Description

Technical Field

[0001] This utility model relates to the field of beauty instruments, specifically a filter head for beauty instruments with a float structure. Background Technology

[0002] Beauty instruments are machines that regulate and improve the body and face based on human physiological functions. Current beauty instruments require a filter head to remove impurities from essential oils during use. However, existing beauty instrument filters do not allow for timely interruption of the essential oil filtration process when the filter head becomes full of impurities, causing continuous filtration and potentially damaging the filter head and filter itself.

[0003] To address the aforementioned issues, a filter head for beauty instruments with a float structure is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide a filter head for a beauty instrument with a float structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter head for a beauty instrument with a float structure, comprising a lower housing, an upper housing engaged at the top of the lower housing, a liquid guide seat fixedly disposed at the middle of the top of the inner wall of the upper housing, positioning seats fixedly disposed on both sides of the top of the inner wall of the upper housing, positioning holes opened at the bottom of the two positioning seats, positioning rods engaged inside the two positioning holes, a guide seat fixedly disposed at the bottom between the two positioning rods, a guide hole opened at the middle of the guide seat, a guide rod inserted through the guide hole, a sealing head fixedly connected to the top of the guide rod, the sealing head corresponding to the liquid guide seat, a float fixedly connected to the bottom of the guide rod, a filter engaged at the middle of the top of the guide seat, and the filter engaged with the liquid guide seat.

[0006] The beauty device's filter head introduces essential oil mixed with impurities into the filter head through the inlet, and then filters the essential oil through the filter. Clean essential oil is then drawn out through the liquid guide seat and the outlet, while impurities remain inside the filter head. As the amount of impurities inside the filter head increases, the float gradually rises, which in turn drives the guide rod and the sealing head to rise until the sealing head is tightly connected to the liquid guide seat's outlet, thus sealing the liquid guide seat and preventing the essential oil from being discharged. This timely interruption of the essential oil filtration operation prevents the continuous filtration process from damaging the filter head and filter.

[0007] Preferably, one side of the upper housing is fixedly connected to an inlet and an outlet. One end of the outlet extends into the interior of the upper housing and is connected to the liquid guide seat. A fixing member is provided in the middle between the inlet and the outlet. A connector is engaged on one side of the fixing member. Two liquid guide tubes are provided at the end of the connector away from the fixing member. Essential oil mixed with dirt is introduced into the filter head through the inlet.

[0008] Preferably, two second sealing rings are provided at the connection between the connector and the fixing member, which can improve the sealing performance.

[0009] Preferably, a fixing seat is fixedly provided on both sides of the connector, and two fixing posts are fixedly connected to the surface of the fixing member. Fixing holes are provided at one end of the two fixing posts and in the middle of the two fixing seats. The connection between the connector and the fixing member is facilitated by the cooperation of the two fixing posts and the two fixing seats.

[0010] Preferably, a first sealing ring is provided at the connection between the lower housing and the upper housing, which can improve the sealing performance of the filter head.

[0011] Preferably, the top of the lower housing surface has two through slots, and the bottom of one side of the inner wall of each of the two through slots has a limiting groove. Limiting blocks are fixedly provided on both sides of the inner wall of the upper housing. The two limiting blocks are respectively provided with the two through slots and the two limiting grooves. By covering the lower housing with the upper housing and ensuring that the two limiting blocks are inserted into the two through slots, and then rotating the upper housing, the two limiting blocks are respectively engaged in the two limiting grooves, thereby realizing the quick connection between the upper housing and the lower housing.

[0012] Preferably, a plurality of reinforcing strips are provided at the middle of the surface of the lower shell and the middle of the surface of the upper shell. The provision of a plurality of reinforcing strips can improve the structural strength of the lower shell and the upper shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The filter head of this beauty instrument introduces essential oil mixed with dirt into the filter head through the liquid inlet, and then filters the essential oil through the filter. The clean essential oil is drawn out through the liquid guide seat and the liquid outlet, while the dirt remains inside the filter head. As the dirt inside the filter head increases, the float will gradually rise, which in turn drives the guide rod and the sealing head to rise until the sealing head is tightly connected to the liquid guide port of the liquid guide seat, thereby sealing the liquid guide seat and preventing the essential oil from being discharged. This interrupts the essential oil filtration operation in time, avoiding the continuous essential oil filtration operation from damaging the filter head and the filter. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-5This utility model provides a filter head for a beauty instrument with a float structure, including a lower housing 1, an upper housing 2 that is engaged at the top of the lower housing 1, a liquid guide seat 20 fixedly disposed at the middle of the top of the inner wall of the upper housing 2, and positioning seats 22 fixedly disposed on both sides of the top of the inner wall of the upper housing 2. Positioning holes 23 are opened at the bottom of each of the two positioning seats 22, and positioning rods 13 are engaged inside each of the two positioning holes 23. A guide seat 9 is fixedly disposed at the bottom between the two positioning rods 13, and a guide hole 19 is opened in the middle of the guide seat 9. A guide rod 10 is inserted through the guide hole 19, and a sealing head 11 is fixedly connected to the top of the guide rod 10. The sealing head 11 is correspondingly disposed with the liquid guide seat 20. A float 12 is fixedly connected to the bottom of the guide rod 10. A filter 14 is fitted into the middle of the top of the seat 9. The filter 14 is engaged with the liquid guide seat 20. The filter head of this beauty instrument introduces essential oil mixed with dirt into the filter head through the liquid inlet 16, and then filters the essential oil through the filter 14. The clean essential oil is then drawn out through the liquid guide seat 20 and the liquid outlet 17, while the dirt remains inside the filter head. As the dirt inside the filter head increases, the float 12 will gradually rise, which will drive the guide rod 10 and the sealing head 11 to rise gradually until the sealing head 11 is tightly connected to the liquid guide port of the liquid guide seat 20, thereby sealing the liquid guide seat 20 and preventing the essential oil from being discharged. This interrupts the essential oil filtration operation in time, preventing the essential oil filtration operation from continuing and causing damage to the filter head and filter 14.

[0022] One side of the upper housing 2 is fixedly connected to an inlet 16 and an outlet 17. One end of the outlet 17 extends into the interior of the upper housing 2 and is connected to the liquid guide seat 20. A fixing member 3 is provided in the middle between the inlet 16 and the outlet 17. A connecting member 4 is engaged on one side of the fixing member 3. Two liquid guide tubes 5 are provided at the end of the connecting member 4 away from the fixing member 3. Two second sealing rings 18 are provided at the connection between the connecting member 4 and the fixing member 3. Fixing seats 25 are fixedly provided on both sides of the connecting member 4. Two fixing posts 24 are fixedly connected to the surface of the fixing member 3. Fixing holes 26 are provided at one end of the two fixing posts 24 and in the middle of the two fixing seats 25.

[0023] In use, essential oil mixed with dirt is introduced into the filter head through the liquid inlet 16. The two second sealing rings 18 can improve the sealing performance. The two fixing posts 24 and the two fixing seats 25 are designed to facilitate the connection of the connector 4 and the fixing part 3.

[0024] A first sealing ring 15 is provided at the connection between the lower housing 1 and the upper housing 2. Two through grooves 7 are opened at the top of the surface of the lower housing 1. Limiting grooves 8 are opened at the bottom of one side of the inner wall of the two through grooves 7. Limiting blocks 21 are fixedly provided on both sides of the inner wall of the upper housing 2. The two limiting blocks 21 are respectively provided with the two through grooves 7 and the two limiting grooves 8. Several reinforcing strips 6 are provided in the middle of the surface of the lower housing 1 and the middle of the surface of the upper housing 2.

[0025] In use, the sealing performance of the filter head can be improved by setting the first sealing ring 15. By covering the lower housing 1 with the upper housing 2 and ensuring that the two limiting blocks 21 are inserted into the two through slots 7, and then rotating the upper housing 2, the two limiting blocks 21 are respectively locked into the two limiting slots 8, thereby realizing the quick connection between the upper housing 2 and the lower housing 1. The setting of several reinforcing strips 6 can improve the structural strength of the lower housing 1 and the upper housing 2.

[0026] In this embodiment, the beauty instrument's filter head introduces essential oil mixed with impurities into the filter head through the inlet 16, and then filters the essential oil through the filter 14. The clean essential oil is then drawn out through the liquid guide seat 20 and the outlet 17, while the impurities remain inside the filter head. As the amount of impurities inside the filter head increases, the float 12 gradually rises, which in turn drives the guide rod 10 and the sealing head 11 to rise until the sealing head 11 is tightly connected to the liquid guide port of the liquid guide seat 20, thereby sealing the liquid guide seat 20 and preventing the essential oil from being discharged. This interrupts the essential oil filtration operation in time, preventing the continuous essential oil filtration operation from damaging the filter head and the filter 14. During use, by covering the lower housing 1 with the upper housing 2 and ensuring that the two limiting blocks 21 are inserted into the two through slots 7, and then rotating the upper housing 2, the two limiting blocks 21 are respectively engaged in the two limiting slots 8, thereby achieving a quick connection between the upper housing 2 and the lower housing 1.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
