Description

Technical Field

[0001] The utility model relates to the technical field of mosquito killing devices, in particular to a gas enrichment component and a mosquito killer.

Technical Background

[0002] In the field of public health, mosquitoes are a well-known disease transmission vector, which threatens human life and health to a certain extent and affects the quality of human life. Therefore, effective mosquito control is of great significance. Traditional mosquito control methods, such as mosquito coils and mosquito liquid, mainly rely on releasing mosquito-killing chemical substances to kill mosquitoes. The chemical substances are highly toxic to the human body, so new mosquito control methods are gradually emerging.

[0003] Existing mosquito killers can eliminate mosquitoes by discharging carbon dioxide gas at a predetermined concentration. However, the discharged carbon dioxide gas will gradually dissipate over time. To avoid waste of carbon dioxide gas, existing mosquito killers usually set up a fan to adsorb the discharged carbon dioxide gas back within a certain period of time. However, when the fan adsorbs carbon dioxide gas, it will also adsorb air back at the same time. At this time, the concentration of carbon dioxide gas is bound to decrease. Even if it is discharged again, its concentration will greatly reduce the mosquito control effect. Therefore, there is a problem in existing mosquito killers that the concentration of carbon dioxide gas cannot be stored, resulting in a low concentration of the recycled carbon dioxide gas and a poor mosquito control effect of the finally recycled carbon dioxide gas.

[0009] Preferably, when the rotating mechanism rotates in the reverse direction, the first exhaust structure is opened, and the adsorbed carbon dioxide gas is discharged from the enrichment cavity to the exhaust cavity.

[0016] Compared with the prior art, the gas enrichment component and the mosquito killer provided by the present utility model have the following advantages:

[0017] 1. A gas enrichment component provided by an embodiment of the present utility model is used to enrich carbon dioxide gas in the air. The gas enrichment component includes a housing, a ventilation device, an enrichment component and an air extraction device connected in sequence; an accommodation cavity with an opening is defined inside the housing, and the ventilation device is arranged in the accommodation cavity near the opening; the enrichment component includes at least two enrichment bodies, a placement net through which air can pass, and a carbon dioxide adsorption material. The enrichment bodies are arranged on the side of the ventilation device away from the opening, and at least two enrichment bodies surround to form an exhaust cavity.

[0018] An enrichment cavity is arranged inside the enrichment body, a placement net is arranged in the enrichment cavity, the carbon dioxide adsorption material is laid on the placement net, an air inlet structure, a first exhaust structure and a second exhaust structure are arranged on the enrichment body, the enrichment cavity is communicated or closed with the outside of the housing through the air inlet structure, the enrichment cavity is communicated or closed with the exhaust cavity through the first exhaust structure, and the enrichment cavity is communicated or closed with the air extraction device through the second exhaust structure. The carbon dioxide gas discharged in this embodiment of the gas enrichment component is enriched again, that is, the carbon dioxide gas will be successfully recovered, and the carbon dioxide concentration recovered by it will not reduce the mosquito killing effect when released again.

[0019] 2. The ventilation device of the present utility model includes a fixing frame connected to the housing and a rotating mechanism rotatably connected to the fixing frame. The rotating direction of the rotating mechanism includes a forward direction and a reverse direction; an air inlet cavity is arranged between the ventilation device and the enrichment component, and the air inlet cavity is communicated with the exhaust cavity. The air inlet cavity serves as a buffer area, which can allow the carbon dioxide gas in the exhaust cavity to be slowly released into the air suction cavity first, and then be discharged to the outside through the opening of the housing by the air suction cavity.

[0020] 3. When the rotating mechanism rotates in the forward direction, the air near the opening outside the housing is inhaled into the enrichment cavity after passing through the air inlet cavity. The air inlet structure, the first exhaust structure and the second exhaust structure are closed to seal the enrichment cavity, and the carbon dioxide adsorption material adsorbs the carbon dioxide gas in the air. When the rotating mechanism rotates in the reverse direction, the first exhaust structure is opened, and the adsorbed carbon dioxide gas is discharged from the enrichment cavity to the exhaust cavity. The carbon dioxide gas in the exhaust cavity is discharged from the opening to the outside of the housing after passing through the air inlet cavity. By matching the rotating direction of the rotating mechanism with the gas enrichment process, the enrichment work of carbon dioxide is realized, which is simple and convenient.

[0021] 4. The gas enrichment component of the present utility model includes a control device. The intake structure includes an intake passage and an intake switch. The intake passage communicates with the enrichment chamber and the intake chamber. The intake switch is disposed in the intake passage and electrically connected to the control device to conduct or block the intake passage. The intake structure is automatically controlled by the control device, with high automation.

[0022] 5. The first exhaust structure of the present utility model includes a first exhaust passage and a first exhaust switch. The first exhaust passage communicates with the enrichment chamber and the exhaust chamber. The first exhaust switch is disposed in the first exhaust passage and electrically connected to the control device to conduct or block the first exhaust passage. The first exhaust structure is automatically controlled by the control device, with high automation.

[0023] 6. The second exhaust structure of the present utility model includes a second exhaust passage and a second exhaust switch. The second exhaust passage communicates with the enrichment chamber and the air extraction device. The second exhaust switch is disposed in the second exhaust passage and electrically connected to the control device to conduct or block the second exhaust passage. The second exhaust structure is automatically controlled by the control device, with high automation.

[0024] 7. The number of the first exhaust switches corresponding to the enrichment body of the present utility model is at least two, and the control device controls each exhaust switch to conduct or block separately, so that the carbon dioxide gas in the enrichment chamber is discharged into the exhaust chamber. The enrichment of carbon dioxide gas by the enrichment body can be selectively controlled through the first exhaust switch located on the enrichment housing, with high selectivity.

[0025] 8. The gas enrichment component of the present utility model further includes a temperature control module. The placement net is electrically connected to the temperature control module to control the temperature of the upper surface of the placement net. Due to the structure of the exhaust chamber, when the carbon dioxide gas in the exhaust chamber is sucked out and discharged outside the housing, all the placement nets and carbon dioxide adsorption materials in the enrichment chambers can be quickly cooled together. Thereby, the efficiency of enriching carbon dioxide gas is improved.

[0026] 9. The solution for the present utility model to solve the technical problem is to further provide a mosquito killer, which has the same beneficial effects as the above-mentioned gas enrichment component and will not be elaborated here.

[0045] Existing mosquito killers can eliminate mosquitoes by emitting carbon dioxide gas at a predetermined concentration. However, the emitted carbon dioxide gas will gradually dissipate over time. In order to avoid waste of carbon dioxide gas, existing mosquito killers usually set up a fan to adsorb the emitted carbon dioxide gas back within a certain period of time. However, when the fan adsorbs carbon dioxide gas, it will also adsorb air back at the same time, and at this time the concentration of carbon dioxide gas is bound to decrease. Therefore, based on the prior art to recycle the released carbon dioxide gas, even if the recycled carbon dioxide gas is emitted again, its concentration will be greatly reduced for the effect of eliminating mosquitoes. Therefore, existing mosquito killers have the problem that the concentration of the recycled carbon dioxide gas is low, or it is unable to concentrate the carbon dioxide gas, resulting in a low concentration of the recycled carbon dioxide gas, leading to a poor mosquito elimination effect of the finally recycled carbon dioxide gas.

[0046] To solve the above technical problems, please combine Figure 1 and Figure 2 In the first embodiment of the present utility model, a gas enrichment assembly 10 is provided for enriching carbon dioxide gas in the air. The gas enrichment assembly 10 includes a housing 1, a ventilation device 2, an enrichment assembly 3 and an air extraction device 4 connected in sequence; a receiving cavity with an opening 11 is defined inside the housing 1, and the ventilation device 2 is disposed in the receiving cavity near the opening 11; the enrichment assembly 3 includes at least two enrichment bodies 31, a placement net 32 through which air can pass, and a carbon dioxide adsorption material 33. The enrichment bodies 31 are disposed on the side of the ventilation device 2 away from the opening 11, and at least two enrichment bodies 31 surround to form an exhaust cavity 12;

[0047] An enrichment cavity 34 is provided inside the enrichment body 31. The placement net 32 is disposed in the enrichment cavity 34, and the carbon dioxide adsorption material 33 is laid on the placement net 32. An air inlet structure 35, a first exhaust structure 36 and a second exhaust structure 37 are provided on the enrichment body 31. The enrichment cavity 34 is communicated with or closed to the outside of the housing 1 through the air inlet structure 35, the enrichment cavity 34 is communicated with or closed to the exhaust cavity 12 through the first exhaust structure 36, and the enrichment cavity 34 is communicated with or closed to the air extraction device 4 through the second exhaust structure 37.

[0048] It should be understood that an air tank (not shown in the figure) for storing carbon dioxide gas is further provided inside the gas enrichment assembly 10 in this embodiment, and one end of the air tank is communicated with the exhaust cavity 12. When the gas enrichment assembly 10 in this embodiment starts to work initially, the air tank will transport carbon dioxide gas with a predetermined concentration into the exhaust cavity 12. After the ventilation device 2 starts to work, the suction force provided by the ventilation device 2 forces the carbon dioxide gas in the exhaust cavity 12 to be discharged from the opening 11 of the housing 1 to the outside of the housing 1 to attract mosquitoes outside. It should be understood that the concentration of carbon dioxide gas required to attract mosquitoes during the mosquito extermination process is set to A 1 ppm, where ppm is a unit of gas concentration, usually referring to mole fraction or volume fraction. In order to make the concentration of the recycled carbon dioxide gas close to A1 ppm when it is discharged again, the above-mentioned carbon dioxide gas with a predetermined concentration is usually much greater than A1 ppm. When the carbon dioxide gas is discharged from the opening 11, the concentration of the carbon dioxide gas with a predetermined concentration will drop sharply. If the prior art is used to recycle carbon dioxide gas, the concentration of the recycled carbon dioxide gas will be lower than A1 ppm, that is, the problem that the recycled carbon dioxide gas cannot attract mosquitoes will occur.

[0049] Specifically, the gas enrichment component 10 provided in this embodiment can enrich the discharged carbon dioxide gas. After the initial discharge of the gas cylinder, the carbon dioxide gas will gather at the opening 11 of the housing 1 to attract mosquitoes. When the gas enrichment component 10 needs to enrich the carbon dioxide gas, first, the intake structure 35 is in a connected state, that is, the enrichment chamber 34 is connected to the outside of the housing 1, and the ventilation device 2 starts to work. It provides suction force to force the carbon dioxide gas at the opening 11 of the housing 1 together with the air to be inhaled into the enrichment chamber 34. During this process, a placement net 32 is arranged inside the enrichment chamber 34, and the carbon dioxide adsorption material 33 on the placement net 32 will absorb the carbon dioxide gas inside the enrichment chamber 34, thereby causing the concentration of carbon dioxide gas in the enrichment chamber 34 to drop sharply. After a period of time, the adsorption of the carbon dioxide adsorption material 33 reaches saturation.

[0050] Further, after the adsorption of the carbon dioxide adsorption material 33 reaches saturation, the intake structure 35 and the first exhaust structure 36 are controlled to be in a closed state, that is, the enrichment chamber 34 is not connected to the outside of the housing 1 and the exhaust chamber 12. And the second exhaust structure 37 is controlled to be in a connected state, that is, the enrichment chamber 34 is connected to the air extraction device 4. It should be understood that the air extraction device 4 is used to extract the air inside the enrichment chamber 34 and the excess carbon dioxide that has not been adsorbed by the carbon dioxide adsorption material 33. The result of the air extraction process is to reduce the pressure inside the enrichment chamber 34.

[0051] Further, after the air extraction device 4 stops working, the second exhaust structure 37 can be controlled to be switched from a connected state to a closed state, that is, the enrichment chamber 34 is not connected to the air extraction device 4. At this time, the carbon dioxide adsorbed in the carbon dioxide adsorption material 33 can be re-discharged into the enrichment chamber 34 by heating the carbon dioxide adsorption material 33. Since the air inside the enrichment chamber 34 has been extracted by the air extraction device 4, the carbon dioxide gas re-discharged by the carbon dioxide adsorption material 33 will have a higher concentration. In addition, since the air extraction device 4 creates a low-pressure environment inside the enrichment chamber 34 when extracting air, the low-pressure environment can also accelerate the efficiency of the carbon dioxide adsorption material 33 in discharging carbon dioxide gas. It should be noted that in one embodiment of the above method of heating the carbon dioxide adsorption material 33, the placement net 32 is made of a metal material. In this embodiment, the placement net 32 can be directly heated, and after the placement net 32 is heated, the heat is transferred to the carbon dioxide adsorption material 33 to accelerate the release of the carbon dioxide gas adsorbed inside the carbon dioxide adsorption material 33. In another embodiment, a hot air blower (not shown) for providing hot air is arranged inside the enrichment chamber 34. When the hot air blower is working, the temperature inside the enrichment chamber 34 rises, forcing the carbon dioxide adsorption material 33 placed on the placement net 32 to release the carbon dioxide gas adsorbed inside it.

[0052] Further, when the carbon dioxide adsorption material 33 releases the carbon dioxide gas adsorbed inside it, since the air in the enrichment chamber 34 has been pumped out by the pumping device 4, the carbon dioxide concentration inside the enrichment chamber 34 will be close to the carbon dioxide concentration initially released from the gas cylinder at this time. Specifically, the intake structure 35 and the second exhaust structure 37 are controlled to be in a closed state, and the first exhaust structure 36 is in a connected state. That is, the enrichment chamber 34 is in a non-connected state with the pumping device 4 and the outside of the housing 1, while the enrichment chamber 34 is in a connected state with the exhaust chamber 12. At this time, the carbon dioxide gas in the enrichment chamber 34 will be discharged into the exhaust chamber 12. Then the ventilation device 2 starts to work and provides suction to discharge the carbon dioxide gas in the exhaust chamber 12 back to the outside of the housing 1 through the opening 11. It should be noted that since the air in the enrichment chamber 34 is pumped away by the pumping device 4, in a possible implementation, although the carbon dioxide adsorption material 33 releases carbon dioxide gas again, there may be a pressure difference between the inside of the enrichment chamber 34 and the discharge chamber. At this time, the gas cylinder can be controlled to discharge some more carbon dioxide to make up for the above-mentioned pressure difference. Specifically, since the gas enrichment assembly 10 in this embodiment re-enriches the discharged carbon dioxide gas, that is, the carbon dioxide gas will be successfully recovered, and the recovered carbon dioxide concentration will not reduce the mosquito killing effect when released again.

[0053] It should be noted that in this embodiment, the connected state of the intake structure 35, the first exhaust structure 36, and the second exhaust structure 37 means that one chamber is connected to another chamber or device, so that the gas in this chamber can be transported to another chamber or device. On the contrary, the closed state means that the gas in this chamber cannot be transported to another chamber or device. The intake structure 35, the first exhaust structure 36, and the second exhaust structure 37 can be in a connected state or a closed state through manual control or automatic control, which will not be elaborated here. In addition, in one implementation, the placement net 32 can be arranged in the enrichment chamber 34 without contacting the inner wall surface of the enrichment chamber 34. Please refer to Figure 3 and Figure 5 , in another implementation, the placement net 32 can also be arranged in the enrichment chamber 34 in contact with the inner wall surface of the enrichment chamber 34. In yet another implementation, the placement net 32 can also be buried in the inner wall surface of the enrichment chamber 34, and part of the placement net 32 is exposed on the surface of the inner wall surface.

[0054] Further, please refer to Figure 1 and Figure 7, the ventilation device 2 includes a fixing frame 21 connected to the housing 1 and a rotating mechanism 22 rotatably connected to the fixing frame 21. The rotating direction of the rotating mechanism 22 includes a forward direction and a reverse direction. An intake cavity 13 is provided between the ventilation device 2 and the enrichment assembly 3, and the intake cavity 13 communicates with the exhaust cavity 12. It should be understood that the ventilation device 2 is used to discharge the carbon dioxide gas in the exhaust cavity 12 to the outside of the housing 1, or to suck the carbon dioxide gas together with air near the opening 11 of the housing 1 into the enrichment cavity 34. The intake cavity 13 serves as a buffer area, allowing the carbon dioxide gas in the exhaust cavity 12 to be slowly released into the intake cavity first, and then discharged to the outside through the opening 11 of the housing 1 by the intake cavity.

[0055] Specifically, the rotating direction of the rotating mechanism 22 includes a forward direction and a reverse direction. The rotating direction refers to the direction in which the rotating mechanism 22 rotates circumferentially along the axis of the fixing frame 21.

[0056] Exemplarily, when the rotating mechanism 22 rotates in the forward direction, the air outside the housing 1 near the opening 11 is sucked into the enrichment cavity 34 after passing through the intake cavity 13. The intake structure 35, the first exhaust structure 36, and the second exhaust structure 37 are closed to seal the enrichment cavity 34, and the carbon dioxide adsorption material 33 completes the adsorption of the carbon dioxide gas in the air. It should be understood that when the gas enrichment assembly 10 performs the enrichment work, first, the intake structure 35 is controlled to open, so that the enrichment cavity 34 and the intake cavity 13 communicate. At this time, the carbon dioxide adsorption material 33 in the enrichment cavity 34 has already started to adsorb the carbon dioxide gas in the air. When the intake structure 35, the first exhaust structure 36, and the second exhaust structure 37 are closed to seal the enrichment cavity 34, the carbon dioxide adsorption material 33 has completed the adsorption work.

[0057] Exemplarily, when the rotating mechanism 22 rotates in the reverse direction, the first exhaust structure 36 is opened, and the adsorbed carbon dioxide gas is discharged from the enrichment cavity 34 into the exhaust cavity 12. The carbon dioxide gas in the exhaust cavity 12 is discharged to the outside of the housing 1 through the intake cavity 13 and the opening 11. It should be understood that after the air in the enrichment cavity 34 is extracted by the air extraction device 4, the carbon dioxide adsorption material 33 can be heated. At this time, the carbon dioxide adsorbed inside the carbon dioxide adsorption material 33 will be released into the enrichment cavity 34. After the first exhaust structure 36 is opened, the adsorbed carbon dioxide gas is discharged from the enrichment cavity 34 into the exhaust cavity 12. When the rotating mechanism 22 rotates in the reverse direction, the suction force it provides can discharge the carbon dioxide gas in the exhaust cavity 12 through the intake cavity 13 and the opening 11 to the outside of the housing 1 to attract mosquitoes, which is simple and convenient.

[0058] It should be understood that in this embodiment, by the forward or reverse rotation of the rotating mechanism 22, it is determined whether to inhale carbon dioxide gas together with air into the enrichment chamber 34 through the suction chamber, or to discharge the enriched carbon dioxide gas from the enrichment chamber 34 through the exhaust chamber 12 and the suction chamber in sequence to the outside of the housing 1. That is, in this embodiment, by coordinating the rotation direction of the rotating mechanism 22 with the gas enrichment process, the enrichment work of carbon dioxide is realized, which is simple and convenient.

[0059] Further, please refer to Figure 1 , Figure 7 and Figure 8 , the gas enrichment assembly 10 includes a control device (not shown), the intake structure 35 includes an intake passage and an intake switch, the intake passage communicates with the enrichment chamber 34 and the intake chamber 13, and the intake switch is disposed in the intake passage and electrically connected to the control device to conduct or block the intake passage. It should be understood that when the control device controls the intake switch to open, the carbon dioxide gas outside the housing 1 together with air can enter the suction chamber under the action of the ventilation device 2 first, and then enter the enrichment chamber 34 from the suction chamber through the intake passage.

[0060] Further, please refer to Figure 1 and Figure 6 , the second exhaust structure 37 includes a second exhaust passage and a second exhaust switch, the second exhaust passage communicates with the enrichment chamber 34 and the pumping device 4, and the second exhaust switch is disposed in the second exhaust passage and electrically connected to the control device to conduct or block the second exhaust passage. It should be understood that when the control device controls the second exhaust switch to open, the air in the enrichment chamber 34 can be inhaled into the exhaust device through the second exhaust passage under the action of the pumping device 4.

[0061] Further, the first exhaust structure 36 includes a first exhaust passage and a first exhaust switch, the first exhaust passage communicates with the enrichment chamber 34 and the exhaust chamber 12, and the first exhaust switch is disposed in the first exhaust passage and electrically connected to the control device to conduct or block the first exhaust passage. It should be understood that when the control device controls the first exhaust switch to open, the carbon dioxide gas in the enrichment chamber 34 enters the exhaust chamber 12 through the first exhaust passage, and under the action of the ventilation device 2, the carbon dioxide gas in the exhaust chamber 12 is discharged to the outside of the housing 1 through the suction chamber.

[0062] Specifically, there are at least two first exhaust switches provided corresponding to the enrichment body 31, and the control device controls each exhaust switch to be individually turned on or closed, so that the carbon dioxide gas in the enrichment chamber 34 is discharged into the exhaust chamber 12. It should be understood that since the discharge chamber in this embodiment is formed by enclosing at least two enrichment bodies 31. In a possible implementation manner, the at least two enrichment bodies 31 in this embodiment can perform the above process of enriching carbon dioxide gas together, or in batches. Exemplarily, the figure shows four enrichment bodies 31. Since mosquitoes are likely to appear in the morning or evening time periods, in the morning and evening, the four enrichment bodies 31 can simultaneously enrich carbon dioxide gas, and then, during the time period when mosquitoes appear more frequently, the carbon dioxide is centrally discharged, so that the amount of carbon dioxide discharged is increased, enhancing the effect of attracting mosquitoes. And during the remaining time when mosquitoes appear less frequently, by controlling the opening time of multiple first exhaust switches in batches, the four enrichment bodies 31 can take turns to perform the carbon dioxide gas enrichment work, so that the carbon dioxide stored inside the enrichment body 31 can be continuously released for a long time when there are few mosquitoes. That is, in this embodiment, the enrichment of carbon dioxide gas by the enrichment body 31 can be selectively controlled by the first exhaust switch located on the enrichment housing 1, with a high selectivity.

[0063] Preferably, please also refer to Figure 8 , the gas enrichment assembly 10 further includes a temperature control module, and the placement net 32 is electrically connected to the temperature control module to control the temperature of the upper surface of the placement net 32. In this embodiment, the placement net 32 is made of a metal material, and the placement net 32 can be directly heated, which is simple and convenient. After the placement net 32 is heated, it transfers heat to the carbon dioxide adsorption material 33 to accelerate the release of the carbon dioxide gas adsorbed inside the carbon dioxide adsorption material 33.

[0064] Further, whether the carbon dioxide adsorption material 33 adsorbs or releases carbon dioxide depends on the pressure and temperature of the environment where the carbon dioxide adsorption material 33 is located. Generally, when the carbon dioxide adsorption material 33 is higher than the preset temperature, it releases carbon dioxide gas, and when it is lower than the preset temperature, it absorbs carbon dioxide gas. Since there are multiple enrichment bodies 31 in this embodiment, when the first exhaust structures 36 corresponding to the multiple enrichment bodies 31 are connected simultaneously, the carbon dioxide gas in the multiple enrichment chambers 34 is discharged into the discharge chamber together, and the placement net 32 and the carbon dioxide adsorption material 33 in the discharge chamber can be cooled as soon as possible together. It should be understood that the multiple enrichment bodies 31 in this embodiment enclose to form the exhaust chamber 12. Thanks to the structure of the exhaust chamber 12, when the carbon dioxide gas in the exhaust chamber 12 is discharged outside the housing 1, the placement nets 32 and the carbon dioxide adsorption materials 33 in all the enrichment chambers 34 can be quickly cooled together. Thereby, the efficiency of enriching carbon dioxide gas is improved.

[0065] Further, during the process of enriching carbon dioxide gas, the temperature control module provided in this embodiment can also effectively reduce the water content in the carbon dioxide adsorbent. Exemplarily, at night or in the early morning, the air humidity is relatively high, which results in a high water content in the carbon dioxide adsorbent. That is, when the carbon dioxide adsorbent adsorbs too much water, it may cause the adsorption sites of carbon dioxide gas to be blocked, greatly reducing the adsorption amount of carbon dioxide gas. By controlling the temperature control module to heat the carbon dioxide adsorbent, the water inside it can be removed, which helps to reduce the water content in the carbon dioxide adsorbent.

[0066] It should be noted that the intake switch, the first exhaust switch, and the second exhaust switch described in this embodiment can use gas switches. For example, they can be gas cocks, gas switches, or electronic flow switches. Therefore, no specific illustrations are provided and no further elaboration is made here.

[0067] The gas enrichment assembly 10 provided in this embodiment can be widely applied in a carbon-rich agricultural implement, a mosquito killer, and a carbon dioxide recycling device. That is, the gas enrichment assembly 10 in this embodiment can be widely applied in the fields of agriculture, environmental protection industry, and mosquito control, and it has the function of a wide range of application scenarios.

[0068] The second embodiment of the present utility model also provides a mosquito killer, which includes a base and the above-mentioned gas enrichment assembly 10 connected to the base.

[0069] It can be understood that the mosquito killer provided in this embodiment has the same technical effects as the above-mentioned gas enrichment assembly 10, so no further elaboration is made here.

[0070] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the principle of the present utility model shall be included within the protection scope of the present utility model.
