Detailed Description
The invention will now be further described with reference to the accompanying drawings, in which:
example (b):
the utility model provides an energy-saving fume chamber, as shown in fig. 1 and 2, including the cabinet body 11, exhaust pipe 12 and speed governing fan 13, the cabinet body 11 is equipped with plenum 21, the cabinet body 11 is equipped with air inlet 22 and the gas vent 23 that communicates in plenum 21 upper and lower both ends respectively, exhaust pipe 12 both ends communicate with speed governing fan 13 and gas vent 23 respectively, air inlet 22 and atmosphere intercommunication, the 11 horizontal sliding connection of the cabinet body has the deep bead 31 that is located plenum 21, deep bead 31 sets up 2 altogether, 2 the slip direction of individual deep bead 31 on the cabinet body 11 is the same, 2 deep bead 31 are parallel to each other, 2 deep bead 31 sets up respectively in air inlet 22's both sides, the thing pole 14 is put to a plurality of deep beads 31 of wearing to locate of cabinet body 11 fixedly connected with, it extends along the slip direction of.
The cabinet body 11 is rotatably connected with a linkage gear 32, the linkage gear 32 is fixedly connected with a linkage shaft 35, the linkage shaft 35 is fixedly connected with a rotating handle 36 positioned outside the cabinet body 11, the rotating handle 36 is slidably connected with a locking pin 37, and the cabinet body 11 is provided with a clamping groove 38 matched with the locking pin 37. The 2 wind deflectors 31 are fixedly connected with racks 33 meshed with the linkage gears 32, the 2 racks 33 face oppositely, and the cabinet body 11 is provided with accommodating grooves 15 for accommodating the racks 33 and the linkage racks 33.
The linkage gear 32 is fixedly connected with a winding drum 34 positioned above the air deflector 24, the winding drum 34 is wound with 2 pull ropes 25, the cabinet body 11 is rotatably connected with 2 air deflectors 24 positioned at the air inlet 22, and the 2 pull ropes 25 are respectively and fixedly connected with different air deflectors 24. An elastic member 26 is arranged between the air deflector 24 and the cabinet body 11, and the elastic member 26 is a spring with two ends respectively fixedly connected with the air deflector 24 and the cabinet body 11.
The sample to be ventilated is placed on the holding rod 14, and the object is supported by the holding rod 14, so that the object can be stably placed in the ventilation chamber 21. The speed regulation fan 13 is started, the speed regulation fan 13 is enabled to pump out air in the ventilation chamber 21 through the exhaust pipe 12, negative pressure is formed in the ventilation chamber 21, air outside the cabinet body 11 is sucked into the ventilation chamber 21 through the negative pressure in the ventilation chamber 21, and therefore the air sequentially passes through the air inlet 22, the ventilation chamber 21, the exhaust port 23, the exhaust pipe 12 and the speed regulation fan 13, and the function of ventilating objects on the object placing rod 14 is achieved.
When the distance between the wind shields 31 needs to be adjusted, the handle 36 is rotated, the linkage gear 32 is driven to rotate through the linkage shaft 35, the linkage gear 32 drives the 2 wind shields 31 to move in opposite directions through the 2 racks 33 facing opposite directions, and therefore the effect of adjusting the distance between the wind shields 31 is achieved. When the linkage gear 32 rotates, the winding drum 34 is driven to rotate, the winding drum 34 adjusts the angle of the air deflector 24 through the pull rope 25, and therefore the flowing angle of air at the air inlet 22 is adjusted, and the ventilation effect of the sample is improved.
The embodiment has the following advantages:
when a sample with a small volume needs to be ventilated, the sample is placed above the air inlet 22, then 2 air baffles 31 slide on the cabinet body 11 in the direction close to the air inlet 22, the air entering the ventilation chamber 21 through the air inlet 22 is blocked by the air baffles 31, and the air flows at the position close to the sample, so that the sample can be ventilated by the flowing air more effectively. After the 2 wind shields 31 slide in the direction close to the air inlet 22, the distance between the 2 wind shields 31 is reduced and the space is narrowed, so that the air flow rate at the sample is accelerated when the air flow rate extracted by the speed regulation fan 13 is unchanged. And then can be under the prerequisite of guaranteeing that the air velocity of sample department is not reduced, properly adjust and reduce the operating speed of speed governing fan 13 and reduce the air mass flow of speed governing fan 13 to can reduce speed governing fan 13 consumption, reach the advantage that the consumption is lower, play energy-conserving effect.
In the process of sliding the wind deflector 31 on the cabinet 11, the rack 33 is driven to move, and the rack 33 drives the other rack 33 and the wind deflector 31 to move in opposite directions through the linkage gear 32 meshed with the rack 33. The effect that realizes 2 deep bead 31 of simultaneous drive and remove makes 2 deep bead 31 move to opposite direction to conveniently adjust the distance between 2 deep bead 31, reach the effect of facilitating the use.
When the position for placing the sample to be ventilated is changed, the air deflector 24 is rotated on the cabinet body 11, and the flow direction of the air at the air inlet 22 is changed through the air deflector 24, so that the air flows to the sample to be ventilated. The air flow speed of the sample is ensured, and the effect of improving the ventilation effect is achieved.
When the wind deflector 31 moves in a direction close to the air inlet 22, the linkage gear 32 drives the winding drum 34 to rotate, so that the winding drum 34 winds the pulling rope 25, and the 2 wind deflectors 24 are pulled by the pulling rope 25 to turn upwards, so that the air in the air inlet 22 can flow upwards, and the flowing air can be concentrated on a sample placed above the air inlet 22. The air circulation speed of the sample is improved, and the effect of improving the ventilation effect is achieved.
When the wind deflector 31 moves in a direction away from the air inlet 22, the linkage gear 32 drives the reel 34 to rotate, so that the reel 34 releases the pull rope 25, the elastic piece 26 drives the wind deflector 24 to turn downwards, and therefore the wind deflector 24 guides air to flow in a direction close to the wind deflector 31, and the flowing air is dispersed along with the increase of the distance of the wind deflector 31. The flowing air is more uniformly distributed among the 2 wind shields 31, and the effect of improving the ventilation effect of the sample is achieved.
The rotating handle 36 is rotated outside the cabinet body 11, so that the rotating handle 36 drives the linkage gear 32 to rotate through the linkage shaft 35, the linkage gear 32 drives the rack 33 and the wind shield 31 to move in the cabinet body 11, and the effect of conveniently driving the wind shield 31 to move is achieved.
When the wind deflector 31 is moved to a proper position, the locking pin 37 is slid on the turning handle 36, so that the locking pin 37 is inserted into the catching groove 38 on the cabinet 11. The locking pin 37 is clamped with the cabinet body 11, so that the rotating handle 36 is prevented from rotating, and the rotating handle 36, the linkage gear 32 and the wind shield 31 are locked.
The rack 33 and the linkage gear 32 are accommodated through the accommodating groove 15, so that the resistance of the rack 33 and the linkage gear 32 to the flowing air is reduced, the air flowing speed of the sample is ensured, and the ventilation effect of the sample is ensured.
In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
