DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual Figure 1-Figure 7 A bathroom lock with an alarm function comprises a front panel 1 for installation outside a door, a rear panel 2 for installation inside the door, and a lock body 3 arranged between the front panel 1 and the rear panel 2.

[0026] Specifically, the lock body 3 includes a shell 31, a lock tongue 32 is slidably provided at one end of the shell 31, and the lock tongue 32 extends out of the shell 31 when the door is closed. An elastic component 30 is provided at one end of the lock tongue 32 located inside the shell 31, wherein the elastic component 30 is a torsion spring. A movable frame 34 is slidably installed inside the shell 31, and the movable frame 34 is fixedly installed with the lock tongue 32. Side openings 341 are provided on both sides of the movable frame 34. A shift block 35 is rotatably connected inside the shell 31, and both sides of the shift block 35 have shift heads 351, which extend into the inner side of the side opening 341, and a square rod 5 is inserted in the middle of the shift block 35. The front panel 1 and the rear panel 2 are rotatably connected to the front door handle 11 and the rear door handle 21, respectively, and the front door handle 11 and the rear door handle 21 are connected to the two ends of the square rod 5, respectively.

[0027] A buckle box is installed on the door frame, a magnet is installed in the buckle box, and a magnet is also installed at the front end of the lock tongue 32. When the door is closed, the two magnets attract each other, and the lock tongue 32 is attracted into the buckle box to achieve the purpose of locking the door. When the door needs to be opened, the front door handle 11 or the rear door handle 21 is turned to drive the square rod 5 to rotate, and the square rod 5 drives the shift block 35 to rotate, and the shift block 35 pushes the side opening 341 through the shift head 351, so that the movable frame 34 pulls the lock tongue 32 to move to the inside of the shell 31 to achieve the purpose of opening the door. The two ends of the elastic component 1 30 are respectively connected to the lock tongue 32 and the shell 31. The elastic component 1 30 is used to pull the lock tongue 32, so that the lock tongue 32 is kept at the inside position of the shell 31 when the door is opened.

[0028] Refer to the instruction manual Figure 1-Figure 7 A detection component 33 is installed inside the housing 31, and the detection component 33 is used to detect the opening and closing of the door; wherein the detection component 33 is a micro switch. A protrusion 321 is fixedly connected to one side of the lock tongue 32 close to the inside of the housing 31, and the protrusion 321 is used to touch the contact of the detection component 33.

[0029] It should be noted that when the door is opened, the lock tongue 32 moves toward the inside of the shell 31, thereby driving the protrusion 321 to touch the contact of the detection component 33, so that the detection component 33 detects that the door is in the open state at this time, and when the lock tongue 32 moves out of the shell 31, the protrusion 321 leaves the contact of the detection component 33, so that the detection component 33 detects that the door is in the closed state at this time.

[0030] Furthermore, a detection device 4 is installed on the rear panel 2, and the detection device 4 is used to detect whether there is someone in the room; wherein the detection device 4 is an infrared sensor.

[0031] It should be noted that the infrared sensor can detect whether there is someone inside the door (in the bathroom).

[0032] Furthermore, the bathroom lock also includes an alarm device, which is used to alarm after a set time interval when a person in the room closes the door. Specifically, the alarm device includes a control module, a communication module and a timing module. The timing module is used to calculate whether the time after the person in the room closes the door exceeds the set time, and the control module is used to send the alarm information to the smart device through the communication module to alarm.

[0033] It should be noted that when someone uses the bathroom, the user closes the bathroom door. On the one hand, the detection component 33 can detect that the door is already closed, and on the other hand, the detection device 4 can detect that there is someone in the bathroom. Under this premise, the timing module starts timing from the time when the person in the room closes the door. After a set time interval, if the bathroom door is not opened, an alarm is triggered. Specifically, when an alarm is triggered, the control module sends the alarm information to the smart device through the communication module. The smart device can be a smart phone or a smart watch. The smart phone or smart watch sends an alarm sound to remind family members that the bathroom usage time exceeds the set time and the person in the bathroom may be in danger.

[0034] Furthermore, a circuit board is provided in the rear panel 2, and the control module, the communication module and the timing module are integrated on the circuit board, and a battery box 7 is installed on the inner side of the rear panel 2, and the battery box 7 is used to install a power supply module. The power supply module can be a lithium battery or a dry cell.

[0035] The above technical solution uses the detection component 33 to determine whether the door is closed, and uses the detection device 4 to determine whether there is someone in the bathroom, so that an alarm can be triggered when the user uses the bathroom for more than the set time. It can also trigger an alarm in time when an elderly or disabled person has an accident in the bathroom to ensure timely treatment.

[0036] Refer to the instruction manual Figure 1-Figure 6 A reverse locking assembly 6 is installed on the rear panel 2. The reverse locking assembly 6 includes a fixing ring 61 and an elastic component 60. The elastic component 60 is used for resetting the fixing ring 61 after rotation. The fixing ring 61 is fixedly installed with the square rod 5. A block 611 is provided at the edge of the fixing ring 61. A locking plate 62 is slid in the rear panel 2. A locking groove 621 is provided at the bottom of the locking plate 62. When the locking groove 621 is inserted into the block 611, the square rod 5 is locked.

[0037] Furthermore, the anti-locking assembly 6 also includes a knob 63 rotatably arranged on the rear panel 2, a pin shaft 64 is fixedly connected to the edge position of one end of the knob 63, a slide groove 622 is opened on one side of the upper end of the locking plate 62, and the pin shaft 64 moves the locking plate 62 by pushing the slide groove 622.

[0038] It should be noted that when using the bathroom, the knob 63 can be turned, and the knob 63 drives the pin 64 to rotate downward, and the pin 64 pushes the locking plate 62 downward through the slide groove 622, so that the locking groove 621 is inserted into the block 611. At this time, the front door handle 11 and the rear door handle 21 cannot be turned to open the door, that is, the purpose of reverse locking is achieved. When unlocking, the knob 63 is rotated in the opposite direction to drive the locking plate 62 to move upward and disengage from the block 611. Among them, the elastic component 60 is a torsion spring.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
