Description

Technical Field

[0001] The utility model generally relates to the technical field of bathroom equipment, and in particular to a foaming device. Background Art

[0002] Because there is a water seal at the bottom of the toilet, the dirty water in the water seal is easy to splash when using the toilet. By covering the surface of the toilet water seal with a layer of fine foam to form a foam shield, the splashing can be effectively suppressed. At the same time, the foam also has the effect of sterilization and odor isolation, and can also act as a lubricant, making it easier to discharge dirt.

[0003] To ensure the foam produced by the Foam Shield is sufficiently fine, a grid-structured foaming filter is typically installed within the device. If the water used to dilute the foaming agent and generate the foam contains impurities or is hard and has scale deposits, these impurities can clog the foaming filter, affecting the foaming effect or even rendering the foaming function ineffective.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0036] The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention can be practiced without one or more of the specific details, or other methods, components, materials, etc. may be employed. In other cases, well-known structures, materials or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0037] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0038] like Figure 1 As shown, this embodiment provides a foaming device, including a mixing chamber 11, which is connected to a liquid inlet channel 12 and a foam outlet channel 13, respectively. A foaming mechanism 14 is provided between the mixing chamber 11 and the foam outlet channel 13, and a diversion port 111 is provided for connecting the mixing chamber 11 with the foam outlet channel 13 and / or a toilet bowl. Of course, in other embodiments, the mixed liquid can also form foam after being impacted and dispersed within the mixing chamber 11, such as by impact with the sidewalls of the mixing chamber 11, or by impact with a baffle provided within the mixing chamber 11, and further impacted and refined by the foaming mechanism 14. Preferably, a diversion port 111 is provided between the mixing chamber 11 and the foaming mechanism 14 for connecting with the foam outlet channel 13 and / or the toilet bowl. It will be understood that in this embodiment, the liquid inlet channel 12 is connected to the liquid outlet of the foam shield dilution chamber (not shown). When the foam shield is in operation, water and the foaming agent concentrate are fully mixed and diluted in the dilution chamber (not shown) to form a mixed liquid. The mixed liquid is discharged from the liquid outlet and then enters the foaming nozzle assembly through the liquid inlet channel 12, and then forms foam through the foaming mechanism 14. When the smoothness of the foaming mechanism 14 decreases, the foam generated by the impact will follow the water flow from the guide port 111 into the foaming channel 13 and then be discharged into the toilet water seal or directly into the toilet water seal, thereby preventing the foam shield from completely failing.

[0039] like Figure 2 As shown, in one preferred embodiment, the mixing chamber 11 is further connected to an air supply channel 16, which is directly connected to the outside atmosphere or connected to an air pump. It will be understood that in this embodiment, the foaming mechanism 14 supplies air to the mixing chamber 11 through the air supply channel 16. Specifically, this can be achieved by suctioning air through negative pressure, or by directly injecting air through an air pump, mixing it with the water flow and generating more foam through the flow impact.

[0040] like Figure 2 and 3As shown, in one preferred embodiment, the side wall of the mixing chamber 11 is provided with the diversion port 111. In other embodiments, the diversion port 111 may also be provided on the foaming mechanism 14, or the diversion port 111 may be provided between the side wall of the mixing chamber 11 and the foaming mechanism 14. The diversion port 111 is connected to the foaming channel 13 and / or the toilet bowl via a diversion channel 17. It is understood that in this embodiment, the formation of the diversion channel 17 can conduct water flow more centrally. At the same time, the diversion channel 17 is preferably L-shaped, which has a simple structure and is easy to integrate.

[0041] like Figure 4 As shown, in one preferred embodiment, the foaming mechanism 14 includes a bubble filter 141, the bubble filter 141 includes a plurality of grid holes, and the diameter of the diversion port 111 is larger than the diameter of the grid holes. There are multiple bubble filters 141, and also include a spacer ring 142 between each bubble filter 141. It can be understood that in this embodiment, there are two bubble filters 141, and the spacer ring 142 is set between the two bubble filters 141. The diameter of the diversion port 111 is larger than the diameter of the grid holes. Therefore, when the grid holes of the bubble filter 141 are blocked, the foam can flow out of the diversion port 111 without affecting the use.

[0042] like Figure 5 and 6 As shown, in one preferred embodiment, an acceleration hole 112 is provided at the connection between the liquid inlet channel 12 and the mixing chamber 11. It will be appreciated that in this embodiment, the mixed liquid is ejected into a high-speed water stream after passing through the acceleration hole 112, generating a Venturi effect within the mixing chamber 11, creating a negative pressure that draws air in through the air supply channel 16. When the high-speed water stream passes through the bubble filter 141, it mixes with the drawn-in air to produce a large amount of foam, which is then discharged from the bubble outlet channel 13 to the toilet water seal, forming a foam shield.

[0043] like Figure 4 As shown, one preferred embodiment includes a switching valve assembly 200 and a foaming nozzle assembly 100 connected to the switching valve assembly 200. The foaming nozzle assembly 100 is provided with a liquid inlet channel 12, a mixing chamber 11, an air supply channel 16, and a foaming mechanism 14. It will be understood that in this embodiment, the main foaming function of the foaming device is integrated into a separate foaming nozzle assembly 100, which is connected to the switching valve assembly 200 to expand its functions. The structural separation also facilitates production and manufacturing.

[0044] A specific implementation of the present utility model is as follows.

[0045] like Figure 1 As shown, a foaming device includes a switching valve group 200 and a foaming nozzle assembly 100 and a brush ring nozzle assembly 300 connected thereto.

[0046] like Figure 1 and 6 As shown, the brush ring nozzle assembly 300 is provided with a bubble outlet channel 13 and a brush ring channel 301. The brush ring channel 301 is connected to the switching valve assembly 200, which is connected to the water supply channel and the main flushing channel 201. The switching valve assembly 200 is provided with an interface, which has an outer edge 202. The outer edge 202 is fastened with a clamp fastener 203 for threaded connection to the brush ring nozzle assembly 300.

[0047] like Figure 2 and 4 As shown, the foaming nozzle assembly 100 is provided with a mixing chamber 11, which is connected to the liquid inlet channel 12 and the air supply channel 16. An acceleration hole 112 is provided at the connection point between the liquid inlet channel 12 and the mixing chamber 11. The switching valve group 200 is provided with a socket 205, and the peripheral wall of the socket 205 is provided with a snap-fit hole 206. The foaming nozzle assembly 100 is provided with a protrusion 101 that cooperates with the snap-fit hole 206. The foaming nozzle assembly 100 is inserted into the socket 205. The foaming nozzle assembly 100 in the socket 205 is provided with an annular groove, and a sealing ring 102 is provided in the annular groove. A step portion is provided at the bottom of the socket 205. A foaming mechanism 14 is provided between the bottom of the foaming nozzle assembly 100 and the step portion, which is composed of two foaming filters 141 and a spacer ring 142. The bottom of the foaming mechanism 14 is connected to the bubble outlet channel 13 provided in the brush ring nozzle assembly 300. A guide port 111 is provided on the inner wall of the foaming nozzle assembly 100 above the foaming mechanism 14 . The guide port 111 and the foaming channel 13 are connected to each other to form an L-shaped guide channel 17 .

[0048] In other embodiments, reference Figure 7-Figure 9 A bubble rack 400 may be provided in the guide channel 17 , and the bubble rack 400 is provided with a plurality of bubble openings 401 facing the guide port 111 and the bubble outlet channel 13 . The diameter of the bubble opening 401 is relatively large and is not easily completely blocked.

[0049] In other embodiments, reference Figure 10 The bubble filter 141 can be tilted. When the bubble filter 141 is blocked, the tilted bubble filter 141 and the sidewalls of the mixing chamber 11 form a water reservoir 143. The high-speed mixed liquid impacting the water reservoir 143 can also produce foam, further preventing the problem of the bubble filter 141 being blocked and affecting the use of the foam shield. At the same time, the high-speed mixed liquid hitting the tilted bubble filter 141 can be rebounded and hit the sidewalls of the mixing chamber 11 again, facilitating the generation of foam. The generated foam shield is then discharged through the diversion channel 17. Similarly, a bubble rack 400 can also be provided within the diversion channel 17 to further generate foam.

[0050] In other embodiments, reference Figure 11The bubble filter 141 can be tilted. When the bubble filter 141 is blocked, the high-speed mixed liquid hits the tilted bubble filter 141 and can quickly turn to the bubble rack 400 for spraying, generating foam at the bubble rack 400. Of course, the bubble rack 400 can also be omitted. After the high-speed mixed liquid hits the tilted bubble filter 141, it quickly turns to the guide channel 17 and hits the side wall of the guide channel 17, thereby generating foam.

[0051] How it works

[0052] In the present invention, one end of the mixing chamber 11 is connected to the outside atmosphere through the air supply channel 16, and the other end is connected to the bubble outlet channel 13 through the bubble filter 141. The inlet of the diversion channel 17 is connected to the mixing chamber 11, and the outlet is connected to the bubble outlet channel 13 and / or the toilet bowl.

[0053] During normal operation, the foam shield thoroughly mixes and dilutes water and the original foaming agent solution within the foam shield dilution chamber (not shown) to form a mixed liquid. This mixed liquid is then discharged from the liquid outlet (not shown) and then enters the foaming nozzle assembly through the liquid inlet channel 12. After passing through the acceleration holes 112, the mixed liquid is ejected as a high-speed stream. This creates a Venturi effect within the mixing chamber 11, generating negative pressure and drawing air in through the air supply channel 16. The high-speed water flows through the foaming filter 141, mixing with the drawn-in air to produce a large amount of foam. The foam is then discharged from the foaming channel 13 to the toilet water seal, forming the foam shield.

[0054] During the foaming process, a small amount of foam in the foaming channel 13 will return to the mixing chamber 11 through the diversion channel 17. However, under the action of high-speed water flow and negative pressure, this small amount of foam can be pushed back to the foaming filter 141 and the foaming channel 13, thereby ensuring that the diversion channel 17 has no effect on normal foaming.

[0055] When the water supplied to the foam shield device contains impurities or is hard and scale-precipitated, these foreign objects can easily clog the bubble filter 141. In this case, the high-speed water entering the mixing chamber 11 cannot pass through the bubble filter 141. However, after striking the bubble filter 141, it can be diverted to the diversion channel 17 and then enter the bubble outlet channel 13 to be discharged toward the toilet water seal or directly into the toilet water seal, thereby preventing the water from being ejected from the air supply channel 16. Water does not accumulate in the mixing chamber 11, and negative pressure can still be generated within the mixing chamber 11 to draw air from the air supply channel 16.

[0056] The high-speed water flow entering the mixing chamber 11 will be broken up and mixed with the air sucked in by the negative pressure after hitting the blocked foaming filter 141. At the same time, the high-speed water flow that continues to enter the mixing chamber 11 will also continue to impact the mixed liquid to form foam. The generated foam is also discharged into the bubble outlet channel 13 through the diversion channel 17 and then discharged into the toilet water seal, or directly discharged into the toilet water seal after passing through the diversion channel 17, thereby ensuring that the foam shield function will not fail.
