Description

Technical Field

[0001] This application relates to the field of bathroom product technology, and in particular to a foaming bath machine. Background Technology

[0002] Existing foaming bath devices generally include foaming functions to enhance the bathing experience. However, these products have many shortcomings in terms of user experience, structural cost, and operational reliability. Specifically, most products have numerous function buttons, requiring users to control water circuit switching, foaming start / stop, etc., making the operation process complex and inconvenient. More importantly, the foaming process cannot be precisely controlled; the foaming time is neither visible nor adjustable, preventing users from taking the required amount of foam and easily leading to waste of foaming liquid and water / electricity resources. Utility Model Content

[0003] Therefore, it is necessary to provide a foaming bath machine to address the aforementioned problems.

[0004] This application provides a foaming bath machine, including a foaming device, an air pump device, a liquid pump device, a water circuit switching valve, a pressing device, and a reed switch;

[0005] The foaming device has a water inlet chamber, a foaming chamber, and a liquid guiding chamber. The first water inlet of the water inlet chamber is connected to an external water source. The first water outlet of the water inlet chamber is connected to the second water inlet of the liquid guiding chamber. The third water inlet of the liquid guiding chamber is connected to the liquid pump device. The third water outlet of the liquid guiding chamber is connected to the fourth water inlet of the foaming chamber. The air inlet of the foaming chamber is connected to the air pump device. The fifth water inlet of the foaming chamber is connected to the second water outlet of the water inlet chamber. The fourth water outlet of the foaming chamber is connected to the shower head.

[0006] One end of the water circuit switching valve is inserted into the water inlet chamber, and the other end is connected to the pressing device. The pressing device is used to drive the water circuit switching valve to move in the water inlet chamber. The water circuit switching valve is used to selectively open the first water outlet or the second water outlet.

[0007] The reed switch is electrically connected to the air pump device and the liquid pump device. The pressing device is equipped with a magnetic element, which moves synchronously with the pressing device to change the switching state of the reed switch.

[0008] The foaming shower machine provided in this application integrates a pressing device and a water path switching valve within the water inlet chamber. Through the interaction of the magnetic component on the pressing device and a reed switch, a single press of the device simultaneously switches the water flow from the clean water path to the foaming path, automatically activating the air pump and liquid pump required for foaming. Pressing the device again switches back to the clean water path and stops foaming. This application links the water path switching and foaming function activation / deactivation via the pressing device, water path switching valve, and reed switch. Users do not need to operate multiple buttons and valves separately; a single press is sufficient to activate or deactivate the complete foaming shower function, achieving a one-button, low-cost, highly reliable, and user-friendly foaming shower experience.

[0009] In one embodiment, the water circuit switching valve includes a first valve core and a piston. The first valve core has a sliding groove with openings at both ends, and the surface of the first valve core has a first through hole and a second through hole communicating with the sliding groove. The opening of the sliding groove at the end away from the pressing device is opposite to the first water inlet, the second through hole is opposite to the second water inlet, and the first through hole communicates with the foaming chamber.

[0010] The piston is movably disposed in the sliding groove and is connected to the pressing device. The pressing device drives the piston to move in the sliding groove and form at least a first position and a second position. When the piston is in the first position, the water inlet chamber, the first through hole, the sliding groove, the second through hole and the second water outlet are connected in sequence.

[0011] When the piston is in the second position, the inlet chamber, the first through hole, the sliding groove, and the first outlet are sequentially connected. Through the slide valve mechanism formed by the first valve core and the piston, the internal flow path of the water is precisely changed by using a pressing device to drive the piston to move within the sliding groove. When the piston is in the second position, the water flow is guided to the foaming chamber to achieve the foaming function; when the piston is in the first position, the water flow is directly to the shower head for ordinary showering. This slide valve design is compact and has good sealing performance, enabling reliable switching between the two water paths with minimal mechanical action.

[0012] In one embodiment, a first sealing ring is provided between the opening of the sliding groove at the end away from the pressing device and the second water inlet.

[0013] In one embodiment, the first through hole and the second through hole are spaced apart along the length of the sliding groove, a second sealing ring is provided on the surface of the first valve core between the first through hole and the second through hole, and a third sealing ring is provided on the end of the surface of the first valve core away from the first water inlet, and the second through hole is distributed between the second sealing ring and the third sealing ring.

[0014] In one embodiment, the pressing device employs a ballpoint pen-style spring-loaded structure to drive the piston to reciprocate between the first and second positions. Specifically, the pressing device is a ballpoint pen-style spring-loaded structure. This structure drives the piston to reciprocate between the first and second positions with each press and then locks itself in place. This design transforms the complex water circuit mode switching into a simple one-button operation. Furthermore, each operation ensures the piston accurately reaches and stabilizes in one of the positions, reliably connecting the clean water path or the foaming path. Simultaneously, the magnetic component mounted on it can precisely enter or leave the sensing area of ​​the reed switch as the piston moves, thereby achieving synchronous start and stop of the air pump and liquid pump devices with the water circuit switching.

[0015] In one embodiment, the pressing device includes a button, a first ratchet, a second ratchet, and an elastic element. The second ratchet is threaded to the water inlet cavity. The first ratchet is rotatably mounted on the button. One end of the piston is connected to the first ratchet, and one end of the elastic element is connected to the first ratchet, while the other end is connected to the piston. The first and second ratchets are adapted to each other. Through the coordinated action of the button, the first ratchet, the second ratchet, and the elastic element, the pressing device converts the user's pressing force into the rotation and linear motion of the first ratchet. Utilizing the engagement between the ratchets and the energy release of the elastic element, the piston is driven to achieve reliable reciprocating motion and self-locking between two stable positions.

[0016] In one embodiment, a flow valve is provided within the liquid guiding chamber. This flow valve is used to adjust the flow rate of clean water supplied from the water inlet chamber to the foaming chamber. By adding a flow valve to the liquid guiding chamber, the flow rate of clean water flowing from the water inlet chamber into the foaming chamber for mixing can be precisely controlled. This allows users to directly control the mixing ratio of water and foaming liquid during the foaming process, thereby achieving adjustment of the final foam concentration and meeting the personalized needs of different users for foam consistency.

[0017] In one embodiment, the flow valve includes a rotary handle and a second valve body. One end of the second valve body is inserted into the liquid guiding chamber, and the other end is connected to the rotary handle. A liquid delivery channel is formed within the second valve body. The fifth outlet of the liquid delivery channel communicates with the third outlet. The rotary handle drives the second valve body to rotate within the liquid guiding chamber to adjust the overlap between the sixth inlet of the liquid delivery channel and the second inlet. By rotating the handle, the flow valve drives the second valve body with the internal liquid delivery channel to rotate within the liquid guiding chamber. This rotation changes the overlap area between the sixth inlet of the liquid delivery channel and the second inlet of the liquid guiding chamber, thereby achieving flow regulation. This adjustment mechanism is simple and smooth to operate, providing precise flow control, allowing users to easily and precisely adjust the foam consistency, greatly improving the product's adjustability and user experience.

[0018] In one embodiment, the liquid guiding chamber is further provided with a drain outlet, and a drain valve is installed at the drain outlet. By adding a drain outlet with a drain valve to the liquid guiding chamber, this design allows for dynamic diversion of the water flow entering the liquid guiding chamber during foaming operations. A portion of the clean water enters the foaming chamber along a preset path to participate in foaming, while the excess is discharged in real time through the drain outlet. This ensures that the total water flow returning from the foaming shower to the main water circuit remains stable, thereby avoiding the flameout problem caused by excessively low inlet flow of the gas water heater due to foaming water intake. It also avoids the imbalance of hot and cold water pressure caused by insufficient flow in the foaming water circuit, ensuring a continuous supply of hot water and a comfortable experience during the foaming process.

[0019] In one embodiment, a timer and a control circuit board are also included. The timer, the reed switch, the air pump, and the liquid pump are electrically connected to the control circuit board. The timer receives a user-set time signal and outputs it to the control circuit board to control the foaming time. The control circuit board converts the user-set time signal into control over the operating time of the air pump and the liquid pump. This upgrades the foaming function from a manual mode relying on user touch to a preset automatic mode. Users can automatically start and stop the foaming without continuous operation, thereby accurately controlling the foaming amount, effectively saving water and foaming liquid, and improving the automation and ease of operation of the product.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0038] like Figures 1 to 8 As shown, this embodiment provides a foaming bath machine, including a foaming device 10, an air pump device 20, a liquid pump device 30, a water circuit switching valve 40, a pressing device 50, and a reed switch 60;

[0039] The foaming device 10 has an inlet chamber 101, a foaming chamber 102, and a liquid guiding chamber 103. The first inlet 1A of the inlet chamber 101 is connected to an external water source. The first outlet 1B of the inlet chamber 101 is connected to the second inlet 2A of the liquid guiding chamber 103. The third inlet 3A of the liquid guiding chamber 103 is connected to the liquid pump device 30. The third outlet 3B of the liquid guiding chamber 103 is connected to the fourth inlet 4A of the foaming chamber 102. The air inlet 1C of the foaming chamber 102 is connected to the air pump device 20. The fifth inlet 5A of the foaming chamber 102 is connected to the second outlet 2B of the inlet chamber 101. The fourth outlet 4B of the foaming chamber 102 is connected to the shower head.

[0040] One end of the water circuit switching valve 40 is inserted into the water inlet chamber 101, and the other end is connected to the pressing device 50. The pressing device 50 is used to drive the water circuit switching valve 40 to move in the water inlet chamber 101. The water circuit switching valve 40 is used to selectively open the first water outlet 1B or the second water outlet 2B.

[0041] The reed switch 60 is electrically connected to the air pump device 20 and the liquid pump device 30. The pressing device 50 is equipped with a magnetic element 55, which moves synchronously with the pressing device 50 to change the opening and closing state of the reed switch 60.

[0042] This application discloses a foaming bath machine, in which a pressing device 50 and a water path switching valve 40 are integrated within the water inlet chamber 101. Through the cooperation of the magnetic element 55 on the pressing device 50 and the reed switch 60, a single press of the pressing device 50 simultaneously switches the water flow from the clean water path to the foaming path, automatically activating the air pump 20 and liquid pump 30 required for foaming. Pressing the pressing device 50 again switches back to the clean water path and stops foaming. This application links the water path switching and foaming function activation / deactivation via the pressing device 50, water path switching valve 40, and reed switch 60. Users do not need to operate multiple buttons 51 and valves separately; a single press is sufficient to activate or deactivate the complete foaming bath function, achieving a one-button, low-cost, highly reliable, and user-friendly foaming bath experience.

[0043] The air pump device 20 can be used to deliver gas, such as air, to the foaming chamber 102; the liquid pump device 30 can be used to deliver cleaning liquid, such as shampoo or shower gel, to the foaming chamber 102 through the liquid guiding chamber 103.

[0044] The water circuit switching valve 40 can be used to selectively open the first outlet 1B or the second outlet 2B. Specifically, when the first outlet 1B is open and the second outlet 2B is closed, external clean water enters the inlet chamber 101 from the first inlet 1A. The clean water enters the foaming path and flows sequentially through the first outlet 1B and the second inlet 2A into the liquid guiding chamber 103 to mix with the cleaning liquid. The mixture is then transported to the foaming chamber 102 to mix with the gas for foaming, and finally the foam is discharged from the fourth outlet 4B. When the first outlet 1B is closed and the second outlet 2B is open, external clean water enters the inlet chamber 101 from the first inlet 1A. The clean water enters the clean water path and flows sequentially through the second outlet 2B and the fifth inlet 5A into the foaming chamber 102, and finally the clean water is discharged from the fourth outlet 4B.

[0045] The pressing device 50 can be used to drive the water circuit switching valve 40 to move relative to the inlet chamber 101, so as to selectively open the first outlet 1B or the second outlet 2B.

[0046] The reed switch 60 can be used to control the on / off state of the air pump device 20 and the liquid pump device 30. The working state of the reed switch 60 is determined by the position of the magnetic element 55 on the pressing device 50. Specifically, when the pressing device 50 is displaced, it causes the magnetic element 55 to be displaced relative to the reed switch 60, thereby changing the magnetic attraction force on the reed switch 60, causing the contacts inside the reed switch 60 to close, generating a start signal to trigger the air pump device 20 and the liquid pump device 30 to work.

[0047] In one embodiment, such as Figure 4 , Figure 7 and Figure 8As shown, the water circuit switching valve 40 includes a first valve core 41 and a piston 42. The first valve core 41 has a sliding groove 401 with openings at both ends. The surface of the first valve core 41 is provided with a first through hole 1E and a second through hole 2E that communicate with the sliding groove 401. The opening of the sliding groove 401 at the end away from the pressing device 50 is opposite to the first water inlet 1A. The second through hole 2E is opposite to the second water inlet 2A. The first through hole 1E communicates with the foaming chamber 102.

[0048] Piston 42 is movably disposed in sliding groove 401 and is connected to pressing device 50. Pressing device 50 drives piston 42 to move in sliding groove 401 and form at least a first position and a second position. When piston 42 is in the first position, water inlet chamber 101, first through hole 1E, sliding groove 401, second through hole 2E and second outlet 2B are connected in sequence.

[0049] When the piston 42 is in the second position, the water inlet chamber 101, the first through hole 1E, the sliding groove 401 and the first water outlet 1B are connected in sequence.

[0050] The above embodiment further defines the slide valve mechanism composed of the first valve core 41 and the piston 42. The piston 42 is driven by the pressing device 50 to move within the sliding groove 401, precisely changing the internal flow path of the water. When the piston 42 is in the second position, the water flow is guided to the foaming chamber 102 to achieve the foaming function; when the piston 42 is in the first position, the water flow directly to the shower head for ordinary showering. This slide valve design is compact and has good sealing performance, enabling reliable switching between the two water paths with minimal mechanical action.

[0051] The first valve core 41 has a sliding groove 401 inside and a first through hole 1E and a second through hole 2E. Clean water enters the water inlet chamber 101 through the first water inlet 1A and enters the sliding groove 401 through the first through hole 1E. The clean water enters the liquid guiding chamber 103 through the first water outlet 1B in the sliding groove 401, and can also enter the foaming chamber 102 through the second through hole 2E.

[0052] Piston 42 can be a component that moves within the sliding groove 401, and its position determines whether the first outlet 1B or the second outlet 2B is open. Specifically, the piston can slide relative to the sliding groove 401 and form at least a first position and a second position. When piston 42 is driven to the first position by pressing device 50, water from the first inlet 1A enters the sliding groove 401 and cannot flow directly out of the first outlet 1B. The water is forced to flow out through the second through hole 2E and enter the foaming chamber 102, thereby directly outputting clean water. When piston 42 is in the second position, piston 42 blocks the path between the first through hole 1E and the second through hole 2E. Thus, after water from the first inlet 1A enters the sliding groove 401, it flows through the first outlet 1B to the liquid guiding chamber 103 to mix with the cleaning liquid. Then, the mixture of clean water and cleaning liquid is transported to the foaming chamber 102 to mix with gas for foaming.

[0053] In one embodiment, such as Figure 4 and Figure 7 As shown, a first sealing ring 71 is provided between the opening of the sliding groove 401 away from the pressing device 50 and the second water inlet 2A.

[0054] In one embodiment, such as Figure 4 and Figure 7 As shown, the first through hole 1E and the second through hole 2E are distributed at intervals along the length direction of the sliding groove 401. A second sealing ring 72 is provided on the surface of the first valve core 41 between the first through hole 1E and the second through hole 2E, and a third sealing ring 73 is provided on the end of the surface of the first valve core 41 away from the first water inlet 1A. The second through hole 2E is distributed between the second sealing ring 72 and the third sealing ring 73.

[0055] In one embodiment, such as Figure 4 and Figure 8 As shown, the pressing device 50 adopts a ballpoint pen-style spring-loaded structure to drive the piston 42 to reciprocate in the first and second positions.

[0056] The above embodiment further specifies that the pressing device 50 is a ballpoint pen-style spring-loaded structure. This structure drives the piston 42 to move back and forth between the first and second positions and lock itself with each press. This design transforms the complex water circuit mode switching into a simple one-button operation. Moreover, each operation allows the piston 42 to accurately reach and stabilize in one of the positions, thereby reliably connecting the clean water path or the foaming path. At the same time, the magnetic component 55 installed on it can also accurately enter or leave the sensing area of ​​the reed switch 60 as the piston 42 moves, thereby realizing the synchronous start and stop of the air pump device 20 and the liquid pump device 30 with the water circuit switching.

[0057] In one embodiment, such as Figure 4 and Figure 8As shown, the pressing device 50 includes a button 51, a first ratchet 52, a second ratchet 53, and an elastic element 54. The second ratchet 53 is connected to the water inlet chamber 101 by a thread. The first ratchet 52 is rotatably mounted on the button 51. One end of the piston 42 is connected to the first ratchet 52. One end of the elastic element 54 is connected to the first ratchet 52, and the other end is connected to the piston 42. The first ratchet 52 and the second ratchet 53 are adapted to each other.

[0058] The above embodiments further define that the pressing device 50, through the coordinated action of the button 51, the first ratchet 52, the second ratchet 53 and the elastic element 54, converts the user's pressing force into the rotation and linear motion of the first ratchet 52, and utilizes the engagement between the ratchets and the energy storage and release of the elastic element 54 to drive the piston 42 to achieve reliable reciprocating motion and self-locking between two stable positions.

[0059] In one embodiment, such as Figure 5 As shown, a flow valve 80 is provided in the liquid guiding chamber 103. The flow valve 80 is used to adjust the flow rate of clean water delivered from the water inlet chamber 101 to the foaming chamber 102.

[0060] The above embodiment further specifies that a flow valve 80 is added in the liquid guiding chamber 103 to precisely control the flow rate of clean water flowing from the water inlet chamber 101 into the foaming chamber 102 for mixing. This allows users to directly control the mixing ratio of water and foaming liquid during the foaming process, thereby achieving adjustment of the final foam concentration and meeting the personalized needs of different users for foam consistency.

[0061] like Figure 5 As shown, the flow valve 80 includes a rotary handle 81 and a second valve body 82. One end of the second valve body 82 is inserted into the liquid guiding chamber 103, and the other end is connected to the rotary handle 81. A liquid delivery channel 801 is formed in the second valve body 82. The fifth outlet 5B of the liquid delivery channel 801 is connected to the third outlet 3B. The rotary handle 81 drives the second valve body 82 to rotate in the liquid guiding chamber 103 to adjust the overlap between the sixth inlet 6A and the second inlet 2A of the liquid delivery channel 801.

[0062] The above embodiment further defines the flow valve 80, which drives the second valve body 82, which has an internal infusion channel 801, to rotate within the liquid guiding chamber 103 by rotating the handle 81. The rotation of the second valve body 82 changes the overlapping area of ​​the sixth inlet 6A of the infusion channel 801 and the second inlet 2A of the liquid guiding chamber 103, thereby achieving flow regulation. Moreover, this regulation mechanism is simple and smooth to operate, and can provide precise flow control, allowing users to easily and finely adjust the foam consistency, greatly improving the product's adjustability and user experience.

[0063] In one embodiment, such as Figure 6 and Figure 7As shown, the liquid guiding cavity 103 is also provided with a drain port 1D, and a drain valve is provided at the drain port 1D.

[0064] The above embodiment further specifies that the liquid guiding chamber 103 is equipped with a drain outlet 1D with a drain valve. This design can dynamically divert the water flow entering the liquid guiding chamber 103 during the foaming operation. A portion of the clean water enters the foaming chamber 102 along a preset path to participate in foaming, while the excess portion is discharged in real time through the drain outlet 1D. This ensures that the total water flow from the foaming shower machine back to the main water circuit remains stable, thereby avoiding the flameout problem caused by the low inlet flow of the gas water heater due to foaming water intake. At the same time, it avoids the imbalance of hot and cold water pressure caused by the low flow of the foaming water circuit, ensuring a continuous supply of hot water and a comfortable experience during the foaming process.

[0065] In one embodiment, such as Figure 1 As shown, it also includes a timer 90 and a control circuit board. The timer 90, reed switch 60, air pump device 20 and liquid pump device 30 are electrically connected to the control circuit board. The timer 90 is used to receive the user's time setting signal and output it to the control circuit board to control the foaming time.

[0066] The above embodiments further define the control circuit board as converting the user-set time signal into control of the operating time of the air pump device 20 and the liquid pump device 30. This upgrades the foaming function from a manual mode that relies on user touch to a preset automatic mode. Users can achieve automatic start and stop of foaming without continuous operation, thereby accurately controlling the foaming amount, effectively saving water and foaming liquid, and improving the automation level and ease of operation of the product.

[0067] The timer 90 can be a knob, button, or digital panel to set the desired foaming time. Specifically, when the user presses the pressing device 50, the reed switch 60 changes state and sends a start signal to the control circuit board. Upon receiving the signal from the reed switch 60, the control circuit board immediately drives the air pump device 20 and the liquid pump device 30 to start working and simultaneously starts the timer. When the user-preset time is reached, the control circuit board automatically cuts off the power to the air pump device 20 and the liquid pump device 30, and the foaming function stops.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
