[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1 Please see Figure 1 , Figure 2 and Figure 3 This utility model is a smart water cup with a built-in filter, including a cup body 100, a cup lid 200 and a straw-type filter mechanism 300. The cup lid 200 is detachably connected to the top of the cup body 100. The cup body 100 and the cup lid 200 are connected by a snap or a thread. The straw-type filter mechanism 300 is detachably connected to the center of the cup lid 200. The straw-type filter mechanism 300 includes a filter part, a sterilization part, a heating part and a protective part.

[0030] Specifically, a control box 210 is embedded on one side of the top of the cup lid 200. A switch button is installed on the top surface of the control box 210, a USB connection port is installed on the side of the control box 210, a control motherboard module is fixed inside the control box 210, a lithium battery is fixed inside the control box 210, and a temperature sensor is fixed on the bottom of the cup body 100. The temperature sensor is wirelessly connected to the control motherboard module inside the control box 210.

[0031] Furthermore, a USB cable 321 is connected to the straw nozzle 320. The USB cable 321 of the straw-type filter mechanism 300 is plugged into the USB port of the control box 210. The lithium battery in the control box 210 powers the straw-type filter mechanism 300. In addition, the USB port of the control box 210 can also be used for charging.

[0032] The operation process of this embodiment is as follows: When the user needs to use this smart water cup, first turn it upward or push the opening buckle to remove the cup lid 200 from the top of the cup body 100. At this time, the straw-type filter mechanism 300 is lifted together with the cup lid 200. Then, inject the water source to be treated (such as tap water, wild water source, etc.) into the cup body 100. When injecting water, pay attention to the water volume not exceeding the maximum scale line on the inner wall of the cup body 100. Then, put the cup lid 200 together with the straw-type filter mechanism 300 back on the top of the cup body 100 and tighten the cup lid 200. After the cup lid 200 is closed, the control motherboard module of the smart water cup can be activated by the switch button on the top of the control box 210. The control motherboard module is powered by the built-in lithium battery and receives temperature data wirelessly transmitted from the temperature sensor at the bottom of the cup body 100. When heating or sterilization is required, users can select the appropriate working mode through the button and control the main board module to start and stop the relevant components according to the preset program for water temperature monitoring, water temperature regulation and water sterilization. In addition, the straw-type filter mechanism 300 adopts a modular quick-release design. Its replacement operation is as follows: First, the user unplugs the USB connection cable 321 connecting the straw nozzle 320 from the USB interface on the side of the control box 210 to disconnect the power and signal path. Then, the entire straw-type filter mechanism 300 is vertically removed from the center of the cup lid 200 by rotating it. During installation, first insert the new straw-type filter mechanism 300 into the cup lid 200 and tighten it to lock it. Then, insert the USB connection cable 321 to restore the electrical connection. At this time, the control motherboard module will automatically recognize and connect the new straw-type filter mechanism 300.

[0033] Example 2 Please see Figure 2 , Figure 3 and Figure 4Based on Embodiment 1, the filtration section includes a straw nozzle 320 and a filter tube 330 that are connected from top to bottom, and the sterilization section includes a set of ultraviolet lamps 350 surrounding the outside of the filter tube 330. The straw nozzle 320 is fixed to the top of the center of the top plate 310, and the filter tube 330 is fixed to the bottom of the center of the top plate 310; the bottom of a set of ultraviolet lamps 350 is fixed to the top surface of the base plate 340, and the top of a set of ultraviolet lamps 350 is fixed to the bottom surface of the top plate 310.

[0034] Specifically, the filter tube 330 has multiple filtration layers inside, which are set from bottom to top as a PP cotton layer, a composite activated carbon layer and an ultrafiltration membrane layer (water exits after passing through the PP cotton layer, the composite activated carbon layer and the ultrafiltration membrane layer in sequence).

[0035] Furthermore, the straw nozzle 320 and the filter tube 330 are internally connected. The upper and lower halves of the straw nozzle 320 are both provided with threaded slots. The upper half of the straw nozzle 320 is threadedly connected to the tube cap 322, and the lower half of the straw nozzle 320 is threadedly connected to the connecting cylinder in the center of the top plate 310.

[0036] The operation process of this embodiment is as follows: when the user drinks water through the straw nozzle 320, water enters the straw nozzle 320 from the cup body 100 and then flows into the filter tube 330; The water undergoes the following purification process as it passes through filter tube 330: First, large particles of impurities are filtered out through the PP cotton layer. Then, the mixture flows through the composite activated carbon layer to adsorb odors, residual chlorine, and organic matter. Finally, bacteria, microorganisms, and even smaller suspended matter are filtered out through the ultrafiltration membrane layer, thereby achieving deep purification. During breaks in drinking water, the ultraviolet lamp 350 can be activated via the control box 210. The ultraviolet lamp 350 emits ultraviolet light around the outside of the filter tube 330, continuously or intermittently irradiating and sterilizing the surface of the filter tube 330 and the surrounding water to prevent bacterial growth and maintain the hygiene and safety of drinking water.

[0037] Example 3 Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 Based on Embodiments 1 and 2, the heating part includes a heating tube 380, the protective part includes a protective cover assembly 360 that is movably covered outside the filter tube 330 and the ultraviolet lamp tube 350, and a driving assembly 370 for driving the protective cover assembly 360, and the opening and closing of the protective cover assembly 360 is driven by the driving assembly 370. The drive assembly 370 is fixed to the inner bottom of the cup lid 200, and the heating tube 380 is fixed to the bottom of the base plate 340; The protective cover assembly 360 includes an inner protective cover 361 and an outer protective cover 362, with the outer protective cover 362 fitted over the outer side of the inner protective cover 361. The protective cover assembly 360 is made of heat-insulating material.

[0038] Specifically, the top surface of the inner cover 361 is fixed to the bottom of the top plate 310, and the bottom surface of the inner cover 361 is fixed to the top of the base plate 340. The bottom surface of the top plate 310 and the top surface of the base plate 340 are both provided with symmetrically arranged annular grooves. The top of the outer cover 362 is slidably connected to the annular groove on the bottom surface of the top plate 310, and the bottom of the inner cover 361 is slidably connected to the annular groove on the top surface of the base plate 340. The drive assembly 370 includes a waterproof motor 371 and a gear 372. The housing of the waterproof motor 371 is fixed to the bottom of the cup lid 200. The output shaft of the waterproof motor 371 passes through the housing and is connected to the gear 372. The waterproof motor 371 is wirelessly connected to the control main board module in the control box 210.

[0039] Furthermore, the inner cover 361 has a set of annularly distributed inner door grooves, and the outer cover 362 has a set of annularly distributed outer door grooves. The size of the inner door grooves is smaller than that of the outer door grooves. A set of arc-shaped teeth 3601 is fixed on the top side of the outer cover 362, and the gear 372 meshes with the teeth 3601.

[0040] The operation process of this embodiment is as follows: when not drinking or during heating, the protective cover assembly 360 is in a completely closed state, which protects the filter tube 330 and the ultraviolet lamp tube 350. When using the heating function, first remove the cup lid 200 and the straw-type filter mechanism 300 as a whole, then press the switch button on the control box 210. The control main board module first starts the drive component 370, and the waterproof motor 371 drives the gear 372 to rotate. The gear 372 meshes with the teeth 3601 on the top of the outer cover 362, driving the outer cover 362 to rotate relative to the outer surface of the inner cover 361. During the rotation, the inner door groove on the inner cover 361 and the outer door groove on the outer cover 362 are completely misaligned, so that the cover assembly 360 forms a completely closed cylindrical structure, completely protecting the filter tube 330 and the ultraviolet lamp tube 350 inside. Then, the straw-type filter mechanism 300 is placed into the cup body 100 and the cup lid 200 is tightened. At this time, the protective cover assembly 360 plays a role in heat insulation and protection, preventing the high temperature during heating from affecting the structure and performance of the filter section and the sterilization section. Next, press the switch button on the control box 210 to start the heating element 380. The heating element 380 will heat the water in the cup to boiling. After the water boils, the temperature sensor inside the cup body 100 continuously monitors the water temperature. Once the water temperature drops to a safe drinking temperature (such as below 50℃), the control motherboard module restarts the drive component 370, driving the outer cover 362 to rotate in the opposite direction, so that the inner door groove on the inner cover 361 and the outer door groove on the outer cover 362 gradually overlap, opening the channel. After the channel is opened, the user can drink the warm water in the cup through the straw 320. Before the water enters the straw 320, it will first flow through the channel opened by the protective cover assembly 360 and come into contact with the filter tube 330 to achieve final filtration before drinking. During or after drinking, the user can choose to turn on the ultraviolet lamp 350 again for sterilization.
