Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more specifically to a key switch and a juicer using the key switch. Background Art

[0002] A push button switch is usually composed of a button housing and a push button switch installed in the button housing. Its essence is a push button switch. A push button switch is a switch that uses a button to push a transmission mechanism to make the moving contact and the static contact connected or disconnected and realize circuit switching. It is a master control electrical appliance with a simple structure and a wide range of applications.

[0003] In the prior art, the size of the push switch is limited by the size selection of the push switch, especially for push switches used in small household appliances, such as small juicers, coffee machines, etc., the push switches usually selected are relatively small, which makes the size of the push switch set on the juicer smaller in disguise. The small-sized push switch will bring inconvenience to the user, especially for some elderly people at home, the small-sized push switch makes it quite inconvenient to operate. However, if the button shell of the push switch is directly enlarged and lengthened, and matched with a small push switch, the pressing stroke of the trigger switch will not be in place. For example, if the edge of the large-sized button shell is pressed, only the pressing end of the button shell may sink, while the middle part or other places will not sink, resulting in the downward triggering stroke of the button switch not being in place, and the button switch operation cannot be triggered. This setting not only makes the use of household appliances more inconvenient, but also reduces the service life of the button switch if this situation occurs frequently. Utility Model Content

DETAILED DESCRIPTION

[0022] The specific implementation of the embodiment of the utility model is described below with reference to the accompanying drawings.

[0023] Reference Figures 1 to 3 A key switch and a juicer using the key switch, wherein the key switch 10 includes a mounting seat 11 and a button switch 13 arranged in the mounting seat 11. The button switch 13 is a common main control electrical appliance on the market, and its structure is not described here. The button switch 13 is fixedly installed in the middle position of the mounting seat 11. A key housing 12 is pressably covered on the mounting seat 11, and a supporting column 121 is provided on the inner bottom of the key housing 12, and the supporting column 121 is supported by the button switch 13. A reset spring 14 is also provided between the key housing 12 and the mounting seat 11. The reset spring 14 can be a cylindrical reset spring 14 or a tower-shaped reset spring 14. In this embodiment, in order to increase the spring compression stroke, a tower-shaped reset spring 14 is preferably used. The reset spring 14 is sleeved on the button switch 13, and the two ends of the reset spring 14 are respectively supported by the key housing 12 and the mounting seat 11.

[0024] Reference Figure 2 and Figure 3, there is a link frame 15 arranged obliquely between the button housing 12 and the mounting base 11. One side of the link frame 15 is hinged to the button housing 12 or the mounting base 11, and the other side of the link frame 15 is slidably connected to the mounting base 11 or the button housing 12. Preferably, in this embodiment, a hinged card seat 16 is provided on the inner bottom surface of the button housing 12, and a sliding card slot 17 is provided in the mounting base 11. The sliding card slot 17 is composed of a sliding slot 171 and a limiting block 172. The limiting block 172 is fixed above the sliding slot 171, and the link frame 15 is clamped between the sliding slot 171 and the limiting block 172. There are two sliding card slots 17, and the two sliding card slots 17 are respectively arranged at both ends in the mounting base 11. The link frame 15 is in a U shape, and two folding rods (not marked in the figure) extend laterally from both ends of the open side of the U-shaped link frame 15. The folding rods are slidably clamped in the sliding card slots 17, and the other side of the U-shaped link frame 15 is rotatably clamped in the hinged card seat 16.

[0025] When the button switch 10 of the present utility model presses the button housing 12, due to the cooperation between the link frame 15 and the sliding card slot 17, it plays a guiding role in restricting sliding, so that no matter which position on the button housing 12 is pressed, the button housing 12 can be driven by the link frame 15 to be pressed downward as a whole, fully pressing the button switch 13. Thus, the size of the button housing 12 does not need to match the size of the button switch 13. The manufacturer can配套 use a large-sized button housing 12 according to requirements without worrying that the edge of the large-sized button housing 12 cannot trigger the button switch 13 when pressed. Therefore, this button switch 10 has the advantages of strong structural versatility, wide application range, and stable pressing.

[0026] Refer to Figure 1 and Figure 4 , the juicer includes a machine base 20 and a mixing cup 30 detachably connected to the machine base 20, and the button switch 10 is arranged on the machine base 20. An installation groove 21 is provided on the machine base 20, and a rotating motor 22 is provided in the machine base 20. The rotating motor 22 is located below the installation groove 21. The mixing cup 30 includes a rotating base 31 and a cup body 32 screwed onto the rotating base 31. The rotating base 31 is installed in the installation groove 21, and several assembly blocks 211 are provided in the installation groove 21. The rotating base 31 is provided with several assembly slots 311 that cooperate with the assembly blocks 211. In this embodiment, the mixing cup 30 is detachably clamped to the machine base 20 through the cooperation between the assembly blocks 211 and the assembly slots 311.

[0027] Refer to Figure 4A bearing seat 33 is fixedly provided on the rotating base 31, a rotating shaft 34 is passed through the bearing seat 33, a stirring blade 35 is installed on the upper end of the rotating shaft 34, and the lower end of the rotating shaft 34 is connected to the rotating motor 22 through a motor clutch 23. In this embodiment, the motor clutch 23 is composed of an upper and lower clutch, which is a conventional motor clutch 23 on the market, and will not be further described here.

[0028] When the juicer is in use, by setting the above-mentioned push button switch 10, the size of the button housing 12 of the push button switch 10 can be increased, which is convenient for users to operate the juicer. When in use, any position of the button housing 12 can be pressed at will without worrying about not pressing it in place, thereby reducing electrical losses caused by unstable contact of the juicer switch circuit and extending the service life of the juicer.

[0029] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
