[0002] As living standards improve, people's requirements for hygiene also increase. Sterilization devices for cleaning and disinfecting utensils or containers such as baby bottles, nipples, teacups, and bowls have appeared on the market. The general practice is to use a simple water kettle to heat the utensils or containers to be disinfected for cleaning and disinfection, but the cleaning and disinfection effect is not good and cannot meet people's needs. Summary of the invention

[0003] The purpose of the present application is to provide a multifunctional sterilizer with good cleaning and sterilizing effects.

[0004] One aspect of the present application provides a multifunctional sterilizer. The multifunctional sterilizer comprises: a base body, including a heating element; a cover body, which is covered on the base body; and a spray pipe; wherein the cover body and the base body are jointly enclosed to form a receiving space, the receiving space comprises a heating chamber, a working chamber and a sewage chamber which are arranged in partitions with each other, the spray pipe is arranged in the working chamber, and the spray pipe is connected with the heating chamber, the sewage chamber is used to receive sewage generated after cleaning and / or sterilization, and the heating chamber and the sewage chamber are isolated from each other, the heating chamber is located at the bottom of the receiving space, the sewage chamber is located above the heating chamber, the spray pipe is connected with the heating chamber through a spray channel, and the spray channel passes through the sewage chamber.

[0005] Optionally, the sewage chamber includes a bottom wall covering the heating chamber and an outer wall cooperating with the inner wall of the seat body, so that the steam generated in the heating chamber can be fully utilized to disinfect the sewage chamber.

[0006] Optionally, the side wall of the injection channel protrudes from the bottom wall of the sewage chamber and extends into the heating chamber. When in use, the lower end of the side wall of the injection channel is immersed in the water in the heating chamber, so that a closed cavity is formed between the liquid surface in the heating chamber and the bottom wall of the sewage chamber, and the arrangement of the sealing ring ensures that the cavity has good sealing performance. In the process of heating water to boiling, the water generates a large amount of steam that enters the cavity, so that the pressure of the cavity increases rapidly. The pressure in the cavity prompts the boiling water to enter the injection pipe through the injection channel and is sprayed on the inner wall of the milk bottle through the injection pipe. The sewage generated after spraying flows into the sewage chamber along the inner wall of the milk bottle. When the liquid level in the heating chamber is lower than the lower end of the side wall of the injection channel, the cavity is no longer closed and can no longer prompt the boiling water to enter the injection pipe. At this time, the steam generated by the water enters the injection pipe through the injection channel and is sprayed on the inner wall of the milk bottle through the injection pipe to further clean and disinfect the milk bottle. The steam condenses into liquid on the inner wall of the milk bottle and also flows into the sewage chamber along the inner wall of the milk bottle.

[0007] Optionally, the side wall of the injection channel protrudes from the bottom wall by a height of no more than 200 mm. In this way, sufficient time and water can be guaranteed to clean the feeding bottle.

[0055] See also Figures 1 to 12 The multifunctional sterilizer 100 is used to clean and sterilize the sterilization target. The sterilization target includes tea cups, milk bottles, pacifiers, etc., but is not limited thereto. In the illustrated embodiment, a milk bottle 91 and a pacifier 92 are used as examples for illustration. The multifunctional sterilizer 100 includes a seat body 10, a cover body 20 and a spray pipe 40.

[0056] See also Figure 1 The seat 10 includes a heating element 11 and a control circuit board (not shown), and the control circuit board is electrically connected to the heating element 11 for controlling the operation of the heating element 11. The heating element 11 can be disposed on the bottom wall of the seat 10 or on the side wall of the seat 10. In the illustrated embodiment, the heating element 11 is disposed on the bottom wall of the seat 10. The heating element 11 can be a brazed heating plate or an aluminum capacitor plate fixed to the bottom wall of the seat 10, but is not limited thereto.

[0057] The cover body 20 is covered on the base body 10. The cover body 20 and the base body 10 are jointly enclosed to form a receiving space, and the receiving space includes a heating chamber 31, a working chamber 32 and a sewage chamber 33 that are mutually partitioned. The "partitioned arrangement" mentioned here means that the heating chamber 31, the working chamber 32 and the sewage chamber 33 are respectively arranged in different areas in the receiving space.

[0058] Please refer to Figure 1 and Figure 3 The heating chamber 31 is used to contain water, and the water in the heating chamber 31 is heated by the heating element 31. The spray pipe 40 is arranged in the working chamber 32, and the spray pipe 40 is connected to the heating chamber 31. The sterilization target such as the milk bottle 91 is placed in the working chamber 32 and is sleeved on the outside of the spray pipe 40, and the cleaning and sterilization of the milk bottle 91 is completed in the working chamber 32. The sewage chamber 33 is used to receive the sewage generated after cleaning 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 milk bottle 91 through the spray pipe 40, dissolving the fat, protein, etc. remaining on the inner wall of the milk bottle 91, and flows into the sewage chamber 33 along the inner wall of the milk bottle 91, thereby completing the cleaning and sterilization of the milk bottle 91.

[0059] Since the heating chamber 31, the working chamber 32 and the sewage chamber 33 are arranged in partitions with each other, the sewage generated after cleaning and disinfection flows into the sewage chamber 33, and will not flow into the heating chamber 31 again. In this way, the repeated heating of sewage to contaminate the disinfection targets such as the baby bottle 91 is avoided, thereby ensuring a better cleaning and disinfection effect and effectively meeting the needs of users.

[0060] Please continue reading Figure 1 , the heating chamber 31 is located at the bottom of the receiving space, the sewage chamber 33 is located above the heating chamber 31, the injection pipe 40 is connected to the heating chamber 31 through the injection channel 50, and the injection channel 50 passes through the sewage chamber 33. The "passing through" mentioned here means that the side wall 51 of the injection channel 50 passes through the sewage chamber 33 in the up and down direction, and the cavity of the injection channel 50 and the sewage chamber 33 are isolated from each other. Since the sewage chamber 33 is located above the heating chamber 31, during the cleaning and / or sterilization process of the feeding bottle 11, the sewage chamber 33 is simultaneously in high-temperature steam, that is, the sewage chamber 33 is also sterilized synchronously, avoiding the growth of bacteria in the sewage chamber 33, thereby ensuring the cleanliness and hygiene of the cleaning and / or sterilization process.

[0061] 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 the sewage generated after cleaning and / or disinfecting the disinfection target flows from the working chamber 32 to the sewage chamber 33 through a pipe, and the pipe can pass through the heating chamber 31 or be located outside the heating chamber 31. In other embodiments, the sewage chamber 33 is located outside the heating chamber 31, including the following situations: the sewage chamber 33 is set on one side, two sides, or three sides of the heating chamber 31; the sewage chamber 33 surrounds the heating chamber 31; the sewage chamber 33 half surrounds the heating chamber 31; the sewage chamber 33 partially surrounds the heating chamber 31, and is not limited thereto.

[0062] The volume of the sewage chamber 33 is greater than or equal to the volume of the heating chamber 31 , so that it is sufficient to accommodate the sewage generated during use without overflowing, thereby preventing the overflowed sewage from contaminating the sterilized objects such as milk bottles.

[0063] The sewage chamber 33, the injection channel 50 and the injection pipe 40 are detachably installed in the receiving space. In this way, after the sewage chamber 33, the injection channel 50 and the injection pipe 40 are taken out, the multifunctional sterilizer 100 can be used as a cooking device to cook or heat food, and a steaming rack can be placed in the receiving space; the multifunctional sterilizer 100 can also be used as a milk warmer to heat the milk bottle containing breast milk; the multifunctional sterilizer 100 can also be used as a common sterilizing device, that is, a certain amount of water is added to the receiving space, and then the sterilizing target such as the milk bottle is placed in the water, and sterilized by heating, etc., which are not listed here one by one. In this way, the multifunctional sterilizer 100 has multiple functions.

[0064] The injection pipe 40 is integrally formed with the injection channel 50; and / or the injection channel 50 is integrally formed with the sewage chamber 33. Figure 1 In the embodiment shown, the sewage chamber 33, the injection channel 50 and the injection pipe 40 are integrally formed, so that the three can be put into the receiving space together, which is convenient and quick to use. In other embodiments, the injection channel 50 and the sewage chamber 33 are integrally formed; or, the injection channel 50 and the injection pipe 40 are integrally formed.

[0065] The sewage chamber 33 includes a bottom wall 331 covering the heating chamber 31 and an outer wall 332 cooperating with the inner wall of the seat body 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 extended radially outward from the side wall 51 of the injection channel 50, and the outer wall 332 is integrally extended upward from the outer edge of the bottom wall 331.

[0066] Please refer to Figure 1 and Figure 2 The top of the sewage chamber 33 is also provided with an upper cover 34 which covers the outer wall 332, and the upper cover 34 is provided with a water inlet hole 341 for sewage to pass through and a through hole 342 which cooperates with the injection channel 50. In this way, the milk bottle 91 to be washed is not easily contaminated by the sewage. Referring to FIG. 1 , the milk bottle 91 can be supported on the upper cover 34, and the sewage generated by washing the milk bottle 91 flows to the upper cover 34 and flows into the sewage chamber 33 through the water inlet hole 341.

[0067] A seal is formed between the outer wall 332 of the sewage chamber 33 and the inner wall of the base body 10, and / or between the upper cover 34 and the inner wall of the base body 10 through a sealing ring 333. The provision of the sealing ring 333 prevents sewage generated during cleaning and disinfection from flowing into the heating chamber 31 from between the outer wall 332 of the sewage chamber 33 and the inner wall of the base body 10, so that the water in the heating chamber 31 is clean and sanitary, further ensuring a good cleaning effect.

[0068] Please continue reading Figure 1 and Figure 2 , a groove 3321 is provided on the outer side of the outer wall 332, and the sealing ring 333 is installed in the groove 3321. In this way, the sealing ring 333 can be stably and reliably installed in the groove 3321 and is not easy to fall off. In this embodiment, the sealing ring 333 includes an annular main body 3331 and a convex rib 3332 protruding outward from the main body 3331, and the convex rib 3332 protrudes outward from the outer side surface of the outer wall 332 to form a sealing fit with the inner wall of the seat body 10. In the illustrated embodiment, the convex rib 3332 is set to 3, which are evenly distributed in the up and down direction on the outer side of the main body 3331, but is not limited thereto.

[0069] The inner wall of the seat body 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 can be quickly and reliably installed in the receiving space. The heating chamber 31 is formed below the bottom wall 331 of the sewage chamber 33, and the size of the heating chamber 31 can be set by setting the height of the step portion 15.

[0070] See also Figures 5 to 7 The shape of the injection channel 50 can be any of the following: cylindrical, conical, inverted conical, but not limited thereto.

[0071] The side wall 51 of the injection channel 50 protrudes downward from the bottom wall 331 of the sewage chamber 33 and extends into the heating chamber 31. Figure 1When in use, the lower end of the side wall 51 of the injection channel 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 arrangement of the sealing ring 333 ensures that the cavity 36 has good sealing performance. In the process of heating water to boiling, a large amount of steam is generated by the water and enters the cavity 36, so that the pressure of the cavity 36 increases rapidly. The pressure in the cavity 36 prompts the boiling water to enter the injection pipe 40 through the injection channel 50, and is injected onto the inner wall of the milk bottle 91 through the injection pipe 40. The sewage generated after spraying flows into the sewage chamber 33 along the inner wall of the milk bottle 91. When the liquid level in the heating chamber 31 is lower than the lower end of the side wall 51 of the injection channel 50, the cavity 36 is no longer closed and the boiling water can no longer enter the injection pipe 40. At this time, the steam generated by the water enters the injection pipe 40 through the injection channel 50 and is sprayed onto the inner wall of the milk bottle 91 through the injection pipe 40 to further clean and disinfect the milk bottle 91. The steam condenses into liquid on the inner wall of the milk bottle 91 and also flows into the sewage chamber 33 along the inner wall of the milk bottle 91.

[0072] The height H1 of the side wall 51 of the jet channel 50 protruding from the bottom wall 331 is not greater than 200 mm, that is, the height H1 of the side wall 51 of the jet channel 50 protruding from the bottom wall 331 is between 0 mm and 200 mm, so that the depth of the jet channel 50 immersed in water can be close to 200 mm. In this way, sufficient time and water can be guaranteed to clean the milk bottle 91. Preferably, the length H1 of the side wall 51 of the jet channel 50 protruding from the bottom wall 331 ranges from 5 mm to 80 mm. In this way, space can be saved and sufficient time and water can be guaranteed to clean the milk bottle 91.

[0073] The height H2 of the spray pipe 40 is not greater than 1000 mm, that is, the height H2 of the spray pipe 40 is between 0 mm and 1000 mm, thereby ensuring that a relatively high milk bottle can be fully cleaned. In some preferred embodiments, the height H2 of the spray pipe 40 is between 100 mm and 400 mm. In this way, space can be saved and relatively high milk bottles can be fully cleaned.

[0074] See also Figure 8 The multifunctional sterilizer 100 includes two spray pipes 40, and the height of the spray pipes 400 is within the above range, for example, 150 mm. The multifunctional sterilizer 100 can clean two milk bottles 91 and two nipples at the same time. Figure 8 In the illustrated embodiment, one of the spray tubes 40 cleans and disinfects the milk bottle 91, and the other spray tube 40 cleans and disinfects the nipple 92. Since the nipple 92 is relatively small in size, the boiling water or steam sprayed from the spray tube 40 for cleaning the nipple 92 can also clean and disinfect the outside of the milk bottle 91.

[0075] The injection pipe 40 includes a water storage section 41 and an injection section 42. The water storage section 41 is connected to the injection channel 50. The injection section 42 includes an upper opening 421 disposed at the top and / or a plurality of injection holes 422 disposed on the pipe wall. The pipe wall of the water storage section 41 is not provided with injection holes. Figure 1 , the sewage chamber 33, the jet channel 50 and the jet pipe 40 are placed in the receiving space. When the lower end of the side wall 51 of the jet channel 50 is immersed in the water of the heating chamber 31 and then continues to be lowered, the pressure in the cavity 36 gradually increases, prompting the water in the heating chamber 31 to be pressed into the jet pipe 40 through the jet channel 50. In this way, the water storage section 41 is set so that the water pressed up in this process can be kept in the water storage section 41, thereby avoiding the water from overflowing from the jet hole 422 and causing waste; in addition, during the heating process, the steam generated enters the cavity 36, so that the pressure in the cavity 36 gradually increases, prompting the water in the heating chamber 31 to be pressed into the jet pipe 40 through the jet channel 50. However, before the water in the heating chamber 31 boils, the pressure in the cavity 36 is not enough to prompt the water to be sprayed from the jet hole to the inner wall of the milk bottle 91, and can only flow down along the outer wall of the jet pipe 40. By setting the water storage section 41, the water can be kept in the water storage section 41, and will not overflow from the jet hole and cause waste.

[0076] In the illustrated embodiment, the wall of the water storage section 41 is inclined inward from bottom to top, so that when spraying, water can more smoothly enter the spraying section 42 from the water storage section 41. Of course, the wall of the water storage section 41 can also be a straight wall, that is, not inclined.

[0077] 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 0 mm and 200 mm, so that before the water boils and sprays, the water entering the spray pipe 40 under the pressure of the cavity 36 can be kept in the water storage section 41 without causing waste. The height of the water storage section 41 can be selected according to needs. Preferably, the height of the water storage section 41 ranges from 30 mm to 120 mm, so that space can be saved and water will not be wasted.

[0078] The tube wall of the spray section 42 is inclined inward from bottom to top, and the inclination angle is not greater than 85 degrees. Since the tube wall of the spray section 42 is inclined inward from bottom to top, the boiling water or steam entering the spray section 42 is subjected to the pressure of the tube wall, so that it can be sprayed onto the inner wall of the milk bottle 91 through the upper opening 421 or the spray hole 422 with greater force, so that the spraying effect is good.

[0079] Preferably, the angle of inclination of the tube wall of the spray section 42 is between 2 and 30 degrees. In this way, the boiling water or steam entering the spray section 42 can be sprayed onto the inner wall of the milk bottle 91 through the upper opening 421 or the spray hole 422 with sufficient force, and the spraying effect is better. At the same time, the spray pipe 40 can be ensured to have a high height, so that milk bottles 91 of different heights can be fully sprayed.

[0080] The plurality of injection holes 422 are evenly or unevenly distributed on the tube wall of the injection section 42. The area of ​​the single injection hole 422 ranges from 0.13 square millimeters to 314 square millimeters. Within this range, the boiling water or steam entering the injection section 42 can be well sprayed onto the inner wall of the milk bottle 91 through the injection hole 422, while ensuring that the injection section 42 has a certain strength. Preferably, the area of ​​the single injection hole 422 ranges from 7 square millimeters to 100 square millimeters. Within this range, the boiling water or steam entering the injection section 42 can be sprayed onto the inner wall of the milk bottle 91 through the injection hole 422 in sufficient quantity, while ensuring that the injection section 42 has better strength.

[0081] On a single spray pipe 40, the number of the spray holes 422 of the spray section 42 ranges from 2 to 120. In this way, sufficient cleaning and / or disinfection of the disinfection target can be achieved.

[0082] The area of ​​the lower opening 55 of the injection channel 50 is larger than the area of ​​the upper opening 421 of the injection pipe 40. In this way, during the cleaning and disinfection process, it is possible to ensure that more boiling water or steam enters the injection pipe 40 through the lower opening 55, and the boiling water or steam ejected from the upper opening 421 is relatively strong. In one embodiment, the injection pipe 40 is not provided with an upper opening, but only with an injection hole 422.

[0083] The area range of the upper opening 421 is between 0 square millimeters and 5000 square millimeters, and the area range of the lower opening 55 is between 78 square millimeters and 282600 square millimeters. In this way, during the cleaning and disinfection process, it can be ensured that enough boiling water or steam enters the injection pipe 40 through the lower opening 55, and the boiling water or steam sprayed from the upper opening 421 is strong enough. Preferably, the area range of the upper opening 421 is between 12 square millimeters and 3500 square millimeters, and the area range of the lower opening 55 is between 100 square millimeters and 235600 square millimeters. In this way, during the cleaning and disinfection process, it can be ensured that more boiling water or steam enters the injection pipe 40 through the lower opening 55, and the boiling water or steam sprayed from the upper opening 421 is stronger.

[0084] The upper opening 421 is a single through hole; or, the upper opening 421 includes a plurality of through holes, and the area of ​​the upper opening 421 is the sum of the areas of the plurality of through holes. The through hole may be a regular or irregular shape such as a circle, a square, a polygon, etc. In the illustrated embodiment, the upper opening 421 is a single through hole.

[0085] The lower opening 55 is a single through hole; or, the lower opening 55 includes a plurality of through holes (see Figure 4 ), the area of ​​the lower opening 55 is the sum of the areas of the plurality of through holes. The through holes may be in regular or irregular shapes such as circular, square, polygonal, etc. Figure 1 , the lower opening 55 is a single through hole.

[0086] The spray pipe 40 can be one or more. When there is one spray pipe 40, the multifunctional sterilizer 100 can only clean one milk bottle 91 at a time. At this time, the power range of the heating element 11 is between 150 watts and 1000 watts, so that sufficient steam volume and steam pressure can be generated to clean the milk bottle 91. The power range of the heating element 11 is further preferably between 300 watts and 900 watts, so that the spray cleaning effect is better.

[0087] When there are multiple spray pipes 40 (including 2 or more), the multifunctional sterilizer 100 can clean multiple milk bottles 91 at a time. At this time, the power range of the heating element 11 is between 300 watts and 3000 watts, so that sufficient steam volume and steam pressure can be generated to clean the milk bottles 91. The power range of the heating element 11 is further preferably between 400 watts and 2000 watts, so that the spray cleaning effect is better. Figure 1 In the illustrated embodiment, the multifunctional sterilizer 100 includes two spray pipes 40. The number of the spray pipes 40 can be determined according to specific design requirements, and the power of the heating element 11 can be selected within the above range.

[0088] When one spray pipe 40 is provided in the working chamber 32, the volume of the heating chamber 31 is between 25 ml and 3500 ml; when multiple spray pipes 40 are provided in the working chamber 32, the volume of the heating chamber 31 is between 100 ml and 5000 ml. In this way, it is ensured that sufficient water can be filled in the heating chamber 31 to generate sufficient boiling water or steam to clean the milk bottle 91.

[0089] When one spray pipe 40 is provided in the working chamber 32, the volume of the heating chamber 31 is between 100 ml and 2000 ml; when multiple spray pipes 40 are provided in the working chamber 32, the volume of the heating chamber 31 is between 200 ml and 4000 ml. In this way, it is ensured that sufficient water can be filled in the heating chamber 31 to generate sufficient boiling water or steam to clean the milk bottle 91, and the heating chamber 31 does not occupy too much space.

[0090] In some embodiments, see Figure 1 , Figure 3 and Figure 8 The number of the spray pipes 40 is the same as the number of the spray channels 50, and the spray pipes 40 are connected to the corresponding spray channels 50. In this way, it can be ensured that each spray pipe 40 can obtain sufficient boiling water or steam, so that the spraying effect is better. Figure 1 In the illustrated embodiment, the number of the injection pipes 40 is 2, and accordingly, the number of the injection channels 50 is also 2. Of course, in other embodiments, the number of the injection pipes 40 is 1, 3, 4, 5, or 6, and the number of the injection channels 50 is correspondingly 1, 3, 4, 5, or 6. The above are just some examples and are not limited to the above examples.

[0091] In some other embodiments, the number of the injection channels 50 is less than the number of the injection pipes 40. Figures 9 to 12 The number of the injection pipes 40 is multiple, the number of the injection channel 50 is one, and the injection channel 50 is connected to the multiple injection pipes 40 through the connecting channel 60.

[0092] See also Fig. 9 , the number of the injection pipes 40 is two, and the number of the injection channel 50 is one. The two injection pipes 40 are connected by a connecting wall 61, and the connecting channel 60 is formed below the connecting wall 61. Both ends of the connecting channel 60 are respectively connected to the two injection pipes 40, and the bottom end of the connecting channel 60 is connected to the injection channel 50. The two injection pipes 40 are respectively protruded outward to form a supporting wall 46, and the two milk bottles 91 are respectively supported on the supporting wall 46 and the connecting wall 61.

[0093] See also Fig.10, the number of the injection pipes 40 is set to 4, and the number of the injection channel 50 is set to 1. The connecting channel 60 includes a first channel 66 connected to the two injection pipes 40 on the left and a second channel 67 connected to the two injection pipes 40 on the right. The first channel 66 includes a first section 661 connecting the two injection pipes 40 and a second section 662 connecting the first section 661 and the injection channel 50. The first section 661 extends horizontally, and the second section 662 extends vertically. The first channel 66 and the second channel 66 are symmetrically arranged, and will not be repeated here. The heights of the four injection pipes 40 can be the same or different.

[0094] The injection pipes 40 are arranged in multiple rows or around the injection channels 50, and the injection channels 50 are connected to the injection pipes 40 in each row through different connecting channels. Fig.11 The injection pipes 40 are arranged in two rows along the vertical direction, and each row has four injection pipes 40. The connecting channel connected to the four injection pipes 40 in the lower row is connected to the Fig. 9 The connecting channel 60 in the upper row has the same structure. Fig. 9 Compared with the connecting channel 60 in the embodiment, a vertical channel 63 extending in the up-down direction is added.

[0095] exist Figures 9 to 11 In the illustrated embodiment, the connecting channel 60 is integrally formed with the injection pipe 40 and supported by the upper cover 34 of the sewage chamber 33 , and the bottom wall 331 and the outer wall 332 of the sewage chamber 33 are integrally formed with the injection channel 50 .

[0096] See also Fig.12 The multifunctional disinfector 100 further includes a sewage receiving box 70, which is connected to the sewage chamber 33 through a pipe 75. During the cleaning and disinfection process, the sewage falling into the sewage chamber 33 can flow into the sewage receiving box 70 through the pipe 75, so that it is more convenient to handle the sewage and make the storage space cleaner and more sanitary. In the illustrated embodiment, one end of the pipe 75 is connected to the sewage receiving box 70, and the other end passes through the bottom wall 331 and is connected to the sewage chamber 33.

[0097] The multifunctional sterilizer 100 further includes a water tank 81 and a pump 82, wherein the pump 82 is used to transport the water in the water tank 81 to the heating chamber 31, and then heat the water in the heating chamber 31 through the heating element 11.
