Description

Technical Field

[0001] This utility model relates to a lamp, and more particularly to a fish tank lamp with a feeding function. Background Technology

[0002] With the continuous improvement of people's living standards, ornamental fish farming has become an important form of leisure and entertainment. Fish tanks not only provide a habitat for ornamental fish but also serve as an important decorative element in homes and offices. In the daily maintenance of fish tanks, lighting and feeding are two of the most basic and crucial functional requirements. Appropriate lighting not only promotes photosynthesis in aquatic plants and maintains the ecological balance of the aquarium but also enhances the viewing experience. Meanwhile, regular and measured feeding directly affects the healthy growth and survival of the fish, and is a key factor in maintaining a healthy ecological environment in the aquarium.

[0003] Currently, most aquarium equipment on the market is single-function. Lighting devices typically use independent LED lamps or fluorescent tubes, fixed above the aquarium via brackets or suspenders, providing basic illumination. Existing aquarium lighting products are relatively mature in technology, featuring adjustable light intensity, variable color temperature, and timer control, meeting the lighting needs of different aquatic organisms. Meanwhile, various types of automatic feeders are also available, using motors and timer controls to automatically dispense fish food, solving the problem of timely feeding when fish keepers are away for extended periods or busy with work. These devices perform well in their respective functional areas, providing convenience for ornamental fish keeping.

[0004] However, in existing aquarium technology, lighting and feeding devices are typically two independent systems that require separate installation and control. This separate design has significant drawbacks. Two independent devices need to be installed above the aquarium, not only occupying limited overhead space but also negatively impacting the overall visual appeal due to inconsistent structures and appearances. Furthermore, separate installation requires users to understand the installation requirements and fixing methods for different devices, increasing complexity and technical barriers, making operation somewhat difficult. In addition, each independent device requires separate cleaning, inspection, and component replacement for routine maintenance, making maintenance tedious and prone to oversight, increasing the user's burden.

[0005] Therefore, there is an urgent need for a multifunctional aquarium device that integrates lighting and feeding functions to achieve integrated equipment, improve space utilization efficiency, simplify user operation, and reduce overall costs. Summary of the Invention

[0006] The purpose of this utility model is to provide a fish tank light with a feeding function, which integrates lighting and feeding functions into one unit, reduces the space occupied by the equipment, and improves the convenience of installation and overall aesthetics.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fish tank light with a feeding function, including a light panel, and further comprising, The mounting cylinder has one end connected to the lamp panel; The feed cylinder is rotatably connected to the mounting cylinder or the light plate, and the feed cylinder is provided with a storage cavity for holding fish food; A transmission mechanism, connected to the material cylinder, is used to drive the material cylinder to rotate; A front cover is connected to the front end of the feed cylinder. The front cover has a feeding port that is connected to the feed storage chamber. When the feed cylinder rotates, the fish food inside can move from the feed storage chamber to the feeding port and be discharged.

[0008] Preferably, the mounting cylinder is located between the lamp plate and the material cylinder, and the transmission mechanism includes a drive motor, which is disposed inside the mounting cylinder, and the output shaft of the drive motor is connected to the material cylinder.

[0009] Preferably, the material cylinder includes a cylinder body and a rear cover, the rear cover and the cylinder body are detachably connected, and the rear cover is provided with a recess for engaging with the output shaft of the drive motor.

[0010] Preferably, the outer wall of the rear cover is provided with a plurality of positioning protrusions, and the inner wall of the cylinder is provided with positioning grooves corresponding to the positioning protrusions. The positioning protrusions are inserted into the positioning grooves to achieve positioning connection. The outer wall of the rear cover is also provided with a guide strip, and the cylinder is provided with a guide groove corresponding to the guide strip. The guide strip slides into the guide groove to achieve guiding engagement.

[0011] Preferably, the inner wall of the storage cavity is provided with a spiral protrusion, which extends spirally from the rear end to the front end of the feed cylinder to form a conveying channel for containing and conveying fish food.

[0012] Preferably, a push chamber is provided at the end of the conveying channel, and the push chamber is provided corresponding to the feeding port for pushing fish food out of the feeding port.

[0013] Preferably, two limiting protrusions are symmetrically arranged on the inner wall of the front cover, and an L-shaped channel is correspondingly arranged on the side wall of the front end of the feed cylinder. The L-shaped channel includes an axially extending guide groove and a circumferentially extending stroke groove communicating with the end of the guide groove. The limiting protrusion enters the stroke groove through the guide groove and can slide in the stroke groove. The push chamber is provided with a push opening of a fixed size. By rotating the front cover, the limiting protrusion moves in the stroke groove, thereby adjusting the overlapping area of ​​the feeding port and the push opening, and thus adjusting the effective opening size of the feeding port.

[0014] Preferably, the system further includes a mounting bracket, one end of which is horizontally fixed to the mounting bracket, and the lower end of which is fixed with a clamping assembly for clamping and fixing to the edge of the aquarium.

[0015] Preferably, the lamp plate is located between the mounting cylinder and the material cylinder, and the transmission mechanism includes a drive motor, which is disposed inside the mounting cylinder. A transmission shaft is connected to the output shaft of the drive motor, and the transmission shaft passes through the lamp plate and is connected to the material cylinder through a transmission unit.

[0016] Preferably, the transmission unit includes a connecting sleeve and a positioning sleeve. The positioning sleeve is fixed to one side of the lamp plate, and the connecting sleeve is rotatably connected to the center of the positioning sleeve. The end of the transmission shaft is provided with a non-circular transmission head, and one end of the connecting sleeve is provided with a transmission groove that matches the transmission head. The transmission head is inserted into the transmission groove to form a snap-fit ​​engagement to realize the transmission of power. The other end of the connecting sleeve is connected to the material cylinder.

[0017] Compared with existing technologies, the advantages of this invention are as follows: the lamp panel, as a lighting unit, has a built-in LED light source to provide the necessary lighting environment for the aquarium, and its flat structure design ensures uniform light distribution and illumination range. The mounting cylinder, as an intermediate connecting component, is fixedly connected to the lamp panel at one end and to the feed cylinder at the other end, while accommodating the transmission mechanism within its internal cavity. This structural arrangement makes full use of the internal space of the device, effectively protecting the transmission components and avoiding the risk of failure caused by exposure.

[0018] The feed hopper has a storage chamber inside, providing space for fish food. Its capacity is designed to meet the automatic feeding needs for several days. The transmission mechanism is installed inside the mounting cylinder and provides rotational power to the feed hopper via a motor or other drive. When the transmission mechanism is working, the feed hopper rotates under the driving force, and the fish food in the storage chamber is stably conveyed to the front discharge position as the feed hopper rotates. When the feeding port is in the downward position, the fish food can fall into the water naturally due to gravity.

[0019] The front cover is connected to the front end of the feed cylinder, forming a closed structure of the feed storage chamber. The connection between the feeding port and the feed storage chamber ensures a smooth path for fish food from storage to delivery. The adjustment of the opening size directly determines the amount of feed delivered per unit time, thus achieving the functional requirement of quantitative feeding.

[0020] This integrated design combines functions that originally required two separate devices into one unit, saving installation space, simplifying equipment configuration, and improving overall reliability and economy. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example 1: As shown in the figure, a fish tank light with a feeding function includes a light panel 1, and also includes... Mounting cylinder 2, one end of which is connected to lamp panel 1; The feed cylinder 3 is rotatably connected to the mounting cylinder 2, and the feed cylinder 3 is provided with a feed storage chamber 4 for holding fish food; The transmission mechanism 5 is connected to the material cylinder 3 and is used to drive the material cylinder 3 to rotate; The front cover 6 is connected to the front end of the feed cylinder 3. The front cover 6 is provided with a feeding port 7, which is connected to the storage chamber 4. When the feed cylinder 3 rotates, the fish food inside it can move from the storage chamber 4 to the feeding port 7 and be discharged.

[0025] This device integrates the lighting and automatic feeding devices into a single structure. The light panel 1, mounting cylinder 2, and feed cylinder 3 are arranged along the same axis, forming a compact rod-shaped shape. This design solves the problem of traditional separate devices occupying too much space on top of the aquarium. This device only requires one installation position to achieve both lighting and feeding functions, greatly improving space utilization efficiency. It is especially suitable for small aquariums or environments with limited space.

[0026] This device also features a unified control panel on the lamp panel 1. The control panel is electrically connected to the lamp panel 1 via an internal control circuit and transmission mechanism 5, thereby enabling centralized control of lighting and feeding functions. Users can control the switching on and off of lights, adjust brightness, set color temperature, and control the timing of feeding through a single control interface. This integrated control method not only simplifies the operation process but also creates conditions for intelligent linkage between lighting and feeding. For example, it can be set to automatically enhance lighting during feeding to increase the fish's feeding enthusiasm.

[0027] In this embodiment, the mounting cylinder 2 is located between the lamp plate 1 and the material cylinder 3. The transmission mechanism 5 includes a drive motor 8, which is installed inside the mounting cylinder 2. The output shaft 9 of the drive motor 8 is connected to the material cylinder 3.

[0028] The drive motor 8 is placed inside the mounting cylinder 2 to form a closed arrangement. The cylinder wall structure provides a stable mounting platform for the motor and also acts as a protective cover, effectively blocking external moisture and splashing water droplets from corroding the motor, extending the service life of the motor and reducing the failure rate.

[0029] During operation, the control circuit sends a control signal to the drive motor 8. The motor drives the feed cylinder 3 to rotate according to the preset speed and direction. The rotation of the feed cylinder 3 causes the fish food in the storage chamber 4 to move circumferentially. Combined with the effect of gravity, the food is gradually transported towards the feeding port 7, thereby realizing timed and quantitative feeding.

[0030] In this embodiment, the material cylinder 3 includes a cylinder body 10 and a rear cover 11. The rear cover 11 is detachably connected to the cylinder body 10. The rear cover 11 is provided with a recess 12, which is used to connect with the output shaft 9 of the drive motor 8.

[0031] The detachable connection between the back cover 11 and the cylinder 10 allows users to easily open the feed cylinder 3 to add fish food and clean the inside without disassembling the entire device, greatly simplifying daily maintenance. This split structure also facilitates the inspection and cleaning of the inside of the feed storage chamber 4, avoiding the accumulation of fish food residue or the problem of moisture and clumping that may occur after long-term use, and ensuring the long-term stability of the feeding function.

[0032] The recess 12 forms a shape fit with the output shaft 9 of the drive motor 8, reliably transmitting the motor's rotational motion to the material cylinder 3. The recess 12 can be designed as a D-groove, square groove, or spline groove, matching the corresponding shape of the motor output shaft 9. This ensures effective torque transmission and enables rapid positioning and installation of the material cylinder 3. Compared to threaded or snap-fit ​​connections, this connection method is more reliable in transmitting torque and will not loosen due to long-term use.

[0033] In this embodiment, the outer wall of the rear cover 11 is provided with a plurality of positioning protrusions 13, and the inner wall of the cylinder 10 is provided with positioning grooves 14 corresponding to the positioning protrusions 13. The positioning protrusions 13 are inserted into the positioning grooves 14 to achieve positioning connection. The outer wall of the rear cover 11 is also provided with guide strips 15, and the cylinder 10 is provided with guide grooves 16 corresponding to the guide strips 15. The guide strips 15 slide into the guide grooves 16 to achieve guiding engagement.

[0034] In the above structure, the rear cover 11 and the cylinder 10 adopt a double positioning structure with positioning protrusions 13 and positioning grooves 14, and guide strips 15 and guide grooves 16, which realizes a reliable assembly connection. Specifically, the positioning protrusions 13 are set on the outer side wall of the rear cover 11 and are evenly distributed circumferentially. The corresponding positioning grooves 14 are set at the corresponding positions on the inner wall of the cylinder 10. When the rear cover 11 is inserted into the cylinder 10, multiple positioning protrusions 13 are simultaneously embedded in their respective positioning grooves 14, forming a precise circumferential positioning and axial limiting effect. This multi-point positioning method has better stability than single-point positioning, effectively preventing the rear cover 11 from shaking or falling off during operation, and ensuring the sealing of the storage cavity 4.

[0035] The design of the guide strip 15 and guide groove 16 further enhances the convenience and accuracy of assembly. The guide strip 15 extends axially along the outer wall of the rear cover 11. During the insertion of the rear cover 11 into the cylinder 10, the guide strip 15 first enters the guide groove 16, playing a role in pre-positioning and guiding, guiding the rear cover 11 to be inserted along the correct path, avoiding assembly difficulties caused by blind alignment. At the same time, the cooperation between the guide strip 15 and the guide groove 16 also provides an anti-rotation function, ensuring that the rear cover 11 and the cylinder 10 maintain a fixed relative angle relationship.

[0036] During operation, firstly, the guide strip 15 enters the guide groove 16 to achieve initial alignment and angular orientation. Subsequently, under the guidance, the rear cover 11 continues to penetrate deeper, and the positioning protrusion 13 gradually approaches the positioning groove 14. Finally, the positioning protrusion 13 is fully embedded in the positioning groove 14, achieving final locking. Throughout the process, the guide structure provides path guidance, while the positioning structure provides final fixation. The two work together to ensure the reliability of the connection and achieve quick and convenient assembly and disassembly.

[0037] In this embodiment, a spiral protrusion 17 is provided on the inner wall of the storage cavity 4. The spiral protrusion 17 extends spirally from the rear end to the front end of the cylinder 10 to form a conveying channel 18 for containing and conveying fish food.

[0038] In the above structure, the spiral protrusion 17 is integrally formed with the inner wall of the storage cavity 4, starting from the rear end of the feed cylinder 3 and extending spirally towards the front end along the inner wall. A spiral conveying channel 18 is formed between adjacent spiral protrusions 17. This structural design transforms the storage cavity 4 into a working cavity with active conveying function. When the feed cylinder 3 is rotated by the drive motor 8, the stationary fish food generates relative motion with respect to the rotating spiral protrusion 17, and moves forward along the axial direction under the pushing action of the spiral surface, realizing the functional conversion from storage to conveying.

[0039] During operation, the rotation of the feed cylinder 3 causes the spiral protrusions 17 to generate a circumferential thrust on the fish food. This thrust can be decomposed into axial and tangential components. The axial component pushes the fish food toward the feeding port 7, while the tangential component causes the fish food to tumble within the conveying channel 18, preventing the fish food from clumping or bridging. This spiral conveying method has better controllability than gravity feeding. The conveying speed is directly proportional to the rotation speed of the feed cylinder 3. The conveying volume can be precisely adjusted by controlling the motor speed. At the same time, the presence of the spiral structure allows the feed cylinder 3 to work normally at any installation angle, without being limited by the direction of gravity, thus enhancing the adaptability of the device.

[0040] In this embodiment, a push chamber 19 is provided at the end of the conveying channel 18. The push chamber 19 is correspondingly provided with the feeding port 7 and is used to push fish food out of the feeding port 7.

[0041] In the above structure, the push chamber 19 is located at the front end of the storage chamber 4, receives the fish food conveyed from the spiral conveyor channel 18, and pushes it to the feeding port 7 in an orderly manner. This structural design solves the contradiction between the continuity of spiral conveying and the intermittent feeding at the feeding port 7, ensuring the stability and controllability of the feeding process.

[0042] The volume of the push chamber 19 is typically designed to be 2-5 times the amount of food fed at one time. This allows it to accommodate the fish food delivered by the spiral without causing excessive accumulation. The shape of the push chamber 19 can be designed as a fan-shaped cavity, with its curvature matching the rotation trajectory of the feed cylinder 3. The bottom surface is slightly inclined towards the feeding port 7, using gravity to assist in the discharge of fish food. The inner wall of the push chamber 19 is smooth to reduce the adhesion of fish food and ensure that there is no residue in the chamber after each feeding, thus avoiding the problem of fish food spoilage.

[0043] As the feed cylinder 3 rotates, the push chamber 19 rotates accordingly to the feeding port 7. Fish food inside the chamber falls into the fish tank through the feeding port 7 under the combined action of gravity and centrifugal force. The outlet size of the push chamber 19 matches the opening size of the feeding port 7. The overlapping area between the two can be changed by rotating the front cover 6, thereby controlling the amount of food fed each time. This design makes the adjustment of the feeding amount more intuitive and precise, allowing users to adjust it at any time without disassembling the equipment, according to actual needs.

[0044] In this embodiment, two limiting protrusions 20 are symmetrically arranged on the inner wall of the front cover 6, and an L-shaped channel 21 is correspondingly arranged on the side wall of the front end of the feed cylinder 3. The L-shaped channel 21 includes an axially extending guide groove 22 and a circumferentially extending stroke groove 23 that communicates with the end of the guide groove 22. The limiting protrusions 20 enter the stroke groove 23 through the guide groove 22 and can slide in the stroke groove 23. The push chamber 19 is provided with a push opening 24 of a fixed size. By rotating the front cover 6, the limiting protrusions 20 can move in the stroke groove 23, thereby adjusting the overlapping area of ​​the feeding port 7 and the push opening 24, and thus adjusting the effective opening size of the feeding port 7.

[0045] In this device, the front cover 6 and the material cylinder 3 are connected by a limiting protrusion 20 and an L-shaped channel 21, achieving a combination of ease of assembly and adjustment function. The two limiting protrusions 20 are symmetrically arranged on the inner wall of the front cover 6, forming a stable two-point support to ensure the installation stability of the front cover 6 on the material cylinder 3. The design of the L-shaped channel 21 separates the assembly path from the adjustment path, and the axially extending guide groove 22 provides assembly guidance. The user only needs to align the front cover 6 and push it axially, and the limiting protrusion 20 can smoothly enter the guide groove 22. When the limiting protrusion 20 reaches the end of the guide groove 22, the front cover 6 is rotated to enter the circumferentially extending stroke groove 23, completing the transition from the assembly state to the working state.

[0046] The sliding range of the limiting protrusion 20 within the travel groove 23 determines the rotatable angle of the front cover 6, typically designed to be between 15 and 50 degrees. During this rotation, the feeding port 7 on the front cover 6 changes position relative to the push opening 24 of the push chamber 19, and the overlapping area of ​​the two changes accordingly. When the limiting protrusion 20 is located at one end of the travel groove 23, the feeding port 7 and the push opening 24 are completely overlapped, achieving the maximum opening state; when the limiting protrusion 20 slides to the other end of the travel groove 23, the overlapping area of ​​the feeding port 7 and the push opening 24 is minimized or even completely offset, achieving the minimum opening or closed state. This adjustment method is intuitive and reliable, allowing users to achieve stepless adjustment of the feeding amount through simple rotation operations.

[0047] In this embodiment, a decorative ring 25 is provided at the connection between the front cover 6 and the material cylinder 3.

[0048] The decorative ring 25 has a ring structure and is fitted onto the joint between the front cover 6 and the feed cylinder 3. It effectively covers the assembly gap between the two and functional structures such as the L-shaped channel 21, giving the entire feeding assembly a unified visual effect.

[0049] From a functional perspective, the decorative ring 25 also serves a protective function, blocking the gap between the front cover 6 and the barrel 3, preventing dust and moisture from entering the connection area, protecting the internal limiting protrusion 20 and L-shaped channel 21 from contamination, and ensuring the long-term smooth operation of the adjustment mechanism. The decorative ring 25 also prevents users from accidentally inserting their fingers into the gap during operation, improving safety.

[0050] In this embodiment, the decorative ring 25 can be made of elastic material and fixed to the barrel 3 by interference fit, or it can be designed as a detachable structure for easy cleaning and maintenance. Its inner diameter is precisely matched with the outer diameter of the barrel 3, and its outer diameter is designed to be slightly larger than the diameter of the front cover 6 to form a smooth transition profile.

[0051] In this embodiment, a mounting bracket 26 is also included. One end of the light panel 1 is horizontally fixed on the mounting bracket 26, and the lower end of the mounting bracket 26 is fixed with a clamping component 27 for clamping and fixing to the edge of the fish tank.

[0052] The advantage of this installation method is that it achieves stable installation without any modification to the aquarium, and is suitable for aquariums of various materials, including glass and acrylic. The entire installation process is simple and quick; the user only needs to clamp the clamping component 27 to the edge of the aquarium and adjust the clamping force to complete the fixation. No tools or additional installation accessories are required. Furthermore, this detachable installation facilitates the movement and storage of the device. When cleaning the aquarium or temporarily not in use, the entire device can be easily removed. The height and angle of the mounting bracket 26 can also be designed as needed, allowing the device to adapt to aquariums of different depths, ensuring optimal lighting effects and feeding positions.

[0053] Example 2: As shown in the figure, unlike Example 1, one end of the material cylinder 3 is connected to the lamp plate 1 via a transmission. The lamp plate 1 is located between the mounting cylinder 2 and the material cylinder 3. The transmission mechanism 5 includes a drive motor 8, which is installed inside the mounting cylinder 2. A transmission shaft 28 is connected to the output shaft 9 of the drive motor 8. The transmission shaft 28 passes through the lamp plate 1 and is connected to the material cylinder 3 through a transmission unit.

[0054] This design, by passing the drive shaft 28 through the lamp panel 1 and connecting it to the feed cylinder 3 using a transmission unit, effectively solves the spatial conflict between the lighting and feeding functions. This allows the lamp panel 1 to better perform its lighting function while ensuring the normal operation of the feeding system. Compared to the direct connection method in Embodiment 1, this structure offers greater design flexibility, allowing an appropriate distance to be maintained between the lamp panel 1 and the feed cylinder 3. This avoids the feed cylinder 3 blocking the light and facilitates user observation and operation of the feeding system. The introduction of the transmission unit not only achieves reliable power transmission but also has a certain degree of shock absorption and buffering, reducing the impact of vibration from the drive motor 8 during operation on the lamp panel 1 and the overall structure, thus improving the product's stability and service life.

[0055] In this embodiment, the transmission unit includes a connecting sleeve 30 and a positioning sleeve 31. The positioning sleeve 31 is fixed on one side of the lamp plate 1. The connecting sleeve 30 is rotatably connected to the center of the positioning sleeve 31. The end of the transmission shaft 28 is provided with a non-circular transmission head 29. One end of the connecting sleeve 30 is provided with a transmission groove 32 that matches the transmission head 29. The transmission head 29 is inserted into the transmission groove 32 to form a snap-fit ​​engagement, thereby realizing the transmission of power. The other end of the connecting sleeve 30 is connected to the material cylinder 3.

[0056] In the above structure, the positioning sleeve 31 serves as a basic support component fixed on the lamp plate 1, providing a stable installation reference and support for the entire transmission system, ensuring coaxiality and stability during transmission. The connecting sleeve 30 is installed in the center of the positioning sleeve 31 using a rotatable connection method. This design not only ensures the flexibility of rotation but also achieves precise radial positioning and axial constraint through the positioning sleeve 31.

[0057] The transmission unit uses a non-circular transmission head 29 and a matching transmission groove 32 to form a snap-fit ​​connection. Compared with traditional gear meshing and other transmission methods, this structure firstly greatly simplifies the assembly process, allowing the transmission shaft and connecting sleeve to be quickly inserted in the axial direction to achieve power connection, reducing the alignment accuracy requirements, effectively improving production assembly efficiency, and this direct snap-fit ​​connection ensures efficient and stable power transmission without slippage, avoiding the gap problems that may be caused by gear wear.

[0058] In this embodiment, the mounting cylinder 2 is horizontally fixed on the mounting bracket 26. The lower end of the mounting bracket 26 is fixed with a clamping component 27 for clamping and fixing to the edge of the fish tank. The mounting cylinder 2 is also equipped with a battery module powered by the drive motor 8.

[0059] When the user activates the feeding function, the drive motor 8 starts running. The output shaft 9 of the drive motor 8 drives the transmission shaft 28 connected to it to rotate synchronously. After the transmission shaft 28 passes through the light panel 1, the transmission head 29 at its front end transmits the rotational power of the motor to the connecting sleeve 30 through the engagement of the transmission groove 32. The connecting sleeve 30 rotates smoothly under the support and constraint of the positioning sleeve 31, thereby driving the feed cylinder 3, which is fixedly connected to it, to rotate as a whole. As the feed cylinder 3 rotates, the spiral protrusions 17 on the inner wall of the storage chamber 4 begin to function, pushing the fish food stored in the feed cylinder 3 forward along the spiral conveying channel 18. Guided by the spiral protrusions 17, the fish food gradually moves to the push chamber 19 and is finally pushed out through the feeding port 7, completing the automatic feeding process.

[0060] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
