[0060] The utility model provides a fish tank cleaning device 100, such as Figures 1 to 4 As shown, including:

[0061] The housing 10 has a mounting cavity, and a liquid inlet 121 and a liquid outlet 111 are provided on the mounting cavity;

[0062] The negative pressure mechanism 20 is installed in the installation cavity and is configured to drive the liquid to enter from the liquid inlet 121 and be discharged from the liquid outlet 111, thereby generating negative pressure in the installation cavity so that the pressure outside the housing 10 is greater than the pressure inside the installation cavity, thereby achieving the housing 10 being adsorbed on the fish tank wall 210;

[0063] The cleaning mechanism 30 includes a cleaning wheel 31 and a first drive motor 32 connected thereto, wherein the cleaning wheel 31 is pivotally arranged on the housing 10, and when the fish tank cleaning device 100 is adsorbed on the fish tank wall 210, the cleaning wheel 31 is abutted against the fish tank wall 210.

[0064] That is to say, Figure 3 As shown, the fish tank cleaning device 100 is placed in the fish tank 200, and the negative pressure mechanism 20 generates negative pressure in the installation cavity so that the pressure outside the shell 10 is greater than the pressure in the installation cavity, thereby achieving the adsorption of the shell 10 on the fish tank wall 210; then the first drive motor 32 drives the cleaning wheel 31 to rotate, and the cleaning wheel 31 can move forward or backward while cleaning the fish tank wall 210 by relying on the friction between the fish tank wall 210; the fish tank cleaning device 100 has strong adsorption, can easily clean the fish tank wall 210, and has a simple structure and high reliability.

[0065] In one example of the present invention, the negative pressure mechanism 20 includes:

[0066] Negative pressure impeller, not shown in the figure;

[0067] A second driving motor 21, whose output shaft is connected to the negative pressure impeller, is configured to drive the negative pressure impeller to rotate and generate negative pressure in the installation cavity;

[0068] That is to say, the second drive motor 21 drives the negative pressure impeller to rotate. During the rotation of the negative pressure impeller, negative pressure will be generated in the installation cavity. At this time, the water outside the shell 10 will automatically flow into the installation cavity, thereby pushing the shell 10 and achieving the adsorption of the shell 10 on the fish tank wall 210.

[0069] In one example of the present invention, Figure 2 As shown, the liquid inlet 121 is opened on a side of the housing 10 close to the cleaning mechanism 30, the liquid outlet 111 is opened on a side of the housing 10 away from the cleaning mechanism 30, and a filter screen is provided on the upper cover of the liquid outlet 111;

[0070] As water flows into the liquid inlet 121 and water is discharged from the liquid outlet 111, a negative pressure is generated in the installation cavity, so an adsorption force is formed at the liquid inlet 121. The liquid inlet 121 is arranged on the side of the shell 10 close to the cleaning mechanism 30, so that the fish tank cleaning device 100 can be adsorbed onto the fish tank wall 210, so that the cleaning wheel 31 fits on the fish tank wall 210; the liquid outlet 111 is arranged on the side of the shell 10 away from the cleaning mechanism 30, and its position is opposite to the liquid inlet 121, and does not affect the normal operation of the fish tank cleaning device 100, and the filter net can prevent impurities in the fish tank 200 from entering the cleaning mechanism 30 and affecting its normal operation, thereby protecting the cleaning mechanism 30.

[0071] In one example of the present invention, Figure 1 and Figure 2 As shown, the cleaning wheel 31 includes two coaxially arranged and mutually independent roller parts 311, and each of the roller parts 311 is equipped with a first driving motor 32;

[0072] Specifically, a rotating shaft 112 is provided on the main body 11, and two roller parts 311 are respectively mounted on the rotating shaft 112, and are respectively driven to rotate by designated first drive motors 32; when it is necessary to move forward in a straight line, the two first drive motors 32 rotate at the same speed; when it is necessary to turn, the two first drive motors 32 move differentially, and the turning of the fish tank cleaning device 100 is achieved through the differential movement, further facilitating its movement in the fish tank 200.

[0073] In one example of the present invention, Figure 4 As shown, it also includes: a controller 50,

[0074] It is coupled to the negative pressure mechanism 20 and is configured to control the negative pressure mechanism 20 to perform a corresponding adsorption action;

[0075] It is coupled to the cleaning mechanism 30 and is configured to control the cleaning mechanism 30 to perform a cleaning action;

[0076] The fish tank cleaning device 100 is placed in the fish tank 200, and the controller 50 controls the negative pressure mechanism 20 to generate negative pressure in the installation cavity so that the pressure outside the shell 10 is greater than the pressure in the installation cavity, so that the shell 10 is adsorbed on the fish tank wall 210; then the controller 50 controls the first driving motor 32 to drive the cleaning wheel 31 to rotate, and the cleaning wheel 31 can move forward or backward while cleaning the fish tank wall 210 by relying on the friction between the cleaning wheel 31 and the fish tank wall 210;

[0077] It should be noted that by controlling the forward and reverse rotation of the cleaning mechanism 30 , the fish tank cleaning device 100 can be moved forward and backward.

[0078] In one example of the present invention, Figure 4 As shown, it also includes: a collision sensor 60,

[0079] It is mounted on the housing 10 and configured to sense that the fish tank cleaning device 100 touches the side wall of the fish tank and generates a rotation signal;

[0080] The collision sensor 60 is coupled to the controller 50 and is configured to receive the rotation signal and control the fish tank cleaning device 100 to rotate a certain angle;

[0081] That is to say, after the fish tank cleaning device 100 collides with the side wall, the controller 50 controls the first drive motor 32 on the two coaxially arranged roller parts 311 to rotate differentially, thereby realizing the turning of the fish tank cleaning device 100; for example, the differential motion can be used to rotate 180 degrees, so that the fish tank cleaning device 100 can move in a "Z"-shaped route to achieve cyclic reciprocating cleaning and better cleaning effect.

[0082] In one example of the present invention, Figure 4 As shown, it also includes: a water level monitor 70,

[0083] It is installed on the housing 10 and is configured to monitor the water level signal of the fish tank cleaning device 100 in the fish tank 200;

[0084] The water level monitor 70 is coupled to the controller 50 and is configured to receive the water level signal and control the cleaning device to be below the water level;

[0085] The water level signal of the fish tank cleaning device 100 in the fish tank 200 is monitored in real time by the water level monitor 70, so that the controller 50 controls the fish tank cleaning device 100 to move below the water level. For example, when the fish tank cleaning device 100 moves close to the liquid surface, the controller 50 controls the fish tank cleaning device 100 to stop moving in this direction and controls the cleaning mechanism 30 to move in the opposite direction. In this way, it can be ensured that the fish tank cleaning device 100 is always below the water surface, avoiding it from floating on the water surface and affecting its adsorption on the fish tank wall 210, so that the fish tank cleaning device 100 can continuously and effectively clean the fish tank wall 210, thereby improving the reliability and stability of the fish tank cleaning device 100.

[0086] In one example of the present invention, Figure 4 As shown, it also includes: an attitude angle monitor 80,

[0087] configured to monitor the position and posture of the fish tank cleaning device 100 to determine whether the fish tank cleaning device 100 is located at the bottom wall or the side wall of the bathtub;

[0088] The position of the fish tank cleaning device 100 can be understood in real time through the attitude angle monitor, so as to better perform corresponding cleaning actions on the fish tank cleaning device 100;

[0089] Affected by the 90-degree right angle between the side walls, it is difficult for the fish tank cleaning device 100 to climb between the side walls. Generally, when the fish tank cleaning device 100 switches between adjacent fish tank walls, it climbs from the bottom wall to the side wall. The attitude angle monitor 80 can well determine the position of the fish tank cleaning device 100, thereby facilitating the execution of corresponding actions.

[0090] In one example of the present invention, Figure 4 As shown, it also includes: a wireless connection module 90,

[0091] It is coupled to the controller 50 and is configured to control the fish tank cleaning device 100 to perform corresponding actions through the mobile phone communication terminal;

[0092] For example, the wireless connection module 90 includes Bluetooth and Wifi;

[0093] That is, the mobile phone is connected to the fish tank cleaning device 100 through Bluetooth or Wifi, so that the mobile phone communication terminal can control the fish tank cleaning device 100 to perform corresponding actions.

[0094] In one example of the present invention, Figure 2 As shown, the housing 10 includes:

[0095] The body portion 11 has an open cavity with one open end;

[0096] A bottom plate portion 12, covering the open end and defining a mounting cavity together with the open cavity;

[0097] The bottom plate portion 12 and the main body portion 11 may be fastened together by a fastener, such as a bolt.

[0098] Preferably, the main body 11 is an arc-shaped structure.

[0099] Preferably, the liquid inlet 121 includes two, and is arranged in a diagonal structure on the shell; that is, the liquid inlet 121 is opened on the bottom plate portion 12, and the two liquid inlets 121 are arranged diagonally, so that the negative pressure adsorption force in the shell 10 can be more stable, which helps to stabilize the movement of the fish tank cleaning device 100.

[0100] In one example of the present invention, Figure 2 As shown, it also includes: a filter bag 40,

[0101] The filter bag 40 is wrapped around the outside of the negative pressure mechanism 20 and is configured to filter the excrement in the fish tank 200;

[0102] The filter bag 40 can protect the negative pressure mechanism 20, preventing impurities in the fish tank 200 from entering the negative pressure mechanism 20, thereby affecting the normal operation of the negative pressure mechanism 20, and protecting the negative pressure mechanism 20. It can be understood that the filter bag 40 is provided with filter holes, and the excrement in the fish tank 200 is filtered through the filter holes.

[0103] In one example of the present invention, Figure 1 and Figure 2 As shown, the cleaning mechanism 30 includes two, and is symmetrically arranged on both sides of the housing 10;

[0104] By providing two cleaning mechanisms 30, the fish tank cleaning device 100 can achieve better cleaning effects, better balance and better stability during walking. It is understandable that the two cleaning mechanisms 30 rotate in the same direction, thereby ensuring that the fish tank cleaning device 100 can move in the same direction.

[0105] The exemplary implementation of the fish tank cleaning device 100 proposed in the present invention is described in detail above with reference to the preferred embodiments. However, those skilled in the art will appreciate that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the protection scope of the present invention, which is determined by the attached claims.
