Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet and its screwing structure. Background Technique

[0002] The general water output of direct drinking water equipment on the market is about 2L / min, so there are not many requirements for the faucet and its valve structure. However, with the rise of water purifiers equipped with pressure buckets, the water output can be increased to 9L / min. Moreover, with the pressure bucket as a buffer, the prepared direct drinking water in the pressure bucket will be given priority. The water purifier will not start immediately every time water is used, but will start after detecting that the pressure value in the pressure bucket is lower than the set value. Reducing the startup frequency is particularly important for reverse osmosis direct drinking machines because a part of water is used to flush the reverse osmosis membrane every time it starts, which solves the problem of stale water and wastes water resources. In fact, 9L / min is not the limit of the water output from the pressure bucket, and it can even reach 18L / min. However, if the faucet is opened to 18L / min, the pressure in the pressure bucket will instantly drop to the startup pressure value of the water purifier. Although the water output flow is large, the significance of using the pressure bucket as a buffer to reduce the startup frequency of the water purifier is lost, and users do not need such a large water output every time.

[0003] Therefore, it is usually necessary for users to control the opening and closing angle of the faucet valve by themselves to control the water output. However, it is often inconvenient and inaccurate for users to control the water output. Summary of the Utility Model

The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0054] Below in conjunction with Figures 1 to 6 , the faucet and its screwing structure 100 provided by the embodiments of the present application will be described in detail through specific embodiments.

[0055] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1It is a schematic structural diagram of the faucet provided by the present utility model; Figure 2 It is an exploded schematic diagram of the faucet provided by the present utility model; Figure 3 It is a schematic structural diagram of the screwing structure provided by the present utility model; Figure 4 It is an exploded schematic diagram of the screwing structure provided by the present utility model. The screwing structure 100 provided by one embodiment of the present utility model is applied to the faucet 200. The screwing structure 100 is arranged on the base of the faucet 200. The screwing structure 100 includes an upper cover 10, a rotating shaft 20 and a screwing assembly 30. One end of the rotating shaft 20 is connected to the upper cover 10; the screwing assembly 30 includes a rotating disk 31, a chassis 32 and a resistance member 33. The rotating disk 31 and the chassis 32 are arranged oppositely. The chassis 32 is arranged inside the faucet 200. The rotating disk 31 is arranged on the rotating shaft 20 or inside the upper cover 10. The other end of the rotating shaft 20 passes through the chassis 32 and is connected to the valve 50. The resistance member 33 is used to apply a force for the rotating disk 31 and the chassis 32 to squeeze each other; wherein, the opposite surfaces of the chassis 32 and the rotating disk 31 are provided with slope portions, so that the rotating disk 31 can be driven by the upper cover 10 to rotate, and thus the slope portion of the rotating disk 31 can move relative to the slope portion of the chassis 32, and further the rotating disk 31 can slide along the rotating shaft 20 to compress the resistance member 33.

[0056] In other embodiments, different from the above embodiments, the position of the resistance member 33 is switched from above the rotating disk 31 to below the chassis 32. At this time, the rotating disk 31 is fixed on the rotating shaft 20 or inside the upper cover 10, and the chassis 32 is slidably arranged vertically inside the faucet 200. In this way, when the chassis 32 and the rotating disk 31 rotate relative to each other, the chassis 32 can slide vertically to compress the resistance member 33, and the invention purpose can also be achieved. Therefore, it can be understood that any up-and-down switching or simple adjustment of the positions of the resistance member 33, the chassis 32 and the rotating disk 31 is within the protection scope of the present utility model without creative labor.

[0057] The upper cover 10 is connected to the rotating shaft 20, and the rotating shaft 20 and the rotating disk 31 are engaged with each other. When the user twists the upper cover 10, the upper cover 10 can drive the rotating shaft 20 to rotate, so that the rotating shaft 20 can drive the rotating disk 31 to rotate horizontally.

[0058] The screwing assembly 30 includes a rotating disk 31, a chassis 32 and a resistance member 33. The rotating disk 31 and the chassis 32 are arranged corresponding to each other and the rotating disk 31 and the chassis 32 are adapted to each other.

[0059] In the initial state, when the valve 50 is not opened, the rotating disk 31 and the chassis 32 are in contact with each other, the resistance member 33 is in a normal uncompressed state, and at this time, the slope portion of the rotating member and the slope portion of the chassis 32 are not in contact.

[0060] During the process of opening the valve 50, the upper cover 10 is rotated. The upper cover 10 can drive the rotary shaft 20 to rotate horizontally. At this time, the rotary shaft 20 can drive the rotary disk 31 clamped thereto to rotate horizontally. The slope portion of the rotary disk 31 gradually approaches the slope portion of the chassis 32 and moves on the slope portion of the chassis 32. Then, when the rotary disk 31 rotates horizontally, it can receive an upward acting force from the slope portion of the chassis 32. Thus, the rotary disk 31 can move vertically along the rotary shaft 20 while rotating horizontally. At this time, the rotary disk 31 can compress the resistance member 33, and the resistance member 33 can form a reaction force opposite to that of the rotary disk 31. Through such a setting, when the user opens the valve 50 of the faucet 200, with the rotation angle of the upper cover 10, the resistance member 33 can form a resistance to feedback to the user the current open state of the valve 50. Thus, the user can control the water output by himself by controlling the opening and closing angle of the faucet valve 50.

[0061] In some more specific examples, the chassis 32 is arranged on the base 40 of the faucet 200 and is fixed to the base 40 of the faucet 200. When the upper cover 10 is rotated, the rotary disk 31 rotates synchronously with the rotary shaft 20. At this time, the slope portion of the rotary disk 31 will contact the slope portion of the chassis 32. By fixedly connecting the chassis 32 and the base 40, it is possible to prevent the chassis 32 from rotating after receiving the acting force from the contact with the rotary disk 31. Through such a setting, preventing the chassis 32 and the rotary disk 31 from rotating synchronously can ensure that the rotary disk 31 can move vertically upward while rotating.

[0062] In some more specific examples, through holes are provided on both the chassis 32 and the base 40, and the area of the through holes is slightly larger than the cross-sectional area of the rotary shaft 20. Through such a setting, when the rotary shaft 20 passes through the chassis 32 and the base 40, if the rotary shaft 20 rotates following the upper cover 10, the rotary shaft 20 will not apply a rotational acting force to the base 40 and the chassis 32.

[0063] In another embodiment, a first clamping portion is provided on the inner wall of the upper cover 10, and a second clamping portion corresponding to the first clamping portion is provided on the outer side of the rotating shaft 20. The rotating disk can be fixed in the upper cover 10 and can rotate synchronously with the upper cover through the mutual cooperation of the first clamping portion and the second clamping portion. During the process of opening the valve 50, the upper cover 10 is rotated, and the upper cover 10 can drive the rotating disk 31 clamped thereto to rotate horizontally. The slope portion of the rotating disk 31 gradually approaches the slope portion of the chassis 32 and moves on the slope portion of the chassis 32. Since the rotating disk 31 is clamped to the upper cover, the chassis 32 will rotate horizontally at this time and can receive a downward acting force from the slope portion of the rotating disk 31, so that the chassis 32 can move vertically downward along the rotating shaft 20 while rotating horizontally. At this time, the chassis 32 can compress the resistance member 33, and the resistance member 33 can form an opposite acting force on the chassis 32. Through such a setting, when the user opens the valve 50 of the faucet 200, as the rotation angle of the upper cover 10 rotates, the resistance member 33 can form a resistance to feedback to the user that the valve 50 is being opened at this time, so that the user can control the opening and closing angle of the faucet valve 50 by himself to control the water output.

[0064] In the above embodiment, one end of the rotating shaft 20 is connected to the upper cover 10, and the other end is connected to the valve 50. Thus, when the upper cover 10 is twisted, the valve 50 can be rotated through the rotating shaft 20, and then the valve 50 is opened or closed.

[0065] Please refer to Figure 4 and Figure 5 , Figure 4 which is an exploded view of the screwing structure provided by the present utility model; Figure 5 which is an exploded view of the rotating disk and the chassis of the screwing structure provided by the present utility model. In some embodiments, the rotating disk 31 is provided with a first guiding surface 311, a first convex surface 316 and a first slope surface 312, and the chassis 32 is provided with a second guiding surface 321, a second convex surface 326 and a second slope surface 322; the first guiding surface 311 and the first slope surface 312 are connected; the second guiding surface 321 and the second slope surface 322 are connected; the first convex surface 316 is in mutual fit with the second guiding surface 321, and the second convex surface 326 and the first guiding surface 311 are in mutual fit; the first slope surface 312 and the second slope surface 322 are oppositely arranged, and the first guiding surface 311 and the second guiding surface 321 are oppositely arranged; when the faucet 200 is in the state where the valve 50 is closed, there is a gap between the first slope surface 312 and the second slope surface 322 to form a space for the rotation of the rotating disk 31.

[0066] Among them, when the faucet 200 is in the valve 50 closed state, a gap is formed between the first slope 312 and the second slope 322, and the first guide surface 311 and the second guide surface 321 are used to guide the first convex surface 316 and the second convex surface 326 to slide respectively. The first guide surface 311 of the rotating disk 31 and the first guide surface 311 of the chassis 32 are set correspondingly. When the valve 50 is opened, the rotating disk 31 is rotating, and the first convex surface 316 of the rotating disk 31 slides on the second guide surface 321, and at this time, the first convex surface 316 of the rotating disk 31 will follow the rotating disk 31 to rotate on the second guide surface 321 of the chassis 32 to the second slope 322. Through such a setting, when the valve 50 is gradually opened, the movement between the rotating disk 31 and the chassis 32 is between the first convex surface 316 and the first guide surface 326, and at this time, the rotating disk 31 is not subjected to the force from the chassis 32, and the user can perceive that the valve 50 is open at a small degree.

[0067] After the rotating disk 31 continues to rotate, the gap between the first slope 312 and the second slope 322 gradually becomes smaller until the first slope 312 and the second slope 322 collide with each other. Then continue to rotate the upper cover 10, the first slope 312 of the rotating disk 31 can move on the second slope 322, because the chassis 32 is fixed on the base 40, the rotating disk 31 can have an upward trend on the second slope 322 while rotating, so that the rotating disk 31 compresses the resistance member 33, and the resistance member 33 forms a resistance. Through such a setting, when the valve 50 further opens the valve 50 to increase the flow rate, the movement between the rotating disk 31 and the chassis 32 is to move between the first slope 312 and the second slope 322. At this time, the rotating disk 31 moves in the vertical direction after receiving the force from the chassis 32, and the rotating disk 31 compresses the resistance member 33. The user can clearly perceive that the resistance increases when the upper cover 10 is rotated at this time, and the valve 50 opening degree increases at this time.

[0068] In some embodiments, the rotating disk 31 is also provided with a first reset surface 313, the first guide surface 311 is extended approximately in the horizontal direction, and the first reset surface 313 is extended approximately along the vertical surface; the first reset surface 313 is arranged at one end of the first guide surface 311 away from the first slope surface 312; the chassis 31 is also provided with a second reset surface 323, the first reset surface 313 is extended approximately in the vertical surface; the second reset surface 323 is arranged at one end of the second guide surface 321 away from the second slope surface 322; the first reset surface 313 and the second reset surface 323 are relatively horizontally arranged; when the faucet 200 is in the valve 50 closed state, the first reset surface 313 and the second reset surface 323 abut against each other.

[0069] The first reset surface 313 and the second reset surface 323 can be horizontal planes and are relatively horizontally arranged, so that the first reset surface 313 and the second reset surface 323 can be mutually attached.

[0070] The first reset surface 313 and the first guiding surface 311 can be perpendicularly arranged and connected to each other. The second reset surface 323 and the second guiding surface 321 can be perpendicularly arranged and connected to each other. When the valve 50 is in the closed state, the first reset surface 313 and the second reset surface 323 are mutually attached to form a relative abutting force. If the rotating disk 31 rotates in the opposite direction (the direction of opening the valve 50 is the correct direction), the first reset surface 313 and the second reset surface 323 abut against each other, thereby restricting the rotating disk 31 from rotating in the opposite direction.

[0071] In this embodiment, if the user needs to close the valve 50 after using the faucet 200, the upper cover 10 can be twisted in the opposite direction. At this time, the first reset surface 313 and the second reset surface 323 gradually approach each other, and when the first reset surface 313 and the second reset surface 323 come into contact with each other, the valve 50 is closed. Through such a setting, it can be clearly sensed that the valve 50 is closed, and at this time, since the first reset surface 313 and the second reset surface 323 abut against each other, the user cannot continue to rotate the valve 50 in the opposite direction, preventing damage to the valve 50.

[0072] In some embodiments, the rotating disk 31 is further provided with a first transition surface 315, and the first transition surface 315 is substantially horizontally extended along the first slope surface 312; the chassis 32 is further provided with a second transition surface 325, and the second transition surface 325 is substantially horizontally extended along the second slope surface 322; the first transition surface 315 and the second transition surface 325 are relatively arranged.

[0073] The first transition surface 315 is extended at the end of the first slope surface 312, and the second transition surface 325 is extended at the end of the second slope surface 322. When the rotating disk 31 rotates, after the first slope surface 312 rises to the end of the second slope surface 322 and the rotating disk 31 continues to rotate, the first transition surface 315 and the second transition surface 325 come into contact with each other. At this time, the opening degree of the valve 50 is the largest, and after continuing to move, the first blocking surface 314 and the second blocking surface 324 abut against each other to restrict the rotating disk 31 from continuing to rotate.

[0074] In this embodiment, the first transition surface 315 and the second transition surface 325 are arranged horizontally and correspondingly. When the first slope surface 312 rises to the end of the second slope surface 322, the first transition surface 315 and the second transition surface 325 are in horizontal contact. At this time, the rotating disk 31 no longer moves in the vertical direction during rotation, and the resistance provided by the resistance member 33 to the rotating disk 31 remains unchanged. Through such an arrangement, the user can clearly feel that the maximum opening of the valve 50 has been reached at this time.

[0075] Specifically, the first transition surface 315 and the second transition surface 325 can be arranged along the horizontal direction. Such an arrangement can make the rotating disk 31 and the bottom plate 32 more stable when they are in contact and move relative to each other, so that the user can operate the valve switch conveniently.

[0076] In some embodiments, the rotating disk 31 is also provided with a first blocking surface 314, which is located at the end of the first slope surface 312; the chassis 32 is also provided with a second blocking surface 324, which is arranged at the end of the second slope surface 322; the first blocking surface 314 and the second blocking surface 324 are arranged opposite to each other.

[0077] A first blocking surface 314 is provided at the end of the first slope surface 312, and the first blocking surface 314 is located at the end of the first transition surface 315 and extends vertically approximately along the first transition surface 315; a second blocking surface 324 is provided at the end of the second slope surface 322, and the second blocking surface 324 is located at the end of the second transition surface 325 and extends vertically approximately along the second transition surface 325.

[0078] When the valve 50 is opened, the rotating disk 31 rotates, and the gap between the first slope 312 and the second slope 322 gradually decreases until the first slope 312 and the second slope 322 collide with each other. Then the upper cover 10 is rotated continuously, and the first slope 312 of the rotating disk 31 can move on the second slope 322, and the first blocking surface 314 and the second blocking surface 324 are close to each other. Since the first blocking surface 314 and the second blocking surface 324 are arranged relative to each other, the rotating disk 31 can drive the first blocking surface 314 to rotate to fit with the second blocking surface 324, so that a contact force is formed between the first blocking surface 314 and the second blocking surface 324 to limit the rotating disk 31 from continuing to rotate. In this embodiment, when the first blocking surface 314 and the second blocking surface 324 fit, the rotating disk 31 cannot continue to rotate, and the user can clearly feel that the upper cover 10 cannot continue to rotate forward to increase the opening of the valve 50, and the flow rate of the valve 50 is the maximum at this time.

[0079] See also Figure 6 , Figure 6It is a schematic structural view of the upper cover of the screwing structure provided by the present utility model. In some embodiments, a limiting post 11 is provided at the top of the inner wall of the upper cover 10, and the limiting post 11 faces the rotating disc 31.

[0080] A limiting post 11 is provided on the inner wall of the upper cover 10, and the limiting post 11 and the rotating disc 31 are oppositely arranged. When the rotating disc 31 rotates, it can move vertically upward along the rotating shaft 20. When the rotating disc 31 rises to the moving distance, the rotating disc 31 can contact the surface of the limiting post 11, and the limiting post 11 can limit the rotating disc 31 from continuing to move upward.

[0081] In some embodiments, a receiving cavity 111 is formed by hollowing out the limiting post 11, and the rotating shaft 20 is clamped in the receiving cavity 111.

[0082] The shape of the receiving cavity 111 is the same as the shape of the rotating shaft 20. For example: if the shape of the limiting post 11 is a hexagonal prism, the shape of the receiving cavity 111 is a cavity adapted to the hexagonal prism at this time.

[0083] By hollowing out the receiving cavity 111 in the limiting post 11 and receiving the rotating shaft 20 in the receiving cavity 111, the rotating shaft 20 can rotate synchronously with the limiting post 11. Moreover, since the limiting post 11 is provided on the upper cover 10, when the user rotates the upper cover 10, the synchronous rotation of the rotating shaft 20 and the upper cover 10 can be realized.

[0084] In some embodiments, the resistance member 33 is a spring, the spring is sleeved on the rotating shaft 20, and both ends of the spring respectively abut against the rotating disc 31 and the upper cover.

[0085] In this embodiment, when the rotating disc 31 rotates, the gap between the first slope 312 and the second slope 322 gradually decreases until the first slope 312 and the second slope 322 abut against each other. Then, when the upper cover 10 is continuously rotated, the first slope 312 of the rotating disc 31 can move on the second slope 322. Since the chassis 32 is fixed on the base 40, the rotating disc 31 can tend to rise on the second slope 322 while rotating, so that the rotating disc 31 compresses the spring, and the spring can form a resistance due to being compressed. And when the rotating disc 31 rises, the spring can be further compressed to form a greater resistance. Through such a setting, the user can clearly perceive that the resistance increases and changes when rotating the upper cover 10 at this time, so as to perceive that the opening degree of the valve 50 increases.

[0086] In some other embodiments, the resistance member 33 is a spring. The spring is sleeved on the rotating shaft 20, and two ends of the spring respectively abut against the chassis 32 and the base 40 of the faucet. At this time, the rotating disk 31 is snap-connected in the upper cover 10. When the upper cover 10 is rotated, the upper cover 10 can drive the rotating disk 31 snap-connected thereto to rotate horizontally. The slope portion of the rotating disk 31 gradually approaches the slope portion of the chassis 32 and moves on the slope portion of the chassis 32. Since the rotating disk 31 and the upper cover 10 are snap-connected to each other, the chassis 32 will rotate horizontally at this time and can receive a downward acting force from the slope portion of the rotating disk 31, so that the chassis 32 can move vertically downward along the rotating shaft 20 while rotating horizontally. When the chassis 32 moves downward, the spring can be compressed by the chassis 32 to form a resistance, and when the chassis 32 is descending, the spring can be further compressed to form a greater resistance. Through such an arrangement, the user can clearly perceive that the resistance increases and changes when the upper cover 10 is rotated at this time, so that the user can perceive that the opening degree of the valve 50 increases.

[0087] In some embodiments, the resistance member 33 includes two magnets that repel each other magnetically, and the two magnets that repel each other magnetically are respectively located on the upper cover and the rotating disk 31.

[0088] In this embodiment, after the rotating disk 31 rotates, the gap between the first slope 312 and the second slope 322 gradually becomes smaller until the first slope 312 and the second slope 322 abut against each other. Then, when the upper cover 10 is continuously rotated, the first slope 312 of the rotating disk 31 can move on the second slope 322. Since the chassis 32 is fixed to the base 40, the rotating disk 31 can have an upward trend on the second slope 322 while rotating, so that the rotating disk 31 drives one of the magnets to move towards the other magnet that repels it, and the two magnets that repel each other gradually approach to form a resistance. And when the rotating disk 31 is rising, the two magnets gradually approach to form a greater resistance. Through such an arrangement, the user can clearly perceive that the resistance increases and changes when the upper cover 10 is rotated at this time, so that the user can perceive that the opening degree of the valve 50 increases.

[0089] In some other embodiments, a screwing structure 100 is further provided and applied to a faucet 200 . The screwing structure 100 is disposed on a base 40 of the faucet 200 . The screwing structure 100 includes an upper cover 10 , a rotating shaft 20 and a screwing assembly 30 . One end of the rotating shaft 20 is connected to the upper cover 10; the screwing assembly 30 includes a rotating disk 31, a chassis 32 and a resistance member 33, the rotating disk 31 and the chassis 32 are arranged opposite to each other, the chassis 32 is arranged in the faucet 200, the rotating disk 31 is slidably arranged on the rotating shaft 20 along the vertical direction, the other end of the rotating shaft 20 passes through the chassis 32 and is connected to the valve 50, and the resistance member 33 is used to apply a force of mutual compression between the rotating disk 31 and the chassis 32; wherein, the chassis 32 is circumferentially provided with a first concave-convex surface on one side facing the rotating disk 31, and the rotating disk 31 is circumferentially provided with a second concave-convex surface on one side facing the chassis 32, so that when the rotating disk 31 rotates, the first concave-convex surface cooperates with the second concave-convex surface, thereby driving the rotating disk 31 to move vertically along the rotating shaft to compress the resistance member.

[0090] In this embodiment, the first concavoconvex surface and the second concavoconvex surface can cooperate with each other, and when the rotating disk 31 rotates, the convex surface of the first concavoconvex surface can rotate to the convex surface of the second concavoconvex surface, and the rotating disk 31 moves vertically along the rotating shaft 20 to get closer to the upper cover. Through such a setting, the rotating disk 31 can rotate vertically while rotating to compress the resistance member 33, and the user will be resisted by the resistance member 33 when twisting the upper cover.

[0091] In some specific examples, since the surfaces of the first concave-convex surface and the second concave-convex surface are both composed of concave surfaces and convex surfaces, when the first concave-convex surface moves relatively along the second concave-convex surface, the rising height of the rotating disk 31 changes, so as to compress the resistance member 33 to different degrees.

[0092] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Another embodiment of the utility model further provides a faucet 200, comprising the above-mentioned screw structure 100; as well as a base 40, a valve 50 and a water outlet 60. The base 40 and the bottom plate 32 are mutually engaged, and the rotating shaft 20 is passed through the bottom plate 32 and the base 40; the valve 50 is connected to the other end of the rotating shaft 20; the water outlet 60 and the valve 50 are mutually connected, and the valve 50 is used to open or close the water outlet 60.

[0093] The base 40 is connected to the chassis 32 of the screw structure 100. The rotating shaft 20 is passed through the base 40 and then connected to the valve 50, so that the rotating shaft 20 can drive the valve 50 to rotate. When the valve 50 rotates, the water outlet 60 can be gradually opened or closed, thereby controlling the water output of the faucet 200.

[0094] In this embodiment, during the process of opening the valve 50, the upper cover 10 is rotated. The upper cover 10 can drive the rotating shaft 20 to rotate horizontally. At this time, the rotating shaft 20 can drive the rotating disk 31 clamped thereto to rotate horizontally. The sloped portion of the rotating disk 31 gradually approaches the sloped portion of the chassis 32 and moves on the sloped portion of the chassis 32. Then, when the rotating disk 31 rotates horizontally, it can receive an upward acting force from the sloped portion of the chassis 32. Thus, the rotating disk 31 can move vertically along the rotating shaft 20 while rotating horizontally. At this time, the rotating disk 31 can compress the resistance member 33, and the resistance member 33 can form a reaction force opposite to that of the rotating disk 31. Through such a setting, when the user opens the valve 50 of the faucet 200, as the rotation angle of the upper cover 10 changes, the resistance member 33 can form a resistance to feedback to the user that the valve 50 is being opened at this time. Thus, the user can control the opening and closing angle of the faucet valve 50 by himself to control the water output.

[0095] It should be specifically noted that the faucet 200 provided in the embodiment of the present invention only shows the part related to the technical problem to be solved by the embodiment of the present invention. It can be understood that the faucet 200 provided in the embodiment of the present invention further includes other structures for realizing the functions of the faucet 200, including but not limited to water pipe connection structures, water quality detection structures, etc.
