Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, in particular to a head assembly and a cooking machine. Background Art

[0002] A cooking machine is a common household appliance in people's lives. The cooking machine has multiple functions such as making soybean milk, squeezing fruit juice, and making minced meat. The cooking machine of the related art includes a cup body and a head assembly installed on the cup body. The head assembly includes a head seat, a head cover, and a driving component (in some cases, electronic components such as a control board are also included).

[0003] However, technicians have found that: in the related art, the sealing effect of the head of the cooking machine is poor, and the water vapor or liquid in the cup body easily enters the inside of the head assembly, resulting in the failure of the driving component (in some cases, the electronic components such as the control board also malfunction), frequent use failures of the cooking machine, and poor user experience. Summary of the Utility Model

[0004] The utility model provides a head assembly and a cooking machine. The head assembly has a good sealing effect, reduces the failure rate of the cooking machine, and improves the user experience.

[0005] The technical solution adopted by the utility model is as follows:

[0006] According to the first aspect disclosed by the utility model, a head assembly is provided. The head assembly includes a head seat, a head cover, and a driving component. Among them, the head seat and the head cover are assembled through a fixing structure and form an accommodation cavity. The fixing structure is located inside the head assembly. The driving component is located in the accommodation cavity, and the driving component is connected with a blade, and the blade is located outside the accommodation cavity.

[0007] With the above settings, the fixing structure of the utility model is located inside the head assembly to be able to fix the head seat and the head cover from the inside of the accommodation cavity. Thus, compared with the way of directly locking the head cover outside the head seat, the head assembly of the utility model can prevent water vapor or liquid from entering the inside of the head assembly along the fixing structure arranged outside, damaging the driving component (in some cases, damaging electronic components such as the control board), having a good sealing effect, few use failures of the head assembly and the cooking machine, and also preventing water vapor or liquid from entering the accommodation cavity and causing odor, etc., and having a good user experience.

[0008] In one embodiment, the head assembly further includes a first sealing member, the first sealing member is arranged between the head seat and the head cover, and along the radial direction of the head seat, the first sealing member is closer to the center of the head assembly than the fixing structure.

[0009] With the above settings, in the radial direction of the machine head base, when the first seal is closer to the center of the machine head assembly relative to the fixed structure, the fixed structure is located in the accommodation cavity, and the fixed structure is isolated from the accommodation cavity by the first seal. Thus, for example, after the machine head assembly and the cup body are installed, the first seal can effectively prevent the water vapor in the cup body from entering the accommodation cavity and damaging the components inside the machine head assembly (for example, the drive assembly, the control board or related electronic components), thereby better avoiding malfunctions of the machine head assembly. In addition, based on the above position relationship, the first seal contacts the water vapor or liquid first, isolates the accommodation cavity from the outside of the machine head assembly, and can also protect the fixed structure in the accommodation cavity from being eroded by the liquid. At the same time, the first seal can also absorb the vibration and noise at the connection between the machine head base and the machine head cover, improving the smooth operation of the machine head assembly.

[0010] In one embodiment, the machine head base includes an installation cavity. The top of the machine head cover is located in the installation cavity and is assembled in the installation cavity through the fixed structure.

[0011] With the above settings, the installation cavity is part of the accommodation cavity. The installation cavity can reserve an operating space for installing the fixed structure or assembling the machine head base and the machine head cover, facilitating the assembly of the machine head cover and the machine head base. Thus, by fixing the machine head cover and the machine head base in the installation cavity through the fixed structure, the fixed structure can be placed in the installation cavity, and the fixed structure can be arranged inside the machine head assembly to avoid direct contact between water vapor or liquid and the fixed structure, thereby protecting the fixed structure from being eroded.

[0012] In one embodiment, the first seal is pressed between the machine head cover and the inner wall of the installation cavity under the fixing action of the fixed structure.

[0013] With the above settings, the first seal is pressed between the machine head cover and the inner wall of the installation cavity under the fixing action of the fixed structure. In this way, the first seal is more closely combined with the machine head cover and the inner wall of the installation cavity, the sealing effect of the first seal is better, and it can further avoid water vapor or liquid from entering the inside of the machine head assembly.

[0014] In one embodiment, a bearing platform is provided on the inner wall of the installation cavity, and a flange of the machine head cover is provided on the top of the machine head cover. The first seal is pressed between the bearing platform and the flange of the machine head cover by the fixed structure.

[0015] With the above settings, the contact area between the headstock and the flanging of the nose cowl is increased through the cooperation of the bearing platform and the flanging of the nose cowl, which can not only improve the sealing performance and bearing capacity between the two, but also provide an installation surface for the installation and fixing structure, thereby improving the connection stability between the headstock and the nose cowl. In addition, when the first seal is pressed between the bearing platform and the flanging of the nose cowl under the action of the fixing structure, this pressing makes the bearing platform, the flanging of the nose cowl and the first seal fit tightly, thereby effectively preventing water vapor from entering the accommodation cavity from the outside and better avoiding malfunctions of the nose assembly.

[0016] In one embodiment, the bearing platform is provided with a first positioning groove, the first seal is installed in the first positioning groove, and the part of the first seal extending out of the first positioning groove is pressed by the flanging of the nose cowl.

[0017] With the above settings, the first seal is positioned by the first positioning groove to prevent the first seal from moving, so as to improve the sealing performance of the first seal for the accommodation cavity. In addition, the first positioning groove can also increase the contact area between the bearing platform and the first seal. If water vapor or liquid enters, the entry path of the water vapor or liquid can also be extended to delay the entry of the water vapor or liquid.

[0018] In one embodiment, the flanging of the nose cowl is provided with a second positioning groove, the first seal is installed in the second positioning groove, and the part of the first seal extending out of the second positioning groove is pressed by the bearing platform.

[0019] With the above settings, the first seal is positioned by the second positioning groove to prevent the first seal from moving, so as to improve the sealing performance of the first seal for the accommodation cavity. In addition, the second positioning groove can also increase the contact area between the bearing platform and the first seal. If water vapor or liquid enters, the entry path of the water vapor or liquid can also be extended to delay the entry of the water vapor or liquid.

[0020] In one embodiment, the bearing platform is provided with a first positioning groove, the flanging of the nose cowl is provided with a second positioning groove, and the first seal is located in the second positioning groove and the first positioning groove.

[0021] With the above settings, the first positioning groove and the second positioning groove are set at the same time. Through the cooperation of the first positioning groove and the second positioning groove, the positioning effect on the first seal can be further improved to prevent the first seal from moving, so as to improve the sealing performance of the accommodation cavity. When the nose assembly includes the first positioning groove and the second positioning groove, the first positioning groove and the second positioning groove can also be used to further increase the contact area between the bearing platform and the flanging of the nose cowl and the first seal, thereby further delaying the entry of water vapor or liquid.

[0022] In one embodiment, the headstock includes an upper headstock cover and a lower headstock cover. The lower headstock cover is provided with the installation cavity, and the lower headstock cover and the upper headstock cover are fixedly assembled.

[0023] With the above arrangement, by providing the installation cavity in the lower headstock cover, it is convenient to assemble the head cover and the headstock. For example, the installation space can also serve as an operating space, and the fixing structure can be operated in this space to fix the head cover to the lower headstock cover, and then the upper headstock cover is fixedly assembled to the lower headstock cover, thereby realizing the assembly of the head assembly and making the assembly of the head assembly simpler.

[0024] In one embodiment, the head assembly includes a second seal, and the second seal is disposed between the upper headstock cover and the lower headstock cover to isolate the installation cavity from the outside.

[0025] With the above arrangement, when the upper headstock cover and the lower headstock cover are assembled, the second seal is squeezed and filled into the gap between the upper headstock cover and the lower headstock cover to prevent moisture or liquid from entering the accommodation cavity, further preventing moisture or damage to the drive assembly or other electronic components and improving the user experience.

[0026] In one embodiment, a limiting structure is provided between the head cover and the headstock, and the limiting structure and the fixing structure are alternately distributed along the circumferential direction of the head assembly.

[0027] With the above arrangement, the limiting structure can prevent relative displacement between the headstock and the head cover, thereby improving the connection stability between the headstock and the head cover, and further improving the sealing performance of the accommodation cavity to prevent moisture or liquid from entering the accommodation cavity, thereby reducing the use failures of the head assembly. Moreover, when the limiting structure and the fixing structure are alternately distributed along the circumferential direction of the head assembly, it is equivalent to having limiting structures on both sides of the fixing structure. The limiting structure can limit the relative displacement between the head cover and the headstock, and thus can prevent the fixing structure from loosening. At the same time, fixing structures are provided on both sides of the limiting structure, which can also reduce the impact of the relative sliding between the head cover and the headstock on the limiting structure. Thus, the connection stability between the head cover and the headstock is improved through the alternate distribution of the limiting structure and the fixing structure. In addition, through the alternate distribution of the limiting structure and the fixing structure, the number of fixing structures required to be installed between the head cover and the headstock can also be reduced to improve the assembly efficiency of the head cover and the headstock.

[0028] In one embodiment, the upper headstock cover and the lower headstock cover are fixedly assembled through the limiting structure.

[0029] With the above settings, the limiting structure can not only achieve the assembly between the lower cover of the machine head base and the upper cover of the machine head base, but also limit the position between the machine head cover and the machine head base. One structure realizes two functions, which can reduce the number of parts of the machine head assembly, and the structure of the machine head assembly is simple.

[0030] In one embodiment, the limiting structure includes a limiting hole provided at the top of the machine head cover and a limiting post provided on the inner wall of the accommodating cavity. The limiting post passes through the limiting hole. The machine head assembly includes a fastener, and the fastener is connected to the limiting post to realize the fixed assembly of the upper cover and the lower cover of the machine head base.

[0031] With the above settings, the limiting post passes through the limiting hole, and in combination with the fixing structure, the machine head cover and the machine head base are fixed. The above-mentioned passing through reduces the number of screws and the process of screwing the screws. Correspondingly, the assembly between the machine head cover and the machine head base is simple.

[0032] According to the second aspect disclosed in the present invention, a cooking machine is provided. The cooking machine includes a cup body and the above-mentioned machine head assembly, and the machine head cover extends into the cup body.

[0033] With the above settings, the cooking machine at least has the beneficial effects brought by the machine head assembly. Description of the Drawings

[0040] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present embodiment, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0041] In the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. At the same time, in the description of the present utility model, terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0042] See Figure 1 and Figure 2 , the present utility model provides a head assembly 10, including a head base 1, a head cover 2 and a drive assembly 3. Among them, the head base 1 and the head cover 2 are assembled through a fixing structure 5 and form a receiving cavity 21. The fixing structure 5 is located inside the head assembly 10. That is, the fixing structure 5 cannot be seen from the outer wall of the head assembly 10, so as to completely hide the fixing structure 5 inside the head assembly 10. In this way, it can not only prevent the fixing structure 5 from being eroded by liquid, but also ensure the outer wall of the head assembly 10 is beautiful and flat, reduce dirt residue, and as described later, avoid fewer use failures of the head assembly and the food processor. The drive assembly 3 is partially located in the receiving cavity 21, and the drive assembly 3 is connected with a blade 31, and the blade 31 is located outside the receiving cavity 21. In addition, the receiving cavity 21 can also accommodate a control board, related electronic components, etc. as described later.

[0043] It should be noted that the driving component 3 in the present utility model includes a motor component, and the motor component is used to drive the blade 31 to rotate. However, based on this function, the driving component 3 is not limited thereto, as long as this function can be achieved. For example, the driving component 3 includes a first component and a second component. The first component is connected to the blade 31, and the second component and the first component are magnetically driven, thereby driving the blade 31 to rotate. Four blades 31 are shown in the figure, which are four-blade knives, but the number of blades 31 is not limited thereto. Figure 2 It is shown that a part of the motor component is located in the accommodation cavity 21. The output shaft of the motor component is connected to the cutter shaft to drive the cutter shaft to drive the blade 31 to rotate. The control board (which can be a PCB board) is electrically connected to the driving component 3 and is used to control the operation of the driving component 3. Some physical buttons or virtual buttons can also be provided on the machine head base for sending control signals to the control board, such as stopping, starting, making soy milk, squeezing juice, and so on.

[0044] In some related designs, the screw directly locks the machine head cover 2 outside the machine head base 1. In this way, water or liquid will enter the inside of the machine head assembly 10 from the screw hole that cooperates with the screw, resulting in short circuits, odors, etc. Moreover, the head of the screw will be exposed outside the machine head assembly and is prone to rust. As set above, the fixing structure 5 is located inside the machine head assembly 10 and can fix the machine head base 1 and the machine head cover 2 from the accommodation cavity 1a without the screw holes communicating with the outside of the machine head assembly. Thus, it is possible to prevent water vapor or liquid from entering the inside of the machine head assembly along the screw and damaging the driving component (in some cases, damaging electronic components such as the control board). In addition, since the fixing structure 5 is located inside the machine head assembly 10, it can also protect the fixing structure 5 from direct contact with external liquids, which can also extend the service life of the fixing structure 5. For example, the fixing structure 5 can include screws. Setting the fixing structure 5 inside the machine head assembly is beneficial to avoid the screws being exposed and rusting. To sum up, the fixing structure 5 located inside the machine head assembly improves the sealing effect of the machine head assembly, reduces the usage failures of the machine head assembly and the food processor (such as avoiding short circuits and damage to electronic components), and can also prevent water vapor or liquid from entering the accommodation cavity and causing odors, providing a good user experience.

[0045] Based on the function of the above-mentioned fixing structure 5, the structure of the fixing structure 5 is not limited and is not limited to including screws as described later, and can be a buckle or the like.

[0046] See Figures 2 to 5, in some embodiments, the head assembly 10 further includes a first seal 4. The first seal 4 is disposed between the head base 1 and the head cover 2. Along the radial direction 1c of the head base, the first seal 4 is closer to the center 10a of the head assembly than the fixed structure 5. Generally, the projection of the head base is circular. At this time, the radial direction is the diameter direction of the circle. When the projection of the head base is non-circular, the radial direction is the horizontal direction.

[0047] With the above arrangement, along the radial direction of the head base 1, when the first seal 4 is closer to the center of the head assembly 10 than the fixed structure 5, the fixed structure 5 is located in the accommodation cavity 21, and the fixed structure 5 is isolated from the accommodation cavity 21 by the first seal 4. Thus, for example, after the head assembly is installed on the cup body 20, the first seal 4 can effectively prevent the water vapor in the cup body 20 from entering the accommodation cavity 21 and damaging the components in the head assembly 10 (for example, the drive assembly 3, the control board or related electronic components), thereby better avoiding malfunctions of the head assembly 10. In addition, based on the above distance relationship, the first seal 4 contacts the water vapor or liquid first, and the first seal 4 can protect the fixed structure 5 in the accommodation cavity 21 from being eroded by the liquid. For example, when the fixed structure 5 includes screws, it can prevent the screws from rusting. At the same time, the first seal 4 can also absorb the vibration and noise at the connection between the head base 1 and the head cover 2, improving the running smoothness of the head assembly 10.

[0048] As an example, as Figure 5 shown, the head base 1 is provided with an outer surface 1b. Along the radial direction of the head base 1, when the first seal 4 is closer to the center of the head assembly 10 than the fixed structure 5, it is equivalent to that the distance from the fixed structure 5 to the outer surface 1b is less than the distance from the first seal 4 to the outer surface 1b, that is Figure 5 a shown is less than b.

[0049] Optionally, the first seal 4 can be set as a sealing ring, which seals between the head cover 2 and the head base 1 along the circumferential direction of the head cover 2. Optionally, the material of the first seal 4 can be set as rubber, silica gel, metal, etc., which is not limited in the present invention.

[0050] Referring to Figure 1 and Figure 2 , the head base 1 includes an installation cavity 1a. There is no limit on how to form the installation cavity 1a. The installation cavity 1a at least accommodates the top of the head cover 2. In some embodiments, it can also accommodate a control board, etc., and the structure is not limited. The top of the head cover 2 is located in the installation cavity 1a and is assembled in the installation cavity 1a through the fixed structure 5.

[0051] With the above settings, the installation cavity 1a is part of the accommodation cavity 21. The installation cavity 1a can reserve an operating space for the installation and fixation structure 5 or for assembling the machine head base and the machine head cover, facilitating the assembly of the machine head cover and the machine head base. Thus, by fixing the machine head cover 2 and the machine head base within the installation cavity 1a through the fixation structure 5, the fixation structure 5 can be placed within the installation cavity 1a, so that the fixation structure 5 is arranged inside the machine head assembly, avoiding direct contact between moisture or liquid and the fixation structure 5, thereby protecting the fixation structure 5 from being eroded.

[0052] In some embodiments, the first seal 4 is pressed between the machine head cover 2 and the inner wall of the installation cavity 1a under the fixing action of the fixing structure 5.

[0053] With the above settings, the first seal 4 is pressed between the machine head cover 2 and the inner wall of the installation cavity 1a under the fixing action of the fixing structure 5. In this way, the first seal 4 is more closely combined with the machine head cover 2 and the inner wall of the installation cavity 1a, and the sealing effect of the first seal 4 is better, further avoiding moisture or liquid from entering the interior of the machine head assembly 10, and at the same time preventing moisture and liquid from eroding the fixing structure 5.

[0054] See Figure 4 and Figure 5 , in some embodiments, for the purpose of at least facilitating the fixation of the machine head base 1 and the machine head cover 2 from within the accommodation cavity 21, the inner wall of the installation cavity 1a is provided with a bearing platform 11. The bearing platform 11 can be a circle or can be arranged at intervals in the circumferential direction, as long as the purpose can be achieved. In this embodiment, the bearing platform 11 extends from the inner wall towards the inner wall of the installation cavity 1a. The top of the machine head cover 2 is provided with a machine head cover flange 22. The machine head cover flange 22 can Figure 4 be like that, a circle, and can be arranged at intervals in the circumferential direction (for example, when the bearing platform 11 is a circle, it is arranged at intervals; of course, even if the bearing platform 11 is not a circle, it can also be arranged at intervals). In short, in this embodiment, the first seal 4 is pressed between the bearing platform 11 and the machine head cover flange 22 by the fixing structure 5.

[0055] It should be noted that the fixing structure 5 can be connected between the bearing platform 11 and the machine head cover flange 22 to fix the machine head base 1 and the machine head cover 2, and at the same time use the bearing platform 11 and the machine head cover flange 22 to press the first seal 4. Of course, the fixing structure 5 can also be connected at other positions between the machine head base 1 and the machine head cover 2, as long as it can ensure that while the machine head base 1 and the machine head cover 2 are connected and fixed, the bearing platform 11 and the machine head cover flange 22 are in contact and press the first seal 4. The present invention does not make any restrictions.

[0056] With the above settings, the contact area between the headstock base 1 and the flanging 22 of the nose cowling is increased through the cooperation of the carrier table 11 and the flanging 22 of the nose cowling, which can not only improve the sealing performance and load-bearing capacity between the two, but also provide an installation surface for the installation and fixing structure 5, improving the connection stability between the headstock base 1 and the nose cowling 2. In addition, when the first seal 4 is pressed between the carrier table and the flanging of the nose cowling under the action of the fixing structure 5, this pressing makes the carrier table, the flanging of the nose cowling and the first seal fit tightly, thereby effectively preventing water vapor from entering the accommodation cavity from the outside and better avoiding malfunctions of the nose assembly.

[0057] In other embodiments, the first seal 4 can also be arranged between the inner wall of the installation cavity 1a except the carrier table 11 and the top of the nose cowling 2. The present invention does not make any restrictions as long as it can prevent water vapor or liquid from entering the accommodation cavity 21.

[0058] As an example, refer to Figure 3 , the headstock base 1 has a first end 12a and a second end 12b arranged at intervals along the depth direction of the accommodation cavity 21, and the carrier table 11 is arranged at the first end 12a. The carrier table 11 fits with the flanging 22 of the nose cowling 2 of the nose cowling 2. Thus, the nose cowling 2 and the installation cavity 1a form the accommodation cavity 21. In Figure 6 , the fixing structure 5 includes a screw 51, a first mounting hole 111 and a second mounting hole 221. The wall surface of the carrier table 11 facing the second end 12b is provided with the first mounting hole 111, and the flanging 22 of the nose cowling 2 is provided with a second mounting hole 221 corresponding to the first mounting hole 111. The screw sequentially passes through the second mounting hole 221 and the first mounting hole 111 to press the flanging 22 of the nose cowling against the carrier table 11. Thus, the top of the nose cowling 2 is fixed to the inner wall by the fixing structure 5. The first mounting hole 111 is set as a blind hole, so that the installed screw 51 is arranged in the accommodation cavity 21.

[0059] In addition, in other embodiments, the fixing structure 5 can also be a fastening thread. As an example, an internal thread is provided on the inner wall of the headstock base 1, and an external thread is provided on the top of the nose cowling 2. When the headstock base 1 and the nose cowling 2 rotate relative to each other, the cooperation of the internal thread and the external thread can make the headstock base 1 and the nose cowling 2 buckle or separate. Or, in other embodiments, the fixing structure 5 can also be a snap component. The snap component includes a first snap and a second snap. The first snap is arranged on the inner wall of the installation cavity 1a of the headstock base 1, and the second snap is arranged on the top of the nose cowling 2. When the headstock base 1 and the nose cowling 2 rotate relative to each other in different directions, the first snap can be buckled or separated from the second snap to make the headstock base 1 and the nose cowling 2 buckle or separate.

[0060] See Figure 5 Figure 5 , in some embodiments, the carrier table 11 is provided with a first positioning groove 112, the first seal 4 is installed in the first positioning groove 112, and the portion of the first seal 4 extending out of the first positioning groove 112 is pressed by the flange 22 of the machine head cover.

[0061] With the above arrangement, the first positioning groove 112 is used to position the first seal 4 to prevent the first seal 4 from moving, so as to improve the sealing performance of the first seal 4 for the accommodation cavity 21. In addition, the first positioning groove 112 can also increase the contact area between the carrier table 11 and the first seal 4. If water vapor or liquid enters, the entry path of the water vapor or liquid can also be extended to delay the entry of the water vapor or liquid.

[0062] In some embodiments, the flange 22 of the machine head cover is provided with a second positioning groove 222, the first seal 4 is installed in the second positioning groove 222, and the portion of the first seal 4 extending out of the second positioning groove 222 is pressed by the carrier table 11.

[0063] With the above arrangement, the second positioning groove 222 is used to position the first seal 4 to prevent the first seal 4 from moving, so as to improve the sealing performance of the first seal 4 for the accommodation cavity 21. In addition, the second positioning groove 222 can also increase the contact area between the carrier table 11 and the first seal 4. If water vapor or liquid enters, the entry path of the water vapor or liquid can also be extended to delay the entry of the water vapor or liquid.

[0064] In some embodiments, the first carrier table 11 is provided with a first positioning groove 112, the flange 22 of the machine head cover is provided with a second positioning groove 222, and the first seal 4 is located in the second positioning groove 222 and the first positioning groove 112.

[0065] With the above arrangement, the first positioning groove 112 and the second positioning groove 222 are provided at the same time. Through the cooperation of the first positioning groove 112 and the second positioning groove 222, the positioning effect of the first seal 4 can be further improved to prevent the first seal 4 from moving, so as to improve the sealing performance of the accommodation cavity 21. And, when the machine head assembly includes the first positioning groove and the second positioning groove, the first positioning groove 112 and the second positioning groove 222 can also further increase the contact area between the carrier table 11 and the flange 22 of the machine head cover and the first seal 4, thereby further delaying the entry of water vapor or liquid.

[0066] See Figure 6, in some embodiments, the nose cover 2 can also be disposed outside the nose base 1. At this time, the top of the nose cover 2 is fixed to the nose base 1 by the fixing structure 5. Such a setting can also prevent the fixing structure 5 from being eroded by liquid. Meanwhile, a first seal 4 is disposed between the nose base 1 and the nose cover 2 to isolate the fixing structure 5 from the liquid or water vapor outside the accommodating cavity 21, thereby preventing the water vapor or liquid from entering the interior of the nose assembly 10 along the fixing structure 5 and avoiding malfunctions of the nose assembly 10.

[0067] It should be noted that, in Figure 6 the implementation manner, based on the function of the fixing structure 5 described above, the structure of the fixing structure 5 is not limited and is not limited to including, for example, the screw 51 described later, and can also be a buckle or the like.

[0068] See back Figure 3 , in some embodiments, the nose base 1 includes an upper nose base cover 13 and a lower nose base cover 12, and the lower nose base cover 12 is provided with the installation cavity 1a. The lower nose base cover 12 and the upper nose base cover 13 are fixedly assembled. The fixing manner of the upper nose base cover 13 and the lower nose base cover 12 is not limited. For example, the upper nose base cover 13 and the lower nose base cover 12 can be fixed by screws, fixed by threaded connection, fixed by buckles, etc.

[0069] As described above, by providing the installation cavity through the lower nose base cover, it is convenient to assemble the nose cover and the nose base. For example, the installation space can also be used as an operation space, and the fixing structure is operated in this space to fix the nose cover to the lower nose base cover, and then the upper nose base cover is fixedly assembled to the lower nose base cover, thereby realizing the assembly of the nose assembly and making the assembly of the nose assembly simpler.

[0070] In the implementation manner of the present utility model, the upper nose base cover 13 can be provided with a control panel (the aforementioned physical buttons or virtual buttons are provided on the control panel), and the control panel can be set as a human-machine interaction interface by being electrically connected to the control board, and it can be used to set the start of the cooking machine 100, load the program, select the function of the cooking machine 100, etc. The installation cavity 1a provided in the lower nose base cover 12 can be used to accommodate a controller or the like connected to the control panel of the upper nose base cover 13. Thus, by assembling the upper nose base cover 13 and the lower nose base cover 12 to form the nose base 1, the formed installation cavity 1a can be used to accommodate control elements such as the control panel, and it is also convenient to open the installation cavity 1a to replace or repair the internal control elements.

[0071] In addition, when the nose base 1 and the nose cover 2 are fixed, the nose cover 2 can be fixed to the lower nose base cover 12 to use the installation cavity 1a of the lower nose base cover to accommodate the fixing structure 5, thereby protecting the fixing structure 5 and preventing the fixing structure 5 from being eroded by liquid.

[0072] Still seeFigure 3 , in some embodiments, the head assembly 10 includes a second seal 7 disposed between the upper head base cover 13 and the lower head base cover 12 to isolate the installation cavity 1a from the outside.

[0073] With the above arrangement, when the upper head base cover 13 and the lower head base cover 12 are assembled, the second seal 7 is squeezed and filled into the gap between the upper head base cover 13 and the lower head base cover 12 to prevent water vapor from entering the accommodation cavity 21, further improving the prevention of water vapor or damage to the drive assembly or other electronic components and enhancing the user experience.

[0074] There is no limitation on how the second seal 7 is disposed between the upper head base cover 13 and the lower head base cover 12. As an example, the upper head base cover 13 is provided with a first connecting portion extending along the periphery of the upper head base cover 13, and the second end portion 12b is provided with a second connecting portion that fits with the first connecting portion. One of the first connecting portion and the second connecting portion is set as a groove 113, and the other is set as a protrusion 132. The second seal 7 is embedded in the groove 113 and abuts against the protrusion 132.

[0075] In other embodiments, when the lower head base cover 12 and the upper head base cover 13 are of a split structure, the assembly of the head cover 2 and the head base 1 through the fixing structure further includes: the lower head base cover 12, the head cover 2, and the fixing structure 5 are integrally injection-molded.

[0076] See Figure 3 and Figure 4 , in some embodiments, a limiting structure 6 is provided between the head cover 2 and the head base 1. The limiting structure 6 and the fixing structure 5 are alternately distributed along the circumferential direction of the head assembly 10. Among them, the limiting structure 6 can be a limiting pin, a limiting block, a fastening screw, etc., and the present invention does not make any limitation.

[0077] With the above arrangement, the use of the limiting structure 6 can prevent relative displacement between the head base 1 and the head cover 2, thereby improving the connection stability between the two, and further improving the sealing performance of the accommodation cavity 21 to prevent water vapor or liquid from entering the accommodation cavity 21, thereby reducing the use failures of the head assembly 10.

[0078] Combined with the fixing structure 5, when the limiting structure 6 and the fixing structure 5 are alternately distributed along the circumferential direction of the machine head assembly 10, it is equivalent to having the limiting structure 6 arranged on both sides of the fixing structure 5. The limiting structure 6 can limit the relative displacement between the machine head cover 2 and the machine head base 1, thereby avoiding loosening of the connection of the fixing structure 5. At the same time, with the fixing structure 5 arranged on both sides of the limiting structure 6, it can also reduce the impact on the limiting structure 6 caused by the relative sliding between the machine head cover 2 and the machine head base 1. Thus, through the alternating distribution of the limiting structure 6 and the fixing structure 5, the connection stability between the machine head cover 2 and the machine head base 1 is improved. In addition, through the alternating distribution of the limiting structure 6 and the fixing structure 5, the number of fixing structures 5 required for installation between the machine head cover 2 and the machine head base 1 can also be reduced, so as to improve the assembly efficiency of the machine head cover 2 and the machine head base 1.

[0079] In other embodiments, when the limiting structure 6 and the fixing structure 5 are distributed along the circumferential direction of the machine head assembly 10, a limiting structure 6 can also be arranged every two fixing structures 5, or one or two limiting structures 6 can be arranged every three fixing structures 5, and so on. The present invention does not make any restrictions.

[0080] See Figure 3 and Figure 4 , in some embodiments, the lower machine head base cover 12 and the upper machine head base cover 13 are assembled through the limiting structure 6.

[0081] With the above arrangement, the limiting structure 6 located in the installation cavity 1a can not only realize the assembly between the lower machine head base cover 12 and the upper machine head base cover 13, but also limit the position between the machine head cover 2 and the machine head base 1. One structure realizes two functions, which can reduce the number of components of the machine head assembly and make the structure of the machine head assembly simple.

[0082] As follows, an example of the limiting structure 6 is described. The limiting structure 6 includes a limiting hole 223 arranged at the top of the machine head cover 2 and a limiting post 61 arranged on the inner wall of the accommodating cavity 21. The limiting post 61 passes through the limiting hole 223. The machine head assembly includes a fastener 62, and the fastener 62 is connected to the limiting post 61 to realize the fixed assembly of the upper machine head base cover 13 and the lower machine head base cover 12.

[0083] Specifically, the limiting structure 6 includes a limiting post 61 and a limiting hole 223. The limiting hole 223 is arranged on the machine head cover flange 22, and the limiting post 61 is arranged on the bearing platform 11, and the limiting hole 223 corresponds to the limiting post 61.

[0084] When assembling the headstock base 1 and the headstock cover 2, the limit post 61 passes through the limit hole 223 to position the carrier 11 and the flanging 22 of the headstock cover. At this time, the flanging 22 of the headstock cover is fixed to the carrier 11 by the fixing structure 5. Thus, the fixing structure 5 and the limiting structure 6 can cooperate with each other to realize the assembly and fixation of the headstock base 1 and the headstock cover 2.

[0085] When the headstock base lower cover 12 and the headstock base upper cover 13 are assembled through the limiting structure 6, the carrier 11 can be arranged on the headstock base lower cover 12, the limit post 61 is arranged on the wall surface of the carrier 11 facing the headstock base upper cover 13, and a column hole is arranged in the limit post 61. When the headstock cover 2 is installed on the headstock base lower cover 12, the flanging 22 of the headstock cover is fixed to the carrier 11 by the fixing structure 5, and the limit post 61 passes through the flanging 22 of the headstock cover through the limit hole 223. The headstock base upper cover 13 is provided with a third mounting hole 63 communicating with the mounting cavity 1a. At this time, the fastener 62 passes through the third mounting hole 63 and extends into the mounting cavity 1a, and is connected to the column hole of the limit post 61 to realize the fixed assembly of the headstock base upper cover 13 and the headstock base lower cover 12.

[0086] Thus, the limiting between the headstock cover 2 and the headstock base 1 is realized through the limiting structure 6. At the same time, the assembly between the headstock base lower cover 12 and the headstock base upper cover 13 is realized through the limiting structure 6.

[0087] As set above, the limiting structure 6 includes a limit post 61 and a limit hole 223. Thus, the limit post 61 and the limit hole 223 are penetrated, and in combination with the fixing structure 5 to fix the headstock cover 2 and the headstock base 1, the foregoing penetration reduces the number of screws and the process of screwing the screws. Correspondingly, the assembly between the headstock cover and the headstock base is simple. For example, when the headstock base lower cover 12 and the headstock base upper cover 13 are fixed by the fastener 62, the number of fasteners 62 can be reduced. Without considering the assembly of the headstock base lower cover 12 and the headstock base upper cover 13, because the limit post can replace the screw, the number of screws 51 can be reduced. In some embodiments, the limiting structure 6 may include a notch provided in one of the inner wall and the flanging 22 of the headstock cover, and a limit post provided in the other. Among them, the notch may be a limit hole with an incomplete closed aperture edge.

[0088] In some embodiments, a part of the headstock base upper cover 13 is recessed into the mounting cavity 1a to form a recess, and the third mounting hole 63 is arranged at the recess to protect the fastener 62 by using the recess and avoid the loosening of the fastener 62 due to external force.

[0089] The above-mentioned head assembly 10 can be applied to various usage scenarios, such as various food processing machines 100 like soybean milk makers, juice extractors, blenders, etc. In addition, the application scenarios of the head assembly 10 can also be water cups, kettles, etc., which are not limited in this embodiment.

[0090] See you later Figure 2 , the present utility model also provides a food processor 100 that applies the above-mentioned head assembly 10. The food processor 100 will be further introduced below.

[0091] A food processor 100 includes the above-mentioned head assembly 10 and a cup body 20, and the head cover 2 extends into the cup body 20.

[0092] In the general working mode of the food processor 100, the user first places the ingredients in the cup body 20, adds water at the same time, then covers the head assembly 10 on the cup body 20, and then interacts through the human-machine interface provided by the head assembly 10 (such as the interface displayed on the upper cover of the head base) (for example, issuing instructions to make soybean milk or rice paste, etc.), and then the control board starts the food processor 100 to work. For example, during the working process of the food processor 100, the water vapor generated in the cup body 20 will not enter the accommodation cavity 21 of the head assembly 10, and the food processor 100 can operate stably. Thereby, the failure rate of the food processor 100 is reduced, and the user experience is improved.
