Self-locking structure of filter basket liquid outlet hole

Abstract

This application provides a self-locking structure for the liquid outlet of a filter basket, including a filter basket body mounted on a machine body; it also includes a movable component and a valve core. The lower end of the filter basket body has a liquid outlet, and a baffle is provided on the machine body. The lower end of the filter basket body has a valve core, and one end of the valve core has a movable component. The movable component cooperates with the baffle to drive the valve core to move up and down. When the filter basket body is closed, the filter basket body moves upward, the baffle causes one end of the movable component to move, and the other end of the movable component moves in the opposite direction to drive the valve core to move, thereby opening the liquid outlet. During the closing process of the filter basket, the movement of the filter basket body causes the movable component to contact the baffle. The baffle, during the movement of the filter basket body, causes the movable component to move. Due to the lever principle, the valve core moves, opening the liquid outlet, thereby opening the filter basket and allowing the internal liquid to flow out of the filter basket. This allows residual liquid in the filter basket to flow out and into the water collection tray on the machine body, preventing pollution of the indoor environment.

Description

Technical Field

[0001] This application relates to the technical field of coffee machines, specifically to a self-locking structure for the liquid outlet of a filter basket. Background Technology

[0002] A coffee machine is a common household appliance that can automatically brew coffee powder.

[0003] When the coffee filter basket is opened to remove grounds or coffee grounds are added manually, there will still be liquid or coffee grounds inside the filter basket. The dispensing mechanism is not equipped with a corresponding locking structure when the door is opened, which allows the coffee liquid to be collected normally during brewing. When the filter basket is opened, the dispensing mechanism is closed, causing the residual coffee liquid in the filter basket to drip onto the countertop or floor and pollute the indoor environment. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of this, this application provides a self-locking structure for the outlet hole of the filter basket. When the moving component contacts the baffle, it drives the valve core to move. The valve core opens the outlet hole, allowing the residual liquid in the filter basket to flow out and into the water receiving tray of the machine body without polluting the indoor environment.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, this utility model provides a self-locking structure for the liquid outlet of a filter basket, including a filter basket body mounted on a machine body; it also includes a movable component and a valve core, with a liquid outlet at the lower end of the filter basket body, a baffle rib on the machine body, and the valve core at the lower end of the filter basket body, with the movable component at one end of the valve core, the movable component cooperating with the baffle rib to drive the valve core to move up and down;

[0008] When the filter basket body is closed, the filter basket body moves upward, the baffle causes one end of the movable component to move, and the other end of the movable component moves in the opposite direction to drive the valve core to move, thereby opening the liquid outlet.

[0009] In this solution, during the closing process of the filter basket, the filter basket body moves, causing the movable component to contact the baffle. As the filter basket body moves, the baffle causes the movable component to move. Due to the lever principle, the valve core moves, and the valve core opens the liquid outlet, thereby opening the filter basket and allowing the internal liquid to flow out of the filter basket. This allows the residual liquid in the filter basket to flow out and into the water receiving tray of the machine body, preventing pollution of the indoor environment.

[0010] Preferably, a fixing block is provided at the lower end of the filter basket body, and a fixing hole is provided on the fixing block, and the valve core is disposed in the fixing hole;

[0011] The lower end of the filter basket body is provided with a cover, the cover is provided with a fixing groove, the fixing block is provided in the fixing groove, the movable component is also provided in the fixing groove, and the bottom of the cover is provided with a first through hole communicating with the fixing groove.

[0012] In this solution, the valve core can be easily fixed by setting a fixing block, and the fixing block can be sealed by setting a cover.

[0013] As a further preferred embodiment, the movable component includes a rocker section and a sleeve section. The sleeve section is sleeved on the fixed block. The rocker section is provided on one side of the sleeve section. The rocker section is provided with a support rod as a fulcrum supporting the filter basket body. A second through hole is opened on one side wall of the cover, through which the rocker section passes.

[0014] In this design, a rocker section is used to raise or lower the sleeve section, which in turn raises or lowers the valve core, thereby sealing or opening the liquid outlet.

[0015] As a further preferred embodiment, the sleeve portion is provided with a mounting groove, and the valve core is provided with a connecting lug, which is located within the mounting groove.

[0016] In this design, a connecting ear is provided to facilitate lifting the valve core when the sleeve is raised.

[0017] As a further preferred embodiment, one side of the retaining rib is provided with a first inclined surface, which cooperates with the rocker portion to drive the rocker portion to move.

[0018] In this design, the first inclined surface gradually increases its contact with the rocker plate during the movement of the filter basket, thus slowly pressing the rocker plate and opening the valve core. The outlet hole is opened just as the filter basket reaches its position, preventing liquid from flowing out and contaminating the table surface if the outlet hole is opened during the movement of the filter basket.

[0019] As a further preferred embodiment, a sliding groove is provided on the outer peripheral wall of the fixing block, and the sliding groove allows the connecting lug to slide.

[0020] In this design, the movement of the connecting ear can be avoided when the sleeve part moves the connecting ear.

[0021] As a further preferred embodiment, the valve core includes a core body and a support column, the support column being disposed at the middle position of the core body, and the connecting lug being disposed on the outer peripheral wall of the core body.

[0022] As a further preferred embodiment, the support column is provided with a silicone valve plate, which is used to seal or open the liquid outlet hole.

[0023] In this solution, by setting a silicone valve plate, the liquid outlet can be better sealed so that the liquid inside will not flow out when it is not opened.

[0024] As a further preferred embodiment, the core body has a receiving cavity, and the core body has a third through hole communicating with the receiving cavity.

[0025] In this design, the liquid can be temporarily contained by setting up a receiving cavity, and the liquid can be easily discharged by setting up a third through hole.

[0026] As a further preferred embodiment, a spring is sleeved on the outer side of the support column, and the two ends of the spring are respectively connected to the upper wall of the fixing hole and the bottom wall of the receiving cavity.

[0027] In this solution, by setting a spring, after the cooperation between the baffle and the rocker plate is released, the valve core is reset under the action of the spring rebound force, thereby re-blocking the liquid outlet.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the beneficial effects that this specification can achieve include at least the following:

[0030] (1) During the closing process of the filter basket, the filter basket body moves, causing the movable component to contact the baffle. During the movement of the filter basket body, the baffle causes the movable component to move. Due to the lever principle, the valve core moves, and the valve core opens the liquid outlet hole, thereby opening the filter basket and allowing the internal liquid to flow out of the filter basket. This allows the residual liquid in the filter basket to flow out and into the water receiving tray of the machine body, preventing pollution of the indoor environment.

[0031] (2) By setting the rocker section, the sleeve section is raised or lowered, thereby raising or lowering the valve core, thus sealing or opening the liquid outlet.

[0032] (3) By setting the first inclined surface to gradually increase the contact with the rocker plate during the movement of the filter basket, the rocker plate is pressed slowly, thereby slowly opening the valve core. After the filter basket moves to the position, the liquid outlet is opened just in time to prevent the liquid from flowing out and contaminating the table surface during the movement of the filter basket.

A first inclined surface 111 is provided on one side of the baffle 11, and the first inclined surface 111 cooperates with the rocker portion 31 to drive the rocker portion 31 to move.

[0055] Furthermore, as a preferred embodiment, a sliding groove 28 is provided on the outer peripheral wall of the fixing block 22, and the sliding groove 28 allows the connecting ear 41 to slide.

[0056] Furthermore, in a preferred embodiment, the valve core 4 includes a core body 42 and a support column 43. The support column 43 is located at the middle of the core body 42, and the connecting lug 41 is provided on the outer peripheral wall of the core body 42. A silicone valve plate 44 is provided on the support column 43, which is used to seal or open the liquid outlet 21. A receiving cavity 45 is formed on the core body 42, and a third through hole 46 communicating with the receiving cavity 45 is formed on the core body 42. A spring 47 is sleeved on the outer side of the support column 43, and the two ends of the spring 47 are respectively connected to the upper wall of the fixing hole 23 and the bottom wall of the receiving cavity 45.

[0057] Specifically, in this embodiment, the filter basket body 2 is connected to the machine body 1. The machine body 1 is provided with a baffle 11. The baffle 11 is provided with a first inclined surface 111, which makes the baffle 11 wedge-shaped. The lower end of the filter basket body 2 is provided with a liquid outlet hole 21. The lower end of the filter basket body 2 is integrally provided with a fixing block 22. The fixing block 22 is provided with a fixing hole 23 and the fixing hole 23 communicates with the liquid outlet hole 21. A valve core 4 is installed in the fixing hole 23. The lower end of the filter basket body 2 is provided with a cover 24. The cover 24 is detachably connected to the filter basket body 2 by bolts. The cover 24 is provided with a fixing groove 25. The fixing block 22 is located in the fixing groove 25. The fixing groove 25 is also provided with a movable component 3. The movable component 3 is sleeved on the fixing block 22. The bottom of the cover 24 is provided with a first through hole 26 communicating with the fixing groove 25.

[0058] Specifically, in this embodiment, the valve core 4 includes a core body 42 and a support column 43. The support column 43 is located in the middle of the core body 42 and passes through the liquid outlet 21 inside the filter basket body 2. A silicone valve plate 44 is provided on the support column 43, which is used to seal or open the liquid outlet 21. A connecting lug 41 is provided on the outer peripheral wall of the core body 42, and a sliding groove 28 is provided on the outer peripheral wall of the fixing block 22 for the connecting lug 41 to slide. A receiving cavity 45 is provided on the core body 42, and a third through hole 46 is provided on the core body 42 that communicates with the receiving cavity 45. Liquid flows out from the liquid outlet 21 into the receiving cavity 45 and flows out through the third through hole 46. A spring 47 is sleeved on the outer side of the support column 43, and the two ends of the spring 47 are respectively connected to the upper wall of the fixing hole 23 and the bottom wall of the receiving cavity 45. When the outlet hole 21 is opened, the spring 47 is stretched. After the thrust on the valve core 4 is removed, the spring 47 returns to its original position, causing the valve core 4 to return to its original position.

[0059] Specifically, in this embodiment, the movable component 3 includes a rocker section 31 and a sleeve section 32. The sleeve section 32 is sleeved on the fixing block 22. The rocker section 31 is provided on the side of the sleeve section 32 near the baffle 11 of the body 1. The rocker section 31 is provided with a support rod 33 as a fulcrum for supporting the filter basket body 2. A second through hole 27 is opened on one side wall of the cover 24, through which the rocker section 31 passes. A mounting groove 34 is opened on the sleeve section 32, and the connecting ear 41 is provided in the mounting groove 34.

[0060] Specifically, in this embodiment, during the closing process of the filter basket, the filter basket body 2 moves upward, causing one end of the rocker plate portion 31 to contact the baffle 11. During the movement of the filter basket body 2, the wedge baffle 11 slowly drives one end of the rocker plate portion 31 to move downward. Because the support rod 33 forms a lever principle, the other end of the rocker plate portion 31 and the sleeve portion 32 move upward and tilt up. Also, because the mounting groove 34 of the sleeve portion 32 cooperates with the connecting ear 41 of the valve core 4, the connecting ear 41 is driven to move upward, thereby driving the valve core 4 to move upward. When the valve core 4 moves upward, the silicone valve plate 44 moves upward, thereby opening the liquid outlet 21. The liquid flows into the receiving cavity 45 through the liquid outlet 21 and then flows out from the third through hole 46. Also, because of the first through hole 26, it can flow directly into the water receiving tray of the machine body 1 at the lower end of the filter basket body 2. When the filter basket is closed, the liquid outlet 21 of the filter basket body 2 is opened, and the liquid inside the filter basket body 2 can freely flow into the coffee cup. Even if the coffee cup is removed, the residual liquid in the basket can drip into the water tray below without dripping onto the indoor countertop and causing contamination. When the filter basket is open, the liquid outlet 21 of the filter basket body 2 is out of the water tray collection range. If the filter basket drips liquid out again, it will contaminate the countertop. However, since the pry plate is separated from the baffle 11, under the action of the spring 47, the valve core 4 moves downward, causing the silicone valve plate 44 to move downward, thereby sealing and automatically closing the liquid outlet 21. The liquid inside the filter basket body 2 can no longer flow out, thus preventing contamination.

[0061] Specifically, in this embodiment, during the closing process of the filter basket, the filter basket body 2 moves, causing the movable component 3 to contact the baffle 11. During the movement of the filter basket body 2, the baffle 11 causes the movable component 3 to move. Due to the lever principle, the valve core 4 moves, and the valve core 4 opens the liquid outlet 21, thereby opening the filter basket and allowing the internal liquid to flow out of the filter basket. This allows the residual liquid in the filter basket to flow out and into the water receiving tray of the machine body 1, preventing pollution of the indoor environment.

[0062] Specifically, in this embodiment, the fixing block 22 can be used to easily fix the valve core 4, and the cover 24 can be used to seal the fixing block 22. The rocker arm 31 can be used to raise or lower the sleeve part 32, thereby raising or lowering the valve core 4 to seal or open the liquid outlet 21. The connecting lug 41 can be used to easily lift the valve core 4 when the sleeve part 32 is raised.

[0063] Specifically, in this embodiment, by setting the first inclined surface 111 to gradually increase its contact with the rocker plate portion 31 during the movement of the filter basket, the rocker plate portion 31 is pressed slowly, thereby gradually opening the valve core 4. After the filter basket moves into position, the liquid outlet hole 21 is opened just in time to prevent the liquid outlet hole 21 from opening during the movement of the filter basket and causing liquid to flow out and contaminate the table surface.

[0064] Specifically, in this embodiment, the sliding groove 28 prevents the connecting ear 41 from moving when the sleeve portion 32 moves. The silicone valve plate 44 better seals the liquid outlet 21, preventing liquid from flowing out when not in use. The receiving cavity 45 temporarily accommodates the flowing liquid, and the third through hole 46 facilitates liquid drainage. The spring 47, after the engagement between the baffle 11 and the rocker plate 31 is released, resets the valve core 4 under the spring's rebound force, thus re-blocking the liquid outlet 21.
