Description

Technical Field

[0001] The invention relates to the field of sanitary ware, and in particular to a water outlet device and an intelligent toilet flushing component. Background Art

[0002] Bubble water is becoming more and more popular among consumers because it produces less water in the same water discharge time, does not cause stinging, is gentler, and has stronger water cleaning strength. However, the existing bubble water foaming methods are generally natural aspiration, adding an air pump to provide air to the water discharge end to produce bubble water, or increasing the water pump pressurization to increase the water flow rate to produce negative pressure and inhale air to generate bubble water; in most cases of naturally aspirated bubble water, water and air are separated, water and air are not fully mixed, and are greatly affected by water pressure. The water-air mixing effect is poor, so it is not gentle enough when used, and when water contacts the stain surface, the flushing strength is weak, which is not conducive to the cleaning of stains; the method of adding an air pump and a water pump is complex in structure and costly. In addition, due to different regions, the water pressure is different across the country. Some places have low water pressure, and some places have relatively high water pressure. Many bubble water structures can form a good bubble water effect at high water pressure, but the bubble water effect is poor at low water pressure. Summary of the invention

[0006] Based on technical solution one, there is also provided technical solution two. In technical solution two, the inner diameter of the air-water mixing chamber gradually decreases along the water outlet direction.

[0007] Based on Technical Solution 2, Technical Solution 3 is also provided.

[0008] Based on any one of technical solutions one to three, a technical solution four is also provided. In technical solution four, the first water channel is coaxial with the water outlet, and the number of the second water channels is at least three and they are evenly arranged along the circumference of the water outlet.

[0009] Based on technical solution four, technical solution five is also provided. In technical solution five, the water outlet is polygonal, and the number of sides of the polygon is equal to the number of second water channels; the impact position of each second water channel on the impact surface corresponds one by one to each edge of the water outlet.

[0010] Based on technical solution five, there is also a technical solution six, in which the water outlet is a regular polygon;

[0011] The impact positions of the second water channels on the impact surface correspond one-to-one to the midpoint positions of the edges of the water outlet.

[0012] Based on technical solution six, there is also provided technical solution seven, in which the water outlet is circular.

[0013] Based on technical solution six or seven, technical solution eight is also provided. In technical solution eight, the water outlet device includes a shell and a rectifier; the rectifier is installed in the shell and enclosed with the shell to form a bowl-shaped cavity, the bowl-shaped cavity forms the gas-water mixing cavity, the bowl wall and the bowl bottom are formed on the shell, the water outlet is opened on the shell, and the end face of the rectifier facing the water outlet forms the end face of the bowl mouth of the bowl-shaped cavity; the first water channel and the second water channel are formed on the rectifier, and the water outlet ends of the first water channel and the second water channel form the water inlet ends of the gas-water mixing cavity.

[0014] Based on Technical Solution Eight, there is also provided Technical Solution Nine, in which the extension direction of the second water channel is parallel to the extension direction of the first water channel; and the water flow area of ​​the second water channel is smaller than the water flow area of ​​the first water channel.

[0015] Technical solution ten, a smart toilet flushing component, the water outlet end of the flushing component is equipped with a water outlet device described in any one of technical solutions one to nine.

[0016] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In technical solution 1, the water flow is accelerated in the first water channel and the second water channel. Since the water outlet direction of the first water channel is toward the water outlet and the water flow area of ​​the port of the first water channel connected to the air-water mixing chamber is smaller than the water flow area of ​​the water outlet, the water flow of the first water channel can directly flow out of the water outlet without interference, and the water flow of the second water channel collides with the impact surface of the air-water mixing chamber, causing the water flow of the second water channel to be blocked and collided, that is, the water flow of the second water channel is limited, so the water flow is mainly concentrated to flow out through the first water channel, and the water pressure is also concentrated on the water flow of the first water channel. The water flow velocity of the first water channel is faster and forms a negative pressure in the air-water mixing chamber to inhale a large amount of air from the water outlet. Part of the water flow of the second water channel breaks to form granular water that is fully mixed with the air, and part of it flows back to wrap the air inside, thereby in the air-water mixing chamber. The bubble water formed inside is mixed with air with a high air content. The mixed water flow gathers around the water flow in the first water channel and flows out of the water outlet with the water flow in the first water channel, forming super soft bubble water and producing a large water column effect. In the present technical solution, since the water pressure is concentrated on the water flow in the first water channel, when the water pressure is low, the flow rate of the water flow in the first water channel is also faster, thereby producing a good air suction effect. The setting of the impact surface further enables the water flow and the air to be fully mixed, so that the formed bubble water has a high air content, is non-stirring and softer when used, and has a good stain flushing effect. In addition, the present technical solution also creatively arranges the air-water mixing chamber upstream of the atmosphere inlet, and the air enters the air-water mixing chamber against the water outlet direction, and there is no need to separately set an air intake channel for feeding air. The structure is ingenious and simpler.

[0018] 2. In the second technical solution, the inner diameter of the air-water mixing chamber gradually decreases along the water outlet direction, which is convenient for forming an impact surface, has good breaking and diversion effects, and has a simple structure and is easy to implement.

[0019] 3. In technical solution three, since the directions of the broken granular water are different, the water flow is relatively turbulent, and the impact surface is located on the bowl wall of the bowl-shaped cavity, that is, the impact surface is an arc-shaped surface, so that most of the water flow flows back, and only a small part of the water flow collides to form granular water, thereby avoiding excessive turbulence of the water flow in the air-water mixing chamber, and the backflowing water flow can cover a large amount of air. The bubble water formed by the backflow-covered air has a higher air content than the bubble water formed by the mixture of granular water and air, and is therefore softer, more comfortable to use without a tingling sensation, and has a better cleaning effect.

[0020] 4. In technical solution 4, the number of second water channels is at least three and they are evenly arranged along the circumference of the water outlet, so that the water flow of the second water channel flows out around the water flow of the first water channel, which is convenient for forming a large water column effect when the water pressure is low, and is more beautiful.

[0021] 5. In technical solution five, the water outlet is polygonal, and the impact positions of each second water channel on the impact surface correspond to each edge of the water outlet one by one. When the water flow of the second water channel flows out of the water outlet, the water flows of the two adjacent second water channels will collide and gather at the outer corners of the polygon. Since the water flow velocity of the first water channel is fast, the water flow of the first water channel will absorb the water flow gathered at the outer corner after flowing out of the water outlet, thereby forming sheet water. The outflowing water flow converges into a beam after moving away from the water outlet, thereby forming multiple sheets of sheet water surrounding the middle water column, which is more beautiful.

[0022] 6. In technical solution six, the water outlet is a regular polygon, and the impact positions of each second water channel on the impact surface correspond to the midpoint positions of each side of the water outlet one by one, so that the sheet water formed corresponding to each corner of the water outlet is more consistent. Since the first water channel is coaxial with the water outlet, the splashes formed by the water flowing out of the water outlet are more symmetrical and more beautiful.

[0023] 7. In technical solution seven, the water outlet is circular. When water is discharged, the water flow of the second water channel collides with the arc-shaped impact surface to form backflow water and wraps the water flow of the first water channel in the middle to gather to form a large volume of water. Under the strong pressure of the water flow in the first water channel, it flows out to form large-particle water. After the water flows out of the water outlet, the water volume in the air-water mixing chamber is reduced in an instant. When the water flows out again, a gap is formed between the water flow and the previous outflow, thereby forming an obvious large-particle water effect with a good visual effect.

[0024] 8. In technical solution eight, the structure of the water outlet device is simple and practical.

[0025] 9. In technical solution nine, the extension direction of the second water channel is parallel to the extension direction of the first water channel, which is convenient for maintaining the consistency of the water outlet directions of the first water outlet and the second water outlet, and is convenient for the processing of the rectifier with low cost; the water flow area of ​​the second water channel is smaller than the water flow area of ​​the first water channel, which further concentrates the water pressure in the first water channel, making it easier to form ultra-soft bubble water under low pressure.

[0026] 10. In technical solution 10, the smart toilet flushing part of the present invention includes the above-mentioned water outlet device, and the bubble water formed has a high air content, is softer, has a good flushing effect, and has an ingenious and simple structure, low cost, and good user experience.

[0044] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0045] See also Figure 1-9 , Figure 1-9 A water outlet device is shown, which includes a housing 100 and a rectifier 200 .

[0046] The housing 100 includes a water inlet body 10 and a water outlet body 20 which are fixed to each other. In this embodiment, the water inlet body 10 is sealed and inserted into the water outlet body 20 .

[0047] like Figure 2-3 The water outlet body 20 is a cylindrical structure with an opening downward, and a first step hole is provided therein, wherein the small hole of the first step hole forms a water outlet cavity 21, the large hole of the first step hole forms a receiving cavity 22, and the hole shoulder of the first step hole forms the cavity bottom of the receiving cavity 22, that is, the receiving cavity 22 and the water outlet cavity 21 are connected. Figure 3 As shown, the water outlet chamber 21 is located above the accommodating chamber 22, the bottom of the cylinder forms the bottom of the water outlet chamber 21, the bottom of the water outlet chamber 21 is provided with a water outlet 211, the inner diameter of the upper water outlet chamber 21 gradually decreases in the direction approaching the water outlet 211, and the cavity wall of the water outlet chamber 21 close to the water outlet 211 is arc-shaped, i.e., an arc-shaped cavity wall 212 is formed.

[0048] like Figure 2-3 As shown, the water inlet body 10 is composed of a left water inlet part 11 and a right water inlet part 12 fixedly connected to each other. The left water inlet part 11 is a cylindrical structure with an opening upward, and a second step hole is provided therein. The large hole of the second step hole forms a mounting cavity 111, and the small hole of the second step hole forms a water inlet cavity 112. The hole shoulder of the second step hole forms the cavity bottom of the mounting cavity 111 so that the water inlet cavity 112 and the mounting cavity 111 are connected. The right water inlet part 12 is tubular and has a through hole axially provided therein to form a water inlet channel 121. The side wall of the through hole in the small hole of the second step hole is connected to the small hole of the second step hole so that the water inlet channel 121 is connected to the water inlet cavity 112. In this embodiment, the outer diameter of the left water inlet part 11 is adapted to the inner diameter of the large hole of the first step hole so that the left water inlet part 11 can be inserted into the accommodating cavity 22.

[0049] Still refer to Figure 2-3 The rectifier 200 is cylindrical, and a flange 201 is protruded from the outer wall of the lower end thereof, and a first hole 202 is formed in the center thereof, and at least two second holes 203 are formed around the first hole 202. The second holes 203 are evenly distributed along the circumferential direction. The second holes 203 are smaller than the first holes 202. The area of ​​the first hole 202 is smaller than the area of ​​the water outlet 211. In this embodiment, there are three second holes 203. However, it should be understood that the number of second holes 203 can be opened as needed. It can be seen that the rectifier 200 has a simple structure, is easy to process, and has low cost.

[0050] In this embodiment, the outer diameter of the flange 201 of the rectifier 200 is matched with the inner diameter of the large hole of the second step hole so that the flange 201 can be inserted into the installation cavity 111 and the flange 201 abuts against the shoulder of the second step hole; the outer diameter of the cylinder of the rectifier 200 is matched with the inner diameter of the lower part of the small hole of the first step hole so that the cylindrical part of the rectifier 200 can be inserted into the lower area of ​​the water outlet cavity 21, and after the rectifier 200 is inserted into the water outlet cavity 21, as shown in FIG. Figure 5 As shown, the first hole 202 faces the water outlet 211 and is coaxial with the water outlet 211 , and the second hole 203 faces the arc-shaped cavity wall 212 of the water outlet cavity 21 .

[0051] The installation process is as follows:

[0052] Insert the flange 201 of the rectifier 200 into the installation cavity 111 of the left water inlet 11 and make the lower surface of the flange 201 abut against the shoulder of the second step hole, then insert the rectifier 200 and the left water inlet 11 into the water outlet 20 together, the cylindrical part of the rectifier 200 is inserted into the lower area of ​​the water outlet cavity 21 of the water outlet 20 and enclosed with the water outlet cavity 21 to form a bowl-shaped cavity, and the left water inlet 11 is inserted into the accommodating cavity 22 of the water outlet 20, and the installation is completed. Figure 3-5As shown, at this time, the rectifier 200 is installed in the lower area of ​​the installation cavity 111 and the water outlet cavity 21, and the water inlet cavity 112 is connected to the water outlet cavity 21 through the first hole 202 and the second hole 203. In practical applications, when the water inlet body 10 and the water outlet body 20 are both made of metal materials, the left water inlet part 11 can be welded with the water outlet body 20 so that the water inlet body 10 and the water outlet body 20 are fixedly connected; when the water inlet body 10 and the water outlet body 20 are both made of plastic materials, the left water inlet part 11 and the accommodating cavity 22 are interference fit so that the water inlet body 10 and the water outlet body 20 are fixedly connected. However, it should be understood that the fixing method of the water inlet body 10 and the water outlet body 20 is not limited to this.

[0053] After the connection is completed, Figure 4-5 As shown, the water outlet device is provided with a first water channel 01 , at least two second water channels 02 and an air-water mixing chamber 03 . Specifically, the first hole 202 forms the first water channel 01, and the second hole 203 forms the second water channel 02, that is, the first water channel 01 and the second water channel 02 are formed on the rectifier 200; the rectifier 200 is installed in the shell 100 and encloses the shell 100 to form a bowl-shaped cavity, the bowl-shaped cavity forms an air-water mixing cavity 03, and the bowl wall and the bowl bottom are both formed on the water outlet body 20. In this embodiment, the arc-shaped cavity wall 212 of the water outlet cavity 21 forms the bowl wall, and the cavity bottom of the water outlet cavity 21 forms the bowl bottom, that is, the water outlet 211 is located at the bottom of the bowl of the bowl-shaped cavity; the end face of the rectifier 200 facing the water outlet 211 forms the end face of the bowl mouth of the bowl-shaped cavity, and the water outlet ends of the first water channel 01 and the second water channel 02 form the water inlet ends of the air-water mixing cavity 03, that is, the first water channel 01 and the second water channel 02 are connected to the air-water mixing cavity 03 at the bowl mouth of the air-water mixing cavity 03.

[0054] It can be seen that in this embodiment, the second water channels 02 are evenly arranged around the circumference of the first water channel 01; the water outlet direction of the second water channel 02 is parallel to the water outlet direction of the first water channel 01 to avoid the water flows of the first water channel 01 and the second water channel 02 from interfering with each other and generating turbulence; the extension direction of the second water channel 02 is parallel to the extension direction of the first water channel 01, and the water flow area of ​​the second water channel 02 is smaller than the water flow area of ​​the first water channel 01.

[0055] It can be seen that in this embodiment, the inner diameter of the air-water mixing chamber 03 gradually decreases along the water outlet direction; the air-water mixing chamber 03 connects the first water channel 01 and the second water channel 02 and is provided with a water outlet 211, the water outlet direction of the first water channel 01 is toward the water outlet 211, and the water flow area of ​​the port of the first water channel 01 connecting the air-water mixing chamber 03 is smaller than the water flow area of ​​the water outlet 211; the air-water mixing chamber 03 is provided with an impact surface 031 facing the second water channel 02 for the water flow of the second water channel 02 to impact so that the water flow of the second water channel 02 forms bubble water in the air-water mixing chamber 03. Among them, the bowl wall of the bowl-shaped cavity forms the impact surface 031.

[0056] Here’s how it works:

[0057] The water flows into the first water channel 01 and the second water channel 02 after entering the water inlet chamber 112 from the water inlet channel 121. Since the water flow area at the first water channel 01 and the second water channel 02 is reduced, the water flow is accelerated at the first water channel 01 and the second water channel 02. Since the water outlet direction of the first water channel 01 is toward the water outlet 211 and the water flow area of ​​the port of the first water channel 01 connected to the air-water mixing chamber 03 is smaller than the water flow area of ​​the water outlet 211, the water flow of the first water channel 01 can directly flow out of the water outlet 211 without interference, and the water flow of the second water channel 02 collides with the impact surface 031 of the air-water mixing chamber 03, resulting in the water flow of the second water channel 02 being blocked and collided, that is, the second The water flow in water channel 02 is restricted, so the water flow is mainly concentrated through the first water channel 01, and the water pressure is also concentrated on the water flow in the first water channel 01. The water flow in the first water channel 01 has a faster flow rate and forms a negative pressure in the air-water mixing chamber 03, sucking in a large amount of air from the water outlet 211. Part of the water flow in the second water channel 02 breaks up to form granular water that is fully mixed with the air, and part of it flows back to wrap the air, thereby forming a mixture of bubble water and air in the air-water mixing chamber 03 with a high air content. The mixed water gathers around the water flow in the first water channel 01 and flows out of the water outlet 211 along with the water flow in the first water channel 01, forming super soft bubble water and producing a large water column effect.

[0058] It can be seen that, with this technical solution, since the water pressure is concentrated on the water flow of the first water channel 01, when the water pressure is low, the flow rate of the water flow of the first water channel 01 is also fast, thus producing a good air suction effect. The setting of the impact surface 031 further allows the water flow to be fully mixed with the air, so that the bubble water formed has a high air content, is softer and has a good stain flushing effect without a stinging feeling when used; and because the water flow area of ​​the second water channel 02 is smaller than the water flow area of ​​the first water channel 01, the water pressure is further concentrated in the first water channel 01, making it easier to form ultra-soft bubble water under low pressure. In addition, this technical solution also creatively sets the air-water mixing chamber 03 upstream of the atmospheric inlet, and the air enters the air-water mixing chamber 03 against the water outlet direction, and there is no need to set up a separate air intake channel for feeding air, so the structure is ingenious and simpler.

[0059] More preferably, since the directions of the broken granular water are different, the water flow is relatively turbulent, and the impact surface 031 is located on the bowl wall of the bowl-shaped cavity, that is, the impact surface 031 is an arc-shaped surface, so that most of the water flow flows back, and only a small part of the water flow collides to form granular water, thereby avoiding that the water flow in the air-water mixing chamber 03 is too turbulent, and the backflowing water flow can cover a large amount of air inside. The bubble water formed by the backflow-covered air has a higher air content than the bubble water formed by the mixture of granular water and air, and is therefore softer and has a better cleaning effect.

[0060] Accordingly, the present invention also improves the water discharge effect. Figure 6-8, the number of the second water channels 02 is at least three; the water outlet 211 is polygonal, and the number of sides of the polygon is equal to the number of the second water channels 02; the impact position of each second water channel 02 on the impact surface 031 corresponds to each side of the water outlet 211. In this way, when the water flow of the second water channel 02 flows out of the water outlet 211, the water flows of two adjacent second water channels 02 will collide and gather at the outer corner of the polygon. Since the water flow of the first water channel 01 has a fast flow rate, the water flow of the first water channel 01 will absorb the water flow gathered at the outer corner after flowing out of the water outlet 211, thereby forming sheet water. The outflowing water flow converges into a beam after leaving the water outlet 211, thereby forming multiple sheets of sheet water surrounding the middle water column, which is more beautiful. Furthermore, the water outlet 211 is in the shape of a regular polygon. Since the first hole 202 is coaxial with the water outlet 211, that is, the first water channel 01 is coaxial with the water outlet 211, the water splash formed by the water flowing out of the water outlet 211 is further made more symmetrical and more beautiful.

[0061] More preferably, the impact position of each second water channel 02 on the impact surface 031 corresponds one-to-one to the midpoint position of each edge of the water outlet 211, so that the sheet water formed corresponding to each corner of the water outlet 211 is more consistent, and further makes the water splash formed by the water flowing out of the water outlet 211 more symmetrical and more beautiful. Figure 8-9 It shows the effect that the water outlet 211 is an equilateral triangle.

[0062] However, it should be understood that the water outlet 211 may also be in other shapes, such as a circle, and the number of the second water channels 02 is at least three, and the second water channels 02 are evenly arranged around the circumference of the water outlet 211. Figure 1-5 The water outlet 211 is circular. When water is discharged, the water flow of the second water channel 02 collides with the arc-shaped impact surface 031 to form backflow water and wraps the water flow of the first water channel 01 in the middle to gather to form a large volume of water. Under the strong pressure of the water flow of the first water channel 01, it flows out to form large-particle water. After the water flows out of the water outlet 211, the water volume in the air-water mixing chamber is reduced in an instant. When the water flows out again, a gap is formed between the water flow and the previous outflow, thereby forming an obvious large-particle water effect with a good visual effect.

[0063] The present invention also provides an intelligent toilet flushing device, such as Fig.10 As shown, one of the water outlet ends of the flushing part is equipped with the water outlet device in the above embodiment. In this way, the bubble water formed has a high air content, is gentler and has no stinging feeling when used, has a good effect of flushing stains, and has a clever and simple structure, low cost, and good user experience.

[0064] It should be understood that the water outlet device of the present invention can also be installed at the water outlet end of a shower head or a pull-out faucet.
