[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 3 and Figure 8 As shown, a refrigeration module includes a body 11, the body 11 is provided with a drain port 2 and an inspection box 4 for accommodating the drain port 2, the inspection box 4 includes a box body 41 for accommodating the drain port 2, a cover body 5 for covering or opening the box body 41, and a sensing mechanism 6 for sensing whether the cover body 5 is covered in place on the box body 41.

[0031] Specifically, in some embodiments, the body 11 is used in the refrigeration module to refrigerate the filtered pure water to provide users with low-temperature drinking water with a relatively low temperature. The refrigeration module is provided with a drainage system for discharging condensed water or idle waste water generated during the internal refrigeration process. The bottom of the refrigeration module is provided with a drainage port 2 for connecting the drainage system to the outside world. The sensing mechanism 6 is an electronic switch element, which is used to detect whether the box body 41 is opened or closed and is electrically connected to the body 11, so that the sensing mechanism 6 controls the opening and closing of the drainage system.

[0032] More specifically, when the box body 41 is closed, the sensing mechanism 6 forms an energized closed-circuit state. The drainage system is stopped in the closed-circuit state of the sensing mechanism 6 to avoid drainage blockage and water leakage caused by running the drainage system before the inspection box 4 is opened. After the cover body 5 is opened, the sensing mechanism 6 is in an open-circuit state without power, and the user can operate the refrigeration module to drain water. The drainage system can operate normally in the open-circuit state of the sensing mechanism 6. After the condensed water or idle waste water generated during the refrigeration process is discharged from the drain port 2, the user re-closes the cover body 5, and the sensing mechanism 6 re-forms an energized closed-circuit state to stop the drainage system.

[0033] like Figure 3 and Figure 8 As shown, the induction mechanism 6 includes a first magnetic induction component 61 and a second magnetic induction component 62 for magnetically cooperating with the first magnetic induction component 61, one of the first magnetic induction component 61 and the second magnetic induction component 62 is installed on the cover 5, and the other is installed on the box body 41. The first magnetic induction component 61 is a reed switch, and the second magnetic induction component 62 is a magnet.

[0034] Specifically, in some embodiments, the sensing mechanism 6 includes a sensing component composed of a first magnetic sensing component 61 and a second magnetic sensing component 62 for detecting whether the cover body 5 is properly covered on the box body 41. Optionally, the first magnetic sensing component 61 can be a magnet or a reed switch, and the second magnetic sensing component 62 can be a reed switch or a magnet used in conjunction with the first magnetic sensing component 61. The reed switch controls the on and off of the internal reed through the magnetic effect of the magnet, and uses the magnet to approach or move away to achieve connection or disconnection. Preferably, the first magnetic sensing component 61 is a reed switch, and the second magnetic sensing component 62 is a reed switch. 62 is a magnet, and the reed switch is arranged on the cover body 5 as a movable opening and closing side, and the magnet is arranged on the box body 41 as a fixed side. When the reed switch is close to the magnet, it can be in a closed state. When the reed switch is in the closed state, the refrigeration module can operate the refrigeration system normally but stop the drainage system to avoid continued drainage when the cover body 5 is closed. When the reed switch is far away from the magnet, it can be in an open circuit state. When the reed switch is in the open circuit state, the refrigeration module stops operating the refrigeration system but can operate the drainage system normally to avoid hidden dangers caused by the refrigeration system continuing to refrigerate when the cover body 5 is opened.

[0035] Specifically, in some embodiments, the first magnetic induction component 61 can also be arranged on the box body 41, and the second magnetic induction component 62 is arranged on the cover body 5. Optionally, the first magnetic induction component 61 can be a magnet or a reed switch, and the second magnetic induction component 62 can be a reed switch or a magnet used in conjunction with the first magnetic induction component 61. The reed switch controls the on and off of the internal reed through the magnetic effect of the magnet, and realizes connection or disconnection by the approach or distance of the magnet. Preferably, the first magnetic induction component 61 is a magnet, and the second magnetic induction component 62 is a reed switch. The reed switch is arranged on the box body 41 as a fixed side, and the magnet is arranged on the cover body 5 as a movable opening and closing side. When the magnet approaches the reed switch, it can be in a closed state. When the reed switch is in a closed state, the refrigeration module can operate the refrigeration system normally but stop the drainage system, so as to avoid continued drainage when the box body 41 is closed. When the magnet is away from the reed switch, it can be in an open circuit state. When the reed switch is in an open circuit state, the refrigeration module stops operating the refrigeration system but can operate the drainage system normally, so as to avoid hidden dangers caused by continued refrigeration of the refrigeration system when the box body 41 is opened.

[0036] like Figures 2 to 5 as well as Figure 8 As shown, the cover body 5 is detachably connected to the inspection box 4.

[0037] Specifically, in some embodiments, the cover body 5 is a closed cover body used to close the box body 41. Optionally, the cover body 5 can be detachably connected to the inspection box 4 by means of screws, bolts, snap-fit, magnetism, latches, etc. The cover body 5 can further provide shell structure protection for protecting the drain port 2 and the drain seal 3, and can effectively resist the touch and friction generated during the general disassembly and installation of other components, thereby preventing the drain seal 3 from loosening and falling off, causing leakage, dripping or seepage in the refrigeration module, protecting the connection sealing between the drain port and the drain seal, and improving the sealing stability of the drain seal.

[0038] like Figures 1 to 5 As shown, the drain outlet 2 is provided with a drain seal 3 for preventing water leakage.

[0039] Specifically, in some embodiments, the drain seal 3 is a sealing accessory used to prevent water leakage, dripping or seepage from the drain outlet 2. The drain seal 3 has good elasticity and can elastically wrap the outer wall of the drain outlet 2. The elastic contact surface is used to wrap the side wall of the drain outlet to achieve the water-based sealing requirement, thereby avoiding water leakage, dripping or seepage from the refrigeration module. When in use, you only need to manually pull out the drain seal 3 to perform the drainage step. After drainage is completed, cover the drain seal 3 on the drain outlet 2 again, which is convenient for users to use and convenient for maintenance personnel to maintain.

[0040] Optionally, in some embodiments, the drain seal 3 can be made of a material with a certain degree of elasticity such as plastic, rubber, or silicone. The drain seal 3 made of the above material can fit tightly into the gap between the drain outlet and the sink, effectively preventing water leakage or gas backflow, and can also provide more reliable sealing performance to avoid water pollution and the generation of odor; the drain seal 3 can also be made of corrosion-resistant and wear-resistant materials, so that the drain seal 3 has a long service life, can withstand long-term water flow impact and chemical erosion, is not easy to deform or damage, and ensures the durability of the sealed drain outlet.

[0041] like Figure 7 As shown, the drainage seal 3 is provided with an anti-loss structure 31, and the anti-loss structure 31 extends from the outside of the drainage seal 3 toward a direction away from the drainage seal 3, and the inspection box 4 is provided with an anti-loss hole 43 for the anti-loss structure 31 to pass through.

[0042] Specifically, in some embodiments, in order to prevent the drainage seal 3 from being lost or randomly thrown when it is pulled out, an anti-loss structure 31 is extended from the outside of the drainage seal 3 in the direction away from the drainage seal 3, and the inspection box 4 is provided with an anti-loss hole 43 for the anti-loss structure 31 to pass through. The anti-loss structure 31 is used in conjunction with the anti-loss hole 43. When the drainage seal 3 is pulled out, it can be hung on the inspection box 4 through the anti-loss structure 31, and the drainage seal 3 can be covered on the drain outlet 2 after drainage is completed, so as to avoid the drainage seal 3 being lost or misplaced due to being removed and placed elsewhere, thereby avoiding affecting the user's use.

[0043] like Figure 7 As shown, the anti-loss structure 31 is provided with a one-way undercut 32 .

[0044] Specifically, in some embodiments, a one-way undercut 32 is provided at one end of the anti-loss structure 31 away from the drainage seal 3 to prevent the anti-loss structure 31 from loosening from the anti-loss hole 43. Inclined surfaces 321 are provided on both sides of the one-way undercut 32 to facilitate guiding insertion. The inclined surfaces 321 are inclined in a direction away from the drainage seal 3. When the anti-loss structure 31 extends into the anti-loss hole 43, the inclined surfaces 321 on both sides of the one-way undercut 32 are pressed toward the middle and pass through the anti-loss hole 43. When the anti-loss structure 31 is pulled toward the direction of the drainage seal 3 due to external force, the one-way undercut 32 is stuck in the anti-loss hole 43 and cannot be easily pulled out, thereby achieving the effect of preventing the anti-loss structure 31 from loosening from the anti-loss hole 43, thereby avoiding the drainage seal 3 from being lost or lost.

[0045] like Figure 5 , Figure 6 and Figure 8As shown, the cover body 5 is provided with a buckle portion 51 , and the inspection box 4 is provided with a snap-fit ​​portion 42 , and the buckle portion 51 is cooperatively connected with the snap-fit ​​portion 42 .

[0046] Specifically, in some embodiments, the cover body 5 and the inspection box 4 are opened or closed in the form of a snap connection, and the snap portion 51 and the engaging portion 42 are snap recesses opened on the cavity wall of the box body 41. The snap portion 51 is connected with the engaging portion 42, so that the user can easily and conveniently open the cover body 5 for inspection and drainage without using additional fastening accessories, and the effect of quick disassembly and assembly can be achieved, which protects the drain outlet 2 and the drainage seal 3 without affecting the efficiency of disassembling and installing the inspection box 4, simplifies the operating steps, and improves the use efficiency.

[0047] Specifically, in some embodiments, it also includes a raising frame 13 located at the bottom of the refrigeration module, the raising frame 13 is detachably connected to the inner tank mounting frame 12, the inspection box 4 is located between the raising frame 13 and the inner tank mounting frame 12, the raising frame 13 is used to raise the refrigeration module so that there is a certain distance between the refrigeration module and the inner tank mounting frame 12, and the space formed by this distance can be used as a drain port 2, a drain seal 3 and an inspection box 4, so that the drain port 2, the drain seal 3 and the inspection box 4 will not protrude outside the inner tank mounting frame 12, and the layout structure of the refrigeration module is more reasonable.

[0048] like Figures 1 to 8 As shown, a water purification device comprises a refrigeration module as described in any one of the above.

[0049] Specifically, in some embodiments, a water purification device is a device for removing or reducing impurities, particles, odors, tastes and harmful substances in drinking water at home or in the office. The water purification device includes an inner tank module, which is the inner tank of the device used for filtering, heating, sterilizing, disinfecting and other purification steps of the water purification device. The inner tank module includes a refrigeration module specifically used for refrigerating filtered pure water to provide users with low-temperature drinking water with a lower temperature. The refrigeration module is provided with a drainage system for discharging condensed water or idle waste water generated by the internal refrigeration process. An openable and closable inspection box is added to the bottom of the refrigeration module, and a reed switch for controlling the drainage system is provided on the inspection box. The reed switch is triggered by opening the inspection box to control the opening of the drainage system, or the reed switch is triggered by closing the inspection box to control the closing of the drainage system. The reed switch is used to control the start and stop of the drainage system, which is convenient for maintenance personnel to inspect and maintain and increases the frequency of inspection and maintenance.

[0050] Specifically, in some embodiments, a drainage seal for preventing water leakage is added at the drain outlet of the refrigeration module. The drainage seal elastically wraps the outer side of the drain outlet and utilizes the elastic contact surface to wrap the side wall of the drain outlet to achieve the water-based sealing requirement. The drainage seal has a simple structure, the material is easily available, and the manufacturing is convenient. The production cost is low, and it can be used in large quantities for idle wastewater outlets of refrigeration modules of water purification equipment. It has good waterproof practicality and can prevent leakage, dripping or seepage in the refrigeration module. It is convenient for users to use and maintenance personnel to maintain.

[0051] Specifically, in some embodiments, an inspection box and an inspection cover are added at the drain outlet of the refrigeration module to prevent other components from colliding with the drain seal during disassembly and installation, causing the drain seal to loosen and fall off, thereby protecting the sealing of the connection between the drain outlet and the drain seal and improving the sealing stability of the drain seal; the inspection cover is provided with a snap portion for easy disassembly or installation, which is used in conjunction with the snap portion provided on the inspection box, without the need for additional fastening accessories, and can achieve the effect of quick disassembly and assembly.

[0052] like Figures 1 to 5 As shown, it also includes the inner liner mounting frame 12 for installing the refrigeration module, a heightening frame 13 located at the bottom of the refrigeration module and a protection frame 14 for limiting the position of the refrigeration module, the heightening frame 13 is detachably connected to the inner liner mounting frame 12, the inspection box 4 is located between the heightening frame 13 and the inner liner mounting frame 12, and the protection frame 14 is detachably connected to the inner liner mounting frame 12.

[0053] Specifically, in some embodiments, it also includes the inner tank mounting frame 12 for installing the refrigeration module and the protection frame 14 for limiting the position of the refrigeration module. The protection frame 14 is detachably connected to the inner tank mounting frame 12. The protection frame 14 is used to limit the installation position of the refrigeration module and can also protect the refrigeration module from accidental collision with other components. The protection frame 14 can be detachably connected to the inner tank mounting frame 12 by means of threaded connection, snap connection, latch connection and other connection methods, which is convenient for maintenance personnel to disassemble and install the refrigeration module. The protection frame 14 is provided with a plurality of heat dissipation structures for the refrigeration module to dissipate heat. The heat generated by the refrigeration module during the refrigeration process can be dissipated to the outside through the heat dissipation structure. With such a design, the protection frame 14 can not only protect the refrigeration module from accidental collision with other components, but also limit and fix the installation position of the refrigeration module, and also allow the refrigeration module to dissipate heat smoothly by setting the heat dissipation structure.

[0054] like Figures 1 to 8 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0055] Specifically, the reed switch of the sensing mechanism 6 of this embodiment is installed on the box body 41 , and the magnet is installed on the cover body 5 .

[0056] When the user needs to drink cold water, the water purification device is operated so that the inner tank module performs water intake and filtering steps in sequence, and the filtered pure water is input into the refrigeration module through the water inlet 7. After the refrigeration process inside the refrigeration module, it is transported to the next component through the water outlet 8, completing the refrigeration step of the pure water;

[0057] When the refrigeration module needs to discharge the condensed water or idle waste water generated by the internal refrigeration process, the user first opens the liner module and finds the cover 5 at the bottom of the liner mounting frame 12. When the cover 5 covers the inspection box 4, the sensing mechanism 6 forms a powered closed circuit state. In the closed circuit state of the sensing mechanism 6, the refrigeration system operates normally but the drainage system stops operating. The user presses the buckle parts 51 on both sides of the cover 5 by hand to loosen the buckle parts 51 from the engaging part 42 and remove the cover 5. When the cover 5 leaves the inspection box 4, the sensing mechanism 6 is in a powered open circuit state. After the drainage seal 3 is pulled out, the drainage seal 3 is hung on the inspection box 4 through the anti-loss structure 31. At this time, the user can operate the refrigeration module to drain the water. When the sensing mechanism 6 is in the open circuit state, the refrigeration system stops running but the drainage system operates normally. After the condensed water or idle waste water generated by the refrigeration module during the refrigeration process is discharged from the drain port 2, the user reinstalls the drainage seal 3 back to the drain port 2 by hand, presses the buckle parts 51 on both sides of the cover body 5 to reinstall the cover body 5 into the snap-fit ​​part 42 of the inspection box 4, so that the cover body 5 can be smoothly installed into the inspection box 4 to complete the drainage step.

[0058] The specific implementation of Example 2 of the utility model is as follows:

[0059] Different from Example 1, in Example 2, the reed switch of the sensing mechanism 6 is installed on the cover body 5, and the magnet is installed on the box body 41. When the sensing mechanism 6 is in the open circuit state, the refrigeration system runs normally but the drainage system stops running. When the sensing mechanism 6 is in the closed circuit state, the refrigeration system stops running but the drainage system runs normally.

[0060] Specifically, when the cover 5 covers the inspection box 4, the sensing mechanism 6 is in a normally open state. When the sensing mechanism 6 is in an open state, the operation of the drainage system is stopped. The user presses the buckle parts 51 on both sides of the cover 5 by hand to loosen the buckle parts 51 and leave the locking part 42 and remove the cover 5. When the cover 5 leaves the inspection box 4, the sensing mechanism 6 is energized and in a closed state. After the drainage seal 3 is pulled out, the drainage seal 3 is hung on the inspection box 4 through the anti-loss structure 31. At this time, the user can operate the refrigeration module to drain water. The drainage system can operate normally in the closed state of the sensing mechanism 6. After the condensed water or idle waste water generated by the refrigeration module during the refrigeration process is discharged from the drain port 2, the user reinstalls the drainage seal 3 back to the drain port 2 by hand, presses the buckle parts 51 on both sides of the cover 5 to reinstall the cover 5 back to the locking part 42 of the inspection box 4, so that the cover 5 is smoothly installed into the inspection box 4 to complete the drainage step.

[0061] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
