Description

Technical Field

[0001] This utility model relates to the field of cup lid technology, and in particular to a press-type temperature display cup lid. Background Technology

[0002] The press-type temperature display cup lid is an existing cup lid, but its function is far more than just a simple "open and close". It can also read the temperature of the liquid in the cup. Usually, the opening and closing of the drinking spout is controlled by pressing the button or a specific area on the lid.

[0003] The publication number CN222194656U, entitled "A Press-Type Cup Lid with Temperature Display Function," proposes a solution to the problem that existing press-type thermos cups cannot display their internal temperature.

[0004] The use of a temperature display on the lid of a thermos is an existing technology. However, these lids require pressing to use before drinking. While the lid has a drinking spout near the edge, this spout is mostly exposed, making it susceptible to contamination. This contaminants are then ingested along with the liquid. Therefore, improvements are needed. Currently, the press-type temperature display lid has a complex structure and comes into contact with the liquid. When the thermos contains different liquids, residual liquid and dirt can accumulate inside the lid. Furthermore, the lid is only filled with liquid when drinking; otherwise, the liquid remains inside the cup, creating a humid and airy environment inside the lid. Prolonged consumption of this environment could potentially harm one's health. Utility Model Content

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes a press-type temperature display cup lid. Please refer to [link / reference]. Figures 1-10Specifically, the current press-type temperature display cup lid has a relatively complex structure and comes into contact with liquid. When different liquids are contained in the thermos, residual liquid and dirt will be generated inside the temperature display cup lid. The inside of the cup lid is prone to a humid environment with air, which can affect human health if consumed for a long time. Based on this, a press-type temperature display cup lid is proposed, including an outer layer 1. A temperature display cover 2 is installed inside the outer layer 1 near the upper end. A temperature probe 21 extending downward is installed at the lower end of the temperature display cover 2. A pressing and undulating component 3 is installed on the outside of the temperature display cover 2. The pressing and undulating component 3 automatically engages when the temperature display cover 2 is pressed to control the opening and closing of the temperature display cup lid. The pressing and undulating component 3 is threadedly connected to the outer layer 1. An elastic support member 4 is installed inside the outer layer 1. The elastic support member 4 is used to control the rebound of the pressing and undulating member 3 and to maintain a seal with the outer layer 1. An openable channel 7 is formed between the outer layer 1, the pressing and undulating component 3, and the elastic support component 4. When the pressing and undulating component 3 is pressed, the channel 7 opens; otherwise, the channel 7 closes.

[0025] Specifically, the pressing and undulating component 3 is an existing structure. By manually pressing the temperature display cover 2, the temperature display cover 2 will move downward and remain in the downward position. Subsequent pressing will reset it. The internal elastic support component 4 is used to cooperate with the pressing and undulating component 3. The channel 7 allows the inside of the cup body to pass through the cup lid, and controls the opening and closing under the action of the pressing and undulating component 3.

[0026] like Figures 3-6 As shown, the pressing and undulating component 3 includes a first fastening layer 31, a second fastening layer 32, a third fastening layer 33, and a fourth fastening layer 34; The inner part of the outer layer 1 has a threaded sleeve 11. The second fastening layer 32 is threadedly connected to the threaded sleeve 11. The first fastening layer 31 is fastened inside the second fastening layer 32. The third fastening layer 33 and the fourth fastening layer 34 are rotatably sleeved on the outer wall of the temperature probe 21. The third fastening layer 33 is located at the upper end of the fourth fastening layer 34. When the pressing undulating part 3 is pressed, the first fastening layer 31 can cooperate with the fourth fastening layer 34.

[0027] Specifically, the temperature display cover 2 is used to display the temperature, and the temperature probe 21 detects the temperature of the cup body downwards, which is existing technology. The first fastening layer 31, the second fastening layer 32, the third fastening layer 33, and the fourth fastening layer 34 are all existing technologies. The inner wall of the fastening layer 31 has an integral outer meshing ring 311. The lower end of the outer meshing ring 311 has inclined teeth. Every two teeth at the lower end of the outer meshing ring 311, there is an upwardly extending groove 312. The lower end of the third snap-fit ​​layer 33 has an internal gear ring 331, which is fitted inside the outer meshing ring 311. The outer wall of the third snap-fit ​​layer 33 extends into the extension groove 312 to prevent the third snap-fit ​​layer 33 from rotating. The outer wall of the fourth snap-fit ​​layer 34 has an integrally formed locking block 341 with an inclined upper end. The upper end of the locking block 341 can cooperate with the internal gear ring 331 and the outer meshing ring 311. The internal gear ring 331 and the outer meshing ring 311 are staggered. When the internal gear ring 331 moves downward, it can push the locking block 341 to lock into the next outer meshing ring 311.

[0028] When the temperature display cover 2 is pressed down, both the third and fourth fastening layers 33 and 34 move downwards. When the locking block 341 moves downwards out of the outer meshing ring 311, it will rotate under the pushing action of the inner toothed ring 331, causing the locking block 341 to deflect to a certain extent. Then the temperature display cover 2 is loosened, so that the locking block 341 engages with the next outer meshing ring 311 or the extension groove 312. It should be noted that when the locking block 341 engages with the outer meshing ring 311, it is in a pressing state, and when it engages with the extension groove 312, it is in an upward reset state, that is, the channel 7 is opened and closed. It should be noted that since the outer wall of the third fastening layer 33 extends into the extension groove 312, the third fastening layer 333 will not rotate when it moves up and down. When the third fastening layer 33 moves downwards, its inner toothed ring 331 can engage with the locking block 341, and the locking block 341 can deflect along the inner toothed ring 331.

[0029] like Figures 3-5 As shown, the inner side of the outer sleeve 1 threaded sleeve 11 is integrally fitted with a limiting ring 12, the elastic support component 4 includes a support tube 41 fitted inside the limiting ring 12, the temperature probe 21 is fitted inside the support tube 41 and the two are sealed, and a sealing element 45 is fixed on the outside of the support tube 41 to seal with the limiting ring 12. A spring 44 is supported on the limiting ring 12. A stop block 42 is fixed on the outer wall of the support tube 41. A cover 43 is attached to the support tube 41 and abuts against the lower end of the stop block 42. The cover 43 abuts against the lower end of the spring 44. The spring 44 is used to control the reset of the pressing and undulating component 3.

[0030] Specifically, under the action of spring 44, the cover 43 is supported upward, the cover 43 presses against the block 42, the lower sealing cover 47 is lifted upward, and the channel 7 is closed. At the same time, spring 46 is compressed. When the temperature display cover 2 is pressed down, under the action of the rubber connector 49, the support tube 41 moves downward, spring 44 is compressed, and the lower sealing cover 47 moves downward under the action of spring 46, opening the channel 7.

[0031] like Figure 2 and Figure 4 As shown, the cover 43 is cap-shaped and is used to fasten the upper part of the spring 44.

[0032] Specifically, the cover 43 is pressed downward by the abutment 42. Since the cover 43 is cap-shaped and has a hole in the middle for the support tube 41 to pass through, the abutment 42 supports the upper end of the cover 43 when in use. When disassembling, the abutment 42 rotates a short distance and can be directly removed from the extended cover 43. The hole on the cover 43 is circular in the middle and fan-shaped on the side.

[0033] like Figures 3-5 As shown, the elastic support component 4 also includes a second spring 46 and a lower closing cover 47; Spring 2 46 is abutted against the lower end of the limiting ring 12. The lower sealing cover 47 is fastened to the lower part of the support tube 41. The lower sealing cover 47 abuts against the lower end of spring 2 46. The upper end of the lower sealing cover 47 has an integral support ring 48. The support ring 48 is used to fit spring 2 46. The spring coefficient of spring 1 44 is greater than that of spring 2 46. The lower sealing cover 47 is provided with a rubber connector 49, which is used to squeeze and seal the temperature probe 21. The rubber connector 49 is engaged with the lower end of the support tube 41 and forms a seal with the lower sealing cover 47.

[0034] Specifically, the rubber connector 49 is used to clamp and limit the temperature probe 21, and also engages with the support tube 41. A seal is formed between the rubber connector 49 and the lower sealing cover 47 to prevent liquid from moving upwards through the gap. The second spring 46 exerts a squeezing action on the lower sealing cover 47, pushing it downwards. When the temperature display cover 2 is pressed, it ensures that the lower sealing cover 47 moves downwards, opening the channel 7. It should be noted that the spring constant of the first spring 44 is greater than that of the second spring 46, so that when the first spring 44 returns to its original position, the second spring 46 can be compressed. Furthermore, under the action of the first spring 44 and the second spring 46, the temperature display cover will not feel loose or wobble, preventing slight displacement of internal parts and the generation of noise during shaking.

[0035] like Figure 8 As shown, the interior of the outer layer 1 has a downward penetrating opening 13, which coincides with the channel 7 and is part of the channel 7. like Figure 5 As shown, an outer sealing layer 471 is fixed on the outside of the lower sealing cover 47. When the pressing and undulating component 3 is reset, the outer sealing layer 471 seals with the lower end of the outer jacket layer 1. When the pressing and undulating component 3 is pressed, there is a gap between the outer sealing layer 471 and the lower end of the outer jacket layer 1, which allows liquid to enter the channel 7. When the lower sealing cover 47 is reset, the outer sealing layer 471 seals with the lower end of the outer jacket layer 1, thus sealing the channel 7.

[0036] like Figure 5As shown, the upper end of the lower sealing cover 47 has a sealing groove 472, and the inner side of the outer jacket 1 near the lower end has an integrally formed inlaid ring 473 extending downward. The inlaid ring 473 slides in fit with the sealing groove 472, and the outer wall of the inlaid ring 473 has a rubber layer for sealing.

[0037] With the setting of the inlay ring 473, when the channel 7 is opened, the upper part of the lower sealing cover 47 is in a closed state, which makes it difficult for liquid to penetrate inward and reduces the residual liquid inside the temperature display cup cover.

[0038] like Figures 7-10 As shown, the threaded sleeve 11 is fitted with a protective layer 6, which is used to cover the channel 7. The protective layer 6 includes an outer ring 61 fixedly fitted to the outside of the threaded sleeve 11 and an inner ring 64 fitted inside the outer ring 61. The outer ring 61 has a drinking spout 62 communicating with the channel 7. The outer ring 61 is in contact with the inner wall of the outer sleeve 1 and has a locking point 63 on its upper edge. The inner ring 64 is semi-open and can be rotated to abut against the locking point 63 and is used to control the opening and closing of the drinking spout 62.

[0039] Specifically, the inner ring 64 in the protective layer 6 is rotatable, which can control the opening and closing of the drinking spout 62. The inner ring 64 can also block dust and impurities, preventing them from moving onto the drinking channel 7. Meanwhile, since the outer ring 61 is fixedly fitted to the outside of the threaded sleeve 11, the protective layer 6 can be removed after the second fastening layer 32 is disassembled, making it easy to clean the areas on the temperature display cup lid where bacteria can easily grow.

[0040] like Figure 10 As shown, the outer wall of the outer jacket 1 near the lower end has a notch 14, and a filter cover 5 is fitted onto the lower end of the outer jacket 1. The filter cover 5 has an inwardly protruding notch 51 on its side, which is used to cooperate with the notch 14 so that the filter cover 5 and the outer jacket 1 can be detachably snapped together.

[0041] Specifically, the filter cover 5 can be installed and removed by the engagement of the recess 51 and the notch 14, and is also easy to clean.

[0042] Working principle: When opening the temperature display cup lid, first press down on the temperature display cover 2, causing it to move downwards. The pressure-adjusting component 3 then limits the temperature display cover 2, maintaining it in the pressed state. Figure 5 The middle arrow indicates the direction of liquid movement. When drinking water, the water moves in the direction of the arrow, and the water is safe to drink directly. However, even if the temperature display cover 2 is reset, the upper part of channel 7 is still exposed to the outside and directly affected by the external environment. Furthermore, channel 7 is in a humid state for a long time, making it easier for dust to adhere and for bacteria to grow. Therefore, a protective layer 6 is provided. The inner ring 64 in the protective layer 6 can be rotated. By rotating the inner ring 64, the drinking spout 62 can be opened and closed, making it less likely for dust and impurities to fall directly to the water flow area, thus minimizing the direct consumption of dust and impurities.

[0043] Furthermore, by rotating the second fastening layer 32 to disengage it from the threaded sleeve 11, the second fastening layer 32 and some of its internal structures can be directly removed upwards. Similarly, the protective layer 6, which is fitted onto the outside of the threaded sleeve 11, can also be removed upwards, separating the outer ring 61 and the inner ring 64 for direct disassembly and cleaning. It should be noted that the temperature probe 21 will also move upwards. Figure 4 As shown, the rubber connector 49 needs to be separated from the temperature probe 21 so that the temperature probe 21 can be taken out directly upwards. The function of the rubber connector 49 is to limit the support tube 41 and the temperature probe 21. After the rubber connector 49 is disassembled, the support tube 41 and the temperature probe 21 can be separated directly. At the same time, the support tube 41 is rotated so that the abutment 42 on its outer wall rotates, which can be separated from the cover 43 and can move downwards from the cover 43, so that the entire support tube 41 can move downwards. The lower sealing cover 47 at the lower end can also be removed, which is convenient for subsequent cleaning of the inside of the stack.

[0044] like Figure 5 As shown, the sealing groove 472 and the inlay ring 473 can prevent liquid from moving to the position of spring 46 as much as possible when the lower sealing cover 47 moves downward or resets. The sealing element 45 also achieves a sealing effect. When drinking water, the temperature display cup lid is in an inclined state, which makes it difficult for the internal liquid to seep upward from the sealing element 45.
