Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a drainage structure and a water outlet device. Background Art

[0002] In current shower heads, after the user stops the water supply, water is still left in the hose and handle of the shower head. This residual water is easy to drip through the water outlet of the shower head cover, wetting the user and causing a poor user experience. In particular, existing shower heads often install a filter element at the handle of the shower head. Since the filter element contains functional materials that rely on dissolving in water and continuously releasing to exert their effects, such as vitamin C cream, after the shower water channel is turned off, the water still remaining at the handle continues to soak the filter element, and the functional materials continue to dissolve in the residual water, resulting in a shortened life of the functional materials. At the same time, after the filter element absorbs a large amount of organic matter, it is more likely to become a breeding ground for bacteria and produce secondary pollutants if it is immersed in residual water for a long time. Utility Model Content

[0003] The purpose of the embodiments of the utility model is to provide a drainage structure and a water outlet device with a simple structure and capable of quickly draining residual water in response to the existing technical status.

[0004] In order to achieve the above-mentioned purpose, the embodiment of the utility model adopts the following technical solutions:

[0005] On the one hand, an embodiment of the utility model discloses a drainage structure, including a shell, wherein the shell is provided with a water inlet and a main water outlet, a water path switching section is provided between the water inlet and the main water outlet, a water through hole for connecting the water inlet and the main water outlet is provided inside the water path switching section, and a water outlet is provided on the side wall of the water path switching section, the water outlet is provided on a side of the water through hole close to the main water outlet, a movable water blocking member is rotatably provided between the water through hole and the water outlet, and the movable water blocking member has a first position for blocking the water through hole and a second position for blocking the water outlet.

[0006] In some embodiments, a reset elastic member for driving the movable water retaining member to flip in a direction close to the first position is further provided in the water channel switching section.

[0007] In some embodiments, the movable water-blocking member includes a rotating bracket and a baffle that are interconnected. The rotating bracket is rotatably disposed in the water channel switching section. The rotating axis of the rotating bracket is perpendicular to the water outlet direction of the water hole.

[0008] In some embodiments, the inner wall of the water channel switching section protrudes inward to form a first plane, the water outlet is arranged on the first plane, and the end surface of the baffle facing the water outlet movably contacts the first plane.

[0009] In some embodiments, the first plane protrudes inward to form a boss, and the boss is arranged on a side of the water outlet away from the main water outlet end. The end of the boss close to the main water outlet end is rotatably connected to the rotating bracket, and the wall thickness of the shell at the position of the boss is less than or equal to the sum of the wall thickness at the position of the water outlet and the thickness of the baffle.

[0010] In some embodiments, a mounting position for mounting a reset elastic member is provided between the boss and the water outlet, and the reset elastic member abuts between the first plane and the movable water retaining member.

[0011] In some embodiments, the inner wall of the water channel switching section is provided with a first guide plane and a second guide plane parallel to each other, the first guide plane and the second guide plane are arranged along the vertical direction of the water outlet of the water hole, and the first guide plane and the second guide plane are both perpendicular to the first plane, and guide end surfaces are provided at both ends of the baffle, and the guide end surfaces are parallel to the first guide plane.

[0015] The beneficial effects of the embodiments of the utility model are:

[0016] In this drainage structure, in this embodiment, a water hole and a water outlet hole are arranged between the water inlet end and the main water outlet end of the water outlet device. When the user performs the water turning on operation, the movable water blocking member can utilize the water flow pressure during water flow to switch to the second position blocked on the water outlet hole to achieve normal water outlet. When the user performs the water stopping operation, the movable water blocking member can switch to the first position blocked on the water hole under the action of external force or based on its own gravity, so as to block the water inlet in time and enable the residual water close to the main water outlet side to be quickly discharged through the water outlet. The overall structure of the drainage structure is simple, which can effectively prevent the residual water from wetting the user after the water stopping operation is performed and reduce the scale inside the shell. When the filter element is connected to the inside of the shell, the excessive soaking of the filter element by the residual water can be reduced, thereby increasing the service life of the filter element while ensuring the water outlet filtering effect and avoiding the generation of secondary pollutants caused by the soaking of the filter element.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example 1

[0025] See also Figures 1 to 3 and Figure 5 As shown, the present embodiment discloses a drainage structure, including a shell, the shell is provided with a water inlet end 1 and a main water outlet end 2, a water path switching section 3 is provided between the water inlet end 1 and the main water outlet end 2, a water through hole 4 for connecting the water inlet end 1 and the main water outlet end 2 is provided inside the water path switching section 3, and a water outlet hole 5 is provided on the side wall of the water path switching section 3, the water outlet hole 5 is provided on the side of the water through hole 4 close to the main water outlet end 2, a movable water blocking member 6 is rotatably provided between the water through hole 4 and the water outlet hole 5, and the movable water blocking member 6 has a first position for blocking the water through hole 4 and a second position for blocking the water outlet hole 5.

[0026] When there is no water in the shell, the movable water blocking member 6 is kept in the first position under the action of external force or its own gravity, that is, it is blocked on the water hole 4, and the water inlet end 1 and the main water outlet end 2 are kept in a blocked state.

[0027] When the user performs the water turning on operation, water flows into the interior of the shell from the water inlet end 1, impacts the movable water retaining member 6 blocked on the water hole 4, and gives thrust to the movable water retaining member 6. The movable water retaining member 6 flips toward the direction close to the second position under the thrust of the water flow, switches from the first position to the second position, and blocks the water outlet 5. As a result, when the water flows through the position where the water outlet 5 is located, it will not discharge through the water outlet 5, but will flow to the main water outlet end 2 and flow out from the main water outlet end 2.

[0028] When the user performs the water cut operation, the water valve is closed, the water inlet end 1 loses continuous water inflow, the thrust given to the movable water retaining member 6 by the water flow becomes smaller, and the movable water retaining member 6 can be flipped again in the direction close to the first position under the action of external force or based on its own gravity, switching from the second position to the first position, and blocking the water hole 4 again. The water inlet end 1 and the main water outlet end 2 remain blocked, and the water outlet hole 5 is opened at the same time. At this time, even if the water outlet device is shaken, the water flow between the water inlet end 1 and the water path switching section 3 will not flow out, and the residual water between the main water outlet end 2 and the water path switching section 3 will flow back and flow out quickly through the water outlet hole 5.

[0029] In the first embodiment, the movable water stop 6 can complete the action of switching from the second position to the first position only by relying on its own weight. For example, when the user performs a water stop operation, the shell is rotated to make the water hole 4 open upward. At this time, the movable water stop 6 is affected by its own weight and flips in the direction close to the first position, thereby blocking the water hole 4 again.

[0030] In the second embodiment, the movable water retaining member 6 relies on the thrust brought by the residual water backflow to complete the action of switching from the second position to the first position.

[0031] In the present embodiment, a water hole 4 and a water outlet hole 5 are arranged between the water inlet end 1 and the main water outlet end 2 of the water outlet device. When the user performs the water turning on operation, the movable water blocking member 6 can utilize the water flow pressure during water flow to switch to the second position blocked on the water outlet hole 5 to achieve normal water outlet. When the user performs the water stopping operation, the movable water blocking member 6 is switched to the first position blocked on the water hole 4 under the action of external force or based on its own gravity, so as to block the water inlet in time and enable the residual water near the main water outlet end 2 to be quickly discharged through the water outlet hole 5. The overall structure of the drainage structure is simple, which can effectively prevent the residual water from wetting the user after the water stopping operation is performed and reduce the scale inside the shell. When the filter element is connected to the inside of the shell, the excessive soaking of the filter element by the residual water can be reduced, thereby increasing the service life of the filter element while ensuring the water outlet filtering effect and avoiding the generation of secondary pollutants caused by the soaking of the filter element.

[0032] In the third implementation mode adopted in this embodiment, please refer to Figures 1 to 3 and Figure 5 As shown, a reset elastic member 7 for driving the movable water retaining member 6 to flip in a direction close to the first position is also provided in the water channel switching section 3 .

[0033] When there is no water entering the shell, the reset elastic member 7 imparts a force to the movable water stop member 6 to flip in the direction close to the first position. The movable water stop member 6 is maintained in the first position under the action of the reset elastic member 7, that is, it is blocked on the water hole 4, and the water inlet end 1 and the main water outlet end 2 are kept in a blocked state.

[0034] When the user performs the water turning on operation, water flows into the interior of the shell from the water inlet end 1, impacts the movable water stop 6 blocked on the water hole 4, and gives thrust to the movable water stop 6 to overcome the force of the reset elastic member 7. The movable water stop 6 flips toward the second position under the thrust of the water flow, switches from the first position to the second position, and blocks the water outlet 5. As a result, when water flows through the position where the water outlet 5 is located, it will not discharge through the water outlet 5, but will flow to the main water outlet end 2 and flow out from the main water outlet end 2.

[0035] When the user performs the water cut operation, the water valve is closed, the water inlet end 1 loses continuous water inflow, the thrust given to the movable water retaining member 6 by the water flow becomes smaller, and the compressed reset elastic member 7 pushes the movable water retaining member 6, causing the movable water retaining member 6 to flip in the direction close to the first position, switching from the second position to the first position, and blocking the water hole 4 again. The water inlet end 1 and the main water outlet end 2 remain in a blocked state, and the water outlet hole 5 is opened at the same time. At this time, even if the water outlet device is shaken, the water flow between the water inlet end 1 and the water path switching section 3 will not flow out, and the residual water between the main water outlet end 2 and the water path switching section 3 will flow back and quickly flow out through the water outlet hole 5.

[0036] In the present embodiment, a water hole 4 and a water outlet hole 5 are arranged between the water inlet end 1 and the main water outlet end 2 of the water outlet device, and by utilizing the reset elastic member 7 and the water flow pressure during water flow, the movable water blocking member 6 can be switched to the second position blocked on the water outlet hole 5 under the action of the water flow thrust when the user performs the water turning on operation, so as to realize normal water discharge. When the user performs the water stopping operation, the reset elastic member 7 switches to the first position blocked on the water hole 4 under the action of the reset elastic member 7, so as to timely block the water inlet and enable the residual water near the main water outlet end 2 to be quickly discharged through the water outlet hole 5. The overall structure of the drainage structure is simple, which can effectively prevent the residual water from wetting the user after the water stopping operation is performed, and reduce the scale inside the shell. When the filter element is connected to the inside of the shell, the excessive soaking of the filter element by the residual water can be reduced, so as to increase the service life of the filter element while ensuring the water outlet filtering effect, and avoid the generation of secondary pollutants caused by the soaking of the filter element.

[0037] See also Figure 4 As shown, the movable water retaining member 6 includes a rotating bracket 61 and a baffle 62 that are interconnected. The rotating bracket 61 is rotatably arranged in the water path switching section. The rotating axis of the rotating bracket 61 is perpendicular to the water outlet direction of the water hole 4, ensuring that the movable water retaining member 6 can be flipped and switched between the first position and the second position under the action of the water flow and the reset elastic member 7, thereby realizing automatic water path switching of the shell when the user performs water turning on and water stopping operations.

[0038] See also Figure 2 and Figure 4As shown, the inner wall of the water channel switching section 3 bulges inward to form a first plane 31, and the water outlet 5 is arranged on the first plane 31. The end surface of the baffle 62 facing the water outlet 5 is movably in contact with the first plane 31. When the user performs the water-turning operation, the baffle 62 is in contact with the first plane 31 and is blocked outside the water outlet 5. When the user performs the water-stopping operation, the baffle 62 is separated from the first plane 31 and flipped in the direction close to the water hole 4 until it is blocked outside the water hole 4. The setting of the first plane 31 can ensure the airtightness of the water outlet 5 when the user performs the water-turning operation, thereby preventing water from flowing out through the water outlet 5 during normal use.

[0039] In addition, a sealing layer or a sealing ring matching the water outlet hole 5 may be provided on the end surface of the baffle 62 facing the water outlet hole 5 to improve the sealing effect.

[0040] See also Figure 2 As shown, the first plane 31 protrudes inward to form a boss 32, and the boss 32 is arranged on the side of the water outlet 5 away from the main water outlet end 2. The end of the boss 32 close to the main water outlet end 2 is rotatably connected to the rotating bracket 61. On the shell, the wall thickness H3 at the position of the boss 32 is less than or equal to the sum of the wall thickness H2 at the position of the water outlet 5 and the thickness H1 of the baffle 62, so as to avoid interference with the boss 32 when the baffle 62 is flipped.

[0041] See also Figure 4 and Figure 6 As shown, the inner wall of the water channel switching section 3 is provided with a first guide plane 33 and a second guide plane which are parallel to each other. The first guide plane 33 and the second guide plane are arranged along the vertical direction of the water outlet of the water hole 4, and the first guide plane 33 and the second guide plane are perpendicular to the first plane 31. Guide end surfaces are provided at both ends of the baffle 62, and the guide end surfaces are parallel to the first guide plane 33. The first guide plane 33 and the second guide plane can guide the flipping of the baffle 62, so that the flipping of the baffle 62 is more stable and smooth.

[0042] See also Figure 6 As shown, the inner wall cross-section of the water channel switching section 3 is a rectangular structure. Compared with other polygonal structures, the rectangular structure is easier to manufacture and can reduce the difficulty of component production while ensuring the airtightness of the water outlet 5 and the stability of the baffle 62 flipping.

[0043] The diameter of the water outlet hole 5 is 10mm~15mm. Exemplarily, the diameter of the water outlet hole 5 is 10mm, 11mm, 12mm, 13mm, 14mm or 15mm, but not limited to this. When the diameter of the water outlet hole 5 is too small, the residual water is difficult to be discharged from the shell in time. When the diameter of the water outlet hole 5 is too large, the water outlet hole 5 is difficult to be well sealed when the user performs the water turning operation.

[0044] See also Figure 2 and Figure 4As shown, the reset elastic member 7 is a column spring, and a mounting position for installing the reset elastic member 7 is provided between the boss 32 and the water outlet 5 , and the reset elastic member 7 is pressed against between the first plane 31 and the movable water stop 6 .

[0045] In this embodiment, one end of the resetting elastic member 7 is connected to the first plane 31 , and the other end is movably in contact with or connected to the movable water stop member 6 .

[0046] A water outlet device comprises the above-mentioned drainage structure.

[0047] Furthermore, the water outlet device may be a shower head, and the drainage structure is arranged on the handle of the shower head.

[0048] Example 2

[0049] The difference between this embodiment and embodiment 1 is that the reset elastic member is a torsion spring.

[0050] Of course, the above illustrations are only preferred implementation modes of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
