In practical applications, after entering the water inlet cavity 111, external water enters the water outlet channel 113 through the water inlet 1131 of the water outlet channel 113, and then exits the water outlet channel 113 through the channel water outlet 1133, in this embodiment, the water exiting the water outlet channel 113 is directly conveyed to the spray head 213 through a pipeline.
An installation cylinder 115 is arranged in the water inlet cavity 111, and in this embodiment, the installation cylinder 115, the water inlet cavity 111 and the water outlet channel 113 are all coaxially arranged. The elastic member 150 is a spring, and is disposed in the installation cylinder 115, and one end of the installation cylinder 115, which is far away from the water inlet 1131, is directly communicated with the outside atmosphere.
Referring to fig. 2 and 4, the balance valve core 130 includes a balance shaft 131 and a switching tooth 133, and in this embodiment, the balance shaft 131 and the switching tooth 133 are not rigidly connected. In other embodiments, the balance shaft 131 and the switching teeth 133 may be connected as a whole according to the actual application. The balance valve core 130 is provided with a first end 1311 and a second end 1313, which are two ends of the balance shaft 131 in this embodiment. The first end 1311 is inserted into the mounting tube 115, the end wall of the first end 1311 abuts against the elastic member 150, i.e., the spring, the second end 1313 is inserted into the water outlet channel 113, the end wall of the second end 1313 abuts against the switching tooth 133, the switching tooth 133 selectively cooperates with the housing 110 at the end of the water outlet channel 113 away from the water inlet cavity 111, and the switching tooth 133 and the housing 110 are driven to switch the cooperating state through an external force, so that the balance shaft 131 is driven to act, and the switching between the water stopping state and the water passing state of the shower water stopping structure 100 is realized.
A first ring wall 1315 is convexly arranged on the side wall of the first end 1311, the first ring wall 1315 is attached to the inner side wall of the installation barrel 115, a second ring wall 1317 is convexly arranged on the side wall of the second end 1313, the second ring wall 1317 is attached to the inner side wall of the water outlet channel 113, a third ring wall 1319 is convexly arranged on the side wall between the first ring wall 1315 and the second ring wall 1317, and the third ring wall 1319 is accommodated in the water inlet cavity 111 and is used for selectively closing the water inlet 1131 under the driving of the balance valve element 130. In this embodiment, the first, second and third walls 1315, 1317, 1319 are all sleeved with a sealing ring.
Fig. 2 is a schematic view of the internal structure of the sprinkler sealing structure 100 in a sealing state, in which the switching tooth 133 is in sealing engagement with the housing 110. At this time, the third ring wall 1319 is pressed against the side wall of the water inlet 1131 opened in the water inlet cavity 111 under the action of the elastic member 150, so as to seal the water inlet 1131. The axial cross-sectional areas of the first and third walls 1315 and 1319 are almost equal, i.e. in practice, the static water pressures to which the first and third walls 1315 and 1319 are subjected are almost equal. At this time, an external force is applied to the switching teeth 133 to switch the switching teeth from water-stopping matching to water-passing matching with the housing 110, so as to drive the balance shaft 131 to move axially close to the mounting cylinder 115, so that when the water inlet 1131 is opened, the external force overcomes only the elastic force of the elastic member 150, i.e., the spring, and the water pressure is balanced by the first and third walls 1315 and 1319.
Fig. 3 is a schematic view illustrating an internal structure of the shower water stopping structure 100 in a water flowing state, in which the switching teeth 133 are in water flowing engagement with the housing 110. At this time, a gap exists between the third ring wall 1319 and the side wall of the water inlet cavity 111, which is provided with the water inlet 1131, the water inlet 1131 is opened, and the water inlet cavity 111 is communicated with the water outlet channel 113. The axial cross-sectional areas of the first and second walls 1315, 1317 are almost equal, i.e. in practice, the dynamic water pressures to which the first and second walls 1315, 1317 are subjected are almost equal. At this time, an external force is applied to the switching teeth 133 to switch the switching teeth from water-passing matching to water-stopping matching with the housing 110, so as to drive the balance shaft 131 to move axially, so that the third ring wall 1319 is pressed against the side wall of the water inlet cavity 111 where the water inlet 1131 is opened under the action of the elastic member 150, so that in the process of closing the water inlet 1131, the external force overcomes only the elastic force of the elastic member 150, i.e., the spring, and the dynamic water pressure is balanced by the first ring wall 1315 and the second ring wall 1317.
In order to prevent the pressure holding and vacuum pumping phenomena during the axial movement of the balance shaft 131, in this embodiment, the side of the first ring wall 1315 away from the second end 1313 is isolated from the water inlet chamber 111 and is communicated with the atmosphere, and the side of the second ring wall 1317 away from the first end 1311 is isolated from the water outlet channel 113 and is communicated with the atmosphere.
As shown in fig. 4 and fig. 5, a plurality of first helical teeth 1331 and a plurality of limiting ribs 1333 are respectively protruded from an end surface of the switching tooth 133 at an end away from the balance shaft 131, the plurality of first helical teeth 1331 are circumferentially distributed at intervals, and the protruded height of the first helical teeth 1331 is higher than the protruded height of the limiting ribs 1333. In this embodiment, the number of the first helical teeth 1331 is four, the inclined directions of the inclined surfaces of the first helical teeth 1331 are the same, and the number of the limiting ribs 1333 is two, and the limiting ribs are symmetrically arranged.
Please refer to fig. 5 and fig. 6, a matching cavity 1135 and a plurality of matching grooves 1137 are respectively recessed on an end wall of one end of the water outlet channel 113 away from the water inlet cavity 111, the matching grooves 1137 are symmetrically distributed along the periphery of the matching cavity 1135, a plurality of second helical teeth 1139 are protruded from the bottom of the matching cavity 1135, and the second helical teeth 1139 are circumferentially distributed at intervals. In this embodiment, the second helical teeth 1139 correspond to the first helical teeth 1331, are four in number and are correspondingly circumferentially spaced apart, and the mating grooves 1137 are two in number and are correspondingly symmetrically distributed.
When the switching teeth 133 and the housing 110 are in water-stop fit as shown in fig. 2, the first inclined teeth 1331 and the second inclined teeth 1139 are in cross fit, and the limiting rib 1333 is inserted into the fitting groove 1137, at this time, under the action of the elastic member 150, the third ring wall 1319 closes the water inlet 1131.
When the switching teeth 133 and the housing 110 are in the water-through fit as shown in fig. 3, the plurality of first inclined teeth 1331 and the plurality of second inclined teeth 1139 are in cross fit, and the limiting rib 1333 abuts against the end wall of the end of the water outlet channel 113 far away from the water inlet cavity 111. At this time, since the limiting ribs 1333 are not inserted into the matching grooves 1137 but abut against the end walls of the recessed matching grooves 1137, a gap exists between the third ring wall 1319 and the end wall provided with the water inlet 1131, that is, the water inlet cavity 111 is communicated with the water outlet channel 113.
Referring to fig. 1 to 7, one end of the push rod 170 contacts the button 2111, and the other end thereof is provided with a plurality of ribs 171 and inserted into the matching cavity 1135 from the bottom of the matching cavity 1135 far away from the water inlet cavity 111. The number of the ribs 171 is four corresponding to the first helical teeth 1331 and the second helical teeth 1139, and the four ribs 171 are respectively accommodated in four gaps generated between every two of the four second helical teeth 1139.
In practical applications, if the sprinkler water stopping structure 100 is in the water stopping state as shown in fig. 2, the switching teeth 133 are in water stopping fit with the housing. At this time, the operator presses the button 2111, and the button 2111 pushes the push rod 170 to move along the axial direction of the water outlet channel 113, so that the four ribs 171 respectively and correspondingly abut against the slopes of the four first inclined teeth 1331, and further pushes the four first inclined teeth 1331 to gradually exit from the gaps between the second inclined teeth 1139 along the axial direction, in the process, the elastic member 150 is gradually compressed, and before the first inclined teeth 1331 completely exit from the gaps between the second inclined teeth 1139, the limit ribs 1333 completely exit from the mating grooves 1137. When the four first helical teeth 1331 just completely exit the gaps between the second helical teeth 1139, the first helical teeth 1331 are no longer limited by the side walls of the second helical teeth 1139, and the inclined surfaces of the first helical teeth 1331 slide relative to the rib 171, that is, the switching teeth 133 rotate until the inclined surfaces of the first helical teeth 1331 abut against and abut against the inclined surfaces of the second helical teeth 1139. At this time, the external force is removed, the elastic member 150 reversely pushes the balance shaft 131, and under the pushing of the balance shaft 131, the respective attached slopes of the first sloped teeth 1331 and the second sloped teeth 1139 on the switching tooth 133 slide relatively, and the switching tooth 133 further rotates until the four first sloped teeth 1331 respectively and correspondingly fall into the adjacent gap surrounded by the four second sloped teeth 1139. The two limiting ribs 1333 abut against the end wall of the water outlet channel 113 at the end far from the water inlet cavity 111, and a gap is formed between the third ring wall 1319 and the wall surface provided with the water inlet 1131, that is, the water stop structure of the shower head is switched to the water passing state shown in fig. 3.
If the shower water stopping structure 100 is in the water passing state as shown in fig. 3, the switching teeth 133 are in water passing fit with the housing. At this time, the operator presses the button 2111, and the button 2111 pushes the push rod 170 to move along the axial direction of the water outlet channel 113, so that the four ribs 171 respectively and correspondingly abut against the respective slopes of the four first inclined teeth 1331, and further pushes the four first inclined teeth 1331 to gradually exit from the gaps between the second inclined teeth 1139 along the axial direction, and the elastic member 150 is gradually compressed in the process. When the four first helical teeth 1331 just completely exit the gaps between the second helical teeth 1139, the first helical teeth 1331 are no longer limited by the side walls of the second helical teeth 1139, and the inclined surfaces of the first helical teeth 1331 slide relative to the rib 171, that is, the switching teeth 133 rotate until the inclined surfaces of the first helical teeth 1331 abut against and abut against the inclined surfaces of the second helical teeth 1139. At this time, the external force is removed, the elastic member 150 reversely pushes the balance shaft 131, and under the pushing of the balance shaft 131, the respective attached slopes of the first sloped teeth 1331 and the second sloped teeth 1139 on the switching tooth 133 slide relatively, and the switching tooth 133 further rotates until the four first sloped teeth 1331 respectively and correspondingly fall into the adjacent gap surrounded by the four second sloped teeth 1139. The two limiting ribs 1333 are inserted into the two matching grooves 1137, the third ring wall 1319 is attached to the wall surface provided with the water inlet 1131, and the water inlet 1131 is sealed, that is, the water stopping structure of the shower head is switched to the water stopping state shown in fig. 2.
When the water-stopping state is switched to the water-passing state, the first ring wall 1315 balances the static water pressure on the third ring wall 1319, so that the process of pressing the button 2111 by external force only needs to overcome the elasticity of the elastic element 150. When the water-passing state is switched to the water-stopping state, the first ring wall 1315 balances the dynamic water pressure on the second ring wall 1317, so that the process of pressing the button 2111 by external force only needs to overcome the elastic force of the elastic element 150. Therefore, in this embodiment, the shower water stopping structure 100 has the function of balancing the water pressure, and realizes the easy switching between the water stopping state and the water passing state.
Therefore, the shower head assembly 200 provided by the embodiment is convenient to operate and better in user experience.
