Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the safety check of the present embodiment comprises exhaust outlet 1, valve block 7, rotating shaft 3, position limit device 4, resetting means 11, valve block 7 is the single valve sheet, valve block 7 is installed in a side of exhaust outlet 1 by rotating shaft 3 and 3 rotates around the shaft, resetting means 11 is positioned at the valve block 7 that is used for supporting reset mode on the exhaust outlet 1, position limit device 4 is positioned at and is used for restriction valve block 7 opening angles on the exhaust outlet 1, so-called reset mode is that the cigarette machine is not when working, the state of valve block 7, the exhaust outlet 7 of the present embodiment is circular, and valve block 7 is aluminium matter non-ferrous metal thin material.Adopt the single valve sheet, can effectively avoid double valve sheet V-arrangement angle zone to produce mass air flow loss and vortex noise, valve block 7 is positioned at a side of exhaust outlet 1, is eccentric structure, can effectively avoid the valve block 7 rear problem that is difficult for resetting of kicking up, and is easy to use.
Particularly, one side of exhaust outlet 1 is provided with two rotary shaft holes 2, valve block 7 is provided with hangers 8, be provided with the valve block hole corresponding with rotary shaft hole 2 on the hangers 8, valve block 7 is connected rotating shaft and is connected with exhaust outlet 1 one sides by passing rotary shaft hole 2 with the valve block hole, two rotary shaft holes 2 of the present embodiment are two die mould circular holes and are symmetrical arranged, hangers 8 is semicircle, the spherical cap of an end band of rotating shaft 3, and the other end is threaded, during installation, valve block 7 is put into the corresponding position of exhaust outlet 1, then rotating shaft 3 is passed rotary shaft hole 2 and valve block hole 8 with an end of spherical cap, screw with nut 6 at last, simple in structure, easy for installation.
Further, described position limit device 4 is upper limit stop hook and the top that is positioned at rotary shaft hole 2, directly over being preferably, makes valve block 7 opening degrees near 90 ℃, and when the cigarette machine was worked, valve block 7 can be opened to greatest extent, discharged fume unobstructed; Resetting means 11 is for resetting stop hook and be positioned on the exhaust outlet 1 side relative with rotating shaft 3, preferably, resetting means 11 is positioned on the exhaust outlet 1 and the neutral position on the semicircle limits of rotating shaft 3 relative sides and the height that highest point is higher than rotating shaft 3, like this when valve block 7 resets, the upper surface of valve block 7 has certain inclination, when the outside has foreign material or oil droplet to fall, can fall in the cooking fume-collecting cup of kitchen ventilator along the inclined-plane, be not interposing at the surface of all falling valve block 7, prevent that valve block 7 surface and oil contaminants are too much, produce bonding, affect opening of valve block 7.
Further, the position limit device 4 of the present embodiment is provided with spacing blob of viscose 5, resetting means 11 is provided with the blob of viscose 10 that resets, because spacing blob of viscose 5 and the blob of viscose 10 that resets are soft, when the work of cigarette machine, the oil smoke mixed gas upwards blows afloat valve block 7 when contacting with position limit device 4 to maximum opening or the cigarette machine quits work, and valve block 7 is from open mode to reset mode, when contacting with resetting means 11, be soft contact, crack the noise that produces in the time that metal and Metal Contact can more effectively being avoided.
Preferably, be provided with projection 9 with resetting means 11 contacted positions on the valve block 7, owing to being provided with the blob of viscose 10 that resets on the resetting means, when therefore valve block 7 resets, projection 9 also is soft the contact with the blob of viscose 10 that resets, and can not produce noise, and projection 9 is that point contacts with the blob of viscose 10 that resets, the oil stain bonded part is few, can prevent further that valve block 7 rear being pasted by grease that reset is difficult for opening.
When valve block 7 is in reset mode, gap between valve block 7 and exhaust outlet 1 inwall is that 1/10 of exhaust outlet 1 area is arranged, since the gap exist the cigarette machine to quit work the time, the condensed oil droplet of smoke pipe can tumble in the lubricating cup by the gap, solved on the market the existing residual oil stain of safety check and accumulated over a long period storages, scleroma on valve block 7 and resetting means, made valve block 7 stick greasy dirt and occur boning and open the problem that has some setbacks.
More preferably, be provided with stiffening rib on the valve block 7, and stiffening rib is 1.0 times of valve block 7 thickness with respect to the height of valve block 7, the mechanical strength that the limited increase valve block 7 of energy is set of stiffening rib, and valve block 7 is had by the oil smoke air-flow blow afloat rapidly needed slight resistance, make valve block 7 easier being raised up, smoke discharging effect is better.
On the valve block 7 take the straight line between the diaxon ear as boundary, the weight of the part that area is little is 1/4 of valve block 7 overall weight, can do uneven lever motion with rotating shaft 3 when this weight specific energy makes valve block 7 reset from opening to further, can with the fastest speed freely falling body, more easily reset.
