Description

Technical Field

[0001] The present application relates to the technical field of beauty instruments, and in particular to a hot and cold dual-purpose sprayer. Background Art

[0002] Beauty sprayers are widely used in the fields of beauty, health care and physical therapy. Beauty sprayers evaporate water into water mist through the evaporation device in the main unit, and the water mist is sprayed on the skin through the nozzle to achieve the purpose of skin care. Therefore, with the continuous improvement of people's living standards, sprayers for medical beauty have become more and more popular. The existing sprayers are designed with containers for placing Chinese herbal medicine or other aromatherapy materials, so that steam beauty can be combined with physical therapy of Chinese herbal medicine or other aromatherapy materials. However, during use, steam and Chinese herbal medicine or other aromatherapy materials are easily condensed after fumigation or during transmission and cannot be sprayed out. The condensed mixed liquid carries the ingredients of Chinese herbal medicine and presents a color similar to tea. The mixed liquid is easy to remain in the main unit of the sprayer, which is not only difficult to clean, but also easy to breed bacteria. If the mixed liquid flows back into the evaporation device during the spraying process, it is easy to cause the liquid in the evaporation device to become turbid, and even cause the evaporation device to misoperate.

[0008] The hot and cold dual-purpose sprayer disclosed in the present application has a first adapter with a mixing chamber and a reflux port, a mist inlet, a mist outlet and an assembly opening connected to the mixing chamber. The mist inlet is connected to a hot mist generating device, and the mist outlet is connected to a hot mist nozzle. A precipitation cup body loaded with Chinese herbal medicine is inserted into the mixing chamber through the assembly opening. The hot mist generated by the hot mist generating device enters the mixing chamber, enters the precipitation cup body through the through hole on the precipitation cup body, and undergoes a steaming and fumigating effect with the Chinese herbal medicine. After the effective ingredients in the Chinese herbal medicine are fused with the hot mist, they are sprayed from the hot mist nozzle to act on the user's skin. The return bottle is connected to the reflux port through the reflux pipe, and the mixed liquid condensed after the hot mist in the mixing chamber reacts with the Chinese herbal medicine can pass through the reflux port. The liquid is transported to the return water bottle through the reflux port and the reflux pipe for collection, which can not only prevent the mixed liquid with a color similar to tea from entering the hot mist generating device, causing the liquid in the hot mist generating device to become turbid, but also prevent the mixed liquid from remaining in the mixing chamber, thereby reducing the difficulty of cleaning. At the same time, it reduces the influence of bubbles generated by the mixed liquid in the hot mist generating device on the detection accuracy of the liquid level detection system, and avoids the thermal mist generating device from erroneous operation; the return water bottle and the shell are detachable, so the return water bottle can be removed from the shell and cleaned separately, thereby preventing the return water bottle from forming scale and breeding bacteria due to long-term use; at the same time, the mixed liquid collected in the return water bottle can be dumped in time for flexible use.

[0015] In one embodiment, there are multiple through holes, and the projections of the multiple through holes in the vertical direction of the precipitation cup body are all outside the range of the mist outlet.

[0016] The hot and cold dual-purpose sprayer in the above embodiment further limits the projections of the multiple through holes in the mixing chamber to be located outside the range of the mist outlet, so that after the hot mist generating device stops working, the precipitation in the cup body drops due to the temperature drop, and condensation occurs in the cup body and its surroundings, and the condensed liquid is discharged from the through holes. By arranging the through holes outside the top of the mist inlet, the condensed liquid can be prevented from dripping onto the mist inlet.

[0017] In one embodiment, the height of the reflux port on the housing is higher than the height of the water return bottle on the housing, and the height of the reflux pipe on the housing gradually decreases in the path direction from the reflux port to the water return bottle.

[0018] The dual-purpose cold and hot sprayer in the above embodiment further limits the height of the reflux pipe on the outer shell to gradually decrease in the path direction from the reflux port to the return water bottle, so that the condensed liquid can slide into the return water bottle in the reflux pipe solely by its own gravity, without adding a pump body structure, making the sprayer of the present application simple in structure and reducing costs.

[0019] In one embodiment, the sprayer further comprises a sealing cover, which is arranged at the assembly opening in the first adapter, the sealing cover is detachably connected to the first adapter, and the sealing cover is used to seal the assembly opening.

Specifically, the first connecting column is formed on the third adapter of the hot mist generating device. The diameters of the first connecting column and the second connecting column are slightly larger than the return pipe. When the first connecting column and the second connecting column are respectively inserted into the return pipe, the opening of the return pipe undergoes elastic deformation, and the first connecting column and the second connecting column are respectively interference fit with the return pipe, so that the connection between the return pipe and the first connecting column and the second connecting column is stable. Based on the above-mentioned fit, the assembly between the first adapter and the return water bottle is simple, and it is convenient to disassemble, clean and replace.

[0024] In one of the embodiments, the water return bottle includes a bottle body and a second adapter, the second adapter is fixedly arranged on the shell, and the second adapter and the bottle body are detachably connected by a threaded connection.

[0025] The hot and cold dual-purpose sprayer in the above embodiment further defines that the water return bottle is composed of at least a bottle body and a second adapter, and the shell can be detachably connected to the second adapter by a threaded connection, so that the bottle body can be removed separately for cleaning; the second adapter can be fixed to the shell by the cooperation of the screw and the threaded hole.
