Description

Technical Field

[0001] The invention relates to the technical field of kitchen and bathroom, in particular to a foam shield structure and a toilet. Background Art

[0002] The foam shield is a new toilet function. It not only has the function of blocking odor with a water seal, but also has a better appearance compared with a water seal. In addition, it will not bring the bad experience of splashing water, and is loved by consumers. The realization of the foam shield requires a certain proportion of water, foam liquid and air to be mixed, so the above three materials need to be pumped into the foam generator. Therefore, the existing foam shield structure mostly uses multiple pumps to transport water, foam liquid and air respectively. For the structure of multiple pumps, there are the following problems: 1. High cost; 2. Relatively cumbersome installation; 3. Multiple pumps work at the same time, and the noise is loud; 4. The coordination between the pumps is poor, and after long-term use, the aging speed of the pumps may be different, which will cause a large error in the discharge ratio of the material. To this end, the present invention provides a new foam shield structure that can solve the above technical problems. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a foam shield structure with low cost and stable discharge ratio.

[0004] A foam shield structure comprises a raw material cabin, a pump body and a foam shield generator.

[0005] The raw material chamber includes an independent raw liquid chamber and a mixing chamber. The raw liquid chamber is provided with a liquid outlet channel connected to the mixing chamber, so that the raw liquid can be transported to the mixing chamber through the liquid outlet channel. The mixing chamber is provided with a water inlet and a mixed liquid outlet, which are respectively used to introduce water and discharge the mixed liquid.

[0006] The gas outlet end of the pump body includes a first gas path and a second gas path, and the second gas path is provided with a flow controller. The gas outlet end of the first gas path extends into the raw liquid cavity to inflate the raw liquid cavity, and the raw liquid cavity uses air pressure to press the raw liquid inside into the mixing cavity through the liquid outlet channel. The gas outlet end and the mixed liquid outlet of the second gas path are both connected to the feed end of the foam shield generator as the foam generating material.

[0007] The foam shield structure provided by the present invention integrates the raw liquid delivery pump and the air delivery pump into one, thereby reducing the number of pumps, avoiding high costs and cumbersome installation problems, and the overall noise during operation is relatively reduced. In addition, by providing a flow controller in the second gas path, the gas flow ratio of the two gas paths can be controlled, which can not only provide gas according to demand, but also avoid the problem of insufficient air pressure provided by the first gas path and squeezing out viscous raw liquid.

[0008] Preferably, the flow controller is a replaceable flow limiting tube, which is blocked inside the second air path and provided with an air hole, thereby reducing the exhaust volume of the second air path and increasing the air pressure of the first air path. When other proportions of foam generating materials are required, replaceable flow limiting tubes with other different apertures can be selected.

[0009] Preferably, the flow controller is a control valve, which is installed inside the second gas circuit and is provided with a flow regulating switch. The user only needs to use the flow regulating switch to control the gas outlet ratio of the two gas circuits. The structure is simple and easy to control.

[0010] Preferably, the control valve is provided with a normal gear and a saving gear for the user to choose. When the normal gear is selected, the foam produced is relatively thick, and the bubble size is small and dense. When the saving gear is selected, the bubbles produced are relatively sparse, and the bubble size is larger without affecting the foam shield function, thereby saving the original liquid.

[0011] Preferably, the first gas circuit and the second gas circuit are connected to the gas outlet end of the pump body via a three-way joint, which is easy to assemble.

[0012] Preferably, the mixed liquid outlet is connected to a mixed liquid outlet pipe, and the mixed liquid outlet pipe and the second gas path are butt-jointed to the feed end of the foam shield generator via a three-way joint, which is easy to assemble.

[0013] Preferably, the liquid inlet end of the liquid outlet channel extends to the bottom of the original liquid chamber, and the liquid outlet end extends to the top of the mixing chamber, and a one-way valve is provided in the liquid outlet channel to prevent the mixed liquid from entering the original liquid chamber.

[0014] Preferably, a raw liquid injection pipe is provided at the top of the raw liquid chamber, and a one-way valve is provided in the raw liquid injection pipe to avoid the situation where the raw liquid cannot be transported to the mixing chamber due to pressure relief.

[0015] Preferably, a liquid level sensor is provided around the periphery of the original liquid chamber, which has a low liquid level alarm function to remind the user to replenish the original liquid.

[0016] Preferably, a drain port is provided at the bottom of the original liquid cavity, and a plug is provided at the drain port. By opening the plug, the original liquid in the original liquid cavity can be discharged, so as to facilitate the cleaning of the original liquid cavity.

[0017] Preferably, a water inlet pipe is provided at the top of the mixing chamber, and a one-way valve is provided in the water inlet pipe to prevent the mixed liquid from polluting the water source.

[0018] Preferably, the raw material cabin comprises a base and a top cover, and the base and the top cover are fixed by welding.

[0019] From the above description of the present invention, it can be seen that the present invention has the following beneficial effects: The foam shield structure provided by the present invention integrates the stock liquid delivery pump and the air delivery pump into one, thereby reducing the number of pumps, avoiding high costs and complicated installation problems, and the overall noise is relatively reduced during operation. In addition, by providing a flow controller in the second gas path, the gas flow ratio of the two gas paths can be controlled, which can not only provide gas according to demand, but also avoid the problem of insufficient air pressure provided by the first gas path and extrusion of viscous stock liquid. The flow controller is a replaceable flow limiting small tube, which has a simple structure and can be replaced according to actual requirements, and has low cost; The flow controller is a control valve, which can adjust the flow of the second gas path at will, making it convenient for consumers to adjust by themselves; The flow controller is provided with a normal gear and a saving gear, providing consumers with flexible choices.
