[0002] With the continuous improvement of social level, people's pursuit of quality of life is also getting higher and higher, and coffee has become a very popular drink in daily life. Generally, people make coffee through coffee machines in daily life.

[0003] In the existing coffee machines, water is generally injected from a water tank into the heating system of the coffee machine. However, during the process of water quickly entering the heating system of the coffee machine, the pressure in the heating system cannot be released in time, which easily causes damage to the equipment and reduces the service life of the coffee machine. Summary of the Utility Model

[0004] In order to solve the technical problems in the background art, the utility model provides a rapid water filling and pressure relief valve.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A rapid water filling and pressure relief valve includes a valve body, a pressure relief valve block group and a water outlet slider slidably arranged in the valve body. A water storage cavity is formed in the valve body, a water injection channel is formed at the end of the valve body, and a water outlet channel and a pressure relief channel are sequentially arranged on the side of the valve body along the water flow direction;

[0007] Water enters the water storage cavity along the water injection channel and applies a certain acting force to the water outlet slider. The acting force at least includes a first pressure and a second pressure. When the water outlet slider bears the first pressure, the water outlet slider slides and a water passing gap communicating the water storage cavity and the water outlet channel is formed between the water outlet slider and the inner wall of the valve body. When the water outlet slider bears the second pressure, the water outlet slider abuts and forces the pressure relief valve block group to slide to communicate the water storage cavity and the pressure relief channel.

[0008] Preferably, the water outlet slider is floatingly arranged on the pressure relief valve block group, and in the initial state, the water outlet slider closes the water outlet channel, and the pressure relief valve block group closes the pressure relief channel. When the pressure borne by the water outlet slider is greater than or equal to the first pressure and less than the second pressure, the water outlet slider slides down and connects the water storage cavity and the water outlet channel. When the pressure borne by the water outlet slider is greater than or equal to the second pressure, the water outlet slider drives the pressure relief valve block group to descend, and synchronously connects the water storage cavity to the water outlet channel and the pressure relief channel. Through the above improvement, the first pressure is the normal water injection pressure. When the pressure borne by the water outlet slider is greater than or equal to the first pressure and less than the second pressure, the water outlet slider slides down and connects the water storage cavity and the water outlet channel to quickly fill water. The second pressure is the overload pressure. When the pressure borne by the water outlet slider is greater than or equal to the second pressure, the water outlet slider drives the pressure relief valve block group to descend, and synchronously connects the water storage cavity to the water outlet channel and the pressure relief channel to relieve pressure and return the internal pressure to the normal level.

[0009] Preferably, an arc-shaped inclined surface is formed on the water outlet slider, and a water outlet inclined surface is formed in the valve body. When the arc-shaped inclined surface is in contact with the water outlet inclined surface, the valve body is in a water-closed state. When the arc-shaped inclined surface is away from the water outlet inclined surface and forms a water passing gap to connect the water storage cavity and the water outlet channel, the valve body is in a water-passing state. Through the above improvement, the water outlet slider is integrally arranged in an arc shape and fits the inner wall of the valve body. As the water outlet slider is subjected to the pressure of the water in the water injection channel, the water outlet slider will slide down, causing the arc-shaped inclined surface on the water outlet slider to be away from the water outlet inclined surface on the valve body to form a water passing gap, so that water can be discharged through the water passing gap to realize water filling for the coffee machine.

[0010] Preferably, a sliding rod is formed at the bottom of the water outlet slider, a sliding groove for the sliding rod to be inserted is formed on the pressure relief valve block group, and a first elastic element is sleeved on the sliding rod. One end of the first elastic element abuts against the pressure relief valve block group, and the other end abuts against the water outlet slider, so that the water outlet slider always has an upward movement tendency. Through the above improvement, the cooperation of the sliding rod and the sliding groove is used to greatly improve the stability of the water outlet slider during the sliding process. And when the pressure generated by the water on the water outlet slider is greater than the acting force of the first elastic element, the water outlet slider will slide down to fill water. And when the pressure of the water on the water outlet slider is less than the pressure of the second elastic element, the water outlet slider will reset, so that the arc-shaped inclined surface fits the water outlet inclined surface and the valve body is in a water-closed state.

[0011] Preferably, a limiting convex block is formed on the inner wall of the valve body, and a limiting groove for the limiting convex part to be inserted is formed on the water outlet slider. Through the above improvement, the cooperation of the limiting convex part and the limiting groove is used to prevent the water outlet slider from rotating during the sliding process.

[0012] Preferably, the pressure relief valve block group includes a sliding part slidably disposed in the valve body, a contact part placed in the sliding part, and a second elastic element disposed at the bottom of the sliding part. One end of the second elastic element abuts against the valve body, and the other end abuts against the sliding part. The water outlet slider presses downward on the contact part, causing the sliding part to slide downward and exposing the pressure relief channel to connect the water storage cavity and the pressure relief channel. Through the above improvement, when the pressure received by the water outlet slider is the second pressure, the water outlet slider first slides downward to connect the water storage cavity and the water outlet channel, and continues to slide downward to abut against the contact part, so that the water outlet slider drives the sliding part to continue to slide downward, exposing the pressure relief channel and connecting it to the water storage cavity for pressure relief. When the pressure drops below the second pressure, the second elastic element drives the sliding part to move upward to cut off the connection between the water storage cavity and the pressure relief channel to stop pressure relief, ensuring the water filling speed.

[0013] Preferably, a first contact inclined surface is formed on the water outlet slider, and a second contact inclined surface is formed on the contact part. The water outlet slider slides downward to make the first contact inclined surface and the second contact inclined surface fit, and forces the sliding part to slide downward. Through the above improvement, the sliding groove is arranged on the contact part. When the water outlet slider slides downward, the first contact inclined surface on the water outlet slider abuts against the second contact inclined surface on the contact part, and the first contact inclined surface and the second contact inclined surface are used in cooperation, thereby improving the sealing performance between the water outlet slider and the contact part and preventing water from flowing through the gap between the sliding groove and the sliding rod.

[0014] Preferably, the contact part includes a guide block fixed on the sliding part, a sliding block slidably arranged, and an elastic sealing ring arranged on the sliding block. The water outlet slider presses the elastic sealing ring to force the sliding block to slide downward, driving the sliding part to slide. Through the above improvement, as the water outlet slider presses the elastic sealing ring, the elastic sealing ring drives the sliding block to descend, thereby forcing the guide block to drive the entire sliding part to move to connect the pressure relief channel and the water storage cavity for pressure relief.

[0015] Preferably, an annular convex part is formed on the outer periphery of the elastic sealing ring, and the annular convex part fits with the inner wall of the sliding part. Through the above improvement, the elastic sealing ring is made of silicone material. As the water outlet slider presses the elastic sealing ring, the elastic sealing ring expands toward the circumferential side, ensuring the sealing performance between the contact part and the sliding part. Moreover, the annular convex part formed on the outer periphery of the elastic sealing ring further improves the sealing performance between the contact part and the sliding part.

[0016] Preferably, a sealing groove is formed on the outer periphery of the sliding part, and a pressure relief sealing ring is arranged in the sealing groove. The pressure relief sealing ring abuts against the inner wall of the valve body. Through the above improvement, the sealing performance between the entire pressure relief valve block group and the inner wall of the valve body is increased, preventing water from flowing through the gap between the pressure relief valve block group and the valve body.

[0017] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0018] By setting a pressure relief valve block group and a water outlet slider in the valve body to control the pressure, when the water outlet slider bears the first pressure, the water outlet slider slides and forms a water passing gap between the inner wall of the valve body to connect the water storage cavity and the water outlet channel. When the water outlet slider bears the second pressure, the water outlet slider abuts against the pressure relief valve block group and forces it to slide to connect the water storage cavity and the pressure relief channel, thereby relieving the pressure, and thus controlling the water pressure inside the valve body, that is, ensuring rapid water filling and avoiding damage to the equipment caused by excessive pressure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for easy understanding, rather than to define any directional or sequential limitations.

[0029] As Figure 1-7 shown, a fast water inlet and pressure relief valve includes a valve body 1, a pressure relief valve block group 2 and a water outlet slider 3 slidably arranged in the valve body 1. A water storage cavity 4 is formed in the valve body 1, a water injection channel 5 is formed at the end of the valve body 1, and a water outlet channel 6 and a pressure relief channel 7 are sequentially arranged on the side of the valve body 1 along the water flow direction.

[0030] Water enters the water storage cavity 4 along the water injection channel 5 and exerts a certain force on the water outlet slider 3, and the force at least includes a first pressure and a second pressure. When the water outlet slider 3 bears the first pressure, the water outlet slider 3 slides and a water passing gap 8 communicating the water storage cavity 4 and the water outlet channel 6 is formed between the water outlet slider 3 and the inner wall of the valve body 1. When the water outlet slider 3 bears the second pressure, the water outlet slider 3 abuts and forces the pressure relief valve block group 2 to slide to communicate the water storage cavity 4 and the pressure relief channel 7.

[0031] By arranging the pressure relief valve block group 2 and the water outlet slider 3 in the valve body 1 to control the pressure, when the water outlet slider 3 bears the first pressure, the water outlet slider 3 can only slide by itself. The water outlet slider 3 slides and a water passing gap 8 communicating the water storage cavity 4 and the water outlet channel 6 is formed between the water outlet slider 3 and the inner wall of the valve body 1, so as to quickly fill water under a specified water pressure. When the water outlet slider 3 bears the second pressure, the water outlet slider 3 will drive the pressure relief valve block group 2 to move together. The water outlet slider 3 slides downward and abuts against the pressure relief valve block group 2, pushing it downward to expose the pressure relief channel 7, so as to communicate the water storage cavity 4 and the pressure relief channel 7 to relieve pressure, controlling the water pressure inside the valve body 1, that is, ensuring quick water filling and avoiding damage to the equipment caused by excessive pressure.

[0032] Further explanation on the implementation manners of the first pressure and the second pressure in this embodiment. Herein, the water outlet slider 3 is floatingly arranged on the pressure relief valve block group 2, and in the initial state, the water outlet slider 3 closes the water outlet channel 6, and the pressure relief valve block group 2 closes the pressure relief channel 7. When the pressure borne by the water outlet slider 3 is greater than or equal to the first pressure and less than the second pressure, the water outlet slider 3 slides downward to connect the water storage cavity 4 and the water outlet channel 6. When the pressure borne by the water outlet slider 3 is greater than or equal to the second pressure, the water outlet slider 3 drives the pressure relief valve block group 2 to descend, and synchronously connects the water storage cavity 4 to the water outlet channel 6 and the pressure relief channel 7.

[0033] Among them, the first pressure is the normal water injection pressure. When the pressure borne by the water outlet slider 3 is greater than or equal to the first pressure and less than the second pressure, the water outlet slider 3 slides downward to connect the water storage cavity 4 and the water outlet channel 6 for rapid water filling. The second pressure is the overload pressure. When the pressure borne by the water outlet slider 3 is greater than or equal to the second pressure, the water outlet slider 3 drives the pressure relief valve block group 2 to descend, and synchronously connects the water storage cavity 4 to the water outlet channel 6 and the pressure relief channel 7 to relieve the pressure and return the internal pressure to the normal level.

[0034] As Figures 2 to 5 shown, further explanation on the implementation manner of the water outlet slider 3 in this embodiment. Herein, an arc-shaped inclined surface 101 is formed on the water outlet slider 3, and a water outlet inclined surface 102 is formed in the valve body 1. When the arc-shaped inclined surface 101 is in contact with the water outlet inclined surface 102, the valve body 1 is in a water-closed state. When the arc-shaped inclined surface 101 is away from the water outlet inclined surface 102 to form a water passing gap 8 to connect the water storage cavity 4 and the water outlet channel 6, the valve body 1 is in a water-passing state.

[0035] Among them, the valve body 1 includes a water-closed state, a water-passing state, and a pressure relief state. Since the water outlet slider 3 is integrally arranged in an arc shape and fits with the inner wall of the valve body 1, in the water-closed state, the arc-shaped inclined surface 101 is in contact with the water outlet inclined surface 102 and water cannot enter the water storage cavity 4. As the water outlet slider 3 is subjected to the pressure of the water in the water injection channel 5, the water outlet slider 3 will slide downward, causing the arc-shaped inclined surface 101 on the water outlet slider 3 to be away from the water outlet inclined surface 102 on the valve body 1 to form a water passing gap 8. At this time, the valve body 1 enters the water-passing state, so that water can be discharged through the water passing gap 8 to realize water filling for the coffee machine. In addition, as the water pressure increases, the water outlet slider 3 will continue to slide downward and drive the pressure relief valve block group 2 to slide, connecting the water storage cavity 4 to the pressure relief channel 7 to relieve the pressure and making the valve body 1 enter the pressure relief state.

[0036] Furthermore, a sliding rod 103 is formed at the bottom of the water outlet slider 3. A sliding groove 104 for the sliding rod 103 to be inserted is formed on the pressure relief valve block group 2, and a first elastic element 105 is sleeved on the sliding rod 103. One end of the first elastic element 105 abuts against the pressure relief valve block group 2, and the other end abuts against the water outlet slider 3, so that the water outlet slider 3 always has an upward movement tendency.

[0037] By using the cooperation of the sliding rod 103 and the sliding groove 104, the stability of the water outlet slider 3 during the sliding process is greatly improved. And when the pressure generated by water on the water outlet slider 3 is greater than the acting force of the first elastic element 105, the water outlet slider 3 will slide downward for water filling. And when the pressure of water on the water outlet slider 3 is less than the pressure of the second elastic element 203, the water outlet slider 3 will reset, so that the arc-shaped inclined surface 101 fits the water outlet inclined surface 102, making the valve body 1 in a water-closed state.

[0038] In addition, a limiting convex block 106 is formed on the inner wall of the valve body 1, and a limiting groove 107 for placing the limiting convex part is formed on the water outlet slider 3. By using the cooperation of the limiting convex part and the limiting groove 107, the water outlet slider 3 is prevented from rotating during the sliding process.

[0039] Preferably, the valve body 1 and the water outlet slider 3 form a nested water control convex part 308 at the top. When the water control convex parts 308 are in contact with each other, water cannot enter the water storage cavity 4 through the water injection channel 5. As the water outlet slider 3 slides downward, the water control convex parts 308 are separated, and a water passing channel is formed between the water control convex parts 308, allowing water to enter the water storage cavity 4.

[0040] As Figure 2 、 Figure 6 、 Figure 7 As shown, for a further explanation of the implementation manner of the pressure relief valve block group 2 in this embodiment, the pressure relief valve block group 2 includes a sliding part 201 slidably arranged in the valve body 1, a contact part 202 placed in the sliding part 201, and a second elastic element 203 arranged at the bottom of the sliding part 201. One end of the second elastic element 203 abuts against the valve body 1, and the other end abuts against the sliding part 201. The water outlet slider 3 presses downward on the contact part 202, causing the sliding part 201 to slide downward and exposing the pressure relief channel 7 to connect the water storage cavity 4 and the pressure relief channel 7.

[0041] When the pressure received by the water outlet slider 3 is the second pressure or exceeds the second pressure, the water outlet slider 3 first slides downward to connect the water storage cavity 4 and the water outlet channel 6, and continues to slide downward to abut against the contact part 202, so that the water outlet slider 3 drives the sliding part 201 to continue to slide downward, exposing the pressure relief channel 7 and connecting the water storage cavity 4 for pressure relief. When the pressure drops below the second pressure, the second elastic element 203 will drive the sliding part 201 to move upward to cut off the connection between the water storage cavity 4 and the pressure relief channel 7 to stop the pressure relief, ensuring the water filling speed.

[0042] Specifically, the contact part 202 includes a guide block 301 fixed on the sliding part 201, a sliding block 302 slidably arranged, and an elastic sealing ring 303 arranged on the sliding block 302. The water outlet slider 3 presses the elastic sealing ring 303 to force the sliding block 302 to slide downward to drive the sliding part 201 to slide.

[0043] During the pressure relief process, as the water outlet slider 3 presses against the elastic sealing ring 303, the elastic sealing ring 303 drives the sliding block 302 to descend, thereby forcing the guiding block 301 to drive the entire sliding part 201 to move, so as to connect the pressure relief channel 7 and the water storage cavity 4 for pressure relief.

[0044] Specifically, a first abutting inclined surface 204 is formed on the water outlet slider 3, a second abutting inclined surface 205 is formed on the abutting part 202, and the water outlet slider 3 slides downward so that the first abutting inclined surface 204 and the second abutting inclined surface 205 are in contact, and the sliding part 201 is forced to slide downward.

[0045] Furthermore, the sliding groove 104 is arranged on the abutting part 202. When the sliding rod 103 of the water outlet slider 3 slides downward, the first abutting inclined surface 204 on the water outlet slider 3 will abut against the second abutting inclined surface 205 on the abutting part 202. By using the cooperation of the first abutting inclined surface 204 and the second abutting inclined surface 205, the sealing performance between the water outlet slider 3 and the abutting part 202 is improved, and water is prevented from flowing through the gap between the sliding groove 104 and the sliding rod 103.

[0046] In addition, an annular convex part 304 is formed on the outer periphery of the elastic sealing ring 303, and the annular convex part 304 is in contact with the inner wall of the sliding part 201. The elastic sealing ring 303 is made of silica gel material. As the water outlet slider 3 presses against the elastic sealing ring 303, the elastic sealing ring 303 expands toward the circumferential side, ensuring the sealing performance between the abutting part 202 and the sliding part 201. Moreover, the annular convex part 304 is formed on the outer periphery of the elastic sealing ring 303, further improving the sealing performance between the abutting part 202 and the sliding part 201.

[0047] As Figure 2 shown, preferably, a blocking convex part 305 is formed in the valve body 1. The blocking convex part 305 can limit the further upward movement of the sliding part 201 under the action of the second elastic element 203, so that it slides within a limited stroke.

[0048] As Figure 6 、 Figure 7 shown, preferably, a sealing groove 306 is formed on the outer periphery of the sliding part 201, and a pressure relief sealing ring 307 is arranged in the sealing groove 306. The pressure relief sealing ring 307 abuts against the inner wall of the valve body 1, increasing the sealing performance between the entire pressure relief valve block group 2 and the inner wall of the valve body 1, and preventing water from flowing through the gap between the pressure relief valve block group 2 and the valve body 1.

[0049] As Figure 2 、 Figure 3 shown, in some other embodiments, water blocking sealing rings 309 are arranged on the outer periphery of the water injection channel 5 and in the water outlet channel 6 respectively, so as to improve the sealing performance during the water injection and water outlet processes.

[0050] Preferably, the valve body 1 includes an upper housing and a lower housing respectively, and a sealing ring is also provided between the joint parts.

[0051] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
