Description
Technical Field
[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a food processing machine with good waterproof performance. Background Art
[0002] The wall-breaking food processors on the market generally include a machine base, a cup body detachably mounted on the machine base, and a cup cover buckled on the cup body. A heating plate with a heating tube is provided at the bottom of the cup body, a control panel is provided inside the machine base, and a coupler is provided between the cup body and the machine base to realize the strong power supply to the heating tube. At the same time, in order to realize intelligent pulping, the food processor must also be equipped with many detection elements for temperature detection, overflow prevention detection, etc., and the temperature signal and overflow prevention detection signal also need to be transmitted through the coupler. However, since the coupler is installed between the cup body and the machine base and needs to transmit weak current and strong current at the same time, it is impossible to wash the entire cup body with water. Otherwise, there will be safety hazards such as water ingress into the coupler and short circuit in the strong current transmission part. In addition, the structural design of the cup body is complex. During the design process, it is necessary to ensure that the coupler is waterproof and the reliability of the coupler pin contact must be ensured. This will also cause a large bonding force between the cup body and the machine base, and it is difficult for users to install.
[0003] The applicant has developed a utility model with application number 201820739437.0, which discloses a food processing machine with a cup body recognition function, which changes the way in which the cup body and the machine base must transmit signals through a strong electric coupler. The food processing machine includes a machine base and a mixing cup. A accommodating seat is provided on the circumference of the cup base of the mixing cup, and an upper accommodating cavity is provided on the inner side of the accommodating seat. A wireless transmitting module that transmits signals after power is turned on is provided in the upper accommodating cavity. A lower accommodating cavity is provided on the top of the machine base, and a wireless receiving module for receiving signals is provided in the lower accommodating cavity. The wireless receiving module is electrically connected to a control board, and the control board recognizes the cup body according to the signal received by the wireless receiving module. The heating mechanism of the food processing machine adopts an electromagnetic heating method or a heat conduction heating method. The electromagnetic coil or the heating body of the heating mechanism is controlled by the control board, and is used intelligently, eliminating the coupler between the cup body and the machine base, greatly reducing the strong electric connection between the cup body and the machine base, and reducing the safety hazards of cleaning the cup body.
[0004] However, it is still inevitable to transmit some weak electrical signals between the cup body and the cup lid of the food processor, such as anti-overflow detection on the cup lid, cup lid in place detection, cup lid temperature detection, etc. Moreover, the applicant found in the further research process that the sealing between the signal transmission modules in the existing food processors is poor. When the product is immersed in water, there is water accumulation in the handle cavity, the upper accommodating cavity or the lower accommodating cavity, and the accumulated water will directly soak the wireless receiving module and the transmitting module. Although the signal transmission modules are weakly connected and will not cause safety problems such as electrical connection due to immersion in water, water entering the accommodating cavity will cause unstable signal transmission between the signal transmission modules and accelerate the aging of each module, and the structure is unreliable.

[0016] On the basis of using the skeleton to fix and limit the detection element, by arranging corresponding perforations and sealing lips on the sealing ring, the perforation position of the detection element can be sealed by the sealing lips on the sealing ring, thereby improving the sealing effect of the detection element and the skeleton, and avoiding abnormal problems such as water leakage.

[0018] By setting an upper conductive part and a lower conductive part, when the cup cover is closed in place, the upper conductive part abuts against the lower conductive part to achieve signal conduction, and the lower conductive part is connected to the wireless signal transmission module, thereby realizing indirect detection of the opening and closing of the cover. At the same time, one of the upper conductive part and the lower conductive part is an elastically movable spring pin, and the other is a spring piece abutting against the spring pin. Compared with the opening and closing cover detection method using a safety switch in the traditional technology, the structure is simplified. Compared with the opening and closing cover detection method using a coupler pin, since the spring pin has a certain amount of elastic activity, the spring pin and the spring piece abut to achieve communication after the cup cover is closed in place, the connection is reliable, and the signal transmission is more reliable and stable.

One end of the anti-overflow motor is connected to the upper conductive part.

[0045] The food processor with good waterproof performance provided in this embodiment adopts the magnetic heating plate 24 to cooperate with the electromagnetic coil 40 for heating. At the same time, the detection element 26 of the mixing cup 20 cooperates with the wireless receiving module 11 in the machine base 10 through the wireless signal transmission module 27 to realize wireless signal transmission, thereby eliminating the need to set a coupler between the mixing cup 20 and the machine base 10, avoiding the strong electrical connection between the mixing cup 20 and the machine base 10, so that the mixing cup 20 can be fully cleaned during the cleaning process, eliminating the safety hazards such as short circuit and electrical connection in the strong electrical transmission part of the mixing cup 20 that appear in traditional technologies, and improving the safety performance of use. In the utility model, the cup base 25 is provided with a sealing cavity 251 for sealing and installing the wireless signal transmission module 27, and the mixing cup 20 also includes a sealing structure arranged between the detection element 26 and the wireless signal transmission module 27. By setting up a sealed cavity 251, the wireless signal transmission module 27 can be installed in a sealed manner, thereby preventing the wireless signal transmission module 27 from being damaged by water when cleaning the cup body 21 or soaking the cup body 21. By setting up a sealing structure between the detection element 26 and the wireless signal transmission module 27, the waterproof effect of the stirring cup 20 is further improved, and the stable transmission of signals between the detection element 26 and the wireless signal transmission module 27 is further guaranteed. Even if water enters the cup body 21, the transmission of the detection signal will not be affected, and the service life of each detection element 26 and the service life of the entire machine are extended.

[0050] In other preferred embodiments, the sealing structure includes a hot-melt tube fixed outside the wiring harness by hot-melt, and the detection element 26 and the wireless signal transmission module 27 are connected by the wiring harness.
[0051] In addition, the present invention does not limit the type of the detection element 26. The detection element 26 can be any one or more of the following implementation examples:
[0052] Implementation example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, the detection element 26 includes a temperature sensor extending into the cup body 21 .
[0053] Specifically, Figure 2 As shown, a seal 50 is arranged between the cup body 21 and the magnetic heating disk 24. The seal 50 includes an annular frame 51 and a sealing ring 52. The sealing ring 52 has an upper edge wrapped around the upper end of the frame 51 and a lower edge wrapped around the lower end of the frame 51. The upper edge and the lower edge are respectively abutted against the cup body 21 and the magnetic heating disk 24. The detection element 26 includes a sensor 261 that penetrates the frame 51 and the sealing ring 52 and extends into the cup body 21.
[0054] By setting a seal 50 between the cup body 21 and the magnetic heating disk 24, the seal 50 includes an annular frame 51 and a sealing ring 52. The frame 51 can strengthen the overall structural strength of the seal 50, so that the seal 50 is not easy to fall off and the structure is stable. The sealing ring 52 includes an upper edging and a lower edging to achieve reliable sealing of the matching gap between the cup body 21 and the magnetic heating disk 24. Therefore, an all-round seal between the cup body 21 and the magnetic heating disk 24 is achieved, the overall sealing of the stirring cup 20 is improved, and liquid leakage is prevented. The detection element 26 includes a sensor 261 that penetrates the frame 51 and the sealing ring 52 and extends into the cup body 21. The frame 51 is used to fix and limit the detection element 26, and the structure is reliable. In this embodiment, the sensor 261 extends into the cup body 21 as a temperature sensor, which can directly detect the temperature of the liquid in the cup body 21 and improve the intelligence of the food processor.
[0055] In fact, the sensor can also be a water level sensor to detect the height of the liquid in the cup body 21 and improve the intelligence of the food processing machine.
[0056] More preferably, in this embodiment, the sealing ring 52 is provided with a through hole for the sensor 261 to penetrate and a sealing lip provided at the through hole. On the basis of using the skeleton 51 to fix and limit the detection element 26, by providing corresponding through holes and sealing lips on the sealing ring 52, the through hole position of the detection element 26 can be sealed by the sealing lip on the sealing ring 52, thereby improving the sealing effect of the detection element 26 and the skeleton 51, and avoiding abnormal problems such as water leakage.
[0057] Implementation Example 2, such as Figure 4-6 As shown, the detection element 26 is used to detect the cover opening and closing signal.
[0058] Specifically, the detection element 26 includes an upper conductive member 262 disposed on the cup cover 22 and a lower conductive member 263 disposed on the cup body 21. One of the upper conductive member 262 and the lower conductive member 263 is an elastically movable spring pin, and the other is a spring sheet abutting against the spring pin. Figure 4 As shown, the upper conductive member 262 is a spring pin, the lower conductive member 263 is a spring sheet, the lower conductive member 263 is connected to the wireless signal transmission module 27, and after the cup cover 22 is closed in place, the upper conductive member 262 and the lower conductive member 263 abut against each other to achieve signal conduction.
[0059] By setting the upper conductive member 262 and the lower conductive member 263, when the cup cover 22 is closed in place, the upper conductive member 262 and the lower conductive member 263 abut against each other to achieve signal conduction, and the lower conductive member 263 is connected to the wireless signal transmission module 27, thereby realizing indirect detection of the opening and closing of the cover. At the same time, one of the upper conductive member 262 and the lower conductive member 263 is an elastically movable spring needle, and the other is a spring piece abutting against the spring needle. Compared with the opening and closing cover detection method using a safety switch in the traditional technology, the structure is simplified. Compared with the opening and closing cover detection method using a coupler pin, since the spring needle has a certain amount of elastic activity, the spring needle and the spring piece abut against each other to achieve communication after the cup cover 22 is closed in place, the connection is reliable, and the signal transmission is more reliable and stable. In addition, the spring needle and the spring piece are easy to install and have strong sealing performance, which can reduce the water ingress into the installation space of the detection element 26 of the stirring cup 20, and the risk of water ingress is small, which is convenient for the whole body water washing of the stirring cup 20, and convenient cleaning.
[0060] Preferably, if Figure 4 , 5 As shown in FIG. 6 , the upper conductive member 262 is a spring pin, and the lower conductive member 263 is a spring sheet. The cup cover 22 is rotatably buckled with the cup body 21 , and the spring sheet is gradually tilted upward along the screwing direction of the cup cover 22 .
[0061] The lower conductive member 263 is a spring sheet, which is arranged on the cup body 21 and is gradually inclined upward along the screwing direction of the cup cover 22. As the cup cover 22 is screwed tighter and tighter, the abutment force between the spring sheet and the spring needle becomes greater and greater, thereby ensuring a reliable connection between the spring sheet and the spring needle after the cup cover 22 is closed in place, thereby achieving stable signal transmission.
[0062] As a preference, Figure 5 As shown, the side of the cup body 21 is provided with a mounting portion, the mounting portion is a handle 28, the upper end of the mounting portion is provided with a notch 281, the lower conductive member 263 is installed at the notch 281, and the sealing structure includes a sealant that seals the matching gap between the lower conductive member 263 and the notch, specifically, as Figure 6 As shown, the lower conductive member 263 is installed on the fixing seat 265, and the lower conductive member 263 and the fixing seat 265 form a lower conductive assembly, and then the lower conductive assembly is installed in the notch, and the fixing seat 265 and the notch 281 are sealed and matched.
[0063] By providing a protruding mounting portion on the side of the cup body 21, a mounting position is provided for the lower conductive member 263, and the lower conductive member 263 is installed at the notch to be exposed, so as to facilitate the abutment between the upper conductive member 262 and the lower conductive member 263 to achieve signal conduction, and by providing sealant in the matching gap between the lower conductive member 263 and the notch, water can be prevented from entering the matching gap, thereby improving the waterproofness of the blending cup 20. Of course, the mounting portion is a handle for the convenience of the user to take the blending cup 20.
[0064] Implementation Example 3, such as Figure 7 As shown, in this embodiment, based on embodiment 2, the detection element 26 also includes an anti-overflow electrode 264 disposed on the cup cover 22 , one end of the anti-overflow electrode 264 is connected to the upper conductive member 262 , and the other end extends into the cup body 21 .
[0065] By setting the overflow prevention electrode 264 to realize overflow prevention detection, the pulping of the food processor is made more intelligent, and the pulping is fully boiled without overflowing, which is convenient to use. One end of the overflow prevention motor 30 is connected to the upper conductive member 262. Therefore, after the cup cover 22 is closed, the upper conductive member 262 and the lower conductive member 263 not only realize the conduction of the detection signal of opening and closing the cover, but also realize the conduction of the overflow prevention signal, so as to realize the integration of functions and simplify the structure of the whole machine.
[0066] In addition, in order to further achieve the waterproof property of the base 10 of the present invention, in a preferred embodiment, the wireless receiving module 11 is encapsulated in the base 10 through a glue potting layer.
