Description

Technical Field

[0001] The invention relates to the technical field of water purifier design, and in particular to an all-in-one water purifier and quick-heating drinking water machine. Background Art

[0002] Household water purifiers, also known as all-in-one water purification and quick-heating drinking water machines, are usually pure water production equipment that integrates a filter element and a quick-heating device. They are used to purify, filter and heat raw water, provide hot and cold drinking water, and meet people's daily needs.

[0003] A household water purifier usually includes an outer shell, a raw water tank, a self-priming pump connected to the raw water tank, a fully composite filter element connected to the self-priming pump, a pure water tank connected to the fully composite filter element, a water pump connected to the pure water tank, a water vapor separation box connected to the water pump, and a rapid heating control module arranged between the water pump and the water vapor separation box and heating the pure water. The rapid heating control module includes a rapid heating device, a controller and a power adapter. A flushing valve is also connected between the fully composite filter element and the raw water tank, and the waste water in the fully composite filter element is re-injected into the raw water tank through the flushing valve.

[0004] Among them, the water vapor separation box is an existing technology, and the specific structure will not be repeated. The water vapor separation box is to prevent high-temperature steam from directly spraying out when hot water is discharged and causing scalding to the user. Therefore, a water vapor separation box is used at the hot water outlet of the water purifier to achieve the purpose of separating water vapor and reducing high-temperature steam at the outlet.

[0005] At the same time, an inlet temperature sensor connected to the controller signal is arranged at the water inlet of the quick heating device, and an outlet temperature sensor connected to the controller signal is arranged at the water outlet of the quick heating device. The quick heating device is electrically connected to the controller and the heating power of the quick heating device is usually constant. The water pump is an electromagnetic water pump and is connected to the controller signal.

[0006] At present, a Chinese patent with publication number CN207760171 and publication date of August 24, 2018 discloses a water purifier, including a shell, a raw water tank, a pure water tank and a control chip. An L-shaped waterway plate with a plurality of water inlets and outlets is connected between the raw water tank and the pure water tank, respectively forming a raw water waterway. The water outlet of the raw water tank is connected to the raw water inlet of the L-shaped waterway plate through a pipeline, and the pipeline is connected to a one-way valve; the raw water outlet of the L-shaped waterway plate is connected to a water purification module with a plurality of filter elements through a pipeline, and a self-priming booster pump is connected in the pipeline.

[0007] The layout of the components of this type of water purifier means that when the whole machine is assembled, the components are usually fixed together by bolts, so the efficiency of the whole machine assembly is relatively low. Summary of the invention

[0008] The object of the present invention is to provide an all-in-one water purifier and quick-heating drinking water machine, which can optimize the layout of the whole machine and thus improve the efficiency of the assembly of the whole machine.

[0009] The above technical objectives of the present invention are achieved through the following technical solutions: a water purifier and quick-heating drinking water machine, comprising an outer shell, a raw water tank, a self-priming pump, a fully composite filter element, a pure water tank, a water pump, a water vapor separation box located on the pure water tank, and a quick heating control module, the quick heating control module comprises a quick heating device, a controller and a power adapter, a flushing valve is also connected between the fully composite filter element and the raw water tank, and also comprises a main bracket, the main bracket comprises a first mounting portion located in the middle of the main bracket and in a cylindrical shape for embedding the fully composite filter element, a second mounting portion located at the rear side of the main bracket and for supporting the raw water tank, a third mounting portion opened in the second mounting portion and for embedding the self-priming pump, a fourth mounting portion located on both sides of the first mounting portion and for installing the pure water tank, a fifth mounting portion located at the lower side of the fourth mounting portion and for installing the water pump and the quick heating control module, and the flushing valve is installed in the second mounting portion.

[0010] By adopting the above scheme, the main bracket provides embedding of the full composite filter element through the first mounting part, the second mounting part provides support for the raw water tank, the third mounting part provides embedding of the self-priming pump, the fourth mounting part provides installation of the pure water tank, and the fifth mounting part provides installation of the water pump and the rapid heating control module. At this time, each position on the main bracket can correspond to different components respectively, so that the various components can be reasonably arranged on the main bracket, and finally the various components can be efficiently assembled; there is no need to fix the various components to each other with bolts.

[0011] The present invention is further configured as follows: a mounting frame is detachably connected to the main bracket, the water pump, quick heating device, controller and power adapter are all arranged on the mounting frame, a water inlet temperature sensor connected to the controller electrical signal is arranged at the water inlet of the quick heating device, a water outlet temperature sensor connected to the controller electrical signal is arranged at the water outlet of the quick heating device, and the water pump is connected to the controller electrical signal to control the pumping power of the water pump.

[0012] By adopting the above scheme, since in the prior art, after the water purifier is assembled except for the outer shell part, it is necessary to transport the entire water purifier to a test site to test whether the heating function of the water purifier can be used normally; the test principle is: when setting the output hot water temperature, if the water temperature at the water outlet of the quick heating device is too high, the water outlet temperature sensor transmits an electrical signal to the controller, and the controller controls the water pump to increase the water flow rate, thereby reducing the water outlet temperature; if the water outlet temperature of the quick heating device is too low, the water outlet temperature sensor transmits an electrical signal to the controller, and the controller controls the water pump to reduce the water flow rate, thereby increasing the water outlet temperature;

[0013] However, due to the large size and weight of the water purifier, it is time-consuming and laborious to transport the whole machine to the test site; and during the test, all parts of the whole machine except the outer shell need to be assembled, which further affects the efficiency of the test;

[0014] At this time, by installing the water pump, quick heating device, controller and power adapter on the mounting frame which is detachably connected to the main bracket, it is only necessary to transport the mounting frame assembled with the water pump, quick heating device, controller and power adapter to the test site, so as to quickly and conveniently test the heating function of the water purifier. Compared with the transportation of the whole water purifier, the weight and volume can be reduced, which is beneficial to improve the efficiency of water purifier testing. During the test, it is only necessary to connect the water pump to the external water tank for testing.

[0015] The present invention is further configured as follows: a support platform is provided on the main bracket and located on the upper side of the second mounting part, an arc-shaped groove for the first mounting part to be embedded is provided on the side wall of the raw water tank, an annular platform that abuts against the upper end of the first mounting part is integrally provided on the inner wall of the upper end of the arc-shaped groove, the annular platform is C-shaped, and a first limiting ring embedded in the inner side of the first mounting part is integrally provided at the lower end of the annular platform, a C-shaped annular groove is also provided on the peripheral side of the support platform, and a connecting ring embedded in the annular groove is integrally provided on the peripheral side of the lower end of the raw water tank.

[0016] By adopting the above scheme, when the raw water tank needs to be installed on the support platform, the second installation part on the main bracket is used, and the second installation part can be inserted into the full composite filter element or embedded in the arc-shaped groove of the raw water tank, wherein the raw water tank is placed on the support platform from top to bottom, and the ring platform at the upper end of the arc-shaped groove can abut against the upper end of the second installation part, and the first limiting ring on the ring platform is embedded in the inner side of the second installation part, and the upper end of the second installation part can be inserted between the first limiting ring and the arc-shaped groove, so that the first layer of limiting effect can be formed on the raw water tank;

[0017] At the same time, an annular groove is opened on the side of the support platform, and the connecting ring at the lower end of the raw water tank can be embedded in the annular groove, so that the second layer of limiting effect on the raw water tank can be formed through the annular groove and the connecting ring; at this time, the installation of the raw water tank on the support platform can be completed, and the whole installation process is very convenient and fast, and a relatively stable limiting function is formed for the raw water tank, and finally the installation of the raw water tank on the second installation part can be realized relatively quickly and stably.

[0018] The present invention is further configured as follows: a quick-plug water outlet seat assembly is arranged on the raw water tank, and the quick-plug water outlet seat assembly includes two one-way leak-proof valves located at the lower end of the raw water tank, and two water outlet seat bodies located on the second mounting portion and corresponding to the two one-way leak-proof valves respectively; the water outlet seat body includes a seat body, a fixing sleeve integrally arranged at the lower end of the seat body, a flow channel integrally arranged in the fixing sleeve, a connecting portion detachably connected to the seat body, a cavity layer opened in the connecting portion and communicating with the flow channel, a one-way check valve arranged in the cavity layer, and a A connecting ring platform, a connecting ring groove provided on the upper side of the connecting ring platform, and a rubber ring embedded in the connecting ring groove. The second mounting portion is integrally provided with a positioning sleeve for the fixing sleeve to be embedded in and connected to the self-priming pump. The support platform is pressed against the rubber ring. The one-way check valve includes a sleeve body, a valve stem located in the sleeve body and the upper end of which is pressed against by the one-way leak-proof valve, a rubber sealing ring located at the lower end of the valve stem and pressed against the end surface of the lower end of the sleeve body, and a reset spring sleeved on the valve stem and located in the sleeve body. A first through hole is provided on the support platform for the one-way leak-proof valve to be embedded in and pressed against the upper end of the valve stem.

[0019] By adopting the above scheme, when the water outlet seat body needs to be installed, the positioning sleeve integrally provided on the main bracket can be used to allow the fixing sleeve of the water outlet seat body to be embedded in the positioning sleeve, and at the same time, the upper end of the positioning sleeve is pressed against the lower end of the seat body, and the assembly of the water outlet seat body on the main bracket can be quickly completed at this time; wherein the support platform is pressed against the rubber ring, thereby improving the sealing performance of the water outlet seat body when it is installed on the main bracket;

[0020] When the raw water tank is plugged into the support platform, the one-way leak-proof valve at the lower end of the raw water tank can be pressed against the valve stem of the one-way check valve, and then the valve stem of the one-way check valve can be moved downward. At the same time, the reset spring undergoes elastic deformation, and the rubber sealing ring can be moved away from the end face of the sleeve body by one end. At this time, the one-way check valve can be in an open state; the water in the raw water tank can enter the positioning sleeve through the flow channel, thereby completing the water inlet.

[0021] The present invention is further configured as follows: a water outlet is provided at the lower end of the raw water tank and at a position corresponding to the one-way leak-proof valve, the one-way leak-proof valve comprises a rod body, a return spring sleeved on the rod body, an insertion end located at the upper end of the rod body and inserted into the water outlet, an end plate located at the lower end of the rod body and pressed against the lower end of the return spring, a push rod located at the lower end of the end plate and used to press against the upper end of the valve stem, a silicone sealing sleeve is sleeved on the insertion end, the silicone sealing sleeve comprises a first ring body connected to the peripheral side of the insertion end, a second ring body located on the upper side of the first ring body and in a trumpet shape opening upward, and a third ring body located on the upper side of the second ring body, a first sealing groove for the first ring body to be embedded is provided on the inner wall of the water outlet, a second sealing groove is provided on the inner wall of the water outlet and located on the upper side of the first sealing groove, and the second sealing groove is in a trumpet shape opening upward.

[0022] By adopting the above scheme, when the raw water tank is installed on the support platform, the push rod at the lower end of the one-way leak-proof valve is pressed against the valve stem in the one-way check valve, so the rod body is also pushed upward by the valve stem, and the return spring is elastically deformed. At this time, the first ring body of the silicone sealing sleeve is separated from the first sealing groove, and the second sealing groove is separated from the second ring body of the silicone sealing sleeve. Therefore, the water in the raw water tank can be discharged from the water outlet and enter the one-way check valve, and flow out from the flow channel of the water outlet seat body;

[0023] When the raw water tank is removed from the second mounting part, the return spring elastically recovers, and the elastic recovery force can push the rod body downward, and then the first ring body on the silicone sealing sleeve can be embedded in the first sealing groove and pressed against the inner wall of the first sealing groove, and the first ring body and the first sealing groove can form a first layer of seal; at the same time, the second ring body of the silicone sealing sleeve presses against the second sealing groove, and the second ring body and the second sealing groove can form a second layer of seal; such a double sealing structure can effectively stop leakage.

[0024] The present invention is further configured as follows: a limiting sleeve is integrally provided on the outer wall of the lower end of the raw water tank and located on the peripheral side of the water outlet and is embedded in a rubber ring after passing through the first through hole; a damping portion is integrally provided on the inner side of the rubber ring and is pressed against the outer wall of the limiting sleeve after deformation; an internal thread is provided on the inner wall of the seat body, and an external thread is provided on the outer wall of the connecting portion and is threadedly connected to the internal thread.

[0025] By adopting the above solution, when the raw water tank is installed on the support platform, the limiting sleeve can be inserted into the rubber ring after passing through the first through hole. By utilizing the damping part integrally provided on the inner side of the rubber ring, the damping part can be pressed against the outer wall of the limiting sleeve after elastic deformation. At this time, a large friction damping force is generated between the damping part and the limiting sleeve, which is ultimately conducive to the stable installation between the raw water tank and the support platform.

[0026] By using the internal thread on the inner wall of the seat body and the external thread on the outer wall of the connecting part which is threadedly connected to the internal thread, a detachable connection between the seat body and the connecting part can be achieved, thereby facilitating the disassembly, assembly and replacement of the one-way check valve.

The waste water generated after filtration by the intermediate membrane filter element flows from between the central sleeve and the peripheral side of the clean water discharge pipe, from the peripheral sides of the main drain pipe and the clean water discharge pipe, and then enters the waste water Discharge channel; the filter bottle is provided with a first check valve for preventing backflow at the second water outlet of the bottom cover, and the fourth water outlet of the intermediate membrane end cover is provided with a second check valve for preventing the discharge of clean water filtered through the intermediate membrane; when the filter element seat is installed on the filter bottle, the filter element seat drives the clean water discharge pipe to move upward and then opens the second check valve, and the clean water discharge channel is provided with a third check valve for preventing the backflow of discharged waste water; a plug-in end is formed on the top cover, which is plugged into the upper end of the center sleeve and allows the upper end of the intermediate membrane filter element to be embedded, and a positioning end is formed on the top cover, which is located in the center of the center sleeve and plugged into the end face of the intermediate membrane filter element; an annular scale inhibitor bag located at the third water outlet and the top of the intermediate membrane filter element is sleeved in the plug-in end.

[0028] By adopting the above scheme, the annular PP cotton coarse filter layer, the annular activated carbon filter layer, and the annular PP cotton fine filter layer are stacked in the vertical direction, so that the diameter of the filter element device is relatively reduced, and the volume can be reduced; at the same time, when the water is filtered along the PP cotton coarse filter layer, the annular activated carbon filter layer, and the annular PP cotton fine filter layer in sequence, the raw water overflows upward, and the utilization rate of the filter material and the filtration area can be improved at this time; at the same time, the raw water does not pass through the PP cotton coarse filter layer, the annular activated carbon filter layer, and the annular PP cotton fine filter layer at the same time, which can improve the smoothness of water flow and reduce the workload of the water pump; the first check valve and the third check valve both have the function of preventing water from flowing back; at the same time, when the filter element seat is installed on the filter bottle, the filter element seat drives the clean water discharge pipe to open the second check valve, so that the clean water can be discharged from the fourth water outlet, and when the filter element seat is separated from the filter bottle, the second check valve can prevent the clean water from being discharged from the fourth water outlet;

[0033] The present invention is further configured as follows: a vertical rod check valve is arranged in the raw water inlet channel, a step corresponding to the vertical rod check valve and protruding downward is arranged at the bottom of the filter bottle, and when the third mounting groove of the filter element seat is threadedly connected to the filter bottle, the vertical rod of the vertical rod check valve presses on the step to realize opening; the third check valve is installed in the part of the clean water discharge channel outside the first mounting groove; a water-passing base is plugged and installed on the filter element seat, a water supply pipeline plugged into the raw water inlet channel and supporting the vertical rod check valve is formed on the water-passing base, the lower end of the vertical rod of the vertical rod check valve is embedded in the water supply pipeline, the spring of the vertical rod check valve contacts the end face of the water supply pipeline, a first drainage pipeline plugged into the clean water discharge channel and supporting the third check valve is formed on the water-passing base, and a second drainage pipeline plugged into the wastewater discharge channel is formed on the water-passing base.

[0034] By adopting the above scheme, the water-passing base is first installed on the filter element seat, and during the installation of the filter element seat, the vertical rod check valve is pushed up due to the presence of the step. After the filter element seat and the filter bottle are separated, the vertical rod check valve can prevent the raw water from entering the channel and being discharged.

[0035] The present invention is further configured as follows: the lower mounting ring is made of a plastic material, and a plurality of first vertical bars distributed in a circular array and pressed against the inner wall of the filter bottle are arranged on the outer wall of the lower mounting ring, and the lower end of the inner wall of the lower mounting ring is a first annular sealing portion which extends obliquely toward a direction close to the center sleeve and presses against the outer wall of the center sleeve through plastic deformation; the upper mounting ring is made of a plastic material, and a plurality of second vertical bars distributed in a circular array and pressed against the inner wall of the center sleeve are arranged on the inner wall of the upper mounting ring, and the upper end of the outer wall of the upper mounting ring is a second annular sealing portion which extends obliquely toward a direction close to the filter bottle and presses against the inner wall of the filter bottle through plastic deformation, and the lower end of the outer wall of the upper mounting ring is formed with a third annular sealing portion which protrudes toward a direction close to the filter bottle and presses against the inner wall of the filter bottle through plastic deformation.

[0037] The present invention is further configured as follows: a cover plate assembly is provided at the upper end of the pure water tank, the cover plate assembly includes a box cover covering the upper end of the pure water tank, a UV sterilization lamp arranged on the box cover, the UV sterilization lamp includes a lamp holder and a lampshade, a connecting plate is integrally provided at the middle part of the box cover, a groove is provided on the connecting plate, a connecting end embedded in the groove is integrally provided at the upper end of the lamp holder, limiting parts that abut against the upper side of the connecting end are integrally provided on the inner walls on both sides of the groove, the limiting parts on both sides are L-shaped and reversely designed, a second through hole is provided in the middle part of the groove, a connecting sleeve wrapped around the second through hole and for the lamp holder and the lampshade to be embedded is integrally provided on the lower side of the box cover, and a second limiting ring for the lower end of the lampshade to pass through is integrally provided on the peripheral side of the lower end of the connecting sleeve.

[0038] By adopting the above scheme, when the box cover is closed on the upper end of the pure water tank, the UV sterilizing lamp arranged on the box cover can sterilize the water in the pure water tank through the UV sterilizing lamp, because the UV sterilizing lamp is a lamp made by using the sterilizing effect of ultraviolet rays, so the possibility of residual bacteria in the water in the pure water tank is reduced, which is ultimately beneficial to people's health when drinking;

[0039] When the UV sterilizer lamp is damaged and needs to be replaced, the limiting parts integrally arranged on the inner walls on both sides of the groove are utilized, and the limiting parts on both sides are L-shaped and reversely designed. The limiting parts can limit the connecting end of the upper end of the lamp holder in the groove in the vertical direction, and the two limiting parts of reverse design can allow the connecting end to rotate in the horizontal plane in the groove. At this time, the connecting end is rotated toward the side away from the limiting part, so that the two sides of the connecting end are moved away from the lower side of the limiting part, and then the UV sterilizer lamp can be removed from the box cover, thereby realizing the rapid disassembly of the UV sterilizer lamp; at the same time, the new UV sterilizer lamp is embedded in the connecting sleeve and after the connecting end is rotated toward the side close to the limiting part, the two sides of the connecting end can be embedded in the lower side of the limiting part, and the UV sterilizer lamp can be quickly installed at this time; finally, it is convenient to quickly replace the UV sterilizer lamp.

[0043] By adopting the above scheme, since the water entering the pure water tank is filtered by the full-composite filter element, the minerals in the water that are beneficial to the human body will also be filtered out by the full-composite filter element, which will eventually lead to a lack of minerals in the water in the pure water tank; at this time, by utilizing the mineralized filter element installed on the lower side of the tank cover, the water in the pure water tank can be converted into mineral water rich in minerals after passing through the mineralized filter element, which can ultimately be beneficial to human health; the card hole at the upper end of the mineralized filter element is used for the elastic card buckle on the plastic card ring to be connected, which can facilitate the rapid disassembly, assembly and replacement of the mineralized filter element.

[0044] In summary, the present invention has the following beneficial effects: the main bracket is embedded with the full composite filter element through the first mounting part, the second mounting part is supported by the raw water tank, the third mounting part is embedded with the self-priming pump, the fourth mounting part is installed with the pure water tank, and the fifth mounting part is installed with the water pump and the rapid heating control module. At this time, each position on the main bracket can correspond to different components respectively, so that each component can be reasonably arranged on the main bracket, and finally each component can be easily assembled efficiently;

[0045] By installing the water pump, quick heating device, controller and power adapter on a mounting frame that is detachably connected to the main bracket, it is only necessary to transport the mounting frame assembled with the water pump, quick heating device, controller and power adapter to the test site, so as to quickly and conveniently test the heating function of the water purifier. Compared with the transportation of the entire water purifier, the weight and volume can be reduced, which is beneficial to improve the efficiency of water purifier testing. During the test, it is only necessary to connect the water pump to the external water tank for testing. BRIEF DESCRIPTION OF THE DRAWINGS
