Detailed Description

To further clarify the technical solutions and effects adopted by the present application to achieve the intended purpose, the following detailed description is given with reference to the accompanying drawings and preferred embodiments according to the present application. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to fig. 1 to 4, the present invention discloses a household appliance with an arc-free coupler, which includes a power supply base 1 and a separate functional unit 2 that can be taken and placed with respect to the power supply base 1, wherein the arc-free coupler is disposed between the power supply base 1 and the functional unit 2, and the arc-free coupler is used to realize the electrical connection between the power supply base 1 and the functional unit 2 without generating an arc, so as to overcome the technical problem that the electric coupler generates an arc in the prior art, thereby facilitating the improvement of the reliability and the safety of the household appliance.

Home appliances are actually represented as different products. For example, when the function unit 2 is a cooking pot, the household appliance corresponds to a separate cooking pot (e.g., a separate wok, a separate electric chafing dish). For another example, when the functional unit 2 is a pot body or an ovenware, the household appliance is an electric kettle or an ovenware correspondingly. For another example, when the function unit 2 is a semiconductor refrigerating sheet, the household appliance is a detachable cold storage tank or a detachable ice cream machine.

As shown in fig. 2 in particular, the function unit 2 includes a function body 21 (for example, the function body 21 is a pot body, or the like, and has different expressions in different products), and an electrical component 22 disposed on the function body 21 (for example, the electrical component 22 is an electric heating component for generating heat or a semiconductor cooling plate for cooling, and has different expressions in different products).

The arcless coupler is arranged between the electrical component 22 and the power supply base 1, so that the electrical component 22 and the power supply source (a storage battery which can be internally arranged in the power supply base 1 or an external power supply) can be electrically connected by using the arcless coupler: when the functional body 21 is placed on the power supply base 1, the non-arc coupler is switched to a closed state, so that a controllable electrical path is formed between the electrical element 22 and the power supply; when the functional body 21 is removed from the power supply base 1, the non-arc coupler is switched to the off state, so that the electrical component 22 is disconnected from the power supply, and the electrical component 22 cannot be powered to work.

As shown in particular in connection with fig. 2 and 3, the arcless coupler comprises in particular: a conductive pin 3 fixedly connected with the electrical component 22; the coupler base 7 is provided with a conductive elastic sheet 71, and the coupler base 7 is provided with a conductive elastic sheet 71; the sliding cover 62 is slidably arranged above the coupler base 7, the sliding cover 62 is provided with a first slot 61 and a second slot 62, and the sliding cover 62 is provided with a first position on the coupler base 7, wherein the first slot 61 and the conductive elastic sheet 71 are staggered to shield the conductive elastic sheet 71, and the first slot 61 and the conductive elastic sheet 71 are arranged oppositely to enable the conductive elastic sheet 71 to be positioned at a second position in the first slot 61; a push switch 81 connected in series between the conductive elastic piece 71 and the power supply; a first trigger 4 for generating a pressing operation to the push switch 81 to switch the push switch 81 from an off state to an on state; a second trigger 5 for pushing the sliding cover 62 to switch from the first position to the second position when being inserted into the second slot 62; the triggering stroke between the first triggering member 4 and the push switch 81 is greater than the triggering stroke between the conductive pin 3 and the conductive spring 71, so that the push switch 81 is switched to the conducting state after the conductive pin 3 is in contact connection with the conductive spring 71.

The position of the lower end of the first trigger 4 is higher than the position of the lower end of the second trigger 5, so that the trigger stroke between the first trigger 4 and the press switch 81 is larger than the trigger stroke between the conductive needle 3 and the conductive elastic sheet 71; or/and the position of the push switch 81 is lower than the position of the conductive elastic sheet 71, so that the triggering stroke between the first trigger 4 and the push switch 81 is larger than the triggering stroke between the conductive needle 3 and the conductive elastic sheet 71.

The coupler base 7 and the push switch 81 are disposed at the bottom of the power supply base 1, and the conductive pin 3, the first trigger 4 and the second trigger 5 are all fixed at the lower side of the functional body 21 of the functional unit 2.

Wherein, the groove wall of the second slot 62 is provided with a first guiding inclined plane 621, and the lower end of the second trigger 5 is provided with a second guiding inclined plane; when the function unit 2 is placed on the power supply base 1, the lower end of the second trigger 5 is inserted into the second slot 62, the first guiding inclined plane 621 and the second guiding inclined plane form an inclined plane matching structure, and the sliding cover 6 slides on the coupler base 7 to switch from the first position to the second position by matching the first guiding inclined plane 621 and the second guiding inclined plane.

And the lower end of the second trigger 5 is arranged downwards relative to the conductive pin 3. The benefits of this arrangement: when the functional unit 2 is placed on the power supply base 1, the lower end of the second trigger 5 is inserted into the second slot 62 of the sliding cover 6 to push the sliding cover 6 to switch from the first position to the second position on the coupler base 7; then, as the function unit 2 approaches the power supply base 1, the conductive pin 3 contacts and connects with the conductive elastic piece 71 located in the second slot 62. At this time, since the push switch 81 is not pressed by the first trigger 4, and is still in the off state, it is ensured that both the conductive elastic sheet 71 and the conductive needle 3 are not electrified when in contact, and no electric contact is realized, thereby preventing the two from being contacted to generate electric arc.

There are various ways to achieve sliding of the sliding cover 6 relative to the coupler base 7. For example, a sliding fit structure (e.g., a guide rail and guide groove fit structure) is provided between the sliding cover 6 and the coupler base 7, and even a spring may be provided between one end of the sliding cover 6 and the coupler base 7 to drive the sliding cover 6 to switch between the first position and the second position relative to the coupler base 7.

The push switch 81 is usually a microswitch which is a normally closed switch having a push end 811, and when the push end 811 of the push switch 81 is pushed by the first trigger 4, the push switch 81 is switched from the off state to the on state only when the push end 811 of the push switch 81 is pushed by the first trigger 4.

In a preferred embodiment, a movable rod 82 is provided at the pressing end 811 of the push switch 81, and the pressing end 811 of the push switch 81 is pressed by the first trigger 4 through the movable rod 82. Because the triggering stroke between the first triggering part 4 and the press switch 81 is large, the first triggering part 4 needs a large stroke for the press switch 81, and the movable rod 82 is arranged to reduce the stroke, so that the pressing operation of the pressing end 811 of the press switch 81 by the first triggering part 4 through the movable rod 82 can be ensured in the process of placing the power unit 2 to the power supply base 1.

In a preferred embodiment, a switch base 9 is further disposed at the bottom of the power supply base 1, a first receiving groove 91 and a second receiving groove 92 are disposed on the switch base 9, the push switch 81 is located in the first receiving groove 91, the movable rod 82 is located in the second receiving groove 92, a lower end of the movable rod 82 abuts against a push end 811 of the push switch 81, and an upper end of the movable rod 82 is exposed out of the second receiving groove 92. This structure ensures that the push switch 81 and the movable lever 82 are stably and reliably connected to each other, which is advantageous for ensuring the reliability of the arcless coupler.

It can be understood that when the push switch 81 is installed on the lower side surface of the power supply base 1, a through groove 11 is provided at the bottom of the power supply base 1 corresponding to the position of the movable rod 82, and the first trigger 4 pushes the upper end of the movable rod 82 through the through groove 11 to push the push switch 81.

Preferably, the first trigger 4 and the second trigger 5 are both integrally formed with the functional body 21. This structure is advantageous for ensuring structural reliability of the home appliance.

In addition, in order to ensure that the arc-free coupler can be switched from the off state to the on state when the functional unit 2 is placed in the power supply base 1, at least the following technical means are adopted:

firstly, the bottom of the power supply base 1 is provided with the bakelite seat 12, the bakelite seat 12 is provided with a first through hole 121 which is over against the conductive pin 3 and a second through hole 122 which is over against the second trigger 5, and the first through hole 121 and the second through hole 122 are utilized to respectively provide guidance for the conductive pin 3 and the second trigger 5.

Secondly, be equipped with a plurality of guide posts 23 at the downside of functional unit 2, correspond in the bottom of power supply base 1 and be equipped with a plurality of pilot holes 13, utilize guide posts 23 to insert the pilot hole 13 that corresponds the position for functional unit 2 can be accurate lay to power supply base 1 on.

In the process of placing the functional unit 2 to the power supply base 1, the lower end of the second trigger 5 is inserted into the second slot 62 of the sliding cover 6 to push the sliding cover 6 to switch from the first position to the second position on the coupler base 7; then, as the function unit 2 approaches the power supply base 1, the conductive pin 3 contacts and connects with the conductive elastic piece 71 located in the second slot 62. At this time, since the push switch 81 is not pressed by the first trigger 4, and is still in the off state, it is ensured that both the conductive elastic sheet 71 and the conductive needle 3 are not electrified when in contact, and no electric contact is realized, thereby preventing the two from being contacted to generate electric arc.
