It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1 to 3, an embodiment of the present invention provides a ventilation sunshade curtain, which includes an air intake side rail 1, an air exhaust side rail 2, a driving system 3, a curtain sheet 4, a curtain bottom sheet 5 and a fan 6; the air inlet side guide rail 1 and the air outlet side guide rail 2 are respectively fixedly arranged on two sides, the air inlet side guide rail 1 and the air outlet side guide rail 2 are internally provided with cavities 9 extending along the axial direction, the cavities 9 on the air inlet side guide rail 1 are communicated with the opening of the air inlet side guide rail 1, and the cavities 9 on the air outlet side guide rail 2 are communicated with the opening of the air outlet side guide rail 2; an air inlet port 7 communicated with a cavity 9 of the air inlet side guide rail 1 is arranged on the air inlet side guide rail 1, and an air outlet port 8 communicated with the cavity 9 of the air outlet side guide rail 2 is arranged on the outdoor side of the air outlet side guide rail 2; the driving system 3 is arranged between the tops of the two guide rails; the plurality of curtain sheets 4 are connected up and down one by one to form a curtain mat, and the top of the curtain mat is connected with the driving system 3; the inside of each curtain sheet 4 is hollow, the two ends of each curtain sheet 4 are respectively provided with a seal head 10 communicated with the inside of the curtain sheet 4, the two ends of each curtain sheet 4 are respectively connected with the air inlet side guide rail 1 and the air outlet side guide rail 2 in a sliding way, the seal heads 10 at the two ends are respectively arranged in the air inlet side guide rail 1 and the air outlet side guide rail 2, the seal heads 10 at one end are communicated with the cavity 9 of the air inlet side guide rail, and the seal heads 10 at the other end are communicated with the cavity of the air outlet side guide rail 2; the curtain bottom sheet 5 is connected to the bottom of the curtain mat; the fan 6 is connected to the intake port 7, and causes indoor air to flow through the intake port 7 and the inside of the curtain 4 to the exhaust port 8.
According to the invention, through the active guiding function of the fan 6, the air in the room is introduced into the air inlet side guide rail 1, flows to the air outlet side guide rail 2 through each curtain sheet 4, and finally is discharged out of the room through the air outlet 8, so that ventilation is performed. Meanwhile, as the indoor and outdoor temperature difference is generally large, the indoor air is more suitable for a human body, and the residual temperature of the indoor air is fully utilized in the process that the indoor old air is discharged out of the room through the curtain sheet 4, so that the temperature of the curtain sheet 4 is more prone to the indoor temperature, the heat interaction between the inside and the outside of the compartment is more effectively prevented, and the effect of the ecological curtain is achieved.
For the specific structure of the driving system 3, the driving system 3 preferably includes a motor (not shown) and a winding drum (not shown); the motor is in transmission connection with the winding drum, and the curtain is wound on the surface of the winding drum.
This process of flowing indoor air through the curtain sheet 4 occurs only in a state where the curtain sheet 4 is completely closed. The shutter 4 is opened and closed by rotating the winding drum by a motor, and the shutter 4 is slid and opened by the guiding action of the intake side rail 1 and the exhaust side rail 2, which is exactly the same as the conventional art. Of course, other driving schemes may be used for the driving system 3, which will not be described in detail herein.
More specifically, the air path construction tightness problem after the curtain sheet 4 is completely closed needs to be considered. Preferably, the intake side rail 1 and the exhaust side rail 2 are internally provided with a joint member 11 and an extension mechanism; the joint members 11 are respectively arranged in the cavities 9 of the air inlet side guide rail 1 and the air outlet side guide rail 2, and vent holes 16 which are in one-to-one correspondence with the curtain sheets 4 are axially arranged on one side of the joint members 11 facing the end parts of the curtain sheets 4; the extending mechanism is respectively arranged in the air inlet side guide rail 1 and the air outlet side guide rail 2, and the two connecting members 11 are respectively movably connected with the air inlet side guide rail 1 and the air outlet side guide rail 2 through the extending mechanism, so that when the curtain is closed, the curtain bottom sheet 5 triggers the extending mechanism to drive the two connecting members 11 to be connected with the end parts of each curtain sheet 4, and the vent hole 16 is communicated with the seal head 10.
In the state where the curtain sheet 4 is opened, the engaging member 11 is in a non-engaged state with the curtain sheet 4, the blower 6 is not activated, and the indoor old air is not introduced into the sun-shading product of the present invention. After the curtain sheet 4 is completely closed, the joint member 11 protrudes to be engaged with the head 10, and then an air path is constructed with the hollow curtain sheet 4. The fan 6 is then turned on to introduce the old air from the room, through the inside of the curtain 4 and out of the room. Typically, the engagement member 11 is of equal length as the shade.
Referring to fig. 4, for the specific technical solution of the extending mechanism, it is simpler to include an electromagnetic device 17 and a trigger switch (not shown), wherein the electromagnetic device 17 is respectively installed in the cavity 9 of the air intake side rail 1 and the air exhaust side rail 2, the electromagnetic device 17 of the air intake side rail 1 is connected between the cavity 9 of the air intake side rail 1 and the joint member 11, and the electromagnetic device 17 of the air exhaust side rail 2 is connected between the cavity 9 of the air exhaust side rail 2 and the joint member 11; the trigger switch is mounted on the bottoms of the intake side rail 1 and the exhaust side rail 2. When the electromagnetic device 17 is powered to extend, the engagement member 11 is driven to extend to engage the closure head 10. This structure clearly increases the complexity of the control.
Referring to fig. 2 to 3, another preferred embodiment is to use a linkage scheme with the curtain sheet 4: the extending mechanism comprises a swing rod 12 and a trigger terminal 13; the joint component 11 is rotationally connected with at least two swing rods 12, the tail parts of the swing rods 12 are rotationally connected with the air inlet side guide rail 1 or the air outlet side guide rail 2, and all the swing rods 12 are arranged in parallel to form a four-bar mechanism; the trigger terminal 13 has a pressing end 14 facing the end of the curtain sheet 5 and a swinging arm 15 facing the cavity 9; the two trigger terminals 13 are respectively connected with the air inlet side guide rail 1 and the air outlet side guide rail 2 in a rotating way, and the swinging arms 15 are connected with the corresponding swinging rods 12, so that when the end part of the curtain sheet 5 touches the pressing end 14, the trigger terminals 13 are driven to swing, and the connecting members 11 are driven to extend towards the end part of the curtain sheet 4 through the swinging arms 15.
When the curtain sheet 4 is closed, the curtain sheet 5 must move to the ends of the intake side rail 1 and the exhaust side rail 2, and at this time, the pressing end 14 of the trigger terminal 13 is touched. The linkage scheme omits the complicated electromagnetic control and is a scheme with high reliability and free from debugging.
To solve the problem of joint tightness of the seal head 10 and the joint member 11, preferably, the outer end of the seal head 10 is provided with a concave U-shaped notch, one side of the joint member 11 facing the end of the curtain sheet 4 is in a U-shaped protrusion, and the joint member 11 is embedded in the U-shaped notch of the seal head 10 in joint communication with the curtain sheet 4, so that tight fitting is ensured, and the vent hole is completely aligned with the seal head 10.
Referring to fig. 5, for the sealing problem between the hollow cavity 9 and the joint member 11 in the air path, preferably, two partition plates 18 are disposed on the side of the hollow cavity 9 of the air intake side rail 1 and the air exhaust side rail 2 facing the opening, and the partition plates 18 are suspended relatively; limiting edges 19 matched with the partition plates 18 are arranged on two sides of the joint member 11, the joint member 11 stretches out and draws back at the suspended position between the partition plates 18, and the limiting edges 19 are attached to and sealed with the partition plates 18 when the joint member stretches out. Further, a sealing rubber strip 20 for sealing is arranged between the partition 18 and the limiting edge 19.
For the present invention, it is preferable to ensure that the indoor air uniformly passes through each of the curtain sheets 4 on the mat. Aiming at the problem, the air inlet and outlet air path layout can be optimized. Preferably, the intake port 7 is provided at the top of the intake side rail 1, and the exhaust port 8 is provided at the bottom of the exhaust side rail 2.
Indoor air is guided to enter from the top of the air inlet side guide rail 1 through the fan 6, and under the dead weight effect and the wind pressure diversion effect of the fan 6, the indoor air tends to fill the cavity 9 of the whole air inlet side guide rail 1 downwards. At the same time, under the action of wind pressure, the air flows into the nearest curtain sheet 4 and passes through the curtain sheet 4 to flow to the cavity 9 of the exhaust side guide rail 2. Similarly, the air in the cavity 9 of the exhaust side rail 2 also tends to flow downward, and finally is discharged outside through the exhaust port 8 at the bottom.
As a further preference, the aperture of the vent hole 16 is proportional to the distance of the vent hole 16 from the intake port 7.
Since the wind pressure effect of the blower 6 is attenuated with the distance away from the blower 6, the wind pressure is larger near the intake port 7 and smaller far from the intake port 7. In order to make the air pass through each curtain sheet 4 more uniform, the vent hole 16 of the joint member 11 is provided with a hole diameter of: the smaller the aperture is closer to the intake port 7, the larger the aperture is further from the intake port 7, thereby balancing the overall wind pressure. The wind pressure is larger near the air inlet port 7, but the aperture of the vent hole 16 is smaller, the resistance is larger, and most air is not easy to enter the inside of the curtain sheet 4 through the vent hole 16; the air pressure at the position far away from the air inlet port 7 is attenuated, but the aperture of the vent hole 16 is larger, the resistance is smaller, and the air can more easily enter the inside of the curtain sheet 4 under the condition of smaller air pressure.
The ventilation sunshade curtain provided by the invention can actively ventilate the indoor and outdoor, exhaust the indoor old air out of the room, and enable the indoor air to pass through the inside of the curtain sheet 4 in the process, so that the curtain sheet 4 can keep the temperature similar to the indoor temperature for a long time by utilizing the indoor air, thereby playing a role of blocking the indoor and outdoor temperature transmission and saving the energy of an indoor air conditioner. Therefore, no excessive exhaust pipelines are required to be paved on the ceiling and the wall, the pipeline structure is simplified, and the construction difficulty is reduced. In addition, in the process of discharging indoor air out of the room through the curtain sheet 4, the sealing performance is fully considered, and the telescopic joint member 11 is designed for sealing. The extending mechanism has a linkage scheme, and the joint component 11 can be driven by the curtain bottom sheet 5 without control. Meanwhile, the structure of the vent holes 16 allows for uniformity of air passing through the curtain sheets 4, maximizing uniformity of air passing through each curtain sheet 4.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
