Description

Technical Field

[0001] The present invention relates to the technical field of household appliance accessories, and in particular to a heating device with explosion-proof and drip-proof properties. Background Art

[0002] Ironing tools are commonly used to smooth clothes and fabrics. There are many types of irons, including ordinary electric irons, temperature-adjustable electric irons, and steam spray electric irons.

[0003] Currently, some ironing tools in the prior art have a steam explosion function. That is, when ironing, the explosive steam generated during use can improve the ironing effect of clothes and fabrics to a certain extent. However, some ironing machines with an explosion function do not have an explosion protection function. Under certain conditions, they are easily triggered by mistake, which not only easily causes dripping, but also easily causes water to enter the soleplate through the explosion channel and damage the soleplate. Summary of the Invention

[0004] The invention provides a heating device with explosion-proof dripping prevention which can avoid dripping phenomenon and has good steam explosion effect.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A heating device with explosion-proof dripping prevention includes a heating device body and a valve body assembly, wherein the valve body assembly has an explosion channel; a deformation member is provided on the heating device body, and the deformation member is used to sense the heating temperature of the heating device body. When the temperature of the deformation member reaches the deformation temperature, the deformation member triggers the explosion channel in the valve body assembly to open.

[0007] The principle and advantage of this solution are: by using a deformable member to sense the heating temperature of the heating device body, explosive steam is triggered according to preset conditions. That is, only after the preheating temperature of the heating device body reaches a preset value, the deformable member can undergo the expected deformation due to heat, triggering the explosion channel in the valve body assembly to open, thereby ensuring that all water is converted into steam. At the same time, it also avoids the situation where the preheating temperature of the heating device body is insufficient and all water cannot be converted into steam, resulting in some water dripping out of the explosion channel, that is, avoiding the dripping phenomenon, which can easily make clothes wet, resulting in poor ironing effect.

[0008] Preferably, as an improvement, the deformable member is a metal member, and the deformable member includes a deformable body, and the deformable body is provided with a contact piece, and the contact piece is used to trigger the opening of the explosion channel in the valve body assembly.

[0009] Beneficial effect: The above technical solution is adopted to facilitate the movement of the contact piece through the thermal deformation of the deformable body, that is, the contact piece is helpful to expand the moving stroke of the thermal deformation of the deformable part to a certain extent, which helps to stably trigger the opening of the explosion channel in the valve body assembly.

[0010] Preferably, as an improvement, the valve body assembly includes a three-way valve, a valve cover is connected to the three-way valve, and a valve stem is movably provided between the three-way valve and the valve cover; one end of the valve stem extends outward from the outside of the valve cover and corresponds to the deformable part.

[0011] Beneficial effects: The above technical solution is adopted to facilitate the movement of the valve stem, and corresponding to the deformable part, it can ensure that the deformable part can normally trigger the explosion channel in the valve body assembly to open after being deformed by heat.

[0012] Preferably, as an improvement, the three-way valve has a water inlet channel and a water outlet channel, and the water inlet channel and the water outlet channel are connected; a sealing assembly is provided on the valve stem, and a chamber is formed between the sealing assembly and the three-way valve, and the position of the chamber changes with the movement of the valve stem; when the deformable part is in a natural state or the deformable part is not bent and deformed by heat, the explosion channel is not connected to the chamber; when the temperature of the deformable part reaches the deformation temperature, the deformable part causes the position of the chamber to move to be connected with the explosion channel.

[0013] Beneficial effect: The above technical solution makes it easy to change the position of the chamber by moving the valve stem, that is, to control whether the explosion channel is connected to the water inlet channel and the water outlet channel according to the actual situation, thereby avoiding false triggering of the explosion channel.

[0014] Preferably, as an improvement, the sealing assembly includes an upper sealing ring and a lower sealing ring, an upper groove and a lower groove are provided on the valve stem, the upper sealing ring is adapted to the upper groove, and the lower sealing ring is adapted to the lower groove.

[0015] Beneficial effect: By setting up a sealing assembly, and the sealing assembly including an upper sealing ring and a lower sealing ring, a chamber is formed between the upper sealing ring, the lower sealing ring and the three-way valve.

[0016] Preferably, as an improvement, the valve stem is provided with a limiting portion located inside the valve cover.

[0017] Beneficial effects: The above technical solution facilitates the installation of the valve stem, prevents the valve stem from falling off or slipping, and improves the stability of its connection relationship.

[0018] Preferably, as an improvement, a reset member is provided on the valve stem, and the reset member is used to maintain the tendency of driving the valve stem to move in a direction close to the deformable member.

[0019] Beneficial effect: The above technical solution facilitates the valve stem to gradually reset under the action of the reset member after the external force applied to it by the deformation member is lost.

[0020] Preferably, as an improvement, the valve cover is detachably connected to the three-way valve.

[0021] Beneficial effect: By detachably connecting the valve cover to the three-way valve, the installation and replacement of the valve cover are facilitated.

[0022] Preferably, as an improvement, a clamping groove is provided on the valve cover, and a clamping portion is provided on the three-way valve, and the clamping portion is adapted to the clamping groove.

[0023] Beneficial effect: The provision of the clamping groove and the clamping portion facilitates the clamping of the valve cover on the three-way valve, making installation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] This embodiment is basically as shown in the attached Figure 1 -Attached Figure 6As shown:

[0034] A heating device with explosion-proof dripping prevention includes a heating device body 100 and a valve body assembly 200, the valve body assembly 200 has an explosion channel 211; a deformation member 110 is provided on the heating device body 100, and the deformation member 110 is used to sense the heating temperature of the heating device body 100. When the temperature of the deformation member 110 reaches the deformation temperature, the deformation member 110 triggers the explosion channel 211 in the valve body assembly 200 to open.

[0035] Specifically, in this embodiment, the deformable member 110 is a metal member and includes a deformable body 111. The deformable body 111 is provided with a contact piece 112. The contact piece 112 is used to trigger the opening of the explosion channel 211 in the valve body assembly 200. Preferably, the deformable body 111 is disc-shaped, and the contact piece 112 is generally strip-shaped.

[0036] In the above technical solution, the valve body assembly 200 includes a three-way valve 210, to which a valve cover 220 is connected. A valve stem 230 is movably interposed between the three-way valve 210 and the valve cover 220. One end of the valve stem 230 extends outward from the valve cover 220 and corresponds to the deformable member 110. During actual installation, the valve body assembly 200 is located directly above the deformable member 110. That is, the lower end of the valve stem 230 extends outward from the valve cover 220 and the lower end of the valve stem 230 is located directly above the deformable member 110.

[0037] Furthermore, in this embodiment, the three-way valve 210 has a water inlet channel 212 and a water outlet channel 213 , and the water inlet channel 212 and the water outlet channel 213 are connected.

[0038] In order to facilitate the movement of the valve stem 230, thereby controlling whether the explosion channel 211 is connected with the water inlet channel 212 and the water outlet channel 213, that is, to avoid false triggering of the explosion channel 211, in this embodiment, a sealing assembly is provided on the valve stem 230, and a chamber 201 is formed between the sealing assembly and the three-way valve 210, and the position of the chamber 201 changes with the movement of the valve stem 230; when the deformable member 110 is in a natural state or the deformable member 110 is not bent and deformed by heat, the explosion channel 211 is not connected with the chamber 201; when the temperature of the deformable member 110 reaches the deformation temperature, the deformable member 110 causes the position of the chamber 201 to move to be connected with the explosion channel 211.

[0039] Specifically, in the above scheme, in order to facilitate the formation of the chamber 201, the sealing assembly includes an upper sealing ring 231 and a lower sealing ring 232, and the valve stem 230 is provided with an upper groove 233 and a lower groove 234. The upper sealing ring 231 is adapted to the upper groove 233, and the lower sealing ring 232 is adapted to the lower groove 234. The chamber 201 is formed between the upper sealing ring 231 and the lower sealing ring 232 and the three-way valve 210.

[0040] Furthermore, the valve stem 230 is provided with a limiting portion 235 located inside the valve cover 220. The limiting portion 235 facilitates the installation of the valve stem 230 and can also prevent the valve stem 230 from falling off or sliding, thereby improving the stability of its connection relationship.

[0041] In order to facilitate the gradual reset of the valve stem 230 after the external force applied to it by the deforming member 110 is lost, in this embodiment, a reset member 236 is provided on the valve stem 230, and the reset member 236 is used to maintain the tendency of driving the valve stem 230 to move toward the direction close to the deforming member 110.

[0042] In the above technical solution, the reset member 236 is a valve core spring. Specifically, the valve core spring is sleeved on the valve stem 230 and is located between the lower groove 234 and the limiting portion 235 .

[0043] Furthermore, the valve cover 220 is detachably connected to the three-way valve 210. By detachably connecting the valve cover 220 to the three-way valve 210, the installation and replacement of the valve cover 220 are facilitated.

[0044] Specifically, in the above technical solution, a clamping groove 221 is provided on the valve cover 220 , and a clamping portion 214 is provided on the three-way valve 210 , and the clamping portion 214 is matched with the clamping groove 221 .

[0045] It should be noted that: in the solution of this embodiment, there is also an explosion button (not shown in the figure), which is used to control the state of the heating device body 100 to open or close the spraying explosion steam, and this explosion button is the existing technology in this field and will not be elaborated in detail here.

[0046] It is worth mentioning that: by using the deformable member 110 to sense the heating temperature of the heating device body 100, the explosive steam is triggered according to the preset conditions, that is, only after the preheating temperature of the heating device body 100 reaches the preset value, the deformable member 110 can undergo the expected deformation due to the heat, triggering the explosion channel 211 in the valve body assembly 200 to open, thereby ensuring that all water is converted into steam. At the same time, it also avoids the situation where the preheating temperature of the heating device body 100 is not enough and all water cannot be converted into steam, and some water will drip out of the explosion channel 211, that is, avoiding the dripping phenomenon, which can easily make the clothes wet, resulting in poor ironing effect.

[0047] The specific implementation process of this embodiment is as follows:

[0048] During actual installation and use, the valve body assembly 200 is installed on a corresponding housing, or assembled and applied according to other requirements.

[0049] When the heating device body 100 is heated to a predetermined temperature, the contact piece 112 gradually moves upward, that is, moves toward the direction close to the valve body assembly 200, and gradually pushes the valve stem 230 upward during its movement. At this time, the explosion channel 211 is connected to the water inlet channel 212 and the water outlet channel 213. When the explosion button is used, the heating device body 100 sprays explosion steam. When the temperature of the heating device body 100 drops, the deformable member 110 gradually returns to its original position, that is, it is out of contact with the valve stem 230. The valve stem 230 returns to its original position under the action of the valve core spring. That is, the explosion channel 211 is not connected to the water inlet channel 212 and the water outlet channel 213. At this time, even if the explosion button is pressed, the heating device body 100 will not spray explosion steam, thereby improving the overall use effect of the steam explosion and helping to increase the service life of the heating device body 100.

[0050] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
