Abstract
Description
Technical Field
[0001] This utility model relates to the field of fingerprint lock technology, specifically a fingerprint lock with fingerprint cleaning function. Background Technology
[0002] With the continuous development of technology, fingerprint recognition technology has been widely used in access control systems, smart locks, and other fields due to its high accuracy, high security, and convenience. Fingerprint locks, with their ability to quickly unlock without carrying keys and simply by fingerprint, greatly improve the convenience and security of people's lives, and are gradually becoming an important choice for security equipment in homes and commercial establishments.
[0003] Because the fingerprint recognition module is directly exposed, it is easily damaged by external impacts, prying, and other violent means. Furthermore, criminals may use tools to try to pry open or smash the fingerprint recognition area to bypass the normal unlocking procedure, thus increasing the risk of the lock being illegally opened. If a sliding cover is used, there is no warning function to alert residents when criminals attempt to slide the cover up to damage the fingerprint recognition area. Therefore, we propose a fingerprint lock with fingerprint cleaning function. Utility Model Content
[0004] The purpose of this invention is to provide a fingerprint lock with fingerprint cleaning function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fingerprint lock with fingerprint cleaning function, comprising a fingerprint lock body, a handle provided on the fingerprint lock body, a fingerprint groove opened on the fingerprint lock body and a fingerprint component provided in the fingerprint groove, and further comprising: A dustproof component, comprising a sliding cover disposed on the fingerprint lock body, wherein sliding grooves are provided on both sides of the fingerprint lock body near the sliding cover, and a slider is slidably connected in the sliding grooves, and the sliding cover is fixedly connected to the slider. The protective component includes a fixing plate fixed to the sliding cover, a connecting seat at the bottom of the fixing plate, a limit plug at the bottom of the connecting seat, a stop member connected to the bottom of the limit plug, a fixing seat on the side of the fingerprint lock body near the stop member, a housing on the fixing seat, a first spring inside the housing, a limit ball connected to the first spring, the limit ball being slidably connected inside the housing, and a button on the side of the fingerprint lock body near the limit ball.
[0006] Furthermore, a warning component is provided on the top of the fingerprint lock body. The warning component includes a mounting shell, an extension plate is provided on the mounting shell, and a bolt is threadedly connected between the extension plate and the fingerprint lock body.
[0007] The above technical solution involves setting up an early warning component. When the contact element is separated from the button, the early warning component will activate to alert the resident.
[0008] Furthermore, a cleaning component is provided on the side of the sliding cover near the fingerprint sensor. The cleaning component includes a brush disk, and a second spring is fixedly connected between the brush disk and the sliding cover.
[0009] The above technical solution involves setting up a cleaning component to clean the fingerprint on the fingerprint sensor, preventing it from affecting fingerprint recognition.
[0010] Furthermore, a telescopic rod is provided on the side of the sliding cover near the brush disc, and the telescopic rod is fixedly connected to the brush disc.
[0011] The above technical solution involves using a telescopic rod to provide stability during the extension and retraction of the brush plate.
[0012] Furthermore, the fingerprint lock body is provided with an auxiliary component, which includes a hidden shell and a paddle inside the hidden shell.
[0013] The above technical solution is adopted: by setting an auxiliary component, when the user moves the lever before sliding the cover, the warning component will not work.
[0014] Furthermore, an alarm is installed inside the mounting housing.
[0015] The above technical solution involves setting up an alarm to issue a warning.
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a protective component, it is possible to effectively prevent others from directly accessing the fingerprint recognition module to crack the password or forcibly open it through illegal means. This solves the problem that the fingerprint recognition module is directly exposed to the outside and is easily damaged by external impacts, prying, and other violent forces. Furthermore, criminals may use tools to try to pry open or smash the fingerprint recognition area to bypass the normal unlocking procedure, thereby increasing the risk of the door lock being illegally opened. In addition, the sliding cover does not provide a warning function to the resident when criminals attempt to slide the cover up to damage the fingerprint recognition area. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a fingerprint lock with fingerprint cleaning function, including a fingerprint lock body 1, a handle 2 provided on the fingerprint lock body 1, a fingerprint groove 3 opened on the fingerprint lock body 1, and a fingerprint component 9 provided in the fingerprint groove 3, and further including: Dustproof component 4 includes a sliding cover 41 disposed on the fingerprint lock body 1. Slide grooves 42 are provided on both sides of the fingerprint lock body 1 near the sliding cover 41. A slider is slidably connected in the slide grooves 42. The sliding cover 41 is fixedly connected to the slider. The protective component 5 includes a fixing plate 51 fixed on the sliding cover 41, a connecting seat 52 at the bottom of the fixing plate 51, a limit plug 53 at the bottom of the connecting seat 52, a stop 54 connected to the bottom of the limit plug 53, a fixing seat 55 on the side of the fingerprint lock body 1 near the stop 54, a housing 56 on the fixing seat 55, a first spring 57 inside the housing 56, a limit ball 58 connected to the first spring 57, the limit ball 58 slidingly connected inside the housing 56, and a button 59 on the side of the fingerprint lock body 1 near the limit ball 58. Specifically, the sliding cover 41 is first slid down in the slide groove 42 by the slider, which then drives the fixing plate 51 and the bottom limiting block 53 to move downward. When the limiting block 53 contacts the limiting ball 58, it will squeeze the limiting balls 58 on both sides to retract into the housing 56 through the first spring 57. When the groove on the limiting block 53 is at the same level as the limiting ball 58, the limiting ball 58 is fixed in the groove by the elastic force of the first spring 57. At the same time, the abutment 54 at the bottom of the limiting block 53 will contact the button 59. When a criminal attempts to slide the sliding cover 41 up to identify the fingerprint area, the abutment 54 will separate from the button 59, and the warning component 6 will be activated.
[0024] Furthermore, such as Figure 1 As shown: The fingerprint lock body 1 is provided with a warning component 6 on the top. The warning component 6 includes a mounting shell 61, an extension plate 62 is provided on the mounting shell 61, and a bolt 63 is threadedly connected between the extension plate 62 and the fingerprint lock body 1. An alarm is provided inside the mounting shell 61. When the stop 54 is separated from the button 59, the alarm inside the mounting shell 61 will sound an alarm, thereby reminding the residents and also warning criminals. The above solutions also have the drawback that when a large number of fingerprints remain on the fingerprint sensor 9 over a long period of time, the fingerprint recognition capability will weaken, such as... Figure 4 As shown: A cleaning component 8 is provided on the side of the sliding cover 41 near the fingerprint component 9. The cleaning component 8 includes a brush plate 81. A second spring 83 is fixedly connected between the brush plate 81 and the sliding cover 41. A telescopic rod 82 is provided on the side of the sliding cover 41 near the brush plate 81. The telescopic rod 82 is fixedly connected to the brush plate 81. When the sliding cover 41 is slid, the brush plate 81 will be driven to retract and reset through the second spring 83 and the telescopic rod 82, thereby cleaning the fingerprint on the fingerprint component 9 in the fingerprint groove 3. The above solution also has the problem that when the user needs to open the sliding cover 41, the warning component 6 cannot stop working, such as... Figure 3 As shown: The fingerprint lock body 1 is provided with an auxiliary component 7, which includes a hidden shell 71 and a paddle 72 inside the hidden shell 71. When the user slides the sliding cover 41, the paddle 72 is moved, and the warning component 6 will not work. The working principle provided by this utility model is as follows: Figures 1-4As shown: First, the sliding cover 41 slides downwards in the slide groove 42 via the slider, which then drives the fixing plate 51 and the bottom limiting block 53 to move downwards. When the limiting block 53 contacts the limiting ball 58, it will squeeze the limiting balls 58 on both sides to retract into the housing 56 through the first spring 57. When the groove on the limiting block 53 is at the same level as the limiting ball 58, the limiting ball 58 is locked in the groove by the elastic force of the first spring 57. At the same time, the abutment 54 at the bottom of the limiting block 53 will engage with the button 59. When a criminal attempts to slide the cover 41 up to identify the fingerprint area, the alarm inside the housing 61 will sound after the stop 54 separates from the button 59, thus reminding the resident and also warning the criminal. While sliding the cover 41, the brush plate 81 will retract and reset through the second spring 83 and the telescopic rod 82, thereby cleaning the fingerprint on the fingerprint component 9 in the fingerprint slot 3. If the user moves the lever 72 before sliding the cover 41, the warning component 6 will not work.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
