Description

Fingerprint reader combined with sterilization function

technical field

The utility model relates to a fingerprint recognizer, in particular to a fingerprint recognizer combined with a sterilization function.

Background technique

Generally, the fingerprint reader is provided with a fingerprint sensing area for the user's finger to touch, and it is judged whether it is a correct fingerprint through optical analysis.

Since a fingerprint reader will be used by multiple people, and the users must touch the fingerprint sensing area, if one of them has infectious germs on their hands, they may leave the germs on it when they touch the fingerprint sensing area, and the others will When you touch the fingerprint sensing area again, you will be exposed to germs, which may cause the risk of infection with infectious diseases.

In order to prevent the fingerprint reader from becoming a transmission medium of germs, there is a demand for a fingerprint reader that can be automatically sterilized after each person uses it.

Contents of the invention

The purpose of the utility model is to provide a fingerprint recognition device which can automatically sterilize after finger touch and has a sterilizing function.

The utility model combines a fingerprint recognition device with a sterilization function, comprising a casing, a fingerprint sensing module, a sterilization light source and a control module. The fingerprint sensing module is arranged on the casing and has a finger contact area exposed on the surface of the casing. The sterilizing light source is arranged on the casing, and includes a light emitting element and a control circuit, the light emitting element can emit ultraviolet light to irradiate the finger contact area, the control circuit is electrically connected with the light emitting element, and controls the opening and closing of the light emitting element . The control module is electrically connected with the fingerprint sensing module and the control circuit of the sterilizing light source, judges the signal of the fingerprint sensing module sensing finger contact, and sends an instruction to the control circuit to turn on the light emitting element, so that the light emitting element illuminates the finger contact area a predetermined time.

Preferably, the light emitting element is a light emitting diode.

Preferably, the fingerprint reader further includes a fingerprint data storage unit electrically connected to the control module.

Preferably, the fingerprint reader further includes a display device and an input device arranged on the casing and electrically connected to the control module.

The beneficial effect of the utility model lies in: the sterilizing light source automatically irradiates the finger contact area with ultraviolet light for a predetermined time after the finger touches, and the germs are eliminated, so as to prevent the fingerprint reader from becoming a medium for spreading germs and ensure the fingerprint reader. health and safety.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Referring to Fig. 1 and Fig. 2, a preferred embodiment of the fingerprint reader combined with sterilizing function of the present invention includes a casing 1, a fingerprint sensing module 2, a sterilizing light source 3, a control module 4, and a fingerprint data storage unit 5. A display device 6 and an input device 7 . The fingerprint sensing module 2 is disposed on the case 1 and has a finger contact area 21 exposed on the surface of the case 1. The finger contact area 21 is used for finger contact to capture fingerprints. The sterilizing light source 3 is arranged on the casing 1 and includes a light-emitting element 31 and a control circuit 32. The light-emitting element 31 can emit ultraviolet rays to irradiate the finger contact area 21. It only needs to cover the finger contact area 21. In this embodiment, the light emitting element 31 is a light emitting diode, but a lamp tube can also be used. The control circuit 32 is electrically connected to the light emitting element 31 and controls the light emitting element 31 to be turned on and off.

The control module 4 is electrically connected with the fingerprint sensing module 2 and the control circuit 32 of the sterilizing light source 3 , and the control module 4 is also electrically connected with the fingerprint data storage unit 5 , the display device 6 and the input device 7 . When the fingerprint sensing module 2 senses that the user touches the finger contact area 21 and captures the fingerprint information, the control module 4 compares the data in the fingerprint data storage unit 5 to identify the fingerprint, and the control module 4 judges the fingerprint sensing module 2 Sensing the signal of finger contact, to send an instruction to the control circuit 32 of the sterilizing light source 3 to turn on the light emitting element 31, so that the light emitting element 31 illuminates the finger contact area 21 for a predetermined time. In other words, after the control module 4 receives the fingerprint information sensed by the fingerprint sensing module 2, it compares it with the data in the fingerprint data storage unit 5. Remove the finger contact area 21, and send an instruction to the control circuit 32 to turn on the light emitting element 31, after a preset period of time, such as 5 seconds, to provide sufficient irradiation time for ultraviolet light to sterilize, and then let the control circuit 32 turn off the light emitting element 31. After the next user touches the finger contact area 21, repeat the same action to achieve the effect of automatic sterilization after each finger contact. In this embodiment, the display device 6 is a general liquid crystal screen for displaying information output by the control module 4 , and the input device 7 is a general keyboard as an interface for inputting information to the control module 4 .

In summary, the fingerprint reader combined with the sterilizing function of the present invention automatically irradiates the finger contact area 21 with ultraviolet light for a predetermined time through the sterilizing light source 3 after the finger touches, to eliminate germs, so as to prevent the fingerprint reader from becoming a medium for spreading germs , to ensure the sanitation and safety of the fingerprint reader.
