Description

Technical Field

[0001] This application relates to the field of odor search, and more particularly to an odor search extension device. Background Technology

[0002] Police dog technology is increasingly used in public safety fields such as evidence search, scent recognition, security, and fire rescue, highlighting its unique and irreplaceable role due to its speed, efficiency, simplicity, and accuracy. However, there are challenges in using police dogs, including areas at heights exceeding 1.5 meters, dangerous enclosed spaces, buried areas beyond their olfactory range, and inside cargo vehicles. Therefore, a scent-searching device is needed to assist police dogs in performing scent-searching tasks in these special environments.

[0003] A search revealed a wearable scent-detecting device for police dogs in Chinese patent document CN202322178664.4. This device is worn by the handler, with the scent collection tube located beside the handler. The collected scent is not directly delivered to the dog's nose, which can easily lead to cross-contamination and identification errors. Furthermore, the device has a relatively complex structure. Summary of the Invention

[0004] The purpose of this application is to provide an odor search extension device that can perform odor search in locations where police dogs cannot directly sniff and identify, such as high places or narrow spaces.

[0005] To achieve the above objectives, this application provides the following technical solution: This application provides an odor search extension device, including an odor collection head, an operating unit, a gas pipeline, and a snorting mask. The odor collection head is installed at the front end of the operating unit to be aimed at the area where the odor needs to be collected; The operating unit is a handheld component, which facilitates the adjustment of the direction of the odor collection head; The two ends of the gas pipe are respectively connected to the rear end of the operating unit and the sniffing mask, so as to transmit the odor collected by the odor collection head to the sniffing mask. The sniffing mask is worn on the face of the police dog to transmit the collected scent to the dog's nose for sniffing.

[0006] The sniffing mask is equipped with an airflow dispersion head at its air inlet to disperse the gas transmitted from the gas pipeline.

[0007] The sniffing mask is also equipped with a mask connector for connecting to a gas pipeline. Both ends of the gas pipeline are equipped with pipe connectors, and the rear end of the operating unit is equipped with an output connector. The gas pipeline is connected to the output connector and the mask connector respectively through the pipe connectors at both ends.

[0008] The sniffing mask is also provided with a connection hole, and a fixing strap is provided in the connection hole to fix the sniffing mask to the face of the police dog.

[0009] The odor collection head is provided with a collection connector at the connection between the odor collection head and the operating unit. The front end of the operating unit is provided with an input connector. The collection connector is inserted into the input connector to complete the connection between the odor collection head and the operating unit.

[0010] The output connector, input connector, and mask connector of the operating unit are female connectors, and the pipe connector and acquisition connector are male connectors. The female connector is provided with a slot, and the male connector is provided with a locking block. The male connector is inserted into the female connector and locked into the slot by the locking block to achieve a quick connection between the male and female connectors.

[0011] The operating unit is equipped with an air pump, which is connected to a battery installed in the operating unit. The operating unit is also equipped with an air pump switch and an airflow adjustment knob for adjusting the air pump's suction speed.

[0012] The gas pipeline is made of flexible hose or retractable plastic film.

[0013] Compared with existing technologies, the advantages of this application are: by adjusting the collection point of the collection head through the operating unit, it is possible to collect and search for odors at heights or in narrow spaces that are inaccessible to police dogs. The designed gas pipeline and sniffing mask can directly deliver the collected odors to the police dog without any odor mixing in between. In addition, to prevent the gas from the inhalation pump from blowing directly onto the police dog's nose, an airflow dispersion head is used to disperse the direct current gas, further increasing the accuracy of odor recognition. The entire device has a simple structure, is easy to use, and meets the needs of various scenarios for police dog searches. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0017] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0018] like Figures 1 to 5 As shown, please refer to Figure 1 This application provides an odor search extension device, including an odor collection head 1, an operation unit 2, a gas pipe 3, and a sniffing mask 4. The odor collection head 1 is installed at the front end of the operation unit 2 to be aimed at the part where the odor needs to be collected; The operating part 2 is a handheld component, which facilitates the adjustment of the direction of the odor collection head 1; The two ends of the gas pipe 3 are respectively connected to the rear end of the operation unit 2 and the sniffing mask 4, so as to transmit the odor collected by the odor collection head 1 to the sniffing mask 4. The sniffing mask 4 is worn on the face of the police dog to transmit the collected scent to the dog's nose for sniffing. The sniffing mask 4 can be made of flexible silicone material, which can not only meet the comfort of the police dog, but also have a certain rigidity and strength, thereby ensuring that there is an appropriate amount of air storage space between the police dog's nose and the air inlet, reducing the problem of insufficient recognition accuracy of flowing air.

[0019] The sniffing mask 4 is equipped with an airflow dispersion head 5 at its air inlet to disperse the gas transmitted from the gas pipe 3.

[0020] The sniffing mask 4 is also provided with a mask connector 8 for connecting to the gas pipe 3. Both ends of the gas pipe 3 are provided with pipe connectors 7, and the rear end of the operation unit 2 is provided with an output connector 6. The gas pipe 3 is connected to the output connector 6 and the mask connector 8 respectively through the pipe connectors 7 at both ends.

[0021] like Figure 2 As shown, the sniffing mask 4 is also provided with a connection hole 9, and a fixing strap 10 is provided in the connection hole 9 for fixing the sniffing mask 4 to the face of the police dog.

[0022] The odor collection head 1 is provided with a collection connector 11 at the connection between the odor collection head 1 and the operation unit 2. The front end of the operation unit 2 is provided with an input connector 13. The collection connector 11 is inserted into the input connector 13 to complete the connection between the odor collection head 1 and the operation unit 2.

[0023] like Figure 3 and Figure 4 As shown, the output connector 6, input connector 13, and mask connector 8 of the operation unit 2 are female connectors, and the pipe connector 7 and the acquisition connector 11 are male connectors. The female connector is provided with a slot 14, and the male connector is provided with a locking block 12. The male connector is inserted into the female connector and locked into the slot 14 by the locking block 12 to achieve a quick connection between the male and female connectors.

[0024] like Figure 5 As shown, the operating unit 2 is equipped with an air pump, which is connected to a battery installed in the operating unit 2. The operating unit 2 is also equipped with an air pump switch 16 and an airflow adjustment knob 15 for adjusting the air pump's suction speed. The air pump and battery in the operating unit 2 are conventional components, and commercially available handheld car vacuum cleaners can meet the usage requirements.

[0025] The gas pipe 3 is made of flexible hose or retractable plastic film. It is best to make the gas pipe 3 with plastic film because the pipe will have residual odor after a long period of use. Therefore, using plastic film, which is easy to replace and economical, is the most cost-effective option. When replacing the pipe, simply separate the pipe joint 7 from the plastic film, and then cut the plastic film to the required size and stick it to the pipe joint to replace the gas pipe.

[0026] When using it, first fix the sniffing mask 4 on the head of the police dog so that the dog's nose is aligned with the airflow dispersion head 5. Connect the pipe connectors 7 at both ends of the gas pipe 3 to the operating unit 2 and the sniffing mask 4 respectively. The handler holds the operating unit 2, turns on the air pump switch, and aims the scent collection head 1 at the place where scent needs to be collected. The collected scent passes through the gas pipe 3 and is slowed down by the airflow dispersion head 5 before reaching the dog's nose. The dog can then identify the scent at the collection site.

[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
