[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0029] First, as Figure 1 as well as Figure 2 As shown, the utility model provides a brewing structure, including a body 1, a water outlet element 2 and a blocking component 3. The body 1 is formed with a plurality of water outlet holes 11 opening downward and an annular retaining bar 12 surrounding the plurality of water outlet holes 11. One end of the water outlet element 2 is mounted on the body 1, and a water channel 21 is provided in the water outlet element 2, and the water channel 21 is connected with the plurality of water outlet holes 11. The blocking component 3 includes a connector 31, a plug 32 and an elastic member 33, the connector 31 is connected with the other end of the water outlet element 2, a stepped hole 311 is provided in the connector 31, and the stepped hole 311 is connected with the water channel 21, the plug 32 and the elastic member 33 are both located in the stepped hole 311, one end of the elastic member 33 abuts against the water outlet element 2, and the other end of the elastic member 33 is connected to the plug 32, and the plug 32 can block the stepped hole 311 under the elastic action of the elastic member 33. Specifically, the elastic member 33 can be a spring.

[0030] In specific application, the plug 32 blocks the stepped hole 311 in the connector 31 under the elastic action of the elastic member 33, so that the water remaining in the water outlet pipe will be heated to become water vapor and cannot flow out through the stepped hole 311, the water channel 21 of the water outlet element 2 and the water outlet hole 11, so that the water vapor will not flow back to the powder outlet or the inside of the grinding assembly, thereby avoiding the situation that the water vapor will cause the powder outlet 32 ​​of the grinding assembly to be blocked or the coffee beans to be wet; when water needs to be injected into the hand brewing pot, the water pump is powered on to pump the cold water in the water tank to the heating element to heat it into hot water and then pump it into the hand brewing pot. Since the water pump accelerates the flow of water, the pressure generated by the water flow can overcome the elastic force of the elastic member 33, so that the plug 32 no longer blocks the stepped hole 311, so that the hot water can flow out and fall into the hand brewing pot through the water outlet pipe connected to the heating element, the stepped hole 311, the water channel 21 of the water outlet element 2 and the water outlet hole 11 in sequence.

[0031] like Figure 3 and Figure 4 As shown, in some preferred embodiments, the body 1 is formed with an open ring-shaped guide plate 13, which is located inside the annular baffle 12, and one end of which is connected to the inner side wall of the annular baffle 12 through a connecting plate 13a. The guide plate 13 and the connecting plate 13a divide the annular baffle 12 into a first space 121 and a second space 122 that are interconnected, and a plurality of water outlets 11 are respectively connected to the first space 121 and the second space 122, and the outlet of the water channel 21 is connected to the first space 121. In specific applications, by arranging the open ring-shaped guide plate 13 inside the annular baffle 12, the hot water that flows into the annular baffle 12 through the water channel 21 can flow out evenly from the plurality of water outlets 11 under the action of the guide plate 13, so that the brewed coffee is more even.

[0032] Specifically, the water channel 21 includes a first channel and a second channel, the first channel is arranged horizontally, and the second channel is arranged longitudinally.

[0033] like Figure 3 and Figure 4 As shown, in some preferred embodiments, a retaining ring 22 is formed on the water outlet element 2, and the height of the retaining ring 22 is less than the height of the guide plate 13. When the water outlet element 2 is installed on the machine body 1, one end of the retaining ring 22 extends into the second space 122 and abuts against the inner wall of the guide plate 13. In specific applications, the retaining ring 22 cooperates with the guide plate 13 to ensure that there is no gap between the guide plate and the water outlet element 2, so that the hot water flowing from the water channel 21 into the annular retaining bar 12 can enter the first space 121 and the second space 122 in sequence under sufficient pressure and then flow out evenly from the multiple water outlet holes 11, which can further improve the uniformity of brewing coffee.

[0034] like Figure 3 and Figure 4As shown, in some preferred embodiments, the water outlet element 2 is formed with a convex strip 23, the height of the convex strip 23 is less than the height of the guide plate 13, and when the water outlet element 2 is installed on the body 1, the convex strip 23 extends into the opening of the guide plate 13 in the shape of an open ring, and abuts against the connecting plate 13a. In specific applications, the shape of the convex strip 23 is adapted to the shape of the connecting plate 13a, and the convex strip 23 cooperates with the connecting plate 13a so that there is no gap between the connecting plate 13a and the water outlet element 2, so as to prevent the hot water entering the annular baffle 12 from passing through the gap between the connecting plate 13a and the water outlet element 2 from the first space 121 to the second space 122, resulting in a reduction in the pressure of the hot water entering the annular baffle 12. Specifically, one end of the convex strip 23 is connected to the outer wall of the baffle ring 22, so that there is no gap between the baffle ring 22 and the convex strip 23.

[0035] like Figure 2 As shown, in some preferred embodiments, one end of the connector 31 extends into the water channel 21, and the outer wall of one end of the connector 31 is sleeved with a first sealing ring 4, and the first sealing ring 4 abuts against the side wall of the water channel 21. In specific applications, by designing one end of the connector 31 to extend into the water channel 21, the connector 31 can be firmly connected to the water outlet element 2, and at the same time, the first sealing ring 4 is sleeved on the outer wall of one end of the connector 31, which can ensure the seal between the connector 31 and the water outlet element 2 to avoid water leakage.

[0036] like Figure 2 As shown, in some preferred embodiments, the outer side wall of one end of the connector 31 is provided with a mounting groove 312, and the first sealing ring 4 is located in the mounting groove 312. In specific applications, by providing the mounting groove 312 that matches the shape of the first sealing ring 4 on the outer side wall of one end of the connector 31, it is not only convenient to install the first sealing ring 4, but also can make the sealing between the connector and the water outlet element 2 better.

[0037] like Figure 2 As shown, in some preferred embodiments, one end of the water outlet element 2 extends into the annular baffle 12, and a second sealing ring 5 is sleeved on the outer wall of one end of the water outlet element 2, and the second sealing ring 5 abuts against the inner wall of the annular baffle 12. In specific applications, the second sealing ring 5 can ensure a firm seal between the water outlet element 2 and the annular baffle 12 to prevent water leakage.

[0038] like Figure 2 As shown, in some preferred embodiments, the diameter of each water outlet hole 11 is gradually reduced from top to bottom. In specific applications, by designing the diameter of each water outlet hole 11 to gradually decrease from top to bottom, the flow rate of hot water flowing out of the water outlet hole 11 is increased, thereby achieving a better brewing effect.

[0039] In a second aspect, the utility model provides a coffee machine, comprising the brewing structure of the first aspect, a water tank, a water pump, a heating element, a water outlet pipe, a grinding assembly and a hand-brewed pot. The water outlet of the water tank is connected to the water inlet of the water pump through a pipeline, the water outlet of the water pump is connected to the water inlet of the heating element through a pipeline, the water inlet of the water outlet pipe is connected to the water outlet of the heating element, the water outlet of the water outlet pipe is connected to the connector 31, the powder outlet of the grinding assembly is located on one side of the multiple water outlet holes 11, and the hand-brewed pot is located below the multiple water outlet holes 11.

[0040] In specific application, the grinding component grinds the coffee beans into coffee powder, and the coffee powder falls into the filter of the hand brewing pot through the powder outlet of the grinding component. The cold water in the water tank enters the heating element under the action of the water pump and is heated into hot water. The hot water is injected into the hand brewing pot through the water outlet pipe and the brewing structure and mixed with the coffee powder to form hot coffee.

[0041] To sum up, in one or more embodiments of the present invention, the brewing structure and the coffee machine of the present invention provide a force to the plug through an elastic member, so that the plug can seal the stepped hole in the connecting head, so that the water vapor generated in the water outlet pipe will not flow out through the water channel of the water outlet element, so as to avoid the water vapor from flowing back to the powder outlet or the interior of the grinding assembly, causing the powder outlet of the grinding assembly to be blocked or the coffee beans to become wet.
