Description

Technical Field

[0001] The utility model relates to the field of food processing electrical appliances, in particular to an anti-deformation cover opening and stopping device. Background Art

[0002] At present, some food processing appliances are provided with a barrel body and a cover body, such as a commercial soybean milk maker. Since a stirring blade is provided in the commercial soybean milk maker, in order to improve the safety of use, the barrel body needs to be sealed with the cover body before the commercial soybean milk maker can start working. Therefore, the prior art sets a power switch assembly on the outside of the barrel body, and the power switch assembly includes a power switch, and the power switch includes a switch button. A driving rod is set at the periphery of the cover body, and the driving rod is extended in the up and down directions. Therefore, when the cover body is covered on the barrel body from top to bottom, the driving rod is also inserted downward into the power switch assembly at the same time, so that the lower end of the driving rod can press the switch button in the power switch assembly, so that the commercial soybean milk maker is connected to the power supply, and then the stirring function or heating function of the commercial soybean milk maker can be turned on. If the cover body is opened, the driving rod is separated from the barrel body. When the switch button is turned on, the commercial soymilk maker will be disconnected from the power supply. Even if the stirring or heating functions are not turned off, the commercial soymilk maker will stop immediately. The above-mentioned commercial soymilk maker can refer to the "soymilk maker" with Chinese appearance patent publication number CN307559363S; in order to place the power switch outside the barrel, the power switch assembly includes a side cover made by injection molding process, the opening of the side cover is horizontally opened and faces the middle of the barrel, the side cover is arranged on the outside of the barrel, and the power switch is fixed on the side cover. During daily use, the side cover will inevitably be hit. After long-term use, the side cover is prone to deformation, which causes the position of the power switch fixed to the side cover to change, resulting in the drive rod triggering the switch button to fail. Therefore, it is necessary to improve the above-mentioned switch structure in the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The anti-deformation cover opening and stopping device of the utility model is as follows: Figure 1 and Figure 2 As shown, it includes a switch assembly 3 and a switch driving rod 22 provided on the cover body 2. Specifically, an outer lug 21 is welded on the outer periphery of the cover body 2, and the switch driving rod 22 is provided on the lower side of the outer lug 21. The switch driving rod 22 is provided in an upright manner. Figure 2 As shown, the switch assembly 3 is provided with a power switch 31, and the power switch 31 is provided with a switch button 311 that can be pressed by the lower end of the switch driving rod 22; specifically, as shown in FIG. Figure 1 As shown, the cover 2 is lowered to cover the barrel mouth of the barrel body 1. At the same time, the switch driving rod 22 moves downward. When the cover 2 and the barrel body 1 are assembled, the lock 5 set on the barrel body 1 is buckled with the cover 2, as shown in FIG. Figure 2 As shown, at this time, the lower end of the switch driving rod 22 presses the switch button 311, so that the power switch 31 is turned on; the cover body 2 is moved upward away from the barrel body 1, and the lower end of the switch driving rod 22 leaves the switch button 311. The switch button 311 moves upward and resets under the push of the elastic restoring force of the elastic part in the power switch 31, so that the power switch 31 is turned off.

[0030] The switch assembly 3 includes an inner support and an outer support for installation on the outside of the barrel body 1. The inner support is arranged in the outer support, and the power switch 31 is arranged on the inner support. Therefore, when the switch assembly 3 is subjected to impact force, the outer support is first impacted, and then the impact force is transmitted to the inner support, and the attenuated impact force is then transmitted to the power switch 31, thereby avoiding the inner support used to support the power switch 31 from being subjected to direct impact from the outside; by setting a combined structure of the inner support and the outer support, it is beneficial to disperse and unload the external impact force, avoid the inner support from being easily deformed and displaced due to direct impact, and reduce the degree of displacement of the power switch 31, thereby helping to improve the durability of the cover opening and shutdown device.

[0031] In some embodiments, as Figure 2 and Figure 3 As shown, the outer support member is configured as a protective cover 35, the inner support member is configured as an inner mounting shell 34, and the power switch 31 is mounted in the upper portion of the inner mounting shell 34. Specifically, in order to adapt to the external structure of the power switch 31, the inner mounting shell 34 can be manufactured using an injection molding process. Since the protective cover 35 mainly serves a protective function, the internal structure of the protective cover 35 is relatively simple. Therefore, the protective cover 35 can be manufactured using a relatively strong material such as stainless steel or carbon steel, and the protective cover 35 can be manufactured using a sheet metal process. A mounting plate can be welded to the outer wall of the barrel body 1. The protective cover 35 can be fixed to the barrel body 1 by using corresponding screws passing through the protective cover 35 and connecting with the threaded holes on the mounting plate. Therefore, the cover opening of the protective cover 35 is opened in the horizontal direction, and the cover opening of the protective cover 35 is located on the side of the protective cover 35 that is close to the outer wall of the barrel body 1, which is equivalent to the protective cover 35 covering the outer wall of the barrel body 1.

[0032] By arranging the inner mounting shell 34 to be installed in the protective cover 35, the inner mounting shell 34 is prevented from being directly impacted, and deformation of the inner mounting shell 34 is avoided as much as possible. In addition, the structure of the protective cover 35 is conducive to increasing the structural strength of the switch assembly 3, and the protective cover 35 is not easy to deform. After long-term use, the change in the position of the power switch 31 can be greatly reduced, which is conducive to the switch driving rod 22 to flexibly drive the switch button 311. In addition, by arranging the double-layer shell structure of the inner mounting shell 34 and the protective cover 35, when an external force impacts the protective cover 35, the impact force that can be transmitted to the power switch 31 is greatly weakened, which can avoid the power switch 31 from being damaged due to impact and vibration. Therefore, the durability of the cover opening and stopping device of the present invention is good.

[0033] Furthermore, if Figure 2 and Figure 3 As shown, the switch assembly 3 includes a support sleeve 33, which is located at the top of the protective cover 35. The switch driving rod 22 is formed with an outer conical step 2201. The upper end of the support sleeve 33 is formed with an inner conical opening 3301 for adapting and abutting the outer conical step 2201. The inner conical opening 3301 is located directly above the switch button 311. In other words, when the cover 2 and the barrel 1 are assembled and connected, the lower end of the switch driving rod 22 presses the switch button 311, and the outer conical step 2201 abuts the inner conical opening 3301. The inner conical opening 3301 thus blocks and supports the switch driving rod 22, preventing the switch driving rod 22 from moving further downward and damaging the power switch 31. The inner conical opening 3301 also guides and positions the outer conical step 2201. The switch driving rod 22 can be made of stainless steel, and the support sleeve 33 is configured as an injection molded part to facilitate absorption of shock and vibration from the switch driving rod 22.

[0034] Furthermore, if Figure 3 and Figure 4As shown, the lower end of the support sleeve 33 is formed with a mounting foot plate 331, and one end of the mounting foot plate 331 is integrally connected with a lower folding plate 332, that is, the lower folding plate 332 is bent downward relative to the mounting foot plate 331, as shown in FIG. Figure 6 As shown, the protective cover 35 is formed with a protective cover top plate 351 and a protective cover outer plate 352, wherein the "outer side" in the "protective cover outer plate 352" refers to the side of the protective cover 35 that is relatively far away from the central axis of the barrel body 1, as shown in FIG. Figure 2 and Figure 3 As shown, the mounting foot plate 331 is abutted against the top plate 351 of the protective cover, and the lower folding plate 332 is abutted against the outer plate 352 of the protective cover. The mounting foot plate 331 and the top plate 351 of the protective cover are connected by corresponding fasteners. For example, corresponding screws are used to pass through the mounting foot plate 331 from top to bottom and screwed to the top plate 351 of the protective cover; by providing the mounting foot plate 331 in combination with the lower folding plate 332 to cover the upper end corners of the protective cover 35, it is conducive to the stable installation of the support sleeve 33 and the protective cover 35, and the displacement of the support sleeve 33 caused by the switch drive rod 22 hitting the support sleeve 33 during daily use can be avoided.

[0035] Furthermore, if Figure 5 As shown, the inner mounting shell 34 is formed with an inner shell outer side plate 342, as shown in FIG. Figure 3 As shown, an opening is provided at one end of the inner mounting shell 34 relatively close to the barrel body 1, and the wire connected to the power switch 31 can be led out through the above opening, as shown in FIG. Figure 1 As shown, the outer side of the barrel body 1 is provided with a wire groove 4, and the wires are introduced into the base of the soymilk maker through the wire groove 4; the outer side plate 342 of the inner shell is formed at one end of the inner mounting shell 34 relatively far away from the barrel body 1, as shown in FIG. Figure 2 As shown, the inner shell outer plate 342 is attached to the inner wall of the protective cover outer plate 352, and the lower folding plate 332, the protective cover outer plate 352 and the inner shell outer plate 342 are connected by corresponding fasteners. For example, Figure 4 As shown, the lower folding plate 332 is formed with two mounting holes, and screws can be used to pass through the above-mentioned mounting holes and the outer plate 352 of the protective cover from the outside to the inside, and the screws are screwed to the outer plate 342 of the inner shell; or the lower folding plate 332, the outer plate 352 of the protective cover and the outer plate 342 of the inner shell are fixedly connected by bolts passing through the above-mentioned mounting holes, thereby further facilitating the stable installation of the support sleeve 33 and positioning the inner mounting shell 34.

[0036] Furthermore, if Figure 5 As shown, a positioning boss 341 is formed on the top of the inner mounting shell 34. Figure 6 As shown, the top plate 351 of the protective cover is formed with a positioning slot 3510. Figure 2 As shown, the positioning boss 341 is adapted to be installed in the positioning slot 3510 upwards, thereby facilitating the stable installation of the inner mounting shell 34 and the protective cover 35, and the support sleeve 33 is covered on the positioning boss 341. Figure 2 As shown, a sealing rubber sleeve 32 is provided in the support sleeve 33. The outer periphery of the sealing rubber sleeve 32 is sandwiched between the inner step of the support sleeve 33 and the upper end of the positioning boss 341. The sealing rubber sleeve 32 can be made of silicone rubber. The lower end of the switch driving rod 22 presses down the middle of the sealing rubber sleeve 32, causing the sealing rubber sleeve 32 to elastically deform. In other words, the lower end of the switch driving rod 22 presses the switch button 311 through the sealing rubber sleeve 32 to prevent water entering the inner conical opening 3301 from contacting the power switch 31. Figure 5 As shown, a switch mounting hole 3411 is formed in the middle of the positioning boss 341. Figure 2 As shown, the power switch 31 is disposed in the switch mounting hole 3411 , and the housing of the power switch 31 can be buckled (or bonded) to the inner mounting shell 34 .

[0037] like Figure 7 As shown, the barrel body 1 of some soymilk makers is provided with an insulating cylinder shell 10. In other words, this type of soymilk maker has a double-shell structure, so that the protective cover 35 is specifically installed on the outer wall of the insulating cylinder shell 10. When the insulating cylinder shell 10 is provided, the insulating cylinder shell 10 can cover the wire groove 4.

[0038] In some embodiments, as Figure 8 As shown, the outer support member is configured as the protective cover 35, and the inner support member is configured as a support crossbar 361. One end of the support crossbar 361 is integrally connected to the inner wall of the protective cover 35. Specifically, one end of the support crossbar 361 can be integrally connected to the inner wall of the protective cover outer plate 352. For example, the support crossbar 361 can be welded to the protective cover 35. The support crossbar 361 is abutted against the lower side of the power switch 31. The structure of the above-mentioned inner support member is relatively simple and easy to manufacture. The number of support crossbars 361 can be more than one. When the switch driving rod 22 presses the switch button 311, the support crossbar 361 supports the outer shell of the power switch 31 from below. The outer shell of the power switch 31 can be bonded to the support crossbar 361.

[0039] In some embodiments, as Figure 9 As shown, the outer support member is set as a protective cover 35, and the inner support member is set as a supporting cross pin 362. One end of the supporting cross pin 362 is connected to the inner wall of the protective cover 35. The supporting cross pin 362 is adapted to pass through the power switch 31. The power switch 31 can be a micro switch. Two through holes are formed on the body of the power switch 31. The supporting cross pin 362 is adapted to be relatively installed in the corresponding above-mentioned through holes. The above structure is relatively simple, easy to manufacture, and is conducive to the rapid positioning and installation of the power switch 31.

[0040] In some embodiments, as Figure 10As shown, the outer support member is configured as a protective cover 35, and the inner support member is configured as a support riser 363. The lower end of the support riser 363 is integrally connected to the inner wall of the protective cover 35, and the upper end of the support riser 363 is in contact with the lower side of the power switch 31. The number of support risers 363 can be more than one. The above structure is relatively simple and easy to manufacture.

[0041] In some embodiments, as Figure 11 As shown, the outer support is set as a protective cover 35, and the inner support is set as a supporting cross plate 364, that is, the supporting cross plate 364 is set horizontally, and the supporting cross plate 364 is connected to the inner wall of the protective cover 35 as a whole. The supporting cross plate 364 is abutted against the lower side of the power switch 31, and the supporting cross plate 364 can be bonded to the outer shell of the power switch 31. The above arrangement is conducive to the power switch 31 and the inner support having a larger contact area, which is conducive to stable support of the power switch 31.
