Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a spray nozzle device and a splash-proof toilet. Background Technology

[0002] Currently, most siphon toilets on the market have a brush ring water path and a jet siphon water path. A guide ring can be installed on the toilet bowl wall, and the brush ring nozzle is installed in the mounting hole on the guide ring. The brush ring nozzle is connected to the brush ring water path to spray water towards the guide ring. However, toilets usually use tap water pressure directly for flushing. Because tap water pressure can be unstable and fluctuate greatly, problems can easily occur. For example, if the water pressure is too low, the water flow from the brush ring nozzle will be small, making it difficult to flush the entire guide ring. Therefore, toilet design generally prioritizes ensuring that the entire surface of the toilet bowl can be flushed even under low water pressure.

[0003] However, with this design, if the water pressure is high, the water output of the brush ring nozzle increases, and the water flow of the guide ring increases significantly. After the primary water flow rotates once, it becomes a secondary water flow. The secondary water flow still has a lot of kinetic energy. After merging with the primary water flow, it will form a stronger water force. The merging of the two can easily cause water splashing. Moreover, the higher the water pressure, the more serious the splashing.

[0004] Therefore, it is necessary to design a splash-proof brush ring nozzle that can both maintain the rinsing effect at low pressure and prevent water splashing at high pressure. Summary of the Invention

[0005] The main objective of this invention is to overcome the aforementioned defects of brush ring nozzles in the prior art, and to propose a nozzle device and a splash-proof toilet that can divert the spray channel under high pressure to avoid splashing water. It has a simple structure and is easy to install.

[0006] The present invention adopts the following technical solution:

[0007] A nozzle device includes a main body with a spray channel, characterized in that it further includes a water-dividing component and an elastic component. The water-dividing component is movably sleeved on the main body and has at least one main spray hole and at least one diversion port, the main spray hole and the diversion port being respectively connected to the spray channel. The elastic component is disposed between the water-dividing component and the main body to drive the water-dividing component to move in the opposite direction to the flushing water flow of the spray channel to close the diversion port. The water-dividing component can overcome the elastic force of the elastic component and move in the flushing water flow direction of the spray channel under the water pressure of the spray channel to open the diversion port.

[0008] Preferably, the water distribution component is further provided with a plurality of water-blocking ribs, and at least one main injection hole is formed between the plurality of water-blocking ribs and the inner wall of the water distribution component, and the water pressure of the injection channel acts on the water-blocking ribs.

[0009] Preferably, at least one of the diversion ports is located on the side of the water distribution element and extends along the moving direction of the water distribution element.

[0010] Preferably, the inner wall of the spray channel is provided with a groove, one end of the water separator is inserted into the spray channel and a protrusion is provided on its outer periphery, the protrusion and the groove are in sliding fit; the elastic element is stretched on or connected between the opposite ends of the protrusion and the groove.

[0011] Preferably, the main body is further provided with a baffle, the baffle being detachably fitted onto the water outlet end of the main body through the middle; the elastic element is stretched between the protrusion and the end face of the baffle.

[0012] Preferably, the water distribution component includes a first cover and a second cover. The first cover is provided with the main injection hole and the diversion port, and its inner end is inserted into the injection channel. The second cover is detachably fixed to the outer periphery of the inner end of the first cover, and the second cover constitutes the protrusion.

[0013] Preferably, the outer periphery of the outer end of the first cover body is provided with a baffle extending radially outward, the baffle being located outside the main body; the diversion port is located on the connecting surface between the protrusion and the baffle.

[0014] A splash-proof toilet includes a toilet body, a water guide ring on the wall of the toilet body, and a mounting hole on the water guide ring. The toilet body also includes a spray nozzle device, with the main body passing through the mounting hole and the main spray nozzle facing the water guide ring.

[0015] Preferably, a shielding part is provided on the side opposite to the sidewall of the water guide ring at the outer end of the mounting hole. The shielding part is opposite to the diversion port to reduce the water pressure of the water outlet of the diversion port. A space is formed between the shielding part and the sidewall of the water guide ring for the water diverter to move.

[0016] Preferably, it further includes a sealing ring and a locking member, wherein the sealing ring is sleeved between the outer periphery of the main body and the inner wall of the mounting hole, and the locking member is detachably sleeved on the outside of the main body and presses tightly against the inner end of the mounting hole.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, a water distribution component and an elastic component are added. The water distribution component has at least one main jet hole and at least one diversion port. The elastic component is disposed between the water distribution component and the main body to drive the water distribution component to move and close the diversion port. The water distribution component can overcome the elastic force of the elastic component to move under the water pressure of the jet channel to open the diversion port, thereby achieving low-pressure flushing without affecting it and avoiding high-pressure water splashing.

[0019] 2. In this invention, a water-blocking rib is provided inside the water distribution component. The water pressure of the spray channel can act on the water-blocking rib to drive the water distribution component to move, thereby changing the size of the flow end face of the diversion port. A main spray hole can also be formed between the water-blocking rib and the inner wall of the spray channel. The structure is ingenious.

[0020] 3. In this invention, the main jet hole is located at the end of the water distribution component and serves as the main water outlet channel. A diversion port is set on the side of the water distribution component for diversion under high pressure. The greater the water flow pressure in the jet channel, the larger the flow end face and the greater the discharge flow, which effectively reduces and stabilizes the water flow of the main jet hole, thereby achieving high-pressure anti-splashing.

[0021] 4. In this invention, the inner wall of the spray channel is provided with a groove, and the water distribution component is provided with a protrusion that slides in cooperation with the groove, which can ensure that the sliding between the water distribution component and the main body is more stable and reliable, and can also prevent the water distribution component from detaching from the main body.

[0022] 5. In this invention, the baffle is detachably fitted onto the main body's water outlet end. The water distribution component includes a first cover and a second cover that are detachably connected. A baffle is provided on the outer periphery of the outer end of the first cover. The baffle can abut against or detach from the baffle to close or open the diversion port. Each part is easy to mold and convenient to assemble, taking into account both functionality and manufacturability.

[0023] 6. In this invention, a shielding part is provided on the mounting hole of the toilet body, so that the outer perimeter of the mounting hole is blocked. If the water pressure is high, the flushing water flow can be divided into two paths through the main jet nozzle and the branch nozzle. A portion of the water flow is sprayed out from the main jet nozzle, and the remaining water flow is sprayed out from the branch nozzle and weakened. Under the action of gravity, it flows down the wall to form a cascading water flow. The primary water flow sprayed out from the main jet nozzle can form a secondary water flow after rotating once. The secondary water flow hits the cascading water flow, which has almost no rotational kinetic energy, and its energy is greatly reduced. After the secondary water flow with reduced energy merges with the primary water flow, it will not form a larger water force, so there will be no splashing. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0038] The present invention will be further described below through specific embodiments.

[0039] In this invention, the terms "first," "second," and "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "left," "right," "inner," "outer," "front," and "rear" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this invention. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0041] See Figures 1 to 5 A nozzle device for spraying flushing water mainly includes a main body 10, a water distribution component 20, and an elastic component 30. The main body 10 may be tubular and has a spray channel 11. The spray channel 11 extends along the axial direction of the main body 10 and penetrates the main body 10, that is, the main body 10 is open at both ends. One end serves as the water inlet of the spray channel 11 for connecting to relevant pipes, and the other end serves as the water outlet of the spray channel 11 for installing the water distribution component 20.

[0042] The water distribution component 20 is movably sleeved on the main body 10. It can be located at the water outlet end of the main body 10 and is provided with at least one main jet hole 21 and at least one diversion port 22. The main jet hole 21 is connected to the jet channel 11 and serves as the main water outlet channel of the nozzle device. The diversion port 22 is also connected to the jet channel 11. The diversion port 22 can be located on the side of the water distribution component 20 and extends along the moving direction of the water distribution component 20. The diversion port 22 is used to divert the water from the jet channel 11, which can reduce the water flow rate of the main jet hole 21.

[0043] In this invention, at least one diversion port 22 may be distributed circumferentially along the water distribution component 20. The water outlet direction of the diversion port 22 may be different from the water outlet direction of the main jet hole 21. The two may have an included angle, which may be an acute angle, an obtuse angle, or a right angle. Preferably, the water outlet direction of the diversion port 22 is set to be perpendicular to the water outlet direction of the main jet hole 21.

[0044] Furthermore, the water distribution component 20 is also provided with several water-retaining ribs 23. At least one main jet hole 21 is formed between the water-retaining ribs 23 and the inner wall of the water distribution component 20. The main jet hole 21 extends axially, and the water pressure of the jet channel 11 acts on the water-retaining ribs 23 to drive the water distribution component 20 to move relative to the main body 10. One end of each water-retaining rib 23 can be connected to the inner wall of the water distribution component 20, and the other end extends radially inward along the water distribution component 20 and converges at the center point. The number of main jet holes 21 formed can be related to the number and shape of the water-retaining ribs 23. The number of main jet holes 21 can be one, two, three, or more, and their sizes can be the same or different, which is not limited here. In practical applications, the distribution of multiple water-retaining ribs 23 within the water distribution component 20 is not limited to this; they can also be interwoven to form a grid-like pattern, etc., which can be selected as needed.

[0045] In this invention, the inner wall of the spray channel 11 is also provided with a groove 17, which extends along the axial direction of the main body 10. A protrusion 25 is provided on the outer periphery of one end of the water distribution component 20. The protrusion 25 is slidably engaged with the groove 17, and the protrusion 25 is confined within the groove 17. That is, when the water distribution component 20 moves relative to the main body 10, the protrusion 25 slides along the groove 17 to prevent the water distribution component 20 from detaching from the main body 10.

[0046] Furthermore, the water distribution component 20 can be an integral structure or a split structure. Taking the split structure as an example, it includes a first cover 26 and a second cover 27. The first cover 26 is a hollow structure and has a main injection hole 21 and a diversion port 22. The main injection hole 21 extends axially along the first cover 26, and the diversion port 22 radially penetrates the first cover 26. The inner end of the first cover 26 is inserted into the injection channel 11. The second cover 27 is annular and is detachably fixed to the inner end of the first cover 26 and has a protrusion 25. The second cover 27 protrudes outward relative to the first cover 26 to form the protrusion 25, or the outer periphery of the second cover 27 is additionally provided with a protrusion 25.

[0047] In this invention, the first cover 26 and the second cover 27 can be connected by common detachable fixing methods such as snap-fit ​​connection or sleeve connection. Taking snap-fit ​​connection as an example, the inner wall of the first cover 26 can be provided with a snap groove 13, and the second cover 27 can be provided with a snap strip 14. The detachable fixing connection is achieved by inserting the snap strip 14 into the first cover 26 and engaging with the snap groove 13.

[0048] Furthermore, the present invention provides a baffle 28 extending radially outward on the outer periphery of the outer end of the first cover 26, the baffle 28 being located outside the main body 10. The diversion port 22 is located on the connecting surface between the protrusion 25 and the baffle 28. Moreover, the present invention can be configured such that when the baffle 28 abuts against the water outlet end face of the main body 10, the diversion port 22 is closed within the spray channel 11, and water cannot flow from the diversion port 22; when the baffle 28 leaves the water outlet end face of the main body 10, the diversion port 22 is exposed and opened, and water can flow from the diversion port 22. Furthermore, the larger the exposed area of ​​the diversion port 22, the larger the flow end face, which is more conducive to the water flowing out from the side of the diversion body to achieve diversion.

[0049] In this invention, a baffle 12 can also be provided at the water outlet end of the main body 10. The baffle 12 is detachably fitted onto the water outlet end of the main body 10, with its center through the baffle 28. The baffle 12 can be located between the baffle plate 28 and the water outlet end of the main body 10. The baffle 12 can serve as one of the inner walls of the groove 17 and is opposite to the protrusion 25. The baffle 12 and the main body 10 can be connected by common detachable fixing methods such as snap-fit ​​connection or sleeve connection. Taking snap-fit ​​connection as an example, a snap groove 13 can be provided on the outer periphery of the water outlet end of the main body 10, and a snap strip 14 is correspondingly provided on the baffle 12. The detachable fixing connection is achieved by inserting the snap strip 14 into the snap groove 13.

[0050] The elastic element 30 of the present invention is disposed between the water divider 20 and the main body 10 to drive the water divider 20 to move in the opposite direction to the flushing water flow of the spray channel 11 to close the diversion port 22. After the diversion port 22 is closed, no water flows out. The water divider 20 can overcome the elastic force of the elastic element 30 and move in the flushing water flow direction of the spray channel 11 under the water pressure drive of the spray channel 11 to open the diversion port 22 and adjust the size of its flow end face. The greater the water pressure of the spray channel 11, the larger the flow end face of the diversion port 22; the lower the water pressure of the spray channel 11, the smaller the flow end face of the diversion port 22, or even close it.

[0051] Specifically, the elastic element 30 is sleeved on the outer periphery of the water distribution element 20, and is stretched or connected between the opposite ends of the protrusion 25 and the groove 17, i.e., the end face of the cover 12. The groove 17 also provides clearance for the elastic element 30. When the water distribution element 20 moves, the elastic element 30 can be compressed or released. The elastic element 30 can be a spring.

[0052] Based on this, the present invention also proposes a splash-proof toilet, see [link to relevant documentation]. Figures 8-10 The toilet includes a toilet body 40 and a spray head device as described above. The wall surface 44 of the toilet body 40 is provided with a water guide ring 41. The water guide ring 41 is close to the top of the wall surface 44 and extends circumferentially along the wall surface 44. The water guide ring 41 is provided with a mounting hole 42. The body 10 of the spray head device passes through the mounting hole 42. The main jet hole 21 faces the water guide ring 41, that is, the main jet hole 21 can spray flushing water towards the water guide ring 41 to achieve the brushing effect.

[0053] Furthermore, a shielding part 43 is provided on the side opposite to the sidewall of the water guide ring 41 at the outer end of the mounting hole 42. That is, shielding structures are provided around the outer end of the mounting hole 42, including the upper, lower, left, and right sides, except for the front side where the water guide ring 41 is located. The shielding part 43 is provided opposite to the diversion port 22, which can be used to weaken the water pressure of the water exiting the diversion port 22. That is, when multiple diversion ports 22 are discharging water, the water output can be weakened by the shielding structure and then flow down along the wall surface 44. In this invention, a space for the water distribution component 20 to move is formed between the shielding part 43 and the sidewall of the water guide ring 41. The size and shape of the shielding part 43 can be set according to requirements and are not limited here.

[0054] In this invention, to better install the nozzle device, a sealing ring 15 and a locking member 16 are also included. The sealing ring 15 is sleeved between the outer periphery of the main body 10 and the inner wall of the mounting hole 42, and it can be located at the outer end of the mounting hole 42 to achieve a seal. The locking member 16 is detachably sleeved on the outside of the main body 10 and presses tightly against the inner end of the mounting hole 42. The locking member 16 is threaded, and the outer periphery of the main body 10 is correspondingly threaded, and the two are threadedly engaged.

[0055] The working principle of the spray nozzle device and splash-proof toilet of the present invention is as follows:

[0056] Under normal circumstances, see Figure 2 Under the action of the elastic element 30, the baffle 28 of the water distribution element 20 abuts against the baffle cover 12, and the diversion port 22 is hidden inside the main body 10, that is, the diversion port 22 is closed.

[0057] When the toilet is turned on and water flows from the brush ring, the flushing water enters the spray channel 11, and depending on the water pressure, there are two specific situations:

[0058] If the water pressure is low, see Figure 6 If the force exerted by the water pressure on the water-blocking rib 23 is less than the elastic force of the elastic element 30, then the water-dividing element 20 remains stationary, the diversion port 22 remains closed, and the flushing water is sprayed out through the main jet hole 21 to the water guide ring 41, and flows along the water guide ring 41 to flush the wall surface 44.

[0059] If the water pressure is high, see Figure 7 , Figure 11 When the water pressure exerts a greater force on the baffle rib 23 than the elastic force of the elastic element 30, the water divider 20 can be driven to move axially outward relative to the main body 10. The elastic element 30 is compressed, and the diversion port 22 is exposed outside the main body 10, meaning the diversion port 22 is opened. A portion of the flushing water flow a is ejected through the main jet hole 21 to the water guide ring 41, while another portion is ejected through the diversion port 22 to the periphery of the mounting hole 42. After being weakened, the water flows down the wall surface 44 under gravity, forming a discharge flow c. Flow a rotates once to form a secondary flow b. Flow b impacts the discharge flow c, which has virtually no rotational kinetic energy, resulting in a significant energy reduction. After the energy-reduced secondary flow b merges with the primary flow a, it does not create a larger water pressure, thus preventing splashing. The higher the water pressure in the flushing water path, the larger the exposed area of ​​the diversion port 22, and the larger the flow end face of the diversion port 22.

[0060] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
