Description

Technical Field

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

[0002] The foam shield is a new toilet function that not only has the function of blocking odors with a water seal, but also has a better appearance compared to a water seal. In addition, it does not bring the unpleasant experience of water splashing, 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 deliver water, foam liquid and air respectively. The structure with multiple pumps has the following problems: 1. High cost; 2. Relatively cumbersome installation; 3. Multiple pumps working at the same time, making a lot of noise; 4. Poor coordination between pumps, and after long-term use, the aging speed of the pumps may be different, which will cause large errors in the discharge ratio of the materials. To this end, the utility model provides a new foam shield structure that can solve the above technical problems. Utility Model Content

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

[0004] A foam shield structure comprises a raw liquid chamber, a mixing chamber, a pump body and a foam shield generator.

[0005] The original liquid chamber is provided with a liquid outlet channel connected to the mixing chamber, so that the original liquid can be transported into the mixing chamber through the liquid outlet channel, and 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 pump body's air outlet includes a first air path and a second air path, with the second air path equipped with a flow controller. The first air path extends into the raw liquid chamber, inflating it. The raw liquid chamber uses air pressure to pressurize the raw liquid within through the liquid outlet channel into the mixing chamber. Both the second air path's air outlet and the mixed liquid outlet are connected to the feed port of a foam shield generator, which serves as the foam-generating material.

[0007] The foam shield structure provided by the utility model 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 on the second air path, the air flow ratio of the two air paths can be controlled, which not only can provide gas according to demand, but also can avoid the problem of insufficient air pressure provided by the first air 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 pore sizes can be selected.

[0009] Preferably, the flow controller is a control valve, which is installed inside the second air path 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 air paths. The structure is simple and easy to control.

[0010] Preferably, the control valve is provided with a normal gear and a saving gear for users 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 connected to the feed end of the foam shield generator through 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 contaminating the water source.

[0018] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0019] The foam shield structure provided by the utility model 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 relatively reducing the overall noise 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 not only can provide gas according to demand, but also avoids the problem of insufficient air pressure provided by the first gas path and squeezing out viscous raw liquid.

[0020] The flow controller is a replaceable flow limiting tube with a simple structure and can be replaced according to actual requirements at a low cost.

[0021] The flow controller is a control valve that can adjust the flow of the second gas path at will, making it convenient for consumers to adjust it themselves;

[0022] The flow controller is provided with a normal gear and a saving gear, providing consumers with flexible choices. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] The raw liquid chamber 1 is provided with a liquid outlet channel 5 connected to the mixing chamber 2, so that the raw liquid can be transported into the mixing chamber 2 through the liquid outlet channel 5. Preferably, the liquid inlet end of the liquid outlet channel 5 extends to the bottom of the raw liquid chamber 1, and the liquid outlet end extends to the top of the mixing chamber 2, and a one-way valve 6 is provided in the liquid outlet channel 5 to prevent the mixed liquid from entering the raw liquid chamber 1.

[0037] The mixing chamber 2 is provided with a water inlet 21 and a mixed liquid outlet 22 for introducing water and discharging the mixed liquid respectively.

[0038] In one embodiment, a raw liquid injection pipe 11 is provided at the top of the raw liquid chamber 1, and a one-way valve 6 is provided in the raw liquid injection pipe 11 to avoid the situation where the raw liquid cannot be transported to the mixing chamber 2 due to pressure relief. A liquid level sensor 12 is provided on the periphery of the raw liquid chamber 1, which has a low liquid level alarm function to remind the user to replenish the raw liquid. A drain port is provided at the bottom of the raw liquid chamber 1, and a plug 13 is provided at the drain port. By opening the plug 13, the raw liquid in the raw liquid chamber 1 can be discharged, which facilitates the cleaning of the raw liquid chamber 1. A water inlet pipe is provided at the top of the mixing chamber 2, and a one-way valve 6 is provided in the water inlet pipe to prevent the mixed liquid from contaminating the water source.

[0039] The gas outlet of the pump body 3 includes a first gas path 31 and a second gas path 32, and the second gas path 32 is provided with a flow controller 321. Preferably, the first gas path 31 and the second gas path 32 are connected to the gas outlet of the pump body 3 via a three-way joint, which is easy to assemble.

[0040] In this embodiment, the flow controller 321 is a replaceable flow-limiting tube, which is blocked inside the second air path 32 and provided with an air hole, thereby reducing the exhaust volume of the second air path 32 and increasing the air pressure of the first air path 31. When other proportions of foam generating materials are required, replaceable flow-limiting tubes with other different apertures can be selected.

[0041] In another embodiment, see Figure 8 The flow controller 321 is a control valve installed inside the second air path 32 and equipped with a flow adjustment switch. The user can control the air output ratio of the two air paths simply by adjusting the flow adjustment switch. This simple structure makes it easy to control. Preferably, the control valve has a normal gear and a saving gear for the user to choose. When the normal gear is selected, the foam produced is thicker, with small, dense bubbles. When the saving gear is selected, the bubbles produced are sparser, larger, and more sparse, without affecting the foam shield function, thereby saving raw liquid.

[0042] The air outlet of the first air path 31 extends into the raw liquid chamber 1, inflating it. The raw liquid chamber 1 uses air pressure to pressurize the raw liquid within into the mixing chamber 2 through the liquid outlet channel 5. The air outlet of the second air path 32 and the mixed liquid outlet 22 are both connected to the feed end of the foam shield generator 4, which serves as the foam-forming material. Preferably, the mixed liquid outlet 22 is connected to a mixed liquid outlet pipe, which is connected to the second air path 32 via a three-way joint to the feed end of the foam shield generator 4, facilitating assembly.

In addition, by providing a flow controller 321 in the second air path 32, the air flow ratio of the two air paths can be controlled, which not only can provide gas according to demand, but also can avoid the problem of insufficient air pressure provided by the first air path 31 and squeezing out viscous raw liquid.
