Description

Technical Field

[0001] This utility model relates to the field of printed electronic components technology, and in particular to a printed switch and an electrical appliance. Background Technology

[0002] In the field of printed electronic components, printed batteries are printed onto a substrate containing an electrical appliance. Conductive ink is then printed onto the substrate to form a conductive layer, which is used to establish an electrical connection between the appliance and the printed battery. However, once this conductive layer cures, the circuit between the appliance and the printed battery is complete, and the battery begins to continuously discharge, thus losing power. To prevent unnecessary power loss, a switching device is needed at the connection point between the appliance and the battery. However, traditional switching devices often use rigid metal springs, which are orders of magnitude larger than the printed layer and cannot withstand bending, stretching, or other mechanical deformations. In other words, traditional switching devices suffer from poor mechanical performance and large size. For these reasons, there is an urgent need for a printed switch that meets the technical requirements of small size and high mechanical performance.

[0003] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content

[0004] The main purpose of this utility model is to propose a printed switch and electrical appliance that meets the technical requirements of small size and high mechanical performance.

[0005] To achieve the above objectives, this utility model proposes a printed switch; Specifically, the printed switch includes: The upper and lower structures are arranged vertically; the upper structure includes a first conductive layer, and the lower structure includes a second and a third conductive layer arranged horizontally, with a separation gap between the second and third conductive layers; the second conductive layer is used for electrical connection with an electrical appliance, and the third conductive layer is used for electrical connection with a printed battery; A first isolation element is located at two side portions of the first conductive layer; the first isolation element is used to disconnect the first conductive layer from the second conductive layer and the third conductive layer. The second isolator is disposed in the separation gap and corresponds to the middle position of the first conductive layer; the second isolator is used to keep the first conductive layer in contact with the second conductive layer and the third conductive layer or to keep them out of contact.

[0006] In one embodiment, the first isolator is disposed on the upper structure and / or the lower structure; and the end face of the second isolator facing the first conductive layer is at a height higher than the end face of the second conductive layer or the third conductive layer facing the first conductive layer.

[0007] In one embodiment, the orthographic projection region of the first conductive layer at least partially overlaps with the orthographic projection region of the second conductive layer, and the orthographic projection region of the first conductive layer at least partially overlaps with the orthographic projection region of the third conductive layer.

[0008] In one embodiment, the upper or lower structure is a composite layer structure, wherein the composite layer structure includes a base layer, a conductive layer and an insulating layer arranged sequentially, and part or all of the first and second isolation members are configured as the insulating layer.

[0009] In one embodiment, the printed switch includes an adhesive structure located between the upper structure and the lower structure; the adhesive structure connects the upper structure and the lower structure to each other.

[0010] In one embodiment, the adhesive structure includes a first adhesive layer with a frame-shaped structure having a notch on one side, the first adhesive layer surrounding the edge of the printed switch so that the internal area of ​​the printed switch is connected to the outside through the notch.

[0011] In one embodiment, the adhesive structure includes a frame-shaped second adhesive layer surrounding the edge of the printed switch to create a sealed internal region of the printed switch; by adjusting the pressure in the internal region of the printed switch or by applying external force to the upper and lower structures, the connection between the first and second conductive layers, and between the first and third conductive layers, can be changed.

[0012] In one embodiment, the printed switch has a rectangular structure, and the second conductive layer and the third conductive layer have a triangular structure; the first isolator has a dotted structure and is respectively disposed on the side of the second conductive layer and the third conductive layer away from the separation gap.

[0013] In one embodiment, the printed switch has a circular structure, and the second conductive layer and the third conductive layer have a semi-circular structure; the first insulating member has an arc structure and is respectively disposed at the arc edge of the second conductive layer and the third conductive layer.

[0014] To achieve the above objectives, this utility model proposes an electrical appliance, which includes a printed switch as described in any of the preceding claims.

[0015] The printed switch provided by this utility model includes a vertically arranged upper structure and a lower structure. The upper structure includes a first conductive layer, and the lower structure includes a horizontally arranged second conductive layer and a third conductive layer. A separation gap is provided between the second and third conductive layers. A first insulating member is used to disconnect the first conductive layer from the second and third conductive layers. In this way, the circuit remains physically disconnected after printing, completely eliminating standby self-discharge and avoiding unnecessary power loss. When power is needed, a slight press or bend allows the first conductive layer to simultaneously connect to the second and third conductive layers, realizing circuit conduction between the electrical appliance and the printed battery.

[0016] This printed switch also includes a second isolator, which has two characteristics: maintaining contact between the first conductive layer and the second and third conductive layers, or breaking contact. Understandably, when the second isolator maintains contact (e.g., using an adhesive, easy-tear adhesive), the first conductive layer is adhered to by its adhesiveness after being pressed, maintaining contact with the second and third conductive layers. In this case, the electrical appliance and the printed battery remain conductive. When the second isolator breaks contact (e.g., using an elastic insulating ink), the first conductive layer is reset by its elasticity after being pressed, breaking contact with the second and third conductive layers. In this case, the electrical appliance and the printed battery quickly disconnect. Manufacturers can select printed switches with different second isolator characteristics based on actual usage requirements.

[0017] Because this printed switch is manufactured using a printing process, its overall thickness is on the same order of magnitude as that of a printed battery. This eliminates the need for millimeter-level switch components such as hard metal springs, and naturally provides mechanical properties such as resistance to bending and stretching, thus meeting the technical requirements of small size and high mechanical performance.

[0024] In the field of printed electronic components, printed batteries are printed onto the substrate of the electrical appliance. Conductive ink is then printed onto the substrate to form a conductive layer, which is used to establish an electrical connection between the appliance and the printed battery. However, once this conductive layer solidifies, the circuit between the appliance and the printed battery is complete, and the battery begins to continuously discharge, thus losing power. To prevent unnecessary power loss, a switching device is needed at the connection point between the appliance and the battery. However, traditional switching devices often use hard metal springs, which are several orders of magnitude larger than the printed layer and cannot withstand mechanical deformation such as bending and stretching. In other words, traditional switching devices suffer from poor mechanical performance and large size.

[0025] To solve the above-mentioned technical problems, this utility model proposes a printed switch and an electrical appliance.

[0026] Please see Figures 1 to 2 In one embodiment of this utility model, the printed switch includes: The upper structure 100 and the lower structure 200 are arranged vertically. The upper structure 100 includes a first conductive layer 110, and the lower structure 200 includes a second conductive layer 210 and a third conductive layer 220 arranged horizontally. A separation gap 230 is provided between the second conductive layer 210 and the third conductive layer 220. The second conductive layer 210 is used to be electrically connected to the electrical appliance 300, and the third conductive layer 220 is used to be electrically connected to the printed battery 400. The first isolation member 510 corresponds to the two side positions of the first conductive layer 110; the first isolation member 510 is used to disconnect the first conductive layer 110 from the second conductive layer 210 and the third conductive layer 220. The second isolation member 520 is disposed in the separation gap 230 and corresponds to the middle position of the first conductive layer 110; the second isolation member 520 is used to keep the first conductive layer 110 in contact with the second conductive layer 210 and the third conductive layer 220 or to keep them out of contact.

[0027] The printed switch provided by this utility model includes a vertically arranged upper structure 100 and a lower structure 200. The upper structure 100 includes a first conductive layer 110, and the lower structure 200 includes a horizontally arranged second conductive layer 210 and a third conductive layer 220. A separation gap 230 is provided between the second conductive layer 210 and the third conductive layer 220. A first insulating member 510 is used to disconnect the first conductive layer 110 from the second conductive layer 210 and the third conductive layer 220. In this way, the circuit remains physically disconnected after printing, completely eliminating standby self-discharge and avoiding unnecessary power loss. When power is needed, only slight pressing or bending is required, so that the first conductive layer 110 can simultaneously connect to the second conductive layer 210 and the third conductive layer 220, realizing circuit conduction between the electrical appliance and the printed battery.

[0028] This printed switch also includes a second isolator 520, which has two characteristics: maintaining contact or disconnecting the first conductive layer 110 from the second conductive layer 210 and the third conductive layer 220. Understandably, when the second isolator 520 maintains contact, for example, if it is a sticky, easy-tear adhesive or a viscous adhesive, after the first conductive layer 110 is pressed, the second isolator 520, located at the center of the first conductive layer 110, uses its adhesiveness to bond the first conductive layer 110, thus maintaining contact with the second conductive layer 210 and the third conductive layer 220. In this case, the electrical appliance 300 and the printed battery 400 remain electrically connected. The duration of this contact between the first conductive layer 110 and the second conductive layer 210 and the third conductive layer 220 is affected by the adhesiveness of the second isolator 520; a lower adhesiveness results in a shorter duration, while a higher adhesiveness results in a longer duration. When the second isolator 520 has the characteristic of being in a disconnected contact state, for example, when the second isolator 520 is set as an elastic insulating ink, after the first conductive layer 110 is pressed, its elasticity is used to reset the first conductive layer 110, thereby disconnecting it from the contact state with the second conductive layer 210 and the third conductive layer 220. At this time, the electrical appliance 300 and the printed battery 400 are quickly disconnected and connected. The manufacturer can select printed switches with different characteristics of the second isolator 520 according to the actual use.

[0029] Because this printed switch is manufactured using a printing process, its overall thickness is on the same order of magnitude as that of a printed battery. This eliminates the need for millimeter-level switch components such as hard metal springs, and naturally provides mechanical properties such as resistance to bending and stretching, thus meeting the technical requirements of small size and high mechanical performance.

[0030] As a preferred embodiment of the above embodiments, refer to Figures 1 to 2The first isolator 510 is disposed on the upper structure 100 or the lower structure 200; and the end face of the second isolator 520 facing the first conductive layer 110 is higher than the end face of the second conductive layer 210 or the third conductive layer 220 facing the first conductive layer 110. With this configuration, the first isolators 510 are disposed in pairs on corresponding positions on both sides of the first conductive layer 110, and can be directly printed on the lower surface of the first conductive layer 110 of the upper structure 100, or on the upper surface of the second conductive layer 210 and the third conductive layer 220 of the lower structure 200. Their main function is to provide two equal-height support points for both ends of the first conductive layer 110. The second isolator 520 is located in the separation gap 230 of the lower structure 200, and its top surface is higher than the top surface of the second conductive layer 210 and the third conductive layer 220, thereby forming a third support point in the middle of the first conductive layer 110. Due to the central support effect of the second insulating member 520, the central part of the first conductive layer 110 of the flexible material is prevented from collapsing to make contact and conduction with the second conductive layer 210 / third conductive layer 220, thereby ensuring the smooth implementation of the technical solution of this application.

[0031] The number of first isolators 510 and second isolators 520 is not limited in this application. In actual operation, the number of first isolators 510 and second isolators 520 can be determined according to the area of ​​the printed switch. As shown in the figure, there are four first isolators 510, which are symmetrically arranged in pairs on both sides of the first conductive layer 110. There are two second isolators 520.

[0032] Furthermore, the first spacer 510 and / or the second spacer 520 adopt a dotted structure. With this configuration, since the volume of the first spacer 510 / second spacer 520 is relatively small, generally 2*2 or 2.5*2.5mm, the dotted structure makes it easier to control the printing quality compared to the square structure when screen printing small patterns. In addition, the printing integrity of the dotted pattern is better, the ink transfer is relatively uniform, and it can avoid clogging and sticking at the corners of the printed pattern.

[0033] As a preferred embodiment of the above embodiments, refer to Figures 1 to 2 The projected area of ​​the first conductive layer 110 at least partially overlaps with the projected area of ​​the second conductive layer 210, and the projected area of ​​the first conductive layer 110 at least partially overlaps with the projected area of ​​the third conductive layer 220. This arrangement ensures that when the upper structure 100 is pressed down, the first conductive layer 110 can simultaneously contact both the second conductive layer 210 and the third conductive layer 220, bridging the two conductor segments originally separated by the gap 230 into a continuous path, thus ensuring the smooth implementation of the technical solution of this application.

[0034] As a preferred embodiment of the above embodiments, refer to Figure 3 The upper structure 100 or the lower structure 200 adopts a composite layer structure 600, wherein the composite layer structure includes a base layer 610, a conductive layer 620, and an insulating layer 630 arranged sequentially. Part or all of the first insulating member 510 and the second insulating member 520 are set as the insulating layer 630. With this configuration, in the actual manufacturing process, part or all of the insulating layer 630 in the composite layer structure 600 can be directly removed to expose the conductive layer. The advantage of this is that it saves some printing processes, and the remaining insulating layer 630 can replace the first insulating member 510 or the second insulating member 520, thereby effectively improving manufacturing efficiency.

[0035] Understandably, as shown in the attached document Figure 3 As shown in (a), when the first spacer 510 is disposed on the upper structure 100 and the second spacer 520 is disposed on the lower structure 200, the upper structure 100 is provided with a base layer 610, a conductive layer 620 (first conductive layer 110), and an insulating layer 630 (first spacer 510) from top to bottom, i.e., the insulating layer 630 is partially removed; the lower structure 200 is provided with a base layer 610 and a conductive layer 620 (second conductive layer 210 and third conductive layer 220) from bottom to top, i.e., the insulating layer 630 is completely removed, wherein the second spacer 520 is printed in the separation gap 230 by screen printing. (See attached diagram) Figure 3 As shown in (b), when both the first spacer 510 and the second spacer 520 are disposed in the lower structure 200, the upper structure 100 is provided with a base layer 610 and a conductive layer 620 (first conductive layer 110) from top to bottom, that is, the insulating layer 630 is completely removed; the lower structure 200 is provided with a base layer 610, a conductive layer 620 (second conductive layer 210 and third conductive layer 220) and an insulating layer 630 (first spacer 510) from bottom to top, that is, the insulating layer 630 is partially removed, wherein the second spacer 520 is printed in the separation gap 230 by screen printing; in other embodiments, the insulating layer 630 of the lower structure 200 can also be partially removed to form the second spacer 520, as shown in the attached figure. Figure 3 As shown in (c). In actual operation, the base layer 610 of the lower structure 200 can be directly taken from the base where the electrical appliance 300 is located.

[0036] As a preferred embodiment of the above embodiments, refer to Figure 4The printed switch includes an adhesive structure 700 located between the upper structure 100 and the lower structure 200. Specifically, the upper and lower edges of the adhesive structure 700 are connected to the base layers 600 of the upper structure 100 and the lower structure 200, respectively. The adhesive structure 700 connects the upper structure 100 and the lower structure 200 to each other. With this configuration, the adhesive structure 700 is positioned between the upper structure 100 and the lower structure 200, with its upper and lower edges directly bonded to the upper and lower base layers 600, respectively. This continuous or partially distributed adhesive layer firmly bonds the upper structure 100 and the lower structure 200 together, preventing interlayer slippage and ensuring that the printed switch remains intact during pressing and bending, thus balancing mechanical strength and electrical reliability.

[0037] Further, refer to Figure 5 The adhesive structure 700 includes a first adhesive layer 710 with a frame-shaped structure having a notch 711 on one side. The first adhesive layer 710 surrounds the edge of the printed switch, allowing the internal area 800 of the printed switch to be connected to the outside through the notch 711. This arrangement uses the notch 711 as an air vent, keeping the internal area 800 of the printed switch in a non-sealed state, thereby preventing the cavity from remaining in a collapsed, conductive state due to negative pressure after vacuum sealing.

[0038] Further, refer to Figure 6 The adhesive structure 700 includes a frame-shaped second adhesive layer 720 surrounding the edge of the printed switch to seal the internal region 800 of the printed switch. By adjusting the pressure within the internal region 800 of the printed switch, or by applying external force to the upper structure 100 and the lower structure 200, the connection between the first conductive layer 110 and the second conductive layer 210, and between the first conductive layer 110 and the third conductive layer 220, can be altered. With this configuration, when the air vent is removed, the internal region 800 of the printed switch is sealed. At this point, air pressure can be used to create a negative pressure on the printed switch (as shown in the attached diagram). Figure 6 (a) shown) or positive pressure (as shown in the attached) Figure 6(b) shows the pressure state, thereby shaping the printed switch to fix its initial state (switch connected or disconnected). There are two switching methods in this case. The first is destructive—the air pressure is eliminated all at once. Since only a very small amount of air (negative pressure) or pre-expanded (positive pressure) remains in the internal area 800, the user only needs to puncture the reserved weak area with a needle tip or pen tip, etc., and the sealed internal area 800 will instantly break and release pressure. The upper structure 100 loses its support and collapses, thus permanently adhering to the lower structure 200. This is suitable for disposable electronic products that need to be activated and discarded or left on standby for a long time. The second is pressure-holding—the sealed air pressure is not changed, but the printed switch itself is elastically deformed by external force. Because the upper structure 100 and the lower structure 200 are printed on a flexible substrate, they have a certain degree of elasticity. When subjected to external forces such as pressing or bending, the internal area 800 is locally flattened, and the upper structure 100 moves down and comes into contact with the lower structure 200, thus completing the circuit. When the external force is removed, the enclosed air causes the printed switch to return to its original shape, the upper structure 100 is pushed up again, and the circuit is broken. Because the air volume is constant, this action of pressing to open and releasing to close can be repeated, realizing a reversible switching function.

[0039] At the same time, Figure 6 In (a), the second spacer 520 has elastic and non-adhesive properties, which can work together with the subsequently injected air pressure to support the first conductive layer 110; or the second spacer 520 has weak adhesion, which can be maintained in contact with the first conductive layer 110, the second conductive layer 210, and the third conductive layer 220 by using auxiliary negative pressure. In this case, the subsequently injected air pressure is greater than the adhesion of the second spacer 520, so as to ensure that the first conductive layer 110 can overcome the adhesion of the second spacer 520 and break contact with the second conductive layer 210 and the third conductive layer 220. Figure 6 In (b), the second spacer 520 is adhesive. At this time, the second spacer 520 can be both insulating and conductive. When the positive pressure is removed or pressure is applied, the adhesiveness helps the first conductive layer 110 to maintain contact with the second conductive layer 210 and the third conductive layer 220.

[0040] As a preferred embodiment of the above embodiments, refer to Figure 7The printed switch has a rectangular structure, and correspondingly, the second conductive layer 210 and the third conductive layer 220 have a triangular structure. The first isolating element 510 has a point structure and is respectively set on the side of the second conductive layer 210 and the third conductive layer 220 away from the separating gap 230. In this way, the printed switch is made into a rectangular structure, while the second conductive layer 210 and the third conductive layer 220 are designed into a triangular structure, with the bases of the two triangles facing each other and the apex angles facing outwards; that is, the hypotenuses of the two triangles extend in a figure-eight shape from the inside to the outside. Correspondingly, only one point-shaped first isolating element 510 is set at each of the apex angles of the two triangles, and a total of two points can form a stable support. The two first isolating elements 510 support the two ends of the first conductive layer 110; when pressed, the first conductive layer 110 flips slightly downward around the two points as a pivot, so that it can make reliable contact with the second conductive layer 210 and the third conductive layer 220 at the same time, realizing conduction; when released, the two points rebound, and the switch is turned off. This minimizes the number of separators, simplifies the printing process, and reduces manufacturing costs.

[0041] As a preferred embodiment of the above embodiments, refer to Figure 8 The printed switch has a circular structure, and correspondingly, the second conductive layer 210 and the third conductive layer 220 have semi-circular structures. The first isolator 510 has an arc structure and is respectively disposed at the arc edges of the second conductive layer 210 and the third conductive layer 220. With this arrangement, the printed switch is made into a perfect circle, and the second conductive layer 210 and the third conductive layer 220 are set into semi-circular structures that can be joined together to form a complete circle. The first isolator 510 is printed with two thin arc lines along the arc edges of the two semi-circles. The arc structure of the first isolator 510 acts like a rubber ring on the edge of the upper circular piece, so that the entire circular surface is evenly raised. When a finger is pressed from any direction, the circular geometry can evenly distribute the pressure to all points on the circumference. The two arc isolators are compressed synchronously, and the central area sinks smoothly. The first conductive layer 110 then contacts the two semi-circular conductive layers simultaneously, avoiding uneven resistance or jitter caused by localized initial contact. After releasing the finger, the arc-shaped isolator rebounds evenly along the circumference, and the disc quickly returns to its initial plane, thus disengaging the switch. Thanks to the symmetry of the circle and the continuous support of the arc, there are no dead angles in the direction of the pressing process, the force is more balanced, and the rebound is more consistent, thereby significantly improving the stability of the feel and the service life.
