Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good waterproof performance. Background Technology

[0002] Existing food processors typically include a base with an internal motor and a detachable grinding cup mounted on the base. The grinding cup contains a grinding device connected to the motor. When using the food processor, the user places the ingredients into the grinding cup, and the grinding device rotates at high speed driven by the motor to process the ingredients. This traditional food processor requires the user to manually add water to the grinding chamber to process ingredients such as soy milk, which is very cumbersome. Therefore, to achieve automated processing and cleaning of ingredients, researchers have installed a water tank outside the machine, connected to the grinding cup via a water inlet pipe. When using the food processor, the user can use a water pump to pump water from the tank into the grinding cup, thus automating the food processing and significantly increasing the automation of the entire process. However, after the food processor finishes processing the ingredients, when the user separates the grinding cup from the machine base, the slurry in the grinding chamber will overflow downwards through the pipe under the action of gravity. To avoid this situation, Chinese utility model patent CN202321030745.3 discloses a water circuit structure for a blender, which is equipped with a ball valve in the pipe. When the user lifts the grinding cup, the ball valve seals the pipe under the action of gravity and water pressure to prevent the slurry from flowing out. For general products, the above method can prevent the slurry from overflowing. However, through extensive testing and relying on feedback from a large number of users, the applicant found that the above technical solution has a small probability of technical problems: the disconnection of the water circuit is affected by multiple factors such as the water pressure in the water circuit, the ball valve structure, and the elastic element that pushes the ball valve. There will be a certain time difference between the separation of the crushing cup and the base and the complete disconnection of the water circuit structure. If the user lifts the crushing cup up quickly, some of the water in the base will still splash out under greater pressure, and some of the liquid will splash to the bottom of the crushing cup, especially splashing to circuit positions such as the electrical coupler, causing the electrical components to become damp and insensitive or even fail, which seriously affects the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a food processing machine with good waterproof performance. While ensuring safety by setting a valve assembly in the water coupler to prevent water from overflowing, this invention further solves the low-probability risk of liquid splashing out of the machine base when the grinding cup is lifted, causing the electrical components inside the grinding cup to become damp and malfunction.

[0004] To achieve the above objectives, this utility model provides a food processing machine with good waterproof performance, including a base with an internal motor, a detachable grinding cup mounted on the base and having a grinding chamber inside, a grinding device connected to the motor in the grinding chamber, a water tank that can communicate with the grinding chamber in the base, a mounting platform on the top of the base, the grinding cup being detachably mounted on the mounting platform, a lower water coupler that partially protrudes from the top surface of the mounting platform and communicates with the water tank in the base, an upper water coupler that communicates with the grinding chamber and is coupled to the lower water coupler at the bottom of the grinding cup, a one-way valve in both the upper and lower water couplers, and a water baffle groove surrounding the upper water coupler.

[0005] This application incorporates a water tank connected to the grinding chamber in the machine base, allowing users to directly supply water to the grinding cup during food processing. This eliminates the need for manual water supply and ensures more precise water injection, improving the accuracy of the food-to-water ratio and thus enhancing the texture of the processed food. The machine base also features a partially protruding lower water coupler connected to the water tank, and an upper water coupler at the bottom of the grinding cup that connects to the grinding chamber and couples with the lower water coupler. When the user places the grinding cup on the machine base, the upper and lower water couplers engage, opening the water path and allowing water from the tank to be pumped into the grinding chamber for cleaning and processing the food. Furthermore, both the upper and lower water couplers are equipped with one-way valves, ensuring that they only connect after the grinding cup is properly positioned. This effectively prevents liquid from overflowing from the grinding chamber through the upper coupler when the grinding cup is separated from the machine base, and also prevents water from overflowing from the water tank through the lower coupler under pressure, thus ensuring the food processor's waterproof performance. In addition, a water-retaining groove is installed around the outside of the upper water coupler. When the cup is separated from the machine base, any liquid that splashes out under high pressure will be collected in the groove and prevented from splashing everywhere. This effectively prevents liquid from splashing onto other parts of the bottom of the grinding cup, especially electrical components such as the electrical coupler, which could become damp, malfunction, or even fail. This further enhances the overall waterproof performance of the machine, ensuring its operational stability. It should be noted that in most cases, after the water coupler is separated from the water coupler, the one-way valve can quickly disconnect the water coupler. Even if there is a small probability of water splashing out, usually only a very small amount of water will splash out, and there will not be a large amount of water overflowing. Therefore, the water flow can be blocked by the water baffle, ensuring that the food processing machine is safer and more reliable.

[0006] In a preferred embodiment of a food processor with good waterproof performance, the pulverizing cup includes a cup body, a cup body support located below the cup body, and a heat insulation sleeve fixed below the cup body support. The heat insulation sleeve is partially concave to form a water-blocking groove, and the water inlet coupler passes through the heat insulation sleeve and extends into the water-blocking groove.

[0007] By recessing the heat insulation sleeve to form a water-blocking groove, the forming of the water-blocking groove is simplified. The heat insulation sleeve can also form a water-blocking groove while achieving heat insulation, serving two purposes in one piece. This eliminates the need for a separate structural component to form the water-blocking groove, which helps to simplify the overall machine structure, improve structural compactness, and reduce production costs.

[0008] In a preferred embodiment of a food processing machine with good waterproof performance, a water inlet coupler is clamped between a heat insulation sleeve and a cup body support. The water inlet coupler includes a water inlet end extending out of the heat insulation sleeve and a ring rib extending outward relative to the water inlet end. The ring rib is clamped between the heat insulation sleeve and the cup body support.

[0009] By designing the water inlet coupler to be clamped between the heat insulation sleeve and the cup body support, the water inlet coupler can be installed and fixed simultaneously with the heat insulation sleeve and the cup body support. This simplifies the installation process, improves assembly efficiency, and eliminates the need for additional connecting components such as screws to install the water inlet coupler, thus reducing the number of parts and further enhancing the compactness of the internal structure. The water inlet coupler includes a water inlet end extending from the heat insulation sleeve and a ring rib extending outward relative to the water inlet end. The ring rib is clamped between the heat insulation sleeve and the cup body support, allowing the water inlet coupler to couple with the water outlet coupler through the water inlet end. Simultaneously, the ring rib provides fixation, and its clamping position between the heat insulation sleeve and the cup body support provides significant axial restraint, ensuring the reliability of the water inlet coupler's position and preventing displacement after prolonged insertion and removal, which could lead to inaccurate alignment or even failure to connect with the water outlet coupler.

[0010] In a preferred embodiment of a water-resistant food processing machine, the water coupling includes a protrusion extending from the top surface of the mounting platform, which can be inserted into a water-retaining groove.

[0011] By including a protrusion on the top surface of the mounting platform in the water coupling, which can be inserted into the water-retaining groove, the upper and lower water couplings can be aligned not only by their own positions but also by the alignment of the protrusion and the water-retaining groove when the pulverizing cup is installed on the base. This allows for faster installation and alignment, improving assembly efficiency and accuracy. Furthermore, the cooperation between the protrusion and the water-retaining groove enhances the overall alignment accuracy between the pulverizing cup and the base, thereby improving the transmission stability of the upper and lower connectors and reducing vibration and noise during transmission.

[0012] In a preferred embodiment of a food processing machine with good waterproof performance, the height of the protrusion is no greater than the depth of the water-retaining groove.

[0013] By setting the height of the protrusion to no greater than the depth of the water-retaining groove, ensuring that the protrusion is fully inserted into the water-retaining groove, both sealing is guaranteed and installation difficulties caused by an excessively long protrusion are avoided, further optimizing the assembly experience. At the same time, it ensures that the entire grinding cup can fully fit the mounting platform, thereby improving the connection stability between the grinding cup and the mounting platform, reducing noise and wear caused by loosening, extending the service life of the equipment, and ensuring the efficiency and safety of the food processing process.

[0014] In a preferred embodiment of a food processing machine with good waterproof performance, the first one-way valve includes a sealing plug, a sealing surface extending inward from top to bottom in the water inlet channel, and a spherical surface that seals against the sealing surface.

[0015] By incorporating a sealing surface that slopes inward from top to bottom within the water inlet channel, and a spherical surface on the sealing plug that seals against this surface, the sealing plug automatically and tightly adheres to the sealing surface under gravity and water pressure. This effectively prevents liquid from leaking out of the pulverizing chamber. Furthermore, the sloped sealing surface and the spherical surface on the sealing plug create a universal sealing structure, ensuring a good seal at any angle and preventing leakage due to angular deviations. This further enhances the equipment's waterproof performance and reliability. Moreover, the sloped sealing surface has no bends at the sealing position, allowing for smoother water flow, reducing flow resistance, improving water intake efficiency, and significantly reducing the probability of fine impurities accumulating on the sealing surface. Even if fine impurities are present, they can be flushed away upon the next opening, effectively reducing impurity accumulation in the first check valve and improving its cleanliness, thus ensuring its sealing effect.

[0016] In a preferred embodiment of a food processing machine with good waterproof performance, the lower water coupler includes an outlet end that is plugged into and cooperates with the upper water coupler and has an outlet channel inside. The one-way valve also includes a second one-way valve installed in the outlet channel. The second one-way valve can be moved by the water inlet end by pressing down and opening the outlet channel.

[0017] By setting the second one-way valve to be able to be moved by pressing down on the water inlet end and opening the water outlet channel, the water outlet channel can only be opened when the water inlet end is pressed down to the correct position, that is, when the grinding cup and the base are installed in place. This ensures that the grinding cup and the base are tightly connected, prevents the risk of water leakage caused by improper installation, and improves the waterproof performance and operational safety of the overall structure.

[0018] In a preferred embodiment of a food processor with good waterproof performance, the top of the grinding cup is provided with a water inlet head that communicates with the grinding chamber. The water inlet head is connected to the water inlet coupler through a water inlet pipe. The grinding cup is also provided with a handle, and the water inlet pipe is located inside the handle.

[0019] By incorporating a water inlet head at the top of the grinding cup, which connects to the grinding chamber, and connecting the inlet head to the upper water coupler via an inlet pipe, water can flow inward from the top of the grinding chamber. This effectively prevents the liquid inside the grinding chamber from exerting excessive downward pressure on the upper water coupler, which could lead to a weakened seal or even failure of the lower water coupler, thus further enhancing the waterproof performance. The grinding cup also features a handle, allowing users to easily lift and operate it, improving the user experience. Furthermore, the water inlet pipe is housed within the handle, maximizing space utilization while ensuring top water intake, preventing the inlet pipe from being exposed and affecting aesthetics and ease of use.

[0020] In a preferred embodiment of a food processor with good waterproof performance, the grinding cup includes a cup body forming a grinding chamber and a cup body outer shell sleeved on the outside of the cup body, with the water inlet head clamped between the cup body outer shell and the cup body.

[0021] By setting the water inlet head to be clamped between the outer shell and the cup body, the stability of the water inlet head position is ensured, effectively preventing the water inlet head from shifting during use, which would reduce the seal between the water inlet head and the cup body and cause liquid inside the cup to overflow through the gap between the water inlet head and the cup body, thus further improving the waterproof effect.

Detailed Implementation

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figures 1 to 8 As shown, this utility model provides a food processing machine with good waterproof effect, including a base 2 with a motor inside, a detachable grinding cup 1 mounted on the base 2 and having a grinding chamber inside, a grinding device connected to the motor in the grinding chamber, a water tank 3 that can communicate with the grinding chamber, a mounting platform 21 on the top of the base 2, the grinding cup 1 being detachably mounted on the mounting platform 21, a water coupling 5 that partially protrudes from the top surface of the mounting platform 21 and communicates with the water tank 3, an upper water coupling 4 that communicates with the grinding chamber and is coupled to the lower water coupling 5 at the bottom of the grinding cup 1, a one-way valve in both the upper water coupling 4 and the lower water coupling 5, and a water baffle 6 surrounding the upper water coupling 4.

[0036] This application incorporates a water tank 3 connected to the grinding chamber in the base 2, allowing users to directly supply water to the grinding cup 1 via the water tank 3 during food processing. This eliminates the need for manual water supply and ensures more precise water injection into the grinding cup 1, improving the accuracy of the food-to-water ratio and thus enhancing the taste of the processed food. The base 2 also features a lower water coupler 5 that partially protrudes from the top surface of the mounting platform 21 and connects to the water tank 3. The bottom of the grinding cup 1 has an upper water coupler 4 that connects to the grinding chamber and couples with the lower water coupler 5. When the user places the grinding cup 1 on the base 2, the upper water coupler 4 and the lower water coupler 5 are plugged in and coupled, thus establishing water flow. This allows water from the water tank 3 to be pumped into the grinding chamber by a water pump, completing the food cleaning and processing process. Furthermore, both the upper water coupler 4 and the lower water coupler 5 are equipped with one-way valves, ensuring that they are only connected after the grinding cup 1 is in place. This effectively prevents liquid from overflowing from the grinding chamber through the upper water coupler 4 when the grinding cup 1 is separated from the base 2, and also prevents water from overflowing from the water tank 3 under pressure through the lower water coupler 5, thus ensuring the waterproof performance of the food processor. In addition, a water-retaining groove 6 is provided around the upper water coupler 4. When the cup 11 is separated from the base 2, any liquid that splashes out under high pressure will also be collected in the water-retaining groove 6, preventing it from splashing everywhere. This effectively prevents liquid from splashing to other parts of the bottom of the grinding cup 1, especially electrical circuits such as the electrical coupler, which could cause moisture damage, malfunction, or even failure of electrical components. This further improves the overall waterproof performance of the machine, thereby ensuring its operational stability. It should be noted that in most cases of use, after the lower water coupler 5 is separated from the upper water coupler 4, the one-way valve can quickly disconnect the lower water coupler 5. Even if there is a small probability of water splashing out, usually only a very small amount of water will splash out, and there will not be a large amount of water overflowing. Therefore, the water flow can be blocked by the water baffle 6, ensuring that the food processing machine is safer and more reliable.

[0037] It should be noted that this application does not specifically limit the molding of the water-retaining groove 6. As a preferred embodiment of this application, such as Figure 3 , Figure 4 As shown, the pulverizing cup 1 includes a cup body 11, a cup body support 12 located below the cup body 11, and a heat insulation sleeve 13 fixed below the cup body support 12. The heat insulation sleeve 13 is partially concave to form a water-blocking groove 6. The water inlet coupler 4 passes through the heat insulation sleeve 13 and extends into the water-blocking groove 6.

[0038] By partially recessing the heat insulation sleeve 13 to form the water-blocking groove 6, the forming of the water-blocking groove 6 is simplified. Furthermore, the heat insulation sleeve 13 can form the water-blocking groove 6 while achieving heat insulation, serving two purposes in one piece. This eliminates the need for additional structural components to form the water-blocking groove 6, which helps to simplify the overall machine structure, improve structural compactness, and reduce production costs.

[0039] Furthermore, such as Figure 4 As shown, the water inlet coupler 4 is clamped between the heat insulation sleeve 13 and the cup body support 12. The water inlet coupler 4 includes a water inlet end 41 extending out of the heat insulation sleeve 13 and a ring rib 43 extending outward relative to the water inlet end 41. The ring rib 43 is clamped between the heat insulation sleeve 13 and the cup body support 12.

[0040] By setting the water inlet coupler 4 to be clamped between the heat insulation sleeve 13 and the cup body bracket 12, the water inlet coupler 4 can be installed and fixed at the same time as the heat insulation sleeve 13 and the cup body bracket 12 are installed and connected. This simplifies the installation steps, helps to improve assembly efficiency, and eliminates the need for additional connecting parts such as screws to install the water inlet coupler 4. This helps to simplify the number of parts and further improves the compactness of the internal structure. Furthermore, the water inlet coupler 4 includes a water inlet end 41 extending out of the heat insulation sleeve 13 and a ring rib 43 extending outward relative to the water inlet end 41. The ring rib 43 is clamped between the heat insulation sleeve 13 and the cup body support 12, so that the water inlet coupler 4 can be coupled with the water outlet coupler 5 through the water inlet end 41. At the same time, it can be fixed by the ring rib 43. The ring rib 43 is clamped between the heat insulation sleeve 13 and the cup body support 12, which can provide a large axial limiting effect, ensure the reliability of the position of the water inlet coupler 4, and avoid the situation where the water inlet coupler 4 is displaced after a long period of insertion and removal, resulting in inaccurate alignment with the water outlet coupler 5 or even failure to be inserted.

[0041] As a preferred embodiment of this application, such as Figure 2 As shown, the water coupling 5 includes a protrusion that protrudes from the top surface of the mounting platform 21, and the protrusion can be inserted into the water-blocking groove 6.

[0042] By including a protrusion on the top surface of the mounting platform 21 in the water coupling 5, and having the protrusion inserted into the water baffle 6, on the one hand, when the pulverizing cup 1 is installed on the base 2, the upper water coupling 4 and the lower water coupling 5 can not only be aligned by their own positions, but also by the alignment of the protrusion and the water baffle 6, which helps to improve assembly efficiency and accuracy. On the other hand, the cooperation between the protrusion and the water baffle 6 can improve the overall alignment accuracy between the pulverizing cup 1 and the base 2, thereby improving the transmission stability of the upper and lower connectors and reducing vibration and noise during transmission.

[0043] Furthermore, such as Figure 2 As shown, the height of the protrusion is no greater than the depth of the water-blocking groove 6.

[0044] By setting the height of the protrusion to no greater than the depth of the water-retaining groove 6, ensuring that the protrusion is fully inserted into the water-retaining groove 6, both sealing is guaranteed and installation difficulties caused by an excessively long protrusion are avoided, further optimizing the assembly experience. At the same time, it ensures that the entire grinding cup 1 can be fully fitted with the mounting platform 21, thereby improving the connection stability between the grinding cup 1 and the mounting platform 21, reducing noise and wear caused by loosening, extending the service life of the equipment, and ensuring the efficiency and safety of the food processing process.

[0045] As a preferred embodiment of this application, such as Figure 4 As shown, the upper water coupler 4 includes an inlet end 41 that is plugged into and cooperates with the lower water coupler 5 and has an inlet channel 411 inside. The one-way valve includes a first one-way valve 42 disposed in the inlet channel 411, which can control the opening and closing of the inlet channel 411.

[0046] Furthermore, such as Figure 4 As shown, the first one-way valve 42 includes a sealing plug, and the water inlet channel 411 is provided with a sealing surface 4111 extending inward from top to bottom. The sealing plug is provided with a spherical surface that seals against the sealing surface 4111.

[0047] By providing a sealing surface 4111 extending inwards at an angle from top to bottom within the water inlet channel 411, and a spherical surface on the sealing plug that seals against the sealing surface 4111, the sealing plug automatically and tightly fits against the sealing surface 4111 under gravity and water pressure, effectively preventing liquid from flowing out of the pulverizing chamber. Simultaneously, the angled sealing surface 4111 and the spherical surface on the sealing plug achieve a universal sealing structure, ensuring a good sealing effect at any angle and avoiding leakage problems caused by angle deviation, further improving the waterproof performance and reliability of the equipment. Furthermore, the angled sealing surface 4111 has no bends at the sealing position, allowing for smoother water flow, reducing water flow resistance, improving water inlet efficiency, and significantly reducing the probability of fine impurities depositing on the sealing surface 4111. Even if fine impurities happen to be trapped there, they can be flushed away directly upon the next opening, effectively reducing the accumulation of impurities in the first one-way valve 42, contributing to the cleanliness of the first one-way valve 42, and thus ensuring its sealing effect.

[0048] As a preferred embodiment, such as Figure 6 As shown, the lower water coupler 5 includes an outlet end 51 that is plugged into the upper water coupler 4 and has an outlet channel 53 inside. The one-way valve also includes a second one-way valve 52 installed in the outlet channel 53. The second one-way valve 52 can be moved by the water inlet end 41 and open the outlet channel 53.

[0049] By setting the second one-way valve 52 to be able to be moved by pressing down the water inlet end 41 and opening the water outlet channel 53, the water outlet channel 53 can only be opened when the water inlet end 41 is pressed down to the position, that is, when the grinding cup 1 and the base 2 are installed in place. This ensures that the grinding cup 1 and the base 2 are tightly connected, prevents the risk of water leakage caused by improper installation, and improves the waterproof performance and operational safety of the overall structure.

[0050] Specifically, when the user installs the grinding cup 1 onto the mounting platform 21, the inlet end 41 of the upper water coupler 4 is inserted downward into the outlet end 51 of the lower water coupler 5. The second one-way valve 52 in the outlet channel 53 moves downward under the pressure of the inlet end 41, thus opening the outlet channel 53. When the water pump runs and pumps water out of the water tank 3, the water flows from the outlet channel 53 into the inlet channel 411. The sealing plug moves upward under the water pressure, thus opening the inlet channel 411, thereby supplying water to the grinding chamber. When the food processing is completed and the water pump stops working, the sealing plug moves downward under the spring force and seals the inlet channel 411. When the user lifts the grinding cup 1, the second one-way valve 52 loses the downward pressure and moves upward under the spring force to seal the outlet channel 53.

[0051] As a preferred embodiment of this application, such as Figure 7 , Figure 8 As shown, the top of the pulverizing cup 1 is provided with a water inlet head 7 that communicates with the pulverizing chamber. The water inlet head 7 is connected to the water inlet coupler 4 through a water inlet pipe. The pulverizing cup 1 is also provided with a handle 14, and the water inlet pipe is located inside the handle 14.

[0052] By providing a water inlet head 7 at the top of the grinding cup 1, which communicates with the grinding chamber, and connecting the water inlet head 7 to the upper water coupler 4 via a water inlet pipe, water can flow inward from the top of the grinding chamber through the water inlet head 7. This effectively prevents the liquid in the grinding chamber from exerting excessive downward pressure on the upper water coupler 4, which could lead to a deterioration or even failure of the sealing effect of the lower water coupler 5, thus further improving the waterproof effect. The grinding cup 1 also features a handle 14, allowing users to easily lift and operate the cup, enhancing the user experience. Furthermore, the water inlet pipe is housed within the handle 14, maximizing space utilization while ensuring top water intake, preventing the water inlet pipe from being exposed and affecting aesthetics and ease of use.

[0053] Furthermore, such as Figure 8 As shown, the pulverizing cup 1 includes a cup body 11 forming a pulverizing chamber and a cup body outer shell 15 sleeved on the outside of the cup body 11, with the water inlet head 7 clamped between the cup body outer shell 15 and the cup body 11.

[0054] By setting the water inlet head 7 to be clamped between the outer shell 15 of the cup body and the cup body 11, the stability of the position of the water inlet head 7 is ensured, effectively preventing the water inlet head 7 from shifting during use, which would reduce the seal between the water inlet head 7 and the cup body 11 and cause the liquid inside the cup body 11 to overflow through the gap between the water inlet head 7 and the cup body 11, thus further improving the waterproof effect.

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.
