Description

Technical Field

[0001] The utility model relates to the technical field of vacuum bottles, and mainly relates to a single-layer middle-ring vacuum bottle. Background Art

[0002] A vacuum bottle refers to a container that can isolate gas from the external temperature or isolate external bacteria. Currently, the commonly used vacuum bottles on the market are composed of a container, a vacuum pump, and a piston installed at the bottom.

[0003] For example, a prior application with a publication number of CN220683353U by the applicant discloses a single-layer middle-ring vacuum bottle. The middle ring of the single-layer middle-ring vacuum bottle includes an inner ring and an outer ring, and the inner ring and the outer ring are of an integral structure. The middle ring is integrally formed by an injection molding process, which not only ensures the required strength but also saves the cost of injection molds, and also reduces an assembly process, reducing the input of manpower and material resources during the assembly of the vacuum bottle. However, the applicant also found the following problems during the actual implementation process: The single-layer middle-ring vacuum bottle only has a single annular clamping protrusion 20 and an annular clamping groove 22 that cooperates with the annular clamping protrusion 20. Since the middle ring is a single-layer structure, if there is only one clamping structure, the sealing performance between the bottle body and the middle ring will be poor, and the stability between the bottle body and the middle ring will also be poor. Summary of the Utility Model

[0004] The utility model aims to solve at least one problem existing in the prior art. For this purpose, the object of the utility model is to provide a single-layer middle-ring vacuum bottle, which adopts a multi-channel clamping structure to make the sealing performance and stability between the bottle body and the middle ring better.

[0005] To achieve the above object, the utility model provides:

[0006] A single-layer middle-ring vacuum bottle, comprising a bottle body, a middle section installed on the bottle body, a pump core installed on the middle section, a head cap installed on the pump core, and a piston installed inside the bottle body. The outer wall of the piston is closely attached to the inner wall of the bottle body. Multiple first snap ribs are provided on the inner wall of the bottle mouth of the bottle body, and a clamping groove is formed between two adjacent first snap ribs. Multiple second snap ribs are provided on the middle section, and the first snap ribs and the second snap ribs are in clamping cooperation.

[0007] Preferably, a plug is provided at the top of the bottle mouth of the bottle body, and the outer side surface of the plug is an inclined surface; a socket adapted to the plug is provided at the bottom of the middle section, and the inner side surface of the socket is also an inclined surface.

[0008] Preferably, a groove is provided at the top of the head cap.

[0009] Preferably, a discharge channel is provided inside the head cap, and the discharge channel is inclined upward.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Multiple buckles are provided on the bottle body and the middle section, and the clamping structure formed by the multiple buckles makes the sealing performance and stability between the bottle body and the middle ring better.

[0012] 2. The design of the groove at the top of the head cap can improve the pressing feeling of the user and is not easy to slip.

[0013] 3. The inclined discharge channel has the advantages of no dripping and no material hanging.

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are only examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0021] Please refer specifically to Figure 1-2 , a single-layer middle-ring vacuum bottle, comprising a bottle body 1, a middle section 2 mounted on the bottle body 1, a pump core 3 mounted on the middle section 2, a head cap 4 mounted on the pump core 3, and a piston 5 mounted inside the bottle body 1. The outer wall of the piston 5 is in close fit with the inner wall of the bottle body 1. Three first snap ribs 101 are provided on the inner wall of the bottle mouth of the bottle body 1, and two second snap ribs 201 are provided on the middle section 2. The first snap ribs 101 and the second snap ribs 201 are engaged with each other in a snap-fit manner. The snap-fit structure formed by multiple snap ribs makes the sealing performance and stability between the bottle body 1 and the middle ring better. Specifically, a slot is formed between two adjacent first snap ribs 101, and there are two slots in total. The two second snap ribs 201 are respectively snapped into the slots.

[0022] Further, a plug 102 is provided at the top of the bottle mouth of the bottle body 1, and a socket 202 adapted to the plug 102 is provided at the bottom of the middle section 2. The plug 102 can be inserted into the socket 202, and the bottle body 1 and the middle section 2 are fixed together under the snap-fit of the first snap ribs 101 and the second snap ribs 201.

[0023] Further, the outer side surface of the plug 102 is a bevel surface, and the inner side surface of the socket 202 is also a bevel surface. The two bevel surfaces fit together, enabling the plug 102 and the socket 202 to be closely fitted together, thereby increasing the sealing performance of the bottle body 1.

[0024] Further, a groove 401 is provided at the top of the head cap 4, which can improve the pressing feeling of the user and is not easy to slip.

[0025] Furthermore, a discharge channel 402 is provided inside the headgear 4. The discharge channel 402 slopes upward. The upward-sloping discharge channel 402 has the advantages of not dripping or hanging materials compared to a horizontal discharge channel 402.

[0026] The utility model adopts a middle ring with a single-layer structure. The middle ring is equivalent to the middle section 2 and the shoulder sleeve in a traditional vacuum pump. The middle section 2 and the shoulder sleeve are integrated together, reducing one component and one assembly process. The middle ring is made by a set of injection molds, saving the cost of injection molds and reducing the input of manpower and material resources during the assembly of the vacuum bottle.

[0027] Preferably, the bottle body 1 is made of a styrene-free environmentally friendly material.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the utility model.
