The embodiments of the utility model will be described in detail below.

[0046] Embodiment one

[0047] Figure 1 A structural schematic diagram of the humidity generating device provided in the embodiments of the utility model.

[0048] Referring to Figure 1 The humidity generating device provided in the embodiments of the utility model is applied to a fermentation tank and comprises an inner water tank 1 and an outer water tank 4. The inner water tank 1 is provided with an atomizer assembly 2 and a water level switch assembly 3. Water in the inner water tank 1 forms water mist under the action of the atomizer assembly 2, and the water mist flows to the fermentation tank for fermentation of food materials. The water level switch assembly 3 is used for detecting the water quantity in the inner water tank 1.

[0049] The outer water tank 4 is connected with the inner water tank 1 through a water supplement pipeline, and the water supplement pipeline is provided with a water pump 5. In the embodiments, the fermentation tank refers to a device for making food materials fully ferment and expand under certain temperature and humidity to realize fermentation of the food materials.

[0050] It can be understood that the inner water tank 1 and the outer water tank 4 are in a relative relationship, the inner water tank 1 is inside and the outer water tank 4 is outside, but the inner water tank 1 and the outer water tank 4 are both arranged in the fermentation tank, and the specific positional relationship is described below.

[0051] When the water level switch assembly 3 detects that the water quantity in the inner water tank 1 is lower than the set value, it indicates that the inner water tank 1 is short of water, at this time the water pump 5 is actuated, and the water in the outer water tank 4 enters the inner water tank 1 through the water supplement pipeline to supplement the water in the inner water tank 1.

[0052] The working principle of the humidity generating device provided by the embodiment of the utility model is that the water in the inner water tank 1 forms water mist under the action of the atomizer assembly 2, the water mist flows to the fermentation tank for fermentation of food materials, when the water level switch assembly 3 detects that the water quantity in the inner water tank 1 is lower than the set value, it indicates that the inner water tank 1 is short of water, at this time the water pump 5 is actuated, and the water in the outer water tank 4 enters the inner water tank 1 through the water supplement pipeline to automatically supplement the water in the inner water tank 1.

[0053] As can be seen from the above, the humidity generating device provided by the embodiment of the utility model is applied to a fermentation tank, comprising an inner water tank 1, the inner water tank 1 is provided with an atomizer assembly 2 and a water level switch assembly 3, the water in the inner water tank 1 forms water mist under the action of the atomizer assembly 2, the water mist flows to the fermentation tank for fermentation of food materials, and the water level switch assembly 3 is used for detecting the water quantity in the inner water tank 1. An outer water tank 4, the outer water tank 4 is connected with the inner water tank 1 through a water supplement pipeline, and the water supplement pipeline is provided with a water pump 5; when the water level switch assembly 3 detects that the water quantity in the inner water tank 1 is lower than the set value, the water pump 5 is actuated, and the water in the outer water tank 4 enters the inner water tank 1 through the water supplement pipeline under the drive of the water pump 5. Therefore, by arranging the water level switch assembly 3 in the inner water tank 1 and connecting the outer water tank 4 with the inner water tank 1 through the water supplement pipeline and arranging the water pump 5 in the water supplement pipeline, when the water level switch assembly 3 detects that the water quantity in the inner water tank 1 is lower than the set value, the water pump 5 is actuated, and the water in the outer water tank 4 enters the inner water tank 1 through the water supplement pipeline under the drive of the water pump 5 to automatically supplement the water in the inner water tank 1, manual water supplement is not needed, automatic water supplement is realized, the problem that the fermentation tank cannot reach the water level range of the atomizer through manual water addition is solved, and the normal fermentation effect of the fermentation tank is ensured.

[0054] In addition, the water pump 5 is actuated only when the water level switch assembly 3 detects that the water quantity in the inner water tank 1 is lower than the set value, therefore, accurate water level control can be realized, the situation of adding too much water or too little water is avoided, and the water quantity in the inner water tank 1 can be maintained in a range suitable for water mist formation, and the atomization effect is good.

[0055] Meanwhile, the inner water tank 1 is supplied with water by the outer water tank 4 arranged in the fermentation box, without external water source, higher integration, and more convenient operation. In addition, the user can use it in the installation scene where it is inconvenient to connect the external water, and the water capacity of the humidity generating device is expanded by the arranged outer water tank 4 without connecting the external water, without frequent water supply to the water tank of the humidity generating device.

[0056] Continuing to refer to Figure 1 , the water level switch assembly 3 can include a floating ball, a magnetic switch 31 and a first support 32.

[0057] The first support 32 is fixedly installed on the side wall of the inner water tank 1, the magnetic switch 31 is fixedly installed on the first support 32, the floating ball is connected with the shell of the magnetic switch 31 through a pull rope, and the floating ball floats on the water surface of the inner water tank 1, and a magnet is arranged in the floating ball. Among them, the fixed connection mode can be screw connection, of course, other common connection modes such as welding, pin connection, etc. can also be used.

[0058] When the floating ball rises, the magnet in the floating ball rises with the floating ball and approaches the magnetic switch 31, the magnet generates a magnetic field, triggers the contact in the magnetic switch to close, at this time, the magnetic switch outputs an opening signal, indicating that the inner water tank 1 is not short of water, and water is not needed. On the contrary, when the floating ball sinks with the water level below the predetermined water level, the magnet moves away from the magnetic switch 31, the magnetic field around the magnetic switch 31 disappears, the contact in the magnetic switch 31 is separated, at this time, the magnetic switch 31 is closed, and outputs a closing signal, indicating that the inner water tank 1 is short of water, triggering the water pump 5 to act to supply water. Among them, the predetermined water level can be set according to actual needs, which is not limited here, for example, it can be 20mm below the water level of the inner water tank 1 after being normally filled with water.

[0059] Therefore, by arranging a magnet in the floating ball and connecting the floating ball with the shell of the magnetic switch 31 through a pull rope, when the floating ball sinks with the water level below the predetermined water level, the magnet moves away from the magnetic switch 31, the magnetic field around the magnetic switch 31 disappears, the contact in the magnetic switch 31 is separated, the magnetic switch 31 is closed, and outputs a closing signal to trigger the water pump 5 to act to supply water.

[0060] Continuing to refer to Figure 1 , the atomizer assembly 2 includes an atomizer 21 and a second support 22, the second support 22 is arranged on the bottom wall of the inner water tank 1, and the atomizer 21 is fixedly connected with the second support 22. Among them, the fixed connection mode can be screw connection, of course, other common connection modes such as welding, pin connection, etc. can also be used.

[0061] Since the second support 22 is arranged on the bottom wall of the inner water tank 1, and the atomizer 21 is fixedly connected with the second support 22, therefore, the atomizer 21 must be below the water surface of the inner water tank 1, in order to act on the water in the inner water tank 1 to form water mist.

[0062] Therefore, by arranging the second support 22 at the bottom wall of the inner water tank 1, and connecting and fixing the atomizer 21 with the second support 22 in a manner that the atomizer 21 acts on the water in the inner water tank 1 to form water mist to realize fermentation.

[0063] Continuing to refer to Figure 1 The humidity generating device provided by the embodiment of the present application can further include a heating element 6 and a flow guiding element 7. Along the flow direction of the water mist, the heating element 6 is arranged upstream of the inner water tank 1, and the flow guiding element 7 is arranged downstream of the inner water tank 1. Referring to the direction shown in the figure, the flow direction of the water mist is from left to right.

[0064] This is because providing water mist with a certain temperature into the fermentation tank is more conducive to improving the fermentation effect of the food materials, and therefore the heating element 6 is designed and arranged upstream of the inner water tank 1, and the water mist is formed in the inner water tank 1, that is, the heating element 6 is arranged upstream of the water mist, so that the air heated by the heating element 6 flows through the water mist to heat it, and the generated water mist can be uniformly and sufficiently heated. The heated water mist needs to flow to the fermentation tank, and the flow guiding element 7 is arranged downstream of the inner water tank 1, so that the water mist that is sufficiently heated can be provided into the fermentation tank.

[0065] Therefore, by arranging the heating element 6 upstream of the inner water tank 1 and the flow guiding element 7 downstream of the inner water tank 1 in this manner, the heating element 6 can heat the water mist formed in the inner water tank 1 under the action of the atomizer assembly 2, and then the heated water mist flows to the fermentation tank through the flow guiding of the flow guiding element 7. The heating element 6, the inner water tank 1 and the flow guiding element 7 are arranged in sequence along the flow direction of the water mist, which can reduce the space occupied in the width direction, and especially for a long and flat fermentation tank, this is more conducive to adapting the humidity generating device of the present embodiment to the empty space of the fermentation tank, avoiding increasing the design difficulty of the whole machine of the fermentation tank.

[0066] Continuing to refer to Figure 1 The capacity of the outer water tank 4 is greater than that of the inner water tank 1, and along the flow direction of the water mist, the outer water tank 4 is arranged upstream of the heating element 6. In this way, the outer water tank 4, the heating element 6, the inner water tank 1 and the flow guiding element 7 are arranged in sequence along the flow direction of the water mist, which can reduce the space occupied in the width direction, and is conducive to adapting the space utilization of the fermentation tank. Moreover, the capacity of the outer water tank 4 is designed to be greater than that of the inner water tank 1, which can improve the water capacity of the humidity generating device of the present embodiment and prolong the use time of single water injection. The capacity of the outer water tank 4 can be adjusted according to actual space limitations, which is not specifically limited here, for example, the capacity of the outer water tank 4 is more than 3 times the capacity of the inner water tank 1.

[0067] Therefore, by arranging the outer water tank 4 upstream of the heating element 6, the water in the outer water tank 4 is facilitated to flow to the inner water tank 1, and by arranging the capacity of the outer water tank 4 to be greater than the capacity of the inner water tank 1, the inner water tank 1 is facilitated to be replenished by the outer water tank 4, without the need of an external water source, with higher integration and more convenient operation.

[0068] With reference to the above Figure 1 , the humidity generating device provided by the embodiment of the present application can further include an air duct box 8, the heating element 6, the inner water tank 1 and the drainage element 7 are arranged in the air duct box 8, and the outer water tank 4 is arranged outside the air duct box 8. Since the heating element 6, the inner water tank 1 and the drainage element 7 are arranged in the air duct box 8, the heating element 6 can cyclically heat the water mist in the air duct box 8, and the heating is more sufficient, and then the heated water mist is guided to the fermentation tank by the drainage of the drainage element 7. Arranging the outer water tank 4 outside the air duct box 8 facilitates water replenishment for the outer water tank 4.

[0069] Therefore, by arranging the heating element 6, the inner water tank 1 and the drainage element 7 in the air duct box 8, the heating element 6 can cyclically heat the water mist in the air duct box 8, and the heating is more sufficient, and then the heated water mist is guided to the fermentation tank by the drainage of the drainage element 7, which is more conducive to fermentation, and arranging the outer water tank 4 outside the air duct box 8 facilitates water replenishment for the outer water tank 4, improving the convenience of operation.

[0070] The heating element 6 can be an air heating pipe, of course, the heating element 6 can also be selected from other types of electric heating rods, etc., which are not limited here. The air heating pipe 6 is arranged at the upper portion of the air duct box 8, which is conducive to heating the water mist in the air duct box 8. For example, the air heating pipe 6 is arranged at the upper portion of the front wall of the air duct box 8. The drainage element 7 can be a cross-flow fan, of course, the drainage element 7 can also be selected from other types of fans or motors, etc., which are not limited here.

[0071] Therefore, by arranging the heating element 6 as an air heating pipe and arranging the air heating pipe 6 at the upper portion of the air duct box 8, the air heating pipe can heat the water mist rising in the air duct box 8, and the heating is more sufficient, and by arranging the drainage element 7 as a cross-flow fan, the blown wind is more concentrated, the drainage is more focused and not divergent, and the efficiency is improved.

[0072] With reference to the above Figure 1 , the bottom of the inner water tank 1 is further provided with a drain pipe 9 extending to the outside of the fermentation tank. Therefore, by arranging the drain pipe 9 extending to the outside of the fermentation tank at the bottom of the inner water tank 1, the water in the inner water tank 1 is facilitated to be drained without the need of disassembly, and the operation is convenient.
