Description

TECHNICAL FIELD

[0001] The present application relates to the field of bathroom, in particular to a dual-purpose water purification mechanism and an intelligent toilet. BACKGROUND

[0002] In order to optimize water quality, bathroom products such as intelligent toilets generally use descaling liquid and filter materials to remove scale and various impurities in water. However, the descaling liquid and filter material products on the current market are mostly designed as independent units and are respectively configured in different carriers. In the actual installation process, if the functions of the descaling liquid and the filter material are to be utilized, the carriers to which they respectively belong must be installed at different positions of the waterway system of the intelligent toilet. This scattered and independent configuration of the descaling liquid and the filter material not only occupies a large amount of installation space, increasing the difficulty of bathroom space layout, but also requires the user to separately purchase two types of carriers when purchasing and subsequently replacing, which undoubtedly increases the use cost and reduces the overall economy and convenience.

[0003] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. CONTENT OF THE UTILITY MODEL

[0005] The embodiments of the present application provide a dual-purpose water purification mechanism and an intelligent toilet, which can solve the problem of how to reduce the occupied space and use cost in the prior art.

[0006] (II) Technical solutions

[0007] To solve the above technical problems, the present application provides the following technical solutions:

[0008] A dual-purpose water purification mechanism is provided, which is arranged on a water flow pipeline of a water-using device, comprising: a mounting seat and a water purification assembly;

[0009] The mounting seat is provided with a cavity and a switch valve, the cavity is provided with a water inlet, a water outlet and a drain, and the switch valve is used to control the flow and block of water between the water inlet and the water outlet;

[0013] In some embodiments, the mounting base has a port at the end of the valve cavity opposite to the cavity opening, and a cover is provided on the port for sealing the port. One end of the spring abuts against the inner side of the cover, and the other end abuts against the valve core.

[0014] In some embodiments, the outer side of the water purification box is provided with guide ribs extending along the length direction, and the inner side of the mounting base is provided with guide grooves adapted to the guide ribs; when the water purification box is fixed in the cavity, the guide ribs are located in the guide grooves, and the water purification box and the mounting base are circumferentially fixed so that the liquid outlet is opposite to and connected to the water outlet, or the inlet is opposite to and connected to the water inlet, and the outlet is opposite to and connected to the water outlet.

[0015] In some embodiments, the dual-purpose water purification mechanism further includes a rotating cover, which is connected to the mounting base by a rotating snap and pressed onto the water purification box, so that the water purification box and the mounting base are fixed in the cavity.

[0016] In some embodiments, the water purification box has an opening and a sealing cover at the opening. The sealing cover has a one-way air inlet valve for supplying air pressure to the interior of the water purification box, and the rotating cover has an air inlet for supplying air pressure to the one-way air inlet valve. The water flow cross-section at the outlet where it communicates with the liquid outlet first decreases and then increases along the water flow direction. When the water purification box is fixed in the cavity, the descaling liquid in the water purification box flows into the outlet from the liquid outlet under the action of Bernoulli's principle.

[0017] In some embodiments, the mounting base is provided with an air inlet, and the water purification box is provided with a one-way valve for supplying air pressure into the water purification box; when the water purification box is fixed in the cavity, the air inlet is connected to the one-way valve, and air pressure is pumped into the one-way valve through an air pump, and the descaling liquid in the water purification box flows into the water outlet from the liquid outlet under the action of air pressure.

[0018] In some embodiments, the mounting base is provided with a water inlet hole, and the water purification box is provided with a one-way valve for supplying water pressure to the inside of the water purification box; when the water purification box is fixed in the cavity, the water inlet hole is connected to the one-way valve and water pressure is pumped into the one-way valve, and the descaling liquid in the water purification box flows into the water outlet from the liquid outlet hole under the action of water pressure.

[0019] In some embodiments, the dual-purpose water purification mechanism further includes a Hall effect sensor assembly, which includes a Hall effect switch and a magnet; the mounting base is provided with two Hall effect switches at different positions, and the water purification box is provided with magnets at its forward and reverse ends respectively; when the water purification box is fixed in the forward direction within the cavity, one of the Hall effect switches is positioned opposite to and senses the magnet on the water purification box; when the water purification box is fixed in the reverse direction within the cavity, the other Hall effect switch is positioned opposite to and senses the magnet on the water purification box.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

[0023] The dual-purpose water purification mechanism and smart toilet of this application use a water purification box to hold descaling solution and filter media separately or simultaneously. When descaling solution and filter media are needed, they only need to be placed into the water purification box for use, without the need to install their respective carriers into different parts of the smart toilet's water circuit system as in existing technologies. This effectively reduces space occupation and improves the utilization efficiency of bathroom space. Equally important, users do not need to purchase descaling solution and filter media carriers separately, thus saving equipment purchase costs. At the same time, the water purification box is detachable and reusable. Users only need to replace the internal descaling solution or filter media periodically, without replacing the entire device, which greatly reduces long-term operating costs. It can be seen that the dual-purpose water purification mechanism and smart toilet of this application can effectively reduce space occupation and operating costs, and improve user experience.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] To improve water quality, bathroom products such as smart toilets typically use descaling solutions and filter media to remove scale and impurities from the water. However, most descaling solutions and filter media on the market are currently installed separately in different products. In practical applications, if both descaling solutions and filter media are needed simultaneously, these products must be installed in different locations within the smart toilet's water system. This independent and dispersed installation of descaling solutions and filter media occupies considerable installation space. Furthermore, the cost of using descaling solutions and filter media is relatively high because they need to be purchased and replaced separately.

[0041] To address the aforementioned technical problems, this embodiment provides a dual-purpose water purification mechanism, see reference. Figures 1 to 3 As shown, Figure 1 This is an exploded view of the dual-purpose water purification mechanism of this application. Figure 2 This is a cross-sectional view of the dual-purpose water purification mechanism of this application during forward installation. Figure 3 This is a cross-sectional view of the dual-purpose water purification mechanism of this application when installed in reverse.

[0042] The dual-purpose water purification mechanism of this embodiment is used to be installed on the water flow pipeline of the water-using equipment, and includes: a mounting base 11 and a water purification component.

[0043] The mounting base 11 is provided with a cavity 110 and a switch valve 13. The cavity 110 is provided with a drain outlet 111, and the bottom is provided with a water inlet 112 and a water outlet 113. The water inlet 112 and the water outlet 113 are connected and blocked by the switch valve 13.

[0044] The water purification assembly includes a water purification box 12 for holding descaling solution or filter media. The water purification box 12 has a descaling end 101 and a scale-blocking end 102. The descaling end 101 has an outlet hole 103 for discharging descaling solution and a water outlet 105. The scale-blocking end 102 has a water inlet 104. The water purification box 12 also has a water drain outlet 111. The descaling solution can be any existing descaling solution or cleaning solution, or other liquid with water purification function.

[0045] The water purification box 12 is detachably connected to the mounting base 11 and can be fixed in the cavity 110 in either the forward or reverse direction, i.e., the descaling end 101 or the scale-blocking end 102 faces the bottom of the cavity 110. When the water purification box 12 is fixed in the forward direction, i.e., when the descaling end 101 faces the bottom of the cavity 110, the switch valve 13 is opened, and the liquid outlet 103 is connected to the water outlet 113, so that the descaling liquid in the water purification box 12 can flow from the liquid outlet 103 to the water outlet 113 under the action of air pressure or water pressure. When the water purification box 12 is fixed in the reverse direction, i.e., when the scale-blocking end 102 faces the bottom of the cavity 110, the switch valve 13 is closed, the inlet 104 is connected to the water inlet 112, and the outlet 105 is connected to the drain outlet 111.

[0046] For example, see Figure 3 As shown, the water purification box 12 is fixed in reverse inside the cavity 110, that is, when the scale-inhibiting end 102 faces the bottom of the cavity 110, a drainage channel is formed between the water purification box 12 and the mounting base 11, connecting the outlet 105 and the drain outlet 111.

[0047] It is understandable that the outlet 105 can also be located in other positions, such as at the scale-inhibiting end 102, offset from the inlet 104, while the drain outlet 111 is located at the bottom of the mounting base 11.

[0048] The descaling process of the dual-purpose water purification mechanism in the above technical solutions is as follows: (See attached document) Figure 2As shown, the process begins with the following steps: First, in the preparation stage, ensure that the water purifier box 12 is filled with an appropriate amount of descaling solution; align the descaling end 101 of the water purifier box 12 with the bottom of the cavity 110 and ensure it is securely fixed. Then, in the startup stage, open the switch valve 13 to establish a passage between the inlet 112 and the outlet 113; under air or water pressure, the descaling solution flows into the outlet 113 through the outlet hole 103 of the descaling end 101. Finally, in the operation stage, the descaling solution continuously flows out from the outlet hole 103, entering the smart toilet water system or other devices requiring descaling, thus achieving the descaling function. During use, the water purifier box 12 can be disassembled as needed for cleaning or replacement with new descaling solution.

[0049] The scale inhibition / purification process of the dual-purpose water purification mechanism in the above technical solution is as follows: (See attached document) Figure 3 As shown, the process is as follows: First, in the preparation stage: confirm that an appropriate amount of filter media (such as activated carbon, ultrafiltration membrane, etc.) is loaded into the water purification box 12; then, align the scale-blocking end 102 of the water purification box 12 with the bottom of the cavity 110 and ensure it is securely fixed. Next is the startup stage: close the switch valve 13, ensuring that the inlet 112 is connected to the water inlet 104 of the scale-blocking end 102, and the outlet 111 is connected to the water outlet 105 of the scale-blocking end 102. Finally, in the operation stage: water flows through the inlet 112 into the water inlet 104 of the scale-blocking end 102; the water is filtered by the filter media, removing impurities, microorganisms, etc.; the filtered clean water flows out from the outlet 105, enters the outlet 111, and finally enters the smart toilet water system or other devices requiring water purification. During use, the water purification box 12 should be disassembled periodically and the filter media replaced with new ones, depending on the lifespan and filtration effect of the filter media.

[0050] The dual-purpose water purification mechanism and smart toilet described above use a water purification box 12 to hold descaling solution and filter media, either individually or simultaneously. When descaling solution and filter media are needed, they can simply be placed inside the water purification box 12, eliminating the need for separate installation of their respective carriers into different parts of the smart toilet's water system, as required by existing technologies. This effectively reduces space occupancy and improves the utilization efficiency of bathroom space. Equally important, users do not need to purchase separate carriers for descaling solution and filter media, thus saving on equipment purchase costs. Furthermore, the water purification box 12 is detachable and reusable; users only need to periodically replace the internal descaling solution or filter media, without replacing the entire device, significantly reducing long-term operating costs. It can be seen that the dual-purpose water purification mechanism and smart toilet described above effectively reduce space occupation and operating costs, while enhancing the user experience.

[0051] In one embodiment where the connection and disconnection between the aforementioned inlet 112 and outlet 113 are controlled by a switching valve 13, see [reference needed]. Figure 1 and Figure 2As shown, the mounting base 11 has a valve chamber 114 between the inlet 112 and the outlet 113, and the valve chamber 114 has a cavity 115 communicating with the cavity 110; the switching valve 13 includes a valve core 131 and a spring 132. The valve core 131 is movably disposed in the valve chamber 114 and is used to control the connection and disconnection between the inlet 112 and the outlet 113. The spring 132 is disposed in the valve chamber 114 and is configured to drive the valve core 131 to move towards the cavity 115; the descaling end 101 has a relief groove 120, which allows for the cleaning of the descaling end. The water box 12 is fixed in the forward direction within the cavity 110. When the descaling end 101 faces the bottom of the cavity 110, the valve core 131, driven by the spring 132, passes through the cavity opening 115 and extends into the relief groove 120 to connect the inlet 112 and the outlet 113. The purified water box 12 is fixed in the reverse direction within the cavity 110. When the scale-inhibiting end 102 faces the bottom of the cavity 110, the valve core 131 is pressed down by the purified water box 12 between the inlet 112 and the outlet 113 to block the flow between them. In this embodiment, the switching valve 13 not only controls the flow between the inlet 112 and the outlet 113 but also incorporates an automated and adaptive control mechanism. Its operating logic can automatically respond to the installation status of the purified water box 12. Specifically, when the water purification box 12 is installed with the descaling end 101 facing the bottom of the cavity 110, the clearance groove 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 inlet 112 and the outlet 113. Conversely, when the water purification box 12 is installed with the scale inhibition end 102 facing the bottom of the cavity 110, its structural characteristics effectively resist the elastic force of the spring 132 and press down the valve core 131, causing the inlet 112 and the outlet 113 to automatically close. At this time, the water flow from the inlet 112 is guided into the scale inhibition box 17 for necessary filtration. This design not only improves the ease of operation of the equipment but also significantly enhances the flexibility and intelligence of the system.

[0052] For example, the water purification box 12 includes two mutually separated inner cavities (not shown in the figure), which are separated by a partition and respectively provided with a descaling end 101 and a scale-blocking end 102, which can be used to hold descaling liquid and filter media, respectively. In this way, a water purification box 12 can simultaneously have descaling and filtration functions. When using it, you only need to select the end with the corresponding function and insert it into the cavity 110. It is convenient to use and further simplifies the product structure and reduces the cost of use.

[0053] Furthermore, to optimize the installation process of valve core 131 and spring 132, please refer to... Figure 4As shown, a port can be opened at the end of the valve cavity 114 of the mounting base 11 away from the cavity opening 115. A cover 133 is fitted on this port, the main function of which is to seal the port and support the spring 132. The design of the cover 133 allows one end of the spring 132 to rest against its inner side, while the other end of the spring 132 supports the valve core 131. During 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 seal the port with the cover 133. This action not only completes the installation, but also compresses the spring 132 to move the valve core 131 toward the cavity opening 115, achieving the expected pre-tightening state. The connection between the cover 133 and the port can be either a convenient snap-fit ​​connection or a stable threaded connection, ensuring the firmness of the cover 133. In addition, to prevent water from seeping out through the gap, a sealing ring is also provided between the 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 process, but also ensures the overall performance and reliability of the equipment through precise design.

[0054] To ensure that the valve core 131 does not exceed the predetermined maximum stroke when moving toward the cavity 115, refer to Figure 2 and Figure 3 As shown, the valve core 131 in this embodiment is provided with a shoulder structure. When the descaling box 16 is securely installed in the cavity 110, the shoulder structure will make effective contact with the edge of the cavity opening 115, thereby restricting the valve core 131 from moving further towards the cavity opening 115.

[0055] Understandably, see Figure 2 and Figure 3 As shown, the assembly process of valve core 131 and spring 132 can also be completed through the aforementioned cavity 115. In this case, the mounting base 11 adopts a sealing structure integrally formed with the mounting base 11 itself at the end of valve cavity 114 away from cavity 115. This not only simplifies the structure but also further enhances the sealing performance, ensuring the integrity of the inside of valve cavity 114 and the efficiency of water flow processing.

[0056] In another embodiment (not shown) where the connection and disconnection between the inlet 112 and outlet 113 are controlled by a switching valve 13, the connection and disconnection between the inlet 112 and outlet 113 are controlled by an electronic valve acting as the switching valve 13. The electronic valve is equipped with a control button, and its operating state intelligently responds to the installation status of the descaling box 16 and the scale inhibition box 17. Specifically, when the descaling end 101 faces the bottom of the cavity 110, it presses down and activates the control button, thereby triggering the electronic valve to open, establishing a smooth connection path between the inlet 112 and outlet 113. Conversely, if the scale inhibition end 102 faces the bottom of the cavity 110, due to its design with a clearance structure similar to the clearance groove 120, it cannot trigger the control button, and the electronic valve remains closed, effectively blocking the water flow between the inlet 112 and outlet 113. This implementation method allows the electronic valve to automatically adjust its operating state by precisely sensing the different installation conditions of the descaling end 101 and the scale inhibition end 102, thereby ensuring the accuracy of water flow control and the stability of system operation.

[0057] To facilitate the installation of the water purification box 12, the descaling end 101 and the scale inhibition end 102 are located at opposite ends of the length of the water purification box 12, making their functions easily distinguishable. (See reference...) Figure 1 As shown, guide ribs 106 are provided along the length of the outer surface of the water purification box 12, while the inner side of the mounting base 11 is equipped with guide grooves 116 that match these guide ribs 106. When the water purification box 12 is installed, the guide ribs 106 will naturally slide into the guide grooves 116. This not only simplifies the installation process but also ensures the accuracy of the installation. At the same time, it achieves circumferential fixation between the water purification box 12 and the mounting base 11, so that the liquid outlet 103 on the water purification box 12 can be precisely aligned with the water outlet 113 and connected. Alternatively, when the scale-inhibiting end 102 is facing down, the inlet 104 of the water purification box 12 is aligned with the water inlet 112 and connected, while the outlet 105 is also connected with the drain outlet 111. It is particularly worth mentioning that the ingenious cooperation between the guide ribs 106 and the guide grooves 116 not only guides the installation but also has a foolproof function, effectively avoiding installation errors and ensuring that the water purification box 12 can be installed accurately.

[0058] It is understandable that the descaling box 16 and the scale inhibition box 17 can also be quickly positioned on the mounting base 11 using marking lines. For example, the descaling box 16 and the scale inhibition box 17 are mounted on the mounting base 11 with marking lines on the top. When the marking lines of the descaling box 16 and the scale inhibition box 17 are aligned with the marking lines of the mounting base 11, the liquid outlet 103 is aligned with and connected to the water outlet 113, or the inlet 104 is aligned with and connected to the water inlet 112, and the outlet 105 is aligned with and connected to the drain outlet 111.

[0059] In one embodiment where the water purification box 12 can be fixed in the cavity 110 in either the forward or reverse direction, see [reference]. Figure 1 , Figure 2 and Figure 3 As shown, the dual-purpose water purification mechanism also includes a rotating cover 14, which is connected to the mounting base 11 via a rotating snap fastener 141 and pressed onto the water purification box 12, thereby fixing the water purification box 12 and the mounting base 11 within the cavity 110. When disassembling the descaling box 16 or the scale inhibition box 17, simply rotate the rotating cover 14 in the opposite direction to disengage the rotating snap fastener 141, thus opening the cavity 110 and removing the descaling box 16 or the scale inhibition box 17.

[0060] For example, see Figure 1 As shown, the rotating cover 14 and the water purification box 12 are connected by a strong release buckle 142 to enhance the connection's firmness.

[0061] The rotating cover 14 can also be connected to the mounting base 11 by means of threaded connection or tight connection, so that it can be fixed relative to the mounting base 11 and opened when the descaling box 16 or scale inhibition box 17 is disassembled.

[0062] In other embodiments where the cavity 110 is detachably fixed to the descaling box 16 or the scale inhibition box 17, the descaling box 16 and the scale inhibition box 17 are directly connected to the mounting base 11 by threads or snap-fit, and are provided with end caps at the top. When connected, the cavity 110 is sealed by the end caps.

[0063] To facilitate identification of the descaling end 101 and the scale inhibition end 102, and to facilitate the addition of descaling solution to the descaling box 16, please refer to... Figure 1 and Figure 2 As shown, the water purification box 12 has an opening and a sealing cover 107 at the opening, which can prevent the descaling liquid from leaking out.

[0064] In the first embodiment, under the action of air pressure or water pressure, the descaling solution in the water purification box 12 flows from the liquid outlet 103 into the water outlet 113. See [reference needed] Figure 2As shown, the sealing cover 107 is equipped with a one-way air inlet valve 108 for supplying air pressure to the interior of the water purification box 12, and the rotating cover 14 is equipped with an air inlet hole 143 for supplying air pressure to the one-way air inlet valve 108. The water flow cross-section at the outlet 113, where it connects with the liquid outlet 103, first decreases and then increases along the water flow direction. The water purification box 12 is fixed in the cavity 110, meaning that when the descaling end 101 faces the bottom of the cavity 110, the descaling liquid in the water purification box 12 flows into the outlet 113 from the liquid outlet 103 under the action of Bernoulli's principle. When the water purification box 12 is installed inside the cavity 110, in its initial state, due to insufficient pressure, the descaling liquid cannot be released freely or can only be released in a small amount through the liquid outlet 103. As the water flows smoothly from the inlet 112 to the outlet 113, it encounters a connecting area where the water flow cross-section first decreases along the water flow direction and then gradually expands. This unique change in water flow cross-section cleverly utilizes Bernoulli's principle: in the region where increased flow velocity (decreased cross-section) leads to decreased pressure, the descaling solution in the descaling box 16 is effectively attracted and drawn out from the outlet 103, thus mixing with the mainstream water flow and achieving water purification. Subsequently, to maintain the internal pressure balance of the descaling box 16, the system's built-in one-way air inlet valve 108 activates in a timely manner, drawing in outside air and effectively compensating for any negative pressure that may arise from the release of the descaling solution. In summary, this implementation method achieves automatic utilization of the descaling solution and water purification through water flow dynamics and a pressure balance mechanism.

[0065] In the second embodiment, the descaling solution in the water purification box 12 flows from the outlet hole 103 into the outlet 113 under air pressure or water pressure. See [reference needed] Figure 4 As shown, Figure 4This is a schematic diagram of the dual-purpose water purification mechanism of this application, which is replenished with air via an air pump. The mounting base 11 is provided with an air replenishment hole 117, and the water purification box 12 is provided with a one-way valve 109 for supplying air pressure into the water purification box 12. The water purification box 12 is fixed in the upright position within the cavity 110, that is, when the descaling end 101 faces the bottom of the cavity 110, the air replenishment 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. Under the action of air pressure, the descaling liquid in the water purification box 12 flows from the liquid outlet 103 into the water outlet 113. The system innovatively combines the design of the air replenishment hole 117 of the mounting base 11 with the one-way air pressure supply valve structure of the descaling box 16. Specifically, an external air pump 18 precisely pumps air pressure into the one-way valve 109. This air pressure acts inside the water purification box 12, driving the descaling solution to flow smoothly from the preset outlet 103 into the outlet 113, achieving effective release and utilization of the descaling solution. 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 strictly prevents the descaling solution from flowing back to the air supply port 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 supply port 117 and the one-way air pressure delivery valve, not only achieves precise release of the descaling solution under 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.

[0066] In the third embodiment, the descaling solution in the water purification box 12 flows from the outlet hole 103 into the outlet 113 under air pressure or water pressure. See [reference needed] Figure 5 As shown, Figure 5 This is a schematic diagram of the dual-purpose water purification mechanism of this application, where water is replenished by a water pump. The mounting base 11 is provided with a water replenishment hole 118, and the water purification box 12 is provided with a one-way valve 109 for supplying water pressure to the inside of the water purification box 12. The water purification box 12 is fixed in the upright position inside the cavity 110, that is, when the descaling end 101 faces the bottom of the cavity 110, the water replenishment hole 118 is connected to the one-way valve 109, and water pressure is pumped into the one-way valve 109. Under the action of water pressure, the descaling liquid in the water purification box 12 flows from the liquid outlet 103 into the water outlet 113. 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 replenishment hole 118, thereby avoiding the potential risk of liquid leakage and ensuring the overall sealing and safety of the system.

[0067] To intelligently identify whether the water purifier box 12 is currently filled with descaling solution or filter media, please refer to... Figure 1 , Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of Hall effect sensing in the dual-purpose water purification mechanism of this application during forward installation. Figure 7This is a schematic diagram of Hall effect sensing in the dual-purpose water purification mechanism of this application when installed in reverse. The dual-purpose water purification mechanism also includes a Hall effect sensing component 15, which includes a Hall switch 151 and a magnet 152. The mounting base 11 has two Hall switches 151 at different positions, and magnets 152 are respectively provided at the descaling end 101 and the scale-inhibiting end 102. The purified water box 12 is fixed in the forward direction within the cavity 110, that is, when the descaling end 101 faces the bottom of the cavity 110, one of the Hall switches 151 is aligned with and senses the magnet 152 on the purified water box 12. When the purified water box 12 is fixed in reverse direction within the cavity 110, that is, when the scale-inhibiting end 102 faces the bottom of the cavity 110, the other Hall switch 151 is aligned with and senses the magnet 152 on the purified water box 12. Both Hall switches 151 are electrically connected to the control device, and they will feed back the generated sensing signals to the control device in real time. Upon receiving these signals, the control device can identify the type of currently installed component and send corresponding control commands. For example, the control device can activate indicator lights corresponding to descaling or scale inhibition functions, thus intuitively displaying the current function type and providing users with convenient operation guidance and status feedback.
