Description

Technical Field

[0001] This utility model relates to the field of dental protection technology, specifically to a three-way spray gun anti-slip protection structure. Background Technology

[0002] In clinical dental treatment, the three-way spray gun is a commonly used instrument, mainly used for spraying water, air, or mist to clean and cool the treatment area. To prevent contamination from direct contact between the patient's saliva, rinsing solution, and other liquids during treatment, and to reduce the workload of subsequent cleaning and disinfection, a protective cover is usually placed over the three-way spray gun.

[0003] However, in practice, doctors need to wear gloves to hold the spray gun, which is covered with a protective sleeve. Since liquid splashes are inevitable during treatment, the surface of the protective sleeve and the doctor's gloves easily become stained with liquid, significantly reducing friction and making slippage more likely.

[0004] This slippage problem can make it difficult for doctors to hold the spray gun stably for extended periods (such as ten minutes), which not only affects the accuracy and efficiency of treatment procedures but also poses a risk of the spray gun accidentally slipping off, thus interfering with the normal treatment process and potentially causing unnecessary harm to the patient.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a three-way spray gun anti-slip protection structure.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A three-in-one spray gun anti-slip protection structure includes a spray gun, a water jet pipe, and a protective sleeve; The discharge end of the spray gun is connected to the water-air pipe. The protective sleeve is fitted over the outside of the spray gun and is tightly fitted to the water jet pipe. The outer surface of the protective sleeve is provided with an anti-slip area, and the anti-slip area is provided with anti-slip texture; The anti-slip area is aligned with the middle area of ​​the spray gun along its length.

[0008] The spray gun, water hose, and protective sleeve are existing components, and their specific arrangement can refer to existing designs. Preferably, the protective sleeve can be designed to conform to the shape of the spray gun and water hose, achieving a tight fit.

[0009] Operators (such as doctors) typically hold the spray gun in the middle. The anti-slip area on the outer surface of the protective sleeve is aligned with this middle area. The anti-slip area has anti-slip textures, which can contact the operator's hand or the glove worn on the outside of the hand (described below as the hand). This increases the friction between the protective sleeve and the operator's hand, reduces the risk of the spray gun slipping due to the protective sleeve shifting relative to the operator's hand, avoids affecting the operator's stable use of the spray gun, and reduces the risk of accidents caused by the spray gun slipping.

[0010] Taking the middle area as an example, this area has no fixed range; it can be a 7-centimeter-long area or an 8-centimeter-long area. The middle area is only compared with the end area of ​​the spray gun (such as the discharge end).

[0011] In a further technical solution, the anti-slip texture is provided in multiple forms; In the unfolded state of the protective sleeve, the anti-slip patterns are spaced apart on the circumferential direction of the protective sleeve.

[0012] "Multiple" means at least two.

[0013] The anti-slip patterns can be evenly spaced, with no limit on the spacing. The distribution range of the anti-slip patterns along the circumference of the protective cover is also unrestricted.

[0014] The unfolded state of the protective cover refers to the state in which the protective cover is not retracted and is tightly fitted to the spray gun.

[0015] In this section, the anti-slip textures on the circumferential direction of the protective cover can achieve uniform coverage of friction in the hand grip area, promoting a balanced anti-slip effect in all areas of the contact surface between the operator's hand and the anti-slip area.

[0016] In a further technical solution, the anti-slip texture is provided in multiple forms; In the unfolded state of the protective sleeve, the anti-slip patterns are spaced apart along the length of the protective sleeve. With the protective cover in a tight fit, all the anti-slip patterns surround the spray gun.

[0017] The anti-slip patterns can be evenly spaced.

[0018] The protective cover being in a tight fit refers to the protective cover being folded up to fit snugly against the spray gun.

[0019] With the protective cover unfolded, depending on the specific design, each anti-slip pattern can be considered as a circular pattern (preferably) or an arc-shaped pattern. For example, without considering the multi-segment design of the anti-slip pattern, the anti-slip pattern can be either circular or arc-shaped.

[0020] In this section, the texture direction can be considered as the extension direction perpendicular to the protective case. The texture direction matches the radial gripping force direction of the hand, which can effectively improve the friction when pinching and gripping, and has a prominent anti-slip effect when the main operation scenario is fixed grip.

[0021] In some embodiments, when the protective cover is unfolded, some anti-slip patterns are spaced apart in the circumferential direction of the protective cover, and other anti-slip patterns are spaced apart in the longitudinal direction of the protective cover.

[0022] A further technical solution is that the anti-slip texture includes multiple sequentially connected anti-slip segments, and at least some of the anti-slip segments belonging to the same anti-slip texture are arranged in opposite directions.

[0023] The anti-slip texture may include three anti-slip sections, wherein the two anti-slip sections at both ends extend in the same direction and are set in a different direction from the anti-slip section in the middle.

[0024] Here, we'll use an example of anti-slip texture consisting of a single vertical segment and a single slanted segment to help you understand: When the vertical texture (vertical segment) and the slanted texture (slanted segment) are designed to connect, the two textures complement each other, covering the main lateral and diagonal force directions during gripping. The vertical texture primarily resists lateral sliding, while the slanted texture specifically addresses diagonal sliding and torsional forces. The two connect to form a continuous friction interface, ensuring that there is always a corresponding texture providing stable friction when the hand makes small displacements or changes in force direction. This avoids the failure of anti-slip in a single-direction texture in non-primary force directions, thereby improving the overall reliability and comprehensiveness of anti-slip.

[0025] In a further technical solution, each of the aforementioned anti-slip sections is arc-shaped.

[0026] Here, we will use an example of an anti-slip texture consisting of two arc-shaped segments to help with understanding: With the design of two arc-shaped textures (anti-slip segments), the arc direction can be set according to the natural curling trajectory of the hand (especially the fingertips) when holding the hand. Through the continuous change of the tangential direction of the arc, it covers the multi-directional sliding that the hand may produce during the holding process (including tangential sliding caused by lateral, diagonal and torsional directions); when the hand makes a slight displacement, the arc-shaped texture can always provide friction perpendicular to the instantaneous sliding direction, avoiding the insufficient protection of non-primary sliding by the straight texture when the direction is fixed.

[0027] A further technical solution is that the end of the protective sleeve away from the water jet pipe is connected to a sealing strip, and the sealing strip is provided with a clearance hole corresponding to the spray gun; An adhesive element is attached to the sealing strip, which can seal the inner cavity of the protective sleeve by adhering to the outer surface of the protective sleeve.

[0028] The protective sleeve has an inner cavity with an opening through which the spray gun enters the inner cavity. This is the existing design and will not be described in detail here.

[0029] During sealing, the sealing strip bends and passes through the clearance hole to avoid the spray gun (which can be the feed end of the spray gun), so that the adhesive part adheres to the outer surface of the protective sleeve, thereby sealing the inner cavity of the protective sleeve. It can also restrict the part of the spray gun inserted into the inner cavity to be within the inner cavity, reducing the risk of relative sliding between the protective sleeve and the spray gun, avoiding unstable grip due to the displacement of the protective sleeve relative to the spray gun, and further reducing the risk of the spray gun slipping.

[0030] In some embodiments, the adhesive component is provided as a double-sided adhesive layer, and the double-sided adhesive layer is provided on both sides of the clearance hole (see...). Figure 1 ).

[0031] In a further technical solution, the protective sleeve is provided with at least one pressure-applying component, which can make the protective sleeve fit tightly against the spray gun.

[0032] The pressure-applying component is preferably a single unit and can be an elastic structure, such as a rubber band. There are no restrictions on the width or other dimensions of the pressure-applying component.

[0033] To help understand, let's take a rubber band as an example of the pressure-applying component. The rubber band itself has a certain elasticity and surface roughness. After the rubber band is put on the outside of the protective sleeve, when a person holds it, the rubber band can directly contact the palm. This can increase the friction between the hand and the protective sleeve. This effect is more obvious when the outer surface of the protective sleeve is relatively smooth, reducing the possibility of the hand slipping when holding the spray gun and further reducing the risk of the spray gun slipping.

[0034] To further illustrate this point, let's use a rubber band as an example of the pressure-applying component. The elasticity of the rubber band creates an inward restraining force on the protective sleeve, allowing it to fit more tightly against the outside of the spray gun. This reduces the risk of the protective sleeve slipping relative to the spray gun, preventing instability in the grip due to the protective sleeve shifting relative to the spray gun, and thus further reducing the risk of the spray gun slipping.

[0035] A further technical solution involves a single pressure-applying component, which is fitted onto the outside of the anti-slip area to fit the operator's grip, ensuring both grip effectiveness and comfort while reducing the risk of the spray gun slipping. Multiple pressure-applying components can also be used.

[0036] Preferably, a single pressure-applying element is fitted onto the outer side of the middle of the anti-slip area.

[0037] A further technical solution involves using either a strap or adhesive tape as the pressure-applying component. Using a strap or adhesive tape as the pressure-applying component can achieve the same effect as a rubber band, and provides greater stability in achieving this effect over a long period. The adhesive tape can be double-sided. The use of straps and adhesive tape is well-known and will not be elaborated upon here.

[0043] The working principle and advantages of this utility model are as follows: The operator typically holds the spray gun in the middle area. The anti-slip area on the outer surface of the protective sleeve is aligned with this middle area. The anti-slip area has anti-slip textures, which can contact the operator's hand or the glove worn on the outside of the hand (hereinafter referred to as the hand). This increases the friction between the protective sleeve and the operator's hand, reduces the risk of the spray gun slipping due to the protective sleeve shifting relative to the operator's hand, avoids affecting the operator's stable use of the spray gun, and reduces the risk of accidents caused by the spray gun slipping.

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0047] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0048] See Figures 1-2 A three-in-one spray gun anti-slip protection structure, comprising a spray gun 1, a water jet pipe 2, and a protective sleeve 3; The discharge end of the spray gun 1 is connected to the water-air pipe 2. The protective sleeve 3 is fitted onto the outside of the spray gun 1 and is tightly fitted to the water jet pipe 2; The outer surface of the protective sleeve 3 is provided with an anti-slip area, and the anti-slip area is provided with anti-slip texture 4; The anti-slip area is aligned with the middle area of ​​the spray gun 1 along its own length.

[0049] The spray gun 1, water jet pipe 2, and protective sleeve 3 are existing components, and their specific arrangement can refer to the existing configuration. Preferably, the protective sleeve 3 can adopt a contour-following design to correspond to the spray gun 1 and water jet pipe 2, achieving a tight fit with them.

[0050] Operators (such as doctors) typically hold the spray gun 1 in the middle area. The anti-slip area on the outer surface of the protective sleeve 3 is aligned with this middle area. The anti-slip area has anti-slip textures 4, which can contact the operator's hand or the glove worn on the outside of the hand (described below in terms of the hand). This increases the friction between the protective sleeve 3 and the operator's hand, reduces the risk of the spray gun 1 slipping due to the displacement of the protective sleeve 3 relative to the operator's hand, avoids affecting the operator's stable use of the spray gun 1, and reduces the risk of accidents caused by the spray gun 1 slipping.

[0051] Taking the middle area as an example, this area has no fixed range; it can be a 7-centimeter-long area or an 8-centimeter-long area. The middle area is only compared with the end area of ​​the spray gun 1 (such as the discharge end).

[0052] It should be noted that the water-air pipe 2 can also be called a water-air pipe or nozzle, which is an existing structure in the current three-way spray gun, used to transport water, air and mix them for spraying.

[0053] See Figure 1 In this embodiment, the anti-slip texture 4 is provided as multiple; In the unfolded state of the protective sleeve 3, each of the anti-slip textures 4 is arranged at intervals in the circumferential direction of the protective sleeve 3.

[0054] "Multiple" means at least two.

[0055] The anti-slip patterns 4 can be evenly spaced, and the spacing is not limited. The distribution range of the anti-slip patterns 4 in the circumferential direction of the protective cover 3 is not limited.

[0056] The unfolded state of the protective cover 3 refers to the state in which the protective cover 3 is not retracted to fit tightly against the spray gun 1.

[0057] In this section, the anti-slip textures 4 on the circumferential direction of the protective cover 3 can achieve uniform coverage of the friction force in the hand grip area, promoting a balanced anti-slip effect in each area of ​​the contact surface between the operator's hand and the anti-slip area.

[0058] See Figure 2 In this embodiment, the anti-slip texture 4 is provided as multiple; In the unfolded state of the protective sleeve 3, each of the anti-slip textures 4 is spaced apart along the length of the protective sleeve 3; With the protective sleeve 3 in a tight fit, each of the anti-slip textures 4 surrounds the spray gun 1.

[0059] Each anti-slip pattern 4 can be evenly spaced.

[0060] The tight fit of the protective cover 3 refers to the state in which the protective cover 3 is folded up and tightly fitted with the spray gun 1.

[0061] With the protective cover 3 unfolded, depending on the specific configuration, each anti-slip texture 4 can be considered as a circular texture (preferably) or an arc-shaped texture. For example, without considering the multi-segment configuration of the anti-slip texture 4, the anti-slip texture 4 can be circular or arc-shaped.

[0062] In this section, the texture direction can be considered as the extension direction perpendicular to the protective cover 3. The texture direction matches the radial gripping force direction of the hand, which can effectively improve the friction when pinching and gripping, and the anti-slip effect is outstanding when the main operation scenario is fixed grip.

[0063] In some embodiments, when the protective sleeve 3 is unfolded, a portion of the anti-slip textures 4 are spaced apart in the circumferential direction of the protective sleeve 3, and another portion of the anti-slip textures 4 are spaced apart in the longitudinal direction of the protective sleeve 3.

[0064] See Figures 1-2 In this embodiment, the anti-slip texture 4 includes a plurality of sequentially connected anti-slip segments 41, and at least some of the anti-slip segments 41 belonging to the same anti-slip texture 4 are arranged in opposite directions.

[0065] The anti-slip texture 4 may include three anti-slip sections 41, wherein the two anti-slip sections 41 at both ends extend in the same direction and are set in a different direction from the anti-slip section 41 in the middle.

[0066] Here, we take anti-slip texture 4, which includes a single vertical segment and a single inclined segment, as an example to help with understanding: When the vertical texture (vertical segment) and the inclined texture (inclined segment) are designed to be connected, the two textures can complement each other in direction, covering the main horizontal and diagonal force directions during gripping. Among them, the vertical texture mainly resists horizontal sliding, while the inclined texture specifically addresses diagonal sliding and torsional forces. The two form a continuous friction interface through connection, ensuring that when the hand undergoes slight displacement or changes in force direction, there is always a corresponding texture to provide stable friction, avoiding the failure of anti-slip in a single-direction texture in non-main force directions, thereby improving the overall reliability and comprehensiveness of anti-slip.

[0067] See Figures 1-2 In this embodiment, each of the anti-slip sections 41 is arc-shaped.

[0068] Here, we take the anti-slip texture 4, which includes two arc segments, as an example to help us understand: With the design of the two arc segments (anti-slip segment 41), the arc direction can be set according to the natural curling trajectory of the hand (especially the fingertips) when holding the hand. Through the continuous change of the tangential direction of the arc, it covers the multi-directional sliding that the hand may produce during the holding process (including tangential sliding caused by lateral, diagonal and torsional movements). When the hand makes a slight displacement, the arc texture can always provide friction perpendicular to the instantaneous sliding direction, avoiding the insufficient protection of non-primary sliding by the straight texture when the direction is fixed.

[0069] See Figures 1-2 In this embodiment, the end of the protective sleeve 3 away from the water pipe 2 is connected to a sealing strip 5, and the sealing strip 5 is provided with an avoidance hole 51 corresponding to the spray gun 1; An adhesive element 6 is attached to the sealing strip 5, which can seal the inner cavity of the protective sleeve 3 by adhering to the outer surface of the protective sleeve 3.

[0070] The protective sleeve 3 has an inner cavity with an opening through which the spray gun 1 enters the inner cavity. This is the existing type and will not be described in detail here.

[0071] When sealing, the sealing strip 5 bends and passes through the clearance hole 51 to avoid the spray gun 1 (which can be the feed end of the spray gun 1), so that the adhesive part 6 adheres to the outer surface of the protective sleeve 3, thereby sealing the inner cavity of the protective sleeve 3. It can also restrict the part of the spray gun 1 inserted into the inner cavity to the inner cavity, reducing the risk of relative sliding between the protective sleeve 3 and the spray gun 1, avoiding unstable grip caused by the displacement of the protective sleeve 3 relative to the spray gun 1, and further reducing the risk of the spray gun 1 slipping.

[0072] In some embodiments, the adhesive element 6 is provided as a double-sided adhesive layer, and the double-sided adhesive layer is provided on both sides of the clearance hole 51 (see...). Figure 1 ).

[0073] In this embodiment, the protective sleeve 3 is provided with at least one pressure-applying member 7, which can make the protective sleeve 3 fit tightly against the spray gun 1.

[0074] The pressure-applying component 7 can be fitted onto the outside of the protective sleeve 3, and continuously apply pressure to the protective sleeve 3 to make the protective sleeve 3 (which may be a part, such as the anti-slip area) fit tightly against the spray gun 1.

[0075] The pressure-applying component 7 is preferably a single unit and can be an elastic structure, such as a rubber band. The width and other dimensions of the pressure-applying component 7 are not limited.

[0076] To illustrate this point, let's take the pressure-applying component 7 as an example of a rubber band. The rubber band itself has a certain elasticity and surface roughness. After the rubber band is put on the outside of the protective sleeve 3, when a person holds it, the rubber band can directly contact the palm. This can increase the friction between the hand and the protective sleeve 3. This effect is more obvious when the outer surface of the protective sleeve 3 is relatively smooth, reducing the possibility of the hand slipping when holding the spray gun 1 and further reducing the risk of the spray gun 1 slipping.

[0077] To further illustrate this point, let's take the pressure-applying component 7 as an example of a rubber band. The elasticity of the rubber band will exert an inward restraining force on the protective sleeve 3, allowing the protective sleeve 3 to fit more tightly against the outside of the spray gun 1. This reduces the risk of relative slippage between the protective sleeve 3 and the spray gun 1, and avoids unstable grip caused by the displacement of the protective sleeve 3 relative to the spray gun 1, thereby further reducing the risk of the spray gun 1 slipping.

[0078] In this embodiment, the pressure-applying component 7 is a single component, and it is fitted onto the outside of the anti-slip area to fit the operator's grip, ensuring the operator's grip effectiveness and comfort while reducing the risk of the spray gun 1 slipping. Multiple pressure-applying components 7 may also be used.

[0079] Preferably, seven individual pressure-applying components are set on the outer side of the middle of the anti-slip area.

[0080] In this embodiment, the pressure-applying component 7 is either a strap or adhesive tape. Using a strap or adhesive tape as the pressure-applying component 7 can achieve the same effect as the rubber band described above, and provides higher stability in achieving this effect over a long period. The adhesive tape can be double-sided tape. The use of straps and adhesive tape is well-known and will not be elaborated upon here.

[0081] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
