[0021] The present invention is further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, an air pump type beauty sprayer of the present invention comprises a housing 1, the housing 1 comprises a fixing seat 13 and an upper shell 11 and a lower shell 12 respectively fixed on both sides of the fixing seat 13, wherein there is a storage space for accommodating the upper component between the upper shell 11 and the fixing seat 13, and there is a storage space for accommodating the lower component between the lower shell 12 and the fixing seat 13. In order to enable the upper shell 11 to be separated from the fixing seat 13, the side wall of the fixing seat 13 is vertically and symmetrically provided with elastic buckles 131, and matching through holes are provided at the corresponding positions of the upper shell 11 and the elastic buckles 131, and the elastic buckles 131 are installed on the through holes, and the upper shell 11 and the fixing seat 13 can be separated by pinching the elastic buckles 131 on both sides.

[0023] like Figure 2As shown, the lower component includes an air pump 2 and a battery 21 for powering the air pump 2. The air pump 2 is used to generate compressed air. The battery 21 is provided with a charging port 211 for connecting an external power source. The lower shell 12 is also provided with a through hole at the position of the charging port 21. The top of the air pump 2 has an exhaust pipe (not shown in the figure) extending toward the upper component, and the exhaust pipe is connected to the upper component, so that the air pump 2 can provide compressed air to the upper component. The lower component also includes a PCB board 22 for controlling the start of the battery 21.

[0024] like Figure 2-5 As shown, the upper component includes a kettle body 3, a spray head component passing through the kettle body 3, and a connecting sleeve 6 connected to the lower end of the kettle body 3. The kettle body 3 has a hollow liquid storage cavity 301 for accommodating liquid, and the kettle body 3 is provided with a liquid guide port 311 on its top end surface for pouring liquid, and a kettle cover 33 is provided on the liquid guide port 311 for sealing the liquid guide port 311. The spray head component and the kettle body 3 are vertically arranged, and there is a liquid infusion channel 40 between the kettle body 3 and the spray head component. Specifically, the liquid infusion channel 40 includes a first gap 401 between the inner wall of the kettle body 3 and the outer surface of the spray head component, and a cavity 402 in the spray head component. The cavity 402 is connected to the first gap 401, and the cavity 402 is provided with a spray port on the end surface of the spray head component, and the spray port can be opened or closed with the axial movement of the spray head component. The liquid infusion channel 40 passes through the liquid storage cavity 301 of the kettle body 3, so that the liquid in the liquid storage cavity 301 can fill the liquid infusion channel 40 and then be sprayed out through the spray port.

[0025] The kettle body 3 includes an upper kettle body 31 connected to the kettle cover 33 and a lower kettle body 32 for the nozzle assembly to pass through. The upper kettle body 31 and the lower kettle body 32 are arranged in an interlocking manner. The lower end of the liquid storage cavity 301 of the upper kettle body 31 is arranged in an inverted cone shape, so that the liquid can quickly enter the lower kettle body 32. The liquid storage cavity 301 of the lower kettle body 32 is also arranged in an inverted cone shape, so that a smaller volume of liquid can be used to fill the liquid storage cavity 301 of the lower kettle body 32.

[0026] The nozzle assembly includes a spray needle 4 that passes through the lower pot body 32. One end of the spray needle 4 is fixed on the spray needle seat 41, and the other end passes through the nozzle seat 5 and the sleeve 52. The spray needle seat 41 is nested at one end of the lower pot body 32. The spray needle seat 41 can drive the spray needle 4 to reciprocate along the axial direction of the spray needle 4. The nozzle seat 5 is fixed at the other end of the lower pot body 32. The nozzle seat 5 is provided with a nozzle 51 that is sleeved outside the spray needle 4. The nozzle 51 extends axially toward the direction of the sleeve 52 and passes through the sleeve 52. The sleeve 52 is fixed on the nozzle seat 5. The spray needle seat 41, the spray needle 4, the nozzle seat 5 and the sleeve 52 are coaxial. The gaps between the needle seat 41 and the lower pot body 32, the needle 4 and the lower pot body 32, the nozzle seat 5, and the nozzle 51 form the above-mentioned infusion channel 40, wherein the first gap 401 is the gap between the lower pot body 32 and the needle seat 41 and the needle 4, the cavity 402 is the gap between the needle 4 and the nozzle seat 5 and the nozzle 51, and the spray port is the gap between the needle 4 and the nozzle port 511 of the nozzle. In order to enable the spray port to be opened or closed as the needle 4 moves, the diameter of the end of the needle 4 close to the nozzle 51 gradually decreases, and the diameter of the nozzle port 511 is smaller than the maximum diameter of the needle 4. Therefore, when the needle 4 moves toward the nozzle 51, the diameter of the needle 4 is larger than the diameter of the nozzle port 511, the needle 4 blocks the nozzle port 511, and the spray port is closed; when the needle 4 moves away from the nozzle 51, the diameter of the needle 4 is smaller than the nozzle port 511, the spray port is opened, and as the distance of the needle 4 moving increases, the diameter of the spray port gradually increases.

[0027] The connecting sleeve 6 connected to the lower end of the lower kettle body 32 is connected to the exhaust pipe of the air pump 22. At the same time, a ventilation channel 302 for compressed air circulation is provided in the lower kettle body 32. A certain interval is formed between the nozzle seat 5 and the lower kettle body 32, and between the nozzle seat 5 and the sheath 52 to form a first partition layer 501 and a second partition layer 502 for accommodating compressed air. The nozzle seat 5 is provided with a vent hole 53 connecting the first partition layer 501 and the second partition layer 502. The first partition layer 501 is connected to the ventilation channel 302. The sheath 52 is provided with an exhaust port 521 connecting the second partition layer 502 and the outside. At the same time, the nozzle 51 passes through the exhaust port 521 and has a distance from the exhaust port 521. When the compressed air passes through the ventilation channel 302, fills the first partition layer 501 and the second partition layer 502 in turn, and is discharged to the outside of the sheath 52, the pressure outside the sheath 52 becomes smaller due to the fast discharge velocity of the compressed air, forming a negative pressure. In order to enhance the effect of the negative pressure, the sheath 52 extends a circle of periphery 522 along its axial direction in the direction away from the nozzle 51, so that the periphery 522 forms a circle of independent space. When negative pressure is formed outside the sheath 52, the liquid in the infusion channel 40 is sprayed out from the spray port in a mist due to the pressure difference, and the arrangement of the first spacer layer 501 and the second spacer layer 502 gradually reduces the pressure outside the sheath 52, avoiding the liquid from being sprayed out too quickly and forcefully due to a sharp decrease in pressure, causing harm to the human body. In order to prevent the compressed air from being too strong and causing the connecting sleeve 6 to shake, a circle of protective sleeve 61 is arranged outside the connecting sleeve 6, and the protective sleeve 61 is fixed on the fixing seat 13.

[0028] In order to control the movement of the spray head assembly, a vertically arranged button 7 is provided on the side of the spray head assembly away from the spray port, and a transmission device is connected between the button 7 and the spray head assembly, and the transmission device can convert the vertical downward force of pressing the button 7 into a pulling force to pull the spray head assembly horizontally, so that the button 7 and the spray head assembly are close to each other, and the spray port is opened. An elastic member 72 is also provided between the button 7 and the spray head assembly, so that the button 7 and the spray head assembly always have a tendency to move away from each other, so that when the force acting on the button 7 disappears, the spray head assembly moves along its axial direction in the direction away from the button 7, and the spray port is closed. At the same time, in order to enable the air pump 2 and the spray port to be opened at the same time, the PCB board 22 is located directly below the button 7 and the control end 221 of the PCB board 22 is against the lower end of the button 7. When the button 7 is pressed downward, the button 7 presses the control end 221 of the PCB board 22, and the PCB board 22 controls the battery 21 to supply power to the air pump 2, and the air pump 2 is opened. Preferably, the transmission device includes a transmission rod 71 disposed on both sides of the needle seat, one end of the transmission rod 71 abuts against a support 411 protruding radially from the needle seat 41, and the other end is connected to the button 7, and the cross section of the transmission rod 71 is L-shaped. When the button 7 moves downward, the end of the transmission rod 71 connected to the button 7 rotates downward around the axis, and the end of the transmission shaft 71 abutting against the needle seat 41 also rotates in the same direction, thereby driving the needle seat 41 to move toward the direction close to the button 7.

[0029] The working process of an air pump type beauty sprayer of the present invention is as follows:

[0030] First, pour the liquid into the kettle body 3 so that the liquid fills the liquid storage chamber 301 and the infusion channel 40; then press the button 7 to move the button 7 downward, and the lower end of the button 7 triggers the control end 221 of the PCB board 22, which controls the battery 21 to power the air pump 2, and the air pump 2 generates compressed air. The compressed air enters the ventilation channel 302 of the lower kettle body 32 through the exhaust pipe and the connecting sleeve 6, and then fills the first spacer layer 501 and the second spacer layer 501, and is discharged from the exhaust port 521 on the sheath 52, so that the outside of the sheath 52 is negative pressure; at the same time, when the button 7 moves downward, the end of the transmission rod 71 connected to the button 7 rotates downward around the axis, and the other end of the transmission rod 71 rotates around the axis in the same direction, pushing the spray needle seat 41 to move in the direction close to the button 7, driving the spray needle 4 to move in the direction away from the nozzle 51, and the spray port When the spray nozzle 51 is opened, the liquid in the infusion channel 40 is sprayed out from the spray nozzle in the form of mist due to the pressure difference on both sides of the spray nozzle. Moreover, the further the button 7 moves downward, the greater the distance the needle holder 41 moves. The greater the distance the needle 4 is away from the nozzle 51, the larger the diameter of the spray nozzle and the larger the spray. Finally, when the spray is completed, the button 7 is released, the button 7 returns to its original position, the control end of the PCB board 22 is closed, the battery 21 stops supplying power to the air pump 2, the air pump 2 stops generating compressed air, the pressure outside the sheath 52 returns to normal pressure, and at the same time, when the button 7 returns to its original position, the transmission rod 71 has no pushing effect on the needle holder, and the elastic member 72 arranged between the needle holder 41 and the button 7 causes the needle holder 41 to move in the direction away from the button 7, and the needle 4 moves toward the nozzle 51 until it blocks the nozzle opening 511, the spray nozzle is closed, and the spray stops.

[0031] Comparative experiment of spray pressure

[0032] Instrument: One beauty sprayer of the above structure was used as the experimental group, and five beauty sprayers of various brands (Jindao, Miyang, Qinglin, Sujiangniao, and Pentium) sold on the market were used as the control group, and were marked as control groups 1-5 respectively.

[0033] Test plan: Add lotion (need to be diluted with 80% water), perfume, essential oil, sunscreen and liquid foundation to the experimental group and the control group respectively, observe whether spray is sprayed and the shape of the spray, and spray the spray directly at a distance of 20 cm from the pressure detector, and record the maximum pressure value. The results are shown in Table 1-5.

[0045] As can be seen from Tables 1-5, the commercially available sprayers have particularly high requirements for the liquid used. Only lotion diluted with natural mineral water can spray out a mass spray. Liquids with slightly higher viscosity will block the spray hole and cannot form a spray. At the same time, the spray sprayed by the commercially available sprayer has no pressure and can only adhere to the skin and rely on the natural absorption of the skin, with low absorption efficiency. Finally, the small molecule water mist formed by high frequency will carry static electricity, easily adsorb dust particles in the air, etc., which also has a certain impact on the skin. The air pump type beauty sprayer of the present invention overcomes the shortcomings of the current commercially available sprayers. At the same time, when the diameter of the spray port is small, the spray is in a mass shape and the spray pressure is small. When the diameter of the spray port is large, the spray is in a cone shape and the spray pressure is large. Therefore, the speed and amount of the spray can be adjusted independently according to the user's tolerance, and the structure is simple and cleaning is also very convenient.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
