DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0023] like Figures 1 to 5 The liquid outlet and pressurization structure of a coffee machine shown in the figure is characterized in that it includes: an upper shell 1, a lower shell 2 is installed below the upper shell 1, a powder chamber 3 and a pressurization chamber 4 are respectively provided in the lower shell 2, a filter screen 21 is provided on the powder chamber 3, a through hole 11 is provided in the middle of the pressurization chamber 4, a liquid containing chamber 5 is provided below the pressurization chamber 4, a one-way valve elastic member 6 is fixedly provided on the upper shell 1, a water outlet pipe 7 is connected to one end of the one-way valve elastic member 6, a diverter portion 8 that can be connected to the one-way valve elastic member 6 is fixedly provided in the lower shell 2, a one-way valve core 9 is provided in the one-way valve elastic member 6, and a discharge device 10 is provided in communication with the liquid containing chamber 5 below.
[0024] The above structure is a coffee machine liquid outlet pressurization structure. When in use, water enters from the water outlet pipe 7, pushes the one-way valve core 9 to enter the diverter 8, and the diverter 8 breaks up the water, so that the water enters the powder chamber 3 in a broken state and extracts the coffee powder. After the extraction is completed, the coffee liquid falls into the pressurization chamber 4. Since the pressurization chamber 4 has only one through hole 11, part of the coffee liquid will accumulate in the pressurization chamber 4 to increase the pressure; due to the fast water flow, part of the coffee liquid is not discharged in time and accumulates in the liquid chamber 5, thereby increasing the pressure and impacting the liquid discharge device 10, thereby forming a passage to discharge the coffee liquid. Later, the amount of coffee liquid is reduced and cannot impact the liquid discharge device 10, so the remaining coffee liquid naturally cannot be discharged, avoiding the dripping phenomenon of the ordinary coffee machine. Compared with the prior art, the secondary pressurization structure is provided to achieve the technical effect of increasing the coffee extraction pressure. At the same time, the secondary pressurization structure also has the function of sealing the liquid outlet. After the coffee machine completes the coffee extraction work, the subsequent coffee tail liquid cannot pass through the secondary pressurization structure due to insufficient liquid outlet pressure, and will not drip from the coffee machine.
[0025] like Figure 3 As shown, in some embodiments of the utility model, the one-way valve elastic member 6 includes a valve body 61 fixed on the upper shell 1, and a fixing seat 62 is symmetrically fixed on the valve body 61. The valve body 61 is fixed to the upper shell 1 through the fixing seat 62. The water outlet pipe 7 is connected to the input end of the valve body 61. The user installs the fixing seat 62 on the upper shell 1 through bolts, so that the valve body 61 is installed on the upper shell 1. At this time, the water outlet pipe 7 and the diversion part 8 are connected to the valve body 61.
[0026] like Figure 2 As shown, in some embodiments of the utility model, the diverter portion 8 includes a diverter chamber 81 fixedly arranged above the lower shell body 2, a bolt column 82 is installed and fixed in the diverter chamber 81, and a diverter 83 is fixed below the bolt column 82 and above the powder chamber 3. The diverter chamber 81 is connected to the output end of the valve body 61. When the water flows through the valve body 61 to the diverter chamber 81, the water source is dispersed through the multiple holes on the diverter 83 at this time, so that the water source enters the powder chamber 3 in a dispersed state for extraction, and the water source impacts the protrusion of the bolt column 82, so that part of the water flow is dispersed, reducing the pressure of the separator 83.
[0027] like Figure 5As shown, in some embodiments of the utility model, the one-way valve core 9 includes a flow pipe 91 arranged in the valve body 61, a narrow flow opening 92 is provided on the right side of the flow pipe 91, a seal 93 is movably inserted in the flow pipe 91, and a spring 94 is fixed in the flow pipe 91. When the water source flows through the water pipe 7 to the narrow flow opening 92 provided on the right side of the flow pipe 91, the water source moves the seal 93 along the flow pipe 91, so that a gap is generated between the seal 93 and the narrow flow opening 92, allowing the water source to flow from the flow pipe 91 to the diversion part 8. When the water flow stops being transported, the seal 93 is reset by the spring 94, so that the seal 93 and the narrow flow opening 92 are sealed with each other.
[0028] like Figure 4 As shown, in some embodiments of the present utility model, the liquid discharge device 10 includes a first liquid discharge port 101 arranged below the lower shell 2 and connected to the liquid containing chamber 5, an elastic support seat 102 is arranged in the first liquid discharge port 101, a first pressurizing elastic member 103 is sleeved above the elastic support seat 102, a pressurizing resistor 104 is arranged at the liquid outlet end above the first liquid discharge port 101, the first pressurizing elastic member 103 is arranged between the pressurizing resistor 104 and the elastic support seat 102, and second liquid discharge ports 111 are arranged on the left and right sides of the elastic support seat 102. The extracted coffee liquid accumulates in the pressurizing chamber 4 to increase the pressure. Due to the fast water flow, part of the coffee liquid is not discharged in time and accumulates in The pressure in the liquid-containing chamber 5 is increased, and then the pressure is increased to impact the boost resistor 104, so that the boost resistor 104 moves downward along the first liquid discharge port 101. At this time, the liquid outlet end above the first liquid discharge port 101 is separated from the boost resistor 104, so that the first liquid discharge port 101 forms a channel, and the coffee liquid is discharged from the first liquid discharge port 101 and the second liquid discharge port 111. Later, the amount of coffee liquid is reduced and cannot impact the plug. At this time, the first boost elastic member 103 arranged between the boost resistor 104 and the elastic support seat 102 drives the boost resistor 104 to move to the liquid outlet end above the first liquid discharge port 101 and seal it. The remaining coffee liquid naturally cannot be discharged, thereby avoiding the dripping phenomenon of ordinary coffee machines and achieving the effect of secondary pressurization.
[0029] like Figure 4As shown, in some embodiments of the present invention, a guide column 105 is provided below the pressure-boosting resistor 104, a placement groove 106 is provided at the bottom of the guide column 105, a second pressure-boosting elastic member 107 is provided in the placement groove 106, a guide member 108 is fixedly provided above the elastic support seat 102, the placement groove 106 is guided and plugged on the guide member 108, and the second pressure-boosting elastic member 107 is arranged between the guide member 108 and the placement groove 106. When the coffee liquid is not discharged in time and accumulates in the liquid containing chamber 5 to generate pressure, the pressure hits the pressure-boosting resistor 104. At this time, the boost resistor 104 moves downward through the guide column 105 along the guide member 108 fixed above the elastic support seat 102, so that the first liquid discharge port 101 forms a channel, and the coffee liquid is discharged from the first liquid discharge port 101 and the second liquid discharge port 111. Later, the amount of coffee liquid is reduced and cannot impact the plug. At this time, the second boost elastic member 107 provided in the placement groove 106 drives the boost resistor 104 to move upward to reset and seal the liquid outlet end above the first liquid discharge port 101. Then the remaining coffee liquid cannot be discharged naturally, avoiding the dripping phenomenon of ordinary coffee machines and achieving the effect of secondary pressurization.
[0030] like Figure 4 As shown, in some embodiments of the present invention, a first magnetic attraction 109 is embedded in the outer wall of the placement groove 106, and a second magnetic attraction 110 is fixedly mounted on the guide member 108. When the coffee liquid has not been discharged in time and accumulates in the liquid containing chamber 5 to generate pressure, the pressure hits the boost resistor 104. At this time, the boost resistor 104 moves downward along the elastic support seat 102, so that the first liquid discharge port 101 forms a channel, and the coffee liquid is discharged from the first liquid discharge port 101 and the second liquid discharge port 111. Later, the amount of coffee liquid is reduced and cannot impact the plug. The first magnetic attraction 109 embedded in the outer wall of the placement groove 106 and the second magnetic attraction 110 fixedly mounted on the guide member 108 approach each other and generate a repulsive force, so that the boost resistor 104 rebounds upward and resets.
