Description

Technical Field

[0001] This invention relates to the field of smart door lock cleaning technology, and more specifically, to a cleaning device and a smart door lock having the same. Background Technology

[0002] Currently, when using smart door locks, the locks are generally exposed outside the door, and dust can easily accumulate on and inside the locks over time.

[0003] Furthermore, smart locks typically use fingerprint or numeric keypad unlocking, leaving fingerprints on the input screen. If these fingerprints aren't cleaned, they can pose a security risk. Also, smart locks can easily harbor bacteria or viruses; if not cleaned or disinfected, these residues can easily cause cross-infection between users.

[0004] Smart locks that use both fingerprint and keypad unlocking typically have the fingerprint sensor mounted on the lock handle. While existing technologies include dust covers, these covers are usually separate and independent of each other, resulting in incomplete coverage. Furthermore, although some existing technologies incorporate cleaning components within the dust cover for cleaning the keypad, the aforementioned design prevents simultaneous cleaning of both the fingerprint sensor and the keypad. Therefore, existing smart lock technologies suffer from incomplete and ineffective cleaning. Summary of the Invention

[0033] This invention provides a cleaning device on the lock body 1 of a smart lock. The cleaning device includes a dust cover 10, which covers the lock body 1 to prevent dust from entering. The cleaning device also includes a sweeping mechanism 20, which includes a sweeping component 200. The sweeping mechanism 20 is movably mounted on the dust cover 10 and located within the covered space 100 of the dust cover 10. The sweeping component 200 contacts the lock body 1 to clean and wipe it, removing fingerprints and improving the security of the smart lock. The system ensures the cleanliness of the smart lock body. At least a portion of the cleaning component 200 is movably arranged along the distribution direction of the cleaning component 200 and the lock body 1, such that the cleaning component 200 has a clearance cleaning position for avoiding the lock handle 3 of the lock body 1 or a digital cleaning position for cleaning the digital screen of the lock body 1. Thus, when the cleaning component 200 moves to the lock handle 3, it is in the clearance cleaning position, allowing it to simultaneously clean and wipe both the lock handle 3 and the digital screen of the lock body, thereby ensuring complete cleaning of the lock body and improving its cleanliness.

[0034] like Figure 3 As shown, the cleaning mechanism 20 includes: a first drive assembly 21, which is movably mounted on the dust cover 10; a cleaning component 200 extending along the width direction of the door lock body 1, the cleaning component 200 including a movable cleaning section 201 and a plurality of fixed cleaning sections 202, at least two of the plurality of fixed cleaning sections 202 being spaced apart along the extension direction of the cleaning component 200 to form a clearance space 203 for avoiding the door lock handle 3, the movable cleaning section 201 being movably mounted within the clearance space 203; wherein, the first drive assembly 21 is drivenly connected to the movable cleaning section 201, and both fixed cleaning sections 202 are mounted on the first drive assembly 21.

[0035] In this application, there are two fixed cleaning sections 202; the fixed cleaning sections 202 and the movable cleaning sections 201 are arranged sequentially along the extension direction of the cleaning component 200.

[0036] In the embodiments of this application, when the cleaning component 200 moves to the door lock handle 3, the movable cleaning section 201 moves away from the door lock body 1 to avoid the door lock handle 3 through the clearance space 203.

The cleaning device also includes: a disinfection component 30, which is installed within the shielding space 100; and a second detection component, which is mounted on the door panel 4. When the dust cover 10 shields the door lock body 1, the dust cover 10 presses against the second detection component, so that the second detection component detects a pressure value and controls the operation of the disinfection component 30 or the cleaning mechanism 20 based on the pressure value. The second detection component is a pressure sensor.

[0049] Specifically, when the dust cover is opened and then closed, and the pressure sensor detects a pressure value greater than 0, the disinfection component 30 or the cleaning mechanism 20 is controlled to operate.

[0050] Optionally, the disinfection component 30 includes a liquid storage tank 31 and a spray pipe assembly 32.

[0053] Optionally, the disinfection assembly 30 further includes a pressing component. One end of the pressing component passes through the fixed rod 211 and is connected to the movable rod 212. The other end of the pressing component is a free end. The movement of the movable rod 212 causes the pressing component to move closer to or away from the pressing part of the liquid storage tank 31, so as to press the pressing part of the liquid storage tank 31 through the pressing component.
