Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A type of time relay, such as Figures 1-5 As shown, the device includes a housing 1. One end of the housing 1 is fitted with a mounting base 2, and the other end is fitted with a cover 3. The mounting base 2 facilitates the installation of a time relay. A connecting plate 7 is fixedly connected to the upper end of the mounting base 2. A protective component is riveted to one side of the connecting plate 7 and covers the housing 1. The protective component includes a flow guiding component and a drying component. The flow guiding component is riveted to the connecting plate 7 and is located above the housing 1. Two sets of drying components are provided. The two sets of drying components are fixed to both sides of the flow guiding component by bolts, and the two sets of drying components cooperate with both sides of the flow guiding component. The two sets of drying components are located on both sides of the housing 1.

[0026] The protective component is installed by riveting it to the upper end of the mounting base 2 via the connecting plate 7. The protective component consists of two parts: a flow guiding component and a drying component. When encountering humid weather, the air humidity is high, and the surface of the time relay is damp, which may even form water droplets. The moisture in the air is guided into the drying component by the flow guiding component. The drying component absorbs the moisture, preventing damage caused by excessive moisture on the surface of the time relay. The reduced moisture on the surface of the time relay also makes the outer shell less prone to corrosion.

[0027] like Figures 1-5As shown, the adapter plate 7 is provided with a rectangular opening 8, the flow guide assembly includes a U-shaped frame 9, one end of the U-shaped frame 9 is riveted to the rectangular opening 8, a top through hole 10 is provided in the middle of the upper end of the U-shaped frame 9, a flow guide plate 11 is fixedly connected inside the top through hole 10, flow guide holes 12 are provided on both sides of the U-shaped frame 9, and both ends of the flow guide plate 11 respectively penetrate two groups of flow guide holes 12, and both ends of the flow guide plate 11 are located in two groups of drying assemblies.

[0028] One end of the U-shaped frame 9 is fixedly connected with a rectangular block, the rectangular block is riveted with the rectangular opening 8, and the U-shaped frame 9 is inverted and covers the upper end of the time relay. The upper end of the time relay is covered, and the water condensation in the air forms water droplets and flows to the flow guide plate 11 through the top through hole 10, or the humid air contacts the bottom of the flow guide plate 11 and condenses and slides along the flow guide plate 11 into the inside of the drying assembly.

[0029] As shown in Figures 1-5 The drying assembly includes a side frame 13, the side frame 13 is bolted to the side of the U-shaped frame 9, the sponge 14 is clamped on the inside upper end of the side frame 13, the material groove 15 is inserted into the inside lower end of the side frame 13, and both ends of the flow guide plate 11 are respectively inserted into two groups of sponges 14.

[0030] The flow guide plate 11 is inclined, the flow guide plate 11 guides water to the side frame 13, preventing water droplets from falling on the shell 1, the water droplets enter the inside of the side frame 13 through the flow guide plate 11 and the flow guide hole 12, and are absorbed by the sponge 14. The inside of the material groove 15 is filled with a drying agent, the water is absorbed and dried by the drying agent, and the moisture around the time relay is effectively absorbed.

[0031] As shown in Figures 3-5 Both sides of the two groups of side frames 13 are rotatably connected with upper and lower sealing plates 17 and 18, the upper and lower sealing plates 17 and 18 are located on one side of the sponge 14 and the material groove 15 respectively, a plurality of clamping grooves 16 are provided on one end of the U-shaped frame 9, the upper and lower sealing plates 17 and 18 are fixedly connected with elastic plates 20 on one side, and a plurality of elastic plates 20 are respectively clamped and installed with a plurality of clamping grooves 16.

[0032] The upper and lower sealing plates 17 and 18 are sealed on one side of the side frame 13, the corresponding upper and lower sealing plates 17 and 18 are opened, the material groove 15 can be pulled out, the sponge 14 or the drying agent can be replaced, and the upper and lower sealing plates 17 and 18 are clamped and installed through the elastic plates 20 and the clamping grooves 16, preventing the upper and lower sealing plates 17 and 18 from shaking.

[0033] As shown in Figure 4 A plurality of clamping grooves 4 are provided on the side wall of the shell 1, clamping plates 5 are fixedly connected on the cover 3 and the mounting seat 2, and a plurality of clamping plates 5 are respectively clamped and installed with a plurality of buckles.

[0034] The cover 3 and the mounting seat 2 are installed on the shell 1 through the clamping plates 5 and the clamping grooves 4, so that the three are clamped and installed as a whole.

[0035] As Figure 2 , Figure 4 , Figure 5 The back of the mounting seat 2 is slidably connected with a locking seat 6, and the side walls of the two groups of side frames 13 are each provided with a hole 19.

[0036] When the mounting seat 2 is installed, the sliding locking seat 6 can make the mounting seat 2 stable, and the hole 19 is convenient for the desiccant to absorb the humid air around the time relay.

[0037] The working principle of the time relay is as follows:

[0038] The protective assembly is riveted and installed on the upper end of the mounting seat 2 through the connecting plate 7, and the protective assembly includes a flow guide assembly and a drying assembly. When the air humidity is large due to the weather in the south, the surface humidity of the time relay is large, and even water droplets may be formed. The moisture in the air is guided into the inside of the side frame 13 by the flow guide plate 11, and the moisture is absorbed by the sponge 14 and the desiccant. The surface humidity of the time relay is large, which can avoid damage, and the surface humidity of the time relay is reduced, and the shell is not easy to be corroded.

[0039] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the utility model.
