However, the drawings in the following description are only some of the embodiments of the present invention, and those skilled in the art can derive other drawings based on these drawings without any creative work.

[0019] In order to make the objectives, technical means and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical means in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention, but it is clear that the described embodiments are not all embodiments but only some embodiments of the present invention.
[0020] As shown in Figures 1 to 7, the foam generator of this embodiment is a device that generates foam, and can be used as a hand soap device, a foam pack device, or any other device that generates foam.
[0021] Specifically, the foam generator includes a main body 100, a liquid supply component 200, a first liquid flow path 300, a second liquid flow path 400, and a foaming unit 500. The main body 100 functions as a base carrier for the foam generator, supporting the other components. The main body 100 is provided with a transition cavity 110 and an inlet 120 and an outlet 130 communicating with the transition cavity. The foaming unit 500 is detachably mounted within the transition cavity 110. In this manner, if the foaming unit 500 becomes clogged, the user can remove the foaming unit 500 from the transition cavity 110 for maintenance. This facilitates maintenance of the foaming unit 500 of the hand soap device without the need for complete replacement, thereby reducing user maintenance costs. For example, the transition cavity 110 may be surrounded by the main body 100 itself or by other components connected to the main body 100, but this is not a limitation.
[0022] The discharge port of the liquid supply component 200 is connected to one end of the first liquid flow path 300, the other end of the first liquid flow path 300 is connected to the inlet 120, and the outlet 130 is connected to one end of the second liquid flow path 400. The gas and liquid supplied from the liquid supply component 200 passes through the first liquid flow path 300, the inlet 120, and the foaming unit 500 in this order to generate foam, which then flows out through the outlet 130 and the second liquid flow path 400 for use by a user. For example, the first liquid flow path 300 and the second liquid flow path 400 may be flow paths formed within the main body 100, and the first liquid flow path 300 may be a pipe, such as a PVC tube or a metal tube.
[0023] The specific structure of liquid supply component 200 can refer to conventional technology, and can employ a principle in which an internal pumping device such as a diaphragm pump or gear pump is driven by a motor to extract liquid, and the pump creates negative pressure at the intake port, drawing in air and mixing the liquid with the air at a certain ratio; in this case, liquid supply component 200 also has an intake port. Alternatively, a centrifugal rotor can be rotated by a motor to send the hand soap flying to the edge and mix it with the air; however, this is not particularly limited here.
[0024] Here, the transition cavity 110 further includes an attachment port 140 , and the foaming unit 500 is detachably attached to the transition cavity 110 through the attachment port 140 , and can be easily removed from the attachment port 140 .
[0025] In some embodiments, when the foam unit 500 is installed in the transition cavity 110 , the foam unit 500 can seal the access port 140 to prevent leakage of liquid within the transition cavity 110 .
[0026] In another embodiment, as shown in Figures 3 to 6, the foam generator further includes a seal cap 600 to prevent the liquid in the transition cavity 110 from leaking, and the seal cap 600 is removably attached to the mounting port 140 and seals the mounting port 140 with the seal cap 600.
[0027] Furthermore, a sealing component can be provided between the seal cap 600 and the mounting opening 140, thereby enhancing the sealing effect.
[0028] 3 to 5 , the transition cavity 110 includes a first cavity 111 and a second cavity 112 that are connected to each other, the inlet 120 is connected to the outlet 130 via the first cavity 111 and the second cavity 112 in that order, the foaming unit 500 is at least partially located within the second cavity 112, and the attachment port 140 is connected directly to the first cavity 111. In this manner, the liquid supplied from the liquid supply component 200 flows through the inlet 120 into the first cavity 111, then passes through the foaming unit 500 to generate foam, and is then discharged through the outlet 130.
[0029] To facilitate removal of the foaming unit 500 from the second cavity 112, in some embodiments, the second cavity 112 is provided with a gripping groove 113 at an end adjacent to the first cavity 111, and the foaming unit 500 is provided with an outer flange 510 at one end adjacent to the second cavity 112, the outer flange 510 extending at least partially to the gripping groove 113 and having a predetermined distance from the bottom of the gripping groove 113. This allows a gripping tool or fingers to be placed between the outer flange 510 and the bottom of the gripping groove 113, thereby facilitating removal of the foaming unit 500 from the second cavity 112 via the outer flange 510.
[0030] Furthermore, a sealing element is provided between the foaming unit 500 and the inner wall surface of the second cavity 112, which prevents gas and liquid from flowing between the foaming unit 500 and the inner wall surface of the second cavity 112, and allows the gas and liquid to pass through the foaming unit 500, thereby improving the foam forming effect.
[0031] In some embodiments, the main body 100 includes an upper body 101 and a lower body 102 that are detachably connected, and the liquid supply component 200, the first liquid flow path 300, the second liquid flow path 400, and the foaming unit 500 are provided 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 blocks the mounting port 140, preventing the area where the foaming unit 500 is attached from being exposed and improving the appearance.
[0032] Among these, the liquid supply component 200 can extract liquid from the external environment.
[0033] Of course, the liquid supply component 200 may extract the liquid inside the main body 100. For example, the main body 100 may have a solution cavity for storing the solution (hand soap) inside the solution cavity, and more specifically, the solution cavity may be provided in the lower main body 102, and the outlet of the liquid supply component 200 may be connected to the solution cavity, allowing the liquid inside the solution cavity to be extracted.
[0034] In some embodiments, the foaming unit 500 includes a first foaming net 520, a second foaming net 530, and a support ring 540, with the first foaming net 520 and the second foaming net 530 positioned on opposite ends of the support ring 540. The outer flange 510 is attached to the support ring 540.
[0035] Furthermore, since the first foam net 520 and the second foam net 530 are detachably connected to the support ring 540, if the first foam net 520 and the second foam net 530 become clogged or damaged, the first foam net 520 and the second foam net 530 can be cleaned or replaced separately. Illustratively, the first foam net 520 and the second foam net 530 may be abutted against both ends of the support ring 540, or the first foam net 520 and the second foam net 530 may be fitted and arranged at both ends of the support ring 540.
[0036] Based on the same inventive idea, the present invention also provides a hand soap device including the foam generator.
