Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, and in particular to a flow-turbulating structure, a heat exchange component and a water heater. Background Art

[0002] A water heater is a device that uses various physical principles to heat cold water over a period of time. Gas water heaters are a popular choice among users due to their fast heating speed, energy efficiency, and safety.

[0003] The heat exchange components of gas water heaters are prone to supercooling and boiling during use, causing water to vaporize on the inner walls of the heat exchange tubes. This vaporization produces a clattering noise, which can be excessive and affect the user experience.

[0004] In order to avoid excessive noise during the operation of the gas water heater, a spoiler spring assembly is generally provided in the heat exchange tube of the heat exchange assembly in the prior art. Figure 1-Figure 3 As shown, the spoiler spring assembly includes a spring 10 and a spoiler 20 mounted on the inner ring of the spring 10. The spoiler 20 is generally twisted in a spiral shape. After water flows through the spoiler spring assembly, the water flow changes from laminar flow to turbulent flow, reducing water vaporization and thus reducing the water vaporization noise.

[0005] When using the above-mentioned spoiler spring assembly, the cost of the spoiler spring assembly is high because the spring 10 and the spoiler 20 need to be processed and prepared at the same time, which in turn increases the cost of the heat exchange assembly and the gas water heater. Utility Model Content

[0006] One of the technical problems solved by the present invention is to provide a spoiler structure which can reduce costs while ensuring spoiler performance.

[0007] The second technical problem solved by the present invention is to provide a heat exchange component that can reduce costs while ensuring turbulence performance.

[0008] The third technical problem solved by the present invention is to provide a water heater which can reduce costs while ensuring the turbulence performance of the heat exchange component.

[0009] The first technical problem mentioned above is solved by the following technical solution:

[0010] The spoiler structure includes multiple variable-diameter spoiler springs, which are coaxially connected in sequence. The variable-diameter spoiler spring includes a first spring segment and a second spring segment that are coaxially connected. Along the set direction, the outer diameter of the spring coil of the first spring segment gradually decreases, and the outer diameter of the spring coil of the second spring segment gradually increases. The set direction is parallel to the axial direction of the variable-diameter spoiler spring.

[0011] Compared with the background technology, the spoiler structure of the present invention has the following beneficial effects:

[0012] The spoiler structure eliminates the spoiler in the prior art, which can ensure the spoiler performance and eliminate the process of assembling the spoiler, thereby reducing material costs and labor costs.

[0013] This flow-disrupting structure is applied within the heat exchange tubes of a heat exchange assembly and is coaxially arranged with the tubes. Due to the presence of multiple variable-diameter flow-disrupting springs, the outer diameter of the spring coils of the first spring segment gradually decreases, while the outer diameter of the spring coils of the second spring segment gradually increases along a set direction. This arrangement is equivalent to providing multiple obstructions in the water flow path. As the water flows through the obstructions, it bypasses them, making the flow more complex and disordered, disrupting the laminar structure of the water flow and transforming it into a turbulent state, reducing water vaporization and, in turn, vaporization noise, thereby ensuring flow-disrupting performance. Simultaneously, during the flow of water, the spring coils of the first and second spring segments collide with bubbles carried by the water flow. The rebound action of the spring coils disperses or even eliminates the bubbles, thereby reducing vaporization noise during operation of the heat exchange assembly. Furthermore, this flow-disrupting structure eliminates the spoiler plate used in the prior art, eliminating the process of assembling the spoiler plate and reducing material and labor costs.

[0014] In one embodiment, the flow-disturbing structure further includes an equal-diameter support spring, the outer diameter of which is configured to be the same as the inner diameter of the heat exchange tube of the heat exchange assembly, and one of the equal-diameter support springs is connected between at least two adjacent variable-diameter flow-disturbing springs.

[0015] In one embodiment, the equal-diameter support spring is a cylindrical helical spring.

[0016] In one embodiment, a constant diameter support spring is connected between any two adjacent variable diameter spoiler springs.

[0017] In one embodiment, the outer diameter of the spring coil of the first spring segment ranges from 4 mm to 10.8 mm; and / or

[0018] The outer diameter of the spring coil of the second spring section ranges from 4 mm to 10.8 mm.

[0019] In one embodiment, the pitch of the first spring segment is proportional to the outer diameter of the spring coil of the first spring segment; and / or

[0020] The pitch of the second spring segment is proportional to the outer diameter of the spring coil of the second spring segment.

[0021] In one embodiment, along the set direction, the outer diameter of the spring coil of the first spring segment changes evenly and gradually; and / or

[0022] Along the set direction, the outer diameter of the spring coil of the second spring segment changes evenly and gradually.

[0023] In one embodiment, along the set direction, the outer diameter of the spring coil of the first spring segment changes evenly and gradually within the range of 4 mm to 10.8 mm;

[0024] Along the set direction, the outer diameter of the spring coil of the second spring segment changes evenly and gradually within the range of 4mm-10.8mm.

[0025] The second technical problem mentioned above is solved by the following technical solution:

[0026] Heat exchange components, including:

[0027] heat exchange tubes;

[0028] The above-mentioned flow-disturbing structure is arranged inside the heat exchange tube along the axial direction of the heat exchange tube.

[0029] Compared with the background technology, the heat exchange component of the present invention has the following beneficial effects:

[0030] The heat exchange assembly, by arranging the above-mentioned flow-turbulating structure in the heat exchange tube, can not only ensure the flow-turbulating performance, but also save the process of assembling the spoiler, thereby reducing material cost and labor cost.

[0031] When the heat exchange assembly is in use, a flow-disrupting structure is disposed within the heat exchange tube along the axial direction. Due to the presence of multiple variable-diameter flow-disrupting springs, the outer diameter of the spring coils of the first spring segment gradually decreases, while the outer diameter of the spring coils of the second spring segment gradually increases along a set direction. This arrangement is equivalent to providing multiple obstructions in the water flow path. When the water flows through the obstructions, it bypasses them, making the flow more complex and disordered, disrupting the laminar structure of the water flow and causing it to become turbulent, reducing water vaporization and, in turn, vaporization noise, thereby ensuring flow-disrupting performance. Simultaneously, during the flow of water, the spring coils of the first and second spring segments collide with bubbles carried by the water flow. The rebound effect of the spring coils disperses or even eliminates the bubbles, thereby reducing vaporization noise during operation of the heat exchange assembly. Furthermore, the heat exchange assembly employs the aforementioned flow-disrupting structure, eliminating the spoiler plate used in the prior art. This eliminates the need for assembling the spoiler plate and reduces material and labor costs.

[0032] The third technical problem mentioned above is solved by the following technical solution:

[0033] Water heater, including:

[0034] heat exchange room;

[0035] The above-mentioned heat exchange component is arranged in the heat exchange chamber and exchanges heat with the high-temperature flue gas in the heat exchange chamber.

[0036] Compared with the background technology, the water heater of the present invention has the following beneficial effects:

[0037] The water heater includes the above-mentioned heat exchange assembly, which can not only ensure the turbulence performance, but also save the process of assembling the spoiler, thereby reducing material costs and labor costs.

[0038] During operation, the water heater utilizes multiple variable-diameter flow-disrupting springs within the heat exchange tubes of the heat exchange assembly. Along a set direction, the outer diameter of the spring coils of the first spring segment gradually decreases, while the outer diameter of the second spring segment gradually increases. This configuration is equivalent to providing multiple obstructions along the water flow path. As the water flows through the obstructions, it bypasses them, making the flow more complex and disordered, disrupting the laminar structure of the water flow and transforming it into a turbulent state. This reduces water vaporization and, in turn, vaporization noise, thereby ensuring flow-disrupting performance. Simultaneously, during the flow of water, the spring coils of the first and second spring segments collide with bubbles carried in the water flow. The rebound of the spring coils disperses or even eliminates the bubbles, thereby reducing vaporization noise during operation of the heat exchange assembly.

[0039] In addition, the water heater adopts the above-mentioned heat exchange component, eliminating the spoiler in the prior art, which not only saves the process of assembling the spoiler, but also reduces material costs and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Example 1

[0062] This embodiment provides a flow-disrupting structure that can be applied to a water heater's heat exchange assembly and installed within the heat exchange tubes of the assembly to reduce noise during operation. Furthermore, this flow-disrupting structure effectively disrupts the flow of water through the heat exchange tubes without the need for springs, as is conventionally the case. This ensures flow-disrupting performance while eliminating the need for assembly of a spoiler, reducing material and labor costs.

[0063] Specifically, the water heater is a gas water heater. Gas water heaters heat quickly, quickly heating water to the user's desired temperature. They use natural gas or liquefied petroleum gas as fuel, making them more energy-efficient and efficient than traditional electric water heaters. Furthermore, gas water heaters are generally equipped with safety features, such as smoke alarms and explosion protection devices, to ensure user safety.

[0064] Specifically, see Figure 4-Figure 7 In this embodiment, the spoiler structure includes a plurality of variable-diameter spoiler springs 1. The plurality of variable-diameter spoiler springs 1 are coaxially connected in sequence.

[0065] See also Figures 8-10 In this embodiment, the variable diameter spoiler spring 1 includes a first spring segment 11 and a second spring segment 12 that are coaxially connected. Along the set direction, the outer diameter of the spring coil of the first spring segment 11 gradually decreases, and the outer diameter of the spring coil of the second spring segment 12 gradually increases. The set direction is parallel to the axial direction of the variable diameter spoiler spring 1.

[0066] For example, Figure 8 Taking the shown orientation as an example, the setting direction is from top to bottom and parallel to the axial direction of the variable diameter spoiler spring 1.

[0067] The flow-disrupting structure provided in this embodiment is applied to the heat exchange tube of the heat exchange assembly and is coaxially arranged with the heat exchange tube. Due to the presence of multiple variable-diameter flow-disrupting springs 1, and along the set direction, the outer diameter of the spring coil of the first spring segment 11 gradually decreases, and the outer diameter of the spring coil of the second spring segment 12 gradually increases. Such an arrangement is equivalent to setting multiple obstructions on the flow path of the water flow. When the water flows through the obstructions, it will bypass the obstructions, thereby making the flow of the water more complex and disordered, destroying the laminar flow structure of the water flow, causing the water flow to become turbulent, reducing the vaporization of water, and further reducing the vaporization noise, thereby ensuring the flow-disrupting performance.

[0068] At the same time, during the flow of water, the spring coils of the first spring segment 11 and the second spring segment 12 will collide with the bubbles carried in the water flow. Under the rebound effect of the spring coils, the bubbles will be broken up or even disappear, thereby reducing the vaporization noise of the heat exchange component during operation.

[0069] In addition, the spoiler structure is adopted, and the spoiler in the prior art is omitted, which can not only save the process of assembling the spoiler, but also reduce material costs and labor costs.

[0070] Furthermore, in one of the embodiments, in order to ensure the stability of the spoiler structure during installation in the heat exchange tube, in this embodiment, the spoiler structure also includes an equal-diameter support spring 2, the outer diameter of the equal-diameter support spring 2 is configured to be the same as the inner diameter of the heat exchange tube of the heat exchange assembly, and an equal-diameter support spring 2 is connected between at least two adjacent variable-diameter spoiler springs 1.

[0071] With this arrangement, when the flow-disturbing structure is installed in the heat exchange tube, the outer side of the equal-diameter support spring 2 abuts against the inner wall of the heat exchange tube, limiting the flow-disturbing structure and ensuring that the flow-disturbing structure can stably disturb the water flow.

[0072] Optionally, in one embodiment, the equal-diameter support spring 2 is a cylindrical coil spring. This configuration allows, on the one hand, the outer surface of the coil of the equal-diameter support spring 2 to abut against the inner wall of the heat exchange tube, ensuring the installation stability of the flow-turbine structure; on the other hand, the coil of the equal-diameter support spring 2 can also collide with bubbles carried in the water flow. The rebound effect of the coil of the equal-diameter support spring 2 will disperse or even eliminate the bubbles, thereby reducing the vaporization noise of the heat exchange component during operation.

[0073] Furthermore, in order to further ensure the stability of the installation state of the spoiler structure, in one embodiment, a constant diameter support spring 2 is connected between any two adjacent variable diameter spoiler springs 1.

[0074] Such an arrangement enables the variable diameter spoiler spring 1 and the equal diameter support spring 2 to be alternately arranged along the axial direction of the spoiler structure, thereby ensuring the structural stability of the spoiler structure, and thus ensuring the spoiler effect of each variable diameter spoiler spring 1. At the same time, the equal diameter support spring 2 can play a role in breaking up bubbles and reducing vaporization noise.

[0075] Optionally, in one embodiment, the outer diameter of the spring coil of the first spring segment 11 is in the range of 4 mm to 10.8 mm; and / or

[0076] The outer diameter of the spring coil of the second spring section 12 is in the range of 4 mm to 10.8 mm.

[0077] Specifically, the outer diameter of the spring coil of the first spring segment 11 ranges from 4 mm to 10.8 mm. Generally, the inner diameter of the heat exchange tube of the heat exchange assembly is 10.8 mm, so the maximum outer diameter of the spring coil of the first spring segment 11 is 10.8 mm. If the outer diameter of the spring coil of the first spring segment 11 is less than 4 mm, its flow-disturbing effect will be significantly reduced. Therefore, the minimum outer diameter of the spring coil of the first spring segment 11 is 4 mm.

[0078] Optionally, the outer diameter of the spring coil of the first spring segment 11 can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.4 mm, or 10.8 mm, and the outer diameter of the spring coil of the first spring segment 11 gradually decreases along a set direction. Of course, in other embodiments, the outer diameter of the spring coil of the first spring segment 11 can also be set to other values as needed.

[0079] Specifically, the outer diameter of the spring coil of the second spring segment 12 ranges from 4 mm to 10.8 mm. Generally, the inner diameter of the heat exchange tube of the heat exchange assembly is 10.8 mm, so the maximum outer diameter of the spring coil of the second spring segment 12 is 10.8 mm. If the outer diameter of the spring coil of the second spring segment 12 is less than 4 mm, its flow-disturbing effect will be significantly reduced. Therefore, the minimum outer diameter of the spring coil of the second spring segment 12 is 4 mm.

[0080] Optionally, the outer diameter of the spring coil of the second spring segment 12 can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.4 mm, or 10.8 mm, and the outer diameter of the second spring segment 12 gradually increases along a set direction. Of course, in other embodiments, the outer diameter of the spring coil of the second spring segment 12 can also be set to other values as needed.

[0081] Furthermore, in one embodiment, the pitch of the first spring segment 11 is proportional to the outer diameter of the spring coil of the first spring segment 11; and / or

[0082] The pitch of the second spring segment 12 is proportional to the outer diameter of the spring coil of the second spring segment 12 .

[0083] Specifically, the pitch of the first spring segment 11 is proportional to the outer diameter of the spring coil of the first spring segment 11 ; that is, the larger the outer diameter of the spring coil of the first spring segment 11 , the larger the pitch, so as to ensure effective turbulence.

[0084] Specifically, the pitch of the second spring segment 12 is proportional to the outer diameter of the spring coil of the second spring segment 12 ; that is, the larger the outer diameter of the spring coil of the second spring segment 12 , the larger the pitch, so as to ensure effective turbulence.

[0085] Example 2

[0086] This embodiment provides a spoiler structure, which can be applied to the heat exchange component of the water heater and installed in the heat exchange tube of the heat exchange component to reduce the noise of the heat exchange component during operation, ensure the spoiler effect and reduce costs.

[0087] Specifically, the water heater is a gas water heater. Gas water heaters heat quickly, quickly heating water to the user's desired temperature. They use natural gas or liquefied petroleum gas as fuel, making them more energy-efficient and efficient than traditional electric water heaters. Furthermore, gas water heaters are generally equipped with safety features, such as smoke alarms and explosion protection devices, to ensure user safety.

[0088] Specifically, see Figure 4-Figure 7 In this embodiment, the spoiler structure includes a plurality of variable-diameter spoiler springs 1. The plurality of variable-diameter spoiler springs 1 are coaxially connected in sequence.

[0089] See also Figures 8-10 In this embodiment, the variable diameter spoiler spring 1 includes a first spring segment 11 and a second spring segment 12 that are coaxially connected. Along the set direction, the outer diameter of the spring coil of the first spring segment 11 gradually decreases, and the outer diameter of the spring coil of the second spring segment 12 gradually increases. The set direction is parallel to the axial direction of the variable diameter spoiler spring 1.

[0090] The flow-disrupting structure provided in this embodiment is applied to the heat exchange tube of the heat exchange assembly and is coaxially arranged with the heat exchange tube. Due to the presence of multiple variable-diameter flow-disrupting springs 1, and along the set direction, the outer diameter of the spring coil of the first spring segment 11 gradually decreases, and the outer diameter of the spring coil of the second spring segment 12 gradually increases. Such an arrangement is equivalent to setting multiple obstructions on the flow path of the water flow. When the water flows through the obstructions, it will bypass the obstructions, thereby making the flow of the water more complex and disordered, destroying the laminar flow structure of the water flow, causing the water flow to become turbulent, reducing the vaporization of water, and further reducing the vaporization noise, thereby ensuring the flow-disrupting performance.

[0091] At the same time, during the flow of water, the spring coils of the first spring segment 11 and the second spring segment 12 will collide with the bubbles carried in the water flow. Under the rebound effect of the spring coils, the bubbles will be broken up or even disappear, thereby reducing the vaporization noise of the heat exchange component during operation.

[0092] In addition, the spoiler structure is adopted, and the spoiler in the prior art is omitted, which can not only save the process of assembling the spoiler, but also reduce material costs and labor costs.

[0093] Optionally, in one embodiment, the outer diameter of the spring coil of the first spring segment 11 changes gradually and evenly along the set direction; and / or

[0094] Along the set direction, the outer diameter of the spring coil of the second spring segment 12 changes evenly and gradually.

[0095] Along the set direction, the outer diameter of the spring coil of the first spring segment 11 changes gradually and evenly, thereby ensuring the uniformity of the first spring segment 11 in disturbing the water flow.

[0096] Likewise, along the set direction, the outer diameter of the spring coil of the second spring segment 12 changes gradually and evenly, thereby ensuring the uniformity of the second spring segment 12 in disturbing the water flow.

[0097] More specifically, in one embodiment, along a set direction, the outer diameter of the spring coil of the first spring segment 11 changes evenly and gradually within a range of 4 mm to 10.8 mm.

[0098] Along the set direction, the outer diameter of the spring coil of the second spring segment 12 changes evenly and gradually within the range of 4 mm to 10.8 mm.

[0099] Specifically, the outer diameter of the spring coil of the first spring segment 11 ranges from 4 mm to 10.8 mm. Generally, the inner diameter of the heat exchange tube of the heat exchange assembly is 10.8 mm, so the maximum outer diameter of the spring coil of the first spring segment 11 is 10.8 mm. If the outer diameter of the spring coil of the first spring segment 11 is less than 4 mm, its flow-disturbing effect will be significantly reduced. Therefore, the minimum outer diameter of the spring coil of the first spring segment 11 is 4 mm.

[0100] Optionally, the outer diameter of the spring coil of the first spring segment 11 can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.4 mm, or 10.8 mm, and the outer diameter of the spring coil of the first spring segment 11 gradually decreases along a set direction. Of course, in other embodiments, the outer diameter of the spring coil of the first spring segment 11 can also be set to other values as needed.

[0101] Specifically, the outer diameter of the spring coil of the second spring segment 12 ranges from 4 mm to 10.8 mm. Generally, the inner diameter of the heat exchange tube of the heat exchange assembly is 10.8 mm, so the maximum outer diameter of the spring coil of the second spring segment 12 is 10.8 mm. If the outer diameter of the spring coil of the second spring segment 12 is less than 4 mm, its flow-disturbing effect will be significantly reduced. Therefore, the minimum outer diameter of the spring coil of the second spring segment 12 is 4 mm.

[0102] Optionally, the outer diameter of the spring coil of the second spring segment 12 can be 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.4 mm, or 10.8 mm, and the outer diameter of the second spring segment 12 gradually increases along a set direction. Of course, in other embodiments, the outer diameter of the spring coil of the second spring segment 12 can also be set to other values as needed.

[0103] Of course, in other embodiments, the maximum outer diameters of the spring coils of the first spring segment 11 and the second spring segment 12 may also be set to other values according to the inner diameters of the heat exchange tubes of the heat exchange assembly.

[0104] Example 3

[0105] This embodiment provides a heat exchange component.

[0106] Specifically, the heat exchange assembly includes a heat exchange tube and the flow-disturbing structure of the first or second embodiment, and the flow-disturbing structure is arranged in the heat exchange tube along the axial direction of the heat exchange tube.

[0107] The heat exchange assembly provided in this embodiment can ensure the flow disturbance performance by providing a flow disturbance structure in the heat exchange tube, and can also save the process of assembling the spoiler, thereby reducing material cost and labor cost.

[0108] When the heat exchange assembly is in use, the flow-disrupting structure is arranged inside the heat exchange tube along the axial direction of the heat exchange tube. Due to the presence of multiple variable-diameter flow-disrupting springs 1, and along the set direction, the outer diameter of the spring coil of the first spring segment 11 gradually decreases, and the outer diameter of the second spring segment 12 gradually increases. This arrangement is equivalent to setting multiple obstructions in the flow path of the water flow. When the water flows through the obstructions, it will bypass the obstructions, thereby making the flow of the water more complex and disordered, destroying the laminar flow structure of the water flow, causing the water flow to become turbulent, reducing water vaporization, and thus reducing vaporization noise, thereby ensuring the flow-disrupting performance.

[0109] At the same time, during the flow of water, the spring coils of the first spring segment 11 and the second spring segment 12 will collide with the bubbles carried in the water flow. Under the rebound effect of the spring coils, the bubbles will be broken up or even disappear, thereby reducing the vaporization noise of the heat exchange component during operation.

[0110] In addition, the spoiler structure is adopted, and the spoiler in the prior art is omitted, which can not only save the process of assembling the spoiler, but also reduce material costs and labor costs.

[0111] Example 4

[0112] This embodiment provides a water heater.

[0113] Specifically, the water heater is a gas water heater.

[0114] The water heater includes a heat exchange chamber and the heat exchange component of the third embodiment. The heat exchange component is arranged in the heat exchange chamber and exchanges heat with the high-temperature flue gas in the heat exchange chamber.

[0115] When the water heater provided in this embodiment is in operation, due to the presence of multiple variable-diameter flow-disturbing springs 1 in the heat exchange tube of the heat exchange assembly, and along the set direction, the outer diameter of the spring coil of the first spring segment 11 gradually decreases, and the outer diameter of the spring coil of the second spring segment 12 gradually increases. Such a setting is equivalent to setting multiple obstructions on the flow path of the water flow. When the water flow passes through the obstruction, it will bypass the obstruction, thereby making the flow of the water flow more complicated and disordered, destroying the laminar structure of the water flow, and making the water flow into a turbulent state, reducing the vaporization of water, and then reducing the vaporization noise, thereby ensuring the flow disturbance performance.

[0116] At the same time, during the flow of water, the spring coils of the first spring segment 11 and the second spring segment 12 will collide with the bubbles carried in the water flow. Under the rebound effect of the spring coils, the bubbles will be broken up or even disappear, thereby reducing the vaporization noise of the heat exchange component during operation.

[0117] In addition, the spoiler structure can eliminate the spoiler in the prior art while ensuring the spoiler performance, thereby eliminating the process of assembling the spoiler and reducing material and labor costs.

[0118] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0119] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
