Description

Technical Field

[0001] This utility model belongs to the field of cleaning technology, specifically relating to a fingerprint removal device for fingerprint locks. Background Technology

[0002] In today's society, fingerprint locks are widely used in various places, providing people with a convenient way to unlock doors. However, with increased usage, a large number of fingerprints remain on the fingerprint module. These residual fingerprints not only affect the appearance but may also pose security risks, such as allowing others to crack the lock using these residual fingerprints.

[0003] Traditional fingerprint locks often lack effective fingerprint removal devices, requiring users to wipe them manually, which is inconvenient and ineffective. Moreover, conventional cleaning methods cannot automatically clean the fingerprints while unlocking, failing to meet people's needs for an efficient and convenient lifestyle. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient and clean fingerprint removal device for fingerprint locks in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A fingerprint erasure device for a fingerprint lock includes a fingerprint lock body and a panel disposed on the fingerprint lock body. The panel is provided with a fingerprint module, and a sliding cover is slidably disposed on the fingerprint lock body.

[0007] It also includes:

[0008] A storage bottle, which is mounted on a sliding cap, stores cleaning solution in the storage bottle;

[0009] A limiting plate is provided on the fingerprint lock body to restrict the opening and closing position of the sliding cover;

[0010] A piston-discharge mechanism is provided on a sliding cover. When the sliding cover is opened, a limiting plate presses the piston-discharge mechanism to discharge liquid.

[0011] A cleaning plate is mounted on a sliding cover, and the cleaning plate is moistened after liquid is dispensed by the piston liquid dispensing mechanism.

[0012] As a further optimization of this utility model, the piston liquid discharge mechanism includes a mounting box, which is disposed through the sliding cover and in the liquid storage bottle. A piston is slidably disposed in the mounting box, and a pressure plate is disposed on the piston. A spring is disposed between the pressure plate and the sliding cover. An inlet and an outlet are disposed on both sides of the mounting box, and a one-way valve is disposed in the inlet and outlet.

[0013] As a further optimization of this utility model, the sliding cover is provided with a limiting ridge, and the two ends of the limiting ridge are provided with limiting grooves.

[0014] As a further optimization of this utility model, a torsion spring is provided between the limiting plate and the fingerprint lock body, the limiting plate can be embedded in the limiting groove, and the pressure plate and the lower limiting groove are in the same row.

[0015] As a further optimization of this utility model, a T-shaped conduit is provided on the liquid outlet of the installation box, and the T-shaped conduit is disposed in the cleaning plate.

[0016] As a further optimization of this utility model, the cleaning plate can contact the surface of the fingerprint module, and the surface of the sliding cover is made of frosted material.

[0017] The beneficial effects of this utility model are as follows:

[0018] Unlike existing technologies, in actual use, when the sliding cover is opened to a specific position, the limiting plate squeezes the pressure plate, causing the piston to move. The cleaning fluid flows to the cleaning plate through the T-shaped conduit, thus preventing the cleaning plate from drying out. During the process of closing the sliding cover, fingerprints can be automatically wiped away, resulting in a good cleaning effect. This effectively ensures the security and cleanliness of the fingerprint lock, greatly enhancing the user experience. Attached Figure Description

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figure 1 - Figure 6 As shown, a fingerprint clearing device for a fingerprint lock includes a fingerprint lock body 1 and a panel 2 disposed on the fingerprint lock body 1. A fingerprint module 4 is disposed on the panel 2, and a sliding cover 3 is slidably disposed on the fingerprint lock body 1.

[0029] It also includes:

[0030] The liquid storage bottle 6 is mounted on the sliding cover 3 and stores cleaning solution in the liquid storage bottle 6;

[0031] Limiting plate 5 is set on the fingerprint lock body 1, and the opening and closing position of sliding cover 3 is restricted by limiting plate 5;

[0032] The piston discharge mechanism 8 is mounted on the sliding cover 3. When the sliding cover 3 is opened, the limiting plate 5 presses the piston discharge mechanism 8 to discharge liquid.

[0033] Cleaning plate 7 is mounted on sliding cover 3. After liquid is discharged from piston liquid discharge mechanism 8, cleaning plate 7 is moistened.

[0034] The piston dispensing mechanism 8 includes a mounting box 81, which is disposed through the sliding cover 3 and inside the storage bottle 6. A piston 84 is slidably disposed in the mounting box 81, and a pressure plate 82 is disposed on the piston 84. A spring 83 is disposed between the pressure plate 82 and the sliding cover 3. An inlet and an outlet are disposed on both sides of the mounting box 81, and a one-way valve 85 is disposed in the inlet and outlet. The piston 84 moves when the pressure plate 82 is squeezed, and the one-way valve 85 controls the entry and exit of the cleaning fluid.

[0035] The sliding cover 3 is provided with a limiting ridge 31, and the limiting ridge 31 has limiting grooves 32 at both ends. A torsion spring 51 is provided between the limiting plate 5 and the fingerprint lock body 1. The limiting plate 5 can be embedded in the limiting groove 32. The pressure plate 82 is in the same row as the lower limiting groove 32. When the sliding cover 3 is opened, the limiting plate 5 uses the torsion spring to reset and embed itself in the limiting groove 32, and squeezes the pressure plate 82 of the piston liquid discharge mechanism 8 at a specific position to control the triggering of the cleaning liquid flow.

[0036] A T-shaped conduit 9 is provided on the liquid outlet of the mounting box 81. The T-shaped conduit 9 is installed in the cleaning plate 7, and the cleaning liquid on the cleaning plate 7 is evenly distributed through the T-shaped conduit 9.

[0037] The cleaning plate 7 can contact the surface of the fingerprint module 4, and the surface of the sliding cover 3 is made of frosted material to prevent fingerprints from being left on the surface of the sliding cover 3.

[0038] It should be noted that the working principle of this fingerprint lock cleaning solution is as follows: When unlocking using the fingerprint module 4, the sliding cover 3 slides open along the fingerprint lock body 1. The limiting ridge 31 and limiting groove 32 on it cooperate with the limiting plate 5 on the fingerprint lock body 1 to limit the opening and closing position. The limiting plate 5 is reset by the torsion spring 51 and can be embedded in the limiting groove 32 during the sliding process. The liquid storage bottle 6 is placed on the sliding cover 3 and contains cleaning liquid. When the sliding cover 3 is opened to a certain position, the limiting plate 5 is embedded in the limiting groove 32 and squeezes the pressure plate 82 of the piston liquid dispensing mechanism 8. The pressure plate 82 is compressed under the action of the spring 83, which drives the mounting box 8. The piston 84 inside the housing moves, and the mounting box 81 passes through the sliding cover 3 and is placed in the liquid storage bottle 6. The movement of the piston 84 causes the cleaning fluid to flow out from the outlet and flow through the T-shaped conduit 9 to the cleaning plate 7. After unlocking, the sliding cover 3 is closed. At this time, the limiting plate 5 no longer presses on the pressure plate 82. Under the action of the spring 83, the pressure plate 82 is reset, and the one-way valve 85 of the inlet on the mounting box 81 is opened and the one-way valve 85 of the outlet is closed, guiding the cleaning fluid in the liquid storage bottle 6 into the mounting box 81. During the process of closing the sliding cover 3, the moistened cleaning plate 7 comes into contact with the surface of the fingerprint module 4 and wipes to remove fingerprints.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
