In other embodiments, the range of the third included angle γ is not limited to the above range, and may be adjusted according to the requirement.

However, the above-mentioned integrated cooker 100 has problems in use: the smoke outlet 1151 and the smoke inlet 12311 are capable of flowing back and flowing into the second smoke outlet 123 and the first smoke outlet 115, which results in reduced negative pressure dispersion in the smoke outlet 1151 and the first smoke outlet 115, and affects the absorption of smoke by the smoke outlet 1151 and the first smoke outlet 115, and the smoke absorbing effect of the integrated kitchen 100; on the other hand, the second smoke suction channel 123 may have a reverse flow of smoke, which may also affect the absorption of the smoke from the second smoke suction channel 123 and the smoke inlet 12311 to the smoke outside the integrated cooker 100, and further affect the smoke suction effect of the integrated cooker 100.

To solve the above problem, as shown in fig. 1 and 5, the handpiece 10 further includes a first drainage mechanism 13, where the first drainage mechanism 13 is disposed at a position where the first smoking channel 115 and the second smoking channel 123 are engaged, and the first drainage mechanism 13 can allow the oil smoke of the second smoking channel 123 to enter the first smoking channel 115 and block the oil smoke of the first smoking channel 115 from entering the second smoking channel 123. The first drainage mechanism 13 can prevent the smoke outlet 1151 and the smoke in the first smoke channel 115 from flowing back and filling into the second smoke channel 123 and the smoke inlet 12311. On the one hand, the negative pressure dispersion reduction in the smoke suction port 1151 and the first smoke suction channel 115 can be avoided, the smoke suction port 1151 and the first smoke suction channel 115 can absorb the oil smoke better, and the integrated kitchen 100 can have better oil smoke suction effect; on the other hand, the second smoke sucking channel 123 does not have reverse flowing smoke, so that the second smoke sucking channel 123 and the smoke inlet 12311 can not influence the absorption of the smoke outside the integrated cooker 100, and the better smoke sucking effect of the integrated cooker 100 is further ensured.

Referring to fig. 1 and 5, the structure of the first drainage mechanism 13 is described, as shown in fig. 1 and 5, the smoke collecting cavity mechanism 11 includes a communication channel 116, the second smoke channel 123 is communicated with the first smoke channel 115 through the communication channel 116, the first drainage mechanism 13 includes a drainage plate group 131 disposed in the communication channel 116, the drainage plate group 131 includes two drainage plates 1311, the drainage plate 1311 includes a connection end 131111 and a free end 131112, the connection end 131111 is connected with the communication channel 116, the free end 131112 and an inner wall of the communication channel 116 are disposed at intervals to form a first communication port 15, the drainage plates 1311 are disposed at intervals from the connection end 131111 to the free end 131112 in the same group of drainage plates 131 along a horizontal direction, the free ends 131112 of the two drainage plates 1311 in the same group 131 are disposed at intervals along the horizontal direction to form a second communication port 1312, and the second communication port 1312 is communicated with the first communication port 15. When the oil smoke flows from top to bottom, the oil smoke gathers together and rises, so the oil smoke more easily passes through the first drainage mechanism 13. In contrast, when the oil smoke flows from bottom to top, the two drainage portions 13111 form a structure similar to a shower, the oil smoke collides with the outwardly expanding obstacle to form a dispersion potential, the oil smoke forms a dispersion flow, the pressure of the oil smoke increases along with the flow direction, the pressurization is called a reverse pressure gradient, the oil smoke decelerates along the direction from bottom to top, after reaching a specific distance, the flow of the oil smoke is reversed, the oil smoke flows back from top to bottom, the dispersion flow is difficult to maintain, and the flow resistance generated by the dispersion flow is large, so that the oil smoke is difficult to flow from bottom to top to pass through the first drainage mechanism 13. Compared with the traditional one-way valve which needs to be interrupted and opened by a movable part, the first drainage mechanism 13 does not need to be provided with the movable part, and has the advantages of simple structure, long service life and difficult occurrence of damage.

When the oil fume flows from top to bottom, although a certain obstacle exists on the road, the oil fume is hardly influenced, so that the oil fume is easier to pass through.

In addition, as shown in fig. 1 and fig. 5, when the oil smoke flows from top to bottom, the first drainage mechanism 13 can realize the effect of reversing and rectifying the oil smoke coming out of the second smoke suction channel 123, the oil smoke coming out of the second smoke suction channel 123 can be converted into a steady flow state from a turbulent flow state after passing through the first drainage mechanism 13, the oil smoke coming out of the second smoke suction channel 123 in the steady flow state can be well mixed with the oil smoke in the first smoke suction channel 115, the mutual interference of two oil smoke is avoided, and the better absorption effect of the two oil smoke after being more stably mixed is facilitated. In addition, the oil smoke that second smoking passageway 123 comes out can carry out certain complementary action to the oil smoke in the first smoking passageway 115, and the oil smoke of two strand after being convenient for mixes is better absorbed by fan system.
