Description

Anti-drop's external filter

Technical Field

The utility model relates to a filter technical field, in particular to anti-drop's external filter.

Background

The external nut of the existing external filter usually adopts an internal bolt to connect one end of the nut with the filter body by screw thread, and the other end of the nut is connected with external water outlet equipment such as a water valve or a shower head, so that the connection of the filter and the external equipment is realized.

The utility model adopts the following technical scheme:

the utility model provides an anti-drop's external filter, includes body, filter house, buckle and external nut, the body is equipped with water inlet, circulation chamber, drainage mouth and delivery port, the delivery port upper end is equipped with the draw-in groove, and the lower extreme is equipped with the spacing ring, the buckle is one end open-ended annular elastomeric element, the inside arch of buckle lower extreme forms first bulge loop, first bulge loop cooperation embedding in the draw-in groove, external nut down is equipped with internal thread and second bulge loop from last, when external nut up lifts, the buckle is right the second bulge loop carries on spacingly, when external nut down pressed, the second bulge loop supports on the spacing ring.

Preferably, the filter house is equipped with knob, buckle, sealing washer and filter core from the extroversion inwards, knob, buckle and filter core integrated into one piece, the sealing washer cover is established the buckle with between the filter core.

Preferably, the inner side of the water filtering port is symmetrically provided with clamping blocks matched with the buckles, and the outer side of the water filtering port is provided with a corresponding window.

Preferably, the filter part and the water filtering port are connected in a snap-fit manner through the snap and the clamping block, and the filter part can be rotatably installed or withdrawn from the water filtering port.

Preferably, the number of the sealing rings of the filter part is 2.

After the technical scheme is adopted, compared with the background art, the utility model, have following advantage:

the utility model discloses before the use, external nut down presses down, supports on the spacing ring of delivery port through the second bulge loop, during the use, presses down the buckle and installs on the draw-in groove, rotatory external nut and external parts are like threaded connection such as gondola water faucet, and external nut slowly rises at the in-process of screwing, and during the installation was accomplished, the buckle just offsets with the second bulge loop, realizes spacing to the second bulge loop to prevent coming off and becoming flexible of external nut, avoided the production of the phenomenon of leaking.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 5, an anti-drop external filter includes a body 1, a filtering portion 2, a retaining ring 3, and an external nut 4, where the body 1 is provided with a water inlet 11, a circulation chamber 12, a water filtering port 13, and a water outlet 14, the upper end of the water outlet 14 is provided with a clamping groove 141, the lower end of the water outlet is provided with a limiting ring 142, the retaining ring 3 is an annular elastic component with an opening at one end, the lower end of the retaining ring 3 protrudes inward to form a first protruding ring 31, the first protruding ring 31 is embedded into the clamping groove 141 in a matching manner, the external nut 4 is provided with an internal thread 41 and a second protruding ring 42 from top to bottom, when the external nut 4 is lifted up, the retaining ring 3 limits the second protruding ring 42, and when the external nut 4 is pressed down, the second protruding ring 42 abuts against the limiting ring 142.

The filter part 2 is provided with a knob 21, a buckle 22, a sealing ring 23 and a filter element 24 from outside to inside, the knob 21, the buckle 22 and the filter element 24 are integrally formed, and the sealing ring 23 is sleeved on the buckle 22 and between the filter elements 24.

The inner side of the water filtering port 13 is symmetrically provided with a block 131 matched with the buckle 22, and the outer side is provided with a corresponding window 132.

The filter part 2 and the water filtering port 13 are in snap connection through the snap 22 and the block 131, and the filter part 2 can be installed or withdrawn from the water filtering port 13 through rotation.

The number of the sealing rings 23 of the filter part 2 is 2, which is used for preventing the filter part 2 from water seepage.

Before using, external nut 4 is down pressed, supports on the spacing ring 142 of delivery port 14 through second bulge loop 42, during the use, installs buckle 3 earlier, down presses the buckle 3 and installs on draw-in groove 141, hear "click" sound and show that buckle 3 installation is successful promptly, rotatory external nut 4 and external part are like threaded connection such as gondola water faucet, and external nut 4 slowly rises at the in-process of screwing, when external nut 4 and external part installation were accomplished, buckle 3 just offsets with second bulge loop 42, realizes spacing to second bulge loop 42 to prevent droing and becoming flexible of external nut 4, avoided the production of the phenomenon of leaking. In addition, filter house 2 and rate mouth of a river 13 buckle are connected, can conveniently look over through window 132 whether chucking of buckle 22 and fixture block 131, and filter house 2 is through rotatory installation or withdraw from mouth of a river 13, convenient dismantlement and washing for filter house 2 can use repeatedly, resources are saved reduces the consumptive material.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
