Description

Technical Field

[0001] This utility model relates to a sanitary ware accessory device, and more specifically to a built-in foaming device for toilets and squat toilets. Background Technology

[0002] With the continuous development and progress of science and technology, people have increasingly higher requirements for quality of life and hygiene. As the main equipment in restrooms, toilets, including seated and squat toilets, play an important role in hygiene and convenience. However, squat toilets still have some shortcomings in certain aspects, such as issues with waste disposal, odor prevention, cleaning, and disinfection, especially the unpleasant odor that can permeate the entire room when one person uses the toilet.

[0003] In recent years, some external foaming devices have appeared on the market, using foam to block odors and splashes of dirty water, with good results and a certain degree of cleaning and sterilization. However, these external foaming devices require external connection, taking up space and affecting aesthetics. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a built-in foaming device. This device is installed inside the water tank, and the foaming pipe enters from the overflow pipe in the toilet or squat toilet tank, passes through a drain valve, and exits from the edge flushing hole or jet channel. Bubbles are generated by a bubble pump and rapidly transported through the foaming pipe to the drain hole to achieve the purpose of preventing splashing and odor.

[0005] This utility model is compact and aesthetically pleasing when installed inside. It solves problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and flushing. It can quickly cover the squat toilet, and the excrement falls into the foam, preventing the odor from spreading into the air, thus achieving physical deodorization and maximizing civilized toilet use.

[0006] To achieve the above objectives, according to one aspect of the present invention, a built-in foaming device is provided, comprising a shell, a cover, a battery, a bubble pump, a sensing device, and a bubble outlet tube.

[0007] Furthermore, the foaming device is installed in the water tank of the toilet or squat toilet. The foam outlet pipe enters from the overflow pipe in the water tank of the toilet or squat toilet, passes through the drain valve, and then exits from the edge flush hole or jet water channel. The bubble pump generates bubbles, which are rapidly transported to the drain hole through the foam outlet pipe to achieve the purpose of preventing splashing and odor.

[0008] Preferably, the housing is equipped with a fixing device, and the fixing device is equipped with a detachable cable tie. The foaming device is fixed to the overflow pipe in the water tank of the toilet or squat toilet via the fixing device. The installation position is above the normal water level line of the water tank.

[0009] Furthermore, a 90-degree elbow is provided on the bubble outlet tube, which is connected to the outlet end of the bubble pump. It should be noted that the elbow can also be omitted from the bubble outlet tube; the advantage of using the elbow is to prevent the bubble outlet tube from being bent, which would affect the bubble production effect.

[0010] Furthermore, the bubble pump inlet is connected to a water inlet pipe and an surfactant inlet pipe; the water inlet pipe and the surfactant inlet pipe are connected via a tee.

[0011] Further preferably, the ratio of the inner diameter of the surfactant inlet pipe to the water inlet pipe is 1:5 to 1:2. The surfactant concentration is between 1% and 20%, which results in a low viscosity and prevents instability during foaming.

[0012] Furthermore, the battery, sensing device, and bubble pump are electrically connected. The sensing module within the sensing device can be a radar sensor, a Wi-Fi receiver, a Bluetooth receiver, a 2.4G receiver, or a 5G receiver. The radar sensor can directly detect signals and transmit the information to the control sensor module, which then operates according to a pre-set program. The Wi-Fi, Bluetooth, 2.4G, or 5G receiver module works in conjunction with a remote control.

[0013] It should be noted that the batteries can be individual lithium batteries or battery packs. The batteries can be charged inside the foaming device, i.e., via a circuit board on the foaming device. Alternatively, the batteries can be removed and charged with an external charger. The interface between the battery and the circuit board can be soldered or connected via a flexible joint, facilitating battery removal.

[0014] Furthermore, a built-in foaming device also includes an installation scenario:

[0015] ① Use a thin wire to pass through the overflow outlet of the toilet or squat toilet tank, through the drain valve, and then through the flush hole or jet channel on the edge. Then tie one end of the wire inside the tank to one end of the bubble tube, and pull the wire at the other end until the bubble tube passes through.

[0016] ② Install the foaming device inside the toilet or squat toilet tank and secure it with a detachable cable tie. The installation position should be higher than the normal water level line of the tank. Insert the active agent inlet pipe into the stock solution container and place the stock solution container inside the toilet or squat toilet tank.

[0017] ③ Check if the pipes and lines are loose.

[0018] It should be noted that the thin iron wire used in step ① should not exceed 1mm in diameter and should have a smooth surface to avoid scratching the overflow port of the water tank; the original liquid container in step ② should have a sealed cap and should be placed in a way that prevents it from tipping over.

[0019] Compared with existing technologies, this invention has the following advantages: The product is simple to use, features a built-in concealed design, saves space, and does not affect the appearance. Multiple experiments have proven that the small size of the foam outlet tube does not affect the flushing effect of toilets (both seated and squat toilets). This product is compact, easy to install, and solves problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and automatic flushing, quickly covering the toilet bowl.

[0025] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0026] See Figures 1 to 4 The product shown is a built-in foaming device. It is simple to use, with a concealed built-in design that installs inside the water tank, saving space and not affecting the appearance. The small foam outlet tube does not affect the flushing effect. This product uses a liquid-machine separation method; when the concentrate runs out, the concentrate container can be removed for refilling or replacement. This compact and easy-to-install product solves problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and automatic flushing. It uses a bubble pump to generate foam, which can quickly cover the toilet bowl.

[0027] Specifically, the product includes: a housing 11, a cover 12, a battery 13, a bubble pump 14, a sensor 15, and a bubble outlet pipe 16. Its key feature is that the foaming device 1 is installed in the water tank of the toilet bowl 2 or squat toilet 3. The bubble outlet pipe 16 enters from the overflow pipe in the water tank of the toilet bowl 2 or squat toilet 3, passes through the drain valve, and exits from the edge flushing hole or jet channel. The bubble pump 14 generates bubbles, which are rapidly transported to the drain hole via the bubble outlet pipe 16 to achieve the purpose of preventing splashing and odor.

[0028] Reference Figures 2-4 The housing 11 is provided with a fixing device 111, and the fixing device 111 is provided with a detachable cable tie. The foaming device 1 is fixed to the overflow pipe in the water tank of the toilet 2 and squat toilet 3 through the fixing device 111, and the installation position is higher than the normal water level line of the water tank.

[0029] like Figure 2 As shown, a 90-degree elbow 161 is provided on the bubble outlet tube 16, and the outlet end of the bubble pump 14 is connected to the bubble outlet tube 16. It should be noted that the elbow can also be omitted from the bubble outlet tube 16. The advantage of using the elbow is to prevent the bubble outlet tube 16 from being bent, which would affect the bubble production effect.

[0030] Furthermore, the inlet end of the bubble pump 14 is connected to the water inlet pipe 141 and the surfactant inlet pipe 142; the water inlet pipe 141 and the surfactant inlet pipe 142 are connected by a T-junction.

[0031] Preferably, the inner diameter ratio of the surfactant inlet pipe 142 to the water inlet pipe 141 is 1:5 to 1:2. The surfactant concentration is between 1% and 20%. This concentration of surfactant has low viscosity and will not cause instability during foaming. By using different pipe diameters to mix with water, the desired foaming effect can be achieved, while saving the original solution, extending the usage time, and eliminating the need for frequent addition or replacement by the user.

[0032] Furthermore, the battery 13, sensing device 15, and bubble pump 14 are electrically connected. The sensing module in sensing device 15 can be a radar sensing module, a Wi-Fi receiver module, a Bluetooth receiver module, a 2.4G receiver module, or a 5G receiver module. The radar sensing module can directly sense objects and transmit the detected information to the control sensing module, which then operates according to a pre-set program. The Wi-Fi receiver module, Bluetooth receiver module, 2.4G receiver module, or 5G receiver module is used in conjunction with a remote control.

[0033] It should be noted that battery 13 can be a single lithium battery or a battery pack. Battery 13 can be charged inside the foaming device 1, that is, charged through the circuit board on the foaming device 1. Alternatively, battery 13 can be removed and charged with an external charger. The interface between battery 13 and the circuit board can be soldered or connected by a flexible joint, facilitating the removal of battery 13.

[0034] Furthermore, a built-in foaming device also includes an installation scenario:

[0035] ① Use a thin iron wire to pass through the overflow outlet of the toilet tank 2 or squat toilet 3, through the drain valve, and then through the flush hole or jet channel on the edge. Then tie one end of the iron wire in the tank to one end of the bubble tube 16, and pull the iron wire at the other end until the bubble tube 16 passes through.

[0036] ② Install the foaming device 1 inside the water tank of the toilet 2 and squat toilet 3, and fix it with a detachable cable tie. The installation position is higher than the normal water level line of the water tank. Insert the active agent inlet pipe 142 into the original liquid container and place the original liquid container inside the water tank of the toilet 2 and squat toilet 3.

[0037] ③ Check if the pipes and lines are loose.

[0038] The working principle and beneficial effects of this utility model will be specifically illustrated below through examples. Example 1

[0039] A built-in foaming device includes an automatic mode operating scenario:

[0040] ① Install the foaming device 1 according to the above installation method;

[0041] ② Turn on the switch, the radar sensing module starts working, and the control sensing module starts working; when a person is detected, bubble pump 14 starts working for 1-20 seconds and then stops working;

[0042] ③ If the bubbles are not producing properly, check if the battery is low on power and if there is still undiluted solution in the container. Example 2

[0043] A built-in foaming device, including a remote control mode operating scenario:

[0044] ① Install the foaming device 1 according to the above installation method;

[0045] ② Turn on the switch. Use the Wi-Fi receiver module, Bluetooth receiver module, 2.4G receiver module, or 5G receiver module with the remote control. Press the automatic button, and the bubble pump 14 will start working for 1-20 seconds and then stop working. Press the manual start button, and the bubble pump 14 will start working. Press the stop button, and the bubble pump 14 will stop working.

[0046] ③ If the bubbles are not producing properly, check if the battery is low on power and if there is still undiluted solution in the container.

[0047] It should be noted that the thin iron wire used in step ① should not exceed 1mm in diameter and should have a smooth surface to avoid scratching the overflow port of the water tank; the concentrate container in step ② must have a sealed cap to ensure it does not tip over when placed. In addition to the foaming surfactant, the concentrate that produces bubbles can also contain antibacterial agents, pigments, and fragrance components, resulting in better cleaning, sterilization, and deodorization effects. The concentrate in the container can also be configured according to the customer's specific requirements. In the working scenario of the above embodiment, when the concentrate container is empty, there is no notification to the user; the user needs to add concentrate themselves when bubbles are not being produced. However, this foaming device 1 can also be equipped with a liquid sensor or liquid level sensor on the concentrate container. When the liquid level in the concentrate container falls below a set value, the product stops working and prompts the user that the liquid level in the concentrate container is low and needs to be replenished.

[0048] The advantages of this invention are: the product is simple to use, with a built-in hidden design that installs inside the water tank, saving space. After installation, it does not affect the use of the water tank buttons. This compact product is easy to install and solves problems related to toilet odor prevention, splash prevention, non-sticking, cleaning, sterilization, and automatic flushing. It uses a bubble pump to generate bubbles, which can quickly cover the toilet bowl. The product can be configured via a communication module, and future upgrades can unlock more functions.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
