Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water meters, in particular to a forgetfulness-proof paid water meter for campuses. Background Art
[0002] Smart IC card water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption and transmit water consumption data and settle transactions. Smart IC card water meter is a common paid water meter for campuses. At present, smart IC card water meters are divided into two types: card insertion type and contact type.
[0003] Since the plug-in IC card water meter needs to insert the corresponding IC card into the meter before it can be activated and used, it is inevitable that careless users will forget to take out the IC card after using the water during use. The existing plug-in IC card water meter does not have an anti-forgetting reminder function, which increases the probability of the IC card being used by others, resulting in damage to one's own property.
[0004] Therefore, a campus water meter that prevents forgetting is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide an anti-forgetfulness campus payment water meter in order to solve the above-mentioned problem, thereby improving the problem that the existing campus plug-in IC card water meter does not have an anti-forgetfulness reminder function, which increases the probability of property damage to users.
[0006] The utility model achieves the above-mentioned purpose through the following technical scheme. A campus payment water meter that prevents forgetting includes: an insert-card IC card water meter; an indicating device, wherein the indicating device is fixedly connected to the surface of the insert-card IC card water meter.
[0007] Preferably, the indicating device includes a mounting plate fixedly connected to the surface of the plug-in IC card water meter, a guide port is provided at one end of the mounting plate, a mounting cavity connected to the guide port is provided inside the mounting plate, a rotating shaft is rotatably connected inside the mounting cavity, a sealing plate is fixedly connected to the surface of the rotating shaft, and the sealing plate is in a vertical state at this time, a pressure switch is embedded and installed on the inner top wall of the mounting cavity, an alarm light is electrically connected to the surface of the pressure switch, and one end of the alarm light extends to the outside of the mounting plate, the indicating device can not only continuously emit alarm light and alarm sound during the process of the user inserting the IC card, which can increase the user's attention to the IC card, so as to reduce the probability of the user forgetting the IC card in the plug-in IC card water meter, and when the user takes the IC card out of the indicating device, the indicating device can also automatically close the IC card socket of the plug-in IC card water meter, which can prevent external impurities such as water vapor and dust from entering the IC card socket of the plug-in IC card water meter, thereby achieving the effect of protecting the plug-in IC card water meter.
[0008] Preferably, the vertical cross-section of the installation cavity is fan-shaped, and the fan-shaped angle opening is toward the plug-in IC card water meter. The rotating shaft drives the sealing plate to rotate within the installation cavity to a ninety-degree angle, which can limit the rotation angle of the sealing plate to ensure that the sealing plate is always inside the installation plate.
[0009] Preferably, the vertical cross-sectional dimensions of the installation cavity and the sealing plate are both larger than the vertical cross-sectional dimension of the guide port. At this time, the sealing plate is just in the position to block the guide port. When the sealing plate is in a vertical state, the sealing plate and the installation cavity can jointly block the guide port, thereby achieving the effect of protecting the plug-in IC card water meter.
[0010] Preferably, a guide slope connected to the guide port is provided on the surface of the mounting plate, and the highest point of the guide slope contacts the sealing plate, which can guide impurities blocked by the sealing plate out of the guide port, thereby reducing the retention rate of impurities inside the guide port.
[0011] Preferably, one end of the sealing plate is fixedly connected with a spring sheet in contact with the mounting cavity, and the spring sheet is always in a compressed state. The spring sheet can not only quickly reset the sealing plate after the sealing plate loses its obstruction, but also increase the tightness of the contact between the sealing plate and the mounting cavity when the sealing plate contacts the mounting cavity, thereby improving the protection effect of the plug-in IC card water meter.
[0012] Preferably, the horizontal cross-section of the spring piece is V-shaped, and the opening of the V-shape faces the plug-in IC card water meter, which can ensure that the spring piece can produce corresponding deformation following the rotation of the sealing plate to ensure that the sealing plate can rotate and reset normally.
[0013] Preferably, one end of the pressure switch is electrically connected to a buzzer alarm, and one end of the buzzer alarm penetrates to the outside of the mounting plate, which can emit an alarm sound to the surroundings to enhance the warning effect to the user.
[0014] The beneficial effects of the utility model are:
[0015] 1. The indicator device can continuously emit alarm light and alarm sound when the user inserts the IC card, which can increase the user's attention to the IC card and reduce the probability of the user forgetting the IC card in the card-insertion IC card water meter;
[0016] 2. When the user takes out the IC card from the indicating device, the indicating device can automatically close the IC card slot of the plug-in IC card water meter, which can prevent external impurities such as water vapor and dust from entering the IC card slot of the plug-in IC card water meter, thereby achieving the effect of protecting the plug-in IC card water meter.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] When implementing: Figure 1-4As shown, a forgetfulness-proof campus paid water meter comprises: an insert-card IC card water meter 1; an indicating device 2, wherein the indicating device 2 is fixedly connected to the surface of the insert-card IC card water meter 1, and when installing the mounting plate 21, the guide port 211 needs to be aligned with the socket for inserting the IC card on the surface of the insert-card IC card water meter 1.
[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the indicating device 2 includes a mounting plate 21 fixedly connected to the surface of the plug-in IC card water meter 1, a guide port 211 is provided at one end of the mounting plate 21, a mounting cavity 212 connected to the guide port 211 is provided inside the mounting plate 21, a rotating shaft 22 is rotatably connected inside the mounting cavity 212, a sealing plate 23 is fixedly connected to the surface of the rotating shaft 22, and the sealing plate 23 is in a vertical state at this time, a pressure switch 24 is embedded and installed on the inner top wall of the mounting cavity 212, an alarm light 25 is electrically connected to the surface of the pressure switch 24, and one end of the alarm light 25 passes through the outside of the mounting plate 21; the vertical cross-section of the mounting cavity 212 is fan-shaped, and the fan-shaped angle opening faces the plug-in IC card water meter 1, and the rotating shaft 22 drives the sealing plate 23 to rotate in the mounting cavity 212. The rotatable angle inside the installation cavity 212 is ninety degrees; the vertical cross-sectional dimensions of the installation cavity 212 and the sealing plate 23 are both larger than the vertical cross-sectional dimensions of the guide port 211, and the sealing plate 23 is just in the position of blocking the guide port 211 at this time; the surface of the installation plate 21 is provided with a guide slope 213 connected to the guide port 211, and the highest point of the guide slope 213 is in contact with the sealing plate 23; one end of the sealing plate 23 is fixedly connected to a spring piece 26 in contact with the installation cavity 212, and the spring piece 26 is always in a compressed state; the horizontal cross-sectional shape of the spring piece 26 is V-shaped, and the opening of the V-shape faces the plug-in IC card water meter 1; one end of the pressure switch 24 is electrically connected to a buzzer alarm 27, and one end of the buzzer alarm 27 passes through the outside of the installation plate 21.
[0025] When the utility model is used, the user only needs to insert the IC card through the guide port 211 and plug it into the IC card socket on the card-inserting IC card water meter 1. After the card-inserting IC card water meter 1 detects the information of the IC card, the user can use water normally. In the process of the user inserting the IC card through the guide port 211, the IC card pushes the sealing plate 23 in advance, and the sealing plate 23 rotates upward along the rotating shaft 22. The sealing plate 23 squeezes the pressure switch 24 during the upward movement. After the pressure switch 24 detects the pressure signal, it automatically controls to turn on the alarm light 25 and the buzzer alarm 27 according to the program preset inside it. Before the IC card is not pulled out of the guide port 211, the alarm light 25 and the buzzer alarm 27 can respectively continue to emit alarm light and alarm sound, which can continuously warn the user who uses water, increase the user's attention to the IC card, so as to reduce the probability of the IC card being forgotten in the card-inserting IC card water meter 1;
[0026] When the user pulls the IC card out of the guide port 211, the sealing plate 23 loses its obstruction, and the spring piece 26 can quickly drive the sealing plate 23 to rotate along the rotating shaft 22. The sealing plate 23 is first separated from the pressure switch 24. After the pressure switch 24 detects no pressure signal, it automatically controls to turn off the alarm light 25 and the buzzer alarm 27 according to the program preset inside it, and then the sealing plate 23 continues to rotate until the sealing plate 23 abuts against the inner wall of the installation cavity 212. At this time, the sealing plate 23 cooperates with the inner wall of the installation cavity 212 to block the guide port 211, which can prevent external impurities such as water vapor and dust from entering the guide port 211, so as to reduce the impact on the pressure switch 24 or the IC card socket of the plug-in IC card water meter 1, so as to achieve a good protection effect.
[0027] It should be noted that the card-inserting IC card water meter 1, pressure switch 24, alarm light 25 and buzzer alarm 27 in the above description are all devices with relatively mature application of existing technology. The specific models can be selected according to actual needs. At the same time, the card-inserting IC card water meter 1, pressure switch 24, alarm light 25 and buzzer alarm 27 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
