[0033] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following examples can be combined with each other without conflict.

[0034] Please refer to Figures 1 to 8 As shown in the drawings, the present application provides an exhaust type germinator 100, which has a germination space 101 and can humidify the material placed therein. In some embodiments, the material humidified thereby is grain for germination, and the exhaust type germinator 100 is used as a grain germinator. In other embodiments, the material humidified thereby can also be other materials, such as materials that need to be kept moist and fresh by water mist, etc., and the exhaust type germinator 100 is used as a fresh-keeping machine.

[0035] The exhaust type germinator 100 includes a main body 1 having a top opening and a cover 2 covering the top opening to enclose the germination space 101. The exhaust type germinator 100 includes a water mist generator 15 for generating water mist in the germination space 101 and an airflow generator for driving the water mist flow. The cover 2 is provided with an exhaust passage in communication with the germination space 101, which includes an air inlet 210, an air outlet 220, and a drip-capturing cavity 201 in communication between the air inlet 210 and the air outlet 220. The drip-capturing cavity 201 extends in a zigzag manner to capture liquid droplets in the water mist flow during the flow of the water mist flow. The drip-capturing cavity 201 is in communication with the germination space 101 through a backflow hole 213, and a backflow valve 212 with one-way sealing is fitted at the backflow hole 213.

[0036] In the exhaust type germinator 100 provided by the present application, the cover 2 is provided with an exhaust passage in communication with the germination space 101, which includes a drip-capturing cavity 201 extending in a zigzag manner. Liquid droplets in the water mist flow can be captured during the flow of the water mist flow through the drip-capturing cavity 201, thereby reducing the water content in the exhaust gas. The drip-capturing cavity 201 is in communication with the germination space 101 through a backflow hole 213, and a backflow valve 212 with one-way sealing is fitted at the backflow hole 213. This scheme allows the water mist flow to be directed and forced to pass through the material from bottom to top for infiltration, thereby improving the penetration effect of the water mist flow, and the liquid droplets in the water mist flow can be captured and backflow into the germination space 101, so that the humidity of the exhaust gas is relatively low.

[0037] In the present embodiment, the exhaust type malting machine 100 comprises a body 11, a water mist generator 15 for generating water mist, a water collecting member 3 and a material carrying member 4. The body 11 forms a misting chamber 110 suitable for storing water, and the water mist generator 15 is arranged in the misting chamber 110. The material carrying member 4 is used for carrying material, and is removably arranged on the body 11 from the top opening. The material carrying member 4 has a plurality of through holes allowing water mist to pass through but limiting the passage of material. The water collecting member 3 is removably arranged between the material carrying member 4 and the misting chamber 110 from the top opening. The water collecting member 3 has a mist outlet channel 312 for water mist to flow from the misting chamber 110 to the material carrying member 4, and a water collecting cavity 314 for collecting liquid dripping from the through holes of the material carrying member 4. The exhaust type malting machine 100 provided in the present application adopts a rice cooker type structure, so that water mist can be directed and forced to pass through the material from bottom to top to soak the material, improving the misting and humidifying effect. Moreover, waste water dripping from the material is collected by the water collecting member 3, avoiding the pollution of clean water in the misting chamber 110 affecting the misting effect.

[0038] Please refer to Figures 1 to 3 In the present embodiment, one end of the cover 2 is pivotally connected to the main body 1, and the other end is connected to the main body 1 by a buckle. An opening button is arranged on the cover 2, and when the opening button is operated, the buckle is released, and the cover 2 is pivoted to pop open relative to the main body 1. The pivot connection between the cover 2 and the main body 1 is a structure commonly used in rice cooker type products, which will not be described herein.

[0039] Please refer to Figure 4 and Figure 5 In the present embodiment, the main body 1 comprises a body 11, an outer shell surrounding the outside of the body 11, and electrical components required for the operation of the exhaust type malting machine 100. In the present embodiment, the electrical components include a circuit board arranged between the body 11 and the outer shell, a fan 5, a cable, and a water level sensor and a temperature sensor protruding into the body 11 for detecting water level.

[0040] Please refer to Figure 5 and Figure 8As shown, the gall bladder 11 is a container surrounded by a bottom wall and a side wall, which forms the atomization chamber 110. A mounting hole is formed in the middle of the bottom wall of the gall bladder 11 for mounting the water mist generator 15. When clean water is added into the atomization chamber 110, the clean water gathers at the bottom wall and contacts the water mist generator 15. The water mist generator 15 works to atomize the liquid water into water mist and fills the atomization chamber 110. The gall bladder 11 has a support flange 111, and the water collecting member 3 is supported on the support flange 111 and is at least partially accommodated in the gall bladder 11. In this embodiment, the support flange 111 is formed on the side wall of the gall bladder 11, and the position of the support flange 111 on the side wall is such that when the water collecting member 3 is supported on the support flange 111, there is a certain spacing between the bottom wall of the water collecting member 3 and the bottom wall of the gall bladder 11, which is used to accommodate water for atomization and as a space for water mist to fill.

[0041] In this embodiment, the water collecting member 3 is provided with a support step 322 which is supported above the support flange 111. Further, a sealing ring 6 is arranged between the support flange 111 and the water collecting member 3. Specifically, the lower surface of the support step 322 is provided with a mounting groove, and the sealing ring 6 is mounted in the mounting groove and protrudes from the mounting groove. When the water collecting member 3 is placed in the gall bladder 11, the support step 322 is supported on the support flange 111, and the sealing ring 6 is deformed to form a sealed connection between the support step 322 and the support flange 111. The arrangement of the sealing ring 6 can prevent water mist from passing through the gap between the water collecting member 3 and the gall bladder 11, so that the water mist needs to flow to the material carrying member 4 through the mist outlet passage 312 on the water collecting member 3, thereby improving the infiltration performance of the material in the material carrying member 4.

[0042] As shown in Figure 4 and Figure 5 , the water collecting member 3 includes a bottom wall, a side wall extending upward from the edge of the bottom wall, and a mist guide pipe 31 protruding upward from the bottom wall. The annular space formed by the bottom wall, the side wall, and the mist guide pipe 31 forms a water collecting cavity 314. The mist guide pipe 31 is a hollow pipe, and the hollow part inside the mist guide pipe 31 forms a mist outlet passage 312. The mist guide pipe 31 is provided with a mist outlet 310, and the water mist in the atomization chamber 110 flows to the material carrying member 4 through the mist outlet passage 312 from the mist outlet 310. Further, to prevent or reduce water droplets from the material carrying member 4 from dripping into the atomization chamber 110 through the mist outlet 310, the mist outlet 310 is at least partially arranged on the side of the mist guide pipe 31 to reduce the opening area in the horizontal direction. Specifically, the top of the mist guide pipe 31 has a top cover 311, and the mist outlet 310 is formed on the peripheral wall of the mist guide pipe 31 or at the connection between the peripheral wall and the top cover 311.

[0043] Please continue to refer to Figure 4 and Figure 5 As shown in Figs. 1 and 2, the load member 4 is a container for holding materials such as grains, and has a plurality of through holes allowing water mist to pass through but limiting the passage of materials. In this embodiment, the bottom wall of the load member 4 is woven with metal wires and has a plurality of mesh holes, and the load member 4 further has an annular peripheral wall extending from the edge of the bottom wall. A protruding ring is provided on the annular peripheral wall for connecting the bottom wall and simultaneously supporting the load member 4 in the water collecting member 3. In this embodiment, the load member 4 is supported and held in the water collecting member 3, as shown in Figs. 1 and 2, the upper end edge 321 of the water collecting member 3 is higher than the gall bladder 11, and the load member 4 is not higher than the water collecting member 3. The cover 2 comprises an inner cover 21 having a sealing member 211 on the edge, which sealing member 211 is in sealing cooperation with the upper end edge 321 of the water collecting member 3. In this way, the water mist is limited in the germination space 101, and the water mist flowing to the top of the germination space 101 is prevented from entering outside the gall bladder 11, so as to avoid the electrical components arranged between the gall bladder 11 and the outer shell from being damaged due to moisture. Figure 5

[0044] Please refer to Figure 5 and Figure 6 As shown in Figs. 1 and 2, the cover 2 is provided with an exhaust passage in communication with the germination space 101, which exhaust passage comprises an air inlet 210, an air outlet 220, and a drip catching cavity 201 arranged in a zigzag manner between the air inlet 210 and the air outlet 220. The drip catching cavity 201 is in communication with the germination space 101 through a backflow hole 213, and a backflow valve 212 is fitted at the backflow hole 213. The backflow valve 212 is a one-way valve having a resilient valve plate and a clamping column arranged at the middle of the resilient valve plate. The backflow valve 212 is connected to the inner cover 21 from bottom to top through the clamping column, and the resilient valve plate covers the backflow hole 213. When the water mist pushes the backflow valve 212 upward, the backflow valve 212 closes the backflow hole 213, and the water mist cannot directly enter the drip catching cavity 201 through the backflow hole 213. The water mist can only enter through the air inlet 210, and after passing through the zigzag drip catching cavity 201, the liquid water in the water mist is blocked and gathered in the drip catching cavity 201, and the gas is discharged from the air outlet 220. The liquid gathered in the drip catching cavity 201 pushes away the resilient valve plate of the backflow valve 212 under the action of gravity and drops back to the load member 4. The exhaust passage arranged in this way can reduce the loss of water mist, and at the same time, can avoid the formation of liquid gathering at the air outlet 220.
