[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] See also Figure 1 —6. A multifunctional electronic nose, comprising a housing 1, a circuit board 2 and a gas sensor 3;
[0030] The housing 1 includes an upper shell 11, a lower shell 12 and a ventilation shell 13. The upper shell 11 and the lower shell 12 are connected by a tenon. The circuit board 2 is arranged inside the lower shell 12. The gas sensor 3 is arranged between the upper shell 11 and the lower shell 12. The ventilation shell 13 is connected to one end of the upper shell 11 and the lower shell 12. The gas sensor 3 maintains a data connection with the circuit board 2.
[0031] One end of the vent shell 13 is a flat wedge-shaped structure, and the other end is a cylindrical structure. A vent hole 14 is opened at one end of the flat wedge-shaped structure of the vent shell 13, and a vent cavity 15 is formed inside the vent shell 13.
[0032] The housing 1 specifically includes an upper housing 11, a lower housing 12 and a vent housing 13. Figure 2 and Figure 3 As shown, tenons are provided on the inner walls adjacent to the lower shell 12 and the upper shell 11, and the upper shell 11 and the lower shell 12 can be simply spliced together by the tenons, which can be convenient for installation workers to install. One end of the ventilation shell 13 is a flat wedge-shaped structure, and the other end is a cylindrical structure, and the interior of the ventilation shell 13 is a hollow structure. The cylindrical structure at one end of the ventilation shell 13 is adapted to the diameter of the circular structure formed at the rear end portion of the upper shell 11 and the lower shell 12 when they are spliced, so that the ventilation shell 13 can be installed to one end of the upper shell 11 and the lower shell 12, and a vent 14 is provided at one end of the flat wedge-shaped structure of the ventilation shell 13. Specifically, the vent 14 is a flat structure, and the aspect ratio of the vent 14 is 3:0.2, with a narrow air intake structure, which can increase the air intake flow rate during air intake and ensure the gas flow entering the vent 14.
[0033] Furthermore, a plurality of positioning blocks are provided inside the lower shell 12, and a plurality of positioning openings are provided on the outer wall of the circuit board 2. The circuit board 2 is plugged into the positioning blocks provided inside the lower shell 12 through the positioning openings on the outer wall, so as to facilitate the positioning of the circuit board 2.
[0034] The gas sensor 3 is connected to the circuit board 2. The gas sensor 3 can transmit the detected gas data to the circuit board 2. The gas data is analyzed and calculated by the processing unit set on the circuit board 2, and the results are finally displayed. It should be pointed out that the analysis and calculation of the gas data by the processing unit set on the circuit board is the prior art in this technical field. Its specific structure and working principle are all prior art and will not be elaborated here.
[0035] In the utility model, the user blows the gas inside the oral cavity into the ventilation shell 13 through the ventilation hole 14 opened at one end of the flat wedge-shaped structure of the ventilation shell 13, and detects the gas through the gas sensor 3 arranged between the upper shell 11 and the lower shell 12. After the gas enters the ventilation cavity 15 through the ventilation hole 14 at one end of the ventilation shell 13, the flow rate slows down, which can facilitate the detection by the gas sensor 3, thereby improving the detection accuracy of the gas sensor 3. The circuit board 2 is installed in the lower shell 12 of the outer shell 1 and keeps connected with the gas sensor 3. The gas sensor 3 detects the inflowing gas and transmits the data to the circuit board 2, and displays it through the circuit board 2, so that the user can observe the measurement results conveniently. At the same time, the volume is small, which is convenient for the user to carry, and the user can perform oral gas detection at any time, which can improve the convenience of the user. By detecting the oral gas at any time, the user can quickly obtain some information about his or her health.
[0036] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, a first baffle 111 is provided on the circumferential outer wall of the upper shell 11, and the first baffle 111 protrudes from the upper shell 11. A second baffle 121 is provided on the circumferential inner wall of the lower shell 12, and the second baffle 121 protrudes from the lower shell 12. Preferably, vents are provided between the two sides of the second baffle 121 and the lower shell 12, and a circuitous air path 16 is formed between the first baffle 111 protruding from the upper shell 11 and the second baffle 121 protruding from the lower shell 12, as shown in FIG. Figure 2As shown, the airflow blown by the user enters the ventilation cavity 15 through the ventilation shell 13. After the gas enters the ventilation cavity 15, the diameter becomes larger and the gas flow rate becomes slower, so that the airflow can move parallel to the second baffle 121. When the airflow flows through the second baffle 121, a part of the airflow moves along the second baffle 121 under the action of the second baffle 121, and another part of the airflow continues to move through the vent between the second baffle 121 and the lower shell 12. Another part of the airflow flows through the outer wall of the first baffle 111 and keeps moving along the outer wall of the first baffle 111. Under the action of the continuous inflow of airflow, it flows through the gas sensor 3, thereby ensuring that the gas sensor 3 can detect the blown-in gas. At the same time, the circuitous air path 16 can prevent the blown-in gas from directly contacting the gas sensor 3, causing the temperature of the gas sensor 3 to drop, and can improve the detection accuracy of the gas sensor 3.
[0037] As a further embodiment provided by the present utility model, Figure 2 and Figure 3 As shown, an exhaust hole 122 is opened on the outer wall of one side of the lower shell 12. The number of the exhaust holes 122 is several, and preferably the several exhaust holes 122 are distributed in a circular array on the outer wall of one side of the lower shell 12. The gas flowing through the gas sensor 3 can be discharged from the shell 1 through the exhaust holes 122. When in use, the exhaust holes 122 are away from the user, which can prevent the exhausted gas from re-entering the inside of the shell 1 with the blown-in gas.
[0038] As an embodiment provided by the utility model, Figure 2 and Figure 3 As shown, a first through hole is opened on the circumferential outer wall of the upper shell 11, and a button shell 17 is movably installed inside the first through hole. A switch is arranged on the circuit board 2, and the setting position of the button shell 17 is adapted to the switch position on the circuit board 2. The user can drive the switch to be turned on or off by pressing the button shell 17, which is convenient for the user to operate.
[0039] As a further embodiment provided by the present utility model, Figure 3 As shown, a second through hole is opened on the circumferential outer wall of the upper shell 11, and a light guide column 18 is arranged inside the second through hole. Preferably, the number of the second through holes is several, and the several second through holes are distributed in a linear array on the circumferential outer wall of the upper shell 11. An indicator light is arranged on the circuit board 2. The setting position of the light guide column 18 is adapted to the setting position of the indicator light, so that the light of the indicator light can be guided to the outside of the shell 1 when in use, which is convenient for the user to observe.
[0040] It should be pointed out that a switch is provided on the circuit board 2, and the on or off control is performed by the switch, which is a conventional technology in the field. The display of the test results by the indicator light can be realized by software programming, which does not belong to the protection scope of the present utility model, and therefore, it will not be elaborated here.
[0041] A lithium battery is disposed inside the lower shell 12 , and the lithium battery is electrically connected to the switch, the indicator light and the gas sensor 3 .
[0042] As a further embodiment provided by the present utility model, Figure 5 and Figure 6 As shown, wedge blocks 19 are provided on the outer walls at both ends of the upper shell 11 and the lower shell 12, and a groove adapted to the wedge block 19 is provided on the inner wall of one end of the vent shell 13. The vent shell 13 can be clamped with the upper shell 11 and the lower shell 12 through the groove, so that the wedge block 19 at one end of the upper shell 11 and the lower shell 12 is embedded in the groove at one end of the vent shell 13. The vent shell 13 can limit one end of the upper shell 11 and the lower shell 12 to prevent the upper shell 11 and the lower shell 12 from loosening. Further, as shown in FIG. Figure 5 As shown, a positioning groove 112 is opened on the inner wall of the end of the upper shell 11, and a positioning piece 131 is fixedly installed on the inner wall of the end of the ventilation shell 13. The positioning groove 112 is adapted to the positioning piece 131. During installation, the positioning piece 131 on the ventilation shell 13 can be plugged into the positioning groove 112 of the upper shell 11 to quickly determine the installation direction of the ventilation shell 13, which is convenient for the installation of the ventilation shell 13.
[0043] As an embodiment provided by the utility model, Figure 6 As shown, it also includes a connecting shell 4, a recessed portion 113 is provided at the end of the upper shell 11 away from the ventilation shell 13, and a connecting hole 41 is provided on the circumferential outer wall of the connecting shell 4. Specifically, the connecting hole 41 is a concave structure, and the concave structure of the connecting hole 41 can be accommodated by the recessed portion 113. The user can hang a sling through the connecting hole 41 with the concave structure for easy carrying.
[0044] Preferably, a groove compatible with the wedge block 19 is opened on the inner wall at the end of the connecting shell 4, and the connecting shell 4 can be clamped with the end of the upper shell 11 and the lower shell 12 away from the ventilation shell 13 through the groove, thereby limiting one end of the upper shell 11 and the lower shell 12 to prevent the upper shell 11 and the lower shell 12 from loosening.
[0045] As a further embodiment provided by the present utility model, Figure 3 and Figure 2 As shown, a snap-in groove 10 is provided on the circumferential inner wall of the upper shell 11 and the lower shell 12, and a foam pad 5 is provided on the gas sensor 3. The gas sensor 3 is snapped into the snap-in groove 10 through the foam pad 5. The snap-in groove 10 provided on the upper shell 11 and the lower shell 12 can effectively position the foam pad 5. At the same time, the foam pad 5 can prevent moisture in the gas blown in by the user from contacting the circuit board 2 and causing damage to the circuit board 2.
[0046] Those skilled in the art will appreciate that other similar connection methods may also be used to implement the present invention, such as welding, bonding or screwing.
[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
