Description

Technical Field

[0001] The utility model belongs to the technical field of coffee machines, and in particular relates to a pipeline stop valve dripping gas coffee machine. Background Art

[0002] With the improvement of people's living standards, coffee drinks have become popular and have become an indispensable drink in people's daily life. The current methods of making coffee drinks mainly include: brewing with instant coffee, brewing with existing coffee powder in a coffee machine, and using a coffee machine to grind coffee beans and further brew.

[0003] Currently, coffee machines on the market usually use the brewing head on the top to brew the coffee powder in the coffee funnel with hot water, and then the coffee liquid drips into the coffee pot through the coffee liquid outlet below the coffee funnel. When brewing, the existing coffee machines obtain hot water through a heating mechanism and a water tank provided in the coffee machine. During the heating process of the heating mechanism, the water tank injects cold water into the heating mechanism for heating. When the water is heated to the set temperature, the heating mechanism stops working and keeps the water warm. Once the hot water in the heating mechanism is reduced, the cold water in the water tank enters the heating mechanism, causing the water temperature to drop. At this time, the heating mechanism will restart to heat the water until the water temperature reaches the preset value.

[0004] During brewing, the hot water in the hot water mechanism is continuously input into the coffee funnel. At this time, due to the reduction of hot water in the heating mechanism, the water tank will continuously replenish cold water into the heating mechanism, which will cause the water temperature in the heating mechanism to drop, so that the heating mechanism in the coffee machine will restart to heat and maintain the water temperature in the heating mechanism. This will result in a large amount of unused hot water in the coffee machine after brewing is completed, and the above action needs to be repeated to heat the water in the heating mechanism during the next brewing, which will cause energy waste. Utility Model Content

[0005] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a pipeline stop valve drip gas coffee machine, which solves the problem that in the existing coffee machine, in order to maintain the brewing effect during the brewing process of coffee powder, the coffee machine needs to continuously heat the water to maintain the temperature, thereby resulting in a large amount of heated hot water not being used after the brewing is completed, causing energy waste.

[0006] The objectives of the utility model can be achieved through the following technical solutions: a pipeline stop valve drip gas coffee machine, comprising a coffee machine body and a heating mechanism, a water stop valve, a cold water tank, a coffee powder tank, a drip mechanism and a water supply pipe arranged in the coffee machine body, a water outlet is opened at the bottom of the cold water tank and is connected to the heating mechanism, the water outlet end of the heating mechanism is connected to the water supply pipe, the water outlet end of the water supply pipe is connected to the coffee powder tank, the drip mechanism is installed at the bottom of the coffee powder tank and blocks the coffee powder tank, the water stop valve is installed at the water outlet, and when the water pressure in the heating mechanism is greater than or equal to the water pressure in the cold water tank, the water stop valve blocks the water outlet.

[0007] As an optimal technical solution of the present invention, the water stop valve includes a valve core and a valve body. The valve body is fitted on the water outlet. A stepped hole is provided on the bottom surface of the valve body. The valve core is composed of a stepped shaft. The valve core slides in the stepped hole, and the stepped shaft corresponds to the stepped hole.

[0008] As an optimal technical solution of the present invention, the heating mechanism includes a heating tube and a burner. The burner is installed at the bottom of the coffee machine body. The heating tube is mounted above the burner and is connected to the water supply pipe and the water outlet respectively.

[0009] As a preferred technical solution of the present invention, an insulation layer is wrapped around one end of the heating pipe close to the water outlet.

[0010] As a preferred technical solution of the present invention, the drip mechanism includes a water outlet switch, a sealing plate and a water outlet spring. The middle part of the water outlet switch is rotatably connected to the coffee machine body, and one end abuts against the sealing plate. The sealing plate is rotatably connected to the bottom of the coffee powder trough, and the end away from the water outlet switch abuts against the water outlet spring. The top of the water outlet spring is connected to one side of the bottom surface of the coffee powder trough, and the sealing plate blocks the water outlet end of the coffee powder trough.

[0011] As a preferred technical solution of the present invention, a rubber plug is provided in the middle of the sealing plate, and the rubber plug is slidably fitted with the water outlet end of the coffee powder tank.

[0012] The beneficial effects of the present invention are as follows: a water stop valve is provided at the water outlet connected to the heating mechanism and the cold water tank, so that the water stop valve controls the on and off of the water outlet according to the water pressure in the cold water tank and the heating mechanism.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-4The present embodiment provides a pipeline stop valve drip gas coffee machine, comprising a coffee machine body 1 and a heating mechanism 2, a water stop valve 3, a cold water tank 4, a coffee powder tank 5, a drip mechanism 6 and a water supply pipe 7 arranged in the coffee machine body 1. A water outlet is provided at the bottom of the cold water tank 4 and is connected to the heating mechanism 2. The water outlet end of the heating mechanism 2 is connected to the water supply pipe 7, and the water outlet end of the water supply pipe 7 is connected to the coffee powder tank 5. The drip mechanism 6 is installed at the bottom of the coffee powder tank 5 and blocks the coffee powder tank 5. The water stop valve 3 is installed at the water outlet. When the water pressure in the heating mechanism 2 is greater than or equal to the water pressure in the cold water tank 4, the water stop valve 3 blocks the water outlet. When the coffee machine is used, during the process of filling water into the cold water tank 4, the water pressure in the cold water tank 4 will continue to increase, thereby causing the water stop valve 3 to open the water outlet to replenish water into the heating mechanism 2. When the water pressure in the heating mechanism 2 is the same as the water pressure in the cold water tank 4, the water stop valve 3 will close the water outlet. When the heating mechanism 2 is heating, the water pressure in the heating mechanism 2 will continue to increase, thereby ensuring that the water stop valve 3 can firmly close the water outlet, thereby ensuring that the cold water in the cold water tank 4 will not enter the heating mechanism 2 for repeated heating during the heating process of the heating mechanism 2. When the heating of the heating mechanism 2 is completed, the valve of the water supply pipe 7 is opened to allow the water supply pipe 7 to transport the hot water heated in the heating mechanism 2 to the coffee powder tank 5 to mix and dissolve the coffee powder in the coffee powder tank 5 to obtain coffee. In the mixing process, the drip mechanism 6 can block the coffee powder tank 5 to avoid pouring out the coffee liquid before the coffee powder is completely dissolved, resulting in poor brewing effect.

[0022] Moreover, during the heating process, since the water outlet and the water supply pipe 7 are both in a closed state, the water pressure in the heating mechanism 2 will continue to increase. Once the water supply pipe 7 is opened, the hot water in the heating mechanism 2 will directly enter the coffee powder tank 5 with low pressure under the action of pressure to complete the brewing. When the hot water in the heating mechanism 2 is poured into the coffee powder tank 5 by the water supply pipe 7 being opened, the coffee powder tank 5 and the space in the heating mechanism 2 are connected to form a whole. At the same time, the hot water in the heating mechanism 2 enters the coffee powder tank 5, filling the space in the coffee powder tank 5. The pressure in the coffee powder tank 5 is increased due to the high temperature of the hot water. Moreover, since the temperature of the entire space is much higher than the temperature in the cold water tank 4, the pressure in the entire space will be The pressure at the water outlet of the coffee machine 2 is greater than that in the cold water tank 4, thereby ensuring that the cold water in the cold water tank 4 does not enter the heating mechanism 2 for repeated heating during the heating and brewing stages, thereby wasting energy. When brewing is completed, the water supply pipe 7 is closed. At this time, the hot water in the heating mechanism 2 has entered the coffee powder tank 5 and the spatial connection with the coffee powder tank 5 is cut off. Therefore, the pressure provided by the remaining hot water in the heating mechanism 2 at this time will gradually decrease as the temperature decreases, resulting in the pressure in the heating mechanism 2 being lower than the pressure in the cold water tank 4. At this time, the water stop valve 3 opens the water outlet under the pressure in the cold water tank 4 to fill the heating mechanism 2 with cold water until the pressure in the heating mechanism 2 is the same as that in the cold water tank 4, and the water stop valve 3 is closed at the same time. The above process is repeated continuously to complete brewing.

[0023] The closure 321 of the water tank 4 is provided with a plurality of springs, and the closure 321 of the water tank 4 is provided with a plurality of springs, and the closure 321 of the water tank 4 is provided with a plurality of springs. When the water in the cold water tank 4 is filled with cold water, the pressure in the water tank 4 will be increased, and the pressure in the water tank 4 will be increased. ...

[0024] In order to better heat the cold water and complete the brewing, in one embodiment, the heating mechanism 2 includes a heating tube 21 and a burner 22. The burner 22 is installed at the bottom of the coffee machine body 1. The heating tube 21 is mounted above the burner 22 and is connected to the water supply pipe 7 and the water outlet respectively. When heating is required, the burner 22 is used to heat the heating tube 21, so that the water in the heating tube 21 and the water supply pipe 7 is heated, and the pressure of the water in the pipe is continuously increased during the heating process. After the water supply pipe 7 is opened, the pressure in the coffee powder tank 5 is lower than the pressure in the hot water pipe. Therefore, the hot water in the hot water pipe will directly enter the coffee powder tank 5 to complete the brewing.

[0025] Since one end of the hot water pipe is located at the bottom of the cold water tank 4, in order to prevent the cold water in the cold water tank 4 from continuously dissipating heat to the hot water pipe when the burner 22 is heating, thereby affecting and reducing the heating efficiency of the burner 22, in one embodiment, an insulation layer 23 is wrapped around the end of the heating tube 21 near the water outlet. By wrapping the insulation layer 23 around the end of the heating tube 21 near the water outlet, the heat dissipation efficiency of the heating tube 21 is reduced, thereby reducing the rate of heat damage to the heating tube 21 during the heating process, and improving the heating efficiency of the burner 22 on the heating tube 21.

[0026] In order to prevent hot water from flowing out of the coffee powder tank 5 during the brewing process, which would result in a poor brewing effect, in one embodiment, the drip mechanism 6 includes a water outlet switch 61, a blocking plate 62 and a water outlet spring 63. The middle part of the water outlet switch 61 is rotatably connected to the coffee machine body 1, and one end abuts against the blocking plate 62. The blocking plate 62 is rotatably connected to the bottom of the coffee powder tank 5, and the end away from the water outlet switch 61 abuts against the water outlet spring 63. The top of the water outlet spring 63 is connected to one side of the bottom surface of the coffee powder tank 5. The blocking plate 62 blocks the water outlet end of the coffee powder tank 5. During the brewing process, the water outlet spring 63 will push one end of the blocking plate 62 to bring the blocking plate 62 close to the water outlet switch. One side of the switch 61 maintains a tendency to rotate upward, thereby completing the blockage of the water outlet end of the coffee powder trough 5, allowing the coffee liquid that has not been completely brewed in the coffee powder trough 5 to flow out, resulting in a poor brewing effect. When brewing is completed, the coffee container is allowed to touch the end of the water outlet switch 61 that is not in contact with the blocking plate 62, and the water outlet switch 61 is allowed to rotate, so that the end of the water outlet switch 61 that is in contact with the blocking plate 62 is rotated downward to allow the blocking plate 62 to deflect downward, thereby releasing the blockage of the coffee powder trough 5 and allowing the coffee liquid in the coffee powder trough 5 to flow out for drinking. Once the coffee container leaves the water outlet switch 61, the blocking plate 62 re-blocks the coffee powder trough 5 under the left and right of the water outlet spring 63.

[0027] In order to better seal the coffee powder trough 5, in one embodiment, a rubber plug 621 is provided in the middle of the sealing plate 62, and the rubber plug 621 is slidably fitted with the water outlet end of the coffee powder trough 5. By providing the rubber plug 621 in the middle of the sealing plate 62, the soft material of the rubber plug 621 can better fit the water outlet end of the coffee powder trough 5 to perform sealing, thereby preventing the high-pressure hot water in the hot water pipe from directly rushing into the coffee powder trough 5 and causing gaps in the sealing of the sealing plate 62 to cause hot water to flow out.
