Description

A kind of voice suggestion utensil of infusing tea

Technical field

This practicality relates to a kind of utensil of infusing tea, and is specifically related to a kind ofly adorn the utensil of infusing tea that a bottom is provided with the son cup of filter screen by a female glass holder, and this utensil can separate the tea after brewing with tealeaves.

Background technology

China is a tea culture ancient civilized country, and most of people have the custom of having tea, and the utensil of infusing tea is the indispensable utensil of the person of having tea.Be subjected to the restriction of condition and time, previously infusing tea is directly tealeaves directly to be put into teacup, dashes to brew with hot boiling water again, drinks immediately.Because teacup in the past only is a cylinder barrel, tealeaves in it is soaked in the water constantly, and the person of having tea both had been easy to drink tealeaves, crosses taste of a specified duration because of infusion of tea again and just can become very pained, even best tealeaves also can lose original flavor, order likes the person of having tea to feel puzzlement deeply.

The existing in the prior art solution of the problems referred to above, know the patent scheme of office's on April 26th, 1989 disclosed a kind of " tea-making facility " (Granted publication number for CN2036351U) as state, this scheme " include the child cup that a female cup and can be sleeved on female cup top; Be provided with the filter screen of a projection in this child cup, the bottom surface of son cup has a hole, and this hole is stopped up by a spherical sealing stopper at ordinary times, and the sealing stopper connects outside the son cup with a control line; When making tea, tealeaves and boiling water are put into the son cup earlier, wait for an appropriate time after, when making boiling water brew the suitableeest tea of drinking, the pulling control line is to open the sealing stopper, and tea promptly flows in female cup, tealeaves is then kept somewhere the filter screen top in the son cup, and the phase makes tea separate with tealeaves." as seen; though above-mentioned patented product can make tea separate with tealeaves, avoid drinking person that tealeaves is drunk in the population, but still will grasp soak time; this does not have experience or the busy person of work for those, and above-mentioned puzzlement still can not be removed fully with the person's of having tea memory.

Summary of the invention

In view of there is above-mentioned deficiency in prior art, technical problem to be solved in the utility model provides a kind of utensil of infusing tea with voice suggestion.

The scheme that the utility model solves the problems of the technologies described above is:

A kind of voice suggestion utensil of infusing tea, this utensil comprises that a female cup and can be sleeved on female cup top and be provided with filter screen and the son of one-way cock glass and the bowl cover that is articulated in sub-rim of a cup portion, it is characterized in that described bowl cover is a double-decker, constitute this double-decker and be provided with voice warning circuit between two-layer up and down, this circuit is by be the minimum control module that constitutes of core with single-chip microcomputer (CPU) and being located at temperature sensing unit on the single-chip processor i/o mouth, buzzer, display unit and respectively over the ground the temperature and time of cross-over connection on the single-chip processor i/o mouth model selection button is set, temperature adds and subtracts button is set, time adds and subtracts button and beginning countdown and meter temperature button are set.

The workflow of above-mentioned voice warning circuit is as described below: after powering on, make single-chip microcomputer enter duty, operating time is provided with model selection button or temperature and is provided with that model selection button select time is provided with pattern or temperature is provided with pattern, if select time is provided with pattern, operating time adds and subtracts and button is set timing is set again, operation beginning countdown button promptly begins countdown then, in case regularly finishing described buzzer sends voice suggestion; As select temperature that pattern is set, and operating temperature adds and subtracts button is set again, and operation begins to count the temperature button and promptly begins to count temperature then, in case a temperature is reduced to design temperature in the cup, described buzzer also sends voice suggestion.

In the utility model technique scheme, described single-chip microcomputer (CPU) can be the chip that is integrated with A/D converter, as PIC16F716, can be the chip with A/D function also, as PIC16C54.When described single-chip microcomputer (CPU) is when being integrated with the chip of A/D converter, described temperature sensing unit is made of the pull-up resistor and the drop-down thermistor that are located on the single-chip processor i/o mouth; In order to improve accuracy of detection, described temperature sensing unit also comprises the Voltage Reference reference circuit of a temperature sensing unit, this circuit is the resistance of cross-over connection on the I/O of the single-chip microcomputer mouth formation of connecting with diode over the ground, and described resistance is connected with another I/O mouth of single-chip microcomputer with the tie point of diode.When described single-chip microcomputer (CPU) is when not having the chip of A/D translation function, described temperature sensing unit is made up of thermistor, measuring resistance, discharge resistance and charge and discharge capacitance, wherein, one of the discharge resistance of thermistor, measuring resistance is connected to respectively on the single-chip microcomputer one I/O mouth, the other end is connected to an end of charge and discharge capacitance, and the other end of charge and discharge capacitance is connected with the positive pole of power supply.

In the utility model technique scheme, described temperature setup unit by respectively over the ground two the drop-down buttons of cross-over connection on the single-chip processor i/o mouth constitute, wherein one is provided with button for temperature adds, another is that temperature subtracts button is set; Described time setting unit also by respectively over the ground two the drop-down buttons of cross-over connection on the single-chip processor i/o mouth constitute, wherein one added button is set for the time, another is to subtract the time button is set.In order to economize on resources, described temperature adds and the multiplexing time of button is set adds button is set, and temperature subtracts and the multiplexing time of button is set subtracts button is set, and enters releasing the button of duty in described beginning countdown and the multiplexing minimum control system of meter temperature button.

Technical scheme described in the utility model is designed to double-decker with bowl cover, in its double-decker, voice warning circuit is set, the fiery marquis of immersion is set and gives voice suggestion by this circuit, also setting completed can be engaged in other work relievedly in case brew, can taste original flavor green tea when hearing warm prompting sound, both need not worry to soak and overdo, also not worry not bubbling out tea juice.Because suitable soak time is not only relevant with the kind of the person's of having tea taste and tealeaves, and it is relevant with water temperature and environment temperature, therefore the utility model is for satisfying higher boundary pursuer's needs, adopt two kinds of different patterns that soak time is set, promptly the time is provided with pattern and temperature is provided with pattern.When the person of having tea has the experience memory of soak time, can the employing time pattern be set, both simply also convenient; When needs are pursued higher boundary, can take all factors into consideration water temperature and environment temperature adopts temperature that pattern is set according to the kind of the preference of its taste and tealeaves.
