Description

[Technical field]

[0001] The present invention belongs to the technical field of mosquito-killing electrified screen doors, and relates to an intelligent voltage-adjustable electrified screen door. [Background technology]

[0002] Windows, one of the main routes through which mosquitoes fly between indoors and outdoors, can be electrically charged to effectively kill mosquitoes.

[0003] In the process of killing mosquitoes using a conventional electrostatic screen, a high voltage needs to be applied to the electrostatic screen, and the working voltage of the net of the electrostatic mosquito swatter reaches 2000V-4200V according to the industry standard "QB / T 4496-2013 electrostatic mosquito swatter", so the working voltage of the electrostatic screen has also been set to 2000V-4200V. However, when killing mosquitoes under high voltage conditions of 2000V-4200V, not only will the mosquito corpses pop and stick to the electrostatic screen, making them difficult to remove, but also will leave burn marks on the metal net thread of the electrostatic screen, making the electrostatic screen cloudy, worsening the visibility of the electrostatic screen, and shortening the service life of the electrostatic screen. In addition, noise will be generated when killing mosquitoes with an electric shock, and since there are more mosquitoes outdoors, killing so many mosquitoes with an electric shock will frequently generate noise, which will affect people.

[0004] Therefore, it is urgent to propose an intelligent voltage-adjustable charged screen door that can reduce the noise frequency caused by mosquito killing to reduce the impact of the charged screen door on users, and also reduce the number of mosquito corpses that stick to the screen door and the burn marks left on the charged screen door, thereby extending the service life of the charged screen door. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the problems in the background art, the present invention aims to propose an intelligent voltage-adjustable charged screen door based on the following technical means: The voltage of the charged screen door is limited to the range of 120-300V. Within this voltage range, mosquitoes are not killed, but when they touch the charged screen door, they are shocked and fly away from the charged screen door. Therefore, when the voltage of the charged screen door is in the range of 120-300V, it can only have the effect of repelling mosquitoes that try to enter a room through the gaps in the screen door, but since mosquitoes are not killed, it can prevent many mosquito corpses from sticking to the charged screen door, reduce the burn marks on the charged screen door, extend the service life of the charged screen door, and avoid the impact of noise caused by killing a large number of mosquitoes on the user. The voltage of the charged screen door is limited to the range of 900-1950V. Within this voltage range, mosquitoes that come into contact with the electrostatic screen door are killed quickly, many of the mosquito corpses do not break, and the noise caused by killing the mosquitoes is small. Therefore, when the voltage of the electrostatic screen door is in the range of 900-1950, the mosquito corpses do not break and the mosquitoes inside the room are killed, which reduces the number of mosquito corpses that stick to the electrostatic screen door, extends the service life of the electrostatic screen door, and also helps to reduce the impact of the noise caused by killing the mosquitoes on the user. Based on the behavior of mosquitoes, the voltage is limited to the range of 120-300V during the time period when mosquitoes tend to enter the room, and the voltage is limited to the range of 900-1950V during the time period when mosquitoes tend to fly outdoors, so that the electrostatic screen door can achieve a mosquito repellent or mosquito killing effect during the appropriate time period. Usually, mosquitoes need to mate or find a place to lay eggs and search for food during the time period of 5:00-7:30 and 17:00-19:00, so they tend to fly from indoors to outdoors during these times. Moreover, a large amount of experimental observations show that many mosquitoes follow the above-mentioned behaviors. For example, Anopheles and malaria-carrying mosquitoes commonly found in China tend to fly outdoors between 17:00 and 19:00, while house mosquitoes tend to fly outdoors between 5:00 and 7:30.

Effect of the Invention

[0015] The present invention has the following beneficial effects:

[0016] 1.

[0023] Orientation terms such as left and right described herein serve as a convenient descriptive method for describing the structure of the present invention, but the present invention is not limited by orientation terms in practice.

[0024] We will now explain the present invention in more detail in conjunction with specific examples.

[0025] In embodiment 1 of the present invention, as shown in FIG. 1, an intelligent voltage-adjustable electrified screen door comprises a mesh array 1 and a control system 2, the metal threads in the odd rows of the mesh array 1 extend to one side of the mesh array 1 to form a positive electrode connector 3, the metal threads in the even rows of the mesh array 1 extend to the other side of the mesh array 1 to form a negative electrode connector 4, the vertical lines of the mesh array 1 are made of a non-conductive material, the positive electrode of the control system 2 is electrically connected to the positive electrode connector 3, the negative electrode of the control system 2 is electrically connected to the negative electrode connector 4, and the input end of the control system 2 is electrically connected to the output end of a power source.

[0026] As shown in FIG. 8 , the control system 2 includes a time control switch 201, a relay 202, a first boost module 203, and a second boost module 204. The input end of the time control switch 201 is electrically connected to the output end of the power source, the output end of the time control switch 201 is electrically connected to the input end of the relay 202, and the output end of the relay 202 is electrically connected to the first boost module 203 and the second boost module 204 respectively through a branch line. The output terminals of the boost module 203 and the second boost module 204 are electrically connected to the mesh array 1, and the voltage range applied to the mesh array 1 from the first boost module 203 is 120 to 300V, and the voltage range applied to the mesh array 1 from the second boost module 204 is 900 to 1950V, and the voltage applied to the mesh array 1 is limited to the range of 120 to 300V or 900 to 1950V respectively during a time period under the control of the control system 2.

[0027] In this embodiment, the mesh array 1 may be placed inside the original window frame 7 by means of a magnetic strip, attachment, etc. The mesh array 1 may be fixed to the original window frame 7, and the control system 2 may also be fixedly attached to the original window frame 7. If the mesh array 1 is attached inside the original window frame 7, holes are drilled in the window frame 7 to allow the connection wiring between the control system 2 and the mesh array 1 to pass through.

[0028] In this embodiment, an experiment was conducted using an electrically charged screen door with a voltage of 120V. When the electrically charged screen door was placed in an environment containing mosquitoes, it was found through observation that there was no situation in which the mosquito would be killed by the electric shock, nor was there a situation in which the mosquito would pass through mesh arrangement 1, and furthermore, wherever a mosquito landed on the electrically charged screen door, it would immediately fly away from the electrically charged screen door.

[0029] In this experiment, an experiment was conducted using an electrically charged screen with a voltage of 900V. When the electrically charged screen was placed in an environment with mosquitoes, it was discovered through observation that most of the mosquitoes were killed by an electric shock immediately upon touching the electrically charged screen, the bodies of the killed mosquitoes fell to the ground without sticking to the electrically charged screen, there were almost no burn marks on the electrically charged screen, and in addition, the hearing sensitivity of the noise caused by the mosquito killer was relatively low.

[0030] The power supply generally adopts 5VDC power. The voltage of 5V output from the power supply is boosted to a voltage range of 120-300V through the first boost module 203, and the first boost module 203 can directly purchase a product that can reach a suitable boost factor of the voltage according to the application of the present invention. After the voltage is boosted by the first boost module 203, the voltage reaches a range of 120V-300V, and the voltage is transmitted to the mesh array through the circuit. The voltage of 5V output from the power supply is boosted to a voltage range of 900-1950V through the second boost module 204, and the second boost module 204 can directly purchase a product that can reach a suitable boost factor of the voltage according to the application of the present invention. After the voltage is boosted by the second boost module 204, the voltage reaches a range of 900V-1950V, and the voltage is transmitted to the mesh array through the circuit.

[0031] There is a possibility to directly switch between automatic control and manual control by using the time control switch 201. In the automatic control mode, if the user does not set the time period, the time control switch 201 performs control according to the preset time period, and in the time periods of 5:00~7:30 and 17:00~19:00, the second boost module 204 is turned on and the first boost module 203 is turned off under the control of the time control switch 201, so that the voltage on the mesh array 1 is in the range of 900~1950V. In other time periods, the second boost module 204 is turned off and the first boost module 203 is turned on under the control of the time control switch 201, so that the voltage on the mesh array 1 is in the range of 120~300V. When there is a special situation in the behavior of mosquitoes in the area where the user is, the user can newly set the time periods for the second boost module 204 and the first boost module 203 to be turned on and off according to the actual situation. In the manual control mode, the time control switch 201 does not automatically switch the on and off time periods of the second boost module 204 and the first boost module 203, but the user needs to switch them manually.

[0032] After the control system 2 is connected to the power source, the indicator light turns on and the second boost module 204 turns on, and the voltage on the mesh array 1 is in the range of 900-1950V, so that the indicator light of the time control switch 201 can provide the user with the information that the second boost module 204 and the first boost module 203 are turned on and off. The indicator light of the time control switch 201 turns on indicates that the second boost module 204 is turned on and the first boost module 203 is turned off.

[0033] After the control system 2 is connected to the power source, when the indicator light of the time control switch 201 is off and the first boost module 203 is turned on, the boost module whose indicator light is on is the first boost module 203, and at this time, the voltage on the mesh array 1 is in the range of 120-300V. Thus, when the indicator light of the time control switch 201 is off, it means that the second boost module 204 is off and the first boost module 203 is on.

[0034] In the actual use process, each component of the control system 2 and the human body sensitive power cutoff device 10 may be mounted on the housing, and only the display screen, keys and indicator lights of the time control switch 201 and the probe of the human body sensitive power cutoff device 10 need to be exposed, which does not affect the actual use of the control system 2. Comparative Example 1

[0035] In this experiment, a commercially available electrostatic screen door with a voltage of 2000V was used. When the electrostatic screen door was placed in an environment with mosquitoes, it was observed that all mosquitoes that touched the electrostatic screen door were killed by an electric shock. Compared to Example 1, more mosquito corpses were found to have attached themselves to the electrostatic screen door, electric burn marks appeared in several places on the electrostatic screen door, and the hearing sensitivity of the noise caused by the mosquito killer was relatively high. Comparative Example 2

[0036] In this experiment, a commercially available electrostatic screen door with a voltage of 110V was used, and it was found that when the electrostatic screen door was placed in an environment where there were mosquitoes, the time that mosquitoes stayed on the electrostatic screen door increased, and in addition, the phenomenon of mosquitoes passing through the mesh of the electrostatic screen door occurred, and the effect of using the electrostatic screen door to repel mosquitoes was reduced.

[0037] In this experiment, a commercially available charged screen door with a voltage of 800V was used. When the charged screen door was placed in an environment where there were mosquitoes, it was observed that some of the mosquitoes were struck by electricity and fainted, but were not killed, and it was discovered that the mosquito-killing effect of the charged screen door was significantly reduced compared to Example 1.

[0038] In the second embodiment of the present invention, as shown in FIG. 2-3, the intelligent voltage-adjustable electrostatic screen includes a positive conductive member 5 and a negative conductive member 6, and the positive conductive member 5 and the negative conductive member 6 are both provided with clasps. When the positive electrode connector 3 is fastened to the clasp of the positive conductive member 5, the positive electrode of the control system 2 is electrically connected to the positive conductive member 5, and when the negative electrode connector 4 is fastened to the clasp of the negative conductive member 6, the negative electrode of the control system 2 is electrically connected to the negative conductive member 6. The positive electrode of the control system 2 and the positive conductive member 5, and the negative electrode of the control system 2 and the negative conductive member 6 are both connected by only one electric wire, so that the electrostatic screen can be supplied with power. As a result, the electrostatic screen generates a voltage and does not require a branch line, which reduces the number of electric wires and reduces the intensity of manual wiring work, and avoids the problem of tangled electric wires causing a messy visual effect.

[0039] In this embodiment, the mesh array 1 may be placed inside the original window frame 7 by means of a magnetic strip, attachment, etc. The mesh array 1 may be fixed to the original window frame 7, and the control system 2 may also be fixedly attached to the original window frame 7. If the mesh array 1 is attached inside the original window frame 7, holes are drilled in the window frame 7 to allow the connection wiring between the control system 2 and the mesh array 1 to pass through.

[0040] In this embodiment, an experiment was conducted using an electrically charged screen door with a voltage of 300V. When the electrically charged screen door was placed in an environment containing mosquitoes, it was discovered through observation that there was no situation in which the mosquitoes would be killed by the electric shock, and there was also no situation in which the mosquitoes would pass through mesh arrangement 1, and in fact the mosquitoes hardly ever touched the electrically charged screen door.

[0041] In this embodiment, an experiment was conducted using an electrically charged screen door with a voltage of 1950V. When the electrically charged screen door was placed in an environment where there were mosquitoes, it was observed that the mosquitoes were immediately killed by an electric shock where they touched the electrically charged screen door, and some mosquitoes survived the electric shock. It was discovered that compared to Example 1, the number of mosquito corpses that were killed and stuck to the electrically charged screen door, the burn marks caused by the mosquito killing, and the hearing sensitivity of the noise caused by the mosquito killing all increased slightly, but were still at a low level compared to Comparative Example 1.

[0042] In embodiment 3 of the present invention, as shown in FIG. 4, the intelligent voltage-adjustable charged screen door further includes a window frame 7, the positive electrode connector 3 and the negative electrode connector 4 are mounted inside the window frame 7, and the control system 2 is mounted on the window frame and located indoors.

[0043] In this embodiment, after the window frame 7 is attached, the electrically charged screen door can be used as usual.

[0044] In this embodiment, an experiment was conducted using an electrically charged screen door with a voltage of 200V. When the electrically charged screen door was placed in an environment containing mosquitoes, it was discovered through observation that there was no situation in which the mosquitoes would be killed by the electric shock, and there was also no situation in which the mosquitoes would pass through mesh arrangement 1, and in addition, the mosquitoes hardly ever touched the electrically charged screen door.

[0045] In this embodiment, an experiment was conducted using an electrically charged screen door with a voltage of 1,500V. When the electrically charged screen door was placed in an environment where there were mosquitoes, it was observed that the mosquitoes were immediately killed by an electric shock where they touched the electrically charged screen door, and some mosquitoes were shocked but survived. Compared to Example 2, there was a slight reduction in the number of mosquito corpses that were killed and stuck to the electrically charged screen door, the burn marks caused by the mosquito killing, and the hearing sensitivity of the noise caused by the mosquito killing.

[0046] In the fourth embodiment of the present invention, as shown in Fig. 5, the intelligent voltage-adjustable charged screen door further includes an ultraviolet light emitting device 8, which is mounted on the window frame 7 and located indoors, and the ultraviolet light emitting device 8 is independently electrically connected to a power source. When the temperature drops or rain falls outdoors, and mosquitoes are less likely to fly from indoors to outdoors, the ultraviolet light emitting device 8 can be turned on to attract mosquitoes to approach the charged screen door, thereby improving the mosquito-killing effect of the charged screen door against indoor mosquitoes.

[0047] In the fifth embodiment of the present invention, as shown in Fig. 6, the intelligent voltage-adjustable charged screen door further includes an electric device 9 for releasing mosquito attractant, which is mounted on the window frame 7 and located indoors, and is independently electrically connected to a power source. When the temperature drops or it rains outdoors, the electric device 9 for releasing mosquito attractant can be turned on to release mosquito sex pheromones, thereby attracting mosquitoes to approach the charged screen door, and improving the mosquito-killing effect of the charged screen door against indoor mosquitoes.

[0048] In the sixth embodiment of the present invention, as shown in FIG. 7, the intelligent voltage-adjustable charged screen door further includes a human body sensitive power cut-off device 10, which is installed in the integrated housing of the control system 2 with a probe exposed, and the input end of the human body sensitive power cut-off device 10 is electrically connected to one branch line of the output end of the relay 202, and the output end of the human body sensitive power cut-off device 10 is electrically connected to the input end of the second boost module 204. The voltage output from the power source is boosted by the second boost module 204 so that the voltage value on the mesh array 1 is in the range of 900 to 1950V, and if a person accidentally touches it, the mesh array 1 may cause unpleasant stimulation to people. Therefore, the human body sensitive power cut-off device 10 can be used to perform a power cut-off operation when it detects that a person is approaching the charged screen door, and the charged screen door can avoid causing unpleasant stimulation to people. For example, if the power cut-off distance is set to 50 cm, when the human body sensitive power cut-off device 10 detects that the distance between the human body and the charged screen door reaches 50 cm, it cuts off the power and removes the voltage on the mesh array 1.

[0049] The control system 2 controls the voltage on the mesh array 1 to be in the range of 900-1950V during the preset time periods of 5:00-7:30 and 17:00-19:00, and controls the voltage on the mesh array 1 to be in the range of 120-300V during other time periods. Based on the behavior of mosquitoes and a large amount of experimental observation, it is clear that mosquitoes tend to fly from indoors to outdoors during the time periods of 5:00-7:30 and 17:00-19:00, and these time periods are mainly for killing mosquitoes that want to fly out to outdoors through the electrified screen. It is clear that mosquitoes tend to fly from outdoors to indoors during the rest of the day, and these time periods are mainly for repelling mosquitoes that want to fly out to outdoors through the electrified screen.

[0050] The working process of the present invention is as follows: the mesh array is assembled, then the mesh array and the human body sensitive power cut-off device are well connected to the circuit of the control system, and then other components are connected to the power supply, and then the control system performs automatic control according to the preset value of the time control switch, and the mesh array changes the voltage independently in the corresponding time period. If the user thinks that the effect of the preset value is not good, the time control switch may be used to change the time period when the second boost module 204 and the first boost module 203 are turned on and off. If the time period when the second boost module 204 and the first boost module 203 are turned on and off needs to be manually switched, the user may use the time control switch to switch them. When it is necessary to kill mosquitoes, it is obvious that mosquitoes tend to fly from indoors to outdoors, so the ultraviolet light emitting device or the motorized device for emitting mosquito attractant is directly turned on to attract more mosquitoes to approach the charged screen door and kill them.

[0051] Finally, it should be clarified that the above embodiments are only used to interpret the technical solutions of the present invention, and do not limit it. Although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details may be made to the technical solutions of the present invention, but do not depart from the scope limited by the claims of the present invention.
