Technical Field
[0001] This utility model relates to the field of food processor structure technology, specifically to an air vent sealing structure suitable for a split-type food processor and the food processor thereof. Background Technology
[0002] Food processors (such as blenders and soy milk makers) are kitchen appliances that integrate blending, heating, and grinding functions, and are widely used in modern homes due to their high efficiency and convenience. Their structure typically includes a main unit and a container. The main unit houses a drive motor and control module. During operation, the motor's high-speed rotation generates a significant amount of heat, therefore a heat dissipation structure, such as an air inlet / outlet or a cooling fan, is necessary on the base of the main unit to ensure timely heat dissipation and prevent overheating damage.
[0003] However, after use, food residue or liquid often remains on the base and blades of these food processors, requiring thorough cleaning. Due to the heat dissipation structure, the base is usually designed with vents connecting the inside and outside for air circulation, but this creates a risk of water ingress during rinsing, especially since it cannot be directly rinsed with water or placed in a dishwasher. Users typically can only wipe or spot clean, which is insufficient to completely remove residual stains. Long-term accumulation may lead to bacterial growth or affect the device's performance.
[0004] In existing technologies, some food processors attempt to improve heat dissipation efficiency by optimizing the airflow or adding dust filters, but this does not fundamentally solve the waterproof sealing problem. For example, some models use an open bottom heat dissipation design, which improves heat dissipation but further increases the risk of water ingress; other solutions attempt to add simple baffles to the vents, but cannot simultaneously ensure complete sealing during cleaning and airflow during heat dissipation.
[0005] Therefore, there is an urgent need for a new type of waterproof heat dissipation structure that can ensure normal heat dissipation while allowing the base to be washed, thereby improving the user experience and extending the service life of the equipment. Summary of the Invention
[0006] In response to the problems in related technologies, this utility model proposes an air vent sealing structure suitable for a split-type food processor and the food processor itself. When the device is working, it can allow airflow through the base, and when the device is being cleaned, it can seal the base to prevent water from entering, thereby enabling deep cleaning of the base.
[0007] This utility model is implemented as follows:
[0008] A vent sealing structure for a split-type food processor, the split-type food processor including a detachable base and a mixing cup assembly;
[0009] The base has raised support feet on its lower surface, allowing air to circulate from the bottom when the base is in normal placement; the upper surface of the base has a through-hole, and the lower surface has a ventilation opening; the base has a top rod inside, and a return spring is fitted on the top rod; a waterproof block is provided at the bottom of the base.
[0010] The upper end of the top rod is covered with a waterproof sleeve, which is sealed to the opening. The top rod extends upward and protrudes from the opening. The lower end of the top rod extends downward and passes through the base to be fixedly connected to the waterproof block. The waterproof block covers the vent.
[0011] Under normal conditions, the waterproof block blocks and seals the vent. After the base and the stirring cup assembly are assembled, the stirring cup assembly presses down on the top rod, causing the top rod to push the waterproof block downward from the vent. The return spring is compressed, allowing outside air to enter and exit the inner cavity of the base through the vent.
[0012] Through the coordinated operation of the push rod, return spring, waterproof block, and waterproof sleeve, the vent is opened only after the mixing cup assembly is assembled; when the mixing cup assembly is disassembled, the push rod returns to its original position under the action of the return spring, and drives the waterproof block to seal the vent. Ultimately, this allows users to conveniently perform deep cleaning of the base while ensuring its waterproof protection.
[0013] As a further optimization of the above solution, a guide sleeve is fixedly provided inside the base; the guide sleeve includes a vertically oriented guide channel; and at least one vertically oriented directional groove is provided on the side of the guide channel.
[0014] The top rod has a raised directional part on its side; the top rod is connected to the guide channel; the directional part is connected to the directional groove.
[0015] The guide channel is used to assist in guiding the top rod and maintain its vertical extension and contraction. However, the guide rod may be cylindrical and may rotate during extension and contraction; or the guide rod may not be a purely vertical structure, and when the through-hole and vent are misaligned in the vertical direction, the guide rod needs to form a bent structure. All of these situations can lead to unstable force transmission on the guide rod, or even breakage. Therefore, the combination of the directional part and the directional groove can prevent rotational deviation and enhance structural stability.
[0016] As a further optimization of the above solution, the base is provided with a drive motor and a motor bracket for supporting and fixing the drive motor; the guide sleeve is fixedly connected to the motor bracket.
[0017] As a further optimization of the above solution, the upper surface of the base is provided with a raised annular mounting seat; the through hole is opened on the upper surface of the annular mounting seat;
[0018] The bottom of the stirring cup assembly forms an annular groove that is adapted to the annular mounting base;
[0019] The outer side of the annular mounting base is provided with multiple first buckles; the inner side of the annular groove is provided with multiple second buckles; when the base and the stirring cup assembly are rotated into position, the second buckles are located on the outer periphery of the annular mounting base, and the first buckles and the second buckles are engaged with each other one by one.
[0020] As a further optimization of the above solution, the upper end of the top rod forms a first inclined surface; the top of the annular groove is provided with a downwardly protruding pressure block, and the end of the pressure block forms a second inclined surface;
[0021] When the base and the stirring cup assembly are rotated together, the first inclined surface faces the second inclined surface, and the pressing block gradually presses the top rod downward.
[0022] By setting two inclined surfaces, after the base and mixing cup assembly are screwed into place, the pressure block can press down the top rod, which is labor-saving, smooth and efficient.
[0023] As a further optimization of the above solution, the waterproof block and the top rod are an integral structure;
[0024] Alternatively, the waterproof block and the top rod may be detachably connected.
[0025] Specifically, the lower end of the top rod has screw holes. Screws are used to pass through the waterproof block and engage with the screw holes of the top rod to achieve a fixed connection.
[0026] As a further optimization of the above solution, the waterproof block and the top rod are detachably connected; the top rod includes a separate upper rod and a lower rod;
[0027] The upper end of the lower rod is provided with a recessed connecting groove, and the outer periphery of the connecting groove is provided with a protruding limiting baffle; the lower end of the upper rod abuts or presses against the connecting groove; the return spring is sleeved below the limiting baffle, and the radial dimension of the return spring is smaller than the radial dimension of the limiting baffle and larger than the radial dimension of the vent.
[0028] As a further optimization of the above solution, the waterproof block is made of waterproof material;
[0029] Alternatively, the waterproof block may be made of a rigid material; the outer surface of the rigid material may be covered with a waterproof material; or the upper surface and outer edge of the rigid material may be provided with the waterproof material.
[0030] Rigid materials include plastics that are not easily deformed, as well as metals and alloys. Waterproof materials are flexible / elastic materials such as silicone and rubber, and the same applies to waterproof sleeves. When the entire waterproof block is made of waterproof material, an appropriate hardness needs to be selected, depending on the specific application.
[0031] As a further optimization of the above solution, the ventilation opening includes an air inlet and an air outlet;
[0032] The lower surface of the base is provided with a limiting groove, which is adapted to the waterproof block;
[0033] One of the limiting grooves has an air inlet at its top; the other limiting groove has a downward-protruding top, forming an air outlet with its opening facing outwards.
[0034] There are two waterproof blocks and two top rods, which are respectively matched with the air inlet and the air outlet.
[0035] This utility model also provides a food processor, including a detachable base and a mixing cup assembly; the upper surface of the base is provided with a chassis; a drive motor is provided inside the base, and the output end of the drive motor is connected to a transmission shaft; the upper end of the transmission shaft passes through the chassis and is connected to the mixing blades; a heating element that contacts the chassis is also provided inside the base.
[0036] The stirring cup assembly includes a cup body with openings at both the top and bottom; after the stirring cup assembly and the base are assembled, the cup body and the base plate are connected to form a stirring cavity.
[0037] The aforementioned air vent sealing structure is also applied.
[0038] The beneficial effects are as follows:
[0039] This utility model provides a vent sealing structure suitable for a split-type food processor and the food processor itself. Through the coordinated operation of the top rod, return spring, waterproof block, and waterproof sleeve, the ventilation vents automatically open when the mixing cup assembly and base are installed to facilitate heat dissipation, and automatically seal and waterproof when disassembled. This not only ensures the heat dissipation needs of the motor, but also completely solves the technical problem of water entering the base during rinsing, significantly improving the convenience of deep cleaning.
