[0040] The utility model will be further described in conjunction with the drawings and specific embodiments.

[0041] Embodiment one

[0042] Reference Figures 1 to 12 As shown in the figure, the embodiment provides a mute and multi-angle ironing steam brush, which comprises a shell 20 and a heating disc group 1 assembled on the shell 20, the heating disc group 1 has an ironing plate 13 exposed to the shell 20, the shell 20 has a handle 203, for the convenience of description, referring to the attached Figure 1 and Figure 3 As shown in the figure, the ironing plate 13 is exposed to the lower side of the shell 20, and the handle 203 is located at the back side of the shell 20. Among them, the shell 20 also has a water storage tank 201, which is located on the side of the heating disc group 1 away from the ironing plate 13, that is, the attached Figure 1 and Figure 3 The water storage tank 201 is located on the upper side of the heating disc group 1. The water storage tank 201 has a water outlet 202, and the water outlet 202 of the water storage tank 201 is connected with the water inlet 111 of the heating disc group 1 through the water passage 204, and the water outlet 202 of the water storage tank 201, the water passage 204 and the water inlet 111 of the heating disc group 1 are all located on the side facing the handle 203, that is, the attached Figure 1 and Figure 3 They are all arranged on the back side of the shell 20.

[0043] The water storage tank 201 is directly formed on the housing 20 of the steam brush, and the water outlet 202 and the water passing channel 204 of the water storage tank 201 and the water inlet 111 of the heating disc group 1 are all arranged on the side facing the handle 203; thus, in the use state, the ironing plate 13 is downwardly ironed (as shown in Figure 1 and Figure 3 ) and the steam brush is held up to make the handle 203 downward (as shown in Figure 5 and Figure 6 ) or at a plurality of horizontal angles, the water in the water storage tank 201 can be output to the heating disc group 1, and the supply of liquid water is realized. When the clothes are placed on the desktop for ironing, the ironing plate 13 is downwardly ironed, as shown in Figure 1 and Figure 3 , the water storage tank 201 is located on the upper side of the heating disc group 1, and the water in the water storage tank 201 can be normally output to the heating disc group 1; when the steam brush is held up for ironing, the handle 203 is generally downward, at this time, as shown in Figure 5 and Figure 6 , the water outlet 202 and the water passing channel 204 of the water storage tank 201 and the water inlet 111 of the heating disc group 1 are all at the low position, and the water in the water storage tank 201 can still be normally output to the heating disc group 1, and the normal supply of liquid water is realized. Further, the structure design of the present application can realize effective steam output and achieve better ironing operation when the steam brush is held up and the handle 203 is inclined at any direction on the basis of being downward, even when the handle 203 is horizontal or inclined upward at a certain angle (such as about 10° upward), the effective supply of liquid water can be realized, and the heating disc group 1 can realize effective steam output.

[0044] The structure design of the present application does not need to use the water pump structure in the prior art, so that the structure is simplified, the operation is quiet, and the effect of multi-angle ironing is met.

[0045] Further preferably, as shown in Figure 1 and Figure 3 , the water outlet 202 of the water storage tank 201 is arranged at the lower side of the rear of the water storage tank 201, so that the water in the water storage tank 201 can be fully output in the flat use state.

[0046] Meanwhile, the water passage 204 is equipped with a switch valve 30, which is used to output water from the water storage tank 201. Specifically, the switching valve 30 is a manually controlled switching valve, more specifically a push-button type switching valve, including a valve seat 31, a valve stem 32, an elastic reset element 34, and a self-locking push cap 33. The valve seat 31 has a valve cavity 311 and a valve cavity inlet 312 and a valve cavity outlet 313 communicating with the valve cavity 311. The valve stem 32 passes through the valve cavity outlet 313 of the valve seat 31 and forms a sealing fit with the valve cavity outlet 313. Specifically, the valve stem 32 is vertically arranged and has a clearance notch 321. The push cap 33 connects to the end of the valve stem 32 and is exposed outside the housing 20, specifically on the upper surface of the water storage tank 201. The first press of the push cap 33 drives the valve stem 32 to move until its clearance notch 321 is located inside the valve cavity outlet 313 and self-locks, thereby opening the valve cavity outlet 313; this state is as follows. Figure 4 As shown. The elastic reset member 34 applies an upward elastic force to the valve stem 32. The second press of the pressing cap 33 releases the self-locking mechanism and, under the action of the elastic reset member 34, drives the valve stem 32 back to the position blocking the valve cavity outlet 313. Specifically, the elastic reset member 34 is a spring, which is sleeved on the valve stem 32, with its upper end abutting against the pressing cap 33 and its lower end abutting against the valve seat 31. When water needs to be output, press the press cap 33 to drive the valve stem 32 downward, so that the clearance notch 321 of the valve stem 32 is located in the valve cavity outlet 313 to open the valve cavity outlet 313. At this time, the press cap 33 is self-locking, allowing water from the water storage tank 201 to be output normally to the heating plate assembly 1. When not in use, press the press cap 33 again to release the self-locking of the press cap 33. The elastic reset member 34 drives the valve stem 32 upward to reset, so that the valve stem 32 re-seals the valve cavity outlet 313, and the water passage 204 is blocked. This manual control method allows for further simplification of the structure. Specifically, the self-locking press cap 33 is an existing structure, which can be referred to as the pen cap structure used in telescopic ballpoint pens, etc., and will not be described in detail here.

[0047] The shell 20 comprises a base 21, a partition 23, an upper cover 22 and a handle cover 24, the upper cover 22 is covered on the base 21, the partition 23 is arranged between the upper cover 22 and the base 21, and the partition 23 and the upper cover 22 jointly constitute the water storage tank 201, the base 21 is integrally formed with a handle base 211, the handle cover 24 is covered on the handle base 211 and jointly constitutes the handle 203, and the heating disc group 1 is fixed at the bottom of the base 21; in this way, the specific arrangement of the shell 20 is realized, and the structural layout is simple. Of course, in other embodiments, the specific structure of the shell 20 is not limited to this, but can also be assembled by more components, for example, the handle base 211 can also be a separate component, which is connected to the base 21 by assembling and fixing after cooperating with the handle cover 24.

[0048] Specifically, the upper cover 22 constituting the water storage tank 201 is also provided with a water inlet 221, which is convenient for supplementing water, and the water inlet 221 is covered with a sealing cover 222, which is opened when water needs to be added, and is closed after water is added.

[0049] The heating disc group 1 is also hinged with a disc clamp 40, the disc clamp 40 cooperates with the ironing plate 13 to constitute a clamp ironing structure, so as to clamp clothes on one side of the ironing plate 13, thereby facilitating ironing of clothes hung on a clothes hanger without support. The shell 20 is also provided with a disc clamp driving assembly 41 for driving the disc clamp 40 to open and close, which is convenient for the operator to use.

[0050] Further preferably, since the steam brush needs to be used at multiple angles, in order to ensure that the heating disc group 1 can heat water enough to achieve the effect of stable steam output, in the embodiment, the heating disc group 1 is designed as a double-layer electric heating disc 100; as shown in detail in Figures 7 to 12 The double-layer electric heating disc 100 comprises an electric heating disc body 10, the electric heating disc body 10 has a first heating layer 101 and a second heating layer 102 arranged oppositely; wherein the first heating layer 101 and the second heating layer 102 are respectively provided with two channel units 17, specifically, the first heating layer 101 has two channel units 17, as shown in Figure 11 The first channel unit 171 and the third channel unit 173, the second heating layer 102 has two channel units 17, as shown in Figure 12 The second channel unit 172 and the fourth channel unit 174. The electric heating disc body 10 is provided with three through holes 18, which are a first through hole 181, a second through hole 182 and a third through hole 183.

[0051] The channel units 17 of the first heating layer 101 and the channel units 17 of the second heating layer 102 are connected in an alternating manner through the three through openings 18, thereby obtaining a heating channel that is arranged in a back-and-forth manner between the first heating layer 101 and the second heating layer 102. Specifically, the leading end of the first channel unit 171 (i.e., the leading end of the heating channel) is connected to the water inlet 111 on the heating disc group 1, the water inlet 111 is formed on the electric heating disc body 10, the first through opening 181 connects the trailing end of the first channel unit 171 and the leading end of the second channel unit 172, the second through opening 182 connects the trailing end of the second channel unit 172 and the leading end of the third channel unit 173, the third through opening 183 connects the trailing end of the third channel unit 173 and the leading end of the fourth channel unit 174, and the fourth channel unit 174 serves as the trailing end of the heating channel and is connected to the steam outlet 131.

[0052] In use, liquid water flows into the first channel unit 171 of the first heating layer 101 from the water inlet 111, and then sequentially flows through the first through opening 181, the second channel unit 172, the second through opening 182, the third channel unit 173, the third through opening 183, and the fourth channel unit 174. Figure 11 and Figure 12 In the process, the liquid water is continuously heated in each channel unit 17 of the first heating layer 101 and the second heating layer 102 until it is vaporized into high-temperature steam, and the high-temperature steam is finally sprayed out from the steam outlet 131.

[0053] The first heating layer 101 and the second heating layer 102 are provided with at least two channel units 17 and form a heating channel arranged in a back-and-forth manner, thereby increasing the number of channels while keeping the area of the heating layer unchanged, i.e., shortening the length of each channel. In use, as the steam brush switches between different orientations, such as switching from a horizontal state to an inclined state, water will flow downward and accumulate in the lower part of the channel unit 17. As the water inlet 111 continuously supplies water, the current channel unit 17 can be filled with water in a short time and quickly enter the next channel unit 17 through the corresponding through opening 18, thereby shortening the time of water stagnation, i.e., the water in each channel unit 17 can be timely output to the next channel unit 17, and the liquid water flows back and forth between the first heating layer 101 and the second heating layer 102 quickly, thereby achieving more sufficient and uniform heating. The liquid water is heated and vaporized in a timely manner to ensure continuous output of steam and prevent water from dripping when the steam brush is used at full angle.

[0054] Specifically, in this embodiment, the number of steam outlets 131 is multiple, and the steam outlets 131 are distributed at intervals along the extension direction of the fourth channel unit 174 to meet the requirements of the amount and area of the sprayed steam.

[0055] The electric hot plate body 10 comprises an upper cover plate 11, a heating shell 12, the ironing plate 13 and the heater 14, the heating shell 12 has a first heating groove arranged on its upper surface and a second heating groove arranged on its lower surface, the upper cover plate 11 covers the upper surface of the heating shell 12 and forms a first heating layer 101 together with the first heating groove, the water inlet 111 is arranged on the upper cover plate 11; the ironing plate 13 covers the lower surface of the heating shell 12 and forms a second heating layer 102 together with the second heating groove, the steam outlet 131 is arranged on the ironing plate 13, and the heater 14 is arranged in the heating shell 12. In this way, the structural design of the electric hot plate body 10 is realized.

[0056] Specifically, the heater 14 is a U-shaped heating tube composed of two opposite heating straight sections 141 and a heating curved section 142 connecting the two heating straight sections 141, the heating curved section 142 of the heater 14 corresponds to the front side of the heating shell 12, and the two heating straight sections 141 of the heater 14 correspond to the left and right sides of the heating shell 12 respectively, and the two end portions of the heater 14 are exposed to the rear side of the heating shell 12 for external wiring.

[0057] Specifically, the groove bottom surfaces of the first heating groove and the second heating groove of the heating shell 12 are covered with protruding convex portions 15, so that the heating area can be effectively increased and the heating is more efficient.

[0058] The water inlet 111 is arranged corresponding to the heater 14, specifically, the water inlet 111 is arranged corresponding to the heating curved section 142 of the heater 14, and at least a channel unit 17 (i.e. a first channel unit 171) connected with the water inlet 111 is arranged extending along the arrangement direction of the heater 14. The water inlet 111 corresponds to the front side of the heating shell 12, the first channel unit 171 has a first end located at the front side of the heating shell 12, and the first channel unit 171 extends along one side of the heating shell 12 to a position at the rear side of the heating shell 12, as shown by the line a in Figure 11 Further, a second channel unit 172 connected with the first channel unit 171 is also arranged extending along the arrangement direction of the heater 14, the second channel unit 172 extends from one side from back to front and then from another side from front to back in the layout of the second heating layer 102, forming a U-shaped channel corresponding to the heater 14, as shown by the line b in Figure 12

[0059] ​In order to further make full use of space and improve heating efficiency, the third channel unit 173 also extends along the arrangement direction of the heater 14; specifically, the third channel unit 173 is also mainly distributed on the other outer side of the heating shell 12 in the first heating layer 101; in this way, liquid water can be efficiently heated, and the heat source is fully utilized, and the vaporization efficiency is high.

[0060] Specifically, a plurality of the through holes 18 are arranged on the same side; in this embodiment, the first through hole 181, the second through hole 182, and the third through hole 183 are all arranged on the rear side of the heating shell 12; this arrangement is because, in use, due to the hand-held posture, water is more likely to accumulate on the rear side of the heating shell 12, and if it accumulates in this position, it can quickly enter another channel for heating due to the presence of the through hole. In addition, there is no heater 14 blocking the rear side of the heating shell 12, and the through hole 18 can be formed well.

[0061] The plurality of through holes 18 are away from the water inlet 111 of the electric heating disc body 10; in this embodiment, the water inlet 111 corresponds to the front side of the heating shell 12, and the plurality of through holes 18 are arranged on the rear side of the heating shell 12; the temperature of the water just entering from the water inlet 111 is low, and the plurality of through holes 18 are arranged away from the water inlet 111, on the one hand, to avoid the water entering from the water inlet 111 not making full use of the heat of the heater at the front end of the heating shell 12; on the other hand, the water flowing through the through hole 18 has basically reached a high temperature state, avoiding the influence of the low temperature near the water inlet 111 on the temperature at the position of the through hole 18, and further affecting the vaporization.

[0062] Specifically, the channel side wall of each channel unit 17 extends to the inside of the channel without a blocking wall 16; in this way, in a limited channel length, the transmission distance can be further extended, and the heating is more sufficient.

[0063] The electric heating disc body 10 is also provided with a temperature sensor for sensing the heating temperature of the electric heating disc body 10, so as to control the working of the heater 14; specifically, the temperature signal sensed by the temperature sensor is transmitted to an external controller, and the controller controls the working of the heater 14 according to the actual detected temperature; the control principle belongs to the prior art, and will not be described in detail.

[0064] The temperature sensor is close to the water inlet 111 of the electric heating disc body 10; in this way, it is used to detect the lower temperature area in the electric heating disc body 10, which can well guarantee the continuous heating of the lower temperature area, and further guarantee the overall heating.

[0065] Further, the electric heating disc body 10 is provided with a mounting groove 1171 at the middle position of the first heating layer 101, the temperature sensor is filled in the mounting groove 1171, so as to realize the assembly of the temperature sensor and the temperature sensor can directly and accurately detect the temperature of the heating disc body. Specifically, the mounting groove 1171 is formed in the heating shell 12 and exposed to the upper cover plate 11, facilitating the assembly operation, and the steam in the electric heating disc body 10 can be effectively prevented from penetrating into the mounting groove 1171.

[0066] Embodiment two

[0067] The steam brush provided by the embodiment is silent and can be ironed at multiple angles, and the structure is substantially the same as that of the embodiment one, except that the structure of the double-layer electric heating disc is adjusted. In the embodiment, the first heating layer 101 is provided with two channel units 17, and the second heating layer 102 is provided with three channel units 17. Specifically, the number of the through holes 18 is four, the two channel units 17 of the first heating layer 101 and the three channel units 17 of the second heating layer 102 are connected in an alternating manner through the four through holes 18, and then the heating channel is obtained, which is arranged back and forth between the first heating layer 101 and the second heating layer 102. The head end and the tail end of the heating channel are both in the second heating layer 102. The water inlet 111 and the steam outlet 131 are connected to the head end and the tail end of the heating channel respectively.

[0068] Meanwhile, the heating device 14 includes a plurality of independent heating pipes, and the plurality of heating pipes are uniformly distributed in the heating shell 12. The same effect can also be achieved.

[0069] The above-mentioned embodiment one and embodiment two respectively disclose two preferred embodiments in the present scheme, and of course, in other embodiments, it is not limited thereto. For example, the number of the channel units 17 of the first heating layer 101 or the number of the channel units 17 of the second heating layer 102 can also be three or more than three. As long as the channel units 17 of the first heating layer 101 and the channel units 17 of the second heating layer 102 are connected in an alternating manner to obtain the heating channel arranged back and forth between the first heating layer 101 and the second heating layer 102. In the plurality of through holes 18, the distribution position is not limited, such as can also be distributed on the left and right sides. The arrangement shape of each channel unit 17 is not limited and can be designed according to the actual situation. The structure of the electric heating disc body 10 can also be assembled by using more structure components.

[0070] Embodiment three

[0071] The steam brush provided by the embodiment is silent and can be used for multi-angle ironing, and has the same structure as the steam brush of the first embodiment, except that the heating disc group 1 in the embodiment does not use the double-layer electric heating disc 100, but uses other electric heating discs such as a single-layer heating electric heating disc. When the single-layer heating electric heating disc is used, there is only one heating channel, that is, the water directly flows from the water inlet 111 of the heating disc group 1 to the steam outlet 131 of the ironing plate 13. In this case, the water inlet 111 of the heating disc group 1 is located between the steam outlet 131 and the handle 203 when projected onto the projection plane where the ironing plate 13 is located. In this way, when the steam brush is held for use, the steam outlet 131 is higher than the water inlet 111 of the heating disc group 1. In this way, the water input by the water inlet 111 of the heating disc group 1 can be accumulated at the bottom and be sufficiently heated and vaporized by the heating disc group 1, so that water droplets that are not vaporized due to insufficient heating are prevented from being sprayed from the steam outlet 131, and the ironing effect is ensured.
