Description

Technical Field

[0001] The utility model belongs to a handheld ironing device, in particular to a pump-free steam ironing device. Background Art

[0002] Existing steam ironing devices, such as various handheld steam brushes, use a water pump to transport the water in the water tank to the vaporization device, which has high manufacturing costs. In addition, the water pump consumes electricity to transport the water, which reduces the endurance of the stored power supply for ironing devices that can be disconnected from an external power supply and work with their own stored power supply. The presence of the water pump increases the failure points of the product.

[0003] The traditional electric iron is not equipped with a water pump, but its handle is at the top of the product and the ironing base is at the bottom of the product. The water tank is located above the ironing base and supplies water to the vaporization device through the water outlet located at the front thereof. When the ironing base is upright, the water tank cannot supply water to the vaporization device. Therefore, this electric iron is only suitable for flat ironing, that is, ironing with the ironing surface in a horizontal state, and its usage is limited. Utility Model Content

[0004] The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the existing ironing devices that rely on water pumps to deliver water and cannot take into account both manufacturing costs and flexible ironing, and to provide a pumpless steam ironing device, aiming to give it a flexible ironing function under the premise of simplifying the product structure.

[0005] To achieve the above-mentioned purpose, the pumpless steam ironing device of the utility model comprises a body, a handle, a water tank, a vaporizing device and an ironing panel, and is characterized in that: the water tank is connected to the vaporizing device via a water delivery channel, when the ironing panel is upright or horizontal, the water delivery channel is lower than the water tank, and the water stored in the water supply tank flows into the vaporizing device through the water delivery channel, and the water delivery channel is provided with a valve, and the valve comprises a control part extending out of the body for opening or closing the valve.

[0006] In the pumpless steam ironing device, when the ironing panel is upright or horizontal, the water delivery channel is lower than the water tank, and the water in the water tank flows into the vaporization device through the water delivery channel, so that the ironing can be performed in various ironing postures such as hanging ironing and flat ironing, which is convenient to use. In addition, there is no need for water pump delivery, which reduces the control of the water pump and the pipeline for water pump delivery, reduces the manufacturing cost, and reduces the failure points of the product.

[0007] Preferably, the handle extends in the vertical direction, the body is located at the upper end of the handle, the water tank is located at the upper end of the vaporizer and at the upper part of the body and is separated from the handle at the upper and lower sides of the body, the ironing panel is located at the front end of the body, and the vaporizer is located inside the body. This structural layout makes it easy for the user to switch between the flat ironing posture and the hanging ironing posture by holding the handle with his hand, and ensures smooth water supply.

[0008] In order to add water conveniently, the water tank is detachably assembled on the fuselage, the water tank has a water outlet, the water delivery channel is arranged on the fuselage, and the upper end of the water delivery channel is detachably connected with the water outlet. Accordingly, the water tank can be conveniently removed from the fuselage to add water to the water tank.

[0009] In order to ensure smooth water delivery, the water delivery channel and the vaporization device are located at the front of the machine body, and the water outlet is located at the front bottom side of the water tank. With this structure, when the ironing panel is upright or horizontal, the water delivery channel is lower than the water tank, and the water stored in the water supply tank flows into the vaporization device through the water delivery channel.

[0010] In order to ensure that all the water stored in the water tank is transported to the vaporization device, the bottom of the water tank is inclined to guide the water stored in the water tank to flow to the water delivery channel.

[0011] In order to ensure smooth water delivery, the water tank is provided with air holes, and the positions of the air holes are arranged so that the air holes are located at a high position of the water tank when the ironing panel is upright or horizontal.

[0012] In order to close or open the water delivery channel, the valve includes a valve port, a valve plug and a valve stem. The valve port is arranged in the path of the water delivery channel. The valve plug is arranged on the valve stem and is located at the valve port. The valve stem is movably arranged on the body to block the valve port or open the valve port with the valve plug. The valve stem extends outside the body, and the control unit is arranged at the outer end of the valve stem. Accordingly, the water delivery channel can be closed or opened by controlling the movement of the valve stem.

[0013] In particular, the water delivery channel extends in the vertical direction, the valve port is a connecting cavity intersecting with the water delivery channel, the valve stem is arranged in the front-to-back direction, the valve plug is located at the front end of the valve stem, and the control part is arranged at the rear end of the valve stem. Accordingly, the control part avoids the hand holding the handle, avoids the hand holding the handle from operating incorrectly, and provides convenience for the user to operate with the other hand.

[0014] In order to adjust the water flow rate, the valve port has a throttling cavity deviating from the water delivery channel. In addition, since the throttling cavity deviates from the water delivery channel, it has a larger buffer space, which can alleviate the air pressure generated by the vaporization device when generating steam on the water flow in the water delivery channel, ensuring smooth water delivery.

[0015] In order to ensure smooth water delivery, the water tank has a water outlet connected to the water delivery channel, and the diameter of the water outlet is smaller than the diameter of the water delivery channel. Accordingly, the water stored in the water tank generates water pressure to offset the air pressure generated when the vaporization device generates steam, so that the water stored in the water tank flows smoothly to the vaporization device.

[0016] In order to reduce the number of failure points, a fixed component is arranged in the fuselage, and the water delivery channel is arranged on the fixed component, thereby reducing the number of pipeline connections and avoiding water leakage.

[0017] The utility model connects the water tank to the vaporization device through the water delivery channel. The water delivery channel, the water tank and the vaporization device are configured so that when the ironing panel is upright or horizontal, the water delivery channel is lower than the water tank, and the water stored in the water tank flows into the vaporization device through the water delivery channel. The ironing device can be used for ironing in various ironing postures such as hanging ironing and flat ironing, which is convenient to use. Moreover, the water delivery channel is opened or closed by the control part, and the water pump is not required for water delivery, which reduces the control of the water pump and the pipeline for water pump water delivery, reduces the manufacturing cost, and reduces the failure points of the product.

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The terms "including" and "having" and any variations thereof in the specification and claims of the present utility model are intended to cover non-exclusive inclusions. For example, a method or product comprising a series of technical features is not necessarily limited to those technical features clearly listed, but may also include other technical features that are not clearly listed and can be included in the method or product.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Among them, "upper" is opposite to "lower", and "front" is opposite to "back".

[0032] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0033] like Figure 1 , Figure 5 As shown, the pumpless steam ironing device includes a body 100 , a handle 200 , a water tank 300 , a vaporizing device 400 and an ironing panel 500 .

[0034] The handle 200 extends in the up-down direction. The body 100 is located at the upper end of the handle 200 and extends forward and backward. During manufacturing, the body and the handle can be connected as one, or they can be manufactured separately and then assembled together.

[0035] The ironing panel 500 is located at the front end of the body 100, and the ironing panel 500 is provided with a steam release hole. The rear side of the ironing panel 500 and the upper side of the body 100 form an installation position.

[0036] The vaporizer 400 is located at the front portion of the body 100 .

[0037] The water tank 300 is located at the upper part of the body 100 and is separated from the handle 200 at the upper and lower sides of the body 100. The water tank 30 is installed at the installation position, with the front end of the water tank 300 close to the ironing panel 500 and the rear end of the water tank 300 flush with the rear end of the body 100, so that the length of the water tank 300 is close to the length of the body 100. When the water tank is filled with water, the weight of the water can be evenly distributed relative to the length of the body (front and back direction), so that the center of gravity of the ironing device is not too offset when holding the handle, thereby increasing the burden of holding. The bottom 302 of the water tank 300 is inclined to guide the water stored in the water tank to flow to the water delivery channel. Figure 1 , Figure 5 As shown, the water tank 300 is provided with an air vent 303, and the air vent 303 is located at the upper rear end of the water tank 300. The position of the air vent is such that the air vent is located at a high position of the water tank when the ironing panel is vertical or horizontal. The water outlet 301 is located at the front bottom side of the water tank 300, so that the air vent 303 is separated from the water outlet 301 and is located at two extreme positions of the water tank. The water outlet is conducive to water discharge, and the air vent is conducive to ventilation. The air vent assists the water outlet to discharge water and prevents water leakage from the water outlet. The diameter of the water outlet is smaller than the diameter of the water delivery channel.

[0038] A fixing member 101 is disposed in the body 100, and the fixing member 101 is located at the rear side of the ironing panel 500 and above the vaporization device 400. A water delivery channel 102 extending in the up-down direction is provided on the fixing member 101, and the water delivery channel 102 is located at the front part of the body 100. The lower end of the water delivery channel 102 is fixedly connected to the water inlet of the vaporization device 400. The upper end of the water delivery channel 102 is detachably connected to the water outlet 301 of the water tank. Accordingly, the water tank is connected to the vaporization device via the water delivery channel to deliver water to the vaporization device. In addition, the water tank can be removed from the body to add water to the water tank.

[0039] In view of the aforementioned assembly relationship, the ironing panel 500 is as follows Figure 1 When it is upright (hanging position) or Figure 5 When shown in a horizontal position (lying flat), the water delivery channel 102 is lower than the water tank 300 , and the water stored in the water tank flows into the vaporization device 400 through the water delivery channel 102 .

[0040] The water delivery channel 102 is provided with a valve 103. The valve 103 includes a control part 108 extending out of the body for opening or closing the valve. When the valve is opened by the control part, the water delivery channel is opened, and the water tank delivers water to the vaporization device. When the valve is closed by the control part, the water delivery channel is closed, and the water tank does not deliver water to the vaporization device.

[0041] The valve 103 includes a valve port 104, a valve plug 106 and a valve stem 107. The valve port 104 is arranged in the path of the water delivery channel 102. The valve plug 106 is arranged on the valve stem 107 and is located at the valve port 104. The valve stem 107 is movably configured on the body to block the valve port or open the valve port with the valve plug. The valve stem 107 is arranged in the front-to-back direction and extends backward to the outside of the body 100, and the control part 108 is arranged at the rear end of the valve stem 107. The valve port 104 is a connecting cavity intersecting with the water delivery channel 102, and the valve port 104 has a throttling cavity 105 deviating from the water delivery channel 102. The valve plug 106 is located at the front end of the valve stem 107.

[0042] As mentioned above, no matter the ironing panel 500 is Figure 1 As shown upright (hang ironing position) or as Figure 5 In the horizontal position (lying flat), the water delivery channel 102 is lower than the water tank 300, and the water in the water tank flows into the vaporization device through the water delivery channel. In actual use, the ironing panel can also be placed at any angle between upright and horizontal. In addition, the valve stem 107 is moved forward and backward by the control unit 108 to open or close the water delivery channel. Figure 2 As shown, the valve plug 106 completely blocks the valve port 104, the water delivery channel 102 is closed, and the water tank does not deliver water to the vaporization device. Figure 2 In the state shown, the valve stem 107 is moved backward, and the valve plug 106 also moves backward, thereby opening the valve port 104 halfway to achieve Figure 3 In the state shown, the water delivery channel 102 is opened but throttled, delivering water at a smaller flow rate. Figure 3 In the state shown, the valve stem 107 is continuously moved backward, and the valve plug 106 moves backward accordingly, thereby fully opening the valve port 104 to achieve Figure 4 In the state shown, the water delivery channel 102 is fully opened, without throttling, and delivers water at a maximum flow rate.

[0043] As mentioned above, the ironing device does not need a water pump to deliver water, but relies on a valve to open or close the water delivery channel, which reduces the control of the water pump and the pipeline for the water pump to deliver water, reduces the manufacturing cost, and reduces the failure points of the product. Moreover, it can be ironed in a variety of ironing postures such as hanging ironing and flat ironing, which is convenient to use.

[0044] When ironing, the stored water in the water tank flows to the vaporization device through the water delivery channel, the vaporization device heats the water and vaporizes it into steam, and the steam is released through the steam release holes on the ironing panel for ironing.
