Description

Technical Field

[0001] This invention relates to the field of water treatment, and more specifically, to an intelligent ultraviolet sterilization filter straw cup. Background Technology

[0002] Viruses and bacteria are almost ubiquitous in our daily lives, even in tap water systems. Water that appears clear on the surface may already be contaminated. This contamination can include toxic pathogens such as amoeba dysentery, typhoid fever, schistosomiasis, liver leeches, and cholera, as well as decaying plant stems and leaves, insect carcasses, bird carcasses, animal feces, and many other contaminants that are invisible to the naked eye. Direct consumption of such contaminants can cause diarrhea, colds, fever, and other discomfort. Therefore, to ensure safe and healthy access to drinking water, more effective disinfection tools are needed.

Detailed Implementation

[0041] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0042] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0044] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] Example 1

[0047] like Figures 1 to 8 As shown, this invention provides an intelligent ultraviolet sterilization and filtering straw cup, comprising: a cup body 1, a cup lid 2 connected to the cup body, a straw 3 connected to the cup lid 2, and a filtering device 4 connected to the straw 3. The filtering device 4 is located inside the cup body 1 and connected to the straw 3 of the cup lid 2. Water in the cup body 1 must pass through the filtering device 4 before being drawn out through the straw 3.

[0048] The cup body 1 is provided with a cup mouth 11, which is connected to the cup lid 2. Optionally, the cup lid 2 is threadedly connected to the cup mouth 11 of the cup body 1 for easy disassembly and cleaning.

[0049] The cup lid 2 includes a cup lid shell 21, a screw cap 22, and a photoelectric component 23. A panel 211 is mounted on the cup lid shell 21. A spout slot 217 is provided on the upper part of the cup lid shell 21. A spout 212 and a waterproof silicone spout 213 are installed in the spout slot 217. Limiting posts 2121, which fit the grooves on the inner wall of the spout slot 217, are provided on both sides of the spout 212. A first hole post 215 is provided at the lower part of the cup lid shell 21. A through hole 2151 is provided in the middle of the first hole post 215. A waterproof ring 215 for the straw hole is fitted into the base of the first hole post 215. A limiting protrusion 2123 is provided on the upper part of the spout 212. A through hole 2122 is provided in the middle of the spout 212. When the spout 212 is fully open, the spout 212 communicates with the first hole post 215. Figure 7 The image shows the state when the suction nozzle 212 is fully closed; as shown... Figure 8 The image shows the state when the suction nozzle 212 is fully open.

[0050] It should be noted that this structure not only allows for safe and healthy drinking water without opening the lid, avoiding secondary contamination from opening the lid, but also features a rotating, concealed spout design. Figure 7 and Figure 8 As shown, when the spout 212 is open or closed, the waterproof silicone 213 of the spout provides a seal, preventing liquid from leaking out of the lid 2. When the spout 212 is closed, it fits tightly into the spout slot 217. Rotating the spout 2121 via the limiting post 2121 allows for both drinking when open and sealing when closed. Additionally, the lid 2 can be inverted when pouring water to prevent contamination of the straw.

[0051] The screw cap 22 is installed inside the cup lid shell 21 through a sealing element. The screw cap 22 is also provided with a receiving cavity, a second post 221 and an upper end face 222. The second post 221 is set in the receiving cavity. A light passage hole is provided on the bottom surface of the receiving cavity. An air inlet waterproof silicone 214 is installed on the second post 221. The receiving cavity and the upper end face 222 are provided with mounting holes for installing the photoelectric component 23. The photoelectric component 23 is placed in the receiving cavity.

[0052] Optoelectronic component 23 includes a light source component and an electronic control component.

[0053] The light source assembly includes a metal ring 231, a lens 232, a first waterproof ring 233, a gasket 234, and a sterilization device. The metal ring 231 is placed close to the light outlet hole, and the first waterproof ring 233 is placed close to the metal ring 231. The lens 232, which is made of quartz glass, is embedded in the groove of the first waterproof ring 233. The gasket 234 is placed close to the first waterproof ring 233. The sterilization device is placed on the gasket 234 and is a light source plate 235 equipped with an ultraviolet light-emitting diode. The ultraviolet light-emitting diode faces the inner cavity of the cup body 1. The ultraviolet light-emitting diode is coaxially mounted with the metal ring 231, the lens 232, the first waterproof ring 233, the gasket 234, and the light outlet hole. The light source plate 235 is mounted on the mounting hole of the screw cap 22 receiving cavity.

[0054] It should be noted that the light source assembly is the core component of the device. The ultraviolet rays emitted through the light source plate 235 can penetrate the translucent quartz glass and directly act on the water. Ultraviolet light is used because of its powerful sterilization function, long lifespan, low energy consumption, high power output, cold light source, uniform irradiation, and maintenance-free operation. It can eliminate more than 50 kinds of bacteria, mold, and viruses in a short time, with a sterilization effect of up to 99.9999%. The metal ring 231, the first waterproof ring 233, and the gasket 234 are tightly fitted together to isolate the inside of the cover from water, achieving a waterproof effect. At the same time, the gasket is slightly higher than the LED beads, leaving a gap between the LED beads and the quartz glass to ensure that the quartz glass is not crushed during assembly.

[0055] The electronic control assembly includes a battery 236 and a drive board 237. The battery 236 is placed on the light source board 235, and the drive board 237 is placed above the battery 236. The drive board 237 is installed in the mounting hole on the upper end face 222 of the screw cover 22. The sterilization device is driven by an integrated circuit chip on the drive board 237. The integrated circuit chip is electrically connected to an ultraviolet light-emitting diode (not shown in the figure), a sterilization control switch 220, a sterilization working indicator light 219, and a conductor sensing device composed of a capacitive sensing chip and a sensing sheet 238 electrically connected to the capacitive sensing chip. The sensing sheet 238 is vertically mounted on the drive board 237. The drive board 237 is also provided with a magnetic charging base 218 and a charging indicator light 217 electrically connected to the integrated circuit chip.

[0056] It should be noted that the circuit schematic of the circuit chip set on the driver board 237 is as follows: Figure 9 As shown: The circuit chip of this invention uses the HC18P110 microcontroller as the control chip for the entire product.

[0057] Pin 3 of the microcontroller is connected to N-channel transistor Q2, controlling P-channel MOSFET Q1, which in turn controls the power supply to the HX7173 ultraviolet LED driver chip. During touch operation, pin 3 of the microcontroller outputs a high level, MOSFET Q1 conducts, connecting the battery to the driver chip, and the driver begins to power the ultraviolet LED. MOSFET Q1 is connected to HX4054 charging management chip U1 for constant current charging of the battery, preventing damage from high-current charging. It connects to an external charger via the CON2 interface. Simultaneously, FC1821 battery charging management chip U2 is connected in parallel to protect the battery from overcharging and over-discharging. When the battery voltage drops below 2.9V, the battery charging management chip directly shuts off the battery's output to prevent over-discharge. If a short circuit occurs in the battery management chip's back-end circuit, it will also automatically shut off the output to prevent the circuit board from catching fire.

[0058] Pin 6 of the microcontroller is connected to the N-channel transistor Q4, which controls the P-channel MOSFET Q3 to power four RGB tri-color LEDs. The tri-color LEDs display a blue breathing state when sterilization is in progress and an orange breathing state when charging.

[0059] The microcontroller's pin 8 is connected to the touch chip HX813. When a touch action occurs on the touch chip's pin 3, the touch chip's pin 1 changes from high level to low level, and the cup begins to sterilize.

[0060] Pin 13 of the microcontroller is the AD battery power detection pin. It samples the battery voltage through resistors R12 and R13 to monitor the battery voltage and remind the user of the battery status. The linear step-down chip U3, model 6213-SOT23, reduces the battery voltage to 3V to power the microcontroller, ensuring that the microcontroller's various reference voltages remain constant and are not affected by changes in battery voltage.

[0061] Pin 14 of the microcontroller is grounded.

[0062] To completely eliminate the risk of ultraviolet leakage, this embodiment uses a capacitive sensing chip drive circuit control method, adding a conductor sensing device. When the cup lid is screwed into the cup body, the sensing chip detects the metal cup mouth, and the chip turns on the ultraviolet light-emitting diode control switch to light up the sterilization light source for sterilization and disinfection. When the cup lid is screwed out of the cup body, the sensing chip cannot detect the conductor, the ultraviolet light-emitting diode control switch cannot be turned on normally, and the sterilization light source cannot be lit, thereby preventing damage caused by ultraviolet leakage.

[0063] One end of the straw 3 is connected to the first perforated column 215, and the other end is connected to the filter device 4; the filter device 4 is placed at the bottom of the cup, and the outlet of the filter device 4 is connected to the other end of the straw 3.

[0064] The filter device 4 is located at the bottom of the cup, so it does not block the sterilization light. Its simple structure makes it easy to carry. Water is poured in from above the filter device 4, filtered, and then drawn out through the straw. This not only filters impurities and heavy metals but also improves the taste of the water. Figure 4 The direction of the middle arrow indicates the direction of water flow. Water needs to enter from the top of the filter device 4 (containing the filter element). The water above the filter device 4 can be fully irradiated by ultraviolet light to kill bacteria. After the water flows through the filter device 4, it exits from the bottom inside the filter element. The bottom of the filter element's outer shell contacts the bottom of the cup, which can avoid the formation of a dead angle between the filter device 4 and the bottom of the cup.

[0065] In a preferred embodiment of this invention, the panel 211 is provided with a charging indicator light 2111 and a sterilization working indicator light 2113 window, a magnetic charging base 2112 charging hole, and a sterilization switch 2114 button hole.

[0066] In terms of product structure, the magnetic charging cable includes a male terminal component and a female terminal component coaxial with the male terminal component. It utilizes magnetic principles to achieve an attraction effect. The magnetic cable is relatively easy to use; a magnet is fixed to one end, and a magnetic material is also fixed to the other end. Simply bringing the two ends close together achieves charging. This invention employs magnetic charging technology, which offers advantages over traditional USB charging technology in that it is convenient to use, can be operated with one hand, is reversible, can be plugged in anywhere, is suitable for use anytime, charges quickly, meets the highest dust and water resistance rating (IPX8), and is small and space-saving.

[0067] In a preferred embodiment of this invention, a second waterproof ring 24, adapted to the outer shell 21 of the cup lid, is disposed in a groove near the upper end face of the outer ring of the screw cap. This effectively provides a sealing effect, preventing liquid from entering the cup lid and damaging the photoelectric components.

[0068] In a preferred embodiment of this invention, the screw cap further comprises an outer ring 223 and an inner ring 224. The inner wall of the outer ring 223 is provided with an internal thread, and the cup mouth 11 is provided with an external thread adapted to the internal thread. A third waterproof ring 25 adapted to the diameter of the cup mouth 11 is also provided at the junction of the outer ring 223 and the inner ring 224. This ensures a tight fit between the cup body and the cup cap, thereby achieving a good sealing effect.

[0069] Example 2

[0070] Based on Example 1, continue to refer to Figure 2 In this embodiment, the cup body is designed with multiple sizes according to capacity requirements. For cup bodies of different capacities, one to four sets of light source components 23 can be installed inside the screw cap, so as to reasonably control manufacturing costs while ensuring effective sterilization.

[0071] Example 3

[0072] Based on Example 1, continue to refer to Figure 2 and Figure 4 In this embodiment, the filtration device 4 includes at least two multi-layer filter elements selected from activated carbon, ion exchange resin, heavy metal filter element, ultrafiltration filter element, reverse osmosis membrane, or maifan stone. Multi-layer filter elements have a long service life, and the replacement cycle can be determined by referring to the influent water quality; generally, a replacement cycle of about one year is recommended.

[0073] As can be seen from the above embodiments, the intelligent ultraviolet sterilization filter straw cup provided by the present invention achieves at least the following beneficial effects:

[0074] 1. This invention utilizes capacitive sensing technology. When the cup lid is screwed into the cup body, the sensing element detects the metal cup mouth, and the chip turns on the ultraviolet light-emitting diode control switch to light up the sterilization light source for sterilization and disinfection. When the cup lid is screwed out of the cup body, the sensing element cannot detect the conductor, the ultraviolet light-emitting diode control switch cannot be turned on normally, and the sterilization light source cannot be lit, thereby preventing damage caused by ultraviolet leakage.

[0075] 2. This invention uses multi-layer filter materials, which can filter impurities and heavy metals, and also improve the taste of water. The filter device is installed on the straw and placed at the bottom of the cup, so it will not block the sterilization light. The structure is simple and easy to carry.

[0076] 3. This invention employs magnetic charging technology. Compared to traditional USB charging technology, magnetic charging technology offers the following advantages: 1) Convenient to use, operable with one hand, reversible, and suitable for use anytime; 2) Fast charging speed. The magnetic charging cable is designed to withstand high current transmission of 5A-30A, meeting the needs of fast charging and products requiring high current charging; 3) Waterproof protection. The female end of the magnetic charging cable can achieve the highest dustproof and waterproof rating (IPX8); 4) Small size and space saving. The magnetic charging cable has a small structural design, and the female end connector can be soldered to a printed circuit board for surface mounting and wire bonding.

[0077] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention.
