[0025] like Figures 1-9 As shown, the foaming devices 100 and 100' in this embodiment are configured to be installed in the toilet and used to generate foam liquid to clean the toilet M.

[0026] like Figures 1-6 As shown, the foaming device 100 of the first embodiment of this application includes: a valve body 1, a spray head 2 and a driving device 3. The driving device 3 is used to drive the spray head 2 to rotate, so as to realize the spraying of foam liquid.

[0027] like Figures 1-3 As shown, valve body 1 is provided with a circumferential foam outlet channel A for supplying circumferentially output foam and a vertical foam outlet channel B for supplying downwardly output foam. Injector head 2 is located on valve body 1 and is provided with a circumferential injection port 21 communicating with the circumferential foam outlet channel A (see figure). Figure 1 The drive device 3 is located on the valve body 1 and is installed in conjunction with the spray head 2. It can drive the spray head 2 to rotate horizontally so that the circumferential spray nozzle 21 sprays foam in the circumferential direction. The spray nozzle 21 can spray the foam to a position in the toilet bowl cavity that is far away from the foaming device 100. In this embodiment, the drive device 3 is a drive motor.

[0028] Valve body 1 is provided with a first foaming inlet 101, a second foaming inlet 102, and a first foam outlet 103 (see reference). Figure 2) and the second foam outlet 104 (see Figure 3 The circumferential foaming channel A connects the first foaming inlet 101 and the first foaming outlet 103, and the vertical foaming channel B connects the second foaming inlet 102 and the second foaming outlet 104. Of course, there can also be one foaming inlet, which is then distributed to the two foaming outlets through the channels.

[0029] The circumferential spray nozzle 21 may include one or multiple nozzles arranged circumferentially around the spray head 2. When multiple circumferential spray nozzles 21 are included, they can be arranged in different orientations, enabling high coverage of the foam liquid in a short time. Figure 2 As shown, the plurality of circumferential injection ports 21 in this embodiment include a front injection port 211 and a rear injection port 212. Of course, left and right injection ports may also be included, which is not limited here.

[0030] The foaming device 100 of this application embodiment integrates two foaming channels: a circumferential foaming channel A and a vertical foaming channel B. The two foaming channels can produce foam simultaneously, thereby improving foaming efficiency.

[0031] like Figure 2 As shown, the valve body 1 is also provided with a first air inlet 105 communicating with the circumferential bubble outlet channel A and a second air inlet 106 communicating with the vertical bubble outlet channel B. Both the first air inlet 105 and the second air inlet 106 are configured to be connected to the air pump 4; or, one of the first air inlet 105 and the second air inlet 106 is configured to be connected to the air pump 4, and the other is configured to self-aspirate through the Venturi effect.

[0032] In the first embodiment of this application, the circumferential foam outlet channel A of the foaming device 100 uses an air pump 4 for air intake. The foam formed by the mixture of gas and liquid has a certain pressure and can be sprayed circumferentially through the circumferential spray port 21 of the spray head 2, thus covering the area of ​​the toilet bowl M that is far from the foaming device 100. The vertical foam outlet channel B realizes the second air inlet 106 through the Venturi effect, with a large air intake, which can generate enough foam to cover the toilet bowl M.

[0033] like Figure 4 As shown, the vertical foaming channel B includes an inlet channel 141, an acceleration channel 142, and a mixing outlet channel 143 connected sequentially along the water flow direction. The second air inlet 106 is connected to the acceleration channel 142. When the mixture of water and foam liquid passes through the acceleration channel 142, it can generate a Venturi effect, causing the second air inlet 106 to draw in gas.

[0034] like Figure 3As shown, the second foam outlet 104 is a vertical foam outlet pointing downwards, capable of delivering foam to the lower position of the foaming device 100. When the foaming device 100 is working, the drive device 3 drives the spray head 2 to rotate. The foam liquid generated by the circumferential foam outlet channel A is sprayed circumferentially to a farther area through the circumferential spray port 21 of the spray head 2, while the foam generated by the vertical foam outlet channel B is output downwards, covering the lower area. This allows the foam to quickly cover the toilet bowl cavity and the water surface of the toilet bowl with foam, improving foaming efficiency.

[0035] like Figure 5 As shown, the foaming device 100 also includes a first filter W1 and a second filter W2 disposed in the circumferential foam outlet channel A and the vertical foam outlet channel B. The first filter W1 and the second filter W2 can disperse and filter the foam, making the foam more uniform and delicate.

[0036] like Figure 5 As shown, the valve body 1 includes an outer shell 11 and a rotating valve core 12 disposed within the inner cavity of the outer shell 11 and connected to the drive device 3 and the injection head 2, respectively. The rotating valve core 12 and the outer shell 11 are fitted together to form a circumferential foaming channel A and a vertical foaming channel B. The drive device 3 drives the rotating valve core 12 to rotate, which in turn drives the injection head 2 to rotate. The rotating valve core 12 and the injection head 2 can be assembled separately or integrally molded.

[0037] like Figure 6 As shown, the circumferential foaming channel A includes a first transverse channel A1 and a first vertical channel A2, and the vertical foaming channel B includes a second transverse channel B1 and a second vertical channel B2. The first transverse channel A1 and the second transverse channel B1 are arranged vertically, and the first vertical channel A2 and the second vertical channel B2 are arranged to surround each other. In this embodiment, the first transverse channel A1 is displaced above the second transverse channel B1, and the second vertical channel B2 surrounds the first vertical channel A2.

[0038] like Figure 5 As shown, the rotary valve core 12 includes a valve stem 120, a first isolation disc 121 and a second isolation disc 122 disposed on the upper part of the valve stem 120 and spaced apart. Figure 2 As shown, the first isolation plate 121 isolates the drive device 3 from the circumferential foaming channel A and the vertical foaming channel B, and the second isolation plate 122 isolates the circumferential foaming channel A and the vertical foaming channel B.

[0039] like Figure 3As shown, an isolation channel C is formed between the first isolation plate 121 and the second isolation plate 122, and a connecting channel D is provided inside the valve stem 120, which connects the isolation channel C and the injection head 2. The isolation channel C and the connecting channel D form one of the first vertical channel A2 and the second vertical channel B2, and the other of the first vertical channel A2 and the second vertical channel B2 is formed between the outer wall of the valve stem 120 and the inner wall of the outer casing 11.

[0040] In this embodiment, the isolation channel C and the connecting channel D form a first vertical channel A2, and the gap E between the outer wall of the valve stem 120 and the interior of the outer casing 11 forms a second vertical channel B2. It should be noted that the formation in this embodiment may include either forming all or part of the channel.

[0041] like Figure 2 , Figure 5 As shown, the outer casing 11 has a first interface K1 and a second interface K2 on the side wall, an upper opening K3 at the upper end and a lower opening K4 at the lower end. The drive device 3 is mounted on the upper opening K3 via the mounting base 30, and the spray head 2 is arranged at the lower opening K4.

[0042] The valve body 1 also includes a first adapter 13 and a second adapter 14 that are installed in conjunction with the first interface K1 and the second interface K2. The first adapter 13 is provided with a first foam inlet 101 and a first air inlet 105, and the second adapter 14 is provided with a second foam inlet 102 and a second air inlet 106. The first adapter 13 and the second adapter 14 respectively form at least a portion of the first transverse flow channel A1 and the second transverse flow channel B1.

[0043] like Figure 6 As shown, when the foaming device 100 is working, the circumferential foaming channel A and the vertical foaming channel B respectively enter the mixed liquid (water and foaming liquid are mixed to form a mixed liquid). The circumferential foaming channel A is connected to the air pump 4 (refer to...). Figure 10 Gas is supplied and mixes with the liquid to form foam. The drive device 3 drives the spray head 2 to rotate horizontally, spraying foam liquid circumferentially through the front foam outlet 211 and rear foam outlet 212 of the circumferential foam outlet 21. The vertical foam outlet channel B achieves self-aspiration through the Venturi effect, with a large intake volume. The gas mixes with the liquid to form a large amount of foam liquid, which is then output downwards through the second foam outlet 104, covering the area below the toilet bowl M, providing a large coverage area. Simultaneous foaming in the circumferential foam outlet channel A and the vertical foam outlet channel B increases the foam volume while saving foaming time and water.

[0044] like Figures 7-10As shown, this application provides a foaming device 100' of a second embodiment. The main difference between the foaming device 100' of the second embodiment and the foaming device 100 of the first embodiment is that the circumferential foaming channel A and the vertical foaming channel B are formed in different ways. The rest can be referred to the foaming device 100 of the first embodiment, and will not be described in detail here.

[0045] In the foaming device 100', an isolation channel C is formed between the first isolation disc 121 and the second isolation disc 122 of the rotating valve core 12 of the valve body 1. The valve stem 120 has a connecting channel D that communicates with the isolation channel C. The isolation channel C and the connecting channel D form a second vertical channel B2. The gap E between the outer wall of the valve stem 120 and the interior of the outer casing 11 forms a first vertical channel A2. The injection head 2 has a circumferential injection port 21 that communicates with the first foam outlet 103 of the circumferential foaming channel A, and a vertical injection port 22 that communicates with the second foam outlet 104 of the vertical foaming channel B. In this embodiment, the second transverse channel B1 is located above the first transverse channel A1, and the first vertical channel A2 surrounds the second vertical channel B2.

[0046] like Figure 9 As shown, when the foaming device 100' is working, the circumferential foaming channel A and the vertical foaming channel B respectively enter the mixed liquid. The circumferential foaming channel A is supplied with gas by the air pump 4, which mixes with the mixed liquid to form foam. The driving device 3 drives the spray head 2 to rotate horizontally, spraying foam liquid circumferentially through the front foam outlet 211 and the rear foam outlet 212 of the circumferential foam outlet 21 of the spray head 2. The vertical foaming channel B achieves self-aspiration through the Venturi effect, where the gas mixes with the mixed liquid to form foam liquid, and the foam is output downwards through the vertical spray outlet 22 of the second foam outlet 104.

[0047] like Figure 10 As shown in the illustration, this application also provides a foaming assembly 200, including: a storage box 5, a foaming device 100 as described in any of the above embodiments connected to the output end of the storage box 5, an air pump 4 connected to the first air inlet 105 of the foaming device 100, and a water inlet valve 6 connected to the storage box 5. The water inlet valve 6 is used to input water into the storage box 5, which is used to form a mixture of foam liquid and water. The water outlet of the storage box 5 outputs through a single water pipe and is split into two paths through a three-way adapter 7, which are respectively input into the circumferential foaming channel A and the vertical foaming channel B.

[0048] like Figure 11 , Figure 12 As shown in the figure, this application embodiment also provides a toilet M, including: a toilet body 8, and a foaming component 200 as described in any of the above embodiments disposed on the toilet body 8.

[0049] The foaming assembly 200 is installed on the back seat of the toilet M, and the foaming device 100 extends into the basin cavity of the toilet M. During operation, the drive device 3 drives the spray head 2 to rotate 360° to produce foam. The circumferential spray nozzle 21 of the spray head 2 rotates 180° at a constant speed from its initial position. The foam particles sprayed from the front spray nozzle 211 cover most of the toilet bowl surface, while the foam particles sprayed from the rear spray nozzle 212 cover a smaller area of ​​the toilet bowl surface. Both the front and rear spray nozzles can cover the entire toilet bowl surface 360°.
