[0029] Figure 1 The vertical cross-sectional view of the fruit puree machine of the present invention is shown in FIG. Figure 1 A fruit puree machine includes a barrel 1, a fruit puree plate 6, a grinding plate 4, and a pressing rod 2. The fruit puree plate 6 is connected to the lower part of the barrel 1, and a mud cavity 61 is formed in the fruit puree plate 6. The grinding plate 4 is arranged between the barrel 1 and the fruit puree plate 6. In the vertical direction, the grinding surface of the grinding plate 4 faces the discharge port at the lower part of the barrel 1, and the grinding plate 4 is connected to a drive assembly 7. The pressing rod 2 is slidably arranged in the barrel 1. The barrel 1 is connected to the mud cavity 61, and the food 8 ground by the grinding plate 4 directly enters the mud cavity 61. When the pressing rod 2 is slid out upward, the food 8 can be placed in the barrel 1. When the pressing rod 2 is slid downward and squeezed, the pressing rod 2 and the grinding plate 4 clamp the food 8. When the fruit puree machine is working, the pressing rod 2 and the grinding plate 4 clamp the food 8. At this time, the grinding plate 4 rotates, and the grinding surface of the grinding plate 4 contacts and rubs the food 8. As the food 8 is crushed, the entire grinding surface of the grinding plate 4 can contact and grind the food 8, resulting in a large effective grinding area and high grinding efficiency. Moreover, the food 8 is squeezed by the pressing rod 2 and the grinding disc 4 and ground by the grinding disc 4 at the same time. The grinding disc 4 does not need to rotate at a very high speed to crush the food 8, thereby reducing noise pollution during the use of the fruit puree machine.

[0030] In this embodiment, a gap 3 is left between the grinding disc 4 and the barrel 1 , and the gap 3 connects the barrel 1 and the mud chamber 61 ; the ground food 8 is initially screened by the gap 3 and then enters the mud chamber 61 .

[0031] The specific structure of the scraper 5 and the grinding disc 4 is described below:

[0032] Figure 2 The exploded structure diagram of the grinding disc and scraper in the fruit puree machine of the present invention is shown. Figure 2 The grinding wheel 4 further includes a scraper 5, which is vertically arranged along the circumference of the grinding wheel 4 and is connected to the grinding wheel 4. The scraper 5 extends into the mud cavity 61, which is an annular cavity. When the grinding wheel 4 rotates to grind the food 8, the scraper 5 is driven by the grinding wheel 4 to rotate along the circumference of the annular mud cavity 61, thereby quickly discharging the ground food 8 from the mud cavity 61.

[0033] Furthermore, the scraper 5 is provided with a second retaining projection 51, which is provided with an extension 52. A retaining groove 42 is provided on the grinding disc 4. The shape of the retaining groove 42 corresponds to the surface shapes of the extension 52, the second retaining projection 51, and the scraper 5, and the retaining groove 42 accommodates the second retaining projection 51 and the extension 52. The extension 52 is angled relative to the length of the second retaining projection 51. When the scraper 5 is secured to the grinding disc 4, the retaining groove 42 and the second retaining projection 51 cooperate to restrict horizontal movement of the scraper 5 in a direction perpendicular to the second retaining projection 51. The retaining groove 42 and the extension 52 also cooperate to restrict horizontal movement of the scraper 5 in a direction perpendicular to the extension 52. Because of the angle between the extension 52 and the length of the second retaining projection 51, once the scraper 5 is secured to the grinding disc 4, movement of the scraper 5 is restricted in both intersecting directions within the horizontal plane, effectively securing the scraper 5 in the horizontal direction.

[0034] Furthermore, the grinding disc 4 comprises an upper disc body and a lower disc body, with a snap-fitting groove 42 defined in the grinding surface of the lower disc body. The snap-fitting groove 42 connects the side surfaces of the grinding disc 4 and the upper and lower end surfaces of the lower disc body. To assemble the scraper 5 onto the grinding disc 4, the upper and lower disc bodies are separated, and the second snap-fitting protrusion 51 is placed into the snap-fitting groove 42. The upper and lower disc bodies are then connected. At this point, the scraper 5 is also completely secured vertically, effectively securing it to the grinding disc 4.

[0035] In this embodiment, the upper surface of the grinding disc 4 is a grinding surface, and the grinding surface is provided with grinding teeth 41. The grinding teeth 41 increase the friction between the food 8 and the grinding disc 4. When the grinding disc 4 grinds the food 8, the grinding teeth 41 effectively crush the food 8 by contacting the processed food 8.

[0036] Preferably, the grinding teeth 41 are radially distributed with the center of the grinding disc 4 as the center of the circle. The grinding teeth 41 form multiple radial distribution lines, and the grinding teeth 41 on different distribution lines can repeatedly grind the food 8 to improve the grinding efficiency.

[0037] More preferably, each grinding tooth 41 is inclined toward the rotation direction of the grinding disc 4. Since the grinding teeth 41 contact the food 8 at a larger position, after the grinding teeth 41 are inclined, when the grinding teeth 41 contact the food 8, the grinding teeth 41 can form a better supporting force to prevent the grinding teeth 41 from breaking.

[0038] Further preferably, the grinding teeth 41 have a certain width along the radial distribution direction. The position where the grinding teeth 41 contact the food 8 has a certain width, which increases the contact area, allowing the grinding teeth 41 to grind a larger area of the food 8 and improve the grinding efficiency.

[0039] Preferably, two adjacent radially distributed grinding teeth 41 are staggered. The spacing between adjacent grinding teeth 41 facilitates the flow of ground food 8 to the edge of the grinding disc 4 under the action of the rotational force of the grinding disc 4. Staggering the grinding teeth 41 avoids dead corners in the grinding process.

[0040] The specific structure of the barrel 1 and the puree tray 6 is described below:

[0041] Figure 3 The figure shows the exploded structure of the fruit puree machine of the present invention with the driving assembly hidden. Figure 4 The following is a partial enlarged view of the fruit puree machine of the present invention at point A. Please refer to Figure 3 and Figure 4 A first engaging projection 12 extends circumferentially from the outer side of the barrel 1. A engaging notch 63 and a retaining groove 64 are provided on the inner side of the puree tray 6. The engaging notch 63 extends upward through the upper surface of the puree tray 6. The retaining groove 64 communicates with the engaging notch 63, but the upper portion of the retaining groove 64 is disconnected from the upper surface of the puree tray 6. The first engaging projection 12 engages within the retaining groove 64 along the engaging notch 63. The first engaging projection 12 engages within the retaining groove 64 along the engaging notch 63 and the retaining groove 64, securing the barrel 1 to the puree tray 6. This snap-fit connection facilitates assembly and disassembly, facilitating cleaning and maintenance of the puree machine.

[0042] Furthermore, a mud outlet 62 is formed on the side of the fruit puree tray 6, which communicates with the mud chamber 61. After the ground food 8 flows into the mud chamber 61 through the gap 3, it is discharged through the mud outlet 62 for easy collection. Furthermore, a filtering device, such as a filter, can be provided between the mud chamber 61 and the mud outlet 62 to remove large particles of food 8 and ensure the fineness of the food 8 flowing out of the mud outlet 62.

[0043] The specific structure of the press rod 2, the gap 3 and the drive assembly 7 is described below:

[0044] Please refer to Figure 1 and Figure 3 A guide groove 21 is provided on the pressing rod 2, and a guide flange 11 is provided in the barrel 1 to extend into the guide groove 21. The guide groove 21 and the guide flange 11 are arranged vertically. This limits the movement trajectory of the pressing rod 2 in the barrel 1, allowing the pressing rod 2 to move straight up and down in the barrel 1, thereby increasing the stability of the pressing rod 2 when moving.

[0045] Furthermore, the width of the gap 3 is between 1 and 5 mm. If the width of the gap 3 is too wide, large particles of food 8 may enter the mud chamber 61 along the gap 3, affecting the fineness of the ground food 8. If the width of the gap 3 is too small, the ground food 8 cannot flow into the mud chamber 61 properly, resulting in poor flow of the food 8. By controlling the width of the gap 3, the fineness of the ground food 8 can be controlled.

[0046] Furthermore, the drive assembly 7 includes a motor 73, a gearbox 71 connected to the motor 73, and a rotating shaft 72 connected to the gearbox 71. The rotating shaft 72 is vertically arranged and connected to the grinding disc 4. A housing 74 is also provided. The housing 74 is connected to the lower portion of the puree disc 6. The motor 73 and gearbox 71 are housed within the housing 74, which protects the motor 73 and gearbox 71. When grinding food 8, the motor 73 starts to output torque. The gearbox 71 amplifies the torque of the motor 73 and transmits this amplified torque to the grinding disc 4 via the rotating shaft 72, thereby driving the grinding disc 4 to rotate and grind the food 8.

[0047] The specific workflow of this utility model is as follows:

[0048] When grinding food 8, first, press rod 2 is moved upward and removed from barrel 1. Food 8 is placed inside barrel 1. Then, press rod 2 is aligned with barrel 1 and pressed downward until press rod 2 and grinding disc 4 clamp food 8. Then, motor 73 is started, and motor 73 starts to output torque. Gearbox 71 amplifies the torque of motor 73 and transmits this amplified torque to grinding disc 4 via shaft 72, driving grinding disc 4 to rotate. The rotating grinding disc 4 continuously grinds food 8 and drives scraper 5 to slide along mud chamber 61. During the grinding process, food 8, which has been ground into small particles, flows into mud chamber 61 along gap 3, is scraped by scraper 5, and discharged through mud outlet 62.

[0049] Thus, in the above-mentioned fruit puree machine, the entire grinding surface of the grinding disc 4 can contact and grind the food 8, resulting in a large effective grinding area and high grinding efficiency. In addition, the food 8 is squeezed by the pressing rod 2 and the grinding disc 4 at the same time, and the grinding disc 4 does not need to rotate too high to crush the food 8, thereby reducing noise pollution during the use of the fruit puree machine.

[0050] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
