Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] like Figure 1 and Figure 2As shown, an instant reverse osmosis water purifier comprises an outer water tank 1, a shell 2 and a main body bracket 3 arranged in the shell 2, wherein the outer water tank 1 is detachably arranged at the rear side of the shell 2;

[0055] The main support 3 includes a rear platform 31, a front platform 32 for installing a heating component 4, and an upper platform 33 for installing an electronic control component 5. The front platform 32 and the rear platform 31 are arranged at an interval, and the two and the upper platform 33 together form a receiving cavity, and a filter element component 6, a built-in water tank 7 and an RO pump 8 are arranged in the receiving cavity.

[0056] The present invention provides a feasible internal structure layout scheme for a mini water purifier. Specifically, a main body bracket 3 for dividing its internal space is provided in the shell 2. The front platform 32 and the rear platform 31 will filter the external water intake and temporarily store the water components, while the heating component 4 and the electric control component 5 of the water purifier, which involve more circuit layouts, are installed in isolation on the outside of the accommodating cavity, that is, the electric control component 5 is installed on the highest upper platform 33 in the shell 2, and the heating component 4 is installed on the front platform 32 closest to the water outlet of the water purifier, thereby effectively isolating the influence of pipeline leakage on the circuit system.

[0057] Among them, the heating component 4, the electronic control component 5, the filter element component 6, the built-in water tank 7, the RO pump 8 and the waterway plate component 18 are all conventional technical features in the reverse osmosis water purifier. The RO pump 8 provides power for sending water from the external water tank 1 into the filter element component 6. The water is processed by the filter element component 6 to obtain clean water and is sent to the built-in water tank 7. When the user needs hot water, the water in the built-in water tank 7 is sent out after passing through the heating component 4, and all the working contents of the entire reverse osmosis water purifier are completed by sending instructions to related components through the electronic control component 5.

[0058] Preferably, a partition is provided to separate the accommodating cavity in a front-to-back order to form a front cavity 301 and a rear cavity 302, the filter element assembly 6 is detachably arranged in the rear cavity 302, the built-in water tank 7 and the RO pump 8 are arranged in the front cavity 301. In this embodiment, the accommodating cavity is divided into the front cavity 301 and the rear cavity 302 by a partition, and the built-in water tank 7, the RO pump 8 and the filter element assembly 6 are further separated and arranged in two relatively independent cavities, which provides a good space for the quick replacement of the filter element assembly 6.

[0059] Preferably, it further comprises a waterway plate assembly 18, wherein the waterway plate assembly 18 comprises a plate body and a first water passage and a second water passage arranged in the plate body;

[0060] The first water passage serves as a water inlet connection hub, and is respectively connected to the filter element assembly 6, the outer water tank 1 and the built-in water tank 7, and the RO pump 8 is provided in the connection pipeline between the first water passage and the outer water tank 1;

[0061] The second water passage serves as a water outlet connection hub, and is respectively connected to the wastewater outlet of the filter element assembly 6 and the outer water tank 1 .

[0062] In this embodiment, a waterway plate assembly 18 is provided as a pivotal component for connecting and communicating the various waterways inside the water purifier, which improves space utilization and compacts the internal structure layout of the water purifier; and the plate body with a certain strength can well support and meet the repeated disassembly and assembly between the filter element assembly 6 and its first water passage. When in use, the RO pump 8 provides power to allow the water in the outer water tank 1 to enter the first water passage, and then the purified water obtained by the filter element assembly 6 enters the inner water tank 7. The filter element assembly 6 is generally composed of multiple filter elements connected in series, and the water entering from the outer water tank 1 passes through these multiple filter elements in turn and is sent to the inner water tank 7;

[0063] The waste water generated by the operation of the filter element assembly 6 flows back to the external water tank 1 through the second water passage. A waste water pipe can be connected between the second water passage and the external water tank 1. The waste water pipe is directly or indirectly connected to the external water tank 1, and a one-way stop valve is provided on the connection path between the waste water pipe and the external water tank 1. The filtered waste water is directly sent back to the external water tank 1 for repeated filtration and use, thereby establishing a closed-loop treatment and use method for the filtered waste water, which not only simplifies the internal structure of the water purifier, but also improves the utilization rate of water resources, and is environmentally friendly and energy-saving.

[0064] Furthermore, the outer water tank 1 is provided with a water inlet channel, and the water inlet channel is provided with a mother valve assembly 11 of the one-way flow-stop valve. When the mother valve assembly 11 acts alone, the water inlet channel is in a blocked state;

[0065] The housing 2 is provided with a water inlet guide channel, and the water inlet guide channel is provided with a guide component 12 of the one-way stop valve; when the outer water tank is assembled to the housing 2, the water inlet channel corresponds to the water inlet guide channel, and the guide component 12 acts on the mother valve component 11 to make the water inlet channel conduct and connect with the water inlet guide channel;

[0066] The waste water pipe is directly or indirectly connected to the water inlet diversion channel.

[0067] Preferably, the RO pump 8 is arranged on the side of the built-in water tank 7, and the waterway plate assembly 18 is arranged above the built-in water tank 7, which has a compact structure and is easy to install.

[0068] Furthermore, a wastewater flushing valve 9 is provided on the pipeline connecting the wastewater outlet of the filter element assembly 6 and the external water tank 1, and the wastewater flushing valve 9 is arranged above the built-in water tank 7; the wastewater flushing valve 9 is used to flush the filter element assembly 6 to extend the service life of the filter element assembly 6. The wastewater flushing valve 9 generally includes at least two states: allowing a large flow to pass through and allowing a small flow to pass through. When it is adjusted to allow a small flow to pass through, the wastewater of the filter element assembly 6 passes normally to enter the external water tank 1 for recovery. When it is adjusted to allow a large flow to pass through, the filter element is flushed due to the excessive impact of the water flow, and the water after flushing will also directly enter the external water tank 1 through the wastewater pipe, which is convenient to use.

[0069] Preferably, if Figure 3 and Figure 4 As shown, the air outlet of the built-in water tank 7 is connected to an exhaust / drain pipe 71;

[0070] One end of the exhaust / drain pipe 71 is connected to the top or upper side of the built-in water tank 7, and the other end is connected to the external connection hole 21 provided on the shell 2, so as to maintain the air pressure balance between the built-in water tank 7 and the outside, and to collect or discharge the purified water overflowing or spilled from the built-in water tank 7 to the outside of the water purifier when the built-in water tank 7 is tilted or tilted with the water purifier.

[0071] There are many live components inside the water purifier. The air outlet of the built-in water tank 7 in the present technical solution is connected to the exhaust / drain pipe 71. Its main function is to prevent the water in the built-in water tank 7 from overflowing and spilling along the exhaust hole when the water purifier tilts or falls over during movement, and spread to the inside of the product, thereby affecting or even destroying the normal use of the live components, thereby fundamentally ensuring the safe use of the water purifier.

[0072] Specifically, in the present embodiment, an exhaust / drain pipe 71 is provided and connected to the top or upper side of the built-in water tank 7. On the one hand, it is used for exhausting the built-in water tank 7 to maintain the internal air pressure of the built-in water tank 7 in balance with the external air pressure, thereby ensuring that the purified water can flow smoothly into the built-in water tank 7. On the other hand, it also provides space and a path for the water in the built-in water tank 7 to overflow when the built-in water tank 7 tilts or falls over along with the water purifier.

[0073] One end of the exhaust / drain pipe 71 is connected to the top or upper side of the built-in water tank 7, and the other end thereof can be connected to the external connection hole 21 provided on the upper part of the shell of the water purifier. This may cause that the amount of water overflowing from the built-in water tank 7 is not much, and the pipe body of the exhaust / drain pipe 71 is only used to temporarily store the overflowed water. This is the first embodiment;

[0074] Another embodiment of the connection method between the exhaust / drain pipe 71 and the water purifier housing is that the water purifier sets the external hole 21 at the lower part of its housing. The best position is to set the external hole 21 on the bottom wall of the housing, and then connect the other end of the exhaust / drain pipe 71 to the external hole 21. In this way, the water overflowing from the built-in water tank 7 will most likely be directly discharged along the pipe body of the exhaust / drain pipe 71 to the outside of the water purifier, thereby avoiding water spillage that affects the normal use of components. The above two connection methods should fall within the protection scope of the present invention.

[0075] Preferably, the external connection hole 21 is arranged on the bottom end surface of the shell 2, so that the water overflowing from the built-in water tank 7 is directly discharged from the bottom of the water purifier, completely eliminating the possibility of the overflowing water affecting its internal components, and also facilitating the collection of water discharged from the water purifier.

[0076] Preferably, the heating component 4 includes a heating body 41 and a heating water pump 42. The heating water pump 42 is connected to the built-in water tank 7 and the heating body 41 respectively through pipelines to provide power for the purified water in the built-in water tank 7 to enter the heating body 41. The water heated by the heating body 41 flows out from the water outlet of the water purifier through the pipeline.

[0077] In this embodiment, the RO pump 8 pumps the water in the external water tank 1 into the filter element assembly 6 for filtration. The water filtered by the filter element assembly 6 enters the built-in water tank 7 through the pipeline. When the user needs to take hot water from the water purifier, the heating pump 42 draws the clean water in the built-in water tank 7 into the heating element 41 for heating, and then flows out from the water outlet of the water purifier.

[0078] Preferably, if Figure 7 As shown, when the amount of water in the outer water tank 1 can no longer support the operation of the water purifier, the outer water tank 1 needs to be removed from the shell 2 for a preset period of time before the outer water tank 1 can be assembled to the shell 2 to allow the water purifier to start working again. This embodiment relates to a control method for a water purifier, which has a mandatory requirement that when the amount of water in the outer water tank 1 can no longer support continued operation, the outer water tank 1 must be removed from the shell 2 for a preset period of time, such as 3 seconds later, and then the outer water tank 1 can be reassembled to the shell 2 before the control system of the water purifier can be restarted to start working. It is expected that the user is forced to remove the outer water tank 1, pour out the remaining water therein, and then add new water before reusing it, so as to develop good hygiene habits.

[0079] Preferably, if Figure 5 , Figure 6 and Figure 7As shown, a micro switch 10 is installed at the assembly position of the outer water tank 1 and the shell 2, and the micro switch 10 is electrically connected to the control module of the water purifier to transmit a signal of whether the outer water tank 1 and the shell 2 are installed in place to the control module.

[0080] When the outer water tank 1 needs to move the shell 2 due to water addition or other reasons, and then moves it back to be installed on the shell 2, it is necessary to ensure that the water inlet, water outlet and other water channels of the joint are accurately installed in place and in a conductive state, so that the system can continue to operate safely. In the prior art, an infrared sensing element is basically set at the joint to detect whether it is installed in place. Only when it is detected that it is installed in place will the control module send a signal that it can continue to move; practice has proved that the detection components related to the infrared sensing principle at this stage often have the problem of low accuracy. The two assembled parts do not need to be completely and accurately assembled in place. As long as a certain part of the component is sensed by infrared, a signal feedback will be sent, which brings great safety problems to the use of the water purifier. For example, a signal of installation is sent when it is not completely in place, and the equipment machine enters a state of continuing to work. When the water inlets of the outer water tank 1 and the shell 2 are not aligned, water will be spilled all over the floor and even affect the normal use of electronic components; the wastewater outlet of the external water tank and the shell 2 has not been connected, and the wastewater pump starts to work according to the system instruction, which is easy to cause the pressure of the wastewater pipe to increase and cause the pipeline to burst, etc.

[0081] In this embodiment, a micro switch 10 is provided to detect whether the outer water tank 1 is accurately and completely installed to the housing 2, so as to avoid the problem that the system is not yet ready for continued working due to the inaccurate and complete installation, and the internal water pressure increases. For example, if the outer water tank 1 is not installed in place, the spring of the one-way check valve at the waste water outlet of the outer water tank 1 cannot be opened after the machine is operated, and the waste water cannot flow back to the outer water tank 1, causing the waste water pipe pressure to increase, resulting in bursting of the pipeline. The working principle of the micro switch 10 determines that its spring piece must be pressed to change the position in physical distance before it can send out the relevant induction signal, and use it to detect whether the outer water tank 1 is accurately installed. The pressing state of the spring piece when the outer water tank 1 is accurately installed to the housing 2 can be used as the standard for sending the detection signal to the control module. Only when the state of the spring piece during installation reaches the standard, will the control module send the signal of installation in place, otherwise it will not send. This physical space state change and the control of the physical position when the outer water tank 1 and the housing 2 are installed form a phase mapping relationship, with high detection accuracy, ensuring the safe operation of the water purifier.

[0082] When in use, when the outer water tank 1 is accurately and completely installed into the shell 2, the micro switch 10 is triggered to transmit a signal, and the control module can work normally when it detects that the micro switch 10 is closed; the installation can be carried out 3 seconds after the outer water tank 1 is lifted to change the water. At this time, if the water tank is not installed in place, the control module and the entire internal system will not work. It is easy to use and has high accuracy.

[0083] Preferably, the outer water tank 1 is provided with a water outlet channel, and the shell 2 is provided with a water outlet diversion channel. When the outer water tank 1 is assembled to the shell 2, the water outlet channel is connected to the water outlet diversion channel, and a one-way stop valve is provided on the communication path between the two.

[0084] The water outlet diversion channel is directly or indirectly connected to the water inlet of the filter element assembly 6 through a pipeline, and has a simple structure and is easy to install.

[0085] There are multiple implementation structures for the specific structure of the one-way flow-stop valve, which generally includes a mother valve assembly 11 and a flow guide assembly 12, and the mother valve assembly 11 is installed in the outer water tank 1, and the flow guide assembly 12 is installed in the shell 2, which is used to control the unblocking state of the one-way water outlet path from the outer water tank 1 to the shell 2, or the one-way water inlet path from the shell 2 to the outer water tank 1 (mainly wastewater entering the outer water tank 1);

[0086] The following is an example of using a one-way check valve to control the unblocked state of the water outlet path from the outer water tank 1 to the shell 2. The control principle of the unblocked state of the water inlet path from the shell 2 to the outer water tank 1 is the same and will not be repeated.

[0087] In this embodiment, Figure 8 , Fig. 9 and Fig.10 As shown, the flow guide assembly 12 includes a flow guide seat 121, a first flow guide column 122 and a first elastic member 123;

[0088] The guide seat 121 is provided with a guide channel 121a, and the first guide column 122 is arranged in the guide channel 121a through the first elastic member 123 so as to be linearly reciprocatingly movable, so that when the outer water tank 1 is assembled to the housing 2, it can act on the mother valve assembly 11 to change the mother valve assembly 11 from a blocked state to a conducting state.

[0089] The guide channel 121a at least includes a section of an assembly channel 121aa and a section of an inclined channel 121ab. The first guide column 122 is adaptively assembled in the assembly channel 121aa, and a water gap for water to flow through is formed between its outer wall and the inner wall of the assembly channel 121aa. The inclined channel 121ab is connected to the lower end of the assembly channel 121aa, and its inner diameter gradually increases in the direction away from the assembly channel 121aa.

[0090] The outer wall of the first guide column 122 is provided with a guide column sealing ring 13. When the first guide column 122 makes a linear reciprocating motion, the guide column sealing ring 13 uses the inner wall surface of the inclined channel 121ab to achieve blocking and conduction control of the water gap.

[0091] The technical solution of the present invention is used for connecting the outer water tank 1 and the shell 2 of the water purifier to solve the problem that the existing connection components are prone to friction and aging due to long-term plugging and unplugging, and then water leakage occurs.

[0092] When the present technical solution is in use, the mother valve assembly 11 is precisely assembled to the shell 2, the first guide column 122 is pressed downward and acts on the mother valve assembly 11 to put it in a conducting state, and at the same time, the guide channel 121a of the guide assembly 12 is also in a conducting state, and the two are connected to form a path for water to flow from the outer water tank 1 into the shell 2; when the outer water tank 1 is not assembled to the shell 2, the mother valve assembly 11 is in a blocked state to prevent water in the outer water tank 1 from leaking out, and the first guide column 122 is reset upward to re-block the guide channel 121a to prevent return water from overflowing from the guide channel 121a, which is convenient for use.

[0093] Specifically, when the outer water tank 1 is not assembled to the shell 2, the first guide column 122 of the guide assembly 12 is not pressed downward, and the guide column sealing ring 13 is tightly against the inner wall surface of the small inner diameter end of the inclined channel 121ab, blocking the path of the water gap channel and the guide channel 121a below it; when the outer water tank 1 is assembled to the shell 2, the first guide column 122 is pressed downward, directly causing the first elastic member 123 to be in a compressed state, and the guide column sealing ring 13 moves downward with the first guide column 122 in the direction of the gradually increasing inner diameter of the inclined channel 121ab, and then gradually breaks away from the inner wall surface of the inclined channel 121ab, thereby removing the obstruction to the water gap channel. The outer water tank 1 is disconnected, so that the water gap is connected with the guide channel 121a below it; when the outer water tank 1 leaves the shell 2, under the action of the restoring force of the first elastic member 123, the first guide column 122 is reset upward, and the guide column sealing ring 13 moves upward to re-block the water gap. In this embodiment, the inclined surface is directly used to form a channel for blocking, and the sealing ring and a certain elastic extrusion force are used to realize the control of the transition between the blocking and conduction states of the guide channel 121a. At the same time, it also meets the assembly requirements of the linear reciprocating motion of the first guide column 122. The structure is simple and easy to implement, and maintenance is convenient (the guide column sealing ring 13 can be replaced after wear), and the overall service life of the product is long.

[0094] Preferably, the first flow guide column 122 is composed of a first column portion 122a, an inner groove portion 122b, a second column portion 122c and a rod portion 122d from top to bottom, and the outer diameter of the first column portion 122a is adapted to the inner diameter of the assembly channel 121aa; the flow guide column sealing ring 13 is sleeved on the inner groove portion 122b, and the outer diameter of the first column portion 122a is larger than the outer diameter of the inner groove portion 122b, but smaller than the outer diameter of the second column portion 122c;

[0095] The outer diameter of the rod body portion 122d is smaller than the outer diameter of the second column portion 122c. The upper end of the first elastic member 123 abuts against the end surface of the second column portion 122c, and the lower end thereof abuts against the assembly channel 121aa or a component installed and fixed in cooperation with the assembly channel 121aa.

[0096] In this embodiment, an inner groove portion 122b is designed on the first guide column 122 for installing the guide column sealing ring 13 to ensure the stability of its installation; on the other hand, the outer diameter of the second column portion 122c is larger than the outer diameter of the first column portion 122a, and is also larger than the inner diameter of the assembly channel 121aa to prevent the first guide column 122 from escaping from the upper end of the guide channel 121a. The structure is simple and the installation is convenient.

[0097] Preferably, the assembly channel 121aa is installed on the diversion valve base 14, and the diversion valve base 14 is provided with a discharge channel 141 communicating with the diversion channel 121a;

[0098] The diverter valve base 14 is further provided with a guide groove 142 for the lower end of the rod body portion 122 d to be reciprocally inserted, and the lower end of the first elastic member 123 abuts against the upper end surface of the guide groove 142 .

[0099] In this embodiment, the guide groove 142 defines the path of the linear motion of the rod body 122 d , thereby improving the accuracy of its action on the mother valve assembly 11 .

[0100] As for the structure of the mother valve assembly 11, a preferred implementation method is to include a mother valve body 111, a second elastic member 112 and a second guide column 113, wherein the mother valve body 111 is disposed in the outer water tank 1 and is provided with a water outlet channel 111a communicating with the outer water tank 1;

[0101] The second guide column 113 is disposed in the water outlet channel 111a so as to be linearly reciprocatingly movable through the second elastic member 112, so as to control the conduction and blocking of the water outlet channel 111a;

[0102] When the mother valve assembly 11 and the flow guide assembly 12 are assembled and installed, the water outlet channel 111a is connected with the flow guide channel 121a, and the second flow guide column 113 is opposite to the first flow guide column 122, which has a simple structure and is easy to use.

[0103] In this embodiment, the outer water tank 1 is precisely assembled to the housing 2, and the first guide column 122 acts on the second guide column 113 to make it move upward, thereby leaving the blocked position, the water outlet channel 111a is opened, and the second elastic member 112 is in a compressed state; when the outer water tank 1 is removed from the housing 2, the upward force of the first guide column 122 on the second guide column 113 disappears, and the second guide column 113 moves downward under the restoring force of the second elastic member 112, returns to the blocked position, and the water outlet channel 111a is blocked. There are many structures of the mother valve assembly 11 that can realize the above functions in the prior art, and the preferred implementation forms are as follows:

[0104] The upper end of the water outlet channel 111a is provided with a water outlet hole, and the second guide column 113 passes through the water outlet hole upward, and a water outlet gap is formed between the hole wall of the water outlet hole and the outer side wall of the second guide column 113;

[0105] The outer wall of the second guide column 113 passing through the water outlet hole is provided with a water tank guide column sealing ring 15. When the water tank guide column sealing ring 15 is attached to the upper end surface of the water outlet channel 111a, it blocks the water outlet gap; when the water tank guide column sealing ring 15 moves upward with the second guide column 113 and leaves the upper end surface of the water outlet channel 111a, the water outlet gap is blocked, the structure is simple, and the installation is convenient.

[0106] For the assembly structure of the mother valve assembly 11 and the guide assembly 12, the preferred implementation form is that the inner diameter of the water outlet channel 111a is equivalent to the outer diameter of the guide channel 121a, so that the guide channel 121a can be adaptably inserted into the water outlet channel 111a, thereby preventing the water in the outer water tank 1 from leaking to the outside during the process of flowing into the guide channel 121a along the water outlet channel 111a, and the anti-leakage effect is obvious.

[0107] Preferably, a shell inner sealing ring 161 is provided between the inner wall surface of the guide channel 121a and the outer wall surface of the water outlet channel 111a to block the water leakage channel that may be formed between the outer wall surface of the guide channel 121a and the inner wall surface of the water outlet channel 111a, thereby enhancing the above-mentioned anti-leakage effect.

[0108] Furthermore, a shell outer sealing ring 162 is provided simultaneously or separately, and is sleeved on the outer wall surface of the diversion channel 121a. The shell outer sealing ring 162 is provided with a sealing ring wall 162a extending vertically upward. When the mother valve assembly 11 and the diversion assembly 12 are assembled and installed, the wall surface of the water outlet channel 111a is limited between the sealing ring wall 162a and the outer wall surface of the diversion channel 121a, and the leakage channel that may be formed on the outer wall surface of the water outlet channel 111a is blocked, thereby strengthening the above-mentioned anti-leakage effect. The assembly structure of the outer wall surface of the guide channel 121a can be directly and tightly attached, which has the best anti-leakage effect; or a sealing protrusion 162b protruding toward one side of the guide channel 121a is provided on the inner wall surface of the sealing ring wall 162a, and the sealing protrusion 162b is used to block the leakage channel that may be formed on the outer wall surface of the water outlet channel 111a. This can not only achieve the effect of anti-leakage, but also make it more convenient to adaptably insert the guide channel 121a into the water outlet channel 111a (reduced contact area and reduced friction), and there are multiple flexible ways.

[0109] Preferably, the guide seat 121 also includes a guide seat cover 121b for installation and positioning, the guide seat cover 121b is connected to the guide channel 121a to form a T-shaped structural member, the outer sealing ring 162 of the shell is supported by the upper end surface of the guide seat cover 121b, and the upper end of the sealing ring wall 162a is limited by the shell 2, with a simple structure and easy installation.

[0110] Preferably, the diversion seat 121 is installed on the diversion valve base 14 through the diversion seat cover 121b, and the diversion valve base 14 is provided with a discharge channel 141 communicating with the diversion channel 121a;
