Description

Technical Field

[0001] This utility model relates to the field of ceramic aromatherapy stove technology, specifically to a fireproof ceramic aromatherapy stove with adjustable fragrance diffusion. Background Technology

[0002] A ceramic aromatherapy diffuser is a type of diffuser made of a heat-resistant material that is fired at high temperatures. It is used to diffuse essential oils or fragrances, thereby enhancing the comfort of the environment. Common ceramic aromatherapy diffusers are designed with fireproof features.

[0003] Current fireproof ceramic aromatherapy diffusers mainly use temperature control chips for multi-level adjustment to adapt to the volatilization needs of different aromatherapy materials. At the same time, timers are used to avoid safety hazards caused by prolonged heating, meeting the needs of scenarios such as sleep and office. Furthermore, overheat protection is included, which automatically cuts off the power and stops heating when the temperature exceeds the safety threshold.

[0004] In practical use, ceramic aroma diffusers control the diffusion efficiency of fragrance by controlling the temperature of the heater. However, common powdered or blocky fragrances melt and solidify in the heating holes or the inner wall of the diffuser when heated, causing blockage of the air passages, reducing heating efficiency, and affecting temperature control. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a fireproof ceramic aromatherapy burner with adjustable fragrance diffusion, which reduces the sticking of powdered or blocky fragrances after heating and improves heating efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a fireproof ceramic aroma diffuser with adjustable fragrance diffusion, including a ceramic jar and a base. A metal inner liner is in contact with the inside of the ceramic jar. The metal inner liner is flush with the upper end of the ceramic jar. A pressure cap is in contact with the upper end of the metal inner liner. A first groove runs through the bottom of the ceramic jar. A connecting tube is inserted into the first groove. A thermostat is fixedly connected to the bottom end of the connecting tube. A spiral heating ring is fixedly connected to the upper end of the thermostat. The upper end of the spiral heating ring is in contact with the bottom end of the metal inner liner. A temperature sensor is fixedly connected to one side of the metal inner liner. The temperature sensor is connected in series with the thermostat via a wire. A wire is fixedly connected to one side of the thermostat.

[0007] As a preferred technical solution of this utility model, the thermostat is threaded with a pressure ring on the bottom side, and a limit ring is fixedly connected to the upper side of the thermostat. Both the limit ring and the pressure ring are in contact with the bottom of the ceramic tank. By setting the limit ring in conjunction with the pressure ring, the thermostat can be limited, thereby facilitating disassembly and maintenance.

[0008] As a preferred technical solution of this utility model, a heat insulation cover is fixedly connected to the inner wall of the ceramic jar. The heat insulation cover is made of fiberglass material. By setting the heat insulation cover, heat transfer can be reduced, and the problem of burns when handling the jar manually can be reduced.

[0009] As a preferred technical solution of this utility model, an elastic copper sheet is in contact with the upper side of the ceramic jar. The elastic copper sheet is fixedly connected to the upper side of the outer side of the metal inner liner. By setting the elastic copper sheet, friction is increased, which facilitates the stable connection between the metal inner liner and the ceramic jar.

[0010] As a preferred technical solution of this utility model, a retaining ring is fixedly connected to the bottom of the metal inner liner. The retaining ring is located in contact with the spiral heating ring. By setting the retaining ring, the connection effect between the metal inner liner and the ceramic pot can be increased.

[0011] As a preferred technical solution of this utility model, a retaining ring is fixedly connected to the upper end of the metal inner liner, and a heat insulation ring is sleeved on the outer side of the retaining ring. The heat insulation ring is uniformly recessed and is made of rubber material. By setting the heat insulation ring, it is easy to manually detach the metal inner liner from the ceramic jar.

[0012] This utility model has the following advantages: By installing a removable metal inner liner inside the ceramic jar and using a temperature sensor to monitor the temperature, a spiral heating ring is controlled to heat the metal inner liner, thereby controlling the evaporation rate of the aromatherapy material inside the metal inner liner and facilitating the removal and cleaning of the metal inner liner.

[0013] Meanwhile, by setting up heat insulation rings and isolation covers, the heat transfer can be reduced and the air passage blockage can be reduced when the spiral heating ring heats the metal inner liner, thus improving the heating effect. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The fireproof ceramic aroma diffuser with adjustable fragrance diffusion shown includes a ceramic jar 1 and a base 2. A metal inner liner 3 is in contact with the inside of the ceramic jar 1. The metal inner liner 3 is flush with the upper end of the ceramic jar 1. A pressure cap 4 is in contact with the upper end of the metal inner liner 3. The pressure cap 4 has evenly spaced grooves for the diffusion of aroma gas. A first groove 5 passes through the bottom of the ceramic jar 1. A connecting tube 6 is inserted into the first groove 5. A thermostat 8 is fixedly connected to the bottom of the connecting tube 6. A spiral heating ring 7 is fixedly connected to the upper end of the thermostat 8. The upper end of the spiral heating ring 7 is in contact with the bottom end of the metal inner liner 3. A temperature sensor 9 is fixedly connected to one side of the metal inner liner 3. The temperature sensor 9 is connected in series with the thermostat 8 through a wire. A wire is fixedly connected to one side of the thermostat 8.

[0018] The thermostat 8 has a pressure ring 10 threadedly connected to its bottom side, and a limit ring 11 is fixedly connected to its upper side. Both the limit ring 11 and the pressure ring 10 are in contact with the bottom of the ceramic jar 1. By setting the limit ring 11 and the pressure ring 10, the thermostat 8 can be disassembled for maintenance by rotating the pressure ring 10 after the metal inner liner 3 is disassembled.

[0019] The inner wall of the ceramic jar 1 is fixedly connected to a heat insulation cover 16, which is made of fiberglass. By setting the heat insulation cover 16, the heat dissipation of the spiral heating ring 7 to the outer wall of the ceramic jar 1 can be blocked, reducing the problem of burns caused by excessive temperature when the hands are held.

[0020] Among them, the upper side of the ceramic jar 1 is in contact with an elastic copper sheet 14, which is fixedly connected to the upper side of the metal inner liner 3. By setting the elastic copper sheet 14, one end of the elastic copper sheet 14 abuts against the inner wall of the ceramic jar 1, and the metal inner liner 3 can be stably placed inside the ceramic jar 1 by abutting against the inner wall of the metal inner liner 3.

[0021] The metal inner liner 3 is fixedly connected to a retaining ring 12 at its bottom end. The retaining ring 12 is located in contact with the spiral heating ring 7. By setting the retaining ring 12, the stability of the metal inner liner 3 can be improved by abutting against the outermost side of the spiral heating ring 7.

[0022] The metal inner liner 3 is fixedly connected to the upper end of a retaining ring 13, and a heat insulation ring 15 is sleeved on the outside of the retaining ring 13. The heat insulation ring 15 has uniform indentations and is made of rubber. By setting the heat insulation ring 15 and the indentations on the heat insulation ring 15, the friction can be increased, making it easier to disassemble the metal inner liner 3.

[0023] Working principle: To avoid the sticking problem caused by the aromatherapy heating inside the ceramic jar 1, a removable metal inner liner 3 can be used to solve the sticking problem during aromatherapy heating. When sticking occurs or the aromatherapy needs to be replaced, the metal inner liner 3 can be moved upward by pulling the retaining ring 13, so that the spiral heating ring 7 no longer contacts the bottom of the metal inner liner 3. The metal inner liner 3 can also be moved upward by manually pulling the heat insulation ring 15 to avoid the danger caused by excessive temperature. When the temperature sensor 9 detects that the temperature of the metal inner liner 3 is lower than the preset minimum temperature value, the thermostat 8 will control the spiral heating ring 7 to start heating to increase the temperature of the metal inner liner 3. As the spiral heating ring 7 heats up, the temperature of the metal inner liner 3 gradually increases. Temperature sensor 9 continuously monitors the temperature and feeds the signal back to thermostat 8. When the temperature reaches the preset maximum temperature value, thermostat 8 will control the spiral heating ring 7 to stop heating to avoid the aromatherapy from deteriorating or causing safety hazards due to excessive temperature. If, during use, the temperature of the metal inner liner 3 deviates from the preset range due to some reason (such as changes in ambient temperature, changes in the amount of aromatherapy, etc.), thermostat 8 will readjust the working state of the spiral heating ring 7 according to the feedback signal from temperature sensor 9 to maintain the temperature of the metal inner liner 3 within the preset range. The thermostat 8 transmits temperature signals through temperature sensor 9 and performs temperature control, thereby using different temperatures to control the evaporation rate of the aromatherapy.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
