[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.
[0032] like Figures 1 to 7 As shown, the foam machine of this embodiment is a device that generates foam. It can be used as a hand sanitizer device, a foam mask device, or other devices that require foam generation.
[0033] Specifically, the foaming machine may include a body 100, a liquid dispensing component 200, a first liquid outlet channel 300, a second liquid outlet channel 400, and a foaming component 500. The body 100 serves as the basic carrier of the foaming machine, supporting other components. The body 100 has a transition cavity 110, and an inlet 120 and an outlet 130 communicating with the transition cavity 110. The foaming component 500 is detachably disposed within the transition cavity 110. Thus, when the foaming component 500 becomes clogged, the user can remove it from the transition cavity 110 for maintenance, facilitating repair without requiring complete replacement and reducing maintenance costs. For example, the transition cavity 110 may be formed by the body of the body 100 or by other components connected to the body 100; no specific limitation is made in this regard.
[0034] The outlet of the liquid supply component 200 is connected to one end of the first liquid outlet channel 300, the other end of the first liquid outlet channel 300 is connected to the inlet 120, and the outlet 130 is connected to one end of the second liquid outlet channel 400. This allows the gas-liquid mixture supplied by the liquid supply component 200 to sequentially pass through the first liquid outlet channel 300, the inlet 120, and the foaming component 500 to form foam, which then flows out through the outlet 130 and the second liquid outlet channel 400 for user use. For example, the first liquid outlet channel 300 and the second liquid outlet channel 400 can be channels formed within the machine body 100, and the liquid outlet pipe 300 can also be a pipe, such as a PVC pipe or a metal pipe.
[0035] It should be noted that the specific structure of the liquid dispensing component 200 can refer to existing technologies. The principle employed can be that a motor drives an internal diaphragm pump or gear pump to draw in liquid. Simultaneously, the pump creates negative pressure at the air inlet, drawing in air and mixing the liquid and air in a certain proportion. In this case, the liquid dispensing component 200 also has an air inlet. Alternatively, the principle can be that a motor drives a centrifugal rotor to rotate, causing the hand sanitizer to be thrown to the edge and mixed with air; no specific limitation is made here.
[0036] The transition cavity 110 also has an installation port 140, through which the foaming component 500 is detachably installed in the transition cavity 110, thus making it easy to remove from the installation port 140.
[0037] In some embodiments, when the foaming assembly 500 is installed in the transition cavity 110, the foaming assembly 500 can seal the installation port 140 to prevent liquid leakage from the transition cavity 110.
[0038] In some other embodiments, such as Figures 3 to 6As shown, the foam machine also includes a sealing cover 600, which is detachably installed on the mounting port 140, thereby sealing the mounting port 140 and preventing liquid leakage from the transition chamber 110.
[0039] Furthermore, a sealing element may be provided between the sealing cover 600 and the mounting port 140 to improve the sealing effect.
[0040] In some embodiments, such as Figures 3 to 5 As shown, the transition cavity 110 includes a first cavity 111 and a second cavity 112 that are interconnected. The inlet 120 is connected to the outlet 130 through the first cavity 111 and the second cavity 112 in sequence. The foaming component 500 is at least partially located in the second cavity 112, and the mounting port 140 is directly connected to the first cavity 111. In this way, the gas-liquid mixture supplied by the liquid supply component 200 enters the first cavity 111 through the inlet 120, then passes through the foaming component 500 to form foam, and then is discharged through the outlet 130.
[0041] To facilitate the removal of the foaming component 500 from the second cavity 112, in some embodiments, the second cavity 112 has a gripping groove 113 at one end adjacent to the first cavity 111, and the foaming component 500 has an outer flange 510 at one end adjacent to the second cavity 112. The outer flange 510 extends at least partially into the gripping groove 113 and is at a predetermined distance from the bottom of the gripping groove 113. This allows for the placement of gripping tools or fingers at the predetermined distance between the outer flange 510 and the bottom of the gripping groove 113, facilitating the removal of the foaming component 500 from the second cavity 112 via the outer flange 510.
[0042] Furthermore, a sealing element is provided between the foaming component 500 and the inner wall surface of the second cavity 112. This prevents gas and liquid from flowing away between the foaming component 500 and the inner wall surface of the second cavity 112, ensuring that both gas and liquid pass through the foaming component 500 and improving the foam forming effect.
[0043] In some embodiments, the body 100 includes an upper body 101 and a lower body 102 that are detachably connected. The liquid supply component 200, the first liquid outlet channel 300, the second liquid outlet channel 400, and the foaming component 500 are disposed on the upper body 101, and the mounting port 140 is located on the bottom surface of the upper body 101. When the upper body 101 and the lower body 102 are connected, the lower body 102 covers the mounting port 140, thereby preventing the area where the foaming component 500 is installed from being exposed and improving the aesthetics.
[0044] The liquid supply component 200 can draw liquid from the external environment.
[0045] Of course, the liquid dispensing component 200 can also draw liquid from inside the body 100. For example, the body 100 has a solution chamber for holding a solution (hand sanitizer). Specifically, the solution chamber can be located on the lower body 102, and the outlet of the liquid dispensing component 200 is connected to the solution chamber to draw liquid from the solution chamber.
[0046] In some embodiments, the foaming assembly 500 may include a first foaming net 520, a second foaming net 530, and a support ring 540, wherein the first foaming net 520 and the second foaming net 530 are located at both ends of the support ring 540. The aforementioned outer flange 510 is provided on the support ring 540.
[0047] Furthermore, the first foaming net 520 and the second foaming net 530 are detachably connected to the support ring 540, so that when the first foaming net 520 and the second foaming net 530 become clogged or damaged, they can be cleaned or replaced individually. For example, the first foaming net 520 and the second foaming net 530 can abut against both ends of the support ring 540, or they can be interference-fitted at both ends of the support ring 540.
[0048] Based on the same inventive concept, this disclosure also provides a hand sanitizer device, which includes the aforementioned foaming machine.
[0049] It should be noted that the specific structure of the foam machine can be found in the detailed description in the above embodiments, and will not be repeated here.
