Description

[0001] This divisional application is based on the mother patent of an invention patent with an application date of July 7, 2020, an application number of 2020106466941, and a title of "A water outlet device". Technical Field

[0002] The present invention relates to the sanitary ware field, and in particular to a water outlet device. Background Art

[0003] Currently, 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.

[0004] 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 patents:

[0005] 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, and 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, and an upper space is formed between the water outlet end of the guiding hole and the first water inlet and the second water inlet.

[0006] 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.

[0007] 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.

[0008] And currently on the market, there are devices that can realize multi-functional 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

[0009] The technical problem to be solved by the present invention is: to provide a water outlet device to solve the problem of few water outlet functions of the existing water outlet devices.

[0010] To solve the above technical problem, the technical solution adopted by the present invention is:

[0011] A water outlet device includes a water inlet mechanism, a flow splitting mechanism, and a diversion mechanism rotatably connected to the water inlet mechanism;

[0012] The flow splitting mechanism is installed in the water inlet mechanism and is arranged through the axis of the diversion mechanism;

[0013] The water inlet mechanism includes a water inlet channel;

[0014] The flow splitting mechanism includes a first water outlet channel;

[0015] The diversion mechanism includes a second water outlet channel and a third water outlet channel;

[0016] When the diversion mechanism moves relative to the flow splitting mechanism, the water inlet channel communicates with the first water outlet channel, the second water outlet channel, or the third water outlet channel.

[0017] The beneficial effects of the present invention are as follows: The present invention is provided with a flow splitting mechanism for switching different water outlet modes during the movement of the diversion mechanism. At the same time, the flow splitting mechanism increases the first water outlet channel in a limited space. Compared with the prior art, a kind of functional water is added without increasing the overall volume of the water outlet device. When the water inlet channel communicates with the first water outlet channel, the first kind of functional water can be formed; when the water inlet channel communicates with the second water outlet channel, the second kind of functional water can be formed; when the water inlet channel communicates with the third water outlet channel, the third kind of functional water can be formed; the three kinds 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 structure of the present invention is simple and occupies less space. On the basis of not increasing the occupied space, the water outlet of a kind of functional water is increased, realizing the switching between multiple water outlet modes, and has more practical value.

[0056] To describe the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the implementation modes and with reference to the drawings.

[0057] Please refer to Figures 1 - 29 , a water outlet device, comprising a water inlet mechanism, a flow guiding mechanism connected to the water inlet mechanism, and a flow splitting mechanism installed in the water inlet mechanism and arranged through the flow guiding mechanism;

[0058] The water inlet mechanism includes a water inlet channel;

[0059] The flow splitting mechanism includes a first water outlet channel;

[0060] The flow guiding mechanism includes a second water outlet channel and a third water outlet channel;

[0061] When the flow guiding mechanism moves relative to the flow splitting mechanism, the water inlet channel communicates with the first water outlet channel, the second water outlet channel or the third water outlet channel.

[0062] The working principle of the present invention lies in:

[0063] The flow splitting mechanism is arranged through the axis of the flow guiding mechanism, adding the outlet of a kind of functional water without increasing the volume of the water outlet device.

[0064] When the flow splitting mechanism is located at the bottom of the movable space in the water inlet mechanism, the water inlet channel is communicated with the first water outlet channel to form the first kind of functional water.

[0065] When the flow splitting mechanism is located at the top of the movable space in the water inlet mechanism, the water inlet channel is communicated with the second water outlet channel or the third water outlet channel to form the second kind of functional water or the third kind of functional water.

[0066] 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 for switching different water outlet modes during the movement of the flow guiding mechanism. At the same time, the flow splitting mechanism adds a first water outlet channel within a limited space. Compared with the prior art, a 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 first 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 second kind of functional water can be formed; when the water inlet channel is communicated with the third water outlet channel, the third kind of functional water can be formed. The three kinds 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 structure of the present invention is simple, occupies less space, and on the basis of not increasing the occupied space, the outlet of the third kind of functional water is added, realizing the switching between multiple water outlet modes, and having more use value.

[0067] Further, the flow guiding mechanism and the flow splitting mechanism can move relative to the water inlet mechanism. During the movement of the flow guiding mechanism and the flow splitting mechanism relative to the water inlet mechanism, the water inlet channel is communicated with the first water outlet channel, the second water outlet channel or the third water outlet channel.

[0068] As can be seen from the above description, during the simultaneous movement of the flow guiding mechanism and the flow splitting mechanism relative to the water inlet mechanism, the water inlet channel is communicated with the first water outlet channel, the second water outlet channel or the third water outlet channel, realizing another switching mode, and the switching of the three kinds of functional water can also be realized.

[0069] Further, during the movement of the flow guiding mechanism relative to the water inlet mechanism, the water inlet channel is communicated with the first water outlet channel, the second water outlet or simultaneously communicated with the first water outlet channel and the third water outlet channel.

[0070] As can be seen from the above description, during the movement of the flow guiding mechanism relative to the water inlet mechanism, there is a third kind of communication relationship among the water inlet channel, the first water outlet channel, the second water outlet channel and the third water outlet channel, realizing the switching of the water outlet states of the three kinds of functional water and enriching the water outlet modes of the faucet.

[0071] Furthermore, the flow splitting mechanism includes a water outlet hole. During the rotation of the flow guiding mechanism relative to the flow splitting mechanism, the water inlet channel switches its connection relationship with the second water outlet channel or the third water outlet channel through the water outlet hole.

[0072] As can be seen from the above description, the water outlet hole is provided to perform a second water division on the water flow in the water inlet channel during the rotation of the flow guiding mechanism relative to the flow splitting mechanism. The water flow is first divided by the flow splitting mechanism in the water inlet mechanism. When the first water outlet channel is closed, the water flow in the water inlet mechanism is connected to the second water outlet channel or the third water outlet channel through the water outlet hole, realizing the outlet of the second functional water and the third functional water.

[0073] Furthermore, an installation hole is also formed in the flow guiding mechanism;

[0074] A step is provided on the installation hole;

[0075] The flow splitting mechanism passes through the installation hole and is rotatably pressed against the step.

[0076] Furthermore, the step includes a first step surface and a second step surface;

[0077] The first step surface and the second step surface are transitionally connected by an inclined surface.

[0078] Furthermore, a protrusion is provided on the outer side of one end of the flow splitting mechanism located inside the flow guiding mechanism, and the protrusion moves up and down along the step during the rotation of the flow guiding mechanism.

[0079] As can be seen from the above description, the installation hole is formed in the flow guiding mechanism to enable the flow splitting mechanism to pass through the installation hole and provide support for the flow splitting mechanism. The step including the first step surface and the second step surface is provided on the installation hole to enable the protrusion to move along the first step surface and the second step surface, so that the flow splitting mechanism performs position conversion in the water inlet mechanism to realize the switching between different functional waters. Among them, the first step surface and the second step surface are transitionally connected by an inclined surface, which can realize the smooth movement of the protrusion on the first step surface and the second step surface. And the flow splitting mechanism can automatically change its position up and down under the direct action of the flow guiding mechanism, making the transmission between the flow splitting mechanism and the flow guiding mechanism 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.

[0080] Furthermore, the upper end of the protrusion is inserted into the water inlet mechanism.

[0081] As described above, the protrusion is inserted into the water inlet mechanism, which can keep the relative position relationship between the flow splitting mechanism and the water inlet mechanism stable, enable the diversion mechanism to rotate relative to the flow splitting mechanism and the water inlet mechanism, make the transmission more stable, and stably switch different water outlet channels.

[0082] Further, a blocking platform for blocking the second water outlet channel is provided at one end of the flow splitting mechanism located inside the water inlet mechanism.

[0083] As described above, by providing the blocking platform, when the flow splitting mechanism is at the bottom of the moving space of the water inlet mechanism, the second water outlet channel can be blocked to meet the water outlet conditions of the first type of functional water.

[0084] Further, the flow splitting mechanism includes a flow splitter and a reset member;

[0085] One end of the reset member is installed inside the flow splitter, and the other end abuts against one side of the water inlet mechanism.

[0086] As described above, the flow splitter and the reset member are provided to push the flow splitter to change its spatial position inside the water inlet mechanism, so as to realize the rotational switching of multiple types of functional water.

[0087] Further, a functional member is installed inside the flow splitter;

[0088] One end of the reset member abuts against the functional member, and the other end abuts against one side of the water inlet mechanism.

[0089] As described above, by installing the functional member inside the flow splitter and the functional member can be replaced according to actual use, when the water flows out of the flow splitter, under the action of the functional member, a special water flow state, such as spray water, is formed.

[0090] Further, the water inlet mechanism includes a water inlet assembly and a water outlet assembly;

[0091] One end of the flow splitting mechanism is movably installed inside the water inlet assembly, and the other end is movably arranged through the water outlet assembly;

[0092] A transition flow channel for communicating the water inlet channel and the second water outlet channel is formed between the water inlet assembly and the water outlet assembly.

[0093] As described above, the formation of the transition flow channel is used to realize the communication between the water inlet channel and the second water outlet channel.

[0094] Further, the diversion mechanism and the water outlet assembly are snap-connected.

[0095] As described above, the diversion mechanism and the water outlet assembly are snap-connected so as to form a stable relative movement position relationship between the diversion mechanism and the water outlet assembly.

[0096] Further, it further includes a housing;

[0097] The housing is installed outside the water outlet assembly and the diversion mechanism;

[0098] There is an air intake gap between the water outlet assembly and the housing;

[0099] The air intake gap communicates with the second water outlet channel.

[0100] As can be seen from the above description, an air intake gap is provided between the housing and the water outlet assembly, and the air intake gap communicates with the second water outlet channel. According to Bernoulli's principle and the Venturi effect, gas will be sucked into the water flow from the air intake gap, so that the gas mixes with water in the second water outlet channel to form bubble water or sprinkler water, reducing the impact force generated when the water flow jets onto the skin surface, and further reducing the discomfort caused by the water flow impact to the user.

[0101] The water outlet device of the present invention can be applied to application scenarios such as kitchen faucets, bathroom faucets, extraction showers or bidets.
