Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind cap technology, and more specifically, to a wind cap with ventilation and decondensation functions. Background Technology
[0002] A ventilation hood is a device used for ventilation, typically installed on the roof or vents of a building to improve indoor ventilation. It works by utilizing natural wind speeds to drive a turbine and promote air convection between indoors and outdoors. This accelerates any parallel airflow and transforms it into a vertical upward flow, thereby removing heat, moisture, and stale air from the room and improving the indoor environment.
[0003] There are various types of wind hoods, including umbrella-shaped wind hoods, louvered wind hoods, and non-powered wind hoods. In winter, when the indoor temperature is higher than the outdoor temperature, especially when the indoor humidity is high, condensation easily forms on the inner wall of the hood. If this condensation cannot be discharged in time, it will accumulate inside the hood, causing it to become damp. This can easily breed bacteria, mold, and other harmful substances, which can harm human health, shorten the lifespan of the hood, and also take up space, obstructing normal airflow and affecting ventilation. Utility Model Content
[0004] The main purpose of this invention is to provide a wind cap with ventilation and decondensation functions, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A ventilator with ventilation and decondensation function includes a fixed base, and a ventilator is movably sleeved on the top of the fixed base;
[0007] The shroud includes a rotating ring, a plurality of inner lining plates are fixedly installed on the top of the rotating ring, a top plate is fixedly installed on the top of the plurality of inner lining plates, a sleeve is fixedly installed on the bottom of the top plate, a plurality of outer plates are fixedly installed on the outer side of the bottom of the top plate, a bottom ring is fixedly installed on the bottom of the plurality of outer plates, and a heat dissipation groove is formed between the plurality of inner lining plates.
[0008] Preferably, the upper and lower ends of the plurality of outer side plates are respectively fixedly installed at an incline between the top plate and the bottom ring, and a ventilation groove is formed between the plurality of outer side plates. The bottom of the top plate is arc-shaped, and the heat dissipation groove and the outer side plates are both arc-shaped. The outer side plates are located outside the inner lining plate.
[0009] Preferably, the outer surface of the lower end of the rotating ring is inclined and forms a drainage groove between it and the bottom ring. The multiple outer side plates and multiple inner lining plates are interleaved with each other, and the multiple heat dissipation grooves and multiple ventilation grooves are interleaved with each other.
[0010] Preferably, the fixed base includes a mounting base tube, an air outlet top tube is fixedly mounted on the top of the mounting base tube, the upper diameter of the air outlet top tube is smaller than the lower diameter of the air outlet top tube, a support frame is fixedly mounted on the top of the air outlet top tube, an auxiliary frame is fixedly mounted on the top of the support frame, a support rod is fixedly mounted inside the support frame and the auxiliary frame, and a ball bearing is rotatably mounted on the top of the support rod.
[0011] Preferably, the inner part of the sleeve is movably fitted onto the top of the ball bearing, the rotating ring is movably fitted onto the outer surface of the mounting base pipe, and the rotating ring is located below the air outlet top pipe.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. By setting an exhaust pipe, the exhaust pipe separates the lower ends of the inner lining plate and the outer side plate. When condensation occurs at the bottom of the top plate, the fan hood is prone to shaking when it rotates, causing the condensation on the inner wall of the top plate to slide down from the inner wall of the inner lining plate and flow out from the outer surface of the exhaust pipe through the exhaust pipe from the heat dissipation groove and the drainage groove, thereby removing the condensation, improving the service life of the fan hood and the ventilation effect.
[0014] 2. By setting up interlocking heat dissipation grooves and ventilation grooves, rainwater will come into contact with the outer surface of the inner lining plate after passing through the ventilation grooves between the outer side panels. This allows the rainwater to slide down the outer surface of the inner lining plate to the outside of the air outlet pipe and be discharged from the drainage groove through the heat dissipation groove, thus preventing rainwater backflow.

Detailed Implementation
[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0021] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a ventilator with ventilation and decondensation function, including a fixed base 1 and a ventilator 2, wherein the ventilator 2 is movably sleeved on the top of the fixed base 1;
[0022] like Figure 3 As shown, the fan cover 2 includes a rotating ring 21, an inner liner 22, and an outer liner 26. There are multiple inner liner 22s, which are fixedly connected to the top of the rotating ring 21. A top plate 25 is fixedly installed on the top of the multiple inner liner 22s, and a sleeve 24 is fixedly installed on the bottom of the top plate 25. There are multiple outer liner 26s, which are fixedly connected to the outer side of the bottom of the top plate 25. A bottom ring 27 is fixedly installed on the bottom of the multiple outer liner 26s, and a heat dissipation groove 23 is formed between the multiple inner liner 22s.
[0023] The upper and lower ends of multiple outer side plates 26 are respectively fixedly installed at an incline between the top plate 25 and the bottom ring 27, and ventilation grooves 29 are formed between the multiple outer side plates 26. The bottom of the top plate 25 is arc-shaped, and the heat dissipation groove 23 and the outer side plates 26 are both arc-shaped. The outer side plates 26 are located outside the inner lining plate 22.
[0024] Multiple outer side plates 26 are fixedly installed at their upper and lower ends at an angle between the top plate 25 and the bottom ring 27, so that ventilation grooves 29 are formed between the multiple outer side plates 26 in an inclined state. At this time, when the external wind blows into the interior of the outer side plates 26, it will cause the wind cover 2 to rotate on the top of the fixed base 1, which facilitates ventilation. The rotation of the wind cover 2 facilitates the condensation on the inner wall of the inner lining plate 22 to slide off from the side of the inner lining plate 22.
[0025] like Figure 3 As shown, the outer surface of the lower end of the rotating ring 21 is inclined, and a drainage groove 28 is formed between it and the bottom ring 27. Multiple outer plates 26 and multiple inner lining plates 22 are intertwined, and multiple heat dissipation grooves 23 and multiple ventilation grooves 29 are intertwined.
[0026] Because the heat dissipation slots 23 and ventilation slots 29 are intertwined, rainwater will come into contact with the outer surface of the inner lining plate 22 after passing through the ventilation slots 29 between the outer side plates 26, and will be discharged from the drainage slots 28 along the outer surface of the inner lining plate 22, thus preventing rainwater from entering the interior of the hood 2 through the ventilation slots 29 and preventing rainwater backflow.
[0027] The fixed base 1 includes a mounting base tube 11, an air outlet top tube 12 is fixedly mounted on the top of the mounting base tube 11, the upper diameter of the air outlet top tube 12 is smaller than the lower diameter of the air outlet top tube 12, a support frame 13 is fixedly mounted on the top of the air outlet top tube 12, an auxiliary frame 14 is fixedly mounted on the top of the support frame 13, a support rod 15 is fixedly mounted inside the support frame 13 and the auxiliary frame 14, and a ball bearing 16 is rotatably mounted on the top of the support rod 15.
[0028] Through the exhaust pipe 12, indoor air is discharged through the top of the exhaust pipe 12. The exhaust pipe 12 separates the lower ends of the inner lining plate 22 and the outer side plate 26, so that the indoor air must first pass above the inner lining plate 22, and then along the bottom of the top plate 25, and be discharged from the heat dissipation groove 23 and the ventilation groove 29. During the falling process, rainwater will come into contact with the outer side of the inner lining plate 22 and the exhaust pipe 12 through the ventilation groove 29, and be discharged from the drainage groove 28 through the heat dissipation groove 23 along the outer side of the exhaust pipe 12, thus realizing the discharge of rainwater.
[0029] The sleeve 24 is movably fitted inside the top of the ball bearing 16, and the rotating ring 21 is movably fitted on the outer surface of the mounting base pipe 11. The rotating ring 21 is located below the air outlet top pipe 12.
[0030] The working process of this utility model is as follows:
[0031] Multiple outer side plates 26 are fixedly installed at their upper and lower ends at an angle between the top plate 25 and the bottom ring 27, so that the ventilation groove 29 formed between the multiple outer side plates 26 is in an inclined state. At this time, when the external wind blows into the interior of the outer side plates 26, it will cause the wind cover 2 to rotate on the top of the fixed base 1. When the indoor air passes through the mounting bottom pipe 11 and the air outlet top pipe 12, and is discharged through the heat dissipation groove 23 and the outer side plates 26, it will come into contact with the bottom of the top plate 25, causing condensation to form on the bottom of the top plate 25.
[0032] Because the wind force of natural wind is not evenly blown on the outer side plate 26, the wind cover 2 will rotate unevenly on the top of the fixed base 1. When the wind cover 2 rotates, it is easy to shake, causing the condensate on the inner wall of the top plate 25 to slide down from the inner wall of the inner lining plate 22 and out the outer surface of the air outlet pipe 12, and flow out from the heat dissipation groove 23 and the drainage groove 28 through the air outlet pipe 12.
[0033] When it is rainy or snowy outside, rainwater will come into contact with the outer surface of the inner lining plate 22 after passing through the ventilation groove 29 between the outer side plates 26. It will slide down the outer surface of the inner lining plate 22 to the outside of the rotating ring 21, so that the rainwater can be discharged through the drainage groove 28. This prevents rainwater from entering the interior of the fixed base 1 through the ventilation groove 29 and avoids the occurrence of rainwater backflow.
[0034] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
