Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and specifically relates to a sliding cover applied to a feeding bucket and a snow melting machine. Background Art

[0002] A snow melting machine, also known as a slush machine, is a professional equipment integrating high-efficiency stirring and rapid freezing technologies, and is widely used in beverage production, the catering industry and the food processing industry. The snow melting machine can quickly convert raw materials such as fruit juice, dairy products, ice cubes and various additives into a slush-like beverage with a delicate, smooth and refreshing taste, such as smoothies and milkshakes, through a precisely designed stirring system and refrigeration system. In this process, the snow melting machine not only ensures the full mixing and uniform distribution of the raw materials, but also precisely controls the temperature to keep the beverage cold while retaining the freshness and nutrition of the raw materials.

[0003] In the design of existing snow melting machines, as a key component for accommodating food ingredients, a feeding port is generally provided at the top of the feeding bucket for convenient addition of food ingredients. However, in order to maintain the cleanliness of the internal environment of the machine and the hygiene and safety of the food ingredients, a dust-proof cover is usually installed on the feeding port to block the feeding port and prevent dust and foreign objects from entering. However, during actual use, the user needs to remove the dust-proof cover and place it aside to perform feeding. During this process, the dust-proof cover is extremely easy to be contaminated with bacteria, and when the dust-proof cover is covered again, the bacteria may be brought into the feeding bucket, thus posing a threat to the hygiene and safety of the food ingredients and becoming a major hidden danger affecting food quality and consumer health.

[0004] The present utility model is studied and proposed in view of the deficiencies of the existing technology. Summary of the Utility Model

[0005] In view of the problem that the dust-proof cover on the existing feeding bucket needs to be removed and placed aside during user feeding, and during this process, the dust-proof cover is extremely easy to be contaminated with bacteria, and when the dust-proof cover is covered again, the bacteria are easily brought into the feeding bucket, thus posing a threat to the hygiene and safety of the food ingredients, the technical solution adopted by the present utility model to solve its technical problems is as follows:

[0006] A sliding cover applied to a feeding bucket, comprising a feeding bucket housing, an opening for feeding materials provided on the feeding bucket housing, a sliding cover covering the opening, and a connecting mechanism provided between the feeding bucket housing and the sliding cover. The sliding cover moves relative to the feeding bucket housing through the connecting mechanism to open or close the opening.

[0007] Further, the connecting mechanism includes a slide rail located on the feeding bucket housing and a slide groove located on the sliding cover and slidably connected to the slide rail.

[0008] Further, a first plane and a second plane connected to the first plane are provided on the slide rail. The first plane and the second plane are obliquely connected to form an inverted corner, and a third plane corresponding to the second plane is provided on the side of the sliding cover close to the slide rail.

[0009] Further, the slide rail includes a first slide rail and a second slide rail located on one side of the first slide rail, and the opening is located between the first slide rail and the second slide rail.

[0010] Further, the sliding cover has a radian A, and a radian B is provided between the first slide rail and the second slide rail. The absolute value of the difference between the radian A and the radian B is less than 20.

[0011] Further, the radian A is equal to the radian B.

[0012] Further, the length of the slide rail is L1, the length of the opening close to the slide rail side is L2, and the length of the chute is L3. L1 > L3 > L2.

[0013] Further, a limiting portion for preventing the sliding cover from detaching from the slide rail is provided on the slide rail.

[0014] Further, the sliding cover is made of plastic material.

[0015] The present utility model further provides a snow melting machine, which includes a machine body, and the machine body includes the sliding cover applied to the loading bucket as described above.

[0016] The beneficial effects of the present utility model are as follows:

[0017] By covering a sliding cover for blocking the opening on the loading bucket housing in the present utility model, the sliding cover can move relative to the loading bucket housing through a connecting mechanism. When the user needs to put food ingredients into the opening, the user only needs to move the sliding cover relative to the loading bucket housing by hand. At this time, the sliding cover opens the opening and the sliding cover is located on the loading bucket housing, which is beneficial to reducing the risk of the sliding cover being contaminated by external bacteria or dust. Compared with the traditional removable cover, the contact area and time between the sliding cover and the external environment, such as the tabletop, hands, etc. are effectively reduced. When the user needs to close the opening, the user only needs to move the sliding cover located on the loading bucket housing to close the opening with the sliding cover, effectively solving the problem that the dust-proof cover on the existing loading bucket needs to be taken off and placed aside when the user feeds the material. During this process, the dust-proof cover is extremely easy to be contaminated by bacteria, and when the dust-proof cover is covered again, the bacteria are easily brought into the loading bucket, thus posing a threat to the hygienic safety of the food ingredients.

[0024] The following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings.

[0025] Such as Figures 1 to 5 A sliding cover applied to a loading bucket, including a loading bucket housing 1, an opening 2 for feeding materials provided on the loading bucket housing 1, a sliding cover 3 covering the opening 2, a connecting mechanism 4 provided between the loading bucket housing 1 and the sliding cover 3, and the sliding cover 3 moves relative to the loading bucket housing 1 through the connecting mechanism 4 so as to open or close the opening 2;

[0026] In the present utility model, a sliding cover for covering the opening is provided on the loading bucket housing, and the sliding cover can move relative to the loading bucket housing through the connecting mechanism. When the user needs to put food materials into the opening, the user only needs to move the sliding cover relative to the loading bucket housing by hand. At this time, the sliding cover opens the opening and is located on the loading bucket housing, which is beneficial to reducing the risk of the sliding cover being contaminated by external bacteria or dust. Compared with the traditional removable cover, the contact area and time between the sliding cover and the external environment, such as the tabletop, hands, etc. are effectively reduced. When the user needs to close the opening, the user only needs to move the sliding cover located on the loading bucket housing to close the opening with the sliding cover, effectively solving the problem that the dust-proof cover on the existing loading bucket needs to be taken off and placed aside when the user feeds materials, and the dust-proof cover is extremely easy to be contaminated by bacteria during this process, and it is easy to bring bacteria into the loading bucket when the dust-proof cover is covered again, thereby threatening the health and safety of the food materials.

[0027] Optionally, in some embodiments, the connecting mechanism 4 includes a hinge shaft located on one side of the opening 2 and provided on the loading bucket housing 1, and a hinge hole located on the sliding cover 3 and hinged to the hinge shaft, so that the sliding cover 3 can rotate around the hinge shaft to open or close the opening 2.

[0028] Optionally, in some embodiments, the connecting mechanism 4 includes a spring fixing seat located on one side of the opening 2 and fixedly arranged on the charging bucket housing 1, a card slot located on the sliding cover 3 and slidably connected to the spring fixing seat, and a spring located on the spring fixing seat. One end of the spring abuts against the spring fixing seat, and the other end of the spring abuts against the sliding cover 3. Under normal circumstances, the spring exerts pressure on the sliding cover 3 to keep the sliding cover 3 closed. When the user needs to feed materials, the user exerts a thrust on the sliding cover 3, the spring undergoes elastic deformation, and the sliding cover 3 moves relative to the spring fixing seat to open the opening 2. When the user releases the hand, the thrust disappears, the spring restores its elastic deformation, and the spring pushes the sliding cover 3 to reset to close the opening 2.

[0029] Optionally, in some embodiments, the connecting mechanism 4 includes a sliding bead assembly located on one side of the opening 2 and arranged on the charging bucket housing 1, and a sliding groove located on the sliding cover 3. The sliding bead assembly is slidably connected to the sliding groove so that the sliding cover 3 can move relative to the charging bucket housing 1 to open or close the opening 2.

[0030] Further, as a preferred but non-limiting manner of the present invention, the connecting mechanism 4 includes a slide rail 41 located on the charging bucket housing 1 and a slide groove 42 located on the sliding cover 3 and slidably connected to the slide rail 41. The slide rail 41 and the slide groove 42 are slidably matched so that the sliding cover 3 can move relative to the charging bucket housing 1 to open or close the opening 2.

[0031] As Figures 1 to 5 shown, the connecting mechanism 4 includes a slide rail 41 located on the charging bucket housing 1 and a slide groove 42 located on the sliding cover 3 and slidably connected to the slide rail 41;

[0032] Further, the user can open or close the opening 2 on the charging bucket housing 1 by simply sliding the sliding cover 3, without complex operation steps or tools, which is beneficial to improving the convenience of using the device.

[0033] Further, the sliding connection between the slide rail 41 and the slide groove 42 can provide a smooth and resistance-free sliding operation. The smooth surface on the slide rail 41 and the precise fit in the slide groove 42 are beneficial to reducing friction and jamming phenomena during the movement of the sliding cover 3, so that the operation of the sliding cover 3 when opening or closing the opening 2 is more smooth and fluent.

[0034] Further, the sliding connection between the slide rail 41 and the slide groove 42 helps to ensure that the sliding cover 3 is stable and does not deviate from the track during the movement. The slide rail 41 can provide guidance for the movement track of the sliding cover 3 to avoid unnecessary swinging or deviation of the sliding cover 3 when opening or closing the opening 2.

[0035] Further, the sliding connection between the slide rail 41 and the slide groove 42 can reduce wear caused by friction, which is beneficial to extending the service life of the connecting mechanism 4 and maintaining long-term stable performance.

[0036] As Figures 1 to 5 shown, the slide rail 41 is provided with a first plane 411 and a second plane 412 connected to the first plane 411. The first plane 411 and the second plane 412 are inclined and connected to form an inverted corner. A third plane 31 corresponding to the second plane 412 is provided on one side of the sliding cover 3 close to the slide rail 41;

[0037] Specifically, the setting of the inverted corner makes the assembly process of the chute 42 and the slide rail 41 simpler. The inverted corner enables the second plane 412 and the third plane 31 to be in sliding contact. During the assembly process, the user only needs to gently snap, and the assembly of the chute 42 and the slide rail 41 can be completed. Compared with the traditional slide rail with a "7"-shaped cross-section, when assembling the chute 42, relatively precise alignment and a large insertion force are often required because the right angle of the "7"-shaped cross-section is likely to form a jamming point during assembly, and the user needs to carefully adjust the angle and position of the chute 42 to ensure that it can smoothly slide into the slide rail 41. This process is not only time-consuming and laborious but also may cause damage to the chute 42 or the slide rail 41 due to improper operation.

[0038] Furthermore, the setting of the inverted corner can provide natural guidance and auxiliary positioning when the chute 42 is docked with the slide rail 41. Due to the sliding contact between the second plane 412 and the third plane 31, the chute 42 can naturally slide down along the inclined plane of the inverted corner and align to the correct position of the slide rail 41.

[0039] Furthermore, the setting of the inverted corner makes the docking method of the chute 42 and the slide rail 41 unique. Due to the inclined plane and the inclination angle of the inverted corner, the chute 42 can easily distinguish the installation direction and avoid misinstallation.

[0040] Furthermore, the setting of the inverted corner enables the chute 42 to have a certain self-adjusting ability during the assembly process. Due to the inclined angle of the inverted corner, the chute 42 can slightly adjust its position during the assembly process to ensure accurate docking with the slide rail 42.

[0041] As Figures 1 to 5 shown, the slide rail 41 includes a first slide rail 51 and a second slide rail 52 located on one side of the first slide rail 51. The opening 2 is located between the first slide rail 51 and the second slide rail 52;

[0042] Furthermore, the first slide rail 51 and the second slide rail 52 jointly provide double support for the sliding cover 3, making the sliding cover 3 more stable during movement and facilitating reducing the possibility of the sliding cover 3 shaking and deviating during movement.

[0043] Furthermore, the provision of the first slide rail 51 and the second slide rail 52 provides a clear sliding path and guidance for the sliding cover 3, enabling the sliding cover 3 to remain stable and smooth during movement, which is conducive to reducing jamming and friction phenomena.

[0044] Furthermore, the first slide rail 51 and the second slide rail 52 can help disperse the load borne by the sliding cover 3 during sliding, which is conducive to reducing the pressure on a single slide rail 41 and effectively extending the service life of the device.

[0045] Furthermore, the first slide rail 51 and the second slide rail 52 are symmetrically arranged.

[0046] Furthermore, the symmetrically arranged first slide rail 51 and second slide rail 52 can evenly distribute the weight and pressure of the sliding cover 3, effectively preventing the sliding cover 3 from shifting or tilting during sliding. The symmetrical layout of the first slide rail 51 and the second slide rail 52 can ensure the stability of the sliding cover 3 during sliding, which is conducive to reducing swing or friction caused by uneven loads.

[0047] Furthermore, the symmetrically arranged first slide rail 51 and second slide rail 52 not only enhance the functional performance of the device but also improve the aesthetic appearance of the device. The symmetrical arrangement gives a harmonious and unified aesthetic feeling visually, which helps to improve the overall appearance quality of the product.

[0048] As Figures 1 to 5 shown, the sliding cover 3 is provided with a radian A, and a radian B is provided between the first slide rail 51 and the second slide rail 52, and the absolute value of the difference between the radian A and the radian B is less than 20;

[0049] Furthermore, when the sliding cover 3 is closed, due to the high matching degree of the radian A and the radian B, the sliding cover 3 can fit more closely between the first slide rail 51 and the second slide rail 52.

[0050] Furthermore, the radian setting is not only aesthetically pleasing but also can enhance the overall structural stability of the charging bucket housing 1 to a certain extent. The curved sliding cover 3, the first slide rail 51, and the second slide rail 52 can better disperse external impacts and stresses, which is conducive to reducing the risk of damage caused by direct collision or stress concentration.

[0051] Furthermore, the difference between the radian A and the radian B is less than 20, so that the fit between the sliding cover 3 and the slide rail 41 is more delicate, thereby enhancing the overall aesthetic appearance. The precise matching of the radians can make the device look more coordinated and high-end.

[0052] Optionally, in some embodiments, the absolute value of the difference between the arc A and the arc B is 5. Although the arc A and the arc B do not completely match, the difference of 5 degrees can provide a certain adaptability, allowing a small error between the sliding cover 3 and the sliding rail 41; secondly, the arc difference of 5 degrees can prevent the sliding cover 3 from contacting the sliding rail 41 too closely, which is conducive to reducing initial friction and operational resistance.

[0053] Optionally, in some embodiments, the absolute value of the difference between the arc A and the arc B is 10, and a larger arc difference provides a larger tolerance range, which is suitable for manufacturing tolerances or assembly errors between the sliding cover 3 and the sliding rail 41; secondly, the arc difference of 10 degrees can be adjusted to a certain extent during the assembly process so that the sliding cover 3 can adapt to slightly different arcs of the sliding rail 41.

[0054] Furthermore, as a preferred embodiment of the present invention but not a limitation, the absolute value of the difference between the arc A and the arc B is 0, and the arcs between the slide cover 3 and the slide rail 41 are completely consistent, which can ensure that the slide cover 3 has uniform contact when sliding on the slide rail 41, which is beneficial to reducing friction and wear; secondly, the slide cover 3 will not deviate or tilt when sliding on the slide rail 41, which is beneficial to providing higher stability and accuracy.

[0055] like Figures 1 to 5 Said radian A is shown to be equal to radian B;

[0056] Furthermore, the setting of the arc A equal to the arc B enables the sliding cover 3 to move along a smooth track during the opening and closing process, which is conducive to reducing friction and resistance, not only making the operation easier and more labor-saving, but also extending the service life of the sliding cover 3 and the sliding rail 41.

[0057] Furthermore, the arc A is equal to the arc B, which can ensure that the contact surface between the slide cover 3 and the slide rail 41 fits perfectly, so that the slide cover 3 fits perfectly on the slide rail 41, thereby forming a more uniform contact area.

[0058] like Figures 1 to 5 The length of the slide rail 41 is L1, the length of the opening 2 close to the slide rail 41 is L2, the length of the slide slot 42 is L3, and L1>L3>L2;

[0059] Furthermore, the length L1 of the slide rail 41 is greater than the length L3 of the slide groove 42, which is beneficial to provide a longer guide surface so that the slide cover 3 is more stable during the sliding process. Even if the length L3 of the slide groove is shorter, the longer length of the slide rail 41 can ensure the stable sliding of the slide cover 3, which is beneficial to reduce the risk of swinging and shaking.

[0060] Furthermore, the setting of L1 > L3 enables the sliding cover 3 to fully open the opening 2. The sliding cover 3 is still supported and restricted by the slide rail 41, and the sliding cover 3 will not accidentally disengage from the chute 42, effectively avoiding the risk of loss of the sliding cover 3, especially in occasions where the sliding cover needs to be frequently opened and closed. Secondly, since the sliding cover 3 is always located on the slide rail 41, the direct contact between the sliding cover 3 and the external environment is greatly reduced, which helps to prevent the sliding cover 3 from being contaminated by bacteria and dust.

[0061] Furthermore, the length L3 of the chute 42 is equal to the length of the sliding cover 3. The setting of L3 > L2 enables the sliding cover 3 to fully cover the opening 2. When the sliding cover 3 slides to the position where it completely blocks the opening 2, it can effectively prevent the opening 2 from being exposed to the external environment, effectively avoiding the entry of dust, insects, moisture or other pollutants into the interior of the charging bucket housing 1.

[0062] As Figures 1 to 5 shown, the slide rail 41 is provided with a limiting portion for preventing the sliding cover 3 from disengaging from the slide rail 41;

[0063] Optionally, in some embodiments, the limiting portion includes a first limiting portion located at one end of the slide rail 41 away from the opening 2.

[0064] Optionally, in some embodiments, the limiting portion includes a second limiting portion located at one end of the slide rail 41 close to the opening 2.

[0065] Furthermore, as a preferred mode rather than a limitation of the present invention, the limiting portion includes a first limiting portion located at one end of the slide rail 41 away from the opening 2 and a second limiting portion located at one end of the slide rail 41 close to the opening 2.

[0066] Optionally, in some embodiments, the limiting portion is a limiting bump provided at the end of the slide rail 41. When the sliding cover 3 slides to a specific position of the slide rail 41, the setting of the limiting bump can block the further sliding of the sliding cover 3, thereby preventing the sliding cover 3 from disengaging from the slide rail 41.

[0067] Optionally, in some embodiments, the limiting portion is a limiting convex column provided at the end of the slide rail 41 and extending in the direction of the opening 2. When the sliding cover 3 slides to a specific position of the slide rail 41, the setting of the limiting convex column can block the further sliding of the sliding cover 3, thereby preventing the sliding cover 3 from disengaging from the slide rail 41.

[0068] As Figures 1 to 5 shown, the sliding cover 3 is made of plastic material;

[0069] Furthermore, the sliding cover 3 has a certain elasticity. During the process of assembling the chute 42 and the slide rail 41, the sliding cover 3 undergoes elastic deformation, so that the sliding cover 3 can be installed on the charging bucket housing 1.

[0070] Optionally, in some embodiments, the sliding cover 3 is made of polypropylene, which is a semi-crystalline thermoplastic with high impact resistance, wear resistance, chemical corrosion resistance, and heat resistance.

[0071] Optionally, in some embodiments, the sliding cover 3 is made of polyethylene terephthalate, which is a highly transparent plastic material with good chemical corrosion resistance, weather resistance, and mechanical strength.

[0072] As Figures 1 to 5 shown in the snowmelt machine, it includes a body 6, and the body 6 includes the sliding cover applied to the loading bucket as described above;

[0073] Specifically, by providing a sliding cover applied to the loading bucket on the body 6, when it is necessary to put food ingredients into the opening 2, the user can control the relative position of the sliding cover 3 through a simple sliding action, thereby opening the opening 2 without using complex tools or excessive force, thus improving work efficiency; secondly, while the sliding cover 3 completely opens the opening 2, the sliding cover 3 is still supported and restricted by the slide rail 41, and the sliding cover 3 will not accidentally disengage from the chute 42, effectively avoiding the risk of losing the sliding cover 3, especially in occasions where the sliding cover 3 needs to be opened and closed frequently; finally, since the sliding cover 3 is always located on the slide rail 41, the direct contact between the sliding cover 3 and the external environment is greatly reduced, which helps to prevent the sliding cover 3 from being contaminated by bacteria and dust.

[0074] The implementation manner of this embodiment is as follows:

[0075] A sliding cover applied to a charging bucket, comprising a charging bucket housing 1, an opening 2 for discharging materials provided on the charging bucket housing 1, a sliding cover 3 covering the opening 2, and a connecting mechanism 4 provided between the charging bucket housing 1 and the sliding cover 3. The connecting mechanism 4 includes a slide rail 41 located on the charging bucket housing 1 and a slide groove 42 located on the sliding cover 3 and slidably connected to the slide rail 41. The sliding connection between the slide rail 41 and the slide groove 42 enables the sliding cover 3 to move relative to the charging bucket housing 1. Under normal circumstances, the sliding cover 3 closes the opening 2, and the sliding cover 3 can completely block the opening 2 to prevent dust, insects, moisture or other pollutants from entering the interior of the charging bucket housing 1. When the user needs to discharge materials, only a simple sliding action is required to control the position of the sliding cover 3 relative to the charging bucket housing 1, thereby opening the opening 2, without the need to use complex tools or excessive force. When the sliding cover 3 completely opens the opening 2, the sliding cover 3 is still supported and restricted by the slide rail 41, and the sliding cover 3 will not accidentally disengage from the slide groove 42, effectively avoiding the risk of loss of the sliding cover 3. At the same time, the sliding cover 3 is always located on the slide rail 41, which greatly reduces the direct contact between the sliding cover 3 and the external environment, helping to prevent the sliding cover 3 from being contaminated with bacteria and dust. This effectively solves the problem that the dust-proof cover on the existing charging bucket needs to be removed and placed aside when the user feeds materials. During this process, the dust-proof cover is extremely easy to be contaminated with bacteria, and it is easy to bring bacteria into the charging bucket when the dust-proof cover is covered again, thus posing a threat to the hygienic safety of the food materials. The sliding cover 3 is provided with a radian A, and the slide rail 41 includes a first slide rail 51 and a second slide rail 52 located on one side of the first slide rail 51. A radian B is provided between the first slide rail 51 and the second slide rail 52, and the radian A is equal to the radian B, which is beneficial to ensuring uniform contact when the sliding cover 3 slides on the slide rail 41 and helps to reduce friction and wear.

[0076] The above only further illustrates the technical content of the present invention with examples to make it easier for readers to understand, but does not mean that the implementation mode of the present invention is limited to this. Any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
