[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0018] Please refer to Figures 1 to 5 The utility model provides a kind of technical scheme: a waterproof pressure controller, including pressure sensor main part 1, waterproof glue is injected in the inside of pressure sensor main part 1, the structure in the inside of pressure sensor main part 1 is prior art and will not be described in detail, pressure pipe 2 installed in the top of pressure sensor main part 1, and terminal 3 symmetrically arranged in the bottom of pressure sensor main part 1, the outside of pressure sensor main part 1 is equipped with waterproof layer 4, waterproof layer 4 can be sealed between pressure sensor main part 1 and pressure pipe 2 and terminal 3 from outside, improve waterproof effect, can be more effectively respond to harsh environment, greatly reduce the probability of water leakage, and waterproof layer 4 extends to the outside of pressure pipe 2 and terminal 3 respectively, the outside of pressure pipe 2 is equipped with multiple convex rings 6, convex ring 6 can increase the contact area between waterproof layer 4, to improve the sealing effect of waterproof layer 4, the outside of two terminals 3 is sequentially equipped with first sealing sleeve 5 and second sealing sleeve 7 from top to bottom, first sealing sleeve 5 is used to seal between pressure sensor main part 1 and terminal 3, second sealing sleeve 7 can be sealed between terminal 3 and waterproof layer 4, to further improve the sealing effect of waterproof layer 4.

[0019] The outer side of the terminal 3 is provided with a groove 8, the inner side of the first sealing sleeve 5 and the second sealing sleeve 7 are provided with a convex edge 9 matched with the groove 8, and the convex edge 9 and the groove 8 are matched to fix the first sealing sleeve 5 or the second sealing sleeve 7 and prevent movement.

[0020] The waterproof layer 4 is made of hot melt adhesive, the hot melt adhesive can be rapidly melted and penetrated into the gap between the pressure sensor main body 1 and the pressure pipe 2 and the first sealing sleeve 5 after being heated, and the hot melt adhesive can be rapidly solidified to form firm adhesion after cooling, thereby achieving the sealing effect, and the hot melt adhesive has good chemical stability, thereby ensuring the durability and reliability of the sealing, and the hot melt adhesive is non-toxic and odorless and cannot cause environmental pollution.

[0021] The first sealing sleeve 5 and the second sealing sleeve 7 are made of rubber, and the rubber has good elasticity and can achieve excellent sealing effect.
