Abstract
Description
Technical Field
[0001] This utility model relates to the field of olfactory source trainer technology, specifically to a olfactory source trainer for drug-sniffing dogs. Background Technology
[0002] Drug detection dog scent training is a professional training program for dogs designed to enable them to use their keen sense of smell to identify and track the scent of drugs, playing an important role in drug detection work.
[0003] Existing technologies lack a structure for fixing the olfactory sample in a fixed position to prevent rapid evaporation. This means that most existing olfactory training devices rely on simple test strips as odor carriers. Since the odor on the test strips evaporates quickly, they become ineffective after use. In actual training, police dogs often cannot accurately capture the odor in one go, forcing trainers to repeatedly replace the test strips to re-collect the sample. This not only increases the complexity of training but also significantly slows down the training progress and reduces overall efficiency. If a large amount of drug olfactory source is used at once, it is easy to fall or be missed during placement due to the complex environment or to evaporate quickly due to exposure to air. Based on the shortcomings of existing technologies, this utility model designs a drug-sniffing dog olfactory training device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a drug-sniffing dog olfactory source trainer, which has the advantages of fixed posture adjustment of olfactory source samples to prevent rapid volatilization.
[0005] This utility model provides the following technical solution: a drug-sniffing dog scent source trainer, including a spherical lower shell, a counterweight is provided inside the spherical lower shell, a scent source storage groove is provided on the upper surface of the counterweight, and a stabilizing mechanism is provided between the spherical lower shell and the counterweight to ensure that the scent source storage groove always faces upward.
[0006] The stabilizing mechanism includes a first stabilizing frame, a first stabilizing shaft, a second stabilizing frame, a second stabilizing shaft, a third stabilizing shaft, and a connecting shaft. The first stabilizing frame is rotatably disposed inside the spherical lower housing. The first stabilizing shaft is disposed at the upper and lower ends of the first stabilizing frame. The second stabilizing frame is rotatably connected to the upper and lower first stabilizing shafts. The second stabilizing shaft is rotatably disposed on both sides of the second stabilizing frame. The third stabilizing shaft is disposed on both sides of the first stabilizing frame. The connecting shaft is rotatably connected to the outer end of the third stabilizing shaft.
[0007] As a preferred technical solution of this utility model, a spherical upper shell is provided on the top of the spherical lower shell, and odor diffusion holes are provided through the spherical lower shell and the spherical upper shell. A connecting groove is provided at the inner wall edge of the spherical lower shell and the spherical upper shell, and a fixing block is fixedly connected at the inner wall edge of the spherical lower shell and the spherical upper shell. A magnet is fixedly connected inside the fixing block.
[0008] As a preferred embodiment of this utility model, the top of the counterweight is covered with a perforated cover plate, and a buckle is fixedly connected to the bottom edge of the perforated cover plate.
[0009] As a preferred embodiment of this utility model, the second stabilizer is rotatably connected inside the first stabilizer, and the inner end of the second stabilizer shaft is fixedly connected to the counterweight.
[0010] As a preferred embodiment of this utility model, the third stabilizing shaft and the connecting shaft are rotatably mounted on the connecting groove.

[0013] In a preferred embodiment of this invention, the counterweight is rotatably disposed inside the first and second stabilizers.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This drug-sniffing dog scent trainer, after the scent source is safely placed on the counterweight, places the spherical lower and upper shells containing the scent source directly into a complex simulated environment. During placement or removal, if the spherical lower and upper shells rotate, the first stabilizing frame will rotate using the third stabilizing shaft and connecting shaft under the counterweight, ensuring that the internal posture of the first stabilizing frame within the spherical lower and upper shells does not change significantly and that the opening of the scent source storage slot remains upward. When the spherical lower and upper shells rotate at other angles, the first and second stabilizing frames will rotate around the first, second, and third stabilizing shafts under the counterweight, ensuring that the top opening of the scent source storage slot always faces upward, thus preventing the scent source from falling out and effectively controlling the evaporation rate and concentration of the scent source.

[0022] 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.
[0023] Please see Figure 1-5A drug-sniffing dog scent trainer includes a spherical lower shell 1, inside which is a counterweight 2. A scent storage slot 201 is formed on the upper surface of the counterweight 2. A stabilizing mechanism 3 is provided between the spherical lower shell 1 and the counterweight 2 to ensure the scent storage slot 201 always faces upwards. A spherical upper shell 101 covers the top of the spherical lower shell 1. Scent diffusion holes 102 are formed through both the spherical lower shell 1 and the spherical upper shell 101. A connecting groove 103 is provided at the inner wall edge of the lower outer shell 1 and the spherical upper outer shell 101. A fixing block 104 is fixedly connected at the inner wall edge of the spherical lower outer shell 1 and the spherical upper outer shell 101. A magnet 105 is fixedly connected inside the fixing block 104. The connecting groove 103 provided on the spherical upper outer shell 101 and the connecting groove 103 provided on the spherical lower outer shell 1 are engaged with each other. The magnet 105 provided on the spherical upper outer shell 101 and the magnet 105 provided on the spherical lower outer shell 1 are engaged with each other.
[0024] By setting a fixing block 104 and a magnet 105, the spherical lower outer shell 1 and the spherical upper outer shell 101 can be quickly separated or closed. By setting a connecting groove 103, the stabilizing mechanism 3 can be rotated and limited.
[0025] Please see Figure 4-5 The stabilizing mechanism 3 includes a first stabilizing frame 301, a first stabilizing shaft 302, a second stabilizing frame 303, a second stabilizing shaft 304, a third stabilizing shaft 305, and a connecting shaft 306. The first stabilizing frame 301 is rotatably disposed inside the spherical lower outer shell 1. The first stabilizing shaft 302 is disposed at the upper and lower ends of the first stabilizing frame 301. The second stabilizing frame 303 is rotatably connected to the upper and lower first stabilizing shafts 302. The second stabilizing shaft 304 is rotatably disposed through both sides of the second stabilizing frame 303. The third stabilizing shaft 305 is disposed on both sides of the first stabilizing frame 301. The connecting shaft 306 is rotatably connected to the outer end of the third stabilizing shaft 305. The second stabilizing frame 303 is rotatably connected inside the first stabilizing frame 301. The inner end of the second stabilizing shaft 304 is fixedly connected to the counterweight 2. The third stabilizing shaft 305 and the connecting shaft 306 are rotatably disposed on the connecting groove 103.
[0026] By setting a first stabilizing frame 301, a second stabilizing rotating shaft 304, a third stabilizing rotating shaft 305, and a connecting shaft 306, and by connecting the second stabilizing rotating shaft 304 to the counterweight 2, longitudinal rotational swing adjustment can be achieved with the assistance of the counterweight 2. By setting a first stabilizing rotating shaft 302 and a second stabilizing frame 303, the counterweight 2 can be adjusted laterally by rotational swing.
[0027] Please see Figure 5The top of the counterweight 2 is covered with a perforated cover plate 202, and a buckle 203 is fixedly connected to the bottom edge of the perforated cover plate 202. The buckle 203 is snapped onto the inner edge of the top of the odor source storage slot 201. The perforated cover plate 202 is closed on the top of the odor source storage slot 201. The counterweight 2 is rotatably disposed inside the first stabilizer 301 and the second stabilizer 303.
[0028] Working principle: When the drug-sniffing dog scent trainer is used, in the initial state, the inner walls of both the spherical lower shell 1 and the spherical upper shell 101 are provided with fixing blocks 104 filled with magnets 105. The spherical lower shell 1 and the spherical upper shell 101 are magnetically closed by the magnets 105 to control the volatilization of the scent source and prevent the scent source from falling and being lost. The first stabilizing frame 301 and the second stabilizing frame 303, which are rotatably connected inside the spherical lower shell 1 and the spherical upper shell 101, are connected by the third stabilizing shaft 305 and the connecting shaft 306. The counterweight 2 is rotatably connected inside the first stabilizing frame 301 and the second stabilizing frame 303 through the second stabilizing shaft 304 to place the scent source and to ensure that the opening of the scent source storage slot 201 in the counterweight 2 always faces upward.
[0029] When it is necessary to quickly place the odor source and ensure that the opening of the counterweight 2 always faces upwards, after the odor source is safely placed on the counterweight 2, the spherical lower shell 1 and spherical upper shell 101 containing the odor source are directly placed into the complex simulation environment. If the spherical lower shell 1 and spherical upper shell 101 rotate during placement or removal, the first stabilizing frame 301 will rotate using the third stabilizing shaft 305 and the connecting shaft 306 under the counterweight 2, thus adjusting the internal posture of the first stabilizing frame 301 within the spherical lower shell 1 and spherical upper shell 101. Without significant changes and with the opening of the odor source storage tank 201 still facing upwards, when the spherical lower outer shell 1 and the spherical upper outer shell 101 rotate at other angles, the first stabilizer 301 and the second stabilizer 303 will rotate around the first stabilizer shaft 302, the second stabilizer shaft 304 and the third stabilizer shaft 305 under the counterweight of the counterweight block 2, so that the top opening of the odor source storage tank 201 always faces upwards, thereby preventing the odor source in the odor source storage tank 201 from falling out and effectively controlling the evaporation rate and concentration of the odor source.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
