[0002] Mosquito killers are a common mosquito control device widely used in homes, public places, and outdoor activities. With the increase in outdoor activities, especially camping, wilderness exploration, and backyard parties, the demand for outdoor mosquito killers is growing.

[0003] Most existing outdoor mosquito killers use an electric heating principle, releasing mosquito-repelling ingredients by evaporating a liquid through external heating. However, existing outdoor mosquito killers have problems:

[0004] Most mosquito killers rely on heating elements that directly contact or remain heated for extended periods, which can lead to problems such as overheating of the heating element, uneven liquid evaporation, or the device operating in an unsafe condition. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a portable mosquito killer.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A portable mosquito killer is provided, comprising:

[0008] A first and second housing that are axially separable and dockable;

[0009] A volatile container, suitable for holding volatile liquids;

[0010] A evaporation mandrel has an insertion section located inside the evaporation container and an evaporation section located outside the evaporation container;

[0011] The electronic control components are disposed within the first housing;

[0012] An electric heating element is electrically connected to the electronic control assembly;

[0013] A sensing component, connected to the electronic control component, is used to detect the axial distance between the first housing and the second housing;

[0014] Furthermore, the electronic control component activates or deactivates the heating of the electric heating element based on the size of the axial spacing.

[0015] Preferably, the exposed length of the evaporation section is positively correlated with the axial spacing.

[0016] Preferably, the electronic control component controls the electric heating element to enter the heating state when the axial distance is greater than a preset threshold, and controls the electric heating element to stop heating when the axial distance is less than or equal to the preset threshold.

[0024] The evaporation zone has a mesh;

[0025] The evaporation section of the evaporation core rod is located within the evaporation region;

[0026] The evaporation container is detachably connected to the connection area, and the second housing is slidably connected to the connection area.

[0027] Preferably, the connecting area has a guide groove;

[0028] The inner wall surface of the second housing has a guide block;

[0041] This utility model provides a portable mosquito killer, and the beneficial effects of this utility model are reflected in:

[0042] The heating state of the electric heating element is determined by the axial distance between the first and second housings. An increase in the axial distance indicates that the user has separated the first and second housings, meaning the device is in use. In this state, the evaporation section of the vaporizing core is fully exposed to the external environment, achieving efficient evaporation and improving mosquito-killing effectiveness. A decrease in the axial distance indicates that the first and second housings are gradually coming together, meaning the device is in a non-use or stored state. At this time, the evaporation section of the vaporizing core is gradually blocked or completely hidden inside the housing. The electronic control components control the electric heating element to stop heating based on the change in axial distance, thereby reducing unnecessary consumption of the evaporating liquid, extending the device's lifespan, and improving safety.

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0058] Please see Figures 1-12 As shown, the specific embodiments provided by this utility model are as follows:

[0059] This portable mosquito killer is suitable for killing mosquitoes and insects, and can be used at home or outdoors.

[0060] refer to Figures 1 to 4 As shown, the portable mosquito killer includes a device housing 1. The device housing 1 includes a first housing 101 and a second housing 102 that are axially separable and dockable. It should be understood that when a tensile force is applied to one or both housings, the two housings move relative to each other in the axial direction. Correspondingly, when a thrust is applied, the two housings move docking with each other in the axial direction.

[0061] refer to Figures 6 to 8 As shown, the portable mosquito killer includes an evaporation container 2. The evaporation container 2 is used to hold evaporating liquid, such as mosquito-repellent liquid. The opening of the evaporation container 2 is sealed by a sealant 201. The sealant 201 can be made of rubber. A liquid-absorbing ring 202 is fitted onto the opening. The liquid-absorbing ring 202 has the property of absorbing liquid.

[0062] refer to Figure 5 As shown, it includes a evaporation mandrel 3. The evaporation mandrel 3 is inserted into the evaporation container 2 through a sealing member 201 (with an insertion port at the center). The evaporation mandrel 3 located inside the evaporation container 2 is the insertion section 301, and the evaporation mandrel 3 located outside the evaporation container 2 is the evaporation section 302. It should be understood that there is no significant difference between the insertion section 301 and the evaporation section 302; they are simply different parts of the same evaporation mandrel 3. The insertion section 301 is mainly used for liquid absorption, while the evaporation section 302 is the part where the liquid evaporates. This distinction is more for describing the different functional areas of the evaporation mandrel 3 than for functional differences.

[0063] refer to Figure 5 As shown, the portable mosquito killer includes an electric heating element 4. The electric heating element 4 is connected to an electronic control component. The electronic control component provides electrical power to the electric heating element 4 and performs electronic control management. Specifically, the electronic control component is responsible for controlling the heating of the electric heating element 4 on and off. When on, the electronic control component provides current to the electric heating element 4 through a power supply interface and controls its temperature rise.

[0064] In one usage state, the electric heating element 4 is adapted to be inserted into the evaporation core rod 3. Specifically, the evaporation core rod 3 has an inner cavity 303, and a first opening 304 is formed at one end of the evaporation section 302, while the end of the insertion section 301 is closed. The electric heating element 4 is inserted into the inner cavity 303 through the first opening 304, without directly contacting the inner wall surface of the inner cavity 303. By heating the air in the inner cavity 303 (and a small amount of gas after the evaporation of the volatile liquid), the heated air in the inner cavity 303 actively diffuses from the inside of the inner cavity 303 to the external environment, and drives the evaporation liquid adsorbed by the evaporation section 302 to evaporate.

[0065] In one specific embodiment, a sealing body 7 is also included. The sealing body 7 has a cone-like structure and is sleeved on the end of the electric heating element 4. When the electric heating element 4 is inserted into the evaporation core rod 3, the sealing body 7 seals the first opening 304, so that the inner cavity is in a sealed state.

[0066] In another usage configuration, the electric heating element 4 is adapted to be disposed around the periphery of the evaporation core rod 3 for heating the evaporation core rod 3.

[0067] In one specific embodiment, in the use state, the electronic control component is disposed within the first housing 101. For example, the first housing 101 contains a battery compartment, and the electronic control component is disposed within the battery compartment. One end of the electric heating element 4 is electrically connected to the electronic control component, and the other end is located outside the first housing 101. The evaporation container 2 is located within the second housing 102. When the first housing 101 and the second housing 102 are axially separated, the evaporation section 302 of the evaporation core rod 3 is gradually exposed to the external environment until it is completely exposed. Correspondingly, when the first housing 101 and the second housing 102 are axially connected, the evaporation section 302 of the evaporation core rod 3 is gradually hidden. It should be understood that in the use state, the evaporation section 302 of the evaporation core rod 3 is located between the first housing 101 and the second housing 102 (in the axial direction), thus, during the separation or connection of the first housing 101 and the second housing 102, the evaporation section 302 will be exposed to the external environment or hidden between the first housing 101 and the second housing 102.

[0068] Based on the above, the portable mosquito killer includes a sensing component (not shown in the figure), which is connected to the electronic control component, for example, through a circuit connection or a signal connection. The sensing component is used to sense the axial distance between the first housing 101 and the second housing 102. The electronic control component can then control the power supply to the electric heating element 4 based on this axial distance, i.e., turn on the heating state of the electric heating element 4 or turn off the heating state of the electric heating element 4.

[0069] In one embodiment, the sensing component includes a magnetic element and a magnetic field sensing element, such as a Hall sensor. Specifically, the magnetic element is disposed in the second housing 102, and the magnetic field sensing element is disposed in the first housing 101. When the second housing 102 moves axially relative to the first housing 101, the magnetic field sensing element detects the change in the magnetic field strength of the magnetic element and transmits the detection signal to the electronic control component. The electronic control component calculates the axial spacing based on the change in magnetic field strength and controls the opening and closing state of the electric heating element 4 accordingly.

[0070] In one specific embodiment, when the axial spacing is greater than a set threshold, the electronic control component controls the electric heating element 4 to be in a heating state; when the axial spacing is less than or equal to the set threshold, the electronic control component controls the electric heating core to be in a stopped heating state.

[0071] In one specific embodiment, the threshold is set to 1 mm. That is, when the first housing 101 and the second housing 102 just begin to separate axially, the electronic control component controls the electric heating element 4 to start heating, and when the first housing 101 and the second housing 102 are fully connected, the electronic control component controls the electric heating element 4 to stop heating.

[0072] In one specific embodiment, the threshold is set to 4 mm. That is, when the axial distance between the first housing 101 and the second housing 102 is greater than 4 mm, the electronic control component starts to control the electric heating component to be in a heating state, and when the axial distance is less than or equal to 4 mm, the electronic control component controls the electric heating element 4 to be in a stopped heating state.

[0073] In one specific implementation, the threshold can also be any value between 1mm and 10mm, such as 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm.

[0074] Of course, the threshold can also be set to exceed 10mm, such as 11mm or 12mm. In this case, the length of the evaporation core rod 3 will increase simultaneously, and the length of the evaporation section 302 will also increase simultaneously. This means that the adhesion area of ​​the evaporating liquid in the evaporation section 302 will increase, thereby improving the evaporation effect.

[0075] The advantage of this structure is that the heating state of the electric heating element 4 is determined by the axial distance between the first housing 101 and the second housing 102. When the axial distance increases, it means the user has separated the first housing 101 and the second housing 102, i.e., the device is in use. In this state, the evaporation section 302 of the evaporation core 3 is fully exposed to the external environment, and the electric heating element 4 is inserted into the evaporation core 3, thereby achieving efficient evaporation and improving the mosquito-killing effect. When the axial distance decreases, it means the first housing 101 and the second housing 102 are gradually connected, i.e., the device is in a non-use or stored state. At this time, the evaporation section 302 of the evaporation core 3 is gradually blocked or completely hidden inside the housing. The electronic control component controls the electric heating element 4 to stop heating based on the change in axial distance, thereby reducing unnecessary consumption of the evaporating liquid, extending the device's service life, and improving safety.

[0076] In one specific embodiment, a lighting lamp is also included, disposed in the first housing 101 or the second housing 102, and located near the evaporation core rod 3, preferably above the evaporation section 302 of the evaporation core rod 3. Furthermore, the lighting lamp can be turned on and off based on the size of the axial gap. For example, when the axial gap reaches 1 mm, the lighting lamp is turned on synchronously with the heating of the electric heating element 4. Conversely, when the axial gap decreases to a set threshold, the lighting lamp is turned off.

[0077] refer to Figures 9 to 12 As shown, in one specific embodiment, the portable mosquito killer includes a protective mesh cover 5. The protective mesh cover 5 has an evaporation area 501. The evaporation area 501 has mesh openings, such as circular or diamond-shaped openings.

[0078] In use, the evaporation section 302 of the evaporation core rod 3 is located within the evaporation zone 501.

[0079] The protective mesh cover 5 also has a connection area 502. The second housing 102 is slidably connected to the outer peripheral surface of the connection area 502, and the evaporation container 2 is connected to the inner peripheral surface of the connection area 502.

[0080] The upper end of the evaporation region 501 is fixedly connected to the first housing 101. It should be understood that, in use, the second housing 102 can be pushed or pulled, causing the second housing 102 to slide relative to the connection region 502, that is, relative to the first housing 101, so that the evaporation region 501 is gradually exposed to the external environment or hidden inside the second housing 102, that is, the evaporation section 302 of the evaporation core rod 3 is exposed to the external environment or hidden inside the second housing 102.

[0081] The connecting area 502 has a guide groove 5021. Correspondingly, the inner wall surface of the second housing 102 is provided with a guide block, which is slidably connected to the guide groove 5021, so that the second housing 102 and the connecting area 502 form a sliding connection.

[0082] The guide groove 5021 is zigzag-shaped along the axial direction of the protective mesh cover 5. That is, the guide groove 5021 includes a first track, a second track, and a third track. The three tracks form a zigzag line. Taking the sliding of the second housing 102 as an example, firstly, in the first stage, the second housing 102 moves away from the first housing 101 along the axial direction. At this time, the guide block slides within the third track, and the exposed length of the evaporation area 501 gradually increases. When the guide block reaches the end of the third track, it is blocked by the second track, which is perpendicular or nearly perpendicular to the third track. At this point, further pulling of the second housing 102 along the axial direction will be blocked, and the evaporation area 501 will be completely exposed. To remove the second housing 102, such as to add or replace the mosquito-repellent liquid in the evaporation container 2, the second housing 102 needs to be rotated, causing the guide block to slide along the second track until it reaches the end of the second track, which is the beginning of the first track. Generally speaking, it can be rotated 30°. When the guide block is at the starting point of the first track, the second housing 102 can continue to be pulled along the axis, so that the guide block continues to slide along the first track until the second housing 102 is completely separated from the connecting area 502.

[0083] The first and third tracks are arranged along the axial direction of the protective net cover 5, and the second track is arranged perpendicular to or nearly perpendicular to the first and third tracks.

[0084] The protective mesh cover 5 includes a slot 5022, and correspondingly, the evaporation container 2 has a locking block on its circumferential wall near the bottom. When the evaporation container 2 is inserted into the connection area 502, the locking block and the slot 5022 engage to limit the insertion depth of the evaporation container 2.

[0085] The protective mesh cover 5 includes a first elastic deformable block 5023, which is stamped and formed by the protective mesh cover 5 and has a certain degree of elasticity. The first deformable block 5023 has a small protrusion protruding towards the evaporation container 2, and correspondingly, the outer wall surface of the evaporation container 2 has an inwardly recessed groove. When the evaporation container 2 is inserted to a set depth, the first deformable block 5023 and the groove engage to prevent the evaporation container 2 from detaching from the connection area 502.

[0086] The protective mesh cover 5 includes a resilient second deformable block 5024, which has the same structure as the first deformable block 5023, except that the small protrusions of the second deformable block 5024 protrude towards the inner wall surface of the second housing 102. Correspondingly, the inner wall surface of the second housing 102 has a recessed groove. When the second housing 102 is fully engaged with the first housing 101, the second deformable block 5024 engages with the groove to prevent the second housing 102 from detaching. Alternatively, when the second housing 102 moves to the point where the evaporation area 501 is fully exposed, the second deformable block 5024 engages with the groove.

[0087] The protective mesh cover 5 includes an observation slot 602, and correspondingly, the second housing 102 includes an observation window 601. When the second housing 102 and the first housing 101 are fully aligned, the observation window 601 and the observation slot 602 are positioned accordingly, allowing the user to observe the remaining liquid in the evaporation container 2 through the observation window 601.
