Embodiment
Please refer to Fig. 1 to Fig. 4, the vacuum suppresser that the embodiment of the invention provides, it comprises connection set 30, Seal cage 10 and shell 20.Seal cage 10 is connected with shell 20 with connection set 30.
The chamber wall of Seal cage 10 is provided with air valve, and air valve comprises valve body 13 and spool 14.Valve body 13 communication seals chamber 10 and space outerpaces.Spool 14 matches with valve body 13, is used for the Push And Release of control valve body 13.In the present embodiment, the space outerpace of Seal cage 10 is shell 20, is formed with air passageways 21 in the shell 20, valve body 13 communication seals chambeies 10 and air passageways 21.In other embodiments, shell 20 also can omit, and at this moment, valve body 13 directly is communicated with outside atmosphere.
Be provided with the inner float ball 11 that can float on the water in the Seal cage 10, inner float ball 11 is connected with spool 14, and inner float ball 11 drives spool 14 valve body 13 when float state, drives spool 14 and open valve body 13 when full state.
Please in the lump with reference to figure 2, particularly, valve body 13 comprises outer valve 131, inner valve body 132 and dividing plate 133, outer valve 131 is communicated with space outerpace, inner valve body 132 is communicated with Seal cage 10, and dividing plate 133 cuts off outer valve 131 and inner valve body 132, offers the valve opening 134 that is communicated with outer valve 131 and inner valve body 132 on the dividing plate 133, spool 14 is arranged in the inner valve body 132 movably, and can open or stop up valve opening 134.Further, the end opening that inner valve body 132 and dividing plate 131 are relative then is provided with air outlet hole 135 on the sidewall of inner valve body 132.In the time of in spool 14 is housed in inner valve body 132 fully, valve opening 134 is stopped up, make air enter inner valve body 132 from outer valve 131.And when spool 14 stretched out from the open end portion of inner valve body 132 under the drive of inner float ball 11, valve opening 134 was opened, and this moment, air can enter in the Seal cage 10 by outer valve 131, valve opening 134, air outlet hole 135.
In a preferred embodiment, valve body 13 is provided with connecting base 136, and inner float ball 11 is connected by connecting rod 12 with spool 14, and connecting rod 12 is hinged on the connecting base 136, and the one end connects spool 14, and the other end connects inner float ball 11.Connecting rod 12 is specially a bent stick, and its curved part is hinged on the connecting base 136.Further preferably, the articulating point of connecting rod 12 apart from the distance of inner float ball 11 greater than the distance of articulating point apart from spool 14.So, inner float ball 11 can more easily drive spool 14 and moves.
Please refer to Fig. 4, this vacuum suppresser is connected on the outside water pot 40 by connection set 30 in use.The top of outside water pot 40 is provided with the opening (figure is mark) that matches with connecting passage 32 on the connection set 30, also is provided with outer ball float 41 in the outside water pot 40.When intaking in the outside water pot 40, outer ball float 41 floats under the buoyancy of water effect.When water reach a certain height, outer ball float 41 withstood seal ring 33.But the pressure in the at this moment outside water pot 40 is still not enough, water level continues to rise, and finally enters in the Seal cage 10 through connecting passage 32, and inner float ball 11 rises under the buoyancy of water effect, drive spool 14 and move and stop up valve opening 134, this moment, air can't enter in the enclosed cavity 10 again.
When being connected with outside water pot 40, other consersion units that draw water from outside water pot 40 are when normal operation, if the intake pipe of outside water pot 40 is cut off the water, consersion unit is very fast at this moment takes the water in the outside water pot 40 away, water level in the outside water pot 40 descends rapidly, make outer ball float 41 and inner float ball 11 under the gravity effect, fall, be that inner float ball 11 is in full state, it drives spool 14 and stretches out from the open end portion of inner valve body 132, valve opening 134 is opened, valve body 13 is in open mode, outside air is through air-flow path 21, outer valve 131, valve opening 134, inner valve body 132, air outlet hole 135 enters in the Seal cage 10, and in connecting passage 32 enters outside water pot 40, thereby can prevent that this outside water pot 40 from forming vacuum state and being inhaled flat.
The inner float ball of vacuum suppresser provided by the invention is externally controlled air valve under the water level effect of water pot, when the water level of outside water pot hangs down, inner float ball is opened air valve, make outside air to enter in the outside water pot through Seal cage, thereby prevent outside water pot from forming vacuum state and inhaled flat.
Specific embodiment described herein only is that the present invention's spirit is illustrated.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as water pot, Seal cage, inner float ball, outer ball float, connecting rod morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
