A structure of an electronic tag component 6 mounted on a diaper 2 will be exemplarily described below in conjunction with FIGS. 2 to 4.

Refer to FIG. 2 which is a schematic structural diagram of an electronic tag component 6 which can be mounted on a diaper 2 shown in FIG. 1 in an embodiment of the present disclosure.

The electronic tag component 6 includes a first radio frequency electronic tag for detecting a first radio frequency signal representing that the diaper 2 is located in a perceptible area and a second radio frequency electronic tag for detecting a second radio frequency signal representing the existence of a liquid (such as urine), the first radio frequency electronic tag is a liquid-insensitive electronic tag, and the second radio frequency electronic tag is a liquid-sensitive electronic tag.

It should be noted that the liquid-sensitive electronic tag refers to an electronic tag sending a radio frequency signal of which an intensity value is linearly attenuated relative to a liquid humidity value in a humid working environment, the greater the humidity value is, the smaller the intensity value of the sent radio frequency signal is, and when the humidity value of the working environment tends to 100%, the intensity value of the sent radio frequency signal tends to 0; and the liquid-insensitive electronic tag refers to an electronic tag sending a radio frequency signal of which an intensity value is not attenuated or weakly attenuated relative to a liquid humidity value in a humid working environment, for example, for an ultrahigh-frequency (such as 860-960 MHZ) radio frequency electronic tag based on a slot antenna, when the humidity value of the working environment changes within an interval [0%, 100%], a variation amplitude of the intensity value of the sent radio frequency signal is smaller than a preset value (such as 5 dB).

In the present embodiment, the first radio frequency electronic tag is a radio frequency electronic tag based on a slot antenna (refer to FIG. 3), and the second radio frequency electronic tag is a radio frequency electronic tag based on an electric small loop antenna and half-wave dipole antennae (refer to FIG. 4). The first radio frequency electronic tag includes a first conductive substrate, and the first conductive substrate includes a first substrate segment L1, a second substrate segment L2, and a transition substrate segment L0 electrically connected to the first substrate segment L1 and the second substrate segment L2; the first substrate segment L1 is provided with a linear slot 60 and a first tag chip 61 disposed on one side of the slot 60; the first substrate segment L1 and the second substrate segment L2 are horizontally misaligned in a length direction, and the second substrate segment L2 is located on an upper side of the first substrate segment L1 in a width direction (the first substrate segment L1, the transition substrate segment L0, the second substrate segment L2, the slot 60 and the first tag chip 61 form a radio frequency signal slot antenna with a special shape). The second radio frequency electronic tag includes a first half-wave dipole antenna K1, a second half-wave dipole antenna K2, and a transition antenna segment K0 electrically connected to the first half-wave dipole antenna K1 and the second half-wave dipole antenna K2, the transition antenna segment K0 is provided with an electric small loop antenna 63, the electric small loop antenna 63 is provided with a second tag chip 62, and the first half-wave dipole antenna K1, the second half-wave dipole antenna K2 and the transition antenna segment K0 are located in the same straight line in the length direction; and the second substrate segment L2 is located on an upper side of the first half-wave dipole antenna K1, the second substrate segment L2 and the first half-wave dipole antenna K1 are parallel in the length direction, and the first substrate segment L1 and the first half-wave dipole antenna K1 are located in the same straight line in the length direction. The above-mentioned shape and structure have the advantages that: the difficulty in batch manufacture is lowered, the manufacturing efficiency is increased, the physical resistance of the electronic tag component 6 to wrinkles is effectively improved, it is ensured that the single tag has a sufficient antenna area range to ensure antenna efficiency, at the same time, a range of a longitudinal area, occupied by the electronic tag component 6, of the diaper 2, is reduced, centralized detection of signals on key parts (the electronic tag component 6 is usually disposed on a geometric center position, corresponding to a water absorption layer, of the diaper 2) is ensured, shielding influences of a human body on a radio frequency signal in the case that the diaper 2 is used in different postures are reduced, in addition, the usage amount of substrate consumables for the electronic tag can be further reduced.

Preferably, a misalignment distance between the second substrate segment L2 and the first substrate segment L1 which are horizontally misaligned in the length direction is greater than the maximum width of the first half-wave dipole antenna K1 in the width direction (which can reduce mutual interference among signals while ensuring that a sufficient space is vacated at the lower side of the second substrate segment L2 to accommodate the first half-wave dipole antenna K1), and is smaller than two times of the maximum width of the first substrate segment L1 in the width direction, or smaller than two times of the maximum width of the first half-wave dipole antenna in the width direction, or smaller than two times of a larger width value between the maximum width of the first substrate segment L1 in the width direction and the maximum width of the first half-wave dipole antenna in the width direction (which can ensure a moderate spacing between the second substrate segment L2 and the first half-wave dipole antenna K1 in the width direction, further improve the physical resistance of the tag component to the wrinkles, further lower the difficulty in batch manufacture, and further reduce the usage amount of substrate consumables for the electronic tag).

In the present embodiment, the above-mentioned shape and structure of the electronic tag component 6 bring the technical effects: it can be ensured that the second substrate segment L2 and the first half-wave dipole antenna K1 are parallel in the length direction, it can be ensured that a sufficient space is vacated at the lower side of the second substrate segment L2 to accommodate the first half-wave dipole antenna K1, it can be ensured that the first substrate segment L1 and the first half-wave dipole antenna K1 are located in the same straight line in the length direction, and signal interference between the first radio frequency electronic tag and the second radio frequency electronic tag is effectively reduced; and resistance to signal interference can be achieved, at the same time, a moderate spacing between the second substrate segment L2 and the first half-wave dipole antenna K1 in the width direction can be ensured, the difficulty in batch manufacture can be lowered, the manufacturing efficiency can be increased, length and width spaces of the diaper 2 occupied by the electronic tag component 6 can be effectively reduced, the physical resistance of the electronic tag component 6 to the wrinkles can be improved, and an effective balance is formed between the signal interference resistance and the physical resistance to the wrinkles, so that the electronic tag component 6 is applicable to an application scenario of liquid anomaly analysis and prewarning for the diaper 2 based on various radio frequency signals.
