Description

Technical Field

[0001] This utility model belongs to the field of small household appliance technology, specifically referring to a steam tea maker that can switch between full power and half power. Background Technology

[0002] Steam tea makers have become a popular small appliance among tea lovers because they can evenly heat tea leaves with steam.

[0003] However, current steam tea makers have some shortcomings in actual use, such as:

[0004] 1. Most products only support full power operation in manual heating mode. The water boils and evaporates quickly. If the user does not intervene in time, the water in the kettle can easily boil dry, which may not only damage the heating element, but also pose a safety hazard.

[0005] 2. The aromatic substances and beneficial components in tea need to be slowly extracted under gentle heating. Continuous boiling at full power will over-extract bitter components such as tea polyphenols and caffeine, destroying the aroma of tea and resulting in poor taste of tea soup, failing to achieve the ideal brewing effect of "slow simmering".

[0006] 3. Users need to constantly monitor the tea brewing status, manually time the process, and switch gears in a timely manner. The operation is stressful and prone to errors, making it particularly unsuitable for scenarios where other tasks need to be performed simultaneously.

[0007] To address this issue, a steam tea maker that can switch between full power and half power is proposed. Utility Model Content

[0008] The technical problem this invention aims to solve is that traditional steam tea makers can only operate at full power in manual heating mode, which easily leads to the water drying out, tea leaves being ruined, inconvenient operation, and poor tea quality.

[0009] To achieve the above functions, the technical solution adopted by this utility model is as follows: A steam tea maker that can switch between full power and half power includes a kettle body and a handle fixedly installed on the side wall of the kettle body. A shell is fixedly connected to the lower end of the kettle body. A function panel is fixedly installed on the side wall of the shell. A bushing is fixedly installed on the inner side wall of the shell. A base is fixedly connected to the lower end of the shell. A heating tube for heating the kettle body is snapped between the bushing and the base. A switch that extends through the shell is rotatably installed on the side wall of the bushing. A power selection unit controlled by the switch is installed on the upper end of the base.

[0010] Furthermore, the power selection unit includes a thermostat fixedly mounted on the upper end of the base and electrically connected to the heating element. A controller is fixedly mounted on the upper end of the base between the function panel and the thermostat, and the controller is electrically connected to the function panel, the working indicator light, the switch, the heating element, and the thermostat respectively.

[0011] Furthermore, the controller integrates diodes.

[0012] Furthermore, the rated current range of the diode is 6A-10A.

[0013] Furthermore, the controller is a mechanical rotary switch, which facilitates switching between different power levels.

[0014] Furthermore, two temperature controllers are provided, and a diode is connected in series with one temperature controller to form a series branch, which is connected in parallel with the other temperature controller.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] 1. By selecting the switch to "Manual High Heat" for full-power rapid boiling of water, and then switching to "Manual Low Heat" for slow simmering by diode control to reduce power, the risk of water drying out due to continuous full-power heating is avoided, and the tea leaves are prevented from being overcooked, thus balancing safety and brewing effect.

[0017] 2. By using rectifier diodes in the control circuit, no complex program control or expensive sensors are required. This requires minimal modification to existing products and production lines, achieving a significant functional upgrade at extremely low cost and strong market competitiveness.

[0018] 3. Retains mechanical power settings with clear "high" and "low" indicators, intuitive for users, requiring no special training to operate, and reducing the risk of burning dry due to forgotten operation, making it safer and more convenient to use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] like Figures 1 to 5 As shown, to achieve the above functions, the technical solution adopted by this utility model is as follows: A steam tea maker that can switch between full power and half power includes a kettle body 1 for holding tea. A heat-insulating plastic handle 2 is fixed to the side wall of the kettle body 1 by bolts, which is convenient for users to hold and avoids burns. A cylindrical shell 3 is fixedly connected to the lower end of the kettle body 1 by a flange seal. A high-temperature resistant plastic bushing 7 is fixedly installed on the inner side wall of the shell 3 by a buckle. A function panel 4 (for selecting different tea brewing modes, which will not be described in detail in the prior art) is fixedly installed on the side wall of the shell 3. The lower end of the shell 3 is fixedly connected by bolts. A circular base 9 is fixedly connected to form a stable main structure of the device. A heating element 8 is fixed between the bushing 7 and the base 9 by a snap-fit ​​method. The heating element 8 is made of stainless steel and can directly heat the bottom of the kettle body 1 to generate steam, realizing the tea brewing function. A metal switch 6 is rotatably set on the side wall of the bushing 7. One end of the switch 6 extends through the outside of the shell 3 for easy operation by the user. The upper end of the base 9 is equipped with a power selection unit directly controlled by the switch 6. The switch 6 is designed as a mechanical knob switch, and the gear adjustment is intuitive and convenient. Users can quickly switch between different heating powers without learning.

[0029] like Figures 1 to 5As shown, the specific structure of the power selection unit includes two thermostats 10. The thermostats 10 are fixed to the upper end of the base 9 by bolts and are electrically connected to the heating element 8 through wires to monitor and control the heating temperature. A controller 11 is also fixed to the upper end of the base 9 by bolts. The controller 11 is located between the function panel 4 and the thermostats 10 and is electrically connected to the function panel 4, the working indicator light 5, the switch 6, the heating element 8, and the two thermostats 10 through wires. It can receive the control signal from the switch 6 and coordinate the operation of each component. The controller 11 integrates a rectifier diode with a rated current of 10A (which can be flexibly selected according to the actual power requirements of the heating element 8, with a selectable range of 6A-10A). The diode is connected in series with one of the thermostats 10 to form a series branch. This series branch is then connected in parallel with the other thermostat 10 without the diode connected in series. Through this circuit design, stable switching between full power and half power can be achieved to meet the needs of different tea brewing scenarios, and the temperature can be regulated by the thermostats 10.

[0030] The specific operating procedures for different gears are as follows:

[0031] 1. Manual high heat setting (full power rapid heating)

[0032] Users can switch to the "manual high heat" setting by rotating the mechanical knob switch. At this time, the contact corresponding to the "full power" setting inside the switch closes with the contact of the thermostat without a rectifier diode connected in series, forming a control circuit of "power supply → switch → thermostat without diode connected in series → heating element → power supply". After the circuit is connected, 220V AC power is directly applied to the heating element, which operates at 100% of its rated power (e.g., 1800W). The heating element heats the kettle body through heat transfer from the bottom, quickly raising the water temperature inside the kettle to meet the need for rapid boiling.

[0033] 2. Manual low heat setting (half power slow cooker)

[0034] Users can switch to the "manual low heat" setting by rotating the mechanical knob switch. At this time, the contact corresponding to "manual low heat" inside the switch closes with the thermostat contact of the series rectifier diode, forming a control circuit of "power supply → switch → thermostat of series diode → rectifier diode → heating element → power supply". The AC power is applied to the heating element after half-wave rectification by the diode. The heating element operates at 50% of its rated power (e.g., 900W) and heats the kettle body through a smooth heat output, maintaining the water temperature at a gentle boil, which is suitable for slow simmering scenarios.

[0035] 3. Automatic water boiling mode (intelligently heats to boiling)

[0036] Users can switch to the "automatic boiling" setting by rotating the mechanical knob switch. At this time, the contact corresponding to "automatic boiling" inside the switch closes with the linkage contact of the controller, temperature sensor and dual thermostat, forming a control circuit of "power supply → switch → controller → temperature sensor → dual thermostat → heating element → power supply". In the initial stage, the controller drives the heating element to heat at full power, and the temperature sensor monitors the water temperature in real time. When the water temperature reaches 100℃ (boiling) and remains so for 3-5 seconds, the controller triggers the thermostat to disconnect the full power path, stop heating, and complete the automatic boiling process, achieving precise heating of the kettle.

[0037] 4. 55-degree heat preservation setting (constant temperature heat preservation)

[0038] Users can switch to the "55°C keep warm" setting by rotating the mechanical knob switch. At this time, the internal contacts of the switch corresponding to "55°C keep warm" close with the contacts of the low-power constant temperature circuit, the keep warm thermostat, and the temperature sensor, forming a control circuit of "power supply → switch → controller → keep warm thermostat → temperature sensor → low-power heating circuit → heating element → power supply". When the water temperature is below 52°C, the circuit is turned on, and the heating element heats the kettle body briefly at low power (e.g., 300W). When the water temperature rises back to 55°C, the thermostat disconnects the circuit and stops heating. Through the intermittent operation of the heating element, the water temperature in the kettle is maintained stably in the range of 53-57°C.
