[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example: Reference Figure 1 , Figure 2 and Figure 3 A waterproof weighing sensor shown includes a shell 1, a fixing seat 2 is fixed in the middle of the inner bottom surface of the shell 1, an elastic element 3 is fixed in the middle of the upper end surface of the fixing seat 2, and a data line module 301 is installed on the side of the shell 1, and the data line module 301 is electrically connected to the elastic element 3, so that when weighing is performed through the elastic element 3, the weighing data can be output through the data line module 301.
[0026] In addition, a load body 4 is fixed to the top of the elastic element 3, and a vertical load column 401 is fixed to the upper end surface of the load body 4. The top of the load column 401 extends out of the top of the shell 1 and is fixed with a load cap 5. The load cap 5 is a truncated cone structure and can bear weight through the load cap 5, so that the load body 4 and the elastic element 3 can be used for weighing.
[0027] Among them, a first waterproof membrane 6 is fixed inside the top of the housing 1, and the first waterproof membrane 6 is arranged around the top of the load column 401, and the edge of the first waterproof membrane 6 is tilted downward, and a drainage hole 601 is opened on the top side of the housing 1 to match the edge of the first waterproof membrane 6, and in this embodiment, the bottom diameter of the load cap 5 is larger than the top diameter of the load column 401. Therefore, the load cap 5 can prevent water from entering the housing 1 through the edge of the load column 401, and after being covered and protected by the load cap 5, the water will also be guided to the drainage hole 601 under the action of the tilted first waterproof membrane 6 to achieve the effect of primary waterproofing.
[0028] At the same time, a second waterproof membrane 7 is fixed to the inner middle part of the outer shell 1. The second waterproof membrane 7 is arranged around the bottom of the load body 4, and the edge of the second waterproof membrane 7 is inclined downward. A vertical water pipe 701 is fixed to the edge of the second waterproof membrane 7. The lower end of the water pipe 701 extends into the drying chamber 8 correspondingly opened at the bottom of the outer shell 1. Therefore, water that accidentally penetrates into the outer shell 1 can be further guided through the second waterproof membrane 7 and discharged into the drying chamber 8 through the water pipe 701, forming secondary waterproofing.
[0029] like Figure 2 and Figure 4 As shown, the bottom of the drying chamber 8 is provided with an opening, and is located in the middle of the bottom surface of the shell 1, and a collection box 9 is detachably installed at the bottom of the drying chamber 8 by means of threads, and a plurality of desiccants 10 are placed in the collection box 9. In the present embodiment, the desiccant 10 is an activated carbon bag.
[0030] In a specific implementation, a groove 901 is opened in the middle of the lower end surface of the collection box 9 , and a screw ear 902 is fixed in the groove 901 , so as to facilitate the collection box 9 to be rotated and taken out from the bottom of the shell 1 .
[0031] The waterproof weighing sensor can use the load cap 5 to cover the top edge of the load column 401, and then cooperate with the first waterproof membrane 6 to allow water to flow along the first waterproof membrane 6 to the edge and be discharged in cooperation with the drainage hole 601. At the same time, by using the setting of the second waterproof membrane 7, the water that accidentally penetrates into the housing 1 can be further guided to be discharged into the drying chamber 8 through the water guide pipe 701 to form secondary waterproofing, and is collected and processed by the collection box 9 in the drying chamber 8, thereby greatly improving the waterproof effect and having a good use effect.
