TECHNICAL FIELD

[0001] The utility model relates to a household door sealing and heat preservation technical field, specifically a full -automatic household door sealing device. BACKGROUND

[0002] The household door is the first door to enter a house, also called the entrance door. In the northern cold region of China, such as the three provinces of northeast China, Inner Mongolia and other regions, the sealing of the household door has been a long-standing problem. If the door gap sealing technology of the household door is insufficient, the indoor temperature will drop quickly, the house will be poorly insulated, and frost will form on the door gap, which will seriously reduce the comfort of residents.

[0003] At present, some household doors with air bags around the door gap have appeared on the market, which realize the sealing of the door gap by expanding the air bags, but they have the problems of complex overall structure, inconvenient operation and the like, do not have practicality, and cannot be popularized and used in actual life.

[0004] At the same time, the existing household door is mainly composed of a door body and a door lock. With the improvement of residents' life experience, the appearances of the door locks are different, but the working principles behind them are similar. The most commonly used working principle is still to rotate the internal door lock spindle to move the transmission plate forward and backward, realize the movement of the door latch, and then realize the opening or closing of the door.

[0005] Therefore, on the basis of the existing door latch structure, further combined with the air bag sealing technology, we design a full-automatic household door sealing device. Under the cooperation of multiple sensors and air compressors, the air bag can be deflated by rotating the door handle, and the door can be easily opened. After the household door is closed, the air bag can be automatically inflated after the door latch is reset, realizing the sealing of the door gap. The overall structure is simple and novel, the design is scientific and reasonable, and the practicality is strong. It can effectively solve the problem of insufficient door gap sealing technology in cold regions. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment 1

[0025] Please refer to Figures 1-6 The embodiment provides a full-automatic house door sealing device, which comprises a sealing main plate 2 arranged at the back of a door body 1, air bag grooves 5 arranged at four sides of the sealing main plate 2, air bags 6 arranged in the air bag grooves 5, a main control plate 22, an air bag inflation and deflation assembly, a door lock sensing assembly and a door body sensing assembly; wherein the design of the air bag grooves 5 and the air bags 6 is a conventional design familiar to those skilled in the art, and the application will not be described in detail.

[0026] The air bag inflation and deflation assembly is used for controlling the inflation and deflation of the air bags 6, and the main control plate 22 is used for controlling the work of the air bag inflation and deflation assembly. Specifically, as shown in the drawing, Figures 1-3As shown, the air bag inflation and deflation assembly includes a main control box 4 arranged on the sealing main plate 2, and an air compressor 7 is arranged in the main control box 4. The air compressor 7 can also be a conventional air supply device such as an air pump, and is a conventional structure familiar to those skilled in the art, and will not be described here. The air compressor 7 is connected with the main air pipe 8 through an electromagnetic valve 10, and the main air pipe 8 is connected with the air bag 6 through a plurality of branch air pipes 9. The air compressor 7 and the electromagnetic valve 10 are electrically connected with the main control plate 22. Among them, the electromagnetic valve 10 is a conventional general accessory, and will not be described here. As shown in Figure 2 As shown, as a conventional design familiar to those skilled in the art, in order to realize the installation of the air pipe, an installation cavity 11 is arranged in the sealing main plate 2, and the main control box 4, the main air pipe 8 and the branch air pipe 9 are arranged in the installation cavity 11. As shown in Figure 3 As shown, the overall visual effect is improved by installing a decorative baffle outside the installation cavity 11. At the same time, according to the needs, a ventilation hole should be arranged outside the main control box 4 to facilitate the work of the internal air compressor 7. At the same time, it should be pointed out that the installation of the sealing main plate 2 should not affect the use of the door lock 3 on the door body 1, and a pre-prepared hole slot should be arranged on the sealing main plate 2 for the door lock 3 to pass through the outside body, and the door lock 3 can be assembled by being clamped into the hole slot. It is a conventional knowledge familiar to those skilled in the art, and will not be described here.

[0027] Secondly, the door lock sensing assembly is used to sense the opening and closing state of the door latch 17 and transmit the signal to the main control plate 22. It should be pointed out that the door lock sensing assembly capable of realizing this function should be a conventional design familiar to those skilled in the art, which can be obtained by customization and purchase. In this embodiment, as shown in Figure 4 As shown, preferably, the door lock sensing assembly includes a tail plate 13 fixedly arranged at the tail of the transmission plate 12, the tail of the tail plate 13 is connected with a pressing plate 15 through a spring 14, the pressing plate 15 is connected with a pressure sensor 16, the pressure sensor 16 is fixedly arranged in the door body 1, and the pressure sensor 16 is electrically connected with the main control plate 22. Among them, the transmission plate 12 is a accessory for driving the door latch 17 to move backward, which is a traditional conventional accessory in the door lock 3, and is a conventional door lock accessory familiar to those skilled in the art. After rotating the handle, the door lock main shaft 18 will drive the transmission plate 12 to move backward, thereby opening the door latch 17. When the transmission plate 12 moves backward, the tail plate 13 will press the spring 14, and the pressure sensor 16 will transmit the signal to the main control plate 22 after being stressed, and then the main control plate 22 controls the electromagnetic valve 10 to open, realizing the deflation of the air bag 6.

[0028] Furthermore, the door sensing component is used to sense the opening and closing state of the door 1 and transmit the signal to the main control board 22. As a conventional design familiar to those skilled in the art, the sensor used to sense the opening and closing state of the door 1 is an existing conventional and common structure. In this application, the door sensing component preferably adopts a proximity switch 23 set on the door 1, which can be obtained by custom purchase and will not be described in detail. Example 2

[0029] Based on Embodiment 1, in order to realize the sensing of the state of the latch 17 in the door lock 3, this embodiment further provides another implementation of the door lock sensing component. Specifically, in conjunction with... Figure 5 As shown, the door lock sensing assembly includes a drive gear 19 fixedly sleeved on the door lock main shaft 18, and a driven gear 20 rotatably disposed inside the door body 1, meshing with the drive gear 19. The driven gear 20 is connected to a rotation angle sensor 21, which is fixedly disposed inside the door body 1 and electrically connected to the main control board 22. It should be noted that the door lock main shaft 18 is a conventional door lock structure familiar to those skilled in the art, and its working principle has been described in the above embodiment 1, and will not be repeated in this embodiment. When the door handle is turned, causing the door lock main shaft 18 to rotate, the door lock main shaft 18 drives the driven gear 20 to rotate through the drive gear 19, which in turn drives the rotation shaft of the rotation angle sensor 21 to rotate. The rotation angle sensor 21 can then transmit a signal to the main control board 22, which in turn controls the solenoid valve 10 to open, thereby deflating the airbag 6.

[0030] In this application, the overall working principle is as follows: when the door lock sensing component senses that the door latch 17 is open, the main control board 22 controls the airbag inflation and deflation component to work, so that the airbag 6 is deflated; when the door lock sensing component senses that the door latch 17 is closed, and the door sensing component senses that the door body 1 is closed, the main control board 22 controls the airbag inflation and deflation component to work, so that the airbag 6 is inflated.

[0031] It should be noted that, as a routine operation familiar to those skilled in the art, in actual application, the pressure sensor 16 reaches a certain pressure, or the rotating shaft of the rotation angle sensor 21 rotates to a certain angle, and then the main control board 22 controls the electromagnetic valve 10 to open to realize the deflation of the air bag 6. When the air bag 6 needs to be inflated, the inflation should be carried out when the door body 1 is in the closed state. At this time, the proximity switch 23 transmits the signal of the closed door body 1 to the main control board 22, and the door latch 17 in the door lock 3 is reset. At this time, the signal value transmitted by the pressure sensor 16 or the rotation angle sensor 21 belongs to the interval of the reset of the door latch 17. At this time, the main control board 22 controls the electromagnetic valve 10 to open, and makes the air compressor 7 work, so that the air bag 6 is inflated. Then the air compressor 7 stops working, and the electromagnetic valve 10 is closed, and the inflation of the air bag 6 is completed. After the air bag 6 is inflated, the outside pushes against the door frame around the door body 1 to realize the sealing of the door gap.

[0032] It should be noted that the setting of the signal value can be realized by programming control of the main control board 22. The electrical connection diagram of the main control board 22, the air compressor 7, the electromagnetic valve 10, the pressure sensor 16 or the rotation angle sensor 21 and the proximity switch 23 is shown in Figure 6 The internal code and circuit setting should be a routine setting familiar to those skilled in the art, which can be directly customized and obtained, and will not be described in detail.

[0033] In addition, it should be noted that, as a routine setting familiar to those skilled in the art, the installation of the door lock sensing assembly in the door body 1 should be a routine operation familiar to those skilled in the art. Only the corresponding installation cavity needs to be opened in the door lock main shaft 18 or the transmission plate 12, and the customization can be obtained, and will not be described in detail.

[0034] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, the solutions or features belonging to the prior art or common knowledge are not described in detail in the above embodiments.

[0035] In addition, the technical solutions of the present application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
