Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the utility model provides a leakage-proof water tank, which comprises a water tank shell 4, a sealing plug 3 and an air inlet structure 2, wherein the sealing plug 3 is arranged on the water tank shell 4, the air inlet structure 2 is arranged by penetrating through the sealing plug 3, and one side of the air inlet structure facing the inside of the water tank shell 4 is protruded out of the sealing plug 3;
Here, as shown in fig. 1 and 2, the portion of the air intake structure 2 protruding from the sealing plug 3 toward the inside of the water tank 4 is not limited to the cylindrical shape shown in the drawings, and may be a polygonal prism, a rectangular parallelepiped, or the like. The terminal surface of gas outlet seals and the middle part disconnection forms gap 31, and when needs admit air, gaseous from the air inlet 33 entering, directly get into in the water tank shell behind the gap 31 of gas outlet, be favorable to timely, stable admitting air, simultaneously, when need not admit air, because gap 31 is less than air inlet 33 far away, consequently can also prevent to leak.
The part protruding from the sealing plug 3 faces the inner side of the water tank 4, the air inlet 33 is positioned on the sealing plug 3, the air outlet is positioned at the free end of the protruding part, the middle part of the end surface of the air outlet is cut off to form a gap 31 (in order to achieve the effect of sealing and preventing water leakage), and when air does not need to be introduced, the end surface of the air outlet can play a sealing effect, namely water does not leak towards the outer side of the water tank; when air is required to be fed, because the convex part is extruded by air pressure, the resistance from the body structure of the sealing plug 3 can not be basically received, the gap 31 at the free end of the convex part can be more easily opened for air feeding, which is beneficial to timely and stable air feeding and water discharging, and meanwhile, the effect of not influencing the water leakage can be achieved.
As shown in fig. 2, in one embodiment, both side outer wall surfaces of the free end of the air intake structure 2 are inclined toward the middle of the free end.
Wherein, because the middle part of the free end of inlet structure 2 forms gap 31, the both sides outer wall face of the free end of inlet structure 2 all inclines towards the gap of free end, inclined plane 32 that inclines forms at the part that inlet structure 2 is located the sealing plug 3 lower extreme, the inclined plane 32 of both sides makes the terminal surface of the free end of inlet structure 2 form and is similar to rectangular shape, gap 31 evenly cuts apart into two parts with this terminal surface from the terminal surface centre of the free end of inlet structure 2, when needs admit air, gaseous directly gets into in the water tank shell behind gap 31, when need not admit air, there is the face that blocks in the free end terminal surface of inlet structure 2, and not link up completely, make the water tank be difficult for leaking.
When air is fed, the side wall of the air inlet structure 2 from the large opening to the slit-shaped opening is gradually thinned due to the action of the two inclined planes 32, and when air is fed, the resistance near the air outlet is gradually reduced, so that the air can smoothly enter the water tank shell, and therefore the two inclined planes 32 also have the function of enhancing the air inlet effect. In addition, the two inclined surfaces 32 can also divide the air inlet structure 2 into a large opening (one end on the sealing plug 3) and a slit-shaped opening (one end under the sealing plug 3, namely a free end), so that when the same amount of gas enters one side of the slit-shaped opening, the larger impact pressure can be generated on the inner wall surface of the slit-shaped opening, and the slit-shaped opening is also favorable for opening the slit-shaped opening for air inlet.
In one embodiment the air inlet structure 2 is integrated with a sealing plug 3, which sealing plug 3 is arranged at the upper end surface of the water tank.
The air inlet structure 2 and the sealing plug are integrally formed, so that the air inlet structure can be better and stably fixed on the sealing plug, when a water pump pumps water from the water tank and air needs to be introduced into the water tank, air can be pressed into one side of the slit-shaped orifice from one side of the large orifice, and finally the slit-shaped orifice is opened; when no air is required to enter the water tank, the slit-shaped orifice is much smaller than the large orifice, so that water in the water tank is not easy to leak from the air inlet structure 2.
