Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door and window air intake accessory and a door and window frame structure. Background Technology

[0002] Sealing strips are often used during the installation of door and window frames. Sealing strips are accessories installed between the glass and the frame. They effectively prevent wind, rain, and other weather elements from damaging the interior, ensuring a dry and comfortable indoor environment.

[0003] When doors and windows are closed, the sealing strips can fit tightly against the door and window frames and glass, forming an effective sealing barrier to prevent wind, rain, dust, insects and other pollutants from entering the room.

[0004] However, even after installing sealing strips, existing door and window frames can still provide a certain degree of sealing. But when encountering strong winds and rain, the relatively sealed interior space of the doors and windows can lead to a decrease in the air pressure inside due to changes in external air pressure. This creates a negative pressure inside the doors and windows, causing rainwater to flow back into the room through the drainage holes under the influence of atmospheric pressure. Utility Model Content

[0005] One objective of this invention is to solve the problem that, after the installation of sealing strips on existing door and window frames, rainwater from the outside can backflow into the room through the drainage holes under air pressure.

[0006] Specifically, embodiments of this application provide a door / window air intake accessory, comprising:

[0007] The main body has an air passage running through it, and one side surface of the main body is used to adhere to the glass.

[0008] The mounting component is located on the side opposite to the side of the main body that is in contact with the glass. The mounting component cooperates with the door and window frame profile groove for installing the sealing strip, thereby fixing the mounting component inside the door and window frame profile groove.

[0009] Furthermore, the number of airways is multiple.

[0010] Furthermore, the side of the main body perpendicular to the air passage direction is configured as an inclined surface adapted to the sealing strip.

[0011] Furthermore, a slanted baffle is provided at the port of the airway to prevent mosquitoes from entering.

[0012] This utility model also provides a door and window frame structure, including:

[0013] Door and window frames are used to fix glass, and the door and window frames have door and window frame profile grooves on the outdoor side;

[0014] A sealing strip, which engages in a groove in each of the door and window frame profiles, is disposed on the door and window frame profile and has at least one notch; and

[0015] At least one of the aforementioned door and window air intake fittings is installed at the notch, the mounting component is connected to the groove of the door and window frame profile, and the outer surface of the main body is in contact with the glass.

[0016] Furthermore, a sealant is applied between the air intake fitting for the door and window and the sealing strip.

[0017] Furthermore, the door and window frame includes multiple door and window frame profiles that together form a rectangular frame, and the door and window air intake fittings are only installed on the door and window frame profiles that are horizontally set and located at the upper part of the vertical direction.

[0018] Furthermore, the main body is provided with a bevel on one side perpendicular to the air duct direction, which is adapted to the sealing strip, and the side of the door and window frame air inlet fitting with the bevel is exposed outside the door and window frame profile.

[0019] Furthermore, a slanted baffle for preventing mosquitoes is provided at the port of the air duct, and the slanted baffle is exposed outside the door and window frame profile.

[0020] The beneficial effects of this utility model are:

[0021] 1. Because the air intake fitting of this utility model has a through-hole, indoor and outdoor air can be exchanged through the air duct, achieving a balance between indoor and outdoor air pressure. This prevents rainwater from flowing back into the room through the drain hole due to low indoor air pressure.

[0022] 2. By applying sealant, the air intake fittings and sealing strips of doors and windows are integrated into a single unit, preventing external rainwater from entering the door and window frame profiles and interior through the gaps between the air intake fittings and sealing strips.

[0023] 3. By exposing the side with the inclined baffle to the outside of the door and window frame profile, outdoor mosquitoes are prevented from entering the airway and causing airway blockage. Attached Figure Description

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0030] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] like Figure 1 As shown, the door and window air intake accessory 100 of this utility model includes a main body 1 and an mounting component 2. The main body 1 has an air passage 4 extending through it, and its outer surface can be fitted with glass 8. Here, glass 8 refers to the door and window glass installed within the window frame. The mounting component 2 is located on the side opposite to the side of the main body 1 that is fitted with glass 8. The mounting component 2 cooperates with the groove 9 of the door and window frame profile 7 used for installing the sealing strip 6, fixing the mounting component 2 within the groove 9.

[0033] Because the door and window air intake fitting 100 of this utility model is provided with a through air duct 4, indoor and outdoor air can be exchanged through the air duct 4 to achieve a balance of indoor and outdoor air pressure. This door and window air intake fitting that can connect with the outside can prevent rainwater from flowing back into the room through the drain hole due to low indoor air pressure.

[0034] In one embodiment, the number of air ducts 4 is one or more. When the door and window frame is large, a larger multi-air duct door and window air intake fitting 100 can be installed. When the door and window frame is small, a smaller single-air duct door and window air intake fitting 100 can be used. By setting the number of air ducts 4 to one or more, the applicability of the door and window air intake fitting 100 of this utility model is broadened.

[0035] In one embodiment of the door and window air intake accessory 100 of this utility model, the main body 1 has a bevel 5 on one side perpendicular to the air duct 4, which is adapted to the sealing strip 6. After the door and window air intake accessory 100 is installed, it can better cooperate with the sealing strip 6, enhancing the overall integrity of the installed accessory 100. The specific shape of the bevel can be determined according to the shape of the sealing strip 6. As long as it ensures a tight fit between the door and window air intake accessory 100 and the sealing strip 6, and provides a better overall fit after installation, it falls within the protection scope of this utility model.

[0036] In one embodiment, a beveled baffle 3 for preventing mosquitoes is provided at the port of the air duct 4. By providing the beveled baffle 3, after installing the door and window air intake accessory 100 of this utility model, indoor and outdoor air exchange is ensured while preventing mosquitoes from entering the room from the outside through the air duct 4. In one embodiment, such as Figure 1 As shown, the inclined baffle 3 can be installed at one port of the airway 4. In other embodiments, the inclined baffle 3 can also be installed at both ports of the airway 4. Alternatively, the inclined baffle 3 can be configured as an inclined plate with the same length as the airway 4, and the inclined plate can be placed in the airway 4.

[0037] To improve the blocking effect of the angled baffle on mosquitoes, it can also be designed as a mesh or cross shape.

[0038] To facilitate cleaning of the angled baffle and airway, the angled baffle can be made detachable. When the airway is heavily clogged with insects or the angled baffle is covered in dust due to prolonged use, it can be removed for cleaning and then reinstalled on the airway.

[0039] In other embodiments, in order to improve the sealing performance of the door and window air intake fitting 100 after the present invention is installed, a sealing gasket can be provided on the side of the door and window air intake fitting that is in contact with the glass to prevent rainwater from seeping into the room from the contact point between the door and window air intake fitting 100 and the glass 8.

[0040] This utility model also provides a door and window frame structure including the aforementioned door and window air intake fitting 100, comprising the door and window air intake fitting 100, door and window frame profiles 7, and sealing strips 6. The door and window frame profiles 7 are used to fix the glass 8. There are four door and window frame profiles 7 arranged in a square. The exterior side of each door and window frame profile 7 has a groove 9. The sealing strip 6 engages in the groove 9 of each door and window frame profile 7. When the sealing strip 6 is installed on the door and window frame profile 7, at least one notch is left, and the door and window air intake fitting 100 of this utility model is installed at the notch. During installation, the mounting component 2 is connected to the groove 9 of the door and window frame profile 7. Simultaneously, the outer surface of the main body 1 is pressed against the glass 8. Under the clamping action of the door and window frame profiles 7, the door and window air intake fitting 100 and the glass 8 are ensured to fit more tightly.

[0041] By installing the door and window air intake accessory 100 of this utility model at the notch of the rubber strip and fixing it at the groove 9 of the door and window frame profile 7, and attaching the main body 1 to the glass 8, the outside air exchanges with the indoor air through the air passage 4, balances the indoor and outdoor air pressure, and prevents outside rainwater from flowing back into the room through the drainage hole under the action of air pressure.

[0042] In one embodiment, sealant is applied between the door / window air intake fitting 100 and the sealing strip 6. By applying the sealant, the door / window air intake fitting 100 and the sealing strip 6 are bonded together as a whole, preventing external rainwater and other substances from entering the room through the gap between the door / window air intake fitting 100 and the sealing strip 6.

[0043] Furthermore, the window and door air intake fitting 100 is only installed on the horizontally positioned upper part of the window and door frame profile 7 in the vertical direction. Similarly, the sealing strip 6 only forms a notch at the point where it mates with the window and door air intake fitting 100. Since rainwater falls from top to bottom, installation on the horizontally positioned upper part of the window and door frame profile 7 in the vertical direction prevents rainwater from entering the room through the air duct 4. In other embodiments, the window and door air intake fitting 100 can also be installed on each window and door frame profile 7, with a smaller air duct 4 aperture, ensuring sufficient exchange of indoor and outdoor air while preventing rainwater from entering the room through the air duct 4.

[0044] In one embodiment, the side of the door / window frame air intake fitting with the bevel 5 is exposed outside the door / window frame profile 7. By exposing the side with the bevel outside the door / window frame profile 7, the door / window air intake fitting 100 cooperates with the sealing strip 6 exposed to the outside, enhancing the overall integrity of the door / window air intake fitting 100 and the sealing strip 6 after they are combined.

[0045] In one embodiment, the beveled baffle 3 is exposed outside the door / window frame profile 7. By exposing the beveled baffle outside the door / window frame profile 7, outdoor mosquitoes are prevented from entering the airway 4 and causing blockage of the airway 4.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
