When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] Example 1

[0048] This embodiment proposes a moisture-proof meter box, such as... Figures 1-10 As shown, the moisture-proof meter box includes a box body 1, a box door (not shown in the figure), and a control module (not shown in the figure). The box door is rotatably connected to the box body 1, as shown in the figure. Figure 1 and Figure 3 As shown, an electric meter 3 and a dehumidification device are installed inside the housing 1. The dehumidification device includes a moisture-absorbing part 5, a heat-absorbing part 6, and a wind-absorbing part 2. The moisture-absorbing part 5, the heat-absorbing part 6, and the wind-absorbing part 2 are all used to dehumidify the inside of the housing 1.

[0049] The moisture-proof meter box described in this embodiment uses multiple dehumidification methods: the moisture-absorbing part 5 absorbs and removes moisture from the box 1; the heat-absorbing part 6 heats and removes moisture from the box 1; and the air-absorbing part 2 blows and removes moisture from the box 1. The moisture-absorbing part 5, the heat-absorbing part 6, and the air-absorbing part 2 are interconnected and work together to achieve good dehumidification, improve the dryness inside the box 1, and extend the service life of the wires inside the box 1.

[0050] Specifically, such as Figure 1 As shown, the housing 1 includes an upper panel 11, a lower panel 12, a left panel 13, a right panel 14, and a rear panel 15.

[0051] Specifically, such as Figure 4 As shown, the moisture-absorbing part 5 includes a superabsorbent polymer 54 and a first housing 51, wherein the superabsorbent polymer 54 is uniformly and fixedly disposed inside the first housing 51.

[0052] Superabsorbent polymer 54 has an extremely strong water absorption effect and can absorb moisture inside the box 1. The weight of superabsorbent polymer 54 will increase after absorbing water.

[0053] More specifically, the amount of the high polymer water-absorbing resin 54 is not limited.

[0054] More specifically, as shown in Figure 5 An air inlet hole 511 and an air outlet hole 512 are arranged on the first shell 51.

[0055] More specifically, as shown in Figure 4 and Figure 5 The first shell 51 is of a hollow structure, and a baffle assembly 52 is arranged in the first shell 51. The baffle assembly 52 comprises a second baffle 521 and a third baffle 522, and divides the first shell 51 into four first cavities 53. The high polymer water-absorbing resin 54 is arranged in the first cavities 53.

[0056] More specifically, as shown in Figure 5 An air flow hole 523 is arranged on the baffle assembly 52. This arrangement facilitates the air flow in the first cavities 53.

[0057] Specifically, the heat-drying part 6 comprises a self-heating bag 63 and a second shell 61. The self-heating bag 63 is fixed in the second shell 61.

[0058] This arrangement can, on one hand, remove the moisture in the box 1 by heating the moisture after the self-heating bag 63 is activated, and improve the dehumidification effect. On the other hand, the heat source for heating and warming of the heat-drying part 6 is provided by the heat release of the supersaturated solution in the self-heating bag 63, and no additional heating component is needed, thereby reducing the power consumption.

[0059] Specifically, the self-heating bag 63 contains a supersaturated solution, as shown in Figure 6 A button device 64 is arranged on the self-heating bag 63, and the button device 64 is in contact with the supersaturated solution.

[0060] When activated, the button device 64 is gently pressed, and the supersaturated solution in the self-heating bag 63 generates a heat release reaction under the driving of the button device 64, and no additional heating component is needed, thereby reducing the power consumption.

[0061] In addition, when the temperature inside the box 1 is high, the supersaturated solution in the self-heating bag 63 will absorb heat and change from solid to liquid, which is conducive to the heat dissipation of the box 1. The self-heating bag 63 can be reused, thereby saving resources.

[0062] Specifically, the supersaturated solution is not limited. In the embodiment, the supersaturated solution can be a supersaturated sodium acid solution. The supersaturated sodium acid solution is harmless to the human body.

[0063] More specifically, as shown in Figure 7As shown, the second shell 61 is hollow inside, and the hollow structure of the second shell 61 forms a second cavity 62. A self-heating bag 63 is installed inside the second cavity 62.

[0064] More specifically, as shown in the drawings, Figure 6 As shown, a partition 65 is arranged on the self-heating bag 63, which divides the self-heating bag 63 into four independent supersaturated solution holding cavities.

[0065] More specifically, as shown in the drawings, Figure 7 As shown, a mounting hole 66 is arranged on the second shell 61, and as shown, Figure 2 The button device 64 is mounted in the mounting hole 66, and the button device 64 is arranged outside the moisture absorption part 5 through the mounting hole 66.

[0066] This arrangement is convenient for mounting the button device 64 and exposing the button device 64, thereby facilitating the start of the exothermic reaction of the supersaturated solution in the self-heating bag 63.

[0067] More specifically, as shown in the drawings, Figure 1 , Figure 2 and Figure 3 The hot drying part 6 is arranged directly above the moisture absorption part 5.

[0068] This arrangement removes the moisture in the box 1 by heating the hot drying part 6, and also removes the moisture absorbed by the high-molecular water-absorbing resin 54 in the moisture absorption part 5 by heating, thereby increasing the water absorption capacity and service life of the high-molecular water-absorbing resin 54 in the moisture absorption part 5.

[0069] More specifically, the air drying part 2 includes a first fan 21 and a second fan 22, which are symmetrically arranged inside the box 1.

[0070] This arrangement facilitates the air drying part 2 to remove the moisture in the box 1 by blowing, thereby improving the dehumidification effect, and is also conducive to heat dissipation and dust removal in the box 1.

[0071] More specifically, a telescopic assembly 7 is arranged inside the box 1, which is used to press and start the hot drying part 6 to dehumidify the inside of the box 1.

[0072] The telescopic assembly 7 is associated with the hot drying part 6 and cannot be separated, and the telescopic assembly 7 can be pressed to start the hot drying part 6 to dehumidify the inside of the box 1, thereby improving the dehumidification effect.

[0073] More specifically, a telescopic adjustment device 4 is arranged on the box 1, which is used to adjust the extension or retraction of the telescopic assembly 7.

[0074] The telescopic adjustment device 4, the telescopic component 7, and the heating element 6 are interconnected and inseparable. The telescopic adjustment device 4 can control the telescopic component 7 to extend and activate the heating element 6 to dehumidify the interior of the box 1, thereby improving the dehumidification effect.

[0075] The air inlet 511 is located on the left rear of the first housing 51. This arrangement ensures that when air enters the interior of the first housing 51, it will first enter the interior of the first cavity 53 located on the left rear. As a result, the superabsorbent polymer 54 in the first cavity 53 located on the left rear absorbs moisture first. Therefore, the weight of the superabsorbent polymer 54 in the first cavity 53 located on the left rear increases first, which causes an imbalance in the moisture absorption section 5.

[0076] The moisture-absorbing part 5, the telescopic adjustment device 4, the telescopic component 7, and the heated part 6 are interconnected and work together. When the moisture-absorbing part 5 begins to absorb moisture from the box 1, the moisture-absorbing part 5 will become unbalanced. When the telescopic adjustment device 4 detects the unbalance of the moisture-absorbing part 5, it adjusts the current that triggers the telescopic component 7 to extend and retract, thereby adjusting the extension of the telescopic component 7. When the telescopic component 7 extends, it presses the button device 64 to activate the heated part 6 to dehumidify the interior of the box 1.

[0077] The moisture-absorbing section 5, the telescopic adjustment device 4, the telescopic component 7, and the heated section 6 are interconnected and inseparable, playing multiple roles. First, the moisture-absorbing section 5 and the heated section 6 work together to remove moisture from the cabinet 1, improving the dehumidification effect. Second, the heat source for the heated section 6 is provided by the exothermic reaction of the supersaturated solution in the self-heating bag 63, eliminating the need for an additional heating component and reducing energy consumption. Third, the heated section 6 is activated simultaneously with the moisture-absorbing section 5 absorbing moisture from the cabinet 1, which increases the water absorption capacity and service life of the superabsorbent polymer 54 in the moisture-absorbing section 5. Fourth, when the internal temperature of the cabinet 1 is high, the supersaturated solution in the self-heating bag 63 absorbs heat and changes from solid to liquid, which is beneficial for the heat dissipation of the cabinet 1.

[0078] Specifically, such as Figure 1 As shown, a first partition 16 is provided inside the housing 1, which divides the interior of the housing 1 into a first installation area 101 and a second installation area 102. An electric meter 3 is installed in the first installation area 101, and a moisture-absorbing part 5 and a heat-absorbing part 6 are installed in the second installation area 102. An air-absorbing part 2 is installed on the first partition 16.

[0079] More specifically, such as Figure 1 The first vent 161 and the second vent 162 are symmetrically arranged on the first partition 16. A first fan 21 is installed in the first vent 161 and a second fan 22 is installed in the second vent 162.

[0080] Specifically, the moisture absorption part 5 is installed at the center of the upper surface of the lower panel 12 of the box 1, the telescopic adjusting device 4 is installed at the center of the lower surface of the lower panel 12, the telescopic components 7 are evenly installed around the moisture absorption part 5, and the telescopic components 7 are installed right below the button device 64.

[0081] This arrangement is ingenious. On the one hand, the telescopic adjusting device 4 can monitor the balance of the moisture absorption part 5 to control the extension of the telescopic components 7. On the other hand, the telescopic components 7 can press the button device 64 to start the heat drying part 6 to dehumidify the inside of the box 1 after being extended.

[0082] Specifically, the number of the telescopic components 7 is not limited.

[0083] In this embodiment, as shown in Figure 1 and Figure 2 , the number of the telescopic components 7 is set to four.

[0084] As shown in Figure 8 , the telescopic components 7 are arranged in multiple sections, and the circuits triggering the extension and contraction of the sections are connected in parallel.

[0085] More specifically, as shown in Figure 9 and Figure 10 , the telescopic adjusting device 4 includes a center ball 41 at the center of the lower panel 12, a flat surface 42 supporting the center ball 41, and a sliding resistor 43 arranged along the line connecting the center ball 41 and the telescopic components 7. The sliding resistor 43 includes a sliding part 431 and a stationary part 432. The sliding part 431 is sleeved on the outside of the stationary part 432, and the outer end of the sliding part 431 is connected to the center ball 41. The number of the sliding resistors 43 is the same as the number of the telescopic components 7, and the sliding resistors 43 are connected in series with the circuits triggering the extension and contraction of the telescopic components 7. The arrangement of the telescopic adjusting device 4 can quickly and accurately control the current of the telescopic components 7.

[0086] When the moisture absorption part 5 starts to absorb the moisture in the box 1, the moisture absorption part 5 will be unbalanced. When the telescopic adjusting device 4 detects that the moisture absorption part 5 is unbalanced, the telescopic adjusting device 4 controls the center ball 41 to tilt and slide to one side, pushing the sliding part 431 of the sliding resistor 43 on the tilted side to slide to the side of the stationary part 432, making the resistance smaller; the sliding part 431 of the sliding resistor 43 on the other side slides to the outside of the stationary part 432, making the resistance larger; thereby the current of the corresponding telescopic components 7 becomes larger and smaller, prompting the telescopic components 7 on the tilted side to extend and the telescopic components 7 on the other side to shorten.

[0087] In the embodiment, the number of the telescopic components 7 and the number of the slide resistors 43 are both set to four.

[0088] Specifically, a weight sensor (not shown in the figure) is arranged below the polymer water-absorbing resin 54, the weight sensor is used to detect the weight of the polymer water-absorbing resin 54, and the weight sensor is in communication connection with the control module.

[0089] The weight of the polymer water-absorbing resin 54 increases after absorbing water, and the more water the polymer water-absorbing resin 54 absorbs, the more the weight increases. The water absorption capacity of the polymer water-absorbing resin 54 is constant, and when the water absorption capacity of the polymer water-absorbing resin 54 reaches the maximum, the weight of the polymer water-absorbing resin 54 also reaches the maximum, and the polymer water-absorbing resin 54 no longer absorbs water, and the weight of the polymer water-absorbing resin 54 no longer increases.

[0090] For the moisture-proof electric meter box, in addition to the box body 1, the box door, the control module, the electric meter 3, the moisture-absorbing part 5, the heat-drying part 6, the telescopic adjusting device 4 of the air-drying part 2 and the telescopic component 7, it also includes other related components. Since the specific structure and the specific assembly relationship of the related components are prior art, they will not be described here.

[0091] The moisture-absorbing part 5, the telescopic adjusting device 4, the telescopic component 7, the heat-drying part 6, the weight sensor of the air-drying part 2 and the control module are interrelated and inseparable, novel in concept and ingenious in design, and play multiple roles. First, the dehumidification method is various. The moisture-absorbing part 5 is used to absorb and remove the moisture in the box body 1; the heat-drying part 6 is used to heat and remove the moisture in the box body 1; the air-drying part 2 is used to blow and remove the moisture in the box body 1, which improves the dehumidification effect; second, the heat source of the heat-drying part 6 is provided by the heat release of the supersaturated solution in the self-heating bag 63, which does not need additional heating components, reducing power consumption; third, when the moisture-absorbing part 5 starts to absorb the moisture in the box body 1, the telescopic adjusting device 4 detects the imbalance of the moisture-absorbing part 5, and controls the telescopic component 7 to start the heat-drying part 6, which can increase the water absorption capacity and service life of the polymer water-absorbing resin 54 in the moisture-absorbing part 5; fourth, when the internal temperature of the box body 1 is high, the supersaturated solution in the self-heating bag 63 will absorb heat and change from solid to liquid, which is beneficial to the heat dissipation of the box body 1.

[0092] Compared with the prior art, the moisture-proof electric meter box of the embodiment has various dehumidification methods. The moisture-absorbing part 5 is used to absorb and remove the moisture in the box body 1; the heat-drying part 6 is used to heat and remove the moisture in the box body 1; the air-drying part 2 is used to blow and remove the moisture in the box body 1; the moisture-absorbing part 5, the heat-drying part 6 and the air-drying part 2 are interrelated and jointly act, which has good dehumidification effect, improves the dryness of the box body 1 and prolongs the service life of the electric wire in the box body.
