[0065] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0066] In the description of the utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0067] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0068] Combine the following Figures 1 to 13 , describing an embodiment of the utility model.

[0069] According to an embodiment of the present utility model, on the one hand, as Figure 1-Figure 3 As shown, a dehumidification box is provided, comprising:

[0070] A shell 1, wherein a desiccant is disposed in the inner cavity of the shell 1;

[0071] An evaporation component 2 is arranged in the inner cavity and is used to evaporate the moisture absorbed by the desiccant;

[0072] The condensation component 3 includes a condensation sheet 31. At least a portion of the condensation sheet 31 is covered on the periphery of the evaporation component 2 and is suitable for collecting water vapor generated by evaporation of water and converting it into condensed water.

[0073] The dehumidifier box provided by the utility model collects the water vapor generated by the evaporation component 2 by arranging a condensation component 3, and condenses the water vapor into condensed water, which is convenient for collection and treatment. Therefore, the water evaporated from the desiccant will not escape into the environment where the dehumidifier box is located. During the use of the dehumidifier box, the two processes of absorbing moisture and evaporating moisture do not need to be completed in different spaces, which greatly improves the operating convenience of the dehumidifier box, is easy to use, and effectively improves customer satisfaction.

[0074] It should be noted that the shape of the shell 1 is not unique, and can be a quadrangular prism, a polygonal prism, or a cylinder, etc., without specific limitation. The shell 1 is provided with a plurality of holes for air circulation (not shown in the figure), and the holes connect the external environment with the inner cavity of the shell 1. The humid air can enter the inner cavity of the shell 1 through the holes and be absorbed by the desiccant. The power for the humid air to enter the shell 1 can be the humidity difference, and of course a fan can also be provided for forced convection ventilation.

[0075] In a specific implementation, a switch structure can be provided on the multiple pores on the housing 1, and the switch structure can control the pores to selectively enter an open state or a closed state. When the dehumidification box turns on the dehumidification function, the switch structure opens the pores, so that the inner cavity of the dehumidification box is connected to the external environment to absorb moisture in the environment. When the ambient humidity is good and the dehumidification function does not need to be turned on, the pores can be controlled to enter a closed state; or, when the evaporation component needs to be started after the desiccant is saturated, the pores are started to enter a closed state, and the desiccant is dried in a relatively closed environment.

[0076] In some embodiments, the condensing assembly 3 further includes a cooling device 32 , which is connected to the condensing plate 31 and is suitable for providing cooling to the condensing plate 31 .

[0077] A device connected to the condensing sheet 31 is provided to provide cooling capacity for the condensing sheet 31, so that the condensing sheet 31 can be cooled down quickly. When the water vapor generated after the evaporation of the water in the desiccant diffuses around, it can quickly condense into condensed water after encountering the condensing sheet 31, and flow down along the wall of the condensing sheet 31 under the action of gravity. Such a configuration improves the condensation efficiency of the water vapor and achieves the purpose of fully and effectively collecting the water vapor formed after evaporation.

[0078] In some embodiments, the cooling device 32 includes a heat exchanger 321 , and the heat exchanger 321 has a heat exchange cold end, and the heat exchange cold end is connected to the condensing plate 31 .

[0079] The heat exchanger 321 is used to supply cooling to the condensing plate 31 , which has a simple structure and high cooling efficiency. It can continuously and stably supply cooling to the condensing plate 31 , and the dehumidification box can operate reliably for a long time.

[0080] In some embodiments, the heat exchanger may be an evaporator, which exchanges heat between the low-temperature condensed liquid and the outside air, and absorbs heat through vaporization to achieve a refrigeration effect. The evaporator is usually composed of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for liquid evaporation to promote the boiling and vaporization of the liquid, while the evaporation chamber completely separates the gas and liquid phases.

[0081] In some other embodiments, a compression refrigerator or a lithium bromide absorption refrigeration method may be used, as long as the purpose of providing cooling capacity can be achieved. A compression refrigerator can produce low-temperature cold water, which can continuously take away the heat of the condensing sheet 31 connected to it for heat exchange.

[0082] In some embodiments, the condensation assembly 3 further includes a condensation water collection structure 33 , which is disposed below the condensation sheet 31 , so that the condensation water collected by the condensation sheet 31 enters the condensation water collection structure 33 under the action of gravity.

[0083] A condensate collecting structure 33 specifically used for collecting condensate is provided below the condensate sheet 31. Condensate is collected by the property that the condensate flows downward due to its own gravity, without the need to provide other components such as pipelines. The structure is simple and the collection is convenient.

[0084] In some embodiments, the condensate collection structure 33 includes a water collecting tank 331, which is arranged below the shell 1; a leakage hole 111 is provided at the connection between the shell 1 and the water collecting tank 331, which is used to connect the inner cavity of the shell 1 with the accommodating cavity of the water collecting tank 331.

[0085] The water collecting box 331 is arranged below the shell 1 , and the condensed water collected by the condensing sheet 31 flows down along the condensing sheet 31 , and flows from the water leakage hole 111 into the accommodating cavity of the water collecting box 331 for temporary storage.

[0086] Specifically, Figure 2 and Figure 3 As shown, the condensing sheet 31 can be set as a cover with an open bottom, and the semi-enclosed cover is set above the heat conducting plate 22 and the desiccant. After the desiccant is heated, the water adsorbed in the desiccant evaporates due to the heat, and diffuses upward and around. During the diffusion process, it encounters the condensing sheet 31 in the diffusion path. The steam condenses on the surface of the condensing sheet 31 when it is cold, and flows downward along the condensing sheet 31 under the action of gravity, and flows into the water collecting tank 331 through the water leakage hole 111, completing the collection of water vapor, avoiding the water vapor returning to the dehumidification environment to cause poor dehumidification effect, or even unable to truly dehumidify, resulting in a counterproductive situation. The water leakage hole 111 can adopt a microporous structure to guide the condensed water collected on the bottom surface of the shell 1 into the water collecting tank 331. It is also possible to adopt a method in which the periphery of the water leakage hole 111 is lower than other parts of the shell 1, so as to facilitate the drainage of condensed water and guide it to the water collecting tank 331 through the water leakage hole 111.

[0087] In some embodiments, the evaporation assembly 2 includes:

[0088] like Figure 5 The heating element 21 shown is used to provide evaporation heat;

[0089] like Figure 4 The heat conducting plate 22 is shown, and the heating element 21 is disposed on the heat conducting plate 22 . The heat conducting plate 22 is located close to the desiccant, and the heating element 21 transfers heat to the desiccant through the heat conducting plate 22 .

[0090] The heat generated by the heating element 21 is effectively transferred to the desiccant by the heat conducting plate 22, thereby increasing the heat conducting area, so that the desiccant can be fully heated and the water evaporates evenly.

[0091] In some embodiments, the evaporation component 2 further includes Figure 6 As shown in the pressing sheet 23 , the heating element 21 is pressed tightly onto the heat conducting plate 22 by the pressing sheet 23 .

[0092] like Figure 7 As shown, the heating element 21 is pressed more tightly onto the heat conducting plate 22 by the pressing sheet 23, so that the heat generated by the heating element 21 can be more fully transferred to the heat conducting plate 22, thereby effectively heating the desiccant to absorb water for evaporation, thereby improving the evaporation efficiency.

[0093] In some embodiments, a shelf (not shown) is disposed in the housing 1 , and the shelf divides the inner cavity into an evaporation cavity and a condensed water delivery cavity, and the desiccant and the evaporation component 2 are both disposed in the evaporation cavity.

[0094] The inner cavity of the shell 1 is divided into an evaporation cavity and a condensed water delivery cavity by a shelf. The desiccant and the evaporation component 2 are both arranged in the evaporation cavity and isolated from the condensed water delivery cavity to prevent the desiccant from contacting with the condensed water and affecting the drying of the desiccant.

[0095] Specifically, the shelf is arranged between the bottom surface of the housing 1 and the heat conducting plate 22, and the desiccant is placed on the upper side of the shelf to fully absorb the heat transferred by the heat conducting plate 22. A weight sensor for monitoring the weight of the desiccant can be arranged on the lower side of the shelf to accurately obtain the change in the weight of the desiccant.

[0096] like Figure 8 As shown, a control method of a dehumidification box of the utility model is shown, comprising the following steps:

[0097] S1, turn on the dehumidification function;

[0098] S2, obtaining the weight G1 of the desiccant, and comparing it with the first preset value G2;

[0099] S3, determine whether G1≥G2 is satisfied;

[0100] S4: If yes, start the evaporation component 2.

[0101] The first preset value G2 is the weight of the desiccant in a saturated state. G1≥G2 indicates that the desiccant is saturated. At this time, the evaporation component 2 needs to be started to evaporate the moisture absorbed by the desiccant. The above method can accurately grasp the saturation state of the desiccant, thereby timely controlling the opening of the evaporation component 2.

[0102] In some embodiments, Fig. 9 If not, the dehumidification function continues to run until G1≥G2.

[0103] If G1≥G2 is not satisfied, it indicates that the desiccant has not reached the saturation state. The desiccant can continue to absorb water vapor in the environment and perform dehumidification operations, so the dehumidification function can continue to operate.

[0104] In some embodiments, Fig.10 As shown, before turning on the dehumidification function, the environmental humidity detection step is also included:

[0105] Get the ambient humidity R1 and compare it with the preset humidity R2;

[0106] Determine whether R1≥R2 is satisfied;

[0107] If yes, turn on the dehumidification function.

[0108] First detect the ambient humidity, and then turn on the dehumidification function when the ambient humidity is high. When the preset humidity reaches R2, it indicates that the ambient humidity has reached the level that requires dehumidification. At this time, turn on the dehumidification function for automatic control.

[0109] It should be noted that if R1≥R2 is not satisfied, the dehumidification function will not be turned on.

[0110] When the detected ambient humidity does not reach the humidity value that requires dehumidification, there is no need to turn on the dehumidification function, saving energy.

[0111] In some embodiments, Fig.11 As shown, based on the previous embodiment, after starting the evaporation component 2, the following steps are also included:

[0112] Obtaining the weight G1 of the desiccant, and comparing it with the second preset value G0;

[0113] Determine whether G1=G0;

[0114] If yes, return to the ambient humidity detection step.

[0115] The second preset value G0 is the weight of the desiccant in an ideal dry state, or the weight of the desiccant when the moisture content is low and no further drying is required. When G1=G0 is satisfied, it indicates that the evaporation of the moisture in the desiccant has been completed, and the drying is stopped and the step of detecting the ambient humidity is returned. The saturation state of the desiccant is reflected by the weight change of the desiccant, which is more accurate and direct, and the control logic is simple. By accurately grasping and feeding back the saturation state of the desiccant, it is possible to accurately control whether the evaporation component 2 is turned on or off.

[0116] In some embodiments, Fig.12 As shown, based on the previous embodiment, the control method further includes a condensed water level detection step:

[0117] Get the condensed water level h1 and the preset water level h max Compare;

[0118] Determine whether h1≥h max ;

[0119] If so, issue a water pouring reminder.

[0120] Check the condensate water level to ensure that the water level reaches the highest warning water level h max A reminder is issued in time so that the user can dump the collected condensed water in time to prevent the condensed water from overflowing.

[0121] It should be noted that if Fig.13 As shown, after the dehumidification function is turned on, if R1<R2 is satisfied during the dehumidification process, it indicates that the ambient humidity has reached the requirement, and the dehumidification function can be directly turned off.

[0122] like Figure 3 As shown, the dehumidification box includes a shell 1 (drying box 11 + box cover 12), a PTC heater 21, a heat conducting plate 22, a pressing plate 23, a cooling device 32, a condensing plate 31 and a water collecting box 331. The inner cavity formed by the drying box 11 and the box cover 12 is equipped with an evaporation component 2 (PTC heater 21 + heat conducting plate 22 + pressing plate 23) for drying and desiccant particles for absorbing moisture in the environment. The PTC heater 21 is the heat source for drying. The heat conducting plate 22 can evenly transfer the heat generated by the PTC heater 21 to the desiccant particles inside the shell 1. The pressing plate 23 of the heater 21 can conduct the heat generated in the PTC heater 21 to the heat conducting plate 22 to a greater extent. The cooling device 32 provides coldness to the condensing plate 31 to condense and collect the water vapor generated during the heating and drying process. The condensing plate 31 is arranged on the periphery of the evaporation component 2 in the shell 1 to maximize the collection effect of the water vapor generated by evaporation. The water collecting tank 331 is installed below the condensing plate 31 to collect condensed water generated after condensation.

[0123] The device for detecting humidity of the desiccant can use a weight sensor, and the weight of the desiccant is measured by the weight sensor to detect the saturation state of the desiccant. Generally, common weight sensors such as resistive strain type weighing sensors, gyroscopic weighing sensors or capacitive weighing sensors can be selected, which are not limited here. When the detected humidity is low and the user uses it normally, press the power button. The device for detecting humidity of the desiccant can detect humidity. The water level detection sensor in the water collecting tank 331 can use a water level probe. The water level probe detects whether the water in the water collecting tank 331 is full, and the synchronous environmental humidity monitoring device detects whether the humidity of the humidity sensor meets the requirements. If the detected environmental humidity value R1 is less than the preset value R2, it indicates that the environmental humidity meets the requirements and there is no need to turn on the dehumidification function. If the humidity value in the detected environment is unqualified (R1≥R2), turn on the dehumidification function of the dehumidification box, and the desiccant absorbs moisture in the environment to achieve the dehumidification effect. The value range of R2 is generally 40% to 60%, which is selected and preset according to the application scenario of the dehumidification box. If the desiccant has absorbed water to a saturated state, the program will automatically control the PTC heating element 21 to perform a heating and drying operation to dehydrate and dry the desiccant. The dried water vapor can condense into condensed water droplets after encountering the condensation sheet 31, and finally be collected in the water collection tank 331. If the water level in the water collection tank 331 reaches a certain water level, the user will be reminded to pour water. A display area 13 is provided on the box cover 12, and the reminder to pour water will be highlighted in the display area 13, or a flashing reminder or an alarm sound can be used.

[0124] The dehumidifier box of the utility model is provided with a condensation component 3, which condenses the water vapor generated during the dehumidification process of the dehumidifier box and returns the condensed water to the water collecting tank 331, so as to prevent the water vapor generated during the dehumidification process from returning to the wardrobe, camera box and other drying environments. In addition, the sensor provided inside realizes intelligent control of dehumidification.

[0125] The dehumidification box with intelligent control of the utility model can realize the automatic drying and dehumidification of wardrobes, camera boxes and the like that users want to keep dry for a long time through relevant control logic and overall machine design layout.
