Description

Technical Field

[0001] The utility model relates to the technical field of fog machines, and specifically, to a multifunctional impeller pump. Background Art

[0002] The liquid medicine delivery pump bodies of existing cold fog machines (fog machines) generally adopt diaphragm pumps and electromagnetic pumps, which bring great drawbacks in pumping pesticides.

[0003] Firstly, the chemical properties of pesticides themselves are complex. Some are highly corrosive, while others are prone to precipitation or crystallization. When the diaphragm pump pumps these pesticides for a long time, the internal diaphragm and seals are easily eroded by the pesticides, resulting in performance degradation or even failure. This not only increases the frequency of maintenance and component replacement but also raises the agricultural production cost.

[0004] Secondly, impurities and particulate matters in pesticides may also damage the diaphragm pump. During the pumping process, these impurities and particulate matters may block the inlet and outlet of the pump, affecting the working efficiency of the pump; at the same time, they may also scratch the diaphragm and seals, further exacerbating the wear of the pump.

[0005] Therefore, it is an urgent problem to be solved by the utility model to provide a multifunctional impeller pump that can overcome the above technical problems during use, ensure the uniformity and stability of pesticides, and ensure smoother flow of pesticides in the pump body, reducing the problem of reduced suction efficiency caused by blockage or excessive resistance. Summary of the Utility Model

[0006] Aiming at the above technical problems, the purpose of the utility model is to overcome the problems that the liquid medicine delivery pump bodies of fog machines in the prior art generally adopt diaphragm pumps and electromagnetic pumps. During use, the internal diaphragm and seals are easily eroded by pesticides, resulting in performance degradation or even failure; and impurities and particulate matters may block the inlet and outlet of the pump, affecting the working efficiency of the pump; at the same time, they may also scratch the diaphragm and seals, further exacerbating the wear of the pump. Thus, a multifunctional impeller pump is provided that can overcome the above technical problems during use, ensure the uniformity and stability of pesticides, and ensure smoother flow of pesticides in the pump body, reducing the problem of reduced suction efficiency caused by blockage or excessive resistance.

[0007] To achieve the above purpose, the utility model provides a multifunctional impeller pump, which includes: a motor, stirring blades, and a suction mechanism; at least a part of the top of the output shaft of the motor extends into the interior of the suction mechanism to drive the internal rotation to generate negative pressure to suck the liquid medicine, and discharge it through the liquid outlet pipe, and the stirring blades are fixedly sleeved in the middle of the output shaft of the motor.

[0008] Preferably, the suction mechanism includes: a base, an impeller rotatably disposed on the upper surface of the base, and a housing detachably disposed on the base to cover the impeller; the top of the output shaft of the motor is fixedly connected to the center of the impeller, and an opening is provided at the top of the housing.

[0009] Preferably, the suction mechanism further includes: a filter screen plate, which is detachably disposed on the top of the housing to cover its opening.

[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 used to illustrate and explain the present utility model, and is not used to limit the present utility model.

[0026] In the present utility model, unless otherwise stated, 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 of the terms.

[0027] As Figures 1-3 shown, the present utility model provides a multi-functional impeller pump, and the multi-functional impeller pump includes: a motor 1, a stirring blade 4, and a suction mechanism 2; at least a part of the top of the output shaft of the motor 1 extends into the inside of the suction mechanism 2 to drive the internal rotation to generate negative pressure to suck the liquid medicine, and discharge it through the liquid outlet pipe 3, and the stirring blade 4 is fixedly sleeved on the middle part of the output shaft of the motor 1.

[0028] In the above solution, when the multi-functional impeller pump is in use, the whole impeller pump is placed in the medicine barrel for assembly, and then the power is connected to start the work. During the work process, the suction mechanism 2 rotates under the driving action of the motor 1 to generate a negative pressure environment, so as to suck the liquid medicine into its inside and then discharge it from the liquid outlet pipe 3. A stirring blade 4 is also arranged in the middle part of the output shaft of the motor 1 and rotates accordingly during the work, so as to stir the liquid medicine in the liquid barrel, so as to ensure that the liquid medicine is fully stirred before entering the suction mechanism 2, so as to ensure its uniform mixing, avoid precipitation and stratification phenomena, and ensure the effective use of pesticides.

[0029] In a preferred embodiment of the present utility model, the suction mechanism 2 includes: a base 201, an impeller 202 rotatably arranged on the upper surface of the base 201, and a housing 203 detachably arranged on the base 201 to cover the impeller 202; the top of the output shaft of the motor 1 is fixedly connected to the center of the impeller 202, and the top of the housing 203 is provided with an open mouth.

[0030] In the above solution, the impeller 202 rotates driven by the motor. On the one hand, it can further stir the liquid medicine to ensure the uniformity of mixing. During a long-term suction process, some components in the pesticide may form sediments in the pump body due to precipitation or crystallization. However, the impeller can continuously stir the liquid in the pump body through its continuous rotation, thereby preventing the formation of these sediments and ensuring the uniformity and stability of the pesticide. On the other hand, its rotation generates a negative pressure environment, thereby sucking the liquid medicine in the medicine barrel into the interior and then driving it to be discharged through the liquid outlet pipe.

[0031] It should also be noted that the materials of the stirring blade 4 and the impeller 202 are both corrosion-resistant plastics or metals. Because pesticides often contain some components that are corrosive to metals, and the stirring impeller and the pump body are made of corrosion-resistant materials, they can resist these corrosions and ensure the long-term stable operation of the pump. At the same time, the impeller is treated by a special process and has high wear resistance, and can maintain good performance even under long-term and high-intensity operation. This material can be stainless steel or polytetrafluoroethylene PTFE material, and its specific performance will not be elaborated here.

[0032] In a preferred embodiment of the present utility model, the suction mechanism 2 further includes: a filter screen plate 204, and the filter screen plate 204 is detachably arranged on the top of the housing 203 to cover its open mouth.

[0033] In the above solution, the filter screen plate 204 can filter the liquid medicine entering the suction mechanism 2 to prevent foreign objects from entering the pump body and causing blockage problems, and the mesh structure of the filter screen plate 204 can also conduct the liquid medicine, further improving its stirring and mixing effect.

[0034] In a preferred embodiment of the present utility model, a support seat 5 is fixedly arranged at the end of the motor 1 on one side of the output shaft, the output shaft of the motor 1 penetrates through the middle of the support seat 5, and the suction mechanism 2 is detachably arranged on the top of the support seat 5.

[0035] In the above solution, the support seat 5 plays a supporting role to ensure the overall stability of the suction mechanism 2.

[0036] In a preferred embodiment of the present utility model, the middle part of the support base 5 is recessed downward so that the whole is in an inverted "C" shape, and the stirring blade 4 is located in the middle of the recess of the support base 5.

[0037] In the above solution, the stirring blade 4 is located at the bottom of the suction mechanism 2. On the one hand, it ensures that the liquid medicine entering the inside of the suction mechanism 2 undergoes a stirring and mixing operation. Moreover, this structure also makes the overall structure of the impeller pump more compact, preventing the volume from being too large and affecting the occupied space.

[0038] In a preferred embodiment of the present utility model, the motor 1 is a waterproof motor. Since the motor 1 is immersed in the medicine barrel for use, the waterproof performance is also necessary to ensure its normal operation.

[0039] In summary, when the multifunctional impeller pump provided by the present utility model is in use, it ensures the uniformity and stability of the pesticide, and also ensures that the flow of the pesticide in the pump body is smoother, reducing the problem of the decrease in the suction efficiency caused by blockage or excessive resistance. When in use, the flow rate can be controlled by adjusting the rotation speed of the motor.

[0040] The preferred embodiments of the present utility model have been described in detail above with reference to 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 solutions of the present utility model, and these simple modifications all belong to the protection scope of the present utility model.

[0041] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described 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] In addition, any combination can be made between 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 also be regarded as the content disclosed by the present utility model.
