Description
Technical Field
[0001] This utility model relates to the field of bathroom technology, and more specifically to a hydraulically driven water spray body, a smart toilet seat, and a smart toilet. Background Technology
[0002] Currently, most mainstream smart toilets on the market use a pure water pressure driven cleaning spray bar. This means that the water force generated after the water flow is injected into the spray body directly pushes the spray bar forward along a preset trajectory to achieve the action of the spray bar extending and reaching the designated cleaning position.
[0003] However, in existing water jets that use pure water pressure as the driving force, the water flow directly impacts the nozzle of the spray bar during the process of the water force pushing the spray bar forward. Often, some water will flow out of the nozzle, which will reduce the water force that pushes the spray bar forward, which may result in the inability to extend the bar or the bar not extending to the required position. In addition, during the extension and retraction of the spray bar, a small amount of water will spray out of the nozzle hole, which may splash onto the user's clothes or other places, affecting the user experience. Utility Model Content
[0004] To solve the above problems, this utility model provides the following technical solution:
[0005] A hydraulically driven water spray body includes a main body with an inner cavity. One end of the main body has an outlet communicating with the inner cavity, and the other end has a water inlet connector. It also includes a retractable spray rod that moves within the inner cavity. The spray rod has an outlet and an inlet, the inlet being connected to the water inlet connector. A one-way valve, a duckbill type, is detachably connected to the inlet of the spray rod. The inner cavity also includes an elastic element that provides elastic force to the spray rod and a limiting part that limits the extension position of the spray rod. When water enters, the one-way valve closes, and external water with pressure flows into the inner cavity through the water inlet connector. The water pressure in the inner cavity acts on the one-way valve, overcoming the elastic force of the elastic element to push the spray rod. When the spray rod is limited to the extension position by the limiting part, the water pressure further overcomes the elastic force of the one-way valve, opening the one-way valve. External water enters the spray rod through the inlet and is then sprayed out through the outlet.
[0006] The present invention is further configured such that: the one-way valve includes a mounting cover and a duckbill baffle; the mounting cover is connected to the water inlet of the spray bar; the duckbill baffle is located between the mounting cover and the water inlet of the spray bar and covers the water inlet of the spray bar; the duckbill baffle includes a connecting part and a flexible part; the external water source controls the opening and closing of the water inlet of the spray bar through the opening and closing of the flexible part; when the spray bar is limited to the extended position, the water pressure in the inner cavity overcomes the elastic force of the flexible part; the flexible part opens and communicates with the water inlet; the external water source flows into the water inlet through the flexible part and is sprayed out from the water outlet.
[0007] The present invention is further configured such that: the mounting cover is provided with a buckle, the water inlet of the spray bar is provided with a hook that engages with the buckle, the mounting cover and the water inlet of the spray bar clamp and fix the connecting part, and the flexible part extends into the spray bar and communicates with the water inlet of the spray bar.
[0008] The present invention is further configured such that: the mounting cover is provided with a baffle, the baffle extending into the inside of the duckbill water-blocking component.
[0009] The present invention is further configured such that: a limiting surface protrudes from the periphery of the water inlet of the spray bar to cooperate with the limiting part, and a sealing gasket is provided on the side of the limiting surface facing the limiting part.
[0010] The present invention is further configured such that: the inner walls on both sides of the flexible part form a duckbill opening, the elastic force of the flexible part is f1, the hydrodynamic force of water flow impacting the duckbill opening is f2, when an external water source enters the inner cavity and the inner cavity is not full, f2≤f1 so that the duckbill opening is always in a closed state, and when the inner cavity is full of water, f2>f1 so that the duckbill opening is in an open state.
[0011] The present invention is further configured such that: the water inlet connector is integrally formed with the main body or is detachably connected to the main body, and the water inlet connector includes a cover and at least one functional water inlet.
[0012] This utility model also proposes an intelligent cover plate, which is provided with the above-mentioned water spray body, and at least one of the water spray bodies is provided on the base of the intelligent cover plate.
[0013] This utility model also proposes an intelligent toilet, which is equipped with the above-mentioned intelligent cover and also includes a toilet body. The intelligent cover is located at the rear end of the toilet body, and the water spray body can extend and retract from the base of the intelligent cover and is used to wash the human body.
[0014] Compared with the prior art, the present invention has at least the following advantages:
[0015] 1. By adding a one-way valve at the rear end of the spray bar, the external water source first impacts the one-way valve after entering the main body, generating a forward thrust on the spray bar, ensuring sufficient hydraulic power to push the spray bar, effectively solving the defect of insufficient extension of the bar, and ensuring normal extension and retraction of the spray bar under lower working water pressure; water will not flow out of the nozzle when the spray bar is extended, greatly improving the user experience.
[0016] 2. The one-way valve is designed with a flexible duckbill structure. Compared with ordinary one-way valves, the flexible part of the duckbill water baffle can automatically control the flow of water by the water pressure, reducing extra operations and making it more convenient to use.
[0017] 3. When the water first enters the inner cavity, the water pressure is low and the duckbill opening cannot be opened. As the spray bar extends, the water flows from the flow channel between the spray bar and the inner cavity to the gap between the main body outlet and the spray bar and exits from the gap, thus self-cleaning the outer wall of the spray bar. When the inner cavity is full of water, the water pressure increases and opens the duckbill opening, and the water flows into the spray bar to achieve water output from the spray bar.
[0018] 4. By setting a baffle that extends into the inside of the duckbill water baffle, it is ensured that the duckbill water baffle will not flip over when the water flows back. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.
[0029] A hydraulically driven water jet, such as Figure 1 and Figure 2 As shown, it includes a main body 1, an inner cavity 2 is provided inside the main body 1 along the axial direction, and a spray bar 5 that can be extended and moved in the inner cavity 2. The inner cavity 2 is a cylindrical cavity structure, which provides space for the extension and retraction of the spray bar 5.
[0030] One end of the main body 1 is provided with an outlet 3 communicating with the inner cavity 2. The diameter of the outlet 3 is slightly larger than the outer diameter of the spray bar 5 to ensure that the spray bar 5 can smoothly extend or retract from the outlet 3. The other end of the main body 1 is provided with a water inlet connector 4 communicating with the inner cavity 2. Specifically, the outlet 3 is located at the front end of the main body 1, i.e., the end facing the user, and the water inlet connector 4 is located at the rear end of the main body 1. In this embodiment, the water inlet connector 4 is detachably connected to the main body 1 and can be detachably installed by means of a buckle 9 or screws. In other embodiments, the water inlet connector 4 can also be connected to the main body 1 by injection molding. The water inlet connector 4 specifically includes a cover 401 and at least one functional water inlet 402. The cover 401 is connected to the rear end of the main body 1. External water source enters the inner cavity 2 through the functional water inlet 402. In this embodiment, there are two functional water inlets 402, one for posterior washing and the other for feminine washing. In this embodiment, there are also two spray bars 5 corresponding to the inner cavity 2, namely posterior washing spray bar 5 and feminine washing spray bar 5.
[0031] The front end of the spray bar 5 is provided with a water outlet 6, which is located on the nozzle at the front end of the spray bar 5. The size of the nozzle is larger than the size of the outlet 3 of the main body 1. During the extension and retraction of the spray bar 5, the nozzle is always located outside the main body 1. The spray bar 5 has a water inlet 7 at its rear end, which is connected to the water inlet connector 4. A one-way valve 8 can also be detachably connected to the water inlet 7 of the spray bar 5. In this embodiment, the one-way valve 8 is a duckbill type one-way valve. The inner cavity 2 is also provided with an elastic element 16 that provides elastic force to the spray bar 5 and a limiting part 12 that limits the extension position of the spray bar 5. When water enters, the one-way valve 8 is closed by elastic force. The external water source with water pressure flows into the inner cavity 2 through the water inlet connector 4. The water pressure in the inner cavity 2 acts on the one-way valve 8 to overcome the elastic force of the elastic element 16 and push the spray bar 5. When the spray bar 5 is limited to the extension position under the action of the limiting part 12, the water pressure further overcomes the elastic force of the one-way valve 8, and the one-way valve 8 opens. The external water source enters the spray bar 5 through the water inlet 7 and is then sprayed out through the water outlet 6.
[0032] like Figure 3 and Figure 4As shown, a limiting part 12 is provided at the front end of the inner cavity 2 (at the distance from the inward end of the outlet 3). A limiting surface 13 protrudes from the periphery of the spray bar inlet 7 to cooperate with the limiting part 12. When the spray bar 5 extends outward to the point where the limiting surface 13 cooperates with the limiting part 12, it cannot extend further outward, thereby reaching the maximum extension stroke and preventing it from falling off. A sealing gasket 14 is also provided on the side of the limiting surface 13 facing the limiting part 12. The sealing gasket 14 abuts against the limiting part 12. When the spray bar 5 is fully extended, it prevents water from flowing out of the gap between the spray bar 5 and the outlet 3, maintaining the water pressure at the outlet 6 of the spray bar 5.
[0033] In this embodiment, the elastic element 16 is specifically a spring. The elastic element 16 is sleeved on the outside of the spray bar 5, with one end of the elastic element 16 contacting the rear end of the spray bar 5 and the other end contacting the front end of the main body 1. When the water flow applies a pushing force to the spray bar 5 to extend it outward, the elastic element 16 is compressed. When the water flow is turned off, the elastic element 16 rebounds and pushes the spray bar 5 back into the inner cavity 2, realizing the automatic extension and retraction function of the spray bar 5.
[0034] like Figures 4 to 7 As shown, the one-way valve 8 specifically includes a mounting cover 801 and a duckbill baffle 802. The one-way valve 8 is connected to the water inlet of the spray bar 5 through the mounting cover 801. The duckbill baffle 802 is located between the mounting cover 801 and the water inlet 7 of the spray bar and covers the water inlet 7 of the spray bar 5. After the external water source enters the inner cavity 2, it will first impact the duckbill baffle 802 and will not directly reach the nozzle. This essentially converts the water flow impact force into a thrust on the spray bar 5, effectively solving the defect of the extension bar not reaching its full position, and ensuring the normal extension and retraction of the spray bar 5 under lower working water pressure.
[0035] The duckbill water-blocking component 802 specifically includes a connecting part 8021 and a flexible part 8022. The flexible part 8022 achieves opening and closing switching through elastic force. The external water source controls the opening and closing of the water inlet 7 of the spray bar 5 through the opening and closing of the flexible part 8022. When the spray bar 5 is limited to the extended position, the water pressure in the inner cavity 2 increases, thereby overcoming the elastic force of the flexible part 8022, causing the flexible part 8022 to open and connect with the water inlet 7. The external water source flows into the water inlet 7 through the flexible part 8022 and is sprayed out from the water outlet 6.
[0036] The mounting cover 801 is provided with multiple buckles 9, which are equidistantly arranged along the circumference of the mounting cover 801. The spray bar inlet 7 is provided with multiple hooks 10 that engage with the buckles 9 and correspond one-to-one, allowing the mounting cover 801 to be fixed to the spray bar inlet 7 by rotation. The mounting cover 801 and the spray bar inlet 7 clamp and fix the connecting part 8021 of the duckbill baffle 802, while the flexible part 8022 of the duckbill baffle 802 extends into the spray bar 5 and communicates with the spray bar 5 inlet 7.
[0037] The mounting cover 801 has a retaining edge 11 in the middle, which extends into the inside of the duckbill water baffle 802 to ensure that the duckbill water baffle 802 will not flip over when the water flows back.
[0038] The flexible part 8022 forms duckbill openings 15 on both sides of the inner wall. When the water flows from the rear end of the inner cavity 2 to the front end, the impact force is large enough to open the duckbill openings 15. However, it cannot be opened in the opposite direction, thus achieving the effect of a one-way valve 8. The elastic force of the flexible part 8022 is f1, and the hydrodynamic force of the water flow impacting the duckbill 15 is f2. When the external water source enters the inner cavity 2 and the inner cavity 2 is not full, f2≤f1, so the duckbill 15 is always closed. The impact force of the water flow pushes the spray bar 5 outward. At the same time, the water flow exits from the flow channel between the spray bar 5 and the inner cavity 2 through the gap between the outlet 3 of the main body 1 and the spray bar 5, thereby self-cleaning the outer wall of the spray bar 5. Since the duckbill 15 cannot be opened, no water flows out of the outlet 6 of the spray bar 5. When the inner cavity 2 is full of water, the water pressure increases. At this time, f2>f1, so the duckbill 15 is in an open state. At the same time, since the spray bar 5 extends to the position, the sealing gasket 14 and the limiting part 12 cooperate to seal, the gap stops water flow, and the self-cleaning of the outer wall of the spray bar 5 stops. The water flow enters the spray bar 5 from the open duckbill 15 and exits from the outlet 6 of the spray bar 5.
[0039] This embodiment also proposes an intelligent cover (not shown), which is equipped with the above-mentioned hydraulically driven water spray body, and at least one of the water spray bodies is disposed on the base of the intelligent cover.
[0040] This embodiment also proposes a smart toilet (not shown), which is equipped with the aforementioned smart seat and also includes a toilet body. The smart seat is located at the rear end of the toilet body, and the water jet can extend and retract from the base of the smart seat and be used to wash the human body.
[0041] The working process of this utility model is as follows:
[0042] During operation, external water enters through the water inlet connector 4. After water enters, the water flow exerts a forward thrust on the spray bar 5 (part of the water flows out from the gap between the spray bar 5 and the main body 1, which has a self-cleaning effect on the spray bar 5). Due to the duckbill water baffle 802, the water flow is blocked when water enters, reducing the amount of water flowing out of the nozzle. This concentrates the water pressure on the power of the spray bar 5 extending forward, which is beneficial for the normal extension and operation of the spray bar 5 under low water pressure conditions. It also prevents water from spraying out of the nozzle during the extension process and spraying onto the user's clothes, which would affect the user experience.
[0043] When the spray bar 5 extends forward to its position, the sealing gasket 14 presses against the limiting part 12 of the main body 1, blocking the self-cleaning water flow. At this time, the water pressure in the cavity of the main body 1 increases, opening the duckbill opening 15 of the duckbill water baffle 802, and the water flows from the middle channel of the spray bar 5 to the nozzle, realizing the nozzle rinsing function.
[0044] When the water source is turned off, the water pressure in the main body 1 chamber drops, and the spray bar 5 retracts under the action of the elastic element 16. The duckbill water-blocking element 802 closes, ensuring that water will not spray out from the nozzle during the retraction process, so that more water can be used for the self-cleaning of the spray bar 5, improving the user experience.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
[0046] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
