Water purifier by filter core, make the water that polluted by cleaning to producing, the needed state of living, namely make water reach certain cleanliness factor, therefore, filter core is the core component of water purifier.The sealing property of filter element shell directly has influence on the use of water purifier, if sealing property is bad, water purifier there will be drainage.But, filter element shell simple in structure is formed by two and half shell combination conventionally, and because two and half housings can exist scale error when producing, error can affect the sealing property of housing slightly greatly, although therefore this type of filter element shell is simple in structure, yield rate is not but very high.In addition, the insecure filter core of sealing property obviously can strengthen the risk that water purifier leaks.。
Utility model content
The purpose of this utility model is to provide the extraordinary water purifier filter element shell of a kind of sealing property, the impact of the scale error of reduction by two and half housings on housing seal performance.
The technical scheme that realizes the utility model object is: a kind of water purifier filter element shell, comprises the first half housings, the second half housings, water inlet and delivery port; The opening end of described the first half housings is provided with external screw thread; Described the second half housing opening ends are provided with the internal thread being threaded with the opening end external screw thread of the first half housings; Described water inlet is arranged on the first half housings or the second half housings; Described delivery port is arranged on the first half housings or the second half housings; Also comprise sealing ring; Described the first half shell end are provided with short annulus, and the outside of the root of this short annulus is provided with the first planar annular perpendicular to the external cylindrical surface of short annulus; Described sealing ring be enclosed within on the external cylindrical surface of short annulus and with the first annular plane contact; The inner side of described the second half housings is provided with and the external cylindrical surface of the first half housings and the first planar annular corresponding parallel inner cylinder face and the second planar annular respectively near the position of internal thread root; After described the first half housings and the second half housing assemblings, the inner cylinder face of the external cylindrical surface of sealing ring and the first half housings and the first planar annular and the second half housings all contacts with the second planar annular.
Described sealing ring is O-ring seals.
The root of the internal thread of described the second half housings is axial symmetry.
Described the first half housings and the second half housings all adopt plastic material.
The material of described the first half housings and the second half housings all adopts polypropylene or nylon or PETG.
The internal thread of the external screw thread of described the first half housings and the second half housings is trapezoidal thread or is buttless thread.
Adopted technique scheme, the utlity model has following beneficial effect: (1) sealing ring of the present utility model can compensate the scale error between the first half housings and the second half housings, thereby reduce the impact of scale error on housing seal performance, promote the sealing effectiveness between the first half housings and the second half housings.
(2) sealing ring of the present utility model is O-ring seals, O-ring seals is larger in the sectional dimension of tightening in pressurized direction, thereby strong to the compensation ability of scale error, after O shape circle pressurized, can expand in the direction generation vertical with tightening pressurized direction simultaneously, after O shape circle expands, can be close to the face of cylinder of both sides and further enhanced leaktightness effect.
(3) the utility model can improve by strengthening pretightning force the sealing property of O-ring seals.
(4) root of the internal thread of the second half housings of the present utility model is axial symmetry, so this part entity can obtain by the method for rotation longitudinal section when mapping; Short annulus due to the first half shell end is also axisymmetric shape again, so, the working of plastics of producing for injection moulding process is easily controlled the deflection of the material adjoining with sealing ring, easily control its roundness tolerance, dimensional tolerance and the form and position tolerance of this hermetically-sealed construction are all easily controlled, thereby further improved sealing property of the present utility model.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
