Abstract
Description
Technical Field
[0001] This invention pertains to clothing ironing technology, specifically relating to an ironing device with the function of removing and filtering limescale. Background Technology
[0002] Steam ironing equipment, such as irons, produces limescale during operation. Limescale deposits in the equipment, blockage of steam vents, and being carried by steam onto clothing can all negatively impact ironing.
[0003] Patent document CN104420152B discloses an ironing appliance including a filter for trapping scale particles transported by steam. It includes a steam generator connected to a steam output port via a steam distribution circuit. The steam distribution circuit includes at least one filter for trapping scale particles transported by the steam flow. The steam distribution circuit of the ironing appliance includes a scale recovery cavity with a scale discharge port, which is sealed by a removable plug accessible from the outside of the appliance. The filter can be removed from the appliance through the scale discharge port. In other words, the scale recovery cavity and filter of this ironing appliance are located outside the steam generator. Steam needs to detour through the steam generator to exit the steam output port via the steam distribution circuit. The steam is cooled as it flows through the filter, affecting the ironing effect. Furthermore, to extend the steam flow path through the filter, and because the filter has a small flow surface, the steam pressure decreases after passing through the filter, resulting in lower steam pressure exiting the steam output port, which also affects the ironing effect. Furthermore, since the scale recovery cavity and filter of the ironing equipment are located outside the steam generator, and in order to place the scale recovery cavity and filter inside the ironing equipment, the ironing equipment becomes larger and more complex in structure.
[0004] Patent document CN117396646A discloses an iron including a scale removal device that can be removably inserted into an evaporation chamber. The removal device includes an elongated oval member with a cross-section much smaller than the cross-section of the evaporation chamber, and this member is equipped with a mechanical removal element adapted to contact the surface of the evaporation chamber. This removes any scale residue formed on the lower surface while the removal device is being removed from and / or inserted into the evaporation chamber. However, because the mechanical removal element is adapted to contact the surface of the evaporation chamber, a portion of the evaporation chamber surface is blocked by the mechanical removal element, preventing water delivered to the evaporation chamber from dripping or splashing onto the entire surface, thus affecting the vaporization rate. Furthermore, the mechanical removal element has difficulty contacting all surfaces of the evaporation chamber, therefore only removing scale from localized areas accessible to the mechanical removal element. Therefore, removing scale formed on the lower surface simultaneously by removing and / or inserting the removal device from the evaporation chamber is limited and cumbersome. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies, such as poor ironing results due to the filter being located outside the steam generator, and the cumbersome operation of removing scale formed on the lower surface while removing and / or inserting a removal device from the evaporation chamber. It provides an ironing device with scale removal and filtration functions.
[0006] To achieve the above objectives, the present invention provides an ironing device with scale removal and filtration functions, comprising a connected vaporization chamber, a steam distribution circuit, and a steam output port. The vaporization chamber and the steam distribution circuit are both defined on the inner side of a peripheral wall extending upward from the base plate. A scale buildup assembly is provided within the vaporization chamber. The scale buildup assembly includes a scale-forming rod extending forward and backward and suspended within the vaporization chamber, and a filter located at the rear of the scale-forming rod. The front part of the scale-forming rod extends to the front of the vaporization chamber. An assembly channel for removing the scale buildup assembly from the vaporization chamber is provided at the rear of the peripheral wall.
[0007] When this ironing equipment is working, the vaporization chamber vaporizes the supplied water into pressurized steam. The steam then flows within the vaporization chamber, and the scale particles carried by the steam accumulate on the scale-forming rod. These particles are then filtered out by the filter, preventing them from flowing out of the steam outlet and adhering to the ironed clothing. When the flowing steam comes into contact with the scale-forming rod and filter, any unvaporized water droplets it carries are further vaporized upon impact, reducing the moisture content of the steam.
[0008] This ironing device incorporates a filter within the vaporization chamber to trap scale particles carried by the steam, rather than placing the filter outside the vaporization chamber. Furthermore, since both the vaporization chamber and the steam distribution circuit are defined within the peripheral wall, the steam from the vaporization chamber, when exiting to the steam outlet via the steam distribution circuit, does not need to detour outside the vaporization chamber but flows within the peripheral wall. This shortens the flow path, prevents cooling, and minimizes pressure loss after passing through the filter, ensuring the steam pressure output from the steam outlet and guaranteeing the ironing effect.
[0009] In this ironing device, the scale-collecting rod extends back and forth within the vaporization chamber and is suspended in the air, allowing the lower surface of the vaporization chamber to be completely exposed to receive dripping and splashing water and vaporize it, thereby increasing the vaporization speed.
[0010] Because the scale-forming rod of this ironing device is suspended in the vaporization chamber, its temperature will be slightly lower than the temperature of the lower surface of the vaporization chamber. In particular, the heat of the lower surface of the vaporization chamber will not be directly conducted to the scale-forming rod. When water drips or splashes onto the scale-forming rod, it will not explode and vaporize as it would when it drips or splashes onto the lower surface of the vaporization chamber, which is conducive to the accumulation of scale on the surface of the scale-forming rod.
[0011] In this ironing equipment, because the scale-collecting rod and filter of the scale-collecting component are located in the vaporization chamber, the scale-collecting rod and filter can be fully heated, causing the tiny water droplets that come with the steam flow to collide with the scale-collecting rod and filter screen and be vaporized again, reducing the moisture content in the steam.
[0012] This ironing equipment, because the descaling component is placed inside the vaporization chamber instead of outside the vaporization chamber, does not increase the size of the ironing equipment and has a simple and compact structure.
[0013] During operation, scale particles accumulate on the surfaces of the scale-collecting rod and filter as the steam flows. After use, users simply need to remove the scale-collecting components from the vaporization chamber to clean the accumulated scale particles. Because the scale removal is done outside the ironing device, it is easier to clean.
[0014] In a preferred embodiment, the self-assembly channel extends to the outside of the ironing device via a transition channel. A plug, accessible from the outside of the ironing device, is positioned at the rear end of the descaling assembly. This plug seals the assembly channel and / or the transition channel to prevent steam leakage from the assembly channel. The transition channel increases the distance between the assembly channel and the outside of the ironing device, effectively blocking heat conduction between the vaporization chamber and the outside of the ironing device.
[0015] In a preferred embodiment, the scaling rod includes a head at the front end and wings extending rearward from the head. The head has a concave water collection groove including a bottom surface, and at least one side of the wings has longitudinal ribs extending in a front-rear direction. The head has a large surface area and is close to the core area of vaporization in the vaporization chamber, which is conducive to the accumulation of scale particles. The water collection groove can collect the delivered water in a short time and preheat and divert the water, which is conducive to the vaporization of the water. The wings and longitudinal ribs increase the surface area of the scaling rod, which can fully contact the flowing steam and allow scale particles flowing with the steam to accumulate on the surface of the scaling rod. The longitudinal ribs also help to strengthen the scaling rod.
[0016] In a preferred embodiment, the vaporization chamber and steam distribution circuit are defined between the base plate and the vaporization cover. The vaporization cover is equipped with the water inlet of the vaporization chamber, and the head is located below the water inlet as a diversion section to divert the water flowing down from the water inlet. When water droplets delivered to the vaporization chamber fall onto the head, it facilitates both the diversion of the delivered water and the accumulation of scale. Moreover, when water droplets delivered to the vaporization chamber fall onto the head, they are briefly retained and preheated, thereby reducing the temperature difference between the water and the lower surface of the vaporization chamber, making the water easier to vaporize. Furthermore, the vaporized water contains fewer tiny water droplets, reducing the moisture content in the steam and improving steam quality.
[0017] In a preferred embodiment, the wing includes a front wing and a rear wing. The front wing has several transverse ribs intersecting the longitudinal ribs, forming a scale accumulation zone between adjacent transverse ribs. The rear wing has several longitudinal ribs. The transverse ribs increase the surface area and scale accumulation capacity of the scaling rod, and also promote the meandering flow of steam in the scale accumulation zone, allowing scale particles in the steam sufficient time to accumulate on the scaling rod. They also facilitate scale accumulation in any direction on the scaling rod, such as on the surface facing forward of the transverse ribs or on the surface facing backward of the transverse ribs. Furthermore, the transverse ribs also increase the strength and rigidity of the scaling rod.
[0018] In a preferred embodiment, through holes are distributed on the wing corresponding to the scale accumulation area. Steam on both sides of the wing can flow through the through holes due to the pressure difference, causing the steam to flow in a meandering manner in the scale accumulation area, allowing the scale particles in the steam sufficient time to accumulate on the scale rod. The through holes also reduce the weight of the scale rod.
[0019] In a preferred embodiment, the longitudinal and transverse ribs are distributed on both sides of the front wing, and the transverse ribs on both sides of the front wing are inclined in opposite or parallel directions. This further increases the strength and scale-accumulating capacity of the scale rod. The transverse ribs can increase steam turbulence, which is beneficial for the deposition of scale particles.
[0020] In a preferred embodiment, the bottom surface of the head is distributed with diversion holes, and the sidewall of the water collection tank is a perimeter extending upward from the bottom edge, with all or part of the perimeter having notches for diversion. The diversion holes and notches allow the scaling rod to have a large surface area for scale accumulation, and also facilitate the diversion of the delivered water to the lower surface of the vaporization chamber for full vaporization. The recess can prolong the water's residence time there for sufficient preheating, thereby reducing the temperature difference between the water and the lower surface of the vaporization chamber, making the water easier to vaporize, and the vaporized water contains fewer tiny water droplets, reducing the moisture in the steam and improving steam quality.
[0021] In a preferred embodiment, a filter is connected to the rear of the scaling rod, with the filter located on the outer or inner side of the rear of the scaling rod. This structure allows the filter and the scaling rod to overlap in the length direction, thereby reducing the overall length of the scaling assembly and achieving scaling while maintaining a compact structure.
[0022] In a preferred embodiment, the vaporization chamber includes a front steam chamber and a rear steam chamber that are connected to each other. The filter is located in the rear steam chamber, and the front inlet of the filter is connected to the front steam chamber. The front steam chamber is used to receive the delivered water and vaporize it into steam. When the steam flows through the filter into the rear steam chamber, it is blocked by the filter, which traps the scale particles flowing with the steam. Accordingly, all the steam from the front steam chamber can flow through the filter, thus intercepting and filtering all the scale particles in the steam.
[0023] In a preferred embodiment, curved electric heating tubes are arranged inside the base plate. Steam distribution channels are defined outside the heating tubes, while the front and rear steam chambers are defined inside the heating tubes. There are two steam distribution channels, located on opposite sides of the vaporization chamber and connected to the rear steam chamber via a branch port spanning the heating tubes. Accordingly, the heating tubes serve as the boundary between the steam distribution channels and the vaporization chambers, simultaneously supplying heat to both. This ensures proper steam distribution while maintaining appropriate temperatures in the vaporization chambers and steam distribution channels, allowing the vaporization chambers to maintain efficient vaporization capacity, and enabling the steam distribution channels to further heat and maintain its temperature before output.
[0024] In a preferred embodiment, an isolation wall extends upward from the base plate and is located on the inner side of the peripheral wall. The isolation wall has a connecting opening that connects to the front inlet of the filter. The front steam chamber is located inside the isolation wall and the connecting opening, and the rear steam chamber is located outside the isolation wall and the connecting opening. The isolation wall isolates the vaporization chamber from the steam distribution channel, preventing direct communication between them. This extends the flow path of steam between the base plate and the vaporization cover, ensuring sufficient heating and maintaining dryness. The connection between the connecting opening and the front inlet of the filter facilitates easy disassembly and installation of the filter.
[0025] In a preferred embodiment, the filter is detached from or attached to the scale-collecting rod. Detachment facilitates separating the filter from the scale-collecting rod to clean the accumulated scale, while attachment maintains the assembly relationship between the filter and the scale-collecting rod.
[0026] In a preferred embodiment, the filter is tubular with filter holes distributed on its wall. This allows all steam to enter the filter from the front inlet and exit through the filter holes in the wall, effectively trapping all scale particles carried by the steam.
[0027] In a preferred embodiment, filter holes are distributed on all four sides of the filter's walls. A flow space is maintained on the outer side of the filter's walls to allow the front-end steam chamber to connect to the steam distribution channel via the filter's inner side, the filter holes, and the flow space. This provides the filter with a large filtration area and flow capacity, enabling the smooth flow of steam through the filter while filtering scale particles, preventing a drop in steam pressure due to the presence of the filter.
[0028] In a preferred embodiment, to simplify the structure, the length of the fouling assembly is shortened to allow the mechanism assembly to be placed in the vaporization chamber. The rear end of the filter is closed, and the rear end of the fouling rod extends into the filter through the front inlet and connects to the rear end of the filter. The rear end of the filter is connected to a plug.
[0029] In a preferred embodiment, to facilitate the removal and installation of the fouling assembly, the filter and fouling rod are connected to a plug for removal together through the assembly channel from the vaporization chamber. The plug directly or indirectly seals the assembly channel. That is, the fouling assembly can be removed by taking the plug out of the assembly channel, and the fouling assembly is installed into the vaporization chamber by sealing the assembly channel with the plug.

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. "Upper" and "lower," "left" and "right," and "front" and "rear" are opposite directions.
[0034] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.
[0035] Figure 1 A complete ironing apparatus according to the present invention is shown, comprising a bottom unit 100 and a housing 200 mounted above the bottom unit. The housing 200 integrates a water tank 210, a handle 220, and an electrical wire (not shown) extending from a cable conduit 230. By connecting the electrical wire to an external power source, the ironing apparatus can be operated by the user as needed using electrical power. In this application, the aim is to improve the bottom unit for filtering limescale particles that flow with the steam during the operation of the ironing apparatus; therefore, the invention is described below by detailing the bottom unit.
[0036] like Figure 2-6 As shown, the bottom unit 100 includes a bottom plate 110, a vaporization cap 120, a transition channel 130, and a scale buildup assembly 180. A curved heating element 111 is embedded within the bottom plate 110 for heating the bottom plate. The bottom plate 110 has an upwardly extending peripheral wall 112, grooves adjacent to the peripheral wall located on the inner side of the peripheral wall, and recesses located on the inner side of the grooves. The vaporization cap 120 is sealed to the bottom plate 110, covering the grooves and recesses, forming a steam distribution circuit 102 at the corresponding groove location and a vaporization chamber 101 at the corresponding recess location. The steam distribution circuit 102 and the vaporization chamber 101 are separated by an isolation wall 114. Figure 2 As shown, steam output holes 103 are also distributed on the base plate 110. The outer end of the steam output hole 103 is exposed on the bottom surface of the base plate 110, and the inner end of the steam output hole 103 is exposed in the steam distribution circuit 102.
[0037] Given the above structure, Figure 2-6The bottom unit 100 shown is capable of vaporizing water into steam and guiding steam flow based on the vaporization chamber 101, steam distribution circuit 102, and steam outlet 103. Specifically, both the vaporization chamber 101 and the steam distribution circuit 102 are defined inside a peripheral wall 112 extending upward from the bottom plate 110. A scale buildup assembly 180 is provided within the vaporization chamber 101. The scale buildup assembly 180 includes a scale rod 170 extending forward and backward and suspended within the vaporization chamber, and a filter 140 located at the rear of the scale rod. The front of the scale rod 170 extends to the front of the vaporization chamber. An assembly channel 113 for removing the scale buildup assembly from the vaporization chamber is provided at the rear of the peripheral wall 112. Here, "inner side of the peripheral wall 112" refers to the area surrounded by the peripheral wall. To emphasize the position of the scale buildup assembly 180 within the vaporization chamber, Figure 5 The base plate 110 is represented by a dashed line, and the scale buildup assembly 180 is represented by a solid line.
[0038] When the ironing equipment is working, the vaporization chamber 101 vaporizes the delivered water into steam with a certain pressure. The steam then flows in the vaporization chamber. When the scale particles flowing with the steam pass through the scale-forming rod 170, they will accumulate on the scale-forming rod. When the scale particles flowing with the steam pass through the filter 140, they will be filtered by the filter, preventing the scale particles from flowing out of the steam outlet hole and adhering to the clothes being ironed. When the flowing steam comes into contact with the scale-forming rod and the filter, the tiny water droplets that are not vaporized will collide with the scale-forming rod and the filter and be further vaporized, reducing the moisture content in the steam.
[0039] This ironing device incorporates a filter within the vaporization chamber to trap scale particles carried by the steam, rather than placing the filter outside the vaporization chamber. Furthermore, since both the vaporization chamber and the steam distribution circuit are defined within the peripheral wall, the steam from the vaporization chamber, when exiting to the steam outlet via the steam distribution circuit, does not need to detour outside the vaporization chamber but flows within the peripheral wall. This shortens the flow path, prevents cooling, and minimizes pressure loss after passing through the filter, ensuring the steam pressure output from the steam outlet and guaranteeing the ironing effect.
[0040] In this ironing device, the scale-collecting rod extends back and forth within the vaporization chamber and is suspended in the air, allowing the lower surface of the vaporization chamber to be completely exposed to receive dripping and splashing water and vaporize it, thereby increasing the vaporization speed.
[0041] Because the scale-forming rod of this ironing device is suspended in the vaporization chamber, its temperature will be slightly lower than the temperature of the lower surface of the vaporization chamber. In particular, the heat of the lower surface of the vaporization chamber will not be directly conducted to the scale-forming rod. When water drips or splashes onto the scale-forming rod, it will not explode and vaporize as it would when it drips or splashes onto the lower surface of the vaporization chamber, which is conducive to the accumulation of scale on the surface of the scale-forming rod.
[0042] In this ironing equipment, because the scale-collecting rod and filter of the scale-collecting component are located in the vaporization chamber, the scale-collecting rod and filter can be fully heated, causing the tiny water droplets that come with the steam flow to collide with the scale-collecting rod and filter screen and be vaporized again, reducing the moisture content in the steam.
[0043] This ironing equipment, because the descaling component is placed inside the vaporization chamber instead of outside the vaporization chamber, does not increase the size of the ironing equipment and has a simple and compact structure.
[0044] During operation, scale particles accumulate on the surfaces of the scale-collecting rod and filter as the steam flows. After use, users simply need to remove the scale-collecting components from the vaporization chamber to clean the accumulated scale particles. Because the scale removal is done outside the ironing device, it is easier to clean.
[0045] The above structure represents the most basic embodiment of the ironing equipment. To further enhance the ironing equipment's functionality and effectiveness, the following technical means can be used to optimize the ironing equipment and obtain a better embodiment.
[0046] like Figure 4-5 As shown, in a preferred embodiment, a transition channel 130 extends from the self-assembly channel 113 to the outside of the ironing device. This transition channel 130 is fastened to the base plate by fasteners and docks with the assembly channel 113. Figure 7-9 , Figure 11-12 As shown, the rear end of the buildup assembly 180 is equipped with a plug 150 accessible from the outside of the ironing device. The plug 150 seals the assembly channel and / or transition channel to prevent steam from escaping from the assembly channel. The transition channel increases the distance between the assembly channel and the outside of the ironing device, effectively blocking heat conduction between the vaporization chamber and the outside of the ironing device.
[0047] like Figure 10-11 As shown, in a preferred embodiment, the scaling rod 170 includes a head 171 at the front end and a wing 172 extending rearward from the head. The head 171 has a concave water collection groove 1714 including a bottom surface 1711, and at least one side of the wing 172 is provided with a longitudinal rib 1723 extending in the front-rear direction. The head has a large surface area and is close to the core part of vaporization in the vaporization chamber, which is conducive to the accumulation of scale particles. The water collection groove can collect the delivered water in a short time and preheat and divert the water, which is conducive to the vaporization of the water. The wing and the longitudinal rib increase the surface area of the scaling rod, which can fully contact the flowing steam and allow scale particles flowing with the steam to accumulate on the surface of the scaling rod. The longitudinal rib also helps to strengthen the scaling rod.
[0048] like Figure 4-5As shown, in a preferred embodiment, the vaporization chamber 101 and the steam distribution circuit 102 are defined between the base plate 110 and the vaporization cover 120. The vaporization cover 120 is configured with the water inlet 121 of the vaporization chamber, and the head 171 is located below the water inlet 121 as a diversion section to divert the water flowing down from the water inlet. When the water droplets delivered to the vaporization chamber fall onto the head, it is beneficial for both diverting the delivered water and for the accumulation of scale. Moreover, when the water droplets delivered to the vaporization chamber fall onto the head, they will be briefly retained and preheated, thereby reducing the temperature difference between the water and the lower surface of the vaporization chamber, making the water easier to vaporize. Furthermore, the vaporized water contains fewer tiny water droplets, reducing the moisture in the steam and improving the steam quality.
[0049] like Figure 10-11 As shown, in a preferred embodiment, the wing 172 includes a front wing 1721 and a rear wing 1722. The front wing 1721 has several transverse ribs 1724 intersecting the longitudinal ribs 1723, and a scale accumulation zone 1725 is formed between adjacent transverse ribs 1724. The rear wing 1722 has one or more longitudinal ribs 1723. The transverse ribs can increase the surface area and scale accumulation capacity of the scaling rod, and can also promote the meandering flow of steam in the scale accumulation zone, allowing scale particles in the steam sufficient time to accumulate on the scaling rod. They also facilitate scale particle accumulation in any direction on the scaling rod, such as scale accumulation on the surface facing forward of the transverse ribs or scale accumulation on the surface facing backward of the transverse ribs. Furthermore, the transverse ribs can also increase the strength and rigidity of the scaling rod.
[0050] like Figure 10-11 As shown, in a preferred embodiment, through holes 1726 are distributed on the wing 172 corresponding to the scale accumulation area. Steam on both sides of the wing can flow through the through holes due to the pressure difference, causing the steam to flow in a meandering manner in the scale accumulation area, allowing the scale particles in the steam sufficient time to accumulate on the scale rod. The through holes can also reduce the weight of the scale rod. Furthermore, through holes are also distributed on other parts of the wing.
[0051] like Figure 10-11 As shown, in the preferred embodiment, longitudinal ribs 1723 and transverse ribs 1724 are distributed on both sides of the front wing 1721, and the transverse ribs on both sides of the front wing are inclined in opposite or parallel directions. This is to further increase the strength and scale-accumulating capacity of the scale rod. The transverse ribs can increase the turbulence of steam, which is beneficial to the deposition of scale particles.
[0052] like Figure 10-11As shown, in a preferred embodiment, the bottom surface 1711 of the head 171 has distribution diversion holes 1712, and the sidewall of the water collection tank 1714 is a perimeter 1713 extending upward from the edge of the bottom surface 1711. All or part of the perimeter 1713 is provided with notches 1715 for diversion. The diversion holes and notches allow the scaling rod to have a larger surface area for scale accumulation, and also facilitate the diversion of the delivered water to the lower surface of the vaporization chamber for sufficient vaporization. The recess can prolong the water's residence time and allow for sufficient preheating, thereby reducing the temperature difference between the water and the lower surface of the vaporization chamber, making the water easier to vaporize. Furthermore, the vaporized water contains fewer tiny water droplets, reducing the moisture content in the steam and improving steam quality.
[0053] like Figure 7 , Figure 12 As shown, in a preferred embodiment, a filter 140 is connected to the rear of the scaling rod 170, and the filter 140 is located on the outer or inner side of the rear of the scaling rod 170. This structure allows the filter and the scaling rod to overlap in the length direction, thereby reducing the overall length of the scaling assembly and achieving scaling while keeping the structure of the scaling assembly compact.
[0054] like Figure 4-5 As shown, in a preferred embodiment, the vaporization chamber 101 includes a front steam chamber 1011 and a rear steam chamber 1012 that are connected. A filter 140 is located in the rear steam chamber 1012, and its front inlet 142 is connected to the front steam chamber 1011. The front steam chamber 1011 receives the supplied water and vaporizes it into steam. When the steam flows through the filter 140 into the rear steam chamber 1012, it is blocked by the filter, preventing the flow of scale particles. Therefore, all steam from the front steam chamber can flow through the filter, effectively intercepting and filtering all scale particles in the steam.
[0055] like Figure 4-5 As shown, in a preferred embodiment, a curved electric heating tube 111 is arranged inside the base plate 110. A steam distribution channel 102 is defined outside the electric heating tube 111, while the front steam chamber 1011 and the rear steam chamber 1012 are both defined inside the electric heating tube 111. There are two steam distribution channels 102, located on opposite sides of the vaporization chamber and connected to the rear steam chamber 1012 via a branch port 106 spanning the electric heating tube 111. Accordingly, the electric heating tube serves as the boundary between the steam distribution channel and the vaporization chamber, simultaneously supplying heat to both. While rationally distributing the steam, it also maintains appropriate temperatures in the vaporization chamber and the steam distribution channel, ensuring the vaporization chamber maintains efficient vaporization capacity and allowing the steam to be further heated and kept warm before being output through the steam distribution channel.
[0056] like Figure 5As shown, in a preferred embodiment, an isolation wall 114 extends upward from the base plate 110 and is located inside the peripheral wall 112. The isolation wall 114 has a connecting port 105, which connects to the front inlet 142 of the filter 140. The front steam chamber 1011 is located inside the isolation wall 114 and the connecting port 104, and the rear steam chamber 1012 is located outside the isolation wall 114 and the connecting port 105. The isolation wall 114 isolates the vaporization chamber 101 from the steam distribution channel 102, allowing the vaporization chamber and the steam distribution channel to connect through the diversion port 106 instead of directly, thus extending the flow path of steam between the base plate and the vaporization cover to ensure sufficient heating and dryness. The connection between the connecting port and the front inlet of the filter facilitates the disassembly and installation of the filter.
[0057] like Figure 12 As shown, in a preferred embodiment, the filter 140 is detached from or fixed to the scale rod 170. Detachment facilitates separating the filter from the scale rod to clean the accumulated scale, while fixing them together maintains the assembly relationship between the filter and the scale rod.
[0058] like Figure 12 As shown, in a preferred embodiment, the filter 140 is tubular with filter holes 141 distributed on its wall. This allows all steam to enter the filter from the front inlet and exit through the filter holes on the wall, effectively trapping all scale particles carried by the steam.
[0059] like Figure 12 As shown, in a preferred embodiment, filter holes 141 are distributed around the perimeter of the filter 140. A flow space 104 is maintained on the outer side of the filter's perimeter to allow the front-end steam chamber 1011 to connect to the steam distribution channel 102 via the inner side of the filter 140, the filter holes 141, and the flow space 104. This provides the filter with a larger filtration area and flow capacity, enabling the smooth flow of steam through the filter while filtering scale particles, preventing a decrease in steam pressure due to the presence of the filter.
[0060] like Figure 12 As shown, in a preferred embodiment, in order to simplify the structure, the length of the scale buildup assembly 180 is shortened to allow the mechanism assembly to be placed in the vaporization chamber. The rear end of the filter 140 is closed, and the rear end of the scale buildup rod 170 extends into the filter 140 through the front inlet 142 of the filter and is connected to the rear end of the filter. The rear end of the filter is connected to the plug 150.
[0061] like Figure 12As shown, in a preferred embodiment, to facilitate the removal and installation of the scale buildup assembly, the filter 140 and scale buildup rod 170 are connected to the plug 150 for removal together through the assembly channel from the vaporization chamber. The plug directly or indirectly seals the assembly channel. That is, the scale buildup assembly can be removed by taking the plug out of the assembly channel, and the scale buildup assembly is installed into the vaporization chamber by sealing the assembly channel with the plug. Furthermore, a handle 160 is connected to the plug 150, and the handle 170 allows for the disassembly and reassembly of the connected plug 150 and scale buildup assembly 180.
