Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a device for adjusting the uniformity of the spray surface of a foam pot. Background Technology

[0002] A foam sprayer is a device that uses high-pressure water to mix and dilute chemical cleaning solutions and then spray out foam.

[0003] Most spray bottles on the market today adjust the spray angle by opening and closing a U-shaped metal strip. It's clear that the manufacturing process for this metal U-shaped strip requires very high precision. Burrs on the U-shaped strip can significantly affect the spray pattern. Furthermore, the U-shaped strip is prone to being clamped too tightly, resulting in uneven foam distribution, which affects the cleaning effect and causes persistent dripping at the nozzle. Therefore, its stability is relatively poor. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing another highly stable and compact foam spray uniformity adjustment device.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0006] A device for adjusting the uniformity of a foam spray surface is disclosed. The foam spray surface includes a hollow body and a cylindrical body. The inner end of the body is connected to and communicates with the body. The outer end of the body has an outlet communicating with its inner cavity. The device is characterized in that the uniformity adjustment device is located at the outlet and includes a water-shaped core, an adjusting cap, and a rotating wheel. The water-shaped core is long and rod-shaped with a limiting part in the middle and a water-blocking part at its outer end. The inner end of the water-shaped core is fixed to the body. The adjusting cap is cylindrical and its inner end is fitted onto the body. The adjusting cap can move along the axis of the body under external force. The outer end of the adjusting cap has a through-hole. Initially, the water-blocking part is away from the water-blocking hole. After applying external force to move the adjusting cap axially relative to the body, the water-blocking part can be located at the water-blocking hole.

[0007] In the above-mentioned foam spray uniformity adjustment device, the adjustment cap is threadedly connected to the main body.

[0008] In the above-mentioned foam spray uniformity adjustment device, the side of the adjustment cap has a spirally recessed groove, and a limiting pin is fixedly connected to the main body, the limiting pin being embedded in the groove.

[0009] In the above-mentioned foam spray uniformity adjustment device, the rotating wheel includes blades and an inner wheel and an outer wheel in an annular shape. The inner diameter of the outer wheel is larger than the outer diameter of the inner wheel. The blades are circumferentially distributed between the inner wheel and the outer wheel. The inner wheel and the outer wheel are fixedly connected by several blades.

[0010] In the above-mentioned foam spray uniformity adjustment device, the main body has a cylindrical connecting cylinder, and the water-shaped core is embedded in the connecting cylinder and the two are fixedly connected.

[0011] In the above-mentioned foam spray uniformity adjustment device, the inner wheel is sleeved on the water-shaped core and the inner wheel is limited between the limiting part and the connecting cylinder.

[0012] In the above-mentioned foam spray uniformity adjustment device, the blades and the inner wheel are arranged at an inclination in the radial direction.

[0013] In the above-mentioned foam spray uniformity adjustment device, the line connecting the upper and lower ends of the blade is inclined to the axis of the inner wheel.

[0014] In the above-mentioned foam spray uniformity adjustment device, the water-shaped core, the limiting part, and the water-blocking part are an integrated structure.

[0015] In the above-mentioned foam spray uniformity adjustment device, the outer side of the main body has an annular recessed sealing groove, and the sealing groove contains a sealing ring, which is pressed tightly between the adjustment cap and the main body.

[0016] In the above-mentioned foam spray uniformity adjustment device, the adjusting cap has a cylindrical water outlet tube located at the outer end of the adjusting cap. The spray hole includes a water outlet section one, a water outlet section two, and a water outlet section three. The water outlet section two is a straight hole, while the water outlet section one and the water outlet section three are both conical holes. The small-sized ends of the water outlet section one and the water outlet section three are respectively connected to the two ends of the water outlet section two. The large-sized end of the water outlet section one is located inside the adjusting cap, and the large-sized end of the water outlet section three is located outside the water outlet tube.

[0017] In the above-mentioned foam spray uniformity adjustment device, the large-size end dimension of the third water outlet section is A, and the large-size end dimension of the first water outlet section is B, where A is greater than B.

[0018] Compared to existing technologies, the uniformity adjustment device for the spray surface of this foam pot allows the water-blocking part of the water-generating core to be positioned at different locations in the spray hole by changing the position of the adjusting cap according to actual conditions, thereby outputting water mist with different pressures and diffusion areas. In actual operation, the device can be selected according to the actual situation, making it highly adaptable.

[0019] Meanwhile, the water-shaped core and rotating wheel are all located inside the adjusting cap, so the entire device has a relatively compact structure and high practical value. Attached Figure Description

[0031] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-6As shown, the foam pot includes a hollow pot body and a cylindrical body 1. The inner end of the body 1 is connected to and communicates with the pot body, and the outer end of the body 1 has an outlet that communicates with its inner cavity.

[0034] The kettle body also has a pressure-pressurizing structure. Since the pressure-pressurizing structure is existing technology and the technical innovation of this patent application is unrelated to the pressure-pressurizing structure, the technical features of the pressure-pressurizing structure will not be described in detail in the embodiments.

[0035] Under the action of the pressurization structure, the cleaning liquid in the pot can be smoothly output from the main body 1.

[0036] The uniformity adjustment device for the spray surface of this foam bottle is located at the outlet and includes a water-shaped core 2, an adjustment cap 4, and a rotating wheel 3. The water-shaped core 2 is long and rod-shaped, with a limiting part 2a in the middle and a water-blocking part 2b at the outer end 2b.

[0037] In this embodiment, the limiting part 2a protrudes circumferentially from the outside of the water-shaped core 1. The water-blocking part 2b also protrudes circumferentially from the outside of the water-shaped core 1.

[0038] The inner end of the water-shaped core 1 is fixed to the body 1. The adjusting cap 4 is cylindrical and its inner end is fitted onto the body 1 and the two are threaded together. The outer end of the adjusting cap 4 has a through water spray hole 4a. In the initial state, the water blocking part 2b is far away from the water spray hole. After applying an external force to make the adjusting cap 4 move axially relative to the body 1, the water blocking part 2b can be located at the water spray hole 4a.

[0039] This structure enables the adjusting cap to move along the axis of the main body under the action of external force.

[0040] During the process of the cleaning fluid in the main body 1 entering the water spray hole 4a, the cleaning fluid will pass through the rotating wheel 3 and the water-shaped core 2.

[0041] The rotating wheel 3 is axially fixed to the water-shaped core 2, but the water-shaped core 2 can rotate relative to it. Therefore, under the continuous pressure of the cleaning fluid, the rotating wheel 3 can rotate stably and continuously. At the same time, the adjusting cap 4 can move axially relative to the body 1. Therefore, after the adjusting cap 4 moves, it can change the size of the gap between the water-blocking part 2b and the spray hole 4a.

[0042] It can be seen that the continuously rotating wheel 3 causes the cleaning fluid to enter the spray hole 4a in a rotating state. After the adjusting cap 4 is activated, it can correspondingly change the gap between the water-blocking part 2b and the spray hole 4a. Thus, it ultimately controls the diffusion area and water output when the cleaning fluid is output. Its spray shape is similar to a truncated cone structure, that is, it is sprayed out in the form of a water outlet surface. Specifically, its sprayed water outlet has a conical cylindrical structure.

[0043] The rotating wheel 3 includes blades 3c and annular inner wheel 3a and outer wheel 3b. The inner diameter of the outer wheel 3b is larger than the outer diameter of the inner wheel 3a. The blades 3c are evenly distributed circumferentially between the inner wheel 3a and the outer wheel 3b. The inner wheel 3a and the outer wheel 3b are fixedly connected by a number of blades 3c.

[0044] Several blades 3c can be stably connected to the inner wheel 3a and the outer wheel 3b.

[0045] The main body 1 has a cylindrical connecting tube 1a, and the water-shaped core 2 is embedded in the connecting tube 1a and the two are fixedly connected.

[0046] The connecting cylinder 1a on the main body 1 provides sufficient space for the water-shaped core 2 to be connected. Of course, the connecting cylinder 1a is not a solid cylindrical structure, and there are through water passage gaps at the sides and ends of the connecting cylinder 1a.

[0047] The inner wheel 3a is fitted onto the water-shaped core 2 and is limited between the limiting part 2a and the connecting cylinder 1a.

[0048] The inner wheel 3a is stably positioned between the limiting part 2a and the connecting cylinder 1a, ultimately fixing the rotating wheel 3 axially to the body 1. Of course, the circumferential direction of the rotating wheel 3 is not restricted, so the rotating wheel 3 will continue to rotate under the action of the cleaning fluid.

[0049] The blade 3c is inclined in the radial direction to the inner wheel 3a.

[0050] The line connecting the upper and lower ends of the blade 3c is inclined to the axis of the inner wheel 3a.

[0051] When the cleaning fluid acts on the inclined blade 3c, it enables the rotating wheel 3 to rotate more stably.

[0052] The water-shaped core 2, the limiting part 2a, and the water-blocking part 2b are an integral structure.

[0053] The outer side of the body 1 has an annular recessed sealing groove 1b, and the sealing groove 1b contains a sealing ring 5, which is pressed tightly between the adjusting cap 4 and the body 1.

[0054] The sealing groove 1b is used to position the sealing ring 5, and the sealing ring 5 can maintain a good seal between the adjusting cap 4 and the body 1.

[0055] The regulating cap 4 has a cylindrical water outlet tube 4b, which is located at the outer end of the regulating cap 4.

[0056] In this embodiment, the adjusting cap 4 and the water outlet cylinder 4b are an integral structure and are arranged on the same axis.

[0057] The spray hole 4a includes a first water outlet section 4c, a second water outlet section 4d, and a third water outlet section 4e. The second water outlet section 4d is a straight hole, while the first water outlet section 4c and the third water outlet section 4e are both conical holes. The small-sized ends of the first water outlet section 4c and the third water outlet section 4e are respectively connected to the two ends of the second water outlet section 4d. The large-sized end of the first water outlet section 4c is located inside the adjusting cap 4, and the large-sized end of the third water outlet section 4e is located outside the water outlet cylinder 4b.

[0058] Initially, the water-blocking part 2b is located at the outlet section 4e. At this time, the water output is large, but the spraying area is uneven.

[0059] When the water-blocking part 2b is located in the water outlet section 4d, the water flow rate decreases and the water pressure increases, thus enabling the spraying and diffusion of water mist over a large area.

[0060] Of course, in actual operation, the appropriate choice should be made between the two situations mentioned above based on the actual circumstances.

[0061] The larger end dimension of the water outlet section 3 4e is A, and the larger end dimension of the water outlet section 1 4c is B, wherein A is greater than B.

[0062] It can be seen that the above structure allows for a relatively low output pressure but a large volume of water mist in the initial state. After adjusting the cap, the output pressure becomes relatively high, but the volume of water mist becomes small.

[0063] The uniformity adjustment device of this foam sprayer allows the water-retaining core to be positioned at different locations within the spray nozzle by changing the position of the adjusting cap, thus outputting water mist with varying pressures and diffusion areas. In actual operation, the device can be selected according to specific conditions, making it highly adaptable.

[0064] Meanwhile, the water-shaped core and rotating wheel are all located inside the adjusting cap, so the entire device has a relatively compact structure and high practical value.

[0065] Example 2

[0066] The structure of the adjusting device in this embodiment is basically the same as that in the previous embodiment, except that:

[0067] The adjusting cap has a spirally recessed groove on its side, and a limiting pin is fixedly connected to the main body. The limiting pin is embedded in the groove. Figure 7 and Figure 8 and Figure 9 As shown.

[0068] This structure enables the adjusting cap to move along the axis of the main body under the action of external force.

[0069] Specifically, when an external force is applied to push the adjusting cap, the spiral groove and the limiting pin work together to cause the adjusting cap to move along the axis of its body. Of course, there is appropriate frictional resistance between the limiting pin and the groove, so the adjusting cap can only move when an external force is applied.

[0070] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0071] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
