Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, integrally connected, or detachably connected; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the above terms in the present invention in specific situations.

Example 1:

as shown in fig. 1, 2 and 3, a submersible electric film rolling machine comprises an electric film rolling machine body and an exhaust mechanism, wherein the electric film rolling machine body comprises a shell 1, the exhaust mechanism comprises an exhaust channel 2, the inlet of the exhaust channel 2 is communicated with the inside of the shell 1, the outlet of the exhaust channel 2 is arranged outside the shell 1, the exhaust channel 2 is in a sealed state when the gas pressure inside the shell 1 is less than a threshold value, and the outlet of the exhaust channel 2 is opened when the gas pressure inside the shell 1 is greater than the threshold value.

When the inside atmospheric pressure of casing 1 is less than the threshold value, exhaust passage 2 export is in the closed condition, and inside water can't get into casing 1, when the inside atmospheric pressure of casing 1 is greater than the threshold value, exhaust passage 2's export is opened, and gas outgoing, when discharging to atmospheric pressure be less than the threshold value after, exhaust passage 2 in time closes, prevents that water from getting into inside casing 1.

Further, the outlet end of the exhaust channel 2 comprises a meshing top 201 and a meshing bottom 202, the meshing top 201 and the meshing bottom 202 are kept in a closed state when the internal gas pressure of the electric film rolling device body is smaller than a threshold value, the meshing top 201 and the meshing bottom 202 are in contact connection, the outlet of the exhaust channel 2 is closed, and the outlet of the exhaust channel 2 is opened when the internal gas pressure of the electric film rolling device body is larger than the threshold value; the exhaust passage 2 is made of flexible material with elasticity.

The utility model discloses in, exhaust passage 2 can use and have elastic rubber material to make, processing during exhaust passage 2, can with exhaust passage 2 processes for duckbilled, makes interlock top 201, interlock bottom 202 keep laminating under the effect of material self elasticity, so as to realize making interlock top 201, interlock bottom 202 keep the purpose of closed state when electronic film rolling device body inside gas pressure is less than the threshold value.

Further, the exhaust passage 2 has a structure in which an inlet is larger than an outlet. With this structure, the gas storage amount at the inlet of the exhaust passage 2 is larger than that at the outlet, increasing the flow rate of the gas reaching the outlet of the exhaust passage 2, preventing water from rushing into the interior of the housing 1 during the exhaust process.

Further, the exhaust hood 3 is of a concave structure, the exhaust hood 3 is connected with the shell 1, and the outlet of the exhaust channel 2 is arranged in the concave part of the exhaust hood 3. When water flows to the outlet of the exhaust passage 2 from a direction parallel to the outlet of the exhaust passage 2, the water flow is prevented from rushing between the meshing top 201 and the meshing bottom 202 due to the shielding effect of the exhaust hood 3, and the waterproof effect of the exhaust passage 2 is disabled.

Furthermore, a plurality of concave holes 4 are formed in the shell 1, and the clamping columns 301 are correspondingly arranged on the shell 1; the clamping column 301 is in interference fit with the concave hole 4. Through inciting somebody to action card post 301 card is gone into in the shrinkage pool 4, can realize right the fixed of air discharge hood 3 is worked as when the damaged needs of taking place of air discharge hood 3 are changed, will card post 301 is followed break away from in the shrinkage pool 4 and can realize right the demolising of air discharge hood 3.

Further, the exhaust passage 2 is integrally formed. The integral molding enables the exhaust passage 2 to have good sealing performance except for the inlet and the outlet when the exhaust passage is in a closed state, and prevents gas from entering the shell 1.

Example 2:

as shown in fig. 4, different from the embodiment, the exhaust mechanism further includes an elastic ring 203, the elastic ring 203 is sleeved outside the sidewall at the outlet of the exhaust channel 2, and in the initial state, the exhaust channel 2 is in the closed state under the action of the elastic ring 203.

The elastic ring 203 is tightly hooped at the outlet of the exhaust channel 2, so that the outlet of the exhaust channel 2 has good sealing performance.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the details of the embodiments in the above description, and the technical concept of the present invention can be within the scope of the present invention, and can be modified to various simple modifications, and these simple modifications all belong to the protection scope of the present invention. It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and in order to avoid unnecessary repetition, the present invention does not need to describe any combination of the features.
