[0031] In today's social context of increasing health awareness, people pay more and more attention to the sanitary conditions of their living environment. Among the tools for maintaining daily cleanliness and preventing the spread of diseases, disinfectors have become particularly important. Disinfectors generally include a liquid storage cup for storing disinfectant, and the liquid storage cup is provided with an air inlet and an air outlet for gas circulation. However, the liquid storage cup of a traditional disinfector is easily knocked over by pets or children during use, causing the disinfectant to flow out of the air inlet and the air outlet, resulting in a waste of disinfectant and reducing the utilization rate of the disinfectant. To this end, the utility model proposes a liquid storage cup, which is intended to reduce the possibility of leakage and waste of disinfectant when the liquid storage cup is knocked over or turned upside down.

[0032] See also Figures 1 to 3 In one embodiment of the utility model, the liquid storage cup is used for a sterilizer, the sterilizer includes a shell 500 and a fan 400 arranged on the shell, the liquid storage cup includes a cup body, the cup body includes a cup body 100 and a cup cover 200, the cup body 100 has a receiving cavity 110 for receiving liquid, the cup cover 200 has a cavity opening arranged in the receiving cavity 110, and has an air inlet 210 and an air outlet 220, the cup cover 200 is provided with a first channel 231 and a second channel 241 both communicated with the receiving cavity 110, the first channel 231 and the second channel 241 are connected to the receiving cavity 110, and the first channel 231 and the second channel 241 are connected to ... The upper port of a channel 231 is connected to the air outlet 220 and the lower port extends into the accommodating chamber 110, the upper port of the second channel 241 is connected to the air inlet 210 and the lower port extends into the accommodating chamber 110, the accommodating chamber 110 has a leak-proof water level 111, when the liquid level in the accommodating chamber 110 does not exceed the leak-proof water level 111, the cup body is in an upright, sideways or inverted posture, the lower port of the first channel 231 and the lower port of the second channel 241 are both located above the liquid level in the accommodating chamber 110.

[0033] In order to facilitate understanding of this solution, the working principle of the sterilizer is first introduced. The sterilizer includes a liquid storage cup, a housing 500 mounted on the outside of the liquid storage cup, a fan 400 for driving air to circulate in the liquid storage cup, and a stirring mechanism for stirring the liquid in the liquid storage cup. The liquid mentioned in this article is introduced by taking the disinfectant 800 as an example. The disinfectant 800 is placed in the liquid storage cup. Under the stirring of the stirring mechanism, the disinfectant component with a sterilizing function in the disinfectant 800 generates a sterilizing gas that is separated from the liquid, and the sterilizing gas is guided to the air outlet 220 through the fan 400 to sterilize and disinfect the surrounding environment. If the sterilizer is knocked over or turned upside down during operation, the disinfectant 800 in the liquid storage cup is easy to flow out from the air outlet 220 and the air inlet 210, thereby causing a waste of the disinfectant 800, reducing the utilization rate of the disinfectant 800, and the leaked disinfectant 800 may be ingested by pets or children, causing damage to the health of pets or humans.

[0034] Therefore, a first channel 231 and a second channel 241 for ventilation are provided on the cup cover 200, and a leakproof water level 111 is provided on the cup body 100. The leakproof water level 111 is provided below the lower end of the first channel 231 extending into the accommodating chamber 110. The disinfectant 800 enters the accommodating chamber 110 through the first channel 231, and the disinfectant 800 whose liquid level does not exceed the leakproof water level 111 is put in. When the cup body is placed upright, the liquid level of the disinfectant 800 in the accommodating chamber 110 is below the lower end of the first channel 231, so that the disinfectant gas can smoothly flow to the air outlet 220 through the first channel 231. If normal gas exchange cannot be completed, the disinfectant gas in the accommodating chamber 110 will be difficult to be guided to the air outlet 220 by the fan 400, which will reduce the disinfection effect of the sterilizer and may even cause damage to the fan 400, thereby reducing the liquid level of the disinfectant 800 and the first channel 2 31, resulting in the possibility of difficulty in completing gas exchange inside the sterilizer; when the cup body is inverted, the liquid level of the disinfectant 800 in the accommodating chamber 110 is lower than the lower port of the first channel 231 and the second channel 241 extending into the accommodating chamber 110, making it difficult for the disinfectant 800 in the accommodating chamber 110 to flow out through the first channel 231 and the second channel 241, thereby improving the anti-leakage performance of the liquid storage cup; when the cup body is placed on its side, the liquid level of the disinfectant 800 is lower than the end of the second channel 241 extending into the accommodating chamber 110, making it difficult for the disinfectant 800 in the accommodating chamber to flow out from the second channel 241 and the first channel 231, thereby improving the anti-leakage performance of the liquid storage cup. In summary, the liquid storage cup proposed in this solution can effectively reduce the possibility of leakage of the disinfectant 800 when the liquid storage cup is placed on its side or inverted, reduce the waste of the disinfectant 800, and ensure the utilization rate of the disinfectant 800.

[0035] It is worth mentioning that the utility model is also suitable for volatilization of aromatherapy liquids. The aromatherapy liquid is filled into the liquid storage cup and stirred to volatilize the aromatherapy liquid, which has a better effect than general ultrasonic atomization.

In this way, the first channel 231 is provided in the middle of the cup cover 200, and the second channel 241 is provided around the outer circumference of the first channel 231, so that the circumferential side wall of one end of the second channel 241 extending into the accommodating chamber 110 and the circumferential inner wall of the opposite accommodating chamber 110 are the same distance. After the disinfectant 800 not exceeding the anti-leakage water level 111 is poured into the liquid storage cup, when the liquid storage cup is placed on its side, even if the liquid storage cup rolls, the distance between the liquid level of the disinfectant 800 in the accommodating chamber 110 and the side wall of the second channel 241 close to the liquid level is always the same, and the liquid level is always lower than the side wall of the second channel 241 close to the liquid level, so that the disinfectant 800 in the accommodating chamber is not easy to flow out from the gap between the second channel 241 and the first channel 231, thereby improving the anti-leakage performance of the liquid storage cup.

[0037] Optionally, in one embodiment, when the cup body is in an upright position, the lower end of the first channel 231 is lower than the lower end of the second channel 241. In this way, the outside air flows in from the air inlet 210 and flows into the accommodating chamber 110 through the gap between the first channel 231 and the second channel 241. When the cup body is in a square position, the lower end of the first channel 231 is arranged below the lower end of the second channel 241, which increases the path of the outside air flowing from the accommodating chamber 110 to the first channel 231, so that the air flowing into the accommodating chamber 110 from the second channel 241 will not be immediately guided to the air outlet 220 by the fan 400, which will reduce the air circulation efficiency and increase the energy consumption of the fan 400.

[0038] Optionally, in another embodiment, the second channel 241 and the lower port of the first channel 231 may be arranged in various forms, and the lower ports of the first channel 231 and the second channel 241 may be arranged flush with each other.

The lower end of the first tube column 230 passes through the lower cover plate 260 and extends into the accommodating cavity 110. The air outlet 220 is formed at the upper end of the first tube column 230, and the first channel 231 is formed on the inner wall of the first tube column 230. In this way, the upper cover plate 250, the lower cover plate 260, and the side panel 270 enclose a cup cover 200 with a cavity, the air inlet 210 is set on the upper cover plate 250, and the lower cover plate 260 seals the cup mouth of the cup body to isolate the air inlet 210 from the accommodating cavity 110, so that when the liquid storage cup is placed on its side or upside down, the disinfectant 800 is not easy to flow out from the air inlet 210 of the cup cover 200, thereby improving the anti-leakage performance of the liquid storage cup when placed on its side or upside down; the first channel 231 is formed on the inner wall of the first tube column 230, so that the disinfectant gas can flow along the first tube column 230 to the air outlet 220 to be discharged from the liquid storage cup, and the structure of the upper cover plate 250 is integrally formed to make the structure of the cup cover 200 more compact and stable.

In this way, the annular seam section 242 is formed between the outer wall surface of the first pipe section and the inner wall surface of the second pipe section, and the annular cavity section 243 is formed between the upper cover plate 250 and the lower cover plate 260. The annular cavity section 243 is connected with the air inlet hole 210, so that the outside air enters the annular cavity section 243 from the air inlet hole 210, and then enters the accommodating cavity 110 through the annular seam section 242, so that the outside air enters the accommodating cavity 110 for air exchange. The annular cavity section 243 is connected with the accommodating cavity 110 only through the annular seam section 242, so that when the liquid storage cup is placed on its side or inverted, the disinfectant 800 in the accommodating cavity 110 is not easy to flow out of the air inlet hole 210 directly from the lower cover plate 260, thereby improving the anti-leakage performance of the liquid storage cup when it is placed on its side or inverted.

[0042] Optionally, in another embodiment, the inner wall of the second tube column 240 can be tightly fitted to the outer wall of the second tube column 240, eliminating the setting of the annular gap section 242, and opening a through hole connected to the accommodating cavity 110 on the tube side wall of the second tube section.
