[0023] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0024] In the description of the utility model, it is necessary to explain that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.
[0026] The embodiment of the utility model discloses a connecting kit, and the following is combined with the drawings Figures 1-6 The technical scheme of the connecting kit is specifically described.
[0027] Specifically, the connecting kit in the embodiment shown in the figure includes upper shell 1 and lower shell 2, the upper shell 1 is used to be sleeved on the top of at least three gas cylinders 3, and the lower shell 2 is used to be sleeved on the bottom of at least three gas cylinders 3; the upper shell 1 is provided with a cylinder joint 4, the cylinder joint 4 has at least three cylinder interfaces 41, one of the cylinder interfaces 41 is connected with one gas cylinder 3, and the cylinder joint 4 is communicated with a connecting pipe 5 for being communicated with a warmer.
[0028] It can be known that, compared with the prior art, the connecting kit is equivalent to expansion, and at least three gas cylinders 3 can be installed simultaneously, and the purpose is to improve the heating duration and stability. For example, in cold weather, users may need to use the warmer for a long time to keep warm, and the gas capacity of a single gas cylinder 3 in the prior art is limited, which cannot meet the long-time heating demand. The embodiment can install at least three gas cylinders 3 simultaneously by expanding the connecting kit, greatly increasing the gas storage capacity, thereby meeting the long-time heating demand of users.
[0029] Since the existing connecting kit can only install one gas cylinder 3, the user needs to frequently replace the gas cylinder 3 during use to ensure the normal operation of the warmer, which not only increases the operation burden of the user, but also may cause some safety problems in the process of replacing the gas cylinder 3. The embodiment can install at least three gas cylinders 3 simultaneously by expanding the connecting kit, which can greatly reduce the frequency of replacing the gas cylinder 3 of the user and the operation times of the user, so as to reduce the trouble of frequently replacing the gas cylinder 3, and the user can use the warmer more conveniently.
[0030] Specifically, each of the bottle interfaces 41 has an interface valve core inside. The purpose of the arrangement is that the interface valve core plays a key sealing role at the bottle interface 41, can play a reverse stop role when the gas cylinder 3 is not installed, and can effectively prevent the gas in the gas cylinder 3 from leaking to the external environment from the bottle interface 41, which provides an important guarantee for the safe use of the heater and greatly reduces the safety risk caused by gas leakage.
[0031] Specifically, the end of the connecting pipe 5 that communicates with the heater has a pipe valve core. The purpose of the arrangement is that the pipe valve core plays a key sealing role at the end of the connecting pipe 5, can play a reverse stop role when the connecting pipe 5 is not installed on the heater, and can effectively prevent the gas in the gas cylinder 3 from leaking to the external environment from the connecting pipe 5, which greatly reduces the probability of safety accidents caused by gas leakage and provides a more reliable safety guarantee for users using the gas heater.
[0032] Specifically, the upper shell 1 has an assembly hole 11, and the connecting pipe 5 extends out of the upper shell 1 through the assembly hole 11. The purpose of the arrangement is that since the connecting pipe 5 is responsible for transporting the gas in the gas cylinder 3 to the inside of the heater for combustion, by providing the assembly hole 11 on the upper shell 1 of the heater and allowing the connecting pipe 5 to extend out of the upper shell 1 through the hole, a relatively direct and smooth gas transportation path can be provided for the connecting pipe 5. Compared with other possible more tortuous or complex layout methods, this design can reduce the friction and collision of the gas with the inner wall of the pipe during transportation, reduce the resistance of the gas flow, and thus ensure that the gas can be transported from the gas cylinder 3 to the inside of the heater with high efficiency, providing reliable gas supply guarantee for the stable operation and efficient heating of the heater.
[0033] Moreover, the assembly of the upper shell 1 and the connecting pipe 5 is an important link in the production and manufacturing process of the heater. By providing the assembly hole 11 on the upper shell 1 of the heater, the connecting pipe 5 can be directly installed through the hole, which greatly simplifies the assembly process between the connecting pipe 5 and the upper shell 1. Compared with other design methods that may require complex connection structures or multiple installation steps, this installation method of directly passing through the assembly hole 11 is more intuitive and convenient, which can reduce the operation difficulty and time consumption in the assembly process, improve the production efficiency, and reduce the production cost.
[0034] Further, the outer side of the upper shell 1 is provided with a clamping member 12 for clamping the connecting pipe 5 when the connecting pipe 5 is wound around the upper shell 1. The purpose of the clamping member 12 is to orderly place the connecting pipe 5 along a specific track when the connecting kit is not in use, so as to avoid contact with sharp objects and reduce damage or deformation of the connecting pipe 5 caused by accidental collision or friction, thereby prolonging the service life of the connecting pipe 5. Moreover, winding the connecting pipe 5 around the outer side of the upper shell 1 can form a relatively compact whole. Compared with randomly placing the connecting pipe 5, this way can greatly reduce the occupied space and facilitate placing the connecting pipe 5 in a cabinet, corner or other storage space, thereby improving the space utilization efficiency.
[0035] Further, the clamping member 12 includes a pair of clamping pieces 121 arranged in an upper-lower interval, and a gap 122 is formed between the two clamping pieces 121 for clamping the connecting pipe 5. The purpose of the clamping member 12 is that the pair of clamping pieces 121 are arranged in an upper-lower interval, and when the connecting pipe 5 is clamped in the gap 122 between the two clamping pieces 121, the upper and lower clamping pieces 121 can constrain the connecting pipe 5 from the vertical direction to prevent the connecting pipe 5 from shifting or shaking in the vertical direction. At the same time, the size of the gap 122 between the two clamping pieces 121 is matched with the outer diameter of the connecting pipe 5, so that the clamping pieces 121 can tightly clamp the connecting pipe 5 in the horizontal direction to limit the movement of the connecting pipe 5 in the horizontal direction. Through such multidirectional constraint, the connecting pipe 5 can be kept in a stable position in the clamping member 12, and even under the action of a certain external force, the connecting pipe 5 is not easy to shift or fall off, so as to better store the connecting pipe 5.
[0036] Further, the connecting kit has a storage state in which the upper shell 1 and the lower shell 2 are assembled together. The purpose of the clamping member 12 is that the upper shell 1 and the lower shell 2 are assembled together to form a regular whole, which greatly reduces the occupied area in the storage space compared with placing the components separately. Whether placed in a cabinet, a warehouse or carried out, the space can be more effectively utilized, and the connecting kit is convenient to store and transport. Moreover, the complete assembly of the upper and lower shells 2 makes the connecting kit more convenient to carry, and the components are not easy to scatter and lose. For example, when moving or carrying out, the integrated kit is easier to take and carry, thereby improving the portability of the product.
[0037] Further, in the storage state, the upper shell 1 and the lower shell 2 are assembled with interference. The purpose of this design is that the interference assembly means that there is a certain pressure and friction between the upper shell 1 and the lower shell 2. This tight connection can effectively prevent the upper shell 1 and the lower shell 2 from being separated due to external forces (such as collision, vibration, etc.) during storage, transportation or other daily operations, thereby ensuring the safety of the internal components of the connection kit. Moreover, after the interference assembly of the upper shell 1 and the lower shell 2, they can form a more stable overall structure. This structure can better withstand external pressure and impact, improving the overall structural strength of the connection kit.
[0038] Further, the lower shell 2 is hollowed out at the position corresponding to the bottom of the gas cylinder 3, so that the bottom of the gas cylinder 3 is embedded in the hollow area 21 and is clamped with the hollow area 21. The purpose of this design is that the lower shell 2 is hollowed out at the position corresponding to the bottom of the gas cylinder 3, providing a window for the user to directly observe the state of the bottom of the gas cylinder 3. Through this window, the user can conveniently observe whether there is any abnormal condition such as corrosion, wear, deformation, etc. at the bottom of the gas cylinder 3. For example, during long-term use, the bottom of the gas cylinder 3 may be corroded due to contact with the ground, moisture, etc. If the lower shell 2 is not hollowed out, it is difficult for the user to discover the corrosion of the bottom of the gas cylinder 3 in time, which may lead to leakage or even explosion of the gas cylinder 3 during use. Through the hollow design of the lower shell 2, the user can regularly observe the state of the bottom of the gas cylinder 3, discover and handle potential safety hazards in time, and ensure the safe use of the gas cylinder 3.
[0039] Moreover, the hollow design reduces the amount of material used for the lower shell 2. Since the lower shell 2 does not need complete plate material at the position corresponding to the bottom of the gas cylinder 3, through reasonable hollowing, the material of this part can be saved, directly reducing the cost of raw materials. Especially in mass production, the saved material of each connection kit adds up, which can bring significant cost advantage to the enterprise. Moreover, the hollow part of the lower shell 2 reduces its own weight, making the entire warmer connection kit more portable. For users who need to move the warmer frequently, the reduced weight makes the transportation process easier and reduces the labor intensity.
[0040] More importantly, the bottoms of the three gas cylinders 3 are correspondingly clamped into the three hollow areas 21, so that the three gas cylinders 3 and the lower shell 2 form a relatively fixed and stable structure, improving the stability of the overall structure.
[0041] Specifically, the hollowed-out area 21 is circular, and the circumferential edge of the hollowed-out area 21 extends outward by at least three extended hollowed-out portions 22. The purpose of the arrangement is that the circular hollowed-out area 21 is relatively easy to realize in mold design and manufacturing compared with other shapes, and the number and shape of the extended hollowed-out portions 22 can be flexibly adjusted according to the process requirements of mold manufacturing. In this way, the manufacturing difficulty and cost of the mold can be reduced, and the production efficiency and service life of the mold can be improved, thereby reducing the manufacturing cost of the entire warmer connecting kit. Moreover, in the production process, the circular hollowed-out area 21 and the simple extended hollowed-out portion 22 structure facilitate the use of automatic processing equipment for processing, such as laser cutting, stamping, etc. These processing methods can improve the production efficiency, ensure the consistency of product quality, and at the same time, reduce the errors and costs caused by manual operation.
[0042] The technical means disclosed in the utility model scheme is not only limited to the technical means disclosed in the above-mentioned embodiments, but also includes the technical scheme composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
