Description

Technical Field

[0001] This utility model relates to the field of food processing machine technology, and in particular to a food processing machine. Background Technology

[0002] Existing food processing machines typically include a main unit and a mixing cup assembly. The main unit contains a circuit board and a motor. The mixing cup assembly includes a cup base, a cup body, and a cup lid. The cup lid and the cup body together form a grinding chamber. The cup body contains a grinding blade. The motor in the main unit drives the grinding blade to rotate, thereby grinding the food in the grinding chamber. This is the transmission of power. The power transmission is generally achieved by having a first coupler in the cup base and a second coupler in the main unit. The first coupler and the second coupler are coupled to supply power upwards.

[0003] Application number CN202223609189.3, entitled "A Reliable Food Processing Machine," discloses a main unit with a lower coupler, a cup assembly with an upper coupler that is plugged into and coupled to the lower coupler, and a mounting position on the cup bottom cover exposing the plug-in portion of the upper coupler. The upper coupler is fixed to the cup bottom cover by a mounting base, which has an annular seat for embedding the upper coupler. The seat and the cup bottom cover are connected by a first positioning component. However, the technical problem with this solution is that since the food processing machine has the function of crushing and processing hot drinks, heating components such as heating tubes are inevitably installed at the bottom of the cup base. When the cup bottom cover is closed and placed at the bottom of the cup base, the mounting base for mounting the upper coupler on the cup bottom cover has an annular seat. The through-hole in the middle of the annular seat is used to embed the upper coupler. The upper coupler directly passes through the through-hole in the middle of the annular seat, which may lead to direct contact or excessively close proximity with the heating components at the bottom of the cup base. The heating components transfer heat to the upper coupler, which will greatly shorten the service life of the upper coupler.

[0004] The above-disclosed technical solutions all have the following technical problems: the distance between the heating component and the upper coupler is too close, which greatly shortens the service life of the upper coupler. Utility Model Content

[0005] The purpose of this invention is to provide a food processing machine to solve the problem that the distance between the heating element and the upper coupler is too close, which leads to a significant reduction in the service life of the upper coupler.

[0006] To solve the above-mentioned technical problems, this utility model provides a food processing machine, comprising:

[0007] Cup body;

[0008] A heating element is located at the bottom of the cup body;

[0009] A first coupler is disposed at the bottom of the heating element;

[0010] A bracket is fixed to the bottom of the cup body, axially positioned between the heating element and the first coupler, and fixedly connected to the first coupler.

[0011] The projection of the first coupler in the horizontal plane is located within the bracket, and the projection of the bracket in the horizontal plane coincides with a portion of the heating element.

[0012] Preferably, the food processing machine further includes a cup base covering the bottom of the cup body, the bracket is clamped and fixed between the cup body and the cup base, and the cup base has an opening at its lower end to avoid the first coupler.

[0013] Preferably, the bottom of the cup body is provided with a fixing post, the bracket includes a mounting part sleeved on the fixing post, and the locking member passes through the cup base and the mounting part in sequence and is locked and connected to the fixing post.

[0014] Preferably, the bracket includes a mounting portion fixed to the bottom of the cup body and an extension portion fixedly connected to the mounting portion, the extension portion being axially disposed between the heating element and the first coupler.

[0015] Preferably, the extension has a recessed portion extending toward the heating element, and the recessed portion is correspondingly located on the upper part of the first coupler.

[0016] Preferably, the extension further has a downwardly protruding bulge, which is fitted to the upper part of the first coupler.

[0017] Preferably, the bracket has a downwardly extending positioning post, and the first coupler has mounting holes on both sides for fixing to the positioning post.

[0018] Preferably, the side of the positioning post extends axially and is provided with a limiting surface.

[0019] Preferably, the bracket further has a downwardly extending snap-fit ​​portion, which is snapped onto both sides of the first coupler.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model provides a food processing machine, which consists of a heating element disposed at the bottom of a cup body, a first coupler disposed at the bottom of the heating element, and a bracket fixed to the bottom of the cup body, axially disposed between the heating element and the first coupler, and fixedly connected to the first coupler. Since the heating element, bracket, and first coupler are stacked sequentially from top to bottom, the projection of part of the heating element on the horizontal plane coincides with the bracket, and the projection of part of the bracket on the horizontal plane coincides with the first coupler. The overlapping areas of the projections of the heating element, bracket, and first coupler on the horizontal plane significantly reduce the radial dimension of the cup body. Furthermore, the bracket isolates the heating element and the first coupler, effectively preventing direct contact or excessive close proximity between them, thus preventing the heating element from transferring heat to the first coupler and extending the service life of the first coupler.

[0022] 2. Since the projection of the first coupler on the horizontal plane is located inside the bracket, the upper surface of the first coupler is not exposed to the bracket. The upper surface of the first coupler and the bottom of the heating element are completely isolated by the bracket, effectively preventing the first coupler from being affected by the heat of the heating element due to being exposed to the bracket, thus further extending the service life of the first coupler. Moreover, the projection of the bracket on the horizontal plane coincides with part of the heating element. The bracket is stacked on the heating element along the axial direction, realizing the miniaturization of the radial dimension of the cup body. Furthermore, the size of the projection of the bracket on the horizontal plane only needs to ensure that the upper surface of the first coupler is not exposed. Therefore, the projection area of ​​the bracket on the horizontal plane can be smaller than the cross-section of the heating element. Only the projection of the bracket on the horizontal plane coincides with part of the heating element, so that the remaining space at the bottom of the cup body can be used to install other components, thereby improving the space utilization rate at the bottom of the cup body and making the structure more compact.

[0023] 3. The cup base, which is fitted over the bottom of the cup body, is locked and fixed to the bottom of the cup body from top to bottom, thereby clamping and fixing the bracket between the cup body and the cup base. This prevents the bracket from undergoing relative displacement in the radial direction, which would affect the reliability of the first coupler installed on the bracket. It also ensures that the bracket can stably isolate the first coupler and the heating element during use. Only one locking and fixing structure is used to fix the cup body, the bracket, and the cup base, simplifying the installation structure. The cup base has an opening at the lower end that avoids the first coupler. The first coupler passes through the opening and is inserted and coupled to the second coupler from top to bottom.

[0024] 4. Based on the fact that the extension has a recessed position extending towards the heating element, the recessed position is correspondingly located on the upper part of the first coupler, and the first coupler is located above the recessed position. On the one hand, it prevents the heat from the heating element from being transferred to the bracket. If the bracket is directly attached to the first coupler, the bracket will easily transfer heat to the first coupler when it is heated. The recessed position reduces the contact area between the bracket and the first coupler and provides sufficient heat dissipation space between the bracket and the first coupler, avoiding the rapid conduction of heat from the bracket to the first coupler, and further extending the service life of the first coupler. On the other hand, the wires led out from the first coupler are electrically connected to the components installed at the bottom of the cup body through the recessed position. The recessed position allows the wires led out from the first coupler to avoid the heating element. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please see Figures 1-5 The present invention provides a food processing machine including a cup body 1, a main unit, a heating element 2, a first coupler 3, a second coupler, a support 4, and a cup base 5. The main unit is located at the bottom of the cup base 5. The motor in the main unit drives the pulverizing blade in the cup body 1 to rotate and cut the material. The second coupler is located in the main unit. The first coupler 3 and the second coupler are inserted and coupled vertically.

[0035] Heating element 2 is disposed at the bottom of the cup body 1 and can be a heating tube or other component used to heat the slurry; first coupler 3 is disposed at the bottom of heating element 2; bracket 4 is fixed to the bottom of the cup body 1, is disposed axially between heating element 2 and first coupler 3, and is fixedly connected to first coupler 3.

[0036] It is understandable that the heating element 2, the support 4, and the first coupler 3 are stacked sequentially from top to bottom. This means that the projection of part of the heating element 2 onto the horizontal plane coincides with the support 4, and the projection of part of the support 4 onto the horizontal plane coincides with the first coupler 3. The projections of the heating element 2, the support 4, and the first coupler 3 onto the horizontal plane partially overlap, significantly reducing the radial dimension of the cup body 1. Secondly, the support 4, acting as an isolation between the heating element 2 and the first coupler 3, effectively prevents direct contact or excessive close proximity between them, preventing the heating element 2 from transferring heat to the first coupler 3, thereby extending the service life of the first coupler 3.

[0037] As a preferred embodiment, such as Figure 4 As shown, the projection of the first coupler 3 on the horizontal plane is located within the bracket 4, so that the upper surface of the first coupler 3 is not exposed to the bracket 4. The upper surface of the first coupler 3 and the bottom of the heating element 2 are completely isolated by the bracket 4, effectively preventing the first coupler 3 from being affected by the heat of the heating element 2 due to being exposed to the bracket 4, and further extending the service life of the first coupler 3. The projection of the bracket 4 on the horizontal plane coincides with part of the heating element 2. The bracket 4 is stacked on the heating element 2 along the axial direction, realizing the miniaturization of the radial dimension of the cup body 1. Furthermore, the size of the projection of the bracket 4 on the horizontal plane only needs to ensure that the upper surface of the first coupler 3 is not exposed. Therefore, the projection area of ​​the bracket 4 on the horizontal plane can be smaller than the cross-section of the heating element 2. Only the projection of the bracket 4 on the horizontal plane coincides with part of the heating element 2, so that the remaining space at the bottom of the cup body 1 can be used to install other components, thereby improving the space utilization rate at the bottom of the cup body 1 and making the structure more compact.

[0038] Of course, in other embodiments, a portion of the first coupler 3 may be projected onto the horizontal plane within the bracket 4, while another portion of the first coupler 3 may extend radially upwards outside the bracket 4.

[0039] For mounting bracket 4, such as Figure 1 , Figure 3 As shown, the food processing machine also includes a cup base 5 covering the bottom of the cup body 1. The cup base 5 is locked and fixed to the bottom of the cup body 1 from top to bottom to clamp and fix the bracket 4 between the cup body 1 and the cup base 5, preventing the bracket 4 from having relative displacement in the radial direction, which would affect the reliability of the first coupler 3 installed on the bracket 4. It also ensures that the bracket 4 can stably isolate the first coupler 3 and the heating element 2 during use. Only one locking and fixing structure is used to fix the cup body 1, the bracket 4 and the cup base 5, which simplifies the installation structure. The cup base 5 has an opening 51 at its lower end to avoid the first coupler 3. The first coupler 3 passes through the opening 51 and is inserted and coupled to the second coupler from top to bottom.

[0040] Specifically, in order to lock the cup base 5 and the bottom of the cup body 1 together, the bottom of the cup body 1 is provided with a fixing post 11, and the bracket 4 includes a mounting part 41 sleeved on the fixing post 11. The mounting part 41 can be a mounting sleeve sleeved on the fixing post 11. The locking member passes through the cup base 5 and the mounting part 41 in sequence and is locked and connected to the fixing post 11, thereby clamping and fixing the bracket 4 between the cup body 1 and the cup base 5.

[0041] The specific structure of support 4 is as follows: Figure 2 As shown, the bracket 4 includes a mounting portion 41 fixed to the bottom of the cup body 1, and an extension portion 42 fixedly connected to the mounting portion 41. The extension portion 42 is axially disposed between the heating element 2 and the first coupler 3. It can be understood that the inner surface of the extension portion 42 is arc-shaped, the heating element 2 is disc-shaped, and the extension shape of the extension portion 42 in the horizontal plane matches the shape of the heating element 2. There are two mounting portions 41, which are respectively located on both sides of the extension portion 42 circumferentially. When the mounting portions 41 are sleeved on the fixing post 11 and locked, the stability of fixing the extension portion 42 is improved.

[0042] Specifically, the extension 42 has a recessed portion 421 extending towards the heating element 2, and the recessed portion 421 is correspondingly located on the upper part of the first coupler 3. It can be understood that the first coupler 3 is located above the recessed portion 421 to prevent heat from the heating element 2 from being transferred to the support 4. If the support 4 is directly attached to the first coupler 3, the heat from the support 4 can easily be transferred to the first coupler 3. The recessed portion 421 reduces the contact area between the support 4 and the first coupler 3 and provides sufficient heat dissipation space between the support 4 and the first coupler 3, preventing the heat from the support 4 from being quickly conducted to the first coupler 3, and further extending the service life of the first coupler 3. On the other hand, the wires leading out from the first coupler 3 are electrically connected to the components installed at the bottom of the cup body 1 through the recessed portion 421. The recessed portion 421 allows the wires leading out from the first coupler 3 to avoid the heating element 2.

[0043] Furthermore, the extension 42 has downwardly protruding bulges 422, which are fitted against the upper part of the first coupler 3. In this embodiment, four bulges 422 are provided, but any number can be used. The bulges 422 are provided on both sides of the recess 421, with two bulges 422 on each side of the recess 421. By providing the bulges 422, the contact area between the first coupler 3 and the bracket 4 is further reduced, preventing the heat received by the bracket 4 from being quickly conducted to the first coupler 3, effectively extending the service life of the first coupler 3.

[0044] To achieve the fixation of the first coupler 3 on the bracket 4, such as Figures 2-5 As shown, the bracket 4 has a downwardly extending positioning post 43. The first coupler 3 has mounting holes 31 on both sides that are sleeved and fixed to the positioning post 43. The first coupler 3 has lugs on both sides, and mounting holes 31 are provided on the lugs. The mounting holes 31 and the positioning post 43 cooperate to restrict the horizontal displacement of the first coupler 3, so that the first coupler 3 can be stably installed on the bracket 4, and the upper end face of the first coupler 3 is not exposed to the bracket 4 and affected by the heat generated by the heating element 2.

[0045] As a preferred embodiment, such as Figure 2 As shown, since the positioning post 43 is approximately cylindrical, a limiting surface 431 is provided on the side of the positioning post 43 extending axially. The edge of the limiting surface 431 abuts against the inner wall of the mounting hole 31 to prevent the positioning hole from shifting slightly, thereby avoiding relative displacement and deflection between the first coupler 3 and the bracket 4.

[0046] Furthermore, such as Figure 5As shown, the bracket 4 also has a downwardly extending snap-fit ​​portion 44, which is snapped onto both sides of the first coupler 3; the snap-fit ​​portion 44 can be a hook, which is snapped onto the upper end face of the lug, restricting the relative displacement of the first coupler 3 in the axial direction, and further improving the installation stability of the first coupler 3 on the bracket 4.

[0047] In addition to the preferred embodiments described above, the technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that the combination of multiple technical solutions in any one embodiment, as well as the combination of technical solutions in any one embodiment with technical solutions in one or more other embodiments, are within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
