[0052] The present invention proposes a water supply device 1, please combine Figure 1 , Figure 2 and Figure 3 As shown, the water supply equipment 1 includes a box body 10, a filter assembly 30 and a first water tank 20 arranged in the box body 10, and a water storage cup 41 arranged outside the box body 10. The water storage cup 41 is placed above the water receiving box 70. The first water tank 20 is respectively connected to the filter assembly 30 and the water storage cup 41. The first water tank 20 is used to store pure water filtered by the filter assembly 30 and supply pure water to the water storage cup 41.

[0053] The water supply device proposed in the present invention can use the first water tank 20 to store pure water filtered by the filter assembly 30, and use the first water tank 20 to supply water to multiple water storage cups 41 arranged outside the box body 10. Even if the user takes away the water storage cups 41, the water supply device 1 can still use the first water tank 20 to supply pure water to external water-using devices, which will not affect the continued use of the water supply device 1.

[0054] The water supply device 1 also includes a second water tank 12, which is used to connect to a water source or store raw water. The second water tank 12 supplies raw water to the filter assembly 30. The filter assembly 30 includes a pre-filter element (not shown in the figure), a reverse osmosis filter element (not shown in the figure) and a post-filter element (not shown in the figure). The type of the pre-filter element can be PP in different forms, activated carbon in different forms, ultrafiltration, and nanofiltration. The raw water in the second water tank 12 first enters the pre-filter element, and then enters the reverse osmosis filter element after being roughly filtered by the pre-filter element. After being filtered by the reverse osmosis filter element, it is divided into one path of pure water and one path of waste water. The waste water flows into the waste water channel from the reverse osmosis waste water outlet, and finally the waste water flows back into the second water tank 12; the pure water flows into the post-filter element and flows into the first water tank 20 after being filtered by the post-filter element for drinking.

[0055] Among them, the type of post-filter element can be activated carbon in different forms, and the post-filter element and the pre-filter element can be two independent filter elements or a composite filter element. The composite filter element has the filtering function of the pre-filter element and the post-filter element. There are two non-interfering flow paths inside the composite filter element. One flow path is used for coarse filtration, which is equivalent to the pre-filter element. The raw water enters the reverse osmosis filter element after coarse filtration in this flow path. The other flow path is used for re-filtration, which is equivalent to the post-filter element. The pure water filtered by the reverse osmosis filter element is filtered again from this flow path and finally flows out from the water outlet of the composite filter element.

[0056] In detail, the pure water filtered by the filter assembly 30 is output to the first water tank 20 for storage, and the first water tank 20 is also used to supply pure water to the water storage cup 41, which is arranged outside the box body 10, so that the user can take the water in the water storage cup 41 at any time to meet the user's large-scale pure water use needs. When the user has a large amount of pure water and takes away the water storage cup 41, the water supply device 1 can still use the first water tank 20 to store water and supply pure water to the external water-using device, which does not affect the continued use of the water supply device 1.

[0057] The first water tank 20 may supply water to the water storage cup 41 by actively pumping water, for example, by arranging a water pump on the pipeline connecting the first water tank 20 and the water storage cup 41, and using the water pump to pump the water in the first water tank 20 to the water storage cup 41. Alternatively, the first water tank 20 may supply water to the water storage cup 41 by passive delivery, for example, the pipeline connecting the first water tank 20 and the water storage cup 41 is arranged near the bottom of the first water tank 20 and the water storage cup 41, so that the first water tank 20, the water storage cup 41 and the pipeline connecting the first water tank 20 and the water storage cup 41 together form a communicating vessel structure, so that the pure water in the first water tank 20 automatically flows into the water storage cup 41.

[0058] In some embodiments of the present invention, please combine Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first water tank 20 is provided with a first water outlet 212, and the water storage cup 41 is provided with a first plug interface 412. The first water tank 20 is used to store pure water filtered by the filter assembly 30. The water supply device 1 also includes a water supply connector 23, which is installed on the first water tank 20 and communicates with the first water outlet 212. The water supply connector 23 is detachably plugged into the first plug interface 412 and connects the first water tank 20 and the water storage cup 41. By using the plug-in connection method between the water supply connector 23 and the first plug interface 412, the user only needs to align the water supply connector 23 with the first plug interface 412 and then gently push it in to complete the plug-in operation, which is convenient for the water storage cup 41 to be used. Among them, the first water outlet 212 is arranged near the bottom of the water tank, and the first plug interface 412 is arranged near the bottom of the water storage cup 41, so that the first water tank 20, the water supply connector 23 and the water storage cup 41 together constitute a communicating vessel structure. According to the communicating vessel principle, when the same liquid does not flow, the liquid levels in each container are level. Therefore, when the water level in the first water tank 20 is higher than the water level in the water storage cup 41, under the action of gravity, the pure water in the first water tank 20 will automatically flow to the water storage cup 41 until the water levels of the two are equal. Conversely, when the water level in the water storage cup 41 is higher than the water level in the first water tank 20, the pure water in the water storage cup 41 will also automatically flow to the first water tank 20 to maintain the water level balance. The communicating vessel structure enables the pure water in the first water tank 20 to flow automatically into the water storage cup 41 without the need for additional power equipment, saving energy, and the user can realize the automatic water storage of the water storage cup 41 without manual operation, thereby improving the convenience of use. In addition, the communicating vessel structure can ensure that the water levels in the first water tank 20 and the water storage cup 41 are always maintained at a similar height, making it convenient for the user to observe and grasp the water volume. The design of the communicating vessel structure is simple and reliable, does not require complex control devices and piping systems, and reduces the cost and failure rate of the equipment.

[0059] For details, please combine Figure 3 , Figure 4 and Figure 5As shown, the water supply connector 23 includes a main body 231, a first plug-in portion 232 and a second plug-in portion 233 connected to each other. The first plug-in portion 232 extends along the first direction and is plugged and connected with the first plug-in port 412. The second plug-in portion 233 is plugged into the first water outlet 212. The first plug-in portion 232 is set as a cylindrical plug, and its outer surface is smooth to ensure the smoothness of the insertion and removal process. The first plug-in port 412 of the water storage cup 41 is set as a cylindrical jack with an inner diameter slightly larger than the outer diameter of the water supply connector 23. The sizes of the two are precisely matched, so that the plug-in is tight and stable. A rubber sealing ring is set in the first plug-in port 412 as a sealing member. Rubber has good elasticity and sealing properties, and can adapt to different temperature and pressure changes. When the water supply connector 23 is inserted into the first plug-in port 412, the rubber sealing ring is arranged outside the water supply connector 23, and the rubber sealing ring is squeezed and deformed, filling the gap between the water supply connector 23 and the first plug-in port 412 to form a seal.

[0060] In this embodiment, the first direction is parallel to the horizontal plane, that is, the plugging direction of the water storage cup 41 and the water supply connector 23 is the horizontal direction. When the user places the water storage cup 41, the water storage cup 41 can be placed on the water receiving box 70 first, and then the water storage cup 41 can be moved horizontally to plug the first plugging portion 232 into the first plug port 412, which makes the placement process of the water storage cup 41 more labor-saving. In some embodiments, due to the manufacturing and assembly errors of parts, when the water supply device 1 is placed on a horizontal plane, the extension direction of the first plugging portion 232 (that is, the first direction) can also be at a smaller angle with the horizontal plane.

[0061] In some embodiments of the present invention, please combine Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the first water tank 20 includes a first shell 21 and a water supply installation portion 210 arranged on the first shell 21. The interior of the first shell 21 defines a first water storage chamber 201 for storing pure water. The water supply installation portion 210 includes a first tube body portion 215 communicating with the first water storage chamber 201 and a second tube body portion 216 communicating with the first tube body portion 215. The first tube body portion 215 and the second tube body portion 216 are both tubular. The interiors of the first tube body portion 215 and the second tube body portion 216 are hollow and form a channel for pure water to flow. The outer contours of the first tube body portion 215 and the second tube body portion 216 and the contours of their inner cavities can be set to cylindrical, prismatic or irregular shapes, etc. The first tube body portion 215 and the second tube body portion 216 are arranged perpendicular to each other, the first tube body portion 215 extends along the first direction, the second tube body portion 216 extends along the second direction (i.e., the vertical direction), the top of the second tube body portion 216 defines the first water outlet 212, and the second plug-in portion 233 is arranged as a circular tubular structure extending along the second direction. The second plug-in portion 233 is plugged into the second tube body portion 216 from top to bottom, so that the water supply connector 23 is connected to the first water outlet 212.

[0062] It should be noted that the water supply connector 23 and the first water tank 20 are arranged in a plug-in connection mode. After the first water tank 20 is fixedly installed to the box body 10, the relative position of the first plug-in portion 232 in the vertical direction with the first water tank 20 and the water storage cup 41 is adjusted by adjusting the axial position of the second plug-in portion 233 in the second tube body portion 216, so that the first plug-in portion 232 can be aligned with the first plug port 412 of the water storage cup 41, thereby overcoming the problem that the first plug-in portion 232 cannot be aligned with the first plug port 412 due to factors such as assembly errors.

[0063] In some embodiments of the present invention, please combine Figure 3 , Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, the water supply device 1 further includes a first sealing member 2161, which includes a tubular sealing inner sleeve 21611, a sealing outer sleeve 21612 sleeved outside the sealing inner sleeve 21611, and a sealing connection portion 21613 connecting the sealing inner sleeve 21611 and the sealing outer sleeve 21612. The outer diameter of the sealing inner sleeve 21611 matches the inner diameter of the second tube body 216, and can be tightly inserted into the second tube body 216. The sealing inner sleeve 21611 is made of a material with certain elasticity and flexibility, such as rubber, silicone, etc., to ensure a good seal with the second tube body 216. The sealing outer sleeve 21612 is sleeved outside the second tube body 216. The inner diameter of the sealing outer sleeve 21612 is greater than the outer diameter of the second tube body 216. There is a gap space between the sealing inner sleeve 21611 and the sealing outer sleeve 21612 to accommodate the second tube body 216. The sealing outer sleeve 21612 and the sealing inner sleeve 21611 are made of the same or different materials. When the sealing outer sleeve 21612 and the sealing inner sleeve 21611 are made of different materials, the sealing outer sleeve 21612 can be made of a relatively hard material, such as plastic, metal, etc., to protect and fix the sealing inner sleeve 21611. The sealing connection part 21613 connects the sealing inner sleeve 21611 and the sealing outer sleeve 21612 to ensure that the connection between the two is firm and reliable. The sealing connection part 21613 can be an annular structure or a plurality of connection points. The specific form depends on the design and use requirements of the seal.

[0064] Please combine Figure 3 , Figure 5 and Fig.13 As shown, the sealing inner sleeve 21611 is inserted into the second tube body 216. Since the sealing inner sleeve 21611 is elastic, it will be slightly deformed during the insertion process and fit tightly on the inner wall of the second tube body 216 to form a first seal. The second plug-in part 233 is inserted into the sealing inner sleeve 21611. The outer diameter of the second plug-in part 233 matches the inner diameter of the sealing inner sleeve 21611 and can be tightly inserted therein. After the second plug-in part 233 is inserted into the sealing inner sleeve 21611, the sealing inner sleeve 21611 will be further deformed to form a second seal with the second plug-in part 233. The first water outlet 212 is sealed by the cooperation between the sealing inner sleeve 21611 and the inner wall of the second tube body 216 and the outer peripheral surface of the second plug-in part 233, thereby preventing the first water tank 20 from leaking at the first water outlet 212.

[0065] Furthermore, please combine Figure 3 , Figure 5 and Fig.13As shown, the inner wall of the sealing inner sleeve 21611 is provided with at least one annular protrusion 216111 extending along the circumference of the sealing inner sleeve 21611. The annular protrusion 216111 can increase the sealing contact area and improve the sealing pressure, thereby effectively preventing pure water leakage.

[0066] Furthermore, please combine Figure 3 , Figure 5 and Fig.13 As shown, the inner wall of the sealing inner sleeve 21611 facing the end of the water supply joint 23 is provided with a first guide structure 218 with a gradually expanding inner diameter. Specifically, the first guide structure 218 is a conical inner diameter gradually expanding shape. Starting from the end of the sealing inner sleeve 21611, the inner diameter gradually decreases to be equal to the inner diameter of the sealing inner sleeve 21611, forming a smooth transition slope. The inclination angle of the transition slope relative to the axis of the sealing inner sleeve 21611 can be adjusted according to actual needs, and the inclination angle can be any value between 15° and 45°, for example: 15°, 20°, 30°, 40°, 45°, etc.

[0067] By providing the first guide structure 218, when the second plug-in portion 233 is inserted into the sealing inner sleeve 21611, the gradually expanding inner diameter design of the first guide structure 218 can provide guidance for the water supply connector 23. The end of the water supply connector 23 first contacts the wider part of the first guide structure 218, and then during the insertion process, as the inner diameter gradually decreases, it can easily slide into the inside of the sealing inner sleeve 21611. This design greatly reduces the difficulty of insertion and improves the convenience of operation. In addition, the first guide structure 218 can guide the water supply connector 23 to be inserted at the correct angle, extending the service life of the sealing inner sleeve 21611 and the water supply connector 23. Due to the gradually expanding inner diameter of the first guide structure 218, the deformation of the sealing inner sleeve 21611 is more uniform during the insertion of the second plug-in portion 233 into the sealing inner sleeve 21611, which helps to improve the stability of the seal.

[0068] In other embodiments, the first guide structure 218 can also be designed to have an arc-shaped transition with a gradually expanding inner diameter. For example, a circular arc curve or a parabolic curve can be used to achieve a gradual increase in the inner diameter. This design can make the water supply connector 23 smoother during insertion and reduce jamming and resistance.

[0069] In some embodiments of the present invention, Figure 6 and Fig. 9As shown, the first water tank 20 further includes a first water inlet 211 and a first air outlet 213. The first water inlet 211 is connected to the filter assembly 30. The pure water filtered by the filter assembly 30 flows into the first water tank 20 through the first water inlet 211. The first water inlet 211 is arranged at the bottom of the first water tank 20. The first water inlet 211 and the first water outlet 212 are respectively located on opposite sides of the first water tank 20, so that the first water tank 20 forms a bottom water inlet and bottom water outlet structure, so that the water can form a relatively smooth flow path in the first water tank 20. The newly entered water flows in from the first water inlet 211 at the bottom, pushing the original water in the first water tank 20 to flow toward the water outlet, so as to minimize the generation of dead water areas, so that the water in the water tank can be fully circulated and renewed, thereby realizing the continuous circulation of water, which helps to maintain the freshness of the water and prevent the water from being stationary for a long time in the first water tank 20 to produce odor or breed bacteria.

[0070] like Figure 6 As shown, the first exhaust port 213 is arranged at the top of the first water tank 20. When pure water enters the first water tank 20 from the first water inlet 211, the original air in the first water tank 20 will be squeezed toward the top. If there is no exhaust port, the air will form air resistance in the water tank, hindering the normal flow of water. The first exhaust port 213 arranged at the top can timely exhaust the air in the water tank, ensuring that water can smoothly flow in from the first water inlet 211 and flow out from the first water outlet 212, thereby ensuring the normal operation of the first water tank 20.

[0071] Furthermore, during the process of filling and draining the first water tank 20, the pressure in the first water tank 20 will change. The first exhaust port 213 can allow the first water tank 20 to communicate with the outside atmosphere, thereby maintaining the pressure in the first water tank 20 balanced with the outside atmospheric pressure. This helps prevent the first water tank 20 from being deformed, broken, or damaging the connecting pipes and equipment due to excessive pressure difference.

[0072] It should also be noted that if the air in the first water tank 20 cannot be discharged in time, it may provide conditions for the growth of microorganisms. Microorganisms are easy to reproduce in a humid, warm and airy environment, thereby contaminating the water in the water tank. The first exhaust port 213 can discharge the air in the first water tank 20, reduce the possibility of microorganism growth, and ensure the hygienic safety of pure water.

[0073] In some embodiments of the present invention, Figure 7 and Fig. 9As shown, the inner wall of the first water tank 20 is provided with a plurality of first reinforcing ribs 214, the length direction of the first reinforcing ribs 214 extends in the vertical direction, and the plurality of first reinforcing ribs 214 are distributed on the inner wall of the first water tank 20, which can effectively increase the rigidity and strength of the first water tank 20. When the first water tank 20 is filled with water or subjected to external pressure, the first reinforcing ribs 214 can share part of the pressure to prevent the first water tank 20 from being deformed or broken. In particular, in the height direction of the first water tank 20, the presence of the first reinforcing ribs 214 can resist the longitudinal stress generated by the gravity and pressure of the water, and improve the overall stability of the first water tank 20.

[0074] Furthermore, the height of the first reinforcing rib 214 protruding from the inner wall of the first water tank 20 increases from top to bottom, and such a setting can play a certain guiding role in the water flow in the first water tank 20. When pure water enters the water tank, the first reinforcing rib 214 at a higher position has less obstruction to the water flow, and the water can flow more smoothly; and as the water level drops, the higher reinforcing ribs at a lower position will gradually play a certain guiding role in the water flow, so that the water flows out more evenly from the first water outlet 212. In this way, it can prevent the water flow from forming a vortex or local stagnation in the first water tank 20, improve the fluidity and renewal speed of the water, and help reduce the accumulation of impurities and sediments in the water at the bottom of the water tank.

[0075] In some embodiments of the present invention, please combine Figure 6 , Figure 7 and Figure 8 As shown, the water supply device 1 also includes a liquid level detection component 22, which is arranged in the first water tank 20 and is used to detect the water level data in the first water tank 20. When the liquid level detection component 22 detects that the water level data in the first water tank 20 is lower than the first water level, it means that the water in the first water tank 20 is insufficient, and the water supply device 1 needs to start making water to replenish the water to ensure that there is sufficient pure water supply at any time. When the water level data is higher than the second water level, it means that the water in the water tank is sufficient, and the water supply device 1 stops making water to avoid the overflow of pure water caused by excessive water storage in the first water tank 20.

[0076] The first water level is a warning water level, which means that the amount of water in the first water tank 20 is close to the minimum acceptable level. The setting of this water level needs to take into account the actual use needs and the water production capacity of the water supply equipment 1. In this embodiment, the total water storage height dimension of the first water tank 20 is H, the height dimension of the first water level is h1, and the value range of h1 / H is 0.15-0.20. For example, h1 / H can be 0.15, 0.16, 0.17, 0.18, 0.18, 0.20, etc., so that the setting height of the first water level is more appropriate, that is, it can start water production when the amount of pure water in the first water tank 20 is small, reduce the number of times the equipment runs and the energy consumption, and when the water level in the first water tank 20 is reduced to the first water level, there is still about one-fifth of pure water stored in the first water tank 20, and pure water can still be supplied to the user, avoiding the situation of untimely water supply, thereby improving the user's experience.

[0077] The height dimension of the second water level is h2, and the value range of h2 / H is 0.75-0.90. For example, h1 / H can be 0.75, 0.80, 0.85, 0.90, etc., that is, the second water level is higher than the first water level, and the second water level is a safe water level upper limit. When the water level in the first water tank 20 reaches the second water level, the water supply device 1 stops making water to prevent the water tank from overflowing or causing damage to the device.

[0078] The liquid level detection component 22 includes but is not limited to a pressure sensor, an ultrasonic detection device, a capacitive liquid level gauge, etc. For example, in some embodiments, a pressure sensor is installed at the bottom of the first water tank 20 to indirectly determine the water level by detecting the pressure of water on the bottom of the water tank. The pressure of water is proportional to the water level, and the water level data can be accurately calculated by measuring the pressure value. This detection method is applicable to water tanks of various shapes and sizes, and has high accuracy and stability. In other embodiments, the liquid level detection component 22 is a capacitive liquid level gauge, which includes two electrodes, which are respectively installed at the first water level and the second water level position in the water tank. When the water level changes, the dielectric constant of water will change the capacitance value between the electrodes. The water level can be determined by measuring the change in capacitance value.

[0079] In this embodiment, the liquid level detection assembly 22 includes a float, a sensor and a slide bar 227. The float is usually made of a material with a density less than that of water, such as plastic, foam, etc. The shape of the float can be spherical, cylindrical or other shapes suitable for floating in water. The float slides up and down on the slide bar 227 as the water level in the first water tank 20 changes, and the height of the water level in the water tank is reflected by the change in the position of the float.

[0080] The slide bar 227 is installed in the first water tank 20 and arranged in the vertical direction. The slide bar 227 is made of a solid material, such as stainless steel, aluminum alloy, etc., to ensure stability in the water tank. The slide bar 227 provides guidance and support for the float, so that the float can accurately slide up and down along the slide bar 227 under the action of buoyancy.

[0081] The sensor is fixed on the slide bar 227. The sensor includes but is not limited to a photoelectric sensor, a Hall sensor and a capacitive sensor. The sensor is used to detect the position of the float and convert it into corresponding water level data. The sensor has the characteristics of high precision, high reliability and fast response to accurately reflect the change of the water level in the first water tank 20.

[0082] In an exemplary embodiment, please combine Figure 6 , Figure 7 and Figure 8 As shown, the sensor adopts a Hall sensor.

The first float 221 floats up and down with the water level in the first water tank 20. When the water level reaches or exceeds the first water level, the first float 221 floats up and contacts the second baffle 224. The first Hall element senses the first magnet and generates electrical signal data to determine that the current water level reaches the first water level. When the water level reaches or falls below the first water level, the first float 221 moves downward and separates from the second baffle 224. The distance between the first magnet and the first Hall element is too large, exceeding the sensing distance of the first Hall element, and generates electrical signal data indicating that the current water level is lower than the first water level.

[0083] The height of the fourth baffle 226 in the first water tank 20 is equal to the second water level, the second Hall element is installed on the fourth baffle 226, the second float 222 is arranged between the third baffle 225 and the fourth baffle 226, and the second float 222 is provided with a second magnet (not shown in the figure) cooperating with the second Hall element, the second float 222 floats up and down with the water level in the first water tank 20, when the water level reaches or exceeds the second water level, the second float 222 floats up and contacts the fourth baffle 226, the second Hall element senses the second magnet and generates electrical signal data to determine that the current water level reaches the second water level, when the water level reaches or falls below the second water level, the second float 222 moves downward and separates from the fourth baffle 226, the distance between the second magnet and the second Hall element is too large, exceeding the sensing distance of the second Hall element, and the second Hall element generates electrical signal data indicating that the current water level is lower than the second water level.

The other limiting nut is located outside the first water tank 20 and can abut against the outer wall surface of the top cover 25. The two limiting nuts limit the movement of the slide bar 227 relative to the top cover 25 along the axial direction of the slide bar 227.
