In some embodiments, the housing 100 is generally flat in configuration. In this way, after the cabinet 100 is mounted on the wall, since the cabinet 100 has a flat structure, the water valve module and the water treatment cartridge 240 are mounted so that the cabinet 100 can be abutted against the wall and an internal mounting space is formed using an area of the wall. In addition, the flat structure of the housing 100 can reduce the occupation of the effective bathroom space of the housing 100 and reduce the collision of users with the housing 100 in the bathing process. In addition, the water valve module is integrated in the casing 100, and the wall-mounted installation height of the casing 100 is suitable for a user to operate the water valve module, so that the casing 100 can be installed by using the installation space of the original water mixing valve in the user's home.

In an embodiment of the present application, the water inlet pipe passes through the back plate of the casing 100 and protrudes to the outside of the casing 100.

In particular, the water inlet pipe extends from the back plate of the cabinet 100 to the outside to connect with a water supply pipe orifice on a wall of a user's home. Typically, the inlet conduit is disposed laterally to further facilitate carrying the housing 100 and the water valve module and water treatment cartridge 240 within the housing 100 through the inlet conduit. In addition, for water entering the water valve module, generally, cold water and hot water are separated, and the water inlet pipes may be respectively disposed at both sides of the casing 100, wherein one of the water inlet pipes is used for conveying cold water and the other water inlet pipe is used for conveying hot water.

Specifically, after the two ends of the water treatment filter element 240 are respectively and fixedly installed through the external interface 2103 and the supporting part 120, at least one second installation seat is configured on the water treatment filter element 240 in the length direction, and the concave part formed by the second installation seat can further position and support the middle area of the water treatment filter element 240, so that the installation reliability is further improved.

In the actual assembly process, the temperature control valve core 220 is installed in the first installation space, the waterway control valve core 230 is installed in the second installation space, and the two installation spaces are connected through a connecting channel 2104 arranged inside the shell 210, and since the connecting channel 2104 is built in the shell 210 and connects the first installation space with the second installation space in advance according to design requirements, the assembly can be completed only by installing the temperature control valve core 220 and the waterway control valve core 230 in the corresponding installation spaces during the assembly, so that the valve core assembly process is reduced, and the connection is performed one by one through water pipes, thereby simplifying the assembly process. In addition, when the user installs at home, the water inlet port 2101, the water outlet port 2102 and the outer port 2103 are also connected with corresponding installation spaces through the internal connecting channels 2104, and when the field assembly is further realized, only the water pipe of the external water supply pipe is required to be correspondingly connected with the water inlet port 2101 and the water outlet port 2102.

The water treatment cartridge 240 may be connected to the external port 2103 at the factory stage, or may be connected to the external port 2103 when assembled in the home of the user. The water treatment cartridge 240 may be implemented as a conventional water cartridge, such as: the water purifying filter element, the aromatherapy filter element, the foam filter element and the like can be used for respectively realizing the functions of water purification, aromatherapy and air bubble, so that the multifunctional experience can be realized, and the concrete entity of the water treatment filter element 240 is not limited and described in detail herein.

Water flowing out of the water outlet 2102 flows into the throat where it flows and is treated by flowing through the sintered cartridge 1. Because the sintering filter element 61 has a micro-gap (pore) structure, air can enter the throat pipe through the micro-gap of the sintering filter element 61 to be mixed with water, and because the micro-gap of the sintering filter element 61 is small, the air can be sheared, and then becomes fine air with higher pressure, meanwhile, the air is matched with the throat pipe structure, so that the flow velocity of the water is increased, the pressure is lowered, more air and water can be more easily fused into the air, and the formed micro-bubble water can contain 10 air bubbles per milliliter ⁶ Therefore, the generated micro bubble water has better effect and can continuously generate micro bubble water. In addition, the bubble pitch diameter of the micro bubble water generated by the micro bubble generator can reach 47 micrometers under 0.3MPa, and the micro bubble generator is smaller than that generated by the bubble generator in the prior art, so that the cleaning effect is better.

In some embodiments, there are various ways in which the flow path of the water flow input by the water inlet port 2101 can be made.

For example: the water flow entering the water inlet port 2101 is sequentially output from the water outlet port 2102 through the water channel control valve core 230, the temperature control valve core 220, the water treatment filter core 240 and the water channel control valve core 230. Specifically, after water supplied by the external water supply network enters from the water inlet port 2101, the water flows through the waterway control valve core 230, so that the waterway on-off can be conveniently controlled through the waterway control valve core 230; then, the water flow enters the temperature control valve to regulate and control the temperature; the water with the adjusted temperature enters the water treatment filter element 240 for water quality treatment, and finally is output to the water using end of the water supply network from the water outlet interface 2102 through the waterway control valve element 230.

Alternatively, the water flow entering through the water inlet port 2101 is sequentially output from the water outlet port 2102 through the temperature control valve core 220, the water path control valve core 230, the water treatment filter core 240 and the water path control valve core 230;

alternatively, the water flow entering the water inlet port 2101 is outputted from the water outlet port 2102 via the temperature control valve cartridge 220, the water treatment valve cartridge 240, and the waterway control valve cartridge 230 in this order.

In an embodiment of the present application, as shown in fig. 3-5, for the connection channel 2104 arranged in the housing 210, the connection channel 2104 is built in the housing 210, and because the internal space of the housing 210 is limited and the connection requirements of different water flow paths are also required to be met, in order to reduce the processing difficulty of forming the connection channel 2104 in the housing 210, for the connection channel 2104, according to the positions of different connection channels 2104 inside the housing 210 and the requirements of waterway connection, as shown in fig. 5, part of the connection channel 2104 is a complete waterway channel directly formed in the housing 210, while for the rest of the connection channels 2104, the connection channel 2104 is formed in the housing 210 in a split connection manner.

Specifically, as shown in fig. 4, the connecting channel 2104 includes two main water channels 21041 and an auxiliary water channel 21042, the two main water channels 21041 are arranged in parallel and staggered, the auxiliary water channel 21042 and the two main water channels 21041 are staggered and respectively communicated with the two main water channels 21041, and one port of the auxiliary water channel 21042 is located on the outer surface of the casing 210 and is provided with a plug 21043. The two main waterways 21041 are not arranged in a collinear way, and are staggered up and down or staggered left and right, while the auxiliary waterway 21042 is connected with the two main waterways 21041 in a penetrating way so as to realize the bending and conveying of the water by the connecting channel 2104.

Thus, in the actual processing, conventional processing methods such as injection molding are generally used for the housing 210. For the integral connecting channel 2104, the integral connecting channel is integrally arranged in the shell 210, for the connecting channel 2104 with a split design, the auxiliary water channel 21042 is matched with the two main water channels 21041 to form the connecting channel 2104, one port of the auxiliary water channel 21042 is positioned on the surface of the shell 210 to facilitate processing and forming, and meanwhile, the port of the auxiliary water channel 21042 is further sealed by the plug 21043.

In another embodiment of the present application, for the temperature control valve core 220, a constant temperature valve core is preferably adopted, and two water inlet interfaces 2101, namely a first water inlet sub-interface and a second water inlet sub-interface, are correspondingly configured;

The first installation space is provided with a first inlet (not marked), a second inlet (not marked) and a mixed water outlet (not marked), the first inlet and the second inlet are arranged on one side of the constant-temperature valve core, the mixed water outlet is arranged at the end part of the constant-temperature valve core, and the constant-temperature valve core is used for adjusting the water inflow of the first inlet and the second inlet according to the water outlet temperature of the mixed water outlet;

the water flow input by the first sub water inlet interface enters the first inlet, the water flow input by the second sub water inlet interface enters the second inlet, and the water flow output by the water mixing outlet is output from the water outlet 2102.

Specifically, the two water inlet ports 2101 respectively introduce water with different temperatures, namely hot water and cold water, the cold water and the hot water respectively flow into the constant temperature valve core through the first inlet and the second inlet, the constant temperature valve core automatically controls the proportion of the cold water and the hot water according to the outlet water temperature regulated by a user, and finally the water with the set temperature is output from the mixed water outlet. The specific structural form of the thermostatic valve core for automatically adjusting the ratio of cold water to hot water can refer to the valve core structure in a conventional thermostatic valve, and is not limited and described in detail herein.

In order to better illustrate the above principle, the above microbubble generator will be described below in a specific configuration.

As shown in fig. 21 and 22, the microbubble generator includes a sintered filter element 61, a first conduit 62, a second conduit 63, and a gas conduit 64, wherein:

one end of the second pipe 63 is sealed in the first pipe 62, the throat is formed between the second pipe and the sintered filter element 61, and the sintered filter element 61 is disposed at the throat of the throat. Illustratively, a first fluid passage 621 is provided in the first duct 62, one end of the first fluid passage 621 adjacent to the second duct 63 includes a first variable diameter section, and the diameter of the first variable diameter section is gradually reduced in a direction toward the second duct 63, a second fluid passage 631 is provided in the second duct 63, one end of the second fluid passage 631 adjacent to the first fluid passage 621 includes a second variable diameter section, and the diameter of the second variable diameter section is gradually reduced in a direction toward the first duct 62, and the sintered filter element 61 is disposed between the first variable diameter section and the second variable diameter section, by which the first fluid passage 621, the sintered filter element 61, and the second fluid passage 631 can collectively form the throat structure described above. When water is introduced, the throat tube can generate adsorption force to suck air to flow to the micro gaps between the sintering filter elements 61, and the air is sheared into finer air with higher pressure by the micro gaps, and then the air is mixed with the water to form micro-bubble water.

The first pipe 62 is provided with a gas communication hole 622, and the gas communication hole 32 is provided so as to face the sintered filter element 61, and outside air can flow through the gas communication hole 622 to the sintered filter element 61 and then enter the throat through the micro gap of the sintered filter element 61. The gas pipe 64 of the present embodiment may be screwed to the gas communication hole 622, and a gas passage is provided in the gas pipe 64, the gas passage being connected to the gas communication hole 622, and the outside air being introduced into the gas communication hole 622 and then into the micro gap of the sintered filter element 61 through the gas passage.

It should be noted that, in this embodiment, the air pipe 64 may be further connected to an air source capable of delivering air, such as an air pump 610 (as shown in fig. 21), which can increase the pressure of the air, and the air after being sheared enters the throat pipe with a higher pressure and is mixed with water, so that the effect of forming micro-bubble water is better.

Preferably, one end of the second pipe 63 is fixedly connected to the first pipe 62 by a bolt, specifically, flange structures may be provided on the first pipe 62 and the second pipe 63, and then the first pipe 62 and the second pipe 63 may be fixed by the bolt and the flange structures. The second pipe 63 and the second pipe 63 may be fixed by other means, such as screwing.

In this embodiment, a rubber gasket 65 is further disposed between the sintered filter element 61 and the first pipe 62, and by the arrangement of the rubber gasket 65, the sintered filter element 61 is prevented from being damaged due to impact of water flow on the sintered filter element 61, that is, the pressure of the water flow is buffered by the rubber gasket 65 and does not directly act on the end face of the sintered filter element 61, so that the sintered filter element 61 is also effectively protected. In addition, the rubber gasket 65 can also avoid damage such as crashing and crush injury to the sintered filter element 61 when the first pipe 62 is assembled in the process of assembling the microbubble generator of the present embodiment.

Referring to fig. 21 and 22, the microbubble generator of the present embodiment further includes a third pipe 66, where the third pipe 66 is connected to an end of the first pipe 62 away from the sintering filter element 61 in a sealing manner, and the third pipe 66 is provided with a third liquid channel 661 that communicates with the first liquid channel 22. A liquid inlet 662 communicating with the third liquid passage 661 is provided in the third pipe 66, and water can enter the third liquid passage 661 through the liquid inlet 662 and then the first liquid passage 22. In this embodiment, one end of the third pipe 66 is disposed in the first pipe 62, and is fixedly connected with the first pipe by a flange and a bolt, and a sealing ring is disposed between the first pipe and the second pipe for sealing.

As shown in fig. 21, the microbubble generator of the present embodiment further adds a bypass pipe 67, and the bypass pipe 67 is illustratively connected to both sides of the throat. By arranging the bypass pipeline 67, a part of water can flow through the throat and be mixed with fine air to form micro-bubble water, and the other part of water is mixed with the formed micro-bubble water, so that the bubble content in the micro-bubble water flowing out of the liquid outlet is changed. In this embodiment, one end of the bypass pipe 67 is connected to the liquid inlet 662 of the third pipe 66, and the other end is connected to the second pipe 63 (as shown in fig. 22 and 19, the second pipe 63 has a connection hole 632 for connecting to the second liquid channel 631, and the bypass pipe 67 is connected to the connection hole 632 in a sealing manner). In this embodiment, the bypass conduit 67 has a diameter greater than the maximum diameter of the throat.

In order to better realize stepless adjustment of the bubble content in the micro bubble water flowing out of the liquid outlet, the micro bubble generator of the embodiment further comprises a distribution valve 68, wherein the inlet of the distribution valve 68 is communicated with the liquid inlet 662 of the third pipeline 66, two outlets are respectively communicated with the bypass pipeline 67 and the third liquid channel 661, the proportion of water entering the bypass pipeline 67 and the third liquid channel 661 can be adjusted through the distribution valve 68, the bubble content of the micro bubble water formed at the throat can be further changed, and the bubble content of the micro bubble water finally formed can be adjusted through the mixing of the water in the bypass pipeline 67 and the micro bubble water formed in the second liquid channel 631, so that the requirements of different users can be met. In addition, the distribution valve 68 is provided, so that the pressure of water entering the throat pipe can be adjusted, and the problem that air cannot be effectively dissolved due to excessive water pressure is avoided, and the generation probability of micro-bubble water is further improved. The dispensing valve 68 is of a construction common in the art and the construction and principles thereof are not discussed herein.

In this embodiment, the proportion of water entering the bypass conduit 67 and the third liquid passage 661 is adjusted by the distribution valve 68 in the following manner: when the flow rate of the water entering the bypass pipe 67 is increased, the corresponding flow rate entering the third liquid channel 661 is reduced, the bubble content in the micro bubble water is reduced, otherwise, the flow rate entering the third liquid channel 661 is increased, the bubble content in the micro bubble water is increased, and the generation of micro bubble water with different requirements by a user is further satisfied. And since the diameter of the bypass pipe 67 is larger than the maximum diameter of the throat, the total output flow of the whole micro bubble water generator is adjusted depending on the adjustment of the flow rate of the water in the bypass pipe 67 by adjusting the flow rate of the water entering the bypass pipe 67, although the flow rate of the water in the throat also varies.

Preferably, a third conduit 66 is provided at one end with 69, which 69 is used to detect flow, pressure and/or temperature. For example, the 69 may be a temperature sensor for detecting the temperature of water flowing into the third liquid passage 661, a pressure sensor for detecting the pressure of water flowing into the third liquid passage 661, or a flow sensor for detecting the flow rate of water flowing into the third liquid passage 661. It is also possible to detect two or more of temperature, pressure and flow rate simultaneously. Through detecting flow, pressure and/or temperature, can cooperate the controller to realize the control to rivers flow, pressure and temperature to satisfy different demands.

The control method of the microbubble generator 600 includes the steps of:

s1, acquiring the water inlet pressure entering the throat.

Illustratively, the pressure of the water entering the third fluid passage 661, i.e., the inlet water pressure, is sensed by 69.

S2, judging whether the water inlet pressure is larger than a first preset pressure value, if not, entering a step S3, and if so, entering a step S4.

And S3, when the water inlet pressure is smaller than or equal to a first preset pressure value, automatically adsorbing air to the throat part of the throat pipe through the throat pipe and mixing the air with water to form micro-bubble water.

When the water inlet pressure is smaller than or equal to a first preset pressure value, the water inlet pressure can not cause blocking and other effects on the dissolution of air, and then the air can enter the throat and be mixed with water only through automatic adsorption of the throat, and the formed micro-bubble water has a sufficient effect.

And S4, judging whether the water inlet pressure is larger than a second preset pressure value when the water inlet pressure is larger than the first preset pressure value, if not, entering a step S5, and if so, entering a step S6.

In this step, the second preset pressure value is greater than the first preset pressure value.

And S5, pumping air to the throat through the air pump 610 when the water inlet pressure is between a first preset pressure value and a second preset pressure value.

When the water inlet pressure is between a first preset pressure value and a second preset pressure value, the water inlet pressure can cause a certain influence on the dissolution of air at the moment, and the effect of the formed micro-bubble water can be influenced only through the automatic adsorption of the throat pipe. Therefore, the air pump 610 pressurizes and pumps air to the throat, and the air can be more easily dissolved into water by matching with the automatic adsorption of the throat, so that the effect of the formed micro-bubble water is better.

And S6, when the water inlet pressure is larger than a second preset pressure value, adjusting the flow of water entering the throat through the distribution valve until the water inlet pressure is smaller than or equal to the second preset pressure value, and then pumping air into the throat through the air pump.

When the water inlet pressure is larger than a second preset pressure value, the water inlet pressure can seriously affect the dissolution of air at the moment, and the automatic adsorption of the throat pipe can not effectively dissolve the air into water. And at this time, even if air is pumped by the air pump, the air still cannot be better dissolved into water due to the overlarge water inlet pressure. Therefore, the pressure of the inlet water needs to be adjusted, specifically, the inlet water can be split by the distributing valve 68, and part of the water is discharged through the bypass pipeline 67, so that the pressure of the water entering the throat pipe is smaller than or equal to the second preset pressure value, and then the air is pumped to the throat part by the air pump 610 in a pressurizing manner, and at the moment, the air can be more easily dissolved into the water by matching with the automatic adsorption of the throat pipe.

It should be noted that, in this step, the distribution valve 68 is usually adjusted to the pressure of the water entering the throat pipe to be equal to the second preset pressure value, however, due to different control precision of the distribution valve 68, the pressure of the water entering the throat pipe may be smaller than the second preset pressure value, so that when the pressure is smaller than the second preset pressure value, the air pump 610 pressurizes the pumped air to the throat pipe to complete the formation of the micro bubble water.

Preferably, in order to achieve better energy saving, the present embodiment may control the air pump 610 to intermittently pump air when the air pump 610 is started.

In the second embodiment, for the waterway control valve core 230, the main function is to control the on-off of the waterway, and also to adjust the water flow. In order to meet the requirements of multi-waterway cut-off control and multi-waterway connection, as shown in fig. 6-8, the waterway control valve core 230 includes a fixed valve plate 231 and a rotary valve plate 232, and at least one inlet and outlet set is disposed on the fixed valve plate 231, and the inlet and outlet set includes two water inlets 2311; the rotary valve plate 232 is provided with a communication groove 2321 matched with the inlet and outlet group;

And the on-off control of the two inlets 2311 in the same inlet group is controlled by the rotary valve plate 232. The water inlet 2311 is connected to the corresponding connection passage 2104.

When two connection channels 2104 are required to be connected, the rotary valve plate 232 rotates to connect the two water inlets 2311 in the same water outlet group through the connection groove 2321, so as to connect the two connection channels 2104 with each other. Meanwhile, the water flow rate is further controlled by controlling the overlapping area between the communication groove 2321 and the water inlet 2311.

When the two connection channels 2104 need to be disconnected, the rotary valve plate 232 rotates, so that the connection between the communication groove 2321 and the water inlet 2311 is disconnected, and further disconnection of the two connection channels 2104 is achieved.

Wherein, the water diversion disk 234 is provided with a second positioning protrusion 2342, and the second positioning protrusion 2342 is inserted into the notch 2331.
