The beneficial effects of the invention are:

1. The glass cover is disposed between the upper bracket and the lower bracket, and the center of the glass cover is provided with a feeding port, so that the inner wall of the cup cover is made of a glass cover material, so that the user can clearly see the inside of the stirring cup through the cup cover. The working condition achieves a visual effect and enhances the customer's experience; and compared with the plastic material of the prior art, the glass cover is directly in contact with the slurry after the high speed rotation of the grinding knife, and is non-polluting and does not stain. The quality of the making slurry is improved, and the cleaning is convenient; by setting in the middle, the glass cover has good explosion-proof effect, and the installation is firm and is not easily crushed by external force, thereby improving the service life.

2. By fastening the upper and lower brackets and then clamping the glass cover, it is more convenient to install and fix the glass cover. It is only necessary to place the glass cover in the upper bracket from the bottom up, at this time outside the glass cover. The edge just touches and limits the lower bracket, and then the upper bracket is fixed by the lower bracket, so that the glass cover is naturally sandwiched and cannot move, and the structure is more reliable.

4. Fixing the anti-overflow electrode on the upper bracket solves the problem that the anti-overflow electrode is used as a metal member, which is difficult to directly connect with the glass cover, and the anti-overflow electrode also needs to electrically connect the conductive structure with the control panel, and the conductive structure is disposed on the glass. The cover is more difficult, but the glass cover serves as the top wall of the cup cover, which conflicts with the installation position of the overflow electrode. Therefore, the anti-overflow electrode is disposed on the upper bracket, which solves the above problems and can work independently without affecting each other. .

5. The anti-overflow electrode is arranged on the extension arm and is disposed through the glass cover, which solves the problem that the glass cover and the anti-overflow electrode are not directly installed, and the extension arm fixes the top end of the glass cover on the one hand, and fixes on the one hand. The overflow electrode allows the top end of the entire lid to accommodate both the glass cover and the anti-overflow electrode, both of which perform their respective functions in an optimal position without interference, thereby realizing a structure in which an anti-overflow electrode is provided on the cover glass.

6. Through the cooperation of the through hole and the anti-overflow electrode, the anti-overflow electrode is not directly fixed on the glass cover, which reduces the installation difficulty of the glass cover and the anti-overflow electrode, and the anti-overflow electrode and the extension arm are directly fixed, so that the sway is not Directly affected by the glass cover, the sealing between the anti-overflow electrode and the through hole avoids the problem of water ingress, and the sealing structure also serves to further fix the glass cover, thereby realizing the glass cover except for the lower clamping and lifting above. After the anti-overflow electrode positioning, the three-point positioning effect is the best, in the process of high-speed pulverization of the slurry, under the high-speed impact pressure, avoiding shaking and bursting.

7. By the cooperation of the mounting column and the anti-overflow sealing ring, the anti-overflow electrode is not directly in contact with the glass cover, because one of the glass material is a metal material and is a rigid material. During the high-speed pulverization process, the two collide with each other easily. A problem arises that easily causes the glass cover to burst and the anti-overflow electrode to wear. By installing the mounting column in the middle, the anti-overflow electrode is only fixed and fixed with the plastic mounting post, and the plastic mounting post is matched with the through hole of the glass cover, and the sealing ring is added, so that a reasonable soft installation gap is provided during the installation process. The structure is reliable.

8. Through the clamping relationship between the annular mounting portion and the glass cover and the feeding cylinder, not only the glass cover but also the feeding cylinder is slinged, and the feeding cylinder is integrally formed separately from the prior art. In addition, the cooperation of the feeding cylinder and the glass cover makes the inner space of the stirring cup cover a plastic-free space, further solving the problem of dyeing and sanitary problems, and further enhancing the user experience, especially in the heating environment. .

9. Through the setting of the double-layer cover, the fixing and installation of the inner layer of the stainless steel is facilitated, thereby ensuring that the pulverizing space inside the whole cup cover is made up of the stainless steel inner layer as the side wall, the glass cover as the top wall, and the feeding cylinder as the feeding channel. There is no plastic environment in the whole crushing space, the user is safer and more reliable, and easy to clean, and the installation structure is simple.

10. The upper end of the feeding cylinder is provided with a circular flange, and the annular flange is integrally formed with the feeding cylinder, which ensures that the top of the feeding cylinder is fixed and fixed, and the bottom participates in feeding and has the effect of spoiling, together with the slurry prepared at high speed. The reflow is formed, and the bottom is completely suspended, which further acts as a spoiler, achieving a hard mounting with the glass cover.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment 1:

A visible food processing machine, in this embodiment, the food processing machine is a broken wall cooking machine, as shown in FIG. 1 to FIG. 7, comprising a machine base 3 having a motor 1 and a main control board 2, and a main control board 2 The agitating cup 4 is disposed on the base 3, and the agitating cup 4 includes a cup body 5 and a cup cover 6. In this embodiment, the cup body 5 is a glass cup body 5, and the cup cover 6 is disposed on the cup. Above the body 5, the cup body 5 is provided with a handle 7, and the cup body 5 is provided with a pulverizing knife 8, and the motor 1 drives the pulverizing knife 8 to rotate by the cooperation of the upper and lower couplings 9, and the cup cover 6 includes an annular upper bracket 10 The annular lower bracket 11 and the glass cover 12, the upper bracket 10 and the lower bracket 11 are both made of plastic material, the glass cover 12 is disposed between the upper bracket 10 and the lower bracket 11, and the center of the glass cover 12 is provided with a feed port. 13, the feed port 13 is circular, the feed port 13 is provided with a feeding cover 14, the ratio of the diameter L1 of the feed port to the outer diameter L2 of the outer edge of the glass cover is 1/5 ≤ L1/L2 ≤ 1 /2, this embodiment L1/L2 is 1/3. The advantage of this arrangement is that the glass cover 12 is disposed between the upper bracket 10 and the lower bracket 11, and the center of the glass cover 12 is provided with a feed opening 13 such that the inner wall of the cover 6 is made of a glass cover 12, so that the user can The working state of the inside of the stirring cup 4 is clearly seen through the lid 6 to achieve a visual effect, and the customer's experience is enhanced; and the setting of the glass cover 12 is directly compared with the pulverizing knife compared with the plastic material of the prior art. 8 After the high-speed rotation, the slurry is contacted, no pollution and no dyeing, which improves the quality of the slurry and is easy to clean. By setting it in the middle, the glass cover 12 has good explosion-proof effect, and the installation is firm and is not easily crushed by external force, which improves Service life. When L1/L2 is less than 1/5, the overall size of the glass cover is too small, and the feed port is too small. Because of the high-speed pulverization process, the slurry will directly lie on the glass cover, so the size is too small to withstand high speed. Slurry impact; when L1/L2 is greater than 1/2, the size of the glass cover is too large, the feed port is too large, which exceeds half of the overall size of the glass cover, and cannot be installed with the upper and lower brackets, and the looseness coefficient becomes large, which is not conducive to Long-term use. In this range, the visual effect is just taken into consideration, and the effect of the glass cover being impacted by the high-speed slurry, that is, within the above range, the size of the feed port is reasonable, which ensures that the feed is complete and smooth, and that the slurry is not fed. The mouth is sprayed out and the strength of the glass cover is guaranteed.

The glass cover 12 is annular, and the outer edge of the cover glass 12 is interposed between the upper bracket 10 and the lower bracket 11, so that the arrangement is advantageous in that since the upper bracket 10 and the lower bracket 11 and the cover glass 12 are both annular structures, Only the outer edge of the mating installation ensures that the clamping of the outer edge is ensured, and the limit fixing in the axial direction is ensured, and the outer edge of the glass cover 12 which is most easily contacted has good anti-crush protection and avoids the hardness. In the process of high-speed slurry production, the impact of the high-speed slurry will push up the glass cover 12, and the glass cover 12 can be stably used in a high-speed environment.

The overflow electrode 29 also needs to electrically connect the conductive structure to the control board. The conductive structure is difficult to be disposed on the glass cover 12, but the glass cover 12 serves as the top wall of the cup cover 6, which conflicts with the installation position of the overflow electrode 29. The anti-overflow electrode 29 is disposed on the upper bracket 10, which solves the above problems, and can work independently of each other without affecting. When H is less than 1 cm, the overflow electrode 29 is too close to the glass cover 12. During the heating process, after the slurry hits the overflow electrode 29, the signal is fed back to the control panel, and the control panel controls the heating device to stop heating, but due to thermal inertia Existence, often the brakes are not in place, the slurry will rise to the glass cover 12 and come into contact, which is inconvenient to clean and there is a risk of spillage. When H is greater than 6cm, the distance between the two is too large, there is a possibility of anti-overflow in advance, which may lead to uncooked.

The horizontal distance between the overflow prevention electrode 29 and the feed cylinder 21 is A, which here refers to the distance between the overflow prevention electrode 29 and the outer wall of the feed cylinder 21, where 1 cm ≤ A ≤ 4 cm. In this embodiment, A is 2 cm. The advantage of this arrangement is that by defining the horizontal distance between the overflow prevention electrode 29 and the feed cylinder 21, when A is less than 1 cm, the distance is too close, and it is easy to hang the slurry between the two, thereby causing false triggering of the overflow prevention signal. . When A is greater than 4 cm, the distance between the two is too far, which will cause the anti-overflow electrode 29 to be too far from the center, and the signal trigger is insensitive.

The effect of the cover 12 realizes the positioning of the glass cover 12 in addition to the lower clamping, and the positioning of the overflow-proof electrode 29 after the upper lifting, the three-point positioning effect is optimal, and in the process of high-speed pulverization of the slurry, under high-speed impact pressure, Avoid shaking and bursting.

The lower end of the extension wall 18 is provided with a mounting post 31 extending downwardly. The mounting post 31 is integrally formed with the extension arm 18 and belongs to a part of the extension arm 18, which is made of plastic material. One end of the anti-overflow electrode 29 is embedded in the mounting post 31. The mounting post 31 is disposed through the through hole 30, and the overflow sealing ring 32 is disposed between the mounting post 31 and the through hole 30. The advantage of this arrangement is that the anti-overflow electrode 29 is not directly in contact with the glass cover 12 by the cooperation of the mounting post 31 and the anti-overflow sealing ring 32, because one of the glass material is a metal material, which is a rigid material and is pulverized at a high speed. In the process, collision between the two is prone to problems, which easily causes the glass cover 12 to burst and the anti-overflow electrode 29 to wear. By installing the mounting post 31 in between, the anti-overflow electrode 29 is only fixed and fixed to the plastic mounting post 31, and the plastic mounting post 31 is further engaged with the through hole 30 of the cover glass 12, and the sealing ring 32 is added, so that the mounting process is provided. Reasonable soft installation clearance and reliable structure.

The overflow sealing ring 32 includes a mounting portion 321 and an extending portion 322 located below the mounting portion 321 . The mounting portion 321 is annular, and the mounting portion 321 is sandwiched between the extending wall 18 and the cover glass 12 , and the extending portion 322 is from above. The mounting post 31 and the overflow preventing electrode 29 are covered, and the extending portion 322 seals the mounting post 31 and the through hole 30. The outer diameter of the mounting portion 321 is larger than the inner diameter of the through hole 30, and the detecting end of the anti-overflow electrode 29 is exposed. Covering of the overflow seal 32. The advantage of this arrangement is that the seal between the extension arm 18 and the cover glass 12, that is, the horizontal seal, the seal between the mounting post 31 and the through hole 30 is achieved by the specific shape of the anti-overflow seal 32. And the sealing in the vertical direction, the sealing between the anti-overflow electrode 29 and the mounting post 31, and only the detecting end is exposed, and the risk of contamination and hanging on the anti-overflow electrode 29 is avoided, so that the cleaning is simpler and the detection is more precise. .

The mounting bracket 33 is integrally formed with the mounting bracket 33. The conductive piece 34 is disposed under the mounting seat 33, and the conductive metal piece 35 is embedded in the extending arm 18. The conductive metal piece 35 is not exposed, and is completely embedded in the extending arm 18, and one end of the conductive metal piece 35 and the overflow preventing electrode 29, the other end of the conductive metal piece 35 is connected to the conductive piece 34. The handle 7 is provided with a conductive wire electrically connected to the main control board 2. After the cup cover 6 is mounted, the conductive piece 34 is connected with the conductive wire. The advantage of this arrangement is that the anti-overflow electrode 29 is connected to the control board through the conductive structure, so that the cup cover 6 can trigger the communication of the conductive signal after the cover is closed, as long as the anti-overflow can be realized in the working environment, and the misoperation is avoided. In addition, through the cooperation of the handle 7 and the mounting seat 33, the conductive structure utilizes the existing structure of the handle 7, which simplifies the distance of the conductive.

The bottom end of the overflow preventing electrode 29 is disposed lower than the bottom end of the upper bracket 10, and the bottom end of the overflow preventing electrode 29 is the detecting end. In this way, the position for facilitating the penetration is lower, and the upper bracket 10 is prevented from being affected by the thermal inertia during the heating process, and the slurry is directly in contact with the upper bracket 10.
