Referring to fig. 1 to 12, a multifunctional sterilizer 100 is used for cleaning and sterilizing a sterilization target. The sterilization target includes, but is not limited to, a teacup, a feeding bottle, a nipple, and the like. In the illustrated embodiment, a feeding bottle 91 and a nipple 92 are illustrated. The multi-function sterilizer 100 includes a housing 10, a cover 20, and a spray tube 40.

Referring to fig. 1, a base 10 includes a heating element 11 and a control circuit board (not shown) electrically connected to the heating element 11 for controlling the operation of the heating element 11. The heating element 11 may be provided on the bottom wall of the housing 10 or may be provided on the side wall of the housing 10. In the illustrated embodiment, the heating element 11 is provided at the bottom wall of the housing 10. The heating element 11 may be a brazing heating plate or an aluminum capacitor plate fixed to the bottom wall of the housing 10, but is not limited thereto.

The cover 20 is covered on the base 10. The cover body 20 and the base body 10 enclose together to form an accommodating space, and the accommodating space comprises a heating cavity 31, a working cavity 32 and a sewage cavity 33 which are arranged in a mutually partitioned manner. The term "partition arrangement" as used herein means that the heating chamber 31, the working chamber 32 and the sewage chamber 33 are respectively arranged in different areas in the accommodating space.

Referring to fig. 1 and 3 in combination, the heating chamber 31 is used to contain water and heat the water in the heating chamber 31 by the heating member 31. A spray pipe 40 is provided in the working chamber 32, and the spray pipe 40 communicates with the heating chamber 31. The sterilizing object such as the feeding bottle 91 is placed in the working chamber 32 and sleeved outside the injection tube 40, and the cleaning and sterilizing of the feeding bottle 91 are completed in the working chamber 32. The sewage chamber 33 is used for receiving sewage generated after washing and/or sterilization. The heating element 11 heats the water in the heating chamber 31, and the generated boiling water or steam is sprayed on the inner wall of the feeding bottle 91 through the spraying pipe 40, so that the fat, protein and the like remained on the inner wall of the feeding bottle 91 are dissolved, and flow into the sewage chamber 33 along the inner wall of the feeding bottle 91, thereby completing the cleaning and the disinfection of the feeding bottle 91.

Because heating chamber 31, working chamber 32 and sewage chamber 33 each other the subregion setting, the sewage that produces after the cleaning and disinfecting flows into sewage chamber 33, and can not flow into heating chamber 31 once more, so, avoided the repeated heating sewage to the disinfection mark such as feeding bottle 91 cause the pollution to guarantee that cleaning and disinfecting effect is better, satisfied user's demand effectively.

With continued reference to fig. 1, the heating chamber 31 is located at the bottom of the accommodating space, the sewage chamber 33 is located above the heating chamber 31, the injection pipe 40 is communicated with the heating chamber 31 through the injection channel 50, the injection channel 50 passes through the sewage chamber 33, and the "passing" refers to that the sidewall 51 of the injection channel 50 passes through the sewage chamber 33 in the up-down direction, and separates the chamber of the injection channel 50 and the sewage chamber 33 from each other. Since the sewage chamber 33 is located above the heating chamber 31, the sewage chamber 33 is simultaneously in the high-temperature steam during the cleaning and/or sterilizing process of the feeding bottle 11, that is, the sewage chamber 33 is also sterilized synchronously, thereby avoiding the breeding of bacteria in the sewage chamber 33 and further ensuring the clean and sanitary performance during the cleaning and/or sterilizing process.

In some embodiments, the sewage chamber 33 is located below the heating chamber 31, that is, the heating chamber 31 is located between the working chamber 32 and the sewage chamber 33, and sewage generated after the disinfection target is cleaned and/or sterilized flows from the working chamber 32 to the sewage chamber 33 through a pipe, which may pass through the heating chamber 31 or may be located outside the heating chamber 31. In other embodiments, the sewage chamber 33 is located outside the heating chamber 31, including, but not limited to, a sewage chamber 33 disposed on one side, two sides, and three sides of the heating chamber 31, a sewage chamber 33 surrounding the heating chamber 31, a sewage chamber 33 semi-surrounding the heating chamber 31, and a sewage chamber 33 partially surrounding the heating chamber 31.

The volume of the sewage chamber 33 is greater than or equal to the volume of the heating chamber 31, so that the sewage generated is sufficiently contained in use without overflowing, thereby avoiding pollution of the sterilizing object such as a milk bottle caused by overflowing sewage.

The sewage chamber 33, the spray passage 50 and the spray pipe 40 are detachably installed in the receiving space. Thus, after the sewage chamber 33, the spray passage 50 and the spray pipe 40 are taken out, the multifunctional sterilizer 100 can be used as a cooking device to cook or heat food, a steaming grid can be placed in the accommodating space, the multifunctional sterilizer 100 can also be used as a milk warmer to heat a milk bottle filled with breast milk, the multifunctional sterilizer 100 can also be used as a common sterilizing device, namely, a certain amount of water is added into the accommodating space, and sterilizing targets such as the milk bottle are placed in the water for sterilization by heating, and the like, which are not listed herein. Thus, the multifunctional sterilizer 100 has various functions.

The spray pipe 40 is integrally formed with the spray channel 50, and/or the spray channel 50 is integrally formed with the sewage chamber 33. In the embodiment shown in fig. 1, the sewage chamber 33, the spraying channel 50 and the spraying pipe 40 are integrally formed, so that the three can be filled into the accommodating space together, and the use is convenient and quick. In other embodiments, the injection passage 50 is integrally formed with both the soil chamber 33, or the injection passage 50 is integrally formed with the injection pipe 40.

The sewage chamber 33 includes a bottom wall 331 covering the heating chamber 31 and an outer wall 332 matching with the inner wall of the base 10. In this way, the steam generated in the heating chamber 31 can be fully utilized to sterilize the sewage chamber 33. In the illustrated embodiment, the bottom wall 331 is integrally formed to extend radially outwardly from the side wall 51 of the injection passage 50, and the outer wall 332 is integrally formed to extend upwardly from an outer edge of the bottom wall 331.

Referring to fig. 1 and 2 in combination, an upper cover 34 is further disposed on the top of the sewage chamber 33 and covers the outer wall 332, and the upper cover 34 is provided with a water inlet 341 for allowing sewage to pass through and a through hole 342 matched with the spraying channel 50. Thus, the feeding bottle 91 or the like to be cleaned is made less likely to be contaminated with sewage. Referring to fig. 1, the feeding bottle 91 may be supported on the upper cover 34, and sewage generated by washing the feeding bottle 91 flows to the upper cover 34 and flows into the sewage chamber 33 through the water inlet hole 341.

The outer wall 332 of the sewage chamber 33 and the inner wall of the base 10 and/or the upper cover 34 and the inner wall of the base 10 are sealed by a sealing ring 333. The sealing ring 333 is arranged, so that sewage generated in cleaning and disinfecting can not flow into the heating cavity 31 from between the outer wall 332 of the sewage cavity 33 and the inner wall of the base body 10, and therefore, water in the heating cavity 31 is clean and sanitary, and a good cleaning effect is further ensured.

With continued reference to fig. 1 and 2, a groove 3321 is formed on the outer side of the outer wall 332, and the seal ring 333 is installed in the groove 3321. Thus, the seal ring 333 can be stably and reliably mounted in the groove 3321, and is not easy to fall off. In this embodiment, the sealing ring 333 includes an annular main body portion 3331 and a rib 3332 protruding outward from the main body portion 3331, where the rib 3332 protrudes outward from the outer surface of the outer wall 332 to form a sealing engagement with the inner wall of the base 10. In the illustrated embodiment, the number of the ribs 3332 is 3, and the ribs are uniformly distributed along the up-down direction outside the main body portion 3331, which is not limited thereto.

The inner wall of the base 10 is provided with a step portion 15, and the sewage chamber 33 is supported by the step portion 15. In this way, the sewage chamber 33 and the like can be quickly and reliably installed in the accommodation space. The heating chamber 31 is formed below the bottom wall 331 of the sewage chamber 33, and the heating chamber 31 can be sized by setting the height of the step 15.

Referring to fig. 5 to 7, the injection passage 50 may have any shape including, but not limited to, a cylindrical shape, a conical shape, and an inverted conical shape.

The side wall 51 of the injection channel 50 protrudes downwards from the bottom wall 331 of the sewage chamber 33 and into the heating chamber 31. Referring to fig. 1, in use, the lower end of the side wall 51 of the injection passage 50 is immersed in the water in the heating chamber 31, so that a closed cavity 36 is formed between the liquid surface in the heating chamber 31 and the bottom wall 331 of the sewage chamber 33, and the sealing ring 333 ensures good sealing performance of the cavity 36. During the process of heating water to boiling, a large amount of steam is generated by the water into the cavity 36, so that the pressure of the cavity 36 is rapidly increased, the boiled water is forced to enter the injection tube 40 through the injection passage 50 by the pressure in the cavity 36, and is injected on the inner wall of the feeding bottle 91 through the injection tube 40, and sewage generated after the injection flows into the sewage chamber 33 along the inner wall of the feeding bottle 91. Until the liquid level in the heating chamber 31 is lower than the lower end of the side wall 51 of the injection passage 50, the cavity 36 is not closed any more, boiling water cannot be caused to enter the injection pipe 40 any more, at this time, steam generated by the water enters the injection pipe 40 through the injection passage 50 and is injected on the inner wall of the feeding bottle 91 through the injection pipe 40 to further clean and disinfect the feeding bottle 91, the steam is condensed into liquid on the inner wall of the feeding bottle 91, and the liquid flows into the sewage chamber 33 along the inner wall of the feeding bottle 91.

The height H1 of the side wall 51 of the injection passage 50 protruding from the bottom wall 331 is not more than 200 mm, that is, the height H1 of the side wall 51 of the injection passage 50 protruding from the bottom wall 331 is between 0mm and 200 mm, so that the depth of the injection passage 50 immersed in water can approach 200 mm. In this way, it is possible to ensure that there is sufficient time and water amount to wash the feeding bottle 91. Preferably, the length H1 of the side wall 51 of the ejection channel 50 protruding from the bottom wall 331 ranges from 5mm to 80 mm. Thus, not only space is saved, but also sufficient time and water are ensured to clean the feeding bottle 91.

The height H2 of the ejector tube 40 is not more than 1000 mm, that is, the height H2 of the ejector tube 40 is between 0mm and 1000 mm, thereby ensuring sufficient cleaning of the feeding bottle having a large height. In some preferred embodiments, the height H2 of the ejector tube 40 ranges between 100 millimeters and 400 millimeters. Therefore, the space can be saved, and the feeding bottle with larger height can be fully cleaned.

Referring to fig. 8, the multi-function sterilizer 100 includes 2 spray pipes 40, and the height of the spray pipes 400 is in the above-described range or the like, for example, 150 mm. In the embodiment shown in fig. 8, one of the spray pipes 40 cleans and disinfects the feeding bottle 91, and the other spray pipe 40 cleans and disinfects the nipple 92, and boiling water or steam sprayed from the spray pipe 40 cleaning the nipple 92 can also clean and disinfect the outer side of the feeding bottle 91 due to the small size of the nipple 92.

The spray pipe 40 includes a water storage section 41 and a spray section 42, the water storage section 41 is connected with the spray channel 50, and the spray section 42 includes an upper opening 421 provided at a top end and/or a plurality of spray holes 422 provided at a pipe wall. The pipe wall of the water storage section 41 is not provided with injection holes. Referring to fig. 1, the whole of the sewage chamber 33, the injection passage 50 and the injection tube 40 is integrally formed and placed in the accommodating space, when the lower end of the side wall 51 of the injection passage 50 is immersed in the water in the heating chamber 31 and then continuously lowered, the pressure in the cavity 36 is gradually increased to cause the water in the heating chamber 31 to be pressed into the injection tube 40 through the injection passage 50, so that the water pressed in the process can be kept in the water storage section 41 to avoid waste caused by overflow of the water from the injection hole 422, in addition, during heating, steam generated in the heating process enters the cavity 36 to gradually increase the pressure in the cavity 36 to cause the water in the heating chamber 31 to be pressed into the injection tube 40 through the injection passage 50, but before the water in the heating chamber 31 boils, the pressure in the cavity 36 is insufficient to cause the water to be injected onto the inner wall of the milk bottle 91 and can only flow down along the outer wall of the injection tube 40, and the water can be kept in the water storage section 41 by the water storage section 41 without waste caused by overflow.

In the illustrated embodiment, the walls of the water storage section 41 slope from bottom to top and inwardly so that water can more smoothly enter the spray section 42 from the water storage section 41 during spraying. Of course, the walls of the water storage section 41 may also be straight, i.e. not inclined.

The height H3 of the water storage section 41 is not greater than 200 mm, that is, the height H3 of the water storage section 41 is between 0mm and 200 mm, so that water entering the spray pipe 40 under pressure of the cavity 36 can be maintained in the water storage section 41 before the water is boiled and sprayed, without wasting. The height of the water storage section 41 can be selected as desired. Preferably, the height of the water storage section 41 ranges from 30 mm to 120 mm, which saves space and does not waste water.

The pipe wall of the spraying section 42 is inclined inwards from bottom to top, and the inclined angle is not more than 85 degrees.
