In one embodiment, the aforementioned dispensing valve includes a flow control valve, a pressure control valve, or a disk seat valve.

The purpose, technical content, features and effects achieved by the present invention will be more readily understood by the detailed description of the embodiments.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only directions referring to the additional drawings. The drawings in the present invention are intended to illustrate the functional relationship between the various devices and the various elements, and the shapes, thicknesses, and widths are not drawn to scale.

In one aspect, with reference to Figure 1, the present invention provides a fluid dispensing control device 11 for a fluid dispenser 10 that receives a fluid and controls the delivery of fluid. The fluid distribution control device 11 includes a microcomputer inductance detector 111 for sensing a motion state of the fluid dispenser 10, wherein the microcomputer inductance detector 11 sends an abnormal signal when the motion state is an abnormal state. The fluid distribution control device 11 further includes a cutoff controller 112. The cutoff controller 112 sends a control signal according to the abnormal signal to control the dispensing of the dispensing valve cutoff fluid. The abnormal state may be set as needed, such as, but not limited to, one or more of the following may be defined as an abnormal state: when the fluid dispenser 10 is in a free fall state, or the swing angle of the fluid dispenser 10 is greater than a swing threshold The value, or the fluid dispenser 10 is in an impact state, or the speed change of the fluid dispenser 10 is greater than an acceleration threshold, or the action of the predetermined fluid dispenser 10, and the like. For example, when the fluid dispenser 10 is in a free fall state, the microcomputer inductor 111 senses an abnormal state of the free fall state, and sends an abnormal signal to the cutoff controller 112. The cutoff controller 112 sends a control signal based on the abnormal signal to cut off the dispensing of the fluid. The present invention has the effect of shutting off fluid distribution according to an abnormal state, which is not the prior art.

The fluid dispensed can be a liquid or a gas. Further, liquids such as, but not limited to, may include water, fuel oil, chemical liquids, solvents, coolants, bleaches, cleaning solutions, and the like. The gas may include, for example but not limited to, a combustible gas, a chemical gas, an inert gas, or the like.

Delivery valves such as, but not limited to, may include flow control valves, pressure control valves, disk seat valves, and the like.

In one embodiment, the microcomputer inductive detector 111 can include an accelerometer, an altimeter, an angular velocity meter, a gyroscope, a gravimeter, or both, or a combination of two or more. For example, when the determination of the abnormal state is determined based on the acceleration or speed state of the fluid dispenser 10, the microcomputer inductance detector 111 may correspondingly include an accelerometer. For another example, when the determination of the abnormal state is determined according to the change in the height of the fluid dispenser 10, the microcomputer inductance detector 111 may correspondingly include an altimeter. For another example, when the determination of the abnormal state is determined according to the swing of the fluid dispenser 10, the microcomputer inductance detector 111 may correspondingly include an angular velocity meter or include a gyroscope. For another example, when the determination of the abnormal state is determined according to the gravity state of the fluid dispenser 10 (for example, whether it is free to fall), the microcomputer inductance detector 111 may also include a gravimeter. The user can determine the type of the microcomputer inductance detector 111 according to the requirements. Of course, if the abnormal state is judged by more than one type, the user can determine the selected combination of the microcomputer inductance detector 111 according to the demand.

As previously mentioned, for example and without limitation, one or more of the following may be defined as an abnormal state: when the fluid dispenser 10 is in a free fall state, or the swing angle of the fluid dispenser 10 is greater than a swing threshold, or The fluid dispenser 10 is in an impact state, or the speed change of the fluid dispenser 10 is greater than an acceleration threshold, or the action of the predetermined fluid dispenser 10, and the like. The aforementioned free fall state means that the fluid dispenser 10 is in a falling state, for example, the grease gun is loosened from the fuel filler port, or falls, for example, the shower head is detached from the pylon, and the like, indicating that it is necessary to forcibly cut off the distribution of the fluid. In addition, the swing angle of the fluid dispenser 10 is greater than a swing threshold, such as may be that the fluid dispenser 10 is disengaged from the rack of the cart so that it oscillates before transporting the cart, again indicating the need to force the delivery of the fluid. In addition, for example, when the switching function of the fluid dispenser 10 itself fails, the dispensing of the fluid must be forcibly cut off, and according to the setting of the user, the fluid dispenser 10 can be swung according to a specific mode, for example, a certain number of swings exceeding a swing threshold. When the microcomputer inductance detector 111 senses the swing of the specific number of times, it sends an abnormal signal to cut off the delivery of the fluid. Further, when the fluid dispenser 10 is in an impact state, it is apparent that this also belongs to an abnormal state and indicates that it is necessary to forcibly cut off the delivery of the fluid. At the moment of impact, the microcomputer inductance detector 111 senses a very high acceleration change, so an acceleration threshold can be set, and when the microcomputer inductance detector 111 senses an acceleration change exceeding the acceleration threshold value. , it can be determined as abnormal and forced to cut off the distribution of the fluid. Each of the modes exemplified above can be correspondingly designed in consideration of the sensing error of the microcomputer inductance detector 111; for example, it is determined whether the fluid dispenser 10 is in a free fall state, and it is not necessary to sense the acceleration accurately. The ground is equal to the gravitational acceleration G, and only the sensed acceleration needs to be close to G.

In addition to the above determinations, time considerations may also be added, such as, but not limited to, the abnormal state needs to last for more than a certain time interval, or needs to occur within a certain time interval. In one embodiment, when the microcomputer inductive detector 111 senses the fluid dispenser 10 for a certain time interval, it continues to be in an acceleration state corresponding to the gravitational acceleration G (such as, but not limited to, when the accelerometer senses an acceleration of G or When the G is approached, or when the gravimeter cannot sense gravity or only a slight amount of gravity is felt, the fluid dispenser 10 is judged to be in the aforementioned free fall state. In another embodiment, when the microcomputer inductance detector 111 senses that the height drop of the fluid dispenser 10 during a certain time interval is greater than a height threshold, it is determined that the fluid dispenser 10 is in the aforementioned free fall state. (In the former case, the time at which the gravitational acceleration G is required to continue exceeds the set corresponding time interval, and in the latter case, the time for the height drop needs to be shorter than the set corresponding time interval.)

For the specific time interval described above, the length can be weighed according to factors that need to be considered. For example, it can be considered whether the specific time interval is long enough, and it is enough to correctly judge the continuous free fall state; on the other hand, it is also considered that when the specific time interval is set too long, the fluid loss may be excessive or even increase the risk. . Based on these factors, the user can determine the appropriate length for this particular time interval.

In the foregoing, one of the definitions describing the abnormal state may be: the action of the preset fluid dispenser 10. The operation of the predetermined fluid dispenser 10 may be, for example, but not limited to, the operation of "swinging the fluid dispenser 10 in a particular mode" as described above. In one embodiment, the action of the preset fluid dispenser 10 can be a predetermined motion path, such as an operation gesture (such as but not limited to a circular motion exceeding a certain angle); in another embodiment, the preset motion The action of the fluid dispenser 10 can also be a tapping action. When the function of the fluid dispenser 10 fails, the dispensing of the fluid must be forcibly cut off, and the user can shut off the dispensing of the fluid by operating a gesture or a tapping action. The tapping action may be, for example but not limited to, a single or a plurality of taps; if there are more than three taps, the length of the interval between the taps may be the same or different (if different, the avoidance may be avoided) The water head in the pipeline is confused with the resonance sound, which is a fixed frequency).

Figure 2 shows another embodiment of the invention. As shown, the fluid dispenser 20 includes a fluid delivery control device 21 that includes a micro-generator (micro) in addition to the microcomputer-inductance detector 111 and the cut-off controller 112 of the previous embodiment. Generator 213, the micro-generator 213 is in communication with the fluid distribution line 12 to convert the generated energy by the flow energy of the fluid in the fluid distribution line 12 to supply power to the microcomputer inductance detector 111 and/or the cut-off controller 112. The micro-generator 213 converts the flow energy in the shunt tube to generate electrical energy by communicating with one of the fluid distribution lines 12 of the shunt tube. Flow energy can include pressure, impulse, kinetic energy, speed, temperature, and the like. Since the microcomputer inductance detector 111 and the cut-off controller 112 only need to work when the fluid flows, and do not need to consume a lot of electric energy, the electric energy generated by the micro-generator 213 is sufficient to be used; but if necessary, the electric energy storage can be set. The device is such as a capacitor or the like (not shown). In the embodiment of Fig. 2, the fluid distribution control device 21 can be powered by the micro-generator 213, which eliminates the cost, volume and weight of the relevant parts of the battery or external power. However, it is still within the scope of the present invention to use a battery or external power without powering the micro-generator 213.

Figure 3 shows another embodiment of the invention. In another aspect, the present invention provides a fluid dispensing anomaly monitoring device 13 for a fluid dispenser 30 that receives a fluid and controls the output of the fluid. The fluid dispensing anomaly monitoring device 13 includes: The abnormal state sensor 131 is configured to sense a motion state of the fluid dispenser, wherein when the motion state is an abnormal state, the abnormal state sensor 131 sends an abnormal signal; and a micro-generator 213, the micro-generator 213 The flow of fluid can be converted to generate electrical energy for powering the abnormal state sensor 131. The difference between this embodiment and the previous embodiment is that in this embodiment, the delivery of the cutoff fluid is not required, and only the abnormal signal needs to be issued, so the cutoff controller 112 can be omitted. Abnormal signals such as, but not limited to, can be used to issue warning sounds, warning lights, warning texts, and/or wireless, wired, network, etc. to the remote end, or both, or both, at the site of fluid dispensing.

The difference between this embodiment and the embodiment of Fig. 1 is that the microcomputer inductance detector 111 and the cut-off controller 112 are separately installed in the fluid dispenser 40, and do not constitute an integrated module.

The aforementioned fluid dispensers 10, 20, 30, 40 may be, for example but not limited to, a showerhead, a spray gun, a delivery gun, or a special dispensing gun.

Figure 5B shows the flow control valve shutting off fluid delivery based on the control signal. 5A and 5B are only examples. When the dispensing valve is a flow control valve, other embodiments may be used to cause the flow control valve to shut off fluid delivery according to the control signal.

Referring to Figures 6A and 6B, an embodiment in which the dispensing valve is a pressure control valve is shown. In Figure 6A, the pressure control valve receives fluid on one side and fluid on the other side. When the microcomputer inductance detector 111 senses an abnormal state, an abnormal signal is sent to the cutoff controller 112, the cutoff controller 112 sends a control signal according to the abnormal signal, and FIG. 6B shows that the flow control valve cuts off the fluid distribution according to the control signal.

The aforementioned disc seat valve has two different options for the fluid in and out mode. Referring to Figures 9A and 9B, it is shown that in another embodiment, the flow of fluid in the pan valve is different from that of Figs. 8A and 8B. In Fig. 8A, the fluid of the disc seat valve is the lower left side, and the upper right side is out. In Fig. 9A, the fluid of the disc seat valve is the upper right side and the lower right side. When the microcomputer inductor 111 senses an abnormal state, an abnormal signal is sent to the cutoff controller 112, the cutoff controller 112 sends a control signal according to the abnormal signal, and FIG. 9B shows that the pan seat valve cuts off the fluid distribution according to the control signal. .
