[0050] like Figure 1 As shown, the drinking water equipment includes a housing, a pure water tank assembly 10 and a water outlet structure 40. The pure water tank assembly 10 includes a first pure water tank 11 and a second pure water tank 12 which can be interconnected. The first pure water tank 11 is arranged in the housing. The first pure water tank 11 includes a pure water inlet 111 and a pure water outlet 112. The pure water inlet 111 is used to pass pure water. The second pure water tank 12 is detachably arranged in the housing. The second pure water tank 12 includes a box body 121 and a heating assembly 122 arranged in the box body 121. The box body 121 is provided with a water outlet. The pure water outlet 112 can be communicated with the water outlet to pass pure water into the box body 121 through the first pure water tank 11. The heating assembly 122 is configured to be connected to a power supply after the second pure water tank 12 is removed from the housing. The water outlet structure 40 is connected to the housing. The water outlet structure 40 can selectively communicate with the first pure water tank 11 and / or the second pure water tank 12.

[0051] After pure water enters the first pure water tank 11, the pure water entering the first pure water tank 11 can enter the second pure water tank 12 through the pure water outlet 112 and the water outlet in turn, so that the purified pure water is stored in the first pure water tank 11 and the second pure water tank 12. The first pure water tank 11 and the second pure water tank 12 can both store pure water in advance, which can increase the pure water storage space of the drinking water equipment, thereby meeting the user's large water demand.

[0052] The second pure water tank 12 is detachably connected to the casing, and the second pure water tank 12 can be removed and used as needed to quickly obtain a large amount of pure water, shorten the user's waiting time, and improve the user's experience.

[0053] The second pure water tank 12 includes a box body 121 and a heating component 122 connected to the box body 121. The heating component 122 can be powered on and used after the second pure water tank 12 is removed from the casing to heat the pure water in the box body 121 to meet the user's needs for warm water or hot water, thereby improving the user's experience.

[0054] In order to facilitate the use of the heating component 122 after the second pure water tank 12 is removed from the casing, the heating component 122 includes a docking port, which can be a power socket for connecting a power cord to power the heating component 122 to heat the water in the tank body 121.

[0055] It should be noted here that the power socket is a common structure in the prior art. The specific structure of the power socket and the connection method with the power cord can adopt any structure and connection method in the prior art, as long as the power supply can be connected through the power cord to power the heating component 122, it will not be described in detail in this embodiment.

[0056] In some embodiments, the second pure water tank 12 can be matched with the charging stand after being removed from the housing. The charging stand includes a power cord to connect to a power source to power the heating component 122, so that the second pure water tank 12 can be used as an electric kettle or a teapot after being removed. It should be noted here that the docking port and the charging stand are common structures in the prior art. The specific structure and matching method of the docking port and the charging stand can adopt any structure and matching method in the prior art, as long as they can power the heating component 122, and will not be specifically introduced in this embodiment.

[0057] In some embodiments, the heating assembly 122 includes a battery and a heating element, the battery is electrically connected to the heating element, and the battery is used to power the heating element to heat the water in the box 121. The battery can be replaced, or the battery is a rechargeable battery for repeated use.

[0058] Optionally, the heating component 122 further includes a base, the base is provided with a battery slot, the battery is detachably arranged in the battery slot, and the battery can be electrically connected to the heating element.

[0059] In this embodiment, the heating assembly 122 includes a heating element, which is a heating tube. The heating tube can be spirally coiled on the bottom of the box 121 to increase the effective heating area of ​​the box 121 and heat the pure water in the box 121 more evenly.

[0060] In some embodiments, the heating component 122 also includes a seat, and the heating element is arranged in the seat. The seat and the box 121 are detachably connected to facilitate replacement of the box 121 or the heating component 122 separately, thereby reducing maintenance costs and providing more flexible user operation.

[0061] In this embodiment, the second pure water tank 12 is arranged outside the housing. That is to say, the first pure water tank 11 is a built-in pure water tank, and the second pure water tank 12 is an external pure water tank, which is detachably connected to the housing, so that the user can remove the second pure water tank 12 for use as needed, which is easy to operate.

[0062] In other embodiments, at least two first pure water tanks 11 can be provided inside the casing to increase the pure water storage capacity, and at least two first pure water tanks 11 can be connected in sequence; at least two second pure water tanks 12 outside the casing can be provided to increase the pure water storage capacity, and the user can choose to remove one or more second pure water tanks 12 for use according to the amount of water used.

[0063] In some embodiments, the housing may include a housing and a cover body movably connected or detachably connected to the housing, the housing is provided with a take-in / take-out port, the cover body is used to cover the take-in / take-out port, and the second pure water tank 12 is provided in the housing and can be installed into the housing through the take-in / take-out port or removed from the housing through the take-in / take-out port. Although the second pure water tank 12 is located in the housing, by providing the take-in / take-out port and the cover body, it is convenient for the user to install or remove the second pure water tank 12 from the take-in / take-out port, and the operation is convenient.

[0064] Optionally, the cover body and the shell body can be rotatably or slidably connected to open or close the access port as needed; or, the cover body can be detachably connected to the shell body by fasteners such as snap-fit ​​or screws to facilitate the installation or removal of the second pure water tank 12 after removing the cover body.

[0065] In order to ensure that pure water can enter the second pure water tank 12 through the first pure water tank 11, the first pure water tank 11 and the box body 121 can be connected to form a communicating vessel. Specifically, the first pure water tank 11 and the second pure water tank 12 are both connected to the atmosphere, and the two are connected to form a communicating vessel. The water level of the pure water in the first pure water tank 11 is flush with the water level of the pure water in the second pure water tank 12, so that pure water can enter the second pure water tank 12 through the first pure water tank 11. It is not necessary for the first pure water tank 11 and the second pure water tank 12 to be connected to the pure water source respectively, which is conducive to simplifying the pipeline.

[0066] Specifically, the pure water outlet 112 is arranged on the bottom surface of the first pure water tank 11 , and the water inlet is arranged at the bottom of the box body 121 , so that the pure water in the first pure water tank 11 can smoothly enter the box body 121 .

[0067] In addition, the water outlet is the inlet and outlet of the pure water in the box 121. Setting the water outlet on the bottom surface of the box 121 also facilitates the smooth discharge of the pure water in the box 121, thereby improving the drainage effect of the pure water in the box 121 to avoid pure water always remaining in the box 121 and causing pollution such as bacterial growth.

[0068] In order to allow the box 121 to be filled with pure water under the water supply of the first pure water tank 11 or to ensure that the box 121 can store pure water of a certain liquid level, the bottom height of the box 121 is not higher than the bottom height of the first pure water tank 11. In other words, the lowest water level in the box 121 is flush with the lowest water level in the first pure water tank 11, or lower than the lowest water level in the first pure water tank 11, so that the pure water source supplies pure water to the box 121 first.

[0069] Optionally, the inner top surface of the first pure water tank 11 is not lower than the inner top surface of the box body 121. In other words, the highest water level of pure water that can be contained in the first pure water tank 11 is not lower than the highest water level of pure water that can be contained in the box body 121, so as to ensure that before the box body 121 is fully loaded, the first pure water tank 11 still has space to hold pure water, so as to ensure that the volume in the box body 121 can be fully utilized.

[0070] like Figure 1 As shown, the pure water tank assembly 10 also includes a first pipeline 13 and a second pipeline 14. One end of the first pipeline 13 is connected to the pure water outlet 112, and the other end can be connected to the water outlet structure 40; one end of the second pipeline 14 can be detachably connected to the box body 121 so as to be connected to the water outlet, and the other end is connected to the first pipeline 13, so as to ensure that the first pure water tank 11 and the box body 121 can be connected to the water outlet structure 40 on the basis that the first pure water tank 11 and the box body 121 can be connected, so that the pure water in the first pure water tank 11 or the box body 121 can be selectively used.

[0071] For the convenience of introduction, the connecting position between the second pipeline 14 and the first pipeline 13 divides the first pipeline 13 into two sections, namely a water supply section located upstream of the connecting position and a water outlet section located downstream of the connecting position. The pure water in the first pure water tank 11 can enter the second pipeline 14 through the water supply section, and then enter the box body 121 through the water outlet; the pure water in the first pure water tank 11 and / or the pure water in the box body 121 can enter the water outlet structure 40 through the water outlet section for user use.

[0072] In order to control the on-off of the first pipeline 13 and the second pipeline 14, the pure water tank assembly 10 further includes a valve assembly, which is used to control the on-off of the water supply section and the second pipeline 14. In this embodiment, the valve assembly includes a first switch valve 15 and a second switch valve 16, the first switch valve 15 is arranged on the first pipeline 13, and is located upstream of the connection position of the first pipeline 13 and the second pipeline 14, that is, the first switch valve 15 is arranged on the water supply section; the second switch valve 16 is arranged on the second pipeline 14.

[0073] When the pure water source supplies pure water to the first pure water tank 11 and the second pure water tank 12, the first switch valve 15 and the second switch valve 16 are both opened, and the pure water provided by the pure water source passes through the first pure water tank 11, the pure water outlet 112 and the water outlet and enters the tank body 121, and the water level in the tank body 121 gradually rises, and the water level in the first pure water tank 11 is always flush with the water level in the tank body 121; when the tank body 121 is full of pure water or the water level in the tank body 121 reaches the highest liquid level, the second switch valve 16 and the first switch valve 15 are closed, the first pure water tank 11 is not connected to the tank body 121, and the pure water source continues to supply pure water to the first pure water tank 11, so that the water level in the first pure water tank 11 continues to rise.

[0074] In some embodiments, the valve assembly includes a switching valve, the switching valve includes a first valve port, a second valve port and a third valve port, the first valve port is connected to the pure water outlet 112, the second valve port is connected to the water outlet, and the third valve port is connected to the water outlet structure 40. The switching valve can switch the connection state so that the first valve port and the second valve port are connected, or one of the first valve port and the second valve port is connected to the third valve port. Optionally, the switching valve is a three-way valve.

[0075] In order to facilitate the detection of the water levels in the first pure water tank 11 and the box body 121, water level detection components are provided in the first pure water tank 11 and the box body 121. For the convenience of introduction, the water level detection component in the first pure water tank 11 is the first water level detection component 113, the first pure water tank 11 is provided with a first preset high liquid level and a first preset low liquid level, and the first water level detection component 113 can be triggered when the water level in the first pure water tank 11 reaches the first preset high liquid level and the first preset low liquid level; the water level detection component in the box body 121 is the second water level detection component 123, the box body 121 is provided with a second preset high liquid level and a second preset low liquid level, and the second water level detection component 123 can be triggered when the water level in the box body 121 reaches the second preset high liquid level and the second preset low liquid level.

[0076] The water level detection member may be a float water level detection member, including a guide rod, a float and two float sensors. The guide rod extends vertically, the float is slidably arranged on the guide rod, and the two float sensors are arranged in the vertical direction, roughly flush with the heights of the preset high liquid level and the preset low liquid level, respectively. The float sensor can be arranged on the guide rod or on the side of the guide rod. The float is located between the two float sensors and moves with the change of water level. When the water level drops to the preset low liquid level, the float triggers the float sensor below; when the water level rises to the preset high liquid level, the float triggers the float sensor above. Among them, the float can trigger the float sensor by contact.

[0077] In other embodiments, the water level detection component may be an ultrasonic water level meter, an electronic water gauge, or a pressure water level meter, as long as it can detect water level changes.

[0078] Optionally, the second water level detection member 123 can be electrically connected to the valve assembly. When the second water level detection member 123 detects that the water level in the box body 121 drops to a second preset low liquid level, the first switch valve 15 and the second switch valve 16 are opened, and the pure water source replenishes pure water into the box body 121 through the first pure water tank 11; when the second water level detection member 123 detects that the water level in the box body 121 rises to a second preset high liquid level, the second switch valve 16 is closed, and the first pure water tank 11 stops supplying water into the box body 121 to prevent the pure water in the box body 121 from overflowing.

[0079] Optionally, the first water level detection component 113 can be electrically connected to the valve assembly so as to control the on-off of the water supply section and the second pipeline 14 according to the water level change in the first pure water tank 11, so as to adjust the water supply from the first pure water tank 11 to the water outlet structure 40, or from the box body 121 to the water outlet structure 40 according to actual conditions.

[0080] In order to prevent pure water from overflowing through the second pipeline 14 after the second pure water tank 12 is removed from the housing, the housing is provided with a trigger, which is configured to be triggered when the second pure water tank 12 is installed in the housing, and the trigger is electrically connected to the valve assembly, which is configured to shut off the second pipeline 14 after the second pure water tank 12 is removed from the housing. Through the cooperation of the trigger and the valve assembly, it can be ensured that the second pipeline 14 is in a shut-off state after the second pure water tank 12 is removed, so as to prevent pure water from overflowing from the second pipeline 14.

[0081] It should be noted here that the second pure water tank 12 also includes an on-off valve placed in the water outlet. The on-off valve can be in an open state when the second pure water tank 12 is installed in the casing, and can be in a closed state after the second pure water tank 12 is removed from the casing to avoid water leakage after the second pure water tank 12 is removed.

[0082] Optionally, the on-off valve includes an elastic member and a valve stem, a blocking portion is provided on the valve stem, the elastic member connects the valve stem and the housing 121, and the elastic member is used to drive the valve stem to move so that the blocking portion cooperates with the water outlet to achieve the purpose of blocking the water outlet. When the second pure water tank 12 is installed on the housing, an abutment portion is provided on the housing, and the abutment portion can abut and push the valve stem to overcome the elastic force of the elastic member, so that the valve stem drives the blocking portion to move in the direction of opening the water outlet.

[0083] Optionally, a plugging portion is formed at the top of the valve stem, and the radial dimension of the plugging portion is larger than the radial dimension of the valve stem and equal to or larger than the radial dimension of the water outlet, so that the plugging portion can block the water outlet. The plugging portion can be made of elastic material to improve the plugging effect.

[0084] like Figure 1 As shown, a flow meter 17 is provided on the first pipeline 13, and the flow meter 17 can calculate the flow rate of pure water flowing through the first pipeline 13. Optionally, the flow meter 17 can be provided at the water outlet section of the first pipeline 13 to detect the flow rate of pure water flowing to the water outlet structure 40.

[0085] Optionally, a disinfection component 18 may be further provided on the first pipeline 13, and the disinfection component 18 may disinfect the pure water passing through the first pipeline 13 to ensure drinking hygiene.

[0086] Optionally, the disinfection assembly 18 can be arranged on the water outlet section or on the water supply section. When the disinfection assembly 18 is arranged on the water outlet section, the pure water in the first pure water tank 11 and the box body 121 can be disinfected when passing through the disinfection assembly 18 to ensure the hygiene of drinking water; when the disinfection assembly 18 is arranged on the water supply section, the pure water flowing from the first pure water tank 11 to the box body 121 or to the water outlet structure 40 can be disinfected, which is conducive to ensuring the hygiene of drinking water.

[0087] Optionally, the disinfection assembly 18 may include a UV disinfection lamp to disinfect the pure water by ultraviolet rays.

[0088] Optionally, the UV disinfection lamp can be a flow-through UV disinfection lamp.

[0089] Optionally, the water outlet section of the first pipeline 13 may be provided with a water pump 60, which can drive the pure water in the pure water tank assembly 10 to flow toward the water outlet structure 40 to ensure the water supply flow rate and flow rate.
