[0044] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0045] By analyzing the prior art, the inventors found that: after the existing mosquito sampling trap device releases the attractant source, the attractant source will directly fall or be blown away by the wind, and it is unable to effectively enrich the released attractant source. The diffusion and loss of the attractant source are relatively serious, resulting in poor trapping effect and being unfavorable for carrying out sampling work in the wild. At the same time, the existing mosquito sampling trap devices are usually relatively complex in structure or large in size, with great difficulty in layout and inconvenient installation. Even if some trap devices have the function of folding for storage, the folding process is relatively complex and the folding effect is not good, still causing inconvenience in use.

[0046] It should be noted that in any embodiment of the present application, the attractant source referred to in the present application can be a gas attractant source, mainly including carbon dioxide.

[0047] Refer to Figures 1 - 11 , which shows a mosquito sampling attractant source anti-diffusion device provided in an embodiment of the present application, including: a first clamping member 1, a second clamping member 2, a limit adjusting member 4, an outer cover 5, and a plurality of skeleton members 3;

[0048] Both ends of the skeleton member 3 are respectively connected to the first clamping member 1 and the second clamping member 2; the first clamping member 1 is connected to the limit adjusting member 4, and the first clamping member 1 is movably arranged along the axial direction of the limit adjusting member 4; the second clamping member 2 is connected to the limit adjusting member 4; the outer cover 5 covers the plurality of skeleton members 3;

[0049] The limit adjusting member 4 limits the first clamping member 1 through a limit structure 41, so that the plurality of skeleton members 3 are maintained in a first deformation state or a second deformation state;

[0050] When the plurality of skeleton members 3 are in the first deformation state, the middle part of the plurality of skeleton members 3 expands radially along the limit adjusting member 4 to form a receiving cavity for receiving the attractant source;

[0051] When the plurality of skeleton members 3 are in the second deformation state, the middle part of the plurality of skeleton members 3 contracts radially along the limit adjusting member 4.

[0052] In the embodiments of the present application, compared with the existing gas attractant mosquito samplers which usually have poor trapping effects and are inconvenient to use, the present application provides a mosquito sampler attractant anti-diffusion device, including: a first clamping member 1, a second clamping member 2, a limit adjusting member 4, an outer cover 5 and a plurality of skeleton members 3; both ends of the skeleton member 3 are respectively connected to the first clamping member 1 and the second clamping member 2; the first clamping member 1 is connected to the limit adjusting member 4, and the first clamping member 1 is movably arranged along the axial direction of the limit adjusting member 4; the second clamping member 2 is connected to the limit adjusting member 4; the outer cover 5 covers the plurality of skeleton members 3; the limit adjusting member 4 limits the first clamping member 1 through a limit structure 41, so that the plurality of skeleton members 3 are kept in a first deformation state or a second deformation state; when the plurality of skeleton members 3 are in the first deformation state, the middle part of the plurality of skeleton members 3 extends radially along the limit adjusting member 4 to form a containing cavity for containing the attractant; when the plurality of skeleton members 3 are in the second deformation state, the middle part of the plurality of skeleton members 3 contracts radially along the limit adjusting member 4. The present application solves the technical problems of the existing gas attractant mosquito samplers with poor trapping effects and inconvenient use. The mosquito sampler attractant anti-diffusion device provided by the present application has a simple structure, is convenient to unfold and store, is convenient to carry, has a high utilization efficiency of the attractant, and improves the mosquito capture efficiency.

[0053] Next, a mosquito sampler attractant anti-diffusion device in the exemplary embodiment will be further described.

[0054] It should be noted that referring to Figure 3 , the skeleton member 3 includes but is not limited to a steel wire made of an elastic material; when the skeleton member 3 is made of an elastic material, the first deformation state can be an elastic deformation state or an elastic recovery state, and the second deformation state can correspond to an elastic recovery state or an elastic deformation state; Figures 1 - 5 Fig. shows a structural schematic diagram of a mosquito sampler attractant anti-diffusion device provided by the present application when the first deformation state is an elastic deformation state; the skeleton member 3 can also achieve equivalent deformation through a non-elastic material.

[0055] The connection between the first clamping member 1 and the limit adjusting member 4 is movable to ensure that the plurality of skeleton members 3 can be switched between the first deformation state and the second deformation state; the outer cover 5 can include a breathable cloth and a waterproof cloth, the breathable cloth can be arranged on the side close to the first clamping member 1, and the waterproof cloth can be arranged on the side close to the second clamping member 2.

[0056] As an example, the mosquito sampler attractant anti-diffusion device provided by the present application can be unfolded and folded through different deformation states of the skeleton member 3;

[0057] Reference Figures 1 - 5 When the plurality of frame members 3 are in the first deformation state, the middle part of the plurality of frame members 3 expands along the radial direction of the limit adjustment member 4 to form a receiving cavity for receiving the attractant. At this time, the plurality of frame members 3 are spherical as a whole, and the outer cover 5 is opened by the plurality of frame members 3. Since the density of the gas attractant is greater than that of the air, the attractant will fall after being released. The gas attractant can fall into the receiving cavity from the top opening of the outer cover 5 or be sucked into the receiving cavity by the fan, and be enriched at the top of the outer cover 5 to attract mosquitoes. The outer cover 5 can prevent the attractant from diffusing and losing.

[0058] Reference Figures 10 - 11 When the plurality of frame members 3 are in the second deformation state, the middle parts of the plurality of frame members 3 are contracted along the radial direction of the limit adjustment member 4. At this time, the plurality of frame members 3 are columnar as a whole, and the volume of the contracted accommodating cavity is significantly reduced, which is convenient for storage and carrying;

[0059] It should be noted that the “middle” of the plurality of frame members 3 is a relative concept relative to the “two ends” of the frame members 3 and should not be interpreted as just the center of the geometric shape. Those skilled in the art may adjust the shape of the frame members 3 according to actual conditions.

[0060] Reference Figure 3 In one embodiment of the present application, the first deformation state is an elastic deformation state;

[0061] When the plurality of frame members 3 are in the first deformation state, the limiting structure 41 of the limiting adjustment member 4 is disposed on a side of the first clamping member 1 away from the second clamping member 2 .

[0062] It should be noted that the second deformation state may be an elastic recovery state; when the first deformation state is switched to the second deformation state, the limiting structure 41 of the limiting adjustment member 4 is released from limiting the first clamping member 1, so that the plurality of framework members 3 drive the first clamping member 1 to move along the axial direction of the limiting adjustment member 4 when they are elastically restored, thereby finally reaching the second deformation state;

[0063] When switching from the second deformation state to the first deformation state, the plurality of frame members 3 undergo elastic deformation, and the limiting structure 41 of the limiting adjustment member 4 is arranged on the side of the first clamping member 1 away from the second clamping member 2, thereby limiting the first clamping member 1, thereby preventing the plurality of frame members 3 from elastically recovering.

[0064] As an example, the elastic state of the skeleton member 3 can be set according to actual requirements. If the first deformation state is an elastic recovery state and the second deformation state is an elastic deformation state, when the plurality of skeleton members 3 are in the first deformation state, the limiting structure 41 of the limiting and adjusting member 4 can be arranged on the side of the first clamping member 1 close to the second clamping member 2.

[0065] Refer to Figure 5 and Figure 9 In an embodiment of the present application, the limiting and adjusting member 4 includes at least two limiting columns 42 whose one ends are bent and connected, and the other ends of the limiting columns 42 are sequentially inserted through the first clamping member 1 and the second clamping member 2.

[0066] It should be noted that the bent and connected end of the limiting column 42 can be used as a handle for convenient carrying; the at least two limiting columns 42 can ensure the stability of the first clamping member 1 during movement and the strength of the limiting structure 41 of the limiting column 42.

[0067] Refer to Figures 7 - 8 In an embodiment of the present application, the first clamping member 1 is provided with a slot hole 11, and a stepped structure 12 is provided at one end of the slot hole 11;

[0068] When the first clamping member 1 is limited by the limiting structure 41 of the limiting and adjusting member 4, the limiting structure 41 of the limiting and adjusting member 4 is arranged at one end of the slot hole 11, and the limiting structure 41 of the limiting and adjusting member 4 cooperates with the stepped structure 12 of the first clamping member 1;

[0069] When the limiting structure 41 of the limiting and adjusting member 4 is disengaged from limiting the first clamping member 1, the limiting structure 41 of the limiting and adjusting member 4 is arranged at the other end of the slot hole 11, and the limiting structure 41 of the limiting and adjusting member 4 is disengaged from cooperating with the stepped structure 12 of the first clamping member 1.

[0070] It should be noted that one end of the slot hole 11 is used for limiting, and the other end of the slot hole 11 is used for disengaging from limiting. During use, only the limiting structure 41 of the limiting and adjusting member 4 needs to be snapped into the corresponding end, which is convenient for the deployment or folding of the mosquito sampling device's attractant anti-diffusion device.

[0071] Refer to Figures 7 - 8 In an embodiment of the present application, a convex portion 13 is provided in the middle of the slot hole 11;

[0072] When the first clamping member 1 is limited by the limiting structure 41 of the limiting and adjusting member 4, the convex portion 13 limits the limiting structure 41 of the limiting and adjusting member 4 along the length direction of the slot hole 11.

[0073] It should be noted that the protruding portion 13 can prevent the limiting and adjusting member 4 from being disengaged due to accidental slippage.

[0074] Referring to Figures 1 - 2 , in an embodiment of the present application, the limiting and adjusting member 4 is provided with an attractant release device 6, the first clamping member 1 is provided with a collection fan, and a ventilation hole 51 is provided on one side of the outer cover 5 close to the first clamping member 1.

[0075] It should be noted that the attractant release device 6 is arranged on the limiting and adjusting member 4 to ensure that the attractant can effectively fall into the accommodation cavity formed by the plurality of skeleton members 3; the collection fan is arranged on the first clamping member 1 to ensure that the attracted mosquitoes can be effectively inhaled in the enrichment area of the attractant. The collection fan can be used to suck the mosquitoes into a specific collection container to achieve mosquito capture. The structures of the collection fan and the collection container are not limited in the present application; the collection fan can also suck the attractant into the accommodation cavity to promote the enrichment of the attractant; the ventilation hole 51 is arranged on one side of the outer cover 5 close to the first clamping member 1, so that the attractant in the accommodation cavity can overflow through the ventilation hole 51, so as to increase the concentration of the attractant on the surface of the outer cover 5 and improve the capture efficiency, and at the same time, prevent the excessive loss of the attractant; the ventilation hole 51 should be understood as a structure designed to allow the attractant gas to pass through. Figure 1 The holes shown in

[0076] are only for illustrative purposes to facilitate understanding and should not be construed as a limitation on the size of the ventilation hole 51; at the same time, it should be understood that the above are only preferred embodiments and should not be construed as the only limitation on the installation or setting positions of the attractant release device 6, the collection fan and the ventilation hole 51.

[0077] , in an embodiment of the present application, it further includes: a support member 7;

[0078] One end of the support member 7 is hinged to the second clamping member 2;

[0079] When the plurality of skeleton members 3 are in the first deformation state, the support member 7 is fixedly arranged on the side of the second clamping member 2 away from the first clamping member 1;

[0080] When the plurality of skeleton members 3 are in the second deformation state, the other end of the support member 7 is arranged close to the first clamping member 1. Figure 4 and Figure 9, the support member 7 may include a bent member 71 and a straight rod 72. One folded surface of the bent member 71 is fixed to the second clamping member 2, and the other folded surface of the bent member 71 is hinged to the straight rod 72, and the tightness can be adjusted by screws; the support member 7 may include at least three straight rods 72. When the required height is relatively low, the at least three straight rods 72 may be overlapped; Refer to Figures 10 - 11 , when the plurality of skeleton members 3 are in the second deformation state, the support member 7 may be arranged parallel to the axial direction of the limit adjustment member 4 to further reduce the folding and storage volume of the mosquito sampling device's attracting source anti-diffusion device.

[0081] In an embodiment of the present application, a first circular ring member 14 is provided on the side wall of the first clamping member 1, and one end of the skeleton member 3 is hinged to the first circular ring member 14.

[0082] It should be noted that the first circular ring member 14 and the hinge structure facilitate the deformation and restoration of the skeleton member 3; a second circular ring member 21 may also be provided on the side wall of the second clamping member 2, and the other end of the skeleton member 3 is hinged to the second circular ring member 21. The functions, uses, and corresponding structures of the second circular ring member 21 can be correspondingly referred to the description of the first circular ring member 14.

[0083] Refer to Figures 6 - 7 , in an embodiment of the present application, one end of the skeleton member 3 is a hook-shaped structure, and the first circular ring member 14 is inserted through the hook-shaped structure of the skeleton member 3;

[0084] A guide groove 15 is provided on the side wall of the first clamping member 1, and the guide groove 15 is used to limit the hook-shaped structure of the skeleton member 3 along the circumferential direction of the first circular ring member 14.

[0085] It should be noted that to prevent the first circular ring member 14 from detaching from the hinge with the skeleton member 3, the opening width of the hook-shaped structure of the skeleton member 3 should be smaller than the thickness of the first circular ring member 14, or be set as a closed-loop structure with a closed opening; the guide groove 15 can be arranged parallel to the axial direction of the limit adjustment member 4 to stabilize the deformation direction of the skeleton member 3.

[0086] Refer to Figures 7 - 8 , in an embodiment of the present application, a ring groove 16 is provided on the side wall of the first clamping member 1, and the ring groove 16 is used to accommodate the first circular ring member 14;

[0087] The first circular ring member 14 is a semi-closed structure with both ends bent, and the bent portion of the first circular ring member 14 is inserted through the opening on one side of the ring groove 16.

[0088] It should be noted that the opening on one side of the annular groove 16 can, on the one hand, limit the first annular member 14, and on the other hand, facilitate the installation of the first annular member 14.

[0089] In a specific implementation, to save production costs, some structures in the embodiments of the present application can use the same parts. For example: the several skeleton members 3 can use the same parts; the first clamping member 1 and the second clamping member 2 can use the same parts; the first annular member 14 and the second annular member 21 can use the same parts; the support member 7 can include several identical parts.
