[0002] Smart toilets can be cleaned, sterilized, odor-eliminated, and maintained by adding various liquids. A conventional way to add liquid is to set up a liquid storage chamber in the toilet and pour the liquid into the storage chamber through the liquid filling port. However, it is easy for the liquid to overflow due to misalignment with the liquid filling port or excessive liquid poured in. Another way to add liquid is to load the entire tank of liquid upward into the corresponding position of the toilet. When the liquid tank needs to be replaced, the liquid extraction tube needs to be removed and a new liquid tank needs to be connected. The operation is more complicated, and the liquid can easily contaminate the user's hands.

[0003] In the related art, the liquid tank is installed in an inverted manner into the toilet, and the sealing membrane of the liquid tank is pierced by puncturing the liquid tank, allowing the liquid in the liquid tank to flow out, thereby achieving convenient liquid addition, and the liquid tank can be replaced without leakage or pollution risks; however, since the upstream of the liquid extraction tube is full of liquid, the air downstream cannot enter the liquid tank through the liquid extraction tube, resulting in the air pressure in the liquid tank being unable to maintain balance with the external atmosphere, the liquid in the liquid tank cannot flow out of the liquid extraction tube, and the liquid discharge from the liquid tank is unstable.

[0041] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0042] Reference Figures 1 to 4 In an embodiment of the present invention, a smart toilet liquid adding structure 100 (hereinafter referred to as the liquid adding structure) is provided. The liquid adding structure 100 includes a mounting portion 110 and a liquid outlet portion 120. The mounting portion 110 is used to install and fix a liquid tank 10. The liquid tank 10 contains liquid, which can be foam liquid, electrolyzed water, medicinal liquid, etc. The liquid tank 10 is not limited to being made of glass or plastic. The liquid outlet portion 120 is used to take liquid to discharge the liquid in the liquid tank 10.

[0043] In one embodiment, the mounting portion 110 has a mounting cavity 111, and the mounting cavity 111 is used to place the liquid tank 10, and can limit and fix the liquid tank 10 so that the liquid tank 10 maintains a stable position in the mounting cavity 111; specifically, the upper end of the mounting cavity 111 passes through the top of the mounting portion 110 and forms a placement opening 112. The liquid tank 10 can be placed into the mounting cavity 111 from top to bottom through the placement opening 112, and the liquid tank 10 is inserted into the mounting cavity 111 with the opening facing downward. After the liquid tank 10 is installed, the opening of the liquid tank 10 is located at the bottom of the mounting cavity 111.

[0044] The liquid outlet portion 120 discharges the liquid in the liquid tank 10 by piercing the interior of the liquid tank 10. In one embodiment, the liquid outlet portion 120 includes a spike 121. It can be understood that the spike 121 should have a sharp end to facilitate piercing the liquid tank 10. The spike 121 extends upward from the bottom wall of the installation cavity 111. When the liquid tank 10 is inserted into the installation cavity 111, the spike 121 pierces the liquid tank 10 from bottom to top.

[0045] The liquid outlet part 120 includes a liquid outlet channel 122 and an air pressure compensation channel 123 that are isolated from each other. The liquid outlet channel 122 is used to discharge the liquid in the liquid tank 10, and the air pressure compensation channel 123 is used to connect the inner cavity of the liquid tank 10 with the external atmosphere to maintain air pressure balance between the liquid tank 10 and the external atmosphere. In one embodiment, the upper end of the liquid outlet channel 122 passes through the spike 121 and forms a liquid inlet 124. The lower end of the liquid outlet channel 122 extends to the outside of the installation cavity 111 and forms a liquid outlet 125. The liquid outlet 125 can be externally connected to the liquid extraction pipe 400. The liquid in the liquid tank 10 enters the liquid outlet channel 122 through the liquid inlet 124 and is discharged into the liquid extraction pipe 400 through the liquid outlet 125. The upper end of the air pressure compensation channel 123 passes through the spike 121 and forms an air outlet 126. The lower end of the air pressure compensation channel 123 extends to the outside of the installation cavity 111 and forms an air inlet 127. The air inlet 127 is connected to the external atmosphere.

[0046] Since the air pressure compensation channel 123 and the liquid outlet channel 122 are isolated from each other, the flow of air in the air pressure compensation channel 123 is not affected by the liquid in the liquid outlet channel 122. When the spike 121 penetrates the liquid tank 10, the external atmosphere is connected with the inner cavity of the liquid tank 10 through the air pressure compensation channel 123, and the air enters the liquid tank 10 through the air pressure compensation channel 123. The external atmosphere and the internal air pressure of the liquid tank 10 are kept balanced, and the liquid in the liquid tank 10 can flow into the liquid outlet channel 122 more smoothly, making the liquid discharge from the liquid tank 10 more stable.

[0047] It is understandable that in the present invention, the liquid tank 10 is installed in an inverted manner on the mounting portion 110. When the liquid tank 10 is inserted into the mounting cavity 111, the lid 11 does not need to be removed. After the liquid tank 10 is inserted into the mounting cavity 111, the pressure at the contact point between the spike 121 and the lid 11 is strong enough to easily pierce the lid 11 of the liquid tank 10. The external atmosphere maintains air pressure balance with the inner cavity of the liquid tank 10 through the air pressure compensation channel 123, allowing the liquid in the liquid tank 10 to be discharged more smoothly from the liquid outlet channel 122. The spike 121 can be made of a material such as resin or metal, so that the spike 121 has a certain hardness and can pierce the lid 11 of the liquid tank 10. When the liquid tank 10 needs to be replaced, the liquid tank 10 can be directly pulled out upwards and a new liquid tank 10 can be re-installed into the mounting cavity 111, making the replacement of the liquid tank 10 more convenient. The lid 11 of the liquid tank 10 is made of elastic materials such as silicone and rubber. After the spike 121 pierces the lid 11, the lid 11 wraps around the outer periphery of the spike 121 due to its own elasticity, so that the matching position of the spike 121 and the lid 11 remains sealed to prevent liquid leakage; and when the liquid in the liquid tank 10 is not used up and needs to be taken out, after the spike 121 exits the liquid tank 10, the opening on the lid 11 returns to a closed state under the action of the lid 11's own elasticity, and under the action of atmospheric pressure, the residual liquid in the liquid tank 10 will not leak out and cause pollution.

[0048] In addition, conventional technology adopts the method of pouring liquid into the liquid storage chamber of the toilet for adding liquid. When multiple liquids need to be added to the toilet, it is easy to cause the wrong liquid to be added because the same liquid adding method is used for multiple liquids. The utility model provides a method of installing the entire liquid tank 10 for adding liquid, which can reduce the risk of adding the wrong liquid; and liquid tanks 10 of different types of liquids can be contained in liquid tanks 10 of different shapes or specifications and sizes for easy distinction, further reducing the risk of mixing liquids and adding errors.

[0049] In one embodiment, the cross-section of the installation cavity 111 along the horizontal plane is set to be circular, that is, the installation cavity 111 is set to be a cylindrical cavity, the liquid tank 10 is cylindrical, and the lengths of the liquid tanks 10 containing different types of liquids are different for easy distinction. After different liquid tanks 10 are installed in the installation cavity 111, they can all be limited by the inner wall of the installation cavity 111, so that the liquid tank 10 maintains a stable position in the installation cavity 111. Alternatively, in another embodiment, the cross-section of the mounting cavity 111 along the horizontal plane is set to a regular polygon, and the liquid tanks 10 containing different types of liquids are cylindrical or prismatic for easy distinction. Different liquid tanks 10 can all be loaded into the mounting cavity 111 and can be limited by the inner wall of the mounting cavity 111; illustratively, the cross-section of the mounting cavity 111 along the horizontal plane is set to a regular quadrilateral. After the cylindrical liquid tank 10 is loaded into the mounting cavity 111, the circumferential surface of the liquid tank 10 can be tangent to and abut against the inner wall of the mounting cavity 111. After the quadrilateral liquid tank 10 is loaded into the mounting cavity 111, the side walls of the liquid tank 10 are parallel to and abut against the inner wall of the mounting cavity 111, so that the liquid tanks 10 containing different types of liquids can all be limited by the mounting cavity 111.

[0050] In addition, if Figure 4 The mounting portion 110 further includes at least one operating cavity 113, which is connected to the side of the mounting cavity 111. The top of the operating cavity 113 extends through the top of the mounting portion 110 and forms an operating opening 114. The operating opening 114 can be inserted by the user's hand to facilitate the insertion of the liquid tank 10 into the mounting cavity 111. It is understandable that when the height of the liquid tank 10 is less than the height of the mounting cavity 111, the liquid tank 10 can be completely inserted into the mounting cavity 111. During use, the liquid tank 10 will not protrude outside the mounting cavity 111, so that the appearance of the liquid adding structure 100 remains neat. However, the process of the user inserting the liquid tank 10 into the mounting cavity 111 is inconvenient. By providing the operating cavity 113 on the side of the mounting cavity 111, the user can hold the liquid tank 10 with his hand when installing the liquid tank 10. When the user's hand is inserted into the operating cavity 113, the liquid tank 10 can be inserted into the mounting cavity 111, making the installation of the liquid tank 10 more convenient. In one embodiment, the lower end of the operating cavity 113 is set higher than the lower end of the installation cavity 111, so that the entire circumference of the liquid tank 10 can be limited by the inner wall of the installation cavity 111, reducing the impact of the setting of the operating cavity 113 on the position stability of the liquid tank 10.

[0051] Furthermore, a spike 121 is arranged at the center of the bottom wall of the installation cavity 111. On the one hand, the central area of ​​the lid 11 of the liquid tank 10 has greater elasticity, and the spike 121 can penetrate into the liquid tank 10 from the central area of ​​the lid 11 more smoothly, and the lid 11 can tightly wrap the spike 121 for sealing. On the other hand, the spike 121 located in the central area can adapt to the penetration requirements of liquid tanks 10 of different shapes and sizes.

[0052] In one embodiment, the mounting portion 110 and the liquid outlet portion 120 are configured as an integrally molded structure, such that the connection between the spike 121 and the bottom wall of the mounting cavity 111 is sealed. For example, the mounting portion 110 and the liquid outlet portion 120 are integrally molded by injection molding. In one embodiment, the liquid outlet channel 122 and the air pressure compensation channel 123 are arranged side by side and fixed to each other by bonding, with the spike 121 connected to the top of the liquid outlet channel 122 and the air pressure compensation channel 123. In another embodiment, the liquid outlet channel 122 and the compensation channel are integrally connected, and the two can be formed into an integral structure by injection molding.

[0053] For example, refer to Figure 3 and Figure 4 The liquid outlet portion 120 includes a channel body 128 and a partition wall 129 located within the channel body 128. The partition wall 129 separates the inner cavity of the channel body 128 into a liquid outlet channel 122 and an air pressure compensation channel 123. That is, the liquid outlet channel 122 and the air pressure compensation channel 123 are both located within the channel body 128 and isolated from each other. The liquid outlet channel 122 only allows the liquid in the liquid tank 10 to flow, and the air pressure compensation channel 123 only allows the external atmosphere to enter the liquid tank 10. The liquid outlet channel 122 and the air pressure compensation channel 123 share the partition wall 129, which keeps the appearance of the channel body 128 neat and tidy, simplifies the structure of the liquid outlet portion 120, and facilitates the processing of the liquid adding structure 100.

[0054] In one embodiment, the isolation wall 129 extends vertically and isolates a liquid outlet channel 122 and an air pressure compensation channel 123, both of which extend vertically, in the channel body 128. The air inlet 127 and the liquid outlet 125 can both be set as the lower end of the channel body 128; in order to facilitate the installation of the liquid extraction tube 400 at the liquid outlet 125 and avoid the air inlet 127 so that external air can smoothly enter the air pressure compensation channel 123, the liquid outlet 125 can be set lower than the air inlet 127, and the lower end of the liquid outlet channel 122 protrudes downward relative to the air pressure compensation channel 123, and the protruding part can be used for connection of the liquid extraction tube 400.

[0055] Alternatively, in another embodiment, the lower end of the isolation wall 129 is higher than the lower end of the channel body 128, the air inlet 127 is located at the side of the channel body 128, and the liquid outlet 125 is located at the lower end of the channel body 128. Part of the isolation wall 129 extends vertically, and part of the isolation wall 129 extends horizontally, that is, the isolation wall 129 can be set to an "L" shape; the air inlet 127 and the liquid outlet 125 are respectively located at the end and the side of the channel body 128, and the two avoid each other. On the one hand, it is convenient for the liquid extraction tube 400 to be installed at the liquid outlet 125, and the external atmosphere can enter the air compensation channel through the air inlet 127 more smoothly. On the other hand, since the lower end of the channel body 128 is higher than the lower end of the isolation wall 129, the lower section of the liquid outlet channel 122 has a larger diameter, which is convenient for installation to the channel body 128, and the flow of liquid in the liquid outlet channel 122 is smoother; for example, in one embodiment, the liquid extraction tube 400 is plugged into the channel body 128, and the lower end of the channel body 128 is inserted into the liquid extraction tube 400, so that the liquid outlet 125 is connected to the liquid extraction tube 400.

[0056] The liquid outlet portion 120 further includes an extension section 1210, which is connected to the side of the channel body 128 and extends away from the channel body 128. An airflow channel 1211 is defined within the extension section 1210. One end of the airflow channel 1211 is connected to the air inlet 127, and the other end is connected to the outside atmosphere. External air can enter the air pressure compensation channel 123 through the airflow channel 1211 and the air inlet 127. The liquid outlet portion 120 draws air from the side and discharges liquid from the bottom. The provision of the extension section 1210 limits the insertion depth of the liquid extraction tube 400 into the channel body 128, preventing the channel body 128 from being inserted too deeply into the liquid extraction process, which would cause the liquid extraction tube 400 to block the air inlet 127. This ensures that the air pressure compensation channel 123 remains connected to the outside atmosphere.

[0057] In one embodiment, the spike 121 is configured to be conical, and the peripheral surface of the spike 121 is a conical surface, so that the upper end of the spike 121 is sharp and the peripheral side is smooth, so that the spike 121 can smoothly penetrate into the interior of the liquid tank 10; further, the conical surface of the spike 121 has a larger area for the liquid inlet 124 and the air outlet 126 to be set, which is conducive to increasing the opening of the liquid inlet 124 and the air outlet 126.

[0058] In one embodiment, the air outlet 126 is set higher than the liquid inlet 124. On the one hand, the height of the air outlet 126 is higher, and when the air in the air pressure compensation channel 123 enters the liquid tank 10, the water pressure overcome is smaller, and the air can enter the liquid tank 10 more smoothly. On the other hand, the position of the liquid inlet 124 is lower, which facilitates the liquid in the liquid tank 10 to enter the liquid outlet channel 122 and can reduce the liquid residue in the liquid tank 10.

[0059] Furthermore, the spike 121 includes a piercing section 1212 and a liquid-passing section 1213 arranged side by side, the piercing section 1212 protrudes upward compared to the liquid-passing section 1213, the liquid inlet 124 is arranged at the top of the liquid-passing section 1213, the piercing section 1212 has a conical surface on the side facing away from the liquid-passing section 1213, the air outlet 126 is arranged on the conical surface, the upper end of the piercing section 1212 is higher than the liquid-passing section 1213, and has a sharp tip, which can first pierce the interior of the liquid tank 10, and the liquid-passing section 1213 follows the piercing Segment 1212 is then inserted into the liquid tank 10, allowing the external atmosphere to enter the liquid tank 10 through the air outlet 126, and the liquid in the liquid tank 10 is discharged through the liquid inlet 124; it can be understood that by piercing the liquid tank 10 with segment 1212, the contact area between the spike 121 and the lid 11 of the liquid tank 10 is reduced, and the lid 11 of the liquid tank 10 is easier to pierce, and the air outlet 126 can be higher than the liquid inlet 124, which reduces the water pressure that the air needs to overcome to enter the liquid tank 10 and can reduce the liquid residue in the liquid tank 10.

[0060] It should be noted that "the piercing section 1212 has a conical surface" means that the piercing section 1212 has at least a part of the conical surface, and does not limit the piercing section 1212 to have the entire conical surface; in one embodiment, the piercing section 1212 and the liquid passage section 1213 together form the same cone, and the outer wall surfaces of the two are both part of the conical surface.

[0061] In addition, part of the channel body 128 is inserted into the interior of the installation cavity 111, and the spike 121 is connected to the top of the channel body 128. After the spike 121 pierces the lid 11 and enters the interior of the liquid tank 10, part of the channel body 128 can be plugged into the lid 11 to ensure that the spike 121 is completely inserted into the inner cavity of the liquid tank 10, and the liquid inlet 124 and the air outlet 126 are completely exposed inside the liquid tank 10, so that external air can enter the liquid tank 10 more smoothly and reduce the liquid residue in the liquid tank 10.

[0062] Reference Figure 1 and Figure 2 The present invention also provides a smart toilet, which includes a housing 200 and a toilet body 300. The housing 200 is sealed on the top of the toilet body 300. The toilet body 300 is configured to have a toilet bowl and can be installed with other modules. The housing 200 can protect the modules installed on the toilet body 300. The above-mentioned liquid adding structure 100 can be set in the housing 200. The smart toilet also includes a liquid extraction tube 400. One end of the liquid extraction tube 400 is connected to the liquid outlet 120 and communicates with the liquid outlet 125. The other end is used to discharge liquid in the liquid tank 10. After the liquid tank 10 is installed in the housing 200 through the liquid adding structure 100, the liquid is discharged from the liquid outlet 125 into the liquid extraction tube 400 and then discharged from the liquid extraction tube 400.

[0063] The manner in which the liquid adding structure 100 is arranged on the shell 200 is not limited to that the liquid adding structure 100 is integrally connected to the shell 200, or that a mounting position for installing the liquid adding structure 100 is provided on the shell 200, and the liquid adding structure 100 is installed on the shell 200. The mounting position on the shell 200 for installing the liquid adding structure 100 is not limited to a groove, a hole, a snap-fit ​​structure, a column, etc.

[0064] In one embodiment, the liquid adding structure 100 is integrally connected to the shell 200 and is located at the top of the shell 200, that is, the liquid adding structure 100 is integrated on the shell 200 and is installed on the toilet body 300 as a whole with the shell 200. Since the liquid adding structure 100 is located at the top of the shell 200, the placement port 112 passes through the top of the shell 200, and the liquid tank 10 can be directly installed from top to bottom into the installation cavity 111 in the shell 200. When replacing the liquid tank 10, the liquid tank 10 can be directly pulled out upwards, and the disassembly and assembly of the liquid tank 10 is relatively convenient.

[0065] Alternatively, in another embodiment, the housing 200 includes an upper cover and a bottom plate, the liquid adding structure 100 is integrally connected to the bottom plate, the upper cover is located above the bottom plate, and blocks the placement opening 112. The upper cover can prevent impurities in the external air from entering the installation cavity 111 and contaminating the installation cavity 111, thereby ensuring the cleanliness of the liquid discharged from the liquid tank 10. Furthermore, the upper cover can be configured to rotate relative to the bottom plate, and by rotating the upper cover, the upper cover can be removed from blocking the placement opening 112, facilitating replacement of the liquid tank 10; alternatively, the upper cover is provided with an openable and closable cover body, which is located above the storage opening. When the cover body is open, the storage opening is unobstructed, allowing the liquid tank 10 to be replaced. When the cover body is closed, the cover body blocks the liquid tank 10 and prevents impurities from entering the installation cavity 111.

[0066] It should be noted that the liquid discharge method of the liquid tank 10 in the present invention is not limited to relying on gravity, pumping, negative pressure guidance, etc. In one embodiment, if Figure 5 In Figure (a), the air outlet 126 is higher than the liquid inlet 124. After the air enters the liquid tank 10 through the liquid inlet 124, it accumulates in the upper part of the liquid tank 10. Under the action of the air pressure in the liquid tank 10 and the gravity of the liquid itself, the liquid is discharged into the liquid outlet channel 122 through the liquid inlet 124 and discharged through the liquid extraction pipe 400.

[0067] Or, in another embodiment, referring to Figure 5In Figure (b), the smart toilet also includes a liquid pump 500, which is connected to the liquid extraction tube 400 and is used to extract the liquid in the liquid tank 10 and allow the liquid to enter the liquid extraction tube 400. Since the liquid tank 10 can always maintain air pressure equilibrium with the external atmosphere through the air pressure compensation channel 123 and relies on the liquid pump 500 to extract liquid, and the liquid pump 500 only extracts liquid through the liquid extraction tube 400, and the liquid extraction tube 400 is only connected to the liquid outlet 125, when the liquid pump 500 extracts liquid, the liquid in the liquid tank 10 will only be discharged from the liquid outlet channel 122, and will not enter the air pressure compensation channel 123, causing leakage.

[0068] In addition, since the flow rate of the liquid pump 500 is controllable, the liquid can be pumped quantitatively by adjusting the single running time of the liquid pump 500; and since the liquid storage volume of the liquid tank 10 is controllable, the flow rate of the liquid pump 500 is controllable, and the remaining liquid volume in the liquid tank 10 can be judged by collecting the cumulative running time of the liquid pump 500. When the remaining liquid volume in the liquid tank 10 is insufficient, the user can be reminded to replace it; or, when the liquid in the liquid tank 10 is salt water, and the liquid is added to the electrolysis device for electrolysis, since the amount of added liquid will affect the resistance of the electrolyte in the electrolysis device, the remaining liquid volume in the liquid tank 10 can be judged by detecting the voltage or current during electrolysis, and then the user can be reminded to replace it; of course, the remaining liquid volume in the liquid tank 10 can also be detected by setting an infrared sensor, microwave sensor, etc. at the installation position of the liquid tank 10.

[0069] Alternatively, in another embodiment, the smart toilet includes a negative pressure generating device, which is connected to the end of the liquid extraction tube 400 away from the liquid outlet 120. The negative pressure generating device is used to generate negative pressure at the end of the liquid extraction tube 400 away from the liquid outlet 120. Since the air pressure in the liquid tank 10 is always balanced with the external atmosphere, when one end of the liquid extraction tube 400 has a negative pressure, under the action of the air pressure in the liquid tank 10, the liquid in the liquid tank 10 will continue to flow toward the liquid extraction tube 400 and be discharged from the liquid extraction tube 400; after the liquid in the liquid tank 10 flows out, external air can enter the liquid tank 10 through the air pressure compensation channel 123, thereby replenishing the air pressure in the liquid tank 10, so that the air pressure in the liquid tank 10 remains balanced, ensuring that the liquid in the liquid tank 10 can flow out continuously and stably.

[0070] The negative pressure generating device is not limited to the method of generating negative pressure at the end of the liquid extraction pipe 400 by introducing water flow or air flow into the end of the liquid extraction pipe 400. According to Bernoulli's theorem, the flow of fluid at the end of the liquid extraction pipe 400 generates negative pressure and guides the liquid in the liquid tank 10 to flow out. Exemplarily, the negative pressure generating device is configured as a three-way structure connected to the end of the liquid extraction pipe 400. When water is passed through the three-way structure at the end of the liquid extraction pipe 400, the liquid in the liquid tank 10 flows out and mixes with the water introduced into the three-way structure. In one embodiment, the liquid in the liquid tank 10 is foam liquid. When water is passed through the three-way structure at the end of the liquid extraction pipe 400, the foam liquid flows from the liquid tank 10 into the liquid extraction pipe 400 and mixes with water at the end of the liquid extraction pipe 400 to form a mixed fluid, thereby generating foam.

[0071] In one embodiment, referring to Figure 6 The smart toilet also includes an electrolytic atomization device 600. The liquid extraction tube 400 is connected to the electrolytic atomization device 600 and transports the liquid in the liquid tank 10 to the electrolytic atomization device 600 for electrolysis. After the liquid is electrolyzed, it is discharged from the other end of the liquid extraction tube 400. The electrolytic atomization device 600 can dilute and atomize the liquid transported by the liquid extraction tube 400 to make the liquid discharged from the liquid extraction tube 400 more uniform, or electrolyze the liquid transported by the liquid extraction tube 400 to prepare a disinfectant through an electrochemical reaction, and then discharge it from the liquid extraction tube 400.

[0072] In addition, the end of the liquid extraction tube 400 away from the liquid outlet 120 can also be connected to a spray gun 700. When liquid medicine is added to the liquid tank 10, it can be sprayed in a directional manner through the spray gun 700 to achieve a therapeutic or nursing effect.

However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
