Description

Technical Field

[0001] The present application relates to the technical field of fire doors, and in particular to a scalding-proof fire door. Background Art

[0002] Fire doors, as a type of door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time, are fire-resistant partitions with a certain degree of fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.

[0003] For example, a fire door proposed in announcement number CN212317792U cools down the door body by manually opening the closed door while providing some fire escape items. However, people in a fire often cannot take correct measures if they are not familiar with such doors. It is difficult to open the door body to escape under the high temperature. At the same time, closed doors that can be opened at any time often attract some children to open and play.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a scald-proof fireproof door to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve its technical problem is to include: a door panel, a receiving groove is provided on the door panel, and a water outlet nozzle is installed on one side of the receiving groove; a baffle is rotatably arranged on the outside of the receiving groove, and automatically pops open in case of fire, so as to open the receiving groove to provide water and escape items; a water cooling pipe is arranged inside the door panel, a part of which is connected to the water outlet nozzle, so as to cool the door panel; a fire detection device is arranged on both sides of the door panel, so as to detect abnormal information in the house; an automatic control valve is arranged at the water inlet end of the water cooling pipe, so as to control the circulation of the water cooling pipe; a control assembly is arranged on one side of the door panel, so as to receive and analyze the abnormal information of the fire detection device and send a signal to the automatic control valve.

[0007] In some embodiments, a bracket is installed on one side of the baffle for hanging firefighting items such as towels.

[0008] In some embodiments, a bimetallic strip is installed in the receiving groove. At room temperature, one end of the bimetallic strip is fixed to the top of the receiving groove, and the other end abuts against one side of the receiving groove to lock the bracket.

[0009] In some embodiments, the bimetallic strip automatically bends in another direction at high temperature, the bracket is released from the locking of the bimetallic strip, and the baffle automatically expands outward.

[0010] In some embodiments, the bimetallic strip is composed of two metals, and the thermal expansion coefficient of the metal on the side facing the water outlet nozzle is greater than the thermal expansion coefficient of the metal on the other side.

[0011] In some embodiments, the baffle on the door panel is hinged to the door panel via a hinge.

[0012] In some embodiments, handles are installed on both sides of the door panel, a mechanical lock is installed on one side of the door panel, and the handles are connected to the mechanical lock.

[0013] The beneficial effects of the present application are as follows: abnormal information detected by the fire detection device is analyzed and processed by the control assembly and transmitted to the automatic control valve, which can quickly respond when a fire occurs, allowing the water-cooling pipe to cool the door body. At the same time, at high temperatures, the bimetallic strip will pop open and release the bracket, and the baffle can automatically pop open, providing panicked refugees with clear survival items and water sources, effectively increasing the probability of escape. At the same time, the baffle, which is locked under normal circumstances, can also effectively prevent children from opening it, affecting the internal structure and use during fire.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0020] In the examples of this application, please refer to Figure 1-3 As shown, the present application provides a scalding-proof fire door, which mainly includes: a door panel 1, a receiving groove 11 is provided on the door panel 1, and a water outlet nozzle 12 is installed on one side of the receiving groove 11; a baffle 2, which is rotatably arranged on the outside of the receiving groove 11 and automatically pops open in case of fire, for opening the receiving groove 11 to provide water and escape items; a water-cooling pipe 3, which is arranged inside the door panel 1, a part of which is connected to the water outlet nozzle 12, for cooling the door panel 1; a fire detection device 4, which is arranged on both sides of the door panel 1, for detecting abnormal information in the house; an automatic control valve 5, which is arranged at the water inlet end of the water-cooling pipe 3, for controlling the circulation of the water-cooling pipe 3; a control assembly 6, which is arranged on one side of the door panel 1, for receiving and analyzing the abnormal information of the fire detection device 4 and sending a signal to the automatic control valve 5.

[0021] Specifically, when a fire occurs, the fire detection device 4 will detect sufficient abnormal information and then send the abnormal information to the control assembly 6, which will then analyze and respond. When it is confirmed that there may be a fire, the control assembly 6 will send a signal to the automatic control valve 5, and the automatic control valve 5 will pass water through the water-cooling pipe 3 to cool the door body. At the same time, the baffle 2 will automatically pop out and open the receiving groove 11 to provide water and escape items.

[0022] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0023] Reference Figure 3 As shown, in order to lock the baffle 2 in a normal state and prevent the baffle 2 from being opened under unnecessary circumstances due to external force, thereby affecting subsequent use, a bracket 21 is installed on one side of the baffle 2 for hanging fire-fighting items such as towels.

[0024] Specifically, a bimetallic strip 13 is installed in the receiving groove 11. At room temperature, one end of the bimetallic strip 13 is fixed to the top of the receiving groove 11, and the other end abuts against one side of the receiving groove 11 to lock the bracket 21. The bimetallic strip 13 is used to lock and quickly respond to fire, and can quickly respond to the temperature of the fire. At the same time, no electricity is required, which prevents the possibility of the circuit being completely burned out. The escape items in the receiving groove 11 can provide additional escape possibilities.

[0025] More specifically, in order to enable the bimetallic strip 13 to automatically unlock the bracket 21 at high temperatures and allow the bracket 21 to automatically fall under the action of gravity, the bimetallic strip 13 will automatically bend in another direction at high temperatures, the bracket 21 will be released from the lock of the bimetallic strip 13, and the baffle 2 will automatically expand outward.

[0026] As an explanation, the bimetallic strip 13 is composed of two metals. The thermal expansion coefficient of the metal on the side facing the water outlet nozzle 12 is greater than the thermal expansion coefficient of the metal on the other side. At normal temperature, the metal on one side of the bimetallic strip 13 will remain in a contracted state, causing the bimetallic strip 13 to lean to one side. At high temperature, the metal with a larger expansion coefficient will begin to expand, causing the bimetallic strip 13 to lean to the other side. At this time, the bracket 21 will slide over the bimetallic strip 13 and fall outward.

[0027] Preferably, in order to prevent the door panel 1 from falling when it falls, the upper baffle 2 of the door panel 1 is hinged to the door panel 1 through a hinge 22.

[0028] Reference Figure 1 As shown, in order to enable the door panel 1 to be opened and used normally, handles 14 are installed on both sides of the door panel 1, and a mechanical lock 15 is installed on one side of the door panel 1, and the handles 14 are connected to the mechanical lock 15.

[0029] Thus far, various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the various embodiments of the present application.
