Abstract
Description
Technical Field
[0001] This utility model specifically relates to an adaptive sealing valve and a water purifier and coffee maker incorporating the same. Background Technology
[0002] Water dispensers and coffee machines have water collection trays to temporarily hold spilled water or wastewater from the coffee machine's self-cleaning process. Currently, most wastewater in these trays needs to be manually emptied or drained using a pump. For water purifier-coffee combos, both the water purifier and the coffee machine's self-cleaning process generate wastewater that needs to be drained. To avoid reusing the pump, a Venturi jet drainage device can be used to drain the wastewater from the collection tray simultaneously with the water purifier's wastewater discharge.
[0003] In existing technology, a Venturi tube jet inlet is typically connected to the wastewater pipe, and a bypass pipe of the Venturi tube is connected to the coffee machine's wastewater collection box. When wastewater from the water purifier passes through the Venturi tube, a negative pressure is created, diverting the wastewater from the coffee machine's collection box and emptying it. However, after the wastewater is drained, the water purifier continues operating. Since the collection box contains only air, the bypass pipe of the Venturi tube draws air into the Venturi tube. This air mixes with the jet wastewater at the throat of the Venturi tube, generating significant noise and resulting in a poor user experience. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defect in the prior art where air is injected into the Venturi tube after the sewage in the water receiving box is emptied, resulting in a large noise, and to provide an adaptive sealing valve and a water purifier and coffee machine containing the same.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] An adaptive sealing valve is used to seal a bypass pipe of a venturi tube, the bypass pipe being connected to the drain outlet of a water receiving box, the adaptive sealing valve being disposed at the drain outlet, and the adaptive sealing valve further comprising:
[0007] A buoy, the interior of which is hollow;
[0008] The guide portion has a first end connected to the bottom of the water receiving box, and a second end extending away from the bottom of the water receiving box along the depth direction of the water receiving box. Multiple guide portions are provided and multiple guide portions are arranged around the outer periphery of the drain outlet. The float is located in the floating space formed by the multiple guide portions and is arranged corresponding to the drain outlet.
[0009] A limiting part is provided at the second end of the guide part.
[0010] In this solution, a float is used to seal the drain outlet after wastewater in the water collection box is emptied through the bypass pipe. This prevents air from the water collection box from being introduced into the bypass pipe, thus reducing noise and improving the user experience. Furthermore, guide and limiting parts guide and limit the float to prevent it from deviating from the floating space and failing to seal the drain outlet, or from detaching from the guide part and falling out of the floating space, thus preventing the drain outlet from being sealed.
[0011] Preferably, the outer edge of the float is provided with a guide plate, and the guide plate has multiple through holes, with the guide portion passing through the through holes.
[0012] In this solution, the above-mentioned settings are used to enhance the guiding effect of the guide unit on the float.
[0013] Preferably, the guide portion and the limiting portion are integrally formed or detachably connected.
[0014] In this solution, the above settings are used to effectively limit the movement of the float.
[0015] Preferably, the guide part is a cylindrical rod, the limiting part is an annulus, and the diameter of the annulus hole of the limiting part is smaller than the diameter of the float.
[0016] In this scheme, the above-mentioned settings are used to guide the floating direction of the float by using cylindrical rods, and to prevent the float from leaving the floating space by using an annular hole smaller than the float.
[0017] Preferably, the adaptive sealing valve further includes a buoyancy section, one end of which is connected to the guide plate and the other end of which is connected to the limiting section. The buoyancy section is used to provide buoyancy for the float to move away from the drain outlet.
[0018] In this solution, the above settings are used to prevent the float from closing the drain outlet when the water level in the water receiving box is low and the buoyancy generated is small. This prevents the float from closing the drain outlet when the sewage in the water receiving box has not been emptied, thereby improving the sealing accuracy of the adaptive sealing valve.
[0019] Preferably, the buoyancy provided by the buoyancy section is less than the negative pressure of the bypass tube of the venturi tube.
[0020] In this solution, the above settings are used to prevent the float from failing to seal the drain outlet after the sewage in the water collection box has been emptied.
[0021] Preferably, multiple buoyancy components are provided, and each buoyancy component is located between two adjacent guide components.
[0022] In this solution, the above settings provide uniform buoyancy to the float, avoiding situations where the buoy has high buoyancy in some areas and low buoyancy in others, and where the low buoyancy areas close the drain outlet.
[0023] Preferably, the guide portion is a helical rod.
[0024] In this solution, the above-mentioned setup utilizes a spiral rod to slow down the speed at which the float closes the drain outlet, thereby indirectly increasing the buoyancy of the float. This prevents the float from closing the drain outlet when the water level in the water collection box is low and the buoyancy is small, thus preventing the float from closing the drain outlet before the sewage in the water collection box is emptied.
[0025] Preferably, the pitch of the portion of the guide near the drain outlet is smaller than the pitch of the portion of the guide near the limiting portion.
[0026] In this solution, the above settings are used to further reduce the movement speed of the float when it approaches the drain outlet, that is, to increase the buoyancy of the float in the area near the drain outlet, so as to improve the sealing accuracy.
[0027] A water purifier and coffee maker, the water purifier and coffee maker including the adaptive sealing valve as described above.
[0028] In this solution, the integrated water purifier and coffee maker includes the aforementioned adaptive sealing valve. While wastewater is ejected through the venturi tube, wastewater in the collection box is simultaneously ejected through a bypass pipe, achieving rapid wastewater emptying without the need for additional drainage structures such as a water pump. This results in lower costs and a correspondingly improved user experience. Furthermore, the adaptive sealing valve seals the drain outlet after wastewater is drained, preventing air from being ejected into the venturi tube and generating noise, further enhancing the user experience.
[0029] The positive and progressive effects of this utility model are as follows: By incorporating a float, after the wastewater in the water receiving box is emptied through the bypass pipe, the float seals the drain outlet, preventing air from the water receiving box from being introduced into the bypass pipe and generating noise, thus achieving noise reduction and improving the user experience. Furthermore, the guide and limiting parts guide and limit the float, preventing it from deviating from the floating space and failing to seal the drain outlet, or from detaching from the guide part and deviating from the floating space, thus failing to seal the drain outlet.

[0047] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0048] This embodiment provides an adaptive sealing valve, the specific structure of which is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the adaptive sealing valve is used to seal the bypass pipe 11 of the venturi tube 1. The bypass pipe 11 is connected to the drain port 21 of the water receiving box 2. The adaptive sealing valve is located at the drain port 21. The adaptive sealing valve also includes:
[0049] Float 3, the interior of float 3 is hollow;
[0050] The guide part 4 has a first end connected to the bottom of the water receiving box 2, and a second end extending away from the bottom of the water receiving box 2 along the depth direction A of the water receiving box 2. Multiple guide parts 4 are provided and multiple guide parts 4 are arranged around the outer periphery of the drain outlet 21. The float position 3 is located in the floating space formed by the multiple guide parts 4 and is set corresponding to the drain outlet 21.
[0051] Limiting part 5 is provided at the second end of guide part 4.
[0052] Specifically, the drain outlet 21 is a circular hole, and the bypass pipe 11 connects to the water receiving box 2 through the drain outlet 21. Utilizing the ejector effect of the Venturi tube 1, the sewage in the water receiving box 2 is simultaneously ejected and emptied while the wastewater is being ejected, achieving automatic sewage emptying without the need for an additional water pump structure. This is existing technology and will not be elaborated upon here. In this embodiment, the adaptive valve body is located inside the water receiving box 2 at the drain outlet 21. The adaptive valve body includes a hollow float 3, which floats within the water receiving box 2 and closes the drain outlet 21 according to the sewage level. Specifically, when the sewage is emptied, the float 3, lacking buoyancy, is located at the bottom of the water receiving box 2, and the drain outlet 21 is closed by the float 3 to prevent air from being ejected into the Venturi tube 1, thus preventing noise and improving the user experience.
[0053] Furthermore, to ensure that the float 3 can effectively seal the drain outlet 21 when the sewage is drained, this embodiment also provides a guide part 4 and a limiting part 5. The guide part 4 is erected at the bottom of the water receiving box 2 and extends from the bottom of the water receiving box 2 along the depth direction A of the water receiving box 2 away from the bottom of the water receiving box 2. Multiple guide parts 4 are provided, and multiple guide parts 4 are arranged around the outer periphery of the drain outlet 21. This embodiment uses four guide parts 4 as an example for explanation, but the number is not limited. In other embodiments, the number of guide parts 4 can also be three or five, etc. The four guide parts 4 are evenly distributed on the outer periphery of the drain outlet 21. The four guide parts 4 are arranged at intervals and form a floating space around the center of gravity of the four guide parts 4. The floating space corresponds to the drain outlet 21. The float 3 is located in the floating space and is guided by the guide parts 4 so that when the water level of the sewage changes, the float 3 is always in the floating space and floats up and down corresponding to the drain outlet 21.
[0054] In addition, this embodiment also includes a limiting part 5, which is located at the second end of the guide part 4, that is, at the end of the guide part 4 away from the bottom of the water receiving box 2. By providing the limiting part 5, the float 3 is prevented from leaving the floating space formed by the multiple guide parts 4 when the water level of the sewage is higher than the height of the second end of the guide part 4. The limiting part 5 can keep the float 3 within the floating space at all times, and when the water level of the sewage drops again, the float 3 can still be guided by the guide part 4 and close the drain outlet 21 in time.
[0055] In this embodiment, a guide plate 31 is provided on the outer edge of the float 3, and a plurality of through holes 32 are provided on the guide plate 31, with the guide part 4 passing through the through holes 32.
[0056] Specifically, the guide plate 31 is a plate that protrudes outward from the outer edge of the float 3. From the appearance, the guide plate 31 has a circular structure. The guide plate 31 and the float 3 are integrally formed. The guide plate 31 has multiple through holes 32 corresponding to the guide part 4. The float 3 is slidably connected to the guide part 4 through the through holes 32. When the float 3 floats up and down according to the water level of the sewage, the through holes 32 and the guide part 4 cooperate to enhance the guiding effect of the guide part 4 on the float 3.
[0057] Furthermore, in this embodiment, the guide portion 4 and the limiting portion 5 are integrally formed or detachably connected.
[0058] Specifically, the first end of the guide part 4 can be connected to the bottom of the water receiving box 2 through a snap-fit structure in the prior art, and the second end of the guide part 4 is integrally formed with the limiting part 5. Thus, during the floating process of the float 3, the limiting part 5 limits the float 3 and prevents it from leaving the floating space.
[0059] Of course, in other embodiments, the guide part 4 and the limiting part 5 can also be detachably connected. For example, the first end of the guide part 4 can be connected to the bottom of the water receiving box 2 through a snap-fit structure in the prior art, and the second end of the guide part 4 can be connected to the limiting part 5 through a snap-fit structure in the prior art. The purpose is also to effectively limit the float 3.
[0060] In this embodiment, the guide part 4 is a cylindrical rod, and the limiting part 5 is a ring. The diameter of the ring hole in the limiting part 5 is smaller than the diameter of the float 3.
[0061] Specifically, the guide part 4 is a cylindrical rod with a straight axis, which guides the floating direction of the float 3. The limiting part 5 is a ring structure. Compared to the disc structure, the ring structure has a ring hole, which prevents the float 3 from leaving the floating space by making the ring hole smaller than the float 3. Furthermore, the ring hole allows water to flow through, so that the float 3 can float up and down in a timely manner according to water level changes. This avoids the situation where the surface tension of the water pulls the float 3 when the disc structure is flush with the water level, preventing the float 3 from floating up and down in a timely manner according to water level changes.
[0062] like Figure 4 As shown, in this embodiment, the adaptive sealing valve also includes a buoyancy part 6. One end of the buoyancy part 6 is connected to the guide plate 31, and the other end of the buoyancy part 6 is connected to the limiting part 5. The buoyancy part 6 is used to provide buoyancy for the float 3 to move away from the drain outlet 21.
[0063] Specifically, the buoyancy part 6 can be a spring or a damping structure, which are existing technologies and will not be elaborated further here. This embodiment uses a spring as an example for the buoyancy part 6. One end of the spring is connected to the limiting part 5, and the other end is connected to the side of the guide plate 31 away from the bottom of the water receiving box 2. When the water level in the water receiving box 2 is low and the buoyancy is small, to prevent insufficient buoyancy of the float 3 and a large negative pressure generated by the venturi tube 1, which could cause the float 3 to be sucked into the water and close the drain outlet 21 even when there is water in the water receiving box 2, the buoyancy part 6 prevents the float 3 from closing the drain outlet 21, allowing the sewage with a low water level to be completely drained. This avoids the float 3 closing the drain outlet 21 when the sewage in the water receiving box 2 is not emptied, thus improving the sealing accuracy of the adaptive sealing valve.
[0064] In this embodiment, the elastic force generated by the spring, i.e., the buoyancy, is Fbuoyancy, and the suction force of the negative pressure generated by the Venturi tube 1 is Fsuction. Fbuoyancy + 4kx = Fsuction, where k is the spring constant and x is the maximum length of the spring after stretching. It can be understood that when the sewage is drained, the spring is stretched to its maximum length, and the initial length of the spring is l. l + x = L, where L is the extension length of the guide part 4 along the depth direction A of the water receiving box 2.
[0065] In this embodiment, the buoyancy provided by the buoyancy part 6 is less than the negative pressure of the bypass pipe 11 of the venturi tube 1, so as to avoid the buoyancy provided by the buoyancy part 6 being too large, and the float ball 3 being unable to seal the drain outlet 21 after the sewage in the water receiving box 2 is emptied.
[0066] In this embodiment, multiple buoyancy parts 6 are provided, and each buoyancy part 6 is located between two adjacent guide parts 4.
[0067] Specifically, there are four guide sections 4 and four buoyancy sections 6. Each buoyancy section 6 is located between two adjacent guide sections 4. From the appearance, the four guide sections 4 and four buoyancy sections 6 passing through the guide plate 31 are staggered. Compared with one buoyancy section 6, the four buoyancy sections 6 can provide a uniform buoyancy for the float 3, avoiding the situation where the buoyancy of the float 3 is large in some areas and small in the remaining areas. In addition, when the water level in the water receiving box 2 is low, the remaining areas with small buoyancy will block the drain outlet 21 due to the small buoyancy provided by the sewage.
[0068] like Figure 5 As shown, in another embodiment, the guide part 4 is a spiral rod.
[0069] Specifically, the guide part 4 is a spiral structure as in the prior art. The spiral structure has a uniform outer diameter. Compared to a cylindrical rod with a straight axis, the spiral guide part 4 can increase the movement path of the float 3 when it floats up and down with the guide plate 31, thereby slowing down the speed at which the float 3 closes the drain outlet 21. This effectively increases the buoyancy of the float 3, preventing it from closing the drain outlet 21 before the wastewater in the water receiving box 2 is emptied when the water level in the water receiving box 2 is low and the buoyancy is small. It is understandable that when the guide part 4 is a spiral structure, there is no need to set up the buoyancy part 6, thus reducing the manufacturing cost of the adaptive sealing valve.
[0070] It should be noted that the spiral direction of each guide part 4 is the same to avoid the float 3 being locked when the spiral direction is opposite.
[0071] Furthermore, the pitch of the portion of the guide 4 near the drain outlet 21 is smaller than the pitch of the portion of the guide 4 near the limiting portion 5.
[0072] Specifically, the guide part 4 has a spiral structure and the pitch decreases sequentially from the part near the limiting part 5 toward the part near the drain outlet 21. This makes the movement speed of the float 3 in closing the drain outlet 21 further slowed down when the float 3 floats toward the drain outlet 21, that is, when the water level in the water receiving box 2 is low and the buoyancy is insufficient. In other words, the buoyancy of the float 3 is increased in the area near the drain outlet 21 to improve the sealing accuracy.
[0073] This embodiment also provides a water purifier and coffee maker, which includes the aforementioned adaptive sealing valve. While wastewater is ejected through the Venturi tube 1, wastewater in the water collection box 2 is ejected through the bypass pipe 11, achieving rapid wastewater drainage without the need for additional drainage structures, such as a water pump. This results in lower costs and a correspondingly improved user experience. Furthermore, the adaptive sealing valve seals the drain outlet after wastewater drainage to prevent air from being ejected into the Venturi tube 1 and generating noise, further enhancing the user experience.
[0074] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
