[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, the present invention is improved on the basis of the prior art latte cup, and the latte cup includes a cup cover assembly 100, an inner liner assembly 200, a cup body assembly 300 and a milk foam ring assembly 400.

[0031] The cup cover assembly 100 includes a cup cover 1, a magnet 17, a pressure cover and a handle. The cup cover 1 is provided with an internal thread, and the pressure cover is installed on the cup cover 1 for opening and closing the cup cover to meet the purpose of drinking or pouring water. The handle is movably installed on the cup cover 1 for hand-carrying operation. The magnet 17 is installed in the center of the cup cover 1. The milk bubble ring assembly 400 adopts a magnetic suspension design, so it can be adsorbed on the cup cover 1 when not in use.

[0032] The cup body assembly 300 includes an outer cup body 11, a silicone sleeve, an anti-skid mat, a light guide column 12 and an adhesive backing 13. A light guide hole and a touch area 11.2 are provided on the cup wall of the outer cup body 11, and an external thread for connecting the cup cover 1 is provided at the cup mouth. The light guide column 12 is adhered to the inner wall of the outer cup body 11 through the adhesive backing 13 and inserted into the light guide hole. The silicone sleeve is mounted on the outer wall of the outer cup body 11 for heat insulation and gripping. The anti-skid mat is provided at the bottom of the outer cup body 11. A drain port 11.1 is provided at the bottom of the outer cup body 11 to avoid water accumulation inside.

[0033] The liner assembly 200 includes an liner cup 3 installed in the outer cup body 11, an insulation seat 4 installed at the bottom of the liner cup 3, and a key module and a drive module installed on the insulation seat 4. The liner cup 3 is made of metal and a heating element is arranged at the bottom to establish heat conduction. The key module generates an electrical signal when the touch area 11.2 is touched. As an improvement, the key module includes a control panel 5, a key display panel 6 and a display panel end cover 8. The heating element and the drive module are electrically connected to the control panel 5, and the key display panel 6 is electrically connected to the control panel 5, and it has light sources representing different modes respectively, and the light sources correspond to the light guide holes one by one to facilitate the conduction of light. A central rod 3.2 is arranged at the center of the bottom of the liner cup 3. When making milk foam, the milk foam ring assembly 400 is installed on the central rod 3.2, and rotates under the magnetic drive of the drive module to realize the milk foaming function. The milk foam ring assembly 400 is a prior art, so it is not repeated.

[0034] The control panel 5 is installed at the bottom of the insulation seat 4, and the key display panel 6 is arranged on the control panel 5. The insulation seat 4 is provided with a mounting groove 4.1. The display panel end cover 8 is fixed on the front side of the mounting groove 4.1 to form a receiving cavity, and the key display panel 6 is arranged in the receiving cavity.

[0035] Since the display panel end cover 8 is provided with a first light hole 8.1, water is easily infiltrated into the first light hole 8.1 if it is not waterproofed, and the connection end of the key spring on the key display panel 6 is easily affected by the water and fails. Therefore, the key display panel 6 must be waterproofed to avoid the above situation. The present invention adopts the following specific means to achieve:

[0036] Method 1: A waterproof paint layer is provided on the surface of the key display panel 6, that is, the front and back surfaces of the key display panel 6 are painted with a three-proof paint to form a waterproof paint layer, thereby achieving overall waterproofing.

[0037] Means 2: A glue hole connected to the receiving cavity is provided on the top side of the display panel end cover 8, and the receiving cavity is filled with sealant that wraps the key display panel 6 through the glue hole. The key display panel 6 is integrally encapsulated by the sealant to achieve waterproofing.

[0038] Means three: The key module further includes an inner sponge pad 7, which is pressed between the display panel end cover 8 and the key display panel 6, and the inner sponge pad 7 is provided with a second light hole corresponding to the first light hole 8.1. The inner sponge pad 7 can seal the inner end of the first light hole 8.1 of the display panel end cover 8 to achieve waterproofing.

[0039] Means 4: The key module further includes a light-distributing film 9, which is arranged outside the display panel end cover 8 and covers the first light-through hole 8.1 of the display panel end cover 8. The light-distributing film 9 can seal the outer end of the first light-through hole 8.1 to achieve a waterproof function, and can also improve the problem of scattered light and make the light more uniform.

[0040] Means 5: The key module further includes an outer sponge pad 10, which is pressed between the display panel end cover 8 and the outer cup body 11, and is provided with a third light hole corresponding to the first light hole 8.1. The outer sponge pad 10 can seal the outer end of the first light hole 8.1 of the display panel end cover 8 to achieve waterproofing.

[0041] Obviously, means one to five can be implemented separately, or some or all of them can be implemented together to achieve the purpose of multiple protection and achieve the best waterproof effect.

[0042] In addition to waterproofing the key module, the present invention also waterproofs the assembly of the connection between the outer cup body 11 and the cup mouth of the inner cup 3, and the specific means are: Figure 2 and 6 As shown, the cup cover assembly 100 includes a sealing ring 2, and the cup mouth of the inner cup 3 is provided with a downwardly folded edge 3.1 and a ring groove 3.3 is formed on the inner side thereof, and the sealing ring 2 is sleeved in the ring groove 3.3.

[0043] The top end face of the cup mouth of the outer cup body 11 is provided with a circle of sealing stopper 11.3. After the outer cup body 11 is connected with the inner cup 3, the sealing stopper 11.3 squeezes the sealing ring 2 to form a sealing isolation on both sides of the sealing stopper 11.3. The lower edge of the folded edge 3.1 just abuts against the top end face of the cup mouth of the outer cup body 11 to form a cup mouth positioning.

[0044] In order to make the present invention have more functions, it is necessary to effectively monitor the liquid temperature at different parts, and the liner assembly 200 also includes a cup wall NTC module 15 and a cup bottom NTC module 16. The cup wall NTC module 15 is attached to 1 / 3 to 1 / 2 of the outer wall of the liner cup 3, and the cup bottom NTC module 16 is attached to the bottom of the liner cup 3. The cup wall NTC module 15 and the cup bottom NTC module 16 are both connected to the control board 5.

[0045] The present invention provides three modes, which are as follows:

[0046] Milk froth mode: The NTC module is used to collect the liquid temperature to determine whether heating is required. If the temperature is lower than 50-60℃, which is the best temperature for frothing milk, it is necessary to heat the milk first and then froth it. When heating, to prevent the bottom from getting sticky, we also start the milk froth ring assembly 400 at a low speed, which can heat the liquid evenly. When the liquid temperature is detected to reach 50-60℃, the motor switches to high-speed frothing for 1 minute. Frothing milk at a low speed first and then at a high speed effectively improves the fineness of the froth. If the temperature is higher than 70℃, frothing milk is not allowed. At this time, the temperature is too high and the milk froth effect is poor, which effectively reduces the chance of scalding users.

[0047] Stirring mode: The NTC module collects the liquid temperature to determine whether stirring is allowed. If the water temperature is higher than 80℃, high-speed stirring is not allowed. At this time, it can only be stirred slowly. When the NTC detects that the temperature is lower than 50℃, it will automatically switch to high-speed stirring, effectively preventing scalding of users.

[0048] Warm milk mode: The liquid temperature is collected through the NTC module to determine whether the liquid needs to be heated. When the temperature is lower than 50±5℃, the heating and slow stirring functions are started. When the liquid is heated to 50℃, the heating and stirring are stopped. When the liquid temperature is lower than 40℃, the heating and stirring are started. This insulation function lasts for 24 hours.
