Background

At present, some floor washing machines on the market have the function of electrolyzing water, and the floor washing machine with the function of electrolyzing water has a good sterilizing effect on floors. Specifically, the scrubber comprises an electrolytic water module, and the electrolytic water module is used for generating substances with strong oxidizing property (such as hypochlorous acid, active oxygen and the like) after the clean water for scrubbing is electrolyzed; when the clear water contacts the floor, the strong oxidizing substances mixed in the clear water contact bacteria on the floor, thereby killing the bacteria.

However, some users may inject water having a low chlorine content or pure water into the scrubber, and the conductivity of the water injected into the scrubber may be low, depending on the local water quality of the user, the use habit of the user, and the like. In the case where the conductivity of water of the scrubber is low, the efficiency of electrolysis of water by the electrolyzed water module may be reduced, and a user waits for the electrolysis time of the scrubber to be long.

Fig. 1 illustrates a tank assembly 100 in one embodiment of the present utility model, and fig. 3 illustrates tank assembly 100 from another perspective. Referring to fig. 1, a water tank assembly 100 includes a water tank 101, the water tank 101 including a first case 103, a second case 104, and a top cover 102 detachably connected to each other, the first case 103 being connected to a rear side of the second case 104, and a top end of the first case 103 and a top end of the second case 104 being connected to the top cover 102. Fig. 4 and 5 show the water tank assembly 100 of fig. 1 with the second housing member 104 and the top cover 102 removed, and fig. 6 is a cross-sectional view of the water tank assembly 100 of fig. 5 taken along the section A-A. Referring to fig. 1 and 4, the water tank 101 has a first chamber 109, the first chamber 109 being defined by the first housing member 103, the second housing member 104 and the top cover 102, the first chamber 109 being for containing water to be electrolyzed. The water in the first chamber 109 is not specifically shown, and the water added to the first chamber 109 may be tap water, pure water, or the like.

Referring to fig. 4, an electrolyzed water module 201 is connected to the water tank 101, at least a portion of the electrolyzed water module 201 is disposed in the first chamber 109, and the electrolyzed water module 201 is configured to electrolyze water in the first chamber 109. More specifically, as shown in fig. 6, the electrolyzed water module 201 includes an electrode 203, the electrode 203 is disposed in the first chamber 109 and is capable of contacting water in the first chamber 109, when the electrode 203 is energized, the electrode 203 electrolyzes water, and the electrolyzed water contains a large amount of highly oxidizing substances. The water tank 101 is further provided with a clean water outlet, not shown in the figures, which may be provided at the bottom end of the water tank 101, from which the electrolyzed water may leave the first chamber 109.

As shown in fig. 6, the water tank assembly 100 further includes a solution container 108, the solution container 108 having a second chamber 110 and a solution outlet 112 (the solution outlet 112 is shown in fig. 7). As shown in fig. 7, the second chamber 110 is configured to hold a saline solution 301, and the saline solution 301 may exit the second chamber 110 from the solution outlet 112 and then enter the first chamber 109, and the flow path of the saline solution 301 may be referred to by the dashed arrow in fig. 7.

The term "salt" as used herein refers to a salt in chemical sense, and the term "salt" as used herein refers to a compound formed by combining a metal ion or an ammonium ion with an acid ion. The salt solution 301 is a solution of a salt dissolved in a solvent, which may be an organic solvent or an inorganic solvent, or an organic salt or an inorganic salt. The ion concentration of the salt solution 301 in the second chamber 110 is higher than the ion concentration of the water in the first chamber 109. The ion concentration of the salt solution 301 is the sum of the concentration of anions and cations in the salt solution 301, and the ion concentration of water in the first chamber 109 is the sum of the concentration of anions and cations in water.

The operation of the tank assembly 100 will be briefly described. As shown in fig. 7, in the case where the first chamber 109 contains water and the second chamber 110 contains the salt solution 301, the salt solution 301 may enter the first chamber 109 through the solution outlet 112 and then be mixed with the water in the first chamber 109. The ion concentration of the water increases after the water is mixed with the salt solution 301. Generally, the higher the concentration of ions in a solution, the higher the conductivity of the solution. Accordingly, after the water is mixed with the salt solution 301, the conductivity of the water is also improved, and the electrolysis efficiency of the water electrolysis module 201 in the subsequent electrolysis of the water in the first chamber 109 is improved.

In summary, the water tank assembly 100 of the present utility model increases the ion concentration of water by mixing the salt solution 301 in the solution container 108 with the water in the water tank 101, thereby increasing the electrolysis efficiency of the water tank assembly 100 to water.

In some embodiments, the salt solution 301 is an inorganic salt, which generates more ions after being dissolved in water, and has a higher ion concentration, which is more beneficial to improving the conductivity of water. The inorganic salt selected for the salt solution may include one or more of sodium chloride, sodium nitrate, sodium sulfate. If an organic solvent is used for the salt solution 301, a surfactant commonly used in a cleaning agent may be used as the organic solvent, and a surfactant which is non-toxic to the human body and does not stain the floor may be used. In addition, in the present utility model, since ions of the salt solution 301 may enter into the water of the first chamber 109, even if the water added into the first chamber 109 is pure water, the water in the first chamber 109 may contain a large amount of active material having strong oxidizing property after the electrolysis of the water module 201. For example, sodium chloride is used as the salt, and after chloride ions are mixed into water, the water is electrolyzed to generate chlorate ions.

One means for increasing the efficiency of water electrolysis in the prior art is to provide silver ion balls on the electrodes 203 of the electrolyzed water module 201 to increase the ion concentration and conductivity of water by silver ions released when the silver ion balls are electrolyzed. However, silver ions can affect the lifetime of the coating of the electrode 203. The present utility model can improve the service life of the electrode 203 by improving the electrolysis efficiency of water by using the salt solution 301 in which the salt containing no silver ion and the solvent are mixed without providing the silver ion ball.

Referring to fig. 7, in an embodiment, the water tank assembly 100 further includes a slow release member 111, the slow release member 111 being installed at the solution outlet 112, the slow release member 111 being provided as a porous ceramic body. The porous ceramic body is capable of passing the salt solution 301, the porous ceramic body itself having the pores 113, the salt solution 301 being permeable into the first chamber 109 through the pores 113 of the porous ceramic body. Since the slow release member 111 is provided at the solution outlet 112, the speed of the saline solution 301 entering the first chamber 109 is slow (compared to the case where the slow release member 111 is not provided at the solution outlet 112), the saline solution 301 is not easy to enter the first chamber 109 entirely at a time, the saline solution 301 can be used for a long time, and the user does not need to frequently replenish the saline solution 301 to the second chamber 110. For example, after the water in the first chamber 109 is exhausted, a portion of the saline solution 301 may remain in the solution container 108, and this portion of the saline solution 301 may be used to mix with the water that is next added to the first chamber 109. For ease of explanation of the principle, the aperture 113 in fig. 7 is drawn relatively large. In order to enable the saline solution 301 to be released into the first chamber 109 at a slower rate, the pore size of the pores 113 may be set to the micrometer scale, i.e. the pore size of the pores 113 is less than or equal to 1000 micrometers. In addition, since the porous ceramic body is relatively rigid and has a long service life, a user does not need to frequently repair or replace the slow release member 111 during the use of the water tank assembly 100, which is advantageous in saving the use cost of the water tank assembly 100.

In another embodiment, the slow release member 111 may be provided as a permeable membrane, which also has a hole 113 for allowing the salt solution 301 to pass therethrough, and the permeable membrane may also realize the slow release function of the salt solution 301. The sustained release member 111 may also be provided as an object other than a permeable membrane and a porous ceramic body, as long as the sustained release member 111 has a micrometer-sized pore and the pore 113 is capable of passing the salt solution 301.

In one embodiment, the sustained release member 111 is provided as a porous ceramic body, and the pore size of the pores 113 of the porous ceramic body is smaller than the diameter of water molecules, and the pore size of the pores 113 is also larger than the diameter of ions in the salt solution 301. In this arrangement, ions in the salt solution 301 can still pass through the slow release member 111 and enter the first chamber 109, while the slow release member 111 has a function of blocking water from being transferred from the first chamber 109 into the second chamber 110, water in the first chamber 109 does not enter the second chamber 110 through the slow release member 111, the salt solution 301 in the second chamber 110 is not diluted by water, and is not polluted or deteriorated by impurities of the water in the first chamber 109. Thus, the quality of the saline solution 301 is stable during the long-term use of the water tank assembly 100, and the electrolytic efficiency of the water tank assembly 100 to water is stable.

Of course, in order to block the transfer of water from the first chamber 109 to the second chamber 110, the slow release member 111 may be provided as a permeable membrane having selective permeability, as long as the permeable membrane can block the passage of water and can pass ions in the salt solution 301.

Where a slow release member 111 is provided, the tank assembly 100 can achieve slow release of the saline solution 301 without the need for complex circuitry or valves.

Referring to fig. 6, the solution container 108 is formed in a column shape and extends in a vertical direction, and the bottom end of the solution container 108 is located above the electrolyzed water module 201, as shown in fig. 7, the solution outlet 112 is provided at the bottom end of the solution container 108, and accordingly, the slow release member 111 is also installed at the bottom end of the solution container 108. This has the advantage that even if the sump assembly 100 is inclined with respect to the vertical during use of the scrubber, the saline solution 301 in the second chamber 110 can flow to the solution outlet 112 or the slow release member 111 by its own weight, thereby smoothly entering the first chamber 109.

As shown in fig. 7, the electrolyzed water module 201 is disposed opposite to the slow release member 111 and spaced apart, which is advantageous in that the electrolyzed water module 201 is capable of improving the electrolysis efficiency of water in the first chamber 109. Specifically, the arrangement of the electrolyzed water module 201 spaced from the sustained release member 111 means that the two are not closely adhered to each other, and the salt solution 301 passing through the sustained release member 111 can smoothly enter the first chamber 109. Since the salt solution 301 entering the first chamber 109 through the slow release member 111 is mainly concentrated near the slow release member 111 and the electrolyzed water module 201 is disposed opposite to the slow release member 111, the ion concentration of water around the electrolyzed water module 201 is high, the electrolysis rate of water in this area is high, and the electrolysis efficiency of the electrolyzed water module 201 when electrolyzing water is high.

Referring to FIG. 7, if the distance between the electrolyzed water module 201 and the extended release member 111 is designated as D, then in some embodiments D is 5mm. More specifically, in fig. 7, the distance between the electrolyzed water module 201 and the sustained release member 111 refers to the distance between the top surface of the electrolyzed water module 201 and the bottom surface of the sustained release member 111. During electrolysis of water, some gases (such as oxygen) are generated, which form bubbles in the water. The distance between the electrolyzed water module 201 and the sustained release member 111 is not less than 5mm such that there is a larger spacing between the electrolyzed water module 201 and the sustained release member 111, which is advantageous in reducing the influence of the above-described gas or bubbles on the rate at which the salt solution 301 is transferred through the sustained release member 111 to the first chamber 109. Moreover, when the electrolytic reaction is severe, the gas production amount is large, and if the distance between the electrolytic water module 201 and the slow release member 111 satisfies the above condition, the impact of the gas or the bubbles on the slow release member 111 is small and the risk of damaging the slow release member 111 is small because the distance between the electrolytic water module 201 and the slow release member 111 is not too small. In addition, in order to reduce the influence of gas or bubbles generated by electrolysis on the slow release member 111, the electrode 203 of the electrolyzed water module 201 and the slow release member 111 may be disposed at a spacing in the horizontal direction. For example, referring to fig. 6, electrode 203 is positioned below sustained release member 111 and forward of sustained release member 111, electrode 203 being offset from sustained release member 111.

In one embodiment, at least a portion of the water tank 101 is transparent along the height of the water tank 101, so that a user can conveniently observe the remaining amount of water in the first chamber 109, thereby facilitating the user in determining whether or not water needs to be replenished into the first chamber 109. Similarly, in one embodiment, at least a portion of the solution container 108 is transparent along the height of the solution container 108 so that a user can observe the remaining amount of the saline solution 301 in the second chamber 110, thereby facilitating a user's determination as to whether the saline solution 301 needs to be replenished to the second chamber 110.

Referring to fig. 6, in one embodiment, the solution container 108 is integrally provided in the first chamber 109, which has the advantage that the space occupied by the water tank assembly 100 can be reduced. The solution container 108 and the water tank 101 may be of a split type design or an integral type design. The solution container 108 and the water tank 101 are in a split type design, namely, the solution container 108 and the water tank 101 are respectively two mutually detachable parts; the solution container 108 and the water tank 101 are integrally formed, and the solution container 108 and the water tank 101 are not detachable. In fig. 4 to 7, the solution container 108 and the water tank 101 are integrally designed, so that the solution container 108 and the water tank 101 do not need to be assembled in the process of producing the water tank assembly 100 or the floor scrubber, and the assembly convenience of the water tank assembly 100 and the floor scrubber is high.

In the case where the solution container 108 is provided in the first chamber 109, both the solution container 108 and the water tank 101 may be transparent. This has the advantage that the user can observe the remaining amount of the saline solution 301 in the second chamber 110, and can determine whether the saline solution 301 needs to be replenished into the second chamber 110 without disassembling the water tank assembly 100. More specifically, the solution container 108 and the water tank 101 may be made of transparent glass or transparent plastic.

Further, in the case where the solution container 108 is located in the first chamber 109 and both the solution container 108 and the water tank 101 are transparent, the solution container 108 may be connected to a side wall of the first chamber 109. If the solution container 108 is disposed at the center of the water tank 101 and the solution container 108 is spaced apart from any one of the sidewalls of the first chamber 109, the water of the first chamber 109 may affect the user's view of the remaining amount of the saline solution 301 in the solution container 108 when the level of the water in the water tank 101 is high. While the solution container 108 is connected to the wall surface of the first chamber 109 such that the solution container 108 is closer to the outer side surface of the water tank 101, the user can more easily observe the solution container 108 and the salt solution 301 in the solution container 108.

The water tank 101 and the solution container 108 may be transparent as a whole or may be partially transparent. For example, the lower half of the water tank 101 and the lower half of the solution container 108 are transparent, and if the user fails to see the level of water from the lower half of the water tank 101, then there is no need to replenish the first chamber 109 with water, and if the user fails to see the level of the salt solution 301 from the lower half of the solution container 108, then there is no need to replenish the second chamber 110 with salt solution 301, then there is more salt solution 301 in the solution container 108.

How water is added to the water tank 101 and how the salt solution 301 is added to the solution container 108 are briefly described below. Referring to fig. 2, the water tank 101 is provided with a fresh water inlet 106, the fresh water inlet 106 being located on the top cover 102, the fresh water inlet 106 being in communication with the first chamber 109, and a user can add water to the first chamber 109 through the fresh water inlet 106. Referring to fig. 1 and 2, the water tank assembly 100 further includes a first sealing cover 105, the first sealing cover 105 being connected to the water tank 101, and a user can cover the fresh water inlet 106 with the first sealing cover 105 after the water is replenished, so as to prevent water in the water tank 101 from leaking and prevent impurities such as dust from entering the water tank 101. Referring to fig. 3 and 4, the solution container 108 is provided with a solution inlet 107, the solution inlet 107 being located at an outer surface of the water tank 101, and a user can add the saline solution 301 to the second chamber 110 through the solution inlet 107. The water tank assembly 100 further includes a second sealing cover (not shown) by which a user can cover the solution inlet 107 after the saline solution 301 is replenished, to prevent the saline solution 301 from leaking and to prevent impurities such as dust from entering the solution container 108.

Referring to fig. 2 and 3, a fresh water inlet 106 and a solution inlet 107 may be provided on opposite sides of the tank 101 assembly 100, respectively. In this way, the distance between the fresh water inlet 106 and the solution inlet 107 is relatively long, even if water is added to the fresh water inlet 106 and the saline solution 301 is added to the holding liquid inlet at the same time, the addition of water and the addition of the saline solution 301 do not interfere with each other. Moreover, since the fresh water inlet 106 and the solution inlet 107 are provided on different sides of the assembly 100 of the water tank 101, the user is less likely to confuse the fresh water inlet 106 with the solution inlet 107, and the risk of the user adding the liquid to be added to the wrong place is low. In addition, when the water tank 101 assembly 100 is connected to the body of the scrubber, the fresh water inlet 106 faces the body, the solution inlet 107 faces away from the body, and the solution container 108 is positioned at a position that is easily observed by a user, so that the user can observe the remaining amount of the saline solution 301.

Referring to fig. 6, in some embodiments, the tank 101 assembly 100 further includes a movable member 117 and an elastic member 119, the movable member 117 being slidably coupled to the tank 101 and capable of being lifted and lowered relative to the tank 101. The movable member 117 includes a pressing portion 115 and a locking portion 116 fixed to each other, and the pressing portion 115 is disposed below the locking portion 116. The top end of the elastic member 119 is connected to the pressing portion 115, the bottom end of the elastic member 119 is connected to the first housing member 103 of the water tank 101, and the elastic member 119 is in a compressed state. Referring to fig. 3 together, the pressing portion 115 is exposed outside the water tank 101 so that a user can contact the pressing portion 115, and the locking portion 116 protrudes with respect to the top surface of the water tank 101. More specifically, the first housing member 103 is provided with a relief hole 118, and the pressing portion 115 is provided in the relief hole 118 so as to be exposed to the outside of the water tank 101; the top surface of the top cover 102 serves as the top surface of the water tank 101, and the locking portion 116 penetrates the top surface of the top cover 102.

The pressing portion 115 can be contacted by a user's hand and pressed by the user, and the locking portion 116 can be connected to the body of the floor scrubber. More specifically, the body of the floor washer is provided with a socket (the body and its socket are not shown) at a position corresponding to the locking portion 116, and when the locking portion 116 is inserted into the socket, the water tank 101 assembly 100 and the body of the floor washer are fixed to each other. After the locking portion 116 is disengaged from the insertion hole, the user can detach the water tank 101 assembly 100 from the body.

When a user desires to mount the water tank 101 assembly 100 to the body, the user may press the pressing part 115 to move the movable member 117 downward, thereby reducing the protruding distance of the locking part 116 with respect to the top surface of the water tank 101, so as to put the water tank 101 assembly 100 into the body. After the water tank 101 assembly 100 is put into the body, the user can release the pressing part 115, and the movable member 117 moves upward under the elastic force of the elastic member 119 and is inserted into the insertion hole of the body, thereby achieving the connection between the water tank 101 assembly 100 and the body. When the user desires to detach the water tank 101 assembly 100 from the main body (e.g., desires to detach the water tank 101 assembly 100 and add water to the first chamber 109), the user may press the pressing portion 115 again, move the locking portion 116 downward and out of the insertion hole, and then the user withdraws the water tank 101 assembly 100 from the main body. In the case where the tank 101 assembly 100 is provided with the movable member 117 and the elastic member 119, convenience in assembly and disassembly between the tank 101 assembly 100 and the body is high.

In one embodiment, the outer surface of the water tank 101 is provided with grooves 114 into which the hands of the user can be inserted, and the top walls of the grooves 114 are spaced below the pressing portions 115. The water tank 101 is provided with a groove 114 to facilitate a user's mounting the water tank 101 assembly 100 to the body or removing the water tank 101 assembly 100 from the body. Specifically, when the user presses the pressing portion 115, the user can put the thumb on the pressing portion 115 and press the other fingers such as the index finger and the middle finger against the top wall of the groove 114, so that the user can move the pressing portion 115 downward through a "pinching" action. The top wall of the recess 114 provides a convenient location for the user to push down on the push down portion 115 and the pick-and-place tank 101 assembly 100.

To facilitate user access to the solution inlet 107 and addition of the saline solution 301 to the solution container 108, the solution inlet 107 of the solution container 108 may be disposed on a side or bottom wall of the recess 114, or the solution inlet 107 may be disposed on a wall other than the top wall of the recess 114. In the prior art, a means of placing a salt box in the water tank 101 is also adopted to improve the conductivity of water, and after salt (solid state) in the salt box contacts and dissolves with water, the ion concentration and conductivity of water can be improved. However, the salt box is installed inside the water tank 101, and replacement of the salt box is inconvenient. The solution inlet 107 of the present utility model is provided on the side wall or the bottom wall of the recess 114, and the user does not need to disassemble the water tank 101 to replenish the saline solution 301, which is more convenient for the user to replenish the saline solution 301 to the second chamber 110.

The present utility model also provides a floor scrubber comprising the water tank assembly 100 of any of the above embodiments, wherein the water of the first chamber 109 of the water tank assembly 100 acts as "clean water" for cleaning floors. Because the water tank assembly 100 has higher electrolysis efficiency on water, the time for a user to wait for the scrubber to electrolyze water is shorter, and the scrubber has better use experience.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
