[0020] The utility model provides a metering device.

[0021] Please refer to Figure 1 In an embodiment of the present application, the metering device comprises a support assembly 10, a heating assembly 30, an atomizing rod 40 and a detection assembly 20. The support assembly 10 has an air duct 16 inside. The heating assembly 30 is arranged in the air duct 16. The atomizing rod 40 is detachably inserted into the heating assembly 30. The detection assembly 20 is arranged on the support assembly 10 and is used to measure the number of temperature changes in the air duct 16 for counting.

[0022] The support assembly 10 is used to provide a mounting space. One end of the support assembly 10 serves as a suction nozzle or is used to connect with a suction nozzle. The other end is used to insert the atomizing rod 40. The heating assembly 30 is also arranged in the support assembly 10. When the atomizing rod 40 is inserted into the support assembly 10, it is connected with the heating assembly 30. The atomizing rod 40 is heated by the heating assembly 30 to achieve the atomizing effect.

[0023] When the heating assembly 30 generates heat, the support assembly 10 is heated. When the user performs a suction action, the external cold air flows through the air duct 16 to the side connected with the suction nozzle, thereby taking away the heat and reducing the temperature in the air duct 16. When the user performs a suction action, the temperature in the support assembly 10 rises first and then falls.

[0024] The detection assembly 20 is used to detect the temperature of the air duct 16 in real time. When the temperature in the air duct 16 changes, it is recorded once, indicating that the user performs a suction action. In this embodiment, only one detection assembly 20 is arranged. The detection of the number of suction actions and the recording can be achieved by detecting the temperature in the air duct 16. The structure is simple, the overall cost is low, and the detection efficiency is high.

[0025] In an embodiment, the support assembly comprises a housing and a base arranged in the housing. The housing and the base are both provided with through holes to form the air duct when the base is connected with the housing. The base is provided with a mounting hole, and the detection assembly is arranged in the mounting hole.

[0026] The support assembly 10 is specifically composed of a housing and a base 13. The housing is internally provided with a through hole. The base 13 is arranged in the through hole of the housing. The base 13 is also provided with a through hole. When the base 13 is mounted in the housing, the through hole of the base 13 and the through hole of the housing are communicated to form the air duct 16.

[0027] The hole diameters at different positions of the shell are inconsistent. For example, the hole diameter of the shell at the position where the base 13 is mounted is larger, so that the lower base 13 can be mounted. The position of the shell other than the base 13 can be set to be consistent with the hole diameter of the through hole of the base 13, and the end portion of the base 13 has a stepped sealing structure at the abutting position, so as to ensure the sealing of the air duct 16 and prevent the aerogel from leaking from the air duct 16 when the user smokes.

[0028] Specifically, the shell is composed of an upper support 11 and a lower support 12. One end of the lower support 12 is connected to the upper support 11, and the other end extends away from the upper support 11 as a mouthpiece or for connecting with a mouthpiece.

[0029] Please refer to Figure 2 The upper support 11 has a first tube hole 111, and the lower support 12 has a second tube hole 121. The base 13 is mounted at the connection position of the lower support 12 and the upper support 11. Therefore, the left side of the second tube hole 121 has a larger inner diameter for accommodating the base 13, and the right side of the second tube hole 121 has a smaller inner diameter. When the right side of the base 13 abuts against the left side of the lower support 12, the hole diameter of the right side of the second tube hole 121 can be adapted to the inner diameter of the through hole of the base 13.

[0030] It should be noted that, please refer to Figure 2 The outer wall of the mounting tube is further provided with a limiting plate, and the lower support has a limiting groove. When the base is connected to the lower support, the limiting plate is clamped in the limiting groove.

[0031] The left side of the second tube hole 121 has a stepped structure, and the base 13 abuts against the stepped structure to achieve a sealing effect. Furthermore, a limiting plate 131 is provided on the edge of the outer side wall of the base 13 in the circumferential direction, and a corresponding limiting groove 122 is provided on the inner wall of the second tube hole 121. When assembled, the limiting plate 131 is clamped in the limiting groove 122, thereby improving the connection stability between the base 13 and the lower support 12.

[0032] The left side of the base 13 extends into the first tube hole 111. In an embodiment, please continue to refer to Figure 2 The heating assembly includes a connecting tube and a heating element. One end of the connecting tube is connected to the through hole of the base, and the other end extends into the first tube hole. The atomizing rod is detachably inserted into the connecting tube, and the hole diameter of the connecting tube is adapted to the size of the atomizing rod. The heating element is sleeved on the part of the connecting tube located in the first tube hole.

[0033] The left side hole of the through hole of the base 13 is larger in size and is matched with the size of the atomizing rod 40. The connecting pipe 31 of the heating assembly 30 abuts against the left side of the base 13. Similarly, the left side of the base 13 is also provided with a stepped structure, and the connecting pipe 31 abuts against the stepped structure, thereby improving the connection sealing between the connecting pipe 31 and the base 13.

[0034] The left side of the connecting pipe 31 is fixedly connected with the left side of the upper support 11, and the heating element 32 is sleeved on the part of the connecting pipe 31 that protrudes from the base 13. The heating element 32 can be, for example, a copper wire. When the atomizing rod 40 is inserted into the upper support 11, it extends into the connecting pipe 31 and the larger left side hole of the base 13. The copper wire is heated by electrification to achieve atomization.

[0035] In an embodiment, please refer to Figure 2 The diameter of the first pipe hole 111 is larger than the outer diameter of the connecting pipe 31 and the outer diameter of the base 13, thereby forming an air layer gap between the outer wall of the upper support 11 and the outer wall of the connecting pipe 31. In this embodiment, on the one hand, the air layer gap can play a heat insulation effect, and on the other hand, it can also avoid the user's hand being scalded by the heat of the outer wall of the upper support 11 when the user inhales.

[0036] Please refer to Figure 2 The upper support includes a heat preservation part and a limiting part. One end of the heat preservation part is connected with the lower support, and the other end is connected with the limiting part. The diameter of the heat preservation part is larger than the diameter of the connecting pipe. The diameter of the limiting part is matched with the diameter of the atomizing rod.

[0037] The right side hole of the upper support 11 is larger, that is, the heat preservation part 112, and the left side hole gradually decreases to be matched with the diameter of the atomizing rod 40 to form a connecting part 113, thereby avoiding the gap between the atomizing rod 40 and the inner wall of the first pipe hole 111 when the atomizing rod 40 is inserted into the upper support 11, which causes the taste of the suction to be poor. The heat preservation part 112 and the connecting part 113 are smoothly connected.

[0038] In an embodiment, the detection assembly includes a processing module and a thermistor connected with the processing module; the base includes a mounting pipe and a mounting plate, the mounting pipe has a through hole, and the mounting pipe communicates with the through hole of the shell to form the air duct when the mounting pipe is arranged in the shell; a plurality of mounting plates are sequentially and first connected on the outer wall of the mounting pipe, and the mounting plates and the outer wall of the mounting pipe are enclosed to form the mounting hole. The part of the outer wall of the mounting pipe located in the mounting hole is recessed to the side of the through hole to form a stepped structure. The processing module is arranged in the mounting hole, and the thermistor is arranged in the stepped structure.

[0039] The detection assembly 20 is composed of a processing module 21 and a thermistor 22, the thermistor 22 is used to detect an analog signal and send the analog signal to the processing module 21, the processing module 21 converts the analog signal into a digital signal, judges whether the user performs a puffing action through the digital signal, so as to realize recording the number of puffs.

[0040] Specifically, please refer to Figure 2 and Figure 3 A plurality of mounting plates 133 are arranged on the outer wall of the base 13, and a mounting hole 132 with an open top is enclosed between the mounting plates 133 and the outer wall of the base 13. In this embodiment, the mounting hole 132 adopts a quadrangular prism structure, that is, four mounting plates 133 are connected in a rectangular shape.

[0041] The processing module 21 is installed in the mounting hole 132. In order to avoid the processing module 21 from falling off the opening, the aperture of the left side of the lower support 12 can be adjusted, so that the top opening of the mounting hole 132 abuts against the inner wall of the lower support 12 after the base 13 is installed, and the processing module 21 is sealed in the mounting hole 132.

[0042] The bottom wall of the mounting hole 132, that is, the outer wall of the base 13 enclosed between the four mounting plates 133, is recessed to the side of the through hole, forming an inverted trapezoidal or stepped structure, for placing the thermistor 22.

[0043] Since the outer wall of the base 13 at the position where the thermistor 22 is placed is recessed inward, the inner wall at this position is thinner, which can further improve the detection sensitivity of the thermistor 22 and improve the detection accuracy.

[0044] In an embodiment, please continue to refer to Figure 2 and Figure 3 The shell includes an upper support and a lower support, the upper support has a first pipe hole, the lower support has a second pipe hole, and the base is arranged between the upper support and the lower support, the first pipe hole, the second pipe hole and the through hole in the base correspond to form the air duct.

[0045] A wire passing hole is arranged on the side wall of the lower support 12. Through Figure 2 and Figure 3 It can be known that the wire passing hole is arranged at the corresponding position of the detection assembly on the support assembly, and the wire passing hole is used for the connecting wire on the detection assembly to pass out.

[0046] Since the base 13 is installed between the upper support 11 and the lower support 12, the gap between the lower support 12 and the base 13 is separated to form a separate cavity, and the connecting wire of the processing module 21 can pass out from the wire outlet and be connected with external processors, power supplies and other electronic components, without affecting the sealing of the air duct 16.

[0047] In an embodiment, referring to Figure 2 , the detection assembly is arranged on the air duct at a position downstream of the heating element.

[0048] When the user inhales, the airflow flows from left to right along the air duct 16, and the thermistor 22 in the detection assembly 20 is arranged at the downstream end of the heating element 32, i.e. on the right side of the thermistor 22.

[0049] The heating element 32 heats the atomizing rod 40, and the temperature in the base 13 also rises. When the user inhales, the high-temperature gas in the base 13 is drawn out, and the temperature in the base 13 drops. The thermistor 22 detects the temperature change, and the processing module 21 transmits the data of the temperature change to the external CPU for processing. At this time, it is recorded as one puff. With the user inhaling one puff, the temperature in the cavity rises again until the next inhalation, and the temperature in the base 13 drops again. This is repeated to achieve the function of recording the number of puffs.

[0050] The utility model also proposes a kind of atomizer, the atomizer includes the metering device as described above, and the specific structure of the metering device refers to the above embodiment, since the atomizer adopts all technical solutions of the above all embodiments, at least has all beneficial effects brought by the technical scheme of the above embodiment, and here is not repeated one by one.

[0051] The above is only the exemplary embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure transformation using the utility model specification and drawing contents, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
