Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and more particularly to a foam generating device and a toilet. Background Technology

[0002] Because of the water seal at the bottom of the toilet, dirty water inside the seal can easily splash up during use, leading to a poor user experience and posing certain hygiene problems. A foam shield generates a large amount of foam that floats on the surface of the toilet's water seal, effectively suppressing water splashing and acting as a lubricant to facilitate the removal of waste. Furthermore, the foam forms a protective layer on the toilet's water seal, locking in odors and maintaining fresh air.

[0003] Traditional foam shield devices typically use a method where water is injected into a container filled with foaming solution, forcing the solution into the foaming structure to create foam. The design of the various storage containers and foaming structures makes these devices complex and bulky, occupying significant toilet space and impacting the layout of other toilet components. Furthermore, as the amount of water injected increases, the solution in the container is continuously diluted, eventually causing the foam shield to malfunction.

[0004] Therefore, there is an urgent need for a foam generating device and a toilet to solve the above problems. Summary of the Invention

[0017] Optionally, the dispensing component includes a housing, an internal dispensing channel, a feeding end and a dispensing end, and a dispensing port at the dispensing end of the housing. The dispensing port faces the toilet bowl and is connected to the toilet bowl.

[0046] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] Figure 1 A cross-sectional view of the foam generating apparatus provided in an embodiment of the present invention is shown; Figure 2 An exploded view of the foam generating device provided in an embodiment of the present invention is shown, with reference to Figure 1 and Figure 2 This embodiment provides a foam generating device and a toilet. The toilet includes a toilet body 100, a toilet bowl, and the foam generating device provided in this embodiment. The toilet body 100 has a toilet bowl formed inside, and the toilet body 100 also has an installation space 110 in which the foam generating device is disposed. The foam generating device can communicate with the toilet bowl to generate foam on the water seal surface of the toilet bowl, thereby effectively suppressing water splashing and also acting as a lubricant to make it easier to discharge waste.

[0048] like Figure 1 As shown, the foam generating device includes a dispensing component 1, which dispenses a preset amount of granular foaming agent into the toilet bowl. The granular foaming agent comes into contact with the water seal in the toilet bowl to generate foam. In other words, this foam generating device produces foam on the water seal of the toilet bowl by quantitatively dispensing granular foaming agent, achieving the same effect as a traditional foam shield. The dispensing of the granular foaming agent is convenient, requires no storage containers, has a relatively simple structure, and occupies little space. Furthermore, the quantitative dispensing of the granular foaming agent prevents foam failure due to dilution, resulting in a better user experience.

[0049] In this embodiment, the particulate foaming agent is a particulate matter that can come into contact with water to react and produce foam, such as foaming powder.

[0050] Continue to refer to Figure 1 and Figure 2The dispensing assembly 1 includes a housing 11 and a conveying screw 12. A dispensing channel 111 is formed inside the housing 11, having an loading end 112 and a discharging end 113. A dispensing port 114 is opened at the discharging end 113, facing and communicating with the toilet bowl. The conveying screw 12 is positioned within the dispensing channel 111 along the direction from the loading end 112 to the discharging end 113, and is capable of rotating around its own axis. As the conveying screw 12 rotates, granular foaming agent is conveyed from the loading end 112 to the discharging end 113 through the screw thread, and then dispensed into the toilet bowl through the dispensing port 114. By changing the geometric dimensions of the conveying screw 12, such as the screw diameter and pitch, the dispensing amount per revolution of the conveying screw 12 can be controlled, thereby achieving precise quantitative dispensing of the granular foaming agent.

[0051] Specifically, the discharge end 113 of the dispensing channel 111 is provided with a guide ramp 115. The guide ramp 115 is formed on the bottom wall of the discharge end 113, and the distance between the guide ramp 115 and the upper surface of the water seal in the toilet bowl gradually decreases along the direction close to the dispensing port 114. The granular foaming agent conveyed to the discharge end 113 by the conveying screw 12 can flow through the guide ramp 115 to the dispensing port 114 under the action of gravity, and then flow into the toilet bowl.

[0052] Furthermore, a first cover plate 17 is rotatably connected to the dispensing port 114. The first cover plate 17 can rotate to open the dispensing port 114 and can also rotate to close the dispensing port 114. The first cover plate 17 can ensure the dryness of the granular foaming agent in the dispensing channel 111, and prevent the granular foaming agent from getting damp due to moisture in the toilet bowl, or prevent water droplets splashing when flushing the toilet bowl from entering the dispensing port 114 and contaminating the granular foaming agent inside.

[0053] More specifically, the dispensing assembly 1 also includes a storage box 14, which contains the granular foaming agent to be dispensed. The storage box 14 is located on the side of the housing 11 and communicates with the feeding end 112 of the dispensing channel 111. The end of the conveying screw 12 extends into the storage box 14, and when the conveying screw 12 rotates, the granular foaming agent in the storage box 14 can be conveyed to the dispensing port 114 by the conveying screw 12.

[0054] Preferably, the housing 11 and the storage box 14 are integrally formed to improve the overall structural integrity and effectively prevent gaps at the connection between the housing 11 and the storage box 14, which could cause leakage or moisture damage to the granular foaming agent inside the storage box 14. The housing 11 is mated to the bottom of the storage box 14 so that the granular foaming agent inside the storage box 14 falls downward under gravity and is then conveyed by the conveying screw 12.

[0055] More specifically, the dispensing assembly 1 also includes a drive component 13. The fixed end of the drive component 13 is disposed in the installation space 110, and the output end of the drive component 13 is connected to the conveying screw 12 for transmission. The drive component 13 can drive the conveying screw 12 to rotate around its own axis. The dispensing speed is controlled by controlling the rotational speed of the conveying screw 12 through the drive component 13, and the dispensing weight is controlled by different numbers of rotations, achieving uniform and quantitative dispensing. For example, the drive component 13 is selected as a motor.

[0056] In this embodiment, a single conveying screw 12 is provided. The dispensing assembly 1 also includes a connecting frame 16 and a coupling 15. The connecting frame 16 is installed within the installation space 110 and supports the coupling 15, which is rotatably mounted on the connecting frame 16. The coupling 15 connects the output end of the drive component 13 and the conveying screw 12 to achieve a transmission connection between them. The coupling 15 has advantages such as high reliability, wide applicability, and long service life.

[0057] In other embodiments, multiple conveying screws 12 may be provided, such as two or three. Multiple conveying screws 12 are arranged side-by-side, and a single drive unit 13 drives them to rotate synchronously via gear transmission or other transmission components, thereby dispensing the granular foaming agent. The arrangement of multiple conveying screws 12 helps improve the dispensing efficiency and speed of the granular foaming agent, facilitating rapid foam generation in the toilet bowl of the toilet body 100 and enhancing the user experience.

[0058] Optionally, such as Figures 1-3 and Figure 5 As shown, the foam generating device also includes an air supply assembly 2. The air supply assembly 2 includes a blower 21, which generates airflow. The air outlet 211 of the blower 21 can be selectively connected to the discharge end 113 of the dispensing channel 111 or the toilet bowl. When the air outlet 211 of the blower 21 is connected to the discharge end 113 of the dispensing channel 111, the airflow generated by the blower 21 can blow the granular foaming agent from the discharge end 113 into the toilet bowl, achieving both rapid dispensing of the granular foaming agent and reducing material residue at the discharge end 113. When the air outlet 211 of the blower 21 is connected to the toilet bowl, the airflow generated by the blower 21 can be directed into the toilet bowl for purposes such as drying the toilet bowl or the user's body.

[0059] Specifically, the air supply assembly 2 also includes a cover 22. The cover 22 is disposed adjacent to the housing 11, and an air duct 221 is formed inside the cover 22. The air outlet 211 of the fan 21 is connected to the air duct 221, and the air outlet of the air duct 221 is connected to the toilet bowl. In this embodiment, the fan 21 is disposed inside the cover 22, and the cover 22 has an opening corresponding to the air inlet of the fan 21 to facilitate air intake of the fan 21; the air outlet 211 of the fan 21 is directly connected to the air duct 221 inside the cover 22 to facilitate air supply.

[0060] Reference Figure 3 and Figure 5 The foam generating device also includes an air regulating component 3. The air regulating component 3 is connected between the cover 22 and the housing 11. The air regulating component 3 has a first state where it disconnects the air duct 221 from the discharge end 113 of the dispensing channel 111, and a second state where it connects the air duct 221 and the discharge end 113. Through the air regulating component 3, the airflow generated by the blower 21 can be connected to either the discharge end 113 of the dispensing channel 111 or the toilet bowl, to adapt to different working conditions.

[0061] Specifically, the air conditioning assembly 3 includes a mounting base 31 and an adapter 32. The mounting base 31 is disposed on the cover 22, and its interior is hollow, forming a mounting cavity 311. An adapter pipe 33 is provided on one side of the mounting base 31, connecting the mounting cavity 311 and the discharge end 113. The mounting base 31 also has a vent 312 penetrating the inner wall of the mounting cavity 311 and the wall of the cover 22. The adapter 32 is rotatably disposed within the mounting cavity 311. The adapter 32 can rotate to block the vent 312, allowing the air conditioning assembly 3 to switch between a first state and a second state. During normal airflow, the adapter 32 rotates to close the vent 312, and the air conditioning assembly 3 operates in the first state. The airflow from the air outlet 211 of the fan 21 flows along the air duct 221 into the toilet bowl, such as... Figure 3 and Figure 4 As shown, the toilet is currently in blower mode. When the foam shield function is activated, the drive component 13 drives the conveying screw 12 to rotate via the coupling 15, conveying the granular foaming agent in the storage box 14 to the dispensing port 114. Simultaneously, the adapter 32 rotates to open the vent 312, and the air regulating component 3 enters the second state. The airflow from the blower 21's air outlet 211 flows sequentially through the air duct 221, the vent 312, the mounting cavity 311, and the adapter pipe 33, flowing towards the discharge end 113 of the dispensing channel 111, and blowing open the first cover 17 to blow out the granular foaming agent, such as... Figure 5 and Figure 6 As shown, the toilet is in foam shield mode at this time. It should be noted that the first cover 17 can open automatically under the pressure of airflow, or it can be controlled to open or close by a control module. The specific method is not limited in this embodiment.

[0062] More specifically, a second cover plate 24 is rotatably installed at the air outlet of the air duct 221. The second cover plate 24 can rotate to open the air outlet and can also rotate to close the air outlet. When the second cover plate 24 opens the air outlet, the airflow in the air duct 221 can be blown towards the toilet bowl or the user's body through the air outlet; when the second cover plate 24 closes the air outlet and the air regulating component 3 is in the second state, the airflow in the air duct 221 flows through the vent 312 to the discharge end 113 of the dispensing channel 111 to blow the granular foaming agent towards the toilet bowl.

[0063] In this embodiment, the second cover plate 24 is rotatably connected to the top wall of the air outlet. A first magnetic element 241 is provided on the second cover plate 24, and a second magnetic element 25 is correspondingly provided on the side of the cover 22 at the air outlet. The second magnetic element 25 can be magnetically connected to the first magnetic element 241. For example, the second magnetic element 25 can be an electromagnet. When the toilet is in the foam shield activation mode, the second magnetic element 25 is magnetically connected to the first magnetic element 241, causing the second cover plate 24 to tightly seal the air outlet of the air duct 221. This maximizes the airflow volume and velocity of the airflow through the air regulating component 3 to the dispensing end 113 of the dispensing channel 111, ensuring uniform dispensing of the granular foaming agent.

[0064] More specifically, the air supply assembly 2 also includes air guides 23. Multiple air guides 23 are provided, extending along the extension direction of the air duct 221 and spaced apart within the air duct 221. This arrangement guides the airflow within the air duct 221, improving the uniformity of the airflow.

[0065] Preferably, the guide member 23 is gradually tilted away from the dispensing component 1 along the direction close to the air outlet. In this way, the airflow blown out of the air duct 221 can flow away from the dispensing component 1, preventing the granular foaming agent at the feeding end 113 of the dispensing component 1 from being accidentally blown out, thereby affecting the normal use by the user.

[0066] Continue to refer to Figures 1-3 and Figure 5 The foam generating device also includes a heating component 4. The heating component 4 is connected to the dispensing component 1 and is used to heat the granular foaming agent inside the dispensing component 1. Through the heating function of the heating component 4, the granular foaming agent inside the dispensing component 1 can be heated and dried, which has the beneficial effect of preventing the granular foaming agent from getting damp and clumping.

[0067] It is understood that in some embodiments, the heating component 4 is fitted outside the housing 11 corresponding to the dispensing channel 111, and the heating component 4 can heat and dry the granular foaming agent in the dispensing channel 111 when the conveying screw 12 is conveying. In other embodiments, the heating component 41 can also be directly connected to the storage box 14 to facilitate direct heating of the granular foaming agent in the storage box 14.

[0068] In this embodiment, the heating assembly 4 includes a heating element 41. The heating element 41 is disposed within the air duct 221 and can heat the airflow in the air duct 221 to blow out a high-temperature airflow when the toilet is in blower mode, thereby improving drying efficiency. Simultaneously, since the cover 22 is adjacent to the housing 11, the heating element 41 can also exchange heat with the granular foaming agent in the dispensing channel 111 of the housing 11 during heating, thereby heating and drying the granular foaming agent. Exemplarily, the heating element 41 can be an electric heating wire or the like.

[0069] As a preferred option, refer to Figure 1 and Figure 2 To further improve the heating and drying effect of the granular foaming agent, the heating assembly 4 also includes a heat-conducting element 42. An installation port is provided on the side of the cover 22 near the housing 11. A portion of the heat-conducting element 42 is disposed within the installation port and is abutted against the heating element 41. The other portion of the heat-conducting element 42 extends towards the housing 11 and is fitted over the housing 11. The heat-conducting element 42 enables heat transfer between the heating element 41 and the housing 11, thereby conducting heat to the housing 11 when the heating element 41 is heating, facilitating the heating and drying of the granular foaming agent.

[0070] Specifically, the heat-conducting element 42 includes multiple fins 421, which are spaced apart along the length of the housing 11. By providing multiple fins 421, the uniformity of heating the particulate foaming agent in the dispensing channel 111 by the heating element 41 can be improved.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
