Description

Technical Field

[0001] The utility model relates to the technical field of tobacco pest control, in particular to a dustproof protection device for a tobacco insect trap. Background Art

[0002] In the silk-making workshop, two production lines occupy approximately 17,000 square meters and are equipped with 104 pest monitoring points. The cigar workshop has 70 monitoring points, for a total of 174. The large number and widespread distribution of tobacco insect monitoring points make tobacco insect traps a crucial component of this monitoring. Currently, tobacco insect traps are open and unprotected, leaving them exposed to dust during routine maintenance. This results in large amounts of tobacco ash and soot clinging to the trap surface, compromising the accuracy and effectiveness of the trapping process.

[0003] In the prior art, dust covers are often used to prevent tobacco ash and smoke from adhering to the trap. For example, patent publication number CN216651051U discloses a novel tobacco beetle trap comprising a base, a trapping plate, and a dust cover. The trapping plate is mounted on the base. The trapping plate comprises a bottom plate with an adhesive film on its surface, on which bait for catching tobacco beetles is placed, and a top plate disposed above the bottom plate. The dust cover is movably connected to the base. Tobacco beetles enter the trap through the wall. Another example is patent publication number CN215012899U, which discloses a dust-proof device for a tobacco beetle trap. The device comprises a box structure with an opening formed by a left baffle, a right baffle, a bottom plate, and a top plate secured to a rear baffle. The box structure is provided with a through hole to facilitate entry of tobacco beetles, and the box structure is covered by a front baffle, thereby securing the tobacco beetle trap within the box structure and protecting it from dust.

[0004] It can be seen that in the prior art, most of the dust covers are set on the front to prevent dust, and through holes are set on the sides and / or the back for tobacco insects to enter. However, in fact, dust can also enter the through holes on the sides and / or the back, and the dust prevention effect is insufficient. Utility Model Content

DETAILED DESCRIPTION

[0026] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0027] A dust protection device for a tobacco insect trap, such as Figure 1 、2 As shown in Figure 4, first, it includes an outer shell 1. The shape of the outer shell 1 is not limited, as long as the outer shell 1 is a structure with the surface being completely closed except for the external opening 111 that is set later, and the interior being hollow. The outer shell 1 is used to install the entire device in a silk-making workshop, and is usually fixed on the inner wall of the workshop. Therefore, in some embodiments, the outer shell 1 includes a fixed back panel 1a for being fixedly connected to the wall by screws or the like. In order to achieve a closed effect, the outer shell 1 also includes a panel 1b opposite to the fixed back panel 1a, and a side panel 1c for connecting the side edge of the fixed back panel 1a and the side edge of the panel 1b. Based on the different shapes of the fixed back panel 1a and the panel 1b, the number of side panels 1c is different. In some embodiments, the fixed back panel 1a and the panel 1b are both rectangular, so four side panels 1c are provided; at the same time, as shown in Figure 4, the outer shell 1 includes a fixed back panel 1a. Figure 1 As shown, the side panels 1c are fixedly connected to the fixed back panel 1a, the left end of the panel 1b is hinged to the left side panel 1c, and the upper end, lower end, and right end of the panel 1b are respectively abutted against the corresponding side panels 1c to achieve the sealing effect of the housing 1. In some embodiments, the upper end, lower end, and right end of the panel 1b are respectively magnetically connected to the corresponding side panels 1c to improve the sealing effect.

[0028] In order to facilitate the entry of tobacco insects, the housing 1 includes at least one inlet surface 11 with an external opening 111. The position of the inlet surface 11 is not limited, but it is not recommended to be placed on the upper side plate 1c of the housing 1 where dust easily accumulates. In some embodiments, such as Figure 1 As shown, it can be set on the panel 1b to face the silk-making workshop to improve the efficiency of tobacco insects entering. Figure 2 As shown, it can also be set on the left and right side panels 1c to reduce the entry of dust.

[0029] The present application also includes an inner shell 2 disposed in the outer shell 1. The shape of the inner shell 2 is also not limited, and it can be a structure with a surface that is completely closed except for the inner opening 221 that is subsequently disposed, and a hollow interior. The inner shell 2 is used to stop dust entering from the outer opening 111, but it is not limited to blocking smoke insects. Therefore, the inner shell 2 includes a dust receiving surface 21 corresponding to the inlet surface 11 of the outer shell 1, and at least one trapping surface 22 provided with the inner opening 221. The dust receiving surface 21 is provided with a dust adsorption layer, and the trapping surface 22 is not on the same plane as the dust receiving surface 21. Specifically, the inner shell 2 includes an inner back plate corresponding to the fixed back plate 1a of the outer shell 1, an inner panel corresponding to the panel 1b of the outer shell 1, and four inner side panels corresponding to the four side panels 1c of the outer shell 1. When the outer opening 111 is disposed on the outer shell panel 1b, the side of the inner panel close to the panel 1b becomes the dust receiving surface, and the four inner side panels and the inner back plate can all serve as the trapping surface 22; in some embodiments, such as Figure 1As shown, the inner back plate is used to fix the inner shell 2 in the outer shell 1, and the left and right inner plates are provided with inner openings 221 as the trapping surfaces 22. When the outer openings 111 are provided on the left and right side plates 1c of the outer shell, the left and right inner plates are provided with ash contact surfaces respectively, and the inner panel, inner back plate, upper and lower inner plates can all serve as the trapping surfaces 22; in some embodiments, as Figure 2 As shown, the upper inner plate is provided with an inner opening 221 as the trapping surface 22, and the lower inner plate abuts against the inner bottom of the shell 1.

[0030] A tobacco insect trap is mounted within the inner shell 2. The trap includes a trapping portion that emits light or scent to attract tobacco insects, and an adhesive portion for adhering to the attracted tobacco insects. During use, tobacco insects enter between the outer shell 1 and the inner shell 2 through the outer opening 111 of the outer shell 1, then enter the inner shell 2 through the inner opening 221 of the inner shell 2, ultimately adhering to the adhesive portion of the tobacco insect trap. Due to the unavoidable presence of dust in a silk-making workshop, particularly during maintenance operations, dust also enters through the outer opening 111 of the outer shell 1. Unlike tobacco insects, dust is less likely to change direction. Therefore, most dust directly adheres to the dust adsorption layer on the dust-receiving surface 21 corresponding to the outer opening 111, unable to deflect to the trapping surface 22 in the opposite direction and enter the inner shell 2, contaminating the tobacco insect trap. This effectively prevents the tobacco insect trap from dust.

[0031] In some embodiments, in order to completely absorb the dust entering from the external opening 111 as much as possible, Figure 2 As shown, the dust receiving surface 21 includes a receiving portion corresponding to the external opening 111. The dust receiving surface 21 is a concave arc surface with the receiving portion recessed toward the interior of the inner shell 2. The concave arc surface not only increases the dust receiving area, but also ensures that dust in the receiving portion diffuses toward the external opening 111 along the concave arc surface, making it less likely to enter the space between the trapping surface 22 and the outer shell 1.

[0032] In some embodiments, in order to further prevent dust from entering the inner opening 221, as shown in FIG. Figure 1 and Figure 2 As shown, a secondary protective surface 23 is provided at the end of the dust receiving surface 21 close to the trapping surface 22. The provision of the secondary protective surface 23 increases the distance that dust needs to bypass the dust receiving surface 21 to approach the trapping surface 22. Preferably, the secondary protective surface 23 includes a connecting end connected to the dust receiving surface 21 and an opposite free end, and the free end is inclined relative to the connecting end in a direction close to the introduction surface 11. In some embodiments, as Figure 1 As shown, the secondary protection surface 23 can be a plane parallel to the trapping surface 22. In other embodiments, as shown in FIG. Figure 3 As shown, the secondary protection surface 23 is a curved surface continuous with the concave arc-shaped contact surface 21. The setting method of the inner shell 2 with the concave arc surface and the arc-shaped secondary protection surface 23 can be referred to Figure 3 The inner shell 2 includes an arc plate 2a and a connecting plate 2b, which are detachably connected via a magnetic structure. The connecting plate 2b is connected to the convex surface of the arc plate 2a. The concave surface of the arc plate 2a is provided with an ash contact surface 21, and the connecting plate 2b is provided with a trapping surface 22. The arc plate 2a can be the half of a hollow cylinder cut along the axial plane, or it can be the half of a hollow sphere. At the same time, when this inner shell 2 is installed in the outer shell 1, a connecting rod needs to be provided between the connecting plate 2b of the inner shell 2 without the trapping surface 22 and the outer shell 1. With this design, the adhesive portion of the tobacco insect trap can be provided on the convex surface of the arc plate 2a, increasing the adhesive surface area.

[0033] In addition, the dustproof effect of the present application is also related to the dust adsorption layer. The better the dust adsorption layer is at adsorbing and fixing the dust, the better the dustproof effect is. Figure 4 As shown, the dust adsorption layer includes adsorbent cotton 211 detachably connected to the dust receiving surface 21. Furthermore, in some embodiments, the dust adsorption layer further includes a friction block 212 abutting the adsorbent cotton 211 and a friction drive member that drives the friction block 212 on the adsorbent cotton 211. The friction can cause the adsorbent cotton 211 to generate static electricity, thereby improving the dust adsorption effect. Specifically, when the dust receiving surface 21 is formed by the concave surface of a hollow hemisphere, the friction block 212 can be designed as an arc-shaped strip.

[0034] The structure of the friction drive member is not limited. In some embodiments, Figure 5 As shown, the introduction surface 11 is provided with an insertion hole, and the friction drive member includes an insertion tube 24 that can be slidably arranged in the insertion hole along the axial direction of the insertion hole. The insertion tube 24 includes a passive portion located within the outer shell 1 and a driving portion located outside the outer shell 1. The passive portion is provided with a passive rotating shaft 241, which is connected to the center of the friction block 212 by a connecting rod. The passive portion is provided with an arc opening for the connecting rod to pass through. The driving portion is provided with a driving rotating shaft 242, which is connected to the passive rotating shaft 241 by a gear and tooth chain transmission structure. The driving portion is provided with a knob for controlling the rotation of the driving rotating shaft 242. When friction is not required, the driving rotating shaft 242 is controlled by the knob to drive the passive rotating shaft 241 to rotate until the friction block 212 is parallel to the vertical plane. Then, the insertion tube 24 is slid away from the inner shell 2 so that the friction block 212 is received and abutted against the inner wall of the outer shell 1. When friction is required, the driving shaft 242 is controlled by the knob to drive the passive shaft 241 to rotate until the friction block 212 is parallel to the horizontal plane, and then the tube 24 is slid toward the inner shell 2 so that the friction block 212 abuts against the adsorption cotton 211, and then the driving shaft 242 is controlled by the knob to drive the passive shaft 241 to rotate, so that the friction block 212 rotates and rubs on the adsorption cotton 211.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
