Description

Technical Field

[0001] This utility model relates to the field of stirring cup technology, and more specifically, to a pressure relief structure and stirring cup that are easy to disassemble and clean. Background Technology

[0002] With the continuous improvement of residents' living standards and the upgrading of market consumption, people are paying increasing attention to healthy eating and have higher requirements for the nutritional processing of food. Against this backdrop, food processors such as food processors and juicers, as emerging upgraded consumer products in the kitchen appliance category, are gaining popularity among consumers due to their convenient and efficient food processing capabilities.

[0003] However, during the actual operation of a food blender, the high-speed rotating blades generate a large amount of heat due to intense friction and impact when cutting and pulverizing materials. This heat causes the air inside the blender to expand rapidly, creating a high-pressure environment within the sealed container. This sustained high pressure can easily cause the blender to expand and even shatter, posing a safety risk and severely impacting the reliability of the machine and the user experience.

[0004] To address this issue, while some existing mixing cup products incorporate dedicated pressure relief mechanisms, their structures are typically quite complex, leading to increased production costs. Furthermore, these pressure relief mechanisms are often difficult to disassemble for thorough cleaning, and long-term use can result in the accumulation of dirt and grime, posing hygiene risks. Utility Model Content

[0005] To address at least one of the aforementioned problems, this utility model provides a pressure relief structure that is easy to disassemble and clean, comprising a cup body and an elastic sealing element. The sealing element includes an integrally connected sealing block and a plug-in portion. The cup body has an inner cavity, and the cup body has a plug-in hole and a pressure relief hole. The plug-in portion is detachably plugged into the plug-in hole, and the pressure relief hole communicates with the inner cavity. When the air pressure in the inner cavity is less than a preset value, the sealing block seals the pressure relief hole with its own elasticity. When the air pressure in the inner cavity reaches the preset value, the air pressure in the inner cavity causes the sealing block to deform away from the pressure relief hole, thereby allowing the pressure relief hole to communicate with the outside and release pressure.

[0006] Optionally, the insertion part includes an insertion post and an outer flange disposed on the insertion post, the cup body includes a mounting plate, the insertion hole is disposed on the mounting plate, and a slot is provided between the sealing block and the outer flange to be detachably engaged with the mounting plate.

[0007] Optionally, the outer flange is arc-shaped.

[0008] Optionally, the plug post has a deformation cavity that facilitates the inward deformation of the outer flange.

[0009] Optionally, the deformation cavity is funnel-shaped.

[0010] Optionally, after the seal is removed, the sealing block recovers its elastic deformation and tilts toward one side of the insertion portion.

[0011] Optionally, the seal is provided with a handle, and external force is used to remove the seal from the cup body through the handle.

[0012] Optionally, the cup body includes a cup bottom, and the cup bottom is provided with a concave cavity for installing the seal.

[0013] Optionally, the pressure relief holes are connected to the insertion holes and there are several of them, and the several pressure relief holes are distributed in a ring with equal spacing.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] 1. Automatic pressure relief is achieved through the deformation of an elastic seal: When the internal air pressure reaches the preset value, the air pressure pushes the sealing block to deform away from the pressure relief hole to relieve pressure; when the air pressure is less than the preset value, the sealing block relies on its own elasticity to reset and seal the pressure relief hole; the structure is simple and the production cost is low.

[0016] 2. The sealing component is detachably connected to the insertion hole on the cup body through the insertion part, which allows the entire pressure relief mechanism to be quickly removed for thorough cleaning, effectively solving the hygiene hazards of dirt and grime accumulation and improving product safety and user experience;

[0017] 3. The groove formed between the outer flange and the sealing block allows for detachable snap-fit ​​fixing with the mounting plate; ensuring that the seal is stably fixed on the cup body under normal working conditions, maintaining reliable sealing; when cleaning is required, the user can easily remove the entire seal by pulling the groove away from the mounting plate, thus achieving both reliable sealing and convenient cleaning.

[0018] 4. The plug-in post has a deformation cavity that facilitates the inward deformation of the outer flange. When a disassembly force is applied, the outer flange can smoothly undergo sufficient elastic deformation into the deformation cavity, thereby easily disengaging from the mounting plate and making disassembly more convenient. Similarly, during installation, the outer flange can also smoothly undergo sufficient elastic deformation into the deformation cavity, thereby easily engaging with the mounting plate and making operation convenient.

[0019] 5. The deformation cavity is flared. During disassembly, the flared structure guides the outer flange to deform more smoothly and to a greater extent into the cavity, thereby greatly reducing the operating force required to separate the snap-fit ​​part from the mounting plate, making the disassembly process easier and smoother. In addition, when the air pressure in the inner cavity increases, the gas will fill the deformation cavity, and this gas pressure will act on the inclined inner wall of the flared mouth, pushing the inner wall of the flared mouth outward, thereby driving the outer flange outward. This can prevent the seal from being pulled away from the cup body due to excessive air pressure, increasing structural reliability.

[0020] In addition, this utility model also provides a stirring cup, including the aforementioned pressure relief structure that is easy to disassemble and clean. This stirring cup also has the same beneficial effect of the aforementioned pressure relief structure that is easy to disassemble and clean, which will not be described in detail here.

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0031] See Figures 1-6 This utility model provides a pressure relief structure that is easy to disassemble and clean, including a cup body 1 and an elastic sealing element 2. The sealing element 2 includes an integrally connected sealing block 21 and a plug-in part 22. The cup body 1 has an inner cavity 101, and the cup body 1 has a plug-in hole 11 and a pressure relief hole 12. The plug-in part 22 is detachably plugged into the plug-in hole 11, and the pressure relief hole 12 communicates with the inner cavity 101. When the air pressure in the inner cavity 101 is less than a preset value, the sealing block 21 seals the pressure relief hole 12 by its own elasticity. When the air pressure in the inner cavity 101 reaches the preset value, the air pressure in the inner cavity 101 causes the sealing block 21 to deform away from the pressure relief hole 12, so that the pressure relief hole 12 can be connected to the outside to relieve pressure.

[0032] Specifically, when the seal 2 is installed on the cup body 1, the sealing block 21 abuts against the cup body 1 and is subjected to the reaction force of the cup body 1, causing it to undergo elastic deformation. At this time, the sealing block 21 relies on its own elasticity to abut against the pressure relief hole 12, thereby sealing the pressure relief hole 12. This prevents food juices in the inner cavity 101 from leaking out of the cup body 1 when the air pressure in the inner cavity 101 is less than the preset value. The seal 2 is made of materials such as rubber or silicone. On the one hand, rubber or silicone itself has good sealing performance. This prevents liquid leakage; on the other hand, it gives the seal 2 good elasticity, so that the sealing block 21 can seal around the pressure relief hole 12 by its own elasticity; the preset value is the critical value at which the air pressure in the inner cavity 101 can cause the sealing block 21 to deform away from the pressure relief hole 12, which can be set by parameters such as the softness or thickness of the material of the sealing block 21. For example, the softer the material, the easier the sealing block 21 is to deform, and the smaller the preset value; the smaller the thickness, the easier the sealing block 21 is to deform, and the smaller the preset value.

[0033] This utility model features a pressure relief structure that is easy to disassemble and clean. It achieves automatic pressure relief through the deformation of the elastic sealing element 2: when the air pressure in the inner cavity 101 reaches a preset value, the air pressure pushes the sealing block 21 to deform away from the pressure relief hole 12 to relieve pressure; when the air pressure is less than the preset value, the sealing block 21 returns to its original position and seals the pressure relief hole 12 due to its own elasticity. The structure is simple and the production cost is low. At the same time, the sealing element 2 can be detachably connected to the insertion hole 11 on the cup body 1 through the insertion part 22, so that the entire pressure relief mechanism can be quickly disassembled for thorough cleaning, effectively solving the hygiene hazards of dirt and grime accumulation, and improving the safety of the product and the user experience.

[0034] See Figures 1-3The insertion part 22 includes an insertion post 221 and an outer flange 222 disposed on the insertion post 221. The cup body 1 includes a mounting plate 13, and an insertion hole 11 is disposed on the mounting plate 13. A groove 23 suitable for detachable engagement with the mounting plate 13 is provided between the sealing block 21 and the outer flange 222. Through the groove 23 formed between the outer flange 222 and the sealing block 21, a detachable engagement and fixation with the mounting plate 13 can be achieved. This ensures that under normal working conditions, the seal 2 is stably fixed on the cup body 1, maintaining reliable sealing. When cleaning is required, the user can easily remove the entire seal 2 by pulling out the groove 23 from the mounting plate 13, thus achieving reliable sealing and convenient cleaning.

[0035] See Figure 2 and Figure 3 The outer flange 222 is arc-shaped, which serves as a guide during disassembly and installation, allowing the seal 2 to be more smoothly engaged or disassembled with the mounting plate 13 of the cup body 1, thereby improving the feel of disassembly and installation and reducing component wear.

[0036] See Figure 3 The insertion post 221 has a deformation cavity 223 that facilitates the inward deformation of the outer flange 222. When a disassembly force is applied, the outer flange 222 can smoothly undergo sufficient elastic deformation into the deformation cavity 223, thereby easily disengaging from the mounting plate 13 and making disassembly more convenient. Similarly, during installation, the outer flange 222 can also smoothly undergo sufficient elastic deformation into the deformation cavity 223, thereby easily engaging with the mounting plate 13 and facilitating operation. The deformation cavity 223 is flared, and when disassembling, the flared opening... The opening structure guides the outer flange 222 to deform more smoothly and to a greater extent into the cavity, thereby greatly reducing the operating force required to separate the snap-fit ​​part from the mounting plate 13, making the disassembly process easier and smoother. In addition, when the air pressure in the inner cavity 101 increases, the gas will fill the deformation cavity 223, and this gas pressure will act on the inclined inner wall of the flared opening, pushing the inner wall of the flared opening outward, thereby driving the outer flange 222 outward. This can prevent the seal 2 from being pulled away from the cup body 1 due to excessive air pressure, increasing the structural reliability.

[0037] See Figure 3 , Figure 5 and Figure 6 After the seal 2 is removed, the sealing block 21 returns to its elastic deformation and tilts towards the side of the insertion part 22. When the seal 2 is installed on the cup body 1, the external force applies a reverse force to the tilted sealing block 21 so that it fits against the mounting plate 13. After installation, the sealing block 21 is forced to elastically deform from the tilted state to a relatively straight state. It relies on the elastic force generated by the deformation to abut against the mounting plate 13, thereby sealing the pressure relief hole 12. This realizes the function of sealing the sealing block 21 as soon as it is installed, making it convenient to use.

[0038] See Figures 1-3 The seal 2 is provided with a handle 201, and external force is used to remove the seal 2 from the cup body 1 through the handle 201; this allows the user to easily and effortlessly pull the seal 2 out of the insertion hole 11 with just their fingers without the need for tools, simplifying the disassembly steps and making daily cleaning and maintenance simple and quick.

[0039] See Figures 1-3 The cup body 1 includes a cup bottom 103, which has a concave cavity 102 for installing the seal 2. This allows the seal 2 to be installed in the concave cavity 102 in a concealed manner, ensuring the flatness of the cup bottom 103 and enabling the cup bottom 103 to be placed stably on the table. On the other hand, the concealed installation of the seal 2 in the concave cavity 102 reduces the possibility of accidental damage or detachment due to bumps during daily use, thus enhancing the reliability of the structure.

[0040] See Figures 2-4 The pressure relief holes 12 are connected to the insertion holes 11 and are provided in a plurality of them. The plurality of pressure relief holes 12 are distributed in a ring with equal spacing. The ring-shaped and equidistant arrangement of the pressure relief holes 12 enables the internal high-pressure airflow to be uniformly and quickly guided to the entire area covered by the sealing block 21, avoiding local airflow impact and uneven pressure release that may be caused by single-point pressure relief. In this embodiment, four pressure relief holes 12 are provided. Even if one pressure relief hole 12 is temporarily blocked, the other pressure relief holes 12 can still ensure the normal operation of the pressure relief function, thereby enhancing the safety and reliability of the product.

[0041] The implementation principle of the pressure relief structure that is easy to disassemble and clean according to the embodiment of this application is as follows: automatic pressure relief is achieved by the deformation of the elastic sealing element 2: when the air pressure in the inner cavity 101 reaches a preset value, the air pressure pushes the sealing block 21 to deform away from the pressure relief hole 12 to relieve pressure; when the air pressure is less than the preset value, the sealing block 21 relies on its own elasticity to reset and seal the pressure relief hole 12; the structure is simple and the production cost is low; the sealing element 2 is detachably connected to the insertion hole 11 on the cup body 1 through the insertion part 22, so that the entire pressure relief mechanism can be quickly disassembled for thorough cleaning. This effectively solves the hygiene hazards of dirt and grime accumulation, and improves product safety and user experience. The groove 23 formed between the outer flange 222 and the sealing block 21 can be detachably snapped and fixed with the mounting plate 13. This ensures that the seal 2 is stably fixed on the cup body 1 under normal working conditions, maintaining reliable sealing. When cleaning is required, the user can easily remove the entire seal 2 by pulling the groove 23 away from the mounting plate 13, thus achieving reliable sealing and convenient cleaning.
