Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, and relates to a pet door, specifically an electric pet door. Background Technology

[0002] As people's living standards improve, many families keep pets, especially cats or dogs. Pets bring joy to people's lives, and more and more families treat their pets as family members, providing them with a good living environment. To facilitate pets' access, people often install pet doors. Most existing pet doors only have two modes: open and close, making their function relatively simple.

[0003] Upon investigation, Chinese patent number 202320433748.5, entitled "A Pet Door," includes an outer door frame, a door panel rotatably connected to the outer door frame, and a switch. The switch includes a knob, a first blocking member, and a second blocking member. When the switch is rotated to the point where the first blocking member blocks the outside of the door panel and the second blocking member blocks the inside of the door panel, the switch locks the door panel. When the switch is rotated to the point where the first blocking member releases its obstruction of the outside of the door panel and the second blocking member releases its obstruction of the inside of the door panel, the door panel can rotate to the outside or inside of the outer door frame. When the switch is rotated to the point where the first blocking member releases its obstruction of the outside of the door panel and the second blocking member releases its obstruction of the inside of the door panel, the door panel can rotate to the outside or inside of the outer door frame. When the switch is turned to the point where the first blocking member releases its obstruction of the outer side of the door panel and the second blocking member blocks the inner side of the door panel, the door panel can only rotate outwards towards the outer side of the outer door frame. When the switch is turned to the point where the first blocking member blocks the outer side of the door panel and the second blocking member releases its obstruction of the inner side of the door panel, the door panel can only rotate inwards towards the inner side of the outer door frame. The key feature is that the first blocking member and the knob are integral parts; the first blocking member is recessed inwards to form a mounting groove; the second blocking member has a mounting part that limits its movement within the mounting groove; and the second blocking member is connected and fixed to the first blocking member through the mounting part. This pet door has four functions: allowing entry and exit, preventing entry and exit, allowing entry only and exit only, and allowing exit only and no entry. However, it can only be operated manually, which is relatively cumbersome.

[0004] Furthermore, Chinese patent number 202320453996.6, entitled "An Electronic Pet Door," includes an outer door frame and a door panel rotatably connected to the outer door frame. Its key feature is that it further includes an identity authentication module, a controller, and an electric lock mechanism. The output of the identity authentication module is connected to the input of the controller, and the output of the controller is connected to the electric lock mechanism. After confirming the identity authentication information, the identity authentication module sends it to the controller, which then controls the electric lock mechanism to change the opening and closing state of the door panel. This pet door has an identity authentication module that can authenticate the pet's identity information and automatically control the opening and closing of the door panel through identity recognition. However, it has a complex structure, high cost, and is also troublesome to maintain. Summary of the Invention

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figures 1-7 As shown, an electric pet door includes an outer door frame 1, an inner door frame 2, a door panel 3 rotatably mounted on the outer door frame 1, a rotary switch 4, and a push switch 5. A controller and a servo motor 8 that drives the rotary switch 4 are installed inside the outer door frame 1. Indicator lights displaying various operating modes, such as "can enter and exit," "cannot enter or exit," "can only enter and exit," and "can only exit and not enter," are also installed on the outer door frame 1. One output of the controller is connected to the servo motor 8, and one input of the controller is connected to the grounded push switch 5. Switching between the various modes is achieved through the push switch 5. Typically, the controller is connected to four indicator lights displaying the operating modes, and the rotary switch 4 has four different mating structures with the door panel 1.

[0027] Finally, the operating mode may also include an authentication mode, which includes an authentication module 10, the output of which is connected to one input of the controller.

[0028] The specific structure is as follows: the front end of the inner door frame 2 protrudes forward and is provided with a first frame 21 that matches the door hole for installing the door body. The outer door frame 1 is formed by the front frame 11 and the rear frame 12. The rear end of the front frame 11 protrudes backward and is provided with a second frame 111 that matches the first frame 21. The second frame 111 passes through the rear frame 12 and is inserted into the first frame 21 of the inner door frame 2 to form a channel. The door panel 3 is installed inside the front frame 11. The upper left and right sides of the door panel 3 are provided with rotating convex shafts 31. The upper inner wall of the front frame 11 is provided with corresponding shaft holes 114 on the left and right sides. The upper end of the door panel 3 is suspended on the front frame 11 and is rotatably connected to the outer door frame 1 through the cooperation of the rotating convex shaft and the shaft hole. The front frame 11 has a circular hole 112 for mounting the rotary switch 4 and mounting holes for mounting the push switch 5 and indicator light 6 at its bottom front end. The servo motor 8 and controller 9 are mounted in the cavity formed by the mating of the front frame 11 and the rear frame 12. Typically, the push switch 5, indicator light 6, and controller 9 are arranged on a circuit board. The servo motor 8 is fixed by a motor mount 80, and the output shaft of the servo motor 8 is connected to the rotary switch 4. The outer lampshade of the indicator light 6 has three-dimensional markings corresponding to the four working modes.

[0029] An induction coil 7 is installed inside the outer door frame 1 to sense the pet's identity information for verification. The identity authentication module 10 includes a reader / writer and an identity authentication card carried on the pet. The electromagnetic waves emitted by the reader / writer read the information on the identity authentication card within a certain range and send it to the controller. The controller controls the servo motor 8 to rotate, thereby driving the rotary switch 4 to change the opening and closing state of the door panel 3. Specifically, the reader / writer is an RF reader / writer, and the identity authentication card is an RF chip encapsulated with an induction antenna. The RF reader / writer and the identity authentication card complete the read / write operation via radio waves. Alternatively, the communication method between the reader / writer and the identity authentication card can be one of NFC, Wi-Fi, Zigbee, or Bluetooth.

[0030] The rotary switch 4 has the same structure as patent number 202320433748.5. The rotary switch 4 includes a knob 41, a first blocking member 42, and a second blocking member 43. The first blocking member 42 and the knob 41 are integral parts. The first blocking member 42 is recessed inward to form a mounting groove. The second blocking member 43 has a mounting portion that limits and cooperates with the mounting groove. The second blocking member 43 is connected and fixed to the first blocking member 42 through the mounting portion. When the switch 4 is rotated to the point where the first blocking member 42 blocks the outside of the door panel 3 and the second blocking member 43 blocks the inside of the door panel 3, the rotary switch 4 opens the door panel 3... Locking mechanism: When the rotary switch 4 is rotated to the point where the first blocking member 42 releases its obstruction of the outer side of the door panel 3 and the second blocking member 43 releases its obstruction of the inner side of the door panel 3, the door panel 3 can rotate to the outside or inside of the outer door frame 1; when the rotary switch 4 is rotated to the point where the first blocking member 42 releases its obstruction of the outer side of the door panel 3 and the second blocking member 43 blocks the inner side of the door panel 3, the door panel 3 can only rotate to the outside of the outer door frame 1; when the rotary switch 4 is rotated to the point where the first blocking member 42 blocks the outside of the door panel 3 and the second blocking member 43 releases its obstruction of the inner side of the door panel 3, the door panel can only rotate to the inside of the outer door frame 1. The rotary switch 4 is rotatably connected to the bottom of the outer door frame 1, and the bottom of the outer door frame 1 is provided with a receiving groove 113 for accommodating the first blocking member 42 and the second blocking member 43. Mounting holes are respectively opened at the four corners of the outer door frame 1 and the inner door frame 2. The outer door frame 1 and the inner door frame 2 are installed on the mounting door body by bolts, and sealing gaskets are respectively embedded in the inner side edges of the outer door frame 1 and the inner door frame 2.

[0031] In addition, door panel 3 is made of plastic mesh, which is lightweight and has a certain degree of elasticity, making it easy for pets to push open without causing them harm.

[0032] Finally, the edge of the door panel 3 is provided with a brush, the bottom of the door panel is provided with a first magnetic block 32, and the lower end of the window of the outer door frame 1 is provided with a corresponding second magnetic block 14. After the door panel 3 is suspended, the lower end is attracted to the second magnetic block 14. The door panel 3 closes the passage through the attraction of the first magnetic block and the second magnetic block.

[0033] During operation, the desired working mode can be selected by pressing the button switch 5. The controller knows the selected working mode based on the number of times the input terminal is grounded. At this time, the corresponding indicator light 6 lights up. At the same time, the controller outputs an execution signal to make the servo motor 8 rotate, which drives the rotary switch 4 to rotate to the corresponding engagement state to engage with the door panel 3, so that the electric pet door can enter and exit, not enter or not exit, only enter and not exit, only exit and not enter, or be in an identity authentication state. In case of power failure, the switch 4 can be manually rotated to be in the corresponding working mode. Since there is an induction coil 7, the pet can be identified to prevent outside pets from entering.

[0034] Example 2

[0035] The circuit module diagram in this embodiment is as follows: Figure 8 The identity authentication module 10 is omitted, but otherwise it is the same as in Example 1.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
