[0032] The head and the cup body of the soybean milk machine are connected in a manner different from the common soybean milk machine, the head of the soybean milk machine is provided with a downward extension, the extension and the lower cover of the head form an accommodating cavity, the cup body is provided with an insertion part, the insertion part of the cup body is inserted into the accommodating cavity, and the insertion part is fixed with the extension, that is, during the process of making soybean milk, the head and the cup body are fixed, and the head is stable and does not swing. The head swing will produce noise, and the user experience is poor; the head swing will cause the crushing device to be offset, which affects the crushing efficiency; the head is offset, the gap between the head and the cup body is uneven, during the working process of the soybean milk machine, the blade stirs the soybean milk, the soybean milk is turned up, and will be splashed out from the large gap, and the position with small gap has poor heat dissipation effect. The soybean milk machine of the embodiment fixes the head and the cup body, and well solves the problems of head swing and offset.

[0033] The soybean milk machine of the embodiment makes soybean milk in a relatively closed environment, in order to prevent difficult opening of the cover, a gas permeation hole is arranged on the lower cover of the head, the gas permeation hole is connected with the crushing cavity in the cup body, the head is further provided with a gas guide channel, one end of the gas guide channel communicates with the atmosphere, and the other end of the gas guide channel is connected with the gas permeation hole, that is, the gas guide channel and the gas permeation hole communicate the crushing cavity with the atmosphere, so as to balance the pressure difference between the inside and the outside, and the cover is convenient to open, thereby improving the user experience.

[0034] Specifically, the air vent 221 is provided with a shielding member, when the air pressure in the crushing cavity is less than the external air pressure, the air enters the crushing cavity after the shielding member is lifted by the air guide channel 26 and the air vent 221. The embodiment is a soybean milk machine with a stewing function, the air vent has a diameter of 1-2 mm, and hot air is discharged from the air vent during the soybean milk making process to prevent explosion caused by excessive pressure in the cup body. However, for the soybean milk machine with the stewing function, the hot air is discharged too fast during the soybean milk making process, which is not conducive to the realization of the stewing function. The cup body of the embodiment is a double-layer vacuum cup, water is heated in the vacuum cup, and the material is stewed before the soybean milk making operation. The shielding member is arranged outside the air vent, the air pressure in the cup body is higher than the external air pressure during the soybean milk making process, the hot air presses the shielding member tightly against the air vent, a small amount of hot air is discharged from the gap between the shielding member and the air vent, the hot air in the cup body is prevented from being discharged too fast from the air vent, and the stewing function is better realized. The soybean milk making is fast. After the temperature of the soybean milk in the cup body is reduced, the air pressure in the cup body is less than the external air pressure, the external air enters from the air guide channel and enters the crushing cavity after the shielding member is lifted by the air vent, and the cover is easily opened after the air pressure is balanced.

[0035] Specifically, the shielding member is a sealing member 27 that seals the air vent 221. The air vent is arranged on the lower cover, and the air guide channel is arranged on the machine head. In order to prevent water vapor from entering the machine head and affecting the working state of the components in the machine head, the shielding member is selected as a sealing member. The sealing member of the embodiment is a flexible silica gel member, which is sealed at the air vent. During the soybean milk making process, the pressure in the cup body is greater than the external air pressure, and the hot air in the cup body presses the sealing member tightly against the outside of the air vent to realize the sealing function. The high pressure in a short time can quickly make soybean milk. For some portable soybean milk machines, the soybean milk may enter the machine head from the air vent when the machine is moved. The presence of the sealing member can prevent the soybean milk from entering the machine head and damaging the internal components of the machine head.

[0036] Specifically, the sealing member 27 is arranged in the accommodating cavity, the sealing member 27 comprises an annular sealing portion 271 and a downwardly extending shielding portion 272 arranged at the inner side edge of the annular sealing portion 271, the annular sealing portion 271 is sleeved outside the lower cover 22, the top end of the insertion portion 11 presses the annular sealing portion 271 in the accommodating cavity to seal the crushing cavity, the air vent 221 is arranged at the side wall of the lower cover 22, and the shielding portion 272 is shielded outside the air vent 221.

[0040] The motor and the circuit board are arranged in the head, the working environment of the circuit board and the motor needs to be waterproof, the air guide channel is arranged in the head, water will enter the air guide channel when the head is cleaned, if the air guide channel is not isolated and sealed from the circuit board and the motor, water in the air guide channel will enter the motor and the circuit board, which is easy to damage the machine, so the air guide channel needs to be sealed. The annular rib is provided with a sealing gasket, the sealing gasket is inserted into the annular rib, a groove below the sealing gasket forms the second air guide channel, and the sealing gasket isolates the channel from the circuit board. The protrusion of the embodiment is a silica gel part, the third air guide channel is arranged in the silica gel part, the side wall of the silica gel part is open, air flows out of the second through hole, enters the third air guide channel, passes through the opening and then enters the crushing cavity, the opening in the side wall of the silica gel part is arranged correspondingly to the air permeable hole, and the silica gel part seals the inner side of the air permeable hole when the silica gel part is assembled in place. Therefore, a limiting plate needs to be arranged on the bottom end surface of the inner cover, which presses the silica gel part against the side wall of the lower cover.

[0041] Specifically, the insertion part 11 is recessed relative to the side wall of the cup body 1 to form a stepped surface, and the bottom end surface of the extension part 25 abuts against the stepped surface.

[0042] Specifically, the inner wall of the extension part 25 has an internal thread, the outer wall of the insertion part 11 has an external thread, and the cup body 1 and the head 2 are fixed by screwing. The extension part and the insertion part of the embodiment are screw-mounted, and in addition to the screw mounting mode, the rotation buckle mounting mode can also be used.

[0043] In addition, the sealing member can be a separate member for sealing the air passage hole only, and the sealing member mounting hole is arranged near the air passage hole. The sealing member is provided with a mounting protrusion and a shielding portion. The mounting protrusion is inserted into the mounting hole and fixed in the mounting hole. The fixing mode can be various. The simplest one is that the arrow-shaped hook is arranged at the end of the mounting protrusion. The rear end of the arrow-shaped hook is connected with the protrusion, and the diameter of the rear end is larger than that of the protrusion. Since the sealing member is a silica gel member, deformation occurs during mounting. The hole diameter of the mounting hole can be such that the arrow-shaped hook can pass through the mounting hole after deformation. The hook of the rear end of the arrow-shaped hook hooks the inner side of the mounting hole to fix the sealing member. The sealing member is also provided with a shielding portion. The shielding portion is arc-shaped and cooperates with the lower cover. When the sealing member is mounted in place, the shielding portion tightly abuts the outer side of the air passage hole to seal the air passage hole. The sealing member and the crushing cavity sealing member are separate structures, and the assembly is complex.

[0044] In addition, the upper cover has a top wall and a side wall. The extending portion is arranged at the lower end of the side wall and is integrally formed with the upper cover. The upper end of the lower cover extends into the upper cover and is fixed with the upper cover. Or the lower cover has an inward extending portion extending downward.

[0045] In addition, the upper cover is provided with a ventilation hole. The air guide channel is arranged between the upper cover and the lower cover. One end of the air guide channel is connected with the ventilation hole. The other end of the air guide channel is connected with the air passage hole. The simplest air guide channel is completely arranged in the machine head. The upper cover is provided with an opening. After the air enters the air guide channel, it directly passes through the air passage hole and enters the crushing cavity. However, in this scheme, the ventilation hole can be seen outside the machine head. If the ventilation hole is not sealed, water vapor will enter the air guide channel or even the machine head during cleaning.

[0046] The technical solutions of the embodiment except the sealing member structure are applicable to the second embodiment.

[0047] Embodiment two:

[0048] As shown in Figure 6 Another food processing machine is provided in the embodiment. The sealing member 27 is arranged in the accommodating cavity. The sealing member 27 includes an annular sealing portion 271 and an inward extending shielding portion 272 arranged at the inner side edge of the annular sealing portion 271.

Since the inner cover and the lower cover flange are attached, the two layers of holes can be connected without the air guide channel, the air hole is arranged opposite to the crushing cavity, and air directly enters the crushing cavity from the air hole.

[0050] The crushing cavity sealing piece and the air hole sealing piece of the embodiment are integrated, so that the sealing piece has an annular sealing part for sealing the crushing cavity and a shielding part for sealing the air hole. Since the air hole of the embodiment is arranged on the lower cover flange, the annular sealing part and the shielding part are located on the same horizontal plane and are both horizontally arranged. During pulping, the air pressure in the cup body is greater than the external air pressure, and the hot air presses the shielding part tightly on the flange of the lower cover to seal the crushing cavity. When the temperature of the slurry in the cup body decreases, the air pressure in the cup body is less than the external air pressure, external air enters from the air guide channel, and after passing through the air hole, the horizontally arranged shielding part is lifted downward, air enters the crushing cavity from the gap of the lifting, and the internal and external air pressures are balanced, and the cover is conveniently opened.

[0051] In the embodiment, the technical solutions other than the air hole position and the sealing piece structure are the same as those of the first embodiment.
