Description

Technical Field

[0001] The present disclosure relates to the technical field of coffee making equipment, and in particular to a pressure-boosting regulating valve and a moka pot. Background Art

[0002] As people's living standards improve, coffee has gradually become an important part of their daily lives. Among them, the moka pot, as a tool for extracting espresso base, has become popular in households due to its convenience in making coffee. In order to further improve the convenience of using the moka pot, some manufacturers have made further research and development.

[0003] For example, Chinese patent CN113287942A discloses a booster valve for a moka pot, wherein the booster valve body has at least one input end and at least one output end; a chamber is disposed in the booster valve body and is used to connect the input end and the output end, the chamber is divided into a first part and a second part which can be connected to each other, and the first part and the second part have at least one angle A, and the fluid can enter the chamber through the first part and flow out from the second part; an elastic member is disposed at the connection between the first part and the second part, and the elastic member has at least a first mode and a second mode; wherein, in the first mode, the elastic member partially closes the connection between the first part and the second part; in the second mode, the elastic member is squeezed by an external force and opens the connection between the first part and the second part.

[0004] However, the design of the above-mentioned booster valve for the moka pot has the following problems:

[0005] Although the above-mentioned booster valve for moka pot can partially seal the pressure in the moka pot at the connecting part through the elastic part, when the user adjusts the brewing pressure of the moka pot, it is still necessary to manually take out and put the elastic part from the chamber, thereby replacing the elastic parts of different thicknesses in the chamber. Not only is the operation cumbersome and repetitive, but also one above-mentioned booster valve for moka pot requires the use of multiple elastic parts, which has a higher cost of use. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a pressure regulating valve and a moka pot that can quickly adjust the pressure boost intensity of coffee.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] A boost regulating valve, comprising a valve core and a valve cap; a liquid infusion channel is provided in the valve core; the valve core is used to be arranged on a liquid guide column of a moka pot body, and a liquid inlet end of the liquid infusion channel is used to be connected to a liquid outlet of the liquid guide column; the valve cap is covered at a liquid outlet end of the liquid infusion channel and forms an overflow gap with the valve core;

[0009] The boost regulating valve also includes a pressure plugging spring and an elastic boost plug nozzle;

[0010] The elastic pressurized plug nozzle is arranged in the infusion channel, and is used to abut against the peripheral wall of the lead-out port of the liquid-conducting column; a pressure-regulating middle cavity is formed between the valve cap and the elastic pressurized plug nozzle; the liquid inlet of the elastic pressurized plug nozzle is used to be connected to the lead-out port of the liquid-conducting column, and the liquid outlet of the elastic pressurized plug nozzle is connected to the overflow gap through the pressure-regulating middle cavity; the pressure-blocking spring is arranged in the pressure-regulating middle cavity; the valve cap is screwed to the valve core, and the liquid outlet of the elastic pressurized plug nozzle is pressed and closed by the pressure-blocking spring.

[0011] In one of the embodiments, the diameter of the blocking spring gradually decreases from an end close to the valve cap to an end close to the liquid outlet of the elastic booster plug nozzle.

[0012] In one of the embodiments, a boost flow channel is provided in the elastic boost plug nozzle, and the liquid inlet of the elastic boost plug nozzle is connected to the liquid outlet of the elastic boost plug nozzle through the boost flow channel.

[0013] In one of the embodiments, the transverse cross-section of the boost flow channel gradually decreases from an end close to the liquid inlet of the elastic boost plug nozzle to an end close to the liquid outlet of the elastic boost plug nozzle.

[0014] In one embodiment, the pressurized flow channel includes a connected guide chamber and a contraction chamber, the guide chamber is close to and connected to the liquid inlet of the elastic pressurized plug nozzle, the guide chamber is close to and connected to the liquid outlet of the elastic pressurized plug nozzle, and the contraction chamber is used to gather coffee liquid.

[0015] In one of the embodiments, the cavity wall of the contraction cavity is inclined from both sides to the middle at a first predetermined angle and moves toward the liquid outlet of the elastic booster plug nozzle.

[0016] In one embodiment, the first predetermined angle is 12° to 16°.

[0017] In one of the embodiments, the valve core is provided with a flow gap on the cavity wall of the pressure regulating middle cavity, and the flow gap is connected to the overflow gap.

[0018] In one of the embodiments, the liquid outlet of the elastic booster plug nozzle is a straight-line opening.

[0019] A moka pot comprises a moka pot body and a boost regulating valve according to any one of the above-mentioned embodiments, wherein the valve core is arranged on a liquid guiding column of the moka pot body, the liquid inlet end of the infusion channel is connected to a lead-out port of the liquid guiding column, the elastic boost plug nozzle abuts against a peripheral wall of the lead-out port, and the liquid inlet of the elastic boost plug nozzle is connected to the lead-out port of the liquid guiding column.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1) Because the liquid inlet of the elastic booster plug is connected to the outlet of the liquid guiding column, the coffee liquid flowing out of the outlet of the liquid guiding column can enter through the liquid inlet of the elastic booster plug and flow toward the liquid outlet of the boosting channel. Since the valve cap presses the liquid outlet of the boosting channel through the plugging spring, the liquid outlet of the boosting channel is in a retracted state, thereby increasing the brewing pressure of the moka pot, that is, the coffee liquid needs to be gathered and pressurized to overcome the elastic force of the plugging spring to open the liquid outlet of the boosting channel. Because the liquid outlet of the elastic booster plug is connected to the overflow gap through the pressure regulating middle cavity, the gathered and pressurized coffee liquid can flow out through the overflow gap for easy drinking.

[0022] 2) Because the valve cap is screwed to the valve core, the pressure of the plugging spring on the outlet of the elastic booster plug can be adjusted by twisting the valve cap, and the contraction strength of the outlet of the elastic booster plug can be quickly changed, thereby changing the brewing pressure of the moka pot. Only when the coffee liquid reaches the corresponding boosting strength can it overcome the elastic force of the plugging spring and be discharged from the outlet of the elastic booster plug, so that the coffee liquid can finally achieve different boosting effects. Compared with the booster valve for moka pots in the prior art, the booster regulating valve can adjust the pressure of the moka pot by simply twisting the valve cap, which not only avoids repeatedly taking and putting the elastic member to simplify the operation, but also avoids the waste caused by multiple elastic members being used in one moka pot.

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0032] like Figures 1 to 3As shown, a boost regulating valve 100 of an embodiment includes a valve core 110, a valve cap 120, a pressure blocking spring 130 and an elastic boost plug nozzle 140; an infusion channel 1110 is provided in the valve core 110; the valve core 110 is used to be arranged on the liquid guide column 210 of the moka pot body 200, and the liquid inlet end of the infusion channel 1110 is used to be connected to the outlet of the liquid guide column 210; the valve cap 120 is covered on the liquid outlet end of the infusion channel 1110, and an overflow gap 1113 is formed between the valve core 110; the elastic boost plug nozzle 140 is arranged in the infusion channel 1110, and Used to abut against the surrounding wall of the guide outlet of the liquid guiding column 210; a pressure regulating middle cavity 1111 is formed between the valve bonnet 120 and the elastic pressure boosting plug nozzle 140; the liquid inlet 1410 of the elastic pressure boosting plug nozzle 140 is used to be connected to the guide outlet of the liquid guiding column 210, and the liquid outlet 1420 of the elastic pressure boosting plug nozzle 140 is connected to the overflow gap 1113 through the pressure regulating middle cavity 1111; the pressure blocking spring 130 is arranged in the pressure regulating middle cavity 1111; the valve bonnet 120 is screwed to the valve core 110, and the pressure blocking spring 130 presses and closes the liquid outlet 1420 of the elastic pressure boosting plug nozzle 140.

[0033] It can be understood that because the liquid inlet 1410 of the elastic booster plug nozzle 140 is connected to the outlet of the liquid guiding column 210, the coffee liquid flowing out from the outlet of the liquid guiding column 210 can enter through the liquid inlet 1410 of the elastic booster plug nozzle 140 and flow toward the liquid outlet 1420 of the boosting channel. Since the valve cap 120 presses the liquid outlet 1420 of the boosting channel through the blocking spring 130, the liquid outlet 1420 of the boosting channel is in a retracted state, thereby increasing the brewing pressure of the moka pot 10, that is, the coffee liquid needs to be gathered and pressurized to overcome the elastic force of the blocking spring 130 to open the liquid outlet 1420 of the boosting channel. Because the liquid outlet 1420 of the elastic booster plug nozzle 140 is connected to the overflow gap 1113 through the pressure regulating middle cavity 1111, the gathered and pressurized coffee liquid can flow out through the overflow gap 1113 for easy drinking.

[0034] It can be understood that because the valve cap 120 is screwed to the valve core 110, the pressure of the plugging spring 130 on the liquid outlet 1420 of the elastic boosting plug nozzle 140 can be adjusted by twisting the valve cap 120, and the contraction strength of the liquid outlet 1420 of the elastic boosting plug nozzle 140 can be quickly changed, thereby changing the brewing pressure of the moka pot 10. Only when the coffee liquid reaches the corresponding boosting strength can it overcome the elastic force of the plugging spring 130 and be discharged from the liquid outlet 1420 of the elastic boosting plug nozzle 140, and finally the coffee liquid can achieve different boosting effects. Compared with the boosting valve for the moka pot 10 of the prior art, the boosting regulating valve 100 can adjust the pressure of the moka pot 10 by simply twisting the valve cap 120, which not only avoids repeatedly taking and putting the elastic member to simplify the operation, but also avoids the waste caused by multiple elastic members being applied to one moka pot 10.

[0035] Combination Figure 3 As shown, in one embodiment, one end of the pressure plugging spring 130 is connected to the valve cap 120; the other end of the pressure plugging spring 130 is connected to the elastic booster plug nozzle 140 and corresponds to the liquid outlet 1420 to open or close the liquid outlet 1420. It can be understood that the pressure of the pressure plugging spring 130 on the liquid outlet 1420 can be adjusted by twisting the valve cap 120, thereby realizing the opening or closing of the liquid outlet 1420. Specifically, one end of the pressure plugging spring 130 abuts against the valve cap 120; the other end of the pressure plugging spring 130 abuts against the elastic booster plug nozzle 140.

[0036] Combination Figure 1 and Figure 3 As shown, in one embodiment, the diameter of the plugging spring 130 is gradually reduced from one end close to the valve cap 120 to one end close to the liquid outlet 1420 of the elastic boost plug nozzle 140. It can be understood that by gradually reducing the diameter of the plugging spring 130 from one end close to the valve cap 120 to one end close to the liquid outlet 1420 of the elastic boost plug nozzle 140, the plugging spring 130 and the valve cap 120 have a larger contact area, and the plugging spring 130 can be smoothly compressed when the valve cap 120 is twisted, and by reducing the contact area between the plugging spring 130 and the liquid outlet 1420 of the elastic boost plug nozzle 140, the deformation toughness of the plugging spring 130 is improved, and then the adjustable accuracy of the plugging spring 130 is improved, so that the moka pot 10 can adjust more types of brewing pressures, and the situation that the plugging spring 130 presses and seals the liquid outlet 1420 of the elastic boost plug nozzle 140 can be reduced. Specifically, the blocking spring 130 may be a conical spring, but this is not limited here and those skilled in the art may also replace it as needed.

[0037] Combination Figure 3 As shown, in one embodiment, a pressurized flow channel 1430 is provided in the elastic pressurized plug nozzle 140, and the liquid inlet 1410 of the elastic pressurized plug nozzle 140 is connected to the liquid outlet 1420 of the elastic pressurized plug nozzle 140 through the pressurized flow channel 1430. It can be understood that since the liquid inlet 1410 of the elastic pressurized plug nozzle 140 is connected to the liquid outlet 1420 of the elastic pressurized plug nozzle 140 through the pressurized flow channel 1430, the coffee liquid entering through the liquid inlet 1410 of the elastic pressurized plug nozzle 140 can be discharged from the liquid outlet 1420 of the elastic pressurized plug nozzle 140 through the pressurized flow channel 1430, and the coffee liquid is pressurized in the pressurized flow channel 1430. After pressurization, the fat content of the coffee liquid is reduced, which can greatly improve the taste of the coffee.

[0038] Combination Figure 3As shown, in one embodiment, the transverse cross section of the pressurized flow channel 1430 gradually decreases from one end close to the liquid inlet 1410 of the elastic pressurized plug nozzle 140 to one end close to the liquid outlet 1420 of the elastic pressurized plug nozzle 140. It can be understood that since the transverse cross section of the pressurized flow channel 1430 gradually decreases from one end close to the liquid inlet 1410 of the elastic pressurized plug nozzle 140 to one end close to the liquid outlet 1420 of the elastic pressurized plug nozzle 140, when the coffee liquid flows along the pressurized flow channel 1430 from the liquid inlet 1410 of the elastic pressurized plug nozzle 140 to the liquid outlet 1420 of the elastic pressurized plug nozzle 140, the coffee liquid will be compressed by the pressurized flow channel 1430 and pressurized.

[0039] Combination Figure 3 As shown, in one embodiment, the pressurized flow channel 1430 includes a flow guide chamber 1431 and a contraction chamber 1432 that are connected. The flow guide chamber 1431 is close to and connected to the liquid inlet 1410 of the elastic pressurized plug nozzle 140, and the contraction chamber 1432 is close to and connected to the liquid outlet 1420 of the elastic pressurized plug nozzle 140. The contraction chamber 1432 is used to gather coffee liquid. It can be understood that since the flow guide chamber 1431 is close to and connected to the liquid inlet 1410 of the elastic pressurized plug nozzle 140, the coffee liquid entering from the liquid inlet 1410 of the elastic pressurized plug nozzle 140 can smoothly enter the contraction chamber 1432 through the flow guide chamber 1431, and the coffee liquid is gathered and pressurized through the contraction chamber 1432. After pressurization, the fat content of the coffee liquid is reduced, which can greatly improve the taste of the coffee.

[0040] Combination Figure 3 As shown, in this embodiment, the cavity wall of the contraction cavity 1432 is inclined from both sides to the middle at a first predetermined angle c, and moves closer to the liquid outlet 1420 of the elastic pressurizing plug nozzle 140. It can be understood that since the cavity wall of the contraction cavity 1432 is inclined from both sides to the middle at the first predetermined angle, that is, the vertical cross-section of the contraction cavity 1432 is A-shaped, by making the cavity wall of the contraction cavity 1432 inclined and moving closer to the liquid outlet 1420 of the elastic pressurizing plug nozzle 140, the coffee liquid can be continuously and smoothly gathered together along the cavity wall of the contraction cavity 1432, so that the pressurization process of the coffee liquid is more orderly and coherent, and the use is safer.

[0041] Combination Figure 3 As shown, specifically, the first predetermined angle c is 12° to 16°. It can be understood that by setting the first predetermined angle c within the range of 12° to 16°, it can not only avoid the situation that the elastic pressurizing plug nozzle 140 is difficult to release pressure in time due to the first predetermined angle c being too large, and then the liquid splashing, but also avoid the situation that the first predetermined angle c is too small to pressurize the coffee liquid. Among them, the first predetermined angle c can be 12°, 14° or 16°, of course, it is not limited here, and those skilled in the art can also make other choices according to needs.

[0042] Combination Figure 3 As shown, in one embodiment, the valve core 110 is provided with a flow notch 1112 on the cavity wall of the pressure regulating middle cavity 1111, and the flow notch 1112 is connected to the overflow gap 1113. It can be understood that by providing the flow notch 1112 on the cavity wall of the pressure regulating middle cavity 1111, the pressure regulating middle cavity 1111 can be connected to the overflow gap 1113 through the flow notch 1112, so that the coffee liquid can be discharged from the overflow gap 1113 more smoothly through the flow notch 1112, thereby improving the flow rate of the coffee liquid.

[0043] Combination Figure 1 As shown, in one embodiment, the liquid outlet 1420 of the elastic booster plug 140 is a straight opening. It can be understood that by setting the liquid outlet 1420 of the elastic booster plug 140 as a straight opening, the straight opening structure can be better closed after being pressed by the pressure spring 130.

[0044] Combination Figure 1 and Figure 2 As shown, the present disclosure also provides a moka pot 10, including a moka pot body 200 and a boost regulating valve 100 of any of the above-mentioned embodiments, the valve core 110 is arranged on the liquid guiding column 210 of the moka pot body 200, the liquid inlet end of the infusion channel 1110 is connected to the outlet of the liquid guiding column 210, the elastic boost plug nozzle 140 abuts against the peripheral wall of the outlet, and the liquid inlet 1410 of the elastic boost plug nozzle 140 is connected to the outlet of the liquid guiding column 210. It can be understood that by applying the boost regulating valve 100 disclosed in the present invention in the moka pot 10, the pressure of the plugging spring 130 on the liquid outlet 1420 of the elastic boost plug nozzle 140 can be adjusted by twisting the valve cap 120, and then the contraction strength of the liquid outlet 1420 of the elastic boost plug nozzle 140 can be quickly changed, thereby changing the brewing pressure of the moka pot 10. Only when the coffee liquid reaches the corresponding boost strength can it overcome the elastic force of the plugging spring 130 and be discharged from the liquid outlet 1420 of the elastic boost plug nozzle 140, and finally the outflowing coffee liquid can achieve different boost effects.

[0045] Combination Figure 2 As shown, in one embodiment, the moka pot body 200 includes an upper pot, a powder bowl, a lower pot and a liquid guide column 210 which are connected in sequence from top to bottom; the liquid guide column 210 is vertically placed in the upper pot, the inlet of the liquid guide column 210 is connected to the powder bowl, the powder bowl extends a conduit into the lower pot, and the side wall of the lower pot is provided with a pressure relief valve 220. It can be understood that by providing the pressure relief valve 220 on the side wall of the lower pot, when the pressure of the lower pot is too high, the pressure can be automatically relieved through the pressure relief valve 220, so as to avoid the situation where the moka pot 10 continuously heats the lower pot and an overpressure occurs, which may cause a safety accident.

[0046] In one embodiment, for better understanding, the steps of using the moka pot 10 are as follows:

[0047] Pour water into the lower pot, and the water level should not exceed the pressure relief valve 220; put coffee powder into the powder bowl; turn on the fire to heat the bottom of the lower pot, and the water in the lower pot will generate steam. The pressure of the steam will push the water into the powder bowl to extract the coffee liquid, and the coffee liquid will be pushed to the boost regulating valve 100 by the steam. The coffee liquid completes the first pressurization through the contraction cavity 1432, and completes the second pressurization when rushing out of the liquid outlet 1420 of the elastic boost plug 140, which can not only avoid the situation that the coffee liquid pressure fluctuates too much during extraction and the serious splashing when the liquid is discharged, but also through two gradual pressurizations, the coffee taste effect is good.

[0048] Compared with the prior art, the present invention has at least the following advantages:

[0049] 1) Because the liquid inlet 1410 of the elastic booster plug 140 is connected to the outlet of the liquid guiding column 210, the coffee liquid flowing out of the outlet of the liquid guiding column 210 can enter through the liquid inlet 1410 of the elastic booster plug 140 and flow toward the liquid outlet 1420 of the boosting channel. Since the valve cap 120 presses the liquid outlet 1420 of the boosting channel through the blocking spring 130, the liquid outlet 1420 of the boosting channel is in a retracted state, thereby increasing the brewing pressure of the moka pot 10, that is, the coffee liquid needs to be gathered and pressurized to overcome the elastic force of the blocking spring 130 to open the liquid outlet 1420 of the boosting channel. Because the liquid outlet 1420 of the elastic booster plug 140 is connected to the overflow gap 1113 through the pressure regulating middle cavity 1111, the gathered and pressurized coffee liquid can flow out through the overflow gap 1113 for easy drinking.

[0050] 2) Because the valve cap 120 is screwed to the valve core 110, the pressure of the plugging spring 130 on the liquid outlet 1420 of the elastic boosting plug nozzle 140 can be adjusted by twisting the valve cap 120, and the contraction strength of the liquid outlet 1420 of the elastic boosting plug nozzle 140 can be quickly changed, thereby changing the brewing pressure of the moka pot 10. Only when the coffee liquid reaches the corresponding boosting strength can it overcome the elastic force of the plugging spring 130 and be discharged from the liquid outlet 1420 of the elastic boosting plug nozzle 140, and finally the coffee liquid can achieve different boosting effects. Compared with the boosting valve for the moka pot 10 of the prior art, the boosting regulating valve 100 can adjust the pressure of the moka pot 10 by simply twisting the valve cap 120, which not only avoids repeatedly taking and putting the elastic member to simplify the operation, but also avoids the waste caused by applying multiple elastic members to one moka pot 10.

[0051] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
