Description

Technical Field

[0001] This utility model belongs to the technical field of olfactory detection equipment, specifically relating to a physical examination auxiliary device for olfactory examination. Background Technology

[0002] Smell is a fundamental human sensory ability, and olfactory testing is often required during physical examinations. To improve the convenience of olfactory examinations, there is a certain demand for olfactory testing devices. Currently, most olfactory examinations involve placing several different bottles on a table, shuffling them, and then removing the stoppers one by one for smelling and identification. This method is not only cumbersome and time-consuming, but also prone to errors when multiple people are being examined simultaneously, as the order of the bottles can easily be remembered by the next person, resulting in low accuracy. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a convenient auxiliary device for olfactory examination.

[0004] The present invention adopts the following technical solution:

[0005] An auxiliary device for olfactory examination includes a housing, an olfactory bottle rotation mechanism, a drive mechanism, a breathing mechanism, and a control mechanism. The housing has a breathing window communicating with its interior. The olfactory bottle rotation mechanism, located within the housing, includes a rotating disk rotatably mounted at the bottom of the housing, multiple olfactory bottles circumferentially distributed on the rotating disk, and a lever assembly within the housing for opening or closing the olfactory bottles. Each olfactory bottle includes a bottle body, a cap, a vent on the cap communicating with the interior of the bottle body, and a sealing plate rotatably mounted on the cap for closing the vent. One side of the sealing plate extends outward to form a push rod that cooperates with the lever assembly. The drive mechanism, located within the housing, connects to and drives the rotating disk to rotate. The breathing mechanism, located within the housing, connects the breathing window to the olfactory bottles. The control mechanism, located within the housing, connects to and controls the operation of the lever assembly, the drive mechanism, and the breathing mechanism.

[0006] Furthermore, the lever assembly includes a movable lever movably disposed on one side inside the housing, a drive motor connected to the movable lever and controlling the movable lever to rotate upward or downward, and a fixed lever disposed on the bottom surface of the housing at the center of the rotating disk and capable of cooperating with a push rod. The drive motor is connected to the control mechanism, and the movable lever and the fixed lever are arranged at intervals along the rotation direction of the rotating disk. The movable lever can rotate upward to drive the push rod to rotate to open the vent, and the fixed lever can cause the push rod to move in the opposite direction to close the vent.

[0007] Furthermore, the olfactory bottle also includes an arc-shaped moving groove on one side of the bottle cap, allowing the push rod to rotate back and forth. The fixed lever includes a main body extending upward from the bottom surface of the box, an extension extending outward from one side of the top of the main body, and a lever portion extending downward vertically on the extension. When the vent is closed, the push rod can move in the opposite direction to the leftmost end of the arc-shaped moving groove under the action of the lever portion, so that the front end of the push rod does not contact the lever portion.

[0008] Furthermore, the olfactory bottle rotating mechanism also includes a fixing component disposed between the olfactory bottle and the rotating disk. The fixing component includes a positioning groove disposed on the rotating disk for mounting the olfactory bottle and an elastic clamp disposed on one side of the positioning groove for fixing the olfactory bottle.

[0009] Furthermore, there are six olfactory bottles and six fixing components, each corresponding to one of the six olfactory bottles.

[0010] Furthermore, the drive mechanism includes a rotary motor disposed inside the housing and connected to the control mechanism, a rotary gear rotatably disposed at the bottom of the housing and connected to the output shaft of the rotary motor, and a gear section disposed at the bottom of the rotating disk and meshing with the rotary gear.

[0011] Furthermore, the breathing mechanism includes an airflow channel disposed inside the box and communicating with the breathing window, a breathing tube with one end connected to the airflow channel and the other end opposite to the vent, and a fan disposed inside the airflow channel and connected to the control mechanism for exhaling the odor from inside the olfactory bottle through the breathing window.

[0012] Furthermore, the control mechanism includes a control module disposed inside the box, a control screen disposed outside the box and connected to the control module, and a sensing module disposed between the multiple olfactory bottles and the box and connected to the control module. The control screen receives instructions transmitted by the sensing module through the control module.

[0013] Furthermore, the sensing module includes multiple NFC sensing chips disposed on multiple olfactory bottles and a sensor disposed inside the box that can sense the NFC sensing chips, with the multiple NFC sensing chips corresponding to the odors inside the multiple olfactory bottles.

[0014] Furthermore, the enclosure also includes a ventilation fan on one side that connects the interior of the enclosure to the outside, and an enclosure door on one side that can be opened. The ventilation fan is connected to a control mechanism.

[0015] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, by defining the specific structure of the olfactory bottle rotation mechanism, enables multiple olfactory bottles to connect with the breathing mechanism through the cooperation between the rotating disk, the lever assembly, the drive mechanism, and the control mechanism, allowing the tester to smell different odors. The housing is made of opaque material, effectively preventing the tester from judging the odor of the olfactory bottle based on the rotation pattern of the rotating disk during olfactory testing, thus improving the accuracy of the test. Simultaneously, by providing a lever assembly inside the housing for opening or closing the olfactory bottle, the vent of the previous olfactory bottle can be closed simultaneously when the vent of the next olfactory bottle is opened, ensuring that only one olfactory bottle is opened inside the housing during the testing process, guaranteeing the uniformity of the odor within the housing.

[0016] By coordinating the control module inside the box, the control panel outside the box, and the sensing modules between multiple olfactory bottles and the box, the olfactory detection process can be simplified, allowing the tester to complete the olfactory detection independently and improving the practicality of the physical examination auxiliary device.

[0017] By installing a ventilation fan on one side of the chamber to connect the inside of the chamber with the outside, excess odors are dispersed to the outside of the chamber through air flow, preventing the next tester from smelling the mixed odors remaining inside the chamber and thus affecting the olfactory test results.

Detailed Implementation

[0025] The present invention will be further described below through specific embodiments.

[0026] like Figure 1 As shown in the figure, this embodiment provides a physical examination auxiliary device for olfactory examination, including a housing 1, an olfactory bottle rotation mechanism 2, a drive mechanism 3, a breathing mechanism 4, and a control mechanism 5.

[0027] The chamber 1 includes a breathing window 11 located on the front surface of the chamber 1 and communicating with the interior of the chamber 1, a ventilation fan 12 located on the chamber 1 and communicating with the interior of the chamber 1 and the outside, and a door 13 located on the rear surface of the chamber 1 that can be opened. Specifically, the ventilation fan 12 is connected to the control mechanism 1. The ventilation fan 12 can disperse excess odors inside the chamber 1 to the outside of the chamber 1, so as to prevent the next tester from smelling the residual mixed odors inside the chamber 1 when conducting the olfactory test, which would affect the olfactory test results. Furthermore, the chamber 1 is made of opaque material, which can prevent the tester from judging the odor by observing the rotation pattern of the olfactory rotation mechanism 2.

[0028] The olfactory bottle rotating mechanism 2, housed within the housing 1, includes a rotating disk 21 rotatably mounted at the bottom of the housing 1, multiple olfactory bottles 22 circumferentially distributed on the rotating disk 21, and a lever assembly 23 within the housing 1 for opening or closing the olfactory bottles 22. Each olfactory bottle 22 includes a bottle body 221, a cap 222, a vent 223 on the cap 222 communicating with the interior of the bottle body 221, and a sealing plate 224 rotatably mounted on the cap 222 for closing the vent 223. One side of the sealing plate 224 extends outward to form a push rod 225 that engages with the lever assembly 23. The lever assembly 23 allows the opening of the next olfactory bottle. When the vent 223 of the olfactory bottle 22 is opened, the vent 223 of the previous olfactory bottle 22 is simultaneously closed, ensuring that only one olfactory bottle 22 is opened in the chamber 1 during the testing process, thus guaranteeing the uniformity of the odor within the chamber 1. Specifically, the lever assembly 23 includes a movable lever 25 movably disposed on one side inside the chamber, a drive motor 26 connected to and controlling the movable lever 25 to rotate upwards or downwards, and a fixed lever 27 disposed on the bottom surface of the chamber 1 at the center of the rotating disk 21, which can cooperate with the push rod. The drive motor 26 is connected to the control mechanism 5, and the movable lever 25 and the fixed lever 27 rotate along the rotating disk 21. The olfactory bottle 22 is arranged at intervals. The movable lever 25 can rotate upward to drive the push rod 225 to rotate and open the vent 223. The fixed lever 27 can move the push rod 225 in the opposite direction to close the vent 223. Furthermore, the olfactory bottle 22 also includes an arc-shaped moving groove 226 provided on one side of the bottle cap 222 for the push rod 225 to rotate back and forth. The fixed lever 27 includes a main body 271 extending upward from the bottom surface of the box 1, an extension 272 extending outward from one side of the top of the main body 271, and a lever part 273 extending downward vertically on the extension 272. When the vent 223 is closed, the push rod 225 can move in the direction of the lever part 273. The push rod 225 is moved to the leftmost end of the arc-shaped moving groove 226 in the reverse direction, so that the front end of the push rod 225 does not contact the lever part 273. Furthermore, the olfactory bottle rotating mechanism 2 also includes a fixing component 24 disposed between the olfactory bottle 22 and the rotating disk 21. The fixing component includes a positioning groove 28 disposed on the rotating disk for mounting the olfactory bottle and an elastic clamp 29 disposed on one side of the positioning groove for fixing the olfactory bottle. Through the cooperation between the positioning groove 28 and the elastic clamp 29, it is convenient for medical staff to disassemble and install the olfactory bottle 22. Furthermore, there are six olfactory bottles 22 and six fixing components 24, which correspond one-to-one with the six olfactory bottles 22.

[0029] The drive mechanism 3, located inside the housing 1, connects to and drives the rotating disk 21 to rotate. It includes a rotating motor 31 located inside the housing 1 and connected to the control mechanism 5, a rotating gear 32 rotatably located at the bottom of the housing 1 and connected to the output shaft of the rotating motor 31, and a gear part 33 located at the bottom of the rotating disk 21 and meshing with the rotating gear 32. Specifically, in use, the rotating motor 31 drives the rotating disk 21 to rotate through the cooperation of the rotating gear 32 and the gear part 33, thereby making the different olfactory bottles 22 face the breathing mechanism 4.

[0030] Breathing mechanism 4, located inside housing 1, connects breathing window 11 and olfactory bottle 22. It includes an airflow channel 41 located inside housing 1 and connected to breathing window 11, a breathing tube 42 with one end connected to airflow channel 41 and the other end opposite to vent 223, and a fan 43 located inside airflow channel 41 and connected to control mechanism 5 for exhaling the odor inside relative olfactory bottle 22 through breathing window 11. Specifically, in use, the fan 43 causes the odor of relative olfactory bottle 22 to enter breathing window 11 through breathing tube 42 and airflow channel 41 for the tester to smell.

[0031] The control mechanism 5, located inside the housing 1, connects to and controls the operation of the lever assembly 23, the drive mechanism 3, and the breathing mechanism 4. It includes a control module 51 inside the housing 1, a control panel 52 outside the housing 1 connected to the control module 51, and a sensing module 53 located between the multiple olfactory bottles 22 and the housing 1 and connected to the control module 51. The control panel 52 receives instructions from the sensing module 53 through the control module 51. Through the cooperation of the control module 51, the control panel 52, and the sensing module 53, the olfactory detection process can be simplified, allowing the user to complete the olfactory detection independently, thus improving the practicality of the medical examination auxiliary device. Specifically, the sensing module 53 includes components installed inside the housing 1. Multiple NFC sensing chips 54 are mounted on multiple olfactory bottles 22, and a sensor 55 capable of sensing the NFC sensing chips 54 is disposed inside the housing 1. The multiple NFC sensing chips 54 correspond to the odors inside the multiple olfactory bottles 22. Furthermore, the control screen 52 is a common touch screen device in the prior art. When in use, the control screen 52 will display multiple odor options, one of which corresponds to the sensing module. When the tester selects a certain odor option, the control screen 52 will display "correct" or "incorrect". Furthermore, the control module 51 can be a microcontroller or other controllers in the prior art that can achieve the above effects. The specific model and working principle will not be further described here.

[0032] The specific operating procedure for this application is as follows:

[0033] Step 1: At the start of the test, the control module 51 controls the rotating motor 31 to work, which drives the rotating disk 21 and the six olfactory bottles 22 on the rotating disk 21 to rotate. When the rotating disk 21 stops and one of the olfactory bottles 22 is opposite to the breathing tube 42, the control module 51 controls the drive motor 26 to work. The drive motor 26 first drives the movable lever 25 to rotate upward, thereby driving the push rod 225 of the olfactory bottle 22 opposite to the movable lever 25 to move forward in the arc-shaped moving groove 226 and open the air vent 223. The drive motor 26 then drives the movable lever 25 to move downward to the original position. Then, the control module 51 controls the fan 43 to work, and the odor in the olfactory bottle 22 is exhaled through the breathing tube 42 and the fan 43 from the breathing window 11 and smelled by the test subject. At this time, the sensor detects the NFC sensor 54 on the olfactory bottle 22, and the control screen 52 displays six odor options. When the test subject selects a certain odor option, the control screen will display whether it is correct or incorrect.

[0034] Step Two: When conducting the next test, the control module 51 continues to control the rotating motor 31 to drive the rotating disk 21 to rotate. During the rotation, the opened olfactory bottle 22 on the rotating disk 21 passes through the fixed lever 27. The lever part 273 contacts the front end of its push rod 255, causing the push rod 225 to move in the opposite direction within the arc-shaped moving groove 226. This moves the push rod 225 to the leftmost end of the arc-shaped moving groove 226 and closes the vent 223 of the olfactory bottle 22. At this time, the front end of the push rod 225 does not contact the lever part 273. The rotating disk 21 and the six olfactory bottles 22 on the rotating disk 21 continue to rotate, repeating the operation of Step One, allowing the tester to continue smelling the odor of the next olfactory bottle. The olfactory testing steps are simple and easy to understand. The tester can complete the olfactory test independently by operating the control panel.

[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, through the cooperation between the rotating disk 21, the lever assembly 23, the drive mechanism 3, and the control mechanism 5, different olfactory bottles 22 are connected to the breathing mechanism 4, enabling the tester to smell different odors. Furthermore, the lever assembly 23, located within the housing 1, allows the vent 223 of the previous olfactory bottle 22 to be closed simultaneously when the vent 223 of the next olfactory bottle 22 is opened, ensuring that only one olfactory bottle 22 is opened within the housing 1 during the testing process, guaranteeing the uniformity of the odor within the housing 1. Additionally, the housing 1 is made of an opaque material, allowing for... This is to prevent testers from judging the odor of the olfactory bottle 22 by observing the rotation pattern of the olfactory rotating mechanism 2; in addition, the cooperation between the control module 51, the control screen 52 and the sensing module 53 can simplify the olfactory testing steps, allowing testers to complete the olfactory test independently and improving the practicality of the physical examination auxiliary device; furthermore, the ventilation fan 12 can disperse excess odors inside the chamber 1 to the outside of the chamber 1, preventing the next tester from smelling the residual mixed odors inside the chamber 1, which would affect the olfactory test results; in addition, the cooperation between the positioning groove 28 and the elastic clamp 29 facilitates the disassembly and installation of the olfactory bottle 22 by medical staff.

[0036] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
