Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, specifically providing a water receiving component for a water purification equipment and a drainage control method for a water purification equipment. Background Technology

[0002] A water purifier is a device that filters tap water and other raw water to produce pure water, which is then discharged from the spout for user consumption. However, dripping or leaking water is common at the spout. Therefore, a drip tray is usually installed below the spout to collect any leaking water. When the water in the drip tray reaches a certain level, it needs to be cleared. Therefore, the drip tray can be designed to be detachable, allowing the user to remove it and empty the water when the water level reaches a certain point. Alternatively, the water in the drip tray can be diverted to another location, preventing overflow and eliminating the need for the user to remove and clean the tray.

[0003] In practical applications, whether it's an automatic drainage system or a water tray that needs to be removed for emptying, the tray is usually equipped with a level detection device to monitor the water level. This device provides an early warning when the water level reaches a certain height, reminding the user to remove the tray for emptying or to activate the automatic drainage program. These level detection devices are typically quite large, requiring significant installation space. Furthermore, automatic drainage trays often require two level detection devices to detect both low and high levels, increasing the cost of the tray and the space occupied by the water purification equipment. This increases the overall size and cost of the water purification system and also makes it more susceptible to detection errors.

[0004] Accordingly, a new technical solution is needed in this field to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems that existing water receiving trays increase the size and cost of water purification equipment to a certain extent, and that the accuracy of liquid level detection is not high enough, resulting in errors.

[0006] In a first aspect, the present invention provides a water receiving assembly for a water purification device, the water receiving assembly comprising: a water receiving tray having a water receiving cavity with a top opening; a support plate connected to the water receiving tray for supporting a water receiving container, the support plate having a plurality of drainage holes; and a sensing assembly comprising a water level sensing capacitor mounted on the cavity wall of the water receiving cavity.

A connecting pipe is provided on the side wall of the connector, and the connecting pipe connects the internal space of the connector to the water receiving cavity. The water level sensing capacitor is located in the internal space of the connector and is installed on the bottom wall of the connector.

[0008] In the preferred embodiment of the water receiving component for the water purification equipment described above, the water level sensing capacitor is set horizontally.

[0009] In the preferred embodiment of the water receiving assembly for the water purification equipment described above, a recessed mounting cavity is provided on the bottom wall of the water receiving cavity, the connector is installed in the mounting cavity, and the top surface of the water level sensing capacitor is not higher than the bottom wall of the water receiving cavity; and / or, a first filter is provided at the end of the connecting pipe away from the connector.

[0010] In the preferred embodiment of the water receiving component for the water purification equipment described above, the mesh size of the first filter is 40 to 50 mesh.

[0011] In the preferred embodiment of the water receiving assembly for the water purification equipment described above, the water receiving assembly further includes a water pump, and the water receiving cavity is provided with a water inlet. The water pump is connected to the water inlet so as to extract water from the water receiving cavity; and / or, the water receiving assembly further includes a first filter screen, which is fixedly disposed on the bottom surface of the support plate and covers all the leakage holes; and / or, the support plate is provided with a positioning through hole at its center, which is directly opposite to the water outlet of the water purification equipment; and / or, the inner sidewall of the water receiving cavity is provided with a plurality of spaced support columns, and the support plate is placed on the plurality of support columns with the sidewall of the support plate fitting against the inner sidewall of the water receiving cavity; and / or, the top surface of the support plate is located below the top surface of the water receiving tray, and the distance between the top surface of the support plate and the top surface of the water receiving tray is 2mm to 10mm.

[0012] In the preferred embodiment of the water receiving assembly for the water purification equipment described above, a downwardly recessed drainage cavity is provided on the bottom wall of the water receiving cavity, and the water inlet is provided on the cavity wall of the drainage cavity; and / or, a second filter is provided at the end of the water inlet away from the water pump.

[0013] In the preferred embodiment of the water receiving component for the water purification equipment described above, the first filter screen has a mesh size of 20 mesh; and / or, the second filter sheet has a mesh size of 40 to 50 mesh.

[0014] In the preferred embodiment of the water receiving component for the water purification equipment described above, the water receiving component further includes a second filter component, which includes a connecting cylinder and a second filter screen. The mesh size of the second filter screen is greater than that of the first filter screen. The top of the connecting cylinder is detachably connected to the support plate. The top opening of the connecting cylinder covers all the leakage holes, and the second filter screen is disposed in the bottom outlet of the connecting cylinder.

[0015] In the preferred embodiment of the water receiving component for the water purification equipment described above, the second filter screen has a mesh size of 60.

[0016] In the preferred embodiment of the water receiving component for the water purification equipment described above, the connector and the water receiving tray are made of plastic, and the distance between the top surface of the water level sensing capacitor and the second filter screen is not less than 2cm.

[0017] When the above technical solution is adopted, the water receiving component of the present invention includes a water receiving tray, a support plate and a sensing component. The sensing component includes a water level sensing capacitor installed in the water receiving cavity. This arrangement uses the water level sensing capacitor to detect the water level height in the water receiving cavity. Compared with other water level detection devices, it is small in size, convenient to assemble and use, and can effectively reduce the size of the water purification equipment and reduce the cost of the water purification equipment.

[0018] Furthermore, the sensing component also includes a connector. The water level sensing capacitor is installed on the bottom wall inside the connector. The side wall of the connector surrounds the water level sensing capacitor, thereby stabilizing the detection environment of the water level sensing capacitor. When water droplets fall into the water receiving cavity, the surface of the water in the receiving cavity will fluctuate. Since the water level sensing capacitor is located inside the connector, the outer wall of the connector blocks the fluctuation trend of the water surface, thereby reducing the impact of water surface fluctuation on the water level sensing capacitor. Firstly, it can prevent the fluctuating water from impacting the water level sensing capacitor, thus protecting the water level sensing capacitor. Secondly, it can keep the water level and water surface in the detection area of ​​the water level sensing capacitor stable, avoiding the impact of excessive horizontal fluctuation on the detection results, thereby ensuring the detection accuracy of the water level sensing capacitor. In addition, by setting up the connector, the distance between the water level sensing capacitor and the bottom wall of the water receiving tray can also be increased, thereby increasing the distance between the water level sensing capacitor and the metal parts at the bottom of the water purification equipment, so as to avoid the metal parts affecting the detection of the water level sensing capacitor and ensuring the detection accuracy of the water level sensing capacitor.

[0019] Furthermore, setting the water level sensing capacitor horizontally, compared to setting it vertically or at an angle, can effectively improve its detection accuracy and ensure the accuracy of the detection results.

[0020] Furthermore, a recessed mounting cavity is provided on the bottom wall of the water receiving chamber. The connector is installed in the mounting cavity, and the top surface of the water level sensing capacitor is not higher than the bottom wall of the water receiving chamber. This arrangement allows the water level sensing capacitor to be installed below the bottom wall of the water receiving chamber, thereby enabling more accurate detection of water level changes in the water receiving chamber, improving detection accuracy, and making it more convenient to use.

[0021] Furthermore, a first filter is installed on the connecting pipe to filter impurities and prevent them from entering the connector, thereby ensuring the detection accuracy of the water level sensing capacitor.

[0022] Furthermore, setting the mesh size of the first filter to 40 to 50 mesh not only effectively filters impurities but also allows water to flow smoothly into the connector, effectively improving the detection accuracy of the water level sensing capacitor.

[0023] Furthermore, by setting a water inlet on the water receiving cavity and connecting a water pump to the water inlet, the water pump can draw water out of the water receiving cavity through the water inlet, thereby achieving automatic drainage of the water in the water receiving cavity. By using a water level sensing capacitor in conjunction with the water pump, automatic drainage can be achieved, improving ease of use.

[0024] Furthermore, a first filter screen is installed on the bottom surface of the support plate to filter impurities and prevent them from entering the water receiving cavity, thereby keeping the water receiving cavity clean.

[0025] Furthermore, a positioning through hole is provided at the center of the support plate, which is directly opposite the water outlet of the water purification equipment. Firstly, it can position the water receiving container, making it easy to position it in the place where the water receiving container is placed for water collection; secondly, the support plate can be removed through the positioning through hole for cleaning the water receiving tray.

[0026] Furthermore, by setting multiple spaced support columns on the inner wall of the water receiving cavity to support the bearing plate, and with the side wall of the bearing plate fitting against the inner wall of the water receiving cavity, this arrangement facilitates the disassembly and assembly of the bearing plate, while ensuring that all water on the bearing plate flows into the water receiving cavity through the drainage holes, thereby improving the filtration effect of the first filter screen.

[0027] Furthermore, the distance between the top surface of the support plate and the top surface of the water receiving tray is 2mm to 10mm, so that there is a certain amount of space above the support plate. When there is too much leakage, it can provide enough space to temporarily store the water, so that the water can flow smoothly into the water receiving cavity through the leakage hole without overflowing.

[0028] Furthermore, a downwardly recessed drainage cavity is provided on the bottom wall of the water receiving cavity, and the water inlet is located in the drainage cavity. This arrangement can improve the drainage effect and can drain the water accumulated in the water receiving cavity to the greatest extent possible during drainage.

[0029] Furthermore, a second filter is installed at the end of the water inlet away from the water pump. The second filter filters the discharged water, preventing impurities from entering the water pump and preventing the water pump from becoming clogged or damaged.

[0030] Furthermore, the mesh size of the second filter is set to 40 to 50 mesh, which can maintain a good filtration effect and allow water to be discharged smoothly through the water inlet.

[0031] Furthermore, by setting a second filter component at the bottom of the support plate, and making the mesh size of the second filter screen larger than that of the first filter screen, the leaked water is filtered twice before entering the water receiving chamber, and the second filtration is more precise than the first filtration, thus improving the filtration effect.

[0032] In a second aspect, the present invention provides a drainage control method for a water purification device, the water purification device including the aforementioned water receiving component for the water purification device, the drainage control method comprising: the water level sensing capacitor detecting the capacitance value in the water receiving cavity in real time and recording it as a real-time capacitance value; comparing the real-time capacitance value with a first preset capacitance value; selectively executing a drainage mode based on the comparison result; wherein the drainage mode is to activate the water pump to extract water from the water receiving cavity.

[0033] In the preferred embodiment of the drainage control method for the above-mentioned water purification equipment, the step of "selectively executing the drainage mode according to the comparison result" specifically includes: if the real-time capacitance value is less than the first preset capacitance value, then the drainage mode is not executed; if the real-time capacitance value is not less than the first preset capacitance value, then the drainage mode is executed.

[0034] In a preferred embodiment of the drainage control method for the above-mentioned water purification equipment, during the execution of the drainage mode, the drainage control method further includes: acquiring the capacitance value detected by the water level sensing capacitor in real time and recording it as the actual capacitance value; comparing the actual capacitance value with a second preset capacitance value; and selectively ending the execution of the drainage mode based on the comparison result.

[0035] In the preferred embodiment of the drainage control method for the above-mentioned water purification equipment, the step of "selectively ending the execution of the drainage mode according to the comparison result" specifically includes: if the actual capacitance value is greater than the second preset capacitance value, then the drainage mode continues to be executed; if the actual capacitance value is not greater than the second preset capacitance value, then the execution of the drainage mode ends.

[0036] In the preferred embodiment of the drainage control method for the above-mentioned water purification equipment, during the execution of the drainage mode, the drainage control method further includes: obtaining the cumulative execution time of the executed drainage mode; comparing the cumulative execution time with a preset time; if the cumulative execution time is not less than the preset time, then issuing an alarm; if the cumulative execution time is less than the preset time, then not issuing an alarm.

[0037] When the above technical solution is adopted, the drainage control method of the present invention compares the real-time capacitance value with the first preset capacitance value, and selectively executes the drainage mode according to the comparison result. This setting determines whether the water in the water receiving chamber needs to be discharged based on the comparison result between the real-time capacitance value and the first preset capacitance value, thereby selectively executing the drainage mode, making the water pump work, and automatically drawing out the water in the water receiving chamber, realizing the automatic discharge of water from the water receiving tray. This saves the user from the operation of taking out the water receiving tray to empty the water, effectively improving the user experience, and the judgment is accurate and convenient to control and use.

[0038] Furthermore, during the execution of the drainage mode, the drainage control method also includes: acquiring the capacitance value detected by the water level sensing capacitor in real time and recording it as the actual capacitance value; comparing the actual capacitance value with the second preset capacitance value; selectively ending the execution of the drainage mode based on the comparison result; this setting method controls the cessation of the execution of the drainage mode by comparing the actual capacitance value with the second preset capacitance value, so as to ensure that the water in the water receiving chamber is completely drained.

[0039] Furthermore, during the execution of the drainage mode, the drainage control method also includes: obtaining the cumulative execution time of the executed drainage mode, comparing the cumulative execution time with the preset time, and selectively triggering an alarm based on the comparison result; this setting method allows for the triggering of an alarm if the drainage mode has not ended after an excessively long cumulative execution time, so that users can promptly check the water connection components to see if there is any damage or blockage, effectively improving the user experience.

[0060] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through other components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] As mentioned in the background section, existing water receiving trays increase the size and cost of water purification equipment to some extent, and there are technical problems such as insufficient accuracy in liquid level detection leading to errors.

[0064] The water receiving assembly of the present invention includes a water receiving tray, a support plate, and a sensing component. The sensing component includes a water level sensing capacitor. This arrangement uses the water level sensing capacitor to detect the water level in the water receiving cavity. Compared with other water level detection devices, it is small in size, convenient to assemble and use, and can effectively reduce the size and cost of the water purification equipment.

[0065] Specifically, please also refer to Figures 1 to 4 The water receiving component for a water purification device of the present invention includes a water receiving tray 1, a support plate 2, and a sensing component 3.

[0066] The water receiving tray 1 has a water receiving cavity 11 with a top opening. The water receiving cavity 11 is used to receive and temporarily store water leaking from the outlet of the water purification equipment. The support plate 2 is connected to the water receiving tray 1 and is used to support the water receiving container. The support plate 2 is provided with multiple water leakage holes 21. Water leaking from the outlet enters the water receiving cavity 11 through the water leakage holes 21. The sensing component 3 includes a water level sensing capacitor 32, which is installed on the cavity wall of the water receiving cavity 11. The water level sensing capacitor 32 is used to detect the capacitance value in the water receiving cavity 11, and then the change in capacitance value reflects the height of the water level in the water receiving cavity 11.

[0067] The water receiving component of this invention uses a water level sensing capacitor 32 to detect the water level in the water receiving cavity 11. Specifically, the change in water level in the water receiving cavity 11 is determined by the capacitance value detected by the water level sensing capacitor 32 (wherein, the smaller the capacitance value, the lower the water level, and the larger the capacitance value, the higher the water level). When the capacitance value is higher than the preset capacitance value, an alarm is triggered to remind the user to clean the water receiving tray 1 in time, or the controller directly controls automatic drainage. Compared with other liquid level sensors, the water level sensing capacitor 32 has higher detection accuracy, is smaller in size, and is convenient to install and use, which can effectively reduce the size and cost of the water purification equipment.

[0068] Preferably, the sensing component 3 further includes a connector 31 disposed in the water receiving cavity 11. A connecting pipe 33 is provided on the side wall of the connector 31. The connecting pipe 33 connects the internal space of the connector 31 with the water receiving cavity 11 so that water in the water receiving cavity 11 can enter the interior of the connector 31 through the connecting pipe 33. The water level sensing capacitor 32 is located in the internal space of the connector 31 and is installed on the bottom wall of the connector 31.

[0069] By setting connector 31, the water level sensing capacitor 32 is installed inside connector 31. The side wall of connector 31 surrounds the water level sensing capacitor 32, thereby stabilizing the detection environment of the water level sensing capacitor 32. When water droplets fall into the water receiving cavity 11, the surface of the water in the water receiving cavity 11 will fluctuate. Since the water level sensing capacitor 32 is located inside connector 31, the outer wall of connector 31 blocks the fluctuation trend of the water surface, thereby reducing the impact of water surface fluctuation on the water level sensing capacitor 32. Firstly, it can prevent the fluctuating water from impacting the water level sensing capacitor 32. Secondly, protecting the water level sensing capacitor 32 ensures that the water level and surface in the detection area of ​​the water level sensing capacitor 32 remain stable, preventing excessive fluctuations in the water level from affecting the detection results and thus guaranteeing the detection accuracy of the water level sensing capacitor 32. In addition, installing the water level sensing capacitor 32 inside the connector 31 also increases the distance between the water level sensing capacitor 32 and the bottom wall of the water receiving tray 1, thereby increasing the distance between the water level sensing capacitor 32 and the metal parts at the bottom of the water purification equipment. This prevents the metal parts from affecting the detection of the water level sensing capacitor 32 and ensures the detection accuracy of the water level sensing capacitor 32.

[0070] Preferably, the water level sensing capacitor 32 is horizontally positioned. Horizontally positioning the water level sensing capacitor 32, compared to vertical or inclined positioning, effectively improves its detection accuracy and ensures the accuracy of the detection results.

[0071] Preferably, please continue reading. Figure 1 The bottom wall of the water receiving cavity 11 is provided with a downwardly recessed mounting cavity 12, the connector 31 is installed in the mounting cavity 12, and the top surface of the water level sensing capacitor 32 is not higher than the bottom wall of the water receiving cavity 11.

[0072] By setting the water level sensing capacitor 32 in a position lower than the bottom wall of the water receiving cavity 11, the water level change in the water receiving cavity 11 can be detected more accurately, improving the detection accuracy and making it more convenient to use.

[0073] Preferably, a first filter is provided at the end of the connecting tube 33 away from the connector 31. The first filter is provided on the connecting tube 33 to filter impurities and prevent impurities in the mounting cavity 12 from entering the connector 31, thereby ensuring the detection accuracy of the water level sensing capacitor 32.

[0074] Preferably, the mesh size of the first filter is 40 to 50 mesh. Setting the mesh size of the first filter to 40 to 50 mesh can effectively filter impurities while allowing water to flow smoothly into the connector 31.

[0075] Preferably, please continue reading. Figure 1 and Figure 2The water receiving assembly also includes a water pump 4, and a water inlet 13 is provided on the water receiving cavity 11. The water pump 4 is connected to the water inlet 13 so that water can be pumped out of the water receiving cavity 11.

[0076] By setting a water inlet 13 on the water receiving cavity 11 and connecting a water pump 4 to the water inlet 13, the water pump 4 can draw water out of the water receiving cavity 11 through the water inlet 13, thereby realizing the automatic discharge of water in the water receiving cavity 11. The automatic drainage can be achieved by using the water level sensing capacitor 32 in conjunction with the water pump 4, thus improving the convenience of use.

[0077] Preferably, please also refer to Figures 1 to 5 The water receiving assembly also includes a first filter screen 5, which is fixedly installed on the bottom surface of the support plate 2. The first filter screen 5 covers all the water leakage holes 21 so as to filter the water passing through the water leakage holes 21.

[0078] By setting a first filter screen 5 on the bottom surface of the support plate 2 to filter impurities and prevent impurities from entering the water receiving cavity 11, the water receiving cavity 11 is effectively kept clean.

[0079] Preferably, please also refer to Figure 1 , Figure 2 and Figure 3 The center of the bearing plate 2 is provided with a positioning through hole 22, which is set directly opposite the water outlet of the water purification equipment.

[0080] By setting the positioning through hole 22, firstly, the placement position can be positioned when the water receiving container is placed, making it convenient to receive water; secondly, the support plate 2 can be removed through the positioning through hole 22 for cleaning the water receiving tray 1.

[0081] It should be noted that this invention does not impose any restrictions on the position or installation method of the support plate 2 relative to the water receiving tray 1. In practical applications, those skilled in the art can set the installation position and method of the support plate 2 relative to the water receiving tray 1 according to actual needs. For example, the support plate 2 can be fixedly installed on the top surface of the water receiving tray 1, or the support plate 2 can be detachably installed in the water receiving cavity 11 of the water receiving tray 1, etc. Adjustments and changes to the installation method of the support plate 2 and the water receiving tray, as well as the installation position of the support plate 2 relative to the water receiving tray 1, do not deviate from the basic principles of this invention and should all be limited to the protection scope of this invention.

[0082] In a preferred embodiment, the support plate 2 is detachably installed inside the water receiving cavity 11. Detachable installation of the support plate 2 inside the water receiving cavity 11 facilitates its removal, allowing for cleaning of the water receiving cavity 11 and keeping the water receiving tray 1 clean.

[0083] Preferably, please also refer to Figure 1 and Figure 4 The inner wall of the water receiving cavity 11 is provided with multiple spaced support columns 14, and the bearing plate 2 is placed on the multiple support columns 14, and the side wall of the bearing plate 2 is in contact with the inner wall of the water receiving cavity 11.

[0084] By setting multiple spaced support columns 14 on the inner side wall of the water receiving cavity 11, the support plate 2 can be supported, making it convenient to install and disassemble the support plate 2; the side wall of the support plate 2 is made to fit with the inner side wall of the water receiving cavity 11, ensuring that all the water on the support plate 2 flows into the water receiving cavity 11 through the water leakage hole 21, thereby improving the filtration effect of the first filter screen 5.

[0085] Preferably, the top surface of the support plate 2 is located below the top surface of the water receiving tray 1, and the distance between the top surface of the support plate 2 and the top surface of the water receiving tray 1 is 2-10 mm. This distance provides sufficient space above the support plate 2 to temporarily store water when there is excessive leakage, allowing the water to flow smoothly through the leak hole 21 into the water receiving cavity 11 without overflowing.

[0086] Preferably, please refer to Figure 1 The bottom wall of the water receiving cavity 11 is provided with a downwardly recessed drainage cavity 15, and the water inlet 13 is provided on the cavity wall of the drainage cavity 15.

[0087] A downwardly recessed drainage cavity 15 is provided on the bottom wall of the water receiving cavity 11, and the water inlet 13 is located in the drainage cavity 15. This arrangement can improve the drainage effect and can drain the water accumulated in the water receiving cavity 11 to the greatest extent possible during drainage.

[0088] Preferably, a second filter is provided at the end of the water inlet 13 away from the water pump 4. Providing a second filter at the end of the water inlet 13 away from the water pump 4 can prevent impurities from entering the water pump 4, thus preventing the water pump 4 from becoming clogged or damaged.

[0089] Preferably, the bottom wall of the water receiving cavity 11 is inclined towards the drain cavity 15, and the top surface of the drain cavity 15 is at a lower height than the bottom wall of the water receiving cavity 11. This downward inclination of the bottom wall of the water receiving cavity 11 towards the drain cavity 15 allows water in the water receiving cavity 11 to quickly collect in the drain cavity 15. When using the water pump 4 to drain water, this improves the drainage effect and helps to quickly remove water from the water receiving cavity 11.

[0090] Preferably, the mesh size of the second filter is 40 to 50 mesh. Setting the mesh size of the second filter to 40 to 50 mesh can maintain a good filtration effect while allowing water to smoothly enter and exit the water inlet 13.

[0091] Preferably, please also refer to Figures 4 to 7 The water receiving assembly of the present invention further includes a second filter assembly 6, which includes a connecting cylinder 61 and a second filter screen 62. The mesh size of the second filter screen 62 is greater than that of the first filter screen 5. The top of the connecting cylinder 61 is detachably connected to the support plate 2. The top opening of the connecting cylinder 61 covers all the water leakage holes 21, so that all the water passing through the water leakage holes 21 is concentrated in the connecting cylinder 61, and then can pass through the second filter screen 62 before entering the water receiving cavity 11. The second filter screen 62 is disposed in the bottom outlet of the connecting cylinder 61.

[0092] By setting a second filter assembly 6 at the bottom of the support plate 2, and making the mesh size of the second filter screen 62 greater than that of the first filter screen 5, the leaked water is filtered twice before entering the water receiving cavity 11, thus improving the filtration effect.

[0093] It should be noted that the present invention does not impose any restrictions on the mesh count of the first filter screen 5 and the second filter screen 62. As long as the mesh count of the second filter screen 62 is greater than that of the first filter screen 5, thereby making the filtration accuracy of the second filter screen 62 higher than that of the first filter screen 5, it is acceptable. In practical applications, those skilled in the art can set the mesh count of the first filter screen 5 and the second filter screen 62 according to actual needs. Any adjustments and changes to the mesh count of the first filter screen 5 and the second filter screen 62 do not deviate from the basic principles of the present invention and should be limited to the protection scope of the present invention.

[0094] In one embodiment, the first filter screen 5 has a mesh size of 20, and the second filter screen 62 has a mesh size of 60.

[0095] Specifically, please also refer to Figures 6 to 8 The bottom surface of the bearing plate 2 is provided with two opposing connecting plates 23. The connecting plates 23 are provided with limiting grooves 231, which extend along the length of the connecting plates 23. The connecting cylinder 61 is provided with a limiting plate 611 on the side near the connecting plates 23. The two limiting plates 611 are respectively located in the two limiting grooves 231. One end of the limiting groove 231 has an opening in the length direction so that the limiting plate 611 can be assembled into the limiting groove 231 through the opening. The other end of the limiting groove 231 has a positioning plate 232. When the limiting plate 611 is located in the limiting groove 231, the end of the limiting plate 611 abuts against the positioning plate 232 so as to quickly assemble the bearing plate 2 and the connecting cylinder 61 into place.

[0096] The above setup is simple in structure and allows for quick assembly of the carrier plate 2 and the second filter component 6.

[0097] Preferably, the connector 31 and the water tray 1 are made of plastic, and the distance between the top surface of the water level sensing capacitor 32 and the second filter screen 62 is not less than 2 cm.

[0098] The connector 31 and the water tray 1 are made of plastic to avoid the metal components affecting the detection of the water level sensing capacitor 32. The distance between the top surface of the water level sensing capacitor 32 and the second filter screen 62 is not less than 2cm, so that the metal filter screen is outside the sensing distance of the water level sensing capacitor 32. This avoids the metal filter screen from having a negative impact on the detection of the water level sensing capacitor 32, so as to ensure the detection accuracy of the water level sensing capacitor 32.

[0099] In addition, the water purification device of the present invention also includes a controller, which is communicatively connected to the water level sensing capacitor 32 and the water pump 4, and the controller is configured to execute the drainage control method of the water purification device of the present invention.

[0100] Based on the aforementioned water receiving component for water purification equipment, this invention also provides a drainage control method for water purification equipment. The method determines whether water needs to be drained from the water receiving chamber based on a comparison between a real-time capacitance value and a first preset capacitance value, thereby selectively executing a drainage mode to activate a water pump and automatically extract water from the water receiving chamber. This automatically drains water from the water receiving tray, avoiding the need for the user to remove the tray and empty the water, effectively improving the user experience. Furthermore, the method provides accurate judgment and convenient control.

[0101] Specifically, please refer to Figure 9 The drainage control method of the water purification equipment of the present invention specifically includes the following steps:

[0102] S100: The water level sensing capacitor detects the capacitance value inside the water inlet cavity in real time and records it as the real-time capacitance value.

[0103] Specifically, the water level sensing capacitor contains an element that can detect the capacitance value. As the water level changes, the detected capacitance value will also change accordingly. When there is no water, the capacitance value will decrease, while when there is water, the capacitance value will increase.

[0104] The water level sensing capacitor detects the capacitance value inside the water receiving chamber in real time and records it as the real-time capacitance value, so as to determine whether the water in the water receiving chamber needs to be cleaned based on the real-time capacitance value.

[0105] S200: Compare the real-time capacitance value with the first preset capacitance value.

[0106] It should be noted that the present invention does not impose any restrictions on the specific value of the first preset capacitance value. In practical applications, those skilled in the art can limit the specific value of the first preset capacitance value according to actual needs.

[0107] In practical applications, before the water purification equipment leaves the factory, technicians conduct experiments on the water receiving chamber at different water levels to detect the capacitance values ​​corresponding to different water levels, and create a "Water Level Height and Capacitance Value Comparison Table". Based on the depth and cross-sectional area of ​​the water receiving tray, the capacitance value corresponding to a water level between 2 / 3 and 3 / 4 of its depth is selected as the first preset capacitance value. This first preset capacitance value can be a default setting (a value set before leaving the factory) or a parameter automatically set by the user. Specifically, users can set it themselves via an app or control panel according to the "Water Level Height and Capacitance Value Comparison Table" provided in the instruction manual.

[0108] S300: Based on the comparison results, selectively execute the drainage mode.

[0109] The real-time capacitance value is compared with the first preset capacitance value to determine whether the real-time capacitance value is less than the first preset capacitance value, so as to selectively execute the drainage mode according to the comparison result.

[0110] The drainage mode involves activating a water pump to extract water from the water inlet chamber.

[0111] The drainage control method of the present invention determines whether the water in the water receiving chamber needs to be drained based on the comparison result between the real-time capacitance value and the first preset capacitance value, thereby selectively executing the drainage mode to automatically drain the water in the water receiving tray, saving the user the operation of taking out the water receiving tray to empty the water, effectively improving the user experience, and the judgment is accurate and convenient to control and use.

[0112] In one implementation, please refer to Figure 10 Step S300, “Selectively execute drainage mode according to comparison results”, specifically includes the following steps: if the real-time capacitance value is less than the first preset capacitance value, then execute step S310; if the real-time capacitance value is not less than the first preset capacitance value, then execute step S320.

[0113] S310: Do not execute drainage mode.

[0114] If the real-time capacitance value is less than the first preset capacitance value, it means that the water level in the water receiving chamber has not yet reached the water level required for drainage. The water receiving tray can continue to receive water and will not overflow. In this case, the drainage mode is not executed.

[0115] S320: Execute drainage mode.

[0116] If the real-time capacitance value is not less than the first preset capacitance value, it indicates that the water level in the water receiving chamber has reached the water level required for drainage. If the use continues, there is a risk of overflow. Therefore, the drainage mode is executed, and the water pump is run to extract the water from the water receiving chamber.

[0117] In one implementation, please refer to Figure 11 During the execution of the drainage mode, the drainage control method of the present invention further includes the following steps:

[0118] S410: Real-time acquisition of the capacitance value detected by the water level sensing capacitor, recorded as the actual capacitance value.

[0119] During the drainage process, the capacitance value detected by the water level sensing capacitor is obtained in real time and recorded as the actual capacitance value. This value is then used to determine the extent of water discharge from the water inlet chamber and whether to stop the drainage mode.

[0120] S420: Compare the actual capacitance value with the second preset capacitance value.

[0121] It should be noted that the present invention does not impose any restrictions on the specific value of the second preset capacitance value. In practical applications, those skilled in the art can limit the specific value of the second preset capacitance value according to actual needs.

[0122] In practical applications, before the water purification equipment leaves the factory, technicians conduct experiments by measuring different water levels in the receiving chamber to determine the capacitance values ​​corresponding to each water level. This results in a "Water Level and Capacitance Value Comparison Table." Based on the depth and cross-sectional area of ​​the receiving tray, a second preset capacitance value is selected corresponding to a water level between 0 and 1 / 3 of its depth. This second preset capacitance value can be a default setting (value set before leaving the factory) or a user-defined parameter. Specifically, users can set this value themselves via an app or control panel using the "Water Level and Capacitance Value Comparison Table" provided in the instruction manual.

[0123] S430: Based on the comparison results, selectively terminate the execution of the drainage mode.

[0124] The actual capacitance value is compared with the second preset capacitance value to determine whether the actual capacitance value is greater than the second preset capacitance value, so that the drainage mode can be selectively terminated based on the comparison result.

[0125] For details, please continue reading Figure 11 Step S430, “Selectively end the execution of drainage mode according to the comparison result”, specifically includes: if the actual capacitance value is greater than the second preset capacitance value, then execute step S431; if the actual capacitance value is not greater than the second preset capacitance value, then execute step S432.

[0126] S431: Continue to execute drainage mode.

[0127] If the actual capacitance value is greater than the second preset capacitance value, it means that there is still a lot of water remaining in the water inlet chamber, and the drainage mode needs to be continued.

[0128] S432: End execution of drainage mode.

[0129] If the actual capacitance value is not greater than the second preset capacitance value, it means that the water remaining in the water inlet chamber is not higher than the preset water level, and the drainage mode can be terminated.

[0130] This implementation controls the cessation of the drainage mode by comparing the actual capacitance value with the second preset capacitance value, so as to ensure that the water in the water receiving chamber is drained as cleanly as possible.

[0131] In one implementation, please refer to Figure 12 During the execution of the drainage mode, the drainage control method of the present invention further includes the following steps:

[0132] S510: Get the cumulative execution time of the executed drainage mode.

[0133] Specifically, the cumulative execution time of the current drainage mode can be obtained by subtracting the current time from the time when the drainage mode was started.

[0134] S520: Compare the cumulative execution time with the preset time.

[0135] It should be noted that this invention does not impose any limitations on the preset time. In practical applications, those skilled in the art can set the preset time according to actual needs. For example, the preset time can be 30 seconds, or 1 minute, etc. Adjustments and changes to the preset time do not deviate from the basic principles of this invention and should be limited to the scope of protection of this invention.

[0136] S530: Based on the comparison results, selectively trigger alarms.

[0137] The cumulative execution time is compared with the preset time to determine whether the cumulative time is less than the preset time, so that alarms can be selectively triggered based on the comparison results.

[0138] For details, please continue reading Figure 12 Step S530, "selectively triggering an alarm based on the comparison results," specifically includes: if the cumulative execution time is not less than the preset time, then step S531 is executed; if the cumulative execution time is less than the preset time, then step S532 is executed.

[0139] S531: Issue an alarm.

[0140] If the cumulative execution time is not less than the preset time, it means that the drainage mode has been running for a long enough time to drain the water from the water inlet chamber. However, if the drainage operation has not ended, it means that a device has malfunctioned, and an alarm will be triggered to remind the user to check it in time.

[0141] S532: No alarm will be triggered.

[0142] If the cumulative execution time is less than the preset time, it means that the water in the water inlet chamber may not have been completely drained, and no alarm will be triggered.

[0143] In this embodiment, the cumulative execution time of the drainage mode is obtained, the cumulative execution time is compared with a preset time, and an alarm is selectively triggered based on the comparison result. In order to remind the user to check the water connection components in time if the drainage mode is not terminated after a long period of cumulative execution, so as to effectively improve the user experience.

[0144] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
