Description

TECHNICAL FIELD

[0001] The utility model relates to a toy product technical field, especially a drawing toy with infrared grating device, especially a drawing toy with infrared grating trigger device for small area range. BACKGROUND

[0002] Infrared grating is usually used in alarm, and is widely used in places needing safety protection, such as factory equipment, warehouse and airport entrance and exit, etc. It can effectively prevent personnel or object from entering dangerous area, and ensure the safety of personnel and equipment.

[0003] The design principle of infrared grating alarm is: infrared grating adopts active infrared transmission equipment, when foreign matter enters infrared grating, it will block the infrared light beam, thereby generating alarm signal. Specifically, infrared grating alarm sends multiple infrared light beams to receiver through emitter. When foreign matter blocks any light beam for more than 30 milliseconds, receiver will immediately output alarm signal.

[0004] As shown in Figure 1 The principle diagram of infrared grating. The occurrence module includes several uniformly arranged infrared emitters, and the receiving module includes several uniformly arranged infrared receivers. When working, all infrared emitters S1, S2, S3……Sn light up at the same time, and the generated infrared rays are received by corresponding infrared receivers R1, R2, R3……Rn. When foreign matter W enters the grating area, it blocks the infrared rays generated by infrared emitter S1, and generates blocking signal. If the blocking signal time exceeds the set time (usually 30 milliseconds), the corresponding receiver R1 will immediately output alarm signal, and produce sound, light and other alarms.

[0005] Because the conventional infrared emitter adopts infrared LED element, the light emitted by this infrared LED element is not a point light source, and the radius of the radiation range will gradually increase with the increase of the emission distance, forming a fan-shaped radiation surface on the grating surface, and the angle r of the fan-shaped radiation surface is generally 30°-60°. This will cause the following problems: when the light emitted by emitter S1 is blocked by foreign matter W, the light emitted by emitter S2 or even the light emitted by emitter S3 can still reach receiver R1, so that receiver R1 cannot sense the blocking of light signal, and cannot judge the existence of shielding object W.

[0006] In order to overcome the above problems, the traditional solution either uses laser emitter and receiver to directly emit point light to avoid the light emitted by the emitter affecting other receivers, or adds an optical condensing element in front of the traditional LED element to converge the diffused light into point light. In addition, other solutions have also been proposed. See the Chinese utility model patent with patent application number 202310602077.5, which discloses a synchronization method of a safety grating, a safety grating and equipment. The technical solution adopted is that the emitter of the safety grating emits two kinds of infrared modulation signal lights composed of different verification methods in a polling manner, including a first infrared modulation signal light and the rest of the infrared modulation signal light, and the first infrared modulation signal light and the rest of the infrared modulation signal light respectively carry information in different ways; the receiver distinguishes the received infrared modulation signal light in two corresponding verification ways, and according to the information carried by the corresponding infrared modulation signal light, the matching and synchronization of all transmitting tubes and receiving tubes in the emitter and receiver of the safety grating are realized. The technical solution emits two kinds of infrared modulation signal lights composed of different verification methods in a polling manner to realize the matching with the receiver, so that the interference of the corresponding infrared transmitting tubes in other non-emitters and the interference of the non-corresponding transmitting tubes in the emitter can be reduced to a certain extent.

[0007] Whether laser emission, adding a condensing element, or simultaneously emitting two different verification method signal lights, the production cost of the product will be greatly increased, and the technical threshold is high. For some infrared grating used in toys and other products, it is obviously unacceptable for production enterprises. In view of this, the present inventors have continuously thought and proposed the following technical solution. Utility model content:

[0008] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and to provide a drawing toy with an infrared grating device.

[0009] In order to solve the above technical problems, the utility model adopts the following technical scheme: the drawing device comprises: a base and an infrared grating device arranged in the base, the base comprises: a cavity for directly or indirectly storing water, the cavity has an opening above, wherein the infrared grating device comprises: a transmitting module and a receiving module respectively arranged on the left and right sides of the cavity, and a control module in the base, wherein the transmitting module is composed of a plurality of transmitting ends arranged in an array, the receiving module is composed of a plurality of receiving ends arranged in an array, and the transmitting module and the receiving module form an infrared grating area along the interval of the opening; the infrared grating area generates a blocking signal by dripping paint or ink from above the opening, and the control module generates a response according to the blocking signal.

[0016] The drawing toy has the advantages that the structure is simple, and the drawing toy with the water transfer printing effect is provided for children.

[0017] On the other hand, due to the small overall size of the painting toy, the distance between the transmitting end in the transmitting module and the receiving end in the receiving module is usually very small. If the existing traditional design is adopted, signal interference is inevitable. If other methods are adopted, the cost of the product will be too high. After adopting the present utility model, not only will the product cost not be increased, but different responses can also be generated according to the blocking signals at different positions, further enhancing the fun of the toy. Description of the drawings:

[0018] Figure 1 It is a schematic diagram of the working principle of the existing infrared grating device;

[0019] Figure 2 This is a schematic diagram of the working principle of the mid-infrared grating device of the utility model;

[0020] Figure 3 This is a schematic diagram of the top view of the drawing toy in the present invention;

[0021] Figure 4 It is a main structural diagram of the painting toy in the utility model. Specific implementation method:

[0022] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0023] See Figure 2 This is a schematic diagram illustrating the working principle of the infrared grating device of the present invention. The infrared grating device comprises a transmitting module 20 consisting of a plurality of evenly distributed transmitting terminals 2, a receiving module 30 consisting of a plurality of evenly distributed receiving terminals 3, and a control module 40. A gap is formed between the transmitting module 20 and the receiving module 40.

[0024] The infrared light emitted by each transmitting end 2 is directed to a corresponding receiving end 3. For the sake of convenience, each transmitting end is recorded as the 1st, 2nd, 3rd...nth transmitting end, that is, transmitting end S1, S2, S3...Sn; each receiving end is recorded as the 1st, 2nd, 3rd...nth receiving end, that is, receiving end R1, R2, R3...Rn. The infrared light between each transmitting end and the corresponding receiving end constitutes the infrared grating area ( Figure 2 the area indicated by the middle dashed line).

[0025] When the spacing between the transmitting terminals S1, S2, S3, ... Sn is too close, or the spacing between the transmitting module 20 and the receiving module 40 is too small, signal interference will occur as described in the background art. The triggering method of the infrared grating device of the present invention is to overcome these problems and achieve one-to-one signal triggering. The present invention adopts the following scheme:

[0026] Differing from the way that all the emission ends in the emission module in the prior art are continuously lit, the infrared grating is formed in a meshed manner, all the emission ends 2 in the emission module 20 in the utility model will not be lit at the same time, but are lit in turns to emit infrared rays to the receiving end 3. That is, when the emission end S1 is lit, the other emission ends S2, S3, …, Sn are in an extinguished state, when the emission end Sn is lit, the other emission ends S1, S2, S3, … are in an extinguished state. That is, at a certain time point, only one emission end is in a lit state. As long as the time during which the emission end is continuously lit and the interval time between the adjacent two emission sections are short enough, the infrared grating formed in the utility model in a unit time can achieve the same effect as the way that the emission end is continuously lit in the prior art.

[0027] Specifically, if the foreign matter enters the infrared grating area between the emission module and the receiving module, the shortest time during which the infrared rays are blocked is recorded as t; the interval time during which the adjacent two emission ends are lit is T1, and the time required for all the emission ends to complete a round of lighting is recorded as T. When the value of T1 is small enough, T < t is met. During the time t during which the foreign matter enters the infrared grating area, the infrared rays emitted by at least one emission end will be blocked at least once, so that the infrared signal cannot be received by the receiving end corresponding to the emission end, and a blocked signal is generated. The principle is the same as the refresh rate of a screen.

[0028] Of course, in order to realize the one-to-one correspondence between the emission end 2 and the receiving end 3 and avoid the light generated by the emission end Sn being received by other non-receiving ends, when any one emission end 2 is lit, the control module 40 only reads the state of the receiving end 3 corresponding to the lit emission end 2, the control module 40 does not read or ignore the state of the remaining other receiving ends, so that the infrared signal emitted by any one emission end in the emission module is only received by the corresponding receiving end in the receiving module. For example, when the emission end S1 is lit and works, the other emission ends are in an extinguished state. The control module 40 only receives the state of the corresponding receiving end R1, and does not receive the state information of the other receiving ends. Although the emission range of the emission end may radiate to the receiving end R2 at this time, the control module 40 will ignore or cannot receive the signal of the receiving end R2. Finally, when any one emission end Rn is lit, the control module 40 only reads the state of the receiving end Rn corresponding to the lit emission end Rn, so that the one-to-one correspondence between the emission end and the receiving end is realized.

[0029] To enable the control module 40 to only read the status of the receiver Rn corresponding to the lit transmitter Rn, the present utility model can adopt the following method: When any one transmitter is lit, in addition to the receiver corresponding to the lit transmitter being activated, the remaining other receivers are all in the off or disconnected state, so that the control module 40 can only read the status of the activated receiver. Specifically, each receiver is connected to the control module 40 through a switch Q; when the nth transmitter Sn is lit, the switch Qn of the corresponding nth receiver Rn is turned on, and the control module 40 can only read the status of the receiver Rn. At this time, the switches of the remaining other receivers are in the disconnected state and cannot generate blocking signals. The switch can adopt a triode element with low price but fast response speed.

[0030] In a preferred embodiment, different blocking signals can be generated due to the infrared rays emitted by different transmitters being blocked, so that the control module 40 generates different responses. For example, the blocking signals corresponding to each transmitter are denoted as K1, K2, K3... Kn. The control module generates different responses corresponding to each blocking signal. The different responses can be generating different sounds. For example, when the blocking signal is K1, the control module 40 makes the sound generating device generate the pronunciation of "duo"; when the blocking signal is K2, the control module 40 makes the sound generating device generate the pronunciation of "rui". Thus, when the user inserts foreign objects at different positions of the infrared ray grating according to a certain music melody, different blocking signals are generated, and the control module 40 will emit sounds corresponding to the music melody.

[0031] In addition, the foreign object described in the present utility model refers to an object or others having a certain lateral dimension and capable of generating a blocking signal for the infrared ray grating. For substances that are too small in volume, such as dust, filaments, etc., since they cannot trigger the infrared ray grating device of the present utility model to generate blocking signals, they are not regarded as the foreign objects described in the present utility model.

[0032] According to the above, the infrared ray grating device adopting the above triggering method can be applied to toy products. See Figure 3 、 Figure 4 As shown, this is a painting toy with an infrared ray grating device designed by using the above triggering method.

[0033] The painting toy includes: a base 5 and an infrared ray grating device arranged in the base 5. The base 5 includes: a cavity 50 for directly or indirectly storing water, and an opening 500 is provided above the cavity 50. The infrared ray grating device in the base 5 adopts the triggering method of the infrared ray grating device described above, where

[0034] The infrared grating device comprises: a transmitting module 20 and a receiving module 30 arranged on the left and right sides of the cavity 50 respectively, and a control module 40 arranged in the base 5, wherein the transmitting module 20 is composed of a plurality of transmitting ends 2 arranged and distributed, the receiving module 30 is composed of a plurality of receiving ends 3 arranged and distributed, and the transmitting module 20 and the receiving module 40 form an infrared grating area along the interval of the opening 500.

[0035] The use mode of the drawing toy is as follows: a certain amount of water or other liquid is injected into the cavity 50, and then pigments or ink are dripped from different positions above the opening 500. After the pigments or ink fall into the water surface of the cavity 50, the pigments will diffuse under the water molecule tension and water ripple fluctuation, and different colors of pigments are mixed. At this time, a piece of paper is placed into the cavity 50 and soaked in the water, and the pigments in the water are transferred to the surface of the paper to form a watercolor picture.

[0036] In the use process, the infrared grating device is started. When pigments or ink are dripped from above the opening 500, the dripped pigments or ink serve as the foreign matter W in the utility model, and a blocking signal is generated in the infrared grating area, and the control module 40 generates a response according to the blocking signal. The time t mentioned in the foregoing of the utility model refers to the time period from when the foreign matter W reaches the infrared grating area below to when the foreign matter W leaves the infrared grating area above.

[0037] As mentioned above, the blocking signal is used to make the control module 40 generate different sounds. For example, a "duo" mark is marked at the position corresponding to the transmitting end S1, a "rui" mark is marked at the position corresponding to the transmitting end S2, and a "mi" mark is marked at the position corresponding to the transmitting end S3. The user can drip pigments into different areas of the infrared grating according to a piece of music melody, and different pictures will be generated, and the toy can also emit music corresponding to the melody through the loudspeaker 41 (or different buzzer), which is very interesting.

[0038] In the drawing toy of the utility model, a separate water tank 6 can also be used to hold water. Specifically, the cavity 50 has a pull-out opening 53 on the side. The base 5 has a left side plate 51 and a right side plate 52 along the left and right sides of the cavity 50, wherein the left side plate 51 has a left extension 510 extending to the middle, and the right side plate 52 has a right extension 520 extending to the middle. The pull-out opening 53 is formed by the left extension 510 and the right extension 520, and the water tank 6 can be placed in the cavity 50 through the pull-out opening 53. The transmitting module 20 and the receiving module 30 are arranged at the left extension 510 and the right extension 520 respectively, or the transmitting module 20 and the receiving module 30 are arranged below the left extension 510 and the right extension 520 respectively.

[0039] Of course, the above only the specific embodiments of the present application, not to limit the scope of the present application, all equivalent changes or modifications made in accordance with the principles of the present application described in the scope of the present application, should be included in the scope of the present application.
