Abstract
The utility model discloses an exhaust port used for a water tank and belongs to the field of water tank equipment. The exhaust port used for the water tank comprises an exhaust port body, external threads are arranged on the lower portion of the exhaust port body, a first limit flange is arranged in the middle of the exhaust port body, a second limit flange is arranged at the upper portion of the exhaust port body, and external threads are arranged on the top of the exhaust port body and matches with a cover which is provide with internal threads. The exhaust port used for the water tank is characterized in that a breathable membrane is arranged between the cover and the second limit. Due to the adoption of the technical scheme, air pressure in the inner portion of the water tank is capable of being communicated with the outside through a breathable groove of the breathable membrane, pressure of the inner portion of the water tank is balanced with the outside pressure, pollutions can not enter the water tank through the breathable groove and sanitation of water quality can be guaranteed.
Description
Technical field
The utility model relates to the water tank apparatus field, particularly a kind of exhaust opening for water tank.
Background technology
At present, all can be provided with an exhaust opening on the water tank, exhaust opening is generally the ventilative pipeline in a two, one end of exhaust opening is communicated with water tank, the other end of stack is positioned at the water tank outside and is communicated with outside air, so just can guarantee pressure and extraneous pressure balance in the water tank, make water tank normal operation retaining.But do not carry out corresponding Protection, like this, will be so that airborne pollutant enters into water tank, cause simultaneously the pollution of the water that we drink, in the course of time, will jeopardize our health.
In sum, for deficiency and the defective of existing water tank, need especially a kind of pollutant that can prevent to enter into the exhaust opening that water tank can make again water tank inside be communicated with outside air, address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of water tank inside that can make to be communicated with, to prevent that with outside air pollutant from entering the exhaust opening of water tank, remedies shortcomings and deficiencies of the prior art.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of exhaust opening for water tank, comprise the exhaust opening body, the bottom of described exhaust opening body is provided with external screw thread, the middle part is provided with the first spacing rib, top is provided with the second spacing rib, the top of described exhaust opening body be provided with external screw thread and with one female lid be set be used in conjunction with, it is characterized in that, be provided with ventilated membrane between described lid and the described second spacing rib.
Preferably, described ventilated membrane is circular, circumferentially is arranged at intervals with some ventilative grooves on the described ventilated membrane.
Preferably, the width of described ventilative groove is 4mm.
Preferably, the soffit at described the first spacing rib is provided with rubber washer.
Owing to having adopted above-mentioned technical scheme, the air pressure of water tank inside can be in communication with the outside by the ventilative groove of ventilated membrane, makes the pressure balance in the interior pressure of water tank and the external world, and pollutant can not enter in the water tank from ventilative groove, has guaranteed the health of water quality.
Description of drawings
Fig. 1 is the structural representation of a kind of exhaust opening for water tank of the utility model.
Fig. 2 is the I place enlarged drawing of Fig. 1.
Fig. 3 is the top view of ventilated membrane.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Extremely shown in Figure 3 referring to Fig. 1, a kind of exhaust opening for water tank comprises exhaust opening body 10, the bottom of exhaust opening body 10 is provided with external screw thread 13, the middle part is provided with the first spacing rib 11, and top is provided with the second spacing rib 12, and the external screw thread 13 of exhaust opening body 10 bottoms is threaded connection with the connector of water tank, by the first spacing rib 11 spacing screwing, the soffit place mat of the first spacing rib 11 rubber washer, the water of water tank inside can not leaked, tightness is good.
The top of exhaust opening body 10 is provided with external screw thread, lid 20 is provided with internal thread, the top of lid 20 by being screwed at exhaust opening body 10 is until conflict with the second spacing rib 12, place mat has the circular ventilated membrane 14 of one deck between lid 20 and the second spacing rib 12, circumferentially being arranged at intervals with some width on the ventilated membrane 14 is the ventilative groove 14a of 4mm, so that the air pressure of water tank inside can be in communication with the outside by ventilative groove 14a, make the pressure balance in the interior pressure of water tank and the external world, prolong the application life of water tank; Ventilated membrane 14 place mats can prevent that pollutant from entering in the water tank between lid 20 and the second spacing rib 12 simultaneously, have guaranteed the health of water quality in the water tank.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
