Abstract
The utility model discloses a fast-connection clamping type filter which is simple in structure. According to the fast-connection clamping type filter, a filter cartridge can be conveniently and quickly replaced. The fast-connection clamping type filter comprises a top cover, a seal ring, a filter drum and the filter cartridge, wherein the filter cartridge is mounted in the filter drum; a plurality of inner clamping positions, which bend inwards, are formed in an open end of the top cover at intervals; the inner wall of the top cover bends inwards along a radial direction to form a circular clamping slot; the seal ring is mounted in the clamping slot; a plurality of outer clamping positions, which bend outwards, are formed in an open end of the filter drum at intervals; the positions of the outer clamping positions correspond to the positions of the inner clamping positions in the same group; the top cover is connected with the filter drum in a sealing manner through clamping fit between the groups of inner clamping positions and outer clamping positions; the inner diameter of the seal ring is a little smaller than that of the end of the opening of the filter drum; the outer diameter of the seal ring is a little smaller than that of the end of the opening of the filter drum; when the top cover and the filter drum are clamped together, the end of the opening of the filter drum squeezes the seal ring upwards; the seal ring is a Y-shaped seal ring, the vertical axial section of the seal ring is obliquely Y-shaped, and the opening of the Y-shaped seal ring points to a central position.
Description
Technical field
The utility model relates to a kind of filter, specifically, relate to a kind of simple in structure, convenient and swift more renew cartridge connect soon clamping type filter.
Background technology
Current filter is on the market to be assembled by top cover, filter cylinder, ring-type O shape circle and filter core substantially, filter core is fixedly mounted in filter cylinder, between filter cylinder and top cover, the general screw-type that adopts is tightened or with fastening flange screw, in disassembly process, need to use special wrench, quite inconvenient and easily leak, and when screw-type overtorquing or when excessive with fastening flange screw, not professional treatment engineer and use professional tool to be difficult to mounting or dismounting; In addition, when needs are more when renew cartridge or dismounting for the second time, ring-type O shape circle can be because press to obtain tension and deforming last time, thereby affect the sealing effectiveness between filter cylinder and top cover, and cause in use procedure leaking, and can only change ring-type O shape to enclose, and causes waste.
Utility model content
For above deficiency, it is a kind of simple in structure that the utility model provides, convenient and swift more renew cartridge connect soon clamping type filter, it comprises top cover and the filter cylinder that removable seal links together, and be fixed on the filter core in described filter cylinder, the open end of described top cover is arranged at intervals with the interior screens of several inside bendings, the open end of filter cylinder corresponding described in each in card bit position the outer screens of outside bending is set respectively, in each group, between screens and outer screens, adopt the mode of buckle to realize being tightly connected of top cover and filter cylinder.
In order further to realize the utility model, the inwall of described top cover prolong its radially inwardly bending be formed with the draw-in groove of a loop, in described draw-in groove, be provided with sealing ring, in the time that top cover is connected with filter cylinder, upwards crush seal circle of the end circle wall of filter cylinder.
In order further to realize the utility model, the longitudinal axis cross section of described sealing ring is the Y type being obliquely installed, and its opening points to center.
In order further to realize the utility model, the internal diameter of described sealing ring is slightly less than the internal diameter of the end of the opening of filter cylinder.
The beneficial effects of the utility model:
1, the open end of top cover of the present utility model and filter cylinder is provided with respectively interior screens and the outer screens that array cooperatively interacts, when dismounting, need only and rotate top cover, make interior screens and wild card dislocation open a low-angle, filter cylinder just can take out, domestic consumer oneself is in and just can directly takes apart, laborsaving and convenient.
2, sealing ring of the present utility model adopts y-type seal ring, in filter, during without tap water pressure, can arbitrarily unclamp or screw top cover; Have tap water pressure in filter time (filter work), sealing ring can expand, and its opening can slowly magnify, until be close to respectively the inwall of filter cylinder and top cover, makes the better tightness between top cover and filter cylinder.
3, filter overall structure of the present utility model is simple, safe and practical, and low cost of manufacture is convenient for installation and maintenance, without the advantage such as professional and technical personnel and special dismantling device, suits large area to popularize.
Accompanying drawing explanation
Fig. 1 is the structural representation that connects soon clamping type filter of the present utility model;
Fig. 2 is the structural representation of top cover of the present utility model;
Fig. 3 is the structural representation of filter cylinder of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, wherein, direction of the present utility model is take Fig. 1 as standard.
As shown in Figure 1, Figure 2 and Figure 3, the clamping type filter that connects soon of the present utility model comprises top cover 1, sealing ring 2, filter cylinder 3 and filter core 4, filter core 4 is arranged in filter cylinder, the open end of top cover 1 is formed with the interior screens 11 of several inside bendings, each interior screens 11 is spacedly distributed at the open end of top cover 1, the inwall of top cover 1 prolongs its radially inside bending and is formed with the circular draw-in groove of a circle 12, sealing ring 2 is arranged in this draw-in groove 12, the external diameter of sealing ring 2 is slightly larger than the external diameter of draw-in groove 12, to sealing ring 2 is stuck in draw-in groove 12.The open end of filter cylinder 3 is formed with the outer screens 31 of several outside bendings, each outer screens 31 is spacedly distributed at the open end of filter cylinder 3, and the outer screens 31 of each group is corresponding with the position of interior screens 11, between top cover 1 and filter cylinder 3, utilize the realization that is clasped of the interior screens 11 of array and outer screens 31 to be tightly connected.The internal diameter of sealing ring 2 is slightly less than the internal diameter of the end of the opening of filter cylinder 3, the external diameter of sealing ring 2 is slightly less than the internal diameter of the end of the opening of filter cylinder 3, in the time that top cover 1 and filter cylinder 3 are fastened togather, the end of the opening of filter cylinder 3 is crush seal circle 2 upwards, wherein, sealing ring 2 of the present utility model is paid the utmost attention to employing y-type seal ring, and its longitudinal axis cross section is the Y type being obliquely installed, and its opening points to center.
Like this, in the time having hydraulic pressure in filter, sealing ring 2 starts to expand, its opening slowly magnifies, thereby be close to respectively the inwall of filter cylinder 3 and top cover 1, make the better tightness between top cover 1 and filter cylinder 3, in the time there is no hydraulic pressure in filter, can arbitrarily unclamp and screw top cover 1, in utilizing, screens 11 misplaces and top cover 1 and filter cylinder 3 is separated with outer screens 31.
The foregoing is only preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, in implementation process, may there is local small structural modification, if various changes of the present invention or modification are not departed to the spirit and scope of the present invention, and within belonging to claim of the present invention and equivalent technologies scope, the present invention is also intended to comprise these changes and modification.
