Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a safety glass cup. Background Art

[0002] Glass is a kind of drinking utensil widely used in families, restaurants, etc., because the materials used are hygienic and safe, do not cause harm to the human body, are environmentally friendly and sustainable, have good heat preservation effects, have a long service life, and are relatively inexpensive. Existing glass cups are generally divided into heat preservation glass cups and non-heat preservation glass cups, as well as glass cups with or without covers.

[0003] Although the existing glass cups meet the needs of use to a certain extent, their functions are relatively simple. For example, for a glass cup with a lid, when the lid is not properly closed (and there is no connection between the lid itself and the upper end of the glass cup, even if the lid is properly closed, there is a possibility that the lid and the glass cup will separate), there is a possibility that the upper end of the glass cup will separate and fall to the ground and be damaged (for example, the table on which the glass cup is placed shakes due to various reasons, etc.). In addition, the existing glass cups do not have a reminder function. When the user accidentally puts the glass cup on the edge of the table, there is also a possibility that it will slide from the table to the ground and be damaged. Finally, as the technology of industrial products matures, the competition between the same products and different manufacturers is becoming increasingly fierce, so it is particularly necessary to provide a glass cup that can effectively combine the lid and the glass cup body and can remind the user when the glass cup is on the edge of the table. Utility Model Content

[0004] In order to overcome the disadvantages of existing glass cups due to structural limitations as mentioned in the background, the utility model provides a safety glass cup based on a glass cup body, which not only has the functions of an ordinary glass cup, but also can conveniently separate and effectively combine the cover and the glass cup body through a snap-on structure, and can make a sound to remind the user when the glass cup body is located at a certain position on the table edge, thereby reducing the probability of damage to the glass cup body and the cover, and improving the market competitiveness of the product.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A safety glass comprises a glass body, a component box, a photoresistor and a spring clip, and is characterized in that it also has a control circuit and an alarm circuit; the component box is installed at the lower end of the glass body, a plurality of fixing grooves are distributed at the lower end of the cover of the glass body, there are a plurality of spring clips, the lower end of each spring clip is an elastic arc structure, and the upper ends of the plurality of spring clips are respectively installed in the plurality of fixing grooves at the lower end of the cover; there is a limit ring at the upper end of the glass body, and a plurality of spring clips at the lower end of the cover are clamped on the limit ring; there are a plurality of photoresistors, and the plurality of photoresistors and the control circuit and the alarm circuit are installed in the component box; the power output end of the control circuit is electrically connected to the power input end of the alarm circuit, and the two ends of the plurality of photoresistors are electrically connected to the two signal input ends of the alarm circuit.

[0007] Furthermore, the outer diameter formed by the upper ends of the plurality of retaining springs is smaller than the inner diameter of the limiting ring, and the outer diameter formed by the arc-shaped parts of the lower ends of the plurality of retaining springs is larger than the inner diameter of the limiting ring.

[0008] Furthermore, the light-receiving surfaces of the plurality of photoresistors are spaced apart from each other and are located outside the lower end of the component box.

[0009] Furthermore, the control circuit includes electrically connected resistors and transistors, and a force-sensitive resistor, one end of the first resistor is connected to one end of the second resistor and one end of the force-sensitive resistor, the other end of the second resistor is connected to the base of the first transistor, the collector of the first transistor is connected to the base of the second transistor, the other end of the first resistor is connected to the emitter of the first transistor, and the other end of the force-sensitive resistor is connected to the emitter of the second transistor.

[0010] Furthermore, the force-bearing surface of the force-sensitive resistor is located outside the lower end of the component box.

[0011] Furthermore, the alarm circuit includes an electrically connected resistor, a transistor, and a buzzer, one end of the resistor is connected to the base of the transistor, and the collector of the transistor is connected to the positive power input end of the buzzer.

[0012] Compared with the prior art, the utility model has the following beneficial effects: (1) the utility model is based on the glass body and has the functions of an ordinary glass. Since the glass body and the cover are connected together by multiple clip springs, the cover and the glass body can be easily separated and effectively combined. The cover is relatively difficult to separate from the glass body without the user removing the cover upwards, which reduces the probability of the cover and the glass body being separated and broken; (2) under the action of the control circuit, when the user drinks water normally, the alarm circuit does not work, which prevents false alarms. Under the joint action of multiple photoresistors and the alarm circuit, when the user puts the glass body at a certain position on the edge of the table, any photoresistor does not touch the table, or when the glass body is placed on a foreign object on the table (for example, one side of the glass body is placed on the pad of the table, and the glass body is tilted), the buzzer can sound to remind the user, which reduces the probability of the glass body falling and being damaged. The utility model improves the market competitiveness of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 , 2 As shown in the figure, the safety glass includes a battery G1, a glass body 1 with a cover 101, a component box 2, a charging socket CZ, a photoresistor RLN, a spring clip 3, and also has a control circuit 4 and an alarm circuit 5; the component box 2 is a hollow structure, and a circle of fixing ring 21 is arranged on the outer side of the upper end of the component box 2. The fixing ring on the upper part of the component box 2 is tightly sealed on the outer side of the lower end of the glass body 1. The lower end of the cover 101 is annularly provided with a plurality of rectangular fixing grooves 102 at a certain distance, and the spring clip 3 has three pieces, each spring clip 3 The upper end of the cover (with elasticity) is a rectangular structure and the lower end is a semicircular arc structure 31. The upper ends of the three spring plates are respectively tightly fitted and fixed in multiple fixed grooves 102 at the lower end of the cover; the upper end of the glass cup body has a circle of integrally formed limiting ring 103 with an inner diameter smaller than the inner diameter of the glass cup body, and the cover is clamped on the limiting ring 103 through the lower ends of the three spring plates 3 at the lower end; there are multiple photoresistors RLN, and the multiple photoresistors RLN and the charging socket CZ, the control circuit 4, and the alarm circuit 5 are installed on the circuit board 2 in the component box.

[0017] Figure 1 , 2As shown in the figure, the outer diameter of the upper ends of the three elastic springs 3 (stainless steel) is smaller than the inner diameter of the stop ring 103, and the outer diameter of the arc-shaped parts 31 of the lower ends of the three springs is larger than the inner diameter of the stop ring 103. After the cover 101 and the stop ring 103 of the glass body are combined, the arc-shaped parts 31 of the lower ends of the three springs are stuck at the lower end of the stop ring 103. The light-receiving surfaces of the multiple photoresistors RLN are spaced annularly (3 mm) and are respectively located outside the opening at the lower end of the component box 2 (the opening and the side end of the photoresistor RN are in a sealed state). The control circuit includes resistors R1 and R2, transistors Q2 and Q3, and a force-sensitive resistor RT connected via circuit board wiring. One end of the first resistor R1 is connected to one end of the second resistor R2 and one end of the force-sensitive resistor RT. The other end of the second resistor R2 is connected to the base of the first transistor Q2, the collector of the first transistor Q2 is connected to the base of the second transistor Q3, the other end of the first resistor R1 is connected to the emitter of the first transistor Q2, and the other end of the force-sensitive resistor RT is connected to the emitter of the second transistor Q3. A rubber pad 6 is glued to the force-bearing surface of the force-sensitive resistor RT, and the lower end of the rubber pad 6 is lower than the lower end of the component box 2. After the glass body 1 is placed on the table, the lower end of the rubber pad 6 is compressed and is in the same plane as the lower end of the glass body 1 (the gravity of the glass body effectively acts on the force-sensitive resistor RT). The alarm circuit includes a resistor RN, a transistor QN, and a buzzer BN connected via circuit board wiring. One end of the resistor RN is connected to the base of the transistor QN, and the collector of the transistor QN is connected to the positive power input end of the buzzer BN. The charging socket CZ can also be replaced by a wireless charging transmitter and receiver module. The wireless charging receiver module is installed at the lower end of the component box 2, and the two power output ends and the two poles of the battery G1 are connected via wires. The wireless charging transmitter module is installed separately at the upper end of a component box A, and the glass cup body is placed at the upper end of the component box A for charging.

[0018] Figure 1 , 2 As shown in the figure, the two poles of the battery G1 and the two ends of the charging socket CZ are connected by wires, and are connected in series with the power input end of the control circuit, the emitter of the transistor Q3 and the emitter of the transistor Q2 by wires, the collector of the power output end of the control circuit, the collector of the transistor Q3 and the emitter of the transistor Q2, and the positive power input end of the buzzer BN and the emitter of the transistor QN are connected by wires, one end of the multiple photoresistors RN and the collector of the positive power output end of the control circuit, the collector of the transistor Q3, and the other end of the multiple photoresistors RN and the other end of the resistor RN at the power input end of the alarm circuit are connected by wires. The handle of the power switch S1 and the jack of the charging socket CZ are respectively located outside the two openings at the front end of the component box 2.

[0019] Figure 1 , 2As shown in the figure, the present invention is based on a glass body 1 and has the drinking function of an ordinary glass. Since the glass body 1 and the cover 101 are connected together by three clip springs 3, the cover 101 and the glass body 1 can be easily separated and effectively combined. On the basis that the user does not remove the cover 101 upwards, the cover 101 is relatively difficult to separate from the glass body 1, reducing the probability of the cover 101 and the glass body 1 being separated and broken (when the cover 101 and the glass body 1 are combined, due to the elastic effect, the arc-shaped parts 31 at the lower ends of the three clip springs move inward along the limiting ring 103 and the inner diameter becomes smaller, so that the cover 101 can be inserted into the glass body 1). At the lower end of the limiting ring 103, after the cover 101 is located at the lower end of the limiting ring, the arc-shaped parts 31 at the lower ends of the three clip springs move outward under the elastic force, and the upper ends of the arc-shaped parts are clamped on the lower side end of the limiting ring 103. In this way, the cover and the glass body will not separate without the user's upward external force; when the user lifts the cover 101 vertically upward with his hands, the arc-shaped parts 31 at the lower ends of the three clip springs move inward along the limiting ring 103, and the inner diameter becomes smaller, and then separate upward from the limiting ring 103, so that the cover 101 can be easily removed. When the battery G1 is out of power, the external 12V power charger plug can be inserted into the charging socket CZ to charge the battery G1 (in the wireless charging method, the glass body 1 is placed outside the upper end of the component box A, and the wireless charging transmitting module transmits a wireless charging energy signal. The wireless charging receiving module at the lower end of the component compartment receives the energy signal and converts it into a DC power supply to charge the battery G1). After turning on the power switch S1, the control circuit is powered on (the standby current is only about 8μA). When the user does not hold up the glass body 1 with his hands to drink water, the lower end of the glass body 1 touches the table, the pressure on the force-sensitive resistor RT is relatively large, its resistance value is relatively small, and the voltage divided with the resistor R1 is small. In this way, the 12V power supply output by the battery G1 is divided by the force-sensitive resistor RT and the resistor R1, and the resistor R2 reduces the voltage and limits the current to enter the base of the transistor Q2, which is higher than 0.7V. The transistor Q2 is turned on and the collector outputs a low level and enters the base of the transistor Q3. The transistor Q3 is turned on and the collector outputs a high level and enters one end of the multiple photoresistors RLN and the power input end of the alarm circuit. The multiple photoresistors RLN and the alarm circuit are powered on (the total standby current is only about 13μA), which is ready for detecting the safe placement of the glass body. When the user holds up the glass body 1 to drink water, the lower end of the glass body 1 no longer touches the table, the pressure on the force-sensitive resistor RT is relatively small, its resistance value is relatively large, and the voltage divided between it and the resistor R1 is large. In this way, the 12V power supply is divided by the force-sensitive resistor RT and the resistor R1, and the resistor R2 reduces the voltage and limits the current to enter the base of the transistor Q2 below 0.7V. The collector of the transistor Q2 is cut off and no longer outputs a low level to enter the base of the transistor Q3. The collector of the transistor Q3 is cut off and no longer outputs a high level to enter one end of the multiple photoresistors RLN and the power input end of the alarm circuit. The multiple photoresistors RLN and the alarm circuit lose power, preventing the buzzer BN from falsely alarming when the user holds up the glass body 1 to drink water.

[0020] Figure 1 , 2 As shown, when the glass body 1 is placed on the table and is not located at the edge of the table, no photoresistor RLN is located under the side of the table to receive light, or one side of the glass body is not placed on the cutlery pad on the table, etc., the glass body is not tilted, all photoresistors RLN are in contact with the table and are not exposed to light, and the resistance values ​​of all photoresistors RLN are relatively large. In this way, the 12V power supply enters the base of the transistor QN through multiple photoresistors RLN and resistor RN with voltage reduction and current limiting, which is lower than 0.7V, and the transistor QN will not be turned on. Then, the buzzer BN will not be powered on to make a sound, indicating that the placement of the glass body 1 is normal. When, for various reasons, the glass body 1 is placed on the table and located at the edge of the table, any one or more photoresistors RLN are located under the table and exposed to light, or one side of the glass body is placed on the tableware pad, etc., the glass body is tilted, and the corresponding one or more photoresistors RLN and the table are not in contact with light, and the resistance value of the corresponding one or more photoresistors RLN is relatively small, so that the 12V power supply enters the base of the transistor QN through the corresponding one or more photoresistors RLN and the resistor RN, and the voltage is reduced and the current is limited to be higher than 0.7V. The transistor QN will conduct the collector to output a low level and enter the negative power input terminal of the buzzer BN. Then, the buzzer BN will be powered and sound, indicating that the placement of the glass body 1 is abnormal. After hearing the prompt sound, the user can correct the position of the glass body 1, reducing the probability of the glass body tipping over and falling to the ground and being damaged. This new type also improves the market competitiveness of the product. Figure 2 As shown, the resistance values ​​of resistors R1, R2, and RN are 10K, 1.8K, and 100Ω respectively; the battery G1 is a lithium battery of model 12V / 2Ah; the transistors Q2 and QN are NPN transistors of model 9013; the buzzer BN is a finished active continuous sound buzzer alarm of model FM12V; the transistor Q3 is a PNP transistor of model 9012; the force sensitive resistor RT is a finished film pressure sensor of model FSR402; the photoresistor RLN is a photoresistor of model 5506.
