Description

TECHNICAL FIELD

The present invention relates to the field of a jet regulator, particularly for the bathroom.

STATE OF THE ART

In order to have a uniform shape, color and texture with the faucet, shower and other water supply devices in appearance, and to meet the connection strength requirements at the connection points of the water supply devices, the existing aerators are generally additionally equipped with a shell structure on the periphery of the inner lining of the aerator, and the shell structure is generally made of surface-treated copper, stainless steel or ABS plastic, etc., and at the same time, the shell structure is able to rotate in conjunction with the corresponding structure inside the aerator, so that a switchover of the water delivery quantity is realized.

For example, a Chinese patent document discloses a water outlet device and a washbasin faucet for its application (Publication No CN 216789313U ), with special reference to its cylindrical shell 13, in the patent document, the cylindrical shell 13 uses the vertical guide groove and recess formed on the inner wall, which fit with the vertical limiting block and the horizontal projection, respectively, so that the cylindrical shell is clamped with the outlet pipe body can be used to drive the outlet pipe body to rotate, in this way switching the water delivery amount is realized. Another example is the Chinese patent document: a dual function switch soda maker ( CN217301711U ), wherein the housing 1 and the water dividing body 2 also adopt a clamping method for fitting together, accordingly, a plurality of clamping grooves 1 must be provided on the inner wall of the housing 1, which cooperate with the projections and the ribs on the outer wall of the water dividing body 2 to pass through the housing to drive the water dividing body to rotate and thus realize the switching of the water delivery quantity.

However, in the case structure in the above-mentioned water outlet device and jet regulator, a larger wall thickness needs to be reserved in the production process as a margin for secondary processing, that is, the wall thickness needs to be reserved for slitting, and the smaller size of this case structure itself leads to a more complicated secondary processing process and higher cost, waste of material occurs and more time is taken, so the shell structure produced after secondary processing leads to increase in cost of the jet regulator.

and wherein the outer wall of the inner liner 2 is provided with limiting ribs 21 and a convex lip 22, and wherein the limiting ribs 21 are distributed along the axial direction of the inner liner 2 and fit into the through groove 11, and wherein the convex lip 22 is at the outlet end of the inner liner 2 is located and presses against the end surface in the 1 axial direction of the cylindrical housing 1.

The working principle of the present invention is as follows: the pipe material used to manufacture the cylindrical housing 1 synchronously forms the through groove 11 when molding, a cylindrical housing 1 provided with the through groove 11 is obtained by cutting with a fixed length, and in cooperation with the limiting ribs 21 and the convex lip 22 causes the inner liner 2 and the cylindrical housing 1 to maintain a relatively stable connection in the circumferential direction and the axial direction.

From the above explanation, it can be seen that the present invention has the following advantages: during the forming process, pipe pieces in the raw material mold synchronously form the through groove 11, and in the cylindrical housing 1 in the present invention, only the pipe pieces need to be cut, and the incision of the cylindrical housing 1 can be manufactured by grinding, at the same time, on the outer wall of the inner liner 2, the positions of the limiting ribs 21 and the convex lip 22 are adaptively adjusted so that the limiting ribs 21 adapt to the through groove 11 to realize that the Inner liner 2 and the cylindrical housing 1 remain relatively stationary in the circumferential direction, in this way, the cylindrical housing 1 can drive the inner liner 2 to rotate, and with the arrangement of the convex lip 22, an axial limitation is realized because in the actual use process of the jet regulator the water outlet opening of the water outlet devices such as the faucet or the shower, at the outlet end of the inner liner 2, the convex lip 22 is arranged, which fits into the water outlet opening of the water outlet device, at the same time, the two ends of the cylindrical housing 1 are limited in the axial direction to to ensure the connection stability between the cylindrical housing 1 and the inner lining 2. In the present invention, it is neither necessary to reserve the thickness nor necessary to perform secondary processing of the cylindrical casing 1 to reduce the thickness of the cylindrical casing 1, at the same time reducing the amount of raw materials used and the difficulty of the Production is reduced while manufacturing costs are reduced.

Furthermore, the limiting ribs 21 and the through groove 11 have a transition fit or a press fit.

From the above explanation, it can be seen that when only one end of the inner liner 2 is provided with a convex lip 22, the limiting ribs 21 and the through groove 11 have an interference fit to improve the connection tightness between the cylindrical housing 1 and the inner liner 2 When only one end of the cylindrical housing 1 is limited by the convex lip 22, since the limiting ribs 21 and the through groove 1 have an interference fit, the cylindrical housing 1 and the inner liner 2 can also maintain a relatively stable connection to prevent the occurrence of wobbling to avoid; If the two ends of the inner liner 2 are each provided with a convex lip 22, the limiting ribs 21 and the through groove 11 can have a transition fit to facilitate assembly.

Furthermore, the limiting rib 21 has a first guide bevel 211 arranged symmetrically along the axial direction of the inner liner 2 and gradually protruding outwardly along the water inlet end to the water outlet end of the inner liner 2.

From the above explanation, it can be seen that with the arrangement of the first guide bevel 211, a guiding function in assembling the inner liner 2 and the cylindrical housing 1 is achieved to improve the assembly efficiency.

Furthermore, the limiting rib 21 has a second guide bevel 212 arranged symmetrically along the axial direction of the inner liner 2, the second guide bevel 212 and the first guide bevel 211 being arranged symmetrically along the radial direction of the inner liner 2, and the second guide bevel 212 along the water outlet end to the water inlet end of the inner liner 2 gradually protrudes outward.

From the above explanation, it can be seen that with the arrangement of the second guide bevel 212, a guiding function in assembling the inner liner 2 and the cylindrical housing 1 is achieved to improve the assembly efficiency.

Further, the first guide bevel 211 and the second guide bevel 212 are in a smooth transitional connection through a connecting surface 213, wherein the connecting surface 213 presses against the inner wall of the through groove 11 in the circumferential direction.

From the above explanation, it can be seen that with the arrangement of the first guide bevel 211 and the second guide bevel 212, the distance between the two ends of the limiting rib 21 is smaller than the width of the through groove 11, therefore, a connecting surface 213 is arranged to ensure a close connection between the limiting rib 21 and the through groove 11, which guarantees the stable connection between the inner lining 2 and the cylindrical housing 1.

Furthermore, the convex lip 22 is an annular convex lip 22.

From the above explanation, it can be seen that by using the convex lip 22, the axial force-bearing area of the cylindrical housing 1 is increased to improve the connection stability between the cylindrical housing 1 and the inner liner 2.

Further, the convex lip 22 includes at least two boundary bodies which are uniformly distributed and arranged on the outer wall of the inner liner 2 in the circumferential direction.

From the above explanation, it can be seen that a plurality of limiting bodies are arranged to ensure that the cylindrical housing 1 stably supports the force in the axial direction.

Furthermore, the water inlet end and the water outlet end of the inner liner 2 are each provided with a convex lip 22.

From the above explanation, it can be seen that the two axial ends of the inner liner 2 are each provided with a convex lip 22 to limit the cylindrical housing 1 in two directions, which ensures that the jet regulator before connecting to the corresponding water outlet device maintains structural integrity to prevent the cylindrical housing 1 from separating from the interior of the inner liner 2 during transport or assembly of the product.

Furthermore, the inner lining 2 comprises a water inlet body 23 and a water outlet body 24 arranged coaxially with the water inlet body 23, the water inlet body 23 and the water outlet body 24 being detachably connected, and the outer walls of the water inlet outlet body 23 and the water outlet body 24 are each provided with a convex lip 22.

From the above explanation, it can be seen that the arrangement of the water outlet body 24 and the water inlet body 23 is to realize a separate assembly to ensure quick assembly of the jet regulator, further it can be ensured that the two ends of a complete jet regulator each have the cylindrical housing 1 limit.

Further, a gap a is provided between at least one convex lip 22 and an end surface of the cylindrical housing 1 in the axial direction.

From the above explanation, it can be seen that with the arrangement of the gap a, an avoidance space is provided between the contact surfaces of the cylindrical housing 1 and the water inlet body 23 to the water outlet device when the housing 1 drives the water outlet body 24 to rotate relative to the water outlet device the smoothness of rotation is ensured in order to avoid that, during rotation, clogging occurs between the housing 1 and the mounting surface of the water outlet device and thus the rotation is impossible or the rotation is blocked.
