Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, and in particular to a vacuum head and a pool cleaner. Background Technology

[0002] Swimming is a popular fitness and recreational activity that not only improves overall physical fitness but also enriches life. As people's living standards gradually improve, more and more family swimming pools are appearing in people's yards. The hygiene of these pools is crucial to swimmers' health, making regular cleaning an important task. However, given the large size and depth of swimming pools, manual cleaning is quite troublesome, leading to a growing demand for pool cleaning products.

[0003] In the existing technology, pool cleaners can be used to clean pools, which is labor-saving. However, pool cleaners usually use a water pump to extract dirt from the bottom of the pool, while the inlet of the suction head simultaneously sucks up dirt and water. This design can cause dirt to clog the inlet or enter the pool, affecting the stable operation of the water pump. Utility Model Content

[0004] One object of this application is to provide a suction head and pool cleaner that can prevent the inlet from becoming clogged.

[0005] The technical solution adopted in this application is as follows: a suction head, including a suction section and a conveying section, one end of the suction section extends into the conveying section, a water inlet channel is provided between the suction section and the conveying section, the other end of the suction section is provided with a suction port, the water inlet channel is connected to the conveying section, and the end of the conveying section away from the suction section is provided with a sewage outlet.

[0006] Compared with the prior art, the advantages of this application are that the suction section is used to suck up the sludge from the bottom of the pool, the conveying section is used to convey the sucked-up sludge, and the water inlet channel is used for liquid entry. The water inlet channel and the suction port are separated. Water enters through the water inlet channel to drive the water flow towards the sludge outlet, creating negative pressure in the suction port area to extract the sludge. The sludge will not enter the water inlet channel, thus preventing it from clogging the water inlet channel. The water inlet channel can be reduced in size to increase the flow rate. Since the sludge will not enter the water inlet channel, it will not come into contact with the water pump or other power components, ensuring reliable water intake.

[0007] In some embodiments of this application, the suction section is annular, and the cross-sectional area of ​​the suction section gradually decreases from bottom to top.

[0008] In some embodiments of this application, a portion of the suction section is inserted through the conveying section, and a gap is left between the suction section and the conveying section to form a water inlet channel; the water inlet channel is annular.

[0009] In some embodiments of this application, the outer surface of the suction section is provided with support ribs, which are in contact with the inner surface of the conveying section.

[0010] In some embodiments of this application, the conveying section includes a lower section and an upper section. The bottom end of the lower section is connected to the suction section, the top end of the upper section is connected to the sewage outlet, and the top end of the lower section is connected to the bottom end of the upper section. The cross-sectional area of ​​the lower section gradually decreases from bottom to top, and the cross-sectional area of ​​the upper section gradually increases from bottom to top.

[0011] In some embodiments of this application, the suction section and the conveying section are connected, and the water inlet channel is located on the suction section.

[0012] In some embodiments of this application, the suction section and the conveying section are connected by a connecting plate, and the water inlet channel is located on the connecting plate.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example 1:

[0023] This embodiment provides a suction head, such as Figure 1 , Figure 2As shown, it includes a suction section 1 and a conveying section 2. One end of the suction section 1 extends into the conveying section 2. A water inlet channel 3 is provided between the suction section 1 and the conveying section 2. The other end of the suction section 1 is provided with a suction port 4. The water inlet channel 3 is connected to the conveying section 2. The end of the conveying section 2 away from the suction section 1 is provided with a sewage outlet 5. The sewage outlet 4 and the sewage outlet 5 are connected. The water outlet direction of the water inlet channel 3 is towards the sewage outlet 5.

[0024] The suction section 1 is used to suck up sludge from the bottom of the pool, the conveying section 2 is used to convey the sucked-up sludge, and the water inlet channel 3 is used for liquid entry. The water inlet channel 3 and the suction port 4 are separated. Water enters through the water inlet channel 3 to drive the water flow towards the sludge outlet 5, creating negative pressure in the area of ​​the suction port 4 to extract sludge. Sludge will not enter the water inlet channel 3, thus preventing clogging of the water inlet channel 3. The water inlet channel 3 can be reduced in size to increase the flow rate. Sludge will not enter the water inlet channel 3 and will not come into contact with the water pump and other power components, ensuring reliable water intake.

[0025] To ensure the reliability of the suction section 1, the suction section 1 is annular, and its cross-sectional area gradually decreases from bottom to top. The bottom of the suction section 1 has a large cross-section, covering a large area, which facilitates the suction of dirt from the bottom of the pool. The upper cross-section is small, which increases the flow rate and facilitates the flushing of dirt to the outlet 5.

[0026] To ensure the reliability of the water inlet channel 3, part of the suction section 1 is inserted into the conveying section 2, and a gap is left between the suction section 1 and the conveying section 2 to form the water inlet channel 3; the water inlet channel 3 is annular, so that the water flow can move upward around the wall of the conveying section 2, and the suction force on the bottom is more balanced.

[0027] To ensure reliable suction, a support rib 6 is provided on the outer surface of the suction section 1, and the support rib 6 is in contact with the inner surface of the conveying section 2. When the suction head is working, it is prone to vibration. The support rib 6 can support the conveying section 2, ensure the stability of the water inlet channel 3, and prevent shaking that could cause changes in the water inlet channel 3. At the same time, the support rib 6 can strengthen the structural strength of the suction section 1.

[0028] To ensure the reliability of the conveying section 2, the conveying section 2 includes a lower section 7 and an upper section 8. The bottom end of the lower section 7 is connected to the suction section 1, and the top end of the upper section 8 is connected to the outlet 5. The top end of the lower section 7 is connected to the bottom end of the upper section 8. The cross-sectional area of ​​the lower section 7 gradually decreases from bottom to top. The bottom cross-section of the lower section 7 is large, covering a large area, which facilitates the suction of dirt from the bottom of the pool. It also facilitates cooperation with the suction section 1, forming a large water inlet channel 3 with a large water inlet area, ensuring the water flow has a driving effect on the dirt. The upper cross-section of the lower section 7 is small, which can increase the flow velocity and facilitate the dirt to be flushed to the outlet 5. The cross-sectional area of ​​the upper section 8 gradually increases from bottom to top. The gradually increasing cross-section of the upper section 8 facilitates the diffusion and discharge of dirt from the outlet 5, reducing dirt concentration and preventing dirt from clogging the outlet 5.

[0029] For ease of cleaning, the suction section 1 and the conveying section 2 are detachably connected. During use, the suction section 1 comes into frequent contact with dirt at the bottom of the pool, which can easily lead to dirt accumulation. The detachable design of the suction section 1 makes it easy to remove and clean it. At the same time, dirt can also easily accumulate between the suction section 1 and the conveying section 2, causing blockage of the water inlet channel 3. The detachable design of the suction section 1 also makes it easy to clean.

[0030] To ensure the reliability of the conveying section 2, a venturi tube is used in the conveying section 2.

One end of the suction section 1 extends into the conveying section 2. A water inlet channel 3 is provided between the suction section 1 and the conveying section 2. The other end of the suction section 1 is provided with a suction port 4. The water inlet channel 3 is connected to the conveying section 2. The end of the conveying section 2 away from the suction section 1 is provided with a sewage outlet 5.

[0033] To improve structural strength, the suction section 1 and the conveying section 2 are integrated and connected, with the water inlet channel 3 located on the suction section 1.

[0034] All other features are the same as in Example 1.
