Abstract

The utility model relates to a multi-functional water filter, composed of a movable joint, a rotary joint and a water tap. The outer sleeve of the water tap can be moved up and down to change the water into column shape or spraying shape, the rotary joint can change the direction of the water tap with a plurality of angles, and the movable joint composed of a big and small soft pipe, claw-shaped hard pipe and an outer nut, results in the firm connection of the water filter and a water supply pipe. The utility model has the functions of changing the direction and the mode of the sprayed water, preventing the water from splashing, and filtering, is provided with artful design and compact structure with low cost, and is an ideal small article used in daily life at home.

Description

Multi-functional water filter

The utility model relates to a kind of device that influences liquid flow, particularly a kind of multi-functional water filter of convertible water outlet streamflow regime.

By a kind of multi-functional water filter of the design people design, formed by articulation, swivel head and tap three big parts, have splashproof, filtration, multi-angle function such as change direction.In my early stage product design, articulation is a clamp type, promptly outside a flexible pipe (this pipe box is received on the water pipe), put a split coupling, there is pair of flanges at the ferrule openings place, clamp this to flange with screw, caliber is dwindled, grip both hose, thereby closely be socketed in flexible pipe on the water pipe, unclamp screw, can take off again, reach the purpose of flexible connection.This clamp type articulation, each position is stressed irregular during clamp, and two flanges of opening part need design thicklyer, and in order to avoid split, whole joint itself is not the center symmetry just, and it is also not quite convenient to use.On the screw during tension, stress raiser may explosion; Twist tightly inadequately, can overlap not firmly again, make water filter get loose, perhaps leak.

The purpose of this utility model is to avoid weak point of the prior art and a kind of easy to connect, firm, water filter with multiple function of not leaking is provided.

The purpose of this utility model can reach by following measure:

The utility model water filter also by articulation, execute rotary head and three parts of tap are formed.Wherein, articulation is made up of big flexible pipe, claw-like hard tube and big nut, and one is being overlapped one.Big flexible pipe is made by flexible plastic, can be divided into big or small two-stage pipeline section, and bigger epimere pipe is tapered, and the water pipe external diameter at its internal diameter and water source is suitable, is advisable being set on the water pipe.Also 1～2 the little flexible pipe that is equipped with in addition can be inserted in wherein, to adapt to different behaviours in service.The less hypomere Guan Ze of big flexible pipe is nested in the claw-like hard tube, and in its bottom the flanged prominent plane of turning up is arranged, and becomes the end face seal packing ring of hard tube.On the claw-like hard tube conical pipe in the top, be furnished with the alternate pawl bar of thickness, make it have certain telescopic resilience, as one " pawl ", be enclosed in its peripheral big nut when compressing, " pawl " can slightly inwardly shrink, compress the big flexible pipe that is enclosed on its inwall, thereby make big flexible pipe closely entangle water pipe equably, it is firm to connect, and stops to reveal.The stage casing of hard tube is an external screw thread, matches with the internal thread of big nut, and the external screw thread of hypomere then matches with the internal thread of swivel head.The inwall of big nut has screw thread, and outer surface is done waviness, increases frictional force when being convenient to water and pinching.

Swivel head is the intermediate member that connects articulation and tap, again can multi-faceted universal rotation, make the water outlet direction random variation of tap.It is connected with tap with articulation respectively with the thread connecting mode two ends.Swivel head is made up of circle shaven head, the bare headed nut of circle, cushion rubber, headgear and rubber cushion.One end of circle shaven head has internal thread, can screw in the external screw thread of claw-like hard tube, and the outer surface of the other end is a sphere except that the hollow water channel, can rotate freely on the inner surface of headgear, and the junction seals with cushion rubber.Headgear is tucked within the bare headed nut of circle, is spun by this nut and tap, centrally plays the flat seal effect with rubber cushion.

The tap parts comprise the grid that filters usefulness, the movement of valve that plays shunting action and movable sleeve, overcoat, big cushion rubber, gondola water faucet and gondola water faucet headgear etc.Overcoat is enclosed within the gondola water faucet periphery, and the gondola water faucet headgear then is enclosed within the gondola water faucet, the segment distance that can vertically relatively move between overcoat and the movable sleeve, and an end of movable sleeve is threaded with the bare headed nut of circle.When overcoat is vertically left behind, current be directed to through the guiding weir gondola water faucet folder outer ring annular groove, be emitted into the gondola water faucet shape and when overcoat makes progress pushed home through the aperture one by one of bottom of trench, central movement of valve blocks the path of flow direction annular groove with its flat board, and can only be from the orifice flow on the flat board to central authorities, again through the porous plate of gondola water faucet headgear, lower hydraulic pressure, become water column to flow out.

The utility model water filter has following advantage:

1, diverse in function is variable.Except that splashproof, filtration, multi-angle were changed direction, the also convertible water-out manners of this water filter or one-tenth water column or gondola water faucet shape need only move up and down overcoat and get final product.

2, safe firm with connecting of feed pipe.Adopt the connected mode of this articulation.Use very conveniently, impact, also can not make water filter come off from water pipe even be subjected to hydraulic pressure.

Description of drawings: Fig. 1 is the cutaway view of the utility model water filter, Fig. 2 is the cutaway view of big flexible pipe, Fig. 3 is the cutaway view of claw-like hard tube, Fig. 4 is the longitudinal section of big nut, and Fig. 5 is its vertical view, and Fig. 6 is the half sectional view of circle shaven head, Fig. 7 is its vertical view, Fig. 8 is the cutaway view of movement of valve, and Fig. 9 is the half sectional view of gondola water faucet, and Figure 10 is its sectional elevation.Among each figure, the 1, the 2nd, little flexible pipe, the 3rd, big flexible pipe, the 301st, the conical section of big flexible pipe, the 302nd, its hypomere, the 303rd, its prominent plane.The 4th, big nut, the 401st, its internal thread, the 402nd, the outer of big nut, the 5th, claw-like hard tube, the 501st, pawl, the 502nd, the urceolus position of hard tube, the 5021, the 5022nd, external screw thread, the 6th, circle shaven head, the 601st, the thread segment, the 602nd of circle shaven head, its round end section, the 7th, the bare headed nut of circle, the 8th, cushion rubber, the 9th, headgear, the 10th, rubber cushion, the 11st, grid, the 12nd, movement of valve, the 121st, the aperture of movement of valve, the 122nd, the flat board of valve, the 13rd, movable sleeve, the 14th, big cushion rubber, the 15th, overcoat, the 16th, gondola water faucet, the 161st, bottom of trench aperture, the 162nd, guiding weir, the 163rd, annular groove.

Embodiment: as shown in drawings, be assembled into articulation by big flexible pipe 3, big nut 4, claw-like hard tube 5.Be assembled into swivel head by circle shaven head 6, the bare headed nut 7 of circle, cushion rubber 8, headgear 9, cushion rubber 10.By grid 11, movement of valve 12, movable sleeve 13, big cushion rubber 14, overcoat 15, gondola water faucet 16, gondola water faucet headgear 17 is assembled into tap.With above-mentioned articulation, three parts of swivel head and tap are screwed in together with thread connecting mode, just constitute the multi-functional water filter of the utility model again.
