Description

Technical Field

[0001] This utility model belongs to the field of cleaning handle technology, and particularly relates to a concealed air outlet structure and a body cleaning handle. Background Technology

[0002] Among various electrical appliances, the air outlet structure is a key component affecting the device's performance, appearance, and user experience. Existing air outlet structures typically employ a fixed design, with the air outlet directly exposed, a design that has many drawbacks.

[0003] From an appearance perspective, fixed air outlets are clearly visible even when the equipment is not in operation, which disrupts the simplicity and unity of the overall appearance of the equipment, reduces the aesthetics and design sense of the product, and makes it difficult to meet modern consumers' pursuit of exquisite and fashionable home appliances.

[0004] In terms of space utilization, fixed air outlets occupy a certain amount of external space, causing inconvenience to users. Moreover, the protruding air outlet structure is also prone to damage during transportation, increasing the equipment's maintenance costs and usage risks.

[0005] Furthermore, the fixed air outlet structure used in existing household appliances is inadequate in terms of dust prevention, waterproofing, and cleaning. This not only affects airflow performance but may also breed bacteria, posing a potential threat to users' health. Moreover, cleaning the air outlet requires disassembling multiple parts, making the process cumbersome and increasing the cleaning burden on users.

[0006] Especially for body purifiers (primarily used in Southeast Asia and the Middle East), which use water to clean the body (e.g., anus) instead of paper towels, this method is considered more hygienic and thorough, reducing the incidence of anorectal diseases such as hemorrhoids. Water washing is not only a healthier choice but also more environmentally friendly, eliminating the need for large amounts of toilet paper and reducing deforestation and energy consumption and pollution in paper production. Existing body purifiers not only have water spraying but also blowing functions, but their air outlet design still follows a traditional pattern. On the one hand, the fixed and exposed air outlet makes the overall appearance of the body purifier less aesthetically pleasing and refined, difficult to integrate with modern home décor, and reduces the product's market competitiveness. On the other hand, in terms of space utilization, the prominent air outlet limits the use and placement of body purifiers in small spaces such as bathrooms, causing inconvenience to users. Furthermore, in terms of dust prevention and cleaning, the exposed air outlet easily accumulates moisture, dirt, and bacteria in the bathroom, affecting the blowing effect and potentially harming the user's health. The complicated cleaning process also deters users.

[0007] Therefore, the inventors dedicated themselves to designing an air outlet structure and a body cleaning handle to solve the above problems. Utility Model Content

[0008] The purpose of this utility model is to provide a concealed air outlet structure, in which the air outlet can be hidden inside the housing when not in use, which not only improves the aesthetics and space utilization of the product, but also prevents dust and facilitates cleaning.

[0009] Another objective of this utility model is to provide a body cleaning handle that can achieve water spraying and air drying functions on the same handle, while concealing the air outlet. This not only improves the aesthetic appearance and space utilization of the handle, but also facilitates dust prevention and cleaning, making it convenient for users.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] A concealed air outlet structure is provided, wherein the housing is provided with an air inlet hole, and an air outlet bracket is slidably inserted into the air outlet end face of the housing along the axial direction of the housing. The side part of the air outlet bracket is hollowed out. When the air outlet bracket extends out of the housing under the drive of the air pressure inside the housing, the hollowed-out part of its side and the edge of the air outlet end of the housing form an air outlet.

[0012] As an improvement of the concealed air outlet structure of this utility model, an air outlet groove is provided on the outer wall of the air outlet frame along its axial direction, and an air outlet slide is provided on the inner wall of the housing along its axial direction. The air outlet slide and the air outlet groove are matched for limiting.

[0013] As an improvement of the concealed air outlet structure of this utility model, the air outlet frame is sealed to the housing through a sealing ring, and the sealing ring is sleeved outside the air outlet frame and located inside the housing.

[0014] As an improvement of the concealed air outlet structure of this utility model, the air outlet frame is elastically connected to the housing through multiple air outlet springs. Each air outlet spring is arranged along the axial direction of the housing and its two ends are respectively connected to the air outlet frame and the housing.

[0015] As an improvement of the concealed air outlet structure of this utility model, the housing is provided with a fan for pushing the air outlet frame to extend and expel air from the air outlet. The end face of the air outlet frame facing the fan is hollowed out, and the inner wall of the air outlet frame and the hollowed-out part on its side are provided with an arc-shaped air guide surface.

[0016] To achieve the aforementioned other objective, the technical solution adopted by this utility model is as follows:

[0017] A body cleaning handle includes a nozzle, a flow valve, and the aforementioned concealed air outlet structure. The nozzle is mounted on the side wall of the housing and is located on the same side as the air outlet. The flow valve is located inside the housing and communicates with the nozzle's spray hole.

[0018] As an improvement to the body cleaning handle of this utility model, the nozzle has an angle adjustment function and is hinged to the housing. The pressing surface of the nozzle is exposed in the housing, and the spray hole is located on the pressing surface of the nozzle.

[0019] As an improvement of the body cleaning handle of this utility model, the nozzle is installed in the mounting hole on the side wall of the housing, and an angle adjustment block is elastically connected to the side wall of the mounting hole. The side wall of the nozzle is provided with multiple angle adjustment slots, and the angle adjustment block cooperates with the multiple angle adjustment slots respectively to realize the adjustment of different spray angles of the nozzle.

[0020] As an improvement of the body cleaning handle of this utility model, the nozzle is sealed to the housing through a sealing assembly. The nozzle is located inside the sealing assembly. The nozzle connector passes through the bottom of the sealing assembly and is connected to the flow valve through the water outlet pipe. The flexible part at the bottom of the sealing assembly has a V-shaped cross-section and is arranged in a circle around the connector.

[0021] As an improvement of the body cleaning handle of this utility model, the housing includes a housing body and an adjusting cover. The air outlet and the adjusting cover are respectively located at the air outlet end and water inlet end of the housing body. The adjusting cover is magnetically attached to the housing body and is slidably connected to the housing body along the axial direction of the housing body. A dustproof steel mesh is provided in the housing body at a position corresponding to the adjusting cover. The air inlet is located on the adjusting cover and communicates with the interior of the housing body through the dustproof steel mesh.

[0022] Compared with the prior art, the concealed air outlet structure of this utility model slides the air outlet frame along the axial direction of the housing onto the air outlet end face of the housing. The side part of the air outlet frame is hollowed out. When the air outlet frame is extended, the hollowed-out part on its side and the edge of the air outlet end of the housing form an air outlet. At the same time, a fan is provided inside the housing to push the air outlet frame to extend and exhaust air from the air outlet. This allows the air outlet to be hidden inside the housing when not in use, improving the product's aesthetics and space utilization, and making it easy to prevent dust, water and cleaning.

[0023] Compared with existing technologies, the body cleaning handle of this utility model combines a nozzle, a flow valve, and the aforementioned concealed air outlet structure to form a body cleaning handle. In this handle, the nozzle is installed on the side wall of the housing and is located on the same side as the air outlet. The flow valve is located inside the housing and communicates with the nozzle's spray hole, allowing users to achieve water spraying for cleaning and air drying functions on the same handle. The flow valve can precisely control the water flow, improving the cleaning effect and saving water resources. At the same time, the application of the concealed air outlet structure hides the air outlet of the handle, which not only improves the handle's appearance and space utilization, but also facilitates dustproofing, waterproofing, and cleaning, providing users with a higher quality and more convenient body cleaning handle for ease of use.

[0041] The embodiments of this utility model are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model.

[0042] Reference Figures 1 to 10 A concealed air outlet structure includes a housing 1, an air outlet frame 2, and a fan 5. The housing 1 is provided with an air inlet 131. The air outlet frame 2 is slidably inserted into the air outlet end face of the housing 1 along the axial direction of the housing 1. The side part of the air outlet frame 2 is hollowed out. When the air outlet frame 2 is extended, its hollowed-out side part and the edge of the air outlet end of the housing 1 form an air outlet 25. The fan 5 is set inside the housing 1 to generate wind pressure inside the housing 1. The wind pressure generated by the fan 5 can drive the air outlet frame 2 to extend out of the housing 1 and exhaust air from the air outlet 25.

[0043] Reference Figures 1 to 3 The housing 1 is cylindrical in shape and hollow inside. One end of the housing 1 is its air outlet and its end face is open. The other end of the housing 1 is its air inlet. The air inlet hole 131 is located at the air inlet of the housing 1. The fan 5 is located between the air outlet frame 2 and the air inlet hole 131. The inner wall of the air outlet of the housing 1 is provided with multiple long strip-shaped air outlet slides 114 along its axial direction. All the air outlet slides 114 are located at the air outlet opening of the housing 1. Multiple first connecting columns 111 are vertically provided on the inner wall of the air outlet of the housing 1.

[0044] Reference Figure 4 , Figure 5 , Figure 6 and Figure 9 The air outlet frame 2 is cylindrical, with a hollowed-out end face facing the fan 5. Multiple elongated air outlet grooves 22 are provided along the axial direction of the outer wall of the air outlet frame 2. All air outlet slides 114 correspond to and are positioned within each air outlet groove 22, allowing the air outlet frame 2 to slide along the axial direction of the housing 1. Multiple second connecting posts 21 are vertically arranged on the inner wall of the air outlet frame 2. The air outlet frame 2 is elastically connected to the housing 1 via multiple air outlet springs 24. Specifically, each air outlet spring 24 is arranged along the axial direction of the housing 1, and its two ends are respectively connected to the second connecting posts 21 on the inner wall of the air outlet frame 2. The connecting post 21 is connected to the first connecting post 111 on the inner wall of the housing 1 (the two ends of the air outlet spring 24 are respectively sleeved on the first connecting post 111 and the second connecting post 21) so that when the fan 5 is not working, the air outlet frame 2 can be hidden inside the housing 1 under the pull of multiple air outlet springs 24. In order to prevent external water from entering the housing 1 from the air outlet frame 2, the air outlet frame 2 is sealed to the housing 1 through an annular sealing ring 23. The sealing ring 23 is sleeved on the outside of the air outlet frame 2 and located inside the housing 1. The inner wall of the air outlet frame 2 is provided with an arc-shaped air guide surface 26 at the position opposite to the hollow part on its side.

[0045] Reference Figures 1 to 10 The working principle of the concealed air outlet structure of this utility model is as follows:

[0046] Initial state (air vent 25 hidden):

[0047] In its initial state, the air outlet frame 2 is in a retracted position along the axial direction of the housing 1, completely retracted into the housing 1. At this time, the hollowed-out part on the side of the air outlet frame 2 is blocked by the edge of the air outlet end of the housing 1, and cannot communicate with the outside air, and the air outlet 25 is in a hidden state;

[0048] Airflow process:

[0049] When airflow is needed, the fan 5 starts working, rotating at high speed inside the housing 1 to generate strong suction, drawing outside air into the housing 1 through the air inlet 131. As air is continuously drawn in, the air pressure inside the housing 1 gradually increases, creating a pressure difference. Under this pressure difference, the air outlet frame 2 slides outward along the axial direction of the housing 1, and the air outlet spring 24 extends. As the air outlet frame 2 extends, the hollowed-out portion on its side, which was originally covered by the edge of the air outlet end of the housing 1, is gradually exposed, forming an air outlet 25 together with the edge of the air outlet end of the housing 1. At this time, the air drawn in and pressurized by the fan 5 inside the housing 1 is guided by the air guide surface 26 on the inner wall of the air outlet frame 2, and ejected at high speed through the hollowed-out portion on the side of the air outlet frame 2 from the newly formed air outlet 25, thus achieving the airflow function.

[0050] End of airflow and reset:

[0051] When the air supply demand ends, the fan 5 stops working, and there is no longer a continuous suction and pressure difference inside the housing 1. At this time, under the pulling action of the air outlet spring 24 of the air outlet frame 2, it slides inward along the axial direction of the housing 1 and retracts back into the housing 1. As the air outlet frame 2 retracts, the hollow part on its side is once again blocked by the edge of the air outlet end of the housing 1, the air outlet 25 is hidden again, the structure returns to its initial state, and it waits for the next air supply command.

[0052] The concealed air outlet structure of this utility model involves sliding the air outlet frame 2 along the axial direction of the housing 1 onto the air outlet end face of the housing 1. The side of the air outlet frame 2 is hollowed out. When the air outlet frame 2 is extended, the hollowed-out side and the edge of the air outlet end of the housing 1 form an air outlet 25. At the same time, the housing 1 is equipped with a fan 5 for pushing the air outlet frame 2 to extend and for air to be discharged from the air outlet 25. This allows the air outlet 25 to be hidden inside the housing 1 when not in use, improving the product's aesthetics and space utilization, and facilitating dust prevention and cleaning.

[0053] Reference Figures 1 to 15 A body cleaning handle includes a nozzle 3, a flow valve 6, and the aforementioned concealed air outlet structure. The nozzle 3 is mounted on the side wall of the housing 1 and is located on the same side as the air outlet 25. The flow valve 6 is located inside the housing 1 and communicates with the nozzle 3's spray hole.

[0054] Reference Figures 1 to 5The housing 1 includes a housing body 14 and an adjusting cover 13. The two ends of the housing body 14 are the air outlet and the water inlet, respectively. The air outlet bracket 2 and the adjusting cover 13 are located at the air outlet and water inlet of the housing body 14, respectively. The housing body 14 includes a lower shell 12, an upper shell 11, and a fixing bracket 81. The upper shell 11 is cylindrical. All the first connecting posts 111 and all the air outlet slide strips 114 are located on the inner wall of the upper shell 11. The air outlet bracket 2 is slidably inserted into the air outlet of the upper shell 11. A mounting hole 113 is provided on the side wall of the air outlet of the upper shell 11. The inner side wall of the mounting hole 113... The upper shell 11 has a side hole 112, and the side wall of the upper shell 11 is hollowed out. The lower shell 12 is semi-circular and covers the hollowed-out part of the side wall of the upper shell 11 to form a cylinder. The fixing frame 81 is cylindrical and each wall is hollowed out. The entire fixing frame 81 is fixed to the water inlet end face of the upper shell 11 (the fixing frame 81 is located outside the upper shell 11). A ring-shaped second magnetic ring 812 is fixed on the end face of the fixing frame 81 away from the air outlet frame 2. Multiple long strip-shaped adjusting slides 811 are arranged radially on the outer side wall of the fixing frame 81 (the part that is not hollowed out). A dustproof steel mesh is fixed inside the fixing frame 81. 8. The dustproof steel mesh 8 has a hollowed-out end face near the air outlet frame 2. The side walls and the end walls away from the air outlet frame 2 of the dustproof steel mesh 8 are both mesh-like. The adjusting cover 13 is cylindrical and has a hollowed-out end face near the air outlet frame 2. A first annular magnetic ring 132 is fixed on the inner bottom wall of the adjusting cover 13. The position of the first magnetic ring 132 is opposite to the position of the second magnetic ring 812, so that the adjusting cover 13 magnetically covers the shell body 14. When the adjusting cover 13 is fitted onto the fixing frame 81, the second magnetic ring 812 on the fixing frame 81 magnetically attracts the first magnetic ring 132 inside the adjusting cover 13. The inner wall of the adjusting cover 13 is provided with multiple elongated adjusting grooves 133 along its axial direction. All adjusting grooves 133 correspond to all adjusting strips 811, so that the adjusting cover 13 can slide along the axial direction of the shell body 14 and be slidably connected to the shell body 14. The side wall of the adjusting cover 13 and its end face away from the air outlet frame 2 are provided with air inlet holes 131. A dustproof steel mesh 8 is provided in the shell body 14 at the corresponding position of the adjusting cover 13 (i.e., a dustproof steel mesh 8 is provided in the fixing frame 81), so that the adjusting cover 13 can communicate with the interior of the shell body 14 through the dustproof steel mesh 8.

[0055] Reference Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12The nozzle 3 has an angle adjustment function. The nozzle 3 is block-shaped, and hinge posts 36 are provided on two corresponding sides of the nozzle 3. The nozzle 3 is installed in the mounting hole 113 of the upper shell 11. The nozzle 3 is hinged to the two opposite side walls of the mounting hole 113 through the two hinge posts 36. The pressing surface of the nozzle 3 is exposed on the shell 1. The pressing surface of the nozzle 3 has multiple spray holes, specifically a first spray hole 31 and a row of second spray holes 32. The diameter of the first spray hole 31 is larger than the diameter of the second spray hole 32. The nozzle 3 has an inner cavity 321. Two connectors 34 are provided on the side of the nozzle 3 away from its pressing surface. One of the connectors 34 is coaxially connected to the first spray hole 31, and the other connector 34 is connected to a row of second spray holes 32 through the inner cavity 321. The nozzle 3 has multiple angle adjustment grooves 33 arranged radially along the housing 1 on the side wall near the side hole 112. An angle adjustment block 35 is elastically connected to the side hole 112 on the side wall of the mounting hole 113 through an angle adjustment spring 351. The angle adjustment block 35 cooperates with multiple angle adjustment grooves 33 to realize the adjustment of different spray angles of the nozzle 3. In this embodiment, three angle adjustment grooves 33 are preferred so that the nozzle 3 can be adjusted to 70 degrees, 90 degrees and 110 degrees.

[0056] Reference Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12 The nozzle 3 is sealed to the housing 1 via a sealing assembly 4. The sealing assembly 4 is open on the side near the mounting hole 113, and the nozzle 3 is located inside the sealing assembly 4. The sealing assembly 4 includes a sealing sleeve 41 and a sealing diaphragm 42. The sealing sleeve 41 is annular and fits over the side wall of the mounting hole 113. When the side hole 112 is a through hole, the sealing sleeve 41 fits over the outer wall of the mounting hole 113 to form the bottom of the side hole 112. The two ends of the angle adjusting spring 351 are connected to the sealing sleeve 41 and the angle adjusting block 35, respectively. The sealing diaphragm 42 is a fixed cover. The bottom of the sealing assembly 4 is formed on the sealing sleeve 41. The cross-section of the sealing diaphragm 42 is V-shaped, forming a flexible part 421. Two connectors 34 pass through the sealing diaphragm 42 and extend outside the sealing diaphragm 42. The entire flexible part 421 is arranged in a circle around the two connectors 34. The flexible part 421 forms the pleated part of the sealing diaphragm 42 to enhance the flexibility of the sealing diaphragm 42. When the nozzle 3 is adjusted to an angle, the flexible part 421 also adjusts adaptively with the change of the angle of the connectors 34, thereby improving the sealing performance of the nozzle 3 at the two connectors 34.

[0057] Reference Figure 4 , Figure 5 , Figure 8 , Figure 13 , Figure 14 and Figure 15The housing 1 also contains a PCBA board 7, which has a Hall sensor 71 and a switch. The fan 5 is electrically connected to the PCBA board 7. The fan 5 is located between the air outlet frame 2 and the flow valve 6. The flow valve 6 includes a valve body 61 and an adjusting ring 62. The two water outlet pipes 614 of the valve body 61 are respectively connected to two connectors 34. The water inlet pipe 613 of the valve body 61 and the power cord of the fan 5 are covered by the same insulating outer layer and pass through the adjusting ring 62, the dustproof steel mesh 8, the fixing frame 81, and the adjusting cover 13 in sequence. They extend from the end face of the adjusting cover 13 to the outside of the entire housing 1 for connection with the external water system. The end face of the valve body 61 facing the adjusting ring 62 has an insertion groove 611. The side wall of the insertion groove 611 has three gear adjustment grooves 612 of different widths. The adjusting ring 62 is located between the fixing frame 81 and the valve body 61, and the adjusting ring 62 faces the valve body 61. An L-shaped adjusting rod 621 is provided at the edge of one end face. The end of the adjusting rod 621 extends into the insertion groove 611. A gear adjusting block 623 is elastically connected to the groove on the side wall of the insertion end (i.e., the end) of the adjusting rod 621 through a gear adjusting spring 6231. When the insertion end of the adjusting rod 621 is inserted into the insertion groove 611, the gear adjusting block 623 is located in one of the gear adjusting slots 612. The gear adjusting block 623 can control the water spraying of different nozzles by being located in different gear adjusting slots 612. A Hall magnet 622 is provided at the end of the adjusting rod 621 near the adjusting ring 62. The Hall sensor 71 can sense the change in the magnetic field of the Hall magnet 622, thereby capturing the position of the adjusting ring 62 and controlling the opening and closing of the fan 5. When the adjusting ring 62 rotates, the adjusting ring 62 drives the adjusting rod 621 to rotate, which can not only adjust the water spraying mode of the flow valve 6, but also control the opening and closing of the fan 5.

[0058] The working principle of the body cleaning handle of this utility model is as follows:

[0059] Water from the external water system enters the flow valve 6 through the inlet pipe 613;

[0060] Pressing the switch causes the adjusting ring 62 and the adjusting rod 621 to rotate together. The gear adjusting block 623 on the adjusting rod 621 switches between the three gear adjusting slots 612. When the gear adjusting block 623 is in one of the gear adjusting slots 612, the flow valve 6 controls the water outlet pipe 614 connected to the first spray hole 31 to open, so that the first spray hole 31 sprays water. When the gear adjusting block 623 is in another gear adjusting slot 612, the flow valve 6 controls the water outlet pipe 614 connected to the second spray hole 32 to open, so that all four second spray holes 32 spray water. When the gear adjusting block 623 is in the third gear adjusting slot 612, the flow valve 6 controls the two water outlet pipes 614 to open, so that the first spray hole 31 and the four second spray holes 32 spray water together. The user can select the appropriate amount of water spray according to actual needs.

[0061] When the spray angle of nozzle 3 needs to be adjusted to 70 degrees, manually press the side of nozzle 3 closest to the air outlet frame 2, causing nozzle 3 to rotate 20 degrees counterclockwise to a tilted state. The side of nozzle 3 away from the air outlet frame 2 will tilt up, and at this time, the angle adjustment block 35 will be located in the uppermost angle adjustment groove 33. When the spray angle of nozzle 3 needs to be adjusted to 90 degrees (i.e., the spray direction is perpendicular to the side wall of housing 1), press nozzle 3 again to make nozzle 3 flush with the side wall of housing 1, and the angle adjustment block 35 will switch to the middle angle adjustment groove 33. When the spray angle of nozzle 3 needs to be adjusted to 110 degrees, manually press the side of nozzle 3 away from the air outlet frame 2, causing nozzle 3 to rotate 20 degrees clockwise to a tilted state. The side of nozzle 3 closest to the air outlet frame 2 will tilt up, and at this time, the angle adjustment block 35 will be located in the lowermost angle adjustment groove 33.

[0062] After cleaning, press the switch again to rotate the adjusting ring 62, turning on the fan 5. The fan 5 rotates at high speed inside the housing 1, generating a strong suction force that draws outside air into the housing 1 through the air inlet 131. As air is continuously drawn in, the air pressure inside the housing 1 gradually increases, creating a pressure difference. Under this pressure difference, the air outlet frame 2 slides outward along the axial direction of the housing 1, and the air outlet spring 24 extends. As the air outlet frame 2 extends, the hollowed-out part on its side, which was originally covered by the edge of the air outlet end of the housing 1, is gradually exposed, forming an air outlet 25 together with the edge of the air outlet end of the housing 1. At this time, the air drawn in and pressurized by the fan 5 inside the housing 1 is guided by the air guide surface 26 on the inner wall of the air outlet frame 2, and ejected at high speed through the hollowed-out part on the side of the air outlet frame 2 through the newly formed air outlet 25, thus realizing the air outlet function.

[0063] When the air supply demand ends, the fan 5 stops working, and there is no longer a continuous suction and pressure difference inside the housing 1. At this time, under the pulling action of the air outlet spring 24 of the air outlet frame 2, it slides inward along the axial direction of the housing 1 and retracts back into the housing 1. As the air outlet frame 2 retracts, the hollow part on its side is once again blocked by the edge of the air outlet end of the housing 1, the air outlet 25 is hidden again, the structure returns to its initial state, and it waits for the next air supply command.

[0064] When it is necessary to clean the dustproof steel mesh 8, simply pull the adjusting cover 13 outward along the axial direction of the housing 1 to remove the adjusting cover 13. After the dustproof steel mesh 8 is cleaned, put the adjusting cover 13 back on along the axial direction of the housing 1. The adjusting cover 13 can then be magnetically connected to the second magnetic ring 812 on the fixing frame 81 through the first magnetic ring 132 inside it.

[0065] This utility model of a body cleaning handle combines a nozzle 3, a flow valve 6, and the aforementioned concealed air outlet structure to form a body cleaning handle. In this handle, the nozzle 3 is installed on the side wall of the housing 1 and is located on the same side as the air outlet 25. The flow valve 6 is located inside the housing 1 and communicates with the spray hole of the nozzle 3, allowing users to achieve water spraying and air drying functions on the same handle. The flow valve 6 can precisely control the water flow, improving the cleaning effect and saving water resources. At the same time, the application of the concealed air outlet structure hides the air outlet 25 of the handle, which not only improves the appearance and space utilization of the handle, but also facilitates dustproofing, waterproofing, and cleaning, providing users with a higher quality and more convenient body cleaning handle for user convenience.

[0066] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
