Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with good sealing effect. Background Art

[0002] Existing food processing machines such as slicers and vegetable cutters usually include a main unit with a built-in motor, a knife disc connected to the motor, and a guide cylinder arranged below the main unit. In order to realize the processing of food materials, a feeding channel that runs through from top to bottom is usually set on the shell of the main unit. When processing food materials, the user places the food materials into the feeding channel. The food materials move downward along the feeding channel and fall into the guide cylinder after being processed by the knife disc, completing the food processing process. The existing shell usually includes an upper shell and a lower shell. The upper shell is formed with a feeding cylinder extending downward, and a plug-in slot that is plugged and matched with the feeding cylinder is provided on the lower shell. When the upper shell and the lower shell are docked, the feeding cylinder is inserted into the plug-in slot to form a feeding channel. However, when the user cleans the main unit, cleaning water and the like will enter the main unit through the gap between the feeding cylinder and the plug-in slot. Therefore, most manufacturers will set a sealing ring in the plug-in slot. When the feeding cylinder is inserted into the plug-in slot, the sealing ring is pressed to achieve sealing. However, due to the manufacturing tolerances of the upper and lower shells during manufacturing, and the longer downward extension of the feeding barrel, it will gradually deviate from the plug-in slot under the influence of the manufacturing tolerances, and during installation, the sealing ring is usually installed in the plug-in slot first and then the upper shell is installed in place. However, since the sealing ring is relatively thin, after assembly, the pressure holding effect of the bottom end of the feeding barrel on the sealing ring will be reduced, which will cause the sealing effect of the sealing ring to deteriorate or even fail. As a result, when processing food, the food will enter the installation cavity through the gap at the seal, resulting in residual dirt and odor in the installation cavity, and when the user cleans the main unit, the cleaning water will enter the installation cavity through the gap, causing the motor and other electrical components to become damp, short-circuit or even be damaged. Utility Model Content

[0003] The utility model aims to provide a food processing machine with good sealing effect, so as to solve the problem that the feeding cylinder in the existing food processing machine is not pressed firmly on the sealing ring in the plug-in groove, so that the cleaning water and the like can easily enter the main machine, causing the electrical components in the main machine to be damaged and dirt to accumulate.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good sealing effect, including a main unit with a built-in motor, a crushing device connected to the motor and a crushing cup arranged below the main unit, the main unit includes an outer shell, the outer shell is formed with a feeding channel running up and down and an installation cavity for accommodating the motor, the installation cavity is separated from the feeding channel, the outer shell includes an upper shell and a lower shell, the upper shell is provided with a first feeding cylinder extending downward, the lower shell is provided with a second feeding cylinder extending upward, the first feeding cylinder and the second feeding cylinder are plugged together to form a feeding channel, and a sealing sleeve is provided with a sealing member at the plug-in joint between the first feeding cylinder and the second feeding cylinder, and the sealing member is located in the installation cavity.

[0005] The present application forms a feeding channel that runs through the upper and lower parts of the shell, so that when the user processes the food, he can place the food into the feeding channel, and the food moves downward along the feeding channel and falls into the grinding cup after being processed by the crushing device, thereby completing the food processing process. At the same time, the upper shell is provided with a first feeding tube extending downward, and the lower shell is provided with a second feeding tube extending upward. The first feeding tube and the second feeding tube are plugged together to form a feeding channel. The sealing sleeve at the plug-in place of the first feeding tube and the second feeding tube is provided with a sealing member, and the sealing member is located in the installation cavity. Compared with the traditional method of only providing a feeding tube on the upper shell and providing a plug-in slot on the lower shell, the first feeding tube and the second feeding tube can greatly shorten the extension length of a single feeding tube under the same feeding channel length, so that the alignment of the first feeding tube and the second feeding tube is more accurate, thereby avoiding the situation that the feeding tube cannot be aligned with the plug-in slot due to production errors and the excessive extension of a single feeding tube, resulting in poor crimping effect on the seal after assembly, and ultimately resulting in poor sealing effect of the seal. At the same time, after the first feeding barrel and the second feeding barrel are accurately aligned and matched, the sealing sleeve is installed at the plug-in joint of the first feeding barrel and the second feeding barrel, which can directly realize the sealing of the plug-in joint of the two, and the sealing is exposed in the installation cavity, so that the assembler can intuitively observe whether the seal is installed in place during assembly, thereby ensuring the reliability of the installation position of the seal, thereby further improving the sealing effect of the seal on the plug-in joint of the two, avoiding the poor sealing effect of the seal, resulting in the food entering the installation cavity through the gap at the seal when processing the food, resulting in residual dirt and odor in the installation cavity, and ensuring the cleanliness of the main machine; at the same time, it is avoided that when the user cleans the main machine, the cleaning water enters the installation cavity through the gap, causing the motor and other electrical components to become damp and short-circuited or even damaged, thereby realizing the protection of electrical components, helping to extend the service life of the food processing machine and ensuring the smooth operation of the whole machine.

[0006] In a preferred implementation of a food processing machine with good sealing effect, a seepage gap connecting a feeding channel and an installation cavity is provided at the plug-in fitting place of the first feeding barrel and the second feeding barrel, and the seepage gap includes a seepage port located on one side of the feeding channel and a seepage port located on one side of the installation cavity, and a sealing member seals and blocks the outside of the seepage port.

[0007] By setting the seal to seal and shield the outside of the seepage outlet, when food or cleaning water seeps out through the seepage gap, the seal can directly block the cleaning water at the seepage outlet, further improving the sealing effect of the seal and preventing cleaning water from seeping into the installation cavity through the seepage gap.

[0008] In a preferred implementation of a food processing machine with good sealing effect, an axial positioning structure for limiting the axial movement of the sealing member is further provided between the first feeding cylinder and the second feeding cylinder and the sealing member.

[0009] By providing an axial positioning structure for limiting the axial movement of the seal between the first feeding barrel, the second feeding barrel and the seal, the seal can be axially limited by the positioning of the axial positioning structure when it is installed and in place, so that the seal can be fixed at the plug-in fitting place between the first feeding barrel and the second feeding barrel, avoiding the situation where the seal slides downward under the action of gravity after a long period of use, resulting in poor sealing effect or even failure, thereby further improving the sealing effect.

[0010] In a preferred implementation of a food processing machine with good sealing effect, a mounting groove opening laterally toward the mounting cavity is provided at the plug-in fitting between the first feeding barrel and the second feeding barrel, the sealing member is clamped in the mounting groove, and the axial positioning structure includes the mounting groove.

[0011] By providing an installation groove with a side opening toward the installation cavity at the plug-in fitting of the first feeding tube and the second feeding tube, the seal is clamped in the installation groove, and the axial positioning structure includes the installation groove, so that after the sealing rib is clamped in the installation groove, the top wall and the bottom wall of the installation groove can realize the axial limit of the seal, so that the seal can neither move upward nor downward, thereby improving the limit effect on the seal and ensuring the sealing effect of the seal. At the same time, the molding structure of the installation groove is simpler and easier to produce, which helps to reduce production costs and improve production efficiency.

[0012] In a preferred implementation of a food processing machine with good sealing effect, the first feeding barrel is provided with an upper positioning rib extending downward and an upper step portion located on the inner side of the upper positioning rib with the step surface facing downward, the second feeding barrel is provided with a lower positioning rib extending upward and a lower step portion located on the outer side of the lower positioning rib with the step surface facing upward, the lower positioning rib extends into the first feeding barrel and is fixedly abutted against the step surface of the upper step portion, and a mounting groove is formed between the upper positioning rib and the step surface of the lower step portion; or,

[0013] The outer side wall of the first feeding cylinder or the second feeding cylinder opens toward the installation cavity to form an installation groove.

[0014] By forming a mounting groove between the upper positioning rib and the step surface of the lower step portion, the mounting groove can be formed after the first feeding tube and the second feeding tube are plugged and matched, which further simplifies the forming method of the mounting groove and helps to further reduce production costs. At the same time, the sealing member abuts against the lower side of the upper positioning rib to cover the seepage outlet of the seepage gap, further improving the sealing effect of the sealing member and preventing cleaning water from seeping into the mounting cavity through the seepage gap.

[0015] By opening the outer wall of the first feeding barrel or the second feeding barrel toward the installation cavity to form an installation groove, when assembling the main machine, the assembler can first tighten the seal in the installation groove and then assemble the upper shell and the lower shell, thereby facilitating the assembly of the seal and helping to further improve the assembly efficiency.

[0017] By providing a fixed bracket fixedly connected to the first feeding barrel or the second feeding barrel, and the sealing member being clamped and fixed between the fixed bracket and the plug-in fitting portion of the first feeding barrel and the second feeding barrel, the sealing member can be clamped by the fixed bracket to improve the stability and reliability of the sealing member position, thereby avoiding the axial movement of the sealing member after long-term use, resulting in deterioration or even failure of the sealing effect, and further improving the sealing effect.

[0018] In a preferred implementation of a food processing machine with good sealing effect, a mounting groove opening laterally toward the mounting cavity is provided at the plug-in fitting place of the first feeding barrel and the second feeding barrel, and the fixed bracket includes a main body portion arranged around the outer periphery of the seal, and a limiting protrusion protruding radially inward from the inner side wall of the main body portion, and the limiting protrusion is clamped in the mounting groove.

[0022] By providing an outward-folded outer flange at the top of the seal, and overlapping the outer flange with the top of the fixed bracket, the fixed bracket can provide further axial support for the seal, thereby further avoiding the situation where the seal slides downward under the action of gravity after a long period of use, resulting in poor sealing effect or even failure, thereby further improving the sealing effect.

[0023] By providing a limiting groove on the side of the seal facing the installation cavity, and providing a convex rib that is plugged into and cooperates with the limiting groove in the main body of the fixed bracket, the fixed bracket can not only achieve radial pressure on the seal, but also provide circumferential limitation on the seal through the limiting cooperation of the limiting groove and the convex rib, thereby avoiding the situation where the seal slides circumferentially and its sealing effect deteriorates.

DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0043] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0044] like Figures 1 to 9 As shown, the utility model provides a food processing machine with good sealing effect, including a main body 1 with a built-in motor 4, a crushing device transmission connected to the motor 4 and a crushing cup 2 arranged below the main body 1, the main body 1 includes a shell, the shell is formed with a feeding channel 3 running through from top to bottom and a mounting cavity 5 for accommodating the motor 4, the mounting cavity 5 is separated from the feeding channel 3, the shell includes an upper shell 11 and a lower shell 12, the upper shell 11 is provided with a first feeding cylinder 111 extending downward, the lower shell 12 is provided with a second feeding cylinder 121 extending upward, the first feeding cylinder 111 and the second feeding cylinder 121 are plugged together to form the feeding channel 3, and a sealing sleeve is provided with a sealing member 6 at the plug-in fitting position of the first feeding cylinder 111 and the second feeding cylinder 121, and the sealing member 6 is located in the mounting cavity 5.

[0045] The present application forms a feeding channel 3 which runs through the outer shell from top to bottom, so that when processing food materials, the user places the food materials into the feeding channel 3, and the food materials move downward along the feeding channel 3 and fall into the grinding cup 2 after being processed by the grinding device, thereby completing the processing of the food materials. At the same time, the upper shell 11 is provided with a first feeding barrel 111 extending downward, and the lower shell 12 is provided with a second feeding barrel 121 extending upward. The first feeding barrel 111 and the second feeding barrel 121 are plugged together to form a feeding channel 3. The sealing sleeve at the plug-in connection between the first feeding barrel 111 and the second feeding barrel 121 is provided with a sealing member 6, and the sealing member 6 is located in the installation cavity 5. Compared with the traditional method of only providing a feeding barrel in the upper shell 11 and providing a plug-in groove in the lower shell 12, the first feeding barrel 111 and the second feeding barrel 121 can greatly shorten the extension length of a single feeding barrel under the same length of the feeding channel 3, so that the alignment of the first feeding barrel 111 and the second feeding barrel 121 is more precise, thereby avoiding the situation that the feeding barrel cannot be aligned with the plug-in groove due to production errors and excessive extension of a single feeding barrel, resulting in poor crimping effect of the seal 6 after assembly, and ultimately resulting in poor sealing effect of the seal 6. At the same time, after the first feeding barrel 111 and the second feeding barrel 121 are accurately aligned, the seal 6 is sleeved on the plug-in joint of the first feeding barrel 111 and the second feeding barrel 121, which can directly realize the sealing of the plug-in joint of the two, and the seal 6 is exposed in the installation cavity 5, so that the assembler can intuitively observe whether the seal 6 is installed in place during assembly, thereby ensuring the reliability of the installation position of the seal 6, thereby further improving the sealing effect of the seal 6 on the plug-in joint of the two, avoiding the poor sealing effect of the seal 6, resulting in the food entering the installation cavity 5 through the gap at the seal 6 during processing, resulting in residual dirt and odor in the installation cavity 5, and ensuring the cleanliness of the main unit 1; at the same time, it is avoided that when the user cleans the main unit 1, the cleaning water enters the installation cavity 5 through the gap, resulting in the motor 4 and other electrical components being damp, short-circuited or even damaged, thereby realizing the protection of the electrical components, helping to extend the service life of the food processor, and ensuring the smooth operation of the entire machine.

[0046] As a preferred embodiment of the present application, Figure 2 , Figure 3 As shown, the first feeding cylinder 111 and the second feeding cylinder 121 have a seepage gap connecting the feeding channel 3 and the installation cavity 5 at the plug-in fitting place. The seepage gap includes a seepage inlet located on one side of the feeding channel 3 and a seepage outlet located on one side of the installation cavity 5. The seal 6 seals and blocks the outside of the seepage outlet.

[0047] By setting the seal 6 to seal and shield the outside of the seepage outlet, when food or cleaning water seeps out through the seepage gap, the seal 6 directly blocks the cleaning water at the seepage outlet, further improving the sealing effect of the seal 6 and preventing cleaning water from seeping into the installation cavity 5 through the seepage gap.

[0048] As a preferred embodiment of the present application, Figure 8 , Fig. 9 As shown, an axial positioning structure for limiting the axial movement of the sealing member 6 is also provided between the first feeding cylinder 111 and the second feeding cylinder 121 and the sealing member 6 .

[0049] By providing an axial positioning structure for limiting the axial movement of the seal 6 between the first feeding barrel 111, the second feeding barrel 121 and the seal 6, the seal 6 can be axially limited by the positioning of the axial positioning structure when it is installed and in place, so that the seal 6 can be fixed at the plug-in fitting place between the first feeding barrel 111 and the second feeding barrel 121, thereby avoiding the situation in which the seal 6 slides downward under the action of gravity after a long period of use, resulting in a deterioration or even failure of the sealing effect, thereby further improving the sealing effect.

[0050] It should be noted that the present application does not specifically limit the axial positioning structure. As a preferred implementation of the present application, Fig. 9 As shown, a mounting groove 8 opening laterally toward the mounting cavity is provided at the plug-in fitting place between the first feeding barrel 111 and the second feeding barrel 121 , the sealing member 6 is clamped in the mounting groove 8 , and the axial positioning structure includes the mounting groove 8 .

[0051] By providing a mounting groove 8 with a lateral opening toward the mounting cavity at the plug-in fitting of the first feeding barrel 111 and the second feeding barrel 121, the seal 6 is clamped in the mounting groove 8, and the axial positioning structure includes the mounting groove 8, so that after the sealing rib 61 is clamped in the mounting groove 8, the top wall and the bottom wall of the mounting groove 8 can realize the axial limit of the seal 6, so that the seal 6 can neither move upward nor downward, thereby enhancing the limit effect on the seal 6 and ensuring the sealing effect of the seal 6. At the same time, the molding structure of the mounting groove 8 is simpler and easier to produce, which helps to reduce production costs and improve production efficiency.

[0052] It should be further explained that the present application does not specifically limit the forming method of the mounting groove 8 in this embodiment, and it can be any one of the following embodiments:

[0054] By forming the installation groove 8 between the upper positioning rib 1112 and the step surface of the lower step portion 1211, the first feeding tube 111 and the second feeding tube 121 can be plugged together to realize the molding of the installation groove 8, which further simplifies the molding method of the installation groove 8 and helps to further reduce the production cost. At the same time, the sealing member 6 abuts against the lower side of the upper positioning rib 1112 to cover the seepage outlet of the seepage gap, further improving the sealing effect of the sealing member 6, and preventing the cleaning water from seeping into the installation cavity 5 through the seepage gap.

[0055] Embodiment 2: In this embodiment, the outer wall of the first feeding cylinder 111 or the second feeding cylinder 121 opens toward the installation cavity 5 to form the installation groove 8.

[0056] By opening the outer wall of the first feeding barrel 111 or the second feeding barrel 121 toward the installation cavity 5 to form the installation groove 8, when the assembler assembles the main machine 1, the seal 6 can be first tightened in the installation groove 8 and then the upper shell 11 and the lower shell 12 can be assembled, thereby facilitating the assembly of the seal 6 and helping to further improve the assembly efficiency.

[0057] Of course, the axial positioning structure is not limited to the above-mentioned setting, and it can also be that a positioning rib extending outward is provided at the plug-in fitting of the first feeding barrel 111 and the second feeding barrel 121, and a positioning groove matching with the positioning rib is provided on the sealing member 6, and the axial positioning structure includes the positioning rib and the positioning groove. It can also be that two circles of convex ribs extending outward are provided at the plug-in fitting of the first feeding barrel 111 and the second feeding barrel 121, and the sealing member 6 is clamped between the two circles of convex ribs.

[0059] By providing a fixed bracket 7 fixedly connected to the first feeding barrel 111 or the second feeding barrel 121, and the sealing member 6 is clamped and fixed between the fixed bracket 7 and the plug-in fitting portion between the first feeding barrel 111 and the second feeding barrel 121, the sealing member 6 can be clamped by the fixed bracket 7 to improve the stability and reliability of the position of the sealing member 6, thereby avoiding the axial movement of the sealing member 6 after long-term use, which may lead to deterioration or even failure of the sealing effect, and further improving the sealing effect.

[0060] It should be noted that the present application does not specifically limit the structure of the fixing bracket 7. As a preferred embodiment of the present application, Figure 3 As shown, a mounting groove 8 opening laterally toward the mounting cavity 5 is provided at the plug-in fitting place of the first feeding barrel 111 and the second feeding barrel 121, and the fixed bracket 7 includes a main body portion 71 arranged around the outer periphery of the sealing member 6, and a limiting protrusion 72 protruding radially inward from the inner side wall of the main body portion 71, and the limiting protrusion 72 is clamped in the mounting groove 8.

The limiting protrusion 72 is snapped into the installation groove 8, so that the fixed bracket 7 is fixedly connected with the first feeding barrel 111 or the second feeding barrel 121 through the snap-fitting of the limiting protrusion 72 and the installation groove 8, thereby ensuring the fixing effect of the fixed bracket 7. At the same time, the main body part 71 realizes radial pressure holding of the sealing member 6, so that the sealing member 6 can be firmly clamped and fixed between the fixed bracket 7 and the plug-in fitting place between the first feeding barrel 111 and the second feeding barrel 121, thereby further improving the position stability of the sealing member 6, thereby further ensuring the sealing effect of the sealing member 6. Of course, the fixing bracket 7 is not limited to the above-mentioned fixing method of directly clamping the limiting protrusion 72 in the installation groove 8, and it can also be fixed in the installation groove by connecting parts such as screws, etc., which will not be repeated here.

[0062] As a preferred embodiment of this embodiment, Figure 5 , Figure 6 As shown, the top of the sealing member 6 is provided with an outwardly folded outer edge 62 , and the outer edge 62 is overlapped with the top of the fixing bracket 7 .

[0063] By providing an outwardly folded outer flange 62 at the top of the seal 6, the outer flange 62 overlaps the top of the fixed bracket 7, so that the fixed bracket 7 can provide further axial support for the seal 6, thereby further avoiding the seal 6 sliding downward under the action of gravity after a long period of use, resulting in a deterioration or even failure of the sealing effect, thereby further improving the sealing effect.

[0064] As a preferred embodiment of this embodiment, Figure 8 As shown, a limiting groove 63 is further provided on the side of the sealing member 6 facing the installation cavity 5 , and a convex rib 73 which is plugged and matched with the limiting groove 63 is provided in the body portion 71 of the fixing bracket 7 .

[0065] By providing a limiting groove 63 on the side of the sealing member 6 facing the mounting cavity 5, and providing a convex rib 73 which is plugged into and cooperates with the limiting groove 63 in the main body 71 of the fixing bracket 7, the fixing bracket 7 can not only realize radial pressing of the sealing member 6, but also provide circumferential limiting of the sealing member 6 through the limiting cooperation of the limiting groove 63 and the convex rib 73, thereby avoiding the situation where the sealing member 6 slides circumferentially and its sealing effect deteriorates.

[0066] As a preferred embodiment of this embodiment, Figure 4 , Figure 7 As shown, the bottom wall of the lower shell 12 is further provided with a reinforcing rib 123 extending upward, and the bottom of the fixing bracket 7 is provided with a positioning hole 74 cooperating with the reinforcing rib 123 .

[0067] By providing an upwardly extending reinforcing rib 123 on the bottom wall of the lower shell 12, and providing a positioning hole 74 cooperating with the reinforcing rib 123 at the bottom of the fixed bracket 7, the lower shell 12 can achieve structural strength reinforcement through the reinforcing rib 123, and can also achieve axial support for the fixed bracket 7 through the cooperation between the positioning hole 74 and the reinforcing rib 123, thereby improving the position stability of the fixed bracket 7 and ensuring the fixing and clamping effect of the fixed bracket 7 on the seal 6.

[0068] It should be noted that the present application does not specifically limit the location of the reinforcing rib 123. As a preferred embodiment of the present application, Figure 4 As shown, the bottom wall of the lower shell 12 is also provided with a reinforcing rib 123 extending upward, and a fixing column 122 for fixing the upper shell 11 and the lower shell 12 together, and the reinforcing rib 123 is connected between the fixing column 122 and the second feeding barrel 121 .

[0069] By setting the reinforcing rib 123 to be connected between the fixed column 122 and the second feeding barrel 121, not only the structural strength of the entire lower shell 12 can be improved, but also the structural stability of the fixed column 122 and the second feeding barrel 121 can be improved, thereby avoiding relative displacement during assembly, which may lead to a deterioration in the sealing effect of the seal 6.

[0070] Of course, the fixed bracket 7 is not limited to the above-mentioned settings, it can also include a first bracket and a second bracket, and one end of the first bracket is hinged to one end of the second bracket, and the other end is provided with a clamping part. After the seal 6 is installed in place, the first bracket and the second bracket are buckled on the outside of the seal 6 to fix the seal 6.

[0071] As a preferred embodiment of the present application, Figure 3As shown, a plurality of sealing ribs 61 arranged axially at intervals are provided on the side of the sealing member 6 facing the feeding channel 3 .

[0072] By providing a plurality of axially spaced sealing ribs 61 on the side of the seal 6 facing the feeding channel 3, the seal 6 is able to abut against the outer walls of the first feeding barrel 111 and the second feeding barrel 121 through the sealing ribs 61, so that a multi-step-shaped sealing channel is formed therebetween, thereby effectively improving the sealing effect of the seal 6 and further preventing cleaning water from overflowing into the installation cavity 5 through the gap.

[0073] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.
