Referring to fig. 1 to 6, a multi-purpose sterilizer 100 is used to perform cleaning and sterilization of a sterilization target. The sterilization target includes a cup, a bottle, a nipple, and the like, and is not limited thereto. In the embodiment shown in fig. 1, the sterilization target includes a feeding bottle 91 and a nipple 92. In the embodiment shown in fig. 2, the sterilization target includes a baby bottle 91. The multi-functional sterilizer 100 includes a housing 10, a cover 20, a first injection pipe 40, a second injection pipe 80, and a delivery pipe 90.

Referring to fig. 1, the base 10 includes a heating component 11, and the heating component 11 may be disposed on a bottom wall of the base 10 or disposed on a side wall of the base 10. In the illustrated embodiment, the heating element 11 is disposed on the bottom wall of the housing 10. The heating member 11 may be a brazing heating plate or an aluminum capacitor plate fixed to the bottom wall of the base 10, but is not limited thereto.

The cover 20 covers the base 10. The cover body 20 and the base body 10 jointly enclose to form an accommodating space, a heating cavity 31 and a working cavity 32 are arranged in the accommodating space, and the heating cavity 31 and the working cavity 32 are separated by a partition wall 331.

Referring to fig. 1 and 3, the heating cavity 31 is used for containing water, and the water in the heating cavity 31 is heated by the heating element 11. The first injection pipe 40 is disposed in the working chamber 32, and the first injection pipe 40 is communicated with the heating chamber 31 through an injection passage 50, and the injection passage 50 penetrates the partition wall 331 and is communicated with the heating chamber 31. A feeding bottle 91, a nipple 92 and other sterilization targets are placed in the working chamber 32 and sleeved outside the first injection pipe 40, and the first injection pipe 40 is used for cleaning the inner wall of the sterilization targets.

The second injection pipe 80 and the delivery pipe 90 are arranged in the working cavity 32, the delivery pipe 90 is communicated with the heating cavity 31, and the second injection pipe 80 is connected with the delivery pipe 90. The second spray pipe 80 is used to clean the outer wall of the sterilization target. The second injection pipe 80 may be attached to the delivery pipe 90, or may be integrally formed with the delivery pipe 90.

When the multifunctional sterilizer 100 is used for cleaning and/or sterilizing a sterilization target, the heating element 11 heats water in the heating cavity 31, the generated boiling water or steam enters the first injection pipe 40 through the injection passage 50 and then is injected on the inner wall of the sterilization target, fat, protein and the like remaining on the inner wall of the sterilization target are dissolved and flow down along the inner wall, and simultaneously, the generated boiling water or steam enters the second injection pipe 80 through the delivery pipe 90 and then is injected on the outer wall of the sterilization target, so that the outer wall of the sterilization target is cleaned and/or sterilized, and thus, the cleaning and sterilization of the sterilization target can be completed.

The partition wall 331 is integrally formed with the injection passage 50; alternatively, the partition wall 331 is integrally formed with the side wall of the heating cavity 31; alternatively, the partition wall 331 is a separate member, and the partition wall 331 is installed between the heating cavity 31 and the working cavity 32. In the illustrated embodiment, the partition wall 331 is integrally formed with the injection passage 50.

The injection passage 50 and the delivery pipe 90 respectively extend into the heating chamber 31. Referring to fig. 1, in use, the injection passage 50 and the lower end of the delivery pipe 90 are immersed in water in the heating chamber 31, so that a closed cavity 36 is formed between the liquid level in the heating chamber 31 and the partition wall 331. In the process of heating the water to boiling, a large amount of steam is generated from the water to enter the cavity 36, so that the pressure of the cavity 36 is rapidly increased, the pressure in the cavity 36 causes the boiling water to enter the first injection pipe 40 through the injection passage 50 and to be injected on the inner wall of the sterilization target through the first injection pipe 40, and the sewage generated after the spray washing flows down along the inner wall of the nursing bottle 91, and at the same time, the pressure in the cavity 36 causes the boiling water to enter the second injection pipe 80 through the delivery pipe 90 and to be injected on the outer wall of the sterilization target through the second injection pipe 80. Until the liquid level in the heating chamber 31 is lower than the lower ends of the side walls 51 of the injection passage 50 and the delivery pipe 90, the cavity 36 is not closed any more, and the boiled water can not be forced to enter the first injection pipe 40 and the delivery pipe 90, at this time, the steam generated by the water enters the first injection pipe 40 through the injection passage 50 and is injected on the inner wall of the feeding bottle 91 through the first injection pipe 40, and simultaneously, the steam enters the second injection pipe 80 through the delivery pipe 90 to further clean and sterilize the feeding bottle 91, and the steam is condensed into liquid on the inner wall and the outer wall of the feeding bottle 91 and is also discharged along the inner wall and the outer wall of the feeding bottle 91. It can be seen that, since the injection passage 50 and the delivery pipe 90 extend into the heating chamber 31, the pressure in the cavity 36 promotes the boiling water to clean and sterilize the sterilization target first, and then the generated steam cleans and sterilizes the sterilization target, so that the cleaning and sterilization effects are good.

The ratio of the height of the injection channel 50 extending into the heating cavity 31 to the height of the heating cavity 31 is between 1/20 and 19/20; and/or the ratio of the height of the delivery pipe 90 extending into the heating cavity 31 to the height of the heating cavity 31 is 1/20-19/20. Thus, when the multifunctional sterilizer 100 is used for cleaning and/or sterilizing the sterilization target, the sterilization target can be ensured to be sterilized by boiling water first, and then the sterilization target is sterilized by steam, so that the cleaning and sterilizing effects are further ensured.

The ratio of the height of the injection channel 50 extending into the heating cavity 31 to the height of the heating cavity 31 is between 2/10 and 7/10; and/or the ratio of the height of the delivery pipe 90 extending into the heating cavity 31 to the height of the heating cavity 31 is 2/10-7/10. Thus, when the multifunctional sterilizer 100 is used for cleaning and/or sterilizing the sterilization target, the sterilization target can be cleaned and/or sterilized by the boiling water and the steam in a better proportion in sequence, so that the cleaning and sterilizing effects can be optimal.

In the illustrated embodiment, the delivery tube 90 extends into the heating cavity 31 to a greater height than the ejection passage 50 extends into the heating cavity 31.

The height of the injection passage 50 extending into the heating chamber 31 is between 0 mm and 200 mm, so that it is possible to secure a sufficient time and amount of water for washing the feeding bottle 91. Preferably, the height of the injection channel 50 extending into the heating cavity 31 is between 5 mm and 80 mm. Thus, space can be saved, and sufficient time and water can be guaranteed to clean the feeding bottle 91.

The second injection pipe 80 comprises a mounting groove 81 matched with the top end of the conveying pipe 90, a first channel 94 is arranged at the top end of the conveying pipe 90, and a second channel 82 corresponding to the first channel 91 is arranged on the side wall of the mounting groove 81. Thus, by providing the first passage 94 and the second passage 82, the communication between the delivery pipe 90 and the second ejection pipe 80 is achieved.

The top end of the delivery pipe 90 is provided with a first sealing ring 96 to form a seal between the delivery pipe 90 and the side wall of the mounting groove 81. Thus, leakage of boiling water or steam from between the duct 90 and the side wall of the mounting groove 81 is prevented. A first seal 96 is located below the first and

second passages

94, 82. In the illustrated embodiment, the top end of the delivery tube 90 is provided with a groove 99, and the first sealing ring 96 is disposed in the groove 99 to limit the first sealing ring 96.

The pipe wall of the injection section 42 is inclined inwards from bottom to top, and the inclined angle is between 0 and 85 degrees. Because the pipe wall of the injection section 42 is inclined inwards from bottom to top, the boiling water or the steam entering the injection section 42 is pressed by the pipe wall, and can be injected to the inner wall of the feeding bottle 91 through the upper opening 421 or the first injection hole 422 with a large force, so that the spray washing effect is good.

Preferably, the tube wall of the injection section 42 is inclined at an angle ranging between 2 degrees and 30 degrees. So for boiling water or steam that get into injection section 42 can pass through upper shed 421 or first jet orifice 422 with sufficient dynamics and spray to the inner wall of feeding bottle 91, the spray rinsing effect is better, simultaneously, can guarantee again that first injection pipe 40 has higher height, and then can carry out abundant spray rinsing to not co-altitude feeding bottle 91.

The plurality of first injection holes 422 are evenly or unevenly distributed across the wall of the tube of the injector section 42. The area of the single first injection hole 422 is in the range of 0.13 mm square to 314 mm square, and in this range, the boiling water or steam entering the injection section 42 can be injected to the inner wall of the baby bottle 91 through the first injection hole 422 well, and at the same time, a certain strength of the injection section 42 can be ensured. Preferably, the area of the single first injection hole 422 is in the range of 7 mm square to 100 mm square, in which boiling water or steam entering the injection section 42 can be injected onto the inner wall of the feeding bottle 91 through the first injection hole 422 in a sufficient amount, while ensuring better strength of the injection section 42.

The area of the lower opening 55 of the injection passage 50 is larger than the area of the upper opening 421 of the first injection pipe 40. Thus, in the cleaning and disinfecting process, more boiling water or steam can enter the first injection pipe 40 through the lower opening 55, and the boiling water or steam sprayed from the upper opening 421 has a higher force. In one embodiment, the first injection pipe 40 is not provided with an upper opening, and only the first injection holes 422 are provided.

The upper opening 421 is a single through hole; alternatively, 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 holes can be in regular or irregular shapes such as circles, squares and polygons. In the illustrated embodiment, the upper opening 421 is a single through hole.

The lower opening 55 is a single through hole; alternatively, the lower opening 55 includes a plurality of through holes, and the area of the lower opening 55 is the sum of the areas of the plurality of through holes.
