Description

Technical Field

[0001] The utility model relates to the technical field of dog olfactory testing, in particular to auxiliary equipment for dog olfactory sensitivity testing. Background Art

[0002] Dogs have a very keen sense of smell, but different dog breeds have different olfactory sensitivities. Dog work is based on smell, and evaluating a dog's sense of smell can identify a dog's working ability. Therefore, a testing device is needed to test the dog's olfactory sensitivity using the dog's sensitivity to smell.

[0003] The Chinese patent with authorization announcement number CN210408391U discloses a dog olfactory testing device, comprising an outer cover, an olfactory source gas distribution chamber, a food box, a food box holder, a sliding food box rack, and a general bracket. The inner wall of the outer cover is provided with a clip and a first slot. The general bracket comprises a bottom plate and a column provided with a slide rail. The olfactory source gas distribution chamber is provided below the upper opening of the outer cover. The bottom of the olfactory source gas distribution chamber is provided with an opening and is close to the opening of the food box. A food box holder and a sliding food box rack are provided below the food box. The food box holder is provided with a tray and a second slot. The sliding food box rack is provided with a cover plate, a horizontal spring telescopic rod fixed to the column, and a flat plate with a supporting hole. The first slot and the second slot are buckled with the column and can slide up and down. After the dog smells the smell, it picks and grabs the outer cover, and the first slot and the second slot slide downward along the column. When the tray moves down to the food box and touches the flat plate, it is separated from the food box. The spring telescopic rod is released to drive the food box on the flat plate to slide out from one side of the outer cover. The utility model can simply and effectively test the dog's sense of smell.

A partition assembly is arranged in the storage box 5 to divide the inner groove of the storage box 5 into a plurality of placement grooves. The partition assembly includes a rotating shaft 501 and a partition 502. A non-cylindrical slot is arranged on the rotating shaft 501. The partition 502 is connected to the rotating shaft 501 and is distributed in a ring array around the axis of the rotating shaft 501. The rotating shaft 501 and the partition 502 are both slidably connected to the bottom plate of the storage box 5 and the bottom surface of the partition A2. A plurality of air holes are arranged at the bottom of the storage box 5, each of which is connected to the corresponding placement groove, and a filter 503 is arranged in the air hole. The upper and lower ends of the filter 503 are respectively flush with the upper and lower surfaces of the bottom plate of the storage box 5. The bottom plate of the storage box 5 is slidably connected to the bottom plate of the box body 1, and a handle 504 is arranged on the outer baffle of the storage box 5. A through hole 201 is arranged on the partition A2. The suction hood A7 is connected to the box body 1, and the air inlet end of the suction hood A7 is provided with a switch A. The suction hood B12 is connected to the box body 1 and communicated with the output end of the odor concentration regulating chamber 103. The air inlet end of the suction hood B12 is provided with a switch B, and the switch A and the switch B are both valves 15. A connecting pipe B11 connected to the output end of the odor concentration regulating chamber 103 is provided on the top cover 8, and the connecting pipe B11 is connected to the suction hood B12. The input end of the fan 13 and the pipe mouth of the one-way air inlet pipe 4 are only connected to one of the placement slots, and the output end of the fan 13 is connected to the suction hood A7 and the input end of the odor concentration regulating chamber 103. The output end of the fan 13 is connected to the connecting pipe C14, one end of the connecting pipe C14 is connected to the connecting pipe A6 and the other end is connected to the input end of the odor concentration regulating chamber 103. The driving component is connected to the partition A2 and drives the partition component to rotate in the inner groove of the storage box 5, so that the fan 13 draws air sources from different placement slots. The driving assembly includes a hollow shaft 16, a gear, a motor 17, a pin 18 and a hydraulic cylinder 20. The hollow shaft 16 passes through the partition A2 and is rotatably connected thereto, the motor 17 is connected to the partition A2, and gears are provided on the output end of the motor 17 and the hollow shaft 16, and the two gears are meshed and connected. The pin 18 passes through the hollow shaft 16 and is slidably connected thereto, and the cross section of the pin 18 is the same as the shape and size of the slot, and the pin 18 is inserted into the slot and is slidably connected thereto in the vertical direction.The top end of the pin rod 18 is rotatably connected to the support plate 19, and the hydraulic cylinder 20 is connected to the partition A2 and drives the support plate 19 and the pin rod 18 to rise and fall.

[0023] In this embodiment, the device is connected to a power source, and the hydraulic cylinder 20 is started. The hydraulic cylinder 20 pushes up the support plate 19 and the pin rod 18 until the pin rod 18 is pulled out of the rotating shaft 501, and then the storage box 5 is pulled out, and different objects to be tested are placed in each placement slot, and then the storage box 5 is pushed back into the box body 1, and the hydraulic cylinder 20 is started to pull down the support plate 19 and the pin rod 18 until the pin rod 18 is reinserted into the rotating shaft 501. The fan 13 is started, the valve 15 of the suction hood A7 is opened, and the valve 15 of the suction hood B12 is closed. The fan 13 extracts the smell of the object to be detected at the current position from the placement slot and sends it to the suction hood A7. The dog obtains the smell information of the current object to be detected through the sense of smell. Then the motor 17 drives the shaft 501 and the partition 502 to rotate, and another object to be detected is switched to the current placement slot. The valve of the suction hood A7 is closed, and the valve 15 of the suction hood B12 is opened. The fan 13 extracts the smell from the current placement slot and sends it to the smell concentration adjustment chamber 103. The smell concentration is adjusted by controlling the gas flow rate and the multi-layer ventilation film 9. , the smell is output from the air hood B12, and the dog inhales from the opening of the air hood B12 and makes a judgment. According to conventional cognition, when the dog determines that the current smell is different from the smell information obtained from the air hood A7, it will not send out a barking signal, and then start the motor 17 to send each object to be detected into the placement slot corresponding to the air suction end of the fan 13 in turn. The fan 13 inputs different air sources into the air hood B12. When the air source is the same as the air source output by the air hood A7, if the dog barks, it indicates that the detection has passed, and then switch to the next object, and let the dog smell the target air source information from the air hood A7 first, and then repeat the above actions.

[0024] Embodiment 2

[0025] like Figure 1 and Figure 2 As shown, in the dog olfactory sensitivity test auxiliary device proposed by the utility model, compared with the first embodiment, the lower edges of the openings of the air suction hood A7 and the air suction hood B12 are both inclined downward in the direction away from the box body 1.

[0026] In this embodiment, in hot weather or when the dog's body temperature is too high, the dog will dissipate heat through the mouth and produce a large amount of saliva. The lower edge of the opening of the suction hood is set downward to facilitate the discharge of saliva and prevent the saliva from entering the box 1 through the pipe.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
