Description

Technical Field

[0001] The utility model relates to the field of filter elements, in particular to a filter element foaming structure and a shower head thereof. Background Art

[0002] Shower heads are commonly used in bathrooms for showering. Since the water used in bathrooms is generally hot water and cold water, showering is mainly achieved by mixing hot water and cold water into a water flow of appropriate temperature for flushing. Existing shower heads are generally equipped with filters and aerators in the shower head without affecting the hand-held effect, so as to improve the quality of the water flow and the flushing effect of the water. In order to improve the functionality of the water flow, some shower heads are also equipped with fragrance boxes. When the water is discharged, the fragrance in the fragrance box will be released with the water flow, so that the water flow during showering is mixed with fragrance.

[0003] Since the water from the shower head needs to flow through the fragrance box before being output, the fragrance box is set on the flow trajectory of the water flow, which will have a certain impact on the normal flow of the water flow, thereby reducing the shower effect of the shower head.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0031] See also Figure 1-Figure 7The present embodiment provides a shower head, comprising a shell 1 and a filter element 2. The shell 1 is provided with a liquid inlet chamber 11 and a liquid outlet chamber 12 that are connected to each other. The liquid inlet chamber 11 is provided with a liquid inlet 13, the liquid outlet chamber 12 is provided with a liquid outlet 14, and a filter screen 15 is provided on the liquid outlet 14. The filter element 2 is located in the liquid inlet chamber 11.

[0032] In which, the filter element 2 includes a filter element 3 and a bubble element 4 for forming micro-bubble water. A liquid flow channel 51 is opened on the top surface of the filter element 3 along its axial direction, and a filter cavity 52 for accommodating large-particle filter materials is opened on the bottom end of the filter element 3. The filter cavity 52 is connected to the liquid flow channel 51 and its inlet is located in the flow direction of the water flow. The filter element 3 and the bubble element 4 are arranged in sequence along the flow direction of the water flow. There is a gap space 53 between the filter element 3 and the bubble element 4, and the two are connected by a number of connecting pieces 6.

[0033] During use, the water flow entering the liquid inlet chamber 11 of the shower head is first filtered by the filter element 3 during the process of flowing through the filter element 2. Then the bubbling element 4 processes the flowing water into micro-bubble water and enters the liquid outlet chamber 12. The filter mesh 15 cuts the bubbles in the water flow to form smaller micro-bubbles for water discharge, thereby improving the effect of the shower head water discharge.

[0034] See also Figure 2 The liquid inlet cavity 11 is cylindrical and the liquid outlet cavity 12 is annular, which ensures the installation of the filter element 2 in the shower head and the spraying range when the water is used.

[0035] See also Figure 3 、 Figure 4 The filter element 3 comprises a first body 31 and a first cover 32. A liquid flow channel 51 is defined on the top surface of the first body 31. The first cover 32 is detachably mounted on the bottom end of the first body 31, and the two enclose a filter chamber 52. The filter chamber 52 is disposed around the liquid flow channel 51. The first cover 32 is provided with a first liquid inlet 33 in communication with the filter chamber 52. The assembled structure of the filter element 3 reduces the difficulty in manufacturing the filter chamber 52 of the filter element 3. Furthermore, since the components of the filter element 3 can be manufactured separately, manufacturing losses are reduced.

[0036] During use, water flows into the filter chamber 52 through the first liquid inlet 33, and is filtered by the large particle filter material in the filter chamber 52, and then flows into the gap space 53 and the liquid inlet chamber 11 in sequence through the liquid flow channel 51, completing the filtering effect of the water flow.

[0037] In this embodiment, the first cover 32 and the first body 31 are connected via a snap-fit ​​structure.

[0038] See also Figure 4 、 Figure 5A second cover 34 is detachably mounted on the top of the first body 31, and a receiving cavity 35 for receiving fragrance particles is formed between the two, which reduces the difficulty of manufacturing the receiving cavity 35 on the first body 31. The receiving cavity 35 is arranged around the liquid flow channel 51, and a through hole 36 is opened on the second cover 34. The receiving cavity 35 and the gap space 53 are connected through the through hole 36.

[0039] During use, as the water flowing out of the liquid flow channel 51 flows into the liquid inlet chamber 11 through the gap space 53, the fragrance liquid in the accommodating chamber 35 can enter the gap space 53 through the through hole 36 and mix into the water flow, thereby improving the water flow effect while also reducing the odor in the bathroom to a certain extent, ensuring the freshness of the shower environment and enhancing the shower experience.

[0040] In this embodiment, the second cover 34 and the first body 31 are connected via a snap-fit ​​structure.

[0041] See also Figure 4 、 Figure 6 The foaming member 4 includes a second main body 41 and a third cover 42. The second main body 41 is a hollow structure with openings at both ends. A mixing seat 43 is provided in the cavity at the top of the second main body 41. A plurality of mixing channels 44 are provided on the mixing seat 43 along its axial direction. The openings at both ends of the second main body 41 are connected through the mixing channels 44. The third cover 42 is sleeved and fixed on the bottom end of the second main body 41. A plurality of second liquid inlets 45 arranged at equal angles around the axis thereof are provided on the side surface of the second main body 41.

[0042] Among them, the mixing channel 44 includes a first channel 46, a second channel 47 and a third channel 48 which are connected in sequence along the direction of water flow. The first channel 46 is truncated cone-shaped, the second channel 47 is cylindrical, and the third channel 48 is inverted truncated cone-shaped. The length of the first channel 46 is greater than the length of the second channel 47 and less than the length of the third channel 48.

[0043] During use, the water mixed with air in the liquid inlet chamber 11 enters the cavity of the second main body 41 from the second liquid inlet 45 and flows along the mixing channel 44. The mixing channel 44 guides and converges the water flowing through, so that its flow rate is accelerated and the air contained therein is also gathered. The converged water flow is then diffused and ejected, so that the water flow and air are mixed again to form micro-bubble water, thereby ensuring the uniformity of the air mixing in the water flow. The mixed water flow is then cut by the filter 15, so that the bubbles in the water flow are cut into smaller micro-bubbles, thereby achieving the effect of bubbling water out of the shower head.

[0044] In this embodiment, the third cover 42 and the second body 41 are connected via a snap-fit ​​structure.

[0045] In order to ensure the sealing of the mixing seat 43 installed in the second body 41 and reduce the risk of liquid leakage due to the gap between the mixing seat 43 and the second body 41, a sealing ring 7 is sandwiched between the mixing seat 43 and the sealing ring 7, and the sealing ring 7 is embedded in the mixing seat 43.

[0046] See also Figure 4 The third cover 42 is integrally connected to a cylindrical flow guide 8. This flow guide 8 is located within the cavity at the bottom of the second body 41, with a flow guide space 81 between them. The top edge of the flow guide 8 is provided with a plurality of communication ports 82 arranged at equal angles around the central axis of the flow guide 8. The length of the communication ports 82 is shorter than that of the second liquid inlet 45. The provision of the flow guide space 81 and the structural arrangement of the flow guide 8 ensure that the water filtered by the filter element 3 is mixed with the fragrance liquid while also guiding the water into the mixing channel 44 of the mixing seat 43, thereby ensuring the effectiveness of the filter element 2.

[0047] See also Figure 6 The second main body 41 is provided with a filter sleeve 9 to filter the water entering the bubbler 4 again, thereby ensuring the use effect of the shower head.
