DETAILED DESCRIPTION

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

[0040] At present, the multifunctional water purification equipment for complex water quality has low integration degree, needs complex pipeline wiring and unreasonable layout, which leads to low space utilization, and is difficult to meet the demand of miniaturization of overall structure. Such complex structure of water purification equipment is difficult to be applied to limited space scenes (such as indoor environment), and increases the difficulty of use, installation, debugging and maintenance. Small volume water purification equipment occupies small space, has simple structure but single function. Such simple structure equipment can only deal with basic silt, residual chlorine, peculiar smell and other problems, and cannot effectively deal with heavy metals, bacteria, viruses and other harmful substances in complex water quality, and has poor adaptability.

[0041] It can be seen that there is no new type of water purification equipment with deep purification function and small structure in the current market.

[0042] In addition, under extreme climate conditions, such as water use in cold northern regions or plateau users, water purification equipment faces new challenges, and traditional simple equipment or complex equipment is difficult to ensure normal operation in extreme environment. Therefore, it is also of great significance to provide water purification equipment suitable for plateau areas.

[0043] In view of the above many problems, with reference to Figures 1-6 As shown in the figure, Figure 1 The overall appearance of the anti-freezing purification equipment for maintenance of the utility model is shown in the figure; Figure 2 The overall structure in the heat preservation shell of the utility model is shown in the figure, which shows the overall structure in the heat preservation shell. Figure 3 The structure combination of the multi-stage purification system and the multi-section water storage system of the utility model is shown in the figure, wherein the support frame and the liquid level float ball switch are not shown for clearer understanding.Figure 4 The working principle diagram of the anti-freezing purification equipment convenient for maintenance is shown in the utility model; Figure 5 The structural schematic diagram of the reverse osmosis filter installed on the support frame is shown in the utility model; Figure 6 The structural schematic diagram of the ultrafilter and the storage battery installed on the assembly frame is shown in the utility model.

[0044] The utility model aims at solving above-mentioned problem, please continue to read Figures 1-3 The utility model provides a kind of anti-freezing purification equipment convenient for maintenance, comprising: multistage purification system, including multistage filter, for the multistage filtration of raw water;Multi-section water storage system, including multi-section water reservoir, respectively with the filter in different filter levels, for storing water source after corresponding level filtration;Temperature control assembly, including heat preservation shell 1 and temperature control mechanism, the multistage purification system and the multi-section water storage system are placed in the heat preservation shell 1, and the heat preservation shell 1 is used to prevent heat loss, and the temperature control mechanism is used to raise the temperature in the heat preservation shell 1.

[0045] Specifically, multistage purification system can be understood as the system for gradually purifying water quality, usually by a plurality of same type and / or different type filter communication combination, each filter respectively exert same and / or different filter characteristics.Due to different types of filter have specific function and filter precision, can be handled for different pollutants.Therefore, raw water successively passes through multiple filtration stages, and each filter further removes same kind or different kind of pollutants according to the filter precision corresponding to itself, gradually improves water quality, and copes with various complex water quality to achieve the purpose of depth purification and filtration.

[0046] For example, different types of filter configure different filter material.Filter material type can be adjusted according to water quality, which can be quartz sand, activated carbon and manganese sand and other commonly used filter material.

[0047] Exemplarily, according to the direction of raw water flow, multiple filters can be divided into first-stage filter, second-stage filter, third-stage filter, fourth-stage filter...Nth-stage filter.

[0048] Among them, the type of all filters in multistage filter can be different, suitable for layer-by-layer depth purification of multiple pollutants.

[0049] Among them, the type of at least one filter in multistage filter is the same but not all the same.Usually, multiple same filters are cascaded to enhance specific filter effect, improve the effect of single function and prolong the service life of equipment.

[0050] In actual application, it can be configured as same or different filter characteristics in multistage filter according to demand.

[0051] Specifically, the multi-stage water storage system includes multiple water storage tanks, and multiple filters of the same type and / or different types are connected to different stages of the water storage tanks, so that the water source is filtered at different levels and then enters different water storage tanks, and each stage of the water storage tank stores water filtered at different levels.

[0052] In some embodiments, the multi-stage filter and the multi-stage water storage tank have a one-to-one or multiple-to-one quantity relationship.

[0053] In some embodiments, each stage of the water storage tank can be connected to each level of the filter, and the raw water is filtered by the current level of the filter and then enters the corresponding water storage stage. Specifically, the external water source (using a well pump to pump water or an external water tank to enter water) is first stored in the first stage of the water storage tank (raw water tank 7), then enters the first level of the filter for primary filtration, the water after primary filtration is stored in the second stage of the water storage tank, then enters the second level of the filter for intermediate filtration, the water after intermediate filtration is stored in the third water storage tank, then enters the next level of the filter for further filtration, until the final deep purified water is stored in the last stage of the water storage tank. Therefore, the water filtered at each level is independently stored in the corresponding stage of the water storage tank as a backup, and the water quality and storage of each filtration stage can be monitored and managed separately, facilitating maintenance and adjustment.

[0054] In some embodiments, each stage of the water storage tank can be connected to at least one level of the filter, and the raw water is filtered by the current level, two levels or more levels of the filter and then enters the corresponding water storage stage. For example, the external water source (using a well pump to pump water or an external water tank to enter water) is first stored in the first stage of the water storage tank (raw water tank 7), then enters the first level of the filter and the second level of the filter in turn for two-stage filtration, the water after two-stage filtration is stored in the second stage of the water storage tank, then enters the third level of the filter or more levels of the filter for deep filtration, the water after deep filtration is stored in the third stage of the water storage tank, then enters the next level of the filter or more subsequent levels of the filter for final filtration, until the final deep purified water is stored in the last stage of the water storage tank. Therefore, multiple levels of filters can be connected to the same water storage tank, simplifying the device structure, reducing the cost and complexity of the device, and saving space.

[0055] In some embodiments, each stage of the water storage tank is connected to the corresponding level of the filter, and when the water source is filtered by the corresponding level, it is directly stored in the corresponding water storage tank, and each stage of the water storage tank can be provided with a water outlet pipeline, so that users can select water from different water storage tanks according to actual needs to meet different purposes.

[0056] For example, the water after primary filtration can be used for cleaning and flushing or for equipment cooling or cleaning. The raw water can be directly used as domestic water through the raw water pipeline.

[0057] The water filtered by the intermediate filter is suitable for kitchen cleaning, irrigation, or washing, or for use in a production line.

[0058] The water filtered by the deep filter is the water in the last-stage water storage tank, which can be used as purified water and is suitable for drinking or cooking.

[0059] Therefore, the user can select different levels of water sources according to needs, without the need for all water to be deeply purified, saving filter resources.

[0060] In this embodiment, only the last-stage water storage tank is provided with a water outlet pipeline, and the raw water filtered by the multi-stage purification system is converted into purified water and directly supplied to the user's household in the plateau area.

[0061] As a further illustration of this embodiment, the winter temperature in the plateau area is low throughout the year, and the day-night temperature difference is large. In a low-temperature environment, the water inside the water purification equipment is prone to freezing, causing the filter, filter membrane, pipeline, valve, and other components to crack, affecting the normal use of the equipment. Therefore, a temperature control assembly is designed specifically for this purpose.

[0062] The temperature control assembly is composed of a heat preservation shell 1 and a temperature control mechanism. The multi-stage purification system and the multi-stage water storage system are both installed inside the heat preservation shell 1 and arranged close to the temperature control mechanism. The heat preservation shell 1 can be made of heat insulation material to reduce heat loss during equipment operation and improve energy utilization efficiency.

[0063] The temperature control mechanism can monitor the temperature inside the equipment through built-in sensors and ensure the normal operation of the equipment in cold environments through heating elements or other equipment. Therefore, it is particularly suitable for use in cold northern regions. Even in extremely cold environments below zero degrees, the equipment can still operate efficiently and stably, avoiding downtime and damage risks, and improving the reliability of the equipment.

[0064] Therefore, this equipment integrates multi-stage filtration, multi-stage water storage, and heat preservation functions, ensuring that the equipment can operate normally in complex water quality treatment and cold environments, expanding user experience and market promotion in different application scenarios such as household scenarios, commercial scenarios, and cold scenarios, meeting the demand for high-quality water sources, while reducing the frequency of equipment replacement, achieving a balance between economy and efficiency. The overall design is compact and functional, and the equipment can provide efficient and stable water purification solutions in households, businesses, and cold environments, significantly improving the market competitiveness of the product and meeting the demand for drinking water in diverse scenarios.

[0065] In some embodiments, the heat preservation shell 1 can be provided separately without the temperature control mechanism.

[0066] In some embodiments, the front of the heat preservation shell 1 is provided with an openable protective door, which can open the heat preservation shell 1 to disassemble and replace the filters inside the heat preservation shell 1, suitable for long-term use in limited space environments.

[0067] Preferably, the multi-stage filter includes at least two of the quartz sand filter 3, the activated carbon filter 4, the ultrafilter 5, and the reverse osmosis filter module 6. In the present embodiment, two-stage filters, three-stage filters, and four-stage filters can be selected. Among them, different combinations can be selected according to the specific water purification needs and water quality conditions to adapt to various market needs such as families, offices, agriculture, and industry, thereby improving the water purification efficiency while giving consideration to cost control, expanding adaptability, and application prospects.

[0068] For laboratory water, domestic water, or general commercial water, when designing a multi-stage filter, considering the balance between purification effect, cost-effectiveness, volume, ease of installation and maintenance, and the diversity of applicable water quality, it is generally appropriate to design four different types of filters.

[0069] Please continue to refer to Figure 3 and Figure 4 , and the following will take the preferred four-stage filter as an example:

[0070] The four-stage filter can include:

[0071] The quartz sand filter 3 (first stage): The quartz sand filter 3 is a coarse filter module for removing impurities such as silt, large particle suspended matter, and rust in water.

[0072] The activated carbon filter 4 (second stage): removes odors, residual chlorine, and organic matter, etc. For example, using activated carbon as the filter core to further purify the water after coarse filtration.

[0073] The ultrafilter 5 (third stage): The ultrafilter 5 can filter out bacteria, colloids, and other small particle microorganisms in water, further removing microorganisms from the water quality.

[0074] The reverse osmosis filter module 6 (RO membrane, fourth stage): used for deep purification to remove dissolved inorganic salts, heavy metals, and other small pollutants, achieving complete purification and ensuring that the final output water quality meets high-purity standards, suitable for drinking water needs.

[0075] In some embodiments, if the purification effect of the four-stage filter does not meet the ideal demand, a manganese sand filter can be added at the front end or an aeration facility can be added as appropriate, and an ultraviolet disinfection lamp can be added at the rear end.

[0076] Specifically, the multi-stage water storage system is provided with an ultraviolet disinfection lamp and a water meter on the corresponding connected water outlet pipe. In the present embodiment, the water meter is generally installed at the water outlet of the equipment, for example, at the position of the water outlet of the last set of water purification tank 9. Correspondingly, the water meter can be installed at the position of the raw water outlet of the raw water pipeline.

[0077] In some embodiments, the water meter can also be replaced by other water quantity monitors.

[0078] The ultraviolet disinfection lamp can be installed in the water purifying tank 9 or the rear end of the water outlet pipeline of the water purifying tank 9 to further kill microorganisms, bacteria and viruses in the water to meet the high-standard water purification requirements.

[0079] Correspondingly, the ultraviolet disinfection lamp can be installed at the rear end of the raw water pipeline.

[0080] Preferably, the multi-stage water storage system includes at least two of the raw water tank 7, the buffer tank 8 and the water purifying tank 9. In combination with the above embodiments, the raw water tank 7 is used as the first-stage water storage system to first receive raw water, the water purifying tank 9 is used as the last-stage water storage system to output purified water, and the buffer tank 8 is arranged between the raw water tank 7 and the water purifying tank 9 and is connected to the two tanks through a pre-set stage of filters. For example, the buffer tank 8 can be arranged between the quartz sand filter 3 and the activated carbon filter 4, or between the activated carbon filter 4 and the ultrafilter 5, or between the ultrafilter 5 and the reverse osmosis filter module 6.

[0081] In the present embodiment, the quartz sand filter 3, the activated carbon filter 4, the ultrafilter 5 and the reverse osmosis filter module 6 are sequentially connected in the direction of raw water flow, and the raw water tank 7, the buffer tank 8 and the water purifying tank 9 are sequentially connected in the direction of raw water flow. The raw water tank 7 is connected to the quartz sand filter, the activated carbon filter 4 and the ultrafilter 5 in sequence, the ultrafilter 5 is connected to the buffer tank 8, the buffer tank 8 is connected to the reverse osmosis filter module 6, and the reverse osmosis filter module 6 is finally connected to the water purifying tank 9. The water purifying tank 9 is provided with a water outlet for outputting purified water.

[0082] Please continue to refer to Figure 4 Therefore, the external water source (water pumped by a well pump or water from an external water tank) is stored in the raw water tank 7 or directly used as domestic water. The raw water in the raw water tank 7 is gradually purified by the quartz sand, activated carbon and ultrafilter 5 and then stored in the buffer tank 8 for standby use. The water is then filtered by the reverse osmosis filter module 6 and enters the water purifying tank 9. The water purifying tank 9 outputs purified water, thereby achieving multi-stage filtration.

[0083] Therefore, in the present embodiment, the three-stage water storage system is correspondingly connected to the four-stage filter to comprehensively purify complex water quality through multi-stage filtration, while simplifying the structure and reducing the maintenance cost, thereby solving the contradiction between the structure and function of the traditional equipment. The compact arrangement can also optimize the pipeline, reduce the occupied area, and cooperate with the temperature control assembly to ensure stable operation of the equipment in a severe cold environment.

[0084] In a further technical solution, the multi-stage purification system and the multi-stage water storage system are arranged longitudinally and side by side, and the multi-stage filters are arranged horizontally adjacent to each other, and the multi-stage water storage systems are arranged horizontally overlapping and vertically spaced to form a pipe space 16.

[0085] As an illustration of the present solution, a three-stage water reservoir and a four-stage filter are taken as an example.

[0086] The quartz sand filter 3, the activated carbon filter 4, the ultrafilter 5 and the reverse osmosis filter module 6 are arranged in a row in front of the raw water tank 7, the buffer tank 8 and the purified water tank 9. The longitudinal side-by-side structure makes the water flow forward through each filter and then enter the corresponding water reservoir. The flow path is simple, and the length and complexity of the pipeline are reduced.

[0087] The four-stage filters in the front row are arranged in close proximity in the transverse direction, which is compact in structure and suitable for use in environments with limited space. Specifically, the ultrafilter 5, the quartz sand filter 3, the activated carbon filter 4 and the reverse osmosis filter module 6 are arranged in the transverse direction from left to right. Therefore, the quartz sand filter 3 and the activated carbon filter are located in the middle of the device, which can ensure that the center of gravity of the product is not deviated. At the same time, the reverse osmosis filter module 6 as the last stage filter is located at the edge of the device, which is convenient for designing the water outlet pipeline to output purified water.

[0088] Of course, the positions of the quartz sand filter 3 and the activated carbon filter 4 can be interchanged.

[0089] In some embodiments, a battery 15 can be arranged below the ultrafilter 5 on the left side to form a longitudinal arrangement of the ultrafilter 5 and the battery 15, further improving the space utilization.

[0090] The three-stage water reservoir in the rear row is arranged with the raw water tank 7 at the bottom and the buffer tank 8 and the purified water tank 9 arranged in the transverse direction. This arrangement reduces the space occupation and saves the ground space by arranging the buffer tank 8 and the purified water tank 9 above the raw water tank 7. In addition, the buffer tank 8 and the purified water tank 9 below and the raw water tank 7 above are spaced apart in the vertical direction to form a pipe running space 16. Therefore, the device provides an independent pipe running space 16, which is convenient for pipeline layout and maintenance and disassembly of the pipeline.

[0091] Optionally, the length of the raw water tank 7 is preferably the same as that of the buffer tank 8 and the purified water tank 9, so as to form a compact rectangular plate structure as a pipe running space 16.

[0092] Therefore, the reasonable arrangement of the multi-stage purification system and the multi-stage water storage system makes the overall structure compact and easy to disassemble and assemble, which is convenient for use in space-limited environments, such as indoor environments as small water purification devices, and has low difficulty in use, installation, debugging and maintenance.

[0093] Further, the purified water tank 9 and the raw water tank 7 are connected by an overflow pipe 11. Therefore, the purified water tank 9 is directly connected to the raw water tank 7 through the overflow pipe 11, which can optimize the space layout and reduce the pipeline.

[0094] It can be understood that the device is usually provided with a support frame 12. The raw water tank 7, the buffer tank 8 and the purified water tank 9 are fixed on the support frame 12 in the above-mentioned arrangement. At the same time, the quartz sand filter 3, the activated carbon filter 4, the ultrafilter 5 and the reverse osmosis filter module 6 are also arranged on the support frame 12 through corresponding connecting pieces.

[0095] Further, please refer to Figure 5 , when the reverse osmosis filter module 6 is arranged on the support frame 12 through corresponding connecting pieces, it can be fixed on the support frame 12 through two staggered reverse osmosis filters 61. Specifically, the staggered arrangement can utilize the arc of the cylindrical appearance of the reverse osmosis membrane shell of the reverse osmosis filter 61, and has a distance in both the horizontal direction and the vertical direction, arranged in a diagonal line, thus reducing the horizontal distance of assembly. At the same time, in the vertical direction, the heights are different, which is beneficial to the disassembly and maintenance of the two reverse osmosis membrane shells.

[0096] Further, please refer to Figure 6 , the height of the ultrafilter 5 is shorter than that of the other filters. Therefore, the space remaining when the ultrafilter 5 is fixed on the support frame 12 can be utilized. When the ultrafilter 5 is arranged on the support frame 12 through corresponding connecting pieces, the connecting pieces can be an assembly frame 17 composed of an upper connecting frame and a lower connecting frame. The lower connecting frame is a rectangular hollow shape with two open sides, which is used to place the power supply system. The upper connecting frame is an angular hollow shape with three open sides, which is used to install the ultrafilter 5. Therefore, the bottom of the front row of the assembly frame 17 is fixed with the battery 15, the top right side is screwed with the ultrafilter 5, and the whole is placed on the left side of the front row where the multi-stage purification system is installed, which is convenient for the wiring of pipelines and lines.

[0097] In this embodiment, the small water purification device is suitable for indoor use. In other embodiments, it can also be used in outdoor environment, and a protective steel shed can be built and the capacity of the battery 15 can be increased for power supply.

[0098] As an explanation of this embodiment, the power supply system is connected with the temperature control mechanism, which can provide power for the temperature control system and maintain the normal operation of the temperature control system.

[0099] In some embodiments, the power supply system can be a battery 15, which can be connected to the national power grid.

[0100] In some embodiments, the power supply system can be a photovoltaic-inverter-battery 15 system, which utilizes photovoltaic power supply.

[0101] This embodiment is used to further illustrate the temperature control assembly.

[0102] For the heat preservation shell 1, the heat preservation shell 1 is made of a low thermal conductivity material configured to maintain the temperature inside the heat preservation shell 1. Therefore, the heat preservation shell 1 is made of a low thermal conductivity material, which can effectively slow down the heat from the outside or from the inside, and plays a role of heat insulation and heat preservation.

[0103] For example, polyurethane insulation boards can be spliced into the heat preservation shell 1, or polyurethane foaming material can be used as a filling layer.

[0104] In some embodiments, polystyrene, glass wool, rock wool, vacuum insulation board, etc. can be used as the heat preservation shell 1.

[0105] For the temperature control mechanism, the temperature control mechanism includes: a temperature control probe located in the heat preservation shell 1;

[0106] A heating device is arranged in the heat preservation shell 1; a temperature control switch is connected with the temperature control probe and the heat tracing band respectively; wherein the temperature control switch is used to receive the temperature information collected by the temperature control probe, and control the start and stop of the heat tracing band.

[0107] In the embodiment, the temperature control probe is located in the heat preservation shell 1, which is used to detect the temperature inside the device in real time. The temperature control probe is connected with the temperature control switch, and can transmit the real-time detected temperature information to the temperature control switch. The heating device can be a heat tracing band or a carbon crystal plate, etc. The heat tracing band can be spirally arranged on the support frame 12 in the heat preservation shell 1 from the bottom. For example, the winding and binding method or the binding method along the frame can be selected for fixation. The carbon crystal plate heating sheet can be attached to the bottom of the device.

[0108] The temperature control switch controls the start and stop of the heat tracing band by monitoring the real-time temperature inside the device. When the heat tracing band is started, heat can be generated to raise the temperature inside the shell. Therefore, the internal temperature can be maintained within a set range in a low temperature environment, and the device can be normally operated under low temperature conditions.

[0109] In some embodiments, the temperature control probe is placed in the middle of the device and is suspended, and is kept at a certain distance from the heat tracing band.

[0110] In some embodiments, the power and length of the heat tracing band can be determined according to the actual size and capacity of the device, which is not limited in the embodiment.

[0111] Specifically, the temperature control mechanism is used to control the temperature in the heat preservation shell 1 to be not lower than a preset value. The upper and lower limits of the preset temperature range in the temperature control switch are, for example, -0.5℃ and 2℃. After detecting the temperature each time, the temperature control switch determines whether the current temperature is out of the set range. When the temperature collected by the temperature control probe is lower than -0.5℃, the temperature control switch controls the heating band to start working to heat the inside of the equipment. When the temperature control band starts to work, the temperature gradually rises. When the temperature in the equipment rises to above 2℃, the temperature control switch automatically cuts off the power supply of the heating band to stop heating.

[0112] Further, in combination with the heat preservation effect of the heat preservation shell 1, the temperature loss of the water purification equipment in a low-temperature environment is reduced. If the internal temperature gradually decreases to a temperature value lower than -0.5℃, the temperature control switch restarts the heating band.

[0113] Therefore, the temperature control system has an automatic adjustment function, can automatically start or stop the heating action of the heating device according to the actual temperature change, does not need manual intervention, and is convenient to use. The heating device is started only when necessary, avoiding energy consumption caused by continuous heating, while ensuring that the temperature is maintained in an appropriate range, and ensuring that the equipment can operate stably for a long time in a cold environment.

[0114] In further technical solutions, at least one of the filters and / or at least one of the water reservoirs is respectively provided with a valve and a water pump on the corresponding pipeline; and each of the water reservoirs is provided with a plurality of liquid level float ball switches 10 arranged vertically and spaced apart.

[0115] In this embodiment, the valves are arranged on the pipelines connecting the filters and the water reservoirs, or on the pipelines connecting the multi-stage filters, or on the front and rear pipelines of each water reservoir, so that the water flow can be closed or opened in different situations. The positions and numbers of the valves can be configured according to specific use conditions to achieve flexible control of the water outlet direction and flow path.

[0116] In combination with the above embodiments, the water inlet pipeline and the water outlet pipeline need to pass through the heat preservation shell 1, and the pipelines can be connected by punching holes at corresponding positions of the heat preservation shell 1 according to the positions of the water inlet, the water outlet, and the sewage outlet.

[0117] In some embodiments, the holes after the connection of the pipelines can be filled with heat preservation sealant for sealing treatment.

[0118] Preferably, the water inlet pipe connected to the water inlet, the sewage discharge pipe connected to the sewage outlet, and the overflow pipe are arranged on the left side of the front row, which facilitates unified treatment. The two water supply pipes (the water outlet pipeline connected to the water inlet and the raw water pipeline directly discharging raw water) are arranged on the right side, which facilitates use.

[0119] Of course, adjustments can be made according to actual conditions.

[0120] Specifically, water pumps are added to part or all of the pipelines to make the water to be filtered smoothly pass through the multi-stage filter and flow into the multi-section water reservoir.

[0121] For example, the raw water pump 13 can be arranged on the pipeline of the raw water tank 7 to deliver the water source to the multi-stage purification system in the initial stage. The booster pump 14 is arranged on the outlet pipeline of the purified water tank 9 and is used to output the purified water to the user end.

[0122] More specifically, each section of the water reservoir is equipped with multiple liquid level float ball switches 10 and is installed at equal intervals at different heights to detect different water levels and monitor the liquid level of the water reservoir in real time, so as to timely manage the water quantity.

[0123] Among them, the multiple liquid level float ball switches 10 are assembled to the corresponding water reservoirs by means of blind plate quick connection.

[0124] In the related art, the external components such as the liquid level float ball switch 10 need to be assembled and disassembled by screwing the fixing nuts from the inside and outside. If the assembly position in the water tank is too high or the equipment is located in a narrow space, manual disassembly will be very inconvenient. Therefore, the embodiment re-installs the float ball switch by means of blind plate quick connection, so that it can be conveniently disassembled and assembled from the outside, which is convenient for subsequent maintenance and replacement. The blind plate quick connection is achieved by a quick connector. The structure and function of the quick connector have been separately applied in another patent, so this application will not be described in detail. The quick connector is used to achieve the convenient disassembly and assembly of the liquid level float ball switch 10.

[0125] In a preferred embodiment extending from the embodiment, the device further comprises a power distribution cabinet 2 arranged on the heat preservation shell 1. As shown in Figure 1 The power distribution cabinet 2 is preferably arranged on the outer side wall surface of the heat preservation shell 1.

[0126] It should be understood that, similar to the conventional water purification equipment, the power management system of the power distribution cabinet 2 is directly connected to the external power supply and can realize the switching between automatic and manual control modes. The power distribution cabinet 2 is connected to the external power supply, and the power supply is provided to all control equipment, including the deep well pump, the raw water pump 13, the booster pump 14, and various sensors (such as the liquid level float ball switch 10). In the automatic mode, the water level changes in the three water tanks are monitored by the electric control module and the sensor system (such as the liquid level float ball switch 10), and the corresponding water pump is automatically started or stopped, and the state is displayed through the corresponding indicator light. In the manual mode, each device is controlled by manual control, and is directly started or stopped through the manual switch of each device. The manual and automatic operations are usually realized through the switching switch in the power distribution cabinet 2, and the specific structure of the power distribution cabinet 2 will not be described in detail in this embodiment. For the power distribution cabinet 2, the improvement of this embodiment is that the power distribution cabinet 2 is externally arranged, which is convenient to operate and is more convenient for reasonable wiring.

[0127] Similarly, the switch corresponding to the integrated heating device of the power distribution cabinet 2 can manually control the operation of the heating device, or display the start-stop state of the heating device in an automatic mode.
