Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: the utility model provides a cover that induced drafts can be dismantled to magnetism, like figure 1 and figure 2, including seting up annular fixed slot 11 at exhaust pipe 1 lower terminal surface, be equipped with magnet 12 in the fixed slot 11, induced draft cover 14 upper end be equipped with induced draft cover 14 in communicating pipe 13 of intercommunication, communicating pipe 13 upper end is equipped with the fixed cylinder 131 that gets into in the fixed slot 11, fixed cylinder 131 and the coaxial setting of communicating pipe 13, fixed cylinder 131 is iron system and contradicts with magnet 12.

As shown in fig. 1 and fig. 2, after the fixing cylinder 131 is moved into the fixing groove 11, the fixing cylinder 131 receives the suction force of the magnet 12, and is further fixed in the fixing groove 11, the suction hood 14 at the lower end of the communicating pipe 13 is communicated with the exhaust pipe 1 at the moment, so that pollutants can be conveniently sucked into the suction hood 14, when the suction hood 14 needs to be replaced, a user only needs to pull the fixing cylinder 131 on the suction hood 14 in a direction away from the fixing groove 11, at the moment, the pulling force is greater than the suction force of the magnet 12 on the fixing cylinder 131, and the suction hood 14 is convenient to detach from the exhaust pipe 1, and the operation is simple.

As shown in fig. 1 and 2, the exhaust duct 1 is provided with a driving member for driving the fixed cylinder 131 to be separated from the magnet 12. The driving piece is arranged to push the fixing cylinder 131 out of the fixing groove 11, so that the air suction hood 14 can be detached from the exhaust pipe 1 more conveniently.

As shown in fig. 1 and fig. 2, the magnet 12 is annular and is connected on the wall of the fixing groove 11 in a sliding manner, the driving member includes a moving rod 15 disposed on the outer wall of the magnet 12, one end of the moving rod 15 away from the magnet 12 penetrates through the exhaust duct 1, and a driving groove 151 is disposed on the wall of the exhaust duct 1 for the moving rod 15 to drive the magnet 12 to move along the length direction of the fixing groove 11, and after the fixing cylinder 131 enters the fixing groove 11, a clamping block 152 abutting against the lower end of the exhaust duct 1 is disposed on the inner wall of the fixing cylinder 131. At this time, after the user moves the fixed cylinder 131 into the fixed slot 11, the magnet 12 adsorbs the fixed cylinder 131, so that the movable rod 15 abuts against the lower end slot wall of the driving slot 151, at this time, the magnet 12 is limited to continue to move towards the notch of the fixed slot 11, the adsorption force of the magnet 12 on the fixed cylinder 131 fixes the position of the fixed cylinder 131 in the fixed slot 11, when the magnet 12 needs to be separated from the fixed cylinder 131, the user upwards pushes the movable rod 15, so that the movable rod 15 drives the magnet 12 to move towards the direction away from the fixed cylinder 131, until the distance separating the magnet 12 from the fixed cylinder 131 is not enough to adsorb the fixed cylinder 131, and the fixed cylinder 131 receives the limit of the fixture block 152, and cannot move along with the movement of the magnet 12, when the movable rod 15 abuts against the lower end slot wall of the driving slot 151, the fixture block 152 abuts against.

Referring to fig. 1 and 2, a first fixing plate 16 is disposed on an outer wall of the exhaust duct 1, the first fixing plate 16 is disposed below the driving groove 151 and is provided with a first cylinder 161 connected to the moving rod 15, and a piston rod of the first cylinder 161 is connected to an end of the moving rod 15 extending out of the exhaust duct 1. The piston rod of the first cylinder 161 drives the moving rod 15 to move in the driving groove 151, so that the labor is saved, and a user only needs to receive the air suction cover 14 below the air suction cover 14, and the operation is convenient.

As shown in fig. 1 and 3, the air suction hood 14 is shaped like a bucket with a downward opening; or the air suction hood 14 is in a bucket shape with a horizontal opening, namely the air inlet direction is horizontal. At this moment, the openings of the air suction hoods 14 are arranged differently, so that a user can conveniently detach and install different air suction hoods 14 on the exhaust pipe 1, and the use requirements are met.

As shown in fig. 4 and 5, or, the air suction cover 14 is an annular cover body 18 with a hollow cavity, the communication pipe 13 is communicated with the inner cavity of the cover body 18, the inner annular wall of the cover body 18 is provided with a plurality of air vents 181 communicated with the hollow cavity, at this time, the pollutants are in the middle of the cover body 18, and the air vents 181 absorb the pollutants in 360 degrees in an all-round manner, so that the pollutants can be conveniently discharged.

Example 2: the utility model provides a cover that induced drafts can be dismantled to magnetism, the difference with embodiment 1 lies in, as figure 6, magnet 12 sets up on the relative cell wall of fixed slot 11, the driving piece is including seting up two connecting holes 17 at the bottom of fixed slot 11 tank, two connecting holes 17 set up relatively in exhaust pipe 1 center, and all slide in each connecting hole 17 and be connected with ejector pin 171, the one end and the fixed section of thick bamboo 131 up end conflict of ejector pin 171, the lateral wall of ejector pin 171 is equipped with the horizontal push rod 172 that extends exhaust pipe 1 outer wall, exhaust pipe 1 inner wall is seted up and is supplied push rod 172 along with ejector pin 171 along the spout 173 that connecting hole 17 length. When the user pushes the push rod 172 towards the direction of the air suction hood 14, the push rod 172 drives the push rod 171 to move towards the fixed cylinder 131, so as to generate a downward extrusion force on the fixed cylinder 131, and the fixed cylinder 131 overcomes the adsorption force of the magnet 12 on the fixed cylinder 131 to move out of the fixed groove 11, so that the operation is convenient.

Referring to fig. 6, the outer wall of the exhaust duct 1 is provided with a second fixing plate 174, the second fixing plate 174 is located below the sliding slot 173 and is provided with a second cylinder 175 connected with the push rod 172, and a piston rod of the second cylinder 175 is connected to one end of the push rod 172 extending out of the exhaust duct 1. At this time, the piston rod of the second cylinder 175 drives the push rod 172 to move back and forth in the sliding slot 173, so that the fixed cylinder 131 is conveniently pushed out from the fixed slot 11, labor is saved, and operation is facilitated.

As shown in fig. 6, an abutting plate 176 is provided at an end of the push rod 171 abutting against the upper end surface of the fixed cylinder 131. The abutting plate 176 is provided to facilitate the push rod 171 to push out the fixed cylinder 131.
