Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a water outlet mechanism for a liquid heater. Background Technology

[0002] Patent document CN206324661U discloses "a novel coffee pot drainage structure," which specifically includes "a novel coffee pot drainage structure comprising a pot body and a drain outlet located at the bottom of the pot body. The bottom of the pot body also includes a sealing valve, a lever, and a solenoid valve. The sealing valve is located below the drain outlet. The middle of the lever is connected to a shaft at the bottom of the pot body. One end of the lever is connected to the sealing valve, and the other end is connected to the solenoid valve. The solenoid valve drives the lever to swing, causing the sealing valve to move up and down to close or open the drain outlet. By utilizing the solenoid valve to drive the lever to swing, the sealing valve on the lever separates from or contacts the drain outlet, achieving drainage and sealing of the coffee machine. This keeps the solenoid valve away from the high-temperature boiling water at the drain outlet, helping to protect the operating temperature and service life of the solenoid valve."

[0003] However, the installation of solenoid valves increases the overall material cost of the product, and when the solenoid valves malfunction, they can also affect the normal water output function of the equipment.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a water outlet mechanism for a liquid heater. The user can turn the handle to make the water outlet open. The structure is simple, which helps to reduce material costs. Moreover, the probability of failure is relatively small, and the water outlet function of the equipment is more stable.

[0006] The purpose of this utility model is achieved as follows: A water outlet mechanism for a liquid heater includes a container body, a water outlet section at the water outlet end of the container body, a trigger element and a switch valve element for opening or closing the water outlet section, the trigger element being connected to a transmission element, and the transmission element being connected to a handle section.

[0007] The handle rotates forward, which drives the transmission component to rotate and form the first operating state, causing the trigger to push the switch valve upward and open the water outlet.

[0008] The handle rotates in the opposite direction, which drives the transmission component to rotate to form a second operating state, causing the trigger to move downward and the switch valve to reset, thus cutting off the water outlet.

[0009] As a specific embodiment, the lower side of the container body is provided with a base, the transmission component is provided with a first retaining component, and the base is provided with a second retaining component corresponding to the first retaining component. When the triggering component pushes the switch valve component upward and causes the water outlet to be open, the first retaining component and the second retaining component are connected and cooperate to keep the transmission component in the first use state.

[0010] As a specific solution, the first retainer and the second retainer are connected and fixed by magnetic attraction.

[0011] As a specific embodiment, the switching valve includes a contact part and a sealing part. The water outlet part is provided with a water outlet hole. The sealing part is located above the water outlet hole. The contact part extends downward through the water outlet hole. A gap is formed between the contact part and the water outlet hole to allow water to flow through. When the trigger moves upward and pushes up the contact part, the sealing part separates from the water outlet hole, making the water outlet hole open.

[0012] As a specific embodiment, a reset spring is provided between the contact part and the lower periphery of the water outlet. When the trigger moves upward, the reset spring deforms and stores force. In the first use state, the handle part can drive the transmission part to rotate and switch to the second use state by rotating in the opposite direction. When the trigger part switches from the first use state to the second use state, the trigger part separates from the contact part, and the reset spring resets and drives the contact part to move downward so that the sealing part abuts against the water outlet and seals.

[0013] As a specific embodiment, the transmission component is movably connected to the water outlet, the water outlet is provided with a limiting part, and the handle is connected with a reset torsion spring. The reset torsion spring can drive the handle to rotate in the opposite direction and switch from the first use state to the second use state. In the second use state, the transmission component abuts against the limiting part.

[0014] As a specific embodiment, the transmission component is provided with an eccentric part, which is radially offset from the rotation axis of the transmission component by bending. One end of the trigger component is connected and engaged with the eccentric part, and the other end of the trigger component extends toward the switch valve component. When the handle part drives the transmission component to rotate by forward rotation, the eccentric part swings upward and pushes the trigger component to move upward.

[0015] As a specific embodiment, the water outlet section includes an upper water outlet cover, a connecting pipe, and a lower water outlet cover arranged sequentially from top to bottom. The upper end of the connecting pipe is sleeved on the outside of the upper water outlet cover, and the lower end of the connecting pipe is tightly fitted with the water inlet end of the lower water outlet cover. The transmission component is movably connected to the lower water outlet cover and the connecting pipe, and a sealing component is provided between the transmission component and the lower water outlet cover and the connecting pipe.

[0016] As a specific solution, the inner side of the connecting pipe is provided with a water-blocking rib. When the transmission component is in the first use state, the eccentric part stands vertically on the lower side of the water-blocking rib.

[0017] As a specific embodiment, the triggering element includes a connecting part and a triggering part. The triggering part is elongated in shape, and a limiting hole corresponding to the triggering part is provided on the water-blocking rib. The triggering part extends upward through the limiting hole, and the eccentric part can drive the connecting part to move up and down, and the connecting part can swing relative to the eccentric part, so that the triggering part moves up and down within the range of the limiting hole.

[0018] The beneficial effects of this utility model are: Users can turn the handle to open the water outlet. The simple structure helps reduce material costs and reduces the chance of failure, making the water output function of the equipment more stable. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] See Figures 1-14 The water outlet mechanism for this liquid heater includes a container body 1. The water outlet end of the container body 1 is provided with a water outlet section. The water outlet section is provided with a trigger 3 and a switch valve 2 for opening or closing the water outlet section. The trigger 3 is connected to a transmission component 4, and the transmission component 4 is connected to a handle section 7.

[0035] The handle 7 can drive the transmission component 4 to rotate by rotating in the forward direction to form the first use state, so that the trigger 3 pushes the switch valve 2 upward and causes the water outlet to be opened.

[0036] like Figure 1 , Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 13 As shown, the handle 7 can drive the transmission component 4 to rotate in the forward direction to form the first use state, so that the trigger component 3 pushes the switch valve component 2 upward and makes the water outlet open. The user can achieve the effect of opening the water outlet by rotating the handle 7. The structure is simple, which helps to reduce material costs, and the probability of failure is relatively small, making the water outlet function of the equipment more stable.

[0037] The handle 7 can drive the transmission component 4 to rotate by rotating in the opposite direction to form a second use state, causing the trigger 3 to move downward and the switch valve 2 to reset and shut off the water outlet.

[0038] The water outlet mechanism of this liquid heater can be used in water-using equipment such as electric kettles, water dispensers, water purifiers, and coffee machines.

[0039] Preferably, the water outlet is located at the bottom of the container body 1, and a filter screen is provided at the bottom of the container body 1 corresponding to the water inlet end of the water outlet.

[0040] Furthermore, a base 5 is provided on the lower side of the container body 1, a first retaining member 61 is provided on the transmission member 4, and a second retaining member 62 corresponding to the first retaining member 61 is provided on the base 5. When the trigger member 3 pushes the switch valve member 2 upward and causes the water outlet to be open, the first retaining member 61 and the second retaining member 62 are connected and cooperate to keep the transmission member 4 in the first use state. When the user rotates the handle part 7 to open the water outlet, there is no need to keep holding the handle part 7. The cooperation of the first retaining member 61 and the second retaining member 62 can keep the water outlet open, simplifying the user's operation difficulty.

[0041] Furthermore, the first retainer 61 and the second retainer 62 are connected and fixed by magnetic attraction. The first retainer 61 and the second retainer 62 can be a combination of magnet and metal iron. Compared with the shape matching method (such as snap-fit ​​matching), the shape and connection structure of the first retainer 61 and the second retainer 62 are simpler, which improves the stability of the connection between the two.

[0042] Furthermore, the switch valve 2 includes a contact part 21 and a sealing part 22. The water outlet part is provided with a water outlet hole 111. The sealing part 22 is located above the water outlet hole 111. The contact part 21 extends downward through the water outlet hole 111. A gap is formed between the contact part 21 and the water outlet hole 111 to allow water to flow through. When the trigger 3 moves upward and pushes up the contact part 21, the sealing part 22 separates from the water outlet hole 111, making the water outlet hole 111 open.

[0043] Furthermore, a return spring 211 is provided between the contact part 21 and the lower periphery of the water outlet 111.

[0044] like Figure 2 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 As shown, when the trigger 3 moves upward, the return spring 211 deforms and stores force; the handle 7 can drive the transmission 4 to rotate and switch to the second use state by rotating in the opposite direction in the first use state. When the trigger 3 switches from the first use state to the second use state, the trigger 3 separates from the contact part 21, and the return spring 211 resets and drives the contact part 21 to move downward so that the sealing part 22 abuts against the water outlet 111 and seals it. The return spring 211 can automatically reset the trigger 3 and stop the water outlet from supplying water to the outside, further simplifying the user's operation.

[0045] Furthermore, the transmission component 4 is movably connected to the water outlet, and the water outlet is provided with a limiting part 511. The handle part 7 is connected to a reset torsion spring 71. The reset torsion spring 71 can drive the handle part 7 to rotate in the opposite direction and switch from the first use state to the second use state. In the second use state, the transmission component 4 abuts against the limiting part 511. The reset torsion spring 71 can assist the user in controlling the reverse rotation of the handle part 7. When the user does not need the water outlet to supply water, he only needs to rotate the handle part 7 in the opposite direction to overcome the connecting force between the first retaining member 61 and the second retaining member 62. Then the handle part 7 can automatically reset under the action of the reset torsion spring 71. Under the action of the limiting part 511, the handle part 7 will stop rotating in the opposite direction after driving the transmission component 4 to rotate to a certain angle, so as to avoid the handle part 7 from rotating too much and damaging the reset torsion spring 71.

[0046] Furthermore, the transmission component 4 is provided with an eccentric part 41, which is radially offset from the rotation axis of the transmission component 4 by bending. One end of the trigger 3 is connected and cooperates with the eccentric part 41, and the other end of the trigger 3 extends toward the switch valve component 2. When the handle part 7 drives the transmission component 4 to rotate by forward rotation, the eccentric part 41 swings upward and pushes the trigger 3 to move upward. When the eccentric part 41 swings upward, it can further increase the upward movement of the trigger 3 during the forward rotation of the handle part 7, so that the trigger 3 can better act on the switch valve component 2.

[0047] Furthermore, the water outlet section includes an upper water outlet cover 11, a connecting pipe 8, and a lower water outlet cover 51, which are arranged sequentially from top to bottom. The upper end of the connecting pipe 8 is sleeved on the outside of the upper water outlet cover 11, and the lower end of the connecting pipe 8 is tightly fitted with the water inlet end of the lower water outlet cover 51. The connecting pipe 8 can reduce the chance of liquid leaking outward at the position between the upper water outlet cover 11 and the lower water outlet cover 51.

[0048] The transmission component 4 is movably connected to the water outlet cover 51 and the connecting pipe 8 respectively. A sealing component 42 is provided between the transmission component 4, the water outlet cover 51 and the connecting pipe 8. The sealing component 42 can prevent liquid from leaking outward along the transmission component 4.

[0049] Furthermore, the inner side of the connecting pipe 8 is provided with a water-blocking rib 81. When the transmission component 4 is in the first use state, the eccentric part 41 stands vertically on the lower side of the water-blocking rib 81. The water-blocking rib 81 can block the eccentric part 41 in the first use state, reducing the chance of liquid directly contacting the eccentric part 41, making it less likely for liquid to leak outward along the eccentric part 41 and the transmission component 4.

[0050] Furthermore, the trigger 3 includes a connecting part 31 and a trigger part 32. The trigger part 32 is elongated. The water-blocking rib part 81 is provided with a limiting hole 811 corresponding to the trigger part 32. The trigger part 32 extends upward through the limiting hole 811. The eccentric part 41 can drive the connecting part 31 to move up and down, and the connecting part 31 can swing relative to the eccentric part 41, so that the trigger part 32 moves up and down within the range of the limiting hole 811. By setting the limiting hole 811, the water-blocking rib part 81 can also limit the trigger part 32. When the eccentric part 41 swings up and down, with the cooperation of the limiting hole 811, the trigger part 32 can move up and down, improving the stability of the trigger part 32 during the lifting and lowering process and preventing the trigger part 32 from accidentally shifting and failing to function properly on the switch valve 2.

[0051] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
