Technical Field

The utility model relates to the technical field of cleaning and disinfection, in particular to a box assembly, a disinfection module and a floor washing machine.

Background

With the improvement of life quality of people and the increasing importance of sanitation and hygiene of various aspects of families, the floor washing machine becomes a common cleaning tool, and the function of electrolyzing water becomes the standard of the floor washing machine gradually. The floor scrubber can generate electrolysis action on the liquid through the electrolysis device to generate sterilizable liquid and is used for cleaning and sweeping. For example, the scrubber may generate hypochlorous acid and reactive oxygen species with a strong oxidizing property by electrolysis of tap water to assist in sterilizing the floor. The electrolytic preparation of the liquid requires that the liquid is introduced into the storage chamber and then electrolyzed. The electrolysis efficiency of the low-conductivity liquid or the pure water is low, so that the components of the ion slow-release agent can be dissolved before the electrolysis of the liquid to increase the conductivity of the liquid, thereby improving the electrolysis efficiency of the liquid.

In the related art, the design of an electrolytic structure for the electrolytic liquid is complex, and the liquid and the ion sustained release agent are dissolved by soaking or arranging a permeable membrane between the liquid and the ion sustained release agent. When the electrolysis device is idle for a long time and a sterilizable liquid is needed to be prepared immediately, the liquid is needed to be injected into the electrolysis device again, and the ion sustained release agent is waited for to generate a dissolution effect. Therefore, there is a need for a case structure capable of enhancing the efficiency of water electrolysis.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The floor scrubber can generate electrolysis action on the liquid through the electrolysis device to generate sterilizable liquid and is used for cleaning and sweeping. For example, the scrubber may generate hypochlorous acid and reactive oxygen species with a strong oxidizing property by electrolysis of tap water to assist in sterilizing the floor. The electrolytic preparation of the liquid requires that the liquid is introduced into the storage chamber and then electrolyzed. The electrolysis efficiency of the low-conductivity liquid or the pure water is low, so that the components of the ion slow-release agent can be dissolved before the electrolysis of the liquid to increase the conductivity of the liquid, thereby improving the electrolysis efficiency of the liquid.

In the related art, the design of an electrolytic structure for the electrolytic liquid is complex, and the liquid and the ion sustained release agent are dissolved by soaking or arranging a permeable membrane between the liquid and the ion sustained release agent. When the electrolysis device is idle for a long time and a sterilizable liquid is needed to be prepared immediately, the liquid is needed to be injected into the electrolysis device again, and the ion sustained release agent is waited for to generate a dissolution effect. Specifically, in an existing electrolysis device, liquid undergoes an electrolysis reaction in a cavity, and an ion sustained-release agent is arranged in the cavity, so that the conductivity of the liquid can be improved and the electrolysis efficiency can be increased by a dissolution reaction generated by soaking the ion sustained-release agent in the liquid. However, the dissolution process of the static ion sustained release agent is slower, the requirements of users on improving the conductivity and increasing the electrolysis efficiency cannot be met, the ion sustained release agent is often concentrated on one side in the cavity of the electrolysis device, and when more liquid is added into the cavity, the ion sustained release agent cannot rapidly react with all the liquid in a dissolution way, the dissolution uniformity is poor, and the electrolysis efficiency is not improved.

In view of this, referring to fig. 1-15, an embodiment of a first aspect of the present utility model provides a tank assembly 100 for a disinfection module 200, the tank assembly 100 comprising a first housing 110 and a second housing.

Referring to fig. 1-3, the first housing 110 defines a first cavity 111 for storing a liquid. The first housing 110 has a first opening 112 communicating with the first cavity 111. It is understood that the inner circumferential wall of the first housing 110 may be used to define the first receiving chamber 111, and the first housing 110 has the first opening 112 to enable the first receiving chamber 111 to communicate with the outside of the first housing 110. In some embodiments, the first opening 112 may be used to introduce a liquid to be electrolyzed into the first volume 111; in addition, the first opening 112 may be used to introduce a solute that participates in the liquid electrolysis reaction or a solute that can enhance the liquid conductivity into the first chamber 111.

Referring to fig. 1-3, the second housing is disposed in the first cavity 111 and connected to the first housing 110. The second housing defines a second volume 121 for storing solute. It is understood that the second housing is disposed within the first chamber 111 and is capable of storing a solute, and thus the first chamber 111 is also considered to be capable of storing a solute. Furthermore, in some embodiments, the second volume 121 may also be used to store a liquid. The solute is at least partially soluble in the liquid and increases the conductivity of the liquid. It is understood that the electric conductivity of the liquid (solution) after dissolution reaction can be enhanced due to the chemical composition of the solute while the solute is dissolved in the liquid. The solute may have different compositions depending on the type of liquid and the electrolysis requirements. Illustratively, in some embodiments, the solute may comprise one of sodium chloride or sodium nitrate or sodium sulfate, or the solute may also be composed of a variety of inorganic salts and organic macromolecules.

The second housing has a second opening 122 communicating with the second cavity 121. It is understood that the second opening 122 may be used to introduce a solute or liquid into the second chamber 121. In addition, the second opening 122 faces the first opening 112. In the embodiment where the second opening 122 coincides with or is located on the same plane as the first opening 112, the second opening 122 may be considered to face the first opening 112 as well.

In different embodiments, the first housing 110 and the second housing may have a cylindrical housing, a conical housing, a rectangular housing, or other external shapes; in addition, the cross sections of the first and second chambers 111 and 121 may be cylindrical, conical, rectangular, or the like. For convenience of description, the following description will be given by taking an embodiment in which the first housing 110 and the second housing are cylindrical housings, and the cross section of the first cavity 111 along the axis direction perpendicular to the first opening 112 and the cross section of the second cavity 121 along the axis direction perpendicular to the second opening 122 are circular, and different embodiments may be combined with each other in different technical solutions.

Referring to fig. 1 or 3, the second housing is further provided with a liquid guiding structure 123. In some embodiments, liquid-directing structure 123 may be used to drain liquid or solute from second volume 121. Specifically, in various embodiments, the liquid guiding structure 123 may include a liquid guiding through hole (see fig. 3) for guiding the liquid; and/or, the liquid-directing structure 123 includes a permeable membrane capable of permeating a liquid (see fig. 4). For the placement of the liquid guiding structure 123, in some embodiments, the liquid guiding structure 123 may be disposed at the lower end of the second housing. That is, the liquid guiding structure 123 may be disposed on the bottom surface of the second housing, and at this time, the second opening 122 may be disposed on the side wall surface or the top surface of the second housing, so that the liquid in the second cavity 121 can be conveniently guided out of the second cavity 121 under the action of gravity without driving the liquid to flow additionally. Referring to fig. 5, in other embodiments, the liquid guiding structure 123 may also be disposed on a side wall surface of the second housing. Further, in other embodiments, the second housing may be provided on a top surface of the second housing.

For the above arrangement of the first opening 112 and the second opening 122, since the second housing is disposed in the first cavity 111, referring to fig. 3, in some embodiments, the first opening 112 may coincide with the second opening 122, that is, the first cavity 111 and the second cavity 121 may share one opening; further, referring to fig. 6, in other embodiments, the first opening 112 may be larger than the second opening 122; or the first opening 112 may be smaller than the second opening 122.

Referring to fig. 6-7, in various embodiments, the first opening 112 may be a single opening or a collection of openings; likewise, in various embodiments, the second opening 122 may be a single opening or a collection of openings.

Referring to fig. 3-9, the first opening 112 is at least partially coincident with the second opening 122 in a direction parallel to the axis of the first opening 112 such that liquid introduced into the first cavity 111 from the first opening 112 is at least partially introduced into the second cavity 121 from the second opening 122, and liquid introduced into the second cavity 121 dissolves at least a portion of the solute and is then able to be withdrawn from the second cavity 121 from the liquid guiding structure 123. It will be appreciated that the orthographic projection of the aperture edge of the first opening 112 onto a plane perpendicular to the axial direction of the first opening 112 in a direction parallel to the axial direction of the first opening 112 is a first projection, the orthographic projection of the aperture edge of the second opening 122 onto a plane perpendicular to the axial direction of the second opening 122 is a second projection, and the first projection at least partially coincides with the second projection as viewed in a direction parallel to the axial direction of the first opening 112. Thus, the arrangement of the present embodiment is such that the liquid introduced into the first volume 111 from the first opening 112 is at least partially guided by the second opening 122 to the second volume 121. In various embodiments, the liquid may be introduced through the first opening 112 by manually pouring the liquid, or by feeding the liquid through a liquid feeding device.

Also to facilitate the transfer of liquid, in some embodiments, first opening 112 may be connected to a conduit or a liquid inlet pump device, thereby facilitating the introduction of liquid or solute into first volume 111; the second opening 122 may also be connected with a conduit or a feed pump device.

It is understood that the liquid introduced into the second cavity 121 in the present utility model may be a liquid to be electrolyzed, the liquid may have a low conductivity or a zero conductivity, and the solute in the second cavity 121 may be dissolved in the liquid to improve the conductivity of the liquid in the second cavity 121. Illustratively, in some specific embodiments, the liquid to be electrolyzed may be water (including tap water, pure water, etc.), and the solute may be sodium chloride, accordingly. After the water is introduced into the first chamber 111, at least a portion of the water can enter the second chamber 121, and sodium chloride in the second chamber 121 can at least partially dissolve in the water and form an aqueous sodium chloride solution. Thereafter, the aqueous sodium chloride solution (which may include water not involved in dissolution as well as sodium chloride) can be conducted out of the second volume 121 by the liquid guiding structure 123.

In various embodiments, the liquid may be directly stored in the first cavity 111 and located outside the second cavity 121 after being led out from the second cavity 121, so in some embodiments, an electrolysis device may be further disposed in the first cavity 111 of the tank assembly 100, and the liquid may react with the electrolysis device in the first cavity 111 after being led out from the second cavity 121; or in other embodiments, the electrolysis device may be disposed within the second chamber 121 such that the liquid dissolves the solute and increases conductivity and then can rapidly participate in the electrolysis; or in other embodiments, the fluid may be further directed from the fluid delivery structure to the electrolyzer, and thus the electrolyzer may be disposed outside the first chamber 111 of the housing assembly 100.

To facilitate cleaning, servicing, or removal of tank components, solutes, of the tank assembly 100, referring to fig. 10, in some embodiments, the first housing 110 may be further split into an upper housing and a lower housing. The upper case may be detachably coupled with the lower case, thereby facilitating the disassembly of the case assembly 100 by the user and leaving a certain operation space for the user.

According to a combination of the above embodiments, the tank assembly 100 may be adapted for a user to introduce liquid from the first opening 112 into the first cavity 111 and at least part of the liquid from the second opening 122 into the second cavity 121; the solute in the second cavity 121 can be at least partially dissolved in the liquid and improve the conductivity of the liquid in the second cavity 121, and further, the liquid in the second cavity 121 can be led out of the second cavity 121 through the liquid guiding structure 123 and can be used for electrolysis. Compared with the electrolysis device of the related art, the solution and the ion sustained release agent are soaked or a permeable membrane is arranged between the solution and the ion sustained release agent to generate a dissolution reaction and improve the electrolysis efficiency of the solution, and thanks to the improvement of the solution of the present utility model, the tank assembly 100 of the present utility model can pre-set a solute in the second chamber 121, when a user needs to electrolyze the solution and needs to improve the conductivity of the solution in a short time, the solution to be electrolyzed can be introduced into the first chamber 111 and simultaneously introduced into the second chamber 121, the solution in the second chamber 121 can dissolve at least part of the solute, and then the solution in the second chamber 121 can be led out of the second chamber 121 by the solution guiding mechanism. In addition, due to the influence of the acting force of the externally introduced liquid, the liquid is in a flowing state when being introduced into the second containing cavity 121, and the liquid can be led out of the second containing cavity 121 after the solute is dissolved, the liquid can be quickly and fully contacted with the solute, the dissolution efficiency of the liquid is improved, and the phenomenon of uneven liquid dissolution can be effectively reduced. Therefore, the tank assembly 100 of the present utility model can improve the efficiency of dissolving solute and the uniformity of dissolution, which is beneficial to rapidly improving the conductivity of the liquid.

For the positioning of the first opening 112 and the second opening 122, in order to facilitate the guiding of the liquid to the second cavity 121, see fig. 11, in some embodiments, the second housing 120 may cover the first opening 112 such that the liquid introduced into the first cavity 111 by the first opening 112 is introduced into the second cavity 121 by the second opening 122. The following definition is made herein for "the second housing 120 covers the first opening 112": the orthographic projection of the aperture edge of the first opening 112 on a plane perpendicular to the axial direction of the first opening 112 is a first projection, the orthographic projection of the outer contour of the second housing 120 on a plane perpendicular to the axial direction of the second opening 122 is a second projection, and in this embodiment, the area range of the first projection is located within the area range of the second projection or the area range of the first projection coincides with the area range of the second projection, as viewed in a direction parallel to the axial direction of the first opening 112. It will be appreciated that, due to the arrangement of the second housing 120 covering the first opening 112, all the liquid entering the first cavity 111 from the first opening 112 can flow through the second cavity 121 from the second opening 122, so that the liquid introduced into the first opening can be dissolved into the solute and form the liquid with higher efficiency.

To facilitate removal of the solute, referring to fig. 9, in some embodiments, the solute may be adapted to be removed from or placed into the second cavity 121 by the second opening 122 and to be removed from or placed into the first cavity 111 by the first opening 112. To further increase the conductivity of the liquid, in some embodiments, a portion of the solute may also be disposed outside the first chamber 111 and outside the second chamber 121. In particular, in some embodiments, the second housing may be adapted to be separated from the first housing 110 and capable of being removed from the first opening 112 or placed into the first housing 110, for specific implementations, see below. Or in other embodiments, the second housing may have a lifting mechanism attached thereto that enables the second housing to extend at least partially from within the first cavity 111. Therefore, in the present embodiment, the solute is suitable for being taken out or put in based on the setting of the second opening 122 or the setting of the first opening 112, so that the solute can be conveniently replaced by the user at any time, and the convenience of operation of the user is effectively improved.

For the connection of the first housing 110 and the second housing. Referring to fig. 3-8, in some embodiments, the second housing may be fixedly coupled to the first housing 110. Alternatively, referring to fig. 9, in other embodiments, the second housing may be removably coupled to the first housing 110, and the second housing is adapted to be removed from or placed into the first housing 110 through the first opening 112. Specifically, for the purpose of the detachable connection, referring to fig. 9, in some embodiments, the first housing 110 may have a groove, where a side of the groove away from the second opening 122 can define the first opening 112, and a side of the groove close to the second opening 122 is used for connecting the second housing, and a side wall surface of the second housing defining the second opening 122 may be clamped with the groove, or the second housing may be supported and connected by an end surface of the first housing 110, or an upper side wall surface of the groove. In the present embodiment, the second housing can be taken out or assembled from the first housing 110 alone, and thus the arrangement can facilitate cleaning, maintenance, and simultaneously can facilitate the removal or placement of the solute from the second opening 122 into the second chamber 121, and the removal or placement of the solute from the first opening 112 into the first chamber 111.

Referring to fig. 3, in some embodiments, the aperture edge of the first opening 112 may be connected with a peripheral wall plate 113 extending into the first cavity 111. Based on the above arrangement, the end of the peripheral wall plate 113 facing away from the first opening 112 may connect the orifice edge of the second opening 122. It will be appreciated that in this embodiment, liquid introduced by the first opening 112 can flow from the first opening 112 to the Zhou Biban, 113, and liquid flowing through Zhou Biban can flow to the second opening 122 and into the second cavity 121. Thus, the arrangement enables Zhou Biban 113 to drain the liquid, and can improve the flow efficiency of the liquid. In various embodiments, zhou Biban 113 can be an annular peripheral wall disposed about the axis of first opening 112, or a rectangular peripheral wall, or a peripheral wall extending in other shapes.

Referring to fig. 4, in an embodiment in which Zhou Biban 113 is an annular peripheral wall, the diameter of the annular peripheral wall may gradually decrease in a direction from the first opening 112 toward the second opening 122. That is, in the present embodiment, the annular peripheral wall is an annular tapered surface, and facilitates guiding the liquid to the second opening 122. Further, in some embodiments, zhou Biban, the orifice edge of first opening 112, and the orifice edge of second opening 122 may collectively define a liquid inlet plenum. The liquid inlet cavity can be used for storing liquid, or buffering the liquid, or is used for being installed and connected with the second shell. In other embodiments, the diameter of the annular peripheral wall may gradually increase in a direction from the first opening 112 toward the second opening 122.

Referring to fig. 1 and 12, in some embodiments, the case assembly 100 may further include a cover. The cover may have a closed state and an open state. Specifically, in some embodiments, in the closed state, the cover is connected to the first housing 110 and covers the first opening 112; in the opened state, the cover is coupled to or separated from the first housing 110, and opens the first opening 112. It will be appreciated that, based on the above-described arrangement of the cover, the cover can close the first opening 112 when the solute is dissolved, or the liquid is electrolyzed, so that the cover is in a closed state, which can reduce the influence of the external environment (including factors such as temperature, air pressure, air, impurities, etc.) on the functions of the tank assembly 100. In addition, the open state of the cover may facilitate a user's access to solute, introduction of liquid, or cleaning or servicing of the tank assembly 100. And the cover body is in after opening the state, the user can directly perceived the solute consumption condition of slowly releasing, and the solute change operation is more convenient.

For embodiments in which the housing assembly 100 further includes a cover, the sealing performance of the cover in the closed state is enhanced. Referring to fig. 12-13, in some embodiments, a side of Zhou Biban facing away from first opening 112 may be provided with an annular end surface 1131 facing first opening 112. Based on this, the cover may include a sealing portion 131, and in the closed state, the sealing portion 131 may extend into Zhou Biban and abut against the annular end face 1131. In order for the seal 131 to be adapted to abut the annular end surface 1131 and have good sealing properties, in some embodiments, the diameter of the annular end surface 1131 may be greater than the diameter of the second opening 122, that is, the annular end surface 1131 may be stepped with respect to the second opening 122 such that the annular end surface 1131 may facilitate abutment and positioning of the seal 131.
