Description

Technical Field

[0001] This utility model relates to the field of cup washing technology, and in particular to a faucet and its cup washing device drainage structure. Background Technology

[0002] A cup washer is a device used to clean cups. It comes in various types and designs. The most common type uses a pressing action to generate high-pressure water jets in multiple directions to rinse cups. The operation is very simple and does not require the use of brushes or other tools, making the cleaning process efficient and convenient.

[0003] In existing technologies, the pressing shaft of a cup washer is usually located on the circumference of its spout. Users must place the cup almost coaxially in the center of its water tray to press the cup washer to make water flow; otherwise, the water flow is small or even non-existent. Furthermore, this structure requires a large space under the spout (i.e., inside the cup washer), making it difficult to design the cup washer to be very thin. As a result, the cup washer product is relatively thick and tends to occupy space in the height direction. Especially when the cup washer is installed side by side with the faucet or directly on the faucet, it is easy for it to bump into the faucet's spout and "interfere" with each other during the washing of longer cups, resulting in a poor user experience.

Detailed Implementation

[0035] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0036] refer to Figures 1 to 5 The diagram illustrates the first embodiment of this utility model, which is a drainage structure for a cup washer 100. It includes a support platform 101, a water-passing body 102, a nozzle 104, a button 105, a return spring 106, and a water-receiving tray 107. The water-passing body 102 is disposed within the support platform 101, and a cup-washing water path 1021 is provided therein. A shaft tube 1031 is provided on the upper surface of the water-passing body 102, extending upwards through the upper surface of the support platform 101. The nozzle 104 is installed at the water outlet end of the water-passing body 102 and passes through the shaft tube 1031. The button 105 extends along the length of the cup washer 100, with one end sleeved on the shaft tube 1031. The button 105 moves up and down relative to the water-passing body 102 along the shaft tube 1031, so that the other end of the button 105 is used to actuate the opening and closing of the cup-washing water path 1021. The water-receiving tray 107 is rotatably sleeved on the circumference of the shaft tube 1031.

[0037] Through the above solution, the first embodiment, by setting an elongated button 105 extending along the length of the cup washer 100, increases the relative area between the button 105 and the water tray 107. This allows the user to apply force to the button 105 by pressing the water tray 107 from any position, thereby achieving a linkage to open the cup washing water path 1021. The user's pressing of the water tray 107 is no longer limited to the area around the nozzle 104, making operation more convenient and providing a better user experience. At the same time, the elongated button 105 makes the opening and closing mechanism of the cup washing water path 1021 and the nozzle 104 more interconnected. A certain distance is formed between them. When the cup washer 100 is installed side by side with the faucet or directly on the faucet, the center of the water tray 107 (i.e. the position of the nozzle 104) can avoid the water outlet of the faucet to avoid possible interference when washing cups. Furthermore, by setting a detachable water tray 107 (which can be directly removed from the shaft tube 1031), different specifications of water trays can be selected according to user needs, which increases the freedom of product configuration. The water tray 107 can also be used to prevent water splashing during washing and guide water to the sink on the countertop.

[0038] The following shows the structural details of the first embodiment: The aforementioned cup washer 100 also includes a piston rod 108 and a piston spring 109 disposed within the water-passing body 102; the upper end of the piston rod 108 extends out of the water-passing body 102 and is connected to one end of the button 105, and under the action of the piston spring 109, blocks the input and output ends of the cup washing water path 1021, thereby realizing the opening and closing of the cup washing water path 1021.

[0039] The aforementioned cup washer 100 also includes a rotating seat 103 with a shaft tube 1031. The rotating seat 103 is elongated (rectangular, elliptical, teardrop-shaped, etc.), and its length direction is consistent with the length direction of the cup washer 100. It is fixed to the upper surface of the water-passing body 102 by means of screw locking, snap-fit ​​connection, etc. The button 105 matches the shape of the rotating seat 103, and one or a pair of return springs 106 are provided between one end of the button 105 and the rotating seat 103. Long snaps 1051 are provided on both sides of the front and rear ends of the button 105. The rotating seat 103 is provided with snap holes 1032 corresponding to the positions of the long snaps 1051, allowing the long snaps 1051 to move through and hook. The water-passing body 102 can be provided with guide grooves or guide holes corresponding to the positions of the snap holes 1032. Thus, the button 105 and the rotating seat 103 can be moved together, and the button 105 can be prevented from disengaging from the rotating seat 103 due to the elastic force of the return spring 106.

[0040] This invention also improves the structure of the cup washer 100, enabling it to perform a rotating water spray cleaning function. Specifically, the cup washer 100 further includes an impeller 110; the water-passing body 102 is provided with a water outlet chamber 1022, a water outlet channel 1023, and a water inlet channel 1024, which are sequentially connected to form the aforementioned cup washing water path 1021; the peripheral surface of the water outlet chamber 1022 is provided with at least one inclined water hole 1025; the water outlet channel 1023 is arranged around the peripheral surface of the water outlet chamber 1022 and connects to the water outlet chamber through the inclined water hole 1025. 1022 is connected; the two ends of the water inlet channel 1024 are respectively connected to the water outlet channel 1023 and the water supply end of the cup washer 100 (such as the faucet valve body 300 in the following embodiment) to realize water supply to the cup washer 100; the impeller 110 is rotatably fitted in the water outlet chamber 1022 and is arranged opposite to the inclined water hole 1025; the inner end of the nozzle 104 is dynamically and rotatably fitted in the water passage body 102 and is connected to the impeller 110 for transmission, so as to realize that the nozzle 104 and the impeller 110 rotate synchronously. Therefore, the cup washer 100, through the impeller 110 set in the water-passing body 102, when the cup washer 100 is used, the water flow from the inlet channel 1024 enters the outlet channel 1023 and forms a ring water flow, and then enters the outlet chamber 1022 through the inclined water hole 1025, which drives the impeller 110 to rotate and drives the nozzle 104 to rotate synchronously, finally achieving a 360° rotating water spray state, realizing a more comprehensive cleaning of cups such as water cups 700; compared with conventional cup washer, the rotating water spray has a more comprehensive and efficient cleaning effect.

[0041] Furthermore, a first gear 1101 is provided on the circumferential surface of the impeller 110, and a second gear 1041 meshing with the first gear 1101 is provided on the inner end of the nozzle 104. The diameter of the first gear 1101 is smaller than the diameter of the blades of the impeller 110, thereby increasing the rotational torque of the impeller 110 through the first diameter difference. The transmission ratio between the first gear 1101 and the second gear 1041 is at least 1:5, thereby increasing the rotational torque of the nozzle 104 through the second transmission ratio, enabling it to overcome the frictional torque and generate rotation. The frictional force originates from the irregularly shaped sealing ring provided on the circumferential surface of the nozzle 104 to improve the dynamic sealing effect.

[0042] Meanwhile, the upper surface of the nozzle 104 is provided with a blade water outlet 1042, which is designed in a flat and narrow shape (i.e., "straight line"). Thus, the nozzle 104 can cooperate with the impeller 110 to spray 360° rotating blade water, which makes it easier to clean cups and other utensils and improves cleaning efficiency.

[0043] Secondly, to facilitate the processing and molding of the components, the aforementioned water-passing body 102 includes a split-design upper cover 102a, a base 102b, a water-passing component 102c, and a connector 102d. The connector 102d is used to install and fix the cup washer 100 (for example, in the following embodiment, the cup washer 100 is installed on a faucet). The base 102b, the water-passing component 102c, and the connector 102d are sequentially sealed and connected. The base 102b is provided with a groove 1026, and the bottom wall of the groove 1026 is provided with a boss 1027. The periphery of the boss 1027 is provided with a ring that fits against the groove 1026. The inner wall has an annular groove 1028; the upper cover 102a is sealed to the side wall of the groove 1026, so that the water outlet cavity 1022 is formed between the upper cover 102a and the boss 1027, and the water outlet channel 1023 is formed between the upper cover 102a and the annular groove 1028, and the inclined water hole 1025 is provided on the circumferential surface of the upper cover 102a; the channel between the water passage component 102c and the connecting component 102d together constitutes the water inlet channel 1024; the piston rod 108 is installed in the water passage component 102c, specifically in a dynamically sealed manner in the movable hole 1029 on the radial side of the water passage component 102c. Therefore, during production, only a groove-shaped structure needs to be formed on the base 102b, and after being tightly fitted with the upper cover 102a during installation, the corresponding cavity can be formed, making the component molding simpler and easier to demold.

[0044] Furthermore, the aforementioned cup washer 100 also includes a bottom cover 111 and a limiting plate 112; the lower surface of the support platform 101 is recessed to form an installation groove 1011, and the water-passing body 102 is installed in the installation groove 1011; the bottom cover 111 fits into the opening of the installation groove 1011 to cover the water-passing body 102; the bottom cover 111 is snap-fitted to the water-passing body 102; the limiting plate 112 is located below the movable hole 1029 and blocks the movable hole 1029, and its two ends are respectively connected and fixed in the installation groove 1011 by screws or other means. Therefore, by setting the bottom cover 111, the product's appearance is not only beautiful and clean, but the water-passing body 102 can also be quickly removed from the support platform 101 without removing the support platform 101; the limiting plate 112 can not only realize the installation and fixation of the water-passing body 102 in the support platform 101, but also block the movable hole 1029. When the limiting plate 112 is removed, it can also facilitate the replacement and cleaning of the piston rod 108.

[0045] An elastic diaphragm 113 is provided between the rotating seat 103 and the support platform 101. The edge of the elastic diaphragm 113 is clamped by the support platform 101 and the rotating seat 103 and covers the upper surface of the button 105. When the water receiving tray 107 and the button 105 are pressed, the elastic diaphragm 113 can be deformed arbitrarily.

[0046] The aforementioned water receiving tray 107 includes a rigid base 1071 disposed above the rotating seat 103, and a soft cushioning member 1072 attached to the upper surface of the rigid base 1071. Thus, the water receiving tray 107 has two layers of soft and hard material disposed on the upper and lower surfaces, which can prevent the cup from directly contacting the hard material and causing bumps and damage.

[0047] refer to Figures 6 to 9 As shown, a second embodiment of the present invention is illustrated, which is a faucet, comprising: Figures 1 to 5 The diagram shows the drainage structure of the cup washer 100, as well as the faucet body 200, faucet valve body 300, and valve core assembly 400. The faucet valve body 300 is disposed inside the faucet body 200, and a plurality of first protrusions 301 are provided on the circumferential surface of the faucet valve body 300. The cup washer 100 is disposed on the side of the faucet body 200, and the support platform 101 is rotatably fitted onto the circumferential surface of the faucet valve body 300. The cup washer water passage 1021 is connected to the water outlet end of the faucet valve body 300, and a mounting hole 10210 communicating with the cup washer water passage 1021 is provided between the two ends of the cup washer 100. The valve core assembly 400 is dynamically and rotatably fitted in the mounting hole 10210 to control the on / off state between the two ends of the cup washer water passage 10211. A plurality of second protrusions 4011 that mesh with the first protrusions 301 are provided on the circumferential surface of the end of the valve core assembly 400 exposed in the mounting hole 10210.

[0048] Through the above solution, the second embodiment has the technical effects of the first embodiment, and the cup washer 100 can rotate around the faucet valve body 300 as an axis, thereby achieving left and right swinging to avoid collisions. When the cup washer 100 swings to the side of the sink, it is not easy to accidentally touch it. Furthermore, the engagement between the first protrusion 301 and the second protrusion 4011 can achieve linkage with the valve core assembly 400 inside the cup washer 100, so that when the cup washer 100 is swinging, the valve core assembly 400 can control the opening and closing between the two ends of the cup washing water circuit 1021: when the valve core assembly 400 is in the open state, the faucet valve body 300 can supply water to the cup washer 100; when the valve core assembly 400 is in the closed state, the faucet valve body 300 cannot supply water to the cup washer 100. Therefore, the user can open and close the water inlet of the cup washer 100 by swinging the cup washer 100 left and right. In the closed state, it can prevent the user from accidentally touching the button 105 of the cup washer 100 and being wetted by high-pressure water.

[0049] The following shows the structural details of the second embodiment: The first tooth 301 on the circumference of the faucet valve body 300 and the second tooth 4011 on the circumference of the valve core assembly 400 are at least fan-shaped, that is, they do not form a complete gear. This means that after the cup washer 100 rotates a certain angle, the second tooth 4011 will disengage from the first tooth 301 and no longer mesh. At this time, the internal valve core assembly 400 will maintain the corresponding state and will not change until the cup washer 100 is swung again and the second tooth 4011 can mesh with the first tooth 301 again.

[0050] The aforementioned valve core assembly 400 is a sealed ball valve, comprising a rotating shaft 401, a sealing spring 402, and two sealing balls 403. One end of the rotating shaft 401 has the aforementioned second convex tooth 4011 on its circumferential surface, and its other end is dynamically sealed within the mounting hole 10210, and has a cross hole 4012 extending through to the circumferential surface of the rotating shaft 401. The sealing spring 402 is disposed within the cross hole 4012, with a sealing ball 403 at each end. Thus, the valve core assembly 400, through the sealing balls 403 under the elastic force of the sealing spring 402, opens or closes the communication hole 10211 between the cup washing water passage 1021 and the mounting hole 10210, thereby achieving the connection and disconnection between the two ends of the cup washing water passage 1021. As the rotating shaft 401 rotates, when the sealing ball 403 is opposite to the connecting hole 10211, it will be pushed out by the sealing spring 402 and blocked in the position of the connecting hole 10211. When the sealing ball 403 is misaligned with the connecting hole 10211, the sealing ball 403 will be pushed back by the inner wall of the mounting hole 10210 to the retracted cross hole 4012, while compressing the sealing spring 402.

[0051] Furthermore, a plurality of spring clips 4013 are provided on the end face of one end of the aforementioned rotating shaft 401. The spring clips 4013 hook onto the port of the mounting hole 10210 to achieve relative fixation between the rotating shaft 401 and the cup washer 100. The aforementioned sealing ball 403 may be made of rubber material, and its elasticity can ensure the sealing and leak-proof effect.

[0052] The second embodiment also includes a faucet valve core 500 and a handle 600; the faucet valve body 300 is provided with a first water inlet channel 302, a second water inlet channel 303, a first water outlet channel 304, and a second water outlet channel 305, and the first water inlet channel 302, the second water inlet channel 303, the first water outlet channel 304, and the second water outlet channel 305 are all connected to the surface of the faucet valve body 300 for the faucet valve core 500 to connect to; the input ends of the first water inlet channel 302 and the second water inlet channel 303 can be connected to cold and hot water sources (i.e., cold water pipes and hot water pipes), and the output ends of the first water outlet channel 304 and the second water outlet channel 305 are respectively connected to the water outlet of the faucet (i.e., the water outlet device at the bend, such as an aerator or a pull-out handle). The shower head (etc.) and the cup washer 100, i.e., the output end of the second water outlet 305, are connected to the aforementioned cup washing water outlet 1021; the faucet valve core 500 is a two-inlet, two-outlet type, which is installed inside the faucet body 200 and connected to the faucet valve body 300. Under the drive of the handle 600, it controls the flow of water from the first water inlet 302 and the second water inlet 303 to one of the first water outlet 304 and the second water outlet 305, or adjusts the proportion of the water flow to one of the first water outlet 304 and the second water outlet 305, or makes the first water inlet 302 and the second water inlet 303 disconnect from the first water outlet 304 and the second water outlet 305 to close the water circuit. The specific structure of the faucet valve core 500 has been disclosed in the applicant's authorized patent CN221003880U, which is already a public and mature prior art, and will not be described in detail here. In summary, this utility model utilizes the existing faucet valve core 500 with "two inlets and two outlets" control function and improves the structure of the faucet valve body 300. It can supply hot and cold water to the faucet outlet and also provide an additional water path for the cup washer 100. This makes the cup washer 100 attached to the faucet no longer have a single function, but also has temperature and water volume adjustment functions, making its application scenarios more extensive and meeting the diverse needs of users.

[0053] Furthermore, the circumferential surface of the aforementioned faucet valve body 300 is provided with a recessed water passage groove 306, and the water passage groove 306 and the first protruding tooth 301 are located adjacent to each other in the axial direction of the faucet valve body 300; the bottom wall of the water passage groove 306 is provided with a water outlet 307, which is connected to the second water outlet passage 305, and the faucet valve body 300 is provided with a corresponding water passage; the end of the water passage body 102 is provided with an annular sealing part 10212, the inner wall of the annular sealing part 10212 is connected to the mounting hole 10210, and the annular sealing part 10212 is dynamically and rotatably sleeved on the circumferential surface of the faucet valve body 300 and covers the water passage groove 306. This creates a waterway connecting the second water outlet 305 and the water outlet 307 between the faucet valve body 300 and the annular sealing part 10212. The faucet valve body 300 is ultimately connected to the cup washing waterway 1021. The valve core assembly 400 in the mounting hole 10210 can control the connection between the faucet valve body 300 and the cup washing waterway 1021. At the same time, a recessed water passage groove 306 is designed on the circumference of the faucet valve body 300, and then the annular sealing part 10212 closes it to form a waterway. This makes it easier to achieve the connection between the second water outlet 305 and the water outlet 307 in the waterway design.

[0054] The aforementioned faucet valve core 500 is equipped with a rocker arm 501 for connecting the handle 600.

[0055] refer to Figure 10 , Figure 11 The diagram shows a third embodiment of the present invention, which is also a faucet. Most of its structural design is the same as or similar to that of the second embodiment. The structural differences between the two are as follows: The first tooth 301 is set as a half circle, i.e., 180°, on the circumference of the faucet valve body 300; the second tooth 4011 is set as a full circle on the circumference of the valve core assembly 400. This design enables full gear transmission between the faucet valve body 300 and the valve core assembly 400. No matter how the cup washer 100 rotates, the first tooth 301 always meshes with the second tooth 4011, preventing misalignment and accelerated wear.

[0056] The valve core assembly 400 no longer includes the sealing spring 402 and the sealing ball 403, but instead includes a rotating shaft 401 and a cup switch 404. One end of the rotating shaft 401 has the aforementioned second protruding tooth 4011 on its circumferential surface, and its other end is dynamically sealed within the mounting hole 10210, and has a water passage hole 4014 extending through to the circumferential surface of the rotating shaft 401. The cup switch 404 is mounted on the circumferential surface of the rotating shaft 401, and as the rotating shaft 401 rotates, it opens or closes the connecting hole 10211 between the cup washing water passage 1021 and the mounting hole 10210, thereby achieving the connection and disconnection between the two ends of the cup washing water passage 1021. Compared to the solution using the sealing spring 402 and the sealing ball 403, the cup switch 404 has a simpler structure and provides a surface seal with the connecting hole 10211, not directly contacting the edge of the connecting hole 10211, resulting in less wear and a lower risk of failure.

[0057] In the above embodiments, conventional technical means such as O-rings and special-shaped sealing rings can be used to seal the parts that require sealing to prevent water leakage, including dynamic and static seals.

[0058] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
