Description

Technical Field

[0001] This utility model belongs to the technical field of ventilation devices, and relates to a ground-mounted small and medium-sized water tank, and more particularly to a ground-mounted small and medium-sized ventilation water tank. Background Technology

[0002] Ventilation, also known as air exchange, is the process of mechanically or naturally introducing sufficient fresh air into an indoor space while simultaneously expelling polluted air that does not meet hygiene requirements, so that the indoor air meets hygiene requirements and the needs of the production process. All facilities in a building that perform ventilation are collectively referred to as ventilation devices.

[0003] Currently, some water tanks have ventilation holes on the top, but this is a passive air intake method. Over time, the air inside the water tank will still become polluted, causing bacteria to grow and thus contaminating the water source.

[0004] Some water tanks have intake and exhaust fans inside. If the ventilation volume is too large during use, it may cause excessive loss of water vapor inside the tank, resulting in waste of water resources. If the exhaust volume is too small, it may not be able to meet the normal ventilation needs of the water tank, which may lead to the risk of pressure buildup inside the tank.

[0005] In summary, existing water tanks cannot precisely control the ventilation volume under different usage conditions, resulting in excessive ventilation leading to energy waste, or insufficient ventilation failing to meet the air replacement needs inside the water tank. This is not only detrimental to the water quality and environment inside the tank, but also easily leads to dampness and mold growth inside the tank, and may even affect water quality safety. Summary of the Invention

[0006] In view of the shortcomings of existing technologies, such as the lack of a structure to control the air volume, which makes the water in the tank prone to dampness and mold, affecting water quality and safety, this utility model provides a ventilated water tank.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A ventilation water tank includes a tank body, a drain valve, a ventilation pipe, a housing, an adjusting handle, a bearing seat, an adjusting valve, a pin, a filter box, and an exhaust fan. The adjusting valve includes a front toothed groove, a circular plate structure with a shaft, and a valve end connected in sequence. The circular plate structure with a shaft matches the cross-sectional size of the ventilation pipe. The ventilation pipe is provided through the top of the tank body. A housing is fixed to one side of the ventilation pipe, and the front toothed groove is placed inside the housing. An adjusting handle is provided outside the housing, and the adjusting handle is fixedly connected to the front toothed groove. A bearing seat is fixed to the opposite side of the ventilation pipe, and the valve end is rotatably connected inside the bearing seat. A sliding groove is provided inside the housing, and the pin is slidably connected inside the sliding groove. The front end of the pin is inserted into the front toothed groove to limit the rotation angle of the adjusting valve. A filter box is installed through the top of the ventilation pipe, and an exhaust fan is provided inside the filter box. A filter mechanism that can be quickly replaced is provided above the exhaust fan.

[0009] Furthermore, the front part of the pin is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to the inner wall of the slide groove.

[0010] Furthermore, the inner wall of the slide is provided with first limiting grooves on both sides, and the movement space of the pin is fixed when the two sides of the pin move on the inner wall of the first limiting groove.

[0011] Furthermore, the front end of the pin is configured as a spike, which matches the front tooth groove.

[0012] Furthermore, the edges of the circular plate-like structure with shaft are fitted with sealing gaskets.

[0013] Furthermore, a second limiting groove is provided on the inner wall of the housing, and a guide block is rotatably connected to the inner wall of the second limiting groove. The guide block is fixedly connected to the adjusting handle outward and connected to the outer side of the front tooth groove of the adjusting valve inward.

[0014] Furthermore, the filter box has an internal mounting groove, and a bracket is slidably connected to the inner wall of the mounting groove. A replaceable filter pad is placed inside the bracket.

[0015] Furthermore, extension blocks are fixedly connected to both sides of one end of the filter box, and the extension blocks have vertically oriented strip-shaped cavities. The lower end of the extension block is rotatably connected to a clamping block via a pivot. The clamping block has an L-shaped structure, and its insertion end is inserted into the slot at the front end of the bracket. The sliding buckle has a symmetrical hook-shaped structure. The hook at the end of the sliding buckle is inserted into the aforementioned cavity of the extension block and can slide up and down within the cavity. Moreover, when the clamping block is rotated to the upward direction, the clamping block is located on the inner wall of the hook of the sliding buckle and is limited.

[0016] The advantages of this utility model are as follows:

[0017] (1) By using this utility model, by rotating the adjustment handle to drive one end of the adjustment valve, the other end of the adjustment valve will rotate inside the ventilation pipe through the bearing inside the bearing base. By rotating the adjustment valve to an appropriate angle, ventilation is provided inside the water tank body, and floating dust and some other dust are drawn into the interior of the exhaust fan and then filtered by the filter screen on the top of the exhaust fan before being discharged.

[0018] This invention allows for precise control of ventilation volume by adjusting the rotation angle of the regulating valve by twisting the adjusting handle.

[0019] (2) This utility model can adjust the angle of the regulating valve by rotating it, which can also meet the ventilation needs of different usage scenarios and improve the practicality and flexibility of water tank ventilation. For example, in the hot summer weather, in order to enhance the heat dissipation effect inside the water tank, the regulating valve can be adjusted to the maximum ventilation angle to maximize the air flow; while in the spring and autumn seasons, the ventilation angle of the regulating valve can be appropriately reduced to reduce noise.

[0020] (3) Moreover, the present invention provides a pin in the front tooth groove of the regulating valve. Before adjusting the rotation angle of the regulating valve, the pin needs to be pulled out to release the limit. After the main body of the regulating valve is adjusted to the rotation angle, the pin is pushed to automatically return to its original position. At this time, the front end of the pin is inserted into other tooth grooves at the front end of the regulating valve to limit and fix it, so as to prevent the rotation angle of the main body of the regulating valve from changing when the exhaust fan is ventilating, thus affecting the accurate control of the ventilation volume.

[0021] (4) In this utility model, a filter pad that can be quickly replaced is provided, which ensures ventilation efficiency and durability. Moreover, the replacement process does not require complicated tools or professional skills, which greatly improves the practicality of the equipment. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0029] Reference Figures 1 to 5 As shown, the ventilation water tank in this embodiment includes a water tank body 1, a drain valve 2, a ventilation pipe 3, a shell 4, an adjusting handle 5, a bearing base 6, an adjusting valve 7, a pin 9, a filter box 10, and an exhaust fan 11.

[0030] The water tank body 1 has a drain valve 2 at the bottom of one side and a water supply pipe at the top. When the water inside the water tank body 1 is replaced by drain valve 2, water is then refilled through the water supply pipe to achieve water replenishment. A ventilation pipe 3 runs through the top of the water tank body 1.

[0031] Among them, such as Figure 3 As shown, the regulating valve 7 includes a front toothed groove, a plate-like structure with a shaft as its main body, and an end. The plate-like structure with a shaft is matched and adapted to the cross-section of the ventilation pipe 3.

[0032] Preferably, the edge of the plate-like structure with shaft is fitted with a sealing gasket 15. When the user needs to close the ventilation pipe 3, the regulating valve 7 is rotated to the flat surface, and the sealing gasket 15 will block the gap between the regulating valve 7 and the ventilation pipe 3, thereby improving its sealing performance.

[0033] The ventilation pipe 3 is fixedly connected to a housing 4 on one side. The front toothed groove of the regulating valve 7 is placed inside the housing 4. An adjusting handle 5 is provided outside the housing 4. The adjusting handle 5 is fixedly connected to the front toothed groove of the regulating valve 7.

[0034] A bearing base 6 is fixedly connected to the opposite side of the ventilation duct, and the end of a regulating valve 7 is rotatably connected inside the bearing base 6.

[0035] By rotating the adjusting handle 5, the front tooth groove of the adjusting valve 7 is driven to rotate, and the end of the adjusting valve 7 also rotates through the bearing inside the bearing base 6, so that the plate-like structure with shaft of the main body of the adjusting valve 7 rotates inside the ventilation pipe 3.

[0036] Among them, such as Figure 4 As shown, the interior of the housing 4 is provided with a sliding groove 8 (such as...). Figure 3 and Figure 4 As shown, a pin 9 is slidably connected to the inner wall of the slide groove 8. The outer end of the pin 9 can be inserted into the front tooth groove of the regulating valve 7 to limit and fix the regulating valve 7 and prevent the regulating valve 7 from rotating again.

[0037] Preferably, the front end of the pin 9 is set as a spike, which matches the front tooth groove of the regulating valve 7.

[0038] Preferably, one end of the first spring 12 is fixedly connected to the front part of the pin 9, and the other end of the first spring 12 is fixedly connected to the inner wall of the slide groove 8. When the front end of the pin 9 is disengaged from the front tooth groove of the regulating valve 7, the first spring 12 is compressed by pulling the pin 9 upward. When the pin 9 is released, the first spring 12 is released and rebounds, pushing the pin 9 so that the pin 9 is inserted into the front tooth groove again. The operation steps are reduced by the first spring 12, making the operation simpler.

[0039] Preferably, the inner wall of the slide groove 8 is provided with first limiting grooves 13 on both sides. When the two sides of the pin 9 move along the inner wall of the first limiting groove 13, the movement space of the pin 9 is fixed, preventing it from falling out during movement. More preferably, the inner wall of the first limiting groove 13 is slidably connected with limiting blocks 14. The limiting blocks 14 are engaged and fixed with the first pin 9. When the pin 9 moves along the inner wall of the first limiting groove 13 through the limiting blocks 14 on both sides, the movement space of the pin 9 is fixed, preventing it from falling out during movement.

[0040] Preferably, the inner wall of the housing 4 is further provided with a second limiting groove 16. The second limiting groove 16 is located on the side near the adjusting handle 5. A guide block 17 is rotatably connected to the inner wall of the second limiting groove 16. The outer side of the guide block 17 is fixedly connected to the adjusting handle 5, and the inner side of the guide block 17 is connected to the outer side of the front tooth groove of the regulating valve 7. When the user rotates the adjusting handle 5, the guide block 17 prevents the adjusting handle 5 from coming out of the housing 4 during user operation. The guide block 17 also improves the stability of operation when adjusting the angle of the regulating valve 7. The adjusting handle 5 is used in an environment with large vibrations, and the connection between the handle and the valve body may loosen. The second limiting groove 16 and the guide block 17 can play a role in fixing, stabilizing, and guiding.

[0041] The top of the ventilation duct 3 is fitted with a filter box 10, and an exhaust fan 11 is installed inside the filter box 10. A replaceable filter pad 20 is installed above the exhaust fan 11.

[0042] Reference Figure 5 As shown, the filter box 10 has an installation groove 18 inside, and a bracket 19 is slidably connected to the inner wall of the installation groove 18. A filter pad 20 is placed inside the bracket 19, and the filter pad 20 can be quickly pulled out and replaced.

[0043] Preferred, such as Figure 5As shown, extension blocks 21 are fixedly connected to both sides of one end of the filter box 10. Each extension block 21 has a vertically oriented strip-shaped cavity. A clamping block 22 is rotatably connected to the lower end of the extension block 21 via a pivot. The clamping block 22 has an L-shaped structure, and one end (insertion end) of the clamping block 22 is inserted into a groove at the front end of the bracket 19. A sliding buckle 23 has a symmetrical hook-shaped structure. The hook at the end of the sliding buckle 23 inserts into the cavity of the extension block 21 and can slide up and down within the cavity. Furthermore, the inner wall of the hook of the sliding buckle 23 is slidably connected to the surface of the clamping block 22 (when the clamping block 22 rotates to the upward direction, the clamping block 22 is positioned within the inner wall of the hook of the sliding buckle 23).

[0044] When the user finds that the filter pad 20 needs to be replaced after using the water tank for a long time, the user moves the sliding buckle 23 upward along the strip cavity of the extension block 21. At this time, the clamping block 22 is no longer restricted and can be unfolded to both sides. The clamping block 22 is rotated along the pivot so that one end (insertion end) is dislodged from the groove at the front end of the bracket 19. The filter pad 20 is replaced by removing the bracket 19. This ensures the ventilation efficiency of the equipment, while also taking into account stability and durability. Moreover, the replacement process does not require complicated tools or professional skills, which greatly improves the practicality of the equipment.

[0045] More preferably, the upper part of the hook of the sliding buckle 23 is fixedly connected to the lower end of the second spring 24, and the upper end of the second spring 24 is fixedly connected to the inner cavity of the extension block 21. When the user moves the sliding buckle 23 along the inner wall of the extension block 21, the sliding buckle 23 squeezes the second spring 24, causing it to store and compress. At this time, the user can remove the bracket 19. After the user installs the filter pad 20, the user can release the sliding buckle 23 to allow the second spring 24 to release and rebound, thus re-restraining the clamping block 22. The operation of the device is made simpler by the second spring 24.

[0046] The working principle of the ventilation water tank in this embodiment is as follows:

[0047] When ventilation is required inside the water tank body 1, the user first moves the latch 9 upwards (e.g., Figure 3 (As shown in the upward direction) slides along the inner wall of the slide groove 8, thereby disengaging the pin 9 from the toothed groove at the front end of the regulating valve 7, thus releasing the fixing of the regulating valve 7;

[0048] Then, by rotating the adjusting handle 5, the front end of the adjusting valve 7 is rotated, thereby rotating the main body of the adjusting valve 7 and the other end of the adjusting valve 7 rotating with the bearing inside the bearing base 6. When the main body of the adjusting valve 7 is rotated to an appropriate angle, the exhaust fan 11 is activated to ventilate the inside of the water tank body 1. Dust and other impurities in the air are sucked into the exhaust fan 11. When the adjusting handle is rotated to 0-10 degrees, the ventilation volume is 100-200 cubic meters / hour, which can meet the basic ventilation needs inside the water tank body 1, while avoiding excessive ventilation that causes water to evaporate too quickly. If the adjusting handle is rotated to 10-20 degrees, the ventilation volume will increase accordingly, with an air volume of 200-400 cubic meters / hour, which is suitable for scenarios where the humidity inside the water tank body 1 is high or where rapid ventilation is required. When the adjusting handle is rotated to 20-30 degrees, the ventilation volume reaches its maximum, with an air volume of 400-600 cubic meters / hour, which can quickly reduce the humidity inside the water tank body 1 and effectively prevent bacterial growth and water quality deterioration.

[0049] By flexibly adjusting the angle of the regulating handle, users can precisely control the ventilation volume according to actual needs, ensuring a stable and suitable internal environment for the water tank body 1. The air is then filtered and discharged through the filter structure on top of the exhaust fan 11. By adjusting the angle of the regulating valve 7, ventilation needs in different usage scenarios can also be met, improving the practicality and flexibility of the water tank ventilation device. (In hot summer weather, to enhance the heat dissipation effect inside the water tank body 1, the regulating valve 7 can be adjusted to the maximum ventilation angle to maximize airflow; while in spring and autumn, the ventilation angle of the regulating valve 7 can be appropriately reduced to reduce noise.) When it is necessary to close the ventilation pipe 3, the body of the regulating valve 7 is rotated to the flat position. At this time, the sealing gaskets 15 at both ends of the regulating valve 7 will fit tightly, blocking the gap between the regulating valve 7 and the ventilation pipe 3.

[0050] Specifically: When the user needs to operate the water tank ventilation, firstly, by pulling the pin 9 upwards, it disengages from the toothed groove at the outer end of the regulating valve 7, releasing the limiting position of the regulating valve 7. At this time, the first spring 12 at the bottom of the pin 9 is compressed and stored. After the main body of the regulating valve 7 has adjusted the rotation angle, the pin 9 is released, the first spring 12 is released and rebounds, pushing the pin 9 to automatically return to its original position. At this time, the front end of the pin 9 is inserted into another toothed groove at the front end of the regulating valve 7 to limit and fix it (at this time, the new rotation angle is fixed), preventing the exhaust fan 11 from changing the rotation angle of the main body of the regulating valve 7, thus making it impossible to accurately control the ventilation volume. Moreover, when moving the pin 9, it slides on the inner wall of the first limiting groove 13 through the limiting blocks 14 on both sides, ensuring that the movement process is stable and will not fall out.

[0051] When the user finds that the filter pad 20 needs to be replaced after a long period of use, the sliding buckle 23 can be moved upward along the inner wall of the extension block 21. At this time, the clamping block 22 is no longer restricted and can be unfolded to both sides along the rotation axis, so that one end of it comes out of the groove at the front end of the bracket 19. Then the bracket 19 can be removed from the mounting groove 18, and the filter pad 20 can be replaced. During the replacement process, the sliding buckle 23 will squeeze the second spring 24, so that it stores force and compresses. After the installation is completed, the sliding buckle 23 is released, the second spring 24 is released and rebounds, and the clamping block 22 is restricted again to complete the fixation.

[0052] The above description is merely a preferred embodiment of the present utility model and does not constitute a limitation on the scope of protection of the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the scope of protection of the claims of the present utility model.
