Description

一种泡沫发生装置及应用该装置的浴缸和便器Foam generating device and bathtub and toilet using the same 技术领域Technical field

背景技术Background technique
泡沫时常被应用于泡泡浴以及便器，Foams are often used in bubble baths and toilets.
常用的泡泡浴，往往是由含有表面活性剂、蛋白、甘油等化学成分的泡泡浴液在水流的冲击下与空气混合而形成。这种泡泡的洗浴效果不佳：1)持泡时间短，因为这种产生泡沫的方式仅是利用水流冲击产生，所以泡沫大，容易破碎；2)体验不好，因为泡沫颗粒大小不足，持泡时间短，所以用不了多久泡沫就自然消失了，无法持久覆盖在人身上；3)用量大，为了能够利用水流冲击产生泡沫，不得不采用较大的浴液浓度，从而造成浪费。Commonly used bubble baths are often formed by mixing a bubble bath containing a chemical component such as a surfactant, a protein, or a glycerin with air under the impact of a water stream. The bathing effect of this kind of bubble is not good: 1) The bubble holding time is short, because the way of generating foam is only generated by the impact of water flow, so the foam is large and easy to be broken; 2) the experience is not good, because the foam particle size is insufficient, The foaming time is short, so the foam will disappear naturally after a long time, and it cannot be covered for a long time. 3) The amount is large. In order to be able to use the water flow to generate foam, a large bath concentration has to be used, resulting in waste.
而泡沫应用于便器，起到防止臭味和阻隔细菌扩散的作用。作为核心的发泡技术，主要有两种方式：一种是使用带有大量过滤孔的材料分散含有发泡剂的气水混合物，如图1所示；还有一种方式是采用文丘里管形式，利用突变的收缩段来进行空气混合，如图2所示；其他的方式还有如采用搅拌电机等将空气与含有发泡剂的水混合在一起的方式。The foam is applied to the toilet to prevent odor and block the spread of bacteria. As the core foaming technology, there are two main methods: one is to use a material with a large number of filter pores to disperse the gas-water mixture containing the foaming agent, as shown in Figure 1; another way is to use the venturi form The abrupt shrinkage section is used for air mixing, as shown in Fig. 2; in other ways, a method of mixing air with a water containing a blowing agent, such as a stirring motor, is used.
以上这些方法，如采用滤材类进行发泡的问题是容易堵塞，尤其是需要制造直径细小的泡沫时，需要用到孔隙度非常小的滤材，导致发泡效率在使用后迅速下降。The above methods, such as the use of a filter material for foaming, are prone to clogging, and in particular, when it is required to produce a foam having a small diameter, a filter material having a very small porosity is required, resulting in a rapid decrease in foaming efficiency after use.
文丘里形式的发泡获得用于覆盖便污和杀菌的优质泡沫的前提是，1)添加发泡剂，降低水表面张力，2)充分的气水混合。实现充分的气水混合是获得优质泡沫的基础。The premise of foaming in the form of venturi to obtain a high-quality foam for covering dirt and sterilization is 1) adding a foaming agent to lower the surface tension of water, and 2) mixing with sufficient gas and water. Achieving adequate gas-water mixing is the basis for quality foam.
然而存在问题是，由于水压不稳定，很多地方的水压保证稳定，采用文丘里形式的发泡泡沫很难控制发生量。However, there is a problem in that the water pressure in many places is stable due to the unstable water pressure, and it is difficult to control the amount of foaming in the form of venturi.
采用固定目数的过滤器或曝气石能够将气体进行直接分切，一次性产生泡沫，这种泡沫的致密性取决于过滤器的目数，在获取更加细腻泡沫时候需要用到目数高于100的分散材料，这导致滤片堵塞，而由于空气在不同滤材部分压力的不同，仅有一部分滤孔起到作用，其他部分则为水淹没。文丘里形式的发泡器则使用很小孔径的喷水孔实现对空气的切割，进而实现泡沫产生，水压对泡沫产生起到决定性作用。The fixed mesh filter or aerated stone can directly cut the gas and produce foam at one time. The compactness of the foam depends on the mesh of the filter and requires a high mesh when obtaining a finer foam. At 100% of the dispersed material, this causes the filter to become clogged, and due to the difference in pressure of the air in the different portions of the filter, only a portion of the filter holes function, and the other portions are flooded. The venturi-style foamer uses a small pore size water jet to cut the air, which in turn produces foam, which is decisive for foam generation.
另外，在较低发泡剂存在的情况下，对滤材而言，如果采用连续发泡的方式，由于气压的作用会使大量含有发泡剂的水被泡沫带出，造成浪费。混合效果较差，所以在连续发泡装置中，不是好的技术方案。文丘里形式的发泡设备适合连续产生泡沫，但是受制于水压的限 制，导致低压情况下气水混合效果很差，所以往往出现大泡的现象。Further, in the case where a lower blowing agent is present, if a continuous foaming method is employed for the filter medium, a large amount of water containing a foaming agent is carried out by the foam due to the action of the gas pressure, resulting in waste. The mixing effect is poor, so in a continuous foaming device, it is not a good technical solution. Venturi-style foaming equipment is suitable for continuous foam generation, but subject to water pressure limits Because of the low pressure, the gas-water mixing effect is very poor, so there is often a phenomenon of large bubbles.

Because the static mixing device changes the direction of fluid movement to achieve a very fine foam of mixed water, gas and liquid. Non-prior art commonly used particle packings and/or porous structures utilizing fine pore sizes produce foam, thus producing the same foam quality, the corrugated plate gap in the static mixing device of the present invention is much larger than the particle packing and/or porous The structure gap is not easy to be clogged, the use experience is good, the service life is long, and the static mixing device generates foam without requiring a large water pressure, and the high quality foam can be continuously produced even under the pressure of 0.01 Mpa. Since the static mixing device can sufficiently mix water, gas and liquid, at a lower concentration of the blowing agent, a higher amount of foam generation can be produced, and the foaming liquid can be more saved. The foam generating device of the present invention can be applied to a bathtub and a toilet, using a static mixer The utility model has the advantages of small volume and high foaming efficiency, and achieves high-efficiency foaming in a narrow space.

The body 26b and the cleaning water inlet branch 6 are provided with a water flow pipe 5 at the rear of the static mixing device 3. When a foam is required, the solenoid valve control line injects tap water and a blowing agent into the first cavity 26a, and injects air into the second cavity 26b, the first cavity 26a is used to premix and mix the tap water and the blowing agent. After the liquid is delivered to the second chamber 26b, the dilute solution of the blowing agent and the air are premixed in the second chamber 26b to form a gas-water mixture, which enters the static mixing device 3, and the static mixing device 3 utilizes a built-in The static mixing unit and the continuously twisted fins can continuously change the flow direction of the gas-water mixture and cut the gas-water mixture multiple times, so that the gas-water mixture generates a large amount of fine foam, and the fine foam enters the water outlet pipe 27 due to the resistance of the static mixing device 3, when In the case where the water pressure is low, the flow rate of the foam is slow, it may accumulate near the outlet, or the inner surface of the toilet may not be brushed and covered in a large area. Therefore, in this embodiment, the end of the static mixing device 3 is provided with a slave. The water flow pipe 5 connected to the lower side, the water flow from the water flow pipe 5 quickly takes out the foam from under the foam, and the foam can be quickly washed out from the water outlet pipe 27 and washed by the toilet. Any hole above the clean surface enters the surface of the water seal. Before the end of one foaming, the intake air and the foaming liquid are stopped, only the tap water is fed, the water flows through the first cavity 26a and the second cavity 26b, and the residual foam in the pipeline is cleaned to ensure the first cavity 26a and the second cavity.
