Description

Technical Field

[0001] The utility model relates to the field of spray heads, in particular to a pressure regulating component, a pressure regulating spray head and a brush ring mechanism used for the spray head. Background Art

[0002] Existing smart toilets and multifunctional toilets use mainstream control valves such as pulse valves or pump-flush switching valves to control flushing, and cooperate with water outlet nozzles on the pot surface to wash the ceramic pot surface.

[0003] Regarding the method of using a pulse valve to control the water output of the brush ring, the unstable high and low water pressures will lead to unstable water in the brush ring. If the water is discharged at high pressure, the large amount of water on the pot surface is easy to drift and splash, affecting the user experience; if the water is discharged at low pressure, the brush ring has weak strength and the ability to clean the pot surface is poor, which can easily lead to incomplete cleaning of the pot surface and affect product quality. At present, there are also a series of methods to improve it, such as adding filters and brush heads to the brush ring nozzle. This method softens the high-pressure water output to a certain extent, but it also makes the low-pressure water output weaker.

[0004] Regarding the method of using a pump-flushing switching valve to control the water output of the brush circle, the water output of the nozzle is relatively stable, but the water pressure of the pump-flushing water is higher than that of municipal tap water, usually reaching 0.3Mpa&25L / Min, which is easy to cause drifting and splashing, affecting the user experience.

[0039] The present invention is further described below through specific implementation methods.

[0040] See also Figures 1 to 6 , a pressure regulating component applied to a nozzle, installed in the water channel of the nozzle, and used to reduce the pressure of the water flow in the water channel. It mainly includes a frame 10 and a diverter assembly 20. The frame 10 is a hollow structure, and the main shape of the frame 10 is set according to the shape of the water channel of the nozzle. The diverter assembly 20 is located in the frame 10 and divides the interior of the frame 10 into a main channel 21 and a diverter channel 22. The main channel 21 axially passes through the frame 10, and it can be located in the middle of the frame 10. The diverter channel 22 surrounds the outer periphery of the main channel 21 and extends radially along the frame 10. The diverter channel 22 is connected to the main channel 21.

[0041] The frame 10 is a hollow structure, which includes a plurality of connecting rods 11 and a connecting sleeve 12; the connecting sleeve 12 is located at one end of the frame 10 in the axial direction, the connecting sleeve 12 is a hollow ring, a plurality of connecting rods 11 are connected to the connecting sleeve 12 and are distributed at intervals along the circumference thereof, the connecting rod 11 can be vertically connected to the connecting sleeve 12, and the plurality of connecting rods 11 and the connecting sleeve 12 form a hollow interior. The size of the connecting sleeve 12 can be designed according to the internal size of the nozzle to be installed, and the number of the plurality of connecting rods 11 can be two, three, or even four, etc., which can be set according to the size of the connecting sleeve 12.

[0042] The diverter assembly 20 is connected to a plurality of connecting rods 11, and the inner side of the diverter assembly 20 in the radial direction is opposite to the main channel 21. The outer side of the diverter assembly 20 in the radial direction is connected to a plurality of connecting rods 11. Specifically, the diverter channel 22 includes a first diverter channel 23 and a second diverter channel 24, and the first diverter channel 23 and the second diverter channel 24 are both radially extended, and the first diverter channel 23 and the second diverter channel 24 are axially spaced and distributed along the frame 10, and the first diverter channel 23 and the second diverter channel 24 are arranged on the outer side of the frame 10 in the radial direction to be connected to each other. Assuming that the first diverter channel 23 and the second diverter channel 24 are arranged in sequence according to the water flow direction, the diverted water of the first diverter channel 23 can enter the second diverter channel 24 and then merge into the main channel 21.

[0043] Specifically, the flow diverter assembly 20 includes a first flow diverter sleeve 25 and a second flow diverter sleeve 26. A plurality of connecting blocks 27 are provided on the outer side of the first flow diverter sleeve 25 in the radial direction, and the plurality of connecting blocks 27 are connected to the frame 10. The first flow diverter channel 23 is formed on the outer side of the peripheral wall of the first flow diverter sleeve 25, that is, there is a gap between the radial outer side of the first flow diverter sleeve 25 (except the connecting blocks 27) and the inner side of the connecting rod 11. The radial outer side of the second flow diverter sleeve 26 is connected to the frame 10, and the radial outer side of the second flow diverter sleeve 26 (except the part connected to the connecting rod 11) can also protrude from the connecting rod 11. The second flow diverter channel 24 is formed between the outer side of the peripheral wall of the second flow diverter sleeve 26 and the inner side of the peripheral wall of the first flow diverter sleeve 25.

With this result, the diverted water of the first diverter channel 23 can flow in the radial direction, the diverted water of the second diverter channel 24 can flow in the radial direction, and the first diverter channel 23 and the second diverter channel 24 are also connected through the gap on the radial outer side.

[0044] Furthermore, in the present invention, the first diversion channel 23 and the second diversion channel 24 are arranged as inclined channels, which have a guiding effect, that is, the diversion water of the first diversion channel 23 can be guided into the second diversion channel 24, thereby achieving a better pressure reduction effect.

[0045] Specifically, the peripheral wall of the first flow diverter sleeve 25 is arranged to extend obliquely along the axial direction from the inner side in the radial direction of the first flow diverter sleeve 25 to the outer side in the radial direction of the first flow diverter sleeve 25. In the figure, the oblique extension along the axial direction specifically refers to the oblique extension toward the water outlet end of the frame 10. The peripheral wall of the second flow diverter sleeve 26 is arranged to extend obliquely along the axial direction from the inner side in the radial direction of the second flow diverter sleeve 26 to the outer side in the radial direction of the second flow diverter sleeve 26. In the figure, the oblique extension along the axial direction specifically refers to the oblique extension toward the water outlet end of the frame 10, similar to a trumpet shape.

[0046] The peripheral walls of the first flow diverter sleeve 25 and the second flow diverter sleeve 26 are set to an inclined structure, so that the radial dimensions of the first flow diverter sleeve 25 and the second flow diverter sleeve 26 gradually decrease or increase along the axial direction of the frame 10, for example, gradually increase along the water flow direction of the main channel 21 of the frame 10.

[0047] In practical applications of the present invention, the frame 10 and the flow-dividing assembly 20 are an integrally formed structure or a split structure, and are made of plastic material. The number of the flow-dividing assembly 20 in the frame 10 can be one, two, or three, etc., and can be set according to actual needs. In the figure, two flow-dividing assemblies 20 are taken as an example. The two flow-dividing assemblies 20 are spaced apart along the axial direction of the frame 10, and the main channels 21 of the two flow-dividing assemblies 20 are connected to each other.

[0048] Based on this, see Figure 7-Figure 11 The utility model also proposes a pressure regulating nozzle, including a nozzle body 30, the nozzle body 30 is provided with a water inlet 31 and a water outlet 32, and the nozzle body 30 is also provided with a cavity 33, and the cavity 33 is connected to the water inlet 31 and the water outlet 32. The above-mentioned pressure regulating component applied to the nozzle is arranged in the cavity 33. The frame 10 of the pressure regulating component is relatively fixed to the cavity 33, the main channel 21 in the frame 10 is connected to the water inlet 31 and the water outlet 32, the diversion channel 22 and the inner wall of the cavity 33 are surrounded by a diversion cavity, and the diversion cavity is connected to the main channel 21. The diversion cavity includes a first diversion channel 23 and a second diversion channel 24.

[0049] The pressure regulating nozzle of the utility model further comprises a water outlet ball head 34, a fixing cover 35 and a sealing gasket 36. The water outlet ball head 34 is installed at the water outlet 32 ​​of the nozzle body 30. The fixing cover 35 is covered on the water outlet ball head 34 and fixed to the nozzle body 30. The sealing gasket 36 is used to play a sealing role when the nozzle body 30 is installed at the water outlet of the brush ring. Fig.11 Taking the case where two flow diversion components 20 are arranged in the frame 10 as an example, the pressure regulating process of the pressure regulating nozzle of the utility model is as follows:

[0050] When water flows into the cavity 33 through the water inlet 31 and enters the first diversion component 20 in the frame 10, it is first divided into two paths by the first diversion sleeve 25. Most of the water flows into the main channel 21, and a small part of the water flows into the first diversion channel 23. When the water flows into the main channel 21 continue to flow, a small part of the water flows into the second diversion channel 24. The water flow in the first diversion channel 23 and the water flow entering the second diversion channel 24 meet and cancel each other's kinetic energy. The water flow returning from the first diversion channel 23 and the second diversion channel 24 to the main channel 21 also meets and cancels each other's kinetic energy, thereby achieving pressure reduction; thereafter, the water flow in the main channel 21 enters the second diversion component 20 of the frame 10, and the water flow is depressurized again; finally, the pressure-regulated water flow is sprayed out from the water outlet 32 ​​of the nozzle.

[0051] The pressure-reducing structure of the utility model utilizes the principle of the reverse Tesla valve to control the water pressure of the outlet water by increasing or decreasing the number of the diverter components 20, but does not affect the flow rate of the water flow. In practical applications, the number of the diverter components 20 in the nozzle body 30 and the diverter ratio of the main channel 21 to the diverter channel 22 can be designed according to the water source pressure.

[0052] See also Fig.12 , Fig.13 The utility model also provides a brush ring mechanism for a toilet, including a brush ring water outlet and the above-mentioned pressure regulating nozzle, the brush ring water outlet is formed on the pot surface of the toilet 40, and the nozzle body 30 is installed on the brush ring water outlet. When the brush ring is turned on to discharge water, water flows into the pressure regulating nozzle, is depressurized by the pressure regulating member, and finally sprayed out from the water outlet 32.

[0053] By adopting this pressure-regulating nozzle, when the water pressure flowing into the pressure-regulating nozzle is high, the pressure can be reduced through the pressure regulating component to avoid water drift and splashing that affect the user experience without affecting the flow rate; when the water pressure flowing into the pressure-regulating nozzle is low, most of the water flows directly out of the main channel 21 without affecting the flow rate, thereby ensuring the cleaning effect of the brush ring.
