Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, and particularly to a water outlet device. Background Art

[0002] Currently, in order to change the water outlet mode of a faucet, a water outlet device is usually added under the faucet to control or adjust the water output and water outlet state of the faucet.

[0003] In order to make the outer diameter of the water outlet device consistent with that of the faucet, the applicant has applied for the following patent:

[0004] A water outlet control device (authorized announcement number CN104874506B), which discloses including a water distribution body and a water guiding body. The water distribution body includes a through-flow guiding hole; the water guiding body includes a first water inlet, a second water inlet, a first water outlet channel and a second water outlet channel. The upper spaces of the first water inlet and the second water inlet are communicated. The first water inlet is communicated with the first water outlet channel and the second water outlet channel. The second water inlet is communicated with the first water outlet channel. The water outlet of the first water outlet channel is arranged around the water outlet of the second water outlet channel; the water distribution body is rotatably connected with the water guiding body. The guiding hole makes the guiding hole communicate with the first water inlet or the second water inlet respectively with the relative rotation of the water distribution body and the water guiding body. An upper space is formed between the water outlet end of the guiding hole and the first water inlet and the second water inlet.

[0005] In the above patent, through the planar rotation between the water distribution body and the water guiding body, the guiding hole is switched between the first water inlet and the second water inlet, and the first water outlet channel and the second water outlet channel of the water guiding body can respectively form a kind of functional water. Therefore, the water outlet control device in the above patent can realize the switching of two kinds of functional water.

[0006] Although the water outlet control device formed by the above patent is small in volume, it can only realize the water outlet of two kinds of functional water and cannot meet the more needs of users.

[0007] And currently on the market, there are devices that can realize multiple-function water outlet, such as a shower head. Existing shower heads usually have more than three different water outlet modes, but existing shower heads all switch multiple water channels by rotating planar parts. And in the actual R & D process, if the volume of the shower head is to be reduced and applied to a faucet, the minimum outer diameter can only reach 40 mm, which cannot match the size of the faucet. Therefore, it is extremely challenging to realize the switching of multiple functional water in a limited space. Summary of the Invention

[0008] The technical problem to be solved by the present invention is: to provide a multi-functional water outlet device to solve the problem of few water outlet functions of the existing water outlet device.

[0009] In order to solve the above technical problem, the technical solution adopted by the present invention is:

[0010] A multi-functional water outlet device, comprising a first cavity, a second cavity and a flow splitting mechanism;

[0011] The first cavity includes a water inlet channel and a first water outlet channel;

[0012] The flow splitting mechanism includes a second water outlet channel;

[0013] The flow splitting mechanism is arranged through the axis of the first cavity;

[0014] During the movement of the flow splitting mechanism relative to the first cavity, the water inlet channel is communicated with at least one of the first water outlet channel and the second water outlet channel;

[0015] When the water inlet channel is communicated with the first water outlet channel, secondary flow splitting is performed through the second cavity.

[0016] The beneficial effects of the present invention are as follows: The present invention is provided with a flow splitting mechanism and a first cavity, which are used for performing the first water splitting by the flow splitting mechanism and the first cavity during the movement of the second cavity, and performing the second water splitting through the second cavity, so as to realize the water outlet of three kinds of functional water. The setting of the flow splitting mechanism increases the second water outlet channel in a limited space. Compared with the prior art, one more kind of functional water is added, and the overall volume of the water outlet device is not increased. When the water inlet channel is communicated with the second water outlet channel, the first kind of functional water can be formed; when the water inlet channel is communicated with the second water outlet channel, the water flow performs secondary water splitting through the second cavity to form the second kind of functional water and the third kind of functional water. The three kinds of functional water are applicable to different application scenarios, so that a faucet or other sanitary ware products can all become multi-functional water outlet devices to meet the daily needs of users. Compared with the prior art, the structure of the present invention is simple, occupies a small space, and on the basis of not increasing the occupied space, the water outlet of one more kind of functional water is added, realizing the switching between multiple water outlet modes. The present invention forms a difference from the prior art and has greater commercial value and practical value. Description of the Drawings

[0059] To describe in detail the technical content, achieved purposes and effects of the present invention, the following is described in conjunction with the implementation manners and accompanied by the drawings.

[0060] Please refer to Figures 1 - 33 , a multifunctional water outlet device, including a first cavity, a second cavity and a diverting mechanism;

[0061] The first cavity includes a water inlet channel and a first water outlet channel;

[0062] The diverting mechanism includes a second water outlet channel;

[0063] The diverting mechanism is arranged through the axis of the first cavity;

[0064] During the movement of the flow splitting mechanism relative to the first cavity, the water inlet channel is in communication with at least one of the first water outlet channel and the second water outlet channel;

[0065] When the water inlet channel is in communication with the first water outlet channel, secondary flow splitting is carried out through the second cavity.

[0066] The working principle of the present invention is as follows:

[0067] During the movement of the flow splitting mechanism relative to the first cavity, when the water inlet channel is in communication with the second water outlet channel, the first type of functional water is formed;

[0068] When the water inlet channel is in communication with the first water outlet channel, the water flow is secondarily split through the second cavity to form the second type of functional water or the third type of functional water.

[0069] As can be seen from the above description, the beneficial effects of the present invention are as follows: The present invention is provided with a flow splitting mechanism and a first cavity, which are used for the first water splitting by the flow splitting mechanism and the first cavity during the movement of the second cavity, and the second water splitting is carried out through the second cavity, realizing the outlet of three types of functional water. The setting of the flow splitting mechanism increases the second water outlet channel within a limited space. Compared with the prior art, one more type of functional water is added, and the overall volume of the water outlet device is not increased. When the water inlet channel is in communication with the second water outlet channel, the first type of functional water can be formed; when the water inlet channel is in communication with the second water outlet channel, the water flow is secondarily split through the second cavity to form the second type of functional water and the third type of functional water. The three types of functional water are applicable to different application scenarios, enabling faucets or other sanitary products to become multi-functional water outlet devices to meet the daily needs of users. Compared with the prior art, the present invention has a simple structure and occupies a small space. Without increasing the occupied space, one more type of functional water outlet is added, realizing the switching between multiple water outlet modes. The present invention forms a differentiation from the prior art and has greater commercial value and practical value.

[0070] Further, the flow splitting mechanism and the second cavity can move relative to the first cavity. During the movement of the flow splitting mechanism and the second cavity relative to the first cavity, the water inlet channel is in communication with the first water outlet channel and the second water outlet channel, or is simultaneously in communication with the first water outlet channel and the second water outlet channel.

[0071] As can be seen from the above description, when the water inlet channel is simultaneously in communication with the first water outlet channel and the second water outlet channel, the first water outlet channel is secondarily split through the second water inlet cavity, and at this time, another form of functional water can be formed, enriching the water outlet modes of the faucet.

[0072] Further, the first cavity includes a water outlet hole, and the second cavity includes a third water outlet channel and a fourth water outlet channel;

[0073] The first water outlet channel is communicated with the third water outlet channel or the fourth water outlet channel through the water outlet hole.

[0074] As can be seen from the above description, the first cavity includes a water outlet hole, which is used to form a communication relationship between the first water outlet channel and the third water outlet channel or the fourth water outlet channel, so as to perform secondary water diversion and form two other types of functional water, enriching the functions of the water outlet device.

[0075] Furthermore, the water outlet hole is an oblong hole.

[0076] As can be seen from the above description, the water outlet hole is an oblong hole. Compared with a round hole, the flow area of the water flow is compressed, which plays a guiding role for the water flow, avoiding the situation that when the water flow flows out of the water outlet hole, it can only flow into the third water outlet channel or the fourth water outlet channel, rather than flowing into both channels at the same time, resulting in a poor water outlet state of the functional water.

[0077] Furthermore, the water inlet assembly includes an upper water inlet ring, a lower water inlet ring, a first gasket, a second gasket and a buckle;

[0078] The first gasket is embedded in the top of the lower water inlet ring;

[0079] The second gasket is embedded in the lower water inlet ring and is located below the buckle;

[0080] The upper water inlet ring is embedded in the top inside the lower water inlet ring.

[0081] As can be seen from the above description, the second gasket is provided to minimize or block the water flow passing between the flow splitting mechanism and the water inlet assembly, so as to ensure sufficient water flow flowing into the third water outlet channel and the fourth water outlet channel through the water outlet hole; and the buckle is used to press the second gasket to prevent the second gasket from floating up and blocking the water outlet of the lower water inlet ring, avoiding the failure of secondary water diversion and resulting in the water flow only being able to flow out from the second water outlet channel.

[0082] Furthermore, an installation hole is provided in the second cavity;

[0083] A step is provided on the installation hole;

[0084] The flow splitting mechanism passes through the installation hole and is rotatably pressed against the step.

[0085] Furthermore, the step includes a first step surface and a second step surface;

[0086] The first step surface and the second step surface are connected by an inclined surface in a transitional manner.

[0087] Further, a protrusion that can move up and down along the steps is provided outside one end of the flow splitting mechanism located in the second cavity.

[0088] As can be seen from the above description, an installation hole is opened in the second cavity for the flow splitting mechanism to pass through the installation hole to provide support for the flow splitting mechanism, enabling the flow splitting mechanism to longitudinally change its position under the direct action of the second cavity, making the transmission between the flow splitting mechanism and the second cavity more reliable, with better stability, and the positioning of the flow splitting mechanism more accurate. At the same time, the number of components and the occupied space are reduced.

[0089] Further, there is a pressure cavity between one side of the flow splitting mechanism away from the second cavity and the first cavity.

[0090] As can be seen from the above description, a pressure cavity is provided between the flow splitting mechanism and the first cavity to ensure sufficient water inlet space is reserved between the flow splitting mechanism and the pressure cavity. When the second cavity undergoes a position change and the supporting force at the bottom of the flow splitting mechanism is removed, the water pressure in the pressure cavity can form sufficient driving force on the flow splitting mechanism to drive the flow splitting mechanism to move downward by itself, realizing smooth switching between different functional waters.

[0091] Further, a blocking platform for blocking the first water outlet channel is provided at one end of the flow splitting mechanism located in the first cavity.

[0092] As can be seen from the above description, by setting the blocking platform, when the flow splitting mechanism is at the bottom of the moving space in the first cavity, the first water outlet channel can be blocked to meet the water outlet conditions of the first functional water.

[0093] Further, the flow splitting mechanism includes a flow splitter and a reset member;

[0094] One end of the reset member is installed in the flow splitter, and the other end abuts against one side of the first cavity.

[0095] As can be seen from the above description, the flow splitter and the reset member are provided to push the flow splitter to change its spatial position in the first cavity, realizing rotational switching of multiple functional waters.

[0096] Further, the first cavity includes a water inlet assembly and a water outlet assembly;

[0097] The water inlet assembly is installed in the water outlet assembly, and the flow splitting mechanism is installed in the water inlet assembly and sequentially passes through the water inlet assembly, the water outlet assembly, and the second cavity.

[0098] As can be seen from the above description, the flow splitting mechanism passes through the water inlet assembly, the water outlet assembly, and the second cavity, enabling the flow splitting mechanism to move up and down at the axis of the water inlet assembly, the water outlet assembly, and the second cavity. By means of spatial movement, the connection relationship between the first water outlet channel and the second water outlet channel and the water inlet channel is changed.

[0099] The water outlet device of the present invention can be applied to scenarios such as kitchen faucets, bathroom faucets, extraction showers, or bidets.

[0103] Embodiment 2

[0104] This embodiment is applicable to a kitchen faucet with an external thread 126 or a bathroom faucet with an external thread 126.

[0105] The difference between this embodiment and Embodiment 1 lies in defining the specific structure of the water outlet device.

[0106] Refer to Figures 1 - 9 , the first cavity 1 includes a plurality of uniformly distributed water outlet holes 1211, the second cavity 2 includes a fourth water outlet channel 40 and a third water outlet channel 50; the first water outlet channel 20 communicates with the second cavity 2 through the water outlet holes 1211, and when the second cavity 2 moves relative to the first cavity 1, the first water outlet channel 20 communicates with the fourth water outlet channel 40 or the third water outlet channel 50 through the water outlet holes 1211 for secondary water distribution.

[0107] Refer to Figure 9 , an installation hole 21 is further formed in the second cavity 2; a step 211 is arranged on the installation hole 21; the flow splitting mechanism 3 is arranged through the installation hole 21 and rotatably abuts against the step 211.

[0108] Preferably, two steps 211 are symmetrically arranged on the installation hole 21. The step 211 includes a first step surface 2111 and a second step surface 2112, and the first step surface 2111 and the second step surface 2112 are sequentially arranged in a surrounding manner from bottom to top. The first step surface 2111 and the second step surface 2112, the second step surface 2112 and another first step surface 2111, and another second step surface 2112 and the first step surface 2111 are all smoothly connected through a transition inclined surface;

[0109] Refer to Figure 5 , a protrusion 31 is provided outside one end of the flow dividing mechanism 3 located in the second cavity 2, and the protrusion 31 can move up and down along the step 211; the upper end of the protrusion 31 is inserted into the first cavity 1.

[0110] Preferably, there are two protrusions 31, and the two protrusions 31 are symmetrically arranged on the outer wall of the flow dividing mechanism 3;

[0111] Refer to Figure 3 and Figure 5 , a blocking platform 32 for blocking the third water outlet channel 50 and the fourth water outlet channel 40 is provided at one end of the flow dividing mechanism 3 located in the first cavity 1.

[0112] Refer to Figure 5 , the flow dividing mechanism 3 includes a flow dividing body 33 and a reset member 34. One end of the reset member 34 is installed in the flow dividing body 33, and the other end abuts against one side of the first cavity 1. Preferably, the protrusion 31, the blocking platform 32 and the flow dividing body 33 are integrally formed; preferably, the reset member 34 is a compression spring.

[0113] Refer to Figure 5 , a first annular boss 35 is further installed on the top of the blocking platform 32. The blocking platform 32 is installed outside the first annular boss 35. The distance between the blocking platform 32 and the first cavity 1 is greater than the distance between the first annular boss 35 and the first cavity 1, that is, there is a pressure cavity 70 between the blocking platform 32 and the first cavity 1. The area of the first annular boss 35 facing the first cavity 1 is smaller than the area of the blocking platform 32 facing the first cavity 1, and the planar area of the blocking platform 32 facing the first cavity 1 is smaller than the planar area of the blocking platform 32 facing the second cavity 2 (excluding the inclined plane part), so that the water pressure between the first cavity 1 and the blocking platform 32 plus the pushing force of the reset member 34 can be greater than the water pressure below the blocking platform 32 to push the flow dividing body 33 to move downward;

[0114] Refer to Figure 5 , a functional member 36 is installed in the flow dividing body 33. One end of the reset member 34 abuts against the functional member 36, and the other end abuts against one side of the first cavity 1.

[0115] Specifically, refer to Figure 5 , a first annular step 331 and a second annular step 332 are provided in the flow dividing body 33. The first annular step 331 and the second annular step 332 are arranged in order from top to bottom. The diameter of the first annular step 331 is larger than that of the second annular step 332. The lower end of the functional member 36 is pressed against the first annular step 331. The water outlet of the flow dividing body 33 is circular and can spray columnar spray water;

[0116] Refer to Figure 1 and Figure 3, the first cavity 1 includes a water inlet assembly 11 and a water outlet assembly 12. One end of the flow splitting mechanism 3 is movably installed in the water inlet assembly 11, and the other end is movably arranged through the water outlet assembly 12. The water inlet assembly 11 is installed in the water outlet assembly 12, and the flow splitting mechanism 3 is installed in the water inlet assembly 11 and sequentially passes through the water inlet assembly 11, the water outlet assembly 12 and the second cavity 2. The first water outlet channel 20 is located between the water inlet assembly 11 and the water outlet assembly 12, and the first water outlet channel 20 is used to connect the water inlet channel 10 and the fourth water outlet channel 40 or to connect the water inlet channel 10 and the third water outlet channel 50; the second cavity 2 and the water outlet assembly 12 are snap-connected.

[0117] Specifically, the water outlet assembly 12 includes a water outlet body 121. An internal thread 122 for connecting with a faucet is arranged at the top of the water outlet body 121. An accommodating cavity 123 for installing a gear component 124 is concavely arranged on the outer wall of the water outlet body 121. The water outlet body 121 is limited by the accommodating cavity 123 with respect to the water inlet assembly 11. The gear component 124 in the accommodating cavity 123 includes a spring and a roller. The spring is horizontally installed in the accommodating cavity 123 and presses against one side of the roller. The roller is slidably pressed against different limiting slots 1212 on the inner wall of the top of the water outlet body 121 under the push of the spring. The position of each limiting slot 1212 corresponds to a water outlet state, so as to feel the gear change during the rotation of the second cavity 2 relative to the first cavity 1; a water outlet hole 1211 is opened on the side of the water outlet body 121 facing the second cavity 2.

[0118] Referring to Figure 7 , Figure 8 and Figure 10 , it further includes a housing 4. The housing 4 is installed outside the water outlet assembly 12 and the second cavity 2. There is an air intake gap 60 between the water outlet assembly 12 and the housing 4. A plurality of uniformly distributed bumps 125 are arranged at both the upper and lower ends of the outer wall of the water outlet assembly 12, so as to leave gaps between the water outlet assembly 12 and the housing 4 and between the water outlet assembly 12 and the second cavity 2 to ensure the smoothness of the air intake gap 60; the air intake gap 60 is communicated with the third water outlet channel 50. A metal gasket 5 for blocking the upward flow of water and increasing the air intake pressure is installed between the second cavity 2 and the water outlet assembly 12. The setting of the metal gasket 5 can also make the relative friction smaller when the second cavity 2 contacts during the rotation process with the water outlet body 121, making the rotation smoother.

[0119] Specifically, the second cavity 2 is rotatably clamped to the water outlet body 121; the second cavity 2 is connected to the housing 4 by a snap connection, that is, the male snap 201 on the outer surface of the second cavity 2 is snapped into the female snap 401 on the inner wall of the housing 4. The inner wall of the housing 4 is provided with an upper limit platform 41 and a lower limit platform 42. The female snap 401 is opened on the side wall of the upper limit platform 41, and a limit groove 2011 matching the lower limit platform 42 is opened on the male snap 201 on the outside of the second cavity 2. The male snap 201 is inserted into the female snap 401 and continuously moved downward until the lower limit platform 42 is embedded in the limit groove 2011, and the upper end of the male snap 201 is limited in the female snap 401, so that the second cavity 2 can rotate with the rotation of the housing 4;
