Therefore, the atomization assembly 1 is especially suitable for the situation where the liquid guide body 13 is soft.

The cover body 14 is provided with at least one liquid inlet hole 141 communicating with the liquid guide body 13, for the liquid to contact the liquid guide body 13 through the first opening 112a and the liquid inlet. The cover body 14 is preferably in a plate shape. The cover body 14 is inserted into the first opening 112a and sinks relative to the first side 111a. The shape of the first opening 112a is adapted to the shape of the cover body 14, and the cover body 14 is tightly fitted with the inner wall of the first opening 112a.

The functions of the various parts of the atomization assembly 1 are:

• • 1, The functions of the support housing 11 is to: (1) provide the overall assembling dimension of the atomization assembly 1; (2) support the heating body 12, so that the heating body 12 has the strength and is not easily deformed; (3) act as a container for the liquid guide body 13.
  • 2, The functions of the liquid guide body 13 is to: (1) conduct the liquid 13 and lock the liquid from leakage; (2) be in fully contact with the heating body 12, so that the liquid is conducted to the heating body to be heated and evaporated.
  • 3, The functions of the heating body 12 is to: (1) generate heat when electrified, to heat and evaporated the liquid; (2) provide a supporting force, so that the liquid guide body 13, especially the soft liquid guide body 13, is bound in the support housing 11, and to be in full contact with the liquid guide body 13.
  • 4, The functions of the cover body 14 is to: (1) press the liquid guide body 13, especially the soft liquid guide body 13, so that the volume of the soft liquid guide body 13 is fixed, and the liquid guide ability of the soft liquid guide body 13 is consistent; (2) be provided with the liquid inlet hole 141 on the cover body 14, which can control the liquid inlet amount, so that the liquid inlet amount and the liquid consumption amount can be balanced.

The inner side of the first opening 112a is provided with a first step 114 facing the first side 111a for positioning the cover body 14, and the lower side of the cover body 14 abuts against the first step 114.

The outer side of the support housing 11 is provided with a second step 115 facing the second side 111b. When the atomization assembly 1 is installed in medical treatment, intelligent household electrical appliances, consumer electronic products or other products, the second step 115 is used for positioning the atomization assembly 1.

At least part of the heating body 12 is embedded in the support housing 11 at the second side 111b of the support housing 11, and the lower side of the heating body 12 may be flush with the second side 111b, or may sink relative to the second side 111b.

The heating body 12 includes a heating portion 121, an electrode portion 122 and a connecting portion 123. The heating portion 121 is connected with the electrode portion 122, and the connecting portion 123 is arranged on an edge of the heating portion 121 and/or the electrode portion 122. The connecting portion 123 is embedded in the support housing 11, so that the heating body 12 has strength, and the position of the heating portion 121 corresponds to the second opening 112b. The electrode portion 122 is used to be connected to a lead wire and a battery, and the electrode portion 122 may also be embedded in the support housing 11, so as to realize the connection between the heating body 12 and the support housing 11. The number of the electrode portions 122 is at least two, and the heating portion 121 is connected to at least two electrode portions 122 to form a heating circuit, and heat is generated according to the heating effect of the resistance when the electrodes are energized.

The heating portion 121 includes at least one heating strip 1211, which reflects the heating track of the heating portion 121. The sectional dimension of each heating strip 1211 is smaller than that of the electrode portion 122. Since the electrode portion 122 and the heating strip 1211 are made of a same material, the resistance of the heating strip 1211 is much larger than that of the electrode portion 122. When the electrode portion 122 is connected to and electrified by a power supply, the electrode portion 122 and the heating strip 1211 form a loop with the power supply, and the heating strip 1211 generates heat.

The heating strip 1211 is curved or bent, to form a wave shape or a zigzag shape, and a grid shape may be formed when there are at least two heating strips 1211. The heating strip 1211 has many embodiments, for example, may be a single heating circuit (see FIG. 12 and FIG. 13), double heating circuits (see FIG. 14 and FIG. 15), a wave-shaped heating circuit (see FIG. 12), a zigzag heating circuit (see FIG. 13 and FIG. 15), multiple groups of zigzag or wave-shaped heating circuits may be realized, and a plurality of extremely thin heating strips 1211 may also form a heating net (see FIG. 16). Through this structure, the heating body 12, which was originally easily deformed and difficult to assemble and produce, can be mass produced, and has a good strength and a reliable performance.

The number of the connecting portions 123 is at least two, and a larger number of the connecting portions 123 can improve the firmness of the connection between the heating body 12 and the support housing 11.

Each connecting portion 123 includes a first portion 1231 extending from the heating portion 121 and/or the electrode portion 122 and a second portion 1232 connected with the first portion 1231. In the direction not parallel to (preferably perpendicular to) the extension direction of the first portion 1231, the size of the second portion 1232 is larger than that of the first portion 1231, so that the connection with the support housing 11 is more secure.

The atomization assembly 1 has the characteristics of being easy to produce, and its production method may be as follows:

• • 1, a sheet-like heating body 12 is prepared, wherein a sheet-like metal (such as a nickel-chromium alloy, an iron-chromium-aluminum alloy, a stainless steel alloy, a nickel-based alloy, a titanium, a titanium alloy, etc.) with a relatively high resistivity may be used, and may be cut, chemical etched, laser engraved or the like, to form the sheet-like heating body 12 having the following characteristics.
  • 2, the sheet-like heating body 12 is integrally formed with the support housing 11 through an in-mold injection process, wherein the support housing 11 may be made of a high-temperature-resistant engineering plastic material such as LCP (Liquid Crystal Polymer), PEEK (Polyether Ether Ketone), Nylon, PI (Polyimide), PAI (Polyamide-Imide), PA66 (Polyadiohexylenediamine) or the like; the sheet-like heating body 12 is placed in a forming mold, the molten plastic is filled with the mold by injection molding, the support housing 11 is formed after the plastic is cooled, so that the support housing 11 and the heating body 12 are consolidated together to form the form where part of the heating body 12 is embedded in the support housing 11, then the support housing 11 and the heating body 12 are taken out of the mold, the heating body 12 and the support housing 11 define the accommodation compartment 113 open from the first opening 112a; the heating body 12 is supported by the support housing 11 and thus has a good strength, which is beneficial to mass production.
  • 3, the soft liquid guide body 13 is placed into the accommodation compartment 113 of the support housing 11, and then the cover body 14 is covered. Since the second opening 112b of the support housing 11 is blocked by the sheet-like heating body 12, and the first opening 112a is squeezed by the cover body 14, the volume of the soft liquid guide body 13 in the accommodation compartment 113 is fixed, and its ability to absorb the liquid and lock the oil is stable. The cover body 14 is embedded in the first opening 112a and tightly fitted with the inner wall of the first opening 112a. The cover body 14 is provided with at least one liquid inlet hole 141, and the size of the liquid inlet hole 141 can control the amount of liquid entering the soft liquid guide body 13, so that the amount of liquid inflow can be adjusted according to different concentrations of the liquid and the size of the liquid inlet hole 141, so as to achieve the balance between the liquid supply and the liquid consumption.

The material of the soft liquid guide body 13 may be formed by stacking multiple layers of a fibrous liquid guide material such as a non-woven fabric, a long-staple cotton cloth, a linen fiber cloth or the like, and then is cut into a size and shape matched the first opening 112a of the support housing 11 through a cutter die. The cover body 14 may be formed by injection molding of a plastic or by stamping of a metal.

The atomization assembly 1 thus produced has the characteristics of good strength, high reliability, accurate size, and easy mass production. Moreover, the production material is easy to obtain, the cost is low, and the production process is simple and fast.

In the high strength atomization assembly 1, the heating body 12 with a relatively low strength is combined with the support housing 11 made of a temperature-resistant insulating material with a certain strength, the heating body 12 is provided with an ineffective-heating low-temperature area, and the low-temperature area of the heating body 12 is in contact with the insulating material, so that the heating body 12 has strength, and can be better in contact with the liquid guide body 13 when the soft liquid guide body 13 is used.

Referring to FIG. 8 and FIG. 9, the heating body 12 is in a sheet shape, and the connecting portion 123 may further be bent in the thickness direction of the heating body 12, so that the connecting portion 123 can be embedded in the supporting housing 11 more deeply.

The connecting portion 123 does not form a heating circuit with the heating portion 121 and the electrode portion 122. In other words, when the electrode portion 122 is energized by the power supply, the electrode portion 122, the heating portion 121 and the power supply form a loop, and the heating portion 121 generates heat according to the resistance heating effect, while the connecting portion 123 extending outward is not in the range of the loop and has no current flowing through and does not generate heat, but the heat from the heating circuit in the loop is conducted to the connecting portion 123, and therefore the temperature of the connecting portion 123 is relatively low.

Preferably, the entire heating body 12 is integrally formed.

Referring to FIG. 10 and FIG. 11, the electrode portion 122 protrudes out of the support housing 11, which can facilitate the welding of a lead wire on the electrode portion 122 or the direct contact between the electrode portion 122 and a battery contact.

The atomization assembly 1 of the present invention can be used for atomization of various liquids, for example, in an electronic cigarette to atomize the e-liquid.

Referring to FIG. 17 to FIG. 19, an atomization apparatus in an embodiment of the present invention includes a shell 2 and the above-mentioned atomization assembly 1 connected to the shell 2, and further includes an upper seat 3 arranged in the shell 2. A liquid channel 31 is provided in the upper seat 3, a liquid storage compartment 21 for storing the liquid is provided in the shell 2, and an air outlet hole 21 is provided on the shell 2. The first opening 112a of the support housing 11 of the atomization assembly 1 is sunk into a groove shape to form a liquid inlet groove. The liquid channel 31 of the upper seat 3 communicates the liquid storage compartment 21 with the first opening 112a of the atomization assembly 1. The liquid is in contact with the liquid guide body 13, and conducted to the heating body 12 via the liquid guide body 13, and then heated and atomized by the heating body 12 to generate aerosol, which exits through the air outlet hole 21. The liquid is stored in the liquid storage compartment 21, flows to the first opening 112a of the atomization assembly 1 through the liquid channel 31 of the upper seat 3 and enters the liquid inlet groove (see FIG. 18, wherein the arrows indicate the liquid flow direction), and then flows through the liquid inlet hole 141 on the cover body 14 of the atomization assembly 1 to the liquid guide body 13. Since the gaps in the liquid guide body 13 are small, the liquid will remain on the liquid guide body 13 and will not leak out. When the user inhales, the switch is activated, and the heating body 12 generates heat according the resistance thermal effect, to heat and vaporize the liquid on the liquid guide body 13 in contact with the heating body 12 to form a gas-liquid mixture, which is sucked out by the user through the air outlet hole 21 (see FIG. 19, wherein the arrows indicate the gas flow direction). The atomization apparatus 1 can be used as an electronic cigarette, the liquid storage compartment stores the e-liquid, and the atomization assembly heats and atomizes the e-liquid.

Since the atomization apparatus adopts the above-mentioned high strength atomization assembly 1, thereby having the characteristics of good strength, high reliability, accurate size, and easy mass automatic production. Moreover, the production material is easy to obtain, the cost is low, and the production process is simple and fast.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications, combinations and changes.
