Description

Technical Field

[0001] This utility model relates to the field of steam device technology, and in particular to a steam generating device. Background Technology

[0002] Current steam generators typically employ the principle of communicating vessels. During operation, high-pressure steam is generated within the steam generator. However, once a critical state is reached and the steam pressure inside the cavity becomes excessive, the water inside the cavity will be forced back into the water storage structure connected to the inlet pipe under the conditions of the communicating vessel principle, thereby affecting the steam generation effect of the steam generator.

[0003] Taking a garment steamer as an example, after the water in the hot pot is squeezed out, the steam decreases, and the pressure inside the hot pot decreases accordingly. When the pressure drops to a certain level, the water in the water tank quickly rushes back into the hot pot, and the temperature of the hot pot drops rapidly, making it impossible to generate enough steam quickly, resulting in a steam interruption. Utility Model Content

[0004] The main purpose of this invention is to propose a steam generating device that aims to improve the problem of steam interruption in existing steam generating devices that use the communicating vessel principle.

[0005] To achieve the above objectives, the steam generating device proposed in this utility model includes:

[0006] A steam generating chamber for producing steam;

[0007] A water supply assembly includes a water tank and a mounting base. The water tank is mounted on the mounting base. The mounting base has a water passage hole corresponding to the water inlet of the water tank. The water passage hole is connected to the steam generating chamber via a connecting pipe. The water tank supplies water to the steam generating chamber sequentially through the water passage hole and the connecting pipe.

[0008] A sealing structure is disposed between the water tank and the mounting base, and is arranged in a ring shape. The sealing structure is used to form an interference seal between the water tank and the mounting base.

[0009] In one embodiment, one of the water tank and the mounting base is provided with a docking part, and the other is provided with a mating part. The water tank and the mounting base are connected through the docking part and the mating part.

[0010] The sealing structure is located between the mating surfaces of the docking portion and the mating portion.

[0011] In one embodiment, the docking portion and the mating portion are sleeved together.

[0012] The sealing structure is disposed between the side surfaces of the mating portion and the fitting portion.

[0013] In one embodiment, the water supply port of the water tank is configured as the mating part;

[0014] The mounting base has a first extension protruding from one end facing the water tank, and the first extension extends at least partially into the water supply port to form the docking part;

[0015] The sealing structure is located on the side surface of the first extension and abuts against the inner sidewall of the water supply port.

[0016] In one embodiment, the water passage hole is configured as the mating part;

[0017] The water tank has a second extension protruding from one end facing the mounting base, and the second extension extends at least partially into the water passage hole to form the docking part;

[0018] The sealing structure is located on the side surface of the second extension and abuts against the wall of the water passage.

[0019] In one embodiment, one end of the docking portion and one end of the mating portion are mated and connected.

[0020] At least a portion of the sealing structure is located between the end faces of the mating portion and the fitting portion that are connected to each other.

[0021] In one embodiment, the mounting base is configured as the docking portion;

[0022] The water tank is configured as the mating part;

[0023] The sealing structure has a first end and a second end that are arranged opposite to each other. The first end is connected to the water passage hole, and the second end extends from the opening of the water passage hole to the space between the water tank and the mounting base, so as to abut against the water tank and the mounting base.

[0024] In one embodiment, the second end is bent toward the first end.

[0025] In one embodiment, the water supply port of the water tank is provided with a sealing part, which has a sealed state of sealing the water supply port and a connected state of opening the water supply port;

[0026] The water passage is provided with a contact part, which is used to drive the blocking part to switch from the blocking state to the connecting state when the water tank is installed on the mounting base;

[0027] The first end of the sealing structure is located between the contact portion and the wall of the water passage hole, and is connected to the contact portion. The sealing structure has a through hole for water passage.

[0028] In one embodiment, the steam generating device includes a garment steamer.

[0029] In the technical solution of this utility model, when the steam generating device is working normally, the water tank operates to supply water to the steam generating chamber. The water in the water tank flows sequentially through the water passage and the connecting pipe to the steam generating chamber. The steam generating chamber heats the water to evaporate it and generate steam. During the continuous operation of the steam generating chamber, the steam pressure inside the steam generating chamber continuously increases. When the steam pressure inside the steam generating chamber rises to a critical value, the water in the steam generating chamber will be forced back from the steam generating chamber to the steam generating chamber under the action of air pressure. Within the connecting pipe and the water passage, the sealing structure between the water tank and the mounting base creates an interference seal. This seal isolates the water passage from the atmosphere, preventing backflow from the steam generating chamber and thus preventing leakage between the water tank and the mounting base. The water can only flow back into the water tank, and because the water tank is under positive pressure, this pressure further prevents backflow. This design reduces or even eliminates backflow from the steam generating chamber, ensuring temperature stability and preventing steam interruption. Attached Figure Description

[0044] This invention proposes a steam generating device, which aims to improve the problem of steam interruption in existing steam generating devices that use the communicating vessel principle.

[0045] Please see Figure 1-2 In one embodiment of this utility model, the steam generating device 100 includes a steam generating chamber 1, a water supply assembly 2, and a sealing structure 3. The steam generating chamber 1 is used to generate steam. The water supply assembly 2 includes a water tank 21 and a mounting base 22. The water tank 21 is mounted on the mounting base 22. The mounting base 22 has a water passage hole 24 corresponding to the water supply port 23 of the water tank 21. The water passage hole 24 is connected to the steam generating chamber 1 through a connecting pipe 4. The water tank 21 is used to supply water to the steam generating chamber 1 through the water passage hole 24 and the connecting pipe 4 in sequence. The sealing structure 3 is disposed between the water tank 21 and the mounting base 22 and is arranged in a ring shape. The sealing structure 3 is used to form an interference seal between the water tank 21 and the mounting base 22.

[0046] In the technical solution of this utility model, when the steam generator 100 is working normally, the water tank 21 operates to supply water to the steam generating chamber 1. The water in the water tank 21 flows sequentially through the water passage 24 and the connecting pipe 4 into the steam generating chamber 1. The steam generating chamber 1 heats the water to evaporate it and generate steam. During the continuous operation of the steam generating chamber 1, the steam pressure inside the steam generating chamber 1 continuously increases. When the steam pressure inside the steam generating chamber 1 rises to a critical value, the water in the steam generating chamber 1 will be forced back from the steam generating chamber 1 to the connecting pipe 4 under the action of air pressure. Within the water passage 24, the sealing structure 3, located between the water tank 21 and the mounting base 22, forms an interference seal. This seal isolates the water passage 24 from the atmosphere, preventing backflow of water from the steam generating chamber 1 and preventing leakage between the water tank 21 and the mounting base 22. The water can only flow back into the water tank 21, which is under positive pressure. This pressure further prevents backflow. This configuration reduces or even eliminates backflow from the steam generating chamber 1, ensuring temperature stability and preventing steam interruption.

[0047] It is understood that in this utility model, since the sealing structure 3 is arranged in a ring shape, the interference seal formed by the sealing structure 3 between the water tank 21 and the mounting base 22 is also arranged in a ring shape. In this way, the ring-shaped interference seal can be arranged around the periphery of the water supply port 23 and the water passage hole 24, thereby achieving a waterproof seal without dead angles and ensuring the ability to block backflow water.

[0048] Of course, this utility model does not limit the specific structural form of the sealing structure 3. In one embodiment of this utility model, the sealing structure 3 can be set as a sealing ring, and the material of the sealing ring is set as rubber, so that the sealing ring can be elastically set in the direction of the water tank 21 and the mounting base 22 facing each other, so as to ensure the sealing performance of the hard seal formed by the sealing structure 3.

[0049] In another embodiment of this utility model, the sealing structure 3 can also be configured as a gasket. With this configuration, the gasket is placed between the mounting base 22 and the water tank 21. Under the mutual pressure between the mounting base 22 and the water tank 21, an interference seal is achieved between the two, which can also achieve isolation from the atmosphere, so as to ensure a waterproof seal between the mounting base 22 and the water tank 21.

[0050] In other embodiments of this utility model, the sealing structure 3 can also be configured as a combined sealing element or other structural form. In actual settings, it can be selected according to the requirements, and this utility model does not impose any restrictions on it.

[0051] Of course, in order to ensure the sealing performance of the sealing structure 3 on the mounting base 22 and the water tank 21, and to ensure the stable connection between the mounting base 22 and the water tank 21, in this utility model, one of the water tank 21 and the mounting base 22 is provided with a docking part, and the other is provided with a mating part. The water tank 21 and the mounting base 22 are connected through the docking part and the mating part. The sealing structure 3 is located between the mating surfaces of the docking part and the mating part. With this configuration, the mounting base 22 and the water tank 21 are connected via the mating part and the connecting part to establish a communication relationship between them. This ensures the stability of the communication between the mounting base 22 and the water tank 21, and ensures that the water tank 21 can continuously and stably supply evaporated water to the steam generating chamber 1 through the water passage 24 and the connecting pipe 4. When the connecting part and the mating part are connected, the sealing structure 3 can form an interference seal between the connecting part and the mating part, thus ensuring the sealing performance between the mating surfaces of the two parts, thereby further ensuring the sealing performance between the mounting base 22 and the water tank 21, and thus blocking the return water from the steam generating chamber 1 to the connecting pipe 4 and the water passage 24, preventing the steam generated by the steam generating chamber 1 from being interrupted.

[0052] In one embodiment of the present invention, the docking part is provided on the mounting base 22, and the mating part is provided on the water tank 21; in another embodiment of the present invention, the mating part is provided on the mounting base 22, and the docking part is provided on the water tank 21.

[0053] To ensure the stability of the mating part and the connecting part, in one embodiment of this utility model, the connecting part and the mating part are sleeved together, and the sealing structure 3 is disposed between the side surfaces of the connecting part and the mating part. In this embodiment, the mating part and the connecting part are connected by sleeve, thereby realizing the connection between the mounting base 22 and the water tank 21. At this time, the sealing structure 3 is located between the two corresponding side surfaces of the mating part and the connecting part, thus achieving an interference seal between the two.

[0054] It is understood that in this utility model, since the sealing structure 3 needs to form a seamless seal around the water supply port 23 and the water passage hole 24 to prevent backflow water from leaking to the outside, the mating part and the connecting part are designed as a sleeve. This ensures that when the sealing structure 3 is located between the two corresponding side surfaces of the mating part and the connecting part, the sealing structure 3 can still achieve an all-round seal around the water supply port 23 and the water passage hole 24, thus ensuring its sealing performance and preventing the steam generated in the steam generating chamber 1 from being interrupted, ensuring the smoothness and quantity of steam generation.

[0055] Of course, this utility model does not limit the specific sleeve form of the mating part and the docking part. In one embodiment of this utility model, the docking part is sleeved on the outside of the mating part, so as to realize the docking and fitting of the mating part and the docking part; in another embodiment of this utility model, the mating part is sleeved on the outside of the docking part, so as to realize the docking and fitting of the mating part and the docking part.

[0056] Specifically, in this embodiment, the mating part is sleeved onto the outside of the docking part.

[0057] Please see Figure 2-3 In a specific embodiment of this utility model, the water inlet 23 of the water tank 21 is configured as the mating part. The mounting base 22 has a first extension 25 protruding from one end facing the water tank 21. The first extension 25 at least partially extends into the water inlet 23 to form the mating part. The sealing structure 3 is disposed on the side surface of the first extension 25 and abuts against the inner wall of the water inlet 23. This configuration allows the water inlet 23 to be fitted onto the first extension 25, achieving a mating fit between the water inlet 23 and the first extension 25, thereby establishing communication between the mounting base 22 and the water tank 21. At this time, the sealing structure 3, disposed on the side surface of the first extension 25 and abuts against the inner wall of the water inlet 23, achieves an interference seal between the first extension 25 and the water inlet 23, thus ensuring a seal between the mounting base 22 and the water tank 21.

[0058] It is understood that, in this embodiment, in order to ensure the connection between the water supply port 23 and the water passage hole 24, the first extension 25 is arranged in a ring shape, so that the water in the water tank 21 can flow from the water supply port 23 through the inner ring of the first extension 25 into the water passage hole 24.

[0059] It should be noted that this utility model does not limit the specific form of the cooperation between the sealing structure 3 and the side surface of the first extension 25 when the sealing structure 3 is installed on the first extension 25. In one embodiment of this utility model, the sealing structure 3 is directly connected to the side surface of the first extension 25 so as to be sleeved on the side surface of the first extension 25, thereby realizing the connection between the sealing structure 3 and the first extension 25.

[0060] In another embodiment of this utility model, a mounting groove is recessed on the side surface of the first extension 25. The mounting groove is annular, and the opening of the mounting groove faces the side wall of the water supply port 23. Thus, the sealing structure 3 is disposed in the mounting groove to fit the mounting groove, thereby ensuring the installation stability of the sealing structure 3. The sealing structure 3 protrudes at least partially from the opening of the mounting groove so that this part can abut against the side wall of the water supply port 23 to achieve a seal between the first extension 25 and the water supply port 23.

[0061] In another embodiment of this utility model, the sealing groove can also be recessed on the side wall of the water supply port 23, and the sealing structure 3 is sleeved in the sealing groove. This arrangement can also ensure the installation stability of the sealing structure 3, thereby achieving a seal between the first extension 25 and the water supply port 23.

[0062] In other embodiments of this utility model, the connection and cooperation between the sealing structure 3 and the first extension 25 can also be selected in other forms. In actual installation, the appropriate form can be selected according to the requirements.

[0063] Please see Figure 4-5 In another specific embodiment of this utility model, the water passage hole 24 is configured as the mating part, and the end of the water tank 21 facing the mounting base 22 has a protruding second extension 26. The second extension 26 extends at least partially into the water passage hole 24 to form the mating part. The sealing structure 3 is disposed on the side surface of the second extension 26 and abuts against the hole wall of the water passage hole 24. With this configuration, the water passage hole 24 is sleeved on the second extension 26, realizing the mating fit between the water passage hole and the second extension 26, thereby realizing the communication between the mounting base 22 and the water tank 21. At this time, the sealing structure 3 is disposed on the side surface of the second extension 26 and abuts against the hole wall of the water passage hole 24, so as to realize the interference seal between the extension and the water passage hole 24. In this way, the sealing between the mounting base 22 and the water tank 21 can also be guaranteed.

[0064] Similarly, in this embodiment, the second extension 26 is also arranged in a ring shape to ensure the connection between the water supply port 23 and the water passage hole 24, so that the water in the water tank 21 can flow from the water supply port 23 through the inner ring of the first extension 25 into the water passage hole 24.

[0065] Of course, this utility model does not limit the specific cooperation form between the second extension 26 and the sealing structure 3 when the sealing structure 3 is installed on the second extension 26. In one embodiment of this utility model, the sealing structure 3 is directly sleeved on the side surface of the second extension 26 and abuts against the wall of the water passage hole 24, so as to achieve the connection between the sealing structure 3 and the first extension 25, and at the same time achieve the sealing between the second extension 26 and the water passage hole 24.

[0066] In another embodiment of this utility model, a mounting groove is recessed on the side surface of the second extension 26. The mounting groove is annular and the opening of the mounting groove faces the wall of the water passage hole 24. The sealing structure 3 is sleeved in the mounting groove to enhance the connection stability between the sealing structure 3 and the second extension 26. At the same time, the sealing structure 3 protrudes at least partially from the opening of the mounting groove to abut against the wall of the water passage hole 24, which can also achieve a seal between the second extension 26 and the water passage hole 24.

[0067] In another embodiment of this utility model, the mounting groove is recessed on the wall of the water passage hole 24, and the sealing structure 3 is sleeved in the mounting groove. This arrangement can also enhance the installation stability of the sealing structure 3, so that the part of the sealing structure 3 protruding from the groove opening of the mounting groove abuts and cooperates with the second extension 26, thereby ensuring the seal between the second extension 26 and the water passage hole 24.

[0068] Similarly, in other embodiments of this utility model, the sealing structure 3 and the second extension 26 can also be selected in other forms of cooperation, which can be selected according to the requirements in actual installation.

[0069] Furthermore, it should be noted that this utility model does not limit the specific sealing positions of the sealing element with the mating part and the connecting part. In another embodiment of this utility model, one end of the connecting part and one end of the mating part are mated and connected, and at least a portion of the sealing structure 3 is located between the mating and connecting end faces of the mating and connecting parts. In this embodiment, the mating and connecting parts are mated by their corresponding end faces approaching each other to achieve a mating connection, thereby realizing the communication between the mounting base 22 and the water tank 21. In this case, the sealing structure 3 is at least partially located between the two mating and connecting end faces of the mating and connecting parts, thus ensuring the sealing capability between the mating and connecting parts, thereby further ensuring the sealing performance between the mounting base 22 and the water tank 21.

[0070] It is understood that in this embodiment, since the mating part and the docking part are connected and fitted through two mating end faces, in order to ensure the communication between the water supply port 23 and the water passage hole 24, so that the water tank 21 can smoothly supply water to the steam generating chamber 1 and ensure the steam generating chamber 1 generates steam at a certain rate, one end face of the mating part and the docking part is provided with the water supply port 23, and the other end face is provided with the opening of the water passage hole 24. In this way, the communication between the water supply port 23 and the water passage hole 24 can be ensured while the docking part and the mating part are connected, and the sealing performance of the sealing structure 3 can be further guaranteed.

[0071] It is also understood that, in this embodiment, in order to enable the sealing structure 3 to form a seamless seal for the mating part, the connecting part, and the water passage hole 24, the sealing structure 3 is at least partially sleeved on the periphery of the water supply port 23 and the water passage hole 24 to ensure the sealing performance of the water supply port 23 and the water passage hole 24.

[0072] In a specific embodiment of this utility model, the mounting base 22 and the water tank 21 are respectively configured as the docking part and the mating part. At this time, the sealing structure 3 is entirely disposed between the two end faces of the mounting base 22 and the water tank 21 that mate with each other. When the mounting base 22 and the mating part are connected, they jointly clamp and squeeze the sealing structure 3, thereby achieving an interference fit with the sealing structure 3.

[0073] Please see Figure 6-7In another specific embodiment of this utility model, the mounting base 22 is configured as the docking part, the water tank 21 is configured as the mating part, and the sealing structure 3 has a first end and a second end arranged opposite to each other. The first end is connected to the water passage hole 24, and the second end extends from the opening of the water passage hole 24 to the space between the water tank 21 and the mounting base 22, so as to abut against the water tank 21 and the mounting base 22. With this configuration, the first end of the sealing structure 3 is connected to the water passage hole 24, thus ensuring the installation stability of the sealing structure 3. Simultaneously, the second end of the sealing structure 3 extends from the opening of the water passage hole 24 into the space between the mounting base 22 and the water tank 21. At this time, the mounting base 22 and the water tank 21 can jointly clamp and compress the second end, so that the second end completes the interference seal between the mounting base 22 and the water tank 21.

[0074] In another specific embodiment of this utility model, the water tank 21 is configured as the docking part, the mounting base 22 is configured as the mating part, and the sealing structure 3 has a first end and a second end arranged opposite to each other. The first end is connected to the water supply port 23, and the second end extends from the water supply port 23 to the space between the mounting base 22 and the water tank 21 to abut against the mounting base 22 and the water tank 21. With this configuration, the first end of the sealing structure 3 is connected to the water supply port 23, which also ensures the installation stability of the sealing structure 3. Simultaneously, the second end of the sealing structure 3 also extends from the water supply port 23 to the space between the mounting base 22 and the water tank 21, and abuts against the two corresponding end faces of the mounting base 22 and the water tank 21, thereby achieving an interference seal between the mounting base 22 and the water tank 21.

[0075] Specifically, in this embodiment, the first end of the structure is connected to the water passage 24.

[0076] To further improve the interference seal performance of the sealing structure 3 on the mounting base 22 and the water tank 21, in a further embodiment of this utility model, the second end is bent toward the first end. This arrangement can further improve the elasticity of the sealing structure 3, thereby improving the sealing reliability between the mounting base 22 and the water tank 21. At the same time, it increases the sealing area, giving the sealing structure 3 superior structural strength and deformation resistance, thus extending the service life of the sealing structure 3.

[0077] Furthermore, when the water tank 21 is in an independent state and is not installed on the mounting base 22, it is necessary to prevent the water in the water tank 21 from spilling out of the water supply port 23; and when the water tank 21 needs to be installed on the mounting base 22, in order to ensure that the water in the water tank 21 can be continuously supplied, it is necessary to keep the water supply port 23 unobstructed at all times. Therefore, in one embodiment of this utility model, the water supply port 23 of the water tank 21 is provided with a blocking part 27. The blocking part 27 has a blocking state of blocking the water supply port 23 and a connected state of opening the water supply port 23. The water passage hole 24 is provided with a contact part 28. The contact part 28 is used to drive the blocking part 27 to switch from the blocking state to the connected state when the water tank 21 is installed on the mounting base 22. The first end of the sealing structure 3 is provided between the contact part 28 and the hole wall of the water passage hole 24, and is connected to the contact part 28. The sealing structure 3 is provided with a through hole for water to pass through.

[0078] In this embodiment, when the water tank 21 is not installed on the mounting base 22, the sealing part 27 remains in the sealed state for a long time. At this time, the sealing part 27 continuously seals the water supply port 23 to prevent water in the water tank 21 from leaking out of the water supply port 23. When the water tank 21 is installed on the mounting base 22, the sealing part 27 can switch from the sealed state to the connected state under the drive of the contact part 28, and will remain in the connected state for a long time. At this time, the water supply port 23 is normally open so as to continuously supply water to the steam generating chamber 1.

[0079] Furthermore, when the contact portion 28 is provided inside the water passage hole 24, in order to further improve the installation stability of the sealing structure 3 inside the water passage hole 24, in this embodiment, the first end of the sealing structure 3 is connected to the contact portion 28. Thus, the first end is fixed by the double connection of the contact portion 28 and the water passage hole 24, so as to further ensure the installation stability of the sealing structure 3. Moreover, when the first end is simultaneously connected to the contact portion 28 and the water passage hole 24, in order to enable the water tank 21 to smoothly supply water to the steam generating chamber 1, the sealing structure 3 is also provided with a through hole for water passage.

[0080] Of course, in other embodiments of this utility model, the through hole can also be provided on the contact portion 28, so that the water passage function of the through hole can also be realized.

[0081] It should be noted that this utility model does not limit the specific structural form of the sealing part 27 and the contact part 28. In one embodiment of this utility model, the sealing part 27 can be configured as a sealing plate, which is disposed inside the water tank 21 and is elastically movable in the direction close to or away from the water supply port 23. The contact part 28 is configured as a push rod. With this configuration, the push rod can continuously push the sealing plate in the direction away from the water supply port 23 during the installation of the water tank 21 on the mounting base 22, so as to open the water supply port 23 and realize the connection of the water supply port 23.

[0082] In another embodiment of this utility model, the sealing part 27 can be configured as a sealing plate, which is located on the outside of the water tank 21 and is elastically movable in the direction of approaching or moving away from the water supply port 23. The sealing plate is made of metal, and the contact part 28 can also be configured as a magnetic part. With this configuration, the magnetic part can magnetically engage with the sealing plate during the installation of the water tank 21 on the mounting base 22 to magnetically attract the sealing plate, causing the sealing plate to move away from the water supply port 23. In this way, the water supply port 23 can also be opened, thereby realizing the connection of the water supply port 23.

[0083] Of course, in other embodiments of this utility model, the blocking part 27 and the contact part 28 can also be configured in other structural forms, and can be selected according to the requirements when actually setting them.

[0084] In a further embodiment of this utility model, the mounting base 22 and the water tank 21 can be configured as an integral part. In this case, the steam generator 100 does not need to be configured with the sealing part 27 and the contact part 28. The water supply port 23 is connected to the water passage hole 24 for a long time. In this case, the water tank 21 is also provided with a water inlet for adding water into the water tank 21 to increase the water storage capacity of the water tank 21.

[0085] Similarly, this utility model does not limit the specific form of the steam generating device 100. In one embodiment of this utility model, the steam generating device 100 includes a garment steamer; in another embodiment of this utility model, the steam generating device 100 includes a steam dishwasher; and in other embodiments of this utility model, the steam generating device 100 may also have other structural forms. In actual installation, it can be selected according to the requirements.

[0086] For example, in a specific embodiment of this utility model, the steam generating device 100 can also be configured as a heating humidifier. In this way, during the operation of the heating humidifier, the heating humidifier can generate steam and water mist simultaneously. When the steam generation rate of the heating humidifier is higher than the steam discharge rate, the air pressure in the humidification chamber of the heating humidifier will rise, which will cause the water in the humidification chamber to flow back. At this time, the sealing structure 3 can reduce or even prevent the water flowing back from the humidification chamber, thereby ensuring the normal operation of the heating humidifier.

[0087] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
