Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0022] like Figure 1 As shown, the brush ring nozzle device 100 of this utility model embodiment includes a brush ring water inlet 101 and a brush ring water outlet 102, as well as a connecting flow channel S (see figure) connecting the brush ring water inlet 101 and the brush ring water outlet 102. Figure 1 (The connected area is marked by a dashed line). The brush ring nozzle device 100 also includes a foaming liquid inlet 103 and a microbubble water inlet 104 connected to the connecting flow channel S. The microbubble water inlet 103 and the foaming liquid inlet 104 are respectively configured to be connected to the microbubble supply system C and the foaming liquid supply system B (see reference). Figure 5 As shown), the flow area ∅1 of the microbubble water inlet 104 is not greater than 120% of the flow area ∅2 of the foaming liquid inlet 103.

[0023] Generally, for ease of manufacturing and compatibility of the two inlets, the flow area of ​​the microbubble water inlet 104 can be designed to be equal to the flow area ∅2 of the foaming liquid inlet 103. Furthermore, to ensure the inflow velocity of the foaming liquid, the flow area of ​​the foaming liquid inlet 103 should not exceed 15 mm². 2 .

[0024] The brush ring nozzle device 100 of this utility model embodiment is additionally equipped with a foaming liquid inlet 103 and a microbubble water inlet 104. The foaming liquid inlet 103 and the microbubble water inlet 104 can introduce foamed water and microbubble water to be sprayed out together from the brush ring outlet 102 of the brush ring nozzle device 100, which is used to spray water onto the toilet M (see reference). Figure 6 The ceramic pot surface (as shown) is rinsed to achieve a deep cleaning and sterilization effect.

[0025] Because the foaming liquid inlet 103 and the microbubble water inlet 104 need to be connected to the microbubble supply system C and the foaming liquid supply system B respectively, installers may mistakenly connect them during installation, resulting in the foaming liquid supply system B being connected to the microbubble water inlet 104. However, the microbubble inlet 104 typically has a much larger flow area than the foaming liquid inlet 103. This leads to a larger single-cycle supply of foaming liquid during brush ring foaming, thus reducing the lifespan of the foaming liquid and increasing user operating costs.

[0026] Therefore, in this embodiment of the utility model, the flow area of ​​the microbubble water inlet 104 is designed to be no more than 120% of the flow area of ​​the foaming liquid inlet 103, so that the flow area ∅1 of the microbubble water inlet 104 and the flow area ∅2 of the foaming liquid inlet 103 are close, and even if the installer connects it incorrectly, it will not cause the foaming liquid to be used too quickly.

[0027] Conversely, if the microbubble supply system C is connected to the foaming liquid inlet 103, which has a small flow area, the microbubble water flow rate is reduced, resulting in a decrease in the cleaning and sterilization effect on the pot surface. To ensure that the microbubble water content does not decrease, this embodiment of the invention ensures a sufficient microbubble water flow rate by improving the supply channel of the microbubble supply system C.

[0028] In order to ensure that the brush ring water of the brush ring nozzle device 100 has a sufficient content of microbubble water, the flow area of ​​the microbubble water inlet 104 in this embodiment of the present invention is designed to be no less than 80% of the flow area of ​​the foaming liquid inlet 103, thereby ensuring that the microbubble water has a sufficient microbubble content.

[0029] like Figure 1 , Figure 2 As shown, the connecting channel S includes an inlet channel 10, an acceleration channel 11, and a mixing output channel 12 connected sequentially along the water flow direction. The foaming liquid inlet 103 is connected to the acceleration channel 11 and the mixing output channel. An air intake hole 110 is provided at the acceleration channel 11. When the water flows through the acceleration channel 11, a Venturi effect is generated, causing the air intake hole 110 to draw in gas and mix it with the foaming liquid.

[0030] The brush ring nozzle device 100 of this utility model embodiment, by setting an acceleration channel 11, can generate a Venturi effect when the water flows through the brush ring, automatically draw in air and mix the gas with the foaming liquid to generate cleaning foam, and the overall structure is simple.

[0031] like Figure 1 , Figure 3 As shown, the brush ring nozzle device 100 of this utility model embodiment includes a brush ring nozzle 2 and a foaming connector 1 connected to the water inlet end of the brush ring nozzle 2. The foaming connector 1 is provided with the aforementioned water inlet channel 10, acceleration channel 11 and mixing output channel 12 connected in sequence along the water flow direction. The foaming connector 1 is also provided with a foaming liquid conveying channel 13 and a microbubble water conveying channel 14 connected to the acceleration channel 11. The input ends of the foaming liquid conveying channel 13 and the microbubble water conveying channel 14 are respectively connected to the foaming liquid inlet 103 and the microbubble water inlet 104.

[0032] The brush ring nozzle device 100 of this utility model features a separate design for the brush ring nozzle 2 and the foaming connector 1. The foaming connector 1 can be fitted with the existing brush ring nozzle 2, eliminating the need for users to replace the entire brush ring nozzle 2 and reducing operating costs. Furthermore, the brush ring nozzle device 100 can be applied to both non-foaming and foaming usage scenarios. The brush ring nozzle 2 and the foaming connector 1 can be installed together on the toilet M without altering the structure of the toilet M, making the brush ring nozzle device 100 simple to install, highly compatible, and space-saving. Of course, the brush ring nozzle 2 and the foaming connector 1 can also be integrally molded; this is not a limitation.

[0033] like Figure 3 , Figure 4 As shown, the foaming connector 1 includes a water inlet connector 3 forming a water inlet channel 10, a foaming liquid connector 4 forming a foaming liquid conveying channel 13, and a microbubble water connector 5 forming a microbubble water conveying channel 104. The water inlet connector 3, the foaming liquid connector 4, and the microbubble water connector 5 are located on the same side of the foaming connector 1 and are arranged adjacent to each other along the water flow direction.

[0034] like Figure 1 , Figure 4 As shown, the foaming connector 1 also has an air inlet chamber 105 located at the top, and an upper cover 6 that cooperates with and covers the air inlet chamber 105. The upper cover 6 has an air inlet hole 60 that communicates with the outside, and an air intake hole 110 that communicates with the air inlet chamber 105. The water inlet connector 3, the foaming liquid connector 4, and the microbubble water connector 5 are located on the opposite side of the air inlet chamber 105.

[0035] The brush ring nozzle device 100 of this utility model reduces the complexity of the water channel arrangement of the foaming joint 1 by placing the air inlet chamber 105 on the upper part of the foaming joint 1, and placing the water inlet connector 3 and the foaming liquid connector 4 on the same side of the foaming joint 1 and on opposite sides of the foaming joint 1. This facilitates processing and manufacturing, and allows the main body of the foaming joint 1 to be manufactured in an integral molding manner.

[0036] like Figure 3 , Figure 4 As shown, the foaming connector 1 includes a sleeve end 7 forming a mixing output channel. The sleeve end 7 is fitted with the water inlet end 201 of the brush ring nozzle 2 using a snap-fit ​​structure 70, and a second sealing ring 26 is provided at the sleeve end. Figure 2 As shown, a gap channel 112 is formed between the sleeve end 7 and the side wall of the water inlet end 201, which communicates with the mixing output channel 12. The foaming liquid connector 4 and the microbubble water connector 5 are located at the sleeve end 7 and are both connected to the gap channel 112. A chamfer is provided at the port of the water inlet end 201 of the brush ring nozzle 2. An annular cavity 111 (the cross-section of the annular cavity 111 is triangular) is formed between the chamfer and the inner wall of the sleeve end 7. After the foaming liquid enters from the gap channel 112, it will first fill the annular cavity 111. The foaming liquid is mixed into the brush ring water from multiple circumferential positions, thereby achieving mixing and generating foam more quickly.

[0037] like Figure 4 As shown, the brush ring nozzle 2 includes a nozzle body 20, a pressure cap 21 detachably mounted to the water outlet end of the nozzle body 20, a universal nozzle 23 located at the water outlet end of the nozzle body 20, and a mounting base 24 for mounting the universal nozzle 23. In this embodiment of the invention, the nozzle body 20 and the pressure cap 21 are connected by threads, and the connection is sealed with a first sealing ring 25 to prevent water leakage. The brush ring nozzle 2 also includes a locking nut 22 screwed onto the outer wall of the nozzle body 20, which is used to fix the nozzle body 20 to the toilet bowl M.

[0038] like Figure 5 As shown, this utility model embodiment also provides a brush ring system 1000, including a brush ring nozzle device 100 as described in any of the above embodiments, a water supply system A, a foaming liquid supply system B, and a microbubble supply system C respectively connected to the brush ring water inlet 101, the foaming liquid inlet 103, and the microbubble water inlet 104 of the brush ring nozzle device 100.

[0039] Water supply system A includes a first water supply pump (not shown) connected to the brush ring water inlet 101. The first water supply pump can be connected to a municipal water source or to a water tank (not shown). Foaming liquid supply system B includes a foaming liquid storage device (not shown) and a liquid supply pump (not shown) connecting the foaming liquid storage device and the foaming liquid inlet 103. The liquid supply pump can be a peristaltic pump. Microbubble supply system C includes a microbubble generating device 80 and a second water supply pump (not shown) supplying water to the microbubble generating device 80. The microbubble generating device 80 is capable of generating micro / nanobubbles through gas-liquid mixing.

[0040] The microbubble supply system C also includes a heated water supply device 81. Water supplied by the second water supply pump enters the heated water supply device 81 and then enters the microbubble generating device 80. The heated water supply device 81 divides the water into two paths through a distribution valve 82. One path supplies water to the microbubble generating device 80, and the other path supplies water to the human body cleaning device 83. The heated water supply device 81 can be an instant hot water supply device.

[0041] In this embodiment of the invention, the brush ring nozzle device 100 reduces the size of the microbubble water inlet 104 to ensure compatibility with the foaming liquid supply system B even after misconnection, but this results in a reduction in the microbubble water flow rate. To maintain the overall cleaning and sterilization effect on the pot surface, the inlet flow rate of the microbubble water inlet 104 needs to be increased. In this embodiment, the duty cycle of the second water supply pump is increased to increase the inlet flow rate of the microbubble water inlet 104. To achieve a good cleaning and sterilization effect on the pot surface using ultra-microbubbles, the flow rate of microbubble water supplied by the microbubble supply system C should not be less than 5% of the inlet flow channel of the water supply system A. The flow rate control of the water supply system A and the microbubble supply system C can be achieved by selecting the models of the first and second water supply pumps or by controlling the duty cycle.

[0042] like Figure 6 As shown, this utility model embodiment also provides a toilet M, including a toilet body and a brush ring system 1000 as described in any of the above embodiments, which is installed in conjunction with the toilet body.
