Description

Technical Field

[0001] This utility model relates to the technical field of door and window accessories, and in particular to a pressure-boosting floor drain for doors and windows. Background Technology

[0002] Doors and windows are crucial components of buildings, and their performance significantly impacts the indoor environment. To prevent water accumulation inside doors and windows during rain, drainage systems must be installed.

[0003] A search revealed Chinese patent publication number CN214062797U, which discloses a drainage structure and door / window drainage system, belonging to the field of door / window drainage technology. It is designed to solve technical problems such as water overflowing into the room due to untimely drainage and rusting of door / window hardware from immersion. The drainage structure includes an outer windshield, an inner shell, and a windshield plate. The outer windshield is mounted on a profile, and the inner shell is connected to the outer windshield to form a receiving groove. The windshield plate is rotatably connected to the inner shell, and a boss is provided at the bottom of the inner shell. The windshield plate can abut against the side wall of the boss to close the receiving groove.

[0004] Existing door and window drainage systems are generally designed with water inlets, water outlets, and air inlets. However, rainwater may also enter through the air inlet, and when the wind force entering through the air inlet is strong, it will cause the water outlet structure to close, thus failing to complete the water leakage function.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a pressure-boosting floor drain for doors and windows, making it more valuable for industrial use. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pressure-boosting floor drain for doors and windows.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pressure-boosting floor drain for doors and windows includes a main body, with an inlet on one side of the top of the main body and an outlet on one side of the bottom of the main body.

[0009] The water outlet is located at the bottom of the main structure on the side away from the water inlet, and several air inlets are provided on the side of the main structure above the water outlet.

[0010] An inlet cavity and a valve plate movable cavity are sequentially provided on the side away from the inlet in the main structure below the inlet, and a valve plate is installed between the inlet cavity and the valve plate movable cavity;

[0011] A vertical air guide plate is installed on the top of the valve plate movable cavity on the side facing the water outlet. A vertical plate slope is installed at the bottom of the vertical air guide plate, which is inclined downwards towards the water outlet. A waterproof inclined plate is installed in the main structure below the air inlet, which is inclined upwards. An air guide cavity is formed between the waterproof inclined plate and the vertical air guide plate.

[0012] As a further improvement of this utility model, an annular rib is provided on the main structure outside the water inlet, and a locking element is provided inside the annular rib.

[0013] As a further improvement of this utility model, a water inlet grille is installed on the inner side of the water inlet near the top.

[0014] As a further improvement of this utility model, a first inlet ramp is provided at the bottom of the inlet cavity, which is inclined toward the inlet side facing downward.

[0015] As a further improvement of this utility model, the top of the valve plate is movably hinged to the valve plate mounting block on the top side of the valve plate movable cavity.

[0016] As a further improvement of this utility model, a valve plate ramp inclined towards the lower water inlet side is provided at the bottom of the valve plate, and a second water inlet ramp parallel to the above-mentioned valve plate ramp is provided in the valve plate movable cavity below the valve plate ramp.

[0017] As a further improvement of this utility model, a sealing gasket is installed between the valve plate slope and the second inlet slope.

[0018] As a further improvement of this utility model, an upward-sloping air guide is provided in the main body of the structure on one side of the top of the air inlet.

[0019] As a further improvement of this utility model, an arc-shaped inner wall for water outlet is provided in the main structure on both sides of the water outlet.

[0020] By means of the above solution, this utility model has at least the following advantages:

[0021] This utility model features a waterproof inclined plate at the air inlet, which can greatly reduce the possibility of rainwater entering. Even if some rainwater is carried in by the inlet, it can flow through the air guide vertical plate and the inclined plate to the outlet below.

[0022] When the wind entering from the air inlet is relatively strong, it is first guided by the air guide slope and waterproof inclined plate at the air inlet, and then guided a second time by the air guide vertical plate, vertical plate slope and waterproof inclined plate, so that most of the air will not enter the side near the water inlet, thus avoiding the situation of the water outlet structure being shut down.

[0023] When the airflow enters through the air inlet and exits, the vortex drives the internal air pressure to flow outward, which accelerates the outward discharge of the internal water.

[0024] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the following are the preferred embodiments of this utility model and are described in detail with reference to the accompanying drawings.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] The first embodiment of this utility model:

[0035] like Figures 1-2 As shown in the figure, a pressure-boosting floor drain for doors and windows in this embodiment mainly includes a main body 1, which is designed with a water inlet 3, an air inlet 5 and a water outlet 19.

[0036] The water inlet 3 is designed on the top side of the main structure 1, the water outlet 19 is designed on the bottom of the main structure 1 on the side away from the water inlet 3, and the air inlet 5 is designed on the side of the main structure 1 above the water outlet 19. In actual installation, the water inlet 3 is installed in the water accumulation area of ​​the door and window, and the air inlet 5 and the water outlet 19 are connected to the outside.

[0037] Among them, there are several air inlets 5, and they work independently of each other.

[0038] like Figure 1 As shown, an annular rib 2 is provided on the main body 1 outside the water inlet 3, and a locking component 4 is provided inside the annular rib 2. The locking component 4 can be a bolt or the like. The main body 1 is installed at the door or window through the locking component 4.

[0039] like Figure 2 As shown, a water inlet grille 6 is installed on the inner side of the water inlet 3 near the top. This water inlet grille 6 can effectively prevent debris from falling into the water inlet 3.

[0040] like Figure 3 As shown, the internal structure of the main body 1:

[0041] The drain device in this embodiment includes multiple cavity structures: a water inlet cavity 7 connected to the water inlet 3, a valve plate movable cavity 13 for the valve plate 10 to move, and an air guide cavity 18 connected to the air inlet 5.

[0042] Specifically, an inlet cavity 7 and a valve plate movable cavity 13 are sequentially provided on the side away from the inlet 3 within the main body 1 below the inlet 3. A valve plate 10 is installed between the inlet cavity 7 and the valve plate movable cavity 13. The top of the valve plate 10 is movably hinged to the valve plate mounting block 9 on the top side inside the valve plate movable cavity 13.

[0043] A first inlet ramp 8 is provided at the bottom of the inlet chamber 7, which is inclined towards the inlet 3 facing downward, so that the water 21 entering the inlet chamber 7 through the inlet 3 can flow conveniently to the lower valve plate movable chamber 13 and the subsequent outlet 19.

[0044] The structure of valve plate 10 is similar to that of floor drain check valve, etc. Valve plate 10 opens outward under the impact of water flow, and closes automatically by gravity or elastic force when there is no water (a tension spring can be designed at valve plate 10 to keep valve plate 10 in a closed state when it is not working normally).

[0045] A valve plate ramp 11, inclined downwards towards the water inlet 3, is provided at the bottom of the valve plate 10. A second water inlet ramp 12, parallel to the valve plate ramp 11, is provided within the valve plate movable cavity 13 below the ramp 11. A sealing gasket is installed between the valve plate ramp 11 and the second water inlet ramp 12. The sealing gasket forms a sealing mating surface between the valve plate ramp 11 and the lower second water inlet ramp 12, blocking the airflow and water flow channels when closed.

[0046] The air inlet 5 of the air duct is a constricted trumpet shape, wider on the outside and narrower on the inside. External air (i.e., air intake 22) is compressed and enters the interior of the air duct after passing through the air inlet 5. A guide and reflection structure (such as guide ramp 16, guide vertical plate 14 and vertical plate ramp 15) is set on the inner wall of the air duct so that the airflow is reflected and discharged.

[0047] Specifically, an upward-sloping air guide ramp 16 is provided inside the main structure 1 on one side of the top of the air inlet 5, and an upward-sloping waterproof ramp 17 is provided inside the main structure 1 below the air inlet 5, forming a converging trumpet shape that is wider on the outside and narrower on the inside, as described above. An air guide vertical plate 14 is provided at the top of the valve plate movable cavity 13 on the side facing the water outlet 19, and an inclined vertical plate ramp 15 facing the downward water outlet 19 is provided at the bottom of the air guide vertical plate 14. An air guide cavity 18 is formed between the waterproof ramp 17 and the air guide vertical plate 14, which is a flow guiding and reflecting structure as described above.

[0048] In addition, arc-shaped inner walls 20 are provided in the main body 1 on both sides of the outlet 19 to facilitate the discharge of water 21 and air 22 from the outlet 19.

[0049] like Figure 4 As shown, the working principle of this embodiment is briefly described as follows:

[0050] Water accumulated in the water accumulation area inside the doors and windows (i.e., water inlet 21) enters the water inlet cavity 7 below through the water inlet 3. Then, the valve plate 10 is opened outward by the impact force of the water flow, and then continues to flow into the valve plate movable cavity 13. Under the action of the vertical plate slope 15 and the water outlet arc-shaped inner wall 20 on the side of the outlet 19 near the water inlet 3, it flows into the outlet 19 and is discharged. When external air (i.e., air inlet 22) enters the air inlet 5, due to the contraction funnel-shaped structure composed of the air guide slope 16 and the waterproof slope 17, the air inlet 22 is compressed and enters the air guide cavity 18. Then, through the action of the air guide vertical plate 14, the vertical plate slope 15 and the waterproof slope 17, the air inlet 22 reaches the outlet 19. When the air inlet 22 flows out, the vortex drives the internal air pressure to flow outward, which accelerates the discharge of the internal water flow (i.e., water inlet 21).

[0051] The flow directions of water inlet 21 and air inlet 22 are as follows: Figure 4 The middle arrow indicates.

[0052] The internal cavity of the main structure 1 is connected at both ends to the water accumulation area inside the door and window opening sash and the outdoor environment, respectively. The water outlet (i.e., water outlet 19) is lower than the air inlet (i.e., air inlet 5) of the air duct, forming a natural drainage of water flowing downhill. The outer edge of the air inlet 5 of the air duct is provided with a rainproof eave (i.e., waterproof sloping plate 17) to prevent rainwater from directly entering.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
