are connected, further improving the liquid resistance of the top cover and the bottom cover to the RFID tag chip. In addition, a water guide groove is provided on the cover of the top cover. The water guide groove and the water absorbent beads can absorb and drain the external liquid when it falls on the top cover, thereby preventing the liquid from adhering to the top cover. There is no need to manually clean the liquid, thereby reducing labor.

[0017] (2) This solution uses a half bead to limit the position of the absorbent cotton. When external liquid contacts it, the absorbent cotton absorbs the liquid through the through hole and guides the liquid into the water guide groove through the water guide strip. The water guide groove further drains the liquid so that the liquid drips along the water guide groove, preventing liquid adhesion and increasing the liquid resistance of the top cover and the bottom cover to the RFID tag chip.
