Description

Technical Field

[0001] The present application relates to the technical field of pressure detection, and in particular to a pressure detection device. Background Art

[0002] Pressure detection devices are generally used to detect the pressure they are subjected to. For example, a grip ball is generally used to exercise hand strength and can detect the grip force exerted by the user's hand during exercise.

[0003] Most current pressure detection devices have a flexible housing. When the pressure detection device is subjected to pressure, the flexible housing deforms. This deformed flexible housing directly or indirectly applies pressure to a pressure sensor within the pressure detection device, allowing the pressure sensor to detect the magnitude of the pressure applied to the pressure detection device. The pressure sensor is typically mounted directly on the flexible housing or within a housing formed by the flexible housing. The flexible housing and pressure sensor are connected via an elastic member, for example, to transmit the pressure applied to the flexible housing.

[0004] However, these current pressure detection devices primarily utilize contact transmission, which results in wear and tear between contacting components after repeated use. This, combined with the friction between the components, ultimately results in insufficient detection accuracy for these current pressure detection devices. Utility Model Content

[0005] The purpose of the present application is to provide a pressure detection device, which can improve the detection accuracy of the pressure detection device by transmitting the pressure between the housing and the pressure sensor through gas.

[0006] The pressure detection device provided in the present application includes a shell, an integrated component, a pressure sensor and a control component; the shell has a first accommodating space inside and is made of a flexible material; a mounting hole is provided on the shell; the integrated component is located in the first accommodating space and is sealed to the edge of the mounting hole to form a sealed space with the shell; the pressure sensor and the control component are respectively arranged on the integrated component; the pressure sensor is electrically connected to the control component; the control component is configured to obtain the air pressure value in the sealed space detected by the pressure sensor, and output the pressure value of the pressure applied to the shell according to the air pressure value.

[0007] The aforementioned pressure detection device forms a sealed space between the integrated component and the housing. When subjected to pressure, the housing deforms, causing the air pressure within the sealed space to change. A pressure sensor, mounted on the integrated component and not in direct contact with the housing, detects the air pressure and can then determine the magnitude of the pressure acting on the pressure detection device. This eliminates the need for direct or indirect contact between the pressure sensor and the housing, thus avoiding the effects of wear and friction between components caused by transmission on detection accuracy. This, in turn, improves the detection accuracy of the pressure detection device.

[0008] Optionally, the integrated component includes a first inner shell and a second inner shell; the first inner shell and the second inner shell are sealed and combined to form a second accommodating space; the control component is arranged in the second accommodating space; the pressure sensor is arranged on the outer wall of the first inner shell or the outer wall of the second inner shell.

[0009] The above-mentioned pressure detection device forms a sealed second storage space by the first inner shell and the second inner shell, and the control component is arranged in the second storage space. Since the second storage space is isolated from the sealed space formed by the integrated component and the outer shell, when the air pressure in the sealed space changes, the air pressure inside the second storage space will hardly be affected and will change accordingly. Ultimately, damage to the electronic components on the control component and the connection circuits between the electronic components caused by the change in the air pressure in the second storage space is avoided to a certain extent. In addition, since the control component usually needs to be directly or indirectly connected to the charger, pressure data analysis device, etc. outside the outer shell, the airtightness of the sealed space is further ensured by isolating the second storage space from the sealed space formed by the integrated component and the outer shell, which further improves the detection accuracy of the pressure detection device.

[0010] Optionally, the integrated component further includes sealant; the sealant fills a gap at the connection between the first inner shell and the second inner shell, and a gap at the connection between the first inner shell or the second inner shell and the pressure sensor.

[0011] The pressure detection device uses sealant to bond the first inner shell and the second inner shell to achieve a sealed connection between the first inner shell and the second inner shell, which simplifies the process of connecting the first inner shell and the second inner shell, thereby reducing the manufacturing cost of the pressure detection device.

[0012] Optionally, the integrated component further includes a sealing filling body; the sealing filling body wraps the portion of the integrated component located in the first accommodating space, except for the air pressure sensing surface of the pressure sensor; wherein the pressure sensor has a pressure sensing surface, and the air pressure sensing surface is located in the middle of the pressure sensing surface; the sealing filling body also fills the connection between the integrated component and the outer shell.

[0013] The above-mentioned pressure detection device uses a sealing filler to wrap the integrated component except for the position of the air pressure sensing surface, and fills it at the connection between the integrated component and the shell, thereby achieving a seal between the integrated component and the shell, as well as a seal of the internal space of the integrated component. In addition, through the wrapping of the sealing filler, since the stress tolerance of the sealing filler is basically the same at all parts of the sealing filler, the stress tolerance of the combined structure of the integrated component and the sealing filler tends to be consistent at all parts, which accordingly avoids the situation where the parts with lower stress tolerance are damaged first under the action of air pressure due to inconsistent stress tolerance. In other words, by improving the structural stability of the sealing inside the integrated component, the airtightness of the internal space of the integrated component is improved, and ultimately the airtightness of the sealed space formed by the integrated component and the shell is improved, further improving the detection accuracy of the pressure detection device.

[0014] Optionally, the control assembly includes electrical components; the integrated component has an integrated gap; wherein the integrated gap is the gap between the electrical components on the integrated component; the sealing filling body also fills the integrated gap.

[0015] The pressure detection device fills the gaps between the electrical components through the sealing filling body, thereby improving the installation stability of the electrical components on the integrated component.

[0016] Optionally, the sealing filling body and the shell are an integral structure.

[0017] The pressure detection device mentioned above improves the integrity and structural strength of the sealing filling body and the outer shell by integrally forming the sealing filling body and the outer shell, reduces material waste, reduces corresponding process links, and thus improves production efficiency.

[0018] Optionally, the sealing filling body is a flexible member or an elastic member with a deformable amount.

[0019] The above-mentioned pressure detection device improves the adaptability of the sealing filling body to the spatial shape of the sealing filling position by adopting a flexible or elastic part with a deformable amount as the sealing filling body, so that the sealing filling position can be better filled, which further improves the sealing performance; at the same time, the deformable flexible or elastic part can absorb the force of the air pressure in the sealed space on the integrated part to a certain extent when the outer shell is squeezed and the pressure in the sealed space changes, thereby avoiding damage to the structure of the integrated part under the action of long-term air pressure change force, so that the pressure detection device of the present application has strong structural stability and can meet the requirements of durability.

[0020] Optionally, the device further includes a plug body; the shape of the plug body matches the mounting hole, and is used to be inserted into the mounting hole to cover the mounting hole.

[0021] The above-mentioned pressure detection device is configured with a plug body for covering the mounting hole, so that the part of the integrated component and the control component integrated on the integrated component that is exposed outside the shell through the mounting hole can be covered by the plug body, thereby playing a protective role such as dustproof and waterproof.

[0022] Optionally, the control assembly includes an electrical socket; the electrical socket is located on an exposed surface of the integrated component exposed outside the accommodation space; the orientation of the electrical socket is consistent with the orientation of the exposed surface;

[0023] The above-mentioned pressure detection device realizes functions such as charging or data transmission of the pressure detection device by arranging an electrical socket on the exposed surface of the integrated component exposed outside the accommodation space.

[0024] Optionally, an insertion portion matching the electrical socket is provided on the plug body; the insertion portion is configured to be inserted into the electrical socket when the plug body is inserted into the mounting hole.

[0025] The pressure detection device, with the plug body inserted into the mounting hole and the insertion portion inserted into the electrical jack, provides further protection against dust, water, and air. This further protects the integrated component and the portion of the control assembly integrated therein that is exposed outside the housing through the mounting hole. Furthermore, the fit between the plug body and the mounting hole improves the installation stability between the plug body and the control assembly.

[0026] Optionally, the device further comprises a connecting rope; one end of the connecting rope is connected to the plug body; and the other end of the connecting rope is connected to the integrated component.

[0027] The pressure detection device is connected to the plug body and the integrated component via a connecting rope, which plays a role in preventing the plug body from being lost.

[0028] Optionally, the other end of the connecting rope is connected to the integrated component through a conical head; wherein, the conical head is made of elastic material; a connecting hole is provided on the exposed surface of the integrated component exposed outside the accommodating space; the diameter of the connecting hole is smaller than the maximum diameter of the conical head; and the conical head is inserted into the interior of the integrated component through the connecting hole.

[0029] The pressure detection device is connected to the connection hole via a connecting rope in the shape of a conical head, which facilitates the connection between the conical head and the connection hole during assembly and improves the connection stability between the conical head and the connection hole after assembly.

[0030] Optionally, an air injection hole is further provided on the shell; the air injection hole passes through the outer surface of the shell and extends to the sealed space; a one-way ventilation air core is provided in the air injection hole; the ventilation direction of the air core is from outside the sealed space to inside the sealed space.

[0031] The aforementioned pressure detection device, by providing an air injection hole in the housing, allows for the possibility of gas leakage within the sealed space due to a decrease in the sealing performance of the sealed space, allowing air to be re-injected into the sealed space through the air injection hole to restore the air pressure within the sealed space. This further improves the detection accuracy of the pressure detection device by ensuring normal air pressure within the sealed space. Furthermore, by providing a one-way air core within the air injection hole, a plug for plugging the air injection hole is eliminated, thereby eliminating the need to plug the air injection hole after air injection is completed. This improves the ease of use of the pressure detection device.

[0032] Optionally, the outer wall of the shell is provided with a plurality of protrusions.

[0033] The above-mentioned pressure detection device improves the anti-slip property of the outer shell of the pressure detection device through several protrusions on the outer shell. It also has a massage function during pressure detection or when pressure detection is not required, thereby increasing the versatility of the pressure detection device of the present application.

[0034] In summary, the pressure detection devices provided by various embodiments of the present application utilize gas to transmit pressure between the housing and the pressure sensor, thereby avoiding the effects of wear and friction between components caused by transmission on detection accuracy. Consequently, the detection accuracy of the pressure detection device is improved. By forming a sealed second accommodation space between the first and second inner housings and locating the control assembly within the second accommodation space, damage to the electronic components of the control assembly and the connecting circuits between the electronic components due to changes in the air pressure in the second accommodation space is avoided to a certain extent, further ensuring the airtightness of the sealed space, thereby further improving the detection accuracy of the pressure detection device. By using a sealing filler to wrap the integrated component except for the air pressure sensing surface and filling the connection between the integrated component and the housing, the stress tolerance of the combined structure of the integrated component and the sealing filler is made uniform across all locations. This avoids the situation where areas with lower stress tolerance are damaged first under the action of air pressure due to inconsistent stress tolerance, thereby further improving the detection accuracy of the pressure detection device by improving the sealing of the sealed space formed by the integrated component and the housing. By integrating the sealing filler into the housing, the integrity and structural strength of the seal are improved, while material waste and associated process steps are reduced, thereby improving production efficiency. The portion exposed outside the housing through the mounting hole can be covered by the plug body, providing protection against dust and water. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Please refer to Figures 1 to 3 , Figure 1 This is a first cross-sectional view of the pressure detection device 100 provided in an embodiment of the present application; Figure 2 This is a first exploded view of the pressure detection device 100 provided in an embodiment of the present application; Figure 3 It is a cross-sectional view of the integrated component 120 in the pressure detection device 100 provided in an embodiment of the present application. The pressure detection device 100 provided in an embodiment of the present application may include a housing 110, an integrated component 120, a pressure sensor 130 and a control component 140. The housing 110 may have a first accommodation space inside and be made of a flexible material. A mounting hole 111 is provided on the housing 110. The integrated component 120 may be located in the first accommodation space and be sealed to the edge of the mounting hole 111 to form a sealed space with the housing 110. The pressure sensor 130 and the control component 140 are respectively arranged on the integrated component 120. The pressure sensor 130 is electrically connected to the control component 140. The control component 140 can be configured to obtain the air pressure value in the sealed space detected by the pressure sensor 130, and output the pressure value of the pressure exerted on the housing 110 according to the air pressure value.

[0054] The shape of the housing 110 can be spherical or any other shape that can easily fit the external pressure target. The flexible material can be rubber, plastic, silicone or any other composite material with a certain degree of flexibility and bendability.

[0055] The integrated component 120 can be in the shape of a strip, or a sphere or a cylinder, etc. It can form a sealed space with the outer shell 110 by being sealedly connected to the edge of the mounting hole 111 in the first accommodating space. The outer shell 110 can be provided with a gas injection hole 112 so that gas can be added to the sealed space at any time to ensure the internal pressure. The outer shell 110 may also not be provided with a gas injection hole 112, that is, after ensuring the air pressure in the sealed space, the sealed space is permanently sealed directly by the sealed connection between the integrated component 120 and the outer shell 110. The integrated component 120 can be provided with a mounting groove for mounting a pressure sensor 130 and other control components 140. The control component 140 may include a circuit board integrated with a controller, a communication module, a power module, etc., and a battery.

[0056] The pressure sensor 130 may be an air pressure sensor, for example, an air pressure sensor of model WF183DE 01BA.

[0057] During operation of the pressure detection device 100, the shape of the housing 110 changes when it is subjected to pressure, causing the air pressure within the sealed space formed by the integrated component 120 and the housing 110 to change. The changed air pressure can be detected by the pressure sensor 130. The controller or other electronic components in the control assembly 140 can determine and output the pressure applied to the pressure detection device 100 based on a pre-stored mapping relationship between the air pressure value and the pressure applied to the housing 110.

[0058] In the above implementation process, a sealed space is formed between the integrated component 120 and the housing 110. When subjected to pressure, the housing 110 deforms, causing the air pressure within the sealed space to change. The pressure sensor 130, which is mounted on the integrated component 120 and not in direct contact with the housing 110, detects the air pressure and can then determine the pressure applied to the pressure detection device 100. There is no need for the pressure sensor 130 to be in direct or indirect contact with the housing 110, thereby avoiding the effects of wear and friction between components caused by transmission on detection accuracy. This, in turn, improves the detection accuracy of the pressure detection device 100.

[0059] Please refer to Figure 4 and Figure 5 , Figure 4 is a three-dimensional diagram of the integrated component 120 in the pressure detection device 100 provided in an embodiment of the present application; Figure 5 This is a disassembled diagram of the integrated component 120 in the pressure detection device 100 provided in an embodiment of the present application. In some optional embodiments, the integrated component 120 may include a first inner shell 121 and a second inner shell 122. The first inner shell 121 and the second inner shell 122 may be sealed together to form a second storage space. The control assembly 140 may be disposed in the second storage space. The pressure sensor 130 may be disposed on the outer wall of the first inner shell 121 or the outer wall of the second inner shell 122.

[0060] The integrated component 120 formed by the first inner shell 121 and the second inner shell 122 can be cylindrical, rectangular, or spherical, etc. The first inner shell 121 and the second inner shell 122 can be sealed and combined by welding, bonding, or integral molding.

[0061] In the above implementation process, the first inner shell 121 and the second inner shell 122 form a sealed second storage space, and the control component 140 is disposed in the second storage space. Since the second storage space is isolated from the sealed space formed by the integrated component 120 and the outer shell 110, when the air pressure in the sealed space changes, the air pressure inside the second storage space is hardly affected and changes accordingly. Ultimately, damage to the electronic components on the control component 140 and the connecting circuits between the electronic components caused by the change in the air pressure in the second storage space is avoided to a certain extent. In addition, since the control component 140 usually needs to be directly or indirectly connected to a charger, a pressure data analysis device, etc. outside the outer shell 110, the airtightness of the sealed space is further ensured by isolating the second storage space from the sealed space formed by the integrated component 120 and the outer shell 110, which in turn further improves the detection accuracy of the pressure detection device 100.

[0062] Please continue to refer to Figure 4 and Figure 5 In some optional embodiments, the integrated component 120 may further include a sealant (not shown). The sealant may fill the gaps at the connection between the first inner shell 121 and the second inner shell 122, and at the connection between the first inner shell 121 or the second inner shell 122 and the pressure sensor 130.

[0063] That is to say, the first inner shell 121 can be sealed and connected to the second inner shell 122 by sealant, and the pressure sensor 130 can also be installed on the integrated component 120 by sealant. At this time, the pressure sensor 130 only needs to ensure that its effective pressure detection surface is located in the sealed space.

[0064] In the above implementation process, the first inner shell 121 and the second inner shell 122, and the pressure sensor 130 and the first inner shell 121 or the second inner shell 122 are bonded by using sealant to achieve a sealed connection between the first inner shell 121 and the second inner shell 122, and between the pressure sensor 130 and the first inner shell 121 or the second inner shell 122, thereby simplifying the process of combining the first inner shell 121 and the second inner shell 122, and the pressure sensor 130 and the first inner shell 121 or the second inner shell 122, thereby reducing the manufacturing cost of the pressure detection device 100.

[0065] Please refer to Figure 6 and Figure 7 , Figure 6 is an exploded view of the pressure detection device 100 provided in an embodiment of the present application; Figure 7This is a second cross-sectional view of the pressure detection device 100 provided in an embodiment of the present application. In some optional embodiments, the integrated component 120 may further include a sealing filling body 124. The sealing filling body 124 wraps the integrated component 120 and may be located in the first accommodating space, excluding the air pressure sensing surface 1311 of the pressure sensor 130. The pressure sensor 130 may have a pressure sensing surface 131, and the air pressure sensing surface 1311 may be located in the pressure sensing surface 131. The sealing filling body 124 may also fill the connection between the integrated component 120 and the housing 110.

[0066] The sealing filler 124 can be made of materials such as silicone (rubber), gel, latex, TPU (Thermoplastic Polyurethane), etc.

[0067] In other words, the sealing filling body 124 not only fills the connection between the integrated component 120 and the housing 110, but also wraps the integrated component 120. However, in order to enable the pressure sensor 130 to detect changes in air pressure, the sealing filling body 124 exposes the side of the pressure sensor 130 that can sense changes in air pressure to the sealed space during the wrapping and integration process. For example, the pressure sensing surface 131 of the pressure sensor 130 is a square, and the air pressure sensing surface 1311 can be an inscribed circle of the square. In this way, the connection between the pressure sensor 130 and the integrated component 120 and the control component 140 can be sealed by the sealing filling body 124, and the pressure sensor 130 can be prevented from detecting the air pressure in the sealed space.

[0068] In the above implementation process, the sealing filler 124 is used to wrap the integrated component 120 except for the position of the air pressure sensing surface 1311, and is filled in the connection between the integrated component 120 and the housing 110, thereby achieving the sealing between the integrated component 120 and the housing 110, as well as the sealing of the internal space of the integrated component 120. In addition, through the wrapping of the sealing filler 124, since the stress tolerance of each part of the sealing filler 124 is basically the same, the stress tolerance of the combined structure of the integrated component 120 and the sealing filler 124 tends to be consistent at each part, which accordingly avoids the situation where the parts with lower stress tolerance are damaged first under the action of air pressure due to inconsistent stress tolerance. In other words, by improving the structural stability of the sealing inside the integrated component 120, the airtightness of the internal space of the integrated component 120 is improved, and ultimately the airtightness of the sealed space formed by the integrated component 120 and the housing 110 is improved, further improving the detection accuracy of the pressure detection device 100.

[0069] In some optional embodiments, the control assembly 140 includes electrical components; the integrated component 120 has an integrated gap; wherein the integrated gap is the gap between the electrical components on the integrated component 120; and the sealing filler 124 also fills the integrated gap.

[0070] That is, after the electrical components are installed in the integrated body, the sealing filling body 124 can be wrapped outside the integrated body and fill the gaps between the electrical components.

[0071] During the above implementation process, the gaps between the electrical components are filled by the sealing filler 124, thereby improving the installation stability of the electrical components on the integrated component 120. Figure 7 In some optional embodiments, the sealing filling body 124 and the shell 110 can be an integral structure.

[0072] That is to say, the sealing filling body 124 and the housing 110 can be integrally formed by opening a corresponding mold.

[0073] In the above implementation process, the sealing filling body 124 and the shell 110 are integrally formed, thereby improving the integrity and structural strength therebetween, reducing material waste, reducing corresponding process links, and thus improving production efficiency.

[0074] In some optional embodiments, the sealing filling body 124 is a flexible or elastic member with a deformable amount.

[0075] The flexible or elastic member with a deformable amount may be made of materials such as silicone (rubber), gel, latex, TPU (Thermoplastic Polyurethane), etc.

[0076] During the above-mentioned implementation process, by adopting a flexible or elastic part with a deformable amount as the sealing filling body 124, the adaptability of the sealing filling body 124 to the spatial shape of the sealing filling position is improved, so that the sealing filling position can be better filled, that is, the sealing performance is further improved; at the same time, the deformable flexible or elastic part can absorb the force of the air pressure in the sealed space on the integrated part 120 to a certain extent when the shell 110 is squeezed and the pressure in the sealed space changes, thereby avoiding damage to the structure of the integrated part 120 under the action of long-term air pressure changes, so that the pressure detection device of the present application has strong structural stability and can meet the requirements of durability.

[0077] Please refer to Figure 8 and Figure 9 , Figure 8 This is a third cross-sectional view of the pressure detection device 100 provided in an embodiment of the present application; Figure 9This is a second exploded view of the pressure detection device 100 provided in an embodiment of the present application. In some optional embodiments, the pressure detection device 100 provided in an embodiment of the present application may further include a plug 150. The plug 150 may be shaped to match the mounting hole 111 and may be inserted into the mounting hole 111 to obstruct the mounting hole 111.

[0078] The plug body 150 can be made of rubber, plastic, silica gel or other composite materials with good flexibility and bendability. When the mounting hole 111 is circular, the plug body 150 can also be circular accordingly.

[0079] During the above implementation process, a plug body 150 is configured to cover the mounting hole 111, so that the portion of the integrated component 120 and the control component 140 integrated on the integrated component 120 that is exposed outside the outer shell 110 through the mounting hole 111 can be covered by the plug body 150, thereby achieving dustproof, waterproof and other protective effects.

[0080] Please combine Figure 8 and Figure 9 Reference Figure 10 , Figure 10 This is a perspective view of the plug body 150 in the pressure detection device 100 provided in an embodiment of the present application. In some optional embodiments, the control assembly 140 may include an electrical jack 141. The electrical jack 141 may be located on the exposed surface of the integrated component 120 that is exposed outside the storage space. The orientation of the electrical jack 141 may be consistent with the orientation of the exposed surface.

[0081] Exemplarily, the electrical socket 141 is a Type-C charging interface, and the insertion portion 151 may be a flat cylindrical shape.

[0082] In the above implementation process, by providing the electrical socket 141 on the exposed surface of the integrated component 120 outside the accommodation space, functions such as charging or data transmission of the pressure detection device 100 are realized.

[0083] Please continue to refer to Figures 8 to 10 In some optional embodiments, the plug body 150 may be provided with an insertion portion 151 that matches the electrical socket 141. The insertion portion 151 may be configured to be inserted into the electrical socket 141 when the plug body 150 is inserted into the mounting hole 111.

[0084] As an optional embodiment, a switch hole may be provided on the plug body, and the switch element on the control assembly 140 may be exposed outside the pressure detection device 100 through the switch hole, so that the user can operate the switch element.

[0085] In the above implementation, by inserting the plug body 150 into the mounting hole 111 and inserting the insertion portion 151 into the electrical jack 141, the electrical jack 141 is further protected from dust, water, and air. This further protects the manifold 120 and the portion of the control assembly 140 integrated therein that is exposed outside the housing 110 through the mounting hole 111. Furthermore, the mating fit between the plug body 150 and the mounting hole 111 improves the installation stability between the plug body 150 and the control assembly.

[0086] Please continue to refer to Figures 8 to 10 In some optional embodiments, the pressure detection device 100 provided in the embodiment of the present application may further include a connecting rope 160. One end of the connecting rope 160 may be connected to the plug body 150. The other end of the connecting rope 160 may be connected to the integrated component 120.

[0087] In the above implementation process, the plug body 150 is connected to the integrated component 120 via the connecting rope 160, which plays a role in preventing the plug body 150 from being lost.

[0088] Please continue to refer to Figures 8 to 10 In some optional embodiments, the other end of the connecting cord 160 is connected to the integrated component 120 via a conical head 161. The conical head 161 can be made of an elastic material. A connecting hole 125 can be provided on the exposed surface. The diameter of the connecting hole 125 can be smaller than the maximum diameter of the conical head 161. The conical head 161 can be inserted into the integrated component 120 through the connecting hole 125.

[0089] Although the diameter of the maximum diameter of the conical head, that is, the bottom of the conical head portion 161, is larger than the diameter of the connecting hole 125, the elasticity of the conical head portion 161 can be utilized to force it into the mounting hole 111. Subsequently, the bottom of the conical head portion 161 abuts against the edge of the connecting hole 125 to prevent the conical head portion 161 from sliding out of the connecting hole 125.

[0090] During the above implementation process, the connecting rope 160 in the shape of the conical head 161 is connected to the connecting hole 125, which facilitates the connection between the conical head 161 and the connecting hole 125 during the assembly process and improves the connection stability between the conical head 161 and the connecting hole 125 after assembly.

[0091] Please refer to Figure 7 and Figure 8 In some optional embodiments, the housing 110 may further be provided with an air injection hole 112. The air injection hole 112 may penetrate the outer surface of the housing 110 and may extend into the sealed space. A one-way ventilating air core 170 may be provided in the air injection hole 112. The ventilation direction of the air core 170 may be from outside the sealed space to inside the sealed space.

[0092] As time goes by and the number of uses increases, the sealing of the sealed space may decrease, resulting in leakage of gas inside the sealed space. In this case, gas can be injected into the sealed space again through the gas injection hole 112 to restore the air pressure in the sealed space.

[0093] During the above implementation, by providing the gas injection hole 112 on the housing 110, in the event of a gas leak in the sealed space due to a decrease in the sealing performance of the sealed space, gas can be re-injected into the sealed space through the gas injection hole 112 to restore the air pressure in the sealed space. This further improves the detection accuracy of the pressure detection device 100 by ensuring the normal air pressure in the sealed space. Furthermore, by providing a one-way ventilated gas core 170 in the gas injection hole 112, a plug for plugging the gas injection hole 112 is eliminated, and accordingly, the operation of plugging the gas injection hole 112 with a plug after gas injection is completed is eliminated. This improves the ease of use of the pressure detection device 100.

[0094] Please continue to refer to Figures 8 to 10 In some optional embodiments, the outer wall of the housing 110 may be provided with a plurality of protrusions 123 .

[0095] The protrusion 123 may be a spur protruding from the shell, and its material may also be rubber, plastic, silicone or other composite materials with certain flexibility and bendability.

[0096] During the above implementation process, the anti-slip property of the outer shell 110 of the pressure detection device 100 is improved by providing a number of protrusions 123 on the outer shell 110. The device also has a massage function during pressure detection or when pressure detection is not required, thereby increasing the versatility of the pressure detection device of the present application.

[0097] In summary, the pressure detection device 100 provided in each embodiment of the present application avoids the influence of wear between components and friction between components caused by transmission on the detection accuracy by transmitting the pressure between the gas shell 110 and the pressure sensor 130. Correspondingly, the detection accuracy of the pressure detection device 100 is improved. The sealed second storage space formed by the first inner shell 121 and the second inner shell 122, and the control component 140 is arranged in the second storage space, which to a certain extent avoids the damage to the electronic components on the control component 140 and the connection circuits between the electronic components due to the change of the air pressure in the second storage space, further ensures the airtightness of the sealed space, and further improves the detection accuracy of the pressure detection device 100. By using the sealing filler 124 to wrap the integrated component 120 except for the position of the air pressure sensing surface 1311, and filling the connection between the integrated component 120 and the housing 110, the stress tolerance of the combined structure of the integrated component 120 and the sealing filler 124 is made consistent at all locations, thereby avoiding the situation where the parts with lower stress tolerance are damaged first under the action of air pressure due to inconsistent stress tolerance. By improving the sealing of the sealed space formed by the integrated component 120 and the housing 110, the detection accuracy of the pressure detection device 100 is further improved. By integrally forming the sealing filler 124 with the housing 110, the integrity and structural strength between them are improved, and the waste of materials and the corresponding process links are reduced, thereby improving production efficiency. The part exposed outside the housing 110 through the mounting hole 111 can be covered by the plug body 150, thereby playing a protective role such as dustproof and waterproof.

[0098] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
