The top of the box body 1 is covered with a box cover 6, the box cover 6 is provided with a handle 7, the box cover 6 is connected with the box body 1 through threads, and after the box cover 6 covers the box body 1, a seal is formed in the box body 1, so that the smell in the box body 1 is prevented from leaking in the transportation and storage processes, the smell concentration in the box body 1 is ensured, and the effective performance of sniffing training is ensured; handle 7 on case lid 6 makes things convenient for the standard dog teacher to remove training equipment.
The bottom of the box body 1 is provided with a positioning component 8 for fixing the position of the box body 1, when the box body 1 is required to be fixed on an iron object, the positioning component 8 adopts a neodymium iron boron strong magnet with strong magnetism, so that equipment can be adsorbed on the iron object, such as a frame chassis, a guardrail, a street lamp pole and the like, for fixing; when the positioning component 8 needs to be placed on soft soil, the positioning component is an inverted cone-shaped rod piece and is fixed by adopting a method of nailing into the soil; when the training equipment needs to be placed on hard ground, the positioning assembly 8 adopts a large and heavy iron plate, and the training equipment is effectively placed on the ground.
The baffle plate 1-1 is provided with the ejection reward device 9, when the dog searches for the target, the ejection reward device 9 is used for rewarding the dog with reward articles, and the training enthusiasm of the dog is increased.
The ejection reward device 9 comprises an ejection cavity 9-1, a spring I9-2 and a locking block 9-3, the spring I9-2 is arranged in the ejection cavity 9-1, an ejection switch component used for clamping the spring I9-2 is arranged on the ejection cavity 9-1, a dog trainer places reward articles (such as tennis balls and toys) on the spring and downwards compresses the spring to enable the ejection switch component to buckle the spring, when the ejection switch component is loosened, the spring upwards bounces to eject the reward articles and give rewards to the dog in time, the dog can establish a habit of actively sniffing the equipment through attention to the toy, the habit is not manually forced to sniff passively in a traditional mode, and a good foundation is laid for subsequent conditional reflex.
The ejection switch assembly comprises an electric telescopic rod 9-6, a locking block 9-3 and a spring II 9-5, wherein the electric telescopic rod 9-6 is fixedly arranged on the partition plate 1-1, a telescopic sleeve 9-4 is arranged on a telescopic rod of the electric telescopic rod 9-6, the locking block 9-3 is arranged in the telescopic sleeve 9-4, the free end of the locking block 9-3 extends into the ejection cavity 9-1, and the spring II 9-5 is arranged at the bottom of the locking block 9-3; the electric telescopic rod 9-6 is connected with a signal output end of the controller 4, the upper surface of one end, extending into the ejection cavity 9-1, of the locking block 9-3 is an inclined surface, when the spring I9-2 is pressed down, the locking block 9-3 is forced to move leftwards, the spring I9-2 is conveniently pressed down, after the spring I9-2 is compressed to a specified position, the locking block 9-3 is bounced rightwards by the spring II 9-5, the main spring I9-2 is clamped, and when the electric telescopic rod 9-6 is shortened, the locking block 9-3 is pulled to move leftwards, the locking block 9-3 is pulled open, the spring is bounced, the rewarded objects can be given to the dog through remote control of the controller 4, and timely rewards the dog.
1 bottom of box be equipped with audio amplifier 10, audio amplifier 10 is connected with controller 4, when carrying out the appointed article of a plurality of training casees and sniffing the training in-process, 4 remote control audible system of accessible controller make a sound, interfere with sniffing of dog, the special attention of training dog when sniffing.
All openings and corners of box 1 all adopt the circular arc transition, effectively prevent that training equipment's sharp-pointed edge from causing the injury to the dog, guarantee that the dog sniffs the safety of training and go on.
The working process of the invention is as follows: before sniffing training, the partition plate 1-1 is taken down, sniffing articles are placed in the air source cavity 1-3, then the partition plate 1-1 is placed to isolate the air source cavity 1-3 (the partition plate 1-1 with through holes is adopted in the initial training stage, and the partition plate 1-1 without through holes is adopted in the later training stage), the box cover 6 is covered to transport the box body 1 to a training site, and the positioning assembly 8 is utilized to fix the box body 1.
When sniffing the training initial stage, place box 1 on open subaerial, open case lid 6, command dog sniffs the training, when the dog sniffed box 1 position, shortened through remote controller 5 control electric telescopic handle 9-6, popped out reward article, rewarded the dog, practise repeatedly.
Sniffing when training later stage, place box 1 in comparatively secret position (like frame chassis), open case lid 6, air pump 2 is rotatory takes out the gas of air supply intracavity, introduce into through gas passage 1-5 and sniff the chamber and distribute out, then the commander dog is sniffed, sniffing the in-process, if discovering the dog sniffing the direction deviation great, accelerate the rotation through remote controller 5 control air pump 2, make box 1 give off the smell more obvious, and guide in addition artifically, make the dog resume correctly sniffing the direction.
When a plurality of training boxes appointed article sniffing training, accessible controller 4 remote control sound makes a sound, disturbs the sniffing of dog.
The air pump is adopted to pump the air containing the smell to be sniffed, then the air is discharged into the air to form a weak smell source, the dog is sniffed and trained, and the concentration of the smell to be sniffed in the air is changed by changing the air discharge speed of the air pump, so that the difficulty of the sniffing training of the dog is changed, and the sniffing capability of the dog is gradually improved.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, while the invention has been described in detail with reference to the foregoing preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims; the size of the attached figure is irrelevant to the specific real object, and the size of the real object can be changed at will.
