DETAILED DESCRIPTION

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Although the water purification component in the existing smart toilet water tank can purify water, due to the long water path between the water tank and the water outlet component, the water after preliminary filtration in the water tank may suffer from secondary contamination due to factors such as the pipeline environment or residence time when flowing through this long water path, thereby affecting the final water quality and user experience.

[0047] In order to solve the above technical problems, this embodiment provides a smart toilet. Figure 1 and Figure 2 As shown, Figure 1 is a structural block diagram of the smart toilet in the embodiment of the present application, Figure 2 It is a three-dimensional diagram of the smart toilet in the embodiment of the present application.

[0048] The smart toilet of this embodiment includes a water purification device 1, a water tank 2, a water pump 3 and a water outlet assembly.

[0049] The water pump 3 is connected to the water tank 2 and is configured to pump the water in the water tank 2 to the water purification device 1 .

[0050] The water purification device 1 includes a mounting seat 11, a descaling component and a scale inhibition component. The descaling component is configured to descaling water pumped by the water pump 3, and the descaling component is configured to inhibit scale of the water pumped by the water pump 3. Either the descaling component or the scale inhibition component can be detachably mounted in the mounting seat 11, so that the water purification device 1 can switch between the descaling and scale inhibition functions to process the water pumped by the water pump 3.

[0051] The water outlet assembly is connected to the output end of the water purifier 1 and is configured to receive the filtered water output by the water purifier 1 and spray the filtered water to a predetermined position. The water outlet assembly can be an existing spray bar 4 or other water spraying device according to different shapes.

[0052] Exemplarily, the smart toilet also includes an instant heater 5, which is connected between the water purification device 1 and the water outlet component, and is configured to receive and heat the filtered water output by the water purification device 1, and transport the heated water to the water outlet component, thereby realizing a heating function, making the water sprayed from the water outlet component at an appropriate temperature, and improving user experience.

[0053] Exemplarily, the water flow input end of the water tank 2 is provided with a solenoid valve 6, and the solenoid valve 6 controls the input switch of the water.

[0054] Exemplarily, the smart toilet also includes a switching valve 7 arranged at the front end of the water outlet component, and the switching valve 7 is used to switch the water path, using water to be sprayed from different types of nozzles on the water outlet component to form different types of water splashes, thereby meeting different usage requirements.

[0055] The smart toilet of the above technical solution sets the water purification device 1 between the water tank 2 and the water outlet component. The water output from the water tank 2 is filtered by the water purification device 1, and the water path of the filtered water to the water outlet component is shortened, thereby reducing the risk and degree of secondary contamination of the water quality during the transportation process, and improving the safety of the water quality finally sprayed on the user.

[0056] In order to improve the quality of water used, existing smart toilets usually use descaling liquid and filter materials to remove scale and impurities in the water. However, most of the descaling liquid and filter materials on the market are installed in different products. In actual applications, if descaling liquid and filter materials need to be used at the same time, the products containing them need to be installed in different locations of the smart toilet water system. The independent and scattered settings of descaling liquid and filter materials occupy a large installation space. At the same time, the descaling liquid and filter materials need to be purchased and replaced separately, so the cost of use is relatively high.

[0057] In order to solve the above technical problems, this embodiment provides a water purification device 1, referring to Figures 3 to 5 As shown, Figure 3 This is an exploded view of the first embodiment of the water purification device of the present application. Figure 4 is a cross-sectional view of the first embodiment of the water purification device of the present application when it is installed in the forward direction. Figure 5 It is a cross-sectional view of the first embodiment of the water purification device of the present application when it is installed in reverse.

[0058] The water purification device 1 includes: a mounting seat 11 and a water purification component, and the water purification component is configured as any one of the descaling component and the anti-scaling component. The mounting seat 11 is provided with a cavity 110 and a switch valve 13, the cavity 110 is provided with a drain 111, and a water inlet 112 and a water outlet 113 are provided at the bottom, and the water inlet 112 and the water outlet 113 are controlled to be connected and blocked by the switch valve 13; the water purification component includes a water purification box that can be used to accommodate descaling liquid or filter material to form the descaling component or the anti-scaling component 12, the water purification box 12 is provided with a descaling end 101 and an anti-scaling end 102, the descaling end 101 is provided with a liquid outlet 103 for outputting descaling liquid and an outlet 105 for water flow, the anti-scaling end 102 is provided with a water inlet 104, and the water purification box 12 is also provided with a water drain 111. The descaling liquid can be an existing descaling liquid or cleaning liquid or other liquid with the function of purifying water quality. Among them, the water purification box 12 is detachably connected to the mounting seat 11 and can be fixed in the cavity 110 in the forward or reverse direction, that is, the descaling end 101 or the scale inhibition end 102 is facing the bottom of the cavity 110; the water purification box 12 is fixed in the cavity 110 in the forward direction, that is, when the descaling end 101 is facing the bottom of the cavity 110, the switch valve 13 is opened, and the liquid outlet 103 is connected with the water outlet 113, so that the descaling liquid in the water purification box 12 can flow from the liquid outlet 103 into the water outlet 113 under the action of air pressure or water pressure; the water purification box 12 is fixed in the cavity 110 in the reverse direction, that is, when the scale inhibition end 102 is facing the bottom of the cavity 110, the switch valve 13 is closed, the inlet 104 is connected with the water inlet 112, and the outlet 105 is connected with the drain 111.

[0059] For example, see Figure 5 As shown, the water purification box 12 is reversely fixed in the cavity 110 , that is, when the scale-inhibiting end 102 faces the bottom of the cavity 110 , a drainage channel connecting the outlet 105 and the drain port 111 is formed between the water purification box 12 and the mounting seat 11 .

[0060] It is understandable that the outlet 105 may also be arranged at other positions, such as at the scale-inhibiting end 102 and staggered from the inlet 104 , while the drain port 111 is arranged at the bottom of the mounting seat 11 .

[0061] The descaling process of the water purification device 1 of the above technical solution is as follows: Figure 4As shown, first, the preparation stage: confirm that the water purification box 12 has been loaded with an appropriate amount of descaling liquid; point the descaling end 101 of the water purification box 12 toward the bottom of the cavity 110, and ensure that it is firmly fixed. Then, the startup stage: the switch valve 13 is opened to establish a passage between the water inlet 112 and the water outlet 113; under the action of air pressure or water pressure, the descaling liquid flows into the water outlet 113 through the liquid outlet 103 of the descaling end 101. Finally, the operation stage: the descaling liquid continues to flow out of the liquid outlet 103, enters the smart toilet water system or other equipment that needs descaling, and realizes the descaling function. During use, the water purification box 12 can be disassembled as needed for cleaning or replacement of new descaling liquid.

[0062] The scale prevention / water purification process of the water purification device 1 of the above technical solution is as follows: Figure 5 As shown, first, the preparation stage: confirm that the water purification box 12 has been loaded with an appropriate amount of filter material (such as activated carbon, ultrafiltration membrane, etc.); then, point the scale-blocking end 102 of the water purification box 12 toward the bottom of the cavity 110, and ensure that it is firmly fixed. Then comes the startup stage: close the switch valve 13, ensure that the water inlet 112 is connected to the water inlet 104 of the scale-blocking end 102, and the drain 111 is connected to the water outlet 105 of the scale-blocking end 102. Finally, there is the operation stage: the water flows into the water inlet 104 of the scale-blocking end 102 through the water inlet 112; the water flows through the filtering effect of the filter material to remove impurities, microorganisms, etc. in the water; the filtered clean water flows out from the water outlet 105, enters the drain 111, and finally enters the smart toilet water system or other equipment that requires water purification. During use, the water purification box 12 is regularly disassembled and replaced with new filter materials according to the service life and filtering effect of the filter material.

[0063] The water purification device 1 and the smart toilet of the above technical solution contain the descaling liquid and the filter material separately or simultaneously through the water purification box 12. When the descaling liquid and the filter material are needed, they only need to be loaded into the water purification box 12 for use, without the need to install their respective carriers separately in different parts of the smart toilet water system as in the prior art, which can effectively reduce space occupation and improve the utilization efficiency of the bathroom space. It is also important that users do not need to purchase the carriers of the descaling liquid and the filter material separately, thereby saving the equipment purchase cost; at the same time, the water purification box 12 is detachable and reusable, and users only need to regularly replace the internal descaling liquid or filter material without replacing the entire device, which greatly reduces the cost in long-term use. It can be seen that the water purification device 1 and the smart toilet of the above technical solution can effectively reduce the occupied space and use costs and improve the user experience.

[0064] In one embodiment of the above-mentioned water inlet 112 and water outlet 113 being connected and blocked by the switch valve 13, see Figure 3 and Figure 4As shown, the mounting seat 11 is provided with a valve cavity 114 between the water inlet 112 and the water outlet 113, and the valve cavity 114 is provided with a cavity opening 115 communicating with the containing cavity 110; the switch valve 13 includes a valve core 131 and a spring 132, the valve core 131 is movably arranged in the valve cavity 114, and is used to control the communication and blocking between the water inlet 112 and the water outlet 113, and the spring 132 is arranged in the valve cavity 114, and is configured to drive the valve core 131 to move toward the cavity opening 115; the descaling end 101 is provided with a yield groove 120, and the clean The water box 12 is fixed in the cavity 110 in the positive direction, that is, when the descaling end 101 faces the bottom of the cavity 110, the valve core 131 passes through the cavity opening 115 driven by the spring 132 and extends into the clearance groove 120 to connect the water inlet 112 and the water outlet 113; the water purification box 12 is fixed in the cavity 110 in the reverse direction, that is, when the scale prevention end 102 faces the bottom of the cavity 110, the valve core 131 is pressed down by the water purification box 12 to between the water inlet 112 and the water outlet 113 to block the water inlet 112 and the water outlet 113. In this embodiment, the switch valve 13 not only has the function of regulating the on-off between the water inlet 112 and the water outlet 113, but also incorporates an automatic and adaptive control mechanism, and its operating logic can automatically respond to the installation status of the water purification box 12. Specifically, when the water purification box 12 is installed at the descaling end 101 toward the bottom of the cavity 110, the recess 120 provides the necessary space for the valve core 131, causing the valve core 131 to automatically rise under the driving force of the spring 132, thereby achieving smooth communication between the water inlet 112 and the water outlet 113. On the contrary, when the water purification box 12 is installed at the scale prevention end 102 toward the bottom of the cavity 110, its structural characteristics will effectively resist the elastic force of the spring 132 and press down the valve core 131, causing the water inlet 112 and the water outlet 113 to automatically close. At this time, the water flow at the water inlet 112 is guided into the interior of the scale prevention box 17 for necessary filtering treatment. This design not only improves the convenience of operation of the equipment, but also significantly enhances the flexibility and intelligence level of the system.

[0065] Exemplarily, the water purification box 12 includes two inner chambers separated from each other (not shown in the figure), which are separated by a partition and respectively provided with a descaling end 101 and a scale inhibition end 102, which can be used to contain descaling liquid and filter materials, respectively. In this way, a water purification box 12 can have both descaling and filtering functions. When in use, you only need to select the end with the corresponding function and insert it into the cavity 110. It is easy to use, and further simplifies the product structure and reduces the cost of use.

[0066] Further, in order to optimize the installation process of the valve core 131 and the spring 132, refer to Fig.11As shown, in this embodiment, a port is opened at one end of the valve cavity 114 of the mounting seat 11 away from the cavity opening 115, and a buckle cover 133 is installed on the port, whose main function is to seal the port and support the spring 132. The design of the buckle cover 133 allows one end of the spring 132 to abut against its inner side, while the other end of the spring 132 supports the valve core 131. In the installation process, the operator can place the valve core 131 and the spring 132 into the valve cavity 114 in sequence, and then tightly close the port through the buckle cover 133. This action not only completes the installation, but also compresses the spring 132 to force the valve core 131 to move toward the cavity opening 115 to achieve the expected pre-tightening state. Among them, the connection method between the buckle cover 133 and the port can be selected from a convenient buckle connection or a stable threaded connection, which ensures the firmness of the buckle cover 133. In addition, in order to prevent water from leaking through the gap, a sealing ring is also provided between the buckle cover 133 and the port, which not only enhances the sealing effect, but also significantly improves the waterproof performance and durability of the equipment. In summary, this embodiment not only simplifies the installation steps, but also ensures the overall performance and reliability of the equipment through precise design.

[0067] In order to ensure that the valve core 131 does not exceed the predetermined maximum stroke when moving toward the cavity 115, refer to Figure 4 and Figure 5 As shown, the valve core 131 in this embodiment is provided with a shoulder structure. When the descaling box 16 is firmly installed in the cavity 110, the shoulder structure will form an effective contact with the edge of the cavity opening 115, thereby limiting the valve core 131 from moving further toward the cavity opening 115.

[0068] Understandably, see Figure 4 and Figure 5 As shown, the assembly process of the valve core 131 and the spring 132 can also be completed through the above-mentioned cavity 115. In this case, the mounting seat 11 adopts a sealing structure integrally formed with the mounting seat 11 itself at the end of the valve cavity 114 away from the cavity 115, which not only simplifies the structure, but also further enhances the sealing performance, ensuring the integrity of the interior of the valve cavity 114 and the efficiency of water flow treatment.

[0069] In another embodiment (not shown) in which the connection and blockage between the water inlet 112 and the water outlet 113 are controlled by the switch valve 13, the connection and blockage between the water inlet 112 and the water outlet 113 are controlled by the switch valve 13 which acts as an electronic valve. The electronic valve is equipped with a control button, and its working state can intelligently respond to the installation state of the descaling box 16 and the anti-scaling box 17. Specifically, when the descaling end 101 is toward the bottom of the cavity 110, it presses down and activates the control button, which then triggers the electronic valve to open, so that a smooth connection path is established between the water inlet 112 and the water outlet 113. On the contrary, if the anti-scaling end 102 is toward the bottom of the cavity 110, due to its structural design with a give-way structure similar to the give-way groove 120, it cannot trigger the control button, and the electronic valve therefore remains closed, and the water flow between the water inlet 112 and the water outlet 113 is effectively blocked. In this embodiment, by accurately sensing the different installation conditions of the descaling end 101 and the antiscaling end 102 , the electronic valve can automatically adjust its working state, thereby ensuring the accuracy of water flow control and the stability of system operation.

[0070] In order to make the installation of the water purification box 12 more convenient, in the design of the water purification box 12, the descaling end 101 and the scale prevention end 102 are distributed at both ends of the length direction of the water purification box 12, which is convenient for functional distinction. Figure 3 As shown, the outer surface of the water purification box 12 is provided with guide ribs 106 along its length direction, and the inner side of the mounting seat 11 is provided with guide grooves 116 matching these guide ribs 106. When the water purification box 12 is installed, the guide ribs 106 will naturally slide into the guide grooves 116, which not only simplifies the installation process, but also ensures the accuracy of the installation. At the same time, the circumferential fixation between the water purification box 12 and the mounting seat 11 is achieved, so that the liquid outlet 103 on the water purification box 12 can be accurately aligned with the water outlet 113 and connected, or when the scale-blocking end 102 is facing downward, the inlet 104 of the water purification box 12 is aligned and connected with the water inlet 112, and the outlet 105 is also connected with the drain 111. It is particularly worth mentioning that the ingenious cooperation between the guide ribs 106 and the guide grooves 116 not only plays a role in guiding the installation, but also has a fool-proof function, effectively avoiding installation errors and ensuring that the water purification box 12 can be accurately installed in place.

[0071] It is understandable that the descaling box 16 and the antiscaling box 17 can also be quickly positioned on the mounting seat 11 by means of marking lines. Exemplarily, the descaling box 16 and the antiscaling box 17 are provided with marking lines on the top of the mounting seat 11. When the marking lines of the descaling box 16 and the antiscaling box 17 are positioned relative to the marking lines of the mounting seat 11, the liquid outlet 103 and the water outlet 113 are positioned relative to and connected to each other, or the inlet 104 and the water inlet 112 are positioned relative to and connected to each other, and the outlet 105 and the drain 111 are positioned relative to and connected to each other.

[0072] In one embodiment, the water purification box 12 can be fixed in the cavity 110 in a positive or reverse direction. Figure 3 , Figure 4 and Figure 5 As shown, the water purification device 1 further includes a rotating cover 14, which is connected to the mounting seat 11 via a rotating buckle 141 and is pressed onto the water purification box 12 so that the water purification box 12 and the mounting seat 11 are fixed in the receiving cavity 110. When removing the descaling box 16 or the antiscaling box 17, the rotating cover 14 only needs to be rotated in the opposite direction to disengage the rotating buckle 141, so that the receiving cavity 110 can be opened and the descaling box 16 or the antiscaling box 17 can be taken out.

[0073] For example, see Figure 3 As shown, the rotating cover 14 and the water purification box 12 are connected by a strong release buckle 142 to improve the firmness of the connection.

[0074] The rotating cover 14 can also be connected to the mounting seat 11 by means of threaded connection or tight connection, so that it can be fixed relative to the mounting seat 11 and opened when the descaling box 16 or the antiscaling box 17 is disassembled.

[0075] In other embodiments in which the above-mentioned cavity 110 can detachably fix the descaling box 16 or the antiscaling box 17, the descaling box 16 and the antiscaling box 17 are directly connected to the mounting seat 11 by threads or snaps, and an end cover is provided on the top, and the cavity 110 is sealed by the end cover when connected.

[0076] In order to facilitate identification of the descaling end 101 and the antiscaling end 102 and to facilitate adding descaling liquid into the descaling box 16, refer to Figure 3 and Figure 4 As shown, the water purification box 12 is provided with an opening, and a sealing cover 107 is provided at the opening, and the sealing cover 107 can prevent the descaling liquid from leaking out.

[0077] In the first embodiment, the descaling liquid of the water purification box 12 flows into the water outlet 113 from the liquid outlet hole 103 under the action of air pressure or water pressure. Figure 4As shown, the sealing cover 107 is provided with a one-way air inlet valve 108 for delivering air pressure to the inside of the water purification box 12, and the rotating cover 14 is provided with an air inlet hole 143 for delivering air pressure to the one-way air inlet valve 108; the water flow cross section of the water outlet 113 at the place where it is connected with the liquid outlet hole 103 first decreases and then increases along the water flow direction, and the water purification box 12 is fixed in the cavity 110 in the positive direction, that is, when the descaling end 101 is facing the bottom of the cavity 110, the descaling liquid in the water purification box 12 flows into the water outlet 113 from the liquid outlet hole 103 under the action of the Bernoulli principle. When the water purification box 12 is installed in the cavity 110, in its initial state, due to insufficient pressure conditions, the descaling liquid cannot be released freely or can only be released in a trace amount through the liquid outlet hole 103. When the water flows smoothly from the water inlet 112 to the water outlet 113, it will encounter a connecting area where the water flow cross section first shows a trend of shrinking along the water flow direction, and then gradually expands. It is this unique change in the cross-section of the water flow that cleverly utilizes the Bernoulli principle: in the area where the flow rate increases (cross-section decreases) and the pressure decreases, the descaling liquid in the descaling box 16 is effectively attracted and drawn out from the liquid outlet 103, and then mixed with the mainstream water flow, achieving the purpose of water purification. Next, in order to maintain the balance of the air pressure inside the descaling box 16, the system's built-in one-way air inlet valve 108 is activated in a timely manner to inhale external air, effectively compensating for the internal negative pressure state that may be generated by the release of the descaling liquid. In summary, this embodiment realizes the automatic utilization of the descaling liquid and the purification of the water quality through the water flow dynamics characteristics and the air pressure balance mechanism.

[0078] In the second embodiment, the descaling liquid of the water purification box 12 flows into the water outlet 113 from the liquid outlet hole 103 under the action of air pressure or water pressure. Figure 6 As shown, Figure 6It is a schematic diagram of the first embodiment of the water purification device of the present application, wherein the air supply hole 117 is provided in the cavity of the mounting seat 11, and the water purification box 12 is provided with a one-way valve 109 for delivering air pressure to the inside of the water purification box 12; the water purification box 12 is fixed in the cavity 110 in the positive direction, that is, when the descaling end 101 faces the bottom of the cavity 110, the air supply hole 117 is connected to the one-way valve 109, and air pressure is pumped into the one-way valve 109 through the air pump 18, and the descaling liquid in the water purification box 12 flows from the liquid outlet hole 103 to the water outlet 113 under the action of air pressure. The system innovatively combines the design of the air supply hole 117 of the mounting seat 11 with the one-way air pressure delivery valve structure of the descaling box 16. Specifically, air pressure is accurately pumped into the one-way valve 109 through the external air pump 18 device. This air pressure acts on the inside of the water purification box 12, driving the descaling liquid to flow smoothly from the preset liquid outlet 103 into the water outlet 113, thereby realizing the effective release and utilization of the descaling liquid. It is worth mentioning that the one-way valve 109 incorporates an anti-backflow mechanism: when the air pump 18 stops working, the one-way valve 109 can strictly prevent the descaling liquid from backflowing to the air replenishment hole 117, thereby effectively avoiding potential liquid leakage problems and ensuring the overall sealing and safety of the system. In summary, this embodiment, through the ingenious combination of the air replenishment hole 117 and the one-way air pressure delivery valve, not only realizes the precise release of the descaling liquid under the action of air pressure, but also further improves the stability and reliability of the system through the anti-backflow design of the one-way valve 109, providing a strong guarantee for the smooth progress of the descaling process.

[0079] In the third embodiment, the descaling liquid of the water purification box 12 flows into the water outlet 113 from the liquid outlet hole 103 under the action of air pressure or water pressure. Figure 7 As shown, Figure 7 It is a schematic diagram of the first embodiment of the water purification device of the present application replenishing water through a water pump. The cavity of the mounting seat 11 is provided with a water replenishing hole 118, and the water purification box 12 is provided with a one-way valve 109 for conveying water pressure to the inside of the water purification box 12; the water purification box 12 is fixed in the cavity 110 in the positive direction, that is, when the descaling end 101 is facing the bottom of the cavity 110, the water replenishing hole 118 is connected with the one-way valve 109, and water pressure is pumped into the one-way valve 109, and the descaling liquid in the water purification box 12 flows from the liquid outlet 103 to the water outlet 113 under the action of the water pressure. The design of the one-way valve 109 incorporates an anti-backflow mechanism: when the water pump 3 stops working, the one-way valve 109 can strictly prevent the descaling liquid from flowing back to the water replenishing hole 118, thereby avoiding the potential risk of liquid leakage and ensuring the overall sealing and safety of the system.

[0080] In order to intelligently identify whether the water purification box 12 is currently loaded with descaling liquid or filter material, refer to Figure 3 , Figure 8 and Fig. 9 As shown, Figure 8 Schematic diagram of Hall sensor in the first embodiment of the water purification device of the present application when installed in the forward direction. Fig. 9It is a schematic diagram of Hall induction in the first embodiment of the water purification device of the present application when it is installed in reverse. The water purification device 1 also includes a Hall induction component 15, which includes a Hall switch 151 and a magnet 152; the mounting seat 11 is provided with two Hall switches 151 at different positions, and the descaling end 101 and the scale prevention end 102 are provided with magnets 152 respectively; the water purification box 12 is fixed in the cavity 110 in the positive direction, that is, when the descaling end 101 is facing the bottom of the cavity 110, one of the Hall switches 151 is opposite to the magnet 152 on the water purification box 12 and senses; the water purification box 12 is fixed in the cavity 110 in the reverse direction, that is, when the scale prevention end 102 is facing the bottom of the cavity 110, the other Hall switch 151 is opposite to the magnet 152 on the water purification box 12 and senses. Both of these Hall switches 151 establish a close electrical connection with the control device, and they will feed back the generated induction signal to the control device in real time. After receiving these signals, the control device can identify the type of component currently installed and send corresponding control instructions accordingly. For example, the control device can drive the indicator light corresponding to the descaling or antiscaling function to light up, thereby intuitively displaying the current function type and providing users with convenient operation guidance and status feedback.

[0081] In order to solve the above technical problem of how to reduce space occupation and use cost, this embodiment provides a water purification device 1. Figures 10 to 12 As shown, Fig.10 This is an exploded view of the second embodiment of the water purification device of the present application. Fig.11 This is a schematic diagram of the second embodiment of the water purification device of the present application when the descaling component is installed. Fig.12 It is a schematic diagram of the second embodiment of the water purification device of the present application when the scale inhibition component is installed.

[0082] The water purification device 1 includes: a mounting base 11, a descaling component and a scale inhibition component. The mounting base 11 is provided with a cavity 110 for installing the descaling component and the scale inhibition component, and a water inlet 112 and a water outlet 113 connected to the cavity 110, and the connection and blocking between the water inlet 112 and the water outlet 113 are controlled by a switch valve 13. The descaling component includes a descaling box 16 for accommodating descaling liquid, and the descaling box 16 is provided with a liquid outlet 103 for outputting the descaling liquid. Among them, the descaling liquid can be an existing descaling liquid or a cleaning liquid and other liquids with the function of purifying water quality. The scale inhibition component includes a scale inhibition box 17 for accommodating filter material, and the scale inhibition box 17 is provided with an inlet 104 and an outlet 105. Among them, the cavity 110 is configured to accommodate and detachably fix the descaling box 16 or the scale inhibition box 17. When the descaling box 16 is fixed in the cavity 110, the switch valve 13 is opened, and the liquid outlet 103 is connected with the water outlet 113, so that the descaling liquid in the descaling box 16 can flow from the liquid outlet 103 into the water outlet 113 under the action of air pressure or water pressure; when the scale inhibition box 17 is fixed in the cavity 110, the switch valve 13 is closed, the inlet 104 is connected with the water inlet 112, and the outlet 105 is connected with the water outlet 113.

[0083] The working process of the water purification device 1 of the above technical solution is as follows: Fig.11 As shown, when it is necessary to clean the scale, the user first detachably fixes the descaling box 16 (containing descaling liquid) into the cavity 110 of the mounting seat 11. Then, the switch valve 13 is opened to establish a passage between the water inlet 112 and the water outlet 113. Under the action of air pressure or water pressure, the descaling liquid flows into the water outlet 113 through the liquid outlet hole 103 of the descaling box 16, and then enters the water system of the smart toilet to clean the scale. After the descaling liquid is used up, the descaling box 16 is disassembled and necessary cleaning or replacement is performed.

[0084] When water filtration is required, refer to Fig.12 As shown, the user removably fixes the scale-proof box 17 (with filter material inside) into the cavity 110 of the mounting seat 11. The switch valve 13 is in a closed state. At this time, the water inlet 112 is connected to the inlet 104 of the scale-proof box 17, and the outlet 105 of the scale-proof box 17 is connected to the water outlet 113. Water flows into the scale-proof box 17 through the water inlet 112, and after being filtered by the filter material, it flows out from the outlet 105, enters the water outlet 113, and finally enters the water system of the smart toilet. As time goes by, the filter material may gradually become saturated or fail. At this time, the scale-proof box 17 needs to be removed and replaced with a new filter material.

[0085] It can be seen that the water purification device 1 and the smart toilet of the above technical solution install and manage the descaling component and the scale inhibition component uniformly through the mounting seat 11. Specifically, the descaling box 16 and the scale inhibition box 17 are both detachably fixed in the cavity 110 of the mounting seat 11, so that there is no need to install these two components separately at different positions of the water system, thereby greatly saving space. At the same time, since it is no longer necessary to install the descaling component and the filtering component separately at different positions of the water system, the installation steps are simplified and the installation difficulty is reduced. It is also important that, through the control of the switch valve 13, when descaling is required, the descaling liquid in the descaling box 16 can flow into the water outlet 113; and when filtering and scale inhibition are required, the water flow is filtered through the scale inhibition box 17. This switching working principle enables the water purification device 1 to meet the two functional requirements of descaling and filtration, further simplifies the system structure, and improves the flexibility of use. Finally, the descaling component and the antiscaling component can be integrated on the mounting base 11 for use. Since the descaling box 16 and the antiscaling box 17 can be removed from the mounting base 11, it is convenient for the user to replace or clean them as needed, and there is no need to manufacture and purchase two independent and complete components separately, which not only saves space but also may reduce production costs to a certain extent.

[0086] In one embodiment, the connection and blocking between the water inlet 112 and the water outlet 113 is controlled by the switch valve 13, see Fig.11 and Fig.12As shown, the mounting seat 11 is provided with a valve cavity 114 between the water inlet 112 and the water outlet 113, and the valve cavity 114 is provided with a cavity 115 connected with the containing cavity 110; the switch valve 13 includes a valve core 131 and a spring 132, the valve core 131 is movably arranged in the valve cavity 114, and is used to control the connection and blocking between the water inlet 112 and the water outlet 113, that is, to open or close the connection between the water inlet 112 and the water outlet 113, and the spring 132 is arranged in the valve cavity 114 and is configured to drive The valve core 131 moves toward the cavity opening 115; the descaling box 16 is provided with a make way groove 120. When the descaling box 16 is fixed in the cavity 110, the valve core 131 passes through the cavity opening 115 driven by the spring 132 and extends into the make way groove 120 to connect the water inlet 112 and the water outlet 113; when the descaling box 16 is fixed in the cavity 110, the valve core 131 is pressed down by the scale inhibition box 17 to between the water inlet 112 and the water outlet 113 to block the water inlet 112 and the water outlet 113. In this embodiment, the switch valve 13 can not only control the connection and blockage between the water inlet 112 and the water outlet 113, but also the control operation can be automatically and adaptively performed according to the installation of the descaling box 16 and the scale inhibition box 17, that is, when the descaling box 16 is installed in the cavity 110, the valve core 131 is automatically opened under the drive of the spring 132 because the make way groove 120 can make way for the valve core 131, so that the water inlet 112 and the water outlet 113 are connected, and when the scale inhibition box 17 is installed in the cavity 110, the valve core 131 is pressed down by the scale inhibition box 17 against the elastic force of the spring 132, so that the water inlet 112 and the water outlet 113 are automatically blocked, and the water flow from the water inlet 112 can enter the scale inhibition box 17 for filtration.

[0087] For example, see Fig.10 and Fig.11 As shown, in order to facilitate the installation of the valve core 131 and the spring 132, the mounting seat 11 is provided with a port at one end of the valve cavity 114 away from the cavity opening 115, and a buckle cover 133 is provided on the port, and the buckle cover 133 is used to seal the port, and one end of the spring 132 abuts against the inner side of the buckle cover 133, and the other end abuts against the valve core 131. During installation, the valve core 131 and the spring 132 are sequentially installed into the valve cavity 114, and then the buckle cover 133 is used to seal the port, so that the spring 132 is compressed to drive the valve core 131 to move toward the cavity opening 115. Among them, the buckle cover 133 can be connected to the port by buckle or thread, and a sealing ring is provided between the buckle cover 133 and the port to achieve the sealing of the port and prevent water from flowing out.

[0088] In order to limit the maximum movement of the valve core 131 toward the cavity 115, refer to Fig.11 As shown, the valve core 131 is provided with a shoulder structure. When the descaling box 16 is fixed in the cavity 110 , the shoulder abuts against the edge of the cavity opening 115 , thereby limiting the valve core 131 from further moving toward the cavity opening 115 .

[0089] It is understandable that the valve core 131 and the spring 132 can also be installed into the valve cavity 114 from the cavity opening 115 . At this time, the end of the mounting seat 11 at the valve cavity 114 away from the cavity opening 115 can be a sealing structure integrally formed with the mounting seat 11 .

[0090] In another embodiment (not shown) in which the connection and blocking between the water inlet 112 and the water outlet 113 are controlled by the switch valve 13, the switch valve 13 is an electronic valve and is provided with a control button, and the control button is triggered by the descaling box 16 and the anti-scaling box 17, thereby controlling the switch of the switch valve 13. Exemplarily, when the descaling box 16 is fixed in the cavity 110, the descaling box 16 presses down and triggers the control button, so that the switch valve 13 is opened, and the water inlet 112 and the water outlet 113 are connected; when the anti-scaling box 17 is fixed in the cavity 110, the anti-scaling box 17 cannot trigger the control button, the switch valve 13 remains closed, and the water inlet 112 and the water outlet 113 are blocked.

[0091] In order to realize rapid positioning with the mounting seat 11 when the descaling box 16 and the antiscaling box 17 are installed in the cavity 110, refer to Fig.10 As shown, the outer side of the descaling box 16 and the antiscaling box 17 is provided with a guide rib 106 extending in the length direction, and the inner side of the mounting seat 11 is provided with a guide groove 116 adapted to the guide rib 106; when the descaling box 16 or the antiscaling box 17 is fixed in the cavity 110, the guide rib 106 is located in the guide groove 116, and the descaling box 16 or the antiscaling box 17 is circumferentially fixed to the mounting seat 11, so that the liquid outlet 103 and the water outlet 113 are located opposite and connected, or the inlet 104 and the water inlet 112 are located opposite and connected, and the outlet 105 and the water outlet 113 are located opposite and connected. With such a configuration, when the descaling box 16 and the antiscaling box 17 are installed, it is only necessary to ensure that the guide rib 106 is located in the guide groove 116, and the cooperation of the guide rib 106 and the guide groove 116 plays a foolproof role.

[0092] It is understandable that the descaling box 16 and the antiscaling box 17 can also be quickly positioned on the mounting seat 11 by means of marking lines. Exemplarily, the descaling box 16 and the antiscaling box 17 are provided with marking lines on the top of the mounting seat 11. When the marking lines of the descaling box 16 and the antiscaling box 17 are positioned relative to the marking lines of the mounting seat 11, the liquid outlet 103 and the water outlet 113 are positioned relative to and connected to each other, or the inlet 104 and the water inlet 112 are positioned relative to and connected to each other, and the outlet 105 and the water outlet 113 are positioned relative to and connected to each other.

[0093] In one embodiment of the above-mentioned chamber 110, the descaling box 16 or the antiscaling box 17 can be detachably fixed. Figures 10 to 12As shown, the water purification device 1 further includes a rotating cover 14, and the top of the mounting seat 11 is open. When the descaling box 16 or the scale-preventing box 17 is loaded on the top of the mounting seat 11 and fixed in the cavity 110, the rotating cover 14 is connected to the mounting seat 11 through a rotating buckle 141 to be fixed relative to the mounting seat 11. The rotating cover 14 is pressed on the descaling box 16 or the scale-preventing box 17 to fix the relative position of the descaling box 16 or the scale-preventing box 17 and the mounting seat 11. When disassembling the descaling box 16 or the scale-preventing box 17, it is only necessary to rotate the rotating cover 14 in the opposite direction to disengage the rotating buckle 141, so that the cavity 110 can be opened and the descaling box 16 or the scale-preventing box 17 can be taken out.

[0094] For example, see Fig.10 As shown, the rotating cover 14 and the descaling box 16 are connected by a strong release buckle 142 to improve the firmness of the connection.

[0095] The rotating cover 14 can also be connected to the mounting seat 11 by means of threaded connection or tight connection, so that it can be fixed relative to the mounting seat 11 and opened when the descaling box 16 or the antiscaling box 17 is disassembled.

[0096] In other embodiments in which the above-mentioned cavity 110 can detachably fix the descaling box 16 or the antiscaling box 17, the descaling box 16 and the antiscaling box 17 are directly connected to the mounting seat 11 by threads or snaps, and an end cover is provided on the top, and the cavity 110 is sealed by the end cover when connected.

[0097] In order to add descaling liquid to the descaling box 16, refer to Fig.10 As shown, the descaling box 16 is provided with an opening, and a sealing cover 107 is provided at the opening, and the sealing cover 107 is used to prevent the descaling liquid from leaking out.

[0098] In the first embodiment, the descaling liquid in the descaling box 16 flows into the water outlet 113 from the liquid outlet 103 under the action of air pressure or water pressure. Fig.11 As shown, the sealing cover 107 is provided with a one-way air inlet valve 108 for conveying air pressure to the inside of the descaling box 16, and the rotating cover 14 is provided with an air inlet hole 143 for conveying air pressure to the one-way air inlet valve 108; the water flow section of the water outlet 113 at the place where it is connected with the liquid outlet hole 103 first decreases and then increases along the water flow direction. When the descaling box 16 is fixed in the cavity 110, in the initial state, the descaling liquid cannot or can only flow out of the liquid outlet hole 103 in a small amount due to insufficient pressure; when the water flows from the water inlet 112 to the water outlet 113, and the water flows through the connection where the water flow section first decreases and then increases along the water flow direction, the descaling liquid in the descaling box 16 is sucked into the water outlet 113 from the liquid outlet hole 103 under the action of the Bernoulli principle, and mixed with the water flow, thereby playing a role in purifying scale and dirt. Subsequently, the one-way air inlet valve 108 inhales air to balance the air pressure inside the descaling box 16.

[0099] In the second embodiment, the descaling liquid in the descaling box 16 flows into the water outlet 113 from the liquid outlet 103 under the action of air pressure or water pressure. Fig.13 and Fig.14 As shown, Fig.13 This is a schematic diagram of the second embodiment of the water purification device of the present application, in which air is replenished by an air pump. Fig.14 It is a three-dimensional diagram of the second embodiment of the water purification device of the present application, which is replenished with air through an air pump. The cavity of the mounting seat 11 is provided with an air replenishment hole 117, and the descaling box 16 is provided with a one-way valve 109 for conveying air pressure into the descaling box 16; when the descaling box 16 is fixed in the cavity 110, the air replenishment hole 117 is connected with the one-way valve 109, and air pressure is pumped into the one-way valve 109 through the air pump 18, and the descaling liquid in the descaling box 16 flows from the liquid outlet 103 into the water outlet 113 under the action of air pressure. Among them, the one-way valve 109 can prevent the descaling liquid from flowing out of the air replenishment hole 117 when the air pump 18 is not working.

[0100] In the third embodiment, the descaling liquid in the descaling box 16 flows into the water outlet 113 from the liquid outlet hole 103 under the action of air pressure or water pressure. Fig.15 and Fig.16 As shown, Fig.15 It is a schematic diagram of the second embodiment of the water purification device of the present application replenishing water through a water pump; Fig.16 It is a stereoscopic diagram of the second embodiment of the water purification device of the present application, which is replenished with air through an air pump. The cavity of the mounting seat 11 is provided with a water replenishment hole 118, and the descaling box 16 is provided with a one-way valve 109 for delivering water pressure to the inside of the descaling box 16; when the descaling box 16 is fixed in the cavity 110, the water replenishment hole 118 is connected with the one-way valve 109, and water pressure is pumped into the one-way valve 109 through the water pump 3, and the descaling liquid in the descaling box 16 flows from the liquid outlet 103 to the water outlet 113 under the action of the water pressure. Among them, the one-way valve 109 can prevent the descaling liquid from flowing out of the water replenishment hole 118 when the water pump 3 is not working. The water pump 3 has two functions, which can add water to the water inlet and add water to the descaling box 16, thereby one machine has multiple uses, thereby simplifying the product structure and reducing costs.

[0101] In order to automatically sense whether the descaling component or the antiscaling component is installed in the mounting seat 11, refer to Fig.17 and Fig.18 As shown, Fig.17 It is a schematic diagram of Hall induction in the first embodiment of the water purification device of the present application when installed in the forward direction; Fig.18It is a schematic diagram of Hall induction in the reverse installation of the first embodiment of the water purification device of the present application. The water purification device 1 also includes a Hall induction component 15, and the Hall induction component 15 includes a Hall switch 151 and a magnet 152; two Hall switches 151 are provided on the mounting seat 11, and the descaling box 16 and the scale prevention box 17 are provided with magnets 152; when the descaling box 16 is fixed in the cavity 110, the magnet 152 on the descaling box 16 is opposite to one of the Hall switches 151 and senses, and the Hall switch 151 generates a sensing signal of the descaling component; when the scale prevention box 17 is fixed in the cavity 110, the magnet 152 on the scale prevention box 17 is opposite to another Hall switch 151 and senses, and the Hall switch 151 generates a sensing signal of the scale prevention component. The Hall switch 151 is connected to the control device and feeds back the sensing signal to the control device. The control device can send a control instruction according to the sensing signal of the descaling component or the scale prevention component, such as controlling the corresponding indicator light to light up to display the type of component currently installed.

[0102] It is understandable that two water purification devices 1 can be arranged between the water pump 3 and the water outlet assembly, see Fig.19 As shown, Fig.19 It is a schematic diagram of an intelligent toilet provided with two water purification devices in an embodiment of the present application. The two water purification devices 1 can be any one of the above two embodiments, and are connected in sequence, and the two water purification devices 1 are respectively provided with a descaling component and a scale prevention component. Exemplarily, the former water purification device 1 is provided with a scale prevention component, and its water inlet 112 is connected to the water pump 3, and the water outlet (drain 111 or water outlet 113) is connected to the water inlet 112 of the latter water purification device 1, and the latter water purification device 1 is provided with a descaling component, and its water outlet (drain 111 or water outlet 113) supplies water to the rear-end components such as the instant heater 5 and the spray rod 4. With such a configuration, the water circuit of the intelligent toilet can simultaneously realize the scale prevention and descaling functions through the connecting rod water purification device 1, further improve the water quality of the water used, and enhance the user experience.
