Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, and more specifically, to an anti-clogging hood. Background Art

[0002] As one of the common ventilation equipment, the hood is usually installed at the vent or exhaust outlet of the fresh air duct. It can effectively prevent external impurities from entering the fresh air duct and reduce the problem of blockage in the fresh air duct.

[0003] Publication No. CN217876301 U discloses a hood for a factory fresh air system, and its technical solution includes a hood body and a fixing seat, the hood body includes a rotating part and a fixing part, the rotating part is arranged on the upper side of the fixing part, and the rotating part is rotatably connected to the fixing part. The fixing seat is connected to a building, and the fixing seat includes a vertically arranged locking sleeve, the locking sleeve has a through hole extending vertically and capable of accommodating the fixing part, and the inner wall of the locking sleeve has a protrusion protruding toward the inside of the locking sleeve and capable of locking / releasing the fixing part.

[0004] The above technical solution can quickly lock the hood body by setting the locking sleeve, thereby increasing the installation speed of the hood and improving work efficiency. However, in rainy and snowy weather, rain and snow will enter the hood body through the exhaust port on the hood body, and the above technical solution does not provide a structure for clearing rain and snow on the hood body, resulting in blockage of the exhaust port on the hood body, affecting the exhaust effect of the fresh air duct.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an anti-clogging wind hood, which solves the problem that rain and snow may cause the wind hood to be blocked in rainy and snowy weather, thereby affecting the exhaust effect of the fresh air duct.

[0007] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: an anti-clogging hood, comprising a base and a hood body connected to each other, a fixing ring fixedly connected to the inner bottom surface of the base, a plurality of support rods fixedly connected to the fixing ring, gaps between the support rods, baffles detachably connected to the support rods, a distance between the baffle and the fixing ring and the hood body and the base respectively, a guide plate fixedly connected to the baffle, and a discharge assembly for discharging rain and snow outwards is provided at the bottom of the base.

[0008] By adopting the above technical solution, in rainy and snowy weather, rain and snow will enter the hood body through the exhaust port and contact the guide plate in the hood body. At this time, the rain and snow are affected by the guide plate, start to move along the side wall of the guide plate, and fall between the fixed ring and the base. At this time, through the setting of the discharge component, the rain and snow between the fixed ring and the base can be discharged outward, thereby achieving the effect of clearing the rain and snow in the hood body, avoiding the hood body from being blocked by rain and snow, and improving the exhaust effect. Through the setting of a number of support rods, the baffle and the guide plate can be supported without affecting the exhaust effect of the hood body, thereby avoiding affecting the normal use of the hood.

[0009] The utility model is further configured as follows: the discharge assembly includes a plurality of through grooves opened at the bottom of the base, and a rotating plate is rotatably connected to one side of the through grooves close to the fixed ring. The rotating plate and the fixed ring are connected by a spring hinge. When the spring hinge is in a natural state, the rotating plate and the side wall of the through groove are in contact with each other.

[0010] By adopting the above technical solution, when rain and snow enter between the fixed ring and the base, they will begin to accumulate between the fixed ring and the base. At this time, the spring hinge begins to deform due to the weight of the rain and snow itself, and at the same time drives the rotating plate to rotate and separate from the through groove. At this time, the rain and snow are discharged outward through the through groove. After the rain and snow are discharged outward, the spring hinge loses its restriction and begins to recover its deformation, driving the rotating plate back to its original position, thereby achieving the effect of discharging the rain and snow between the fixed ring and the base outward.

[0011] The utility model is further configured as follows: an air guide plate is fixedly connected to the bottom of the baffle.

[0012] By adopting the above technical solution, it is possible to prevent air from staying at the bottom of the baffle, thereby improving the exhaust effect of the hood body.

[0013] The utility model is further configured as follows: a connecting ring is provided on the plurality of support rods, a plurality of through holes are opened on the connecting ring, the plurality of through holes and the plurality of support rods are slidably connected, a placement groove for placing the baffle is opened on the connecting ring, the baffle and the placement groove are clamped to each other by a clamping piece, and the connecting ring and the plurality of support rods are connected by an adjusting piece.

[0014] By adopting the above technical scheme, when the baffle plate and the plurality of support rods are installed to each other, the baffle plate is placed in the placement groove on the connecting ring, and then the baffle plate and the placement groove are fixed to each other by the clamping member, and then the connecting ring is driven to start sliding along the side walls of the plurality of support rods, and the distance between the connecting ring and the fixing ring is adjusted by the adjusting member to avoid excessive distance between the connecting ring and the fixing ring causing rain and snow to enter the gap between the plurality of support rods, thereby improving the anti-blocking effect of the hood, and after the distance between the connecting ring and the fixing ring is adjusted to an appropriate size, the clamping block and the clamping groove are clamped to each other to achieve the effect of installing the baffle plate and the support rod.

[0015] The utility model is further configured as follows: the clamping part includes a plurality of arc grooves provided on the side wall of the fixing ring, a plurality of the arc grooves and the placement grooves are connected to each other, a plurality of the arc grooves are slidably connected with shift blocks, a limiting block is fixedly connected to the side wall of the shift block, a limiting groove is provided on the side wall of the baffle for the limiting block to slide, and when the shift block completely enters the arc groove, the top and bottom of the limiting block are in contact with the side wall of the limiting groove.

[0016] By adopting the above technical scheme, when the baffle plate and the placement groove need to be fixed to each other, the shift block is driven to start sliding along the arc groove, and at the same time, the limit block is driven to slide in the direction of the limit groove. When the shift block completely enters the arc groove, the limit block is affected by the shift block and connected to the limit groove. At this time, the baffle plate and the placement groove are restricted by the limit block and cannot be separated from each other, thereby achieving the effect of fixing the baffle plate and the placement groove to each other. When the baffle plate and the placement groove need to be separated from each other, it is only necessary to drive the shift block back to its original position, drive the limit block and the limit groove to separate from each other, and at this time, the restriction between the baffle plate and the placement groove is cancelled, thereby achieving the effect of disassembling the baffle plate and the placement groove.

[0017] The utility model is further configured as follows: the adjusting member includes a plurality of grooves opened on the side walls of the through hole, a clamping block is slidably connected in the groove, the groove and the clamping block are connected by a spring, and a plurality of clamping slots are opened on the side walls of the support rods, and when the spring is in a natural state, the clamping block and the clamping slot are clamped with each other.

[0018] By adopting the above technical solution, when it is necessary to adjust the distance between the connecting ring and the fixed ring, pressure is applied to the connecting ring to drive the block and the slot to separate from each other and move into the groove, and at the same time drive the spring to start to deform and compress. At this time, the connecting ring cancels the restriction and starts to move downward. When the connecting ring moves to the position where the block and the other slot are aligned with each other, the spring loses the restriction and starts to deform and recover, and drives the block and the other slot to engage with each other, thereby achieving the effect of adjusting the distance between the connecting ring and the fixed ring. Through the setting of the spring, it is possible to drive the connecting ring to move while driving the block and the slot to be fixed to each other.

[0019] The utility model is further configured as follows: the guide plate covers the connecting ring, and a plurality of the support rods penetrate the guide plate and are slidably connected to the guide plate.

[0020] By adopting the above technical solution, the blocking effect of the guide plate on rain and snow can be further improved.

[0021] To sum up, the utility model has the following beneficial effects: in rainy and snowy weather, rain and snow will enter the hood body through the exhaust port and contact the guide plate in the hood body. At this time, the rain and snow are affected by the guide plate, start to move along the side wall of the guide plate, and fall between the fixed ring and the base. At this time, through the setting of the discharge component, the rain and snow between the fixed ring and the base can be discharged outward, thereby achieving the effect of clearing the rain and snow in the hood body, avoiding the hood body from being blocked by rain and snow, and improving the exhaust effect. Through the setting of a number of support rods, the baffle and the guide plate can be supported without affecting the exhaust effect of the hood body, thereby avoiding affecting the normal use of the hood.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] An anti-clogging hood, such as Figure 1-Figure 5 As shown, it comprises a base 1 and a hood body 2 connected to each other, a fixing ring 3 is fixedly connected to the inner bottom surface of the base 1, a plurality of support rods 4 are fixedly connected to the fixing ring 3, there are gaps between the plurality of support rods 4, baffles 5 are detachably connected to the plurality of support rods 4, there are gaps between the baffles 5 and the fixing ring 3 and the hood body 2 and the base 1 respectively, a guide plate 20 is fixedly connected to the baffle 5, a discharge assembly for discharging rain and snow outwards is provided at the bottom of the base 1, in rainy and snowy weather, rain and snow will enter the hood body 2 through the exhaust port, and at the same time, the guide plate 20 in the hood body 2 When the hood body 2 is in contact with each other, the rain and snow are affected by the guide plate 20, start to move along the side wall of the guide plate 20, and fall between the fixing ring 3 and the base 1. At this time, the rain and snow between the fixing ring 3 and the base 1 can be discharged outward through the setting of the discharge component, thereby achieving the effect of clearing the rain and snow in the hood body 2, avoiding the hood body 2 from being blocked by rain and snow, and improving the exhaust effect. Through the setting of a number of support rods 4, the baffle 5 and the guide plate 20 can be supported without affecting the exhaust effect of the hood body 2, thereby avoiding affecting the normal use of the hood.

[0032] like Figure 1-Figure 5As shown, the discharge assembly includes a plurality of through grooves 6 opened at the bottom of the base 1, and a rotating plate 7 is rotatably connected to one side of the plurality of through grooves 6 close to the fixed ring 3. The rotating plate 7 and the fixed ring 3 are connected by a spring hinge 8. When the spring hinge 8 is in a natural state, the rotating plate 7 and the side walls of the through grooves 6 contact each other. When rain and snow enter between the fixed ring 3 and the base 1, rain and snow will begin to accumulate between the fixed ring 3 and the base 1. At this time, the spring hinge 8 begins to deform under the influence of the weight of the rain and snow itself, and at the same time drives the rotating plate 7 to rotate and separate from the through grooves 6. At this time, the rain and snow are discharged outwardly through the through grooves 6. After the rain and snow are discharged outwardly, the spring hinge 8 loses its restriction and begins to recover its deformation, driving the rotating plate 7 back to its original position, thereby achieving the effect of discharging rain and snow between the fixed ring 3 and the base 1 outwardly.

[0033] like Figure 1-Figure 5 As shown, a plurality of support rods 4 are provided with a connecting ring 10, a plurality of through holes 11 are provided on the connecting ring 10, and a plurality of through holes 11 are slidably connected to a plurality of support rods 4, a placement groove 12 for placing a baffle 5 is provided on the connecting ring 10, and the baffle 5 and the placement groove 12 are mutually clamped by a clamping member, and the connecting ring 10 and the plurality of support rods 4 are connected by an adjusting member, and the clamping member includes a plurality of arc grooves 13 provided on the side wall of the fixing ring 3, and the plurality of arc grooves 13 and the placement groove 12 are mutually conductive, and a shift block 14 is slidably connected in the plurality of arc grooves 13, and the shift block 14 is slidably connected in the plurality of arc grooves 13. The side wall of the baffle plate 5 is fixedly connected with the limit block 15, and the side wall of the baffle plate 5 is provided with a limit groove 16 for the limit block 15 to slide. When the shift block 14 completely enters the arc groove 13, the top and bottom of the limit block 15 are in contact with the side wall of the limit groove 16. The adjusting member includes a plurality of grooves 17 provided on the side wall of the through hole 11, and a clamping block 18 is slidably connected in the groove 17. The groove 17 and the clamping block 18 are connected by a spring 19. The side walls of the plurality of support rods 4 are provided with a plurality of clamping grooves 21. When the spring 19 is in a natural state, the clamping block 18 and the clamping groove 21 are clamped with each other.

[0034] When the baffle plate 5 and the supporting rods 4 are mounted on each other, the baffle plate 5 is placed in the placement groove 12 on the connecting ring 10, and then the shifting block 14 is driven to start sliding along the arc groove 13, and at the same time, the limiting block 15 is driven to slide in the direction of the limiting groove 16. When the shifting block 14 completely enters the arc groove 13, the limiting block 15 is affected by the shifting block 14 and connected to the limiting groove 16. At this time, the baffle plate 5 and the placement groove 12 are restricted by the limiting block 15 and cannot be separated from each other. Then the connecting ring 10 is driven to start sliding along the side walls of the supporting rods 4, and at the same time, The spring 19 is driven to start to deform and compress, and at this time, the connecting ring 10 is freed from restriction and starts to move downward. When the connecting ring 10 moves to the position where the block 18 and another slot 21 are aligned with each other, the spring 19 loses restriction and starts to deform and recover, and drives the block 18 and another slot 21 to engage with each other. In this way, the distance between the connecting ring 10 and the fixed ring 3 is adjusted to avoid excessive distance between the connecting ring 10 and the fixed ring 3 causing rain and snow to enter the gap between the support rods 4, thereby achieving the effect of installing the baffle 5 and the support rods 4.

[0035] like Figure 1-Figure 5 As shown, the guide plate 20 covers the connecting ring 10, and a plurality of support rods 4 penetrate the guide plate 20 and are slidably connected to the guide plate 20, which can further improve the blocking effect of the guide plate 20 on rain and snow.

[0036] like Figure 1-Figure 5 As shown, an air guide plate 9 is fixedly connected to the bottom of the baffle 5 , which can prevent air from staying at the bottom of the baffle 5 and improve the exhaust effect of the hood body 2 .

[0037] The normal use of the utility model is as follows: in rainy and snowy weather, rain and snow will enter the hood body 2 through the exhaust port, and at the same time contact the guide plate 20 in the hood body 2. At this time, the rain and snow are affected by the guide plate 20, begin to move along the side wall of the guide plate 20, and fall between the fixed ring 3 and the base 1, and begin to accumulate between the fixed ring 3 and the base 1. At this time, the spring hinge 8 begins to deform due to the weight of the rain and snow itself, and at the same time drives the rotating plate 7 to rotate and separate from the through groove 6. At this time, the rain and snow are discharged outwardly through the through groove 6. After the rain and snow are discharged outwardly, the spring hinge 8 loses the restriction and begins to deform and restore, driving the rotating plate 7 back to its original position, thereby achieving the effect of clearing the rain and snow in the hood body 2, avoiding the hood body 2 from being blocked by rain and snow, and improving the exhaust effect.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
