It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.
[0039] An embodiment of the present utility model discloses a wall breaker. The mentioned wall breaker is a multifunctional high-end cooking machine. Specifically, it can use an ultra-high-speed motor to drive a stainless-steel blade to perform ultra-high-speed cutting and pulverization on food ingredients in the cup body 1, breaking the cell walls of the cells in the food ingredients and releasing the nutrients in the cells. Generally speaking, the wall breaker can have three different function modes. One is the pulp discharging mode, that is, the finished pulp in the cup body 1 after the wall breaker breaks the wall is discharged; the second is the water discharging mode, that is, after the wall breaker soaks or washes the food ingredients in the cup body 1, only the water is discharged; the third is the wall-breaking mode, that is, the relevant flowing channels need to be blocked to avoid pulp leakage during wall breaking.
[0040] The following will describe a wall breaker of the present utility model in conjunction with the attached Figures 1-9 drawings.
[0041] In some embodiments, the wall breaker of the present utility model may specifically include a cup body 1, a housing 2, and a valve core 5; the cup body 1 has a cup outlet 11; the housing 2 is fixed outside the cup body 1 and has a through hole 21 communicating with the cup outlet 11 of the cup body 1. The housing 2 has a first outlet 22 and a second outlet 23, and a first drain pipe 3 is connected to the first outlet 22 and a second drain pipe 4 is connected to the second outlet 23; the valve core 5 has a first drain channel 51 and a second drain channel 52. The valve core 5 is movably arranged in the housing 2 and can move in the housing 2 with at least a first position and a second position; when the valve core 5 is in the first position, the first drain channel 51, the through hole 21, and the first outlet 22 are communicated; when the valve core 5 is in the second position, the second drain channel 52, the through hole 21, and the second outlet 23 are communicated.
[0042] In this embodiment, the wall breaker specifically arranges the valve core 5 inside the housing 2. The housing 2 is specifically provided with a first outlet 22 and a second outlet 23, which are respectively connected to the first drain pipe 3 and the second drain pipe 4. Moreover, there is a movable valve core 5 inside the housing 2. The valve core 5 has at least two different positions inside the housing 2, namely the first position and the second position. When the valve core 5 moves to different positions, different flow channels can be formed, thereby realizing the separate discharge of different liquids. For example, when the valve core 5 moves to the first position, the first drain channel 51, the through hole 21, and the first outlet 22 will form an independent flow channel, which can be specifically used for one of the pulp discharge mode or the water discharge mode. Also, for example, when the valve core 5 moves to the second position, the second drain channel 52, the through hole 21, and the second outlet 23 will form another independent flow channel, which can be specifically used for the other of the pulp discharge mode or the water discharge mode to realize the separate discharge of different liquids.
[0043] In summary, the wall breaker specifically arranges the movable valve core 5 inside the housing 2 to form a built-in valve core 5 structure. Therefore, the movable valve core 5 can well avoid the problem of interference with other workpieces. At the same time, it can also avoid the movement of the valve core 5 being interfered by the outside world, and can effectively improve the stability of the operation of the valve core 5.
[0044] It should be noted that when the valve core 5 moves to the first position, the first drain channel 51, the through hole 21, and the first outlet 22 will form an independent flow channel, while the second drain channel 52 will be blocked by the inner wall of the housing 2, forming only one independent flow channel. When the valve core 5 moves to the second position, the second drain channel 52, the through hole 21, and the second outlet 23 will form another independent flow channel, while the first drain channel 51 will be blocked by the inner wall of the housing 2, also forming only one independent flow channel to avoid cross-flow or liquid leakage problems.
[0045] In some embodiments, the valve core 5 also has a third position when moving within the housing 2. When the valve core 5 is in the third position, the first drain channel 51 and the second drain channel 52 are blocked by the inner wall of the housing 2, and the through hole 21, the first outlet 22, and the second outlet 23 are blocked by the valve core 5. In this embodiment, this wall breaker also has three different function modes, namely, the pulp discharging mode, the water draining mode, and the wall breaking mode. Among them, when the valve core 5 moves to different positions within the housing 2, different function modes can be corresponding. For example, when the valve core 5 moves to the first position, the first drain channel 51, the through hole 21, and the first outlet 22 will form an independent and flowing channel, which can be specifically set as the pulp discharging mode. Also, for example, when the valve core 5 moves to the second position, the second drain channel 52, the through hole 21, and the second outlet 23 will form another independent and flowing channel, which can be specifically set as the water draining mode. Also, for example, when the valve core 5 moves to the third position, the first drain channel 51 and the second drain channel 52 are blocked by the inner wall of the housing 2, and the through hole 21, the first outlet 22, and the second outlet 23 are blocked by the valve core 5, which can be specifically the wall breaking mode.
[0046] In one specific embodiment, since the first drain channel 51 and the second drain channel 52 are provided on the valve core 5, the inlet of the first drain channel 51 can be specifically provided on the side wall of the valve core 5 and the outlet can be specifically provided on the bottom wall of the valve core 5, and the inlet of the second drain channel 52 can be specifically provided on the side wall of the valve core 5 and the outlet can be specifically provided on the bottom wall of the valve core 5. The inlets of the first drain channel 51 and the second drain channel 52 can be specifically provided on the same side wall of the valve core 5. It can be known that during the actual use process, when the valve core 5 moves to the first position, the first drain channel 51, the through hole 21, and the first outlet 22 will form an independent and flowing channel, and the inlet of the second drain channel 52 is specifically blocked by the inner side wall of the housing 2, the outlet of the second drain channel 52 is specifically blocked by the inner bottom wall of the housing 2, and the second outlet 23 is blocked by the bottom surface of the valve core 5. When the valve core 5 moves to the second position, the second drain channel 52, the through hole 21, and the second outlet 23 will form another independent and flowing channel, and the inlet of the first drain channel 51 is specifically blocked by the inner side wall of the housing 2, the outlet of the first drain channel 51 is specifically blocked by the inner bottom wall of the housing 2, and the first outlet 22 is blocked by the bottom surface of the valve core 5. When the valve core 5 moves to the third position, the inlet of the first drain channel 51 is specifically blocked by the inner side wall of the housing 2, the outlet of the first drain channel 51 is specifically blocked by the inner bottom wall of the housing 2, the inlet of the second drain channel 52 is specifically blocked by the inner side wall of the housing 2, the outlet of the second drain channel 52 is specifically blocked by the inner bottom wall of the housing 2. At the same time, the through hole 21 will be specifically blocked by the side surface of the valve core 5, the first outlet 22 is blocked by the bottom surface of the valve core 5, and the second outlet 23 is blocked by the bottom surface of the valve core 5.
[0047] In one specific embodiment, the valve core 5 moves linearly within the housing 2 to switch to the first position, the second position or the third position. With this arrangement, the valve core 5 only needs to move linearly within the housing 2 to switch between different positions, which can effectively improve the efficiency of position switching. Specifically, the third position is specifically set between the first position and the second position. Since the slurry discharging mode will be entered after the wall breaking mode, specifically setting the third position beside the first position can effectively improve the overall working efficiency.
[0048] In one specific embodiment, the wall breaker further includes a drive motor 6 fixed to the housing 2. A gear 61 is fixed to the drive end of the drive motor 6, and a rack 62 is fixed to the valve core 5. The rack 62 meshes with the gear 61. With this arrangement, the linear movement of the valve core 5 within the housing 2 can be specifically achieved through the cooperation of the drive motor 6, the gear 61 and the rack 62, thereby realizing the switching of different positions. Moreover, the cooperation structure of the drive motor 6, the gear 61 and the rack 62 is compact, which can well reduce the overall occupied space.
[0049] In one specific embodiment, the housing 2 extends outward to form an open assembly shell 24 and is communicated with the assembly shell 24 at the intersection. The drive motor 6 is fixed to the assembly shell 24 of the housing 2 and the gear 61 is arranged within the assembly shell 24. The gear 61 passes through the intersection between the housing 2 and the assembly shell 24 and then meshes with the rack 62. With this arrangement, the overall structure can be further made more compact, and the overall occupied space can be further reduced.
[0050] In some embodiments, the wall breaker further includes a control module and a first microswitch 71, a second microswitch 72 and a third microswitch 73 that communicate with the control module. A trigger rib 53 is provided on the valve core 5. The trigger rib 53 is used to abut against the first microswitch 71, the second microswitch 72 or the third microswitch 73 to transmit corresponding position signals to the control module. The first microswitch 71 corresponds to the first position signal, the second microswitch 72 corresponds to the second position signal, and the third microswitch 73 corresponds to the third position signal. In specific applications, since the wall breaker has three different function modes, namely the slurry discharging mode, the water draining mode and the wall breaking mode, and the valve core 5 moves to different positions within the housing 2, which can correspond to different function modes. Therefore, in order to better correspond the movement of the valve core 5 to different positions within the housing 2 with different function modes, it can be specifically achieved by adopting the cooperation structure of the control module and the microswitch.
[0051] For example, the first microswitch 71 can be specifically arranged at the first position. When the valve core 5 moves to the first position, the trigger rib 53 on the valve core 5 will abut against the first microswitch 71, triggering the first microswitch 71 to transmit a first position signal to the control module. This means that the valve core 5 has reached the first position, and then the movement of the valve core 5 is controlled to stop, which means that the wall breaker enters the pulp discharging mode.
[0052] Also for example, the second microswitch 72 can be specifically arranged at the second position. When the valve core 5 moves to the second position, the trigger rib 53 on the valve core 5 will abut against the second microswitch 72, triggering the second microswitch 72 to transmit a second position signal to the control module. This means that the valve core 5 has reached the second position, and then the movement of the valve core 5 is controlled to stop, which means that the wall breaker enters the drainage mode.
[0053] Also for example, the third microswitch 73 can be specifically arranged at the third position. When the valve core 5 moves to the third position, the trigger rib 53 on the valve core 5 will abut against the third microswitch 73, triggering the third microswitch 73 to transmit a third position signal to the control module. This means that the valve core 5 has reached the third position, and then the movement of the valve core 5 is controlled to stop, which means that the wall breaker enters the wall breaking mode.
[0054] Specifically, the control module can specifically include a circuit board 74. The first microswitch 71, the second microswitch 72 and the third microswitch 73 can be electrically connected to the circuit board 74 respectively to achieve the control function. More specifically, the circuit board 74 can be fixed on the housing 2.
[0055] In one specific embodiment, the control module is fixed outside the housing 2; the first microswitch 71, the second microswitch 72 and the third microswitch 73 penetrate through the housing 2 and extend into the housing 2 respectively. With such an arrangement, the structure will be more compact, further reducing the overall occupied space.
[0056] In one specific embodiment, the third microswitch 73 is arranged between the first microswitch 71 and the second microswitch 72. Since the pulp discharging mode will be entered after the wall breaking mode, specifically arranging the third microswitch 73 beside the first microswitch 71 can effectively improve the overall working efficiency.
[0057] In some embodiments, the valve core 5 is detachably arranged in the housing 2. With such an arrangement, the valve core 5 can be specifically detached from the housing 2 to facilitate the cleaning of the valve core 5.
[0058] In one specific embodiment, the housing 2 has an opening for assembling the valve core 5 into the interior of the housing 2, and a cover body 8 is covered at the opening; an elastic member 81 and a pushing member 82 fixed to the elastic member 81 are fixed to the inner side of the cover body 8 facing the valve core 5, and the pushing member 82 acts on the valve core 5 through the compressed elastic member 81. In specific applications, since the valve core 5 can be disassembled from the housing 2, in order to better fix the valve core 5 assembled in the housing 2 on the basis of being detachable, the cooperation of the cover body 8, the elastic member 81 and the pushing member 82 can be specifically adopted. Specifically, the elastic member 81 can be specifically a spring, which has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.
[0059] For example, after assembling the valve core 5 from the opening of the housing 2 into the interior of the housing 2, the cover body 8 can be assembled at the opening of the housing 2. At this time, the pushing member 82 will abut against the valve core 5 and make the elastic member 81 in a compressed state, thereby pressing the valve core 5 tightly inside the housing 2. It should be noted that the relationship between the pushing member 82 and the valve core 5 is an abutting relationship. Therefore, when the valve core 5 moves, it will not drive the pushing member 82 to move synchronously, but will slide to avoid interference problems; and, it has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty. Specifically, the abutting surface between the pushing member 82 and the valve core 5 can be set smoothly to reduce the friction coefficient between the pushing member 82 and the valve core 5.
[0060] In another specific embodiment, the housing 2 has an opening for assembling the valve core 5 into the interior of the housing 2, and a cover body 8 is covered at the opening; an elastic member 81 and a pushing member 82 fixed to the elastic member 81 are fixed to the outer side of the valve core 5 facing the cover body 8, and the pushing member 82 acts on the cover body 8 through the compressed elastic member 81. The difference from the above embodiment is that in the above embodiment, one end of the elastic member 81 is fixed to the pushing member 82 and the other end is fixed to the cover body 8, which is equivalent to forming a whole with the cover body 8. In this embodiment, one end of the elastic member 81 is fixed to the pushing member 82 and the other end is fixed to the valve core 5, which is equivalent to forming a whole with the valve core 5. Specifically, the elastic member 81 can be specifically a spring, which has a simple structure, is convenient for manufacturing and production, and reduces the manufacturing difficulty.
[0061] In some embodiments, the wall breaker can be specifically a soybean milk wall breaker. For a soybean milk wall breaker, among the above-mentioned slurry discharging mode, water discharging mode and wall breaking mode, the slurry discharging mode can be the soybean milk discharging mode, where the preparation of soybean milk has been completed in the soybean milk wall breaker and the finished soybean milk is discharged; the water discharging mode can be the waste water discharging mode, where the cleaning of the ingredients has been completed in the soybean milk wall breaker and the cleaned waste water is discharged; the wall breaking mode can be to break the beans to prepare soybean milk.
[0062] In one specific embodiment, the length of the second liquid discharge channel 52 is longer than that of the first liquid discharge channel 51. In practical applications, for better cleaning of the valve core 5, the shorter first liquid discharge channel 51 is specifically used for discharging slurry, and the longer second liquid discharge channel 52 is specifically used for draining water. Therefore, the area where soymilk adheres in the shorter first liquid discharge channel 51 is not much, which can effectively improve the cleaning efficiency.
[0063] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
