Examples

With reference to fig. 1 to 5, the present embodiment provides a hidden water outlet structure, including: a shell 1 and a water outlet joint 2 which is telescopically nested in the shell 1. One side of the shell 1 is provided with a water inlet channel 3, and the water outlet joint 2 is provided with a water passing channel 6 which is provided with a water inlet 4 and a water outlet 5. The water outlet joint 2 can move to a water supply state that the water outlet 5 is exposed outside the shell 1 under the action of the water pressure of the water entering forced into the water inlet channel 3, and the water inlet 4 is communicated with the water inlet channel 3. After water inlet of the water inlet channel 3 is cancelled, the water outlet joint 2 can be elastically reset to the initial state, and the water outlet 5 is hidden in the shell 1.

In the embodiment, the water outlet joint 2 of the hidden water outlet structure can hide the water outlet 5 in the shell 1 when not in use, so that the whole hidden water outlet structure is simpler and more attractive. And only after water is fed, the water outlet connector 2 elastically nested in the shell 1 is pushed to the outside by the pressure of water flow until the water outlet 5 is exposed outside, so that water is fed to a user side. It need not auxiliary structure such as actuating mechanism and directly drives the joint, has greatly made things convenient for the mode of going out water, and the structure is more simple and easy, and manufacturing and maintenance cost are lower. And adopt telescopic water outlet structure, can withdraw delivery port 5 when using, accomodate in casing 1, be difficult for being infected with dust, dirt. Only when in use is pushed out to be exposed outside through water pressure, the water inlet channel 3 can be communicated with the water inlet 4, and water flow is supplied to the water channel 6 and flows out along the water outlet 5.

It should be noted that, when not in use, no water flows into the water inlet channel 3, and at this time, the water outlet connector 2 is not under the action of water pressure and is always in an initial state, so that the water outlet 5 is hidden in the housing 1. When the water supply device is used, when the pressure of water flow supplied by the water inlet channel 3 is greater than the elastic force borne by the water outlet connector 2, the water outlet connector 2 is driven to move until the water outlet 5 of the water outlet connector 2 is exposed outside the shell, the water inlet 4 is communicated with the water inlet channel 3, and at the moment, the water pressure is not increased any more, so that the water outlet connector 2 is positioned at a dynamic balance position and is in a water supply state.

In one embodiment, the housing 1 is provided with a movable cavity 7, and the movable cavity 7 is communicated with the water inlet channel 3. The water outlet joint 2 is slidably arranged on a guide piece 8 arranged in the movable cavity 7 in a penetrating way, an elastic piece 9 is arranged between the guide piece 8 and the water outlet joint 2, and the elastic piece 9 can drive the water outlet joint 2 to move towards one side of the water inlet channel 3 at the initial position, so that the water outlet joint 2 is always in the initial state when not pushed by water pressure. Therefore, under the elastic force abutting of the elastic piece 9, the water outlet connector 2 is embedded in the shell 1 until the water pressure of the water inlet channel 3 acts on the water outlet connector 2, and after the water pressure value is larger than the elastic force value, the water outlet connector 2 can be pushed to move through water flow.

It should be mentioned that the guide 8 serves as a guide for the telescopic movement. The guide member 8 is constructed as a hollow gland structure which is fixedly arranged in the movable chamber 7 and is approximately located at the middle of the chamber. An O-shaped ring is sleeved between the gland structure and the wall of the movable cavity 7, and the gland structure and the movable sleeve are matched through a sealing gasket between the water outlet joints 2 arranged in the hollow part of the gland structure and the movable sleeve, so that the sealing performance of the water outlet structure is ensured.

Referring to fig. 2 and 3, in one embodiment, the water outlet connector 2 includes a body 10, a head 11 and a tail 12. The body 10 is transversely arranged in the movable cavity 7. The head part 11 is arranged at the right side of the body 10, the water outlet 5 is arranged at the head part 11 side and communicated with the water inlet 4 through the water passing channel 6, the tail part 12 is arranged at the left side of the body 10, and the water inlet 4 is arranged at the side surface of the tail part 12. The tail part 12 is configured to be nested in the movable cavity 7 in a piston sliding mode, and when the water outlet joint 2 is switched to a water supply state, the water inlet 4 configured on the tail part 12 can be communicated with the water inlet channel 3 through a gap between the tail part 12 and the cavity wall of the movable cavity 7, and the water passing channel 6 penetrates through the body 10 and is connected with the water inlet 4 on the side of the tail part 12 and the water outlet 5 on the side of the head part 11.

In the above embodiment, the water inlet 4 is disposed on one side of the tail portion 12, such as the upper side or the lower side, so that the water facing side of the left end surface of the tail portion 12 can be straight and block water flow, and the water flow entering the water inlet 4 through the space between the periphery of the tail portion 12 and the wall of the movable chamber 7 is reduced as much as possible. Until the outlet connector 2 is pushed to its water supply state, there is now a larger water flow gap between the edge of the tail 12 and the wall of the chamber where it is located, to allow water flow from the inlet channel 3 to the inlet 4 via the gap. And at the moment, because the water passing gap realizes the conduction of water flow, the water pressure on the water facing side is reduced and quickly tends to be stable, and the water outlet position of the water inlet 4 is ensured not to be influenced by the water pressure.

In particular, the housing 1 is a hollow tubular body, and the water outlet joint 2 is an irregular cylindrical body and is accommodated in the hollow housing 1. It will be appreciated that the hydraulic push mode of motion, typically used in the mouthwash structure of a faucet, is greatly satisfied by the nesting of the hollow tubular and cylindrical bodies to accommodate piston-type push squeezing. In other embodiments, the water outlet joint 2 may also be in the shape of a prism, a cone, etc., and is suitable for use in scenes such as shower spraying, etc.

In one embodiment, the elastic member 9 is disposed outside the body 10, and has one end disposed on the guiding member 8 and the other end disposed on the tail 12. The water outlet connector 2 is nested in the guide 8 through the body 10, and is tightly fitted in the housing 1 through the elastic member 9 sleeved on the body 10 between the guide 8 and the tail 12. When not in use, the elastic element 9 is in a compressed state, thereby ensuring that the elastic element 9 can drive the water outlet connector 2 to be elastically nested in the shell 1. Particularly, the tail part 12 is nested at one end of the body 10 and combined to form a T shape, so that a clamping space for accommodating the elastic part 9 is formed between the tail part 12 and the guide part 8, and the elastic part 9 is sleeved outside the body 10 and compressed in the clamping space.

It should be noted that the elastic force provided by the elastic member 9 to the water outlet 2 is defined as F, and the water pressure provided by the water flow to the water outlet 2 is defined as F. When the water outlet joint 2 is used, the water pressure F is gradually increased until the water pressure F is larger than the initial elastic force F, the water outlet joint 2 is pushed to move, and accordingly the elastic force F is gradually increased under the extrusion action until the elastic force F and the water pressure F tend to be stable and approximately equivalent when the water outlet joint 2 is in a water supply state. The principle is as follows: the purposes that the water outlet 5 can extend out of water or retract and store are achieved by utilizing the interaction of water pressure and elasticity. As can be seen from the formula F — PS, the flow pressure F received by the water outlet joint 2 is in a direct proportion relationship with the flow water pressure P and the area S of the water facing side of the tail 12. The magnitude of the water flow pressure F increases with the increase in the water pressure P and the area S. From the equation f, KX, it can be seen that the elastic force f is in direct proportion to the elastic coefficient K and the compression amount X. The elastic coefficient K is unchanged, and the elastic force is increased along with the increase of the compression amount X. In addition, the movement resistance of the water joint 2 in addition to the elastic force f during expansion and contraction needs to be considered. The water pressure F also needs to be compared to the sum of the spring force F and other resistance forces.

In one embodiment, a flow restrictor 13 is preferably disposed at the junction of the tail 12 and the body 10, and the flow restrictor 13 is received in the water passage 6. Wherein, in order to reduce the flow of the water outlet 5, the flow restrictor 13 is arranged in the water passage 6, so as to realize the purpose of outlet water flow restriction. In addition, the tail part 12 is connected with the body 10 in a screw mode, and after the tail part is assembled, the water passing channel 6 in the body 10 is in butt joint conduction with the water inlet 4 of the tail part 12.

In one embodiment, in order to enable the outlet connector 2 to be in a water supply state, the tail part 12 and the movable cavity 7 can allow water to enter efficiently. Specifically, the movable chamber 7 includes a bearing region 14 smoothly abutting against the water inlet channel 3 and a pressure relief region 15 extending outward from the bearing region 14, wherein the pressure relief region 15 is connected to the bearing region 14 and makes the movable chamber 7 form a horn-shaped opening (as shown in fig. 3). Moreover, the tail part 12 is arranged in a shape similar to the bearing area 14, and the tail part 12 can be accommodated in the bearing area 14 to block the water inlet of the water inlet channel 3 and accommodated in the pressure relief area 15 to be in clearance fit with the cavity wall so as to conduct the water inlet. Therefore, the tail part 12 of the water outlet joint 2 is matched with the cavity wall of the pressure bearing area of the movable cavity 7 by a small clearance at the water facing side and the edge side of the tail part 12, thereby reducing the leakage of water pressure as much as possible and fully bearing the pressure of water flow. Until the tail part 12 of the water outlet joint 2 is pushed to move to the pressure relief area 15 of the movable cavity 7, the clearance matched between the edge side of the tail part 12 and the cavity wall of the pressure relief area 15 is gradually increased, water flow rapidly circulates to the water inlet 4 from the gradually-changed clearance, the water pressure born by the water facing side is gradually reduced at the moment until the water pressure and the elastic force are balanced, and then the water outlet joint 2 is stably placed in a water supply state.

Referring to fig. 1, 2 and 3, in one embodiment, the head 11 is sleeved on the end of the body 10 and can be accommodated in the housing 1. The water outlet 5 disposed on the head 11 side is disposed to be substantially inclined upward so as to be shielded by the wall of the movable chamber 7 when the water outlet joint 2 is in the initial state. Such a configuration mode is suitable for a supply mode of mouthwash outlet water on one hand, can effectively solve the sanitary problem caused by the fact that the water outlet 5 is exposed outside, enables the whole body to be simpler and more attractive, and is particularly suitable for a mouthwash faucet. On the other hand, in the water outlet joint 2 in the initial state, the water outlet 5 of the head 11 is shielded and blocked in the cavity wall in the housing 1, so that even if water flows into the water channel 6 from the water inlet 4 (a small amount of water enters from the gap of the bearing area 14), the water outlet 5 does not leak water, and the normal and stable internal water pressure is maintained.

In addition, a step portion 16 is formed on the outer side of the cavity wall of the movable cavity 7, and the step portion 16 can limit the head portion 11 from moving continuously to the left side under the elastic force, and make the end surface of the head portion 11 approximately flush with one side of the housing 1, so as to meet the requirement of aesthetic feeling. And the head 11 is in sliding fit with the wall of the movable cavity 7 and is tightly matched through a guide rail structure. The guiding structure can be a rib 17 arranged on one side and a sliding groove 18 arranged on the other side, and the guiding limit of the rib 17 in the sliding groove 18 only allows the movement along the opening direction of the sliding groove 18, so that the stability of the telescopic movement of the water outlet joint 2 is improved, and the installation, the disassembly and the maintenance of the head 11 are facilitated.

Referring to fig. 4 and 5, in another embodiment, the head 11 is configured as a universal water nozzle 19 movably hinged at the end of the body 10, and the universal water nozzle 19 is configured with the water outlet 5 approximately flush with the water passage 6. The universal water nozzle 19 is arranged on the body 10 in a ball-hinged mode, so that after the water outlet 5 is moved out to the outside, the water outlet angle of the head 11 can be adjusted randomly according to needs, and the universal water nozzle is suitable for use scenes of multi-directional water supply. The universal water nozzle 19 comprises a bubbler shell, a bubbler, a sealing gasket and the like so as to provide bubbling type water outlet.
