Description

Technical Field

[0001] The present disclosure relates to the technical field of stationery, and in particular to a logic pen. Background Art

[0002] Since young children cannot make independent judgments about shapes and quantities, they need the company and guidance of their parents during their learning or practice. In order to reduce the burden on parents and further increase the flexibility and fun of learning for young children, electronic answer pens have appeared on the market. When the pen tip touches the selection box of the correct answer, the answer pen will play music and light up a flashlight to prompt.

[0003] The pen tip of the electronic answer pen is made of two pieces of conductive material, and the corresponding answer frame is also coated with conductive material. The pen body is equipped with a power supply and circuit. Its working principle is that when the conductive pen tip contacts the conductive answer frame, a closed circuit is formed, and the answer pen emits music and lights up the flash light for prompting.

[0004] Since young children have weaker control ability and may not be able to hold the pen in the correct posture, the pen tip often comes into contact with the answer box at an angle. In this case, even if the pen tip is placed in the answer box of the correct answer, the "poor contact" between the pen tip and the answer box will result in a failure to form a closed circuit, so the correct answer prompt sound and prompt light cannot be emitted, which confuses the children and reduces their enthusiasm for learning. Summary of the invention

[0005] The purpose of the present invention is to provide an electronic answer pen that can form a closed circuit and issue a prompt indicating a correct answer even when the pen tip is in contact with an answer frame at an angle, so as to improve the answer accuracy of the answer pen and the enthusiasm of young children in learning.

[0006] To achieve the above objectives, the present disclosure adopts the following technical solutions:

[0007] Provided is a logic pen, comprising a pen holder, one end of the pen holder is provided with a conductive pen head with the lower end exposed outside the pen holder, a control circuit board is provided inside the pen holder, and the control circuit board is electrically connected to the pen head, a power supply and a prompt module respectively;

[0008] The pen tip comprises an inner pen tip and an outer pen tip, which are respectively connected to the control circuit board and have flush lower ends, the inner pen tip and the outer pen tip are not in contact with each other, and the outer pen tip can slide relative to the inner pen tip when subjected to force;

[0009] The inner pen tip is fixed in a fixed groove, a slide groove is provided below the fixed groove, the slide groove is provided with an elastic member, and the top of the outer pen tip abuts against the elastic member and is restricted to slide in the slide groove;

[0010] When the inner pen tip and the outer pen tip contact the conductive surface simultaneously, the control circuit forms a closed circuit, and the prompting module gives a correct prompt.

[0011] Preferably, an insulating isolation sleeve is sleeved outside the inner pen tip and fixed by the isolation sleeve. The outer pen tip is sleeved outside the isolation sleeve and can slide relative to the isolation sleeve. The top of the isolation sleeve is fixed in the fixing groove.

[0012] More preferably, a control switch is further included. The control switch is connected to the control circuit board and is in contact connection with the inner pen tip.

[0013] When the inner pen tip and the outer pen tip contact the conductive surface simultaneously and the control switch is fully triggered due to the force from the inner pen tip, the prompting module gives a correct prompt; otherwise, the prompting module gives an incorrect prompt.

[0014] Preferably, the prompting module includes an audio player and / or an indicator light. The correct prompt and the incorrect prompt respectively correspond to different audio and / or lights of different colors.

[0015] Preferably, a light-transmitting part is provided at the other end of the pen barrel, and the indicator light is arranged in the light-transmitting part.

[0016] Preferably, the light-transmitting part is arranged as a ring. The indicator light includes a first indicator light and a second indicator light that emit lights of different colors respectively. The first indicator light and the second indicator light are respectively arranged on two half-sides of the ring.

[0017] Preferably, a protrusion is provided at the top of the isolation sleeve and protrudes outward. The protrusion is limited in the fixing groove. A sliding piece that protrudes outward is provided at the top of the outer pen tip, and the sliding piece is restricted to slide in the sliding groove.

[0018] Preferably, the elastic member is a spring, and the spring is sleeved outside the isolation sleeve.

[0019] Preferably, the inner pen tip and the outer pen tip are conductive metal pen tips, and the isolation sleeve is a plastic sleeve.

[0020] The technical solution claimed in the present disclosure has achieved the following beneficial effects:

[0021] 1) With the design of a double-layer pen tip, the elastic member is compressed due to the force from the outer pen tip. The outer pen tip can slide towards the pen barrel direction and the inner pen tip gradually exposes. When compressed until the inner pen tip and the outer pen tip contact the surface of the object to be touched simultaneously, if the surface of the object to be touched is conductive, a closed circuit is formed, enabling the logic pen to make a judgment at an inclined angle.

[0022] 2) The outer pen tip is placed on the outside of the inner pen tip, so that by applying force to the outer pen tip at any position and tilt angle, the inner pen tip and the outer pen tip can contact the surface of the object at the same time, further improving the flexibility of the logic pen, the accuracy of judgment, and the enthusiasm of children to learn.

[0023] 3) The setting of the control switch can further improve the accuracy of the logic pen's judgment and has a certain degree of guidance. That is, when it is not clear whether the error prompt is due to a wrong selection or because the control switch is not triggered, the user can continue to apply pressure to the pen tip to finally determine whether the selection is correct.

[0024] 4) The setting of delayed triggering of the circuit control board can avoid the misjudgment of the control circuit board when the inner pen tip and the outer pen tip touch the conductive surface at the same time but fail to continue to trigger the control switch in time due to the pause in the user's action, thereby further improving the judgment accuracy of the logic pen.

Detailed implementation manners

[0035] To make the objectives, technical solutions and beneficial effects of the embodiments in the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, rather than all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0036] Embodiment 1

[0037] As Figures 1-7 shown, the logic pen provided in this embodiment includes a pen shaft 1, and one end of the pen shaft 1 is provided with a conductive pen tip made of conductive metal with the lower end exposed outside the pen shaft. A control circuit board 2 is provided inside the pen shaft 1, and the control circuit board 2 is electrically connected to the pen tip, the power supply 3 and the prompt module respectively.

[0038] The pen tip includes an inner pen tip 4 and an outer pen tip 5 that are respectively connected to the control circuit board 2 and have flush lower ends. The outer pen tip 5 is sleeved outside the inner pen tip 4; the inner pen tip 4 and the outer pen tip 5 do not contact each other, and the outer pen tip 5 can slide relative to the inner pen tip 4 when a force is applied.

[0039] In a preferred solution, the inner pen tip 4 is fixed in a fixing groove 7, a sliding groove 8 is provided below the fixing groove 7, an elastic member 9 is provided in the sliding groove 8, and the top of the outer pen tip 5 abuts against the elastic member 9 and is restricted to slide in the sliding groove 8.

[0040] In a more preferred embodiment, an insulating isolation sleeve 6 is sleeved outside the inner pen tip 4 and fixed therein. The isolation sleeve 6 is preferably made of plastic. The outer pen tip 5 is sleeved outside the isolation sleeve 6 and can slide relative to the isolation sleeve 6. The top of the isolation sleeve 6 is fixed in the fixing groove 7. In the existing logic pen / answer pen, the conductive pen tip is composed of two fixed conductive silica gels / metals. Therefore, only when the front of the pen tip fully contacts the conductive coating on the answer frame can the control circuit inside the pen shell form a closed circuit and prompt that the answer is correct. However, when the pen tip contacts the conductive coating at an inclined angle, the internal circuit cannot form a circuit, and the prompt module cannot issue a correct prompt, resulting in misjudgment of the selection result. In this embodiment, the outer pen tip is sleeved outside the inner pen tip. Applying force to the outer pen tip at any position and inclined angle can compress the elastic member due to the force from the outer pen tip 5. As the outer pen tip 5 slides towards the pen barrel, the inner pen tip 4 inside gradually exposes. When compressed until the inner pen tip 4 and the outer pen tip 5 simultaneously contact the surface of the object to be touched, if the surface of the object to be touched is conductive, a closed circuit is formed, and the prompt module issues a correct prompt. This improves the flexibility of using the logic pen, the accuracy of judgment, and the enthusiasm of children's learning. In an exemplary embodiment, the top of the isolation sleeve 6 is provided with an outward protrusion 15, and the protrusion 15 is limited in the fixing groove 7. The top of the outer pen tip 5 is provided with an outward protruding sliding piece 14, and the sliding piece 14 is restricted to slide in the sliding groove 8. The elastic member 9 is a spring, and the spring is sleeved outside the isolation sleeve 6.

[0041] In addition, the inner pen tip and the outer pen tip can also be arranged left and right, separated by insulating materials in the middle. The outer pen tip is arranged to be slidable relative to the inner pen tip by a similar method as described above. However, this method can only be used at a specific position and inclined angle for the logic pen.

[0042] In an exemplary embodiment, the prompt module includes an audio player 11 or an indicator light 12, preferably including both an audio player and an indicator light. When the inner pen tip and the outer pen tip simultaneously contact the conductive surface, a closed circuit is formed, triggering the audio and lighting up the indicator light at the same time.

[0043] In a preferred embodiment, the other end of the pen barrel 1 is provided with a light-transmitting part 13, and the indicator light 12 is arranged in the light-transmitting part 13. When the indicator light is on, the light shines out from the light-transmitting part 13. In a more preferred embodiment, the light-transmitting part 13 is arranged as a ring, and the two half-sides of the ring respectively accommodate the indicator lights.

[0044] Embodiment 2

[0045] As Figures 1-7As shown in the figure, the logic pen provided in this embodiment includes a pen shaft 1. One end of the pen shaft 1 is provided with a conductive pen tip made of conductive metal with the lower end exposed outside the pen shaft. A control circuit board 2 is arranged inside the pen shaft 1, and the control circuit board 2 is electrically connected to the pen tip, a power source 3, and a prompting module respectively.

[0046] The pen tip includes an inner pen tip 4 and an outer pen tip 5 which are respectively connected to the control circuit board 2 and have flush lower ends. The outer pen tip 5 is sleeved outside the inner pen tip 4; the inner pen tip 4 and the outer pen tip 5 do not contact each other, and the outer pen tip 5 can slide relative to the inner pen tip 4 when stressed.

[0047] In a preferred solution, the inner pen tip 4 is fixed in a fixing groove 7. A sliding groove 8 is arranged below the fixing groove 7, and an elastic member 9 is arranged in the sliding groove 8. The top of the outer pen tip 5 abuts against the elastic member 9 and is restricted to slide in the sliding groove 8.

[0048] In a more preferred solution, an insulating isolation sleeve 6 is sleeved outside the inner pen tip 4 and is fixed inside the isolation sleeve 6. The isolation sleeve 6 is preferably made of plastic. The outer pen tip 5 is sleeved outside the isolation sleeve 6 and can slide relative to the isolation sleeve 6, and the top of the isolation sleeve 6 is fixed in the fixing groove 7.

[0049] In the existing logic pen / answer pen, the conductive pen tip is composed of two pieces of fixed conductive silica gel / metal. Therefore, only when the front of the pen tip fully contacts the conductive coating on the answer frame, the control circuit inside the pen shell will form a closed circuit, and the correct answer will be prompted. However, when the pen tip contacts the conductive coating at an inclined angle, the internal circuit cannot form a circuit, and the prompting module cannot issue a correct prompt, resulting in misjudgment of the selection result. In this embodiment, the outer pen tip is sleeved outside the inner pen tip. Applying force to the outer pen tip at any position and inclined angle can compress the elastic member due to the force from the outer pen tip 5. As the outer pen tip 5 slides towards the pen shaft direction, the inner pen tip 4 inside it gradually emerges. When compressed until both the inner pen tip 4 and the outer pen tip 5 contact the surface of the object being touched at the same time, if the surface of the object being touched is conductive, a closed circuit is formed, improving the flexibility of the logic pen in use, the accuracy of judgment, and the enthusiasm of children's learning.

[0050] In an exemplary solution, the top of the isolation sleeve 6 is provided with an outward protrusion 15, and the protrusion 15 is limited in the fixing groove 7; the top of the outer pen tip 5 is provided with an outward protruding sliding piece 14, and the sliding piece 14 is restricted to slide in the sliding groove 8. The elastic member 9 is a spring, and the spring is sleeved outside the isolation sleeve 6.

[0051] In addition, the inner pen tip and the outer pen tip can also be arranged horizontally, with an insulating material separating the two. A similar method as described above is used to set the outer pen tip to be slidable relative to the inner pen tip. However, this method can only be used obliquely from a specific position for the logic pen.

[0052] In a preferred solution, the logic pen further includes a control switch 10, and the control switch 10 can specifically be a tactile switch. The pins of the tactile switch are connected to the control circuit board and are in contact connection with the inner pen tip 4. When the inner pen tip 4 and the outer pen tip 5 simultaneously contact the conductive surface and the tactile switch is fully triggered due to the force from the inner pen tip 4, the prompting module gives a correct prompt; otherwise, the prompting module gives an incorrect prompt. For example, when the inner pen tip 4 and the outer pen tip 5 simultaneously contact a non-conductive surface (the wrong answer selection box, and no closed circuit can be formed between the pen tip and the control circuit board) and the tactile switch is also triggered, the prompting module gives an incorrect prompt; when the inner pen tip 4 and the outer pen tip 5 simultaneously contact the conductive surface, but the tactile switch is not triggered, the prompting module also gives an incorrect prompt. The setting of the tactile switch can further improve the accuracy of the logic pen's judgment and has a certain guiding effect, that is, when it is not clear whether the incorrect prompt is due to a wrong selection or due to the non-triggering of the tactile switch, the user can continue to apply pressure to the pen tip to finally judge whether the selection is correct.

[0053] In an exemplary solution, the prompting module includes an audio player 11 or an indicator light 12, preferably including both an audio player and an indicator light. The correct prompt and the incorrect prompt respectively correspond to different audio and different colored lights.

[0054] In a preferred solution, the other end of the pen barrel 1 is provided with a light-transmitting part 13, and the indicator light 12 is arranged inside the light-transmitting part 13. When the indicator light is on, the light shines out from the light-transmitting part 13. In a more preferred solution, the light-transmitting part 13 is set as a ring, and the indicator light 12 includes a first indicator light and a second indicator light that emit lights of different colors. For example, the first indicator light can be used as the indicator light when it is correct, and the light color can be green. The second indicator light can be used as the indicator light when it is incorrect, and the light color can be red. The first indicator light and the second indicator light are respectively arranged on two half-sides of the ring.

[0055] In a preferred embodiment, the control circuit board 2 can delay the triggering of the prompt module, and the delay time can be set to, for example, 1 to 2 seconds. That is, when the two conditions of the inner pen tip 4 and the outer pen tip 5 simultaneously contacting the conductive surface and the full triggering of the touch switch do not occur simultaneously or continuously, in order to avoid misjudgment of the control circuit board caused by the user's pause in operation and failure to continue triggering the touch switch in time, after the action of the inner pen tip and the outer pen tip simultaneously contacting the conductive surface is completed, the control circuit board has a waiting time of 1 to 2 seconds. If the touch switch is triggered within this time, a correct prompt sound and a light of the corresponding color are emitted. If the touch switch is not triggered within this time, an incorrect prompt sound and a light of the corresponding color are emitted.

[0056] The above-described embodiments and application examples are only exemplary descriptions of the present disclosure, and do not limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present disclosure shall fall within the protection scope determined by the claims of the present disclosure.
