[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] To make the above objects, features, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0030] Refer to Figures 1-6, the present invention provides an automatic door-closing device, including a fixed seat, one end of the fixed seat is fixed, an elastic clamping member is arranged on the fixed seat, the fixed end of the elastic clamping member is fixedly connected to the fixed seat, a magnetic attracting member is arranged in the fixed seat, and the movable end of the elastic clamping member moves through the magnetic attracting member; a pop-up cylinder, sleeved on the fixed seat and arranged corresponding to the door, the inner wall of the pop-up cylinder is detachably connected to the movable end of the elastic clamping member through the magnetic attracting member; a control member, arranged in the fixed seat, and the control member is used for sensing the indoor temperature and driving the magnetic attracting member.

[0031] Fix one end of the fixed seat on the wall, and the pop-up cylinder sleeved on the fixed seat is arranged corresponding to the door. When the door is opened, the door pushes the pop-up cylinder to move towards the wall direction on the fixed seat. After the pop-up cylinder moves a certain distance, the inner wall of the pop-up cylinder is clamped with the elastic clamping member to realize the fixation of the pop-up cylinder. The control member is used for monitoring the indoor temperature. When the indoor temperature drops and the door needs to be closed, the control member sends a signal to make the magnetic attracting member work. The magnetic attracting member corresponds to the movable end of the elastic clamping member and attracts the movable end of the elastic clamping member to release the clamping with the elastic cylinder. The elastic cylinder releases its elastic performance and moves on the fixed seat. The elastic cylinder contacts the door and pushes the door to move to achieve the purpose of closing the door.

[0032] In a further optimized solution, the elastic clamping member includes an elastic clamping buckle 2-3. A through groove for accommodating the elastic clamping buckle 2-3 is formed on the side wall of the fixed seat. The elastic clamping buckle 2-3 is located in the through groove, and the fixed end of the elastic clamping buckle 2-3 is fixedly connected to the fixed seat through a fixing screw 2-4. The movable end of the elastic clamping buckle 2-3 extends into the pop-up cylinder. The movable end of the elastic clamping buckle 2-3 bends and moves under the action of the magnetic attracting member to realize the connection or disassembly between the elastic clamping buckle 2-3 and the pop-up cylinder. That is, when the pop-up cylinder is in the non-pop-up state, the elastic clamping buckle 2-3 is clamped with the pop-up cylinder, and when the pop-up cylinder is in the pop-up state, the elastic clamping buckle 2-3 is separated from the pop-up cylinder.

[0033] It can be understood that the elastic clamping buckle 2-3 includes a connecting plate and a clamping plate fixed on the connecting plate. Among them, one end of the connecting plate is fixed to the fixed seat through a fixing screw 2-4, the connecting plate can be bent, and the clamping plate is used for clamping with the inner wall of the pop-up cylinder.

[0034] Among them, under the action of the magnetic attracting member, the connecting plate bends and drives the clamping plate to release the clamping with the pop-up cylinder. The connecting plate can be adsorbed on the magnetic attracting member or only the clamping plate is released from the clamping with the pop-up cylinder.

[0035] Specifically, the materials of the connecting plate and the clamping plate can be iron or other materials that can be adsorbed by an electromagnet. The connecting plate should have a certain elasticity to achieve reset.

[0036] For a further optimized solution, the magnetic component includes an electromagnet 2-2 fixed inside the fixed seat. The electromagnet 2-2 is arranged corresponding to the movable end of the elastic buckle 2-3 and can adsorb the movable end of the elastic buckle 2-3. The electromagnet 2-2 is used to provide controllable magnetic force, that is, the electromagnet 2-2 can be controllably powered on or off to achieve the attraction or release of the elastic buckle 2-3.

[0037] For a further optimized solution, the fixed seat includes a base 1-1 fixedly connected to the wall. A housing 1-2 is sleeved on the base 1-1. The housing 1-2 includes a connecting cylinder sleeved on the base 1-1. One end of the connecting cylinder away from the base 1-1 is fixedly connected with a sliding cylinder. Among them, both the elastic buckle 2-3 and the electromagnet 2-2 are located inside the sliding cylinder. The base 1-1 is used to fix the fixed seat on the wall, and this wall is the wall corresponding to the door. The connecting cylinder is sleeved on the base 1-1. Among them, the diameter of the connecting cylinder is larger than that of the sliding cylinder, and a receiving cavity is formed between the connecting cylinder and the base 1-1. This receiving cavity is used to place the control component. At the same time, a corresponding power supply is arranged on the base 1-1 to supply power to the control component and the electromagnet 2-2.

[0038] Among them, when the ejection cylinder is clamped with the elastic buckle 2-3, there can be a proper gap at one end of the ejection cylinder close to the connecting cylinder. The purpose of this gap is to prevent the movable end of the elastic buckle 2-3 from not being able to be clamped with the inner wall of the ejection cylinder due to manufacturing errors.

[0039] For a further optimized solution, the ejection cylinder includes a sleeve 3-2 sleeved on the sliding cylinder. A spring 3-1 is arranged inside the sleeve 3-2. The spring 3-1 is located at one end of the sliding cylinder away from the connecting cylinder. Both ends of the spring 3-1 are in contact with the end of the sliding cylinder and the inner wall of the sleeve 3-2 respectively. A clamping groove adapted to the movable end of the elastic buckle 2-3 is opened on the inner wall of the sleeve 3-2. When the sleeve 3-2 is clamped with the elastic buckle 2-3, the spring 3-1 is in a compressed state. When the sleeve 3-2 is disengaged from the elastic buckle 2-3, the spring 3-1 resets and provides power to the sleeve 3-2. The spring 3-1 releases elastic potential energy and transmits the force to the door through the sleeve 3-2, so as to achieve the purpose of covering the door.

[0040] Among them, the clamping groove can be a rectangular groove, an arc groove, a square groove, etc. In this technical solution, the rectangular groove is taken as an example. The clamping groove can be set in different shapes, but it should be able to achieve normal clamping with the elastic buckle 2-3.

[0041] Among them, the end of the sleeve 3-2 in contact with the door is preferably made of a flexible material or the end surface is covered with a flexible material. This material has a certain hardness to achieve the pushing of the door while reducing the noise when contacting the door.

[0042] In an embodiment of the present invention, the spring 3-1 is directly arranged inside the sleeve 3-2, and both ends of the spring 3-1 are only in contact and extrusion with the sliding cylinder and the inner wall of the sleeve 3-2.

[0043] In one embodiment of the present invention, the spring 3-1 is fixedly connected to the inner wall of the sleeve 3-2 and / or the end of the connecting cylinder. In both of the above two connection methods, the connection and fixation of the spring 3-1 to the inner wall of the sleeve 3-2 and / or the connecting cylinder can be achieved.

[0044] In a further optimized solution, at least one guiding groove is provided on the inner wall of the sleeve 3-2. The elastic buckle 2-3 is located in one of the guiding grooves, and the clamping groove is provided in the guiding groove that matches the elastic buckle 2-3. A protrusion is fixedly connected to the outer wall of the sliding cylinder away from the end face of the connecting cylinder, and the protrusion is located in the guiding groove. The guiding groove is used for the sleeve 3-2 to move along the outer wall of the sliding cylinder. It can be understood that one end of the sleeve 3-2 close to the connecting cylinder is a closed structure, that is, there is no guiding groove in this part of the structure. This part cooperates with the protrusion to limit the sleeve 3-2 so that it cannot leave the sliding cylinder.

[0045] Preferably, the guiding grooves are preferably provided in two, and the two guiding grooves are arranged oppositely.

[0046] In a further optimized solution, the control member includes a controller 2-1 fixedly connected to the inner wall of the connecting cylinder. The controller 2-1 is electrically connected to a temperature sensor or a temperature display, and the controller 2-1 is connected to the electromagnet 2-2 through a connecting wire. The controller 2-1 controls the operation of the electromagnet 2-2 according to the temperature fed back by the temperature sensor or the temperature display, so as to realize the ejection of the sleeve 3-2.

[0047] In one embodiment of the present invention, as Figure 5 shown, the temperature display is an indoor thermometer. The indoor temperature measured by the indoor thermometer is fed back to the Bluetooth module, and the Bluetooth module feeds back the temperature to the controller 2-1. The controller 2-1 judges whether the temperature meets the door closing requirement. When the temperature meets the door closing requirement, the controller 2-1 controls the relay to be energized, so that the electromagnet 2-2 is energized to generate a magnetic force to adsorb the sleeve 3-2, thereby realizing the ejection of the sleeve 3-2.

[0048] In one embodiment of the present invention, as Figure 6 shown, the temperature sensor is a self-thermometer (not shown in the figure) fixed to the outer wall of the connecting cylinder. The indoor temperature measured by the self-thermometer is fed back to the Bluetooth module, and the Bluetooth module feeds back the temperature to the controller 2-1. The controller 2-1 judges whether the temperature meets the door closing requirement. When the temperature meets the door closing requirement, the controller 2-1 controls the relay to be energized, so that the electromagnet 2-2 is energized to generate a magnetic force to adsorb the sleeve 3-2, thereby realizing the ejection of the sleeve 3-2.

[0049] The above two ways of setting can detect the indoor temperature and the temperature at the door. One of them or both can be selected according to actual needs. When both are available, one of them can be selected according to actual needs.

[0050] Based on the above two embodiments, the controller 2-1 has the function of controlling the energization time of the relay. For example, the controller 2-1 controls the relay to be energized for a short time such as 3 s, 4 s, 5 s, etc., and then controls the relay to be de-energized. In this setting, the next engagement of the elastic buckle 2-3 with the sleeve 3-2 can be ensured in a short time.

[0051] In a further optimized solution, a battery box 1-3 is fixedly connected to the side of the base 1-1 away from the wall. A battery 1-4 is arranged in the battery box 1-3. The battery 1-4 is connected to the electromagnet 2-2 through a wire, and the battery 1-4 is connected to the controller 2-1 through a connecting wire. The battery box 1-3 is used for containing the battery 1-4. Among them, the battery 1-4 is a dry battery, which is small in volume and low in energy consumption.

[0052] In a further optimized solution, at least one pair of matching mounting holes are provided on the connecting cylinder and the base 1-1. Fixing members are arranged in the mounting holes. The connecting cylinder and the base 1-1 are fixed to the wall through the mounting holes and the fixing members. The mounting holes are used for passing through the fixing members so that the connecting cylinder is fixed on the base 1-1, and the base 1-1 is fixed on the wall.

[0053] Among them, the fixing member can be one of a screw, a bolt, etc., as long as the fixing of the base 1-1 is realized.

[0054] Preferably, four mounting holes are provided, and they are axially distributed on the base 1-1.

[0055] Specifically, when assembling the concealed door device, the battery 1-4 and the battery box 1-3 are installed in the base 1-1. Then, the controller 2-1 and the electromagnet 2-2 are installed in the housing 1-2 and the wires are connected. Then, the elastic buckle 2-3 is installed on the housing 1-2 with the fixing screw 2-4. The assembled housing 1-2 assembly is sleeved on the base 1-1, and the two are installed on the wall with screws or bolts. Finally, the spring 3-1 is placed at the bottom of the hole of the sleeve 3-2. It is optional to connect the spring 3-1 or not, and finally the housing 1-2 is inserted into the sleeve 3-2.

[0056] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0057] The embodiments described above are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention.
