[0023] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0024] Example 1 like Figures 1-4 As shown, a ventilated security door includes a door body 1, a ventilation zone 2 disposed on the door body 1, and ventilation holes 21 distributed on the ventilation zone 2 penetrating the door body 1; it also includes: an installation area 3, which is a recessed structure and is disposed on the back side of the ventilation zone 2; a screen assembly 4, which is detachably disposed in the installation area 3, including: a window body 41; a screen 42 disposed in the window body 41; and a sealing element 43 disposed on the outside of the window body 41; the area of ​​the ventilation zone 2 is less than or equal to the area of ​​the screen 42; the sum of the width of the window body 41 and the width of the sealing element 43 is slightly less than the width of the installation area 3, so that the window body 41 can be locked in the installation area 3.

[0025] The door is hinged to the door frame 01; the door is equipped with a locking mechanism to facilitate closing or opening the door, which is one of the basic functions of a ventilated security door; the locking mechanism used is an existing product and is not an innovation of this application, and the specific model is not described here; the installation, fixing and use of the locking mechanism are all existing technologies and will not be described in detail.

[0026] The ventilation zone is located on the door. To maintain good ventilation, the ventilation zone should be located above half the height of the door. The area of ​​the ventilation zone is 0.2-0.4 times the area of ​​the door. Ventilation holes are evenly distributed in the ventilation zone. The ventilation needs of the door can be met through the ventilation holes. There is no need to open the door when ventilating, which improves security.

[0027] A second sealing layer can be installed in the installation area to make the screen installation more secure and tight.

[0028] The mesh screen can keep out dust and other debris, preventing them from entering the room through the ventilation holes.

[0029] The first and second sealing elements are made of the existing window sealing strip material, which is slightly softer and allows for a better sealing effect between the window frame and the installation area, preventing dust and other debris from entering.

[0030] The installation area has a recessed structure, meaning it is recessed from the back of the door towards the ventilation hole. The depth of the installation area is less than the thickness of the door, so that the ventilation area has a certain thickness and the ventilation hole area has a certain strength.

[0031] The window frame of the screen assembly is used to install and fix the screen. It is installed in a detachable manner, so the screen can be removed for cleaning when it is dirty, dried and then reinstalled in the installation area, improving the convenience of use.

[0032] When in use, simply close and lock the door. Air enters the room through the ventilation holes, which helps with air circulation. When the weather is not hot, ventilation through the ventilation holes is sufficient, eliminating the need for air conditioning or fans, thus saving energy and protecting the environment. After a period of use, if a lot of dust and debris adheres to the screen, the window can be removed from one side of the installation area, washed, dried, and then reinstalled. The operation is simple and quick.

[0033] Example 2 This ventilated security door also has the following technical features: like Figure 1 , Figure 5 As shown, the screen window assembly 4 also includes a pull hole 44, which is provided on the window body 41; when the pull hole 44 is pulled outward by an external force, the window body 41 can be pulled outward from the installation area 3.

[0034] like Figure 3 , Figure 4 As shown, the ventilated security door also includes: a closed door 5, which is hinged to one side of the installation area 3; the closed door 5 is provided with a locking mechanism 51 that can lock it to the door body 1.

[0035] like Figure 3 , Figure 4 , Figure 6 As shown, a pull ring 52 is provided on the side of the closed door 5 that is not facing the screen 42; when the pull ring 52 is pulled outward by an external force, the closed door 5 can be opened.

[0036] like Figure 6 The pull ring 52 shown is rotatably connected to the locking mechanism 51. When in use, the pull ring 52 can be rotated outward relative to the locking mechanism 51 and pulled outward, and can be retracted when not in use.

[0037] The pull hole facilitates the removal of the screen window assembly. A rope can be tied to the pull hole, and when the screen window assembly needs to be removed, simply pull the rope outward to pull the window out and remove it; during installation, simply push the window into the installation area.

[0038] The enclosed door can be closed when ventilation is not required, and it also serves to protect privacy. The locking mechanism on the enclosed door is an existing product and is not an innovation of this application. The specific model will not be described here. The installation, fixing, and use of the locking mechanism are all existing technologies and will not be described in detail.

[0039] The mechanical knob of the locking mechanism of the closed door can be a circular structure with a handle inside for gripping and pulling. It can be rotated outward to extend and open the convenient door. When the handle is not needed, it can be folded into the circular shape.

[0040] Example 3 This ventilated security door also has the following technical features: like Figure 5 As shown, mesh 42 is made of diamond mesh.

[0041] like Figure 1 , Figure 4 As shown, the orthographic projection of the ventilation hole 21 toward the screen 42 is all on the screen 42 within the area enclosed by the window 41.

[0042] The mesh is made of existing diamond mesh material, which has high strength and combines anti-theft and ventilation features.

[0043] Ventilation holes are for ventilation; therefore, the area projected by the ventilation holes should be within the screen so that air passing through the ventilation holes can enter the room after passing through the screen.

[0044] It should be noted that, in this document, relational terms such as "second" and "etc." are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
