Abstract
Description
Technical Field
[0001] This utility model relates to the field of skin care technology, and more specifically, to a skin care device. Background Technology
[0002] In the skin care process of medical aesthetic institutions, before performing minimally invasive treatments or other skin care procedures, it is necessary to use a spray bottle to spray disinfectant to disinfect the treatment area. The spray nozzle needs to be changed frequently according to different care procedures and patients' skin conditions to achieve different care functions and meet different medication needs. However, most of the skin care devices currently used in clinical practice adopt traditional threaded or snap-on connection methods. When medical staff change the spray nozzle, they need to rotate or press it forcefully repeatedly. This is not only cumbersome and time-consuming, but also prone to leakage of medicine due to improper sealing, which affects the care effect and hygiene safety.
[0003] With the diversification of skin care programs, higher demands are placed on the convenience and safety of care devices. In particular, when multiple care programs need to be performed consecutively, the drawbacks of traditional connection methods become more apparent. Frequent replacement of nozzles by medical staff not only increases workload but also prolongs care time and reduces work efficiency. At the same time, repeated installation and disassembly can easily cause wear and tear on connecting parts, affecting the service life and sealing performance of the device. Improper connection may even lead to waste and contamination of care solution. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the problems existing in the prior art, this utility model provides a skin care device to solve the technical problem mentioned in the background art that medical staff need to repeatedly rotate or forcefully press when changing the nozzle, which is not only cumbersome and time-consuming, but also prone to leakage of medicine due to improper sealing, affecting the care effect and hygiene safety.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a skin care device, comprising a bottle body, a spray nozzle connected to the bottle body, and a spray head connected to the spray head via a quick-release mechanism. The quick-release mechanism includes a quick-release sleeve, a locking block, a tube, a slot, a locking sleeve, and a quick-release mechanism. The quick-release sleeve is installed on the spray head, the locking block has multiple sets that slide on the outer wall of the quick-release sleeve, the tube is installed on the spray head, the slot has multiple sets distributed on the outer wall of the tube, the locking sleeve is connected to the outer wall of the quick-release sleeve, and the quick-release mechanism... The device includes a movable sleeve, a ramp surface, and abutment blocks. The movable sleeve is installed on the top of the locking sleeve. Multiple sets of ramp surfaces are provided on the outside of the movable sleeve. Multiple sets of abutment blocks are provided on the outside of multiple sets of locking blocks. The outer wall of the quick-release sleeve is provided with a limiting mechanism. The limiting mechanism includes a limiting block, a limiting groove, a limiting sleeve, and a push spring. Multiple sets of limiting blocks slide on the outer wall of the movable sleeve. Multiple sets of limiting grooves are distributed on the outer wall of the quick-release sleeve. The limiting sleeve is provided on the outer wall of the quick-release sleeve. The two ends of the push spring are connected to the quick-release sleeve and the limiting sleeve, respectively.
[0008] The present invention is further provided that a sealing ring is installed at the top of the insertion tube. The sealing ring ensures the sealing between the insertion tube and the quick-release sleeve, effectively preventing leakage of nursing liquid or entry of external contaminants during use, improving the hygiene and safety of the device, and also extending the service life of the device.
[0009] The present invention is further configured such that each of the multiple sets of card blocks has an inclined surface on its outer side, and each of the multiple sets of inclined surfaces abuts against the locking sleeve. The inclined surface design on the outer side of the card block cooperates with the abutment of the locking sleeve, generating an inward component force when the locking sleeve is pressed down, so that the card block is more firmly embedded in the card slot, enhancing the connection firmness, and also making it easier for the card block to smoothly disengage from the card slot when needed, thereby improving the reliability and ease of operation of the device.
[0010] The present invention is further configured such that the spacing between the multiple sets of slots is set to be equal. The equally distributed slot design ensures that the insertion tube is subjected to uniform force in the quick-release sleeve, which improves the stability and reliability of the connection. At the same time, it simplifies the manufacturing process, facilitates standardized production, and reduces production costs.
[0011] The present invention is further configured such that the bottom ends of the multiple sets of abutment blocks are all arc-shaped. The arc-shaped design reduces the contact friction between the abutment blocks and the slope surface, making the movable sleeve rotate more smoothly, reducing operating resistance, improving the convenience of disassembly, and also reducing wear between parts and extending the service life of the device.
[0012] The present invention is further configured such that a return spring is installed at the top of each of the multiple sets of limiting blocks, and the bottom of each of the multiple sets of return springs is connected to the outer wall of the movable sleeve. The setting of the return springs enables the limiting blocks to automatically spring back to the limiting position, ensuring the reliability of the limiting function. The uniform distribution of multiple sets of return springs provides a stable limiting force, preventing the movable sleeve from rotating accidentally during use and improving the safety of the device.
[0013] The present invention is further configured such that a fixing ring is installed at the bottom of the quick-release sleeve, and the top of the push spring is connected to the fixing ring. The fixing ring provides a stable support point for the push spring, ensuring the uniform distribution of the push spring force. The connection design between the push spring and the fixing ring makes the operation of the limiting sleeve more flexible and facilitates the user to quickly release the limit.
[0014] The present invention is further configured such that the diameter of the fixing ring is the same as the inner diameter of the nozzle. This design ensures the coaxiality of the nozzle and the quick-release sleeve, improves the accuracy and stability of the connection, and also prevents the nozzle from shaking during use, thereby improving the accuracy and comfort of the nursing process.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a skin care device with the following beneficial effects:
[0017] 1. The quick-release mechanism achieves rapid nozzle positioning by setting a quick-release sleeve on the spray nozzle and multiple sets of sliding locking blocks on the outer wall of the quick-release sleeve, in conjunction with multiple sets of equidistant slots on the outer wall of the insertion tube. The abutment design of the locking sleeve and the outer inclined surface of the locking block can generate stable inward pressure to ensure that the locking block is firmly embedded in the slot. The sealing ring at the top of the insertion tube and the fixing ring at the bottom not only ensure the sealing of the connection, but also ensure the coaxiality of the nozzle, solving the problems of unstable connection and poor sealing in the existing technology, and greatly improving the reliability and safety of the nursing device.
[0018] 2. The quick-release mechanism adopts an innovative design with a movable sleeve, a ramp surface, and a stop block. The longitudinal sliding of the movable sleeve can release the lock sleeve from restricting the block. Then, by rotating the movable sleeve, the clever cooperation between the ramp surface and the stop block converts the rotational motion into the radial movement of the block. The arc-shaped design at the bottom of the stop block reduces the frictional resistance with the ramp surface, making the entire disassembly process smoother. This overcomes the shortcomings of traditional devices, such as laborious disassembly and low efficiency, and realizes quick and convenient disassembly of the nozzle.
[0019] 3. The limiting mechanism, by setting a limiting groove on the outer wall of the quick-release sleeve, together with the limiting block and return spring on the outer wall of the movable sleeve, forms a reliable limiting system. The design of the limiting sleeve and push spring makes the release operation of the limit simple and intuitive. Simply push the limiting sleeve to release the limiting block through the compression of the push spring, thereby releasing the restriction on the movable sleeve. This design not only ensures the stability of the device during use and prevents the movable sleeve from rotating accidentally, but also does not affect the quick disassembly and assembly when necessary, thus improving the operational safety and ease of use of the entire nursing device.

[0029] Please see Figures 1-5 A skin care device includes a bottle body 1, a spray head 2 connected to the bottle body 1, and a spray nozzle 3 connected to the spray head 2 via a quick-release mechanism. The quick-release mechanism includes a quick-release sleeve 4, a locking block 5, an insert 6, a locking groove 7, a locking sleeve 8, and a quick-release mechanism. The quick-release sleeve 4 is installed on the spray head 2. The locking block 5 has multiple sets that slide on the outer wall of the quick-release sleeve 4. The insert 6 is installed on the spray nozzle 3. The locking groove 7 has multiple sets distributed on the outer wall of the insert 6. The locking sleeve 8 is connected to the outer wall of the quick-release sleeve 4. The quick-release mechanism includes a movable sleeve 9, a ramp surface 10, and an abutment block 11. The movable sleeve 9 is installed on the top of the locking sleeve 8. The inclined surface 10 is provided with multiple sets of movable sleeve 9 on the outside. The abutting block 11 is provided with multiple sets of abutting blocks 5 respectively installed on the outside of multiple sets of locking blocks 5. The outer wall of the quick-release sleeve 4 is provided with a limiting mechanism, which includes a limiting block 12, a limiting groove 13, a limiting sleeve 14 and a push spring 15. The limiting block 12 is provided with multiple sets of sliding on the outer wall of the movable sleeve 9. The limiting groove 13 is provided with multiple sets distributed on the outer wall of the quick-release sleeve 4. The limiting sleeve 14 is provided on the outer wall of the quick-release sleeve 4. The two ends of the push spring 15 are respectively connected to the quick-release sleeve 4 and the limiting sleeve 14.
[0030] A sealing ring 16 is installed at the top of the cannula 6. When the cannula 6 is inserted into the quick-release sleeve 4, the sealing ring 16 fits tightly against the inner wall of the quick-release sleeve 4. The elastic deformation characteristics of the sealing ring 16 create a sealing pressure between the contact surfaces, thereby preventing leakage of nursing fluid and the entry of external contaminants.
[0031] Each set of locking blocks 5 has an inclined surface 17 on its outer side. Each set of inclined surfaces 17 abuts against the locking sleeve 8. When the locking sleeve 8 moves downward, its inner wall generates a squeezing force with the inclined surface 17 on the outer side of the locking block 5. Due to the inclined design of the inclined surface 17, this axial pressure is converted into a radial component force, which pushes the locking block 5 to move inward and embed into the locking groove 7, thereby achieving a reliable locking effect.
[0032] The spacing between the multiple sets of slots 7 is set to be equal. This equidistant design ensures that the radial force on the insertion tube 6 is evenly distributed within the quick-release sleeve 4. When multiple sets of blocks 5 are simultaneously inserted into the slots 7, each block 5 bears equal stress, avoiding local stress concentration and ensuring the stability and reliability of the connection.
[0033] The bottom ends of multiple sets of abutment blocks 11 are all set to be arc-shaped. When the movable sleeve 9 rotates, its outer slope surface 10 contacts the arc-shaped bottom end of the abutment block 11. This arc design changes the contact mode of the two surfaces from surface contact to point contact or line contact, which significantly reduces the contact area and frictional resistance.
[0034] Each of the multiple sets of limiting blocks 12 is equipped with a return spring 18 at its top. The bottom of each set of return springs 18 is connected to the outer wall of the movable sleeve 9. The return spring 18 always provides an inward elastic force to the limiting block 12. When the limiting block 12 is aligned with the limiting groove 13, it automatically embeds into the limiting groove 13 under the action of the return spring 18, thus realizing a reliable limiting function.
[0035] The quick-release sleeve 4 is equipped with a fixing ring 19 at the bottom. The top of the push spring 15 is connected to the fixing ring 19. The push spring 15 forms a stable connection with the quick-release sleeve 4 through the fixing ring 19. When it is necessary to release the limit, push the limit sleeve 14 to compress the push spring 15, so that the limit sleeve 14 temporarily releases the limit block 12, realizing a flexible limit release operation.
[0036] The diameter of the retaining ring 19 is the same as the inner diameter of the nozzle 3. This size matching design allows the nozzle 3 to be accurately aligned during installation. The retaining ring 19 plays a guiding and positioning role, ensuring that the nozzle 3 and the quick-release sleeve 4 remain coaxial, avoiding installation deviation and shaking during use.
[0037] In this embodiment, when the nozzle 3 needs to be installed, the insertion tube 6 is inserted into the quick-release sleeve 4. Multiple sets of slots 7 on the outer wall of the insertion tube 6 correspond to multiple sets of locking blocks 5 on the quick-release sleeve 4. Under the action of the locking sleeve 8, the outer inclined surface 17 of the locking block 5 abuts against the inner wall of the locking sleeve 8, generating inward pressure to embed the locking block 5 into the slot 7. The sealing ring 16 at the top of the insertion tube 6 ensures the sealing of the connection, while the design of the fixing ring 19 ensures the coaxiality of the nozzle 3. The design of multiple equidistantly distributed slots 7 provides uniform fixing force, achieving rapid and stable installation of the nozzle 3. When the nozzle 3 needs to be disassembled, the movable sleeve 9 is first slid longitudinally to release the locking sleeve 8 from the contact of the multiple sets of inclined surfaces 17. Then, the movable sleeve 9 is rotated so that the multiple sets of inclined surfaces 10 on its outer side contact the abutting block 11 on the outer side of the locking block 5. Since the bottom end of the abutting block 11 is designed with an arc shape, the sliding between it and the inclined surface 10 is smoother. As the movable sleeve 9 is rotated, the inclined surface 10 pushes the abutting block 11 to move the locking block 5 outward, so that the locking block 5 is disengaged from the slot 7, thereby releasing the lock on the insertion tube 6 and realizing the quick disassembly of the nozzle 3.
[0038] More specifically, when it is necessary to release the restriction of the limiting mechanism on the movable sleeve 9, the limiting sleeve is pushed to slide and squeeze the push spring 15, so that the limiting sleeve 14 releases its contact with the multiple sets of limiting blocks 12. The multiple sets of reset springs 18 push the limiting blocks 12 to move outward and disengage from the limiting groove 13, and then the restriction on the movable sleeve 9 can be released.
[0039] In summary, during use or operation of the overall equipment: when it is necessary to install the nozzle 3, insert the tube 6 into the quick-release sleeve 4. The multiple sets of slots 7 on the outer wall of the tube 6 correspond to the multiple sets of locking blocks 5 on the quick-release sleeve 4. Under the action of the locking sleeve 8, the outer inclined surface 17 of the locking block 5 abuts against the inner wall of the locking sleeve 8, generating inward pressure to make the locking block 5 embed into the slot 7. The sealing ring 16 at the top of the tube 6 ensures the sealing of the connection, while the design of the fixing ring 19 ensures the coaxiality of the nozzle 3. The design of multiple sets of equidistantly distributed slots 7 provides uniform fixing force, realizing the coaxiality of the nozzle 3. For quick and stable installation, when it is necessary to disassemble the nozzle 3, firstly, slide the movable sleeve 9 longitudinally to release the locking sleeve 8 from the contact of the multiple sets of inclined surfaces 17, and then rotate the movable sleeve 9 so that the multiple sets of inclined surfaces 10 on its outer side contact the abutting block 11 on the outer side of the locking block 5. Since the bottom end of the abutting block 11 adopts an arc-shaped design, the sliding between it and the inclined surface 10 is smoother. As the movable sleeve 9 rotates, the inclined surface 10 pushes the abutting block 11 to drive the locking block 5 to move outward, so that the locking block 5 is disengaged from the slot 7, thereby releasing the lock on the insertion tube 6 and realizing the quick disassembly of the nozzle 3.
[0040] When it is necessary to release the restriction of the limiting mechanism on the movable sleeve 9, push the limiting sleeve to slide and squeeze the push spring 15, so that the limiting sleeve 14 releases its contact with the multiple sets of limiting blocks 12. The multiple sets of reset springs 18 push the limiting blocks 12 to move outward and disengage from the limiting groove 13, and then the restriction on the movable sleeve 9 can be released.
[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
