Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and in particular to an ornamental fish feeder, its manufacturing method, and its usage method. Background Technology

[0002] Feeding ornamental fish has become a major problem for many fish enthusiasts. Many ornamental fish require precise feeding, and overfeeding can severely shorten their lifespan. Furthermore, existing fish feeders cannot provide precise feeding, cannot preserve food for long periods, and are prone to mold and spoilage.

[0003] Even if there are fish feeders that can meet users' requirements, their structures are relatively complex and their prices are relatively high. For example, the components in related technology 201110108517.9 are not only numerous but also structurally complex. Therefore, the manufacturing process requires an overall sliding structure, and the product and mold structures are very complex. The large number of parts means that the installation requires a lot of manpower and resources, ultimately resulting in high costs.

[0004] For many enthusiasts, keeping fish is simply a hobby, requiring neither much nor much expense. Therefore, they need some low-cost and practical tools to help them with daily feeding, ensuring a fixed amount of food that can be stored for a long time, so that the ornamental fish can grow healthily. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an ornamental fish feeder that can achieve quantitative feeding and can be resealed after opening, thus allowing for long-term storage and preventing the feed from easily becoming moldy and spoiled.

[0006] This invention also proposes a method for manufacturing the above-mentioned ornamental fish feeder. This structure has few components, a simple production process, and can be produced on a fully automated production line, improving production efficiency while keeping manufacturing costs very low.

[0007] The present invention also proposes a method for using the above-mentioned ornamental fish feeder, which is easy to operate, can feed a fixed amount each time, and can be sealed and stored again after use.

[0008] An ornamental fish feeder according to a first aspect of the present invention includes:

[0009] The bottle body has a bottle mouth;

[0010] A feeding cap is provided on the bottle mouth. A receiving cavity is formed in the feeding cap. The receiving cavity is provided with a feeding port that communicates with the bottle body. A discharging port is provided on the other side of the receiving cavity opposite to the feeding port. A plurality of feedback parts are arranged in sequence inside the receiving cavity.

[0011] A spring-loaded switch is disposed on the feed cover and located between the feed inlet and the discharge outlet. The spring-loaded switch includes a pressing end, a metering chamber, a spring-loaded component, a sealing component, and a rebound component.

[0012] The metering chamber is movably located within the receiving cavity and has a first station connected to the feed inlet and a second station connected to the discharge outlet. The metering chamber is adapted to store a preset amount of feed at the first station.

[0013] The sealing element is adapted to move synchronously with the metering chamber, and is adapted to seal the discharge port when the metering chamber is in the first working position, and to leave the discharge port synchronously when the metering chamber leaves the first working position;

[0014] When the pressing end is pressed, it is adapted to drive the metering chamber to move, so that the metering chamber gradually switches from the first station to the second station;

[0015] The spring-loaded component is disposed between the feed cover and the pressing end, and the spring-loaded component is used to make the metering chamber tend to switch to the first station;

[0016] The spring-loaded fastener is adapted to move synchronously with the metering chamber. Based on the movement of the metering chamber, the spring-loaded fastener sequentially acts on each of the feedback units to determine the connectivity between the metering chamber and the discharge port based on the number of times the spring-loaded fastener triggers the feedback units.

[0017] The ornamental fish feeder according to the first aspect of the present invention has at least the following beneficial effects: quantitative feeding is achieved through the ingenious structural design of the feed cover and the spring-loaded switch, and the feeder can be resealed and stored after each quantitative feeding. The present invention has few overall structural components, simple manufacturing process, and can be produced through a fully automated production line.

[0018] According to a first aspect of the present invention, the ornamental fish feeder has a feeding cover made of an elastic material, and a portion of the spring-loaded switch is embedded in the receiving cavity so that the sealing element can fit tightly against the feeding port based on the elastic force.

[0019] According to a first aspect embodiment of the ornamental fish feeder, the sealing element is configured as a sealing boss, the cross-section of which is at least 1 mm larger than the cross-section of the discharge port.

[0020] According to the first aspect of the present invention, in the ornamental fish feeder, the sealing boss has a guide surface at one end face that is relatively far from the metering chamber;

[0021] And / or the pressing end has a non-slip surface.

[0022] According to a first aspect embodiment of the ornamental fish feeder, the spring-loaded switch further includes a bracket for connecting the metering chamber and the sealing element into a whole, and the bracket is adapted to be tightly abutting against the inner wall of the receiving cavity. The pressing end is disposed at one end of the bracket, and the spring-loaded element and the rebound element are respectively disposed on both sides of the bracket and extend protruding along the other end of the bracket.

[0023] According to a first aspect embodiment of the present invention, the ornamental fish feeder has a bottle body configured as a cylindrical structure, and a threaded structure is provided between the feed cover and the bottle mouth, wherein the feed cover and the bottle mouth are detachably connected by the threaded structure.

[0024] Alternatively, the bottle body may be configured as a rectangular structure, and a snap-fit ​​structure may be provided between the feeding cap and the bottle mouth, allowing the feeding cap and the bottle mouth to be detachably connected via the snap-fit ​​structure.

[0025] According to a first aspect embodiment of the ornamental fish feeder, a sealing film for sealing is provided between the feed cover and the bottle body.

[0026] According to a first aspect embodiment of the present invention, the fish feeder has a plurality of sequentially arranged feedback units configured as a plurality of sequentially arranged vertical bones, and the spring-loaded fastener is adapted to emit audible feedback when each of the vertical bones is touched.

[0027] A method for manufacturing an ornamental fish feeder according to a second aspect embodiment of the present invention includes the following steps:

[0028] The material discharge cover and the spring-loaded switch are injection molded using a mold. When molding the spring-loaded switch, the size of the mold core of the metering chamber is adjusted to control the capacity of the molded metering chamber.

[0029] The spring-loaded switch and the material discharge cover are assembled into a component cover;

[0030] The bottle is manufactured by sequentially filling, sealing, screwing on the cap, and sealing the opening.

[0031] A method of using an ornamental fish feeder according to a third aspect embodiment of the present invention includes the following steps:

[0032] When feeding is needed, press the pressing end to move the spring-loaded switch forward. The sealing element opens the discharge port, and the spring-loaded element gradually provides feedback as the spring-loaded switch moves. At the same time as the feedback is received, the metering chamber begins to discharge.

[0033] When feeding is stopped, the pressing end is released, the spring-loaded component begins to spring back, resetting the snap switch, and the sealing component re-seals the discharge port.

[0034] It is easy to understand that the method for manufacturing the ornamental fish feeder described in the second aspect embodiment of the present invention and the method for using the ornamental fish feeder described in the third aspect embodiment of the present invention both have the same technical effects as the ornamental fish feeder in the first aspect embodiment, and therefore will not be described again.

[0035] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0061] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention after considering the specific content of the technical solution.

[0062] Reference Figures 1 to 16 The ornamental fish feeder of the first aspect of the present invention includes a bottle body 100, a feeding cap 200, and a spring-loaded switch 300.

[0063] The bottle body 100 has a bottle mouth 110; a feeding cap 200 is disposed on the bottle mouth 110, and a receiving cavity 210 is formed in the feeding cap 200. The receiving cavity 210 is provided with a feeding port 211 communicating with the bottle body 100. A discharging port 212 is provided on the other side of the receiving cavity 210 opposite to the feeding port 211. The receiving cavity 210 is provided with a plurality of feedback parts 220 arranged in sequence inside; a spring-loaded switch 300 is disposed on the feeding cap 200 and located between the feeding port 211 and the discharging port 212. The spring-loaded switch 300 includes a pressing end 310, a metering chamber 320, a spring-loaded component 330, a sealing component 340, and a rebound component 350. The metering chamber 320 is movably located within the receiving cavity 210 and has a first station for docking with the feed inlet 211 and a second station for docking with the discharge outlet 212. The metering chamber 320 is adapted to store a preset amount of feed at the first station. The sealing element 340 is adapted to move synchronously with the metering chamber 320. The sealing element 340 is adapted to seal the discharge outlet 212 when the metering chamber 320 is in the first station and to simultaneously leave the discharge outlet 212 when the metering chamber 320 leaves the first station. The pressing end 310 is adapted to drive the metering chamber when it is pressed. The metering chamber 320 is activated to gradually switch from the first station to the second station; the spring-loaded part 350 is disposed between the discharge cover 200 and the pressing end 310, and the spring-loaded part 350 is used to make the metering chamber 320 tend to switch to the first station; the spring-loaded fastener 330 is adapted to move synchronously with the metering chamber 320, and the spring-loaded fastener 330 acts on each feedback part 220 in sequence based on the movement of the metering chamber 320, so as to determine the connection between the metering chamber 320 and the discharge port 212 according to the number of times the spring-loaded fastener 330 triggers the feedback part 220.

[0064] Understandably, the feeding amount of the metering chamber 320 can be set according to different needs, and the feeding amount can be used to maximize the feed inlet 211 and the discharge outlet 212. When setting, the size of the metering chamber 320 can be changed simply by modifying the size of the mold core, so as to achieve variable feeding.

[0065] In some embodiments, based on the sound feedback function, hearing the first sound when pressing the spring-loaded fastener 330 indicates that one-quarter of the material has been dispensed from the outlet 212, hearing the second sound indicates that one-half of the material has been dispensed from the outlet 212, and so on. Specifically, the outlet 212 is preferably rectangular, increasing the number of dispensing positions and enabling controllable discharge. For example, if the total volume of the metering chamber 320 is 30 ml, the outlet 212, in conjunction with the spring-loaded fastener 330, can dispense 10 ml / 20 ml / 30 ml at a time for targeted design.

[0066] In some embodiments, this ornamental fish feeder can be used for raising fish or other animals. By adjusting the size of the feed inlet 211 and the feed outlet 212 to match the feed for different animals, different animals can be fed in a fixed quantity. After use, it can be sealed and stored again for convenient daily feeding.

[0067] Reference Figures 1 to 16 The ornamental fish feeder of the first aspect of the present invention achieves quantitative feeding through the ingenious structural design of the feeding cover 200 and the spring-loaded switch 300, and can be resealed and stored after each quantitative feeding. The present invention has few structural components and a simple production process, and can be produced through a fully automated production line.

[0068] In some embodiments of the present invention, the feed cover 200 is made of an elastic material, and a portion of the spring-loaded switch 300 is embedded in the receiving cavity 210 so that the sealing member 340 can fit tightly against the discharge port 212 based on the elastic force. It is understood that the tight fit between the sealing member 340 and the discharge port 212 can achieve a secondary seal, effectively preventing the emission of feed odor and preventing the attraction of pests.

[0069] In some embodiments, the feeder is made of a highly elastic rubber material. After each use, the elasticity of the feeder compresses the sealing element 340, thus achieving a secondary seal to prevent air leakage and thus preventing the feed from easily becoming moldy and spoiled due to air leakage. In other embodiments, the feeder can also be made of other highly elastic materials, thereby utilizing the elasticity to ensure that the sealing element 340 fits tightly against the discharge port 212.

[0070] In some embodiments of the present invention, the seal 340 is configured as a sealing boss, the cross-section of which is at least 1 mm larger than the cross-section of the outlet 212. It is understood that a good sealing effect is ensured by specifically designing the structure of the seal 340. Furthermore, the size of the sealing boss is limited so that when the spring-loaded switch 300 is in the reset state, the sealing boss can reliably seal the outlet 212.

[0071] In some embodiments, the cross-section of the sealing boss is at least 1 mm larger than the cross-section of the outlet 212. This can be understood as the shortest side of the sealing boss's cross-section being at least 1 mm longer than the longest side of the outlet 212's cross-section, in order to ensure a good sealing effect.

[0072] In some embodiments of the present invention, a guide surface 341 is provided on the end face of the sealing boss that is relatively far from the metering chamber 320; it is understood that the provision of the guide surface 341 helps the sealing boss to be in place and away from the discharge port 212, making the sliding of the spring-loaded switch 300 smoother. Based on the elastic fit of the guide surface 341 of the feeder, the sealing element 340 can also be better fitted tightly to the discharge port 212.

[0073] In some embodiments of the present invention, the spring-loaded switch 300 further includes a bracket 360, which is used to connect the metering chamber 320 and the sealing element 340 into a whole. The bracket 360 is adapted to fit tightly against the inner wall of the receiving cavity 210. The pressing end 310 is disposed at one end of the bracket 360, and the spring-loaded element 330 and the return element 350 are respectively disposed on both sides of the bracket 360 and extend protruding along the other end of the bracket 360. It is understood that the spring-loaded switch 300 is generally injection molded or blow molded, so the bracket 360 can essentially connect the metering chamber 320, the sealing element 340, the pressing end 310, the spring-loaded element 330, and the return element 350 into a whole structure. In some embodiments, considering the elastic effect of the discharge cover 200, the height dimension of the bracket 360 needs to be adapted to the internal height dimension of the receiving cavity 210 of the discharge cover 200. Thus, while the bracket 360 slides within the receiving cavity 210, it is continuously subjected to the elastic force of the discharge cover 200, resulting in higher positioning accuracy of the seal 340.

[0074] In some embodiments of the present invention, specific references are made. Figures 9 to 16 The bottle body 100 is configured as a cylindrical structure, and a threaded structure is provided between the dispensing cap 200 and the bottle mouth 110. The dispensing cap 200 and the bottle mouth 110 are detachably connected by the threaded structure. It is understood that the threaded assembly of the bottle body 100 and the dispensing cap 200 facilitates easy use. In other embodiments of the present invention, please refer to... Figures 1 to 8The bottle body 100 is designed as a rectangular structure, and a snap-fit ​​structure is provided between the feeding cap 200 and the bottle mouth 110. The feeding cap 200 and the bottle mouth 110 are detachably connected by the snap-fit ​​structure.

[0075] In other embodiments, the connection between the discharge cap 200 and the bottle opening 110 can also be fixed by a detachable connection method such as nesting or snap-fit, thereby expanding the application scenarios. See specific reference... Figures 1 to 8 The shapes and structures of the discharge cap 200 and the bottle mouth 110 can be designed specifically, such as square, and fixed by detachable connection methods such as nesting and snap-fit. In other embodiments, they can also be set to elliptical or other shapes, and different connection methods can be selected to meet different needs.

[0076] In some embodiments of the present invention, the pressing end 310 has an anti-slip surface 311. It is understood that providing an anti-slip surface 311 on the spring-loaded switch 300 facilitates operation and control of the pushing force, thereby enabling more precise quantitative feeding.

[0077] In some embodiments, the anti-slip surface 311 may be composed of multiple vertical ribs arranged in sequence to form a contact surface with anti-slip function. The user presses the snap switch 300 by applying force to the anti-slip surface 311. In other embodiments, the anti-slip surface 311 may be a rough surface, and the corresponding anti-slip design can be achieved by changing the roughness of the surface.

[0078] In some embodiments of the present invention, a sealing film 400 is provided between the feed cap 200 and the bottle body 100 for sealing. It is understood that the sealing film 400 can prevent the feed from easily becoming moldy and deteriorating due to air leakage, which increases the shelf life of the feed inside by at least three times.

[0079] In some embodiments, the sealing film 400 can be directly punctured using a small tool to connect the bottle body 100 to the feed inlet 211. In other embodiments, considering that the feed cap 200 and the bottle opening 110 are detachably connected, the feed cap 200 can be unscrewed, and then the sealing film 400 can be torn off for normal use. Specifically, the sealing film 400 can be aluminum film or aluminum foil; using aluminum film to seal the bottle opening 110 effectively prevents the feed from becoming moldy and spoiled. In other embodiments, the sealing film 400 can be made of other materials with sealing properties.

[0080] It should be noted that, in this embodiment of the ornamental fish feeder, after the aluminum film is torn open, the threads of the bottle opening 110 and the feeder provide a pushing point, thereby pressing the connection between the bottle opening 110 and the feeder to achieve a seal. During normal closure, the sealing element 340, under the pushing force of the spring-loaded element 350, completes the sealing effect on the outlet 212; when feeding is started, external force pushes open the sealing element 340 to complete the feeding function; when released, the sealing element 340 returns to its original position under the action of elasticity. More specifically, during normal closure, the elastic compression effect of the feed cover 200 on the bracket 360 provides the pushing force to complete the sealing function of the outlet 212. When the feeding action is started, the end of the metering chamber 320 that connects to the feed inlet 211 is sealed by the discharge cover 200. Before the spring-loaded fastener 330 contacts the feedback unit 220, the end of the metering chamber 320 that connects to the discharge outlet 212 is also sealed by the discharge cover 200. When the spring-loaded fastener switch 300 is gradually pushed to trigger the feedback unit 220, the metering chamber 320 gradually connects to the discharge outlet 212 and feeding is realized.

[0081] In some embodiments of the present invention, a plurality of sequentially arranged feedback units 220 are configured as a plurality of sequentially arranged vertical ribs, and the spring-loaded fastener 330 is adapted to emit audible feedback when each vertical rib is touched. It is understood that the spring-loaded fastener 330 is elastic so that it can sequentially contact and disengage from each vertical rib when the spring-loaded switch 300 is active, and audible feedback is emitted each time it contacts or disengages, that is, the spring-loaded switch 300 produces a sound when pressed into place, and audible feedback is emitted again when it is released based on the reset of the return spring 250.

[0082] In some embodiments, the spring-loaded switch 300 moves horizontally, and each vertical rib is a vertically arranged protrusion. The combination of these two elements enables the fish feeder to have an audible feedback function. In other embodiments, the feedback unit 220 can be a protrusion, teeth, or similar element that mates with the spring-loaded switch 330. Specifically, the spring-loaded switch 330, based on its elasticity, provides feedback with a reaction force when the user presses the pressing end 310, allowing the user to clearly know the connection between the metering chamber 320 and the discharge port 212, thus knowing the flow rate of the discharge port 212 at each setting and accurately feeding the fish.

[0083] Reference Figures 1 to 16 The second aspect of the present invention provides a method for manufacturing an ornamental fish feeder, which can be the same as the method for manufacturing an ornamental fish feeder according to the first aspect of the present invention. The method for manufacturing an ornamental fish feeder includes the following steps:

[0084] The material discharge cover 200 and the spring-loaded switch 300 are injection molded by mold. When molding the spring-loaded switch 300, the size of the mold core of the metering chamber 320 is adjusted to control the capacity of the metering chamber 320.

[0085] The spring-loaded switch 300 and the feed cover 200 are assembled into a component cover;

[0086] The bottle 100 is made by sequentially filling, sealing, screwing on the cap, and sealing the opening.

[0087] In other embodiments, the bottle body 100 can be manufactured manually by sequentially performing the above-described processes. However, due to the simple structural design and few parts of the present invention, in some embodiments of the present invention, the above-described manufacturing method can be directly carried out on a fully automated production line, thereby greatly improving production efficiency.

[0088] In some embodiments, after assembling the spring-loaded switch 300 and the feeding cap 200 into a component cap, aluminum foil is attached to the component cap, and then the component cap is transferred to the cap storage cavity of the capping mechanism. When the bottle 100 is placed on the automated production line to complete the automatic weighing and filling of fish feed, it is transferred to the downstream capping mechanism to perform the capping process, and finally transferred to the automatic electromagnetic induction sealing machine to seal the bottle mouth 110, thereby realizing production on a fully automated production line. Moreover, when filling feed, the bottle mouth 110 faces upward, which can realize fully automated filling. Using an automatic capping machine for capping can greatly improve production efficiency. At least 60 bottles of feed can be produced and filled per minute. This device can repeatedly fill feed and be recycled, achieving the effects of environmental protection, energy saving, and carbon reduction, and reducing pollution to the earth's environment.

[0089] It is understood that after the molds for the bottle body 100, the feeding cap 200 and the spring-loaded switch 300 of the present invention are made, they are molded into product parts by injection molding or blow molding machines. In other embodiments, since the production of the bottle body 100 itself is not difficult, it can also be produced by other means, which will not be described in detail here.

[0090] Understandably, the materials used in this structure are environmentally friendly and lightweight, and the feeding amount can be set according to different needs. The size of the metering chamber 320 can be modified simply by changing the mold, so as to achieve variable feeding.

[0091] Reference Figures 1 to 16 The method of using the ornamental fish feeder according to the third aspect of the present invention can be the same as the method of using the ornamental fish feeder according to the first aspect of the present invention. The method of using the ornamental fish feeder includes the following steps:

[0092] When feeding is needed, press the pressing end 310 to move the spring-loaded switch 300 forward as a whole. The sealing element 340 opens the discharge port 212, and the spring-loaded element 330 gradually emits feedback as the spring-loaded switch 300 moves. At the same time as the feedback is emitted, the metering chamber 320 starts to discharge.

[0093] When feeding stops, release the pressing end 310, the spring-loaded part 350 begins to spring back, causing the spring-loaded switch 300 to reset, and the sealing part 340 re-seals the discharge port 212.

[0094] It is understood that the ornamental fish feeder of this embodiment of the invention uses a spring-loaded switch 300 to achieve quantitative feeding. Each time the switch is pressed, the amount of feed dispensed is at least a portion of the amount in the metering chamber 320. After releasing the switch, the feed will automatically spring back, thereby achieving quantitative feeding. The feed can be sealed in packaging and can be resealed after opening. It can be stored for a long time, with a shelf life of up to three years, and is not prone to mold or spoilage.

[0095] More specifically, in the specific method of use, the pressing end 310 at the front end of the spring-loaded switch 300 is pressed by hand. The pressing end 310 is provided with anti-slip vertical ribs, causing the spring-loaded switch 300 to move forward as a whole. The sealing boss opens the discharge port 212, and the metering chamber 320 begins to discharge material. The spring-loaded fastener 330 will make an audible sound to confirm each degree of advancement. When the hand is released, the spring-loaded switch 300 begins to rebound under the action of the spring force of the return spring 350, and the sealing boss resets.
