Description

Technical Field

[0001] The present invention relates to the technical field of heat-insulated cups, and more specifically, it relates to a multifunctional stainless steel heat-insulated cup. Background Art

[0002] Heat-insulated cups are an essential part of people's lives. With them, drinking water will become more convenient.

[0003] In the prior art, there have also been some technical solutions regarding heat-insulated cups. For example, a Chinese patent with the application number 2015109752785 discloses a heat-insulated cup, which includes a cup body. The cup body is composed of an inner liner and an outer liner. The inner liner is provided with a collar. The outer liner is connected to the inner liner through the collar. A sandwich layer is provided between the inner liner and the outer liner. A liquid is provided in the sandwich layer. The liquid is a suspension crystal, a dispersant, and a nucleating agent. The inner liner is provided with a sealing ring. The sealing ring is located at the connection between the collar and the inner liner and the outer liner. The outer liner is connected to the collar by a thread. A water level scale is provided inside the inner liner. An anti-scalding protective sleeve is provided outside the outer liner. The anti-scalding protective sleeve is a plastic sleeve or a leather sleeve. A temperature-sensitive strip is provided on the anti-scalding protective sleeve. The temperature-sensitive strip can display different colors according to the temperature of the water. The suspension crystal is potassium nitrate or sucrose.

[0004] Currently, in the prior art, the inner liner and the cup body of a heat-insulated cup are generally in an integrated state. When the inner liner of the heat-insulated cup is contaminated or the outer shell of the cup body is damaged, people often directly discard the entire heat-insulated cup, resulting in a waste in the use of the heat-insulated cup.

[0005] Therefore, a solution needs to be proposed to solve this problem. Summary of the Invention

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a multifunctional stainless steel heat-insulated cup, which realizes the detachable connection between the inner liner and the outer shell through a connecting piece and a base, and can replace the inner liner or the outer shell separately, avoiding waste.

[0007] The above technical purpose of the present invention is achieved through the following technical solutions: A multifunctional stainless steel heat-insulated cup includes an outer shell and an inner liner. An installation block is fixedly connected to the bottom wall of the inner liner. An extension section is fixedly connected to the side of the installation block away from the inner liner. A through hole for the extension section to extend out is provided on the bottom wall of the outer shell. A base is provided on the lower end surface of the outer shell. A connecting piece is provided between the base and the extension section. The base and the extension section are detachably connected through the connecting piece.

[0008] By adopting the above technical solution, when the heat preservation cup is in normal use, the inner container is installed inside the outer shell. At this time, the installation block at the bottom of the inner container will be inserted into the through hole, and the extension section on the installation block will extend out of the through hole. Then, the base is detachably connected to the extension section from below through a connecting member. In this way, the base will abut against the bottom wall of the outer shell, preventing the extension section and the installation block from retracting into the outer shell through the through hole, and the inner container can be connected to the outer shell. When it is necessary to separate and replace the two, separating the base from the extension section allows the inner container to be taken out of the outer shell for individual replacement of the inner container or the outer shell, saving resources.

[0009] The present invention is further configured as: the connecting member includes a threaded hole provided on one side of the base close to the extension section, an external thread is provided on the outer wall of the extension section, and the extension section and the threaded hole are threadedly engaged through the external thread.

[0010] By adopting the above technical solution, after the extension section passes through the through hole and extends to the outside, the base rotates to screw the extension section into the threaded hole. After the base is tightened, it can be stably connected to the extension section, enabling the inner container to be installed in the outer shell. When it is necessary to separate the base from the extension section, hold the base and rotate it in the opposite direction to turn the base away from the extension section.

[0011] The present invention is further configured as: the connecting member includes a slot provided on the base, a knob rotatably connected to the outer wall of the base is sleeved on the outer wall of the base, a driving rod fixedly connected to one end thereof is provided on the inner wall of the knob, a fan-shaped groove for the driving rod to extend and rotate is provided on the inner wall of the slot, a clamping block is fixedly connected to the end of the driving rod extending into the slot, an access slot for the clamping block to insert is provided on the outer wall of the extension section, and a clamping groove for the clamping block to turn into is provided on the outer wall of the extension section, and the clamping groove is communicated with the access slot.

[0012] By adopting the above technical solution, when it is necessary to connect the extension section to the base, hold the knob and rotate it. After the knob rotates, it will drive the clamping block to rotate and move through the driving rod until the clamping block rotates to a position corresponding to the access slot. Then, the clamping block can be inserted along the access slot, and the base can be buckled on the bottom of the outer shell. Then, drive the clamping block to rotate again through the knob to make the clamping block turn into the clamping groove, and the base can no longer be pulled outwards, and it can be connected to the extension section. When it is necessary to separate the two, rotate the clamping block to a position where the access slot corresponds to the clamping groove, and then pull the clamping block out along the access slot.

[0013] The present invention is further configured as: a plurality of recessed sections are arranged in an array on the outer wall of the knob.

[0014] By adopting the above technical solution, a number of recessed segments distributed in an array are arranged to form anti-slip patterns, which increases the friction between the fingers and the knob and reduces the occurrence of slipping when rotating the knob.

[0015] The present invention is further configured such that: one end of the extension segment away from the mounting block is fixedly connected with a first magnetic attraction member, and a second magnetic attraction member that adsorbs with the first magnetic attraction member is fixedly connected to the bottom wall of the slot.

[0016] By adopting the above technical solution, when the extension segment is inserted into the slot, the first magnetic attraction member and the second magnetic attraction member will adsorb together, making the connection between the extension segment and the base more stable.

[0017] The present invention is further configured such that: the outer housing includes an outer layer housing and an inner layer housing, the inner container is in conformity with the shape of the inner layer housing, and a vacuum layer is formed between the outer layer housing and the inner layer housing.

[0018] By adopting the above technical solution, the vacuum layer can make the heat preservation effect of the outer housing better.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The present invention realizes the detachable connection of the inner container and the outer housing through the connecting member and the base, can replace the inner container or the outer housing separately, avoids waste, and can use the inner container as a container alone, so as to realize the switching between the heat preservation state and the ordinary container state, with more diverse functions and meeting the use requirements in more situations.

[0027] The present invention will be described in detail below with reference to the drawings.

[0028] Embodiment 1: A multi-functional stainless steel thermos cup, as Figure 1 shown, includes an outer shell 1 and an inner liner 2. The outer shell 1 includes an outer layer shell 17 and an inner layer shell 18. The inner liner 2 fits the shape of the inner layer shell 18, and a vacuum layer 8 is formed between the outer layer shell 17 and the inner layer shell 18.

[0029] An installation block 3 is fixedly connected to the bottom wall of the inner liner 2. An extension section 4 is fixedly connected to the side of the installation block 3 away from the inner liner 2. A through hole for the extension section 4 to extend out is provided on the bottom wall of the outer shell 1. A base 5 is provided on the lower end face of the outer shell 1. A connecting member is provided between the base 5 and the extension section 4, and the base 5 and the extension section 4 are detachably connected through the connecting member.

[0030] The connecting member includes a threaded hole 6 provided on the side of the base 5 close to the extension section 4. An external thread 7 is provided on the outer wall of the extension section 4, and the extension section 4 and the threaded hole 6 are threadedly engaged and connected through the external thread 7.

[0031] In the normal use of the thermos cup, the inner liner 2 will be installed inside the outer shell 1. At this time, the installation block 3 at the bottom of the inner liner 2 will be inserted into the through hole, and the extension section 4 on the installation block 3 will extend out of the through hole. Then, the base 5 is detachably connected to the extension section 4 from below through the connecting member. In this way, the base 5 will abut against the bottom wall of the outer shell 1, making it impossible for the extension section 4 and the installation block 3 to retract into the outer shell 1 through the through hole, and the inner liner 2 can be connected to the outer shell 1. When it is necessary to separate and replace the two, separating the base 5 from the extension section 4 can take out the inner liner 2 from the outer shell 1 for separate replacement of the inner liner 2 or the outer shell 1, saving resources.

[0032] After the extension section 4 extends out through the through hole to the outside, the base 5 rotates to turn the extension section 4 into the threaded hole 6. After the base 5 is tightened, it can be stably connected to the extension section 4, enabling the inner tank 2 to be installed in the outer shell 1. When it is necessary to separate the base 5 from the extension section 4, hold the base 5 and rotate it in the opposite direction to turn the base 5 away from the extension section 4. The structure is simple and the operation is convenient.

[0033] Embodiment 2: Compared with Embodiment 1, the difference in Embodiment 2 is that the structure of the connecting piece is different. As Figure 2 shown, in Embodiment 2, the connecting piece includes a slot provided on the base 5. A knob 9 rotatably connected to the outer wall of the base 5 is sleeved on the outer wall of the base 5. A driving rod 10 fixedly connected to one end of the inner wall of the knob 9 is provided on the inner wall of the knob 9. A fan-shaped groove 11 for the driving rod 10 to extend out and rotate is provided on the inner wall of the slot. A clamping block 12 is fixedly connected to the end of the driving rod 10 extending into the slot. An access slot 13 for the clamping block 12 to be inserted into is provided on the outer wall of the extension section 4. A clamping groove 14 for the clamping block 12 to be turned into is provided on the outer wall of the extension section 4. The clamping groove 14 communicates with the access slot 13.

[0034] A number of recessed sections are arranged in an array on the outer wall of the knob 9. The number of recessed sections arranged in an array form an anti-slip pattern, increasing the friction between the fingers and the knob 9 and reducing the occurrence of slipping when rotating the knob 9.

[0035] A magnetic part one 15 is fixedly connected to the end of the extension section 4 away from the mounting block 3. A magnetic part two 16 that adsorbs with the magnetic part one 15 is fixedly connected to the bottom wall of the slot. When the extension section 4 is inserted into the slot, the magnetic part one 15 and the magnetic part two 16 will adsorb together, making the connection between the extension section 4 and the base 5 more stable.

[0036] When it is necessary to connect the extension section 4 and the base 5 together, hold the knob 9 and rotate it. After the knob 9 rotates, it will drive the clamping block 12 to rotate and move through the driving rod 10 until the clamping block 12 rotates to a position corresponding to the access slot 13. Then the clamping block 12 can be inserted along the access slot 13, and the base 5 can be buckled on the bottom of the outer shell 1. Then, drive the clamping block 12 to rotate again through the knob 9 to turn the clamping block 12 into the clamping groove 14, and the base 5 can no longer be pulled outwards, and it can be connected to the extension section 4. When it is necessary to separate the two, rotate the clamping block 12 to a position where the access slot 13 corresponds to the clamping groove 14, and then pull the clamping block 12 out along the access slot 13.

[0037] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention.
