Description

Technical Field

[0001] The invention relates to the field of bathrooms, in particular to a water outlet device. Background Art

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

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

[0004] A water outlet control device (authorization announcement number CN104874506B) is disclosed, comprising a water diversion body and a water guide body, the water diversion body comprising a through diversion hole; the water guide body comprising 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 connected, the first water inlet is connected to the first water outlet channel and the second water outlet channel, the second water inlet is connected to 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 diversion body is rotatably connected to the water guide body, the diversion hole is connected to the first water inlet or the second water inlet respectively with the relative rotation of the water diversion body and the water guide body, and an upper space is formed between the water outlet end of the diversion hole and the first water inlet and the second water inlet.

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

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

[0007] Currently, there are devices on the market that can achieve multi-functional water output, such as showers. Existing showers usually have more than three different water output methods, but existing showers all use plane rotating parts to switch multiple water channels. In the actual research and development process, if the size of the shower is to be reduced and applied to the faucet, the minimum outer diameter can only reach 40mm, which cannot match the size of the faucet. Therefore, it is extremely challenging to achieve 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 water outlet device to solve the problem that the existing water outlet device has few water outlet functions.

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

[0010] A water outlet device comprises a water inlet mechanism, a flow diversion mechanism and a flow guide mechanism rotatably connected to the water inlet mechanism;

[0011] The diversion mechanism is installed in the water inlet mechanism and passes through the axis of the flow guide mechanism;

[0012] The water inlet mechanism comprises a water inlet channel;

[0013] The diversion mechanism includes a first water outlet channel;

[0014] The flow guiding mechanism comprises a second water outlet channel and a third water outlet channel;

[0015] When the flow guiding mechanism moves relative to the flow dividing mechanism, the water inlet channel is communicated with the first water outlet channel, the second water outlet channel or the third water outlet channel.

[0016] The beneficial effects of the present invention are as follows: the present invention is provided with a diverter mechanism for switching different water outlet modes during the activity of the diverter mechanism. At the same time, the diverter mechanism is provided to add a first water outlet channel in a limited space. Compared with the prior art, a functional water is added, and the overall volume of the water outlet device is not increased. When the water inlet channel is connected to the first water outlet channel, a first functional water can be formed; when the water inlet channel is connected to the second water outlet channel, a second functional water can be formed; when the water inlet channel is connected to the third water outlet channel, a third functional water can be formed; the three functional waters are suitable for different application scenarios, so that faucets or other sanitary products can all become multifunctional 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. On the basis of not increasing the occupied space, a functional water outlet is added, and switching between multiple water outlet modes is realized, which is more practical.

[0055] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0056] Please refer to Figure 1-Figure 29 , a water outlet device, comprising a water inlet mechanism, a flow guide mechanism connected to the water inlet mechanism, and a flow diversion mechanism installed in the water inlet mechanism and passing through the flow guide mechanism;

[0057] The water inlet mechanism comprises a water inlet channel;

[0058] The diversion mechanism includes a first water outlet channel;

[0059] The flow guiding mechanism comprises a second water outlet channel and a third water outlet channel;

[0060] When the flow guiding mechanism moves relative to the flow dividing mechanism, the water inlet channel is communicated with the first water outlet channel, the second water outlet channel or the third water outlet channel.

[0061] The working principle of the present invention is:

[0062] The flow diversion mechanism is arranged through the axis of the flow diversion mechanism, thereby increasing the outlet of a functional water without increasing the volume of the water outlet device;

[0063] When the diversion mechanism is located at the bottom of the activity space in the water inlet mechanism, the water inlet channel is connected with the first water outlet channel to form the first functional water;

[0064] When the diversion mechanism is located at the top of the activity 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 functional water or the third functional water.

[0065] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention is provided with a diverter mechanism for switching different water outlet modes during the activity of the diverter mechanism, and the diverter mechanism is provided to increase the first water outlet channel in a limited space. Compared with the prior art, a functional water is added, and the overall volume of the water outlet device is not increased. When the water inlet channel is connected to the first water outlet channel, a first functional water can be formed; when the water inlet channel is connected to the second water outlet channel, a second functional water can be formed; when the water inlet channel is connected to the third water outlet channel, a third functional water can be formed; the three functional waters are suitable for different application scenarios, so that faucets or other bathroom products can all become multifunctional 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. On the basis of not increasing the occupied space, the third functional water outlet is added, and switching between multiple water outlet modes is realized, which is more valuable.

[0066] Furthermore, the flow guiding mechanism and the flow diverting mechanism can move relative to the water inlet mechanism. When the flow guiding mechanism and the flow diverting mechanism move relative to the water inlet mechanism, the water inlet channel is connected with the first water outlet channel, the second water outlet channel or the third water outlet channel.

[0067] From the above description, it can be seen that when the diversion mechanism and the diversion mechanism are simultaneously moving relative to the water inlet mechanism, the water inlet channel is connected with the first water outlet channel, the second water outlet channel or the third water outlet channel, realizing another switching method, which can also realize the switching of three functional water.

[0068] Furthermore, when the flow guiding mechanism moves relative to the water inlet mechanism, the water inlet channel is connected to the first water outlet channel, the second water outlet, or to the first water outlet channel and the third water outlet channel simultaneously.

[0069] From the above description, it can be seen that during the activity of the diversion mechanism relative to the water inlet mechanism, there is a third connection relationship between the water inlet channel and the first water outlet channel, the second water outlet channel and the third water outlet channel, thereby realizing the switching of the three functional water outlet states and enriching the water outlet methods of the faucet.

[0070] Furthermore, the diversion mechanism includes a water outlet hole, and when the guide mechanism rotates relative to the diversion 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.

[0071] As can be seen from the above description, the water outlet hole is provided to perform a second water diversion on the water flow in the water inlet channel during the process of the flow guide mechanism rotating relative to the diversion mechanism. The water flow in the water inlet mechanism is firstly divided through the diversion mechanism, and when the first water outlet channel is closed, the water flow in the water inlet mechanism is connected with the second water outlet channel or the third water outlet channel through the water outlet hole, so as to realize the discharge of the second functional water and the discharge of the third functional water.

[0072] Furthermore, a mounting hole is provided in the flow guide mechanism;

[0073] The mounting hole is provided with a step;

[0074] The diversion mechanism is arranged through the mounting hole and is rotatably pressed against the step.

[0075] Further, the step includes a first step surface and a second step surface;

[0076] The first step surface and the second step surface are connected by an inclined transition.

[0077] Furthermore, a protrusion is provided outside one end of the flow diversion 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.

[0078] It can be seen from the above description that a mounting hole is opened in the guide mechanism, which is used for the diverter mechanism to be set through the mounting hole to provide support for the diverter mechanism; a step including a first step surface and a second step surface is arranged on the mounting hole, which is used for the protrusion to move along the first step surface and the second step surface, so that the diverter mechanism can be changed in position in the water inlet mechanism to realize the switching between different functional waters, wherein the first step surface and the second step surface are connected by an inclined transition, so that the protrusion can move smoothly on the first step surface and the second step surface; and the diverter mechanism can automatically change its position up and down under the direct action of the guide mechanism, so that the transmission between the diverter mechanism and the guide mechanism is more reliable, the stability is better, and the positioning of the diverter mechanism is more accurate, while reducing the number of components and the occupied space.

[0079] Furthermore, the upper end of the protrusion is inserted into the water inlet mechanism.

[0080] From the above description, it can be seen that the protrusion is inserted into the water inlet mechanism, which can maintain a stable relative position relationship between the diverter mechanism and the water inlet mechanism, so that the guide mechanism can rotate relative to the diverter mechanism and the water inlet mechanism, making the transmission more stable and stably switching between different water outlet channels.

[0081] Furthermore, a blocking platform for blocking the second water outlet channel is provided at one end of the diversion mechanism located in the water inlet mechanism.

[0082] It can be seen from the above description that a blocking platform is provided, and when the diversion mechanism is located at the bottom of the activity space of the water inlet mechanism, the second water outlet channel can be blocked to meet the water outlet condition of the first functional water.

[0083] Furthermore, the flow diversion mechanism includes a flow diversion body and a reset member;

[0084] One end of the resetting member is installed in the flow divider, and the other end is pressed against one side of the water inlet mechanism.

[0085] It can be seen from the above description that the splitter body and the reset member are provided to promote the spatial position change of the splitter body in the water inlet mechanism to realize the rotation switching of multiple functional water.

[0086] Furthermore, the flow divider is provided with functional parts;

[0087] One end of the reset member presses against the functional member, and the other end presses against one side of the water inlet mechanism.

[0088] From the above description, it can be seen that functional parts are installed in the flow divider, and the functional parts can be replaced according to actual use, so that when water flows out of the flow divider, a special water flow state, such as spray water, is formed under the action of the functional parts.

[0089] Furthermore, the water inlet mechanism includes a water inlet component and a water outlet component;

[0090] One end of the diversion mechanism is movably installed in the water inlet assembly, and the other end is movably arranged through the water outlet assembly;

[0091] A transition channel for connecting the water inlet channel and the second water outlet channel is formed between the water inlet component and the water outlet component.

[0092] It can be seen from the above description that the formation of the transition channel is used to achieve the communication between the water inlet channel and the second water outlet channel.

[0093] Furthermore, the flow guiding mechanism and the water outlet assembly are snap-fitted and connected.

[0094] It can be seen from the above description that the flow guiding mechanism and the water outlet assembly are snap-fitted and connected so that a stable relative movement positional relationship is formed between the flow guiding mechanism and the water outlet assembly.

[0095] Furthermore, it also includes a housing;

[0096] The shell is installed outside the water outlet assembly and the flow guide mechanism;

[0097] An air intake gap is provided between the water outlet assembly and the housing;

[0098] The air inlet gap is in communication with the second water outlet channel.

[0099] From the above description, it can be seen that an air intake gap is provided between the shell and the water outlet assembly, and the air intake gap is connected to the second water outlet channel. According to the Bernoulli principle and the Venturi effect, the gas will be sucked into the water flow from the air intake gap, so that the gas is mixed with the water in the second water outlet channel to form bubble water or shower water, thereby reducing the impact force generated when the water flow is sprayed onto the skin surface, thereby reducing the discomfort caused by the water flow impact to the user.
