Description

Technical Field

[0001] The utility model relates to the field of water container cleaning, in particular to a sand washer. Background Art

[0002] To enrich their daily lives, more and more people are raising ornamental fish. However, after a while, fish waste and feces will adhere to the surface of the sand and water at the bottom of the tank. Over time, this can cause the water in the tank to become turbid, affecting the normal life of the fish. Therefore, cleaning the sand and water at the bottom of the tank and changing the water have become essential tasks for raising ornamental fish.

[0003] According to the above situation, it can be known that there are roughly two situations for cleaning the fish tank. One is that the water is not turbid, but there are more sediments at the bottom of the fish tank. The other situation is that there are too many sediments, which has caused the water to be turbid. In the prior art, for the situation where the water is not turbid but there are too many sediments, a scoop net is often used to salvage or directly change the water, which is inefficient and wastes resources. For the turbid water, the water is changed by pumping. Therefore, the prior art can only use some tools to assist in completing one of the above situations. If the fish tank cleaning is to adapt to various situations, it is necessary to use multiple independent tools. Therefore, in order to be able to not only clean the sediment at the bottom of the fish tank, but also complete the water change in the fish tank, it is very necessary to provide a sand washer. Utility Model Content

[0004] The purpose of the utility model is to provide a sand washer that can adapt to a variety of situations when cleaning a fish tank, and can conveniently and efficiently clean the fish tank in different situations, so as to solve the existing technical defects and unmet technical requirements.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sand washer, comprising:

[0006] A driving motor, the driving motor being connected to a water inlet pipe and a water outlet pipe, the water inlet pipe being connected to a sand filter for filtering and storing sand and gravel in the water;

[0016] The blocking member rotates following the switching member to block the first adapter and the second adapter.

[0017] In the present application, it is necessary to emphasize that the explanation of the bottom wall and side wall of the switching cavity is based on the switching component itself as a direction reference, that is, the accommodating cavity itself, rather than the upper and lower directions described later as the same reference standard. The upper and lower directions below are used as a reference based on the present application as a whole. The difference between the two is that the reference basis itself is not affected by the overall placement position and direction of its own components.

[0018] Preferably, the switching element includes:

[0019] A rotating sealing cover, wherein the rotating sealing cover is rotatably connected to the inner side wall of the switching chamber, and the rotating sealing cover and the inner side wall of the switching chamber are sealed by a sealing member;

[0020] an adjusting portion connected to the rotary sealing cover and used for adjusting the rotation of the rotary sealing cover;

[0021] A connecting shaft, one end of which is fixed to an end of the rotary sealing cover away from the adjusting portion, the other end of which is rotatably connected to the bottom wall of the switching chamber, and the blocking member is connected to the connecting shaft.

[0022] Preferably, at least two limiting portions are circumferentially distributed on the outer side wall of the connecting shaft, and a limiting space is formed between adjacent limiting portions;

[0023] An accommodating cavity is provided inside the connecting shaft, and a connecting groove is provided on the outer side wall of the connecting shaft, and the accommodating cavity is connected with the limiting space through the connecting groove;

[0024] The blocking member includes a first connecting portion and a blocking portion, wherein the first connecting portion is arranged on the blocking portion and is sleeved in the accommodating cavity. The blocking portion is abutted against the limiting portion and is located in the limiting space, and one end surface of the blocking portion can block the first adapter interface or the second adapter interface.

[0025] Preferably, the water inlet pipe is composed of multiple sections of short water inlet pipes connected in sequence, and the sand filter is arranged between two adjacent short water inlet pipes;

[0026] The sand filter comprises:

[0027] A sand filter body, wherein the interior of the sand filter body is hollow;

[0031] A filter screen connected to the inner wall of the sand filter body and located between the upper end surface of the sand filter body and the upper end surface of the water delivery portion;

[0032] The sand storage part is surrounded by a filter screen, an inner wall of a sand filter body, an outer wall of a water delivery part and an outer wall of a recessed third connecting part.

[0033] In the present application, it should be emphasized that the upper and lower parts mentioned in the text are used as a reference for the present application as a whole, that is, the upper and lower parts of the whole rather than the individual components themselves as a reference, because the placement and direction of the individual components in the whole are different. For example, the switching cavity mentioned above, the direction reference of the switching cavity is based on itself as a reference, which is different from the overall reference here.

[0034] It should also be noted that the connection between the filter screen and the inner wall of the sand filter body can be understood as the connection between the circumferential outer wall of the filter screen and the inner wall of the sand filter body, and the cross-section of the filter screen covers the cross-section of the hollow part of the sand filter body, which is used to achieve a blocking effect on the sediment in the water flow through the hollow part. Although the connection between the filter screen and the sand filter body is relatively common, it is not specifically described in the above definition to avoid ambiguity and clarity, so it is further explained here. In addition, in this application, except for the special emphasis on taking itself as the basis for reference, the other up and down are based on the overall direction of this application.

[0035] And for the definition of the outer wall of the third connecting part, the outer here is also based on the third connecting part itself, that is, the part of the recessed third connecting part that contacts the water inlet short pipe is the inner wall, and the part constituting the sand storage part is the outer wall. However, from the overall point of view, the outer part of the third connecting part used to constitute the sand storage part is actually inside relative to the water inlet short pipe as a whole, that is, it is closer to the center of the sand filter body. Therefore, the expressions selected with different references are different, but the meaning expressed is the same. In order to avoid ambiguity and clarity, additional explanations are provided here.

[0036] Preferably, a cleaning member is connected to the water inlet of the water inlet pipe, and the cleaning member includes:

[0037] a fourth connecting portion, wherein a first water inlet channel is provided on the fourth connecting portion, and one end of the fourth connecting portion is connected to the water inlet of the water inlet pipe, and the first water inlet channel is in communication with the interior of the water inlet pipe;

[0038] a fifth connecting portion, wherein a second water inlet channel is provided on the fifth connecting portion, and one end of the fifth connecting portion is connected to an end of the fourth connecting portion away from the water inlet pipe, and the second water inlet channel is in communication with the first water inlet channel;

[0039] The cleaning parts are evenly distributed on one end of the fifth connecting part away from the fourth connecting part, and the opening of the second water inlet channel on the end surface of the fifth connecting part is located between the cleaning parts.

[0040] In the present application, it should be noted that the first water inlet channel and the second water inlet channel are not completely closed, that is, there are openings at both ends of the fourth connecting part or the fifth connecting part. Therefore, it is said above that the opening of the second water inlet channel on the end face of the fifth connecting part is located between several cleaning parts. It can be understood that the second connecting channel is provided with an opening on the end face of the fifth connecting part away from the fourth connecting part, and several cleaning parts are provided around this opening.

[0041] In addition, it was mentioned in the previous text that the first water outlet branch pipe can discharge water into the container where the water inlet on the water inlet pipe is located, and the second water outlet branch pipe can discharge water into a container different from the container where the water inlet on the water inlet pipe is located. Its main meaning is the container where the water inlet at the lowest end of the entire application is located. However, because the setting of the cleaning part was not mentioned in the previous text, that is, the water inlet of the water inlet pipe in the above text is the water inlet at the lowest end of the entire device, but the setting of the cleaning part is added here, so the overall lowest water inlet place in this application becomes the lower end of the second water inlet channel, that is, the opening in the middle of the several cleaning parts mentioned above. After the addition of the cleaning part, there is a height difference between the water inlet of the water inlet pipe mentioned above and the opening in the middle of the cleaning part. Therefore, it is explained here that after the cleaning part is added to this application, the meaning of the container where the water inlet is located mentioned above becomes the container where the opening in the middle of the cleaning part is located.

[0042] Preferably, a switch is further included, the switch being electrically connected to the drive motor, and the switch includes:

[0043] An acceleration button, which is used to control the drive motor to increase operating power;

[0044] A deceleration button, which is used to control the drive motor to reduce operating power;

[0045] A switch button is used to control the start and stop of the operation of the drive motor.

[0046] Preferably, it comprises a main body, the main body comprising a handle and an extension arm, the handle being arranged at the upper end of the extension arm;

[0047] The driving motor, water outlet assembly, switching assembly and water outlet pipe are all arranged inside the handle, and the switch is located on the outer wall of the handle;

[0048] The upper end of the water inlet pipe extends into the interior of the handle and is connected to the drive motor, and the other end extends in a direction away from the handle and is used together with the sand filter and the cleaning piece as an extension arm.

[0049] Preferably, a first drain outlet and a second drain outlet are provided on the handle, and an end of the first water outlet branch pipe away from the adapter extends toward the extension arm to the first drain outlet, and an end of the second water outlet branch pipe away from the adapter extends toward the end of the handle away from the extension arm to the second drain outlet, and is connected to a conversion head.

[0050] Compared with the prior art, the beneficial effects of the present invention are:

[0051] 1. The present application sets a switching component and a water outlet component, and the water sucked into the water inlet pipe can be discharged to different positions through the first water outlet branch pipe and the second water outlet branch pipe. By setting the switching component, the water can be discharged into the corresponding position according to the usage. That is, if only the mud and sand at the bottom of the tank are cleaned during operation and the water does not need to be changed, the second water outlet branch pipe is blocked by the switching component, so that the water after the mud and sand are filtered is discharged back into the fish tank through the first water outlet branch pipe. If the water needs to be changed, the first water outlet branch pipe is blocked by the switching component, and the water after the mud and sand are filtered is discharged from the second water outlet branch pipe to other containers outside the fish tank, so as to improve the adaptability, convenience and efficiency of the present application.

[0052] 2. The present application is also provided with a sand filter, which can be understood as the third connecting part and the water supply part in the sand filter forming an "inverted funnel". The silt in the water passing through the sand filter body is filtered out through the setting of the filter screen, and then stored in the sand storage part composed of the "inverted funnel" and the inner wall of the sand filter body to achieve filtering and collection of the silt. Moreover, the setting of the second connecting part and the third connecting part in the present application can make the installation and disassembly of the sand filter more convenient, so as to facilitate the cleaning of the silt collected in the sand storage part.

[0053] 3. The present application completes the water transportation through the driving motor, completes the filtration and storage of the sediment in the water through the sand filter, and is provided with a switch with a gear adjustment function and a control function, so that the present application has the characteristics of high efficiency, convenience and easy operation in cleaning the fish tank.

DETAILED DESCRIPTION

[0069] The following is a combination of the appended examples of the present invention Figure 1-14 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0070] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0071] See also Figure 1-14 , embodiments of the present utility model:

[0072] Example:

[0073] like Figure 2 and 7 Shown: A sand washer, comprising:

[0074] A driving motor 1 is connected to a water inlet pipe 2 and a water outlet pipe 3. The water inlet pipe 2 is connected to a sand filter 4 for filtering and storing sand and gravel in the water;

[0075] A switching assembly connected to an end of the water outlet pipe 3 away from the drive motor 1;

[0076] A water outlet assembly, which is connected to the switching assembly and includes a first water outlet branch pipe 5 and a second water outlet branch pipe 6;

[0077] The switching assembly is used to control water to flow out from the first water outlet branch pipe 5 or the second water outlet branch pipe 6 .

[0078] Specifically, in this embodiment, the driving motor 1 is powered by directly connecting to the power supply around the water tank through the wire 53 .

[0079] In this embodiment, by setting a switching component and a water outlet component, the water sucked into the water inlet pipe 2 can be discharged to different positions through the first water outlet branch pipe 5 and the second water outlet branch pipe 6. By setting the switching component, the water can be discharged into the corresponding position according to the usage. That is, if only the mud and sand at the bottom of the tank are cleaned during work and there is no need to change the water, the second water outlet branch pipe 6 is blocked by the switching component, so that the water after filtering the mud and sand is discharged back into the fish tank through the first water outlet branch pipe 5. If the water needs to be changed, the first water outlet branch pipe 5 is blocked by the switching component, and the water after filtering the mud and sand is discharged from the second water outlet branch pipe 6 to other containers outside the fish tank, so as to improve the adaptability, convenience and efficiency of this application.

[0083] The first water outlet branch pipe 5 can discharge water into a container where the water inlet on the water inlet pipe 2 is located, and the second water outlet branch pipe 6 can discharge water into a container different from the container where the water inlet on the water inlet pipe 2 is located.

[0084] Specifically, in this embodiment, the setting of the switching chamber 8 can provide partial water storage space and switching space, so that the switching is smoother.

[0085] like Figure 9 As shown: a first adapter port 11 and a second adapter port 12 are provided on the side wall of the switching chamber 8, wherein the first adapter port 11 is connected to the first water outlet branch pipe 5, and the second adapter port 12 is connected to the second water outlet branch pipe 6;

[0086] A water inlet connection port 13 is provided on the bottom wall of the switching chamber 8, and the water inlet connection port 13 is connected to the water outlet pipe 3;

[0087] The blocking member 10 rotates along with the switching member 9 to block the first adapter port 11 and the second adapter port 12 .

[0088] Specifically, the switching member 9 is configured as a hollow cylinder, and based on itself as a reference, its upper end is open for connection between the adapter 7 and the switching member 9, and the side wall of the switching cavity 8 is arc-shaped, and is provided with a fixed cover 44 for stable connection between the adapter 7 and the switching member 9, ensuring that the switching member 9 can be better connected with the adapter 7 in the vertical direction. Of course, the vertical direction here is also based on the adapter 7 itself as a reference.

[0089] In this embodiment, the blocking switching between the first adapter 11 and the second adapter 12 is conveniently completed by rotating the switching member 9 .

[0090] like Figure 10 As shown: the switching member 9 includes:

Specifically, the rotation groove 45 is provided at the center of the bottom wall of the switching chamber 8, and the water inlet connection port 13 is opened on one side of the rotation groove 45 to avoid the conflict between the rotation and the water inlet. In addition, the outer surface of the rotating sealing cover 14 is provided with an adjusting portion 16, and the adjusting portion 16 has a plurality of stripes distributed circumferentially to increase the contact with the finger. The friction between them is convenient for adjustment, and the connecting shaft 17 is arranged on the inner surface of the rotating sealing cover 14. As for the arrangement of the sealing member 15, a sealing groove is provided in the circumferential direction of the rotating sealing cover 14, that is, on the surface of the rotating sealing cover 14 facing the inner wall of the switching chamber 8, and the sealing member 15 is installed in the sealing groove. The sealing member 15 is specifically arranged as an annular rubber ring. By arranging the sealing member 15 on the rotating sealing cover 14 and between the rotating sealing cover 14 and the inner wall of the switching chamber 8, when the rotating sealing cover 14 rotates relative to the adapter 7, it can still prevent the water in the switching chamber 8 from flowing out, that is, it has the effect of rotating sealing.

[0095] The adjustment portion 16 extends out of the handle 38 to facilitate switching and adjustment.

[0096] like Figure 8-10 As shown: two limiting portions 18 are circumferentially distributed on the outer side wall of the connecting shaft 17, and a limiting space 19 is formed between adjacent limiting portions 18;

[0097] An accommodating cavity 20 is provided inside the connecting shaft 17, and a connecting groove 21 is provided on the outer wall of the connecting shaft 17. The accommodating cavity 20 is connected to the limiting space 19 through the connecting groove 21.

The first end 22 of the first connecting portion 22 is inserted into the accommodating cavity 20. The first end 22 of the first connecting portion 22 is inserted into the accommodating cavity 20. The first end 22 of the first connecting portion 22 is inserted into the accommodating cavity 20. The first

[0100] Specifically, a plurality of water retaining portions 46 are provided on the circumferential direction of the outer wall of the connecting shaft 17. Regardless of whether it is the water retaining portion 46, the limiting portion 18 or the blocking member 10, a certain distance is set between the above three and the bottom wall of the switching chamber 8, and a certain distance is also left between the water retaining portion 46 and the side wall of the accommodating chamber 20. The space generated by these two distance settings is only for facilitating the flow of water in the accommodating chamber 20. The setting of the water retaining portion 46 can first buffer the water flow flowing in from the water inlet connection port 13, and can also increase the stability of the switching member 9 during rotation.

[0101] like Figure 4 、 5 , 11 and 12: the water inlet pipe 2 is composed of multiple short water inlet pipes connected in sequence, and the sand filter 4 is arranged between two adjacent short water inlet pipes;

[0102] The sand filter 4 includes:
