For example, the existing constant-humidity box has only a humidifying function and has no dehumidifying function, the humidifying mode and the air duct are unreasonable in design, so that fluctuation of the humidifying effect is large, in addition, even if humidification is stopped, residual moisture in the equipment system still can enable the humidity of the constant-humidity box to continuously rise in a short time, and the upper limit of the humidity of the constant-humidity box is uncontrollable and the humidity control precision is low.

The constant humidity cabinet adjusts the humidity of the humidity control cavity by utilizing the dehumidification module and the humidification module.

Because dehumidification module and humidification module all connect the accuse wet chamber through accuse wet pipeline and valve I to connect the external world through ventilation line and valve II, to any one of dehumidification module and humidification module, consequently, governing valve I can control the on-off state in accuse wet pipeline and accuse wet chamber, governing valve II can control the on-off state of ventilation line and external world.

Referring to fig. 1 to 4, the present utility model provides a constant humidity cabinet, which comprises a humidity control chamber 1, a dehumidification module 2, a humidification module 3 and a cabinet main switch; in the constant humidity cabinet, the dehumidifying module 2 and the humidifying module 3 are synchronously started and stopped along with a cabinet main switch, in other words, when the constant humidity cabinet is started through the cabinet main switch, the dehumidifying module 2 and the humidifying module 3 are both started and maintain the running state, and when the constant humidity cabinet is closed through the cabinet main switch, the dehumidifying module 2 and the humidifying module 3 are turned off along with the constant humidity cabinet; in the constant humidity cabinet, a humidity control pipeline and a ventilation pipeline are arranged on the dehumidification module 2, a humidity control pipeline and a ventilation pipeline are also arranged on the humidification module 3, the dehumidification module 2 is connected with the humidity control cavity 1 through the corresponding humidity control pipeline and a valve I and is connected with the outside through the corresponding ventilation pipeline and a valve II, and similarly, the humidification module 3 is connected with the humidity control cavity 1 through the corresponding humidity control pipeline and a valve I and is connected with the outside through the corresponding ventilation pipeline and a valve II; wherein, valve I and valve II of dehumidification module 2 interlock, and valve I and valve II of humidification module 3 also interlock.

The humidity control chamber 11 may be regarded as a working chamber of the constant humidity cabinet, and the workpiece is placed in the humidity control chamber 11, in other words, the humidity control chamber 11 may provide a working environment with constant humidity for the workpiece therein. In the constant humidity cabinet provided by the utility model, the dehumidification module 22 and the humidification module 33 are both communicated with the humidity control cavity 11, obviously, the dehumidification module 22 is used for dehumidifying the humidity control cavity 11, so that the humidity of the humidity control cavity 11 can be reduced, and the humidification module 33 is used for humidifying the humidity control cavity 11, so that the humidity of the humidity control cavity 11 can be improved.

In the constant humidity cabinet provided by the utility model, the linkage interlocking of the valve I and the valve II of the dehumidification module 2 means that the valve II is automatically closed when the valve I of the dehumidification module 2 is opened, and conversely, the valve I is automatically closed when the valve II of the dehumidification module 2 is opened; similarly, the valve I and the valve II of the humidification module 3 are also interlocked, which means that the valve II is automatically closed when the valve I of the humidification module 3 is opened, and conversely, the valve I is automatically closed when the valve II of the humidification module 3 is opened.

In the constant humidity cabinet provided by the utility model, the dehumidification module 2 and the humidification module 3 can continuously run when the cabinet main switch is opened, so that the dehumidification module 2 is always in an initial working state, and the humidification module 3 is also always in a humidification state. The foregoing dehumidification module 2 and the humidification module 3 are both connected with the humidity control cavity 1 through respective corresponding humidity control pipelines and valves I, if the valves I are in a closed state, the dehumidification effect of the dehumidification module 2 is not applied to the humidity control cavity 1, and the humidification effect of the humidification module 3 is not applied to the humidity control cavity 1, otherwise, if the valves I are in an open state, the dehumidification module 2 can dehumidify the humidity control cavity 1 through the corresponding humidity control pipelines and valves I, and the humidification effect of the humidification module 3 can also humidify the humidity control cavity 1 through the corresponding humidity control pipelines and valves I. Of course, in order to ensure that the dehumidification module 2 and the humidification module 3 can continuously and normally operate for a long time, if any one of the dehumidification module 2 and the humidification module 3 does not operate the humidity control cavity 1 through the humidity control pipeline and the valve I, ventilation with the outside through the ventilation pipeline and the valve II is needed, and the air passage where any one of the dehumidification module 2 and the humidification module 3 is located is ensured to be unobstructed.

As described above, in the present utility model, the valve I and the valve II of either one of the dehumidification module 2 and the humidification module 3 are interlocked in a linkage manner, the valve II is opened once the valve I is closed, the valve I blocks the humidity control pipe and the humidity control chamber 1, and the valve II communicates the ventilation pipe and the outside, and also the valve I is opened once the valve II is closed, the valve II blocks the ventilation pipe and the outside, and the valve I communicates the humidity control pipe and the humidity control chamber 1, thereby ensuring that the dehumidification module 2 and the humidification module 3 can continuously and normally operate for a long time.

Therefore, in the constant humidity cabinet provided by the utility model, in the state that the dehumidification module 2 and the humidification module 3 continuously run, the humidity adjusting effect of any one of the dehumidification module 2 and the humidification module 3 on the humidity control cavity 1 can be quickly and sensitively adjusted through the valve I and the valve II, for example, when the humidity control cavity 1 needs to be humidified, the valve I of the humidification module 3 is opened and the valve II of the humidification module 3 is closed, so that the humidification module 3 is communicated with the humidity control cavity 1, and meanwhile, the valve II of the dehumidification module 2 is opened and the valve I of the humidification module 3 is closed, so that the dehumidification module 2 is communicated with the outside; when the humidity control cavity 1 needs to be dehumidified, the valve I of the dehumidification module 2 is opened, the valve II of the dehumidification module 2 is closed, the dehumidification module 2 is communicated with the humidity control cavity 1, and meanwhile, the valve II of the humidification module 3 is opened, the valve I of the humidification module 3 is closed, and the humidification module 3 is communicated with the outside.

Compared with the common humidity control technology, the constant humidity cabinet provided by the utility model does not adjust the humidity control effect on the humidity control cavity 1 by frequently starting and stopping the dehumidification module 2 and the humidification module 3, but adjusts the communication state of any one of the dehumidification module 2 and the humidification module 3 and the humidity control cavity 1 by adjusting the valve elements of the valve I and the valve II, so as to change the humidity adjustment effect of any one of the dehumidification module 2 and the humidification module 3 on the humidity control cavity 1. The valves I and II can respond to the dehumidification signals rapidly and sensitively, when the humidity control cavity 1 needs to be humidified, the humidification module 3 can instantly introduce water vapor into the humidity control cavity 1, when the humidity control cavity 1 does not need to be humidified, the humidification module 3 can instantly stop introducing the water vapor into the humidity control cavity 1, when the humidity control cavity 1 needs to be dehumidified, the dehumidification module 2 can instantly dehumidify the humidity control cavity 1, and when the humidity control cavity 1 does not need to be dehumidified, the dehumidification module 2 can instantly stop dehumidifying the humidity control cavity 1.

In summary, the constant humidity cabinet provided by the utility model can improve the response speed of humidification/dehumidification actions, and avoid the influence of the dehumidification module 2 and the humidification module 3 on humidity control precision due to action delay, so that the humidity can be accurately, stably and rapidly controlled, and the constant humidity cabinet is particularly suitable for humidity control in the pretreatment process of micro-liter and nano-liter micro-biological samples and the sample application process before mass spectrometry.

The constant humidity cabinet provided by the utility model is further described below with reference to the accompanying drawings and the embodiments.

Referring to fig. 3 to 6, in some embodiments, the dehumidification module 2 and the humidification module 3 may both be connected to the humidity control chamber 1 and the outside through a three-way pipe, for example, a three-way pipe I8 may be disposed between the dehumidification module 2 and the humidity control chamber 1, the three-way pipe I8 includes three branch pipes, two branch pipes are a humidity control pipe and a ventilation pipe respectively, another branch pipe is connected to the dehumidification module 2, similarly, a three-way pipe II9 may be disposed between the humidification module 3 and the humidity control chamber 1, the three-way pipe II9 also includes three branch pipes, two branch pipes are a humidity control pipe and a ventilation pipe respectively, and another branch pipe is connected to the humidification module 3.

The three branch pipes of the three-way pipe I8 are respectively connected with the dehumidification module 2, the humidity control cavity 1 and the outside, so that the three-way pipe I8 can be also regarded as being arranged among the dehumidification module 2, the humidity control cavity 1 and the outside. For the three-way pipe I8, the branch pipe connected with the humidity control cavity 1 can be regarded as a humidity control pipeline, the humidity control pipeline is communicated with the humidity control cavity 1 through the valve I, the branch pipe connected with the outside can be regarded as a ventilation pipeline, and the ventilation pipeline is communicated with the outside through the valve II. The valve I may be disposed in the humidity control pipe, or may be disposed in a connection between the humidity control pipe and the humidity control chamber 1, and the valve II may be disposed in the ventilation pipe, or may be regarded as a connection between the ventilation pipe and the outside.

Similarly, the three branch pipes of the three-way pipe II9 are respectively connected with the humidifying module 3, the humidity control cavity 1 and the outside, so that the three-way pipe II9 can be also regarded as being arranged among the humidifying module 3, the humidity control cavity 1 and the outside. One branch pipe of the three-way pipe II9 can be regarded as a humidity control pipeline, the humidity control pipeline is communicated with the humidity control cavity 1 through the valve I, the other branch pipe of the three-way pipe II9 can be regarded as a ventilation pipeline, and the ventilation pipeline is communicated with the outside through the valve II.

In the above embodiment, the application of the three-way pipe simplifies the pipeline structure between the humidifying module 3 and the dehumidifying module 2, and between the humidity control cavity 1 and the outside, which is beneficial to the humidifying module 3 and the dehumidifying module 2 to quickly adjust the operation mode of the humidity control cavity 1, and is also beneficial to the positioning and installation of a plurality of valve members in the constant humidity cabinet.

Referring to fig. 2 and 4, in some embodiments, the humidification module 3 may include an atomizing hood 31, a fan 32, an atomizer 33, and a water storage mesh 34; the atomizing nozzle 33 is positioned in the atomizing cover 31, and the fan 32 and the water storage net cloth 34 are respectively arranged at the openings of the two opposite sides of the atomizing cover 31; the atomizing nozzle 33 faces the water storage net cloth 34 and faces away from the humidity control cavity 1, the fan 32 is positioned between the humidifying module 3 and the corresponding humidity control pipeline, and the fan 32 can drive water mist to flow towards the humidity control cavity 1 when running, so that the humidifying module 3 humidifies the humidity control cavity 1.

The two sides of the atomizing cover 31 are respectively provided with an opening and are respectively provided with a fan 32 and a water storage net cloth 34, and any one of the fan 32 and the water storage net cloth 34 can be arranged in the atomizing cover 31 and is close to the opening, and can also be arranged outside the atomizing cover 31 and is close to the opening. The atomization cap 31 can provide a space for the fan 32 and the atomization nozzle 33 to flow water vapor, which is beneficial to stabilizing the air flow and the water mist content in the atomization cap 31.

The atomizing nozzle 33 is directed toward the water storage mesh 34, so that liquid water can be atomized and sprayed toward the water storage mesh 34, and the water storage mesh 34 can be used for holding water mist as much as possible, so that more water mist is restrained in the atomizing cover 31. Since the atomizer 33 faces away from the humidity control chamber 1, and the fan 32 is used for driving the water mist in the atomizer cover 31 to flow towards the humidity control chamber 1, it can be seen that the atomizer 33 does not directly spray the water mist towards the humidity control chamber 1, but sends the water mist into the humidity control chamber 1 through the fan 32, for example, the humidity control chamber 1 is located above the atomizer 33, the atomizer 33 sprays the water mist downwards, after the fan 32 is started, a drainage effect is generated on the water mist in the atomizer cover 31, and the water mist in the atomizer cover 31 is guided to move upwards to enter the humidity control chamber 1.

The humidity of the humidity control chamber 1 can be accurately and stably increased by the humidifying module 3, which is not only because the atomizing cover 31 and the water storage mesh cloth 34 can provide a non-closed space which can smoothly flow through air supply and is favorable for accumulating water mist, and is favorable for the fan 32 to generate stable air flow and carry the water mist in the atomizing cover 31 to enter the humidity control chamber 1, but also because the atomizing nozzle 33 does not directly spray the water mist towards the humidity control chamber 1, the water mist generated by the atomizing nozzle 33 is continuously and stably sent into the humidity control chamber 1 through the fan 32, the action response precision of the water mist entering the humidity control chamber 1 during humidification can be improved, and the quantity of the water mist entering the humidity control chamber 1 can be conveniently adjusted by adjusting the rotating speed of the fan 32.

The humidification module 3 controls the water mist to enter the humidity control cavity 1 by using the running state of the fan 32. Compared with the control of the spraying amount of the atomizing nozzle 33 and the spraying amount of the water mist sprayed into the humidity control cavity 1, the action response degree of the fan 32 when the running state of the fan 32 is used for controlling the water mist to enter the humidity control cavity 1 can be more timely and sensitive, and in addition, a large amount of water mist is accumulated in the atomizing cover 31 for a long time, compared with the direct adjustment of the spraying amount of the atomizing nozzle 33, the adjustment of the amount of the water mist entering the humidity control cavity 1 by adjusting the rotating speed of the fan 32 is easier and has higher accuracy.

Generally, the atomizing cover 31 is provided with a hollowed-out baffle at the position where the water storage mesh 34 is located, and the water storage mesh 34 is flatly hung on the opening of the atomizing cover 31 through the baffle, for example, the water storage mesh 34 can be clamped between the atomizing cover 31 and the baffle.

Based on the above embodiment, the atomizing cover 31 may further include a closing plate surrounding the periphery of the atomizing cover 31, and as can be seen from the foregoing, two opposite sides of the atomizing cover 31 are respectively provided with openings, and as can be seen from the foregoing, the openings are provided at two ends of the atomizing cover 31, and accordingly, the fan 32 and the water storage mesh 34 are mounted at two ends of the atomizing cover 31, for example, the fan 32 is mounted at the opening of the top of the atomizing cover 31, and the water storage mesh 34 is stretched at the opening of the bottom of the atomizing cover 31. In this embodiment, the fan 32 drives the water mist in the atomization cover 31 to flow toward the top of the atomization cover 31, so that the water mist flows from the top of the atomization cover 31 to the humidity control cavity 1; the retaining screen cloth 34 is located the bottom of atomizing cover 31, and atomizer 33 is towards the bottom of atomizing cover 31, and atomizing cover 31 combines retaining screen cloth 34 can restrict the vast majority water smoke that atomizer 33 produced in atomizing cover 31, is favorable to fan 32 drive atomizing cover 31 in the water smoke entering accuse wet chamber 1.

On the basis of the embodiment, the constant humidity cabinet further comprises a water tank 4, and the atomization cover 31 is arranged in the water tank 4 and is suspended above the liquid level of the water tank 4; meanwhile, a water pumping pipe 5 is arranged between the water tank 4 and the atomizing nozzle 33, and water in the water tank 4 enters the atomizing nozzle 33 through the water pumping pipe 5.

The water tank 4 supplies water to the atomizing head 33, and the atomizing head 33 sprays water mist into the atomizing cover 31. In addition, a water pump is usually arranged between the water tank 4 and the atomizing nozzle 33, and water in the water tank 4 enters the atomizing nozzle 33 through the water suction pipe 5 and the water pump, so that atomized water drops and water mist are formed under the atomization action of the atomizing nozzle 33.

When the concentration of the water mist in the atomization cover 31 continuously rises and reaches a certain degree, the water storage function of the water storage net cloth 34 reaches the limit, the water mist in the atomization cover 31 continuously flows to the water tank 4, so that the concentration of the water mist in the atomization cover 31 can be stabilized, and water can be recovered through the water tank 4.

Referring to fig. 4, the humidifying module 3 further includes a first humidifying channel 61 and a second humidifying channel 62 provided between the atomizing cover 31 and the humidity control chamber 1; the atomization cap 31, the first humidifying channel 61, the second humidifying channel 62 and the humidity control chamber 1 are sequentially communicated; the fan 32 is disposed in the first humidification passage 61, and the rotation diameter of the fan 32 and the inner diameter of the first humidification passage 61 are both larger than the inner diameter of the second humidification passage 62. In this embodiment, the fan 32 is disposed in the first humidification passage 61, so that the rotation diameter of the fan 32 does not exceed the inner diameter of the first humidification passage 61, and in general, the rotation diameter of the fan 32 is slightly smaller than the inner diameter of the first humidification passage 61, and both the rotation diameter of the fan 32 and the inner diameter of the first humidification passage 61 are larger than the inner diameter of the second humidification passage 62, and it can be seen that the inner diameter of the first humidification passage 61 is larger than the rotation diameter of the fan 32 and the rotation diameter of the fan 32 is larger than the inner diameter of the second humidification passage 62.

The inner diameter of the second humidification passage 62 is smaller than the inner diameter of the first humidification passage 61 and smaller than the rotation diameter of the fan 32, so that the fan 32 is of a necessary structure when water mist flows towards the humidity control cavity 1, and the humidity adjustment precision of the fan 32 to the humidity control cavity 1 is guaranteed.

The humidification module 3 is connected with the humidification port 12 of the humidity control cavity 1, and the humidification module 3 is connected with the humidification port 12 of the humidity control cavity 1 through a corresponding humidity control pipeline. For example, a three-way pipe II9 is arranged between the humidifying module 3 and the humidity control cavity 1, one branch of the three-way pipe II9 is used as a humidity control pipeline, and the humidity control pipeline is arranged between the humidifying module 3 and the humidity control port and is used for connecting the humidifying module 3 and the humidity control cavity 1.

The connection of the dehumidification module 2 with the dehumidification ports 13 means that the dehumidification module 2 is connected with two dehumidification ports 13 of the humidity control cavity 1 through corresponding humidity control pipelines. For example, two three-way pipes I8 are arranged between the dehumidification module 2 and the humidity control cavity 1, one branch of any one three-way pipe I8 is used as a humidity control pipeline, and meanwhile, the dehumidification module 2 is provided with a dehumidification inlet 22 and a dehumidification outlet 23; the dehumidifying inlet 22 and the dehumidifying outlet 23 of the dehumidifying module 2 correspond to the two dehumidifying ports 13 of the humidity control chamber 1 respectively, a three-way pipe I8 is arranged between the dehumidifying inlet 22 and the corresponding dehumidifying port 13, and a three-way pipe I8 is also arranged between the dehumidifying outlet 23 and the corresponding dehumidifying port 13.

Referring to fig. 2 and 7, on the basis of the above embodiment, the constant humidity cabinet provided by the present utility model further includes a humidity control cabinet; the humidity control cavity 1 is positioned in the humidity control shell; the humidity control housing may include a partition plate 11 and a housing door 14, both of which are respectively disposed at both sides of the humidity control chamber 1, for example, the partition plate 11 may be disposed at the bottom of the humidity control chamber 1, and the housing door 14 may be disposed at the front side of the humidity control chamber 1; the humidifying port 12 and the two dehumidifying ports 13 of the humidity control chamber 1 are both provided in the partition 11.

The cabinet door 14 is used for opening and closing the humidity control chamber 1. When an operator needs to take and place a workpiece from the humidity control cavity 1, the machine box door 14 can be opened, and after the operator finishes the operation of taking and placing the workpiece, the machine box door 14 needs to be closed.

The partition 11 and the cabinet door 14 are separately disposed at both sides of the humidity control chamber 1, and obviously, the humidifying port 12 and the dehumidifying port 13 disposed at the partition 11 are naturally also separately disposed at both sides of the humidity control chamber 1 with the cabinet door 14. The humidifying port 12 and the dehumidifying port 13 are separated from the case door 14 as far as possible, so that the influence of the headstock gear door 14 on the humidifying port 12 and the dehumidifying port 13 can be reduced, especially the influence of the frequent headstock gear door 14 on the humidifying port 12 is reduced, and the humidifying effect of the humidifying module 3 on the humidity control cavity 1 is stabilized.

Referring to fig. 2 and 6, in some embodiments, the dehumidification module 2 may include a dehumidification chassis 21, a dehumidification fan, and a water chiller; the dehumidifying fan is arranged in the dehumidifier cabinet 21 and provides power for realizing gas circulation between the humidity control cavity 1 and the dehumidifier cabinet 21; the dehumidifier case 21 is provided with a dehumidification inlet 22, a dehumidification outlet 23 and a dehumidification outlet, wherein the dehumidification inlet 22 and the dehumidification outlet 23 are both connected to the humidity control cavity 1, a structural foundation is provided for realizing gas circulation between the humidity control cavity 1 and the dehumidifier case 21, and the dehumidification outlet discharges moisture in the dehumidifier case 21 through hot air. The dehumidification inlet 22 and the dehumidification outlet 23 are both connected to the humidity control cavity 1, which means that any one of the dehumidification inlet 22 and the dehumidification outlet 23 is connected with the humidity control pipeline and the ventilation pipeline, the dehumidification inlet 22 is connected with the humidity control cavity 1 through the corresponding humidity control pipeline, in other words, the dehumidification outlet 23 is connected with the humidity control cavity 1 through the corresponding humidity control pipeline, in other words, the dehumidification inlet 22 and the dehumidification outlet 23 of the dehumidification module 2 are respectively connected with the humidity control cavity 1 through two humidity control pipelines, and the two humidity control pipelines can be provided with the cold water drain 7, so that the temperature of the humidity control pipeline and the water vapor in the humidity control pipeline can be reduced, the temperature rise phenomenon caused by the operation of the dehumidification module 2 is weakened, the performance of the dehumidification module 2 is guaranteed, and the temperature of the constant humidity cabinet is stabilized.

In the operation process of the dehumidification module 2, when the dehumidification module 2 is communicated with the humidity control cavity 1, the dehumidification module 2 and the humidity control cavity 1 realize gas circulation, and after the air with high humidity in the humidity control cavity 1 enters the dehumidification module 2, the moisture is discharged through a moisture discharge port.

In addition, in some embodiments, the constant humidity cabinet provided by the utility model further comprises a humidity controller and a humidity sensor arranged in the humidity control cavity 1; the humidity sensor, the valve I and the valve II are all coupled to the humidity controller, and the humidity controller can control the on-off states of the valve I and the valve II according to the detection result of the humidity sensor, so as to adjust the operation states of the humidification module 3 and the dehumidification module 2 on the humidity control cavity 1, for example, when the humidity control cavity 1 needs to be increased, the humidification module 3 is made to humidify the humidity control cavity 1 and the dehumidification module 2 is made to stop dehumidifying the humidity control cavity 1, and when the humidity control cavity 1 needs to be decreased, the dehumidification module 2 is made to dehumidify the humidity control cavity 1 and the humidification module 3 is made to stop humidifying the humidity control cavity 1. The specific embodiment of the humidity control device for controlling the temperature of the humidity control chamber 11 is relatively common, and thus, the specific structure and functional principle of the humidity control device can be referred to the related design of the prior art.

When the humidity of the humidity control cavity 1 needs to be accurately controlled, if the humidity of the humidity control cavity 1 is lower than the lower limit of a set humidity interval, the humidifying module 3 and the humidity control cavity 1 can be connected, the dehumidifying module 2 and the humidity control cavity 1 can be disconnected, the humidifying module 3 humidifies the humidity control cavity 1, and the humidity of the humidity control cavity 1 is improved; if the humidity of the humidity control cavity 1 is within the set humidity range, the humidifying module 3 and the dehumidifying module 2 are disconnected from the humidity control cavity 1, and the humidity is neither humidified nor dehumidified at the moment; if the humidity of the humidity control cavity 1 is higher than the upper limit of the set humidity interval, the dehumidification module 2 and the humidity control cavity 1 can be connected, the humidification module 3 and the humidity control cavity 1 can be disconnected, the dehumidification module 2 dehumidifies the humidity control cavity 1, and the humidity of the humidity control cavity 1 is reduced. Obviously, the humidification module 3 and the dehumidification module 2 will not always be in communication with the humidity control chamber 1 at the same time.

For example, after the operator opens the door 14 and inserts the workpiece into the humidity control chamber 1, the working area of the humidity control chamber 1 may be set, such as setting the working area of the humidity control chamber 1 to 39% -41%, that is, the set humidity area mentioned above refers to 39% -41%. In general, the humidity of the humidity control chamber 1 is consistent with the humidity of the external environment, for example, the humidity of the external environment is 60%, the humidity of the humidity control chamber 1 is 60% at the beginning, and the dehumidification module 2 automatically dehumidifies the humidity control chamber 1 under the control of the humidity controller, so that the humidity of the humidity control chamber 1 is gradually reduced to 41%. If the humidity of the humidity control chamber 1 drops below 39% due to the continuous operation of the workpiece in the humidity control chamber 1, the humidifying module 3 automatically humidifies the humidity control chamber 1 under the control of the humidity controller, so that the humidity of the humidity control chamber 1 gradually rises and returns to the set humidity interval.

In addition, the constant humidity cabinet can also realize temperature regulation through a temperature regulating device, so that the humidity control cavity 11 can maintain accurate and constant temperature, in other words, the humidity control cavity 1 can also be set as the temperature control humidity control cavity 1.

The humidifying module 3 adopted by the utility model reasonably distributes the components such as the atomizing cover 31, the fan 32, the atomizing nozzle 33, the water storage mesh 34 and the like, realizes that the water mist accumulated in the atomizing cover 31 is continuously and stably fed into the humidity control cavity 1 by utilizing the fan 32, and can accurately and efficiently regulate the humidifying degree of the humidity control cavity 1 by combining all valve members.
