Description

Technical Field

[0001] The invention relates to a water outlet device, in particular to a shower head. Background Art

[0002] There is a gingival groove about 2 mm deep at the junction of the teeth and gums. It is the main path for bacteria to enter the root of the teeth. It is easy to harbor dirt and stains, and is the place most likely to cause tooth and gum diseases.

[0003] The gingival sulcus and the gaps between teeth are the two most difficult places to clean. Studies have shown that "up to 40% of the tooth surface cannot be cleaned with a toothbrush." ​​Although dental floss (or toothpicks) can remove deposits on the tooth surface, from a microscopic perspective, the uneven tooth surface is still not clean, and bacteria only need a very thin layer of nutrient film to grow, and the harmful effects of the residual dirt film still partially exist.

[0004] In principle, the pressurized water flow that is both powerful and capable of drilling into holes is the most ideal way to clean the mouth. According to research by relevant institutions, the pressurized water column can flush into the gingival sulcus to a depth of 50-90%. The pressurized water column can not only clean various gaps, holes, and uneven surfaces, but also achieve a thorough "cleaning" at the micro level rather than just a rough "clearing" at the macro level. In addition to cleaning the teeth and mouth, the water flow of the water flosser also has a massage effect on the gums, promoting blood circulation in the gums and enhancing the local tissue's resistance to disease. At the same time, it can also eliminate bad breath caused by poor oral hygiene.

[0005] Food debris stuck in the gaps between teeth, in addition to being uncomfortable and carrying bacteria, is more harmful because it provides nutrients to dental plaque. If not removed in time, dental plaque can easily calcify and become "tartar" that accumulates at the root of the tooth, compressing and irritating the periodontal environment and causing periodontal atrophy.

[0006] Toothbrush is a must-have hygiene product for many families. The cleaning function of toothbrush is mainly achieved by the impact force of a high-speed water column ejected under a certain pressure. However, the electric toothbrush on the market is expensive and needs to be charged or battery-powered. Now, there is a faucet with a water flosser on the market, which can realize both the functions of conventional water discharge and water flosser. However, the existing faucet with water flosser can be installed with a nozzle regardless of whether it is in the water-on state or the water-off state. When the nozzle is installed in the water-on state, it is easy for water to flow out and cause misoperation. Summary of the invention

When the shower function is used to discharge water, the operating part cannot be moved to the position of opening the interface to prevent misoperation.

[0013] In a preferred embodiment: when the water is turned off and the operating member moves from a position closing the second interface to a position opening the second interface, the operating member drives the switching member to move to a position where the second water outlet waterway is connected to the water inlet, and the switching member cooperates with the limiting member to fix the limiting member in the initial position.

[0014] In a preferred embodiment: when the limit member moves from the initial position to the limit position, the limit member squeezes the first spring to accumulate elastic restoring force; when the switching member moves to the position connecting the second water outlet waterway and the water inlet, the switching member squeezes the second spring to accumulate elastic restoring force.

[0015] In a preferred embodiment: the operating member is a dial button, and the switching member is a switching shaft; the operating member and the switching member are connected via a reversing member to reverse the rotation of the dial button into the axial movement of the switching shaft.

[0016] In a preferred embodiment: the switching member is a protrusion arranged on the dial button and a slider arranged between the dial button and the switching shaft.

[0017] In a preferred embodiment: when water is flowing and the operating member is in the position to close the second interface, the limiting member has translational freedom under the action of water pressure to move from an initial position to a limiting position; the limiting member has a chamber for the switching member to move into, and when the limiting member is in the initial position, the chamber is aligned with the switching member, and when the limiting member is in the limiting position, the chamber is staggered with the switching member.

[0018] In a preferred embodiment: the switching member has a water flow channel connected to the water inlet, and a water outlet for connecting the water flow channel with the first water outlet waterway or the second water outlet waterway; when the operating member is in a position to close the second interface, the switching member moves to a position connecting the first water outlet waterway and the water inlet under the action of an elastic restoring force.

[0019] In a preferred embodiment: the limiting member is arranged at the connection between the water flow channel and the water inlet; when the limiting member is at the limiting position, the water flow area at the connection between the water flow channel and the water inlet is S1, and when the limiting member is at the initial position, the water flow area at the connection between the water flow channel and the water inlet is S2, S1>S2.

[0023] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0024] 1. The present invention provides a water outlet device capable of disassembling and assembling a water outlet terminal. Through the cooperation of a limiter, an operating member and a switching member, when water is flowing, the limiter moves to a limit position under the action of water pressure. At this time, the limiter and the operating member cooperate in a limit position, the switching member is fixed at a position that connects the first water outlet waterway with the water inlet, and the switching member also fixes the operating member at a position that closes the interface. In this way, when water is flowing, the user cannot open the interface through the operating member and then insert the water nozzle of the water flosser. Avoid opening the interface in the water flow state to cause water to spray at the interface and form an erroneous operation. Then when the water is turned off, the water pressure disappears, the limiter is reset to the initial position driven by the reset force of the first spring, the limiter and the switching member release the limit cooperation state, and the switching member and the operating member also release the limit cooperation state. At this time, the user can open the interface through the operating member, and drive the switching member to move to a position that connects the second water outlet waterway with the water inlet through the operating member, and the water nozzle of the water flosser can be inserted to use the water flossing function normally. And when the switching member moves to the position connecting the second water outlet waterway and the water inlet, the switching member forms a limiting cooperation with the limiting member again to fix the limiting member in the initial position, so as to avoid the limiting member moving to the limiting position again after water is passed.

[0025] 2. The present invention provides a water outlet device with a detachable water outlet terminal. When the limiter is in the initial position, the connection area between the water flow channel of the switching shaft and the water inlet can be reduced, thereby reducing the flow rate flowing into the second water outlet waterway, thereby adapting to the flow rate requirement when the tooth flushing function is used.

[0026] 3. The present invention provides a water outlet device with a detachable water outlet terminal. When using a shower function or a tooth flushing function, water can be stopped by a water stop component, which is convenient to use.

When the switching element moves to a position where the second water outlet waterway is connected to the water inlet, the second spring is squeezed. When the user pulls out the water nozzle of the water flosser, the switching element is reset under the drive of the second spring, thereby also driving the operating element to reset and close the interface.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] refer to Figure 1-Figure 11 The present embodiment provides a shower head with a water flossing function, comprising: a shower head body 1, a water flossing nozzle 2; the shower head body 1 has a water inlet 11, a first water outlet waterway 12 and a second water outlet waterway 13, and a switching member 14 for connecting the first water outlet waterway 12 or the second water outlet waterway 13 with the water inlet 11;

[0043] The shower body 1 also has an interface 15 for connecting the water nozzle 2 of the water flosser, an operating member 17 for opening or closing the interface 15, and a stopper 16; the interface 15 is connected to the second water outlet channel 13;

[0044] When water flows and the operating member 17 is in the position to close the interface 15, the limiting member 16 moves from the initial position to the limiting position, fixes the switching member 14 in the position connecting the first water outlet waterway 12 and the water inlet 11, and cooperates with the operating member 17 to fix the operating member 17 in the position to close the interface 15. At this time, the operating member 17 is in a locked state.

[0045] In the shower head with water flushing function, when the water is turned off, if the user places the operating member 17 in the position of closing the interface 15 and turns on the water, the limit member 16 will be moved to the limit position under the action of water pressure when the water is turned on. At this time, the limit member 16 and the switching member 14 are limited and matched, and the switching member 14 is fixed in the position of connecting the first water outlet waterway 12 and the water inlet 11, and the switching member 14 also fixes the operating member 17 in the position of closing the interface 15. In this way, when the water is turned on, the user cannot open the interface 15 through the operating member 17 and then insert the water nozzle 2 of the water flushing device. It is avoided that the interface 15 is opened by mistake in the water-turning state, causing water to spray at the interface 15.

[0046] The water is turned off and the limiter 16 is reset to the initial position. At this time, the switching member 14 and the limiter 16 are released from the limiter cooperation, and the operating member 17 is in a released state. The user can rotate the operating member 17 from the position of closing the interface 15 to the position of opening the interface 15, and the operating member 17 drives the switching member 14 to move to the position where the second water outlet waterway 13 is connected to the water inlet 11.

[0047] When the limiter 16 moves from the initial position to the limit position, the limiter 16 squeezes the first spring 161 to accumulate elastic reset force; thus, when the water is turned off, the water pressure disappears, and the limiter 16 is reset to the initial position driven by the reset force of the first spring 161, and the limiter 16 and the switch member 14 are released from the limit matching state, and the switch member 14 and the operating member 17 are also released from the limit matching state. Therefore, in the water-off state, the user can open the interface 15 through the operating member 17, and drive the switching member 14 to move to the position where the second water outlet waterway 13 and the water inlet 11 are connected through the operating member 17, and the water flosser 2 can be plugged in to use the water flosser function normally.

[0048] In a preferred embodiment, when the switching member 14 moves to the position connecting the second water outlet waterway 13 and the water inlet 11, the switching member 14 can again form a limiting fit with the limiting member 16 to fix the limiting member 16 in the initial position, thereby preventing the limiting member 16 from moving to the limiting position again after water flows.

[0049] In order to realize that when the switching member 14 moves to the position connecting the second water outlet waterway 13 and the water inlet 11, the switching member 14 forms a limiting fit with the limiting member 16 again to fix the limiting member 16 in the initial position. In this embodiment, the switching member 14 is a switching shaft, and the moving direction of the switching member 14 is along the axial direction of the switching member 14 itself. The moving direction of the limiting member 16 under the action of water pressure is perpendicular to the axial direction of the switching member 14, and the limiting member 16 has a chamber 162 for the switching member 14 to move into. When the limiting member 16 is in the initial position, the chamber 162 is aligned with the switching member 14. At this time, the switching member 14 can be inserted into the chamber 162 when it moves along the axial direction, so that the switching member 14 moves to the position connecting the second water outlet waterway 13 and the water inlet 11, and forms a limiting fit with the limiting member 16 to keep the limiting member 16 in the initial position. When the limiting member 16 is at the limiting position, the chamber 162 is offset from the switching member 14 . At this time, the switching member 14 and the limiting member 16 are limitedly matched, and the switching member 14 is fixed at a position that connects the first water outlet waterway 12 and the water inlet 11 .

[0050] After using the water flossing function, the user needs to remove the water spout 2 of the water flosser to ensure hygiene. If the user is required to manually turn the operating member 17 back to the position of closing the interface 15, it will be troublesome. Therefore, it is necessary to realize that when the user pulls out the water spout 2 of the water flosser, the operating member 17 can automatically close the interface 15 to prevent the user from forgetting and causing the interface 15 to be dirty. To this end, when the switching member 14 moves to the position that connects the second water outlet waterway 13 and the water inlet 11, the switching member 14 squeezes the second spring 141 to accumulate elastic reset force. In addition, the operating member 17 is a dial button, and the switching member 14 is a switching shaft; the operating member 17 and the switching member 14 are connected by a reversing member to reverse the rotation of the dial button to the axial movement of the switching shaft. Since the operating member 17 is restricted to the position of opening the interface 15 after the water spout 2 of the water flosser is inserted into the interface 15, the second spring 141 cannot drive the switching member 14 to reset. After the user pulls out the water nozzle 2 of the oral irrigator, the second spring 141 can release the reset force normally to drive the switching member 14 to reset. After the switching member 14 is reset, the operating member 17 can be reset to the position of closing the interface 15 through the reversing member.

[0051] Specifically, the switching member in this embodiment is a protrusion 171 provided on the dial button and a slider 142 provided between the dial button and the switching shaft. When the dial button rotates, the protrusion 171 will press against the slider 142 as the dial button rotates, thereby driving the switching shaft to translate along the axial direction, thereby achieving the purpose of driving the switching shaft to move by turning the dial button. When the dial button is released, when the switching shaft moves driven by the second spring 141, the slider 142 presses against the protrusion 171 as the switching shaft translates, thereby driving the dial button to rotate and driving the dial button back to the position of closing the interface 15.

[0052] Since the required water flow rate is significantly different in the shower function and the tooth flushing function, the water flow rate required in the tooth flushing function is relatively small, and the water flow rate required in the shower function is relatively large. Therefore, it is necessary to reduce the water flow rate when the tooth flushing function is used. To this end, the switching member 14 has a water flow channel 143 connected to the water inlet 11, and a water outlet for connecting the water flow channel 143 with the first water outlet waterway 12 or the second water outlet waterway 13; the limiting member 16 is arranged at the connection between the water flow channel 143 and the water inlet 11; when the limiting member 16 is in the limiting position, the water flow area at the connection between the water flow channel 143 and the water inlet 11 is S1, and when the limiting member 16 is in the initial position, the switching member 14 moves into the chamber 162 to keep the limiting member 16 in the initial position, and the water flow area at the connection between the water flow channel 143 and the water inlet 11 is S2, S1>S2. In this way, the position change of the switching member 14 and the limiting member 16 in the two matching states is utilized to change the water flow area at the connection between the water flow channel 143 and the water inlet 11, so as to dynamically adjust the water flow rate under different functions to adapt to the corresponding functions, which is more humane.

[0053] In order to further facilitate the use by the user, the present embodiment further includes a water-stop component 18, which is used to connect or disconnect the water inlet 11 with the switching member 14; thus, the water-stop component 18 can be operated during use to achieve temporary water stopping.

[0054] In this embodiment, the water stop assembly 18 includes a button 181, a valve core 182 and a third spring 183; the button 181 is used to drive the valve core 182 to move from the open position to the closed position and squeeze the third spring 183 to accumulate elastic reset force. In order to reduce the force required by the user when the water stop operation, a water hole 184 is set on the valve core 182 in this embodiment, and a space 185 connected to the water hole 184 is formed between the valve core 182 and the shower body 1. When the water is turned on, the water flows through the water hole 184 to fill the space 185, and the entire valve core 182 is only subjected to downward water pressure with an area of ​​S. Pressing the button 181 needs to overcome the pressure generated by this part of the water flow and the elastic force generated by the compression of the third spring 183. At the same time, the pressure generated by the downward water flow of the valve core 182 over the area of ​​S helps the valve core 182 to reset to the initial position after the hand is released. Therefore, the elastic force value of the third spring 183 required to be set can be slightly smaller, so that the switching force of the water stop switch is light under no-load. When water is stopped, S3=S4 on the valve core 182, and the entire valve core 182 is in a water pressure balance state. Therefore, the button 181 only needs to overcome the elastic force of the third spring 183 at the moment of opening; after opening, long pressing needs to overcome the elastic force of the third spring 183 and the water pressure generated by the water flow acting on the S area. Finally, the interface 15 described in this embodiment is a second interface, which is arranged at the front end of the shower body 1 along the axial direction, and is connected to the second water outlet terminal, that is, the water nozzle 2 of the water flosser; the shower body 1 is also provided with a first interface connected to the first water outlet waterway 12, the first interface is arranged vertically along the axial direction of the body, and is connected to the first water outlet terminal 19, the first water outlet terminal 19 includes a bubble water outlet and a shower water outlet arranged in concentric circles, and a knob 191 for switching the bubble water outlet and the shower water outlet. Switching between shower water and bubble water belongs to the prior art, and this part of the structure is not further expanded in this embodiment.

[0055] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
