Description

Technical Field

[0001] The invention relates to the technical field of cosmetic packaging materials, in particular to a sprayer which can be used for atomizing viscous materials. Background Art

[0002] With the development of society, the texture of the materials contained in spray packaging, which is widely used in daily life, is becoming more and more diverse. In order to achieve the best use effect, some more viscous materials are also beginning to need to be atomized. However, many sprayers at this stage do not have ideal spray effects on viscous materials.

[0003] Atomization is the process of breaking liquid into fine particles using a nozzle. Currently, a double spring structure is set in the spray pump core to enhance the instantaneous explosive force of the sprayer to extrude the material and improve the spray effect. Although this type of sprayer has a certain improvement in the spray effect of viscous materials, there are still frequent nozzle blockages or spray interruptions. In addition, the existing single-hole mode nozzle does not fully atomize the spray particles, and the spray effect needs to be improved. In addition, nozzle blockage will make it difficult for users to press and inconvenient to operate. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a sprayer which can be used for viscous materials, and the sprayer has the advantages of low spray hole blockage rate, large atomization coverage area, good spray effect, high spray efficiency, convenient and fast operation, etc.

[0005] In order to solve the above technical problems, the present invention adopts the following technical scheme: a sprayer that can be used for atomizing viscous materials, comprising a cap, a nozzle, a pump core assembly and a bottle, wherein a guide groove is arranged on the nozzle, and the guide groove is composed of a first arcuate wall, a second arcuate wall, a third arcuate wall, a fourth arcuate wall which are connected in sequence and have different radii, and a spray hole arranged in the guide groove; the first arcuate wall is a feeding section, the second arcuate wall and the fourth arcuate wall are guide sections, and the third arcuate wall is a discharging section.

[0006] Further, the radius of the first arc-shaped wall is smaller than the radius of the third arc-shaped wall.

[0007] Furthermore, the radius of the second arc-shaped wall is greater than the radius of the fourth arc-shaped wall.

[0008] Furthermore, the radius of the third arc-shaped wall is smaller than the radius of the fourth arc-shaped wall.

[0009] Furthermore, at least three guide grooves are arranged on the nozzle, and the guide grooves are distributed in a circular array around the center point of the nozzle, and the injection holes of the guide grooves are distributed in a circular array around the center point of the nozzle.

[0010] Furthermore, the injection hole can be arranged at the center position of the discharge section in the guide groove, or at the edge of the discharge section in the guide groove and close to the third arc-shaped wall, or close to the fourth arc-shaped wall, or close to the second arc-shaped wall, or at other positions in the guide groove.

[0011] Furthermore, the height of each arc-shaped wall in the guide groove ranges from 0.2 mm to 0.6 mm.

[0012] Furthermore, the diameter of the injection hole ranges from 0.15 mm to 0.3 mm.

[0013] Furthermore, a liquid outlet channel is provided in the press cap, a central column is provided in the liquid outlet channel, the central column is inserted into the inner cavity of the nozzle, and abuts against the guide groove at the guide section and the discharge section.

[0014] Furthermore, a snap ring is provided on the nozzle, and a snap groove for snapping with the snap ring is provided on the push cap.

[0015] Furthermore, the feed end of the injection hole is processed with a conical chamfer.

[0016] Furthermore, a conical groove is provided on the outer side of the nozzle, and the height of the conical groove is preferably 0.3 mm to 0.5 mm.

[0017] Furthermore, the nozzle is also provided with a sealing ring, which is sealed and matched with the liquid outlet channel of the push cap.

[0018] Furthermore, the diameter of the central column is 0.5 mm to 0.7 mm smaller than the diameter of the nozzle cavity, and the spray material enters the feed section of the guide groove through the gap between the central column and the nozzle cavity.

[0019] The sprayer provided by the present invention can be used for atomizing viscous materials, and has the following beneficial effects compared with the prior art: First, the sprayer is provided with a guide groove on the nozzle, and the guide groove is composed of a first arc-shaped wall, a second arc-shaped wall, a third arc-shaped wall, a fourth arc-shaped wall which are connected in sequence and have different radii, and a spray hole arranged in the guide groove; the first arc-shaped wall is a feeding section, the second arc-shaped wall and the fourth arc-shaped wall are guide sections, and the third arc-shaped wall is a discharge section. When the viscous material enters the feeding section of the guide groove, thanks to the arc-shaped structure of the guide groove, the viscous material forms a vortex after entering the guide groove, which increases the disturbance of the material particles, so that the material particles finally cut into the spray hole at a high speed in a turbulent state and spray out, thereby increasing the atomization coverage area and enhancing the spraying effect. Secondly, the sprayer is easy and fast to operate, which can bring a better replacement experience to the user. Finally, the sprayer has a plurality of evenly distributed guide grooves in the nozzle and a spray hole in each guide groove. The plurality of spray holes can spray the material body quickly, so that the viscous medium will not be retained, thereby reducing blockage and improving the spraying efficiency.

DETAILED DESCRIPTION

[0024] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", etc. should be understood in a broad sense. For example, it can be a fixed connection (such as clamping, threaded connection, riveting, welding), a detachable connection, or an integral connection; of course, it can also be a mechanical connection or an electrical connection; in addition, it can also be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] It should be noted that: in the embodiments of the present invention, the number of arc-shaped walls in the guide groove 101 can be 3, 4 or 5 or other numbers, and the present application does not make any special restrictions on this, and the following embodiments are only exemplary examples. In addition, the injection hole 102 can be arranged in the guide groove 101 near the third arc-shaped wall 1013, or in the guide groove 101 near the fourth arc-shaped wall 1014, or in the guide groove 101 near the second arc-shaped wall 1012, or in other positions in the guide groove 101, and the present application does not make any special restrictions on this, and the following embodiments are only exemplary examples. The following are 3 exemplary embodiments of the present application: Example 1

[0028] like Figures 1 to 10As shown, a sprayer that can be used for viscous materials, a sprayer that can be used for atomizing viscous materials, includes a nozzle 1, a press cap 2, a shoulder sleeve 3, a sealing gasket 4, a pump core assembly 5, and a bottle 6. Three guide grooves 101 are arranged on the nozzle 1, and the guide groove 101 is composed of a first arcuate wall 1011, a second arcuate wall 1012, a third arcuate wall 1013, a fourth arcuate wall 1014 that are connected in sequence and have different radii, and an injection hole 102 arranged in the guide groove 101 near the third arcuate wall 1013; the first arcuate wall 1011 is used as a feeding section 1015, the second arcuate wall 1012 and the fourth arcuate wall 1014 are used as guide sections 1016, and the third arcuate wall 1013 is used as a discharging section 1017. The injection hole 102 in this embodiment 1 is located at the center of the discharge section 1017, and the radii of the first arc wall 1011, the second arc wall 1012, the third arc wall 1013, and the fourth arc wall 1014 are different, so that the guide groove 101 presents a bent, lentil-shaped or other asymmetric shape.

[0029] It should be noted that the radii of the first curved wall 1011, the second curved wall 1012, the third curved wall 1013, and the fourth curved wall 1014 are different. Preferably, the radius of the first curved wall 1011 is smaller than the radius of the third curved wall 1013, and preferably slightly smaller; the radius of the second curved wall 1012 is larger than the radius of the fourth curved wall 1014, and the radius of the third curved wall 1013 is smaller than the radius of the fourth curved wall 1014.

[0030] The guide grooves 101 are distributed in a circular array around the center point of the nozzle 1, and the injection holes 102 of the guide grooves 101 are also distributed in a circular array around the center point of the nozzle 1. It is precisely because of the arc structure of the guide grooves 101 that the material body can form a vortex after entering the guide grooves 101. Since the guide grooves 101 are perpendicular to the liquid outlet channel 202, the material body particles have both axial velocity components and radial velocity components, which increases the disturbance of the ejected material body. Finally, the material body will cut into the injection hole 102 at a high speed in a turbulent state, which can effectively improve the spray effect.

[0031] Preferably, when the height range of each arcuate wall in the guide groove 101 is 0.2 mm to 0.6 mm, that is, the height range of the first arcuate wall 1011, the second arcuate wall 1012, the third arcuate wall 1013 and the fourth arcuate wall 1014 are all 0.2 mm to 0.3 mm, the beneficial effect of the scheme is best.

[0032] Preferably, when the diameter of the injection hole 102 is in the range of 0.15 mm to 0.3 mm, the beneficial effect of the solution is optimal.

[0033] Furthermore, a liquid outlet channel 202 is provided in the press cap 2, and a central column 2021 is provided in the liquid outlet channel 202. The central column 2021 is inserted into the inner cavity of the nozzle 1, and abuts against the guide section 1016 and the discharge section 1017 with the guide groove 101, that is, the guide section 1016 and the discharge section 1017 of the guide groove 101 are covered to prevent the material body from entering the guide groove 101 from the guide section 1016 and the discharge section 1017, thereby affecting the vortex effect of the material body in the guide groove 101.

[0034] Furthermore, a snap ring 104 is provided on the nozzle 1, and a slot 201 for snapping with the snap ring 104 is provided on the push cap 2. The nozzle 1 is also provided with a sealing ring 105 for cooperating with the liquid outlet channel 202 of the push cap 2 to achieve sealing of the material body.

[0035] Furthermore, the feed portion of the injection hole 102 is processed with a conical chamfer to facilitate rapid flow of the material.

[0036] Furthermore, a conical groove 103 is provided on the outer side of the nozzle 1 to increase the coverage of the spray, and the height of the conical groove 103 is 0.3 mm to 0.5 mm.

[0037] Furthermore, the diameter of the central column 2021 is 0.5 mm to 0.7 mm smaller than the inner diameter of the nozzle 1 , and the viscous material to be sprayed enters the feed section 1015 of the guide groove 101 through the gap between the central column 2021 and the inner cavity of the nozzle 1 .

[0038] Furthermore, the push cap 2 is snap-connected with the pump core assembly 5. Preferably, the pump core assembly 5 should use a high-explosive-force spray pump on the market to increase the explosive force of the material extrusion. At the same time, it is better to use it with the nozzle 1 provided in this embodiment. The pump core assembly 5 is installed on the shoulder sleeve 3 and is connected to the bottle 6 together with the sealing gasket 4 through threads or the like. Example 2

[0039] See also Figure 11~Figure 14As shown, three guide grooves 101 are arranged on the nozzle 1, and the guide groove 101 consists of a first arcuate wall 1011, a second arcuate wall 1012, a third arcuate wall 1013, a fourth arcuate wall 1014 which are connected in sequence and have different radii, and an injection hole 102 arranged in the guide groove 101 near the third arcuate wall 1013; the first arcuate wall 1011 serves as a feeding section 1015, the second arcuate wall 1012 and the fourth arcuate wall 1014 serve as a guide section 1016, and the third arcuate wall 1013 serves as a discharging section 1017. The injection hole 102 in this embodiment 2 is located at the edge of the discharge section 1017 and close to the third curved wall 1013. The radii of the first curved wall 1011, the second curved wall 1012, the third curved wall 1013, and the fourth curved wall 1014 are different, so that the guide groove 101 presents a bent, lentil-shaped or other asymmetric shape.

[0040] The parts not described or recorded in detail in this embodiment 2 are the same as those in embodiment 1 and will not be repeated here. Example 3

[0041] See also Figure 15~Figure 18 As shown, four guide grooves 101 are arranged on the nozzle 1, and the guide groove 101 is composed of a first arc wall 1011, a second arc wall 1012, a third arc wall 1013, a fourth arc wall 1014 which are connected in sequence and have different radii, and a spray hole 102 arranged in the guide groove 101 near the third arc wall 1013; the first arc wall 1011 is used as a feed section 1015, the second arc wall 1012 and the fourth arc wall 1014 are used as a guide section 1016, and the third arc wall 1013 is used as a discharge section 1017. In Example 3, the spray hole 102 is located at the center of the discharge section 1017, and the first arc wall 1011, the second arc wall 1012, the third arc wall 1013, and the fourth arc wall 1014 have different radii, so that the guide groove 101 presents a bent shape, a lentil shape, or other asymmetric shapes.

[0042] The parts not described or recorded in detail in this embodiment 3 are the same as those in embodiment 1 and will not be described in detail here.

[0043] like Figures 1 to 18As shown, when the user uses the sprayer, he presses the button cap 2, and the material is pressed into the liquid outlet channel 202 through the pump core assembly 5, and flows into the nozzle 1 under pressure. Since the nozzle 1 is provided with a plurality of evenly distributed guide grooves 101, when the material passes through the liquid outlet channel 202 and is squeezed into the feed section 1015 of the guide groove 101, thanks to the arc structure of the guide groove 101, the material forms a vortex after entering the guide groove 101. Since the guide groove 101 is perpendicular to the liquid outlet channel 202, the material particles have both an axial velocity component and a radial velocity component, which increases the disturbance of the ejected material, so that the material particles finally cut into the injection hole 102 at a high speed in a turbulent state and are ejected, thereby increasing the atomization coverage area and enhancing the injection effect.

[0044] In addition, the sprayer is easy and fast to operate, which can bring a better replacement experience to the user. Finally, the sprayer, by setting a plurality of evenly distributed guide grooves 101 in the nozzle 1, and setting a spray hole 102 in each guide groove 101, the plurality of spray holes 102 can quickly spray the material body, so that the viscous medium will not be retained, thereby reducing blockage and improving the spraying efficiency.
