[0002] Mosquito repelling is a work that needs to be performed frequently in daily life. Common mosquito repelling measures include using mosquito incense and spraying mosquito killing liquid. The mosquito killing liquid is usually concentrated pharmaceutical liquid for storage. When the mosquito killing liquid is sprayed, it needs to be diluted with water to maximize the mosquito killing effect.

The diluted mosquito killing liquid is sprayed to a target position through the output assembly.

[0004] However, the output assembly cannot completely spray the mosquito killing liquid in the pipeline out. If the residual mosquito killing liquid is not used for a long time, the residual mosquito killing liquid will deposit in the pipeline to block the nozzle. In addition, when the temperature is low in winter, the mosquito killing liquid in the pipeline and the output assembly will solidify and expand to cause damage to the pipeline and the output assembly.

[0040] Reference is made to the drawings Figure 1 With the drawings Figure 2 , Figure 1 is a perspective view of the mosquito killing device of the present application; Figure 2 is a front view of the mosquito killing device of the present application; the following will be described in combination with the drawings Figure 1 With the drawings Figure 2 The specific embodiments will be described.

[0041] Reference is made to the drawings Figure 1The application provides a mosquito killing device, which comprises a shell 100, a water inlet assembly 200, a medicine inlet assembly 300, an output assembly 400, an emptying assembly 500 and a control assembly 600. The shell 100 is provided with a water outlet, and the water inlet assembly 200 and the medicine inlet assembly 300 are arranged in the shell 100. The output assembly 400 is arranged in the shell 100 and is communicated with the water inlet assembly 200, the medicine inlet assembly 300 and the water outlet through a plurality of pipelines. The output assembly 400 is used for mixing the solution flowing in from the water inlet assembly 200 and the medicine inlet assembly 300 and spraying out through the water outlet. The emptying assembly 500 is arranged in the shell 100 and is communicated with the pipeline between the water inlet assembly 200 and the output assembly 400 and / or the pipeline between the medicine inlet assembly 300 and the output assembly 400. The control assembly 600 is electrically connected with the water inlet assembly 200, the medicine inlet assembly 300, the emptying assembly 500 and the output assembly 400.

[0042] In some embodiments, the shell 100 is provided with a water outlet. The emptying assembly 500 comprises an emptying pump 501 and an emptying pump one-way valve 502. The emptying pump 501 is communicated with the pipeline between the water inlet assembly 200 and the output assembly 400 and / or the pipeline between the medicine inlet assembly 300 and the output assembly 400. The emptying pump one-way valve 502 is arranged at the output end of the emptying pump 501.

[0043] Specifically, the shell 100 is a solid and durable hollow container used for accommodating the water inlet assembly 200, the medicine inlet assembly 300, the output assembly 400 and the emptying assembly 500. The shell 100 is made of plastic, metal or any other suitable material to ensure that it can withstand internal pressure and prevent chemical leakage. The shape and size of the shell 100 are customized according to actual application requirements to adapt to different use environments and carrying methods.

[0044] The emptying assembly 500 comprises an emptying pump 501 and an emptying pump one-way valve 502. The emptying pump 501 comprises a small electric pump or an air pump, which can generate sufficient pressure to push the liquid in the pipeline. The emptying pump 501 is communicated with the pipeline between the water inlet assembly 200 and the output assembly 400 and / or the pipeline between the medicine inlet assembly 300 and the output assembly 400, so that the target of emptying is the output assembly 400 and the pipeline between the output assembly 400 and the water outlet. Optionally, the emptying pump 501 is provided with a control valve to start or stop the emptying process when needed.

[0045] The emptying pump check valve 502 is a valve installed at the output end of the emptying pump 501, which only allows one-way flow of liquid; this means that liquid can flow from the emptying pump 501 to the output assembly 400, but not in the reverse direction. This design can prevent the solution from flowing back to the water inlet assembly 200 or the medicine inlet assembly 300 during the emptying process, thereby ensuring the efficiency of the emptying process and the safe operation of the equipment.

[0046] In practical applications, the control assembly 600 will control the operation of the emptying pump 501 according to the preset program or user instructions. For example, when it is detected that the concentration of the solution in the pipeline is lower than the predetermined value, the control assembly 600 will start the emptying pump 501 to empty the pipeline in order to re-inject new solution; similarly, when the equipment needs to be maintained or the solution needs to be replaced, the control assembly 600 will also start the emptying pump 501 to empty the residual solution in the pipeline.

[0047] Referring to the accompanying drawings Figure 1 With Figure 2 In some embodiments, the water inlet assembly 200 is used to supply water from a water storage tank to the output assembly 400, and the water inlet assembly 200 includes an electromagnetic ball valve 201, a flow meter 202, and a water inlet check valve 204 arranged in sequence from the water storage tank to the output assembly 400, and the emptying pump check valve 502 is connected to the pipeline between the flow meter 202 and the water inlet check valve 204.

[0048] Specifically, the water inlet assembly 200 is used to draw water from a water storage tank or other water source and deliver it to the output assembly 400, and the water inlet assembly 200 includes an electromagnetic ball valve 201, a flow meter 202, and a water inlet check valve 204.

[0049] The electromagnetic ball valve 201 is a valve that can be controlled to open and close by an electromagnetic coil, and the electromagnetic ball valve 201 is installed on the pipeline between the water storage tank and the output assembly 400; when the electromagnetic coil is energized, the valve opens to allow water to flow through; when the electromagnetic coil is de-energized, the valve closes to prevent water flow. This allows the control assembly 600 to accurately control the flow of water through electrical signals, thereby achieving automated operation.

[0050] The flow meter 202 is a device for measuring water flow rate and flow, and the flow meter 202 is installed between the electromagnetic ball valve 201 and the water inlet check valve 204 to monitor and control the amount of water entering the output assembly 400. The flow meter 202 communicates the amount of water entering to the control assembly 600, which controls the frequency of the plunger pump 301 to control the amount of medicine, so that the nozzle liquid concentration reaches a certain proportion; the flow meter 202 includes a turbine flow meter 202, an ultrasonic flow meter 202, or an electromagnetic flow meter 202 to ensure accurate measurement. The data from the flow meter 202 is fed back to the control assembly 600 for real-time adjustment and optimization of water supply.

[0051] The water inlet check valve 204 is a valve that allows water to flow in only one direction. The water inlet check valve 204 is installed at the output end of the flow meter 202 to ensure that water can only flow from the water storage tank to the output assembly 400, thereby preventing backflow of the solution in the system when water supply to the output assembly 400 is stopped.

[0052] The emptying pump check valve 502 is arranged on the pipeline between the flow meter 202 and the water inlet check valve 204. When it is necessary to empty the pipeline, the emptying pump 501 generates air pressure to force the gas to flow to the output assembly 400 through the emptying pump check valve 502. Due to the design of the water inlet check valve 204, liquid cannot flow back to the flow meter 202 and the electromagnetic ball valve 201 in the opposite direction, thereby ensuring the effectiveness of the emptying process.

[0053] Referring to the accompanying drawings Figure 2 In some embodiments, the water inlet assembly 200 further comprises a filter 203 arranged between the flow meter 202 and the water inlet check valve 204, and the emptying pump check valve 502 communicates the pipeline between the flow meter 202 and the filter 203.

[0054] Specifically, the filter 203 is used to remove impurities and particulate matter in water to ensure that the water entering the output assembly 400 is clean, thereby improving the efficiency and service life of the entire mosquito killing device. The filter 203 includes a Y-type filter, a mesh filter, an activated carbon filter, and a microporous filter; the selection of the filter 203 depends on the required filtering accuracy and the specific requirements of the system; the emptying pump check valve 502 communicates the pipeline between the flow meter 202 and the filter 203, so that the water input to the output assembly 400 by air pressure is water that has removed impurities after passing through the filter 203; optionally, the filter 203 is a Y-type filter with a filtering accuracy of 40um to filter impurities in water.

[0055] Referring to the accompanying drawings Figure 2 In some embodiments, the water inlet assembly 200 is used to deliver a liquid medicine from a liquid medicine tank to the output assembly 400, and the liquid medicine inlet assembly 300 comprises a plunger pump 301 and a plunger pump check valve 302 arranged in sequence from the liquid medicine tank to the output assembly 400, and the emptying pump check valve 502 communicates the pipeline between the plunger pump check valve 302 and the output assembly 400.

[0056] Specifically, the plunger pump 301 is made of various materials and sizes to adapt to different liquid medicines and flow requirements. For example, for thick concentrated mosquito killing liquid medicine, a larger plunger diameter and a stronger driving mechanism are required to overcome high viscosity; the plunger pump 301 generally includes a sealed cylinder body with a reciprocating plunger inside, as well as inlet and outlet valves to control the inflow and outflow of the liquid medicine.

[0057] The plunger pump check valve 302 is a check valve that only allows the drug solution to flow from the plunger pump 301 to the output assembly 400, preventing backflow when the pump is stopped. The plunger pump check valve 302 is spring-loaded or relies on the pressure of the drug solution to remain closed until the pump generates enough pressure to open the valve.

[0058] The frequency of movement of the plunger pump 301 (i.e., the reciprocating speed of the plunger) is controlled by the control assembly 600 based on the signals from the flow meter 202, thereby precisely regulating the amount of drug solution to ensure that the concentration of the drug solution output by the output assembly 400 reaches the required level.

[0059] To prevent the thick mosquito repellent solution from clogging the pipeline, the control assembly 600 will separately turn off the plunger pump 301 after the spraying operation is completed, and open the electromagnetic ball valve 201 through the control assembly 600 to fill the pipeline with water, which can flush away the residual drug solution and prevent the pipeline from being clogged.

[0060] When it is necessary to empty the pipeline, the emptying pump 501 generates air pressure to push the drug solution or water in the pipeline out of the water outlet through the output assembly 400, thereby achieving the emptying of the pipeline. Through the cooperation of the water inlet assembly 200 and the drug inlet assembly 300, the drug inlet assembly 300 can effectively transport the drug solution from the drug solution tank to the output assembly 400, and the flow rate of the drug solution can be adjusted by precisely controlling the frequency of movement of the plunger pump 301, ensuring that the concentration of the drug solution at the nozzle meets the requirements.

[0061] In some embodiments, the drug inlet assembly 300 also includes a liquid level sensor installed in the pipeline between the plunger pump 301 and the plunger pump check valve 302 and electrically connected to the control assembly 600.

[0062] Specifically, the liquid level sensor is a device used to monitor the change in the liquid level in the drug solution tank to provide real-time information about the liquid level of the drug solution to the control assembly 600. The liquid level sensor includes a float type, a capacitive type, an ultrasonic type, and a radar type. In the drug solution delivery system, a liquid level sensor made of a material resistant to chemical corrosion is more preferred to adapt to the chemical properties of the drug solution.

[0063] The liquid level sensor is usually installed on the drug solution tank or on the pipeline between the plunger pump 301 and the plunger pump check valve 302. This ensures that the sensor can accurately detect the liquid level of the drug solution and send a signal to the control assembly 600 when the liquid level of the drug solution is too low.

[0064] The liquid level sensor is connected to the control assembly 600 through a cable or wireless communication. The sensor converts the detected liquid level information into an electrical signal and transmits it to the control assembly 600. The control assembly 600 can monitor the liquid level of the drug solution tank in real time based on these signals and issue an alarm when the liquid level is below the set value.

[0065] The control assembly 600 can adjust the working state of the plunger pump 301 according to the signal of the liquid level sensor. For example, when the liquid level is too low, the control assembly 600 can reduce the movement frequency of the plunger pump 301 to avoid idling of the pump; when the liquid level returns to normal, the control assembly 600 can restore the normal working frequency of the plunger pump 301.

[0066] The liquid level sensor is used for safety protection of the system to prevent the plunger pump 301 from continuing to work in the no-liquid state, thereby protecting the pump from damage; in addition, by monitoring the liquid level, the system can also automatically record the consumption of the liquid medicine, helping the user to plan the replenishment and maintenance of the liquid medicine.

[0067] Reference is made to the accompanying drawings Figure 2 In some embodiments, the output assembly 400 includes a booster pump 401 and a pressure reducing valve 402, the booster pump 401 is in communication with the water inlet assembly 200, the liquid medicine inlet assembly 300 and the water outlet, and the pressure reducing valve 402 is arranged between the booster pump 401 and the water outlet.

[0068] Specifically, the booster pump 401 includes a centrifugal pump, a gear pump or a diaphragm pump, which should be selected according to the viscosity, corrosiveness and required flow rate and pressure of the liquid medicine; the booster pump 401 is in communication with the water inlet assembly 200, the liquid medicine inlet assembly 300 and the water outlet, that is, the input end of the booster pump 401 receives water from the water inlet assembly 200 and liquid medicine from the liquid medicine inlet assembly 300, and the output end of the booster pump 401 is connected to the water outlet for outputting the mixed solution; the booster pump 401 is controlled by the control assembly 600, and the speed or flow rate thereof can be adjusted to adapt to different working requirements; the booster pump 401 is driven by a booster motor, which includes a stepper motor and a servo motor.

[0069] The pressure reducing valve 402 is used for stabilizing the output pressure to prevent damage to the system or the user caused by excessively high output pressure; the pressure reducing valve 402 is arranged between the booster pump 401 and the water outlet to adjust the pressure before the solution is outputted; the pressure reducing valve 402 has an adjustable setting, and the operator can adjust the opening of the pressure reducing valve 402 according to requirements to control the range of the output pressure; the pressure reducing valve 402 also plays a role in safety protection, and when the emptying assembly 500 works to increase the pressure, the pressure reducing valve 402 can be automatically opened to release the excess pressure, thereby protecting the booster pump 401 and the pipeline from damage. In actual application, the combination of the booster pump 401 and the pressure reducing valve 402 can ensure that the mixed solution of the liquid medicine and water can be outputted at a constant pressure, which is particularly important for some application scenarios that require precise control of the pressure of the mosquito-killing liquid to enable the spray to be sprayed to a predetermined position to achieve a good effect of killing mosquitoes.

[0070] Reference is made to the accompanying drawings Figure 1 With Figure 2In some embodiments, the mosquito killing device further comprises a liquid leakage sensor 700, which is arranged in the housing 100 and electrically connected with the control assembly 600.

[0071] Specifically, the liquid leakage sensor 700 is used to improve the safety and reliability of the mosquito killing device when unattended, preventing damage to the device or environmental pollution caused by liquid leakage; the liquid leakage sensor 700 includes a float switch, a capacitive sensor or an optical sensor, and the operator should consider its sensitivity, anti-interference ability and compatibility with the liquid when selecting the liquid leakage sensor 700.

[0072] The liquid leakage sensor 700 is usually installed at key positions where the liquid is stored or flows, such as the bottom of the liquid tank, near the liquid pipeline or around the nozzle, so as to detect any possible leakage in time.

[0073] The main function of the liquid leakage sensor 700 is to send a signal to the control assembly 600 immediately when liquid leakage is detected. After receiving the signal, the control assembly 600 can take corresponding measures, such as turning off the liquid pump, issuing an alarm or recording the leakage event.

[0074] The liquid leakage sensor 700 needs to be electrically connected with the control assembly 600, which is usually achieved through wires or wireless communication modules, and the specific connection method depends on the overall design of the device and the user's demand for flexibility; in addition to sending a signal to the control assembly 600 when the liquid leakage sensor 700 detects leakage, it can also directly trigger an audible and visual alarm or other forms of warning to remind the operator to take immediate action; the liquid leakage sensor 700 also plays a safety protection role, preventing electrical short circuits or other safety problems that may be caused by liquid leakage.

[0075] Reference is made to the accompanying drawings Figure 1 With Figure 2 In some embodiments, the control assembly 600 includes a power supply, a control board, a driver and a DTU wireless communication module, and the power supply is electrically connected with the control board, the driver and the DTU wireless communication module respectively.

[0076] Specifically, the power supply includes an AC power adapter, a DC power supply or a solar panel, and the operator should select the appropriate type of power supply according to the power demand of the device and the use environment; the power supply is used to provide stable voltage and current output to ensure the normal work of the control board, the driver and the DTU wireless communication module; optionally, the power supply has overload protection, short circuit protection and voltage fluctuation protection functions to improve the safety of the entire system.

[0077] The core of the control board is a microprocessor responsible for handling all logical control and data processing tasks. The control board is equipped with sufficient memory for storing program code, device parameters, and running data. The control board is also equipped with multiple input / output interfaces for connecting various sensors, actuators, and communication modules. Optionally, the control board is built-in with a real-time clock (RTC) to ensure accurate timekeeping even without external time synchronization.

[0078] The driver includes a relay driver, a motor driver, or a solid-state relay. The operator should select the appropriate driver based on the type of load to be driven. The driver receives signals from the control board and converts them into corresponding voltages and currents to drive the water inlet assembly 200, the pesticide inlet assembly 300, the emptying assembly 500, and the output assembly 400 in the mosquito-killing device. Optionally, the driver has overheat protection and overcurrent protection to prevent damage caused by abnormal loads.

[0079] The DTU module is used to upload device running data to the server and receive instructions from the server, such as timing tasks or parameter adjustments. The DTU wireless communication module supports multiple wireless communication protocols, such as GSM / GPRS, CDMA, PHS, LTE, or NB-IoT. The operator should select the appropriate protocol based on network coverage and data transmission requirements. Optionally, the DTU wireless communication module is connected to an antenna to ensure stable signal transmission.

[0080] In some embodiments, the mosquito-killing device also includes a water outlet pipe, one end of which is in communication with the water outlet, and one or more output ports are provided on the water outlet pipe. That is, the water outlet pipe is in communication with the output end of the output assembly 400, and the mixed and pressurized mosquito-killing pesticide solution is sprayed through the output ports of the water outlet pipe to a designated location or multiple predetermined locations for mosquito-killing and pest control. Optionally, one or more atomizing nozzles are provided at the output ports to uniformly spray the pesticide.

[0081] The application provides a mosquito killing device, which evacuates the mosquito killing liquid in the pipeline and the output assembly 400 through the evacuation assembly 500, avoids the expansion of the mosquito killing liquid after deposition or solidification, fills the air into the pipeline through the cooperation of the evacuation pump 501 and the evacuation pump one-way valve 502, evacuates the residual liquid in the output assembly 400 and the pipeline by using the air pressure, quantitatively supplies water to the output assembly 400 through the cooperation of the electromagnetic ball valve 201 and the flow meter 202, accurately controls the dilution ratio, supplies the concentrated liquid to the output assembly 400 through the plunger pump 301, filters the impurities in the water through the filter 203, sends the diluted liquid to the atomizing nozzle through the booster pump 401 and the pressure reducing valve 402, releases the liquid in the form of spray, monitors the amount of the concentrated liquid in the pipeline through the liquid level sensor, supplements the concentrated liquid in time, monitors whether there is liquid at the bottom of the shell 100 through the liquid leakage sensor 700, and issues an alarm when there is liquid leakage.
