Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and in particular to a protective component and a shower device. Background Technology

[0002] Showerheads, faucets, and other water outlet modules have a certain pressure limit. When the water outlet module is clogged or malfunctions, the water flow decreases, while the internal water pressure increases, making the module prone to bursting. Existing technology includes protective components to prevent water outlet modules from bursting due to high pressure. These components are typically installed upstream of the water outlet module. When the internal water pressure rises to a certain level, the valve core of the protective component moves accordingly, allowing water to flow out from the pressure relief hole, thus slowing the rate of pressure increase and preventing bursting. However, the water ejected from the pressure relief hole can spray into the surrounding environment, potentially wetting items or body parts that shouldn't be wet, causing inconvenience to the user.

[0006] The protective component according to the first aspect of this utility model has at least the following beneficial effects: The protective component increases the area blocked by the first water outlet by the movement of the piston when the water pressure rises, thereby reducing the flow rate of the first water outlet and thus reducing the water flowing downstream to the water outlet module, lowering the risk of the downstream water outlet module bursting. After the water pressure drops, the elastic element drives the piston to reset, gradually restoring the water output of the downstream water outlet module.

[0030] Figure 1 A protective assembly 101 according to an embodiment of the present invention is shown. The protective assembly 101 includes a housing 102, a piston 112, and an elastic member 116. The housing 102 has a flow channel 120, which includes an inlet 119, a first through-hole 118, and an outlet 109, wherein the first through-hole 118 is located between the inlet 119 and the outlet 109. Figure 3 As shown, the outer casing 102 may include a main body 104, a side plug 103, a slag discharge plug 105, and a bottom cover 108. The side plug 103, slag discharge plug 105, and bottom cover 108 are all detachably connected to the main body 104. More specifically, the side plug 103, slag discharge plug 105, and bottom cover 108 are all fixed to the main body 104 by threaded connections. A water inlet 119 is located at the top of the main body 104, the bottom cover 108 is connected to the bottom of the main body 104, the water outlet 109 is located at the bottom of the bottom cover 108, and the first water passage 118 is located inside the main body 104.

[0031] Piston 112 is located inside housing 102, and piston 112 is movably connected to housing 102. For example, as Figure 3 As shown, the main body 104 of the outer casing 102 is provided with an installation channel 137, which is located below the first water inlet 118. The piston 112 is slidably disposed in the installation channel 137. The piston 112 can contact the water inside the outer casing 102. The piston 112 can move relative to the outer casing 102 in a first direction due to the increase in water pressure in the flow channel 120, thereby increasing the area of ​​the first water inlet 118 blocked by the piston 112. An elastic member 116 is connected to the piston 112. The elastic member 116 can drive the piston 112 to move relative to the outer casing 102 in a second direction due to the decrease in water pressure in the flow channel 120, thereby reducing the area of ​​the first water inlet 118 blocked by the piston 112.

[0032] The first direction and the second direction are opposite, for example, in Figure 1 and Figure 2 In the diagram, the first direction is from left to right, and the second direction is from right to left. If we consider... Figure 1 Given the initial state, after piston 112 moves along the first direction, the position of piston 112 can be as follows: Figure 2 As shown. In this utility model, the area of ​​the first water inlet 118 blocked by the piston 112 specifically refers to the area of ​​the first water inlet 118 blocked by the piston 112 when viewed along the axial direction of the first water inlet 118 (e.g., viewed from top to bottom). Figure 1 In the middle, the first water passage 118 is not blocked by the piston 112 at all, and the area of ​​the first water passage 118 blocked by the piston 112 is the smallest, or in other words, the area of ​​the first water passage 118 not blocked by the piston 112 is the largest. Figure 2In the middle, only the right end of the first water inlet 118 is not blocked by the piston 112. The area of ​​the first water inlet 118 blocked by the piston 112 is the largest, or in other words, the area of ​​the first water inlet 118 not blocked by the piston 112 is the smallest.

[0033] Figure 1 and Figure 2 The dashed lines with arrows indicate the water flow path. Water entering the outer casing 102 from the inlet 119 will subsequently flow through the first outlet 118 and the outlet 109 in sequence. Figure 1 and Figure 2 In the indicated state, water can flow from outlet 109. However, the smaller the area of ​​the first water inlet 118 blocked by piston 112, the greater the flow rate at the first water inlet 118, the greater the flow rate at outlet 109, and the greater the flow rate of the water outlet module downstream of the protective component 101. Conversely, the larger the area of ​​the first water inlet 118 blocked by piston 112, the smaller the flow rate at outlet 109, and the smaller the flow rate of the water outlet module downstream of the protective component 101. The water outlet module is not in... Figure 1 and Figure 2 As shown, the water outlet module can be a shower head, faucet, spray gun, etc.

[0034] Assuming the water outlet module becomes clogged and the water flow decreases, the internal water pressure of the water outlet module will rise because water continues to flow from upstream. This increase in internal water pressure will also increase the water pressure in the upstream protective component 101. During this pressure increase in the flow channel 120 of the protective component 101, the water pressure overcomes the elastic force of the elastic element 116 and drives the piston 112 to gradually move in the first direction. This results in an increase in the area blocked by the piston 112 at the first water outlet 118, reducing the flow rate at the outlet 109 of the protective component 101. Because the flow rate at the outlet 109 of the protective component 101 decreases, less water enters the downstream water outlet module, slowing down the rate of increase in internal water pressure and even causing a decrease in water pressure. This helps reduce the risk of the water outlet module bursting.

[0035] After the blockage problem in the water outlet module is resolved, the water pressure in the water outlet module gradually decreases, and correspondingly, the water pressure inside the protective component 101 also gradually decreases. During the process of water pressure decrease in the flow channel 120 of the protective component 101, the elastic force of the elastic element 116 overcomes the water pressure and drives the piston 112 to gradually move in the second direction, thereby reducing the area blocked by the piston 112 in the first water outlet 118, increasing the flow rate at the water outlet 109 of the protective component 101, and thus gradually restoring the normal water output of the water outlet module.

[0036] The protective component 101 of this invention increases the area blocked by the first water outlet 118 when the water pressure rises due to the movement of the piston 112, thereby reducing the flow rate of the first water outlet 118 and thus reducing the water flowing downstream to the water outlet module through the outlet 109, reducing the risk of the downstream water outlet module bursting. After the water pressure drops, the elastic element 116 drives the piston 112 to reset, thereby gradually restoring the water output of the downstream water outlet module. Furthermore, the protective component 101 achieves the explosion-proof function of the water outlet module by reducing the water flow rate of the outlet 109. The protective component 101 does not require a pressure relief hole on its outer casing 102, and will not spray water into the surrounding environment through the pressure relief hole during operation.

[0037] It should be noted that, in Figure 2 In the illustrated embodiment, when the area of ​​the first water outlet 118 blocked by the piston 112 is at its maximum, the first water outlet 118 is not completely blocked and sealed by the piston 112. In other embodiments not shown, when the area of ​​the first water outlet 118 blocked by the piston 112 is at its maximum, the first water outlet 118 can also be completely blocked and sealed by the piston 112. To reduce the amount of water flowing to the downstream outlet module, it is sufficient that the movement of the piston 112 in the first direction can increase the area of ​​the first water outlet 118 blocked by the piston 112.

[0038] As described above, piston 112 can be driven by water pressure to move in the first direction. The shape of flow channel 120 and the arrangement of piston 112 will be described below to explain why piston 112 is driven by water pressure to move in the first direction.

[0039] like Figure 3 As shown, the flow channel 120 includes a first branch 121 and a second branch 122. The first branch 121 includes an inlet 119, a first outlet 118, and an outlet 109, and the first branch 121 intersects with the installation channel 137. After the piston 112 is installed in the installation channel 137, a portion of the piston 112 will be located below the first outlet 118. The inlet 124 of the second branch 122 communicates with the first branch 121, and along the flow path of water in the first branch 121, the inlet 124 is located between the inlet 119 and the first outlet 118. To facilitate understanding of "the inlet 124 is located between the inlet 119 and the first outlet 118", it can be combined with... Figure 4 First, understand the shapes of the first branch 121 and the second branch 122. Figure 3 Implementation examples and Figure 4 The main difference in the embodiments lies in the shape of the filter 123 (this difference will be described in detail below), but Figure 3 The shapes of the first branch 121 and the second branch 122 in the middle are similar to Figure 4The first branch 121 and the second branch 122 have essentially the same shape. The first branch 121 is vertical, with the inlet 119 located at the top and the outlet 109 located at the bottom. Water flows from top to bottom in the first branch 121. The inlet 124 of the second branch 122 is located below the inlet 119 and above the first outlet 118. The outlet 125 of the second branch 122 is closed; for example, a slag plug 105 is provided at the outlet 125 to prevent water from flowing out of the outlet 125 of the second branch 122.

[0040] Please combine Figures 1 to 3 One end of the piston 112 is located within the second branch 122, allowing water within the second branch 122 to contact the piston 112. The piston 112 also includes a second water inlet 111, which communicates with the first water inlet 118. Figure 2 As shown, the first water inlet 118 is connected to the second water inlet 111 only through its right end, and the area where the first water inlet 118 connects to the second water inlet 111 is relatively small. Figure 1 As shown, the first water inlet 118 is entirely connected to the second water inlet 111, and the area where the first water inlet 118 connects to the second water inlet 111 is relatively large. In this invention, the area where the first water inlet 118 connects to the second water inlet 112 is actually equivalent to the area of ​​the first water inlet 118 not obstructed by the piston 112 when viewed along the axial direction of the first water inlet 118 (e.g., viewed from top to bottom). Therefore, when the piston 112 moves along the first direction, the area of ​​the first water inlet 118 obstructed by the piston 112 gradually increases, and the area where the first water inlet 118 connects to the second water inlet 111 gradually decreases. When the piston 112 moves along the second direction, the area of ​​the first water inlet 118 obstructed by the piston 112 gradually decreases, and the area where the first water inlet 118 connects to the second water inlet 111 gradually increases.

[0041] When the interior of the outer casing 102 is filled with water, the water in the second water inlet 111 will exert pressure on the piston 112, and the water in the second branch 122 will also exert pressure on the left end of the piston 112. For example... Figure 1 As shown, the water in the second inlet 111 exerts pressure on the left and right walls of the second inlet 111 respectively. Since the areas of these two walls are the same, the two pressures can be considered to cancel each other out. After the water pressure rises to a sufficiently high level, the pressure exerted by the water in the second branch 122 on the left end of the piston 112 overcomes the elastic force of the elastic element 116, thereby pushing the piston 112 to move in the first direction (to the right).

[0042] In some other embodiments not shown, the end of the piston 112 may not be located in the second branch 122 in order for the water pressure to push the piston 112 to move in the first direction. For example, the mounting channel 137 is completely separated from the second branch 122, and the left end of the piston 112 does not contact the water in the second branch 122; correspondingly, the area of ​​the right side wall of the second water outlet 111 can be larger than the area of ​​the left side wall of the second water outlet 111, so that the pressure exerted by the water in the second water outlet 111 on the right side wall is greater than the pressure exerted on the left side wall, and the water in the second water outlet 111 will push the piston 112 to the right (moving in the first direction).

[0043] like Figure 1 As shown, the end of piston 112 away from the second branch 122, together with the inner wall of mounting channel 137, defines an active space 117. Flow channel 120 and second water inlet 111 are both separated from the active space 117. More specifically, piston 112 includes a first sealing ring 113. The outer periphery of the first sealing ring 113 abuts against the inner wall of mounting channel 137. The first sealing ring 113 is located between the second water inlet 111 and the elastic member 116, thereby separating flow channel 120 and second water inlet 111 from the active space 117. The elastic member 116 is located within the active space 117. It should be noted that regardless of the position of piston 112, flow channel 120 and second water inlet 111 are separated from the active space 117. Housing 102 also has a pressure balancing hole 114. One end of pressure balancing hole 114 communicates with the active space 117, and the other end of pressure balancing hole 114 protrudes from the outer surface of housing 102.

[0044] Since both the flow channel 120 and the second water outlet 111 are separated from the active space 117, water will not enter the active space 117, nor will water flow out from the pressure balance hole 114, thus preventing the pressure balance hole 114 from becoming a pressure relief hole for water. The active space 117 can be considered as part of the installation channel 137, and the size of the active space 117 changes with the movement of the piston 112. The pressure balance hole 114 is used to connect the external environment with the active space 117. Even if the active space 117 changes, the external environment and the active space 117 can still maintain pressure balance, thereby ensuring that the first piston 112 can move smoothly.

[0045] like Figure 3 and Figure 4 As shown, in some embodiments, the protective component 101 further includes a filter 123, which can filter out impurities (such as scale) from upstream of the protective component 101, thereby reducing the risk of the water outlet module located downstream of the protective component 101 being blocked by impurities.

[0046] After prolonged use, a large amount of impurities will accumulate on the filter screen 123 of the protective component 101. If the filter screen 123 is not cleaned in time, the protective component 101 itself will become clogged; or the filtration effect of the filter screen 123 will decrease, increasing the risk of clogging of the water outlet module. To facilitate the cleaning of impurities, in some embodiments, at least a portion of the filter screen 123 is located within the first branch 121, and the filter screen 123 is adjacent to the inlet 124 of the second branch 122. The filter screen 123 is inclined or bent so that the water flow guides the impurities on the filter screen 123 to the second branch 122.

[0047] like Figure 3 or Figure 4 As shown, since the flow channel 120 includes a first branch 121 and a second branch 122, a portion of the water entering the housing 102 flows along the first branch 121, while the remaining water enters the second branch 122. Because the filter screen 123 is inclined or bent, when water flows over its surface, it washes away impurities, pushing at least some of these impurities towards the inlet 124 of the second branch 122, allowing them to enter the second branch 122. When a significant amount of impurities accumulates in the second branch 122, the user can remove the slag drain plug 105 to clean the impurities inside the second branch 122.

[0048] The specific shapes of filters 1, 2, and 3 are described below. Figure 3 As shown, in one embodiment, the filter 123 is an upwardly convex hemispherical shape, and at least a portion of the filter 123 is higher than the lowest point of the inlet 124. The lowest point of the inlet 124 is... Figure 3 Point A in the diagram. As water flows through the spherical surface of filter screen 123, it gradually diffuses along the surface. Impurities on filter screen 123 flow downwards along the spherical surface with the water and then enter the second branch 122 from inlet 124. To facilitate the entry of scale and impurities into the second branch 122, the curved filter screen 123 does not necessarily need to be spherical or hemispherical. In some embodiments not shown, it is sufficient that the water flows towards inlet 124 as it flows down the curved filter screen 123.

[0049] like Figure 4 As shown, in another embodiment, to facilitate the entry of scale and impurities into the second branch 122, the filter screen 123 can also be planar and inclined relative to the horizontal plane, with its bottom end connected to the lowest point of the inlet 124. In this configuration, impurities on the filter screen 123 will flow along the inclined surface of the filter screen 123 with the water flow and then enter the second branch 122 from the inlet 124.

[0050] like Figure 4As shown, the second branch 122 includes an inclined section 139 and a slag storage section 140. The inclined section 139 is inclined relative to the horizontal plane, and its top end is the inlet 124 of the second branch 122. The slag storage section 140 is vertically arranged, with its top end connected to the bottom end of the inclined section 139. The bottom end of the slag storage section 140 is the outlet 125, and the slag discharge plug 105 is located at the bottom end of the slag storage section 140. The inclined section 139 facilitates the entry of impurities into the depth of the second branch 122, and the vertical inclined section 139 facilitates the deposition of impurities on the slag discharge plug 105, thereby facilitating subsequent cleaning of impurities by the user.

[0051] like Figure 1 and 2 As shown, the end of piston 112 can extend into slag storage section 140. (As indicated...) Figure 1 As shown, the piston 112 also includes a second sealing ring 106, which is located between the left end of the piston 112 and the second water inlet 111. The second sealing ring 106 can prevent water in the slag storage section 140 from leaking into the first branch 121, thereby preventing impurities in the slag storage section 140 from flowing to the first branch 121 with the water flow, and thus preventing impurities from flowing to the downstream water outlet module through the water outlet 109.

[0052] like Figure 1 As shown, the protective assembly 101 also includes a descaling module 107, which is located within the flow channel 120 and between the piston 112 and the outlet 109. More specifically, the first branch 121 includes a mounting section located downstream of the first inlet 118 and upstream of the outlet 109, with the descaling module 107 located within the mounting section. A bottom cover 108 supports the descaling module 107 to prevent it from falling off. The descaling module 107 includes a descaling agent 110, and its surface has through holes allowing water to enter and exit, contacting the descaling agent 110. The descaling agent 110 can also be slowly released into the water outside the descaling module 107. The descaling module 107 reduces scale buildup, thereby reducing the risk of the outlet module downstream of the protective assembly 101 being clogged by scale. The specific composition of the descaling agent 110 is prior art and will not be described in detail here.

[0053] like Figure 2 As shown, the protective component 101 also includes a reminder module 115, which is connected to the housing 102. When the area of ​​the first water outlet 118 blocked by the piston 112 is at its maximum, the piston 112 abuts against the reminder module 115, and the portion of the reminder module 115 exposed outside the housing 102 emits light or the reminder module 115 emits sound. When the area of ​​the first water outlet 118 blocked by the piston 112 is at its maximum, the water outlet module may become blocked, and the light or sound emitted by the reminder module 115 can remind the user to troubleshoot the water outlet module in a timely manner.

[0054] Please combine Figure 2 and Figure 5 The reminder module 115 includes a mounting base 130, a circuit board 131, a battery 129, a working element 128, a conductive spring 127, and a trigger element 126. The mounting base 130 is fixedly connected to the housing 102. More specifically, the mounting base 130 includes a first seat body 134, a pressure cap 135, and a second seat body 136, both of which are annular (e.g., ...). Figure 5 (As shown). Please refer to... Figure 2 and Figure 5 The first seat 134 is fixedly connected to the main body 104 of the outer casing 102. The first seat 134 is fitted over the second seat 136, and the first seat 134 and the second seat 136 are fixedly connected. The second seat 136 is fitted over the pressure cover 135, and the second seat 136 is fixedly connected to the pressure cover 135. The circuit board 131, the battery 129, and the conductive spring 127 are all installed inside the fixing seat 130. More specifically, the circuit board 131, the battery 129, and the conductive spring 127 can all be located in the cavity enclosed by the pressure cover 135 and the second seat 136. The first end of the battery 129, the circuit board 131, and the conductive spring 127 are all electrically connected to the circuit board 131, and the second end of the conductive spring 127 can move relative to the circuit board 131. Figure 2 and Figure 5 For example, the first end of the conductive spring 127 can be the bottom end of the conductive spring 127, and the second end of the conductive spring 127 can be the top end of the conductive spring 127. The trigger 126 is movably connected to the fixed base 130, and the trigger 126 is movably disposed through the pressure cover 135 and the first base 134.

[0055] like Figure 2 As shown, when the area of ​​the first water inlet 118 blocked by the piston 112 is at its maximum, both ends of the trigger 126 abut against the piston 112 and the conductive spring 127 respectively, and the second end of the conductive spring 127 contacts the battery 129. At this time, the battery 129, circuit board 131, conductive spring 127, and working element 128 together form a circuit, and the battery 129 supplies power to the working element 128. And as... Figure 1 As shown, when the piston 112 is in the initial position (e.g., no water enters the protective assembly 101), the second end of the conductive spring 127 is not in contact with the battery 129, the circuit is broken, and the battery 129 does not supply power to the working element 128.

[0056] like Figure 5As shown, the circuit board 131 may include a first substrate 132 and a second substrate 133, with a battery 129 located between the first substrate 132 and the second substrate 133. The first substrate 132 is annular, with a first end of a conductive spring 127 connected to the first substrate 132, and a second end of the conductive spring 127 passing through a hole located at the center of the first substrate 132. The battery 129 may be a button cell battery, with one electrode at the left end and the left side of the battery 129 used to contact the second end of the conductive spring 127. The other electrode of the battery 129 is at the right end and is used to connect to a contact or pad (not shown) on the second substrate 133. The working element 128 is a light-emitting diode (LED), which emits light when powered. One pin of the working element 128 wraps around the left side surface of the first substrate 132 and connects to it, while the other pin of the working element 128 connects to the second substrate 133. In this way, when the second end of the conductive spring 127 contacts the battery 129, the battery 129, circuit board 131, conductive spring 127, and working element 128 together form a circuit. The light-emitting part of the working element 128 can extend from the right end of the second base 136 (e.g., Figure 5 (as shown), thus being exposed to the outside of the housing 102.

[0057] In other embodiments, if the operating element 128 provides a sound prompt to the user, the operating element 128 may be configured as a speaker, buzzer, etc., that can be activated when powered on.

[0058] The two ends of the elastic element 116 can respectively abut against the reminder module 115 and the piston 112; more specifically, the elastic element 116 can abut against the first seat 134. In other embodiments, the two ends of the elastic element 116 can also be connected to the inner surface of the main body 104 and the piston 112, respectively. Since the piston 112 will come into contact with water, at least one of the piston 112 and the trigger element 126 is an insulating element to prevent leakage or short circuit in the reminder module 115.

[0059] Figures 6 to 7 A shower device 201 according to an embodiment of the present invention is shown. The shower device 201 includes a water supply pipe 203, a shower head 204, and a protective component 101 as described in any of the above embodiments. One end of the water supply pipe 203 is connected to the water inlet 119, and the shower head 204 is connected to the water outlet 109. Due to the explosion-proof function of the protective component 101, the shower head 204, located downstream of the protective component 101, is not prone to bursting. Moreover, since the protective component 101 does not spray water into the surrounding environment when it is working, the user will not experience water spraying from the protective component 101 into the surrounding environment while showering, and items outside the shower area (such as clothes, towels, etc. hanging outside the shower area) will not be wetted by the water spray from the protective component 101.

[0060] like Figure 6 As shown, the shower device 201 also includes a shower faucet 202 installed on the water supply pipe 203. The shower faucet 202 is used to control the flow rate of water to the shower head 204. In this embodiment, the shower head 204 is an overhead shower head. In some other embodiments not shown, the shower head 204 may also be a handheld shower head. Figure 3 As shown, the outer casing 102 has an internal thread at the water inlet 119 and an external thread at the water outlet 109, so that the protective component 101 can be connected to the water supply pipe 203 and the shower head 204. Figure 7 As shown, the inlet ball head 205 of the shower head 204 can be connected to the outlet 109.
