Description

Technical Field

[0001] This utility model relates to the field of soymilk maker technology, specifically to a micro-pressure soymilk maker. Background Technology

[0002] Existing soy milk makers consist of a cup and a lid. The cup contains a cooking chamber, which is heated by a heating element to bring the soy milk to a boil. However, because most lids obstruct the opening of the cooking chamber, it remains open to the outside environment. Although the soy milk is boiling, the temperature does not exceed 100 degrees Celsius; due to geographical conditions and ambient temperature, the actual temperature is often below 100 degrees Celsius. Sealing the opening of the cooking chamber with the lid could allow the temperature to exceed 100 degrees Celsius, but the soy milk maker lacks a pressure relief mechanism, posing a safety hazard during use. Utility Model Content

[0003] The purpose of this invention is to provide a micro-pressure soymilk maker with a micro-pressure heating function in the cooking cavity.

[0004] The purpose of this utility model is achieved as follows.

[0005] A micro-pressure soymilk maker includes a cup body and a first lid. The cup body has a cooking chamber with a heating device at the bottom. The cooking chamber has an opening at the top of the cup body, and the first lid seals the opening. The first lid has a first pressure relief hole and a second pressure relief hole that communicate with the cooking chamber. The first pressure relief hole is sealed by a sealing plug. The first lid has a sealing device corresponding to the second pressure relief hole. The sealing device includes an elastic sealing element that disconnects the second pressure relief hole from the outside. When the pressure inside the cooking chamber exceeds the preset elastic force of the elastic sealing element, the airflow inside the cooking chamber flows to the outside through the first pressure relief hole, opening the elastic sealing element.

[0006] Furthermore, the sealing device includes a fastening device and the elastic sealing element. The fastening device fixes the elastic sealing element to the top of the first cover. The edge of the elastic sealing element abuts against the top surface of the first cover. The first pressure relief hole is located outside the outline of the edge of the elastic sealing element, and the second pressure relief hole is located within the outline of the edge of the elastic sealing element. The edge of the elastic sealing element has an upper recess near its edge, which causes the edge of the elastic sealing element to tend to abut against the top surface of the first cover. The sealing device is easy to install, and the upper recess ensures that the sealing element maintains its elastic tendency to abut against the first cover. The first and second pressure relief holes do not interfere with each other during venting.

[0007] Furthermore, the cross-section of the resilient seal is M-shaped. The upper concave portion is easy to form, and the shape of the resilient seal allows the edge of the seal to maintain an elastic tendency to abut against the first cover.

[0008] Furthermore, the second pressure relief hole is either an annular hole or a series of holes arranged in an annular shape, while the first pressure relief hole is located within the vertical projection range of the upper concave portion. The second pressure relief hole promptly releases gas from the cooking chamber, rapidly reducing the gas pressure within the cooking chamber.

[0009] Furthermore, the fastening device includes a bolt and a nut, and the resilient seal has a through hole in the center. The bolt passes through the through hole and is threadedly connected to the nut to clamp the resilient seal. The fastening device has a simple structure and is easy to assemble.

[0010] Furthermore, the bolt nut and the first cover are connected and fixed, with the top surface of the nut and the nut clamping the elastic seal. The top surface of the nut is higher than the top surface of the first cover, ensuring that the bottom surface of the central area of ​​the elastic seal does not contact the first cover. After the bolt and nut clamp the elastic seal, it prevents the edge of the elastic seal from lifting up, which could cause the second pressure relief hole to fail to seal.

[0011] Furthermore, the bottom edge of the nut abuts against the top of the upper recess, and the vertical projection of the nut's outline edge coincides with the second pressure relief hole. The nut also prevents the upper recess from warping upwards, avoiding excessive deformation of the elastic seal.

[0012] Furthermore, the top surface of the first cover is provided with an annular wall, the second pressure relief hole and sealing device are located inside the annular wall, and the first pressure relief hole and sealing plug are located outside the annular wall. The annular wall prevents gas from the second pressure relief hole from being directly discharged to the side, reducing the risk of burns. In addition, the annular wall keeps the elastic seal from being deformed or damaged by external forces, making it safer to use.

[0013] Furthermore, the top of the first cover is provided with a flip-up handle, from which the sealing plug extends. When the handle is rotated to abut against the top surface of the first cover, the sealing plug is inserted into the first pressure relief hole. The handle facilitates the removal and placement of the first cover. The sealing plug and handle are integrated, making it less likely to be lost, and also facilitating the alignment and insertion of the sealing plug into the first pressure relief hole.

[0014] Furthermore, it also includes a second lid, which screws onto the cup body. The first lid is placed within the cavity formed by the second lid and the cup body. The cup body is equipped with a microswitch, which is electrically connected to the heating device. After the second lid and cup body are screwed into place, the second lid activates the microswitch, causing the sealing plug to remain inserted into the first pressure relief hole. A venting gap is left between the second lid and the cup body, and / or the top of the second lid has a vent hole communicating with the cavity. Gas discharged from the second pressure relief hole is released through the venting gap and / or the vent hole. The soymilk maker can only operate after the second lid is installed, and the second lid seals the first pressure relief hole, making it safer to use.

[0015] This invention utilizes an elastic seal to seal the second pressure relief hole, allowing the gas pressure inside the cooking chamber to reach a higher level. This, in turn, enables the soy milk to be heated to over 100 degrees Celsius, improving its texture and flavor. The elastic seal deforms when the gas pressure in the cooking chamber exceeds a preset value, promptly releasing gas and ensuring the safe operation of the soy milk maker.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1, see Figure 1-7 As shown, a micro-pressure soy milk maker includes a cup body 1, a first lid body 2, and a second lid body 6.

[0025] The cup body 1 has a cooking cavity 10 inside, and a heating device 11 is provided at the bottom of the cooking cavity 10. A micro switch 12 is provided near the bottom of the cup body 1. The cup body 1 is also usually provided with a control device 13, and the control device 13, the micro switch 12 and the heating device 11 are electrically connected.

[0026] The cooking chamber 10 has an opening 14 at the top of the cup body 1, and the first cover 2 seals the opening 14. The first cover 2 has a first pressure relief hole 21 and a second pressure relief hole 22 that communicate with the cooking chamber 10. The first pressure relief hole 21 is sealed by a sealing plug 25. The first cover 2 has a sealing device 3 corresponding to the second pressure relief hole 22. The sealing device 3 includes an elastic sealing element 4. The elastic sealing element 4 disconnects the second pressure relief hole 22 from the outside. When the pressure inside the cooking chamber 10 exceeds the preset elastic force of the elastic sealing element 4, the airflow inside the cooking chamber 10 flows to the outside through the first pressure relief hole 21, pushing open the elastic sealing element 4.

[0027] Specifically, the sealing device 3 includes a fastening device 5 and the elastic sealing element 4. The fastening device 5 fixes the elastic sealing element 4 to the top of the first cover 2. The edge of the elastic sealing element 4 abuts against the top surface of the first cover 2. The first pressure relief hole 21 is located outside the outline of the edge of the elastic sealing element 4, and the second pressure relief hole 22 is located within the outline of the edge of the elastic sealing element 4. An upper recess 41 is provided near the edge of the elastic sealing element 4, which makes the edge of the elastic sealing element 4 tend to abut against the top surface of the first cover 2. In this embodiment, the cross-section of the elastic sealing element 4 is M-shaped. The first pressure relief hole 21 is an annular hole or a series of holes arranged in an annular shape. The second pressure relief hole 22 is located within the vertical projection range of the upper recess 41. The elastic sealing element 4 is made of high-temperature resistant silicone.

[0028] The fastening device 5 includes a bolt 51 and a nut 52. The elastic seal 4 has a through hole 42 at its center. The nut 50 of the bolt 51 is connected and fixed to the first cover 2. The bolt 51 passes upward through the through hole 42 and is threadedly connected to the nut 52 to clamp the elastic seal 4. The top surface of the nut 50 and the nut 52 clamp the elastic seal 4. The top surface of the nut 50 is higher than the top surface of the first cover 2, ensuring that the bottom surface of the central area of ​​the elastic seal 4 does not contact the first cover 2. The bottom edge of the nut 52 abuts against the top of the upper recess 41. The vertical projection of the nut 52's outline edge partially coincides with the second pressure relief hole 22.

[0029] The top surface of the first cover 2 is provided with an annular wall 23. The second pressure relief hole 22 and the sealing device 3 are located inside the annular wall 23, while the first pressure relief hole 21 and the sealing plug 25 are located outside the annular wall 23. The top of the first cover 2 is provided with a flip-up handle 24 outside the annular wall 23. The sealing plug 25 extends from one side of the handle 24. When the handle 24 is rotated to abut against the top surface of the first cover 2, the sealing plug 25 is inserted into the first pressure relief hole 21.

[0030] The second cover 6 and the cup body 1 are screwed together. The first cover 2 is placed inside the cavity 60 formed by the second cover 6 and the cup body 1. An exhaust gap 61 is left between the second cover 6 and the cup body 1. The top of the second cover 6 is provided with an exhaust hole 62 that communicates with the cavity 60.

[0031] In use, insert the first cover 2 into the opening 14, flatten the handle 24 and insert the sealing plug 25 into the first pressure relief hole 21, then screw the second cover 6 and the cup body 1 together, with the second cover 6 and the handle 24 abutting against each other, thus keeping the sealing plug 25 inserted into the second pressure relief hole 22. When the second cover 6 is in place, the bottom of the second cover 6 triggers the micro switch 12, at which point the control device 13 can activate the heating device 11. The heating device 11 heats the soy milk in the cooking chamber 10. Because the elastic seal 4 seals the second pressure relief hole 22, the soy milk in the cooking chamber 10 can be heated to over 100 degrees Celsius. When the gas pressure in the cooking chamber 10 exceeds the preset value, that is, when the pressure of the gas on the elastic seal 4 is greater than its elasticity, the edge of the elastic seal 4 elastically deforms upward, and the gas in the cooking chamber 10 is discharged into the cavity 60 through the second pressure relief hole 22, and finally discharged from the exhaust gap 61 and the exhaust hole 62, ensuring that the gas pressure in the cooking chamber 10 is maintained within a certain range. If the second cover 6 is unscrewed, the heating device 11 will stop heating.

[0032] After the soy milk is heated, unscrew the second cover 6. After the air pressure in the cooking chamber 10 drops, the elastic seal 4 continues to seal the second pressure relief hole 22. The user can flip the handle 24 to make the sealing plug 25 disengage from the first pressure relief hole 21. The cooking chamber 10 continues to release air. Finally, the user removes the first cover 2 through the handle 24.
