Description

[0001] This application claims priority to Chinese Patent Application No. 2024119717109, filed on December 30, 2024, entitled "Small Bubble Facial Massager with Press-Type Water Tank", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of beauty and skin care equipment, specifically to a microbubble facial device with a press-type water tank. Background Technology

[0003] In the current facial cleansing market, microbubble cleansing is widely popular. It utilizes a special solution to form tiny bubbles that penetrate deep into pores to absorb dirt and oil. For example, a Chinese utility model patent (publication number: CN217244022U) provides a cleansing head for a bubble cleanser with a rotating brush head. This application uses a motor and a first connecting shaft to allow the brush head to rotate relative to the outer shell, thus rubbing the user's skin. The protruding parts enhance the brush head's cleaning ability. An external water pump pumps water into the inlet chamber, which connects to the outlet channel, allowing water to flow from the brush head. The external water pump also connects to the suction hole through a first return channel to remove wastewater. Positioning the outlet channel on the first connecting shaft ensures that the rotation of the brush head does not affect the flow of clean water.

[0004] However, currently available microbubble facial devices on the market will continue to squeeze out liquid from the brush head due to excessively high liquid pressure in the water channel from the time of use until the device is stopped. Even after the water pump is turned off, some cleaning liquid will still flow out from the head of the facial device. This liquid will remain in the facial device and cause stains, and may even cause skin problems due to bacterial growth. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a microbubble facial device with controllable liquid output to overcome the above-mentioned disadvantages.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a microbubble facial device with controllable liquid output, including a handheld rod and a base; the handheld rod is defined with a first direction, a second direction, and a third direction, which intersect each other; the handheld rod has a first end and a second end opposite to each other in the first direction; the handheld rod has a third end and a fourth end opposite to each other in the second direction; the handheld rod has a fifth end and a sixth end opposite to each other in the third direction; a mounting head is provided at the first end, and a housing cover is detachably provided on the mounting head; the housing cover has a contact opening, and a receiving cavity is provided inside the housing cover, in which a cleaning head is rotatably disposed, and the cleaning head is exposed through the contact opening; the mounting head has a liquid inlet and a liquid outlet; when the handheld rod is placed on the base, in the second direction, the liquid inlet is closer to the third end than the liquid outlet; it also includes: a second driving device for driving the flow of cleaning liquid, the input port of the second driving device being connected to the liquid outlet through a conduit.

[0007] In some embodiments, the mounting head includes an end face that intersects the first direction; both the liquid inlet and the liquid outlet are located on the end face.

[0008] In some embodiments, the end face extends from the edge toward the center while also extending toward the second end to form an inclined conical surface.

[0009] In some embodiments, an annular drainage groove is formed by recessing the center of the end face in the negative direction of the first direction, and the drainage groove is arranged around the axis of the cleaning head.

[0010] In some embodiments, a straight drainage channel is further provided on the end face, one end of the straight drainage channel is connected to the annular drainage channel, the other end of the straight drainage channel extends toward the fourth end, and the drain port is located inside the straight drainage channel.

[0011] In some embodiments, the linear drainage channel includes a first linear drainage channel and a second linear drainage channel. The first linear drainage channel extends toward the fourth end and also toward the fifth end; the second linear drainage channel extends toward the fourth end and also toward the sixth end.

[0012] In some embodiments, the drain outlet includes a first drain outlet and a second drain outlet, wherein the first drain outlet is located inside the first straight drainage channel and the second drain outlet is located inside the second straight drainage channel.

[0013] In some embodiments, the line connecting the inlet and the outlet is parallel to the second direction.

[0014] In some embodiments, the second drive device is disposed inside the base, and the base is also provided with a wastewater tank. The output port of the second drive device is connected to the wastewater tank through a conduit.

[0015] In some embodiments, the shell cover and the mounting head are sealed. When the contact opening comes into contact with the skin, the receiving cavity forms a closed cavity. Under the drive of the second driving device, the drain port generates negative pressure, and the cleaning fluid passively enters the receiving cavity from the inlet.

[0016] In summary, the present invention has the following beneficial effects: the device of the present invention has the liquid inlet close to the upper end and the liquid outlet close to the lower end, which enables the liquid in the receiving cavity to automatically flow to the area where the liquid outlet is located, so that the liquid can be absorbed in time and the facial device can be kept dry and clean.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] This invention relates to a microbubble facial device with a press-type water tank, which is a beauty and skin care product. It can output microbubbles with a rotating function and can be used with special solutions or cleansing solutions. Under the drive of a pressure pump, it forms microbubbles, which can act on the skin surface after being output to achieve the effect of beauty care.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] For ease of description, such as Figure 2 As shown, firstly, based on the handheld lever 1, each direction is defined as follows: A1A2 is the first direction, the direction where A1 is located is the negative direction of the first direction, and the direction where A2 is located is the positive direction of the first direction; B1B2 is the second direction, the direction where B1 is located is the negative direction of the second direction, and the direction where B2 is located is the positive direction of the second direction; C1C2 is the third direction, the direction where C1 is located is the negative direction of the third direction, and the direction where C2 is located is the positive direction of the third direction; the first direction, the second direction, and the third direction intersect each other.

[0024] Figure 1 The diagram schematically illustrates a microbubble facial massager with a press-type water tank according to one embodiment of the present invention. The massager includes a handheld handle 1 and a base 2. The handheld handle 1 is the main component for the user to hold and apply to the skin. The base 2 is an auxiliary device that matches the handheld handle 1. The base 2 and the handheld handle 1 are connected by an integrated connecting cable (not shown in the figure). The integrated connecting cable contains metal wires for power supply and conduits for water supply. Using an integrated connecting cable improves the integration of the device, facilitates maintenance, and avoids overly complex device structures that could affect normal use.

[0025] like Figure 2 , Figure 3As shown, the handheld lever 1 has an outer shell 11 for the operator to grip. To improve grip comfort, the outer shell 11 is generally strip-shaped. The interior of the outer shell 11 is hollow to accommodate and protect functional equipment. The outer shell 11 is equipped with hardware structures such as a switch 113 for starting. The axial direction of the outer shell 11 is generally parallel to the first direction. The outer shell 11 is divided into a first end and a second end along the axial direction. The first end is a free end for contact with human skin, and the second end is a controlled end, equipped with a first connecting wire 12 to fix the integrated connecting wire and guide it into the interior of the outer shell 11 to achieve water and electricity supply. The handheld lever 1 has a third end (B1 direction) and a fourth end (B2 direction) in the second direction, and a fifth end (C1 direction) and a sixth end (C2 direction) in the third direction.

[0026] like Figure 2 , Figure 3 As shown, the handheld rod 1 also includes a cleaning head 15 and a cover 14. The cleaning head 15 is used to clean the facial skin. The outer rod shell 11 includes a first outer shell 111, a second outer shell 112, and a mounting head 13. The first outer shell 111 and the second outer shell 112 are both strip-shaped and extend along the axial direction to form the main body of the outer rod shell 11. The mounting head 13 is snapped into the first end of the outer rod shell 11. The mounting head 13 has a portion exposed on the outer rod shell 11 for detachably connecting the cover 14. The cover 14 is detachably connected to the mounting head 13 through a snap-fit ​​structure. The cover 14 has a hollow structure with an internal cavity 141. The cover 14 also has a contact opening 142 through which the cleaning head 15 is exposed to contact the skin.

[0027] like Figure 4 , Figure 5 , Figure 6As shown, in some embodiments, the cover 14 is generally funnel-shaped, and the flared end of the cover 14 is connected to the mounting head 13. In the positive direction of the first direction, the diameter of the cover 14 gradually decreases until it is reduced to the diameter of the contact opening 142. The mounting head 13 is provided with at least one first connecting part 135, which is located on the outer side wall of the mounting head 13. In some embodiments, there are two or three first connecting parts 135, which are evenly distributed around the outer side wall of the mounting head 13. The inner side of the cover 14 is provided with a second connecting part 143, the number of which is equal to the number of the first connecting parts 135, and in the circumferential direction, the positions of the second connecting parts 143 correspond one-to-one with the positions of the first connecting parts 135. Preferably, there are two first connecting portions 135, each with a groove structure and an L-shaped structure. Each first connecting portion 135 includes a first limiting groove 1351 and a second limiting groove 1352, which are connected sequentially. The first limiting groove 1351 is axially arranged along the outer side wall of the mounting head 13, and the second limiting groove 1352 is circumferentially arranged along the outer side wall of the mounting head 13. There are also two second connecting portions 143, each with a protruding structure. After the second connecting portions 143 and the first connecting portions 135 are aligned one-to-one, the cover 14 is first moved in the negative direction of the first direction, causing the second connecting portion 143 to move along the first limiting groove 1351 to the bottom end of the first connecting portion 135. Then, the cover 14 is rotated circumferentially, causing the second connecting portion 143 to move along the second limiting groove 1352 to the very end of the first connecting portion 135. At this point, due to the L-shaped structure of the first connecting part 135, the second connecting part 143 loses its axial degree of freedom to complete the connection between the cover 14 and the mounting head 13. Furthermore, to prevent the cover 14 from rotating and falling off during use, a first engaging part 1353 is provided inside the first connecting part 135. The first engaging part 1353 is specifically located near the end of the second limiting groove 1352. A second engaging part 144 is provided on the second connecting part 143. The first engaging part 1353 can cooperate with the second engaging part 144 to restrict the circumferential degree of freedom of the cover 14. Preferably, the first engaging portion 1353 is a cylindrical structure and is arranged along the first direction. The second engaging portion 144 is a groove structure and extends along the first direction. When the second connecting portion 143 rotates circumferentially with the cover 14, the first engaging portion 1353 engages with the interior of the second engaging portion 144 to achieve engagement, thereby improving the connection stability between the cover 14 and the mounting head 13.

[0028] like Figure 4 , Figure 5As shown, in some embodiments, the mounting head 13 is provided with a positioning groove 133. The positioning groove 133 is arranged circumferentially and surrounds the outer wall of the mounting head 13. A sealing ring 134 is accommodated inside the positioning groove 133. The cross-sectional diameter of the sealing ring 134 is larger than the depth of the positioning groove 133, so that the sealing ring 134 partially protrudes from the positioning groove 133. When the cover 14 and the mounting head 13 are connected to each other, the inner sidewall of the cover 14 and the sealing ring 134 are pressed against each other to form a sealing structure. The sealing ring 134 is surrounded inside the cover 14 and is not exposed to the outside, so that a sealed connection is formed between the cover 14 and the mounting head 13. The receiving cavity 141 inside the cover 14 can only communicate with the outside through the contact opening 142.

[0029] like Figure 3 , Figure 6 , Figure 7 As shown, the cleaning head 15 is housed inside the receiving cavity 141. The cleaning head 15 includes a brush disc 151 and a connecting sleeve 153. The brush disc 151 is circular, and the contact opening 142 is also circular. The brush disc 151 and the contact opening 142 are arranged coaxially, and the diameter of the brush disc 151 matches the diameter of the contact opening 142, ensuring that the bristles 152 can be exposed through the contact opening 142 and that the brush disc 151 does not interfere with the inner wall of the contact opening 142. A plurality of bristles 152 are provided on the side of the brush disc 151 facing the contact opening 142. The connecting sleeve 153 is fixedly connected to the other side of the brush disc 151. The connecting sleeve 153 is used to connect to the drive end of the first driving device. The drive end of the first driving device drives the brush disc 151 to rotate through the connecting sleeve 153, and the bristles 152 rotate synchronously, thereby rubbing and cleaning the skin area in contact. Preferably, the bristles 152, the brush disc 151, and the connecting sleeve 153 are all made of soft silicone to avoid damage to the skin tissue. Because facial skin has varying contours, the connection between the cleaning head 15 and the first drive device is detachable to accommodate different areas. Users can select different sized cleaning heads 15 depending on the area being cleaned. For example, smaller cleaning heads 15 can be used for smaller areas such as the nasal wings, bridge of the nose, and corners of the eyes, while larger cleaning heads 15 can be used for flatter areas such as the cheeks and forehead. The cover 14 also needs to be replaced according to the size of the cleaning head 15. The ends of the bristles 152 are on the same plane as the contact opening 142, ensuring that the ends of the bristles 152 also contact the skin when the edge of the contact opening 142 is in contact with the skin. In some embodiments, the bristles 152 on the brush plate 151 can be adaptively adjusted according to different models. For example, the shape and arrangement of the bristle ends, the material, length, and diameter of the bristles 152 can all be selected according to actual needs.

[0030] like Figure 4 , Figure 5As shown, to perform deep facial cleansing, a cleaning solution needs to be supplied to the cleansing head 15. When the cleansing head 15 rotates, the cleaning solution provides lubrication between the head and the skin, effectively removing oil from the skin. The rotation of the head 15 also generates tiny bubbles for deeper skin cleansing. The amount of cleaning solution in the facial device should not be excessive to avoid spillage and affecting the user experience; therefore, used solution should be promptly removed. The mounting head 13 has an inlet 131 and an outlet. The inlet 131 is connected to the water tank 24 in the base 2 via a conduit to release the cleaning solution into the receiving cavity 141. The outlet is connected to the waste water tank 25 in the base 2 via a conduit to remove waste solution from the receiving cavity 141, preventing accumulation and ensuring a better user experience. In some embodiments, the inlet 131 is a passive, unpowered type, while the outlet is an active suction type. When the contact opening 142 is in contact with the skin and sealed, the cavity 141 is sealed. The suction effect of the outlet reduces the pressure in the cavity 141, and the cleaning fluid in the inlet 131 passively flows into the cavity 141. When the contact opening 142 separates from the skin and opens, the pressure inside the cavity 141 does not change due to the active suction of the outlet. Therefore, the cleaning fluid in the inlet 131 will not remain in the cavity 141, and any residual waste fluid in the cavity 141 will be discharged from the outlet under suction. With the above structure, the flow of the cleaning fluid can be controlled by simply controlling the contact state between the contact opening 142 and the skin, effectively preventing the cleaning fluid from flowing out when not in use.

[0031] During the actual cleaning process, the cleaning fluid can flow to the area near the bristles 152. As the bristles 152 rotate, they can mix with the cleaning fluid to generate dense small bubbles. These small bubbles can interact with the skin pores to deeply clean the oil in the skin. There is also a gap between the brush plate 151 and the inner wall of the cover 14. The cleaning fluid flowing out from the inlet 131 can flow through the gap to the bristles 152. As the bristles 152 rotate, they will generate a certain centrifugal force. The liquid swept by the bristles 152 becomes waste liquid and flows a short distance along the inner wall of the cover 14 towards the second end 1b. Then, it is sucked away from the receiving cavity 141 by the suction of the drain port. In actual use, the person being cared for is lying down with their face facing upwards. The operator holds the facial device to clean the person's face. During use, the handheld rod 1 is held with the first end facing down and the second end facing up (i.e., A1 direction facing down and A2 direction facing up). With the contact opening 142 facing down, it contacts the facial skin. By applying slight force, the contact opening 142 is pressed tightly against the facial skin, forming a sealed structure in the receiving cavity 141 using the facial skin. At this time, the suction function of the drain port is turned on, and the cleaning head 15 starts to rotate simultaneously. The air pressure inside the receiving cavity 141 decreases, and the cleaning liquid in the inlet 131 flows into the receiving cavity 141. Under the action of gravity, it flows to the position of the brush bristles 152 of the cleaning head 15. The rotating cleaning head 15 uses the cleaning liquid to brush and clean the skin. Under the action of centrifugal force, the waste liquid flows upwards along the inner wall of the shell 14 and is sucked out of the receiving cavity 141 by the drain port.

[0032] like Figure 3 , Figure 8 , Figure 9As shown, in some embodiments, the first driving device includes: a circuit board 161, a motor sleeve 162, a bearing plate 163, a motor, a connecting shaft 165, and a connector 166. The motor sleeve 162 has a cylindrical structure and is confined within the outer rod housing 11. The bearing plate 163 is mounted on the mounting head 13 and is used to fix the bearing 1631, which is housed within the mounting head 13. The motor sleeve 162 is fixedly connected to the bearing plate 163. The motor includes a motor body 1641 and a drive shaft 1642. The circuit board 161 is disposed inside the handheld lever 1 and is used to integrate control circuitry. The motor (not shown) obtains power through connection to the circuit board 161. The motor body 1641 is mounted on the motor sleeve 162, and the drive shaft 1642 extends within the motor sleeve 162. The motor sleeve 162 covers a portion of the connecting shaft 165, allowing the connecting shaft 165 to be rotatably disposed within the motor sleeve 162. One end of the connecting shaft 165 is connected to the drive shaft 1642 of the motor. 2. The connecting shaft 165 serves as an extension of the motor drive end and is used to cooperate with the connector 166 to transmit power. The other end of the connecting shaft 165 passes through the bearing plate 163 and is exposed on the mounting head 13. The bearing 1631 on the bearing plate 163 is used to support the connecting shaft 165 and enable the connecting shaft 165 to rotate around its axis. The connector 166 is sleeved on the exposed end of the connecting shaft 165 and is used to detachably connect the cleaning head 15, so that the connecting shaft 165 can drive the cleaning head 15 to rotate and can be disassembled and replaced.

[0033] like Figure 10 As shown, the connector 166 has a mating hole 1661, forming an annular structure. The mating hole 1661 is a through hole with a contact surface inside, allowing it to be inserted into the shaft end of the connecting shaft 165. When the connecting shaft 165 rotates, it drives the connector 166 to rotate, causing the cleaning head 15 to rotate. The connecting sleeve 153 of the cleaning head 15 is sleeved on the connector 166. The connecting sleeve 153 is also made of soft silicone material. The connecting sleeve 153 is sleeved on the connector 166 through expansion deformation, and is fixed by mutual compression between its retraction force and the outer surface of the connector 166. To prevent relative sliding between the connector 166 and the cleaning head 15, the side wall of the connector 166 is provided with a fixing mark 1662 and a fixing surface 1663. The fixing mark 1662 is an uneven strip structure to increase the friction between the connector 166 and the connecting sleeve 153. The fixing mark 1662 covers the fixing surface 1663, which causes the connector 166 to form a folded edge, so that the cleaning head 15 can be rotated by force. Therefore, the cleaning head 15 is detachably connected by friction with the connector 166, making it easy to replace the cleaning head 15.

[0034] like Figure 4 , Figure 5As shown, the mounting head 13 further has an end face 136 at its exposed end, and the plane containing the end face 136 intersects the first direction, preferably perpendicular to the first direction. Both the inlet 131 and the outlet 131 are located on the end face 136. When the cover 14 mates with the mounting head 13, the inlet 131 and the outlet 131 are not obstructed by the cover 14. This ensures that the cleaning fluid can smoothly enter and exit the receiving cavity 141.

[0035] like Figure 4 , Figure 5 As shown, end face 136 is not a planar structure, but an inclined conical surface with a central concavity. That is, while end face 136 extends from the edge to the center, it also extends towards the second end. When viewed along the negative direction of the first direction, end face 136 appears as a concave structure. When the handle 1 is not in use and is placed on the base 2, the cleaning fluid located at the edge of end face 136 can flow along the inclined concave structure to the center and converge. An annular drainage groove 137, formed by a concavity along the negative direction of the first direction, is also provided in the center of end face 136. The annular drainage groove 137 is coaxially arranged around the cleaning head 15, and the cleaning fluid flowing from all sides along the inclined end face 136 will converge into the annular drainage groove 137 for automatic collection. To guide the cleaning fluid in the annular drainage channel 137 towards the drain port, a straight drainage channel is also provided on the end face 136. One end of the straight drainage channel is connected to the annular drainage channel 137, and the other end of the straight drainage channel extends towards the fourth end. The drain port is also housed inside the straight drainage channel, and the drain port is closer to the fourth end. The cleaning fluid guided by the straight drainage channel will flow towards the fourth end under the action of gravity, and thus the cleaning fluid will be closer to the drain port and be sucked away by the drain port.

[0036] like Figure 4 , Figure 5As shown, the drain outlet includes a first drain outlet 1321 and a second drain outlet 1322. The straight drainage channel also includes a first straight drainage channel 1381 and a second straight drainage channel 1382. The first straight drainage channel 1381 extends towards the fourth end and also towards the fifth end. The second straight drainage channel 1382 extends towards the fourth end and also towards the sixth end. That is, in the third direction, the first straight drainage channel 1381 and the second straight drainage channel 1382 will extend in opposite directions respectively. In this way, even if the cleaning liquid on the end face 136 does not converge into the annular drainage channel 137, it will fall into the interior of the straight drainage channel when it flows downward under the action of gravity. When the handheld lever 1 is not in use and is placed on the base 2, the connecting line between the axis of the inlet 131 and the axis of the second outlet 1322 is parallel to the second direction, that is, the inlet 131 is located directly above the second outlet 1322. The cleaning fluid flowing out of the inlet 131 will flow into the annular drainage groove 137 under the action of gravity, or it will flow directly to the vicinity of the second outlet 1322 located directly below it under the action of gravity. The liquid located near the first outlet 1321 and / or the second outlet 1322 will be sucked away under the negative pressure generated by the second drive device 23.

[0037] like Figure 12 As shown, to provide a detailed description of base 2, the directions of base 2 are first explained: Directions D1 and D2 are the fourth direction, where D1 is the positive direction and D2 is the negative direction; directions E1 and E2 are the fifth direction, where E1 is the positive direction and E2 is the negative direction; directions F1 and F2 are the sixth direction, where F1 is the positive direction and F2 is the negative direction. The fourth, fifth, and sixth directions intersect. When base 2 is placed on a horizontal surface, direction E2 is in the same direction as gravity.

[0038] In the fourth direction, the base 2 has a seventh end 2a and an eighth end 2b opposite to each other; in the fifth direction, the base 2 has a ninth end 2c and a tenth end 2d opposite to each other.

[0039] like Figure 12As shown, the base 2 mainly includes: an inclined panel 21 and a bottom shell 22 for supporting the inclined panel 21; the inclined panel 21 is provided with a fixing part 211 for placing the handheld lever 1, the fixing part 211 has a shape that fits the handheld lever 1, and when the handheld lever 1 is not in use, the handheld lever 1 can be placed on the fixing part 211 for storage. One side of the bottom shell 22 has an inclined first opening 221, which opens towards the eighth end to facilitate the assembly of parts inside the bottom shell 22. The inclined panel 21 is adapted to the edge of the first opening 221. When assembly is completed, the inclined panel 21 covers the first opening 221 to form a fixed connection, and also provides protection for the components inside the bottom shell 22. A second connecting wire head 222 is provided on the bottom shell 22. The second connecting wire head 222 is used to guide the integrated connecting wire into the interior of the bottom shell 22 for fixing, and also to protect the integrated connecting wire from excessive bending and damage.

[0040] like Figure 13 , Figure 14 As shown, a second driving device 23, a water storage tank 24, a wastewater tank 25, and a water tank fixing component 26 are also provided in the internal space of the bottom shell 22. The water storage tank 24 is used to store cleaning fluid, and the wastewater tank 25 is used to store waste liquid returned after cleaning. The second driving device 23 includes an input end and an output end. The input end is connected to the drain port on the mounting head 13 to draw waste liquid from the receiving cavity 141. The output end is connected to the wastewater tank 25 to discharge waste liquid into the wastewater tank 25. The water storage tank 24 is connected to the inlet 131 of the mounting head 13 via a conduit. The suction action of the second driving device 23 reduces the pressure inside the receiving cavity 141, allowing the cleaning fluid in the water storage tank 24 to passively flow into the receiving cavity 141 under negative pressure. In this embodiment, the second driving device 23 is specifically a pressure pump capable of generating negative pressure to draw waste liquid from the receiving cavity 141 of the handheld lever 1.

[0041] like Figure 14 As shown, the bottom shell 22 is also provided with a second opening 223 and a third opening 224. To avoid conflict with the first opening 221, the opening directions of the second opening 223 and the third opening 224 face the seventh end. The water tank 24 can be inserted into the base 2 for fixation through the second opening 223, and the wastewater tank 25 can be inserted into the base 2 for fixation through the third opening 224. The water tank fixing component 26 has a shell structure. The water tank fixing component 26 is fixed to the inner wall of the bottom shell 22 by screws or by a snap-fit ​​structure. The water tank fixing component 26 is used to provide positioning and quick connection for the water tank 24 and the wastewater tank 25. The water tank 24 can enter the interior of the water tank fixing component 26 through the second opening 223, and the wastewater tank 25 can enter the interior of the water tank fixing component 26 through the third opening 224.

[0042] like Figure 14 As shown, the internal space of the water tank fixing member 26 matches the shapes of the water storage tank 24 and the wastewater tank 25, respectively. When the water storage tank 24 enters the interior of the water tank fixing member 26 through the second opening 223, the water storage tank 24 can only slide in the fourth direction due to the matching shape. Similarly, when the wastewater tank 25 enters the interior of the water tank fixing member 26 through the third opening 224, the wastewater tank 25 can also only slide in the fourth direction due to the matching shape.

[0043] like Figure 19 , Figure 20 , Figure 21 , Figure 22 As shown, a pressing and positioning structure is also provided inside the base 2 to limit the movement of the water tank. There are two pressing and positioning structures, which are used to fix the water storage tank 24 and the wastewater tank 25 respectively. On the side of the water storage tank 24, when the water storage tank 24 passes through the second opening 223 and enters the water tank fixing member 26, pressure is applied to the water storage tank 24 in the negative direction of the fourth direction. Under the action of the pressing and positioning structure, the water storage tank 24 is connected to the water tank fixing member 26, and the water storage tank 24 loses its freedom in the fourth direction, achieving complete fixation. When it is necessary to remove the water storage tank 24, pressure is applied to the water storage tank 24 again in the negative direction of the fourth direction. The pressing and positioning structure can then cancel the fixing effect on the water storage tank 24, allowing the water storage tank 24 to move in the positive direction of the fourth direction and be pulled out from the second opening 223. Similarly, on one side of the wastewater tank 25, the wastewater tank 25 can also be stably connected to the water tank fixing part 26 under the action of the pressing and positioning structure, or be separated from the water tank fixing part 26, so that the wastewater tank 25 can be pulled out from the base 2.

[0044] like Figure 19 , Figure 20 As shown, the pressing and positioning structure includes a first connecting component and a second connecting component; wherein the first connecting component is fixedly mounted on the water tank 24 or wastewater tank 25, and the second connecting component is fixedly mounted on the water tank fixing member 26. When installing the water tank 24 or wastewater tank 25 into the base 2, pressure needs to be applied to the water tank 24 or wastewater tank 25 in the negative fourth direction, and the first connecting component and the second connecting component will cooperate to achieve connection. When separating the water tank 24 or wastewater tank 25 from the base 2, pressure needs to be applied to the water tank 24 or wastewater tank 25 again in the negative fourth direction, and the first connecting component and the second connecting component will separate, allowing the water tank 24 to be separated from the base 2.

[0045] For ease of description, this embodiment takes one side of the water storage tank 24 as an example. The wastewater tank 25 has the same structure as the water storage tank 24, and will not be described again in this embodiment.

[0046] like Figure 20 , Figure 21 , Figure 22 As shown, the first connecting assembly includes an insertion block 2711, which is exposed on the side wall of the water tank 24. The second connecting assembly includes a seat 2721, the interior of which is provided with a groove 2722. The axis of the groove 2722 is parallel to the fourth direction. A slidable second piston 2723 and a second elastic member 2724 are disposed within the groove 2722. The second elastic member 2724 is used to move the second piston 2723 toward the seventh end. It is preferably a compression spring, but rubber rings, metal springs, or other elastic components with a reset function can also be used. When the water tank 24 is gradually installed onto the water tank fixing member 26 along the fourth direction under external force, the insertion block 2711 follows the water tank 24 and inserts into the groove 2722, applying a compressive force to the second piston 2723. The second piston 2723 overcomes the elastic force of the second elastic member 2724 and moves toward the eighth end. When the water tank 24 is not subjected to external force, the elastic force of the second elastic member 2724 will squeeze the second piston 2723, and the second piston 2723 will move towards the seventh end to push the water tank 24 towards the seventh end, and the water tank 24 will separate from the water tank fixing member 26.

[0047] like Figure 20 , Figure 21 , Figure 22 As shown, in order to fix the water tank to the water tank fixing member 26, the side of the insert portion 2711 is also provided with a first guide portion 2712 and a second guide portion 2713. Both the first guide portion 2712 and the second guide portion 2713 protrude from the insert portion 2711, and are staggered to form a bent guide groove 2714. The second connecting assembly has a latch 2725 that cooperates with the guide groove 2714. In this embodiment, the latch 2725 is specifically a stainless steel wire capable of slight elastic deformation. The latch 2725 is fixedly connected to the water tank fixing member 26, and extends along the fourth direction. A bent guide hook 2726 is provided near the seventh end of the latch 2725. The bending direction of the guide hook 2726 intersects with the plane containing the guide groove 2714, preferably perpendicular to each other. The design maximizes the engagement surface between the guide hook 2726 and the guide groove 2714, improving engagement stability and preventing separation during use. When the water tank 24 and the water tank fixing member 26 are connected, the guide hook 2726 can slide in the guide groove 2714. Under the action of the second elastic member 2724, the guide groove 2714 tends to move towards the seventh end relative to the guide hook 2726. Therefore, by shaping the inside of the guide groove 2714, the guide hook 2726 can be used to lock the water tank.

[0048] like Figure 22As shown, the guide groove 2714 includes: a first guide slope 27121, disposed on the first guide portion 2712. The first guide slope 27121 extends towards the seventh end and also towards the ninth end. The first guide slope 27121 forms a flared structure at the entrance of the guide groove 2714, allowing the guide hook 2726 to smoothly enter the guide groove 2714. A first abutment groove 27131, disposed on the second guide portion 2713, has its opening facing the eighth end. When the guide hook 2726 enters the guide groove 2714 and moves towards the seventh end relative to the insertion block portion 2711, the guide hook 2726 can engage in the first abutment groove 27131. The function of the first abutment groove 27131 is to limit the maximum movement distance of the guide hook 2726. The second abutment groove 27122 is formed on the first guide portion 2712. The opening of the second abutment groove 27122 faces the seventh end, and in the fifth direction, the second abutment groove 27122 partially overlaps with the first abutment groove 27131, so that when the guide hook 2726 leaves the first abutment groove 27131, it can smoothly enter the second abutment groove 27122. When the guide hook 2726 is engaged in the second abutment groove 27122, the tension of the guide hook 2726 itself counteracts the elastic force of the second elastic member 2724 on the insertion block portion 2711, so that the water tank 24 can be stably installed on the water tank fixing member 26. A second guide slope 27123 is disposed on the first guide portion 2712. The second guide slope 27123 extends towards both the seventh and ninth ends. The second guide slope 27123 is used to facilitate the guide hook 2726's smooth entry into the second abutment groove 27122 when it leaves the first abutment groove 27131. The second guide slope 27123 is a part of the second abutment groove 27122. A third guide slope 27132 is disposed on the second guide portion 2713. The third guide slope 27132 extends towards both the seventh and tenth ends. In the fifth direction, the third guide slope 27132 partially overlaps with the second abutment groove 27122. When the guide hook 2726 disengages from the second abutment groove 27122, it can move towards the tenth end under the guidance of the third guide slope 27132.

[0049] like Figure 22As shown, it also includes: a first check valve 2715 disposed in the guide groove 2714. The first check valve 2715 includes: a first lifting surface 27151 and a first check valve 27152. The first lifting surface 27151 is used to lift the guide hook 2726 upward from the side of the insertion block 2711. The first check valve 27152 spans both sides of the guide groove 2714 and is perpendicular to the side of the insertion block 2711 to prevent the guide hook 2726 from crossing the first check valve 27152 and moving in the opposite direction. The first check valve 27152 is also located on the same plane as the second guide ramp 27123 so that the guide hook 2726 blocked by the first check valve 27152 can smoothly enter the second abutment groove 27122. A second check valve 2716 is disposed within the guide groove 2714. The second check valve 2716 includes a second lifting surface 27161 and a second check valve 27162. The second lifting surface 27161 is used to lift the guide hook 2726, which has disengaged from the first abutment groove 27131, upward from the side of the insert portion 2711. The second check valve 27162 is used to prevent the guide hook 2726 from moving back into the first abutment groove 27131. The second check valve 27162 is also located on the same plane as the third guide ramp 27132. When the guide hook 2726 disengages from the second abutment groove 27122, the guide hook 2726 can move towards the tenth end under the combined action of the second check valve 27162 and the third guide ramp 27132. The third check valve 2717 is disposed in the guide groove 2714. The third check valve 2717 includes a third lifting surface 27171 and a third check valve 27172. The third check valve 27172 and the side wall of the first guide part 2712 are located on the same plane. When the guide hook 2726 disengages from the second abutment groove 27122, it moves towards the tenth end under the action of the second check valve 27162 and the third guide inclined surface 27132. After passing the third lifting surface 27171, it will be blocked by the third check valve 27172 and the side wall of the first guide part 2712, so that the guide hook 2726 moves towards the tenth end while moving towards the eighth end, and then disengages from the guide groove 2714.

[0050] like Figure 20 As shown, in some embodiments, to improve the stability of the connection, in the sixth direction, a set of first guide portions 2712 and second guide portions 2713 are provided on each of the opposite sides of the insert portion 2711 (each set includes one first guide portion 2712 and one second guide portion 2713). Similarly, the water tank fixing member 26 is provided with two latches 2725, which are bent to form two opposing guide hooks 2726, respectively cooperating with two guide grooves 2714. Furthermore, the two latches 2725 are distributed along the fifth direction, and the two guide grooves 2714 are mirror-distributed so that the two guide grooves 2714 can be evenly stressed.

[0051] like Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, the base 2 is also equipped with two quick-stop structures 28. Both the water storage tank 24 and the wastewater tank 25 are connected to the water passages within the base 2 via these quick-stop structures 28. On one side of the water storage tank 24, the quick-stop structure 28 mainly comprises two ends. One end is located on the water tank fixing member 26 for stable connection with the internal pipelines of the base 2, and the other end is located on the water storage tank 24. The quick-stop structure 28 can cooperate with the pressing and positioning structure. When the water storage tank 24 and the water tank fixing member 26 are fixed together, the two ends of the quick-stop structure 28 connect to form a passage, allowing the water passages within the base 2 to draw cleaning fluid from the water storage tank 24 through the quick-stop structure 28. When the water storage tank 24 is separated from the water tank fixing member 26, the quick-stop structure 28 closes promptly, preventing leakage of the cleaning fluid from the water storage tank 24. Similarly, on one side of the wastewater tank 25, the quick-stop structure 28 also includes two ends. When the wastewater tank 25 is fixed to the water tank fixing member 26, the two ends of the quick-stop structure 28 are connected to form a passage. The water passage in the base 2 can release waste liquid into the wastewater tank 25 for temporary storage through the quick-stop structure 28. When the wastewater tank 25 is separated from the water tank fixing member 26, the quick-stop structure 28 can close in time to prevent the waste liquid in the wastewater tank 25 from leaking.

[0052] The quick-stop structure 28 includes a connector 281 and a connecting tube 282. The connector 281 is tubular, with one end connected to the water tank fixing member 26 and communicating with the water passage inside the base 2. The other end of the connector 281 extends along the positive direction of the fourth direction. The water tank 24 is provided with an outlet 241. The connecting tube 282 is fixedly connected to the water tank 24 and is positioned on the outlet 241 to block it. When the water tank moves along the negative direction of the fourth direction, the connector 281 can be inserted into the connecting tube 282 of the water tank 24. When the connector 281 is inserted into the connecting tube 282, the connecting tube 282 changes from a closed state to an open state, and the liquid in the water tank 24 can sequentially enter the hand handle 1 through the connecting tube 282 and the connector 281.

[0053] A first through hole 2821 is provided on the side wall of the connecting cylinder 282, and a second through hole 2822 is provided on the side of the connecting cylinder 282 near the seventh end. A first elastic element 2823 and a first piston 2824 are disposed inside the connecting cylinder 282. The first piston 2824 can slide between a blocking position and a connecting position along the axial direction of the connecting cylinder 282. The first elastic element 2823 is disposed between the first piston 2824 and the inner side wall of the connecting cylinder 282, so that the first piston 2824 has a tendency to move towards the blocking position or can be kept in the blocking position. A drainage portion 2811 is provided on the side wall of the plug-in 281, located near the eighth end. The drainage portion 2811 is used to allow liquid from the water storage tank 24 to enter the plug-in 281, preventing the end of the plug-in 281 from abutting against the first piston 2824 and sealing it. When the water tank 24 moves in the negative direction of the fourth direction, the free end of the connector 281 will be inserted into the interior of the connecting cylinder 282 through the second through hole 2822. The first piston 2824 located in the connecting cylinder 282 is pushed and repelled by the connector 281, and can overcome the elastic force of the first elastic member 2823 to move from the blocked position to the connected position. When the water tank 24 is fully installed, the drain part 2811 on the connector 281 is completely located inside the connecting cylinder 282, preventing the cleaning fluid from flowing out of the drain part 2811. The first piston 2824 is pushed to the eighth end and no longer blocks the second through hole 2822. The liquid in the water tank 24 can enter the connector 281 through the first through hole 2821 and the drain part 2811.

[0054] like Figure 19 As shown, in some embodiments, in order to improve the sealing effect, a sealing sleeve 2825 is provided on the second through hole 2822 of the connecting cylinder 282. The sealing sleeve 2825 is annular. When the plug 281 is inserted into the inner ring of the sealing sleeve 2825, it is squeezed against the sealing sleeve 2825 to form a seal.

[0055] like Figure 17 , Figure 18As shown, in some embodiments, the diameter of the first piston 2824 is equal to the inner diameter of the connecting cylinder 282 to achieve secondary sealing. Regardless of whether the first piston 2824 is pressed on the second through hole 2822, there is no gap between the first piston 2824 and the inner wall of the connecting cylinder 282, forming a sealed structure. When the first piston 2824 moves towards the eighth end under the pushing force of the connector 281, the cleaning fluid can only enter the connector 281 through the first through hole 2821 and the drainage part 2811 if the first piston 2824 is closer to the eighth end than the first through hole 2821. Otherwise, the first through hole 2821 will be blocked by the first piston 2824 and cannot enter the connector 281. Conversely, when the first piston 2824 is in the blocking position, the first piston 2824 is closer to the seventh end than the first through hole 2821 to block the conduction between the first through hole 2821 and the second through hole 2822.

[0056] like Figure 16 As shown, in some embodiments, the drainage portion 2811 is specifically a drainage hole or drainage groove. The first elastic element 2823 is preferably a spring, but it can also be other components that can provide elastic force, such as a rubber ring, a rubber band, or a magnetic component that can provide repulsive force. The first elastic element 2823 is arranged along the axis of the connecting cylinder 282, and can continuously apply an elastic force along the axial direction to the first piston 2824.

[0057] Similarly, on one side of the wastewater tank 25, an inlet is provided on the wastewater tank 25; the connecting tube 282 of the quick-stopping structure 28 is set on the inlet to block the inlet, and a plug 281 corresponding to the connecting tube 282 is provided at the corresponding position of the water tank fixing part 26. When the wastewater tank 25 is installed on the water tank fixing part 26, the plug 281 is inserted into the connecting tube 282, so that the wastewater tank 25 and the water passage in the base 2 are interconnected.

[0058] like Figure 15 , Figure 16 , Figure 17 , Figure 18As shown, in some embodiments, to improve the integration of the device and the connection stability between the water storage tank 24 and the water tank fixing member 26, in this embodiment, the quick-stop structure 28 and the pressing positioning structure are combined to form a whole. On one side of the water tank fixing member 26, the plug-in member 281 is disposed inside the slide groove 2722, the second elastic member 2724 is sleeved on the plug-in member 281, and the second piston 2723 is also sleeved on the plug-in member 281 and can reciprocate along the plug-in member 281. On one side of the water storage tank 24, a notch 244 is provided on the water storage tank 24. The water outlet 241 of the water storage tank 24 is located inside the notch 244. The insert block 2711 is located inside the notch 244, and the insert block 2711 is provided with a through hole 2718. The through hole 2718 communicates with the water outlet 241. The connector 281 can pass through the through hole 2718 and the water outlet 241 in sequence and enter the connecting cylinder 282, realizing the interconnection of the water passage between the water storage tank 24 and the base 2. When the water storage tank 24 is connected to the water tank fixing member 26, the insert block 2711 and the connector 281 intersect each other. The insert block 2711 enters the slide groove 2722 to push the second piston 2723 to move. The connector 281 passes through the through hole 2718 and the water outlet 241 to enter the connecting cylinder 282 to push the first piston 2824 to move.

[0059] like Figure 21 As shown, the water storage tank 24 is also provided with a filling port 242, which is equipped with a removable sealing cap 243. The shape of the sealing cap 243 is adapted to the filling port 242, and the sealing cap 243 is made of soft material to seal the filling port 242. Liquid in the water storage tank 24 can be poured in through the filling port 242. The connector 281 serves as the liquid output end, and the filling port 242 serves as the liquid input end of the water storage tank 24, to distinguish the usage environment. Similarly, the wastewater tank 25 is also provided with a drain outlet. When the waste liquid in the wastewater tank 25 reaches the critical value, the waste liquid in the wastewater tank 25 can be poured out through the drain outlet.

[0060] In summary, the disassembly and assembly process of the water tank 24 in this embodiment is simple and quick. The plug 281 of the quick-stop structure 28 is connected to the connecting cylinder 282, which has high airtightness and is not prone to leakage. It can also quickly replace the water tank 24 to achieve rapid liquid replenishment. The disassembly and assembly of the water tank 24 by pressing improves the ease of operation and provides an efficient liquid replacement method.
