[ detailed description ] embodiments

The technical solutions of the embodiments of the present invention are explained and explained below with reference to the drawings of the embodiments of the present invention, but the embodiments described below are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

In the following description, the appearances of the indicating orientation or positional relationship, such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are only for convenience in describing the embodiments and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

Example (b):

as shown in fig. 1, the present embodiment shows a vacuum inhibitor, which includes a housing 1, an inner float 2 and an outer float 3.

The middle of the shell 1 is provided with a cavity, a partition plate 4 is arranged in the cavity, and the cavity is divided into an inner cavity 5 and an outer cavity 6 by the partition plate 4. The outer chamber 6 is closer to the liquid surface than the inner chamber 5. An outer through hole 7 is arranged at the bottom of the shell 1 (namely, the side wall of the outer cavity 6 close to the liquid level), the outer through hole 7 is communicated with the outer cavity 6, the outer floating ball 3 is movably arranged at the outer through hole 7, and meanwhile, the outer floating ball 3 is positioned outside the shell 1. When the liquid level is lower and the water amount in the tank body is insufficient, the outer floating ball 3 is separated from the liquid level, the air amount in the tank body is less, the air pressure in the tank body is insufficient, at the moment, the outer floating ball 3 is separated from the outer through hole 7 due to self weight, and the air in the outer cavity 6 flows into the tank body from the outer through hole 7 to be supplemented, so that the air pressure in the tank body is enhanced. If the liquid level is higher and contacts with the outer floating ball 3, the outer floating ball 3 moves towards the outer through hole 7 under the action of buoyancy and blocks the outer through hole 7, so that the outer through hole 7 is blocked from the air in the tank body.

The partition plate 4 is provided with an inner through hole 15, the inner cavity 5 and the outer cavity 6 are communicated through the inner through hole 15, air in the outer cavity 6 is supplemented from the inner cavity 5, the side wall of the inner cavity 5 is provided with a vent hole 16, and the inner cavity 5 is communicated with the atmosphere through the vent hole 16, so that the air in the inner cavity 5 is supplemented.

If the liquid level in the tank body is higher and the outer floating ball 3 can not stably seal the outer through hole 7, water in the tank body leaks into the outer cavity 6 at the outer through hole 7. In order to prevent the water in the outer cavity 6 from flowing into the inner cavity 5 from the inner through hole 15, the inner floating ball 2 is movably arranged at the inner through hole 15, and the inner floating ball 2 is arranged in the outer cavity 6. When the liquid level in the outer cavity 6 is not contacted with the inner floating ball 2, the inner floating ball 2 is separated from the inner through hole 15, and the air flowing from the vent hole 16 is supplemented into the outer cavity 6 through the inner through hole 15. When the liquid level in the outer cavity 6 is contacted with the inner floating ball 2, the inner floating ball 2 moves towards the inner through hole 15 under the action of buoyancy until the inner through hole 15 is blocked. At this time, water in the outer chamber 6 cannot enter the inner chamber 5.

The inner floating ball 2 and the outer floating ball 3 are matched to prevent water from entering the inner cavity 5 under most conditions, but the water has fluidity, so that the slight shaking of the inner floating ball 2 and the outer floating ball 3 can enable a large amount of water in the tank body to flow into the outer cavity 6 from the outer through hole 7, and the water in the outer cavity 6 flows into the inner cavity 5.

The outer 7 outsides of outer through-hole are provided with backup pad 8 in this embodiment, are provided with backup pad 9 No. two in the exocoel 6, and backup pad 8 and backup pad 9 parallel arrangement each other now, and outer through-hole 7 is located between backup pad 8 and the backup pad 9 No. two this moment. A backup pad 8 and No. two backup pads 9 are all fixed with casing 1 through fixed plate 17, and outer floater 3 is located between outer through-hole 7 and a backup pad 8, is provided with spring 10 between backup pad 8 and the outer floater 3, is provided with spring 11 No. two between outer floater 3 and No. two backup pads 9, and spring 11 No. two runs through outer through-hole 7. No. 10 springs and No. 11 springs are vertical direction setting under natural state to No. 10 springs and No. 11 springs set up along a vertical straight line, and outer floater 3 is located the outer through-hole 7 under. When the liquid level in the tank body is not contacted with the outer floating ball 3, the outer floating ball 3 is pressed down due to self weight, the first spring 10 is extruded along the vertical direction, the second spring 11 is stretched along the vertical direction, and at the moment, if the outer floating ball 3 rocks left and right, the outer floating ball 3 can receive the reset force of the first spring 10 and the second spring 11, so that the outer floating ball 3 is positioned under the outer through hole 7 as far as possible. If the water level reaches the outer floating ball 3, the gravity and the buoyancy of the outer floating ball 3 are partially offset, and the first spring 10 and the second spring 11 are gradually reset along the vertical direction. Along with outer floater 3 is located the volume of aquatic and is bigger and bigger, outer floater 3's buoyancy is bigger and bigger, and outer floater 3 continues towards outside through-hole 7 vertical removal, and until outer floater 3 blocks up outer through-hole 7, No. two springs 11 are compressed along vertical direction this moment, and No. one spring 10 is stretched along vertical direction. However, when the outer float 3 tends to move left and right, the second spring 11 and the first spring 10 still counteract each other. In addition, the second spring 11 and the first spring 10 are matched to stably limit the outer floating ball 3 near the outer through hole 7, thereby completing the working process.

In order to further ensure that the outer floating ball 3 is not separated from the outer through hole 7 when the outer floating ball 3 blocks the outer through hole 7, the outer floating ball 3 is selected as a balloon in the embodiment, so that the buoyancy borne by the outer floating ball 3 is as large as possible under the self-gravity of the outer floating ball 3. Outer through-hole 7 department is provided with a horn pipe 12, and a horn pipe 12 is located the casing 1 outside, and a horn pipe 12 sets up towards the casing 1 is outer, and the edge of the opening of a horn pipe 12 and the edge connection of outer through-hole 7. At this time, the opening diameter of the first flared tube 12 far away from the outer through hole 7 is larger than the opening diameter of the first flared tube 12 communicated with the outer through hole 7. When the outer floating ball 3 blocks the outer through hole 7, the outer floating ball 3 can be clamped into the outer through hole 7 through deformation due to good elasticity of the outer floating ball. Before the contact of the liquid level in the tank body and the side wall of the outer cavity 6, the buoyancy borne by the outer floating ball 3 is larger, the more corresponding outer floating ball 3 is clamped into the outer cavity 6 through the outer through hole 7, the outer floating ball 3 can completely block the outer through hole 7, and even if the lower part of the outer floating ball 3 slightly shakes left and right, the airtightness of the outer through hole 7 cannot be influenced because the top end of the outer floating ball 3 is clamped into the outer cavity 6. The first flared tube 12 has a guiding effect on the floating process of the outer floating ball 3, and the diameter of an opening at one side of the first flared tube 12, which is connected with the edge of the outer through hole 7, is small, so that the top end of the outer floating ball 3 can be deformed to block the outer through hole 7. And under the ventilation state of the outer through hole 7, the first trumpet tube 12 has a limiting effect on the outer floating ball 3, and a certain movement allowance is reserved for the outer floating ball 3, so that the long-term stress abrasion of the side wall of the outer floating ball 3 is avoided.

Similar to the working process of the outer floating ball 3, a third supporting plate 13 is arranged in the inner cavity 5 in the embodiment, the third supporting plate 13 is fixed with the isolation plate 4 through a fixing plate 17, a third spring 14 is arranged between the third supporting plate 13 and the inner floating ball 2, and the third spring 14 penetrates through the inner through hole 15. The third spring 14 limits the inner floating ball 2 near the inner through hole 15. When the inner floating ball 2 is separated from the inner through hole 15, the third spring 14 is stretched along the vertical direction, so that the inner floating ball 2 is far away from the inner through hole 15 as far as possible, and the air circulation state at the inner through hole 15 is maintained. If water accidentally enters the outer cavity 6 and contacts the inner floating ball 2, the buoyancy and the self gravity borne by the inner floating ball 2 are gradually offset, the inner floating ball 2 vertically moves upwards until the inner through hole 15 is blocked, and the water is ensured not to enter the inner cavity 5 from the outer cavity 6.

Preferably, the inner floating ball 2 is a balloon, the outer cavity 6 is internally provided with a second flared tube 18, the second flared tube 18 is arranged towards the outside of the inner cavity 5, and the opening edge of the second flared tube 18 is connected with the edge of the inner through hole 15. The action mode of the second trumpet tube 18 on the inner floating ball 2 is similar to that of the first trumpet tube 12 on the outer floating ball 3, and therefore the detailed description is omitted.

In addition, for not restricting the flow of air and water, No. one backup pad 8, No. two backup pads 9 and No. three backup pads 13 are the fretwork setting in this embodiment to supply air and water to flow.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
