Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a water tank and a cleaning device having a water tank. Background Technology

[0002] Currently, household cleaning devices with mopping functions are gaining market acceptance and promotion due to their ability to absorb dust and perform wet mopping. These devices typically have a water tank, with a manual switch controlling the water flow. However, because the switch is manual, users often forget to turn it off, resulting in water leaking from the tank and leaving the mop wet, negatively impacting the user experience. Another design solution addresses this by using a ball bearing at the tank's vent to control the water flow. However, this ball bearing's movement is limited by the device's state. When the device is constantly oscillating, the ball bearing continues to roll due to inertia, keeping the tank constantly dispensing water. This prevents the tank from flexibly controlling the water flow, leading to the floor becoming increasingly wet after mopping. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a water tank that can control the water supply or shut off according to the actual situation when in working state, and can automatically shut off the water when not in working state.

[0004] To achieve the above objectives, the technical solution of the present invention includes: a water tank, comprising a water tank body, wherein a water outlet is provided at the bottom of the water tank body, characterized in that it includes a control component, and a receiving groove for accommodating the control component is provided on the water tank body, wherein a vent hole and a limiting groove are provided in the receiving groove, and the vent hole is a through hole opened at the bottom of the limiting groove; the control component includes a rolling element and a push switch, wherein the rolling element is movably disposed in the limiting groove, and the push switch selectively presses and fixes the rolling element; when the rolling element moves under inertia and opens the vent hole, the water outlet opens; when the rolling element stops on the vent hole and blocks the vent hole, the water outlet closes.

[0005] This invention provides a water tank that controls the vent hole and thus the water outlet by employing a control assembly with a dual control structure of a rolling element and a push-button switch. A rolling element and a push-button switch are positioned above the vent hole. The rolling element, driven by inertia, moves freely across the vent hole, thus blocking or opening it, thereby closing or opening the water outlet. The push-button switch selectively presses and fixes the rolling element, allowing it to move freely when needed and be fixed when not in use. This achieves flexible control of the water outlet, preventing the problem of continuous water flow from the tank if it's left open and avoiding the situation where the floor becomes increasingly wet during cleaning due to a lack of automatic water control.

[0006] Preferably, the push switch presses the rolling element under external force, causing the rolling element to stop on the vent hole. By pressing the switch to stop the rolling element on the vent hole, free control of the water outlet is achieved, avoiding the situation where moving the water tank would cause the rolling element to leave when water is not needed, thus preventing uncontrolled water discharge from the water outlet.

[0007] Preferably, the push switch includes a pressing element and an elastic fixing element. The pressing element includes a pressing cover and a supporting element. The two ends of the pressing cover are inclined upwards, and the supporting element extends downwards on the inner wall of the pressing cover. The supporting element abuts against the elastic fixing element and can slide relative to it. The pressing cover covers the limiting groove and forms an accommodating space, in which the rolling element is located. This further optimizes the structure of the push switch. The combination of the pressing element with its two ends inclined upwards and the elastic fixing element on the upper surface achieves the effect of a rocker switch. The elastic fixing element facilitates the rocker pressing action while also fixing the pressing cover, preventing the pressing cover from springing back, thus achieving the effect of fixing the rolling element with a single press.

[0008] Preferably, the support member has support plate assemblies on both sides, and each support plate assembly has an upwardly inclined surface; the surface of the elastic fixing member that abuts against the support member is an inclined surface, which matches the inclined surface of the support plate assembly. This further optimizes the structure of the support member, facilitating the sliding of the support member on the elastic fixing member and preventing the support member from rebounding after abutment.

[0009] Preferably, the receiving groove includes a high groove and a low groove, the low groove for accommodating the elastic fixing member, and the high groove for accommodating the pressing member, with the vent and the rolling member located in the high groove. This further optimizes the structure of the receiving groove, facilitating the installation of the control components through the arrangement of the high and low grooves, and also promoting the coordinated operation between the vent, the rolling member, and the pressing switch.

[0010] Preferably, the inner surface of the press cover is provided with a positioning structure, which is used to confine the rolling element to the vent hole. This further optimizes the structure of the press element, making the contact surface between the press element and the rolling element more reasonable, and facilitating the fixed positioning of the rolling element above the vent hole.

[0011] Preferably, the positioning structure has an outwardly extending inclined guide block. This is a further optimization of the above solution. The inclined guide block facilitates the guidance of the rolling element, allowing it to move around the vicinity of the vent hole during movement and to be guided more quickly to block the vent hole when it needs to stop.

[0012] Preferably, the limiting groove is further provided with a guide member with a concave surface. The guide member has a vent hole that communicates with the vent hole. The vent hole is located at the lowest point of the guide member, and the rolling member moves on the guide member. This is a further optimization of the moving structure of the rolling member, which facilitates guiding the rolling member above the vent hole to block the vent hole when not in operation, thus realizing the automatic water shut-off function.

[0013] Preferably, the vent hole and the air vent are located on the same axis, and the diameter of the vent hole is less than or equal to the diameter of the air vent. This is a further optimization of the above solution, enabling communication between the inside and outside of the water tank through the vent hole and the air vent, which facilitates the effective sealing of the air vent by the rolling element.

[0014] Another objective of this invention is to provide a cleaning device with a water tank, which can control the water supply or shut off according to actual conditions when the water tank is in operation, and can automatically shut off the water when not in operation, thus avoiding the impact on the user experience of the cleaning device due to the inflexible control of the water tank.

[0015] To achieve the above objectives, the technical solution of the present invention includes: a cleaning device with a water tank, comprising the water tank described in any of the above-mentioned embodiments, wherein the water tank is provided with a water inlet and a sealing plug is provided at the water inlet. By providing a water tank with flexibly controllable water output on the cleaning device, the water output from the water tank can be flexibly controlled in wet mopping mode, avoiding the problem of the floor becoming wetter the longer the mopping time, caused by continuous water output from the water tank.

[0026] A water tank according to the present invention is described in conjunction with the accompanying drawings.

[0027] like Figure 1 In the illustrated embodiment, the system includes a water tank body 1, with a water outlet (not shown) at the bottom. The water tank body 1 also has a receiving groove 11 that houses the control component 2. Figure 2 As shown, the receiving groove 11 is provided with a vent 111 and a limiting groove 112, with the vent 111 located at the bottom of the limiting groove 112; the control component 2 includes a rolling element 21 and a push switch 22, the push switch 22 including a pressing element 221 and an elastic fixing element 222; combined with Figure 3 and Figure 4 As shown, the rolling element 21 is movably disposed within the limiting groove 112. The pressing switch 22 selectively presses and fixes the rolling element 21. When the pressing switch 22 is pressed downwards, it fixes and fixes the rolling element 21, causing it to stop moving. When the pressing switch 22 is released, it separates from the rolling element 21, allowing the rolling element to move freely. Figure 3 As shown, the rolling element 21 is stationary on the vent 111. Pressing the switch 22 applies pressure to the rolling element 21, pressing and fixing it in place. The rolling element 21 stops moving, isolating the air inside and outside the water tank, and the water outlet is closed, preventing water from flowing out. Figure 4As shown, when the push switch 22 does not press the rolling element 21, the rolling element 21 moves within the limiting groove 112 and moves away from the vent hole 111. The vent hole 111 connects the air inside and outside the box, causing the water outlet to open and water to flow out.

[0028] Combination Figure 2 and Figure 3 In the illustrated embodiment, the push switch 22 includes a pressing member 221 and an elastic fixing member 222. The pressing member 221 includes a pressing cover 2211 and a supporting member 2212. The two ends of the pressing cover 2211 are respectively inclined upward, and the inner wall of the pressing cover 2211 extends downward to form the supporting member 2212. The supporting member 2212 abuts against the elastic fixing member 222 and slides relative to the elastic fixing member 222. Figure 3 and Figure 4 As shown, this structure causes the other end of the press cover 2211 to be tilted upwards when an external force is applied to one end, while the support member 2212 is biased towards the tilted end and abuts against the elastic fixing member 222, thereby fixing the position and preventing the press cover 2211 from rebounding. In this embodiment, the press cover 2211 covers the limiting groove 112 and forms an accommodating space, and the rolling member 21 moves within the accommodating space formed by the press cover 2211 and the limiting groove 112.

[0029] like Figure 4 and Figure 5 In the embodiment shown, the receiving groove 11 includes a high groove 113 and a low groove 114. The elastic fixing member 222 is housed in the low groove 114, and the pressing member 221 is housed in the high groove 113. The vent hole 111 and the rolling member 21 are disposed in the high groove 113.

[0030] Combination Figure 4 and Figure 6 In the illustrated embodiment, the inner surface of the press cover 2211 is also provided with a positioning structure 22111. In this embodiment, the positioning structure 22111 is an upwardly protruding arc-shaped surface. The highest point of the arc-shaped surface is located on the same axis as the vent hole 111. In other embodiments, the positioning structure 22111 is not limited to an arc-shaped surface and can be other shapes. At the same time, inclined guide blocks 22112 extend outward from the periphery of the positioning structure 22111. Both the positioning structure 22111 and the inclined guide blocks 22112 are guide structures provided to cooperate with the rolling element 21. The number of inclined guide blocks 22112 is not limited. The purpose is to facilitate the guidance of the rolling element so that the rolling element moves around the vicinity of the vent hole 111 when it is in motion, and can be guided to the vent hole 111 more quickly and block the vent hole when it needs to stop.

[0031] Combination Figure 3 and Figure 6In the illustrated embodiment, support plate assemblies 2213 are respectively provided on both sides of the support member 2212. The support plate assembly 2213 has an upwardly inclined slope 22131. The surface of the elastic fixing member 222 that abuts against the support member 2212 is an inclined surface 2221, which matches the slope 22131 of the support plate assembly 2213. This structure facilitates smoother sliding of the support member when the push switch is pressed. In addition, the cooperation of the two matching inclined surfaces further realizes the abutment and fixation between the support member 2212 and the elastic fixing member 222, preventing the push member from rebounding and reducing the fixing effect on the rolling member 21.

[0032] Combination Figure 2 , Figure 3 and Figure 4 In the embodiment shown, the limiting groove 112 is also provided with a guide 115 with a concave surface. The guide 115 is provided with a vent hole 1151 connected to the vent hole 111 on the same axis as the vent hole 111. The vent hole 1151 is located at the lowest point of the guide 115. The rolling member 21 moves on the guide 115. In order to ensure the airtightness between the vent hole 1151 and the vent hole 111, and to facilitate the sealing of the vent hole 111 by the rolling member 21 when sealing the vent hole 1151, the diameter of the vent hole 1151 is set to be less than or equal to the diameter of the vent hole 111.

[0033] In the above embodiments, the rolling element can be a sphere, such as a solid silicone sphere or a metal sphere. To enable the rolling element to better seal the vent when stationary and to better move away from the vent when in motion, the rolling element can also be a hollow sphere with a smaller solid sphere or a filling material such as sand or water inside. The solid sphere or the filling material moves inside the hollow sphere. When the water tank is stationary, due to gravity, the filling material inside will be positioned lower than the hollow sphere, making the center of gravity of the rolling element lower and more conducive to sealing the vent. When the water tank moves, the rolling element moves, i.e., the hollow sphere and the filling material move separately. The center of gravity of the rolling element is irregular during the movement, which in turn causes the rolling element to rotate irregularly, allowing it to better deviate from the vent and improving the continuity of water output from the water tank.

[0034] An embodiment of a cleaning device with a water tank according to the present invention.

[0035] Combination Figures 1 to 7In the illustrated embodiment, the water tank of the above embodiment is provided with a water inlet 12 on the water tank body 1 and a sealing plug 13 on the water inlet 12. After water is added to the water tank through the water inlet 12, the sealing plug 13 is closed, so that the interior of the water tank is connected to the outside through the vent 111. The water outlet of the water tank is controlled by controlling the vent 111. The vent 111 is controlled by the control component 2 to realize the function of automatically closing the water tank in the static state; and to flexibly control the water supply or stop the water outlet of the water tank in the non-static state.
