Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, specifically providing a drinking water equipment and its control method. Background Technology

[0002] As people's living standards continue to improve, water dispensers, water purifiers, and other drinking water equipment have become common household appliances. These devices are equipped with instant heating units that rapidly heat water to boiling before discharging it. However, the process of boiling the water generates a large amount of steam, which is then ejected from the outlet. The unpredictable direction of this high-temperature steam can easily scald users. Typically, water dispensers are designed so that the water is heated to near 100°C (e.g., 97°C) before being discharged. This design prevents the water from reaching a boiling point, avoiding the risk of scalding users from the large amount of high-temperature steam ejected from the outlet.

[0003] However, the boiling point of water varies at different altitudes, with higher altitudes having lower boiling points. When drinking water equipment is used at higher altitudes, the boiling point of water is below 97°C. The water flowing through the instant heating device is heated to its boiling point, generating a large amount of high-temperature steam, which is then ejected from the outlet along with the water flow.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, the problem that existing drinking water equipment tends to spray out a large amount of high-temperature water vapor from the outlet when used in high-altitude areas.

[0006] In a first aspect, the present invention provides a control method for a drinking water device, the drinking water device including an instant heating device, the inlet and outlet of the instant heating device being respectively connected to an inlet pipe and an outlet pipe, the control method comprising: comparing a set boiling point with a set heating temperature value; determining a target heating temperature value based on the comparison result; obtaining an inlet water temperature value; heating water flowing through the instant heating device according to the target heating temperature value; obtaining an outlet water temperature value; comparing the outlet water temperature value with the target heating temperature value; selectively updating the set boiling point to the outlet water temperature value based on the comparison result, and then returning to the step of "comparing the set boiling point with the set heating temperature value"; wherein the target heating temperature value is not greater than either the set boiling point or the set heating temperature value.

[0007] In the preferred embodiment of the above control method, the step of "selectively updating the set boiling point to the outlet water temperature value according to the comparison result" specifically includes: if the outlet water temperature value is less than the target heating temperature value, then the set boiling point is updated to the outlet water temperature value.

[0008] In the preferred embodiment of the above control method, the step of "selectively updating the set boiling point to the outlet water temperature value according to the comparison result" specifically includes: if the outlet water temperature value is less than the target heating temperature value, then increasing the water flow rate through the instant heating device or decreasing the heating power of the instant heating device and detecting whether the outlet water temperature changes; selectively updating the set boiling point to the outlet water temperature value according to the detection result.

[0009] In the preferred embodiment of the above control method, the step of "selectively updating the set boiling point to the outlet water temperature value according to the detection result" specifically includes: if the outlet water temperature remains unchanged, then the set boiling point is updated to the outlet water temperature value.

[0010] In the preferred embodiment of the above control method, the step of "selectively updating the set boiling point to the outlet water temperature value according to the detection result" further includes: if the outlet water temperature decreases, a fault prompt message is issued.

[0011] In the preferred embodiment of the above control method, the step of "determining the target heating temperature value based on the comparison result" specifically includes: determining the smaller value between the set boiling point and the set heating temperature value as the target heating temperature value.

[0012] In the preferred embodiment of the above control method, the step of "determining the target heating temperature value based on the comparison result" specifically includes: if the set heating temperature value is less than the set boiling point, then the set heating temperature value is determined as the target heating temperature value; if the set heating temperature value is not less than the set boiling point, then the result of subtracting a preset value from the set heating temperature value is determined as the target heating temperature value.

[0013] In the preferred embodiment of the above control method, the step of "comparing the set boiling point with the set heating temperature value" specifically includes: when running the boiling water mode for the first time after each power-on, comparing the set boiling point with the set heating temperature value.

[0014] In a preferred embodiment of the above control method, the drinking water device further includes a diversion pipe and a water storage device. The two ends of the diversion pipe are respectively connected to the outlet of the instant heating device and the water storage device. The drinking water device is configured to selectively connect the outlet of the instant heating device to either the diversion pipe or the outlet pipe. The control method further includes: if the outlet water temperature is less than the target heating temperature, then connecting the outlet of the instant heating device to the diversion pipe; otherwise, connecting the outlet of the instant heating device to the outlet pipe.

[0015] When using the above technical solution, the following steps are taken: compare the set boiling point with the set heating temperature value; determine the target heating temperature value based on the comparison result; obtain the inlet water temperature value; heat the water flowing through the instant heating device according to the target heating temperature value; obtain the outlet water temperature value; compare the outlet water temperature value with the target heating temperature value; selectively update the set boiling point to the outlet water temperature value based on the comparison result, and then return to the step of "comparing the set boiling point with the set heating temperature value"; wherein, the target heating temperature value is not greater than either the set boiling point or the set heating temperature value.

[0016] If the actual boiling point is lower than the target heating temperature, the outlet water temperature is usually equal to the actual boiling point. The heat generated by the instant heating device is sufficient to heat the flowing water to its boiling point, while the excess heat causes some water to evaporate rapidly, producing a large amount of high-temperature steam. Through the above control method, the target heating temperature, determined based on the set boiling point and the set heating temperature, is not greater than either the set boiling point or the set heating temperature. When heating water flowing through the instant heating device according to the target heating temperature, by comparing the outlet water temperature with the target heating temperature, it can be determined whether the actual boiling point is lower than the target heating temperature. Based on the determination result, the set boiling point is selectively updated, and heating is selectively performed according to the new target heating temperature. This reduces the occurrence of situations where a large amount of high-temperature steam is ejected from the outlet pipe when the actual boiling point is lower than the target heating temperature, improving the safety of users when collecting boiling water and optimizing the user experience.

[0017] Preferably, the step of "selectively updating the set boiling point to the outlet water temperature value according to the comparison result" specifically includes: if the outlet water temperature value is less than the target heating temperature value, increasing the water flow rate through the instant heating device or decreasing the heating power of the instant heating device and detecting whether the outlet water temperature changes, and selectively updating the set boiling point to the outlet water temperature value according to the detection result.

[0018] In instant water heaters comprising multiple parallel heating modules, if some modules malfunction and the actual boiling point is higher than the target heating temperature, the water heater will heat the water flowing through it according to the target temperature, resulting in an outlet water temperature lower than the target temperature. If the outlet water temperature is lower than the target temperature, the water flow rate through the instant water heater will be increased or the heating power will be reduced, and the outlet water temperature will be monitored. Based on the monitoring results, the set boiling point will be selectively updated to the outlet water temperature. This allows for a more accurate determination of whether the lower outlet water temperature is due to the actual boiling point being lower than the target heating temperature, enabling more precise boiling point updates and effectively reducing the occurrence of large amounts of high-temperature steam ejected from the outlet pipe.

[0019] Preferably, the step of "determining the target heating temperature value based on the comparison result" specifically includes: if the set heating temperature value is less than the set boiling point, then the set heating temperature value is determined as the target heating temperature value; if the set heating temperature value is not less than the set boiling point, then the result of subtracting the preset value from the set heating temperature value is determined as the target heating temperature value.

[0020] This design prevents water vapor from spraying out of the outlet pipe when the water is heated to its boiling point.

[0021] Preferably, the drinking water equipment further includes a diversion pipe and a water storage device, with the two ends of the diversion pipe connected to the outlet of the instant heating device and the water storage device, respectively. The drinking water equipment is configured to selectively connect the outlet of the instant heating device to either the diversion pipe or the outlet water pipe. The control method further includes: if the outlet water temperature is less than the target heating temperature, then connecting the outlet of the instant heating device to the diversion pipe; otherwise, connecting the outlet of the instant heating device to the outlet water pipe.

[0022] With this setting, when the actual boiling point is lower than the target heating temperature, it can prevent the outlet of the water pipe from spraying out high-temperature steam in the short period before the boiling point is updated, thus effectively preventing the outlet of the water pipe from spraying out high-temperature steam.

[0023] In a second aspect, the present invention provides a drinking water device comprising: a memory; a processor; and a computer program, the computer program being stored in the memory and configured to be executed by the processor to implement the control method of the drinking water device as described in any of the above technical solutions.

[0024] It should be noted that the drinking water equipment has all the technical effects of the control method of the drinking water equipment described in any of the above technical solutions, and will not be repeated here. Attached Figure Description

[0030] Figure 5 This is a detailed step diagram of the control method for the fourth type of drinking water equipment of the present invention. Detailed Implementation

[0031] First, those skilled in the art should understand that the embodiments described below are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that in the description of this invention, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; and it can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] In light of the problem mentioned in the background art that existing drinking water equipment tends to spray out a large amount of high-temperature water vapor from the outlet when used in high-altitude areas, this invention provides a control method for drinking water equipment that can reduce the occurrence of a large amount of high-temperature water vapor spraying out of the outlet of the water pipe when the actual boiling point is lower than the target heating temperature value, thereby improving the safety of users when filling boiling water and optimizing the user experience.

[0035] The following is combined Figures 1 to 5 The present invention will now be described. Among other things, Figure 1 This is a diagram showing the main steps of the control method for the drinking water equipment of the present invention; Figure 2 This is a detailed step diagram of the control method for the first drinking water device of the present invention; Figure 3 This is a detailed step diagram of the control method for the second type of drinking water device of the present invention; Figure 4 This is a detailed step diagram of the control method for the third type of drinking water equipment of the present invention;

[0036] Figure 5 This is a detailed step diagram of the control method for the fourth type of drinking water equipment of the present invention.

[0037] The drinking water device of the present invention includes an instant heating device, wherein the inlet and outlet of the instant heating device are respectively connected to an inlet pipe and an outlet pipe. Figure 1 As shown, the control method of the drinking water device of the present invention mainly includes:

[0038] Step S100: Compare the set boiling point with the set heating temperature value.

[0039] It should be noted that the controller of the water dispenser stores a set boiling point (such as the default boiling point of 100℃ after leaving the factory). The set heating temperature value can be the heating temperature value of the boiling water mode stored in the controller (such as 100℃, 98℃, 95℃ or other values), or it can be the heating temperature value selected by the user from multiple heating temperature values ​​stored in the controller, or the heating temperature value directly entered by the user.

[0040] Step S200: Determine the target heating temperature value based on the comparison results.

[0041] The target heating temperature value shall not exceed the set boiling point and the set heating temperature value.

[0042] Step S300: Obtain the inlet water temperature value.

[0043] Step S400: Heat the water flowing through the instant heating device according to the target heating temperature value.

[0044] Specifically, the outlet water temperature can be adjusted by regulating the water flow rate or the heating power of the instant heating device. For drinking water equipment that adjusts the outlet water temperature by regulating the water flow rate, the target water flow rate can be calculated based on the target heating temperature, the inlet water temperature, and the heating power of the instant heating device. The inlet water pipe is then controlled to supply water to the instant heating device according to the target flow rate, and the instant heating device heats the flowing water. For drinking water equipment that adjusts the outlet water temperature by regulating the heating power of the instant heating device, the target heating power can be calculated based on the target heating temperature, the inlet water temperature, and the water flow rate. The instant heating device is then controlled to heat the flowing water according to the target heating power.

[0045] Step S500: Obtain the outlet water temperature value.

[0046] Step S600: Compare the outlet water temperature value with the target heating temperature value.

[0047] Step S700: Selectively update the set boiling point to the outlet water temperature value based on the comparison result, and then return to step S100.

[0048] The target heating temperature, determined based on the set boiling point and set heating temperature, must not exceed these values. When heating water flowing through the instant heating device according to the target heating temperature, the actual boiling point can be determined by comparing the outlet water temperature with the target heating temperature. Based on this determination, the set boiling point is selectively updated, and heating is then selectively performed according to the new target heating temperature. This reduces the occurrence of large amounts of high-temperature steam spraying from the outlet pipe when the actual boiling point is lower than the target heating temperature, improving user safety when filling hot water and optimizing the user experience.

[0049] In a first specific embodiment of the present invention, the drinking water equipment includes an instant heating device. The inlet and outlet of the instant heating device are respectively connected to an inlet pipe and an outlet pipe. A first temperature sensor and a second temperature sensor are respectively installed on the inlet pipe and the outlet pipe. An adjustable flow rate water pump is also installed on the inlet pipe. Figure 2 As shown, the control method for the drinking water equipment includes the following steps:

[0050] Step S100: Compare the set boiling point with the set heating temperature value.

[0051] Step S210: Determine the smaller value between the set boiling point and the set heating temperature value as the target heating temperature value.

[0052] Step S300: Obtain the inlet water temperature value.

[0053] Step S400: Heat the water flowing through the instant heating device according to the target heating temperature value.

[0054] Specifically, the target water flow rate can be calculated based on the target heating temperature, the inlet water temperature, and the heating power of the instant heating device. The water pump is then controlled to operate at a speed corresponding to the target water flow rate, and water is supplied to the instant heating device according to the target water flow rate. The instant heating device then heats the water flowing through it.

[0055] Step S500: Obtain the outlet water temperature value.

[0056] Step S600: Determine whether the outlet water temperature is less than the target heating temperature. If so, proceed to step S710; otherwise, return to step S100.

[0057] Step S710: Update the set boiling point to the outlet water temperature value, and then return to step S100.

[0058] This setup directly prevents a large amount of water vapor from spraying out of the water outlet when the actual boiling point is lower than the set heating temperature but higher than the set boiling point. It also determines whether the set boiling point needs to be updated based on the difference between the water outlet temperature and the target heating temperature when the actual boiling point is lower than both the set boiling point and the set heating temperature. After updating the set boiling point, the target heating temperature is determined based on the updated set boiling point and the set heating temperature. The water flowing through the instant heating device is then heated according to the target heating temperature, thus preventing a large amount of water vapor from spraying out of the water outlet.

[0059] It should be noted that in the above embodiments, if the outlet water temperature is not less than the target heating temperature, the process may not need to return to step S100. Furthermore, adjusting the flow rate of water to the instant heating device via a water pump is only one specific setting method. In practical applications, adjustments can be made. For example, an adjustable flow valve can be installed on the inlet or outlet pipe, and the flow rate of water passing through the instant heating device can be adjusted by regulating the opening of the flow regulating valve.

[0060] In a second specific embodiment of the present invention, the drinking water equipment includes an instant heating device. The inlet and outlet of the instant heating device are respectively connected to an inlet pipe and an outlet pipe. A first temperature sensor and a second temperature sensor are respectively installed on the inlet pipe and the outlet pipe. An adjustable water pump is also installed on the inlet pipe. Figure 3 As shown, the control method for the drinking water equipment includes the following steps:

[0061] Step S100: Compare the set boiling point with the set heating temperature value.

[0062] Step S210: Determine the smaller value between the set boiling point and the set heating temperature value as the target heating temperature value.

[0063] Step S300: Obtain the inlet water temperature value.

[0064] Step S400: Heat the water flowing through the instant heating device according to the target heating temperature value.

[0065] Step S500: Obtain the outlet water temperature value.

[0066] Step S600: Determine whether the outlet water temperature is less than the target heating temperature. If so, proceed to step S721; otherwise, return to step S100.

[0067] Step S721: Increase the water flow rate of the instantaneous heating device and detect whether the outlet water temperature changes. After step S721, proceed to steps S722 and S723.

[0068] Step S722: If the outlet water temperature remains unchanged, update the set boiling point to the outlet water temperature value, and then return to step S100.

[0069] Step S723: If the outlet water temperature decreases, a fault warning message will be issued.

[0070] In the case of an instant heating device that includes multiple heating modules connected in parallel, if some of the heating modules malfunction and the actual boiling point is higher than the target heating temperature, the water dispenser will heat the water flowing through the instant heating device according to the target heating temperature, and the outlet water temperature will be lower than the target heating temperature. If the outlet water temperature is lower than the target heating temperature, the flow rate of water through the instant heating device is increased, and the outlet water temperature is checked for changes. If the outlet water temperature remains unchanged, the set boiling point is updated to the outlet water temperature. If the outlet water temperature decreases, a fault warning message is issued. This allows for a more accurate determination of whether the actual boiling point is lower than the target heating temperature, thus enabling precise updating of the set boiling point. This effectively reduces the occurrence of large amounts of high-temperature steam ejected from the outlet pipe. Furthermore, it alerts the user when the instant heating device malfunctions, facilitating timely repairs. It also avoids situations where, in such cases, the set boiling point is updated to the outlet water temperature, the target heating temperature is determined based on the new set boiling point and the set heating temperature, and the water flowing through the instant heating device is heated according to the target heating temperature, resulting in the supplied hot water failing to meet the user's set temperature requirements due to the instant heating device malfunction.

[0071] In a third specific embodiment of the present invention, the drinking water equipment includes an instant heating device. The inlet and outlet of the instant heating device are respectively connected to an inlet pipe and an outlet pipe. A first temperature sensor and a second temperature sensor are respectively installed on the inlet pipe and the outlet pipe. An adjustable water pump is also installed on the inlet pipe. Figure 4 As shown, the control method for the drinking water equipment includes the following steps:

[0072] Step S110: When running the boiling water mode for the first time after each power-on, compare the set boiling point with the set heating temperature value.

[0073] Step S210: Determine the smaller value between the set boiling point and the set heating temperature value as the target heating temperature value.

[0074] Step S300: Obtain the inlet water temperature value.

[0075] Step S400: Heat the water flowing through the instant heating device according to the target heating temperature value.

[0076] Step S500: Obtain the outlet water temperature value.

[0077] Step S600: Determine whether the outlet water temperature is less than the target heating temperature. If so, proceed to step S721; otherwise, return to step S100.

[0078] Step S721: Increase the water flow rate of the instantaneous heating device and detect whether the outlet water temperature changes. After step S721, proceed to steps S722 and S723.

[0079] Step S722: If the outlet water temperature remains unchanged, update the set boiling point to the outlet water temperature value, and then return to step S100.

[0080] Step S723: If the outlet water temperature decreases, a fault warning message will be issued.

[0081] When the power is on, the water dispenser's location typically remains unchanged, and the actual boiling point of the water remains constant. For water dispensers with boiling water, tea-making, honey water, milk-making, and warm water modes, the temperature of warm water is usually lower than the boiling point of water in each region. Therefore, during the use of water dispensers in various regions, when operating the tea-making, honey water, milk-making, or warm water modes, the water is unlikely to be heated to boiling point, producing a large amount of high-temperature steam. This control method reduces the occurrence of large amounts of high-temperature steam ejected from the water outlet, provides alerts to users when the instant heating device malfunctions for timely repair, and avoids performing the aforementioned steps every time the boiling water mode is run, reducing the controller's workload and extending its lifespan.

[0082] In a fourth specific embodiment of the present invention, the drinking water equipment includes an instant heating device and a water storage device. The inlet of the instant heating device is connected to an inlet pipe, and the outlet of the instant heating device is connected to an outlet pipe and a drainage pipe respectively through a three-way valve. The downstream end of the drainage pipe is connected to the water storage device. A first temperature sensor is installed on the inlet pipe, and a second temperature sensor is installed at the outlet of the instant heating device. A water pump with adjustable flow rate is also installed on the inlet pipe. Figure 5 As shown, the control method for the drinking water equipment includes the following steps:

[0083] Step S110: When running the boiling water mode for the first time after each power-on, compare the set boiling point with the set heating temperature value.

[0084] Step S210: Determine the smaller value between the set boiling point and the set heating temperature value as the target heating temperature value.

[0085] Step S300: Obtain the inlet water temperature value.

[0086] Step S400: Heat the water flowing through the instant heating device according to the target heating temperature value.

[0087] Step S500: Obtain the outlet water temperature value.

[0088] Step S600: Determine whether the outlet water temperature is less than the target heating temperature. If so, proceed to step S731; otherwise, proceed to step S735.

[0089] Step S731: Connect the outlet of the instant heating device to the drainage pipe.

[0090] Specifically, the outlet of the instant heating device is connected to the drainage pipeline by controlling the state of the three-way valve.

[0091] Step S732: Increase the water flow rate of the instantaneous heating device and detect whether the outlet water temperature changes. After step S732, proceed to steps S733 and S734.

[0092] Step S733: If the outlet water temperature remains unchanged, update the set boiling point to the outlet water temperature value, and then return to step S110.

[0093] Step S734: If the outlet water temperature decreases, a fault message will be issued.

[0094] Step S735: Connect the outlet of the instant heating device to the water outlet pipe.

[0095] Specifically, the outlet of the instant heating device is connected to the water outlet pipe by controlling the state of the three-way valve.

[0096] With this setting, when the actual boiling point is lower than the target heating temperature, if the outlet water temperature is lower than the target heating temperature when heating water flowing through the instant heating device according to the target heating temperature, the state of the three-way valve is adjusted to connect the outlet of the instant heating device with the diversion pipe. Then, the water flow rate through the instant heating device is increased and the outlet water temperature is detected. Based on the detection results, the set boiling point is selectively updated to the outlet water temperature value. This can avoid the situation where high-temperature steam is ejected from the outlet of the water pipe in the short period of time before the set boiling point is updated, thus effectively preventing the situation where high-temperature steam is ejected from the outlet of the water pipe.

[0097] It should be noted that using a three-way valve to selectively connect the outlet of the instant heating device to either the inlet pipe or the outlet pipe is only one possible setup. In practical applications, adjustments can be made. For example, the upstream ends of both the inlet and outlet pipes can be connected to the outlet of the instant heating device, with a first valve and a second valve installed on each pipe. The connection between the outlet and either pipe can be controlled by opening and closing these valves. Alternatively, the water storage device can be a separate tank that needs to be manually emptied when it reaches a certain level. A water pump can also be installed in the tank, connected to the inlet pipe via a return pipe. During water supply to the instant heating device, the pump can pump water from the tank to the device.

[0098] In some other feasible embodiments, unlike the embodiments described above, the phrase "determine the smaller of the set boiling point and the set heating temperature value as the target heating temperature value" in the above embodiments is replaced with "if the set heating temperature value is less than the set boiling point, then the set heating temperature value is determined as the target heating temperature value; if the set heating temperature value is not less than the set boiling point, then the result of subtracting a preset value (such as 1℃, 2℃, 3℃ or other suitable value) from the set heating temperature value is determined as the target heating temperature value".

[0099] This design prevents water vapor from spraying out of the outlet pipe when the water is heated to its boiling point.

[0100] In some other feasible embodiments, unlike the embodiments described above, the water dispenser adjusts the outlet water temperature by adjusting the power of the instant heating device. The step of "heating the water flowing through the instant heating device according to the target heating temperature value" specifically includes: calculating the target heating power based on the target heating temperature value, the inlet water temperature value, and the water flow rate, and controlling the instant heating device to heat the water flowing through it according to the target heating power. The step of "increasing the water flow rate through the instant heating device and detecting whether the outlet water temperature changes" is replaced with "decreasing the heating power of the instant heating device and detecting whether the outlet water temperature changes".

[0101] Based on the above embodiments, preferably, the control method of the drinking water equipment further includes: while updating the set boiling point to the outlet water temperature value, issuing a prompt message to the user that the actual boiling point is lower than the target outlet water temperature, so as to avoid the situation where the outlet water temperature does not reach the set outlet water temperature value after the operation of updating the set boiling point due to the actual boiling point being lower than the target outlet water temperature, resulting in the user blindly complaining.

[0102] On the other hand, the present invention also provides a drinking water device, the controller of which includes a memory; a processor; and a computer program, the computer program being stored in the memory and configured to be executed by the processor as the control method of the drinking water device in any of the above embodiments.

[0103] It should be noted that the memory in the above embodiments includes, but is not limited to, random access memory, flash memory, read-only memory, programmable read-only memory, volatile memory, non-volatile memory, serial memory, parallel memory, or registers, etc., and the processor includes, but is not limited to, CPLD / FPGA, DSP, ARM processor, MIPS processor, etc. Furthermore, the water drinking device can be a water purifier, water dispenser, electric faucet, or other suitable water drinking device.

[0104] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
