Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 1-6, a durable water purifying faucet comprises a T-shaped switch main body 1, a water outlet cavity 13 is formed in the upper end of the switch main body 1, a water inlet cavity 11 is formed in the lower end of the switch main body 1, the middle of the switch main body 1 extends outwards to form a water passing cavity 12, a valve core is arranged in the water passing cavity 12, and the valve core controls the connection and disconnection between the water passing cavity 12 and the water inlet cavity 11 as well as between the water outlet cavities 13. The lower extreme of switch main part 1 can be dismantled and connect into water mechanism 5, the upper end of switch main part 1 can be dismantled and set up out water mechanism 4. The upper end of the switch main body 1 is in threaded connection with a locking nut 3, a water outlet mechanism 4 penetrates through the locking nut 3 and is inserted into an upper end opening of the switch main body 1, and the water outlet mechanism 4 is inserted into the outer periphery of one end in the switch main body 1 and is sleeved with a protective ring 2.

Referring to fig. 1 and 2, the guard ring 2 includes: the locking nut 3 and the switch main body 1 are sleeved with an upper guard ring 23 on the periphery of the water outlet mechanism 4, a lower guard ring 22 on the periphery of the water outlet mechanism 4 is arranged below the upper guard ring 23 in a sleeved mode, the outer wall of the lower guard ring 22 abuts against the inner wall of the switch main body 1, and a plurality of O-shaped rings 21 arranged on the periphery of the water outlet mechanism 4 are further arranged below the lower guard ring 22 in a sleeved mode.

Because the O-shaped ring 21 is not needed to be used as a connecting piece of the switch main body 1 and the water outlet mechanism 4, and is only used as a sealing piece for installation, the maximum static friction between the O-shaped ring 21 and the inner wall of the switch main body 1 is smaller than that of a traditional water purification faucet, the abrasion of the O-shaped ring 21 is smaller, the service life of the O-shaped ring 21 is prolonged from 40000-50000 times to 75000-85000 times, and the improvement efficiency is obvious.

Referring to fig. 1 to 3, the water outlet mechanism 4 includes a water outlet pipe 41, an insertion pipe 42 is integrally formed at a lower end of the water outlet pipe 41, a plurality of annular grooves 422 are formed at intervals at a lower end of the insertion pipe 42, and the annular grooves 422 are internally provided with O-rings 21 in a matching manner. An installation groove 421 is formed above the annular groove 422, and the lower protective ring 22 is arranged in the installation groove 421.

Referring to fig. 1, 2, 4 and 5, in the conventional water purifying faucet, the water outlet mechanism 4 is directly inserted into the switch body 1 and is locked and sealed with the lock nut 3 by the upper protection ring 23, so that the water outlet mechanism 4 and the switch body 1 are only connected in a sealing manner by the elastic O-ring 21, when the water outlet mechanism 4 bears a large pulling force or water pressure, the water outlet mechanism 4 may be separated from the switch body 1, even when the water outlet mechanism 4 is separated due to an excessive impulse, the initial speed is very high, and potential safety hazards are brought to users. Therefore, as a further improvement, the lower guard ring 22 includes a lower ring body 221, a lower end inner wall of the lower ring body 221 extends inward to form a first step portion 222, the first step portion 222 is fitted in the mounting groove 421, and an upper end inner wall of the lower ring body 221 is fitted in an outer wall of the water outlet pipe 41. The upper protection ring 23 comprises an upper ring body 211, the outer wall of the lower end of the upper ring body 211 extends outwards to form a second step part 212, and the second step part 212 is embedded in a gap between the locking nut 3 and the switch main body 1. Wherein, the upper end surface of the lower ring body 221 abuts against the lower end surface of the upper ring body 211. This makes water outlet mechanism 4 appear keeping away from when the motion trend of switch main part 1, can drive down guard ring 22 and move towards the direction of keeping away from switch main part 1, and guard ring 23 is extruded to lower guard ring 22 this moment, and last guard ring 23 is blockked by lock nut 3, has avoided the condition that water outlet mechanism 4 deviates from.

Referring to fig. 6, if the whole inner diameter of the water outlet cavity 13 is the same or the inner diameter of the upper end of the water outlet cavity 13 is smaller than the inner diameter of the lower end, the lower protection ring 22 needs to be in press fit with the water outlet cavity 13, otherwise, the water outlet mechanism 4 moves up and down in the water outlet cavity 13 due to self gravity and water pressure, so that the abrasion of the O-ring 21 and the lower protection ring 22 is increased, which is inconsistent with the original intention of prolonging the service life of the water purification faucet. Therefore, as a further improvement, the water outlet cavity 13 includes an insertion part 131 with an inner diameter identical to the outer diameter of the insertion tube 42, and the inner diameter of the insertion part 131 near the opening is enlarged to form a clamping part 132. The annular groove 422 is located in the insertion part 131, and the mounting groove 421 is located in the clamping part 132. At this time, the lower protection ring 22 only needs to have an outer diameter larger than the inner diameter of the insertion portion 131, and does not need to be in transition fit or interference fit with the clamping portion 132. Furthermore, when the water outlet mechanism 4 rotates, friction cannot occur between the water outlet mechanism and the switch main body 1, and friction is generated between the water outlet mechanism and the O-shaped ring 21 or the upper protective ring 23 and the lower protective ring 22, so that noise generated when the water outlet mechanism 4 rotates is reduced, and the service lives of the O-shaped ring 21, the upper protective ring 23 and the lower protective ring 22 are prolonged.

Referring to fig. 4, in order to facilitate the replacement of the lower guard ring 22, as a further modification, the lower ring body 221 is provided with a fitting opening 223 which is wide at the top and narrow at the bottom along the longitudinal direction.

Referring to fig. 4, as a further modification, the first step portion 222 is radially provided with relief holes 224. The lower guard ring 22 is required to bear the torsional shear force generated when the water outlet mechanism 4 rotates, in addition to the axial pressure after the switch is started. If the relief hole 224 is not formed, the service life of the lower protective ring 22 is reduced, and the purpose of prolonging the service life of the water purifying faucet cannot be achieved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
