[0023] In the above-described solution of this application, the handheld beauty spray device includes a first housing and a second housing, which are detachably connected, thus facilitating easier assembly and disassembly. A receiving cavity is provided between the first and second housings, and the receiving cavity houses a jet assembly, a first mounting base, and a second mounting base. The jet assembly includes a first tube, a second tube, and a solenoid valve. The solenoid valve includes an inlet end and an outlet end, and the first and second tubes are respectively connected to the inlet and outlet ends of the solenoid valve.

[0037] In some embodiments of this application, the jet assembly 3 also includes a handle connected to the solenoid valve 32, and the handle can extend into the space between the first vertical housing and the second vertical housing.

[0038] In some embodiments of this application, the first mounting base 4 is used to mount the essence bottle 8, and the second mounting base 5 is used to mount the high-pressure gas cylinder.

[0039] In some embodiments of this application, the first mounting base 4 is a hollow cylindrical structure with a partition inside. The upper surface of the partition and the inner wall of the hollow cylindrical structure together form a first positioning groove. The lower surface of the partition is provided with a liquid outlet connector, and at least two through holes are provided through the liquid outlet connector. The essence bottle 8 is placed in the first positioning groove, and the essence in the essence bottle 8 enters the liquid inlet pipe through the through holes in the liquid outlet connector, and then enters the first tube body 31 through the liquid inlet pipe.

[0041] In some embodiments of this application, the second mounting base 5 is a hollow cylindrical structure, which is sandwiched between the tail ends of the first transverse shell and the second transverse shell.

[0042] In some embodiments of this application, the second tube 33 and the solenoid valve 32 being a separate structure means that the second tube 33 and the solenoid valve 32 are relatively separate, and are formed separately during molding, that is, the second tube 33 and the solenoid valve 32 are not an integral structure.

[0043] In some embodiments of this application, the essence bottle 8 and the first mounting base 4 are separate structures, meaning that the essence bottle 8 and the first mounting base 4 are relatively separate, and are formed separately during molding, that is, the essence bottle 8 and the first mounting base 4 are not an integral structure.

[0044] In some embodiments of this application, the fourth silicone sleeve 19 and the nozzle 9 being a separate structure means that the fourth silicone sleeve 19 and the nozzle 9 are relatively separate, and are formed separately during molding, that is, the fourth silicone sleeve 19 and the nozzle 9 are not an integral structure.

[0045] In some embodiments of this application, the nozzle 9 and the heating wire being a separate structure means that the nozzle 9 and the heating wire are relatively separate, and are formed separately during molding, that is, the nozzle 9 and the heating wire are not an integral structure.

[0046] In some embodiments of this application, the first silicone sleeve 15, the second silicone sleeve 16, the third silicone sleeve 18, and the ejector pin assembly 17 are separate structures, meaning that the first silicone sleeve 15, the second silicone sleeve 16, the third silicone sleeve 18, and the ejector pin assembly 17 are relatively separated from each other and are molded separately. That is, the first silicone sleeve 15, the second silicone sleeve 16, the third silicone sleeve 18, and the ejector pin assembly 17 are not an integral structure.

[0047] In the above-described solution of this application, the handheld beauty sprayer includes a first housing 1 and a second housing 2, which are detachably connected, making it easier to assemble and disassemble the first housing 1 and the second housing 2. A receiving cavity is provided between the first housing 1 and the second housing 2, and the receiving cavity houses a jet assembly 3, a first mounting base 4, and a second mounting base 5. The jet assembly 3 includes a first tube 31, a second tube 33, and a solenoid valve 32. The solenoid valve 32 includes an inlet end and an outlet end. The first tube 31 and the second tube 33 are respectively connected to the inlet end and the outlet end of the solenoid valve 32. Thus, the connection between the first tube 31 and the second tube 33 can be controlled by the solenoid valve 32. The first mounting base 4 is provided with a first positioning groove and a liquid inlet pipe. One end of the liquid inlet pipe is connected to the first positioning groove, and the other end is connected to the first tube 31. The first positioning groove is used to install an essence bottle 8. The bottle opening of the essence bottle 8 is connected to the liquid inlet pipe, so that the essence in the essence bottle 8 can flow into the first tube 31 through the liquid inlet pipe. The first mounting base 4 is inclinedly disposed above the first tube 31. The first positioning groove is a cylindrical groove. The axis of the cylindrical groove and the axis of the liquid inlet pipe are collinear and the angle between the cylindrical groove and the axis of the first tube 31 is an acute angle. This facilitates the flow of the essence into the first tube 31 and facilitates the high-pressure gas to drive the essence out of the first tube 31. The second mounting base 5 is provided with a second positioning groove and an air inlet pipe. One end of the air inlet pipe is connected to the second positioning groove, and the other end is connected to the second tube 33. The second positioning groove is used to install a high-pressure gas cylinder. The mouth of the high-pressure gas cylinder is connected to the air inlet pipe. This facilitates the flow of high-pressure gas into the second tube 33. With this structure, the high-pressure gas in the high-pressure cylinder can serve as a power source to drive the essence in the essence bottle 8 to be sprayed out through the first tube 31. The solenoid valve 32 can act as a switch to control the connection between the first tube 31 and the second tube 33. When the first tube 31 and the second tube 33 are connected, the high-pressure gas in the high-pressure cylinder flows through the second tube 33 into the first tube 31, creating a negative pressure environment within the first tube 31. Under this negative pressure, the essence in the essence bottle 8 can flow into the first tube 31 and be sprayed out through it. At this time, the beauty sprayer is in working condition. When the first tube 31 and the second tube 33 are disconnected, the beauty sprayer is not working.

[0048] Since the beauty spray device described in this application does not use an electric pump to drive the essence spraying, it avoids the problem of excessive noise from an electric pump, which would lead to a poor user experience. The beauty spray device described in this application is small in size, easy to carry, operates with low noise, and provides a good user experience. When the essence is sprayed from the nozzle 9 under pressure, it can be sprayed in a mist, thus meeting the user's needs. The fourth silicone sleeve 19, when placed between the nozzle 9 and the front cover 7, can improve the sealing performance between the nozzle 9 and the front cover 7.

[0049] In addition, when a first silicone sleeve 15, a second silicone sleeve 16, a third silicone sleeve 18, and a pin assembly 17 are provided between the high-pressure gas cylinder and the second tube 33, the stability and sealing of the connection between the high-pressure gas cylinder and the second tube 33 can be further improved.

[0050] In some embodiments of this application, a pressure regulating valve is also provided within the receiving cavity. The nozzle 9 is connected to the first tube 31, and the pressure regulating valve is located between the first tube 31 and the nozzle 9. The pressure regulating valve is used to regulate the gas pressure within the first tube 31. With this structure, the pressure regulating valve can adjust the gas pressure within the first tube 31, thereby ensuring the atomization effect and safety of the beauty sprayer.

[0051] In some embodiments of this application, the pressure regulating valve is an existing device for regulating and controlling fluid pressure, widely used in various systems to ensure a stable fluid supply. The pressure regulating valve and the solenoid valve 32 are connected in series.

[0052] In some embodiments of this application, a pressure relief valve 10 is also provided within the receiving cavity. The pressure relief valve 10 is located between the second pipe body 33 and the second mounting base 5, and the high-pressure gas cylinder is a high-pressure carbon dioxide cylinder. Using this structure, pressure relief via the pressure relief valve 10 can prevent excessive pressure in the pipeline from affecting the safe operation of the equipment. When the high-pressure gas cylinder is a high-pressure carbon dioxide cylinder, high-pressure carbon dioxide gas can be used to drive the essence liquid to spray out.

[0053] In some embodiments of this application, the pressure relief valve 10 is an important safety device, also known as a safety valve, mainly used to protect equipment and pipelines by automatically opening and releasing pressure when the pressure is too high, preventing accidents. The pressure relief valve 10 is usually installed on equipment or pipelines in closed systems. When the pressure in the system exceeds a set value, the pressure relief valve 10 will automatically open to release the excess pressure to the atmosphere, thereby ensuring that the pressure of the medium in the equipment and pipelines remains within a safe range.

[0054] In some embodiments of this application, the pressure relief valve 10 and the high-pressure carbon dioxide cylinder are connected in parallel.

[0055] In some embodiments of this application, such as Figure 3 As shown, the inner wall of the first housing 1 is provided with two first clamping plates 11, which are disposed at both ends of the solenoid valve 32. The second housing 2 is provided with two second clamping plates, and the solenoid valve 32 is clamped between the first clamping plates 11 and the second clamping plates. With this structure, the two ends of the solenoid valve 32 are clamped together by the cooperation of the two first clamping plates 11 and the two second clamping plates, thereby improving the stability of the solenoid valve 32 installation and thus improving the overall stability of the beauty sprayer.

[0056] In some embodiments of this application, the first clamping plate 11 includes a first base plate and two first side plates, which are disposed on opposite sides of the first base plate and protrude from the first base plate. The first base plate and the two first side plates together form a first limiting groove, in which one side of the solenoid valve 32 is limited and fitted. The second clamping plate includes a second base plate and two second side plates, which are disposed on opposite sides of the second base plate and protrude from the second base plate. The second base plate and the two second side plates together form a second limiting groove, in which the other side of the solenoid valve 32 is limited and fitted. This structure can further improve the stability of the solenoid valve 32 during installation.

[0057] In some embodiments of this application, such as Figure 3 As shown, the two first side plates on the first clamping plate 11 away from the nozzle 9 are both columnar support structures with a first internal thread. The two second side plates on the second clamping plate away from the nozzle 9 are both columnar support structures with a second internal thread. The screw passes through the first internal thread and the second internal thread in sequence for threaded connection, which can improve the overall stability of the beauty sprayer.

[0058] In some embodiments of this application, such as Figure 3As shown, the cavity also includes a button 6 and a button circuit board 12. The button 6 includes a pressing block with an annular protrusion at one end. The first housing 1 has a first button groove, and the second housing 2 has a second button groove. The pressing block is clamped in the first and second button grooves. The inner walls of the first and second housings are both limited to the annular protrusion. The surface of the pressing block away from the button circuit board 12 has multiple protrusions. The surface of the pressing block away from the button circuit board 12 includes a vertical surface and two inclined surfaces, which are located on both sides of the vertical surface. The button circuit board 12 includes a circuit board and a trigger switch. The trigger switch and the circuit board are electrically connected. The button 6 abuts against the trigger switch. The solenoid valve 32 is electrically connected to the circuit board. One end of the circuit board has an insertion groove. The first housing 1 has an insertion block that is inserted into the insertion groove. The insertion block and the insertion groove are inserted into each other. The other end of the circuit board has a wire connector. The first housing 1 and the second housing 2 have connector holes. The wire connector extends through the connector holes and has a through hole inside. With this structure, when the user presses button 6, button 6 applies pressure to the trigger switch on the circuit board, causing the trigger switch to activate. Upon receiving the activation signal from the trigger switch, the circuit board can control the solenoid valve 32 to open or close. When the inner walls of both the first housing 1 and the second housing 2 are matched with the annular protrusion, the reliability of button 6 installation is improved, preventing button 6 from falling off after installation. The insertion block and insertion slot, when fitted together, improve the stability of the circuit board installation. When the wire connector is sandwiched between the first housing 1 and the second housing 2, it not only improves the stability of the wire connector installation but also allows the wire to pass through the through-hole in the wire connector, improving the convenience of wire installation and connection.

[0059] In some embodiments of this application, a display panel 13 is further provided within the receiving cavity, and a display hole is provided on the second housing 2. The display panel 13 is embedded in the display hole. The display panel 13 includes a main board and a display screen. The main board is a circular plate with three fastening holes along its circumference. The fastening holes and the second housing 2 are fastened together by threaded fasteners. With this structure, information such as the pressure in the pipeline and the working status of the solenoid valve 32 can be displayed through the display panel 13, making it more convenient for users.

[0060] In some embodiments of this application, a first housing 1 is provided with a first arc-shaped groove 14, a second housing 2 is provided with a second arc-shaped groove, a first mounting base 4 is sandwiched between the first arc-shaped groove 14 and the second arc-shaped groove, a sealing ring is provided at one end of the first mounting base 4, a first sealing groove is provided on the first housing 1, a second sealing groove is provided inside the second housing 2, and the sealing ring is sandwiched within the first sealing groove and the second sealing groove. With this structure, when the first mounting base 4 is sandwiched between the first arc-shaped groove 14 and the second arc-shaped groove, the stability of the installation of the first mounting base 4 can be improved; when the sealing ring is sandwiched within the first sealing groove and the second sealing groove, the reliability of the sealing ring installation can be improved, thereby improving the sealing performance of the beauty sprayer.

[0061] In some embodiments of this application, the opening of the first sealing groove faces the second housing 2, and the opening of the second sealing groove faces the first housing 1.

[0062] In some embodiments of this application, a fixing seat 20 is also provided in the receiving cavity. The fixing seat 20 and the first housing 1 are detachably connected. The nozzle 9 is installed on the fixing seat 20. This structure can improve the stability of the connection between the nozzle 9 and the first tube 31.

[0063] In some embodiments of this application, the front cover 7 has a conical structure.

[0064] In some embodiments of this application, the operation of the beauty sprayer is as follows: First, the device is started, and the user presses button 6. Button 6 applies pressure to the trigger switch, causing the trigger switch to generate an electrical signal. At this time, the circuit board controls the solenoid valve 32 to open, and the high-pressure gas in the high-pressure gas cylinder is transmitted to the nozzle 9 through the second tube 33 and the first tube 31. The essence in the essence bottle 8 flows into the first tube 31 under negative pressure and is sprayed out in a mist form through the nozzle 9.
