Description

Technical Field

[0001] This utility model relates to the field of hair straightener technology, and in particular to a water tank structure and a steam-type hair straightener having the same structure. Background Technology

[0002] A hair straightener, also called an electric straightener plate, uses an electric current to heat its heating element or wires, which then conducts the heat to aluminum or ceramic plates. With technological advancements and improved living standards, hair straighteners are increasingly widely used. A hair straightener typically consists of two plates, upper and lower, which are electrically heated to a certain temperature to process the hair. Currently, heating is generally used to straighten or curl the hair, forcibly deforming it under heat. However, this method has significant drawbacks: firstly, it can easily damage the hair, causing frizz or affecting hair quality; secondly, during the straightening process, the hair is in a heated state and cannot cool down quickly, causing the hot hair to stick to the skin, resulting in discomfort or even allergies.

[0003] To address the aforementioned issues, a steam straightener / perm has emerged on the market that offers good results and is gentle on hair. However, existing steam straighteners / perms suffer from poor water delivery. Due to significant angle changes during use and the consumption of steam, the water outlet in the internal water tank sometimes rises above the liquid surface, preventing the pump from pumping water into the water path and causing an interruption in steam supply. Since existing technologies lack a solution to this problem, we propose a water tank structure and a steam straightener incorporating this structure to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a water tank structure and a steam straightener with the same structure, which can effectively solve the aforementioned problems.

[0005] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A water tank structure is provided, including a water tank cover and a water tank bottom plate that fit together to form a tank body, and a partition layer disposed inside the tank body; the partition layer has a movable part that divides the inner cavity of the tank body into two independent and variable-volume sealed sub-cavities; when the volume of either sealed sub-cavity increases, the movable part moves toward the other sealed sub-cavity and relatively reduces its volume; at least one of the inner walls of the two sealed sub-cavities is provided with a pipe opening for fluid to pass through.

[0007] In the water tank structure of this utility model, one side of the sealing sub-cavity of the partition layer is an air chamber, and the other side of the sealing sub-cavity is a water storage chamber; the pipe port component is provided on the side wall of the water storage chamber.

[0008] The water tank structure of this utility model includes a partition layer that is a semi-open soft rubber cover structure. The partition layer covers the upper surface of the bottom plate of the water tank and surrounds it to form the water storage cavity. The outer side wall of the partition layer and the top cover of the water tank surround the air chamber. The pipe port component on the side wall of the water storage cavity is a water outlet valve and is located on the bottom plate of the water tank.

[0009] In the water tank structure of this utility model, the edge of the partition layer is provided with an outwardly extending horizontally. When assembled, the lower edge of the water tank cover presses the extension onto the bottom plate of the water tank, and the top of the partition layer forms the movable part.

[0010] In the water tank structure of this utility model, the upper surface edge of the water tank bottom plate is provided with an annular rib on the lower side of the extension, and the lower end surface of the water tank cover is provided with an annular groove corresponding to the annular rib. When assembled, the upper and lower surfaces of the extension abut against the bottom surface of the annular groove and the upper surface of the annular rib, respectively.

[0011] In the water tank structure of this utility model, the upper surface edge of the extension is provided with an annular protrusion, and the bottom surface of the annular groove is provided with an annular groove that matches the annular protrusion. When assembled, the annular rib presses the annular protrusion against the annular groove.

[0012] In the water tank structure of this utility model, the air nozzle is located on one end of the longitudinal side wall of the water tank cover and above the annular convex edge.

[0013] The water tank structure of this utility model includes a water outlet valve comprising a valve core rod arranged longitudinally, a water outlet through which the lower end of the valve core rod passes on the bottom plate of the water tank, and a sealing head for sealing the water outlet at the upper end of the valve core rod. The water outlet valve further includes an elastic abutment that presses the sealing head against the upper surface of the bottom plate of the water tank, and a bracket that provides downward support for the elastic abutment. The bracket is connected to the bottom plate of the water tank.

[0014] In the water tank structure of this utility model, the pipe opening component is provided through the side wall of the air chamber, and the pipe opening component is an air nozzle; the bottom plate of the water tank and the top cover of the water tank are both elongated, and the two pipe opening components are respectively located at both ends of the tank body.

[0015] In addition, this utility model also provides a steam hair straightener having the above-mentioned water tank structure.

[0016] The beneficial effects of this utility model are as follows:

[0017] The overall structure is simple and easy to use after installation in a hair straightener. Simply fill one of the two sealed sub-cavities with water and connect it to the water pump's suction end. Once the water pump starts, it can extract the water and supply it to the hair straightener's steam generating component. Since the water-filled sealed sub-cavity has only one outlet connected to the outside, the pressure difference between the inside and outside after water extraction causes the moving part to move synchronously with the shrinking water volume due to atmospheric pressure, thus reducing the volume of the sealed sub-cavity. This prevents the liquid from separating from the outlet and the sealed sub-cavity, ensuring a constant water supply to the water pump. Users will not experience intermittent steam output or complete lack of steam in any particular position, regardless of the hair straightener's orientation. This significantly improves the user experience and indirectly enhances the product's competitiveness. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The preferred embodiment of the water tank structure of this utility model is as follows: Figure 1-5As shown, the tank includes a water tank cover 10 and a water tank bottom plate 20 that fit together to form a tank body 100, and a partition layer 30 disposed within the tank body 100. The partition layer 30 has a movable part 31 that divides the inner cavity of the tank body into two independent and variable-volume sealed sub-cavities, while the total volume of the two sealed sub-cavities remains constant. When the volume of either sealed sub-cavity increases, the movable part 31 moves toward the other sealed sub-cavity, causing its volume to decrease relatively. At least one of the inner walls of the two sealed sub-cavities is provided with a pipe opening component for fluid passage, which is specifically disposed on the water tank cover 10 and / or the water tank bottom plate 20. Specifically, the pipe opening component can be provided in any one of the sealed sub-cavities, in which case the sealed sub-cavity with the pipe opening component is used for water storage. Alternatively, both sealed cavities can be provided with pipe opening components, in which case either sealed cavity can be selected for water storage, depending on actual needs. Different methods; This water tank structure is easy to use after being installed inside the straightener. Simply fill one of the two sealed sub-cavities with water and connect the water pump's suction end to its pipe component. When the water pump starts, it can draw out the water and supply it to the steam generating component of the straightener. Moreover, since the sealed sub-cavity filled with water only has one outlet connected to the outside, the pressure inside and outside is inconsistent after water is drawn. Therefore, during the water drawing process, the moving part 31 will move synchronously with the volume of water due to atmospheric pressure, which will reduce the volume of the sealed sub-cavity. This avoids the separation of the liquid from the outlet and the sealed sub-cavity, thus ensuring that the outlet always supplies water to the water pump. During use, no matter what position the straightener is in, there will be no situation where the steam output is intermittent after a period of use, or no steam output at all in a certain position. This greatly improves the user experience and can indirectly improve the product's competitiveness.

[0030] In this embodiment, preferably, one side of the sealing sub-cavity of the partition layer 30 is the air chamber 50, and the other side is the water storage chamber 60; the pipe port component on the side wall of the water storage chamber 60 is the water outlet valve 41, and only one sealing sub-cavity is provided with the pipe port component. In this way, when the water storage chamber 60 is connected to the water inlet of the straightener's water pump through the pipe port component, during the water pumping process, since the water storage chamber 60 is a sealed space and the movable part 31 is formed by its wall, as the liquid inside the water storage chamber 60 decreases, the outer side of the movable part 31 will be squeezed by atmospheric pressure, causing it to move and the volume of the water storage chamber 60 to decrease with the decrease of the stored water, thereby avoiding the space between the liquid inside the water storage chamber 60 and the water inlet of the pipe port component, which would lead to the interruption of steam supply.

[0031] In this embodiment, the partition layer 30 is a semi-open soft rubber cover structure, specifically made of silicone. The opening of the partition layer 30 faces downward and covers the upper surface of the water tank bottom plate 20, forming a water storage cavity 60. The outer wall of the partition layer 30 and the water tank top cover 10 form an air chamber 50. The pipe port component on the side wall of the water storage cavity is a water outlet valve 41, which is located on the water tank bottom plate 20. The water outlet valve 41 is located on the water tank bottom plate 20 and is used to connect to the water pump of the steam generator to supply it with the water required to generate steam. Specifically, the water outlet valve 41 can be any commonly used valve body on the market.

[0032] In this embodiment, the edge of the partition layer 30 is provided with an extension 32 extending outward horizontally along the circumferential direction. When assembled, the lower edge of the water tank cover 10 presses the extension 32 tightly onto the water tank bottom plate 20 to ensure the stability of the partition layer 30 and prevent it from displacing due to vibration and causing water leakage. Furthermore, the top of the partition layer 30 forms a movable part 31. When the liquid in the water tank decreases, the top of the partition layer 30 also collapses, reducing its internal space, thereby ensuring that its changing internal cavity is filled with water needed to generate steam and maintaining the water supply to the water pump.

[0033] In this embodiment, the upper surface edge of the water tank bottom plate 20 is provided with an annular rib 70 adapted to the lower circumferential side of the extension 32. The lower end surface of the water tank cover 10 is provided with an annular groove 80 for the purpose of adapting to the annular rib 70. When assembled, the upper and lower surfaces of the extension 32 abut against the bottom surface of the annular groove 80 and the upper surface of the annular rib 70, respectively, to further improve the sealing performance of the inner cavity of the partition layer 30 and further reduce the risk of leakage.

[0034] In this embodiment, the upper surface edge of the extension 32 is provided with an annular protrusion 310, and the bottom surface of the annular groove 80 is provided with an annular groove 81 that matches the annular protrusion. When assembled, the annular rib 70 presses the annular protrusion 310 against the annular groove. Through the cooperation of the annular groove 81 and the annular protrusion 310, the edge of the partition layer 30 can be effectively prevented from being pulled off by the deformation force towards the center when it shrinks. This ensures that the partition layer 30 can be laid flat on the bottom plate 20 of the water tank after shrinkage and deformation, so as to further squeeze more liquid into the pipe component.

[0035] In this embodiment, the air nozzle 42 is located on one end of the longitudinal sidewall of the water tank cover 10 and above the annular protrusion 310, so as to avoid affecting the sealing stability of the edge of the separator 30.

[0036] In this embodiment, specifically, the outlet valve 41 includes a valve core rod 411 that is longitudinally movable. The water tank bottom plate 20 has an outlet 201 through which the lower end of the valve core rod 411 passes. The upper end of the valve core rod 411 has a sealing head 90 that seals the outlet 201. Specifically, the sealing head 90 is a circular ring integrally connected to the valve core rod 411 coaxially. A cone 100 with its larger end facing upwards is integrally and coaxially provided on the upper side wall of the valve core rod 411. The upper end of the cone 100 is integrally connected to the lower surface of the circular ring. Furthermore, to further ensure sealing, a frustum-shaped sealing ring 140 is coaxially fitted below the cone 100. When assembled, the cone 100 presses the sealing ring against the inner wall of the outlet. Furthermore, the outlet valve 41 also includes an elastic abutment 412 that presses the sealing head 90 against the upper surface of the water tank bottom plate 20, and a bracket 413 that provides downward support for the elastic abutment 412; the bracket 413 is connected to the water tank bottom plate 20, which can be a detachable connection or a fixed connection; wherein, the elastic abutment 412 is a spring, torsion spring, C-shaped spring, or elastic rubber block, etc., preferably, this embodiment uses a spring, and has a positioning groove for positioning spring on the upper end surface of the valve core rod 411, while the bracket 413 is cylindrical and covers the sealing head 90 on the water tank bottom plate 20, and in order to ensure the flow of liquid, the side wall of the bracket 413 is hollowed out.

[0037] Furthermore, an annular weir 110 surrounding the outlet 201 is provided on the lower surface of the water tank bottom plate 20 to facilitate the connection pipe of the water pump of the positioning straightener with the valve core rod 411.

[0038] In addition, a water inlet 120 is provided on the bottom plate of the water tank to facilitate users to add water. The water inlet 120 is equipped with a sealing plug 130 for sealing purposes.

[0039] Example 2

[0040] This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a pipe component, which is an air nozzle 42, is also provided through the side wall of the air chamber 50. The water tank bottom plate 20 and the water tank top cover 10 are both elongated, and the two pipe components are located at the two ends of the tank respectively. In this embodiment, the water outlet of the straightener can be connected to the air nozzle, while the water outlet valve on the water tank bottom plate 20 is directly connected to the steam generating component of the straightener. When working, the water pump is used as an air pump and fills the space between the partition layer 30 and the water tank top cover 10 with air to generate positive air pressure. This allows the partition layer 30 to move towards the water tank bottom plate 20 and fit together, thereby squeezing out the liquid in the water storage chamber 60 to continuously supply the required water to the steam generating component.
