[0002] In the installation-free drinking water equipment, a water tank is set up to store purified water for drinking. The water tank has an exhaust port to allow air to enter the water tank from the exhaust port to balance the air pressure inside and outside the water tank. Since air can enter the water tank, dust, bacteria and other substances in the air will cause secondary pollution to the water tank and breed bacteria. In addition, the water tank is generally set inside the drinking water equipment, which is difficult to clean. Long-term use will seriously affect the water quality of the drinking water equipment and pose a threat to the health of users. Existing drinking water equipment is generally provided with a sterilization mode, which sterilizes the water tank at high temperature by flowing boiling water in the water tank.

[0008] In the preferred technical solution of the above-mentioned water system, the water outlet includes a water outlet pipe and a shell arranged outside the water outlet pipe, the water outlet pipe is connected to the water outlet cavity, and there is a gap between the shell and the water outlet pipe. When the sealing is completed, one end of the sealing component is located in the gap, and the other end of the sealing component seals the water outlet pipe. The locking component is located outside the sealing component and is fixedly connected to the shell to lock the sealing component to the water outlet pipe.

[0009] In the preferred technical solution of the above-mentioned water system, a spray assembly is provided in the water tank, and the spray assembly is connected to the exhaust pipe. The spray assembly can spray the water flowing from the exhaust pipe toward the top wall and the side wall of the water tank so as to sterilize the top wall and the side wall of the water tank.

[0015] In a second aspect, the present invention provides a drinking water device, and the drinking water device of the present invention includes the water channel system.

[0016] When adopting the above technical scheme, the drinking water equipment of the present invention includes a water intake mode and a sterilization mode. The water system of the present invention includes a water tank, a heating component, a water pump, a water outlet component, an exhaust pipe and a sealing component. The water outlet component includes a water outlet chamber and a water outlet nozzle. When the drinking water equipment is in the water intake mode, the sealing component is separated from the water outlet nozzle, and the steam generated in the water tank can pass through the exhaust pipe and be discharged through the water outlet nozzle, and the water in the water tank can flow out of the water outlet nozzle through the water outlet chamber; when the drinking water equipment is in the sterilization mode, the sealing component can seal the water outlet nozzle, so that the water in the water outlet chamber flows through the water outlet nozzle and cannot flow out of the water outlet nozzle, so that the water in the water outlet chamber can flow back into the water tank through the exhaust pipe. Through such an arrangement, the drinking water device of the present invention can sterilize the water spout with hot water, and in the process of sterilizing the water spout, the water spout is sealed by the sealing component. On the one hand, it can prevent hot water from flowing out of the water spout, thereby avoiding scalding the user by the flowing hot water. On the other hand, it can also make the hot water in the water outlet cavity flow back into the water tank through the exhaust pipe, thereby also sterilizing the water tank with hot water, making the sterilization more thorough and improving the user experience.

[0017] Furthermore, by configuring the sealing component as a sealing member and a locking member, and by configuring the sealing member to be sleeved on the outside of the water outlet, the sealing between the sealing component and the water outlet can be improved, thereby more effectively preventing hot water from flowing out of the water outlet during the sterilization process of the water outlet. By locking the sealing member on the water outlet through the locking member, the stability of the connection between the sealing component and the water outlet can be improved, thereby preventing the sealing component from falling off the water outlet during the sterilization process of the water outlet.

[0018] Furthermore, the water outlet is configured as a water outlet pipe and a shell arranged outside the water outlet pipe, and there is a gap between the shell and the water outlet pipe. Compared with configuring the water outlet only as a water outlet pipe, the installation of the blocking component on the water outlet is simpler and more convenient, thereby improving the installation and disassembly efficiency of the blocking component on the water outlet, greatly saving the user's operation time before and after sterilizing the drinking water equipment, and further improving the user's experience.

[0019] Furthermore, by arranging a spray assembly in the water tank and connecting the spray assembly with the exhaust pipe, the water in the water outlet chamber can enter the spray assembly through the exhaust pipe, and the water flowing from the exhaust pipe can be sprayed toward the top wall and side walls of the water tank through the spray assembly, thereby facilitating the sterilization of the top wall and side walls of the water tank, making the sterilization of the water tank more thorough, preventing the growth of bacteria in the water tank due to the inability to sterilize the top wall and side walls of the water tank, avoiding affecting the user's water health, and further improving the user's experience.

[0020] Furthermore, by configuring the spray assembly as a vertical pipe and a spray pipe, and arranging a water inlet component in the vertical pipe, on the one hand, it is possible to enable the water that enters from the exhaust pipe to the bottom of the water inlet component to enter the top of the water inlet component through the water inlet component and quickly spray toward the spray pipe, thereby sterilizing the top wall and side walls of the water tank; on the other hand, the structure of the drinking water equipment is simpler. Compared with configuring the spray assembly as a booster pump and a spray pipe, the production cost of the drinking water equipment can be greatly reduced because the use of the booster pump is saved.

[0021] Furthermore, through the setting of the driving component, the water inlet component can be automatically driven to move up and down in the vertical direction in the vertical pipe without the need for manual operation by the user, thereby facilitating the automatic sterilization of the top wall and side walls of the water tank, making the sterilization of the drinking water equipment more intelligent.

[0022] Furthermore, the water inlet component is configured as a water inlet plate, and a plurality of water inlet holes and a cover plate corresponding to the water inlet holes are arranged on the water inlet plate, so that the structure of the water inlet component is simpler and more convenient to use. At the same time, the failure rate of the drinking water equipment is reduced by avoiding the use of a control valve.

[0023] Furthermore, the driving component is arranged above the water inlet component, and the output end of the driving component is fixedly connected to the top of the water inlet component. Compared with arranging the driving component below the water inlet component, arranging the driving component above the water inlet component does not need to consider the sealing of the vertical pipe affected by the installation of the driving component, and therefore the installation is simpler.

[0024] In addition, based on the above-mentioned technical solution, the present invention further provides a drinking water equipment, which adopts the above-mentioned water system for drinking water equipment and thus has the technical effects of the above-mentioned water system. Compared with the drinking water equipment before the improvement, the drinking water equipment of the present invention can sterilize more thoroughly, the water used during use is safer, and the user experience is better.

[0043] Based on the problem pointed out in the background art that the existing drinking water equipment cannot sterilize the water spout during high temperature sterilization, resulting in incomplete sterilization and affecting the user experience, the present invention provides a water channel system for drinking water equipment, aiming to enable the drinking water equipment of the present invention to sterilize the water spout with hot water.

[0044] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the connection structure of the waterway system of the present invention, Figure 2 It is a structural schematic diagram of the drinking water equipment of the present invention.

[0045] like Figure 1 and Figure 2 As shown, the water system of the drinking water equipment 1 of the present invention includes a water tank 11, a heating component 12, a water pump 13, a water outlet component 14, an exhaust pipe 15 and a blocking component 16. Drinking water is stored in the water tank 11. The heating component 12 has a heating chamber 121, which is connected to the water tank 11. The heating component 12 can heat the water in the heating chamber 121. The water pump 13 is respectively connected to the water tank 11 and the heating chamber 121 so as to transport the water in the water tank 11 to the heating chamber 121. The water outlet component 14 includes a connected water outlet chamber 141 and a water outlet nozzle 142. The water outlet chamber 141 is connected to the heating chamber 121 so that the water in the heating chamber 121 enters the water outlet chamber 141. Both ends of the exhaust pipe 15 are respectively connected to the water tank 11 and the water outlet chamber 141. The blocking component 16 can block the water outlet nozzle 142 to prevent the water in the water outlet chamber 141 from flowing out of the water outlet nozzle 142.

[0046] The drinking water equipment 1 of the present invention has a water intake mode and a sterilization mode. When the drinking water equipment 1 is in the water intake mode, the blocking component 16 is separated from the water outlet 142, and the steam generated in the water tank 11 can pass through the exhaust pipe 15 and be discharged through the water outlet 142. The water in the water tank 11 can flow out of the water outlet 142 through the water outlet cavity 141. When the drinking water equipment 1 is in the sterilization mode, the blocking component 16 can block the water outlet 142 to prevent the water in the water outlet cavity 141 from flowing out of the water outlet 142, so that the water in the water outlet cavity 141 can flow back into the water tank 11 through the exhaust pipe 15.

[0047] By such an arrangement, that is, by arranging a blocking component 16 at the water outlet 142, the drinking water device 1 of the present invention can sterilize the water outlet 142 with hot water, and in the process of sterilizing the water outlet 142, the water outlet 142 is blocked by the blocking component 16. On the one hand, it can prevent the hot water in the water outlet cavity 141 from flowing out of the water outlet 142, thereby avoiding scalding the user by the flowing hot water. On the other hand, it can also make the hot water in the water outlet cavity 141 flow back into the water tank 11 through the exhaust pipe 15, so that the hot water forms a circulation between the water tank 11 and the water outlet 142, thereby also being able to sterilize the water tank 11 with hot water, making the sterilization more thorough and improving the user's experience.

[0048] It should be noted that, in actual applications, those skilled in the art may configure the heating component 12 to be a resistive heating structure, or may configure the heating component 12 to be an electromagnetic heating structure, etc. Such adjustments and changes to the specific setting type of the heating component 12 do not deviate from the principles and scope of the present invention, and should be included in the protection scope of the present invention.

[0049] Preferably, the heating assembly 12 is configured as a resistive heating structure.

[0050] It should be noted that in practical applications, the water pump 13 is not limited to the above-mentioned form of being arranged between the water tank 11 and the heating component 12. For example, the water pump 13 can also be arranged between the heating component 12 and the water outlet component 14, etc. Such adjustment and change of the specific arrangement position of the water pump 13 does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention. Of course, preferably, the water pump 13 is arranged between the water tank 11 and the heating component 12.

[0051] It should also be noted that, in actual applications, those skilled in the art may configure the water outlet component 14 to be a water outlet chamber 141 and a water outlet nozzle 142, the water outlet chamber 141 being connected to the heating chamber 121, the water outlet nozzle 142 and the exhaust pipe 15, respectively; or, the water outlet component 14 may be configured to be a water outlet pipe and a water outlet nozzle 142, the water outlet pipe being connected to the heating chamber 121, the water outlet nozzle 142 and the exhaust pipe 15, respectively; or, the water outlet component 14 may be configured to be a three-way pipe, the three interfaces of the three-way pipe being connected to the heating chamber 121, the water outlet nozzle 142 and the exhaust pipe 15, respectively, and so on. Such adjustments and changes to the specific structural form of the water outlet component 14 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0052] Preferably, if Figure 1 As shown, the water outlet assembly 14 is configured to include a water outlet chamber 141 and a water outlet nozzle 142 , and the water outlet chamber 141 is communicated with the heating chamber 121 , the water outlet nozzle 142 and the exhaust pipe 15 , respectively.

[0053] Through such an arrangement, when the sealing component 16 is separated from the water outlet nozzle 142, the steam generated in the water tank 11 can be discharged from the water outlet nozzle 142 through the exhaust pipe 15. At the same time, the exhaust pipe 15 can balance the air pressure inside and outside the water tank 11. When the drinking water equipment 1 is in the water intake mode, the water in the water tank 11 is transported to the heating chamber 121, and then transported to the water outlet chamber 141, and discharged from the water outlet nozzle 142 to achieve water intake; when the drinking water equipment 1 is in the sterilization mode, the water outlet nozzle 142 is blocked by the sealing component 16, the water in the water tank 11 is transported to the heating chamber 121 for heating, the water pump 13 transports the hot water in the heating chamber 121 to the water outlet chamber 141, and sends it back to the water tank 11 through the exhaust pipe 15, forming a hot water circulation flow, thereby performing high-temperature sterilization on the water system.

[0054] It should be noted that when the drinking water device 1 is in the water intake mode, the water in the water tank 11 can be transported to the water outlet chamber 141 through the water pump 13, and then flow out through the water outlet nozzle 142 to achieve water intake, or, gravity can be used to make the water in the water tank 11 enter the water outlet chamber 141, and then flow out through the water outlet nozzle 142 to achieve water intake, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0055] Continue reading Figure 2 , and then see Figures 3 to 9 , Figure 3 yes Figure 2 A partial enlarged schematic diagram of the portion A in the middle shows the positional relationship of the various components when the plugging assembly plugs the water outlet; Figure 4 yes Figure 3 A schematic diagram of the structure after the middle locking member is hidden; Figure 5 yes Figure 3 A schematic diagram of the structure after the locking member and the connecting member are hidden; Figure 6 yes Figure 3 A schematic diagram of the structure after the locking member, the sealing member and the connecting member are hidden; Figure 7 Schematic diagram of the three-dimensional structure of the sealing member of the present invention Figure 1 ; Figure 8 Schematic diagram of the three-dimensional structure of the sealing member of the present invention Figure 2 ; Fig. 9 It is a three-dimensional structural schematic diagram of the locking component of the present invention.

[0056] Preferably, if Figures 2 to 9 As shown, the sealing assembly 16 includes a sealing member 161 and a locking member 162. The sealing member 161 can be sleeved on the outside of the water outlet 142 to seal the water outlet 142, and the locking member 162 can lock the sealing member 161 to the water outlet 142 to prevent the sealing member 161 from falling off from the outside of the water outlet 142.

[0057] Through such a configuration, on the one hand, the sealing between the sealing component 16 and the water outlet 142 can be improved by putting the sealing component 161 on the outside of the water outlet 142, thereby more effectively preventing hot water from flowing out of the water outlet 142 during the sterilization process of the water outlet 142; on the other hand, the locking component 162 can lock the sealing component 161 to the water outlet 142, thereby improving the connection stability between the sealing component 16 and the water outlet 142, preventing the sealing component 161 from falling off from the water outlet 142 during the execution of the sterilization mode of the drinking water equipment 1, avoiding high-temperature water from flowing out of the water outlet 142 and causing burns, thereby further improving the safety of the equipment.

[0058] It should be noted that, in practical applications, the sealing member 161 is not limited to being set to be sleeved on the outside of the water outlet 142 to seal the water outlet 142. For example, the sealing member 161 can also be set to be inserted into the inside of the water outlet 142 to seal the water outlet 142, etc. Such adjustment and change of the specific blocking method of the sealing member 161 to the water outlet 142 does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention. Of course, preferably, the sealing member 161 is set to be sleeved on the outside of the water outlet 142 to seal the water outlet 142.

[0059] It should also be noted that, in actual applications, those skilled in the art may configure the locking member 162 as a locking sleeve mounted on the outside of the sealing member 161, or may configure the locking member 162 as a locking piece arranged on the sealing member 161, or may directly configure the locking member 162 as a locking portion such as a threaded portion opened on the sealing member 161, and so on. Such adjustments and changes to the specific structural form of the locking member 162 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0060] Preferably, if Figure 2 , Figure 3 and Fig. 9 As shown, the locking member 162 is configured as a locking sleeve that is sleeved on the outside of the sealing member 161 .

[0061] Through such a configuration, the sealing component 161 can make the sealing of the water outlet 142 more secure and have better sealing performance. At the same time, when the sealing component 161 is replaced, the locking component 162 can be reused, thereby reducing the user's usage cost.

[0062] It should be noted that, in actual applications, those skilled in the art may directly set the water outlet 142 to be the water outlet pipe 1421, or, may set the water outlet 142 to be the water outlet pipe 1421 and a shell 1422 arranged outside the water outlet pipe 1421, and so on. Such adjustments and changes to the specific setting type of the water outlet 142 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0063] Preferably, if Figures 3 to 9 As shown, the water outlet nozzle 142 includes a water outlet pipe 1421 and a shell 1422 arranged outside the water outlet pipe 1421, the water outlet pipe 1421 is connected to the water outlet chamber 141, and there is a gap 1423 between the shell 1422 and the water outlet pipe 1421, and the sealing member 161 includes a sealing end 1611 and an open end 1612. When the sealing is completed, the open end 1612 of the sealing member 161 is located in the gap 1423, and the sealing end 1611 of the sealing member 161 seals the water outlet pipe 1421. The locking member 162 is located outside the sealing member 161 and is fixedly connected to the shell 1422 to lock the sealing member 161 to the water outlet pipe 1421.

[0064] Through such a setting, that is, by installing the open end 1612 of the sealing component 161 in the gap 1423, and then locking the sealing component 161 on the water outlet pipe 1421 through the locking component 162, compared with setting the water outlet 142 only as the water outlet pipe 1421, the installation of the blocking component 16 on the water outlet 142 is simpler and more convenient, thereby improving the installation and disassembly efficiency of the blocking component 16 on the water outlet 142, greatly saving the user's operation time before and after sterilizing the drinking water equipment 1, and further improving the user's experience.

[0065] It should be noted that, in actual applications, those skilled in the art may configure the locking member 162 to be connected to the shell 1422 through a threaded connection so as to fix the locking member 162 to the shell 1422, or, may configure the locking member 162 to be connected to the shell 1422 through a fastener so as to fix the locking member 162 to the shell 1422, or, may configure the locking member 162 to be snap-fitted to the shell 1422 so as to fix the locking member 162 to the shell 1422, and so on. Such adjustments and changes to the specific fixing method between the locking member 162 and the shell 1422 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0066] Preferably, the locking member 162 is configured to be connected to the housing 1422 through threads so as to fix the locking member 162 to the housing 1422 .

[0067] Through such a configuration, when the locking member 162 is fixed to the housing 1422 , the operation is simple and the installation is convenient, and the fixing stability between the locking member 162 and the housing 1422 is high, further improving the user experience.

[0068] It should be noted that, in actual applications, those skilled in the art may set an external thread 14221 on the outside of the outer shell 1422, and set an internal thread 1621 on the inside of the locking member 162, and when the locking member 162 is sleeved on the outside of the sealing member 161, a threaded connection between the locking member 162 and the outer shell 1422 is achieved; or, an internal thread may be set on the inside of the outer shell 1422, and an external thread may be set on the outside of the locking member 162, and when the locking member 162 is sleeved on the outside of the sealing member 161, a threaded connection between the locking member 162 and the outer shell 1422 is achieved, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

When the locking member 162 is sleeved on the outside of the sealing member 161, a threaded connection between the locking member 162 and the shell 1422 is achieved.

[0070] By such a configuration, compared with configuring an internal thread inside the outer shell 1422 and configuring an external thread outside the locking member 162, by configuring an external thread 14221 on the outside of the outer shell 1422 and configuring an internal thread 1621 on the inside of the locking member 162, during installation, the open end 1612 of the sealing member 161 can be first placed in the gap 1423 between the outer shell 1422 and the water outlet pipe 1421 to form a pre-fixation, and then the locking member 162 is put on the outside of the sealing member 161, and the internal thread 1621 in the locking member 162 is connected to the external thread 14221 on the outside of the outer shell 1422, thereby making the installation more convenient.

[0071] It should be noted that, in actual applications, the locking member 162 is not limited to being used to lock the sealing member 161 when the drinking water equipment 1 is in the sterilization mode. For example, when the drinking water equipment 1 is in the water extraction mode, the internal thread 1621 of the locking member 162 can also be directly connected to the external thread 14221 on the outer shell 1422 and used as a decorative cover of the outer shell 1422, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0072] Preferably, when the drinking water device 1 is in the water taking mode, the internal thread 1621 in the locking member 162 is connected to the external thread 14221 on the outer shell 1422 , and serves as a decorative cover of the outer shell 1422 .

[0073] Through such a configuration, on the one hand, the external thread 14221 on the outer shell 1422 of the water outlet 142 can be covered to increase the aesthetics of the water outlet 142. On the other hand, the locking component 162 can be prevented from being lost during normal use of the drinking water device, further improving the user experience.

[0074] It should be noted that, in actual application, those skilled in the art can set the locking member 162 to a cylindrical structure with a bottom plugged. When the plugging is completed, the bottom of the locking member 162 abuts against the sealing end 1611 of the sealing member 161. Alternatively, a boss 1613 can be provided on the sealing member 161, and a snap-fitting portion 1622 adapted to the boss 1613 can be provided in the locking member 162. When the plugging is completed, the snap-fitting portion 1622 of the locking member 162 abuts against the sealing end 1611 of the sealing member 161. Alternatively, a connecting member 163 may be provided between the locking member 162 and the sealing member 161. When the sealing is completed, the connecting member 163 abuts against the boss 1613, and the locking portion 1622 abuts against the connecting member 163, that is, the locking member 162 locks the sealing member 161 on the water outlet pipe 1421 through the connecting member 163, and so on. Such flexible adjustment and change does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0075] Preferably, if Figures 3 to 9 As shown, the sealing member 161 includes a sealing end 1611, an open end 1612 and a boss 1613 arranged outside the sealing member 161, and the locking member 162 includes an internal thread 1621 and a clamping portion 1622. When the sealing member 161 blocks the water outlet 142, the open end 1612 of the sealing member 161 is located in the gap 1423 between the housing 1422 and the water outlet pipe 1421, and the sealing end 1611 of the sealing member 161 seals the water outlet pipe 1421. At the same time, the connecting member 163 is also sleeved on the outside of the sealing member 161 and abuts against the boss 1613 (as shown in FIG. Figure 4 As shown in the figure), the locking member 162 is sleeved on the outside of the sealing member 161 and the connecting member 163, so that the locking portion 1622 abuts against the connecting member 163 (not shown in the figure), and the internal thread 1621 of the locking member 162 is connected to the external thread 14221 on the outer shell 1422, so that the sealing member 161 is fixed to the water outlet pipe 1422 through the locking member 162, so that the sealing member 161 can seal the water outlet nozzle 142.

[0076] It should be noted that, in actual applications, those skilled in the art may directly connect the exhaust pipe 15 to the water tank 11, and when the water outlet nozzle 142 is blocked by the sealing component 161, the water in the water outlet chamber 141 flows back into the water tank 11 through the exhaust pipe 15, so that hot water circulates between the water systems; alternatively, a spray assembly may be provided in the water tank 11, and the exhaust pipe 15 is connected to the spray assembly, and when the water outlet nozzle 142 is blocked by the sealing component 161, the water in the water outlet chamber 141 enters the spray assembly through the exhaust pipe 15, and is sprayed toward the inner wall of the water tank 11 under the action of the spray assembly, so that hot water circulates between the water systems, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention, and should be included in the protection scope of the present invention.

[0077] It should also be noted that, in practical applications, those skilled in the art may arrange the exhaust pipe 15 to be connected to a position on the water tank 11 close to the top wall of the water tank 11 (such as Figure 2 As shown), or, the exhaust pipe 15 may be arranged to be connected to a position on the water tank 11 close to the bottom wall of the water tank 11, or, the exhaust pipe 15 may be arranged to be connected to the middle part of the water tank 11, and so on. Such adjustment and change of the connection position of the exhaust pipe 15 and the water tank 11 does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0078] Preferably, the exhaust pipe 15 is arranged to communicate with a position on the water tank 11 close to the bottom wall of the water tank 11 (not shown in the figure).

[0079] Continue reading Figure 1 , and then see Figures 10 to 12 , Fig.10 It is a schematic diagram of the structure of the water tank, exhaust pipe and spray assembly of the present invention; Fig.11 yes Fig. 9 The partially enlarged schematic diagram of the B in the middle shows the schematic diagram when the cover plate closes the water inlet hole; Fig.12 yes Fig. 9 The partially enlarged schematic diagram at B in the figure shows the schematic diagram when the cover plate opens the water inlet hole.

[0080] Preferably, if Figure 1 , Figures 10 to 12 As shown, a spray assembly is provided in the water tank 11, and the spray assembly is connected to the exhaust pipe 15. The spray assembly can spray water flowing from the exhaust pipe 15 toward the top wall and the side wall of the water tank 11, so as to sterilize the top wall and the side wall of the water tank 11.

[0081] Through such a configuration, the water in the water outlet chamber 141 can enter the spray assembly through the exhaust pipe 15, and the water flowing from the exhaust pipe 15 can be sprayed toward the top wall and side walls of the water tank 11 through the spray assembly, so as to sterilize the top wall and side walls of the water tank 11, thereby making the sterilization of the water tank 11 more thorough, preventing the growth of bacteria in the water tank 11 due to the inability to sterilize the top wall and side walls of the water tank 11, avoiding affecting the user's water health, and further improving the user's experience.

[0082] It should be noted that, in actual applications, those skilled in the art may configure the spray assembly to be a booster pump and a spray pipe 113, and transport the water flowing from the exhaust pipe 15 to the spray pipe 113 through the booster pump and spray it onto the top wall and side walls of the water tank 11; or, the spray assembly may be configured to be a water inlet component and a spray pipe 113, and the water flowing from the exhaust pipe 15 may be quickly pushed to the spray pipe 113 through the water inlet component, and sprayed onto the top wall and side walls of the water tank 11 through the spray pipe 113, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0083] Preferably, if Fig.10 As shown, the spray assembly includes a standpipe 111 vertically arranged in the water tank 11, a spray pipe 113 arranged at the top of the standpipe 111, and a water inlet component arranged in the standpipe 111. The bottom end of the standpipe 111 is connected to the exhaust pipe 15, and the top end of the standpipe 111 is connected to the spray pipe 113. The water inlet component is configured to allow water below the water inlet component to enter above the water inlet component. The water inlet component is also configured to be able to quickly push the water located above the water inlet component to the spray pipe 113 so as to spray the water onto the top wall and side walls of the water tank 11.

[0084] Through such an arrangement, on the one hand, it is convenient to let the water entering from the exhaust pipe 15 to the bottom of the water inlet component enter the top of the water inlet component, and quickly push the water above the water inlet component to the spray pipe 113 through the water inlet component to spray the water to the top wall and the side wall of the water tank 11, so as to sterilize the top wall and the side wall of the water tank 11, thereby making the sterilization more thorough; on the other hand, compared with setting the spray assembly in the form of a booster pump and a spray pipe 113, setting the spray assembly as a spray pipe 113, a vertical pipe 111 and a water inlet component arranged in the vertical pipe 111 can greatly reduce the cost of the spray assembly, thereby reducing the cost of the drinking water equipment 1, compared with setting the spray assembly in the form of a booster pump and a spray pipe 113.

[0085] It should be noted that, in actual applications, those skilled in the art may configure the water inlet component to be a water inlet plate 1121 and a water inlet valve disposed on the water inlet plate 1121, and allow the water flowing from the exhaust pipe 15 to enter the upper part of the water inlet plate 1121 through the water inlet valve, and then quickly push the water to the spray pipe 113 through the water inlet plate 1121, or the water inlet component may be configured to be a water inlet plate 1121 and a water inlet hole 1122 and a cover plate 1123 disposed on the water inlet plate 1121 (such as Fig.11 and Fig.12 As shown), when it is necessary to allow water below the water inlet plate 1121 to enter above the water inlet plate 1121, the cover plate 1123 can open the water inlet hole 1122 to allow the water below the water inlet plate 1121 to enter above the water inlet plate 1121; when it is necessary to push the water above the water inlet plate 1121 toward the spray pipe 113, the cover plate 1123 can close the water inlet hole 1122 to prevent the water above the water inlet plate 1121 from flowing to below the water inlet plate 1121 through the water inlet hole 1122, thereby allowing the water inlet plate 1121 to quickly push the water toward the spray pipe 113, and so on. Such adjustments and changes to the specific setting structure of the water inlet component do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0086] Preferably, if Fig.11 and Fig.12 As shown, the water inlet component is a water inlet plate 1121, the edge of the water inlet plate 1121 is sealed and connected to the inner wall of the vertical pipe 111, and the water inlet plate 1121 is provided with a plurality of water inlet holes 1122 and a cover plate 1123 corresponding to the water inlet holes 1122, and the cover plate 1123 is pivotally connected to the water inlet plate 1121 to open / close the water inlet holes 1122.

[0087] By such arrangement, when it is necessary to introduce water below the water inlet plate 1121 to above the water inlet plate 1121, the cover plate 1123 is rotated relative to the water inlet plate 1121 so that the cover plate 1123 and the water inlet plate 1121 form a certain angle (such as Fig.12 As shown), the water below the water inlet plate 1121 enters above the water inlet plate 1121 through the water inlet hole 1122. When the water above the water inlet plate 1121 needs to be pushed into the spray pipe 113, the cover plate 1123 is rotated relative to the water inlet plate 1121 and the cover plate 1123 is parallel to the water inlet plate 1121 to close the water inlet hole 1122 to prevent the water below the water inlet plate 1121 from flowing to the bottom of the water inlet plate 1121 through the water inlet hole 1122, thereby facilitating the rapid pushing of the water above the water inlet plate 1121 into the spray pipe 113, thereby facilitating the sterilization of the inner wall and side walls of the water tank 11.

[0088] It should be noted that, in actual applications, those skilled in the art may set the edge of the water inlet plate 1121 to a material that can undergo elastic deformation, so as to achieve a sealed connection between the edge of the water inlet plate 1121 and the inner wall of the vertical pipe 111, or, a sealing ring may be set between the water inlet plate 1121 and the inner wall of the vertical pipe 111, so as to achieve a sealed connection between the edge of the water inlet plate 1121 and the inner wall of the vertical pipe 111, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0089] Preferably, the edge of the water inlet plate 1121 is made of rubber so that the edge of the water inlet plate 1121 is sealed and connected to the inner wall of the vertical pipe 111 .

[0090] Through such an arrangement, it is convenient to form a seal between the edge of the water inlet plate 1121 and the inner wall of the vertical pipe 111 when the water inlet plate 1121 moves up and down in the vertical pipe 111, preventing the water above the water inlet plate 1121 from flowing out through the gap between the edge of the water inlet plate 1121 and the inner wall of the vertical pipe 111 when the water inlet plate 1121 pushes the water above the water inlet plate 1121 toward the spray pipe 113, thereby avoiding affecting the spraying effect.

[0091] It should be noted that, in practical applications, the cover plate 1123 is not limited to being arranged to be pivotally connected to the water inlet plate 1121. For example, the cover plate 1123 can also be arranged to be slidably connected to the water inlet plate 1121, and the water inlet hole 1122 is opened or closed by sliding the cover plate 1123 relative to the water inlet plate 1121, or the cover plate 1123 can also be arranged to be rotatably connected to the water inlet plate 1121 along a rotation axis perpendicular to the water inlet plate 1121, and the water inlet hole 1122 is opened or closed by rotating the cover plate 1123 relative to the water inlet plate 1121, etc. Such adjustment and change of the specific connection mode between the cover plate 1123 and the water inlet plate 1121 does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention. Of course, preferably, the cover plate 1123 is arranged to be pivotally connected to the water inlet plate 1121.

[0092] It should also be noted that, in actual applications, the water pump 13 of the present invention can work intermittently. When the water pump 13 transports the water in the water outlet chamber 141 to the bottom of the water inlet plate 1121 through the exhaust pipe 15, the water pump 13 stops working. When the water above the water inlet plate 1211 is pushed toward the spray pipe 113, the water pump 13 starts working and when the water in the water outlet chamber 141 is transported to the bottom of the water inlet plate 1211, the water pump 13 stops working again. This reciprocating cycle is used to achieve intermittent operation of the water pump 13.

[0093] It should also be noted that, in actual applications, those skilled in the art may configure the cover plate 1123 to be driven by a motor to rotate the cover plate 1123 relative to the water inlet plate 1121 to open or close the water inlet hole 1122, or may configure the cover plate 1123 to open or close the water inlet hole 1122 through the gravity and pressure of the water itself, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0094] Preferably, the cover plate 1123 is configured to open or close the water inlet hole 1122 by the gravity and pressure of the water itself.

[0095] With such an arrangement, when the water pump 13 delivers hot water to the water outlet chamber 141, due to the blocking of the water outlet nozzle 142, the hot water enters the vertical pipe 111 through the exhaust pipe 15, and under the action of the water pressure below the water inlet plate 1121, the cover plate 1123 rotates relative to the water inlet plate 1121, thereby opening the water inlet hole 1122 (such as Fig.12 As shown), the water below the water inlet plate 1121 enters the upper part of the water inlet plate 1121 through the water inlet hole 1122. When the water above the water inlet plate 1121 is sufficient, the cover plate 1123 is pressed against the upper part of the water inlet plate 1121 by the gravity of the water itself, thereby closing the water inlet hole 1122 (as shown). Fig.11 As shown), the structure is simpler and more energy-saving.

[0096] It should be noted that a negative pressure resistant structure is provided in the exhaust pipe 15. For example, the exhaust pipe 15 can be directly set as a negative pressure resistant hose to resist the negative pressure formed under the water inlet plate 1121 when the water inlet plate 1121 pushes the water above the water inlet plate 1121 toward the spray pipe 113. Alternatively, a negative pressure deformation chamber can be provided in the exhaust pipe 15 to resist the negative pressure formed under the water inlet plate 1121 when the water inlet plate 1121 pushes the water above the water inlet plate 1121 toward the spray pipe 113.

[0097] Preferably, the exhaust pipe 15 is configured as a negative pressure-resistant hose.

[0098] It should be noted that, in actual applications, those skilled in the art may provide a lifting handle on the water inlet component. During the sterilization process of the drinking water equipment 1, the user may pull the lifting handle as needed to make the water inlet component move up and down in the vertical direction in the vertical pipe 111. Alternatively, a driving component 114 may be provided, and the output end of the driving component 114 is fixedly connected to the water inlet component. During the sterilization process of the drinking water equipment 1, the driving component 114 automatically drives the water inlet component to move up and down in the vertical direction in the vertical pipe 111, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention, and should be included in the protection scope of the present invention.

[0099] Preferably, if Fig.10 As shown, the spray assembly further includes a driving component 114 , which can drive the water inlet component to move up and down in the vertical direction in the vertical pipe 111 .

[0100] Through such an arrangement, when the driving component 114 drives the water inlet component to move downward in the vertical pipe 111, the water below the water inlet plate 1121 can enter above the water inlet plate 1121; when the driving component 114 drives the water inlet component to move upward in the vertical pipe 111, the water above the water inlet plate 1121 can be quickly pushed into the spray pipe 113, thereby facilitating the sterilization of the top wall and side walls of the box body 11; at the same time, the driving component 114 can automatically drive the water inlet component to move up and down in the vertical direction in the vertical pipe 11 without the need for manual operation by the user, thereby facilitating the automatic sterilization of the top wall and side walls of the water tank 11, making the sterilization of the drinking water equipment 1 more intelligent.

[0101] It should be noted that, in actual applications, those skilled in the art may arrange the driving component 114 above the water inlet plate 1121, and the output end of the driving component 114 is fixedly connected to the top of the water inlet plate 1121, or the driving component 114 may be arranged below the water inlet plate 1121, and the output end of the driving component 114 is fixedly connected to the bottom of the water inlet plate 1121, and so on. Such adjustments and changes to the specific setting position of the driving component 114 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0102] Preferably, if Fig.10 As shown, the driving component 114 is disposed above the water inlet plate 1121 , and the output end of the driving component 114 is fixedly connected to the top of the water inlet plate 1121 .

[0103] Through such a configuration, compared with configuring the driving component 114 below the water inlet plate 1121 , configuring the driving component 114 above the water inlet plate 1121 can make the installation of the driving component 114 more convenient without having to consider the sealing problem between the driving component 114 and the bottom of the vertical pipe 111 .

[0104] It should be noted that, in actual applications, those skilled in the art may configure the driving component 114 to be driven by a motor to rotate the gear, and the gear drives the rack to move up and down in the vertical direction, thereby driving the water inlet plate 1121 to move up and down in the vertical direction, or, the driving component 114 may be configured to be driven by a cylinder to move the water inlet plate 1121 up and down in the vertical direction, and so on. Such adjustments and changes to the specific setting types of the driving component 114 do not deviate from the principles and scope of the present invention, and should be included in the protection scope of the present invention.

[0105] Preferably, the driving member 114 is configured as a cylinder, and the output end of the cylinder is fixedly connected to the top end of the water inlet plate 1121 to drive the water inlet plate 1121 to move up and down in the vertical direction.

[0106] Through such an arrangement, the structure of the driving component 114 can be made simpler and the installation more convenient.

[0107] It should be noted that, in actual applications, those skilled in the art may configure the spray pipe 113 to be a pipe with multiple spray holes 1131, or may configure the spray pipe 113 to be a pipe with multiple branches and spray heads arranged on the multiple branches, etc. Such adjustments and changes to the specific setting type of the spray pipe 113 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0108] Preferably, if Fig.10 As shown, the spray pipe 113 is configured as a pipe with multiple spray holes 1131. When the water inlet plate 1121 quickly pushes the water above the water inlet plate 1121 to the spray pipe 113, the water is sprayed toward the top wall and side walls of the water tank 11 through the multiple spray holes 1131 provided on the spray pipe 113, thereby sterilizing the top wall and side walls of the water tank 11, making the sterilization of the water system more thorough.

[0109] It should be noted that, in actual applications, those skilled in the art may set the spray pipe 113 in the middle of the water tank 11, or, may set the spray pipe 113 at a position close to the top wall of the water tank 11, and so on. Such adjustments and changes to the specific setting position of the spray pipe 113 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0110] Preferably, if Fig.10 As shown, the spray pipe 113 is arranged close to the top wall of the water tank 11.

[0111] Through such an arrangement, the water in the spray pipe 113 can be more easily sprayed toward the top wall and the side wall of the water tank 11 through the spray hole 1131, so as to better sterilize the top wall and the side wall of the water tank 11 and make the sterilization more thorough.

[0112] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle 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 these changes or substitutions will fall within the protection scope of the present invention.
