Description

Technical Field

[0001] The utility model relates to the technical field of flow regulation of fog machines, and specifically, to a flow regulation device. Background Art

[0002] There are various ways to adjust the medicine output of existing fog machines (cold fog machines) to meet the needs of different users and application scenarios. The basic adjustment methods include manual adjustment and electric pulse adjustment.

[0003] The manual adjustment method depends on the experience and judgment of the operator. By adjusting the knob or switch on the fog machine, the flow rate of the medicine pipeline can be directly changed, thereby controlling the size of the medicine output.

[0004] The electric pulse adjustment method is to control the electric pulse adjustment pump to achieve the control of the size of the medicine output of the medicine pipeline.

[0005] However, the accuracy, stability, and repeatability of the manual adjustment method are often limited by the experience and skill level of the operator, and it is not stable and reliable. In the low-flow state of the electric pulse adjustment method, the pulse frequency is often relatively low, resulting in uneven medicine output, which may cause a series of problems in practical applications.

[0006] Therefore, it is an urgent problem to be solved by the utility model to provide a flow regulation device that can ensure the accuracy, stability, and repeatability of flow regulation during use and can overcome the problems such as uneven medicine output in the low-flow state of electric pulse regulation. Summary of the Utility Model

[0007] Aiming at the above technical problems, the purpose of the utility model is to overcome the problems of the existing manual adjustment method that depends on the experience and judgment of the operator. By adjusting the knob or switch on the fog machine, the flow rate of the medicine pipeline can be directly changed, thereby controlling the size of the medicine output, and a series of problems of the electric pulse adjustment method that in the low-flow state, the pulse frequency is often relatively low, resulting in uneven medicine output. Thus, a flow regulation device that can ensure the accuracy, stability, and repeatability of flow regulation during use and can overcome the problems such as uneven medicine output in the low-flow state of electric pulse regulation is provided.

[0008] To achieve the above purpose, the utility model provides a flow regulation device, which includes: a diaphragm pump, a pulse regulator, and a mechanical valve; a liquid medicine conduit is connected to the liquid outlet end of the diaphragm pump, a mechanical valve for controlling its flow rate is arranged on the liquid medicine conduit, the diaphragm pump is electrically connected to the pulse regulator, and the pulse regulator is used to adjust the rotation speed of the diaphragm pump by adjusting the width of the pulse signal, thereby controlling the flow rate of the liquid medicine.

[0009] Preferably, the pulse regulator includes: a regulator main body, on which an adjustment knob and a control switch are further provided. The adjustment knob is used to adjust the width of the pulse signal input from the regulator main body to the diaphragm pump, and the control switch is used to control the opening or closing of the regulator main body.

[0010] Preferably, the regulator main body is detachably arranged on the side of the fog machine main body.

[0011] Preferably, an avoidance channel adapted to the liquid medicine conduit is provided on the fog machine main body, and the liquid medicine conduit passes through the avoidance channel.

[0012] Preferably, one end of the liquid medicine conduit is communicated with the liquid outlet end of the electric control regulating pump, and the opposite end thereof is communicated with the nozzle on the fog machine main body.

[0013] According to the above technical solution, the beneficial effects obtained when the flow regulating device provided by the present utility model is in use are as follows: the width of the pulse signal is adjusted by using the pulse regulator to adjust the rotation speed of the diaphragm pump, thereby controlling the flow rate of the liquid medicine. In addition, it can also be adjusted in cooperation with a mechanical valve. For example, in the case of a need for a smaller flow rate, since the pulse frequency often appears to be low, resulting in uneven medicine output and unstable flow rate, at this time, the mechanical valve can be adjusted to reduce the flow rate that can pass through the liquid medicine conduit. Cooperating with the diaphragm pump at a low pulse frequency can significantly enhance the stability of the fog machine. The optimization of the mechanical valve makes the spraying more stable and reduces the risk of shutdown caused by mechanical or electronic failures; ensuring the stability and consistency of the spraying effect.

[0025] The following will describe in detail the specific implementation manner of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manner described herein is only for the purpose of illustrating and explaining the present utility model, and is not used to limit the present utility model.

[0026] In the present utility model, unless otherwise specified, the orientation terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0027] As Figures 1 - 3 shown, the present utility model provides a flow regulating device, and the flow regulating device includes: a diaphragm pump 4, a pulse regulator 2 and a mechanical valve 3; a liquid medicine conduit 1 is connected and arranged at the liquid outlet end of the diaphragm pump 4, a mechanical valve 3 for controlling the flow rate thereof is arranged on the liquid medicine conduit 1, the diaphragm pump 4 is electrically connected to a pulse regulator 2, and the pulse regulator 2 is used to adjust the rotation speed of the diaphragm pump 4 by adjusting the width of the pulse signal, so as to control the flow rate of the liquid medicine.

[0028] In the above solution, the width of the pulse signal is adjusted by the pulse regulator 2 to adjust the rotation speed of the diaphragm pump 4, so as to control the flow rate of the liquid medicine. In addition, it can also be adjusted in cooperation with a mechanical valve. For example, in the case of a need for a smaller flow rate, since the pulse frequency often appears to be lower, resulting in problems such as uneven medicine output and unstable flow rate, at this time, the mechanical valve can be adjusted to reduce the allowable flow rate of the liquid medicine conduit. In cooperation with the diaphragm pump at a low pulse frequency, the stability of the mist machine can be significantly enhanced. The optimization of the mechanical valve makes the spraying more stable and reduces the risk of shutdown caused by mechanical or electronic failures; ensuring the stability and consistency of the spraying effect.

[0029] Moreover, when the device is not in use, the mechanical valve 3 can be directly closed to prevent liquid leakage in the fog machine during long-term non-use or storage. In traditional fog machines, liquid leakage occurs at the connection between the diaphragm pump and the liquid medicine conduit during long-term non-use.

[0030] In a preferred embodiment of the present utility model, the pulse regulator includes: a regulator main body 201, on which an adjustment knob 202 and a control switch 203 are further provided. The adjustment knob 202 is used to adjust the pulse magnitude input from the regulator main body 201 to the diaphragm pump 4, and the control switch 203 is used to control the opening or closing of the regulator main body 201.

[0031] In the above solution, the pulse regulator is electrically connected to the diaphragm pump 4 through a wire 6. The adjustment knob 202 is used for the user to control the width of the pulse signal sent by the pulse regulator to the diaphragm pump 4, thereby adjusting the rotation speed of the diaphragm pump 4 to achieve the adjustment of the liquid medicine flow rate. When not in use, the pulse regulator 2 can be directly turned off through the control switch 203.

[0032] For the regulator main body 201, a PWM regulator can be used to accurately control the width of the pulse signal input to the diaphragm pump 4.

[0033] In a preferred embodiment of the present utility model, the regulator main body 201 is detachably arranged on the side of the fog machine main body 5.

[0034] In the above solution, when the user holds the fog machine main body 5 for use, the control knob on the regulator main body 201 can be directly operated from its side to achieve the purpose of controlling the spraying flow rate.

[0035] In a preferred embodiment of the present utility model, an avoidance channel 204 adapted to the liquid medicine conduit 1 is provided on the fog machine main body 5, and the liquid medicine conduit 1 passes through this avoidance channel 204.

[0036] In the above solution, the structure in which the liquid medicine conduit 1 passes through the avoidance channel 204 can ensure the tightness of the device for convenient user operation. Moreover, the avoidance channel 204 can also limit the liquid medicine conduit 1 to prevent large deviation of the liquid medicine conduit 1.

[0037] In a preferred embodiment of the present utility model, one end of the liquid medicine conduit 1 is connected to the liquid outlet end of the electric control regulating pump 4, and the opposite end is connected to the nozzle on the fog machine main body 5.

[0038] In the above solution, the liquid medicine conduit 1 pumps the liquid medicine into the nozzle and mixes it with the high-temperature steam to be sprayed in an atomized form.

[0039] In summary, when the flow regulating device provided by the present utility model is in use, it overcomes the problems in the prior art where the manual regulation method relies on the experience and judgment of the operator. By adjusting the knob or switch on the fog machine, the flow rate of the chemical agent pipeline can be directly changed, thereby controlling the amount of chemical agent output. It also overcomes a series of problems with the electric pulse regulation method, where in the low flow rate state, the pulse frequency is often relatively low, resulting in uneven chemical agent output.

[0040] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solution of the present utility model, and these simple modifications all fall within the protection scope of the present utility model.

[0041] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.

[0042] Furthermore, any combination can be made among various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should equally be regarded as the content disclosed by the present utility model.
