Description

Technical Field

[0001] This application relates to electronic aroma diffusers, and more specifically to a temperature measuring mechanism and an electronic aroma diffuser. Background Technology

[0002] An electronic aroma diffuser is a small household appliance that uses electricity to effectively diffuse essential oils or solid fragrances into the air. A common type is the heated aroma diffuser, which uses heat to release the fragrance of essential oils or solid fragrances. While simple in structure, it suffers from relatively low temperature control accuracy. Heated aroma diffusers with temperature sensing function use a heating element to heat a ceramic disc holding the essential oils or solid fragrances. A temperature sensing element is placed close to the surface of the heating element to monitor the temperature. When the set temperature is reached, the main control board receives the temperature information from the sensing element and stops heating, thus achieving temperature control. The inventors have found that this type of heated aroma diffuser suffers from uncontrollable internal assembly gaps due to assembly tolerances and part dimensional tolerances. This makes it impossible to guarantee that the temperature sensing element will be perfectly aligned with the surface of the heating element, resulting in relatively low temperature measurement and control accuracy, which needs improvement. Utility Model Content

[0003] The purpose of this application is to provide a temperature measuring mechanism for an electronic aroma diffuser and an electronic aroma diffuser to improve the accuracy of temperature monitoring.

[0004] To achieve the above objectives, this application provides a temperature measuring mechanism for an electronic aromatherapy diffuser, comprising an upper cover, a component to be tested, a temperature measuring element, an elastic support assembly, and a lower cover. The upper cover has an inner cylinder, and the component to be tested is fixed in the inner cylinder of the upper cover. The temperature measuring element has a temperature measuring head and is fixed on the elastic support assembly. The temperature measuring element and the elastic support assembly are positioned between the lower cover and the component to be tested. The elastic support assembly is fixedly connected to the lower cover, and the lower cover is fixed to the lower end of the upper cover. The lower cover, through the elastic support assembly, tightly presses the temperature measuring head of the temperature measuring element against the surface of the component to be tested.

[0005] This application also provides an electronic aroma diffuser, which includes the temperature measuring mechanism of the above-mentioned technical solution.

[0006] The technical solution of this application uses a lower cover and an upper cover to be fixedly connected. The lower cover applies pressure to the temperature measuring element through an elastic support assembly, so that the temperature measuring head is pressed tightly against the surface of the part to be measured. This overcomes the problem of uncontrollable assembly gaps. The temperature measuring element can always be in contact with the part to be measured, which improves the accuracy of temperature monitoring, enhances the precision of temperature control, makes the temperature control function more complete, meets the usage requirements, and helps to improve product competitiveness.

In order to better understand the technical means of this application, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of this application more obvious and understandable, some embodiments are listed below and described in detail.

[0022] One or more embodiments of this application provide a temperature measuring mechanism 100 for an electronic aroma diffuser, the specific structure of which is as follows: Figures 1-6 As shown. Figure 1 This is a top view of the temperature measuring mechanism 100. Figure 2 This is a sectional view of section AA. Figure 3 This is a sectional view of section BB. (Combined with...) Figure 2 and Figure 3As shown, the temperature measuring mechanism 100 includes an upper cover 11, a component to be measured 22, a temperature measuring element 50, an elastic support assembly 30, and a lower cover 12. The upper cover 11 has an inner cylinder 111, and the component to be measured 22 is fixed in the inner cylinder 111 of the upper cover 11. The temperature measuring element 50 has a temperature measuring head 51, and the temperature measuring element 50 is fixed on the elastic support assembly 30. The temperature measuring element 50 and the elastic support assembly 30 are positioned between the lower cover 12 and the component to be measured 22, and the elastic support assembly 30 is fixedly connected to the lower cover 12. The lower cover 12 is fixed to the lower end of the upper cover 11, and the lower cover 12, through the elastic support assembly 30, tightly presses the temperature measuring head 51 of the temperature measuring element 50 against the surface of the component to be measured 22.

[0023] As can be seen, the temperature measuring structure is fixedly connected to the upper cover 11 through the lower cover 12. The lower cover 12 applies elastic pressure to the temperature measuring element 50 through the elastic support assembly 30, so that the temperature measuring head 51 is subjected to force and tightly attached to the surface of the part to be measured 22. This overcomes the problem of uncontrollable assembly gap, allowing the temperature measuring element 50 to always be attached to the part to be measured 22, improving the accuracy of temperature monitoring, enhancing the precision of temperature control, making the temperature control function more complete, and meeting the usage requirements.

[0024] In some embodiments, combined with Figure 2 and Figure 3 As shown, the component under test 22 is a heating element, which is fixed below the heat-conducting cup 21. The temperature measuring head 51 of the temperature measuring element 50 is attached to the lower surface of the component under test 22 to monitor the real-time temperature of the heating element. The heating element can be an alumina ceramic heating element, a PI film heating element, a silicone glass fiber heating element, or a PTC ceramic heating element. The heat-conducting cup 21 can be made of a high thermal conductivity ceramic material, such as PCD ceramic, SiC ceramic, or Si3N4 ceramic. The ceramic heat-conducting cup 21 combines the functions of thermal conductivity, high temperature resistance, and insulation, ensuring stability during high-temperature use and preventing electrical conduction between it and the temperature measuring element 50. Furthermore, a receiving groove 211 is provided below the heat-conducting cup 21, and the component under test 22 is fixed in the receiving groove 211 by means of snap-fit, interference fit, or adhesive.

[0025] In some embodiments, combined with Figure 2 and Figure 3As shown, the upper part of the inner cylinder 111 of the upper cover 11 forms a stepped surface 112. An upper heat insulation ring 41 is clamped between the upper end of the heat-conducting cup 21 and the stepped surface 112. The upper heat insulation ring 41 has a right-angled cross-section and is made of heat-insulating, high-temperature resistant silicone. The outer wall of the heat-conducting cup 21 is wrapped by a middle heat insulation sleeve 42, which is made of heat-insulating fiberglass. A lower heat insulation pad 43, made of heat-insulating cotton, is clamped between the lower end of the heat-conducting cup 21 and the lower cover 12. By wrapping the heat-conducting cup 21 with the upper heat insulation ring 41, the middle heat insulation sleeve 42, and the lower heat insulation pad 43, the heat conducted outward from the heat-conducting cup 21 is reduced, which is beneficial for the long-term high-temperature use of the electronic aromatherapy diffuser. In addition, both the upper cover 11 and the lower cover 12 are injection molded from high-temperature resistant plastic materials, improving their heat resistance and enhancing their stability under long-term high-temperature conditions.

[0026] In some embodiments, combined with Figure 2 , Figure 3 and Figure 4 As shown, the upper surface of the lower cover 12 contacts the lower heat insulation pad 43. An annular protrusion 121 is provided at the position where the sidewall of the heat-conducting cup 21 is projected onto the upper surface of the lower cover 12. The annular protrusion 121 applies pressure to the lower heat insulation pad 43, making the lower heat insulation pad 43 between the heat-conducting cup 21 and the lower cover 12 more tightly pressed. Furthermore, as... Figure 4 As shown, the lower cover 12 has four through holes 123. By screwing through the through holes 123 and into the threaded holes (not shown) on the side wall of the upper cover 11, the lower cover 12 and the upper cover 11 can be fixedly connected.

[0027] In at least one embodiment, such as Figure 2 As shown, a carrier cup 23 made of ceramic or high-temperature resistant plastic is placed in the heat-conducting cup 21. The carrier cup 23 is used to hold liquid or solid fragrance. The carrier cup 23 can be directly removed from the heat-conducting cup 21 for easy cleaning or replacement. In at least one embodiment, the temperature measuring head 51 of the temperature measuring element 50 is also fixedly connected to the surface of the component 22 to be measured by a high-temperature resistant adhesive, which makes temperature monitoring more accurate.

[0028] In some embodiments, combined with Figure 3 and Figure 4 As shown, the elastic support assembly 30 includes an elastic block 31 and a support block 32. Specifically, the elastic block 31 is made of elastic silicone, and the support block 32 is made of ceramic. The ceramic support block 32 is heat-resistant and insulating, which can prevent it from conducting electricity with the temperature sensing element 50. Figure 3 and Figure 4As shown, the support block 32 is embedded and fixed in the elastic block 31, and the top end 323 of the support block 32 protrudes outside the elastic block 31, avoiding contact between the top surface of the elastic block 31 and the surface of the component 22 to be measured. The elastic block 31 is inserted into and snapped into the mounting position 122 inside the lower cover 12. Specifically, the outer wall of the elastic block 31 is provided with two opposing hooks 311, and the inner wall of the mounting position 122 of the lower cover 12 is provided with corresponding slots 124. The hooks 311 are inserted into the slots 124 one by one to form a snap-fit ​​fixation. In at least one embodiment, the temperature sensing element 50 is an NTC temperature sensor. The temperature sensing head 51 of the temperature sensing element 50 is placed in the shallow groove 320 of the top end 323 of the support block 32, and the wire harness 52 of the temperature sensing element 50 passes through the support block 32, the elastic block 31, and the lower cover 12 in sequence. The upper part 510 of the temperature sensing head 51 protrudes above the surface of the top end 323 of the support block 32 to avoid contact between the support block 32 and the surface of the component 22 to be measured. In addition, such as Figure 3 As shown, the bottom center of the elastic block 31 is hollowed out 310 to reduce the wall thickness and improve the yield of injection molding.

[0029] In some embodiments, combined with Figure 4 and Figure 5 As shown, the elastic block 31 has an inner hole 312, and the support block 32 is embedded and fixed in the inner hole 312. The inner wall of the inner hole 312 has an annular groove 313, and the outer wall of the support block 32 has a circumferential protrusion 321. The circumferential protrusion 321 is placed in the annular groove 313 to form a mutual interlocking, so that the support block 32 and the elastic block 31 will not easily detach. Further, in at least one embodiment, the upper surface of the circumferential protrusion 321 is an inclined surface 3210. From the inside to the outside, the inclined surface 3210 slopes downward. The top surface 3130 of the annular groove 313 (see...) Figure 3 The tilt angle of the circumferential protrusion 321 matches the tilt surface 3210 of the circumferential protrusion 321.

[0030] In some embodiments, such as Figure 5 As shown, the bottom surface of the inner hole 312 has four evenly distributed protrusions 3121. The protrusions 3121 abut against the bottom surface of the support block 32, so that the support block 32 is pressed tightly in the inner hole 312 of the elastic block 31, and the support block 32 is not easy to loosen in the inner hole 312. In at least one other embodiment, there is at least one protrusion.

[0031] In some embodiments, such as Figure 6 As shown, the protruding portion 125 on the bottom surface of the lower cover 12 corresponds to the mounting position. Several reinforcing ribs 126 are provided around the protruding portion 125 to improve the rigidity of the lower cover 12 and reduce the deformation of the lower cover 12.

[0032] One or more embodiments of this application are electronic aroma diffusers, the specific structure of which is as follows: Figures 7 to 9 As shown. Combined with Figure 7 and Figure 8As shown, the electronic aroma diffuser includes an inner frame 80, a cylindrical outer shell 91, a base 93, and a temperature measuring mechanism 100 as described in one or more of the above embodiments. The inner frame 80 is enclosed by the outer shell 91, and the temperature measuring mechanism 100 is fixed to the upper end of the inner frame 80. The upper cover 11 has several exhaust holes 113, which are connected to the inner frame 80. A cooling fan 70 is fixed in the inner frame 80, located below the lower cover 12, and the airflow direction of the cooling fan 70 is towards the upper cover 11. The lower end of the inner frame 80 is fixedly connected to the base 93 by several screws. The side wall of the base 93 has two recesses 931, which, together with the lower end of the outer shell 91, form an air inlet 932 that connects to the inner frame 80. Airflow enters the inner frame 80 from the two air inlets 932, passes through the cooling fan 70, and then flows out from the exhaust holes 113 of the upper cover 11, reducing heat accumulation inside the inner frame 80 and facilitating long-term high-temperature use of the electronic aroma diffuser. In at least one other embodiment, the sidewall of the base has only one recess, which forms an air inlet with the lower end of the housing.

[0033] In some embodiments, combined with Figure 7 and Figure 8 As shown, the inner frame 80 includes a front frame 81 and a rear frame 82, which are interlocked. Specifically, the front frame 81 has four hooks 811 on its edge facing the rear frame 82, and the rear frame 82 has corresponding latching arms 821. The hooks 811 and latching arms 821 interlock to securely connect the front frame 81 and the rear frame 82. Figure 7 and Figure 8 As shown, the front frame 81 is snapped and fixed with the main control circuit board 61, while the rear frame 82 has a battery compartment 822, in which a rechargeable battery 62 is snapped and fixed. A charging port 63 is fixed between the rear frame 82 and the base 93. The charging port 63 is located on the sub-circuit board 631 and is electrically connected to the main control circuit board 61 through the sub-circuit board 631. The main control circuit board 61 is electrically connected to the battery 62 and the cooling fan 70 respectively.

[0034] In some embodiments, such as Figure 8 As shown, the main control circuit board 61 is equipped with control buttons 611 for adjusting the operating parameters of the electronic aroma diffuser, such as temperature. Figure 9 As shown, the outer casing 91 is equipped with button caps 911, which are connected one-to-one with the control buttons 611. Figure 8 As shown, the main control circuit board 61 is also equipped with a display screen 612 for displaying real-time information of the electronic aroma diffuser, such as temperature. In at least one other embodiment, such as Figure 10As shown, the main control circuit board 61 is equipped with a rotary encoder 613, which can be used to adjust the operating parameters of the electronic aroma diffuser, such as temperature. The outer casing 91 is equipped with a corresponding rotary button 913, which is fixedly connected to the rotary encoder 613. By operating the rotary button 913, the rotary encoder 613 can be rotated, thereby realizing parameter adjustment.

[0035] In some embodiments, combined with Figure 7 and Figure 8 As shown, below the lower cover 12, the front frame 81 has a semi-groove 813, and the rear frame 82 also has a semi-groove 823. Part of the cooling fan 70 is inserted into the semi-groove 813, and the other part is inserted into the semi-groove 823. The front frame 81 and the rear frame 82 are interlocked and fixed, so that the cooling fan 70 is clamped and fixed from the front and rear. In addition, the base 93 has two non-uniformly distributed positioning cylinders 933. The bottom ends of the front frame 81 and the rear frame 82 are respectively provided with corresponding positioning posts 804. The positioning posts 804 are inserted into the positioning cylinders 933 to achieve accurate positioning between the base 93 and the inner frame 80.

[0036] In some embodiments, combined with Figure 7 and Figure 8 As shown, the upper cover 11 of the temperature measuring mechanism 100 has sockets 117 on both sides. The front frame 81 and the rear frame 82 are each provided with a plug 805, which is inserted into the sockets 117. The front frame 81 and the rear frame 82 are interlocked and fixed together. Therefore, the temperature measuring mechanism 100 is clamped by the front frame 81 and the rear frame 82, and the temperature measuring mechanism 100 and the inner frame 80 are relatively fixed. In addition, the top of the outer shell 91 abuts against the upper cover 11, and the bottom of the outer shell 91 abuts against the base 93. The base 93 is fixedly connected to the bottom of the inner frame 80 by screws. Therefore, the outer shell 91 is clamped and fixed by the upper cover 11 and the base 93 from both the top and bottom.

[0037] In some embodiments, such as Figure 9 As shown, the electronic aroma diffuser also includes a top cover 92, which covers the upper cover 11. The upper end of the top cover 92 has a ventilation grille 921. When the electronic aroma diffuser is working, the internal airflow is discharged upwards through the exhaust port 113 of the upper cover 11, and finally exits from the ventilation grille 921 of the top cover 92. This achieves internal heat dissipation while also accelerating the discharge of the fragrant gas generated by the heating of the fragrance in the container 23 through the ventilation grille 921 of the top cover 92. Figure 9As shown, the top cover 92 has two latches 922 on its side wall, and the upper cover 11 has a boss 118. The side wall of the boss 118 has circumferential grooves 119 that correspond one-to-one with the latches 922. When installing the top cover 92, first let the top cover 92 cover the upper cover 11. At this time, the latches 922 are offset from the grooves 119. Then, rotate the top cover 92 clockwise so that the latches 922 are inserted into the grooves 119 respectively to form a snap-fit, and finally fix the top cover 92 to the upper cover 11.

[0038] The above examples are merely illustrative of the technical content of this application to facilitate reader understanding, but do not imply that the implementation methods of this application are limited to these. Any technical extensions or re-creations made based on this application are protected by this application. The scope of protection of this application is determined by the claims.
